Abstract
A washing machine includes: a housing; a tub inside the housing; a case connected with the tub; a filter attachable to or detachable from the case; a filtering flow path formed to pass through a portion of the filter; a bypass flow path formed to bypass the portion of the filter; and at least one sensor configured to obtain information about a state of the filter. The washing machine includes; a flow path switching device configured to guide water entered into the case to the filtering flow path or the bypass flow path; and a controller configured to control the flow path switching device to guide the water based on the obtained information about the state of the filter.
Claims19
A washing machine comprising:
- a housing;
- a tub inside the housing;
- a case connected with the tub;
- a filter attachable to or detachable from the case;
- a filtering flow path formed to pass through a portion of the filter;
- a bypass flow path formed to bypass the portion of the filter;
- at least one sensor configured to obtain information about a state of the filter;
- a flow path switching device configured to guide water entered into the case to the filtering flow path or the bypass flow path, the flow path switching device comprising:
- a bypass body installed at an outer circumference of the case and configured to form the bypass flow path;
- a bypass door rotatably installed inside the bypass body and configured to open or close the bypass flow path;
- and
- a bypass driver installed on the bypass body and configured to operate the bypass door;
- and
- a controller configured to control the flow path switching device to guide the water based on the obtained information about the state of the filter.
A washing machine comprising:
- a tub;
- a case connected with the tub;
- a filter attachable to or detachable from the case;
- at least one sensor configured to detect clogging of the filter;
- a flow path switching device configured to guide water entered into the case to pass through the filter or bypass the filter, the flow path switching device comprising:
- a bypass body installed at an outer circumference of the case and configured to form a bypass flow path;
- a bypass door rotatably installed inside the bypass body and configured to open or close the bypass flow path;
- and
- a bypass driver installed on the bypass body and configured to operate the bypass door;
- and
- a controller configured to control the flow path switching device based on the clogging of the filter detected by the at least one sensor.
A method for controlling a washing machine, the washing machine including a tub, a case connected with the tub, a filter attachable to or detachable from the case, at least one sensor, a flow path switching device, and a controller the method comprising:
- detecting of clogging of the filter using the at least one sensor;
- and
- controlling the flow path switching device, by the controller, to guide water entered into the case to pass through the filter or bypass the filter based on the detecting of clogging of the filter,
- wherein the flow path switching device includes:
- a bypass body installed at an outer circumference of the case and forming a bypass flow path;
- a bypass door rotatably installed inside the bypass body;
- and
- a bypass driver installed on the bypass body, and configured to operate the bypass door to open or close the bypass flow path.
