[0036] An auxiliary mechanism 5 is provided on one side of the condenser 28, and the auxiliary mechanism 5 includes a reversing valve 51, an auxiliary pipe 52 and a compressor assembly 53.

[0037] In this example, the internal space of the protective shell 21 can be divided by the partition plate 23, one side of the axial flow fan 24 is fixedly connected to the protective shell 21, and the side wall of the protective shell 21 is penetrated by the axial flow fan 24, and the external air can be accelerated to enter the protective shell 21 through the axial flow fan 24, so that the air passes through the pre-processor 25, the heating plate 251 is inclined, and a heating wire is installed inside, which can increase the contact area with the air and slow down the flow speed of the air, so that the heated air can pass through the pre-processor 25 and the left side of the filter box 22 to enter the filter box 22, and the multi-layer filter element 221 is installed inside the filter box 22, which can quickly filter the air and remove dust and other impurities in the air, thereby reducing the subsequent accumulation of dust and impurities inside the pipeline, and there is a gap between the air outlet at the bottom of the filter box 22 and the partition plate 23, and the air can be discharged through the air outlet and then enter the bottom of the partition plate 23 through the guide port on the partition plate 23, thereby changing the flow direction of the air, so that the gas flows inside the protective shell 21, and the water condensed by the condenser 1 27 and the condenser 2 28 can be collected by the collecting tank;

[0038] At the same time, the compressor assembly 53 is installed in the protective shell 21. The protective shell 21 can be used to wrap and protect the compressor assembly 53, so that the compressor assembly 53 can be used normally inside the protective shell 21. The reversing valve 51 can be used to connect the compressor assembly 53, the compressor assembly 53 and the drainage pipe 26, so as to adjust the flow direction of the Freon. At this time, since the air discharged from above the partition plate 23 is hot air, the protective shell 21 can be heated to assist in heating and adjust the operating temperature of the protective shell 21, thereby reducing the interference of low temperature on the use of the protective shell 21, thereby ensuring the normal use of the external unit assembly 2.

[0039] Embodiment 3: According to Figure 5-Figure 9 As shown, the outer ring surface of the protective tube 32 is provided with a mounting assembly 36, and the mounting assembly 36 includes a limiter 361, a fixing member 363 and a flat gear 367. A driving rod 369 is hinged on one side of the limiter 361, a rack 368 is hinged on one side of the driving rod 369, and a fixing member 363 is slidably connected to one side of the rack 368. One side of the fixing member 363 is connected to the protective housing 21 by bolts. A motor 362 is fixedly connected to the top of the fixing member 363, and one end of the output shaft of the motor 362 is fixedly connected to a bevel gear 2 366 One side of bevel gear 2 366 is meshed with bevel gear 1 365, one side of bevel gear 1 365 is fixedly connected with flat gear 367, one side of flat gear 367 is rotatably connected with fixing member 363, and the bottom of flat gear 367 is meshed with rack 368, one side of limit member 1 361 is fixedly connected with limit member 2 364, one side of the inner wall of limit member 2 364 is snap-connected with the outer annular surface of protective tube 32, the inner wall of limit member 1 361 overlaps with the outer annular surface of protective tube 32, and the outer annular surface of protective tube 32 is snap-connected with one side of fixing member 363.

[0040] In this embodiment, the protective housing 21 can be used to support one side of the fixing member 363, thereby improving the stability of the fixing member 363 during installation. The side of the fixing member 363 away from the protective housing 21 is connected to the protective tube 32, and can support one side of the protective tube 32, which is convenient for the initial placement of the protective tube 32 during installation. The motor 362 can provide power for the rotation of the bevel gear 2 366, thereby driving the bevel gear 2 366 to rotate on one side of the fixing member 363. One side of the fixing member 363 is rotatably connected to the flat gear 367. The fixing member 363 can be used to support one side of the flat gear 367, thereby improving the stability of the flat gear 367 and the bevel gear 1 365 during rotation. One end of the rack 368 can realize reciprocating motion inside the fixing member 363. The movement of the rack 368 can change the inclination angle of the driving rod 369, and can drive the limit member 361 to move up and down. Since the limit member 361 is slidably connected to the protective shell 21, the protective shell 21 can be used to guide the movement of the limit member 361, thereby limiting the movement range of the limit member 361. The inner wall of the limit member 361 is arc-shaped. The combination of the limit member 361 and the arc-shaped limit member 2 364 can increase the contact area with the protective tube 32, thereby assisting the connection between the protective tube 32 and the protective shell 21, and further supporting the installation and use of the protective tube 32.

[0041] The use method and working principle of this device are as follows: first, the motor 362 is used to drive the bevel gear 2 366 to rotate, and the bevel gear 2 366 is meshed with the bevel gear 1 365 to drive the bevel gear 1 365 and the flat gear 367 to rotate synchronously, and the bottom of the flat gear 367 is meshed with the rack 368 to drive the rack 368 to slide along one side of the fixing member 363. When the rack 368 moves toward the side close to the fixing member 363, the rack 368 applies a force to the driving rod 369, and the driving rod 369 drives the limiting member 1 361 to move downward along one side of the protective shell 21. At this time, the inner wall of the limiting member 1 361 overlaps with the outer annular surface of the protective tube 32, and the inner wall of the limiting member 2 364 is engaged with the top of the protective tube 32, so as to realize the limiting fixation of the protective tube 32 on one side of the protective shell 21;

[0042] The temperature sensor 37 can be used to detect the temperature change of the external environment. When the external environment is lower than the predetermined temperature, the control terminal determines that the current air conditioner needs to realize the heating function, and then the PLC controller inside the electric control box 35 is used to control the operation of the thermostatic tube 1 391 and the thermostatic tube 2 392 inside the protection tube 32 to heat the inside of the protection tube 32 and adjust the entire air conditioner to the heating state. The freon contained in the compressor assembly 53 can quickly generate high-temperature and high-pressure gas after being processed by the compressor assembly 53. The high-temperature gas enters the evaporator of the indoor unit assembly 1 and is cooled. Then, the medium-temperature freon gas enters the condenser 1 27 and the condenser 2 28 through the guide tube 1 33 and the guide tube 2 34 to realize cooling again, realize the overall operation of the air conditioner, and complete the heating process.

[0043] Solenoid valves are installed on connecting pipe 1 31, connecting pipe 2 311, guide pipe 1 33 and guide pipe 2 34, and the opening or closing state of the solenoid valves can be adjusted as needed. Since the temperature regulating plate 39 is made of heat-conducting material, it can achieve rapid heat transfer, and transfer the heat to the outside of guide pipe 1 33 and guide pipe 2 34, so as to heat and raise the temperature of guide pipe 1 33 and guide pipe 2 34. The high-temperature and high-pressure gas inside the compressor assembly 53 is sent into the drainage pipe 26 after passing through the reversing valve 51, and then enters the evaporator of the indoor unit assembly 1 after being transported through the drainage pipe 26, and then is discharged into connecting pipe 1 31 and connecting pipe 2 311 through the end of the evaporator. At this time, the outdoor unit assembly 2 is in normal working state, and the axial flow fan 1 24 draws external air into the protective shell 21, which is preliminarily heated by the heating plate 251 inside the pre-processor 25 to restore the air to about 20°C. The heated air enters the filter box 22 and is filtered by the multi-layer filter element 221, and then passes through The exhaust port at the bottom of the filter box 22 and the guide port at the top of the partition plate 23 enter the bottom of the partition plate 23 and reach the vicinity of condenser 1 27 and condenser 28, and start the collection hood 41. The collection hood 41 accelerates the flow of air inside the protective shell 21, and the air is collected into the recovery pipe 44 through the collection hood 41, and then heated by the heating sleeve 43, which can keep the temperature of the gas basically constant and reduce the heat loss of the recovery pipe 44 in the external cold air. The hot air is introduced into the flange pipe 38 through the recovery pipe 44, and then enters the inside of the protective tube 32. The hot air can be evenly distributed inside the protective tube 32 through the guide groove 393 opened at the bottom of the temperature regulating plate 39, so as to heat the temperature regulating plate 39 again. A valve is installed on the exhaust pipe installed at the bottom of the protective tube 32, and the air after heat exchange can be discharged through the exhaust pipe to realize gas circulation. In the above working process, since the guide pipe 1 33 and the guide pipe 2 34 are both wrapped by the temperature regulating plate 39 and the protective tube 32, the antifreeze effect can be improved.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
