A domestic microwave oven is provided having an oven cavity, a water reservoir, a piping system coupling the reservoir and the oven cavity, and a pump for pumping a predetermined amount of water into the oven cavity. The pump is a mono-directional positive displacement pump and the piping system includes a by-pass coupled in parallel to the pump and an on/off electro valve configured to allow a drainage of the piping system when the pump is idle.

An electronic cigarette includes a main body and a microwave heating module disposed in the main body. The microwave heating module includes a shielding sleeve, a strip of cotton, and a microwave source. The strip of cotton is disposed in the shielding sleeve. The shielding sleeve is disposed above the microwave source. In a power-on state, the microwave source emits microwave. The microwave is released into the shielding sleeve to heat and atomize e-liquid adsorbed on the strip of cotton to produce vapor for user's inhaling.

A pulsed electromagnetic irradiation system for water treatment including raw water supply unit in fluid communication with a reaction vessel, a multimode cavity in which the reaction vessel is partially positioned. A magnetron generator is positioned adjacent the multimode cavity and is electromagnetically coupled with liquid within the reaction vessel. A stirring motor is positioned adjacent a bottom surface of multimode cavity and operatively coupled with the reaction vessel to stir the liquid within reaction vessel. A parabolic arm air cooled condenser is terminally connected to the reaction vessel to be in fluid communication with the reaction vessel. A gravity vacuum funnel, where the gravity vacuum funnel is in communication with a first air/water cooled condenser. The first air/water cooled condenser outputs fresh water to a fresh water storage unit.

A microwave kettle includes a main vessel having a pivotally attached lid, with an insert attached to an interior of the lid and extending into the main vessel. The insert is configured with a number of nucleation sites to facilitate boiling of a liquid within the vessel.

A system and method for continuously treating blowdown water derived from one or more boilers using a microwave reactor, a cooling system, and an ion exchange filter to remove insoluble solids, organic matter, bacteria, and other impurities. The recovered water is stored, treated with a corrosion inhibitor, an oxidizing biocide, a non-oxidizing biocide, and a scale inhibitor, before being recycled for reuse in the boiler system.

Embodiments herein include processing systems for food products and related methods. In an embodiment, the processing system includes a housing and a product conveyor. The housing defines a processing channel that includes an electromagnetic wave heating chamber. The electromagnetic wave heating chamber is at least partially filled with a fluid, such as a fluid. The conveyor mechanism can convey food products continuously along a conveyance path including a serpentine pathway that includes a plurality of hairpin corners where a direction of the conveyance path is reversed and a depth of the conveyance path is increased. The electromagnetic wave emitting apparatus emits electromagnetic energy into the pathway. The average pressure in the electromagnetic wave heating chamber changes along the conveyor mechanism. The orientation of products along the conveyance path varies minimally along at least portions of the conveyance path. Other embodiments are also included herein.

The present invention is directed to a fluid heating apparatus comprising a substantially thin and flat spiral-shaped, closed channel. The channel may be enclosed about by a conductive material which heats under inductive, electromagnetic forces. The apparatus is configured to conduct fluid through the channel, the fluid being heated in the channel. The apparatus may also comprises an induction coil disposed adjacent the spiral channel to induce heat in the spiral channel. The spiral channel defines an inlet and an outlet. The apparatus of the present invention is configured to be disposed in spatially small or confined environments and to provide on demand heating of a desired fluid.

An apparatus for heating includes an elongate body having an upper end and a lower end, a first end cap removably attached to the upper end of the elongate body, and a second end cap removably attached to the lower end of the elongate body. The elongate body comprises a first section having a fan and a second section. Additionally, the first end cap includes a plurality of apertures being spaced apart in a substantially equidistant configuration. The apparatus is useful for providing a source of heating for homes, buildings, or other structures.

An apparatus and method for cooking at least one egg with an eggshell The apparatus comprises a housing provided with a device for providing microwave radiation in a confined space in the housing and a holder located in the confined space. The holder is provided with at least one cavity adapted to the shape of the egg with the eggshell. The apparatus further comprises means to insert a liquid into the holder for filling the cavity with the liquid to at least partly surround the eggshell of the egg located in the cavity. The apparatus comprises also means to control the amount of liquid in the holder during a cooking process of the at least one egg, wherein: a first amount of liquid is inserted into the cavity before providing microwave radiation in the cavity, which first amount of liquid surrounds the eggshell of the egg located in the cavity; a second amount of liquid is gradually inserted into the cavity.

The disclosed heat cooker includes a control unit for controlling operation of the variable-type air supply opening. The control unit controls operation of the variable-type air supply opening so that an openness of the air supply opening becomes a predetermined target openness larger than 0% during heat cooking by the heater of the heating object, and upon an end of the heat cooking of the heating object, the control unit further controls operation of the variable-type air supply opening so that the openness of the air supply opening becomes larger than the target openness.
