しないようにしている。2. Description of the Related Art Conventionally, in this type of bath unit, a bathtub water circulation circuit connected to a bathtub,
A circulation pump, a filtration tank, and a biological filter bed tank are sequentially arranged,
A circulation pump inhales bath water containing hair, dust, dirt, soap, etc. in the bath, removes hair, dust, dirt, etc. in the filtration tank, and then removes soap and organic matter, which are nutrient sources for microorganisms, in the next step. The water is removed from the biological filter tank and sent out into the bath, and by repeating this, the bath water is purified, and various bacteria are prevented from propagating in the bath.

めには、常に一定の溶存酸素を確保しておく必要があ
る。By the way, in the biological filter bed, since organic substances, which are sources of propagation of various bacteria, are removed by the action of microorganisms, a certain amount of dissolved oxygen is always secured in order to maintain the purification action by the microorganisms. You need to do it.

排水するようにしたものが提供されている。Normally, dissolved oxygen can be naturally secured by operating the circulation pump to circulate the bath water, but if the circulation pump is stopped for some reasons, such as when the house is away. The hot and cold water stays in the biological filter tank and oxygen is no longer supplied, and as a result, dissolved oxygen becomes insufficient, resulting in an anaerobic state and a bad odor.
In order to avoid such trouble occurrence, in the conventional technology,
If a drainage channel is connected to the biological filter bed tank, a drainage valve is installed in the middle of the drainage channel, and if the circulation pump is stopped, this drainage valve is opened and hot water that accumulates in the biological filter bed tank passes through the drainage channel. It is provided that is then drained.

が発生する。However, when the circulation pump fails, or when air is mixed in the circulation pump to cause a so-called air lock phenomenon,
Since the bath water is no longer circulated in the circulation path, hot water accumulates in the biological filter tank and dissolved oxygen is deficient, as a result of which the circulation pump is stopped. appear.

駄な電力消費を強いられことになる。Further, when the circulation pump is stopped for reasons such as when the house is absent, the offensive odor can be suppressed by draining the hot water that remains in the biological filter tank as described above. However, when the drainage state in the biological filter tank is continued for a long time, the inside of the tank is dried and the microorganisms are killed.
Therefore, it takes extra time to cure the microorganisms again until the biological filter tank exhibits the required cleaning action. In order to prevent this, the circulation pump must be continuously operated even when the user is away from the bathtub, resulting in wasted power consumption.

ようにすることを第２の課題とする。In view of the above circumstances, the present invention is intended to prevent the bath water from being circulated due to the failure of the circulation pump, the occurrence of an air lock, etc., and the hot and cold water to remain in the biological filter tank, resulting in a shortage of dissolved oxygen. Even if such a situation occurs, the first issue is to reliably prevent the generation of a bad odor, and due to various circumstances, stop the circulation pump to drain hot water in the biological filter tank for a long time. Even if the biological filter bed is used again to purify the bath water from the existing state, the biological filter bed should be able to recover to the state where it can perform the required cleaning action within a short time. This is the second issue.

When the bath water is no longer circulated due to an abnormality such as an air lock, the water flow sensor detects that the water flow has disappeared, and the detection output is input to the drainage control means. The drainage control means activates the drainage means in response to the detection output, so that the drainage means drains the hot water in the biological filter tank together with the hot water in the bathtub . For this reason, the retention of hot and cold water in the biological filter tank is removed and an aerobic state is secured, so that the generation of a bad odor is avoided.

As a result, water is intermittently replenished in the biological filter bed tank to prevent drying, so even if the circulation pump is stopped for a long time, the microorganisms in the biological filter bed tank will survive and will be circulated again. When the pump is started and circulation of bath water is started, the inside of the biological filter tank is restored to a state where the required purification action is exhibited within a short time.

Since water is intermittently replenished into the biological filter bed tanks 14a and 14b through the hopper 36 and the three-way valves 12a and 12b to prevent drying, the biological filter bed is stopped even if the circulation pump 6 is stopped for a long time. The microorganisms in the tanks 14a and 14b survive as they are. Therefore, when water is poured into the bathtub 2 again to start circulating the bathwater, the inside of the biological filter beds 14a and 14b is restored to a state where the required purifying action is exerted within a short time.

In the downstream portion of 0, the backwash water passage valve 54 is opened, and in the downstream portion of the biological filter bed 14, the three-way valve 56 is switched to the side for introducing the backwash water. Thus, the hot and cold water sucked from the bathtub 2 into the circulation path 4 flows into the lower part of the filtration tank 10 via the water passage valve 54, and into the lower part of the biological filter bed tank 14 via the three-way valve 56. . The filter tank 10 and the biological filter bed tank 14 are washed with hot water flowing in the opposite direction. The hot and cold water that has passed through the tanks 10 and 14 flows into the backwash drainage channel 52 via the three-way valves 48 and 50 at the upstream portions of the tanks, and is drained through the drainage channel 52.

In response to the detection output from the water level sensor 46, the power supply to the circulation pump 6 and the sterilizer 16 is stopped, the drain valve 62 that constitutes the drain means 58 is opened, and the three-way valves 48 and 50 are turned on. Switch to the backwash side. As a result, the hot and cold water in the biological filter bed tank 14 is drained by the backwash drainage channel 5.
Since it is opened to the atmosphere via 2, the drainage valve 62 flows from the lower three-way valve 56 through a part of the circulation path 4 into the drainage path 60.
Drains smoothly through. For this reason, retention of hot and cold water in each biological filter bed tank 14 is removed, and an aerobic state is secured. In addition, this drainage control means 42 switches the three-way valve 48 to the backwash side and opens the water passage valve 54 during drainage of the filtration tank 10 to open hot water in the filtration tank 10 to the circulation path 4. The water is drained from the drain of the bathtub 2 through a part.

Regardless of whether the circulation pump is operating
Since it is detected, it stays in the biological filter tank.
The hot and cold water can be reliably discharged, and the generation of a foul odor can be reliably avoided. Especially, bathtubs that are no longer used
The hot water inside is also discharged together with the hot water inside the biological filter bed tank.
Therefore, it is not necessary to perform the drainage work separately, and it has excellent operability.
It is something. According to the second bath unit of the present invention,
Do not drain the hot water in the bathtub regardless of the operation of the circulation pump.
That is, it stays in the biological filter tank when the bath is not in use.
Since hot water is discharged, the discharge is surely performed and the
Occurrence can be reliably avoided.

常時継続するのに比べて、消費電力も僅かである。According to the third bath unit of the present invention, in addition to the above effects, for example, due to various reasons, the circulation pump is stopped and the hot and cold water in the biological filter tank is drained for a long time. Even when the biological filter bed tank is used again to purify the bath water from the state, the survival of the microorganisms is maintained as it is, so the biological filter bed tank exhibits the required cleaning action within a short time. You can recover to what you can. Further, in order to maintain the survival of the microorganisms in the biological filter tank, only the water replenishing operation is intermittently performed, and therefore the power consumption is small compared to the case where the circulation pump is continuously operated.
