Summary of the invention: technical problem to be solved in the utility model is that a kind of burnt gas wall hanging furnace with the wind flow sensor will be provided; both realized the safety protection function of traditional blast switch effectively; the burning of having avoided the minimizing because of wind flow to cause again effectively is insufficient or because of wind flow too much causes the loss of a large amount of heats, helps energy-conserving and environment-protective.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises wall hanging furnace body, blower fan, gas valve, circuit controller, watertight aircase, combustion chamber, circuit controller and gas valve electrically connect, watertight aircase, combustion chamber, blower fan form the air flow passage in the wall hanging furnace body, it also comprises the wind flow sensor that is contained in the air flow passage, and described wind flow sensor and circuit controller electrically connect.
Described wind flow sensor comprises funnel shaped wind flow sensor housing, gas break-in wheel, magnet rotor, magnet rotor hold-down support, gas break-in tube, output line, Hall element, hold-down support, fluid break-in wheel and magnet rotor are fixed in the fluid break-in tube inner chamber by the magnet rotor hold-down support, fluid break-in tube is connected in the wind flow sensor shell intracoelomic cavity, and Hall element is fixed on the flow sensor housing.
Described wind flow sensor is installed in the air air inlet place of watertight aircase in the air flow passage or the exhaust opening place of blower fan.
Described wind flow sensor is fixed on the air air inlet place of watertight aircase or the exhaust opening place of blower fan by screw.
Described fluid break-in tube is provided with bayonet socket, has draw-in groove in the inner chamber of wind flow sensor housing, in the inner chamber that is fixed on wind flow sensing gas housing of fluid break-in tube by bayonet socket and draw-in groove.
The utility model is compared the beneficial effect that is produced with prior art: because the utility model adopts the wind flow sensor in the air duct of burnt gas wall hanging furnace, can how much come the closure and the disconnection of gauge tap according to detected air mass flow, realize safety protection function; Simultaneously can also carry out ratio to combustion gas effectively and regulate, the burning of avoiding the minimizing owing to air capacity to cause is insufficient, also can too much not cause the loss of a large amount of heats because of air capacity, helps energy-conserving and environment-protective.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structure enlarged diagram of Fig. 1 apoplexy flow sensor 3.
Fig. 3 is an A-A section enlarged diagram among Fig. 2
The specific embodiment: shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, this example comprises wall hanging furnace main body 1, blower fan 2, gas valve 4, circuit controller 5, watertight aircase 6, combustion chamber 8, wind flow sensor 3.
As Fig. 2, wind flow sensor 3 shown in 3, it comprises funnel shaped wind flow sensor housing 9, gas break-in wheel 10, magnet rotor 11, magnet rotor hold-down support 12, gas break-in tube 13, output line 7, Hall element 14, hold-down support 15, fluid break-in tube 13 is provided with bayonet socket, have draw-in groove in the inner chamber of wind flow sensor housing 9, in the inner chamber that is fixed on wind flow sensor housing 9 of fluid break-in tube 13 by bayonet socket and draw-in groove, fluid break-in wheel 10 is fixed in fluid break-in tube 13 inner chambers by magnet rotor hold-down support 12 with magnet rotor 11, and Hall element 14 is fixed on the flow sensor housing 9 by screw.
The mounting means of wind flow sensor 3 is: the hold-down support 15 of wind flow sensor 3 is fixed on the watertight aircase 6 air inlet places or the blower fan 2 exhaust outlet places of air flow passage by screw with wind flow sensor 3, and wind flow sensor 3 is realized electrically connecting of wind flow sensors 3 and circuit controller 5 by output line 7.
The operation principle of wind flow sensor 3 is: when air is flowed through wind flow sensor 3, at first air-flow enters in the air-flow break-in tube 13 along funnel shaped wind flow sensor housing 9, can slowly increase along the process gas flow rate that infundibulate housing 9 enters into air-flow break-in tube 13 at gas, when the break-in of gas gas coming through takes turns 10, air-flow becomes vortical flow, promoting magnet rotor 11 then rotates, be riveted on Hall element 14 on the wind flow sensor housing 9 and sense the variation in magnetic field, and produce the consecutive pulses frequency signal according to the variation of magnetic field intensity, export circuit controller 5 to by output line 7 then.
The implementation process of Fig. 1 is: connect power supply, start the wall hanging stove, whether the condition of work that circuit controller 5 at first detects wall hanging stove water circuit system is normal, if it is working properly, blower fan 2 entrys into service, produce negative pressure in the watertight aircase 6, the air in the external environment condition enters into watertight aircase 6 from watertight aircase 6 air inlets and enters 8 inside, combustion chamber again.Flow through when air enters watertight aircase 6 flow sensor 3 at the air air inlet place that is contained in watertight aircase 6, to have sensed air communication out-of-date when wind flow sensor 3, air-flow can promote magnet rotor 11 rotations in the flow sensor 3, variation according to wind flow, wind flow sensor 3 transmits the consecutive pulses frequency signal for circuit controller 5 by output line 7, circuit controller 5 is adjusted the size of gas valve 4 air inflows again according to the power of receiving signal, thereby eliminate the defective that the burning that causes inadequately owing to air capacity too much heat insufficient or that too much cause because of air capacity runs off, realize the effect of energy-conserving and environment-protective.
When blocking appearred in smoke evacuation system, the magnet rotor 11 that does not have air-flow to promote in the wind flow sensor 3 rotated, and at this moment circuit controller 5 can't accept signal, just can cut off the air feed of gas valve 4, realizes the function of safeguard protection.
