Description

TECHNICAL FIELD The present invention relates to the structure of a purification system for removing scales and the like floating on the surface of bath water.

Conventional technology Generally, floating materials such as scales, dust, and hair floating in the bathtub water make people feel unhygienic when trying to take a bath.
I was very dissatisfied with this. Moreover, it was very troublesome to scoop up and remove floating matters floating in the bath water with a container or the like. Therefore, conventionally, as shown in FIG. 2, a bath water 9 is provided with a vertically adjustable height water intake 5, and a connecting pipe 6 and a drain valve 10 leading to this are provided.
At the same time when 10 is opened, the water solenoid valve 12 is opened, the hot water heated by the water heater 14 is passed through the hopper 13, and the bath heat exchanger 1, the upper circulation pipe 3, and the lower circulation pipe 2 for reheating are used to pass the bath. It was put in the container 9, and the suspended matter 4 was overflowed together with the clean water 7 from the clean water inlet 5, and was discharged from the drain 11 through the connecting pipe 6 and the drain valve 10. In the figure, 8 is a heater.

Problems to be Solved by the Invention In the conventional example shown in FIG. 2, all the clean water in the bathtub water containing the suspended matter 4 is discharged to the outside, so it is necessary to replenish the shortage of hot water, which is economical. The loss was very large. Therefore, the present invention solves the above-mentioned drawbacks of the prior art, and circulates clean water containing suspended matter on the water surface and removes it with a filter to save water and save heating energy.

MEANS FOR SOLVING THE PROBLEMS The present invention is directed to a bathtub water circulation path having an outlet communicating with a bathtub, a filter detachably attached to the entrance side of the circulation path from the bathtub, and the circulation path of the circulation path via the filter. A floatable pipe body communicating with the inlet and having a water suction port at the upper portion, and a circulation pump for circulating the bath water in the circulation passage by an ejecting action generated by discharging the bath water from the outlet of the circulation passage Is.

When the circulation pump is operated and water is circulated by the above means, the pipe floats up so that its water intake is located below the water surface, and floating substances floating on the water surface along with clean water cause the pipe body and filter to The water, which has been removed by a filter and except for suspended solids, enters the water in the bathtub from the outlet through the circulation path.

Embodiment FIG. 1 shows a purification system according to an embodiment of the present invention. The same parts as those of the above-mentioned conventional technology are designated by the same reference numerals, detailed description thereof will be omitted, and different parts will be mainly described. Reference numeral 15 is a circulation path consisting of a pipe which penetrates the lower circulation pipe 2 with its inlet 15a directed toward the bath 9 and its outlet 15b is connected to the bath 9 via the upper circulation pipe 3, and 16 is a filter for removing the suspended matter 4. It is supported by the holder 17 and is detachably attached to the inlet 15a of the circulation path 15 from the inside of the bath 9. 18 is an upright fixed pipe that is connected to the holder 17 and communicates with the inlet 15a through the filter 16, and 19 is vertically movably connected to the fixed pipe 18, and the upper water suction port 19a moves below the water surface by buoyancy. The tube body that can be formed, and the pump 20 is connected to the suction port side at the outlet side of the bath heat exchanger 1, and the discharge port side is connected to the upper circulation pipe 3. The upper circulation pipe 3 has a large-diameter pipe 3a on the side connected to the bath 9, and a jet nozzle 21 communicating with the thin upper-circulation pipe 3 is provided in the large-diameter pipe 3a.
It is provided prior to the circulation path 15 facing the. The ejection port 22 faces the outlet 15b with a gap provided at the tip of the ejection nozzle 21.

In the above embodiment, when the pump 20 is operated to circulate the bath water, the bath water passing through the upper circulation pipe 3 is ejected from the nozzle 21.
Therefore, the water in the circulation path 15 is circulated through the jet pipe 21a by the ejecting action generated around the jet nozzle 21 at this time, and the water is jetted from the jet outlet 22 into the bathtub 9 together. Then, when the water in the circulation path 15 is circulated, the water inlet 19a of the pipe body 19 floats up to the surface of the water, and the suspended matter 4 is sucked together with clean water from the water inlet 19a, passes through the fixed pipe 18, the filter 16, and the filter. At 16, the suspended solids 4 are removed, and the bath water 7 from which the suspended solids have been removed enters the bathtub 9 through the circulation path 15 and the spout 22 of the large pipe 3a. By repeating the above circulation, the suspended matter 4 is removed by the filter 16. In addition,
The suction port of the pump 20 has a lower circulation pipe 2, a holder 17, and a circulation path.
The bath water 7 is sucked through the gap formed between 15 and through the lower circulation pipe 2 and the bath heat exchanger 1.

EFFECTS OF THE INVENTION According to the present invention as described above, since the suspended matter floating on the bath water is removed by the filter, the scale is surely
Floating matters such as dust and hair can be removed, and the filter can be easily attached to and detached from the bathtub, so that the filter can be easily cleaned. In addition, since it is not necessary to dispose hot water or water in the bathtub outdoors during purification, it is very economical not only to save water but also to save fuel cost by not supplying hot water.

In particular, the tube body floating above the water surface promotes the circulation of new bath water between the hot water of the water surface and the outlet of the circulation path, so that the boiling temperature can be made uniform depending on the water level of the bath.
