Description

Multi-slide compressor and segmented compression method

The invention relates to a multi-slide type compressor and a sectional compression method, in particular to a rotary compressor adopting a corresponding sliding blade setting structure, which uses segmented exhaust gas to reduce the output power consumption required when the rotor is running. Wear and improve the working life of the compressor.

Compressors are devices that must be used in equipment such as air conditioners or air conditioners. Rotary compressors can be applied to small or micro-compressors due to the following characteristics due to the advancement of precision machining technology. More widely, the current small or micro-rotary compressors mostly use rolling rotor type: (1) few parts, simple structure; (2) less vulnerable parts, reliable operation; (3) no suction valve, The gap volume is small and the gas transmission coefficient is high; (4) in the case of the same cooling capacity, the compressor is small in size, light in weight and balanced in operation; (5) low power consumption and low noise required for operation; (6) machining accuracy The requirement is higher; please refer to FIG. 1 , which is the internal structure of the current rolling rotor type rotary compressor, which has a compression chamber 9 in a circular cylinder block 3, and the cylinder block 3 respectively An intake passage 7 and an exhaust passage 5 are provided, and respectively communicate with the compression chamber 9, and in order to prevent reverse flow of high pressure steam during operation, a selectively sealable exhaust valve 6 is provided in the exhaust passage 5, the cylinder The body 3 axis is collinear with the main shaft, in the compression chamber 9 on the main shaft An eccentric 2 that can be driven to rotate by an external motor (not shown) is disposed, and a steel thin-walled elastic piston sleeve 1 is sleeved outside the eccentric 2, and the eccentric 2 and the piston sleeve 1 are Called a toroidal rotor (referred to as the rotor below), the rotor side is tied to the steam The inner wall of the cylinder 3 is in close contact with each other, and the outer surface of the rotor forms a crescent-shaped compression chamber 9 with the inner wall of the cylinder block 3, and the cylinder block 3 between the intake passage 7 and the exhaust passage 5 is provided with an accommodation chamber G. The accommodating chamber G is provided with a sliding piece 4, one end of which is in contact with the outer wall of the piston sleeve 1, and the other end of which is coupled to a retractable elastic member 8, and the sliding piece 4 is freely accommodating in the accommodating chamber G. Reciprocating movement.

Please refer to the 2A~2D diagram, which is the operation process of the rotary rotor type rotary compressor. When the spindle rotates to drive the rotor to roll along the inner wall of the cylinder block 3, the position of the crescent-shaped compression chamber 9 changes accordingly. However, the total volume of the compression chamber 9 does not change, and under the action of the elastic member 8, one end of the slider 4 continues to be in close contact with the rotor, and the compression chamber 9 is partitioned to form two pressure chamber portions at the intake passage 7. The pressure chamber is called the intake chamber, and the pressure chamber at the exhaust passage 5 is called the exhaust chamber. In the reverse rolling direction of the rotor, the volume of the inlet chamber is gradually enlarged and the pressure is lowered (low pressure chamber). At the same time, at the same time, the volume of the exhaust chamber is gradually reduced to compress the internal gas. When the pressure in the exhaust chamber (high pressure chamber) rises to a certain extent, the exhaust valve 6 is opened due to the pressure difference. Gas, and in this way continuously cycle to achieve the suction-compression-exhaust working cycle process, and a cyclic process causes the compression chamber 9 to generate a considerable pressure difference between the low pressure chamber and the high pressure chamber during the compression process, so that the rotor is driven The motor requires a relatively large torque to lose , The power consumption is large.

As mentioned above, please refer to the figures 3A~3D, which are descriptions of the abnormal operation of the conventional rotary compressor. The extreme pressure difference generated by the compressor during the cycle causes the slide 4 to be laterally oriented. The force F is inclined, and the lateral force F is the product of the pressure difference and the surface area acting on the sliding plate 4, so the larger the pressure difference is, the larger the lateral force F is, and the lateral force F acts. When the slider 4 is used, the slider 4 located in the accommodating chamber G forms a resistance point of the lever due to the action of the moment, which tends to make the slider 4 unsmooth when reciprocating, and under long-term operation, The wear of the sliding plate 4 and the wall surface of the piston sleeve 1 is gradually increased due to long-term friction, so that the sporadic separation of the sliding plate 4 from the wall surface of the piston sleeve 1 creates a gap, which causes leakage loss and limits working life and efficiency. Increased, and due to the force of the elastic member 5, the separated sliding piece 4 is again in contact with the piston sleeve 1 to generate a noise, and the elastic element coupled with the sliding plate 4 is generated. The piece 8 also accelerates the elastic fatigue due to the torque generated by the lateral force F, so that the probability of separation is gradually increased to cause leakage loss and noise increase, which greatly reduces the working life and efficiency of the compressor.

In view of the above, in order to improve the above problems, the present invention discloses a multi-slide compressor and a segmented compression method, the technical feature of which is that the rotor generates segmented compression and segmented exhaust in a cycle of operation, which is effective. To reduce the required output work of the motor, the multi-slide type compressor comprises: a hollow cylinder block having a compression chamber, a plurality of intake passages, a plurality of exhaust passages and a plurality of accommodation chambers, and The intake passage, the accommodating chamber and the exhaust passage are arranged in a clockwise direction along the cylinder block, and the intake passage, the accommodating chamber and the exhaust passage are respectively connected to the outside of the compression chamber and the cylinder block, and the exhaust passage A valve member is disposed in the air passage for sealing the exhaust passage, and a piston sleeve is disposed in the compression chamber, and a part of the outer peripheral wall of the piston sleeve is in contact with the inner wall of the cylinder, and the piston sleeve is sleeved on the An eccentric wheel is externally connected, and one end of the eccentric wheel is coupled to a motor disposed outside the cylinder block, and a plurality of sliding plates are disposed in the accommodating chamber, and one end of the sliding piece is in contact with the outer wall of the piston sleeve, and is disposed at The sliding piece of the accommodating chamber can be on one axis Freely moving upwards, and at least one connecting rod member, which is a rod member disposed outside the cylinder block and not in contact with the cylinder block. One end of the connecting rod member is coupled to one end of the sliding piece, and the other end is coupled to the other sliding piece.
