In the existing compressor, the refrigeration capacity of the compressor is not more and more satisfied with the development requirement under the condition of consuming the same power (namely, consuming the same electric quantity), and the improvement of the energy efficiency ratio of the compressor is very important.

In the air suction and exhaust mode of the existing commercial rotary compressor pump, an air suction channel is arranged in a cylinder body of the rotary compressor pump. The pump is a sealed refrigerant compression space formed by parts of an upper support, a lower support, a cylinder body, a shaft, a ring and blades, in the space, if the cylinder body is designed as a suction channel, the amount of refrigerant entering the sealed space is constant, the amount of refrigerant compressed in the sealed compression space is also constant, the corresponding cooling room capacity, the consumed power and the energy efficiency ratio are constant, and the energy efficiency ratio cannot be improved. In order to improve the energy efficiency ratio and have a better refrigeration effect under the same power consumption, the cold room capability needs to be improved under the condition that the consumed power is not changed, or the improvement of the cold room capability is more than the improvement of the consumed power, and enterprises need to develop a novel air cylinder structure to improve the energy efficiency ratio of the compressor urgently.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that the energy efficiency ratio of the existing compressor is low, the speed of the air cylinder sucking the refrigerant is slow, the utility model provides a compressor air cylinder structure.

The utility model provides a compressor cylinder structure, includes the cylinder body, sets up the blade groove on the cylinder body, and sets up the inspiratory channel of blade groove one side, the cylinder body on be equipped with the centre bore, the inspiratory channel including radially lining up the horizontal channel of cylinder body to and link up the perpendicular passageway of cylinder body perpendicularly, horizontal channel and perpendicular passageway intercommunication, perpendicular passageway establish in handing-over department of horizontal channel and centre bore, horizontal channel intercommunication have the side passageway, side passageway and centre bore intercommunication.

Preferably, the centerlines of the horizontal and vertical channels overlap.

Preferably, the lateral channels communicate with the vertical channels.

Preferably, a connecting channel is arranged at the joint of the vertical channel and the side channel on the cylinder body, and the connecting channel is communicated with the vertical channel and the side channel.

Preferably, the surface of one side of the side channel adjacent to the vertical channel is the inner wall of the vertical channel.

Preferably, one side of the vertical channel, which is far away from the side channel, is provided with a groove, and the groove vertically penetrates through the cylinder body.

Preferably, the included angle between the air inlet directions of the side channels and the horizontal channel is an acute angle.

Preferably, the number of the vertical channels is 1-4.

The utility model increases the suction volume of the refrigerant, accelerates the inflow speed of the refrigerant, and can improve the cold room capability of the compressor with the cylinder body, thereby improving the energy efficiency ratio; compared with the existing single channel, the multiple channels (the vertical channel, the horizontal channel and the side channel) enable the refrigerant to flow more smoothly, and the power consumed by the refrigerant flowing is reduced; if some channels in the multiple channels are leaked, compared with the leakage of a single channel, the risk caused by refrigerant leakage is lower, and the influence on the performance of the compressor product is smaller; the connecting channel and the groove design enlarge the flowing space of the refrigerant, thereby improving the flowing speed of the refrigerant.
