Abstract

A household appliance having at least one housing device having at least one housing part. The housing part includes at least one ventilation device having at least one ventilation opening. The ventilation opening includes at least one bulged-out wall portion and at least one bent-out wall portion. The bulged-out wall portion and the bent-out wall portion are configured and arranged relative to each other such that the view through the ventilation opening perpendicular to the housing part is substantially completely blocked.

First claim

What is claimed is:

1 . A household appliance comprising:
at least one housing device having at least one housing part, the housing part including a ventilation device having a ventilation opening, wherein the ventilation opening includes a bulged-out wall portion and a bent-out wall portion, the bulged-out wall portion and the bent-out wall portion being configured and arranged relative to each other such that a view through the ventilation opening perpendicular to the housing part is substantially completely blocked.

2 . The household appliance as recited in claim 1 , wherein an edge of the bulged-out wall portion bounding the ventilation opening and an edge of the bent-out wall portion bounding the ventilation opening lie at least one of substantially in one plane or at least partially overlap each other when viewed perpendicularly at the housing part.

3 . The household appliance as recited in claim 1 , wherein the ventilation device is formed in one piece with the housing part.

4 . The household appliance as recited in claim 1 , wherein the bulged-out wall portion and the bent-out wall portion point in opposite directions.

5 . The household appliance as recited in claim 4 , wherein in an installed condition of the housing part, the bulged-out wall portion points outwardly and the bent-out wall portion is directed toward an interior of the appliance.

6 . The household appliance as recited in claim 1 , wherein the bulged-out wall portion bounds the ventilation opening at a top thereof and the bent-out wall portion bounds the ventilation opening at a bottom thereof.

7 . The household appliance as recited in claim 1 , wherein the ventilation device is shaped like a gill.

8 . A method for producing at least one ventilation device on at least one housing part of at least one housing device of a household appliance, comprising the steps of:
initially creating a first formation in a first forming direction perpendicular to a plane of the housing part at predetermined position; dividing the first formation into at least two sections; and creating a second formation on at least one of the at least two sections in at least one second forming direction substantially opposite to the first forming direction.

9 . The method as recited in claim 8 , wherein the first formation is produced in the housing part by deep drawing.

10 . The method as recited in claim 8 , wherein a convexity is formed as the first formation, at least one of the longitudinal cross section or the transverse cross section of the convexity being at least one of substantially roundish or oval.

11 . The method as recited in claim 8 , wherein the dividing of the first formation into the at least two sections is accomplished by at least one of cutting, milling or lasering.

12 . The method as recited in claim 8 , wherein the at least two sections of the first formation are substantially equal in size.

13 . The method as recited in claim 8 , wherein the second formation on at least one of the two sections is formed by at least one of pressing or bending.

14 . The method as recited in claim 8 , wherein the housing part is coated after producing the at least one ventilation device.
