Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

Figure 2 is a perspective view of a refrigerator according to an embodiment of the present invention, Figure 3 is a partial cutaway cross-sectional view showing the winding portion at the time of withdrawal of the door of Figure 2, Figure 4 is an enlarged view of the winding portion of FIG. 5 is a view illustrating a winding part when the door of FIG. 2 is closed. As shown in these drawings, the present refrigerator comprises: a refrigerator main body 110 having a plurality of cooling chambers 111 formed therein; Doors 135 and 145 installed in one of the cooling chambers 111 so as to slide along the front and rear directions; A wire 157 extending from the refrigerator main body 110 to at least one of the doors 135 and 145; It is comprised including the winding part 160 which wound the said wire 157.

The refrigerator main body 110 has a plurality of cooling chambers 111, that is, a refrigerator compartment 112 and a freezer compartment 132, and stores foods with an internal temperature range different from that of the refrigerator compartment 112 and the freezer compartment 132. The switching room 142 is provided. The refrigerating chamber 112 is formed in an upper region of the refrigerator main body 110, and the refrigerating chamber 112 is provided with a pair of refrigerating chamber doors 115.

Among the refrigerator compartment doors 115, the right side refrigerator compartment door 115 is provided with a groove bar 117, and the refrigerator compartment door 115 on the left side has a dispenser 119 to draw water or ice. . One side of the dispenser 119 sets temperature conditions of the refrigerating chamber 112 and the freezing chamber 132, and a main operation panel 121 for operating the dispenser 119 is provided.

The freezing chamber 132 is formed below the refrigerator body 110, and the switching chamber 142 is formed above the refrigerating chamber 112. The freezing chamber 132 and the switching chamber 142 are provided with a freezing chamber door 135 and a switching chamber door 145 so as to slide out along the front and rear directions of the refrigerator main body 110. Baskets 137 and 147 are provided at the rear of the freezing chamber door 135 and the switching chamber door 145 to accommodate food.

On the other hand, the switching chamber door 145 is an outer plate 146a forming an outer appearance, an inner plate 146b spaced apart from each other at a filling interval of a foam material inside the outer plate 146a, and the outer plate 146a and And an upper cap 146c disposed at the upper end of the inner plate 146b and a lower cap 146d disposed at the lower end of the outer plate 146a and the inner plate 146b. Both sides of the switch chamber door 145 are coupled to a rail 144 supporting the switch chamber door 145 to be slidably withdrawn and stored.

The upper cap 146c is provided with a switching room operating panel 151 to set the temperature conditions of the switching room 142 and the like. This means that when the operation button and the display unit for setting the temperature conditions of the switching room 142 are integrally formed on the main operation panel 121, the number of the operation buttons 125 of the main operation panel 121 is increased and the display is displayed. This is to reduce the possibility of misoperation due to the increase in the amount of visual information displayed in the unit 123. A display unit 153 is formed in the central area of the switch room manipulation panel 151 to display visual information, and a plurality of operation buttons 155 are provided around the display unit 153.

One end of the switching room operation panel 151 may be connected to the control unit 185 provided in the refrigerator main body 110 so that a signal input from the switching room operation panel 151 may be transmitted to the control unit 185. The other end of the wire 157 is connected. A winding portion 160 is formed at one side of the switching room door 145 to wind the wire 157.

The winding unit 160 includes a winding reel 171 in which the wire 157 is wound around the winding reel 171, and the winding reel 171 in a direction in which the wire 157 is wound around the winding reel 171. It is provided with a reel driving unit for rotating.

The wound reel 171 is accommodated in the casing 161 forming an accommodation space therein, the casing 161 is the interior of the switching room door 145, that is, the outer plate 146a and the inner plate 146b. ) Is placed between.

The casing 161 includes a casing body 162 that forms an accommodation space having one side opened therein, and a cover 164 coupled to block the opening of the casing body 162. A through hole 166 is formed at one side of the casing body 162 to allow the wire 157 to pass therethrough, and the winding reel 171 is formed inside the casing body 162 and the cover 164. Rotational support 167 is formed to support the rotatably. As shown in FIGS. 4 and 5, the rotation support part 167 formed on the cover 164 is formed to communicate with the outside to allow the wire 157 to be drawn out.

The wound reel 171 has a predetermined diameter and has a body 172 of a circular cross section in which the wire 157 is wound around, and a flange extended outward along a radial direction on both sides of the body 172. 174 and rotation shafts 176 formed at both ends of the body 172. The rotation shaft 176 is rotatably supported by the rotation support 167, respectively. A space portion 178 is formed at one side of the rotation shaft 176 to allow the wire 157 to pass therethrough. One side of the space 178 is formed to communicate with the outer surface of the body 172 so that the wire 157 can be wound on the outer surface of the body 172. One end of the wire 157 is connected to the switching room operation panel 151 and the other end passes through the space part 178 to be wound around the outer circumferential surface of the body 172, and then penetrates the casing body 162. It is drawn out to the outside through the ball 166 and is connected to the refrigerator body 110.

The other one of the rotating shaft 176 of the winding reel 171 is provided with a coil spring 182 as a reel driving unit for rotating the winding reel 171. Here, the reel driving unit may be configured of an electric motor. A spring receiving portion 179 is formed in the rotating shaft 176 to accommodate the spring 182, one end of the spring 182 is fixed to the wound reel 171 and the other end is It is fixed to the casing 161. As a result, the spring 182 rotates the wound reel 171 when the switching chamber door 145 is stored with the elastic force accumulated when the switching chamber door 145 is pulled out, and thus, the circumference of the body 172 is rotated. The wire 157 is wound.

By this configuration, when the user wants to set the temperature condition of the switching room 142, the switching room operating panel 151 is separated from the main operation panel 121 and installed in the switching room door 145. ) Can easily set the temperature conditions of the switching room 142 without excessive attention.

On the other hand, when the switching chamber door 145 is drawn out, the wound reel 171 is rotated while the wire 157 wound around the wound reel 171 is released. At this time, one end of the spring 182 fixed to the winding reel 171 rotates together to accumulate elastic force.

When the switching chamber door 145 is closed, the winding reel 171 is rotated by the elastic force of the spring 182, whereby the wire 157 is wound around the winding reel 171.

In the above-described and illustrated embodiments, the case where the switching room operating panel and the winding part are formed in the switching room is described as an example, but the winding part may be provided in the refrigerator main body.

In addition, in the case of constructing a basket lift device for elevating the basket accommodated on the back of the door of the freezer compartment, the operation unit for operating the basket lift device on the door of the freezer compartment and the wire connected to the operation unit to be wound by the winding unit It can also be configured.
