Definitions
- the present invention refers to a device for the selection of washing programs for washing machines, in particular, though not exclusively, dishwashers of the integrally built-in type.
- a frontal covering generally consisting of a full height covering panel on the access door of the washing tank, which has aesthetic features that are homogeneous with the rest of the kitchen furniture.
- control panel which typically comprises a device for the selection of the operating program, and a number of other switches, among which a master switch to start the machine
- the selection of the washing programs is accomplished by means of a knurled dial with axis orthogonal to the door front face, mortised on the driving shaft of a conventional electromechanical timer, that is also oriented in such a way as to have the driving shaft perpendicular to the door front face.
- a window in the upper edge of the door allows to reach by hand the cylindrical outer surface of the dial, which bears numerical or symbolic references enabling to visualise the selection being made.
- an object of the present invention is to provide for a device for the selection of washing programs for an integrally built-in washing appliance, in particular for an integrally built-in dishwasher, that solves the problem encountered with the known devices, and in particular the problem dealing with housing the programmer inside the door.
- a device for the selection of washing programs for a washing appliance comprising an access door to a washing tank that is hinged at its lower edge to a frame of said washing appliance, characterised in that it includes a turning knob with an axis of rotation substantially orthogonal to an upper edge of the door and coupled to a driving shaft of a rotary selector operatively connected to a programmer mounted within said frame, the rotation of the knob allowing to set the rotary selector, a housing suitable to contain said knob being provided on the upper edge of the door.
- Figure 1 shows in a schematic axonometric view a dishwasher of the so-called integrally built-in type.
- the dishwasher comprises a frame 1 to be embedded in a specifically designed space in a kitchen furniture. Inside frame 1 a washing tank 2 is housed. Frame 1 and washing tank 2 have a front opening acceding to the same washing tank. Said front opening is closed by means of a door 3 hinged to the frame 1 in correspondence of its lower edge 4. The door 3 is frontally coated with a full height covering panel 5. Above the frame 1 lays a worktop 6 belonging to the kitchen furniture. The worktop 6 abuts frontally with respect to the frame 1, in such a way that when the door 3 is close, its upper edge 7 remains totally covered by the worktop 6.
- a control panel which comprises a device for the selection of the washing programs 8 of the dishwasher, comprising a retractable knob 9, that will be described in greater details later.
- the device for the selection of washing programs 8 controls a programmer 12 that, unlike what is done conventionally, is not located within the door 3, but in a more spacious zone of the dishwasher, as for example inside the frame 1 under the washing tank 2; obviously other positions are also possible.
- the device for the selection of washing programs 8 is operatively connected to a programmer 12, in such a manner that the selection of the program made by means of the device for selection 8 is communicated to the programmer 12 which governs the operation of the dishwasher.
- a master switch 100 is also located, in a known manner, which controls the start and switch off of the dishwasher.
- FIG. 1 another switch, provided for safety, is schematically shown comprising a micro-switch 10 placed on a frontal upper edge of the frame 1 and an actuator pin 11 placed on an internal wall of the door 3 in correspondence of the upper edge 7.
- the micro-switch 10 and the actuator pin 11 are kept at a distance and the dishwasher cannot operate, even if the master switch 100 is in an on position.
- the switch 10 is activated by the pin 11 and the dishwasher starts working according to the selected program.
- Figure 2 shows, in section according to a plane orthogonal to the panel 5 and to the upper edge 7 of the door 3, a portion of the latter in which a housing 77 is created for accomodating a device for the selection of washing programs 8 according to a first embodiment of the present invention.
- the device 8 comprises a turning knob 9, housed in a seating created in the upper edge 7 of the door 3.
- the knob 9 is mortised on a driving shaft 13 of a rotary selector 14 known per se, as for example the "resistive switch" produced and marketed, among others, by REMCO.
- the rotary selector 14 is fixed to a flange 15 projecting at square angle from a front wall 16 of the door 3 on which the covering panel 5 is applied, and has power terminals 17 connected, by means of respective conducting wires 18, to the programmer 12 housed for example in frame 1, under the washing tank 2, or in any case located in a different position with respect to the selection device 8, in any position where there is enough space to accommodate it.
- the programmer 12 is a traditional electromechanical timer, for example of the kind known on the market as EATON model ECR, or ELBI series 5000 or CROUZET model TMX, with two motors (one of quick rotation for the selection of washing programs, and the other with normal rotation speed during the execution of a program), or with one single double-speed motor providing for the quick selection of the washing programs and the normal rotation speed during the execution of a program.
- the knob 9 comprises an external body 19 substantially of cylindrical shape, and an internal body 20.
- the internal body 20 is mortised on a shaft 13 of the rotary selector 14; the external body 19 is sliding along the internal body 20 between two extreme positions, a position completely retracted (shown by dots and dashes in Figure 2 and as a continuous line in Figure 3) in which the upper surface of the external body 19 is substantially at the same level of the upper edge 7 of the door 3, and an extended position in which the external body 19 partially projects from the upper edge 7 of the door 3, in such a way as to enable the user to grab the external body 19 and to rotate it in order to select the desired washing program.
- the door 3 can be closed, as the knob 9 does not interfere with the edge of the worktop 6 above the dishwasher.
- the external body 19 comprises in addition a cylindrical band 21 on which indexes 22 are created that, when the external body 19 is extended, co-operate with a fixed index 23 located on the upper edge 7 of the door 3 in order to visualise the selection being made.
- the user For the selection of the washing programs, the user must previously open the door 3 thus making the upper edge 7 of the door 3 accessible, then must press the external body 19 of the knob 9 in such a way that the locking/unlocking means mutually disengage and the elastic means determine the exit of the external body 19; at this point, acting with a rotation of the knob 9, and with the aid of the indexes 22 and the fixed index 23, the user can select the required washing program. Then, by pressing again the external body 19 of the knob 9 determines its retraction, and the locking/unlocking means block the external body 19 in the retracted position. The user must therefore press the master switch 100. By closing the door, the connections 10, 11 of the dishwasher starter switch get closed and the dishwasher can start operating, under the control of the programmer 12, according to the selected washing program.
- Figure 4 shows a variation of the device shown in Figures 2 and 3; the upper surface 26 of the external body 19 is rounded, and frontally to the dishwasher a plate with a rounded projection 25 extends. In this way. it is possible to close the door 3 even when the external body 19 of the knob 9 is in the extended position: when the rounded surface 26 comes into contact with the rounded projection 25, the latter determines automatically the retraction of the external body 19 of the knob 9. By means of a proper sizing, it can also be provided that upon opening the door the external body 19 of the knob 9 automatically comes out.
- Figures 5, 6 and 7 show a device for the selection of washing programs 8 according to a second embodiment of the present invention.
- the knob 9 consists of a single piece, substantially of cylindrical shape, that is mortised directly on the driving shaft 13 of the rotary selector 14.
- the shaft 13 is solidly fixed to a shaft 27 of a switch 28. More precisely, on the lower edge of the shaft 27 a support 29 is fixed on the lower side of which a conducting plate 30 is applied.
- a support 31 is mounted from which two contact plates 32 extend which are connected to two power terminals 33.
- the shaft 13 and the shaft 27 are sliding in the direction of their common axis, between two extreme positions in one of which (shown in Figure 5) the knob 9 protrudes with respect to the upper edge 7 of the door 3 and simultaneously the support 29 is far from the two contact plates 32 of the switch, while in the other position (shown in Figure 6) the knob 9 is retracted and at the same time the support 29 is near the two contact plates 32, in such a way that the latter can be electrically connected through the conducting plate 30 establishing a power connection between the terminals 33 of the switch 28, that is therefore close.
- the invention provides for elastic bias means of the knob 9 in the extended position, and locking/unlocking devices that, when the knob is pressed, maintain the latter in a retracted position, while when the knob 9 is pressed again release the knob which can protrude from the edge under the thrust of the elastic means.
- a portion 50 of the outer cylindrical surface of the knob 9 is toothed, and it engages with a rack 51 mounted on a bracket 52 extending below the lower edge 7 longitudinally to it; the bracket 52 bears some indexes 53 corresponding to the different washing programs, and that can be read by the user through a window 54 located in the upper edge 7 of the door 3; on the latter there is also a fixed index 55 that co-operates with the indexes 53 on the bracket 52 in order to indicate the selected program.
- Turning the knob 9, determines the slide of the bracket 52 and therefore the displacement of the indexes 53 with respect to the fixed index 55.
- This system of visualisation of the selected programs could naturally be used also in combination with selection device 8 according to the previously described first embodiment.
- the upper surface of the knob 9 could be rounded, and could be provided with the rounded projection 25 shown in Figure 4, in such a way that the knob would retract automatically when the door 3 gets closed.
- Figure 8 shows a device according to a third embodiment of the present invention.
- the device comprises a turning knob 9 with axis substantially orthogonal to the upper edge 7 of the door 3.
- the knob 9 is housed in a seating 77 made in the edge 7, and it is coupled, by means of a pin joint 79 of the type described in the European Patent application No. 95200392.9 in the name of the same Applicant, to a driving shaft 13 of a rotary selector 14; as it can be seen from the Figure, the selector 14 is mounted inside the door at an inclined position, fact that allows to reduce the volume taken up transversally by the selector 14, and its driving shaft 13 is inclined with respect to the axis of rotation of the knob 9.
- the pin joint 79 it is possible to operate the selector 14 through the knob 9.
