の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention stops the operation of the hot water pump when the hot water tap is closed, and operates the hot water pump when the hot water tap is open to forcefully send hot water in the hot water storage tank to the hot water tap. The present invention relates to an improvement of a hot water supply control device for a hot water storage type water heater.

させるようになされている。 Generally, in this type of hot water storage type water heater, the open/closed state of the hot water tap is detected by detecting changes in the state of hot water in the hot water passage from the hot water pump to the hot water tap, and when the hot water tap is open, the hot water pump is activated. Opening/closing detection means for activation is provided. For example, Kimiaki Sane
In the method disclosed in Publication No. 57-41610, a pressure switch (see reference numeral 3a in the same publication) is provided in the hot water supply passage,
When the hot water tap is opened, the pressure drop in the hot water passage causes the pressure switch to turn on, thereby operating the hot water pump.

ている。 By the way, in the above-mentioned water heater, there is usually a gap between the hot water pump and the hot water faucet in the hot water supply passage.
A check valve that allows flow from the hot water pump to the hot water faucet is interposed to prevent the hot water faucet from communicating with the hot water storage tank and being exposed to the atmosphere when the hot water faucet is closed.

すると、給湯栓を閉じたのち給湯通路内の圧力が
安定して一定になるまでの間、逆止弁前後の圧力
が微妙に変化するためと考えられる。 However, the above-mentioned conventional device has a drawback in that the check valve chatters and generates noise when the operation of the hot water pump is stopped by closing the hot water tap. The reason for this phenomenon is believed to be that the pressure before and after the check valve changes slightly after the hot water tap is closed until the pressure in the hot water passage becomes stable and constant.

防止することを目的とするものである。 Therefore, in view of this, the present invention delays the stop timing of the hot water pump when the hot water tap is closed, thereby eliminating pressure fluctuations before and after the check valve and stabilizing the differential pressure across the check valve. By continuing to operate the hot water pump until the water reaches zero, the purpose is to ensure that the check valve closes without chattering, thereby preventing the occurrence of noise caused by chattering. be.

When the hot water tap 11 is in an open state, the amount of hot water flowing through the hot water supply passage 10 is a predetermined amount (for example, 1.2/min) or more,
In addition, the pressure inside the hot water supply passage 10 is a predetermined pressure (for example, 0.45
Kg/cm 2 G) or less. Therefore, each of the flow switch 12 and pressure switch 14 is turned on.
Due to the operation and the closing of the normally open contacts MR 1-1 and MR 2-1 of the reaction relays MR 1 and MR 2 , the hot water supply pump 8 is in the operating state, and the hot water in the hot water storage tank 1 is supplied by the operation of the hot water supply pump 8. The hot water is fed under pressure from the suction passage 9 through the hot water supply passage 10 to the hot water tap 11 .

Subsequently, when the amount of hot water supplied becomes less than a predetermined amount (for example, 1.0/min), the flow switch 12 is also turned off and the hot water pump 8 attempts to stop its operation.

Normally closed contact of reaction relay MR 1 upon OFF operation
When MR 1-2 is closed, the normally closed contact MR 2-2 of the reaction relay MR 2 is closed as the flow switch 12 is turned OFF, and a closed state signal for the hot water tap 11 is output. Therefore, the timer means TM is activated, its normally open contact TM 1 is closed, and a continuous signal is output for a predetermined time T (for example, 3 seconds).
Therefore, the relay MR 3 is turned ON, its normally open contact MR 3-1 is closed, the operation continuation device 17 starts operating, and the operation of the hot water pump 8 is continued for a predetermined time T. Then, this predetermined time T
During this period, pressure fluctuations before and after the check valve 16 disappear, and the differential pressure before and after the check valve 16 becomes stable and zero. As a result, the check valve 16 is first closed by the biasing force of the built-in spring, and then is further pressed by the pressure inside the accumulator 13 to smoothly and reliably close the hot water supply passage 10. Therefore, when the hot water tap 11 is closed, the check valve 16 can be closed smoothly without chattering, making the water heater quiet and desirable.

It goes without saying that the present invention is not limited to this, and can be similarly applied to other hot water supply control devices for hot water storage type water heaters that collect solar heat to heat hot water in a hot water storage tank. .

せることができるものである。 As explained above, according to the present invention, when the hot water tap is opened, the open/close detection means operates the hot water pump to forcefully feed hot water in the hot water storage tank to the hot water tap via the hot water supply passage, and the hot water supply pump is forced to flow through the hot water supply passage into the hot water supply passage. In a hot water supply control device for a hot water storage type water heater equipped with a stop valve, when the hot water tap is closed, the operation is activated by a continuation signal output from a timer means for a predetermined period of time until pressure fluctuations before and after the check valve disappear. Since the continuation device is activated to continue the operation of the hot water pump for a predetermined period of time, the check valve can be closed smoothly without chattering when the hot water tap is closed, thereby preventing the occurrence of chattering. It is possible to prevent the occurrence of noise caused by the noise and improve quietness performance.
