Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a novel compressor casing. Background Art

[0002] The compressor is a driven fluid machine that can boost low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it by driving the piston through the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption);

[0003] Chinese patent announcement No. CN202867227U discloses a novel compressor housing, which can prevent the stator and rotor from shaking by providing limit bodies on both sides of the interior of the upper housing. Therefore, the refrigerator compressor can be tilted more than 45°, which is more convenient to carry and less likely to cause damage. However, the lower housing structure in the above technology is not strong enough. In order to ensure the operation of the equipment, its wall thickness is large, which increases the volume and weight of the compressor and has a high manufacturing cost. In addition, the housing is directly contacted and fixed with the limit bodies, has no shock-absorbing effect, and causes serious noise pollution. Therefore, the utility model provides a novel compressor housing to solve the above problems. Utility Model Content

The reinforcing ribs are connected with the first positioning groove and the second positioning groove to form an integral structure, and shock absorbing parts are embedded in the first positioning groove and the second positioning groove.

[0007] Beneficial effects: The new compressor housing has rationally optimized the internal structure of the housing, added reinforcing ribs, reduced the volume and weight of the compressor, improved the overall strength of the compressor housing, saved the space occupied by the compressor in the whole machine, and reduced the manufacturing cost of the compressor. The positioning grooves are all equipped with built-in shock-absorbing parts, so that the internal motor can be centered and limited. During operation, the shock-absorbing parts can effectively reduce vibration and play a role in reducing the operating noise of the compressor.

[0008] Furthermore, the reinforcing ribs include longitudinal ribs, transverse ribs and connecting ribs connected between the longitudinal ribs and the transverse ribs, and the longitudinal ribs and the transverse ribs are perpendicular to each other.

[0009] Furthermore, an inward depression is provided on the bottom wall of the lower shell and is located in the fan-shaped space formed by the longitudinal ribs and the transverse ribs.

[0018] See Figures 1 to 3As shown, a novel compressor housing comprises an upper housing 1 and a lower housing 2, wherein the upper housing 1 covers the lower housing 2;

[0019] Specifically, the upper shell 1 and the lower shell 2 are both made of stainless steel, have good structural integrity, and are not easy to rust. The two can be threaded, flanged or welded.

[0020] Furthermore, the bottom inner wall of the lower shell 2 is provided with reinforcing ribs 3, and the reinforcing ribs 3 include longitudinal ribs 31, transverse ribs 32, and connecting ribs 33 connected between the longitudinal ribs 31 and the transverse ribs 32, and the longitudinal ribs 31 and the transverse ribs 32 are perpendicular to each other;

[0021] Specifically, the longitudinal ribs 31, the transverse ribs 32 and the connecting ribs 33 together form a grid structure, which improves the overall strength of the bottom of the lower shell 2, enables the wall thickness of the lower shell 2 to be reduced, reduces the volume and weight of the compressor, and reduces the production cost.

[0022] Furthermore, an inward recess 21 is provided on the bottom wall of the lower shell 2 and is located in the fan-shaped space formed by the longitudinal ribs 31 and the transverse ribs 32;

[0023] Specifically, the recess 21 can facilitate positioning during processing and can reduce the volume of the compressor.

[0024] Furthermore, a first positioning groove 4 is provided at the middle of the upper shell 1 and the lower shell 2, and the first positioning groove 4 is provided in a rectangular structure;

[0025] Specifically, the shock-absorbing member 6 in the first positioning groove 4 can reduce the up and down vibration of the internal motor. It is worth noting that the present application fixes the internal motor and the piston structure of the compressor as a whole so that the motor and the piston structure can vibrate as a whole.

[0026] Furthermore, a plurality of second positioning grooves 5 are provided on the inner peripheral wall of the lower shell 2, the opening of the second positioning groove 5 is upward, and a U-shaped slot is provided on the side wall thereof;

[0027] Specifically, the second positioning groove 5 is equidistantly arranged around the center of the lower shell 2, and the shock absorber 6 inside it can prevent the internal motor from vibrating back and forth and left and right, and the internal motor is tilted 45° and pressed on the shock absorber 6 in the second positioning groove 5, so that the shock absorber 6 will not fall out of the second positioning groove 5.

[0028] Furthermore, the reinforcing rib 3 is connected with the first positioning groove 4 and the second positioning groove 5 as an integral structure, and a shock absorbing member 6 is embedded in each of the first positioning groove 4 and the second positioning groove 5. The shock absorbing member 6 is made of rubber material, and the cross section of the shock absorbing member 6 is a "convex" shaped structure;
