no. 3 Embodiment approach

[0125] In the refrigerator according to the third embodiment of the present invention, the detection performance of the indoor illuminance is improved by installing an illuminance sensor in the handle structure of the heat-insulating door formed by the side-by-side door, which is used below. Figure 20 Be explained. In addition, other structures are the same as the refrigerator of the previous 2nd Embodiment of this invention except the installation position of an illuminance sensor, and the same code|symbol is attached|subjected and description is abbreviate|omitted.

[0126] Such as Figure 20 As shown, a unit frame 83 is assembled to a part of the handle portion 60a. A sensor substrate 84 is fixed to the unit frame 83 by screws 85 , and the illuminance sensor 81 provided on the sensor substrate 84 is disposed downward. The lower end surface of the unit frame 83 has a window 86 at a position facing the upper inclined surface 62b of the insulating door 62 formed by the draw...

Abstract

A refrigerator is provided with heat-insulating doors (10, 11, 12) which can open and close the storage chambers, respectively, of the refrigerator body. The front surface of each of the heat-insulating doors (10, 11, 12) is constructed from a transparent front plate (25) equipped with a colored layer and having an exposed outer periphery. The grip (10a) of the heat-insulating door (10) is formed in a recessed manner in either the upper end surface or the lower end surface of the edge frame of the heat-insulating door (10). Although the refrigerator is provided with the multiple heat-insulating doors (10, 11, 12), the transparent front plate (25) is directly exposed at the outer periphery of each of the heat-insulating doors (10, 11, 12), there is no protrusion at the outer periphery, and the grip (10a) does not protrude from the front face of the transparent front plate (25).

Description

technical field [0001] The present invention relates to a refrigerator, in particular to a door structure of the refrigerator. Background technique [0002] Generally, such a refrigerator includes a refrigerator, a freezer, and a freezer in a heat-insulating refrigerator body, and each of the refrigerators, freezers, and freezers is configured to be openable and closable by a door. [0003] The door is configured to be filled between the front panel as the front surface of the refrigerator main body, the inner frame as the inner surface of the refrigerator compartment, the freezer compartment, the freezer compartment, etc., and the frame that integrally connects these front panels and the inner frame. Polyurethane foam has the same heat insulation performance as the main body of the refrigerator. [0004] In such a refrigerator, the front panel of the door has a great influence on the aesthetic appearance of the entire refrigerator, that is, an external design, and its degr...
