摘要: A radio frequency (RF) heating and defrosting apparatus may include an electrode which, when supplied with RF signal energy, may responsively radiate electromagnetic energy into a cavity of the RF heating and defrosting apparatus. This radiated electromagnetic energy may cause a thermal increase of a load in the cavity. A capacitor may be formed from a portion of the electrode and a conductive plate disposed adjacent to the electrode. The conductive plate may be coupled to a ground reference structure. Dielectric material(s) having a low dielectric constant may be disposed directly between the electrode and the conductive plate.

摘要: Method of irradiating a load placed in a cavity by radiating UHF or microwave radiation into the cavity. The method includes setting transmission durations, by setting for each of a plurality of frequencies, a respective transmission duration, repeatedly causing energy to be transmitted into the cavity at the plurality of frequencies according to a duty cycle, wherein the duty cycle defines an allotted transmission time for each of the plurality of frequencies, and switching ON or OFF transmission of the energy at certain frequencies, so that over a plurality of repetitions of the duty cycle the energy is transmitted at each of the plurality of frequencies for the respective transmission duration.

摘要: A defrosting system includes an RF signal source, an electrode proximate to a cavity within which a load to be defrosted is positioned, and a transmission path between the RF signal source and the electrode. The system also includes power detection circuitry coupled to the transmission path and configured repeatedly to take forward and reflected RF power measurements along the transmission path. A system controller repeatedly determines, based on the forward and reflected RF power measurements, a calculated rate of change, and repeatedly compares the calculated rate of change to a threshold rate of change. When the calculated rate of change compares favorably with the threshold rate of change, the RF signal source continues to provide the RF signal to the electrode until a determination is made that the defrosting operation is completed, at which time the RF signal source ceases to provide the RF signal to the electrode.

摘要: An apparatus for irradiating a load with UHF or microwave radiation includes a cavity for accepting a load, at least one energy feed for transmitting energy into the cavity at a plurality of UHF or microwave frequencies to irradiate the load, and a controller. The controller sets transmission durations, by setting for each of a plurality of frequencies, a respective transmission duration, repeatedly causes energy to be transmitted into the cavity at the plurality of UHF or microwave frequencies according to a duty cycle, and switches ON or OFF transmission of the energy at different frequencies in different repetitions of the duty cycle, which defines an allotted transmission time for each of the plurality of UHF or microwave frequencies. Over a plurality of repetitions of the duty cycle the energy is transmitted at each of the plurality of frequencies for the respective transmission duration.

摘要: An apparatus for applying electromagnetic energy to an object in an energy application zone via at least one radiating element is disclosed. The apparatus may include at least one processor. The at least one processor may be configured to determine a value indicative of energy absorbable by the object at each of a plurality of frequencies and to cause the at least one radiating element to apply energy to the zone in at least a subset of the plurality of frequencies. Energy applied to the zone at each of the subset of frequencies may be a function of the absorbable energy value at each frequency.

摘要: A solid-state radio frequency (RF) microwave oven for an aircraft galley is dimensioned to fit the galley and includes within the oven cavity an array of RF modules disposed on the upper interior surface of the cavity. Each RF module includes one or more RF emitters programmable to heat meals placed within the oven cavity by emitting tunable RF signals. The RF modules may monitor the internal temperature and doneness of the food by detecting returned unabsorbed energy. An oven control module (OCM) may communicate with the aircraft galley network, selectively manage the activation and deactivation of RF modules depending on the food being cooked and its changing internal temperature, and tune emitted RF signals to avoid interference with aircraft communication systems. Compact heat sinks may be located within the rear of the oven cavity for the removal of excess energy from the oven.

摘要: A microwave heating device includes radiating portions that are adapted to radiate microwaves to the heating chamber and is operated according to operational configurations that differ in frequency and/or in phase shift. A learning procedure is executed in relation with a product positioned in the heating chamber. The learning procedure is executed by changing frequency and phase shift(s) to sequentially operate the radiating portions in a plurality of operational configurations, in such a way that, for each frequency, the radiating portions are operated in a number of operational configurations that differ in phase shift. An energy efficiency is calculated for each of the operational configurations and the obtained data are saved. A heating procedure is executed after the learning procedure. In the heating procedure, the radiating portions are operated according to at least one operational configuration that is selected on the basis of the data obtained in the learning procedure.
