Description

  The present invention relates to a connector applicable to a toilet system including an existing toilet device and a simple toilet device. In detail, while connecting the connecting bodies to be paired together in a rotatable manner, by providing an attachment port in a direction orthogonal to the connecting direction of these connecting bodies, the connecting direction can be freely set within the same plane. It can be selected so that it can be installed in a compact manner without bending even if it is bent.

  For elderly people who need nursing care and people who are physically disabled and have difficulty in going to existing toilets in the house, a portable simple toilet device as known in Patent Document 1 is connected to the existing toilet device. The development of a toilet system that can be used in the future is awaited.

  The portable toilet device is configured as a chair so that it can be installed in a living room, and it can be used by sitting on this chair. Between the existing toilet device, a vinyl hose can be used. Connected. FIG. 17 shows an example of this toilet system.

  The example shown in FIG. 17 is an example in which the existing toilet device 3 is installed facing the hallway 2 of the house 1. A toilet (toilet body) 4 and a water injection tank 5 are installed in the existing toilet device 3. In this example, a room 6 serving as a living room / bedroom is located along the corridor 2, and a bed 7 is placed in the room 6, for example.

  When a flush toilet device is used as the simple toilet device 10 that can be used in the room 6, the simple toilet device 10 is provided with water supply means and discharge means. The water supply means is connected to the water supply means in the existing toilet device 3, for example, the water injection tank 5, via the water supply hose 12. The discharge means is connected to the toilet body 4 of the existing toilet device 3 by a discharge hose 14, and filth and the like are directly discharged into the toilet body 4.

  When constructing such a toilet system, it is necessary to connect the existing toilet device 3 and the simple toilet device 10 using the water supply hose 12 and the discharge hose 14 as described above. The water supply hose 12 and the discharge hose 14 are both soft and bendable vinyl hoses. And it is necessary to arrange | position so that it may not interfere with walking as much as possible by the relationship arrange | positioned along the floor surface of a corridor. However, when the water supply hose 12 and the discharge hose 14 must be arranged along the corridor where the corridor is bent at 90 degrees, the water supply hose 12 and the discharge hose 14 are connected to the corridor at the bent portion of the hallway. It is difficult to dispose it along the corners of this area, and it must be bent greatly. If it is forcibly arranged along the wall surface of the bent portion, the water supply hose 12 and the discharge hose 14 may be crushed at the bent portion, which may hinder water flow in both the hoses.

  In addition, when the distance from the simple toilet device 10 to the existing toilet device 3 is relatively long, it becomes difficult to connect the toilet devices 3 and 10 with a single vinyl hose without an extension. Can be considered. In such a case, several vinyl hoses are connected and used. Patent document 2 etc. are known as a connector (hose joint) of a vinyl hose.

JP 2004-308404 A Japanese Utility Model Publication No. 6-14681

  By the way, when a vinyl hose is used as the water supply hose 12 or the discharge hose 14, as described above, the pipe diameter tends to be crushed at the bent portion such as a wall, and as a result, there is a possibility that water flow may be hindered. In particular, in the case of the discharge hose 14, not only sewage but also fluid such as filth flows in the inside thereof. Therefore, if the tube diameter is crushed, the liquefied material is liable to stay at the crushed and cause clogging. Conceivable. Furthermore, in the case of a simple toilet apparatus provided with a pressure feeding means, if the pipe diameter is crushed, the pressure feeding force in the pressure feeding means for pressure feeding the fluid must be increased. Even when a hard plastic supply / discharge pipe is used in place of the vinyl hose, it cannot be bent and disposed at an acute angle.

  Therefore, it can be said that it is a good idea to use a plurality of vinyl hoses equipped with a connector as the water supply hose 12 or the discharge hose 14. However, even when the water supply hose 12 or the discharge hose 14 is configured using a hose joint as disclosed in Patent Document 2, the collapse of the vinyl hose at the bent portion such as the wall is still eliminated. I can't.

  In particular, in the case of a connecting tool as disclosed in Patent Document 2, the connecting direction of the connecting tool itself and the extension direction (leading direction) of the hose connected to the connecting tool are the same. It must be a simple connection. For this reason, when using this connector, it must be disposed avoiding bent portions such as walls and the vicinity thereof, and there is a disagreement that limits the degree of freedom in layout design. From such a point of view, it is desired to develop a connector that can freely change the connecting direction of the hose so that it can be applied to a bent portion.

  Therefore, the present invention solves such a conventional problem, and particularly enables the paired coupling tools to be pivotably coupled to each other, and the hose coupling direction to be freely selected within the same plane. By making it possible, the present invention proposes a connector that can be used even in a bent portion or the like. By applying such a connector to a water supply hose or a discharge hose, even if there is a bent part in the route of the water supply hose or the discharge hose, the hose is crushed, and the arrangement along the wall is possible. The toilet system that made it possible can be constructed.

In order to solve the above-described problem, a connector according to the present invention described in claim 1 includes an opening provided in a connector body,
An on-off valve that is normally biased to close the opening;
A locking recess provided in the connecting body main body, and rotatably locking the connecting body that forms a pair;
A rotation locking portion provided on a part of the periphery of the locking recess;
It consists of the attachment port provided in the said connection body main body facing the direction orthogonal to the opening direction of the said opening part, It is characterized by the above-mentioned.

Further, the connector according to the present invention described in claim 2 is provided with an opening provided in the connector body,
An on-off valve that is normally biased to close the opening;
A locking projection provided on the connector body;
A rotation locking groove provided on a part of the periphery of the locking convex portion, and the rotation locking portion provided on a pair of connecting members rotatably locks;
It consists of the attachment port provided in the said coupling body facing the direction orthogonal to the opening direction of the said opening part, It is characterized by the above-mentioned.

Moreover, the connector according to the present invention described in claim 7 is a connector constituted by a pair of connectors,
One connected body is
An opening provided in the connector body;
An on-off valve that is normally biased to close the opening;
A locking recess provided in the connector body;
A rotation locking portion provided on a part of the periphery of the locking recess;
It consists of an attachment port provided in the connecting body main body facing the direction orthogonal to the opening direction of the opening,
The other connected body is
An opening provided in the connector body;
An on-off valve that is normally biased to close the opening;
A locking projection provided on the connector body;
A rotation locking groove provided on a part of the periphery of the locking projection;
It consists of an attachment port provided in the connecting body main body facing the direction orthogonal to the opening direction of the opening,
By fitting the locking projection provided on the other coupling body into the locking recess of the one coupling body, the opening is opened by the interaction between the on-off valves, The pair of connecting members are connected to each other so as to be freely rotatable.

  In this invention, a connector is comprised by a pair of connection body. One connection body is a female type (socket), and the other connection body is a male type (plug). The female-type coupling body is a disk-shaped coupling body (housing as a housing), and a flange-shaped opening having a relatively large opening area is provided at a substantially central portion inside the coupling body. It is a locking recess that is continuous with the opening and is open at one end. By enlarging the opening area, even a fluid can pass without stagnation. The other end side of the opening is an empty room (chamber) provided with an on-off valve.

  The opening is opened and closed by opening / closing operation of the opening / closing valve. The on-off valve is normally urged by the urging means so as to close the opening. It is opened when the paired male connector is connected.

  A spring is used as the urging means, and a cover body that covers the spring is provided. The cover body has a bellows shape so that it can expand and contract in accordance with the expansion and contraction of the spring. A cover body is provided to prevent the fluid from adhering to the spring when the fluid passes through the chamber.

  At the center of the on-off valve, a ridge that protrudes toward the locking recess is provided. The ridges face the same ridges provided on the paired connecting body, and the openings are forcibly opened by the mutual pressing force due to the contact between the ridges. Is done.

  A rotation locking portion is provided on a part of the periphery of the locking recess. The rotation locking portion is constituted by a sphere (such as a ball ball for ball bearings) scattered on the circumference, and a part of the sphere is attached so as to freely advance and retract so as to protrude from the inner surface of the locking recess. The movement of the sphere is regulated by a slide ring provided on the outer peripheral surface of the locking recess (advance and retreat to the locking recess inner surface side). The slide ring is biased in a direction of pressing the sphere by a spring. This bias is released by retracting the slide ring.

  An attachment port is provided in communication with the chamber. This attachment port is formed in a plane perpendicular to the connecting direction of the paired connecting members. Since a pipe body such as a vinyl hose is connected to the attachment port, the outer diameter matches the inner diameter of a commercially available pipe body such as a vinyl hose.

  The male connector is similarly configured. However, since the configuration is a pair, the locking convex portion corresponds to the locking concave portion, and the locking groove portion corresponds to the rotation locking portion. The locking projection is selected to have an outer diameter and length that can be fitted into the locking recess. The locking groove is an annular groove having substantially the same arc as that of the sphere. An attachment port is formed in the surface orthogonal to the connection direction (opening direction) of a connection body similarly to a female type connection body. By forming the attachment port in a plane orthogonal to the connection direction of the connection body, the attachment ports formed in the two connection bodies are formed in the same surface and are provided so as to be parallel to each other. . There is no slide ring.

  When the male connector is connected to the female connector, the locking protrusion is fitted into the locking recess with the slide ring retracted. When both are completely fitted, the spherical body is fitted in the locking groove. In this state, when the hand is released from the slide ring, the slide ring returns to the original position. Since the sphere is pressed by the inner peripheral surface (projection inner peripheral surface) of the slide ring by the return to the original position, the connection state between the two is locked.

Since the fitting state of the male coupling body is locked by the sphere, the locking projection cannot be detached from the locking recess, but the movement in the circumferential direction is not restricted. As a result, the orientation of the other attachment port with respect to one attachment port can be freely set. Moreover, since one attachment port and the other attachment port exist in the same plane, when the bent portion is 90 degrees, the direction can be changed by 90 degrees. In other words, the hose can be bent 90 degrees through this connector without crushing the tube diameter of the hose. Therefore, when using the connector according to the present invention in a place where there is a bent portion, it is preferable to arrange the connector at the position of the bent portion. Therefore, when the connector is attached to a water supply hose or a discharge hose used in a toilet system, the water supply hose or the discharge hose can be disposed along the indoor wall.
The simple toilet device is not restricted to other configurations as long as it is a flush type. For example, it is possible to use a toilet device in which a toilet body is provided with filth pulverizing means and pressure feeding means for pumping the crushed filth.

  Also, in the toilet system, it is very convenient if it has a function that can detect the usage status of the toilet device and, when the usage status is detected, send a usage status signal to the response terminal device, for example. is there. By operating the notification means in the response terminal device according to the use state signal, it is possible to notify the person carrying the response terminal device (such as a caregiver or a caregiver) that the simple toilet device is being used.

  The connector according to the present invention is configured so that a pair of connected bodies can be connected to each other in a freely rotatable manner, and the connecting direction of the hose can be freely selected within the same plane.

  By doing so, it is possible to provide a connector that can be used even in a bent portion or the like. By applying such a connector to a water supply hose or a discharge hose, even if there is a bent part in the route of the water supply hose or the discharge hose, the hose is crushed, and the arrangement along the wall is possible. The toilet system that made it possible can be constructed.

  Then, the example which applied the connector concerning this invention to the toilet system is demonstrated in detail with reference to drawings.

  FIG. 1 is a cross-sectional view of an essential part showing an example of the present invention. The connector 60 according to the present invention includes a female connector (socket) 60A and a male connector (plug) 60B. The female-type connector 60A will be described.

  The female coupling body 60A has a flat coupling portion main body (housing) 61 having a disk shape, and the inside of the coupling portion main body is formed by an opening 63 formed at a substantially central portion thereof. The front chamber functions as a locking recess 62 and the rear chamber functions as an empty chamber 61a.

  The opening 63 is a flange having a relatively large opening (circular opening) provided so as to protrude into the coupling body. By enlarging the opening area, even a fluid, particularly a fluid, can pass through the opening 63 without stagnation.

  The rear chamber partitioned by the opening 63 is an empty chamber 61 a provided with an opening / closing valve 65. The opening 63 is opened or closed by the opening / closing operation of the opening / closing valve 65. Normally, the opening / closing valve 65 is urged by the urging means 66 so as to close the opening 63. The opening 63 is opened when the paired male connector 60B is connected.

  As the biasing means 66, a string-wound spring can be used. Therefore, a recess 61b for locking one end of the spring 66 is provided in the empty chamber 61a, and a recess 65b for locking the other end of the spring 66 is also provided in the on-off valve 65 facing the recess 61b. The spring 66 is mounted so as to be interposed between the recesses 61b and 65b.

  The outer peripheral surface of the spring 66 is covered with a cover body 67 so that the spring 66 is not exposed to the outside. The cover body 67 is configured in a bellows shape that can expand and contract in accordance with the expansion and contraction of the spring 66. A string spring (not shown) having a weak spring force is inserted inside the cover body 67 so that both ends of the cover body 67 are not separated from the recesses 61b and 65b.

  On the opening / closing valve 65, a portion located on the front chamber side is provided with a protruding strip portion 65a as shown. The protrusion 65a is provided at the center of the opening / closing valve 65 so as to protrude from the opening 63 toward the front chamber, and is an operating rod that functions as an opening / closing element of the opening / closing valve 65. The ridge 65a is acted to open the on-off valve 65 by a locking projection 165a described later.

  The front chamber side that is continuous with the opening 63 serves as a locking recess 62 having one end opened. The locking concave portion 62 is a cylindrical member for fitting and fixing a locking convex portion 162 to be described later, and a tapered through hole 62a holds a predetermined interval at a part of the circumference thereof. A plurality of holes are drilled. The plurality of through holes 62 a function as a part of the rotation locking portion 68. That is, the locking recess 62 and the rotation locking portion 68 constitute a ball bearing. The number of the through holes 62a varies depending on the size of the connecting body, but about 4 to 8 is appropriate.

  The rotation locking portion 68 is configured by a sphere corresponding to the through holes 62a scattered on the circumference. The spherical body 68 is formed into a tapered through-hole so that it does not fall into the locking recess 62 through the through-hole 62a, in other words, only a part of the spherical surface of the spherical body 68 is exposed in the locking recess 62. In addition, the inner diameter of each other is selected. The spherical body 68 can freely advance and retreat in the through hole 62a. As the sphere 68, a steel ball for a ball bearing (ball bearing), a plastic ball similar to the ball, or the like can be used.

  The movement of the spherical body 68 (advancing and retreating operation toward the inner surface side of the locking recess 62) is restricted by a slide ring 69 provided on the outer peripheral surface of the locking recess 62. The slide ring 69 includes an annular projecting portion 69a provided so as to project to the inner surface side of the front end portion thereof, and an annular recess for pressing release (pressing release recess portion) provided so as to continue to the annular projecting portion 69a. ) 69b and an annular pressing portion 69c provided continuously to the pressing release recess 69b.

  The slide length of the slide ring 69 is regulated by the annular protrusion 69 a and the stopper recess 62 b formed in the locking recess 62. This is because the annular projecting portion 69a slides within the stopper recess 62b.

  The annular recess 69b and the annular pressing portion 69c regulate and release the forward / backward movement of the sphere 68. Therefore, the slide ring 69 is moved in the direction of arrow a by a pressing spring (string spring) 71 interposed between an annular recess 70 formed on the outer peripheral surface of the connecting body 61 and an annular pressing portion 69c of the slide ring 69. A sliding force is always applied.

  When the slide ring 69 is slid in the direction of arrow a, the sphere 68 is pressed by the annular pressing portion 69c, and the forward and backward movement of the sphere 68 is restricted. Therefore, by sliding the slide ring 69 in the direction of the arrow b so that the sphere 68 faces the pressing release recess 69b, the pressing force on the sphere 68 is released, and the sphere 68 can freely advance and retreat. .

  A part of the outer peripheral surface of the vacant chamber 61a, that is, a direction orthogonal to the connecting direction with the male coupling body 60B, and a part of the outer peripheral surface of the vacant chamber 61a is connected to the vacant chamber 61a. The port 64 is formed integrally with the connecting body 61 that constitutes the empty space 61a. An end of a tubular body such as a hose is attached and fixed to the attachment port 64. Therefore, the outer diameter of the attachment port 64 is selected to be an outer diameter that matches the pipe diameter of an existing pipe body such as a vinyl hose.

  An annular packing material 72 for preventing water leakage is attached to each of the surfaces where the opening 63 and the on-off valve 65 are in contact with each other, and the surface of the opening 63 facing the locking recess 62 is also prevented from leaking. An annular packing material 73 is mounted.

  The male-type coupling body 60B fitted to the female-type coupling body 60A configured as described above has a paired structure. Therefore, the male coupling body 60B is composed of the following members.

(1) Link body 161
This is a housing (housing) corresponding to the female connector body 61. The connecting chamber body 161 has a locking chamber 162 on the front chamber side and a vacant chamber (chamber) 161a on the rear chamber side.

(2) Locking convex portion 162
The locking convex portion 162 is a cylindrical body (annular cylindrical body) whose inside is a hole, and has an outer diameter that can be fitted to the inner peripheral surface of the locking concave portion 62. The size of the inner diameter is not particularly limited, but the size of the opening 163 provided on the base side is selected so as to be the same as the opening 63 of the female type. The length of the locking projection 162 is substantially the same as the depth of the locking recess 62. An annular packing material 173, which is also paired with the annular packing material 73, is attached to the tip of the locking convex portion 162 at a position facing the annular packing material 73 provided in the locking recess 62. In addition, water leakage from the locking convex portion 162 is prevented by the abutment between the two.

(3) Locking groove 175
A predetermined depth that engages with a part of the peripheral surface of the sphere 68 at a position that is a part of the outer peripheral surface of the locking convex part 162 and faces the sphere 68 that functions as the rotation locking part. An annular groove portion 175 having the shape is formed. Even if the forward / backward position of the sphere 68 is restricted, the radial direction of the sphere 68 is not restricted at all. Therefore, the engaging groove 175 is formed in an annular shape so that the engaging protrusion is fitted as described later. 162 can be fitted into the locking recess 62 in a state where it can freely move in the circumferential direction.

(4) Vacant chamber 161a and on-off valve 165
An open / close valve 165 that controls opening / closing of the opening 163 is provided in a vacant chamber (chamber) 161 a of the connecting body 161. The on-off valve 165 is also a valve body having a cross-section ridge, and a ridge portion 165a protruding from the center portion into the locking protrusion 162 is a ridge provided on the female-type coupling body 60A. It is in a position facing the part 65a. The length is also the same length as that of the ridge 65a.

  Between the opening / closing valve 165 and the bottom of the empty chamber 161a, a spring (biasing means) 166 having a chord shape for biasing the opening / closing valve 165 is interposed, and the opening portion is normally urged by the biasing force of the spring 166. Since it is pressed to the 163 side, the opening 163 is closed. The outer periphery of the spring 166 is covered with a cover body 167 having a bellows shape that can expand and contract. This is to prevent the fluid passing through the coupling bodies 60 </ b> A and 60 </ b> B from adhering to the spring 166.

  In order to lock and fix the spring 166, a locking recess 161b is formed in the bottom of the empty chamber 161a, and a locking recess 165b is also provided in the on-off valve 165.

  An annular packing material 172 for preventing water leakage is mounted on each of the surfaces where the opening 163 and the on-off valve 165 contact each other.

(5) Mounting port 164
In a part of the outer peripheral surface of the vacant chamber 161a, that is, in a direction orthogonal to the connecting direction (opening direction of the opening 163) with the female coupling body 60A, An attachment port 164 communicating with the vacant chamber 161a is formed integrally with the connecting body 161 constituting the vacant chamber 161a. Thereby, the mounting directions of the pair of mounting ports 64 and 164 are parallel to each other. Since the end of the tube body such as a hose is attached and fixed to the attachment port 164, the outer diameter is selected to match the tube diameter of an existing tube body such as a vinyl hose, similar to that of the female type. .

  The coupling tool 60 is configured by the pair of coupling bodies 60A and 60B configured as described above. FIG. 2 shows the connected state of both. In order to connect the male connector 60B to the female connector 60A, the locking projection 162 is used for locking in a state where the slide ring 69 is returned in the direction of the arrow b in the drawing to make the sphere 68 free. It inserts in the recessed part 62, and makes both fit. If the hand is released from the slide ring 69 in this state, the slide ring 69 moves in the direction of the arrow a in the figure and returns to the original position. At this time, the sphere 68 is pressed toward the locking groove 175 side. The portion 162 is locked to the locking recess 62.

  In this locked state, the ridges 65a and 165a of the on-off valves 65 and 165 are in a state of being opposed to each other and are in contact with each other. The on-off valve 65 is separated from the opening 63, and the other on-off valve 165 is also separated from the corresponding opening 163. As a result, the connecting bodies 60A and 60B communicate with each other. For example, when the connecting bodies 60A and 60B are combined with the attachment ports 64 and 164 positioned on the same side, as shown by the arrow c or the arrow d. The fluid can be circulated.

  Here, the connecting bodies 60A and 60B are locked in the connecting direction, but can be rotated in the circumferential direction of the locking convex portion 162. The connection angle between the ports 64 and 164 can be freely selected. Therefore, for example, as shown in FIG. 3, when the male coupling body 60B is rotated 180 degrees with respect to the female coupling body 60A, the fluid can flow from the bottom to the top of the paper or from the top to the bottom. .

  As described above, the connector 60 according to the present invention can freely adjust the direction of the outlet with respect to the inlet as long as it is within the same plane. Therefore, this connection tool 60 is suitable for application to a portion having a large number of bent portions. An example of the application will be described with reference to FIG.

  FIG. 4 is a conceptual diagram of the toilet system. In this way, the existing toilet apparatus 3 and the simple toilet apparatus 10 are substantially in the same plane, but the water supply hose 12 and the discharge hose 14 that connect them are not easily bent with the existing toilet apparatus 3 unless they are bent several times. The toilet device 10 cannot be connected. In the case of FIG. 4, there are at least two bent portions. The first is that the hose must be arranged along the hallway 2 when going out of the room 6 into the hallway 2. Secondly, since the corridor 2 is bent 90 degrees, the front and rear of the bent portion must be disposed along the wall.

  If the conventional water supply hose or discharge hose is used, the hose will be crushed at each of these bent portions. When a water supply hose or a discharge hose is connected and used, the conventional connecting tool connects the hose and the hose linearly, so that the angle cannot be adjusted at the connecting place and the hose is not crushed.

  When the connecting tool according to the present invention is used, no matter how many bent portions are in the same plane, if the connecting tool is prepared in accordance with the bent portion, it can be disposed along the bent portion. In the example of FIG. 4, the arrangement along the two bent portions can be realized by connecting at least three hoses. That is, between the existing toilet device 3 and the simple toilet device 10 using the first to third water supply hoses 12 (12A to 12C) and the first to third discharge hoses 14 (14A to 14C). Connected. An example of these water supply hose 12 and discharge hose 14 is shown in FIG.

  When connecting the connector according to the present invention to the hose, it can be applied to any hose regardless of the use of the hose.

  In the present invention, at least two types of common hoses 300 are prepared. A common hose 300A shown in FIG. 5A has a well-known connector (male or female) 304 connected to one end, for example, the left end of a hose 302, and a female connector of the connector 60 according to the present invention to the right end. The 60A or male connector 60B is connected. FIG. 5A shows a case where a female connector 304 and a female connector 60A are mounted and fixed.

  Moreover, in the common hose 300B shown to FIG. 5B, the connection tool 60 which concerns on this invention is connected with both ends. In this example, the male connector 60 </ b> B is attached and fixed to both ends of the hose 306.

  As shown in FIG. 4, the water supply hose 12A, the discharge hose 14A connected to the simple toilet device 10 and the water supply hose 12C and the discharge hose 14C connected to the existing toilet device 3 are all the common hose 300A shown in FIG. 5A. Is used. This is because the connection with the simple toilet device 10 uses a well-known connection tool 304. Similarly, connection with the existing toilet apparatus 3 is because a well-known connector 304 is used.

  On the other hand, the common supply hose 300B shown in FIG. 5B is used for both the water supply hose 12B and the discharge hose 14B located in the middle. This is because both use the connector 60 according to the present invention.

  FIG. 6 is an enlarged view when the corridor 2 is applied to a portion bent 90 degrees, and as shown in FIG. 7 viewed from the direction of the arrow p, a female-type connection provided on one common hose 300A. The body 60A and the male coupling body 60B provided on the other shared hose 300B are coupled to the floor surface 330 in the vertical direction. Since both the attachment ports 64 and 164 extend in a direction perpendicular to the connecting direction, both the hose 302 and the hose 306 can be led out in a direction parallel to the floor surface 330. As shown in FIG. 6, the attachment ports 64 and 164 have a connection angle of 90 degrees.

  By adjusting the connection angle to 90 degrees in this way, the shared hoses 300A and 300B can be disposed along the wall 312 of the hallway 2 without crushing the hose. The application example described above is merely an example.

  Common hoses 300A and 300B shown in FIG. 5 use hoses 302 and 306 having the same pipe diameter, but hoses having a pipe diameter corresponding to the application can also be used. This is because, as described above, the discharge hose 14 is a flow of fluid such as filth, so it is preferable to use a hose having a larger pipe diameter than the water supply hose 12. In that case, two types of connectors 60 having different sizes corresponding to the pipe diameters are used.

  Next, the simple toilet device 10 and the existing toilet device 3 that can be applied to the toilet system described above will be described with reference to FIG. As the simple toilet device, a portable device devised so that it can be used in a living room is illustrated, but a simple toilet device with a so-called warm water cleaning toilet seat with a butt cleaning function is preferable. In the following explanation, explanation of the equipment of the warm water washing toilet seat is omitted. The portable simple toilet device is applied to a Western toilet type.

  FIG. 8 is a cross-sectional view of an essential part showing an example of the simple toilet device 10. The toilet body 20 constituting the simple toilet device 10 has a funnel-like cross-sectional shape that is substantially the same as that of a normal flush toilet (Western-style toilet), but its overall shape is configured as a box shape. Not only a box shape but also a chair shape with an armrest may be used. In order to reduce the weight of the toilet body 20, the toilet body 20 is a molded product made of plastic in this example. You may shape | mold using other materials, such as earthenware. A toilet seat 21 is located on the upper opening side of the toilet body 20, and a toilet lid 23 is provided to close the toilet seat 21 and the upper opening.

The bottom portion of the toilet body 20 serves as trap water (reserved water) or filth reservoir 18.
A discharge portion 22 that communicates with the reservoir portion 18 and has a substantially “H” cross section is provided, and the discharge hose 14 is connected to the discharge port 27. Therefore, in this example, the connecting body 26 is provided on the back surface portion 20b of the toilet body 20, and an electromagnetic valve 24 that functions as an on-off valve inside the toilet body 20 is provided close to the connecting body 26. . The shape of the discharge portion 22 communicating with the reservoir portion 18 may be P-shaped, U-shaped, saddle-shaped, etc. in addition to the illustrated shape. The discharge portion 22 having a substantially “H” cross section is generally called an “S” trap.

  The electromagnetic valve 24 is controlled so as to open only when trap water (water containing dirt) in the reservoir 18 is discharged out of the toilet bowl, and is closed when the toilet is not in use. This is to prevent water leakage. Further, at the same time, waste is effectively discharged by the pressure of the air compressor.

  Near the upper part of the toilet body 20, a flush water supply port 28 is provided on the wall 18 a on the discharge side. A connecting pipe 30 is disposed between the connecting body 34 provided on the main body back surface portion 20 b and the water supply port 28, and an electromagnetic valve 32 is attached in the vicinity of the connecting body 34. This is because water supply from the water supply hose 12 connected to the connection body 34 can be controlled by the electromagnetic valve 32.

  A rubber-like water leakage prevention pipe 29 is inserted between the water supply port 28 and the wall surface 18 a so that water does not leak to the back space 20 a side of the toilet body 20.

  A crushing means 40 is provided at the bottom of the reservoir 18. The crushing means 40 is for crushing the filth and the toilet paper (hereinafter collectively referred to as filth) collected in the reservoir 18, and the crushed fluid is mixed with the trap water and discharged.

  The crushing means 40 can be constituted by a motor 42 and crushing blades 44, and in FIG. 8, only the crushing blades 44 are attached so as to face the pool portion 18. Therefore, the motor 42 is disposed on the bottom outer wall 19 side of the pool portion 18 and is attached and fixed to the toilet body 20 by a support 46 made of bolts or nuts. The rotating shaft of the motor 42 is water-tightly coupled to the bottom of the pool portion 18. The motor 42 may be fixed to the bottom plate 20c of the toilet body 20 instead of the bottom outer wall side of the pool portion 18.

  A control unit 50 composed of a CPU or the like is disposed on the bottom plate 20c. Each drive of the discharge solenoid valve 24, the water supply solenoid valve 32, the motor 42 and the like described above is controlled by the control unit 50 at a predetermined timing for a predetermined time. Further, as will be described later, when the control unit 50 detects the use state of the simple toilet device 10, it responds when a signal indicating the use state is transmitted or a response signal is received from a response terminal device (described later). A function for performing the processing is added.

  A power switch 52 for the control unit 50 is provided on the main body back surface portion 20b, and is an upper surface portion of the main body, and an open / close detection switch 55 for detecting opening / closing of the toilet lid 23 is provided on the lower surface of the toilet lid 23.

  On the upper surface of the toilet body 20, in this example, a notification unit 250 controlled by the control unit 50 is installed on the rear surface side of the toilet lid 23. In this example, a buzzer 252 and a notification indicator lamp 254 constitute a notification means 250 (see FIG. 11).

  The simple toilet device 10 further has the following structure. As shown in FIG. 8, the pulverized material for supplying predetermined compressed air to the reservoir 18 at a predetermined position below the water supply port 28 in the upper part of the back surface of the reservoir 18 in the toilet body 20. An opening / closing lid mechanism 245 for sealing the pressure feeding means 200 and the reservoir 18 is provided.

  The pressure feeding means 200 can be constituted by an air compressor, and the feed pipe 204 of the air compressor 200 is led out from the wall surface 18a to the accumulation portion 18 side through the mounting means 206. The attachment means 206 is provided above the surface of the trap water in the reservoir 18. The air compressor 200 is fixed to a mounting plate 202 provided in the back space 20 a of the toilet body 20. Instead of the pressure feeding means 200, compressed air can be taken in from the outside of the simple toilet body.

  A diameter-reduced portion 240 is provided in the upper inner peripheral wall of the upper portion of the pool portion 18 and slightly above the mounting position of the pressure feeding means 200. An opening / closing lid mechanism 245 is provided on the lower surface of the reduced diameter portion 240 so as to close the reduced diameter portion 240 and seal the pool portion 18.

  The reduced diameter portion 240 is configured as an annular flange portion, and the whole is provided so as to be slightly inclined toward the discharge portion 22 side. On the lower surface side of the reduced diameter portion 240, a rotary opening / closing lid mechanism 245 capable of closing the reduced diameter portion 240 is provided.

  In this example, the lid body 246 constituting the opening / closing lid mechanism 245 is provided, and one end of the lid body 246, the right end portion in the example shown in the figure, serves as a rotation shaft portion 247, and the rotation shaft portion 247 is a reduced diameter portion. It is pivotally supported with respect to the toilet body 20 so as to be positioned on the lower surface portion 241 of 240. This pivotal support is pivotally supported by the toilet body 20 in a watertight manner.

  The lid main body 246 is biased in a direction in which the peripheral surface thereof abuts on the lower surface edge 242 of the reduced diameter portion 240. In other words, the lid main body 246 has a shape along the lower surface edge 242, and usually the rotating shaft 247 and the wall surface of the lower surface 241 are sealed so that the inside of the reservoir 18 can be sealed by contacting the lower surface edge 242. A biasing spring 248 is wound between the two.

  When the simplified toilet device 10 is configured in this way, when the excrement falls on the lid body 246, the distal end side of the lid body 246 is opened by its own weight (see FIG. 9), and the excrement falls into the pool portion 18. To do. When the excrement falls, the lid body 246 is automatically returned to the original position (see FIG. 8) by the action of the spring 248 and the upper portion of the reservoir 18 is closed.

  Since the reduced diameter portion 240 is provided so as to be slightly inclined toward the discharge portion 22 side, the lid body 246 itself constituting the opening / closing lid mechanism 245 is also inclined and attached to the discharge portion 22 side. If the lid main body 246 is tilted and attached in this manner, the excrement dropped on the upper surface of the lid main body 246 does not remain and can be dropped into the pool portion 18.

  Thus, since the reservoir 18 is sealed by the lid body 212, the compressed air effectively acts on the reservoir 18 side. Since the crushed filth is a fluid, the fluid can be easily discharged through the discharge hose 14 together with the washing water if the compressed air is applied to the pool portion 18.

  Accordingly, the flow material does not stay in the discharge hose 14 (common hoses 300A and 300B). Since the springs 66 and 166 in the pair of coupling bodies 60A and 60B constituting the coupling tool 60 provided in the shared hoses 300A and 300B are both covered by the cover bodies 67 and 167, when the fluid passes therethrough The fluid does not adhere to the springs 66, 166, etc., and does not cause stagnation or clogging.

  Since the fluid is pumped in a state where the inside of the reservoir portion 18 is sealed, a relatively small compressor can be used as the air compressor used as the pumping means 200. Since the opening / closing lid mechanism 245 is used, when the filth is pulverized, it is possible to prevent the filth from scattering into the toilet main body 20, so that the toilet main body 20 does not become unsanitary.

  FIG. 10 illustrates the existing toilet device 3. The cleaning water supplied to the simple toilet device 10 is used by dividing the cleaning water supplied to the toilet main body 108 (4). The toilet main body 108 is improved so that filth (such as urine) from the simple toilet device 10 can be discharged directly into the toilet main body 108.

  A discharge pipe 110 is connected to the toilet body 108, and a discharge outlet 112 is provided on the upper side of the reservoir 109. A discharge pipe 113 is connected to the discharge outlet 112, and the discharge pipe 113 is connected to a connecting body 114 provided on the back side of the toilet body 108. The connector 304 of the discharge hose 14 (actually the common hose 300A) is connected to the connector 114. Instead of providing the discharge outlet 112, the discharge pipe 113 may be directly connected to the discharge unit 110 side.

  When the existing toilet main body 108 is improved in this way, there is a difference in height between the simple toilet device 10 and the toilet main body 108. When the connecting body 114 is located at a place higher than the toilet body 20 of the simple toilet device 10, there is a possibility that a waste of filth stays in the discharge hose 14. However, even when there is such a height difference, if the fluid is pressure-fed by the compressed air from the air compressor 200 described above, the fluid does not remain in the discharge hose 14, and the toilet body 108 side is surely provided. Can be discharged.

  The wall 260 of the existing toilet device 3 is provided with an operation unit 270 for hot water cleaning. In this example, a hook 280 is provided near the operation unit 270, and a response terminal device 290 can be attached thereto.

  The response terminal device 290 is sized to be portable, and in this example, in addition to the power switch 292 and the buzzer 293 as the notification means 310, in this example, a message that has received the use state signal is displayed. A display unit 294 as a notification lamp and an operation unit (operation switch) 296 for response are provided. Details will be described later.

  FIG. 11 shows an example of a control system of the simple toilet device 10. The control unit 50 performs control related to the use state of the simple toilet device 10 and the use of the simple toilet device 10. Therefore, the on / off signals of the power switch 52 and the open / close detection switch 55 described above are supplied to the control unit 50. The power switch 52 is a power switch when the simple toilet device 10 is used.

  Detection means for detecting the use state of the toilet device in relation to the toilet body 20 is provided. The use state may be detected at any timing before using the toilet (approaching for using the toilet), during use, or after use. In order to detect before using the toilet, the time of approaching the toilet is measured. This is to eliminate mere passage.

  The following example is an example of detecting that the toilet is being used, and the open / close detection switch 55 for the toilet lid 23 is also used as a detection means. The open / close detection switch 55 is a switch that is turned on / off in association with opening / closing of the toilet lid 23 for closing the upper part of the toilet seat 21, and is provided on the lower surface of the toilet lid 23 so as to face the toilet lid 23 as shown in FIG. 8. An open / close detection switch 55 is attached. Note that the toilet lid 23 is closed when the toilet is not in use.

  The drive state of the discharge solenoid valve 24, the water supply solenoid valve 32, the crushing motor 42, and the air compressor 200 described above is controlled by a control signal from the control unit 50 constituted by the CPU.

FIG. 12 shows an example of the control timing.
The simple toilet device 10 is used with the toilet lid 23 opened. The opening operation of the toilet lid 23 is detected by an open / close detection switch 55 (such as an open / close detection sensor switch) (FIGS. 12A and 12B). When the toilet lid 23 is open, defecation and urination are performed. After the toilet lid 23 is closed again, by operating the crushing switch 56 (see FIG. 8), the electromagnetic valve 32 for water supply is driven for a predetermined time Td to supply washing water (FIGS. 12C and E). ). This cleaning is for cleaning the filth adhering to the surface side of the lid main body 246, and is not intended for the filth to flow down from the reservoir 18, and the supplied cleaning water overflows from the reservoir 18. This is done with a relatively small amount of washing water that does not come out.

  Next, the motor 42 is driven, and pulverization processing of filth and the like is performed for a predetermined time Ta (FIG. 12D). The pulverization processing time Ta is selected to be a time during which filth and toilet paper can be sufficiently pulverized. As the time, for example, 20 seconds or less is selected.

  When the pulverization process is performed for a predetermined time Ta, the air compressor 200 is energized next, and compressed air is supplied into the accumulating portion 18, and the internal pressure by the compressed air is increased to a certain value (the air compressor 200). At a timing delayed by ΔTb), the discharge solenoid valve 24 is driven (FIGS. 12F and 12G).

  By doing so, a fluid discharge path is formed when the pressure in the reservoir 18 is increased to a certain value, so that the fluid in the reservoir 18 is pumped into the discharge hose 14. As a result, all of the flow material is discharged into the toilet body 108 through the discharge hose 14 without staying in the discharge hose 14.

  The fluid pressure-feeding time (discharge processing time) Tb differs depending on the installation length of the discharge hose 14, but in order to prevent the fluid from remaining in the discharge hose 14, it is relatively It can be set to a longer time, for example, about 10 to 30 seconds.

  When the pumping time Tb elapses, the discharge solenoid valve 24 is closed. At substantially the same time, the electromagnetic valve 32 for water supply is driven for a predetermined time Tc, and cleaning water is supplied again (FIGS. 12E and 12F). As a result, the cleaning water is trapped in the reservoir 18 and the initial state is restored.

  In order to carry the simple toilet device 10 or the like, although not shown, a discharge switch is provided, and the solenoid valve 24 can be opened by manual operation to discharge the trap water. The above-described opening / closing timing of the electromagnetic valve is merely an example. It can be changed as appropriate.

  The above-described opening / closing timing of the electromagnetic valve is merely an example. It can be changed as appropriate.

  The configuration of FIG. 11 will be described again. In addition to the above-described control of the simple toilet device 10 itself, the control unit 50 performs control related to detection of the toilet use state. Therefore, the control unit 50 is provided with a transmission / reception unit 264, and an antenna 266 is connected to the transmission / reception unit 264. The transmission / reception unit 264 functions as a transmission unit and a response reception unit. In addition, when the response signal is received, the notification unit 250 is activated by a control signal from the control unit 50. In this example, the notification means 250 is provided with a buzzer 252 and a display lamp 254 as a notification lamp for notification. Further, the indicator lamp 254 may be configured such that the lamp (LED or the like) itself is lit, but may be notified by displaying characters, figures, or the like.

  FIG. 13 shows a schematic system diagram of the other device that constructs the toilet system, that is, the response terminal device 290. The response terminal device 290 has a status signal receiver. In this example, the transmission / reception unit 320 having a transmission function is used, and when the use state signal is received by the antenna 298, the notification unit 310 is driven. In this example, a case in which the notification unit 310 is configured by the buzzer 293 and the display unit 294 as a notification lamp configured by an LCD or the like is shown. When the use state signal is received, the buzzer 293 is driven and a caregiver or the like is audibly informed that the simple toilet device 10 is in use. At the same time, in this example, a received message is displayed on the display unit 294 to visually notify that the simple toilet device is in use. The received message is a fixed message stored in the display unit 294, and for example, a message such as “busy in use” is displayed. Note that instead of the display portion 294, a lamp may be lit. In addition to these, a vibrator may be added to notify by vibration.

  The response terminal device 290 shown in FIG. 13 has a function of returning a response signal to the simple toilet device 10 in addition to these notification functions. Therefore, an operation unit (response button) 296 having a function capable of outputting a response operation signal in association with the transmission / reception unit 320 is provided, and configured to be able to communicate with the antenna 298.

  When the response terminal device 290 receives the use state signal transmitted from the simple toilet device side, the caregiver or the like operates the operation unit 296 to thereby respond to the use state signal with respect to the simple toilet device 10 side. Can be replied. On the side of the simple toilet device 10, as described above, the provided buzzer 252 is driven in conjunction with the reception of the response signal, and the indicator lamp 254 is blinked or lit. By the operation of the notification means 250, a user (a care receiver or the like) of the simple toilet device 10 can recognize that he / she can be surely transmitted to the caregiver or the like that he / she is using the toilet.

  Communication processing between the simple toilet device 10 and the response terminal device 290 will be described with reference to FIG. When the usage state of the simple toilet device 10 is automatically detected by the usage state detection means, a usage state signal is transmitted from the transmission / reception unit 264 (FIG. 12H). When the open / close detection switch 55 is used as the use state detection means, it is determined that the toilet is used by opening the toilet lid 23, and therefore a use state signal is transmitted in conjunction with the opening / closing timing.

  When the response terminal device 290 receives this use state signal, the buzzer 293 is driven (FIG. 12I, J), so that the caregiver can remotely recognize that the toilet is being used. By sounding the notification sound, even if the caregiver is in business, the caregiver can be surely recognized that the toilet is in use. Just go to your room. This can be confirmed by the display unit 294 simultaneously with the buzzer.

  By operating the response operation unit 296, the response buzzer 252 and the like are driven, so that the cared person can recognize that his message has been transmitted to the caregiver. Can do.

  On the other hand, by using the existing toilet device 3 by carrying the response terminal device 290, when using the existing toilet device 3 or trying to use the toilet device 3, a use state signal is received. In such a case, even if the use of the toilet device 3 is temporarily suspended or the toilet use is continued as it is, there is no particular sense of incongruity. This is because it can be expected that filth will be discharged from the simple toilet device 10.

  It is convenient to prepare a plurality of response terminal devices 290. One of them is installed in the existing toilet device 3. This is because it is possible to eliminate the inconvenience of having to carry the response terminal device 290 when using the existing toilet device 3.

  In the above description, the open / close detection switch 55 is exemplified as the toilet use state detection means. Various other switches can be used as the use state detection means. For example, the weight of the user can be detected by attaching a weight sensor separately from the open / close detection switch 55 to the lower surface side of the toilet seat 21 on the upper surface of the opening of the toilet body 20.

  When the cared person sits on the toilet seat 21, the weight is detected by the weight sensor via the toilet seat 21. If the detection threshold is set so that the weight sensor is turned on when the weight is several tens of kg or more, the sitting position of the cared person can be reliably detected without malfunction. And the use condition of the toilet can be detected by guiding the signal when the weight sensor is turned on to the control unit 50.

  In addition to this, various detection sensors and similar means can be used as the toilet usage state detection means. A typical example is shown below.

(1) Odor sensor An odor sensor is attached to the toilet body 2. The attachment location is arbitrary, but it is attached to the opening end of the toilet body 20 where the odor can be detected as easily as possible, for example, at the same location as the weight sensor. By doing so, the odor of filth can be sensed, so that the use state of the toilet can be sensed.

(2) Cleaning operation switch A cleaning operation switch (not shown but provided in the hot water cleaning operation section) used for cleaning the buttocks is used as a detection sensor. When the washing operation switch is operated, a toilet use state signal is transmitted. Note that actual pulverization and discharge processing is performed at the stage where the cleaning processing is completed.

(3) Human sensor By attaching the human sensor to the toilet body 20, the usage state of the simple toilet device 10 is detected. When passing through the vicinity of the simple toilet device 10, the human sensor is devised so as not to detect the approach of a person.

  FIG. 14 shows another example of a simple toilet device. In the example of FIG. 14, the opening / closing lid mechanism is configured to be a slide type. The description of the same components as those in FIG. 8 is omitted.

  The opening / closing lid mechanism 210 shown in FIG. 14 is arranged on the upper part of the pressure feeding means 200 with a small gap from the pressure feeding means 200. The opening / closing lid mechanism 210 includes a lid body 212 that seals the reservoir 18 and an opening / closing drive unit 213 that opens and closes the reservoir 18 by moving the lid body 212 back and forth.

  An electromagnetic solenoid 218 can be used as the opening / closing drive unit 213. The tip of the piston 216 that moves forward and backward in the electromagnetic solenoid 218 is attached to a coupling body 214 provided in a part of the lid main body 212.

  As shown in FIG. 15, an example of the lid main body 212 is a flat plate-like shape along the inner peripheral shape of the reservoir portion 18, and in this example, the lid main body 212 has a shape like a cocoon or a bowl. In this example, a plastic molded article coated with an antibacterial agent is used.

  In this example, the lid body 212 is integrally formed so that a part of the lid body 212 becomes the coupling body 214. The connection body 214 has a rectangular shape. The tip of the piston 216 described above is fitted and fixed to the opposite side of the connecting body 214 by press fitting or the like. The piston 216 is an operating rod having a column shape that moves forward and backward in the electromagnetic solenoid 218 by energizing the electromagnetic solenoid 218. In addition, similar opening / closing operations can be performed by a combination of an air cylinder and a gear.

  FIG. 14 shows a state in which a lid main body 212 as an open / close lid is closed, and the inside of the reservoir portion 18 is sealed by the lid main body 212. On the other hand, FIG. 16 shows a state in which the lid main body 212 is retracted and the reservoir 18 is opened.

  Such an advancing / retreating operation with respect to the lid body 212 is performed by energizing and releasing the electromagnetic solenoid 218, and the stroke thereof is the first switch 222 provided on the lid body 212 side of the electromagnetic solenoid 218 and the wall surface 18 a of the toilet body 20. It is detected by a second switch 224 provided on the side. The end of the stroke of the lid body 212 is detected by the contact of the coupling body 214 with the first and second switches 222 and 224.

  By the sliding contact with the upper surface of the reservoir 18 of the lid body 212, the interior of the reservoir 18 is sealed. A complete seal is not necessary. When the air compressor 200 is operated in this closed state, the compressed air is fed into the reservoir 18 and a pressing force acts on the trap water. By opening the electromagnetic valve 24 in this state, the pulverized material in the reservoir 18 is pumped to the discharge hose 14 side, so that the same discharge as described above is possible.
