Description

technical field [0001] The invention relates to an electric fan which is used as an electric fan in summer and as a heater in winter. Background technique [0002] Electric fans are electrical appliances that are only used in summer, and are kept in storage rooms outside of summer. On the other hand, a heater is an electrical product used only in winter, and is stored in a storage room outside of winter. For these electrical products, it takes a lot of time to store and take them out as the seasons change, and it is necessary to ensure a large storage space. As a solution to this problem, International Publication No. WO00 / 58669 discloses an electric fan that can also be used as an electric fan or a heater as needed. The method of changing the electric fan which also serves as a heater from the state which can be used as an electric fan to the state which can be used as a heater is as follows. First, remove all the rotor blades, the protective net covering the front of th...
