Embodiment 1

[0040] Such as Figure 1 to Figure 10 As shown, this embodiment provides an exhaust valve assembly 1, the exhaust valve assembly 1 includes a valve seat 11, a valve plate 12 and an auxiliary opening and closing mechanism, the valve seat 11 is provided with an exhaust port 112, The valve plate 12 has a free end and a fixed end, the fixed end is fixed on the valve seat 11, and the free end is covered on the exhaust port 112; the auxiliary opening and closing mechanism is used for An auxiliary force is applied to the free end, and the direction of the auxiliary force is directed from the exhaust port 112 to the free end.

[0041] Such as figure 1 and Figure 5 As shown, the auxiliary opening and closing mechanism provided in this embodiment includes a valve seat 11, a valve plate 12 and an auxiliary opening and closing mechanism. The auxiliary force at the free end, when the compression chamber needs to be changed, the auxiliary force exerted by the auxiliary opening and closi...

Embodiment 2

[0045] Such as Figure 1 to Figure 3As shown, the exhaust valve assembly 1 provided in this embodiment includes a valve seat 11, a valve plate 12 and an auxiliary opening and closing mechanism, the valve seat 11 is provided with an exhaust port 112, and the valve plate 12 has a free end and a fixed end, the fixed end is fixed on the valve seat 11 , and the free end is covered on the exhaust port 112 . The auxiliary opening and closing mechanism includes an electromagnetic device 14, and the electromagnetic device 14 is arranged corresponding to the free end to provide a magnetic attraction force to the free end, and overcome the elastic force of the valve plate 12 through the magnetic attraction force, but does not move the valve The free end of the sheet 12 adsorbs to open the exhaust port 112. At this time, the compression chamber does not need to overcome the elastic force of the valve sheet 12 during exhausting, which can reduce the pressure in the compression chamber duri...

Embodiment 3

[0058] Such as Figure 4 to Figure 9 As shown, this embodiment provides an exhaust valve assembly 1, the exhaust valve assembly 1 includes a valve seat 11, a valve plate 12 and an auxiliary opening and closing mechanism; the auxiliary opening and closing mechanism includes a driving member and a limiting member 16. The limiting member 16 includes a connected first rod portion 161 and a second rod portion 162, the cross-sectional size of the first rod portion 161 is larger than the cross-sectional size of the second rod portion 162; the valve seat 11 is provided with a limiting hole 116, the driving member is connected with one end of the first rod part 161, and the other end of the first rod part 161 is connected with the second rod part 162, and the second rod part The other end of 162 is inserted into the limiting hole 116, and the driving member is used to drive the limiting member 16 to move along the limiting hole 116 on the lower side of the valve plate 12; the second ro...

Abstract

The invention relates to the technical field of household appliances, in particular to an exhaust valve assembly, a compressor and refrigeration equipment. The exhaust valve assembly provided by the embodiment of the invention comprises a valve seat, a valve plate and an auxiliary opening and closing mechanism; the auxiliary opening and closing mechanism can provide an auxiliary force for the freeend of the valve plate, auxiliary force is directed from an exhaust port to the free end of the valve plate, the auxiliary opening and closing mechanism can offset the elastic force of the valve plate with the auxiliary force of the free end of the valve plate, the elastic force of the valve plate does not need to be overcome when a compression chamber exhausts air, thus the pressure in the compression chamber is reduced when air is exhausted, the compression loss is reduced and the energy efficiency is improved; and in addition, when the compression chamber needs capacity change, the auxiliary force exerted by the auxiliary opening and closing mechanism drives the free end of the valve plate to open the exhaust port, the compression chamber communicates with a shell, a capacity chamber can not complete the compression process, and the capacity change is realized. The capacity change of the compressor can be realized without introducing pressure, and the energy efficiency of the compressor can be improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an exhaust valve assembly, a compressor and refrigeration equipment. Background technique [0002] The traditional piston-type compression chamber usually adopts the bypass structure of the control valve to realize the variable capacity when realizing the variable capacity. The pressure after compression or the intermediate pressure after compression, this part of the gas does not participate in the refrigeration cycle, which affects the energy efficiency of the compressor. Contents of the invention [0003] (1) The technical problem to be solved by the present invention is: the current piston compressor needs to introduce bypass pressure when changing capacity, the bypass pressure introduced is high pressure or intermediate pressure after compression, this part of pressure does not participate in refrigeration cycle, affects Compressor energy efficiency. [0004...
