Problems solved by technology
[0003] In the structure of the multi-cylinder rotary compressor, the diaphragm and the crankshaft are not in contact, especially in the multi-cylinder compressor, because there are more compressor units, the crankshaft is longer, the distance between the bearings at both ends is far, and the crankshaft is connected in the middle The part is thinner, and the middle part becomes the weak link of the crankshaft, which is easy to cause bending deformation during the working process, thus affecting the normal operation and reliability of the compressor. The plate has a single function, and after being assembled to the crankshaft, it not only occupies the volume of the compressor, but also increases the weight of the compressor

The invention discloses a multi-cylinder rotary compressor, comprising: a cylinder assembly, the cylinder assembly includes at least two cylinders arranged in the up and down direction, each cylinder has a compression chamber, and a partition is arranged between two adjacent cylinders. The plate, wherein the partition includes at least two first sub-baffles disposed in the circumferential direction of the cylinder assembly, at least one of the at least two first sub-baffles has a cavity therein; a main bearing and a sub-bearing; and a crankshaft. According to the multi-cylinder rotary compressor of the present invention, the cavity is provided in the partition, thereby reducing the weight of the partition and further reducing the weight of the multi-cylinder rotary compressor. Compared with the material of the partition, the gas in the cavity has a smaller thermal conductivity, so that the partition has better heat insulation and cooling effects. In addition, the cavity in the partition plate also has a good sound insulation effect, thereby effectively reducing the working noise of the multi-cylinder rotary compressor.
Description
technical field [0001] The present invention relates to the technical field of refrigeration equipment, in particular to a multi-cylinder rotary compressor. Background technique [0002] In the multi-cylinder rotary compressor, an electric element (motor) and a plurality of rotary compression elements are accommodated in a sealed container, and the electric element and the plurality of rotary compression elements are connected by a crankshaft having an eccentric portion. In addition, the spacer installed between the rotary compression elements is composed of at least two sub-spacers, assembled with the crankshaft inserted through the through hole provided in the split plate, and then the outer parts of the at least two sub-spacers are connected by connection or the like. The circle is fixed. It is possible to easily provide a multi-cylinder rotary compressor whose partition is divided into at least two sub-partitions so that there is a slight gap between the sub-partition p...
