Abstract
The utility model discloses a hanging air conditioner with multi-section cross flow fan blades, wherein the single cross flow fan blades are modified into multi-section cross flow fan blades and a support mechanism of the cross flow fan blades is additionally provided with the shortening of the distance between supporting points. The cross flow fan blades of each section are connected through a fastening screw in a coaxial series connection mode, so that the multi-section cross flow fan blades are in synchronous rotation. The support mechanism comprises a bearing seat support and the bearing seat support is slidebaly connected with the bottom shell of the hanging air conditioner. At the same time, a guide structure is arranged on a corresponded position of an outlet of the fan to facilitate the smoothness of airflow. Under the premise that the air output and the operation noise level of the hanging air conditioner and a hanging air conditioner with the use of a single cross flow blades fan are equivalent, the length of the cross flow fan blade of the utility model is substantially reduced, thus the secular distortion is reduced and the stability of the air conditioner performance is improved as well.

Summary of the invention
The purpose of this utility model is, do not changing blower fan length, guarantees again under the constant prerequisite of air quantity and noise, eliminates through-flow fan blade and can have the high-temperature aging problem on deformation, improves the stability of household air-conditioner; The air-conditining of same specification can adopt the through-flow fan blade of different numbers, different length, and only needs this bearing bracket of translation, can realize the support to through-flow fan blade.
Air-conditining described in the utility model is achieved in that and makes single through-flow fan blade into the multistage through-flow fan blade, increases the supporting mechanism of through-flow fan blade, shortens the distance of the strong point.
Air-conditining with multistage through-flow fan blade of the present utility model comprises through-flow fan blade and supporting mechanism, wherein:
Described through-flow fan blade is made up of at least two sections through-flow fan blades, described through-flow fan blade one end is equipped with the rotating shaft other end axle sleeve is housed, be indent revolution shape at the end face that rotating shaft is housed, be connected by the holding screw secure fit with axle sleeve with rotating shaft between every section through-flow fan blade;
Described supporting mechanism is by bearing bracket, bearing block and bearing are formed, the drain pan of described bearing bracket and air-conditining is slidingly connected, described drain pan is provided with track, described track is laid along the bearing of trend of through-flow fan blade, the edge of this bearing bracket is provided with the slide block corresponding with this track, this bearing bracket can be slided on drain pan, there is a circular hole at the middle part of this bearing bracket, the outer ring of the inner ring socket bearing of described bearing block, the inner ring of bearing is socketed in the rotating shaft of through-flow fan blade, some ensconces the indent jatharapanvartanasana the inside of through-flow fan blade end face in the shaft length direction in the outer ring of bearing block, and another part is nested on the circular hole of bearing bracket fixing.
In described air-conditining air channel, use the multistage through-flow fan blade, connect with coaxial series system by holding screw between every section through-flow fan blade, set up supporting mechanism in the through-flow fan blade junction, through-flow fan blade is installed on the support of air-conditioner by supporting mechanism, under driven by motor, allow the multistage through-flow fan blade rotate synchronously.
According to technique scheme, under the prerequisite that does not change blower fan length, guarantee that again air quantity and noise are constant, the key that makes single through-flow fan blade into two or many through-flow fan blades is exactly that part by the bearing block of supporting mechanism places through-flow fan blade, make effective active length lengthening of through-flow fan blade, the thickness of supporting mechanism that attenuate increases makes fan outlet wide as far as possible.
Use the air-conditining of described many through-flow fan blades of use blower fan, with the air-conditining of using single through-flow fan blade blower fan under the prerequisite that air output and running noises are on close level, its through-flow fan blade length shortens greatly, has reduced secular distortion, improves the stability of household air-conditioner.The air-conditining of same specification can adopt the through-flow fan blade of different numbers, different length, and only needs this bearing bracket of translation, can realize the support to through-flow fan blade.
Description of drawings
