Description

{DOOR FOR REFRIGERATOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door for a refrigerator, and more particularly, to a door for a refrigerator in which service can be facilitated without deteriorating the appearance quality.

As is well known, a refrigerator is a device that allows a food to be stored in a frozen state or a refrigerated state for a longer period of time.

The refrigerator may include a refrigerator body having a cooling chamber and a door for opening and closing the cooling chamber. The refrigerator body may be provided with a refrigeration cycle for supplying cold air to the cooling chamber.

The refrigerator body may be provided with a plurality of cooling chambers.

The cooling chamber may include a freezing chamber and / or a refrigerating chamber.

The door may be rotatably installed on a front surface of the cooling chamber.

Further, the door may be formed of a drawer-type door slidable along the front-rear direction of the cooling chamber.

The drawer-type door may be mainly composed of a freezer compartment door that opens and closes the freezer compartment.

On the other hand, since the temperature of the freezing compartment door is relatively low, pressure may be lowered due to contraction of the air, etc., so that a larger force may be required when the door is opened. Particularly, in a drawer-type door of a freezer compartment of a large refrigerator, opening of the door may become difficult due to the weight of the door itself, the weight of the food stored in the door, the pressure drop caused by the contraction of the air,

In consideration of such a problem, there is a door for a refrigerator in which a pusher is protruded and retracted by interlocking with a handle of a door, and a pusher is protruded when the handle is pulled to open the door so that the door can be easily opened .

1 is a view showing an example of a conventional door for a refrigerator.

1, the refrigerator may include a refrigerator body 10 having a cooling chamber 20 and a door 25 for opening and closing the cooling chamber 20.

The cooling chamber 20 may include a freezing chamber 21 and a refrigerating chamber 22.

A refrigerating chamber door 26 is provided on the front surface of the refrigerating chamber 22 and a freezing chamber door 31 is provided in the freezing chamber 21.

The freezing chamber door 31 may include a door body 33 and a handle 35 disposed on the front surface of the door body 33.

Meanwhile, the handle 35 may be configured to be rotatable with respect to the door main body 33.

A pusher 37 protruding rearward from the door main body 33 when the handle 35 is pulled to open the freezing chamber 21 may be provided on the inner surface of the door main body 33. [ The pusher 37 protrudes from the door body 33 and comes into contact with the rim of the opening of the cooling chamber 20 or the freezing chamber 21 so that the door body 33 is separated from the cooling chamber 20 Lt; / RTI > Thus, the opening of the door body 33 can be facilitated.

A power transmission unit (not shown) may be provided in the door main body 33 to transmit a driving force to the pusher 37 when the handle 35 is pulled.

However, in the conventional door for a refrigerator, the power transmission unit is configured to surround the refrigerator body 33 by a foaming agent, so that repair can not be performed in the event of a failure, and the refrigerator door itself must be replaced.

Considering such a problem, there is a door for a refrigerator in which a power transmitting portion can be inspected and repaired during use.

2 is a view showing another example of a conventional door for a refrigerator.

2, the door 40 for the refrigerator includes a door main body 41, a handle 45 rotatably provided on the front surface of the door main body 41, And a power transmitting portion (not shown) for transmitting a driving force acting on the handle 45 to the pusher 47 in the door main body 41, .

The protrusion insertion portion 182 may be formed with a through hole 183 to allow the coupling member 220 to be inserted therein. The power transmission unit case 170 may be provided with a female screw member 184 so that a fastening member 220 passing through the through hole 183 can be screwed. The female screw member 184 may be formed of, for example, a separate member (for example, a metal member) and disposed at the rear (rear surface) of the projection insertion portion 182 of the power transmission unit case 170 .

The lever 191 can be pivoted forward about the pivot shaft 194 when the handle 141 is gripped and pulled forward to open the freezing chamber 122. [

When the lever 191 is rotated forward, the arm 230 disposed behind the lever 191 may be rotated. More specifically, when the first arm 234 disposed at the rear of the lever 191 is pulled forward, the second arm 236 can be pivoted rearward about the pivot 233.

When the second arm 236 is rotated backward, the slider 240 can be slid rearward. Accordingly, the pusher 151 can protrude from the rear of the door main body 131. The pusher 151 protruding from the door body 131 may contact the rim of the front opening of the freezing chamber 122 to press the door body 131 in the opening direction. Thus, the opening of the door body 131 can be facilitated.

When the pulling force of the handle 141 is released, the handle 141 and the pusher 151 can be returned to their initial positions by the arm 230 that returns to the initial position by the elastic force of the return spring 237 have.

On the other hand, when the power transmission unit 190 is to be inspected, the handle 141 may be pulled forward to move the door body 131 in the opening direction.

The hook 153 of the pusher 151 is elastically deformed inwardly as the exposed end of the pusher 151 is pulled outward (in a direction away from the door main body 131) ) And released from the coupled state.

The handle 141 can be separated from the lever 191 when the pusher 151 is detached.

When the handle 141 is detached, the fastening member 220 coupled to the frame 210 may be exposed.

The engaging member 220 is separated and the frame 210 of the power transmitting unit 190 is held and moved in the lateral direction as opposed to the engaging of the frame 210 of the power transmitting unit 190. [

At this time, the contact protrusions 222 of the frame 210 are disposed between the support protrusions 179 and can be easily drawn out by horizontally moving the frame 210 forward. This makes it easy to check and / or replace the power transmitting unit 190.

The foregoing has been shown and described with respect to specific embodiments of the invention. However, the present invention may be embodied in various forms without departing from the spirit or essential characteristics thereof, so that the above-described embodiments should not be limited by the details of the detailed description.

Further, even when the embodiments not listed in the detailed description have been described, it should be interpreted broadly within the scope of the technical idea defined in the appended claims. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
