The detergent mixer includes additive cartridges that accommodate liquid additives, additive pumps corresponding to the additive cartridges, and a flow channel box including pump intake paths that guide the additives from the additive cartridges to the additive pumps and pump discharge paths that guide the additives discharged from the additive pumps. The discharge guiding mechanism guides the additives discharged from the pump discharge paths to the water supply guide flow channel.

The present disclosure relates to a method of controlling a garment folding machine, which may effectively prevent damage to a drive motor and a loss of power caused by an overload of the drive motor by accurately detecting and determining a situation in which garments are lumped during a process of conveying or folding the garments, may effectively prevent damage to the lumped garments and related components, and may significantly reduce the time for which the operation of the folding machine is stopped by accurately specifying the position at which the garments are lumped and then notifying a user of the position to allow the user to take an immediate action.

Method of controlling garment folding machine

A washing machine includes a tub containing water, a drum disposed rotatably in the tub, the drum receiving laundry and a detergent supply device supplying detergent to the tub, wherein the detergent supply device comprises a plurality of cartridges respectively containing detergent, a pump sucking detergent contained in the plurality of cartridges and a passage switching valve selectively allowing the pump to be fluidly communicated with one of the plurality of cartridges.

The present disclosure relates to a garment folding machine and a method of controlling the garment folding machine, in which it is possible to effectively prevent damage to a garment by controlling and reducing tension after detecting and determining a situation in which the tension is applied to the garment during a process of conveying or folding the garment, and it is possible to allow the folding machine to smoothly perform vertical folding by disposing the garment at an appropriate position in order to perform the vertical folding.

Garment folding machine and method of controlling same

According to the present disclosure, a washing machine includes: a cabinet; a tub disposed in the cabinet and configured to receive water; a drum rotatably disposed in the tub and configured to receive laundry; a drawer configured to be inserted into and withdrawn out of the cabinet, the drawer being configured to contain detergent; a first passage connecting the drawer and the tub; a detergent supply device disposed at the cabinet, the detergent supply device being configured to contain detergent; and a second passage disposed between the detergent supply device and the tub or between the detergent supply device and the drawer, the second passage being configured to guide the detergent contained in the detergent supply device to the tub or the drawer.

The present disclosure relates to a washing machine and a control method of the same. The washing machine includes a tub, a drum, and a detergent supply device configured to supply an additive to the tub. The detergent supply device includes a plurality of cartridges configured to contain the additive, a plurality of check valve assemblies that are respectively connected to the plurality of cartridges and configured to control extracting of the additive from the plurality of cartridges, a pump, a water supply valve configured to receive water from an external water source, and an outlet pipe having a plurality of check valve connection pipes that are respectively connected to the plurality of check valve assemblies, the outlet pipe passing therethrough the water supplied from the water supply valve and the additive extracted from the plurality of cartridges.

Method and apparatus for washing machine

The present disclosure relates to a washing machine including a tub, a drum, and a detergent supply device configured to supply an additive to the tub. The detergent supply device includes a plurality of cartridges storing additive, a plurality of check valve assemblies connected to the plurality of cartridges and configured to control extracting of the additive, a pump for extracting additive, an inlet channel defining a plurality of flow paths respectively connected to the plurality of check valve assemblies, where the inlet channel is configured to transmit a pressure change generated by the pump to the plurality of check valve assemblies, and a flow path switching valve connected to the pump and the inlet channel and configured to selectively establish fluid communication between the pump and any one of the plurality of flow paths of the inlet channel.
