Description

Technical Field

[0001] The utility model belongs to the technical field of air energy water heaters, in particular to an air energy water heater device. Background Art

[0002] Air energy water heater, also known as "air source heat pump water heater", has a working principle very similar to that of air conditioner. It uses a small amount of electricity to drive the compressor. The high-pressure liquid working fluid evaporates into gas in the evaporator after passing through the expansion valve, and absorbs a large amount of heat energy from the air; the gaseous working fluid is compressed by the compressor into a high-temperature, high-pressure liquid, and then enters the condenser to release heat and heat the water... This continuous cycle of heating can heat the water to 50℃~65℃.

[0003] The air energy water heater in the prior art has certain limitations on the outdoor temperature during use. If the outdoor temperature is low, it cannot perform air energy heating. In order to solve the above problem, an air energy water heater is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an air energy water heating device in order to solve the above problems.

[0005] The technical solution adopted by the utility model is as follows: an air energy water heating device, comprising:

[0006] The outdoor unit has an auxiliary heating compartment and an equipment compartment arranged therein from top to bottom, a compressor, a liquid storage tank and an expansion valve are fixedly installed inside the equipment compartment, an evaporator is fixedly installed on both the front and rear sides of the auxiliary heating compartment, a circulating liquid outlet pipe is fixedly installed on the output end of the compressor, a circulating liquid return pipe is fixedly connected to the input end of the liquid storage tank, the output end of the liquid storage tank is fixedly connected to the input end of the expansion valve through a water pipe, the output end of the expansion valve is fixedly connected to the input end of the evaporator through a water pipe, the output end of the evaporator is fixedly connected to the input end of the compressor through a water pipe, a plurality of concave lenses are fixedly installed on the top of the outdoor unit, and a reflector is fixedly installed on the outer wall of the evaporator;

[0007] The water tank has a heat exchange tube fixedly installed inside, and both ends of the heat exchange tube are fixedly connected to the circulating liquid outlet pipe and the circulating liquid return pipe respectively.

[0008] Through the above technical scheme, the compressor compresses the refrigerant to turn it into high-temperature and high-pressure gas, and the high-temperature gas enters the heat exchange tube through the circulating liquid outlet pipe, thereby heating the water in the water tank. The high-temperature and high-pressure gaseous refrigerant that has passed the heat exchange in the water tank becomes medium-temperature and high-pressure liquid refrigerant and enters the liquid storage tank through the circulating liquid return pipe. The liquid refrigerant in the liquid storage tank passes through the expansion valve to become low-temperature and low-pressure wet steam, and the wet steam enters the evaporator again. The evaporator absorbs heat from the external air and turns the wet steam back into low-temperature gaseous refrigerant and re-enters the compressor. The above operation is repeated to continuously heat the water tank. When encountering cold weather, the external sunlight is scattered by the concave lens, and the scattered sunlight is continuously emitted by the reflector, so that the sunlight is gathered inside the auxiliary heating chamber to heat the external air, so that the air energy water heater can be used in a low-temperature environment.

[0009] In a preferred embodiment, a fan is fixedly installed on the top of the outdoor unit.

[0010] Through the above technical solution, the outside air is sucked into the auxiliary heating chamber through the fan.

[0011] In a preferred embodiment, a heat exchange chamber is fixedly installed at the bottom of the auxiliary heating chamber, a water pump is fixedly installed on the top of the water tank, the input end of the water pump is fixedly connected to the top of the water tank through a water pipe, and the output end of the water pump is fixedly connected to the outer wall of the heat exchange chamber through a water pipe.

[0012] Through the above technical solution, when the water in the water tank is heated, a part of the hot water is sucked into the heat exchange chamber through the water pump, and the external air is heated by the heat exchange chamber. The cooled water after heat exchange is pumped back into the water tank by the water pump.

[0013] In a preferred embodiment, a heat conducting sheet is fixedly installed on the top of the heat exchange chamber.

[0014] Through the above technical solution, the heat exchange efficiency is improved by providing a heat conducting sheet.

[0015] In a preferred embodiment, protective nets are fixedly installed on the outer walls of both the front and rear sides of the auxiliary heating chamber.

[0016] Through the above technical solution, a protective net is provided to prevent external impurities from entering the interior of the device.

[0017] In a preferred embodiment, the reflective plate is arranged as an inclined surface.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are as follows: the utility model provides an air-energy water heating device.

[0019] 1. When encountering cold weather, the external sunlight is scattered by the concave lens, and the scattered sunlight is continuously emitted by the reflector, so that the sunlight is gathered inside the auxiliary heating chamber to heat the external air, so that the air-energy water heater can be used in a low temperature environment.

A circulating liquid outlet pipe 107 is fixedly installed at the output end of the compressor 103, and a circulating liquid return pipe 108 is fixedly connected to the input end of the liquid storage tank 104. The output end of the liquid storage tank 104 is fixedly connected to the input end of the expansion valve 105 through a water pipe, and the output end of the expansion valve 105 is fixedly connected to the input end of the evaporator 106 through a water pipe. The output end of the evaporator 106 is fixedly connected to the input end of the compressor 103 through a water pipe. The water tank 2 has a heat exchange tube 201 fixedly installed inside it, and both ends of the heat exchange tube 201 are respectively connected to the circulating liquid outlet The pipe 107 and the circulating liquid return pipe 108 are fixedly connected. The compressor 103 works to compress the refrigerant to turn it into high-temperature and high-pressure gas. The high-temperature gas enters the heat exchange pipe 201 through the circulating liquid outlet pipe 107, thereby heating the water in the water tank 2. The high-temperature and high-pressure gaseous refrigerant after heat exchange in the water tank 2 becomes a medium-temperature and high-pressure liquid refrigerant and enters the liquid storage tank 104 through the circulating liquid return pipe 108. The liquid refrigerant in the liquid storage tank 104 passes through the expansion valve 105 to become low-temperature and low-pressure wet steam. The wet steam then enters the evaporator 106. The evaporator 106 absorbs heat from the external air to turn the wet steam back into a low-temperature gaseous refrigerant and re-enters the compressor 103. The above operation is repeated to continuously heat the water tank 2.

[0032] A plurality of concave lenses 110 are fixedly mounted on the top of the outdoor unit 1, and a reflector 109 is fixedly mounted on the outer wall of the evaporator 106. The reflector 109 is set as an inclined surface. When encountering cold weather, the external sunlight is scattered by the concave lenses 110, and the scattered sunlight is continuously emitted by the reflector 109, so that the sunlight is gathered inside the auxiliary heating chamber 101 to heat the external air, so that the air-energy water heater can be used in a low-temperature environment.

[0033] A heat exchange bin 112 is fixedly installed at the bottom of the auxiliary heating bin 101, and a heat conductive plate 113 is fixedly installed on the top of the heat exchange bin 112.

The input end of the water pump 202 is fixedly connected to the top of the water tank 2 through a water pipe, and the output end of the water pump 202 is fixedly connected to the outer wall of the heat exchange bin 112 through a water pipe.

The cooling after heat exchange is pumped back into the water tank 2 by the water pump 202.

[0034] Working principle:

[0035] The compressor 103 works to compress the refrigerant to turn it into a high-temperature and high-pressure gas. The high-temperature gas enters the heat exchange tube 201 through the circulating liquid outlet pipe 107, thereby heating the water in the water tank 2. The high-temperature and high-pressure gaseous refrigerant that has undergone heat exchange in the water tank 2 becomes a medium-temperature and high-pressure liquid refrigerant, which enters the liquid storage tank 104 through the circulating liquid return pipe 108. The liquid refrigerant in the liquid storage tank 104 passes through the expansion valve 105 to become low-temperature and low-pressure wet steam, which then enters the evaporator 106. The evaporator 106 absorbs heat from the external air to turn the wet steam back into a low-temperature gaseous refrigerant, which then re-enters the compressor 103. The above operation is repeated to continuously heat the water tank 2. When encountering cold weather, the external sunlight is scattered by the concave lens 110, and the scattered sunlight is continuously emitted by the reflector 109, so that the sunlight is gathered inside the auxiliary heating chamber 101 to heat the external air, thereby allowing the air-energy water heater to be used in a low-temperature environment.
