Detailed implementation manners

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] A dual-fan outdoor unit of an air conditioner with a self-cleaning function, the outdoor unit of the air conditioner includes a frame 1, a capillary tube 2, and a compressor 3. The compressor 3 and the capillary tube 2 are respectively fixedly installed in the frame 1, and the compressor 3 is connected to the capillary tube 2. It further includes a vortex fan assembly 4, an axial flow fan assembly 5, and a self-cleaning assembly 6. The vortex fan assembly 4 is installed at the front end of the capillary tube 2, the axial flow fan assembly 5 is installed at the rear end of the capillary tube 2, and the self-cleaning assembly 6 is installed on the axial flow fan assembly 5. When the axial flow fan assembly 5 rotates forward, the self-cleaning assembly 6 fits with the axial flow fan assembly 5 and does not clean the capillary tube 2. When the axial flow fan assembly 5 rotates reversely, the self-cleaning assembly 6 is separated from the axial flow fan assembly 5, and the capillary tube 2 is brushed and cleaned. By providing the vortex fan assembly 4 and the axial flow fan assembly 5 in the outdoor unit of the air conditioner, it is convenient to cool the capillary tube 2 through the two fans, improving the cooling efficiency of the capillary tube 2. And by providing the self-cleaning assembly 6 on the axial flow fan assembly 5, the self-cleaning assembly 6 is controlled to clean the capillary tube 2 by controlling the forward and reverse rotation of the axial flow fan assembly 5, keeping the capillary tube 2 clean and facilitating the improvement of the cooling efficiency of the capillary tube 2.

[0026] The self-cleaning component 6 includes a motor mounting sleeve 7, a fan locking sleeve 8, and a brushing member 9. The motor mounting sleeve 7 and the fan locking sleeve 8 are coaxially arranged. The brushing member 9 is fixedly connected between the motor mounting sleeve 7 and the fan locking sleeve 8. The motor mounting sleeve 7 is slidably mounted on the axial flow fan assembly 5, and the capillary tube 2 can be brushed by the brushing member 9 according to requirements, maintaining the cleanliness of the capillary tube 2, thereby improving the cooling efficiency of the capillary tube 2.

[0027] The motor mounting sleeve 7 includes an axial flow motor mounting cylinder 10 and a sliding mounting cylinder 11. The axial flow motor mounting cylinder 10 is fixedly mounted on the sliding mounting cylinder 11. The sliding mounting cylinder 11 is slidably mounted on the axial flow fan assembly 5. The brushing member 9 is mounted on the sliding mounting cylinder 11. Through the setting of the sliding mounting cylinder 11, it is convenient for the self-cleaning component 6 to be telescopically mounted on the fan blade connecting sleeve 14, so that the capillary tube 2 can be brushed according to requirements. And through the setting of the axial flow motor mounting cylinder 10, the self-cleaning component 6 is driven to expand and contract.

[0028] The axial flow fan assembly 5 includes a fan assembly and an axial flow motor 12. The fan assembly is fixedly connected to the axial flow motor 12. The sliding mounting cylinder 11 is slidably mounted on the fan assembly. The axial flow motor mounting cylinder 10 is adapted to the axial flow motor 12. When the axial flow motor 12 rotates forward, the self-cleaning component 6 is driven to fit with the axial flow fan assembly 5. When the axial flow motor 12 rotates in reverse, the self-cleaning component 6 is driven to separate from the axial flow fan assembly 5, facilitating the brushing of the capillary tube 2 according to requirements.

[0029] The fan assembly includes a fan blade 13, a fan blade connecting sleeve 14, and a self-cleaning locking sleeve 15. The fan blade 13 is fixedly mounted between the fan blade connecting sleeve 14 and the self-cleaning locking sleeve 15. The self-cleaning locking sleeve 15 is adapted to the fan locking sleeve 8, facilitating the splicing and simultaneous rotation of the self-cleaning component 6 and the axial flow fan assembly 5 during forward rotation. The sliding mounting cylinder 11 is slidably connected to the fan blade connecting sleeve 14.

[0030] A connecting ring 16 is fixedly connected to the outer side wall of the fan blade connecting sleeve 14. An installation groove 26 is formed inside the sliding mounting cylinder 11. The connecting ring 16 is slidably mounted in the installation groove 26. An elastic member 17 is mounted between the end face of the installation groove 26 and the end face of the connecting ring 16. Through the setting of the elastic member 17, it is convenient to provide a certain thrust for the self-cleaning component 6 when the axial flow motor 12 rotates in reverse, facilitating the brushing and cleaning of the capillary tube 2 by the self-cleaning component 6.

[0031] The fan blade connecting sleeve 14 is fixedly installed on the motor shaft of the axial flow motor 12. A guide rod 18 is fixedly connected to the motor shaft of the axial flow motor 12. Correspondingly, a guide groove 19 is formed in the axial flow motor mounting cylinder 10. The guide rod 18 is slidably installed in the guide groove 19. Preferably, the guide groove 19 is spiral, which is convenient for driving the self-cleaning assembly 6 to move back and forth when the axial flow motor 12 rotates forward and backward.

[0032] The axial flow motor mounting cylinder 10 includes mounting sleeve units 20 that are spliced with each other. A guide groove 19 is formed in each mounting sleeve unit 20. A connecting portion 21 is fixedly connected to the end face of the mounting sleeve unit 20. A connecting groove 22 is formed on the outer side of the sliding mounting cylinder 11. The connecting portion 21 is fixedly connected to the connecting groove 22, which is convenient for the installation of the axial flow motor mounting cylinder 10 and enables the axial flow motor mounting cylinder 10 and the fan assembly to rotate simultaneously.

[0033] Locking inclined grooves 23 are formed on both the self-cleaning locking sleeve 15 and the fan locking sleeve 8. When the axial flow motor 12 rotates forward, the locking inclined grooves 23 of the self-cleaning locking sleeve 15 and the fan locking sleeve 8 fit together and lock with each other, and the self-cleaning assembly 6 and the axial flow fan assembly 5 rotate simultaneously. When the axial flow motor 12 rotates backward, the self-cleaning locking sleeve 15 and the fan locking sleeve 8 can rotate relative to each other, which is convenient for the separation of the self-cleaning locking sleeve 15 and the fan locking sleeve 8, so that the brushing member 9 touches the surface of the capillary tube 2.

[0034] The brushing member 9 includes a brushing rod 24 and a brush 25. The brush 25 is fixedly connected to the brushing rod 24. The brushing rod 24 is fixedly connected between the motor mounting sleeve 7 and the fan locking sleeve 8. The end of the brush 25 protrudes from the end face of the motor mounting sleeve 7.

[0035] The forward rotation of the axial flow motor 12 is used for air cooling the capillary tube 2, and the reverse rotation of the axial flow motor 12 is used for brushing the capillary tube 2. The forward rotation speed of the axial flow motor 12 is 1000 r / min, and the reverse rotation speed of the axial flow motor 12 is 100 r / min, so as to prevent damage to the capillary tube 2 during the brushing process.

[0036] The working principle of the self-cleaning assembly 6 in the present invention is as follows.

[0037] (1) When the axial flow motor 12 rotates forward, the guide rod 18 slides in the guide groove 19, so that the axial flow motor mounting cylinder 10 moves towards the fan assembly against the elastic force of the elastic member 17 until the self-cleaning locking sleeve 15 and the fan locking sleeve 8 lock with each other, and air cools the capillary tube 2.

[0038] (2) When the axial flow motor 12 rotates in reverse, the guide rod 18 slides within the guide groove 19, causing the axial flow motor mounting cylinder 10 to move away from the fan assembly. The self-cleaning locking sleeve 15 and the fan locking sleeve 8 separate from each other. The brush 25 comes into contact with the surface of the capillary line 2. At the same time, the elastic member 17 exerts a certain thrust on the self-cleaning assembly 6 to ensure that the brushing member 9 brushes the capillary line 2 more stably.

[0039] The eddy current fan assembly 4 includes a turbo fan 41 and an eddy current motor 42. The eddy current motor 42 is fixedly installed on the frame 1, and the turbo fan 41 is installed on the eddy current motor 42.
