浴水の水位が図示点線のように循環ポンプ２への吸込口
６まで達しない状態で循環ポンプ２を運転すると、循環
ポンプ２がいわゆる空運転をして焼損する問題がある。Generally, this type of bath water circulation pump device is as shown in Fig. 3:
Connect the discharge pipe 4 (-1) to circulate the bath water, but if the circulation pump 2 is operated with the water level in the bathtub 1 not reaching the suction port 6 to the circulation pump 2 as shown by the dotted line in the figure, There is a problem that the circulation pump 2 runs dry and burns out.
したがって、浴水の水位が循環ポンプ２を運転するに支

なく、その施工が面倒である。By the way, how to detect the water level of the bath water! 1ij1,
As shown in FIG. 3, a water level pipe 6 connected to the bathtub 1 is provided externally, and when the electrode 7 provided on the water level pipe 6 is short-circuited by the bath water at the set water level, the circulation pump 2 is operated. I am in a position where I can do it. This configuration requires the work of connecting the water level front 6 in addition to the water pump 2 to the bathtub 1. ri° = Nidoori ri 1 rotation 1. The wiring has to be done using a cable, and the installation is troublesome.
また、前記水位管６の市：極７にはトランス等で降圧し

り浴水に印加するという危険性がある。In addition, the voltage lowered by a transformer or the like is present at the electrode 7 of the water level pipe 6, but if the insulation of the transformer or the like is broken, a commercial power supply voltage of 100 cm is applied to the electrode 7. :
There is a danger that the liquid may be applied to the bath water.
本発明はこのような問題に留意し、施工を容易にすると
ともに、電気的安全をはかることを目的とするものであ
る。The present invention takes these problems into consideration and aims to facilitate construction and ensure electrical safety.
上記目的を達ｈνするため、本発明は浴槽に接続された
循環ポンプの吸込側に連通した水位検知器を設け、前記
水位検知器は浴水の圧力に応動する部材と、設定水位時

運転防止スイッチを■する構Ｊ戎としたものである。In order to achieve the above object, the present invention provides a water level detector that communicates with the suction side of a circulation pump connected to a bathtub, and the water level detector includes a member that responds to the pressure of the bath water, and a member that responds to the pressure of the bath water when the water level is set. This system is designed to operate a dry run prevention switch for the pump that is activated by a member that responds to the pump's pressure.

その施工性がよくなるという効朱があるものである。This configuration overloads the airflow prevention switch with a trigger that responds to the pressure of the bath water, so there is no need to contact the electrode for detecting the water level with the bath water, leading to power failures. Since no high pressure is applied to the bath water, it is electrically safe, and there is no need to connect a water level pipe to the bathtub, and the water level detector is installed in the circulation pump, making wiring easy. This has the advantage of improving workability.

0, the circulation pump 11 is connected. A jet pump 12 is inserted into the flow path of the discharge pipe 10,
Inhale air using the negative pressure of the jet pump 12,
Air is mixed into the discharged water (7. Air bubbles are generated in the bath water. Bumping 1 of the circulation pump 11)
3 is a water level detector 1 that communicates with the suction side of the circulation pump 11.
4 and a full water alarm 15 are provided. The water level indicator 14 (as shown in FIG. an actuator 18 that is driven by the displacement of the spring 19, and a spring 19 that moves the tire flam 17 toward the pressure receiving side;
Dry running prevention I in which a reversible VC switch is operated by a lever 2o connected to the actuator 18 and a front NR lever 20.
It consists of an I-switch 21 and a notification switch 22. and! ! The circulation pump 1 switch 21
The alarm switch 22 is connected to the full water alarm 15. Note that an operation switch (not shown) is connected to the power source of the circulation pump 11, and the water adjustment alarm 15 is provided with an IF/OFF switch.

ない。In the configuration described in , -, if the bath water is not filled to the set water level in the bathtub 8, no forces i, tF are applied to the diaphragm 17 of the water level detector 15, and therefore the diaphragm 1Y is moved by the spring 19. The actuator 18 and the lever 20 also move downward, the dry run protection switch 21 is pushed by the lever 2o and is in the OFF state, and the notification switch 22 is released from suppression and is in the OFF state. Therefore, in this state, the circulation pump 11 is '9. I never drive.

を循環させるものである。The water level of the bath water rises one after another, and when it reaches the set water level, the diaphragm 17 of the water level riser 15 resists the force of the spring 19 due to the pressure of the bath water, and is displaced to the position shown in Fig. 2. do. Due to this displacement of diaphragm 1, lever 2
0, when the idle running prevention switch 21 is suppressed, the notification switch 22 is pressed. Therefore, when running idle, 11-switch 2
1 is turned on and the circulation pump 11 is ready to operate, and the notification switch 22 notifies the full water state via the full water alarm 15. After that, the high water alarm 16 was activated,
When taking a bath, etc., the circulation pump 11 is operated to circulate the bath water.

全である。As mentioned above, when the bath water is at the set water level, the pressure of the bath water is used to turn off the switch 11 during dry operation, so the circulation pump does not run dry and the circulation pump is turned off. "Burn out": There are many eels. In addition, unlike conventional dry running prevention switches, the water level is determined by electrodes (no CL is used, so even if there is a disconnection break in a step-down transformer, etc., no EF is applied to the bath water, and electricity is It is safe.
