Abstract

The present invention relates to a menu selection device in a microwave oven, which is constructed such that a single display device can be used in a state where it is divided into a menu guide unit and a menu selection unit. According to the present invention, a single display device 101 is divided into a menu guide unit 123 and a menu selection unit 127. Further, the menu guide unit 123 is constructed to perform only the display of menus, whereas the menu selection unit 127 is constructed in the form of a touch screen so that an arbitrary menu can be selected among the menus displayed on the menu guide unit 123. At this time, a desired menu can be selected by causing the respective menus and symbols corresponding to the menus to be displayed on the menu guide unit 123 and causing a symbol corresponding to the desired menu to be selected on the menu selection unit 127.
