US 10,881,257 B2 · Cleaner and method for controlling cleaner

Abstract

The present disclosure includes a main body, a cleaning tool assembly connected to the main body to be movable in at least one axial direction, a handle part connected to the main body and configured to receive an applied force of a user, a detection part provided in the handle part and configured to detect a magnitude and a direction of the force applied to the handle part, and a control part configured to control the movement direction of the cleaning tool assembly based on the detected direction of the force and to control the movement distance of the cleaning tool assembly based on the detected magnitude of the force. In this way, the steering performance may be improved by reducing a horizontal load felt by a user when the user holds and moves the handle of the cleaner, fatigue felt when performing the cleaning operation may be removed by removing a vertical load applied by the handle, and convenience may be improved.

A cleaner comprising:

a main body;
a brush assembly including a housing connected to the main body and a set of wheels configured to be movable in at least one direction;
a handle part connected to the main body and configured to receive an applied force of a user, wherein the handle part includes:
a body part;
a cap part disposed to be spaced apart from the body part;
a guide part disposed between the body part and the cap part;
and
a sliding part slidably installed at the guide part and configured to straightly move and rotationally move relative to the guide part between the body part and the cap part;
a detection part provided in the handle part and configured to detect a magnitude and a direction of the applied force to the sliding part;
and
a control part configured to decide a rotational speed and a rotation amount of a plurality of wheels in the set of wheels using at least one of the direction and the magnitude of the applied force.

A cleaner comprising:

a main body;
a brush assembly including a housing connected to the main body and a set of wheels configured to be movable with respect to a surface to be cleaned;
a handle part connected to the main body, configured to be graspable, and configured to relatively move with respect to the main body, wherein the handle part includes:
a control part configured to be graspable;
and
a guide part configured to guide forward-to-back and side-to-side movements of the control part relative to the guide part;
and
a driving module configured to control a movement speed of the set of wheels and a rotation amount of the set of wheels relative to the main body such that the movement speed and the rotation amount are controlled to vary according to a relative movement amount of the handle part,
wherein the guide part includes:
a rotation guide part configured to relatively rotate with respect to the main body;
and
a movement guide part formed by being bent and extending from the rotation guide part and configured such that the control part is movable with respect to the main body.
