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: along the spiral case curve part that the intake grill circumference of air conditioner spiral case extends, the position towards the exhaust outlet of air conditioner spiral case of spiral case curve part is provided with opening; The first water conservancy diversion curve part is positioned at the first side of exhaust outlet; The second water conservancy diversion curve part is positioned at the second side of exhaust outlet; Comprise curved section and at least one straightway in the spiral case curve part.
Further, comprise two straightways that are parallel to each other in the spiral case curve part, the center of two relative spiral case curve parts of the straightway that is parallel to each other is opposed.
Further, the bearing of trend of two straightways that are parallel to each other is perpendicular to the exhaust outlet end face on the air conditioner spiral case.
Further, the parallel midplane of the exhaust outlet end face with on the air conditioner spiral case of spiral case curve part passes two straightways that are 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 the spiral case curve part extends along spiral of Archimedes or class spiral of Archimedes, and the shape formula of class spiral of Archimedes is for take the center of spiral case curve part as the center of circle, R Ψ=R0 (1+C* Ψ); Wherein, R Ψ be the inwall molded line on a certain cross section with the distance in the center of circle, R0 is inwall molded line on the initial cross section of class spiral of Archimedes and the distance in the center of circle, C is constant, Ψ is the angle in the initial cross section of a certain cross section and class spiral of Archimedes.
Further, be respectively between the lane place of straightway between 50 °＜Ψ＜135 ° and 250 °＜Ψ＜315 ° partly or entirely.
Further,, the extreme lower position of opening is higher than the center of spiral case curve part
And a kind of air conditioner has the air conditioner spiral case, and 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 has reduced the vortex flow that occurs in the spiral case both sides, reduces the vortex flow noise, makes air-out more smooth and easy, and the noise total value reduces; In the spiral case process is installed, can cater to cabinet air-conditioner small space status requirement, reduce the cabinet air-conditioner size, save cost.
