Description

Laundry treatment appliance

Field of the invention

The present invention generally relates to a laundry treatment appliance, especially a front loading washing machine, dryer or combined washer and dryer, both for domestic and professional use. More particularly, the present invention relates to a laundry treatment appliance comprising an operation element, a drawer and an opening configured for insertion/extraction of said drawer.

Background of the invention

Laundry treatment appliances/machines such as washers, dryers or combined washers and dryers, typically comprise a user interface, with an operation element, comprising a knob and / or a push button and / or a display and / or a further kind of device by which the user can modify and / or check the operation of the appliance; moreover, these laundry treatment appliances typically comprise a thin inlay with a hole for the operation element passage; such an inlay can comprise aesthetic symbols, which can, for instance, indicate the functions activated by the operation element on a predetermined angular position or can be transparent in order to show symbols and / or lights provided on the user interface.

The European patent application EP 2 436 828 A1 discloses a front panel with a user interface having a thin inlay placed around a knob, on one side with respect to the drawer, and on the other side with respect to the remaining user interface. This configuration has as a drawback several clearances between the drawer, the inlay and the user interface, resulting in a collection of dirt or dust in these spaces, which can affect the visual appearance of the frontal side of the laundry machine. Moreover, these spaces can lead to passages for contaminant entrance of particles into the clean chambers of the machine.

Summary of the invention

The object of the present invention is therefore to provide a laundry treatment appliance that avoids the collection of dirt or contaminating particles at the front panel and/or in the appliance. It is a further object of the present invention to provide a laundry appliance easier to assemble with a good appearance independent of the number of assembled components.

According to a first aspect, the invention relates to a laundry treatment machine, comprising an operation element, a drawer and an opening configured for insertion/extraction of the drawer, wherein the drawer comprises a drawer frontal panel that comprises a shaped portion which in a fully inserted position of the drawer at least partially encircles the operation element.

Preferred embodiments of the invention are described in relation to the dependent claims and the description of the enclosed drawings.

The invention is based on the consideration that a collection on and an entrance into the region of the drawer frontal panel of dirt or other contaminating particles should be avoided for several reasons. Firstly, the visual appearance of the appliance is diminished by dirt collection on the appliance and/or its front panel, since this front panel is the optical focus for a user, and its minor appearance can lead the user to infer a low quality of the whole machine. These dirty / contaminant particles can also enter the interior of the machine and get into the compartments of the drawer and/or the washing tub, leading to a possibly reduced washing efficiency and / or to a damaging of delicate / sensitive components, such as electronic boards, etc.

Applicant has recognized that a most critical spatial region is located around the operating element which should be covered in order to prevent dirt to collect / enter the machine. This should be achieved without separate elements which would degrade the visual appearance of the laundry treatment appliance.

Applicant has found that by providing the drawer frontal panel with a portion which encircles at least partially the operating element, a high-quality appearance of the frontal panel can be preserved while simultaneously solving the above described problem and essentially sealing a gap around the operating element. The terms laundry treatment appliance or laundry machine or laundry treatment device includes washing machines as such but also combined washing/drying machines that can incorporate both functionalities. Also the terms laundry washing machine and washing machine are used interchangeably. The laundry washing machine can, for instance, be designed as a front-loading laundry washing machine. Alternatively, the appliance can be a dryer.

In a preferred embodiment, the laundry treatment appliance comprises a machine front panel, whereby the operation element and / or the opening are provided on this machine front panel.

The operation element is any kind of device which serves for receiving user interaction actively and/or for displaying status information of the laundry machine. This means the user can, by utilizing the operation element, control the machine and/or obtain information of its state, especially by at least one optical indicator. The operation element preferably comprises a knob and / or a push button and / or a display and / or light. The operation element can thus be built as knob and/or a push button and / or a display or a light. For instance, it can be built in a combined design as a rotatable knob which can be pushed to act as a push button. The knob can comprise a display which shows, for instance, the currently selected treatment program and/or parameters and / or status updated thereof and / or errors which occurred. Additionally or alternatively, the display can be of the touch-type, allowing the change of programs or display modes through the user touch of said display.

The operation element preferably comprises a circular shape at least partially, whereby the drawer comprises a drawer frontal panel that comprises a rounded profile which in a fully inserted position of the drawer at least partially encircles the circular shape.

The operation element advantageously has an essentially circular perimeter concentric around a vertical axis, whereby the shaped portion of the drawer frontal panel extends in a lateral direction parallel to the vertical axis. The fully inserted position of the drawer preferably corresponds to its position during operation of the laundry treatment appliance. In case of a washing machine, the drawer preferably comprises at least one compartment for a washing and/or rinsing product which can be transported by a water stream into the washing tub. The fully inserted position is preferably defined and mechanically realized by block or stop means which limit the movement of the drawer further into an opening which receives it. These stop means can, for instance, be realized by the opening having a smaller cross section than the drawer frontal panel and / or by any known locking device configured such that the drawer is stopped in its movement when it is entirely inserted into the opening.

For at least partially encirclement of the operation element by the shaped portion of the drawer frontal panel it is meant that said shaped portion at least partially follows the contour of the operation element and / or the eventual aesthetic element framing said operation element in a congruent way; in case of at least partly circular operation element such as a knob, the shaped portion is also shaped in a circular way, following / surrounding / wrapping the operation element on the fully inserted position of the drawer; in case of non-circular operation elements, the shaped portion, following the contour of the operation element, have a consequent non-circular portion.

In a preferred embodiment a recess is provided in association with the drawer opening, this recess having a depth dimensioned such that in a fully inserted position, the drawer frontal panel flushes with the external surface of the appliance and / or the machine front panel. Consequently, being the drawer frontal panel justified with the appliance / front panel, the visual appearance of the laundry treatment appliance is improved.

Preferably an aesthetic ring is provided on the appliance and / or on the machine front panel which frames the operation element, whereby the shaped portion of the drawer frontal panel in a fully inserted position wraps the ring at least partially. The aesthetic ring is preferably made of plastic. It can preferably comprise printed symbols or patterns which support an aesthetically pleasing appearance of the laundry treatment appliance. A further decoration element is advantageously provided on the shaped portion of the drawer frontal panel which can further improve the aesthetic appearance of the appliance.

The decoration element is preferably assembled to the shaped portion by a snap connection and/or by welding and/or by gluing.

In a preferred embodiment an inlay is provided on the drawer frontal panel. The inlay can provide information on available laundry treatment programs and/or contain decorative elements or symbols. Preferable, the inlay is transparent, whereas the general information to the user are provided below said inlay. The contour of the inlay is preferably congruent to the contour of the drawer frontal panel.

The inlay is preferably assembled to the drawer frontal panel by a snap connection and/or by welding and/or by gluing and/or by an adhesive tape.

Advantageously, the drawer frontal panel comprises a recess on which the inlay is assembled, the depth of the recess being dimensioned to allow the flush of the inlay with the external surface of the drawer frontal panel and / or the machine front panel when the drawer is on its fully inserted position on the appliance and / or on the front panel. In other words, the inlay is justified with the external surface of the drawer frontal panel and / or the appliance/machine and / or the front panel.

The drawer frontal panel preferably comprises a further shaped portion which substantially encircles at least partially at least a shaped portion of the appliance door adjacent to the drawer frontal panel.

The drawer frontal panel advantageously comprises a handle with a frontal recess or a frontal recess configured to allow the insertion of a user's finger. By inserting a finger, the user can easily pull the drawer and extract it at least partially so he/she can gain access to the compartments of the drawer and fill the respective compartment with a washing and/or rinsing product. The recess is preferably placed adjacent and below the inlay which leads to an intuitive and convenient operation/handling of the drawer.

The laundry treatment machine is preferably a front-loading washing machine, a dryer or a front-loading combined washer/dryer.

The advantages of the invention are essentially as follows. By providing a drawer frontal panel which in its shape encircles at least partially an operation element of the appliance, the collection of dirt and entry of dirt into the interior of the appliance are prevented, preserving simultaneously the aesthetic appearance of the part of the appliance with which the user interacts for its operation and the washing quality of the cleaning process.
