The present invention is achieved through the following technical solutions: a kind of air conditioner spiral case, inwall molded line on the cross section of air conditioner spiral case comprises: the spiral case curve part that the intake grill circumference along air conditioner spiral case extends, and the position of the exhaust outlet towards air conditioner spiral case of spiral case curve part is provided with opening; First water conservancy diversion curve part, is positioned at the first side of exhaust outlet; Second water conservancy diversion curve part, is positioned at the second side of exhaust outlet; Curved section and at least one straightway is comprised in spiral case curve part.
Further, comprise two straightways be parallel to each other in spiral case curve part, two straightways be parallel to each other are opposed relative to the center of spiral case curve part.
Further, the bearing of trend of two straightways be parallel to each other is perpendicular to the exhaust outlet end face on air conditioner spiral case.
Further, the midplane parallel with the exhaust outlet end face on air conditioner spiral case of spiral case curve part is through two straightways be parallel to each other.
Further, the two ends of straightway and curved section are arc transition.
Further, the length of straightway is greater than 1/2nd of the least radius of spiral case curve part.
Further, the curved section in spiral case curve part extends along spiral of Archimedes or class spiral of Archimedes, and the shape equation of class spiral of Archimedes is with the center of spiral case curve part for the center of circle, R Ψ=R0 (1+C* Ψ); Wherein, R Ψ be inwall molded line on a certain cross section with the distance in the center of circle, R0 is the distance in inwall molded line on the initial cross section of class spiral of Archimedes and the center of circle, and C is constant, and Ψ is the angle in the initial cross section of a certain cross section and class spiral of Archimedes.
Further, what be respectively between 50 ° of < Ψ <, 135 ° and 250 ° < Ψ < 315 ° between the lane place of straightway is part or all of.
Further, the extreme lower position of opening is higher than the center of spiral case curve part
And a kind of air conditioner, has air conditioner spiral case, this air conditioner spiral case is above-mentioned air conditioner spiral case.
By technique scheme, the air channel molded line that air conditioner spiral case of the present invention is new decreases the vortex flow occurred in spiral case both sides, reduces vortex flow noise, makes air-out more smooth and easy, and noise total value reduces; Cabinet air-conditioner small space status requirement can be catered in installation spiral case process, reduce cabinet air-conditioner size, save cost.

Fig. 4 shows the front schematic view of a kind of air conditioner spiral case of the prior art.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
The front schematic view of an air conditioner spiral case of the present invention has been shown in Fig. 1.Inwall molded line on the cross section of air conditioner spiral case 1 comprises, along the spiral case curve part 2 that the intake grill circumference of air conditioner spiral case extends, the position of the exhaust outlet towards air conditioner worm frame of spiral case curve part 2 is provided with opening, and the extreme lower position of opening is higher than the center of spiral case curve part; In the both sides of exhaust outlet, be respectively arranged with the first water conservancy diversion curve part 9 and the second water conservancy diversion curve part 10; And in spiral case curve part, comprise curved section and at least one straightway.Add the inwall molded line of the existing air conditioner spiral case of the special design optimization of straightway, in identical load situation, air channel volume increases, and noise total value reduces.
Preferably, in spiral case curve part 2, comprise two straightways be parallel to each other, be respectively left side straightway 7 and right side straightway 4, two straightways be parallel to each other opposed relative to the center of spiral case curve part 2.Preferably, the bearing of trend of two straightways be parallel to each other is perpendicular to the exhaust outlet end face on described air conditioner spiral case 1.Being set as further for straightway position in the present embodiment, is set as that by parallel straightway position the midplane parallel with the exhaust outlet end face on air conditioner spiral case 1 of spiral case curve part 2 is through two straightways.
See the stereogram of Fig. 2, Fig. 3, arc section 6 and lower arc section 8 on the two ends of left side straightway 7 have respectively, arc section 3 and lower arc section 5 on right side straightway 4 both sides have respectively.The arc section added between these straightways and prototype line carries out transition, forms complete fresh flue.
Preferably, the curved section in spiral case curve part 2 extends along spiral of Archimedes or class spiral of Archimedes, and the length of straightway is greater than 1/2nd of the least radius of spiral of Archimedes or class spiral of Archimedes.Above-mentioned class spiral of Archimedes refers to conventional log spiral; Equilateral base method molded line; Inequilateral base method molded line etc.And the initial cross section of this spiral of Archimedes or the class spiral of Archimedes center line vertical with exhaust outlet end face with spiral case curve part 2 overlaps.
The mathematical relationship of straightway and curved section is as following: the shape equation of class spiral of Archimedes is with the center of spiral case curve part 2 for the center of circle, R Ψ=R0 (1+C* Ψ); Wherein, R Ψ be inwall molded line on a certain cross section with the distance in the center of circle, R0 is the distance in inwall molded line on the initial cross section of class spiral of Archimedes and the center of circle, and C is constant, and Ψ is the angle in the initial cross section of a certain cross section and class spiral of Archimedes.In this formula, what be respectively between 50 ° of < Ψ <, 135 ° and 250 ° < Ψ < 315 ° between the lane place of straightway is part or all of.
According to air conditioner spiral case of the present invention, there is following beneficial effect:
First, new air channel molded line decreases the vortex flow occurred in spiral case both sides, reduces vortex flow noise, makes air-out more smooth and easy, and noise total value reduces.
Secondly, cabinet air-conditioner small space status requirement can be catered in installation spiral case process, reduce cabinet air-conditioner size, save cost.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
