Description

MOUNTING ASSEMBLY FOR SECURING A DECORATIVE PANEL ONTO BUILT-IN HOUSEHOLD APPLIANCE AND MOUNTING METHOD

The present invention relates to a fully-integrated and a semi-integrated built-in household appliance, in particular a dishwasher, and specifically to a mounting assembly for securing a decorative panel on a front door of a built-in household appliance and a mounting method using the same.

It is customary to install a household appliance underneath a kitchen counter, between cabinets, and to integrate it with the kitchen furniture. A built-in household appliance is usually concealed with a decorative panel matching a design of the kitchen furniture and the dimensions of the household appliance. Household appliances, in particular dishwashers may have their control panels either on a front surface or on an upper edge of the front door. Consequently, depending on an arrangement of the control panel, the dishwasher may be either fully integrated or semi-integrated with the kitchen furniture as the customer must have access to the control panel. A customer generally purchases a built-in dishwasher and a matching decorative panel in an unassembled state. After delivery of the goods, the decorative panel must be fixed onto the front door at its place of installation by using a mounting assembly provided by the manufacturer.

Various mounting assemblies for fixing decorative panels to appliance doors are known. These mounting assemblies generally have a large number of components with complicated mechanical parts. Thus, in most cases an accurate and fast fixing of the decorative panel requires the involvement of a qualified technician performing the adjustment work.

EP 0 632 156 A1 discloses a conventionally used system for fixing a front panel to a door of a household appliance, in particular a dish washing machine for domestic use. The system disclosed therein, comprises a pair of cooperating coupling means for interconnecting a rear surface of the front panel and an outer surface of the door.

The aforementioned drawbacks of the known mounting assemblies are not exhaustive. The appliance door of a built-in dishwasher is generally constructed with several openings for receiving corresponding parts of the mounting assembly. Therefore, a noise level produced by the dishwasher during operation may be relatively high, if no additional measures are taken to prevent sound from leaking through these openings into the kitchen environment.

An objective of the present invention is to provide a mounting assembly for securing a decorative panel onto a front door of a built-in household appliance such as a dishwasher, and a method of mounting a decorative panel using the same which enables accurate and easy mounting of decorative panels, and overcomes the drawbacks of the aforementioned prior art.

This objective has been achieved by the mounting assembly and mounting method respectively defined in

claims

The mounting assembly according to the present invention comprises a coupling member for interconnecting a rear surface of the decorative panel and an outer surface of the front door. The coupling member further comprises an alignment portion integrally formed with the coupling member, for aligning and positioning the coupling member, relative the edges of the decorative panel, at a designated location on the rear surface of the decorative panel. Thereby, the customer is relieved from performing tedious measurement and adjustment tasks. Also, the use of any auxiliary means such as cardboard stencils, templates or the like becomes superfluous.

In a preferred embodiment, the alignment portion has been provided with alignment markings for facilitating alignment and positioning of the mounting assembly.

Household appliances may come in different dimensions and designs. Therefore, a decorative panel must have a size which specifically matches the dimensions and the design of the household appliance. Consequently, the designated location for installing the mounting assembly on the decorative panel may relatively shift with respect to the edges of the decorative panel depending on the specific dimensions and design of the appliance as well. Therefore, in another preferred embodiment, the alignment portion has been provided with a plurality of breaking grooves. The alignment portion can be shortened to a designated length matching the decorative panel by truncating the alignment portion at a respective breaking groove prescribed by the manufacturer.

In yet another preferred embodiment, the mounting assembly has a flat structure so that the mounting assembly can be sandwiched between a rear surface of the decorative panel and an outer surface of the front door. The mounting assembly of the present invention interconnects the decorative panel and the front door almost in a gapless fashion.

In a further preferred embodiment, the mounting assembly has been provided with a fixing means for fixing the coupling member flush on the rear surface of the decorative panel. In addition, the mounting assembly has been provided with a plurality of projections extending from a surface of the coupling member facing the front door, which are respectively insertable into a plurality of corresponding holes formed in the front door. The projections exactly fit into the holes. Thereby, the decorative panel can be secured on the front door while also acoustically sealing the holes.

In a still further preferred embodiment, the mounting assembly is provided together with a plurality of double sided adhesive tapes which can be arranged between the rear surface of the decorative panel and the outer surface of the front door to stick them together.

According to the mounting method of the present invention, the mounting assembly is initially aligned and positioned at a designated location on the decorative panel with reference to the edges of the decorative panel. Thereby, the projections on the mounting assembly exactly meet the holes on the appliance door. If necessary, the mounting assembly is shortened to a designated length as prescribed by the manufacturer matching the dimensions and the design of the household appliance. Prior to securing the decorative panel onto the appliance door, one or more double sided adhesive tapes may be placed between the front door and the decorative panel. Subsequently, the front door can be securely pivoted to a horizontal position for screwing the decorative panel from an inner side of the appliance door to tightly fasten the decorative panel against an outer surface of the appliance door. Therewith, the mounting of the decorative panel is finalized.
