The present invention relates to a refrigerator, and more particularly, to a refrigerator in which heat dissipation of a condenser can be more effectively performed.

In a conventional refrigerator, a machine room is provided at the rear of a refrigerator main body, a compressor for compressing a refrigerant in the machine room, a condenser connected to the compressor to condense the refrigerant, and provided on one side of the condenser, hot heat generated from the condenser. There was provided a blowing fan that radiates heat to the outside.

The condenser is connected to a capillary tube for expanding the refrigerant under reduced pressure, and the capillary tube is again connected to an evaporator provided behind the storage compartment of the main body. Therefore, the refrigerant cycle of the refrigerator is to supply the cold air to the storage compartment through the compression, condensation, expansion, evaporation of the four stages to enable the freezing or refrigeration of the storage.

In particular, the condenser serves to change the refrigerant of the high-temperature, high-pressure gas phase into the liquid phase. At this time, the liquefaction of the refrigerant occurs by heat exchange between the external air and the refrigerant in the condenser, and the heat exchange occurs. The blowing fan is provided by supplying air toward the condenser.

By the way, when the conventional blowing fan rotates to supply air in the condenser direction, there is a problem in that the air moving direction is not concentrated in the condenser direction but is dispersed outside the condenser.

An object of the present invention is to provide a refrigerator that can improve the heat dissipation performance of the condenser by allowing the flow of air blown to the condenser by a blower fan to be concentrated to the condenser.

The present invention for achieving the above object is a condenser,

A blowing fan spaced apart from the condenser and blowing air to the condenser;

A fan case rotatably supported by the blower fan and provided with a blower formed in the condenser direction;

The refrigerator is provided around the tuyeres to prevent the air from being blown and to provide a refrigerator guide member to guide the condenser to the condenser.

In addition, the tuyere is provided in a circular shape and the diameter is larger than the diameter of the blowing fan, the blowing guide member extends outward from the surface of the fan case and provided in the form of continuously surrounding the periphery of the tuyere It is characterized by.

In addition, the blowing guide member is characterized in that it is provided in an annular shape.

In addition, the blowing guide member is characterized in that extending in the condenser direction from the surface of the fan case.

In addition, the inner circumferential surface of the tuyere and the air blowing guide member is connected to prevent the loss of air flow.

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

As shown in FIG. 1, the refrigerator according to the present invention is placed in a main body 10 forming its appearance, a machine room 13 provided below the main body 10, and a lower part of the machine room 13. The base plate 15 to be included is included.

On the upper surface of the base plate 15, a compressor 17 for compressing the refrigerant, a condenser 20 for condensing the refrigerant, a refrigerant pipe 18 serving as a moving passage of the refrigerant, and one side of the condenser 20 It is provided with a blower 25 for blowing air to the condenser 20 to release the heat of the condenser 20.

Here, the blower 25 is connected to the blower fan 27 and the fan case 30 surrounding the blower fan 27 and provided in the form of a plate, and the blower fan 27 to the blower fan ( And a fan motor 33 for rotating 27.

Here, the fan case 30 is provided with a blower 31 for guiding the flow of air blown from the blower fan 27 toward the condenser 20, and the air blower is provided around the blower hole 31. A blowing guide member 32 is provided to guide the flow of air to the condenser 20 in a concentrated manner.

As shown in FIG. 2, the fan motor 33 is provided at the rear of the fan case 30, and the fan motor 33 and the fan case 30 are connected by a connection part 34.

The fan case 30 is formed with the blower 31, and the blower 31 is preferably configured to have a circular shape for smooth air blowing, and the blower guide member 32 surrounds the air outlet 31. It is appropriate that it is provided in the form of a ring wall encircling continuously.

Here, the air blowing guide member 32 is extended to the outside of the fan case 30, the extending direction is preferably provided to face the condenser (see Fig. 1, 20).

The blower fan 27 includes a hub 27a at a central portion thereof, and blades 27b extending in a circumferential direction from the outer circumferential surface of the hub 27a and spaced at regular intervals. Between the fan motor 33 is provided a rotation shaft 27c for transmitting the rotational power of the fan motor 33 to the blowing fan 27.

Here, in order to smoothly blow the blower fan 31, the inner diameter of the blower hole 31 is preferably larger than the outer diameter of the blower fan 27, and the blower guide member 32 has a concentration of blower air. In order to prevent the loss of air flow, it is preferable that the inner circumferential surface of the blower 31 and the inner circumferential surface of the blower guide member 32 are connected to each other. .

Hereinafter, with reference to the accompanying drawings will be described the operation and differences between the prior art and the present invention will be described with the same reference numerals for the same configuration of the prior art and the configuration of the present invention. .

As shown in FIG. 3 (a), when the compressor 17 operates in the conventional refrigerator and the high temperature and high pressure refrigerant moves through the refrigerant pipe 18 to the condenser 20, the condenser 20 The inside of the refrigerant is to exchange heat with the outside air, in which case the blowing fan 27 is rotated to send the air toward the condenser 20.

At this time, since there is no separate structure for concentrating the flow of air blown around the blower 31 toward the condenser, the air passing through the blower 31 is not only toward the condenser 20 but also of the blower 31. Scattered laterally and blowing concentration is low.

However, the present invention, as shown in Figure 3 (b), the air blowing guide member 32 which extends by a predetermined length in the direction of the condenser 20 in the edge portion of the air vent 31 of the fan case 30 Since the flow of air toward the blowing guide member 32 is provided by the blowing guide member 32, the airflow guide member 32 is not dispersed around the air outlet 31 and is advanced in the condenser 20 direction.

Therefore, the amount of air passing through the condenser 20 per unit time increases accordingly, and thus heat dissipation performance can be improved.

According to the present invention, by minimizing the dispersion of the air flow toward the condenser direction to the outside of the condenser has the effect of improving the heat dissipation performance of the condenser than before.

According to the prior art, in order to improve the heat dissipation performance of the condenser, the area in which heat transfer between the refrigerant and the air is generated has to be relatively large. The heat dissipation efficiency can be increased without increasing the heat dissipation efficiency, which can help to cool the temperature of the refrigerant in the evaporator area, thereby improving the refrigerating / cooling performance of the refrigerator.
