when the evaporator works for a long time, certain frost is formed on the surface of the inner sleeve 322 under the action of the refrigerant, the frost formed by the refrigerant can be thickened to form ice after multiple cycles, at the moment, the electromagnetic valve 16 is opened, the high-temperature and high-pressure refrigerant generated by the compressor 14 is conveyed into the conveying hole 323 by using the input pipe 35 to melt the frost formed on the surface of the inner sleeve 322, the water formed by melting can drip to the bottom of the evaporator main body 31 through the air inlet notch 324 and is discharged out through the water outlet pipe 37, and the exchanged refrigerant flows into the inner sleeve 322 for recycling under the action of the connecting disc 33 and the conveying pipe 34;
need overhaul the clearance operation to the inside heat exchange assemblies 6 of air supply heat pump water heater main part 2 through long-time work, utilize fixing bolt 632 to open first ring flange 631 and fixing bolt 632 split this moment, thereby take out heat exchange assemblies 6 whole effect that utilizes sliding block 65 and sliding tray 5, take down the stop cock on the access panel 66 again can clear up with the heat exchange tube 62 to heat exchanger main part 61 inside, utilize first ring flange 631 and fixing bolt 632 to install heat exchange assemblies 6 again after the clearance is accomplished can.
While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention and should not be taken as limiting the scope of the invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
