Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath water circulation purification device for clarifying and reusing it while circulating bath water, and more particularly to a bath water circulation purification device capable of cleaning a purifying material.

[0002]

2. Description of the Related Art Purifying and repeatedly using bath water stored in a bathtub not only saves a great deal of bath water, but also replaces bath water and cleans the bath due to stains on the bath water. It is also effective in reducing Therefore,
BACKGROUND ART A circulating water purification apparatus for bath water, which circulates the bath water continuously to purify it, has been developed.

FIG. 2 shows an example of a bath water circulation purification apparatus.
This device sucks the bath water using a pump or the like, filters the water, and then circulates the water in the bath to continuously purify the water. In the figure, reference numeral 1 is a bathtub, and 2 is a bath water circulation purification apparatus. The bath water circulation purification device 2 has a configuration in which the main body containers 3 are connected by circulation paths 4 and 5. A filter 6, a purifying material 7, and a heat insulation heater 8 are arranged inside the container, and a pump 9 for forcibly circulating bath water is provided in the circulation path 4.

When the pump 9 is operated, the bath water in the bath 1 is sent into the main body container 3 through the circulation path 4,
First, the filter 6 collects a relatively large suspended solid, and then the purification material 7 collects a fine suspended solid.
Furthermore, the circulation heater 5 is heated to an appropriate temperature by the heat retention heater 9
And is returned to the bathtub 1 again. The bath water is clarified by continuously performing such a process.

[0005]

By the way, porous materials such as zeolite, diatomaceous earth, pumice, etc. are used as the purification material 7. However, these porous materials may be absorbed by suspended matter if used for a long period of time. The holes are clogged and the suction force is reduced. Therefore, in the conventional bath water circulation purifying apparatus, the purifying material 7 is taken out from the main body container 3 and washed to be cleaned.
It is necessary to remove the suspended matter adsorbed on. However, at the time of cleaning, it is necessary to temporarily stop the apparatus and disassemble the main body container 3, and the purification material 7 is in a state of adsorbing a large amount of suspended matter, and since it is a large number of particles, cleaning is troublesome. There is such a problem.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a bath water circulation purification apparatus which can easily wash the purification material without disassembling work. .

[0007]

In order to solve the above problems, the present invention takes the following measures. First, in the middle of the circulation path, a detour path that bypasses the filtering means and the purification means and communicates between the pump and the water outlet is provided, and the detour path is formed at the confluence of the circulation path and the downstream end of the detour path. To open the circulation path, or to close the circulation path on the outlet side to connect the bypass and the circulation path on the upstream side to selectively switch the flow path of the bath water. A route switching means is provided. Further, the drain passage is connected to the circulation passage between the filtering means and the purification means, and the drain passage is closed at the connection portion between the circulation passage and the drain passage, or the circulation passage is opened. Second passage switching means is provided for closing the passage to connect the purifying means and the drain passage to selectively switch the passage of the bath water.

Further, air supply means for sending air to the bath water flowing through the bypass may be provided in the middle of the bypass.

[0009]

According to the bath water circulation purifying apparatus of the present invention having the above-mentioned means, the first flow path switching means is operated to block the detour when normal bath water is clarified. At the same time, the circulation passage is opened, and further, the second passage switching means is operated to close the drain passage and open the circulation passage. As a result, the bath water introduced into the circulation path is clarified by flowing through the filtering means and the purifying means in order without flowing into the bypass and the drain flow path.

When cleaning the purifying means, the first flow path switching means is operated to close the circulation passage on the side of the water outlet and to connect the bypass and the circulation passage on the upstream side. By operating the second flow path switching means, the circulation path is closed and the purifying means and the drain flow path are made to communicate with each other. As a result, the bath water does not pass through the filtering means, flows through the bypass path toward the purifying means, passes through the purifying means in the direction opposite to the normal direction, and is discharged from the drain passage to the outside of the bath. When passing through the filtering means, the flow of the bath water is weakened, but by bypassing the filtering means and flowing through the bypass, the flow of water flows toward the purification means without being weakened. Moreover, the bath water flows through the second bypass and passes through the purifying means in the direction opposite to the normal direction. As a result, the purifying material is exposed to the strong flow of the bath water, the suspended matter is washed away, and the purifying material is discharged from the drain passage.

Further, when cleaning the purifying means, the cleaning effect inside the purifying means can be enhanced by sending air into the bathtub water flowing through the bypass by the air supply means so as to contain innumerable bubbles. it can.

By operating this flow path switching valve 62, the bypass 51 can be closed to open the circulation pipe 17 and the water outlet pipe 90, or the circulation pipe 17 can be closed to connect the bypass 51 and the water outlet pipe 90. Is.

Here, the circulation path 1 forming the distribution path of the bath water
0 consists of the circulation pipes 11, 12, ..., 18. In addition, the bypass 50, the circulation pipe 14, and the bypass 51 constitute a bypass 100 that bypasses the bath water.

Further, the pump 20, the compressor 70,
Open / close valve 72 and flow path switching valves 60, 6
Reference numerals 1 and 62 are all controlled by a control means (not shown), and are set so that the cleaning means 40 is regularly cleaned by, for example, a timer.

The operation of the bath water circulation purification device configured as described above will be described. Normally, when the bath water is clarified, the flow path switching valve 60 is operated to close the bypass 50, the circulation pipes 11 and 12 are communicated with each other, and the flow path switching valve 61 is operated to drain the drain pipe 80. And the circulation pipes 15 and 16 are communicated with each other, and the flow path switching valve 62 is operated to bypass the bypass 5
1 is closed and the circulation pipe 17 and the water discharge pipe 90 are connected. Further, the open / close valve 72 is also closed.

At this time, the bath water introduced into the circulation passage 10 flows through the circulation passage 10 without flowing into the bypasses 50, 51, the drain pipe 80 and the compressor 70.
Then, the filtering means 30 collects relatively large suspended matter such as body hair, earth and sand, and lint. Next, in the purifying unit 40, fine floating substances not collected in the filtering unit 30 are collected to clarify the bath water, and the water in the bath is circulated through the water pipe 90 from the circulation pipe 17 and returned to the bath not shown. .

Here, the bath water passing through the purifying means 40 first flows into the bottom portion of the purifying material container 41 from the circulation pipe 16 and fills the inside of the purifying material container 41 so that the water level increases. And since it flows into the inside of the case 43 from the opening of the upper end of the cylindrical member 44, the bath water can be smoothly circulated and the generation of noise can be prevented.

When cleaning the purifying means 30, the flow passage switching valve 60 is operated to close the circulation pipe 12, the circulation pipe 11 and the bypass 50 are communicated with each other, and the flow passage switching valve 61 is operated. Circulation pipe 1
5, the circulation pipe 16 and the drain pipe 80 are communicated with each other, the flow path switching valve 62 is operated to close the water outlet pipe 90, and the bypass 51 and the circulation pipe 1 are connected.
Communicate with 7. Further, the open / close valve 72 is also opened.

The bath water introduced into the circulation path 10 flows through the bypass 50 without passing through the filtering means 30 toward the purifying means 40. At this time, the compressor 70 is operated,
High-pressure air is sent to the bath water toward the purifying means 40 to contain innumerable bubbles. The bath water containing the air bubbles circulates through the circulation pipe 17 from the bypass 51 and vigorously flows in from the lower part of the case 43 that constitutes the purification means 40.
The suspended matter adhering to the surface of the purification material 42 stored in is washed away. The bath water mixed with the removed suspended matter is
3 overflows from the upper part and flows down to the bottom part of the purification material container 41, and is discharged from the circulation pipe 16 through the drain pipe 80 to the outside of the bath not shown.

When the bath water passes through the filtering means 30, its flow is weakened. However, according to the above bath water circulation purification device, the bath water introduced into the circulation path 10 is bypassed through the filtering means 30. By circulating the bypass 100 constituted by the bypass 50, the circulation pipe 14, and the bypass 51, it is possible to flow toward the purifying unit 40 without weakening the flow force of the bath water.

Further, the bath water having a strong flow force is circulated through the circulation pipe 17 from the bypass 51 and passes through the purifying means 40 in the direction opposite to the normal direction. Here, in the case of normally clarifying the bath water, the bath water passing through the purifying means 40 flows from the upper part of the case 43, so that the suspended matter in the bath water is located near the upper part of the case 43.
2 is attached to a relatively large amount, and individual purification materials 42
Attached to the upper surface of. Therefore, the bath water should be placed in Case 4.
When it is circulated from the lower part to the upper part of 3, the suspended matter is easily separated from the purification material 42. Therefore, the suspended matter adsorbed on the surface of the purification material 42 can be washed away by passing the bath water having a strong flow force through the purification means 40 in the direction opposite to the normal direction.

Moreover, since the bath water bypassing the filtering means 30 is circulated to the purifying means 40 by the compressor 70 in the state of containing innumerable bubbles, the bubbles promote separation of suspended matters and wash the purifying material 42. The effect can be enhanced.

[0034]

According to the bath water circulation purifying apparatus of the present invention,
The bath water introduced into the circulation path can be circulated to the purifying means without deteriorating the flow force of the bath water by bypassing the filtering means and circulating the bypass. Furthermore, the suspended matter adsorbed on the surface of the purification material can be washed away by passing the bath water having a strong flow force in the direction opposite to the normal direction through the purification means. Moreover, since the bath water bypassing the filtering means is circulated to the purifying means in a state in which the air supplying means causes the innumerable bubbles to be contained, the bubbles promote separation of suspended solids and enhance the cleaning effect of the purifying material. it can.
