Problems solved by technology

[0004] The problem solved by the present invention is that when the existing air conditioner is being cleaned, water tends to flow into the bearing fixing seat along the end face of the cross-flow fan blade, corroding the bearing rubber ring, and generating a lot of noise when the air conditioner is running, which affects the user experience

Embodiment 2

[0055] The second embodiment provides a bearing fixing seat 11, such as Figure 11-13 As shown, the bearing fixing seat 11 includes a cylindrical shell 15, the cylindrical shell 15 is a hollow structure, and an opening 16 is provided at the end of the cylindrical shell 15 connected to the cross-flow vane 1, A bearing rubber ring is provided inside the cylindrical housing 15 .

[0056] The bearing fixing seat 11 has two opposite ends, and a water baffle 18 is provided on one end thereof, specifically at the end where the cylindrical shell 15 of the bearing fixing seat 11 is connected to the cross-flow vane 1 A water baffle 18 is arranged, and the water baffle 18 is an annular water baffle that surrounds the cylindrical housing 15 in one circle. The water baffle 18 extends from the side wall of the cylindrical housing 15 to the axial direction of the cylindrical housing 15 to form an inwardly bent edge. The outer side of the annular water baffle is connected to the cylindrical...

Embodiment 3

[0063] The third embodiment provides a bearing fixing seat 11, such as Figure 14-16 As shown, the bearing fixing seat 11 includes a cylindrical shell 15, the cylindrical shell 15 is a hollow structure, and an opening 16 is provided at one end of the cylindrical shell 15 connected to the cross-flow fan 1 , a bearing rubber ring is provided inside the cylindrical housing 15 .

[0064] The bearing fixing seat 11 has two opposite ends (the cylindrical housing 15 has two opposite ends), and one of the ends is provided with a water-repellent groove 19, that is, the bearing fixing seat 11 and the cross-flow vane A water-repellent groove 19 is provided on the outer wall of the one end connected to 1 (that is, the outer wall of the one end of the cylindrical casing 15). By setting the drain groove 19 on the outer circle of the end connecting the bearing fixing seat 11 and the cross-flow fan 1, when water flows to the outer circle of the bearing fixing seat 11, the water can flow down...

Abstract

The invention provides a cross-flow fan blade, a bearing fixing seat, a fan assembly and an air conditioner. The bearing fixing seat is provided with two end parts, wherein a water draining groove isformed in one end part. According to the cross-flow fan blade, the bearing fixing seat, the fan assembly and the air conditioner, water is prevented from entering the bearing fixing seat to corrode arubber bearing ring; a large number of noise which influences the user experience is avoided while the air conditioner runs.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cross-flow fan blade, a bearing fixing seat, a fan assembly and an air conditioner. Background technique [0002] With the continuous development of science and technology, more and more home appliances have entered people's daily life and work. Household appliances take an air conditioner as an example. The air conditioner can provide a cooling or heating effect through heat exchange in a cold or hot environment, so as to provide a comfortable indoor environment. [0003] However, the right end surface of the cross-flow fan blade of the existing air conditioner (i.e. the end face of the end connected to the cross-flow fan blade and the bearing holder) is usually a plane structure, and the cross-flow fan blade and the bearing holder lack a suitable waterproof structure. When the cross-flow fan blade of the air conditioner is used, water will flow into the bearing fixi...
