し、パツキンや軸受に損傷を起こす弊害がある。[Prior Art] The bathtub device having the hot water circulation means shown in FIG. 2 operates continuously for 24 hours to filter the hot water in the bathtub.
It can be heated and bathed at any time of the day. However,
In this bathtub device, the drain cap may open slightly for some reason, and the hot water in the bathtub may gradually drain out. In this case, when no one is taking a bath late at night or early in the morning, the hot water level may drop and the circulation pump may draw in air. In this state, the pump is in idle operation and the load on the pump is reduced, which causes damage to the bearing due to an abnormal increase in the number of revolutions over a certain period of time. Furthermore, since this type of bathtub device uses towels in the bathtub, accidents frequently occur in which towels or the like are sucked into the suction pipe and become clogged on the suction side. In this case, the circulation pump is no longer able to circulate hot water, and the friction heat generated by the continuous stirring of the same water inside the circulation pump causes the temperature of the pump to rise, causing damage to the seals and bearings. be.

74894号公報）。 Also, the vertical movement of the float installed in the waterway,
A device has also been developed that uses a reed switch, which is a magnetic sensing switch, to operate the pump only when the waterway is filled with water.
Publication No. 74894).
しかしながら、これ等従来の装置は、 水がないときにポンプの運転を停止する。 However, these conventional devices Stop pump operation when there is no water.
水がある時にポンプを運転する。 Run the pump when there is water.
水が流れるときにポンプを運転する。 Run the pump when water flows.
ものである。It is something.
通常の水のポンプは、水路内に水があると必ず
送水されるが、この考案の浴槽装置は、循環ポン
プの使用形態からしてポンプ内に水があつても、
温水が循環されないという、普通のポンプでは発
生しない特有の状態が発生する。 A normal water pump always pumps water when there is water in the waterway, but the bathtub device of this invention, due to the way the circulation pump is used, does not pump water even if there is water in the pump.
A unique situation occurs that does not occur with ordinary pumps: hot water is not circulated.
即ち、人が入つてタオル等を使用する浴槽は、

にはできない。 In other words, bathtubs where people enter and use towels, etc.
It is impossible to prevent towels, etc. from being inhaled by mistake.
It often happens that the towel gets sucked in and the water line gets clogged. It seems that towel inhalation can be prevented by blocking the open end of the suction pipe with a water-passing plate. However, this water passage plate allows foreign matter contained in the hot water in the bathtub to
Especially since the hot water in the bathtub contains a large amount of hair,
As this builds up, the water passage plate must be removed from the suction pipe and cleaned almost every day, and the water passage plate must be constructed to be extremely easy to remove and attach, or it must be omitted. A water passage plate that is easy to attach and remove is likely to fall off when touched by feet or the like during bathing, and a suction pipe without a water passage plate cannot completely eliminate inhalation of towels, etc.
更に困つたことに、この種の装置は、循環ポン
プがケーシング内に内蔵されるため、タオル等が
詰まつてこれが内部に強く吸着されると、これを
除去するのに著しく手間が掛かる欠点がある。 A further problem is that this type of device has a circulation pump built into the casing, so if towels or the like become clogged and get strongly absorbed inside, it takes a lot of effort to remove them. be.

たときにも循環ポンプの運転が停止される。 For this reason, when the water in the waterway is drained and air is taken in, the water flow float descends under its own weight and the operation of the circulation pump is stopped, and even if the waterway is filled with warm water, , the operation of the circulation pump is also stopped when this does not circulate. Therefore, if hot water in the bathtub is accidentally drained, the circulation pump will stop, and furthermore, if hot water in the bathtub is sucked into the introduction hose and the circulation of hot water is stopped, the circulation pump will also stop. Pump operation is stopped.
このことは、この種の装置にとつて極めて大切

とが解決されない限り、誰もが便利に使用できる
浴槽装置は実現できない。 This is an extremely important characteristic for this type of device, and if a bathtub device were to break down every time towels, etc. The bathtub cannot be used at all until it is repaired, which is extremely inconvenient. The condition in which towels and the like are sucked into the introduction hose is a condition peculiar to this type of device, but unless this problem is solved, it will not be possible to realize a bathtub device that anyone can conveniently use.
この考案の浴槽装置は、空気吸入による空転に

た針金等を挿入しても簡単に引き出すことができ
て、すこぶる便利に使用できる。 The bathtub device of this invention does not stop at idling due to air intake, but has an extremely simple structure, and the circulation pump stops when it is clogged due to inhalation of towels, etc., so the towels are not sucked in extremely strongly, and the circulation pump is stopped. For long, thin towels, the circulation pump will stop while part of the towel is outside the bathtub, so you can easily clear the blockage by pulling on the end of the towel. Since it will not be adsorbed under strong conditions, even if a wire with a hook-shaped tip is inserted into the introduction hose, it can be easily pulled out, making it very convenient to use.
