Problems solved by technology

However, because the heating control amount and the heating time are controlled according to the surface temperature of the food measured based on the output of the infrared solid-state imaging element before heating, instead of detecting the temperature of the food in the heating cooking after the heating is started with infrared rays and The heating control amount is controlled based on the detection, so the finished state of different foods will deviate

Embodiment approach 1

[0032] (Structure of heating cooker)

[0033] figure 1 It is a front view of the heating cooker which concerns on embodiment of this invention. figure 2 The internal structure of the heating cooker 1 is schematically shown, image 3 A block diagram configuration of the heating cooker 1 is shown.

[0034] refer to figure 1 and figure 2 , in the inside of the box of the heating cooker 1, a heating chamber 3 is provided as a box with an open front surface. The door 2 is rotatably attached to the front opening of the heating chamber 3 . Window glass is attached to the door 2 so that the inside of the heating chamber 3 can be seen visually. The window glass is implemented with measures to prevent the leakage of high-frequency waves.

[0035] On the front surface of the box and on the upper part of the door 2, a touch panel 22 is provided. The touch panel 22 includes: a key input unit, which is touched and operated as an input unit when selecting a menu and a heating mode;...

Embodiment approach 2

[0106] Cooker 1 further includes an irradiation position changing unit for changing the irradiation position of high-frequency waves from magnetron 31 . The CPU 6 controls the irradiation position changing unit to change the irradiation position of the high-frequency wave according to the temperatures detected by the infrared array sensor 21 at a plurality of locations.

[0107] Specifically, when the heating cooker 1 detects a part with a high temperature and a part with a low temperature of the object to be heated 11 from the temperature group of the temperature sequence obtained from the output of the infrared array sensor 21 during the heating according to the heating sequence, the CPU 6 Based on the output of the rotation angle detector 24, each antenna motor 32 corresponding to the irradiation position changing unit is controlled to rotate the corresponding rotating antenna 4, thereby moving the microwave-irradiated part of the object 11 to be heated. Thereby, the positi...

Abstract

This thermal cooker (1) is provided with: a thermal chamber (3) for accomodating a material being heated (11); an infrared sensor for detecting the temperature at multiple locations within a viewing angle that includes the material being heated; a high-frequency wave generating device for generating high-frequency waves for heating the material being heated; and a control unit for controlling heating of the material being heated, through control of the high-frequency wave generating device in accordance with a heating sequence. The control unit includes a type detector that, on the basis of the temperature detected at multiple locations by the infrared sensor, detects the type of material being heated, and the control unit controls heating of the material being heated, on the basis of the detected type.

Description

technical field [0001] The present invention relates to a heating cooker, and more particularly to a heating cooker for cooking while detecting the temperature in a heating chamber using an infrared sensor. Background technique [0002] Among commercially available heating cookers, there is a heating cooker having a function of detecting the food temperature in the heating chamber with an infrared sensor. Specifically, there are known cooking devices that detect the temperature at a fixed position of food with a single-eye sensor, and cooking devices that measure the temperature distribution of food by swinging a plurality of linear infrared sensors. [0003] According to Japanese Patent Laid-Open Publication No. 2002-317937 (Patent Document 1), in a microwave heating cooking device, a two-dimensional infrared solid-state imaging device is fixed on the ceiling surface of the cooking chamber. Before starting heating, measure the surface temperature of the food from the tempe...
