Abstract
Description
Technical Field
[0001] The utility model relates to the field of compressors, in particular to a cylinder head capable of improving efficiency and optimizing starting capability. Background Art
[0002] The compressor is a mechanical device that can raise low-pressure gas to high-pressure gas. It sucks low-temperature and low-pressure refrigerant gas from the intake pipe, compresses the piston driven by the motor, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle.
[0003] When the compressor is running, during the exhaust process, the gas is discharged from the cylinder and enters the inner cavity of the cylinder head through the exhaust valve plate, then enters the exhaust cavity through the exhaust hole on the cylinder seat, and finally exits the compressor through the exhaust coil. Therefore, the size of the inner cavity of the cylinder head affects the volume of the incoming gas. A smaller inner cavity of the cylinder head is not conducive to the working performance of the compressor.
[0004] In the prior art, the cylinder head and the cylinder seat are connected mainly by bolt mounting holes arranged at the four corners of the cylinder head, and the cylinder head can be firmly mounted on the cylinder seat by four bolts. However, the bolt mounting holes occupy the inner cavity volume of the exhaust cavity and the intake cavity of the cylinder head, which is not conducive to the working performance of the compressor. Summary of the invention
[0005] The utility model aims to provide a cylinder head with improved efficiency and optimized starting capability in view of the problems existing in the prior art, wherein the cylinder head can increase the inner cavity volume of the exhaust cavity and the intake cavity, and effectively improve the working performance of the compressor.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A cylinder head for improving efficiency and optimizing starting capability, comprising a cylinder head body, wherein the cylinder head body is provided with independent and connected intake chamber and exhaust chamber, and an intake muffler connection port located outside the intake chamber and the exhaust chamber, wherein a partition is provided in the intake chamber, wherein the partition divides the intake chamber into a main chamber located in the middle and a buffer chamber located on the side, wherein a first mounting platform is provided in the buffer chamber, wherein a first threaded hole is provided on the first mounting platform, wherein the main chamber is adjacent to the exhaust chamber, wherein a second mounting platform is provided in the exhaust chamber, wherein a second threaded hole is provided on the second mounting platform, and wherein a plurality of mounting holes are provided on the cylinder head body at corners away from the first threaded hole and the second threaded hole.
[0008] In the above technical solution, during the operation of the compressor, high-temperature and high-pressure gas moves in the exhaust chamber and the intake chamber. By setting threaded holes in the exhaust chamber and the intake chamber, compared with the traditional cylinder head, this structure increases the volume of the exhaust chamber and the intake chamber to accommodate gas, reduces the starting resistance of the compressor, and thus improves the working performance of the compressor.
[0009] On the basis of the above technical solution, preferably, the upper surface of the first mounting platform is lower than the mounting plane of the cylinder head body, and the upper surface of the second mounting platform is lower than the mounting plane of the cylinder head body.
[0010] In the above technical solution, the first mounting platform and the second mounting platform are lower than the mounting plane of the cylinder head body, which reduces the volume of the first mounting platform and the second mounting platform and can effectively increase the inner volume of the exhaust chamber and the intake chamber.
[0011] On the basis of the above technical solution, preferably, the mounting holes are symmetrically arranged on both sides of the air intake muffler connection port.
[0012] In the above technical solution, the mounting holes are symmetrically arranged on both sides of the intake muffler connection port to ensure the airtightness of the structure, while making the cylinder head bear the force evenly and improving the connection stability.
[0013] On the basis of the above technical solution, preferably, an arc-shaped recess is provided on the side of the cylinder head body, and the mounting hole is arranged in the arc-shaped recess.
[0014] In the above technical solution, the nuts and washers required for bolt installation are circular structures, and the arc shape of the arc-shaped recessed platform better fits the shape of the bolt washers, reducing the waste of excess space, thereby increasing the inner cavity volume of the exhaust cavity and the intake cavity.
[0015] On the basis of the above technical solution, preferably, an auxiliary baffle is provided in the cylinder head body, and the auxiliary baffle is connected to the inner wall of the main cavity near the intake muffler connection port.
[0016] In the above technical solution, after the high-temperature and high-pressure gas enters the intake chamber, the auxiliary baffle can mitigate the impact of the gas on the cylinder head body, thereby achieving the effect of reducing noise.
[0017] On the basis of the above technical solution, preferably, the auxiliary baffle is connected to the air intake muffler connection port, and the auxiliary baffle and the baffle divide the air intake cavity into a circuitous structure.
[0018] In the above technical solution, high-temperature and high-pressure gas enters the intake chamber and moves. By setting the intake chamber as a circuitous structure, the movement path of the high-temperature and high-pressure gas is increased, and the impact of the gas in the intake chamber on the cylinder head body is further alleviated, thereby achieving the effect of reducing noise.
[0019] On the basis of the above technical solution, preferably, ventilation grooves or ventilation holes are provided on the inner walls of the main cavity and the exhaust cavity, and the ventilation grooves or ventilation holes are arranged obliquely.
[0020] In the above technical solution, when high-temperature and high-pressure gas passes through the ventilation groove or ventilation hole, the oblique setting can change the gas flow direction, increase the gas propagation path, and slow down the impact of the gas in the exhaust chamber on the cylinder head body, thereby further achieving the effect of reducing noise.
[0021] On the basis of the above technical solution, preferably, a groove is provided on the inner side of the air intake muffler connecting port.
[0022] In the above technical solution, the groove provided on the inner side of the air intake muffler connection port facilitates the installation and positioning of the air intake muffler.
[0023] On the basis of the above technical solution, preferably, the intake muffler connection port is located at the lower half of the cylinder head body and a bottom plate is provided thereat.
[0024] In the above technical solution, by providing the bottom plate, the airtightness of the air intake silencer connection port is improved to prevent gas leakage.
[0025] Compared with the prior art, the present invention has the following beneficial effects:
[0026] 1. The utility model sets screw holes in the exhaust chamber and the intake chamber of the cylinder head body, thereby increasing the inner volume of the exhaust chamber and the intake chamber, reducing the starting resistance of the compressor, and effectively improving the working performance of the compressor; 2.
