摘要： A microwave oven includes a tray holding unit which stably holds both a cooking tray and a tray guide at their original positions regardless of vibration and impact applied to the cooking tray and/or tray guide. The tray holding unit includes a base part, and elastic blade parts which are formed on both sides of a lower surface of the base part and extend downward from the lower surface while being inclined outward at an angle of inclination. A stop rail is horizontally formed along an inner surface of left and right sidewalls of a cooking cavity of the microwave oven, so as to stop top edges of the base part and allows the blade parts to press down on the cooking tray. Accordingly, the cooking tray and the tray guide are stably held down by the tray holding unit.

摘要： A microwave oven includes a main casing with a cooking chamber, a door for opening and closing the cooking chamber, and a magnetron in the main casing, for heating food within the cooking chamber. The microwave oven further includes a power supply part, a first door switch closed while the door is closed to supply electric power from the power supply part into the magnetron, a monitor switch connected in series to the first door switch, being operated in reverse relative to the opening and closing of the first door switch, and a control part determining that the first door switch is in trouble where the first door switch and the monitor switch are not operated in reverse to each other, and preventing the electric power from being supplied into the magnetron when the door is opened while the first door switch and the monitor switch are both closed. With this configuration, the number of necessary switches are decreased and the circuits' structure is simplified, and thereby, the cost of production can be lowered and the stability of circuits can be improved.

摘要： A non-directional frequency generator spark prevention apparatus including a plurality of electric connections connected with a direct current power source, i.e., brushes, and a commutator for converting direct current waveform inputted through the brushes into alternating current waveform by rotational movement thereof, and for outputting the alternating current waveform. A voltage pulse controlling part is connected between the brushes of the non-directional frequency generator, while having a resistor and a transistor which are connected in series with each other, and the transistor is operated synchronously with the rotation of the commutator of the non-directional frequency generator. By controlling the electric current to flow through the transistor during the brush-off period, a spark production during the brush-off period can be prevented. Further, by controlling the transistor to be turned off during a predetermined period between a predetermined time of the brush-off period to a predetermined time of the brush-on period, the electric current does not flow through the transistor at the beginning of the brush-on period, and accordingly, the spark production at the beginning of the brush-on period is prevented. A corresponding pulse generating part includes a photo-interrupter and a photo sensor, for generating a predetermined pulse waveform corresponding to the rotation of the commutator. Based on the pulse waveform, the transistor is operated, and accordingly, the transistor precisely synchronizes with the rotation of the commutator of the non-directional frequency generator.

摘要： A microwave oven has a cooking chamber in which a tray is provided for supporting food to be cooked. The tray is rotatable and can be raised and lowered. Cooking can be performed by microwaves and/or an electric resistance heater disposed in the cooking chamber. A sensor disposed in the cooking chamber detects a condition wherein food on the rising tray is at a height corresponding to that of the heater. In response to the sensing of such a condition the heater is turned off, a mechanism for raising the tray is also turned off, and a warning is emitted.

摘要： A microwave oven prevents an overcooking of small food portions. The oven includes a weight sensing device for sensing the weight of food to be cooked. If the sensed food weight is greater than a reference weight, then a cooking time is set, e.g., manually or automatically on the basis of a selected cooking mode and/or the sensed food weight. If the sensed food weight is less than the reference weight, then a maximum cooking time is automatically set which is the same, regardless of the amount by which the food weight is less than the reference weight. The cooking time cannot exceed that maximum time period, thereby ensuring that the food will not be overcooked.

摘要： The present invention relates to a structure of a Management Information Base (MIB) communicated between a Network Management System (NMS) and an agent of a Network Element (NE). Conventionally, an operator provides the MIB to the NMS and the NE agent before the communication. If the MIB is not provided before the communication, the NMS cannot know what data to be retrieved from the NE agent and thus cannot understand the MIB. In order to resolve this problem, the present invention suggests using the claimed structure of MIB for communicating between the NMS and the NE agent. According to the present invention, when a MIB of the NE agent is changed, the MIB of the NE agent is reflected to the NMS automatically, and not by an operator's action. Therefore, the network can be managed automatically.

摘要： Disclosed is a circuit and a method for driving a DC microwave oven. The circuit for driving a DC microwave oven according to the present invention includes: an inverting means to convert DC into AC by a driving pulse; a high voltage transformer to transform the AC from the inverting means, and supply the transformed AC to a magnetron; a pulse driving means to generate the driving pulse; and an over-current detecting means to detect an electric current which is supplied to the inverting means from a DC power source, and output an over-current detect signal if the detected current is determined as an over-current, so as to avoid the generation of the driving pulse by the pulse driving means. According to the present invention, the driving of the magnetron could be stopped when a malfunction of an interlock switch caused by an error or the over-current from the DC power source is detected, and circuit elements can be advantageously prevented from being damaged by the over-current.
