Floor fan and assembling method thereof

Abstract

The invention relates to the field of household appliances and discloses a floor fan and an assembling method thereof. The floor fan comprises a front net cover, an impeller and a rear net cover, wherein the front net cover, the impeller and the rear net cover are mounted coaxially. The floor fan further comprises an electric element. The electric element comprises a motor used for driving the impeller. The floor fan further comprises an electric element mounting box used for mounting the electric element. The electric element is mounted in the electric element mounting box through a first mounting structure. The electric element mounting box is an insulating box and is mounted on the rear side of the rear net cover through a second mounting structure. The first mounting structure is spaced from the second mounting structure. A first opening is formed in the front surface of the electric element mounting box, a second opening is formed in the center of the rear net cover, an output shaft of the motor sequentially penetrates through the first opening and the second opening so as to be connected to the impeller, and the output shaft is spaced from the rear net cover. According to the floor fan, no grounding wire needs to be arranged specially, and the floor fan can be assembled conveniently when manufactured.

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
