Definitions

  • the invention relates to a system applied with an electronic card and embedded software which will provide the following features in the ovens; temperature, in-oven operation options (lower-upper heating, only lower heating, lower heating and fan, fan options etc.), cooking settings (semi-automatic, automatic cooking etc.), indicator settings (clock, sound level, brightness etc.), touch features on the display panel for indicators (temperature “ C, active modes and functions, icons).
  • the current oven controllers provide the touch feature on the oven display panel by means of the hardware design and embedded software. Although applications have been made in the world by new generation sensors, there is no application example with novel feature which corresponds to the mechanical rotary button.
  • the indicators (7-segment indicator etc.) used in the electronic cards in the prior art mostly cause height difference between the electronic card and usage area (for example panel surface). Namely, the button configuration in touch feature is located on the lower portion and the display is located on the upper portion (zero distance to the panel).
  • the string of the spring (M4) etc. elements (placing thereof on the card or combining thereof with the help of soldering) is an operation which is open to mistake and time consuming.
  • buttons that they can be influenced from each other. Namely, when touching action is performed on any button, another button may act as it was touched although it was not touched. Another example is that, before touching action is carried out, when the finger approaches for contact, the button or buttons may act as if the touching action is realized. In order to eliminate this condition, precise setting is very difficult. Also, since the determined threshold values are exceeded in required tests to be made in household appliances, there will be a problem (locking of the buttons under high frequency, not carrying out the functions).
