Description

  The present invention relates to a portable toilet device, and more particularly to a portable toilet that can be used indoors. Specifically, in order to efficiently carry out the prevention and pumping of filth, it has a pulverizing means for pulverizing excrement (dirt) such as defecation and a means for pumping the crushed filth in the reservoir part of the toilet body. The opening / closing lid is provided on the lower surface side of the reduced diameter portion provided at the upper portion of the reservoir portion, so that the filth and the like can be reliably pumped while preventing the filth from being scattered.

  Portable elderly toilet devices have been developed for elderly people who need nursing care and for people who are physically inconvenient and difficult to visit existing toilets in the room (for example, Patent Document 1).

  This portable toilet device is configured as a chair so that it can be installed indoors, and can be used by sitting on a chair. The portable toilet device is provided with a water supply hose for flowing cleaning water into the toilet bowl, a discharge hose for discharging the waste, and a means for pumping the waste. The water supply and discharge are performed using the existing toilet.

Japanese Patent Laid-Open No. 2001-275858

  By the way, since the technique disclosed in Patent Document 1 is to discharge filth in the toilet bowl by pumping filth using a drainage pump, the drainage pump also has a certain amount of capacity (power). It cannot effectively discharge filth. If the capacity is not enough, filth stays in the middle of the discharge hose, which makes it unsanitary.

  In addition, the drainage pump must always be filled with liquid, and since wash water is used as the pumping medium, it is necessary to pump and discharge a large amount of wash water in order to clean up the waste in the discharge hose. There is.

  In order to solve this problem, it is conceivable to block the upper surface of the sewage reservoir and increase the internal pressure of the spillage, and then discharge the mixture (fluid) of crushed sewage and accumulated water. In that case, how to increase the internal pressure of the space in the reservoir (the space in contact with the accumulated water) is the point of success or failure of effective waste discharge.

  Accordingly, the present invention solves such a conventional problem, and in particular, sewage is pulverized and provided with an open / close lid for preventing spillage of dust, and the inside of the reservoir (the upper surface space of the trap water) is effective. The present invention proposes a portable toilet device that can be used indoors by providing a means that can pressurize the sewage so that the sewage can be reliably discharged while preventing the sewage from scattering.

In order to solve the above-mentioned problem, a portable toilet device according to the present invention described in claim 1 includes a water supply outlet for discharging purified water from the vicinity of the opening of the toilet, and a pool provided at the bottom of the opening. And a toilet body provided with a discharge port communicating with the reservoir, a pulverizer for filth disposed in the reservoir, and a pulverized material feed means for pumping the crushed filth provided in the reservoir The portable toilet device is provided with an open / close lid that seals the pool portion, and the toilet body is formed between the opening of the toilet and the pulverization pumping means and has a smaller diameter than the opening of the toilet. The opening / closing lid is attached to the lower surface side of the reduced diameter portion having a smaller diameter than the opening of the toilet bowl via a hinge mechanism, and is biased toward the reduced diameter portion so that the peripheral edge of the opening / closing lid is It provided to abut the edge of the reduced diameter portion, at closing the reduced diameter portion In addition, the reservoir is sealed by closing the reduced diameter portion, and is disposed inside the toilet body so that the area of the reservoir is smaller than the area of the opening of the toilet with the reservoir being sealed, and the pulverized material is fed under pressure. The means is characterized in that compressed air is supplied to a reservoir portion that is closed and closed by an opening / closing lid.

  In the present invention, a toilet body provided with a water supply port, a discharge port, a pulverizing means and a pulverized material pressure feeding means is used. In this example as an opening / closing means for opening and closing the water supply port and the discharge port, a water supply hose and a discharge hose are connected via an electromagnetic valve.

  The toilet body is provided with a reduced diameter portion (annular flange portion) having a diameter smaller than that of the opening of the toilet body, and an opening / closing lid capable of closing the reduced diameter portion at an upper portion of the filth reservoir. The opening / closing lid is normally urged so as to close the reduced diameter portion and is in contact with the edge of the reduced diameter portion.

  When filth or the like falls on the opening / closing lid, the tip of the opening / closing lid is separated from the edge of the reduced diameter portion by the weight, and the filth falls automatically into the accumulation portion by its own weight.

  A waste material crushing means is provided in the reservoir of the toilet body. When the crushing means is composed of a motor and crushing blades, the height of the crushing blades is selected so that all or part of the blades are submerged under the surface of the trap water in the reservoir.

  After defecation, the lid is automatically closed, so that the reservoir is automatically sealed again. Thereby, deodorization from a filth and concealment of a grinding means can be performed. At the same time, the crushing means is driven to crush the filth. After the waste is pulverized, compressed air is sent into the reservoir to pressurize the reservoir. Then, the pulverized fluid is pumped by opening the discharge solenoid valve. Flowing material can be discharged into the existing toilet by this pumping process. Thereafter, trap water (wash water) is supplied into the reservoir. A part of the washing water temporarily accumulates on the upper surface side of the opening / closing lid, and a part flows into the accumulation part via the edge of the reduced diameter part. When cleaning water accumulates on the upper surface side of the opening / closing lid, the opening / closing lid opens by its own weight (away from the edge of the reduced diameter portion). When the opening / closing lid is opened, all of the cleaning water accumulated on the upper surface falls into the reservoir and is trapped in the reservoir. As a result, a predetermined amount of trap water can be trapped in the reservoir portion for the next use.

  The inside of the reservoir is pressurized while the open / close lid is in contact with the lower edge of the reduced diameter portion. At that time, pressure is also applied to the opening / closing lid from the back side, but since the opening / closing lid is provided to have an area smaller than the area of the opening of the toilet, the load generated by the pressure acting on the opening / closing lid is small. Thus, the structure of the opening / closing lid can be simplified. In addition, since the pressure applied to the opening / closing lid can be received by the edge of the reduced diameter portion, the opening / closing lid is damaged by the pressurization (about 2 atmospheres) in the reservoir, or the sealed state becomes worse and the compressed air Most of the water does not leak to the top of the reservoir. Accordingly, the compressed air can be effectively applied to the reservoir portion side, the waste can be pumped with a small amount of compressed air, and a small air compressor can be used as the air compressor as the pumping means.

  Since the crushed filth is a fluid, the fluid can be easily discharged to the existing toilet side through the discharge hose together with trap water (wash water) if compressed air is applied to the reservoir. Therefore, the flow material does not stay in the discharge hose.

  Since the opening / closing lid is used, when the filth is pulverized, it is possible to prevent the filth from being scattered in the toilet body, so that the toilet body does not become unsanitary.

  When the simple toilet device is moved or removed, the drain switch is operated. When this drain switch is operated, compressed air from the air compressor is sent into the reservoir, and the trapping water in the reservoir is discharged to the existing toilet by opening the discharge solenoid valve when the internal pressure in the reservoir rises. And the reservoir can be emptied.

  When cleaning water is introduced from the branch pipe side of the existing toilet, if a tank filled with a disinfectant or cleaning agent is provided on the branch pipe side, the simple toilet device can be cleaned at the same time as the cleaning of the existing toilet. A simple toilet device can be provided.

If an air motor is used as the crushing means instead of an electromagnetic motor, the air compressor for the air motor can be used also as the air compressor for the pressure feeding means.
When the drain hose is not connected to the toilet of the existing toilet but is simply poured, the tip of the drain hose is guided into the toilet of the existing toilet. At this time, if the tip opening of the discharge hose is gradually widened, the flow rate (flow velocity) at the tip opening can be reduced or the internal pressure can be dispersed. Thus, when ejecting from the tip of the discharge hose, the tip of the discharge hose does not run out due to the reaction force of the jet pressure of the fluid.

  If the water supply hose and the discharge hose are integrated, these hoses can be easily attached, removed and routed.

In the present invention, the sewage pulverizing means is provided in the toilet body reservoir, the pulverized material pressure feeding means is provided above the reservoir, and the open / close lid is provided on the lower surface side of the reduced diameter part.
According to this, the fluid in the reservoir can be reliably pumped and discharged. In addition, since the pressure received by the opening / closing lid when compressed air is sent into the reservoir can be received by the edge of the reduced diameter portion, the opening / closing lid can be prevented from being damaged or the compressed air can be prevented from leaking. As a result, downsizing of the pressure feeding means can be achieved.

  Next, a preferred embodiment of the portable toilet device according to the present invention will be described in detail with reference to the drawings. The portable toilet device according to the present invention is particularly preferably a toilet device equipped with a so-called warm water cleaning toilet seat with a butt cleaning function. In the following explanation, explanation of the equipment of the warm water washing toilet seat is omitted. The portable simple toilet device is applied to a Western toilet type.

  FIG. 18 shows an application example of the present invention. In this example, an existing toilet 3 is installed facing the corridor 2 of the house 1. A toilet 4 and a washing water injection tank 5 are installed in the existing toilet 3. In this example, a room 6 serving as a bedroom is located along the corridor 2, and a bed 7 is placed in the room 6, for example.

  The portable toilet device 10 according to the present invention is provided with water supply means and discharge means, the water supply means is connected to the water supply, and the discharge means is connected to the sewer. Usually, the water supply means (water supply hose 12) and the discharge means (discharge hose 14) are connected by using the water supply pipe and the discharge pipe of the existing toilet 4, respectively.

  FIG. 1 is a cross-sectional view of an essential part showing an example of a portable toilet device 10 according to the present invention. This portable 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 strong, and not only a box shape but also a chair type with an armrest, for example, is 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 molded 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. Note that a portion having a cross-sectional shape of approximately “he” is generally called an “S” trap. Therefore, in this example, a 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. . In addition to the illustrated shape, P-type, U-type, saddle-type, and the like are conceivable as the shape of the discharge portion 22 communicating with the reservoir portion 18. These shapes can provide the same effects.

  The electromagnetic valve 24 is controlled so as to open only when trap water (water containing dirt) in the reservoir 18 is discharged out of the toilet bowl, and is closed when the toilet is not in use. This is to prevent water leakage. In addition to preventing water leakage, the electromagnetic valve 24 also has a function of preventing compressed air from leaking when the inside of the reservoir 18 is pressurized using an air compressor (described later) that constitutes a pressure feeding means.

  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. A branch pipe is used as the connection pipe 30, and an electromagnetic valve 32 for controlling the washing water is attached to the connection pipe 30 that faces the water supply port 28. This is because water supply from the water supply hose 12 connected to the connection portion 34 can be controlled by the electromagnetic valve 32.

  A washing hose (cleaning pipe) 240 is also connected to the branched connecting pipe 30 via an electromagnetic valve 33. The front end of the cleaning hose 240 is provided so as to protrude above the surface of the trap water in the reservoir 18. By the water injection (actually injection) by the cleaning hose 240, the inside of the reservoir 18 and the back surface of the open / close lid 212 are cleaned as will be described later.

  A rubber-like water leakage prevention pipe 29 is inserted between the water supply port 28 and the wall surface 18a, and a water leakage prevention pipe 242 is also inserted in the pool portion 18 through which the cleaning hose 240 penetrates, thereby leaking water to the outside. I'm trying to prevent it.

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

  The crushing means 40 can be composed of a motor (electromagnetic motor) 42 and crushing blades 44, and in FIG. 1, 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 watertightly engaged with the bottom of the reservoir 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 inside the bottom plate 20c. Each drive of the electromagnetic valve 24 for discharge, the electromagnetic valves 32 and 33 for water supply, the motor 42 and the like described above is controlled by the control unit 50 at a predetermined timing for a predetermined time. A power switch 52 for the control unit 50 is provided on the main body back surface portion 20b, and is an upper surface portion of the main body, and an open / close switch 55 (described later) is provided on the lower surface of the toilet lid 23.

  The portable toilet device 10 according to the present invention further has the following structure. As shown in FIG. 1, 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 230 is provided above the pool portion 18 and slightly above the attachment position of the pressure feeding means 200. An opening / closing lid mechanism 210 is provided on the lower surface of the reduced diameter portion 230 so as to close the reduced diameter portion 230 and seal the pool portion 18.

  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 to the accumulation portion 18 side through the attaching 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.

  Even if the toilet body 20 is not provided with the air compressor 200 but a mechanism that takes compressed air from the outside of the portable simple toilet device body, the same effect can be expected.

  The reduced diameter portion 230 is configured as an annular flange portion, and protrudes by a predetermined length toward the inner surface of the pool portion 18. The feed pipe 204 described above is located between the trap water in the reservoir 18 and the reduced diameter portion 230.

  As is clear from FIG. 1, the entire diameter-reduced portion 230 is provided to be slightly inclined toward the discharge portion 22. On the lower surface side of the reduced diameter portion 230, an opening / closing lid mechanism 210 that can close the reduced diameter portion 230 is provided. As the opening / closing lid mechanism 210, a rotating type and a sliding type are conceivable. The example of FIG. 1 is a rotation type.

  In this example, since it is a rotary type, it has a lid body 212 that constitutes the open / close lid mechanism 210, and one end of the lid body 212, in the example shown in the figure, the right end portion serves as a pivot shaft portion 214. The shaft 214 is pivotally supported with respect to the toilet body 20 so that the shaft 214 is positioned on the lower surface 232 of the reduced diameter portion 230. This pivotal support is pivotally supported by the toilet body 20 in a watertight manner.

  The lid body 212 is urged so that the peripheral surface thereof is in contact with the lower surface edge 234 of the reduced diameter portion 230. The lid body 212 has a shape along the lower surface edge portion 234, and normally, the rotation shaft portion 214 and the wall surface of the lower surface portion 232 are sealed so that the inside of the reservoir portion 18 can be sealed by contacting the lower surface edge portion 234. An urging spring 216 is wound between them.

  Here, as described above, the reduced diameter portion 230 is provided so as to be inclined slightly toward the discharge portion 22, so that the lid body 212 itself constituting the open / close lid mechanism 210 is also inclined and attached to the discharge portion 22 side. . If the lid main body 212 is tilted and attached in this manner, excrement that has fallen on the upper surface of the lid main body 212 does not remain and can be dropped into the pool portion 18.

  The above-described cleaning hose 240 has its tip end attached to the reservoir 18 at an angle such that cleaning water can be sprayed onto both the back side of the lid body 212 and a part of the peripheral surface of the reservoir 18. In this example, as shown in FIG. 1, in the vicinity of the rotation shaft portion 214 of the lid body 212, it is attached and fixed in a liquid-tight manner to the lower side thereof.

  A water supply hose 12 and a discharge hose 14 are connected to the toilet main body 20 configured in this way, and they are guided to the existing toilet 3.

FIG. 3 shows an outline of the existing toilet 3.
FIG. 3 illustrates the existing toilet 4 provided with the warm water washing toilet seat 80. In this case, a branch pipe 84 is connected to a water pipe (water supply pipe) 82, and a first branch port 86 is provided on the side of the water pipe 82 in the branch pipe 84. A hose 87 for a hot water washing toilet seat is provided here. Connected. A second branch port 88 is provided closer to the end than the first branch port 86, and a hose 89 for washing water is connected thereto.

  In this example, the branch pipe 84 having such a branch configuration is used, a check valve 90 is installed between the first and second branch ports 86 and 88, and the end portion of the branch pipe 84 is used. A connecting portion 92 for the water supply hose 12 is provided. A connecting portion 60 </ b> A provided at the tip of the water supply hose 12 is connected to the connecting portion 92.

  In this way, by providing the new branch pipe 84 and attaching the water supply hose 12 thereto, the wash water can be supplied to the portable simple toilet apparatus 10. It should be noted that the check valve 90 is installed between the first and second branch ports 86 and 88 in the event that water from the hose 89 or the water supply hose 12 side flows backward and is supplied to the hot water washing toilet seat side. This is to prevent them from mixing with each other.

  A tank 96 filled with a disinfectant solution is inserted into the disinfectant solution connecting portion at the end of the branch pipe 84. By using the disinfectant, the sanitary condition of the portable toilet device 10 as well as the existing toilet 3 can be improved. Furthermore, the discharge hose can be cleaned at the same time. Note that the tank 96 is not necessarily provided, and may be provided as necessary.

  If the water distribution system of the existing toilet is diverted in this way, the portable simple toilet device 10 can be used with a simple extension work in which only the branch pipe 84 is attached.

  The discharge hose 14 may be piped so that it can be discharged directly into a discharge pipe, for example, a discharge pipe in the existing toilet 3, but the discharge hose 14 is simply guided to the toilet 4 and sewage is directly poured into the toilet 4 That is. Alternatively, the toilet 4 is provided with a discharge outlet, and a discharge hose 14 is connected to the toilet 4 to discharge the toilet 4.

  The embodiment shown in FIG. 4 is an example in which the connecting portion 114 provided in the toilet 4 is connected. In this case, the toilet body 108 is improved. As shown in FIG. 4, the toilet body 108 has a discharge pipe 110. The toilet body 108 is provided with a discharge outlet 112 on the upper side of the reservoir and connected on the back side thereof. The connecting portion 62 </ b> B of the discharge hose 14 is connected to the portion 114.

  When the existing toilet 4 is improved in this way, there is a difference in height between the portable toilet device 10 and the existing toilet 4, and when the toilet 4 is higher, there is a risk that fluids may stay in the discharge hose 14. is there. Therefore, the pressure of the air compressor 200 described above is adjusted so that it can be completely discharged.

  Although not shown, it is also possible to provide a closing lid that closes the upper part of the reservoir including the discharge outlet 112 and close the closing lid in connection with the discharge process of the portable toilet device 10. it can. In this case, the closing lid is preferably an electric closing operation.

  Thus, when water supply and discharge are performed using the existing toilet 3, the supply / discharge pipes shown in FIG. 5 and below are used. FIG. 5 shows an example of the water supply hose 12, and FIG. 6 shows an example of the discharge hose 14. 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 portable toilet device 10, each of the one end 12a and the other end 12b Connecting portions 60A and 60B with check valves are attached.

  Similarly, the discharge hose 14 is provided with connecting portions 62A and 62B with check valves at one end 14a and the other end 14b. In this case, one end 14a is an end connected to the portable toilet device 10 side, and the other end 14b is an end 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 (crushed material) obtained by pulverizing dirt or the like flows in the pipe, a vinyl hose having the same diameter as the water supply hose 12 or a slightly thicker diameter is used. can do. This is not a solid waste, but a fluid mixed with washing 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. 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 metal fitting 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.

  For example, as shown in FIG. 7, the connecting portion 60 (62) with a check valve is provided with a valve operating chamber 64 having a rectangular cross section in the hollow interior of a main body 63, and a sphere 65 that acts as a valve and a pressure spring for the same. 66, and the valve is opened when the water pressure acts in the direction of arrow a. This prevents backflow from both the portable 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 portable toilet device side and, for example, the sewer pipe side of the existing toilet, the check valve sphere Protruding portions (not shown) 65 retreating against the pressing spring 66 are provided on each of the portable toilet device side and the sewer pipe side so that when the connecting portion 60 (62) is connected, the internal valve When the connection is released, the internal valve is closed and the liquid in the hose is prevented from leaking 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 of the portable simple toilet device 10. In addition to the power switch 52 described above, an open / close switch 55 and a drain switch 244 are provided, and their on / off signals are supplied to the controller 50.

  The power switch 52 is turned on when the portable toilet device 10 is installed. On the other hand, the open / close switch 55 is a switch that is turned on / off in association with opening / closing of the toilet lid 23 for closing the upper portion of the toilet seat 21. Therefore, as shown in FIG. 1, in this example, an open / close switch 55 (open / close detection sensor switch or the like) is attached to the lower surface of the toilet lid 23 so as to face the toilet lid 23. The drain switch 244 can be provided behind the toilet lid 23, for example. This is because the usage frequency is low.

  The drive state of the discharge solenoid valve 24, the water supply solenoid valve 32, the cleaning solenoid valve 33, the grinding motor 42, and the air compressor 200 described above is controlled by a control signal from the control unit 50 constituted by the CPU. .

  FIG. 9 shows an example of the control timing. In the case of this portable simple toilet device 10, when the toilet is not in use, the lid body 212 which is an open / close lid is in a closed state.

  The portable 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) (FIG. 9A). Use while the toilet lid 23 is open. When the excrement falls on the lid main body 212, the lid main body 212 is opened by its own weight, and the excrement falls into the trap water of the reservoir 18 (see FIG. 2). When the excrement falls, the lid body 212 is automatically closed. This is because the lid body 212 is always urged toward the reduced diameter portion 230 side.

  When the defecation is completed, the toilet lid 23 is closed (FIG. 9A). If it is determined that the lid is closed, the excrement is crushed over the period Ta (FIG. 9B). Instead of performing the operation of closing the toilet lid 23, the pulverizing process may be started by operating a start switch corresponding to the open / close switch 55 by manual operation. The pulverization processing time Ta is selected to be a time during which filth and toilet paper can be sufficiently pulverized. Usually, the time is set to 20 seconds or less, preferably about 5 to 10.

  When the pulverization process is completed, the air compressor 200 is driven, and compressed air is fed into the reservoir 18 and pressurized (FIG. 9E). The pressurization processing time Tb is set to a time during which the internal pressure in the reservoir 18 rises to a predetermined value (for example, 2 atm). The predetermined value of the internal pressure refers to a pressure at which fluid can be reliably pumped and discharged into the existing toilet 4 via the discharge hose 14. Actually, a time Tb at which the internal pressure is a predetermined value is preset, and this time Tb is counted.

  When the pressurization time Tb elapses, the discharge solenoid valve 24 is driven in a state where the air compressor 200 is driven, that is, in a state where compressed air is supplied into the reservoir 18 (FIG. 9D). When the discharge solenoid valve 24 is driven and the discharge port 27 is opened, the trap water (flowing material) in the reservoir 18 is pumped by compressed air and discharged to the discharge hose 14 side. Since the discharge hose 14 is connected to the existing toilet 4, the excrement crushed by the crushing means 40 is discharged to the existing toilet 4 side.

  Although the pumping period Tc differs depending on the installation length of the discharge hose 14, in order to prevent the flow material from remaining in the discharge hose 14, it is usually a relatively long time, for example, about 10 to 30 seconds. Is set.

  When the pumping period Tc elapses, the energization of the discharge solenoid valve 24 is released and the driving of the air compressor 200 is stopped (FIGS. 9D and 9E). Thus, the discharge port 27 is closed. Thereafter, the water supply electromagnetic valve 32 is operated to start water supply into the reservoir 18 (FIG. 9C). The water supply time Td is set to a water injection time in 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 standby state is established.

  In this example, as shown in FIG. 9C, the cleaning electromagnetic valve 33 is also operated in synchronization with the operation of the water supply electromagnetic valve 32. When this electromagnetic valve 33 is actuated, water is injected into the reservoir 18 via the cleaning hose 240, specifically, injection onto the back surface of the lid body 212 and injection onto the wall surface of the reservoir 18 are performed. Since the back surface of the lid main body 212 and the wall surface of the reservoir 18 are cleaned by this washing water jet, the lid main body 212 and the reservoir 18 can always be kept clean.

  Rather than simultaneously supplying water into the reservoir 18 and cleaning the lid body 212 and the like, the cleaning process is performed before supplying water into the reservoir 18, that is, after the fluid feed / discharge process is completed. The cleaning water at that time may be pumped and discharged at the same time. Therefore, water supply into the reservoir 18 is performed after the solenoid valve 24 is closed thereafter.

  When the portable toilet device 10 is moved or removed, it is preferable that the trap water in the reservoir 18 is discharged. This draining process is performed independently of the above-described discharge process. In that case, as shown in FIG. 10, the water drain switch 244 is turned on to operate the air compressor 200 (FIGS. 10A and 10B). When the air compressor 200 is started, the inside of the reservoir 18 is pressurized (FIG. 9C). When the pressurization process over the period Tf is completed, the discharge electromagnetic valve 24 is activated to open the discharge port for a predetermined period Tg (FIG. 9B).

  The trapping water can be discharged from the pool portion 18 by this pressure and pressure feeding. Then, the discharge solenoid valve 24 is closed after a little time ΔTf after the driving of the air compressor 200 is stopped. By doing so, the trap water discharge process (water drain process) is completed. Here, the period Tf may be set to the above-described time Tb, and the period Tg may be set to the time Tc.

  The first embodiment shown in FIG. 1 is a case where the opening / closing mechanism is configured as a pivoting type, but this can also be configured as a sliding type. In the case of the slide type, a mechanism is employed in which the lid body slides left and right on the upper part of the reservoir portion 18. An opening / closing drive unit is associated with the lid body.

  An example is shown in FIG. In FIG. 11, an electromagnetic solenoid 218 is used as the opening / closing drive unit 213 connected to the lid body 212. 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 part of the lid body 212 described above.

  As shown in FIG. 12, an example of the lid body 212 is a flat plate-like shape along the inner peripheral shape of the reservoir portion 18. In this example, the lid main body 212 is shaped like a lever 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. 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.

  A diameter-reduced portion 230 similar to that shown in FIG. 1 is provided inside the toilet body 20 with which the lid body 212 is in contact. The peripheral surface portion of the lid main body 212 is in contact with the lower surface edge portion 234 of the reduced diameter portion 230, and the reservoir portion 18 is sealed by the contact.

  FIG. 11 shows a state in which the lid main body 212 is closed, and the inside of the reservoir portion 18 is sealed by the lid main body 212. On the other hand, FIG. 13 shows a state in which the lid body 212 is retracted and the reservoir 18 is opened.

  Such an advancing / retreating operation with respect to the lid body 212 is performed by energizing and releasing the electromagnetic solenoid 218, and the stroke thereof is the first switch 222 provided on the lid body 212 side of the electromagnetic solenoid 218 and the wall surface 18 a of the toilet body 20. It is detected by a second switch 224 provided on the side. The end of the stroke of the lid 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 required. When the air compressor 200 is operated in this closed state, the compressed air is supplied into the reservoir 18 and pressure acts on the trap water. For the same reason as described above, the crushed material in the reservoir 18 Is pumped to the discharge hose 14 side. Here, the pulverized material refers to a flow material obtained by mixing the filth crushed as described above and trap water.

  Further, since the tip peripheral surface of the lid main body 212 is brought into contact with the lower surface edge 234 side of the reduced diameter portion 230, the pressure acting on the lid main body 212 when compressed air is sent from the air compressor 200 into the pool portion 18. Is received by the lower surface edge 234. As a result, damage to the lid body 212 can be avoided.

  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.

  Therefore, the flow material does not stay in the discharge hose 14. 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. 14 shows an example of a control system provided in the simple toilet apparatus 10 shown in FIG.
In this example, the control unit 50 is supplied with signals from the first and second stopper switches 222 and 224 described above. The controller 50 controls the electromagnetic solenoid 218 for the opening / closing lid. The first and second switches 222 and 224 are switches that are turned on / off by the stroke of the lid body 212.

  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.

  FIG. 15 shows an example of the control timing. The opening operation of the toilet lid 23 is detected by the open / close switch 55 (FIGS. 15A and 15B). When the toilet lid 23 is opened, the lid body 212 is opened by energizing the electromagnetic solenoid 218 (FIG. 15C). The stroke Tx of the lid main body 212 is detected by the first switch 222, and the energization of the electromagnetic solenoid 218 is released when the first switch 222 is turned on (FIG. 15D).

  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. 15E).

  When the lid main 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. 15F). The pulverization processing time Ta is selected as a time during which filth and toilet paper can be sufficiently pulverized. The time is selected to be 20 seconds or less, for example, about 5 to 15 seconds.

  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 to pressurize the accumulation portion 18 for a predetermined time Tb.

  When the internal pressure of the reservoir 18 rises to a predetermined pressure (for example, 2 atmospheres), the discharge electromagnetic valve 24 is opened to form a discharge path (FIGS. 15H and I). 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 Tc.

  The predetermined time Tc 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, 10-30. It can be set to about seconds.

  When the predetermined time Tc elapses, the operation shifts to the opening operation of the lid body 212 (FIG. 15C). 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 portion 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 Td (FIG. 15G). The predetermined time Td is set to a water injection time in 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 to the reservoir 18 is completed, the lid main body 212 is closed and returns to the initial state (FIGS. 15C and 15D). 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. The above-described opening / closing timing of the electromagnetic valve is merely an example. It can be changed as appropriate.

  FIG. 16 shows another example of attachment of the crushing means 40. In this example, a mounting recess 67 having a predetermined depth and size is provided integrally with the reservoir 18 on the bottom side of the reservoir 18. The crushing motor 42 is inserted and fixed in the mounting recess 67 through a vibration-proof rubber material 69 or the like. The mounting recess 67 is closed by a closing plate 68 made of a rubber material or a plastic material, and the mounting recess 67 is watertightly closed.

  In order to achieve watertightness with respect to the mounting recess 67, the bottom of the reservoir 18 that contacts the closure plate 68 is somewhat recessed, and the closure plate 68 is fixed to the bottom of the reservoir 18 by screws 70 or the like. In this way, the grinding means 40 can be attached. In this example, the configuration of the motor 42 and the pulverization blade 44 as the pulverization unit 40 has been described. However, instead of the pulverization blade, a configuration such as a screw, a blade, or a cylindrical roller having protrusions on the outer periphery may be used. The structure which arrange | positioned the motor rotating shaft horizontally may be sufficient.

  FIG. 17 shows a connection example between the existing toilet 3 and the discharge hose 14. In the above description, the connecting portion is provided in the toilet 4 situation, but the example in FIG. 17 is an example in which the toilet 4 can be discharged without modification, and the discharge hose 14 is passed between the toilet 108 and the toilet seat 118. This is an example. In this case, if the simple hose restraint 120 is attached to the toilet seat 118 (118a), the stability of the discharge hose 14 is increased.

  As the discharge hose 14 used in this case, the connecting tool 62B is unnecessary. In this case, it is preferable that the tip end portion is opened in a trumpet shape as shown in FIG. Although not shown, the apparent upstream underwater tip opening can be widened by forming a split groove in the tip.

  This is because if the tip opening of the discharge hose 14 is gradually widened, the flow rate (flow velocity) at the tip opening can be reduced or the internal pressure can be dispersed. However, the tip of the discharge hose 14 does not run out due to the reaction force of the jet pressure of the fluid.

  If the water supply hose 12 and the discharge hose 14 are integrated, the hose 12, 14 can be easily attached, removed and routed regardless of the presence or absence of the connecting tool.

  Although not shown, if an air motor is used as the crushing means 40 shown in FIG. 1 instead of an electromagnetic motor, the air compressor for the air motor can also be used as the air compressor 200 for the pressure feeding means.

  In this invention, it can be used as a care assisting device such as a care facility or home care.
