Water heater

Abstract

The invention provides a water heater which comprises a water tank, a compressor, a coiled pipe, a throttling device, a heat exchanger, an air duct, a draught fan, an electric control system, a selecting device and a controlling device; the compressor is arranged outdoors; the heat exchanger is arranged indoors, and the heat exchanger is connected with the compressor; a first air outlet of the air duct is formed indoors, and a second air outlet is formed outdoors; the draught fan is arranged indoors; the controlling device is arranged indoors and connected with the selecting device and the air duct, and the working mode of the water heater and the opening and closing of the first air outlet and the second air outlet are controlled according to a selecting signal. According to the water heater, the working mode of the water heater is selected according to a user by the controlling device, the opening and closing of the first air outlet and the second air outlet are controlled, the wasted cooling capacity is utilized effectively, in addition, due to the fact that the heat exchanger is arranged outdoors, the heat exchanger is prevented from frost formation, the defrosting process is omitted, and the energy efficiency utilization rate of the water heater is improved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a water heater. Background technique [0002] At present, the air energy heat pump hot water technology is developing rapidly by taking advantage of its advantages of energy saving, green environmental protection, safety and reliability. After heat exchange, it becomes a low-temperature and high-pressure gas, and after passing through the throttling parts, it becomes a low-temperature and low-pressure gas. After exchanging heat with the air through the evaporator, it returns to the compressor through the four-way valve, forming a heating and heating cycle. During the energy exchange process, only The purpose of heating the hot water by the heat pump is realized, which leads to the waste of the heat exchange energy of the hot water machine and reduces the energy utilization rate; in addition, in order to solve the defrosting problem of the air source heat pump water machine, th...

[0002] At present, the air energy heat pump hot water technology is developing rapidly by taking advantage of its advantages of energy saving, green environmental protection, safety and reliability. After heat exchange, it becomes a low-temperature and high-pressure gas, and after passing through the throttling parts, it becomes a low-temperature and low-pressure gas. After exchanging heat with the air through the evaporator, it returns to the compressor through the four-way valve, forming a heating and heating cycle. During the energy exchange process, only The purpose of heating the hot water by the heat pump is realized, which leads to the waste of the heat exchange energy of the hot water machine and reduces the energy utilization rate; in addition, in order to solve the defrosting problem of the air source heat pump water machine, the defrosting of the system will lead to a loss of energy efficiency. Reduced, thereby reducing the effect of heating water and reducing the demand for product use
