Abstract

PURPOSE:To save water and heating energy by circulating tap water containing floatings on the surface and removing said floatings by filter. CONSTITUTION:By operating a circulation pump 20 and circulating bathtub water 7, said bathtub water 7 passing through an upper circulation pipe 3 spouts out into a large diameter tube 3a out of a spouting nozzle 21. At that time, water in a circulation line 15 is circulated by ejection action generated around the spouting nozzle 21, and water spouts out into a bathtub 9 from a spouting outlet 22. When water in the circulation line 15 is circulated, a suction port 19a of a tube 19 floats up on the water surface, and floatings 4 are sucked in from a suction port 19a together with tap water, passes through a fixed tube 18 and a filter 16 and are removed by the filter 16, while bathtub water 7 from which floatings 4 are removed passes through the circulation line 15, a large diameter tube 3a and a spouting outlet 22 and comes into the bathtub 9. Said circulation is repeated, and floatings 4 are removed by the filter 16.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the structure of a purification system for removing scales and the like floating on the surface of bathtub water.

PRIOR TECHNOLOGY In general, floating objects such as scale, dirt, hair, etc. floating in the bath water give a feeling of unsanitaryness to those who are about to take a bath, and this makes them very dissatisfied. In addition, it is very troublesome to scoop and remove floating objects floating in the bathtub water using a container or the like. Therefore, conventionally, as shown in Fig. 2, the bathtub 9
A water inlet 5 whose height can be adjusted in the vertical direction is provided, and a connected vibro connected to this and a drain valve 1o are installed, and at the same time the drain valve 10 is opened, the water solenoid valve 12 is opened, and the water heater 14 is opened. The heated hot water is passed through the hopper 13 and into the bathtub 9 via the bath heat exchanger 1 for reheating, the upper circulation pipe 3, and the lower circulation pipe 2, and the suspended solids 4 are poured into the bathtub 9 through the water intake port 5. water 7
together with overflow, connected vibro, drain valve 1
0 was completely passed through and discharged from the drain port 11. In the figure, 8
is a heating machine.

Problems to be Solved by the Invention In the conventional example shown in Fig. 2, all of the bath water containing floating objects 4 is discharged outdoors, so it is necessary to replenish the missing hot water, which is not economical. The losses were very large. Therefore, the present invention solves the above-mentioned drawbacks of the conventional example, and aims to save water and heating energy by circulating clean water containing floating matter on the water surface and removing it with a filter.

Means for Solving the Problems The present invention provides a bathtub water circulation path with an outlet communicating with the bathtub, a filter detachably inserted from the bathtub at the entrance side of this VI loop path, and a water circulation path through which the water is circulated through the bathtub. a floating pipe communicating with the entrance of the selling ring road and having a water intake at the top;
A circulation pump is provided which circulates the bathtub water through the circulation path by an ejecting action generated by discharging the bathwater from the outlet of the circulation path.

Operation When the circulation pump is operated to circulate water using the above means, the pipe body floats up so that its water inlet is located below the water surface, and the floating matter floating on the water surface together with the clean water is removed from the pipe body and the filter. The water, which is filtered out and free of floating matter, passes through the circulation path and enters the water in the bathtub from the outlet.

Example? X! Figure J1 shows a purification system according to an embodiment of the present invention, in which the same parts as in the above-mentioned conventional technology are given the same reference numerals, detailed explanations are omitted, and different parts will be mainly explained. Reference numeral 15 indicates a circulation path consisting of a pipe that passes through the lower circulation pipe 2 and has an inlet 15a facing the bathtub 9 side and an outlet 15b connected to the bathtub 9 via the upper circulation pipe 3;
This filter is supported by a holder 17 and is detachably attached to the entrance 15a of the circulation path 15 from inside the bathtub 9. 18 is connected to the holder 17 and the filter 1
6 is an upright fixed pipe that communicates with the inlet 15a; 19 is a pipe body that is connected to the fixed pipe 18 in a vertically movable manner and whose upper water intake port 19a can be moved below the water surface by buoyancy;
0 is connected to the outlet side of the bath heat exchanger 1 on the suction side, and connected to the upper circulation pipe 3 on the discharge side. Upper circulation pipe 3
The connection side with the bathtub 9 is a large-diameter pipe 3a, and therein is a spout nozzle 21fz that communicates with the thin upper circulation pipe 3! :, large diameter pipe 3
It is located ahead of the circulation path 15 facing A. A gap is provided at the tip of this jet nozzle 21 and the jet port 22 is connected to the exit 15.
b.

In the above embodiment, when the pump 20 is operated to circulate the bath water, the bath water that has passed through the upper circulation pipe 3f is vigorously discharged from the spout nozzle 21 into the acupuncture point pipe 3a, and at this time, In is generated around the spout nozzle 21. The water in the circulation path 15 is circulated by the ejecting action, and the water is also circulated at the spout 22.
Water gushes out into the bathtub 9. Therefore, when the water in the circulation path 15 is circulated, the water intake port 19a of the pipe body 19 rises to the water surface, and the floating matter 4 is removed from the water intake port 19a along with the clean water.
.

The suspended matter 4 is removed by the filter 16, and the water 7f'i from which the suspended matter has been removed passes through the circulation path 15 and the large-diameter pipe 3a spout 22. Enter bathtub 9. The above circulation is repeated and the floating matter 4 is removed by the filter 16. Note that the lower circulation pipe 2 and the holder 17 are connected to the suction port of the pump 20.
, the bathtub water 7 is sucked in through the gap formed between the circulation path 15 and through the lower circulation pipe 2 and the bath heat exchanger 2S1.

Effects of the Invention Floating objects such as scale, dirt, hair, etc. can be reliably removed, and since the filter can be easily attached and removed from the bathtub, the filter can be easily cleaned. Furthermore, during purification, there is no need to dispose of the hot water in the bathtub outside as in the conventional method, so it is very economical, not only water saving but also fuel cost savings due to not refilling hot water.
