Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. . Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

Example

As shown in Figure 1, it is an embodiment corresponding to the technical solution of the present utility model, including a temperature control switch 1, a three-position two-way solenoid valve A connected to a water storage tank 5, and a water level sensor 6 is included in the water storage tank 5 to detect the water level. The height delays the service life of the miniature water pump 7, and the water storage tank 5 is connected to the miniature water pump 7, the three-position two-way solenoid valve B, and the water mixing valve 4 in sequence, wherein the temperature sensor 3 is included in the water mixing valve 4 to detect whether the temperature reaches The set temperature, temperature control switch 1, three-position two-way solenoid valves A and B, water storage tank 5, water level sensor 6, micro water pump 7, and temperature sensor 3 are all connected to the single-chip microcomputer control panel, which solves the problem of hot and cold water heater temperature problems, while also avoiding the waste of water resources.

Improvements of the utility model:

(1) The water storage tank is installed to reduce the number of times of use of the water pump and prolong the use time of the water pump.

(2) When the temperature is higher than the set temperature, start the micro water pump to draw the water in the water storage tank to mix with the hot water in the water mixing valve, and use the temperature sensor to detect the temperature until it drops to the set temperature.

(3) When the water level of the water storage tank is higher than the target water level or exceeds the set time, the micro water pump will be started to draw it into the toilet.

The working principle of the utility model is as follows:

When the water heater is turned on for showering, the temperature control switch 1 detects the temperature of the output hot water, transmits the data back to the single-chip controller, and compares it with the set temperature. If the temperature does not reach the set temperature, turn off the three Two-way solenoid valve A makes it flow into the water storage tank 5 for storage. When the temperature reaches the set value, hot water is output. However, since the gas water heater is an instant water heater, the output cannot be guaranteed. The temperature of the hot water is kept at a constant temperature. When the temperature of the hot water is higher than the set temperature, the three-position two-way solenoid valve A is opened to flow the hot water into the water mixing valve 4. At the same time, the micro-water pump 7 is started, and the three-position two-way solenoid valve B is opened. The water in the water storage tank 5 is drawn into the mixing valve 4 to mix with the hot water therein, and the mixing valve 4 contains a temperature sensor 3, which is output for bathing when the temperature drops to a set temperature.
