Abstract

The present disclosure relates to a cleaner with improved safety with respect to a cleaning module. According to an embodiment of the present disclosure, changes in postures of the cleaning module may be measured through one or more sensors included in a motion detecting part. Therefore, there is an advantageous effect that a problem for the user to have injuries by a mop containing high temperature steam does not occur. In addition, according to the present disclosure, a planar motion displacement of the cleaning module may be measured through one or more sensors included in the motion detecting part. Accordingly, when a control unit detects that the cleaning module is left in a state of contacting a surface to be cleaned for a long period of time, the drive of a feedwater pump, a heater, and a mop motor is controlled to stop. Therefore, there is an advantageous effect that the flooring of the surface to be cleaned is not damaged.

Dependent claims

A cleaner configured to wet clean a surface to be cleaned using a rotating mop, comprising:

a main body in which an operating part configured to receive an instruction and a main battery configured to supply electric power are disposed;
and
a cleaning module to which the main body is connected on an upper part thereof and to which the mop is connected on a lower part thereof,
wherein the cleaning module comprises:
a water container;
a heater configured to generate steam to be supplied to the mop from water stored in the water container;
a feedwater pump configured to press the water stored in the water container to be pressure-fed into the heater;
a mop motor connected to the mop and configured to be driven to rotate the mop;
a motion detecting part configured to detect a motion of the cleaning module;
a load measuring part configured to measure a rotational load of the mop;
and
a control unit configured to control the cleaning module in a safety mode when the motion detecting part detects that the cleaning module is in a tilted state compared to a surface to be cleaned, or when the load measuring part detects a certain magnitude reduction with respect to the rotational load, and
wherein the safety mode control is a stopping operation of at least one among the heater, the feedwater pump, and the mop motor.
