Therefore, when the vibration from the fan motor or the like is transmitted to the cooling duct as described above, there is a possibility that the cooling duct may pop out in the direction opposite to the locking direction due to the vibration. Is. If the cooling duct pops out in this way, the evaporator and the like are exposed in the refrigerator, and there is a risk that fingers may come into contact with the evaporator and the like during the extraction and supply of food, resulting in injury.

Further, generally, in a refrigerator, water in the air cooled by the cooler is likely to be condensed on the surface of the cooling duct. Condensation formed on the surface of the cooling duct in this way may adversely affect the food in the refrigerator.

The problem associated with such dew condensation can be solved by pasting a heat insulating material on the surface of the cooling duct, but in the conventional refrigerator, the heat insulating material is not provided on the surface of the cooling duct. Here, even if a heat insulating material is attached to the surface of the cooling duct, the cooling duct is slidably attached to and detached from the inner box by sliding the projecting edge and the receiving edge of the upper part of the inner box as described above. Therefore, there is a problem that the heat insulating material may be peeled off or the heat insulating material may be broken at a portion where the overhanging edge is in sliding contact with the receiving edge.

The present invention has been made to solve the above-mentioned problems of the prior art, and it is possible to prevent the cooling duct from moving even when vibration occurs during cooling by the cooler, and to prevent the cooling duct from moving. An object of the present invention is to provide a cooling storage that can prevent the heat insulating material provided on the surface of the cooling duct from being peeled off or damaged even when it is attached to or detached from the cooling storage main body.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention comprises a cooler fixed to the lower surface of the upper wall of the cooling storage body, and a cover member that is formed in a tubular shape with both sides open and covers the cooler. In a cooling storage cabinet that is detachably attached to the lower surface of the upper wall, a pair of guide portions with one end open and the other end closed is provided, and is fixed to the lower surface of the upper wall and the cooler is attached. A base member, a heat insulating material attached to the front surface of the cover member, and an upper end of the cover member that is bent inward from the surface and formed from the open side of the guide portion. One side of the cover member that corresponds to the open side of the guide part when the cover member is attached to the base member via the pair of slide parts slidably fitted and the slide parts and the guide part.
