System and method for driving a drawer in a refrigerator

Abstract

The present disclosure relates to a system and method for driving a drawer of a refrigerator. In a system and method for driving a drawer of a refrigerator according to present embodiments, the drawer is always withdrawn or inserted at a preset speed regardless of the weight of food stored inside the storage box, thus increasing reliability of the drawer driving system.

Description

technical field [0001] The present disclosure relates to systems and methods for actuating refrigerator drawers. Background technique [0002] In general, a refrigerator is a home appliance for storing food in a refrigerated or frozen state. [0003] In particular, refrigerators may be mainly classified into top-freezing type, bottom-freezing type, and side-by-side refrigerators depending on respective locations of the freezing chamber and the refrigerating chamber. [0004] The freezer compartment is placed below the refrigerator compartment in the bottom freezer configuration. A door for opening and closing the refrigerating compartment is provided to be pivotable about an edge of the body, and a door for opening and closing the freezing compartment is provided in a storage box door configuration that moves back and forth. [0005] Since the freezer is provided under the refrigerating chamber, the user has to stoop to grab the door and pull the door forward in order to o...

Problems solved by technology

[0015] Second, the time it takes for the controller to sense the movement and actuate the drawer drawer is too much compared to the time it takes for the user to grab the handle and pull the drawer forward, thus reducing utility

That is, when the motion to withdraw the storage box is performed, the response speed of the storage box withdrawal mechanism is very slow, so the user may not perceive any improvement in convenience

[0016] Third, since the drawer of the storage box only pushes the storage box far enough to separate it from the main body of the refrigerator, there is a limitation after which the user must directly grasp the handle and then pull the storage box forward

[0019] Second, if the drive motor and gear assembly were to be mounted inwardly into the inner shell of the refrigerator, this could trigger a limitation of insulation losses within the refrigerator body

[0023] Fifth, in the related art refrigerator equipped with a motor fixedly installed on the bottom plate of the refrigerator main body to draw out the storage box, there is no accompanying function of monitoring and controlling the storage box extraction speed during the storage box extraction process

Therefore, there are limitations in that it is impossible to sense whether the storage box is being drawn out at a normal speed, whether there is an obstacle preventing the storage box from being drawn out, and whether the storage box is being drawn out at a set speed regardless of the weight of food stored therein.
