Description

  The present invention relates to a mobile toilet that is movable on a floor surface.

  Conventionally, toilets are installed in toilet spaces that are designed and constructed in advance, and appropriate slopes and diameters of water pipes are determined depending on the location of the toilet space, and sewage containing sewage and urine (sewage) is sewered. It was configured to discharge into the grid. On the other hand, mobile toilets have been proposed in order to cope with elderly people, sick people, and the like who need to be used in places other than the toilet space.

  In such a mobile toilet, the water supply pipe and the drainage pipe are configured to be detachable from the water supply connection part and the drainage connection part provided in the building frame. If a detachable joint is used between the water supply pipe and the drainage pipe and the water supply connection part and the drainage connection part in order to ensure such detachability, the mobile toilet will supply water rather than the full length of the water supply pipe and the drainage pipe. The problem that a water supply pipe and a drainage pipe will come off by moving to a place away from a connection part and a drainage connection part arises.

  Therefore, in Patent Document 1 below, there is provided movement restriction means for restricting the toilet body of the mobile toilet so that it does not move out of a predetermined range.

JP 2014-58824 A

  As shown in FIG. 2 and the like of Patent Document 1, the moving range of the mobile toilet is regulated by the length of the wire that connects the mobile toilet and the building frame. Since the length of the wire is set to be shorter than the length of the water supply pipe and the drain pipe, an external force in the pulling direction does not act on the water supply pipe and the drain pipe in a normal use situation.

  However, since the wire as the movement restricting means and the water supply pipe and the drain pipe are provided as separate and independent ones, for example, a person who has passed the vicinity of the mobile toilet hangs his / her foot on the water supply pipe and the drain pipe It is not taken into consideration when it is closed.

  The present invention has been made in view of such problems, and the purpose thereof is a mobile toilet that is movable on the floor surface, even when an external force is directly applied to a water supply pipe and a drain pipe. An object of the present invention is to provide a mobile toilet that can prevent the water supply pipe and the drainage pipe from coming off from the water supply connection part and the drainage connection part on the building frame side.

  In order to solve the above-mentioned problems, a mobile toilet according to the present invention is a mobile toilet that is movable on a floor surface, and is provided in a building housing for supplying flush water to the toilet body and the toilet body. A water supply pipe connected to the water supply connection part, a drain pipe connected to a drainage connection part provided in the building cabinet to discharge sewage from the toilet body, and a moving mechanism for moving the toilet body, Regulating means for regulating the movement range of the toilet body. The regulating means is provided closer to the water supply connection part and the drainage connection part than the central part of the water supply pipe and the drainage pipe.

  According to the present invention, the regulating means is provided on the side of the water supply connection part and the drainage connection part rather than the central part of the water supply pipe and the drainage pipe. Even so, the regulating means receives the external force. Therefore, even if an external force acts on the water supply pipe and the drainage pipe between the toilet body from the regulating means, the external force is not directly transmitted to the part where the water supply pipe and the drainage pipe and the water supply connection part and the drainage connection part are connected. It can suppress that a water supply pipe and a drainage pipe come off from a water supply connection part and a drainage connection part.

  Further, in the mobile toilet according to the present invention, the restricting means does not change the relative positional relationship between the holding point on the side of the water supply connection part and the drainage connection part and the building frame from the central part of the water supply pipe and the drainage pipe. It is also preferable to be provided.

  In this preferable aspect, since the regulating means is provided so as not to change the relative positional relationship between the holding point and the building frame, even if an external force is applied to the water supply pipe and the drain pipe on the toilet body side from the holding point. The external force can be more reliably suppressed from being directly transmitted to a portion where the water supply pipe and the drainage pipe are connected to the water supply connection part and the drainage connection part.

  In the mobile toilet according to the present invention, the regulating means holds the holding points of the water supply pipes and the drainage pipes and fixes them to the building frame, so that the water supply connection part and the drainage connection part side of the water supply pipes and the drainage pipes relieve stress. It is also preferable to have a holding and fixing part that forms a water supply pipe part and a stress relaxation drain pipe part.

  In this preferable aspect, since the holding fixing part holds the holding point of the water supply pipe and the drainage pipe and fixes it to the building frame, the water supply pipe and the drainage pipe are directly or indirectly fixed to the building frame at the holding point. Thus, the relative positional relationship between the holding point and the building frame can be fixed so as not to change reliably.

  Further, in the mobile toilet according to the present invention, the restricting means covers the water supply connection portion and the drainage connection portion side from the holding point of the water supply tube and the drainage pipe to form a concealed water supply pipe portion and a concealed drainage pipe portion, which cannot be gripped by the user. It is also preferable to have a concealing part to be made.

  In this preferable aspect, since the concealment part covers the water supply connection part and the drainage connection part side from the holding point of the water supply pipe and the drainage pipe, the concealed water supply pipe part and the concealed drainage pipe part that cannot be gripped by the user can be formed. The water supply pipe and drain pipe on the side of the water supply connection part and drainage connection part are concealed from the holding point, and are not gripped by the user and are not subjected to external force, and the external force is supplied to the water supply pipe and drain pipe, the water supply connection part and the drainage connection part. Direct transmission to the connected part can be more reliably suppressed.

  Further, in the mobile toilet according to the present invention, the holding and fixing portion has a length of the stress relaxation water supply pipe portion and the stress relaxation drainage pipe portion that is a straight line from the holding point of the water supply pipe and the drainage pipe to the water supply connection portion and the drainage connection portion. It is also preferable to be provided so as to be longer than the distance.

  In this preferred embodiment, the length of the stress relaxation water supply pipe part and the stress relaxation drain pipe part is longer than the linear distance from the holding point of the water supply pipe and the drain pipe to the water supply connection part and the drain connection part. Even when the building housing is separated, it is possible to suppress the external force from being transmitted to a portion where the water supply pipe and the drain pipe are connected to the water supply connection portion and the drain connection portion.

  In the mobile toilet according to the present invention, it is also preferable that the holding and fixing portion is provided on the wall surface such that the stress relaxation water supply pipe portion and the stress relaxation drain pipe portion are arranged along the wall surface of the building frame.

  In this preferred embodiment, the stress relaxation water supply pipe part and the stress relaxation drain pipe part are arranged along the wall surface of the building frame. For example, the user puts his feet on the stress relaxation water supply pipe part and the stress relaxation drain pipe part. Thus, it is possible to suppress an inadvertent external force from being transmitted to a portion where the water supply pipe and the drainage pipe are connected to the water supply connection part and the drainage connection part.

  According to the present invention, it is a mobile toilet that is movable on the floor surface, and even when an external force is directly applied to the water supply pipe and the drainage pipe, the water supply pipe and the drainage pipe are connected to the water supply connection part on the building frame side. In addition, it is possible to provide a mobile toilet that can be prevented from coming off from the drainage connection part.

  Hereinafter, embodiments of the present 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.

  First, a mobile toilet according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. Although the present invention is not limited to a toilet bowl and is a technical idea applied to a toilet bowl that can move on a floor surface, in the present embodiment, a toilet bowl will be described as an example. FIG. 1 is a view showing an appearance of a mobile toilet MS according to an embodiment of the present invention. FIG. 2 is a cross-sectional view schematically showing the structure of the mobile toilet MS shown in FIG.

  As shown in FIG. 1, the mobile toilet MS is a mobile toilet installed on the floor F of a house.

  The end of drainage pipe 300 and water supply pipe 400 is connected to this mobile toilet MS. The drainage pipe 300 has flexibility, and is connected to a water supply / drainage outlet 500 provided on the wall surface W of the house at a drainage connection part 310 at the other end. Similarly, the water supply pipe 400 is flexible, and is connected to the water supply / drain outlet 500 at the water supply connection part 410 at the other end. The drainage connection part 310 and the water supply connection part 410 are detachable from the water supply / drainage outlet 500. In the present embodiment, a holding cover 60 (corresponding to the restricting means, the holding and fixing portion, and the concealing portion of the present invention) is provided so as to cover the drainage connecting portion 310 and the water supply connecting portion 410.

  The mobile toilet MS receives the waste excreted by the user with the bowl portion 111 and then pumps the waste through the drainage pipe 300. The drainage pipe 300 communicates with the sewage pipe through the drainage connection part 310 and the water supply / drainage outlet 500, and the filth sent by pressure is discharged to the sewage pipe.

  In addition, water is supplied to the bowl portion 111 through the water supply pipe 400 for cleaning the bowl portion 111 that has received the filth. The water supply pipe 400 communicates with the water pipe via the water supply connection part 410 and the water supply / drain outlet 500, and water is supplied from the water pipe.

  The water supply / drain outlet 500 is provided on the wall surfaces W of a plurality of rooms in the house. Therefore, the mobile toilet MS can be used in each room by moving the mobile toilet MS in the house and connecting the drainage connection part 310 and the water supply connection part 410 to the water supply / drainage outlet 500 of each room. It can be.

  As shown in FIG. 2, the mobile toilet MS includes a toilet body 100, wheels 200 (movement mechanism), and a holding cover 60. The toilet body 100 includes a bowl portion 111, a discharge channel 113, a processing device 140, and a cleaning water supply device 150.

  The bowl part 111 is formed in the shape of a mortar that is open at the top, and temporarily receives the waste discharged by the user. A rim portion 112 having a substantially horizontal surface is formed at the upper end portion of the bowl portion 111, and a toilet seat 130 is placed on the rim portion 112. The user puts his / her buttocks on the toilet seat 130 (sits down) and performs excretion.

  One end of the discharge channel 113 is connected to the lower end of the bowl 111. The discharge channel 113 has a trap 114 and a downstream channel 115. The trap 114 is formed such that its downstream end extends upward, so that water can be stored therein. Further, the downstream flow path 115 extends downward from the downstream end portion of the trap 114. Thereby, the water stored in the trap 114 functions as sealed water that prevents the backflow of gas from the downstream flow path 115 to the bowl portion 111 side.

  The processing device 140 agitates and discharges the waste and washing water discharged from the toilet body 100 (hereinafter, both are collectively referred to as “sewage”) to the sewer pipe in a state where the fluidity is improved. Device. The processing device 140 includes a storage tank 141 and a pulsator 143.

  The storage tank 141 is a container formed in a substantially cylindrical shape for storing sewage inside, and the downstream flow path 115 of the discharge flow path 113 is connected to the front side surface thereof. Further, a drainage pipe 300 is connected to the rear side surface of the storage tank 141. Thereby, the bowl part 111, the discharge flow path 113, the storage tank 141, and the drainage piping 300 are in the state which the inside connected.

  The pulsator 143 is fixed to the lower end of a rod-like shaft 142 disposed along the central axis of the storage tank 141 and is disposed near the bottom surface inside the storage tank 141. The upper end of the shaft 142 is fixed to the output shaft of the motor arranged at the upper part of the storage tank 141.

  When the motor operates, the shaft 142 rotates around its central axis, and the pulsator 143 rotates. Due to the rotation of the pulsator 143, the sewage stored in the storage tank 141 is agitated, and the sewage (excrement) is mixed with the wash water while being crushed, so that the fluidity of the sewage is enhanced.

  The sewage whose fluidity is enhanced by the pulsator 143 is pumped from the storage tank 141 to the drain pipe 300. This sewage is discharged to the sewer pipe through the drainage pipe 300, the drainage connection part 310 and the water supply / drainage outlet 500.

  The cleaning water supply device 150 is a device that supplies water for cleaning (cleaning water) to the bowl portion 111. The cleaning water supply device 150 has a tank 151 and an internal flow path 154.

  The tank 151 is a container that stores water therein, and is provided behind the bowl portion 111. A water supply pipe 400 is connected to the rear side surface of the tank 151. Thereby, the water supplied from the water pipe through the water supply / drain outlet 500, the water supply connection part 410, and the water supply pipe 400 flows into the tank 151.

  The internal flow path 154 is a flow path for supplying water stored in the tank 151 to the bowl portion 111. The internal flow path 154 has one end connected to the front side surface of the tank 151 and the other end connected to the upper portion of the bowl portion 111. A valve 155 that opens and closes the internal flow path 154 is provided between the tank 151 and the bowl portion 111. When the valve 155 opens the internal flow path 154, the water inside the tank 151 flows into the internal flow path 154 and is supplied to the upper portion of the bowl portion 111. This water flows downward on the surface of the bowl part 111, whereby the bowl part 111 after use is washed.

  Here, the tank 151 is provided with an air inlet 152. The air inlet 152 is a circular hole that penetrates the tank 151 and communicates the inside and the outside.

  When the water inside the tank 151 is discharged outside through the internal flow path 154, the inside of the tank 151 becomes negative pressure, and air is introduced into the tank 151 through the air inlet 152. That is, air is introduced from the outside so as to replace the water stored in the tank 151. On the other hand, when water is supplied to the tank 151 via the water supply pipe 400, the inside of the tank 151 becomes positive pressure due to the inflowing water, and the air is discharged to the outside of the tank 151 via the air inlet 152. That is, air is discharged to the outside so as to replace the water supplied to the inside of the tank 151.

  The air inlet 152 is a portion closer to the front of the tank 151, and only one air inlet 152 is provided above the surface of the water stored in the tank 151. A portion closer to the rear of the tank 151 is shielded so that air is not introduced from the outside.

  An air introduction tube 153 is fixed to the air introduction port 152 in a state where it is inserted. The air introduction tube 153 is formed in a cylindrical shape along the outer peripheral edge of the air introduction port 152, and has an outer tube 153 a that protrudes outward from the tank 151 and an inner tube 153 b that protrudes toward the inside of the tank 151. And consist of

  Two wheels 200 are provided in the lower rear part of the toilet body 100 (in FIG. 2, only the wheel 200 on the near side is illustrated). The toilet body 100 is placed on the floor F by being supported from below by the two wheels 200 and the legs 170 provided in the lower front part. With the support at these three points, the rim portion 112 of the toilet body 100 becomes substantially horizontal, and the user can sit on the toilet seat 130 and excrete. The front lower part of the toilet body 100 is supported by the legs 170 so as not to move with respect to the floor surface F, so that the user can excrete in a stable posture.

  Further, a protrusion 180 (regulating means) is provided at the lower rear portion of the toilet body 100. The protrusion 180 is provided so as to protrude downward from the rear side of the wheel 200.

  In the present embodiment, a holding cover 60 is provided as a restricting means for restricting the movement range of the toilet body 100. The holding cover 60 is provided so as to hold the water supply connection part 410 and the drainage connection part 310 side from the central part of the water supply pipe 400 and the drainage pipe 300. More specifically, the holding cover 60 is relative to the holding point on the side of the water supply connection part 410 and the drainage connection part 310 and the building frame (wall surface W, floor surface F) rather than the central part of the water supply pipe 400 and the drainage pipe 300. The water supply pipe 400 and the drainage pipe 300 are held so as not to change the general positional relationship.

  The holding cover 60 is fixed to the wall surface W and has a holding and fixing portion 61 and a holding and fixing portion 62. The holding and fixing part 62 is provided at a holding point closer to the water supply connecting part 410 than the central part of the water supply pipe 400, and fixes the water supply pipe 400 to the holding cover 60. The holding and fixing part 61 is provided at a holding point closer to the drainage connection part 310 than the central part of the drainage pipe 300, and fixes the drainage pipe 300 to the holding cover 60.

  Accordingly, the water supply pipe 400 between the holding and fixing part 62 and the water supply connection part 410 is a stress relaxation water supply pipe part 400a. Further, the drainage pipe 300 from the holding and fixing part 61 to the drainage connection part 310 is a stress relaxation drainage pipe part 300a. In the case of the present embodiment, the stress-relieving water supply pipe portion 400a and the stress-relieving drainage pipe portion 300a are covered with the holding cover 60 and configured so as not to be gripped by the user. It also functions as a concealed drain pipe.

  The holding and fixing portion 62 holds the water supply pipe 400 so that the length of the stress relaxation water supply pipe portion 400 a is longer than the linear distance from the holding and fixing portion 62 to the water supply connection portion 410. The holding and fixing part 61 holds the drainage pipe 300 so that the length of the stress relaxation drainage pipe part 300 a is longer than the linear distance from the holding and fixing part 61 to the drainage connection part 310.

FIG. 3A is a diagram illustrating normal states of the mobile toilet MS, the water supply pipe 400, and the drain pipe 300 described in FIG. 3B shows a state where an external force is applied to the water supply pipe 400 and the drainage pipe 300, and FIG. 3C shows the holding cover 60 when an external force is applied to the water supply pipe 400 and the drainage pipe 300. It is a figure which shows this external force.

  As shown in FIG. 3, since the holding and fixing portions 61 and 62 are provided closer to the water supply connection portion 410 and the drainage connection portion 310 than the central portion of the water supply piping 400 and the drainage piping 300, Even if the external force F acts on the water supply pipe 400 and the drain pipe 300 between the toilet main bodies 100, the holding cover 60 and the holding fixing portions 61 and 62 receive the external force. Therefore, even if an external force F acts on the water supply pipe 400 and the drainage pipe 300 between the holding cover 60 and the holding and fixing parts 61 and 62 and the toilet body 100, the water supply pipe 400 and the drainage pipe 300, the water supply connection part 410, and the drainage connection Since the external force is not directly transmitted to the portion connected to the portion 310, it is possible to prevent the water supply pipe 400 and the drainage pipe 300 from coming off from the water supply connection portion 410 and the drainage connection portion 310.

  In the present embodiment, the holding cover 60 and the holding and fixing portions 61 and 62 are provided so as not to change the relative positional relationship between the holding point (the point held by the holding and fixing portions 61 and 62) and the building frame. Therefore, even if an external force F is applied to the water supply pipe 400 and the drainage pipe 300 on the toilet body 100 side from the holding point, the external force F is applied to the water supply pipe 400 and the drainage pipe 300, the water supply connection part 410 and the drainage connection part 310. Direct transmission to the connected part can be more reliably suppressed.

  In the present embodiment, the holding and fixing parts 61 and 62 hold the holding points of the water supply pipe 400 and the drainage pipe 300, and the holding and fixing parts 61 and 62 are fixed to the wall surface W by the holding cover 60. In this way, the water supply pipe 400 and the drain pipe 300 are indirectly fixed to the building frame at the holding point, and are fixed so that the relative positional relationship between the holding point and the building frame is not changed reliably. Can do.

  In the present embodiment, since the holding cover 60 that functions as a concealing unit covers the water supply connection unit 410 and the drainage connection unit 310 side from the holding points of the water supply pipe 400 and the drainage pipe 300, the concealed water supply pipe unit that cannot be gripped by the user and The stress relaxation water supply pipe portion 400a and the stress relaxation drainage pipe portion 300a that function as a concealed drainage pipe portion can be formed. The stress relaxation water supply pipe portion 400a and the stress relaxation drainage pipe portion 300a on the side of the water supply connection portion 410 and the drainage connection portion 310 are concealed from the holding point so that the external force is not gripped and applied by the user and the external force is applied to the stress relaxation water supply pipe. Direct transmission to the part where the part 400a and the stress relaxation drain pipe part 300a, the water supply connection part 410, and the drainage connection part 310 are connected can be suppressed more reliably.

  In this embodiment, the length of the stress relaxation water supply pipe portion 400a and the stress relaxation drainage pipe portion 300a is changed from the holding fixing portions 61 and 62 which are holding points of the water supply pipe 400 and the drainage pipe 300 to the water supply connection portion 410 and the drainage connection portion. Since it is longer than the linear distance up to 310, even if a very large external force F is applied and the holding and fixing parts 61 and 62 are separated from the wall surface W, the stress relaxation water supply pipe part 400a and the stress relaxation drain pipe part 300a It can suppress that external force is transmitted to the part where the water supply connection part 410 and the drainage connection part 310 are connected.

  Moreover, in this embodiment, it is also preferable that the holding and fixing portion is provided on the wall surface such that the stress relaxation water supply pipe portion and the stress relaxation drain pipe portion are arranged along the wall surface of the building frame. A modification as a preferable example will be described with reference to FIGS.

  As shown in FIG. 4, the holding and fixing unit 63 directly fixes the water supply pipe 400 and the drain pipe 300 to the wall surface W at the holding point. In this aspect, since the stress relaxation water supply pipe part 400a and the stress relaxation drain pipe part 300a are arranged along the wall surface W of the building frame, for example, the user attaches a foot to the stress relaxation water supply pipe part 400a and the stress relaxation drain pipe part 300a. For example, it is possible to prevent an inadvertent external force from being transmitted to a portion where the water supply pipe 400 and the drainage pipe 300 are connected to the water supply connection portion 410 and the drainage connection portion 310.

  Moreover, in this aspect, since the holding fixing part 63 holds the holding point of the water supply pipe 400 and the drainage pipe 300 and fixes it to the wall surface W of the building frame, the water supply pipe 400 and the drainage pipe 300 are directly attached to the building frame at the holding point. It can be fixed so that the relative positional relationship between the holding point and the building frame is not changed reliably.
