DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body washing apparatus for washing a body of a person to be washed (patient) in a housing room by spraying warm water or water on the body of the person to be washed, and particularly to a body washing apparatus such as a bathroom. The present invention relates to a body washing device installed on a floor surface having a drain port.

[0002]

2. Description of the Related Art As a conventional technique, there is one described in Japanese Patent Application Laid-Open No. Hei 7-308355 filed by the present applicant. That is, the upper, lower, left, right, and rear surfaces are closed by a hard resin material such as Duracon (trade name), and a window hole that exposes the entrance of the person to be cleaned on the front surface and exposes the head of the person to be cleaned on the front side of the upper wall. Is formed, and the left and right side walls are hollow side walls having a predetermined space.

[0003] A rigid water guide pipe bent in an inverted U-shape is fixed upright in the side wall, and branch pipes are protruded toward the inside of the main body at three places above, inside, and below the vertical pipe of the water guide pipe. The nozzles are fixed to the projecting ends of the branch pipes, and these nozzles are exposed in the main body. Further, a door for opening and closing the entrance is provided on the front side of the main body. Then, after the person to be cleaned (patient) placed on a wheelchair is accommodated in the main body from the entrance and the door is closed, a cleaning liquid (warm water) is jetted from each nozzle toward the person to be cleaned, and the person to be cleaned is discharged. There was a body washing device adapted to wash.

[0004]

In the above prior art, the rigidity and strength of the main body are increased because the lower surface of the main body is closed by the bottom plate, but the structure becomes complicated and expensive, and the weight and weight are reduced. The height will increase. In addition, when accommodating a person to be cleaned placed in a wheelchair, a guide for guiding the wheel of the wheelchair is required at the entrance, and this guide hinders the passage of the caregiver. In addition, since a hard water guide pipe and a branch pipe are provided in the side wall and a nozzle is connected to the tip of the branch pipe, piping cannot be performed unless the side wall and the low plate of the main body are assembled and divided, There are drawbacks such as troublesome assembly and maintenance of piping. An object of the present invention is to provide a novel body washing device that has solved the above-mentioned disadvantages.
