Abstract
The utility model discloses a matching structure of a motor fan assembly and a volute, comprising a motor shaft (1), an upper volute (2), an impeller (3) and a first wind stopping ring (4), wherein the upper volute (2) is provided with a second wind stopping device for preventing wind flowing back to a negative pressure area from a high pressure area; the second wind stopping device is specifically arranged on the upper volute (2) and provided with a second wind stopping ring (5) close to the first wind stopping ring (4); the second and first wind stopping rings (5, 4) are arranged coaxially along the axial direction of the motor shaft (1), and the diameter of the second wind stopping ring (5) is greater than that of the first wind stopping ring (4). The matching structure is additionally provided with the second wind stopping ring on the upper volute in the high pressure area, which can better prevent the wind flowing back to the negative pressure area from the high pressure area so as to avoid the noise caused by the back flow and improve the comfortable performance of the whole vehicle.
Description
Technical field
The utility model relates to the car air conditioner field, especially relates to the cooperating structure of a kind of motor ventilating fan assembly and spiral case.
Background technique
Along with the raising of expanding economy and living standards of the people, the automobile huge numbers of families that enter.Along with popularizing of automobile, car air conditioner is being familiar with by people gradually also, and people require also more and more higher to the travelling comfort of car air conditioner, and the noise of car air conditioner is an important indicator examining car air conditioner.
Present motor ventilating fan assembly cooperates the backflow (structure shown in Figure of description 1) of all adopting a ring washer to prevent with spiral case, but the wind that this kind fit system is difficult to thoroughly effectively avoid blower to produce high pressure is back to negative pressuren zone, treat wind to reenter impeller and produce noise, thereby influence the comfort property of automobile.
The model utility content
Technical problem to be solved in the utility model is the cooperating structure that a kind of motor ventilating fan assembly and spiral case are provided at problems of the prior art, its objective is to prevent that wind is back to negative pressuren zone from the zone of high pressure, reduces the car air conditioner noise.
The technical solution of the utility model is the cooperating structure of this kind motor ventilating fan assembly and spiral case, comprises motor shaft, upper volute, impeller and first air baffle ring, is positioned at described upper volute and is provided with and prevents that wind is back to the secondary abat-vent of negative pressuren zone from the zone of high pressure.
Described secondary abat-vent is on upper volute, and is provided with second air baffle ring near the position of first air baffle ring.
Along the axial direction of described motor shaft, second air baffle ring and the coaxial setting of first air baffle ring, and the radius of second air baffle ring is greater than the radius of first air baffle ring.
Having a kind of motor ventilating fan assembly of said structure and the cooperating structure of spiral case has the following advantages:
1, increased by one second air baffle ring above the upper volute of the cooperating structure of this kind motor ventilating fan assembly and spiral case in the high-pressure area, can be good at avoiding the backflow of wind, stoped the wind of zone of high pressure to be back to negative pressuren zone, thereby avoided the noise produce owing to refluxing, improved the comfort property of car load.
2, the cooperating structure of this kind motor ventilating fan assembly and spiral case, it is simple in structure, is easy to realize, and the effect excellence.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the structural representation of second air baffle ring and the first air baffle ring relative position in the utility model.
In Fig. 1-3,1: motor shaft; 2: upper volute; 3: impeller; 4: the first air baffle rings; 5: the second air baffle rings.
Embodiment
Fig. 2 is a structural representation of the present utility model, and Fig. 3 is the structural representation of second air baffle ring and the first air baffle ring relative position in the utility model.By the combination of structure shown in Fig. 2 and 3 as can be known, the cooperating structure of this kind motor ventilating fan assembly and spiral case, comprise motor shaft 1, upper volute 2, impeller 3 and first air baffle ring 4, being positioned at upper volute 2 is provided with and prevents that wind is back to the secondary abat-vent of negative pressuren zone from the zone of high pressure, the secondary abat-vent is specially on upper volute 2, and is provided with second air baffle ring 5 near the position of first air baffle ring 4.Along the axial direction of described motor shaft 1, second air baffle ring 5 and the 4 coaxial settings of first air baffle ring, and the radius of second air baffle ring 5 is greater than the radius of first air baffle ring 4.
The cooperating structure of this kind motor ventilating fan assembly and spiral case is owing to increased by second air baffle ring 5 at upper volute, the on-stream meeting of motor ventilating fan assembly is by the negative pressuren zone air inlet, produce the wind of high pressure in the zone of high pressure, traditional structure is easy to allow the wind of zone of high pressure be back to negative pressuren zone, and after newly-increased second air baffle ring 5 together, under the acting in conjunction of first air baffle ring 4 and second air baffle ring 5, be easy to the wind of most backflow is blocked in the zone of high pressure, so just can avoid refluxing, thereby avoid increasing the noise of car air conditioner.
Claims (3)
