Abstract

The present invention discloses a fan with cooling and heating dual purpose, and comprises a base seat, a front protective cover, a heating device, fan blades, a rear protective cover, and a motor. On the base of the existing single cooling fan, the present invention exchanges the rear protective cover into a reflecting and ventilation protection dual-purpose cover; the rear protective cover is connected with a motor through bolts, and the heating device is arranged in the hollow cavity between the front protective cover and the fan blades. Besides the functions of owned by the single cooling fan, the present invention also has the function of heating in winter. The present invention enables one object to have more functions, and the installation is convenient. The price is lower, and the present invention is warmly welcomed among the middle and the low income groups. The application field and the market prospect are very broad.

Description

technical field [0001] The invention relates to a fan for household electrical appliances, in particular to a fan with both cooling and heating functions. Background technique [0002] Currently known common single cooling fans (desk fans, floor fans) on the market are generally used only in summer when cooling is required, making people feel cool, and are generally idle in winter and do not have winter heating effects. Even if there are other 2-in-1 cooling and heating fans, their prices are relatively high, which is difficult for ordinary users to accept. In order to improve these deficiencies, a single cooling electric fan that is mostly idle in winter is organically combined with a special electric heating device (infrared heating device and reflector, etc.), and a reasonable transformation is made to make a dual-purpose cooling and heating fan at a low cost. It came into being. Contents of the invention [0003] The object of the present invention is to provide a co...
