Abstract

PURPOSE:To drain the water mixed with a detergent or the like through a conventional drain pipe and feed the water to be reused to a washing tub through a dedicated pipe system by providing a drain hole for reuse in addition to a conventional drain hole on the bottom face of a bathtub. CONSTITUTION:A drain hole 2 for waste water and a drain hole 3 for the water to be reused are provided on the bottom face of a bathtub 1, and plugs 2', 3' are inserted into them respectively. The drain hole 2 for waste water is connected to a pipe 4. When the bathtub 1 is washed with a detergent or the like, the plug 2' is opened, and the waste water is discarded through the pipe 4. When the plug 3' of the drain hole 3 is opened, the water to be reused after bathing can be utilized for flowers and trees or sprinkling via a valve 6 through a pipe 5. When the water can not be drained by the gravitational force alone, a pump is connected next to the valve 6, and the necessary discharge pressure is obtained. When a system of the drain hole 3 and the pipe 5 is separately provided as a means to reuse the water after bathing, the water containing no detergent can be separated and simply utilized, and this system is convenient for reusing the water of the bathtub 1 with a simple structure.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a bathtub used in general households and the like.

[0001] [Prior Art] In a conventional bathtub, there is only one drain hole on the bottom surface for purposes such as circulation filtration and heating.

[0002] [Problems to be solved by the invention] In the conventional bathtub, there is only one drain hole on the bottom surface, and the drainage after washing the bathtub with a detergent and the drainage after the bath are all discharged from the same drainage hole. Was there. However, when considering water resources, even if the water used to wash the bathtub with detergent is discarded, the water used for bathing can be used for watering plants, washing, etc. You should do it.

[Problems to be Solved by the Invention] In a conventional bathtub, both the water washed with a chemical and the water after the bath had to be drained into the same drain pipe. For this reason, in order to use the water after the bath in which no chemicals are mixed, it is necessary to use a bucket or a pump to sprinkle water or put it in a washing machine or the like.

[Means for Solving the Problems] In addition to the conventional drainage plug for disposal, a drainage plug for reuse is provided on the bottom surface of the bathtub.

[Operation] By providing a drain hole for reuse in the bottom surface of the bathtub in addition to the conventional drain hole, water mixed with a detergent or the like is drained through a conventional drain pipe and reused. In this case, water can be supplied to garden trees, washing tubs, etc. through a dedicated piping system.

[0006] [Effects of the Invention] Water is becoming a valuable resource, and effective use and reuse have been required, but it has been customary to pump water out of a bath and use it. If you throw away 200 liters at a time, 73 tons per year and 1 ton 4
It will be 29,200 yen as 00 yen. If a drainage hole and a piping system are separately provided as means for reusing the water, water containing no cleaning agent can be separated and easily used. The additional piping cost for reuse can be fully recovered with the price of water saving.
That is, the present invention has an extremely simple structure and is convenient for reusing the water in the bathtub.

[Example] [Example] FIG. 1 is an illustration showing a bathtub embodying the present invention in a trigonometric method. A drainage hole 2 for waste water and a drainage hole 3 for reused water are provided on the bottom surface of the bathtub 1, and plugs 2 ', 3'are provided for each.
Fit. The drainage hole for waste water is connected to the pipe 4, and when the bathtub is washed with detergent or the like, the plug 2'is opened and the pipe 4 is discarded. The reused drainage after bathing by a person can be used for other purposes such as watering the flowers and trees by the valve 6 through the pipe 5 by opening the plug 3'of the drainage hole 3. When drainage cannot be performed only by gravity, as shown in FIG.
The required discharge pressure can be obtained by connecting.
