Detailed description of the invention
Refer to Fig. 1, the cooking apparatus 10 shown in figure includes gas oven 11 and a range hood 13.Gas oven 11 has a burner 12, and range hood 13 has a casing 14 and and is located at air exhauster 15 in casing 14, and casing 14 has a monitoring mouth 16, and monitoring mouth 16 corresponds to the burner 12 of gas oven 11.Referring again to Fig. 2 and Fig. 3, flame sensing apparatus 18 of the present invention includes flame sensor 20 and a baffle 50.
Flame sensor 20 to be located in casing 14 and to be had control box 40, short wave ultraviolet sensing component 30, and a circuit board 32.Control box 40 is fixed on casing 14 and has an installing port 44, and installing port 44 corresponds to the monitoring mouth 16 of casing 14; Short wave ultraviolet sensing component 30 to be located in control box 40 and in the present embodiment via the monitoring mouth 16 of the corresponding casing 14 of installing port 44, the short wave ultraviolet (wavelength is between 100 ~ 280nm) that the flame that the burner 12 making short wave ultraviolet sensing component 30 can sense gas oven 11 via monitoring mouth 16 produces sends and send a flame sensing signal; Circuit board 32 to be located in control box 40 and to be electrically connected short wave ultraviolet sensing component 30, in order to be sent by the flame of short wave ultraviolet sensing component 30 sensing signal.
Baffle 50 is the installing port 44 being fixed on control box 40 in the present embodiment; make baffle 50 can correspond to the short wave ultraviolet sensing component 30 of flame sensing apparatus 20 after mounting, and between the monitoring mouth 16 and the short wave ultraviolet sensing component 30 of flame sensing apparatus 20 of casing 14.It should be added that at this, baffle 50 is have high penetration for ultraviolet made by synthetic quartz glass in the present embodiment, and short wave ultraviolet (wavelength is between 100 ~ 280nm) particularly can be allowed to penetrate.
When practical operation, when gas oven 11 is under the state of not opening fire, because short wave ultraviolet sensing component 30 senses less than stove fire, so air exhauster 15 can not be forced to start.Directly gas oven 11 is opened under the situation do not started at air exhauster 15 once user; the short wave ultraviolet that flame can only be allowed to send due to baffle 50 passes through; so the short wave ultraviolet that the stove fire that short wave ultraviolet sensing component 30 can sense gas oven 11 at this moment really sends; and send flame sensing signal to circuit board 32; then this flame sensing signal can be sent to a central processing unit 17 of range hood 13 by circuit board 32, makes central processing unit 17 force start air exhauster 15 operate to carry out smoke evacuation action (as shown in Figure 4).On the other hand; because baffle 50 is blocked between the monitoring mouth 16 of casing 14 and short wave ultraviolet sensing component 30; so baffle 50 can isolating oil soot, dust or other introduced contaminantses touch short wave ultraviolet sensing component 30 simultaneously; in order to provide good protected effect to short wave ultraviolet sensing component 30; until gas oven 11 is at pass fire, central processing unit 17 can control air exhauster 15 because of not receiving flame sensing signal that short wave ultraviolet sensing component 30 sends and shut down.
It should be added that at this, short wave ultraviolet sensing component 30 not necessarily will be arranged in control box 40, can also be exposed to outside control box 40, in addition, baffle 50 also can have different mounting means, as shown in Figures 5 and 6, the present invention also provides the bearing frame 60 made by rubber or flexible plastic, the side mask of bearing frame 60 has two relative snap fits 62, and, bearing frame 60 has an opening 64 and periphery along opening 64 is provided with two pairs of embedding parts 66 and a flange 68, baffle 50 is allowed to be seated on flange 68 between the embedding part 66 first the two ends inlay card of baffle 50 being fixed on bearing frame 60 when assembling, and then be fixed on casing 14 by two snap fits 62 in the monitoring mouth 16 bearing frame 60 being embedded in casing 14, after the installation completing baffle 50, short wave ultraviolet sensing component 30 can sense stove fire through baffle 50, obtain protected effect by baffle 50 simultaneously.
Similarly, also can be as shown in Figures 7 and 8, the surrounding of the monitoring mouth 16 of casing 14 has two relative fixed parts 24, the two ends of each fixed part 24 have one first fixing hole 26 respectively, the periphery of baffle 50 has 4 second fixing holes 52, by four fixture 70(latch as shown in the figure) be arranged between one of them first fixing hole 26 of casing 14 and one of them second fixing hole 52 of baffle 50 respectively, in order to baffle 50 is fixed on casing 14, after the installation completing baffle 50, short wave ultraviolet sensing component 30 also can sense stove fire through baffle 50, obtain protected effect by baffle 50 simultaneously.
In sum, flame sensing apparatus 18 of the present invention senses by short wave ultraviolet sensing component 30 short wave ultraviolet that flame sends, the flame sensor of general quartz burner is used compared to general common infrared fire optical sensor or other, flame sensing apparatus 18 of the present invention has better sensing sensitivity, be not easy to be subject to human body, the interference of sunlight or other external environment factors and reach the object effectively avoiding producing misoperation, and, flame sensing apparatus 18 of the present invention is by the setting of baffle 50, the short wave ultraviolet that flame is sent can pass through smoothly, to guarantee the sensing sensitivity of short wave ultraviolet sensing component 30 pairs of flames further, protected effect can be provided to short wave ultraviolet sensing component 30 again simultaneously, in order to extend the service life of short wave ultraviolet sensing component 30.
