摘要： A microwave oven providing the combination of dielectric heating by the use of microwaves and resistive heating for scorching the surface of a food. An isolation chamber for accommodating an article to be heated by a resistive heater is formed adjacent to the resistive heater provided in a heating cavity. When heating by the resistive heater is desired, the article to be heated is accommodated in the isolation chamber so that it is heated either both by dielectric heating and resistive heating or solely by resistive heating for scorching in an effective manner and at the same time minimizing the contamination of the heating cavity. In this manner, the application of the microwave oven may be widened and the usefulness of the microwave is enhanced.

摘要： A microwave oven is equipped with a rotary table driven by magnetic coupling. The microwave oven has a heating chamber in which at least its bottom wall or base plate is made of a non-magnetic metallic material, while its other walls are formed of metallic material other than non-magnetic metallic material, for reduction of the cost of the microwave oven. The junctions between the wall of non-magnetic metallic material and the walls of metallic material other than non-magnetic metallic material are coated with coating film to improve corrosion resistance. Furthermore, the heating chamber together with the rotary table is so arranged as to facilitate insertion and withdrawal of a container of food material into and from the heating chamber to provide a microwave oven which is clean and convenient to use.

摘要： The invention is related to improvements in a cooking appliance equipped with both a microwave heating means and a hot air circulation heating means. By controlling the rotational speed of an air circulating fan or the power of heater means according to the kind of food to be cooked, the cooking time is shortened and the quality of cooked food is improved. The hot air discharging section of such an oven includes a perforated plate so as to prevent leakage of microwaves from the heating chamber, and an air baffle means is provided strategically in the hot air discharging section to ensure a uniform distribution of temperature within the heating chamber. The invention also includes an improved relative position of the air inlets, a double-deck tray and the air baffle means which functions to prevent a substantive dehydration of food which is a drawback of a conventional hot air circulation heating system.

摘要： A structure of a microwave oven door screen which facilitates the observation of the inside of a heating cavity and enhances the safety against the electromagnetic wave leakage and durability. A door screen of this type generally comprises a pair of transparent plates and an electromagnetic wave shielding material interposed therebetween. The present door screen uses a punched metal plate as the electromagnetic shielding material made of aluminum having a thickness of 0.1 to 0.35 mm, an aperture diameter of 1.2 mm or less and a ratio of the aperture diameter to a center-to-center distance of an aperture of 0.67 to 0.85, these parameters being chosen such that an aperture rate of more than 40% is assured and the electromagnetic wave leakage through the door screen is effectively prevented (to meet the Regulations of U.S. Department of Health, Education, and Welfare) and a strain due to continuous mechanical treatment of the punched metal plate is minimized.

摘要： A cooking device with one cooking or heating chamber in which food may be heated by either one or both of high-frequency heating means and the resistance heating means. The high-frequency or microwave energy is radiated into the heating chamber from the top while the air heated to high temperatures by the resistance heating means disposed within a rear chamber defined back of the rear wall of the heating chamber is circulated therethrough by a circulation fan. Food charges are placed on a receptacle which in turn is placed on a turntable, whereby the food charges may be uniformly heated. The simultaneous use of both the high frequency heating means and the resistance heating means may enable a more wide variety of food to be cooked by a more wide variety of methods.
