A microwave oven for heating of foodstuffs including an oven cavity (4) with an opening, a microwave unit for feeding microwaves to the oven cavity, an openable door adapted to close the opening and constituting one of the walls of the cavity, and a microwave seal (6) for reducing the leakage of microwave radiation from the oven cavity when the door is closed. The microwave seal has the form of a groove (12) which surrounds the opening and which is longitudinally divided into a first cavity (7) ...

A microwave oven has a main body including a cooking compartment, and a component compartment in which a heating component is installed. An outer casing encloses the main body. A fan is provided at the component compartment corresponding to the heating component, and blows outside air to cool the heating component. An air inflow part is formed on the outer casing adjacent to the fan and through which the air from the cooling fan flows. A partitioning wall of a round shape separates the cooking c...

The present invention relates to a microwave component with an at least partially enclosed cavity, such as a microwave filter, a waveguide or a horn antenna, comprising an outer support structure (A) and an electric layer (C) which is made of pulse-plated silver and which is arranged on the inside of the support structure and faces the cavity. The microwave component is distinguished in that it further comprises a first inner protective layer of chemically precipitated gold (D), said a protectiv...

A microwave generator comprises a magnetron having an anode and a cathode, oscillating by the current supplied to the anode, and generating a microwave, electric-field controlling means for controlling one of the frequency/phase and the amplitude of the microwave by varying the electric field, and magnetic-field varying means for stabilizing the other by varying the magnetic field.

A microwave detector for detecting faint detection target microwave signals is constructed from a heterodyne-type reception portion equipped with an antenna for picking up microwave signals, a local oscillator for repeatedly carrying out a sweep operation, and a mixer for frequency mixing the output from the antenna with the output from the local oscillator, wherein the heterodyne reception portion outputs detected wave signals based on the output from the mixer; a digital processing portion whi...

A microwave generator having a central electrode (14) which at the front end has a radiating element (22) and an external electrode (18) which coaxially surrounds the central electrode (14) along an axially extending resonator portion (16), wherein the two electrodes (14 and 18) are of a rotationally symmetrical configuration and define a spark gap (62) which sparks across when a high voltage is applied and radiates microwaves by way of the resonator portion (16) and the radiating element (22) o...

The superimposition of the microwave fields of an array (10) of microwave generators (11), with self-firing spark gaps (13) for the discharge of storage devices (43), which are charged up to a high voltage, results in an increase in field strength and a capacity for influencing the frequency spectrum of the emitted high-energy high-frequency field and the emission direction thereof.

A microwave oven including: a main casing forming a component compartment and a cooking compartment and formed with a component compartment through portion communicating with the component compartment; a fan assembly coupled to the main casing, and including an exhaling fan blowing air toward the component compartment through portion to cool the component compartment and a fan motor driving the exhaling fan; and a guide unit mounted to the component compartment through portion and guiding the ai...

Microwave oven including a case with a door, a cooking chamber in the case openable/closable with the door, and having a microwave applicable thereto, a first tray mounted in the cooking chamber to reciprocate therein, a second tray rotatably mounted on the first tray, and a link engaged with the motor and the first tray such that the first tray reciprocates within the cooking chamber, and further engaged with the motor and the second tray such that the second tray rotates with respect to the fi...

A microwave oven having a cooking chamber, at least one heat outlet provided in a sidewall of the cooking chamber, at least one heat inlet provided in the center of the sidewall of the cooking chamber, and a convection assembly. The convection assembly is disposed on an external side of the sidewall of the cooking chamber, and includes a fan, a heating element, and at least one guide bracket which guides heat from the heating element through the at least one heat outlet and into the cooking cham...
