The utility model has the advantages that the unreasonable air pressure distribution is eliminated, the resistance for exhausting cooking fume is reduced, the indoor air purifying ability is increased, and the energy resource is saved.

Description

The split type household smoke exhaust ventilator of ring-type air curtain type

The utility model relates to the device of the cooking flue gas eliminating of a kind of domestic burners or kitchen range.The present primary structure of household smoke exhaust ventilator is the top that the blower fan suction inlet is directly installed on the stove or the kitchen range top, and the direct inspiration of the flue gas that will produce when the negative pressure that produces during work will be cooked is discharged outdoor.The aerodynamic design of this constructional device is unreasonable, and because of the blast irrational distribution is arranged, the result still has the part oil smoke and can not take out outdoor during use, cause detergent power low, simultaneously, the temperature when the unreasonable meeting that blast distributes reduces the cooking stove cooking operation wastes energy.

The purpose of this utility model provide a kind of aerodynamic design rationally, blast has household smoke exhaust ventilator ideal distribution, that detergent power is high.

The utility model household smoke exhaust ventilator adopts the structure of blower fan and range hood split, can improve the power of blower fan like this, and makes room noise excessive can be because of the use high-power blower time.Around smoking machine, form a ring-type air curtain during work of this machine, thereby strengthened the area that purifies.Therefore, under the situation that does not strengthen the smoke exhaust ventilator volume, improved detergent power.

The purpose of this utility model is achieved in that household smoke exhaust ventilator of the present utility model is to be made of centrifugal blower (1), range hood outer case (2), orifice-plate type air distribution plate (3), airduct (4) four parts.Centrifugal blower (1) is that split is settled with range hood outer case (2), be connected with airduct (4) between centrifugal blower (1) and the range hood outer case (2), the bottom surface of range hood outer case (2) is empty, have an exhaust outlet (5) on the end face, orifice-plate type air distribution plate (3) is one or three pyramidal orifice plates of triangle, two right-angle sides of two faces of its triangle cone respectively with range hood outer case (2) in trailing flank firmly be connected, the summit of its triangle cone is connected on range hood outer case (2) top board of range hood exhaust outlet (5) back.Centrifugal blower is set up negative pressuren zone by smoke exhaust pipe at the range hood top, because porose board-like damping air distribution plate effect, make range hood bottom blast all around be lower than the pressure of damp type air distribution intralamellar part, wind speed around the range hood bottom is much higher than the wind speed of air distribution plate like this, has just formed the ring-type air curtain.

The material of orifice-plate type air distribution plate (3) evenly is covered with the plate that diameter is the 1.5-3.0mm through hole for band.Range hood outer case (2) is the rectangular box at the no end, and its end face middle part has the circular row air port (5) that diameter is 120mm.

The advantage that the utility model compared with prior art has is: at first, because the air distribution plate of orifice-plate type is set, promptly adopt damp type blast reallocation technology in range hood, set up ring-type air curtain structure.It is desirable that the aerodynamic design of this structure is reasonable, blast distributes, and cooking flue gas can all be inhaled in the range hood, gets rid of outdoor then.Secondly, because centrifugal blower and range hood are splits, this has just increased the space of range hood, has reduced the resistance during the flue gas discharge is advanced, thereby has improved detergent power, and reduced indoor noise.

The drawing of accompanying drawing is described as follows:

Fig. 1 the utility model totally connects and composes schematic diagram;

The axle of Fig. 2 range hood of the present utility model is looked perspective view;

The elevational cross-sectional view of Fig. 3 range hood of the present utility model;

Cutaway view is looked on the left side of Fig. 4 range hood of the present utility model;

The right view of Fig. 5 range hood of the present utility model;

Below in conjunction with accompanying drawing the utility model is described further.As shown in Figure 1, the utility model is made of centrifugal blower (1), range hood outer case (2), orifice-plate type air distribution plate (3), airduct (4).Centrifugal blower (5) secure placement is outdoor, to not have the rectangular range hood outer case (2) of bottom surface to be installed in the 1200mm eminence of cooking stove top in the kitchen, is that the airduct (4) of 120mm connects the exhaust outlet (5) above the range hood outer case (2) and the air inlet of centrifugal blower (1) with bore.At the porose board-like air distribution plate of the positioned inside of range hood outer case (2) (3) (seeing accompanying drawing 2), it is to be made by plate with holes, and the summit places on the top board of range hood outer case (2) at place, center, exhaust outlet (5) top, rear.After centrifugal blower (1) is opened, oil smoke gas in the kitchen almost all is inhaled in the range hood outer case (2), rise along its wall and orifice-plate type air distribution plate (3), enter airduct (4), finally discharge outdoor by the air outlet of centrifuge (1) by exhaust outlet (5).

Claims (2)

1. split type household smoke exhaust ventilator of ring-type air curtain type, it is made up of centrifugal blower, range hood exhaust outlet, airduct, it is characterized in that: centrifugal blower (1), range hood outer case (2) are that split is settled, two limits of one side, right angle of the orifice-plate type air distribution plate (3) of three triangle cones firmly are connected with a side in the range hood outer case (2), and its vertex of a cone is connected on the top board of range hood outer case (2) of exhaust outlet (5) back of range hood outer case.

2. the split type household smoke exhaust ventilator of ring-type air curtain type as claimed in claim 1 is characterized in that orifice-plate type air distribution plate (3) is made up of three triangle orifice plates, and uniform diameter is the through hole of 1.5-3.0 on the orifice plate.
