the drying part 2 of the mother-and-son washing machine performs a drying operation, and the washing part 1 performs a washing operation: before starting up, the control unit 3 first detects the operating state of the drying unit 2, and if the drying unit 2 needs to perform a drying operation, the hot air supply device 201 continuously supplies high-temperature dry air to the drying drum 202 through the first pipeline L1 and the first air inlet 2021 to dry the clothes in the drying drum 202, and the high-temperature dry air joins with the clothes in the drying drum 202 to take away moisture on the clothes, so that the air becomes high-temperature and high-humidity air and is discharged through the first air outlet 2022. Meanwhile, the control part 3 determines whether the washing operation of the washing part 1 needs to be performed, if the washing part 1 needs to perform the washing operation, the control part 3 injects water into the washing tub 101 according to the selection of the user, and if the user selects to inject cold water, the control part 3 controls the fourth valve F4 to be opened, and the cold water is injected into the washing tub 101 through the cold water source 4; if the user selects to inject the warm water, the controller 3 controls the fifth valve F5 to open, and the condensing unit 204 or the warm water source 5 injects the warm water into the washing tub 101. Preferably, the control unit 3 preferentially injects warm water into the washing tub 101 using the condensing device 204, and when there is no warm water in the condensing device 204, the control unit 3 injects warm water into the washing tub 101 through the warm water source 5.

In addition, as some embodiments of the present application, the controller 3 may further open the fifth valve F5 and the fourth valve F4 at the same time, and adjust the temperature of the water injected into the washing tub 101 by controlling the opening and closing time of the fifth valve F5 and the fourth valve F4.

The controller 3 controls the first valve F1 to open the outlet on the side where the first valve F1 is connected to the washing tub 101, so that the high-temperature and high-humidity air discharged through the first exhaust port 2022 can enter the washing tub 101 from the lower part of the washing tub 101 through the second line L2, the first valve F1, and the second intake port 1011 while filling water into the washing tub 101. The high-temperature and high-humidity air moves upwards in the washing cylinder 101, heats washing water, and meanwhile drives clothes to throw up and fall down, so that the washing efficiency and the cleaning effect are improved. After passing through the washing water, the high-temperature and high-humidity air becomes low-temperature and low-humidity return air, and is discharged from the second exhaust port 1012 at the upper part of the washing drum 101 and enters the third pipeline L3, at this time, the temperature measuring device 102 on the third pipeline L3 measures the temperature of the return air in the third pipeline L3 under the control of the control unit 3, and compares the measured temperature with the temperature of the water in the condensation device 204, if the temperature of the return air measured by the temperature measuring device 102 is higher than the temperature of the water in the condensation device 204, it indicates that the water in the condensation device 204 can be heated by the return air, at this time, the control unit 3 controls the second valve F2 to open the side connected to the return air port 2041, so that the air discharged from the second exhaust port 1012 can enter the condensation device 204 through the third pipeline L3, the second valve F2 and the return air port 2041, heat exchange with the water stored in the condensing unit 204. If the temperature of the return air measured by the temperature measuring device 102 is lower than or equal to the temperature of the water in the condensing device 204, it indicates that the water in the condensing device 204 cannot be heated by the return air, and the control unit 3 controls the second valve F2 to open the side connected to the air outlet 206, so that the gas discharged from the second air outlet 1012 into the third pipeline L3 can be discharged outside the mother-daughter unit through the second valve F2, the ninth pipeline L9 and the air outlet 206.

Meanwhile, the controller 3 determines whether the washing unit 1 is performing the washing operation, and if the washing unit 1 is in the standby state, the controller 3 controls the first valve F1 to open the outlet of the first valve F1 connected to the air return opening 2041, so that the high-temperature and high-humidity air discharged from the drying drum 202 can enter the condensing unit 204 through the first exhaust opening 2022, the second pipeline L2, the first valve F1 and the air return opening 2041, exchange heat with the water stored in the condensing unit 204, and then be discharged from the air return discharge opening 2042 at the upper portion of the condensing unit 204. At this time, the control part 3 opens a side outlet that controls the second valve F2 to be connected to the air outlet 206, so that the air discharged from the return air discharge port 2042 can be discharged to the outside of the mother-son unit through the second valve F2, the ninth pipe L9 and the air outlet 206.

If the temperature of the water in the condensing unit 204 is lower than the preset temperature, the controller 3 opens the fifth valve F5 to communicate with the sixth pipeline L6, so that the water in the warm water source 5 can be injected into the washing tub 101. During the washing process, when the washing drum 101 discharges water through the water discharge port 1013, the control unit 3 identifies the washing process, and if the washing process is a washing stage, the control unit 3 controls the side of the third valve F3 connected to the drain pump 103 to be opened, so that the water in the washing drum 101 can be discharged to the outside of the main and sub-machines through the water discharge port 1013, the eighth pipeline L8, the third valve F3, the drain pump 103 and the water outlet 104.

Meanwhile, the control unit 3 detects the water level in the condenser 204 by the water level detecting device 205, and when the water level in the condenser 204 is lower than a predetermined water level, the control unit 3 controls the open/close states of the third valve F3 and the second valve F2 to replenish the water amount in the condenser 204. When the water level in the condensing unit 204 is equal to or higher than the preset water level, the control part 3 opens the side of the third valve F3 connected to the drain pump 103, so that the water in the washing tub 101 can be directly discharged to the outside of the sub-unit through the drain port 1013, the eighth line L8, the third valve F3, the drain pump 103 and the water outlet 104.
