BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be noted that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are essential to the solution of the invention.
(embodiment)
FIG. 1 is an external view of a refrigerator 100. FIG. Refrigerator 100 includes a plurality of storage compartments, specifically refrigerator compartment 101 , ice making compartment 102 , upper freezer compartment 103 , lower freezer compartment 104 , and vegetable compartment 105 . A partial/chilled switching chamber is provided inside the refrigerating chamber 101 .

FIG. 2 is a diagram for explaining the refrigerator compartment 101 in detail. Refrigerating compartment 101 is closed by a double-opening door composed of a first door 201 and a second door 202 . FIG. 2 shows a state in which the second door 202 is opened.

FIG. 3 is a diagram for explaining the first door 201 in detail, and is a perspective view when the first door 201 is viewed from the inside of the refrigerator. The first door 201 is provided with an upper gasket 301 and a lower gasket 302 for sealing the gap between the first door 201 and the refrigerator main body when the first door 201 is closed. A first gasket 303 is provided at a portion facing the second door 202 when the first door 201 is closed. Although not shown in FIG. 3, the second door 202 is also provided with a second gasket 401 at a portion facing the first door 201 when the second door 202 is closed. When the first door 201 and the second door 202 are closed, the first gasket 303 and the second gasket 401 can suppress cold air from leaking through the gap between the two doors.

FIG. 4 is a sectional view of refrigerating compartment 101 viewed from above with first door 201 and second door 202 closed. A first gasket 303 is attached to a first outer peripheral member 402 that forms the outer periphery of the first door 201 . Also, the second gasket 401 is attached to a second outer peripheral member 403 that forms the outer periphery of the second door 202 . Also, the first gasket 303 has a magnet 404 and the second gasket 401 has a magnet 405 . When the first door 201 and the second door 202 are closed, the magnets 404 and 405 are attracted to each other to seal the gap between the two doors.

Since the first gasket 303 and the second gasket 401 are cooled by the cold air inside the refrigerator, condensation occurs on the surface of the first gasket 303 outside the refrigerator and on the surface of the second gasket 401 outside the refrigerator. Likely to happen. A heater 406 is provided inside the first door 201 and near the first gasket 303 in order to prevent the occurrence of this dew condensation. The heater 406 first heats the outside surface of the first gasket 303 , and then heats the outside surface of the second gasket 401 via the first gasket 303 . As a result, it is possible to prevent condensation from occurring on the outside surface of the first gasket 303 and the outside surface of the second gasket 401 .

Refrigerator 100 of the present embodiment is characterized in that first peripheral member 402 is a resin member mixed with filler having high thermal conductivity. The heat of the heater 406 can be easily conducted to the first gasket 303 by forming the first outer peripheral member 402 from a resin member mixed with a filler having high thermal conductivity. Therefore, the heating time of the heater 406 is shortened compared to the case where a resin member mixed with a substance having high thermal conductivity such as a filler is not used. It is possible to reduce power consumption when heating the sealing member. It should be noted that the entire outer periphery of the first door 201 may be formed of a resin member mixed with a filler, or the resin material may face the second door 202 when the first door 201 and the second door 202 are closed. Only the portion may be formed of a resin member mixed with a filler. Among the outer peripheral members forming the outer periphery of the first door 201, at least the portion facing the second door 202 when the first door 201 and the second door 202 are closed is a resin member mixed with a filler. should be formed with

Furthermore, the refrigerator 100 of the present embodiment is characterized in that the second outer peripheral member 403 as well as the first outer peripheral member 402 are made of a resin member mixed with a filler having high thermal conductivity. Since the heat of the outside air is transferred to the second gasket 401 via the second peripheral member 403 by using a resin member mixed with a filler having high thermal conductivity as the second peripheral member 403, the heater Heating of the outside surface of the second gasket 401 away from 406 can be facilitated. Therefore,
The heating time of the heater 406 is shorter than when a resin member mixed with a substance with high thermal conductivity such as a filler is not used as the outer peripheral member of the second door 202. As a result, the first gasket 303 and the second gasket 401, the power consumption can be reduced. In addition, the entire outer circumference of the second door 202 may be formed of a resin member mixed with a filler, or the first door 201 and the second door 202 may be closed to face the first door 201. Only the portion may be formed of a resin member mixed with a filler. Of the outer peripheral member forming the outer periphery of the second door 202, at least the portion facing the first door 201 when the first door 201 and the second door 202 are closed is a resin member mixed with a filler. should be formed with Further, by bringing a portion of the first gasket 303 into contact with the first outer peripheral member 402, it becomes easier to transfer the heat of the outside air to the surface of the first gasket 303 on the outer side of the chamber. Further, by bringing a part of the second gasket 401 into contact with the second peripheral member 403, it becomes easier to transfer the heat of the outside air to the surface of the second gasket 401 on the outer side of the chamber.

In addition, if a filler with high thermal conductivity is mixed, the fluidity when molding the resin member will decrease, but by using polyamide resin (for example, 6-nylon) as the main material of the resin member, the fluidity will be increased. be able to.

Also, by setting the thermal conductivity of the resin member mixed with a filler having high thermal conductivity to 1 W/mk to 50 W/mk, the balance between heat transport and heat absorption can be optimized.

In addition, the first gasket 303 and the second gasket 401 are divided into parts outside the refrigerator and parts inside the refrigerator, and the parts outside the refrigerator have a higher thermal conductivity than the parts inside the refrigerator. By doing so, it is possible to suppress heat penetration into the chamber. In addition, the first outer peripheral member 402 is divided into an outer part and an inner part at the position where the first gasket 303 is attached, and the outer part has a higher thermal conductivity than the inner part. By using high parts, it is possible to suppress heat infiltration into the chamber. In addition, the second outer peripheral member 403 is divided into an outer part and an inner part at the position where the second gasket 401 is attached, and the outer part has a higher thermal conductivity than the inner part. By using high parts, it is possible to suppress heat infiltration into the chamber.
