()Response 1. f operation 1. 11 after a certain period of time
A timer circuit 5 is provided which forcibly inverts the output signal of the liquid level detection circuit 3 and cancels the self-operation before the next inversion of the output signal of the liquid level detection circuit 3. In this embodiment, the timer contact 5a of the timer circuit 5 is connected between the high liquid level detection electrode 2b and the common electrode 2c, and the timer time T of the timer circuit 5 is used for setting the timer time. It can be changed freely in Volume 6. In addition, the pump 4 consisting of the pump body 4a and the drive motor 4b is connected to a three-phase electric @AC via an electromagnetic contactor 7.
is applied, and the electromagnetic contactor 7 is controlled by the output contact 3a which is the output signal of the liquid level detection circuit 3. Furthermore, water is supplied to the water tank 8 via a ball tap 9. FIG. 2 is a time chart illustrating the operation of the above embodiment, in which (a) shows the liquid level in the water tank 1, and (b) shows the state of the output contact 3a of the liquid level detection circuit 3. Figure (c) shows the state of the timer contact 5a of the timer circuit 5. In the figure, the dotted line indicates the operation of the conventional example without the timer circuit 5. As is clear from Figure 0, in this embodiment, the low liquid level is set by the liquid level detection means 2, and the high The liquid level is set by the timer time T of the timer circuit 5, so that the high liquid level can be easily changed, and the liquid level detection means 2 can be set by the timer time T of the timer circuit 5. i! Water [
The variation range of water storage amount and water residence time in step 1 can be easily adjusted according to the situation, and it is possible to easily respond to the water usage situation. In addition, in the embodiment, the timer contact 5a is connected between the high liquid level detection electrode 2b and the common electrode 2c without changing the liquid level detection circuit 3, and by turning on the timer contact 5a, the high liquid level is detected. Since the same detection signal (short-circuit signal) as when high liquid level is detected by the level detection electrode 2b and the common electrode 2c is input to the liquid level detection circuit 3, if the timer circuit 5 is not operated, , the liquid level can be controlled only by the liquid level detection means 2, similar to the conventional example. FIG. 3 shows another embodiment, in which a timer contact 5a is inserted into the wiring of the low liquid level detection electrode 2a in a liquid level control device similar to the embodiment shown in FIG. 5 is a time chart showing the operation of the above embodiment. In this embodiment, the low liquid level is set by the timer circuit 5, and the high liquid level is set by the liquid level detection means 2, and the timer contact ζ5a is the liquid level detection means 2. A signal similar to that used when detecting a low liquid level by the means 2 is input to the liquid level detecting circuit 3, and the pump 4 is controlled based on the liquid level detecting means 2 and the timer contact 5a to drain water from the water tank 1 [8° It is designed to pump water to Note that the output of the liquid level detection circuit 3 is formed by an output contact 3a' which is a switching contact. FIG. 5 shows still another embodiment, in which the liquid level control device is applied to the water tank 1 for drainage, and FIG. 6 is a time chart showing the operation of the above embodiment, and the configuration and operation are as follows. This is the same as the embodiment shown in FIG. FIG. 7 shows still another embodiment, which is formed by inserting a timer contact α5a into the wiring of the low liquid level detection electrode 2a in a liquid level control device similar to the embodiment shown in FIG. FIG. 8 is a time chart showing the operation of the above embodiment, and the configuration and operation are the same as those of the MS3 diagram embodiment. Effects of the Invention The present invention is configured as described above, and is operated in response to the output signal of the liquid level detection circuit, forcibly inverts the output signal of the liquid level detection circuit after a certain period of time, and also self-operates. A timer circuit is provided that is released before the next inversion of the output signal of the liquid level detection circuit, and the liquid level detection electrode detects either a low liquid level or a high liquid level, and the liquid level detection circuit output detects either a low liquid level or a high liquid level. Even if the pump is activated, the timer circuit stops the pump after a certain period of time without waiting for the other liquid level to be detected, making it extremely easy to operate without having to adjust the liquid level detection means. The variation range of the liquid level and the amount of water stored can be changed, the residence time of water in the tank can be easily changed depending on the situation, and the effect can be sufficiently adjusted to the water usage situation or water drainage situation.

とで構成された液位制御装置。(1) A liquid level detection means installed in the water tank to detect low liquid level and high liquid level, and a signal input from the liquid level detection means to invert and hold the output signal at the low liquid level of the water tank and at the same time when the water tank is high. a liquid level detection circuit that releases and holds a signal that is inverted and held at the liquid level;
a pump that operates in response to the output signal of the liquid level detection circuit to control the liquid level in the water tank; and a pump that operates in response to the output signal of the liquid level detection circuit and outputs the output signal of the liquid level detection circuit after a certain period of time. and a timer circuit that forcibly reverses the output signal and releases the self-operation before the next reversal of the output signal of the liquid level detection circuit.
