Description
Technical field
The utility model relates to a kind of kitchen ventilation system.
Background technology
Along with expanding economy, resident's housing condition has greatly improved, and dwelling house is built standard also large increase.Because Chinese population is numerous, the soil is in short supply, multilayer and high residential building still will be the principal mode of cities and towns dwelling house in current and quite long from now on period.The oil smoke gas that is produced in order to prevent to cook pollutes indoor environment and is detrimental to health, and fume exhauster for kitchen has obtained using widely.In general, the air pollution source in kitchen mainly is various pernicious gases such as hot gas, oil smoke, and these gases produce when culinary art at any time, and range hood is discharged into these materials in the vertical ventilating system of building one side.
The kitchen ventilation system of existing high residential building has two insoluble problems, one is air current composition, many at present employing mechanical exhausts are mended the wind mode in conjunction with inorganization, the range hood that use in the kitchen in the running will be to outdoor discharge a large amount of waste gas and oil smoke, in air-tightness preferably in the high-rise, can cause the pressure reduction of indoor and outdoor bigger, and when inside and outside differential pressure is excessive, can have influence on the Kai Heguan of door, or cause the refluence phenomenon of semi-hermetic type kitchen range waste gas.Another problem is vertical kitchen ventilation system, i.e. the smoke blowing problem of flue, though vertical flue has the anti-backflow function from draught principle, the actual use still has a large amount of smoke blowings or refluence phenomenon perplexing countless families.
The utility model content
The purpose of this utility model provides a kind of kitchen balanced draught system, solve the technical problem of large quantity of exhaust gas and the frequent smoke blowing of oil smoke in the ventilating system, refluence.
For achieving the above object, the utility model adopts following technical scheme:
A kind of kitchen balanced draught system, comprise range hood, discharge duct and exhaust outlet, described range hood is positioned at directly over the kitchen range, and be fixed on the wall in kitchen, discharge duct is communicated with the outlet flue of range hood, described discharge duct lays to the exterior wall direction along the top board of kitchen and balcony, and be communicated with the exhaust outlet of break-through exterior wall, described discharge duct downstream direction has the 1% downward gradient, the exterior wall of described balcony is also established a wind-supplying mouth, the subsidiary interlock of wind-supplying mouth baffle plate, described exhaust outlet and the wind-supplying mouth spacing in same resident family is at least 0.45 meter, spacing between other resident families is at least 2 meters, and the switch of described range hood is connected with an electrical equipment linkage, and described electrical equipment linkage is connected with the interlock baffle plate switch of wind-supplying mouth by lead.
Described lead and electrical equipment linkage are embedded in the wall in kitchen or are laid in the wall surface in kitchen.
Described discharge duct is metal airduct or PVC-U airduct.
The caliber of described discharge duct is ф 150.
Coated with waterproof material around the junction of described discharge duct and exhaust outlet.
Described discharge duct is surrounded by anti-dewing insulation layer in the pipeline section outside of passing through balcony.
Compared with prior art the utlity model has following characteristics and beneficial effect:
Wind-supplying mouth of the present utility model is installed in the kitchen exterior wall, closes at ordinary times, and it is only just opened by electric-linked device when range hood turns round.When range hood was taken out air, wind-supplying mouth will replenish into fresh air continuously, had guaranteed necessary ventilation volume.Rely on electric-linked device to avoid a large amount of intrusions of outdoor cold air in winter indoor, improve the performance of ventilating of kitchen integral body simultaneously by minimum cost.The cost of whole system is low, and it adopts the horizontal ventilating system, and maximized smoke blowing or the refluence phenomenon of preventing takes place, and improves the drawback of existing rectilinear ventilating system.
The utility model can be widely used in the kitchen ventilation system of premises.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing.
Fig. 1 is the plane of kitchen balanced draught system.
Fig. 2 is the electric-linked schematic diagram of range hood and wind-supplying mouth.
Fig. 3 is the schematic diagram of exhaust outlet and exhaust duct.
Reference numeral: 1-range hood, 2-discharge duct, 3-exhaust outlet, 4-wind-supplying mouth, the electric-linked device of 5-, 6-lead, 7-interlock baffle plate, 8-kitchen, 9-balcony, 10-exterior wall.
The specific embodiment
Referring to shown in Figure 1, a kind of kitchen balanced draught system, comprise range hood 1, discharge duct 2 and exhaust outlet 3, described range hood 1 is positioned at directly over the kitchen range, and be fixed on the wall in kitchen 8, discharge duct 2 is communicated with the outlet flue of range hood, and described discharge duct 2 lays to exterior wall 10 directions along the top board of kitchen and balcony, and be communicated with the exhaust outlet 3 of break-through exterior wall 10, described discharge duct 2 is surrounded by anti-dewing insulation layer in the pipeline section outside of passing through balcony 9.
Described exterior wall 10 is also established a wind-supplying mouth 4, wind-supplying mouth 4 subsidiary interlock baffle plates 7, exhaust outlet and wind-supplying mouth should guarantee certain spacing, avoid the exhaust of part dirt to be sent to indoor once more, described exhaust outlet 3 is at least 0.45 meter with the spacing of wind-supplying mouth 4 in same resident family, and the spacing between other resident families is at least 2 meters.
Referring to shown in Figure 2, the outlet flue of range hood 1 is communicated with discharge duct 2, and the switch of described range hood is connected with an electrical equipment linkage 5, and electrical equipment linkage 5 is connected by the switch of lead 6 with the interlock baffle plate 7 of wind-supplying mouth 4.Described lead 6 and electrical equipment linkage 5 are embedded in the wall in kitchen 8 or are laid in the wall surface in kitchen 8.Outdoor wind-supplying mouth need take measures to prevent the intrusion of dust, pollen, mosquito, mouse etc., should also be noted that simultaneously for the generation that prevents above phenomenon fine and closely woven wire netting being installed is blocked the phenomenon of mesh by dead worm and dust, therefore when design, will consider actual convenience when regularly cleaning and feasible.
