Abstract: A microwave oven includes a waveguide having an E-bend structure with multiple openings disposed on a lateral face of a heating chamber that allow the waveguide to communicate with the heating chamber. The waveguide has a first section for propagating a microwave from a magnetron toward the heating chamber, and a second section having a wide plane that abuts an outer wall of the heating chamber. The openings include at least one circularly-polarized-wave opening for generating a circularly polarized wave. A cross section of the first section orthogonally intersects a tube axis of the first section projects virtually along the tube axis of first section and onto a lateral face of the heating chamber, and the circularly-polarized-wave opening is configured such that its center is located outside the resultant projected region.

Abstract: Microwave oven (20) includes waveguide (3) having an E-bend structure, and multiple openings (4a, 4b). Waveguide (3) has first section (3a) for propagating a microwave from magnetron (2) toward heating chamber (1), and second section (3b) of which wide plane abuts on the outer wall of heating chamber (1). Multiple openings (4a, 4b) are disposed on a lateral face of heating chamber (1). Openings (4a, 4b) allow waveguide (3) to communicate with heating chamber (1), and include at least one circularly-polarized-wave opening (4a) for generating a circularly polarized wave. A cross section of first section (3a) orthogonally intersecting tube axis (7a) of first section (3a) is projected virtually along tube axis (7a) of first section (3a) onto a lateral face of heating chamber (1), and circularly-polarized-wave opening (4a) is formed such that its center is located outside the resultant projected region defined by this projection.

Abstract: A high-frequency cooking device includes: a heating chamber; a high-frequency generating device; a heating chamber opening portion; a door configured to cover the heating chamber opening portion so as to open and close; a choke portion provided on a peripheral edge portion of the door; and a choke cover which is formed by a resin and which is provided on the door in a position between the choke portion and a peripheral wall portion of the heating chamber opening portion. A ripple is formed on a tip of the choke cover which opposes the choke portion. The ripple seals a portion between the choke portion and the choke cover.

Abstract: A high-frequency heating device includes: a heating chamber configured to heat a food; a high-frequency generating unit configured to supply high frequency waves to the heating chamber; a driving power supply configured to drive the high-frequency generating unit; a cooling fan configured to cool the high-frequency generating unit and the driving power supply; an air guide serving as a blast guide of the cooling fan; and a noise filter configured to suppress a noise generated from the high-frequency generating unit and the driving power supply. The noise filter is attached on a cooling fan side of the air guide. A plurality of cooling holes are formed on a partition wall between a component mounting surface of a noise filter substrate and the air guide.

Abstract: To provide a high-frequency heating device of which reduction of weight and cost can be achieved, while a leakage of high-frequency waves is prevented.

Abstract: The object of the invention is to provide a high-frequency heating apparatus which has simple configuration, in which leakage into the apparatus from a water tank is prevented without large-sizing the apparatus, which is not influenced by heat from a heating chamber and which is sanitary and provides ease of use. To achieve the object, the high-frequency heating apparatus 100 provided with a high frequency generator that supplies a high frequency to the heating chamber for housing an object to be heated and a steam generator that generates steam in the heating chamber for supplying at least either a high frequency or steam to the heating chamber and heating the object to be heated is provided and the water tank for supplying water to the steam generator is arranged in any position on the outside face of the high-frequency heating apparatus 100 so that the water tank can be detached.

Abstract: A heating and cooking apparatus has a kneading trough detachably installed in a heating chamber of the apparatus and provided with a handle for easy carrying for a user. Since both the kneading trough and a portion to be engaged with the kneading trough in the heating chamber are formed square, the force in the rotating direction during the operation can be positively received by the corners, thereby enhancing the strength of the apparatus, without rattlings or wearing-out or disengagement of the engaging portion therebetween.
