Description

High-efficiency cooking fume exhauster

The utility model relates to a kind of high-efficiency cooking fume exhauster, belongs to the aeration technology field, is applicable to the workplace that oil smoke distributes, and is specially adapted to family kitchen.

Existing smoke exhaust ventilator, majority do not have the afflux cover, general only in front or both sides smoke blocking board is housed.Also has a kind of smoke exhaust ventilator, its afflux cover is bucket-shaped, air exhauster is installed in the bucket, connection between the afflux cover wallboard of this kind smoke exhaust ventilator is the right angle and connects, thereby inner chamber has the corner angle of many bendings, is commonly referred to air-flow " dead angle ", and flue gas is trapped in " angle of spot hole " in the afflux cover, thereby increase the exhausting resistance, reduced the efficient of air exhauster.On the oil pooling hood inwall, adhere to into grease behind the oil smoke condensation of Zhi Liuing simultaneously, produce oil droplet, pollute.Though another kind of afflux cover is taper, but the junction of its each face of cover wallboard still is above-mentioned " dead angle ", has above-mentioned smoke exhaust ventilator shortcoming equally, simultaneously, the smoke exhaust ventilator of this kind structure is direct oil suction cigarette from the top of cone-shaped hood, will pass through vertical gas pass and horizontal flue through the oil smoke of blade sucking-off, and flue is long like this, increase exhaust resistance, influenced fan efficiency.In addition, because collecting, the oil droplet that the cooling back forms in the vertical gas pass can not thoroughly can pollute along the cover inwall toward dirty equally.Aspect the selecting for use of air exhauster, use the turbine air exhauster at present in the smoke exhaust ventilator mostly, its suction, row's ability, energy consumption is big, and easy cleaning not.

The purpose of this utility model is, overcomes the shortcoming of above-mentioned smoke exhaust ventilator, and a kind of new smoke exhaust ventilator is provided.It is from taper afflux cover lateral surface, rather than from the top smoke pumping; Inhale, exhaust resistance is little; The efficient height; Smoke exhaust pipe is short; Noise is little; It also belongs to simple in structure, cost is low, not the smoke exhaust ventilator that need clean.

The technical solution of the utility model is: it includes the afflux cover, air exhauster, and smoke exhaust pipe; The afflux cover is taper, and its lateral surface is horizontally installed with fixedly smoke exhaust pipe; Air exhauster be installed in this fixedly in the smoke exhaust pipe near the fixing interface of smoke exhaust pipe and afflux cover; Fixedly between smoke exhaust pipe and the afflux cover top, and being connected between the front panel that constitutes the afflux cover and the left and right sides wallboard, be the garden arc connection of smooth transition, air exhauster is an axial fan.

Adopt taper afflux cover, can make the oil smoke gas that enters in the afflux cover do because of flow area dwindles gradually to quicken to flow, such exercising result that quickens to flow, make the inlet scoop of air exhauster produce a negative pressuren zone, thereby the flue gas that produces on the kitchen range top can orientation stably be flow in the afflux cover, and be unlikely to diffusion everywhere.Fixedly smoke exhaust pipe and afflux cover top, and the garden that the is connected to arc light slip that constitutes the wallboard of afflux cover are in order to make flow of flue gas resistance minimum, thereby improve fan efficiency to greatest extent.Smoke exhaust pipe is directly installed on the lateral surface of afflux cover, and air exhauster shortens smoke exhaust pipe length to greatest extent directly at smoke exhaust pipe air entry place, makes the exhaust resistance minimum.

The utility model accompanying drawing and being described as follows:

Fig. 1, front view of the present utility model.

Fig. 2, be the vertical view of Fig. 1.

Fig. 3, be the A one A cutaway view of Fig. 2.

Fig. 4, be the right view of Fig. 1.

The name of respectively numbering institute's counterpart member among the figure is called: 1, afflux cover, 1.1, afflux cover wallboard, 1.2, wallboard garden arc connecting plate, 1.3, pipe and cover garden arc connecting plate, 2, fixing smoke exhaust pipe, 2.1, export, 3, fixed component, 4, air exhauster, 4.1, blade, 4.2, motor, 4.3, the air exhauster fixed support, 5, removable smoke exhaust pipe, 5.1, pipe bend, 6, oil baffle, 7, catchment cup.

By embodiment that accompanying drawing provided this practicality is done novelly to be described as follows further:

Afflux cover of the present utility model (1) is taper, and the cone angle that it is positive is the angle of front wallboard (1.1) and plane, afflux cover inlet scoop vertical line, and this angle is greater than the angle of afflux cover back wall and above-mentioned vertical line.Left and right sides wallboard cone angle is greater than the cone angle of front wallboard, because the inlet scoop of general afflux cover is a rectangle, this rectangle and the kitchen range top adapt, and by operating personnel's direction of standing, left and right directions length is greater than fore-and-aft direction.The degree of depth of afflux cover (1) is the distance from inlet scoop to the top of cover, can be 250 millimeters to 500 millimeters, is generally 300 millimeters.Be horizontally installed with fixedly smoke exhaust pipe (2) on the lateral surface of afflux cover (1), air exhauster (4) comprises blade (4.1), and motor (4.2) is fixed on the fixedly interior interface near smoke exhaust pipe (2) and afflux cover (1) of smoke exhaust pipe (2) by fixed support (4.3).Front panel is connected by garden arc connecting plate (1.2) with left and right wallboard (1.1), its garden arc radius generally can be 40-100 millimeters, it also can not the garden arc plate of single-piece, but directly bend to arc by wallboard, welding then, or whole wallboard (no seam) is used the former once-forming.The top of afflux cover is connected with spherical arc connecting plate (1.3) with the fixing upper tube wall of smoke exhaust pipe (2), is welding between them.Fixedly the lateral surface of smoke exhaust pipe (2) and afflux cover (1) be connected to welding, also can be riveted joint.Fixedly the outlet (2.1) of smoke exhaust pipe (2) is located, can have and can tear imperial removable smoke exhaust pipe (5) open, this smoke exhaust pipe and fixedly the link of smoke exhaust pipe (2) be garden pipe, the port of export is a rectangular tube, elbow is a square elbow.This removable smoke exhaust pipe (5) also can be a conical pipe, no matter is rectangular tube or conical pipe, all is in order to make smoke exhaust pipe outlet bottom surface be higher than the air exhauster import, so that oil flows to catchment cup.The effect of elbow, not only shelves wind exempts to make pouring in down a chimney of wind, also can hinder a grade mosquito, fly enters.The elbow of removable smoke exhaust pipe (5) is to connect together, and can become an integral body.Have on the afflux cover (1) and window or the interconnective fixed component of wall (3), this fixed component also can be the fixation clamp that is fixed on the outer garden of fixing smoke exhaust pipe.Stretching out outdoor removable smoke exhaust pipe can make the oil that drips not drip to other people windowsill.The front of the blade (4.1) of air exhauster (4) is fixed with oil baffle plate (6), and spill port is arranged, and catchment cup (7) is arranged under the spill port.

The utility model is because suction cigarette resistance is little, thereby the power of motor of selected axial fan is little, and only need 40W can be equivalent on the market " bucket type " and the actual effect of automatic smoke exhaust ventilator 105W installed capacity.

Advantage of the present utility model and effect are: the collection oil smoke is thorough, efficient is high, saving Electric energy, noise are little, do not need to clean. When having catchment cup and removable smoke exhaust pipe one end is the garden Pipe exports and is square tube, or be conical pipe, and when making it to produce the inclined plane, then oil droplet is difficult for flowing To outside window and indoor, but flow in the catchment cup. Pollution-free to indoor and outdoor surroundings, cleaning, Health. The utility model also has simple in structure, and cost is low, safeguards, installs, maintains all Technique effect very easily.
