Abstract
An electric power tool, in particular a right-angle grinder is disclosed, having an elongated motor housing in which an electric motor is received, having a gear drive housing at a first end of the motor housing to receive a gear drive for driving a working spindle, having a handle element which is fastened rotatably at a second end of the motor housing and in which a grip switch is arranged, and having air intake slots to cool the electric motor which are arranged at the second end of the motor housing. In addition, at least one baffle plate, which serves to deflect particles and can simultaneously be configured as a cooling panel for cooling electronic components, is preferably located in the flow region of the air intake slots.
Claims6
An electric power tool comprising:
- an elongated motor housing having a first end and a second end;
- an electric motor received within said motor housing;
- a gear drive housing attached to said first end of said motor housing;
- a gear drive received within said gear drive housing and being driven by said electric motor;
- a working spindle driven by said gear drive;
- a handle element received rotatably at said second end of said motor housing;
- a grip switch arranged on said handle element for providing electric power supply to said motor;
- a plurality of air intake slots arranged on the motor housing within the proximity of the second end thereof, said air intake slots provided at two mutually opposite sides of said motor housing and allowing the entering of cooling air into the motor housing;
- and
- an insert element insertable into said motor housing, said element having a baseplate which extends substantially over a cross section of said motor housing, said baseplate carrying at least one baffle plate on each side facing toward said air intake slots provided on both opposite sides of said motor housing, wherein said baffles plates are arranged within said motor housing within a flow region of air flowing into said motor housing through said air intake slots for effecting deposition of contaminant particles within said air flowing into said motor housing.
