The present invention relates to a refrigerator for reducing noise in a cooling fan provided in a refrigerator machine room.
In general, a refrigerator is a device for supplying cold air generated in an evaporator to a storage compartment (a freezing compartment or a freezing compartment) to maintain freshness of various foods for a long time. The refrigerator includes a main body in which a storage compartment for storing food in a low temperature state is formed, and a door is installed on the front of the main body to open and close the storage compartment.
The refrigerator includes a cooling cycle configured to cool the storage compartment by circulation of the refrigerant, and the main body is provided with a mechanical compartment provided with a plurality of electrical components to form a cooling cycle.
Such a cooling cycle includes a compressor for raising / heating a low temperature / low pressure gas refrigerant to a high temperature / high pressure gas refrigerant, a condenser for condensing the refrigerant introduced from the compressor by outside air, and a narrow diameter compared to the diameter of other parts. And an expansion valve for depressurizing and expanding the refrigerant introduced from the condenser, and an evaporator for absorbing heat in the furnace as the refrigerant passing through the expansion valve is evaporated in a low pressure state as a basic component.
The machine room is provided with a blowing fan for cooling the compressor and the condenser. One side and the other side of the machine room is provided with a suction port and a discharge port for suction and discharge of the external air, respectively.
Through this structure, when the fan is rotated, air is introduced into the machine room from the inlet. The air introduced in this way is discharged back to the outside of the machine room through the discharge port while passing through the condenser and the compressor, and in this process, the condenser and the compressor are cooled by the external air.
The refrigerator includes a so-called top mount type in which a freezer compartment and a refrigerating compartment are formed up and down, and the freezer door and the refrigerating compartment door are opened and closed in the freezer compartment and the refrigerating compartment, respectively, and the refrigerating compartment and the freezer compartment are formed up and down, and the refrigerating compartment door is a refrigerating compartment. Each of the so-called bottom freezer type, which is provided to be rotated on the left and right sides of the freezer door and is configured to be opened and closed by sliding the front and rear of the freezer compartment, and the freezer compartment and the refrigerating compartment are formed side by side with each other as the refrigerator is enlarged. The freezer compartment door and the refrigerating compartment door are divided into so-called side by side types, which are configured to be opened and closed with both end portions pivoted.
The door of the refrigerator may be provided with various convenience devices such as a home bar or a dispenser that can easily take out food stored in the rear of the door without opening the door for the user's convenience. In addition, the freezing compartment or the refrigerating compartment may be provided with a rapid cooling chamber for rapid cooling of food.
On the other hand, in the conventional refrigerator machine room, a local pressure rise is caused at a specific position inside the machine room according to the operation of the cooling fan, thereby increasing the pressure before and after the cooling fan, causing noise to be generated in the cooling fan. It became.
This caused an unnecessary noise in the machine room during the operation of the refrigerator, and therefore needed an urgent solution because it could not cope with the demands of consumers who demand the operation of a quiet refrigerator.
An object of the present invention is to provide a refrigerator that can minimize the generation of noise in the machine room during operation of the refrigerator.
It is an object of the present invention to provide a refrigerator which makes it possible to maintain a pressure balance inside a machine room.
It is an object of the present invention to provide a refrigerator which enables a stable flow of discharged air discharged through a cooling fan, together with heat radiation inside the machine room.
In order to achieve the above object, a refrigerator according to the present invention includes a main body having a freezing compartment and a refrigerating compartment; A machine room disposed above the main body; And an opening in the machine room so as to communicate with the outside for pressure balancing inside the machine room.
The opening is located facing the cooling fan provided in the machine room.
The opening is arranged in the horizontal wall of the machine room.
The openings are spaced apart from each other on the horizontal wall of the machine room.
The openings are spaced apart from each other on horizontal walls of the machine room based on the compressor provided in the machine room.
The opening is characterized in that the long hole extending in the transverse direction to the machine room horizontal wall.
The opening is arranged on the vertical wall of the machine room.
The opening is provided along the longitudinal direction of the machine room vertical wall.
The refrigerator having the machine room is installed to be built-in inside the wall.
The discharged air discharged through the cooling fan is re-introduced into the machine room after some air is discharged to the outside of the machine room through the opening, and the remaining air is mixed with the air re-introduced through the compressor and discharged outside the machine room.
A constitution according to another embodiment of the refrigerator according to the present invention includes a main body having a freezing compartment and a refrigerating compartment; A machine room disposed above the main body; An opening provided in the machine room so as to communicate with the outside to balance the pressure inside the machine room; And a cooling fan provided in the machine room and disposed to be inclined toward the opening.
The openings are spaced apart from each other on the horizontal wall provided in the machine room, and are also provided on the vertical wall.
The opening is provided with a guide member for guiding the movement of the discharged air discharged from the cooling fan provided in the machine room.
The guide members are installed to face each other on the openings spaced apart from the horizontal wall.
As described above, the refrigerator according to the present invention can minimize the generation of noise inside the machine room, thereby providing a quiet operation of the refrigerator.
The refrigerator according to the present invention has an effect of operating the refrigerator in an optimal state in consideration of installation conditions of the refrigerator installed in a built-in form.
Hereinafter, an embodiment of a refrigerator according to the present invention will be described with reference to the accompanying drawings.
