Description

refrigerator

The present disclosure relates to a refrigerator suitable for storing wine and the like, in particular, a refrigerator such as a wine storage suitable for being used in a built-in system kitchen or the like.

Generally, refrigerators used for storing and storing wine bottles and cans, for example wine cellars, are often built in a system kitchen or the like.

The wine stored in such a wine cellar is preferably stored at about 14 ° C. to 18 ° C., depending on the type of wine such as white wine and red wine, and the drinking temperature is 7 ° C. It is about ~ 9 ° C.

For this reason, some wine cellars that store wine bottles have a plurality of storage rooms with different storage temperature zones. This type of wine cellar is configured to supply cold air cooled in the cooling chamber in the cooling chamber at the back of the main body to each storage chamber with a cooling fan, and cool and store each storage chamber at a predetermined temperature (for example, , See Patent Document 1).

FIG. 16 shows a conventional wine cellar described in Patent Document 1. A conventional wine cellar 100 shown in FIG. 16 is an electronic cooling type wine cellar, and includes a plurality of

storage chambers

102 and 103 in a main body 101. In such a conventional wine cellar 100, cold air is generated by a cooler in the cooling chamber 104 provided on the back surface of the

storage chambers

102 and 103, and the generated cold air is supplied to the respective storage chambers by the cooling fan 106. The

storage chambers

102 and 103 are respectively cooled.

Since the conventional wine cellar 100 has a plurality of

storage chambers

102 and 103 having different storage temperature zones, there is an advantage that it is easy to use. However, since a plurality of coolers and cooling fans 106 are required for each of the

storage chambers

102 and 103, the cost becomes expensive. In addition, since a propeller fan that blows air forward is used for the cooling fan 106, an air path portion directed forward from the discharge port of the cooling fan 106 is required. For this reason, the wine chamber has a large size in the front-rear direction of the cooling chamber 104 portion. On the other hand, undercounter type wine cellars that are built into the system kitchen and whose depth dimensions are regulated require

storage chambers

102 and 103 with small depth dimensions, so that the storage capacity is small for the main body outer dimensions. There is a problem that it ends up.

In order to solve such a problem, the cooling fan is used as one unit and the cooling air from the cooling unit is branched and supplied to each storage chamber, and the cooling fan is capable of blowing air in the circumferential direction and has dimensions in the front-rear direction. It is conceivable to use a multi-blade fan that can reduce the size (see, for example, Patent Document 2).

FIG. 17A and FIG. 17B show a cold air supply configuration of a conventional refrigerator described in Patent Document 2. FIG. The conventional refrigerator 200 described in Patent Document 2 is not like a wine cabinet, but has only one cooler. The cooling fan 206 is configured by using a multi-blade fan that can blow in the circumferential direction and can reduce the size in the front-rear direction compared to a propeller fan that blows in the forward direction. Further,

discharge ports

207 and 208 are provided on the left and right sides of the side wall of the fan casing of the multiblade fan.

Ducts

209 and 210 to the storage chambers are connected to the

discharge ports

207 and 208, respectively.

If a cold air supply configuration as described in Patent Document 2 is used, each of the plurality of storage rooms can be cooled by a single cooler, and can be provided at low cost. Further, since the multiblade fan is used, the size in the front-rear direction of the cooling chamber portion can be reduced, and the storage capacity of the storage chamber can be increased accordingly.

However, in the conventional cold air supply configuration as described in Patent Document 2, it is necessary to provide a plurality of

discharge ports

207 and 208 of the cooling fan 206, and the cold air from the cooling fan 206 is converted into a curved shape of the cooling fan 206. The structure which supplies along the side wall of this is needed. For this reason, the space | interval of the

ducts

209 and 210 connected to each of the plurality of storage chambers becomes wide. Therefore, although the conventional cold air supply structure as described in Patent Document 2 can be applied to a unit used as a refrigerator alone, it is an undercounter type wine store that is incorporated and used in the lower part of the system kitchen. Cannot be applied as is. That is, the undercounter type wine cabinet is restricted in the width direction in relation to other devices incorporated in the lower part of the system kitchen, so that the conventional cold air supply configuration as described in Patent Document 2 is used. The refrigerator as it is cannot be applied because the width is too wide. Further, in the conventional cold air supply configuration, the amount of the cold air supplied to each of the plurality of storage chambers is not controlled, so that it is difficult to appropriately cool each storage chamber.

Japanese Patent Laid-Open No. 11-159910 JP 2007-309633 A

This disclosure has been made in view of the above-described problems, and provides a refrigerator capable of increasing the storage capacity while allowing the body width dimension to be controlled within a predetermined dimension.

Specifically, a refrigerator according to an example of the present disclosure includes a refrigerator main body, a plurality of storage rooms provided in the refrigerator main body, a cooling chamber provided on the back side of the refrigerator main body, and a cooler provided in the cooling chamber. And a cooling fan that supplies the cool air generated by the cooler to the plurality of storage chambers. The cooling fan is composed of a multiblade fan that blows air in the circumferential direction. The guide case of the cooling fan has a discharge opening for supplying cold air to the plurality of storage chambers. The discharge opening is preferably provided at a predetermined position of the guide case of the cooling fan.

With such a configuration, the interval between the ducts connected to the cooling fan can be narrowed, and the width of the refrigerator main body can be suppressed within a predetermined dimension. In addition, the size in the front-rear direction of the cooling chamber in which the cooler and the cooling fan are provided can be reduced, and the front-rear size of the storage chamber can be increased. Therefore, with such a configuration, the storage capacity of the storage room can be increased without increasing the size of the refrigerator body.

Further, the refrigerator according to an example of the present disclosure may further include a damper device that covers the discharge opening. In this case, the damper device includes a first opening, a first flap that opens and closes the first opening, a second opening that is adjacent to the first opening, and a second flap that opens and closes the second opening. You may have.

With such a configuration, the amount of cool air supplied to each of the plurality of storage rooms can be controlled, and each storage room can be accurately cooled to a predetermined temperature. Therefore, it is possible to obtain a refrigerator capable of high cooling control, having a large capacity and less subject to installation restrictions.

Further, in the refrigerator according to an example of the present disclosure, the guide case of the cooling fan and the case of the damper device may be integrated.

With such a configuration, the number of parts can be reduced, and the cool air can be prevented from leaking from the connecting portion between the guide case of the cooling fan and the case of the damper device, and the simplification of the configuration and the quality improvement can be realized at the same time Can do.

Further, in the refrigerator according to an example of the present disclosure, the guide case may have a side wall that covers the outer periphery in the rotation direction of the multiblade fan. In this case, the side wall may be formed in an Archimedes spiral shape (centering on the rotation axis of the multiblade fan and having a diameter increasing in accordance with the rotation direction of the rotation shaft) centering on the rotation axis of the multiblade fan. .

Such a configuration can minimize the air loss of the cool air discharged from the multiblade fan, and enables efficient cooling.

Further, in the refrigerator according to an example of the present disclosure, the rotation shaft of the multi-blade fan of the cooling fan is biased toward the opening located on the rotation direction side of the cooling fan among the first opening and the second opening. It may be provided.

With such a configuration, the cool air from the multi-blade fan that tends to be supplied in the direction opposite to the fan rotation direction can be supplied substantially uniformly to the first opening and the second opening. Each storage room can be efficiently cooled.

In addition, a refrigerator according to an example of the present disclosure communicates with a first opening and has a first air outlet having a first air outlet, and a second air that has a second air outlet and communicates with the second opening. A road may be further provided. In this case, in the refrigerator according to an example of the present disclosure, of the first blowout air passage and the second blowout air passage, the blowout air passage on the side where a large amount of cool air from the cooling fan is supplied is longer than the other blowout air passage. It may be configured as follows.

With such a configuration, since the air passage communicating with the opening of the damper device on the side to which a large amount of cold air is supplied is long and has high resistance, the amount of cold air blown out from the first blow air passage and the second blow air passage is reduced. The plurality of storage chambers can be cooled efficiently.

Moreover, the refrigerator according to an example of the present disclosure may further include a wall surface unit that partitions between the plurality of storage rooms and the cooling room. In this case, the wall surface unit may have a cooling chamber side wall surface plate and a storage chamber side wall surface plate. The wall surface unit includes a blowout air passage to a plurality of storage chambers provided between the cooling chamber side wall surface plate and the storage chamber side wall surface plate, and a cooling fan and a damper provided on the cooling chamber side surface of the cooling chamber side wall surface plate. It may be configured so as to have a device and a through hole provided in the cooling chamber side wall face plate for communicating the damper device and the blowout air passage.

With such a configuration, the cool air from the cooling fan is supplied directly to the blowout air passage through the through hole provided between the damper device on the cooling chamber side wall face plate and the air passage. For this reason, the positional relationship in the front-rear direction and the up-down direction between the cooling fan and the blowout air path can be minimized as compared with the case where the cooling fan and the blowout air path are connected by a duct member or the like. . Therefore, with such a configuration, the storage capacity of the storage room can be increased.

Moreover, in the refrigerator according to an example of the present disclosure, the wall surface unit may further include a return air path for cool air from the plurality of storage rooms between the cooling chamber side wall face plate and the storage room side wall face plate. In this case, the return air passage is divided into right and left by the cold air blowing air passage to the storage chamber located below among the plurality of storage chambers. You may have the return port of the cold of several storage chambers in each of the right-and-left end part of the return air path divided | segmented into right and left.

With such a configuration, the cold air flowing from the storage room to the return air passage through the return port is distributed to both sides of the storage room, so that the cold air flows substantially evenly in the storage room. Therefore, with such a configuration, uneven cooling is suppressed, and each of the plurality of storage chambers can be cooled substantially uniformly.

Moreover, in the refrigerator according to an example of the present disclosure, the wall surface unit may include a first blowing air passage and a second blowing air passage that supply cold air to each of the plurality of storage rooms. In this case, at least one of the portion where the first blowing air passage and the second blowing air passage are adjacent to each other and the portion where the return air passage and the first blowing air passage are adjacent to each other has a heat insulating layer. You may be comprised with the wall.

With such a configuration, even if the first blowing air passage and the second blowing air passage, the first blowing air passage and the return air passage, or the second blowing air passage and the return air passage are adjacent to each other. In addition, heat transfer between the two air paths can be suppressed to a minimum, and efficient cooling becomes possible.

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 (see FIG. 9).

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 cold air after cooling the upper storage chamber 3 is sucked into the return air passage 50 from the upper return port 52b. The cold air after cooling the lower storage chamber 4 is sucked into the return air passage 50 from the lower return port 52a. That is, the cool air after cooling the upper storage chamber 3 and the cool air after cooling the lower storage chamber 4 are sucked into the return air passage 50 and merged, and are recovered from the cool air return port 52 to the cooling chamber 25. The

The amount of cool air supplied to each

storage room

3, 4 is individually controlled by the damper device 36 to cool each

storage room

3, 4 to a predetermined temperature.

Further, the cooling temperature of each of the

storage chambers

3 and 4 can be set by touching the operation display unit 23 provided at the upper front portion of the door 20. In addition, the cooling temperature of each of the

storage chambers

3 and 4 can be known from the temperature displayed on the operation display unit 23.

Since the wine bottles stored in the

storage chambers

3 and 4 can be visually observed through the central plate 21 of the door 20, the user can quickly remove the wine bottle without opening the door 20 and searching for a desired wine bottle. be able to.

The refrigerator 80 of the present embodiment is configured such that the cold air generated in one cooling chamber 25 is supplied to the two

storage chambers

3 and 4, and each of the

storage chambers

3 and 4 is cooled. Moreover, the refrigerator 80 of this Embodiment is comprised so that the cold air supplied to each

store room

3 and 4 may be controlled by the damper apparatus 36. FIG. With such a configuration, the

storage chambers

3 and 4 can be cooled to different temperature zones. Moreover, the damper device 36 is configured to independently control the cold air to the

storage chambers

3 and 4 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, in the refrigerator 80 of the present embodiment, the cooling fan 27 that supplies cold air to the

storage chambers

3 and 4 is configured by a multiblade 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 80 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. Thus, the damper device 36 of the cooling fan 27 is in communication with the first blowing air passage 47 and the second blowing air passage 48. With such a configuration, the size of the cooling chamber 25 in the front-rear direction can be further reduced. That is, the cool air from the cooling fan 27 is supplied directly to the first blowout air passage 47 and the second blowout 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 47 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 up-down direction with the air passage 48 can be set to the minimum dimension. Thereby, the storage capacity of the

storage chambers

3 and 4 can be further increased.

With the configuration as described above, it is possible to reduce the size of the air path configuration of the cold air, and it is possible to obtain a refrigerator having a large storage capacity and high cooling control relative to the external dimensions of the refrigerator body 1.

Further, in the refrigerator 80 of the present embodiment, the guide case 33 of the cooling fan 27 is provided with one discharge opening 35. The discharge opening 35 is covered with a damper device 36, and the first opening 37 and the second opening 38 of the damper device 36 are formed adjacent to the discharge opening 35. With such a configuration, the first blowing air passage 47 and the second blowing air passage 48 connected to the first opening 37 and the second opening 38, respectively, are also installed adjacent to each other. The space | interval between the blowing wind paths 48 can be narrowed. Therefore, with such a configuration, the width dimension of the refrigerator body 1 can be suppressed within a predetermined dimension, and can be easily applied to an undercounter type wine cabinet or the like in which the width dimension of the refrigerator body 1 is regulated. it can.

In the refrigerator 80 of the present embodiment, 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, it is possible to prevent the leakage of cold air, which is a concern when the guide case 33 of the cooling fan 27 and the case 42 of the damper device 36 are separated and connected to each other. Therefore, with such a configuration, the quality can be improved while simplifying the configuration.

On the other hand, in the guide case 33 of the cooling fan 27, the side wall covering the outer periphery of the multi-blade fan 27a is formed in an Archimedean spiral shape with the rotation axis of the multi-blade fan 27a as the center. 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.

Moreover, the rotation axis of the cooling fan 27 is provided so as to be biased toward the opening located on the rotation direction side of the cooling fan 27 of the damper device 36, in this embodiment, the second opening 38 side. With such a configuration, the cold air from the multi-blade fan 27a, which tends to be supplied in the direction opposite to the fan rotation direction, can be supplied substantially equally to the first opening 37 and the second opening 38, respectively. it can. Therefore, with such a configuration, each of the

storage chambers

3 and 4 can be efficiently cooled.

In addition, when the bias of the cold air remains in the wall surface unit 30, the length of the first blow-out air passage 47 communicating with the first opening portion 37 where a lot of cold air tends to be supplied is exemplified as illustrated in the present embodiment. Is set to be longer than the second blowing air passage 48 communicating with the second opening 38. With such a configuration, the air path resistance on the first opening 37 side 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. Each of the

storage chambers

3 and 4 can be efficiently cooled.

In addition, in the refrigerator 80 of the present embodiment, the upper return ports 52 b for returning the cold air from the upper storage chamber 3 to the return air passage 50 are provided to be distributed to the left and right of the first blowout air passage 47. With such a configuration, the cool air in the upper storage chamber 3 is distributed to the left and right side portions of the upper storage chamber 3. Therefore, with such a configuration, the cooling of the upper storage chamber 3 can be made uniform with little bias.

Further, in the refrigerator 80 of the present embodiment, the portion where the first blowing air passage 47 and the second blowing air passage 48 are adjacent, the portion where the first blowing air passage 47 and the return air passage 50 are adjacent, and the second A portion where the blowout air passage 48 and the return air passage 50 are adjacent to each other is constituted by a multiple wall 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.
