Abstract

A hand-held machine tool ( 1 ) is provided including a housing ( 2 ), with a drive device for actuating a tool that can be brought into operative connection with the machine tool ( 1 ) and a control device ( 8 ) for actuating the drive device ( 4 ) being provided, and the control device ( 4 ) being designed with a control element ( 10 ), and at least one capacitive sensor element ( 32, 33 ) operatively connected to the control device ( 10 ) being provided. The at least one sensor element ( 32, 33 ) and/or the control element ( 10 ) is at least partially, in particular almost completely separated from a main channel ( 50 ) of the machine tool ( 1 ) in which the drive device ( 4 ) is arranged.

Claims (27)

1 . A hand-held machine tool comprising:

a housing;

a drive for actuating a tool bringable into operative connection with the machine tool;

a controller for actuating the drive, the controller being designed with a control element; and at least one capacitive sensor operatively connected to the controller, the at least one sensor or the control element being at least partially separated from a main channel of the machine tool, the drive being arranged in the main channel;

wherein the at least one sensor is at least partially designed as a line.

2 . The hand-held machine tool as recited in claim 1 wherein the at least one sensor or the control element is arranged in a region completely separated from the main channel.

3 . The hand-held machine tool as recited in claim 1 wherein the at least one sensor element is arranged in a channel.

4 . The hand-held machine tool as recited in claim 1 wherein the at least one sensor includes a plurality of sensors, each sensor being at least partially arranged in a separate channel separated from the main channel.

5 . The hand-held machine tool as recited in claim 1 wherein the at least one sensor includes two sensor elements at least partially arranged together in one channel.

6 . The hand-held machine tool as recited in claim 1 wherein the control element is arranged in a chamber.

7 . The hand-held machine tool as recited in claim 6 wherein the at least one sensor element is arranged in a channel and wherein the chamber is separated from the channel.

8 . The hand-held machine tool as recited in claim 7 wherein the housing includes at least two parts, with the channel or the chamber being jointly formed by the at least two parts.

9 . The hand-held machine tool as recited in claim 1 wherein the control element has a control unit and a signal generator.

10 . The hand-held machine tool as recited in claim 1 further comprising a power switch operatively connected to the controller, the controller being designed to transfer the power switch between an inactive state and an active state, with a user actuation of the power switch in the active state of the power switch leading to an actuation of the drive.

11 . The hand-held machine tool as recited in claim 1 wherein the line extends from the control element to a detection region of the sensor.

12 . A hand-held machine tool comprising:

a housing;

a drive for actuating a tool bringable into operative connection with the machine tool;

a controller for actuating the drive, the controller being designed with a control element; and

at least one capacitive sensor operatively connected to the controller, the at least one sensor or the control element being at least partially separated from a main channel of the machine tool, the drive being arranged in the main channel;

wherein the at least one sensor includes two sensor elements at least partially arranged together in one channel.

13 . A hand-held machine tool comprising:

a housing;

a drive for actuating a tool bringable into operative connection with the machine tool;

a controller for actuating the drive, the controller being designed with a control element; and

at least one capacitive sensor operatively connected to the controller, the at least one sensor or the control element being at least partially separated from a main channel of the machine tool, the drive being arranged in the main channel;

wherein the housing includes at least two parts, with the channel or the chamber being jointly formed by the at least two parts.
