The present invention is a microwave heating device and has a microwave guide tube, two microwave transmitting modules, and a transmission module. The microwave guide tube forms a wave travelling path and has at least one conveying opening pair and at least one waveguide plate pair. The at least one conveying opening pair has two conveying openings respectively disposed on two opposite walls of the microwave guide tube along a conveying direction. The at least one waveguide plate pair is disposed in the microwave guide tube and has two waveguide plates parallel with the wave travelling path. The two microwave transmitting modules are disposed on two opposite ends of the microwave guide tube. The transmission module extends through the at least one conveying opening pair along the conveying direction.

Embodiments disclosed herein include a housing for a source assembly. In an embodiment, the housing comprises a conductive body with a first surface and a second surface opposite from the first surface, and a plurality of openings through a thickness of the conductive body between the first surface and the second surface. In an embodiment, the housing further comprises a channel into the first surface of the conductive body, and a cover over the channel. In an embodiment, a first stem over the cover extends away from the first surface, and a second stem over the cover extends away from the first surface. In an embodiment, the first stem and the second stem open into the channel.

A cooking appliance includes a body having an interior to receive product to be cooked, the body having an opening via which the product can be moved relative to the interior; a pilot mounted within the body; and a door attached to the body to close the opening. The door includes a first latch mounted to the door and a second latch mounted to the door and independently reciprocable relative to the first latch between a first position and a second position, wherein the second latch is urged to move towards the second position such that, as the door is moved to close the opening, the second latch is received within the body and is deflected towards the first position by the pilot until a portion of the second latch clears the pilot and is urged to move towards the second position to come to rest behind the pilot.

Provided is a microwave treatment apparatus that can properly treat a treatment target using microwaves. The apparatus includes: a vessel 10 in which a treatment target 2 is arranged; a microwave irradiating unit 20 that irradiates an internal portion of the vessel 10 with microwaves; and heat generating member 30 that is provided inside the vessel 10 along the treatment target 2, generates heat by absorbing part of microwaves used for irradiation by the microwave irradiating unit 20, and transmits part of the microwaves. The microwave irradiating unit 20 irradiates a portion in which the heat generating member 30 is provided with microwaves, thereby heating the treatment target 2 from the outside through heat generation at the heat generating member 30, and directly heating the treatment target 2 with microwaves transmitted through the heat generating member 30.

A microwave heating appliance includes a housing having interior walls with interior surfaces defining a cooking chamber for heating food, a microwave heating source configured to generate microwave radiation for heating the food, and a rapid heating plate disposed in the cooking chamber. The rapid heating plate includes a substrate having a hybrid coating disposed on thereon, with the hybrid coating configured to generate heat upon application of a magnetic field and upon absorption of the microwave radiation from the microwave heating source. The hybrid coating includes ferromagnetic nanowires and ferritic carbon nanotubes dispersed in a polymer to generate heat for transferring to food placed on the rapid heating plate in the cooking chamber.

Provided are a substrate treating apparatus and a substrate treating method. The substrate treating apparatus includes: a chamber for providing a processing space; a substrate support unit provided in the processing space to support a substrate and rotate the substrate; a liquid supply unit including a chemical liquid discharge nozzle that discharges a chemical liquid to the substrate supported by the substrate support unit; and a microwave applying member for emitting microwaves to the substrate.

A cooking apparatus (1) comprises a base (7) comprising a lower heater (2) defining a bottom cooking surface (4) where a foodstuff (F) to be cooked can be positioned; a cover (8) closable onto the base (7) and comprising an upper heater (3) defining a top cooking surface (5) and a lifting system (16) for moving the upper heater to and from the lower heater when the cover is closed onto the base; a database (103) storing a plurality of selectable cooking programs each including one or more cooking phases each associated with corresponding cooking parameters including a temperature of the upper heater and a distance (d) of the top cooking surface from the bottom cooking surface; and a controller (18) configured to control the operations of the lifting system and the upper heater based on the cooking parameters of a selected program.

A food heating device includes a placement unit and a heating unit. The placement unit includes a housing and a placement board, wherein the placement board is disposed in the housing and is for placing a food item. The heating unit includes a water injection element and a microwave element, wherein the water injection element connects to the housing and is communication with an internal space of the housing, and the microwave element connects to the housing. The microwave element is for heating by microwave the water injected into the internal space of the housing through the water injection element and producing steam therefrom.

A method for heating or cooking a frozen food product with a susceptor in a solid state microwave oven includes placing the frozen food product with a susceptor into a microwave oven, heating the food product at a first heating step at a low absorption frequency, and heating the food product at a second heating step at a high absorption frequency.
