吸い込まれる。 The pumped tap water enters the filter tower 7 and passes through the filter media 1.
After washing 4 with water, it is discharged from hose nipple 15 via pipe 6. Since the amount of tap water pumped from the hose nipple 3 is set to be larger than the amount discharged from the hose nipple 15, the water level in the filtration tower 7 gradually increases due to the difference.
The water passes through the valve 8 and check valve 12 provided in the upper part of the filtration tower 7, and then flows out from the tip of the overflow pipe 13. If this leak is confirmed, immediately stop the pumping of tap water. This causes a siphon phenomenon, and the wash water in the filter tower 7 is ejected from the hose nipple 15 of the pipe 6. At the same time, air is actively sucked into the filter tower 7 through the check valve 10, the intake pipe 11, the T-type siphon pipe 34, the main pipe 9, and the filter tower 7.

This air bubbling continues until the wash water in the filtration tower 7 is discharged from the hose nipple 15 by a siphon effect and is reduced to the water level at the filtration tower attachment part of the pipe 6. On the other hand, as the washing water is discharged from the hose nipple 15, air accumulates in the upper part of the filtration tower 7, and when the washing water from the hose nipple 15 is completely discharged, the air is sucked from the check valve 10. stops, and the siphon phenomenon ends. Air suction stops when the sound of air suction disappears, or when the hose nipple 15 of pipe 6 stops.
This can be confirmed by the fact that the washing water has finished discharging. This completes the first backwashing.

の逆洗を行なうことができる。 Repeat this operation several times. The filter medium 14 is thereby regenerated. In this way, in this embodiment as well, the filter medium can be effectively backwashed in the same manner as in the first embodiment.
一方、１台のろ過装置で２層以上の浴槽の循環
ろ過を行なう場合は、当然のこととして、当該ろ
過装置のモーターポンプ４′には、当該２層以上
の浴槽湯をろ過するに必要な条件を与えてある。 On the other hand, when performing circulation filtration of bathtubs with two or more layers with one filtration device, it is natural that the motor pump 4' of the filtration device has the necessary power to filter the bathtub water with two or more layers. Conditions have been given.
従つて、入浴人員の少ない時間帯で一部の浴槽
のみ使用したい時は、循環ろ過すべき湯の量は当
該モーターポンプが処理できる量より少ない。 Therefore, when it is desired to use only a part of the bathtub during a time when there are few bathers, the amount of hot water to be circulated and filtered is less than the amount that the motor pump can process.
そのような状態で循環ろ過をすると、湯の流速

湯の温度が高温になつて入浴者に危険を与える等
の支障が生ずる。 If circulation filtration is performed in such a state, the flow rate of hot water will increase, the pressure in the return pipe 26 will become high, and it will become unstable, creating a large eddy current in the bathtub, and due to the diameter of the pipe, the amount of suction and discharge will be reduced. If the balance is lost and the filtered water is heated by the steam suction method, the amount of suction described above will increase, causing problems such as the temperature of the filtered water rising to a high temperature and posing a danger to bathers.

て作用せしめる。 The bubbling promoting tube 32 according to the present invention eliminates such problems by adding a bypass circuit as in the conventional case.
Alternatively, it can be removed without complicated operations such as switching or adjusting valves. That is, by adjusting the valve 33 so that the pressure is the same as the pressure in the filtration tower during full-tank filtration, the hot water above a predetermined height in the filter medium chamber 18' of the filtration tower 7' can be refilled. The hot water is returned to the hair catcher 5' and treated as having twice the amount of hot water, and the motor pump 4' is operated in the same manner as when filtering the entire bathtub.

決できる。 Furthermore, when operating the filter after replacing the bathtub water, cleaning the hair catcher 5', or repairing or inspecting the filter, it is a matter of course that the Tube 1 leading to hair catcher 5' and bathtub 1
6' must be filled with water. If there is no water in the suction path, that is, if air remains, the motor pump 4' will not suck in the raw hot water and will run idly, eventually generating heat and breaking down.
In order to prevent such failures, conventional methods have been to either open the top cover of the hair catcher 5' and supply tap water, or
A water supply port is provided at the highest point of the pipe 16', and tap water is supplied from there, which is a troublesome process. Such difficulties can be easily solved by the bubbling promotion tube 32 according to the present invention.

きる効果もある。 That is, when it is necessary to supply water to the suction side of the motor pump 4', by opening the valve 33 of the bubbling promotion pipe 32, water from the upper part of the filter tower 7' can be drained from the filter medium flow prevention outlet 31 to the hair catcher 5. ' and pipe 16' can be immediately supplied with water (conventionally there is a valve 161 in the middle of pipe 16 that can be opened and closed)
is inserted, and when performing the above-mentioned work such as after cleaning the hair catcher 5', the valve must be closed in advance. ) Both can be filled with water. In other words, the bubbling promoting pipe 32 acts as a water supply mechanism for supplying water to the suction side of the motor pump 4', thereby eliminating the troublesome work described above.

After circulating and filtering the bath water, the three-way valve 151
By adjusting the opening of the washing machine, only the amount of water needed for washing is sent to the washing machine, and the remaining amount of water can be circulated and filtered. In addition, when cleaning the filter medium of the bathtub circulation filter for small bathtubs shown in Fig. 3, the three-way valve 15
If 1 is fully opened to the washing water side, that is, to the drainage side, it can perform the same function as the hose nipple 15 without causing any problems.
