  The above-described conventional technology has various problems to be solved. Since the present invention has been made by comprehensively examining and reconstructing aspects of these various problems to be solved, the aspects of these problems will be described subsequently.

  The aspect of the first problem to be solved is as follows. The configuration as shown in FIG. 23 can prevent reverse connection between the water supply route and the drainage route. However, as shown in FIG. Although not shown, the hose 52 may be contacted, or the water supply hose 51 may be brought into contact with the drain plug 54. Since the joint portion between the drain plug 54 and the drain hose 52 is often attached with dirty water, the male joint 52m of the drain hose 52 is brought into contact with the male joint 53m of the water tap 53, or the female joint 54f of the drain plug 54. If the female joint 51f of the water supply hose 51 is brought into contact with the water supply hose 51, the joint portion of the water supply tap 53 or the water supply hose 51 may be soiled, which may adversely affect the water supply path.

  Further, in the conventional connection structure, as shown in FIGS. 23 and 25, when the male joint 52m of the drain hose 52 is separated from the female joint 54f of the drain plug 54, it adheres to the inner peripheral surface and the like of the female joint 54f. The residual sewage water DW may fall and soil the floor and the like. In addition, in order to avoid that drawing becomes difficult to see, description of cross-sectional hatching is abbreviate | omitted in FIG.

  The second aspect of the problem to be solved is as follows. Although the reverse connection between the water supply path and the drainage path can be prevented by adopting the configuration as shown in FIG. 23, the drainage hose 52 is detached from the drainage plug 54 in the pressure-feed mobile toilet 50 shown in FIG. It is left to the operator to close the open / close valve 52a on the drainage hose 52 side in advance. For this reason, the male joint 52m of the drain hose 52 may be separated from the female joint 54f of the drain plug 54 while the open / close valve 52a on the drain hose 52 side is opened.

  As described above, when the drainage operation on the toilet body 50a side of the pressure-feed movable toilet 50 is performed when the opening / closing valve 52a on the drainage hose 52 side separated from the female joint 54f of the drainage plug 54 is in an open state, There is a possibility that sewage flows out of the male joint 52m of the hose 52. Similarly, when the draining operation on the toilet body 50a side of the pressure-feed movable toilet 50 is performed in a state where the male joint 52m of the drain hose 52 is not completely connected to the female joint 54f of the drain plug 54, the connection is similarly performed. There is a risk of sewage flowing out of the gap between the parts.

  The third aspect of the problem to be solved is as follows. As shown in FIGS. 21 and 22, in the case of the conventional pumping mobile toilet 50, in the connecting portion between the water supply hose 51 and the drainage hose 52 and the water supply tap 53 and the drainage plug 54 extending from the toilet body 50 a. Since the members constituting the water supply joint structure 50x and the drainage joint structure 50y are exposed (projected) from the wall surface of the building, there is a possibility that some object, human body, etc. may come into contact with each other and be damaged. Moreover, since the connection part of the drain pipe (not shown) and the drain plug 54 piped on the building side is an adhesive structure, it is difficult to remove after construction.

  As described above, the conventional pumping mobile toilet has various aspects of the problem to be solved. In particular, this pumping mobile toilet is suitable for use in medical sites such as clinics, hospitals, and sanatoriums, and therefore various users such as children and the elderly are assumed, and various accidents as described above are assumed. Need to be dealt with. Therefore, in the present invention, attention is paid to a means for preventing sewage from being ejected when the drainage hose is not attached to the building-side joint. An object of the present invention is to provide a pressure-feed mobile toilet.

In order to solve the above-mentioned problem, a pressure-feed mobile toilet according to the present invention is connected to a fixed-side water supply joint and a fixed-side drainage joint provided on a building side, and a water supply hose and a drainage hose, respectively. In a pressure-feed mobile toilet equipped with a water supply joint and a hose side water supply joint and a hose side drainage joint that are detachably connected to the fixed side drainage joint, the drainage hose includes a drainage hose side opening / closing valve, only when the drainage hose-side valve is closed, the configured fixed side drain joint so that it can be removed the hose side drain fitting Rutotomoni, the stationary water supply joint and the fixed-side water discharge fitting A water supply / drainage support member for supporting the water supply / drainage support member, and detachably attached to the water supply / drainage support member, covering the hose side drainage joint and the fixed side water supply joint, A lock release restricting cover for restricting connection between the water joint and the fixed drainage joint, and the lock release restricting cover is provided only when the drainage hose side opening / closing valve is closed. It is comprised so that it can remove from a water supply / drainage support member, It is characterized by the above-mentioned.

  In the present invention, the hose side drainage joint can be removed from the fixed side drainage joint only when the drainage hose side opening / closing valve provided in the drainage hose is closed. When the hose-side drainage joint is removed from the drainage joint, the drainage hose-side on-off valve is closed. Therefore, in a state where the drain hose is not connected to the fixed drain joint, the drain hose side on-off valve is in a closed state, so that it is possible to reliably avoid a situation where dirty water is ejected from the drain hose due to incorrect use.

  In the case of this aspect, the valve closing restriction of the drainage hose side opening / closing valve is performed by the lock release restriction cover for restricting the release of the connection between the hose side drainage joint and the fixed side water supply joint. To remove the unlocking restriction cover, the drain hose side opening / closing valve must be closed. When the valve is closed, remove the unlocking restriction cover and remove the hose drainage joint from the fixed drainage joint. Therefore, the drainage hose can be reliably removed only when the valve is closed by a simple mechanical component called the unlocking restriction cover. Therefore, it is possible to reliably avoid a situation in which dirty water is ejected from the drainage hose due to incorrect use.

Further, in the pressure-feed mobile toilet according to claim 2 of the present application, the fixed-side drainage joint is provided with a fixed-drainage on-off valve, and the fixed-side water supply joint and the fixed-side drainage joint for supporting the fixed-side drainage joint, A lock release restriction that is detachably attached to the water supply / drainage support member, covers the drainage hose side opening / closing valve and the fixed drainage side opening / closing valve, and regulates the disconnection of the hose side drainage joint and the fixed side drainage joint. And the unlocking restriction cover is configured to be removable from the water supply / drainage support member only when both the drainage hose side opening / closing valve and the fixed drainage side opening / closing valve are closed. It is characterized by being.

  In this case, the drain hose side open / close valve and the fixed drain side open / close valve are closed by a lock release restriction cover for restricting the release of the connection between the hose side drain joint and the fixed side water supply joint. In order to remove the lock release restriction cover, the drain hose side open / close valve and the fixed drain side open / close valve must be closed. Since the side drainage joint can be removed, the drainage hose can be surely removed only when the valve is closed by a simple mechanical component called the unlocking restriction cover. Therefore, it is possible to reliably avoid a situation in which dirty water is ejected from the drainage hose or the fixed-side drainage joint due to incorrect use. The water supply / drainage support member of the present invention only needs to be able to support the fixed side water supply joint and the fixed side drainage joint and provide an unlocking restriction cover, so that a plate-like member, a box-like member, or a combination of these members It is also preferable that it is configured as a part of the wall surface of the building.

Further, in the pressure-feed mobile toilet according to claim 3 of the present application, the fixed drainage joint is provided with a fixed drainage on-off valve, and a water supply / drainage support member for supporting the fixed water supply joint and the fixed drainage joint, A lock release restriction cover that is detachably attached to the water supply / drainage support member, and the lock release restriction cover exposes the operation portions of the drainage hose side opening / closing valve and the fixed drainage side opening / closing valve, respectively, The hose-side drainage joint and the fixed-side drainage joint, and a release portion for releasing a locking mechanism between the hose-side drainage joint and the fixed-side drainage joint are configured to cover.

  In this aspect, the lock release restricting cover exposes the operation parts of the drain hose side on-off valve and the fixed drain side open / close valve, so the drain hose side on / off valve and the fixed drain side on / off valve are closed to release the lock release restricting cover. The hose side drainage joint can be removed from the fixed side drainage joint. Furthermore, the lock release restriction cover covers the hose side drainage joint and the fixed side drainage joint and also covers the release part for releasing the lock mechanism of these joints. A situation in which the connection between the joint and the fixed-side drain joint is released can be reliably avoided.

Further, in the pressure-feed mobile toilet according to claim 4 , the water supply / drainage support member for supporting the fixed side water supply joint and the fixed side drainage joint, and the hose side drainage are detachably attached to the water supply / drainage support member. Rutotomoni and a unlock preventing cover for regulating the disconnect between the joint and the stationary drainage fittings, with a fixed drainage on-off valve on the stationary drainage fittings, the unlock preventing cover, the hose When the connection state between the side drainage joint and the fixed side drainage joint is not a normal state, the drainage hose side opening / closing valve and the fixed drainage side opening / closing valve are configured not to be operable. Features.

  In this aspect, when the connection state between the hose-side drainage joint and the fixed-side drainage joint is not a normal state, the drain hose-side on-off valve and the fixed drain-side on-off valve are configured so as not to be operated. Therefore, if the connection between the hose drain joint and the fixed drain joint is not normal, the lock release restriction cover cannot be removed, and the connection between the hose drain joint and the fixed drain joint may be released. It is configured not to be able to. Accordingly, since the sewage does not pass when the connection between the hose side drainage joint and the fixed side drainage joint is not normal and defective, it is possible to reliably prevent the sewage from being ejected from the poorly connected portion.

Further, in the pressure-feed mobile toilet according to claim 5 , the water supply / drainage support member for supporting the fixed side water supply joint and the fixed side drainage joint, the detachable attachment to the water supply / drainage support member, A lock release restricting cover for restricting connection between the joint and the fixed drainage joint, and the lock release restricting cover has a normal connection state between the hose drainage joint and the fixed drainage joint. When it is not in a state, it is configured so that it cannot be fixed to the water supply / drainage support member.

  In this aspect, when the connection state between the hose side drainage joint and the fixed side drainage joint is not a normal state, the lock release regulation cover for regulating the disconnection between the hose side drainage joint and the fixed side drainage joint is supplied and drained. It cannot be fixed to the support member. Therefore, it is possible to reliably prevent poor connection between the hose-side drainage joint and the fixed-side drainage joint.

Further, in the pressure-feed mobile toilet according to claim 6 , the water supply / drainage support member for supporting the fixed side water supply joint and the fixed side drainage joint, and the hose side drainage are detachably attached to the water supply / drainage support member.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. In order to facilitate the understanding of the description, the same constituent elements in the drawings will be denoted by the same reference numerals as much as possible, and redundant description will be omitted.

  A first embodiment of the present invention will be described. FIG. 1 is a perspective view showing a water supply / drainage unit for a pressure-feed mobile toilet according to the first embodiment of the present invention, and FIGS. 2 and 3 are perspective views showing the inside of a storage box constituting the water supply / drainage unit for the pressure-feed mobile toilet. 4 is a perspective view showing a state in which the cover member of the pumping mobile toilet / water supply / drainage unit is detached, and FIG. 5 is a perspective view showing an inner surface side of the cover member.

  As shown in FIGS. 1-4, in the water supply / drainage unit 10 (henceforth the water supply / drainage unit 10) for pumping movement type toilets of this embodiment, the water supply pipe 11 piped by the building (not shown) and A rectangular parallelepiped housing a connecting portion 15 with a pipe line 13s on the side of a water tap (not shown in FIGS. 1 to 5) and a connecting part 16 with a drain pipe 12 and a pipe line 14s on the drain plug 14 side. A shaped storage box 17 is provided. The water supply pipe 11 and the drain pipe 12 are arranged in parallel with the wall in the storage box 17, and a rectangular opening 17 a is provided at a position close to the drain pipe 12.

  As shown in FIG. 4, a water supply hose (not shown in FIGS. 1 to 5) and a water supply hose extending from the toilet body 18 with respect to the drain plug 14 is provided so as to protrude from the front surface 17 f of the storage box 17. 19, a drainage hose 20 is detachably connected via a water supply joint structure 21 and a drainage joint structure 22, respectively, and a detachable cover member 23 that covers the water supply joint structure 21 and the drainage joint structure 22 is provided.

  Thus, the storage box 17 bends the water supply pipe 11 and the drain pipe 12 which protruded from the wall surface of the building with an elbow, and is connected with the pipe lines 13s and 14s via the connection parts 15 and 16, respectively. . Therefore, it is possible to construct the water tap (not explicitly shown in FIGS. 1 to 5) and the drain plug 14 at a high position, and the water supply hose 19 connected to the water tap and the drain plug 14 via a joint structure, The drainage hose 20 can be kept along the height direction on the front surface of the storage box 17. For this reason, in order to ensure the freedom degree for moving the toilet bowl main body 18, the length of the water supply hose 19 and the drainage hose 20 which makes the floor of a building fold can be shortened.

  Further, when it is necessary to remove the water tap (not explicitly shown in FIGS. 1 to 5) or the drain plug 14 for maintenance or replacement of parts, the maintenance worker puts his hand into the storage box 17 from the opening 17a. You can work with it. Moreover, the maintenance work can be performed by removing the water faucet (not explicitly shown in FIGS. 1 to 5) and the drain faucet 14 located on the toilet body 18 side from the connecting portions 15 and 16, so There is no need to move the drain pipe 12 or peel off the wall surface of the building, and the workability is excellent. The same applies to the case where the water supply pipe 11 and the drain pipe 12 are provided so as to protrude from the floor surface of the building.

  A substantially flat support base 24 that supports the cover member 23 is fixed to the front face 17f of the storage box 17 with a plurality of screws (not explicitly shown in FIGS. 1 to 5). A partition plate 24 a that is a regulating member protruding from the water supply joint structure 21 and the drainage joint structure 22 is provided. The partition plate 24 a is provided in a vertical state so as to partition between the water supply joint structure 21 and the drainage joint structure 22. The cover member 23 is attached so as to cover the support base material 24, and a plurality of mounting screws 23a inserted into the screw holes 23b on the left and right side surfaces and the lower surface of the cover member 23 are provided upright on the outer periphery of the support base material 24. The cover member 23 is fixed to the support base 24 by being screwed into the screw hole 24c formed in the rib 24b.

  As shown in FIGS. 4 and 5, the water supply hose 19 and the drainage hose 20 are respectively inserted into the bottom plate 23 g of the cover member 23 located away from the water supply joint structure 21 and the drainage joint structure 22, and the displacement is restricted. Holes 23c and 23d are provided. The insertion holes 23c and 23d are both formed in a U-shaped short tunnel shape. A hose holding member 25 that restricts the displacement of the drainage hose 20 is attached to the support base 24 that is located in the cover member 23. The hose holding member 25 is also formed in a short U-shaped tunnel shape.

  As shown in FIGS. 4 and 5, the cover member 23 is a box in which a substantially half-moon top plate 23 h and a bottom plate 23 g are attached to the top and bottom of a bowl-shaped front panel 23 f that covers the water supply joint structure 21 and the drainage joint structure 22. Shaped member.

  As shown in FIGS. 1 and 4, in the water supply / drainage unit 10, the water supply joint structure 21 and the drainage joint structure 22 are always covered with the cover member 23, thereby avoiding damage due to contact with an object or a human body. can do. Since the cover member 23 has a structure supported by a partition plate 24a provided on a support base 24 fixed to the front surface 17f of the storage box 17, the cover member 23 has high rigidity and is deformed when an external force is applied. Can be prevented. Moreover, since the partition plate 24a partitions between the water supply joint structure 21 and the drainage joint structure 22, the constituent members of the water supply joint structure 21 are prevented from being damaged by the sewage scattered when the drainage joint structure 22 is attached and detached. can do.

  In addition, instead of or in addition to the configuration in which the partition plate 24a prevents the cover member 23 from being deformed, a plate-like or columnar regulating member that can be abutted on the inside of the cover member 23 is screw-fixed to the support base 24. In addition, it is possible to prevent the cover member 23 from being deformed when an external force is applied.

  Moreover, since the displacement of the water supply hose 19 and the drainage hose 20 is regulated by the insertion holes 23c and 23d of the cover member 23, the load due to the external force when the water supply hose 19 and the drainage hose 20 are moved is the water supply joint structure. It is possible to avoid the direct addition to 21 and the drainage joint structure 22. For this reason, damage to the water supply joint structure 21 and the drainage joint structure 22 due to external force can be prevented.

  Further, since the displacement of the drainage hose 20 is regulated by the hose holding member 25 attached to the support base 24 in the cover member 23, the load due to the external force when the drainage hose 20 is moved is drained as described above. It can prevent joining to the joint structure 22, and can protect the drainage joint structure 22 reliably.

  On the other hand, since an opening 17a facing the drain pipe 12 is provided at a position near the drain pipe 12 on the side of the storage box 17, the drain pipe 12 and the water supply pipe 11 can be inspected and replaced using the opening 17a. It is possible and has excellent maintainability. In particular, since the opening 17a is close to the drain pipe 12, the drain pipe 12 can be easily inspected and replaced.

  Subsequently, the first embodiment of the present invention will be further described based on the drawings with a focus on portions corresponding to the joint protection portion and the lock release restriction cover. FIG. 6 is a perspective view showing a part of the drainage path of the pressure-transfer mobile toilet (flush portable toilet) according to the embodiment of the present invention, and FIG. 7 is a perspective view showing a part of the drainage path shown in FIG. 8 is a perspective view of a cover that constitutes the drainage path shown in FIG. 6, and FIG. 9 is a perspective view showing another embodiment relating to the cover. In the following description, the inside of the storage box 17 constituting a part of the water supply / drainage support member referred to in the claims is not constituted as a separate item as in the previous embodiment, but constituted by the wall surface of the building itself. Specifically, a drain pipe 12 or the like is disposed in the wall surface of the building, and an opening 17a is provided on the wall surface so that a water stop operation can be performed. It demonstrates as what shows the form which fixed the support member 24 mentioned later directly. Therefore, the storage box 17 is configured by the wall surface of the building.

  In the pumping mobile toilet of this embodiment, as shown in FIGS. 6 and 7, a drain plug provided in a building with a drain hose 20 extending from a toilet body (not explicitly shown in FIGS. 6 to 12). 14 is provided with a detecting means 20y that emits a signal only when the drainage hose 20 is connected to the drain plug 14 in a normal state. The detection means 120 includes a magnet 120a as an operation means and a reed switch 120b as a signal generation means. The magnet 120a is attached to the hose holding member 25 (cover), and the reed switch 120b is provided in the drain hose 20. . As shown in FIG. 7, when the drain hose 20 is connected to the drain plug 14 in a normal state, the hose holding member 25 (cover) is attached, and the magnet 120a and the reed switch 120b are in a predetermined facing state, the lead A signal is transmitted from the switch 120b toward the toilet body (not explicitly shown in FIGS. 6 to 12), and based on this signal, the drainage operation of the pumping mobile toilet can be performed.

  Specifically, the toilet main body (not explicitly shown in FIGS. 6 to 12) is the same as the toilet 50a shown in the conventional example of FIG. 21 and includes a waste crushing means and a drain pump, and drains from the reed switch 120b. A signal cable (not shown) embedded in the hose 20 is connected to control means for controlling the crushing means of the toilet body and the drainage pump. When there is a signal from the reed switch 120b to the control means, the control means can operate the drainage operation by driving the crushing means and the drainage pump based on the operation of the toilet cleaning switch by the user.

  On the other hand, as will be described later, when there is no signal from the reed switch 120b, even if there is a toilet flushing switch operation of the user, it is programmed not to drive the crushing means and the drainage pump. Pumping of water from the toilet to the drainage hose 20 is prohibited. In addition, when the situation which does not drive a crushing means or a drainage pump has generate | occur | produced at the time of a user's toilet bowl washing | cleaning switch operation, it is preferable to alert | report to a user by alerting | reporting means, such as LED and a buzzer. Further, when the reed switch 120b is not connected, the fact may be displayed by an LED (not shown) regardless of whether or not the user operates the toilet flushing switch.

  As shown in FIG. 6, a substantially flat support base 24 (attachment member) is fixed to the wall surface on which the drain plug 14 is arranged by a plurality of screws N1, and a hose is held on the support base 24 (attachment member). The member 25 (cover) is detachably attached with a plurality of screws N2. The hose holding member 25 (cover) is detachable only when the drain hose 20 is connected to the drain plug 14 in a normal state. In addition, the support base material 24 (attachment member) is not shown clearly in the connection part of the drain plug 14 and the drain hose 20, the water tap (not shown in FIGS. 6-12), and the water supply hose (FIGS. 6-12). ) Is a member for fixing a protective cover (not explicitly shown in FIGS. 6 to 12) that covers the connecting portion.

  As shown in FIG. 8, the hose holding member 25 (cover) includes a front panel 25a parallel to the support base (see FIG. 7), and a support base 24 from the upper edge and the lower edge of the front panel 25a. Fixed panels 25b and 25c extending toward the (attachment member), and a partition panel 25d extending from one side edge of the front panel 25a toward the support base material 24 (attachment member). Yes. A holding portion 25e having a U-shaped cross section for holding the drainage hose 20 is provided on the fixed panel 25c positioned below.

  The front panel 25a is provided with two through holes 123 and 124 into which the opening / closing handle 14a of the drain valve 14 and the opening / closing handle 12a of the drain hose 20 can be inserted. Part of the through holes 123 and 124 are provided with notches 123p and 124p through which the protrusions 12p and 14p provided on the outer periphery of the opening / closing handles 12a and 14a can be inserted. The front view shapes of the through holes 123 and 124 are similar to the front view shapes of the opening / closing handles 12a and 14a, respectively.

  The two through holes 123 and 124 opened in the upper panel 25a of the hose holding member 25 (cover) are arranged at the same positions as the opening / closing handles 12a and 14a when the drain hose 20 is connected to the drain plug 14 in a normal state. Has been. The positions of the notches 123p and 124p of the through holes 123 and 124 are formed so as to be in phase with the protrusions 12p and 14p when the opening / closing handles 12a and 14a are in the closed state. Therefore, the hose holding member 25 (cover) is detachable when the drain hose 20 is connected to the drain plug 14 in a normal state and the open / close handles 12a and 14a are in the closed state.

  As described above, the hose holding member 25 (cover) is detachable only when the drain hose 20 is connected to the drain plug 14 in a normal state, and the magnet 121a constituting the detection means 120 is provided on the cover 121. Yes. Therefore, the hose holding member 25 (cover) having the magnet 121a cannot be attached unless the drain hose 20 is connected to the drain plug 14 in a normal state. If the hose holding member 25 (cover) cannot be attached, the magnet 121a can be used. Is not in a predetermined facing state with respect to the reed switch 121b, and the detection means 120 does not emit a signal, so the pressure-feed mobile toilet does not perform the draining operation.

  That is, unless the drain hose 20 is connected to the drain plug 14 in a normal state, the pressure-feed mobile toilet does not perform the drain operation. For this reason, when the drainage hose 20 is incompletely connected to the drain plug 14, water leakage does not occur even if the drainage operation is instructed on the toilet body side by mistake.

  Further, the hose holding member 25 (cover) is removable only when both the opening / closing handle 14a of the drain plug 14 and the opening / closing handle 12a of the drainage hose 20 are in the closed state, and therefore the hose holding member 25 (cover) is removed. In some cases, it is necessary to close the opening / closing handles 12a and 14a in advance. Therefore, forgetting to close the open / close handles 12a, 14a when the drain hose 20 is separated from the drain plug 14 for maintenance or the like can be prevented.

  Furthermore, since the front panel 25a, the fixing panels 25a and 21b, and the partition panel 25d constituting the hose holding member 25 (cover) are arranged so as to cover the attachment / detachment operation portion between the drain plug 14 and the drain hose 20, The attachment / detachment operation part between the stopper 14 and the drain hose 20 cannot be touched.

Further, a baffle plate 116 as a baffle member for preventing the contact preventing member 115 from coming into contact with the male joint 13 m of the water tap 13 is provided around the male joint 13 m of the water tap 13. Furthermore, a flat partition plate 24a (partition member) that partitions the joint structure on the water supply path side and the joint structure on the drainage path side is provided.

  The contact preventing member 115 includes a bottom portion 115b formed in a flange shape on the proximal end side from the distal end opening portion 12b of the male joint 12m of the drainage hose 20, and a main body formed in a cylindrical shape from the bottom portion 115b toward the distal end opening portion 12b. Part 115p. The main body 115p of the contact preventing member 115 is provided with two through holes 115w at positions facing each other, and the front end of the main body 115p can be engaged with the lower surface portion of the horizontal protrusion 14b of the drain plug 14. A pair of concave portions 115a having a substantially semicircular shape is provided.

  As shown in FIG. 10, a flat support base 24 (attachment member) is fixed to the wall surface on which the water tap 13 and the drain plug 14 are arranged, and a part of the support base 24 (attachment member) is fixed. The baffle plate 116 and the partition plate 24a (partition member) are formed by bending upright. The support base material 24 (attachment member) is a protective cover (in FIGS. 10 and 14) that covers a connection portion between the water tap 13 and the drain plug 14, the water supply hose (not shown in FIGS. 10 and 14), and the drain hose 20. Is a member for fixing).

  The baffle plate 116 extends from the support base material 24 (attachment member) to the horizontal portion 116a, the vertical portion 116b depending from the tip of the horizontal portion 116a, and the lower end of the vertical portion 116b toward the support base material 24 (attachment member).

The partition plate 24a (partition member) includes a vertical portion 24aa standing from the support base material 24 (attachment member), and a reinforcing rib 24ab formed by bending the tip of the vertical portion 24aa.

  With such a configuration, as shown in FIG. 10, since the joint structures on the faucet 13 side and the drainage hose 20 side are both male joints 12 m and 13 m, the drainage hose 20 is erroneous with respect to the faucet 13. There is no fear of being connected. Further, the male joint 12m on the drainage hose 20 side is configured to have a larger-diameter male shape than the male joint 13m on the water faucet 13 side. In addition, when the male joint 12m of the separated drainage hose 20 is reconnected, even if the male joint 12m may accidentally approach the male joint 13m of the water tap 13, the male joint 12 The 12m tip cannot contact the male joint 13m. Therefore, it is possible to prevent the water supply path from being damaged due to an erroneous operation when reconnecting the drainage hose 20 after being separated.

  Moreover, since the baffle plate 116 is provided around the male joint 13m of the water tap 13, even if the male joint 12m approaches the male joint 13m of the water tap 13 by mistake as described above, The contact preventing member 115 on the drain hose 20 side cannot contact the male joint 13 m of the water tap 13. Therefore, a reliable contact avoidance effect can be obtained by the synergistic action of the contact preventing member 115 and the baffle plate 116.

  In the present embodiment, the contact prevention member 115 has a flange-shaped bottom portion 115b and a cylindrical main body portion 115p. Accordingly, as shown in FIG. 11, when the male joint 12m of the drain hose 20 is separated from the female joint 14f of the drain plug 14, the residual sewage DW that falls from the drain plug 14 side is separated from the outer peripheral surface and bottom of the male joint 12m. It is accommodated in a portion surrounded by 115b and the inner peripheral surface of the main body 115p. For this reason, it can prevent that the residual sewage DW falls and soils a floor etc. Furthermore, since the contact preventing member 115 is configured to be detachable from the drainage hose 20, the stored residual sewage DW can be easily discarded and washed.

  Since a pair of through holes 115w are formed in the main body 115p of the contact preventing member 115, when connecting the male joint 12m of the drain hose 20 to the female joint 14f of the drain plug 14, as shown in FIG.

When the male joint 12m of the drain hose 20 is connected to the female joint 14f of the drain plug 14, the lower surface portion of the horizontal protrusion 14b of the drain plug 14 is accommodated in the recess 115a at the tip of the main body 115p of the contact prevention member 115. Therefore, the connection portion is surrounded by the main body 115p, and the protection function is excellent.

  On the other hand, since notches 116e are provided on both sides of the vertical portion 116b of the baffle plate 116, when connecting a female joint (not shown) of the water supply hose to the male joint 13m of the water tap 13, the notch 116e. The connection state can be visually confirmed through the vertical portion 116 b when the female joint (not shown) of the water supply hose is connected to the male joint 13 m of the water tap 13. Further, since a notch 116f is provided at the tip of the guard part 116c of the baffle plate 116, the guard part 116c is connected when the female joint (not shown) of the water supply hose is connected to the male joint 13m of the water tap 13. It won't interfere.

  In addition, since the partition plate 24a (partition member) is provided, the water supply path and the drainage path are clearly partitioned by the partition plate 24a (partition member), so that the drain plug 14 and the drain hose 20 can be attached and detached. It is possible to prevent the sewage from splashing and fouling the water tap 13 and the water supply hose (not shown in FIGS. 10 and 14). In addition, the partition plate 24a (partition member) is a protective cover (which is attached to cover a connection portion between the water tap 13 and the drain plug 14, the water supply hose (not explicitly shown in FIGS. 10 and 14) and the drain hose 20). (Not shown in FIGS. 10 and 14). Furthermore, a joint protection part 24e extending from the support base material 24 (attachment member) is provided above the partition plate 24a. The joint protection part 24e is arranged in parallel with a partition plate 24a (partition member) serving as a splash prevention part, which is often above the water supply joint 13m and the drainage joint 12m.

  Next, based on FIG. 12, FIG. 13, 2nd Embodiment of this invention is described. FIG. 12 is a perspective view showing a water supply / drainage joint according to the second embodiment, and FIG. 13 is a perspective view showing a part of the water supply / drainage joint shown in FIG.

In this case, when the contact prevention member 115 of the drainage hose 20 is brought into contact with the lid body 220 and separated, the lid body 20 causes the upper end surface of the recess 115a of the contact prevention member 115 provided in the drainage hose 20 to be removed. It slides as a guide surface part and closes the connection port 14c slowly, not suddenly.

  Therefore, when the drain hose 20 is separated from the drain plug 14, the lid 220 is always kept in a state where the connection port 14c (see FIG. 11) of the female joint 14f is covered. For this reason, it can prevent that the female coupling (not shown) provided in the water supply hose by the side of a water supply path touches the said connection port 14c, and is damaged. When connecting the drain hose 20 to the drain plug 14, the connection port 14 c is exposed if the lid 220 is overlaid so as to overlap the fixing portion 221 b, so that the connection operation is not hindered.

  In the above embodiment, the water tap 13 is provided with a male joint 13m, the water supply hose is provided with a female joint (not shown), the drain plug 14 is provided with a female joint 14f, and the drain hose 20 is provided with a male joint 12m. Although the structure which provided the contact prevention member 115 in the male joint 12m of this, and provided the baffle plate 116 around the water tap 13 was demonstrated, it is not limited to these structures. For example, the drain plug side can be a male joint and the drain hose side can be a female joint, and a contact preventing member for preventing contact with the female joint of the water supply hose can be provided around the male joint on the drain plug side. Even in this case, contact between the male joint of the drain plug and the female joint of the water supply hose can be prevented, and contamination of the water supply path due to erroneous work when reconnecting the drainage hose and water supply hose after separation is prevented. Can be prevented.

  Next, a third embodiment of the present invention will be described based on FIGS.

Further, the inclined surface 84 a of the joint adapter 84 is pushed into the joint adapter 83 side along the guide inclined surface 87 of the cover 85. Accordingly, the joint adapter 83 and the joint adapter 84 are brought close to each other by the guide inclined surfaces 86 and 87 of the cover 85 and are brought into close contact with each other as shown in FIG.

  The above-mentioned water supply / drainage joint is a water supply / drainage joint which forms a water supply path and a drainage path by connecting a water supply hose and a drainage hose to the water supply tap and the drainage plug provided close to each other through the joint structure. Is composed of a male joint and a female joint, and the tip of the male joint constituting the joint structure on the drainage path side is prevented from contacting the male joint or the female joint constituting the joint structure on the water supply path side. The contact prevention member is provided around the male joint on the drainage path side.

  With this configuration, the contact prevention member prevents the tip of the male joint on the drainage path side from coming into contact with the male or female joint on the water supply path side. It is possible to prevent the water supply path from being damaged due to an erroneous operation at the time of connection.

  Here, a male joint is provided on the water tap, a female joint is provided on the water supply hose, a female joint is provided on the drain plug, a male joint is provided on the drain hose, and the contact prevention member is provided on the male joint of the drain hose, A baffle plate for preventing the contact preventing member from contacting the male joint of the water faucet can be provided around the water faucet.

  With such a configuration, since the joint structure of the water faucet and the joint structure of the drain hose are both male joints, the drain hose is not erroneously connected to the faucet. Further, the contact avoidance effect is enhanced by the synergistic action of the contact preventing member and the baffle plate.

  In this case, the contact prevention member includes a bottom portion formed in a flange shape on the proximal end side from the distal end opening portion of the male joint of the drainage hose, and a main body formed in a cylindrical shape from the bottom portion toward the distal end opening portion. It is desirable to have a part. With such a configuration, when the male joint of the drain hose is separated from the female joint of the drain plug, it is possible to prevent the residual water on the drain plug side from falling and soiling the floor and the like.

  Furthermore, it is desirable to provide a partition member that partitions the joint structure on the water supply path side and the joint structure on the drainage path side. With such a configuration, since the water supply path and the drainage path are partitioned by the partition member, the sewage scatters when the drain plug and the drainage hose are attached and detached, and the water tap and the water supply hose are contaminated. Can be prevented.

  On the other hand, an openable / closable lid fixed in the vicinity of the connection port of the female joint of the drain plug and urging means for urging the lid in a direction covering the connection port may be provided. With such a configuration, when the drain hose is separated from the drain plug, the cover body covers the connection port of the female joint by the biasing means, so that the male joint and the female joint on the water supply path side are connected to the connection port. It can be prevented from being soiled by touching.

  The above-described pumping / moving toilet supply / drainage unit can be widely used as a connection means between a pumping / moving toilet used in hospital rooms, bedrooms, etc., and a water supply / drainage route.

  With such a configuration, unless the drain hose is connected to the drain plug in a normal state, the pressure-feed mobile toilet does not perform the drain operation. Therefore, if the drain plug and drain hose are incompletely connected, or if the drain hose is separated from the drain plug, the drainage will not be performed even if the drainage operation of the pressure-transfer mobile toilet is mistakenly indicated. It is not performed and water leakage can be prevented.

  Here, the detection means comprises a signal generation means for generating the signal and an operation means for operating the signal generation means, and is attached / detached only when the drain hose is connected to the drain plug in a normal state. A possible cover is provided, and the operating means can be provided on the cover. With such a configuration, the cover having the operating means cannot be attached unless the drain hose is connected to the drain plug in a normal state, and the signal generating means does not emit a signal if the cover cannot be attached. Therefore, the pumping mobile toilet does not perform the draining operation. Therefore, unless the drain hose is connected to the drain plug in a normal state, the pressure-feed mobile toilet does not perform the drain operation. For this reason, it is possible to thoroughly prevent the drainage operation when the drainage hose is incompletely connected to the drainage plug.

  Further, the detection means is constituted by a signal generation means for generating the signal and an operation means for operating the signal generation means, and an open / close valve is provided on the connection side of the drain hose with respect to the drain plug, It is also possible to provide a cover that can be detached only when in the closed state, and to provide the operating means on the cover. With such a configuration, when the opening / closing valve on the drain hose side is not closed, the cover having the operating means cannot be removed. Therefore, when removing the cover, it is necessary to close the opening / closing valve in advance. Therefore, forgetting to close the on-off valve when separating the drain hose from the drain plug for maintenance or the like can be prevented.

  On the other hand, it is desirable that the cover covers at least an attaching / detaching operation portion between the drain plug and the drain hose. With such a configuration, when the cover is attached, the attachment / detachment operation part between the drain plug and the drain hose cannot be touched. It is possible to prevent the water from separating and leaking.

  Therefore, the above-described pumping mobile toilet can be widely used by elderly persons, sick persons, and the like who need to be used in places other than toilets, such as elderly persons, hospital hospital rooms, and bedrooms of ordinary houses.

  The above-mentioned water supply / drainage joint is a water supply / drainage joint which forms a water supply path and a drainage path by connecting a water supply hose and a drainage hose to the water supply tap and the drainage plug provided close to each other through the joint structure. Is composed of a male joint and a female joint, and the tip of the male joint constituting the joint structure on the drainage path side is prevented from contacting the male joint or the female joint constituting the joint structure on the water supply path side. The contact prevention member is provided around the male joint on the drainage path side.

  With this configuration, the contact prevention member prevents the tip of the male joint on the drainage path side from coming into contact with the male or female joint on the water supply path side. It is possible to prevent the water supply path from being damaged due to an erroneous operation at the time of connection.

  Here, a male joint is provided on the water tap, a female joint is provided on the water supply hose, a female joint is provided on the drain plug, a male joint is provided on the drain hose, and the contact prevention member is provided on the male joint of the drain hose, A baffle plate for preventing the contact preventing member from contacting the male joint of the water faucet can be provided around the water faucet.

  With such a configuration, since the joint structure of the water faucet and the joint structure of the drain hose are both male joints, the drain hose is not erroneously connected to the faucet. Further, the contact avoidance effect is enhanced by the synergistic action of the contact preventing member and the baffle plate.

  In this case, the contact prevention member includes a bottom portion formed in a flange shape on the proximal end side from the distal end opening portion of the male joint of the drainage hose, and a main body formed in a cylindrical shape from the bottom portion toward the distal end opening portion. It is desirable to have a part. With such a configuration, when the male joint of the drain hose is separated from the female joint of the drain plug, it is possible to prevent the residual water on the drain plug side from falling and soiling the floor and the like.

  Furthermore, it is desirable to provide a partition member that partitions the joint structure on the water supply path side and the joint structure on the drainage path side. With such a configuration, since the water supply path and the drainage path are partitioned by the partition member, the sewage scatters when the drain plug and the drainage hose are attached and detached, and the water tap and the water supply hose are contaminated. Can be prevented.

  On the other hand, an openable / closable lid fixed in the vicinity of the connection port of the female joint of the drain plug and urging means for urging the lid in a direction covering the connection port may be provided. With such a configuration, when the drain hose is separated from the drain plug, the cover body covers the connection port of the female joint by the biasing means, so that the male joint and the female joint on the water supply path side are connected to the connection port. It can be prevented from being soiled by touching.

  Therefore, the above-described water supply / drainage joint can be widely used as a connection structure for a water supply / drainage path of a pressure-transfer mobile toilet in a hospital, a nursing facility, a general house, or the like.
