Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings.Below with reference to The embodiment of attached drawing description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings the spiral case 10 of range hood according to an embodiment of the present invention is described in detail.
As shown in Figure 1, the spiral case 10 of range hood according to an embodiment of the present invention may include: outlet coaming plate 1, outlet is enclosed It is provided with separator 2 at plate 1 to form internal orifice 11 and collar extension 12 in 2 two sides of separator, also defines accommodating chamber 3 in spiral case 10, Blower and impeller are arranged in accommodating chamber 3, and accommodating chamber 3 is connected with internal orifice 11, and separator 2 separates accommodating chamber 3 and collar extension 12.It is understood that the main point that the spiral case 10 of range hood according to an embodiment of the present invention is different from traditional spiral case exists In: setting separator 2, the outlet coaming plate of traditional spiral case directly limit the outlet being connected with accommodating chamber, a part of in this way Air quantity can lose at the cavity of outlet.And in the spiral case of the range hood of the embodiment of the present invention 10, it is flowed to out from accommodating chamber 3 The flue gas of mouth coaming plate 1 can flow out under the action of separator 2 from internal orifice 11, without flowing out from collar extension 12, can reduce in this way By the loss for the air quantity that collar extension 12 flows out, so as to sufficiently be promoted under lesser change by simple structural adjustment The overall performance of spiral case 10.In this way under the input of identical motor, spiral case 10 can obtain the output of higher air quantity, wind pressure. In addition, the vortex formed at cavity can also be eliminated in this way, the noise of range hood can be reduced, spiral case 10 can also be extended Outlet diffusion stroke, it is possible to reduce exhanst gas outlet sudden change of flow speed, and can play the role of outlet drainage, reduce outlet Flow losses.
The spiral case 10 of range hood according to an embodiment of the present invention can be changed by simple structural adjustment lesser The dynamic lower overall performance for sufficiently promoting spiral case 10.In this way identical motor input under, spiral case 10 can obtain higher air quantity, The output of wind pressure.
Wherein, there are many arrangement forms of separator 2, the arrangement form of separator 2 is described in detail with reference to the accompanying drawing.
As shown in Figure 1, separator 2 may include: first partition 21, spiral case 10 has a spiral case inlet pressure o, first partition 21 from Accommodating chamber 3 is extending vertically into outlet coaming plate 1 to extend spiral case inlet pressure o.It is understood that extending spiral case inlet pressure by setting The first partition 21 of o can eliminate the vortex formed at cavity, can reduce the noise of range hood, can also extend snail The outlet diffusion stroke of shell 10, it is possible to reduce exhanst gas outlet sudden change of flow speed, and outlet drainage can be played the role of, it reduces out The flow losses of mouth.
Further, as shown in Figure 1, separator 2 may include: second partition 22, spiral case 10 includes: volute tongue 4, second every Plate 22 extends out to the outer edge of outlet coaming plate 1 from volute tongue 4.By the way that second partition 22 is arranged, can eliminate near volute tongue 4 The cavity of generation can reduce the noise of range hood, can also extend the outlet diffusion stroke of spiral case 10, it is possible to reduce flue gas Exit velocity mutation, and outlet drainage can be played the role of, reduce the flow losses of outlet.
Specifically, as shown in Figure 1, first partition 21 and second partition 22 are oppositely arranged, first partition 21, second partition 22 Internal orifice 11 is limited jointly with a part of outlet coaming plate 1, and the outside of first partition 21 and second partition 22 is respectively formed with outer Mouth 12.Certainly, another part of first partition 21 and outlet coaming plate 1 forms a collar extension 12, second partition 22 and outlet coaming plate 1 It is another part formed a collar extension 12.In other words, in spiral case 10 shown in Fig. 1, exporting could be formed with one at coaming plate 1 Internal orifice 11 and two collar extensions 12, can eliminate two cavitys in this way, can be vortexed to avoid generating at cavity, it is possible to reduce outlet Flow losses.
A kind of specific arrangement form of spiral case 10 is described below in detail.
In conjunction with shown in Fig. 2 and Fig. 3, spiral case 10 may include two sub- spiral case 10a of two be oppositely arranged, every sub- spiral case 10a includes subexit coaming plate 1a and sub- separator 2a, and two subexit coaming plate 1a constitute outlet coaming plate 1, two sub- separator 2a Constitute separator 2.The sub- spiral case 10a of two such can be oppositely arranged, so that two subexit coaming plate 1a are constituted out Mouth coaming plate 1, two sub- separator 2a constitute separators 2, and then 10 structure of spiral case can be made simple, and packaging efficiency is high.
Optionally, as shown in Figures 2 and 3, flange 2b is provided on every sub- separator 2a, two flange 2b are suitable for mutual Only support.Flange 2b is respectively arranged on two sub- separator 2a of first partition 21 for example, constituting, two flange 2b phase each other It is right, the correspondence reliability of two sub- separator 2a can be improved in this way, can match in order to the installation between two sub- spiral case 10a It closes, the structural reliability of spiral case 10 can be improved.
Optionally, as shown in Figures 2 and 3, support can be set between every sub- separator 2a and subexit coaming plate 1a Reinforcing rib 2c.For example, can be set between the two sub- separator 2a and corresponding subexit coaming plate 1a of composition second partition 22 There is supporting rib stiffener 2c, two sub- separator 2a due to constituting second partition 22 are obliquely installed, and supporting rib stiffener 2c can have Effect improves the structural reliability of sub- separator 2a, and the connection that can be improved between sub- separator 2a and subexit coaming plate 1a can By property.Preferably, as shown in Figures 2 and 3, supporting rib stiffener 2c can be the stiffening plate being obliquely installed.
Preferably, subexit coaming plate 1a and sub- separator 2a is integrally formed part.For example, every sub- spiral case 10a can be with one Body injection molding, so that sub- spiral case 10a structure is simple, it is at low cost.
Range hood according to an embodiment of the present invention, the spiral case 10 of the range hood including above-described embodiment.
