REFRIGERATOR AND FAN ASSEMBLY FOR REFRIGERATOR [0002]

The present invention relates to a fan assembly for a refrigerator and a refrigerator.

A refrigerator is a device intended for low-temperature storage of food, and is configured to store food in a refrigerator or a refrigerator. To this end, the refrigerator may include a cold supply device in which a cooling cycle is implemented. The cold supply device is configured such that the refrigerant undergoes a compression-condensation-expansion-evaporation process, and cold air is generated as the refrigerant circulates in the cooling cycle. The cold air generated in the evaporator of the cold supply device is supplied to the storage space of the refrigerator and the refrigerant supplied to the storage space of the refrigerator is circulated by the convection so that the food inside the refrigerator can be stored under the required temperature condition. Generally, the main body of the refrigerator has a rectangular parallelepiped shape with an open front, and a refrigerator compartment and a freezer compartment are provided inside the refrigerator compartment. A refrigerator compartment door and a freezer compartment door are provided on the front surface of the main body for selectively shielding the opening.

The refrigerator includes a top mount type in which a freezer compartment is disposed on the upper side of the refrigerator compartment and a bottom freezer type refrigerator compartment in which a freezer compartment is disposed on the lower side of the refrigerator compartment, And a side by side type in which the freezing compartment and the refrigerating compartment are arranged in both the lateral directions.

On the other hand, in order for the user to take out the food stored in the refrigerator, the refrigerator door or the freezer compartment door must be opened, whereby the high-temperature air outside the refrigerator is introduced into the refrigerator compartment or the freezer compartment. The outside air supplied from outside causes the inside temperature of the refrigerator to rise, and the cold supply must be operated to maintain the proper temperature. However, since it takes a considerable amount of time for the cool air supply device to operate to generate cool air, to return the generated cool air to the proper temperature after the cool air is introduced into the freezing chamber and the cold storage chamber and to uniformize the temperature distribution, The freshness of the food is adversely affected.

Particularly, in the case of a refrigerator such as a top mount type using one evaporator, cold air generated in the evaporator flows into the refrigerating chamber after circulating in the freezing chamber. Therefore, when the refrigerating chamber door is opened and the high temperature outdoor air flows into the refrigerating chamber, It takes quite a long time to recover to the temperature.

In order to solve such a problem, a technique has been proposed in which a blower fan for generating forced convection is provided so that the cold air in the freezer compartment or the refrigerating compartment can be circulated more easily.

However, as a blowing fan, a small-sized low-output fan is used due to problems such as space constraints, noise, and vibration, and thus there is a limit in stabilizing the internal temperature quickly and uniformizing the temperature distribution even when the blowing fan is used .

As described above, the fan assembly 200 is capable of discharging the air farther and stronger by imparting the rotatability to the flow during discharge of the air. In addition, since the flow sucked into the fan assembly 200 can serve to block the flow discharged from the fan assembly, the straightness of the discharged air can be further improved.

The front surface of the fan assembly 200 may have a predetermined shape centered on a fan for generating a flow. In the present embodiment, the vertexes are provided in a rounded rectangular shape. However, the spirit of the present invention is not limited thereto, and the fan assembly 200 may have any shape such as a circle, a square, and the like.

Specifically, the fan assembly 200 includes a housing 210 for providing a flow space in which a traveling direction of air is changed so that air introduced into the inner space from the front of the fan assembly 200 can be discharged forward, A fan unit 230 accommodated in a central portion of the suction guide unit 220 and a fan unit 230 accommodated in the suction guide unit 220. The suction guide unit 220 includes a suction guide unit 220 for supplying air to the inside space of the suction guide unit 210, A damping unit 240 which is fixed to the fan unit 230 and absorbs vibration generated in the fan unit 230, and a damping unit 240 which rotates the flow of the air discharged by the fan unit 230 in one direction about the traveling direction of the air A discharge guide unit 250 and a fixing unit 260 for fixing the discharge guide unit 250 to the suction guide unit 220. [ Here, one direction indicating the rotational direction of the air can be understood as a clockwise or counterclockwise direction, and the other direction relative to the direction can be understood as a counterclockwise or clockwise direction.

For example, the housing 210 may be formed such that the front surface of the multi-duct 100 is recessed rearward. Accordingly, the fan assembly 200 can be installed without invading the internal storage space. Of course, according to the embodiment, the housing 210 may be separately manufactured and assembled into the multi-duct 100, or may be provided in a form protruding from the multi-duct 100. Also, as described above, the housing 210 may be provided in the inner case of the main body 10, rather than the multi-duct 100.

The housing 210 may be provided to form a closed space behind the suction guide unit 220 and the fan unit 230 when the fan assembly 200 is installed in the refrigerator 1. [ Thus, the air introduced into the inner space of the housing 210 from the front of the fan assembly 200 through the suction guide unit 220 can be discharged to the front of the fan assembly 200 again.

The housing 210 may have a stepped portion 212 for supporting the rim of the suction guide unit 220 and may include a suction guide unit 220 for fixing the suction guide unit 220 along the periphery of the stepped portion 212. [ A fixing hole 214 may be formed. The suction guide unit fixing hole 214 may be formed by cutting a part of the multi-duct 100 forming the housing 210. In this embodiment, four suction guide unit fixing holes 214 are formed along the periphery of the inlet of the housing 210.

On the other hand, a protrusion 216 protruding toward the center of the fan 238 of the fan unit 230 may be provided on the rear surface of the housing 210. The protrusion 216 is formed to be spaced apart from the fan 238 by a predetermined distance so that the air introduced into the housing 210 through the suction guide unit 220 can be guided more smoothly through the fan 238 have.

The side surface 218 forming the inner space of the housing 210 may be formed inclined to the center side so that the air introduced through the suction guide unit 220 can be guided more toward the fan unit 230 .

In this embodiment, the housing 210 forms a closed space behind the suction guide unit 220 and the fan unit 230, but the spirit of the present invention is not limited thereto. For example, the upper surface of the housing 210 may be opened to communicate with a cool air passage formed in the interior of the multi-duct 100. In this case, the cool air supplied to the multi- And can be discharged from the fan assembly 200 by mixing with the air introduced from the inside of the apparatus.

The suction guide unit 220 is coupled to the opening of the housing 210 to form a front surface of the fan assembly 200 and provides a passage through which the air flows into the inner space of the housing 210. Specifically, the suction guide unit 220 includes an outer frame 221 which forms a rim and an inner side portion 223 which is disposed inside the outer frame 221 at a predetermined distance from the outer frame 221 to form a suction passage 229 A frame 222 and a suction guide rib 223 for concentrating the air introduced into the suction passage 229 toward the fan unit 230 and a suction guide rib 223 connected to the inner frame 222 and connected to the fan unit 230 and the damping unit A fan unit accommodating portion 224 capable of accommodating the fan unit accommodating portion 224 and a fan unit accommodating portion 224 capable of accommodating the ejection guide unit 250, A first engaging hole 226 formed in the fan unit accommodating portion 224 and into which the fixed portion 264 of the fixed unit 260 is inserted and a second engaging hole 226 formed in the rear end portion of the fan unit accommodating portion 224 A fan unit support portion 227 for preventing rearward departure of the fan unit 230 and the damping unit 240, Is formed around the 221 may include a locking projection 228 for fixing the outer frame 221 to the housing 210.

The outer frame 221 may have a shape and a size that can be installed in the housing 210 and a rim of the outer frame 221 may be formed to be seated in the step 212.

The outer frame 221 and the inner frame 222 have surfaces facing each other and may be formed so as to surround the perimeter of the fan unit 230 housed inside. The width of the outer frame 221 in the front and rear direction may be wider than that of the inner frame 222. The suction guide ribs 223 connecting the outer frame 221 and the inner frame 222 may be thicker Can be formed. Accordingly, the suction guide unit 220 can guide the flow formed around the rim of the fan assembly 200 more smoothly toward the center direction and enter the inner space of the housing 210.

The suction passage 229 which is a space between the outer frame 221 and the inner frame 222 functions as a passage through which the air flows into the inner space of the housing 210 and has a force for sucking air into the inside of the housing 210 Is generated by the driving of the fan unit 210.

One end of the suction guide rib 223 is fixed to the outer frame 221 and the other end is fixed to the inner frame 222. A plurality of suction guide ribs 223 may be formed on the suction passage 229 at predetermined intervals. The suction guide ribs 223 can be radially formed so that air can be smoothly guided to the fan unit 230 side provided at the center of the fan assembly 200. [ That is, the gap between the suction guide ribs 223 may be formed so that the outer frame 221 side is wider than the inner frame 222 side.

The fan unit 230 and the damping unit 240 may be inserted into a central portion of the inner frame 222. [ The fan unit accommodating portion 224 may extend rearward from the inner frame 222 so as to surround the fan unit 230 and the damping unit 240 inserted into the center of the inner frame 222. The extension length of the fan unit receiving portion 224 may be set such that the fan unit 230 and the damping unit 240 do not protrude forward of the outer frame, May correspond to the position of the rear end portion of the front end portion 222 of the second housing 222.

A discharge guide unit support portion 225 is formed at a connection portion between the inner frame 222 and the fan unit receiving portion 224 so that the rear surface of the discharge guide unit 250 can be supported. The discharge guide unit support part 225 may have a step shape in which a rim portion of the discharge guide unit 250 can be supported. When the discharge guide unit 250 is seated on the discharge guide unit support part 225, 250 and the fan unit 230 may be spaced apart from each other by a predetermined distance. That is, the fan unit 230 may be disposed so as not to directly contact the discharge guide unit 250. Thus, it is possible to prevent the vibration generated in the fan unit 230 from being directly transmitted to the discharge guide unit 250, thereby preventing noise and vibration from occurring.

The first coupling hole 226 may be formed by cutting the side surface of the fan unit receiving portion 224. The first engaging hole 226 may have a size and a shape corresponding to the fixing portion 264 so that the fixing portion 264 of the fixing unit 260 is resiliently deformed and engaged. The fixing portion 264 of the fixing unit 260 may be fixed to the first coupling hole 226 through the discharge guide unit 250 and may be fixed to the coupling portion 264 of the fixing portion 264 and the first coupling hole 226 The discharge guide unit 250 can be fixed to the suction guide unit 220. [

The fan unit support portion 227 may have a predetermined area to support the damping unit 240 surrounding the fan unit 230 and may be provided in the form of a plate facing the fan unit 230. In the present embodiment, as the fan unit supporting portion 227, a triangular plate connecting corners around the vertex of the fan unit accommodating portion 224 is formed for each vertex. However, the shape of the fan unit supporting portion 227 And positions and numbers do not limit the spirit of the present invention. At this time, the size and position of the fan unit support portion 227 may be limited to the outer region of the fan unit 230 so as not to block the flow entering the fan unit 230.

The locking protrusion 228 is provided around the outer frame 221 so as to be inserted into the suction guide unit fixing hole 214 of the housing 210. Here, the latching protrusion 228 is elastically deformed to a predetermined level when it is fitted into the suction guide unit fixing hole 214. After the latching protrusion 228 is inserted into the suction guide unit fixing hole 214, a predetermined external force is applied It can be prevented from falling out. The outer frame 221 can be fixed to the housing 210 by the engagement of the locking protrusion 228 and the suction guide unit fixing hole 214. In this embodiment, the locking protrusions 228 are hooks protruding from the center of the outer surface of each corner of the outer frame 221, for example.

The fan unit 230 is supplied with power and drives the fan 238 to generate a forced flow. Specifically, the fan unit 230 includes a case 232 formed to correspond to the shape of the inner frame 222 of the suction guide unit 220 and having a hole through which air can pass, A supporting rib 236 for supporting the driving unit 234 to the case 232 and a fan 234 connected to the driving unit of the driving unit 234. The driving unit 234 includes a driving unit such as a motor, 238 < / RTI > The fan unit 230 may be an axial fan that extends in the forward and backward directions and discharges wind from the rear of the fan unit 230 forward. Such an axial fan has an advantage in that it is advantageously installed in the inner space of the refrigerator 1 having a narrow front-rear direction and large space limitation.

Here, the fan unit 230 may be configured such that the direction of the whirling flow generated when the air is discharged by the rotation of the fan 238 can be rotated in one direction with respect to the traveling direction of the air. For example, the flow formed by the rotation of the fan 238 of the fan unit 230 may be a whirlpool flow that is rotated counterclockwise about the direction of flow. In other words, the air inside the refrigerating chamber 11 is concentrated through the suction guide unit 220 toward the fan unit 230, whirls counterclockwise by the fan unit 230, As shown in Fig. At this time, when the flow is observed from the front of the fan assembly 200, the air discharged through the fan unit 230 appears to be discharged in a clockwise direction. However, It is a counterclockwise whirl.

The damping unit 240 absorbs vibration generated in the fan unit 230, thereby reducing vibration and noise generated by the fan assembly 200. For this purpose, the damping unit 240 may be formed of a material having a predetermined elastic force. For example, the damping unit 240 may be made of rubber. Specifically, the damping unit 240 includes a side damper 242 which surrounds the case 232 of the fan unit 230 and absorbs the lateral vibration of the fan unit 230, A front damper 243 which is formed on the front side of the side damper 242 and absorbs the vibration of the fan unit 230 and has a plurality of dustproof protrusions 244 which can be in point contact with the back surface of the discharge guide unit 250, And a fan unit 230 which is formed on the rear surface side of the side damper 242 so as to be in close contact with the rear surface of the fan unit 230 and absorbs vibration of the fan unit 230, And a rear damper 245 having a plurality of anti-vibration protrusions 246 that can be contacted.

The side damper 242 may be formed so as to correspond to the outer shape of the fan unit 230 as a whole, and in this embodiment, the vertexes are rounded to have a rectangular front side.

The front damper 243 and the rear damper 245 may be provided at two corners around the vertex of the side damper 242 and may cover the front and rear portions of the fan unit 230, respectively. The front damper 243 is positioned at both ends of one diagonal line of the side damper 242 and the rear damper 245 is positioned at both ends of the diagonal line of the other side of the side damper 242 . In this case, since it is easy to insert the fan unit 230 into the damping unit 240, the productivity of the product can be improved. The front damper 243 and the rear damper 245 may have a size and shape such that the flow generated by the fan unit 230 is not disturbed. However, the present invention is not limited to this, and the position, shape and size of the front damper 243 and the rear damper 245 can be appropriately adjusted according to the embodiment.

The vibration damping protrusions 244 and 246 provided on the front damper 243 and the rear damper 245 may be protrusions protruding from the front damper 243 and the rear damper 245 by a predetermined height, It may have a hemispherical shape so that point contact can be realized. The vibration damping protrusions 244 and 246 are provided so as to be in point contact with the peripheral structure, thereby minimizing the contact area between the damping unit 240 and the peripheral structure, thereby reducing the vibration transmitted to the peripheral structure through the damping unit 240 Can be minimized. Specifically, the vibration generated in the fan unit 230 is primarily absorbed by the damping unit 240, and secondarily transmitted through the damping unit 240 to the peripheral structure. The damping unit 240 and the peripheral structure By reducing the contact area, the transmitted vibration can be generated only locally, which not only reduces the amount of vibration transmitted but also makes it easier to control the vibration. In order to avoid the resonance frequency of the fan unit 230 to be used, the size of the vibration damping protrusions 244 and 246 By adjusting the number, position, and height of the fan unit 230, resonance of the fan unit 230 can be more easily prevented.

At this time, one side surface or a plurality of side surfaces of the side damper 242 may be spaced apart from the side surface of the fan unit receiving portion 224 of the suction guide unit 220 by a predetermined distance. As a result, the portion where the damping portion 240 is in contact with the peripheral structures is further reduced, and the vibration transmitted to the point contact portion by the vibration preventing protrusions 244, 246 is further increased, Can be more effectively reduced.

The discharge guide unit 250 forms a front central portion of the fan assembly 200 and provides a passage through which the air in the inner space of the housing 210 is discharged into the storage space of the refrigerator 1. [ Specifically, the discharge guide unit 250 is coupled to the inner frame 222 of the suction guide unit 220 and shields a corresponding area of the case 232 of the fan unit 230, A shielding plate 253 formed at the center of the hole of the cover 251 and shielding the position corresponding to the driving unit 236 of the fan unit 230, A discharge guide rib 254 which rotates the air discharged to the discharge passage 252 which is a space between the discharge rollers 253 and 253 in one direction with respect to the advancing direction of the air to generate a whirling flow, And a second engaging hole 256 into which the fixing portion 264 of the second engaging portion 260 is inserted.

The rim of the cover 251 may be a plate having a shape corresponding to the inner frame 222 and the discharge guide unit support portion 225 so as to be seated in the discharge guide unit support portion 225 of the suction guide unit 220. [ The cover 251 can block unnecessary flow by shielding the other area except for the area blowing forward by the fan unit 230 among the openings at the center of the inner frame 222. [

The shielding plate 253 may have a size and a shape corresponding to the driving unit 236 of the fan unit 230 and may include a cover 251 and a discharge passage 252, So that the flow can be concentrated in the discharge passage 252.

A discharge passage 252 which is a space between a portion forming the center hole of the cover 251 and the shielding plate 253 functions as a passage through which air is discharged from the inner space of the housing 210, Is generated by driving the fan unit (230). At this time, the discharge guide unit 250 is disposed at the center of the suction guide unit 220, and the discharge passage 252 is surrounded by the suction passage 229. As a result, the flow of the air discharged from the discharge passage 252 can be confined to the flow of the air flowing into the suction passage 229, so that the straightness of the air discharged from the discharge passage 252 can be further improved .

One end of the discharge guide rib 254 is fixed to the cover 251 and the other end is fixed to the shielding plate 253. A plurality of such discharge guide ribs 254 may be formed on the discharge passage 252 at predetermined intervals. The discharge guide ribs 254 may be inclined so that air entering through the discharge passage 252 may be rotated in one direction with respect to the traveling direction of the air. In this embodiment, the discharge guide ribs 254 are formed so that air flowing into the inner space of the housing 210 through the discharge passage 252 flows counterclockwise about the advancing direction (the direction perpendicular to the paper surface of FIG. 9) And may be formed to be inclined counterclockwise about the rotation axis C of the fan unit 230 when viewed from the rear of the fan assembly 200 so as to be rotated. That is, the end of the one of the discharge guide ribs 254 on the side of the shield plate may be positioned more biased in the counterclockwise direction about the advancing direction of air than the cover side end. At this time, the discharge guide ribs 254 may have curved surfaces that are convex in a direction tilting so that the whirling flow can be generated more smoothly. That is, the discharge guide ribs 254 may be formed to be convex in the counterclockwise direction with respect to the traveling direction of the air.

In addition, according to the embodiment, the discharge guide ribs 254 may be formed to be twisted in a direction in which a whirlpool is to be formed so that the whirlpool flow can be smoothly formed.

The second coupling hole 256 may be formed by cutting the side surface of the cover 251. The fixing portion 264 of the fixing unit 260 passes through the second coupling hole 256 and is inserted into the first coupling hole 226 The first engaging hole 226 and the second engaging hole 266 may be provided at positions corresponding to the fixing portion 264 and the first engaging hole 226, respectively. The fixing portion 264 of the fixing unit 260 may be fixed to the suction guide unit 220 through the second coupling hole 256 and may be fixed to the coupling portion 264 The discharge guide unit 250 can be fixed to the suction guide unit 220. [

Although the ejection guide unit 250 is fixed to the suction guide unit 220 by the fixing unit 260 and is also fixed to the housing 210 in the present embodiment, May be fixedly coupled to the direct suction guide unit 220 or fixed to the housing 210.

The fixing unit 260 fixes the discharge guide unit 250 to the suction guide unit 220 and has a shape corresponding to the cover 251 of the discharge guide unit 250, And a fixing portion 264 extending to the rear of the decoupling plate 262 and formed with a hook at an end thereof.

A hole is formed in the center of the decoupling plate 262 so that air discharged through the discharge guide unit 250 can pass therethrough and the decoupling plate 262 is coupled to the cover 251, The appearance can be beautiful.

The fixing unit 260 and the fixing unit 264 may be combined with each other so that the fixing unit 260 and the fixing unit 264 are fixed to each other. Various embodiments may be applied as a method of fixing the discharge guide unit 250 to the suction guide unit 220. [ For example, the fixed unit 260 may be a hook formed integrally with the discharge guide unit 250, and the discharge guide unit 250 may be directly coupled to the suction guide unit 220 or the housing 210.

Hereinafter, a method of assembling the fan assembly 200 having the above-described structure will be described.

First, the fan unit 230 is fitted into the space between the side damper 242 of the damping unit 240, the front damper 243 and the rear damper 245, and the case 232 of the fan unit 230, The inner surfaces of the dampers 242, 243, and 245 can be in close contact with each other. Since the damping unit 240 is made of a material having elasticity, the operator can elastically deform the front damper 243 or the rear damper 245 when assembling the fan unit 230, The fan unit 230 can be easily pushed into the space.

The fan unit 230 and the damping unit 240 are fitted into the fan unit receiving portion 224 of the suction guide unit 220. At this time, the dustproof protrusion 246 formed on the rear damper 245 of the damping unit 240 may be disposed so as to be in point contact with the fan unit support 227 of the suction guide unit 220. In addition, one side surface or a plurality of side surfaces of the side damper 242 may be spaced apart from the side surface of the fan unit support portion 227 by a predetermined distance.

The discharge guide unit 250 is coupled to the suction guide unit 220 so as to cover the fan unit 230 and the damping unit 240 and be supported by the discharge guide unit support part 225 of the suction guide unit 220. [ do. At this time, the engagement state of the discharge guide unit 250 can be maintained in an assembled state in which the cover 251 is in close contact with the discharge guide unit support portion 225. At this time, when the cover 251 is brought into close contact with the discharge guide unit supporter 225, the dustproof protrusion 244 of the front damper 243 is in point contact with the back surface of the cover 251, 1 coupling holes 226 can be aligned with each other.

The fixing unit 260 is coupled to the front surface of the discharge guide unit 250 so that the fixing portion 264 can pass through the second fitting hole 256. The fixing portion 264 can be elastically deformed by sequentially passing through the second engaging hole 256 and the first engaging hole 226. When the inserting is completed, the fixing portion 264 returns to its original state, The unit 220 can be fixed firmly.

When the fixing of the discharge guide unit 250 and the suction guide unit 220 is completed by the fixing unit 260, the suction guide unit 220 is coupled to the housing 210, The suction guide unit 220 can be fixed to the housing 210 by fitting the suction guide unit 220 into the suction guide unit fixing hole 214 of the housing 210. [

Here, the suction guide unit 220 and the housing 210 may be engaged before or after the fan unit 230 is assembled to the suction guide unit 220.

Hereinafter, the operation and effects of the fan assembly 200 having the above-described structure will be described.

The fan assembly 200 is provided on one side wall of the storage space of the refrigerator 1 so as to suck air in the hearth and discharge it, so that the fan assembly 200 generates strong whirlpool flow rotating in one direction, It is possible to quickly return the internal temperature to an appropriate temperature and uniform the internal temperature distribution. In addition, since the flow sucked into the fan assembly 200 can serve to block the flow discharged from the fan assembly, the straightness of the discharged air can be further improved.

Specifically, when the fan unit 230 of the fan assembly 200 is driven, a flow that moves forward from the rear of the fan unit 230 by rotation of the fan 238 is generated. By this flow, the air outside the fan assembly 200 flows into the inner space of the housing 210 through the suction guide unit 220.

Air passing through the suction guide unit 220 is guided to the suction guide rib 223 in the direction of the fan unit 230. The air that has passed through the suction guide unit 220 may be reflected by colliding against the inner wall of the housing 210 or may be guided to the rear of the fan unit 230 by the side surface 218 and the protrusion 216 of the housing 210 have.

The fan unit 230 rotates the air guided to the rear of the fan unit 230 in one direction about the moving direction, that is, the direction of moving forward from the rear of the fan unit 230, and discharges the air.

The air discharged from the fan unit 230 passes through the discharge guide unit 250 and is guided by the discharge guide ribs 254 to rotate in one direction about the traveling direction again. That is, once again, the whirlpool flow can be further strengthened.

Through this process, the air discharged through the fan assembly 200 can have a very strong whirl flow. When air is swirled out, the straightness of the flow is improved, and as the straightness is improved, the flow of air can be further advanced, which can cause strong convection in the storage space of the narrow refrigerator 1. [

At this time, the discharge guide unit 250 is disposed at the center of the suction guide unit 220, and the discharge passage 252 is surrounded by the suction passage 229. As a result, the flow of the air discharged from the discharge passage 252 can be confined to the flow of the air flowing into the suction passage 229, so that the straightness of the air discharged from the discharge passage 252 can be further improved .

Particularly, even if a small-sized axial fan is used as the fan unit 130 in the fan assembly 200, it is possible to rotate the flow in the discharge guide unit 250 to generate a strong whirl flow, The convection effect within the bar and storage space can be greatly improved compared to the case where only the axial fan is provided.

As a result, the temperature inside the storage space of the refrigerator 1 can be rapidly made uniform. Particularly, when various types of food are stored in the refrigerating chamber 1, the convection may be disturbed and the cold air may not circulate smoothly. In the case where the fan assembly 200 according to the present embodiment generates a whirling flow with improved straightness It is possible to supply cold air to every corner of the refrigerating chamber 1.

When the doors 13 and 14 are opened and the outside air flows into the storage space of the refrigerator 1 to improve the inside temperature of the refrigerator 1, if the fan assembly 200 is driven to strongly induce forced convection, So that the internal temperature can be quickly returned to the proper temperature by rapidly lowering the temperature.

This effect is particularly advantageous in that a single evaporator is provided and cool air generated in the evaporator is supplied to the refrigerator compartment 11 via the freezer compartment 12, It can be more remarkable than in the refrigerator 1 which takes a long time to return to the proper temperature after entering the outside air like the mount type refrigerator 1.

For this purpose, the refrigerator 1 may further include a door sensor (not shown), and a control unit (not shown) of the refrigerator 1 may detect opening and closing of the doors 13 and 14 The fan assembly 200 may be driven for a certain period of time to generate forced convection in the storage space.

The controller 1 of the refrigerator 1 drives the fan assembly 200 when a temperature rise of the storage space is sensed by the temperature sensor, Forced convection can be generated.

The controller 1 of the refrigerator 1 drives the fan assembly 200 when the defrost heater is driven and the cooler supply device is operated, Forced convection may be generated inside.

Here, the control unit of the refrigerator 1 may include both the door sensor and the temperature sensor, and may drive the fan assembly 200 in consideration of both of them. For example, the control unit of the refrigerator 1 may operate the fan assembly 200 for a predetermined time only when the temperature of the storage space rises above the set value after the opening and closing of the doors 13 and 14 are sensed . Alternatively, the control unit of the refrigerator 1 may operate the fan assembly 200 for a predetermined time only when the temperature of the storage space rises above a predetermined value after driving the defrost heater.

Meanwhile, although the fan assembly 200 is used, the fan assembly 200 may generate less noise and less vibration. Specifically, the damping unit 240 provided in the fan assembly 200 surrounds the fan unit 230 and can absorb vibration generated from the fan unit 230. Since the vibration damping protrusions 244 and 246 are in point contact with the suction guide unit 220 and the discharge guide unit 250, the vibration in the forward and backward directions generated by the fan unit 30 is transmitted through the damping unit 240 at a minimum To the peripheral configuration.

In addition, when one side or a plurality of side surfaces of the side damper 242 of the damping unit 240 is disposed to be spaced apart from the side surface of the fan unit accommodating portion 224 by a predetermined distance, the transmission of vibration to the peripheral configuration is reduced Vibration transmission can be concentrated on the point-contacted portion, so that the overall vibration and noise reduction effect of the fan assembly 200 can be further improved.

When the fan assembly 200 is provided in the multi-duct 100 as in the present embodiment, it is not necessary to apply additional processing to the inner case of the main body 10 in order to fix the fan assembly 200, Since the fan assembly 200 can be installed by simply changing the injection mold of the duct 100, the productivity can be improved.

When a discharge port 102 for discharging cold air is provided on the side of the multi-duct 100, a part of the cool air discharged laterally and moved along the inner case of the main body 10 directly affects the fan assembly 200 It can spread to the inside of the storage space and the cooling effect can be further improved. That is, the direction in which the multi-duct 100 discharges the cool air through the discharge port 102 and the direction in which the fan assembly 200 discharges the air may be different from each other. For this, some of the discharge ports 102 may be provided at a height corresponding to the installation position of the fan assembly 200.

In addition, the fan assembly 200 is configured such that the air discharged from the fan assembly 200 and the refrigerant discharged to the storage space through the discharge port 102 are mixed with the food stored in the food storage means 15 And may be arranged to be spaced apart from the storage means 15.

Hereinafter, a fan assembly of a refrigerator according to another embodiment of the present invention will be described with reference to FIGS. 11 and 12. FIG. However, the other embodiment differs from the above-described embodiment in the structure of the suction guide unit. Therefore, differences will be mainly described, and the description of the same embodiment and the reference numerals will be used for the same parts.

FIG. 11 is a perspective view of a suction guide of a fan assembly of a refrigerator according to another embodiment of the present invention, and FIG. 12 is a front view of a fan assembly to which a suction guide of FIG. 11 is applied.

11 and 12, the suction guide unit 220 'of the fan assembly of the refrigerator according to another embodiment of the present invention rotates the air flowing into the suction passage 229 in one direction with respect to the traveling direction of air And a suction guide rib 223 'for generating a whirl flow.

Specifically, the suction guide rib 223 'may be inclined so that the air entering through the suction passage 229 may be rotated in one direction with respect to the traveling direction of the air. In this embodiment, the suction guide rib 223 'is configured such that the air introduced into the inner space of the housing 210 through the suction passage 229 is rotated counterclockwise about the traveling direction (the paper surface direction in FIG. 9) The fan unit 230 may be inclined counterclockwise about the rotation axis C of the fan unit 230 when viewed from the front of the fan assembly 200. [ That is, the inner frame side end of one of the suction guide ribs 223 'may be positioned more biased counterclockwise about the advancing direction of air than the outer frame side end portion. At this time, the suction guide rib 223 'may have a curved surface that is convexly formed in a direction tilting so that a whirling flow can be smoothly generated. That is, the suction guide rib 223 'may be formed to be convex in the counterclockwise direction with respect to the traveling direction of the air.

Also, according to the embodiment, the suction guide rib 223 'may be formed to be twisted in a direction in which a whirlpool is to be formed so that the whirlpool flow can be smoothly formed.

At this time, the fan unit 230 is arranged so that the direction of the whirl of the flow generated when the air is discharged by the rotation of the fan 238 corresponds to the direction of the whirling of the flow with respect to the traveling direction of the air formed by the suction guide unit 220 ' The rotation direction of the driving device and the twist direction of the blades of the fan 238 can be adjusted. That is, when the flow formed by the suction guide unit 220 'is a counter-clockwise rotation about the traveling direction of the flow as in the present embodiment, the rotation of the fan 238 of the fan unit 230 Which is rotated in a counterclockwise direction about the traveling direction of the flow flow. In other words, the air in the refrigerating chamber 11 is swirled in the counterclockwise direction through the suction guide unit 220 and flows into the inner space of the housing 210, whirls counterclockwise by the fan unit 230, (Not shown). The fan unit 230 is thus provided to generate a whirl flow in the same direction as the whirl flow formed by the suction guide unit 220 ', so that the whirl flow can be made even stronger.

At this time, when the flow is observed from the front side of the fan assembly 200, the air entering the inner space of the housing 210 swirls in a counterclockwise direction and the air discharged through the fan unit 230 flows clockwise It appears to be dispensed by a whirlwind, but both of these flows are counterclockwise whirls when viewed from the direction of the air.

Both of the guides 220 'and 250 are moved in one direction (counterclockwise in the present embodiment) with respect to the advancing direction of the air in relation to the direction of the whirlpool flow generated by the suction guide unit 220' and the discharge guide unit 250 Direction). Here, air is sucked (sucked) from the front to the rear of the refrigerator 1 through the suction guide unit 220, and is discharged from the rear of the refrigerator 1 opposite to the suction direction through the discharge guide unit 250 (Discharging) the air. 9, when the fan assembly 200 is viewed from the front of the fan assembly 200, that is, inside the storage space, the flow entering through the suction guide unit 220 ' (One direction), and the flow discharged through the discharge guide unit 250 can be observed as being rotated clockwise (the other direction). Likewise, the direction in which the suction guide ribs 223 'are tilted and the direction in which the discharge guide ribs 254 are inclined can be formed opposite to each other when viewed from the front of the fan assembly 200.

Hereinafter, the operation and effect of the fan assembly 200 according to another embodiment of the present invention will be described.

When the fan unit 230 of the fan assembly 200 is driven, a flow that moves forward from the rear of the fan unit 230 by rotation of the fan 238 is generated. By this flow, the air outside the fan assembly 200 flows into the inner space of the housing 210 through the suction guide unit 220 '.

The air passing through the suction guide unit 220 'is rotated in one direction about the advancing direction of the air, that is, the direction of entering the inner space of the housing 210, by the suction guide rib 223' A swirling flow rotating in one direction is generated in the air flowing into the inner space of the housing 210. In this embodiment, the air entering the inside of the housing 210 through the suction guide unit 220 'is rotated counterclockwise about the traveling direction of the air.

The air passing through the suction guide unit 220 'and whirling is guided to the rear of the fan unit 230. Since the fan unit 230 is configured such that the direction of the whirl of the flow generated when the air is discharged can be the same as the direction of the whirl of the flow with respect to the traveling direction of the air formed by the suction guide unit 220 ' The air that is guided to the rear of the unit 230 is rotated in one direction about the moving direction, that is, the direction of moving forward from the rear of the fan unit 230 to discharge the air. In other words, the whirlpool flow, which is formed by the suction guide unit 220 'and is rotated in one direction, can have a stronger flow by the second fan unit 230.

The air discharged from the fan unit 230 passes through the discharge guide unit 250 and is guided by the discharge guide ribs 254 to rotate in one direction about the traveling direction again. That is, the tornado flow can be further strengthened once again in the third order.

Through this process, the air discharged through the fan assembly 200 can have a very strong whirl flow. When air is swirled out, the straightness of the flow is improved, and as the straightness is improved, the flow of air can be further advanced, which can cause strong convection in the storage space of the narrow refrigerator 1. [

Also, since the air supplied to the fan unit 230 has a whirling flow, the load applied to the fan unit 230 can be reduced, and the vibration and noise can be reduced.
