Abstract
The utility model relates to an automatic gas burning range, which is used for the automatic ignition control of a gas burning range. The automatic gas burning range is composed of a burning range frame, a gas valve arranged on the burning range frame, a gas valve switch component which is moved when the gas valve is switched on or off, an ignition controller, a magnet arranged on the gas valve switch component, and one or a plurality of magnetic approach switches arranged beside the motion track of the magnet. The automatic gas burning range can realize the linkage of air supply and ignition control. The automatic gas burning range has the advantages of high reliability of the control system, little operating resistance, gentle hand feeling and simple assembly.
Description
The utility model is the device that is used for the automatic IGNITION CONTROL of combustion gas tool.
Existing Gas Utensil Lighting control device, a kind of is to use the hand turning knob, on the one hand air valve is opened, be contained in cam gear on the air valve stem simultaneously by pressing or decontrol microswitch and press head and make the microswitch action, automatic IGNITION CONTROL is finished in ignition controller work, the ignition control device that has in addition is the pressing knob, air valve is opened, microswitch is moved by pressing and finishes automatic IGNITION CONTROL simultaneously, as number of patent application 87216435 " a kind of gas range igniting and adjusting device " and number of patent application 91201437.7 " gas furnace ignition " etc., these devices all need a mechanical pressing microswitch structure, device that makes rotation become pressing and reset by frame for movement of the needs that have.
Said structure can make the corresponding complexity of machine driving, resistance strengthens, and,, and microswitch contact and contact blow-by, easily cause device action bad because combustion gas tool work under bad environment, Chang Youshui, combustion gas, wet goods pollute because the microswitch contacting travel is short, action gap requires highly.Said structure is single gauge tap formula, can not finish the needs of multinomial control.
Task of the present utility model is to improve existing combustion gas tool control system, makes Iganition control system simple in structure small and exquisite, the reliability height, assembling easily, the operation resistance is little, feel is light, supplies gas, the one step completed automatic gas tool of IGNITION CONTROL device.
The utility model is achieved in that air valve switch spare and the ignition controller that moves when air valve, switch air valve are housed on the burner frame, magnet is housed on air valve switch spare.Magnet proximity switch fixedly is equipped with on track side in magnet movement, and magnet proximity switch electrically connects with ignition controller, and magnet proximity switch can be adorned one or several.When the operator carries out ignition operation according to the mode of operation of used combustion gas tool with rotation, push-and-pull slip or pressing mode, the parts that move during operation---air valve switch spare action, air valve is opened, the magnet that is contained in simultaneously on the air valve switch spare changes with the magnet proximity switch distance, magnet proximity switch is owing to the variation of experiencing magnetic field is moved, ignition controller work is finished automatically supplied gas, the IGNITION CONTROL operation.According to the needs of control, magnet proximity switch can be adorned one or several.
The switch that magnet proximity switch of the present utility model can depend on changes of magnetic field to move with magnetosensitive switch, reed switch, hall-effect switch etc.
Air valve switch spare of the present utility model is meant the parts that are in moving situation in operating process, can be knob, air valve stem, and with the operation of rack-and-pinion drive air valve also can be gear or tooth bar.
Owing to adopt such scheme, supplying gas simultaneously, magnet near or away from magnet proximity switch, make it action, do not increase the operation resistance during switch motion, make this plant automation degree height, operation resistance minor structure is simple.Simultaneously also can be according to the control needs, magnet makes successively at the volley and is contained in the other magnet proximity switch action that needs on the control position of magnet movement track, and switch control can realize diversification.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the vertical section structural map of first embodiment of the present utility model.
Fig. 2 is the structure chart of second embodiment of the present utility model.
In Fig. 1, air valve (2) is contained on the burner frame (1), air valve (2) is a plug valve, it is regulated with air valve stem (3a) on the air valve switch spare (3) and knob (3b), magnet (5) is contained on the magnet cover (7), magnet cover (7) is contained on the air valve switch spare (3), for the ease of assembling, magnet cover (7) can be shaped on one with the identical hole of air valve stem (3a) cross sectional shape, can be with magnet cover (7) by this hole air valve stem (3a) of packing into, and can rotate with air valve stem (3a).
The continuous ignition controller of the available general pulse of ignition controller (4), in order to cooperate the switching system of present embodiment, the pulse firing controller of the band flame detecting pin of work when the delay pulse ignition controller of work or switch disconnected when ignition controller (4) disconnected with switch.
Magnet proximity switch (6) is contained on the burner frame (1), when air valve (2) when closing magnet (5) to be positioned at magnet proximity switch (6) other, magnet (5) is opened with air valve (2) and away from magnet proximity switch (6).
For anti-sealing, combustion gas, wet goods pollute make and break contact, simultaneously for the ease of installing, magnet proximity switch (6) can first fixing seal in switch cover (8), switch cover (8) can be processed a locating hole, switch cover (8) passes through locating hole, be connected on the burner frame (1) with screw (10), switch cover (8) is drawn the same ignition controller of lead (9) (4) and is electrically connected.
Because ignition controller (4) working power generally adopts 1.5V dry cell 1 joint or 2 joints, therefore magnet proximity switch (6) is when selecting active switch such as hall-effect switch for use, to the power requirement height, for reliable in action, magnet proximity switch (6) is selected the reed switch (6) of contact vacuum seal in glass shell for use.
Below the present embodiment course of work is done an explanation: at air valve (2) when closing, magnet (5) is positioned at other its normally opened contact closure that makes of reed switch (6), ignition controller (4) quits work, when carrying out ignition operation, air valve stem (3a) rotates, air valve (2) is opened, magnet (5) is away from reed switch (6) simultaneously, reed switch (6) contact disconnects, ignition controller (4) work, by spray point (11) to burner (12) pulse firing, light combustion gas, through time-delay or after the flame detecting pin detects flare up fire, automatic operation is finished in the discharge of ignition controller (4) stop pulse.
Fig. 1 embodiment scenario-frame is simple, and fitting operation is very convenient, reliable.Owing to adopted the ignition controller of switch disconnection work, made electric current can be low to moderate microampere order by magnet proximity switch.Present embodiment once simulated use 300,000 times in the environment of the many dirt of humidity, this installs, and still reliable operation is errorless.
