Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker for heating and cooking an object to be heated, and more particularly to an improvement of a temperature measuring mechanism for measuring the temperature of the object to be heated.

[0002]

2. Description of the Related Art An electric heating cooker capable of electrically cooking with a heating coil has been in high demand due to its safety without using fire and energy efficiency for heating an object to be heated. In such an electric cooker,
Detecting the temperature of the object to be heated during cooking is necessary for controlling the output of the heating coil and for accurately performing the cooking, and various methods have been conventionally used.

FIG. 11 shows a schematic view of a conventional heating cooker described in Japanese Patent Laid-Open No. 2000-268951.
The heating cooker 100 shown in the figure is a built-in type that is built in the kitchen 101, and a top plate 103 is provided on the top surface 102 of the main body. Then, the top plate 103 has a left heating portion 104, a right heating portion 105, and a central heating portion 106.
It has three heating parts. Also, the front side 10 of the main body
7, the roaster 108 is on the left and each heating part 1 is on the right.
Operation unit 1 for performing various operations such as heating output of 04, 105, 106 and roaster 108 and power management of the apparatus.
09 are provided.

FIG. 12 shows a temperature detecting mechanism of an electric heating cooker having such a structure. FIG. 12 is an explanatory diagram for explaining a mechanism for placing an object to be heated on the heating portion shown in FIG. 11 and detecting the temperature of the object to be heated. As shown in the figure, the left, right, and center heating portions 104, 10 are respectively provided.
A heating coil 110 is provided below the reference numerals 5 and 106 with the top plate 103 interposed therebetween. A temperature detecting element 112 is provided below the heating portion with the top plate 103 interposed therebetween in order to detect the temperature of the object to be heated 111 placed on the heating portion. Thereby, the temperature of the object to be heated 111 heated by the heating coil 110 is transmitted to the top plate 103,
The temperature can be detected by the temperature detecting element 112 from the top plate 103.

[0005]

However, in the structure in which the temperature of the object to be heated 111 is detected by sandwiching the top plate 103 as described above, the temperature of the object to be heated 111 is transmitted to the top plate 103, and the top plate 103. Since the temperature is detected as the temperature of the object to be heated 111, the temperature response is inevitably poor, and the actual temperature itself of the object to be heated 111 cannot be detected. In particular, if the rate of temperature increase due to heating is large, there is a problem in that a temperature greatly different from the actual temperature of the object to be heated 111 is detected.

On the other hand, in a gas stove or the like, the temperature detecting element is made to project from the heating portion of the top plate and is brought into direct contact with the object to be heated placed on the heating portion to detect the temperature of the object to be heated. There was also a cooker. However, when the structure in which the temperature detecting element is brought into direct contact with the lower part of the object to be heated is applied to the electric heating cooker, the temperature detecting element has to protrude from the heating portion, which is a characteristic feature of the electric heating cooker. There is a problem that the flat top plate hinders the ease of cleaning and the good appearance.

The present invention has been made in view of the above problems, and an object thereof is to provide an electric heating cooker capable of accurately measuring the temperature of an object to be heated without impairing the smoothness of the top plate. It is a thing.
