Climbing fan and assembly method thereof

Abstract

A floor fan and an assembling method therefor. The floor fan comprises a front mesh cover, an impeller, and a rear mesh cover (1) which are coaxially mounted. The floor fan further comprises an electric element, the electric element comprising a motor (2) used for driving the impeller. The floor fan further comprises an electric element mounting box for mounting the electric element. The electric element is mounted in the electric element mounting box by means of a first mounting structure; the electric element mounting box is an insulating box and mounted at the rear side of the rear mesh cover (1) by means of a second mounting structure (7); the first mounting structure and the second mounting structure (7) are spaced apart from each other; a first opening (6) is formed in the front surface of the electric element mounting box; a second opening is formed in the center of the rear mesh cover (1); the output shaft (14) of the motor (2) passes through the first opening (6) and the second opening in sequence and is connected to the impeller, and the output shaft (14) and the rear mesh cover (1) are spaced apart from each other. The floor fan is convenient to assemble during production without specially providing a grounding line.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a floor climbing fan and an assembly method of the floor climbing fan. Background technique [0002] Figure 1 to Figure 3 It shows a common floor climbing fan according to the prior art, which can be placed on the table or the ground through a bracket and is generally composed of front grille, rear grille, impeller, motor, bracket, switch box and other components. The surface of its metal parts is usually treated by powder spraying or electroplating. for Figure 1 to Figure 3 In the climbing fan shown, the motor is connected to the rear grille, and the motor and the rear grille are directly connected and assembled. The problems of this assembly scheme are as follows: First, because the rear grille is directly connected to the motor, it must be used Reliable grounding method, if the relevant grounding measures are not taken, once the motor leaks, the user will be in danger of...

AI Technical Summary

Problems solved by technology

for Figure 1 to Figure 3 In the climbing fan shown, the motor is connected to the rear grille, and the motor and the rear grille are directly connected and assembled. The problems of this assembly scheme are as follows: First, because the rear grille is directly connected to the motor, it must be used Reliable grounding method, if the relevant grounding measures are not taken, once the motor leaks, the user will be in danger of electric shock if he touches the rear grille and other parts conductively connected with the rear grille. Figure 1 to Figure 3 Most of the existing climbing fans shown in the above are Class I electrical appliances, the power cord needs to have a grounding wire, and there must be a corresponding grounding process. Most of the existing climbing fans use the net cover directly connected to the grounding wire, or The net cover is indirectly connected to the ground wire, and in order to achieve direct or indirect connection with the ground wire, it is necessary to scrape powder or puncture the surface treatment layer on the net cover and motor for surface treatment by powder spraying or electroplating. However, these methods are often less reliable, such as scraping powder, puncturing the surface treatment layer, or using screw connections, which are easily affected by the operation, transportation and use of the staff, that is, there is no guarantee The net cover and the ground wire are always connected. When the connection relationship between the net cover and the ground wire is broken, once the motor leaks, the user will have the risk of electric shock if he touches the rear net cover and other parts conductively connected with the rear net cover, and the grounding wire cannot be activated. protection against electric shock; secondly, see especially image 3 It can be seen that in the existing floor climbing fan, parts such as the motor 2, the capacitor 4, and the knob switch 3 are scattered on the front and rear sides of the front mesh cover and the rear mesh cover. For the floor climbing fan of this structure, In the process of assembly and disassembly, it needs to be turned over many times, the assembly and maintenance steps are cumbersome, and the production assembly efficiency and maintenance effect are low
