The above-mentioned process is a process that condensed water in the second water tank 50 reaches the first water tank 40, during which the twin tub washing dryer 1 is in the process of drying clothes, and the drain valve at the first water tank 40 controls the water outlet to be closed.

The second water box 50 continuously conveys condensed water to the first water box 40, the condensed water continuously flows into the water storage cavity, the condensed water overflows after reaching the first overflow port, the first overflow port is connected with the first overflow pipe 70, the other end of the first overflow pipe 70 is communicated with the outer barrel of the washing barrel 10, and the condensed water overflowed from the first overflow port flows to the outer barrel through the first overflow pipe 70 and then flows into the drainage channel. The above-mentioned process is a process in which the condensed water overflowed from the first water tank 40 flows out of the tub 10, during which the twin tub washing and drying machine 1 is in the process of drying clothes, and the drain valve at the first water tank 40 controls the water outlet to be closed.

The condensed water generated at the clothes drying barrel 20 is continuously accumulated in the second water box 50, the condensed water in the second water box 50 overflows after reaching the second overflow port, the second overflow port is connected with a second overflow pipe, the other end of the second overflow pipe is connected with a drainage channel, and the condensed water overflowed at the second overflow port flows to the drainage channel through the second overflow pipe, so that the condensed water is discharged out of the double-barrel washing and drying machine 1, and the washing water in the drainage channel cannot flow back into the second water box 50 due to the one-way valve. The above-mentioned process is a process in which the condensed water overflowed from the second water tank 50 flows out of the twin tub dryer 1, during which the twin tub dryer 1 is in the process of drying clothes, and the drain valve at the first water tank 40 controls the water outlet to be closed.

The second water box 50 delivers condensed water to the first water box 40, the drain valve controls the water outlet to be opened, and the condensed water enters the washing tub 10 through the water outlet after the filth is filtered out at the filter screen and falls on the laundry, thereby participating in the washing process. The above-mentioned process is a process of recycling condensed water generated in the drying process, during which the twin tub washing and drying machine 1 is switched from the drying process to the washing process.

According to the double-tub washing and drying machine 1, the first water box 40 and the second water box 50 which are communicated are arranged, the first water box 40 is communicated with the inner tub of the washing tub 10, and the second water box collects condensed water, so that the condensed water generated in the clothes drying process can be reused as washing water, and the water resource waste is effectively reduced; by arranging the water pump and the water level detector, the water level of the condensed water in the second water box 50 can be automatically detected, and the water level detector is utilized to detect the water quantity of the condensed water, so that the condensed water of the second water box 50 is controlled to be conveyed to the first water box 40; by providing the first overflow pipe 70 and the second overflow pipe, the excessive condensed water in the first water box 40 and the second water box 50 can be discharged to the drainage channel, and ineffective condensed water collection is avoided.

In some embodiments of the present invention, the first water box supporter 41 is provided between the tub 10 and the drying tub 20, and the first water box 40 is communicated with the inside of the tub 10 through a water guide pipe 43, specifically, one end of the water guide pipe 43 is connected to a water outlet at the bottom of the first water box 40, the other end of the water guide pipe 43 is connected to the inside of the tub 10, the first water box 40 is provided on the first water box supporter 41, and the water outlet is provided at the lower portion of the first water box 40.
