Description

Door handle for a household appliance door

The invention relates to a household appliance with a door handle according to the preamble of claim 1.

To open or close a door of a household appliance, this has a door handle that can be attached as a design element on the door front of the door and a plurality of plastic and / or metal elements may be composed.

From DE 20 2007 013 032 111 a generic household appliance is known, the appliance door has such a door handle. The door handle consists of a vertically arranged hollow cylindrical handle tube, which is inserted at its upper and lower end side between handle holders, which are mounted on the door. Depending on the design variant, the handle tube can be made of a metal or a plastic. In contrast, the upper and lower grip holder are mostly

Plastic injection molded parts, which are color-matched to the handle tube.

For a suitable color of the handle holder whose plastic starting material before a injection molding process, a matching dye can be added. In this case, however, the problem arises that

manufacturing technology due to the produced plastic injection molded part so-called

Flow lines or confluence lines or streaks remain visible, which are visually perceived as disadvantageous. Alternatively, the finished

Plastic injection molded part after the molding technically elaborate paint in the appropriate color.

The object of the invention is to provide a household appliance, in which the door handle can be produced easily manufactured.

The object is solved by the features of claim 1. advantageous

Further developments of the invention are disclosed in the subclaims. According to the invention a door handle is provided, which has a handle and at least one handle holder, which is connected to the appliance door. According to the

Characterizing part of claim 1, the handle holder

Decorative element, which covers the handle holder substantially visible. The matching color of the handle holder is thus not by coloring the starting material of the handle holder or by painting the

Handle holder, but rather by the designed as a separate component decorative element that can be mounted on the handle holder. The decorative element may also be made as a plastic injection molded component. In contrast to

Handle holder, however, the component geometry of the decorative element is designed much simpler than the complex grip holder geometry. Accordingly, the problem does not arise here that optically disadvantageous weld lines or flow lines remain visible in the decorative element. In addition, the sight protected arranged grip holder in a basic version, regardless of the color of the

Handle tube are kept and adapted only by appropriate selection of the decorative element with respect to color to the handle tube.

The household appliance according to the invention is used for household management and can be an example of a refrigerator, such as a refrigerator, a freezer, a freezer, a wine storage cabinet or a fridge freezer.

It is preferred if the decorative element are at least the front of the user readily visible pages of the handle holder are covered. That's how it works

Decorative element preferably in cross-section U-shaped profile or dome-shaped with a base wall and angled side walls to be formed, which limit an open insertion side, in which the grip holder is used. The U-profile-shaped decorative element can preferably be pushed releasably without tools on the handle holder, namely factory or user side. The hood-shaped decorative element can be placed in this case in a simple insertion movement from the outside on the handle holder.

In the assembly position, the decorative element can cover a front side facing outward wall of the handle holder, the upper top wall and / or the lower bottom wall of the handle holder visible. In addition, the grip holder one of Having externally accessible mounting side, on the example of a tool is attachable to mount the handle holder on the handle or to solve the two components from each other. The mounting side of the handle holder may be substantially visible from the outside, for example, facing the pivot axis of the door, so that the mounting side of the handle holder is not readily visible by the user. In such a construction, it is particularly preferred if the

Mounting side of the handle holder exposed from the decorative element remains. As a result, a simple tool access to the mounting side of the handle holder is ensured without the need to remove the decorative element for this purpose.

So that when opening and closing the door opened into the door handle

Actuating forces can be initiated without damage from the door handle in the appliance door, a component-rigid design of the handle holder is particularly preferred. In a technical realization of the handle holder may have a placed on the door front of the door, massive base body which protrudes forward in the Bautiefenrichtung from the front of the door. The main body can be extended in the Bautiefenrichtung backwards with a mounting leg, which is mounted on the narrow side edge of the door approximately via a screw connection. In this case, the decorative element can close with its free edges directly on the door panel of the door and surround the door outer edge tight.

Preferably, the decorative element has stop contours, which ensure a play-free mounting of the decorative element both in the device side direction, in the vertical direction and in the Bautiefenrichtung. Preferably, the decorative element for play-free fixation in the Bautiefenrichtung have an additional stop wall which engages around the back of the mounting leg. The stop wall forms together with the above-mentioned, located with the door panel in contact edge of the

Decorative element a position assurance in the Bautiefenrichtung. The position assurance in the high direction can be done by contrast, by the two angled side walls of the decorative element, in contact with the bottom and top walls of the

Handle holder are. In addition, a backup of the decorative element against unintentional detachment in the device side direction of advantage. For this purpose, the decorative element, in particular its base wall, on the inside have a latching element. When placing the decorative element on the grip holder, the locking element with a matching locking contour of the handle holder come into engagement. The latching contour may preferably be formed within a recess of the handle holder, which is set back by a lowering depth of the component surface of the handle holder. In the recess, a screw head of a fastening screw may be used with which the handle holder is bolted to the door. The detent contour provided in the recess may be an undercut which is in a side wall of the recess

is incorporated and can be engaged behind by the corresponding locking element of the decorative element. The protection of the decorative element against unintentional detachment is thus not by a non-positive clamping connection, but rather by a non-positive form-fitting connection, in which a detachment of the decorative element from the handle holder is permanently excluded.

Hereinafter, an embodiment of the invention with reference to the accompanying figures will be described.
