Description

Technical Field

[0001] The invention relates to the field of air conditioner outdoor unit components, in particular to an air conditioner refrigeration component. Background Art

[0002] The air conditioning refrigeration components mainly include compressors, condensers, throttling devices and evaporators. The refrigeration principle is that the compressor compresses the refrigerant into high-pressure saturated gas. After the gaseous refrigerant is condensed by the condenser, it is throttled by the throttling device and then passed into the evaporator to cool the medium to be cooled for heat exchange. After the heat exchange, the refrigerant in the evaporator serpentine tube becomes low-pressure vapor and returns to the compressor, which is compressed by the compressor again. This is a refrigeration cycle. Among them, the condenser and compressor are generally integrated into the external unit of the air conditioner.

[0003] However, the condenser of the traditional air-conditioning refrigeration component only has a layer of protective net installed at the air inlet. Although the protective net is set relatively densely, after a long time of use, the continuous air intake will cause a lot of dust to stick to the surface of the condenser tube. Moreover, if the living environment is dusty, the surface of the condenser tube will be more easily covered with dust, affecting the cooling effect of the refrigeration component.

[0004] Therefore, it is particularly important to design an air conditioning refrigeration component to solve the above-mentioned defects. Summary of the invention

A compressor assembly 4 is installed at the right end of the external housing 1, a protective shell 5 is installed at the top of the external housing 1, an opening is opened at the bottom of the protective shell 5 to communicate with the inside of the external housing 1, a driving assembly 6 is installed inside the protective shell 5, and a plurality of groups of brush plates 7 are installed at the bottom of the driving assembly 6 and in front of the condenser 2, and the brush surface of each brush plate 7 is in contact with the condenser 2, and the driving assembly 6 is used to drive the brush plate 7 to remove dust from the condenser 2. An air guide hood 8 is installed on the top of the outer housing 1, located behind the protective shell 5. The front side of the air guide hood 8 is opposite to the back side of the protective shell 5. One end of the air guide hood 8 is connected to the outer housing 1, and the other end of the air guide hood 8 leads to the external environment of the outer housing 1 and is installed with an air suction hood 9.

[0015] The driving assembly 6 includes a mounting plate 601, a turntable 602, a transmission gear rack 603, a connecting column 604, a sliding rod 605 and a gear block 606, wherein the turntable 602 and the transmission gear rack 603 constitute a crank rotation guide rod mechanism, the turntable 602 serves as a rotating part of the crank rotation guide rod mechanism, and the transmission gear rack 603 serves as a guide rod of the crank rotation guide rod mechanism; the sliding rod 605 is connected to the transmission gear rack 603 as a reciprocating member.

[0016] Specifically, the mounting plate 601 in the driving assembly 6 is fixedly installed on the back side of the protective shell 5, and the turntable 602 is rotatably connected to the upper front part of the mounting plate 601 through the rotating shaft 607. The rotating shaft 607 passes through the back side of the protective shell 5 and extends into the wind guide cover 8. The wind guide cover 8 is provided with an impeller 608, and the impeller 608 is coaxially fixed to the penetration part of the rotating shaft 607, thereby making the turntable 602 as a rotating part in the crank rotating guide rod mechanism coaxially fixedly connected with the impeller 608.

[0017] A connecting column 604 is eccentrically fixed to the front of the rotating disk 602. The transmission gear rack 603 has a long groove. The connecting column 604 of the rotating disk 602 is inserted into the long groove of the transmission gear rack 603. The bottom of the transmission gear rack 603 forms an arc-shaped tooth portion.

[0018] A plurality of sleeves 609 are fixed to the lower front part of the mounting plate 601 in the driving assembly 6, and each sleeve 609 is distributed in the horizontal direction. The slide rod 605, which serves as a reciprocating member, is slidably installed in each sleeve 609. The upper end of each brush plate 7 is fixedly connected to the lower side of the slide rod 605. The upper side of the slide rod 605 has a tooth portion 606. The tooth portion at the bottom of the transmission gear rack 603 is in transmission engagement with the tooth portion 606 on the upper side of the slide rod 605, thereby connecting the slide rod 605 to the transmission gear rack 603.

[0019] When the turntable 602 in the crank guide rod mechanism rotates, the transmission gear rack 603 is driven to swing back and forth under the connection of the connecting column 604, and then the sliding rod 605 is driven to slide back and forth linearly left and right through the transmission gear rack 603, thereby driving the brush plate 7 to reciprocate to brush off the dust on the surface of the condenser 2.

[0020] In this embodiment, a dustproof net is installed in the air suction cover 9. When the compressor assembly 4 and the condenser 2 inside the outer housing 1 are working, the fan 3 rotates continuously to suck the wind from the air inlet on the back of the outer housing 1 into the inner side of the outer housing 1. At the same time, the wind is also sucked into the inner side of the air guide cover 8 from the air suction cover 9, providing a continuous power for the driving assembly 6, and filtering the air through the dustproof net in the air suction cover 9. After the air enters the air guide cover 8, the impeller 608 rotates, and the impeller 608 drives the rotating shaft 607 to rotate, thereby driving the rotating disk 602 to rotate, thereby causing the crank rotation guide rod mechanism to drive the sliding rod 605 to reciprocate linearly, and the wind energy generated by the fan 3 is used to automatically clean the surface of the condenser 2, saving energy while preventing the surface of the condenser 2 from being stained with dust, thereby improving the refrigeration effect of the refrigeration assembly.

[0021] In this embodiment, mounting seats 101 are fixedly installed at both left and right ends of the bottom of the external unit casing 1, and an inspection door 102 is rotatably connected to the right side of the external unit casing 1. The rear end of the inspection door 102 is fixedly connected to the external unit casing 1 through a lock 103. The external unit casing 1 is fixedly installed through the mounting seat 101, and the inspection door 102 can be quickly released through the lock 103, and then the inspection door 102 can be rotated to open it, so that the interior of the external unit casing 1 can be easily inspected.

[0022] In this embodiment, a protective net 105 is fixedly installed on the front of the outer housing 1 and outside the air outlet 104, a filter net 106 is installed on the inner side of the air inlet on the back of the outer housing 1, and a collection box 107 is installed inside the outer housing 1 and below the brush plate 7. When the fan 3 is working, the external air is sucked into the outer housing 1 through the air inlet, and the external air enters the outer housing 1 from the air suction cover 9 and the air inlet guide cover 8. When the wind passes through the condenser, it exchanges heat with the condenser and is finally exhausted from the air outlet 104. The protective net 105 is used to provide protection for the fan 3, and the filter net 106 is used to filter the inhaled air. At the same time, the suction force generated by the fan 3 causes the impeller 608 to rotate, so that the drive assembly 6 drives the brush plate 7 to brush off the dust on the surface of the condenser 2, and the removed dust falls into the collection box 107 for collection, which is convenient for cleaning.

[0023] In this embodiment, the bottom of the protective shell 5 is fixedly connected to the external machine housing 1, and a front cover plate 501 is installed on the front of the protective shell 5. The four corners of the front cover plate 501 are fixedly connected to the protective shell 5 by screws. The front cover plate 501 can be disassembled to inspect the internal drive component 6.

[0024] In this embodiment, the implementation scenario is specifically as follows: when the compressor assembly 4 and the condenser 2 inside the external unit casing 1 are working, the fan 3 continuously rotates to suck wind from the back of the external unit casing 1 into the inner side of the external unit casing 1. At the same time, the wind is also sucked into the inner side of the wind guide hood 8 from the air suction hood 9, and the air is filtered through the dustproof net. Then, the air enters the inner side of the wind guide hood 8 and drives the rotating shaft 607 to rotate through the impeller 608, thereby driving the turntable 602 to rotate. When the turntable 602 rotates, it drives the transmission gear rack 603 to swing left and right under the connection of the connecting column 604, and drives the sliding rod 605 to slide left and right under the connection of the tooth block 606, thereby driving the brush plate 7 to reciprocate and brush away the dust on the surface of the condenser 2. The entire operation process is simple and convenient. Compared with the existing air-conditioning refrigeration components, the present invention is designed to utilize the wind energy generated by the operation of the fan 3 to automatically clean the surface of the condenser 2, thereby saving energy and preventing the surface of the condenser 2 from getting dusty, thereby improving the refrigeration effect of the refrigeration component.
