Abstract

Promote the low silhouette of the toilet and increase the versatility of installing the toilet. The first liquor S1 is flushed from the base portion first water discharge hole 41 and the base portion second water discharge hole 42 at the rear side of the toilet. It is formed at the confluence of numbers. The first main stream S1 becomes a flow having accurate directionality and strong water washing due to the confluence, and the flowing water RS is inclined from the left side of the toilet bowl in a planar view and merges toward the right front side. The washing water discharged from the left central bubbling hole 43 circulates along the upper circumferential wall at the bottom of the rim, but the discharge trajectory is corrected by the discharge washing water from the rim joining in the meantime, and the flow has the correct directionality and strong water washing by the confluence. It becomes the 2nd liquor of S2. The second liquor S2 is inclined from the right front side of the toilet bowl in plan view with respect to the running water RS, and merges toward the left rear side. The first liquor S1 and the second liquor S2 are substantially parallel along the long sides with respect to the flowing water RS and merge in the same rotational direction. As a result, the swirl flow can be surely discharged to the flowing water RS, and the swing is promoted.

Description

Toilet and its manufacturing method {TOILET AND METHOD OF MANUFACTURING THE SAME}

In these various types of toilets, the performance of efficiently discharging dirt together with the running water and the water supply washing water of the toilet bowl part, and reducing the total amount of the water supply washing water is required. In order to meet these demands, various techniques have been proposed, which are roughly classified into the following techniques. The first method is a method in which the feed water washing water is joined to the flowing water to cause the turning, and the dirt flow is pushed into the trap by the turning flow. The second method is a method of sucking dirt together with running water and washing water by the siphon action.

In employing such a method, it is common to provide a lymph channel through the upper circumference of the toilet bowl and discharge the feed water washing water from the discharge holes provided in the channel to the flowing water. In addition, the generation of the siphon action is pushed into the trap of the flowing water by such a swirl flow, or pushing of the flowing water is carried out by dropping by the simple washing aberration to the some discharge hole provided in the rim channel.

However, the method employed in the conventional toilet is not enough, and problems as described below are pointed out.

In recent years, the request for the reduction of the total amount of the washing water (the total amount of the water supply washing water) used for the washing of the dirt is higher, and it is common to make the total amount of the washing water into a small amount of about 6 liters. Since such a small amount of total flow causes the generation of the above-mentioned swirl flow and the generation of siphon action, it is fixed to supply the washing water with high water washing, that is, a large flow rate, and the washing water is discharged at a flow rate of about 100 to 150 liters. It is widely used to flow into the toilet bowl.

As such, high water washing is required, and in a toilet for discharging the water supply washing water from the washing water tank, it is necessary to ensure the head pressure by increasing the water surface of the storage washing water in the tank to ensure high water washing. For this reason, since a washing water tank cannot be made high, the low silhouette of the toilet is damaged by the design restriction in the one-piece of a tank and a toilet.

In addition, in a toilet in which the washing water of a primary side pipe such as a water pipe is directly supplied to a toilet, water supply is required at a high primary water supply pressure when the water washing of the washing water joining the flowing water is increased. On the other hand, when the washing water is combined with the flowing water with high water to generate the swirl flow, the high water washing is good for the generation of the swirl flow, but since the confluence of the washing water is continued at the high generation, the chaos of the turning useless for the swirl flow is created. There was something that caused it. As a result, the energy (washing water) of the washing water may not be necessary for the continuous generation of the swirling flow, and there is a concern that the efficiency of pushing the washing water into the trap based on the swirling flow is reduced. In addition, in the region where the primary side water supply pressure is low, the washing water wash by the water supply is also low, and the efficiency of pushing by the swirl flow is also low. As a result, it did not proceed to the low water supply area or the country of the swivel-type toilet.

However, in the toilet using the siphon action, the occurrence and continuation of the siphon action is indispensable. Accordingly, it is important to prevent the inflow of the feed water washing water into the flow channel by discharging all the air in the pipeline of the siphon trap to the outside of the trap at the initial stage of the flow. For this reason, in any case of the swirl flow method or the drop-in method describing the flushing water discharge to the toilet bowl part, if the flushing water flows into the flow channel with high water washing, the outside discharge of the air in the pipeline and all the waters are cleaned in a short period of time. It can be achieved by quantity, so it is perfect for personalization. On the other hand, when the flow of washing water is low, the air is discharged and the water in the pipe is required for a long time to supply the washing water, so a large amount of washing water needs to be used. It was not. Against this background, even in a toilet using a siphon trap, the design water restriction and the water supply pressure restriction (advanced water pressure) were primarily restricted by the height of the washing water tank for securing the head pressure.

On the other hand, in the existing siphon trap type toilet, various designs have been devised for the early generation of the siphon action, and many techniques are used to make the siphon trap line early. In other words, in the toilet bowl, the flushing water flows to the toilet bowl with a large flow rate of about 90 to 100 liters, and in some cases, about 150 liters at high water, and pushes the air in the siphon trap line out of the pipeline by the force of this water. Fill all of with washing water at an early time.

In the existing siphon trap type toilets, the premise of the duct flow by washing water supply at the high flow rate is required to cope with the inflow and passage of the washing water at the high flow rate. Various techniques have been proposed for the siphon trap pipeline trajectory leading to the pipeline. These techniques do not give particular consideration to the improvement of the shaping | molding degree of the siphon trap pipeline at the time of manufacture, and the pipe shape of an individual part. However, in recent years, as the demand for the reduction of the total amount of washing water (water supply and washing water amount) used for washing of the dirt is higher, it is necessary to devise an individual shape or an improvement in the accuracy of the siphon trap pipe, but it is not sufficient. Current status

Specifically, it is as follows.

As described above, when the flushing water flows into the bowl bowl at a high flow rate, the curved top portion having the top bank and the downcoming pipe portion continuously forming the siphon trap pipe line, which defines the water level in the rising pipe portion, does not fail to generate the siphon. . For this reason, in the manufacture of toilet bowls, slips are deposited in a shape having an iron shape suitable for the inner circumferential wall shape of the toilet bowl part, and the mold close side of the completed casting is used as the inner wall of the toilet bowl part. The inner wall of the ascending pipe portion. Since the opposite side of this casting was formed so that it might not contact the die surface of a metal mold | die, the unevenness | corrugation was completed in some cases. The same applies to the curved top part. Particularly, in this curved top part, since the top bank is inside the pipe, the top part has to be in the shape of steel in the pipe by returning the pipe, and the shape thereof cannot be devised. In other words, even if the concave-convex wall is completed, the existing toilet has a premise that the water supply of the washing water at a large flow rate is premised, and this unevenness does not cause a problem in the passage of the washing water to the pipeline. In addition, since the air in the duct is temporarily discharged from the existing toilet by the washing water at a large flow rate, the top bank is preferably iron-shaped by the return of the duct, and its shape has never been a problem. In the early stages, it is not enough to consider the improvement of molding precision and the shape of each pipe line.

By the way, when providing such a siphon trap type | mold toilet, it is necessary to connect the drain port of the toilet exterior and a siphon trap line. Since the drainage method is not uniform and is regulated by the municipality, the government, or a group, the connection between the drainage port outside the toilet and the siphon trap line is called a different material than the ceramic toilet, so-called socket. Other parts are used.

For example, the rough-in, which means the distance from the toilet wall to the drainage center, is determined by country or region. Different rough ins result in different distances between the rear end of the toilet and the drain. Since the siphon trap paths are almost the same in the toilet bowl, it is necessary to select and use the above-mentioned sockets with the same bend depending on the roughness difference in the toilet bowl installation. It is preferable to change the end position of the siphon trap pipe line in the ceramic toilet bowl according to the rough in to eliminate such troubles, but only the part of the mold (body mold) increases because the toilet body is manufactured. This results in an increase in mold manufacturing cost or mold management cost. For this reason, the reality is that it is necessary to cope with the above socket selection.

An object of the present invention is to improve the versatility of the toilet and the promotion of the low silhouette (silhouette) of the toilet in order to solve the above problems.

In addition, in the siphon trap type toilet bowl, the purpose of the present invention is to increase the diversity of the siphon trap pipe shape or increase the suitability of the drainage specification to the ceramic toilet bowl itself.

The present invention relates to a toilet that discharges water supplied washing water to a toilet bowl part for cleaning the toilet, and a method of manufacturing a toilet having a siphon trap pipe in such a toilet.

It is also.

In order to solve at least some of these problems, the first toilet of the present invention discharges the water supplied from the upper part of the toilet bowl part, and in the toilet which generates swirl flow in the flowing water stored in the toilet bowl part, the toilet bowl is provided. A raceway for guiding the washing water to the upper circumference of the toilet bowl portion; the raceway includes a discharge portion for discharging the water supply washing water to combine the two main streams and discharging the water into the flowing water; The washing water is discharged by adopting a confluence of the flowing water to join the flowing water so that the flowing water flows into the flowing water almost in parallel with the flowing water on the toilet horizontal plane, while causing the swirling flow in the same rotational direction to the flowing water. Characterized in that.

In the first toilet of the present invention having the above constitution, the confluence of the two main streams into the flowing water causes the confluence of these main streams to flow in parallel with the flowing water in the horizontal direction of the toilet, turning in the same rotational direction to the flowing water. Let Ryu happen. Since each liquor having such a flow-join relationship joins the flow, the liquor of each other does not cause the disruption of the swirl flow generation. This makes it possible to reliably induce swirl flow in the running water. Since the swirl flow generated by the mainstream of each other is related to the confluence of the parallel and the same rotational direction, the rotational flow of the swirl flow is promoted without disturbing the swing direction of the swirl flow. This can increase the efficiency of pushing the flowing water due to the swirl flow. Moreover, since this situation occurs even when the flow rates of the two washing water liquors are low, the performance of at least the washing water being pushed in by rotation is maintained to generate the two washing water liquors. As a result, it is possible to achieve the discharge of the washing water at a small flow rate and to bring about a reduction in the total amount of the washing water.

With such a small flow rate, the amount of washing water discharge and the total amount of washing water can be made compatible, and the head pressure can be reduced when the washing water supplied for the production of liquor is made from the washing water tank. The wash water tank can be lowered. Therefore, the design of the whole toilet including a washing water tank can be improved, and the low silhouette of the toilet can be aimed at.

In addition, when the wash water feed water from the primary side pipe is used for the washing water supplied for the mainstream generation, since the swirl flow required for the washing can be generated by the discharge of the washing water at a low flow rate, the primary side piping area of the low water supply pressure You can also respond. Therefore, the toilet of the present invention can be installed even in a region where the primary water supply pressure is low due to the water supply situation. For this reason, the versatility to the installation place becomes high, and the spread of the toilet to the low water region and the country which employs the swirl flow system as in the present invention can be promoted. In addition, the toilet of the present invention can be easily applied and installed by providing a pressure reducing valve in a country or region where high water pressure is required due to legal regulations.

Moreover, since it is not necessary to cause the washing water discharge at the high water washing based on the large flow rate, the generation of sound can be suppressed by the washing water discharge or the confluence of the washing water into the water flow path, so that the quietness in the toilet bowl cleaning can be improved. In addition, insoluble water splashing due to the discharge of the washing water under high water washing can be suppressed.

The flowing water confluence of the two washing water liquors with the above flowing water may be caused to occur at the long portions of the flowing surface contours of the flowing water, respectively. In this case, in the case of flowing water of each liquor, it is easy to attach and preferable only when aiming in a flowing direction.

The 1st toilet bowl of this invention which has the said structure can employ | adopt the following various forms.

That is, the discharge portion of the raceway discharges the washing water flowed into the raceway toward the front of the toilet inclined with respect to the flowing water from above, and the first discharge portion for generating a first washing water liquor which is one direction of the two washing water liquor; ,

The washing water discharged from the raceway is discharged from the same side with respect to the central axis dividing the first discharge portion and the toilet left and right, and the washing water rotates periodically along the ball surface at the toilet bowl surface above the flowing water surface. A second discharge unit generating a flow of

Joining the flow of the washing water of the second discharge portion and correcting the flow of the washing water of the second discharge portion, and the second washing of the corrected second discharge portion of the washing water flow in the other direction of the two washing water mainstream It has a 3rd discharge part made into several mainstream.

In this case, since the second washing water liquor can be passed through the confluence of the flow of the washing water (water flow), the confluence of the water streams can provide accurate directivity and strong water washing. Therefore, since the trajectory of the flow of the second washing water main stream can be stabilized, the flow of the main stream can be reliably almost parallel and can be led in the same rotation direction. For this reason, it is possible to increase the reliability of the small amount of the total amount of the washing water that has passed through the washing water discharge at the small flow rate at the time of discharging the washing water for generating the first and second washing water liquors.

The first discharging unit discharges the washing water delivered to the raceway from a plurality of discharge holes formed in the raceway, and joins the washing water streams from the discharge holes to cause the first washing water mainstream.

This makes it possible to stabilize the trajectory of the flow even in the first washing water liquor, and furthermore, since a strong flow occurs in the confluence, the flow of the washing water at the small flow rate and the total amount of washing water in addition to stabilizing the trajectory of the second washing water liquor. It is possible to increase the reliability of the small amount.

In addition, the third discharge portion discharges the washing water guided to the raceway toward the flowing water from the front side of the toilet bowl, and joins the washing water flow of the second discharge portion, the flow of the second discharge portion washing water A fourth discharge portion for correcting a direction to the flowing water surface side;

Flow of washing water guided into the raceway is discharged from the opposite side to the first discharge portion with respect to the central axis dividing the toilet bowl left and right and corrected in the washing water from the fourth discharge portion. And the flow direction is corrected toward the flowing water surface, and after the correction, the flow of the washing water of the second discharge portion is the second washing water liquor, and has the flow of water flowing into the first washing water liquor. And a fifth discharge portion joining the flowing water.

In this case, the fifth discharge unit discharges the washing water so as to correspond to the flow of the washing water from the second discharge unit, joins the discharged washing water with the flow of the washing water in the second discharge unit, and the flow of the washing water in the second discharge unit. Can be brought into substantially parallel with the first rinse water liquor and joined to the running water in the same rotational direction.

In this case, since the calibration of the second washing water liquor is performed from each side of the first washing water liquor from the front side of the toilet, the trajectory of the second washing water liquor after the calibration is more stabilized, and is substantially parallel and the same rotation of the mutual liquors. The reliability of the total amount of the washing water can be further improved by improving the reliability of joining in the direction.

In addition, the raceway is provided with a sub-discharge unit for discharging the washing water guided to the raceway along the surface of the toilet bowl part, separate from the first to fifth discharge unit, including the discharge of the washing water from the sub-discharge unit The washing water flows over almost the entire surface of the toilet bowl surface.

In this way, the washing water can spread widely over the entire surface of the toilet bowl. Therefore, it is adhered to the surface of the ball part, so that paper or dirt can be reliably put in the running water, thereby improving the cleanliness of the ball surface.

Further, the toilet bowl part receives the first washing water liquor and guides the turning, and further defines a turning situation of the washing water after the first washing water liquor joins the running water. Wow,

A second ball circumferential wall portion for receiving the second washing water liquor to guide the turning and joining the second washing water liquor to the running water and defining the turning situation of the washing water.

This allows the first and second washing water liquors to have a more stable flow trajectory, and as a result, the two main streams of water can be more reliably maintained in parallel and in the same rotational direction as described above. It is possible to further improve the reliability of reducing the total amount of water.

In addition, the first and second ball circumferential walls have a difference in the washing water turning situation after water flow joining, so that one ball circumferential wall increases the turning lead in the flow depth direction, and the other ball circumferential wall makes the lead smaller in the turning. In this case, the second ball circumferential wall portion can enlarge the lead of the turning of the second washing water liquor, and the first ball circumferential wall portion can reduce the lead of the turning of the first washing water liquor.

In this way, it is possible to improve the pushing performance of the turn-based flowing water in the large swirl flow where the lead is large, and the lead can collect the dirt in the small swirl flow and send it to the large swirl flow to discharge the dirt. Do. Therefore, even if the washing water is produced at a low flow rate, the pushing performance can be maintained. In other words, even when the total amount of the washing water is reduced while discharging the washing water at the lower flow rate, the pushing performance by turning can be maintained, and the ability to discharge the dirt by the pushing (the toilet washing ability) can be reliably exhibited. have.

In addition, since the toilet bowl has a bottom shape, the turning radius of the swirl flow toward the trap opening of the bowl bottom gradually decreases, and the momentum of the swirl flow increases. For this reason, the performance of pushing in by the swirl flow is also improved.

In the case of the ball circumferential wall portion which makes a difference in the lead as described above, the first ball circumferential wall portion is formed so as to surround the flowing water to the side facing the trap opened at the bottom of the toilet bowl portion, and to surround the first washing water. In the guide shelf part which catches this, it can be set as having the said guide shelf part which causes the small turn situation of the said turning lead to the said 1st wash water liquor in the height position which is substantially corresponded with the flow surface of the said flowing water.

Further, in a location where the second ball circumferential wall portion receives the second washing water liquor and joins it to the running water, a large turning situation of the turning lead is caused in the vertical direction of the running water so as to cause the second washing water liquor. The inclined surface can have a main wall surface portion larger than the guide shelf portion.

In this way, the first washing water liquor is taken out to the guide shelf portion, guided to a substantially transverse turning in the vicinity of the flow surface, and more reliably generates a small swirl flow of the turning lead. The second washing water liquor is taken in by the large main wall surface part of the inclination, and the inclination can reliably cause the large flow of the turning lead. As a result, the pushing performance by the swirl flow can be more surely increased, and the dirt can be reliably caused in the swirl flow with a small lead.

In this case, the circumferential wall portion of the second ball circumferential wall portion may be caused by the inflow of the washing water into the flow channel, and the expansion ratio of the flow surface area to the increase in the flow level may be within about 40% of the original width.

In this way, since the 2nd washing water liquor guide | induced by the main wall surface part of the 2nd ball circumferential wall part raises the flow of a large lead more reliably to flowing water, the pushing performance by the above-mentioned turning flow can be improved more reliably.

Further, when the main wall surface of the second ball circumferential wall portion is steeply inclined at an angle of about 5 to 25 ° from the vertical cross-sectional shape of the second ball circumferential shape to the circumferential wall surface of the flowing water surface and the main wall surface portion, the second guide guided from the main wall surface of the main wall surface portion It is preferable to set the washing water liquor as the swirl flow of the large lead.

In addition, in order to solve at least a part of the above problems, the second toilet of the present invention discharges the supplied water from the upper portion of the toilet bowl, and causes the toilet bowl to rotate in the flowing water stored in the toilet bowl to clean the toilet. In

A raceway leading the water supply cleaning water to the upper periphery of the toilet bowl part;

The raceway has two discharge portions for discharging the feed water washing water at a diagonal position with respect to the center of the flowing water in a horizontal plane of the toilet, and each of the discharge portions causes the feed water washing water to flow in the same direction to the flowing water. It is characterized by joining.

Even in this case, the confluence of the flow of the washing water from the discharge portion in each discharge portion occurs almost parallel to the flow water in the toilet horizontal plane, and causes the flow water to rotate in the same rotational direction. Therefore, also in this toilet, there is an advantage similar to that of the first toilet because it can reliably induce swirl flow in the running water as in the first toilet described above.

Moreover, also in this 2nd toilet bowl, the various forms of the same shape as a 1st toilet bowl can be employ | adopted.

In addition, in order to solve at least a part of the above-described problems, the third toilet of the present invention is a toilet in which the water supplied washing water flows into the running water stored in the toilet bowl part and discharged from the siphon trap like the flowing water,

The siphon trap has a trap opening opened on the side of the toilet bowl, and has an upward conduit which forms a conduit upwardly inclined from the trap opening;

A normal pipe portion connected to an upper end of the rising pipe portion and curved, and having a top bank defining the water level;

In the downcomer part connected to the top pipe part and descended, the washing water flowing down the upcoming part and the top part of the downcoming part by the inflow of the water supply washing water into the flow channel. A pipe line part which receives the water and causes splashing of the washing water, a downstream pipe line part which leads the pipe shelf part and the flushing water to the downstream side, and a narrow pipe furnace area at the end of the downstream pipe line part to clean the toilet water. And having said downcomer having a throttle leading to an external drain,

The downcomer is configured to receive the washing water flowing over the top bank from the pipe shelf part when the washing carried from the rising pipe part is discharged to the drain port, and the flowing direction of the washing water flowing down. The flow change to the throttling part side and the storage of the flowing washing water at the throttling part are caused to cause a seal by the rinsing water of the upstream pipe in the throttling part; Even if air remains in the pipe part from the pipe to the pipe shelf part, it is possible to form a water column that reaches the top bank of the washing water stored in the throttle part, and after the water column is formed To siphon the washing water in the toilet bowl part by sealing the air into the Generated by it has a continuously falling possible that the channel-shaped siphon action.

In the third toilet of the present invention having the above-described configuration, when the flushing water starts to flow into the flow channel and the toilet is started, the flushing water flowing from the ascending pipe over the top bank of the top pipe is lowered into the down pipe line. It is taken in wealth and jumps up. The washing water splashed in this way changes the direction of the flow of washing water to the throttle side and flows down the downstream side. At this time, the flow rate of the washing water due to the drying of the air in the downcoming pipe portion and the flow rate of the washing water according to the change of the flow direction It leads to a decrease in the axial section of the downstream side pipe end. The washing water reaching the throttle flows out of the drain through the throttle, causing the air to curl, but is stored in this throttle based on the narrow pipe area. The stored wash water flows out of the outlet part through the throttle. In this case, since the flow rate of the flushing water flowing down the top bank from the lowering of the flow rate decreases during the storage of the flushing water is superior to the flow rate of the flushing water flowing through the throttle to the outlet, the washing starts. Initially, the storage of the washing water at the throttle and the discharge to the drain can be caused in parallel. In addition, since the storage water of the washing water in the throttle increases as the washing water flows down into the downcomer, the downstream water is sealed in the washing water stored in the upstream pipe in the throttling portion. In this way, after the sealing is performed, a subsequent column of washing water flows to reach the top bank from the throttle, and a water column prevents the inflow of air from the outside of the outlet.

As described above, in the cleaning step after the sealing by the washing water and the formation of the water column, since the water is passed by the water head when the formed water column is dropped from the downstream conduit to the outlet, decompression occurs in the trap. . In addition, the inflow of the washing water which flows through the ascending pipe section through the summit bank and flows into the descending pipe section continues even during this decompression phenomenon, so that no air is inhaled from the ascending pipe section. Therefore, the so-called siphon action that sucks the flushing water of the toilet bowl part occurs due to the difference between the flowing water surface of the toilet bowl part and the height of the throttle part, and the siphon action continues until the siphon disappearance by air suction occurs. For this reason, the dirt of the toilet bowl part is forcibly attracted to the siphon trap and discharge | released with the flow water and the feed water washing | cleaning water.

In the situation of the beginning of the washing, which causes the formation of water column of the washing water, as described above, the spring of the washing water is splashed in the pipe shelf of the descending pipe part, and the air is curled and the pipe is lowered by the splashing water. Causes air emissions after wealth. In this case, the air which has not been discharged after the pipeline shelves is stored in the pipeline portion from the top pipeline section up to the pipeline shelf section since the water column has already risen after formation of the water column of the sealant. Alternatively, the rising air is stored and placed in the guide piece having the top bank protruding.

The remaining of air is remarkable when the toilet is washed in a small amount of washing water, and the toilet is washed in a large amount of washing water so as not to occur in the existing toilet where all the air in the trap pipe is discharged. However, in the present invention, as described above, even if air remains in the pipe portion from the top pipe portion to the pipe shelf portion, after devising the shape of the down pipe, after sealing the remaining air, it is possible to form a water column so as to form a siphon. The occurrence of action continued to occur. For this reason, the siphon action can be continued by supplying a relatively small amount of washing water. If the siphon action occurs, the remaining air sealed in the top pipe is drawn into the suction water, but the water column will be formed until it reaches the top bank, so it is difficult to be discharged from the outlet through the water column. do. Therefore, fracture of the water column due to the discharge of the remaining air is less likely to occur, which is preferable for the sustaining of the siphon action.

Thus, there are the following advantages in that the generation of the siphon action can be continued even though air remains in the beginning of the cleaning in some pipeline portions of the siphon trap.

As described above, in a toilet having a siphon trap, it has been important to discharge all the air in the siphon trap conduit outside the trap at the beginning of the washing start with respect to the inflow of the feed water to the flow channel. For this reason, it is necessary to continuously flow a large flow rate of wash water into the toilet bowl part from the beginning.

In the toilet of the present invention, since the air discharge from the siphon trap is not necessary in the beginning of washing, it is sufficient to continuously carry out the inflow of the feed water washing water into the flowing water at an initial flow rate. Therefore, in using the washing water tank for washing water supply, the head pressure of the tank can be lowered, so that only the portion thereof can suppress the washing water tank height. As a result, row silhouette of a toilet bowl can be improved and designability can be improved.

In addition, when directly supplying the washing water of the primary pipe such as a water pipe to the toilet, the inflow of the water supply washing water into the flowing water can be continued from the initial flow rate even if the primary water supply pressure is low. Therefore, the toilet of the present invention can be applied even in a region where the primary water supply pressure is low from the water supply situation, the precipitation situation, or the climatic and regional characteristics, thereby increasing the versatility. In addition, even in a country or region where high water pressure is required due to legal regulations, the toilet of the present invention can be easily applied and installed by providing a pressure reducing valve.

In order to generate the swirl flow in the flowing water and to push the washing water into the trap, it is sufficient to discharge the washing water joining the flowing water at a small flow rate in order to cause the swirl flow. That is, it is not necessary to cause the washing water discharge at the high water washing based on the large flow rate, and it is preferable to discharge the washing water at the relatively low washing water of the small flow rate and join the flowing water. Therefore, when generating the swirl flow based on the confluence of the washing waters into the flow channel, it is possible to prevent the turning confusion that is not necessary for the swirl flow by discharging the washing water at low water washing (oil flow rate). As a result, the energy (washing water) of the discharged washing water can be used without waste in generating the swirl flow, and the stability of the swirl flow can be formed and the efficiency of pushing the wash water into the trap based on the swirl flow can be improved.

In addition, since it is not necessary to cause the washing water discharge at high water washing based on the large flow rate, it is possible to suppress the generation of the sound due to the washing water discharge and the confluence of the washing water into the flowing water, and to improve the staticness at the time of washing the toilet bowl. have. In addition, unprepared water splash can be suppressed by washing water discharge at high water washing.

In order to solve at least a part of the above problems, the fourth toilet of the present invention is a toilet in which the flushing water supplied to the flow water stored in the toilet bowl portion is discharged from the siphon trap with the flow water,

The siphon trap has a trap opening opened on the side of the toilet bowl, and has an upward conduit which forms a conduit upwardly inclined from the trap opening;

A normal pipe portion connected to an upper end of the rising pipe portion and curved, and having a top bank defining the water level;

In the downcomer part connected to the top pipe part and descending, the downflow path part caused by the inflow of the water supply washing water into the flow channel, and the washing flowed down to the downcomer part over the top bank of the top pipe part; Pipe line part which collects water and raises washing water, downstream pipe line part which leads the wash water which protruded from said pipe shelf to the downstream side, and narrows the pipe furnace area at the end of the said downstream pipe part, And the downcomer having a throttle leading to a drain hole outside the toilet bowl,

The downcoming pipe portion is configured to receive the washing water flowing from the upcoming pipe portion to the drainage outlet at the pipe ledge of the washing water flowing down the top bank, and the flowing direction of the washing water flowing down. Air left in the top pipe line because the change of the flow switching to the side of the throttle and the storage of the flowing down washing water at the throttle, and the sealing by the washing water from the throttle to the upstream pipe The ascending portion is pressed by the washing water that has risen to the rising pipe portion and flows into the pipe after the top pipe portion and seals the introduced air downstream from the top pipe portion so as not to return to the top pipe portion side, the throttle portion The washing water stored in the tank forms a water column reaching the summit, and the toilet bowl three By generating a siphon action to suction the number it has a continuously falling possible that the channel-shaped siphon action.

In the fourth toilet of the present invention, when the flushing water is to flow from the ascending pipe portion to the descending pipe portion beyond the top bank of the normal pipe portion, the air is pressed by the air in the normal pipe portion by the washing water. It differs from the said 3rd toilet of this invention in the point which is supposed to flow in a pipeline. That is, even in the case of water supply in the small flow rate, the air in the top duct is depressed and flows into the duct after the top duct due to the relationship between the up duct area and the top duct area.

Part of the air introduced by the washing water is rolled into the washing water reaching the throttling portion, such as the third toilet, and flows out of the throttling portion to the drain port, but the air not discharged rises the pipeline. When such air rises up to the normal pipe part, it causes breakage of water column, that is, loss of siphon action. However, in the present invention, the air is sealed downstream from the top pipe section so as not to return to the top pipe section. Therefore, the same effect as the above-described third invention can also be obtained in the fourth toilet of the present invention.

Also in the 3rd and 4th toilets of this invention which have the said structure, the following various forms can be employ | adopted.

That is, the downcomer part has a downcomer shape that is continuous with the occurrence of the siphon action with respect to the inflow of the feed water washing water into the flow channel at a flow rate of about 50 to 100 liters.

This makes it possible to achieve forced suction of dirt, running water, and washing water due to the siphon effect even at a flow rate smaller than this, as well as at a flow rate substantially based on a conventional flow rate.

In addition, the top conduit portion has a conduit shape so that the conduit portion connected to the downcomer portion is partitioned as an air remaining area on the boundary of the flow of washing water entering the downcoming portion over the top bank. In this case, since the air remaining region can be made into a normal pipe part, air can be efficiently dried out by the flow of the washing water falling into the downcoming pipe part and discharged to the outside, thereby sealing and forming a water column. There is an advantage of the effective inflow and discharge of the siphon generated and the flow of the toilet bowl and dirt.

In addition, the top pipe portion connects the rising pipe portion and the down pipe portion in a cross-sectional area larger than the pipe cross-sectional area of the rising pipe portion.

In this way, since the sealing area of the remaining air can be securely ensured, the air can be more effectively curled and discharged by the flow of the washing water falling into the downcomer, so that the sealing and water column formation, as described above, Thereby, the siphon generation and the flow and dirt of the toilet bowl part are attracted effectively, and there is an advantage in discharge. Although it is preferable to make the top pipe section larger in cross section than the pipe cross section of the ascending pipe section, the normal pipe section is almost the same as the cross section of the rising pipe section due to the flow rate, the area of the throttling section, and the situation when the water flows into the flow channel. The following cross-sectional area may also be used. In this way, the washing water can be efficiently stored in the downcomer.

In addition, the downcomer has a downcomer shape that gradually decreases until the area of the cross section of the conduit from the conduit shelf part to the throttle part becomes an area of at least the same as the cross-sectional area of the conduit of the upcoming part.

In this way, when the area west side is planned, the end face of the downcomer can be formed into a cross-sectional shape that is narrowed toward the conduit axis in the toilet left and right direction.

In this case, the above-mentioned air sealing and sealing can be more reliably generated because the washing water that has jumped from the pipeline shelf of the downcomer over the top bank can seal a portion of the downcoming line at an early time and can be stored in the throttle. It is possible to improve the reliability of generation and continuation of the siphon action by the discharge and the formation of the water column. As a result, by the siphon action, forced suction of dirt and the like can be ensured to increase the dirt discharge performance.

In addition, the cross section of the downcomer of the downcomer is formed in a cross-sectional shape concentrated on the side of the conduit axis in the toilet left and right direction and has the following advantages.

In addition to the cross-sectional shape, the downcomer is provided with the downcomer so that the washing water that has fallen beyond the top bank springs up to the side of the toilet bowl so as to be led to the constrictor, and the constrictor has the guided wash water. The toilet bowl has a shelf portion to be picked up by the toilet bowl side and receives the washing water from the shelf portion, and then guides the washing water to the drain.

For example, a rod-shaped material such as a cotton swab or a match may be used around the toilet bowl, and these rod-shaped articles may accidentally enter the toilet bowl, be mixed with the washing water, and flow into the trap. These rod-shaped objects reach the downcomer part like washing water, jump out to the side of the toilet bowl part like washing water falling over the top bank, and flow down to the throttling part. .

Since the pipe cross section of the downcomer part is concentrated toward the conduit axis side in the left and right direction of the toilet, the rod-like object passing through the down pipe part is prepared to pass by the cross section of the corresponding pipe line. In other words, the rod-like object is a posture in which the rod is substantially aligned with the long direction of the cross section of the pipe (forward and backward direction), or the long direction of the rod with respect to the long direction of the cross section of the pipe (forward and backward direction of the toilet) in the direction of flowing water (dropping direction The pipeline does not flow only in a position where it is allowed to cross. For this reason, the rod-like object which has fallen in such a posture is directed to the shelf of the throttle part so that the flowing direction of the washing water toward the shelter side of the throttle part and the long direction of the rod almost coincide with each other when jumping up to the toilet bowl side. Since the sticking of the rod-like object occurs also in this shelf part, the rod-like thing after the shelf part almost coincides with the long direction of a rod in the direction of the flow of the wash water toward the drainage port which the washing water goes to afterwards. The rod-like material thus entered enters the drain from the long end toward the drain. Therefore, it is possible to effectively avoid a situation in which the rod-shaped object is blocked at the throttle.

In addition, in order to introduce the supplied washing water into the flowing water stored in the toilet bowl part, as described above, the first and second washing water mainstreams are generated to cause the swirling flow in the flowing water, or effective to cause such swirling flow. The toilet bowl having a circumferential wall shape can be provided.

In this way, the above-mentioned effect can be achieved by improving the pushing efficiency by the above-mentioned swirl flow, and in addition to the above-described effects, the occurrence of the siphon effect and the continuation of the siphon effect in the air remaining.

In addition, in order to solve at least a part of the above problems, the fifth toilet of the present invention has a toilet bowl for storing running water, a toilet main body for supporting the toilet bowl, and a siphon action during discharge of dirt. A siphon trap pipe line, and the siphon trap pipe line is inclined from the trap opening opened at the bottom side of the toilet bowl part to the upper side, and is connected to an upper end of the rising pipe section to form a curved pipe line; In the toilet which has the summit which defines the water level, and the toilet which is formed as the descending piping part which descended in connection with the said normal pipe part,

The wall surface in a predetermined range from the connection portion of the ascending pipe portion to the connection portion with the descending pipe portion in the curved wall portion of the curved conduit of the top conduit facing the top bank, in the state before casting the toilet bowl The siphon trap conduit except for the part and the casting of the toilet bowl and the toilet body are separated from each other.

The casting of the wall portion is joined to the casting of the remaining siphon trap conduit to prevent the siphon trap conduit from firing.

In the fifth toilet of the present invention having the above-described configuration, in the curved pipe section of the siphon trap pipe line in the state of casting before firing, a wall portion having a predetermined range of the pipe wall facing the top bank from the connection part of the rising pipe part is formed. It does not exist over the connection part with the downcomer part. Therefore, since there is no location with respect to this wall surface part, the metal mold | die for forming the inner wall of a rising pipe part or a top bank can be set to another metal mold | die. For this reason, the casting of the side closely deposited on the mold surface of the mold can be used as the inner wall surface or the top bank wall surface of the ascending pipe section. Therefore, these parts can be either the inner wall without irregularities or the normal bank to have the protruding portion in the pipeline. have. And the casting of the wall surface part is joined to the casting of the siphon trap pipe | tube, and this pipe | tube is blocked and becomes a continuous siphon trap pipe | tube, and it bakes after that. The mold for forming the summit bank is limited to a set of other molds, but since the degree of freedom is increased with respect to the mold shape, the shape of the siphon trap pipe can be diversified.

In addition, the manufacturing method of the present invention to produce a toilet for solving at least a part of the above problems, the toilet bowl for storing the running water, the toilet body for supporting the toilet bowl, and generates a siphon action during discharge And a siphon trap conduit configured to connect the siphon trap conduit to an upward conduit inclined upwardly from a trap opening opened on the bottom side of the toilet bowl and to an upper end of the elevating conduit to form a curved conduit; In the manufacturing method of the toilet formed of a top pipe section having a top bank to define the water level, and as a descending down pipe section connected to the top pipe section,

In the wall portion of the curved conduit of the top conduit portion, which is a conduit wall facing the top bank, a wall portion casting of the wall portion of the wall portion in a predetermined range from the connection portion of the ascending passage portion to the connection portion with the descending conduit portion is formed by mold molding. Process (1) to do,

A step (2) of forming a toilet casting unit in which the siphon trap pipe and the toilet bowl part and the toilet body are integrally formed except for the wall part; and the wall part casting is joined to the toilet casting to siphon the siphon. Blocking (3) the trap conduit and performing firing in a state in which the siphon trap conduit is formed such that the rising conduit section, the top conduit section, and the descending conduit section are continuous;

The said process (2) has a bottom wall shape of the said toilet bowl part, the bottom wall shape of the said toilet main body, and the outer wall shape of the said downcoming pipe part among the remaining siphon trap pipe | tubes except the base wall surface part, and a suitable main part shape. A bottom mold, a side mold having a concave portion suitable for the side wall shape of the toilet body, a ball center mold having a convex shape suitable for the inner circumferential wall shape of the toilet bowl, and a pipe line of the ascending pipe portion of the siphon trap pipe. The inner wall shape and the outer shape suitable for the top bank shape of the top pipe portion, and is a separation mold that can be embedded in the ball center mold, and when embedded in the ball center mold, the bottom of the toilet bowl portion of the convex shape of the ball center mold A ball for joining to a portion suitable for an inner wall to prepare the separation mold whose joining point is an opening point of the trap opening. And forming the toilet casting in which the siphon trap conduits and the toilet bowl part and the toilet body are integrated with each other except the wall portion in the recessed and concave shapes of each mold. And a step of forming the cavity, and a step of acquiring the toilet casting through slip flow into the cavity, slip deposition into the molds, varnish, drying, and mold molding. do.

According to the toilet manufacturing method of this invention which has the said structure, in the curved conduit of a top pipe part, the wall surface part used as the pipe wall surface facing a top bank shall be separate from other toilet parts in the state of the casting. Therefore, there is no point in this wall part in the toilet casting formation, so that the separation mold can be embedded in the ball center mold to form the inner wall or the top bank of the rising pipe part, and the side close to the mold surface of this separation mold is deposited. The casting surface of can be the inner wall surface of the ascending pipe section or the top bank wall surface. For this reason, as mentioned above, since the degree of freedom becomes high regarding the mold shape of this separation mold, the toilet which diversified the siphon trap pipe shape can be manufactured easily. In this case, since the joining position between the separation mold and the ball center mold is used as the opening of the trap opening, the trap opening can be formed with high dimensional accuracy.

The toilet and the manufacturing method of this invention which have the said structure can employ | adopt the following various forms.

That is, the end pipe part located at the end of the siphon trap pipe and connected to the drain port outside the toilet is separated from the toilet in its casting state, and the casting of the end pipe part is joined to the end of the siphon trap pipe in the casting state and fired. I shall do it. The terminal pipe part is cast from a plurality of prepared shapes so as to cope with a case where the distance between the drainage port and the rear end of the toilet is different at the time of casting formation. The joining position is adjusted according to the above distance. In this case, it is preferable to prepare a mold necessary for the production of the end pipe part while the mold of the toilet main body having the siphon trap pipe is common, so that the mold production and its management cost can be reduced. Furthermore, the toilet obtained through the joining of the end pipe casting, and then firing, can be adapted to the porcelain toilet itself to be suitable for the above distance, which is one of the drainage means, that is, rough in from the toilet wall to the drainage center.

In this case, it is possible to press the annular sealing member disposed around the drainage port with the end pipe portion facing the drainage port, to seal around the drainage port, and to drain the drainage port. This makes it possible to avoid the leakage of the drainage in the end pipe part itself during drainage to the drainage port, and in this case, it is convenient because it does not require a bent socket or the like.

Further, the end pipe portion is opposed to the drain port and interposed between the drain hole and the end pipe portion. It may be connected to the drain through the drain connector (connector). In this way, leakage of the drainage during drainage to the drain can be avoided via the drainage connector. And since this drain socket should just connect the end pipe part and a drain hole which have opposing relationship, it is sufficient to make it straight and it is easy to handle since it is simple in shape.

In addition, the end pipe portion can be inserted into the drain port, so that the entire toilet including the end pipe portion is made of porcelain, and the toilet can be installed by inserting the end pipe portion into the drain. Therefore, the installation of sockets and the like and the process and facility management for the manufacture of sockets become unnecessary, which is advantageous in terms of cost. In addition, since the end pipe portion can be inserted into the drain port, the siphon trap pipe having the end pipe part can be suited to the drain port means while being porcelain.

As described above, since the end pipe part can be formed alone, the casting is formed into an iron mold and a yaw mold, and the outer diameter shape is defined in a toll mold, and the inner diameter shape is formed from an iron mold. It becomes possible to define. Therefore, the end pipe portion can be formed such that the inner and outer wall shapes have different shapes, for example, the outer wall is cylindrical and the inner wall is elliptical.

In addition, the fifth toilet of the present invention, in the toilet having a toilet bowl for storing the running water, a toilet body for supporting the toilet bowl, and a siphon trap pipe for generating a siphon action when the waste discharge, Located in the end of the siphon trap conduit, the end conduit connected to the drain port outside the toilet, having the end conduit for connecting the down conduit to the drain via the end conduit, the end conduit before firing the toilet In the casting state, the siphon trap pipe, the toilet bowl and the toilet body and the casting is separate, and the casting of the end pipe portion is characterized in that the firing by joining the end of the siphon trap pipe in the casting state.

In this case, even in a toilet which does not require a feature on the inner wall or the top bank of the ascending pipe section, the terminal pipe section is separately prepared in the casting state, and thus the same effect as the drainage fitting in the ceramic toilet bowl itself can be achieved.

Hereinafter, the form of the toilet which concerns on this invention is demonstrated based on an Example.

1 is an explanatory view for explaining the toilet 10 of the embodiment by cutting its upper surface, FIG. 2 is an explanatory view showing the toilet 10 in FIG. Fig. 4 is an explanatory view showing a cross-sectional view in the same right direction, and Fig. 4 is an explanatory view showing a part of the central portion of the rim shown in Fig. 2 after being cut away. The toilet 10 of this first embodiment is characterized by the pipe shape of each part of the siphon trap pipe as described later, so that the siphon action can be generated and continued even by the supply of washing water at a low flow rate. . First, the whole toilet will be described.

As shown in these figures, the toilet 10 is equipped with the toilet bowl part 12, and makes the rim 14 the upper periphery. The rim 14 is formed to surround the toilet bowl portion 12 and has a hollow rim raceway 16 therein. The rim raceway 16 is connected to the wash water feed passage 18 at the rear of the toilet.

The rear side of the toilet bowl part 12 is a device storing part 11 for storing the washing water supply device described later, and the washing water supply passage 18 is connected from the washing water supply device stored in the device storage part 11. The ball 19 receives the water supply of the washing water. The washing water supplied to the washing water feed passage 18 enters from the left and right directions of the rim raceway 16 and is led to the upper periphery of the toilet bowl 12 as shown in FIG.

The toilet bowl 12 is connected to the siphon trap 20 at its bottom 13. The siphon trap 20 includes a trap inlet 22 which is open toward the ball bottom 13, a rising conduit 24 which forms a conduit upward from the trap inlet 22 to the rear of the toilet bowl and upwards; It is connected to the upper end of the upward conduit section 24 has a top conduit section 26 curved downward, and a descending conduit section 28 is connected to the top conduit section 26 to descend. The summit passage section 26 has a riser section 24 and a connection section having a summit bank 30 that is bent toward the descending route section 28. (RS) specifies the level of water. The pipe form of this siphon trap 20 is mentioned later.

The rim 14 has a base portion first water discharge hole 41, a base portion second water discharge hole 42, and a left central water discharge hole 43 on the left side of the toilet shown in FIG. In addition, a first calibration water jetting hole 45 is formed between the central left water jetting hole 43 and the rim shear side water jetting hole 44, and the left central water jetting hole 43 and the base are provided. A secondary auxiliary water jetting hole 46 is provided between the secondary second water jetting holes 42. In addition, the rim 14 has a right central bubbling hole 47 on the right side of the toilet, and a porous second calibration soil between the right central bubbling hole 47 and the rim front side water jetting hole 44. The fourth water jetting hole 50 and the auxiliary water jetting hole between the water hole 48 and the third proofing water hole 49 between the right central water discharge hole 47 and the connection part of the washing water supply passage 18 Has 51.

The base first water jetting hole 41 and the base second water jetting hole 42 are formed on the bottom side of the rim raceway 16, and as shown, a length-long hole shape (width × length in this embodiment is 12 x 43 mm in the base part 1 of the water jetting holes 41 and 13 x 35 mm in the base part of the second water jetting holes 42). Auxiliary Sewage Work (46), First Calibration Sewage Work (45), Rim Shear Sewage Work (44), Second Calibration Work Sewage Work (48), Third Calibration Work Sewage Work (49), Right Central Sewage Work (47) , The fourth calibration jetting hole 50 and the auxiliary jetting hole 51 are formed on the bottom side of the rim raceway 16 in a substantially circular hole shape. In this case, the hole diameter of the water jetting hole is about 4 mm in the auxiliary jetting hole 46 and the auxiliary jetting hole 51, about 13 mm in the first calibration jetting hole 45, and the rim shear side jetting hole ( 44) and the second calibration soil (48) is about 10 mm, the third calibration soil (49) and the fourth calibration soil (50) is about 5 mm, and the right central soil (47) is about 16 mm It is.

The washing water flowing into the rim raceway 16 passes through the rim raceway 16 along the raceway path at a speed (flow rate) depending on the flow rate applied to the rinse water supply system, and at the point of reaching each water hole, the rim raceway It has a directionality depending on the position of the surrounding water jetting hole.

Therefore, each of the above water jetting holes discharges the washing water to the side of the bowl bottom portion 13 along the surface of the toilet bowl part 12 while reflecting the directionality of the washing water as shown schematically in FIG. 1.

The left ridge portion 52 and the right ridge portion 53 which are raised from the bottom of the raceway are formed at substantially center portions on the left and right sides of the toilet in the rim raceway 16. This left ridge portion divides the rim raceway 16 into an enlarged raceway 16a with a wide cross section of the raceway and a narrow raceway 16b with a narrow cross section of the raceway. Therefore, the water flow rate of water is increased in the expansion raceway 16a, and the washing water rectified by the left and right ridges flows in the narrow raceway 16b.

The base portion of the first water discharge hole 41 and the base portion of the second water discharge hole 42 at the time of discharging the washing water from the water discharge holes such as the base portion 1 water discharge hole 41 and the like, In addition, when the water jetting hole from the expansion channel 16a is close to the washing water feed passage 18, the washing water is discharged at a larger flow rate than the other water jetting holes. In addition, the first orthodontic water jet hole 45, the right central bubbling hole hole 47, the rim shear side water jet hole 44, and the second orthodontic jet hole 48 are formed by the rectification in the narrow raceway 16b. The washing water is discharged in a stable direction, and the discharge amount at that time depends on the hole diameter.

As shown in FIG. 4, the left central bubbling hole 43 is formed in the left ridge 52 with a hole diameter of about 16 mm, and the opening direction thereof coincides with the washing water passing direction of the expansion channel 16a. Therefore, the washing water discharged from the left central bubbling hole 43 is advanced straight from the left central bubbling hole 43 and is guided to the upper circumferential circumferential wall 55 of the toilet bowl 12 at the bottom of the rim 14 and its discharge trajectory. Is as shown in the discharge trajectory TS in FIGS. 2 and 3. In this case, the rim 14 has a dripping plate part 56 from the left bulge part 52 to the toilet bowl part 12 side of the narrow channel 16b from the left bulge part 52 to the toilet front side, and the front region of the left central bubbling hole 43. This is enclosed by the lower plate portion 56 and the bottom portion 57 and the upper circumferential wall 55 of the narrow channel 16b. Therefore, the left central bubbling hole 43 has high directionality and convergence and discharges the washing water to the discharge trajectory TS.

Next, the operation of the washing water in the case where the washing water is discharged from the base portion first water jetting hole 41 or the like will be described.

FIG. 5 is an explanatory view for explaining the operation of the washing water discharged from the base first jetting hole 41 and the base second jetting hole 42, and FIG. 6 is the left central bubbling hole 43 and the first proofing soil. It is explanatory drawing explaining discharge of the washing water from the water | work 45, the rim shear side water discharge 44, the 2nd correction water discharge 48, and the right central water discharge 47, and FIG. Fig. 6 (b) is an explanatory diagram for explaining the operation of the washing water caused by the discharge of the washing water from each water jetting hole, when it is assumed that the washing water is discharged alone. . FIG. 7 is an explanatory diagram schematically illustrating the operation of the washing water caused by the discharge of the washing water from all the water discharge holes. FIG. 8 shows that each of the liquors causing the washing water operation is individually joined to the running water RS. Fig. 9 is an explanatory diagram schematically illustrating the operation of turning at flowing water when both mainstreams simultaneously join the flowing water RS.

As shown in Figs. 1 and 5, the base portion first water discharge hole 41 and the base portion second water discharge hole 42 are formed at the rear side of the toilet bowl and open to the bottom of the expansion raceway 16a. Therefore, both jetting water inclines the washing water toward the toilet bowl front side and is inclined with respect to the flowing water RS to discharge therefrom. In this case, since both jetting holes have a long hole shape, the discharged water is discharged to be wider and wider than the long hole shape. Since both of the water jetting holes are formed adjacent to each other, the flows of the washing water after discharge are merged to form a mainstream (first mainstream S1) of a flow having a precise directivity and strong water washing by this confluence, and the first mainstream (S1). ) Is joined to the running water (RS). This first liquor S1 merges from the water discharge hole position and the washing water discharge direction in a plan view, inclined from the left side of the toilet bowl, toward the right front side. In addition, the first main stream S1 joins the running water RS by adopting a stable trajectory from the confluence of the washing water streams from both water jetting holes. The flushing water which does not participate in the formation of the first liquor S1 discharged from the water jetting holes flows to both sides of the first liquor S1 to join the flowing water RS, and the toilet bowl part in which the first liquor S1 does not reach 12) Wash the surface. The same applies to the discharge washing water from the auxiliary jetting hole 46.

The left central bubbling hole 43 discharges the washing water guided to the rim raceway 16 from the same side as the base first water jetting hole 41 and the base second water jetting hole 42 (in detail, the toilet left side). do. The washing water discharged in this way flows in the discharge trajectory TS described as it circulates along the upper peripheral wall 55 (see FIG. 4) as shown in FIG. 6 (a). However, together with the discharge of the washing water from the left central bubbling hole 43, the first orthogonal jetting hole 45, the rim shear side jetting hole 44, the second calibration jetting hole 48, and the right central jetting hole 47 are Discharge of the washing water also occurs. The washing water discharge from each of the water discharge holes intersects the discharge trajectory TS of the discharge washing water discharged from the left-center central water discharge hole 43, respectively. Therefore, in the flow of the cleaning water of the discharge trajectory TS, the discharge cleaning water from the first calibration water discharge hole 45, the discharge cleaning water from the rim front side discharge hole 44, and the second correction water discharge hole 48 at the front side of the toilet. ) And the discharge cleaning water from the third calibration jetting hole 49 are sequentially joined. Further, on the right side of the toilet which is the reaction side of the left central bubbling hole 43, the discharge water from the right central bubbling hole 47 is discharged from the right central bubbling hole 47 by the washing water flow of the discharge trajectory TS. The wash water joins.

The confluence of the washing water corrects the flow of the washing water of the discharge trajectory TS through consolidation, and the flow of the flow having the correct directionality and strong water washing by merging the flow of the washing water of the discharge trajectory TS. Two main streams S2), and the second main stream S2 is joined to the flowing water RS. This second liquor S2 is a confluence of the washing water flow in the discharge trace TS around the upper periphery circumference wall 55 from the front side of the toilet and the left side of the toilet. As shown in the figure, inclined from the right side of the toilet bowl and joined toward the left rear side. In the second liquor S2, since the discharge cleaning water from a plurality of water jetting holes such as the first calibration jetting hole 45 has been merged and corrected, a stable trajectory is adopted to join the flowing water RS and flow out. At the time of confluence, as shown in Fig. 6 (b) or Fig. 7, a substantially parallel relationship is employed between the first liquor S1 and the toilet in the horizontal direction of the toilet, and the flow of water by confluence of both liquors ( Swirl flow in the same rotational direction occurs in RS). In addition, in the auxiliary jetting hole 51 or the fourth straightening jetting hole 50 on the side of the jetting hole, the second mainstream S2 does not reach and washes the surface of the toilet bowl part 12 (rear toilet side surface).

In this way, the first liquor S1 and the second liquor S2 are substantially parallel to the flowing water RS in the horizontal direction of the toilet, and have a relationship such that the rotating flow in the same rotational direction is generated in the flowing water RS. In the toilet 10 of the embodiment, when each liquor causes a swirl flow in the flowing water RS, the liquor of each other does not merge with the confusion in the turning direction of the swirl flow. For this reason, since the turning is promoted without disturbing the turning flow, the energy (washing water) of the discharged washing water can be used without waste for generating the turning flow, thereby increasing the efficiency of pushing the flowing water by the turning flow. In addition, such an effect is mentioned later.

Hereinafter, the ball part inner wall structure for causing the confluence of the mainstream will be described.

FIG. 10 is an explanatory view showing the toilet 10 in cross section taken along line 10-10 of FIG. 1 which is near the flowing water confluence of the 2nd mainstream S2. As shown in Fig. 10 or Figs. 1 to 3, in the toilet 10 of the present embodiment, the toilet front side inner wall of the toilet bowl 12 has an upper periphery circumferential wall 55 below the rim 14 and an inclination that follows. The gentle inclined portion 60, the inclined portion 61 inclined greatly, and the lower shelf portion 62 with reduced inclination were placed, and the lower shelf portion 62 was positioned near the water surface in the flowing water RS. The lower shelf part 62 receives the first liquor S1 to guide the turning and shows the turning state of the washing water caused by the first liquor S1 joining the flowing water RS. As described above, the turning lead S1L in the flow direction RS depth direction is made small.

In addition, the toilet rear side inner wall of the toilet bowl part 12 is the rear inclination part 63 which inclined at a substantially large inclination from below the rim 14. The rear inclined portion 63 reaches the trap inlet 22 of the ball bottom portion 13 below the water flow RS surface. In addition, the toilet lateral side inner wall of the toilet bowl 12 has a slanted right and left inclined portions 64R and 64L that are continuous to the upper circumferential wall 55 below the rim 14 as shown in FIG. Inclined portions 65R and 65L. The inclined portions 64R and 64L are second liquors S2 described in connection with the inclined portion 60 on the front side of the toilet and are flushed with washing water at the time of correcting the flaw, and the rear inclined portion 63 on the rear side of the toilet. Is connected to. The inclined portion 64L guides the first liquor S1 to near the running water RS, but since the first liquor S1 flows forward from the rear of the slant, the flow of merging of the first liquor S1 and subsequent turning is given. The guidance can thus be at the lower shelf 62 as described.

The inclined portions 65R and 65L are connected to the inclined portion 61 at the toilet front side and the rear inclined portion 63 at the toilet rear side. The inclined portion 65R and the rear inclined portion 63 subsequent thereto receive the guided second liquor S2 corrected as described above, and guide the joining to the running water RS, and the second liquor S2 after joining is It defines the turning situation of the washing water that occurs when joining the running water (RS). In this case, the inclined portion 65R and the rear inclined portion 63 are inclined greatly together, and the inclined shape of the inclined portion 65R is caused by the rising of the water level (ΔH) and the surface area in FIG. 10 caused by the inflow of the washing water into the flowing water RS. In comparison with the expansion (ΔS), the water surface expansion (ΔS) is about 1/5 to 2/5 with respect to the water level rise (ΔH), and the expansion ratio of the flow surface area to the water level rise is original. It is within about 40% of the area. That is, the second liquor S2 joins the flowing water RS having such a large inclination and is guided by turning at these inclined portions even after the flowing water merges. Accordingly, in the turning situation of the washing water caused by the joining of the second liquor S2 to the running water RS, as shown in FIG. 8, the turning lead S2L in the depth direction of the running water RS becomes large. In addition, since the inclined portion 65R, the rear inclined portion 63, and the inclined portion 65L are curved surfaces, the degree of inclination is explained in comparison with the above-mentioned water level rise (ΔH). The angle formed between the running water level and the circumferential wall surface of the circumferential wall portion can be set at a sharp angle so as to be about 5 to 25 °. In this way, the 2nd mainstream S2 guided by each said inclination part can be made into the turning flow of large lead S2L.

However, the swirl flow which occurs after the joining of the above mainstreams does not occur independently but occurs simultaneously in the flowing water. Therefore, it is inferred by adopting the following operation.

In this way, the swirl flow caused by the second mainstream S2 to the flowing water RS so that the turning lead becomes large is such that the pushing of the flowing water RS based on the turning is directed toward the ball bottom 13 side, that is, the trap inlet 22. do. Furthermore, as shown in FIG. 9, the turning lead caused by the first liquor S1 extends even to a small turning flow, so that dirt and turning washing water that rides on the turning flow of the first liquor S1 are rotated. Push it toward the trap inlet (22). For this reason, the performance of pushing water (RS) or dirt can be made higher. In addition, even when such pushing is exerted, the turning direction of swirl flow does not arise.

In addition, since the toilet bowl part 12 has the ball bottom part 13, the turning radius of the said turning flows toward the trap inlet 22 gradually becomes small, and the momentum of turning flow increases. For this reason, the pushing performance by the swirl flow is also improved. In addition, the effect obtained by doing this is mentioned later.

When the flow of water flow based on the first liquor S1 and the second liquor S2 occurs, the washing water and the dirt in the toilet bowl 12 are introduced into the siphon trap 20 from the trap inlet 22. It is discharged from the siphon trap 20 as follows. Here, the detailed structure of the siphon trap 20 is demonstrated before description of a waste discharge pattern. FIG. 11 is an explanatory view showing the pipe structure along the line 11-11 of FIG. 3 to explain the pipe structure of the siphon trap 20, and FIG. 12 shows the downcoming pipe part 28 in FIG. 3 and FIG. Explanatory drawing which sectional drawing along the -12 line, FIG. 13 is explanatory drawing which sectional view along the line 13-13 of FIG. 3 and FIG. 11, FIG. 14 shows the downcoming pipe part 28, and FIG. It is explanatory drawing in cross section along the 14-14 line of FIG. 3 and FIG.

The top pipe portion 26 extends in the rear of the toilet in succession to the up pipe portion 24 so that the washing water flows from the top bank 30 to the down pipe portion 28. In this embodiment, the top pipe section 26 has a wider cross sectional area than the upward pipe section 24, and as described later, the air seal can be sealed to the uppermost part 70 of the inner wall of the top pipe section 26. It is.

The top duct 26 has a tongue 71 which protrudes downward from the top ridge 30 toward the downward duct 28 in addition to the top bank 30. The summit bank 30 serves as a return point of the pipeline from the ascending pipe section 24 to the downcoming pipe section 28 to correspond to defining the water level as described above, and the tongue 71 is inclined inside the pipeline and protrudes downward. The shape of the shape is said to be guided when the washing water flows down the top bank 30 to the downcomer 28. Therefore, since the washing water reaching the summit bank 30 flows down to the descending pipe part 28 by being guided by the tongue 71, the upper pipe shelf 75 or the lower pipe part described below which the down pipe part 28 has. It reaches the shelf part 77 firmly, it takes out in these shelf parts, and it rises and flows downstream. Since the tongue portion 71 is inclined downwardly and protrudes as shown in the figure, air is clogged at the time of discharging washing water.

The downcomer 28 has a curved conduit 72, an intermediate conduit 73, and a distal conduit 74 from the side of the top conduit 26. As shown in Figs. 11 to 14, the descending pipe section 28 has the curved pipe section 72 and the intermediate pipe section 73 over the terminal pipe section 74 so that the area of the cross section of the pipe line decreases and gradually changes. Equipped. That is, the curved pipe part 72 and the intermediate pipe part 73 are gradually changed in cross-sectional area according to the passing direction of the washing water passing through these pipe parts, and the gradually changing shapes are shown in FIGS. 12 and 13. As shown in the figure, it is concentrated on the pipe shaft center side in the toilet left and right direction.

The curved conduit 72 has an upper conduit shelf 75 at a connection portion of the intermediate conduit 73. The upper pipe shelf 75 is guided to the tongue 71 to pick up the washing water flowing down from the top bank 30, causing the washing water to spring up, and dropping the washing water into the downstream intermediate pipe portion 73.

The intermediate pipeline 73 has a lower pipeline shelf 77 at the connection of the terminal pipeline 74. The lower pipe shelf 77 flows down from the tongue 71 and receives washing water separated from the upper pipe shelf 75 by passing the outer peripheral wall 76 of the intermediate pipe 73 from the upper pipe shelf 75. The water springs up, and the washing water is dropped into the downstream end pipe portion 74.

As shown in Fig. 14, the end pipe portion 74 has a cylindrical outer wall shape, and the inside thereof is a pipe portion 79 having an elliptical cross section. And this end pipe part 74 is so-called slipping to the drain port which is not shown through the drain connector which is not shown in figure, and connects this down-pipe part 28 and this drain port. The terminal pipe part 74 has a through hole 78 opened at the lower end of the pipe part 79 with the lower end shelf part 80 open, and the through hole 78 functions as the opening area is narrowed. The lowermost shelf portion 80 receives the washing water that has splashed on the side of the toilet bowl part 12 by the upper pipeline shelf 75 and the lower pipeline shelf 77 and causes the washing water to spring up. It leads from the through-hole 78 to a drain.

As described above, since the downcomer 28 has an upper pipe shelf 75 and a lower pipe shelf 77, the flow rate of the washing water flowing over the top bank 30 and down the downcomer 28 is reduced. When this amount is small, if the flow rate of the washing water in the lower pipe shelf 77 and springing up and flowing down are large, the washing water is received from both the upper pipe shelf 75 and the lower pipe shelf 77. Provokes the smell and bouncing. Therefore, irrespective of whether the flow rate of the flushing water flows down is large or small, the lowermost shelf 80 of the end pipe portion 74 causes the flushing water to rise and spring up, and then the washing water is discharged to the drain. In this case, the positional relationship between the outer circumferential wall portion 76 of the intermediate pipe portion 73 and the tongue portion 71 of the top bank 30 is the minimum flow rate that the water supply flow rate (discharge amount) from the washing water supply device assumes in this embodiment. Even if it is (about 40 liters), the washing water flowing down from the top bank 30 will surely spring from the lower pipe shelf 77. In addition, the pipe furnace area of the intermediate pipe portion 73 and the opening area of the pipe tube 78 in the terminal pipe portion 74 may be used as the water supply flow rate from the washing water supply device as described later even at the minimum flow rate described above. Storage is supposed to take place.

The waste discharge pattern by the downcomer 28 having such a configuration will be described as the operation of the washing water in the downcomer 28. FIG. 15 is an explanatory diagram for explaining the operation of the washing water at the beginning of washing start, FIG. 16 is an explanatory diagram for explaining how the washing water is stored in the end pipe portion 74, and FIG. 17 is the occurrence of the siphon action. It is explanatory drawing explaining a situation.

When the washing button or the cleaning lever (not shown) is operated to clean the toilet, the washing water flows from the washing water supply device to the rim raceway 16, and as described above, the first liquor S1 and the second liquor S2. ) Flows into the running water (RS). Then, as shown in FIG. 15, since the washing | cleaning water which entered the rising conduit part 24 pushes in the washing | cleaning water which flowed into the flowing water RS, the water level in the raising conduit part 24 rises. The pushing of such washing water is caused by the swirl flow based on the confluence of the first main stream S1 and the second main stream S2 into the flowing water RS in substantially parallel and in the same rotational direction.

The washing water pushed in this way flows down from the ascending pipe part 24 to the downcoming pipe part 28 beyond the top bank 30 of the top pipe part 26. As shown in FIG. 16, this washing water is taken out from the upper pipe shelf 75 or the lower pipe shelf 77 of the downcomer 28 and springs up. The washing water splashed in this way changes the direction of the flow of the washing water toward the downstream end pipe portion 74 and flows down to the downstream side, at which time the flow of the pipe flow along the swept of the air in the falling pipe portion and the flowing direction The lowering of the flow rate of the washing water due to the conversion of the water leads to the downstream end pipe portion 74. By this washing water operation, the sealing is started by the washing water to the downstream pipe line downstream of the upper pipe shelf 75 as follows.

Since the terminal pipe part 74 is provided with the lowermost shelf part 80, the washing | cleaning water also jumps out from this lowermost shelf part 80, and discharges the washing | cleaning water from the through-hole 78. FIG. In this case, since the through-hole 78 has a narrow opening area as shown in FIG. 14, the terminal pipe portion 74 discharges a part of the washing water from the through-hole 78, but the washing water is discharged from the pipe portion 79. Save it).

In the present embodiment, even in a situation where the water supply of the washing water is generated at the minimum flow rate described above, the dropping speed of the washing water is lowered based on the springs from the above-mentioned shelves during storage of the washing water. The flow rate of the washing water flowing down the portion 28 is superior to the washing water flow rate flowing through the end pipe portion 74 to the discharge port. Therefore, in the initial stage of washing start, the storage of the washing water in the end pipe portion 74 and the discharge to the drain can be caused in parallel. And the storage amount of the washing | cleaning water in the terminal pipe part 74 increases with the flow of the washing | cleaning water to the downcoming pipe part 28 continuously. As shown in FIG. 16, the flow of the washing water flowing over the top bank 30, which flows into the down bank 30, which continuously flows down from the tip of the tongue 71 of the top bank 30, is shown in FIG. 16. Activities such as a water curtain over the portion 75 or lower pipe shelf 77.

In the situation at the beginning of the washing in which the washing water is stored and discharged in the terminal pipe part 74, the air remaining downstream from the upper pipe shelf 75 is rolled up by the above-mentioned washing water of the shelf part. It is discharged from the end pipe portion 74. And since the washing water storage in the end pipe part 74 described above is continued, the intermediate pipe part 73 and the end pipe part 74 are filled with the washing water and sealed as shown in FIG. As a result, a column of water reaching the top bank 30 from the end pipe portion 74 is formed by continuing the flow of the washing water thereafter, and at the same time, the air outside the through hole 78 is formed by the washing water column. Entry is prevented. Even after the formation of the water column, the flow of the washing water from the top bank 30 to the downcoming pipe portion 28 continues to flow, and the amount of the washing water stored in the terminal pipe portion 74 increases so that the downstream pipe passage 28 is increased. In the trap, a decompression phenomenon occurs because the washing water bottle is caused by the water head when the formed water column in the c) falls into the through hole 78. In addition, the inflow of the washing water intended to flow through the ascending pipe portion 24 and beyond the top bank 30 to the descending pipe portion 28 continues between these decompressions, so It also does not cause inhalation of air from the air. Therefore, the so-called siphon action that sucks the washing water of the toilet bowl part 12 due to the difference between the flow of the water surface of the toilet bowl part 12 and the height of the terminal pipe part 74 occurs, and the siphon disappearance by air intake occurs. Until this siphoning continues. For this reason, the dirt of the toilet bowl part 12 is forcibly attracted to the siphon trap 20 and discharge | released with the flowing water and the water supply wash water.

By the way, the air remaining in the uppermost part 70 of the inner wall of the top duct 26 is sealed in this inner wall top part 70, and the downcoming part 28 is swept away by the above-mentioned washing water. Air that has not been discharged from) is already formed in the downcomer 28, and since the formation of the water column is completed, the water column is raised to seal the top wall 70 of the inner wall. In addition, air accumulation may occur in the lower surface of the tongue 71. However, in the end pipe portion 74, since the storage and discharge of the washing water occurs and is sealed, air intrusion from the through hole 78 does not occur. In addition, since there is no air suction on the toilet bowl 12 side, the formed water column is not cut by the sealed air and the intrusion air, so that the siphon action generated as described above is continued. For this reason, the dirt of the toilet bowl part 12 is forcibly attracted to the siphon trap 20 with the flowing water RS, and is discharged | emitted by the siphon action. In other words, the toilet 10 is different from the existing toilet that discharges air at a time by a large flow rate of washing water supply, so that all the pipes are fully made, that is, in the inner wall uppermost part 70 of the top pipe part 26. Even in a situation where air remains in the air and the air pools on the lower surface of the tongue 71 are caused, the siphon action is generated and continued by water supply of the washing water at a small flow rate. In order to facilitate the occurrence and continuation of the siphon action, the rising line portion 24, the top line portion 26, the down line portion 28 and the end line portion 74 of the siphon trap 20 are described. Adopted an unusual shape.

In this way, if the siphon action continues to occur, the remaining air sealed to the uppermost part 70 of the inner wall of the top pipe portion 26 is entrained in the sucked washing water and is expected to continue to be discharged along with the washing water.

By the way, in the present Example, as shown in FIGS. 11-14, the descending pipe part 28 was made so that the pipe furnace area narrows toward the downward side. Therefore, since the storage in the terminal pipe portion 74 of the washing water dropped to the downcomer portion 28 beyond the top bank 30 is promoted, the storage situation of the washing water can be more surely generated. For this reason, the above-mentioned air discharge | emission, generation | occurrence | production of the siphon action by sealing, and reliability of continuation can be improved. In the end, the siphon action ensures forced suction of dirt and the like, thereby improving the dirt discharge performance.

In this embodiment, since the turning lead is turning in the first mainstream S1 and the second mainstream S2 which are different from each other, the pushing efficiency due to the turning is increased as judged by the effect comparison described later. Therefore, as described above, the occurrence and continuation of the siphon action under the air remaining situation can be achieved by connecting the U-shaped tube to a suitable location of the siphon trap 20, for example, in the vicinity of the inner wall uppermost part 70 and starting the toilet bowl cleaning. This can be seen by observing the liquid level of the U-time tube from. Fig. 18 is an explanatory diagram showing the installation state of the U-tube in order to confirm the appearance of the occurrence and continuation of the siphon action under the air remaining situation, and Fig. 19 is a graph showing the liquid level of the U-tube.

As shown in the figure, the liquid level of the U-shaped tube 90 shifted toward the positive pressure side at the beginning of the siphon generation, and then became a negative pressure. This can be thought of as follows. That is, in this embodiment, since a part of the downcomer part is sealed by a small amount of washing water at the beginning of washing, when the washing water is pushed into the siphon trap by pushing by turning at the beginning of washing, the remaining air is compressed and the It can be explained that the internal pressure is increased. The negative pressure observed after the generation of the positive pressure can be explained by the fact that forced suction of the washing water in the conduit occurred due to the siphon generation. Therefore, if such a U-tube is a toilet causing liquid level, it is considered that the strong pushing force in the air remaining situation causes the occurrence of water washing and subsequent siphon action and continuation.

In addition, when the flow rate of the washing water used to clean the toilet is set to a total flow rate (approximately 6 liters) as a high efficiency water saving toilet, the above-described changes in the positive pressure and the negative pressure are not started in the existing toilet, which merely causes water flow. Negative pressure only occurred consistently from the beginning.

The dirt discharge effect in the present embodiment will now be described. First, the washing water supply device will be described. The present invention is not subject to structural constraints with respect to the water supply of the washing water, and in the following description, a water supply apparatus using a jet pump (jet pump) will be described. Of course, this can also be applied. FIG. 20 is a perspective view partially illustrating the built-in state of the washing water supply device 100 in the toilet 10, and FIG. 21 is an explanatory view for explaining the periphery of the washing water supply device 100 in cross section.

The washing water supply device 100 is housed in the appliance storage unit 11 behind the toilet to supply the washing water to the rim raceway 16 of the rim 14. This washing water supply device 100 has a washing water tank 108 that stores washing water, as shown in detail in FIG. 21. In addition, the washing water supply device 100 includes a pipe 110 connected to the water supply pipe via the water valve 109, and the branch pipes 110Oa and 110Ob of which the pipe is branched into a bifurcated shape pass through the tank side wall. The water is drawn into the washing water tank 108. Moreover, the upper end of the washing water tank 108 is open, and the internalization and maintenance of the ball tap 115, the jet pump 113, and the like in the tank are simplified.

The branch pipe 110a is provided with a flush valve 111 in the pipeline in the tank and serves as a washing water (operating water) water supply pipe to the jet pump 113. The flush valve 111 has a handle 11la which is operated at the time of flushing the toilet, and passes the washing water downstream through the pipeline by operating the handle.

Downstream of the flush valve 111, a pipe 112 and a pipe 114 are piped through the jet pump 113 as a subsequent washing water pipe. The pipe 112 descends to the vicinity of the bottom of the washing water tank 108, is piped by adopting a path bent laterally along the tank bottom at the lower end, and is connected to the jet pump 113 at the end of the path. A pipe 114 downstream of the jet pump 113 leads the jet pump jet cleaning water past the cleaning water feed channel 18 to the rim raceway 16.

The pipe 114 is piped by adopting a path as shown in Fig. 20, and is upwardly raised from the jet pump 113 to the vicinity of the tank top, and is raised to the side to be washed from the tank side wall. A horizontal pipe portion 114b extending out of the water tank 108, a downcoming pipe portion 114c which is bent and lowered along the tank outer wall, and a communication pipe portion 114d communicating with the washing water supply passage 18 at a downstream end thereof. Has In this case, the horizontal pipeline 114b is piped so that the washing water tank 108 adopts a position higher than the full water level WS when the washing water tank 108 becomes full water in the washing water W2 to clean the toilet bowl. It has a backbreaker 114e. Therefore, even if the washing water is going to flow back from the toilet 10 side for some reason, the backwashing of the washing water to the washing water tank 108 can be easily and surely prevented by releasing the atmosphere of the pipe by the vacuum breaker 114e. In addition, the communication pipe passage 114d at the end of the pipe 114 of the pipe 114 is tightly connected to the connecting hole 19 of the washing water feed passage 18 at a position higher than the full water level WS.

The branch pipe 110b is connected to the ball tap 115 in the tank, and supplies the washing water to the washing water tank 108 in accordance with the opening and closing of the ball tab 115. The ball tab 115 is connected to one end of the fertilizer support 116 and the other end of the support rod is connected to the fertilizer 117. The fertilizer 117 is disposed in the small tank 118 attached to the upper portion of the washing water tank 108. The top of the small tank 118 is open. A small diameter through hole 118a is formed in the bottom wall of the small tank 118. Therefore, because the jade 117 is moved up and down by the amount of water (water level) in the small tank 118, and the ball tab 115 is opened and closed in conjunction with the up and down of the jade, the washing water tank 108 has a predetermined high water level. Is maintained at (WS).

The jet pump 113 blows toward the piping 114 which arrange | positions the washing water (tap water) supplied from the piping 112 opposingly. The washing water sprayed in this way enters a throat of the lower end of the pipe 114, and at that time, the tank washing water in the washing water tank 108 is swept into the throat. In this way, from the pipe 114, the fractionated water subjected to the speed increase is supplied to the rim raceway 16 after passing through the washing water supply passage 18. Thereafter, the washing water is discharged from each of the water jetting holes in the rim raceway 16 as described.

In addition, the tap water pressure (primary side pressure) at the time of supplying the washing water is the total amount of washing water (about 4.5 to 6 liters) used for flushing the toilet and the amount of washing water supplied to the jet pump (about 18 to 25 liters). It is set in consideration and ends with a low primary feed water pressure of about 0.098 MPa (about 1 kgf / cm 2).

The water supply stop is as follows. When the running water RS in the toilet bowl 12 is sucked and the toilet bowl 12 is empty and the siphon stops, the water level of the washing water W2 in the washing water tank 108 is increased by the jet pump 113. It becomes below the level and the flow increase action of the jet pump 113 stops by suction of air. Thereafter, the tap water discharged from the injection nozzle 131 reaches the rim 14 through the pipe 114 and is supplied to the toilet bowl 12. As a result, tap water flows into the empty toilet bowl part 12 and the running water RS accumulates to the water level determined as the top bank 30.

The flush valve 111 automatically closes when a predetermined amount of tap water flows. As a result, the supply of tap water to the jet pump 113 is stopped, and the operation of the jet pump 113 is stopped. As described above, the stop timing of the flush valve 111, that is, the timing of stopping the tap water supply, is adjusted so as to estimate when the flushing water RS reaches the above water level in the toilet bowl 12. In this timing adjustment, the flush valve 111 is designed and manufactured so as to stop at a timing based on the water volume, the flow rate increase by the jet pump 113, the total amount of water used for cleaning the toilet, and the like.

Since the washing water W2 is discharged from the washing water tank 108 by the operation of the jet pump 113, the water level of the washing water W2 in the washing water tank 108 is lowered. As the water level of the washing water W2 in the washing water tank 108 decreases, the water level of the washing water W2 in the small tank 118 also decreases. In this case, since the washing water W2 in the small tank 118 gradually flows into the washing water tank 108 through the small diameter through hole 118a formed in the bottom wall, the washing water W2 in the small tank 118 The rate of decrease of the water level is smaller than the rate of decrease of the level of the washing water W2 in the washing water tank 108. Therefore, since the jade 117 descends at a small descending speed, the ball tap 15 is delayed in supplying the washing water to the jet pump 113 and is modified. The dropping speed of the jade 117 depends on the washing water passing speed of the through hole 118a, that is, the diameter of the through hole, so that the opening timing of the ball tab 115 can be adjusted by adjusting the through hole diameter. In the present embodiment is as follows. In other words, when the operation of the jet pump 113 stops after closing the flush valve 111 and the cleaning of the toilet 10 is finished, the diameter of the hole of the through hole 118a is lowered to a predetermined level. Adjusted. Therefore, at approximately the same time as the completion of the toilet bowl cleaning, the ball tap 115 is changed and water supply and supply of the washing water to the washing water tank 108 is started. After that, the washing water tank 108 is washed with water at the full water level WS. It is set as the storage state of (W2).

Next, the effect obtained by the toilet 10 in which the said washing water supply device 100 was built | coated is demonstrated. The toilet to be compared is a conventional tank type siphon trap toilet, which has a siphon trap with a substantially uniform pipe furnace area, and causes water flow to turn by discharge of the washing water to the toilet bowl. In the comparative test, the general particulate residue test and the PP (polypropylene) ball residue test were performed to show the dirt discharge capacity. In this case, in the particulate residual test, about 2500 pieces of fine particles having a particle diameter and about 4.5 mm were floated in the running water to wash the toilet in this state. In this test, it is said to be capable of discharging wastes if there are less than 125 particulate residues. In the PP ball residual test, 100 bowls of PP balls having a particle diameter and approximately 19 mm were floated to wash the toilet in this state. In this test, if the PP ball residue is less than 25, it is said to be capable of discharging dirt. The test was performed by changing the total amount of water (target value) of the toilet 10 of the present example and the comparative toilet. Fig. 22 is an explanatory view for comparing and explaining each flow rate of water supply to the toilet bowl part, inflow to the bowl part, and flushing water discharge from the trap with respect to the toilet to be compared with the toilet 10 of the present embodiment; It is explanatory drawing which shows the result of the evaluation test performed with respect to the toilet 10 and the said comparative example toilet.

As is clear from Figs. 22 and 23, the toilet 10 of the present embodiment has a result of the evaluation test despite the fact that the water supply flow rate to the toilet bowl part, the inflow flow rate to the bowl part, and the flushing water discharge flow rate from the trap are small flow rates compared to the comparative toilet. Was significantly higher. That is, according to the toilet 10, the washing | cleaning ability can be improved especially by the total amount (about 6 liters) of washing | cleaning state that the effectiveness effect of water saving is high. In this embodiment, since the above-mentioned siphon action is reliably occurring, strong dirt and flowing water are generated, and the first mainstream S1 and the second mainstream S2 are substantially parallel to each other in the same rotational direction. This can be said to be because the pushing of the swirl flow based on the high efficiency takes place. Therefore, according to the toilet of the present embodiment, it is possible to exhibit a high dirt discharge capacity. Although the occurrence of the siphon action was observed in the comparative toilet, the suction force of the siphon action and the pushing efficiency due to the swirl flow were not superior to the toilet of the present embodiment from the difference of the results in the particulate residue test. In addition, regarding the PP ball residual test, since it was confirmed that high dirt discharge | emission capability was obtained as mentioned above, implementation was abbreviate | omitted.

Subsequently, when the fine water residual test and the PP ball residual water test were carried out for a quantity (5 liters) less than the total amount of the current washing water, according to the toilet 10 of the present embodiment, all of the washing ability was higher than that of the comparative toilet. . This result also shows that in the present embodiment, since the above-mentioned siphon action is reliably occurring, strong dirt and water suction force are active, and the first mainstream S1 and the second mainstream S2 are substantially parallel to and rotate in the same manner. It can be said that the pushing of the swirl flow based on the confluence in the direction acts with high efficiency. In particular, it was possible to reduce the remaining PP ball count in the flowing water while being a small amount of the washing water supply of 5 liters (substantially about 4 liters). This can be said to be the result of pushing of the swirl flow based on the confluence of the 1st mainstream S1 and the 2nd mainstream S2 in substantially parallel and confluence in the same rotation direction, and is working with high efficiency.

Then, the pushing efficiency of the swirl flow was compared. That is, the Example toilet and the comparative toilet were compared without the siphon trap without changing the flushing water supply characteristics of the toilet bowl and the flow channel, and compared with respect to the pushing efficiency of the swirl flow. Moreover, the P pipe of the wall drainage structure was connected to the upper end of the riser part 24 by switching to the siphon trap. 24 is an explanatory diagram showing a toilet of the present embodiment without a siphon trap, and FIG. 25 is an explanatory diagram showing a comparison result between an exemplary toilet and a comparative toilet with respect to the pushing efficiency of swirl flow. The comparative test was done with respect to the PP ball residual test.

As shown in FIG. 24, the toilet for confirming the swirl flow pushing efficiency is removed from the toilet 10 of the above-described embodiment by removing the pipeline after the top bank 30 and replacing the siphon trap with drainage for wall drainage. The socket 170 is mounted tightly. Since the siphon action does not occur in this way, in the toilet 10 shown in figure, the dirt conveyance capability is determined only by the pushing efficiency of a swirl flow.

As shown in FIG. 25, according to the toilet 10 of the present Example, the washing | cleaning ability (PP ball injection efficiency) higher than a comparative toilet can be exhibited. This result also can be said in the present embodiment because the pushing of the swirl flow based on the confluence of the first main stream S1 and the second main stream S2 is substantially parallel and joined in the same rotational direction. have.

This uses the same siphoning action as the toilet of the wall drainage means using the drainage socket as shown in FIG. 24, because in the toilet 10 producing the swirl flow, a high pushing efficiency can be obtained by the swirl flow. By applying the swirl flow of this embodiment in the toilet of the structure which does not mean that high washing | cleaning ability is obtained. Moreover, even if it is not limited to the wall drainage means as shown in FIG. 24, even if it is connected to the pipe for upper drainage using the curved drainage socket, applying the swirl flow of a present Example can obtain high washing | cleaning ability.

In this embodiment, the high washing ability as described above can be exhibited by supplying the washing water with a small flow rate. When the quantity of water supplied to the toilet was checked, the amount of water supplied to the toilet 10 of this example was about 70 liters and about 150 liters on the comparative toilet. In such a low flow rate, the remaining air of the siphon trap cannot be extracted from the trap conduit at the beginning of washing, and the low flow rate has not been adopted in the existing toilet. However, in the present invention, on the basis of the novel idea of not discharging all of the remaining air at the beginning of cleaning, high-capacity in low-water supply is completed.

In conventional toilets (comparative toilets), in order to discharge all remaining air at the beginning of cleaning, the flushed water is subjected to high water washing, that is, to supply washing water at a large flow rate. For this reason, the sound by washing water supply and the sound of discharge of residual air were also loud. However, in the present embodiment, since it ends with the water supply of the washing water at the small flow rate, the portion and the above sound are reduced, thereby improving the static. According to the result of the sound collector, the toilet 10 of the present embodiment was able to reduce the loudness of about 5 to 10%. In the case where the total amount of the washing water was about 4 liters, about 59db was obtained in the comparative example toilet compared to about 66db. In the case where the total amount of the washing water was set to about 5 liters, about 67 db could be set to about 63 db according to this embodiment.

Moreover, in embodiment of this invention, it is also possible to set it as the wash water water supply using the head pressure, changing to the above-mentioned washing water supply device 100. FIG. 26: is explanatory drawing for demonstrating the toilet 10 of the modification which incorporates the wash water storage tank.

As shown in the figure, in the toilet 10, the storage tank device 150 for the washing water is stored in the appliance storage unit 11, and the washing in the tank is carried out in the washing water feed passage 18 through the water supply pipe 151 from the lower surface of the tank. Water the water. As described above, the washing water supplied to the washing water feed passage 18 flows into the rim raceway 16 and is discharged from the water discharge holes such as the base first water discharge hole 41 to the toilet bowl 12. Thereafter, washing water is pushed in the swirl flow by the confluence of the first main stream S1 and the second main stream S2 in substantially parallel and in the same rotational direction, and the siphon action is performed by the siphon trap 20. Causes Therefore, also in the toilet 10 using the storage tank apparatus 150, the effect of a small amount of the said washing water total amount can be acquired.

In this toilet 10, the washing | cleaning water flow volume which flowed into the flowing water RS is set to the head pressure h obtained by the full water level surface of the tank washing water which the storage tank apparatus 150 stores. Also in this toilet 10, since the discharge of all the air in a trap is not needed in the beginning of washing | cleaning, it ends with washing water feed water in a small flow rate. Therefore, the storage tank device 150 is sufficient to ensure the head pressure (h) as much as possible to achieve a water supply of about 70 liters / min. Therefore, it is preferable to set the height of the storage tank device 150 to about 1/2 to 2/3 as compared to the conventional washing tank water-saving toilet (about 6 liters of water-saving target). Improvement and freedom of design can be aimed at.

Thereafter, as described above, even in a situation where air remains in the uppermost part 70 of the inner wall of the top duct 26 or air swells in the lower surface of the tongue 71, the siphon action is caused by water supply of the washing water at a small flow rate. The manufacturing process of the toilet 10 which produces continuation is demonstrated. FIG. 27 is an explanatory diagram for explaining a casting state when manufacturing the toilet 10.

As shown in the figure, the toilet 10 is a toilet body casting including a toilet bowl part 12 or a ball bottom part 13, a toilet body BH for supporting them, and an apparatus storing part 11 in a casting state before the firing. BK), a rim casting (RK) comprising a top duct casting (TK) of the upper half of the top duct 26, a front wall of the rim 14 and the toilet seat 11 subsequent thereto, It is a terminal pipe casting (MK) which becomes the terminal pipe part 74. As shown in FIG. In this case, the top duct casting part TK is a rising duct part 24 in a wall surface portion of the curved duct of the top duct part 26 shown in Figs. ), That is, the casting of the wall portion of the predetermined range from the joining position of the rising pipe portion 24 and the rear inclination portion 63 partitioning the toilet bowl portion 12 to the descending pipe portion 28 and the connecting portion. . The toilet 10 is manufactured by molding each of these castings in advance, and bonding and firing each casting as described below.

FIG. 28 is an explanatory view illustrating the shape of mold molding of end pipe casting (MK), and FIG. 29 is an explanation of the shape of molding when the end pipe is molded together with a toilet cast pipe including a siphon trap pipe. It is also.

As shown in FIG. 28, a female mold 200 and a male mold 2110 are used. These two molds are suction molds formed from porous members, and deposit slip on each mold surface. The female mold 200 has a normal user recess portion 201 in the center, and has a release element 202 formed on the upper edge of the mold. The male mold 210 has a convex portion 211 protruding in an elliptic shape from the upper surface, and a tip convex portion 212 protruding in a circular shape from one end side of the convex portion, and a female mold 200 at the upper edge thereof. Has a release convex portion 213 fitting to the release element 202.

When both molds are molded so that the tip convex portion 212 flows into the user concave portion 201, the user concave portion 201 and the convex portion 211 as shown in Fig. 28 (b) and Fig. 28 (c) of the cross section along the line xx. Cavity (MKK) is formed between the mold surfaces.

Subsequently, slip is introduced from an injection port not shown in the cavity MKK, passes through suction of each mold, and slip is deposited on the mold surface of each mold, whereby it is ground. At this time, the portion of the cavity (MKK) in contact with the mold surface of each mold is filled with a landing slip having a thickness of about 100 mm, and the remaining portion has a fluid slip. This flow-shaped slip is discharged to the outside of the vacancy hole and not dried, and then dried to remove moisture from the cavities slip of the cavity. As a result, since the so-called soil clamping is completed, the above two molds are formed. Then, the end cup casting MK of the cylindrical cup shape corresponding to the end pipe part 74 before baking is completed. In this case, the end face of the tip convex portion 212 is joined to the bottom of the user recess 201 in the above cavity, and the end pipe casting (MK) has a circular shape that mimics the outer diameter of the tip convex portion 212 on the bottom thereof. It has a through hole 74mk. In the end pipe casting (MK), the outer wall shape is a cylindrical shape that mimics the inner wall shape of the user recess 201, and the inner wall shape is an elliptic shape that mimics the outer wall shape of the convex portion 211. That is, the inner and outer wall shapes can be made different. Further, the through hole 78mk in the end pipe casting MK becomes the through hole 78 before firing, and becomes the lowermost shelf portion 80 excluding the through hole 78mk.

By the way, when forming the end pipe part like a toilet casting containing a siphon trap pipe | tube, the left and right side mold | types 215 and 216 for toilet casting molding are used, as shown to FIG. 29 (a). Then, in the casting part corresponding to the end pipe part, the deposition deposition of the slip becomes one layer, so that the inner wall shape of the casting part does not become a shape (circular shape) that mimics the outer wall shape reflected by the mold shape. The inner and outer wall shapes cannot be different.

FIG. 30 is an explanatory diagram for explaining a mold used for mold molding of the top conduit portion casting (TK), and FIG. 31 is an explanatory diagram for explaining a mold molding of the top conduit portion casting (TK).

As shown in FIG. 30, the upper mold 220 and the lower mold 230 are used for molding the top pipe casting (TK). Also in the upper and lower molds, it is a suction type made of a porous member, and slip is deposited on each mold surface. The upper mold 220 has a recessed portion 221 recessed in a shape that defines the outer wall shape of the top pipe part casting TK corresponding to the wall portion in the top pipe part 26. It has a release element 222 used in combination. The lower mold 230 has a convex portion 231 protruding in a shape that defines the inner wall shape of the top pipe casting (TK), and the left and right edges of the lower mold 230 depressurizes to the release element 222 of the upper mold 220. Has 223.

When these molds are joined so that the convex part 231 opposes the recessed part 221, as shown in FIG. 31, the cavity TKK is formed between the mold surface of the recessed part 221 and the convex part 231. As shown in FIG.

Subsequently, slip is introduced from an injection port (not shown) to the cavity TKK, and the slip surface is deposited, grounded, dried, and dried on a mold surface subjected to suction of each mold. Because of this drying, the so-called soil clamping is completed in the cavity, and the above two molds are subsequently formed. Then, the normal channel part casting (TK) equivalent to the said wall surface part before baking is completed. Since the inner and outer wall shapes of the top pipe casting part TK formed in this way are defined by the shape of the mold surface of the upper and lower molds and the convex portions of the upper and lower molds, the inner and outer wall shapes can be varied, and the degree of freedom in design is increased. In addition, since the inner and outer wall surfaces of the top duct casting part (TK) can be made into the casting surface on the side where they are in close contact with the mold surface and deposited and deposited, the wall surface becomes unusable unevenness.

It is explanatory drawing explaining the shape of the metal mold | die of rim casting RK.

As illustrated, the upper mold 240 and the lower mold 242 are used for molding the rim casting RK. Also in these two upper and lower molds, it is a suction mold which consists of a porous member, and slip is deposited on each mold surface. The upper mold 240 has a shaped surface that defines the outer wall shape of the portion including the upper half of the rim 14 and the front wall surface of the appliance storage portion 1l following the rim 14 and the rim opening main wall. The lower mold 242 has a mold surface having a shape defining a lower wall portion of the rim 14 and an outer wall shape of a portion including the front side wall surface and the rim opening bottom main wall. Then, when both molds are joined together, a cavity RKK is formed between the mold surfaces of the die mold, so slip is introduced from the injection port not shown in the cavity RKK and the slip to the mold surface which has been sucked by each mold is deposited. It is fleshed and banished and dried. In this case, in the above-mentioned cavity (RKK), slip is deposited on the mold surface of the upper and lower molds in one layer, and soil clamping is completed in the cavity by drying in this state. Therefore, thereafter, the above two molds are molded, and each of the water jetting holes such as the base first water jetting hole 41 and the left central water jetting hole 43, etc. described in the post-molding casting are drilled. Form. If so, the rim casting RK corresponding to the rim 14 before firing is completed.

Explanatory drawing which shows the shape of the cross section of the 34-34 line | wire in FIG. 36 is a schematic perspective view of the separation mold 260 used for metal mold | die of toilet bowl casting (BK), and FIG. 37 is a metal mold | die molding of toilet bowl casting (BK). 38 is a schematic perspective view of the separation mold 270 used, FIG. 38 is a schematic perspective view of the side mold 280 in one direction used for mold molding of the toilet body casting (BK), and FIG. 39 is an apparatus storing part of the toilet 10. 11) It is explanatory drawing which shows the shape of the metal mold | die shaping | molding of the toilet bowl main body casting (BK) to the periphery, and the insider separation mold used for this.

As shown in FIG. 33, about the shaping | molding of the toilet body casting BK, first, the ball center mold 260 mentioned later is mounted and mounted so that the ball convex part 263 may go up to a metal mold | die formation object (not shown). Next, the side molds 280 on the left and right of the toilet are joined together to surround the ball center mold 260. At this time, the separation mold 270 is embedded in the central ball mold 260 as follows. Thereafter, the bottom mold 250 is molded to be mounted on the mold upper edge of the side mold 280. By doing in this way, the cavity BKK shown in FIG. 33 is formed in the inverted state from the mold surface of each metal mold | die. Moreover, each metal mold | die is a suction metal mold | die formed from the porous material, and a suction | gripping is made to adhere | attach a slip close to a metal mold | die surface by suction, and a slipping of a slip is caused. In addition, mold release recesses and convex portions used for molding are formed in each mold.

The cavity BKK comprises a toilet bowl part 12 or a ball bottom part 13, a toilet main body BH supporting them, and an apparatus storage part 11, and a siphon trap 20 except for the normal pipe part casting TK. For the formation of the toilet body casting (BK) including the pipeline of the) is divided as follows. That is, the cavity BKK is a cavity portion BKK2 surrounded by the mold surface of the ball center mold 260 and the bottom mold 250, the separation mold 270 and the bottom mold ( Cavity part BKK3 enclosed by the mold surface of 250, Cavity part BKK4 enclosed by the mold surface of the bottom mold 250, the side mold 280, and the ball center mold 260, and the ball center mold 260 And the cavity portion BKK5 surrounded by the mold surface of the separation mold 270. In addition, the cavity part BKK5 extends to the front and back direction from the surface of FIG. 33, and is continuous with the cavity part BKK2. The cavity portion BKK4 also extends in the front and back direction of the surface and is continuous with the cavity portion BKK2.

In order to form such a cavity BKK, the bottom metal mold | die 250 has the bottom part 251 used as a part as shown to FIG. 34, FIG. 35, and has the convex part 252 on the upper surface. The convex portion 252 has the convex portion 253 for forming the outer wall of the siphon trap 20 and the convex portion 254 for forming the lower wall of the device storage portion 11. Has a trap recess 255. The trap recess 255 is not only suitable for the outer wall shape of the downcomer 28 in the siphon trap 20, but also the outer shape of the lower surface side of the ball bottom 13 in the toilet bowl 12 and the toilet bowl ( 12) and the outer surface shape of the lower surface side of the lower body side BHK (see FIG. 27) of the lower body side BHK (refer to FIG. 27) of the lower part of the toilet body BH, and formed recessed so that these shapes may be defined. have. In this case, since the downcomer 28 is tapered as narrowed downward as shown in FIG. 11, even if the trap concave portion 255 is present, the downcomer 28 has a taper shape. As shown in the figure, a taper shape is obtained.

In the convex part 254, the upper surface shape is formed so that it may be suitable for the outer side shape of the lower wall of the lower wall of the apparatus storage part 11 so that a part of above-mentioned cavity part BKK4 may be formed. Also, the casting of the lower wall of the device storage unit 11 is formed by the iron portion 254, the side mold 280 and the ball center mold 260 to be described later.

As shown in Fig. 36, the ball center mold 260 has an upper upper edge portion 261, which is the upper edge of the next left and right side molds 280 and a joining portion, and the rim casting RK described above. A lower upper edge portion 262 for molding the joint portion is provided. The central ball mold 260 has a ball convex portion 263 and a rear convex portion 264 on the upper upper edge portion.

The ball convex portion 263 has a lower convex portion 265 formed in the concave shape to define the inner circumferential wall shape of the ball bottom portion 13 at the lower end thereof. The lower convex portion 265 has an end procedure portion 266 formed in conformity with the opening shape of the trap inlet 22 (see Figs. 2 and 3) of the upward conduit portion 24.

The convex shape of the ball convex portion 263 excluding the lower convex portion 265 is the entire inner circumferential wall shape of the toilet bowl portion 12, the upper circumferential wall 55 or the inclined portion 60 shown in Figs. The inclined portion 61, the lower shelf portion 62, and the rear inclined portion 63 are formed so as to define the shapes of the inner circumferential wall.

The rear convex portion 264 has an insertion element 268 to insert and paste the separation mold 270 described later on the side opposite the ball convex portion 263. In addition, the rear convex portion 264 has a lower end surface and a rear end surface (left side cross section in the drawing) so as to form part of the cavity portion BKK4 described above, and an inner surface side outer edge of the lower wall and the rear wall of the device storage portion 11. We are adapted to shape.

As shown in FIG. 37, the separation mold 270 joins the insertion part 271 that enters the insertion element 268 and the conduit forming convex part 272 in a bifurcated shape in the above-described ball center mold 260. It is provided by. In this case, the relationship between the insertion part 271 and the insertion element 268 is as follows. That is, by inserting the insertion portion 271 in the insertion element 268, the cavity can be formed so as not to rattle in the state in which the separation mold 270 is embedded in the inverted ball center mold 260, and a molding operation described later. The insertion part 271 and the insertion element 268 are adjusted in the dimension and shape so that the ball center mold 260 and the separation mold 270 may be formed independently.

In addition, an accessory mold 273 for forming trap openings is attached to the separation mold 270, and is attached to the lower end side surface of the conduit-forming convex portion 272 by magnets (not shown) embedded in both molds. The mold 273 is in close magnetic contact. In this way, the accessory mold 273 magnetically in close contact with the separation mold 270 is bonded without skiing to the end bottom part 266 of the lower convex portion 265 that is the ball center mold 260 in the mold completion state. In addition, in this state, the separation mold 270 leaves ski between the conduit forming convex portion 272 and the ball convex portion 263 opposite to this to form the ski as the cavity portion BKK5.

The conduit forming portion 272 is formed so as to conform to the conduit inner wall shape of the ascending conduit 24 in the siphon trap 20 to define the inner wall shape. In addition, the upper connection portion 274 of the conduit forming portion 272 and the insertion portion 271 is suitable for the pipe side wall shape of the top bank 30 and the tongue 71 of the top pipe portion 26, It is formed to define the shape. In the drawing of the insertion part 271, the lower end part 275 is covered with resin etc., and slip is not worn in the said area | region. In the case where the lower surface portion 275 is not covered with resin, the slip that has been landed on the portion may be performed after molding.

As shown in FIG. 38, the side metal mold | die 280 joins the toilet front side edge part 281 which becomes the mating part of right and left side mold parts, the toilet rear side edge part 282, and the bottom metal mold 250. As shown in FIG. The lower edge part 283 used as the lower edge part 284 used as a matching part with the side surface of the recessed part 254 of the bottom metal mold 250 is provided. And the side shape 280 makes the part enclosed by these edges the outer peripheral recessed part 285. In addition, the outer circumferential recess 285 is formed so as to conform to the outer wall shape of the toilet body BH including the device storage unit 11 so as to define the shape.

When these bottom molds 250 to side molds 280 are joined as shown in Fig. 33, the above described cavity BKK is formed on each mold surface. In this case, at the rear part of the toilet for forming the apparatus storing part 11, as shown in FIG. 39, a cavity portion BKK4 suitable between the side mold 280 and the rear convex portion 264 of the ball center mold 260. The inside separation molds 290 to 293 which have to imitate the shape of the main wall of the device storage unit 11 are formed.

In this way, when the cavity BKK for forming the toilet body casting BK is formed by the above-described molds and their mating, slip surface is introduced into the cavity BKK from the injection port not shown, and the mold surface undergoes suction of each mold. We deposit, slip, dry, and dry of slip to. In this case, in the above-mentioned cavity (BKK), slip is deposited and deposited on the mold surface of each mold in the cavity area (BKK1) and cavity area (BKK3) in one layer, and slip between the opposing mold surfaces in the other cab area. It becomes so-called double layering of the state filled with. And by the above-mentioned drying, the earthen clamping is completed in the cavity, the toilet body casting (BK) is completed in the cavity (BKK).

Here, the correspondence between the cavity parts and the casting will be described.

In the cavity part BKK1, besides the casting of the periphery circumference wall 55 and the inclination part 60 of the inner periphery wall area | region of the toilet bowl part 12, and the substantially whole area of the inclination part 61, In the toilet main body BH, casting of the site | part which extends from the lower surface side angle | angular part BHK or the toilet main body front to the left and right side walls is formed. In the cavity part BKK2, casting of the joint part of the inclination part 61 and the lower shelf part 62, or the whole area | region of the lower shelf part 62 and the ball bottom part 13 is formed. In the cavity part BKK3, in the siphon trap 20, the lower side side wall (the partition wall with the down side pipe part 28) of the rising line part 24, and the summit bank 30 and the tongue 71 which are continuous to this In addition, the curved pipeline 72, the intermediate pipeline 73 of the descending pipeline 28, the upper pipeline shelf 75 or lower pipeline shelf 77 and the outer wall portion ( A casting comprising 76) is formed. In the cavity part BKK4, the casting over the toilet wall surface surrounding the apparatus storage part 11 is carried out, and in the cavity part BKK5, the casting of the rear inclination part 63 which separates the toilet bowl part 12 and the rising conduit part 24 is carried out. Casting of the site | part connected to the whole area and the said inner peripheral wall of the toilet bowl part is formed, respectively.

In this way, after completion of the earthen clamping, the molds described above are formed. First, the bottom die 250 set at the top is raised and demolded, and a through hole 77mk is opened at the lower end of the downcomer 28 in the casting after demolding, as shown in FIG. Moreover, the lower end wall part periphery of this through hole 77mk becomes the lower pipe shelf part 77 shown in FIG. Thereafter, the plate received in order to support the casting of the demolded portion is alternately set the bottom mold 250, and the entire mold is rotated to return the molded toilet body casting BK to the normal direction. Thereafter, the ball center mold 260 positioned on the upper side is lifted by the rotation. In this case, the separation mold 270 has a relation (dimension, shape adjustment) between the insertion site 271 and the insertion element 268, which is described as being slightly constrained upward in the soil-cast casting in the cavity region BKK5. By means of the center ball mold 260 occurs alone.

After demolding the ball center mold 260, the separation mold 270 is lifted in an inclined direction toward the upper rear in the inverted posture of FIG. 33 to form this. At this time, the accessory mold 273, which is in close contact with the separation mold 270, is inclined in the soil-tight casting in the cavity portion BKK5, and thus the separation mold 270 is magnetically forced from being slightly restrained in the upper direction. Resisting without sticking to the accessory mold 273 in response to the adhesion force, and after the mold die 273 is demolded, the trap opening is precisely formed. Thereafter, the toilet body casting BK corresponding to the toilet body BH before firing is completed at the stage in which the insider separation molds 290 to 293 are formed, and thus, the gun required for the production of the toilet 10 formed here. Casting, ie, normal conduit casting (TK), rim casting (RK), end conduit casting (MK), and toilet body casting (BK) are integrated as follows.

First, the main line casting (TK) and the end pipe casting (MK) are joined to the toilet body casting (BK). In the joining of the top pipe portion casting (TK), as shown in FIG. 27, the pipe line of the siphon trap 20 is connected by connecting the up pipe portion 24 and the down pipe portion 28 in the toilet body casting BK. Stop it. In addition, in the joining of the end pipe casting MK, position alignment with the downcoming pipe part 28 is carried out in addition to the situation of the drain port at the place where the toilet 10 is shipped or the rough in. For example, the terminal pipe portion 74 before firing may be placed at a position where the terminal pipe portion 74 can be inserted into the drain hole according to the toilet seat installation. In addition, the joining of end pipe channel casting (MK) is mentioned later. Subsequently, the rim cast RK is joined to the upper edge of the toilet body casting BK, and then the left and right side molds 280 that are supporting the toilet body casting BK are removed. The casting of the toilet 10 thus obtained is dried and then fired under a predetermined firing condition to complete the toilet 10. After firing, the washing water feeder 100 is built. In the tank type shown in FIG. 26, the water supply pipe 151 and the storage tank apparatus 150 are built.

As described above, the production of the toilet 10 characterized by the occurrence and continuation of the siphon action in the water supply of the washing water at a low flow rate, which is not conventionally performed, in the casting state before firing, the top pipe portion of the siphon trap 20 In the curved line of (26), the top line part casting (TK) of the wall surface part which becomes the pipe wall surface facing the top bank 30 is connected from the connection part of the ascent line part 24 to the connection part with the descending line part 28. It does not exist in between. Accordingly, the toilet body casting BK may be formed by embedding the separation mold 270 for forming the inner wall, the top bank 30, and the tongue 71 of the upward conduit 24 in the ball center mold 260. . For this reason, the casting on the side closely deposited on the mold surface of the separation mold 270 can be used as the inner wall surface of the ascending pipe section 24 or the wall surface of the top bank 30 and the tongue 71. In addition to having no inner wall, it is possible to have a top bank 30 that has a protruding portion (sulting portion 71) in the conduit that cannot be formed in conventional mold molding.

The separation mold 270 for the formation of the upward conduit 24 or the top bank 30 is subject to the restriction that the ball center mold 260 needs to be inserted into the insertion element 268. Since the degree of freedom increases, the siphon trap line shape can be diversified. Therefore, according to the manufacturing method of this embodiment, a toilet with a diversified siphon trap pipe shape can be easily manufactured. In addition, the trap inlet 22 has a high dimension by joining the accessory mold 273 of the separation mold 270 and the lower convex portion 265 of the ball center mold 260 as the opening of the trap inlet 22. It can be formed with precision.

In addition, since the shape of the top bank 30 and the trap inlet 22 is defined by the separation mold 270 and the accessory mold 273, it depends on these shapes. It is possible to precisely obtain the height of the water in the ball portion flowing water (equivalent to the high and low difference between the top bank 30 and the upper end of the trap inlet 22).

Incidentally, the height of the seal defines the trap performance for backflowing small animals or dirt from the drain pipe, and therefore, a certain height is required. However, if this is too large, the moving distance of the dirt floating in the ball flowing water to reach the trap inlet becomes large and the discharge performance of the dirt decreases. Therefore, in order to ensure these functions, it is necessary to set the height of the seal in an appropriate range, so that the toilet and the manufacturing method of the present invention have the advantage that the toilet and the manufacturing method of the present invention have no other advantage.

In addition, the terminal pipe portion 74 inserted into the drain port in a separate state in the casting state, so that the entire toilet including the terminal pipe portion 74 after firing is a ceramic material and the terminal pipe portion (at the time of installation of the toilet 10) 74) can be inserted into the drain. Therefore, there is no need for pre-installation of the socket, the process for manufacturing the socket, and facility management, and the cost is advantageous. Further, since the end pipe portion 74 can be inserted into the drain, the siphon trap 20 having the end pipe portion 74 can be fitted to the drain hole means. The end pipe portion 74 is formed into the female mold 200 and the male mold 210 by adding the outer wall shape to a cylindrical shape having a good drainage insertion shape, and the inner wall shape is described. It is possible to obtain an elliptic shape suitable for storing the washing water for generating the action. Therefore, the added value of the toilet 10 itself can be increased.

Next, another Example is described. In this embodiment, the siphon action is generated by washing water supply at a large flow rate, and the pipe shape of the siphon trap is almost the same as the conventional one. 40 is an explanatory diagram for explaining the toilet 300 of another embodiment.

As shown in the figure, this toilet 300 has 20 A of siphon traps simply curved, and makes the up-coming part 24A face the toilet bowl part 12A via the trap inlet 22A. The rim 14 is similarly described for the toilet 10 described above and its shape, but it is assumed that the flushing water supply from the rim is about 100 to 150 liters.

The siphon trap 20A of the toilet 300 is inclined to the rear of the toilet from the trap inlet 22A, like the toilet 10, and the ascending pipe portion 24A and the ascending pipe portion 24A which form a conduit upward. It has a top conduit part 26A curved in the downward direction by connecting to the upper end, and a descending conduit part 28A descending by connecting to the top conduit part 26A. However, since the premise of washing water supply at the above-mentioned large flow rate is assumed, the top pipe portion 26A has only a curved convex top bank 30A that defines the flow level of the toilet bowl 12A. Each pipe | tube has the substantially same pipe cross-sectional shape. And even in the toilet 300, the distal end portion of the downcomer 28A is different from the toilet body caster BKA including the rim 14 and the toilet body BH and the siphon trap 20A in the casting state. The other body is endotracheal casting (MK). This end pipe casting (MK) is joined to the end of the downcomer part 28A of the toilet body casting (BKA) prior to casting firing, as in the case of the toilet 10. In addition, the siphon trap 20A is integrally cast and formed by the main body casting (BKA1), the bottom mold, the left and right side molds, and the ball center mold, and the rim casting (RK) of the rim 14 is combined with the toilet body casting (BK). It becomes a separate body.

Also in this embodiment, since the end pipe portion 74 inserted into the drain port is separately formed in the casting state, the above-described effect on the end pipe portion 74 described above can be played.

Next, the conjugation of the end pipe casting (MK) will be described. In the above-described embodiment, the end pipe portion 74 before firing, which has been made separately from the end pipe portion 74 in the casting state, can be inserted into the drain port. In this case, when making the lower end of the terminal pipe part 74 a height less than the bottom of a toilet bowl, a drainage outlet may be raised in the toilet upper surface. If a suitable sealing member (packing, etc.) is disposed between the drainage port raised from the upper surface and the terminal pipe portion 74 inserted therein, drainage leakage can be more reliably avoided. In addition to these, the following can be done. FIG. 41: is explanatory drawing explaining the corresponding shape to various rough ins, and FIG. 42 is explanatory drawing explaining the joint shape of the terminal pipe part 74 and a drain.

Rough people are said to be about 200mm in Japan, about 305mm in the US, about 305mm to 405mm in China, and about 405mm in Taiwan. In the above embodiment, the rough in is assumed and described in the case of Japan of about 20 mm, but the other rough in correspondence is as follows. FIG. 41A shows the rough 200 corresponding shape, FIG. 41B shows the rough 305 corresponding shape, and FIG. 41C shows the rough 405 corresponding shape. As shown in these figures, when the rough in Rf is different, the distance Brf between the rear end of the toilet and the end pipe portion 74 (in detail, the center of the water supply hole) is also different, and this distance Brf. Is determined according to the rough in Rf.

As shown in Fig. 41, when the rough in Rf is narrow, the end pipe casting MK is joined to the position by the toilet rear end side and fired together with the toilet body casting BK. As the rough in (Rf) becomes wider, the end tube casting (MK) is joined to a position shifted to the toilet bowl side and fired together with the toilet body casting (BK). That is, the joint position of the end pipe casting (MK) is adjusted according to the rough in. This adjustment is performed while the above-mentioned distance Brf determined according to the rough-in Rf. In addition, when the displacement amount toward the toilet bowl side is large as in the case of the rough in (Rf) 405, the end pipe line casting (MK) (terminal pipe section 74) to cover the water hole in the lower portion of the downcoming pipe section 28 The shape is also large for)). That is, a plurality of shapes of the end pipe casting (MK) (the end pipe passage 74) differ depending on the rough in (Rf) are prepared, and the joint position of the end pipe casting (MK) is adjusted according to the rough condition of the toilet seat installation area. This is done at the stage of toilet manufacturing. This makes it possible to commonize the toilet body casting BK, that is, the mold for molding the toilet body casting BK, which has a large mold size and complicated management of manufacture and storage. For this reason, it is preferable to prepare a mold (see Fig. 28) necessary for the production of end pipe casting (MK) from a small casting part, so that the mold production and its management cost can be reduced. In addition, the toilet obtained through the joining of end pipe casting (MK) and subsequent firing can be adapted to the ceramic toilet itself to be suitable for rough-in, which is one of drainage means.

As shown in Fig. 41 (c), when the end pipe casting (MK) (the end pipe part 74) is made large, the pipe part cannot be inserted into the drain port, but it is preferable to carry out as follows. In other words, when the annular sealing member surrounding the drain port is pressurized on the lower surface of the end pipe portion 74 to seal around the drain port, the washing water can be drained to the drain port without causing drainage leakage.

After that, the end pipe portion 74 is not inserted into the drain opening raised from the top, but the shape of the joint between the drain hole extending up to the upper surface and the end pipe portion 74 will be described. As shown in Fig. 42A, the first method arranges the drain connector HSC at the drain port HS up to the upper surface. The drain connector HSC has a tubular shape, and seals the terminal pipe portion 74 at the upper half of the grip portion UP. In addition, the drain connector HSC introduces the lower portion of the insertion portion DP into the drain port HS to achieve a drain seal. In this way, the terminal pipe portion 74 facing the drain port HS can be connected to the drain port HS via the drain connector HSC, thereby ensuring a drain seal. And, this drain socket (HSC) is a straight pipe shape that simply connected the holding portion (UP) and the insertion portion (DP) and its shape is unified, the handling is easy without error when installing the toilet bowl.

According to the second method, as shown in Fig. 42 (b), the end pipe portion 74 has a disk-shaped flange 74f on the lower end peripheral wall. In the manufacture of the terminal pipe portion 74 having such a shape, the female mold 200 shown in FIG. 28 may be divided up and down, and a cavity for forming the flange 74f may be formed on the divided mold surface. Then, prior to installing the toilet, the annular sealing member is inserted between the flange 74f of the end pipe portion 74 and the flange portion of the drain flange HSF by inserting a drain flange HSF having a flange at the top of the drain hole HS. (So-called P seal) is placed. The P seal may be pressed at the flange 74f of the end pipe portion 74 to seal the periphery of the drain port HS so as to avoid drainage of the drain. In this way, the joint with the drain port HS and the drain piece circuit wall can be performed by the end pipe part 74 itself, and since it does not require a bent socket etc., it is convenient.

As mentioned above, although the Example of this invention was described, this invention is not limited to said Example or embodiment at all, Of course, it can be implemented in various forms in the range which does not deviate from the summary of this invention.

For example, in the above-described embodiment, the discharge washing water from the base portion first water discharge hole 41 and the discharge washing water from the base portion second water discharge hole 42 are combined to generate the first mainstream S1. It is also possible to make the discharge washing | cleaning water from a single water jetting hole of the long hole shape as the 1st liquor S1.

Also, in the toilet 10 shown in FIG. 2 or FIG. 26, as shown in FIG. 43, the top pipe portion 26 has the same pipe road area as that of the rising pipe portion 24, and the rising pipe portion ( It is also possible to press the air of the top duct 30 by the washing water rising 24) to flow into the duct after the top duct. Even in this way, by providing the above-mentioned conduit structure of the downcomer part 28, through air sealing below tongue part 71, the division | segmentation of the water column by rising air, and the loss of the siphon action to pull are not produced. Therefore, the same effects as in the above embodiment can be played.

In addition, as shown in FIG. 44, the first water jetting hole 41a in the rear of the toilet seat and the second water jetting hole 43a in the front of the toilet right side are provided in the rim 14, so that both water jetting holes flow in the toilet horizontal plane. The position of the bilateral angle is centered on the center of RS). When the washing water is discharged from the water jetting holes, the first liquor S1 and the second liquor S2 join the flowing water RS by adopting a substantially parallel relationship between the bar and the flowing water RS shown in the drawing. By joining the two main streams, the swirl flow in the same rotational direction occurs in the flowing water RS. Therefore, this modification has the same advantages as the toilet 10 described above. In the second water discharge hole 43a, the rinse water channel 16 may be used to lead the washing water or the hose 43b may be used to lead the washing water. Moreover, in order to stabilize the 2nd mainstream S2 in this 2nd water discharge hole 43a, you may make it install the nozzle in the said water discharge hole.

The present invention is applicable to a method of manufacturing such a toilet having a toilet and a siphon trap for discharging the water supplied to the toilet bowl.
