An accommodation portion 147 configured to accommodate food items therein may be provided at a rear surface of the freezing chamber door 145. The accommodation portion 147 may be integrally formed with the freezing chamber door 145. The accommodation portion 147 may be formed to have a height lower than that of the freezing chamber 140. A drawer 160 may be provided at an inner upper region of the freezing chamber 140 so as to be withdrawn in back and forth directions.
The drawer 160 may be formed in an upwardly-opened box shape, and may be configured to have a width in right and left directions corresponding to a width of the freezing chamber 140 in right and left directions. Sliding supporting portions 163 configured to slidably support the drawer 160 may be provided at both side walls of the freezing chamber 140. In the preferred embodiment, the sliding supporting portions 163 are implemented as rails 163. Alternatively, the sliding supporting portions 163 may be implemented by providing a roller (not shown) at the drawer 160, and by providing a roller supporting portion configured to support motion of the roller, at side walls of the freezing chamber 140 and/or an upper end of the accommodation portion 147.
The connecting member 170 configured to slide the freezing chamber door 145 and the drawer 160 in an interworking manner with each other may be provided between the freezing chamber door 145 and the drawer 160. More concretely, when the freezing chamber door 145 is withdrawn, the drawer 160 may be pulled by the connecting member 170 to be withdrawn together with the freezing chamber door 145. Accordingly, the freezing chamber door 145 and the drawer 160 may be simultaneously opened by one operation to open the freezing chamber door 145.
The connecting member 170 may be provided at the freezing chamber door 145.
As shown in FIGS. 3 and 4, the connecting member 170 may include a body 171 having one end connected to the freezing chamber door 145, and a hooking portion 181 formed to be bent at another end of the body 171.
The body 171 may be formed in a rectangular plate shape. A hinge pin 175 may be provided at one end of the body 171. The hinge pin 175 may be implemented in plurality in number. Each of the hinge pins 175 may have one end connected to the body 171, and another end formed to be bent.
The connecting member 170 may be coupled to an upper central part of a rear surface of the freezing chamber door 145. A connecting member supporting portion 151 configured to rotatably support the connecting member 170 may be formed at the freezing chamber door 145. The connecting member supporting portion 151 may be provided with hinge pin holes 152 formed at both ends thereof so as to rotatably insert the hinge pins 175 thereinto.
The connecting member 170 may be coupled to the connecting member supporting portion 151 so that the hooking portion 181 can be toward the lower side when the body 171 is horizontally arranged. Since the hooking portion 181 is arranged so as to contact a rear side of a front surface of the drawer 160, the hooking portion 181 forwardly pulls the front surface of the drawer 160 when the freezing chamber door 145 is withdrawn. As a result, the drawer 160 is forwardly withdrawn.
An insertion portion 155 configured to insert the hooking portion 181 of the connecting member 170 thereinto may be provided at a lower side of the connecting member supporting portion 151. The insertion portion 155 may be implemented as a slot configured to insert the hooking portion 181 thereinto.
When the connecting member 170 is not used, the hooking portion 181 may be inserted into the insertion portion 155 by downwardly rotating the connecting member 170. Accordingly, the connecting member 170 is not protruding form a rear surface of the freezing chamber door 145, but is fixed into the insertion portion 155 not to be moved. This may prevent interference between the connecting member 170 and the periphery.
Hereinafter, the operation of the connecting member 170 will be explained with reference to FIGS. 5 and 6.
When the freezing chamber door 145 and the drawer 160 are to be interworked with each other, as shown in FIG. 5, the connecting member 170 is upwardly rotated to arrange the hooking portion 181 on a rear side of a front surface of the drawer 160. Under this state, once the freezing chamber door 145 is forwardly pulled to be withdrawn, the front surface of the drawer 160 is forwardly pulled by the hooking portion 181. Accordingly, the drawer 160 is withdrawn to the front side of the freezing chamber 140 in a sliding manner. This may allow the drawer 160 to be simultaneously forwardly withdrawn when the freezing chamber door 145 is opened, without requiring to forwardly withdraw the drawer 160 after opening the freezing chamber door 145.
On the contrary, when only the freezing chamber door 145 is to be withdrawn while the drawer 160 maintains an accommodated state in the freezing chamber 140, as shown in FIG. 6, the connecting member 170 is upwardly rotated to separate the hooking portion 181 from the drawer 160. Then, the connecting member 170 is downwardly rotated to contact the body 171 to a rear surface of the freezing chamber door 145. Since the hooking portion 181 is in an accommodated state in the insertion portion 155, interference of the connecting member 170 with the periphery may be prevented. Under this state, once the freezing chamber door 145 is forwardly pulled to be withdrawn, only the freezing chamber door 145 is forwardly withdrawn while the drawer 160 maintains an accommodated state in the freezing chamber door 140.
Hereinafter, a refrigerator according to another embodiment of the present invention will be explained in more detail with reference to FIGS. 7 to 10.

The wire coupling portion 213 may be formed of an elastic member (e.g., synthetic resin member) which is elastically transformed so that the opening 214 can be outwardly widened when coupling the wires to the wire coupling portion 213 or when detaching the wires from the wire coupling portion 213.
Sizes of the wire coupling portion 213 and the opening 214 may be formed to correspond to diameters of the horizontal wires 192 or the vertical wires 194. In the preferred embodiment, the connecting member 210 is coupled to the horizontal wires 192 so as to be rotatable in upper and lower directions, the horizontal wires 192 horizontally arranged at an upper part of a front surface of the drawer 190.
A contact portion 230 configured to couple the hooking portion 221 of the connecting member 210 thereto, and to maintain the coupled state in back and forth directions may be provided at a rear surface of the freezing chamber door 145.
The contact portion 230 may be implemented as a hook ring 230 protruding from a rear surface of the freezing chamber door 145. The hook ring 230 may be formed in a ‘U’ shape. Alternatively, the contact portion 230 may be implemented as a recess concavely formed at an upper surface of a protrusion so that the hooking portion 221 can be inserted thereinto by a predetermined depth from an upper side to a lower side, the protrusion formed at a rear surface of the freezing chamber door 145.
Hereinafter, the operation of the connecting member will be explained with reference to FIGS. 9 and 10.
When the drawer 190 is to be interworked with the freezing chamber door 145, as shown in FIG. 9, the connecting member 210 is upwardly rotated, thereby coupling the hooking portion 221 of the connecting member 210 to the contact portion 230 of the freezing chamber door 145. Accordingly, the drawer 190 is interworked with the freezing chamber door 145 to be in a slidable state. Once the freezing chamber door 145 is forwardly pulled, the force applied to the freezing chamber door 145 is transmitted to the drawer 190 by the connecting member 210. Accordingly, the drawer 190 is withdrawn to the front side.
When the interworked state between the drawer 190 and the freezing chamber door 145 is to be released, as shown in FIG. 10, the connecting member 210 is upwardly rotated, thereby detaching the hooking portion 221 of the connecting member 210 from the contact portion 230 of the freezing chamber door 145.
The detached connecting member 210 is downwardly rotated with respect to the wires due to its self weight, thereby being in a vertical direction. Under this state, once the freezing chamber door 145 is forwardly pulled, only the freezing chamber door 145 is forwardly withdrawn while the drawer 190 is in an accommodated state in the freezing chamber 140.
In the present invention, the freezing chamber door is configured to be slidable, and the drawer is provided in the freezing chamber. However, the refrigerating chamber door may be configured to be slidable, and the drawer may be provided in the refrigerating chamber.
In the present invention, one drawer is formed in the freezing chamber. However, the drawer may be formed in plurality in number, and the plurality of drawers may be configured to be interworked with the freezing chamber door by the connecting member.
In the present invention, the accommodation portion of the freezing chamber door, and the drawer are arranged in upper and lower directions. However, the accommodation portion of the freezing chamber door, and the drawer may be spacing from each other in right and left directions.
In the preferred embodiment with reference to FIGS. 7 to 10, the connecting member is coupled to the horizontal wires of the drawer. However, the connecting member may be coupled to the vertical wires of the drawer.
As aforementioned, in the present invention, since the connecting member is configured to connect the door and the drawer to each other, the drawer is withdrawn when the door is withdrawn. This may enhance a user's convenience.
Furthermore, since the door is configured to be selectively interworked with the drawer, the door and the drawer are interworked with each other when using the drawer, while the door and the drawer are separately operated from each other when not using the drawer. This may also enhance a user's convenience.
