Definitions
- the present invention generally relates to laundry treatment devices, such as front loading washing machines, washers/dryers, dryers, both for domestic and professional use. More particularly, the present invention relates to a laundry treatment device including a control-panel assembly.
- laundry treatment devices include a casing defining a front wall. Front walls made as a single integral piece, without any visible seam, so as to appear as a continuous uniform external surface, are increasingly popular and appreciated by the users.
- an aperture for the loading/unloading of the appliance is generally formed, which can be preferably opened/closed by a suitable door, as well as an additional aperture, to which a control panel is associated.
- control panel of an laundry treatment device typically is connected to an inner printed circuit board (or PCB) that is electrically connected to electronic components and control members, as well as a power supply, associated therewith for implementing corresponding control functionalities, e.g. powering, driving, activation, deactivation of operative loads including electric, electronic, electro-mechanical and/or electro-hydraulic parts of the appliance (such as motor, solenoid valve, further PCBs and the like).
- PCB printed circuit board
- the control panel is operated by the user by means of an outer dashboard, which also represents the external visible surface of the assembly, positioned at the front wall.
- an outer dashboard which also represents the external visible surface of the assembly, positioned at the front wall.
- displays, knobs, touch screens and/or any other input devices are formed in order to control the operative status of the appliance and/or for example select the appropriate programs or cycles and the parameters thereof.
- the outer dashboard is coupled to the front wall, at the aperture therein, and the PCB is located within the casing. Different couplings between the outer dashboard and the front wall are possible.
- a laundry treating apparatus which can be manufactured easily.
- the laundry treating apparatus includes a cabinet, a drum rotatably disposed in the cabinet configured to hold laundry therein, a front cover including a door aperture to load the laundry in the drum, and at least one panel aperture configured to receive a control panel therein.
- the control panel is mounted on the front cover by means of a mounting plate which is detachably coupled to flange parts.
- Applicant has considered the layout of the panel control assembly described in EP 2140058 .
- the appliance herein disclosed includes a full front wall, in which two apertures are provided, one for connecting the panel assembly and one for connecting the drawer.
- the full front wall of the device disclosed in the mentioned EP patent is made of metallic material.
- the panel aperture and the drawer aperture are separated by a crosspiece, which is also made of in metallic material.
- the control panel is coupled to the casing of the device from the back, e.g. the panel assembly is connected to the front wall from the interior of the casing, and therefore no portion of the panel assembly is overlapping a portion of the front surface of the front wall.
- the visible and accessible parts of the crosspiece made of metal are also not covered by any additional element, and thus its edges, which are possibly sharp, can cause damage to the user who accidentally touches the same while operating the control panel.
- the invention relates to a laundry treatment device comprising:
- the laundry treatment device is a washing machine or a dryer or a washer/drier.
- the laundry treatment device includes a casing delimiting the appliance, wherein a laundry treatment chamber is housed, and a front wall of the same.
- the front wall of the casing has a front surface which is a continuous surface having an aperture which is called panel aperture.
- an inner volume is defined by the assembly casing and front wall. Element facing said inner volume are called elements which are “inward facing” elements, while elements not facing this inner volume are called “outward facing” elements.
- the front surface of the front wall represents the external front surface of the appliance, thus facing the outside to the casing, and it is advantageously construed as a single continuous surface holed by the panel aperture.
- These front walls are in jargon also called "full front".
- the front wall can also include additional element(s) separated from the portion of the front wall defining the continuous front surface.
- the front wall could include a first portion having a panel aperture to host the control-panel assembly which is positioned in the top-most part of the front wall, and a second portion, separated from the first, which covers the lowermost part of the front wall.
- top top
- bottom bottom or “upper” and “lower” are herein used with reference to the standard standing configuration of the laundry treatment device when in use.
- the control panel assembly is manually operated by a user in order to select the programs or to input any data relative to the functioning of the appliance.
- the control panel assembly can also display warning messages or instruction for maintenance coming directly from the laundry treatment device.
- the front wall in the portion defining the continuous front surface, includes further apertures.
- the front surface includes an opening for the access into the appliance, e.g. in a washing machine or dryer the opening is used to load and/or unload the laundry.
- the laundry treatment device includes a drawer.
- the drawer includes, in case of a washing machine, a detergent dispenser, e.g. the detergent is inserted within the drawer and, during the washing cycle, it is flushed within the drum by flushing water.
- the drawer is a water drawer where, in case of a dryer, the condense water is collected during the drying cycles.
- the drawer is connected in a retractable manner onto the front wall of the laundry treatment device, at the drawer aperture, so that a user can open and close the same in order for example to introduce the detergents and/or to remove the condense water.
- a seat is provided, in order to house the drawer and allow the opening and closing movements.
- Drawer seat and the dashboard are coupled to two different apertures provided on the front wall, the panel aperture and the drawer aperture, and a crosspiece is interposed therebetween.
- the crosspiece interposed between the two apertures helps to stabilize the front wall, creating a supporting element for the wall, and it also helps to obtain a correct alignment of the control panel assembly and the drawer seat on the front wall during the assembly of the laundry treatment device.
- both the drawer seat and the dashboard are fixed to the crosspiece separating the two apertures one from the other.
- the alignment of both drawer seat and dashboard is greatly simplified. This in turn reduces the manufacturing required time and costs.
- the final aesthetical appearance of the laundry treatment device is improved.
- first and a second mechanical coupling system (not necessarily two distinct systems, but possibly also two totally or partially coincident systems) which are at least partially included in the crosspiece itself.
- the first and second coupling system may be a same system (i.e. they may coincide).
- they may comprise screw holes provided in the crosspiece and corresponding screws for fixing the dashboard and/or the drawer seat to the crosspiece.
- first and/or second mechanical coupling system may advantageously comprise hooks formed in the crosspiece to hook corresponding elements in the dashboard and/or drawer seat.
- first and a second mechanical coupling system may comprise a snap fit comprising, for example, a clip provided on the dashboard/drawer seat which is configured to snap on a flat portion of the lateral edges of the crosspiece (which flat portion in this case is comprised in the mechanical coupling system).
- all visible portion of said continuous front surface is seamless.
- the visible portion of the front wall is a single piece, for example a single metal sheet which has been properly shaped. The sheet has not been welded or otherwise connected.
- the visible portion of the front wall means that portion which, when the laundry treatment device is in an assembled configuration, is visible by the user from the outside of the casing. This portion is preferably the seamless one, because it gives a better aesthetical appearance to the laundry treatment device and in addition it avoids any possibility of injuries caused by sharp edges which can occurs when seams in metal material are created (for example when the seam is unfinished by mistake).
- Other portions of the front wall which are covered by additional elements or which are hidden by other casing's parts can include seams.
- said drawer seat is integral to said outer dashboard forming an outer dashboard assembly.
- the seat is an integral part of the dashboard.
- seat and dashboard form a single integral element.
- said first mechanical coupling system and second mechanical coupling system are a single coupling system.
- outer dashboard and drawer seat are a single element, i.e. the outer dashboard assembly
- a single coupling of a single element onto the crosspiece is enough to obtain all the advantages listed above.
- the first mechanical coupling system thus coincides with the second mechanical coupling system.
- a single mechanical coupling system can advantageously be present, which can embrace both drawer seat and dashboard and fix both onto the crosspiece.
- the outer dashboard or an outer dashboard assembly formed by the drawer seat and the outer dashboard, when coupled to said panel aperture and in an assembled configuration, is completely surrounded by said front wall.
- the outer dashboard or outer dashboard assembly i.e., including the drawer seat
- the outer dashboard/dashboard assembly is, in an assembled configuration, in contact to the front wall in all directions.
- there is no direct contact but an aperture or another body is interposed between a side of the dashboard/dashboard assembly and the front wall.
- the dashboard/dashboard assembly is still encircled by a portion of front wall, regardless of whether the front wall is in contact or not to the dashboard/dashboard assembly.
- the dashboard can include a portion external to the casing which covers the front wall to such an extension that it comes into contact to lateral wall(s) of the casing.
- the dashboard also inserted into the panel aperture, there is always a portion of dashboard/dashboard assembly which is completely surrounded from all directions by the front wall.
- dashboard/dashboard assembly is advantageously built-in (or embedded) in the front wall.
- said drawer aperture and/or said panel aperture has an edge defining a closed curve.
- the panel and/or drawer aperture includes an edge which is a closed curve, which means that the aperture is completely contained in the front wall.
- the shape of the aperture and/or of the edge of the aperture is not relevant in the present case and it can be oval, rectangular, etc.
- said crosspiece defines a crosspiece front surface, said crosspiece front surface being a portion of said continuous front surface of said front wall.
- the crosspiece is not an added element to the front wall, but it is an integral part of the same, and the front surface, which also includes the crosspiece front surface, is globally continuous. More preferably, the whole front surface is also seamless.
- the crosspiece can be attached to, for example by welding, the front wall, so it is a separated element that has to be assembled during the laundry treatment device production.
- Other means to fix the crosspiece are included as well, for example by screws, glue, snap-fit elements, etc.
- said outer dashboard and/or drawer seat includes a rear surface, a portion of said rear surface being in abutment against said crosspiece front surface when said laundry treatment device is in an assembled configuration.
- the crosspiece is substantially covered (or overlapped) by the dashboard and/or drawer seat and thus it is not directly reachable by the user when the laundry treatment device is assembled.
- the crosspiece therefore is not required to have a proper finishing, such as smooth and rounded edges in order not to injure the user.
- a not covered crosspiece with sharp edges can cut the user's fingers when he/she is operating the dashboard to input some information on the same.
- said first and/or second mechanical coupling includes a screw, screw threads on said outer dashboard and/or drawer seat and a hole on said crosspiece.
- a screw coupling is particularly effective in case of vibrations, such as those present in a laundry treatment device during washing and/or rinsing cycles, and remains fastened.
- said drawer seat is coupled to an edge of said drawer aperture by means of a drawer seat mechanical coupling.
- said drawer seat mechanical coupling includes a screw coupling element.
- the drawer seat is also coupled to the drawer aperture.
- a vertical section of said front wall presents a concavity pointed towards the internal of said casing.
- the shape of the front wall is not flat, but substantially curved.
- the curvature is along a vertical plane, according to a favorite embodiment, so that the front wall has a rounded appearance which is particularly pleasant and appreciated by the user.
- the dashboard of the invention fits easily due to the fact that preferably the outer surface of the dashboard substantially represents a geometrical continuation of the front surface of the front wall without protruding from the same, i.e. it is flush to the front wall surface.
- said outer dashboard is made of a plastic material and said front wall is made of a metallic material.
- the front wall of full front laundry treatment devices is made of metal.
- the full front shape is relatively easily retrievable by suitably bending a sheet of metallic material, such as steel.
- the dashboard is made of plastic material, because the coupling between plastic and metal is more reliable and easy to be manufactured than a metal to metal connection.
- said crosspiece is a separated element fixed or fixable to said front wall to separate said panel aperture and said drawing aperture.
- Figure 1 schematically shows a perspective view of a laundry treatment device 100 according to the present invention.
- the teaching of the present invention may be applied to substantially any appliance for laundry treatment, e.g. to washer/dryers, washing machines (as exemplary illustrated in the figures and to which reference will be made in the following by way of a non-limiting example only), dryers, etc.
- the device 100 comprises a substantially parallelepiped-shaped casing 2, which encloses an inner compartment comprising a laundry treatment chamber, for example a rotating drum 12 for housing the laundry to be treated and a tub encasing the drum (tub is not visible in the appended drawings). Moreover, the device includes an access door 3 provided on a front wall 4 of the casing for accessing the laundry treatment chamber 12 thereby allowing loading/unloading of the laundry by a user. The front wall 4 is connected to an open side of casing 2.
- the casing 2 preferably also includes a bottom wall or basement 5, a top wall 6, a back wall 7, and two opposite lateral walls 8, 9.
- lateral walls, front walls, top wall and basement are separated pieces which are then assembled together via suitable fastening means.
- some of these walls can be a single piece, for example lateral walls and back wall can be a single U-shaped piece.
- casing 2 may include a single wall, or two walls, such as the back and/or one of the side walls.
- casing and front wall together defines a substantially close volume, regardless of the relative extension of front wall and the rest of the casing.
- Walls are preferably made of metal, however also plastic is possible. Also, in a non-depicted embodiment, some of the walls can be made of a material, and some other(s) can be made of a different material.
- a horizontal plane is defined (plane (XY) in Figure 1 and 3 ), which is generally the plane on which the bottom wall or basement 5 lies and generally it is also parallel to the top wall 6 of the casing in a mounted configuration.
- the appliance also extends along a vertical direction denoted with Z.
- the front wall 4 includes an external continuous surface 4a having a plurality of apertures, as better detailed below.
- the front external surface is the external front surface of the appliance.
- Front wall 4 is preferably made of a metallic material, for example in stainless steel.
- the front surface 4a is preferably continuous and even more preferably seamless, at least in the visible portion(s) of the same.
- Continuous surface means that the surface is formed as a single member.
- Sealess means that, in addition to be continuous, there are no seams which indicate that for example welding has been used to join together different parts.
- portions of the front wall 4 can be present. The absence of seams improves the overall appearance of the laundry treatment device 100.
- the front wall 4 preferably includes four rounded corners 4b, 4c, 4d, 4e along its outer edge.
- "Rounded corner” means a corner which does not include sharp and abrupt changes in directions of the surfaces forming the same; on the contrary in a rounded corner the surfaces merges smoothly and with continuity. The round corners give a more aesthetically pleasant look to the device 100.
- the front wall 4 can be obtained by a single sheet of metal.
- it can be obtained by a sheet of stainless steel.
- the front wall can be coated by suitable coating to prevent corrosion.
- the front wall can be colored of any color and gloss.
- the front wall 4 defines a top portion 4a', a middle portion 4a"' and a bottom portion 4a", the terms “top”, “middle” and “bottom” used with reference to the standard standing configuration of the household appliance when in use.
- top portion 4a' and the middle portion 4a"' of the front wall 4 are a single (or one-piece) element, i.e., having a continuous and/or seamless front surface 4a, while the bottom portion 4a" can be permanently fixed to it, for example welded to it, or it can even be added as an additional element which can be disassembled from the rest of the front wall.
- the front wall 4 includes an outer edge which can be divided in a top edge 50a, which is the portion of the outer edge comprised between corners 4b and 4c, a bottom edge 50b, which is the portion of the edge located between corners 4d and 4e, and two lateral opposite edges, 50c and 50d, which are the portions of outer edge present between corners 4b and 4e, and 4c and 4d, respectively.
- Front surface 4a includes a laundry opening 3a for the access into the laundry treatment device 100, in particular to the laundry treatment chamber 12 so that laundry can be loaded or unloaded to/from the laundry treatment device 100.

- the door 3 is coupled to a recessed portion 3b of the front wall 4a: in this embodiment, the front wall 4 includes the recessed portion (see figures 3 and 4 ) in the center of which the door opening 3a is formed.
- the dimensions of the opening 3a are such to be suitable to accommodate the door 3.
- the door 3 is then rotatably coupled to the door opening 3a and, when mounted and in a closed position, it preferably does not project substantially beyond the front surface 4a due to the recess presence. In other words, an outer surface of door 3 matches the front surface 4a of front wall 4.
- the door 3 and the recessed portion 3b are located in the middle portion 4a"' of the front wall 4.
- the front wall 4 is not flat, i.e., it does not lie completely on a single plane. On the contrary, it preferably includes a concavity pointing towards the inside of the casing 2, being convex on the outside.
- the front wall 4 - in a section along plane parallel to plane (Z, Y) - has substantially a smoothed trapezoidal shape, the top 4a', the bottom 4a" and the middle portion 4a"' lying on three different planes which form an angle one with respect to the other(s) and also with the vertical direction Z defined by the casing 2, forming in this way the inward concavity.
- the three planes are preferably connected smoothly and without sharp corners, as clearly visible in figure 5 .
- the front wall 4 can include a substantially constant curvature, the concavity still oriented towards the inside of the casing 2.
- the front wall could be a portion of a cylindrical mantel.

- upper wall and bottom wall are continuous with the front wall.
- corners 4b, 4c, 4d, 4e formed where side walls and upper/bottom walls merge into the front wall are seamless, because they are not formed by joining different elements, but they are formed during a single process of forming of the front wall, for example by pressing a single metallic sheet.
- the two side walls 8a, 9a extend from the side edges 50c and 50d of the front wall 4 substantially perpendicularly to the front wall 4 towards the lateral walls 8 and 9 respectively, or the casing 2, so as to be aligned to these lateral walls.

- the casing flange 29a, 29b, 29c are located at lateral walls 8, 9 and bottom wall (or basement) 5.
- Flanges can be formed continuously with the wall from which they extend, or they can be welded to the same. In a different embodiment, only some of the flanges are formed continuously while others are fixed to the front wall 4. Flanges 19a, 19b, 19c, 29a, 29b, 29c are not visible from the outside of the device 100 when the front wall 4 is assembled to the rest of the casing 2, being hidden inside the casing 2 in an assembled configuration itself.

- the second mechanical element 30 includes screw threads 31 provided in the rear surface 11r of the dashboard 11, a hole 32 provided in the flange 16 formed around the panel aperture 15, and a screw 33 which is inserted in said hole and screwed in said threads to tighten a coupling of a second type with respect to the snap-on coupling provided by tongues 22.
- the outer dashboard 11 is preferably fastened to the crosspiece 66 via a first mechanical coupling system 67.
- the crosspiece 66 itself comprises at least an element, part or portion of such first mechanical coupling system.
- the crosspiece includes a hole 64 of the first mechanical coupling system 67, on which a screw 69 is inserted and fastened into a screw thread 68 provided on the rear surface 11a of the outer dashboard 11. More preferably, two holes 64, one on top of the other in the vertical direction Z are provided also on the crosspiece 66, on which two screws are inserted, which are then screwed into two screw threads formed on the rear surface 11r of the outer dashboard.
- the dashboard 11 When the dashboard 11 is coupled to the front wall at the panel aperture 15, there is at least a portion of the dashboard 11 which is completely surrounded by the front wall.
- the front wall 4 embraces at least a portion of the dashboard which, in all possible directions, is embraced by the front wall.
- the dashboard 11 includes, extending from its rear surface 11r, a flange or ridge 19 which is inserted in the aperture.

- a wider aperture is present to house both control panel and drawer.
- the dashboard is still surrounded in all directions by the front wall, because beyond the portion of aperture, along a horizontal axis for example, a piece on front wall is still present, the piece of front wall which forms the edge of the "wider" aperture.
- the external portion of the dashboard extend along the front surface and can cover the front wall 4 up to the casing 2 in one or more some directions.
- the external portion of the dashboard 11ext can reach one (or more) of the casing lateral walls 8 or 9, or the casing's top wall 6, if it extends along a horizontal, or vertical, direction, thus without leaving portions of the front wall between the dashboard and the casing visible in that direction.
- the dashboard is still completely surrounded by the front wall also in this embodiment, due to the fact that the flange 19 is still inserted in aperture 15 and thus edge 15a completely surrounds the flange 19.
- the external portion 11ext of the dashboard 11 is flush-mounted on the front wall 4, being flush with the front surface 4a.
- the aesthetical appearance of the assembled dashboard 11 on the front wall 4 is that of a substantially continuous surface where the external portion 11ext matches the external surface 4a of front wall 4.
- Laundry treatment device 100 also includes a detergent drawer 63.
- Detergent drawer 63 is retractably mounted to said front wall 4 so that it can be opened and closed.
- the detergent drawer is generally used to introduce detergents or other products in order to perform a proper washing cycle.
- Detergent drawer includes a detergent drawer front wall 63a, which also remains external to the casing 2 when the laundry treatment device is in an assembled configuration, and it is so shaped to be easily gripped by the user in order to open and/or close the drawer 63.
- Drawer 63 is coupled to drawer aperture 60 of front wall 4.
- a drawer seat 61 is provided, whose dimensions are optimal to house the drawer 63 in a slidable manner.
- the drawer seat 61 is thus fixed to the front wall 4 at the drawer aperture 60.
- Drawer seat 61 is preferably made of plastic material.
- Drawer seat 61 after being mounted on the drawer aperture 60, is then covered by the drawer front wall 63a so that drawer seat becomes substantially invisible when the laundry treatment device 100 is in an assembled configuration.
- Drawer front wall 63a thus is positioned in front of the drawer aperture 60 closing the same.
- the front wall 63a of the drawer is mounted on the drawer seat so that it is substantially flush-mounted to the front wall, i.e., the front surface 4a of the front wall is substantially flush with a front surface of the drawer front wall 63a.
- a single "larger" aperture is provided, as mentioned previously, to house both the control panel assembly 1 and, adjacent to the latter, the detergent drawer 63 (so the crosspiece is not present).
- Drawer seat 61 is inserted into drawer aperture 60 and then fixed to the same.
- a mechanical coupling 65 is used.
- Mechanical coupling 65 includes for example a screw 65a inserted into a hole 65b provided in proximity of the edge 60a of the drawer aperture 60. The screw 65a is thus screwed into a screw thread (not shown) of the drawer seat 61. Any other mechanical coupling can be used as well, in order to firmly fasten the drawer seat to the drawer aperture 60, preferably in proximity of the drawer aperture edge 60a.
- the drawer seat 61 is also preferably fastened to the crosspiece 66 via a second mechanical coupling system 67.
- the crosspiece 66 itself comprises at least an element of such second mechanical system.
- the crosspiece 66 includes a hole 64 of the second mechanical coupling system, on which a screw 69 is inserted and fastened into a screw thread 68 provided in the rear surface 11a of the drawer seat 61. More preferably, two holes 64, one on top of the other in the vertical direction Z are present at crosspiece 66, on which two screws are inserted, which are then screwed into two screw threads.
- drawer seat 61 and the external portion 11ext of the outer dashboard 11 form an integral piece, forming an outer dashboard assembly. Therefore, first and second mechanical systems 67 are a single system, because fastening of one of the dashboard and drawer seat to the crosspiece automatically means fastening the other of the drawer seat and dashboard to the crosspiece.
- first and second mechanical coupling systems can be different one from the other, for example one of them might include a snap-fit system and the other one a screw coupling system.
- the crosspiece includes a part of both the first and second mechanical coupling system.
- the external portion 11ext of the dashboard 11 and drawer seat 61 are molded together and are made of plastic material.
- a connecting element joins together the dashboard external portion 11ext and the drawer seat 61.

Description
- The present invention generally relates to laundry treatment devices, such as front loading washing machines, washers/dryers, dryers, both for domestic and professional use. More particularly, the present invention relates to a laundry treatment device including a control-panel assembly.
- It is known that the aesthetical appearance of laundry treatment devices is important and represents a characteristic that might determine the appliance's choice by the user. Generally, laundry treatment devices include a casing defining a front wall. Front walls made as a single integral piece, without any visible seam, so as to appear as a continuous uniform external surface, are increasingly popular and appreciated by the users.
- In these front walls, also called "full front", an aperture for the loading/unloading of the appliance is generally formed, which can be preferably opened/closed by a suitable door, as well as an additional aperture, to which a control panel is associated.
- As known, the control panel of an laundry treatment device typically is connected to an inner printed circuit board (or PCB) that is electrically connected to electronic components and control members, as well as a power supply, associated therewith for implementing corresponding control functionalities, e.g. powering, driving, activation, deactivation of operative loads including electric, electronic, electro-mechanical and/or electro-hydraulic parts of the appliance (such as motor, solenoid valve, further PCBs and the like).
- The control panel is operated by the user by means of an outer dashboard, which also represents the external visible surface of the assembly, positioned at the front wall. On the dashboard, displays, knobs, touch screens and/or any other input devices are formed in order to control the operative status of the appliance and/or for example select the appropriate programs or cycles and the parameters thereof.
- The outer dashboard is coupled to the front wall, at the aperture therein, and the PCB is located within the casing. Different couplings between the outer dashboard and the front wall are possible.
- In
EP 2140058 , a laundry treating apparatus is provided which can be manufactured easily. The laundry treating apparatus includes a cabinet, a drum rotatably disposed in the cabinet configured to hold laundry therein, a front cover including a door aperture to load the laundry in the drum, and at least one panel aperture configured to receive a control panel therein. The control panel is mounted on the front cover by means of a mounting plate which is detachably coupled to flange parts. - Applicant has considered the layout of the panel control assembly described in
EP 2140058 . The appliance herein disclosed includes a full front wall, in which two apertures are provided, one for connecting the panel assembly and one for connecting the drawer. - Applicant has noticed that the assembly of the
EP 2140058 machine is rather complex: in order to couple the control panel assembly to the machine, an accurate alignment is required and numerous pieces have to be assembled together in order to obtain the complete panel assembly. Indeed, the presence of several pieces means an increase in the assembly required time and thus an increase in the overall costs of the device. - Applicant has realized that costs are a decisive factor for the success of a laundry treatment appliance, therefore introducing further elements in the construction of the laundry treatment device could most probably increase the costs of the same. Increasing the number of components of the device not only increases costs, but also the time required for the device overall assembly and the numbers of spare parts to make available.
- In addition, the full front wall of the device disclosed in the mentioned EP patent is made of metallic material. As visible from the figures, the panel aperture and the drawer aperture are separated by a crosspiece, which is also made of in metallic material. The control panel is coupled to the casing of the device from the back, e.g. the panel assembly is connected to the front wall from the interior of the casing, and therefore no portion of the panel assembly is overlapping a portion of the front surface of the front wall. This in turn means that the visible and accessible parts of the crosspiece made of metal are also not covered by any additional element, and thus its edges, which are possibly sharp, can cause damage to the user who accidentally touches the same while operating the control panel.
- Last but not least, changes in the layout of a "standard" device causes great influence on production, warehousing and managing cost of the control-panel assembly, and hence of the appliance.
- The Applicant has tackled the problem of devising a satisfactory solution able to overcome the above-discussed drawbacks.
- According to a first aspect, the invention relates to a laundry treatment device comprising:
- ○ a casing housing a laundry treatment chamber and including a front wall defining a continuous front surface, said front wall having a laundry opening to load and/or unload the laundry treatment chamber, a panel aperture and a drawer aperture, said panel aperture and said drawer aperture being separated by a crosspiece;
- ○ a control panel assembly for controlling operation of the laundry treatment device, said control panel assembly including an outer dashboard which is structured to be coupled to said front wall at said panel aperture and to be operated by a user;
- ○ a drawer and a drawer seat to house said drawer, the drawer seat being fixed or fixable to said front wall at said drawer aperture so that said drawer is coupled in a retractable manner to said front wall,
- Preferably, the laundry treatment device is a washing machine or a dryer or a washer/drier.
- The laundry treatment device includes a casing delimiting the appliance, wherein a laundry treatment chamber is housed, and a front wall of the same. The front wall of the casing has a front surface which is a continuous surface having an aperture which is called panel aperture.
- When the front wall is mounted on the rest of casing, an inner volume is defined by the assembly casing and front wall. Element facing said inner volume are called elements which are "inward facing" elements, while elements not facing this inner volume are called "outward facing" elements.
- The front surface of the front wall represents the external front surface of the appliance, thus facing the outside to the casing, and it is advantageously construed as a single continuous surface holed by the panel aperture. In other words, there is a single piece of front wall which hosts, via appropriate aperture(s), a control panel assembly. These front walls are in jargon also called "full front". However, the front wall can also include additional element(s) separated from the portion of the front wall defining the continuous front surface. As an example, the front wall could include a first portion having a panel aperture to host the control-panel assembly which is positioned in the top-most part of the front wall, and a second portion, separated from the first, which covers the lowermost part of the front wall.
- The terms "top", "middle" and "bottom" or "upper" and "lower" are herein used with reference to the standard standing configuration of the laundry treatment device when in use.
- The control panel assembly is manually operated by a user in order to select the programs or to input any data relative to the functioning of the appliance. The control panel assembly can also display warning messages or instruction for maintenance coming directly from the laundry treatment device.
- In addition, the front wall, in the portion defining the continuous front surface, includes further apertures. The front surface includes an opening for the access into the appliance, e.g. in a washing machine or dryer the opening is used to load and/or unload the laundry.
- Moreover, the laundry treatment device includes a drawer. The drawer includes, in case of a washing machine, a detergent dispenser, e.g. the detergent is inserted within the drawer and, during the washing cycle, it is flushed within the drum by flushing water. Alternatively, the drawer is a water drawer where, in case of a dryer, the condense water is collected during the drying cycles.
- The drawer is connected in a retractable manner onto the front wall of the laundry treatment device, at the drawer aperture, so that a user can open and close the same in order for example to introduce the detergents and/or to remove the condense water.
- For this purpose, in the laundry treatment device a seat is provided, in order to house the drawer and allow the opening and closing movements.
- Drawer seat and the dashboard are coupled to two different apertures provided on the front wall, the panel aperture and the drawer aperture, and a crosspiece is interposed therebetween.
- The crosspiece interposed between the two apertures helps to stabilize the front wall, creating a supporting element for the wall, and it also helps to obtain a correct alignment of the control panel assembly and the drawer seat on the front wall during the assembly of the laundry treatment device.
- According to the invention, both the drawer seat and the dashboard are fixed to the crosspiece separating the two apertures one from the other. In this way, the alignment of both drawer seat and dashboard is greatly simplified. This in turn reduces the manufacturing required time and costs. Moreover, the final aesthetical appearance of the laundry treatment device is improved.
- This double fixing is obtained by a first and a second mechanical coupling system (not necessarily two distinct systems, but possibly also two totally or partially coincident systems) which are at least partially included in the crosspiece itself.
- For example, the first and second coupling system may be a same system (i.e. they may coincide). Preferably, they may comprise screw holes provided in the crosspiece and corresponding screws for fixing the dashboard and/or the drawer seat to the crosspiece.
- Alternatively or in addition, first and/or second mechanical coupling system may advantageously comprise hooks formed in the crosspiece to hook corresponding elements in the dashboard and/or drawer seat.
- Clearly also the border/edges of the crosspiece may advantageously be comprised in the first and/or second mechanical coupling system; for example, in a further advantageous embodiment, first and a second mechanical coupling system may comprise a snap fit comprising, for example, a clip provided on the dashboard/drawer seat which is configured to snap on a flat portion of the lateral edges of the crosspiece (which flat portion in this case is comprised in the mechanical coupling system).
- Preferably, all visible portion of said continuous front surface is seamless.
- "Seamless" means in this embodiment that there are no junctions or seams in the front surface connecting different pieces together. Thus, the visible portion of the front wall is a single piece, for example a single metal sheet which has been properly shaped. The sheet has not been welded or otherwise connected. The visible portion of the front wall means that portion which, when the laundry treatment device is in an assembled configuration, is visible by the user from the outside of the casing. This portion is preferably the seamless one, because it gives a better aesthetical appearance to the laundry treatment device and in addition it avoids any possibility of injuries caused by sharp edges which can occurs when seams in metal material are created (for example when the seam is unfinished by mistake). Other portions of the front wall which are covered by additional elements or which are hidden by other casing's parts can include seams.
- Preferably, said drawer seat is integral to said outer dashboard forming an outer dashboard assembly.
- According to the invention, preferably the seat is an integral part of the dashboard. In other words, seat and dashboard form a single integral element.
- In this way, the number of parts which are included in the panel assembly is reduced and the assembly of the laundry treatment device is simplified.
- In addition, when the control panel assembly and the drawer have to be mounted onto the front wall, a correct alignment plays a critical role in order to obtain a satisfactory result. Having to align a single element onto two different apertures, instead of two elements onto the same two different separated elements, again simplifies the overall assembly, reducing costs and time.
- Advantageously, said first mechanical coupling system and second mechanical coupling system are a single coupling system.
- For example, in case outer dashboard and drawer seat are a single element, i.e. the outer dashboard assembly, there is no need of a double coupling onto the crosspiece. A single coupling of a single element onto the crosspiece is enough to obtain all the advantages listed above. The first mechanical coupling system thus coincides with the second mechanical coupling system.
- Also in case of separated drawer seat and dashboard, a single mechanical coupling system can advantageously be present, which can embrace both drawer seat and dashboard and fix both onto the crosspiece.
- In an advantageous embodiment, the outer dashboard or an outer dashboard assembly formed by the drawer seat and the outer dashboard, when coupled to said panel aperture and in an assembled configuration, is completely surrounded by said front wall.
- This means that the outer dashboard or outer dashboard assembly, i.e., including the drawer seat, is surrounded by the front wall. Surrounded can mean that the outer dashboard/dashboard assembly is, in an assembled configuration, in contact to the front wall in all directions. Alternatively, there is no direct contact, but an aperture or another body is interposed between a side of the dashboard/dashboard assembly and the front wall. However, from all sides the dashboard/dashboard assembly is still encircled by a portion of front wall, regardless of whether the front wall is in contact or not to the dashboard/dashboard assembly.
- Surrounded can also mean that any portion of the dashboard/dashboard assembly, not only the external part, can be completely surrounded by the front wall. For example, the dashboard can include a portion external to the casing which covers the front wall to such an extension that it comes into contact to lateral wall(s) of the casing. However, being the dashboard also inserted into the panel aperture, there is always a portion of dashboard/dashboard assembly which is completely surrounded from all directions by the front wall.
- In other words, the dashboard/dashboard assembly is advantageously built-in (or embedded) in the front wall.
- More preferably, said drawer aperture and/or said panel aperture has an edge defining a closed curve.
- The panel and/or drawer aperture includes an edge which is a closed curve, which means that the aperture is completely contained in the front wall. The shape of the aperture and/or of the edge of the aperture is not relevant in the present case and it can be oval, rectangular, etc.
- In a preferred embodiment of the invention, said crosspiece defines a crosspiece front surface, said crosspiece front surface being a portion of said continuous front surface of said front wall.
- In this advantageous embodiment, the crosspiece is not an added element to the front wall, but it is an integral part of the same, and the front surface, which also includes the crosspiece front surface, is globally continuous. More preferably, the whole front surface is also seamless.
- In a different embodiment, the crosspiece can be attached to, for example by welding, the front wall, so it is a separated element that has to be assembled during the laundry treatment device production. Other means to fix the crosspiece are included as well, for example by screws, glue, snap-fit elements, etc.
- More preferably, said outer dashboard and/or drawer seat includes a rear surface, a portion of said rear surface being in abutment against said crosspiece front surface when said laundry treatment device is in an assembled configuration.
- In this embodiment, the crosspiece is substantially covered (or overlapped) by the dashboard and/or drawer seat and thus it is not directly reachable by the user when the laundry treatment device is assembled. The crosspiece therefore is not required to have a proper finishing, such as smooth and rounded edges in order not to injure the user. Indeed, a not covered crosspiece with sharp edges can cut the user's fingers when he/she is operating the dashboard to input some information on the same.
- Advantageously, said first and/or second mechanical coupling includes a screw, screw threads on said outer dashboard and/or drawer seat and a hole on said crosspiece.
- A screw coupling is particularly effective in case of vibrations, such as those present in a laundry treatment device during washing and/or rinsing cycles, and remains fastened.
- Preferably, said drawer seat is coupled to an edge of said drawer aperture by means of a drawer seat mechanical coupling.
- In a depicted embodiment, said drawer seat mechanical coupling includes a screw coupling element.
- To further strengthen the coupling between the drawer seat and the front wall of the laundry treatment device, the drawer seat is also coupled to the drawer aperture.
- In a preferred embodiment, a vertical section of said front wall presents a concavity pointed towards the internal of said casing.
- The shape of the front wall is not flat, but substantially curved. The curvature is along a vertical plane, according to a favorite embodiment, so that the front wall has a rounded appearance which is particularly pleasant and appreciated by the user. In this curved front wall, the dashboard of the invention fits easily due to the fact that preferably the outer surface of the dashboard substantially represents a geometrical continuation of the front surface of the front wall without protruding from the same, i.e. it is flush to the front wall surface.
- Preferably, said outer dashboard is made of a plastic material and said front wall is made of a metallic material.
- Preferably, the front wall of full front laundry treatment devices is made of metal. The full front shape is relatively easily retrievable by suitably bending a sheet of metallic material, such as steel. On the other hand, preferably the dashboard is made of plastic material, because the coupling between plastic and metal is more reliable and easy to be manufactured than a metal to metal connection.
- In another embodiment, said crosspiece is a separated element fixed or fixable to said front wall to separate said panel aperture and said drawing aperture.
- Further features and advantages of the present invention shall become clearer from the following detailed description of a preferred embodiment thereof, made with reference to the attached drawings and given as an indication and not for limiting purposes.
- In particular, the attached drawings are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification. The drawings together with the description explain the principles of the invention. In the drawings, corresponding characteristics and/or components are identified by the same reference numbers. In such drawings:

figure 6 is a top view of casing offig. 3 ; and -
figures 7-9 show three different perspective views of the coupling of an outer dashboard to the front wall of the laundry treatment device offigs. 1-6 . - Referring to the drawings,
Figure 1 schematically shows a perspective view of alaundry treatment device 100 according to the present invention. - As it will be better understood by the following description, the teaching of the present invention may be applied to substantially any appliance for laundry treatment, e.g. to washer/dryers, washing machines (as exemplary illustrated in the figures and to which reference will be made in the following by way of a non-limiting example only), dryers, etc.
- The
device 100 comprises a substantially parallelepiped-shapedcasing 2, which encloses an inner compartment comprising a laundry treatment chamber, for example arotating drum 12 for housing the laundry to be treated and a tub encasing the drum (tub is not visible in the appended drawings). Moreover, the device includes anaccess door 3 provided on afront wall 4 of the casing for accessing thelaundry treatment chamber 12 thereby allowing loading/unloading of the laundry by a user. Thefront wall 4 is connected to an open side ofcasing 2. - The
casing 2, with now reference tofigs. 1-6 , preferably also includes a bottom wall orbasement 5, atop wall 6, aback wall 7, and two oppositelateral walls - Moreover,
casing 2 may include a single wall, or two walls, such as the back and/or one of the side walls. In other words, casing and front wall together defines a substantially close volume, regardless of the relative extension of front wall and the rest of the casing. - Walls are preferably made of metal, however also plastic is possible. Also, in a non-depicted embodiment, some of the walls can be made of a material, and some other(s) can be made of a different material.
- By the
device 100 itself, in a standard operative position, a horizontal plane is defined (plane (XY) inFigure 1 and3 ), which is generally the plane on which the bottom wall orbasement 5 lies and generally it is also parallel to thetop wall 6 of the casing in a mounted configuration. The appliance also extends along a vertical direction denoted with Z. - In a preferred embodiment, the
front wall 4 includes an externalcontinuous surface 4a having a plurality of apertures, as better detailed below. According to a preferred embodiment, the front external surface is the external front surface of the appliance. -
Front wall 4 is preferably made of a metallic material, for example in stainless steel. - The
front surface 4a is preferably continuous and even more preferably seamless, at least in the visible portion(s) of the same. Continuous surface means that the surface is formed as a single member. "Seamless" means that, in addition to be continuous, there are no seams which indicate that for example welding has been used to join together different parts. In the covered (i.e., not visible from outside of thelaundry treatment device 100 in the assembled condition of the latter) portions of thefront wall 4, seams can be present. The absence of seams improves the overall appearance of thelaundry treatment device 100. - In addition, the
front wall 4 preferably includes four roundedcorners device 100. - In an embodiment of the invention, the
front wall 4 can be obtained by a single sheet of metal. For example, it can be obtained by a sheet of stainless steel. In addition, the front wall can be coated by suitable coating to prevent corrosion. Moreover, the front wall can be colored of any color and gloss. - Preferably, the
front wall 4 defines atop portion 4a', amiddle portion 4a"' and abottom portion 4a", the terms "top", "middle" and "bottom" used with reference to the standard standing configuration of the household appliance when in use. - In a preferred embodiment, not depicted in the drawings, only the
top portion 4a' and themiddle portion 4a"' of thefront wall 4 are a single (or one-piece) element, i.e., having a continuous and/or seamlessfront surface 4a, while thebottom portion 4a" can be permanently fixed to it, for example welded to it, or it can even be added as an additional element which can be disassembled from the rest of the front wall. - In addition, the
front wall 4 includes an outer edge which can be divided in atop edge 50a, which is the portion of the outer edge comprised betweencorners bottom edge 50b, which is the portion of the edge located betweencorners corners -
Front surface 4a includes alaundry opening 3a for the access into thelaundry treatment device 100, in particular to thelaundry treatment chamber 12 so that laundry can be loaded or unloaded to/from thelaundry treatment device 100. Theopening 3a is openable and closable by thedoor 3, which is advantageously hinged onfront wall 4. - Preferably, the
door 3 is coupled to a recessedportion 3b of thefront wall 4a: in this embodiment, thefront wall 4 includes the recessed portion (seefigures 3 and4 ) in the center of which thedoor opening 3a is formed. The dimensions of theopening 3a are such to be suitable to accommodate thedoor 3. Thedoor 3 is then rotatably coupled to thedoor opening 3a and, when mounted and in a closed position, it preferably does not project substantially beyond thefront surface 4a due to the recess presence. In other words, an outer surface ofdoor 3 matches thefront surface 4a offront wall 4. - Preferably, but not necessarily, the
door 3 and the recessedportion 3b are located in themiddle portion 4a"' of thefront wall 4. - Advantageously, the
front wall 4 is not flat, i.e., it does not lie completely on a single plane. On the contrary, it preferably includes a concavity pointing towards the inside of thecasing 2, being convex on the outside. In the depicted embodiment, better visible in the side view offig. 5 , the front wall 4 - in a section along plane parallel to plane (Z, Y) - has substantially a smoothed trapezoidal shape, the top 4a', the bottom 4a" and themiddle portion 4a"' lying on three different planes which form an angle one with respect to the other(s) and also with the vertical direction Z defined by thecasing 2, forming in this way the inward concavity. The three planes are preferably connected smoothly and without sharp corners, as clearly visible infigure 5 . However, other layouts of thefront wall 4 are possible as well, for example the front wall can include a substantially constant curvature, the concavity still oriented towards the inside of thecasing 2. For example, the front wall could be a portion of a cylindrical mantel. - Preferably, a first and a
second side walls front wall 4, extending from itsside edges corners 4b-4e and 4c-4d, respectively.

-
Control panel assembly 1 is coupled to thefront wall 4 at thepanel aperture 15. ThePCB 14 and other possible elements are inserted into theaperture 15. Theouter dashboard 11 is then fastened onto thefront wall 4. The external portion 11ext preferably remains outside thecasing 2 andfront wall 4, for example abutting onto thefront surface 4a and/or onto theedge 15a of theaperture 15. - With now reference to
figures 7-9 , in order to securely fasten thecontrol panel assembly 1 to thepanel aperture 15, first and secondmechanical elements edge 15a of the same, in a firm manner, withstanding also possible device's vibrations present during the washing and/or rinsing cycles. - In the depicted embodiment, the first
mechanical element 20 advantageously includes one or more snap-ontongues 22 provided on thedashboard 11 and a correspondingflange 16 formed around theedge 15a of saidpanel aperture 15, so that thetongues 22 can clip on theflange 16. - Moreover, the second

figures 7-9 . However any other type of "double coupling" is feasible as well. In addition, a single mechanical coupling system can be used to fasten thecontrol panel assembly 1 to thepanel aperture 15. - Furthermore, with reference still to
figures 7-9 , theouter dashboard 11 is preferably fastened to thecrosspiece 66 via a first mechanical coupling system 67. Thecrosspiece 66 itself comprises at least an element, part or portion of such first mechanical coupling system. In this specific embodiment, the crosspiece includes ahole 64 of the first mechanical coupling system 67, on which ascrew 69 is inserted and fastened into ascrew thread 68 provided on the rear surface 11a of theouter dashboard 11. More preferably, twoholes 64, one on top of the other in the vertical direction Z are provided also on thecrosspiece 66, on which two screws are inserted, which are then screwed into two screw threads formed on therear surface 11r of the outer dashboard. - Other mechanical coupling systems can be used as well, as long as the crosspiece includes a part of the system to fasten the dashboard to itself.
- When the
dashboard 11 is coupled to the front wall at thepanel aperture 15, there is at least a portion of thedashboard 11 which is completely surrounded by the front wall. In other words, thefront wall 4 embraces at least a portion of the dashboard which, in all possible directions, is embraced by the front wall. As better visible infigs. 7 - 9 , thedashboard 11 includes, extending from itsrear surface 11r, a flange orridge 19 which is inserted in the aperture. Theflange 19 is abutting against theedge 15a ofaperture 15 and it is completely surrounded by the same, e.g. in the depicted embodiment the portion of the dashboard calledflange 19 is completely surrounded by thefront wall 4 and in particular by theedge 15a (part of front wall). - In a different embodiment, not shown in the figures, in which there is no
crosspiece 66 separating panel aperture and drawer aperture, a wider aperture is present to house both control panel and drawer. In this embodiment, on the side of theflange 19 where in the previous embodiment the crosspiece was present, now a portion of the aperture is present for housing the drawer. Also in this embodiment, the dashboard is still surrounded in all directions by the front wall, because beyond the portion of aperture, along a horizontal axis for example, a piece on front wall is still present, the piece of front wall which forms the edge of the "wider" aperture. - In a further embodiment, not shown, the external portion of the dashboard extend along the front surface and can cover the
front wall 4 up to thecasing 2 in one or more some directions. For example, the external portion of the dashboard 11ext can reach one (or more) of the casinglateral walls top wall 6, if it extends along a horizontal, or vertical, direction, thus without leaving portions of the front wall between the dashboard and the casing visible in that direction. However the dashboard is still completely surrounded by the front wall also in this embodiment, due to the fact that theflange 19 is still inserted inaperture 15 and thus edge 15a completely surrounds theflange 19. - Preferably, when the
dashboard 11 is coupled to thefront wall 4 and it is inserted partly in thecasing 2, the external portion 11ext of thedashboard 11 is flush-mounted on thefront wall 4, being flush with thefront surface 4a. The aesthetical appearance of the assembleddashboard 11 on thefront wall 4 is that of a substantially continuous surface where the external portion 11ext matches theexternal surface 4a offront wall 4. -
Laundry treatment device 100 also includes adetergent drawer 63.Detergent drawer 63 is retractably mounted to saidfront wall 4 so that it can be opened and closed. The detergent drawer is generally used to introduce detergents or other products in order to perform a proper washing cycle. Detergent drawer includes a detergent drawerfront wall 63a, which also remains external to thecasing 2 when the laundry treatment device is in an assembled configuration, and it is so shaped to be easily gripped by the user in order to open and/or close thedrawer 63. -
Drawer 63 is coupled todrawer aperture 60 offront wall 4. In order to couple the drawer to thefront wall 4 in a retractable manner, adrawer seat 61 is provided, whose dimensions are optimal to house thedrawer 63 in a slidable manner. Thedrawer seat 61 is thus fixed to thefront wall 4 at thedrawer aperture 60. -
Drawer seat 61 is preferably made of plastic material. -
Drawer seat 61, after being mounted on thedrawer aperture 60, is then covered by the drawerfront wall 63a so that drawer seat becomes substantially invisible when thelaundry treatment device 100 is in an assembled configuration.Drawer front wall 63a thus is positioned in front of thedrawer aperture 60 closing the same. Preferably, thefront wall 63a of the drawer is mounted on the drawer seat so that it is substantially flush-mounted to the front wall, i.e., thefront surface 4a of the front wall is substantially flush with a front surface of the drawerfront wall 63a. - In an alternative embodiment, non-depicted in the drawings, a single "larger" aperture is provided, as mentioned previously, to house both the
control panel assembly 1 and, adjacent to the latter, the detergent drawer 63 (so the crosspiece is not present). - With now reference to
figures 7-9 , the fastening of the dashboard and the drawer seat to the front wall is shown. -
Drawer seat 61 is inserted intodrawer aperture 60 and then fixed to the same. In order to fix thedrawer seat 61 to thefront wall 4, amechanical coupling 65 is used.Mechanical coupling 65 includes for example ascrew 65a inserted into ahole 65b provided in proximity of theedge 60a of thedrawer aperture 60. Thescrew 65a is thus screwed into a screw thread (not shown) of thedrawer seat 61. Any other mechanical coupling can be used as well, in order to firmly fasten the drawer seat to thedrawer aperture 60, preferably in proximity of thedrawer aperture edge 60a. - The
drawer seat 61 is also preferably fastened to thecrosspiece 66 via a second mechanical coupling system 67. Thecrosspiece 66 itself comprises at least an element of such second mechanical system. In this specific embodiment, thecrosspiece 66 includes ahole 64 of the second mechanical coupling system, on which ascrew 69 is inserted and fastened into ascrew thread 68 provided in the rear surface 11a of thedrawer seat 61. More preferably, twoholes 64, one on top of the other in the vertical direction Z are present atcrosspiece 66, on which two screws are inserted, which are then screwed into two screw threads. - In the depicted embodiment,
drawer seat 61 and the external portion 11ext of theouter dashboard 11 form an integral piece, forming an outer dashboard assembly. Therefore, first and second mechanical systems 67 are a single system, because fastening of one of the dashboard and drawer seat to the crosspiece automatically means fastening the other of the drawer seat and dashboard to the crosspiece. - However, a non-depicted embodiment in which the drawer seat and the dashboard are separated elements one from the other and independently fixed to the crosspiece via different first and second coupling systems is envisaged as well by the present invention. Moreover, first and second mechanical coupling systems can be different one from the other, for example one of them might include a snap-fit system and the other one a screw coupling system. In all cases, the crosspiece includes a part of both the first and second mechanical coupling system.
- Preferably, the external portion 11ext of the
dashboard 11 anddrawer seat 61 are molded together and are made of plastic material. - A connecting element, called
bridge 101, joins together the dashboard external portion 11ext and thedrawer seat 61.Bridge 101 is preferably located outside thecasing 2 when the laundry treatment device is in an assembled configuration and it is positioned in front of thecrosspiece 66. Thebridge 101 includes acover surface 101a, which is not visible to a user from the outside of the casing when thecontrol panel assembly 1 is in an assembled configuration and connected to thefront wall 4. -
Cover surface 101a can be a portion of therear surface 11r ofdashboard 11 or a different separated surface. Cover surface, as the name suggests, covers thecrosspiece 66, and preferably thefront surface 66a of the same. - In the embodiment in which the drawer seat and the dashboard external portion are two different separated elements, the
cover surface 101a can alternatively be included in thedrawer seat 61 or in thedashboard 11 and its function is still the same, to cover thefront surface 66a of thecrosspiece 66. - Preferably, the
cover surface 101a is in abutment against thefront surface 66a of the crosspiece. - General operation of the
laundry treatment device 100 is substantially identical to that of a conventional laundry treatment device, therefore no further explanation is required. - It has thus been shown that the present invention allows all the set objects to be achieved.
- Clearly, changes may be made to the rotatable drum and to the laundry treating machine (including such a rotatable drum) as described herein.
- Although an illustrative embodiment of the present invention have been described herein with reference to the attached drawings, it is to be understood that the present invention is not limited to the specific embodiment illustrated and described herein, and that various other changes and modifications may be affected therein by one skilled in the art without departing from the scope of the invention.
