The working principle and the control method of the range hood of the present invention are briefly described below with reference to fig. 5: the utility model discloses a range hood switch on, range hood are cooking through 2 monitoring users of action inductor, and range hood passes through the temperature that 3 monitoring cooking utensils are regional through the temperature-sensing ware whether rise to the temperature of procedure setting, and range hood passes through the luminance of photosensitive sensor 4 monitoring kitchen environment.
When it is monitored that the user is cooking and the temperature of the cooking area rises to the programmed temperature, the control circuit board automatically starts the fan to suck away the oil smoke, specifically, when the temperature of any object in the cooking area first reaches the programmed temperature, the control circuit board judges that the temperature of the cooking area rises to the programmed temperature, for example, a round bottom iron pan and a flat bottom frying pan are respectively placed on two burners of the cooking range 99, the temperature of one of the round bottom iron pan and the flat bottom frying pan rises to the programmed temperature, and the fan is automatically started when it is monitored that the user is cooking.
When the cooking operation is monitored to stop (namely, a user does not cook) and the range area is in a high-temperature state range set by a program, the control circuit board controls the alarm device to give an alarm, and then when the user needs to recover the cooking, the user can turn off the alarm device in a manual mode, but if the cooking operation is monitored to stop again, the control circuit board controls the alarm device to give an alarm.
When the temperature of the range area is monitored to be lower than the high-temperature state range set by the program, the control circuit board automatically closes the alarm device.
When the situation that the user is cooking is monitored, the control circuit board controls the lighting source 6 to be turned on; when the user is monitored to be cooking and the brightness of the kitchen environment is monitored to be bright, the control circuit board controls the lighting source 6 to be switched into a low-brightness mode; when the user is detected to be cooking and the brightness of the kitchen environment is detected to be dim, the control circuit board controls the illumination light source 6 to switch to the high brightness mode.
When the user is cooking and the temperature of the cooker area is increased to the temperature set by the program, the control circuit board controls the illumination light source 6 to be switched to the high-brightness mode, that is, when two conditions that the user is cooking and the temperature of the cooker area is increased to the temperature set by the program are met, the control circuit board locks the illumination light source 6 to be the high-brightness mode and ignores the light brightness factor of the kitchen environment.
