Specific embodiment
The utility model relates to a kind of wind-curtain type household smoke exhaust ventilator, including gas collection petticoat pipe 1, kitchen ventilator shell 2, setting exist Smoke exhaust fan 3, air outlet 4 and circuit and switch control module 9 (part is only shown in figure) in 2 inner cavity of kitchen ventilator shell, stove The surface of tool, which is equipped with, prevents oil smoke from stopping partition by the flue gas escaped above kitchen range, and flue gas stops the outer rim of partition to be equipped with air blast Air duct 5, air blower 6 are connected to air blast air duct 5, the lower surface in the air blast air duct 5 be provided with can make wind in air blast air duct 5 vertically to Under blow the air outlet 51 to form air insulated air curtain.Kitchen range are surrounded by the orthographic projection of air blast air duct 5 in the horizontal plane, the air Isolation air curtain, flue gas stop partition or gas collection petticoat pipe 1 to surround hearth top perspective space, and oil smoke is made to be isolated from the outside, and are formed One relatively independent restricted physical space.The utility model is carried out below in conjunction with Figure of description 1-7 and specific embodiment It is described in detail.
Embodiment 1
As shown in Figs. 1-5, wind-curtain type household smoke exhaust ventilator is top suction type, and the flue gas stops partition to be to be set to kitchen range The gas collection petticoat pipe 1 of surface, the air blast air duct 5 are arranged around the outer rim of gas collection petticoat pipe 1, and air blower 6 passes through adaptation setting Blower export pipe 61 is connected to air blast air duct 5, and the lower surface in air blast air duct 5 is provided with air outlet 51, and the wind in air blast air duct 5 passes through Air outlet 51 is blown out straight down, forms the air insulated air curtain that can enclose kitchen range.Preferably, in air blast air duct 5, air outlet 51 top is equipped with jet stream rectifier 52.Oil removal net 7, when starting smoke exhaust fan, oil smoke is arranged in 1 bottom windward side of gas collection petticoat pipe Enter inside smoke exhaust ventilator from oil removal net 7, by smoke exhaust fan 3, is delivered to air outlet 4, is then discharged into through fume tube public Flue.
In embodiment, the outside of kitchen ventilator shell 2 is equipped with installation air blower cabinet 63, air blower 6 and blower export pipe 61 are arranged in the intracavitary of installation air blower cabinet 63, and air blower cabinet 63 is provided with blower inlet 64.Air blast can not also be set Box body 63, as long as ensuring that air blower 6 and blower export pipe 61 successfully can provide enough positive pressure wind i.e. for air blast air duct 5 It can.Air blower 6 is for one or suitable plurality of, and the blower export pipe 61 is connected to blast orifice 53 with air blast air duct 5 Place, the air blast air duct 5 with blast orifice 53 is starting point, along the outer rim of gas collection petticoat pipe 1, to two sides to each extend over out tail end closed Air blast divides air duct, and two air blast point air ducts enclose gas collection petticoat pipe 1, it is ensured that air blast divides the positive pressure wind in air duct in air blast point In air duct can only one-way flow, do not get muddled.The air blast air duct 5 can also be closed entirety for a head and the tail, with blast orifice 53 Relative to the other end by partition separate at two cavitys.
When the household smoke exhaust ventilator works, gas collection petticoat pipe 1 is as oil smoke air inlet face from the center of gas collection petticoat pipe 1 to surrounding It generates from by force to weak negative pressuren zone, air blower 6 promotes the positive pressure gas flow in air blast air duct 5 perpendicular through jet stream rectifier 52, air outlet 51 It directly shoots down, forms the air insulated air curtain for being centered around 1 outer rim of gas collection petticoat pipe, the air insulated air curtain has adjusted Smoke Machine 3 is formed by the original shape in suction function region under aspirating, and negative pressure is by more efficient utilization.The air insulated air curtain air-flow Leading peak is bent and flows to the center position of gas collection petticoat pipe 1 under the suction function that smoke exhaust fan 3 generates, so that kitchen range generated Oil flue waste gas is dynamically closed in gas collection petticoat pipe 1 is isolated within air curtain with aforementioned air, when oil flue waste gas permeates air insulated It is blocked when the edge of air curtain by downdraught and air insulated air curtain is followed to turn to 1 direction of gas collection petticoat pipe, fundamentally blocked Oil flue waste gas four dissipates the route for diffusing escape, so that all oil flue waste gas is all sucked into gas collection petticoat pipe 1, is finally discharged to outside atmosphere Space will not pollute indoor environment.
Air curtain air pushing hole described in embodiment is rectangle, can also be the shapes common in the art such as circle, slit. The section form in the air blast air duct 5 is unlimited, can be rectangular square tube, round tube or other cross sectional shapes.The smoke exhaust fan 3 For outer rotor blower fan, or the blower commonly used in the prior art such as conventional centrifugal blower, axial flow blower.
Embodiment 2
As shown in fig. 6-7, this specific embodiment 2 is substantially the same manner as Example 1, the difference is that wind-curtain type household is pumped Smoke machine is side-suction type.Wall side is being leaned in the setting of gas collection petticoat pipe 1, and 1 windward side of gas collection petticoat pipe is disposed with the oil removal net 7 of air inlet, upper smoke Vapour lock block breaks as the baffle 10 of the surface of cooking stove is arranged in, and the air blast air duct 5 is mounted on the outer rim of baffle, and kitchen range are roused The orthographic projection of wind air duct 5 in the horizontal plane is surrounded, baffle 10, the gas collection cigarette of the surface of the air insulated air curtain and cooking stove Cover 1 jointly surrounds hearth top perspective space, and oil smoke is made to be isolated from the outside, and it is empty to form a relatively independent restricted physical Between.
The gas collection petticoat pipe 1 can also combine etc. other common forms for top gas gathering mask with side-suction type gas gathering mask.
