Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a refrigerator, and more particularly to improvement of a cover of a cooling chamber.

(Prior Art) FIG. 4 shows the appearance of a refrigerator to which the present invention is applied. The refrigerator body 10 includes an upper freezing compartment 11, an ice making compartment 12, and a lower freezing compartment 1.
It is divided into 3, refrigerator room 14, vegetable room 15, and bottle room 16. Usually, a cooler is arranged behind the lower freezer compartment 13, and the upper and lower coolers are provided with a double inner / outer cover, and a cooling compartment including the cooler and an upper freezer compartment 11 and an ice making compartment 12 located in front of the cooling compartment. It is divided into. These two covers and the back surface of the cooling chamber form a duct through which cold air generated by the cooler passes.

(Problems to be solved by the invention) The duct formed by the two covers is a refrigerating room 14
(Not shown). The refrigerating compartment 14 normally stores humid items such as vegetables, and the doors are often opened and closed to allow high humidity outside air to enter. Then, such humid air contacts the front surface of the rear cover cooled by the cooler 20 to become fine frost and adhere. At the time of defrosting the cooler, the temperature of the duct rises, the frost forms water droplets, flows downward, and water accumulates at the joints at the lower ends of the two covers, which freezes due to cold air,
Furthermore, water falls on it and ice grows.

[Structure of the Invention] (Means for Solving the Problem) In the present invention, a plurality of horizontal ribs are provided vertically on the front surface of the rear cover of the both covers.

(Operation) A plurality of ribs share and receive water droplets attached to the front surface of the rear cover at the time of defrosting and the like, and are prevented from falling downward. When the cooling operation is started in this state, the cold air generated from the cooler comes into contact with the water droplets, and a small amount of ice is frozen in each rib. When this ice is continuously exposed to the passing cold air, the ice is vaporized by the sublimation phenomenon and is carried to the freezer compartment by the flow of the cold air.

(Embodiment) 11 is a freezing room provided at the top of the refrigerator body 10, and 12 is an ice making room therebelow. Behind these two chambers 11, 12 is a cooler 2
A cooling chamber 22 including 0 is located. Freezer 11 and ice maker 1
2 and the cooling chamber 22 are spaced apart from each other by 2
It is delineated by a sheet of covers 24,26. The cool air generated in the cooler 20 is forcibly sent forward by the fan 30 through the opening 28 at the upper end of the rear cover 24. This cold air is distributed to the freezing compartment 11 and the ice making compartment 12 in several stages by a plurality of slits 27 which are vertically provided on the front cover 26. Lateral ribs on the front of the rear cover 24
A plurality of 32 are provided vertically.

In the above device, the frost attached to the front surface of the rear cover 24 melts into dewdrops when defrosting, and the dewdrops flow downward and are gradually received by the plurality of ribs 32 as shown in FIG. Can be stopped. After that, when shifting to the cooling operation, the water droplets come into contact with the cold air f and become ice 34. Further, since the cold air f continuously contacts the ice 34, the ice is vaporized by the sublimation phenomenon and is carried away together with the cold air f.

In the illustrated embodiment, the rib 32 has a horizontal strip shape and both ends thereof are bent upward, so that it is possible to effectively receive water droplets, which is preferable. However, the form of the rib 32 is not limited to this, and any form can be adopted as long as it can easily receive a water drop and expose it to the cool air.

[Effects of the Invention] As described above, in the present invention, the ribs provided vertically on the front surface of the rear cover share and receive the water droplets in the cooling chamber, and freeze them by the cool air from the cooler. After that, the cold air is continuously contacted to remove this ice by the sublimation phenomenon, and it is possible to effectively prevent the water in the cooling chamber from dropping downward to freeze and grow.
