Description

[Detailed Description of the Invention] The present invention relates to the structure of a top-opening heat insulating door suitable for opening and closing the ice storage compartment of an ice maker, the refrigerating or freezing compartment of a refrigerator, etc.

In general, a top-opening heat insulating door for an ice maker, etc. has a heat insulating member attached to the back of the front panel and a handle for opening/closing on the upper surface of the panel. For conventional doors, it is necessary to provide sufficient rigidity and strength to prevent the panel from deforming or shaking the handle due to external forces acting on the handle when opening and closing. The structure had become significantly more complex due to improvements in the strength of the handle attachment and the like. In addition, conventional doors with handles attached to the surface of the front panel have a handle that protrudes from the front of the door, giving an impression of being complicated in appearance, and the range in which the hand can be placed on the handle is narrow, making it especially difficult to open the door. It is troublesome to properly engage the hand on the handle during operation.
They disliked the lack of operability.

The present invention was developed in view of the above-mentioned conventional circumstances, and is applicable to top-opening insulating doors in ice makers, refrigerators, etc., in which a heat insulating member is attached to the back of the front panel and a handle member is fixed to the top. In this case, the fixing part of the handle member on the front panel has a structure that is easy to manufacture and has excellent rigidity and strength, and the handle member is fitted from above with good assembly and strength, so that it can be used for a long period of time. The purpose of this invention is to provide an inexpensive door that does not cause deformation of the panel or rattling of the handle even when used with a heat insulating door, and also to realize a door with excellent decorativeness and operability as this type of insulated door. be.

For this purpose, the heat insulating door according to the present invention is constructed by bending the upper edge of the front panel between the notches formed near both ends to the back side, leaving protrusions at both ends. The bent portion is formed to have a concave shape when viewed from the front, and the upper surface of the handle member is shaped to have a concave portion except for both ends corresponding to the shape of the upper edge of the front panel. and the outer side of the door of the recess is formed to be higher than the inner side of the door in a stepped manner, and the groove in which the bent portion fits into the lower surface of the outer surface of the recess, and the protruding portion fits into the lower surface of both ends. The handle member is configured to be fitted upwardly into the upper edge of the front panel and fixed by forming matching slits respectively. As a result, the bending portion at the upper edge of the front panel increases the rigidity around the upper edge with an extremely simple structure, and by fitting the handle member into the upper edge from above, The bent portion, which fits into the groove on the lower surface of the outer surface of the recess, can maintain sufficient strength against an external force acting horizontally on the outer surface of the recess of the handle member during a door opening operation. The structure is such that the connection between the panel and the panel does not loosen easily, and as a result, a door that does not cause deformation of the panel or wobbling of the handle member even after long-term use is realized, and the handle member does not loosen easily. By being fitted into the upper edge, the appearance of the handle protruding from the front of the panel is eliminated, and the handle member has a simple and highly decorative appearance. By making the concave portion sufficiently wide, the door has excellent operability.

Embodiments of the present invention will be described below with reference to the drawings.

The upper edge 6 is bent into a U-shaped cross section to
By bending the semicircular notches a and the part b between the two notches a and a toward the back side along the line connecting the vertices of both the notches a and a, the bent portion 6a and both ends The remaining protrusions 6b, 6b form a concave shape when viewed from the front (or back). Here, in this embodiment, after the portion b between the notches a and a is bent 90 degrees to the back side, the tip thereof is further bent 90 degrees downward, so that the bent portion 6a has a cross section. Although it is said to be U-shaped, if the required rigidity is obtained, the above part b
It is sufficient to simply bend the groove 90 degrees to the back side, and the cuts a and a are not limited to semicircular shapes, but may also be V-shaped or the like.

Next, in FIG. 4, reference numeral 7 denotes a heat insulating member attached to the back surface of the front panel 3, and the left and right side edges and the lower edge of this member 7 are the left and right side edges 4 of the panel 3 bent in a U-shape. . Also, 9 is the front panel 3
A handle member 10, 10, which also serves as a decorative edging attached to the upper edge 6, is a side edging member attached to both left and right edges of the panel 3, and the upper surface of the handle member 9 is attached to the upper edge 6 of the panel. It has a concave shape with the parts excluding both end portions 9a, 9a recessed in accordance with the shape of the door, and the outer side 9b' of the recess 9b is stepped higher than the inner side 9b''. , and a bent portion 6a at the upper edge 6 of the front panel is provided in the groove 9c formed on the lower surface of the outer surface side 9b' of the recess, and a bent portion 6a is provided on the lower surface of both end portions 9a, 9a as shown enlarged in FIG. The protrusions 6b, 6b at both ends of the upper edge 6 of the front panel are fitted into the slits 9d, 9d, respectively, and in this state are coupled to the reinforcing member 8 with a plurality of screws 11, 11..., thereby the handle member 9 is fixed to the upper edge 6 of the panel 3. Furthermore, the side border member 1
