Description
Technical field
The present invention relates to integrated kitchen range fireproof device of flue field, especially side-draft integrated stove fireproof device of flue.
Background technology
At present, integrated kitchen range is in use because of when in pot there is phenomenon on fire in pot in high oil temperature, and flame can be sucked flue by oil smoke emission system, ignites electricity piece in grease in flue and integrated kitchen range, causes integrated kitchen range to be damaged.More seriously, the flame that ignite in integrated kitchen range can be diffused into other cooking apparatus by exhaust duct, causes fire, there is larger potential safety hazard.
In existing integrated kitchen range product technical solution, part adopts flame ion induction mode, namely arrange flame ion inductive needle at inlet scoop place, stove chamber and controlled by sensor circuit, shut electromagnetic valve and blower fan when ion inductive needle detects flame, to avoid propagation of flame; Indivedual manufacturer adopts the control method giving wind duct temperature setting point, the temperature sensor be arranged in air channel can detect flue-gas temperature, suck in company with flue gas if any flame, flue-gas temperature can rise, shut electromagnetic valve and blower fan when flue-gas temperature reaches set point.The former is comparatively large by such environmental effects, as oily wastewater pollution flame inductive needle, profit condensate liquid cause inductive needle ground short circuit etc., wrong report or failure frequently occurs when reality uses; Whether the flue-gas temperature value detected is sucked the criterion of flame by the latter in integrated kitchen range machine, without wrong report phenomenon, but have ignored the influence factors such as environment for use temperature, the control system response time is longer, integrated kitchen range still exists that to close blower fan and fuel gas path cause be sucked the phenomenon that more flame ignites, and can not eliminate safe hidden trouble completely.
Summary of the invention
For overcoming deficiency and the shortcoming of existing integrated kitchen range, integrated kitchen range fireproof device of flue provided by the invention, to be inhaled into flue gas temperature rise rate in flue for parameter, shortens the control system response time, hidden danger on fire in elimination machine, reaches the object that it improves.
The technical solution adopted in the present invention is achieved in that integrated kitchen range fireproof device of flue, comprises and being made up of temperature sensor, spiral case, plug valve, gas header pipe, magnetic valve, impeller, motor, flue, gas inlet pipe, smoke exhaust pipe and controller etc.Wherein, temperature sensor is fixed on the position of flue near flue gas suction inlet, flue is connected with the air inlet of spiral case, and motor is fixed on spiral case, and impeller is fixed in the rotating shaft of motor, one end of smoke exhaust pipe is connected with the air outlet of spiral case, the other end of smoke exhaust pipe is the flue gas discharge opening be connected with common flue, and one end of magnetic valve is connected with gas inlet pipe, and the other end of magnetic valve is connected with gas header pipe, gas header pipe is communicated with plug valve, and temperature sensor, magnetic valve are electrically connected with controller.The other end of plug valve is connected to gas-distributing pipe.
Described temperature sensor is fixed on flue, and the position of the flue gas suction inlet of close flue.
Described magnetic valve can be connected on combustion gas input channel, also can be connected on plug valve.
Described controller, does not affect by system-operating environment temperature as the governing factor shortening system response time with the temperature rise rate of flue gas in flue
Under duty, temperature sensor detects the temperature value of the flue gas be inhaled in flue in real time, and feeds back to controller, by controller compare calculate air channel suck the temperature rise rate of flue gas.Under normal operating conditions, in flue, the temperature rise rate of flue gas is lower than setting value; When under unexpected state, flame is inhaled into flue, in flue, the temperature rise rate of flue gas increases, when temperature rise rate reaches setting value, controller output signal is disable motor and magnetic valve immediately, close combustion gas input channel while preventing flame from being continued to suck flue with flue gas, eliminate the potential safety hazard that integrated kitchen range is on fire.
The present invention has following substantive distinguishing features and progress relative to prior art.
1, prevent flame from sucking integrated kitchen range flue and common flue, improving product security performance, eliminates safe hidden trouble.
2, do not affect by environment for use temperature, control system fast response time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is valve of the present invention and gas pipeline connection diagram.
Fig. 3 is electrical connection block diagram of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
See accompanying drawing 1 and Fig. 2, integrated kitchen range fireproof device of flue is by temperature sensor (1), spiral case (2), plug valve (3), gas header pipe (4), magnetic valve (5), impeller (6), motor (7), flue (8), gas inlet pipe (9), smoke exhaust pipe (10) and controller (11) composition, temperature sensor (1) is fixed on the position of flue (8) near flue gas suction inlet, flue (8) is connected with the air inlet of spiral case (2), motor (7) is fixed on spiral case (2), impeller (6) is fixed in the rotating shaft of motor (7), one end of smoke exhaust pipe (10) is connected with the air outlet of spiral case (2), the other end of smoke exhaust pipe (10) is the flue gas discharge opening be connected with common flue, the inlet end of magnetic valve (5) is connected with gas inlet pipe (9), the outlet side of magnetic valve (5) is connected with gas header pipe (4), gas header pipe (4) is communicated with plug valve (3).The other end of plug valve is connected to gas-distributing pipe.
Accompanying drawing 3 is shown in electrical connection, and temperature sensor (1), magnetic valve (5) are electrically connected with controller (11).
Under duty, the flue temperature value detected in real time is fed back to controller by temperature sensor, and the flue-gas temperature in the flue that controller detects different time point compares, and calculates the flue gas temperature rise rate in flue in real time.Under normal operating conditions, flue gas temperature rise rate in flue is lower than setting value, when flame is surprisingly sucked flue, in flue, flue gas temperature rise rate increases, when temperature rise rate increases to setting value, disable motor and magnetic valve immediately, thus prevent flame to be inhaled into flue, eliminate the potential safety hazard that integrated kitchen range flue is on fire.
