Embodiment 1

[0036] figure 1 Shown are a rotary compressor 1A in stable operation and an air-conditioning cycle device (such as a refrigeration cycle device) equipped with the compressor 1A. The airtight high-pressure casing 2 of the compressor 1A includes a motor 5 , a compression mechanism unit 5 driven by the motor 6 , and lubricating oil 8 . The motor 6 is composed of a stator 6 a fixed to the inner periphery of the housing 2 and a rotor 6 b fixed to the crankshaft 35 . The power terminal 38 at the upper end of the housing 2 is connected to the stator 6a.

[0037] The compression mechanism part 5 is mainly made up of the following parts: the first cylinder 11, the second cylinder 12, the intermediate partition 25 connecting the two cylinders in the middle of the two cylinders, the first compression chamber 11a and the second compression chamber 12a at the center of the cylinder, The main bearing 20 and the auxiliary bearing 22 that seal the compression chamber and slide with the cran...

Embodiment 2

[0063] Figure 8 Rotary compressor 1B is shown in operation. In the compressor 1B, compared with the compressor 1A of the first embodiment, the spring for pressing the second slide plate 16b is omitted. In addition, the feature is that the magnet 18 is fixed to the second air cylinder 12 on the back of the second slider 16b. In the multi-cylinder rotary compressor, the design of canceling at least one spring of the sliding vane belongs to the known technology, and will not be repeated here.

[0064] At the same time when the rotary compressor 1B is restarted, the first sliding vane 16a starts, and after the internal pressure of the shell 2 rises, the internal pressure of the first compression chamber 11a and the second compression chamber 12a is lower than the pressure of the shell 2, and the pressure difference makes the second Slider 16b is activated. Therefore, the refrigeration cycle airflow of compressor 1B and figure 1 Example 1 shown is the same.

Abstract

The invention discloses a compressor and a refrigeration cycle device. The compressor includes a motor and a compression mechanism part driven by the motor in a sealed shell having an exhaust pipe opening, wherein a plurality of cylinders are arranged in the compression mechanism part; each cylinder is provided with a compression chamber, a rotor which revolves in the compression chamber, and a slip sheet which moves by revolution of the rotor; after the motor is stopped, gas in the shell flows into a reservoir connected with the compression cavities; and after the motor is started, the gas inthe reservoir flows into the compression cavities. According to the compressor disclosed by the invention, after the motor is stopped, the gas in the shell flows into the reservoir connected with thecompression cavities, so that the pressure of the shell can be quickly reduced to be equal to the pressure of the reservoir, and the restarting time of the compressor and the stabilizing time of a refrigeration cycle are greatly shortened.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor and a refrigeration cycle device. The present invention relates to a technique for shortening the restart time of a multi-cylinder rotary compressor mounted on an air conditioner and stabilizing a refrigeration cycle after restarting. This technology can improve the capacity control and annual power efficiency (APF) of air conditioners. Background technique [0002] The air conditioner can control the room temperature and perform defrosting operation, so the rotary compressor will frequently start and stop repeatedly. At this time, the internal pressure of the rotary compressor whose shell pressure is high pressure must be equal to the suction pressure of the evaporator before the motor can be started. In addition, there is a problem that it takes a long time for the air conditioner to enter a stable state after activation. [0003] For example, it takes 3 to ...
