Problems solved by technology

[0004] However, according to the existing heating control technology, there is a problem that it is difficult to control boiling water, that is, to use an infrared sensor to monitor the temperature of the bottom surface of the container while boiling water at a low temperature of 100°C, which is the cooking temperature, and to remove Such as chlorine, etc., and continue to heat for a period of time

no. 1 approach

[0045] Below, refer to Figure 1 to Figure 7 , the first embodiment applied to the induction heating cooker incorporated in the kitchen will be described.

[0046] like image 3 , 4 As shown, the cooker main body 3 of the heating cooker 2 is assembled in a state of being inserted into the opening 4 provided in the cabinet 1 . In the lower part of the cooker main body 3, a grill part 5 is provided.

[0047] like Figure 4 As shown, the upper surface of the cooker main body 3 is open, and two induction heating coils 8, 9 are provided as heaters on the front side of the interior, and a heater 10 composed of a radiation heater, for example, is provided as another heater in the central interior. heater. A display circuit board 11 is arranged in the cooking device main body 3 . On the display circuit board 11 are mounted display groups 12A, 12B composed of a plurality of light-emitting diodes for displaying heating intensity, and displays 15A, 15B composed of fluorescent displ...

no. 2 approach

[0204] Figure 8 ~ Figure 11 The second embodiment is shown, and the same reference signs are attached to the same parts as those in the first embodiment to omit description, and the different parts will be described below.

[0205] Figure 9 An example of the warm-up control data series (except for the data series (10)) stored and held in the internal memory of the thermal power control device 41 as a data table is shown. Figure 9 The axis of abscissas represents the scale of the lower surface temperature Tpu of the top plate 16 and the output voltage Vto of the infrared sensor 32, and the axis of ordinates represents the thermal power output P of the induction heating. In addition, data series (1) to (9) show a series of warm-up control data (temperature rise control data) using as a parameter the lower surface temperature Tpu which rises in units of 25°C from 25°C.

[0206] At this time, according to the infrared energy radiated when the bottom temperature of the shiny s...

Abstract

An induction heating cooker for detecting water boiling precisely and realizing water-boiling control is provided. An induction heating cooker of an embodiment is provided with a glass top plate (16)for placing heated objects (35); a heater(48) arranged below the top plate and used for releasing induction heating of the heated objects (35) through a heating coil; an infrared sensor (32)for detecting infrared radiating from the top plate (16) and the heated objects(35); a control part (41) for monitoring the infrared detection value and change rate of the infrared sensor (32), and controlling firepower of the heater according to the infrared detection value and the change rate. The control part (41) is used for realizing boiling detection according to the detection value of the infrared sensor (32), calculating the load capacity of the heated objects (35) of the top plate according to the infrared detection value of the boiling detection and the changing rate of the infrared detection value before the boiling rate, and controlling firepower of the heater after the boiling detection according to the load capacity.

Description

[0001] This application is based on Japanese Invention Patent Applications 2011-070853 and 2011-070854 (filing date: March 28, 2010), and enjoys the priority of said earlier applications. This application incorporates said earlier application by reference in its entirety. technical field [0002] Embodiment of this invention relates to an induction heating cooker. Background technique [0003] In a conventional induction heating cooker, an infrared sensor for detecting infrared rays radiated from an object to be heated and a temperature sensor for detecting the temperature of the top plate are provided below the top plate. In addition, there is a technique of calculating the temperature of the heating container from the signal of the infrared sensor and the temperature sensor when the temperature of the top plate is low. [0004] However, according to the existing heating control technology, there is a problem that it is difficult to control boiling water, that is, to use a...
