Definitions

• the invention relates to a large household appliance with a housing enclosing a treatment room and with a movable door by a handle, the front panel having a control panel and an outer door.
• the design of the door of a large household appliance takes place increasingly aesthetically.
• the design of a large household appliance is essentially determined by its outer door. Their design can already be predetermined by a respective manufacturer in a neutral form.
• the outer door can also be designed in such a way that it allows the insertion of a decorative trim in the outer door.
• Doors of such large household appliances also have a control panel, which is arranged in the upper portion of the door and which includes the controls.
• the controls can be arranged on the front side on the front of the control panel or on the front side of the control panel and thus the door.
• the control panel is usually connected via a detachable connection with the door, more precisely a part of the door not visible from the outside.

• the door is often opened by means of a bow-type handle placed in the region of the outer door, e.g. in the form of a U-shaped bent metal rod.
• the handle should be as high as possible, i. in the immediate vicinity of the control panel of the door, be arranged. Since the outer door is a supporting element of the door of the large household appliance, the attachment of the handle can be made directly to the outer door itself.
• the outer door consists of a glass plate.

• This causes the forces acting on the handle are kept away from the soffits of the glass openings and act exclusively on the bearing plate.
• the ends of the handle can be bolted directly to the metal plate.
• DE 36 44 021 AI describes a door having at least one receiving pin on which a handle can be plugged.
• Handle and spigot are at the front of the household appliance by a fastener, such as a screw, releasably connected to each other.
• a Griffblende Before attaching the handle with the spigot a Griffblende can be attached to selbige, which is held by the handle.
• the arrangement described in this document is directed in particular to oven doors.
• the doors of appliances of this type differ from those of dishwashers in that not the entire front of the household appliance is formed by a pivotable door.
• the part carrying the controls is rather an integral part of the housing and immovable.
• the door itself occupies only part of the front of the large household appliance. The described arrangements are therefore not directly transferable to large household appliances, in which the entire front side is formed by a door.

• the handle is arranged on the control panel and frictionally connected to a holding device of the door arranged on the rear side of the control panel.
• the degrees of freedom in the design of the outer door are larger. Due to the frictional connection of the handle with the holding device of the door arranged on the rear side of the control panel, it is ensured that no or at least no large forces are exerted on the relatively unstable control panel, which usually consists of a plastic or stainless steel.
• the holding device is formed by an inner door of the door or formed by a support bracket holding the operating elements, which is arranged between the control panel and an inner door of the door.

• Figure 1 shows the arrangement according to the invention of a bow-shaped handle 1 in the region of the control panel for opening the door 2. Due to two on the underside of the door hinges connected to the housing, it is advantageous for a comfortable opening, the handle as far as possible in the upper area to arrange the door. So far, it was only possible to arrange the handle 1 in the vicinity of the control panel 3 on the outer door 4. This was unavoidable because the control panel 3 is not a supporting element of the door 2, but is connected for example via a latching connection with a back of the control panel 3 existing part of the door 2. A removable without tools connection between control panel and door is due to the embedded in the control panel controls to advantage this to wait or to exchange.
• the stable attachment of the handle in the control panel therefore requires constructive measures to ensure the tightness of the handle on the door and to prevent damage to the control panel.
• a possibility of attaching the handle to the door in the region of the control panel is shown in a first variant.
• the control panel 3 is connected via a detachable connection, e.g. a locking connection, connected to a support plate or an inner door of the door of the large household appliance to make it easy to solve any time possible.
• the control panel 3 is therefore unable to fully absorb the forces exerted during the operation of the handle, without detaching from the inner door or the support plate or being damaged.
• the construction according to the invention therefore has the structure that a frictional connection between the handle 1 is not made to the control panel 3, but to a holding device 11.

In this way, a frictional connection of the handle 1 via the bolt 22, the fastening device 9 and the bayonet lock 13 on the holding device 11 is ensured. The forces acting on the handle are thus effectively kept away from the control panel 3.
