• the invention relates to a cooking device having a user interface comprising a touch sensitive slider allowing touch control.
• Control devices are used to set the operating parameters of the cooking devices by obtaining user data input.
• the touch-sensitive control area in a circular or linear slider structure is adapted to user interfaces as easy-to-use adjustment elements.
• the control area created by means of a capacitive sensor adapted to the glass panel allows the user to enter data with increasing or decreasing values according to the direction of use or to switch between different program modes.
• control area is defined with a strip in the illuminated display direction.
• parameters such as power level and time are adjusted, for example by dragging the finger slider over the control area, making increase in clockwise and decrease counterclockwise movements.
• EP2397769B1 discloses at least one of the selection tools is designed as a control unit, a touch-sensitive slider in the longitudinal direction, and is set to position the cursor at a position or direction on the display element based on finger movement or position, in the longitudinal direction of the slide and against finger touch of the user.
• the object of the invention is to simplify the user interface that includes touch control areas in cooking devices.
• the invention relates to a cooking device comprising at least one heating element activated by a control unit provided behind a panel; a touch-sensitive control area secured on the panel defining a user interface; a number of touch sensors provided in the control area and connected in a way that provides electrical signal transmission that adjusts the operating parameters of the control unit and the heating element, arranged in a row to support the panel from the bottom, and a slider in the form of a strip touch wherein the touch sensors adjacent to each other are configured to provide a pressing signal indicating the position of the finger upon a drag gesture on the touch area.
• the slider of the panel is arranged at least partly translucent and the oven further comprising an illumination element extending beneath the slider and arranged to illuminate adjacent a first and/or second side parts of the touch area upon the pressing signal.
• the slider is in the form of a transverse extension that define linear drag movement.
• the user can, among other things, set the heating element operating parameters with a simple linear movement.
• the slider is in the form of a radial form that define radial drag movement path.
• the user can, among other things, set the heating element operating parameters with a simple circular motion.
• the illumination element contains multiple LED elements in the form of a strip. LED elements provide low energy consumption and at the same time, each LED unit can be placed on a single electronic control card in a compact structure together with touch sensors.
• the light intensity of the illumination element is adjusted to a lower or higher value than the first and/or second side parts adjacent to the touching area of the finger in the slider. This allows the user interface to guide the user. For example, in the first and second parts of the illumination element, the light intensity is selected low according to the touch area, while the finger moves in the drag zone, it facilitates for the user to see the setting.
• a dial is located on the slider such that indicates an active zone equipped with touch sensors and arranged to allow light transmission from illumination element to the ambient.
• the dial as part of the user interface with visual guidance, can guide the user in which direction the increasing or decreasing value for various cooking parameters, for example the power of the heating element, and shows the operational limits of the slider.
• the dial can be screen printed on the panel, or it can be placed in a transparent window at the bottom of the panel so that it can be seen from the outside.
• the dial consists of a plurality of spaced vertical bar forms located in a transverse direction scanning the slider of the dial.
• the visual accessibility of the bar forms has been increased by extending in the direction perpendicular to the drag movement, allowing the user to recognize the slider on the panel.
• the panel is comprising an opaque mask covering the control area and a transparent window having an opening to form an illuminated line when the illumination element is activated at the dial at the slider. While the transparent window allows the illumination elements to appear as forming a light line in the slider, light penetration to other parts is prevented by the mask, which will disrupt the light line.
• the illumination element is configured to illuminate the part from a proximal first edge away from the touch area to the touch area. This situation visually communicates to the user by what amount the user has increased or decreased the setting during the drag movement, with only the line length, without any alphanumeric notification. Thus, the need to use an additional alphanumeric display is eliminated.
• the illumination element is configured such that illuminates the corresponding zone to each touch sensor activated by finger drag movement in moving the touch area in a tracking simultaneous order.
• the illumination element electronically associated with it is provided almost simultaneously to present a light signal in the control area, indicating this, with a very short delay.
• touch sensors include spring touch sensor or ITO layer touch detection. In this way, a touch sensor is obtained that is resistant to cooking conditions that can cause contamination by external factors such as temperature, oil, etc.
• a pressing area is provided on the control area adjacent to the slider and sends a predetermined command to the control unit when activated.
• the pressing area also allows input additional commands, such as confirmation or cancel commands, to be entered from the control area.
