  • Publication number: 20190053335
    Abstract: The present disclosure relates to a microwave heating apparatus and method of heating a load using microwaves. The microwave heating apparatus comprises a cavity dividable into at least two compartments, a first microwave generator and a first feeding port for feeding a first mode field in a first compartment of the cavity, a second microwave generator and a second feeding port for feeding a second mode field in a second compartment of the cavity. The first mode field and the second mode field provide complementary heating patterns in the cavity when the cavity is undivided. The present disclosure provides the flexibility of heating a load in a large cavity or heating a plurality of loads in smaller compartments of the cavity while still providing even heating in the cavity and in the compartments.

  • Patent number: 9332596
    Abstract: A microwave oven has an oven chamber, a door hinged to the chamber, and at least one door position switch. The switch provides a signal on door position to a central process unit of the oven. A door position switch assembly includes the switch mounted on the door and adjacent a sliding cover element that is adapted to protect the switch in an open configuration of the door and a first protruding element adapted to move the sliding cover element when the door is closed on the oven chamber in order to make the switch accessible. Additionally, a second protruding element may be included that is adapted to actuate the switch in its accessible configuration.

  • Patent number: 7501608
    Abstract: The present invention provides a microwave oven and a method of operating a microwave oven, which minimises user involvement when heating a food item to a desired target temperature. According to the invention, the initial temperature of the food item is measured prior to the heating process, and the required heating time is determined automatically based on the initial temperature, the target temperature, and the amount of food as entered by the user. In order to heat a food item to a desired target temperature, the user only needs to position a container for temperature measurement and enter the amount of food. In particular, the present invention is preferably adapted for heating of baby food, such as baby milk contained in a baby bottle, and in such case the target temperature is preferably preset to about 37° C.
