たものである。This bath water cleaning device is a filtration tank containing a filter for removing suspended matter, an activation tank filled with activated stones for activating the bath water, or a filter, activated stone, activated carbon, or the like. Tanks for filtration treatment such as mixed filtration tanks that mixed the water, heaters for keeping heat to keep bath water at an appropriate temperature, ozone sterilizer for sterilizing bath water, and various devices for circulating bath water It is installed in the forced circulation pipe line of the bath water that is forcibly sucked in and jetted again into the bathtub.

まういわゆる水不足の状態になる場合がある。In such a bath water purifying apparatus, for example, the bath water in the bathtub may be drained, or air may be sucked into the pipeline due to the damage of the apparatus or the like, and the water absorption capacity of the circulation pump may be reduced. There may be a so-called water shortage condition in which the bath water stops flowing in the descending circulation path.
【０００５】循環路中に水不足が生じると、当然のこと
ながら、循環ポンプは空運転して壊れてしまい、また保
温用のヒータが空焚きして装置を損傷させたり火災が発
生する危険すらある。When a water shortage occurs in the circulation path, naturally, the circulation pump runs dry and breaks, and there is a risk that the heater for heating may be dry-burned to damage the device or even cause a fire. .
【０００６】従来は、水不足によって前記したような事

出する水流センサを配備していた。Conventionally, as an abnormality detecting device for preventing the above-mentioned accident due to water shortage, a float switch attached to a circulation pipe of a circulation path as shown in FIG. 6 is used to bath water in the circulation path. A water flow sensor was installed to directly detect changes in flow rate.

って押されながら上下動自在に嵌められたものである。This water flow sensor has a cylindrical case 1 to which a horizontal water inlet 2 and a vertical water outlet 3 are attached.
The float switch 4 is mounted vertically in the inside of the float switch 4. The float switch 4 has a magnet 8 and a float 8 with a magnet 9 mounted on a shaft 7 extending from a lead switch 5 from which two signal lines 6 extend. The lead switch is fitted in a vertically movable manner while being pushed in the direction of 5.

イツチ４はＯＮの状態になっている。In such a water flow sensor, the bath water passes through the water inlet 2 and the float switch 4 is attached to the case 1
It goes in and goes out through the water outlet 3, but when a large amount of bath water is flowing, the float 8 pushes the bath water downwards more strongly than the spring 9 pushes it upwards. Therefore, the float switch 4 is in the ON state because it is lowered and the lead switch 5 is not pushed.

Since the pushing force of the bath water is weakened or disappears at all, it is pushed upward by the spring 9 to push the reed switch 5, the float switch 4 is turned off, and this is transmitted to the control device through the signal line 6. Water shortage is detected, and the equipment is automatically stopped for safety.

作をする欠点があり、またこのセンサに付いた汚れを取
り除くのも難しかった。However, in the case of water shortage detection using a water flow sensor provided in a conventional bath water circulation path, the water flow sensor is directly attached to the bath water circulation pipe. However, there is a defect that the water flow sensor may become dirty or get caught by a foreign object due to long-term operation and malfunction, and it is also difficult to remove the dirt attached to this sensor.
【００１１】さらに水流センサーは、濾過装置が目詰ま
りして循環する浴水の量が減ってもＯＦＦとなる。Further, the water flow sensor is turned off even if the amount of circulating bath water is reduced due to clogging of the filter device.
【００１２】このため、水流センサ４のばね９を強くし
ておくき、濾過装置の目詰まりの場合のように多少水量
が減った程度ではＯＦＦとならず、水不足状態の場合の
ようにかなり水量が減った場合に初めてＯＦＦとなるよ
うにしている。For this reason, the spring 9 of the water flow sensor 4 should be made strong so that it will not turn off when the amount of water has decreased a little as in the case of clogging of the filtration device, but rather the amount of water will be rather large as in the case of a water shortage condition. It is designed to be turned off only when the number decreases.

てしまう欠点もあった。However, since the water flow sensor cannot adjust the spring pressure with high accuracy, it is difficult to identify whether the water flow sensor is turned off due to clogging of the filter or turned off due to lack of water. Since it is operated, there is also a drawback that even if the filter device is clogged to some extent, it is judged to be abnormal and the operation of the device is stopped.
【００１４】本発明は、前記したような従来技術の欠点

る。That is, according to the present invention, the bath water is forcibly circulated by a circulation pump, and in the circulation path, dirt is filtered in a filtration tank, heat is maintained by a heater, and sterilization is performed by ozone. In the bath water purifying device, a water level detection device is provided in a closed tank provided in the circulation path in order to detect that the flow of the bath water in the circulation path has stopped and a water shortage has occurred. The bath water cleaning device is a bath water cleaning device in which the water level detection device is a float switch in which a float is floated on the water surface in the tank.

水の流量で検出している場合のように濾材の目詰まりと
の混同がない。The present invention is constructed as described above, and the lack of water is detected by detecting the water level in the closed tank. Since the water level in the tank does not change due to the clogging of the filter medium, the conventional flow rate of bath water is used for detection. There is no confusion with the clogging of the filter media as it does when.

易に取り除け、したがって、汚れがついたために誤動作
しにくい。Further, the float switch for detecting the water level in the closed tank detects the water level in the tank by directly floating the float on the water surface of the closed tank and moving it up and down according to the water level. It is difficult for dirt to attach, and the dirt can be easily removed by opening the lid of the closed tank. Therefore, malfunction does not easily occur due to dirt.

なるので、水不足を正確に検出できるようになる。Further, since a large amount of bath water is stored in the tank to give a large buoyancy, the float of the float switch can be made larger and heavier than the conventional one, whereby dirt is attached to the movement of the float. Since the influence of is reduced, the water shortage can be accurately detected.

1 is loaded with a spool filter 27, and the bath water in the filtration tank 11 flows as shown by the arrow, and after being filtered by the filter 27, a filter pipe 28 having numerous holes is provided.
Go out through the tank.
【００２８】濾過タンク１１の上部開口は着脱自在の蓋

２９に、タンク内の水位で水不足を検出する水位検出装
置としてのフロートスイツチ２２が取り付けてある。The upper opening of the filtration tank 11 is closed by a detachable lid 29, and as will be described later in detail, the lid switch 29 has a float switch 22 as a water level detecting device for detecting water shortage at the water level in the tank. Is attached.

理もする。Reference numeral 30 denotes a filter medium tank. The filter medium tank 30 is loaded with granular filter medium 32 such as activated carbon or activated stone packed in a filter medium bucket 31 to adsorb and activate small dirt in the bath water at the same time. It is also treated according to the ability of the filter medium, such as chemical conversion.

ロートスイツチ２２を取り付けるのが好ましい。Thus, the closed tank is the filtration tank 11
When there are two and the filter medium tank 30, the circulation pump 1
It is preferable to attach a float switch 22 as a water level detecting device to the closed tank on the upstream side of 2.
【００３１】何故なら、水不足となった場合には、循環
ポンプ１２の上流側にある密閉タンクの方が早く水位が
下がり始め、水不足を素早く検出できるからである。This is because, in the case of water shortage, the water level in the sealed tank upstream of the circulation pump 12 starts to drop earlier, and the water shortage can be detected quickly.

る。The operation of the float switch 22 thus attached to the filtration tank 11 will be described with reference to FIG. 4. When the apparatus has no abnormality, the state shown in FIG. Since the float is on the upper side, the magnet switch 35 operates, and a signal indicating that there is no abnormality in the device is output from the signal line 36.
【００３４】これに対して、水不足となると（ａ）図に

から出る。On the other hand, when the water becomes insufficient, the state shown in FIG. 7A is reached, and the water level of the filtration tank 11 is lowered and the float 34 is located at the lower side, so that the magnet switch 35 is cut off and the water is insufficient. The signal indicating that the signal line 36
Get out of.
【００３５】フイルタ２７に汚れが沢山付いて目詰まり
した場合、浴水の流量は減るものの濾過タンク１１の水
位は変わらないのでフロート３４の位置は変わらず、フ
イルタ２７の目詰りを水不足と誤って検出しない。When the filter 27 is clogged with a lot of dirt, the flow rate of the bath water is reduced but the water level of the filtration tank 11 does not change. Therefore, the position of the float 34 does not change and the clogging of the filter 27 is erroneously determined to be insufficient. Not detected.

位を検出するのが好ましい。The water level of the filtration tank 11 may be indirectly detected by the water level of a water level detection pipe attached to the side of the tank, but in this case, the detection pipe is clogged with dirt and the detection tends to be inaccurate. It is preferable to directly detect the water level in the tank with the float 34 floating on the water surface like the float switch 22 of this embodiment.

にくくするのが好ましい。Further, even if dirt is attached to the float switch 22, it can be easily cleaned by removing the dirt by opening the lid 29 of the filtration tank 11, so that it can be operated accurately at any time. Float 3 has a large amount of bath water and can be given a large buoyancy.
It is preferable to make 4 large and heavy so that it is not easily affected by the adhesion of dirt.
【００３８】フロート３４の大きさ及び重さの大小と、
これが水位に応じて上下動する際の力の大きさのとの関
係は図５に示す通りである。The size and weight of the float 34,
The relationship with the magnitude of the force when this moves up and down according to the water level is as shown in FIG.

Therefore, when the float 34 is large and heavy, even if it is slightly soiled, it will not be affected by the vertical movement.
