The water tank 84 has a quadrangular tank shape that forms a vertically long flat container, and has an upper surface 84u, a side surface 84s, a rear surface 84r, and a front surface 84f. Since the thickness t1 of the water tank 84 is smaller than the width and height, even if the water tank 84 is mounted on the portable toilet, an increase in the installation space of the portable toilet is prevented. The water tank 84 includes a supply port 85 that is provided in an upper portion of the water tank 84 and supplies water such as tap water, and a detachable lid member 86 that opens and closes the supply port 85. Since the supply port 85 is provided in the upper part of the water tank 84, it is advantageous for water supply work. The height position of the supply port 85 is set lower than the upper surface 48 u of the backrest portion 48 (partition member) and the upper end 47 u of the back plate portion 47. For this reason, when the assistant is supplying water to the replenishment port 85 of the water tank 84, the backrest portion 48 can improve the separation between the user sitting on the seating portion 1 and the water supply work by the assistant. . Moreover, since the backrest part 48 is provided between the seating part 1 and the water tank 84, it is suppressed that a user's back contacts the water tank 84 directly.

  As shown in FIG. 2, the water tank 84 is provided with an indicator 84w indicating the amount of water. As shown in FIG. 2, the support portion 87 formed of a linear body such as a wire is hung on the rear surface 84r of the water tank 84, thereby improving the supportability of the water tank 84. A water supply 88 is provided below the side surface 84 s of the water tank 84. In addition, a holder 84x is provided on the side surface 84s of the water tank 84 to hold the excrement container cleaning unit 8 temporarily.

  As shown in FIG. 2, one end 89a of a water supply hose 89 (flexible pipe) as a flexible water supply pipe is connected to a water supply 88, and the other end 89c of the water supply hose 89 is a waste container. It is connected to the base end of the cleaning unit 8. The water supply hose 89 has a three-dimensional flexibility and a predetermined length. Therefore, the excrement container cleaning unit 8 is movable as much as the length of the water supply hose 89. Even when the excrement container 3 is removed from the base 4, if the excrement container 3 is installed in the vicinity of the base 4, the excrement container cleaning unit 8 is connected to the excrement container 3 by the water supply hose 89. It has come to reach. Therefore, the excrement container 3 can be cleaned with the water discharged from the excrement container washing part 8.

  As shown in FIG. 3, the water tank 84 includes a tank chamber 84a provided on the upper side and capable of containing water, and a control chamber 84c provided on the lower side of the tank chamber 84a. The water capacity of the tank chamber 84a is set so that the waste container 3 cleaning process and the user's local cleaning process can be executed a predetermined number of times.

As shown in FIG. 3, the control chamber 84c supplies water to the excrement container cleaning unit 8 provided in the first water supply path 91 and the second water supply path 92, which are connected to the tank chamber 84a independently of each other, and the first water supply path 91. The first water supply means 93 that can be provided, the second water supply means 96 that is provided in the second water supply path 92 and can supply water to the local cleaning unit 20 (20f, 20s), and a controller 99 are provided. The controller 99 controls the first water supply means 93 via the first signal line 93s and also controls the second water supply means 96 via the second signal line 96s. The first water supply means 93 includes a first electric pump 94 (first pump) having a water supply function and a first motor 95 that drives the first electric pump 94. The second water supply means 96 includes a second electric pump 97 (second pump) having a water supply function, and a second motor 98 that drives the second electric pump 97. A commercial power supply (AC 100 volts) is connected to the controller 99 via an adapter 90.

  The first electric pump 94 of the first water supply means 93 and the second electric pump 97 of the second water supply means 96 are driven independently of each other. Therefore, even if the first electric pump 94 is stopped due to a failure or the like, the second electric pump 97 can be driven. Even if the second electric pump 97 stops due to a failure or the like, the first electric pump 94 can be driven.

  As described above, according to this embodiment, the first electric pump 94 of the first water supply means 93 and the second electric pump 97 of the second water supply means 96 are set to be driven independently of each other. For this reason, the water pressure supplied to the excrement container cleaning unit 8 and the water pressure supplied to the local cleaning unit 20 (20f, 20s) may be the same or different values, increasing the degree of freedom of water pressure setting. be able to. The amount of water per unit time supplied to the excrement container cleaning unit 8 and the amount of water per unit time supplied to the local cleaning unit 20 (20f, 20s) may be the same or different values. The degree of freedom in setting the amount of water can be increased. In other words, the water pressure P1 for supplying water to the excrement container cleaning unit 8 and the water pressure P2 for supplying water to the local cleaning unit 20 (20f, 20s) are required for the cleaning power required for cleaning the excrement container 3 and the local cleaning. It can be set individually according to the cleaning power and the like. Note that P1 = P2 or P1≈P2, P1> P2, or P1 <P2. Further, the amount of water V1 per unit time supplied to the excrement container cleaning unit 8 and the amount of water V2 per unit time supplied to the local cleaning unit 20 (20f, 20s) are required for cleaning the excrement container 3. It can be set individually according to the power and the cleaning power required for local cleaning. Note that V1 = V2 or V1≈V2, V1> V2, or V1 <V2.

  In consideration of cost reduction, the first electric pump 94 of the first water supply means 93 and the second electric pump 97 of the second water supply means 96 can be of the same type.

  A water level detection means 84e is provided in the tank chamber 84a. The water level signal from the water level detection means 84e is input to the controller 99 via the signal line 84f. The water in the water tank 84 is shared by both the local cleaning unit 20 and the excrement container cleaning unit 8. When the water level in the tank chamber 84a is excessively reduced, the controller 99 stops the first water supply means 93 and the second water supply means 96, and notifies that effect by a notification means such as a display LED.

  The second water supply path 92 is a water supply passage that connects the tank chamber 84 a of the water tank 84 and the local cleaning unit 20 (20 f, 20 s), and is built in the local cleaning device 2. An electric heater 25 for heating the water in the second water supply path 92 is incorporated in the local cleaning device 2. According to the present embodiment, since the water supplied to the local cleaning unit 20 (20f, 20s) can be heated by the heater 25, the user's local part can be cleaned with warm water. For this reason, the discomfort at the time of local cleaning is not generated. On the other hand, although the 1st water supply path 91 is connected with the excrement container washing | cleaning part 8, since the water of the 1st water supply path 91 does not touch a user's local part directly, the request | requirement which heats water is required. There are few heaters. Therefore, the temperature of the water supplied to the excrement container cleaning unit 8 is basically the water temperature of the tank chamber 84a. For this reason, it can contribute to reduction of electrical energy.

  FIG. 4 shows a plan view of the slide member 7 according to this embodiment. As shown in FIG. 4, the slide member 7 has a frame shape, and includes a drawer operation portion 70 formed on the front side and a frame portion 72 having an opening 72 m for accommodating the outer bucket 5. On the upper surface of the frame portion 72 of the slide member 7, a mounting surface 73 on which the flange portion 52 of the outer bucket 5 can be mounted is formed. Accordingly, the flange portion 52 of the outer bucket 5 can be placed on the placement surface 73 on the upper surface of the frame portion 72 of the slide member 7. FIG. 5 shows a state in which the flange portion 52 of the outer bucket 5 is placed on the mounting surface 73 on the upper surface of the frame portion 72 of the slide member 7 while the outer bucket 5 is fitted into the opening 72 m of the slide member 7.

  According to this embodiment, when the user is seated on the seat portion 1, the load seated on the seat portion 1 is transmitted to the flange portion 52 of the outer bucket 5 via the seat portion 1. Here, the slide member 7 is not a divided part divided forward and backward, but is a single part. For this reason, since the whole flange part 52 of the outer bucket 5 is mounted on the mounting surface 53 of the slide member 7 which is a single component, the load supportability can be enhanced.

  The drawer operation unit 70 of the slide member 7 can be drawn forward (in the direction of arrow F) with respect to the fixed frame 40 of the base body 4. If the pull-out operation portion 70 of the slide member 7 is pulled forward (in the direction of arrow F), the slide member 7 can be pulled out from the fixed frame 40 of the base body 4, and therefore the outer bucket 5 held by the slide member 7 is also included. The excrement container 3 that is pulled forward (arrow F direction) and accommodated in the outer bucket 5 is also pulled forward (arrow F direction).

  According to the conventional portable toilet having no local cleaning function, the local cleaning device 2 is not provided on the base 4. For this reason, according to the conventional portable toilet, there is no interference between the rear part 3r of the excrement container 3 and the local cleaning unit 20, and therefore the excrement container 3 is placed on the base 4 while the seating part 1 is swung upward. The excrement container 3 can be removed from the fixed frame 40 by lifting it upward as it is.

  However, according to the portable toilet of the type having a local cleaning function, the local cleaning device 2 is provided on the base 4, and the water outlet at the tip of the nozzle type local cleaning unit 20 is the excrement of the excrement container 3. It is often arranged so as to face the storage chamber 31. Furthermore, since the excrement storage chamber 3 needs to receive the water discharged from the water discharge port at the tip of the local cleaning unit 20, the rear part 3 r of the excrement storage chamber 3 is located behind the local cleaning unit 20. become. In this case, if the excrement container 3 is lifted as it is with the seating part 1 being swung upward, the rear part 3r of the excrement container 3 interferes with the local cleaning part 20 of the local cleaning device 2 ( (See FIG. 5).

  Therefore, according to the present embodiment, the flange portion 52 of the outer bucket 5 is placed on the mounting surface 73 of the slide member 7 slidable forward (in the direction of arrow F), and the excrement container 3 is accommodated in the outer bucket 5. This method is adopted. Then, when the excrement in the excrement container 3 is discarded, as shown in FIG. 6, an assistant or the like is provided with the pulling operation unit 70 of the slide member 7 on which the flange portion 52 of the outer bucket 5 that accommodates the excrement container 3 is placed. Is slightly slid (ΔS) toward the front (arrow F direction). With this slide, as shown in FIG. 6, the rear part 5 r of the outer bucket 5 and the rear part 3 r of the excrement container 3 move forward (in the direction of arrow F), and the rear part 3 r of the excrement container 3 and the local cleaning device 2 Interference with the local cleaning unit 20 is avoided. Furthermore, interference between the rear portion 5r of the outer bucket 5 and the local cleaning unit 20 of the local cleaning device 2 is avoided.

  If an assistant or the like lifts the excrement container 3 upward (in the direction of the arrow Y1) while avoiding interference as described above, the rear part 3r of the excrement container 3 and the local cleaning unit 20 do not interfere with each other. The excrement container 3 can be lifted and removed from the outer bucket 5. And the excrement W collected in the excrement container 3 made to detach | leave can be discarded, and it is convenient for the cleaning process of the excrement container 3. FIG. Further, if the outer bucket 5 is lifted upward (in the direction of the arrow Y1) while avoiding interference as described above, the outer bucket 5 can be removed without causing the local cleaning unit 20 and the rear portion 5r of the outer bucket 5 to interfere with each other. The substrate 4 can be lifted and removed from the container housing chamber 42. Therefore, the cleaning process of the outer bucket 5 is also convenient.

  By the way, when the slide member 7 is pulled forward, the slide member 7 is moved forward until the whole excrement container 3 and the outer bucket 5 supported by the slide member 7 are completely detached from the fixed frame 40 of the base body 4. A moving method is also conceivable. However, in this case, due to the long distance to slide the excrement container 3 forward, the water surface WA of the sewage stored in the excrement storage chamber 31 of the excrement container 3 swings with the slide, There is a possibility that sewage may scatter around the excrement container 3, which is not preferable. In this respect, according to the present embodiment, the slide member 7 does not have to be moved forward until the whole excrement container 3 and the outer bucket 5 supported by the slide member 7 are detached from the fixed frame 40 of the base body 4. That is, as described above, the slide (slide amount ΔS) of the slide member 7 can avoid interference between the rear part 3r of the excrement container 3 and the local cleaning unit 20 of the local cleaning device 2, and the rear part 5r of the outer bucket 5 And interference with the local cleaning unit 20 of the local cleaning device 2 can be avoided. A method of lifting the excrement container 3 upward or lifting the outer bucket 5 upward while avoiding interference as described above is employed. Therefore, the distance (ΔS) for sliding the slide member 7 on which the waste container 3 is placed is small, and the water surface WA of the sewage in the waste storage chamber 31 of the waste container 3 supported by the slide member 7 is fluctuated. Movement can be suppressed and scattering of sewage can be suppressed.

  A general cleaning method for the portable toilet according to the present embodiment will be described. First, in a state where the opening 30 of the excrement container 3 is exposed, as shown in FIG. 7, the rod-shaped excrement container cleaning unit 8 is inserted while facing the excrement storage chamber 31 of the excrement container 3. And the switch 80 of the excrement container washing | cleaning part 8 is operated, and the 1st water supply means 93 is driven. As a result, the first electric pump 94 supplies water to the excrement container cleaning unit 8, and water is discharged from the nozzle portion 8 k of the excrement container cleaning unit 8. Thus, the inside of the excrement container 3 can be washed with the water discharged from the nozzle part 8k of the excrement container washing part 8, and the excrement container 3 can be sanitized.

  When it is desired to clean the outer bucket 5, the outer bucket 5 is exposed. In this state, the rod-shaped excrement container washing unit 8 is inserted into the storage chamber 51 of the outer bucket 5, and the inside of the outer bucket 5 is washed with water ejected from the excrement container washing unit 8. Since the water supply hose 89 has flexibility, the position and orientation of the excrement container washing unit 8 can be arbitrarily changed, which is convenient for cleaning the excrement container 3 and the outer bucket 5. When it is desired to store water in the excrement container 3, water may be discharged into the excrement container 3 from the nozzle portion 8 k of the excrement container cleaning unit 8. In addition, since the water discharged from the nozzle part 8k of the excrement container washing | cleaning part 8 is not heated with the heater 25 unlike the case of local washing | cleaning, it is generally normal temperature water.

  Further explanation will be added. As shown in FIG. 8, when the container lid 36 is attached to the excrement container 3, the rear part 36 r of the container lid 36 of the excrement container 3 and the local cleaning unit 20 (20 f, 20 s) of the local cleaning device 2 Interfere with each other, and the container lid 36 cannot be lifted upward, and the container lid 36 cannot be removed. Therefore, as described above, as shown in FIG. 9, the slide member 7 on which the excretory container 3 with the container lid 36 attached is set in a state where the seating portion 1 is swung upward to the retracted position. Is slightly slid forward (in the direction of arrow F) (sliding amount = ΔS), the interference between the rear portion 36r of the container lid 36 of the excrement container 3 and the local cleaning unit 20 of the local cleaning device 2 is immediately avoided ( (See FIG. 9). Therefore, the container lid 36 can be lifted upward and removed from the excrement container 3 as shown in FIG. And the excrement container washing | cleaning part 8 is inserted in the excrement container 3 in the state which removed the container cover 36, and the excrement container 3 can be wash | cleaned with the water discharged from the excrement container washing | cleaning part 8. FIG. If necessary, the excrement container 3 can be lifted and removed from the storage chamber 51 of the outer bucket 5 as shown in FIG.

  According to the present embodiment, as shown in FIG. 2, the water tank 84 is provided behind the backrest portion 48 of the rear portion 4 r of the base body 4, that is, on the back side of the user sitting on the seating portion 1. Further, the height position of the upper surface 48 u of the backrest 48 is set higher than the height position of the supply port 85. For this reason, the assistant or the like is seated on the seating portion 1 while the assistant or the like is supplying water to the supply port 85 of the water tank 4 using a water storage container such as a kettle or a water hose or the like behind the backrest portion 48. Even if the user moves, the user's body is prevented from hitting a water storage container such as a kettle or a water hose, and the water supply work to the supply port 85 of the water tank 84 is prevented from being impaired. Therefore, the backrest part 48 has a function as a partition member for partitioning the seating space and the tank space in addition to having a backrest function for a user seated on the seating part 1.

The drawer operation portion 70 and the front plate portion 44 formed at the front end portion of the slide member 7 face the leg portions of the user who sits on the seat portion 1. In this case, in the plan view shown in FIG. 4A, in the drawer operation portion 70 of the slide member 7, the center portion 70c in the width direction protrudes forward (arrow F direction) from both end portions 70e in the width direction. In other words, in the pull-out operation portion 70 of the slide member 7, both end portions 70 e in the width direction are retracted backward (in the direction of arrow R) rather than the central portion 70 c in the width direction.

  The same applies to the front plate portion 44 (a part of the base body 4) that overlaps the drawer operation portion 70 of the slide member 7. That is, as shown in FIG. 7, at the front surface 44f of the front plate portion 44, the center portion 44c in the width direction protrudes forward (in the direction of arrow F) from both end portions 44e in the width direction. In other words, at the front surface 44f of the front plate portion 44, both end portions 44e in the width direction are retracted toward the rear in the front-rear direction (arrow R direction) of the portable toilet rather than the central portion 44c in the width direction. For this reason, as a comparative example, the front surface of the slide member drawer operation portion and the front surface of the front plate portion are set to a virtual line WA (see FIG. 4A) along the width direction (arrow W direction). In comparison, a space S100 is secured behind the virtual line WA. Therefore, when the user is seated on the seating portion 1, it is easy to secure a space for the user's legs (left leg portion, right leg portion), and the user can easily sit on the seating portion 1. Suitable for use by the elderly and disabled. This is because the center portion in the width direction of the seat portion 1 that is a toilet seat protrudes from both end portions in the width direction.
