Abstract
In order to accomplish a solution task of the present disclosure, a cleaner hand according to an embodiment of the present disclosure may include a pipe configured to transfer at least one of air, dust, and foreign matter to a drive unit that generates a suction force, a grip portion connected to the pipe, and formed to be gripped by a user, a sensor unit disposed in the grip portion to sense information related to whether or not the grip portion is gripped by the user, and a controller configured to control the drive unit based on the sensed information.
Claims10
A cleaner handle, comprising:
- a pipe configured to transfer at least one of air, dust, and foreign matter to a drive unit that generates a suction force;
- a grip portion connected to the pipe, and formed to be gripped by a user;
- a sensor unit disposed in the grip portion to sense information related to whether or not the grip portion is gripped by the user;
- and
- a controller configured to control the drive unit based on the sensed information,
- wherein the sensor unit comprises:
- a temperature sensor configured to sense a temperature of a part of an outer surface of the grip portion, and
- a pressure sensor configured to sense a pressure applied to a part of the outer surface of the grip portion, and
- the controller operates the drive unit when the sensed temperature is above a reference temperature value and the sensed pressure is above a reference pressure value, controls the pressure sensor to sense a pressure applied to a part of the outer surface of the grip portion at regular cycles when the sensed temperature is above a reference temperature value, compares a pressure sensed in a current cycle with a pressure sensed in a previous cycle, and controls the drive unit based on the comparison result.

A cleaner, comprising:
- a cleaner body;
- a drive unit disposed in the cleaner body to generate a suction force;
- a pipe configured to transfer at least one of air, dust and foreign matter to the drive unit;
- a dust collector disposed in the cleaner body to filter dust in air transferred from the pipe;
- a grip portion connected to the pipe, and formed to be gripped by a user;
- a sensor unit disposed in the grip portion to sense information related to whether or not the grip portion is gripped by the user;
- and
- a controller configured to control the drive unit based on the sensed information,
- wherein the sensor unit comprises:
- a temperature sensor configured to sense a temperature of a part of an outer surface of the grip portion, and
- a pressure sensor configured to sense a pressure applied to a part of the outer surface of the grip portion, and
- the controller operates the drive unit when the sensed temperature is above a reference temperature value and the sensed pressure is above a reference pressure value, controls the pressure sensor to sense a pressure applied to a part of the outer surface of the grip portion at regular cycles when the sensed temperature is above a reference temperature value, compares a pressure sensed in a current cycle with a pressure sensed in a previous cycle, and controls the drive unit based on the comparison result.
