The present invention relates to a refrigerator, and more specifically, to install a voltage generator and an electrode to generate a corona wind (corona wind) in the refrigerator condenser installation portion to improve the heat dissipation effect of the condenser by using the corona wind generated here It relates to a condenser heat dissipation aid of a refrigerator configured to be.

In general, as shown in FIG. 1 and FIG. 2, the refrigerator includes a compressor 2 installed in the lower machine room 1, a condenser 4 disposed on the rear wall 3 of the refrigerator, and a freezer compartment ( 5) The evaporator 6 is installed at the site. These are connected by a refrigerant tube, which is compressed to high pressure in the compressor (2), phase-converted to liquid refrigerant through heat exchange with the surroundings in the condenser (4), and evaporated at a predetermined temperature in a pressure reducer (not shown). To reduce the pressure. The refrigerant thus decompressed is evaporated while flowing inside the evaporator 6 to generate heat by absorbing heat from ambient air. The generated refrigerant is forcedly circulated by the blower 7 installed near the evaporator 6 and supplied to the freezing compartment and the refrigerating compartment to store and store food at an appropriate temperature in each storage compartment. (9) of FIG. 1 is a machine room cover, and (4 ') of FIG. 2 is an auxiliary condenser.

As shown in FIG. 2, the refrigerant in the refrigerator is compressed into a high pressure gas in the compressor 2, condensed into liquid refrigerant in the subcondenser 4 'and the condenser 4, and evaporated in the evaporator 6 through a capillary tube. Refrigeration and freezing are performed by cooling the surrounding space.

By the way, the refrigerant gas from the compressor 2 in such a refrigerator is not only high pressure but also a high temperature of about 70-90 ° C., and maintains about 45 ° C., which is much higher than room temperature or room temperature even in the condenser 4 having a heat exchange function. Effective heat dissipation of the compressor and condenser in such a high temperature state is closely related to the power consumption of the refrigerator. In the related art, a blower fan 8 is installed around the compressor to promote heat dissipation of the compressor. Heat dissipation was performed by convection. In other words, the heat around the compressor is typically radiated by a forced convection method driven by a blower fan and the heat of the condenser is radiated by a natural convection method.

However, since the heat dissipation of the compressor is blocked because the machine room in which the compressor is installed is closed by a cover, the heat dissipation effect is very low because the heat dissipation is performed only by natural convection in the condenser. In particular, since the refrigerator is disposed in close proximity to the wall of the home or office, there is a problem that the heat dissipation due to natural convection in the condenser is very low because the air flow in this part is not active.

The present invention is to solve the above problems, an object of the present invention is to provide a refrigerator that can effectively perform the heat radiation action of the condenser and the compressor.

Condenser heat dissipation auxiliary device of the refrigerator according to the present invention for achieving the above object, the corona wind generating means for generating a corona wind to assist the heat dissipation of the main body 10, the condenser 20 and the condenser And a voltage generating means for applying a voltage to the corona wind generating means, wherein the voltage generating means is a voltage generator 60 provided in the machine room 11 formed below the main body, and the corona wind generating means includes: A first electrode 40 and a second electrode 50 spaced apart from each other to generate a corona wind by applying a voltage generated from the voltage generator, and the condenser is installed on the rear wall 13 of the main body. The machine room is opened and closed by a cover 30 installed below the condenser, and the cover has a through hole 36 formed therein so that the corona wind generated by the corona wind generating means passes. It characterized.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the refrigerator according to the present invention.

3 is a perspective view of an embodiment of the present invention and FIG. 4 is a side cross-sectional view of FIG. As shown in the drawing, the refrigerator according to the present invention is roughly divided into a main body 10, a condenser 20 installed in the main body, and a first electrode 40 and a second generating a corona wind to assist heat dissipation of the condenser. And a voltage generator 60 that applies a voltage to the first electrode and the second electrode to generate a corona wind.

The machine room 11 is formed below the main body 10, and the compressor 12 is installed in this machine room 11.

The condenser 20 is installed on the rear wall 13 of the main body 10 above the machine room 11. The condenser 20 may be built in the rear wall 13 or attached to the outside thereof.

The machine room 11 is opened and closed by a cover 30. The cover 30 has a rear surface 31 formed to protrude outward from the rear wall 13 of the main body 10, and an upper surface 32, a lower surface 33, and a rear surface 31 formed above and below the rear surface 31, respectively. It has a left side 34 and a right side 35 respectively formed on both sides. The upper surface 32 and the lower surface 33 of the cover 30 is formed with a through hole 36 through which air flows. The through hole 36 may also be formed on the rear surface. The through hole 36 of the upper surface 32 is preferably formed such that the central portion is large and the peripheral portion is small. This is because the speed due to natural convection at the rear wall side of the refrigerator is fast around the center and slow around the periphery. It is because it is preferable.

On the other hand, the insulating material 14 is coated on the rear wall surface of the main body 10 inside the upper end of the cover 30 to prevent electricity generated from the voltage generator, which will be described later, from flowing to the refrigerator main body.

The first electrode 40 and the second electrode 50 are disposed side by side on the left and right sides 34 and 35 of the lid 30 while being spaced apart from each other by a predetermined interval. That is, the first electrode 40 and the second electrode 50 are formed in a bar shape so that one end is coupled to the left side 34 and the other end is coupled to the right side 35 so as to generate an appropriate corona wind. It is installed spaced apart a predetermined interval.

As shown in FIG. 5, the electrode fixing parts 41 and 51 are integrally formed on the left side 34 and the right side 35 of the cover 30, and the electrode fixing parts 41 and 51 are integrally formed. Insert grooves 42 and 52 into which the first and second electrodes 40 and 50 are inserted are formed. That is, both ends of the first and second electrodes 40 and 50 are inserted into the insertion grooves 42 and 52, respectively. At this time, it is preferable to combine through the auxiliary members 43, 53 in order to more firmly combine these.

The voltage generator 60 is installed at one side of the machine room 11. In this embodiment, it is installed in the lower body 10. The voltage generator 60 is for applying a high voltage between the first electrode 40 and the second electrode 50 and uses a known high voltage generator.

6 is a view for explaining the principle of corona wind generation. As shown in the drawing, when a voltage of several tens of kv is applied between the first electrode 40 and the second electrode 50 in the high voltage generator 60, the electric field between the electric charges in the air becomes remarkably uneven. The air on the surface is ionized and discharge occurs to generate corona or ionic wind. In more detail, in the high voltage generator 60, a positive potential is applied to the first electrode 40 to generate a potential difference of several tens of kv or more between the first electrode 40 and the second electrode 50. When the negative potential is applied to 50, an electric field line is formed between the first electrode 40 and the second electrode 50, and at the same time, corona discharge occurs using air as an insulating layer. At this time, the air around the first electrode 40 causes ionization by a large amount of electrons emitted from the first electrode 40 to move toward the second electrode 50 along the electric force line. The air flow generated in this way is called corona wind or ion wind. In the present embodiment, a voltage is applied to generate corona wind from below to upward, and the generated corona wind passes around the condenser 20 to help the heat dissipation, that is, the cooling action.

7 shows another embodiment of the present invention. In the present embodiment, a plurality of needle-like protrusions 70 are formed on the first electrode 40. Therefore, the corona discharge is easily generated to help the generation of corona wind.

Referring to the operation of the condenser heat dissipation auxiliary device of the refrigerator according to the present invention configured as described above are as follows.

First, in the high voltage generator 60, a positive potential is applied to the first electrode 40 and a negative potential is applied to the second electrode 50 so that a potential difference of several tens of kv or more occurs between the first electrode 40 and the second electrode 50. By applying an electric field line between the first electrode 40 and the second electrode 50, corona discharge is generated by using air as an insulating layer. At this time, the air around the first electrode 40 causes ionization by a large amount of electrons emitted from the first electrode 40, and moves toward the second electrode 50 along the electric force line, thereby generating a corona wind. Corona wind generated in this way passes through the through hole 36 of the upper surface 32 of the cover 30 and passes around the condenser above it to help the heat dissipation of the condenser. This corona flow rate is faster than the flow rate due to natural convection around the condenser, effectively cooling the condenser.

As described in detail above, the condenser heat dissipation auxiliary device of the refrigerator according to the present invention, by installing a high voltage generator and the electrode inside the machine room and forming a through hole in the machine room cover, by applying a high voltage to generate a corona wind between the electrodes and this corona The air is configured to pass around the condenser through the opening of the cover to force the convection of air around the condenser to help the condenser heat dissipation. Therefore, the thermal shear capacity of the condenser is remarkably improved as compared to the case of relying only on natural convection.
