Abstract
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a refrigerator, and more particularly, to a refrigerator for preventing vibration generated in a chill fan unit from spreading to components installed around the chill fan unit.
In order to achieve the above object, the present invention provides a refrigerator comprising: a main body having a storage chamber; A cool air generating chamber provided in the main body to generate cool air to be supplied to the storage chamber; A cool air fan unit provided inside the cool air generating chamber; And a vibration reduction member provided on the cooling fan unit to reduce vibration to prevent vibration generated during operation of the cooling fan unit from being transmitted to the main body.
A cooling fan unit, a vibration reduction member,
Description
BACKGROUND OF THE
A refrigerator is a household appliance for storing refrigerated or frozen storage using a refrigerant cycle. The refrigerator includes a main body having a refrigerator compartment and a freezer compartment, a door for opening and closing the refrigerator compartment and the freezer compartment, and an evaporator for generating cold air and a compressor for compressing the refrigerant.
The cool air generated in the evaporator is guided by a cool air fan unit installed adjacent to the evaporator and flows into the storage room such as the refrigerator compartment or the freezer compartment.
The cooling fan unit includes a fan, a fan motor for driving the fan, and a motor support unit for supporting and supporting the fan motor. When the fan rotates due to the operation of the motor, And vibration occurs due to driving of the motor.
Since such vibration is inevitably caused by the driving of the fan and the motor, the occurrence of the vibration itself can not be prevented. In the conventional refrigerator, the vibration of the fan and the motor is spread to the surrounding components, There has been a problem in that it occurs.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a refrigerator for preventing vibrations generated in a chill fan unit from spreading to components installed around a chill fan unit.
It is another object of the present invention to provide a refrigerator which can prevent noise from spreading and reduce noise during operation of the refrigerator.
According to an aspect of the present invention, there is provided a refrigerator comprising: a main body having a storage chamber; a cool air generating chamber provided in the main body to generate cool air to be supplied to the storage chamber; And a vibration reducing member provided on the fan unit to reduce vibration to prevent vibration generated during the operation of the cooling fan unit from being transmitted to the main body.
Wherein the cooling fan unit includes a cooling fan, a fan motor for rotating the cooling fan, and a motor support member to which the fan motor is mounted, wherein the vibration reduction member forms a rear wall of the motor support member and the cool- And is disposed between the panel members.
The motor support member includes a body portion;
A motor fixing hole formed in the body portion to fix the motor;
And a support leg part extending radially from the outer circumferential surface of the body part and coupled with the vibration reduction member.
The support legs are arranged in a plurality of spaces,
The support leg portion includes an extension extending from an edge of the body portion;
And an insertion portion provided at an end of the extended portion and into which the vibration reducing member is inserted.
And the insertion portion includes an opening for partially opening the vibration reduction member so that the vibration reduction member can be inserted or removed.
The vibration reduction member is provided in the form of a washer and the vibration reduction member is provided with a coupling groove for coupling with the support leg.
The vibration reduction member is formed of a rubber material.
And the width of the coupling groove has a size corresponding to the width of the insertion portion.
Wherein the insertion portion is provided in a circular shape having an opening at one side thereof and a size of a diameter between a portion of the surface of the coupling groove and a portion on the opposite side from the portion of the surface of the coupling groove has a size corresponding to the diameter of the insertion portion .
Wherein the width of the opening is smaller than the diameter of a portion of the surface of the coupling groove and a portion on the opposite side from the portion of the surface of the coupling groove and is elastically shrunk and deformed when the vibration reduction member passes through the opening, And when the member passes through the opening, it is elastically deformed.
The front and rear sides of the coupling groove are protruded upward from the coupling groove so that when the vibration reduction member is coupled to the insertion portion, the vibration reduction member is prevented from being separated from the insertion portion by being contacted with the vicinity of the insertion portion .
And a fixing member inserted into the vibration reduction member and coupled to the panel member to fix the cooling fan unit to the panel member.
And a guide panel disposed between the inner wall of the fan housing and the cool air fan unit to form a cool air flow path inside the fan housing.
A cool air inlet formed in the fan housing to receive cool air;
And a cool air guide hole formed in the guide panel and formed at a position corresponding to a position of the cool air inlet and the air inlet of the fan.
The panel member includes a first panel member including a cool air discharge port for guiding cool air discharged from the cool air fan unit to move to an upper portion of a rear wall of the storage chamber;
And a second panel member provided on an inner wall of the first panel member and coupled with the vibration reduction member to support the cooling fan unit.
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
