Definitions

  • the invention relates to a microwave oven with devices for coupling the microwave energy into the cooking space, with a wave stirrer distributing the microwaves and with a turntable arranged in a recess in the cooking space base, which serves in the cooking mode for receiving food to be rotated.
  • microwave ovens With microwave ovens, it is necessary to ensure that the microwave energy is distributed as evenly as possible in the cooking space. This can be achieved by a wave stirrer, also called a wobler, which is rotatably arranged in the upper area of the cooking space behind a panel near the coupling point, or by a turntable provided in the cooking space floor, as a result of which the food is rotated during the operating time.
  • a wave stirrer also called a wobler
  • the devices known in practice generally only have one of the two prescribed aids for uniform energy distribution.
  • the invention has for its object to provide a microwave oven of the type mentioned in such a way that by using a wave stirrer and a turntable optimal conditions with regard to uniformity of the energy distribution in the cooking space can be created and can be used in the food carrier of different sizes and numbers without the Dimension of the turntable area to be limited and in which the operation in front of the turntable and shaft stirrer can be adapted to all different cooking conditions by the optional connectivity of the turntable.
  • the solution to this problem is achieved by a microwave oven with the features of claim 1. Further refinements of the invention result from claim 2.
  • the design according to the invention gives considerable advantages for the everyday operation of a microwave oven. By activating the shaft stirrer and the turntable at the same time, an optimal energy distribution in the cooking space can be achieved.
  • the turn-off option for the turntable and its flush integration in the floor of the cooking space means that the entire space in the cooking space can be used. Since the turntable can be switched on alternatively, intermittently or together with the shaft stirrer using a program switch, several useful operating modes can be selected.
  • the microwave oven (1) has a cooking chamber (2) in which, in a known manner, a shaft stirrer (3) is arranged in the upper area and a turntable (5) is arranged in the bottom (4).
  • the turntable (5) is driven by a drive motor (6) via a belt drive (7).
  • the drive motor (6) of the turntable (5) and the drive of the shaft stirrer (3) can be controlled by a program switch (8).
  • the turntable (5) is arranged in a recess in the base (4) formed by an expression (9). Its top forms a flush transition to the floor area (4). This avoids protruding edges or steps in the cooking space, which can be disruptive when food carriers are pushed in.
  • the operating mode of the microwave oven can be selected using the program switch (8). It is possible to switch on the shaft stirrer (3) or the turntable (5) on its own or together. Furthermore, it could also be advantageous to switch on the turntable (5) intermittently during cooking with the shaft stirrer (3) activated. If you want to use the entire bottom surface of the cooking space (2), the turntable (5) is switched off, so that the food or the food support can be inserted or inserted over the entire surface of the cooking space.
  • position sensors can be arranged in the cooking space, preferably in the base (4). These can then block the turntable (5) from being switched on in the control system.
