BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body washer for cleaning a body by contact with a rotatingly driven cleaner.

[0002]

2. Description of the Related Art It is common practice to wash parts of a body by applying a detergent to a washing body such as a towel or a sponge, whipping the detergent, and then rubbing the body. There are many. In particular, the elderly and handicapped have difficulty cleaning their backs and require nursing care.

In order to eliminate such inconvenience, a cleaning tool such as a sponge containing a cleaning liquid is rotated, the cleaning tool is moved in the vertical direction, and the body is cleaned by contact with the cleaning tool. Automatic cleaning devices have been proposed.

[0004]

The conventional automatic cleaning apparatus is of a fixed type which is installed in a bathroom, so that it is difficult to dry it when it is exposed to water or hot water. Screws and parts are susceptible to corrosion by oxidation, and there is a problem in durability. Further, when cleaning the bathroom, the cleaning device often hinders the bathroom.

[0005] In view of the above, the above-mentioned problem can be solved by using an installation type which is placed on the floor in the bathroom, so that it can be taken out of the bathroom. The stability of the guide member for guiding the ascending and descending movement is poor, and if the body weight is given to the cleaning tool, the guide member is tilted or falls down and cannot be used, and there is no known body-mounted body cleaning device.

An object of the present invention is to provide a floor-installed body washing device capable of obtaining a stable use state.

[0007]

In order to solve the above-mentioned problems, according to the present invention, a lower end of a guide member is supported by a base mounted on a floor of a bathroom, and the guide member is moved along the guide member. A motor is incorporated inside a motor case supported to be able to move up and down, and an elevating mechanism for moving the motor case up and down along a guide member using the motor as a driving source is provided, and a motor case of a drive shaft rotatably driven by the motor is provided. Connect the cleaning tool to the tip that penetrates and faces the outside,
The configuration is such that a load supporting portion is provided which is pressed onto the floor surface by the load applied to the gantry. Here, the applied load refers to the weight of the user who uses the body washing device.

As described above, if the load support is provided on the gantry, the bath chair is placed on the load support and the load support is pressed down on the floor by sitting on the chair. It is possible to stabilize, and even if a load is applied by pressing a part of the body, for example, the back to the cleaning tool that is moved up and down while rotating, the guide member is inclined, or there is no inconvenience such as falling down, A stable use state can be obtained.

In addition, since it is a floor-mounted type, it can be taken out of the bathroom. For this reason, there is no hindrance to the cleaning of the bathroom, and the body washing device can be naturally dried outdoors, thereby preventing oxidative corrosion of each part and suppressing a reduction in the life.

Here, as a lifting mechanism for raising and lowering the motor case, a rack and pinion mechanism for mounting a vertically long rack on a guide member and a pinion meshed with the rack on a drive shaft is employed to clean the body. The device can be reduced in size and weight, and can be easily carried.

When a motor with a speed reducer is adopted as the motor and a drive shaft is directly connected to the output shaft of the speed reducer,
Compared to a case where a speed reduction mechanism is incorporated between the motor and the drive shaft, the number of parts is reduced, the size and weight of the motor case are reduced, and a lightweight and easy-to-handle body washing device can be obtained.

In the body washing apparatus according to the present invention, when the gantry is formed by three legs, the body washing apparatus can be installed at a corner in the bathroom, and the corner can be used effectively.
