Abstract

The purpose of this invention is to provide an electric fan improving assembly workability of an ion discharging part and preventing a control substrate from getting wet when liquid intrudes in a base part from a hole mistakenly formed on the base part. In the electric fan provided with an ion discharging part, an installation part on which the ion discharging part is installed is formed integrally with the base part, and a prevention body preventing the ion discharging part from coming out of the installation part is formed on a bottom cover. A guide part guiding liquid such as water intruding into the base part from the hole formed on the base part to a lower part without passing through a control part is provided.

Description

technical field [0001] The present invention relates to an electric fan provided with an ion releasing unit. Background technique [0002] In such an electric fan, as a method of attaching the ion releasing part to the base part, there are two holding members sandwiching the ion releasing part from the side to hold the ion releasing part, and fitting the holding part with the base part above the control board. The method of fixing with screws after joining. (Japanese Patent Document No. 2003-093767, page 4, FIG. 4 ). [0003] However, in this method of attaching the ion releasing unit, in order to fix the ion releasing unit, in addition to a plurality of holding members, an assembly process of fixing the holding members with screws is required. [0004] Also, if liquid such as water is spilled on the base by mistake, the liquid enters the base through the hole formed on the base and wets the control substrate, which may short-circuit the control substrate and damage the co...
