Abstract
A device for protecting a motor in a vacuum cleaner is provided. The device includes a lower casing for forming a lower portion of a main body of the cleaner, a motor housing, which is installed in the lower casing and includes the driving motor therein and an upper portion of which is opened upwardly, a filtering device installed onto the lower casing for filtering out foreign materials from introduced air, and an intermediate cover integrally formed with a first cover portion positioned onto an upper portion of the filtering device and a second cover portion for covering the upper portion of the motor housing. Further, a pressure switch for sensing pressure within the motor housing and a damper for introducing external air into the motor housing when the pressure within the motor housing is lowered below a predetermined pressure value are directly installed onto the second cover portion of the intermediate cover.

10. A device for protecting a driving motor in a vacuum cleaner, comprising:
-
a lower casing configured to form a lower portion of a main body of a vacuum cleaner; an upper casing configured to form an upper portion of the main body of the vacuum cleaner; a motor housing installed in a front portion of the lower casing and configured to receive therein a driving motor; an inlet formed in a front portion of the upper casing and configured to receive therethrough suction air into the vacuum cleaner; and a filtering device installed in a rear portion of the lower casing and configured to create a downwardly swirling flow of suction air, wherein suction air is received into an upper portion of the filtering device and flows downward, the suction air being discharged out of the vacuum cleaner through an outlet, and wherein the filtering device comprises a filter configured to filter foreign materials contained in the suction air, a portion falling from the suction air due to gravity and another portion being removed from the suction air by the filter. - View Dependent Claims (11, 12, 13)
