Description

  The present invention relates to a toilet system including a simple toilet device and an existing toilet device. Specifically, when constructing a toilet system that can discharge the waste excreted in the simple toilet device into the toilet of the existing toilet device, each toilet device has a waste discharge mechanism and a control means for controlling the discharge. By providing, depending on the use state of the other party's toilet device, their own filth discharge mechanism is prohibited, and simultaneous use of both can be avoided.

  Portable elderly toilets have been developed for elderly people who need nursing care and for those who are physically disabled and difficult to visit existing toilets in their homes (for example, Patent Document 1).

  This portable toilet 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. The portable simple toilet is provided with a water supply hose for flowing cleaning water into the toilet bowl, a discharge hose for discharging filth, and means for pumping the filth.

JP 2004-308404 A

  By the way, when it is a flush toilet apparatus as a simple toilet apparatus disclosed by this patent document 1, the supply of the wash water and the processing of the excreted waste matter will be a problem. 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 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 the equipment cost when using the simple toilet device can be suppressed.

  However, since the existing toilet device is also used by family members, the simple toilet device may be used while the existing toilet device is used, or the existing toilet device is used while the simple toilet device is used. There are also cases. In such a case, for example, if filth and the like are suddenly discharged from the side of the simple toilet device while using the existing toilet device, the family using the existing toilet device cannot hide the confusion with surprise.

  Or, while using the simple toilet device, the existing toilet device side is cleaned to discharge filth, so that the washing water is not sufficiently stored in the tank on the existing toilet device side. In some situations, filth may not be completely discharged. For this reason, if possible, it is preferable to avoid simultaneous use of the simple toilet device and the existing toilet device, but the problem described above can be solved by changing the discharge timing of filth even in simultaneous use. In other words, it is only necessary that the sewage is not discharged almost simultaneously between the simple toilet device and the existing toilet device.

  Therefore, the present invention has solved such a conventional problem, particularly in a toilet system constructed with a simple toilet device and an existing toilet device, so that simultaneous use of these toilet devices can be avoided, The present invention proposes a toilet system that can control its filth discharge mechanism according to the use state of the other party's toilet device.

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,
Each of the simple toilet device and the existing toilet device has a control unit that controls the filth discharge mechanism,
Communication means for performing communication between the simple toilet device and the existing toilet device is provided,
The control unit is configured to control its own filth discharge mechanism based on the received use state of the counterpart toilet device.

  In this invention, a toilet system is constructed using a simple toilet device and an existing toilet device. Each toilet device is provided with detection means for detecting the use state of the toilet device, and a waste discharging mechanism and a control unit having a communication function and a notification function are provided to control the discharging mechanism.

  The use state of each toilet device is detected, and when the use state is detected, a use state signal is transmitted to the other toilet device. As detection means for detecting the use state of the toilet device, an odor sensor, a weight sensor, a human sensor, a toilet seat open / close detection sensor, and the like are conceivable.

  When the other toilet device on the other side receives the use state signal of one toilet device, the waste discharging mechanism and the notification means are activated. When the other party's toilet device is being used, the discharge processing of the filth discharge mechanism is prohibited. When a signal indicating that the use of the other party's toilet device has been received is received, the prohibition of the discharge process is canceled, and the discharge process that was in standby is executed. By carrying out like this, it can avoid that each of two toilet devices discharges simultaneously.

  By operating the notification means, information to that effect is notified to the toilet device user, so that the reason why the discharge process is not executed can be immediately grasped even if the discharge operation is performed. As a result, the anxiety of the toilet device user can be eliminated.

  The notifying means is configured by any one or a combination of two or more of a display unit that displays the usage state as characters, an alarm means such as a buzzer, and an indicator lamp for notification.

  In addition to providing the control system of the discharge mechanism and its notification system in each of the simple toilet device and the existing toilet device, it is also possible to prepare a portable terminal device. By providing the portable terminal device with a communication means and a notification means that can communicate with the toilet device, the portable terminal device can grasp the use status of the toilet device and control the discharge thereof.

  The simple toilet device connected to the existing toilet device is not limited to one. It is possible to use several simple toilet devices. In this case, it is convenient to allow the control system of the existing toilet device to function as a master unit, and the control systems installed in a plurality of simple toilet devices to function as slave units. That is, the discharge function of all the simple toilet devices is controlled from the existing toilet device. Then, when the existing toilet device is in use, all discharge processing of the simple toilet device is prohibited. And, for example, when the first existing toilet device is in use, control is performed so as to prohibit the discharge processing in the second and subsequent existing toilet devices. By doing so, simultaneous use of a plurality of simple toilet devices and existing toilet devices can be avoided.

  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.

  The toilet system according to the present invention is provided with detection means for detecting the use state of both the simple toilet device and the existing toilet device, and also has a communication function and a notification for controlling the discharge mechanism of the filth and the discharge mechanism. A control unit having a function is provided.

  According to this, when one toilet device is in use, the other toilet device is notified of the use state, and discharge processing of the other toilet device can be prohibited. Simultaneous use with can be avoided. Therefore, it has an actual benefit that can eliminate discomfort of the toilet user.

  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.

  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 simple toilet device 10 has a toilet body 20. The toilet body 20 has a funnel-like cross-sectional shape that is substantially the same as that of a normal flush toilet (Western toilet), but the 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.

  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 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, when it transmits a signal indicating the use state or receives a state signal from the existing toilet device 3 (described later) A function for performing a corresponding process such as a discharge prohibition process is added.

  A power switch 52 for the control unit 50 is provided on the main body back surface part 20b, and is an upper surface part of the main body. On the lower surface of the toilet lid 23, an open / close switch 55 (described later) for detecting opening / closing of the toilet seat 21 is provided. . The open / close switch 55 also functions as a sensor that detects the use state of the existing toilet device 3.

  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. In this example, the notifying means 250 is composed of a character display section, a buzzer, and an indicator lamp for notification. 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 an opening / closing lid mechanism 210 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 210 is further above the pressure feeding means 200, but is arranged with a slight clearance 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.

  As a method of opening and closing the lid body 212, a slide type and a rotary type that rotates up and down by 90 ° or more are conceivable, and the configuration of the open / close drive unit 213 differs depending on whether it is a slide type or a rotary type.

  FIG. 2 shows a case where the slide type is used. In this example, when the electromagnetic solenoid 218 is used as the opening / closing drive unit 213, the tip of the piston 216 that advances and retreats in the electromagnetic solenoid 218 is attached to the connecting unit 214. The connecting part 214 forms part of the lid body 212 described above. 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. 3, 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. 2 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. 4 shows a state in which the lid main body 212 is retracted and the reservoir 18 is opened.

  Such a forward / backward movement with respect to the lid main body 212 is performed by energizing and releasing the electromagnetic solenoid 218. As shown in FIG. 2, the stroke is the first switch 222 provided on the lid main 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.

  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. 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 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 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, a relatively small compressor can be used as the air compressor used as the pumping means 200. Since the opening / closing lid mechanism 210 is used, when the filth is pulverized, it is possible to prevent the filth from scattering into the toilet body 20, so that the toilet body 20 does not become unsanitary.

  FIG. 5 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 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.

  Thus, when improving the existing toilet main body 108, a difference in height occurs between the simple toilet device 10 and the toilet main 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.

  An opening / closing detection switch 115 for detecting the opening / closing state of the toilet lid 230 is provided on the opening end side of the toilet body 108. The use state of the existing toilet device 3 is detected by the detection switch 115. In this example, when the toilet lid 230 is opened, it is determined that it is in use (in use), and when the toilet lid 230 is closed, it is determined that the use state has ended (used).

  An operation unit 270 for hot water cleaning is provided on the wall 260 of the existing toilet device 3. In this example, a hook 280 is provided near the operation unit 270, and a control unit for the existing toilet device 3, in this example, a portable control device 290 is attached thereto. The control device 290 has a transmission / reception function for communicating with the simple toilet device 10 and a notification function for notifying the use state of the simple toilet device 10 (details will be described later).

  In addition to the power switch 292, a notification unit 310 is disposed on the operation panel side of the control device 290. In this example, the buzzer 293, the character display unit 294, and the indicator lamp 296 constitute the notification unit 310. The character display unit 294 displays a message that has received the use state signal.

  An example of the water supply hose 12 connected between the above-described simple toilet device 10 and the existing toilet device 3 is shown in FIG. 6, and an example of the discharge hose 14 is shown in FIG. As shown in FIG. 6, 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. 7 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. 7 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 pipes with different pipe diameters are used, but also when pipes with the same pipe diameter are used, as shown in FIG. 6 and FIG. 7, names used as marks, such as “water supply hose” and “discharge hose” 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 connecting portion 60 (62) with a check valve is shown in FIG. As shown in FIG. 8, 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 having a valve action and a pressing spring 66 for the valve action 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 recede 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. 9 shows an example of a control system related to 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, in addition to the power switch 52 described above, an open / close switch 55 and first and second switches 222 and 224 are provided, and their on / off signals are supplied to the controller 50. The first and second switches 222 and 224 are switches that are turned on / off by the stroke of the lid body 212. 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 switch 55 for the toilet lid 23 is also used as a detection means. The open / close switch 55 is a switch that is turned on / off in connection with opening / closing of the toilet lid 23 for closing the upper portion of the toilet seat 21. In this example, the open / close switch 55 is opposed to the toilet lid 23 as shown in FIG. An open / close switch 55 is attached to the lower surface. Note that the toilet lid 23 is closed when the toilet is not in use.

  The drive states of the discharge solenoid valve 24, the water supply solenoid valve 32, the crushing motor 42, the air compressor 200, and the electromagnetic solenoid 218 described above are controlled by control signals from the control unit 50 constituted by the CPU. Here, the discharge solenoid valve 24 and the water supply solenoid valve 32 function as a part of the discharge mechanism.

  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 that functions as a communication means, and an antenna 266 is connected to the transmission / reception unit 264. In addition, when the use state signal is received, the notification unit 250 is activated by a control signal from the control unit 50. In this example, the notification unit 250 includes a buzzer 252, a notification display lamp 254 such as an LED, and a character display unit 256 such as an LCD. In addition to these, a vibrator may be added to notify by vibration.

  In response to the cleaning signal and the cleaning stop signal, the controller 50 controls the discharge solenoid valve 24. When the open / close detection signal is obtained, a corresponding state signal is transmitted from the transmission / reception unit 264 via the antenna 266. When the toilet lid 23 is opened, a status signal indicating that it is in use is generated and output. When the toilet lid 23 is closed, a status signal indicating that it has been used is generated and output.

  When the transmission / reception unit 264 receives a status signal from the existing toilet device 3, the control unit 50 determines the contents of the status signal and appropriately controls the electromagnetic valves 24 and 32 and the notification means 250.

  When it is determined that the received status signal is a signal indicating that the existing toilet device 3 is in use, both the solenoid valve 24 and the solenoid valve 32 serving as a discharge mechanism are controlled to be in the “closed state” and discharged (washed) Both processing and discharge processing are prohibited. At the same time, a corresponding control signal is also supplied to the notification means 250, and the buzzer 252 is driven for a predetermined time. At the same time, the indicator lamp 254 is turned on (or flashes), and a character “in use” is displayed on the display unit 256, for example.

  By operating the notifying means 250, information to that effect is notified to the toilet device user, so that the reason why the discharging process is not executed can be immediately grasped even if the discharging operation is performed. As a result, the anxiety of the toilet device user can be eliminated.

  When it is determined that the received status signal is a signal indicating the end of use of the existing toilet device 3, the use prohibition of the solenoid valves 24 and 32 is released, and when the discharge process is waiting, a predetermined time After that, the discharge process is executed. And the indicator lamp 254 in the alerting | reporting means 250 turns off, and the character of the display part 256 also disappears.

  FIG. 10 shows a schematic system diagram of the control device 290 on the existing toilet device 3 side. This control device 290 also has a control unit 300 constituted by a CPU, is supplied with a detection signal from the open / close detection switch 115 for the toilet lid 230, and each of the cleaning switch 272 and the cleaning stop switch 274 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 device 3. When the open / close detection signal is obtained, a corresponding state signal is transmitted from the transmission / reception unit 304 via the antenna 306. When the toilet lid 230 is opened, a status signal indicating that it is in use is generated and output. When the toilet lid 230 is closed, a status signal indicating that it has been used is generated and output.

  When the transmission / reception unit 304 receives a status signal from the simple toilet device 10, the control unit 300 determines the contents of the status signal and appropriately controls the control valve 302 and the notification unit 310 (see FIG. 5).

  When it is determined that the received state signal is a signal indicating that the simple toilet device 10 is being used, the electromagnetic valve 302 serving as the discharge mechanism is controlled to be in the “closed state”. At the same time, a corresponding control signal is supplied to the notification means 310, and the buzzer 293 is driven for a predetermined time. At the same time, the indicator lamp 296 is turned on (or flashes), and the display section 294 displays, for example, a character “in use”.

  When it is determined that the received status signal is a signal indicating the end of use of the simple toilet device 10, the use prohibition of the solenoid valve 302 is canceled, and when the discharge process is waiting, a predetermined time is allowed. Then, the discharge process is executed. And the indicator lamp 296 in the alerting | reporting means 310 turns off, and the character of the display part 294 also disappears.

FIG. 11 shows an example of control timing on the simple toilet device 10 side.
When the simple toilet device 10 is not used, the lid body 212 that is an open / close lid 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 an open / close switch 55 (open / close detection sensor switch or the like) (FIGS. 11A and 11B). When the toilet lid 23 is opened, the lid body 212 is opened by energizing the electromagnetic solenoid 218 (FIG. 11C). The stroke Tx of the lid body 212 is detected by the first switch 222, and when the first switch 222 is turned on, the energization of the electromagnetic solenoid 218 is released (FIG. 11D).

  When the lid main body 212 is opened, the toilet can be used, defecation and urination are completed, and when the toilet lid 23 is closed, the open / close switch 55 detects this and closes the lid main body 212. Alternatively, the lid body 212 is closed by transmitting the end of defecation and urination to the control unit 50 by an electrical signal from a manual switch. The stroke Tx in the closing direction of the lid body 212 is detected by the second switch 224 (FIG. 11E).

  When the lid body 212 is closed and the inside of the reservoir 18 is sealed, the crushing motor 42 is driven and the crushing process in the reservoir 18 is started (FIG. 11F). 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 accumulation portion 18, and the discharge electromagnetic wave is slightly delayed (ΔTb) from the energization of the air compressor 200. The valve 24 is opened to form a discharge path (FIGS. 11H and I). Thus, by slightly delaying the energization of the electromagnetic valve 24 from the energization of the air compressor 200, the pressure in the reservoir 18 can be increased. If the electromagnetic valve 24 is opened with the pressure in the reservoir 18 increased, the fluid in the reservoir 18 is pumped to the discharge hose 14 side by the supply of compressed air and the supply of cleaning water. The pressure feeding process is performed over a predetermined time Tb.

  The predetermined time Tb differs depending on the installation length of the discharge hose 14, but in order to prevent the flow material from remaining in the discharge hose 14, it is a relatively long time, for example, 10 to 30. It can be set to about seconds.

  When the predetermined time Tb has elapsed, the lid body 212 is now opened (FIG. 11C). When this opening operation is performed and the opening position of the lid body 212 is detected by the first switch 222, the upper portion of the reservoir 18 is opened. After the upper part of the reservoir 18 is opened, the water supply electromagnetic valve 32 is operated to inject water into the reservoir 18 for a predetermined time Tc (FIG. 11G). The predetermined time Tc is set to a water injection time during which the trap water in the reservoir 18 becomes a predetermined amount. Here, the predetermined amount refers to the amount of water stored until the water level of the trap water exceeds the bent portion of the discharge portion 22.

  When the water injection into the reservoir 18 is completed, the lid body 212 is closed and returns to the initial state (FIGS. 11C and 11D). The operation timing of each unit as described above is controlled based on on / off signals from a plurality of switches and the time set in software in the control unit 50. Moreover, it can also be cleaned more cleanly by repeating water supply and discharge.

  By setting to such an operation timing, it is possible to realize everything from crushing of filth to discharge processing and trap water trap processing. 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. 12 shows a discharge processing example on the simple toilet device 10 side. As described above, when the content of the status signal from the existing toilet device 3 is a signal indicating “in use”, a display such as “in use of toilet” is displayed (FIGS. 12A and 12B). At the same time, a discharge prohibition process is performed (FIG. 12C).

  When it is determined that the content of the status signal received at the next timing is a signal indicating “used (finished)”, a display such as “used” or “toilet is finished” is made (FIG. 12A). ). The discharge prohibition process is canceled at the timing tb after the elapse of the predetermined time Tw from the timing ta at which the state signal indicating the use is received (FIG. 12D). Therefore, when the discharge process is waiting, the discharge process is automatically performed after a predetermined time Tw has elapsed. The reason why the discharging process is executed after being delayed by the predetermined time Tw is because the person who used the existing toilet device 3 feels uncomfortable if the filth flows into the toilet 108 (4) before leaving the toilet. It is.

  At the stage when the discharge process is completed, a cleaning instruction signal (not shown) is sent from the simple toilet device 10 side to the existing toilet device 3 side. The existing toilet apparatus 3 automatically receives the cleaning instruction signal and performs the discharge process (cleaning process). This can prevent filth from staying in the toilet body 108.

  In the above-described first embodiment, the open / close switch 55 is exemplified as the toilet use state detecting means. Various other switches can be used as the use state detection means. If it demonstrates using the simple toilet apparatus 10, the weight sensor 56 as a detection sensor will be attached to the opening upper-surface part of the toilet seat 21 separately from the opening / closing switch 55 in the example of FIG. Therefore, the weight sensor 56 is attached between the toilet seat 21 and the toilet body 20.

  When the cared person sits on the toilet seat 21, the weight is detected by the weight sensor 56 via the toilet seat 21. If the detection threshold is set so that the weight sensor 56 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 detection sensor 56 is turned on to the control unit 50. Since other configurations and operations thereof are the same as those in the first embodiment, the description thereof is omitted.

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 20. 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) Operation switch for opening / closing lid An operation switch for operating the opening / closing lid 212 shown in FIG. 2 is used as a detection sensor. By operating this operation switch, the open / close lid 212 is closed, and the crushing processing and discharging processing of filth are started. Therefore, the control unit 50 is configured to transmit a signal indicating the use state of the toilet in association with the operation switch. In this case, the waste discharging process may be the same as in FIG.
(4) Human sensor By attaching the human sensor to the toilet body 20, the use 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.

These detection means can also be used as a detection means for a toilet use state in the existing toilet device 3.
(5) Weight sensor The reservoir 18 shown in FIG. 1 is provided separately from other parts of the toilet body 20, and a weight capable of measuring the weight of the reservoir 18 on a member that supports the reservoir 18 provided as a separate body. A sensor may be provided, and the weight of the reservoir 18 may be measured to determine the presence or absence of filth and detect the use state of the toilet.

  FIG. 14 shows another example of a simple toilet device. In the embodiment shown in FIG. 2, the opening / closing lid mechanism 210 is configured to be slidable. The example of FIG. 14 is a rotating type. In the following, description will be given of the rotary opening / closing lid mechanism 245, and the description of the same components as in FIG. 2 will be omitted.

  As shown in FIG. 14, for the pulverized material for feeding predetermined compressed air to the reservoir 18 at a predetermined position above the reservoir 18 in the toilet body 20 and below the water supply port 28. A pressure feeding means 200 is provided. A reduced diameter portion 240 is provided above the pool 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 pressure feeding means 200 is as described above.

  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 body 246 is urged so that the peripheral surface thereof is in contact with the lower surface edge 242 of the reduced diameter portion 240. 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 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. 15), so the excrement falls into the pool portion 18. To do. When the excrement falls, the lid main body 246 is automatically returned to the original position (see FIG. 14) by the action of the spring 248 and the upper portion of the reservoir 18 is closed.

  15 shows an example in which the lid main body 246 is provided so as to be substantially horizontal in the closed state, but as described above, the reduced diameter portion 240 is provided so as 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.

Each of the above-described embodiments is an example in which the discharge mechanism provided for each is controlled only by communication between the simple toilet device 10 and the existing toilet device 3.

  The embodiment shown in FIG. 16 uses the portable terminal device 400 in addition to such a control mode, and this portable terminal device 400 can also control the discharge mechanism of the simple toilet device 10 and the existing toilet device 3. It is.

  Therefore, the mobile terminal device 400 includes a control unit 402 configured by a CPU as shown in FIG. 17, which is associated with a transmission / reception unit 404, and is transmitted from the simple toilet device 10 or the existing toilet device 3 by the antenna 406. Status signal can be received. The control unit 402 decodes the received status signal and sends information corresponding to the decoded content to the notification unit 410.

  In this case, since it is necessary to identify the simple toilet device 10 or the existing toilet device 3, a header is added to the status signal, and the status signal from which toilet device is determined by the identifier added here. Can be identified.

  As the notification means 410, the case where it comprises the buzzer 412, the indicator lamp 414, such as LED, and the character display part 416, such as LCD, is shown. The character display unit 416 displays the source of the status signal. Further, an operation signal from an operation unit (operation key) 420 is supplied to the control unit 402. The operation unit 420 can select either the simple toilet device 10 or the existing toilet device 3 to instruct the discharge process. At this time, the instruction from the portable terminal device 400 is given priority, and an instruction to wait for the discharge process is sent to the other toilet device.

  When the portable terminal device 400 is used in this manner, the usage status of the toilet device can be grasped even from a remote location, which is very convenient when a caregiver or the like uses it because it is possible to grasp who is using the toilet device. .

  In the example of FIG. 1, the relationship between the simple toilet device 10 and the existing toilet device 3 is a (one-to-one) relationship. In some cases, the existing toilet device 3 may be connected to a plurality of simple toilet devices 10.

  In this case, as shown in FIG. 18, a plurality of, for example, three simple toilet devices 10 (10A to 10C) are connected to one existing toilet device 3. Wash water is supplied from the existing toilet device 3 to each of the simple toilet devices 10A to 10C through the water supply hose 12. And after connecting the discharge hose 14 of each simple toilet apparatus 10A-10C, it connects with the discharge port 114 (refer FIG. 5) of the existing toilet apparatus 3, and is used.

  In the case of such a (many-to-one) configuration, for example, the control unit 300 provided in the existing toilet device 3 is used as a master unit (master), and the control unit 50A provided in the simple toilet devices 10A to 10C. ˜50C may be used as a slave (slave). The discharge prohibiting process for the discharging mechanism and the canceling process thereof are all managed on the control unit 300 side.

  For example, when a state signal is sent from the control unit 50A, the control unit 300 transmits a use state signal to the control units 50B and 50C, and the control units 50B and 50C perform a discharge prohibition process. Use is avoided. Moreover, when the existing toilet apparatus 3 is used, discharge | emission prohibition process is performed with respect to all the control parts 50A-50C, and discharge | emission of the filth to the existing toilet apparatus 3 in use is prohibited. Therefore, management of the entire toilet system is facilitated. Of course, it is possible to manage and control other toilet devices by using the toilet device that first transmitted the status signal as a master. In this case, this status signal is a discharge prohibition instruction signal for other toilet devices.

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