Abstract: A microwave oven includes a waveguide having an E-bend structure with multiple openings disposed on a lateral face of a heating chamber that allow the waveguide to communicate with the heating chamber. The waveguide has a first section for propagating a microwave from a magnetron toward the heating chamber, and a second section having a wide plane that abuts an outer wall of the heating chamber. The openings include at least one circularly-polarized-wave opening for generating a circularly polarized wave. A cross section of the first section orthogonally intersects a tube axis of the first section projects virtually along the tube axis of first section and onto a lateral face of the heating chamber, and the circularly-polarized-wave opening is configured such that its center is located outside the resultant projected region.

Abstract: Provided is an induction heating cooker which can be carried to a desired position on a cooking table to conduct grill cooking using induction heating and radiation heating and includes a grill tray (8) that is placed inside a heating chamber (7) and includes an engaging section that is used for removing the grill tray (8) from the heating chamber (7) and inserting the grill tray (8) into the heating chamber (7). The grill tray (8) is configured as being placeable on a cooking table. Grill cooking is conducted using an upper heating unit which is provided above the heating chamber (7) and heats a food item inside the heating chamber (7) by radiation and a lower heating unit which is provided below the heating chamber and heats the grill tray by induction.

Abstract: Provided is an induction heating cooker which can be carried to a desired position on a cooking table to conduct grill cooking using induction heating and radiation heating and is configured such that a cooling fan forms an airflow in a plurality of vent channels inside a main body. The plurality of vent channels include a first vent channel. The first vent channel is configured such that an airflow from the cooling fan is directly guided from the cooling fan to an air outlet. The first vent channel is configured such that the airflow from the cooling fan and an airflow from a heating chamber are mixed.

Abstract: Microwave oven (20) includes waveguide (3) having an E-bend structure, and multiple openings (4a, 4b). Waveguide (3) has first section (3a) for propagating a microwave from magnetron (2) toward heating chamber (1), and second section (3b) of which wide plane abuts on the outer wall of heating chamber (1). Multiple openings (4a, 4b) are disposed on a lateral face of heating chamber (1). Openings (4a, 4b) allow waveguide (3) to communicate with heating chamber (1), and include at least one circularly-polarized-wave opening (4a) for generating a circularly polarized wave. A cross section of first section (3a) orthogonally intersecting tube axis (7a) of first section (3a) is projected virtually along tube axis (7a) of first section (3a) onto a lateral face of heating chamber (1), and circularly-polarized-wave opening (4a) is formed such that its center is located outside the resultant projected region defined by this projection.

Abstract: To prevent parts within a heating chamber from melting to thereby secure the safety of a goods even when a user sets an arbitrary time and operates. There are provided with a temperature detector 5 for detecting the temperature of a food within the heating chamber 1 in a non-contact manner, a high-frequency generator 14 for generating a microwave to heat the food within the heating chamber, and a controller 7 for controlling the high-frequency generator based on an output from the temperature detector. The controller is configured in a manner that when a user sets an arbitrary time and inputs a cooking start operation, in a menu for executing the high-frequency heating during the set time, the output level of the high-frequency generator is controlled so as to be reduced when the temperature obtained from the temperature detector increases a predetermined value or more.

Abstract: An object of the present invention is to provide a high frequency heating apparatus having a steam generating function in which a time required for evaporation of dropped water can be remarkably increased when water is dropped onto an evaporation tray and the heating efficiency is high. The high frequency heating apparatus has a steam generating function that includes a high frequency generator and a steam generator that includes an evaporation tray provided on the bottom surface of a heating chamber in which a heating target is mounted and a heater device for heating the evaporation tray to generate steam in the heating chamber, wherein the heater device is constructed as a heater device (11) having a sheathed heater (113) embedded in an aluminum die cast (111), and the heater device is directly attached to the back side of the evaporation tray (22).
