A microwave oven has a magnetron () which generates microwaves to heat a heating object, and a control unit () which controls the magnetron (). During heating operation in which the heating object is heated with microwaves generated from the magnetron (), the control unit () controls the magnetron () so as to suppress abnormal operations of the magnetron () in response to a status of power supply supplied from outside.

Microwave oven

A cooking heater () of the present invention includes a cooking heater body () which includes a heating chamber; a drawing body () which is configured to be allowed to be pulled out of the cooking heater body () and pushed into the cooking heater body (); a rotating tray () which is arranged inside the drawing body () and which is configured to be allowed to be mounted to the drawing body and removed from the drawing body; a rotating tray drive motor () which is provided in the cooking heater body (); and a rotation transmission mechanism () which, with the drawing body () being pushed into the cooking heater body (), transmits rotational force from the rotating tray drive motor () to the rotating tray () and, with the drawing body () being pulled out of the cooking heater body (), blocks the transmission of the rotational force to the rotating tray ().

Cooking heater

The invention provides a drawer type cooking device, wherein the mounting positions of roller-shaped shock absorbing membersandattached to a drawer bodyare either aligned with portions of the side wallsandof the heating chamberwhere fixing anglesof the slide railsare attached and thus having enhanced rigidity, or arranged close to a bottom wallof the heating chamber, so that when a biased operation force is applied to the door, the generation of a gap between a front side panel of the cooking device bodyand the inner side of the door is suppressed, and the occurrence of a microwave leakage through the gap caused by not stopping the generation of microwave until the operation of a latch is thereby prevented in advance.

Drawer type cooking device

A water level sensor () is provided in an auxiliary tank () whose bottom portion communicates to a bottom portion of a pot () for generating steam and which is opened to the atmosphere. When water in the pot () keeps boiling and the stop time of a pump () reaches a predetermined time (e.g., 60 sec.), the pump () is driven for a predetermined time (e.g., 6 sec.) to supply water to the pot (). This temporarily suppresses the boiling of water in the pot (), lowering a steam pressure in a space formed by an external circulation passage (), a heating chamber, and the pot (). The water level in the auxiliary tank () then returns to a normal one, making it possible to correctly detect the water level in the pot ().

Heating cooker

The invention provides a drawer type built-in cooking device, wherein an air outlet portionfor discharging the inside air containing heat and vapor generated during cooking of an object to be cooked has an air outlet ductcommunicated from an air outlet port areaformed on a side wall of the heating chamberto a lower side portion of a front wallof the cooking device body. The outlet air flow flowing through the air outlet ductis sent downward from an air outlet openingformed to a lower side portion of the front wallof the cooking device bodyand discharged to the exterior of the device. The present invention enables to eliminate the prior art air inlet and outlet duct structure disposed below the heating chamber, and therefore, the height of the heating chamber can be increased correspondingly. Further, the air outlet openingis hidden from the exterior without having to attach a louver since the opening is covered by a doorwhen the door is closed, so that the exterior design thereof is improved.

Built-in cooking device

A cooking device comprises a cooking device body comprising a heating chamber for heating an object; a fan, comprising a bladed wheel and a casing having the bladed wheel in rotatable manner, to discharge air in the heating chamber; and an exhaust duct comprising an exhaust guide plane to guide the air blown out by the fan to the outside of the cooking device body. The casing comprises an arc-shaped guide plane to guide an air flow generated by a rotation of the bladed wheel in a rotation direction of the bladed wheel, and an outlet port opened from a part of the arc-shaped guide plane to one side in a tangent direction of the arc-shaped guide plane. The rotation direction of the bladed wheel is a direction opposite to the opening direction of the outlet port, and turbulence is generated in the exhaust duct.

Cooking device

In a cooking device for cooking an object to be heated, a first operation section is provided to a lower portion of a door, and a second operation section is provided to an upper portion on a front face of a cooking device body so as to be exposed in spite of the door being opened or closed. Numeric keys for accepting a selection from a plurality of recipes stored in advance and start keys for accepting a start of heating are provided to the first and second operation sections redundantly. Therefore, in a case of when the door closes, the first and second operation sections can be used in parallel, allowing arrangement of many keys to have good operability.

A cooking device body having a heating chamber for heating an object; a fan for discharging air in the heating chamber; and an exhaust duct for guiding air blown off from said fan to the outside of the cooking device body are provided, an opening is provided at a wall of said exhaust duct, and the fan is constructed to have a motor disposed outside the exhaust duct, a first plate which has a central side attached to the motor and an outer edge side attached to the periphery of the opening, a bladed wheel which is attached to the output shaft of the motor and disposed in the exhaust duct, and a second plate which defines a cavity between said bladed wheel and the first plate.
