A cooking device according to the present disclosure comprises: a heating chamber configured to accommodate an object-to-be-heated; a circulation fan configured to suck air in the heating chamber and blow the sucked air into the heating chamber; a heating chamber internal flow path forming unit disposed inside the heating chamber and configured to define the flow rate and the blowing direction of the air blown into the heating chamber by the circulation fan; and an internal temperature sensor disposed in a circulation path of the air and provided in a region apart from the heating chamber internal flow path forming unit by a predetermined distance, the circulation path being formed inside the heating chamber by the heating chamber internal flow path forming unit.

Cooking device

Cooking apparatus () includes heating chamber () in which an object to be heated is rested, radiant heater unit () provided inside heating chamber () and operating in the preheating mode and cooking mode, and a control unit controlling radiant heater unit (). The control unit is configured to make radiant heater unit () operate in the standby mode, which is a mode after the preheating mode ends and until the cooking mode starts. According to this aspect, the surface temperature of radiant heater unit () is kept at a high level during the standby mode to suppress uneven browning due to variations in the surface temperature of radiant heater unit () when cooking starts.

Cooking apparatus

In a microwave heating device of the present disclosure, inverter unit drives first and second microwave generators. Cooling unit cools first and second microwave generators and inverter unit. First and second waveguides supplies, to cavity, microwaves generated by first and second microwave generators. First and second microwave generators are disposed side by side in a right-left direction below a bottom surface of cavity. Inverter unit and cooling fan are disposed from the first and second microwave generators toward a front side in order, and first and second waveguides are provided so as to extend in a front-back direction from first and second microwave generators, respectively. According to the present disclosure, the microwave heating device can be further downsized in a right-left direction.

Microwave heating device

Heating cooker () of the present disclosure includes convection device () that includes fan (), heater (), a first air guide, and second air guide, is communicated with heating chamber () through a suction port and a discharge port provided in back wall () of heating chamber (), and supplies hot air to the heating chamber (). Fan () sucks air inside heating chamber () from the suction port into convection device (), and sends out the air from the discharge port into heating chamber (). Heater () is provided in front of fan (), and heats the sucked air. The first air guide is provided so as to surround heater (), and guides the heated air to the discharge port. The second air guide is provided so as to surround fan () and the first air guide, and guides the heated air to the discharge port. A part of the second air guide is in contact with the first air guide, and another part of the second air guide is isolated from the first air guide. According to the present disclosure, it is possible to more uniformly heat the object to be heated.

Heating cooker

A cooking device includes an infrared ray sensor disposed to sense infrared radiation from food obliquely from the above. Infrared ray sensor includes a printed circuit board, a light receiving portion, a photointerrupter, and a chopper. The chopper includes a horizontal vane portion and a vertical vane portion. The chopper is disposed between the light receiving portion of infrared ray sensor and food such that the vertical vane portion passes between the light emitting device and light receiving device of photointerrupter and that horizontal vane portion passes between the light receiving portion of infrared ray sensor and food when chopper rotates. Thus, an improved microwave oven having a reduced occupied area which can be manufactured less costly can be provided.

Infrared temperature sensor for a cooking device

A heat cooker includes a generally box-like cooker body having ventholes at a bottom board thereof, a heating room disposed in the cooker body, a heat source disposed in the cooker body for heating foods in the heating room and an accessory storage section disposed under the bottom board of the cooker body, wherein the accessory storage section comprises a pair of leg bodies which support the cooker body and are attached on both sides of the bottom board and a plate-like accessory storage body which is supported by the leg bodies and inserted between the leg bodies to be capable of being pulled out forward, and wherein the leg bodies are further provided with ventilation slits that form an airway between an inside of the cooker body and an outside through the ventholes of the bottom board and an area above the plate-like accessory storage body.
