Method 1: Adjust the output power of water pump 1 and water pump 22, and lower the flow rate of water pump 1 21 relative to the flow rate of water pump 2 22, so that the flow rate of the cold water channel of the cold and heat exchanger 4 is reduced relative to its hot water channel , that is, the flow of water flowing from the a interface of the cold heat exchanger 4 to the b interface is reduced relative to the flow of water flowing from the c interface of the cold heat exchanger 4 to the d interface, so each in the cold water channel of the cold heat exchanger 4 One unit of water can obtain more heat, so that the temperature of the water flowing out from the outlet of the cold and heat exchanger 4b rises compared to when the water pump is not adjusted. The water temperature in the hot tank 5 can rise, realizing the purpose of regulating the water temperature in the hot tank 5 to keep it stable.

Method 2: Adjust the mixing ratio of the water mixing valve 7 to increase the water flow ratio of the two interfaces b:a, then the flow rate of the hot water channel of the cold and heat exchanger 4 will increase, that is, from the flow of the cold and heat exchanger 4 The flow of water flowing from the c interface to the d interface will increase, thereby bringing more heat, making the temperature of the water in the cold water channel of the cold heat exchanger 4 rise, that is, the water flowing from the a interface of the cold heat exchanger 4 to the b interface The temperature of the water rises, so that the temperature of the water flowing out from the outlet of the cold heat exchanger 4b rises compared to when the water mixing valve 7 is not adjusted, and when the heat preservation temperature set by the hot tank 5 remains unchanged, it flows into the hot tank The water temperature in the 5 can rise, and the purpose of regulating the water temperature in the hot tank 5 to keep it stable has been realized. The limit case of method two is to adjust the water flow ratio of the two interfaces b:a of the mixing valve 7 to the maximum, so that the temperature of the cold water coming out from the a interface to the b interface of the cold and heat exchanger 4 is the highest, and the heat tank 5 is set Under the constant situation of fixed heat preservation temperature, the temperature in the hot tank 5 can be made to increase.

Method 3: On the one hand, adjust the output power of water pump 1 21 and water pump 2 22, and lower the flow rate of water pump 1 21 relative to the flow rate of water pump 2 22; on the other hand, adjust the mixing ratio of water mixing valve 7 so that the two The water flow ratio of the two interfaces b:a increases, and this method combines method one and method two at the same time, so that the temperature of the water flowing into the hot tank 5 increases.

Situation 2: When the user uses water, the water temperature in the hot tank 5 is higher than the set temperature:

In case two, the three methods in case one can be reversed, namely:

Method 4: Adjust the output power of water pump 1 and water pump 22, and increase the flow rate of water pump 1 21 relative to the flow rate of water pump 2 22, then the flow rate of the cold water channel of the cold and heat exchanger 4 will increase relative to its hot water channel , that is, the flow of water flowing from the a interface of the cold heat exchanger 4 to the b interface increases with respect to the flow of water flowing from the c interface of the cold heat exchanger 4 to the d interface, so each in the cold water channel of the cold heat exchanger 4 The amount of heat obtained by one unit of water will become less, so that the temperature of the water flowing out from the outlet of the cold heat exchanger 4b is lower than that when the water pump is not adjusted. The water temperature in the hot tank 5 can be reduced, and the purpose of regulating the water temperature in the hot tank 5 to keep it stable has been realized.

Method 5: Adjust the mixing ratio of the water mixing valve 7 to reduce the water flow ratio of the two interfaces b:a, then the flow rate of the hot water channel of the cold and heat exchanger 4 will decrease, that is, from the c of the cold and heat exchanger 4 The flow of water flowing from the interface to the d interface will decrease, and the heat brought by the hot water channel will decrease, so that the water temperature in the cold water channel of the cold heat exchanger 4 will decrease, that is, the water flowing from the a interface of the cold heat exchanger 4 to the b interface The temperature of the water is reduced, so that the temperature of the water flowing out from the outlet of the cold heat exchanger 4b is lower than that when the water mixing valve 7 is not adjusted. The water temperature in the tank can be reduced, and the water temperature in the hot tank 5 is adjusted to keep it stable. The limit case of method five is to adjust the water flow ratio of the two ports b:a of the mixing valve 7 to 0, that is, the b port is completely closed, so that there is no water flowing through the hot water channel of the cold heat exchanger 4, and the cooling and heat exchange The water temperature that comes out from the a interface of the device 4 to the b interface is the lowest, and the temperature in the hot tank 5 can be reduced under the constant situation of the heat preservation temperature set by the hot tank 5 .

Method 6: On the one hand, adjust the output power of water pump 1 21 and water pump 2 22, and increase the flow rate of water pump 1 21 relative to the flow rate of water pump 2 22; on the other hand, adjust the mixing ratio of water mixing valve 7 so that the two The ratio of the water flow of two interfaces b:a is reduced, and this method combines method 4 and method 5 at the same time, so that the temperature of the water flowing into the hot tank 5 is reduced.

Situation 3: When using water, users need to use warm boiled water at a lower temperature:

Method 7: Adjust the output power of water pump one 21 and water pump two 22, and increase the flow rate of water pump one 21 relative to the flow rate of water pump two 22, then the flow rate of the cold water channel of the cold heat exchanger 4 is relative to the flow rate of its hot water channel increase, that is, the flow of water flowing from interface a to interface b of the cold and heat exchanger 4 is increased compared to the flow of water flowing from interface c to interface d of the cold and heat exchanger 4, so that more water can be taken away heat, so that the temperature of the water flowing out from the d interface of the cold and heat exchanger 4 decreases, and then the water temperature flowing into the b interface of the mixing valve 7 will be lower, so that the temperature of the mixed water flowing out of the c outlet of the mixing valve 7 reduce.

Method 8: While increasing the flow rate of water pump 1 21 relative to the flow rate of water pump 2 22, adjust the mixing ratio of water mixing valve 7 to increase the flow ratio of b:a. In addition to the effect of reducing the outlet water temperature, it can further increase the flow rate of low-temperature water flowing into the interface of the mixing valve 7 b and reduce the flow rate of high-temperature water flowing into the interface a of the mixing valve 7. The water temperature of the water flowing out of the interface is further reduced; in the eighth method, on the one hand, the flow of the water pump one 21 is increased relative to the flow of the water pump two 22, so that the water temperature of the water flowing out of the b interface of the cold and heat exchanger 4 can be reduced. Therefore there is the effect of reducing the temperature of the water flowing into the heat tank 5, on the other hand, improving the water flow ratio of the two ports b of the mixing valve 7: a can make the temperature of the water flowing out from the b port of the cold heat exchanger 4 Therefore, there is an effect of increasing the temperature of the water flowing into the hot tank 5, and the two effects are opposite, so when the method is properly adjusted, a balance can be reached, that is, the temperature of the water flowing into the hot tank 5 is constant, and at the same time Reduce the temperature of the water that the user draws.

Implementation principle of the present invention and beneficial effect are:

When the ports a and b of the three-way solenoid valve 131 are opened and the port c is closed, only warm boiled water flows from the port c of the water mixing valve 7 at the water vapor separation box 9, and the water from the port c of the water mixing valve 7 flows out. The temperature of the water is adjustable, and no matter what the temperature is, it is completely boiled cooked water, which solves the problem of easy breeding of bacteria in the pipeline, and the water intake is instant and efficient;

And when the a, c interfaces of the three-way electromagnetic valve-31 are opened and the b-interface is closed, the water pump-21 can send the water in the water supply device 1 into the water-steam separation box 9 through the a, c interfaces of the three-way electromagnetic valve-31 successively Inside, since the b interface of the three-way solenoid valve 131 is closed, the water vapor separation box 9 only has room temperature water flowing from the water supply device 1, and the user can directly take unboiled room temperature water according to needs;

In addition, by using the above-mentioned heat exchange control method to control the water temperature, the stability of the water temperature in the hot tank 5 can be ensured, thereby ensuring that the flow rate of the user is larger and more stable when taking water, and it is also possible for the user to take boiled water at a lower temperature. .

In summary, the present invention can quickly provide users with drinking water at any temperature from normal temperature water to boiling water, and solves the problem of long waiting time for users to get water.

The above is only an embodiment of the present invention, and is not intended to limit the present invention. Various modifications and variations of the present invention will occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
