Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bathtub that is convenient for manually bathing bedridden elderly people or sick people who have difficulty getting up and moving.

[Conventional technology]

In order to reduce manual labor when using this type of bathtub, a washstand is installed inside the bathtub, and by placing the bather on the washstand and lowering the washstand, the bather can enter the hot water inside the bathtub. The technique of lifting the washstand out of the hot water for washing was previously proposed by the applicant of the present invention in Japanese Patent Application No. 58-205200, and also disclosed in Japanese Utility Model Application No. 58-98916.

[Problem that the invention attempts to solve]

However, the above-mentioned conventional bathtub has a drawback in that it is difficult to dispose of the dirty hot water that is generated during the cleaning operation performed in the washing basin, and the hot water in the bathtub is contaminated.

[Means of trying to solve the problem]

This invention prevents the contamination of the hot water in the bathtub due to the above-mentioned conventional cleaning and maintains the hot water in the bathtub clean from beginning to end. to form a drainage gutter,
A hot water drain hose connected to the hot water drain gutter was fitted into and removed from a hot water drain port provided in the bathtub, and dirty hot water generated by washing on the wash basin was stored in the hot water drain gutter around the periphery of the wash basin. After that, the hot water was discharged from the hot water hose to the outside of the bathtub through a hot water outlet provided in the bathtub, thereby eliminating the possibility of the hot water in the bathtub becoming dirty.

〔Example〕

In the drawing, 1 is a bathtub, and a washing table 2 is accommodated in the bathtub so that it can be moved up and down.

In the illustrated example, the washing table 2 moves up and down as follows.

That is, approximately U-shaped undulating members 3, 3 are provided at the inner bottom of the bathtub 1.
A pair of left and right sides are provided so that one side 3a is pivotally supported on the bottom of the tank and the other side can be raised and lowered on the lower surface of the washing table 2, and an arm plate 3 is provided on one side of each undulation member 3 to protrude upward.
b was provided, one end of which was tied to the upper end of the wire 4, and the other end of the wire 4 was tied to the winding drum of a winding machine 5 installed at the upper edge of one side of the bathtub 1. Further, the winding machine 5 in the illustrated example is formed by rotating a worm wheel 5c by a worm 5b driven by a manual handle 5a, and a winding drum 5d provided coaxially with the wheel axis, so that a worm wheel 5c is provided coaxially with the worm wheel 5c. Therefore, the winding drum 5d is rotated to wind up and unwind the wire 4, and in conjunction with this, the left and right undulating members 3, 3 are simultaneously undulated, and the washing table 2 is moved upward by its activation. If the undulating member 3 falls down, the washing stand 2 will be lifted out of the bathtub 1 by its own weight.
I made it sink inwards. The hoist 5 may be a ratchet type drive means equipped with a stopper, and the means for vertically moving the washing table 2 is not limited to the push-up type shown in the figure, but may be a lifting type or other type. Appropriate equipment may be employed.

A drain gutter 6 lower than the table surface is formed at the periphery of the washing table 2. The drain gutter 6 is sloped gradually deeper from the head side to the foot side of the bather who is lying on the table 2 to improve the flow of the drain water, and a flexible material such as rubber or vinyl is attached to the lower side of the slope. A hot water drainage platform 7 is provided in communication with the vicinity of the bottom of the gutter. A hot water drain port 8 is provided on the side of the bathtub 1 on the side where the hot water drainage platform 7 is provided at a position above the hot water level in the bathtub 1, and as will be described later, when the washing table 2 is moved upward to wash a bather. A hot water drain hose 7 communicating with the hot water drain gutter 6 is fitted into the hot water drain port 8, so that the hose 7 can be pulled out from the hot water drain port 8 when the washing table 2 is moved down into the bathtub 1 after washing. .

A pedestal 9 on which the head of a supine bather is placed is provided on the upper surface of one side of the washing table 2.

In the figure, 10 indicates a hot water outlet in the bathtub 1.

[Effect]

In the above configuration, the washing stand 2 is moved upward by the drive of the hoisting machine 5 to make the bather lie down on its upper surface, and then the washing stand 2 is moved down and the bather is placed in the hot water in the bathtub 1 to suit his/her needs. After bathing, the washing table 2 is moved up again to perform washing.In this case, the lower edge is pushed into the drain gutter 6 and the upper edge of the bathtub 1 is moved as shown by the dotted line in FIG. By enclosing the washing basin 2 in the upward movement position with the enclosing sheet 11 held by a temporarily installed support 12 and washing, the washing work can be easily carried out without dirty hot water scattering around or falling into the bathtub 1. When the stand 2 is moved up, if the hot water drainage platform 7 is fitted into the hot water outlet 8 of the bathtub 1, the stand 2 can be removed.
Dirty soapy water, etc. flowing down the top is drained from the peripheral drainage gutter 6.
The hot water flows into the bathtub, flows to one side according to the slope, and is discharged from the hot water hose 7 to the outside of the bathtub via the hot water outlet 8, so that the hot water inside the bathtub is not contaminated. After the washing is finished, the washing table 2 is moved down again to give the bather a warm bath with hot water in the bathtub, and the bathing table 2 is then moved up to transfer the bather to a bed or the like to finish the bathing.

[Effect of idea]

In this way, according to the present invention, a hot water drain gutter is provided around the periphery of the washstand that is moved up and down in the bathtub, and a hot water drain platform that communicates with the hot water drain gutter is provided in the bathtub during cleaning operations when the washstand is moved up and down in the bathtub. Because it is installed in such a way that it can be fitted and removed from the hot water outlet, the dirty hot water from cleaning is collected in the drain gutter and does not mix into the bathtub, and moreover, it can be removed from the hot water outlet via the hot water outlet platform. The bathtub can be discharged outside the bathtub, thus facilitating cleaning work during bathing and reliably preventing the hot water in the bathtub from being contaminated.
