Refrigerator, system and method for driving a drawer of the 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 em not bodiments, when the drawer meets an obstacle during moving, the drawer immediately stops moving to secure the safety.

Description

technical field [0001] The invention discloses a refrigerator and a system and method for driving a refrigerator drawer. Background technique [0002] Generally, a refrigerator is a household appliance used to store food in a refrigerated or frozen state. [0003] Specifically, according to the respective positions of the freezing chamber and the refrigerating chamber, refrigerators can be mainly divided into top mount refrigerators, bottom freezer refrigerators, and side-by-side refrigerators. [0004] A bottom freezer configuration has a freezer compartment disposed below the refrigerator compartment. A door for opening and closing the refrigerating compartment is provided to be pivotable about one edge of the main 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 below the refrigerating chamber, in order to open the freezer, the user has to b...

Problems solved by technology

[0014] First, even in refrigerators provided with a device for separating the storage box from the main body, handles are required

That is, since the device is configured to detach the storage case from the main body only when the user grabs the handle and pulls the storage case forward, the handle is an essential component, and thus involves the aforementioned limitations

[0015] Second, the time it takes for the controller to sense this action and actuate the storage case extraction mechanism is too long compared to the time it takes for the user to grasp the handle and pull the storage case forward, thereby reducing practicality

That is, when the action of pulling out the storage box is performed, the reaction speed of the storage box withdrawing device is very slow, so the user does not feel any improvement in convenience.

[0016] Third, because the storage box extractor only pushes the storage box far enough to separate it from the main body of the refrigerator, it limits the user from having to grab the handle directly and then pull the storage box forward

[0018] First, in order to apply the above-mentioned structure to the refrigerator, the driving motor and gear transmission must be installed on the bottom plate of the refrigerator or freezer, so that the storage space in the refrigerator will be limited due to the volume occupied by the motor and gear transmission. was lowered

[0019] Second, if the drive motor and gear transmission are installed in the inner box of the refrigerator, this will bring about the limitation of insulation loss in the main body of the refrigerator

[0023] Fifth, in the prior art refrigerator configured to have a motor fixedly installed on the bottom plate of the refrigerator main body to draw out the storage box, there is no such additional function of monitoring and controlling the withdrawal speed of the storage box during the storage box extraction

Therefore, there are some limitations: it is impossible to sense whether the storage box is being withdrawn at a normal speed, whether the extraction of the storage box is blocked by an obstacle, and whether the storage box is being extracted at a set speed regardless of the food stored in it. how much weight
