Detailed Description

The present invention will be described in more detail with reference to the accompanying drawings and examples.

Hereinafter, preferred embodiments of a refrigerator according to the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or corresponding portions are denoted by the same reference numerals, and redundant description is omitted.

Fig. 1 is a side view showing a refrigerating chamber portion of a refrigerator according to the present invention. Fig. 2 is a front view showing a refrigerating chamber portion of the refrigerator according to the present invention.

The refrigerator 100 shown in fig. 1 includes a refrigerating compartment 10; a single-row evaporator 1 provided at the rear of the refrigerating compartment 10 and refrigerating the refrigerating compartment 10; and a centrifugal fan 2 which is provided above the evaporator 1 and sucks air from the evaporator 1. The refrigerating compartment 10 has a plurality of air inlets 3 at an upper portion thereof and a plurality of return air inlets 4 at a lower portion thereof. Air cooled by the evaporator 1 is sucked by the centrifugal fan 2 and blown upwards, and then is sent into the refrigerating chamber through each level of air inlets 3 in the air cavity of the refrigerating chamber; then flows into the evaporation chamber from the bottom air return inlet 4 to be cooled, thereby forming an air path circulation.

As shown in fig. 1 and 2, the refrigerating compartment 10 has, for example, 5-layer structures, i.e., a first layer structure 101, a second layer structure 102, a 3 rd layer structure 103, a fourth layer structure 104, and a fifth layer structure 105. The first layer structure 101 is the uppermost layer structure of the refrigerator compartment 100. Each layer 101-105 is separated by a shelf or a partition plate, and the heights of each layer 101-105 can be approximately the same or set to different heights according to requirements.

The first level structure 101 may be a level at the same height as the overhead compressor of the refrigerator 100. At least one intake vent 31 of the plurality of intake vents 3 is provided in the first floor structure 101, i.e., the intake vent 31 overlaps with the machine compartment of the refrigerator 100 as viewed from the front-rear direction of the refrigerator 100. The air inlet 31 may communicate with the evaporation chamber through an air passage duct 110 embedded in an inner container (foaming layer) of the refrigerator 100. Here, the evaporation chamber is a space including the evaporator 1 and the centrifugal fan 2. The air duct 110 passes around the bottom of the machine room from below from the centrifugal fan 2, and then is bent at the first layer 101 near the refrigerating compartment 10, continues to extend in the vertical direction, and communicates with the air inlet 31 when extending to near the top of the refrigerator. Further, the air inlets provided to the first floor structure 101 are asymmetrically designed in the left-right direction of the refrigerator 100, for example, according to the rotation direction of the centrifugal fan 2, that is, the air inlets 31 are offset in the left-right direction of the refrigerator. Specifically, as shown in fig. 2, if the wind blown out from the centrifugal fan 2 rotates counterclockwise when viewed from the front of the refrigerator 100, the wind inlet provided in the first level structure 101 is provided, for example, at a position to the left with respect to the center. Similarly, if the wind blown out from the centrifugal fan 2 rotates clockwise when viewed from the front of the refrigerator 100, the wind inlet provided in the first level structure 101 is provided, for example, at a position on the right with respect to the center. With this configuration, the air generated by centrifugal fan 2 can be uniformly supplied into refrigerating compartment 10, and the temperature in refrigerating compartment 10 can be made more uniform. In addition, since the air path duct 110 of the topmost air inlet 31 is buried in the warehouse, the front air path cover 111 has a simple shape and a beautiful appearance.

Further, a baffle 311 is provided on the downstream side of the intake vent 31. Here, the downstream side means the downstream side in the flow direction of the cold air passing through the evaporator 1. According to such a configuration, the air flow generated by the centrifugal fan 2 can be guided in a desired direction, for example, the guide plate is provided obliquely upward, so that the cold air is prevented from directly blowing to the food, the temperature in the refrigerating chamber 10 is made more uniform, and the cold air is not directly blown to the food and is not locally frozen.

The second layer structure 102, the 3 rd layer structure 103, and the fourth layer structure 104 are layers located at the middle portion of the refrigerating compartment 10.

The second layer structure 102 is provided at the same height as the centrifugal fan 2, for example. Other intake vents 32, 33 of the plurality of intake vents 3 may be disposed in the second layer structure 102. These air intakes 32, 33 are provided at both ends of the refrigerator 100 in the left-right direction, for example. In addition, the wind channel of one of the plurality of wind inlets 3 provided in the second layer structure 102 may be formed to be bent according to the rotation direction of the centrifugal fan 2. Specifically, if the wind blown out from the centrifugal fan 2 rotates counterclockwise when viewed from the front of the refrigerator 100, the wind path of the wind inlet provided at the left side of the second layer structure 102 with respect to the center may be formed to be bent, for example. The air duct provided in the air inlet on the right side of the second layer structure 102 with respect to the center may be formed, for example, to be bent, if the air blown from the centrifugal fan 2 rotates clockwise when viewed from the front of the refrigerator 100. Accordingly, since the direction of the air blown out from the centrifugal fan 2 is different on both sides of the centrifugal fan 2, the air generated from the centrifugal fan 2 can be uniformly supplied into the refrigerating compartment 10 by such an arrangement, and the temperature in the refrigerating compartment 10 can be made more uniform.

The third layer structure 103 is provided at the same height as the evaporator 1, for example. The third layer structure 103 and the evaporator 1 can be insulated by a thicker foamed layer. Another intake vent 34 of the plurality of intake vents 3 may be disposed in the third level structure 103. Further, the intake vent 34 may be provided at the left or right side of the refrigerator according to the rotation direction of the centrifugal fan 2. Specifically, if the wind blown out from the centrifugal fan 2 rotates counterclockwise as viewed from the front of the refrigerator 100, the wind inlet 34 may be provided at the left side of the refrigerator. Also, if the wind blown from the centrifugal fan 2 rotates clockwise as viewed from the front of the refrigerator 100, the wind inlet 34 may be provided at the right side of the refrigerator.

The fourth layer structure 104 is, for example, disposed at a lower level than the evaporator 1. A plurality of air returns 41, 42, 43 may be provided to the fourth layer structure 104. Specifically, the plurality of air returns 41, 42, 43 may be provided at the bottom and both the left and right sides of the fourth layer structure 104. The area opposite the fourth layer structure 104 in the front-rear direction of the refrigerator, i.e., the area below the evaporator 1, may be a return air pre-cooling area 140. Air flowing through the refrigeration compartment 10 flows from the return air inlets 4 at the bottom and sides of the refrigeration compartment 10 into the return air pre-cooling zone 140. With this configuration, the evaporator 1 is located away from the return air inlet of the refrigerating compartment, and freezing due to an excessively low temperature of the return air can be prevented.

The fifth layer structure 105 is, for example, a thermostatic chamber, which can be set to a temperature slightly higher than the temperatures of the first to fourth layer structures 101 to 104, and can store vegetables, for example.

The air path circulation of the refrigerator 100 will be described below with reference to fig. 1 and 2. As shown in fig. 1 and 2, the centrifugal fan 2 is vertically disposed above the evaporator 1, the cold air after heat exchange by the evaporator 1 is sucked into the air outlet chamber by the centrifugal fan 2, and is sent into the refrigerating chamber by the top of the air outlet chamber and the air inlets 3 at both sides, and the return air enters the return air pre-cooling zone 140 through the bottom of the fourth layer structure 104 of the refrigerating chamber 10 and the return air inlets 4 at both sides to be fully stirred (mixed) and then enters the evaporator to exchange heat with the evaporator 1.

Fig. 3 is a cross-sectional view of the refrigerator of the present invention shown in fig. 1, viewed from the W-W arrow. Fig. 3 shows an internal structure of a machine room (compressor room). The machine room includes, for example: a compressor for compressing the refrigerant; a fan assembly 302 for forcibly dissipating heat from the entire machine room; and a condenser 303. The air-path duct 110 of the topmost air inlet 31 is disposed below the fan assembly 302 and located in the foam layer W1. According to this configuration, since the air-passage duct 110 and the compressor 301 are arranged in a staggered manner, it is possible to avoid a loss of cooling capacity and condensation in the compressor room due to an excessively thin foam layer around the air-passage duct. Since the fan assembly 302 is relatively small, there is a large adjustment space, the air path duct 110 can be secured by increasing the thickness of the foam layer at the lower portion of the fan assembly 302, and the air path duct 110 can be disposed below the fan assembly so as to avoid the mutual influence (large temperature difference) between the compressor and the condenser. Also, in this example, the intake vent 31 is disposed to the left with respect to the center of the refrigerator according to the position of the fan assembly 302.

Fig. 4 is an enlarged view showing a portion a of the refrigerator of the present invention shown in fig. 2. As shown in fig. 4, the air inlet 31 at the top is provided with air guiding ribs a1, a 2. By providing the air guide ribs, the intervals of the air guide ribs a1, a2 of the air inlet 31 at the topmost part are not uniformly distributed in the left and right direction of the refrigerator. The flow guiding ribs can be arranged to have a certain angle. Because the air inlet 31 is arranged on the left side, the left air guide rib a1 can be arranged into 1 piece, the air flow cross section is smaller, and the right air guide rib a2 is arranged into three pieces, the cross section is larger. The uniformity of air outlet can be ensured by properly adjusting the proportion of the air outlet area towards the left, middle and right directions. This makes it possible to uniformly send the air generated by centrifugal fan 2 into refrigerating compartment 10, thereby making the temperature in refrigerating compartment 10 more uniform.

According to the utility model discloses a refrigerator owing to adopt single-row evaporimeter and centrifugal fan, wholly can promote the evaporimeter configuration height by a wide margin, and the wind path route shortens, and on-way resistance loss reduces.

In addition, the air path of the air inlet 31 at the topmost part is buried in the foaming layer of the box body, so that the use volume of the topmost layer is increased. And, the air inlet 31 at the top is provided with a flow guiding rib, and the front part of the air inlet is provided with a flow guiding plate. The left and right air quantity of the air inlet 31 at the top is uniform, and the local freezing of food caused by the direct blowing of the air inlet is avoided. In addition, because the air path of the topmost air inlet 31 is buried in the warehouse, the front air path cover plate is simple in shape, and the appearance and taste are improved.

While the present invention has been described in detail in connection with the drawings and the examples, it is to be understood that the above description is not intended to limit the present invention in any way. For example, in the above description, the structure of the refrigerating chamber 10 of the refrigerator 100 is described as the first layer structure 101, the second layer structure 102, the 3 rd layer structure 103, the fourth layer structure 104, and the fifth layer structure 105. But is not limited thereto, the refrigerating chamber 10 of the refrigerator 100 may have a structure of any layer.

The present invention may be modified and varied as necessary by those skilled in the art without departing from the true spirit and scope of the invention, and all such modifications and variations are intended to be included within the scope of the invention.
