  The present invention relates to a toilet apparatus that can be installed in a place other than the toilet space, and more specifically, for example, a flush toilet apparatus used by an elderly person or a sick person who needs to be used in a place other than the toilet space, And its drainage system.

  Conventionally, a toilet device is installed in a toilet space that has been designed and constructed in advance, and an appropriate drainage pipe slope, caliber, etc. are determined depending on the location of the toilet space, and sewage containing filth and urine (manure) is collected. It was configured to discharge into the sewage system. On the other hand, a toilet apparatus that can be installed in a place other than the toilet space has been proposed in order to cope with elderly people, sick people, and the like who have to use in places other than the toilet space.

  In such a toilet device, sewage is temporarily stored in a sewage storage tank, and the sewage is allowed to flow after being stirred. Therefore, in order to keep the internal pressure of the sewage storage tank almost constant at all times, a pressure adjustment bag communicating with the inside of the sewage storage tank is provided as an internal pressure adjusting device (see Patent Document 1 below).

JP 2005-155256 A

  However, according to the study of the present inventor, even if a pressure adjusting bag as in the above prior art is provided, the pressure adjusting bag may not be inflated smoothly if the use of the toilet device is continued. I found it. The pressure adjustment bag should be inflated smoothly when pouring sewage into the sewage storage tank to adjust the internal pressure of the sewage storage tank, but if it does not swell smoothly when necessary, the inflow of sewage from the toilet body will be hindered. Therefore, there is a risk that the role that the toilet device should play cannot be fulfilled.

  The present invention has been made in view of such problems, and the object of the present invention is a toilet device including a bag-shaped air storage unit communicated with the inside of a sewage storage tank, and is a case where the use is continued.

Condensed water, which is the cause of this, can be reliably discharged, and the cause of the close contact of the inner wall of the air storage portion can be directly reduced.

  In the toilet apparatus according to the present invention, it is also preferable that the drainage guiding means has a slope formed on the bottom surface of the air storage part toward the air discharge part.

  In this preferable aspect, the dew condensation water in the air storage unit can be reliably reduced with a simple configuration in which a gradient toward the air discharge unit is provided on the bottom surface of the air storage unit.

  In the toilet apparatus according to the present invention, it is also preferable that the gradient is larger on the peripheral side than on the center side of the bottom surface of the air storage unit.

  In this preferable aspect, by increasing the gradient toward the peripheral side rather than the central side of the bottom surface of the air storage part, the dew condensation water on the peripheral side can be reliably collected on the central side, and the air storage part is more easily adhered. The dew condensation water in the outer peripheral portion of the can be reliably drained.

  Further, in the toilet apparatus according to the present invention, the drainage guiding unit is configured such that a gradient is formed on the bottom surface of the air storage unit toward the air discharge unit when the air storage unit is deflated. It is also preferable to provide a support member that supports

  In this preferred embodiment, since the support member is provided so that a gradient is formed on the bottom surface of the air storage portion, only the flexible sheet-like material can be used for the air storage portion. Can be secured. Furthermore, since the support member supports the air storage portion, it can be supported in a suitable manner so that a desired gradient is formed over a long period of time.

  Moreover, in the toilet apparatus which concerns on this invention, it is also preferable that the said supporting member is a support tray which supports the bottom face of the said air accommodating part.

  According to this preferable aspect, since a gradient is formed in the air storage portion by the support tray, even if the air storage portion is formed of a more flexible sheet-like material, the air storage portion can be surely provided with a desired gradient. Can be formed.

  Moreover, in the toilet apparatus which concerns on this invention, it is also preferable that the said air exhaust part is provided in the center of the bottom face of the said air accommodating part.

  In this preferable aspect, it becomes easy to keep the distance from the outer periphery that defines the bottom surface of the air storage portion constant, and it is possible to suppress water from being accumulated in a part of the bottom surface.

You may comprise so that it may flow. Thus, as the water supply unit 2, any means for supplying cleaning water to the toilet body 1 can be adopted.

  Moreover, the drainage flow path 12 is extended outside, for example from the back surface of the toilet bowl main body 1, and is connected to the sewage storage part 3 which has the tank-shaped space for storing the sewage W, for example. The connection end of the drainage channel 12 is open to the internal space of the sewage reservoir 3, and a flap valve, for example, for opening and closing the opening may be provided. Further, the sewage storage unit 3 is provided with a ventilation valve 31 and an airbag 32. The vent valve 31 is a valve that is opened only when the sewage W is discharged and can take air into the internal space of the sewage storage unit 3 and the drainage passage communicating therewith, and is closed immediately thereafter. There is no particular limitation. Moreover, the airbag 32 is for adjusting the pressure in the internal space of the sewage storage part 3, and the waste_water | drain path | route connected to it.

  Furthermore, in this embodiment, a pulsator 41 (stirring means) and a pump 43 (pressure feeding means) are provided inside the sewage reservoir 3. The pulsator 41 pulverizes the filth in the sewage W stored in the sewage storage unit 3 by rotating operation, and the pump 43 functions to pump the sewage W containing the crushed filth to the drain pipe 42.
