Here, the sensor preferably includes a transducer to sense a physical parameter on the cook top of range. The transducer will generate an electrical signal representative of the physical parameter and apply the data to a processor. In response, the processor drives a digital display, which produces visual indications of these parameters. The processor provides communication between the sensor(s) and the remote receiver which drives some operations by the ventilator. For example, the receiving unit 62 controls the ventilator from signals for turning on, to adjusting the speed of the blowers. The sensor(s) and receiver(s) may both have a transmitter and receiver to enable communication through signals. This would be helpful when changing set points or detection points. 7. The combination appliance according to claim 1, wherein the control module comprises a user interface, wherein interface unit and/or the user interface of the control module, comprises a receiver unit adapted to receive voice commands. (65) The appliance 15 may also be equipped with a sound- or voice-activated system that in one embodiment lets the user speak to the appliance and state what controls and operations the user wants. This provides the user the ability to operate hands free, therefore, allowing the users to do something else with their hands. Alternatively, the appliance can be hooked up to a PC computer or a whole house computer system for operation and control. 8. The combination appliance according to claim 1, wherein the operation parameter of the extraction device is a power level of the fan or a rotational speed of the fan, and is adjustable by user settings. (72) As mentioned, another aspect of the present invention is to have nearly infinite fan speed adjustment levels. This can be done, for example, by having the user touch down on a glass resistance keypad until the speed required is reached. Once the speed is reached, the electronic control may reduce or completely cut off current/power to the blower(s)/fan(s). The keypad may have one or more keypad location(s) for operating the increase or decrease/on or off of the speed by the user. For example, three locations for independent operations can provide the user with better control. A display may show the user the speed level and may be used to assist in finding proper speeds, which then can be programmed in to the electronic control circuit for repeated operations later. Alternatively, the sensor 93c for controlling the fan 44 may be connected to fan regulator 48 as shown in FIG. 3. 9. The combination appliance according to claim 1, wherein the control module is coupled with at least one illumination device that comprises one or more light sources and is arranged in an area of the recess.

The combination appliance according to claim 9, wherein the control module is adapted to control a light parameter of each light source of the illumination device, said light parameter being on/off switching, light intensity and/or light color, as a function of time. Also mounted on the backing may be lighting 45 which preferably includes a control for the lighting 96. (63) Another aspect of the present invention is a multi-function display. For example, a clock may be on the electronic(s) display when not in use or when in use. See, e.g., item 112 in FIG. 8. It may also be changed to permit other programmable information to be displayed, such as, messages or computer information. This area may also have an LED night light included in the electronics such that the LED would come on when the room is dark. The use of an LED or a bulb of this type can save energy and space. 11. The combination appliance according to claim 10, wherein the operation parameter of the extraction device is indicated at the illumination device by changing said light parameter over time. (64) Another aspect of this invention is the ability to have "no switch" controls. Here, for example, the cook top backing 29 acts as the switch. For example, a user may touch the trim top surface in the front, top, or sides and this would operate the ventilator by moving it and turning on the blower. Alternatively, a user may touch the ventilator a number of times to move it up or down or to speed up or slow down the fan. The user may also touch the ventilator and hold for a longer time to which the blower would turn off or on. The user may turn a light on in the same manner. 12. The combination appliance according to claim 10, wherein the operation parameter of the cooking hob indicates changes of said light parameter over the time at the illumination device. The combination appliance according to claim 10, wherein the operation parameter of the cooking hob [is indicated by] changes of said light parameter at the illumination device.
