Definitions

  • the present invention relates to a worktop of a household appliance, in particular of a dishwasher, a washing machine or a drying machine, and to a method of manufacturing a worktop of a household appliance.
  • washing machines laundry washing machines and dishwashing machines
  • drying machines have a machine structure or body (usually made of metal sheets) which houses internal components and is open at the top; the top of the machine structure is normally closed by a cover plate, usually formed by a wooden panel surrounded by a plastic frame, which also define a worktop for the user and therefore commonly named "worktop".
  • the worktop is usually connected to the machine structure by fastening elements which engage respective seats formed in the machine structure.
  • the frame is manufactured in the form of an open ring which is integrally provided with the fastening elements; the fastening elements do not hamper the insertion of the panel since the open ring of the frame may be easily deformed to be positioned around the panel edge; after positioning around the peripheral edge of the panel, the open-ring frame is closed by a joint; the frame is then firmly connected to the panel by metal clamps.
  • This kind of worktop is relatively easy and cheap to be realized, but has the drawback that the frame has a cut and a joint in the visible part of the worktop, which is not appreciated by users and customers.
  • the plastic frame consists of a monolithic continuous ring-shaped body, which is glued to the panel; the fastening elements for connection to the machine structure are glued directly to the bottom surface of the panel.
  • this solution is quite expensive (mainly because glue is needed) and the assembly process is also relatively complicated, since it is necessary to correctly position the fastening elements on the panel.
  • a worktop of a household appliance in particular of a dishwasher, a washing machine or a drying machine, fittable to an appliance structure and comprising a panel, having a peripheral edge, and a frame, coupled to the peripheral edge of the panel and consisting of a monolithic ring body defining a continuous closed loop; the worktop being characterized in that the monolithic ring body of the frame is integrally provided with fastening elements clamping the panel and connected to the frame by respective plastic film-hinges.
  • a method of manufacturing a worktop of a household appliance in particular of a dishwasher, a washing machine or a drying machine, the worktop comprising a panel, having a peripheral edge, and a frame, coupled to the peripheral edge of the panel and consisting of a monolithic ring body defining a continuous closed loop; the method comprising the steps of:
  • the worktop according to the invention has therefore a fully satisfactory aesthetical appearance, since the frame consists of one single-piece closed ring which does not has any cut or joint; at the same time, the worktop is realized by an easy and low-cost manufacturing method.
  • number 1 indicates an electric household appliance of any type, for example a dishwasher; nevertheless, the following description also applies to any other type of appliance, such as a washing machine, drying machine, refrigerator, freezer, oven, etc.
  • Appliance 1 comprises an appliance structure 2, generally known and therefore not described nor shown in details for the sake of simplicity, and a top cover plate defining a worktop 3, which is fittable to structure 2 by connection members 4.
  • Structure 2 comprises a substantially prismatic casing 5, which houses internal functional components (not shown) of appliance 1; a top end 6 of structure 2 is open to enable assembly of the functional components inside; worktop 3 is so formed as to mate with top end 6 of structure 2 and provides for closing top end 6 while at the same time forming a supporting surface for the user.
  • Connection members 4 comprise for example connection blocks 7 carried by worktop 3 and engaging respective connection seats 8 formed in structure 2, for example in two cross bars 9 at top end 6 of structure 2.
  • Worktop 3 comprises a panel 10 delimited by an outer peripheral edge 11, for example a substantially flat panel having a substantially quadrangular (e.g. square or rectangular) shape; and a frame 12, coupled to the whole profile of peripheral edge 11.
  • Panel 10 has a top surface 13 (intended to be visible in use) and an opposite bottom surface 14 facing structure 2.
  • Panel 10 is made of wood and/or plastic layers, or other suitable materials; frame 12 is preferably made of a plastic material.
  • frame 12 consists of a monolithic ring body 15 defining a continuous closed loop.
  • Frame 12 has a substantially quadrangular shape (possibly with rounded corners and/or curved sides) and comprises a base wall 16, substantially parallel to panel 10 and having a front surface 17 and a rear surface 18; and a lateral wall 19, projecting from an outer perimetral edge of rear surface 18 and substantially perpendicular to base wall 16.
  • Base wall 16 delimits a central opening 21; front surface 17 is intended to be visible in use, while rear surface 18 defines a bottom shoulder 23 that contacts top surface 13 of panel 10.
  • Frame 12 is internally provided with an inner perimetral seat 25 matching the profile of peripheral edge 11 of panel 10 and housing peripheral edge 11.
  • seat 25 has a non-symmetrical substantially C-shaped cross-section and contacts top and bottom surfaces 13, 14 of panel 10; seat 25 is delimited by shoulder 23, that contacts top surface 13 of panel 10, and by an inner wall 26, substantially parallel to shoulder 23 and contacting bottom surface 14 of panel 10.
  • Frame 12 is integrally provided with a number of fastening elements 27, 28 clamping panel 10 and connected to frame 12 by respective plastic film-hinges 29.
  • Fastening elements 27, 28 project from an inner perimetral edge 30 of inner wall 26 to face shoulder 23 and are spaced apart from one another along inner perimetral edge 30; fastening elements 27, 28 are positioned on at least two opposite sides of frame 12.
  • frame 12 is provided with main fastening elements 27, intended to both clamp panel 10 and connect frame 12 to structure 2, and auxiliary fastening elements 28 intended only to clamp panel 10.
  • each fastening element 27, 28 comprises a substantially flat base portion 32 contacting bottom surface 14 of panel 10 and projecting from inner wall 26; base portions 32 are connected integrally to inner wall 26 by flexile portions 33 which define film-hinges 29.
  • flexile portions 33 consist of narrowed cross-section strap portions, having a thickness less than the thickness of both base portions 32 and inner wall 26.
  • Auxiliary fastening elements 28 ( Figure 5 ) are provided with stiffening ribs 34 projecting from base portions 32 opposite to panel 10.
  • Each main fastening element 27 ( Figure 6 ) comprise instead a base portion 32 and a connection portion 35, which is integrally formed with base portion 32 and project from base portion 32 opposite to panel 10; connection portions 35 are provided with connection blocks 7 which are fitted to respective connection seats 8 of structure 2 and locked in seats 8 in known manner (e.g. by means of screws, not shown).
  • Panel 10 is housed in perimetral seat 25 and clamped between shoulder 23 and fastening elements 27, 28.
  • Fastening elements 27, 28 are coupled to panel 10 by fixing elements 36 (only some of which shown in Figures 1 and 5-6 ) engaging base portions 32 and panel 10.
  • fixing elements 36 are metallic clamps passing through base portions 32 and engaging panel 10.
  • a film 37 of sealing material ( Figure 1 ), e.g. a film of vaseline, is interposed between peripheral edge 11 of panel 10 and frame 12.
  • the manufacturing method of worktop 3 is as follows.
  • Frame 12 is manufactured by moulding, in particular injection moulding, a suitable plastic material (preferably a thermoplastic material); the whole frame 12, consisting of body 15 integrally provided with fastening elements 27, 28, is moulded in one moulding step.
  • a suitable plastic material preferably a thermoplastic material
  • Film 37 of sealing material e.g. vaseline, is applied onto peripheral edge 11 of panel 10.
  • fastening elements 27, 28 are rotated around respective film-hinges 29 so as to move fastening elements 27, 28 away from shoulder 23; then panel 10 is inserted in frame 12 and specifically in seat 25 and against shoulder 23; film 37 of sealing material remain interposed between peripheral edge 11 of panel 10 and frame 12; fastening elements 27, 28 are then counter-rotated around film-hinges 29 towards shoulder 23, so as to clamp panel 10 between fastening elements 27, 28 and shoulder 23.
  • fastening element 27, 28 are firmly and permanently connected to panel 10 by fixing elements 36, i.e. by penetrating metallic clamps through base portions 32 of fastening elements 27, 28 and in panel 10.
