Pump body structure, compressor and air conditioner

Abstract

The invention provides a pump body structure, a compressor and an air conditioner. The pump body structure comprises an exhaust cavity. The exhaust cavity is provided with a first exhaust channel anda second exhaust channel, and the first exhaust channel and the second exhaust channel can communicate with the exhaust cavity or be separated from the exhaust cavity. The opening and penetrating pressure of the second exhaust channel is higher than the opening and penetrating pressure of the first exhaust channel. By means of the pump body structure, the compressor and the air conditioner, when the exhaust resistance is too large during running of the compressor or overcompression exists, the exhaust resistance and the overcompression losses of the compressor are reduced through opening and penetrating and the second exhaust channel, torque fluctuation caused by unsmooth exhausting when exhausting is over is reduced, and airflow pulsation is reduced.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a pump body structure, a compressor and an air conditioner. Background technique [0002] The pump body assembly of the rolling rotor compressor is composed of a cylinder, a roller, a crankshaft, an upper and lower flange assembly (including an upper and lower flange, an exhaust valve plate and a valve plate limit baffle) and a sliding plate. A closed high-pressure chamber (exhaust chamber) and a low-pressure chamber (suction chamber) are formed, and the sliding vane cooperates with the sliding vane groove to reciprocate in the sliding vane groove, so that the volume of the high and low pressure chamber changes periodically, and the cylinder compression chamber approaches There is a cylinder exhaust port at the position of the sliding vane groove, and a flange exhaust port is provided at the corresponding position between the upper flange and the cylinder exh...

AI Technical Summary

Problems solved by technology

[0003] Due to the development trend of miniaturization of rotary compressors, the cylinder bore of the pump body is bound to be limited. Under the same displacement, the cylinder height increases relatively, which leads to a great increase in the exhaust resistance of the pump body, which can easily cause poor exhaust and over-compression of the pump body. As a result, the energy consumption of the compressor due to exhaust is relatively high, and in severe cases, abnormal shutdown of the compressor and other reliability problems will be caused due to excessive instantaneous torque fluctuations. Based on this problem, the present invention is proposed
