Description

Refrigerator {Refrigerator}

The present invention relates to a refrigerator, and more particularly to a refrigerator having a bracket for supporting a fan assembly including a motor and a fan for cooling the condenser.

The refrigerator is provided with a compressor for changing the low-temperature and low-pressure gaseous refrigerant into the high-temperature and high-pressure gaseous refrigerant.

A condenser for discharging the latent heat to the outside while changing the gaseous state refrigerant of the high temperature and high pressure changed in the compressor into the liquid state refrigerant of high temperature and high pressure and the expansion valve for changing the refrigerant in the liquid state changed to the low temperature and low pressure liquid in the condenser, And an evaporator that absorbs external heat while changing the refrigerant to a gaseous state.

The refrigerator has a compressor and a condenser mounted in a machine room located at a rear lower portion of the refrigerator. In the machine room, a cooling unit for cooling the heat generated from the compressor and the condenser by forcible blowing (1).

The cooling unit 1 is mainly driven by the fan 6 by the motor 5 located around the condenser 4. [

The motor bracket 7 provided in the refrigerator includes a motor 5 and a bracket elastic support 8 screwed to the bottom of the cooling unit 1.

The conventional bracket elastic support 8 can absorb the vibration of the motor 5 horizontally.

However, there is a problem that the vibration of the motor 5 can not be vertically absorbed.

Further, there is a problem that the elastic support is coupled to only one side of the motor bracket 7, and the effect of dispersion of vibration is small.

There is also a problem that the efficiency of air blowing of the fan 6 is deteriorated due to the distortion of the shaft due to the long distance between the motor 5 and the fan 6 in terms of the blowing efficiency.

In order to solve such a conventional problem, in Korean Patent Laid-Open Publication No. 2010-0041076 (hereinafter referred to as Prior Art 1), the fan bracket 60 is formed with a support portion 61 having one end connected to the inside of the fan bracket 60, An extension member 62 extending toward the center of the fan bracket 60 and a seat portion 63 connected to the other end of the extension member 62 and adapted to seat the motor 90, Respectively.

The dispersion effect of the vibration and the improvement of the blowing efficiency can be achieved by the conventional technique 1, so that it is possible to solve the problem of lowering the blowing efficiency and the vibration problem which is a problem of the prior art, but it is also possible to improve the blowing efficiency However, the technical problem of maintenance of fan or motor still existed.

In the prior art supporting the fan-motor assembly, a technique of supporting the fan-motor assembly 140 by the structure of the support portion 160 has been proposed in Korean Patent Laid-Open Publication No. 2009-0087720 (hereinafter referred to as "Prior Art 2").

The refrigerator according to claim 2 of the refrigerator of the present invention is characterized in that the supporting member is composed of a first supporting member, a second supporting member and a third supporting member.

According to the refrigerator of the present invention as described above, the following effects can be obtained.

(1) Since the supporting member is used less than in the prior art and the area where the supporting member obstructs the fan is reduced, the blowing efficiency (air flow rate) is increased.

(2) The dispersion effect of noise and vibration is improved.

(3) Since the number of supporting members for supporting the fan assembly is reduced, it is lightweight and economical.

FIG. 2 is a perspective view of a fan assembly in a refrigerator according to a preferred embodiment of the present invention; FIG.
3 is an exploded perspective view of a fan assembly in a refrigerator according to a preferred embodiment of the present invention.
4 is a front view of a bracket of a refrigerator according to a preferred embodiment of the present invention

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

First, a refrigerator according to the present invention is formed with a main body including a condenser for condensing refrigerant discharged from a compressor.

The role and description of the compressor and the condenser will be referred to the prior art, and a detailed description thereof will be omitted here.

A fan assembly (10) is located adjacent to the condenser and is capable of cooling the high temperature condenser by the refrigerant discharged from the compressor.

The fan assembly 10 is formed to include a fan 20 and a motor 30.

That is, the fan assembly 10 includes a motor 30 that applies a rotational force to the fan 20 to cool the high-temperature condenser.

The shaft 25 of the motor is inserted into a groove formed at the center of the hub 23 of the fan.

The combination of the fan 20 and the motor 30 will be described with reference to the related art and a detailed description thereof will be omitted here. Hereinafter, the combination of the bracket 150 supporting the fan assembly 10 and the frame 100 Explain structure mainly.

The fan assembly 10 is housed in a frame 100, and more specifically, in a receiving groove 103 formed in the frame 100.

The receiving groove 103 can accommodate the fan assembly 10 as well as the diameter of the receiving groove 103 so as not to interfere with the frame 100 when the fan 20 rotates is larger than the diameter of the fan 20 It is preferable to form it large.

The overall shape of the frame 100 is as follows.

First, when the frame 100 is viewed from the front, the above-described receiving groove 103 is formed at the center of the frame 100.

On the right side of the frame 100, an inclined surface 106 is formed, and a vertical surface 107 continuously connected to the inclined surface 106 is formed.

The connection portion 108 of the slope 106 and the vertical surface 107 is rounded.

The detailed shape of the frame 100 refers to the prior art, and a detailed description thereof will be omitted here.

The overall shape of the bracket 150 supporting the fan assembly 10 is as follows.

First, a hub 160 coupled to the motor 30 is formed at the center of the bracket 150.

When the support member to be described later is excluded from the bracket 150, the hub 160 is similar in shape to the original plate.

The bracket 150 is formed with the support member extending outwardly from the hub 160.

The support member extends outwardly from the hub 160, and the support member is sloped.

The support member includes a first support member 110, a second support member 120, and a third support member 130.

The support member may be coupled to the rear surface of the frame 100 using a screw or the like.

Further, the supporting member may be integrally formed with the rear surface of the frame 100.

The first supporting member 110, the second supporting member 120, and the third supporting member 130 are the same in shape, and will be described below with reference to the first supporting member 110.

The other end (111) of the first support member is connected to the hub (160).

As described above, one end 113 of the first support member is coupled to the rear surface of the frame 100 using a screw or the like, or is integrally formed with the rear surface of the frame 100. [

The support member and the hub 160 are preferably integrally formed.

The position where the other end 111 of the first support member connected to the hub 160 is formed in the hub 160 is as follows.

That is, a tangent line and a normal line are drawn with reference to an arbitrary reference point (a) in the hub 160.

The portion of the first support member 110 extending outward toward the one end 113 of the first support member is located between the tangent line and the normal line with respect to an arbitrary reference point a.

On the other hand, a portion where the other end 111 of the first support member abuts against the hub 160 is formed on the lower right side from an arbitrary reference point (a).

In another embodiment of the invention, the fan assembly 10 may be positioned between two frames 100 and then supported.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims .

The refrigerator according to the present invention is easy to maintain the fan or motor as well as improving the air flow efficiency and vibration dispersion effect and is economical because the number of supporting members is reduced as compared with the prior art.
