Description

Description: Washing toilet, drainage device therefor, and toilet having the same

The present invention relates to a flush toilet that induces a siphon action to discharge waste in a ball portion, a drainage device for inducing the siphon action, and a toilet in which the flush toilet is installed. Background art

In recent years, there has been an increasing demand for saving water used for washing in flush toilets. In order to meet this demand for water saving, the amount of washing water should be reduced. However, simply reducing the amount of washing water flowing into the bowl not only results in insufficient washing of the bowl, but also lacks certainty in transporting and discharging filth along with the washing water to the outside of the toilet. . For this reason, the trap shape of the toilet body is devised so as to induce a siphon action when the washing water passes through, and the siphon action is used to suction the stored water to achieve water saving. I have.

By the way, it is assumed that the trap of the toilet body is bent from the toilet installation floor to a predetermined height in the toilet. Therefore, the arrangement of the mechanism that induces the siphon effect is also restricted by such trap formation. For this reason, at present, only a siphon-inducing mechanism is installed in a trap subject to the above restrictions. Also, drainage sockets are being used to induce siphon action. For example, Japanese Unexamined Patent Publication No. Hei 8-332613 proposes a drainage socket shown in FIG. In this conventional flush toilet, the discharge port 102 J of the toilet body 100 J is connected to a drain pipe P arranged on the floor FL via a drain socket 110 J. The drain socket 110J is formed in a shape bent in the longitudinal direction of the toilet body 100J. Drain socket 1 1 0J forms a bent socket channel 112J and has a concave trap receiving portion 111J on the wall thereof. As a result, the drainage socket 110J generates a turbulent flow in the curved flow passage portion and the concave trap receiving portion, thereby facilitating the generation of the siphon.

A throttle section 1 16 J is provided between the drain socket 1 110 J and the drain pipe P, that is, between the outlet 1 114 J of the socket channel 1 1 2 J and the upper end of the drain pipe. ing. The constricted portion 1 16 J acts so as to temporarily retain the washing water flowing from the socket flow channel 112 J to the drain pipe P to promote generation of a siphon.

However, the conventional constricted portion 116J is formed separately from the drainage socket 110J and is only interposed between the upper end opening of the drainage pipe P. When it was received, there was a problem that it was easy to be displaced and to fall into the drain pipe P. Such misalignment of the diaphragm reduces the action of generating a siphon. Also, the dropping of the restriction to the drain pipe will cause the drain pipe P to be clogged. Furthermore, the work of assembling such a narrowed portion at a predetermined position is troublesome.

In view of these points, an object of the present invention is to increase the efficiency of suction of the stored water in the ball portion by the siphon action regardless of the trap shape.

It is another object of the present invention to provide a drainage socket which can realize the early generation of a siphon without a displacement of a throttle part and which is excellent in construction workability.

In the above drain socket 110 J, not only the pipe is bent, but the concave trap receiving part 1 1 1 J is formed on the inner wall surface, which complicates the pipe structure. . For this reason, when the drainage socket 110 J is formed by injection molding or the like, the die for the die becomes complicated. It is necessary to change the shape of the drainage socket 110 J of such a complicated shape from the viewpoint of formability, that is, the drainage socket 110 J has an optimal shape for inducing a siphon. There was a problem of being restricted.

Based on these points, the present invention has a simple structure and is easy to manufacture, Moreover, it is another object of the present invention to provide a drainage socket capable of quickly generating a siphon and obtaining a large siphon power.

By the way, the distance from the floor or wall where the toilet is installed (hereinafter referred to as the installation surface) to the end of the drainage channel differs depending on the type of toilet installed. Therefore, in order to be able to install such various types of toilets with drainage sockets interposed, it was necessary to prepare a plurality of drainage sockets having different heights as products. As a result, it was not possible to efficiently reduce product types.

In addition, since toilets are designed and manufactured independently by many companies around the world, it was practically difficult to prepare drainage sockets for all toilets that could be installed in advance. For example, if the distance from the installation surface of the toilet to the end of the drainage channel is longer than the length of the drainage socket, lay a plate or the like with a thickness that is not long enough under the drainage socket. This has been a factor that hindered construction efficiency. On the other hand, if the distance from the toilet installation surface to the end of the drainage channel is shorter than the length of the drainage socket, the method of connecting the toilet to the wastewater pipe must be changed to a method using a flange. It was inconvenient for construction. As described above, the connection function of the drainage socket described above cannot be exhibited depending on the type of the toilet connected.

In addition, conventional drainage sockets use a hollow cylindrical part formed in the socket as a water flow path, and the position of the throttle provided in this flow path is changed for each construction site. I couldn't. For example, if the installed toilet is a toilet that uses the siphon action to clean, the position of the throttle section should be changed below the floor surface, and the accumulated water and flush water generated after the siphon action occurs Although it is possible to increase the suction force of the air, it was not possible to make such a change in the past. As described above, in the conventional drainage socket, even if the siphon effect is maintained for a long time by the siphon continuation function, a considerable loss occurs in the suction power of the stored water and the washing water caused by the continuation. Therefore, an object of the present invention is to provide a drainage socket that can respond to various types of toilets to be installed and the situation of the installation site from various aspects.

By the way, the siphon function disappears when the siphon pipe is not filled with water (wash water) due to air entry, flow rate reduction, and the like. In the above-mentioned publication, when the amount of washing water in the toilet bowl decreases and the amount of washing water flowing into the drainage socket decreases, the amount of water flowing in the bent socket flow path changes direction. Therefore, as the degree of change in the water flow direction becomes smaller, the flush water flows directly into the discharge pipe outside the toilet. In such a case, the occupied area of the washing water in the cross section of the pipeline is reduced, so that air is likely to enter from the downstream side, so that the siphon cannot be maintained and the siphon action is lost. In general, dirt floating on the water in the bowl (eg, dirt paper or floating diarrheal stool) is sucked into the trap later in the siphon and discharged. For this reason, with the conventional technology in which the siphon is easily lost at the end of the siphon, which causes a decrease in the flow rate, these suspended solids may not be able to be completely sucked and discharged.

In view of these points, an object of the present invention is to increase the suction efficiency of the stored water in the ball portion at the end of the siphon.

Also, in flush toilets that use the siphon action, the siphon is started at a high speed at the start of cleaning, and the filth quickly flows with a high head pressure and a low pressure loss. It is preferable to save water by discharging water. However, when washing water is flushed for a short time to save water, large filth and paper can be quickly discharged, but some filth floating in the ball remains and is not discharged May be.

In view of these points, an object of the present invention is to promptly discharge wastes floating in the ball portion. Disclosure of the invention

In order to solve at least part of the above-mentioned problems, the first water of the present invention is used. The toilet bowl is

A flush toilet having a ball portion for leaving washing water as stored water at the time of non-washing, and a trapping means for forming a conduit for discharging fresh washing water passed through the ball portion together with the stored water to the outside. So,

The trap means,

An ascending pipeline portion having an ascending pipeline in communication with the ball portion;

In addition to forming a drainage pipe for guiding the washing water that has passed through the rising pipe part to the outside of the toilet, the washing water that passes through the drainage pipe is temporarily retained so as to have a siphon action. A drain pipe section having a retention means for inducing,

The drainage pipe section,

A protruding pipe portion installed so as to protrude part of the drainage pipe below the toilet installation floor surface.

Having the retaining means in the projecting conduit portion

It is characterized by the following.

In the first flush toilet of the present invention having the above structure, the trap means is constituted by an ascending pipe and a drain pipe following the ascending pipe, and a part of the drain pipe is projected downward from the toilet installation floor surface to protrude the pipe. The siphon action is induced by the retaining means at the projecting conduit. Therefore, the difference between the flush water level temporarily retained by the retaining means in the projecting pipe section and the pooled water level in the ball section can be increased, and the head difference when the siphon action is induced can be increased accordingly. Thus, the suction power of the stored water and the suction efficiency by the siphon action can be increased.

The first flush toilet of the present invention having the above configuration can also adopt the following modes. That is, the drainage pipe section may include a plurality of the retaining means, and at least one of the drainage pipe sections may be provided in the protruding pipe section and the drainage pipes other than the protruding pipe section.

In this case, since the siphon action is induced by each of the plurality of retaining means, the suction power and the suction efficiency of the stored water by the siphon action are further increased. Can be

In this case, the stagnation means of the protruding pipe section may be provided near or at the end of the drain pipe.

This makes it possible to more reliably increase the head difference when the siphon action is induced, which is useful for improving the suction power of the stored water and the suction efficiency by the siphon action.

In addition, the retaining means may be a pipe expansion portion having a pipe diameter expanded so as to store passing washing water, or a pipe constriction portion having a small pipe diameter so as to store passing washing water. can do.

In this way, it is possible to reliably store the passing washing water in the pipeline expansion portion or the pipeline restriction portion, which is useful for inducing a siphon effect.

Providing a plurality of these pipeline restriction portions as retention means, that is, having pipeline restriction portions above and below along the pipeline is more useful for inducing siphon action, improving the suction power of the stored water and the suction efficiency. Improvement can be achieved.

In this case, the pipe narrowing portion can be formed by extending a narrow range of the pipe diameter along the pipe direction.

In this way, the washing water that has passed is stored for a long time in the pipeline constriction portion, and then the cleaning water is passed through the pipeline constriction portion. Therefore, it is possible to improve the suction power of the stored water and the suction efficiency by prolonging the induction time of the siphon action.

Further, the trap means may be attached to the toilet body separately from the toilet body forming the ball portion, or the drain pipe portion may be a drain pipe including the protruding pipe portion. The drain section may be provided separately, and the separate drain pipe section may be attached to another portion of the drain pipe to form the drain pipe.

In this way, the shape of the toilet body, which is made of ceramic, does not have a protruding portion from the bottom surface, which is useful for its manufacture and can be handled in installation work, transport work, packing work, etc. It becomes simple. And if the above mounting location is sealed with a seal part and the watertightness of the pipeline is taken, This is preferable because it is possible to prevent the washing water and dirt from leaking out of the pipeline. In particular, if the terminal part of the projecting pipe part separate from the other part of the drainage pipe is located in the existing external drain pipe installed on the floor where the toilet is installed, the existing toilet body will be Can be used as is, which is beneficial in manufacturing.

Further, a first drainage socket of the present invention for solving at least a part of the above-mentioned problems,

A drainage socket connected to the flush toilet for discharging flush water of the flush toilet to an external discharge pipe installed on a toilet installation floor,

A connecting portion connected to the end of a toilet trap line that discharges washing water remaining as non-reserved water to the bowl portion of the flush toilet together with new washing water passed through the ball portion to the outside; ,

A conduit forming portion connected to the connecting portion and forming a continuous discharge conduit with the trap conduit in the toilet;

The pipe forming section forms the discharge pipe up to the inside of the external discharge pipe, and temporarily flushes the washing water passing through the discharge pipe in a portion located inside the external discharge pipe. Has a retention mechanism that induces siphon action by retaining

It is characterized by the following.

If the drainage socket having such a configuration is connected to the end of the trap line in the toilet bowl of the flush toilet, and the flush toilet flush water is discharged to the external discharge pipe, similar to the flush toilet described above, The difference between the flush water surface temporarily retained by the retaining means and the pool water surface of the ball portion can be increased. Therefore, even with this drainage socket, the head difference at the time of siphon action induction can be increased, thereby increasing the water suction force and suction efficiency due to the siphon action. Moreover, since the drain socket only needs to be connected to the existing flush toilet, the existing toilet bowl can be used as it is, which is beneficial in manufacturing.

The drainage socket may be configured such that the conduit forming section has a plurality of the retaining means, or the retaining means may be provided at the end of the discharge conduit or at the end of the discharge conduit. It may be provided in the vicinity thereof.

In this way, the siphon action is induced by the staying means at a plurality of locations and the head difference is increased when the siphon action is induced, which is beneficial for improving the suction power of the stored water and the suction efficiency by the siphon action.

In addition, the connection unit is provided with a unit that is positioned and fixed to the trap duct in the toilet bowl,

The pipe forming section may include a means fixed to the toilet-installed floor in a state where the pipe forming section is positioned with respect to the external discharge pipe.

In this way, the siphon action can be stably induced without being displaced with respect to the toilet or the external discharge pipe even when receiving the force associated with the flow of the flush water when flushing the toilet.

Further, the pipe forming section is formed by decentering a pipe section of the discharge pipe connected to the connection section and a pipe section of the discharge pipe in the external discharge pipe to form the discharge pipe. In this case, even if the trap in the toilet and the external discharge pipe are misaligned, the trap in the toilet and the external discharge pipe can be connected by the discharge pipe of the drainage socket.

Further, the toilet of the present invention for solving at least a part of the above-mentioned problems is:

A toilet equipped with a flush toilet connected to an external drain installed on the toilet floor,

The external discharge pipe is

In the flush toilet, there is provided a retaining means for temporarily retaining the passing flush water to induce a siphon action in a portion of the flush water passing through the flush pipe in the toilet bowl.

It is characterized by the following.

According to the toilet having such a configuration, the siphon action is induced by the stagnation means in the same manner as the flush toilet described above, by the external discharge pipe itself. Therefore, simply connecting the existing flush toilet directly to this external drain pipe or via a drainage socket will effectively induce the siphon action to effectively flush the toilet. Wash water can be drained. In addition, by positioning this retaining means below the floor on which the toilet is installed, it is possible to induce a siphon action with a large head difference, and it is possible to effectively use high water suction power and suction efficiency. Toilet cleaning can be performed. Further, since the flush toilet used may or may not induce the siphon action, the versatility can be further improved.

Further, a first drainage device of the present invention made to solve at least a part of the above-mentioned problems is:

A drain socket having an inlet connected to the outlet of the toilet body and an outlet communicating with a drain pipe connected to the sewer pipe, and having a socket flow path connecting the outlet and the outlet eccentrically; In the flush toilet drainage device with

It is characterized by being provided integrally with the drainage socket and having a throttle unit for temporarily retaining the washing water flowing through the socket flow passage to generate a siphon.

In the first drainage device according to the present invention, the flush water discharged from the toilet body flows from the inlet of the drainage socket to the drainage pipe via the socket flow path and the outlet. At this time, the drainage socket is eccentric between the inflow port and the outflow port, so that the flow of the washing water is bent along the eccentric flow path, so that it is likely to be retained, and the throttle layer is formed by the throttle portion and the cleaning is performed. Induces siphon generation by retaining water. By combining both the eccentric flow path and the restrictor, rather than the configuration in which the washing water is retained only by the restrictor and the eccentric flow path, an excessively bent flow path / a too narrow restrictive flow path It is not necessary to form the waste alone, and there is no clogging of waste.

In addition, the restrictor is formed integrally with the drainage socket, so that it does not slip off or fall off even if it receives the power of the washing water at the time of drainage, and has a desired siphon generation effect. It can be maintained and maintenance is easy. Further, since the squeezing portion is integrally formed with the drainage socket, when the drainage socket is mounted frontward or backward, it is not necessary to position the drainage socket, and the workability is excellent. Such a throttle unit can take various shapes as a position and a shape suitable for siphon generation. For example, the throttle section may be an eccentric throttle flow path with respect to the socket flow path at the position where the throttle section is provided, to achieve a synergistic effect with the flow of the eccentric socket flow path. Can be. In addition, by arranging the throttle portion near the outlet, it is possible to increase the amount of washing water staying upstream of the throttle portion, increase siphon power, and improve the ability to discharge waste. .

In order to further increase the amount of stagnant washing water, the throttle portion extends the socket flow path below the fixed portion of the drain socket to the floor, and a throttle portion is formed at the lower end portion. It is possible to adopt a configuration for disposing.

Since the squeezed portion is formed integrally with the drainage socket, it is not necessary to consider the installation position when installing the flush toilet, and the workability is excellent. In this case, the integral construction means that the flush toilet should be integrated during the construction work and does not impair the workability, and may be formed integrally with the drainage socket or formed separately from the drainage socket. What is necessary is just to be a structure that is integrally assembled and securely fixed and positioned.

In order to improve the effect of siphon generation, the drainage socket is provided with a toilet-side restrictor near the outlet of the flush toilet, and the toilet-side restrictor is arranged eccentrically with the inlet. Various aspects of the invention can be adopted.

A second drainage device of the present invention made to solve at least a part of the above-mentioned problems is:

A toilet connection having an inlet connected to the outlet of the toilet body, a drain connection having an outlet communicating with a drain connected to the drain, and a socket flow path connecting the inlet and the outlet. A washing water retaining means which is separated from the above-mentioned drainage socket, is fixed to the drainage socket, and temporarily retains washing water flowing through the socket flow passage to generate a siphon; It is characterized by having.

In the second drainage device according to the present invention, dirt and washing water discharged from the toilet body flow from the outlet through the socket flow path of the drainage socket, and are discharged from the outlet to the drainage pipe. Wash water retention means is fixed to the drain socket. The washing water retaining means temporarily retains the washing water flowing through the socket flow path to generate a siphon. Since this washing water retaining means is formed separately from the drainage socket, the drainage socket can be made to have a simple structure, and only the optimal design conditions for inducing the siphon are considered. Can be formed.

Therefore, the drainage socket has a simple structure and is easy to manufacture without being restricted by manufacturing conditions such as die cutting when molding by injection molding or the like. Also, the washing water retention means, when fixed to the drainage socket, only needs to consider the optimal conditions for inducing the siphon, and the siphon is generated quickly and with a large force without being restricted by the manufacturing conditions. It can have an effect.

As a preferred embodiment of the washing water retaining means, a configuration in which the flow path area is changed in the direction in which the washing water flows can be adopted. As a mode of changing the flow path area, the flow path area can be configured to be continuously reduced from the upstream side to the downstream side of the socket flow path, and a part of the flow path area is reduced. It can be configured as a throttle unit. As a preferable mode of the throttle portion, the flow channel area can be formed so as to be reduced from the upstream side to the downstream side.

Further, the washing water retaining means may have a configuration in which an expansion channel for increasing the channel area is provided in a part of the upstream side of the throttle section, or a configuration in which a plurality of throttles are provided. As described above, it is easy to obtain an optimum shape for quickly generating a siphon with the washing water flowing through the socket flow path, and thus an excellent water saving effect can be obtained.

Furthermore, when a throttle section is provided in the washing water retaining means, the throttle section is located near the outflow port to store the ball in the bowl of the toilet bowl. The siphon power, which is represented by the difference between the level of the washed water and the outlet, becomes large, and excellent drainage performance can be obtained.

Also, the washing water retaining means is provided with fixing means which is positioned and fixed to the drainage socket, so that the siphon can be stably moved without being displaced with respect to the drainage socket even when receiving the force accompanying the flow of the washing water. Can be generated.

In order to solve at least a part of the problems described above, a second drainage socket according to the present invention includes:

When not flushed, the flush portion is connected to a ball portion for retaining flush water as retained water, and a flush toilet having a drainage channel as a conduit for discharging new flush water supplied to the ball portion to the outside together with the retained water. A drain socket for communicating the drainage channel with a sewage pipe provided outside and for flowing stored water or washing water from the drainage channel to the sewage pipe;

The drainage socket is characterized by comprising two or more members separable in the flowing direction of the stored water or the washing water.

As described above, by forming the drainage socket from two or more members that can be separated in the flowing direction of the stored water or the washing water, the flow path of the stored water or the washing water can be varied depending on the combination of the members. It can be in the form. It is also preferable to provide a variable means for varying the length of the drainage socket in the flowing direction of the stored water or the wash water. In this way, it is possible to connect the toilet and the sewage pipe in a plurality of forms. Therefore, the drainage socket can be shared.

At least two members that can be separated in the flowing direction of the stored water or the wash water are at least a first member that is a member disposed on a floor or a wall surface provided with a sewage pipe; It is composed of a second member to be combined, and is provided with position relation changing means for changing a position relation between the first member and the second member, and the position relation is changed by the position relation changing means. Therefore, it is also desirable to change the length of the drainage socket in the direction of flow of the stored water or washing water. In this way, the floor or wall surface The length of the drainage socket can be changed. Therefore, it is possible to connect toilets with different distances from the floor or wall to the drainage channel with one type of drainage socket, and the workability is further improved.

If at least one of the first member and the second member is provided with a display for displaying information on the length of the drainage socket that has been changed, the drainage socket can be adjusted in length. It is possible to check the extent to which the total length of the bird is changed, and the workability associated with adjustment is further improved. In addition, on the display, the value of the distance from the floor or wall surface where the sewage pipe is installed to the position where the drainage socket is connected to the drainage channel is displayed as information on the variable length of the drainage socket. It may be configured. In this way, it is not necessary to adjust the dimensions while positioning the toilet drainage channel and the drainage socket in order to properly connect the toilet drainage channel and the drainage socket. It is only necessary to measure the distance from the floor or wall surface to the position where the drainage socket is connected to the drainage channel in advance, and to adjust the dimensions of the drainage socket according to this measured value. Therefore, the adjustment work becomes smoother.

A first flow path forming member, which is a member that forms a flow path communicating with at least the end of the drainage channel, at least two members that can be separated in the flow direction of the stored water or the wash water; And a second flow path forming member, which is a member that extends the flow path formed by the first flow path forming member further downstream, and is formed separately from the second flow path forming member. The drainage socket is provided by changing the length of the flow path extended by the second flow path forming member by changing the length of the flow path extended by the second flow path forming member by the flow path changing means. It is also desirable to vary the length of the stored or washed water in the flow direction. By doing so, the flow path length of the drainage socket can be changed to a desired length.

The second flow path forming member is composed of a plurality of members, and the length of the flow path extended by the second flow path forming member can be changed by a combination of the plurality of members. Change the length with a simple task This is preferable in that it can be performed.

The second flow path forming member is provided with a mark indicating a cutting position of the member in advance, and is cut by the second flow path forming member based on the mark, thereby being extended by the second flow path forming member. It is also desirable to adopt a configuration in which the length of the flow path is changed. By adopting such a configuration, it is possible to change the flow path of the drainage socket to a suitable length by cutting, and the cutting operation becomes smooth. Further, the second flow path forming member is a member that can extend the flow path formed by the first flow path forming member below the installation surface of the toilet, and the second flow path forming member is an installation surface of the toilet. The value of the distance extending downward may be displayed in advance near the mark. In this case, the length of the second flow path forming member can be determined so as not to interfere with the sewage pipe below the installation surface of the toilet.

The second flow path forming member is configured to be detachable from a predetermined portion of the drainage socket, and the length of the flow path extended by the second flow path forming member is determined by the mounting position of the second flow path forming member. It may be changed by changing. This makes it possible to easily change the length of the flow channel of the drainage socket.

A first flow path forming member that is a member that forms a flow path that communicates with the end of the drainage path, as two or more members that can be separated in the flow direction of the stored water or the wash water; A second flow path forming member configured as a separate body from the first flow path forming member and extending a flow path formed by the first flow path forming member further downstream; The first flow path forming member includes a first member which is a member disposed on a floor surface or a wall surface provided with the sewage pipe, and a second member combined with the first member,

A flow path changing means for changing a length of a flow path extended by the second flow path forming member; and a positional relation changing means for changing a positional relation between the first member and the second member,

By changing the length of the flow path extended by the second flow path forming member by the flow path changing means, the length of the drainage socket in the flowing direction of the stored water or the washing water can be changed, First by positional relationship changing means It is also appropriate to adopt a configuration in which the length of the drainage socket in the flowing direction of the stored water or the washing water is changed by changing the positional relationship between the member and the second member. According to this configuration, it is possible to freely change both the length of the drainage socket based on the floor or the wall surface and the length of the flow path of the drainage socket. Therefore, the applicable range of the drainage socket can be broadened. For example, even if the type of toilet installed and the condition of the installed sewage pipe differ from one installation site to another, the height of the drain socket from the floor surface and the length of the drain socket flow path can be adjusted. The drainage socket can be suitably mounted.

The second flow path forming member may be provided with a restricting portion that reduces the cross-sectional area of the member from the inlet portion of the member, or the position of the restricting portion may be freely adjusted. Desirable in point. By adjusting the position of the restrictor, the strength of the suction force of the stored water and washing water generated after the occurrence of the siphon action can be adjusted to the desired level in consideration of the type of toilet bowl installed and the condition of the installed sewer pipe. The degree can be determined.

The present invention can also be configured as a flush toilet provided with the above drain socket. Further, the invention may be configured as a flush toilet connected to the above drain socket. For example, in a flush toilet connected to a drainage socket equipped with the above-mentioned distance changing means, the length of the drainage socket with reference to the floor or wall surface changes the floor or wall to the end of the drainage channel. The height of the end of the drainage can be designed and manufactured relatively freely when designing and manufacturing the toilet because the distance between the drains is adjusted. In the flush toilet connected to the drainage socket equipped with the above-mentioned flow path changing means, by changing the length of the drainage socket, the guide route to the sewage pipe for stored water and washing water, Since it is possible to change the stagnation state of the washing water, it is not necessary to provide a complicated structure in the toilet itself to ensure the performance of washing the toilet.

The socket flow path extending member of the present invention includes:

A drainage socket that communicates the end of the toilet drainage channel with an externally provided sewage pipe. A socket flow path extending member that is a member connected to the socket and extends a flow path formed inside the drainage socket further downstream, and has a length that extends the flow path. The gist is that two or more numerical values shown are displayed.

According to the socket flow path extending member having such a configuration, when extending the flow path length of the drainage socket, the length of the flow path can be easily determined. In this case, if different numerical values are displayed as two or more numerical values depending on the type of toilet and the installation condition of the toilet, the flow path in the drainage socket can be extended to a suitable length.

In order to solve at least a part of the problems described above, a third drainage socket according to the present invention includes:

A drainage socket having a socket line connected between the siphon trap and a discharge pipe outside the toilet of the flush toilet having the siphon trap and guiding the washing water passing through the siphon trap to the discharge pipe. And

The socket line has an adjusting means for increasing and adjusting the amount of washing water passing through the socket line at the end of the siphon when the siphon action that has occurred when the siphon trap is full is at the end.

It is characterized by the following.

In the third drainage socket of the present invention having the above-described configuration, the amount of washing water passing through the socket pipe is increased and adjusted at the end of the siphon, so that the area occupied by the washing water in the cross section of the pipe is not reduced. . Therefore, air inflow from the downstream can be suppressed, and the siphon can be maintained accordingly. For this reason, even at the end of the siphon, the suction efficiency of the water in the bowl can be increased by the siphon action, and the reliability of suction and discharge of suspended waste can be improved.

In this case, the end of the siphon is determined by the amount of flush water that flows through it for flushing the toilet, the amount of water stored in the ball section, the diameter of the trapping pipe, etc. It can be determined by the elapsed time. Therefore, When adjusting the amount to be increased, the execution timing may be defined by this elapsed time.

The third drainage socket of the present invention having the above configuration can also adopt the following modes. That is, the adjusting means may have a replenishing means for replenishing the stored washing water to the washing water passing through the socket line at the end of the siphon.

In this way, the siphon is maintained by adjusting the amount of flush water passing through the socket line with the replenishing flush water, improving the suction efficiency of the water in the ball section at the end of the siphon, and consequently the reliability of suction and discharge of suspended solids. Performance can be improved.

In this case, by providing a plurality of replenishing means and replenishing the washing water at a plurality of locations, it is possible to ensure the maintenance of the siphon by the replenishing washing water.

In addition, a siphon inducing mechanism that induces a siphon action by causing a temporary stagnation of passing washing water will be provided in the drainage socket or the siphon trap of the toilet, and a drainage socket replenishing means will be provided near the siphon inducing mechanism. You can also do so. In this way, the washing water can be replenished near the location where the siphon action is induced, so that the maintenance of the siphon can be further assured and the reliability can be improved.

Further, the replenishing means may include a storing means for storing a part of the washing water passing through the socket conduit or the siphon trap before the end time of the siphon.

In this way, make-up flush water can be procured from passing flush water, that is, flush water supplied to the toilet for flushing the toilet. Moreover, there is no need for a special water system for replenishing the washing water. Therefore, the amount of washing water used does not increase, and the configuration can be simplified.

Further, the adjusting means has means for restricting passage of the washing water through the socket line until the end of the siphon, and relaxing the restriction to the washing water at the end of the siphon. Can be.

In this way, the increase in volume can be adjusted by relaxing passage restrictions at the end of the siphon. Therefore, at the end of the siphon, it is possible to maintain the siphon as described above and to improve the suction efficiency of the pooled water. If the restriction on the passage is to be relaxed by an electric drive device, the device may be driven based on the elapsed time from the start of water passage to relax the passage restriction.

Also, the second flush toilet of the present invention,

A flush toilet having a siphon trap,

The siphon trap is

A first descending channel downstream of the bend,

A second downcomer which is connected to the outlet pipe outside the toilet and guides flush water to the outlet pipe;

The second downcomer has an adjusting means for increasing and adjusting the amount of washing water passing through the second downcomer at the end of the siphon when the siphon action generated by filling the siphon trap is full.

It is characterized by the following.

Even in the second flush toilet of the present invention, the amount of flushing water passing through the second downcomer is increased and adjusted at the end of the siphon. Therefore, even with this flush toilet, it is possible to improve the suction efficiency of the water stored in the ball at the end of the siphon and to improve the reliability of sucking / discharging suspended solids by maintaining the siphon.

In this case, the second downcomer is configured separately from the siphon wrap including the first downcomer, and is connected and arranged between the first downcomer and the discharge pipe. It can also be.

In this way, the toilet body made of pottery can be provided with an existing siphon trap, which is beneficial in its manufacture.

Then, the separate second descending pipe section may be the drainage socket described above, or may be replaceable with these drainage sockets.

Further, a flush toilet having a siphon trap may be provided with the above-described drainage socket from the beginning.

In order to solve at least part of the above problems, the third water of the present invention is used. The toilet bowl is

A ball part that receives filth and collects water,

A drain pipe forming a drain passage for discharging the washing water supplied into the ball portion to the outside together with the stored water;

In the siphon type flush toilet with

The drainage pipe is

Retention means for temporarily retaining the washing water flowing in the drain passage to induce a siphon action;

A delay means provided downstream of the retaining means, for delaying the flow rate of the cleaning water when the flow rate or the flow rate of the cleaning water passing through the retaining means is lower than a predetermined value;

It is characterized by having.

In the third flush toilet according to the present invention, dirt, washing water, and the like discharged from the inside of the ball portion flow through the drain passage of the drain pipe and are discharged to the drain pipe connected to the sewer pipe. At this time, the washing water flowing through the drain passage passes through the retention means and the delay means. The stagnation means temporarily stagnates the washing water flowing through the drainage channel to induce a siphon. As a result, cleaning water and dirt in the ball portion are quickly discharged to the outside through the drain passage.

In such a washing process, the washing water that has passed through the staying means goes to the delay means. However, when the flow rate or the flow rate of the washing water is higher than a predetermined value, the washing water flows the washing water as it is, If the flow rate or flow rate of the washing water is lower than a predetermined value, the flow resistance increases and the flow rate of the washing water is reduced. In other words, at the beginning or middle stage of the siphon where the flow rate of the wash water discharged from the pole is large, the wash water quickly discharges contaminants, and at the end of the drainage where the flow rate of the wash water is slow, the wash water is delayed. The time it takes to discharge is longer. Therefore, it is possible to reliably discharge from the ball portion even waste that is discharged late, such as filth floating in the ball portion.

Further, as a preferred embodiment of the third flush toilet of the present invention, Can be configured as a throttle that protrudes from the inner pipe wall of the drainage pipe and reduces the flow passage area of the drainage flow path. The water is trapped in the drainage channel by the constriction, and a siphon is induced. Further, the retaining means can be configured as a peeling means for guiding the washing water flowing along the inner pipe wall of the drain passage away from the inner pipe wall. As a preferable form of such a stripping means, it can be constituted by a stripping projection projecting from the inner pipe wall of the drain passage. The peeling projection changes the flow direction of the washing water flowing in the drainage flow path to quickly induce siphoning.

Further, the delay means includes a delay protrusion projecting from the inner pipe wall of the drain passage, and the delay protrusion passes through the separation protrusion when the flow velocity or the flow rate is lower than a predetermined value. The washing water can be configured to receive the washing water, thereby delaying the washing water.

Further, the delay means may be configured to include a flow direction changing means for changing a direction of the washing water flowing in the drain passage. The direction converted by the flow direction changing means may be any of various directions such as a spiral shape perpendicular to the inner pipe wall and a circumferential direction. Further, as a preferred embodiment of the flow direction changing means, the flow direction changing means can be constituted by a guide portion for flowing the washing water flowing in the drain passage in a spiral shape along the inner pipe wall. Such a guide section can delay the time until the end of re-flow by flowing the washing water in a spiral shape.

The stagnation means and / or the delay means may be provided separately from the drain pipe integrated with the ball portion, or may be configured separately. In a case where the drainage pipe is formed separately, the drainage pipe is provided with a drainage socket formed separately from the ball portion and connecting a drainage outlet of the ball portion and a drainage pipe connected to a sewer pipe. The bird can be configured to include the above-mentioned staying means and peeling means. The drainage socket further includes a socket body that forms a drainage flow path, and the retaining means and the peeling means are configured to be separately mounted on the socket body. Even if the peeling means has a complicated shape, it can be easily molded BRIEF DESCRIPTION OF THE FIGURES

In order to further clarify the configuration and operation of the present invention described above, embodiments of the flush toilet of the present invention will be described below. FIG. 1 is an explanatory view showing a vertical section of a siphon-jet type flush toilet 10 according to an embodiment (first embodiment) of the present invention, and FIG. 2 is an explanatory view showing an upper surface of the flush toilet 10. It is. This siphon-jet type flush toilet 10 ejects water from a jet outlet 22 to be described later as a result of washing, thereby causing a siphon action. Hereinafter, each part of the flush toilet 10 will be described with reference to FIG. 1 and FIG.

As shown in FIG. 1, the flush toilet 10 includes a ball portion 20 for receiving waste. The peripheral wall of the ball portion 20 is in contact with the flush surface 23 even when the flush toilet 10 is not flushed, and with the flush water RW when the flush toilet 10 is not flushed. Not composed of exposed surface 24.

As shown in FIG. 2, the jet port 22 has a jet water supply port 45, which is an inlet of water from which the jet 22 is jetted, and a jet water channel formed so as to be curved inside the toilet. Connected via 4-6. As shown in FIG. 1, the jet port 22 is provided at a position substantially opposite to the discharge port 25 across the concave portion 26, and the energy of the washing water is supplied to the discharge mechanism after the discharge port 25. Is transmitted without waste. Therefore, it is possible to cause the siphon effect early.

A mechanism for supplying water to the ball section 20 (hereinafter referred to as a supply mechanism) and a mechanism for discharging waste in the ball section 20 toward the drain pipe 90 are provided inside the flush toilet 10. (Hereinafter referred to as the discharge mechanism).

First, the supply mechanism will be described. Behind the flush toilet 10 is provided a flush water supply hole 40 for connecting the flush pipe SL of the flush water tank WT. A flush water supply passage 41, which is a flow path of flush water from the flush water tank WT, is provided inside the flush toilet 10 facing the same. The washing water supply channel 41 defines a stagnant portion 41a as a space interposed between the jet water supply channel 46 for jetting the washing water to the ball portion and the lower end of the drainage pipe of the washing water tank WT. I do. The washing water discharged from the drain pipe flows into the stagnant portion 41a during washing, and the inflowing washing water flows into the rim water passage 43 via the jet water supply passage 46 and a branch hole 42 described later. Runs out and acts as a gap without washing water when not washing.

That is, the water stored in the tank (wash water) urged by the free fall is supplied to the wash water supply channel 41. For this reason, the stagnant portion 41 a formed by the washing water supply passage 41 obliquely downwardly formed becomes full after the start of washing, and a part of the washing water is supplied from the branch hole 42 to the rim water supply passage 43. . The washing water supplied to the rim water supply channel 43 is discharged from a drain hole 44 provided on the back side of the rim portion 21 (see FIG. 2). As shown in Fig. 2, on the back side of the rim part 21, a large hole 44 mm with a diameter of 7 mm, a medium hole 44 mm with a diameter of 4 mm, a small hole 44 mm with a diameter of 3 mm, and a substantially rectangular shape There are provided water drainage holes 44 of five different shapes, holes 44d and e. The drain hole 44 is formed at the time of molding the rim portion 21. Of course, a distributor having a drain hole may be mounted on the back side of the rim portion 21. .

In this case, the total open area S _A of the large holes 44a, medium holes 44b, small holes 44c, long holes 44d, and the drain holes 44 of e is the area of each hole. and obtained in decreasing the number of the product, the ratio of the branch hole 4 2 effective passage area (washing water outlet portion open area) S _H for guiding the washing water to the respective holes values (S _H / S _a) is about 1. It is to be 2 and 3. Therefore, the amount of cleaning water supplied to the rim water supply channel 43 is adjusted by the degree of opening of the branch hole 42. In this case, the flow rate can be controlled almost linearly according to the area ratio described above. Also, since the flow ratio that changes according to the area ratio is large, the flow can be controlled very effectively by the branch holes 42. Also, the flow rate can be easily set during design and inspection without any particular trial and error.

Of the above-mentioned water holes, the long holes 44 d and e are provided for imparting swirling components to the cleaning water discharged from the water holes 44. That is, the flush water urged toward the front side of the flush toilet 10 and supplied to the left and right rim water supply channels 43 is distributed according to the opening diameter of the drain hole 44 and the urging force of the flush water. The liquid is discharged from each of the holes 44a to e. At this time, from the long hole 44d formed on the back side of the right rear part 21 near the branch hole 42, water with a large urging force is exposed to the front left slightly exposed surface of the toilet. Discharged toward 24. In addition, from the long hole 44 e formed slightly to the right in front of the flush toilet 10, flush water flowing clockwise through the rim water supply channel 43 is exposed to the flush toilet 10 left rear. A large amount is discharged toward 24. The cleaning water discharged from the long holes 44d and 44e becomes the main stream, and a clockwise turning force is applied to the cleaning water discharged from the water discharging hole 44. This turning force is transmitted to the reservoir RW in the ball portion 20. As a result, The water in the ball portion 20 turns clockwise.

Note that the above is an example of a method of giving a swirl component to the cleaning water discharged from the water discharging hole 44, and of course, another method may be used. For example, the water discharge hole 44 may be formed while giving an angle to the turning direction, or the flow path of the rim water supply path 43 may be formed on one side. Further, in the first embodiment to which the present invention is applied, the rim spout is performed as described above. However, the rim spout may simply be the washing water that is dropped from the rim, and the rim spout is not performed. It may be something.

Further, the washing water that has reached the retaining portion 41a enters a jet water supply hole 45, which is a hole provided in a side wall of the retaining portion 41a. With this approach, flush water is supplied to the jet water supply channel 46. The washing water supplied to the jet water supply channel 46 is jetted from the jet outlet 22. When the stagnant portion 41a is replaced with the washing water, the washing water is guided from the branch hole 42 to the rim water supply passage 43, and the washing water is discharged from the water discharging hole 44 of the rim.

Discharge amount from the water out hole 4 4 and allocation of the ejection amount from the absolute Bok ejection holes 2 2 by adjusting the branch hole 4 2 effective passage area (washing water outlet portion open area) S _H , It is possible to set arbitrarily.

Next, the discharge mechanism will be described. As shown in Fig. 1, at the end of the discharge port 25 formed in the depth of the recess 26 as a waste pool, a water or dirt flow path (trap) diagonally upward from the discharge port 25 The connecting path 31 and the connecting path 31 extend in the bending direction of the connecting path 31 and then bend in the horizontal direction. The ascending path 32 and the descending path 33 that bends downward from the horizontal direction are formed. Have been. In this case, the connection path 31 and the ascending path 32 are the ascending pipeline according to the present invention.

The descending path 33 has, at its distal end, an extended portion 33 a having an enlarged pipe diameter and an end narrowed portion 33 b having an opening area smaller than that of the extended portion. Therefore, the descending passage 33 temporarily retains the washing water passing through the extension portion 33a and the end narrowing portion 33b, so that the descending passage 33 itself induces a siphon action. This descending channel 33 is made of resin drainage at its end. Through the socket 70, it is connected to the drain pipe 90 that is set up from the toilet floor FL at the place where the toilet is installed.

The distance from the rear end of the flush toilet 10 shown in Fig. 1 to the center of the drain pipe 90 is set to 180 mm, and the distance from the rear end of the flush toilet WT assembled to the flush toilet 10 is set. The distance to the center of the drain pipe 90 is assumed to be 190 mm. In other words, if the drain pipe 90 is set up at a position 200 mm from the wall of the toilet room, the set of the flush toilet 10 and the washing water tank WT can be moved to the back of the washing water tank WT. It can be installed with a clearance of 10 mm from the toilet room wall. Thus, if the flush toilet 10 and the flush water tank WT are set, the drain pipe 90 can be provided at a position close to the wall on the building side. As a result, the distance from the drain pipe 90 to the pipe space is shortened, and smooth conveyance of waste can be ensured. Of course, if the clearance with the wall of the toilet room is not taken into consideration, the above distance can be set to a value of 200 mm or less.

These flow channels are formed integrally with the ceramic flush toilet 10 by shaping the flow channel shape into a gypsum mold or a resin mold, but they are formed by a separate member from the flush toilet 10. It is also possible to form a path. For example, all or some of these flow paths may be formed of another member such as a resin and connected to the discharge port 25.

The drain socket 70 is located on the toilet floor FL and is fixed to the toilet floor with a bolt or the like. The socket body 71 is located inside the drain pipe 90 and the drain socket 72 is located inside the drain pipe 90. And The socket body 71 has a descending passage fitting portion 71a into which an end of the descending passage 33 enters at an upper end thereof, and has a first water passage 73 below the fitting portion. The diameter of the first water passage 73 is substantially the same as the diameter of the descending passage 33 described above. Further, the socket body 71 has a drain pipe fitting part 74 into which the upper end of the drain pipe 90 enters from below. The drain pipe fitting portion 74 positions the drain socket 70 with respect to the drain pipe 90 by fitting the drain pipe 90. Soshi Since the end of the first water pipe 73 is located below the upper end of the drain pipe 90, the washing water that has passed through the first water pipe 73 leaks from the upper end of the drain pipe 90. It is confused.

The drain pipe socket portion 72 has a tapered first cylindrical portion 72 having a flange portion 72a at the upper end thereof, and a straight second cylindrical portion 72c at the distal end of the cylindrical portion. As described above, since the first cylindrical portion 72 b is tapered, the socket portion 72 in the drainage pipe has a flange portion 72 a even if the pipe diameter of the drainage pipe 90 is slightly larger or smaller. The drain pipe 90 is fitted and mounted so as to be in contact with the upper end of the drain pipe 90 or slightly away from the upper end. In this case, the socket portion 72 in the drain pipe has a sheet-like sealing material such as a rubber sheet on the outer peripheral portion near the upper end of the first cylindrical portion 72 b and the back surface of the flange portion 72 a. This is preferable because the pipe can be made watertight at the upper end opening of the drain pipe 90.

The socket portion 72 in the drainage pipe attached to the drainage pipe 90 in this manner is located below the first water pipe 73 and has a socket extension having a pipe diameter larger than that of the pipe.

75, and a throttle pipe section 76 having substantially the same diameter as the first water supply pipe 73 below this expansion section, and this socket expansion section 75 and throttle pipe section 76 are formed. Is located below the floor F of the toilet and is used as a drain for washing water. And, even in the socket extension section 75 and the throttle pipe section 76 which are lower than the toilet floor FL, the cleaning water passing through these sections is temporarily retained to induce a siphon action. Let it.

The socket body 71 of the drainage socket 70 and the socket portion 72 in the drainage pipe are both resin molded products, and are separate from the flush toilet 10 in detail, and separate from the downcomer route 33. However, it may be integrated with this descending route 3 3. As described above, when integrating with the descending path 33, a pipe such as the first water pipe 73 is connected to the expanded section 33a with the end narrowed section 33b interposed therebetween, and further below it. In this case, a pipeline expansion section such as a socket expansion section 75 and a pipeline such as a throttle pipeline section 76 may be connected by a forming material of the descending channel 33. The socket body 71 of the drain socket 70 and the socket portion 72 in the drain pipe are molded with resin. The product can be made of the same vinyl chloride resin as the drain pipe 90, as well as ABS resin, PP (polypropylene), PE (polyethylene), PPS (polyphenylene sulfide), MA (acrylic), and POM (polyacetal). ) Can be used.

In this case, since the above-mentioned socket portion 72 in the drain pipe can be formed separately from the socket body portion 71, it can be attached to the drain pipe 90 alone. In this way, the drain pipe 90 itself can induce the above-mentioned siphon action.

In a state where the above-mentioned drainage socket 70 is mounted, the flush toilet 10 forms a descending pipe for discharging flush water so that its end projects downward from the toilet floor FL. The part protruding from the toilet floor FL will have an expansion part and a throttle part for inducing the siphon action.

As shown in FIG. 1, in the flush toilet 10 before the washing operation, the accumulated water RW is stored at the height of the normal water level line WL in the connection path 31, the ascending path 32, and the ball portion 20. . The spilled water RW prevents the backflow of odor and the invasion of pests from the drainage mechanism to the ball portion 20. In the first embodiment, while reducing the amount of the pool water RW, a large pool surface with a width of 18.5 mm and a depth of 22.5 mm was secured. It prevents dirt sticking and odor emission from the exposed surface 24.

The pooled water RW contains the water collected inside the ball portion 20 up to the discharge port 25 (hereinafter, this water is referred to as ball-ported water or sealed water) and the connection path 3 after the discharge port 25. 1 and the ascending channel 32 (hereinafter, this water is referred to as accumulated water in the channel), and the water that accumulates in the lower part of the retaining portion 41 a of the flush toilet〗 0 and the jet water supply channel 46 (hereinafter, this water). (Water is referred to as zeta water). As shown in Fig. 1, the accumulated water in the channel is one of the sewage channels consisting of the connecting channel 31, the ascending channel 32, and the descending channel 33, from the connecting channel 31 to the ascending channel 32. Only accumulates in places. The term “sewage” refers to water that is polluted by the mixing of stool, urine, and other filth and paper. Normally, the height of the water line WL is determined by the height of the weir 34, which is the highest position below the inner wall of the ascending path 32. Therefore, as shown in FIG. 1, since the lower part of the retaining portion 41 a of the flush toilet 10, the jet water supply hole 45 and the jet water supply channel 46 are below the weir 34, the flush toilet 1 In the stationary state of 0, the bottom of the stagnation section 41 a and the jet water supply channel 46 are filled with jet water at the above-mentioned water level. If the height of the weirs 34 is reduced, the water level of the stored water RW is also lowered, and the amounts of the water in the ball portion, the water in the flow path, and the water in the jet are also reduced.

A mechanism for discharging sewage and waste by the drainage mechanism configured as described above will be described. When the wash water is discharged from the wash water tank WT, the discharged wash water first flows into the retaining section 41a, and the position energy is used as kinetic energy to discharge the jet water in the jet water supply path 46 as a ball. Pour into bowl 20 pool water (sealing water). As a result, jetting of the washing water toward the trap from the jet outlet 22 is started, and thereafter, while the discharge of the washing water is continued, the discharged washing water itself is jetted with the above energy. It is continuously ejected from the orifice 22. Since the stagnation portion 41a is replaced with the discharge cleaning water at an early stage of the progress of the jetting operation, the discharge cleaning water is jetted from the discharge hole 44 through the branch hole 42 after the replacement is completed.

When the washing water is ejected to the ball portion 20 in this way, the water level of the ascending path 32 rises, and the bent portion from the ascending path 32 to the descending path 33 (hereinafter referred to as a bent portion) is full. become. As a result, the washing water passes through the descending path 33, and when passing through, the extension part 33a at the end of the descending path and the socket extension part 75 below the toilet floor FL are squeezed. Temporary storage of the washing water in the pipe section 76 occurs, and a pressure difference is generated between the washing water and the pooled water in the ball section 20 to generate a downward pulling force. With this drawing force, the washing water (dirty water) filled in the ascending path 32 and the connecting path 31 and the cleaning water (dirty water) in the ball are led to the drain pipe 90 together with the dirt. Thus, a siphon effect is induced. In the siphon-jet type flush toilet 10 of the first embodiment configured as described above, the siphon action is induced by not only the extension part 3 3a at the end of the descending path 33 but also the end narrowing part 33b at the end. It also occurs in the socket extension 75 and the squeeze pipe 76, which are lower than the toilet floor FL by the drainage socket 70. Therefore, there are the following advantages.

First, since the siphon action is induced at two points, the end of the descending route 33 and the drainage socket 70, the suction power and the suction efficiency of the ball portion 20 due to the siphon action can be further improved. .

In addition, the drain extension socket 75 formed by the drainage socket 70 to induce the siphon action and the throttle pipe section 76 are positioned below the toilet floor FL to increase the head difference when the siphon action is induced. did. Therefore, the suction power and the suction efficiency of the stored water by the siphon action can be further improved. In addition, since the throttle pipe section 76 is provided at the end of the pipe for draining the washing water and the socket expansion section 75 is provided near the end of the pipe, the head difference at the time of the siphon action induction is more reliably increased. Therefore, it is possible to effectively improve the water suction power and the suction efficiency.

The portions that induce the siphon action by restricting the pipeline are defined as the downcomer 33, the terminal restrictor 3 3b at the end, and the restrictor conduit 76 of the drainage socket 70. Along the top and bottom. Therefore, it is possible to ensure the temporary storage of the washing water passing therethrough, and to more effectively induce the siphon action to improve the suction power of the stored water and the suction efficiency. Then, the restricting pipe section 76 of the drainage socket 70 is extended along the pipe direction by a certain length (about 4 O mm), so that the passage of the washing water is prevented and the storage time is reduced. extend. For this reason, the siphon effect induction time can be lengthened, and effective improvement of the suction power and the suction efficiency can be achieved.

In addition, a drainage socket 70 was used separately from the flush toilet 10 when installing the siphon action induction section below the toilet floor FL. For this reason, the flush toilet 10 is made of ceramic as before, and the protrusion from the bottom is made. Since it can be made into a shape that does not have it, there is no need for new production of a production die, etc., which is beneficial in production. In addition, it will be easier to handle flush toilets during installation work, transport work, and packing work. Drainage socket 7

Since the siphoning action inducing section can be provided below the floor FL of the toilet by means of 0, the existing flushing toilet 10 can be used as it is, which is advantageous in manufacturing.

Furthermore, when the siphon action inducing section is provided below the toilet floor FL by the drain socket 70, the socket section 72 inside the drain pipe separate from the socket body section 71 of the drain socket 70 is used. Attach it to 90. Therefore, since it is not necessary to re-install the drain pipe itself, the flush toilet 10 of the first embodiment can be easily installed when the toilet is remodeled.

Next, a modified example will be described. In the above-described first embodiment, the downcomer 33 itself is described as a flush toilet in which the siphon action is induced by the extension portion 33a at the end thereof. It can also be applied to flush toilets that do not have a siphon induction section on the road. FIG. 3 is an explanatory view showing a modified example applied to a flush toilet having a descending passage 33 formed as a simple pipeline. Even in this modified example, the drainage socket 70 can induce a siphon effect with a large head difference between the socket extension portion 75 and the throttle line portion 76 at a position lower than the floor FL of the tray. Thus, it is possible to effectively improve the suction power of the stored water and the suction efficiency. In this modified example, if the diameter of the first water pipe 73 formed by the socket main body 71 is smaller than the diameter of the lower water pipe 33 above the first water pipe 73, the first water pipe 73 will have a siphon action. Can be a throttle part for triggering. Therefore, this is preferable because siphon action can be induced at a plurality of locations.

FIG. 4 is a cross-sectional view of a drainage socket 70 of a modified example in which the socket body 71 and the socket 72 in the drainage pipe are integrated. Even in the drainage socket 70 of this modification, the socket main body 71 forms a first water passage pipe 73 below the descending path 33, and the socket part 72 in the drainage pipe has Following the 1 water pipe 73, the socket expansion section 75 with the expanded pipe diameter and the first A throttle pipe section 76 having substantially the same diameter as the water pipe 73 is formed. In the drainage socket 70 of this modified example, the socket extension part 75 and the throttle pipe part 76 are used as siphon action inducing parts located below the toilet floor FL. In this modification, the socket portion 72 in the drain pipe is a blow-molded product in which the middle of the pipe expands, and the screw portion provided on the inner periphery of the upper end opening of the socket portion 72 of the socket body 71 First water passage 7 3 Screwed to lower end. According to the drainage socket 70 of this modified example, as described above, the siphon action can be induced with a large head difference, so that it is possible to effectively improve the water suction power and the suction efficiency. In this modified example, the drainage socket 70 can be handled as an integral product, so that the installation work on the drainage pipe 90 can be simplified.

FIG. 5 is a cross-sectional view of a main part of a drainage socket 70 of another modification. As shown in the figure, in this modified example, a seal member 77 is provided in the descending passage fitting portion 71a into which the end of the descending passage 33 enters. The sealing member 77 is made of an elastic material such as rubber, and when the descending passage 33 is inserted, the tapered portion on the inner peripheral side is expanded to closely contact the outer periphery of the descending passage 33. And seal. Therefore, according to this modified example, the watertightness of the pipeline is achieved at the lower end of the descending path, so that it is possible to prevent the washing water and dirt from leaking out of the pipeline. Further, the drainage socket 70 can be positioned and fixed to the descending path 33 via the sealing material 77.

FIG. 6 is a cross-sectional view of a main part of a drainage socket 10 of another modification. In this modification, the drain pipe 90 is installed without rising from the toilet floor FL. In this modified example, as shown in the figure, a disc-shaped sealing material 78 made of rubber or the like is disposed on the front and back surfaces of the flange portion 72 a of the socket portion 72 in the drainage pipe, Attach the socket section 72 to the drain pipe 90. Then, a sealing wall 73a extending downward so as to surround the first water passage 73 of the socket body 71 on the outside thereof abuts on the sealing material 78 on the upper surface of the flange 72a, and the seal wall 78a is formed. The socket body 7 1 is fixed to the toilet floor FL so that the part is sealed. You. According to this modification, even when the drain pipe 90 is installed without rising from the toilet floor FL, the siphon action induction part is formed below the toilet floor FL to form The effect can be achieved. In addition, since the drain pipe 90 is sealed with the sealing member 78 to make the pipe watertight, it is possible to prevent the washing water and dirt from leaking out of the pipe.

The first embodiment described above can be modified as follows. For example, in the first embodiment, the low tank type tank connected to the toilet is used as the flush water tank, but a tank other than the low tank type tank, for example, the toilet wall is connected to the toilet through a flush pipe and is connected to the toilet. A tank with a corner or a flat type, which is installed at a location such as the above, may be used. In this case, the washing water tank can be installed at a high position to make it a high tank.

Further, the case where the present invention is applied to a siphon-jet type flush toilet 10 or a siphon toilet has been described as an example, but it can be understood as an invention in which the above-mentioned toilet and other devices and members are combined. For example, the present invention can be applied to a flush-type flush flush toilet of a flushing type in which the wastewater discharged into the bowl portion of the toilet and the wastewater contaminated by the waste are flushed using the flushing water supplied to the toilet. In addition, a sanitary washing device combined with a functional toilet seat that realizes various functions such as local washing and heating, a cabinet for storage, a toilet kit device combined with a hand washing device, a wall material, a floor material, and a structural member in a toilet room. A system tray device combining ceiling materials and the like can be considered.

Although the drainage socket 70 has been described in connection with the case where the downcomer 33 and the drainage pipe 90 face each other, even when the position of the downcomer 33 and the drainage pipe 90 are misaligned, Applicable. FIG. 7 is an explanatory diagram for describing a drainage socket 70 of a modified example applied to such a case. The drainage socket 70 of this modified example includes a descending passage fitting part 71 a into which the end of the descending passage 33 enters, a first water passage pipe 73 located in the drainage pipe 90, and a socket extension part 7. 5 and the throttle conduit 76 are provided eccentrically, and the socket main body 71 is bent or bent in accordance with the above-mentioned positional deviation. In this way, even if the position of the downcomer 33 and the drainage pipe 90 are misaligned, the downcomer 33 is connected to the drainage pipe 90 via the drainage socket 70 and the drainage socket is connected. A siphon effect can be induced in the first water passage 73, the socket extension 75 and the throttle line 76.

Further, the present invention is applicable even when the drain pipe 90 is a lead pipe. FIG. 8 is an exploded perspective view of a drain socket connecting portion applied to such a drain pipe 90 made of a lead pipe, FIG. 9 is a cross-sectional view of the drain socket connecting portion, and FIG. 10 is a plan view thereof.

As shown in these drawings, in the case of the drain pipe 90 made of lead pipe, the metal flange 17 1 is fixed to the toilet floor with the fixing screw 17 2 with the drain pipe 90 projecting upward. Fix to surface FL. In this case, it is sufficient that the drain pipe 90 protrudes about 15 mm from the toilet floor FL. Next, the opening of the drain pipe 90 is expanded in a tapered shape so as to follow the tapered slope 1 79 of the metal flange 17 1. Then, a tapered P-seal gasket 173 is arranged so as to overlap the tapered expansion opening of the drainage pipe 90, and the fixing bolt 175 is fixed while the gasket is sandwiched by the adapter 174. And fix it to the metal flange 17 1. The drainage socket 70 described above is fixed to the upper end cylindrical portion of the adapter 174 fixed in this manner. According to this modification, even in the case of a drain pipe 90 made of a lead pipe, the downcomer 33 is connected to the drain pipe 90 through the drain socket 70, and the first water pipe of the drain socket is connected. 73, a siphon effect can be induced in the socket extension 75 and the throttle line 76.

Next, other embodiments will be sequentially described.

The drain pipe PD has an outer diameter D 2 and a wall thickness t 2. Here, the outer diameter and thickness are D 1 <D 2 and t 1 <t 2. FIG. 13 is an explanatory diagram illustrating a state in which a drain pipe P is provided on the floor surface FL of the toilet room. In Fig. 13, the drainage pipe P (PA) is not at the same distance from the front wall WF of the toilet room, but at distances L1 (120 mm) and L2 (200 mm) depending on the building and other conditions. Located in different locations. The drainage socket 120 accommodates all four different drainage pipes P and two different rough-in dimensions. Hereinafter, the drainage socket 120 will be described in detail.

Fig. 14 is a cross-sectional view showing the drainage socket 120 of Fig. 11 in an enlarged manner. Fig. 15 is a cross-sectional view of the drainage socket 120 cut in a direction perpendicular to the longitudinal direction of the toilet body 1 1 1. It is. In Figs. 14 and 15, the drainage socket 1

Reference numeral 20 denotes a toilet connecting section 121, a connecting pipe section 123, a drain pipe connecting section 124, a socket fixing section 128 (see Fig. 17), and a toilet fixing section 1 29 (Fig. 15) is integrally molded with resin.

The toilet connection section 121 includes a sealing member 122 for sealing between the trap drain pipe 111b and the outlet side. By inserting the outlet side of the trap drain pipe 1 1 1 b into the opening 1 2 2 a of the sealing member 1 2 2, the gap between them is sealed and the trap drain pipe 1 1 1 b is discharged. 1 1 6 is connected to the inlet 1 2 1 a.

In addition, the toilet connection section 121 and the connecting pipe section 123 are provided with a socket flow path 1, which connects the above-mentioned inlet port 121 a and the outlet port 124 a eccentrically.

1 2 3b is formed. The socket channel 1 2 3a is located at this step 1 2 When the washing water hits 3b, turbulence is generated and the washing water stays.

The drain pipe connecting portion 124 has an outlet cylindrical portion 125 having an outlet 124a, a first cylindrical connecting portion 126 and a second cylindrical portion concentrically with the outlet 124a. Connection part 127. The outflow cylinder part 125 is inserted into the drain pipe P connected to the sewer pipe to prevent the washing water from leaking to the outside.

In the middle of the outflow cylinder portion 125, a throttle portion 124b is formed as a throttle portion. The flow passage of the constricted portion 124b is formed so as to have a concentrically narrow flow passage area with the socket flow passage 123a of the outflow tube portion 125. The siphon is generated quickly by rapidly reducing the flow passage area of No. 5, and is formed integrally with the outflow cylinder part 125 by injection molding.

FIG. 16 is an enlarged cross-sectional view showing the vicinity of the drain pipe connection portion 124. In FIG. 16, the first cylindrical connecting portion 1 26 and the second cylindrical connecting portion 127 are provided with drain pipes P having different outer diameters D 1 and D 2 (see FIG. 12). A cylindrical body for connection, a gap d1 between the outflow cylindrical portion 125 and the first cylindrical connecting portion 126, and the first cylindrical connecting portion 126 and the second cylindrical connecting portion 1 The gap d2 with 27 is formed to be larger than the thickness t2 of the drainage pipe P, between which drainage pipes P having different thicknesses t1 and t2 can be inserted. The connection surface of the first cylindrical connection portion 1 26 or the second cylindrical connection portion 127 is formed by fitting the drain pipe P with an adhesive between the outer peripheral surface of the drain pipe P and the outer peripheral surface of the drain pipe P. It is to join.

In order to facilitate such a bonding operation, the following configuration is adopted. That is, the first tubular connecting portion 126 is formed to be longer downward than the outflow tubular portion 125, and the second tubular connecting portion 127 is formed to be the first tubular connecting portion 126. It is formed longer downward. As a result, the tubular portion located on the inner peripheral side is shorter than the tubular portion located on the outer peripheral side, so that the connecting surface of the first tubular connecting portion 126 and the connecting surface of the second tubular connecting portion 127 are formed. Apply adhesive In doing so, a work space for bonding is secured so that the inner tube does not interfere, facilitating the bonding work.

FIG. 17 is a side view of the drainage socket 120, and FIG. 18 is a bottom view of the drainage socket 120. As shown in FIGS. 17 and 18, a socket fixing portion 128 is formed at the bottom of the drainage socket 120. The socket fixing portion 128 is a portion for fixing the drainage socket 120 to the floor surface FL, and the socket fixing leg 122 is provided on the outer peripheral side of the second cylindrical connecting portion 127. It is provided with a flat plate part 128a that extends in the horizontal direction from the socket fixing leg 128d in a substantially rectangular shape. The drainage socket 120 is fixed to the floor surface FL by being screwed with the screw 128c through b.

Referring back to FIG. 15, the toilet bowl 120 is provided with toilet bowl fixing portions 12 9 and 12 9 on the side thereof. Toilet fixing parts 1 229 and 1 229 are parts for fixing the toilet body 111 at the top of the drainage socket 120, and screw fixing parts 1 229a and 129a on the upper surface. Are provided. The screw fixing portions 1229a and 1229a are formed symmetrically with respect to the longitudinal direction of the toilet body 1 11 and symmetrically with respect to the direction perpendicular to the longitudinal direction. In other words, even when the drain socket 120 is turned back and forth, the screw fixing sections 1 229 a and 1 229 a are not connected to the socket fixing section 1 1 1 d of the toilet body 1 1 1. They are formed so as to be arranged at the same position.

Next, the installation work of the flush toilet 110 will be described. First, when the drain pipe PA shown in FIG. 12 (A) is installed at a distance L1 (120 mm) as shown in FIG. 13 (A), the drain socket 120 is removed. The operation of installing the toilet body 1 1 1 will be described.

FIG. 19 is an explanatory diagram for explaining the work of installing the drainage socket 120. First, the drain pipe P is cut from the floor at a predetermined height (for example, 60 mm). After that, check before and after the drainage socket 120, and align the center line of the drainage socket 120 with the centerline where the toilet body 1 11 is to be installed. Insert the cylindrical connection 1 2 6 into the drain pipe P, and Temporarily position drainage socket 120 as shown at 20. At this time, the drainage socket 120 is tentatively arranged so that the toilet connection portion 12〗 faces forward. Next, make a pilot hole in the floor surface FL using the screw hole 1 28 b of the socket fixing section 128 (see Figs. 17 and 18).

Next, the drainage socket 120 is separated from the floor surface FL, and an adhesive is applied to the connection surface of the first cylindrical connection portion 126 of the drainage socket 120. Apply adhesive to the surface. Then, the first cylindrical connecting portion 126 is fitted to the drain pipe P so that the drain socket 120 is returned to the position where the temporary positioning is performed. As a result, as shown in FIG. 14, the first tubular connecting portion 126 is connected to the drain pipe P via an adhesive. In this state, the drainage socket 120 is fixed to the floor surface FL by screwing it into the screw holes 1 28 b at four places of the socket fixing portion 128. Next, as shown in Fig. 15, align the outlet 1 1 6 of the toilet body 1 1 1 with the inlet 1 2 1 a of the toilet connection 1 2 1 of the drain socket 1 20. Install the toilet body 1 1 1 on the floor FL. As a result, the outlet 1 16 is inserted into the inlet 1 2 a of the toilet connecting section 1 21, and is sealed by the seal member 1 2 2. By inserting screws 12 9 b and 12 9 b into the socket-side fixing portion 11 d of the toilet body 11 and the toilet fixing portions 12 9 and 12 29, respectively, the toilet body 11 Fix 1 to drain socket 1 20.

Next, as shown in Fig. 13 (B), the drainage socket 120 is connected when the drainage pipe PA is installed at a distance L2 (200 mm) from the front wall WF of the toilet room. The operation will be described. This work is the same as the work described above, except that the installation direction of the drainage socket 120 is different between front and rear. That is, as shown in FIG. 21, the drainage socket 120 is arranged such that the toilet connection portion 121 faces the front wall WF. As a result, even if the position of the drain pipe P is different, the distance from the front wall WF to the inflow port 121 a can be increased by simply changing the position of the drain socket 120 (L 1 + L 2 ) Install the toilet body 1 1 1 at the same position indicated by 2. Can be.

Therefore, according to the above-described embodiment, even when the drain pipes P are arranged at different positions, the same orientation of the toilet room can be achieved by changing the mounting direction of the drain socket 120. The toilet body 1 1 1 can be installed at the position. Therefore, it is not necessary to use a different drain socket 120 according to the location of the drain pipe P.

Next, the installation work of the toilet body 111 when the outer diameter of the drain pipe P is made different is performed as follows. That is, as shown in FIGS. 12 (C) and 12 (D), when the drain pipe PC or the drain pipe PD having the outer diameter D2 is used, the drain socket 120 shown in FIG. 14 is used. The same operation as described above is performed except for the operation of applying an adhesive to the connection surface of the second cylindrical connection portion 127 of the above. In other words, the drainage sockets 120 are the same, and the surface to which the adhesive is applied may be changed according to the outer diameter of the drainage pipes PC and PD. In addition, as shown in FIG. 16, the gap d 1 between the outflow cylindrical portion 125 and the first cylindrical connecting portion 126 and the first cylindrical connecting portion 126 and the second cylindrical connecting portion Since the gap d2 with 27 is larger than the thickness t2 of the drain pipes PB and PD, the thick drain pipes P with these thicknesses t2 must be connected by the same drain socket 120. Can be.

Therefore, the drainage socket 120 differs only in its orientation or the surface to which the adhesive is applied, as appropriate, and the outside diameter, wall thickness and arrangement position are different under the same construction conditions. It is compatible with various drainage pipes P shown in Fig. 13 and has excellent workability.

In addition, the drainage socket 120 has the following configuration to quickly generate siphons. FIG. 22 is an enlarged sectional view showing the vicinity of the drainage socket 120.

The drainage socket 120 has a stepped portion 123b between the toilet connecting portion 121 and the connecting pipe portion 123, and the washing water flows on the stepped portion 123b and flows there. By changing the direction, a water film is formed, and a delay effect of the washing water is obtained, and siphon generation is induced. This step 1 2 3 b The cut channel 123a is formed by eccentricizing the inlet 122a and the outlet 124a.

A throttle 124 b is formed at the outlet 124 a of the drainage socket 120. The throttle section 124b increases the delay effect of the washing water near the outlet 124a. Such a constricted portion 124b can more quickly and reliably generate a siphon due to a synergistic effect with the stepped portion 123b.

Since the narrowed portion 124b is formed integrally with the drainage socket〗 20 by injection molding with resin, there is no need to assemble it with the drainage pipe P as described in the related art, and mounting workability is improved. It does not disturb the generation of siphons due to water pressure during drainage.

Further, the above-described embodiment has the following other functions and effects.

(1) Since the drainage socket 120 is screwed to the floor surface FL at the socket fixing part 128, the drainage pipe P and the drainage socket 120 can be securely joined.

(2) The drain pipe P is joined to the first cylindrical connection part 126 or the second cylindrical connection part 127 of the drain socket 120 via an adhesive, so that both are securely connected. To prevent water leakage at the time of backflow.

(3) The toilet body 1 1 1 is screwed and fixed at the toilet fixing part 1 29, so that both can be securely fixed and the toilet body 1

Since the fixed position behind 11 is located above the floor surface FL, cleaning becomes easy.

(4) Since the outflow cylinder 125 is provided on the innermost side of the drainage socket 120, all the washing water is surely guided to the drainage pipe P. No water leaks from the connection with the 1 cylindrical connection 1 2 6 or the 2nd cylindrical connection 1 2 7.

FIG. 23 is a sectional view showing a drain socket 120B according to the third embodiment. The drain socket 120 B in Fig. 23 is the toilet connection 1 2 1 B And a connection pipe section 123B connecting the outlet cylinder section 125B with an inclined socket flow path 123Ba. The socket flow path 123Ba has a flow path that flows along the inclined surface 123Bb of the inner wall of the connecting pipe part 123B. Also, a constricted portion 124bb is formed so as to be continuous with the lower end of the inclined surface 123bb. The constricted portion 1 2 4 bb includes a constricted recirculation channel 1 2 4 Bc with respect to the center axis of a certain diameter of the constricted portion 1 2 4 bb. The plane with the lower end of the inclined surface 1 2 3 B b is defined as a staying surface 1 2 4 B d.

According to the drainage socket 120B, the washing water flowing into the toilet connection portion 121B flows along the inclined surface 123Bb of the connecting pipe portion 123B, and the retention surface. After being turned in the horizontal direction by 1 2 4 Bd, it flows out of the throttle channel 1 2 4 Bc. Therefore, in the drainage socket 120 B, the positional relationship between the inclined surface 123 Bb of the connecting pipe part 123 B and the restriction flow path 124 B c of the restriction part 124 B is Since the direction of the washing water is changed to the horizontal direction, it is possible to reliably generate a water film in the vicinity of the throttle portion 124bb and to induce the siphon at an early stage.

FIG. 24 is a cross-sectional view showing a drainage socket 120C according to the fourth embodiment. The drainage socket 120 C in FIG. 24 is located at the lower end of the outlet cylinder portion 125 C, that is, the position of the throttle portion 124 Cb is smaller than that of the drainage socket 120 B in FIG. It is provided near the outlet 1 24 a and features a structure in which the position of the throttle channel 1 24 C c of the throttle section 124 C b is eccentric to the inclined surface 123 C b side. are doing.

That is, the flow path between the lower end of the inclined surface 123 Cb and the upstream side of the constricted portion 124 Cb is formed as long as the height H. In addition, in the restriction channel 1 24 Cc of the restriction section 124 Cb, the washing water flowing along the inclined surface 123 Cb was provided on the side opposite to the inclined surface 123 Cb side. It is formed eccentrically so as to hit the staying surface 1 2 4 C d. According to the drainage socket 120 C, the washing water flowing along the inclined surface 123 Cb of the drain pipe connection part 124 C is retained in the restriction part 124 Cb. C d Siphons are generated between the lower end of 1 2 3 Cb and the narrowed section 1 2 4 Cb, causing siphoning. By providing the throttle portion 124 Cb at an eccentric position in this way, it is possible to quickly generate a siphon according to the washing water flowing along the inclined surface 123 Cb. In addition, since the washing water accumulates in the long flow path (height H) between the inclined surface 123 Cb and the constriction part 124 Cb, the washing water that accumulates on the bowl surface of the toilet body is not affected by the washing water. The water level difference increases, and the siphoner can be enlarged.

FIG. 25 is a sectional view showing a drainage socket 120D according to the fifth embodiment. The drainage socket 120D in Fig. 25 has an outlet cylinder 125D extending below the socket fixing leg 122D, and the lower end of the outlet cylinder 125D. It is characterized by a configuration in which a throttle section 124 Db is provided. Here, Fig. 25 shows a case where a flush toilet is installed in the toilet room on the second floor of the multi-story floor. The drain socket 122D is fixed to the floor surface FL with socket fixing legs 128D.

Are connected by The drain pipe P is connected to a horizontal branch drain pipe PS bent at a substantially right angle.

Further, a throttle portion 124Db is attached to the lower end of the drainage socket 120D. FIG. 26 is a cross-sectional view showing, in an enlarged manner, the vicinity of the narrowed portion 124Db. The throttle section 124Db is detachably attached to the lower end of the outflow cylinder section 125D. That is, the throttle unit 124 Db includes a throttle plate 124 Dd having a throttle channel 124 Dc. A female screw 1 24 D e is formed on the outer periphery of the diaphragm plate 1 2 4 D d, and is screwed into a male screw 1 2 5 D a formed at the lower end of the inner circumference of the outflow cylinder 1 25 D. As a result, the restrictor plate 124D is detachably attached to the lower end of the outflow cylinder portion 125D. At the lower end of the outer periphery of the aperture plate 124 Dd, a mounting knob 124 Df for facilitating the mounting operation is formed.

In order to facilitate such a bonding operation, the following configuration is adopted. That is, the first tubular connecting portion 2 26 is formed to be longer downward than the outflow tubular portion 2 25, and the second tubular connecting portion 2 27 is formed as the first tubular connecting portion 2 26 It is formed longer downward. As a result, the tubular portion located on the inner peripheral side is shorter than the tubular portion located on the outer peripheral side, so that the inner wall surface of the first tubular connecting portion 226 and the inner wall surface of the second tubular connecting portion 227 are formed. The inner tube does not interfere with the application of the adhesive, facilitating the bonding operation.

Fig. 35 is a view of the drain socket 220 viewed from the side, and Fig. 36 is a bottom view of the drain socket 220. As shown in FIGS. 35 and 36, a socket fixing portion 228 is formed on the bottom of the drainage socket 220.

In other words, the screw fixing parts 229a and 229a are the same as the lower end fixing part 211d of the toilet body 211 even when the drainage socket 220 is turned back and forth. It is formed so as to be located at a position.

FIG. 40 is an enlarged cross-sectional view showing the vicinity of the washing water retaining section 230 mounted on the upper part of the drainage socket 220, and FIG. 41 is a top view of the washing water retaining section 230. In FIG. 40 and FIG. 41, the washing water retaining section 230 includes a retaining main body 231, and a rubber mounting body 2332. The retaining body 2 31 has a cylindrical side wall 2 31 a fitted to the toilet connection section 2 21 on the upper part of the drainage socket 220 and an inner peripheral side from a lower end of the side wall 2 3 1 a. And a holding recess 2311d for supporting the rubber mounting body 232, which are integrally formed of resin. are doing. In addition, the rubber mounting body 2 32 has an annular fixing projection 2 32 a that is press-fitted into the holding recess 2 3 1 d to be mounted on the retaining body 2 3 1, and a drain pipe 2 1 1 b Part 2 3 2 that seals the outer periphery of the discharge port 2 16, and a fold part 2 3 that is formed along the inner periphery of the seal part 2 3 2 b and supports the periphery of the drain pipe 2 1 1 b 2 c and an upper diaphragm 2 32 d, which are integrally formed of rubber. That is, the retaining body 2 31 of the washing water retaining section 230 is mounted on the upper part of the drainage socket 220, and the sealing section 23 of the rubber mounting body 23 2 Connect with the outer circumference of the drain pipe 2 1 1b sealed. The washing water retaining section 230 is provided with two restrictors, an upper restrictor 23d and a lower restrictor 2311b, in order from the upstream side, and from the discharge port of the drain pipe 211b. Discharged The area of the flow passage is narrowed so that the collected washing water temporarily stays and triggers a siphon.

Next, the operation of installing the flush toilet 210 will be described. First, when the drain pipe PA shown in FIG. 12 (A) is installed at a distance L1 (120 mm) as shown in FIG. 13 (A), the drain pipe 220 is used. The operation of installing the toilet body 2 1 1 will be described.

FIG. 37 is an explanatory diagram for explaining the work of installing the drainage socket 220. First, the drain pipe P is cut at a height of 60 mm from the floor. After that, check the front and back of the drain socket 220, and align the center line of the drain socket 220 with the center line of the toilet body 211 so that the first cylinder of the drain socket 220 is aligned. Insert the connection part 222 into the drain pipe P, and temporarily position the drain socket 220 as shown in FIG. At this time, drainage socket 2

Reference numeral 20 denotes a temporary arrangement so that the toilet connection section 2 2 1 is directed forward. Next, write a writing line for positioning along the lower edge of the drainage socket 220 on the floor surface FL, and screw holes 2228b of the socket fixing part 228 (Fig.

Drill a pilot hole in the floor surface FL using 35, Fig. 36).

Next, the drainage socket 220 is separated from the floor surface FL, and an adhesive is applied to the inner wall of the first cylindrical connection portion 226 of the drainage socket 220. Apply adhesive also. Then, the first cylindrical connecting portion 226 is fitted to the drain pipe P so that the drain socket 220 is returned to the position where the temporary positioning has been performed. As a result, as shown in FIG. 32, the first cylindrical connecting portion 226 is connected to the drain pipe P via an adhesive. In this state, the drainage socket 220 is fixed to the floor surface FL by screwing it into the screw holes 228b at four places of the socket fixing portion 228.

Then, as shown in Fig. 33, align the outlet 2 2 1 6 of the toilet body 2 1 1 with the inlet 2 2 1 a of the toilet connection 2 2 1 of the drain socket 2 20. Install the toilet body 2 1 1 on the floor FL.

And stool By inserting screws 2 229 b and 229 b into the lower end fixing portion 2 1 1 d of the main body 2 1 1 and the toilet fixing portions 2 229, 2 29, respectively, the toilet body 2 1 1 is drained by the drain socket. Fixed at 220. Then, the toilet body 2 1 1 is fixed to the floor surface FL through another fixing member (not shown).

5X RE

Next, as shown in Fig. 13 (B), the drain socket 220 is connected when the drain pipe PA is installed at a distance L2 (200 mm) from the front wall WF of the toilet room. The operation will be described. This construction work is the same as the work described above, except that the installation direction of the drainage socket 220 is different between the front and rear. That is, as shown in FIG. 39, the drainage socket 220 is arranged so that the toilet connection portion 221 faces the front wall WF. Thus, even when the position of the drain pipe P is different, the toilet body 2 11 can be installed at the same location only by changing the position of the drain socket 220.

Therefore, according to the above-described embodiment, even when the drain pipes P are installed at different positions, the direction in which the drain socket 220 is attached is changed, so that the same position in the toilet room can be obtained. The toilet body 2 1 1 can be installed in the toilet. Therefore, it is not necessary to use a different drain socket 220 according to the construction position of the drain pipe P.

Next, the installation work of the toilet body 211 when the outer diameter of the drain pipe P is different is performed as follows. That is, as shown in FIG. 12 (C) and FIG. 12 (D), when the drain pipe PC or the drain pipe PD having the outer diameter D2 is used, the drain socket 220 shown in FIG. The same operation as described above is performed except for the operation of applying an adhesive to the inner peripheral surface of the second cylindrical connection portion 227 of the second embodiment. In other words, the drainage socket 220 is the same, and the surface to which the adhesive is applied may be changed according to the outer diameter of the drainage pipes PC and PD. In addition, as shown in FIG. 34, the gap d 1 between the outflow cylindrical portion 2 25 and the first cylindrical connecting portion 2 26 and the first cylindrical connecting portion 2 26 and the second cylindrical connecting portion 2 Since the gap d2 with 27 is larger than the wall thickness t2 of the drain pipes PB and PD, These drain pipes P having a large thickness t 2 can be connected by the same drain socket 220.

Therefore, the drainage socket 220 differs only in its direction or the surface to be coated with the adhesive as appropriate, and the other conditions are the same, but the outside diameter, wall thickness and construction position are different. It is compatible with various drainage pipes P shown in 13 and has excellent workability.

Further, as shown in FIG. 40, the drainage socket 220 has a washing water retaining section 230 and thus has an effect of rapidly generating a siphon.

When the washing water is supplied from the washing water supply means (not shown) to the ball portion 211a of the toilet body 211, the washing water is transferred to the drain socket 220 through the drain pipe 211b. Inflow. At this time, the washing water retaining section 230 is provided with an upper throttle 23d near the inlet 22a and a lower throttle 23b downstream from the inlet. Since the area is locally changed in two steps to increase the delay effect of the washing water in the connection flow path 223a, siphon generation can be easily induced. Moreover, since the throttle is formed in two stages, the upper throttle 2 32 d and the lower throttle 2 3 1 b, the flow path area per power point is larger than when the throttle is formed at one power point. As a result, waste is not easily clogged and drainage is quickly realized.

In addition, since the washing water retaining portion 230 is formed separately from the drainage socket 220, there are restrictions on manufacturing conditions such as die removal during the injection molding of the drainage socket 220. Instead, it is possible to form the lower diaphragm 2311b and the upper diaphragm 2332d of complicated shapes in consideration of the optimal design conditions for inducing the siphon.

Further, the drainage socket 220 is provided with a connecting pipe section 22 3, and the inclined connecting flow path 2 23 a in the connecting pipe section 22 3, that is, the inflow port 2 21 a and the outflow port Since the eccentricity of 2224a is established, the effect of delaying the washing water can be obtained at the upper portion of the connection flow path 223a, so that the siphon is more easily generated. In addition, the connecting channel 2 23 a does not require a large draft angle of the mold during injection molding, that is, the pipe area does not need to be increased unnecessarily. Thus, the siphon can be quickly generated and a large siphon power can be obtained.

Next, another example of the drainage socket according to the above embodiment will be described. FIG. 42 is a sectional view showing a drainage socket 220B and a washing water retaining section 230B according to the eighth embodiment. In FIG. 42, the drain socket 222B is composed of a straight pipe in which the inlet 2211Ba and the outlet 2224Ba are concentric, and the outlet cylinder 2225. The cleaning water retaining portion 230B is fitted and bonded to B.

That is, the washing water retaining portion 230B has a cylindrical side wall portion 2311Ba and a narrowed portion 2311Bb protruding inward from the side wall portion 2311Ba. The outer peripheral surface of the side wall portion 2311Ba is adhered to the inner periphery of the outflow tube portion 25B. Since such a narrowed portion 2311Bb is formed separately from the drainage socket 220B, it is not restricted to the shape of the drainage socket 220B but goes to the downstream side. Thus, it can be formed under conditions optimal for the generation of siphons so that the flow path area is reduced.

FIGS. 43 to 45 are cross-sectional views showing modified examples of the washing water retaining portion 230B of FIG. That is, in contrast to the washing water stagnant portion 230 B in FIG. 42, the washing water stagnating portion 230 C in FIG. 43 is an example in which a throttle portion 231 Cb is formed on the upstream side. Further, the washing water retaining portion 230D of FIG. 44 is an example in which a throttle portion 231Db is formed on the downstream side. Further, the washing water retaining portion 230E in FIG. 45 has a throttle portion 231Eb at the most downstream side, and the flow passage area where the flow passage area is temporarily increased from the upstream side to the downstream side. It has 2 3 1 Ec. By such a flow path 231Ec, the effect of temporarily staying on the upstream side of the throttle section 231Eb is increased, and generation of a siphon can be quickly induced.

FIG. 46 to FIG. 52 are cross-sectional views showing another embodiment relating to the washing water retaining means. The resin plate is fixed to the lower end of the outflow cylinder. That is, the washing water retaining portion 230F in FIG. 46 has an annular engaging portion 230Fa on its outer peripheral portion, and the annular engaging portion 230Fa is connected to the outflow cylindrical portion 22. It is fixed by fitting to the outer periphery of the lower end of 5B.

It is transmitted to the discharge mechanism after 25 without waste.

The water stored in the wash water tank WL, which is urged by the free fall, is supplied to the wash water supply passage 3 4 1 at a stretch as wash water. For this reason, the stagnant portion 341 a formed obliquely downward from the washing water supply channel 341 becomes full after the start of washing, and a portion of the washing water flows from the branch hole 342 to the rim water supply passage 344. Supplied to 3. The washing water supplied to the rim water supply passage 343 is discharged from a water discharging hole 344 provided on the back side of the rim portion 321 toward the ball portion 324.

Next, the discharge mechanism will be described. As shown in FIG. 53, a drainage channel 330 that is a flow path for water and dirt is formed at the end of a discharge port 325 formed in the depth of the concave portion 326 as a waste pool. I have. The drainage channel 330 is connected to the connecting channel 331 and the connecting channel 331 extending obliquely upward from the outlet 3225, and the rising channel 332 extending upward diagonally. It is composed of a descending route 3 33 that is continuous with the route 3 32 and extends downward. The height from the floor FL at the place where the flush toilet 310 is installed to the end of the descending route 3333 is about 120 mm.

As shown in Fig. 53, the descending channel 3 3 3 passes through the weir 3 3 4 which is the highest position below the inner wall of the ascending channel 3 3 2, and then drains almost vertically downward. Extending toward zero. For this reason, the drainage channel 330 near the weir 334 is bent. The portion having such a shape is hereinafter referred to as a bent portion 335.

These channels are formed integrally with the ceramic flush toilet 310 by shaping the flow channel shape into a plaster mold or a resin mold, but are separate members from the flush toilet 310. It is also possible to form a flow path with. For example, all or some of these flow paths may be formed of another member such as a resin and connected to the discharge port 325.

The washing water from the jet outlets 3 22 described above is gushered toward the outlets 3 25, and this jet causes the water RW in the connection passages 3 31 and the ascending passages 3 32 to be discharged. The dirt accumulated in the recesses 3 26 is pushed up in the direction of the weirs 3 3 4. As a result, the water level in the ascending channel 3 32 rises rapidly beyond the normal water level line WL, and the connecting channel 3 31, the ascending channel 3 32 and the bent portion 3 3 5 5 immediately become full and bent. A water level difference occurs between the tip of the water filled in the part 335 and the surface of the stored water RW in the ball part 320. Due to this water level difference, a pressure difference is generated between the inside of the descending path 3333 and the ball section 320, and a downward pulling force is generated. Such an effect is hereinafter referred to as a siphon effect. By this siphon action, the dirt in the ball portion 320 is drawn in the direction of the weir 334 together with the dirty water RW and the washing water.

In addition, the descending path 333 has, at its end portion, an extended portion 3333a having an expanded pipe diameter and an end narrowed portion 3333b having an opening area smaller than that of the extended portion. The restricting structure formed by the extension part 33 33a and the end restricting part 33 33b makes it possible to temporarily retain the washing water passing through the descending path 33 33, and the duration of the siphon action Can be extended.

The descending path 3 3 3 is connected to a drain pipe 3900 made of vinyl chloride, which has risen from the floor FL, via a drain socket 36 0 made of resin. It corresponds to the "sewage pipe" in the claims. The distance from the rear end of the flush toilet 310 shown in Fig. 53 to the center of the drain pipe 3900 is set to 180 mm, and the flush water installed in the flush toilet 310 is set to 180 mm. The distance from the rear end of the WL to the center of the drain pipe 390 is 19 O mm. In other words, if the drain pipe 390 is set up at a position 200 mm from the wall of the toilet room, the set of the flush toilet 310 and the wash water tank WL will be installed in the wash water tank WL. It can be installed with a clearance of 1 Omm between the back and the wall of the toilet room. Thus, if the flush toilet 310 and the flush water tank WL are set, the drain pipe 390 can be provided at a position close to the wall on the building side. As a result, the distance from the drain pipe 390 to the pipe space is shortened, and a smooth transfer of waste can be ensured. Of course, if the clearance with the wall of the toilet room is not considered, the above distance can be set to a value of 20 Omm or less.

Figure 54 shows the cross-sectional details of the drainage socket 360. As shown in FIG. 54, the drainage socket 360 is a base member 380 fixed on the floor FL with a bolt 385, and a member connected to the base member 380. It is composed of two members, a main body member 371 on which a main pipeline 373 as a flow path for the stored water RW, the washing water and the filth is formed. The base member 380 corresponds to the first member in the claims, and the main body member 371 corresponds to the second member in the claims. Hereinafter, details of each member will be described.

As shown in FIG. 54, the main body member 371 is provided at the upper end thereof with a descending passage fitting portion 371a into which the end of the descending passage 3333 enters. The end of the descending way 3 3 3 is installed on the installation surface 37 1 b of the descending way fitting part 37 1 a. The drainage socket 360 is connected to the descending route 3333 at this installation surface 371b.

A hollow and cylindrical main conduit 373 is formed below the descending passage fitting portion 371a. The main conduit 373 serves as a flow passage for the reservoir water, washing water, and filth flowing from the descending passage 333. The cross-sectional area of the main pipeline 3 7 3 is It decreases sharply near the entrance of the road 373, and then gradually decreases toward the exit of the main pipeline 373. As described above, the main pipeline 373 is provided with two types of throttle portions, large and small.

Around the outer periphery of the main conduit 373, two concave portions, a first part-shaped concave portion 364 and a second annular concave portion 362, are formed in the order close to the main conduit 373. Both the first annular concave portion 364 and the second annular concave portion 362 are grooves formed along a concentric circle on the outer periphery of the main pipeline 373. In addition, the first annular concave portion 36 4 and the second annular concave portion 36 2 are formed, so that the first annular concave portion 36 4 and 36 2 has a first annular concave shape projecting downward. The convex portion is 3 7 4.

As shown in FIG. 54, a drain pipe 390 is inserted into the second annular concave portion 362. The drain pipe 390 is held by the elastic force of the ribs 366 provided on the inner peripheral wall and the outer peripheral wall above the second annular concave portion 362.

The ribs 366 are provided by bonding rubber having a predetermined thickness with low elasticity to the inner peripheral wall and the outer peripheral wall. The ribs 36 on the inner peripheral wall side and the ribs 36 6 on the outer peripheral wall side are bonded in a positional relationship facing each other, and the tip of the rib 36 6 on the inner peripheral wall side and the rib 36 6 on the outer peripheral wall side There is a gap of about 1.5 mm between the top and the end of the 6. Therefore, the drain pipe 390 is weakly pinched by the rib 366 by being inserted between the rib 366 on the inner peripheral wall side and the rib 3666 on the outer peripheral wall side. 390 is connected to the main body member 371.

As shown in FIG. 54, a second annular convex portion 368 having a cylindrical shape and projecting downward is formed outside the second annular concave portion 362. At the tip of the second annular projection 368, an engagement piece 389 projecting in the direction of the outer peripheral surface is formed. By fitting the second annular convex portion 368 having the engaging piece 389 into the base member 380, the drainage socket 360 is integrated. In addition, the engagement pieces 389 are formed at four positions at the tip of the second annular convex portion 368. In this regard, the second annular convex portion 368 is connected to the base member 388. It will be described later together with the details of the method of fitting to 0. In a state where the drainage socket 360 is in the form of a body, the cover portion 389, which is the lower peripheral wall of the main body member 371, covers the base member 380 from the outside. In addition, a window 388 described later is formed in a part of the cover part 389 (not shown in FIG. 54).

Next, the base member 380 will be described. The base member 380 has a donut shape having a hollow portion slightly larger in diameter than the outer diameter of the drain pipe 390 at the center thereof. In the base member 380, a circumferential groove having a depth substantially equal to the size of the second annular convex portion 368 is formed from the top surface to the vicinity of the bottom surface. The portion formed by the peripheral groove is called an annular concave portion 384. The above-described second annular convex portion 368 of the main body member 371 is inserted into the annular concave portion 384.

An engagement portion 382 for engaging an engagement piece 389 at the tip of the second annular protrusion 368 is provided on the outer peripheral wall of the annular recess 384. The configuration of the engaging portion 382 will be described with reference to FIGS. 55 to 57. FIG. 55 is an explanatory view showing the upper surface of the base member 380. As shown in FIG. 55, the base member 380 includes three regular engagement piece engagement portions 3882a and one projection engagement piece engagement portion as the engagement portions 382. 38 2 p is formed. In FIG. 55, the front direction of the base member 380 is shown in the rightward direction, and the projecting engagement piece engaging portion 382p is formed of the base member 380. Is located on the front side (right side in FIG. 54).

As shown by the two-dot chain line in FIG. 55, the tip of the second annular convex portion 368 on the main body member 371 side has three short regular engagement pieces 389 a and One long protruding engagement piece 389 p is formed. The normal engaging piece 389a is engaged with the normal engaging piece engaging portion 382a of the base member 380, and the projecting engaging piece 389p is connected to the base member 380p. With the protruding engagement piece engaging portion 3882p of the second member. In addition, as shown in FIG. 55, the normal engagement piece 389 a also protrudes from the outer peripheral surface of the base member 380 when engaged.

As shown in Fig. 55, the normal engaging piece engaging portion 3882a and the protruding engaging piece engaging portion 3882p are arranged from the top surface 380a of the base member 380 toward the bottom surface. True The longitudinal grooves 3882b and 382q extending straight, and the lateral grooves 3882c and 38 extending horizontally from the longitudinal grooves 3882b and 3882q. 2 r is formed. The vertical groove 3 8 2 q and the horizontal groove 3 8 2 r are

It is formed at a depth deeper than 2b and the lateral groove 382c, and the vertical groove 382q penetrates the outer peripheral wall of the base member 380.

Fig. 56 shows the vertical grooves 3882b and the horizontal grooves 3882c formed in the normal engaging piece engaging portion 3882a. FIG. 56 is an explanatory diagram showing a cross section when the engaging portion 382 in FIG. 54 is cut along the center line C-C. As shown in FIG. 56, eight horizontal grooves 3882 c are formed in the normal engagement piece engaging portion 3882 a from the top to the bottom of the vertical groove 382 b. Both the width of the vertical groove 382 and the height of the horizontal groove 382c are formed so that the engagement piece 389a can enter, but the height of the horizontal groove 382c is at the intermediate position. The height is slightly lowered near the projection 3 81. It should be noted that eight lateral grooves 382 r are also formed in the protruding engagement piece engaging portion 382 p in the same manner as described above.

When the main body member 371 is put on from above the base member 380 configured as described above, as shown in FIGS. 55 and 56, the four The engagement pieces 3889a and 3889 enter the vertical grooves 3882b and 3882q of the respective engagement portions 3882a and 3882p. Thereafter, when the main body member 37 1 is rotated clockwise at a predetermined position, the four engaging pieces 3 89 a and 3 89 p are turned into the respective engaging portions 38 82 a and 38 82 p. Enter the lateral grooves 3882c and 3882r. By rotating the main body member 37 1 with a certain force or more, the engaging pieces 3 89 entering the lateral grooves 3 82 c and 38 2 r get over the convex section 3 81, and the four engaging pieces 3 8 9 a, 3 8 9 p is each engaging part 3 8 2 a,

Engage with 3 82 p. As a result, the main body member 371 is mounted on the base member 380.

In FIGS. 53 and 54, the four engagement pieces 3889a and 3889p at the tip of the second annular convex portion 368 are connected to the lowermost horizontal grooves 3882c and 38, respectively. 2 r and the height of the drainage socket 360 from the floor FL Is also low.

The structure of the drain socket 360 has been described above. Next, a method of attaching the drainage socket 360 to the descending passage 333 of the flush toilet 310 and the drainage pipe 390 will be described. First, an adhesive is applied to the back side of the base member 380, the hollowed-out central portion of the base member 380 is passed through a drain pipe 390, and the base member 380 is placed on the floor surface. Adhere on FL and fix with 4 bolts 3885. Next, cover the main body member 371, from above the base member 380, so that the drain pipe 390 is inserted into the second annular concave portion 362 of the main body member 371. Insert the convex portion 368 into the annular concave portion 384.

Next, the height of the drainage socket 360 from the floor surface FL is adjusted so as to match the height from the floor surface F to the end of the descending route 3333. The method of this adjustment will be described below with reference to FIGS. 57 to 59. FIG. 57 is an explanatory diagram showing a perspective view of the base member 380. FIG. As shown in FIG. 57, a vertical groove 3882q and eight horizontal grooves 3882r are exposed on the outer peripheral surface in front of the base member 380. Eight graduation lines are engraved at the pitch of 10 mm in the height direction next to each lateral groove 3 8 2 r, and next to each graduation line, a descending path 3 3 3 from the floor surface FL is provided. A numerical value indicating the height of the installation surface to be installed is shown. Specifically, as shown in FIG. 57, numerical values from 130 mm to 200 mm are shown in units of 10 mm.

The base member 380, on which the numerical values are displayed, is covered with the body member 371, and the four engagement pieces 389a, 389p are connected to the lowermost horizontal grooves 382c, 382r. FIG. 58 shows a front view of the drainage socket 360 when engaged in FIG. As shown in FIG. 58, in a state where the base member 380 and the main body member 371 are combined, the protruding engagement piece 389 p is engaged with the protruding engagement piece 389 p. The horizontal groove 382 r and the “graduation indicating the height of 130 mm” engraved next to the horizontal groove 3822 r are used to hollow out a part of the outer periphery of the main body member 371 in a horizontal direction. Exposed from the formed window part 3 8 8 are doing. In other words, the four engaging pieces 389a, 389p are connected to the lowermost lateral groove 3

When engaged at 8 2 c and 3 8 2 r, the height from the floor surface FL of the drainage socket 360 to the installation surface 37 1 b is set to 130 mm, which indicates this state. To this end, the protruding engagement piece 389p arranged at the position corresponding to the "scale indicating height 130 mm" is shown through the window 388. Fig. 58 shows the drain socket 360 shown in Fig. 53 viewed from the front (that is, the surface located on the tip side of the flush toilet 310 when it is attached to the flush toilet 310). Shows the same situation as when In the flush toilet 310 shown in FIG. 53, the height from the floor surface FL at the installation location of the flush toilet 310 to the end of the descending passage 3333 is about 13 O mm. Therefore, as shown in Fig. 58, the drainage socket 360 has the lowest height from the floor F to the installation surface 371b (the height of 130mm). ing. Adjustment of the height of the drainage socket 360 from the floor surface FL is performed as follows. When the main body member 371, engaged in the lateral grooves 3882c, 3882r, is rotated counterclockwise with a certain force or more, the four engaging pieces 389a, 389 p moves over the convex part 381, and moves to the position of the vertical grooves 3882b, 3882q. As a result, the four engagement pieces 3 8 9a, 3 8

The engagement state of 9p is released, and the main body member 37 1 is vertically movable along the vertical grooves 3882b and 3882q. Since the drain pipe 390 is weakly held by the rib 366, when the main body member 371 is moved up and down, the rib 366 slides on the surface of the drain pipe 390. I do. Therefore, the drain pipe 390 itself does not move up and down as the main body member 371 moves.

Next, the main body member 371 is moved up and down to a desired position. Whether or not the user has moved to the desired position can be confirmed by referring to the above-mentioned “scale engraved corresponding to the numerical value”. For example, when raising the height of the drain socket 360 from the floor surface FL to 130 mm from the state shown in Fig. 58 to 130 mm, the projecting engagement piece 3 89 p Body member 3 until the position of You only need to raise 7 1.

The window portion 3888 is slightly open in the direction in which the protruding engagement piece 389p engages the lateral groove 3882r (leftward in FIG. 58). For example, in Fig. 58, the drainage socket 360 is large enough that a margin is formed on the left side of "1" which is the first character of the numerical value indicating the height from the floor FL. An opening is made. For this reason, when the height is adjusted, the engagement is released even if the position of the window portion 3888 moves counterclockwise due to the rotation of the main body member 371 in the counterclockwise direction. All the digits of the numerical value indicating the height of the drainage socket 360 together with the protruding engagement piece 389p located in the longitudinal groove 3882q appear through the window 3888. Therefore, even while adjusting the height of the drainage socket 360 from the floor surface FL, it is possible to confirm to which position the main body member 371 has moved while referring to the numerical values.

Figure 59 shows the drainage socket 360 when the height from the floor F of the drainage socket 360 is adjusted to 20 Omm. Since the projecting engagement piece 389p and the window 3888 are both formed on the main body member 371, the projecting engagement piece 38 9p and window 3 8 8 also move up and down. Therefore, as shown in Fig. 59, when the height of the drainage socket 360 from the floor F is set to 20 Omm, the protrusions that have moved upward together with the windows 3888. The mating piece 389p is engaged in the uppermost lateral groove 3882r, and the protrusion located at the position corresponding to the `` scale indicating height 200 mm '' through the window 388. The shape engagement piece 389p appears. As described above, the height of the drainage socket 360 from the floor surface FL is represented by the position of the projecting engagement piece 389p on the front of the drainage socket 360. After adjusting the height of the floor 360 from the floor F to the height from the floor FL to the end of the descending path 33 33, a seal for preventing water leakage is placed on the fitting part 3 71 a of the descending path. Attach a material (not shown) and insert the end of the downcomer 3 33 of the flush toilet 3 Ί 0 into the downcomer fitting part 37 1 a. As a result, it is possible to reach the downcomer 3 33 of the drainage socket 360 and the drainage pipe 390 Installation is completed.

As described above, according to the drainage socket 360, the overall length of the drainage socket 360 can be changed by adjusting the height of the drainage socket 360 from the floor surface FL. The total length of the drainage socket refers to the distance from the portion of the drainage socket 360 located closest to the downcomer channel 3333 to the portion located closest to the drainage pipe 390 side. Speaking of 54, it means the distance I 1 from the top of the descending-way fitting portion 371 a to the bottom of the base member 380 in contact with the floor surface FL.

FIG. 60 shows a vertical cross section when the drainage socket 360 whose height from the floor surface FL is adjusted to 200 mm is connected to another flush toilet 510. The flush toilet 5110 has a drainage channel composed of a connection channel, an ascending channel, and a descending channel 5333, similarly to the aforementioned flush toilet 310. On the other hand, the height from the floor F to the end of the descending route 5333 is different from that of the flush toilet 310, and is about 200 mm.

In the state shown in FIG. 60, the four engagement pieces 389a, 389p at the end of the second annular convex portion 368 are engaged with the uppermost lateral grooves 3882c, 3882r. It matches. As a result, the main body member 371 is combined with the base member 380. The main body member 371 is connected to the drainage pipe 3900 by sandwiching the drainage pipe 3900 with a rib 366 attached to the lowermost portion of the second annular concave section 362. In addition, the main body member 371, on the installation surface 371, of the descending passage fitting portion 371, a, terminates the end of the descending passage 533, the height of which is approximately 200 mm from the floor surface FL. As a result, it is connected to the descending route 5 3 3. In this way, even when the height of the drainage socket 360 is adjusted and the total length of the drainage socket 360 is changed, the downcomer 533 and the drainage pipe 390 are connected to the drainage socket. The connection is good via the connection 360.

Comparing the positional relationship between the main body member 371 and the base member 380 in FIG. 60 with the case shown in FIG. 54, the positional relationship between them has been changed so as to be away from each other. . Specifically, the distance from the floor surface FL to the installation surface 37 1 b of the main body member 371, The value has been changed to mm. As a result, the distance I2 from the top of the descending-way fitting portion 371a to the bottom surface of the base member 380 is 70 mm longer than the distance I1 shown in FIG.

In the ninth embodiment described above, the drainage socket 360 is divided into a plurality of members, namely, a main body member 371, and a base member 380, which are separable in the direction in which the main pipeline 373 extends. Therefore, depending on the combination of the members, the flow path of the stored water RW and the washing water can be formed in various forms. In addition, since the total length of the drainage socket 360 can be freely changed, the flush toilet 310 and the drainage pipe 390 can be connected in a plurality of forms, and the drainage socket can be connected. It is possible to standardize the model 360.

In the ninth embodiment, such a change in the total length of the drain socket 360 is realized by changing the height of the drain socket 360 from the floor surface FL. Therefore, it is possible to connect toilets having different heights from the floor surface FL to the end of the descending route 3333 using the same drainage socket 360, and the workability is further improved.

The drainage socket 360 of the ninth embodiment has a height from the floor surface FL of the drainage socket 360 after the height adjustment to the installation surface 371 b on the side surface of the main body member 371. The value of is displayed visually. Therefore, the height of the drainage socket 360 can be adjusted while confirming the degree to which the height is changed, and the workability associated with the adjustment is further improved. For example, if the scale of the drain socket 360 is set to the design dimension indicating the height from the descending path of the flush toilet 310 to the floor F, a good connection state can be secured. . Therefore, at the construction site, the dimensions from the floor surface FL to the installation surface 37 1 b and the dimensions from the end of the descending route 3 33 3 were measured one by one, and the drainage socket was positioned while being aligned with the flush toilet 310. There is no need to adjust the dimensions of 360, making the adjustment work smoother.

In the ninth embodiment, the height value from the floor surface FL of the drainage socket 360 to the installation surface 3771b is represented by the position of the projecting engagement piece 389p. Obedience Thus, the height value can be displayed without adding a special display mechanism.

The clamping of the drain pipe 390 by the ribs 366 described in the ninth embodiment is an example of a method of connecting the drain pipe 390 to the drain socket 360, and other methods. The drain pipe 390 may be connected to the drain socket 360 by using a pipe. For example, an elastic body other than rubber may be used as the rib 366. Further, the same material may be used for both the rib 366 and the drainage socket 360 body, and may be formed integrally with the second annular concave portion 362. If the water passing through the drainage socket 360 does not leak to the outside of the drainage pipe 390, the drainage pipe 390 and the drainage socket 360 should be fitted or bonded. Instead, it may be merely inserted into the second annular concave portion 36 2.

Further, in the ninth embodiment, the drain pipe 390 is connected to the second annular concave portion 362 of the main body member 371 of the drain socket 370, but is similar to the second annular concave portion 362. This structure may be formed on the base member 380, and the drain pipe 390 may be connected to the base member 380 of the drain socket 360.

In addition, in the ninth embodiment, the four engaging pieces 389a, 389p of the main body member 371, and the respective engaging portions 3882a, 3882p of the base member 380 are formed. The engagement structure is merely an example of a structure for changing the positional relationship between the main body member 371, and the base member 380, and the main body member 371, and the base member 380 are formed by using other structures. May be changed. For example, one hole was formed in the body member 371, and a plurality of holes were formed in the height direction of the base member 380, respectively. After aligning the positions of the holes and the holes formed in the base member 380, it is possible to consider a configuration in which a pin is inserted through these holes.

In the ninth embodiment, the base member 380 was adhered to the floor surface FL and fixed with the bolt 385. However, the base member 380 does not necessarily need to be fixed to the floor surface FL. Place member 3800 on floor F It may be. In such a case, the height adjustment of the drainage socket 360 can be performed after the base member 380 is placed on the floor surface FL as described above. Work efficiency will be better if the 380 is done before placing it on the floor FL. That is, the base member 380 and the main body member 371 are combined in advance to adjust the drainage socket 370 to a desired height, and thereafter, the base member 370 combined with the main body member 371 is combined. 80 may be placed on the floor FL.

Next, a tenth embodiment of the present invention will be described. FIG. 61 is an explanatory view showing a vertical cross section when the flush toilet 810 and the drain pipe 8390 are connected using the drain socket 8360 according to the tenth embodiment of the present invention. . A flush toilet 810 and a drain socket 8360 shown in FIG. 61 include components substantially common to the flush toilet 310 and the drain socket 360 described above. In FIG. 61, the last three digits of the reference numerals for the common parts are represented by the same numerals as in FIG.

The drainage socket 8360 includes the same base member 8380 and main body member 8371 as in the ninth embodiment. Therefore, the height from the floor surface FL to the installation surface 837b of the main body member 8371 can be adjusted.

The drainage socket 8360 of the tenth embodiment includes a base member 8380, a main body member 8371, and a drain pipe socket member 372 attached to the main body member 8371. It consists of three members. The base member 8380 corresponds to the first member in the claims, and the main body member 8371 corresponds to the first member or the first flow path forming member in the claims. The socket member 372 in the drainage pipe corresponds to the second channel forming member recited in the claims.

A hollow and cylindrical main conduit 837 3 is formed below the descending passage fitting portion 371 a. The main pipeline 8337 serves as a flow path for the stored water, washing water, and filth flowing from the downcomer 833. The main pipeline 83733 is provided with the same two types of throttle portions as the main pipeline 3733 of the ninth embodiment.

As shown in Fig. 61, a third pipe formed around the outside of the main pipeline 8 3 7 3 A drain pipe socket member 372 is inserted into one annular concave portion 835. The socket member 372 in the drainage pipe is constituted by a combination of two members, that is, a substantially cylindrical first cylindrical portion 372b and a cylindrical second cylindrical portion 372c. Specifically, by bonding the upper end of the second cylindrical portion 372c to the end of the first cylindrical portion 372b, one socket member 372 in the drainage pipe is formed.

The socket member 372 in the drainage pipe is bonded to a desired position on the outer peripheral wall of the first annular concave portion 8364. Due to this bonding, the socket member 372 in the drainage pipe is integrated with the main body member 8371. By bonding the socket member 372 in the drainage pipe, the first cylindrical part 372b is expanded as a flow path that is continuous with the main pipe 837, with a pipe diameter larger than that of the main pipe 8373. A pipe 3 7 5 is formed. In addition, the second cylindrical portion 372 c forms a same-diameter pipe 376 having substantially the same diameter as the main pipe 833, as a flow path that is continuous with the expansion pipe 375. As described above, the socket member 372 in the drainage pipe is connected to the main pipeline 833, which is the flow path of the stored water RW, the washing water, and the filth formed in the main body member 8731, on the downstream side. It is extended. As shown in Fig. 61, the flow path of the stored water RW, washing water, and dirt is extended to a position below the floor surface FL in the drain pipe 8390 by the socket member 37 in the drain pipe. ing.

The first cylindrical portion 37 2 b is composed of a non-restricted portion 37 2 p, which is a portion maintained in substantially the same cross-sectional area as the starting end of the first cylindrical portion 37 2 b, and an end of the non-restricted portion 3 72 p. A first constricted portion 372 q is a portion in which the cross-sectional area of the end is gradually reduced toward the terminal end of the first cylindrical portion 372 b. In addition, the end of the first cylindrical portion 372 b is protruded horizontally toward the center of the expansion conduit 375, and then extends vertically downward. The cross-sectional area of b is also reduced at the end of the first cylindrical portion 37 2 b. The end portion of the first cylindrical portion 372b formed in this manner is hereinafter referred to as a second throttle portion 372r.

According to the drain socket 8360 having the above configuration, by changing the mounting position of the socket member 372 in the drain pipe to the main body member 8371, the drain socket 8360 is changed. Can change the overall length. In addition, In Figure 61, the total length of the drainage socket is the distance I from the top of the descending passage fitting part 837 1a to the end of the second cylindrical part 3772c of the socket member 3772 in the drainage pipe. It becomes 3.

Figure 62 shows the situation when the mounting position of the socket member 372 in the drainage pipe to the body member 8731 is changed. As shown in FIG. 62, the first cylindrical portion 37 2 b of the socket member 37 2 in the drainage pipe has a more twisted outer peripheral wall of the first annular recess 8 365 than the case of FIG. Glued to the lower side. For this reason, the distance I4 from the top of the descending passage fitting portion 8371a to the end of the second cylindrical portion 3772c of the socket member 3772 in the drainage pipe is the distance I shown in Fig. 61. It is longer than three.

By bonding the socket member in the drainpipe 372 to the lower side, the second cylindrical portion 372c of the socket member in the drainpipe 372 enters the deep position in the drainpipe 8390. are doing. For this reason, the first constricted portion 372q and the second constricted portion 372r are arranged at positions lower than the floor surface FL. In addition, the lengths of the expansion pipeline 375 and the same-diameter pipeline 376, which are the flow paths extending the main pipeline 833, are longer.

In the tenth embodiment described above, the drain socket 360 is referred to as a main pipe member 8371, a base member 8380, and a socket member 372 in a drain pipe. The structure is divided into a plurality of members that can be separated in the direction in which the water extends, so that the flow path of the stored water RW and the washing water can be formed in various forms by combining the members. In addition, the drainage socket 8

The total length of the drainage socket 8360 can also be freely changed by using 60. Therefore, the flush toilet 810 and the drain pipe 8390 can be connected in a plurality of forms, and the drainage socket 8360 can be shared.

The drain socket 8360 of the tenth embodiment is a socket member in the drain pipe 3

The total length of the drainage socket is changed by changing the position at which 7 2 is attached to the main body member 8 3 7 1. Therefore, the length of the flow path of the drainage socket 8360 can be changed to a desired length. In particular, in the tenth embodiment, The socket member 372 in the drain pipe is configured separately from the main body member 8371, and only the position of bonding the socket member 372 in the drain pipe to the first annular concave portion 8364 is changed. Accordingly, the length of the flow path can be changed to a desired length, and the flow path length can be easily changed.

In addition, since the socket member 372 in the drainage pipe is composed of a combination of a plurality of members, the first cylindrical portion 372b and the second cylindrical portion 372c, the work involved in changing the flow path length is simplified. can do. For example, both the first cylindrical portion 372b and the second cylindrical portion 372c are bonded to the first annular concave portion 8364, and only the first cylindrical portion 372b is bonded. A desired flow path length can be realized only by selecting one of three patterns in which neither the first cylindrical portion 372b nor the second cylindrical portion 372c is bonded.

Further, the above-mentioned socket member 372 in the drainage pipe has two throttle portions, a first throttle portion 372q and a second throttle portion 3772r. Therefore, the position of the throttle can be freely determined in consideration of the type of the toilet and the state of the drain pipe 830.

For example, when the above-mentioned drainage socket 8360 is used for a siphon-type toilet with a small amount of washing water, the socket member 372 in the drainage pipe is placed in the state shown in FIG. (It is a state where it is adhered to the position below 6). In this way, the point where water stays in the expansion pipeline 375 becomes lower, and the head difference between the staying point and the vicinity of the weir increases. Therefore, the suction power of the stored water and the washing water generated by the siphon action can be utilized more efficiently, and the suction power can be increased.

In addition, in the above case, the height of the drain pipe 8390 rising from the laterally pulled state (that is, the drain pipe) If the depth from the upper end of the 8390 to the inner bottom is low, only the first cylindrical portion 372 of the drain pipe socket member 372 is bonded, or The part 3 72 b may be bonded above the first annular recess 8 3 6 4. In this way, water will accumulate in the expansion line 375. It is possible to avoid interference with the drainage pipe 8390 while keeping the retaining point downward. Therefore, it is possible to improve the flushing performance of the toilet irrespective of the startup state of the drain pipe 8390.

Also, when the above drain socket 8360 is used for a non-siphon type toilet, it is not necessary to retain water in the drain socket 8360, so the socket member 3 in the drain pipe is used. It is not necessary to attach 72 to the first annular recess 8 3 6 4. Therefore, a common drainage socket 8360 can be provided for non-siphon toilets and siphon toilets.

Further, according to the drainage socket 8360 of the tenth embodiment, both the height of the drainage socket 8360 from the floor surface FL and the length of the flow path of the drainage socket 8360 are described. Can be changed. Therefore, even if the type of the installed toilet and the condition of the installed sewage pipe differ from one installation site to another, a constant washing performance can be ensured.

For example, when the above drain socket 8360 is used for two types of siphon-type toilets that have almost the same amount of washing water and have different heights from the floor surface FL to the end of the drainage channel, It is possible to give almost the same cleaning capacity to the siphon type toilets. Specifically, the height of the drainage socket 8360 from the floor surface FL is adjusted, and the socket in the drainage pipe is set so that both lower ends of the socket member 3772 in the drainage pipe are at the same position. What is necessary is just to contact the member 372 with the first annular concave portion 8364. In this case, since the flush water amount and the water retention point in the socket are the same for both toilets, uniform flushing performance can be obtained.

Next, an eleventh embodiment of the present invention will be described. FIG. 63 is an explanatory view showing a longitudinal section when the flush toilet 1310 and the drain pipe 13900 are connected using the drain socket 1360 according to the first embodiment of the present invention. A flush toilet 1310 and a drain socket 1360 shown in FIG. 63 have substantially the same components as the flush toilet 310 and the drain sockets 360 and 8360 described above. In FIG. 60, the lower three digits of the reference numerals for the common parts are represented by the same numerals as in FIGS. 53, 54 and 61. The drain socket 13360 of the eleventh embodiment is different from that of the ninth embodiment in that the base member 380 and the main body member 371 have a non-separable structure. Therefore, the drain socket 13360 is composed of two members, a main body member 1371 and a socket member 1372 in the drain pipe attached to the main body member 1371.

As shown in FIG. 63, the main body member 1371 has a main pipeline 1373 serving as a flow path for stored water RW, washing water, and filth. The main body member 1371 corresponds to the first flow path forming member recited in the claims. The socket member 1337 in the drain pipe is bonded to the main body member 1371 so that the main pipe 1373 can be connected to the floor surface in the drain pipe 1390 on the downstream side. It extends to a position below FL. The drain pipe socket member 1372 corresponds to the second flow path forming member recited in the claims.

As in the tenth embodiment, the socket member 1337 in the drainage pipe has two members, a first cylindrical portion 1337b having a substantially cylindrical shape and a second cylindrical portion 1372c having a cylindrical shape. By bonding the upper end of the second cylindrical part 1372c to the end of the first cylindrical part 13372b, one socket member 13572 in the drainage pipe is formed. Is done.

As shown in FIG. 63, the first pipe portion 1372b serves as a flow path that is continuous with the main pipe 1337, and is an expanded pipe whose pipe diameter is larger than that of the main pipe 1373. 1 3 7 5 is formed. In addition, the second cylindrical portion 1372c forms the same diameter pipe 1367 of the same diameter as the main pipe 1373 as a flow path that is continuous with the expansion pipe 1375. You. Also, the socket member 1 37 2 in the drainage pipe has the same non-restricted portion 1372 p, the first restricted portion 1372 q, and the second restricted portion 1372 as in the tenth embodiment. r is formed.

The method of attaching the socket member 1372 in the drainage pipe to the body member 1.371 is different from that of the tenth embodiment as follows. That is, an annular convex portion 1379 is formed on the outer side of the main conduit 1337 of the main body member 1371, and a flange 1 is formed on the inner peripheral wall of the annular convex portion 1379. The 379 a is formed integrally with the annular convex portion 139. Socket member in drain pipe described above The first cylindrical portion 1 372 b of 1 372 is bonded to this flange portion 139 a. Therefore, in Fig. 63, the total length of the drainage socket is, from the top of the descending passage fitting portion 1371a, to the end of the second cylindrical portion 1372c of the socket member 1337 in the drainage pipe. Distance to I5.

In this way, the drainage pipe 139 raised from the floor surface FL is inserted into the flange part 139a to which the socket member 137 in the drainage pipe is bonded. This drain pipe 139 is bonded to the inner peripheral wall of the annular projection 139. By this bonding, the drainage socket 1360 and the drainage pipe 1390 are connected.

Further, a mark indicating a position for cutting the first cylindrical portion 1372b is engraved on the first cylindrical portion 1372b of the socket member 1372 in the drainage pipe. This is shown in Figure 64. FIG. 64 is an explanatory view showing an appearance of the first cylindrical portion 1372b. As shown in FIG. 64, three scale lines are engraved on the outer peripheral surface of the first cylindrical portion 1372b at a pitch of 20 mm in the height direction.

In the vicinity of each of these graduation lines, when the first cylindrical portion 1372b is bonded to the flange portion 1379a, the first cylindrical portion 1337 extending below the floor surface FL is formed. A numerical value indicating the length of 2 b is engraved. Specifically, as shown in FIG. 64, numerical values from 40 mm to 100 mm are shown in 20 mm units. For example, when the first cylindrical portion 1 3 7 2 b is bonded to the flange 1 3 7 9 a without cutting, the end 1 3 7 2 g of the first cylindrical portion 1 3 7 2 b is It is located 100 mm below F. Also, 40 mm,

The numerical values of 60 mm and 80 mm extend below the floor surface FL when the first cylindrical portion 1 3 7 2 b is cut at the position of the scale line above each numerical value. The length of the first cylindrical portion 1 3 7 2 b is shown. For example, the first cylindrical portion 13 7 2 b cut at the position of the scale line of 60 mm is

When bonded to 79a, the end 1372g of the first cylindrical portion 1372b is arranged at a position 60 mm below the floor surface FL. Of course, as this numerical value, it is also possible to indicate the length of the first cylindrical portion 1372b and the second cylindrical portion 1372c extending below the floor surface FL. In addition, since these numerical values are displayed on the side surface used as the first cylindrical portion 1372b when cut at each scale line, the first cylindrical portion 1372b is cut after cutting. Also at the time of bonding, the length of the first cylindrical portion 1372 can be confirmed. Further, in FIG. 63 described above, the first cylindrical portion 1372b that is not cut is connected.

The first cylindrical portion 1 37 2 b is cut along a scale line of 60 mm and bonded to the second cylindrical portion 1 37 2 c, and a socket member in the drain pipe formed by this bonding 1 3 7 2 Fig. 65 shows the state when the first cylindrical part 13 7 2 b is attached to the collar 13 7 79a, as shown in Fig. 65. The distance I 6 from the top of the mating part 1 37 1 a to the end of the second cylindrical part 1 37 2 c of the socket member 1 37 2 in the drain pipe is longer than the distance I 5 shown in Fig. 63. It's getting shorter. In addition, below the floor surface FL, a socket in the drainage pipe is formed by adding the length of the second cylindrical portion 1372c to 60 mm, which is the length of the first cylindrical portion 1372b. Member 1 3 7 2 is extended.

The drain socket 1360 of the eleventh embodiment described above has the length of the socket member 1337 in the drain pipe projecting downward from the floor surface FL, and the length of the first cylindrical portion 1372. It can be changed by cutting b. Therefore, the flow path of the drainage socket 1360 can be changed to any length. Moreover, since the cutting position of the first cylindrical portion 1372b is indicated by a scale line, the cutting operation is smooth. In addition, near the scale line, a numerical value indicating the length of the first cylindrical portion 1372b that extends below the floor surface FL when cut at the position of each scale line is displayed. Therefore, it is necessary to determine the length of the drain pipe socket member 1 37 2 so that it does not interfere with the drain pipe 13 9 0 rising from the floor FL and the inside of the drain pipe 13 9 0. it can.

FIG. 66 shows a modified example of the above-mentioned first cylindrical portion 1372b. The first cylindrical portion 2 3 7 2 b shown in FIG. 6 does not have the non-restricted portion 1 3 7 2 P as in the first embodiment, and the first cylindrical portion 1 3 7 2 b A first constricted portion 2 3 7 2 q is formed in which the cross-sectional area of the starting end is gradually reduced toward the end. In addition, three scale lines are engraved on the outer peripheral surface of the first cylindrical portion 23722b in a height direction as a mark indicating a position for cutting the first cylindrical portion 23722b. . Above each of these graduation lines, a numerical value indicating the inner diameter of the first cylindrical portion 2372b at the cutting position of each graduation line is engraved. Specifically, as shown in FIG. 66, numerical values of 40 mm, 45 mm, and 50 mm are shown. These values are displayed on the side of the side used as the first cylindrical part 2 37 2 b when cut at each scale line, so the first cylindrical part 2 37 2 b is adhered after cutting In this case, it is also possible to confirm the inner diameter of the terminal end of the first cylindrical portion 23772b.

This first cylindrical part 2 3 7 2 b is cut at an arbitrary scale line and attached to the flange 1 3 7 9 a shown in FIG. Can be adjusted. For example, when cutting at a position with an inner diameter of 50 mm, the first cylindrical portion 23772b becomes shorter, so that the accumulated water RW and the washing water when passing through the first cylindrical portion 23772b are reduced. Staying state becomes weak. As described above, according to the first cylindrical portion 23772b, the stagnant state in the drainage socket 136 can be created in accordance with the performance of the attached toilet bowl. In the tenth and eleventh embodiments, the socket members 372, 1372 in the drainage pipe are connected to the first cylindrical part 372, b 137, and the second cylindrical part 372, respectively. Although the parts are divided into two parts, 2c and 1372c, the socket members 372 and 1372 in the drainage pipe may be composed of one member.

It is also possible to divide the socket member 3772, 1372 in the drainage pipe into three or more parts. For example, in the tenth embodiment, the flange portion 1379a is formed integrally with the annular convex portion 1379, but a member having the same shape as the flange portion 1379a is formed as an annular convex portion 1. It is formed separately from 379, and the combination of the flange 137a, the first cylinder 13772b and the second cylinder 13772c is a socket member in the drainage pipe. As an example, a configuration to be mounted on the annular convex portion 1379 can be considered. By doing so, it is possible to freely adjust the mounting position of the flange portion 1379a to the annular convex portion 1379. For example, the mounting position of the flange 1 37 9 a on the annular convex〗 3 79 9 If determined according to the rising height of the drain pipe 1 390 from the floor surface FL, the drain pipe 1 390 will be the inner peripheral wall of the annular projection 1 379 and the flange 1 379 Fits perfectly in the space surrounded by. Therefore, even if the rising height of the drain pipe 13900 differs at each installation site, the drain pipe 1390 is not cut to fit the drain socket 1360, and the drain socket 1 360 can be attached.

In the above-described tenth and eleventh embodiments, the method of bonding was adopted as a method of attaching the socket members 372, 1372 in the drainage pipe to the body members 371, 1371. The position of the drain pipe socket member 372 may be changed by using a method other than bonding, such as fitting or engagement. For example, the drain pipe socket member 372 may be replaced by the first A configuration or the like that can be slidably fitted to the peripheral wall of the annular concave portion 364 can be considered.

In addition, the degree of restriction provided in the main pipelines 375, 13773 and the expansion pipelines 375, 13775 can be arbitrarily determined according to the shape of the flow path of the washing water. . In addition, it is also possible to adopt a configuration in which a throttle is provided also in the same-diameter pipes 376, 1376. Further, in the above embodiment, a configuration may be adopted in which the centers of the main pipelines 375, 1373 and the centers of the expansion pipelines 375, 5375 are eccentric.

In the above embodiment, the numerical value engraved on the side surface of the socket member 1 37 2 in the drain pipe is as follows: `` When cut at the position of each scale line, it will extend below the floor surface FL. The numerical value indicating the length of the socket member 1 37 2 in the drain pipe and the numerical value indicating the inner diameter of the socket member 1 37 2 in the cutting position at the cutting position are shown. It is also desirable to show numerical values or information based on differences and types of toilets installed.

For example, the distance from the floor FL where the toilet is installed to the drainage pipe drawn horizontally below the floor FL is about 800 mm when installed on the first floor of a house, and installed on the second floor of a house. In this case, the value is considered to be about 10 Omm to 20 Omm. Therefore, "When cutting at the position of each scale line, These values should be recorded on the side of the drain pipe socket member 1 3 7 2 as a numerical value that indicates the length of the socket member 1 3 7 2 in the drain pipe that will extend below the floor FL. For example, a toilet contractor can immediately determine an appropriate cutting position based on the floor on which the toilet is installed, and does not hesitate in which of the displayed marks to cut. As a result, the drainage socket can be mounted satisfactorily and smoothly.

Also, in recent years, the amount of flushing water for the same siphon toilet varies greatly depending on the type and product number. Therefore, "the length of the socket member 1 37 2 in the drain pipe that extends below the floor surface FL when cutting at the position of each scale line" and "the drain sonai socket at the cutting position" If the toilet bowl part number is written in the vicinity of each scale line instead of the numerical value indicating `` inner diameter of member 1 3 7 2 '', the toilet contractor can immediately determine the appropriate cutting position according to the toilet bowl part number to be installed. In addition to this, it is possible to secure a suitable retention state in the drainage socket in consideration of the difference in the amount of washing water for each toilet.

In addition, if the above-mentioned socket member 372, 1372 in the drainage pipe is shipped together with the flush toilet, the construction due to the absence of the socket member 3722, 1372 in the drainage pipe can be performed. It is possible to reliably prevent postponement or loss of the socket member 3 7 2 1 3 7 2 in the drainage pipe at the construction site. In addition, it is also possible to provide only the socket member 372, 1372 in the drainage pipe as a single item, or to conduct ex post facto if the condition of the drainage pipe 390 or the type of flush toilet 310 installed cannot be changed. It is preferable in that it can take appropriate measures.

The ninth to eleventh embodiments can be modified as follows. For example, in the drainage sockets 360 and 136 of the above embodiment, the end of the descending path 333 and 1333 is received by the installation surface 371 of the fitting part 371a of the descending path. However, the end of the descending path 3 3 3, 1 3 3 3 does not have to be in contact with the installation surface 3 7 1 b, and the end of the descending path 3 3 3, 1 3 3 3 It suffices if it is located within the height of the junction 3 71 a. The load of the flush toilet 3110 and 1310 is received on the floor surface FL, and the installation surface 3 7 1 This is because the flush toilets 310 and 1310 do not receive a load on b. In addition, the drainage sockets 360 and 136 of the above embodiment can be applied to a case where the drainage pipes 390 and 390 are lead pipes. In this case, prepare an adapter that can be connected to the lead pipe separately, and connect the drain pipes 390, 139 and the drain sockets 360, 136 through this adapter. I just need.

In the above embodiment, the case where the drain pipe 390 rises from the floor surface FL is described as an example of floor drain. However, in the present invention, the drain pipe 390 is installed at the place where the flush toilet 310 is installed. It can also be applied to the case of wall drainage taken out of the wall. In general, flush toilets are called S-trap type, in which the end of the drainage channel is directed toward the floor, and P-trap type, in which the end of the drainage channel is directed toward the wall, in response to the different building conditions of each building. There are two types of variations. The distance from the end of the drainage channel to the wall surface may differ depending on the type of toilet, even for toilets with P-trap specifications. Also, in the case of wall drainage, the distance that the drain pipe is taken out of the standing pipe behind the wall differs for each installation location, as in the case of floor drainage. Therefore, if the connecting member that connects the drain pipe taken out of the wall and the end of the drainage channel of the P-trap toilet is configured to have a variable overall length, the connecting member can be shared. It is possible to improve the workability of the toilet room as a whole.

Further, in the above embodiment, the siphon jet toilet was described as an example, but the present invention can be applied to other types of toilets. For example, not only siphon-type toilets that cause a siphon action without flushing water from the jet holes, but also flush-type toilets that flush waste and accumulated water by the water force of the wash water without using the siphon action. Can also be applied. If the drainage channel of the flush toilet is bent from top to bottom, the drainage channel will be almost full when washing the toilet, which may cause a phenomenon similar to siphon operation. In such a case, if the drainage sockets 8360 and 1360 of the present embodiment are installed, the stored water RW and The stagnant point of the washing water can be adjusted as needed by changing the mounting position of the socket member in the drainage pipe, and the drainage pipes for the RW and washwater RW and 339 The suction force in the zero direction can be increased, and the cleaning ability can be further improved.

Further, in the above embodiment, the case where the present invention is applied to a flush toilet such as a siphon-jet toilet was described as an example.However, the present invention is grasped as a combination of the above flush toilet and other devices and members. You can also. For example, a sanitary washing device combined with a functional toilet seat that realizes various functions such as local washing and heating, a cabinet for storage, a trirectomy device combined with a hand washing device, a wall material as a structure in a toilet room, A system toilet system combining flooring and ceiling materials, etc. is conceivable.

Next, the 12th to 14th embodiments will be described.

FIG. 67 is an explanatory view showing a vertical cross section of a siphon-jet type flush toilet 410 according to a 12th embodiment of the present invention. The siphon-jet type flush toilet 410 ejects water from a jet outlet 422, which will be described later, with washing, to cause a siphon action.

As shown in FIG. 67, the flush toilet 4100 includes a ball section 420 for receiving waste. The peripheral wall of the ball portion 420 has a water-covered surface 4 23 that is in contact with the stored water RW even when the flush toilet 4 10 is not washed, and an exposed surface 4 that is not in contact with the stored water RW when the flush toilet 4 10 is not washed. Consists of 24.

A recess 426 at the bottom of the ball portion 420 has a jet outlet 422 almost opposite to the inlet 425 of the siphon trap line. The jet holes 422 are provided with a jet water supply hole 445 serving as a washing water inlet to the hole, and a jet water supply passage 424 curved so as to surround the ball portion 420 inside the toilet. Connected via 6. The washing water ejected from the jet outlets 422 will not cause energy loss due to the positional relationship between the outlets and the trap inlet, and will be applied to the siphon trap after the inlet 425. Get in. As a result, the pipeline can be filled at an early stage, and the siphon effect can be induced at an early stage. A flush water tank WT is installed behind the flush toilet 4100 to supply flush water to the bowl section 420 when flushing the toilet. The flush toilet 410 has a flush water supply hole 4440 through which evening flush water flows in through the water supply line SL, and a flush water supply passage 441 below the flush water flow path. I do. The washing water supply channel 44 1 serves as a space interposed between the jet water supply channel 4 46 for jetting the washing water to the ball portion and the lower end of the drain pipe of the washing water tank WT. Section a. Then, the cleaning water discharged from the drain pipe flows into the stagnant portion 441 a during cleaning, and the flowing cleaning water flows through the jet water supply hole 445 and the jet water supply channel 446. It is ejected from the vent hole 4 2 2. After the stagnant portion 4 41 a is full, the washing water in the stagnant portion flows out to the rim water supply channel 4 4 3 via the branch hole 4 42 above the stagnant portion, and the lower end of the rim portion 4 2 1 It is ejected from the rim ejection hole 4 4 4 formed in the rim.

Next, a discharge mechanism including a siphon trap will be described. As shown in the figure, the siphon trap has a connection passage 431 that curves obliquely upward from a suction opening 425 that opens into a recess 426 as a waste pool, and a connection passage 431 It is composed of a rising path 432 that extends in the bending direction and then curves in the lateral direction, and a descending path 433 that serves as a first descending pipe section that curves downward from the horizontal direction.

The descending path 433 has, at its distal end, an extended portion 433a with an enlarged pipe diameter and an end narrowed portion 433b with an opening area smaller than that of the extended portion. Therefore, this descending route 4 3 3 is composed of the extension 4 4

Since the washing water passing through 3 3b is temporarily retained, the siphon action is also induced in the descending passage 4 3 3 itself. This descending channel 4 33 is provided at the end of the toilet through a drainage socket 470 as a second downcomer made of resin, and the drainage pipe is set up from the toilet floor FL at the toilet installation location.

Connected to 490.

These channels are formed integrally with the porcelain flush toilet 410 by shaping the channel shape into a plaster mold or a resin mold. It is also possible to form the flow path with a member different from 0. For example, all or some of these flow paths may be formed of another member such as resin and connected to the suction port 425.

The drain socket 470 is located on the floor FL of the toilet and is fixed to the floor of the toilet with bolts and the like. And a conduit forming member 473 that forms a socket conduit 472 leading to 490. The conduit forming member 473 has a spiral recess 474 that spirally surrounds the socket conduit 472. In this case, the socket pipeline 472 has substantially the same diameter as the above-mentioned end narrowed portion 433b.

The socket body 471 has a descending channel fitting portion 471a into which the end of the descending channel 433 enters the upper end, and a drain pipe fitting portion into which the upper end of the drainage pipe 490 enters from below. 4 7 5 is provided. The drainage pipe fitting portion 475 positions the drainage socket 470 with respect to the drainage pipe 490 by fitting the drainage pipe 490. Since the end of the pipe forming member 473 is located below the upper end of the drain pipe 490, the washing water passing through the pipe forming member 473 is discharged from the upper end of the drain pipe 490. It is hard to leak.

Both the socket body 471 of the above-mentioned drainage socket 470 and the pipe forming body 4733 are resin molded products, and the flush toilet 4100 is specifically referred to as the downcomer 433. Although it is a separate body, it may be integrated with this descending route 4 3 3 (that is, a siphon trap). As described above, when integrating with the descending path 4 33, a pipe such as a socket pipe 4 72 is formed with a spiral recess with the end narrowed section 4 33 b interposed between the extension section 4 33 a. Along with 4 7 4, it may be connected to the descending route 4 3 3 when the toilet is manufactured. Also, the siphon trap of the flush toilet 4 10 does not have a siphon triggering mechanism such as the end throttle section 4 33 b, and the drainage socket 470 connected to the siphon trap is connected to the end throttle section 4 3 3 It is also possible to have a siphon inducing mechanism such as b, a socket conduit 472 and a conduit former 473. When the socket body 471 and the conduit forming body 473 are made into a resin molded product, it is the same as the drain pipe 490 Use of various resins such as ABS resin, PP (polypropylene), PE (polyethylene), PPS (polyphenylene sulfide), MA (acrylic), and POM (polyacetal) in addition to vinyl chloride resin Can be.

As shown in the figure, in the flush toilet 4 10 before the washing operation, the accumulated water RW is stored at the height of the normal water level line WL in the connection path 4 31, the ascending path 4 32 and the ball section 420. ing. The spilled water RW prevents the backflow of odor and the invasion of pests from the drainage mechanism to the ball section 420.

The pooled water RW has water that accumulates inside the ball section 420 up to the suction port 4 25 (hereinafter, this water is referred to as ball section pool water or sealed water) and the connection from the suction port 4 25 The water that accumulates in the channel 431 and the ascending channel 432 (hereinafter, this water is referred to as accumulated water in the channel), the lower part of the stagnant part 441a of the flush toilet 410, and the jet water supply channel 446 Water that accumulates in water (hereinafter, this water is referred to as jet water). As shown in Fig. 67, the accumulated water in the flow path is from the connection path 431 to the ascending path 431 of the sewage flow path composed of the connection path 431, the ascending path 432, and the descending path 433. The wastewater is collected only at one point between 32 and 2. The "sewage" means water that is dirty by mixing waste such as stool and urine or paper.

The height of the normal water level line WL is determined by the height of the weir 434, which is the highest position below the inner wall of the ascending road 432. Therefore, as shown in Fig. 67, the lower part of the stay part 441a of the flush toilet 410, the jet water supply hole 445, and the jet water supply channel 446 are located below the weir 434. For this reason, when the flush toilet 410 is at rest, the pool water is stored in the lower portion of the retaining section 4441a and the jet water supply channel 446 at the above-mentioned water level. If the height of the weir 4 3 4 is reduced, the water level of the stored water RW will also be lowered, and the amounts of the water in the ball, the water in the flow path, and the water in the jet will also be reduced.

A mechanism for discharging sewage and waste by the drainage mechanism configured as described above will be described. When the wash water is discharged from the wash water tank WT, the discharged wash water first flows into the retaining section 4 41 a, and the position energy Using the lugi as kinetic energy, the jet water in the jet water supply channel 446 is poured into the ball water (sealing water) in the ball portion 420. As a result, the jetting of the washing water toward the trap from the jet outlets 42 is started, and thereafter, the washing water itself is discharged with the above energy while the washing water is continuously discharged. It is continuously ejected from the jet outlet 4 2 2. In the early stage of the jetting operation, the staying portion 441 a is replaced with the flushing water, and after the completion of the replacement, the flushing water is gushing out from the rim ejection hole 444 through the branch hole 442. You.

When the washing water is ejected to the ball portion 420 in this manner, the water level of the ascending channel 432 rises, and the bent portion from the ascending channel 432 to the descending channel 433 (hereinafter referred to as a bent portion) Becomes full. Then, the washing water passes through the descending passage 4 33 3, and at the time of the passage, the washing water is temporarily stored in the extension portion 4 33 a at the end of the descending passage, and the trap pipe line is formed. Is filled with washing water, and a siphon tube is formed. Then, a pressure difference is generated between the washing water of the siphon tube and the stored water of the ball section 420, and a downward pulling force is generated. With this pulling force, the washing water (sewage) filled in the siphon trap (in the ascending channel 432 and the connecting channel 431) and the washing water (sewage) in the ball are discharged into the drain pipe 490 together with the dirt. It is led. Thus, a siphon effect is induced.

Next, the behavior of the wash water after the induction of the siphon action will be described. FIG. 68 is an explanatory diagram for explaining the passing behavior of the washing water in the siphon trap and the socket line 472.

The washing water that flows due to the induction of the siphoning effect tries to pass through the socket line 4 72 as it is via the extension 4 33 a as shown by the white arrow in Fig. 68 (a). Flow passes through socket line 4 7 2. At the same time, some of the washing water enters the spiral recess 474 surrounding the socket line 472 and is stored. Then, the washing water in the spiral recess 474 flows spirally down the spiral recess 474 as shown by the dotted line in the figure. Alternatively, the washing water in the spiral recess 4 7 4 It flows down from the opening of the place and joins the washing water in the white flow in the figure.

Wash water supply A predetermined amount of wash water from the WT ・ Washing of the wash water from the orifice almost completes, and at the end of the siphon, the amount of wash water that reaches the socket line 472 via the siphon trap decreases. . In this state, as shown in FIG. 68 (b), the flow rate of the flush water that is going to pass through the socket pipeline 472 as it is (hereinafter, this flush water is referred to as “pass flush water” for convenience) is Less. However, there is washing water in the spiral recess 474, and this washing water flows spirally along the spiral recess 474 or merges with the passing washing water. On the other hand, it becomes replenishment washing water. For this reason, the flow rate of the entire washing water passing in the middle or at the end of the socket line 472 is increased. Therefore, the area occupied by the washing water in the cross section of the socket pipe 472 is larger than that of the existing pipe without the spiral recess 474. Can be suppressed by the washing water existing in a large occupied area. As a result, the siphon can be maintained for a long time even at the end of the siphon where the flow rate decreases, and the suction efficiency of the water in the ball section at the end of the siphon and the reliability of suction and discharge of suspended solids can be improved. it can.

In addition, the supply of washing water to the passing washing water from the spiral recess 474 is performed in the spiral recess 474 of each stage. Therefore, the supply of washing water to the passing washing water is ensured, so that the siphon can be reliably maintained. For this reason, it is possible to further improve the reliability of improving the suction efficiency of the pooled water at the end of the siphon and the reliability of sucking and discharging suspended solids.

In addition, since the spiral recess 474 is provided immediately below the constricted portion 433b of the connection path 431, which induces the siphon, the washing water can be replenished near the location where the siphon action is induced. For this reason, it is possible to increase the reliability by ensuring that the siphon maintenance is more reliable.

In addition, since a part of the passing washing water is led to the spiral recess 474 and is used as supplementary washing water, no special water channel system for supplying washing water is required. Therefore, the total amount of flush water used for flushing the toilet is not increased, and Configuration can be simplified.

Further, since the spiral water flows in the spiral recess 474 in a spiral shape, the cleaning water swirls around the socket line 472. Therefore, the swirl water can also suppress air inflow from the side of the drain pipe 490, so that the suction efficiency at the end of the siphon is improved and the suspended solids are sucked. be able to.

In this embodiment, the socket conduit 472 is formed as a spiral recess 474 with a recess. However, a helical plate may be inserted and attached to the socket conduit 472. it can.

Next, a modification of the above embodiment will be described. FIG. 69 is an explanatory diagram illustrating a drainage socket 470 according to a modification. As shown in the figure, the drainage socket 470 of this modified example has an annular recess 474a that is skewed outward at an appropriate interval in the socket conduit 472. Then, a part of the passing washing water is temporarily stored in each annular recess 4 7 4 a. The washing water is supplied to the passing washing water by its own weight. For this reason, even in this modified example, the washing water is merged from the respective annular recesses 474a with the washing water passing through the socket conduit 472 as described above, so that the above-described effects are achieved. can do.

Next, another embodiment will be described. FIG. 70 is an explanatory diagram for explaining the drainage socket 1470 of the thirteenth embodiment. As shown in the figure, the drainage socket 1470 of this modified example has a socket main body 1471 for fixing the floor surface, and guides the passing washing water to the drainage pipe 490 in the interior thereof. Eccentrically provided with an upstream socket pipe 1472 and a pipe forming body 1473. The drainage socket 1470 has a step portion 1475 opposed to the lower end of the pipeline forming body 1473 that forms the upstream socket pipeline 1472. Above the part, a storage chamber 1476 surrounding the conduit forming body 14473 is provided. Both the upstream socket line 1472 and the downstream socket line 1474 have almost the same diameter as the end narrowed portion 433b.

The socket body 1 4 7 1 The descending passages 433 are fitted to each other and fixed to the floor surface, and the drainage pipes 490 are sealed with a sealing material 14477 located at the upper end thereof. Even in this drain socket 1470, the end of the downstream socket line 1474 is located below the upper end of the drain pipe 490, and the washing water is supplied from the upper end of the drain pipe 490. The leak is suppressed. The drain socket 1470 is also formed from the above-mentioned resin such as a vinyl chloride resin or an ABS resin, as described above.

The drain socket 1470 collides the washing water passing through the upstream socket line 1472 with the step 1475 as shown by the arrow in the figure, and changes its direction. To the downstream socket line 1 474. The upper part of this step 1 4 7 5 is expanded by the storage chamber 1 4 7 6, and in conjunction with the change in the flow direction at the step 1 4 7 5, the washing water is temporarily stored and the siphon effect is induced To contribute. Therefore, in the flush toilet 410 equipped with this drain socket 1470, siphon action is performed in two places: the end narrowing section 433b and the step section 1475 in the drain socket 1470. Therefore, it is possible to effectively improve the water suction power and the suction efficiency. Since the siphon action can be induced even with the drainage socket 1470, the flush toilet 4100 whose siphon trap end, that is, the downcomer 4 33 3 end line is a strat, is also used. The siphon effect can be induced by attaching the drain socket 1470.

The washing water behavior in the drainage socket 1470 is as follows. The washing water that has passed through the upstream socket line 147 2 due to the siphon action induction (passing washing water) is collided with the step portion 147 5, and as described above, the downstream socket line 147 Flow into 4. On the other hand, a part of the passing washing water flows into the storage chamber 1476 with the pressure induced by the siphon, that is, the head pressure (head difference) with the level of the stored water in the ball section 420. At this time, air exists in the storage room 14476, but this air is compressed by the above-mentioned pressure of the washing water, and accordingly, the washing water is stored in the storage room 14476 correspondingly. In other words, the storage chamber 14476 functions as a kind of accumulator. At the end of the siphon, the amount of wash water that passes through the upstream socket line 1472 and flows into the downstream socket line 1474 decreases, and the washwater that blocks the storage chamber 1476 at the lower end. The pressure also drops. In such a situation, the washing water stored in the storage room 1476 flows out of the storage room 14476 due to its own water pressure and own weight, and passes through the downstream socket line 1474. This leads to an increase in the flow rate of the cleaning water. Therefore, the area occupied by the washing water in the cross section of the downstream socket pipe 1474 is only the one that changes the direction of the washing water in the step section 1475 without the storage room 14476. Since it is wider than that, the air entry from the drain pipe 490 side can be suppressed by the washing water existing in a large occupied area. As a result, the same effects as those of the above-described embodiment can be achieved by the drainage socket 1470 of the thirteenth embodiment.

Further, the drainage socket 147 is provided at the end of the upstream socket line 1442 with washing water from the surrounding storage room 14476 to the periphery of the upstream socket line 14472. Replenish. Therefore, it is possible to easily increase the flow rate through the supply of the washing water.

In the drainage socket 1470 of the thirteenth embodiment, the storage room 14476 surrounding the upstream socket line 14472 was used, but one side of the upstream socket line 14472 was used. It can also be deformed so as to form. FIG. 71 is an explanatory diagram for describing a drainage socket 1470A of this modified example. The drain socket 1470A has a projection 1778 near the end of the upstream socket line 1472, and a storage chamber 14476 on the side facing the projection 1778. . In this drain socket 1470A, as shown by the arrow in the figure, the passing flush water that collides with the projection 1780 and changes its direction enters the storage chamber 1476. Therefore, even with the drainage socket 1470A of this modification, washing water can be supplied from the storage chamber 14476 in the same manner as in the above-described thirteenth embodiment.

Next, a description will be given of a 14th embodiment. FIG. 72 is an explanatory diagram for describing the drainage socket 2470 of the 14th embodiment. As shown In addition, the drainage socket 2470 of this modified example has a socket main body 2471 for fixing the floor surface, and inside the drainage socket 2410 for guiding the washing water passing therethrough to the drainage pipe 490. A socket pipeline 2 4 7 2 is provided. Then, the drainage socket 2470 has a throttle mechanism capable of narrowing and adjusting the pipe diameter of the socket pipe 2472. The throttle mechanism includes a pipeline restricting member 2473 which is arranged opposite to the socket pipeline 2472, an actuator 2474 which moves the pipe into and out of the pipeline, and an actuator which is not shown. Consists of a control device. The pipe restricting member 2 473 is made of a highly water-resistant and durable elastic material such as rubber and elastomer, and is formed on the pipe wall 247 5 around the socket pipe 2 472. It is fixed watertight. In response to a command from the control device, the actuator 24774 turns the pipe restricting member 2473 into the pipe and protrudes, or draws it toward the pipe wall. The actuator control unit determines the end of the siphon based on the elapsed time from the start of flushing the toilet, the pressure change in the socket line 2472, and the like, and according to the result, the actuator unit. Is controlled as follows.

When the toilet flushing is started by operating the handle or button (not shown), the actuator control unit issues a forward command to the actuator unit 274 to drive it, and as shown in FIG. Restrictive member 2 4 7 3 squeezes into pipeline. As a result, the pipeline of the socket pipeline 2472 is narrowed, and during this time, the passage of the washing water of the socket pipeline 2472 is restricted. Even under these restrictions, siphon action is induced at the end narrowed section 433b of the descending path 433, and washing water passes through the socket line 2472, so there is no particular problem. Suction of water and dirt is performed. Even if the pipeline restricting member 2473 is protruding in this way, the pipeline between them is designed so as not to hinder the conveyance of filth. As shown in the drawing, the state in which the pipe line restricting member 2473 is protruding can also be used as the origin position of the throttle mechanism. In this case, the above-mentioned actuation overnight drive is not necessary.

Now, the actuator control unit ends the recirculation due to the above elapsed time. When it is determined that the period is approaching, the actuator control unit issues a retreat command to the actuator 247 to drive it, and draws the pipeline limiting member 247 to the pipeline wall side. As a result, the pipeline of the socket pipeline 2 472 is expanded from the previous state, so that the restriction of the passage of the washing water due to the narrowing of the pipeline is eased, and the socket pipeline 247 downstream of the throttle mechanism is reduced. Pass 2 Wash water is increased. Therefore, at the end of the siphon, the occupied area of the flush water in the socket line 2472 downstream of the throttle mechanism is increased, so that the above-described siphon is maintained and the efficiency of suction of the water in the ball portion is improved. Thus, the same effects as in the above embodiments can be obtained.

The above-mentioned 12th to 14th embodiments can be modified as follows.

For example, in the above embodiment, the low tank type tank connected to the toilet was used as the flush water tank, but a tank other than the low tank type tank, for example, connected to the toilet via a flush pipe and installed on the wall of the toilet, etc. Alternatively, a cornered or flat tank may be used. In this case, it is also possible to set the washing water tank at a high position and use it as a high tank.

Further, the case where the present invention is applied to a siphon-jet flush toilet 410 or a siphon toilet has been described as an example, but it can be understood as an invention in which the above-mentioned toilet and other members of the apparatus are combined. For example, a sanitary washing device combined with a functional toilet seat that realizes various functions such as local washing and heating, a toilet cabinet combined with a hand washing device, a wall material and a floor material as a structure in a toilet room And a system toilet device combining ceiling materials.

Next, a fifteenth embodiment will be described.

FIG. 73 is an explanatory view showing a vertical section of a siphon-jet type flush toilet 610 according to a fifteenth embodiment of the present invention, and FIG. 74 is an explanatory view showing an upper surface of the flush toilet 610. is there. The flush toilet 610 spouts water from a jet outlet 622 described later in accordance with the washing, thereby causing a siphon action. Hereinafter, each part of the flush toilet 610 will be described with reference to FIGS. 73 and 74.

The flush toilet 610 includes a ceramic toilet body 611, a resin drainage socket 670, a washing water tank, and the like. The drainage socket 670 connects the outlet of the drainage pipe 630 of the toilet body 611 to the drainage pipe P projecting from the floor FL.

The toilet body 6 11 has a ball section 6 20 for receiving filth. The peripheral wall of the ball section 62 has a water-covered surface 623 that contacts the stored water RW even when the flush toilet 610 is not washed, and an exposed wall that does not contact the stored water RW when the flush toilet 610 is not washed. It consists of face 6 2 4.

As shown in FIG. 74, the jet outlet 62 2 is connected to the jet water feed port 645 which is a water inlet via a jet water supply channel 646 formed so as to curve the inside of the toilet. It is connected. As shown in FIG. 73, the jet holes 6 22 are provided at positions substantially opposite to the discharge ports 6 25 across the recess 6 26, and the energy of the washing water is supplied to the discharge ports. It is transmitted to the discharge mechanism after 6 25 without waste. Therefore, it is possible to cause the siphon effect early.

Inside the flush toilet 610, a water supply mechanism for supplying water to the ball portion 620 and a discharge mechanism for discharging the dirt in the ball portion 620 toward the drain pipe P are provided. Is provided.

First, the water supply mechanism will be described. A flush water supply hole 640, which is a hole for connecting a water supply pipe SL of the flush water tank WT, is provided behind the flush toilet 6100. A flush water supply passage 641, which is a flow path of the flush water from the flush water tank WT, is provided inside the flush toilet 610 going from the flush water supply hole 64 to the ball section 62. ing. The washing water supply passage 641 is a space interposed between the jetting water passage 646 for jetting the washing water to the ball portion 62 and the lower end of the water supply pipe of the washing water tank WT. Section 6 4 1a is sectioned. The washing water supplied from the water supply pipe SL at the time of washing flows into the stagnant portion 641a. The washed water thus discharged flows out through a jet water supply channel 646 and a branch hole 640 described later to a lithium water supply channel 644.

In other words, the water stored in the tank (wash water) urged by the free fall is supplied to the wash water supply channel 641. For this reason, the stagnant portion 641a, in which the washing water supply channel 641 is formed diagonally downward, is filled with water after the start of washing, and a part of the washing water flows from the branch hole 642 to the rim supply channel 6 Supplied to 3. The cleaning water supplied to the rim water supply channel 643 is discharged from a drain hole 644 provided on the rear side of the rim portion 621 (see FIG. 74).

As shown in Fig. 74, on the back side of the rim 6 21, a large hole 6 4 4 a with a diameter of 7 mm, a medium hole 6 4 4 b with a diameter of 4 mm, and a small hole 6 4 4 c with a diameter of 3 mm There are five types of drain holes 644, which are approximately rectangular long holes 644d and 44e. The drain hole 644 is formed when the rim portion 621 is formed. Of course, a distributor having a drain hole is mounted on the back side of the rim portion 621. There may be.

The flush water urged in the forward direction of the flush toilet 610 and supplied to the left and right limb water supply channels 643 corresponds to the opening diameter of the water discharge hole 6444 ゃ the urging force of the flush water. It is dispensed and discharged from each of the holes 644 a to 644 e. At this time, water with a large urging force is supplied from the long hole 644 d formed on the back side of the right rear portion 621, which is located near the branch hole 642, slightly in front of the toilet. The liquid is discharged toward the left exposed surface 6 2 4. In addition, the flush water flowing clockwise through the Lim water supply passage 643 from the long hole 644e formed in the front right side of the flush toilet 610 A large amount is discharged toward the rear exposed surface 6 2 4. The cleaning water discharged from the long holes 644 d and 644 e becomes the mainstream, and a clockwise turning force is applied to the cleaning water discharged from the water discharging hole 644. This turning force is transmitted to the pool water RW in the ball section 62. As a result, the water in the ball portion 62 becomes a clockwise swirling flow.

In addition, the washing water that has reached the retaining portion 641a enters a jet water supply hole 645, which is a hole provided on a side wall of the retaining portion 641a. With this approach As a result, flush water is supplied to the jet water supply channel 6 4 6. The washing water supplied to the jet water supply channel 646 is jetted from the jet jet port 622. Then, when the stagnant portion 641 a is replaced with washing water, washing water is guided from the branch hole 642 to the rim water supply channel 643, and the washing water is discharged from the water discharging hole 644 of the rim. Discharged.

Next, the discharge mechanism will be described. As shown in Fig. 73, at the end of the discharge port 625 formed inside the recess 626 as a waste pool, a drainage pipe 6330 as a flow path for water and dirt is placed on the toilet body. It is integrally formed with 6 1 1. The drainage pipe 630 extends from the discharge port 625 in the diagonally upward direction to the connecting path 633 and the connecting path 633, and then rises in the horizontal direction. 32, a descending path 6 33 that curves downward from the lateral direction is formed, respectively. The descending route 633 is connected to a drain pipe P which is set up from a toilet floor surface FL at a toilet installation location via a resin drainage socket 670 at its end.

FIG. 75 is an enlarged sectional view showing the vicinity of the drainage socket 670 of FIG. In FIG. 75, the drainage socket 670 is made of resin such that the toilet connection part 671, the connecting pipe part 673, the drainage pipe connection part 674, and the socket fixing part 6778 are made of resin. Lie molding.

That is, the toilet connection section 671 is connected to the drainage pipe 630 by fitting the lower end of the descending path 633 of the drainage pipe 630 inside. A connecting pipe section 673 extends below the toilet connecting section 671, and is positioned on the drain pipe P by fitting the connecting pipe section 673 to the drain pipe P. Further, a drainage pipe connection portion 674 is formed on the downstream side of the toilet connection portion 671 and on the inner peripheral side of the connection pipe portion 673. The drainage pipe connecting portion 674 is arranged concentrically with the connecting pipe portion 673, and has a lower end portion serving as an outlet cylinder portion 675 having an outlet 675a. The outflow cylinder 675 is inserted into a drain pipe P connected to a sewer pipe to prevent the washing water from leaking to the outside. A socket fixing portion 6780 is formed around the outer periphery of the drainage socket 670. The socket fixing part 6 7 8 is This is a part for fixing the socket 670 to the floor FL.It is formed almost as a pedestal in the horizontal direction from the outer periphery of the lower end of the drainage socket 670, and is fastened to the floor FL with screws (not shown). As a result, the drainage socket 670 is fixed to the floor surface FL.

In addition, the drainage socket 670 is provided with washing water retaining means 680 for inducing a siphon and a delay means 690 for delaying outflow of the washing water at the upper part thereof. FIG. 76 is an enlarged perspective view showing the vicinity of the washing water retaining means 680 by breaking the drainage socket 670. In FIG. 76, the washing water retaining means 680 is provided with an annular projection 681 (an exfoliating projection) projecting annularly from the pipe wall toward the center. The flow path is 682, and the upper surface is an inclined surface 683 with an obtuse angle. The length of the annular projection 681 in the horizontal direction from the inner pipe wall is L1. The washing water retaining means 680 is formed by changing the direction of the washing water flowing along the inclined surface 683, because the throttle flow path 682 is narrower than the upstream flow path. And act to cause the siphon to occur quickly.

Further, below the annular projection 681, a delay means 6900 is provided. The delay means 690 has a guide ridge 691 (a convex portion for delay). The guide ridges 691 are projecting in a continuous spiral shape, and the gap between them is a guide groove 692, and the center thereof is a flow path 693. The length 2 of the guide ridge 691 in the horizontal direction from the inner pipe wall is shorter than the length L1 of the annular protrusion 681. In other words, since the annular protrusion 681 is larger than the guide protrusion 691 toward the center, the annular protrusion 681 is like an eave covering the guide protrusion 691. . Therefore, the delay means 690 allows the washing water to flow to the flow passage 693 when the washing water does not flow into the guide ridge 691, while the washing means flows when the washing water flows into the guide ridge 691. However, a part of the washing water is guided to the guide groove 692, and is configured to flow downward spirally while guiding the guide.

In the flush toilet 610 constructed in this way, sewage and waste are discharged. The cleaning process to be performed will be described. Before the start of cleaning in the cleaning process, as shown in Fig. 73, the pool water RW supplied in the previous cleaning process

Stored in 20. The accumulated water RW contains water that accumulates inside the ball section 62 up to the discharge port 625 (hereinafter, this water is referred to as sealed water), and a connection path 6 3 after the discharge outlet 625. 1 and the water that accumulates in the ascending channel 6 32 (hereinafter, this water is referred to as accumulated water in the flow path), and the water that accumulates in the lower part of the retaining portion 6 41 a of the flush toilet 6 10 and the jet water supply channel 6 4 6 (Hereinafter, this water will be referred to as “Zeta reservoir”). The height of the water line WL is usually

It is determined by the height of the weir 34, which is the highest position below the inner wall of 32. Therefore, before the flushing starts, the lower part of the staying part 641 a of the flush toilet 610, the jet water supply hole 645 and the jet water supply passage 646 are located below the weir 34, so that the flush water is used. Is filled with

In this state, when the washing water is supplied from the washing water tank WT, the water supply washing water first flows into the stagnating portion 641a, thereby discharging the jetted water in the lit water supply channel 646. Then, the gas is jetted into the drainage pipe 630 through the jetting hole 622. On the other hand, when the washing water supplied to the retaining portion 641a is filled up to the upper position, it is ejected from the draining hole 644 through the branch hole 642.

When the washing water is ejected to the ball portion 62 in this way, the water level of the rising path 632 rises, and the bent portion from the rising path 632 to the descending path 6333 becomes full. Then, the washing water passes through the descending path 633, and when the washing water is temporarily stored in the washing water retaining means 6800, the washing water and the accumulated water in the pole section 620 A pressure difference is generated between them, and a downward pulling force is generated. With this pulling-in force, the washing water filled in the ascending passage 632 and the connecting passage 631, and the washing water in the ball portion 62 are immediately led to the drain pipe P together with the dirt. In this way, the siphon action is induced, and the washing water (waste water) and the waste in the ball unit 62 are quickly discharged to the outside through the drain passage.

Next, the washing water that has passed through the washing water retaining means 680 becomes the delay means 690 Now, the operation of the delay means 690 will be described. Fig. 77 is an explanatory diagram illustrating the temporal change in the amount of washing water flowing out of the drain during the washing process, Fig. 78 is an explanatory diagram illustrating the initial or middle stage of the washing process, and Fig. 79 is It is explanatory drawing explaining the state of the last stage of a washing | cleaning process. In the washing process in this embodiment, the action of the washing water by the delay means 690 differs between the initial stage, the middle stage, and the end stage.

In the initial stage (time t1 to t2) and the middle stage (time t2 to t3) of the washing process, the washing water that has passed through the washing water retaining means 680 goes to the delay means 690. At this time, the washing water has a high water level in the ball section 62 and a large head pressure, so it is squeezed by the washing water retaining means 680 at a high flow rate, and becomes the delay means 690. Heading. That is, as shown in FIG. 78, the flow path 682 of the washing water retaining means 680 has a smaller flow path diameter than the flow path 693 of the delay means 690, so that the annular projection 6 8 1 shields the guide ridge 691 like an eaves, and hardly directs washing water to the guide ridge 691 of the delay means 6900. In other words, in the initial and middle stages of the cleaning process, the flow rate of the cleaning water is high, so that the delay means 690 flows the cleaning water as it is and does not hinder drainage.

At the end of the cleaning process (time t3 to t5), when the drainage amount of the cleaning water exceeds the peak value, the water pressure in the head sharply decreases as the water volume decreases, The aimed flow rate decreases. For this reason, as shown in Fig. 79, the washing water has a circumferential force that is relatively larger than a downward force, and is directed toward the inner pipe wall. It flows downward while being guided spirally by 6 9 1. At this time, since the washing water flows through the spiral guide groove 692, the time is longer than when the washing water falls vertically. In other words, at the end of the washing process, the washing water has a longer flow resistance due to the delay means 690, and the time until it is discharged becomes longer. If this is shown in Fig. 77, the flow rate changes from the flow rate indicated by the two-dot chain line to the change in flow rate indicated by the solid line as in the past. As described above, the time from the time t4 to the time t5 until the discharge of the washing water at the end of the washing is completed. To become longer.

Therefore, the washing water discharged from the drainage pipe 630 quickly discharges waste in the early or middle stages of the high-speed cleaning process, while being delayed at the end of the low-speed cleaning process. And the time it takes to be discharged is longer. Therefore, it is possible to reliably discharge the late-discharged waste such as the dirt floating in the ball portion 62 from the ball portion 62. Since the peak value is only slightly suppressed, the power to discharge waste is not reduced.

Further, since the washing water retaining means 680 and the delay means 690 are formed in the drainage socket 670 and are formed separately from the toilet body 611, they have complicated shapes. Can also be easily formed.

The above-described fifteenth embodiment can be modified, for example, as follows.

(1) The washing water staying means 680 and the delaying means 690 may be formed integrally with a porcelain flush toilet by molding the flow path into a plaster mold or a resin mold.

(2) In the above embodiment, the delay means is a continuous spiral guide ridge. However, the present invention is not limited to this.A part of the delay means may be a spiral notch, or the delay means may protrude in multiple stages in the horizontal direction. It may be a projection, and its shape is not particularly limited. Industrial applications

INDUSTRIAL APPLICABILITY The flush toilet and its drainage device according to the present invention and the toilet having the same can be used to induce an efficient siphon action for discharging dirt from the ball portion.
