WASHING MACHINE
Document Type and Number:
Japanese Patent JP2022160166
Kind Code:
A
Abstract:
To provide a washing machine capable of detecting fixing of a washing treatment agent with an inexpensive and simple structure, in an automatic input tank.SOLUTION: A washing machine includes: an automatic input device including a treatment agent tank capable of storing a washing treatment agent for a plurality of times, and drive means driven for inputting the washing treatment agent in the treatment agent tank into a water tub; detection means for detecting a residual amount of the washing treatment agent in the treatment agent tank; and control means for controlling a washing operation. The detection means has at least two preset liquid level detection points. The control means integrates an input amount of the washing treatment agent according to the drive of the drive means and acquires it as an estimation amount, and also compares, with the estimation amount, a difference between a first residual amount and a second residual amount detected from the two liquid level detection points as an actual input amount. Thereby, fixing of the washing treatment agent in the treatment agent tank is detected.SELECTED DRAWING: Figure 6
