Description
Technical field
The present invention relates to a kind of kitchen purification equipment, specifically relate to a kind of kitchen discharged lampblack pipe intelligent electric check valve.
Background technique
Air outlet for kitchen ventilator and common flue enter the registered permanent residence and are generally provided with check valve, but use and oil smoke can occur after a period of time and pour in down a chimney; And not smooth with smoke evacuation, its reason mainly comprises the following aspects:
Reason one: the check valve on range hood and the independent oil smoke check valve sold add shock mount with except helping valve closing except fraction on valve block, mostly opens by range hood wind-force, structure that valve block deadweight is closed.In order to ensure that range hood wind-force can open check valve, valve block weight or spring force can not be excessive, which limits the power of throttle down, but the valve block under this occasion is subject to grease adhesion is the inevitable fact.The Push And Release of the valve block check valve after adhesion is all not in place, and its consequence is that the smooth and oil smoke of air draft pours in down a chimney.
Reason two: for reducing grease adhesion, ensure that the strong wind power of range hood is to blow valve block open, a circumferential weld arranged by the check valve of overwhelming majority range hood between valve block and valve body, to reduce the area of contact of valve block and valve body, when neighbours open range hood (blowdown) and in common duct, local compression increases, such circumferential weld is exactly the circumferential weld that flue gas pours in down a chimney.
Reason three: the newly-built building of national regulation adopts major and minor formula common flue, the auxillary flue be connected with range hood during to utilize main wind passage wind speed is to a certain extent in negative pressure state, prevents oil smoke and pours in down a chimney.But can produce excessive negative pressure when air quantity is excessive in flue and inhale opening check valve valve block, inhale the valve block after opening as then can not effectively closed by grease adhesion, when main flue channel pressure reduces, auxillary flue negative pressure disappears, and oil smoke occurs and pours in down a chimney.NBS cigarette fan delivery is 7 cubes ms/min, and the cigarette machine being greater than now 14 cubes ms/min is very general, and resident family also misses potter Wind Volume cigarette machine of buying, and flue be can't bear the heavy load more, and oil smoke pours in down a chimney and takes place frequently.In addition because the air force in flue is determined by amount of starting shooting simultaneously, happen occasionally so oil smoke pours in down a chimney.
Reason four: when upstairs kitchen ventilator smoke evacuation pressure and air quantity larger time can produce air curtain effect, make downstairs in flue local compression increase, the dirty gas that local compression increases in rear promotion flue leaks from the check valve that sealing effect is bad, and this is the reason of pouring in down a chimney downstairs of upstairs cooking.
Reason five: although existing novel electric check valve rotates by motor, but the clockwise and anticlockwise of the motor that the rotation controlling motor just relies on simple circuit or position limit switch to control, lack the measuring ability of self, strong and weak electricity isolation features, anti-interference function and fault alarm function, these defects all bring hidden danger to the safety of user.
To discharge fume not smooth reason: the grease be accumulated on check valve adds valve block weight, after valve block adding shock mount, resistance opened by check valve increases, and fume-exhausting confidential consumption part air quantity overcomes these resistances; The check valve being particularly arranged on common flue mouth is all bottom-open types, and valve block can not be opened to put in place and reduce ventilation section, and these all will cause exhaust air rate to decay, and discharges fume not smooth.Or occurring that valve block clings causes the air draft of kitchen ventilator to be blown not open, oil smoke row do not go out.
Based on above-mentioned background, the invention provides a kind of intelligent electric check valve, depend merely on ball bearing made or position limit switch from traditional to control the design that motor rotates different, the present invention controls motor forward/backward rotation in real time by intelligent control chip and two microswitch sensors, electronic function is made to overcome the attraction force of magnetic gasket and grease stiction force accurately drives check valve sheet to be opened to phase difference 90 °, thoroughly solve the valve block of the check valve of conventional belt motor owing to gambling then the problem of not opening or can not open completely, and kept the airtight of air channel by the principle that magnetic gasket attracts when non-return valve block closed condition all the time in conjunction with the self-locking of motor and valve block, negative pressure is prevented to open, that unique intelligent control chip and microswitch sensor of adopting controls motor unlatching in real time at present, and the check valve of the two-way closedown of valve block is attracted in conjunction with magnetic gasket.
