Abstract

The utility model relates to an inclined cover type cooking fume removing machine with a new structure for domestic kitchens, which is designed aim at the existing cooking fume removing machine which has poor effect and easily shield the light line and the sight line. The air draft face mask 2 of the shell of the utility model is inclined, and forms an angle alpha of 30 DEG to 60 DEG with the horizontal plane. The structure can cause the mounting position of the inclined cover type cooking fume removing machine to be greatly decreased, having no influence of the operation and no shield of both the light line and the sight line. The distance between the cooker and the centre of a wind inlet of the cooking fume removing machine can be 30 cm, the distance is reduced 50 cm compared with an ordinary cooking fume removing machine. The utility model has good cooking fume removing effect, has little fume outward escape, and is conveniently installed because the utility model also proposes that the back plate 7 of the shell 1 is additionally provided with a back wind outlet.

Description

Inclind cover type cooking fume removing machine

The utility model relates to a kind of household kitchen fume exhausting fan.

Before this, with regard to the various household kitchen fume exhausting fans that people recognized, no matter it has what kind of structure and appearance design, they all have a common characteristic, that is exactly to have the exhausting face shield of a level and have only one to go up exhaust outlet, the exhausting face shield also has some inclinations with very small angles, just is convenient to flowing of Residual oil.This have the fume exhausting fan of horizontal exhausting face shield in order not influence operation and to shut out the light less and sight line as far as possible, its installation site is all higher, generally apart from 80 centimetres of cookers, again because of the financial cost reason, can not select the enough big exhausting face shield of enough big blower fan of exhaust air rate and area for use, therefore the influence of artificial disturbance air-flow very easily causes flue gas to escape when adding crossflow and operation, the result causes fume exhausting fan flue gas trapping rate not high, pump drainage cigarette weak effect.Owing to have only one to go up exhaust outlet, problems such as waste airduct inconvenience can appear installing under many circumstances.

The purpose of this utility model is intended to make improvements according to above-mentioned problems of the prior art, with obtain a kind of under the situation of neither influence operation, the sight line that do not shut out the light few flue gas escape, the pump drainage cigarette is effective, and air draft is provided with fume exhausting fan easily.

For achieving the above object, the technical solution that the utility model proposes is: the exhausting face shield of casing is for horizontal by 30 °～60 ° angle settings, simultaneously at casing by exhaust outlet after setting up on the back plate of wall.

Accompanying drawing is depicted as the utility model structural representation

Below in conjunction with Figure of description and embodiment the utility model is further described: as shown in the figure, casing 1 of the present utility model is designed to right-angled trapezium, the long limit of two parallel edges is that the back plate 7 of casing is fixed by wall, the operating buttons 8 of electric machine control system is housed on the panel of outside, the right-angle side of casing 1 is that top board is horizontal, the hypotenuse of casing 1 is exhausting face shield 2, it is lower on one side by wall, the outside is while being the higher of close people, the angle α of it and horizontal plane is 30 °～60 °, generally select the α angle be 45 ° better.Exhausting blade wheel 9 and the drive motors 10 and the protection net 11 of one group or two groups its axis normal exhausting face shield 2 are installed in casing 1, also are provided with electric machine control system, mozzle 12 and catchment cup 13.End at the exhausting duct 3 on casing 1 top is provided with two outlets, opens on the top board 14 of casing 1 being vertically upward 4, one of exhaust outlets for one and opens on the back plate 7 at casing 1, and level is that exhaust outlet 5, two exhaust outlets in back are equipped with seal cover 6 backward.Two exhaust outlets are set consider that the installation site is different and design that when fume exhausting fan leaned against the exterior wall installation, last exhaust outlet 4 usefulness seal covers 6 blocked, the back exhaust outlet 5 airduct 15 outside mist extractors that run in; When fume exhausting fan leans against that interior wall is installed or exterior wall can't lead directly to the time, back exhaust outlet 5 is blocked, last exhaust outlet 4 connects annex elbow and the outside mist extractor of exhaust duct.

The utility model adopts wide-angle tilt exhausting mask designs, be under the prerequisite that does not influence operation and light sight line, to make the exhausting face shield as much as possible near kitchen range in order to guarantee, experiment shows, when the α angle is 45 °, when the fume exhausting fan horizontal width only is 30 centimetres, its internal structure can be arranged on rational and orderly ground, its installation site can move down significantly, to 30 centimetres of exhausting face shield inlet scoop centre distance cookers, do not influence operation and light sight line fully, at this moment it reduces 50 centimetres than common fume exhausting fan suction inlet for 80 centimetres apart from cooker.Because hot flue gas constantly mixes with surrounding air when rising, the total amount of rising flue gas stream and the diameter of flue gas fluidization tower all increase along with the increase of lifting height, therefore the inlet scoop on the exhausting face shield is good more apart from the near more effect of oil smoke source of the gas, promptly in flue gas column diameter and hour suction of mixed flue gas amount, can accomplish to make the specified pump drainage air quantity of machine to be sufficiently more than the mixed flue gas amount, reduce flue gas and escape, also can reduce power of motor, save power consumption; Simultaneously, because the gas flow rate height in the air entry nearby region can produce a directed flue gas stream that sucks at a high speed thus, can effectively avoid the interference of crossflow and artificial disturbance air-flow, the minimizing flue gas escapes in the kitchen in; The utility model can prevent effectively that also because the inlet scoop is significantly less than people's respiratory tract harmful smoke from sucking.

Claims (1)

1, a kind of oblique hood type fume exhausting fan, comprise the casing that to fix on the wall, one group or two groups exhausting blade wheel and drive motors and protection net that is installed in its axis normal casing exhausting face shield in the casing, electric machine control system, mozzle and catchment cup, be provided with exhausting duct in the casing, there is one to open exhaust outlet on the casing top board in the end of exhausting duct, it is characterized in that: the exhausting face shield (2) of a. casing (1) tilts, it is lower on one side by wall, the outside is while being the higher of close people, the exhausting face shield (2) that tilts is that 30 °～60 ° b. also have an exhaust outlet of opening on casing (1) back plate (7) in the end of exhausting duct (3) with the angle α of horizontal plane, level is back exhaust outlet (5) backward, is equipped with seal cover (6) on two exhaust outlets.
