Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric cooker equipped with a plurality of heat sources and a rack for supporting food to be cooked.

Conventional technology Conventional electric cookers of this type include, for example, the
As shown in Publication No. 3395, it had a configuration as shown in FIG.

That is, a lower heater 2 is embedded and attached to the lower part of a frying pan-shaped container 1, an upper heater 4 is provided in a lid 3 covering the container 1, and a temperature sensing probe 5 and a pair of power terminals 6 are provided. By attaching the constant temperature control device 7 to the recess 8 of the container 1, cooking in a frying pan is performed, and by attaching the constant temperature control device 7 to the upper heater 4 of the lid 3, cooking in an oven is performed. . And when making this oven dish, put 9 racks in 1 container.
Place the food on the rack 9 and cook.

Problems to be Solved by the Invention However, with such a structure, when cooking in an oven in an atmosphere, heating is not performed from below, resulting in significant uneven cooking, making it impossible to obtain delicious food. Also, the position of the food relative to the heater has a great effect on uneven cooking and the degree of heat, but since the rack 9 is placed on the bottom of the container 1, there is a large deviation in the radial direction of the container 9. Positioning was difficult, and the rack 9 could damage the inner surface (especially the cooking surface) of the container 1. Further, in this configuration, the flatness of the bottom surface of the container 1 is important, so that it cannot be used with a non-flat pot bottom shape such as a wok. Furthermore, when changing the cooking performance by changing the height of the rack 9, it is possible to provide two different lengths of the support part 10 of the rack 9, upper and lower, but since the rack 9 is supported on the bottom of the container 1, In order to make a large change, a very long support part 10 is required, resulting in problems such as poor operability.

In view of the current situation, it is an object of the present invention to provide an electric cooker that allows cooking under optimal heating conditions, allows for easy positioning of a rack on which food is placed, and is also capable of steam cooking. It is.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a pot-shaped container with a step formed at the upper part of the opening, a food receiving part, and a height direction with respect to the food receiving part. a rack having a supporting part that is placed and supported on the stepped part of the container in a removable manner; a lid that covers the upper opening of the container; and an upper heater provided above the inside of the lid. , and a lower heater provided below the container, and depending on the type of cooking, the rack can be set upside down so that the food receiving portion is positioned close to the lower heater or closer to the upper heater. It was designed to be switched.

Effects According to the above configuration, accurate heating by the upper and lower heaters enables cooking with less uneven cooking, and since the support part of the rack is supported at the periphery of the upper opening of the container, it may damage the cooking surface of the container. In addition, since the food receiving part faces near the bottom of the container, the food is heated indirectly, and by placing the food close to the lower heater, which has a weaker heating, it is easier to finish the oven food. In addition, the effective usable volume is increased, and in the case of high-heat heating, grilling can be easily done by setting the rack in the opposite direction and bringing the food closer to the upper heater. Furthermore, if the rack is set in the opposite direction so that the food receiving portion faces upward, a sufficient amount of water necessary for steaming can be poured into the container, and steam cooking can be performed satisfactorily.
