Abstract: A high-frequency heat cooking device in which high-frequency electric wave is introduced from a high-frequency oscillating power source into a heating chamber through a power supply opening provided on a ceiling wall of the heating chamber, comprising a semi-spherical reflective device or post being protruded from and integrally formed with a waveguide, on a ceiling face of the waveguide at a position immediately above the power supply opening constructed on the ceiling wall of the heating chamber and the semi-spherical dielectric being located oppositely to the power supply opening.

Abstract: A turntable for an electronic range comprises: a tray-supporting element which is provided with a plurality of arms radially arranged and having rollers at end portions thereof, a substantially triangular concave portion at its lower surface, and a through-hole at its central portion; and a coupling unit which is provided with a boss portion received in the through-hole of the tray-supporting element, a substantially triangular flange portion engaged with the concave portion of the tray-supporting element, and a shaft receiving sleeve for receiving a driving shaft of an electric motor, which shaft receiving sleeve is integrally formed in a lower portion of the coupling unit.

Abstract: A latch assembly for a cabinet door of a microwave range is provided with a pivotal hook member of the cabinet door, which member is engaged with a dog projection of a hook housing mounted in a door-opening frame of a main body of the microwave range. On a peripheral portion of a cooking cabinet contained in the main body is fixedly mounted a door-opening frame on which is pivotally mounted a hook-operating lever in a lower-end portion of which is slidably mounted one end of a hook-operating rod the other end of which is brought into contact with the pivotal hook member of the cabinet door, the hook-operating rod being normally biased at its retracted position by a spring means. An upper-end portion of the hook-operating lever is brought into contact with a push pin portion of a push button which is mounted in a control panel of the microwave range in a retractable manner.

Abstract: A high-frequency heat cooling device in which high-frequency electric wave is introduced from a high-frequency oscillating power source into a heating chamber through a power supply opening constructed in a ceiling wall of the heating chamber, via a waveguide, comprising a plurality of reflecting plates formed by cutting the ceiling wall located at an end of said waveguide and inclining the plates in a suitable angle while the same number of power supply openings as the number of the plates being provided.

Abstract: A defrosting circuit switch unit for an electronic range comprises: a frame of said unit, said frame being provided with a shaft; a defrosting circuit switch lever provided in a case in which a time switch is incorporated; a connecting rod having its lower end portion connected with a free end portion of said lever, said connecting rod being slidably moved up and down; a rotary plate rotatably mounted on said frame through said shaft and provided with a stopper extending in a projecting manner, said stopper being received in an elongated hole of an upper portion of said connecting rod, said rotary plate being integrally formed with a projection and a sector cam, said projection abutting on a leaf spring mounted on said frame; and a tension spring mounted between said rotary plate and said frame so as to resiliently biasing said rotary plate, said tension spring being engaged with said rotary plate through an engaging hole provided in said rotary plate.

Abstract: In an electronic range, an opening/closing operation of a range door thereof is manually conducted while switching operation of a power-supply circuit is conducted through a push-button type starting switch to make it possible that a control unit for the power-supply circuit is not energized when the range door is open, so that a control switch of the electronic range is completely prevented from being misused.

Abstract: A flame-rise stopping means for a kerosene stove, comprising an annular reticulate member having an inwardly directed flame at the lower end of the annular member and a holder plate fixed to the underside of the top plate of the stove and serving to removably hold the annular reticulated element above and opposite the chimney of the stove.
