Water heater and its control method

Abstract

The invention provides a water heater and a control method thereof. The water heater includes: a compressor, a four-way valve, a three-way valve, a first heat exchanger, a first fan assembly, a second fan assembly, a water tank, a second heat exchanger, a detection module, and a controller; wherein, the compressor The air outlet is connected to the first end of the four-way valve, the second end of the four-way valve is connected to one end of the first heat exchanger, and the third end of the four-way valve is connected to one end of the second heat exchanger; the first heat exchanger The other end of the heat exchanger is connected to the outer coil on the upper part of the water tank; the other end of the second heat exchanger is connected to the outer coil on the lower part of the water tank; the three-way valve is set in the pipeline between the four-way valve and the first heat exchanger Above; the controller is connected with the detection module, and is used to control the start and stop of the first / second heat exchanger, the first / second fan assembly and the three-way valve according to the outdoor ambient temperature and / or the temperature inside the water tank. Through the technical solution of the present invention, the problem of blowing cold air from the water heater is effectively improved, and better customer experience is realized.

Description

technical field [0001] The present invention relates to the technical field of water heaters, in particular to a water heater and a control method for the water heater. Background technique [0002] The application of air conditioners is becoming more and more common, and domestic air-energy water heaters are becoming more and more accepted by market customers. In the process of technology precipitation, Japanese companies are at the forefront. In conventional product design, there are different product design directions of split type and integral type, and various fan schemes of top air outlet and axial air outlet. [0003] Such as figure 1 The product shown is an integral square air energy water heater. The upper part of the product is equipped with a compressor and an evaporator for absorbing heat. The wind structure guides the cold air to the kitchen, which is used to reduce the temperature rise caused by cooking in the kitchen, so as to achieve a better customer exper...
