The water supply mechanism 8 is connected to the water supply tank 3 and the buttocks cleaning nozzle 5. The water supply mechanism 8 is configured to be able to supply water so that the cleaning water of the water supply tank 3 is discharged from the buttocks cleaning nozzle 5 without using an external drive source. The water supply mechanism 8 is a water supply device that does not require power. Since the toilet bowl cleaning nozzle 7 is also provided in the present embodiment, the water supply mechanism 8 is also connected to the toilet bowl cleaning nozzle 7. The water supply mechanism 8 is configured so that the cleaning water of the water supply tank 3 can be discharged from the toilet bowl cleaning nozzle 7 without using an external drive source.

As shown in FIGS. 3 and 4, the water supply mechanism 8 has a water circuit 80. The water circuit 80 includes a manual pump 6, a water suction pipe 62, a first tube 81, a second tube 82, a third tube 83, and a switching valve 84. The manual pump 6 is a positive displacement liquid pump in which the pump has a bag-like structure. The bag-shaped structure is a structure of a pump having flexibility and shape restoration. The positive displacement liquid pump is a liquid pump in which check valves that regulate the water transfer direction to the water supply side are mounted on the primary side and the secondary side of the pump. The water supply mechanism 8 is configured so that the washing water can be sucked up from the water supply tank 3 by the manual pump 6 and supplied to the water circuit 80.

The manual pump 6 includes, for example, a bellows type pump operating unit 61. The pump operating portion 61 is provided at the rear end portion of the upper component 12 so as to project upward. Specifically, it is provided at the rear end on the right hand side when the user is seated on the toilet seat 13. The pump operating unit 61 projects upward from the upper surface of the upper component 12.

As shown in FIGS. 1 and 3, the water absorption pipe 62 and the first tube 81 are connected to the lower end of the bellows type pump operation unit 61. The water absorption pipe 62 extends in the vertical direction H, and the lower end opening is located at the lower part of the water supply tank 3. In the state where the washing water is stored in the water supply tank 3, the lower end opening of the water absorption pipe 62 is buried in the washing water. The upper end of the water absorption pipe 62 communicates with the manual pump 6 and the first tube 81.

The switching valve 84 is arranged in the water supply tank 3 and is fixed to the outer wall of the water supply tank 3 which is the housing of the upper component 12. The switching handle 85 of the switching valve 84 is exposed to the outside on the outside of the toilet bowl 4 in the width direction W. The switching handle 85 corresponds to the handle. A handle recess 123 in which the outer surface of the upper component 12 is recessed is formed on the side surface 122 on one side of the width direction W of the upper component 12. In the present embodiment, the steering wheel recess 123 is formed on the right hand side when the user is seated. The switching valve 84 is fixed to the wall of the handle recess 123, and the switching handle 85 projects. The switching handle 85 is housed in the handle recess 123, and is provided so that the switching handle 85 does not protrude outward. The handle recess 123 is open upward and sideways, and is arranged at a position where the user can easily rotate the switching handle 85 from either the upper side or the side.

The switching handle 85 is located inside the outer edge of the upper component 12 in the vertical direction H, the width direction W, and the front-rear direction D. In the vertical direction H, the width direction W, and the front-rear direction D, a part of the housing of the upper component 12 is arranged outside the switching handle 85. Since the switching handle 85 does not protrude from the outer edge of the upper component 12, it is difficult for an external article or the like to come into contact with the switching handle 85, and damage is prevented. The vertical direction H, the width direction W, and the front-rear direction D correspond to the vertical and horizontal height directions.

The first tube 81 is connected to the pump operation unit 61 and the switching valve 84. The second tube 82 is connected to the switching valve 84 and the buttocks cleaning nozzle 5. The third tube 83 is connected to the switching valve 84 and the toilet bowl cleaning nozzle 7. In the present embodiment, since the toilet bowl cleaning nozzle 7 is provided, the third tube 83 is branched into two on the downstream side of the switching valve 84 and is connected to each toilet bowl cleaning nozzle 7.

The water supply path is switched to either the second tube 82 or the third tube 83 depending on the switching position of the switching handle 85. In the water supply mechanism 8, the water absorption pipe 62 draws the washing water in the water supply tank 3 by causing the internal pressure of the manual pump 6 to change by the manual operation in which the user grabs the pump operation unit 61 and repeats compression and decompression a plurality of times. Suck and let water flow to the first tube 81 side. The washing water supplied to the first tube 81 flows to either the second tube 82 or the third tube 83 via the switching valve 84 according to the switching position of the switching handle 85.

A toilet seat 13 and a toilet lid 14 are further provided on the upper part of the upper component 12. A support portion 124 having a rectangular shape in a plan view is provided between the pump operation portion 61 of the manual pump 6 and the water supply port 17 at the center of the rear end portion of the upper component 12 in the width direction W. The support portion 124 is formed with support side surfaces 125 along the vertical direction H on both sides in the width direction W. As shown in FIG. 1, each support side surface 125 is formed with a support shaft 18 of a toilet seat 13 and a toilet lid 14. The toilet seat 13 and the toilet lid 14 have known shapes. Support holes 19 (not shown) are formed in the toilet seat 13 and the toilet lid 14, respectively. Each support hole 19 is engaged with the support shaft 18, and the toilet seat 13 and the toilet lid 14 are attached to the upper component 12. The toilet seat 13 and the toilet lid 14 are rotatably attached around the support shaft 18.

Connecting tools 9 are attached to both side surfaces 122 of the upper component 12 in the width direction W. The connector 9 is configured to be engaged with the connecting portion 114 of the lower component 11 from the outside in the width direction W. When the connector 9 engages with the connecting portion 114 of the lower component 11, the upper component 12 is fixed to the lower component 11. When the connector 9 is disengaged from the connecting portion 114, the upper component 12 is in a separable state from the lower component 11.

Next, the usage mode of the toilet bowl device 1 will be described. Before use, wash water is stored in the water supply tank 3. The water supply lid is opened, and the washing water is stored from the water supply port 17 up to a predetermined full position. The water supply lid is closed, and the upper part 12 is placed on the upper part of the lower part 11. At this time, when the connecting tool 9 of the upper component 12 is aligned with the connecting portion 114 of the lower component 11, the discharge port 41 of the toilet bowl 4 is positioned at the opening 115 of the lower component 11. When the connector 9 is connected to the connecting portion 114, the upper component 12 is engaged with the lower component 11.

The switching handle 85 is set in advance at a position where the water circuit 80 is passed to the second tube 82 side. The opening / closing operation unit 162 of the lid mechanism 16 is pushed into the rear R, and the toilet bowl 4 and the filth storage tank 2 are separated by the slide plate 161. The buttocks cleaning nozzle 5 is adjusted in advance so that it faces forward F and upward.

The user opens the toilet lid 14 and sits on the toilet seat 13. After the stool, the user holds the pump operation unit 61 with his right hand and repeats the manual operation of compressing and decompressing the pump operation unit 61 a plurality of times. As a result, the internal pressure of the manual pump 6 rises, and the washing water is assembled from the water absorption pipe 62 and flows to the second tube 82 side. Due to the internal pressure of the manual pump 6, the washing water is vigorously discharged from the water discharge port 51 of the buttocks washing nozzle 5. When the cleaning water is discharged from the buttocks cleaning nozzle 5, the cleaning water is applied to the user's buttocks, and the buttocks can be washed.

The user manually adjusts the direction of the water discharge port 51 of the buttocks washing nozzle 5 to a desired direction at an arbitrary timing before and after the stool. The position for washing the buttocks when seated differs depending on the user. Since the toilet device 1 can adjust the direction of the water discharge port 51 of the buttocks washing nozzle 5 to an arbitrary direction, the direction of the water discharge port 51 of the buttocks washing nozzle 5 can be adjusted to the optimum position for each user.

After cleaning the buttocks, the switching handle 85 is rotated to switch the water supply path of the switching valve 84 to the third tube 83 side. Subsequently, when the pump operation unit 61 is manually operated as in the case of cleaning the buttocks, the cleaning water is discharged from the toilet bowl cleaning nozzle 7. The cleaning water discharged from the toilet bowl cleaning nozzle 7 flows downward along the inner surface 42 of the toilet bowl 4 while forming a swirling flow, and flows toward the discharge port 41. As a result, the inner surface 42 of the toilet bowl 4 is flushed with the washing water.

Subsequently, when the user pulls the opening / closing operation unit 162 toward the front F, the slide plate 161 moves to the front F, and the discharge port 41 and the opening 115 of the filth storage tank 2 communicate with each other. The toilet bowl 4 is provided above the sewage storage tank 2. Therefore, the excrement and the washing water collected inside the toilet bowl 4 flow into the filth storage tank 2 due to gravity. After that, when the opening / closing operation unit 162 is pushed backward R, the slide plate 161 moves to the rear R, and the opening 115 is closed.

The filth storage tank 2 has a capacity that can be used a plurality of times. Therefore, it is not necessary to dispose of the filth after each stool. When disposing of filth, the connection by the connecting tool 9 is released, and the upper part 12 and the lower part 11 are separated. Open the discharge lid of the discharge port 41 of the lower part 11 and dispose of the filth. When the amount of wash water in the water supply tank 3 is reduced, the water supply lid may be opened and the wash water may be replenished again. When the lower part 11 and the upper part 12 are connected again by the connecting tool 9, the toilet bowl device 1 can be used repeatedly.

The above-mentioned usage mode of the toilet bowl device 1 is an example, and the procedure at the time of use can be appropriately changed by the user. For example, the order of toilet bowl cleaning and buttocks cleaning differs depending on the user. For example, the slide plate may be opened in front of the stool, and the slide plate may be closed after the stool and the buttock washing and the toilet bowl washing are completed.

According to the toilet bowl device 1 according to the present embodiment, it is possible to provide a portable toilet bowl device in which the buttocks can be washed with washing water and can be carried.

In the toilet device 1 according to the above embodiment, the washing water can be sent to the buttocks washing nozzle 5 by the water feeding mechanism 8 without using an external drive source, and the washing water can be discharged from the buttocks washing nozzle 5. Therefore, it can be used even in places where there is no power supply equipment. Since the toilet device 1 can discharge the washing water from the buttocks washing nozzle 5 using the washing water stored in the water supply tank 3, it can be used even in a place where there is no water supply facility. The toilet device 1 can discharge the cleaning water from the buttocks cleaning nozzle 5 with sufficient water force by the water supply mechanism 8 even when there is no external drive source such as a power supply.

In the toilet bowl device 1, the orientation of the buttocks cleaning nozzle 5 can be manually adjusted. Therefore, the orientation of the buttocks cleaning nozzle 5 can be easily adjusted to a position desired by the user without using an external drive source.

The toilet device 1 can discharge cleaning water from the toilet bowl cleaning nozzle 7 by a manual liquid pump. Therefore, the toilet bowl 4 can be washed with water without using an external drive source. Therefore, the sanitary condition of the toilet device 1 can be maintained in a good state even when there is no external drive source such as a power supply.

In the toilet device 1, the discharge destination of the washing water is switched between the buttocks washing nozzle 5 and the toilet bowl washing nozzle 7 by the switching valve 84. That is, the cleaning water of the water supply tank 3 can be shared by the buttocks cleaning nozzle 5 and the toilet bowl cleaning nozzle 7. As a result, one water supply tank 3 can supply the cleaning water for the buttocks cleaning nozzle 5 and the toilet bowl cleaning nozzle 7. In addition, the configuration of the water circuit 80 can be simplified. As a result, the number of parts of the toilet bowl device 1 can be reduced, which contributes to weight reduction and cost reduction. As a result, the convenience of the movable toilet device 1 can be improved.

The toilet device 1 has a bag-like structure in which the pump has flexibility and shape restoration, and check valves that regulate the water transfer direction to the water supply side are mounted on the primary side and the secondary side of the pump. It is equipped with a positive displacement liquid pump. Therefore, the cleaning water can be discharged from the buttocks cleaning nozzle 5 with sufficient water force without using an external drive source. Similarly, the cleaning water can be discharged from the toilet bowl cleaning nozzle 7 with sufficient water force.

Since the toilet bowl device 1 includes the filth storage tank 2, it can be used even in a place where there is no sewerage facility.

According to the toilet bowl device 1 according to the present embodiment, for example, people in an area having a culture of washing the buttocks and in an area where the infrastructure is not well developed can also provide a toilet bowl device having excellent convenience. .. In addition, a comfortable toilet environment can be provided even in the event of a disaster or camping.

Since the waste storage tank 2 and the water supply tank 3 of the toilet bowl device 1 also serve as the housings of the upper component 12 and the lower component 11, the toilet device 1 has a simple configuration and can be reduced in weight.

Since the switching valve 84 is arranged in the water supply tank 3, the toilet device 1 is unlikely to be damaged due to an external force applied to the switching valve 84. Since the switching handle 85 is housed in the handle recess 123, damage due to an external force applied to the switching handle 85 exposed to the outside of the upper component 12 is unlikely to occur.

In the above embodiment, an example including an articulated mechanism is shown as an example of the means for adjusting the orientation of the buttocks cleaning nozzle 5. The bottom cleaning nozzle 5 may have a configuration in which the direction of the water discharge port 51 can be adjusted and the direction of the water discharge port 51 can be maintained in a natural state. As the means for adjusting the orientation of the buttocks cleaning nozzle, for example, a bellows type nozzle capable of maintaining a posture may be adopted.

It is preferable from the viewpoint of hygiene that the toilet lid 14 is in the closed position when the toilet device is not in use. The toilet lid 14 is not an essential configuration.

In the above embodiment, an example including two toilet bowl cleaning nozzles 7 is shown. The number of toilet bowl cleaning nozzles is not limited to this. The toilet bowl cleaning nozzle may be one or a plurality.

In the above embodiment, as the manual pump 6, the check valve having a bag-like structure having flexibility and shape restoration and restricting the water transfer direction to the water supply side is the primary side and the secondary side of the pump. An example of adopting a positive displacement liquid pump mounted on the side is shown. The manual pump has a bag-like structure in which the pump has flexibility and shape restoration, and a check valve that regulates the water transfer direction to the water supply side is mounted on the primary side and the secondary side of the pump. Not limited to liquid pumps. The manual pump may be, for example, an accumulator type liquid pump. The accumulator pump mechanism has a mechanism for pressurizing the gas existing above the washing water in the upper component 12, and is composed of a valve capable of appropriately shutting off each path of the washing water of the toilet bowl and the buttocks. To. Before cleaning, the valve of the pump is closed in advance, and the internal pressure of the gas is raised from the atmospheric pressure by the pressurizing mechanism. After that, when the valve is opened, the cleaning water is pushed out to each cleaning nozzle via each tube by the expansion force of the gas.

Next, the toilet bowl device 1A according to the second embodiment will be described with reference to FIG. 7. In the following description, the same components as those already described will be designated by the same reference numerals, and duplicate description will be omitted. The toilet bowl device 1A according to the present embodiment is an example of a so-called squat type toilet bowl device 1A in which the user puts his / her foot around the toilet bowl 4 and crouches down to use it. The point that the toilet seat 13 and the toilet lid 14 are not provided, and the dimensions are different from those of the first embodiment.

Since the toilet bowl device 1A is a squat type, the overall dimensions are shorter in the vertical direction H than the toilet bowl device 1 according to the first embodiment. The toilet bowl device 1A is a mode in which the toilet bowl device 1A is used by crouching on the upper surface 121A of the toilet bowl device 1A. Therefore, the height in the vertical direction H is low in order to obtain physical stability and a psychological sense of security for the user. Since the user rests his / her feet, the area of the upper surface 121A around the toilet bowl 4 in the upper part 12 is larger than that of the toilet device 1 according to the first embodiment.
