Description

The present invention relates to the field of built-in domestic appliances, and in particular to a device for coupling an access door of a household appliance to an outer covering panel.
While reference is made hereinafter to a dishwashing machine, it is clear that the invention also applies to any other domestic appliance having an inner hinged door associated to an outer covering panel.
As it is known, so-called "fully integrated" domestic appliances, e.g. dishwashing machines, are installed and fully enclosed in kitchen furniture; the front door of the appliance is covered and completely hidden by a covering decorative panel having the same appearance as the surrounding furniture. The panel is applied to the appliance door and is mechanically connected to the door, so that the user, by opening the outer panel, also open the inner door.
Many coupling devices are known to connect the outer covering panel to the inner machine door.
For example, according to known kinds of coupling device, a bottom end of the panel is hinged directly to either the furniture or the machine structure, and a top portion of the panel is slidably connected to the machine door.
This kinds of solutions, however, are relatively complicated, and/or require a high number of component parts to be assembled, and/or are poorly flexible needing specifically designed parts of the machines.
Moreover, since the bottom end portion of the panel is supported by hinges that are directly fixed to either the machine structure or the furniture, the length of the decorative panel that can be applied is limited, while current design trend for furniture would require longer decorative panels.
It is an object of the present invention to provide a device for coupling an access door of a household appliance, in particular a dishwashing machine, to a covering panel and free from the aforementioned drawbacks.
According to the present invention, there is provided a device for coupling an access door of a household appliance, in particular a dishwashing machine, to a covering panel, the device comprising a top sliding coupling between the door and the panel and a bottom hinge connection for the panel; the device being characterized in that the hinge connection comprises at least one fulcrum adapter, having a seat engaged by a pin that is integrally carried by an inner surface of the panel facing the door; and connection members for fixing the adapter to a recessed bottom portion of the appliance in such a way the adapter projects frontally from the appliance and below and spaced apart from a bottom edge of the door.
A first advantage of the device according to the invention is the extreme structural simplicity, which makes the solution easy and cheap; a few components are required, and all components are easy and cheap to be manufactured and assembled. At the same time, the device of the invention is also fully effective and reliable in use.
Moreover, the device of the invention allows the covering panel to be easily and simply mounted on the inner door, without requiring any modification of either the machine structure or the furniture.
According to another aspect of the invention, it is also provided a mounting kit for coupling an access door of a household appliance, in particular a dishwashing machine, to a covering panel; the kit comprising at least one guide, to be fixed to an inner surface of the panel and engaged by a slide that slides along the guide and is hingedly connectable to the door; at least a support element provided with a pin and to be fixed to the inner surface of the panel; at least one fulcrum adapter, having a seat for housing the pin; and connection members for fixing the adapter to the appliance.
Also the kit as a whole is very simple and cheap to manufacture, and can be used with different appliances.
These and other advantages and features of the present invention will be clear from the following detailed description of an embodiment thereof, with reference to the attached drawings, in which:
