JP 2014-43982 A

  In order to display a large amount of information on a display device, a display device such as a liquid crystal display is enlarged. As a result, the amount of heat generated from the display device increases, and heat accumulates inside the door. Heat from the door may be transferred to the storage room and the temperature of the storage room may increase.

  In view of the above, an object of the present invention is to provide a refrigerator that can suppress an increase in temperature inside the door accompanying heat generation of the display device and can eliminate the influence of heat generation of the display device on the storage.

  In the present invention, a display device is provided on a door that opens and closes a storage chamber, and a storage portion that forms a storage space for storing the display device is provided in the door, and heat generated by the display device is discharged to the storage portion. For this purpose, a discharge port is formed.

  The heat generated from the display device accumulates in the storage unit, but is exhausted from the discharge port, thereby preventing the temperature inside the door from rising.

  A discharge port is formed on the side surface of the door, and the top surface of the storage portion is formed to be inclined upward toward the side surface where the discharge port is located. The warmed air flows along the inclination of the top surface, and the air flow in the storage portion becomes smooth, and the air can be efficiently exhausted. Further, it is possible to prevent the hot air from the outlet from directly hitting the user.

  An intake port for taking outside air into the storage space is formed in the storage unit, and the discharge port is located above the intake port. Natural convection from the lower part to the upper part tends to occur in the storage part, and air having a low temperature flows into the storage part, so that the display device can be cooled.

  A heat conduction member for diffusing heat from the storage unit is provided on the side surface of the door, and the heat conduction member is disposed in the vicinity of at least one of the discharge port and the top surface of the storage unit.

  In addition to exhaust heat due to exhaust, exhaust heat due to heat conduction is performed, and exhaust heat is distributed. Although the temperature of the side surface of the door near the discharge port increases due to the exhaust heat, the heat is transferred to the heat conducting member, so that the temperature unevenness of the side surface of the door near the discharge port is eliminated.

  When the door is closed, the display device is driven, and heat generated from the display device is transmitted to the heat conducting member and used for preventing condensation. Heat from the display device is transmitted to the side surface of the door by the heat conducting member, the side surface of the door is warmed, and condensation does not occur on the side surface.

  The storage portion faces the side surface of the door, and a discharge port is formed on this side surface. Thereby, a discharge port can be arrange | positioned in the position which is not conspicuous.

  The bottom surface of the storage portion is formed to be inclined downward toward the side surface where the intake port is located. Air entering from the intake port flows along the slope of the bottom surface, and low temperature air spreads throughout the storage unit.

  The door has a translucent door front plate, a storage portion is provided behind the door front plate, and an opening that leads to the storage space is formed on the side of the door to attach and detach the display device. A cover for closing the cover is provided, and a discharge port is formed in the cover. It is not necessary to form a discharge port directly in the door itself, and the heat insulation of the door is maintained.

  Of the side surfaces in the left-right direction of the door, one side surface is rotatably supported by a hinge, and a discharge port is formed on the other side surface. An intake is formed on one side surface of the door in the left-right direction. Even when the door is open, the outlet is not blocked. And the flow of the air which goes to the other side from the one side of the left-right direction arises in a storage part, and it can discharge | emit smoothly.

  According to the present invention, even if the display device in the door generates heat, the heat can be exhausted from the door, so that the temperature rise inside the door can be suppressed and the storage chamber can be prevented from being affected by heat generation.

(First embodiment)
The refrigerator of this embodiment is shown in FIG. The refrigerator includes a plurality of storage rooms, and doors 1 to 3 that open and close each storage room are provided. The doors 1 and 2 of the refrigerating room which is the largest storage room are of a double door type, and the doors 1 and 2 are provided on the left and right. The outer ends of the doors 1 and 2 are rotatably supported by hinges. The left door 2 opens and closes around the left end, and the right door 1 opens and closes around the right end. Doors 3 of other storage rooms such as a vegetable room and a freezer room are of a drawer type.

  The refrigerator includes a display device 10 for displaying various information. As shown in FIGS. 2-4, the display apparatus 10 is provided in the inside of the door 1 of the right side of a refrigerator compartment, for example. The doors 1 and 2 are constituted by a door front plate 11 having translucency such as glass, an edging member 12 for holding the door front plate 11, and an inner surface plate 13 facing the storage chamber. The edging member 12 sandwiches the periphery of the door front plate 11. The inner surface plate 13 is formed in a predetermined shape so as to have a door pocket or the like. The peripheral edge of the inner surface plate 13 is overlapped on the outer side of the peripheral edge of the edging member 12. Synthetic resin is foamed in the space surrounded by the door front plate 11, the edging member 12, and the inner surface plate 13 to form the heat insulating material 14. Therefore, the edging member 12 becomes the upper, lower, left and right side surfaces of the doors 1 and 2.

  The display device 10 is located behind the door front plate 11. A storage portion 15 for storing the display device 10 is formed in the door 1. The display by the display device 10 can be visually recognized through the door front plate 11.

  The display device 10 includes a display panel such as liquid crystal or organic EL, a drive circuit, and an operation unit, which are integrated into one display unit. The operation unit is a capacitive touch panel. In addition, you may use the liquid crystal with a built-in optical sensor in which the operation part and the display panel were integrated.

  The storage unit 15 includes a storage cover 16. The storage cover 16 made of synthetic resin has a top surface, a bottom surface, and a rear surface, and has a shape that is long in the left-right direction. The front surface and the left and right side surfaces of the storage cover 16 are open. A flange 17 formed on the front side of the storage cover 16 contacts the door front plate 11, and both the left and right sides of the storage cover 16 contact the left and right border members 12. A space surrounded by the storage cover 16, the door front plate 11, and the edging member 12 is a storage space for storing the display device 10. The storage cover 16 prevents the synthetic resin foamed when the door 1 is manufactured from entering the storage space.

  An opening for inserting and removing the display device 10 is formed in the edging member 12 in contact with the storage cover 16. The opening is formed in the rim member 12 on the left side of the door 1, that is, the rim member 12 on the center side facing the other door 2. A cover 18 that closes the opening is detachably provided. The cover 18 functions as a side surface of the storage cover 16 and constitutes a part of the storage unit 15.

  A guide 19 for holding the display device 10 is provided in the storage cover 16. The guides 19 are respectively formed up and down along the left-right direction. The guide 19 slidably guides the display device 10 that is inserted and removed from the opening. The guide 19 sandwiches and holds the upper and lower portions of the display device 10 and positions the display device 10 so that the display device 10 is in close contact with the door front plate 11. Here, the top surface 20 and the bottom surface 21 of the storage portion 15 are formed horizontally, and the top surface 20 is located above the upper guide 19. When the display device 10 is stored in the storage unit 15, a gap is formed between the top surface 20 of the storage unit 15 and the upper part of the display device 10 so that air flows.

  The door 1 has a heat exhaust structure for exhausting heat generated from the display device 10 from the storage space. As shown in FIGS. 2 and 4, an exhaust outlet 22 is formed in the storage portion 15. The discharge port 22 is formed in the upper part of the cover 18. Further, an intake port 23 for intake is formed in the storage unit 15. The intake port 23 is formed on the side surface opposite to the side surface of the door 1 where the cover 18 is located. The intake 23 is formed at a position facing the lower portion of the storage portion 15 of the edging member 12. The discharge port 22 is located above the intake port 23.

  The display device 10 generates heat when driven. The air heated by heat rises and reaches the upper part of the storage space in the storage unit 15. Air accumulated in the upper part of the storage space is discharged from the discharge port 22 to the outside of the door 1. The high-temperature air discharged from the door 1 rises through the space between the left and right doors 1 and 2 and diffuses. In the storage space, an updraft is generated and external air flows from the intake 23 into the storage space. Here, when the discharge port 22 is disposed on the side surface on the center side of the door 1, the discharge port 22 is not opposed to the front wall of the storage chamber when the door 1 is opened. Therefore, a stable exhaust heat structure can be configured.

  In this way, low-temperature air enters the storage space, and high-temperature air is discharged to the outside. Therefore, the heat generated by the display device 10 does not stay inside the door 1 and the temperature inside the door 1 can be prevented from rising. As a result, the storage room is completely unaffected by heat generation.

(Second Embodiment)
In the exhaust heat structure of the refrigerator of the present embodiment, as shown in FIG. 5, the top surface 20 of the storage unit 15 is formed on an inclined surface in order to facilitate exhaust heat. The top surface 20 is formed so as to be inclined upward toward the side surface of the door having the discharge port 22. Note that the inlet 23 is not provided. Other configurations are the same as those of the first embodiment.

  When the display device 10 operates to generate heat, the warmed air rises. The raised air flows along the top surface 20 of the storage portion 15 toward the discharge port 22 and is discharged from the discharge port 22 to the outside of the door 1. Thus, by making the top surface 20 into an inclined surface, the air that has reached the top surface 20 is swept away by the air that has risen later, and the air pressure in the upper part of the storage space is increased, and the air is discharged from the discharge port 22. It is possible to exhaust efficiently. Therefore, heat does not stay in the storage space, heat conduction from the door 1 to the storage room can be reduced, and temperature rise of the storage room can be prevented. In this manner, by making the top surface 20 of the storage unit 15 an inclined surface, heat can be exhausted even if only the discharge port 22 is provided.

  As shown in FIG. 6, an intake port 23 may be provided on the side surface opposite to the discharge port 22. Thereby, air with a low temperature flows into the storage space, and natural convection is promoted. The display device 10 can also be cooled by the low-temperature air, and the temperature rise inside the door 1 can be suppressed.

(Third embodiment)
In the exhaust heat structure of the refrigerator of the present embodiment, as shown in FIG. 7, the bottom surface 21 of the storage portion 15 is formed on an inclined surface in order to facilitate exhaust heat. The bottom surface 21 is inclined downward toward the side surface of the door 1 where the intake port 23 is located. Other configurations are the same as those of the second embodiment.

  The air heated by the heat generated by the display device 10 flows along the top surface 20 and is discharged from the discharge port 22. Along with this, external air is introduced from the intake port 23. Since the bottom surface 21 of the storage unit 15 is an inclined surface, the air introduced from the intake port 23 flows along the bottom surface 21 toward the side surface on the discharge port 22 side, and the low-temperature air enters the entire storage space. It becomes easy to spread. Moreover, since the volume of the storage space is larger than the storage spaces of the first embodiment and the second embodiment, the display device 10 can easily dissipate heat, and the temperature rise of the display device 10 that is a heat generation source can be suppressed. Therefore, natural convection from the lower part of the storage space toward the upper part is further promoted, and the temperature rise inside the door 1 can be suppressed.

  Further, as shown in FIG. 8, it may be provided on the same side as the discharge port 22 and the intake port 23. The top surface 20 is formed with an upward slope toward the discharge port 22, and the bottom surface 21 is formed with a downward slope toward the intake port 23. When the air heated by the heat generated by the display device 10 flows along the top surface 20 toward the discharge port 22, the air is diluted on the side surface opposite to the side surface where the discharge port 22 is located. It becomes easy for air that has entered to flow toward the opposite side. As a result, convection flows from the intake port 23 toward the opposite side surface through the lower portion of the storage space, and further toward the discharge port 22 through the upper portion of the storage space, and exhaust heat in the storage space is promoted.

(Fourth embodiment)
As shown in FIG. 9, packings 25 are provided on the side surfaces of the left and right doors 1 and 2 facing each other in the refrigerator along the vertical direction. When the doors 1 and 2 are closed, the packings 25 are attracted to each other. Thus, the space between the doors 1 and 2 is hermetically sealed. The inner side surface of the packing 25 faces the storage chamber, and the outer side surface is exposed to the outside. The inner side touches the cold. Here, in the door 1 provided with the display apparatus 10, the thickness of the heat insulating material 14 is thin in the part with the accommodating part 15. FIG. Therefore, the temperature of the storage room is easily transmitted to the side surface of the door 1, and condensation occurs on the side surface.

  In order to prevent such condensation, a heater 26 is provided on the inner surface side of the edging member 12 that forms the side surfaces of the doors 1 and 2 as described in a patent document (Japanese Patent Laid-Open No. 2007-107760). The heat of the heater 26 prevents condensation on the side surfaces of the doors 1 and 2.

  However, in order to prevent condensation, a heat source such as the heater 26 must be provided separately. Therefore, in the refrigerator of this embodiment, condensation is prevented by using heat generated from the display device 10. That is, as shown in FIG. 10, a heat conducting member 27 for diffusing exhaust heat from the storage portion 15 is provided on the side surface of the door 1. Other configurations are the same as those in the first to third embodiments.

  The heat conducting member 27 has a good heat conductivity such as an aluminum tape and is a thin strip. The heat conducting member 27 is attached to the outer surface of the storage cover 16. The outer surface of the storage cover 16 is a surface facing the heat insulating material 14. The heat conducting member 27 is disposed on the upper portion of the storage cover 16 and passes near the discharge port 22. Further, the heat conducting member 27 is provided on the side surface of the door 1 on the center side. That is, the heat conducting member 27 is attached to the back surface of the edging member 12 along the vertical direction. The surface of the edging member 12 on which the heat conducting member 27 is disposed is an outer portion from the packing 25.

  Due to the heat generated by the display device 10, the upper portion of the storage cover 16 is warmed, and heat is transferred from the storage cover 16 to the heat conducting member 27. This heat is transmitted to the side surface of the door 1 through the heat conducting member 27. That is, the heat generated by the display device 10 is conducted to the side surface of the door 1 and radiated over a wide area. Thereby, exhaust heat is accelerated | stimulated and heat does not retain in the door 1 inside. Moreover, the side surface of the door 1 is warmed by the heat from the heat conducting member 27, and no condensation occurs on the side surface. Moreover, the temperature of the side surface of the door 1 near the discharge port 22 increases due to exhaust heat, but this heat is transmitted to the heat conducting member 27 to eliminate the deviation of the temperature distribution on the side surface of the door 1 near the discharge port 22. be able to. Therefore, a portion having a low temperature is not formed on the side surface of the door 1, and it is possible to prevent local condensation.

  By the way, the condensation of the door 1 tends to occur immediately after the door 1 is opened and closed. When the display device 10 is not driven, it is impossible to prevent condensation using the heat of the display device 10. Therefore, when the door 1 is closed, the display device 10 is driven. The refrigerator includes a detector such as a microswitch that detects opening and closing of the door 1. When it is detected that the door 1 is closed, the display device 10 is driven for a predetermined time or until the heat conducting member 27 reaches a predetermined temperature. The temperature of the heat conducting member 27 is detected by a temperature sensor.

  In this way, when the door 1 is closed, the side surface of the door 1 is warmed by the heat of the display device 10, so that condensation on the side surface of the door 1 can be prevented. At this time, the display device 10 is driven, but since the user is still near the refrigerator, the user does not feel uncomfortable even if something is displayed. Therefore, it is preferable to intentionally provide useful information for the user. For example, the display device 10 displays an electricity bill, stored information, a message between family members, and the like. This eliminates unnecessary display and prevents condensation.

  As described above, in the refrigerator of the present invention, the display device 10 is provided on the door that opens and closes the storage chamber, and the storage unit 15 that forms the storage space for storing the display device 10 is provided in the door.

  A discharge port 22 is formed on the side surface of the door 1, and the top surface 20 of the storage unit 15 is formed to be inclined upward toward the side surface where the discharge port 22 is located. Thereby, the flow of the air in the storage part 15 becomes smooth, and it becomes easy to exhaust. Moreover, the discharge port 22 can be made inconspicuous.

  An intake port 23 for taking outside air into the storage space is formed in the storage unit 15, and the discharge port 22 is positioned above the intake port 23. Natural convection is likely to occur in the storage portion 15, and heat can be discharged efficiently.

  The bottom surface of the storage portion 15 is formed to be inclined downward toward the side surface where the intake port 23 is located. Thereby, the low-temperature air that has entered from the intake port 23 can be distributed throughout the storage unit 15.

  Of the side surfaces of the door 1 in the left-right direction, one side surface is rotatably supported by a hinge, and a discharge port 22 is formed on the other side surface. An intake port 23 is formed on one side surface of the door 1 in the left-right direction. Thereby, the flow of the air which goes to the other side from the one side of the left-right direction can be produced in the accommodating part 15, and it can discharge | emit smoothly.

  A heat conducting member 27 for diffusing exhaust heat from the storage unit 15 is provided on the side surface of the door 1. Thereby, the heat accumulated in the storage portion 15 can be radiated through the heat conducting member 27. The heat conducting member 27 is disposed in the vicinity of at least one of the discharge port 22 and the top surface 20 of the storage unit 15. Thereby, the heat generated by the display device 10 is efficiently guided to the discharge port 22. The temperature unevenness of the side surface of the door in the vicinity of the discharge port 22 is eliminated, and local condensation can be prevented.

  When the door 1 is closed, the display device 10 is driven, and the heat generated from the display device 10 is transmitted to the heat conducting member 27 and used for preventing condensation. Thereby, the heat from the display device 10 is transmitted to the side surface of the door 1, and condensation can be prevented from occurring on the side surface of the door 1.

  A display device 10 is provided on the door 1 that opens and closes the storage chamber. The door 1 has a light-transmitting door front plate 11, and a storage space for storing the display device 10 is formed behind the door front plate 11. The storage unit 15 is provided with a discharge port 22 for discharging heat generated by the display device 10 and an intake port 23 for taking outside air into the storage space.
