Abstract
The utility model discloses a through-flow impeller which comprises blades and round middle discs, wherein the blades are inserted between two middle discs; each middle disc is provided with an arc slot for inserting the blades; the two ends of the slots are truncation angles; and the two ends of the blades are matched with the truncation angles at the two ends of the slots. In the air conditioner through-flow impeller disclosed by the utility model, the two ends of the slots of the blades on the middle discs are truncated to become truncation angles, and the two ends of the blades are also cut into flat angles matched with the slots; and the condition that the two ends are arc angles is changed, the collision between the blades and the middle discs in the impeller transportation process is avoided, and the strength of the impeller is enhanced so that the impeller is not easily damaged.
Description
Technical field
The utility model belongs to field of household appliances, relates in particular to a kind of air-conditioning through-flow impeller.
Background technique
The tubular wine wheel of the indoor set of at present existing air-conditioning is made up of a section impeller; Impeller is inserted in two circular mid-games by blade and forms; In the wind wheel transportation process, because can making, the collision of jolting can wear and tear between blade and the mid-game, thus the intensity and the working life of having reduced wind wheel.
Summary of the invention
The purpose of the utility model is to provide a kind of simple in structure, fixation, air-conditioning through-flow impeller that intensity is high.
The technological scheme of the utility model: a kind of through-flow impeller; Comprise blade and circular mid-game, blade is inserted between two mid-games, and said mid-game is provided with the circular arc slot that is used for inserting blade; The two ends of slot are the truncation angle, match with the truncation angle at slot two ends in the two ends of said blade.
As preferably, described blade is equally spaced along the mid-game circumference.
As preferably, said mid-game inner ring is provided with a circle stiffening rib.
The air-conditioning through-flow impeller of the utility model is through flat with two end-grain cutting of the blade slot in the mid-game; Become the truncation angle, the straight angle that matches with slot also is cut at the two ends of blade simultaneously, and having changed in the past, two ends all are the situation of arc round angle; Avoided in the impeller transportation process; The intensity of impeller has been strengthened in collision between blade and the mid-game, makes impeller not fragile.
Description of drawings
Fig. 1 is the structural representation of the utility model impeller.
Fig. 2 is the structural representation of the utility model mid-game.
Fig. 3 is the structural representation of blade slot.
Embodiment
Like Fig. 1,2,3, a kind of through-flow impeller comprises blade 2 and circular mid-game 3; Blade 2 is inserted between two mid-games 3; Mid-game 3 is provided with the circular arc slot 4 that is used for inserting blade 2, and the two ends of slot 4 are truncation angle 5, matches with the truncation angle 5 at slot 4 two ends in the two ends of said blade 2.Blade 2 is equally spaced along mid-game 3 circumference.Said mid-game 3 inner rings are provided with a circle stiffening rib 6.
The two ends of the blade slot 4 in the mid-game 3 of impeller change present straight transitions into by original arc transition, form truncation angle 5, and the shape that matches with the truncation angle 5 at slot two ends is processed at the two ends of blade 2; Blade is inserted in the slot 4; Make the two ends and the slot fixation of blade, avoided in the impeller transportation process collision between blade and the mid-game simultaneously; Strengthened the intensity of impeller, made impeller not fragile.Mid-game 3 inner rings are provided with a circle stiffening rib 6, have further improved the intensity of impeller.
