Problems solved by technology

[0004] As mentioned above, in the prior art, only a single infrared sensor is used to determine the temperature inside the cooking chamber. Since the sensing area of ​​a single infrared sensor is small, it is impossible to accurately determine the state of the food with the measured temperature. Food is burnt or undercooked

Embodiment Construction

[0017] Hereinafter, the microwave oven of the present invention will be described in detail with reference to the accompanying drawings and embodiments.

[0018] Such as figure 2 , 3 As shown, the main body of the microwave oven of the present invention is composed of a cooking chamber in which food is put in and heated, and a control chamber in which electrical devices such as magnetrons are installed, and an operating panel capable of controlling the operation of the microwave oven is also provided. A plurality of buttons for inputting an operation signal of the microwave oven and a display unit for displaying the operation signal of the microwave oven are provided on the operation panel.

[0019] Such as figure 2 As shown, an array type infrared sensor (hereinafter referred to as an infrared sensor) composed of a plurality of infrared sensors is installed on one side of the cooking chamber of the microwave oven. That is, it consists of an upper sensor frame A1, an uppe...

Abstract

The invention provides a microwave oven. It includes cooking chamber, tray, control chamber and driving device. It is characterized by that in the described control chamber a temperature sensing component formed from several infrared sensors in the array mode and a microcontroller connected with signal input component and infrared sensor component are set, and said microcontroller is connected with driving device containing heater driving portion and magnetron driving portion, and said driving device can be used for receiving the heating energy output control signal of said microcontroller, and can deliver the heat quantity of microwave produced by heater into the inside of cooking chamber.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a microwave oven which measures the temperature of the upper part of the chassis inside the microwave oven into multiple areas at the same time. Background technique [0002] Such as figure 1 As shown, in the prior art, in order to detect the temperature of the food inside the cooking chamber, an infrared sensor 3 as a temperature detection device is used, and the heating temperature is controlled by the temperature detection result of the infrared sensor 3 . As described above, when the temperature inside the microwave oven is measured by a single infrared sensor, only a part of the upper part of the chassis T inside the cooking chamber can be detected. Therefore, when the food is located outside the detectable range, the temperature of the food cannot be accurately measured, and thus, it is impossible to accurately control the heating of the food. [0003] As shown in the figure, the infra...
