Background technology
At present, the technology of the switch of existing mist extractor blower fan and the interlock of the ignition switch of gas-cooker is open, more employing contact switch control blower fan; Simple control can not make mist extractor blower fan and gas-cooker reach best duty, and there is the risk of exploding in big current contact control mode when gas leakage appears in the pipe joint of built-in type cooker; Some adopts infrared ray, thermocouple sensor to detect that flare then seems complicated, cost is high; Also damage easily, the height that the cost of maintenance is also suitable, some detects the oil smoke situation through temperature sensor or Smoke Sensor are set on the smoke exhaust; Owing to usually can be stained with oil on the sensor; Keep away unavoidably and will often safeguard, also stand-by power consumption must be arranged, waste energy.
Notification number CN 201074863Y; The intelligent linkage control device of kitchen range and range hood is disclosed; This control device is provided with firepower subregion circuit board; This circuit board is divided into moderate heat, big fire and little fiery three conduction regions with the rotation semicircle of kitchen range firepower adjusting knob, and the rotating shaft of firepower adjusting knob is provided with the slide plate switch, and slide plate switch ends and conduction region join.
Though this invention can detect the segmentation firepower signal of telecommunication, can not gather with the firepower size continually varying signal of telecommunication, be equivalent to adorn the third gear position sensor, employing be that the contact technical scheme is arranged, have the life problems of mechanical wear.
Notification number CN 202140676U discloses a kind of gas valve that can detect any rotational angle of valve rod, includes valve body; Valve rod; End cap is installed; The microswitch assembly; The microswitch depression bar; It is characterized in that: also be equipped with on the described valve rod and can export the sensor device of this valve rod with respect to the rotational angle signal of telecommunication of said installation end cap.Described sensor device includes the resistance switch that circumferentially is provided with along said valve rod and the driving lever that can be all the time electrically contacts with said resistance switch, and said resistance switch is fixedly connected on said installation end and covers, and said driving lever is fixedly connected on the said valve rod.
In the prior art; The kind of angular sensor is a lot, and the rotary encoder formula of optics, induction, coil induction type, condenser type are arranged, also have potentiometer formula, resistance-type or the like, but the anglec of rotation of how to gather testee; Different angular sensors then has different certain aspects; The mechanically connection of testee and angular sensor is also because of type of sensor is different and different, and according to the disclosed content of this utility model, this technical scheme is that the form through potentiometer formula and resistance-type obtains the anglec of rotation; What adopt also is that the contact technical scheme is arranged; The life problems that has mechanical wear, in addition, the knob of existing gas range igniter rotates 90 degree from 0 degree and forwards 180 again to when spending; Firepower is regulated from little fire to big fire and is provided with to little fire, how this resistance is converted to regulate this utility model that is complementary also unexposed with firepower this moment.
Summary of the invention
The present invention is according to above deficiency; Provide a kind of contactless synchronous output firepower to regulate the gas-cooker of the signal of telecommunication; This signal of telecommunication can be complementary to the setting of little fire from little fire to big fire with the heat power of gas burner adjusting again, can be used for controlling late-class circuit such as controller, final control apparatus such as ventilating fan etc.
Technical scheme of the present invention is:
A kind of contactless synchronous output firepower is regulated the gas-cooker of the signal of telecommunication; The igniter that comprises gas-cooker; The rotating shaft of said igniter is provided with the shake-up parts; It is characterized in that: the termination of these shake-up parts is equipped with the magnetic material that is provided with along the rotating shaft peripheral direction, and described magnetic material is a circular arc body, is arranged on the corresponding fixed position with the supporting Hall element of this magnetic material.
Select for use Hall element be since this sensor can be contactless, continuous the collection signal; Long service life; Safety coefficient is high, and the position that Hall element is fixed can be the fixed mount on the igniter, also can be the fixed position of fixed ignition device on the gas-cooker.
As preferably; Described circular arc body end face is perpendicular to described rotating shaft setting; The symmetry axis of this circular arc body is through the rotating shaft axle center; And the radius that described circular arc body rotates with said rotating shaft is not equal to the radius of this circular arc body periphery, and this circular arc body rotates with said rotating shaft and forms a circular arc body track, described Hall element be arranged on this circular arc body track maximum radius position or least radius position near.
Said circular arc body end face is meant two faces that circular arc body is parallel.Through this technical scheme, when circular arc body rotates, the distance of this circular arc body and Hall element can take place arrive more from the near to the remote near variation or by as far as closely again to variation far away, arrive little signal from small to large again thereby can collect firepower.
Preferred as another kind; It is on the position of radius of turn of center rotation with the rotating shaft near it that described circular arc body is arranged on this circular arc body radius; And the symmetry axis of circular arc body tilts with respect to two terminations of this circular arc body downward or upward; This circular arc body rotates with said rotating shaft and forms a circular arc body track, and described Hall element is arranged near the end face or bottom surface of this circular arc body track.
