Description

Structure for fixing compressor of air-conditioning unit and improvement of chassis structure for fixing compressor of air-conditioning unit

The invention relates to a structure for fixing a compressor of an air conditioner, and an improvement of a chassis structure of an air conditioner for fixing the compressor.

An air conditioner is a common indoor environment control device, which is often used to adjust indoor temperature, humidity, air cleanliness, etc., so as to improve the comfort and cleanliness of the indoor environment. Air conditioners include common cooling/heating machines, dehumidifiers, etc., and their working principles are roughly the same. That is to say, the air conditioner generally utilizes the characteristics of the refrigerant dissipating heat in the condensation stage of the compression-condensation-expansion-evaporation cycle and absorbing heat in the evaporation stage to cool and dehumidify the air flowing through the air conditioner. In the above-mentioned refrigerant cycle of the air conditioner, the compressor plays a key role. In detail, the air conditioner uses a compressor to compress the gaseous low-pressure and low-temperature refrigerant in the refrigerant pipeline, turning it into a high-pressure and high-temperature gaseous refrigerant (compression stage), and then makes the high-pressure and high-temperature gaseous refrigerant flow through the condenser to dissipate heat to condense into a high-pressure refrigerant. The normal temperature liquid refrigerant (condensation stage), then the high pressure normal temperature liquid refrigerant flows through the expansion valve to expand and reduce the pressure to form a low-pressure low-temperature liquid-gas mixed refrigerant (expansion stage), and then the low-pressure low-temperature liquid-gas mixed refrigerant flows through evaporation and heat absorption to transform into a low pressure Low-temperature gaseous refrigerant (evaporation stage), and finally circulates back to the compressor to complete the entire cycle. Therefore, a compressor is a vital component in an air conditioning unit. Therefore, it is an important subject for the air conditioner to firmly and safely fix the compressor in the air conditioner so that it can run smoothly and efficiently.

3 and 4 respectively show an exploded perspective view and an assembled perspective view of a conventional structure for fixing a compressor in an air conditioner. As shown in Figures 3 and 4, this fixing structure includes three fixing pieces 11 formed on the body of the compressor 1 (only two fixing pieces 11 are shown), and each fixing piece is provided with a perforation 12, three The metal embedding bolts 14 corresponding to the through holes 12 of the fixing parts 11 formed on the chassis 13 of the air conditioner are placed in the mold when the plastic injection molding of the chassis of the air conditioner is made so that they are buried in the chassis when the chassis is formed. Among them, the upper end of each metal buried bolt 14 is formed with an external thread 15 and three cylindrical anti-vibration rubber parts 16, each anti-vibration rubber part 16 is provided with a central perforation 17 and each anti-vibration rubber part 16 can be inserted through Pass through the through hole 12 of the fixing part 11 and three nuts 18 . When assembling, first insert the anti-vibration rubber part 16 through the perforation 12 of the fixing part 11 on the compressor 1, and then put the anti-vibration rubber part 16 embedded on the compressor 1 into the metal buried shot on the chassis of the air conditioner. On the bolt 14, finally tighten the nut 18 on the external thread 15 on the upper end of the metal buried bolt 14 and thereby fix the compressor 1 to the chassis 13 of the air conditioner, as shown in FIG. 4 .

In addition, FIG. 5 and FIG. 6 respectively show an exploded perspective view and an assembled perspective view of another conventional structure for fixing the compressor 1 in the air conditioner. As shown in Figures 5 and 6, this fixing structure includes three fixing pieces 11 formed on the body of the compressor 1 (only two fixing pieces 11 are shown), and each fixing piece is provided with a perforation 12, three Formed on the chassis 13 of the air conditioner is a fixing post 20 corresponding to the perforation 12 of the fixing part 11. Each fixing post 20 is formed with a central screw hole 19 and three cylindrical anti-vibration rubber parts 16. Each anti-vibration rubber part 16 A central through hole 17 is formed, and each anti-vibration rubber part 16 can be inserted through the through hole 12 of the fixing part 11 and three screws 21 . When assembling, first insert the anti-vibration rubber part 16 through the perforation 12 of the fixing part 11 on the compressor 1, and then set the anti-vibration rubber part 16 embedded on the compressor 1 on the fixing post 20 on the chassis of the air conditioner Finally, lock the screw 21 into the central screw hole 19 of the fixing column 20 and thereby fix the compressor 1 to the chassis 13 of the air conditioner, as shown in FIG. 6 .

Although the above conventional structures for fixing the compressor in the air conditioner can achieve the function of fixing the compressor, they still have disadvantages to be solved. For example, in the above-mentioned conventional fixing structures, the shaft diameters of the metal buried bolts, fixing columns and screws are small, so when subjected to lateral impact, great stress will be caused to the metal buried bolts, fixing columns and fixing screws, making the fixing There is a risk of breaking the posts, fixing posts and fixing screws and causing the compressor to come loose.
