Description

  The present invention relates to a chair-shaped space-saving portable toilet equipped with a cleaning device, and in particular, by disposing a thin water supply tank in a space below the cleaning device, the toilet seat (or By making the lid part) foldable in the folded state downward or behind the backrest, the user can use the seat part (or lid part) of the toilet when using it as a chair or as a toilet. The present invention relates to a space-saving chair-type portable toilet that makes it possible to use the backrest of the toilet body without removing the toilet from the toilet body.

  2. Description of the Related Art Conventionally, portable toilets having a chair-type shape are known so that persons with physical disabilities such as elderly people and persons with physical disabilities can use the room in their rooms or hospital rooms.

  In recent years, in order to facilitate the cleaning of the local area of the care recipient, Japanese Patent Application Laid-Open No. 2002-282164 (Patent Document 1), Japanese Patent Application Laid-Open No. 2006-122664 (Patent Document 2), and Japanese Patent Application Laid-Open No. 2006-87724. (Patent Document 3), JP-A-2008-73094 (Patent Document 4), JP-A-2005-152340 (Patent Document 5) and JP-A-2002-78641 (Patent Document 6). As can be seen, chair-type portable toilets with cleaning devices are also popular. A chair-type portable toilet with a cleaning device is mainly a chair-shaped toilet main body with a backrest, a waste container bucket, a toilet seat, a seat covering the toilet seat, a cleaning device, and the cleaning device. It is comprised from the water supply tank for supplying washing water.

  Furthermore, in recent years, there is a tendency that the harmony and design in the room of a portable toilet are regarded as important. Therefore, the portable toilet is finished in furniture style, or devices and equipment are stored in the area of the portable toilet body so that each device and equipment is difficult to see from the outside. Yes. However, in the case of a chair-type portable toilet with a cleaning device, a water supply tank must be provided in addition to the cleaning device, so the presence of the water supply tank may be an obstacle to designing a portable toilet compactly or partly. There was a problem of disabling the highly convenient function.

  For example, in the chair-type portable toilets with cleaning devices disclosed in Patent Documents 1 to 4, the water supply tank is installed vertically in consideration of the ease of installing and removing the water supply tank and the ease of replenishing the cleaning water to the tank. A structure in which the water supply tank is arranged outside the toilet main body, such as behind the washing device and the backrest, after the flat shape of the mold is adopted.

  However, in this type of portable toilet, if the seat (or lid) covering the toilet seat is connected to the toilet body so that it can be opened and closed, the water supply tank becomes an obstacle, and the seat (or lid) is moved to the back of the backrest. There is a restriction that it cannot be moved (see, for example, FIG. 1 of Patent Document 4 and FIG. 2 of Patent Document 5). Moreover, since the water supply tank is exposed in appearance, there is a problem that the appearance of the portable toilet is deteriorated.

  Furthermore, in the case of the portable toilet described in Patent Document 4, the seat portion covers the upper surface of the toilet seat and becomes a seat portion in a horizontal position where the seat portion is seated on the toilet seat, and is supported as shown in FIG. When standing up in a folded state through the member, it can be used as a backrest having a cushioning property by abutting against the backrest portion of the chair member when adding use.

  However, when the portable toilet is used as a chair and the sitting position of a human when used as a toilet is basically the same, in the case of the portable toilet described in Patent Document 4, There is a problem in that the depth of the seating surface of the seat, or the distance from the toilet tip of the backrest or the height of the backrest is an inappropriate size that hinders humans from sitting comfortably.

  For example, if the seating position of a person when used as a toilet is designed as a correct position, the backrest of the chair member must be placed in an excessively backward position in advance by the thickness of the seat. When used as a chair member, the back of the chair member is in an unnatural position that has been retracted too much for a human to sit comfortably. On the other hand, if the seating position of a person when using a portable toilet as a chair is designed as the correct position, the seat surface of the seat that is raised in a folded state when used as a toilet advances forward by that thickness. Therefore, the position of the seat when used as a toilet is an unnatural position that has been advanced too much for a human to sit comfortably. These problems occur similarly when the depth of the seating surface of the seat is adjusted.

  Considering the compactness and design of the portable toilet, for example, as shown in FIG. 1 of Patent Document 1 and Patent Document 6, a chair type with a cleaning device in which a water supply tank is disposed below the cleaning device. Portable toilets are also known. However, in this type of portable toilet, a space for storing the water supply tank must be provided in the lower part of the cleaning device, so the cleaning device must be placed relatively close to the backrest and relatively above the portable toilet. There was a design constraint. Therefore, even in a portable toilet in which a water supply tank is disposed below the cleaning device, if the seat (or lid) covering the toilet seat is connected to the toilet body so that it can be opened and closed, the cleaning device becomes an obstacle and the seat (or There is a restriction that the lid portion cannot be moved to the back of the backrest (see, for example, FIG. 1 of Patent Document 4 and FIG. 2 of Patent Document 5).

  In addition, when the water supply tank is arranged below the cleaning device, when supplying the water to the water supply tank, the water supply tank must be taken out by turning the hand to the lower part of the back side of the water supply tank body. It was inconvenient to put in and out of the water tank from the foot, putting a burden on the legs. In addition, even when the cleaning water is directly supplied to the water supply tank without taking out the water supply tank, there is a problem in that it is necessary to bend over and supply the foot, which places a burden on the legs.

  As described above, the conventional portable toilet equipped with a cleaning device has a problem in that when the toilet is used, the user cannot use the backrest of the toilet and cannot defecate in a relaxed state. Moreover, as shown in Patent Documents 1 to 3 and 6, by making the seat (or the lid) completely removable from the toilet body, the backrest can be used even when using the toilet. However, in this case, each time the toilet is used, the seat (or lid) must be removed from the toilet body and rented around the toilet, so that it takes time to use the toilet.

  Furthermore, there is a problem that borrowing the seat (or the lid) is not preferable in terms of hygiene, and the water supply tank arranged below the cleaning device is taken in and out of the tank, supplied with cleaning water to the tank, and supplied to the tank. There is also a problem that the handling of the pump hose is inconvenient.

JP 2002-282164 A JP 2006-122664 A JP 2006-87724 A JP 2008-73094 A JP 2005-152340 A JP 2002-78641 A

  Therefore, the present invention provides a chair-type portable toilet equipped with a cleaning device having a seat (or lid) connected to the toilet body so as to be openable and closable. It is an object of the present invention to provide a space-saving portable toilet that can use the backrest of the toilet body without removing the toilet seat (or lid) from the toilet body.

  In the chair type portable toilet equipped with a cleaning device, the present inventors can use a seat back (or lid) mounting structure, a cleaning device, a water supply tank, and the like so that the backrest of the toilet can be used when the toilet is used. As a result of intensive studies on the layout of equipment and equipment, the toilet tank seat (or lid) is folded in half by placing a thin water supply tank in the space below the cleaning device. In this state, the above-described problem has been solved by allowing the lower part of the backrest to be pivoted downward or backward.

  In addition, the inconvenience of handling the water tank caused by placing the water tank in the space below the cleaning device, or the instability of the balance of the water tank caused by making the water tank thin, This was solved by devising the shape of the water supply and the structure for mounting the water supply and portable toilet.

  That is, according to the present invention, a toilet body portion in the shape of a chair having a backrest, a waste container bucket, a toilet seat, and a foldable seat portion that covers the toilet seat, the seat portion with respect to the toilet seat A seat part that is directly or indirectly attached to the toilet body part so as to be openable and closable; a cleaning device for cleaning the human body part; and a thin water supply tank for supplying cleaning water to the cleaning device; The water supply tank is disposed in the space behind the waste container bucket and below the cleaning device, so that the seat portion is folded in two and the backrest is placed. There is provided a portable toilet that can be rotated downward or behind the backrest through an opening formed between the cleaning device and the cleaning device.

  Here, the front or front side of the portable toilet means a direction in which the user's stomach faces when the user is seated on the toilet seat or the seat. Therefore, the rear or rear side of the portable toilet means a direction in which the user's back faces when the user is seated on the toilet seat or the seat.

  The portable toilet of the present invention is mainly a chair-shaped toilet main body having a backrest, a waste container bucket, a toilet seat, and a seat that can be folded in two to cover the toilet seat, and the toilet main body can be opened and closed with respect to the toilet seat. It comprises a seat part which is directly or indirectly attached to the part, a cleaning device, and a water supply tank for supplying cleaning water to the cleaning device.

  In the portable toilet of the present invention, the water supply tank has a horizontal and relatively thin shape, and the water supply tank is disposed behind the waste container bucket and in the space below the cleaning device. The device can be placed as far down as possible from the backrest. Therefore, in the portable toilet of the present invention, an opening through which the seat folded in half can pass can be formed between the backrest and the cleaning device, and as a result, the seat can be folded back in the folded state. Through an opening formed between the cleaning device and the cleaning device, it is possible to rotate the backrest downward or behind the backrest.

  As a result, in the chair type portable toilet with the cleaning device according to the present invention, the user can use the chair as a toilet even when the chair is used as a chair even though the seat is connected to the toilet body so as to be opened and closed. However, the backrest of the toilet body can be used directly without removing the toilet seat from the toilet body.

  In the present invention, the seat portion may have any seat surface on which the user sits and covers the toilet seat. Therefore, the seat portion may also serve as the lid portion of the waste container, or the bucket lid portion may be provided separately and configured as a separate body from the lid portion.

  Also, the seat can be folded in two so that it can pass through the opening between the backrest and the cleaning device. For this reason, the seat part consists of a front half part and a rear half part, the rear half part of the front half part is rotatably connected to the front end part of the rear half part, and the rear half part is directly connected to the rear end part. Or, it is rotatably attached to the toilet body part indirectly via an arm extending from the latter half part.

  In the portable toilet of the present invention, the inconvenience of handling the water tank caused by placing the water tank in the space below the cleaning device, the instability of the balance of the water tank due to the thin shape of the water tank, etc. Therefore, in the shape of the water supply tank and the attachment structure between the water supply tank and the toilet body, the following measures are taken.

  That is, the water supply tank used in the portable toilet of the present invention is provided on the tank body including at least the upper wall, the lower wall, the left wall, the right wall, the front wall and the rear wall, and the rear wall of the tank body. And a water supply port extending from the tank main body, the opening surface of the water supply port being located above the upper surface wall of the tank main body, and the center of the opening surface being the center of the tank main body It is comprised from the said water supply opening arrange | positioned so that it may be located back from a rear surface wall.

  The tank body is generally composed of a hexahedron including an upper wall, a lower wall, a left wall, a right wall, a front wall, and a rear wall. However, the number and shape of the wall are not particularly limited, and the tank body is a polyhedron with more walls. It may be a polyhedron or a spherical body including a spherical surface with fewer wall surfaces. However, since the water supply tank must be arranged in a limited space behind the waste container and below the cleaning device, in the case of the present invention, at least in order to effectively use the space. It preferably includes an upper wall, a lower wall, a left wall, a right wall, a front wall, and a rear wall.

  Furthermore, in the side view, when the average height H between the upper surface wall and the lower wall of the tank main body described above is smaller than the average length L between the front wall and the rear wall, the water supply tank is more Since the thin shape is flattened in the plane direction, the arrangement height of the cleaning device arranged above the arrangement can be advantageously reduced.

  Thus, it is desirable that the water supply tank used in the present invention has a thin shape that is relatively flat in the plane direction. However, if the tank has such a shape, the area of the lower surface increases, so that even when the cleaning water remains sufficiently, the liquid level is lowered and the cleaning water cannot be sucked by the pump of the cleaning device. . Therefore, in the water supply tank used in the present invention, a hose connected to the pump of the cleaning device is provided on the inner surface side of the lower surface wall of the tank main body so that the cleaning water in the tank can be sucked almost without leaving. The suction port is set and a concave portion is provided for collecting the small amount of cleaning water to locally increase the liquid level.

  The water supply tank used in the present invention includes a handle and a water supply port. The handle is provided on the rear wall of the tank body. The water supply port extends from the tank body, the opening surface of the water supply port is located above the upper surface wall of the tank body, and the center of the opening surface of the water supply port is behind the rear wall of the tank body. It is arranged to be located. That is, the water supply port is disposed in the vicinity of the corner formed by the upper surface wall and the rear wall of the tank main body.

  If the handle is provided on the rear wall of the tank body, even with a water supply tank that has entered the lower part of the cleaning device, water can be supplied in one operation without releasing the handle by grasping the handle with a human hand. The tank can be taken out from the storage space of the toilet body. The position of the handle is not particularly limited as long as it is provided on the rear wall of the tank body. However, if the handle is provided on the upper side of the rear wall, the replenisher bends when taking out the water supply tank. This is convenient because it can reduce the amount that must be provided.

  If the water supply port is also arranged as described above, it is possible to reduce the degree to which the replenisher has to bend down when supplying the water directly to the water supply tank without removing the water supply tank from the portable toilet. It is. Even when the water tank is removed from the portable toilet and replenished with cleaning water, when the water tank is lifted by supporting the handle, the water supply port faces upward, which is convenient for replenishing the cleaning water. Good.

  Therefore, if the tank body is lifted by supporting the handle so that the opening surface of the water supply opening of the water supply tank is substantially horizontal, liquid spilling from the water supply opening during replenishment can be reduced. It is preferable because it is possible.

  Further, the water supply port may include a guide path that is inclined rearward from the vertical direction. In this case, the guide path may be, for example, a cylindrical passage, or may be a groove-like passage that partially forms a part of the wall surface of the water supply tank.

  If the water supply port is thus provided with the guide path, the water supply port can be arranged further upward and / or rearward from the tank main body, so that the water supply tank as described above is disposed in the space below the cleaning device. The inconvenience of handling caused by disposing it inside can be almost eliminated. In addition, since the washing water can be replenished smoothly via the guide path, it is possible to further reduce the scattering of the washing water from the water supply port during replenishment.

  Furthermore, the water supply tank has a guide shaft that is substantially vertical when the tank body is lifted by supporting the handle, regardless of whether the guide passage is cylindrical or groove-shaped. By disposing, the cleaning water can be replenished more smoothly through the guide path during replenishment.

  The front wall of the water supply tank preferably has a shape tapered from the rear end to the front end of the tank main body in a plan view.

  If the tip of the water supply tank is sharpened, when replenishing cleaning water while the water supply tank is lifted, the cleaning water in the initial stage of replenishment gathers near the center of the front end of the tank body, and gradually from the center. It accumulates so as to spread to the left and right side walls. For this reason, during the replenishment of the wash water, the tank shake and abnormal tilt caused by the wash water being biased in the tank are suppressed, and the stability of the tank when supporting the handle of the tank with one hand is greatly improved. .

  In addition, in order to further suppress the bias in the tank of the cleaning water being replenished and further reduce the fluctuation of the tank and the abnormal inclination, the front end region and the rear of the internal space of the tank main body are moved to the tank main body. Except for the end region, it is preferable to provide a partition wall that divides the internal space of the tank main body into two in the width direction.

  In this case, since the wash water being replenished is obstructed by the partition wall moving in the width direction inside the tank body, the tank shake or abnormalities caused by the wash water moving in the width direction in the tank The tilt is more effectively suppressed and the balance of the tank is maintained. In this type of water tank, in order to maintain the balance of the tank, it is necessary to keep the level of each cleaning water collected in both spaces divided by the partition wall evenly. No partition walls are arranged in the front end region and the rear end region of the internal space of the tank body so that the cleaning water can move in the width direction.

  In the portable toilet according to the present invention, as described above, the water supply tank can be smoothly taken out from the storage space of the toilet body part without being released from the handle, or stored in the storage space. In this case, it is preferable that the water supply tank is supported by the toilet body part so as to be slidable directly or indirectly.

  In this case, as one specific example, by providing a flange part or a pin on the left side wall and the right side wall of the tank body part, and supporting the flange part or the pin with a shelf part provided in the toilet body part, The water supply tank can be slidably supported with respect to the toilet body.

  As another specific example, a slot extending from the front end to the rear end is provided on the left side wall and the right side wall of the tank main body, and a shelf or a pin provided in the toilet main body is inserted into the slot. Thus, the water supply tank can be slidably supported with respect to the toilet body.

  As another specific example, a water supply tank is placed on a tray, the tray is mounted on a reinforcing subframe of the toilet body, and the subframe is fixed to the toilet body. Also, the water supply tank can be slidably supported with respect to the toilet body through the tray. Moreover, you may support so that a water supply tank can be slid with respect to tray itself by fixing a tray to a toilet main-body part by a fixing means. If a tray is used to support the water supply tank, the tray can be slid to make it easy to put in and out of the water supply tank, and the tray does not spill liquid spills or dripping that occurs when cleaning water is replenished. Can take it.

  When the tray is slidably mounted on the sub-frame of the toilet body, it is preferable to provide a stopper at the edge of the tray and to provide a stopper receiving portion that contacts the stopper on the sub-frame.

  In this case, the tray is prevented from sliding out of the toilet body part unintentionally because the slide movement on the subframe is restricted in the middle by the stopper and the stopper receiving part coming into contact with each other. . In addition, the tray can be lifted from the toilet body when maintenance is performed because the rear end of the tray is separated upward from the subframe so that the restriction on sliding movement can be released. It is. It should be noted that the stopper at the edge of the tray and the stopper receiving portion of the subframe may be any projection / projection that can abut against each other in the moving direction, and the structure is not particularly limited. Absent.

  Preferably, the tray is provided with a fixing means made of an eccentric member that rotates in conjunction with the knob, and the subframe is provided with a punch hole having a receiving port for receiving the eccentric member from the horizontal direction.

  In this case, the tray can be fixed non-slidable or non-slidable relative to the subframe by rotating the knob. In addition, when the tray is fixed to the subframe so as not to slide, the tray can be prevented from unexpectedly sliding backward when the toilet is tilted and moved so that the water supply tank jumps out backward. At the same time, since the water supply tank is easily slid on the fixed tray, the water supply tank can be easily taken out from the toilet body by a single operation.

  When the water supply tank is slidably supported with respect to the toilet body through the tray, the tray can be directly mounted on the toilet body without being mounted on the subframe of the toilet body. For example, by placing the water supply tank on a tray having at least a pair of parallel flange portions at the edges, and supporting the flange portion of the tray with a shelf provided in the toilet body portion, the water supply tank is It can be slidably supported on the toilet body through the tray.

  According to the present invention, in a chair-type portable toilet equipped with a cleaning device having a seat (or a lid) connected to the toilet body so as to be openable and closable, the user uses the toilet even when used as a chair. Even in such a case, a space-saving portable toilet that can use the backrest of the toilet body without removing the toilet seat (or lid) from the toilet body is provided.

  In addition, according to the present invention, a portable toilet suitable for the use of a water supply tank having a special shape so that it can be taken out from the storage space of the toilet body by a single operation without releasing the hand from the handle. Is provided. Therefore, according to the present invention, when the water supply tank is taken in and out, or when the washing water is directly supplied to the water supply tank without taking out the water supply tank, the replenisher must bend down to achieve those purposes. The extent of not being reduced.

  Hereinafter, a portable toilet according to an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the examples shown below, and various modifications can be made without departing from the technical idea of the present invention.

  A main configuration of a portable toilet according to an embodiment of the present invention will be described with reference to FIGS. 1A to 2B and FIGS. 1A and 2A show a state when the portable toilet seat of the present embodiment is closed, and FIGS. 1B and 2B show a state when the portable toilet seat of the present embodiment is opened. Yes. 3 and 4 show side sectional views of the portable toilet according to this embodiment when the seat portion is closed and when the seat portion is opened.

  As shown in FIGS. 1A to 4, the portable toilet 1 according to the present embodiment mainly covers a toilet body 2 having a chair shape with a backrest, a waste container bucket 3, a toilet seat 4, and the toilet seat 4. A seat part 5 that can be folded in two, which is directly or indirectly attached to the toilet body 2 so as to be openable and closable with respect to the toilet seat 4, a cleaning device 6, and a cleaning water to the cleaning device 6. And a water supply tank 7 for supplying water.

  Also, the toilet body 2 includes a chair-shaped portable toilet back 21 and armrest 22 and a heel 23 that supports them, a decorative plate 24 that forms the side surface of the toilet body, and the toilet body is stable to the floor. A horizontal leg portion 25 with a roller for installation is included.

  Here, the front or front side of the portable toilet 1 means a direction in which the user's stomach is facing when the user is seated on the toilet seat 4 or the seat portion 5. Accordingly, the rear or rear side of the portable toilet 1 means a direction in which the user's back faces when the user is seated on the toilet seat 4 or the seat portion 5.

  As shown in FIGS. 3 and 4, the seat portion 5 of the portable toilet 1 of the present embodiment has a seat surface 51 suitable for the user to sit on, and is folded in two. The seat 5 is composed of a front half 52 and a rear half 53 so that it can be folded. The rear half 54 of the front half 52 of the seat part 5 is connected to the tip 55 of the rear half 53 by a hinge so that the rear half 54 is rotatable. The rear half 53 is connected to an arm 57 extending from the rear edge 56. And indirectly attached to the bowl 23 of the toilet body 2 (see FIG. 5).

  Moreover, since the seat part 5 of this embodiment covers all of the toilet seat 4 when it is closed, it also functions as a lid for the waste container bucket 3 positioned below the seat part 5. However, in this embodiment, in order to ensure prevention of odor diffusion from the filth case bucket 3, a lid portion 31 dedicated to the filth case bucket is prepared separately from the seat portion 5, and the lid portion 31 is removed. It is designed so that it can be stood behind the portable toilet 1 so that it can be placed temporarily without sacrificing extra space (see FIG. 4).

  On the other hand, the water supply tank 7 used in the portable toilet 1 of this embodiment has a thin shape that is horizontal and relatively flat in the horizontal direction, as shown in FIGS. 2A, 2B and FIGS. The portable toilet 1 is disposed behind the waste container bucket 3 and below the cleaning device 6. For this reason, the cleaning device 6 can be disposed at a low position away from the backrest 21, and a large opening 26 is formed between the cleaning apparatus 6 and the backrest 21.

  In the portable toilet 1 of the present embodiment, by adopting the configuration as described above, when the toilet is not used, the seat 5 is tilted on the toilet seat 4 so that the chair using the backrest 21 of the toilet body 2 can be used. Can be used (see FIGS. 1A, 3). On the other hand, when using the toilet, the seat 5 is folded in half, passed through the opening 26 formed between the backrest 21 and the cleaning device 6, and rotated to a position below the backrest 21 so as not to interfere. (See FIGS. 1B and 4). As a result, in the portable toilet 1 of the present embodiment, the seat 5 is connected to the toilet body 2 so that it can be opened and closed. The backrest 21 of the toilet body can be directly used at the position as it is without removing it from 2 (see FIGS. 1B, 2B, 4). FIG. 4 shows a state in which the seat 5 is folded in two and the toilet seat 4 is also flipped upward in order to replace the waste bucket 3.

  Next, the main configuration of the water supply tank 7 for the cleaning device used in the portable toilet 1 of the present embodiment will be described with reference to FIGS.

  FIG. 6 shows an outline of the water supply tank 7, and FIGS. 7A to 7C show the plane, side, and front of the water supply tank 7. As can be understood from FIGS. 6 and 7B, the water supply tank 7 of this embodiment is disposed in a limited space behind the waste container 3 of the portable toilet 1 and below the cleaning device 6. As a whole (see FIGS. 3 and 4), as a whole, it is a horizontal type and has a thin special shape that is flattened in a relatively horizontal direction. Further, in this embodiment, the inconvenience of handling the water supply tank 7 caused by arranging the water supply tank 7 in the space below the cleaning device 6 and the balance of the water supply tank 7 due to the thin shape of the water supply tank 7. Therefore, various ingenuity has been applied to the shape of the water supply tank 7 and the mounting structure of the water supply tank 7 and the toilet body 2.

  Specifically, as shown in FIGS. 6 to 7C, the water supply tank 7 used in this embodiment includes an upper surface wall 710, a lower surface wall 711, a left side wall 712, a right side wall 713, a front wall 714, and a rear side. The tank main body 71 includes a surface wall 715, a handle 72 provided on the rear wall 715 of the tank main body 71, and a water supply port 73 extending from the tank main body. Further, the opening surface 74 of the water supply port 73 is disposed above the upper surface wall 710 of the tank body 71 and the center of the opening surface 74 is disposed behind the rear wall 715 of the tank body 71. Yes.

  Further, as shown in FIG. 7B, the water supply tank 7 of the present embodiment has an average height H between the upper surface wall 710 and the lower surface wall 711 of the tank main body portion 71 in the side view, as shown in FIG. Since the average length between 714 and the rear wall 715 is smaller than L, it has a thin shape flattened in the plane direction as a whole. Therefore, the arrangement height of the cleaning device 6 disposed above the water supply tank 7 can be kept low, and conversely, the interval between the cleaning device 6 and the backrest 21 can be widened (FIGS. 3 and 4). reference).

  FIG. 10 shows a bottom view of the water supply tank 7 shown in FIG. 6 as viewed from the bottom. FIG. 11 shows the water supply tank 7 shown in FIG. A cut-away sectional view is shown. As shown in FIGS. 10 and 11, in the water supply tank 7 of this embodiment, since the cleaning water in the tank is sucked by the hose 61 (FIGS. 2A and 2B) connected to the pump of the cleaning device 6, the tank On the inner surface side of the lower surface wall 711 of the main body 71, a recess 75 is provided for setting the suction port of the hose 61 and collecting and storing the washing water locally. The recess 75 collects a small amount of the cleaning water in the tank, and allows the cleaning water to be easily sucked from a position substantially directly below the two water supply ports 73 provided in the tank. It is connected in a groove shape along the corner portion (see FIG. 10).

  The reason for this is that if the water supply tank is generally thin and flat in the plane direction, the area of the lower surface of the tank increases. It becomes impossible to suck the washing water with the pump. However, if the recess 75 is provided in the lower wall 711 of the tank main body 71 like the water supply tank 7 of the present embodiment, a small amount of cleaning water collects in the recess 75 and locally increases the liquid level. This is because it becomes possible to suck the cleaning water in the tank from the recess 75 without leaving much.

  The water supply tank 7 includes a handle 72 and a water supply port 73 (see FIG. 6). As shown in FIGS. 7A and 7B, the handle 72 is provided on the rear wall 715 of the tank main body 71. The water supply port 73 extends from the tank main body 71, the opening surface 74 of the water supply port 73 is located above the upper surface wall 710 of the tank main body 71, and the center of the opening surface 74 of the water supply port 73 is the tank. It arrange | positions so that it may be located behind the rear surface wall 715 of the main-body part 71. FIG. That is, the water supply port 73 is disposed in the vicinity of the corner formed by the upper surface wall 710 and the rear surface wall 715 of the tank main body 71.

  When the handle 72 is provided on the rear wall 715 of the tank main body 71, the handle 72 is gripped by a human hand even when the water supply tank 7 is flattened in the plane direction and has entered under the cleaning device 6. Thus, the water supply tank 7 can be easily taken out from the storage space of the toilet body 2 by a single operation without releasing the hand. Further, in this embodiment, the handle 72 is provided above the rear wall 715 of the tank main body 71. Therefore, when the water supply tank 7 is taken out, the extent to which the replenisher has to bend down can be reduced. So convenient.

  On the other hand, the arrangement of the water supply port 73 as described above also reduces the extent to which the replenisher has to bend down when supplying the wash water directly to the water supply tank 7 without removing the water supply tank 7 from the portable toilet 1. It is convenient because it can. Further, even when the water supply tank 7 is taken out from the portable toilet 1 and replenished with cleaning water, when the water supply tank 7 is lifted by supporting the handle 72, the water supply port 73 faces upward so that replenishment of the cleaning water is performed. Is convenient (see FIG. 8).

  As understood with reference to FIG. 8, the opening surface 74 of the water supply port 73 of the water supply tank 7 of this embodiment is substantially horizontal when the tank body 71 is lifted by supporting the handle.

A partition wall 78 that divides the internal space of the main body into two in the width direction is provided. For this reason, in the water supply tanks 7 and 7 ′ of this embodiment, the bias in the tanks 7 and 7 ′ of the wash water being replenished is further suppressed, and the fluctuations and abnormal inclinations of the tanks 7 and 7 ′ are further increased. It is reduced.

  As described above, when the internal space of the tank body is divided into two in the width direction by the partition wall 78, it is obstructed that the cleaning water being supplied moves in the width direction in the tank body by the partition wall 78. Therefore, the shake and abnormal inclination of the tanks 7 and 7 'caused by the movement of the washing water in the width direction in the tanks 7 and 7' are further effectively suppressed, and the balance of the tanks 7 and 7 'is maintained. Be drunk. In addition, in the water supply tanks 7 and 7 ′ of the present embodiment, the level of the cleaning water accumulated in both spaces divided by the partition wall 78 is equalized in order to keep the balance of the tanks 7 and 7 ′. The partition wall 78 is not disposed in the front end region 716 and the rear end region 717 of the internal space of the tank body so that the cleaning water can partially move in the width direction.
