Embodiment 1

[0028] Such as figure 1 As shown, a circulating heat pump water heater control device is mainly used in commercial machines, including a heat pump device and a water tank 4, wherein the heat pump device is used to heat or keep warm the water in the water tank 4.

[0029] In this embodiment, a tap water inlet pipe 3, a controller (not shown in the figure), a relay 1, and a replenishment solenoid valve 2 are also provided.

[0030] The tap water inlet pipe 3 is connected to the water heater tank 4, and the water replenishment solenoid valve 2 is arranged on the tap water inlet pipe 3. One end of the control end of the water replenishment solenoid valve 2 is connected to the relay 1, and the other end is connected to the zero line through the water tank float level switch 5 to control The controller is connected with the control terminal of the relay 1, and the temperature sensor of the water heater tank 4 is connected with the controller. Water tank float water level switch 5 i...

Embodiment 2

[0042] Such as figure 2 As shown, in this embodiment, the heat pump device includes a compressor, a condenser 6, a throttle valve and an evaporator connected in series in sequence, wherein the condenser 6 is connected to the water tank 4 through a circulation loop, and the circulation loop includes water flowing through the condenser 6 to the water supply branch 7 that flows to the water tank 4 and the return water branch 8 that the water flows from the water tank 4 to the condenser 6 .

[0043] A first filter 9, a circulating water pump 10 and a first one-way valve 11 are sequentially arranged on the backwater branch 7 along the flow direction of the water flow. Along the flow direction of the water flow, the water supplement solenoid valve 2, the second filter 12 and the second one-way valve 13 described in the first embodiment are sequentially arranged.

[0044] In this embodiment, the tap water inlet pipe 3 is connected to the unidirectional flow return water branch 8, s...

Abstract

The invention relates to a circulating heat pump water heater control device and method. The circulating heat pump water heater control device comprises a tap water inlet pipe, a controller and a relay. The tap water inlet pipe is in communication with a water heater water tank, and a water supplementing electromagnetic valve is arranged on the tap water inlet pipe. One end, namely the control end, of the water supplementing electromagnetic valve is connected with the relay, and the other end of the water supply electromagnetic valve is connected with a zero line through a water tank floatingball water level switch. The controller is connected with the control end of the relay, and a temperature sensor of the water heater water tank is connected with the controller. The intelligent watersupplementing and heating can be achieved by the control over the water supply electromagnetic valve and the relay; and by the simple logic control, the problem that a circulating heat pump water heater cannot keep the water temperature of the user side constant is solved, and better experience is provided for using water of users.

Description

technical field [0001] The invention relates to a control method, in particular to a control device and method for a circulating heat pump water heater. Background technique [0002] The water replenishment scheme of the existing commercial circulating heat pump water heater generally adopts manual water replenishment, which cannot be intelligently controlled, which will cause inconvenience to customers. In addition, manual water level replenishment cannot guarantee the water temperature of the water tank, resulting in unstable water temperature on the user side. Contents of the invention [0003] The main purpose of the present invention is to provide a control device for a circulating heat pump water heater with stable outlet water temperature in order to solve the technical problems in the prior art. [0004] The invention also provides a control method for the circulating heat pump water heater. [0005] For realizing the above object, technical scheme of the present...
