Problems solved by technology

With a high-power electric motor, an inefficient electric motor, or stress peaks during cleaning operation, in particular, fans inherent in the motor are not sufficient to pass away the waste heat, under the installation conditions that are usually quite restricted in space.
It is a disadvantage i

Embodiment Construction

[0026]Referring now in detail to the drawings, FIG. 1 shows an electric vacuum head 1 according to the invention, in a perspective view. The electric vacuum head 1 has a housing 2, in which an electric motor 4 for driving a cleaning device 5 configured as a brush roller is disposed in a motor chamber 3. The bristles of the brush roller pass through a vacuum mouth 7 that runs on the underside of housing 2, over the width of the electric vacuum head 1, and is delimited by a front vacuum mouth edge 6a and a rear vacuum mouth edge 6b. Sealing lips 8a, 8b are disposed in front of front vacuum mouth edge 6a and behind rear vacuum mouth edge 6b, in the movement direction. In addition to display elements 9, 9′, and operating elements 10, air entry openings 11 of motor chamber 3, for passage of air to cool electric motor 4, can be seen at the top of the housing 2. Electric vacuum head 1 has a vacuum connector 12 for a connection to a suction tube 13 or a vacuum cleaner housing, configured as...

Abstract

An electric vacuum head for a vacuum cleaner has a housing, a cleaning device that can be driven by an electric motor disposed within the housing in a motor chamber, a vacuum mouth on the underside of the housing delimited by vacuum mouth edges, and a vacuum connector. The motor chamber has at least one air entry opening for entry of air to cool the electric motor, and at least one air exit opening. The air exit opening is disposed on the underside of the housing so that the cooling air that exits from the air exit opening during operation of the electric vacuum head enters into the vacuum mouth by way of at least one of the vacuum mouth edges.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]Applicants claim priority under 35 U.S.C. 119 of European Application No. 07 022 070.2 filed Nov. 14, 2007.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to an electric vacuum head for a vacuum cleaner, having a housing, a cleaning device that can be driven by an electric motor disposed within the housing in a motor chamber, a vacuum mouth on the underside of the housing delimited by vacuum mouth edges, and a vacuum connector. The motor chamber has at least one air entry opening for entry of ambient air, and at least one air exit opening.[0004]The electric vacuum head can have a rechargeable battery or also an electrical connector to the voltage supply, by way of a vacuum cleaner. Without restriction, the electric vacuum head can be connected by way of a suction tube and a flexible hose, or directly to a vacuum cleaner housing. If the vacuum head is connected directly to the vacuum cleaner housing, t...
