Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air cooling apparatus for a vacuum cleaner using a thermoelectric element, and more particularly, to a cooling apparatus for air inside a vacuum cleaner using internal air heated by heat of an electric motor and a thermoelectric element for cooling the motor.

In order to solve such a problem, the present invention provides an electric blower which exposes a heat absorbing portion to internal air introduced into the electric blower, exposes the exothermic portion to air discharged to the outside through the electric blower, And a device.

By adopting such a configuration, the inside air of the vacuum cleaner and the heat of the motor, which are heated by the heat of the electric motor, are cooled, thereby improving the degree of vacuum during cleaning and increasing the suction efficiency.
