Definitions
- the invention relates to a control device for an oven, in particular an oven with a rotary control element provided on a control panel.
- a front panel is usually located on the body of domestic ovens, which provides a cooking chamber.
- There is a control panel or adjustment buttons on the front panel where the operation parameters of the oven are entered.
- the temperature setting is made with the help of a mechanical thermostat
- the working configuration of the resistances is made with the help of a program switch, especially a mechanical switch.
- Both the thermostat and the switch are controlled by a shaft extending vertically towards the front panel.
- the buttons placed on the front panel engage the spindle and enable the user to adjust the oven function and temperature separately by turning each button.
- EP2612076 relates to an operating device for a household appliance having only one operating element and a corresponding operating mode of operation and a display that can be rotated in certain stages.
- the stages are characterized by the setting of the stages of the operating element and the fact that there is only one operating unit adjacent to the operating element with touch-sensitive operating areas, in which the operating parameters are associated with the operating mode selected with the operating element.
- the invention further describes the operating method of the operating device for a household appliance and a household appliance comprising the corresponding operating device.
- the aim of the invention is to provide a simple adjustment of oven operating parameters with an oven with a single button control panel.
- the invention includes a cavity delimiting a cooking chamber; an enclosure that encloses the cavity in a heat-insulating manner; a door hinged on the housing and openly closing the cavity; a control panel arranged on the housing such that it extends from a lower edge above the door to which it is adjacent; It relates to an oven configured to activate at least one electrical heating element in a selected cooking mode for a predetermined time in the cavity to which it is connected and comprising a controller mounted in the housing behind the control panel. Also in the oven, the control panel is made of a single perforated sheet metal structure and includes a single rotary adjustment knob that is connected to the controller through a single hole, accessible from the outside, to set the operating mode.
- the controller may include a circuit board comprising electronic components and a processor, and preferably auxiliary mechanical or electromechanical motion transmission elements.
- the single perforated solid sheet metal effectively protects the controller from oil-containing vapors in case of opening the cover of the control panel provided on the door or if there is an exhaust opening on the door.
- the single rotary adjustment knob passing through a single hole allows the user to adjust both the cooking mode and the inside cavity temperature of the oven by activating the electric heating element for the specified temperature for a while with just a rotating movement.
- the single rotary adjustment knob comprises an adjustment shaft extending from one end to the controller and a rotary cap that covers the single hole by removably passing to the adjustment shaft from the other end.
- the swivel cover covers the single hole on the control panel, reducing the passage of steam.
- a sealing gasket can also be located under the rotating cover, surrounding the adjusting shaft and covering the single hole.
- the cover is in a hollow cylindrical form and includes a push button in the middle, which is provided in connection with the controller to provide an electrical signal.
- the push button has a functional function in the controller and can be used, for example, for confirmation after selecting a particular cooking mode. For this, simply pressing the push button on the cover triggers the associated switch and transmits an electrical signal to the controller that the push button has been pressed.
- the push button can be either a mechanical button structure or a touch sensor.
- a push button is realized with a capacitive sensor whose borders are drawn with a graphical user interface on a screen placed on the cover.
- a preferred embodiment of the invention includes an electronic indicator provided in the middle of the cover and connected in a way that transmits an electrical signal to the controller
- the electronic display is in the form of a TFT or similar flat display, connected by transmitting an electrical signal to the electronic control unit.
- the controller includes a thermostat connected to the electrical heating element so that it adjusts the cavity interior temperature in accordance with a selected set temperature by turning a single rotary adjustment knob.
- the thermostat can be a mechanical thermostat or it can be operated digitally by measuring the active temperature via a temperature sensor in the cavity with the help of a processor in the controller and operating the electrical heating element according to the expected temperature.
- the cavity includes an auxiliary electric heating element provided opposite to the electric heating element, and the controller is configured to selectively activate the electric heating elements according to the selected cooking mode by turning a single rotary adjustment knob.
- the controller gradually adjusts the cavity to a maximum temperature setting at a predetermined rotation angle and is configured to operate only the electrical heating element at the top of the cavity in a grill mode when the rotation angle is exceeded.
- a single control knob in one direction, both the operating temperature of the oven can be adjusted and the grill mode can be changed.
- both the top grill and the fan can be engaged.
- a touchscreen TFT display may be located on the oven's single control button. In this case, the functions can be set on the screen individually or on a function basis. The temperature is adjusted by turning a single control knob.
- a single rotary adjustment knob is provided in the geometric center of the control panel.
- the visibility of a single button on the solid sheet increases thanks to the non-perforated sections extending on both sides of the control panel.
- the single hole may also be aligned closer to one side of the sheet than the other.
- the single rotary adjustment knob is in circular form, which is aligned from one end to the lower edge and from the opposite end adjacent to an upper edge that runs parallel and opposite to the lower edge.
- the circular form extends close to two mutually parallel edges, making it possible to use a wide and ergonomic single button. Such a button provides sufficient space for mounting a screen displaying a user interface.
- Figure 1 is a front view of a representative embodiment of a domestic oven, the subject of the invention, with a single rotary knob.
- Figure 2 is a front view of a control panel provided with a single rotary knob with an LED element in a representative embodiment of the oven of the invention.
- Figure 3 is a front view of a control panel provided with a single rotary knob with a push button in a representative embodiment of the furnace of the invention.
- FIG. 1 shows a representative embodiment of a household oven from the front.
- the furnace comprises a cavity (13) provided with heat insulation on a prismatic housing (10).
- the cavity 13 is made of metal material and delimits a cooking chamber.
- a door (11) in the form of a flat panel covers the cavity (13) from its open mouth.
- the door 11 is connected to the housing 10 at a lower edge by a hinge (not shown).
- An electrical heating element (18) and an auxiliary electrical heating element (19) in resistance structure are mounted parallel and adjacent to a lower and upper wall of the cavity (13).
