Hereinafter, some examples of the portable toilet with a washer will be described with reference to the drawings. FIG. 1 is a perspective view of an embodiment of the portable toilet 100 according to the present invention. The portable toilet 100 has a size and weight that can be mounted on a refurbished wheelchair-type cart. However, the portable toilet 100 is configured so that a person who has difficulty walking to the toilet can use it at the bedside.

The portable toilet 100 includes a lid 25 having an egg-shaped opening formed in the center and capable of seating the user, and a bowl 10 for temporarily storing the excrement of the user, which also serves as a seating portion for the user to sit on. A pedestal portion 20, a water supply portion 30 that can be fixed to the pedestal portion 20, and a washer 200 shown by a broken line in FIG. 1 are provided. The pedestal portion 20 surrounds both side walls 22 and 23 having an uppermost portion that serves as an armrest for resting both arms when the user sits on the lid 25, and a back wall 24 that supports from the back when the user sits. A housing unit 26 for detachably accommodating the bowl 10 is provided at the lower portion. The washer 200 is arranged inside the back wall 24. Here, the back wall 24 includes a backrest portion, which is a portion designated by the reference numeral 24 in FIG. 1, and a lower part of the back wall in which the washer 200 shown by the broken line is housed. The washer 200 is arranged inside the lower part of the back wall.

The washer 200 has a lever 220 which is the right end of the washer 200 and extends to the external space of the portable toilet 100. A grip 222, which is spherical in this embodiment, is attached to the upper end of the lever 220. The lower end of the lever 220 is connected to the rotation shaft portion 230, which will be described in detail later, so that a through hole 23a is formed in the right side wall 23 of the pedestal portion 20. The rotating shaft portion 230 and the lever 220 form the washer 200. Although the lever 220 is arranged on the right side in this embodiment, the lever 220 can be arranged on the left side according to the dominant arm of the user. On the upper portions of the side walls 22 and 23, a handle portion 27 for carrying the portable toilet 100 is formed in a rectangular hole shape.

The lid 25 is rotatable around the rear end from a horizontal position to an angle beyond the vertical position, and when a bucket-shaped portable bowl 10 having a vine is housed in the storage part 26 and It is rotated when it is taken out from the accommodating portion 26. In this embodiment, the bowl 10 is a bottomed bowl 10 for temporarily storing filth, but a processing unit may be connected to the bowl 10 to take measures against odor after use. In that case, an opening is formed in the bottom surface of the bowl, and the opening is connected to the treatment section with a hose or the like to transfer the filth to the treatment section, and deodorization treatment or the like is performed with the treatment liquid.

By the way, the washer 200 of the portable toilet 100 according to the present invention is for cleaning the buttocks. The washer 200 has a washer nozzle 210, which will be described in detail later, and has a configuration capable of injecting hot water or water from a tail cleaning hole 212 formed at the tip of the washer nozzle 210. Then, the washer nozzle 210 is arranged near the user's buttocks when washing the buttocks, and is retracted from the bowl 10 so as not to interfere with the operation when the washer nozzle 210 is not used, that is, when excreting. Therefore, in the present embodiment, an entrance / exit hole 12 is formed on the back side of the portable bowl 10 and at the upper portion where the washer nozzle 210 rotatably enters / exits. The entry / exit of the washer nozzle 210 from the entry / exit hole 12 is manually controlled by using the lever 220 via the main portion of the washer 200 arranged in the back side space (lower part of the back wall) of the pedestal portion 20. Therefore, a manual portable toilet 100 that does not require any external power is realized.

In the washer 200 of this embodiment, since the washer nozzle 210 goes in and out of the bowl 10, a space for storing and holding the washer nozzle 210 when it is retracted from the bowl 10 is required behind the bowl 10. When this space becomes large, the shape of the entire portable toilet 100 becomes large, and the portability is impaired. Therefore, it is desired to reduce the size Le (width of the lower part of the back wall) of the movable range of the washer 200 in the front-rear direction as much as possible.

Due to the characteristics of the portable toilet 100, the water or hot water supplied to the washer nozzle 210 has a structure capable of storing a predetermined amount or more of water or hot water so that it can be used even when it is loaded on a cart, for example. This predetermined amount is determined from the injection rate of water or hot water injected from the bottom cleaning hole 212 of the washer nozzle 210, the injection amount per unit time, and the injection duration. From an experimental study by the present inventors, it was sufficient to fill a PET bottle containing 2 liters with a predetermined amount. However, in that case, in order to obtain a predetermined injection speed and flow rate (injection speed and flow rate sufficient for cleaning the bottom), the PET bottle container is turned upside down and its outlet (cap portion) is positioned at the washer nozzle 210 or the entry / exit hole 12. It was found that the head (water head) should be set to be 40 to 50 cm or more higher, that is, 40 to 50 cm or more. At this time, the inner diameter of the pipe through which water or hot water flows needs to be 8 mm or more, more preferably 10 mm or more, and the upper limit of the inner diameter is better if it is not extreme, but if it is 12 mm or less, there is no problem in the experiment. found. It was also found by experiments that the predetermined injection speed and flow rate did not come out when the inner diameter was less than 8 mm.
Further, instead of providing a water tank on the outside like a PET bottle or the like, a water tank can be provided inside the backrest portion of the back wall 24. In that case, the head may be 20 to 30 cm depending on the position of the backrest. In that case, the inner diameter during the flow of water or hot water is preferably 13 mm or more, more preferably 14 mm or more in order to obtain a predetermined injection speed and flow rate. Experiments have shown that the upper limit of the inner diameter is better if it is not extreme, but there is no problem if it is 20 mm or less.

In this embodiment, water or hot water is supplied by using a fixture 38 which is left rear of the portable toilet 100 and has one end fixed to the pedestal portion 20 and an annular receiver 39 connected to the fixture 38. The storable water container 32 is stably held with respect to the portable toilet 100. Any kind of water container 32 can be used, but if the 2 liter PET bottle is turned upside down and reused, it can withstand an external force such as an impact and can be easily obtained, which is convenient.
The flexible connecting hose or tube 42 and the PET bottle 32 are connected by using a connector 36 having a shape corresponding to the cap portion of the PET bottle. An opening 34 for water injection and air bleeding may be formed on the bottom surface of the PET bottle 32. Further, it is preferable that the opening 34 is provided with a lid so that water does not leak even if it is turned upside down.
For water injection and air bleeding, the mouth on the connector 36 side of the PET bottle 32 may be used instead of the opening 34. At that time, it is preferable to connect a hollow pipe from the air vent hole above the water surface in the PET bottle 32 so that water does not leak from the air vent hole formed therein.

Since the PET bottle is reused in the water container 32, even if the jet water is insufficient in outdoor use, the shortage can be easily replenished by using another PET bottle or the like. As described above, in this embodiment, since the water or hot water for cleaning the buttocks is injected from the washer nozzle 210 only by the weight of the water or hot water in the PET bottle, it is easy without the need for other energy sources such as electric power. Can perform buttocks washing after excretion.

Next, the washer 200 will be described in detail with reference to FIGS. 2 and 3. 2A and 2B are views showing the configuration of the washer 200, FIG. 2A is a partial cross-sectional view of the front view thereof, and FIG. 2B is a perspective view of a main part thereof. FIG. 3 is a diagram illustrating a mutual motion state of the lever 220 and the washer nozzle 210 constituting the washer 200, and FIG. 3A is a schematic perspective view showing the relationship between the lever 220 and the washer nozzle 210. b) is a schematic side view showing the relationship between them.

The washer 200 includes a shaft portion 230 extending substantially horizontally, a lever 220 fixedly attached to the right end portion of the shaft portion 230, and a nozzle portion located in the middle portion in the longitudinal direction of the hollow shaft 234 constituting the shaft portion 230. The 208 and the valve portion 250 located in the other longitudinal intermediate portion of the hollow shaft 234 different from the nozzle portion 208 are provided. As described above, the lever 220 is formed with a grip 222 on one end side. On the other hand, the other end side is fixed by a fixture 225 to an auxiliary shaft 226 extending outward from a receiving portion 232 that rotatably supports the shaft 234 on the right side wall 23. Here, the shaft 234 is fixed to the receiving portion 232 by means (not shown). As a result, when the lever 220 is rotated out of the plane of FIG. 2A, the shaft 234 rotates in synchronization with the rotation of the lever 220.

As shown, the shaft 234 extends over the left and right side walls 22, 23. The other end of the shaft 234 is inserted into a receiving portion 22b fixedly attached to the left side wall 22, and the receiving portion 22b rotatably supports the shaft 234 together with the receiving portion 232. By making the receiving portion 22b made of self-lubricating plastic and the receiving portion 232 made of metal, sliding between the receiving portion 232 and the plastic side wall 23 and between the receiving portion 22b and the shaft 234. Lubricity for dynamic motion can be obtained, but instead, a lubricating means such as a lubricant or a quasi-synovial membrane can be applied to these interfaces.

Water or hot water for cleaning the buttocks is supplied to the inside of the hollow shaft 234, but the water or hot water is spaced apart in the axial direction (longitudinal direction) to prevent the water or hot water from spreading into the hollow shaft 234. Two stoppers 238 are arranged. The stopper 238 reduces the dead space in the hollow portion of the shaft 234 so that the limited water supply can be effectively used.

The nozzle portion 208 is a portion that injects water or hot water supplied from the water supply portion 30 via the valve portion 250 to the buttocks of the user, and cleans the buttocks on the outer surface 211 that is the tip and is closest to the buttocks. A washer nozzle 210 having a hole 212 formed therein, a flexible connection hose 214 connected to the washer nozzle 210 via a connector 213, and one end side attached to the shaft 234 by welding or brazing, and the radius of the shaft 234. It is provided with an output pipe 242 extending outward in the direction. A connecting hose 214 is connected to the output pipe 242 via a hose joint 216. At the longitudinal position of the shaft 234 to which the output pipe 242 is attached, a fluid output hole is formed at the inner diameter hole position of the output pipe 242. As a result, the water or hot water that has flowed into the hollow shaft 234 can flow to the washer nozzle 210.

In order to fix and hold the direction of the washer nozzle 210 in the direction perpendicular to the shaft 234, a pair of stays 218 are arranged so as to sandwich the washer nozzle 210 from both sides. That is, one end side of the stay 218 is fixed to the side surface of the washer nozzle 210 by welding, brazing or adhesion along the direction in which the washer nozzle 210 extends, and the other end side is fixed to the outer peripheral surface of the shaft 234 by welding or the like.

The valve portion 250 includes a main body 251 configured on a rectangular parallelepiped, and the main body 251 is formed with a mounting hole 257 through which the shaft 234 penetrates. A radial hole 253 facing in the radial direction when attached to the shaft 234 is formed in the axial (left-right direction) intermediate portion of the main body 251. A connecting hose 42 of the water supply unit 30 is connected to the outer end of the radial hole 253 via a hose joint 43, and water or hot water is supplied into the valve body 251 from the outer side in the radial direction. The main body 251 is rotatably attached to the shaft 234. In order to prevent water or hot water from the water supply unit 30 from leaking from the main body 251, O-rings 255 may be arranged on both sides of the radial hole 253 in the axial direction inside the main body 251. However, in the case of the water pressure used in the present invention, water leakage can be prevented by adjusting the fitting gap of the members without disposing the O-ring 255.

A fluid input hole 252 communicating the hollow portion 236 of the shaft 234 and the radial hole 253 is provided at one location in the circumferential direction of the shaft 234, which is the portion where the radial hole 253 is located when the main body 251 is attached to the shaft 234. It is formed. When the fluid input hole 252 formed in the shaft 234 that rotates the lever 220 and rotates in synchronization with the movement of the lever 220 overlaps the radial hole 253, water or hot water from the water supply unit 30 is discharged to the washer nozzle 210 side. If the two holes 252 and 253 are completely closed, the supply of water or hot water can be cut off.

On the other hand, the lever 220 is not rotated when the washer nozzle 210 is not used, but in such a state, the fluid input hole 252 and the radial hole 253 are at different positions in the circumferential direction, and the end face of the fluid input hole 252 is It is closed by the outer peripheral surface of the shaft 234. As a result, the water or hot water from the water supply unit 30 is prevented from flowing out to the washer nozzle 210 side. In this way, the fluid input hole 252 formed in the shaft 234 acts as a valve that selectively opens and closes the flow path to the washer nozzle 210 according to the rotation angle of the shaft 234.

In order to prevent the main body 251 from rotating around the shaft 234, an L-shaped fixing means 260 composed of a leg portion 260a and a fixing portion 260b is provided on one side surface of the lower portion of the main body 251. It is fixed by the fixture 262. The fixing portion 260b of the fixing means 260 is fixed to the pedestal portion 20 with a fixture 264.

According to this embodiment, as shown in FIGS. 3A and 3B, the lever 220 is moved forward from the default position indicated by the solid line to the position indicated by the dotted line along the side wall 23. When rotated by θ °, the shaft 234 to which the lever 220 is fixed rotates, and the washer nozzle 210 whose direction is fixed with respect to the shaft 234 also rotates around the shaft 234 by θ °. Therefore, the shape of the washer nozzle 210 is formed into an arc shape, preferably a single arc shape, according to the movement thereof. Since the washer nozzle 210 has a rotating structure that makes a circular motion around the shaft 234 in this way, the occupied space occupied by the washer nozzle behind the pedestal portion 20 is significantly reduced as compared with the conventional reciprocating type washer nozzle. be able to. Further, since the washer nozzle 210 is moved in a circular motion, it is possible to easily avoid interference with other parts when retracting the washer nozzle 210.

Since the washer nozzle 210 needs to protrude into the bowl 10 by about 50 mm to 200 mm in order to be used for bottom cleaning, the radius of curvature R of the washer nozzle 210 is also set to about 50 to 200 mm. According to the experimentally obtained result, it was most preferably 75 mm. Further, in consideration of the amount of water supplied from the water supply unit 30 and the comfort during cleaning of the buttock, the hole diameter of the buttock cleaning hole 212 is set to φ2 to 3.5 mm. According to the experimentally obtained results, φ3.5 mm was the optimum.

Next, another embodiment of the present invention will be described with reference to FIGS. 4 to 7. 4A and 4B are views corresponding to FIG. 2, FIG. 4A is a front view showing a part of the washer 200a in cross section, and FIG. 4B is a perspective view of a main part of the washer 200a.

Yes, FIGS. 7 (a) and 7 (c) show the valve portion 360 in the ON state, and FIGS. 7 (b) and 7 (d) show the OFF state.

This embodiment is different from the above embodiment in that the washer nozzle 210 moves in and out of the bowl 10 in the front-rear direction and the tip portion is swung in the bowl 10 in the left-right direction. Even if the user does not sit at the center position of the lid 25 of the seating portion in the left-right direction, by shaking the tip of the washer nozzle 210 left and right, the bottom cleaning hole 212 of the washer nozzle 210 can be placed at an appropriate position. It is possible to position it with respect to the user. Also in this embodiment, the rotation of the lever 220 in the front-rear direction along the side wall 23 coincides with the rotation of the shaft.

As shown in FIG. 4, the end of the lever 320 on the side opposite to the end on which the grip 222 is provided is no longer fixed to the shaft 300, and the shaft 300 is maintained to rotate with the shaft 300. It is configured so that it can rotate freely in the longitudinal direction of. Therefore, the auxiliary shaft 326 interposed in the extension of the shaft 300 is formed with an elongated hole 327 long in the axial direction, and the tip of the lever shaft 321 is rotatably connected to the auxiliary shaft 326 around the shaft 325. doing. As a result, the lever shaft 321 or the lever 320 can rotate along the elongated hole 327. The link member 310 is rotatably attached around the shaft 311 by using a fixture 311 at the intermediate portion in the longitudinal direction of the lever shaft 321. The other end of the link member 310 rotates around the shaft 314 via the fitting 313 to the stay 219 located on the lever 320 side of the stay 219 that fixes the direction of the washer nozzle 210 with respect to the shaft 300. It is installed as possible. In order to extend the link member 310 between the lever 320 and the stay 219, the side wall 23 is formed with a large through hole 23b that does not interfere with the movement of the link member.

One end side (upper end side) of the pair of stays 219 is attached to the washer nozzle 210 as in the embodiment shown in FIG. 2, but the other end side (lower end side) of the stay 219 is directly connected to the shaft 300. Not done. That is, the lower end portions of the pair of support plates 342 are fixedly arranged at the intermediate portion in the longitudinal direction of the shaft 300 with the shaft 300 interposed therebetween. On the other hand, the upper end portions of the pair of support plates 342 are connected to the lower end side of the stay 219 via a holder 217 arranged between the pair of stays 219 facing each other. The pair of support plates 342 and the pair of stays 219 are arranged perpendicular to each other at the connecting portion.

As best seen in FIG. 6, the pair of support plates 342 is connected to a lubricated washer 344, such as PTFE, or a shaft 343 that penetrates the stay 219 via a bush or sliding surface, resulting in The holder 217 is connected to the lower end of the stay 219 to which the holder 217 is attached. With this configuration, the stay 219 can move only with the shaft 300 with respect to the rotation (rotation in the front-rear direction) along the side wall 23 of the shaft 300 to which the lever 320 is attached, that is, the rotation. On the other hand, the shaft 300 cannot be displaced relative to the shaft 300, while the shaft 343 can freely rotate around the center line corresponding to the runout in the left-right direction.

The shaft 325 at the tip of the lever 320, the shaft 312 provided in the middle of the lever shaft 321 and the shaft 314 penetrating the fitting 313 attached to the stay 219, and the shaft 343 of the connecting portion between the support plate 342 and the stay 219 are four. Construct the section of the section link. When the lever 320 is swung in the left-right direction, the four-bar link works to swing the stay 219, and the washer nozzle 210 whose orientation is fixed with respect to the shaft 300 by the stay 219 swings left and right.

This operation will be described with reference to FIG. 5, which schematically shows the washer 200a. When the lever 320 is rotated (also referred to as in-plane rotation) by α from the default position to the front and back (also referred to as in-plane rotation in FIG. 5) along the side wall 23, the washer nozzle 210 is different from the case of FIG. Similarly, it rotates by α in the front-rear direction via the movement of the shaft 300. In this case, the stay 219 and the support plate 342 move as an integral rigid part.

When the user uses the portable toilet 100 and the front-rear position of the washer nozzle 210 becomes an appropriate position, the left-right position of the washer nozzle 210 is determined by shaking the washer nozzle 210 left and right. That is, the lever 320 is rotated in the left-right direction (R direction or L direction in FIG. 5) (also referred to as out-of-plane rotation). The rotation of the lever 320 activates the four-bar link, the link member 310 is pulled to the left and right, the stay 219 rotates with respect to the support plate 342 at the position of the shaft 343, and the stay 219 and the support plate 342 as a whole It becomes a shape that is bent into a <shape or> shape. Assuming that the rotation angle of the lever 320 is β, the rotation angle of the stay 219 is β', which is different from the rotation amount of the lever 320. However, since the rotation of the washer nozzle 210 in the left-right direction is a fine adjustment unlike the rotation in the front-rear direction, there is no sense of discomfort in using it.

In order to return the horizontal rotation of the washer nozzle 210 to the default position, springs 354 having one end fixed to the spring locking portion 355 of the stay 219 are arranged on both sides of the stay 219. The other end of the spring 354 is fixed to the support member 352 attached to the shaft 300. As a result, when the lever 320 is released, the left and right springs 354 are balanced and the washer nozzle 210 is returned to the neutral position of the default position.

Since the washer 200a is provided with a left-right rotation mechanism of the washer nozzle 210, it is difficult to form a valve mechanism using the inside of the shaft. Therefore, instead of passing water or hot water through the shaft, the valve portion 360 is configured in the vicinity of the shaft 300 to prevent the device from becoming large in size. The valve portion 360 utilizes a crank slider type four-bar link, and is a first link composed of a pair of support plates 332, which is an intermediate portion in the longitudinal direction of the shaft 300 and is attached to the lower side of the shaft 300 in FIG. A member 332, a second link member which is a rod-shaped valve body 364 included in the valve portion 360, a fluid input block 362 as a main body through which the valve body 364 is inserted, and a frame body that limits the displacement of the fluid input block 362. It includes a third link member, which is 380. The pair of support plates 332 are connected to the tip end portion of the valve body 364 via a lubricated washer or bush 334, and the valve body 364 is rotatable with respect to the support plate 332. When the shaft 300 rotates, the support plate 332 acts as a crank.

As shown in detail in FIG. 7, the valve portion 360 includes a rod-shaped valve body 364 extending in the axial direction and a main body 362 into which the valve body 364 is inserted. A through hole 398 in which the valve body 364 slides back and forth is formed in the main body 362, and an inflow passage 395 and an outflow passage 397 are formed with the through hole 398 in the direction orthogonal to the through hole 398. ing. A joint mounting portion 366 is formed on the outlet side of the inflow passage 395 and the outflow passage 397, and the hose joint 365 is connected to the joint attachment portion 366. A flexible connection hose 42 included in the water supply unit 30 and a flexible connection hose 214 connected to the washer nozzle 210 are connected to the hose joint 365.

A small diameter portion 394 having a width similar to the outer diameter of the inflow passage 395 and the outflow passage 397 is formed in the intermediate portion in the longitudinal direction of the valve body 364. The portion where the valve body 364 is inserted into the fluid input block 362 and other than the small diameter portion 394 is configured in the large diameter portion 392 having the same diameter. The large-diameter portion 392 and the small-diameter portion 394 of the valve body 364 pass through the portion where the inflow passage 395 and the outflow passage 397 intersect the through hole 398, so that the inflow passage 395 and the outflow passage are in a non-communication and communication state. In order to prevent water or hot water from leaking to the outside during the reciprocating movement of the valve body 364, a plurality of O-rings 396 may be arranged at axial intervals in the through holes 398. However, in the case of the water pressure used in the present invention, water leakage can be prevented by adjusting the fitting gap of the members without arranging the O-ring 396.

As shown in FIGS. 7A and 7C, when the shaft 300 rotates and the small diameter portion 394 of the valve body 364 reaches the inflow passage 395 and the intersection of the outflow passage 397 and the through hole 398, the inflow passage 395 The water or hot water from the water supply unit 30 guided to the above flows out to the outflow passage 397 through the peripheral portion of the small diameter portion 394. The outflow passage 397 communicates with a flow path (not shown) formed in the center of the washer nozzle 210, and water or hot water guided from the water supply unit 30 is discharged from the tail cleaning hole 212 provided at the tip of the flow path. Allows to spout. This is the ON state of the valve portion 360.

On the other hand, as shown in FIGS. 7B and 7D, the shaft 300 rotates and the large diameter portion 392 of the valve body 364 completely closes the inflow passage 395 and the intersection of the outflow passage 397 and the through hole 398. The water or hot water from the water supply unit 30 guided to the inflow passage 395 is dammed by the large diameter portion 392, and the washer nozzle 210 is not supplied with water or hot water. This is the OFF state of the valve portion 360.

Returning to FIG. 4A, in order to restrict the fluid input block 362, which is the main body of the valve portion 360, from freely moving with the rotation of the shaft 300, a frame is placed on the opposite axis 300 side of the fluid input block. Body 380 is connected. Specifically, both frame portions 384 of the frame body 380 formed in a Π shape by both frame portions 384 and fixed portions 386 are connected to the fluid input block 362 using a shaft 370 via a lubricated washer or bush 368. Attach to. As a result, the fluid input block 362 can rotate with respect to the frame body 380. The fixing surface 382 on the back side of the fixing portion 386 facing the valve body 364 is fixed to the pedestal portion 20. Since the frame 380 is fixed to the pedestal 20, the movement of the fluid input block 362 is also restricted. In this way, the crank slider type four-bar link is completed.

Next, a modified example of the lever used in the embodiment shown in FIG. 4 will be described with reference to FIG. The lever 320b of this modification is different from the lever 320 of the embodiment of FIG. 4 in the way of attaching the end of the lever 320b to the auxiliary shaft 326. In this modification, the attachment 324 is attached eccentrically to the end surface of the receiving portion 232a, and the lever shaft 321 is connected to the receiving portion 232a via the attachment 324 by the shaft 323. As a result, if the lever 320b is rotated in-plane, the washer nozzle 210 can be rotated at the same angle as the shaft 300, and if the lever 320b is rotated out-of-plane, the washer nozzle 210 is swung left and right. Can be done. Also in this modification, the washer nozzle 210 can be rotated in two orthogonal directions by a simple method.

According to each of the above embodiments and modifications, the arc-shaped washer nozzle can be moved to an appropriate use position and retracted from the use position simply by rotating the lever that can be operated by the user in-plane. Can be achieved only by the circular motion around the axis. As a result, the size of the washer can be simplified, the space occupied by the washer can be reduced, and even a portable toilet equipped with the washer can be prevented from becoming large.

In addition, the washer does not require any external power such as electric power, and the only movement required is the rotation of the lever, so only a small amount of force is required, and for users with weakened physical strength such as the elderly. It can be used even if it exists. Further, the washer can be easily used even when going out to the outdoors where external power cannot be used. Furthermore, the amount of water used is about the same as that of PET bottles, and in the worst case, drinking water may be purchased from a vending machine and supplied, and there is no need to worry about insufficient water supply.

Further, according to the embodiment of the present invention, the washer nozzle can be rotated in two orthogonal directions, and the washer nozzle can be finely adjusted in the left-right direction without the user of the portable toilet sitting in the center of the portable toilet. It becomes possible to move it to the proper position, and the comfort of using the washer is improved.
