Description
Technical field
The utility model relates to a kind of house kitchen central exhaust tubular structure, is specifically related to a kind of gas flow-regulating structure of residential kitchen and toilet exhaust duct.
Background technology
Existing esidential building kitchen exhaust road, be generally and adopt concrete prefabricated property global formation, the fire endurance performance of the concrete prefabricated flue of global formation did not reach 1.0 hours substantially, high due to the kitchen exhaust temperature, greasy dirt is many, this pipeline in use, the accumulation of flue greasy dirt with the passing of time just becomes disaster hidden-trouble, and the thickness of pipe wall of concrete prefabricated smoke vent is generally 1 ~ 1.5cm, its vertical bearing capacity and anti-soft impulse poor performance.In People's Republic of China's construction industry industry standard " house kitchen toilet exhaust passage " (JG/T194-2006), stipulated the standard of house kitchen smoke vent, except will satisfying presentation quality, size and morpheme allowable variation, also explicitly point out vertical bearing capacity and should or not be not less than the 10kg sandbag 1 meter requirement of impacting 5 times highly downwards lower than 1.00h and anti-soft impulse performance less than 90kN, fire endurance.Disclose a kind of formula exhast duct in CN201391074Y, its air draft guidance tape is made with cement mortar, and the fire endurance performance is lower than 1.0 hours, and its inside is empty cylinder, there is no to solve the eddy current air curtain at all and causes the smoke blowing taint of odour problem between floor up and down resident family to show.in CN201531107U, open internal schema fireproof kitchen-toilet smoke vent, this smoke vent is by two housing long slabs, inner membrance and reinforcing rib form, if the ventilating duct of this form of structure is applied to oil-fume of house, if the smog of a large number of users pours in pipeline, under actual service conditions, effect due to smoke exhaust, the static pressure ratio of flue inside is higher, do not have the basic flue gas that solves between the floor resident family of up and down to pour in down a chimney and smoke blowing taint of odour problem, when the air inlet port flue gas enters in flue, the flue gas that meeting and lower floor up arrange meets, two strands of air-flows are met and get along well mutually and are formed eddy current and air curtain, this eddy current and air curtain can hinder the up generation of lower floor's flue gas, in case being clung by greasy dirt, opens when malfunctioning by the air inlet port flap valve, flue gas has an obstruction because of up, just can be to indoor smoke blowing.
In CN1142353C, a kind of pressure swing type exhaust duct structure is disclosed, the gentle rheology pressure part of smoke evacuation guide pipe is set in pipeline, solved the stream swirl phenomenon this structure division, but due to water conservancy diversion in pipeline and component for variable-pressure too much, take up space large, install complicated, easily come off, cause line clogging, can't satisfy user demand fully.
In CN2459389Y, only have a place pressurization, produce and hinder to lower floor's exhaust that makes progress, when solving the air whirl problem, make again lower floor's exhaust produce and hinder, can not satisfy user demand fully.
The utility model content
Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model is to provide a kind of gas flow-regulating structure of residential kitchen and toilet exhaust duct, to realize in the regulation that satisfies national sector standard JG/T194-2006, effectively solve air whirl to obstruction and the flue gas of the up generation of lower floor's flue gas pour in down a chimney, smoke blowing taint of odour problem phenomenon, overcome in the past pipe interior water conservancy diversion and transformation member too much, take up space large, install complicated, easily come off and cause the difficult problem of line clogging, it is had easy to manufacture, easy to assembly, cost is low.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is:
A kind of gas flow-regulating of residential kitchen and toilet exhaust duct structure comprises the exhaust duct unit, intersects deflector and multifunction board; Described intersection deflector and multifunction board intermittently alternately are located in same or different exhaust ducts unit.
Described intersection deflector is intersected by two boards at least and forms, and touches mutually between two boards or does not touch mutually, is obliquely installed along airflow direction in air flue.
Described intersection deflector and multifunction board are located at respectively the access at two ends, same exhaust duct unit.
Described intersection deflector is located at an exhaust duct unit air flow inlet, and described multifunction board is located at another exhaust duct unit air stream outlet, when mounted, and described two adjacent installations in exhaust duct unit.
Described intersection deflector and multifunction board are located at respectively between the access at two ends, same exhaust duct unit.
the gas flow-regulating structure of residential kitchen and toilet exhaust duct of the present utility model, according to the fluid bernoulli equation, utilize varying-voltage principle, produce the transformation exhaust opening by intersecting intermittently of deflector and multifunction board to be arranged alternately in flue, produce at this place and pull out gas effect and negative pressure draft, the accelerated motion that makes progress of guiding flue gas in flue, can effectively eliminate air whirl, air curtain is to the retardance of the up generation of lower floor's flue gas and complete the conversion of dynamic pressure and static pressure at ad-hoc location, making not open the kitchen exhaust mouth place static pressure of smoke exhaust ventilator very little is even negative pressure, form draft and eliminate smoke blowing taint of odour phenomenon.Thereby retardance and the flue gas that can effectively solve air whirl, air curtain pour in down a chimney and smoke blowing taint of odour problem, also overcome simultaneously in the past pipe interior water conservancy diversion and transformation member too much, take up space large, install complicated, easily come off and cause the difficult problem of line clogging.
Described multifunction board has following at least function:
(1) with intersect deflector and coordinate, form a plurality of independently gas flow guidings spaces, this separate space is at least by 4;
(2) stop back flow of gas, play the effect that prevents that upper strata house kitchen air-flow from pouring in down a chimney to lower floor's house kitchen;
(3) strengthen pipeline strength and anti-soft impulse performance;
Beneficial effect: the gas flow-regulating structure of residential kitchen and toilet exhaust duct of the present utility model, simple in structure, adopt the blocking assembly, transportation, installation and use are all very convenient, and the life-span is long, and cost is low, i.e. and environmental protection is economical again.In the requirement of satisfying national construction industry industry standard JG/T194-2006 simultaneously, retardance and the flue gas that can effectively solve again air whirl, air curtain pour in down a chimney and smoke blowing taint of odour problem, also overcome in the past pipe interior water conservancy diversion and transformation member too much, take up space large, install complicated, easily come off and cause the difficult problem of line clogging, have good economic outlook, can produce good social benefit.
