Description of the Related Art Recently, hot water in a bathtub is pumped up by a circulation pump to forcibly circulate through a circulation passage provided with a cleaning tank such as a filtration tank, a sterilizer and a heater for keeping heat, and at the same time as the cleaning processing. The warm water is jetted again into the bathtub,
A so-called 24-hour bath water purifying device has been developed that can be comfortably bathed at any time.
【０００３】この浴槽湯の清浄化装置の濾過タンクには
多孔質の粒状濾材が充填されており、、運転を続けると
汚れが付いて目詰まりし、湯の循環量が減って清浄化の
能力が落ちてしまうので、時々濾過タンクから濾材を取
り出して洗わなければならなかった。The filtration tank of this bath water purifying apparatus is filled with a porous granular filter medium, and when it is continuously operated, it becomes clogged with dirt and the circulation amount of the hot water is reduced, resulting in a cleaning ability. I had to remove the filter material from the filter tank and wash it occasionally.

クから取り出さないでも自動的に洗えるように、濾過タ

材を自動的に洗ういわゆる逆洗機構を取り付けた装置が
多く開発されるようになった。Since it is troublesome to wash the filter medium and at the same time, it is not favored for the dirty work, so recently, when the filter tank is cleaned with hot water so that the filter medium can be automatically washed without removing it from the filter tank. Many devices equipped with a so-called backwashing mechanism that automatically rinses the filter medium by flowing it in the opposite direction have been developed.

【発明が解決しようとする課題】従来の逆洗機構は濾過
タンクに湯を単に逆流するものであったが、それほど圧
力の高くない湯を単に逆方向に流すだけでは、層を作っ
ている濾材は層が崩れてばらばらにはならないので、そ
れほど効果的汚れを取り除けなかった。In the conventional backwashing mechanism, the hot water is simply backflowed to the filtration tank. However, if the hot water having a not so high pressure is simply swept in the reverse direction, the filter medium forming the layer is formed. Couldn't remove the dirt so effectively as the layers wouldn't collapse and fall apart.

比較的大きく重いので濾材の層を振動により崩してばら
ばらにするのは難しく、またこの濾材に振動を与えるた
めの装置は複雑で高価になると同時に、故障し易くメン
テイナンスが大変である。Therefore, it has been considered to backwash the filter medium by vibrating it with ultrasonic waves or the like while destroying the layer. However, since the filter medium is relatively large and heavy, it is difficult to disrupt the filter layer by vibration to separate it. Also, the device for vibrating the filter medium is complicated and expensive, and at the same time, it is easy to fail and maintenance is difficult.

ばらばらにしながら逆洗する装置である。Therefore, as a conventional technique, a device as shown in FIGS. 3 and 4 has been proposed as a device having a simple structure, low cost, and easy maintenance. FIG. 3 shows the state during the cleaning process, and FIG. 4 shows the state during the backwash. In backwashing in FIG. 4, air is stored in the air tank 114 together with hot water into the filtration tank 105 from the opposite direction, and the backwashing is performed while the layers of the filter medium are broken down by the stirring force of the air to separate them.
