BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling storage in which a cooling duct for covering a cooler can be detachably mounted on a cooling storage main body.

[0002]

2. Description of the Related Art Conventionally, various types of cooling storages of this kind have been proposed. The cooling duct (cooling duct) disposed above the inner box is formed with a stopper and an overhanging edge at the upper end of the cooling box (cooling duct). A refrigerator is described in which an edge is supported by a receiving edge of an inner box and a stopper is locked by a locking projection. According to such a refrigerator, the cooling duct can be easily attached to and detached from the upper part of the inner box, so that maintenance and inspection of the cooler unit and the like can be easily performed.

[0003]

Generally, the cooling unit is provided with an evaporator (evaporator), a fan motor for circulating air cooled by the evaporator in the refrigerator, and the like. Vibration is generated from the cooling air, and the vibration is transmitted to the cooling duct.

However, in the conventional refrigerator, the cooling duct is positioned above the inner box in a direction opposite to the direction in which the stopper of the cooling duct and the locking projection of the inner box are locked. Is not provided at all.
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 jump out in a direction opposite to the locking direction due to the vibration. It is. When the cooling duct protrudes in this manner, the evaporator and the like are exposed in the refrigerator, and there is a risk that a finger may touch the evaporator or the like when taking out or supplying foods or the like, and the user may be injured.

[0005] Generally, in a refrigerator, moisture in the air cooled by the cooler is liable to form dew on the surface of the cooling duct. Dew condensation generated on the surface of the cooling duct as described above may adversely affect foods and the like in the refrigerator.

The problem associated with the condensation can be solved by attaching a heat insulating material to the surface of the cooling duct. However, in the above-described conventional refrigerator, the heat insulating material is not provided on the surface of the cooling duct. Here, even if a heat insulating material is stuck to the surface of the cooling duct, the cooling duct is attached to and detached from the inner box by sliding the overhanging edge and the receiving edge at 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 slides inside the receiving edge.

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

[0008]

In order to achieve the above object, the present invention provides a cooler fixed to the lower surface of an upper wall of a cooling storage body, and a cover formed in a tubular shape with both sides open and covering the cooler. And a pair of guides, one end of which is open and the other end of which is closed, is fixed to the lower surface of the upper wall. A base member having the cooler attached thereto, a heat insulating material disposed on a surface of the cover member, and formed at an upper end of the cover member by being bent inward from the surface, A pair of slide portions that are slidably inserted from the open side of the guide portion, and correspond to the open side of the guide portion when the cover member is attached to the base member via the slide portions and the guide portion. It is configured to include a guard member disposed on one side of the cover member.

[0009]

In the present invention having the above structure, first, the base member is fixed to the lower surface of the upper wall of the cooling storage body, and
A cooler is attached to the base member. Thereafter, the slide member formed on the cover member having the heat insulating material disposed on the surface is inserted from the open side of the guide portion provided on the base member, so that the cover member is disposed at a position covering the cooler. Is done.

At this time, since the slide portion formed at the upper end portion of the cover member is formed by being bent inward from the surface thereof, the heat insulating material on the surface of the cover member at the time of the insertion is formed. It does not peel or tear. Further, at the cover position of the cooler, the end of the slide member is in contact with the closed side of the guide portion, and the cover member is positioned in the insertion direction.

After disposing the cover member in this manner, a guard member is disposed on one side of the cover member corresponding to the open side of the guide portion of the base member. The cover member is positioned in a direction opposite to the insertion direction via the guard member. Thus, even if vibration occurs during cooling by the cooler, the cover member does not move.
