Description
Technical field
The invention belongs to the technical field of range hood, particularly relate to a kind of down-draught type range hood.
Background technology
At present, for getting rid of the range hood of kitchen fume, many based on near-absorption type, tower machine, deep type machine, in these range hoods, blower fan is mostly arranged on above cabinet, is positioned at rear side side or the surface of gas kitchen ranges, whole range hood occupies very big position in the upper sheaf space in kitchen, spatially has constriction, is unfavorable for kitchen overall appearance. In recent years, occur in that the range hood of some downdrafts successively, the blower fan system that generally comprise cabinet, is arranged in cabinet and be vertically arranged on the table top of cabinet, be positioned at the fume collecting chamber on rear side of kitchen range, fume collecting chamber is provided with air inlet, there is in fume collecting chamber the smoke collecting chamber being connected with blower fan system.
In existing down-draught type range hood, for the impurity filtered in entrance blower fan system in oil smoke, reach to filter the purpose of oil droplet, be often provided with one or more layers solid filter net being made up of filament in its air inlet, complete to filter by micropore. But owing to the aperture of mesh is always bigger than the droplet diameter being mingled with in oil smoke many, thus cross the limited in one's ability of filtering fume, and mesh is more little, then mesh periphery more easily gathers greasy dirt and causes mesh and reduce and be even plugged, have a strong impact on the intake of lampblack absorber, thus affecting the total oil smoke of lampblack absorber to get rid of effect. What is more important, these drainage screens are difficult to clean after being stained with greasy dirt, and very it is not tired of to allow user, therefore just can only replace and cause with relatively costly after generally using a period of time.
On the other hand; nowadays; the problem of ecological resources, environmental conservation is increasingly paid attention to by people; national environmental protection department has all formulated emission standard for places such as factory, hotel, restaurants, but, the impact of the environment to external world of oil smoke produced by family cooking also can not be ignored; existing range hood is all the oil smoke that culinary art produces is directly sucked in and is discharged into outdoor; do not carry out purified treatment, the environment of life periphery is caused severe contamination, is unfavorable for environmental conservation.
Summary of the invention
The technical problem to be solved is to provide the down-draught type range hood that a kind of filtering oil smoke is effective and wind loss is few for the present situation of prior art, it can purify discharged oil smoke, it is ensured that the gas being discharged into outdoor meets cooking fume discharge standard requirement.
This invention address that the technical scheme that above-mentioned technical problem adopts is: this down-draught type range hood, including a cabinet, it is arranged on the blower fan system in cabinet and the fume collecting chamber being vertically arranged on cabinet table surface, there is in fume collecting chamber the smoke collecting chamber being connected with blower fan system, it is characterized in that: described fume collecting chamber is tilted is provided with a defecator, this defecator includes at least two-layer screen plate, screen plate has multiple air vent, air vent mutual dislocation on adjacent two layers screen plate is arranged, the periphery of each air vent forms flange, and on all screen plates the direction of the flange of air vent all towards the rear side of fume collecting chamber, and described blower fan system includes blower fan, smoke discharging pipe and a static fume adsorbent equipment, described smoke collecting chamber is connected with the entrance of blower fan, the entrance of described smoke discharging pipe is connected with the outlet of blower fan, the outlet of smoke discharging pipe is connected with the entrance of this static fume adsorbent equipment.
Preferably, described fume collecting chamber can be surrounded by top board, back side panel, left plate, right plate and front side board, being internally formed described smoke collecting chamber, the upper side edge of described defecator is along being connected with the back side panel of fume collecting chamber, and the lower side of defecator is along being connected with the front side board of fume collecting chamber. So, bottom fume collecting chamber without plate just with the opening in communication on cabinet table surface so that smoke collecting chamber is connected with the air intake passage of blower fan system.
For ease of manufacturing, installing, the number of plies of described screen plate is preferably two-layer.
Described air vent both can be circular hole, elliptical aperture, square hole etc., it is also possible to is elongate aperture, but angularly considers from manufacture, air quantity, oil-collecting, it is preferred to strip.
Preferably, on described screen plate, the cross sectional shape of wooden partition between adjacent air vent is curved, and this design is conducive to the smooth outflow of oil smoke, improves air quantity, reduces whirlpool, reduces noise.
Compared with prior art, the present invention adopts bilayer or the double-deck above filter board unit that misplaces in the same direction, by the mode of surface filtration, gas is in motor process, owing to inertial collision is at filter surface, soot gas condensation is made to be attached to filter surface, the obstruction of double-layer filter plate forces air to change direction secondary, thus filter effect is considerably beyond single-layer board type drainage screen, essentially identical with double-deck relative dislocation drainage screen, oil smoke hence into blower fan system is fewer than single-layer board type drainage screen a lot, extends the non-maintaining time of blower fan system.
Meanwhile, making air quantity increase, can utilize again the filtration devices soot gas of air inlet preferably, the path direct transferred by noise due to double-layer filter plate again is blocked, and the noise spread out of is second filial generation wavelet sound, is not the sound that direct transfers, so there being the effect reducing noise.
Therefore, the down-draught type range hood of the present invention can effectively promote fume-exhausting performance, and has good filter effect, effectively extends the non-maintaining time of range hood fan system.
It addition, by arranging static fume adsorbent equipment in the exit of blower fan system, make the oil smoke being discharged into outdoor be fully purified, it is ensured that the gas being discharged into outdoor meets cooking fume discharge standard requirement.
