Method used

Although the effect of heat insulation and noise reduction is good, it is difficult to realize that the exhaust noise reduction structure of plastic material is manufactured according to conventional methods, and the present invention can be refitted according to traditional cylinder head 1, that is, utilize cylinder head The inner cavity part of 1 is used as the sound-absorbing chamber 12, and the inner liner 11 is set to be similar to the shape of the surface layer of the sound-absorbing cha...

Abstract

The invention discloses an exhausting and sound deadening structure of a refrigerator compressor. The exhausting and sound deadening structure comprises a cylinder cover and a valve plate, wherein the cylinder cover is provided with a sound deadening cavity; the valve plate is connected with the end face of the sound deadening cavity; and a heat insulating layer is arranged on the inner surface of the sound deadening cavity. In the invention, the heat insulating layer is arranged in the sound deadening cavity to ensure that high-temperature high-pressure gas exhausted from a gas vent of the compressor is depressurized and silenced by the sound deadening cavity, the heat of the gas per se is blocked by the heat insulating layer and cannot be dissipated in a shell of the compressor through the cylinder cover or the valve plate and most of heat can only be exhausted via an exhaust path; and therefore, the complete machine shell temperature of the compressor can be reduced and the efficiency of the compressor is increased. The exhausting and sound deadening structure disclosed by the invention is suitable for serving as an exhaust system structure of the refrigerator compressor.

Example Embodiment

[0013] Reference Figure 1 ~ Figure 2 , Refrigerator compressor exhaust muffler structure, which includes a cylinder head 1 with a muffler cavity 12 and a valve plate 2 connected to the end surface of the muffler cavity 12, the inner surface of the muffler cavity 12 is provided with a heat insulation layer.

[0014] Further as a preferred embodiment, the muffler cavity 12 is provided with an inner liner 11 attached to its inner surface, and the inner liner 11 is a polymer material member with poor thermal conductivity, thereby forming the heat insulation Floor. Of course, in actual assembly, more suitable spacers or gaskets can be added according to the air tightness, such as figure 2 As shown, a gasket 3 and a spacer 4 are installed between the valve plate 2 and the inner liner 11, and an intake valve plate 5 and a valve plate gasket 6 are installed between the valve plate 2 and the cylinder seat to be connected. These are the structures commonly used in the suction and discharge parts of conventional refrigerator compressors.

[0015] Further as a preferred embodiment, the inner bushing 11 is a high temperature resistant plastic member. The inner liner 11 is made of a polymer material with poor thermal conductivity, and a high-temperature resistant plastic material is preferred.

[0016] Although the heat insulation and noise reduction effect is good, it is difficult to manufacture the plastic exhaust noise reduction structure according to the conventional method, and the present invention can be modified according to the traditional cylinder head 1, that is, using the inner cylinder head 1. The cavity part is used as the muffler cavity 12, the inner liner 11 is set to be similar to the surface shape of the muffler cavity 12, and the inner liner 11 can be placed in the muffler cavity 12 during use. After the inner liner 11 is installed in the cylinder head 1, the gasket 3 and the valve disc 2 are installed to complete the assembly work of the present invention. The inner liner 11 itself is attached to the surface of the muffler cavity 12, so a cavity is also formed for exhaust muffler, and its heat insulation performance can effectively reduce the internal temperature of the shell.

[0017] The above is a detailed description of the preferred embodiments of the present invention, but the invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. These equivalent modifications or replacements are all included in the scope defined by the claims of this application.
