Principle of the invention
Firstly, the principle of the pipeline system is as follows: the water in the hot water tank 2 is heated by the boiler 3 and then returns to the hot water tank 2 to finish the circular heating, and the hot water enters the third booster pump 9 through the hot water shower pipeline to supply hot water to the shower head 5; the cold water tank 1 supplements water for the hot water tank 2 through a water supplementing pipeline and a second booster pump 6, and cold water in the cold water tank 1 enters a first booster pump 4 through a cold water shower pipeline to supply water to the shower head 5; the water supplementing control circuit realizes automatic water supply to the cold water tank 1 and water supplementation of the hot water tank 2 through high-low liquid level control, and the water quantity of the cold water tank 1 is maintained in a certain range to meet the water demand of the whole system.
Secondly, the principle of a water replenishing control circuit is as follows: the method comprises the steps that the method is started for the first time, a button switch SB is pressed to supply power to a water supplementing control circuit, at the moment, a contactor switch KM is closed, the circuit is self-locked, for example, the water supplementing liquid level is 50% and the water stopping liquid level is 80%, if the water amount in a water tank is lower than 50%, a low liquid level floating ball switch SL and a high liquid level floating ball switch SH are kept in a normally closed state, a contactor KM is electrified, and a water supplementing execution component is controlled to supply water to the water tank; when the water amount in the water tank is lower than 50% but not higher than 80%, the low liquid level float switch SL is disconnected, the high liquid level float switch SH still keeps a normally closed state, the contactor switch KM is still in a closed state, the contactor KM is still electrified, and the control element continues to supply water to the water tank; when the water amount in the water tank is higher than 80%, the low liquid level float switch SL and the high liquid level float switch SH are disconnected, at the moment, the contactor KM loses power, and water supply is stopped;
in a specific use process, when the water level in the water tank is lower than 80%, the high liquid level float switch SH is switched to a normally closed state, when the water amount in the water tank is lower than 50%, the low liquid level float switch SL is switched to a normally closed state, the contactor KM is electrified to start water replenishing until the water amount in the water tank is higher than 80%, and therefore automatic water replenishing circulation is formed;
two sets of water replenishing control circuits can be arranged to realize the function of respectively replenishing water to the cold water tank 1 and the hot water tank 2, if the water volume of the hot water tank 2 is lower than 50%, the second booster pump 6 is started to absorb water, and water in the cold water tank 1 is pumped into the hot water tank 2 to replenish water to the hot water tank 2; if the water quantity of the cold water tank is lower than 50%, the electric valve 17 in the water inlet pipeline is opened, water can be supplied to the cold water tank 1, and therefore the requirement of one-key starting and automatic circulating water supply is met.
In addition, it should be noted that the terms "first", "second", "third", and the like in the specification are used for distinguishing various components, elements, steps, and the like in the specification, and are not used for indicating a logical relationship or a sequential relationship between the various components, elements, steps, and the like, unless otherwise specified or indicated.
