[0002] An air source heat pump is an energy-saving device that utilizes higher-grade energy to transfer heat from a lower-grade heat source (such as air) to a higher-grade heat source. Through heat pump technology, it converts unusable lower-grade heat energy (such as heat in the air) into usable higher-grade heat energy, thereby achieving energy savings. Air source heat pumps are widely used in heating, cooling, and hot water supply. For example, in the building industry, air source heat pumps can integrate heating, cooling, dehumidification, and hot water functions, becoming a core technology for low-carbon heating.

[0003] Publication No. CN214665406U discloses a rapid defrosting device for an air source heat pump. Multiple sets of evenly distributed, perpendicular to the base are fixedly installed on one side surface of the base. A support plate parallel to the base is slidably installed on the limit posts. A pump body is fixedly installed on the center of the support plate's surface away from the base. A heat insulation cover is fixedly connected to one side surface of the base. A heating chamber is fixedly installed on the center of the surface of the heat insulation cover away from the base. Multiple sets of evenly distributed heating wires are fixedly installed inside the heating chamber. A temperature sensor is fixedly installed on the surface of the heat insulation cover away from the base, achieving rapid defrosting of the pump body.

[0024] In this embodiment: the fan 6 and the heating component 8 work together to generate hot airflow to defrost the pump body 10. The guide channel 11 has a certain inclination, which allows water droplets to flow into the collection pipe 12. The water droplets flow into the water storage tank 15 through the collection pipe 12 for collection. The heating seat 14 can heat the water source in the water storage tank 15, thereby increasing the temperature inside the insulation cover 3 and improving the defrosting efficiency.

[0025] As a technical optimization of this utility model, the heating component 8 includes a heating chamber 801, the upper surface of which is connected to the inner top wall of the heat insulation cover 3, and multiple sets of evenly distributed electric heating rods 802 are fixedly installed inside the heating chamber 801.

[0026] In this embodiment: by activating the electric heating rod 802, the temperature inside the heating chamber 801 can be heated and hot air can be generated in conjunction with the fan 6 to defrost the pump body 10.

[0027] As a technical optimization of this utility model, a drain pipe 16 is fixedly connected to the left side of the water storage tank 15. The bottom end of the drain pipe 16 passes through the base 1 and extends to the bottom of the base 1. A second valve 17 is fixedly installed on the outer surface of the drain pipe 16. Both the first valve 13 and the second valve 17 are solenoid valves.

[0028] In this embodiment: by opening the second valve 17, the water inside the water storage tank 15 can be discharged to the outside through the drain pipe 16, and by connecting the external water source to the drain pipe 16, water can be injected into the inside of the water storage tank 15.

[0029] As a technical optimization of this utility model, a temperature sensor 9 is fixedly connected inside the heat insulation cover 3.

[0030] In this embodiment: by providing a temperature sensor 9, the temperature inside the insulation cover 3 can be monitored in real time, and the temperature data inside the insulation cover 3 can be transmitted to the control panel 2, so as to understand the changes in ambient temperature during the defrosting process in a timely manner.

[0035] The working principle and usage process of this utility model are as follows: During use, the electric heating rod 802 is first activated through the control panel 2 to heat the heating chamber 801. Then, the fan 6 delivers air to the heating chamber 801 through the air supply pipe 7, generating hot air. The hot air blows on the pump body 10, causing the frost layer on the surface of the pump body 10 to melt into water droplets. The water droplets flow into the collection pipe 12 along the guide groove 11. At this time, the first valve 13 is in the open state, and the water droplets flow into the water storage tank 15 through the collection pipe 12. Then, the heating seat 14 heats the water in the water storage tank 15, increasing the temperature inside the insulation cover 3, thereby improving the defrosting efficiency and realizing the recycling and utilization of water resources.
