Definitions

  • the present invention relates to a recess-mountable electric household appliance comprising a front loading door hinged to one edge and provided with a control panel on a top edge, and comprising an electromechanical programmer received in said front door with a shaft lying perpendicularly to the front wall of said door, the programmer being operable by means of a generally disk-shaped knob keyed to its shaft and located on the inside of said door between said programmer and said front wall said disk-shaped knob being provided on its periphery with manual actuation means carrying alphabetic, numerical or coded program references impressed on its outer surface.
  • Examples of recess-mountable electric household appliances are the dishwashers which are intended for installation inside kitchen furniture of the assembly type having homogeneous aesthetic features, under a work surface disposed at a height on the order of 80-85 cm above floor level.
  • a demand is that programming the machine for work and visually checking the settings performed be an easy and ergonomic operation to carry out.
  • control and display members which are inconsistent with the modular aesthetic features of the host furniture and with the provision of a "matched" ornamental panel spanning the full height of the machine front should be avoided.
  • the control panel By opening the door at least a crack, the control panel, suitably disposed on the top edge of the door, becomes accessible for the necessary setting operations.
  • a knurled knob keyed to the shaft of a conventional electromechanic programmer, oriented perpendicularly to the machine front, can be operated.
  • the cylindrical peripheral surface of the knob accessible for programming purposes, carries numerical or coded references which make the selected settings readable.
  • An example of this technology is disclosed in GB-A-2,269,002, with reference to a dishwashing machine.
  • the top edge of the door may be protected, with the door closed, by the work surface overhanging it, the ingress through the programming knob window of liquid or solid matter, potentially harmful to the device, cannot be ruled out with the door partially open.
  • the actuating means may consist of a knob peripheral cylindrical annulus having a surface with a high frictional coefficient, or of a cogged belt made of a resilient material, and being in mesh engagement with a corresponding toothing on the knob and stretched between the knob and a deflector pulley.
  • the dishwasher of the recessed-mount type comprises a front loading door 1 hinged downwardly to a body 2 which is recessed under a work surface 3, or another household appliance such as an electric and/or microwave oven.
  • the work surface or superposed household appliance, overhangs the body by an amount which is at least equal to the thickness of the front door.
  • the top edge of the door is formed by a profiled template 4 which spans the full width of the door and is continuous with the front wall and the side edges of the door.
  • the front wall of the door is covered with a plastics laminate 5 whose pattern, color and finish are harmonized with those of the host furniture.
  • the door 1 is closed rearwardly by an inner door 6 which is sealed to the edges 21 of the machine loading opening.
  • an electromechanical programmer 7 Accommodated between the front wall of the door and the inner door is an electromechanical programmer 7 having a shaft 8 perpendicular to the front wall.
  • a disk-shaped programming knob 9 is keyed to the shaft 8, close against the door front panel.
  • the disk-shaped knob 9 is provided with a cylindrical annulus 12 on its periphery. This is suitably knurled with raised ribs 11 to produce a suitable mechanical friction and enable a torque to be applied for manually turning the knob through an actuation opening 10.
  • the opening 10 is advantageously formed in a head of the profiled template 4, correspondingly with a side edge of the door and exposes a sector of the cylindrical annulus 12 of the disk-shaped knob 9.
  • a sector of the cylindrical bezel 12 locates opposite a window 13, in the form of an elongate slit cut in the top edge of the door, formed by the template.
  • the window 13 is covered by a clear protective screen 14 which is snap fitted, by means of holding teeth 17, 18, over the window 13, and through which the program digits on the cylindrical bezel can be viewed.
  • the window 13 Since the window 13 is open upwards, the reading is particularly easy, because it is effected from a point of view located essentially above the window 13 whose opening plane is oriented perpendicularly to the point of view.
  • the operation of the knob is also particularly easy through the opening 10, whose location on a side edge of the door virtually avoids the risk of falling liquids or solid elements getting inside the opening 10 from above.
  • the screen 14 provides a similar protection for the window 13 opposite the top edge of the door.
  • the template 4 which forms the top edge of the door is suitably provided with an inner plate 15 which extends parallel to the front wall of the door and acts as a holder for the programming device 7 and perhaps other control or display devices.
  • the knurled finish of the knob may be replaced with suitable corrugations of another type, such as coatings effective to enhance roughness, ensure a high frictional coefficient, and in all cases to permit rotation of the knob by hand.
  • suitable corrugations of another type such as coatings effective to enhance roughness, ensure a high frictional coefficient, and in all cases to permit rotation of the knob by hand.
  • the high frictional coefficient can also be obtained by fitting the knob with an annular ring of a material, such as rubber, which has an inherently high coefficient of friction.
  • Figure 5 shows a front section through a second embodiment of the present invention, wherein both the display window 13 and the knob actuation opening 10 are facing the top edge of the door.
  • the knob 9 has, on its cylindrical outer surface, a cylindrical toothing 23 which meshes with a toothing 24 formed on the inward face of a belt 25 which is trained partially around the knob 9 and extends to a cogged deflector pulley or wheel 26.
  • Numerical, alphabetic or coded program references are impressed, preferably by hot padding or some equivalent wear-resistant indelible method, on the outer surface of the belt, as suitably roughened or imparted a high frictional coefficient.
  • the developed pitch line of the belt is an N (2, 3, or more) multiple of the developed pitch line of the knob toothing, so that the program references, being orderly repeated N times on the belt, will always be in the same phase relationship to the angular position of the knob.
  • the timing of the belt and knob can be ensured by mutual referencing, preferably using a tooth with twice the pitch of (more generally a different pitch from) the rest and a corresponding groove, respectively disposed on either of the two knob and belt elements.
  • the knob 9 and deflector pulley 26 are arranged such that a substantially straight section of the belt extends close to the top edge of the door and is simultaneously facing the window 13 and opening 10.
  • the window 13 and opening 10 may be placed a suitable distance apart, so that the operation of the knob through the opening 10, by acting on the belt, will not impair a comfortable readability of the belt portion facing the window 13.
  • the opening 10 preferably locates at a zone of the belt which is at least in part supported by the knob
  • the window 13, through which no mechanical action is applied to the belt may open to any zone of the straight section and requires no opposed inner support, although it does not exclude one.
  • Figure 5 may be altered by providing a display window opposite the top edge of the door and an actuation window accessible from a side edge of the door to secure all the benefits mentioned in connection with the embodiment described with reference to Figures 1 to 4, with the added advantage of affording great freedom of spaced-apart spatial positioning of the display window relative to the actuation opening.
  • the invention is susceptible of application to any types of recess-mountable electric household appliances, with a control panel which includes an electromechanic programming device.
  • a control panel which includes an electromechanic programming device.
  • the cooking time can be programmed by means of an electromechanic knob timer, and this can be concealed as per the teaching provided herein.
