JP 2004-308404 A

  By the way, when the simple toilet device disclosed in Patent Document 1 is a flush toilet device, the supply of the wash water and the treatment of excreted waste matter become problems. It is conceivable to use an existing toilet device as a means for solving this problem. That is, the toilet system is constructed such that the cleaning water of the existing toilet device is guided to the simple toilet device, and the filth (hereinafter referred to as filth) of the simple toilet device is discharged together with the used cleaning water to the toilet of the existing toilet device. If the existing toilet device can be used in this way, there is an advantage that facility costs, construction costs, etc. when using the simple toilet device can be suppressed.

  When constructing such a toilet system, when the filth of the simple toilet device is discharged to the existing toilet device side, the filth discharged to the existing toilet device side stays in the toilet of the existing toilet device as it is. Therefore, a family member, a caregiver or the like must go to the existing toilet device and manually operate the cleaning switch of the existing toilet device to discharge and clean the filth.

  Disposing of filth by bothering the hands of a family means that, for example, when there are no family members or caregivers, the filth discharged to the existing toilet device will stay as it is, and the generation of off-flavors or This can increase discomfort for those who use the existing toilet device.

  Therefore, the present invention solves such a conventional problem, and particularly in a toilet system constructed by a simple toilet device and an existing toilet device, the discharge processing is performed on the simple toilet device side. When this is detected, a toilet system is proposed in which filth stay is prevented by automatically performing cleaning / discharge processing on the side of the existing toilet device after the end of the discharge processing.

In order to solve the above-described problem, in the toilet system according to the present invention described in claim 1, in the toilet system configured to discharge the waste excreted in the simple toilet device into the toilet of the existing toilet device,
Filth discharge detection means for detecting discharge of filth from the simple toilet device to the existing toilet device;
A control unit for controlling the cleaning and discharging mechanism provided in the existing toilet device based on the discharge detection signal detected by the filth discharge detection means,
The cleaning and discharging mechanism is operated when the discharge detection signal is a signal indicating the end of the discharge of filth.

  In this invention, a toilet system is constructed by a simple toilet device and an existing toilet device. This toilet system includes a filth discharge detection means for detecting discharge of filth from a simple toilet apparatus to an existing toilet apparatus, and a cleaning provided in the existing toilet apparatus based on a discharge detection signal detected by the filth discharge detection means. A control unit for controlling the discharge mechanism. The waste discharge detection means and the control unit are provided in either the existing toilet device or the simple toilet device. Usually, it is provided on the existing toilet device side which is the controlled side.

  When the filth discharge detection means is provided on the existing toilet device side, the filth discharge detection means is provided on a part of the discharge pipe provided in connection with the connection portion of the discharge hose connected to the simple toilet device side. Installed. Instead of being connected to the discharge pipe, this waste discharge detecting means may be provided in the discharge hose connecting portion provided in the existing toilet apparatus. As the filth discharge detection means, a flow rate detection means (flowing water detection means), a pressure sensor (water pressure sensor), and the like can be considered.

  The start and end of the discharge process are detected by the filth discharge detection means. The cleaning and discharging mechanism provided in the existing toilet device is controlled by the discharging detection signal. When the toilet device with the butt cleaning device is used as the existing toilet device, the cleaning / discharging mechanism is controlled by a cleaning / discharging switch provided in the butt cleaning device. In this example, the cleaning and discharging mechanism is controlled by the control unit. Therefore, a signal equivalent to that obtained when the cleaning / discharging switch is operated is supplied from the control unit to the cleaning / discharging mechanism.

  The cleaning and discharging mechanism only needs to send a control signal indicating its start. As is well known, the cleaning and discharging process is automatically stopped when a predetermined time has elapsed from the start of cleaning and discharging.

  Toilet use restriction means is further provided on the existing toilet device side. The toilet use restriction means includes a display unit for displaying that the use of the existing toilet device is restricted, and a toilet lid opening / closing control means for controlling the opening / closing of the toilet lid of the existing toilet device.

  This is to eliminate the anxiety of a person who happens to use the existing toilet device when the simple toilet device is performing the discharge process and to limit the use of the toilet. By providing the display unit, the current control mode can be understood. During the discharge process, the use of the existing toilet device can be temporarily restricted by locking the toilet seat so that it does not open. As the toilet seat opening / closing control means, in addition to a simple locking mechanism, a closing / locking mechanism for locking after closing once can be used.

  For example, when the locking means for the toilet lid is used as the usage restricting means for the simple toilet, the locking means operates to restrict the opening and closing of the toilet lid. If you try to open the toilet lid, you cannot open it.

  The simple toilet device can take various configurations. For example, filth crushing means is provided in the toilet body of the simple toilet device. The crushed filth is pumped to the existing toilet device. In order to effectively pump and keep the inside of the toilet body clean, a configuration such as providing an open / close lid that closes the upper part of the reservoir is conceivable.

  In the toilet system according to the present invention, the discharge of filth and the like from the simple toilet device side is detected, and the filth discharge mechanism of the existing toilet device is automatically operated.

  According to this, when it is detected that the discharge process has been performed on the simple toilet device side, the cleaning / discharge process on the existing toilet device side can be automatically performed after the end of the discharge process. As a result, it is possible to prevent stagnation of filth, and to eliminate the generation of off-flavors and the anxiety of existing toilet device users.

  Next, a preferred embodiment of the toilet system according to the present invention will be described in detail with reference to the drawings.

  The toilet system according to the present invention is constructed by a portable simple toilet device devised so that it can be used in a living room and an existing toilet device. FIG. 1 shows an example. The simple toilet device and the existing toilet device are connected by a hose (wash water hose and discharge hose).

  FIG. 1 shows an example in which an existing toilet device 3 is installed facing the corridor 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.

  The simple toilet device 10 that can be used in the room 6 is preferably a simple toilet device (Western-style toilet type) equipped with a so-called hot water cleaning toilet seat with a butt cleaning function. The explanation of the equipment is omitted. The supply of cleaning water to the simple toilet device 10 is performed from the existing toilet device 3 side, and the filth and the like of the simple toilet device 10 are discharged into the toilet 4 of the existing toilet device 3. Therefore, the water supply hose 12 connected to the simple toilet device 10 is connected to a water supply pipe (not shown) of the existing toilet device 3. Similarly, the discharge hose 14 connected to the simple toilet device 10 is connected to a connecting portion (described later) provided in the toilet bowl 4.

  In this toilet system, a flow rate detection switch 280 provided on the side of the existing toilet device 3 as filth discharge detection means for detecting discharge of filth from the simple toilet device 10 to the existing toilet device 3, and the flow rate detection And a control unit 300 that controls a cleaning / discharging mechanism provided in the existing toilet device based on the discharge detection signal detected by the switch 280. The flow rate detection switch 280 and the control unit 300 are provided in either the existing toilet device 3 or the simple toilet device 10. The following example shows the case where it is provided on the existing toilet device 3 side that is the controlled side. The simple toilet device 10 will be described.

  FIG. 2 is a cross-sectional view of an essential part showing an example of a simple toilet device 10 applicable to the present invention. The toilet body 20 provided in 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. In recent years, interior elements are also desired, and not only a box shape but also a chair type with an armrest, for example, can 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, but may be formed using other materials such as ceramics. 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 portion 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 portion 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. These shapes can provide the same effects. In addition, the discharge part 22 having a substantially “H” cross section is generally called an “S” trap.

  The electromagnetic valve 24 functions as a part of the discharge mechanism together with the electromagnetic valve 32 for water supply. 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 control discharge and prevent water leakage. Further, at the same time, waste is effectively discharged by the pressure of the air compressor described later.

  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 portion 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 portion 34. This is because water supply (washing water) from the water supply hose 12 connected to the connection portion 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 18a so as not to leak into the back space 20a 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 composed of a motor 42 and crushing blades 44. In FIG. 2, 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 not to the bottom outer wall 19 side of the reservoir 18 but to the bottom plate 20 c of the toilet body 20.

  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. The 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. On the lower surface of the toilet lid 23, an open / close detection switch 55 (described later) for detecting opening / closing of the toilet lid 23 is provided. ing.

  On the upper surface of the toilet body 20, in this example, on the rear surface side of the toilet seat 21, a notification unit 250 controlled by the control unit 50 is installed. The notification means 250 is provided as necessary. This is to inform the control mode on the existing toilet device 3 side. In this example, the notifying means 250 is composed of a character display section and a notification indicator lamp. Details thereof will be described later.

  The simple toilet device 10 further has the following structure. As shown in FIG. 2, 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. The pressure feeding means 200 and the opening / closing lid mechanism 245 for sealing the reservoir 18 are 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. Similarly, in order to exhibit the same function as the pressure feeding means 200 for feeding the predetermined compressed air to the reservoir portion 18, it is possible to take in the compressed air from the outside of the main body of the simple toilet device and perform the same action. .

  The opening / closing lid mechanism 245 is further above the pressure-feeding means 200, but is arranged with a small clearance from the pressure-feeding means 200. As the opening / closing method of the opening / closing lid body, a slide type and a rotation type are conceivable. FIG. 2 shows an example of a rotation type.

  As shown in FIG. 2, a reduced diameter portion 240 is provided at the upper portion of the reservoir portion 18 and slightly above the attachment 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 has a shape along the lower surface edge 242, and normally, the rotation shaft portion 247 and the wall surface of the lower surface portion 241 can be sealed so as to be in contact with the lower surface edge 242 and seal the inside of the pool portion 18. An urging spring 248 is wound between them.

  When the simple toilet device 10 is configured in this manner, 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. 3), so the excrement falls into the pool portion 18. To do. When the excrement falls, the lid body 246 automatically returns to the original position (see FIG. 2) by the action of the spring 248 and the upper portion of the reservoir 18 is closed.

  2 and 3, an example in which the lid main body 246 is provided so as to be substantially horizontal in the original position is illustrated, but as described above, the reduced diameter portion 240 is provided to be slightly inclined toward the discharge portion 22 side. Therefore, if the lid body 246 itself constituting the opening / closing lid mechanism 245 is attached to be inclined toward the discharge portion 22 side, the excrement dropped on the upper surface of the lid body 246 is not left and dropped into the pool portion 18. be able to.

  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 required. 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 can be pumped to the discharge hose 14 side. Here, the pulverized material refers to a fluidized material obtained by mixing pulverized filth and trap water.

  Thus, since the reservoir 18 is sealed by the lid body 246, 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 together with the cleaning water if compressed air is applied to the pool portion 18.

  Since the fluid is pumped in a state where the inside of the reservoir portion 18 is sealed, the air compressor used as the pumping means 200 can use a relatively small compressor. 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. 4 illustrates the existing toilet device 3. The cleaning water supplied to the simple toilet device 10 is used by diverting the cleaning water supplied to the toilet body 108. 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.

  In the example of FIG. 4, 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 portion 114 provided on the back side of the toilet body 108. A connecting portion 62B of the discharge hose 14 is connected to the connecting portion 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 body 108 is improved in this way, there may be a difference in height between the simple toilet device 10 and the toilet body 108. When the connection part 114 is located in 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 existing toilet device 3 is provided with a flow rate detection switch 280 that detects discharge of filth from the simple toilet device 10 to the existing toilet device 3. The flow rate detection switch 280 is provided in a part of the discharge pipe 113. In this example, a flow rate detection switch 280 is configured as a filth discharge detection means for detecting the presence or absence of filth flowing through the discharge pipe 113. When an impeller or the like is used as the flow rate detection means, the impeller is attached so as to face the flow path of the discharge pipe 113.

  By providing the flow rate detection switch 280 in a part of the discharge pipe 113, when filth is discharged from the side of the simple toilet device 10, the flow material containing the filth passes through the discharge pipe 113 and enters the toilet body 108. Discharged. Since the impeller rotates or stops in association with this discharge processing, the start and end of waste discharge can be detected by the flow rate detection switch 280. A discharge detection signal from the flow rate detection switch 280 is supplied to the control unit 300 described later.

  Instead of the flow rate detection switch 280, a pressure sensor (water pressure sensor) may be used. This is because the flow in the discharge pipe 113 changes the pressure in the discharge pipe 113 so that the start and end of waste discharge can be detected by this pressure change. The flow rate detection switch 280 can also be incorporated inside the connecting portion 114.

  Locking means 268 is provided on the upper surface of the toilet body 108 in relation to the rotation shaft 230 a of the toilet lid 230. The lock means 268 functions as one of toilet use restricting means, and serves as a rotation restricting means for the rotation shaft 230a. As will be described later, when the discharge process for the simple toilet device 10 is detected, the locking means 268 is activated. When the locking means 268 is operated, the rotation shaft 230a is not moved and the toilet lid 230 is locked. When the discharging process of the existing toilet device 3 is completed, the toilet lid 230 is unlocked by the lock unit 268, and the existing toilet device 3 can be used.

  When the lock mechanism that can be used as the toilet use restricting means is a close / lock mechanism, an open / close detection switch 115 for detecting the open / closed state of the toilet lid 230 is provided as shown in FIG. When the opening / closing state of the toilet lid 230 is detected by the detection switch 115 and the closing / locking mechanism is activated, if the toilet lid 230 is open, the locking mechanism is operated after the toilet lid 230 is closed. The subsequent operation is the same as described above.

  An operation unit 270 for hot water cleaning is provided on the wall 260 of the existing toilet device 3. In this example, the control unit 300 related to the existing toilet device 3 is built in the case of the operation unit 270. In addition, a display unit that functions as a toilet use restriction unit is also incorporated. It can be seen that the use of the existing toilet device 3 is restricted by the contents of the display unit.

  In the control unit 300, the cleaning and discharging mechanism is controlled by the above-described discharging detection signal. Specifically, when the discharge detection signal is a signal indicating the end of discharge of filth, control for operating the cleaning / discharging mechanism is performed. That is, the same signal as when the discharge cleaning switch is operated is generated and supplied to the cleaning / discharging mechanism. As the cleaning and discharging mechanism, a control valve (electromagnetic valve) 302 (see FIG. 9) that controls the supply of cleaning water can be used.

  The operation unit 270 is provided with a cleaning / discharging switch 272 and its stop switch 274. On the operation panel side of the operation unit 270, the above-described character display unit 295 that functions as toilet use restriction means is further provided. In this example, a buzzer 293 and an indicator lamp 296 are additionally provided. In the character display unit 295, a message such as “in use of toilet” or “in discharge process” indicating that the simple toilet device 10 is being discharged is displayed to notify a person who uses the existing toilet device 3. . At the same time, the buzzer and the lighting process can be performed for more reliable notification.

  An example of the water supply hose 12 connected between the simple toilet device 10 configured as described above and the existing toilet device 3 is shown in FIG. 5, and an example of the discharge hose 14 is shown in FIG. As shown in FIG. 5, when one end 12a of the water supply hose 12 is an end connected to the water supply pipe side and the other end 12b is an end connected to the simple toilet device 10, one end 12a and the other Connecting portions 60A and 60B with check valves are attached to the end portion 12b.

  Similarly, the discharge hose 14 shown in FIG. 6 is provided with connecting portions 62A and 62B with check valves at one end portion 14a and the other end portion 14b. In this case, one end portion 14a is an end portion connected to the simple toilet device 10 side, and the other end portion 14b is an end portion connected to the sewer pipe side or the like.

  Since the water supply hose 12 is used for the washing water supplied to the toilet body 20, a small-diameter vinyl hose or the like can be used. On the other hand, since the discharge hose 14 is a material in which a flow material (granular material) obtained by pulverizing filth flows in the pipe, a vinyl hose having the same diameter as the water supply hose 12 or a slightly thicker diameter is used. be able to. This is not for solidified waste, but for handling fluids mixed with wash water. FIG. 6 shows a case where a discharge hose 14 having a diameter larger than that of the water supply hose 12 is used.

  For example, if the pipe diameters of the water supply hose 12 and the discharge hose 14 are selected as described above, the water hose 12 is used as a discharge hose because the thickness is originally different, or the discharge hose 14 is mistaken for the water supply hose. It is possible to reliably prevent rudimentary misconnection work. Of course, not only when using pipes with different pipe diameters, but also when using pipes with the same pipe diameter, as shown in FIGS. 5 and 6, names used as marks, such as “water supply hose” and “discharge hose”, are used. By imprinting the name on the surface of the hose, erroneous connection can be reliably prevented. Moreover, misconnection prevention can also be performed by making the joining bracket shape of a connection part non-common. Furthermore, it is possible to prevent erroneous connection by changing the colors of the water supply hose and the discharge hose.

  An example of the connection part 60 (62) with a check valve is shown in FIG. As shown in FIG. 7, a valve working chamber 64 having a rectangular cross section is provided in the hollow inside of the main body 63, and a sphere 65 that acts as a valve and a pressing spring 66 for the sphere 65 are provided therein, and water pressure acts in the direction of arrow a. This opens the valve. This prevents backflow from both the simple toilet device side and the water and sewage pipe side.

  On the other hand, in the other connecting portion 60B (62B) of the connecting portions 60 (62), when this is connected to the simple toilet device side and the sewer pipe side of the existing toilet, for example, the check valve sphere 65 is Protruding parts (not shown) that retreat against the pressing spring 66 are provided on the simple toilet device side and the sewer pipe side, respectively, so that when the connecting part 60 (62) is connected, the internal valve is opened. When the connection is established and the connection is removed, the internal valve is closed, and the liquid in the hose is configured not to leak to the outside.

  Therefore, with the connecting part 60A of the water supply hose 12 attached to the water supply pipe and the connecting part 60B attached to the toilet body 20 side, the water inside the pipe does not flow out even if the connecting part 60A is removed, and the other connecting part 60B is connected. Even if it is removed, the water inside the tube will not flow out. Similarly, even if the discharge hose 14 in use is removed, the sewage inside the pipe does not flow out to the outside.

  FIG. 8 shows an example of a control system related to the simple toilet device 10. The control unit 50 mainly controls the simple toilet device 10 itself. The controller 50 is supplied with an on / off signal from a power switch 52, an open / close detection switch 55, and a crushing switch (also a discharge switch) 56. Here, the crushing switch 56 is a manual switch that is used when the motor 42 is driven to crush the filth and the like in the reservoir 18, and the discharge process is also performed in conjunction with this. Although the crushing switch 56 is not shown in FIG. 2, the crushing switch 56 can be provided on the rear side of the upper surface of the toilet body 20 and at a location where it can be easily operated.

  Each drive state of the discharge electromagnetic valve 24 constituting the discharge mechanism, the water supply electromagnetic valve 32, the crushing motor 42, and the air compressor 200 constituting the discharge mechanism is controlled by a control signal from the control unit 50 constituted by the CPU. Be controlled.

  When the waste disposal process is being performed, the information is also supplied to the notification unit 250. The notification means 250 includes a notification display lamp 254 such as an LED and a character display unit 256 such as an LCD. A buzzer 252 may be used in combination. The notification means 250 allows the simple toilet user to recognize that the processing of the existing toilet device 3 is restricted by the use of the simple toilet device 10.

  FIG. 9 shows a schematic system diagram of the control device 300 on the existing toilet device 3 side. In addition to the detection signal from the open / close detection switch 115 for the toilet lid 230, the control unit 300 constituted by the CPU is also supplied with each of the cleaning switch 272, the cleaning stop switch 274, and the flow rate detection switch 280 shown in FIG. A signal is supplied. In response to the cleaning signal and the cleaning stop signal, the control unit 300 controls the control valve (electromagnetic valve) 302 for cleaning water. The control valve 302 constitutes a discharge mechanism of the existing toilet apparatus 3 as described above.

  When the discharge detection signal is obtained from the flow rate detection switch 280, the notification means 310 for displaying that the use of the toilet is restricted according to the state and the cleaning water control valve 302 as the discharge mechanism are activated. Then, the lock unit 304 operates. First, the notification unit 310 is configured by a buzzer 293, a display unit 295 such as an LCD, and an indicator lamp 296 such as an LED, and notifies the audiovisually that the simple toilet device 10 is in the discharge processing state. Thus, the usage status of the simple toilet device 10 can be recognized.

  When the discharge detection signal is a signal indicating the end of the discharge process, the cleaning water control valve 302 is controlled to be opened after a predetermined time has elapsed since the signal was obtained, and the discharge / cleaning process is automatically performed. Is executed automatically. Thus, the fluid accumulated in the toilet main body 108 can be discharged.

  The reason why the discharge / cleaning process is performed after a predetermined time has elapsed after the discharge detection signal is supplied is to allow the flow material sent into the toilet body 108 to be discharged when the discharge process is completely completed. It is to make it.

  When the discharge process from the simple toilet device 10 side is being performed, it is preferable to restrict the use of the existing toilet device 3 side. Therefore, when the discharge detection signal is obtained, the lock unit 304 operates to restrict the opening and closing of the toilet lid 230, and the toilet lid 230 is locked. The lock of the toilet lid 230 is released after a predetermined time has elapsed since the discharge process of the existing toilet device 3 is completed.

Next, the operation of the control system configured as described above will be described with reference to FIGS. 10 and 11. FIG. 10 shows an example of control timing on the simple toilet device 10 side.
When the simple toilet device 10 is not used, the toilet lid 23 is in a closed state. The simple toilet device 10 is used with the toilet lid 23 opened. The opening operation of the toilet lid 23 is detected by the open / close detection switch 55 (FIGS. 10A and 10B), and defecation and urination are performed when the toilet lid 23 is open. After the toilet lid 23 is closed again, by operating the crushing switch 56, the water supply electromagnetic valve 32 is driven for a predetermined time Td to supply wash water (FIG. 10E). This cleaning is for cleaning the filth adhering to the surface side of the lid main body 246, and is not intended to allow 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 is performed for a predetermined time Ta (FIG. 10D). 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. 10G and 10F).

  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 water supply electromagnetic valve 32 is driven for a predetermined time Tc, and the cleaning water is supplied again (FIGS. 10E and 10F). 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.

FIG. 11 shows a regulation example of the discharge process in the existing toilet device 3.
When the fluid is discharged from the simple toilet device 10 side, the discharge initial (start) state is detected by the flow rate detection switch 280. The buzzer 293 is driven by the discharge detection signal (ON signal) at that time to notify that the discharge to the toilet body 108 is performed (FIGS. 11A and 11B).

  At the same time, the display unit 295 and the indicator lamp 296 are simultaneously operated to indicate that the discharge process is being performed, and the indicator lamp 296 is lit (or flashed) (FIG. 11C). This notification process is to make the user of the existing toilet device 3 recognize that the simple toilet device 10 is in use.

  When the discharge of the fluid is completed, a discharge detection signal (off signal) associated therewith is obtained (FIG. 11A). When the discharge detection signal is obtained and the time tb after the predetermined time Tx has elapsed from the time ta when the discharge detection signal is obtained, the discharge / cleaning process is performed for the first time (FIG. 11D). By this discharge / cleaning process, the fluid from the simple toilet device 10 side is automatically discharged from the toilet body 108 without staying in the toilet body 108. The discharge / cleaning process of the existing toilet device 3 is performed for a preset time, and then automatically stops.

  Here, even if it is a signal indicating that the discharge process has ended, it is possible that the flow material is still flowing into the toilet body 108 immediately after that, so the discharge process of the existing toilet device 3 is performed. Should be done when the flow is definitely finished. From such a viewpoint, the delay time Tx is set. Therefore, this delay time Tx is about 5 to 10 seconds.

  When a discharge detection signal that detects the start of the discharge process is obtained, the locking means 304 of the toilet lid 230 is activated (FIG. 11E). This restricts the use state of the existing toilet device 3. The locked state is until the discharge / cleaning process ends (time tc). In this way, the use of the existing toilet device 3 is not performed until the discharge of the filth flowing into the existing toilet device 3 is completed (during time Ty) after the filth flow starts from the side of the simple toilet device 10. This is to limit the user of the existing toilet device 3 so as not to feel uncomfortable.

  In the embodiment described above, the flow rate detection switch 280 is installed on the existing toilet device 3 side, but it can also be installed on the simple toilet device 10 side. In this case, for example, the opening / closing detection switch 55 of the toilet lid 23 can be used as the flow rate detection switch 280. This is because by opening the toilet lid 23, the intention to use the simple toilet device 10 can be understood, and by closing the toilet lid 23, it can be determined that the use of the simple toilet device 10 has been completed (see FIG. 10H). However, in this case, since the discharge process of the simple toilet device 10 is indirectly detected, it is assumed that the discharge process is executed a predetermined time after the open / close detection switch 55 is turned on. After a predetermined time has elapsed after the discharge process, the existing toilet apparatus 3 side is discharged.

  As the flow rate detection switch 280, the crushing switch 56 can also be used. In this case, since the discharge / cleaning process is performed after the pulverization process, the discharge process of the filth is detected with almost no time lag although it is an indirect detection. In addition to these, a control signal for controlling the electromagnetic valve 24 to be in an open state can be used as a discharge detection signal, and even if the flow rate detection switch 280 is attached to the connecting portion 62A side of the discharge hose 14, Discharge processing can be detected.

  The discharge detection signals from the respective flow rate detection switches 280 are transmitted to the control unit 300 provided on the existing toilet device 3 side by wireless or wired. In the case of a wired connection, a signal line can be used, and a power line can also be used. In the case of a power line, the discharge detection signal is transmitted using power line carrier communication.

  FIG. 12 shows another example of the simple toilet device 10. FIG. 12 particularly shows a case where a slide-type opening / closing lid mechanism 210 is used. In this example, an opening / closing drive unit 213 is provided. When the electromagnetic solenoid 218 is used as the opening / closing drive unit 213 as shown in FIG. 12, the tip of the piston 216 that moves forward and backward in the electromagnetic solenoid 218 is attached to the connecting portion 214. The connecting part 214 forms a part of the lid main body 212. The electromagnetic solenoid 218 is attached and fixed by a holding part 220 protruding to the back side of the main body.

  As shown in FIG. 13, an example of the lid 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, both are integrally formed so that a part of the lid main body 212 becomes the connecting portion 214. The connecting part 214 has a rectangular shape. A water leakage prevention member 230 is interposed on the inner surface where the lid body 212 advances and retreats.

  The tip of the piston 216 described above is fitted and fixed to the opposite side of the connecting portion 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, a similar opening / closing operation can be performed by a combination of an air cylinder and a gear.

  FIG. 12 shows a state in which the lid main body 212 as an open / close lid is closed, and the inside of the reservoir 18 is sealed by the lid main body 212. On the other hand, FIG. 14 shows a state in which the lid body 212 is retracted and the reservoir 18 is opened.

  Such a forward / backward movement with respect to the lid body 212 is performed by energizing and releasing the electromagnetic solenoid 218. As shown in FIG. 12, the stroke is the first switch 222 provided on the lid body 212 side of the electromagnetic solenoid 218, and the toilet bowl. It is detected by a second switch 224 provided on the wall surface 18a side of the main body 20. The end of the stroke of the lid main body 212 is detected by the contact of the connecting portion 214 with the first and second switches 222 and 224.

  The switch for operating the lid body 212 may be manually operated or interlocked with the toilet lid 23 or the like. When the operation switch is operated, the lid main body 212 is closed, and the crushing processing and discharging processing of the filth are started. Even if the simple toilet device 10 configured in this way is used, the same effects as described above can be obtained.

  The present invention can be used as a care support system such as a care facility or home care.
