Benefits of technology

[0009] An object of the present invention is to provide a refrigerator which can elevate a compartment provided at a lower portion of the refrigerator when the door is open for the user's convenience and a mechanism for electrically connecting a device for elevating the compartment with the body.
[0011] Another object of the present invention is to prevent a conductor electrically connecting the electrical device with the body from being damaged by a movement of the door or other parts of the refrigerator.
[0021] Alternatively, the winding device may include a reel around which the conductor is wound, and a mechanism for rotating the reel to wind or unwind the conductor when the electrical device moves along the first direction. The mechanism may include a rack arranged along the first direction, and a pinion engaged with the rack and secured to the reel. The reel may extend from a lateral side of the pinion. The conductor may be arranged to pass through the reel to be wound around the reel when the reel rotates. The reel may be located at a middle portion of the conductor when the conductor extends to a maximum length in the first direction so that the reel can wind the conductor at both sides of the conductor at the same time.

Problems solved by technology

Meanwhile, it is very uncomfortable for the user to use the freezing compartment mounted at the lower portion of the refrigerator when the door is simply open by rotating about the hinge, because the user has to kneel and bend his or her body and stretch his / her hands into an inside of the freezing compartment mounted on the lower portion of the refrigerator.

first embodiment

[0059] Referring to FIGS. 2, and 4 to 7, the winding device 200a according to the present invention includes a reel 210 around which the conductor 100 is wound, and an elastic member 220 providing the reel 210 with a rotating force by an elastic force. The reel 210, for example, has a cylindrical shape and the conductor 100 is wound around an outer circumferential surface of the cylindrical reel 210 while the reel 210 rotates. The reel 210, for example, has a space therein, and the elastic member 220 is disposed in the space as shown in FIG. 4. The elastic member 220 may include a wind-up spring which accumulates the elastic energy therein while being wound or unwound according to the rotating movement of the reel 210.

[0060] A first end of the elastic member 220 may be connected to the reel 210 and a second end of the elastic member 220 may be connected to the body 10 and vice versa. Alternatively, the first end of the elastic member 220 may be connected to the reel 210 and the seco...

second embodiment

[0070] Meanwhile, referring to FIGS. 8 to 11, the winding device 200b in accordance with the present invention includes a reel 260 and a mechanism for rotating the reel 260. The mechanism rotates the reel 260 clockwise or counterclockwise according to the movement of the electrical device or the door 13 so that the conductor 100 is wound around or unwound from an outer circumferential surface of the reel 260 when the electrical device or the door 13 moves.

[0071] The conductor 100 may be unwound from the reel 260 while the reel 260 rotates in the clockwise direction by the mechanism in the illustrated embodiment when the electrical device or the door 13 moves forward with respect to the body 10. On the contrary, the conductor 100 may be wound around the reel 260 while the reel 260 rotates in the counterclockwise direction by the mechanism when the electrical device or the door 13 moves backward with respect to the body 10. The detailed structure of the reel 260 and the mechanism now ...

Abstract

A refrigerator includes a body having a compartment in the body and a door for opening and closing the compartment, an electrical device movable with respect to the body along a first direction, a conductor electrically connecting the electrical device with the body, and a winding device for adjusting a length of the conductor in the first direction when the electrical device moves along the first direction.

Description

[0001] This Nonprovisional application claims priority under 35 U.S.C. §119(a) on Patent Application No. 10-2004-0085689 filed in Korea on Oct. 26, 2004 and Patent Application No. 10-2004-0093111 filed in Korea on Nov. 15, 2004, the entire contents of which are hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a refrigerator, and more particularly, to a mechanism electrically connecting a body of the refrigerator with an electrical device which is mounted on a door or a part of the refrigerator movable with respect to the body of the refrigerator. [0004] 2. Discussion of the Related Art [0005] Conventional refrigerators are usually classified into three types, i.e., a top mount freezer type, a side by side type, and a bottom mount freezer type. In the top mount freezer type refrigerator, a freezing compartment is provided on an upper portion of the refrigerator and a refrigerating compartment is pro...
