Description

Clothes treating apparatus Technical Field The present disclosure relates to a laundry treatment apparatus. Background International application WO2019/049697 discloses a washing machine (laundry treatment apparatus) with a centrifugal separation portion 94. As shown in fig. 1, the main operation principle of the washing machine is that laundry is put into a washing tank 92 in a washing stage, after the washing machine is operated until the washing water reaches a predetermined water level, a circulation pump 93 is operated, the washing water is fed into a centrifugal separator 94 from a separator inflow port 941 through a first switching valve 95, a circulation pump 93, and a second switching valve 96, after the centrifugal separator 94 centrifugally separates foreign matters contained in the washing water, the washing water is fed back into an outer tank 91 from a separator outflow port 942 through a third switching valve 97, and the circulation operation is repeated until the washing water is discharged in a draining stage, and in the draining stage, the circulation pump 93 is operated, the washing water is fed into the centrifugal separator 94 from the separator outflow port 942 through a first switching valve 95, a circulation pump 93, a second switching valve 96, and a third switching valve 97 to flush the centrifugal separator 94, and the washing water after the centrifugal separator 94 is flushed is discharged out of the washing machine through a first opening and a second opening and closing valve 98 and a second opening and 99. However, in the above-described washing machine (laundry machine), the water path is complicated in design, and a circulation pump, a plurality of switching valves, and an on-off valve are required to be provided, which increases the manufacturing cost, and also complicates the control flow during operation, which is prone to failure. Disclosure of Invention Problems to be solved by the invention The present disclosure has been made in view of the above-described circumstances, and an object thereof is to provide a laundry treatment apparatus capable of simplifying a waterway design. Solution for solving the problem In order to achieve the above object, a first aspect of the present disclosure provides a laundry treatment apparatus including an outer tub provided in a housing of the laundry treatment apparatus, a washing tub rotatably provided in the outer tub, a centrifugal separation part for separating foreign matters contained in washing water in the outer tub, and a water dividing structure including a housing having an inner cavity, the housing being provided with a water inlet, a circulating water outlet, and a washing water outlet, which are respectively communicated with the inner cavity, the laundry treatment apparatus including a circulating waterway in which the washing water in the outer tub flows from the water inlet into the water dividing structure and flows from the circulating water outlet into the centrifugal separation part, and returns to the outer tub after centrifugal separation of the foreign matters contained in the washing water by the centrifugal separation part, and a washing water in the outer tub flows from the water inlet into the water dividing structure and flows from the washing water outlet into the centrifugal separation part to wash the centrifugal separation part, and returns to the water dividing structure. According to the first technical scheme, by arranging the water diversion structure and enabling the circulating water channel and the flushing water channel to share the water diversion structure, the water channel design can be simplified, and the switching valve and the opening and closing valve can be reduced or omitted, thereby being beneficial to reducing the manufacturing cost and simplifying the control flow in the operation process. In addition, by dividing the circulation water channel and the flushing water channel at the water dividing structure, the circulation water channel and the flushing water channel can be designed differently as required, and for example, different foreign matter filtering requirements can be satisfied by adding different filtering parts to the circulation water channel and the flushing water channel. A second aspect is the laundry machine according to the first aspect, wherein the casing is provided with a drain port communicating with the inner chamber, the laundry machine includes a drain water path in which the washing water in the outer tub flows into the water dividing structure from the water inlet, and is discharged from the drain port to the outside of the laundry machine. According to the second technical scheme, the water diversion structure is shared by the circulating water channel, the flushing water channel and the draining water channel, so that the water channel design can be further simplified. The third technical means is the clothes treating apparatus of the first technical me
