This disclosure relates to a refrigerator suitable for wine storage and the like.

Generally, in a refrigerator such as a wine cellar for storing and storing wine, the door has a substantially central portion made of a transparent plate such as glass so that the inside can be seen (see, for example, Patent Document 1).

FIG. 33 shows the door configuration of the wine cellar described in Patent Document 1. The door face material 101 has a window portion 102. The transparent plate 103 is disposed on the front surface of the door face material 101. The side support member 104 is attached to the side portion of the transparent plate 103. As shown in FIG. 33, the upper cap 105 and the lower cap 106 are disposed on the upper and lower portions of the door face material 101, the transparent plate 103, and the side support member 104. The door inner plate 107 is attached to the rear surfaces of the door face material 101 and the transparent plate 103.

The thus configured wine cellar with a door can be visually observed through the transparent plate 103, so it is easy to use.

However, in the conventional door configuration as described in Patent Document 1, in order to obtain a door with a transparent plate, in addition to the door face material 101 and the door inner plate 107, a side for fixing four pieces of the transparent plate 103 is used. The support member 104, the upper cap 105, and the lower cap 106 are required. Further, a gasket is attached to the door inner plate 107.

The conventional door configuration as described above requires a large number of parts, requires a large number of assembly steps, and increases the cost. Therefore, the wine storage tends to be expensive.

JP 2000-346540 A

This disclosure has been made in view of such a problem, and enables the provision of an inexpensive refrigerator by reducing the cost of the door configuration.

Specifically, a refrigerator according to an example of the present disclosure includes a refrigerator main body having a storage chamber therein, and a door that is supported by the refrigerator main body and opens and closes the opening of the storage chamber. The door includes a translucent central plate, an edge frame that holds the central plate, and a gasket that is disposed around a surface of the edge frame on the storage chamber side. The edge frame has an inner plate located on the storage chamber side with the door closed, and an outer plate that sandwiches and holds the central plate together with the inner plate. The inner plate has a recess around the surface on the storage chamber side. The gasket is held in the recess via a gasket holding member.

With such a configuration, the main parts for holding and fixing the central plate are only the outer plate and inner plate of the edge frame, so the number of components can be greatly reduced. In addition, since the outer plate and the inner plate can be manufactured by inexpensive injection molding, the component manufacturing cost can also be suppressed. Furthermore, a configuration for holding the gasket on the inner plate, which is difficult to form by injection molding, can be realized by mounting an extrudable gasket holding member on the inner plate. With such a configuration, the gasket holding member can be formed by inexpensive extrusion molding, and the number of parts is increased by one, but the cost increase due to the increase in the number of parts can be suppressed to a minimum. Therefore, with such a configuration, the cost can be significantly reduced by reducing the number of parts and the number of assembling steps, and reducing the part manufacturing cost.

Further, in the refrigerator according to an example of the present disclosure, the gasket holding member may have a convex portion that is held in the concave portion of the inner plate and a gasket holding concave portion that holds the gasket. In this case, a gasket removal prevention rib may be provided in the opening portion of the gasket holding recess.

With such a configuration, the gasket holding member can be securely attached and fixed to the concave portion of the inner plate of the edge frame. In addition, with such a configuration, the gasket can be firmly fixed and held in the gasket holding recess, so that the gasket can be prevented from falling off from the recess of the inner plate. With such a configuration, reliable sealing performance between the refrigerator body and the door can be ensured.

Further, in the refrigerator according to an example of the present disclosure, the refrigerator main body may include an outer box, an inner box that forms a wall surface of the storage chamber, and a hinge support member that supports the door on the refrigerator main body. In this case, the hinge support member may be configured not to be supported by the outer box. Moreover, the door may be comprised so that it may be supported by the hinge support member via an inner box.

Such a configuration can reliably prevent the door pivotally supported by the inner box from being inclined with respect to the outer box. Therefore, even if it is a refrigerator of the type which supports a door in an inner box, the quality can be improved and a yield can also be improved and cost reduction can be aimed at. Therefore, with such a configuration, the cost of the refrigerator can be significantly reduced along with the cost reduction effect of the door configuration.

Further, in the refrigerator according to the example of the present disclosure, the door covers the operation unit unit, the operation unit installation recess into which the operation unit unit is inserted, and at least the side opposite to the storage chamber side of the operation unit installation recess. You may further have the front board which has optical property. In this case, the operation portion installation recess may have an insertion opening that opens on the surface of the door on the storage chamber side. Moreover, the operation part unit may have the input part provided in the location facing an inner board, and the press piece provided in the both ends of the up-down direction of the operation part unit. The pressing piece may be configured to contact the inner wall of the recess for installing the operation unit or the cover that covers the insertion port and press the input unit against the surface of the front plate on the storage chamber side.

With such a configuration, it is possible to perform operations such as temperature setting by touching the outer surface of the front plate from the front side of the door, and it is possible to reliably press the electrode film against the front plate. Capacitance detection accuracy can be increased and operation quality can be improved.

Further, in the refrigerator according to an example of the present disclosure, the operation unit installation recess is provided between the contact surface on which the pressing piece provided on the lower end portion of the operation unit unit contacts, and the insertion port and the contact surface. And may have an inclined surface. In this case, the door may be configured to have a recess in a portion facing the inclined surface.

With such a configuration, the dead space generated behind the inclined surface can be effectively used as a gasket mounting space, and the operation unit and the gasket can be installed in an overlapping manner. As a result, the installation space can be reduced in size, and the central plate can be enlarged correspondingly to increase the visibility inside the refrigerator.

In the refrigerator according to the example of the present disclosure, the gasket provided above the door may be configured to be positioned between the upper edge of the opening of the storage chamber and the operation unit.

With such a configuration, the gasket is sealed between the storage chamber and the operation unit unit installation portion, and it is possible to prevent the cool air in the storage chamber from flowing to the operation unit unit installation rear surface portion and cooling it. With such a configuration, it is possible to prevent failures such as the occurrence of condensation due to excessive cooling of the operation unit, and a high-quality refrigerator can be obtained.

Further, in the refrigerator according to an example of the present disclosure, the center plate may have a multiple structure in which a heat insulating gas is enclosed. In this case, a heat insulating material may be provided on the outer peripheral portion of the central plate between the outer plate and the inner plate.

Such a configuration improves the heat insulation of the door and provides a refrigerator with good cooling performance.

The second attachment portion 76b is a surface that is provided below the first attachment portion 76a, is located on the front side from the front end of the first attachment portion 76, and extends in the vertical direction.

As shown in FIG. 27, the first mounting portion 76a is fixed to the ceiling surface of the outer box 96 with screws 77. The second mounting portion 76b abuts against the inner surface of the hinge bracket mounting flange surface 7b of the inner box 7. The hinge metal fitting flange surface 7 b is a part of the upper flange portion of the inner box 7. As shown in FIGS. 28 and 29, the hinge mounting bracket 76 is fixed to the second mounting portion 76b with screws 77 via the hinge mounting flange surface 7b.

With such a configuration, the outer box 96 and the inner box 7 are integrally connected by the hinge mounting bracket 76.

Further, as shown in FIGS. 30 and 31, the lower hinge 75b that pivotally supports the lower portion of the door 20 has the lower surface of the lower hinge 75b covered with a hinge cover 78. The hinge cover 78 includes a cover portion that covers the lower surface of the lower hinge 75b, and a lead wire regulating surface that is a surface substantially perpendicular to the cover portion and substantially parallel to the lower flange surface of the inner box 7. I have. The lead wire regulating surface is provided with a through hole 80 for regulating the movement range of the lead wire 79 described later.

As shown in FIG. 31, the lower hinge 75b includes a main body side fixing portion 751 fixed to the refrigerator main body 1 and a door side fixing portion 752 fixed to the door 20 side. A first link portion 754 is connected to the main body side fixing portion 751 via a main body side rotation shaft 753. A second link portion 756 is connected to the door side fixing portion 752 via a door side rotation shaft 755. The first link part 754 and the second link part 756 are connected via a moving rotation shaft 757. When the door 20 is closed, the first link portion 754 and the second link portion 756 overlap each other. In a state where the door 20 is opened, the door 20 protrudes from the refrigerator body 1 according to the lengths of the first link portion 754 and the second link portion 756. The upper hinge 75a has the same structure as the lower hinge 75b.

By using such a hinge, when the door 20 is closed, the side surface of the door 20 can be made to substantially coincide with the side surface of the refrigerator main body 1 as shown in FIG. Further, by using such a hinge, even when the door 20 is opened, the side surface of the door 20 is positioned on the front side of the refrigerator body 1 (inside the side surface of the refrigerator body 1) as shown in FIG. Can be made. With such a configuration, the door 20 can be opened and closed without interfering with equipment installed adjacent to the refrigerator, such as a dishwasher, even in an undercounter refrigerator built into a system kitchen or the like. .

The lead wire 79 (see FIG. 31) includes an operation display unit 23 (see FIGS. 8 and 16) provided on the upper portion of the door 20 and a control unit (not shown) provided on the back surface of the refrigerator body 1. It is an electric wire that is electrically connected. As shown in FIG. 32, the lead wire 79 from the operation display unit 23 is wired along the bottom surface of the door 20 to the lower hinge 75b (see FIG. 30). The lead wire 79 is drawn into the bottom surface of the refrigerator main body 1 through the through hole 80 (see FIG. 30) of the hinge cover, and is connected to a control unit (not shown).

The through-hole 80 is a first restricting portion that restricts the movement of the lead wire 79 in the left-right direction at the place where the lead wire 79 is pulled into the refrigerator body 1. The end of the through hole 80 on the center side of the refrigerator main body 1 is located on the opposite side of the central portion side of the refrigerator main body 1 from the moving rotation shaft 757 when the door 20 is closed (see FIG. 30). . Furthermore, the end of the through hole 80 on the center side of the refrigerator main body 1 is from the midpoint of the line segment connecting the movable rotating shaft 757 and the main body side fixing portion 751 (see FIG. 31) when the door 20 is closed. It is desirable that it is located on the opposite side to the central part side of the refrigerator body 1.

The end of the through hole 80 opposite to the central part side of the refrigerator main body 1 is located closer to the central side of the refrigerator main body 1 than the main body side rotation shaft 753.

Furthermore, the center of the through hole 80 in the left-right direction (the width direction of the refrigerator main body 1) is an extension line X of a line parallel to a virtual line passing through the center of the door 20 in the thickness direction when the door 20 is fully opened. It is desirable to be located above (see FIG. 30). In the present embodiment, an example in which the first restricting portion is provided in the hinge cover 78 as the through hole 80 is shown, but it may be provided directly in the refrigerator main body 1.

Further, the lead wire 79 drawn from the through hole 80 is held by a clip 81 (see FIG. 30) provided on the bottom surface of the refrigerator body 1. The clip 81 is a second restricting portion that restricts movement of the lead wire 79 in other directions without restricting movement of the lead wire 79 in a predetermined direction (for example, the Y direction in FIG. 30). The position of the clip 81 in the width direction of the refrigerator main body 1 is the center side of the refrigerator main body 1 with respect to the moving rotation shaft 757 in a state where the door 20 is closed. The position of the clip 81 in the depth direction of the refrigerator body 1 is on the back side of the refrigerator body 1 from the lower hinge 75b.

Next, the function and effect of the refrigerator 90 configured as described above will be described.

First, the flow of cold air will be explained. Cold air is generated in the cooling chamber 25 provided with the cooler 26 by driving the compressor 29. The cold air generated in the cooling chamber 25 is sucked into the cooling fan 27 and passes through the damper device 36 and from the first through-hole 43 and the second through-hole 44 to the first blowing air passage 47 and the second blowing air passage. 48.

The cold air supplied to the first blowing air passage 47 and the second blowing air passage 48 is supplied from the upper air outlet 51b and the lower air outlet 51a to the upper storage chamber 3 and the lower storage chamber 4, and the upper storage chamber 3 and The wine bottle in the lower storage chamber 4 is cooled.

The cool air after cooling the upper storage chamber 3 is sucked into the return air passage 50 from the upper return port 52b and the cool air after cooling the lower storage chamber 4 is returned from the lower return port 52a to the return air passage 50. And are collected into the cooling chamber 25 through the cold air return port 52.

The cool air supplied to the storage chambers 3 and 4 is individually controlled by the damper device 36 to cool the storage chambers 3 and 4 to a predetermined temperature.

Further, the cooling temperature of each of the storage rooms 3 and 4 can be set by a touch operation on the operation display unit 23 provided on the upper front surface of the door 20. Further, by displaying the temperature of each storage chamber 3, 4 on the operation display unit 23, the cooling temperature of each storage chamber 3, 4 can be notified to the user.

And since the wine bottle accommodated in each store room 3 and 4 can be visually observed through the center board 21, a user opens the door 20 and can take out quickly, without searching for a desired wine bottle. it can.

Here, the door 20 of the refrigerator 90 according to the present embodiment is configured such that the translucent central plate 21 is sandwiched and held between the outer plate 57 and the inner plate 56 of the frame-like edge frame 55. With such a configuration, the main parts for holding and fixing the central plate 21 are only the outer plate 57 and the inner plate 56 of the edge frame 55. Therefore, with this configuration, the number of parts can be greatly reduced. In addition, the outer plate 57 and the inner plate 56 can be manufactured by relatively inexpensive injection molding. Therefore, the part manufacturing cost can also be suppressed.

In addition, it is difficult to form the inner plate 56 by injection molding and simultaneously form the concave portion 60 projecting toward the outer plate 57 and the rib projecting from the side surface forming the depression of the concave portion 60 on the inner plate 56. . However, in this embodiment, the configuration for holding the gasket of the inner plate 56 that is difficult to form by injection molding is realized by mounting the gasket holding member 61 on the recess 60 formed at the same time as the inner plate molding by injection molding. ing.

Therefore, although the number of parts increases by one, the gasket holding member 61 is a linear member having the same cross-sectional shape, and can be formed by inexpensive extrusion molding. For this reason, cost increase due to an increase in the number of parts can be suppressed to a minimum. Therefore, the cost can be significantly reduced by reducing the number of parts and the number of assembling steps and the cost of manufacturing parts. In addition, although the convex part 66 is the structure which protrudes in the opening part of the recessed part 60, it is not the rib provided over the full width of the recessed part 60, but is comprised by the protrusion provided in the predetermined space | interval, thereby injection molding. Can be easily formed.

Further, as shown in FIG. 22, the gasket holding member 61 has a gasket removal preventing rib 64 at the opening portion of the gasket holding recess 63. With such a configuration, the gasket 62 can be firmly fixed and held on the gasket holding member 61 without dropping off. With such a configuration, reliable sealing performance can be maintained. Further, the rib for preventing gasket removal 64 has a structure that projects into the opening of the gasket holding recess 63. Since the gasket removal preventing rib 64 is provided on the gasket holding member 61, it can be easily formed by extrusion.

When the door 20 is attached to the inner plate 56 via a hinge, there is a problem that it is difficult to keep the top surface of the outer box 96 and the upper surface of the door 20 in parallel, that is, it is difficult to ensure parallelism. However, in the present embodiment, the door 20 is attached to the hinge mounting bracket 76 connected to the outer box 96 via the inner box 7.

With such a configuration, even when the door 20 is pivotally supported by the inner box 7, the parallelism of the door 20 with respect to the outer box 96 can be secured, and the problem that the door 20 tilts with respect to the outer box 96 is solved. can do. Therefore, even if it is a refrigerator like the built-in type where the inclination of the door 20 is conspicuous, the inclination of the door 20 can be reliably prevented. Therefore, with such a configuration, the quality of the refrigerator can be improved and the yield can be increased to reduce the cost.

Further, the operation display unit 23 provided on the upper portion of the door 20 is installed with the first pressing piece 74a and the second pressing piece 74b of the operation unit unit 71 elastically contacting the inner wall portion of the operation unit installation recess 70. ing. With such a configuration, the electrode film of the operation display unit 23 is pressed against the inner surface of the transparent front plate 68. Therefore, the detection accuracy of the electrostatic capacity at the time of the touch operation can be increased, and the operation quality can be improved.

Furthermore, the operation unit installation recess 70 in which the operation unit unit 71 is installed is provided with an inclined surface 73 a on the back side of the operation unit unit 71. With such a configuration, the gasket 62 is mounted using a dead space generated behind the inclined surface 73a. That is, the operation unit 71 and the gasket 62 are installed such that the operation unit 71 and the gasket 62 are overlapped. With such a configuration, the installation space between the operation unit 71 and the gasket 62 can be reduced, and the center plate 21 can be enlarged correspondingly to increase the visibility.

Further, the gasket 62 provided on the inner plate 56 of the door 20 is provided so as to be positioned between the opening portions of the storage chambers 3 and 4 and the operation unit unit 71. With such a configuration, it is possible to prevent the cool air in the storage chambers 3 and 4 from flowing to the installation back surface portion of the operation unit unit 71 and cooling it. With such a configuration, it is possible to prevent failures such as the occurrence of condensation due to excessive cooling of the operation unit 71.

The lead wire 79 from the operation unit 71 to the main body control unit is bent by opening and closing the door 20. Further, the length of the lead wire required when the door 20 is closed is shorter than the length of the lead wire required when the door 20 is opened. In particular, when a hinge having a link mechanism is used, the required difference in the length of the lead wire between the closed state and the opened state becomes large. For these reasons, a load is applied to the lead wire 79 and the lead wire 79 may be disconnected.

However, in the present embodiment, as shown in FIG. 30, the lead wire 79 is drawn into the bottom surface of the refrigerator main body 1 through the through hole 80 provided in the hinge cover 78 of the lower hinge 75b. Further, the refrigerator 90 of the present embodiment is configured such that the lead-in position of the lead wire 79 is regulated by at least one of the through hole 80 and the clip 81. For this reason, the difference between the length of the lead wire required when the door 20 is closed and the length of the lead wire required when the door 20 is opened can be reduced. Even if the lead wire 79 extends and contracts due to the opening and closing of the door 20 and the length dimension thereof changes, the remaining lead wire 79 contracts between the end of the door 20 and the lower hinge 75b. Can be prevented.

That is, even if the door 20 is closed and the lead wire 79 is left in an excess state, the lead wire 79 of the portion having the excess dimension is restricted from moving to the center side of the refrigerator main body 1 through the through hole 80. When the clip 81 is provided through the through hole 80, it moves to the bottom surface side of the refrigerator main body 1 through the through hole 80 and the clip 81. Therefore, even when the door 20 is pivotally supported using a hinge having a link mechanism and the lead wire 79 is greatly expanded and contracted, the load due to the bending of the lead wire 79 and the biting of the lead wire 79 are not caused. It is suppressed and disconnection etc. can be prevented.

In particular, the through-hole 80 restricts the movement of the lead wire 79 from the moving rotation shaft 757 to the side opposite to the central portion side of the refrigerator body 1. With such a configuration, the bending amount and the bending amount of the lead wire 79 are reduced, and the lead wire 79 can be more reliably prevented from being damaged.

The clip 81 is configured to restrict the movement of the lead wire 79 in the depth direction of the refrigerator body 1 from the lower hinge 75b to the back side of the refrigerator body 1, and allows the movement of the lead wire 79 in the axial direction. It is configured to With such a configuration, it is possible to prevent an excess portion of the lead wire 79 generated by opening and closing the door 20 from being bitten by the lower hinge 75b.

In particular, in the present embodiment, the through hole 80 is provided on an extension line X (see FIG. 30) of an imaginary line passing through the center of the door 20 in the thickness direction when the door 20 is fully opened. Yes. With such a configuration, an excessive dimension portion of the lead wire 79 generated when the door 20 is closed slides through the through hole 80 and moves to the refrigerator main body 1 side. Therefore, with such a configuration, bending of the lead wire 79 at the hinge portion can be suppressed, and the lead wire 79 can be more reliably prevented from being damaged.

Furthermore, the central plate 21 of the door 20 has a multiple structure in which a heat insulating gas is enclosed. Further, a heat insulating material 59 is provided on the outer peripheral portion of the central plate 21 between the outer plate 57 and the inner plate 56 of the edge frame 55 that sandwiches and holds the central plate 21. With such a configuration, the heat insulation of the door 20 is improved, and a refrigerator with good cooling performance is obtained.

Note that the refrigerator 90 exemplified in the present embodiment is configured to supply the cold air generated in one cooling chamber 25 to the two storage chambers 3 and 4 for cooling. The refrigerator 90 exemplified in the present embodiment is configured such that the amount of cool air supplied to each of the storage rooms 3 and 4 is controlled by the damper device 36. With such a configuration, the storage chambers 3 and 4 can be cooled to different temperature zones. In addition, the damper device 36 controls the supply of cold air to the storage chambers 3 and 4 independently by the first flap 40 and the second flap 41. With such a configuration, each of the storage chambers 3 and 4 can be accurately cooled to a predetermined temperature.

Further, the cooling fan 27 for supplying cold air to the storage chambers 3 and 4 is composed of a multi-blade fan 27a that blows air in the circumferential direction. With such a configuration, there is no need to provide a forward air passage like a propeller fan that blows forward. Further, the damper device 36 need not be provided in front of the fan. Therefore, the size in the front-rear direction of the cooling chamber 25 provided with the cooler 26 and the cooling fan 27 can be reduced, and the storage capacity can be increased by increasing the front-rear size of the storage chambers 3 and 4 accordingly.

In particular, in the refrigerator 90 of the present embodiment, the first through hole 43 and the second through hole 44 are provided in the cooling chamber side wall surface plate 32 of the wall surface unit 30 that partitions between the storage chambers 3 and 4 and the cooling chamber 25. ing. Further, the damper device 36 of the cooling fan 27 is in communication with each of the first blowing air passage 47 and the second blowing air passage 48. With such a configuration, the size in the front-rear direction can be further reduced. That is, the cool air from the cooling fan 27 is directly supplied to the first blowing air passage 47 and the second blowing air passage 48 through the first through hole 43 and the second through hole 44, respectively. Accordingly, the cooling fan 27, the first blowing air passage 47, and the second blowing air passage 48 are compared with those in which the cooling fan 27 and the first blowing air passage 47 and the second blowing air passage 48 are connected by a duct member or the like. The positional relationship in the front-rear direction and the vertical direction of the air passage 48 can be minimized. Thereby, the storage capacity of the storage chambers 3 and 4 can be further increased.

That is, with the configuration as described above, the air passage configuration can be made compact, and a refrigerator having a large storage capacity relative to the external dimensions of the refrigerator body 1 and capable of high cooling control can be obtained.

Further, the guide case 33 of the cooling fan 27 is provided with only one discharge opening 35. The discharge opening 35 is covered with a damper device 36. Further, the first opening 37 and the second opening 38 of the damper device 36 are formed adjacent to each other. Moreover, the 1st blowing air path 47 and the 2nd blowing air path 48 which are connected to the 1st opening part 37 and the 2nd opening part 38, respectively are also installed adjacently. With such a configuration, the distance between the two can be reduced. With such a configuration, the width dimension of the refrigerator body 1 can be suppressed within a predetermined dimension, and the refrigerator body 1 can be easily applied as an undercounter-type wine warehouse or the like in which the width dimension of the refrigerator body is regulated.

Further, the guide case 33 of the cooling fan 27 and the case 42 of the damper device 36 are integrated. With such a configuration, the number of parts can be reduced. In addition, the guide case 33 of the cooling fan 27 and the case 42 of the damper device 36 are configured as separate bodies, so that it is possible to prevent cold air leakage and the like that are a concern when connected to each other. Therefore, the quality can be improved while simplifying the configuration.

On the other hand, the guide case 33 of the cooling fan 27 is configured such that the side wall covering the outer periphery of the multiblade fan 27a is formed in an Archimedean spiral shape around the rotation axis of the multiblade fan 27a. With such a configuration, it is possible to minimize the air blowing loss of the cool air discharged from the multiblade fan 27a, and efficient cooling becomes possible.

In addition, the rotation axis of the cooling fan 27 is provided so as to be biased toward the opening side of the damper device 36 located on the rotation direction side of the cooling fan 27, in this embodiment, the second opening 38 side. With such a configuration, the cool air from the multi-blade fan 27a that tends to be supplied in the direction opposite to the fan rotation direction can be supplied to the first opening 37 and the second opening 38 substantially evenly. With such a configuration, the storage chambers 3 and 4 can be efficiently cooled.

Also, even if configured as described above, there is a tendency that a cold air bias remains. Therefore, in the present embodiment, the first blowing air passage 47 that communicates with the first opening 37, which tends to be supplied with a lot of cold air, is longer than the second blowing air passage 48 that communicates with the second opening 38. With such a configuration, the air path resistance on the side of the first opening 37 to which a large amount of cool air is supplied increases, and the amount of cool air blown out from the first blowing air path 47 and the second blowing air path 48 is made more uniform. Thus, the storage chambers 3 and 4 can be efficiently cooled.

In addition, since the upper return ports 52b for returning the cold air from the upper storage chamber 3 to the return air passage 50 are distributed on the left and right sides of the first blowing air passage 47, the cold air in the upper storage chamber 3 is on the upper side. It is distributed on both sides of the storage chamber 3. Thereby, the cooling of the upper storage chamber 3 can be made uniform with little bias.

Further, the portion where the first blowing air passage 47 and the second blowing air passage 48 are adjacent, and the portion where each of the first blowing air passage 47 and the second blowing air passage 48 and the return air passage 50 are adjacent, It is composed of multiple walls having a heat insulating layer 54. With such a configuration, heat transfer between the air paths can be suppressed to a minimum, and efficient cooling becomes possible.

As mentioned above, although the refrigerator 90 by an example of embodiment of this indication was demonstrated using the said embodiment, this indication is not limited to this, In the range which achieves the objective of this indication It goes without saying that various changes can be made.

For example, although the refrigerator 90 of the present embodiment is an undercounter type refrigerator that is built in and used in a system kitchen or the like, it may be a refrigerator that is used without being built in. Moreover, although the refrigerator 90 of this Embodiment was shown as a refrigerator suitable for wine preservation | save, the normal refrigerator which preserve | saves food preservation | save may be sufficient.

Further, in the present embodiment, the refrigerator having two storage rooms is illustrated, but the number of storage rooms may be two or more, and the temperature zones of the respective storage rooms may be set to be different from each other. .

As described above, the embodiment disclosed this time should be considered as illustrative in all points and not restrictive. That is, the scope of the present disclosure is shown not by the above description but by the scope of claims, and is intended to include meanings equivalent to the scope of claims and all modifications within the scope.

As described above, the present disclosure provides a refrigerator capable of realizing a significant cost reduction by reducing the number of door parts and assembly man-hours. Therefore, it can be widely applied not only to wine cellars, but also to undercounter refrigerators, storages with doors, etc., regardless of general use or business use.
