Description

Structure to prevent freezing of direct-cooling refrigerator

The present invention relates to a structure for installing a freezing prevention member of a direct-cooling refrigerator, and more particularly, when the freezing prevention member is installed on the side frame of the storage drawer of the direct-cooling refrigerator and the sliding surface of the EVA support member, the insertion and removal of the storage drawer. Due to the influence of EVA installed on the lower side of the storage drawer, the side frame of the storage drawer and the upper sliding surface of the EVA support member freeze, so that the insertion and removal of the storage drawer, which is likely to occur, can be easily inserted and removed without difficulty. It relates to a structure for installing an icing preventing member of a direct cooling refrigerator.

In general, home refrigerators are largely divided into a freezer compartment, a refrigerator compartment, and the like, and a rapid freezer compartment, a vegetable compartment, and the like are formed. Such a refrigerator is provided with a circulating device for refrigerant and a back duct and a collecting duct for circulating cold air, and the refrigerant circulating device includes a cooler, a compressor, a condenser, and the like.

As shown in FIG. 1, the direct-cooling refrigerator 10 for maximizing the freezing effect is provided by maximizing the freezing effect by installing an evaporator 14, that is, an evaporator in the freezing chamber 12. .

In this case, the evaporator 14 cools the surrounding storage by heat exchange that absorbs the latent heat of the liquid while the liquid refrigerant becomes a gas state at low temperature and low pressure. At this time, as the surrounding air becomes below the dew point, the released moisture develops sexually on the surface of EVA maintained at minus 30 ° C.

In addition, unlike the inner bead which protruded into the side wall 10 'of the refrigerator body in order to install and support the eva 14 in the freezer compartment 12, the eva support member 15 is attached to the side wall 10' of the freezer compartment 12. ) Is provided separately and used as a fastening screw (16), and at the same time serves to support the storage drawer (20) to be mounted, removable.

In this case, as shown in FIG. 2, the storage drawer 20 is inserted into or detached from the upper end of the EVA support member 40 symmetrically installed on both side walls 10 'of the refrigerator 10 and the freezing chamber 13. ) Is a stockpile portion 24 on which the object is stored, a rear end frame 21 on which the rear end of the stockpile portion 24 is fixed, and a front end frame on which the front end of the stockpile portion 24 is fixed. 22) and the side frame 23 for mounting, removing and supporting the storage drawer 20.

However, according to the method in which the storage drawer 20 is installed so that the storage drawer 20 of the conventional direct-cooling refrigerator 10 described above can be inserted and removed, the storage drawer 20 may be accommodated when the storage drawer 20 is inserted or removed. Due to the influence of the EVA 14 installed under the drawer 20, the sliding surface of the side frame 23 of the storage drawer 20 and the EVA support member 15 is frozen to insert the storage drawer 20. , Difficulty in detachment.

Therefore, the present invention is designed to solve the problems as described above, and the side frame of the storage drawer due to the effect of the EVA installed under the storage drawer to maximize the freezing effect of the insertion drawer, removable when the storage drawer, It is an object of the present invention to provide a structure for installing an icing preventing member of a direct-cooling refrigerator so that the sliding surface of the EVA supporting member is easily inserted into and detached from the storage drawer, which is easy to occur due to freezing.
