Embodiment 1

[0025] Embodiment one, combined with the attached figure 1 and Figure 5 , a pressurized hot water circulation control device, including a water pump (1) and a return water control unit, the water pump (1) is set on the water inlet pipe of the water heater (12), and the output terminal of the return water control unit is connected to the GPCT -On the electromagnetic coil of 25A AC contactor A (13), the input terminal of the GPCT-25A AC contactor A (13) is connected to a 220V power supply, and the output terminal of the GPCT-25A AC contactor A (13) is connected to the The power supply terminal of the water pump (1) is connected. The booster unit of the pressurized hot water circulation control device includes a water pressure switch A (2) and a normally open electromagnetic water valve. The water pressure switch A (2 ) is set on the water inlet pipe of the water heater (12), the input terminal of the water pressure switch A (2) is connected to a 220V power supply, and the outp...

Embodiment 2

[0030] Embodiment two, combined with figure 2 and Figure 6 , a pressurized hot water circulation control device, including a water pump (1) and a return water control unit, the water pump (1) is set on the water inlet pipe of the water heater (12), and the output terminal of the return water control unit is connected to the GPCT -On the electromagnetic coil of 25A AC contactor A (13), the input terminal of the GPCT-25A AC contactor A (13) is connected to a 220V power supply, and the output terminal of the GPCT-25A AC contactor A (13) is connected to the The power supply terminal of the water pump (1) is connected. The booster unit of the pressurized hot water circulation control device includes a water pressure switch A (2) and a normally open electromagnetic water valve. The water pressure switch A (2 ) is set on the water inlet pipe of the water heater (12), the input terminal of the water pressure switch A (2) is connected to a 220V power supply, and the output terminal ...

Embodiment 3

[0034] Embodiment three, such as image 3 and Figure 6 As shown, on the basis of the circuit with the temperature controller (18) in the above-mentioned return water control unit, a trigger delay relay (20) is added, and the output terminal of the water pressure switch A (2) is connected to the Trigger the trigger port of the delay relay (20), the power supply terminal of the trigger delay relay (20) is connected to a 220V power supply, the output terminal of the trigger delay relay (20) is connected to the power supply of the temperature controller (18) end connected.

[0035] In this way, each time the hot water tap (11) is turned on, the water pressure switch A (2) is closed after sensing the water flow, the trigger delay relay (20) is powered on, and the temperature controller (18) is powered on. Then control the operation of the water pump (1), when the temperature in the return pipe (10) reaches a certain value, the temperature controller (18) is disconnected, and the...

Abstract

The invention relates to a supercharged hot water circulation device which comprises a water pump, a water return control unit, a water pressure switch and a constantly-open type electromagnetic water valve. The water pressure switch is arranged on a water inlet pipe of a water heater, and the input end of the water pressure switch is connected with a 220 V power source. The output end of the water pressure switch is divided into two ways, wherein one way is connected with the power end of the constantly-open type electromagnetic water valve, and the other way is connected to an electromagnetic coil of an alternating-current contactor B. The input end of the alternating-current contactor B is connected with a 220 V power source, and the output end of the alternating-current contactor B is connected with a water pump power source. The water pressure switch and the electromagnetic water valve are additionally arranged, when hot water is used, the water pressure switch is turned off, the normally-open type electromagnetic water valve is closed, water flow of a water return pipe is cut off, a water pump is started to work, and the purpose of supercharging is achieved.

Description

technical field [0001] The invention relates to a hot water circulation system, in particular to a pressurized domestic hot water circulation control system. Background technique [0002] The domestic hot water circulation system has successfully solved the waste phenomenon in the process of using hot water at home, and completely bid farewell to the confusion of "turning on the cold water before turning on the faucet to have hot water". Through water pumps, temperature control systems, remote control systems, and water flow pressure control The system achieves the comfortable life of "when the faucet is turned on, hot water comes immediately". [0003] The effect of the existing hot water circulation system is that the water pump works, and the hot water circulates in the return pipe to ensure that people can use the hot water in real time. However, the current hot water circulation system does not have a pressurization function. In some cases, the pressure of the hot wate...
