A cooking appliance includes a cooking chamber with cooking chamber wall, a microwave heat source configured to heat food, and a support device configured to hold a food-supporting member. The cooking chamber wall includes an opening and a lead-through device, and the lead-through device includes a through-hole configured to receive a fastening element of the support device. A tubular guide portion is formed at the through-hole of the lead-through device, and the tubular guide portion includes a safety portion configured to shield against microwave radiation and such that no part of the fastening element is located within the safety portion when the fastening element is in an installed condition in the lead-through device.

Heating chamber for heating food, a steam generating device for generating steam, steam chamber disposed in heating chamber, and steam introduction channel for introducing steam generated by the steam generating device to steam chamber are included. Steam chamber discharge channel for introducing water accumulated in steam chamber to outside of steam chamber is provided. Therefore, a sanitary heating cooker capable of preventing food from being immersed with condensed water, as well as preventing heating chamber from being flooded with water overflowing from steam chamber can be provided.

Provided is a cooking device capable of being provided with a radio communication device so that the radio communication device establishes a satisfactory communication, instead of (i) further providing any special configuration in which the radio communication device is provided and (ii) making any change in structure of the cooking device. According to a cooking device (1), a space for providing a radio communication adapter is secured in a frame (3b) of a door (3) or in a circuit storing section (50), made of a nonmetal, which is configured to store a driving circuit of a display operation section (5).

Cooking device includes heating chamber with door for housing object to be heated, vapor generator for supplying vapor into heating chamber, and water storage tank. Cooking device further includes cooling air passage provided between heating chamber and water storage tank and allowing cooling air to pass therethrough, and air inlet provided to the side of door and introducing cooling air into cooling air passage. This enables cooling, using a smaller and more inexpensive cooling fan. As a result, cooking device is made shorter in overall height.

A heating cooker includes heating chamber configured to house a food, through-hole formed in a wall surface of heating chamber, an imager configured to capture an image in heating chamber through through-hole, air blower configured to blow air on an outside of heating chamber, and wind guide configured to guide wind generated by air blower. Thus, wind guide is disposed so that the wind from air blower forms an air curtain passing through space between the imager and through-hole.

A heating cooker includes a housing having a heating chamber defined therein, cooking dish support sections respectively provided on mutually opposed inner wall surfaces of the heating chamber to support opposite ends of a cooking dish in one of a plurality of vertically spaced support positions, a steam generating unit, and a steam ejecting portion having a single discharge port formed in an inner wall surface of the heating chamber and a steam passageway provided to guide the steam to the discharge port. The steam ejecting portion ejects the steam into the heating chamber through the discharge port. The single discharge port is provided in the inner wall surface confronting a space between the cooking dish supported in an uppermost support position of the cooking dish support sections and a ceiling surface of the heating chamber.
