Embodiment Construction

[0026] figure 1 The freezer assembly is shown in cross section, as it is described in the prior art according to DE 10 2005 059 145 A1. The freezer assembly 50 is a component of a freezer which is not shown further. The freezer assembly 50 has a glass door generally indicated at 51 . In the closed state, the glass door bears against the door post 53 via the flexible seal 52 . The glass door 51 comprises, as a plurality of sheets of insulating glass, a panel complex 54 with three glass panels spaced apart from each other by means of spacer elements 55, namely the inner panel 3' close to the interior 56 of the freezer, the middle panel 4' and outer panel 5'. The middle plate 4' is located between the inner plate 3' and the outer plate 5'. The panel composite 54 is received at the edge by the vertically oriented door frame profile 2 ′. In this receiving area, the door frame profile 2 ′ is formed as an essentially U-shaped receiving groove 57 for the panel composite 54 . The...

Abstract

The invention relates to a door, in particular for a refrigerator and / or freezer, having a door frame (1) and at least two transparent panels (3, 4, 5), said door frame having polymeric door frame profile (2), the plates are arranged at a distance from one another parallel to the door frame plane and form here together with the door frame profile (2) at least one flat cavity filled with gas (6) (7, 8), wherein the plates (3, 4, 5) consist of a polymeric material.

Description

technical field [0001] The invention relates to a door, in particular for a refrigerator and / or freezer, having a door frame with a door frame profile and at least two transparent panels which are connected to each other They are arranged at a distance parallel to the plane of the door frame and form at least one flat cavity filled with gas. Background technique [0002] Such doors are used in particular in refrigerated installations for food retail. Such a door should on the one hand keep the energy consumption of the refrigerator or freezer low by good thermal insulation and on the other hand allow the customer to have a direct view of the contents of the appliance even when the door is closed. In this case it is of particular interest that the transparent plate is not covered by condensation, whereby the visibility of the goods and the overall appearance of the goods offer is affected. In particular, there is a danger of condensation forming on the relatively cool surfa...
