Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] Such as Figure 1 to Figure 3 The shown cross-flow fan blades include at least two stages of middle-section fan blades 1 coaxially connected, and all the middle-section fan blades 1 have a first state of being arranged side by side and a second state of fully overlapping or partially overlapping, that is, When the cross-flow fan blades are working normally, all the middle-section fan blades 1 are in the first state, thereby ensuring the maximum air output of the cross-flow fan blades, and when the cross-flow fan blades are in a stopped state, all the middle-section fan blades 1 are in the fi...

Abstract

The invention provides cross-flow fan blades and an air conditioning unit. The cross-flow fan blades comprise at least two stages of middle-section fan blades which are coaxially connected, all the middle-section fan blades are provided with first states and second states, wherein the first states are arranged side-by-side and the second states are overlapped or partially overlapped. According tothe cross-flow fan blades and the air conditioning unit, the middle-section fan blades are arranged to be of an overlapping structure, the size of the cross-flow fan blades can be reduced as much as possible, so that the installation is facilitated; and in a working state, all the middle-section fan blades can be restored to the side-by-side arrangement state under the action of rotation, the optimal working state is guaranteed, so that the problem that the cross-flow fan blades are not convenient to install due to too large size is effectively solved.

Description

technical field [0001] The invention relates to the technical field of fan equipment, in particular to a cross-flow fan blade and an air conditioning unit. Background technique [0002] With the rapid development of science and technology, the demand for central air conditioners in the market is increasing. Many types of fan blades are currently used in the central air conditioners sold on the market. As a fan blade with a large air output, the cross-flow fan blade is used in many models. However, the traditional cross-flow fan blade has a relatively long length. Long, it will be very difficult to install. Contents of the invention [0003] In order to solve the technical problem of difficult installation of cross-flow fan blades, a cross-flow fan blade and an air-conditioning unit with reduced installation volume are provided under the condition of ensuring normal working conditions. [0004] A cross-flow fan blade, comprising at least two stages of middle-section fan b...
