Description

The present invention relates to a manual butt-washing washer and a toilet bowl comprising the manual butt-washing washer and a toilet bowl including the manual butt-washing washer, which is particularly suitable for use in a toilet or a portable toilet bowl attached to an unmanned facility.

Portable toilets are available for wheelchair users such as the sick and injured, the elderly, and those who cannot easily get out of bed. The portable toilet is provided so that it can be placed near the bed or on the seating surface of a wheelchair in consideration of going out with a wheelchair. Even such a portable toilet is required to have a butt washing function, which has been remarkably popular in recent years. On the other hand, in the existing toilets, it is being promoted to install an electric butt washing device when a manager is resident, but it is installed in an unmanned station, a square or a park of a town association, for example, where there is no manager. Although there is a water washing device in the toilet, the buttocks washing function is not provided due to the difficulty of management. It is described in Patent Documents 1 and 2 that the buttock cleaning mechanism is provided in an existing toilet bowl that does not have such a buttock cleaning mechanism.

The buttock washer described in Patent Document 1 is a buttock washer that cleans the buttocks after defecation and does not use electricity at all, and connects a fountain port that ejects wash water toward the anus to a flexible water pipe. And the flexible water supply pipe is connected to the water pipe via the valve means. Then, the fountain port is directed to the anus or retracted by operating the lever.

The simple butt washing device described in Patent Document 2 is for giving a butt washing function to a toilet bowl that does not have a butt washing device. A cup is used to draw water flowing into the toilet bowl, and the collected water is passed through a hose. , Equipped with an instrument that has the function of ejecting water from the nozzle by the power of the foot pedal. By attaching this device to the toilet bowl with a fixture, it is possible to have a butt washing function without replacing the entire toilet seat.

Patent Document 3 describes an example of a toilet bowl having a manually operated buttock washing function, which does not have a mechanism for heating the washing water when it is not necessary to use hot water. In the human body local cleaning device described in this publication, simply by rotating and moving the rotary dial in the front-rear direction, cleaning water is ejected from the injection port at the tip of the cleaning nozzle along different ejection directions, and the cleaning position or the ass cleaning position or Cleaning water is sprayed to the bidet cleaning position. Furthermore, since the water supply control box and the water supply control valve are integrated, the position of the cleaning nozzle and the amount of water can be controlled simply by rotating or moving the rotary dial back and forth. It should be noted that Patent Document 4 discloses that when a similar nozzle is controlled by using electrical control, the nozzle position and the nozzle direction are controlled by a joystick.

Further, the cleaning nozzle unit is movable in the front-rear direction with respect to the base member and is rotatable. In the cleaning device described in this publication, the nozzle is driven by a spring to move in the front-rear direction. Therefore, in the initial state, the nozzle retracts from the bowl portion due to the spring force, and only when the nozzle is used, the nozzle is manually resisted against the spring force. Since the nozzle is moved into the bowl, the user does not need to be aware that the nozzle is retracted to prevent the nozzle from becoming dirty. However, since the spring force is used, the manual operation force becomes large, and the increase in the number of parts may complicate the device and increase the size of the upper cover. Further, since the cleaning device described in Patent Document 4 uses electrical control, it is applied to a toilet in a place where an administrator is always absent or a portable toilet provided in a wheelchair or the like for the above reason.

Hereinafter, examples of the manual tail cleaning washer (hereinafter also referred to as a washer) 200 will be described with reference to the drawings. FIG. 1 is a perspective view showing an example in which the manual butt washing washer 200 according to the present invention is applied to the portable toilet 100 (FIG. 1 (a)) and the existing toilet bowl 110 (FIG. 1 (b)). The portable toilet 100 is configured in 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 allowing the user to sit, and a bowl 10 for temporarily storing the user's excrement, which also serves as a seat for the user. A toilet bowl body 20, a water supply unit 30 that can be fixed to the toilet bowl body 20, and a washer 200 shown by a broken line in FIG. 1 are provided. The pedestal portion (toilet bowl body) 20 has 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 that supports from the back when the user sits down. 24 is provided in the peripheral portion, and a storage portion 26 for detachably accommodating the bowl 10 is provided in the lower portion. The accommodating portion 26 includes the bowl 10. The washer 200 is disposed inside the back wall 24.

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 spherical grip 222 is attached to the upper end of the lever 220. The lower end of the lever 220 is connected to a drive shaft 250 whose details will be described later, so that a through hole 23a is formed in the right side wall 23 of the toilet body 20. The drive shaft 250 and the lever 220 constitute the washer 200. Although the lever 220 is arranged on the right side in FIG. 1A, it is also possible to arrange the lever 220 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 entry / exit of the 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 space on the back side of the toilet bowl main body 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 nozzle 210 moves in and out of the bowl 10, a space for storing and holding the 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 portability is impaired. Therefore, the movable range of the washer 200 in the front-rear direction is made as small as possible, and the washer 200 is made to be a linear motion type to avoid complication of the mechanism.

The amount of water or hot water supplied to the nozzle 210 was set to an amount that almost fills a PET bottle containing 2 liters in consideration of the feature of the portable toilet 100. The nozzle 210 requires a head in which the PET bottle container is turned upside down and its outlet (cap portion) is raised by 40 to 50 cm or more from the position of the nozzle 210 or the entry / exit hole 12.

In this embodiment, water or hot water is supplied by using a fixture 38 which is on the left rear side of the portable toilet 100 and has one end fixed to the toilet body 20 and an annular receiver 39 connected to the fixture 38.

FIG. 5D shows a state in which the lever 220 is opened, and the drive shaft 250 is moved to the rightmost side in FIGS. 1 to 3. The arrow in the figure indicates the opening / closing direction of the lever 220.

A stopper 280 is attached to one side of the support plate 232 that supports the drive shaft 250, usually on the outer surface side of the support plate 232 on the right side. The stopper 280 is configured such that a cover portion 282 is integrally provided by a semicircular portion on a disk portion 281 provided at the center of a hole through which the drive shaft 250 penetrates. When the lever 220 is closed with the stopper 280 attached, the stopper portion 260 of the lever 220 abuts on the inner wall of the cover portion 282 at the contact portion 261 on the back surface side (pull-in side) thereof. At this time, the front surface side of the stopper portion 260 is not in contact with the disk portion 281.

When the lever 220 is opened from this state, the lever 220 rotates about the connecting hole 256 and comes into contact with the upper surface of the disk portion 281 at the contact portion 263 on the front side (extension side) of the stopper portion 260 of the lever 220. Further rotation is prevented. In addition, in order to prevent the stopper portion of the lever 220 from coming off downward after the rotation of the lever 220 progresses and the contact portion 263 abuts, the abutting portion 265 that abuts on the drive shaft 250 is brought into contact with the lever 220. It may be provided as a detent.

The rotation of the lever 220 will be described with reference to FIG. 5 (e). The rotation of the lever 220 around the drive shaft 250 is restricted by the mounting groove 258 formed in the drive shaft 250. Therefore, the lever 220 rotates together with the drive shaft 250. In other words, the operation of the lever 220 around the drive shaft 250 indicated by the arrow in the figure is an operation of directly rotating the drive shaft 250.

Next, the conversion of the motion of the drive shaft 250 to the linear motion of the nozzle 210 and the opening and closing of the valve 240 will be described with reference to FIG. FIG. 6 is a diagram showing details of a link mechanism that directly moves the nozzle 210, and is a side view showing a portion of the valve 240 between the valve shaft 249 and the nozzle 210. 6 (a) is a diagram showing a general state in which the position of the nozzle 210 is not specified, FIG. 6 (b) is a diagram showing a state in which the nozzle 210 is most retracted, and FIG. 6 (c) is a diagram. It is a figure which shows the state which extended the nozzle 210 most. The arrows in FIGS. 6 (b) and 6 (c) indicate the movable direction of the nozzle 210. In these figures, the axis of the valve shaft 249 and the axis of the drive shaft 250 are always movable regardless of the motion state of the drive shaft 250 and the nozzle 210, although the drive shaft 250 can move in the direction perpendicular to the paper surface. It is an immovable point in a fixed position. Further, since the linear motion support means 238 is fixed to the base plate 230, it is also immovable. However, since the linear motion support means 238 is made of resin, it can be elastically deformed slightly according to the movement of the nozzle 210.

As described above, the first link plate 276 is fixedly attached to the valve shaft 249 of the valve 240, and the second link plate 274 is attached to the first link plate 276 at the node 302 with respect to each other. It is rotatably attached. The second link plate 274 is rotatably attached to the third link plate 252 at the node 304 with respect to each other. As a result, a known four-node link having a stationary node between the axis of the valve shaft 249 and the axis of the drive shaft 250 is formed.

In the four-section link of the present invention, the third link plate 252 serves as a driving node, and the first link plate 276 which is a subordinate node is driven via the second link plate 274 which is an intermediate node. That is, the rotational movement of the drive shaft 250 becomes the driving force of the third link plate 252, and becomes the rotation of the first link plate 276 and eventually the valve shaft 249. By this four-node link mechanism, the valve 240 opens and closes by rotating the shaft in the valve shaft portion 241 in synchronization with the rotation of the drive shaft 250.

On the other hand, in the elongated hole 254 formed in the vicinity of the shaft end portion of the third link plate 252, the fifth link plate 214 having one end fixed to the nozzle 210 by welding floats via the fourth link member 216. It is installed as possible. Therefore, the nozzle 210 constitutes a part of the slider crank mechanism that linearly moves (slides) the linear motion support means 238 via the fourth link member 216. As a result, the rotation of the drive shaft 250 around the axis caused by the lever 220 is converted into the sliding motion of the nozzle 210 in the linear motion support means (corresponding to the slider) 238 using the third link plate 252 as the crank. Ru.

Next, the conversion from the linear motion of the drive shaft 250 to the rotation of the nozzle 210 will be described with reference to FIG. 7. FIG. 7 is a front schematic view of the nozzle 210 portion for explaining the operation of the rotating link plate 214 attached to the nozzle 210. FIG. 7 (a) shows a state in which the bottom cleaning hole 212 at the tip of the nozzle 210 is in a neutral position facing almost directly upward, and FIG. 7 (b) shows the bottom cleaning hole 212 laterally (on the left side in the figure). Indicates that it is in a facing state.

When the lever 220 is opened and closed to move the drive shaft 250 linearly in the longitudinal direction thereof, the rotating link plate 214 fixedly attached to the upper surface of the nozzle 210 in the neutral position does not bend left or right and is along the vertical direction. The nozzle 210 is tilted forward by the amount of tilt. At this time, the direction of the bottom cleaning hole 212 is also in a state of being tilted forward along the vertical direction. When the lever 220 is opened from the neutral position and the drive shaft 250 is pushed to the left side in FIG. 2, the pair of third link plates 252 and 252 and the fourth link member 216 sandwiched between these link plates 252 and 252 are released. It moves to the left with the drive shaft 250. At this time, since the tip of the nozzle 210 is held by the linear motion support means 238, the nozzle 210 cannot move in the left-right direction. Therefore, the rotating link plate 214 connected to the fourth link member 216 at the node 306 rotates around the node 306. Since the rotating link plate 214 rotates around the node 306, the nozzle 210 to which the rotating link plate 214 is fixed also rotates. That is, despite the linear motion of the drive shaft 250, the link member 216 rotates around the axis of the nozzle 210 while staying in place without changing the position of the drive shaft 250 in the longitudinal direction. As a result, the tail cleaning hole 212 formed at the tip of the nozzle 210 is turned to a desired direction. As described above, when the nozzle 210 operates, the connecting shaft 272 attached to the third link plate 252 also moves left and right, so that the node of the second link plate 274 is in the longitudinal direction of the drive shaft 250. Is movably connected to the connecting shaft 272.

Other examples of the bottom washing washer according to the present invention will be described with reference to FIGS. 8 to 10. In this embodiment, the bottom cleaning washer 200 shown in the above embodiment is provided with a second valve device 330. This is for particularly cleaning the nozzle 210 included in the bottom cleaning washer 200b. The figure shows an example in which the water used for cleaning the bottom is also used for cleaning the nozzle 210, but a cleaning liquid tank specialized for cleaning the nozzle 210 is separately provided, and the cleaning liquid in the tank is used for cleaning the nozzle 210. You can also do it.

FIG. 8 is a top view of the bottom cleaning washer 200b including the second valve device 330, which corresponds to FIG. As described above, in the butt washing washer 200b shown in FIG. 8, a second valve device 330 is added to the butt washing washer 200 shown in FIG. Therefore, the cleaning liquid piping system includes connecting hoses 42a and 42c that lead from a water container 32 such as a PET bottle to the valve 240 via the tee 326, and a connecting hose 42b that connects the other port of the tee 326 to the second valve 340. It also has connecting hoses 42f and 42e that connect the second valve 340 and the nozzle 210 via the tee 328, and connecting hoses 42d that connect the other mouth of the tee 328 to the valve 240. This makes it possible to switch the cleaning liquid contained in the water container 32 via the valve 240 or the second valve 340 according to the switching between the valve 240 and the second valve 340 and allow the cleaning liquid to flow from the tip of the nozzle 210. Become.

The second valve 340 is arranged in the vicinity of one auxiliary support plate 236 and is held by the valve mounting portion 322b via a screw portion formed on the valve mounting portion 322b of the fastener 320 formed in an L shape. (See FIG. 9). The bottom of the second valve 340 can be brought into contact with the pusher 372 attached to the drive shaft 250, as will be described in detail later. As one of the characteristic configurations of this embodiment, a nozzle cleaning tool 208 for cleaning the nozzle 210 itself is provided near the bottom cleaning hole 212 at the tip of the nozzle 210.

The operation of the second valve 340 will be described with reference to FIG. 9 is a diagram for explaining the operation of the second valve device 330, and FIG. 9A is a partial vertical sectional view showing a state of the second valve device 330 during operation, FIG. 9B. Is a partial vertical sectional view showing a normal state when the second valve device 330 is not operating. That is, the second valve 340 is normally closed. The second valve 340 is configured as, for example, a mechanical valve in which a resin piston 356 directly moves inside a cylinder-shaped housing 352. A joint portion 322 as an inflow port for cleaning liquid, water in this embodiment, and a joint portion 324 as an outflow port for fluid to flow out are provided on the longitudinal side portion of the housing 352. The piston 356 is connected to the shafts 354a and 354b, and a stopper 358 is provided between the shafts 354a and 354b.

When the movable portion having the piston 356 is formed in this way, when the piston 356 is located below and the stopper 358 comes into contact with the bottom surface of the internal space of the housing 352 (state of FIG. 9B), the housing 352 Inside, a space 382 is formed above the piston 356, and a space 384 is formed between the piston 356 and the stopper 358. Although the space 384 communicates with the outlet side joint portion 324, the opening thereof is blocked by the piston 356 and does not communicate with the inlet side joint portion 322. As a result, the second valve 340 is put into a non-operating state. On the other hand, when the piston 356 comes into contact with the uppermost surface of the space inside the housing 352 (state in FIG. 9A), a space 386 is formed below the stopper 358, and a space between the piston 356 and the stopper 358 is formed. It moves upward and communicates with both the inlet side joint portion 322 and the outlet side joint portion 324. As a result, the second valve 340 is put into operation.

The shaft 354b extends to the outside of the housing 352 so that the piston 356 moves up and down in this way. A disk-shaped receiver 364 is attached to the tip extending to the outside of the shaft 354b. A spring 362 is wound around the shaft 354b between the receiver 364 and the bottom of the housing 352. The lower surface of the receiver 364 is countersunk to form a recess 366. A seal 360 is provided between the shaft 354b and the lower part of the housing 352 to prevent leakage of the cleaning liquid.

On the other hand, in the portion of the drive shaft 250 near the second valve 340, a plate-shaped pusher 372 extends substantially from the center line (diameter line) of the drive shaft 250 and is fixedly arranged. For example, a semicircular spherical contact portion 374 is formed at the tip portion of the 372. Therefore, the pusher 372 can rotate together with the drive shaft 250. The pusher 372, the drive shaft 250 and the second valve 340 form a second valve device 330. Instead of the concave portion 366 of the contact portion 374 and the receiver 364, a hemispherical contact portion may be provided on the receiver 364 side, and the pusher 372 may be a flat plate. The structure is simpler than in this case. It is not always necessary to provide a hemispherical abutment on either the pusher 372 or the receiver 364, but such abutment facilitates the smooth operation of the second valve 340. To.

In the second valve device 330 configured in this way, for example, when the drive shaft 250 rotates so that the pusher 372 is in the horizontal position, the contact portion 374 substantially abuts on the recess 366. In this state, the stopper 358 remains in contact with the bottom surface of the internal space of the housing 352. When the drive shaft 250 is rotated clockwise in FIG. 9 from this, the contact portion 374 moves upward against the urging force of the spring 362 and pushes up the piston 356. As a result, the inlet side joint portion 322 and the outlet side joint portion 324 communicate with each other, and the second valve is put into an operating state.

In the second valve 340 in the operating state, when the drive shaft 250 is rotated counterclockwise in FIG. 9 so as to return the pusher 372 to the horizontal direction, the piston 356 is lowered by the urging force of the spring 362, and the inlet side joint portion is gradually lowered. When the opening area of the 322 is reduced and the pusher 372 becomes almost horizontal, the piston 356 completely closes the opening of the inlet side joint portion 322. When the drive shaft 250 is further rotated counterclockwise from this state, the recess 366 formed in the receiver 364 and the contact portion 374 are disengaged, and the pusher 372 simply rotates together with the drive shaft 250. That is, when the stopper 358 comes into contact with the inner bottom surface of the housing 352, the piston 356 can be stopped from descending. After that, the piston 356 keeps this state within the rotatable range of the drive shaft 250. The rotation angle range of the drive shaft 250 in which the piston 356 does not move within the housing 352 forms a dead zone angle θ. By providing the dead zone, good interlocking with the movement of the lever 220 and the nozzle 210 connected to the drive shaft 250 becomes possible. This situation will be described with reference to FIG.

FIG. 10 is a diagram showing the moving state of the nozzle 210 in relation to the open / closed state of the second valve 340 and the rotating state of the lever 220, and FIG. 10A is a diagram in which the nozzle 210 is inside the linear motion support means 238. It is a figure which shows the state which it is in the predetermined position, and the figure (b) is the state which the nozzle 210 is pulled into the linear motion support means 238 by a predetermined length or more, and the state which cleans a nozzle 210 is shown. Shows. FIG. 3C shows a case where the nozzle 210 is located in a normal bottom cleaning state, and the tip of the nozzle 210 extends outward by a considerable length from the linear motion support means 238. In FIG. 10, the upper stage is a diagram showing the position of the nozzle 210, the middle stage is a diagram showing the state of the second valve device 330, and the lower stage is a diagram showing the rotational state of the lever 220. In FIG. 10, the horizontal position of the lever 220 is the non-operating position of the nozzle 210, and this position is the neutral position or the initial setting position (default position).

In the state of FIG. 10A, which is the neutral position, the lever 220 is in the horizontal position, and at this time, the tip end portion of the nozzle 210 is substantially in the surface position of the linear motion support means 238. In this state, since the second valve 340 is in the non-operating state, the inlet side joint portion 322 and the outlet side joint portion 324 of the second valve 340 do not communicate with each other. Although not shown, the valve 240 is also set to non-operation at this time, so that the cleaning liquid does not flow out from the nozzle 210.

From this state, when the lever 220 is rotated upward so as to pull the nozzle 210 into the linear motion support means 238 by a predetermined distance or more (state (b)), the second valve 340 operates and the cleaning liquid is supplied to the nozzle 210. Supply. As a result, the cleaning liquid 206b is ejected from the nozzle 210. When the cleaning liquid circulates in the linear motion support means 238, the cleaning liquid flushes away the dirt and the like scraped off by the nozzle cleaning tool 208 arranged close to the bottom cleaning hole 212 of the nozzle 210, so that the cleanliness of the nozzle 210 is improved. Be kept. At this time, since the valve 240 is in a non-operating state as described above, the amount of cleaning liquid used for cleaning the bottom is not used when cleaning the nozzle 210.

When the lever 220 is rotated downward from the neutral state to clean the bottom (state (c)), the second valve is in the dead zone and remains in the non-operating state. On the other hand, since the valve 240 is in the operating state as shown in the first embodiment, the cleaning liquid 206c for cleaning the bottom is sprayed from the tip of the nozzle 210 protruding from the linear motion support means 238. That is, in a series of operations of the buttock cleaning, the lever can be rotated downward to clean the buttock, and then the lever can be pulled back and rotated upward to clean the nozzle. Here, by changing the capacities of the valve 240 and the second valve 340, it is possible to adjust the ratio of the cleaning liquid amount required for tail cleaning and the cleaning liquid amount required for nozzle cleaning, and it is possible to prevent the use of unnecessary cleaning liquid. can. It is also possible to change the cleaning liquid used for bottom cleaning and the cleaning liquid used for nozzle cleaning, which enables more optimum cleaning.

In this embodiment, the second valve 340 is provided separately from the valve 240, but by using the valve 240 as a three-way valve, the second valve 340 can be omitted. In that case, the number of parts decreases.

As described above, according to each of the above embodiments, the nozzle can be moved to an appropriate or desired position of use only by opening / closing and rotating a lever that can be operated by the user himself / herself. Since the drive shaft connected to the lever is simply moved and rotated, the washer can be miniaturized and simplified, and the space occupied by the washer can be reduced.

In addition, since the washer does not require any external power such as electric power, it does not require a motor, etc., and the only operation required is the rotation of the lever, so only a small amount of force is required. It can be used even by a weakened user. In addition, the washer can be easily used even if the toilet bowl is installed in a place where the administrator is absent and there is a concern about the use of electric power other than lighting.
