Description
Technical Field
The invention relates to the technical field of defrosting devices of air conditioner outdoor units, in particular to defrosting equipment and a defrosting method of an air conditioner outdoor unit.
Background
When the air conditioner is in a heating mode, the heat exchanger of the outdoor unit is in a heat absorption state, so that moisture and dust in the surrounding air can be condensed on coils of the heat exchanger together, and heat exchange gaps among the coils are blocked. If the air conditioner is not cleaned in time, the problem of insufficient heat exchange amount of the outdoor unit can occur, and the normal operation of the air conditioner is affected until the compressor is down. Specifically, the compressor of the outdoor unit compresses the refrigerant, the compressed high-temperature gaseous refrigerant flows into the indoor unit, heat is released to supply hot air for a user, meanwhile, the refrigerant becomes low-temperature liquid state after condensation and liquefaction, the low-temperature liquid state refrigerant flows into the outdoor unit from the indoor unit, and heat is absorbed from the outdoor environment in the heat exchanger of the outdoor unit in an evaporation and heat absorption mode, so that the temperature of the heat exchanger and the surrounding environment is reduced. The temperature of the outer surface of the heat exchanger is usually below 0 ℃, when the humidity of the external environment is high, frosting phenomenon is often generated, and the heating effect of the air conditioning system is further affected, so that the heat exchanger of the outdoor unit is required to be defrosted.
In the existing reverse circulation defrosting technology, the heating process is required to be temporarily interrupted, and heat is transmitted to the outdoor unit in a way of reversing the high-temperature refrigerant, so that the heat exchanger of the outdoor unit absorbs the heat quantization frost. In the defrosting process through reverse circulation, the high-temperature refrigerant reversely flows to the heat exchanger of the outdoor unit, so that the heat transferred to the indoor unit by the air conditioning system is lost, the heating capacity of the heat pump system is reduced until the indoor temperature is reduced, and the comfort of a user is affected.
By searching, the prior patent (publication number: CN 219036894U) discloses a defrosting assembly and an air conditioner outdoor unit. The defrosting assembly comprises a driving mechanism, a driven mechanism and a first brush rod. The drive mechanism is configured to output a vertical reciprocating motion.

The driven gear and the first brush rod are driven by the driving mechanism to reciprocate in the vertical direction, and the driven gear is meshed with the fixed rack on the case of the air conditioner outdoor unit, so that the driven gear moves up and down and drives the first brush rod to rotate, and the bristles or the felt on the rotating first brush rod clean sundries such as frost, dust and the like on the heat exchanger contacted with the bristles or the felt, thereby maintaining the heat exchange performance of the air conditioner and ensuring the normal operation of the air conditioner.
However, in the above scheme, there is still a certain disadvantage that the first brush rod 210 and the second brush rod 220 are vertically distributed, and the driving motor 110 and the driving screw 120 are disposed on one side of the first brush rod 210 far away from the second brush rod 220, and the driving motor 110 and the driving screw 120 drive the first brush rod 210 to move up and down, and then the first brush rod 210 drives the second brush rod 220 to move up and down, so that the overall span is larger, and the stability is slightly insufficient; for cold winter, when the heat exchanger frosts, the defrosting efficiency is low only by removing the friction between the first brush bar 210 and the second brush bar 220, so that the user comfort is affected; after the compressor in the outdoor unit works for a long time, the compressor can generate a large amount of heat, and the performance of the compressor can be affected due to untimely emission.

When the compressor 3 works, a large amount of heat can be generated by the compressor 3, the compressor 3 is overheated and is not beneficial to the normal work of the compressor 3, the coiled pipe 4 wound on the outer wall of the compressor 3 is attached to conduct and absorb the heat of the outer wall of the compressor 3, at the moment, the induced draft fan 5 is started, the induced draft fan 5 absorbs the heat collected in the coiled pipe 4 through the air inlet pipe 51 and discharges the absorbed heat into the air conveying pipe 2 through the air conveying pipe 52, the heat is conveyed to the first hollow rotating rod 873 and the second hollow rotating rod 882 through the air conveying pipe 2, the heat inside the first hollow rotating rod 873 and the second hollow rotating rod 882 can be discharged through the through holes formed in the outer walls of the first hollow rotating rod 873 and the second hollow rotating rod 882, so that the frost on the outer wall of the heat exchanger 7 can be cleaned by utilizing the bristles and simultaneously carrying out hot air blowing on the outer wall of the heat exchanger 7, and the frost cleaning efficiency is greatly improved. When the first cleaning part 87 moves to the lower side, the air conveying pipe 2 is wound on the outer wall of the I-shaped roller 65, the coil spring 61 is in a loosening state, when the first cleaning part 87 starts to move upwards, the air conveying pipe 2 can be pulled to drive the I-shaped roller 65 to rotate, the length of the air conveying pipe 2 can be released, at the moment, the rotating I-shaped roller 65 tightens the coil spring 61, and when the first cleaning part 87 moves downwards, the good elastic performance of the coil spring 61 is utilized, the I-shaped roller 65 is driven to automatically rotate through the shaft lever 63, and the air conveying pipe 2 is wound.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
