Seal for refrigerator door

The innovation relates to a seal for refrigerator doors and relates in particular to the attachment of this seal at the door.

There are several ways to attach the seals to refrigerator doors Systems known. Usually a lip of the sealing element is inserted between the outer and inner walls of the door and the sealing element is then for example by means of

Screws attached to the inner wall so that it is in the event of damage or wear can be exchanged by loosening the fastening elements. This type of attachment of the seal is permitted However, it is not possible to close the space between the outer and inner walls of the door by directly injecting polyurethane foam insulate, as in this case the seal can no longer be removed after the door outer wall and inner wall together with the polyurethane foam mass in between form an inseparable body. One must therefore use such a heat insulating material use which does not form a single body with the walls of the door, such as glass wool, but a smaller one Insulation value must be accepted as that which can be achieved when using polyurethane foam. If you want, however Use polyurethane foam anyway, then you have to use a more complicated one and more expensive manufacturing process, which consists in placing the polyurethane foam between the outer wall the door and an auxiliary molding is injected, after which the such shaped door the inner wall and seal is attached.

The disadvantages of this method can be eliminated by using a rigid profile element along the entire length of the door is attached and that a provided with a molded foot part Sealing element is used, the foot part of which is pressed into a groove of the rigid profile element. This type of attachment has different variants, one of which is that the rigid profile element between the inner and the Outer wall of the door is attached. In any case, the sealing element can also be used when using polyurethane foam as the insulation material exchange, but this solution is economical in view of the need to use an auxiliary profile element unfavorable.

The task of the innovation is to address the disadvantages of the previously mentioned to eliminate known ways of attaching the seal. According to the invention, this is comprised of a refrigerator door an outer and an inner wall and a foam insulating compound between these two walls achieved in that the Seal is provided with an elastically flexible foot part and a groove-shaped recess is provided on the circumference of the inner door wall into which the resilient foot part of the seal can snap into place.

Some embodiments of the hay are shown in the drawing, the Fig. I, 2 and 3 in section the edge of refrigerator doors show where the seal according to the invention is attached.

The refrigerator door consists essentially of an outer wall and an inner wall 11, the space between these two Walls is filled with a directly injected thermal insulation material 12, for example polyurethane foam.

On the circumference of the inner wall, a groove-shaped recess 13 is provided by appropriate shaping, into which the foot part 1h of the sealing element 15, which consists of a relatively elastically flexible material, can be snapped.

As FIGS. 1, 2 and 3 illustrate, the groove-shaped recess 13 can optionally have an undercut profile with a have inclined end portion in order to prevent undesired exit of the foot part of the seal, or it can by a corresponding curved peripheral portion of the inner wall 11 be formed,

an appropriate reinforcing profile element 16 also being present can be.

The seal according to the invention and its attachment to the refrigerator _{door eliminates any fastening elements 3} although the seal is removable and replaceable, the space between the outer and inner wall of the door being injected directly without the need for an additional profile element for attaching the seal Polyurethane foam filled in can. The execution is extremely simple in terms of both production and assembly.
