Problems solved by technology

[0020] In Patent Document 4, Patent Document 5, and Patent Document 6, although it is disclosed that there is a rotatable cam formed in an arc shape or an ellipse, by using a signal from a door opening switch to rotate the above-mentioned cam through a drive device, the size of the cam can be reduced. The end face of the diameter part protrudes forward to open the cam device of the door, but in the constitution of such prior art, the amount of pushing out the door when the cam rotates is only a part of the change of the radius of the cam as the cam rotates, so the amount of pushing out the door The speed given by the direction is low, and the amount of opening of the door is approximately equal to the amount of protrusion due to the action of the cam, that is, the driving range of the driving force given to the door, so that there is a limit to the further increase of the opening amount of the door.

Embodiment Construction

[0062] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0063] First, the overall structure of the refrigerator will be described.

[0064] FIG. 1 is a perspective view of a refrigerator according to the present invention, and FIG. 2 is a longitudinal sectional view. In Fig. 1 and Fig. 2, the refrigerator main body 1 is divided into a plurality of storage compartments, and the uppermost part is a refrigerator compartment 2, and its door is a so-called French door 2a that opens to the left and right sides as an example. The lower side of the refrigerating room 2 is a left and right storage room, for example, one of which is a function switching room 3, and the other is an ice making room 4 for storing or taking out ice made by an automatic ice making device not shown.

[0065] Its lower part is to have the freezer compartment 5 that pulls out to the front and can open the drawer door 5a, and the lowest floor is the structure...

Abstract

The present invention relates to refrigerators. The present invention can reduce malfunctions of refrigerators. A refrigerator having a drawer door that can be pulled out in the front-rear direction, wherein the drawer door has a door, door frames arranged on the left and right sides of the door, and reinforcing plates provided to connect the left and right door frames, and the drawer container is placed on the door frame Above, there is a door driving device for opening or closing the drawer container, the door driving device has a driving device installed on the main body side, and a connecting member receiving a driving force from the driving device provided at the lower part of the reinforcing plate.

Description

technical field [0001] The present invention relates to refrigerators. Background technique [0002] The device that opens the door of the refrigerator has a short-distance operation section with a high gear ratio and a short-distance operation section with a low gear ratio. When the liner is peeled off, a large force is generated, and then it opens at a high speed. A structure in which an overload prevention clutch is provided at a low gear portion is disclosed (for example, refer to Patent Document 1 - Japanese Patent Application Laid-Open No. 02-157581) [0003] Or, it is disclosed that the pressing member is linearly moved by a worm wheel and a rack, and the drawer door is pushed out by the pressing member to automatically open. If the door is opened, the return spring is used to return to the retracted position (for example, refer to Patent Document 2-Japanese Patent Publication No. 2001-280827). [0004] Alternatively, it is disclosed that a synchronous belt is set i...
