Vibration absorbing structure of refrigerator

The present invention relates to a vibration reduction structure of a refrigerator, and more particularly, to a vibration reduction structure of a refrigerator in which a lower end of the condenser is fixed to a drain pan by a dustproof member in order to prevent the vibration generated from the compressor from being transmitted to the entire refrigerator through the condenser. It is about.

In general, a refrigerator is a device for storing food in a fresh state for a long time by cooling the food by providing a cold air using a refrigeration cycle or preventing corruption.

1 is a side cross-sectional view showing the structure of a refrigerator according to the prior art, Figure 2 is a view showing the configuration of the machine room of the refrigerator according to the prior art.

In the conventional refrigerator, the outer case 1 and inner case 2 forming the exterior as shown in FIG. 1 are partitioned into a freezer compartment U and a refrigerating compartment L at upper and lower sides thereof, and the outer case 1 An evaporator 3 is embedded between the inner case 2 and a circulation fan 4 is mounted at one side of the evaporator 3 to cool the air around the evaporator 3 in the freezer compartment and the refrigerating compartment. To the compressor (10) and the discharge port of the compressor (10) to form a high-temperature, high-pressure gas refrigerant by compressing the low-temperature low-pressure gas refrigerant from the evaporator (3) is formed in the machine room below the refrigerating chamber (L) Connected condenser 12 is installed to condense the high-temperature, high-pressure gas refrigerant by the compressor 10 in a high-pressure liquid state.

Then, the high pressure liquid refrigerant passing through the condenser 12 is decompressed while passing through a capillary tube (not shown), and the liquid refrigerant decompressed by the capillary tube (not shown) flows back into the evaporator 3 and It absorbs heat and evaporates to produce cold air.

Here, the compressor room 10 and the condenser 12 are installed side by side in the machine room, but are connected to each other by the refrigerant pipe 11, the condenser 12 is condensed on the surface of the evaporator (3) A drain pan 13 is installed to collect condensed water, and a plurality of fins 12b are mounted to the refrigerant pipe 12a in order to increase heat dissipation efficiency in the refrigerant pipe 12a of the condenser 12. In order to increase the heat dissipation efficiency of the condenser 12, a blower fan 14 for blowing outside air to the condenser 12 through which a high temperature refrigerant passes is installed at one side of the condenser 12.

However, in the conventional refrigerator, vibration occurs because the compressor compresses the refrigerant introduced from the evaporator in order to liquefy the refrigerant at a relatively high temperature, and the vibration generated in the compressor is transmitted to a condenser located in the vicinity of the noise to generate noise. Not only does it occur, there is a problem of structural instability due to continuous vibration during long-term use.

Thus, in order to compensate for this in the prior art, the lower part of the fin may be fixed to one side of the drain pan to prevent the vibration generated from the compressor from being transmitted to the entire refrigerator through the condenser.

However, since the lower end of the condenser is directly fixed to one side of the drain pan by a screw, the vibration transmitted from the compressor is partially attenuated. However, the pin and the drain pan made of plastic are in direct contact with each other so that the condenser lower part and the drain are in use for a long time. There is a problem that there is a gap between the fans to generate noise as well as vibration is transmitted to the whole product structurally unstable.

The present invention has been made to solve the above problems of the prior art, the condenser is fixed to the drain pan so that the vibration generated from the compressor of the refrigerator is not transmitted to the entire refrigerator through the condenser, even if the product is used for a long time The purpose of the present invention is to provide a vibration reducing structure of the condenser refrigerator that can reduce noise and solve structural instability of the product by fixing the condenser to the drain pan so that there is no gap between the drain pans.

Vibration reduction structure of the refrigerator according to the present invention for solving the above problems is a compressor for compressing the refrigerant passing through the evaporator in the machine room formed under the refrigerating chamber, and a condenser for condensing the high-temperature high-pressure gas refrigerant flowing out of the compressor And a drain pan installed under the condenser to collect condensed water condensed from the evaporator side and collecting the condensate, wherein the vibration generated by the compressor is prevented from being transmitted to the entire refrigerator through the condenser. A dustproof member is installed between the drain pans.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a view showing the machine room configuration of the refrigerator according to the present invention, Figure 4 is a cross-sectional view taken along the line A-A of Figure 3, Figure 5 is a perspective view showing a condenser fin and a dustproof member according to the present invention.

In the refrigerator according to the present invention, the outer case and the inner case forming the exterior are divided into upper and lower sides into a freezer compartment and a refrigerating compartment, an evaporator is built in between the outer case and the inner case, and a circulation fan is mounted at one side of the evaporator. The air cooled by the evaporator is supplied to the freezer compartment and the refrigerating compartment, and a machine room is formed at the lower side of the refrigerating compartment to inhale and compress the low-temperature low-pressure gas refrigerant introduced from the evaporator to increase the pressure of the refrigerant to liquefy the refrigerant at a relatively high temperature. A condenser is installed to liquefy the gas refrigerant of high temperature and high pressure passing through the compressor with water or air at room temperature to become a liquid refrigerant of medium temperature and high pressure.

The liquid refrigerant passing through the condenser is decompressed to be easily evaporated at a relatively high temperature while passing through a capillary tube having a narrower diameter than that of the other portion, and the low temperature and low pressure liquid refrigerant passing through the capillary tube flows into the evaporator again. As it passes through the evaporator, it exchanges heat with the surrounding fluid, producing cold air.

In particular, the configuration of the machine room in detail as shown in FIG. 3, the compressor 50 and the condenser 52 are installed side by side by the refrigerant pipe 51, the condenser 52 is a high temperature to increase the heat dissipation effect Fins 52b and 52c are attached to the refrigerant pipe 52a through which the gas refrigerant flows, and the heat transfer area is widened. A blower fan 54 is installed at one side of the refrigerant pipe 52a to blow external air.

In addition, the lower side of the compressor 50 is supported by the dampers 50a and 50b in order to reduce the vibration generated from the compressor 50, and the vibration generated from the compressor 50 causes the condenser 52 to move. The lower end of the condenser 52 is fixed to the drain pan 53 by the dustproof member 55 so as not to contact the drain pan 53 in order to prevent the refrigerator from being transferred to the entire refrigerator.

The dustproof member 53 is installed at a lower end of a plurality of fins 53c attached to the refrigerant pipe 52a of the condenser 52, and the dustproof member 55 is shown in FIGS. 4 and 5. ) Is installed in the pin 52c has a lower end longer than the other pins (52b), the hole (H) is formed in the center of the lower end of the pin (52c), the dustproof member 55 is the pin (52c) The fitting hole 55h is formed on the circumferential surface of the hole H so as not to be fitted out.

Therefore, when the fitting hole 55h of the dustproof member 55 is restrained and seated in the hole H formed at the lower end of the fin 52c of the condenser 52, the center of the dustproof member 55 is the drain pan. The lower end of the condenser 52 is fixed without being directly contacted with the drain pan 53 by being fixed with a screw 56 on one side of the 53.

Here, the vibration isolator 55 is made of a rubber material having a predetermined elastic force to absorb the vibration transmitted from the condenser 52.

Looking at the operation of the present invention configured as described above are as follows.

When the refrigerator is driven, the compressor is operated and the refrigerant, which has been changed into a high temperature and high pressure vapor state compressed by the compressor, is sucked into the condenser, and the condenser releases heat to change the refrigerant into a liquid state at room temperature and high pressure, and condenses by the condenser. As the refrigerant passes through the capillary tube, some of the refrigerant is submerged to form a mixture of liquid and gas.

Then, the refrigerant sucked into the evaporator is completely vaporized to take the heat of the surroundings to cool the surroundings, and the air cooled by the evaporator is provided to the freezer compartment and the refrigerating compartment by the circulation fan to maintain the inside of the refrigerator at a low temperature. .

Here, the compressor 50 is a vibration occurs because it compresses the refrigerant flowing from the evaporator (not shown) to a high-temperature, high-pressure steam state, the vibration of the compressor 50 is a damper (50a) attached to the compressor 50 side Partially absorbed by the 50b, the vibration transmitted from the compressor 50 to the condenser 52 is attenuated by the condenser 52 being fixed to the drain pan 53.

In addition, since the rubber dustproof member 55 is fixed between the lower end of the condenser 52 and the drain pan 53, the vibration transmitted from the compressor 50 to the condenser 52 is not only partially absorbed but also vibrated. As a result, noise generated between the lower end of the condenser 52 and the drain pan 53 can be reduced.

Therefore, since the vibration generated in the compressor is attenuated while passing through the condenser, it is not transmitted to the entire refrigerator, so it is structurally stable even in long-term use and also has a great noise reduction effect.

The vibration reducing structure of the refrigerator according to the present invention configured as described above occurs between the condenser lower part and the drain pan due to the vibration transmitted from the compressor to the condenser by fixing the lower part of the condenser in close contact with the drain pan using a rubber dustproof member. In addition to reducing the noise, it is possible to achieve structural stability of the entire refrigerator by attenuating the vibration transmitted from the compressor to the entire refrigerator through the condenser on the condenser side.
