Abstract

PROBLEM TO BE SOLVED: To provide a portable toilet to lessen the quantity of washing water for a toilet bowl. SOLUTION: Water inside a tank 12 is able to be supplied into a spray nozzle 14 through a piping such as a tube 16, a pump 17, a three way changeover valve 18 and a piping 19. The water inside the tank 12 becomes warm water during going through a piping 20 branched off from the three way changeover valve 18 and a heater 21, and is able to be supplied into a washing nozzle of warm water 15. After being used by sitting on a toilet seat 22, the buttocks is washed by the washing nozzle of warm water 15 and is dried with a warm air stream fan. From a spray nozzle 14, water is sprayed and it washes the toilet bowl part 5. Since water is sprayed from the spray nozzle 14 to wash the toilet bowl part 5, the quantity of washing water is lessened and the number of times to wash a bucket 9 and to pour water into the tank 12 can be saved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable toilet, and more particularly to a portable toilet provided with toilet bowl washing means.

[0002]

2. Description of the Related Art In order to enable persons with physical disabilities to use their toilets in rooms other than toilet rooms such as bedrooms, there are increasing examples of providing portable portable toilets in bedrooms and the like. I have.

A portable toilet having a flush toilet is described in Japanese Patent Application Laid-Open No. Hei 8-71015.

[0004]

The problem to be solved by the invention is disclosed in Japanese Patent Application Laid-Open No. 8-710.
In the toilet of the No. 15 portable toilet, a rim similar to a normal Western style toilet bowl is provided, and the toilet bowl washing water is supplied to the rim to wash the inner surface of the toilet bowl.
Large amount of toilet bowl washing water.

An object of the present invention is to provide a portable toilet capable of uniformly flushing the inner surface of a toilet bowl with a small amount of toilet water.

[0006]

A portable toilet according to the present invention comprises a movable base, a toilet bowl mounted on the movable base, a bucket arranged below the toilet bowl, and a toilet bowl. In a portable toilet having a toilet seat arranged on the upper side of the toilet and a means for supplying pot flushing water to the toilet bowl, the pot flushing water supply means is disposed at a rear portion of the toilet bowl and faces toward the inner surface of the toilet bowl. A spray nozzle for spraying water is provided.

[0007] In such a portable toilet, since water is sprayed from the spray nozzle to the inner surface of the toilet bowl, even a small amount of water can be poured all over the inner surface of the toilet bowl and washed uniformly. .

In the present invention, a spray nozzle may be used which comprises a cylinder and a nozzle body fitted in the cylinder and capable of protruding forward from the tip of the cylinder.

By flushing the toilet bowl by projecting it from the nozzle body and the tip of the cylinder, it is possible to sufficiently pour water on the front side of the toilet bowl. In addition, by retracting the nozzle body, it is possible to prevent the nozzle body from being stained during use or the like.

In the present invention, a driving device for moving the spray nozzle forward and backward may be provided. By spraying water from the spray nozzle while moving the spray nozzle forward and backward, water can be poured evenly over the entire toilet bowl.

In the present invention, a hot water washing nozzle for jetting hot water toward the buttocks of a human body sitting on a toilet seat is juxtaposed with the spray nozzle, and the spray nozzle and the hot water washing nozzle are connected to a common valve device. Is preferred. With this configuration, most of the water passage mechanism to the hot water washing nozzle and the water passage mechanism to the spray nozzle can be shared, thereby simplifying the equipment and reducing the cost.

Incidentally, the hot water washing apparatus is conventionally provided with a forward / backward drive device for adjusting the front / rear position of the hot water washing nozzle. In the present invention, the spray nozzle may be moved forward and backward by using the forward and backward drive device. For this purpose, the spray nozzle and the hot water washing nozzle may be supported by a common member, and both nozzles may be integrally movable forward and backward.

In the present invention, a tip having a jet of cleaning water may be detachably provided at the tip of the spray nozzle. By doing so, the tip portion can be removed and cleaned. Further, the manufacture of the spray nozzle is also facilitated.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a longitudinal sectional view of a portable toilet according to an embodiment, FIG. 2 is a perspective view of the portable toilet, FIG. 3 is a perspective view of a spray nozzle and a hot water washing nozzle, and FIG. 4 is a spray nozzle and a hot water washing. FIG. 3 is a diagram of a water flow system to a nozzle.

The movable base 1 has a caster 2 at a rear part, and can be moved in a transmission direction by lifting a front part. The reason why the casters are not provided at the front portion of the movable base 1 is to stop the movable base at a fixed position by bringing the front portion into direct contact with the floor 3.

A rim portion 4 is provided at the front of the upper surface of the movable base 1.
Is provided, and a pot portion 5 is provided below the rim portion 4. The rim portion 4 and the pot portion 5 constitute a toilet bowl 6. A lid 8 is attached to the outlet 7 of the bowl 5.
When using this portable toilet, remove the lid 8,
After use and washing, the lid 8 is attached again.

A bucket 9 for receiving waste is disposed below the outlet 7 of the bowl 5. The rear surface of the movable base 1 is a door 10 that can be opened and closed. The door 10 can be opened to put the bucket 9 in and out.

If the toilet bowl 6 and the bucket 9 are integrally formed of resin, it is convenient to replace them when they become dirty at once.

A tank cover 1 is provided on the rear upper surface of the movable base 1.
1 is provided, and a tank 12 for storing washing water is provided in the tank cover 11. The upper part of the tank cover 11 is provided with a detachable cover top 13.

From the bottom plate 144, the arms 146
Are extended, and the end of the arm 146 is
It is fixed to. That is, the bottom plate 144 is
Are supported by the support 128.

The upper surface of the bottom plate 144 is a horizontal flat surface, and the rear end of the bottom plate 144 has a pot 15 with a pot.
A bent portion is provided so that 4 does not move rearward from the set position in a state of use.

The pot with pot 154 is provided with the upper toilet bowl 150.
And a waste storage tank 152 as a lower bucket. The toilet bowl 150 is provided with a rim 148 along the upper end and the periphery.

The rim portion 148 has a separate structure from the main body of the toilet bowl 150.

The main body portion 160 of the waste storage tank 152 has a substantially cylindrical shape. Therefore, there is no problem that dirt remains inside the corner and it is difficult to clean, and the dirt collects in the substantially central portion of the bottom in the dirt storage tank 152.
Discharge at the time of the discharge operation is also facilitated.

The waste storage tank 152 has a discharge cylinder portion 162 which has a cylindrical shape and is inclined upward, and a discharge port 164 for discharging waste in the waste storage tank 152 at the tip.
Are formed. Then, the waste inside the waste storage tank 152 can be easily discharged to the outside through the discharge cylinder portion 162 and the discharge port 164.
