When the device is shut down to clean the frost, the device is started to inject water into the water inlet pipe, and then the water inlet pipe directs the water flow to the inside of the connecting pipe, and the connecting pipe is diverted into the inside of the shunt pipe, and then the shunt pipe sprays water on the surface of the copper plate to rinse and clean the frost on the surface of the copper plate. By setting up a cleaning device, the frost on the copper plate is effectively cleaned, which plays a role in cleaning the frost and impurities on the surface of the copper plate, reduces the risk of the surface of the copper plate cooling down quickly when the device is in use, and easily absorbs water mist in the air on the surface of the copper plate to condense into frost, blocking the copper plate, and making it difficult to circulate air, thereby improving the practicability of the device.

[0015] 2. In the utility model, by arranging a heating device, after the equipment is sprayed with water for cleaning, the user starts the heating block, and then the heating block runs to drive the heat pipe for heating. The temperature of the heat pipe is increased to heat and evaporate the water droplets on the surface of the copper plate for cleaning. By arranging a heating device, the surface of the copper plate is effectively heated, which plays a role in cleaning the residual water droplets on the surface of the copper plate, reducing the risk of residual water droplets on the surface of the copper plate after cleaning. If the water droplets are not cleaned thoroughly before use, the water droplets are likely to quickly turn into ice and condense on the surface of the copper plate, causing the gaps in the copper plate to be blocked and air flow to be difficult to circulate, thereby improving the practicability of the equipment.

The limit block 65 is fixedly connected to the inner side of the first connecting plate 1, and the connecting pipe 61 is arranged at the upper end of the copper plate 3. The upper end of the connecting pipe 61 is fixedly connected with the water inlet pipe 63, and the lower end of the connecting pipe 61 is provided with a diversion pipe 62. The surface of the connecting pipe 61 is fixedly connected with a retaining ring 64. The connecting pipe 61 is clamped with the inside of the limit block 65, and the retaining ring 64 is in contact with the surface of the limit block 65. The inside of the limit block 65 is fixedly connected with a slide rod 610.

[0025] Specifically, the inner wall of the limiting block 65 is slidably connected with a push rod 66 , and the push rod 66 is slidably connected to the surface of the sliding rod 610 .

[0026] In this embodiment: by setting the sliding rod 610, the push rod 66 can be limited, which reduces the possibility of the push rod 66 shaking when the device is in use, and easily causes the push rod 66 to separate from the surface of the push ring 64, making it difficult to limit the connecting pipe 61.

[0027] Specifically, the surface of the slide rod 610 is sleeved with a spring 69, and the two ends of the spring 69 are respectively fixedly connected to the surface of the push rod 66 and the inside of the limit block 65.

[0033] Working principle: When the device is in use, the user installs the device inside the air-conditioning outdoor unit, and then passes the refrigerant through the copper tube 5 for fluid flow. The condensed liquid vaporizes and absorbs heat, and absorbs heat and cools the gas passing through the inside of the copper plate 3. When the device is shut down to clean the frost, start the device to inject water into the water inlet pipe 63, and then the water inlet pipe 63 directs the water flow to the inside of the connecting pipe 61, and the connecting pipe 61 is diverted into the inside of the diverter pipe 62, and then the diverter pipe 62 sprays water on the surface of the copper plate 3 to rinse and clean the frost on the surface of the copper plate 3.

If the water droplets are not cleaned thoroughly before use, the water droplets are likely to quickly turn into ice and condense on the surface of the copper plate 3, causing the gaps in the copper plate 3 to be blocked and air flow to be difficult to circulate, thereby improving the practicability of the equipment.
