て外部に排出される。<Operation> When the bath water level falls below a certain level, the water level detection switch 7 is turned off and the timer of the backwash timer circuit 8 is reset via the control circuit. This allows the timer to be used again. Then, after that, when the water level in the bathtub becomes a certain level or higher, the water level detection switch 7 is turned on, and the backwash timer circuit 8 and the pump drive unit 9 are electrically connected to the drive power source via the operation switch S and can be driven by the control circuit. Therefore, when the operation switch S is turned on in this state, the pump drive unit 9 is driven via the control circuit to rotate the pump P,
The water in the bathtub 1 is transported. Also, the timer of the backwash timer circuit 8 is activated, and the passages 2, 6, 6 from the bathtub 1 are held for a certain time.
The a and 6b are arranged in the backwash direction of the filter 5. Therefore, the bath water flows through the filter 5 in the direction opposite to the filtering direction, and the filter 5 is backwashed and discharged to the outside.
逆洗タイマー回路８のタイマーによる一定時間が経過す
ると、タイムアップにより浴槽１からの通路２、６、6
a、6bが濾過器５による通常の濾過方向になる。以後、
運転スイッチＳがオフするまで通常の濾過運転となる。After a certain period of time by the timer of the backwash timer circuit 8, the passages 2, 6 and 6 from the bathtub 1 are timed up.
The a and 6b are in the normal filtering direction by the filter 5. After that,
Normal filtration operation is performed until the operation switch S is turned off.

し、通常の濾過が行われる。Even if the operation switch S is turned off, the backwash timer circuit 8 is not reset unless the bath water is drained and the water level detection switch 7 is turned off. Therefore, when the operation switch S is turned on again without being drained. The timer of the backwash timer circuit 8 does not operate, and only the pump drive section 9 is driven to perform normal filtration.

洗タイマー回路８も作動しない。When the bath water level falls below a certain level, the backwash timer circuit 8 is reset, but at the same time, the electrical connection to the drive power source via the operation switch S of the backwash timer circuit 8 and the pump drive unit 9 is turned off. Therefore, at this time, even if the operation switch S is turned on, the pump P is not driven and the backwash timer circuit 8 is not operated.
以上のように、逆洗タイマー回路８のタイマーは浴槽水
位が一旦一定水位未満の水位に排水された後、再び一定
水位以上の水位に給水された場合だけ作動可能となるの
で、実質的には浴槽水が綺麗な水に入れ替えられた場合
に逆洗タイマー回路８の作動が可能ということになる。
勿論、浴槽１内に多少の残水が残った状態で給水が行わ
れた場合も含むことにはなる。As described above, the timer of the backwash timer circuit 8 can be operated only when the water level of the bathtub is once drained to a water level lower than the fixed water level, and then again supplied to the water level above the fixed water level. This means that the backwash timer circuit 8 can be operated when the bath water is replaced with clean water.
Of course, this also includes the case where water is supplied with some residual water remaining in the bathtub 1.
よって結局、浴槽水による濾過器５の逆洗は、浴槽水が
新しく入れ替わった後の最初の濾過運転時だけに、濾過
動作に先だって一定時間清浄な水ないし湯で行われるこ
とになる。よって濾過器５は清浄水で十分効果的に且つ
確実に綺麗に洗浄される。Therefore, after all, the backwashing of the filter 5 with the bath water is performed with clean water or hot water for a certain period of time prior to the filtering operation only at the first filtration operation after the bath water is newly replaced. Therefore, the filter 5 is sufficiently effectively and surely cleaned with clean water.

がなされるだけで、逆洗が行われない。An example of operation control will be described with reference to the control circuit of FIG. 2 and the time chart of FIG. In FIG. 2, the water level detection switch 7 supplies water (hot water) to the bathtub 1, and the water level in the bathtub 1 is a regulated water level, in fact, a water level at which a circulation fitting for connecting the circulation path 2 to the bathtub 1 is provided. It turns on.
This turning on excites the relay coil R 1 , and this excitation closes the relay contacts R 11 and R 12 . As a result, the backwash timer circuit 8 and the pump drive unit 9 are electrically connected to the drive power source via the operation switch S. Therefore, when the operation switch S is turned on while the relay contacts R 11 and R 12 are closed, the backwash timer circuit 8 and the pump drive unit 9 start operating. When the switch S is turned on, the backwash timer circuit 8 counts a fixed time by a built-in timer, and until the count expires, the three-way valves V 1 and V 2 are respectively moved to the auxiliary path 6a and the drain path 6b side. Connect to form a backwash channel as shown by the dashed arrow. Then, when the count is completed, the connection of the three-way valves V 1 and V 2 is switched to form a filtration flow path indicated by a solid arrow. The timer of the backwash timer circuit 8 keeps the time-up state unless the water level detection switch 7 is turned off after the bath water is drained after the time is up. And a reset signal circuit when the water level detection switch 7 is turned off.
A reset signal is input through 10 and the timer is reset. That is, once the time is up, as long as the bath water is not drained and the water level detection switch 7 is not turned off, no matter how much the operation switch S is turned on again, only the filtering operation is performed and the backwashing is not performed.

向に構成する。Now, when the bath water is drained and the water level detection switch 7 is turned off, the timer of the backwash timer circuit 8 is reset via the reset signal circuit 10. Next, when the hot water or the water is newly supplied to the bathtub 1 and the water reaches a specified water level or higher, the water level detection switch 7 is turned on, and the backwash timer circuit 8 and the pump driving unit 9 make the relay coil R 1 and the relay contact of the control circuit. R
11 and R 12 electrically connect to the driving power source via the operation switch S. Therefore, when the operation switch S is turned on, the pump drive unit 9 is driven to start the circulation of bath water, and the timer of the backwash timer circuit 8 is started to switch the three-way valves V 1 and V 2 for a certain period of time to switch the passage. In the backwash direction of the filter 5.

し、運転スイッチＳのオンによる運転が可能となる。Part of the circulating water flows through the filtering circuit 6 in the direction of the broken arrow,
The filter 5 is backwashed and the backwashed water is discharged from the drainage channel 6b. Since the filter 5 is backwashed with freshly supplied clean bath water, it can be washed sufficiently cleanly. When the timer of the backwash timer circuit 8 times out, the three-way valve V 1 ,
V 2 is switched, and the normal filtering operation of the filter 5 is performed. This filtering operation continues until the operation switch S is turned off. Then, if the operation switch S is turned on again without draining the bath water thereafter, the normal filtering operation is performed. When the bath level water is drained and the water level detection switch 7 is turned off, the timer of the backwash timer circuit 8 is reset, and when the water level detection switch 7 is turned on again by water supply, the relay contact R 11 via the relay coil R 1 again, R 12 is turned on, and operation can be performed by turning on the operation switch S.
このように本実施例では、浴槽水が新しい水と入れ替わ
った後の最初の運転開始時に１回だけ逆洗が濾過に先だ
って行われる。Thus, in this embodiment, the backwashing is performed only once before the filtration at the start of the first operation after the bath water is replaced with new water.

You can take action. Therefore, the filter can also be backwashed only with fresh clean water to clean the filter sufficiently cleanly. Further, when the water is not clean water, the backwash causes contamination from the reverse direction of the filter. However, in the present invention, such inconvenience can be surely eliminated and the filter can be surely washed. Moreover, since the filtration operation is started immediately after the backwashing, there is no possibility that bacteria and the like will propagate during that time and the backwashing effect will be lost.
