This application claims priority to Spanish Patent Application No. P200900398, filed Feb. 13, 2009.
The invention relates to cooking tops, and in particular to control panels for cooking tops.
There are known cooking tops comprising lighting elements that are located beneath a plate.
European Patent Application No. EP1569057A2 discloses a control panel for domestic appliances having buttons that are highlighted by lights to assist the user. The buttons are visible at all times although they are not always illuminated.
European Patent No. EP1050194B1 discloses a cooking plate with lighting elements located beneath the plate. Indicator symbols are created by the use of lighting elements and masks and are not printed on the cooking plate. The operating elements, on the other hand, are permanently visible either because they are printed on the surface of the plate, or because they are built into the frame of the plate.
In one implementation a control panel for a cooking top is provided that includes a translucent plate, a plurality of indicating elements where at least some of the indicating elements comprise lighting elements that are located beneath the translucent plate, the indicating elements being visible through the translucent plate when the corresponding lighting elements are energized. A plurality of operating elements are also provided where each operating element corresponds to a specific position on the control panel and the operating element is activated by a user pressing on, or otherwise touching, the respective position of each operating element.
In one implementation the operating elements are associated with indicating elements that indicate their position and at least some of the indicating elements comprise lighting elements that indicate the position of the operating elements. The lighting elements light up according to the operations that the user can perform at a given time.
In one implementation, a control panel for controlling the operation of at least a first hotplate and a second hotplate situated on a cooking appliance is provided, the control panel comprising a translucent plate having a top surface, and a plurality of operating elements with each operating element having associated lighting elements located below the top surface of the translucent plate, the location of the operating elements being identifiable on the top surface of the translucent plate only when the associated lighting elements are energized, the plurality of operating elements comprising a first hotplate selection switch, a second hotplate selection switch, and at least one control switch usable to select at least one hotplate operating parameter, the lighting elements controllable to be energized and/or de-energized so that only the operating elements associated with selecting and operating a particular hotplate are made visible on the top surface of the translucent plate while a user is in the process of selecting or otherwise altering an operating parameter of the particular hot plate.
In one implementation, a control panel for a cooking appliance having at least a first hotplate and a second hotplate is provided, the control panel comprising a translucent plate having a top surface, and a plurality of operating elements with each operating element having associated lighting elements located below the top surface of the translucent plate, the location of the operating elements being identifiable on the top surface of the translucent plate only when the associated lighting elements are energized, the plurality of operating elements comprising a first hotplate selection switch, a second hotplate selection switch, and at least one control switch usable to select at least one hotplate operating parameter, at a first moment all of the associated lighting elements being de-energized, at a second moment only the associated lighting elements of the first and second hotplate selection switches are energized to cause the location of the first and second hotplate selection switches to be identifiable on the top surface of the translucent plate, upon a user acting on the first hotplate selection switch the associated lighting elements of the second hotplate selection switch are temporarily de-energized and the associated lighting elements of the hotplate control switch or switches usable in connection with the first hotplate are energized to cause the location of such hotplate control switches to be identifiable on the top surface of the translucent plate.
In another implementation, a control panel for a cooking appliance having at least a first hotplate and a second hotplate is provided, the control panel comprising a translucent plate having a top surface, an on-off control switch operable from the top surface of the translucent plate, and a plurality of operating elements with each operating element having associated lighting elements located below the top surface of the translucent plate, the location of the operating elements being identifiable on the top surface of the translucent plate only when the associated lighting elements are energized, the plurality of operating elements comprising a first hotplate selection switch, a second hotplate selection switch, and at least one control switch usable to select at least one hotplate operating parameter, all of the associated lighting elements being de-energized when the on-off control switch has an “off” status, upon the on-off control switch initially assuming an “on” status after having had an “off” status, the associated lighting elements of the first and second hotplate selection switches are energized to cause the location of the first and second hotplate selection switches to be identifiable on the top surface of the translucent plate, upon a user acting on the first or second hotplate selection switch the associated lighting elements of the non-selected hotplate selection switch are de-energized temporarily and the associated lighting elements of the hotplate control switch or switches usable only in connection with the first hotplate are energized to cause the location of such hotplate control switch or switches to be identifiable on the top surface of the translucent plate.
An advantage of the present invention is that the control panel guides the user, showing him/her at each moment only what he/she needs and hiding the rest. As a result, in one implementation the indication field of the control panel of the cooking top does not have any indicator symbols printed on it, except for the initial on and off symbol.
These and other advantages and characteristics of the invention will be made evident according to the drawings and the detailed description thereof.
In addition, the operating elements are associated with indicating elements that indicate their position, and at least some of the indicating elements comprise lighting elements that indicate the position of the operating elements. The lighting elements are illuminated according to the operations that the user is able to perform at a given time.
In the embodiment of
In an alternative implementation, the control panel does not have any indicator symbols printed on it for the purpose of operating the cooking top. In such an embodiment, the on-off function is achieved by a user touching any portion of the top surface of the control panel.
In one implementation when the cooking top 100 is switched off, none of the operating elements are visible on the face of the control panel except for the on and off element 6. In one implementation the on-off element 6 is always visible by way of always being illuminated when power is supplied to the control panel, or by way of a printed symbol on or within the control panel. In one implementation, when the cooking top 100 is switched on, the on-off operating element 6 is illuminated and the control panel 20 changes to a “select” mode as shown, for example, in
When a hotplate is selected for the first time, the default power value can be, for example, the maximum value. In one implementation the maximum power value is 9 and is visible on the corresponding operating element, as shown in
Turning again to
In one implementation, upon the user selecting the timer switch 14, the lighting elements of switches 11 and 12 are illuminated, as shown in
In one implementation, a power off element 13 is presented on the face of the control panel when a hotplate has been selected, as shown, for example, in
The invention contemplates the possibility of including other operating elements that make it easier, for example, to go to the previous status of the control panel 20 without confirming changes, to confirm changes, to adjust the sound of the switch when it is pressed, etc.
In one implementation, a locking element 15 is provided on the control panel 20 as shown, for example in
The control panel 20 can be used for a cooking plate with a glass-ceramic cooking surface, glass-ceramic cooking being understood as a cooking system in which there is a plate of glass between the heat source and the receptacle to be heated, and which can be an electrical, induction or gas system. In a preferred embodiment, the control panel 20 is built into the cooking plate itself. The control panel 20 may also be used in a conventional gas cooking appliance.
As stated above, the control panel 20 of the cooking top 100 guides the user through the process for programming the hotplates, showing him/her at each moment only what he/she needs and hiding the rest. This prevents needless confusions in the programming process and even allows elderly people to use the cooking top 100 in a simple and intuitive way. In addition, illuminating only the operating elements that can be used at any given time, avoids the needless illumination of non-usable operating elements.
