Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.

Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.

Described a kind of smoke exhaust ventilator automaton, including smoke exhaust ventilator body 1, described smoke exhaust ventilator body 1 includes coaming plate 11, the casing 12 being located in coaming plate 11, the wind cabinet assembly 13 being located in casing 12, the upper glass plates 14 being located at casing 12 upper front end, the lower panel 15 being located at casing front lower portion, the main switch 16 that is located in upper glass plates 14, form air inlet between described upper glass plates 14, lower panel 15；The air inlet side of described lower panel 15 is provided with switch detector 2, and this switch detector 2 includes flame-detecting probe 21 and infrared temperature detection probe 22；The air inlet side of described upper glass plates 14 is provided with photoelectric smoke sensor 3, and this photoelectric smoke sensor 3 is made up of optical transmitting set 31 and optical receiver 32, and is provided with optical filter on described optical receiver 32；Being provided with control assembly 4 on described casing 12, described control assembly 4 is electrically connected with switch detector 2, photoelectric smoke sensor 3 respectively.

Being provided with LED 151 on described lower panel 15, and be provided with lamp box 17 at the side of wind cabinet assembly 13, the lower section of described casing 12 goes out to be provided with lubricating cup 5 near kitchen range.

Described wind cabinet assembly 13 includes cabinet 13a, the motor 13b being located in cabinet 13a, the wind wheel 13c being located on motor 13b, the Inlet Network 13d that is located on cabinet 13a.

Its operation principle is:

In smoke exhaust ventilator automatic switching: the air inlet side of plate 15 is provided with switch detector 2 below, this switch detector 2 includes flame-detecting probe 21 and infrared temperature detection probe 22.For using the kitchen range of gas combustion heating, after kitchen range are opened, flame-detecting probe 21 can detect the infrared ray that the flame of kitchen range sends in time, now, flame-detecting probe 21 sends data to the single-chip microcomputer controlled in assembly 4, and single-chip microcomputer sends instruction to smoke exhaust ventilator and opens cigarette machine simultaneously；After kitchen range cut out, flame-detecting probe 21 detects the infrared ray sent less than kitchen range flame, and single-chip microcomputer does not receive signal, then send out code to smoke exhaust ventilator.Kitchen range for non-pneumatic combustion heating, such as electromagnetic oven class, then detected by infrared temperature detection probe 22, after the kitchen range of non-pneumatic combustion heating are opened, cooking apparatus is persistently overheating, simultaneously single-chip microcomputer receives the data sent by infrared temperature detection probe 22 continuing, received data is analyzed judging by single-chip microcomputer, within the specific time period, the constant temperature of cooking apparatus rises, single-chip microcomputer is to being judged as that smoke exhaust ventilator entry condition meets, and sends open command to smoke exhaust ventilator；After the kitchen range of non-pneumatic combustion heating cut out, cooking apparatus is owing to without heating source, then temperature is on a declining curve, when the temperature data that single-chip microcomputer receives reaches the numerical value the continuous decrease that set, single-chip microcomputer is judged to that smoke exhaust ventilator cut-off condition meets, and sends shutdown command to smoke exhaust ventilator.In two kinds of above detection patterns, by single-chip microcomputer to any preferentially meet compressor start up condition start-up mode be analyzed, it is judged that the mode of heating of user is also suitable for different shutdown modes.

The air inlet side of upper glass plates 14 is provided with photoelectric smoke sensor 3, and this photoelectric smoke sensor 3 is made up of optical transmitting set 31 and optical receiver 32.After smoke exhaust ventilator is opened, photoelectric smoke sensor 3 opens work, different from the detection mode that the patent No. is 201520177577.X device, the patent No. is the mode that the device of 201520177577.X uses is after light is blocked by smog, the optical signal that optical receiver 32 receives weakens to judge the size of smog, smokescope is more high, and receiving end signal is more weak, then motor speed is more high；Smokescope is more few, and receiving end signal is more strong, then motor speed is more low, and its structural design is the air inlet two ends that optical transmitting set 31 and optical receiver 32 lay respectively at smoke exhaust ventilator.The reflection of what this patent used is light is to judge the size of smog, and optical transmitting set 31 and optical receiver 32 are at same place, the specific light source (selecting visible ray or black light light source according to different installation sites) that this photoelectric smoke sensor 3 sends.When not having smog to pass through photoelectric smoke sensor 3 detection zone, optical receiver 32 cannot receive optical signal；Have smog pass through photoelectric smoke sensor 3 detect interval time, the specific light source that photoelectric smoke sensor 3 sends can be reflected by smog, and now the optical receiver 32 of photoelectric smoke sensor 3 then can receive the flashlight reflected by smog.The flashlight of the more big reflection of amount of smoke is more strong, the more little reflected signal light of amount of smoke is more weak, according to this principle, the concentration of cigarette machine is judged, and sent different rotary speed instructions by the single-chip microcomputer controlling part to motor, it is achieved according to the big small machine self-shifting function of oil smoke concentration.

The electronic devices and components used in optical receiver 32 in this photoelectric smoke sensor 3 are extremely sensitive to infrared ray produced by flame, simultaneously in order to prevent external light source from affecting, optical receiver 32 adds optical filter, it is after receiving infrared ray produced by flame, produce higher voltage signal, this signal intensity be smog reflection flashlight produced by tens times of voltage, now single-chip microcomputer is judged to the accident that user occurs cooking apparatus on fire in cooking process, out-of-work instruction is sent immediately to motor, prevent flare owing to negative pressure produced when fume exhauster motor operates is by flare inspiration smoke exhaust ventilator breaking out of fire accident.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
