The heating cooking chamber includes an air intake hole portion that causes the inside and the outside of the heating cooking chamber to be communicated with each other. The duct member (30) includes a main body portion (31) that guides air so that the air travels from a first direction (D1) to a second direction (D2) intersecting the first direction (D1), a suction port (32) through which the air is sucked into the main body portion (31), a blow-out port (33) from which the air is blown out toward the air intake hole portion, and a rectifying portion (35) that determines at least one of a blow-out direction or an airflow distribution of the air at the blow-out port (33) and guides the air to the air intake hole portion.

A cooking device is described. The cooking device includes a main body. The cooking device includes a ventilation apparatus that is located at a lower side of the main body, that is configured to suck air into the main body, and that is configured to discharge air from the main body. The ventilation apparatus includes a base that is connected to the lower side of the main body and that includes an introduction port. The ventilation apparatus includes a swirler that is configured to generate suction by rotating air around the introduction port of the base and that includes a plurality of wings. The ventilation apparatus includes a driving unit that is configured to rotate the swirler. The ventilation apparatus includes a swirler guide that is configured to cover an underside of the swirler and that is configured to guide a flow of air around a center of the swirler.

A combined apparatus for heating, cooking, grilling and defrosting of foods of various kinds, depending on the type of foods to be treated from time to time and the duration of the foods treatment foreseen by each user of the same apparatus, where each hot treatment of foods may be effected either by heating or by microwaves only, or by heating and microwaves combined to each other. There are described in detail all the technical characteristics of the apparatus and the relative control circuits either for heating or for generating the microwaves. Advantages include use of a sole and single apparatus for hot treating the foods for providing for the heating, the cooking, the grilling and the defrosting of the same foods, instead of employing as it happens hitherto of single separated apparatuses for performing the same functions.

A microwave oven has a cooking cavity and an electrical chamber, with a magnetron, a frequency converter assembly and a cooling fan arranged in the electrical chamber. The frequency converter assembly has a mounting support mounted on a bottom plate of the microwave oven, a mounting base obliquely mounted on the mounting support, a frequency converter circuit board mounted on the mounting base and obliquely arranged relative to the bottom plate of the microwave oven, and an air guide cover covering over the frequency converter circuit board for guiding cool air blown by the cooling fan to the frequency converter circuit board. The microwave oven can not only solve the problem that the mounting space for frequency converter circuit boards is not sufficient, but also effectively control the temperature rise of the frequency converter circuit boards.

The invention relates to a microwave oven for material to be heated, in particular food material (40). The microwave oven (10) has an oven housing (12), to the housing cover (14) of which a number of microwave radiation sources (18) is coupled by means of microwave coupling elements (16). The microwave coupling elements (16) protrude from the housing cover (14) and are distributed in the peripheral direction. At least one material holding device (22) for the material (40) is provided in the oven housing (12), which material holding device can be rotated about a central axis (26) by means of a drive device (24). The at least one material holding device (40) is formed by a rotary plate (28) for holding the material (40) in a defined, positionally accurate manner.

An apparatus for annealing semiconductor integrated circuit wafers comprises a microwave energy source and a reactor housing. The microwave energy source is configured to generate microwave radiation having a first wavelength. The reactor housing is configured to receive a plurality of semiconductor integrated circuit wafers simultaneously. The reactor housing includes a top wall, a bottom wall, a left side wall, a right side wall, a front wall, and a back wall connected to one another to form a box-shaped internal chamber. Each wall is electrically connected to electrical ground and is water cooled. The walls of the internal chamber are spaced apart such that the microwave radiation forms a single mode within the internal chamber.

An oven includes a cooking chamber configured to receive a food product and an RF heating system configured to provide RF energy into the cooking chamber using solid state electronic components. The solid state electronic components include power amplifier electronics configured to provide a signal into the cooking chamber via a launcher assembly operably coupled to the cooking chamber via a waveguide assembly. An isolation assembly is provided between the launcher assembly and the power amplifier electronics. The power amplifier electronics are controlled at least in part based on an efficiency parameter determined from a forward power value and a reflected power value that are each measured after the isolation assembly.

An oven may include an oven body having at least sides and a housing cover, a cooking chamber disposed within the oven body and being configured to receive a food product, an RF heating system configured to provide RF energy into the cooking chamber using solid state electronic components to heat the food product, and an internal air cooling system configured to move air through the oven body to cool the solid state electronic components. The solid state electronic components include power amplifier electronics and control electronics configured to control operation of the power amplifier electronics. The power amplifier electronics are at least partially covered by an internal electronics cover. A first insulating member is applied to a bottom surface of at least one of the housing cover or the internal electronics cover to inhibit condensation above the solid state electronic components.

An air circulation system includes an inlet filter support structure, a first side filter and a second side filter. The air circulation system is for an oven that has a cooking chamber configured to receive a food product and a radio frequency (RF) heating system configured to provide RF energy into the cooking chamber using solid state electronic components. The air circulation system is configured to provide air for cooling the solid state electronic components. The inlet filter support structure enables cooling air for cooling the solid state electronic components to be drawn therein prior to circulation by a cooling fan. The first side filter is supported by the inlet filter support structure. The first side filter is disposed below one of the sidewalls and disposed at an angle relative to the one of the sidewalls. The second side filter is supported by the inlet filter support structure. The second side filter is disposed below an opposing one of the sidewalls and disposed at the angle relative to the opposing one of the sidewalls.

An oven and a method for controlling an oven are provided. The oven includes a case; a cooking chamber formed inside of the case; and a door installed at one side of the case so as to open and close the cooking chamber. The door includes an outer plate forming an exterior thereof; an inner plate spaced a predetermined distance apart from the outer plate and in contact with the cooking chamber, and a door display disposed between the outer plate and the inner plate so as to display predetermined information on the outer plate.
