Description

This disclosure relates to a toilet device.

Patent Document 1 discloses a flush toilet device for nursing care. The flush toilet bowl of this flush toilet device is stored in a toilet storage room when not in use, and can be moved from the toilet storage room to a toilet installation room when in use. The upstream end of a flexible drain pipe and the downstream end of a flexible water supply pipe are connected to the flush toilet bowl. The drain pipe and water supply pipe have extra length to allow them to flexibly deform as the flush toilet bowl moves.

Utility Model Registration No. 3076664

The cabinet 10 includes an equipment storage section 11, a support section 23, a washstand 24, and a rotating shaft 27. The equipment storage section 11 includes a toilet storage section 12, an attachment section 20, and a back storage section 21.

The toilet storage section 12 is a rectangular box-shaped opening on the top and bottom, and is installed on the floor surface F. The rear area on the left side of the toilet storage section 12 is also open in a manner that communicates with the openings on both the top and bottom. In this embodiment 1, the front of the toilet storage section 12 is defined as the front section 12F. In the area of the front section 12F of the toilet storage section 12 excluding the left end, an opening 13 is formed that opens the internal space of the toilet storage section 12 to the front outside of the equipment storage section 11. A toilet storage space 14 for accommodating a toilet device 41 is provided inside the toilet storage section 12.

The toilet storage section 12 is provided with a door 15 for opening and closing the opening 13. The door 15 is composed of a folding door having a hanging panel 16 and a door end panel 17. The hanging panel is supported on the right edge of the opening 13. In the process of opening the door 15 from a closed state, the two panels 16, 17 are displaced so that they overlap with their inner faces facing each other. When the door 15 is open, it protrudes forward from the right edge of the opening 13.

The mounting part 20 has a rectangular box shape with an open bottom, and is placed on top of the toilet storage part 12. The bottom surface of the mounting part 20 is connected to the top surface of the toilet storage part 12, and the space inside the toilet storage part 12 and the space inside the mounting part 20 are connected to form a single space. The rear area on the left side of the mounting part 20 is open in a form that communicates with the opening on the bottom surface of the mounting part 20 and the opening on the left side of the toilet storage part 12.

In a plan view of the cabinet 10 seen from above, the toilet storage section 12 and the mounting section 20 have the same shape, the toilet storage section 12 and the mounting section 20 have the same depth dimension in the front-to-back direction, and the toilet storage section 12 and the mounting section 20 have the same width dimension in the left-to-right direction. In a plan view, the mounting section 20 is superimposed directly above the toilet storage section 12. The front section 12F of the toilet storage section 12 and the front section 20F of the mounting section 20 are connected flush. The right side surface of the mounting section 20 and the right side surface of the toilet storage section 12 are connected flush. The back surface of the mounting section 20 and the back surface of the toilet storage section 12 are connected flush.

The rear storage section 21 is a rectangular box-shaped section with an open bottom, and is arranged to be lined up on the left side of the toilet storage section 12 and the mounting section 20. The top end surface of the rear storage section 21 is at the same height as the top end surface of the mounting section 20. The front surface 21F of the rear storage section 21 is located rearward of the front surface 12F of the toilet storage section 12 and the front surface 20F of the mounting section 20. The right side of the rear storage section 21 is open and communicates with the openings on the left sides of the toilet storage section 12 and the mounting section 20. Therefore, the space within the toilet storage section 12, the space within the mounting section 20, and the space within the rear storage section 21 are communicated to form a single space.

The support section 23 has a rectangular box shape and is installed on the floor surface F. The support section 23 is adjacent to the front side of the rear storage section 21 and is arranged adjacent to the left side of the toilet storage section 12 and the mounting section 20. The upper end of the support section 23 is lower in height than the upper end of the mounting section 20 and the upper end of the rear storage section 21. A washbasin 24 and a faucet 25 are attached to the upper surface of the support section 23.

The rotating shaft 27 is disposed in the equipment storage section 11 with its axis facing in a vertical direction perpendicular to the floor surface F. The lower end of the rotating shaft 27 is fixed to the floor surface F, and the upper end of the rotating shaft 27 is fixed to the upper plate of the mounting section 20. The rotating shaft 27 is the center of the arc-shaped movement trajectory that the portable toilet 40 described below follows when it moves between the use position (see Figures 4 to 7) and the storage position (see Figures 2 and 3).

The toilet device 41 of the portable toilet 40 comprises a toilet body 42 and a drainage device 50. The toilet body 42 comprises a toilet body 43 having a toilet bowl (not shown), a toilet seat 44 placed on the upper surface of the toilet body 43, and an equipment storage section 45. The equipment storage section 45 stores functional devices (not shown) for improving the usability of the toilet body 42. The functional devices include a private part cleaning device, a toilet bowl cleaning device, a sound dummy device, a toilet seat opening and closing device, a toilet seat heating device, a warm air device, and a deodorizing device.

A water supply connection 46 for supplying water to the toilet body 42 is provided on the rear surface of the toilet bowl body 43 in the toilet body 42. The water supply connection 46 is located in the vertical center of the toilet body 42. In the horizontal direction, the water supply connection 46 is located to the left of the center of the toilet body 42, that is, closer to the rotation axis 27 than the center of the toilet body 42. The downstream end of a flexible water supply hose 47 extending from the floor surface F is connected to the water supply connection 46.

A drainage connector 48 for connecting to the drainage device 50 is provided on the rear surface of the toilet body 43, facing the drainage device 50. The drainage connector 48 is located in the left-right center of the toilet body 42, and is located lower than the up-down center of the toilet body 42. The drainage device 50 is a device that drains the toilet body 42 using a pump function. A drainage pipe 49, which is a drainage path for discharging waste and the like from the toilet body 42, is installed between the left-right center of the front surface of the drainage device 50 and the drainage connector 48 of the toilet body 42.

The top surface of the drainage device 50 is provided with a drainage toilet side connection part 51 and a ventilated toilet side connection part 52. The drainage toilet side connection part 51 and the ventilated toilet side connection part 52 are located in the left-right center of the drainage device 50. Since the height of the top surface of the drainage device 50 is lower than the top surface of the toilet body 42, the height of the drainage toilet side connection part 51 and the ventilated toilet side connection part 52 corresponds to the height of the vertical center of the toilet body 42.

The cart 55 of the portable toilet 40 has a base member 56 on which the toilet device 41 is placed, four casters 57 attached to the base member 56, and one bearing portion 58 provided on the base member 56. The toilet body 42 is placed and fixed to the front end region of the base member 56. The drainage device 50 is placed and fixed to the rear end of the base member 56. The cart 55 can move horizontally on the floor surface F by the casters 57, and moves the toilet device 41 as a unit between the use position and the storage position.

The bearing portion 58 is disposed behind the rear end 42R of the toilet body 42 and in front of the front end 50F of the drainage device 50. The mounting position of the bearing portion 58 in the left-right direction is to the left of the left end of the toilet body 42. The rotating shaft 27 passes through the bearing portion 58. The portable toilet 40 moves between the storage position and the usage position while tracing a quarter-circular arc trajectory on the floor surface F with the rotating shaft 27 as the center.

In a plan view, the position where the portable toilet 40 is stored within the toilet storage section 12 is defined as the storage position. The position where the toilet body 42 of the portable toilet 40 is exposed to the front outside of the toilet storage section 12 is defined as the usage position. When the door 15 of the toilet storage section 12 is opened, the opening 13 is opened, so that the portable toilet 40 can be stored within the toilet storage section 12 and the portable toilet 40 within the toilet storage section 12 can be moved to the usage position.

When the toilet device 41 is changed in orientation between the storage position and the use position by the rotation shaft 27, the toilet body 43 moves in a rotational manner within a horizontal plane. The installation position of the rotation shaft 27 in the depth direction of the toilet storage section 12 is close to the front section 12F. The installation position of the rotation shaft 27 in the width direction of the toilet storage section 12 is on the left side closer to the washbasin 24 than the center of the width direction of the toilet storage section 12.

When the portable toilet 40 is stored in the storage position, the front-to-rear direction of the toilet device 41 is parallel to the front surface 12F and width direction of the toilet storage section 12. The portable toilet 40 in the storage position can be moved to the usage position by rotating it horizontally by 90° in a clockwise direction in a plan view. When the portable toilet 40 is in the usage position, the front-to-rear direction of the toilet device 41 is perpendicular to the front surface 12F of the toilet storage section 12.

The internal space of the area of the rear storage section 21 above the toilet storage section 12 and the internal space of the mounting section 20 form a piping space 60 for arranging a drainage pipe 61 and a ventilation pipe 62. In addition to the drainage pipe 61 and the ventilation pipe 62, the piping space 60 also accommodates a part of a drainage hose 66 and a ventilation hose 68. The piping space 60 is secured in an area above the toilet storage section 12. Therefore, the drainage pipe 61 and the ventilation pipe 62 do not interfere with the mobile toilet 40 when the mobile toilet 40 is moved to the storage position.

The drainage pipe 61 is fixed horizontally while passing through the partition walls separating multiple hospital rooms or living spaces, and is arranged along the rear wall of the equipment storage section 11. One drainage pipe 61 is shared by multiple toilet devices 41 installed individually in multiple hospital rooms or living spaces, and functions as a shared path for discharging waste from the multiple toilet devices 41.

Like the drainage pipes 61, the ventilation pipes 62 are fixed horizontally while passing through the partition walls separating multiple hospital rooms or living spaces, and are arranged along the rear wall of the equipment storage section 11. One ventilation pipe 62 is shared by multiple drainage devices 50 installed individually in multiple hospital rooms or living spaces, and allows the pump functions of the multiple drainage devices 50 to function.

A reverse-prevention pipe 63 that protrudes diagonally upward and to the left from the drainage pipe 61 is connected to the portion of the drainage pipe 61 that is stored in the rear storage section 21. A ball valve 64 is connected in a suspended state to the upper end of the reverse-prevention pipe 63. A drainage pipe side connection part 65 is provided to the lower end of the ball valve 64. The downstream end of a flexible drainage hose 66 is connected to the drainage pipe side connection part 65. The upstream end of the drainage hose 66 is connected to the drainage toilet side connection part 51 of the drainage device 50.

The drain hose 66 is hung between the drain pipe side connection part 65 and the drain toilet side connection part 51 in a curved state so that it bulges downward due to its own weight. Because the drain pipe side connection part 65 is located higher than the drain toilet side connection part 51, most of the weight of the drain hose 66 is supported by the drain pipe side connection part 65.

The ventilation pipe 62 has a ventilation pipe side connection part 67 at a position to the right of the drainage pipe side connection part 65 in the left-right direction. One end of a flexible ventilation hose 68 is connected to the ventilation pipe side connection part 67. The other end of the ventilation hose 68 is connected to the ventilation toilet side connection part 52 of the drainage device 50.

The ventilation hose 68 is hung between the ventilation pipe side connection part 67 and the ventilator side connection part 52 in a curved state so that it bulges downward due to its own weight. Because the ventilation pipe side connection part 67 is located higher than the ventilator side connection part 52, most of the weight of the ventilation hose 68 is supported by the ventilation pipe side connection part 67.

The drainage device 50, to which the drainage hose 66 and the ventilation hose 68 are connected, moves between a use position and a storage position. The horizontal distance between the drainage pipe side connection part 65 and the drainage toilet side connection part 51 is longest when the mobile toilet 40 is in the use position. The length of the drainage hose 66 is set so that the drainage hose 66 does not slacken between the drainage pipe side connection part 65 and the drainage toilet side connection part 51 when the mobile toilet 40 is in the use position.

The horizontal distance between the drain pipe side connection part 65 and the drain toilet side connection part 51 is shortest when the portable toilet 40 is in the stored position. The length of the drain hose 66 is set so that no part of the drain hose 66 comes into contact with the floor surface F when the portable toilet 40 is in the stored position. In other words, the length is set so that the underside of the lowest part of the drain hose 66 is higher than the floor surface F.

The horizontal distance between the ventilation pipe side connection part 67 and the ventilation toilet side connection part 52 is longest when the portable toilet 40 is in the use position. The length of the ventilation hose 68 is set to a length that allows some slack so that the ventilation hose 68 is not pulled between the ventilation pipe side connection part 67 and the ventilation toilet side connection part 52 when the portable toilet 40 is in the use position.

The horizontal distance between the ventilation pipe side connection part 67 and the ventilation toilet side connection part 52 is shortest when the portable toilet 40 is in the storage position. The length of the ventilation hose 68 is set so that no part of the ventilation hose 68 comes into contact with the floor surface F when the portable toilet 40 is in the storage position. In other words, the length is set so that the underside of the lowest part of the ventilation hose 68 is higher than the floor surface F.

When the mobile toilet 40 is in the use position, the drainage toilet side connection part 51 and the ventilated toilet side connection part 52 of the drainage device 50 are located behind the rotation axis 27 and in front of the drainage pipe side connection part 65 and the ventilated pipe side connection part 67. When the mobile toilet 40 moves from the use position to the storage position, the drainage device 50 rotates 90° counterclockwise in a plan view of the cabinet 10 viewed from above. Even when the mobile toilet 40 is in the storage position, the drainage toilet side connection part 51 and the ventilated toilet side connection part 52 are located behind the rotation axis 27 and in front of the drainage pipe side connection part 65 and the ventilated pipe side connection part 67.

When the portable toilet 40 moves between the use position and the storage position, the path along which the drain toilet side connection part 51 and the vent toilet side connection part 52 move is limited to the area behind the rotation shaft 27 in the front-to-rear direction of the cabinet 10. Therefore, the drain hose 66 and the vent hose 68 do not come into contact with the rotation shaft 27 when the portable toilet 40 moves between the use position and the storage position.

The toilet device 1 of this embodiment 1 includes a drainage pipe 61 and a ventilation pipe 62, which are fixed pipes that are fixedly installed, a toilet device 41 that is movable on a floor surface F, a flexible drainage hose 66, and a flexible ventilation hose 68. The drainage pipe 61 is provided with a drainage pipe side connection part 65, and the ventilation pipe 62 is provided with a ventilation pipe side connection part 67. The toilet device 41 is provided with a toilet drain side connection part 51 and a toilet ventilation side connection part 52.

The drainage hose 66 is provided between the drainage pipe side connection part 65 and the drainage toilet side connection part 51, and connects the drainage pipe 61 and the toilet device 41. Fluids such as sewage are transferred between the drainage pipe 61 and the toilet device 41 by passing through the drainage hose 66. The drainage toilet side connection part 51 is located at a lower position than the drainage pipe side connection part 65. The ventilation hose 68 is provided between the ventilation pipe side connection part 67 and the ventilation toilet side connection part 52, and connects the ventilation pipe 62 and the toilet device 41. Air is transferred between the ventilation pipe 62 and the toilet device 41 by passing through the ventilation hose 68. The ventilation toilet side connection part 52 is located at a lower position than the ventilation pipe side connection part 67.

The drain hose 66 has excess length so that it can deform as the toilet device 41 moves. However, because the drain pipe side connection part 65 is located higher than the toilet drain side connection part 51, the drain hose 66 can be prevented from sliding against the floor surface F. The ventilation hose 68 also has excess length so that it can deform as the toilet device 41 moves. However, because the ventilation pipe side connection part 67 is located higher than the toilet drain side connection part 52, the ventilation hose 68 can be prevented from sliding against the floor surface F.

If the drain hose 66 has a long excess length, it is possible that part of the drain hose 66 will come into contact with the floor surface F. However, since the drain hose 66 is supported at a position higher than the floor surface F by the drain pipe side connection part 65, the weight of the drain hose 66 acting on the floor surface F when the drain hose 66 slides against the floor surface F is reduced. This reduces wear on the drain hose 66. Similarly, wear on the ventilation hose 68 caused by sliding against the floor surface F can be reduced.

The overall length of the drain hose 66 is set to a dimension that keeps the drain hose 66 out of contact with the floor surface F throughout the entire process (i.e., at least part of the movement process) of the toilet device 41 moving between the storage position and the use position. This reduces the sliding resistance that occurs between the drain hose 66 and the floor surface F compared to when the drain hose 66 is always in contact with the floor surface F during the movement of the toilet device 41. As with the drain hose 66, the sliding resistance that occurs between the ventilation hose 68 and the floor surface F can also be reduced.

The toilet device 1 is provided with an equipment storage section 11 that stores the entire toilet device 41 (at least a part of the toilet device 41) when the toilet device 41 is moved to the storage position. Because the drainage pipe side connection section 65 is disposed within the equipment storage section 11, the entire drainage pipe side connection section 65 and a part of the drainage pipe 61 can be hidden using the equipment storage section 11. Because the ventilation pipe side connection section 67 is also disposed within the equipment storage section 11, the entire ventilation pipe side connection section 67 and a part of the ventilation pipe 62 can be hidden using the equipment storage section 11.

When the toilet device 41 moves between the storage position and the use position, the entire drain hose 66 and the entire ventilation hose 68 are stored inside the equipment storage section 11, so the exhaust hose and the ventilation hose 68 can always be hidden inside the equipment storage section 11.

As shown in FIG. 8, a plurality of drainage pipe side connectors 65 are provided at a plurality of positions on one drainage pipe 61, and a plurality of drainage hoses 66 are individually connected between a plurality of toilet devices 41 provided in a plurality of hospital rooms or rooms and the plurality of drainage pipe side connectors 65. A plurality of ventilation pipe side connectors 67 are provided at a plurality of positions on one ventilation pipe 62, and a plurality of ventilation hoses 68 are individually connected between a plurality of toilet devices 41 provided in a plurality of hospital rooms or rooms and the plurality of ventilation pipe side connectors 67. Therefore, the toilet device 1 of this embodiment can share a single drainage pipe 61 in a facility where toilet devices 41 are provided in a plurality of hospital rooms or rooms.
