Embodiment Construction

[0018] figure 1 It shows a front view of a washing machine 1 provided with an open sealed round window 2 for closing the loading and unloading opening 3 .

[0019] figure 2 A preferred embodiment of the sealed round window 2 of the present invention is shown. The sealed round window 2 consists of a side wall 4 made of hard plastic and a base 5 made of mineral glass. The sight glass 10 has an inner surface 12 slightly raised toward the mouth of the cup. In the edge region 14 of the base 5 the sight glass 10 is bent towards the side wall 4 in such a way that a rounded glass shoulder 16 is formed. On the outer edge of the glass shoulder 16 , the sight glass 10 has a ring-shaped connecting portion 6 which runs obliquely relative to the inner surface 12 of the base 5 . The connecting part 6 opens into a top end 18 which has an annular projection 22 extending substantially parallel to the inner surface 12 of the bottom 5 .

Abstract

The porthole window is formed from a circular bottom section (5) and a sidewall section (4), whereby the bottom section (5) comprises a viewing glass (10) with an essentially planar inner surface (12) and a boundary region (14). The sidewall section (4) of the bowl, narrowing down towards the bottom section (5) is made from rigid plastic. The viewing glass (10) throughout the boundary region (14) of the bottom section (5) is bent in the direction of the sidewall section (4) in such a way that the boundary region (14) of the bottom section (5) forms a rounded glass shoulder (16). On the outer edge of the glass shoulder (16) the viewing glass (10) comprises an annular jointing section (6) running at an angle to the inner surface (12) of the bottom section (5), the head end (18) of which is fixed in engagement with the inner end (20) of the sidewall section (4).

Description

technical field [0001] The present invention relates to a sealed round window for a front-loading drum washing machine, which has a cup-like shape closed towards the inside of the washing machine and has a circular bottom and a side wall, wherein the bottom is formed by a substantially flat The inner surface and the sight glass of an edge region and the side wall of the cup which tapers towards the bottom are made of plastic. Background technique [0002] In the front-loading washing machine, the sealed round window is installed on the front, and the round window is mostly circular and has a sight glass made of a transparent material that functions as the sealed round window of the front-loading drum washing machine, so that the user can see inside the drum. With the sealed round window open, the laundry can be loaded directly into the drum and taken out again. Typically front loading front load washers use a cup-shaped sealed round window that closes towards the inside of...
