The present invention provides a high frequency heating apparatus having a structure, which can be mounted/dismounted an air-exhausting grille without any tools. In this apparatus, an air-exhausting grille is arranged by that a fixing claw portion having a bent Z-shape, a fixing hooking portion having a concave notch, and a magnetic joint plate are arranged, whereas a main body located opposite to the air-exhausting grille is arranged by that a slit hole, a hooking flange, and a magnetic fixing plate are arranged. As a result, since the magnetic joint plate is absorbed with the magnetic fixing plate to be fixed with each other, the mounting/dismounting work capability of the air-exhausting grille can be improved without using the tool in a simple manner, and furthermore, a clean cooking appliance can be secured, while the cooking appliance can be readily cleaned.

High frequency heating apparatus

A high frequency heating apparatus is equipped with an oven hood fan, including a heating chamber for entering/deriving an article to be heated into/from the heating chamber, an electric power supplying apparatus for radiating electromagnetic waves into the heating chamber, a cooling fan for cooling the electric power supplying apparatus, another heat-cooking apparatus operated by gas or electric power, which is installed under an appliance main body, and a ventilation fan for sucking hot air from an air intake port, which is generated from the another heat-cooking apparatus, and for exhausting the sucked hot air. In the apparatus, wind which cools a heat generating unit of the electric power supplying apparatus by the cooling fan is joined onto an air intake path of the ventilation fan.

A high frequency heating apparatus equipped with the oven hood comprises a heating chamber, a power supply apparatus for controlling high frequency output power by way of a semiconductor element, ventilation, and illumination for illuminating an object to be heated by another heat-cooking apparatus. Since the high frequency output power is controlled in such a manner that an optimum heating output power is applied in a linear manner for a proper time period, the heating output power can be controlled in the linear manner and the high frequency heating apparatus can be largely reduced in weight. As a result, the highest-speed heat-cooking operation by receiving the maximum high frequency output power can be realized, and the optimum cooking performance can be realized. Both the installation performance of the appliance to the mounting wall plane and the safety performance achieved by stably fixing the appliance can also be largely improved.

High frequency heating apparatus equipped with oven hood

Provided is a burner apparatus comprising a cabinet, a combustion cylinder disposed in the cabinet, a top panel disposed above the combustion cylinder and provided with exhaust holes formed in the peripheral portion thereof, a flame-shielding member with the lower surface thereof opened, provided to a portion of the lower surface of the top panel facing the combustion cylinder, and discharge means provided to the flame-shielding member for horizontally discharging flames rising from the combustion cylinder and streaming into the flame-shielding member, thereby averting the problem of flames undesirably coming out of the cabinet.
