  • Patent number: 6943321
    Abstract: At least two blowers are controlled with baffles to create circulating zones of airflow which circulate in a substantially horizontal plane within a convection oven cavity. This airflow minimizes the potential for airflow paths to be broken up or blocked by the configuration of objects placed in the oven. The substantially horizontal airflow reduces the non-uniformity of air temperature distribution within the oven cavity. The blowers may be controlled to rotate either simultaneously or alternately, depending on the selected mode of operation. The blowers and associated heating elements are controlled to operate in various cooking modes by the controller in response to a mode selector input.

    Abstract: A microwave cooking appliance includes an oven cavity, a magnetron and a load sensing system. The load sensing system is used to detects the presence of a load in the oven cavity by introducing a high frequency energy burst into the oven cavity, with the energy burst being reflected back. A controller, based on a time period between emitted and reflected signals, determines whether a load is present in the oven cavity. If no load is present, operation of the magnetron is terminated. Preferably, the high frequency energy burst is an ultrasonic acoustic frequency energy burst in a range between approximately 10 kHz and 100 kHz.

    Abstract: Cooking information (CI) concerning different dishes is preliminarily registered as a standard in a mask ROM (11A) or the like of a microwave oven (1), to enable automatic cooking of a variety of dishes for every user. In practice, however, the dishes which each user cooks by a microwave oven is limited to a few of them. Then, the user selects and registers a standard recipe name (HN) of only his/her favorite dish in the mask ROM into a favorite menu in a non-volatile memory (11B). In order to execute cooking of a desired dish registered in the favorite menu, the standard recipe name of the desired dish is read not from the mask ROM but from the non-volatile memory and displayed on an LCD panel (13), so that the user needs only perform an operation to instruct start of heating through an input unit (15).

  • Patent number: 6353214
    Abstract: The present invention relates to an automatic cooking of a microwave oven, in particular to an automatic cooking compensation apparatus of a microwave oven and a method thereof which is capable of solving a port number restriction problem of a microcomputer when data compensation corresponding to automatic cooking time is performed. The present invention can have data variable port as same as line number of a key matrix by using the data variable port for the cooking time compensation in conjunction with key input ports, accordingly the cooking data can be compensated as same as the number of line. In other words, data variable value inputs from four˜five up to eight are possible within the range permitted by the key matrix, accordingly the present invention is capable of varying all the automatic cooking data set in advance with low material expense and a simple hardware construction.

    Abstract: A microwave heating apparatus operates in either a first mode or a second mode, that allow different amounts of electric power to be supplied to a load and a control circuit for driving and controlling the load. The voltage applied to a primary coil of a transformer is lower in the second mode than in the first mode. In another apparatus, no electric power is supplied to a control circuit for driving and controlling a heating member and other circuits when the apparatus is in a standby state. However, when the user operates an operation member for opening the door of a heating chamber, electric power is supplied.

    Abstract: In a microwave oven, a turn table rotates once in a period TX. During one rotation of turn table, a control circuit usually detects six pulse signals. Control circuit detects a weight of food placed on turn table based on detected intervals TA, TB, and TC of pulse signals. Note that, if six pulse signals are not detected during one rotation of turn table, the control circuit retries detection of the pulse signals and detects the weight of food placed on turn table based on TA, TB, and TC for a subsequent rotation of turn table.
