The infrared sensor 20 is set directly against the cooking appliance, that is, the infrared sensor 20 is set right above the cooking appliance to detect the temperature of the food in the cooking appliance. In practical applications, the number of infrared sensors 20 can be determined according to the number of stove eyes on the cooker. If the cooker is a single-eye cooker, only one infrared sensor 20 needs to be installed. If the cooker has N burners, then N Infrared sensor 20.

Specifically, after the range hood is powered on, the infrared sensor 20 detects the temperature of the food in the cooking utensil on the stove, generates temperature detection information, and feeds back the temperature detection information to the controller 40 . The controller 40 processes the temperature detection information and generates a temperature detection signal, and sends the temperature detection signal to the cooker through the communication module 30 in a wireless or wired manner. Judgment etc. For example, if the temperature of the food in the cooking utensils on the cooker detected by the infrared sensor 20 is greater than the preset temperature value, the cooker will reduce the current output firepower, so as to prevent fire accidents, improve the safety of the use of oil fume, and can also correct Cooking effect, prevent food from scorching and burning. At the same time, the temperature of food in the cooking utensils on the range hood detected by the infrared sensor 20 can also be used as the basis for the self-starting of the range hood's fume extraction function. For example, when the infrared sensor 20 detects that the temperature of the food in the cooking utensils on the range hood is higher than When the temperature is 60°C, it means that the cooker has started to work and the user starts cooking. If the range hood function of the range hood is not activated at this time, the controller 40 can control the range hood to activate the range hood function to prevent the user from forgetting to turn on the range hood during cooking. The fume extraction function of the hood causes too much fume in the house, thereby improving the user experience.

The alarm prompter is connected with the controller 40, wherein, when the temperature of the food detected by the infrared sensor 20 is greater than a preset temperature threshold, the controller 40 controls the alarm prompter to send out an alarm prompt message. Wherein, the preset temperature threshold may be calibrated according to actual conditions, for example, the preset temperature threshold may be 350°C.

Specifically, after the controller 40 analyzes and processes the temperature detection information, the controller 40 also compares the processed temperature data with the preset temperature threshold, for example, when the preset temperature threshold is set to 350°C, if the detected If the temperature of the food in the cooking utensil on the stove exceeds 350° C., it is considered that the cooking utensil and the food are at risk of catching fire. At this time, the controller 40 controls the alarm prompter to send an alarm prompt message. Wherein, the alarm prompt information can be completed by, but not limited to, a buzzer, a horn or a display 60. For example, the display 60 can display "the temperature of the food in the No. 1 cooking appliance has exceeded the safe temperature value, please pay attention to safety", and at the same time, The buzzer or the horn emits a prompt sound for prompting. Therefore, the range hood can effectively prevent cooking utensils and food from igniting and improve cooking safety.

To sum up, the range hood in the embodiment of the present invention detects the temperature of the food in the cooking utensil on the cooker through the infrared sensor to generate temperature detection information, communicates with the cooker through the communication module, and performs temperature detection information through the controller. Process to generate a temperature detection signal, and send the temperature detection signal to the cooker through the communication module, so that the cooker can adjust the output firepower according to the temperature detection signal, so that the cooking effect can be corrected and fire accidents can be prevented. At the same time, the temperature detection signal can also be used as a cooking fume It is based on the self-starting of the range hood to prevent too much oil fume in the house due to the user forgetting to turn on the range hood function when cooking. Moreover, the user can view the real-time temperature of the cooking food in real time through the display, so that the user has an accurate understanding of the temperature of the cooking food during the cooking process, which solves the problem that the user cannot clearly know the food temperature during the cooking process and can only judge through experience It provides a technical guarantee for significantly improving the cooking effect. Moreover, when the temperature of the food in the cooking appliance is too high, an alarm message is sent to remind the user to take corresponding measures, making the hood smarter, safer and easier to use, improving product power and user inspection.

Fig. 3 is a flowchart of a method for controlling a range hood according to an embodiment of the present invention. As shown in Figure 3, the control method of the range hood includes the following steps:
