Description

Climbing fan and assembly method thereof

Technical field

The present invention relates to the field of household electrical appliances, and in particular to a climbing fan and a method of assembling the climbing fan.

Background technique

1 to 3 show a common climbing fan according to the prior art, that is, can be placed on a table or a ground by a bracket, generally consisting of a front grille, a rear grille, an impeller, a motor, a bracket, and a switch box. The surface of the metal parts is usually treated by dusting or electroplating. For the climbing fan shown in Figures 1 to 3, the motor is connected to the rear grille, and the direct connection assembly between the motor and the rear grille is performed. The assembly scheme has the following problems: First, due to the rear grille and the motor Direct connection, therefore, a reliable grounding method must be used. If the relevant grounding measures are not taken, if the motor leaks, the user will be exposed to the rear grille and other parts that are electrically connected to the rear grille, which will cause electric shock. Therefore, as shown in Figure 1, The existing climbing fan machine shown in Figure 3 is mostly Class I electrical appliances. The power cable needs to have a grounding wire, and there must be a corresponding grounding process. The existing climbing fans are mostly used to directly connect the mesh cover to the grounding wire. Connection, or the use of a mesh cover indirectly connected to the grounding wire, and in order to achieve direct or indirect connection with the grounding wire, it must be damaged by scraping, puncture, etc. on the mesh cover and motor using surface treatment by dusting or plating. The process of surface treatment layer, or by screw connection, however, these methods are often less reliable, such as scraping powder, puncture surface treatment layer or screw connection, etc. The effect of operation, transportation and use, that is, the mesh cover and the connecting wire are not always connected. When the connection relationship between the mesh cover and the connecting wire is broken, if the motor leaks, the user contacts the rear mesh cover and is electrically connected with the rear mesh cover. The other part will have the risk of electric shock, and the grounding wire can't protect against electric shock. Secondly, especially as shown in Figure 3, in the existing climbing fan, parts such as motor 2, capacitor 4, and knob switch 3 are scattered. The ground cover is distributed on the front and rear sides of the front net cover and the rear net cover. For the climbing fan of this structure, in the assembly and disassembly process, it needs to be repeatedly turned over, the assembly and maintenance steps are cumbersome, the production assembly efficiency and the maintenance effect are both Lower.
