In the embodiment of the present disclosure, the driving device 300 is configured to drive the air to flow, the driving device 300 may be a fan disposed in the air supply duct 200, or a pump disposed on the air supply duct 200, as long as the driving device 300 can drive the air to flow, and the air with heat in the compressor installation space is conveyed to the outdoor heat exchanger installation space, which is not specifically limited.
Optionally, the number of the air outlets 130 of the heat dissipation plate 100 is multiple, and the multiple air outlets 130 are disposed at intervals on the heat dissipation plate 100.
The heat dissipating plate 100 has a plurality of outlet holes 130, and the outlet holes 130 are spaced apart from each other. Thus, the air outlet range of the heat dissipation plate 100 can be effectively expanded, and the defrosting efficiency can be improved.

By providing two heat dissipation plates 100, the air outlet range of the heat dissipation plate 100 is further expanded, and the defrosting effect is further improved. When two heat dissipation plates 100 are provided, a first air supply branch 220 and a second air supply branch 230 are provided at a second nozzle of the air supply duct 200, the first air supply branch 220 is communicated with the first heat dissipation plate 110, and the second air supply branch 230 is communicated with the second heat dissipation plate 120. By arranging the two air supply branches to supply air to the two heat dissipation plates 100 respectively, the air supply efficiency can be effectively improved.

Optionally, the air outlet directions of the air outlet holes 130 of the first heat dissipation plate 110 and the second heat dissipation plate 120 are set to be away from each other. For example, the first heat dissipating plate 110 and the second heat dissipating plate 120 are disposed in the middle of the outdoor heat exchanger 700, and the air outlet holes are disposed in a deviating manner, so as to supply air to both sides of the outdoor heat exchanger 700, and then the air with heat is blown to the outdoor heat exchanger 700 by the outdoor fan, so that the air supply is uniform, and the air supply effect can be improved.
Optionally, the number of the heat dissipation plates 100 is multiple, a second pipe orifice of the air supply pipe orifice is correspondingly provided with a plurality of air supply branch circuits, and the plurality of air supply branch circuits are respectively communicated with the plurality of air supply branch circuits in a one-to-one correspondence manner.
Like this, the user can be according to actual demand, perhaps size etc. of outdoor heat exchanger 700, installs different quantity's heating panel 100, and the air supply mouth of pipe corresponds sets up a plurality of air supply branches, communicates heating panel 100 respectively. Thus, the user can flexibly set the number of the heat dissipation plates 100 and the number of the air supply branches, and the defrosting effect can be effectively guaranteed.
Alternatively, the supply duct 200 is provided in the compressor installation space adjacent to the duct tray of the first nozzle.
The compressor generates heat during operation, and the temperature of the air in the space where the compressor is installed increases, and the temperature of the wall of the supply duct 200 near the first nozzle increases accordingly. Thus, the air supply duct 200 located in the compressor installation space can further heat the air flowing through the air supply duct 200, and the defrosting speed can be increased.
And the duct for the supply duct 200 close to the first mouth is coiled in the compressor installation space, i.e. in the form of a coil of serpentine duct. With such an arrangement, the area of the air supply duct 200 in the compressor installation space, that is, the heat exchange area of the air supply duct 200 is increased. In this way, the driving unit 300 drives the air with heat in the compressor installation space into the air supply duct 200, and the serpentine duct in the compressor installation space further heats the air flowing therethrough, so that the temperature of the air blown out from the air outlet 130 of the heat dissipation plate 100 is increased, thereby improving the defrosting efficiency.
Optionally, the supply duct 200 is of a metallic material.
The heat conductivity of the metal material is greater than that of the non-metal material, and the air supply duct 200 is made of the metal material, so that the temperature rise process of the air supply duct 200 located in the compressor installation space can be shortened, and the defrosting efficiency can be improved.
Optionally, a filter 210 is further included, and is disposed at the first nozzle of the air supply duct 200, and is used for filtering the air entering the air supply duct 200.
When the outdoor unit of the air conditioner is in an outdoor environment and air is driven by the driving unit 300 to flow, outdoor impurities, such as dust, flying insects, paper dust, etc., are inevitably sucked into the air supply duct 200. Dust is sucked in the air supply pipeline 200 and can be attached to the inner wall of the pipeline or the inner wall of the heat dissipation plate 100, so that the auxiliary defrosting device or the outdoor heat dissipater is not easy to clean, and after the air supply pipeline 200 or the heat dissipation plate 100 is used for a long time, the air supply pipeline 200 or the heat dissipation plate 100 can be blocked, so that the auxiliary defrosting device cannot be normally used. Relatively large impurities such as winged insects and paper scraps are sucked into the air supply pipeline 200, which directly causes the blockage of the air supply pipeline 200 or the heat dissipation plate 100, thereby affecting the abnormal operation of the auxiliary defrosting device.
The filter 210 is arranged at the first nozzle of the air supply pipeline 200, and air entering the air supply pipeline 200 is filtered, so that the normal use of the auxiliary defrosting device can be effectively ensured, and the service life of the auxiliary defrosting device can be prolonged.
Optionally, the auxiliary defrosting apparatus further includes an electric heating part 400 provided in the outdoor heat exchanger installation space for heating air in the outdoor heat exchanger installation space.
The electric heating part 400 is installed in the installation space of the outdoor heat exchanger, the electric heating part 400 heats the air in the installation space of the outdoor heat exchanger, and the air is heated by the electric heating part 400, so that the defrosting efficiency can be further improved, and the defrosting effect is further improved.
The electric heating part 400 of the embodiment of the present disclosure is used for heating air in the installation space of the outdoor heat exchanger, the electric heating part 400 may be a resistance wire or an electromagnetic coil, the setting form may be directly wound on the fan bracket 500 in the air conditioner outdoor unit, and may also be fixed by other parts, as long as the electric heating part 400 can be used for heating air in the installation space of the outdoor heat exchanger by the power supply, and the setting form and the installation mode of the electric heating part 400 are not specifically limited.
Alternatively, the electric heating part 400 includes two arc-shaped metal rings, which are respectively disposed at the air outlet sides of the air outlet holes 130 of the first heat dissipation plate 110 and the second heat dissipation plate 120, and are fixed in the installation space of the outdoor heat exchanger; and the resistance wire is wound on the arc-shaped metal ring.
As shown in fig. 5, two arc-shaped metal rings are respectively disposed at the air outlet sides of the air outlet holes 130 of the first heat dissipation plate 110 and the second heat dissipation plate 120, and are fixed in the installation space of the outdoor heat exchanger, and the resistance wire is wound around the arc-shaped metal rings. Such an arrangement facilitates the outdoor fan to blow heat to the outdoor heat exchanger 700, thereby increasing the defrosting speed.
Meanwhile, the heating range for heating the air in the installation space of the outdoor heat exchanger can be adjusted by setting the size of the arc-shaped metal ring. Thus, the heating range of the resistance wire is enlarged, and the limitation that the resistance wire is directly wound on the fan bracket 500 is effectively avoided. By the arrangement, the defrosting effect is further improved.
Optionally, the auxiliary defrosting device further comprises a temperature sensor disposed in the housing for detecting an outdoor temperature; and a controller configured to control the driving device 300 and the electric heating part 400 to be turned on according to the temperature detected by the temperature sensor in a case where the outdoor unit of the air conditioner is in a defrosting state.
The conventional air conditioner is generally provided with a defrosting mode, and the controller is configured to control the driving device 300 and the electric heating unit 400 to be turned on only when the outdoor unit of the air conditioner is in a defrosting state, so as to perform auxiliary defrosting on the outdoor unit of the air conditioner, thereby improving defrosting efficiency. Thus, energy consumption can be effectively reduced.
Under the condition that the outdoor environment temperature is low in winter, especially in areas with high humidity in winter, the outdoor unit of the air conditioner is easy to frost when the air conditioner heats. Therefore, whether the outdoor unit of the air conditioner is frosted or not depends on the outdoor ambient temperature.
Further, a temperature sensor is provided on the casing of the outdoor unit, and the controller is configured to control the driving device 300 and the electric heating part 400 to be turned on according to an outdoor temperature detected by the temperature sensor in a case where the outdoor unit is in a defrosting state. Thus, energy consumption can be effectively reduced.
Alternatively, in the case that the outdoor unit of the air conditioner is in the defrosting state, the controller controls the driving device 300 to be turned on when the temperature sensor detects that the outdoor temperature is lower than a first preset temperature, and controls the electric heating part 400 to be turned on when the temperature sensor detects that the outdoor temperature is lower than a second preset temperature; wherein the first preset temperature is higher than the second preset temperature.
The frosting degree and the defrosting efficiency are different according to different outdoor temperatures. The lower the temperature, the more severe the frost formation and the less efficient the defrosting.
Based on this, when the temperature sensor detects that the outdoor temperature is lower than the first preset temperature while the outdoor unit of the air conditioner is in the defrosting state, the controller controls the driving device 300 to be turned on. That is to say, when the outdoor temperature is higher than the second preset temperature but the first preset temperature, the driving device 300 is only required to be turned on to perform auxiliary defrosting on the air conditioner outdoor unit, and the defrosting effect can be effectively ensured.
When the temperature sensor detects that the outdoor temperature is lower than the second preset temperature, the controller controls the electric heating part 400 to be turned on. That is, when the outdoor temperature is lower than the second preset temperature, it is difficult to ensure the defrosting effect only by turning on the driving device 300, and at this time, the controller controls the electric heating part 400 to be turned on. The driving device 300 drives the air flow in the compressor installation space, the air with heat is conveyed to the heat dissipation plate 100 through the air supply pipeline 200, and is blown to the outdoor heat exchanger installation space from the air outlet 130 of the heat dissipation plate 100, so as to perform auxiliary defrosting on the air conditioner outdoor unit. Meanwhile, the electric heating part 400 electrically heats the air in the installation space of the outdoor heat exchanger, and the defrosting effect can be effectively guaranteed through the cooperation of the electric heating part and the air.
In the case where the outdoor unit of the air conditioner is in the defrosting state, the driving device 300 and the electric heating part 400 are controlled to be turned on according to the temperature, so that the power consumption can be effectively reduced.
The first preset temperature and the second preset temperature in the embodiment of the present disclosure may be set by a user, or may be factory settings, which is not specifically limited.
Optionally, the outdoor unit of the air conditioner comprises a casing, which is provided with an air inlet and an air outlet, and is provided with a compressor installation space and an outdoor heat exchanger installation space; an outdoor heat exchanger 700 disposed in the outdoor heat exchanger installation space; a compressor disposed in the compressor installation space; also included is the above-mentioned auxiliary defrosting device for an outdoor unit of an air conditioner, and a first nozzle of the air supply duct 200 is disposed in the compressor installation space.

Optionally, the outdoor unit of the air conditioner further includes a fan bracket 500 disposed in the installation space of the outdoor heat exchanger; the outdoor fan is arranged on the fan bracket 500 and used for driving outdoor air to enter the shell through the air inlet of the shell, exchange heat with the outdoor heat exchanger 700 and then be discharged to the outside through the air outlet of the shell; the soundproof cotton 600 wraps the compressor; wherein, the supply air duct 200 is fixed to the soundproof cotton 600 near the duct of the first nozzle, and is located between the soundproof cotton 600 and the compressor, the heat dissipation plate 100 is provided in the fan bracket 500, and the electric heating part 400 is provided in the fan bracket 500 under the condition that the auxiliary defrosting device is provided with the electric heating part 400.

The duct of the supply air duct 200 close to the first nozzle is fixed to the soundproof cotton 600, and is located between the soundproof cotton 600 and the compressor. With the arrangement, on one hand, the soundproof cotton 600 can play a role in heat preservation of the air supply duct 200, and effectively slows down the heat dissipation speed at a lower outdoor temperature. On the other hand, the air supply pipeline 200 is close to the compressor, and heat can be directly conducted to the air supply pipeline 200, so that heat loss is avoided.
In the embodiment of the present disclosure, the supply air duct 200 is fixed to the soundproof cotton 600 near the first orificial pipeline, can adopt sticky form, also can adopt magic tape's form, as long as can realize that the supply air duct 200 is close to the fixed of first orificial pipeline can, do not specifically limit this.
The heat radiating plate 100 and the electric heating part 400 are provided to the fan bracket 500, and the fan bracket 500 is located between the outdoor fan and the outdoor heat exchanger 700, so that the air with heat blown into the installation space of the outdoor heat exchanger through the air outlet 130 of the heat radiating plate 100 and the air in the installation space of the outdoor heat exchanger are electrically heated by the electric heating part 400 and blown to the outdoor heat exchanger 700 by the outdoor fan.
Thus, the heat can fully cover the outdoor heat exchanger 700, and the defrosting effect can be effectively ensured.
The heat dissipation plate 100 of the embodiment of the present disclosure is disposed on the fan bracket 500, and is configured to blow air with heat into the installation space of the outdoor heat exchanger, and the heat dissipation plate 100 may be disposed on one side of the fan bracket 500 facing the outdoor heat exchanger 700, or may be disposed on one side of the fan bracket 500 facing the outdoor fan, as long as the heat dissipation plate 100 can blow air with heat into the installation space of the outdoor heat exchanger, which is not specifically limited.
The electric heating part 400 of the embodiment of the present disclosure is disposed on the fan bracket 500, and is configured to electrically heat air in the installation space of the outdoor heat exchanger, and the electric heating part 400 may be directly wound on the fan bracket 500, or may be fixed to the fan bracket 500 through other parts, as long as the electric heating part 400 can electrically heat air in the installation space of the outdoor heat exchanger, which is not specifically limited to this.
Optionally, the fan support 500 is a metal material.
The heat-conducting property of the metal material is greater than that of the nonmetal material, the fan support 500 is made of the metal material, and therefore when the electric heating part 400 is a resistance wire and is directly wound on the fan support 500, the fan support 500 made of the metal material can electrically heat air in the installation space of the outdoor heat exchanger through the resistance wire to play a reinforcing role, and the defrosting effect can be effectively improved.
Alternatively, the arc-shaped metal ring of the electric heating part 400 is fixed to the fan bracket 500.
As shown in fig. 5, two arc-shaped metal rings are respectively disposed at the air outlet sides of the air outlet holes 130 of the first heat dissipation plate 110 and the second heat dissipation plate 120, and are fixed to the fan bracket 500, and the resistance wire is wound around the arc-shaped metal rings. Such an arrangement facilitates the outdoor fan to blow heat to the outdoor heat exchanger 700, thereby increasing the defrosting speed.
Meanwhile, the heating range for heating the air in the installation space of the outdoor heat exchanger can be adjusted by setting the size of the arc-shaped metal ring. Thus, the heating range of the resistance wire is enlarged, and the limitation that the resistance wire is directly wound on the fan bracket 500 is effectively avoided. By the arrangement, the defrosting effect is further improved.
