Embodiment Construction

[0061] figure 1 is a schematic structural diagram of a water heater according to an embodiment of the present invention. The water heater includes a heat pump heating system 10 (shown as a dotted box in the figure) and a water storage tank 20 . The heat pump heating system 10 uses the heat of the heat pump cycle to heat water, and the water storage tank 20 is used to store the water before and / or after heating by the heat pump heating system 10 . In the embodiment of the present invention, multiple water supply modes are preset in the water heater, each water supply mode has a corresponding execution condition, and the execution condition may include threshold ranges of one or more parameters such as water supply parameters and environmental parameters. After the water heater is started, the water supply mode can be automatically selected and determined according to the user's water consumption and the environment in which the water heater is located, and the operating status...

Abstract

The invention relates to a water heater and a control method thereof. Specifically, the water heater comprises a heat pump heating system and a water storage tank. The invention further provides the control method of the water heater. The control method comprises a work process repeatedly and cyclically executed. The work process comprises the steps that water supply signals indicating that the water heater supplies water outwards one or more times are received; every time the water supply signals are received, the water supply operation of the water heater is started, water stored in the water storage tank is supplied to a water outlet pipeline of the water heater to be supplied outwards, and the amount of water supplied outwards is detected in real time; when the accumulated amount of water supplied outwards in the work process reaches the preset value, environment parameters of the environment where the water heater is located are obtained; the subsequent water supply mode of the water heater in the water supply operation is determined according to the environment parameters; and the running state of the heat pump heating system and / or the water storage tank is adjusted according to control parameters preset in the determined water supply mode, and accordingly various water utilization requirements of users under different conditions are met.

Description

technical field [0001] The invention relates to water heater technology, in particular to a water heater and a control method thereof. Background technique [0002] Hot water is a necessity in people's life. However, traditional water heaters (electric water heaters, gas water heaters) have the disadvantages of high energy consumption, high cost, and serious pollution, while solar water heaters are restricted by meteorological conditions. [0003] In view of the above problems, heat pump water heaters have appeared in the prior art, which use electric energy as power to draw heat from the low-temperature side to heat domestic water for supply to users. [0004] Heat pump water heaters can use air, water, solar energy, geothermal heat, etc. as low-temperature heat sources, among which air source heat pump water heaters have better comprehensive performance and are not restricted by the environment. The air source heat pump water heater in the prior art is mainly composed of ...
