Description

Technical Field

[0001] The present invention relates to a refrigerator, and in particular to a refrigerator that can be arranged in a system kitchen or the like. Background Art

[0002] With the prevalence of integrated kitchens, refrigerators installed within them have also become practical. Due to limited space, these refrigerators often use direct-cooling technology. These refrigerators lack a circulating fan and instead utilize an evaporator to directly cool food and other items. However, automatic defrosting is difficult in direct-cooling refrigerators, requiring items to be removed from the inner compartment during defrosting.

[0003] Therefore, a refrigerator for a kitchen has been proposed. This refrigerator, unlike a conventional refrigerator, is not a direct-cooling type, but rather features an evaporator and a circulation fan on the back side. However, to accommodate this in a kitchen, the depth of the refrigerator must be reduced, which limits the depth of the inner compartment. This refrigerator, in order to secure space for the evaporator and circulation fan, further reduces the limited depth of the inner compartment, creating issues with storage capacity within the inner compartment.

[0004] Therefore, in order to ensure the depth dimension of the inner box, a refrigerator is proposed in which the evaporator and the circulation fan are arranged in the space between the upper inner box and the lower inner box (for example, refer to Patent Document 1 - Japanese Utility Model Publication No. 5-90286).

[0005] However, the refrigerator described in Patent Document 1 requires a large receiving dish to be placed throughout the area below the horizontally positioned evaporator to collect droplets produced during defrosting. To accommodate it within a kitchen, the refrigerator's height must also be reduced, placing constraints on the height of the inner compartment. In order to secure space for the receiving dish in addition to the evaporator, this refrigerator must further reduce the limited height of the inner compartment, creating issues with storage capacity within the inner compartment.

[0006] As described above, in conventional refrigerators (including the refrigerator described in Citation 1), the storage capacity in the inner box cannot be efficiently ensured due to the influence of the evaporator. Summary of the Invention

[0007] Therefore, an object of the present invention is to solve the above-mentioned problem and provide a refrigerator capable of efficiently arranging an evaporator to efficiently ensure the storage capacity in the inner box.

[0008] The refrigerator of the present invention comprises:

[0009] outer box;

[0010] a first inner box, disposed in the outer box and used for storing items;

[0011] a second inner box, arranged side by side with the first inner box in the outer box, the second inner box being placed to the side of the first inner box for storing articles;

[0012] an air duct provided in a space between the first inner box and the second inner box arranged side by side;

[0013] an evaporator, disposed in the air duct;

[0014] a circulation fan, arranged in the air duct;

[0015] a first upper opening, disposed on an upper side of the air duct and communicating with the first inner box;

[0016] a second upper opening, disposed on an upper side of the air duct and communicating with the second inner box; and

[0017] a first lower opening, disposed at a lower side of the air duct and communicating with the first inner box;

[0018] a second lower opening, disposed on the lower side of the air duct and communicating with the second inner box;

[0019] The circulation fan is used to make the gas flow from bottom to top in the air duct. After passing through the evaporator, the gas is separated into left and right, flows into the first inner box through the first upper opening, and flows into the second inner box through the second upper opening. After flowing in each inner box, the gas returns to the air duct through the first lower opening and the second lower opening, forming a cold air circulation.

[0020] According to the present invention, since the evaporator is positioned between the two side-by-side inner boxes, it is not restricted by the inner box's front-to-back and vertical dimensions. The longitudinal placement of the evaporator also reduces the size of the receiving dish that collects droplets produced during defrosting. This allows for efficient evaporator placement, effectively ensuring the inner box's storage capacity.

[0021] In addition, since the air duct where the evaporator is installed is surrounded by the inner box, heat leakage can be reduced and high thermal efficiency can be obtained. In addition, by making the space between the inner boxes into the air duct, the air duct can be formed with a very simple structure.

[0022] Furthermore, in the refrigerator of the present invention,

[0023] The circulation fan is disposed above the evaporator and discharges gas upward along the air duct. The discharged gas is separated left and right along a guide surface on an upper surface of the air duct and flows toward the first upper opening and the second upper opening.

[0024] According to the present invention, the circulating fan can be used to discharge air upward, where it is separated left and right along the guide surface of the upper surface of the air duct, and flows into the first and second inner boxes through the first and second upper openings. Thus, a single circulating fan can efficiently supply cool air to both inner boxes.

[0025] Furthermore, in the refrigerator of the present invention,

[0026] A plurality of partitions are provided in at least one of the first inner box and the second inner box to divide the inner space into upper and lower parts.

[0027] The interior of the partition is hollow,

[0028] The upper partition plate is provided with a ventilation hole communicating with the upper and lower parts at one end portion in the left-right direction, and the lower shelf plate is provided with a ventilation hole at the other end portion in the left-right direction.

[0029] According to the present invention, when the interior space is divided by multiple partitions, the partitions are hollow, and ventilation openings connecting the upper and lower partitions are located at opposite ends. Consequently, air flowing into the inner box from the upper opening flows in a zigzag pattern along the partitions within the inner box while simultaneously flowing downward, thereby effectively cooling items placed on the partitions.

[0030] Furthermore, in the refrigerator of the present invention,

[0031] A machine room equipped with a compressor is provided on the lower side of one of the first inner box and the second inner box. The height of the lower surface of the one inner box is higher than the height of the lower surface of the other inner box. An evaporating dish and an evaporative condenser are provided on the lower side of the other inner box.

[0032] According to the present invention, the machine room, which houses components requiring height, such as a compressor, is located beneath only one inner box. This ensures sufficient storage capacity within the other inner box. Furthermore, by arranging the evaporating dish and evaporative condenser, which require no height, in the space below the other inner box, efficient configuration is achieved by utilizing dead space.

[0033] Furthermore, in the refrigerator of the present invention,

[0034] A cooling fan is provided in the machine room, through which external air flows from the front side into the lower side of the other inner box, flows from the lower side of the other inner box into the machine room on the lower side of the one inner box, and is discharged from the machine room to the front side.

[0035] According to the present invention, external air is sucked in from the front side of the lower portion of the refrigerator to cool the heat-generating components, and the gas with increased temperature is discharged from the front side of the lower portion of the refrigerator. Therefore, even if the refrigerator is set in an integrated kitchen, efficient cooling can be achieved without causing thermal impact on surrounding components.

[0036] As described above, the present invention can provide a refrigerator capable of efficiently installing an evaporator to efficiently ensure the storage capacity in the inner box. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Hereinafter, embodiments for implementing the present invention will be described with reference to the accompanying drawings. The following description is for embodying the technical concept of the present invention, and the present invention is not limited to the following description unless otherwise specified.

[0042] In the drawings, components with the same function are sometimes designated by the same reference numerals. For clarity, the sizes and positional relationships of components shown in the drawings are sometimes exaggerated. In this specification, the refrigerator is shown as being placed on a horizontal surface, with the door side being the front side and the side opposite it being the rear side. Arrows in the drawings indicate up, down, front, back, left, and right directions.

[0043] (Refrigerator according to one embodiment of the present invention)

[0044] Figure 1 It is a perspective view showing the outer appearance of a refrigerator 2 according to one embodiment of the present invention. Figure 2 It shows Figure 1 A side view of the internal structure of the refrigerator 2 is shown. Figure 3 It shows Figure 2 The internal structure shown is a three-dimensional view (especially the partitions 12, 12', the ventilation holes 16 set on the bottom plates 14A and 14B, and the bottom plate air duct inlet 18).

[0045] A refrigerator 2 according to one embodiment of the present invention has a first inner box 10A and a second inner box 10B arranged side by side inside an outer box (frame) 4. Food, beverages, and other storage items are stored inside the first inner box 10A and the second inner box 10B. A door 6A for opening and closing the first inner box 10A and a door 6B for opening and closing the second inner box 10B are provided in the front opening of the outer box 4. The doors 6A and 6B have a rotation axis extending up and down on the outside of the first inner box 10A and the second inner box 10B arranged side by side, and are so-called double doors (also called French doors). Therefore, the partition portion between the first inner box 10A and the second inner box 10B usually becomes a dead space.

[0046] In the refrigerator 2 of this embodiment, a gas duct 20 is provided in the dead space formed between the first inner box 10A and the second inner box 10B. An evaporator 22 and a circulation fan 24 are provided within this duct 20. A first upper opening 26A communicating with the first inner box 10A and a second upper opening 26B communicating with the second inner box 10B are provided on the upper side of the duct 20. In this embodiment, a duct portion 20B extending left and right is provided on the upper side of the duct 20. The first upper opening 26A and the second upper opening 26B are provided at the left and right ends of the duct portion 20B.

[0047] With this structure, the depth and height of the first inner box 10A and the second inner box 10B are not restricted by the space for installing the evaporator 22 and the circulation fan 24. Therefore, even if the refrigerator 2 of this embodiment is installed in a location with limited depth and height (such as inside a kitchen), storage space can be efficiently ensured.

[0048] In a kitchen, since the horizontal dimension can be relatively large compared to the depth and height, it is expected that sufficient storage capacity can be achieved by arranging the first inner box 10A and the second inner box 10B side by side. If the width is large and the height and depth dimensions are limited, the refrigerator 2 of this embodiment can be installed not only in a kitchen but also in the installation space of a small furniture piece.

[0049] Furthermore, the space between the first inner box 10A and the second inner box 10B, which was previously dead space, is now effectively utilized to provide an air duct 20, within which the evaporator 22 and the circulation fan 24 are located. This allows for an efficient configuration. This configuration can be applied to any side-by-side refrigerator with a partition.

[0050] In the refrigerator 2 of this embodiment, the compressor 32, condenser, and evaporator 22 are fluidically connected, and refrigerant circulates within the evaporator 22, forming a cooling cycle. The evaporator 22 cools the gas flowing within the air duct 20 through heat exchange with the refrigerant. The compressor 32 compresses the refrigerant vaporized by the evaporator 22, causing it to flow into the condenser, where it liquefies and returns to the evaporator 22.

[0051] The following describes the flow of gas within the air duct 20 of the refrigerator 2 of this embodiment. A circulation fan 24 is disposed above the evaporator 22 within the air duct 20, drawing gas from the bottom and discharging it to the top. Therefore, the circulation fan 24 causes the gas to flow from the bottom to the top within the air duct 20, being cooled as it passes through the evaporator 22. The cold air that has passed through the evaporator 22 is discharged by the circulation fan 24, causing the cold air to strike the upper surface of the air duct 20, where it flows separately to the left and right, respectively, toward the first upper opening 26A and the second upper opening 26B. At this point, a guide surface 20A is formed on the upper surface of the air duct 20, comprising a smooth curved surface with a central protrusion. The cold air flows smoothly and roughly equally to the left and right along the guide surface 20A. However, this is not limiting, and depending on the shape of the guide surface 20A, the flow rates of the gas flowing separately to the left and right can also be made to have different proportions.

[0052] As described above, according to this embodiment, air is discharged upward by circulation fan 24. The discharged air is divided and flows left and right along guide surface 20A on the upper surface of air duct 20, then flows into first inner box 10A and second inner box 10B through first upper opening 26A and second upper opening 26B. Thus, a single circulation fan 22 can efficiently supply cool air to both inner boxes 10A and 10B.

[0053] The gas flowing into the first inner box 10A through the first upper opening 26A flows through the first inner box 10A, cooling the items stored therein, and then returns to the air duct 20 through the first lower opening 28A below. The gas flowing into the second inner box 10B through the second upper opening 26B flows through the second inner box 10B, cooling the items stored therein, and then returns to the air duct 20 through the second lower opening 28B below. The returned gas is again sucked in by the circulation fan 24, forming a series of cooling cycles. This allows the interiors of the first inner box 10A and the second inner box 10B to function as a refrigerator and a freezer respectively. The flow of gas in the first inner box 10A and the second inner box 10B will be described in detail later.

[0054] In this embodiment, the machine room 30 in which the compressor 32 is provided is located on the lower side of the first inner box 10A. The machine room 30 is provided only on the lower side of the first inner box 10A, and the machine room 30 is provided with relatively large components constituting the cooling cycle. Therefore, the height of the lower surface of the first inner box 10A is higher than the height of the lower surface of the second inner box 10B. As a result, the height dimension of the storage area of ​​the second inner box 10B can be made larger, thereby obtaining sufficient storage capacity. However, this arrangement is not limited to the above, and there may also be a case where, on the contrary, the machine room 30 is provided only on the lower side of the second inner box 10B, and the height of the lower surface of the second inner box 10B is higher than the height of the lower surface of the first inner box 10A.

[0055] As described above, in refrigerator 2 of this embodiment, since evaporator 22 is positioned between the first and second inner boxes 10A, 10B, which are arranged side by side, the evaporator 22 is not restricted by the longitudinal and vertical dimensions of the inner boxes 10A, 10B. The longitudinal arrangement of evaporator 22 also reduces the size of the receiving dish that collects droplets produced during defrosting. This allows for efficient placement of evaporator 22, effectively ensuring sufficient storage capacity within the inner boxes 10A, 10B.

[0056] Furthermore, since the air duct 20 in which the evaporator 22 is installed is surrounded by the inner boxes 10A and 10B, heat leakage can be reduced, thereby achieving high thermal efficiency. In addition, by using the space between the inner boxes 10A and 10B as the air duct 20, the air duct can be formed with a very simple structure.

[0057] (Gas flow in inner box)

[0058] Next, refer to Figure 2 and Figure 3 , illustrating the gas flow in the first inner box 10A and the second inner box 10B. Figure 2 in Figure 3 In the figure, the flow of gas is schematically represented by dashed arrows.

[0059] <First inner box>

[0060] The first inner box 10A has no partitions dividing the interior space, but a flat bottom plate 14A is provided at the bottom. This allows the entire height of the first inner box 10A to be used for storing items, making it suitable for storing bottles of wine or drinking water, for example.

[0061] The interior of the bottom plate 14A is hollow, and a bottom plate air duct inlet 18 is provided at the left end. This bottom plate air duct inlet 18 allows air flowing through the first inner box 10A to flow into the interior of the bottom plate 14A. A first lower opening 28A is provided at the right end of the bottom plate 14A, which allows air flowing through the bottom plate 14A to flow out into the air duct 20.

[0062] Thus, air flowing into first inner box 10A from first upper opening 26A is guided along the inner wall of first inner box 10A, flowing from the upper side to the lower side, cooling the contents therein. It then flows from bottom plate duct inlet 18 into bottom plate 14A, flows from left to right within bottom plate 14A, and flows into air duct 20 from first lower opening 28A. The air flowing in air duct 20 is then drawn upward by the suction force of circulation fan 22, passing through evaporator 22 again.

[0063] The bottom plate 14A is hollowed to form a gas duct. Thus, simply by providing the bottom plate 14A at the bottom of the first inner box 10A, the gas in the first inner box 10A can be easily guided into the duct 20 with a simple structure.

[0064] <Second inner box>

[0065] On the other hand, in the second inner box 10B, two partitions 12 and 12' are provided to divide the internal space into upper and lower parts. The partitions 12 and 12' extend to the inner shape limit of the second inner box 10B in the front-to-back direction, thereby obtaining a larger storage space. The interior of these partitions 12 and 12' is also hollow. A bottom plate 14B is provided at the bottom. The bottom plate 14B has an L-shaped side shape and is hollow inside. The reason why the bottom plate 14B has an L-shaped side shape instead of a flat plate is that the position of the bottom of the second inner box 10B provided with the bottom plate 14B is lower than the bottom of the air duct 20 located on the upper side of the machine room 30, and therefore an air duct is provided to connect the height difference up and down.

[0066] A vent 16 for vertical communication is provided at the right end of the upper partition 12. A vent 16 for vertical communication is provided at the opposite left end of the lower partition 12'. A bottom plate air duct inlet 18 is provided at the right end of the bottom plate 14B. This allows air flowing through the second inner box 10B to flow into the interior of the bottom plate 14B. A second lower opening 28B is provided at the left end of the bottom plate 14B. This second lower opening 28B allows air flowing through the bottom plate 14B to flow out into the air duct 20.

[0067] Thus, the air flowing into the second inner box 10B from the second upper opening 26B flows from left to right along the upper surface of the upper partition 12. It then flows through the vents 16 into the lower space partitioned by the partition 12. The air then flows from right to left along the lower surface of the upper partition 12 and downward. It then flows through the vents 16 provided in the lower partition 12' into the lower space partitioned by the lower partition 12'. The air then flows from left to right along the lower surface of the lower partition 12' and downward. It then flows through the bottom duct inlet 18 into the bottom plate 14A, flowing from right to left within the bottom plate 14A and further from bottom to top, before flowing into the air duct 20 through the second lower opening 28B. The air flowing within the air duct 20 is then drawn upward by the suction force of the circulation fan 22, passing through the evaporator 22 again.

[0068] This gas flow allows efficient cooling of the stored items placed on the partition plates 12 and 12 ′ and the bottom plate 14B.

[0069] Here, the number of partitions 12 and 12' is not limited to two, and any number of partitions more than two can be set. The left and right positions of the vents 16 can also be arbitrarily set according to the configuration in the second inner box 10B. In the upper partition 12, preferably, the vent 16 is provided at the end opposite to the position of the second upper opening 26B, and the upper partition 12 guides the gas flowing in from the second upper opening 26B. In the lower partition 12' arranged below it, preferably, the vent 16 is provided at the end opposite to the end where the vent 16 of the upper partition 12 is provided. That is, preferably, in the upper partition 12, a vent 16 connecting the upper and lower ends is provided at one end in the left and right directions, and in the lower partition 12', a vent 16 is provided at the other end in the left and right directions.

[0070] As described above, according to this embodiment, when the internal space is divided by multiple partitions 12, 12', the interiors of the partitions 12, 12' are hollow, and the vents 16 connecting the upper and lower partitions 12, 12' are provided at opposite ends. Consequently, air flowing in through the second upper opening 26B flows in a zigzag pattern along the partitions 12, 12' within the second inner box 10B, while also flowing downward. This allows for sufficient cooling of items placed on the partitions 12, 12'.

[0071] The bottom plate 14B also has a bottom plate air duct inlet 18 at the end opposite to the vent 16 provided in the upper partition 12'. This allows air to flow in a zigzag pattern in the second inner box 10B, effectively cooling the items placed on the bottom plate 14B.

[0072] Like the bottom plate 14A, the bottom plate 14B is hollowed to form a gas duct. Thus, simply by providing the bottom plate 14B at the bottom of the second inner box 10B, the gas in the second inner box 10B can be easily guided into the duct 20 with a simple structure.

[0073] (Gas flow under the inner box)

[0074] Figure 4 10A and 10B are perspective views showing the structure of the lower side of the first and second inner boxes 10A and 10B. Figure 4 In the figure, the gas flow below the first inner box 10A and the second inner box 10B is also shown by dotted lines. As described above, the machine room 30 with the compressor 32 is located below the first inner box 10A, and the bottom surface of the first inner box 10A is higher than the bottom surface of the second inner box 10B.

[0075] Thus, sufficient storage capacity can be ensured in the second inner box 10B, and the space under the second inner box 10B, which is usually a dead space, can be effectively utilized. Figure 4 As shown, an evaporation dish 36 and an evaporation condenser 34 that do not require height are provided. Here, in order to illustrate the evaporation condenser 34, the evaporation dish 36 is shown with a virtual line.

[0076] The evaporating dish 36 is connected to the receiving dish via a drain pipe. The receiving dish is located below the evaporator 22. Water generated during the defrosting process flows into the receiving dish. Below the evaporator 22 is an evaporative condenser 34. High-temperature refrigerant discharged from the compressor 32 flows through the evaporative condenser 34. The water accumulated in the evaporator 22 is heated by the evaporative condenser 34, promoting evaporation.

[0077] As described above, according to this embodiment, the machinery compartment 30 is located only below the first inner box 10A. This compartment houses the compressor 32 and other components requiring height. This ensures sufficient storage capacity within the second inner box 10B. Furthermore, by placing the evaporating dish 36 and evaporative condenser 34, which do not require height, in the space below the second inner box 10B, efficient configuration is achieved by utilizing dead space.

[0078] (Structure of the lower side of the inner box)

[0079] like Figure 4As shown, in the machine chamber 30, a cooling fan 40 is provided. By the cooling fan 40, external air flows from the front side into the lower side of the second inner tank 10B, from the lower side of the second inner tank 10B to the lower side of the first inner tank 10A in the machine chamber 30, and is discharged from the machine chamber 30 to the front side. By this gas flow, the high-temperature components, including the compressor 32, the condenser, can be effectively cooled. At this time, external air can be sucked from the front side of the lower part of the refrigerator 2, and the gas after temperature rise is discharged to the front side of the lower part of the refrigerator 2.

[0080] By this gas flow, even in the case where the refrigerator 2 is provided in the overall kitchen, efficient cooling can be achieved without thermal influence on the surrounding components.

[0081] Although the embodiments, modes of implementation of the present application are described, the disclosure can vary in the details of the structure, and the combination and order of the elements in the embodiments, modes of implementation can be changed without departing from the scope and idea of the claimed application.
