JPS6025196B2 - Drainage device for floating objects, etc. - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drainage device that can efficiently drain floating matter floating near the water surface, such as human body grime in a bath, without discharging unnecessary water.

Generally, floating objects floating near the water surface, such as floating objects floating on the water surface of a bath, are pumped out using a bathtub, but at this time, a large amount of unnecessary water is pumped out. could not be properly discharged.

Moreover, it was very time-consuming. Furthermore, since a large amount of water that is not needed is thrown away, there is also a problem in terms of saving resources. Particularly, since such floating substances are discharged from various places such as sinks and washstands, the loss of water resources is large, and this is becoming a problem that cannot be ignored from the perspective of resource depletion. Therefore, it was desired to solve this problem as soon as possible. The present invention meets these demands, and an embodiment of the present invention will be explained below by applying it to a bath.

In the figure, reference numeral 1 denotes a bathtub, and an outer diamond plate 4 called an apron is attached to the outer periphery of the bath wall 2 at a gap 3. 5 is a water level detection box installed in this gap 3,
A gate 6 provided on one side is connected to a gate 7 provided on the tower wall 2 of the bathtub 1.

The above-mentioned entrances 6 and 7 are formed between the maximum water level and the minimum water level stored in the bathtub 1. Reference numeral 8 denotes a flexible overflow pipe made of polyethylene resin, rubber, or the like, and one end of which overflow port 9 is connected to the inside of the water level detection box 5.

This overflow port 9 has floats 10, 10 on both sides thereof.
' is attached so that it can move up and down according to the water level A in the bathtub 1. Furthermore, this overflow port 9 is provided with a float 10 so that its lower end is located slightly below the water level A.
, 10'. 11 is a drainage box attached to the lower end of the water level detection box 5, and the overflow pipe 8
The drain pipe 12 is connected to the drain channel 13 from the bathtub 1. Reference numeral 14 denotes an on-off valve provided in the drain box 11, which is always biased in the direction of closing by a spring 15, and is opened by pulling up an operating lever 17 connected via a wire 16. .

As shown in FIG. 1, the operating lever 17 is provided on the outside of the bathtub 1 so that it can be easily operated, and is supported by a support plate 18. 19 is the above operating lever 1
This is a box part recessed in the exterior plate 4 of the bathtub 1 in order to position the bathtub 7.

In this overflow device, when the operating lever 17 is pulled up to open the on-off valve 14, the floating objects floating in the bathtub 1 are transported together with water from the overflow port 9 via the Sekiguchi 6 and 7 to the overflow pipe. 8 and is directly drained through a drainage box 11 and a drainage pipe 12.

At this time, since the overflow port 9 is located only slightly below the water level A of the water in the bathtub 1, the amount of water that flows in together with floating objects is very small.

This overflow port 9 is held by floats 10 and 10' and moves up and down as the water level A moves up and down, so even if the water level A rises or falls, it is always located slightly below the water level A. This prevents the water level A from falling and floating matter not being able to be discharged, and conversely from rising and causing excess water to be discharged. In other words, no matter where the water level A is, floating matter can always be disposed of by discharging the minimum amount of water.
Although not explained in the above embodiment, if the water level detection box 5, drain box 11, operating lever 17, etc. are attached to a single chassis to form a unit, the attachment method can be changed depending on the shape and material of the bathtub. By considering only the above, it is possible to incorporate it into the bathtub just by drilling holes.

In other words, even a bathtub that has already been installed can be easily installed with simple processing. In addition, it can be installed in water tanks other than bathtubs, such as sinks and washstands, and its range of applications is extremely wide. As described above, according to the present invention, floating matter floating near the water surface can be efficiently discharged, and the discharge can be carried out efficiently regardless of increases or decreases in the water level, resulting in large and medium savings in water resources. It has great industrial value, such as the fact that it becomes possible.
