Description

Support structure and compressor

Technical Field

The utility model relates to a compressor technical field, concretely relates to supporting structure and compressor.

Background

At present, the horizontal rotary compressor is mainly used for freezing and refrigerating equipment such as small refrigerators, showcases, island cabinets and the like, can also be used for room air conditioners and vehicle-mounted air conditioners, and has a wide application range.

Compared with a vertical rotary compressor, the horizontal rotary compressor can greatly reduce the overall height of the unit and has more advantages in application space. Meanwhile, as the compressor is horizontally arranged, the gravity center of the unit is reduced, the vibration of the tubing is reduced, the noise of the whole machine is reduced, and the reliability and the experience effect of the product are improved.

As shown in fig. 1 and 4, the horizontal compressor mainly comprises a horizontal compressor body 1, a liquid distributor 2 and a mounting assembly 3. As shown in fig. 5 and 6, the horizontal compressor body includes a housing assembly 4, and a motor unit 5 and a compression unit 6 sealed in the housing assembly 4, the housing assembly 4 includes an upper cover, a lower cover and a housing, the motor unit 5 and the compression unit 6 are connected by a crankshaft 61, the motor unit 5 is used as a power source, and the crankshaft 61 drives the compression unit 6 to complete the work of compressing the refrigerant. The compression section 6 includes a crankshaft 61, an upper bearing 62, a cylinder 63, a roller 64, a lower bearing 66, and a vane 67, and the upper bearing 62 and the lower bearing 66 are fixed to the cylinder 63 by screws 65.

As shown in fig. 5 to 7, the operation principle of the compressor is as follows: the refrigerant is sucked through the air suction port of the liquid separator and then subjected to gas-liquid separation, the gaseous refrigerant is sucked into the working cavity 631 (shown as a shaded part in fig. 7) of the cylinder, and the liquid refrigerant is retained in the liquid separator and vaporized after absorbing heat. Under the drive of the motor part 5, the crankshaft 61 rotates, the eccentric cam 611 on the crankshaft 61 drives the roller 64 to eccentrically rotate in the working cavity of the air cylinder, so as to compress the refrigerant, the refrigerant is compressed into high-temperature and high-pressure gas, then the high-temperature and high-pressure gas is discharged through the flange exhaust port, and finally the high-temperature and high-pressure gas flows through the motor part and then is discharged out of the compressor through the exhaust pipe.

As shown in fig. 1 and 4, the liquid distributor adopts a horizontal (horizontal) arrangement, which has the advantage of being able to use a vertical liquid distributor bracket, and is easy to install, but the liquid distributor adopts a horizontal arrangement, which results in the liquid distributor being too long in axial direction of the compressor body, the suction copper pipe 21 of the liquid distributor and the installation foot screw right below the suction copper pipe are in the same vertical plane, when the compressor is installed in the air conditioning system, the installation component is connected with the air conditioning system through the installation foot screw, and the installation foot screw is vertically screwed on the installation component and the air conditioning system by a tool, so that the tool interferes with the suction copper pipe 21 of the liquid distributor, and the assembly process and quality are affected.

In order to solve the problems, a horizontal type liquid distributor is changed into a vertical type liquid distributor (as shown in fig. 8 and 9), at the moment, a vertical type liquid distributor bracket (as shown in fig. 2 and 3) is still adopted as the material of the universal liquid distributor bracket, at the moment, the liquid distributor is vertically installed with the compressor body, the first side of the liquid distributor bracket is in surface contact with the liquid distributor, the second side of the liquid distributor is in line contact with the shell, or is not in surface contact, and the liquid distributor bracket cannot be attached to the liquid distributor and the shell simultaneously. If the liquid distributor and the shell are installed at other angles, the vertical liquid distributor support cannot be in line contact with the shell, and even cannot be in surface contact with the shell, and the liquid distributor support cannot be attached to the shell simultaneously. Consequently, when knockout and compressor body are arbitrary angle installation, knockout and casing can't laminate simultaneously to the knockout support, and the laminating degree of knockout support and casing is poor or the contact cooperation is poor, and then leads to the fixity poor also to install the location nature poor, and stability is low, and it is poor to connect the rigidity, influences the knockout vibration transmission, leads to the knockout vibration noise variation.
