Embodiment approach 1

[0028] figure 1 It is a front view of a refrigerator according to an embodiment of the present invention relates. figure 2 Mean figure 1 An upper rear perspective view of a region R1 right door opened. image 3 Mean figure 1 Sectional view A-A cross section. based on Figure 1 ~ 3 , Of the schematic structure of the refrigerator 100 will be described. Indicates the width direction of the arrow X direction of the refrigerator 100, the arrow Y direction indicates the depth direction of the refrigerator 100, the direction of arrow Z indicates the height direction of the refrigerator 100.

[0029] Refrigerator includes a refrigerator main body 100 of the box-shaped front surface of the opening 10, the door opening and a plurality of plugging portions 10 of the refrigerator main body 10a. The refrigerator main body 10 to form the outline of the refrigerator 100 by the outer box and the inner box (not shown) as a cabinet, the space between the outer box and the inner box is filled with f...

Embodiment approach 2

[0090] Figure 15 It is a schematic diagram showing an insulating layer structure of a heater unit according to Embodiment 2 of the present invention. In the second embodiment, the insulating configuration of the heater unit 140 is different from the case of the first embodiment. To maintain the insulation resistance, it is necessary to ensure the degree of freedom of the heater configuration, and change the insulation pattern. Unlike the case of the first embodiment. Further, in the present embodiment, in particular, the same reference numerals are described, and the same reference numerals are described using the same reference numerals in the same manner as in the first embodiment.

[0091] For the heater 141, three resistance lines 172 are wound around the core wire 171 and coated by the base insulating layer 173, and the base insulating layer 173 is covered by an additional insulating layer 174. In Embodiment 2, the second layer additional insulating layer is formed of an ins...

Embodiment approach 3

[0097] Figure 16 It is a schematic diagram showing an insulating layer structure of a heater unit according to Embodiment 3 of the present invention. In the third embodiment, the insulating structure of the heater unit 240 is different from the case of the first embodiment. Further, in the third embodiment, in particular, the unmetrified items are also described in the same, and the same reference numerals are described in the same functions and structures.

[0098] For the heater 241, the three resistance lines 272 are wound around the core line 271 and coated with an additional insulating layer 274, and the additional insulating layer 274 is further coated by an additional insulating layer 275. Here, each of the resistance lines 272 wound around the core line 271 is covered by the base insulating layer 273. Since the resistance line 272 is fine, it is difficult to form the base insulating layer 273 by extrusion molding. In this case, the base insulating layer 273 can be coated ...

Abstract

The refrigerating refrigerator of the present invention includes: a refrigerator main body having an opening and forming a storage room; two freely openable and closable doors arranged in parallel with the opening; The gap extends and closes the gap from the side of the storage room, and the partition plate has: a surface part, which is opposed to the door; a heater unit, which has a linear heater arranged to an end of the surface part, and the heater has: A heat generating part that generates heat by energization; and a basic insulating layer that covers the heat generating part, and two or more additional insulating layers are provided between the basic insulating layer and the surface member.

Description

Technical field [0001] The present invention relates to a refrigerator comprising a refrigeration door is off. Background technique [0002] In recent years, in the refrigerator cooling, the refrigerator door sealing gap between the partition plate mounted in the heater unit, the heater is energized according to the ambient room temperature and humidity, thereby to suppress condensation of the partition plate (e.g., Referring to Patent Document 1). In Patent Document 1, by using a member made of a synthetic resin as the surface of the separator member, thereby suppressing generation due to the temperature of the portion provided with the gasket between the door and the partition plate caused by decrease in contact condensation. However, the surface of the synthetic resin member is easily deformed in the height direction, in order to strengthen the reinforcing plate is required, so that the structure of the partition plate becomes complicated. [0003] However, the temperature in ...
