Abstract
The utility model relates to a hanging air conditioner with the use of a multi-cross flow blades fan, in which the single cross flow fan blades are modified into multi-section cross flow fan blades. A support mechanism of cross flow fan blades is added with the shortening of the distance of supporting points. The cross flow fan blades of each section are connected through a fastening screw with the coaxial series connection means, so that the multi-section cross flow fan blades can be in synchronous rotation. 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 the 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.
Description
Technical field
The utility model relates to fluid machinery blower fan field, relates in particular to the air-conditioner that uses many through-flow fan blades blower fan.
Background technology
In family expenses air-conditioner field, need reach the requirement of ultra-low noise and big air quantity during owing to the indoor set operation, thus all design its air outlet than broad, and the through-flow fan blade that is correspondingly adopted is also long.
Use the single air-conditioner of long through-flow fan blade, can have the high-temperature aging problem on deformation when long-play, noise from air conditioner is increased, the through-flow fan blade lost of life influences the performance of air-conditioner.Make through-flow fan blade if use other new material, then can increase cost greatly.Therefore, this problem that need solve difficult problem that always is industry.
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.
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.
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.Simultaneously flow-guiding structure is set, makes air-flow freely suitable in the fan outlet relevant position.
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.
