Abstract
A dishwasher performs a method for providing a notification for replacing a filter. The dishwasher continues to accumulate operation time of an air blowing fan of the dishwasher, and when total accumulative operation time is predetermined time or greater, outputs a notification for replacing a filter through a display or a speaker to determine the timing of the replacement of the filter accurately.
Claims18
A dishwasher comprising:
- a tub that defines a wash space therein;
- a door configured to open and close the wash space;
- a dry air supply part comprising an air blowing fan and a filter;
- a non-transitory memory;
- and
- a processor configured to control operation of the dishwasher,
- wherein the processor is configured to:
- accumulate, in the non-transitory memory, (i) an operation time for which the air blowing fan operates and (ii) a number of times of a drying process based on operation of the air blowing fan,
- perform (i) a comparison of a total accumulative operation time of the air blowing fan accumulated in the non-transitory memory based on the operation of the air blowing fan with a predetermined first time and (ii) a comparison of the number of times of the drying process with a number of predetermined times,
- output at least one of an optical signal or an acoustic signal to notify a user to replace the filter based on at least one of (i) the total accumulative operation time being greater than or equal to the predetermined first time or (ii) the number of times of the drying process being greater than or equal to the predetermined times, and
- based on the filter being replaced, initialize the total accumulative operation time and the number of times of the drying process, and stop outputting the at least one of the optical signal or the acoustic signal.

A dishwasher, comprising:
- a dry air supply part comprising an air blowing fan and a filter;
- a communication device;
- a non-transitory memory;
- and
- a processor configured to control operation of the dishwasher,
- wherein the processor is configured to:
- accumulate, in the non-transitory memory, (i) an operation time for which the air blowing fan operates and (ii) a number of times of a drying process based on operation of the air blowing fan,
- perform (i) a comparison of a total accumulative operation time of the air blowing fan accumulated in the non-transitory memory based on the operation of the air blowing fan to a with a predetermined first time and (ii) a comparison of the number of times of the drying process with a number of predetermined times,
- output at least one of an optical signal or an acoustic signal to notify a user to replace the filter based on at least one of (i) the total accumulative operation time being greater than or equal to the predetermined first time or (ii) the number of times of the drying process being greater than or equal to the predetermined times, and
- based on the filter being replaced, initialize the total accumulative operation time and the number of times of the drying process, and stop outputting the at least one of the optical signal or the acoustic signal.

A method for providing a notification for replacing a filter of a dishwasher, the method comprising:
- accumulating (i) an operation time for which an air blowing fan operates and (ii) a number of times of a drying process based on operation of the air blowing fan;
- performing (i) a comparison of a total accumulative operation time of the air blowing fan accumulated based on the operation of the air blowing fan with a predetermined first time and (ii) a comparison of the number of times of the drying process with a number of predetermined times;
- outputting at least one of an optical signal or an acoustic signal to notify a user to replace the filter based on at least one of (i) the total accumulative operation time being greater than or equal to the predetermined first time or (ii) the number of times of the drying process being greater than or equal to the predetermined time;
- and
- based on the filter being replaced, initializing the total accumulative operation time and the number of times of the drying process, and stopping output of the at least one of the optical signal or the acoustic signal.
