  However, the conventional drawer-type heating cooker has a problem that the switch operating lever for operating the microwave transmission switch protrudes from the open / close door, which interferes with taking in and out the object to be heated and has poor cleaning properties. . In addition, it is necessary to provide a hole facing the operating lever at the periphery of the opening of the heating chamber, and it is necessary to devise structural measures in terms of safety so that the oscillation switch cannot be operated from this hole when the door is opened. It was.

  The present applicant has proposed a cooking device in which a drawer body in which an object to be heated is accommodated can be pulled out from the cooking device body (Japanese Patent Application No. 2004-7385). According to this heating cooker, it is not necessary to use an effective part or material having high heat resistance and flame retardancy to constitute the moving mechanism, so that the manufacturing cost can be reduced and the moving mechanism is heated. By adopting a structure that is not affected by the microwave applied to the room, the possibility of discharge due to the microwave can be eliminated.

  In an electromagnetic cooker using microwaves, if the main switch for generating microwaves is activated when the door is open, the microwave will leak out of the cooker, making it dangerous. Designed to turn on the main switch. However, in the drawer-type heating cooker in which the drawer body can be pulled out from the cooker main body by the slide rail, if the operation mechanism of the microwave oscillation stop switch is arranged on the front surface of the cooker main body, the opening / closing door is not provided. There is a possibility that the operating mechanism is operated by misoperation or mischief in the opened state, and the switch is turned on. In addition, when the operation mechanism of the microwave oscillation stop switch is arranged on the back surface of the cooker body, the slide rail can pass through the passage hole formed on the front surface of the cooker body. It can be said that there is no possibility of operating the switch through mischief or accidentally passing through the metal fitting between the rail and the movable rail.

  Therefore, in the drawer-type heating cooker in which the drawer body including the heating container can be pulled out through the slide mechanism with respect to the cooker main body, paying attention to the fact that the slide mechanism extends inside the cooker main body, There is a problem to be solved in that a movement capable of causing the operation of the microwave oscillation stop switch to be generated based on the opening / closing operation of the inside of the cooker body is obtained.

  An object of the present invention is to enable the drawer body to be pulled out from the cooker body via the slide mechanism, and to prevent the microwave oscillation stop switch from operating unintentionally due to erroneous operation or mischief. Is to provide a cooker.
