Embodiment Construction

[0035] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0036] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to an axial air supply device, a fan, an air conditioner and an air supply control method. The axial air supply device comprises a first axial fan blade, a second axial fan blade, a first driving mechanism and a second driving mechanism, wherein the second axial fan blade is rotatably arranged in the first axial fan blade; the first driving mechanism is connected with the first axial fan blade and is used for driving the first axial fan blade to do a rotary motion relative to the second axial fan blade; and the second driving mechanism is connected with the second axial fan blade and is used for driving the second axial fan blade to do a rotary motion relative to the first axial fan blade. The positive and negative air supply of the axial air supply device can be independently controlled; additionally, according to the axial air supply device, the second axial fan blade is arranged in the first axial fan blade, and the second axial fan blade does not occupy the external space, so that the size of the whole axial air supply device is small.

Description

technical field [0001] The invention relates to the technical field of air conditioning equipment, in particular to an axial flow air supply device and a fan, air conditioner and air supply control method with the axial flow air supply device. Background technique [0002] The axial flow air supply device is named because the gas flows parallel to the fan shaft. Axial flow air supply devices are widely used in daily life, so higher requirements are put forward for the performance of axial flow air supply devices. [0003] For example, it is required in many occasions that the axial flow air supply device can realize two-way air supply, and in order to achieve two-way air supply, the traditional axial flow air supply device usually adopts a special airfoil or a combination of blades, and controls the positive and negative rotation of the motor. To achieve two-way air supply. [0004] The traditional axial flow air supply device, when the forward air supply is required, the ...
