The vibration damping structure of refrigerator

Technical field

The present invention relates to a kind of parts of refrigerator, particularly relate to a kind of vibration damping structure of refrigerator.

Background technique

Well-known refrigerator is a kind of device that is used for storing food under low-temperature condition, as Fig. 1, shown in 2, existing common refrigerator has shell 1 and inner casing 2, inner casing 2 internal upper parts are refrigerating chamber U, the bottom is cold storage room L, between shell 1 and the inner casing 2 vaporizer 3 is installed, one side of vaporizer 3 is equipped with circulating fan 4, circulating fan 4 is transported to refrigerating chamber U and cold storage room L with the cold air that vaporizer 3 produces, bottom one side of cold storage room L is provided with the machine room, compressor 50 is installed in the machine room, compressor 50 will be compressed into the High Temperature High Pressure gaseous coolant from the high-temperature low-pressure gaseous coolant that vaporizer 3 flows into, the exhaust port of compressor 50 is connected with condenser 52, and condenser 52 is condensed into the high-pressure liquid refrigerant with the High Temperature High Pressure gaseous coolant that compressor 50 produces; The high-pressure liquid refrigerant that condenser 52 produces is by the decompression of capillary tube (not shown), and post-decompression liquid refrigerants is sent back to vaporizer 3, and the heat that absorbs surrounding atmosphere produces cold air.

In addition, in described machine room, compressor 50 is arranged side by side with condenser 52, and interconnects by cooling duct 51, is provided with drip trap 53 below the condenser 52, and the effect of drip trap 53 is to collect the condensed waters that condenser 52 surfaces form; For the radiating efficiency of the refrigerant pipe 52a that improves condenser 52, several heat-removal bars 52b has been installed on the refrigerant pipe 52a, a side of condenser 52 also is provided with blowing fan 54, with the radiating efficiency of further raising condenser 52.

From above as can be known, in the compressor 50 of existing common refrigerator, be directly the high-temperature low-pressure refrigerant to be compressed into the liquid refrigerant of High Temperature High Pressure, compressor 50 can vibrate in compression process, the vibration meeting of compressor so pass near condenser 52 and other parts, its result not only can produce bigger noise, and the long-time vibration that continues can influence the refrigerator stability of structure.

In order to prevent that the vibration that compressor 50 produces is delivered to refrigerator integral body by condenser 52, is fixed on the drip trap 53 with the lower end of screw with above-mentioned heat-removal bar 52b.

Though said method can reduce the vibration that passes over from compressor 50 to a certain extent, but the drip trap 53 that heat-removal bar 52b that metallic material is made and plastic materials are made is connected and fixed the problem that still can not thoroughly solve vibration transfer by screw, and the long-time vibration that continues still can influence the refrigerator stability of structure.

Summary of the invention

Technical problem to be solved by this invention is, overcoming the parts transmission towards periphery of existing common refrigerator vibration of compressor influences the shortcoming of refrigerator structure stability, provides a kind of vibration that prevents that compressor from producing to be delivered to the vibration damping equipment of the refrigerator of refrigerator integral body by condenser.

In order to solve the problems of the technologies described above, the technological scheme that the vibration damping structure of refrigerator of the present invention adopts is: comprising: compressor, vibration damper, condenser, refrigerant pipe, heat-removal bar, drip trap and shock absorbing material; Described vibration damper is installed between each lower margin of compressor and the bottom surface, refrigerator machine room; Described heat-removal bar is installed on the refrigerant pipe of condenser, and the underpart of heat-removal bar is fixed on the sidewall of drip trap, between the underpart of heat-removal bar and the sidewall of drip trap shock absorbing material is installed.

The underpart of described heat-removal bar respectively has a through hole, be inserted with the rubber-like shock absorbing material in the through hole, shock absorbing material is cylindrical, its waist has groove, after shock absorbing material inserts through hole, groove just in time is positioned at through hole, and the other parts of shock absorbing material are clipped in the middle the underpart of heat-removal bar; Pass shock absorbing material by screw, the underpart of heat-removal bar is fixed on the sidewall of drip trap.

Described shock absorbing material is a rubber material.

The invention has the beneficial effects as follows: simple in structure, the damping efficiency height had both reduced noise, had guaranteed refrigerator stability of structure under long-term service condition continuously again.

Embodiment

Be described in further detail below in conjunction with the vibration damping equipment of the drawings and specific embodiments refrigerator of the present invention:

Use the refrigerator of the vibration damping equipment of refrigerator of the present invention to have shell 1 and inner casing 2, inner casing 2 internal upper parts are refrigerating chamber U, the bottom is cold storage room L, between shell 1 and the inner casing 2 vaporizer 3 is installed, one side of vaporizer 3 is equipped with circulating fan 4, circulating fan 4 is transported to refrigerating chamber U and cold storage room L with the cold air that vaporizer 3 produces, bottom one side of cold storage room L is provided with the machine room, compressor 50 is installed in the machine room, compressor 50 will be compressed into the High Temperature High Pressure gaseous coolant from the high-temperature low-pressure gaseous coolant that vaporizer 3 flows into, the exhaust port of compressor 50 is connected with condenser 52, and condenser 52 is condensed into the high-pressure liquid refrigerant with the High Temperature High Pressure gaseous coolant that compressor 50 produces; The high-pressure liquid refrigerant that condenser 52 produces is by the decompression of capillary tube (not shown), and post-decompression liquid refrigerants is sent back to vaporizer 3, and the heat that absorbs surrounding atmosphere produces cold air.

Shown in Fig. 3,4,5, compressor 50 is installed in the machine room side by side with condenser 52, is linked to each other by refrigerant conduit 51 between the two; In order to improve condenser 52 radiating efficiencys, on the refrigerant pipe 52a of condenser 52 some heat-
