Abstract: In a microwave heating apparatus, an electricity feeding port constituting a port of radiating a microwave is set to a ceiling wall of a heating chamber, a magnetron is arranged on a side of an outer side face of the heating chamber by directing an antenna for oscillating the microwave to a side of the heating chamber, and a wave guide for guiding the microwave oscillated from the magnetron to the electricity feeding port is formed in an L-like shape including a side wave guide extended upwardly from a surrounding of the antenna along the outer side face of the heating chamber and an upper wave guide extended from an upper end of the side wave guide to the electricity feeding port along an outer face of the ceiling wall.

Abstract: An inner box for a cooker is provided including a front plate having an opening portion and an inner box main body bonded to a peripheral edge of the opening portion comprising a first fold-to-bend portion constituted by folding to bend an end portion thereof to invert to be brought into close contact therewith and a second fold-to-bend portion constituted by inverting a portion on a side of the end portion of the first fold-to-bend portion with a predetermined clearance therebetween and a flange portion inserted into the clearance between the first fold-to-bend portion and the second fold-to-bend portion, and wherein the bonding portions of the front plate and the inner box main body are constituted by a structure of inserting the flange portion into the clearance to be calked to bond therewith.

Abstract: A heating cooker (100) for heating to process an object placed on a mounting base of a heating chamber (51) including at least a single piece of a rod-like heater arranged along a face member forming the heating chamber (51) and a heat shielding member provided along a longitudinal direction of the rod-like heater between the rod-like heater and the face member (53a) on an outer side of the heating chamber (51).

Abstract: It is a problem of the invention to provide a microwave heating apparatus capable of realizing small-sized formation of the apparatus while preventing occurrence of a nonuniformity in heating caused by a deviation of a position of mounting an electricity feeding port.

Abstract: A problem of the invention is to provide a heating cooker capable of producing a uniform baking mark at a total of an object at inexpensive cost by a single piece of a rod-like heater in a heating cooker interposing a face member between the object and the rod-like heater. A heating cooker (100) for heating to process an object placed on a mounting base of a heating chamber (51) including at least a single piece of a rod-like heater arranged along a face member forming the heating chamber (51) and a heat shielding member provided along a longitudinal direction of the rod-like heater between the rod-like heater and the face member (53a) on an outer side of the heating chamber (51).

Abstract: An inner box for a cooker including a front plate 13 having an opening portion 11 and an inner box main body 23 bonded to a peripheral edge of the opening portion 11 for cooking by irradiating a high frequency wave into the inner box main body 23, wherein at least either one of bonding portions 28 of the front plate 13 and the inner box main body 23 is formed with a first fold-to-bend portion 25 constituted by folding to bend an end portion thereof to invert to be brought into close contact there with and a second fold-to-bend portion 27 constituted by inverting a portion on a side of the end portion of the first fold-to-bend portion 25 with a predetermined clearance there between, other of the bonding portions 28 of the front plate 13 and the inner box main body 23 is formed with a flange portion 33 inserted into the clearance between the first fold-to-bend portion 25 and the second fold-to-bend portion 27 and the bonding portions of the front plate 13 and the inner box main body 23 are constituted by a stru

Abstract: A microwave heating apparatus includes a magnetron (6) mounted on a top surface of a wave guide (7). A bottom surface of wave guide (7) is inclined towards the bottom of the wave guide opening. A metal plate (9) is provided with a predetermined clearance above the bottom surface of wave guide (7). The microwaves are irradiated from an antenna (10) of magnetron (6) and travel along the bottom surface of wave guide (7). The microwaves are guided to an opening (8) under regulation by a metal plate (9) dispersion, and thus the microwaves reach the opening without suffering from the loss of energy. An object of heating (1) is irradiated directly by the microwaves with an improved heating efficiency.
