Description

Dicyclo groove bucket type smoke exhaust ventilator

The utility model relates to a kind of dicyclo groove bucket type smoke exhaust ventilator.

At present, known smoke exhaust ventilator is by drawer-like housing, discharge pipe, is equipped with the oil smoke retaining shrouding of list or diplopore filter screen and is located at the horizontal exhaust fan in the housing, external swab case etc. and constitute, the energy smoke pumping, but its complex structure cost height, greasy dirt easily is stained with and is bonded on ventilation fan, filter screen and the oil smoke retaining shrouding, very easily form to hang and drip, the mist extractor effect is not ideal.

For addressing this problem, common way is that housing is designed to dark bucket type, and ventilation fan is flat in the blast pipe of dark bucket top, and dark bucket is established an annular oil groove with the blast pipe junction.Chinese patent CN2147451N disclosed " bell-type smoke exhaust ", can reduce cost, reduce greasy dirt be stained with sticking, increase the mist extractor effect, but since the exhaust fan level of this smoke exhaust down, equally with dark bucket flared horn perisporium still can be stained with sticking greasy dirt, fail to resolve to hang and drip a pollution problem.

The purpose of this utility model is that a kind of improved dicyclo groove bucket type smoke exhaust ventilator will be provided, and it can prevent to be stained with sticking greasy dirt extension effectively and drip.

The purpose of this utility model realizes like this:

Adopting the air outlet seat to have is the bucket cover of falling the bucket shape of annular oil groove, is provided with annular oil groove down in bucket cover flared horn lower edge, and the interior angle wall of bucket cover is provided with the leak oil line that overlap joint is gone up annular oil groove and following annular oil groove, and exhaust fan and filter screen are inclined in the blast pipe of bucket cover top.

There is the one side of bar switch, illuminating lamp, gas sensitive devices that the sealing of conformal internal partition is arranged in the bucket cover.

The utility model will be gone up the annular oil groove water conservancy diversion because only need establish annular oil groove in former bucket cover flared horn with interior angle wall leak oil line, flow in two oil grooves and will not hang droplet so be stained with the greasy dirt that sticks in bucket cover and the blast pipe; Simultaneously, hang in the last annular oil groove that flow under flowing to behind the blast pipe sidewall in the bucket cover air outlet seat along the inclination angle so be stained with sticking greasy dirt on it because exhaust fan tilts to install in blast pipe and is provided with filter screen; In addition because the starting point does not lie in the structure that changes the bucket cover of falling the bucket type, keep still that cost of manufacture is low, oil smoke air-flow easy to change speed is escaped into etc. characteristics.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the main cross-sectional schematic according to the dicyclo groove bucket type smoke exhaust ventilator that the utility model proposes.

Fig. 2 looks schematic diagram according to the left side of the dicyclo groove bucket type smoke exhaust ventilator that the utility model proposes.

Fig. 3 is the elevational schematic view according to the dicyclo groove bucket type smoke exhaust ventilator that the utility model proposes.

Describe details and working condition in detail below in conjunction with Fig. 1 to Fig. 3 according to the concrete smoke exhaust ventilator that the utility model proposes.

As shown in Figure 1, this smoke exhaust ventilator comprises the exhaust fan [1] and filter screen [3] that places in the blast pipe [2], and the flared horn lower edge that is provided with annular oil groove [13] bucket cover [5] in the air outlet seat [4] of bucket cover [5] is provided with down annular oil groove [7]; The interior angle wall is provided with to connect and goes up annular oil groove [13] end and stretch to the leak oil line [11] of annular oil groove [7] down; The flared horn of bucket cover [5] is a flat side, simultaneously is equipped with the one side that swab case [10], front be equipped with bar switch [8] electric elements of etc.ing by wall inwardly and seals with internal partition [6], and internal partition [6] offers illuminating lamp [9].As shown in Figure 2, the flat side that bucket cover [5] is provided with bar switch [8] outwardly is provided with also that gas is in bulk puts [14], towards two swab cases [10] butt joint that the is built-in with oil leaking hole of annular oil groove [7] down; After discharge pipe [2] is inserted in bucket cover [5] air outlet seat [4], tighten with dead ring [12].As shown in Figure 3, internal partition [6] is hidden in one side with illuminating lamp electric elements such as [9], is convenient to cleaning; The leak oil line of interior angle wall [11] can will be gone up the interior long-pending oily earial drainage of annular oil groove [13] annular oil groove [7] extremely down, and the long-pending oil of following annular oil groove [7] then flows in the swab case [10].During work, the power selection key of pressing bar switch [8] can start exhaust fan [1] and rotate, cause escape pipe [2] and the interior negative pressure of bucket cover [5], make and cook the oil smoke even air outlet seat [4] of pouring into post in large-scale flared horn that produces, also exclusive from exhaust fan [1] break-through after filter screen [3] filters.Greasy dirt at exhaust fan [1], the long-pending knot of filter screen [3] flow to annular oil groove [13] because of it is tilting along discharge pipe [2] madial wall; Needing to open illuminating lamp [9] or gas sensitive devices [14] or shutdown all upward operates on the corresponding button at bar switch [8].During making, following annular oil groove [7] can remove preceding, left and right groove, only keeps pit and detachable the cleaning, establishes a leak oil line [11] at least and also has effect same; The outward appearance body of bucket cover [5] is made can variation, as makes dome rectangular, circle rectangular tube elbow type, rectangular opening two joint wapperijaws lid bucket types, cambered surface pipe and connect arc formula, square opening curved surface square cover type, the only angular length side of circle bucket type, the curved formula etc. of covering of fillet straight flange.
