3236 results about "Microwave oven" patented technology

A microwave oven (also commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the outer 25–38 mm (1–1.5 inches) of a homogeneous, high water content food item.

Apparatus and method for transmitting and receiving data in microwave oven

The invention relates to an apparatus and method for data transmitting/receiving between a microwave oven and an information appliance PDA. The apparatus includes a wireless data transmitting/receiving unit for conducting wireless data communication with an external system including an information appliance; a data storage unit for storing transmitted/received data through the wireless data transmitting/receiving unit and/or downloaded data from Internet; a display unit for displaying transmitted data from the wireless data transmitting/receiving unit; a load drive unit for driving a magnetron and/or a heater; and Micom interfaced with the above elements, and interpreting the transmitted data from the wireless data transmitting/receiving unit and/or checking a state of the microwave oven, and controlling the wireless data transmitting/receiving unit to transmit the data on the state of the microwave oven to an information appliance. According to the invention, although the microwave oven does not include built-in networked communication equipment like a modem, it can interface with Internet through an information appliance, a PDA for example, which download data and transmits to the microwave oven. Thus, increase in price of the microwave oven with the modem is minimized and user interface is provided. Also, repair cost of the microwave oven can be minimized by checking the microwave based on the data on the internal state of the microwave being transmitted to the PDA.

Method for optimizing microwave oven and set meal cooked by microwave oven by utilizing near field communication (NFC)

The invention discloses a method for optimizing a microwave oven and a set meal cooked by the microwave oven by utilizing near field communication (NFC). The method comprises the steps of respectively putting food materials at the different positions of a cooking ware according to the different fire powers needed by the various food materials in the cookbook set meal; storing the fire power data corresponding to the cookbook set meal into an NFC label, and fixing the NFC label on the cooking ware; pressing an automatic cooking button of the microwave oven, and starting an NFC card reader arranged on the microwave oven to enter an automatic cooking mode; putting the prepared cooking ware into the microwave oven according to the specified direction; if the NFC card reader arranged on the microwave oven can continuously identify the NFC label, proving that the cooking ware is arranged in the microwave oven according to the correct direction; reading the cooking fire power and the cooking time data in the NFC label by using the NFC card reader, and sending the results into the microwave oven to enable the microwave oven to cook according to the cooling fire power and the cooking time. The NFC label comprises the data such as the cooking fire power and the cooking time for the set meal, so that the data is not manually input by a user, and the method is simple and fast.

Method and device for curing fiber-reinforced resin-based composite material component by utilizing microwaves

The invention relates to a method and a device for curing a fiber-reinforced resin-based composite material component by utilizing microwaves. The microwaves which are generated by a microwave source with linearly-adjustable power are guided into a resonant cavity, and the microwaves penetrate through and heat the composite material, so that the composite material can be quickly cured and formed. By adopting the advanced octagonal microwave-mode resonant cavity, the uniformity of an electromagnetic field inside the device can be realized; the interference of the reflection wave on the microwave source can be reduced by adopting an automatic impedance matching system, so that the optimal transmission of the microwave power can be realized. A vacuum pipe connector and a temperature sensor are arranged on the inner side wall of the octagonal multi-mode resonant cavity, a glass worktable is arranged inside the resonant cavity, and the rotation of a ball screw is controlled through a stepper motor to control the back-forth movement of the worktable. A choking groove is adopted to prevent the leakage of the microwave. By adopting the method and the device, the problems of the traditional autoclave forming method that the time for manufacturing the fiber-reinforced composite material is long, the energy consumption is high and the heat is non-uniform can be solved, the curing time can be saved, and the quality and performance of the composite material component can be improved.

System and method of interferentially varying electromagnetic near field patterns

A system for ablating tissue using interferential electromagnetic fields, comprises tumor shape information; radiation tip shape and position information; a mathematical model for computing first frequency and phase information, second frequency and phase information, and mixing information based on the tumor shape information and on the radiation tip shape and position information. The system further comprises a first generator mechanism for generating a first tone based on the first frequency information and on the first phase information; a second generator mechanism for generating a second tone based on the second frequency information and on the second phase information; a mixer for mixing the first and second tones based on the mixing information; and a radiation tip for generating an interferential electromagnetic field pattern based on the first and second tones. The radiation tip may include radiation coils affixed to the distal end of a conduction member. The conduction member may include a set of nesting conductors for transmitting current to the radiation coils within the radiation tip, the current being selected based on the interferential electromagnetic field pattern desired. Also, using interferential electromagnetic field patterning, non-medical and/or non-cell-destroying systems, e.g., a tissue warmer, a faster microwave oven, an effective security gateway, and/or a safer cellular telephone, may be created.
