[0002] At present, the existing water heaters deal with the frosting problem by means of reverse cycle defrosting, hot gas bypass defrosting, and energy storage defrosting. Currently, the existing control scheme only uses one of the methods to complete the defrosting. When the water temperature is high, if the reverse cycle defrosting method is adopted, this defrosting method will have a large impact on the system and cause a large heat loss; when the water temperature of the water tank is low, if the hot gas bypass defrosting method is used alone to complete the defrosting process, it will make the hot water machine return to the hot water running state for a long time, reducing the comfort of the user

Abstract
The present invention provides a water heater and a control method thereof, wherein the water heater includes: a water tank, a compressor, a four-way valve, a coil pipe, a throttling device, a heat exchanger, a solenoid valve, a one-way valve, a first A temperature sensor, a second temperature sensor, a third temperature sensor, a detection device and a controller; the controller is respectively connected with the solenoid valve, the four-way valve, the first temperature sensor, the second temperature sensor, the third temperature sensor and the detection device, and controls The controller controls the opening or closing of the solenoid valve or the switching of the four-way valve according to the exhaust temperature, ambient temperature, heat exchanger temperature and compressor running time. The hot water machine provided by the present invention adds a solenoid valve. When the controller controls the solenoid valve to open, the four-way valve does not change direction, and performs thermal bypass defrosting; Circular defrosting, realizes two defrosting modes, reduces heat loss, makes the hot water machine defrost more efficiently, and improves the comfort of the product.
Description
Technical field [0001] The invention relates to the field of household appliances, and in particular to a water heater and a control method for the water heater. Background technique [0002] At present, the existing water heaters deal with the frosting problem in reverse cycle defrosting, hot gas bypass defrosting, energy storage defrosting, etc. The current control scheme only uses one of these methods to complete defrosting. When the water temperature is high, if the reverse cycle defrosting method is used, this defrosting method will have a large impact on the system and large heat loss; when the water tank temperature is low, at this time, if the hot air bypass defrosting method is used to complete the defrosting The process will make the hot water machine return to the hot water running state for a longer time and reduce the user's comfort. Summary of the invention [0003] In order to solve at least one of the above technical problems, an object of the present invention is...
