The present invention relates to a refrigerating built-in appliance configured for installation in a piece of kitchen furniture having a front panel hinged to a cabinet structure. The front panel is typically arranged frontally at a door of the refrigerating appliance and connected thereto by way of at least a sliding and connecting device which comprises a rail element and a sliding element.
In the above kind of appliances the sliding and connecting device is installed between the door of the appliance and the front panel of a piece of furniture containing the household appliance, such panel being a door of the furniture niche.
According to such known technique it is possible to use both hinges, i.e. the hinge of the built-in appliance door and the hinge of the furniture front panel, without the need of using expensive special hinges having several axis of rotation.
For practical and aesthetical reasons, the two “doors”, i.e. door of appliance and the panel/door of the piece of furniture, should remain as close to each other as possible during opening and closing, when there is a lateral shift between the two doors due to the two different vertical axis of hinges.
EP857929 discloses a built-in refrigerator in which a sliding element is installed on the vertical side of an appliance door, and a rail element is installed on a front panel of a piece of furniture configured to accommodate the built-in refrigerator, so that one of its ends protrudes from the sliding element during the entire rotation of the front panel which draws the appliance door. Therefore, for all possible positions of the front panel and door, both components of the sliding and connecting device are at least partially visible by the user when he/she opens the door of the appliance.
The same considerations apply to the solution shown in DE4200333A1 where a rail element is fastened to an upper side of an appliance door and a sliding element is fastened to a front panel of a piece of furniture configured to accommodate the built-in refrigerator.
Despite robustness and reliability of known sliding and connecting devices of the type above, they are generally perceived as cheap solutions due to their visibility to users when opening and closing the door of a refrigerator appliance.
Moreover, rail elements are typically provided with a removable plastic cover that conceals the screws used for fastening such element. During use of the appliance and in view of the position of the rail element near the vertical edges of the doors restrained to each other, such cover can be accidentally detached, increasing the low perceived quality of the device. The color of the material forming the rails may also fade over time further increasing the low perceived quality of the device.
For these reasons, direct connection of furniture panels to refrigerator doors is more and more used by manufactures of kitchen furniture. However, this solution is far more expensive and complex than sliding and connecting devices. Hence, a need exists to improve sliding and connecting devices for refrigerator built-in appliances.
To this end, this disclosure relates to a built-in appliance where at least one of the rail element and slide element is fully interposed between the front panel and the refrigerating appliance door so that it is hidden from view in the installed configuration.
According to a first aspect of the invention, the sliding element has a first flat portion configured to be fastened to a horizontal side of the refrigerating appliance door and a second portion configured to slide on the rail element fastened to the front panel. In this aspect the rail element is fully hidden by the appliance door in any positions thereof.
According to a further aspect of the invention, the first flat portion is configured to be fastened to a vertical side of the refrigerating appliance door and the second portion is configured to slide on the rail element fastened to the front panel.
According to a further aspect, the sliding element is L-shaped and one portion is fully interposed between the front panel and the refrigerating appliance door so that it is hidden from view.
According to a further aspect, the door of the refrigerating appliance presents a seat for the first flat portion of the sliding element so that said flat portion is substantially flush with the door.
According to a further aspect, both the sliding element and the rail element are fully interposed between the front panel and the refrigerating appliance door so that they are hidden from view in the installed configuration.
Further technical features and advantages of the invention will be clear in the following description, which is provided as a non-limiting example, with reference to the accompanying drawings.
