- the rear frame may be formed of a thermoplastic resin having high heat transfer characteristics, and preferably, may be formed of ABS.
- the side frame and the heat bridge is formed of a metal material, preferably may be formed of an aluminum material.
- the heat bridge is preferably in close contact with the inner surface of the expansion portion of the windshield.
- FIG. 5 is a perspective view showing another embodiment of a refrigerator according to the present invention.
- FIG. 7 is a partially cutaway perspective view of the subdoor of FIG. 6.
- the panel assembly 10 and the frame assembly 20 may be referred to as reducing condensation generation at the connection portion 10a connected to each other.
- the refrigerator may reduce condensation not only on the connection portion 10a but also on the entire panel assembly 10. It can also reduce energy consumption very effectively. It is possible to provide a refrigerator having improved insulation and improved usability.
- a refrigerator may be provided that can see the inside of the refrigerator very transparently through the panel assembly 10 even under adverse conditions (a condition where condensation is very easy).
- Such a refrigerator may be a home refrigerator. Therefore, the transparent window is prevented from becoming cloudy due to dew generation, and the inside of the refrigerator may be more clearly seen.
- argon gas is an inert gas that has better thermal insulation performance than air and is capable of preventing chemical alteration, it is preferable to use argon gas rather than air.
- the mutual relationship between the panel assembly 10, the rear frame 200, the upper frame 500, and the lower frame 600 may be similar to each other.
- the basic structure of the rear frame 200 and the side frame (300,400) will be described here, and the detailed structure of the rear frame (200) and the side frame (300,400) will be described later. It demonstrates in an Example.
- the first end 220 of the rear frame 200 is preferably connected to the rear panel 12 to support the rear panel 12.

- the side frames 300 and 400 are located rearward from the rim of the extension 16a of the front panel 16, so that when the user sees the door from the front of the door, these side frames 300 and 400 are located. May not be visible. Therefore, the front panel 16 of the panel assembly 10 is preferably equal to the size of the door. Of course, a planar shape or a curved shape may be formed.
- the panel connection part 310 may be connected to the rear surface of the extension part 16a of the front panel 16. Thus, the panel connection part 310 is not visible.
- the heating unit 30 may be installed in the vicinity of the connecting portion 10a between the panel assembly 10 and the frame assembly 20.
- an opaque part 50 is provided on an inner surface of the expansion part 16a of the front panel 16 so that the heat generating part 30 is not visible from the outside of the door, and the heat generating part 30 is provided on the inner surface of the opaque part 50. Is preferably located.
- the opaque part 50 may be easily implemented by opaquely printing the inner surface of the front panel 16.
- heat generated from the heat generating unit 30 may be effectively transferred to the peripheral portion of the front panel 16 through an attachment configuration having thermal conductivity.
- the panel assembly 10 is a see-through panel (see-through)
- the heat insulator can also be prevented from directly contacting the heat generating portion (30).
- the side frames 300 and 400 have a function of compensating for the mechanical strength of the door and preferably serve to prevent dew condensation. That is, the side frames (300, 400) may be a part in contact with the air outside the refrigerator, and thus absorbs heat at room temperature outside the refrigerator, and heat-exchanges with cold delivered to the front of the door (7) to form dew. It is desirable to prevent it.
- the transmission of cold air inside the refrigerator to the outside of the refrigerator is primarily blocked by the rear frame 200. Additionally, when the panel assembly 10 is transparent, cold air is blocked by the insulation 60.
- the rear frame 200 is formed of a thermoplastic resin having excellent heat insulating performance, the cold air may be more effectively blocked from being transferred to the outside of the refrigerator.
- the second end portion 230 of the rear frame 200 that is, a part of the rear frame 200 connected to the side frame 300 is provided inside the side frames 300 and 400, the heat insulating material 60. The cold air can be further prevented from passing through.
- the side frames 300 and 400 are made of a metal material having good heat transfer performance. Accordingly, the side frames 300 and 400 may absorb heat (room temperature) of the outside air of the refrigerator and transmit the inside of the side frames 300 and 400. Accordingly, the heat transferred inward from the side frames 300 and 400 is not blocked by the rear frame 200 and the heat insulating material 60, and heats cold air transferred to the front surface of the subdoor 7 to prevent dew formation. can do.
- the present invention can be applied to the door (7b) that is provided with a separate structure of the windshield of the panel assembly 10.
- the door 7b includes the panel assembly 10a and the frame assembly 20a, and the heating unit 30 is provided adjacent to the connection portion between the panel assembly 10a and the frame assembly 20a.
- the frame assembly 20a includes a first frame 200a and a second frame 300a.
- the panel assembly 10a comprises a plurality of glasses 12a, 14a, 16a.
