Abstract
The utility model discloses a multi-point output centrifugal fan, which comprises a volute and a vane wheel arranged in the volute, wherein an air inlet and air outlets are formed in the volute. The multi-point output centrifugal fan is characterized in that: a plurality of air outlets of which the directions are the same as the direction of air flow and which are uniformly distributed at the periphery of the volute are formed in the volume. According to the multi-point output centrifugal fan, the plurality of air outlets are uniformly distributed in the volume along the tangent direction of the external circle of the volume, so that a requirement that a fan uniformly supplies air to different directions or different positions is met; a flow division device, such as an external joint and the like, is not required; during air supply, the air supply resistance is reduced greatly; and the air supply efficiency of the fan is improved.
Description
Technical field
The utility model relates to a kind of centrifugal blower, the centrifugal blower of particularly a kind of multiple spot position output.
Background technique
In the existing technology; Centrifugal blower only is provided with an exhaust outlet; When needs during, a plurality of blower fans need be set or set up with the supporting socket of blower fan and can satisfy demand to different direction or the air-supply of a plurality of position to the air-supply of two or more different direction or a plurality of position.So just caused the increase of cost, and some special occasions, because the restriction in space can't be provided with a plurality of blower fans; Then can influence and produce or use, in addition, socket is set not only to be increased cost and also increases fan resistance greatly; Air quantity is reduced, and air-supply efficient is low.
The model utility content
In order to solve the existing defective of centrifugal blower in the existing technology; The utility model provides a kind of novel multiple spot position output centrifugal blower, and this blower fan has a plurality of exhaust outlets, and this centrifugal blower can be simultaneously to a plurality of directions or the air-supply of a plurality of position; Centrifugal blower air output than single outlet is bigger; And preparation process is simple, has simplified auxiliary facility, has practiced thrift user cost.
A kind of multiple spot position centrifugal blower comprises spiral case and the impeller that places in the spiral case, and said spiral case is provided with intake grill and exhaust outlet, is uniformly distributed with in spiral case cylindrical tangential, said spiral case upper edge and is provided with a plurality of exhaust outlets.
Further, said exhaust outlet is 2-4.
Multiple spot position output centrifugal blower in the utility model is uniformly distributed with in spiral case cylindrical tangential, said spiral case upper edge and is provided with a plurality of exhaust outlets; Use this centrifugal blower can realize the demand of a typhoon machine as different direction or diverse location balanced ventilation; Need not to set up shunting devices such as socket; In the air-supply process, reduce fan resistance greatly, improved the air-supply efficient of blower fan.
Description of drawings
Multiple spot position centrifugal blower structural representation among Fig. 1 embodiment 1;
Multiple spot position centrifugal blower structural representation among Fig. 2 embodiment 2.
Embodiment
Embodiment 1
As shown in Figure 1, output centrifugal blower in multiple spot position comprises spiral case 1 and the impeller (not shown) that is arranged in the spiral case, both sides, spiral case 1 middle part, along impeller axially be provided with intake grill 2, on spiral case 1, also be symmetrically arranged with two exhaust outlets 3.Two exhaust outlets 3 be uniformly distributed with setting along spiral case cylindrical tangential.
As shown in Figure 2, the multiple spot position output centrifugal blower structure among present embodiment and the embodiment 1 is basic identical, and its difference is that at the exhaust outlet that is arranged on spiral case 13 be four, and four exhaust outlets 3 are uniformly distributed with setting along spiral case cylindrical tangential.
Claims (1)
1. a multiple spot position output centrifugal blower comprises spiral case and the impeller that places in the spiral case, and said spiral case is provided with intake grill and exhaust outlet, it is characterized in that, is uniformly distributed with in spiral case cylindrical tangential, said spiral case upper edge and is provided with a plurality of exhaust outlets.
According to the said multiple spot of claim 1 position output centrifugal blower, it is characterized in that 2, said exhaust outlet is 2-4.
