Problems solved by technology

[0006] In the hermetic compressor of the prior art, although the resonant cavity 37 on the cylinder 31 can reduce the noise of the compressor, it increases the "dead volume" of the cylinder, reduces the suction and discharge volume of the cylinder, and reduces the s efficiency
If there is no resonance cavity on the cylinder 31, the noise generated by the compressor will increase

Embodiment Construction

[0045] Hereinafter, the resonant cavity structure of a hermetic compressor of the present invention will be described in detail with reference to the accompanying drawings and embodiments:

[0046] Parts in the present invention are identical with those of the prior art and adopt the same reference numerals.

[0047] Such as Figure 3-8 As shown, the resonant cavity structure of the hermetic compressor of the present invention, said hermetic compressor includes a housing 1, a motor 20 is installed on the inner upper side of the housing 1, and a certain distance is installed on the lower side of the motor 20 There is a compressor assembly 30 .

[0048] The motor 20 is press-fitted and fixed on the inner circumferential surface of the cylinder 11. The motor 20 is composed of a stator 21, a rotor 22, and a rotating crankshaft 23 that is press-fitted and fixed at the center of the rotor 22 and transmits rotational force.

[0049] Compressor assembly 30 includes upper bearing 32 ...

Abstract

The invention discloses a resonant cavity structure of a closed compressor. The structure comprises a cylinder and a resonant cavity formed on the cylinder; two ends of the resonant cavity are provided with a groove, one end of the groove is communicated with an exhaust port of the cylinder, and the other end of the groove is communicated to the outside of the cylinder; and a slide block is arranged in the groove, a circular baffle plate is arranged in the resonant cavity below the slide block, a spring is arranged below the baffle plate, and the inner circular wall of the resonant cavity between the slide block and the baffle plate is provided with at least two symmetrical limiting lug bosses. Because the two sides of the resonant cavity are provided with the groove and the slide block is arranged in the groove, when the cylinder sucks and exhausts air, the structure ensures the silencing effect of the resonant cavity, can increase the displacement of the cylinder, and improves the efficiency of the compressor.

Description

technical field [0001] The invention belongs to a hermetic compressor, and in particular relates to a slot at both ends of a resonant cavity, and a slide block is installed in the slot to increase the discharge volume of the cylinder. The sound-absorbing effect of the resonance chamber can increase the discharge volume of the cylinder and improve the efficiency of the compressor. It is a resonance chamber structure of a hermetic compressor. Background technique [0002] Such as figure 1 , 2 As shown, the hermetic compressor in the prior art includes a housing 1, a motor 20 is installed on the upper side of the housing 1, and a compressor assembly 30 is installed on the lower side of the motor 20 at a certain distance. The casing 1 is composed of a hollow circular cylinder 11 , an upper cover 12 and a lower cover 13 and the like. The motor 20 is press-fitted and fixed on the inner peripheral surface of the cylinder 11, and it is composed of a stator 21, a rotor 22, and a r...
