The most core parts are the motor, fan blades, and a volute. The function of the fan blade volute is to guide the airflow sucked in by the fan blades to the fan outlet and increase the wind speed. In order to ensure the flow guidance and acceleration effect of the fan blade volute, there are clear requirements for the gap between the fan blade volute and the fan blade, so there are high requirements for operating accuracy during the production and assembly process. If the staff does not assemble it in place or the assembly position deviation is large, there will be problems such as excessive noise during the operation of the indoor unit, shaking of the whole machine, abnormal air outlet, etc., which is not conducive to subsequent use. Therefore, the equipment process requires the staff to be very careful and careful, resulting in a lot of time to complete the assembly, which is not conducive to the guarantee of production efficiency.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1~Figure 2As shown, its structural relationship is as follows: it includes a fan blade 4 and a volute, and also includes a fan mounting plate 1, a bracket 2, a fan blade positioning structure 3 and a volute fixing hole 6; the fan mounting plate 1 is provided with an air outlet and a volute fixing hole 6, the bracket 2 is installed on the fan mounting plate 1, a motor is installed inside the bracket 2, the fan blade 4 is installed at the output end of the motor, the fan blade positioning structure 3 is located at the air outlet, and limits the position of the fan blade 4 relative to the air outlet, and the volute is fixedly installed on the fan mounting plate 1 through the volute fixing hole 6;

[0021] The fan blade positioning structure 3 includes a handle 31 , a left foot 32 and a right foot 33 . The left foot 32 and the right foot 33 are in a tapered step structure, and the left foot 32 and the right foot 33 are fixedly connected to the handle 31 .

[0022] Preferably, the fan blade positioning structure 3 can be an integrated structure or a split structure.

[0023] Preferably, the fan blade 4 is also provided with a clearance hole 5 .

[0024] The clearance hole can facilitate the staff to insert the tool into the fan blade 4 to fix the fan blade 4 on the output end of the motor, thereby improving the convenience of installation.

[0025] Preferably, the number of air outlets is not less than one.

[0026] When used specifically, the following processes are included:

[0027] In the first step, the staff installs the motor inside the bracket 2. Then, the staff installs the bracket 2 on the fan mounting plate 1 through bolts. At this time, the bolts cannot press against the bracket 2, so that the bracket 2 can still move in a small range.

[0028] In the second step, the staff installs the fan blade 4 on the output end of the motor. Then, the staff takes out the fan blade positioning structure 3 and places it at a suitable position of the air outlet. This position allows the left clamping foot 32 and the right clamping foot 33 to clamp the air outlet and fix the fan blade 4 at the same time. Finally, the staff tightens the bolts on the bracket 2 to limit the movement of the bracket 2 relative to the fan mounting plate 1.

[0029] In the third step, the staff turns the fan blade 4 to a suitable position, which allows the clearance hole 5 and the connecting bolts between the motor output end and the fan blade 4 to be in the same straight line. Then, the staff inserts the tool into the clearance hole 5 and tightens the connecting bolts between the motor output end and the fan blade 4 to limit the movement of the fan blade 4 relative to the motor output end.

[0030] In the fourth step, the staff installs the volute onto the fan mounting plate 1 through the volute fixing hole 6 to complete the installation.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
