Problems solved by technology

Among them, the use of two or more cross-flow fans for air supply requires a corresponding number of motors, and the material cost is relatively high; the use of specially designed blades for air supply requires changing the direction of rotation to change the direction of the air outlet, which cannot be achieved simultaneously. Two-way or multi-directional airflow, and whether the cross-flow fan is running forward or reverse, the performance of the cross-flow fan is significantly reduced. At present, there is no fan duct that uses a unidirectional rotating cross-flow fan to simultaneously achieve two-way or multi-directional airflow. design

Abstract

An air conditioner comprises a tubular fan, a heat exchanger and a driving motor for driving the tubular fan to rotate. The tubular fan has two or more than two tubular air channels, each tubular air channel is provided with an air outlet, and the two or more than two tubular air channels share the tubular fan and are axially and parallelly distributed along the tubular fan. The plurality of tubular air channels share the tubular fan, the shape of blades of the fan does not need to be specially designed, the multifunctional air outlet function can be achieved by enabling one tubular fan to rotate in the single direction, and the rotating angle of the plurality of tubular air channels can be changed according to requirements so as to achieve an optimum air feeding mode.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an air conditioner capable of blowing air in two or more directions at the same time. Background technique [0002] Cross-flow fans generally use a relatively long barrel-shaped fan impeller to work, and the blades are long, which can use a relatively low speed on the basis of ensuring the overall air circulation. The impeller in the cross-flow fan is generally a multi-blade blade type, but the two end faces are closed, and the width of the impeller is not limited. When the width increases, the flow rate also increases. Unlike the centrifugal fan, the cross-flow fan is opened on the side plate of the casing so that the airflow enters the fan axially, but the casing is partially opened so that the airflow directly enters the fan radially. Some cross-flow fans add fixed guide vanes to the inner edge of the impeller to improve the airflow state. The cross-flow fan has the character...
