Problems solved by technology
When the air conditioner is stored in the warehouse, the cross-flow fan blade will be subjected to gravity perpendicular to its axial direction. When the storage time is long, under the action of gravity, the whole cross-flow fan blade will be deformed by falling, especially the middle part of the cross-flow fan blade , the situation of falling deformation is particularly serious, and may even lead to the breakage of cross-flow fan blades
[0004] The deformed cross-flow fan will not work normally, and its unbalanced rotation will cause the overall air conditioner to vibrate, which not only seriously affects the quality of the air conditioner, but also produces a lot of noise, and the user experience is extremely poor

Embodiment Construction
[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0034] The air conditioner is a commonly used household equipment. The inside of the air conditioner is generally equipped with cross-flow fan blades. The two ends of the cross-flow fan blades are respectively fixed by fixed shafts. In some air conditioners, the cross-flow fan blades are bent and deformed, and the deformed cross-flow fan blades will not operate normally, and their unbalanced rotation will cause the overall air conditioner to vibrate, seriously affecting the quality of the air conditioner, and generating large noise. Reduced user experience.
[0035] The inventor thought about the above problems and found that the air conditioners have passed strict quality inspections when they leave the factory, so the cross-flow fan blades of the ...

The invention provides a cross-flow fan blade, and at least part of the cross-flow fan blade is prepared through first magnetic materials. The invention provides a cross-flow fan blade protection assembly used for protecting the provided cross-flow fan blade, the cross-flow fan blade protection assembly comprises a protection device covering the cross-flow fan blade, at least part of the protection device is prepared through second magnetic materials, magnetic force is formed between the cross-flow fan blade and the protection device, and the magnetic force at least partially offsets the gravity of the cross-flow fan blade. The invention provides an air conditioner, and the air conditioner comprises the provided cross-flow fan blade. The invention provides an air conditioner protection assembly used for protecting the provided air conditioner. In the cross-flow fan blade, the cross-flow fan blade protection assembly, the air conditioner and the air conditioner protection assembly, themagnetic force is formed between the cross-flow fan blade and the protection device, the magnetic force at least partially offsets the gravity, the cross-flow fan blade is not prone to deformation inthe long-term storage process, and the quality of the cross-flow fan blade is guaranteed.
Description
technical field [0001] The invention relates to the field of air conditioners, in particular to a cross-flow fan blade, a cross-flow fan blade protection component, an air conditioner and an air conditioner protection component. Background technique [0002] With the gradual improvement of people's living standards and the rapid development of the household appliance industry, people's demand for air conditioners is gradually increasing. Improving the quality of air conditioners to improve user experience is one of the main goals of various manufacturers. [0003] In the prior art, the air conditioners are equipped with cross-flow fan blades, which are located inside the air conditioner, and the two ends of the cross-flow fan blades are respectively fixed by fixed shafts. The cross-flow fan blades can be applied to external units or indoor cabinets. After the air conditioner is produced and assembled, it is often stored in the warehouse first, and then transported to the mal...
