Description

Refrigerator {REFRIGERATOR}

The present invention relates to a refrigerator.

A refrigerator is a device that cools food or medicines or stores them at a low temperature to prevent spoilage and deterioration.

The refrigerator includes a storage compartment in which food or medicine is stored, and a cooling device for cooling the storage compartment. An example of the cooling device may be composed of a refrigeration cycle device including a compressor, a condenser, an expansion mechanism, and an evaporator. Another example of the cooling device may be composed of a thermoelectric module (TEM) using a phenomenon in which a temperature difference occurs in both end surfaces of different metals when different metals are combined and an electric current flows.

The refrigeration cycle device has higher efficiency than the thermoelectric module, but has a disadvantage in that the compressor is noisy when driving.

On the other hand, the thermoelectric module has low efficiency compared to the refrigeration cycle device, but has the advantage of low noise, and can be used in a CPU cooling device, a temperature control seat of a vehicle, a small refrigerator, and the like.

However, a refrigerator using a refrigerant is common, but a refrigerator using a thermoelectric module has been manufactured and not widely used. In particular, in order to lower the cooling temperature through the thermoelectric module, it is necessary to cool the thermoelectric module, and it is not easy to apply the cooling structure of the thermoelectric module to a refrigerator.

In particular, a thermoelectric module refrigerator has a great advantage in that it produces less noise than a refrigerant refrigerator, but there is a risk that noise may be generated due to external factors in the cooling structure of the thermoelectric module. That is, when the air does not flow smoothly into and out of the refrigerator, the concern about noise generation may increase.

Accordingly, there is a need to provide a refrigerator capable of providing effective efficiency while maximally maintaining the advantages of a thermoelectric module refrigerator.

In more detail, the lower end 46b of the lower discharge hole 46 may be located at the rear upper side of the upper end 63 on the rear side of the first accommodating member 6 .

The rear surface 61 of the first accommodating member 6 may be disposed to face the bottom of the lower discharge hole 46 with respect to the horizontal direction, and the lower discharge hole 46 may be disposed to face the bottom of the lower discharge hole 46 with respect to the horizontal direction. ) and may not overlap. That is, the first accommodating member 6 may be disposed so as not to cover the lower discharge hole 46 in the horizontal direction.

Accordingly, the flow of low-temperature air discharged to the lower discharge hole 46 may not be disturbed by the first storage member 6 , so that the air circulation inside the storage chamber S may be smooth. In addition, since the low-temperature air descends, the food stored in the first storage member 6 can be maintained at a low temperature.

In order to further facilitate air circulation in the storage chamber S, the lower discharge hole 46 and the first accommodating member 6 may be disposed to be spaced apart from each other. The lower end 46b of the lower discharge hole 46 and the first accommodating member 6 are spaced apart from each other by the first horizontal distance D1 in the horizontal direction, and at the same time, the first vertical spaced distance H1 in the vertical direction. ) can be spaced apart.

In this case, the rear surface of the storage compartment S may be the front surface of the fan cover 41 . The first vertical separation distance H1 may be a height difference between the lower end 46b of the lower discharge hole 46 and the upper end 60 of the first accommodating member 6 .

A portion of the upper discharge hole 45 may overlap the second accommodating member 7 in the horizontal direction. In more detail, a portion of the upper side of the upper discharge hole 45 may face between the upper end 70 of the second storage member 7 and the upper surface of the storage unit S, and the lower portion of the upper discharge hole 45 is The rear surface 71 of the second storage member 7 may face each other.

The upper end 45a of the upper discharge hole 45 may be located at the rear upper side of the rear upper end 73 of the second storage member 7 .

Accordingly, compared to the case where the upper discharge hole 45 does not overlap the second storage member 7 in the horizontal direction, the height of the storage compartment S can be lowered, and the refrigerator can be compactly formed.

In addition, as described above, in the fan cover 41 , the inner suction hole 44 may be formed closer to the lower discharge hole 46 than the upper discharge hole 45 .

Accordingly, the height of the storage chamber S for satisfying the positional relationship between the accommodating members 6 and 7 and the inner suction hole 44 and the inner discharge hole 45 and 46 described above can be further lowered.

At least a portion of the rear surface 71 of the second storage member 7 may be inclined upward. A portion of the rear surface 71 of the second storage member 7 facing the upper discharge hole 45 may be a sloped surface 72 formed to be inclined upward.

In this case, the rear surface of the storage compartment S may be the front surface of the fan cover 41 . The second vertical separation distance H2 may be a height difference between the upper end 45a of the upper discharge hole 45 and the upper end 60 of the second accommodating member 7 .

The second horizontal separation distance D2 between the rear surface 71 of the second storage member 7 and the upper discharge hole 45 is the rear surface 61 of the first storage member 6 and the lower discharge hole 46 ) may be longer than the first horizontal separation distance D1 between them. Unlike the first accommodating member 6, since the second accommodating member 7 faces a part of the upper discharge hole 45 with respect to the horizontal direction, an additional separation distance for air circulation of the storage chamber S is required. Because. Accordingly, the length in the front-rear direction of the first accommodating member 6 may be longer than the length in the front-rear direction of the second accommodating member 7 .

The inner suction hole 44 may face between the first accommodating member 6 and the second accommodating member 7 . The inner suction hole 44 may not overlap the second accommodating member 7 in the horizontal direction. Accordingly, the air flow to the inner suction hole 44 is smoothed and the temperature of the storage compartment S is lowered, thereby improving the refrigeration performance of the refrigerator.

The vertical height of the second accommodating member 7 may be lower than the vertical height F1 of the first accommodating member. Due to this configuration, food having a high height, such as a bottle, can be accommodated in the first accommodating member 6 , and food having a relatively low height can be accommodated in the second accommodating member 7 .

The control unit 18a may receive and store the measured values of each sensor provided in the refrigerator. The controller 18a may control the thermoelectric module 3 , the cooling fan 4 , and the heat dissipation fan 5 . The control unit 18a may further control additional components as necessary.

For example, when the upper end of the heat dissipation cover 8 is spaced apart from the top cover 13 , the PCB cover 18 may cover the rear of the control unit 18a. Accordingly, it is possible to prevent the control unit 18a from being exposed to the rear of the main body 1 .

On the other hand, when the upper end of the heat dissipation cover 8 is in contact with the top cover 13, the control unit 18a is not exposed to the rear of the body 1 by the heat dissipation cover 8, so the PCB cover 18 is the control unit ( The upper side of 18a) may be covered, and the rear side may not be covered.

Meanwhile, the blocking member 85 may block the gap 86 between the heat dissipation fan 5 and the heat dissipation cover 8 . In more detail, the blocking member 85 may block the gap 86 between the shroud 51 of the heat dissipation fan 5 and the heat dissipation cover 8 .

When the gap 86 between the heat dissipation fan 5 and the heat dissipation cover 8 is not blocked by the blocking member 85 , the air sucked into the heat dissipation fan 5 through the outer suction hole 83 is blown by a heat sink. to be heated in the heat sink 33 , and some of the air heated in the heat sink 33 flows into the gap 86 between the shroud 51 and the heat dissipation cover 8 to the heat dissipation fan 5 . Re-suction can result in flow disturbances. Such flow disturbance may generate low-frequency tone noise, and the already heated air may be blown back to the heat sink 33 , thereby reducing the heat dissipation efficiency of the heat sink 33 .

The blocking member 85 prevents the recirculation phenomenon in which the air heated by the heat sink 33 flows into the gap 86 between the heat dissipation fan 5 and the heat dissipation cover 8 and is sucked into the heat dissipation fan 5 . can be prevented Accordingly, there is an advantage that noise generated by flow disturbance can be reduced, and the heat dissipation efficiency of the heat sink 33 can be increased.

In addition, as described above, the blocking member 85 may have a porous material. Accordingly, the blocking member 85 can effectively reduce vibration and noise generated by the driving itself of the heat dissipation fan 5 .

8 is a rear view of a refrigerator according to an embodiment of the present invention.

As shown, the outer suction hole 83 formed in the heat dissipation cover 8 may be formed in a plurality of perforated structures.

A plurality of outer suction holes 83 may be formed in the suction grill 82 . The outer suction hole 83 may be formed in a circular shape.

Meanwhile, although not shown, the suction grill 82 may be a mesh composed of a plurality of wires 87 . The suction grill 82 may have a rectangular outer suction hole 83 formed between each wire 87 .

In the above-described embodiment, foreign substances such as fine dust in the external air may be introduced into the refrigerator through the outer suction hole 83 .

In addition, the refrigerator according to an embodiment of the present invention may be a relatively small side table refrigerator, and may not be installed so that the rear surface of the refrigerator is located on the wall of the kitchen or living room. That is, the installation space may appear in a variety of ways, such as near a sofa in the living room in an office or home, near a bed in a bedroom, or near a glass window.

For this reason, there is a high possibility that the rear of the refrigerator is exposed to the user, and the possibility that dust is discharged to the front of the refrigerator where the user is located for a long time is also increased.

In addition, when the refrigerator is positioned so that the rear surface of the refrigerator is adjacent to the curtain or blind, as air is sucked into the refrigerator, a part of the curtain or blind blocks the outer suction hole 83 may occur. In this case, the flow of air is not smooth, there is a risk of noise generation, and thermal efficiency may be lowered.

Therefore, it is necessary to prepare a method for preventing dust from entering and discharging, maintaining a clean rear surface of the refrigerator, and ensuring smooth air flow.

Hereinafter, a filter assembly that can be applied to an embodiment of the present invention will be described in detail.

9 illustrates a rear view of the refrigerator in which the filter assembly is mounted. 10 illustrates a rear view of the refrigerator in a state in which the filter assembly is moved in order to remove or clean the filter assembly. Features except for the filter assembly may be the same as or similar to those of the above-described embodiments.

In this embodiment, the filter assembly 100 is movably provided on the heat dissipation cover 8 and filters foreign substances from the air introduced into the refrigerator through the outer suction hole 83 .

The heat dissipation cover 8 may include a cover plate 81 having a cover through hole 81a (see FIG. 3 ) formed therein, and a suction grill 82 mounted on the cover plate 81 to cover the through hole. . The outer suction hole 83 may be formed in the suction grill 82 .

A plurality of suction holes 83 may be formed, and a plurality of suction holes may be regularly formed vertically and horizontally. The plurality of suction holes 83 may be formed in a grid shape, and the suction holes may have a rectangular shape.

The suction grill 82 may be formed through plastic injection, and thus it may be very easy to form a plurality of suction holes.

The filter assembly 100 may include filter units 120 and 130 for filtering foreign substances and a handle 110 connected to the filter unit. The filter units 120 and 130 are disposed between the plurality of suction holes 83 and the cover through-holes to filter foreign substances in the suctioned air.

To this end, the filter parts 120 and 130 may include a mesh 130 and a frame 130 for reinforcing the rigidity of the mesh. The frame 130 may be formed in a grid shape, and a mesh 130 may be provided for substantially the entire frame 130 .

The mesh 130 may be formed in a very dense mesh shape. Therefore, large foreign substances are primarily filtered by the outer suction hole 83 , and secondarily, fine foreign substances are filtered by the mesh 130 .

The filter parts 120 and 130 are preferably connected to the handle 110 . Specifically, it is preferable that the frame 130 is connected to the handle 110 . Therefore, it is preferable that the handle 110 and the filter unit are movable integrally. A user may hold the handle and manipulate the filter assembly to move.

Specifically, the handle is preferably formed to protrude rearward than the suction grill 82 while the filter assembly 100 is mounted on the heat dissipation cover 8 . In addition, the handle is preferably provided so as not to overlap the outer suction hole 83 back and forth in a state in which the filter assembly 100 is mounted on the heat dissipation cover 8 .

Accordingly, the flow of air introduced into the outer suction hole by the handle may not be disturbed. In addition, the handle 110 is positioned more rearward than the suction grill 82 . Therefore, even if the curtain or blind comes into contact with the handle 110 , the distance between the curtain or the blind and the suction grill 82 can be maintained by the handle 110 .

In other words, the handle can prevent the possibility that a curtain or blind can completely cover the plane of the suction grill 82 in advance. This is because, even when the handle 110 comes into contact with the curtain and the blind, a gap through which air can flow is necessarily generated between the lower portion of the handle 110 and both sides of the handle and the curtain or blind.

Therefore, it is possible to prevent easy manipulation of the filter assembly and clogging of the suction grill 82 through the handle 110 in advance.

On the other hand, when the rear surface of the refrigerator is in close contact with the wall surface as much as possible, the distance between the wall surface and the suction grill 82 may be very narrow. In this case, smooth inflow of air may not occur. Accordingly, it can be said that the handle 110 is formed to form or maintain a minimum gap between the suction grill 82 and the wall surface. That is, the distance at which the refrigerator can be in close contact with the wall is limited. Therefore, smooth air flow is possible through the handle.

It is necessary to minimize damage to the handle or damage to the wall caused by the handle. Therefore, the handle is preferably formed of a plastic material. And the front surface of the handle is preferably formed to have a vertical surface. The front surface of the handle preferably has a long shape left and right, and the vertical width is preferably larger than the size of the suction hole. Through this, it may be possible to smoothly introduce air when in contact with a wall, curtain, or blinder.

Meanwhile, between the cover plate 81 and the suction grill 82, it is preferable that an opening 88 that is movable while the filter assembly enters and exits is formed.

The opening 88 is preferably formed on the upper portion of the suction grill 82 . In addition, the handle 110 is preferably located on the upper portion of the filter unit (120, 130).

Accordingly, the filter assembly, particularly the filter unit, can be moved up and down through the opening 88 .

Here, the filter units 120 and 130 have a relatively small front and rear thickness. Accordingly, the opening may be formed to correspond to the shape and size of the filter unit. However, it is preferable to allow entry and exit of the filter unit, but not allow entry and exit of the handle. That is, when the handle is caught in the opening 88, it can be said that the mounting of the filter assembly is completed.

On the other hand, it is preferable that the filter assembly can be firmly fixed when mounted. First, it can be said that the filter assembly is provided to move up and down for such fixing. In addition, for this fixing, a lower part of the handle may be inserted into the opening. That is, by fitting the lower part of the handle to the opening, mounting and fixing of the filter assembly may be completed.

After the filter assembly is mounted, a left and right external force may be applied to the handle. In the process of installing the refrigerator, such an external force may be applied. At this time, the external force applied to the handle may be distributed to the suction grill 82 due to the shape of the opening. That is, the external force transmission to the filter unit can be minimized. Accordingly, it is also possible to safely protect the filter unit.

As described above, the cover plate 81 has a raised portion 84 raised to the rear, and a cover through hole 81a is formed on the raised portion. That is, it can be said that the suction grill 82 is mounted to cover the raised portion 84 .

As a result, the suction grill 82 and the opening 88 may be rearwardly spaced apart from other portions of the cover plate except for the raised portion 84 . In addition, the rear surface of the handle may face the raised portion while the filter assembly is mounted on the heat dissipation cover 8 .

Accordingly, the entire suction grill 82 and the filter assembly 100 may be located inside the raised portion 84 . Accordingly, the suction grill and filter assembly can be more stably fixed to the heat dissipation cover (8).

In addition, when the handle 110 is moved upward, a front and rear gap is generated between the rear surface of the handle and the cover plate 81 . This is because the handle is disengaged from the raised portion 84 as it moves upward.

The filter unit may be formed of an elastic material. Accordingly, when the handle 110 is moved upward, the rear surface of the handle 110 may have an area with the cover plate. That is, it is preferable that the filter part is elastically deformed so that the handle is moved to the rear while moving upward. Accordingly, the user can move the handle upward while bringing the handle into contact with the cover plate. Likewise, the user may move the handle downward while bringing the handle into contact with the cover plate.

This makes mounting, moving and dismounting of the filter assembly very convenient.
