This has the advantage that the household appliance has an aesthetically pleasing, has handle-free front. Such a grip is by a one-piece plastic part formed, which on the side cheek between the outer door panel and the door inner shell is used. This solution However, it has the disadvantage that for household appliances different Size respectively a separate plastic part must be provided.

The Invention has therefore set itself the task of a door for a household appliance with a To provide grip insert, the most cost-effectively is. About that It is also an object of the invention to develop a concept of which for a series of different home appliances can be used to to be particularly cost-effective.

These Task is through a door solved with a built-in side bolster handle insert, wherein the handle insert in the longitudinal direction the side cheek is divided into at least two parts. This can a part identical for different devices to be used while the other part is exchanged, especially in different ones Lengths made becomes. This saves manufacturing costs. Especially preferred is the handle insert in the longitudinal direction the side cheek divided into three parts. This offers the advantage that different lengths variants be represented by one or more of the parts identical for different Devices used be while other parts are exchanged, especially in different lengths be used. Thereby can Parts of the handle insert for Doors different Height or width be used.

With a "sidewall" is one the four narrow sides of the door meant, which in each case between the outside or front side and the Inside of the door lie. The invention can be applied to both an upper or lower side cheek as well as on one or both of the lateral side cheeks.
