The present invention relates to an artificial intelligence washing machine and an operation method thereof. A method of operating a washing machine may comprise estimating, based on a previous setting of a previous washing operation, an estimated setting for a current washing operation, wherein the estimated setting includes a water supply time, a drainage time, and a spin-drying time, obtaining a user input, obtaining an amount of laundry from a weight sensor of the washing machine, determining, based on the estimated setting, the user input, and the amount of laundry, a washing time for the current washing operation and displaying the determined washing time to the user. Accordingly, the estimated washing time is provided with the reflection of data of the washing machine which has been accumulated by the increase of the number of uses, thereby reducing a difference between an actual operating time and the estimated washing time and minimizing the user inconvenience.

The invention relates to a program-controlled apparatus (1) for washing items that is equipped with a water purification system (8) for purifying the wash liquor by removing detergent and suspended soil, which purification system (8) utilizes addition of flocculant, wherein the amount of flocculant that is added is controlled to minimize the total amount of flocculant used without compromising the efficacy of the purification treatment.

A laundry treating apparatus includes a tub configured to hold wash water, a drum rotatably supported in the tub and including a shaft disposed perpendicular with the ground, and a sub-drum detachably mounted to the drum and configured to wash laundry independently from the drum. The sub-drum includes a discharging area in which a discharging path is defined to selectively discharge the wash water in the sub-drum by a centrifugal force generated by rotation of the sub-drum. A check valve is included in the discharging area and is configured to selectively open and close the discharging area when acted on by an external force applied by the centrifugal force generated by the rotation of the sub-drum.

The present disclosure relates to an intelligent positive and negative pressure system and an operation method therefor, and an intelligent positive and negative pressure electric appliance. The system comprises a positive and negative pressure intelligent fresh-keeping refrigerator, a positive and negative pressure intelligent washing machine, a positive and negative pressure dish washing and fruit and vegetable cleaning machine, a positive and negative pressure range hood, a positive and negative pressure baking and frying microwave oven, a positive and negative pressure fresh-keeping compartment container, a positive and negative pressure fresh-keeping warehouse, a positive and negative pressure disinfection machine, and a positive and negative pressure module cabinet. By means of the positive and negative pressure system, a fluid and a carried substance thereof are regulated and controlled by means of positive and negative pressure, so as to affect an object in a specific space in a targeted manner.

Automated laundry systems are provided for laundering laundry articles in bulk. A user places their laundry articles into a receptacle, initiates a laundry cycle, and the receptacle is thereafter transported to at least one laundry device for the laundry articles to be washed and dried, and then transported to be prepared for retrieval, which may include sorting or folding the laundry articles. After initiating the laundry cycle, the user's presence is no longer required. A notification is sent to an user's device that their laundry articles are ready to be retrieved. Once the user indicates that they are ready to retrieve their laundry articles, such as via an app on their mobile device, the laundry articles may be transported to an area accessible by the user.
