Description
Technical field
The present invention relates to a kind of reduction noise structure of refrigerator, more precisely by changing capillary location, the invention of the reduction noise configuration aspects of the refrigerator of the noise of reduction medium fluid and refrigerator integral body.
Background technology
With reference to the accompanying drawings, the refrigerator to prior art describes.
For refrigeration and freezing required cold air are provided, general refrigerator has adopted freeze cycle as shown in Figure 1.
As shown in the figure, the freeze cycle 101 of above-mentioned refrigerator includes compressor 103, condenser 111, capillary 200 and evaporimeter 119 substantially.Above-mentioned compressor 103 is used for the medium of compression by the low-temp low-pressure of air intake duct (suction pipe) 120 inflows; Above-mentioned condenser 111 is by after the heat heat radiation of radiating tube 105,107,109 with high-temperature medium, and the medium of high temperature is liquefied; Above-mentioned capillary 200 will become the medium of low-pressure state through the media expansion that drier (dryer) 113 flows into; Above-mentioned evaporimeter 119 utilizes the medium that flows into to reservoir (accumulator) 117 from above-mentioned capillary 200, from low heat absorption heat.
Simple declaration has the freeze cycle 101 of the refrigerator of said structure, then at first in above-mentioned compressor 103 media such as freon gas is compressed into high-temperature high-pressure state, is supplied to auxiliary heat dissipation pipe 105.At this moment above-mentioned auxiliary heat dissipation pipe 105 is arranged on the bottom of refrigerator usually, can utilize about 75 ℃ high temperature from above-mentioned compressor 103, and the water that will produce in above-mentioned evaporimeter 119 defrosting backs evaporates.In said process, because being defrosted, the part heat in the high-temperature medium sponges when water afterwards evaporates, so bring favourable additional effect to a certain extent.
Medium through above-mentioned auxiliary heat dissipation pipe 105 will be through superheater tube (hot pipe) 107, above-mentioned heat pipe 107 operated by rotary motion are at the refrigerator reveal, because refrigerator temperature inside and outside temperature difference produce the phenomenon of dew, at this moment also need to obtain a certain amount of heat when preventing to open and close refrigerator from above-mentioned medium in order to evaporate above-mentioned dew.
As mentioned above, again through plate radiating tube 109 and the condenser 111 sufficiently cooled liquid conditions that change into later, be fed to above-mentioned drier 113 via the medium of above-mentioned radiating tube 107 then.The effect of above-mentioned drier 113 is to remove fully and be cooled to moisture residual the medium of low-temperature condition with flowing in above-mentioned condenser 111 processes from the condition of high temperature.If when directly being supplied to above-mentioned evaporimeter 119 to carry out heat exchange in the residual medium that moisture arranged,, will reduce cooling effectiveness greatly because the heat exchange coefficient of medium and water is different.
The medium of the cryogenic high pressure that above-mentioned drier 113 moisture of process are removed flow in the above-mentioned capillary 200.In above-mentioned capillary 200, medium becomes low pressure from the rapid adiabatic expansion of high pressure, converts the low-temp low-pressure state to, makes temperature be declined to become-30 ℃.
The liquid medium that converts the low-temp low-pressure state by above-mentioned capillary 200 to sharply gasifies at above-mentioned evaporimeter 119, obtains heat from ambient air, produces the cold air that is used for to refrigerating chamber and refrigerating chamber supply.At this moment the liquid medium that is not fully gasified at above-mentioned evaporimeter 119 separates, and flow in the above-mentioned reservoir 117, makes to 103 supplies of above-mentioned compressor liquid medium.
Fig. 2 is the part sectional drawing of the structure of capillary and air intake duct.
As shown in the figure, for the adiabatic expansion of medium, above-mentioned capillary 200 has adopted very thin very thin tubular structure, has adopted the structure that it is curled in order to dwindle the space that capillary occupies, and above-mentioned curling structure forms curled portion 210.
Prolong the heat exchange department 220 that forms from above-mentioned curled portion 210 in addition and be installed near above-mentioned air intake duct 120 places, this is for the evaporating temperature of obtaining medium in the freeze cycle and reduces condensation temperature.
That is to say, make and carry out heat exchange mutually between the medium in the media and above-mentioned air intake duct 120 in the above-mentioned capillary 200 that the low-temperature evaporation medium by above-mentioned air intake duct 120 makes the cooling medium of above-mentioned capillary 200 turn cold; On the contrary, the high temperature cooling medium by above-mentioned capillary 200 makes the evaporative medium heating of above-mentioned air intake duct 120, evaporates fully.
But prior art said structure in, in the operation process of compressor, the vibration of compressor will pass to curled portion capillaceous through air intake duct, make capillary produce vibration, become the main noise of refrigerator.
This shows that above-mentioned existing refrigerator refrigeration loop structure still has many defectives, and the assistant officer waits to be improved.
Because the defective that above-mentioned existing refrigerator refrigeration loop structure exists, the design people is based on being engaged in this type of product design manufacturing for many years, amassing has abundant practical experience and professional knowledge, actively studied innovation, in the hope of founding a kind of reduction noise structure of improving the refrigerator of molding structure, can improve the general molding structure of existing conventional refrigerator refrigeration loop structure on the market, make it have more competitiveness.Through constantly research, design, and after studying sample and improvement repeatedly, create the present invention who has practical value finally.
Summary of the invention
