Abstract: There is provided a highly safe steam oven capable of controlling the amount of steam generated appropriately. Water dripped from a water feeder to the inside of a cooking chamber is converted into steam by a heater in the cooking chamber. The thus generated steam in the cooking chamber is discharged through a steam channel which keeps the inside of the cooking chamber connected to the outside of the steam oven. The temperature of steam passing through the steam channel is measured by a steam temperature measuring device. The amount of water fed from the water feeder is controlled in response to the measured temperature.

Abstract: A normal position detecting mechanism for detecting a position of a functional component in a heating apparatus includes a drive member mounted on the functional component, a drive unit assembly mounted on the heating apparatus, and a switch for generating a detection signal. The driven unit assembly includes a switch actuating member, a bracket for supporting the switch actuating member, and a biasing member arranged between the mounting bracket and the switch. The biasing member applies a bias force for driving the switch actuating member against the direction for generating the detection signal. The drive member is positioned facing the switch actuating member when the functional component is in its normal position so that the drive member provides a force to move the switch against the biasing force to generate a detection signal.

Abstract: A turntable drive mechanism in a cooking oven. A driver unit is arranged outside a cooking chamber for rotationally driving a turntable, and a magnetic coupling is arranged between a revolving shaft of the turntable and another revolving shaft of the driver unit. The magnetic coupling is composed of a first coupling member attached to the revolving shaft of the driver unit and having magnets arranged so as to provide a surrounding of the revolving shaft with magnetic poles of alternately different polarities, and a second coupling member attached to the revolving shaft of the turntable and having magnets arranged so as to provide a surrounding of the revolving shaft with magnetic poles of alternately different polarities. The first and second coupling members face each other with a non-magnetic wall portion defining the cooking chamber being sandwiched therebetween.

Abstract: A drainage hole structure in a cooking oven of forced convection type, utilizing: a drain pipe arranged so that an upper end opening thereof is open to a bottom face portion of a heating chamber and a lower end opening thereof is open to the outside of the heating chamber; and an air suction pipe arranged so that one end opening thereof faces to the upper end opening of the drain pipe in close proximity thereto and the other end opening thereof is open to a middle portion in the heating chamber, wherein the one end opening of the air suction pipe is formed to be slightly larger than the upper end opening of the drain pipe, and in the upper end opening side of the drain pipe, a peripheral wall portion of the drain pipe positioned in an upstream side with respect to an airflow flowing along the bottom face portion of the heating chamber is extended so as to enter into the one end opening of the air suction pipe by only a short distance, while a peripheral wall portion of the drain pipe positioned in a downstrea

Abstract: Disclosed is a steam generating mechanism in a cooking oven equipped with a heater and a fan for blowing a hot air into a chamber of the oven, said steam generating mechanism further comprising: a water-supply receiver guide attached integrally to a fan guard which is detachably mounted in the front face side of said fan; and a water-supply unit for supplying water to the water-supply receiver guide when the need arises, wherein the water supplied into the water-supply receiver guide is guided toward the suction side of the fan, sucked by the fan together with the air inside the chamber, and dispersed toward the heater, so that the water may be heated by the heater to be formed into steam, which is then blown into the chamber of the oven.

Abstract: A heating apparatus of the present invention relates to a high speed oven having a turntable mechanism for heating food products by utilizing a combination of jet impingement of heated air (a jet impingement) and microwaves or either of them, the apparatus comprising a safety device and an exhaust device.

Abstract: A heating apparatus includes a central support axle positioned within a heating chamber of the heating apparatus. The heating apparatus provides both hot-air heating and micro-wave heating. A turntable has a central portion supported by the central support axle so that the turntable is rotated around the central support axle. A driving source is positioned at an upper side of the heating chamber for generating a rotating torque, and a connecting shaft for transmitting the rotating torque generated by the driving source to the turntable is provided in the heating chamber. The turntable has an entirely flat shaped section including a plane on which food products to be heated are mounted. A central portion of the flat shaped section is defined at a concave which is downwardly recessed into the plane and arranged to be fixed to and supported by the central support axis.
