Embodiment 1

[0029] Such as Figure 2 to Figure 5 , Figure 8 , Figure 9 As shown, a cylinder block with an airfoil structure for a refrigeration compressor includes a base body 1 and a cylinder head 2 for externally connecting cylinder accessories, and also includes an airfoil block 5. The cylinder block is integrally enclosed by an upper shell and a lower shell. body in a casing. Base body 1 is high in periphery and low in the center, and a crankshaft drive shaft enters through the shaft hole 11 in the center of base body 1. A crankshaft 12 is arranged at the top of the crankshaft drive shaft. The piston hole 10 at the end where the head is located reciprocates, and the piston hole 10 extends to the back of the cylinder head 2. The back side of cylinder head 2 is connected with cylinder accessories such as muffler 18, cylinder head 16 through valve plate 17. The cross section of the cylinder head 2 is rectangular, the cylinder head 2 is connected with the base body 1 through bolts, ...

Embodiment 2

[0032] Such as Figure 6 , Figure 7 As shown, the connecting rod 13 is provided with a front-stage baffle 19, the top surface of the front-stage baffle 19 is as high as the top surface of the airfoil block 5, and the top surface of the connecting rod 13 is provided with a dovetail-shaped chute 21 with a small bottom and a large bottom. , the front-stage baffle plate 19 is arc-shaped and its bottom is fixed on a slider 22, and the slider 22 is slidably embedded in the chute 21, so that the front-stage baffle plate 19 is slidably connected to the top surface of the connecting rod 13, and the chute 21 A spring 20 is arranged inside, and one end of the spring 2 abuts against the crankshaft end of the chute 21 , and the other end abuts against the slider 22 , so that the front-stage baffle plate 19 slides toward the direction of the piston 15 . The base 1 on both sides of the cylinder head 2 is not provided with foot installation grooves 4, and the installation feet 9 are directl...

Embodiment 3

[0035] The cross section of the cylinder head 2 is trapezoidal, and the airfoil block 5 is a machined part. All the other are with embodiment 1.

Abstract

The invention discloses an airfoil structure cylinder seat for a refrigeration compressor, which includes a base body and a cylinder head for externally connecting cylinder accessories, the cylinder head is connected with the base body, and the cylinder seat also includes an airfoil block connected to the cylinder head on, and the airfoil block is located between the base body and the circumscribed cylinder. Since the airfoil block is set between the base body and the external cylinder, the oil splashed from the high-speed crankshaft to the direction of the cylinder head will be blocked by the airfoil block, and the blocked oil will flow to the left and right along the bottom of the airfoil block On both sides, it can effectively reduce the amount of oil splashed to the assembly area of ​​the cylinder assembly and the joint between the base body and the cylinder head, and prevent the oil circulation from being out of control.

Description

technical field [0001] The invention relates to a refrigeration compressor, more specifically, it relates to an airfoil structure cylinder seat for a refrigeration compressor. Background technique [0002] In the field of refrigeration compressors, piston reciprocating compressors are widely used. With the implementation of new energy consumption standards, the power consumption requirements for household appliances refrigerators continue to increase, and new requirements are also put forward for the energy consumption of compressors, the heart of refrigerators. Such as figure 1 As shown, inside the compressor, the cylinder block mainly includes a base body and a cylinder head, and the cylinder head is one of the main working areas of the cylinder block. In recent years, with the in-depth research on the performance of refrigerators, it has been found that too much refrigerated oil mixed into the refrigerant to participate in the refrigeration cycle will have side effects ...
