The detection port of the oil fume and water vapor laser detector is facing the ventilation mesh 20. The surface is provided with a hood air inlet 24, and the left and right sides of the hood body 5 are fixedly installed with Mounting seats 26 on both sides, the bottom of the hood body 5 are fixedly installed with the bottom mounting seat 27, and the hood body 5 is threadedly installed on the inner wall of the hood box 1 through the mounting seats 26 on both sides and the bottom mounting seat 27. The front surface is fixedly installed with a front mounting seat 25, which is fixedly connected to the first mounting seat 35 of the smoke pipe. hole 22 and display installation slot 23, the base plate body 21 is fixedly installed on the inner wall of the oil fume inlet box 14, the base plate body 21 is penetrated with a ventilation mesh 20, and the left side of the base plate body 21 is reserved with a display installation groove, for display installation A display 13 is fixedly installed in the groove, and a first mounting hole 19 and a second mounting hole 22 are opened through the bottom plate body 21. The internal thread of the first mounting hole 19 is installed with a baffle plate 12, and the baffle plate 11 is fixedly installed on the baffle plate 12. , the second mounting hole 22 is internally threaded with a connecting plate 10, the connecting plate 10 is hinged to be equipped with a baffle 11, the air outlet end of the auxiliary air outlet 4 is provided with a protective net, and the thermocouple temperature detector 34 passes through The Bluetooth module and the hood body 5 realize data interaction, and the oil fume and water vapor laser detector 9 realizes data interaction with the hood body 5 through the Bluetooth module. When the thermocouple temperature detector 34 in the oil fume inlet box 14 detects that the temperature rises above 150 degrees, the thermocouple temperature detector 34 transmits the detected temperature information to the thermal energy detection control module through the Bluetooth module, and the thermal energy detection control module detects After receiving the incoming temperature information, give the hood control unit a control command, the hood control unit controls the hood body 5 to open the baffle 11, and at the same time the frequency conversion motor starts to work at the intermediate frequency speed. During cooking, oily smoke and water vapor are generated under the baffle 11 , when the oil fume water vapor rises into the oil fume inlet box 14, the oil fume water vapor laser emitting module in the oil fume water vapor laser detector 9 transmits a signal to the oil fume water vapor in the oil fume inlet box 14, and the oil fume water vapor laser receiving module receives the signal reflected by the oil fume water vapor, And the signal is transmitted to the hood controller unit through the bluetooth module. When the concentration of oil fume and water vapor is high, the signal reflected by the oil fume and water vapor laser receiving module is weak. When the concentration of oil fume and water vapor is small, the oil fume and water vapor laser receiving module receives the reflection The returned signal is strong, when the signal sent by the oil fume and water vapor laser detector 9 is weak, the hood controller unit controls the wind wheel to increase the speed greatly, and when the signal sent by the oil fume and water vapor laser detector 9 is strong, the hood controller unit controls the wind wheel to increase slightly Rotational speed, when cooking is stopped and the fire is turned off, the hood body 5 continues to work. When the oil fume and water vapor laser detector 9 cannot detect the oil fume and water vapor, the hood controller unit controls the speed of the fan wheel of the hood from high to low, and works for a period of time After the hood is turned off, when the hood is working and the internal channel of the hood is blocked, the output current of the frequency conversion motor in the hood body becomes larger, and when the hood controller unit detects that the current becomes larger, the hood controller unit controls the wind wheel Increase the rotating speed, and the display 13 is used to display the hood When the working condition of the hood is blocked, and part of the fume and water vapor has not been completely removed, the residual or undischarged oil fume and water vapor will be discharged through the auxiliary smoke exhaust pipe 6.
[0023] The working principle of the present invention is: when using the hood, turn on the switch at the bottom of the hood, and the temperature will rise. The dual temperature detector 34 transmits the detected temperature information to the thermal energy detection control module through the bluetooth module. After the thermal energy detection control module detects the incoming temperature information, it gives control instructions to the hood control unit, and the hood control unit controls the hood body. 5. Open the baffle plate 11, and at the same time, the variable frequency motor starts to work at the intermediate frequency speed. During cooking, soot and water vapor are generated under the baffle plate 11. The module transmits signals to the oil fume and water vapor in the oil fume inlet box 14, and the oil fume and water vapor laser receiving module receives the signal reflected by the oil fume and water vapor, and transmits the signal to the hood controller unit through the Bluetooth module. When the concentration of oil fume and water vapor is high, the oil fume and water vapor laser The receiving module accepts the signal reflected by the oil fume and water vapor to be weak. When the concentration of oil fume and water vapor is small, the signal reflected by the oil fume and water vapor laser receiving module is strong. When the signal sent by the oil fume and water vapor laser detector 9 is weak, the hood controller unit controls the wind The rotation speed of the wheel is greatly increased. When the oil fume and water vapor laser detector 9 sends a strong signal, the hood controller unit controls the wind wheel to increase the speed slightly. When cooking is stopped and the fire is turned off, the hood body 5 continues to work. When the oil fume and water vapor laser detector 9 cannot When oil fume and water vapor are detected, the controller unit of the hood will control the speed of the wind wheel of the hood from high to low, and after working for a period of time, the hood will shut down. The output current of the hood becomes larger, and when the hood controller unit detects that the current becomes larger, the hood controller unit controls the wind wheel to increase the rotating speed, and the display 13 is used to display the working condition of the hood, the internal blockage of the hood body, and some oil fumes. When the water vapor is not completely removed, the residual or unable to discharge oily smoke and water vapor will be discharged through the auxiliary smoke exhaust pipe 6 .
