Abstract

The utility model relates to a domestic air cleaning device or a kitchen oil fume cleaning apparatus, particularly a suspension fan type cooking fume exhauster. The utility model is characterized in that the left side and the right side of a machine body (11) are respectively provided with a suspender (1), the ends of the two suspenders (1) are suspended with cross-flow fans (2, 3, 4) in the splayed shape, the casing (4) of each cross-flow fan is in a shape of a clamshell, an air inlet (5) is arranged on the inner side face of each casing (4), and an air outlet (6) is arranged on the top of each casing (4).

Description

Fan suspended formula smoke exhaust ventilator

The utility model relates to a kind of domestic air purification device, a kind of kitchen oil fume purifying device, specifically a kind of fume exhausting fan.

Existing smoke extractor from profile distinguish can be divided into slim, dark cover with the air entry down-stretching.The setting height(from bottom) of smoke exhaust ventilator, it is 65 to 75 centimetres that general requirement begins to the distance of smoke exhaust ventilator from the cooking stove upper limb, if distance too closely can influence the operation of cooker.Because the suction of blower fan is limited, higher apart from cooking stove in addition, so the pump drainage effect of common slim smoke exhaust ventilator is not really desirable, although novel slim smoke exhaust ventilator has increased air curtain, effect is also not obvious.The smoke exhaust ventilator of deep hood type and air entry down-stretching is born in order to improve the pump drainage effect, but its practical effect is still not really desirable.Because the cover mouth of deep hood type also must 65 to 75 centimetres apart from cooking stove, too low influence the cooker operation; And suction inlet down-stretching smoke exhaust ventilator just extends a long and narrow air entry downwards on by the fuselage of wall one side, because the barrier effect of wall, the oil smoke overwhelming majority that can not directly directly be discharged by smoke exhaust ventilator is the oil smoke that eject in pot left and right sides and the outside, so its gettering ability of stretching suction inlet down is also restricted greatly.I am at first to file a kind of excessively " novel air entry down-stretching smoke exhaust ventilator " utility model patent (do not receive as yet and accept notice), the principal character of this utility model is that two, the fuselage left and right sides is provided with flexible suction head downwards, discharge outdoor by the oil smoke that described two suction heads eject the pot left and right sides and the outside, the effect of its pump drainage oil smoke obviously improves than prior art, but the described technical scheme of this utility model must be set up air channel and valve in fuselage, complex structure, the cost height.

In view of there is above-mentioned deficiency in prior art, the purpose of this utility model provides a kind of fan suspended formula smoke exhaust ventilator simple in structure.

The utility model realizes that the technical solution of above-mentioned purpose is as described below:

A kind of fan suspended formula smoke exhaust ventilator, the two, the left and right sides that it is characterized in that fuselage is provided with suspension rod, and the end of two suspension rods is splayed relatively and is hung with cross flow fan, and the casing of this cross flow fan is clam, air inlet is located at the medial surface of casing, and air outlet is located at the top of casing.

The utility model has following outstanding advantage than prior art:

1. the cross flow fan that is hung on the suspension rod is stretched under two of fuselage, just in time drops on the both sides of pot, ejects oil smoke in the pot and takes advantage of a situation and be inhaled into, drain into gas skirt from the air outlet on casing top again in the middle of, efficient height not only, and needed air draught power is low;

2. the relay effect of described cross flow fan, fuselage can increase to 80 to 90 centimetres (effect of mist extractor is unaffected) apart from the height of the kitchen range top, and tall cooker is operated under fuselage and can not met and not discussed.

Below in conjunction with drawings and Examples the utility model is explained in further detail,, grasps better and implement technological means of the present utility model so that the public fully understands technical solution of the present utility model.

Description of drawings:

Fig. 1 and Fig. 2 are the structural representation of a specific embodiment of the utility model, and wherein Fig. 1 is a front view, and Fig. 2 is a left view;

Fig. 3 is the structural representation of cross flow fan described in the utility model;

Fig. 4 is the A--A cutaway view of Fig. 3, and the arrow among the figure is an airflow direction;

Fig. 5 is the user mode figure of embodiment illustrated in figures 1 and 2.

Embodiment:

Referring to Fig. 1, Fig. 2 and Fig. 3, the suspension rod 1 terminal cross flow fan that hangs described in the utility model is made up of the impeller 3 of motor 2 drum-shapes and the casing 4 of clam, and air inlet 5 is located at the medial surface of casing, and air outlet 6 is located at the top of casing 4.Referring to Fig. 3 and Fig. 4, two of the impeller 3 of described drum-shape sealing, air-flow radially traverses along impeller and flows through, and air radially flows into from air inlet 5 during beginning, and radially set air outlet 6 flows out from casing 4 tops then, and the air-flow secondary is by the leaf road.Because the air inlet 5 of described cross flow fan is located at the medial surface of casing 4, air outlet 6 is located at the top of casing 4, so the oil smoke that ejects in the pot is taken advantage of a situation and just is inhaled into, dispatch is discharged outdoor (referring to Fig. 5) again to the fuselage 11 interior main air blower 12 formed high negative districts that are provided with.

Referring to Fig. 1 and Fig. 2, an important additional technical feature of the present utility model is to hang the suspension rod 1 of cross flow fan and the junction of fuselage 11 is respectively equipped with hoisting mechanism.The motor 7 of this hoisting mechanism is located at the top of gas skirt 10, elevator cylinder 8 is located on the output shaft of motor 7, steel wire rope 9 is wrapped on the elevator cylinder 8, and after steel wire rope 9 was walked around pulley 14 on the fairlead 13 that is located on gas skirt 10 sidewalls, two was fixed on the upper end of suspension rod 1.The purpose that the utility model is provided with this additional technical feature is to make suspension rod 1 flexible, when idle cross flow fan is received in the gas skirt 10, avoids taking the space on the kitchen range top.Influence the cooker operation.
