Description of the Related Art Conventionally, a water absorption section and a water discharge section of a circulation channel are connected to a bath, and a pump, a filtration device using microorganisms, and a heater are provided in the circulation channel so that the bath water in the bath can pass from the water absorption section. There is known a bath water circulation purifying device that sucks in water, filters it with a filtering device, heats it with a heater, and returns it to the bath from a water discharge part. In this bathtub water circulation purifying device of the bathtub, organic substances in the bathtub water are decomposed by microorganisms living on the surface of the filter medium filled in the filtering device to purify the bathtub water of the bathtub, whereby the bathwater is purified over a long period of time. You can take a bath without changing.

発生する。However, since the microorganisms for purification use oxygen to decompose organic substances in the bath water, if oxygen in the water is insufficient, the purification cannot be performed sufficiently. In addition, a so-called jet jet that mixes air by an ejector action is output to the water discharge nozzle that forms the water discharge part of the circulation flow path to supplement oxygen, and mixes air in the bathtub to supply air to the bath water. However, if this is the case, the jet jet will always be ejected, so the bath water will cool, resulting in an extra electricity bill, which is practical in terms of cost. Moreover, since the jet jet is constantly ejected, noise problems occur.

The present invention is invented in view of the problems of the above-mentioned conventional example, supplying air to water only when necessary,
Noise can be minimized, and when cleaning the bath water, the bath water does not cool, the electricity cost is not too high, and it is possible to quickly detect that the filtration device is clogged due to excessive excess of microorganisms. Therefore, it is an object of the present invention to provide a purifying device that can bring the filtering device into a normal state.

Purifies the bath water by decomposing organic matter by
The purified bath water is kept warm by the heater 6 through the water channel switching unit 12 and returned to the bath 1 from the water discharge unit 4. By circulating and purifying the bath water in the bath 1 in this way, the bath water in the bath 1 is maintained in a state where it can be bathed for a long period of time. In the above circulation purification, the dissolved oxygen meter 7 detects the dissolved oxygen quantity in the bath water, and when the dissolved oxygen quantity in the bath water detected by the dissolved oxygen meter 7 is a certain value or more, the solenoid valve 19 is controlled by the control unit 9. It is controlled to be closed, and thus the circulation purification operation is performed in a state where new air is not supplied to the bath water.

とになる。By the way, the microorganisms that purify in the filtration device 5 utilize oxygen to decompose organic substances, so that the oxygen contained in the bath water is consumed, so that the dissolved oxygen in the bath water gradually increases. If the amount decreases and the oxygen in the bath water is insufficient, the purification will not be performed sufficiently and the purification capacity will decrease. Therefore, in the present invention, the dissolved oxygen amount in the bath water is measured by the dissolved oxygen meter 7 and the dissolved oxygen amount is kept at a constant value (for example, 1 pp).
m) or less, the control unit 9 opens the solenoid valve 19,
Air is supplied to the bath water by sucking air from the air pipe 18 by the negative pressure generated in the jet nozzle 4a provided in the water discharge port 4 and ejecting bubbled bath water into the bath water 1, thereby dissolving dissolved oxygen in the bath water. Increase the amount. Here, the solenoid valve 19
The control of the opening time may be performed by a timer, or may be performed until the dissolved oxygen amount measured by the dissolved oxygen meter 7 reaches a certain value or more. In this way, when the amount of dissolved oxygen in the bath water falls below a certain value, air can be automatically supplied into the bath water so that the purification action by the microorganisms in the filtering device 5 can be prevented from decreasing. Further, since the solenoid valve 19 is opened and air is sucked in when oxygen is required, the time during which air is sucked and noise is generated during supply can be extremely shortened. And bathtub water containing air is bathtub 1
Since the time for injecting the water inside is extremely short as described above, it is difficult to cool the water in the bathtub, and as a result, the electricity bill is not additionally charged.

The values may be the same or different), and the controller 9 controls the cleaning device 10 to clean the filtration device 5.

That means that a large amount of oxygen was consumed in the filtration device, and if the oxygen consumption is abnormally large, it can be determined that the microorganisms have excessively increased in the filtration device. Then, when the microorganisms are excessively increased in the filter device 5, the filter device is clogged, the amount of circulating water is reduced, and as a result, the bath water cannot be purified effectively. Therefore, as described above, when the amount of dissolved oxygen becomes a certain value or less within a certain time from the time when the supply of air by the oxygen supply means 8 is stopped, the microorganisms in the filtration device 5 excessively increase. In view of this, the control unit 9 controls the cleaning unit 10 to clean the filtration device 5 to eliminate the clogging of the filtration device 5. In the embodiment shown in the accompanying drawings, the water channels of the water channel switching units 12 and 13 are switched to the cleaning side by a signal from the control unit 9 and the opening / closing valve 16 is opened, so that the bath water sucked from the water inlet 1 is switched to the water channel switching unit 12 → By flowing through the flow path of the water channel switching unit 13 → the lower part of the filtering device 5 → the upper part of the filtering device 5 → the drain pipe 15, the filtering device 5 is washed in the reverse direction from the lower part to the upper part (so-called reverse cleaning). .

To detect the amount of dissolved oxygen in the bathtub water in the bathtub in a bathtub water circulation purification device that sucks the bathwater in the bathtub from the water absorption part, filters it with a filter device, heats it with a heater, and returns it to the bathtub from the water discharge part Is provided with an oxygen supply means for supplying oxygen to the bath water, and the oxygen supply means is controlled so as to supply air into the bath water when the dissolved oxygen amount obtained by the dissolved oxygen meter falls below a certain value. Since a control unit for this is provided, when the amount of dissolved oxygen in the bath water in the bath falls below a certain value, this is detected by the dissolved oxygen meter, and air is supplied into the bath water by the oxygen supply means for filtration. Due to microorganisms in the device Compared to the case where the air can be decomposed effectively and the oxygen is supplied to the bathtub, the air is constantly sucked in and supplied to the bathtub when the bathwater is being spouted from the spout of the circulation channel. The bath water is difficult to cool, the cost of electricity bill can be reduced, and the noise generation time when supplying air can be extremely reduced.
