The action principle is that the whole drying system is a circulating system, a heater in the drying system is used for heating dry air, the dry air enters a cylinder body to take away wet load on clothes and is changed into slightly high-temperature wet air, then the slightly high-temperature wet air enters a drying system condenser to reversely flow with lower cold water to carry out heat and moisture exchange, the temperature of the slightly high-temperature wet air is reduced, part of moisture content flows away along with the cold water, the humidity is reduced to be slightly dry low-temperature air, and the slightly dry low-temperature air enters the heater again to be heated.

Example 2
s301: and judging whether water exists at the water outlet of the condenser or not, and draining water by using the condensed water second drainage port when water exists at the water outlet of the condenser.
By adopting the step S301, in the drying process, the low-temperature water obtained after the heat exchange of the high-temperature water flowing out of the condenser occurs in the heat exchange unit enters the water inlet of the condenser through the second condensed water outlet, so that the condensed water can be recycled. Meanwhile, in order to reduce the energy of the heat exchange unit as much as possible, the inlet of the heat exchanger in the heat exchange unit is required to be normal temperature water, and the outlet water temperature of the second drain pipe is controlled by adjusting the water flow of the heat exchange inlet pipe and the condensate water second drain pipe, so that the temperature difference between the temperature and the initial inlet pipe temperature of the condenser is minimum.
As a further scheme, before step S301, the method further includes: the temperature Ta in the cylinder (namely the temperature of the air flow in the cylinder) is detected, and when the temperature of the Ta reaches the temperature T of the cylinder which is set by a system and stops heating, cold water is pumped into a condenser by a water pump. Under the drive of the fan, hot air in the cylinder enters the condenser to perform heat-moisture exchange with low-temperature condensed water, and the heat-moisture exchange can be realized only by ensuring a certain temperature difference requirement. Therefore, the moisture content of the heat and the moisture can be cooled and dehumidified by the cold water only after the temperature in the cylinder reaches a certain value.
S302: acquiring the remaining drying time and the drain time of the condensed water in the washing machine.
As a specific embodiment, the drain time of the condensed water in the washing machine is obtained by the following method: acquiring the volume of condensed water in the washing machine; acquiring the set flow of the second condensate water outlet; and calculating the drainage time of the condensed water in the washing machine according to the volume of the condensed water in the washing machine and the set flow of the second condensed water outlet. The method has high accuracy of the calculated discharge time, and is convenient for more accurate logic control of the program.
S303: and when the residual drying time is equal to the drainage time of the condensed water in the washing machine, closing the second drainage port of the condensed water, and draining water by using the first drainage port of the condensed water.
By adopting the step S303, the low-temperature water obtained after the heat exchange of the high-temperature water flowing out of the condenser in the heat exchange unit is performed can be injected into the washing machine through the first condensed water drainage port at the final drying stage, and the condensed water is converted into the washing water, so that the condensed water is utilized by 100%, and the waste caused by directly draining the condensed water at the final drying stage is avoided.
In the embodiment of the invention, the water discharged through the first drain outlet of the condensed water can be directly injected into the washing machine to participate in washing, and can also be stored in the first drain heat-preservation box.
To achieve accurate control when converting condensed water into washing water. The following two schemes are employed. The first scheme is suitable for the condition that the use environment temperature of the washing machine is higher than a first preset temperature, and the second scheme is suitable for the condition that the use environment temperature of the washing machine is lower than or equal to the first preset temperature. Wherein, the first preset temperature can be set according to the freezing temperature of the water.
Specifically, as shown in fig. 4, the first scheme includes the following steps:
(11) and judging whether the first condensed water drainage port has water or not.
(12) And when the first condensed water drainage port has water, the washing machine is filled with water through the first condensed water drainage port.
For example, the washing machine may be filled with water through the condensed water first drain port in the following manner: acquiring a first temperature of water at a first drain outlet of the condensed water; when the first temperature is higher than a second preset temperature, the washing machine is filled with water through the condensed water first drainage port and a third water inlet of the washing machine; and acquiring the current water injection amount in the washing machine, and stopping water injection when the current water injection amount is equal to the preset water injection amount. When the first temperature is lower than or equal to the second preset temperature, water is injected into the washing machine through the condensed water first drain port; when the washing machine is filled with water through the condensed water first drain port, the current water filling amount of the washing machine is obtained; stopping water injection when the current water injection amount is equal to the preset water injection amount; and when the current water injection amount is still less than the preset water injection amount after the washing machine is completely injected with water through the first condensed water discharge port, continuing to inject water into the washing machine through a third water inlet of the washing machine until the current water injection amount is equal to the preset water injection amount. Further, after continuing to fill water into the washing machine through the third water inlet of the washing machine until the current water filling amount is equal to the preset water filling amount, the method further includes: heating water in the washing machine; stopping heating when the water in the washing machine reaches the second preset temperature. Thereby providing a laundry effect.
In order to realize accurate control of the water injection temperature of the washing machine, the flow rates of the water in the first condensed water drainage port and the third condensed water inlet port can be adjusted according to the first temperature and the temperature of the outside water.
(13) And when the first condensed water drainage port has no water, judging whether the heat exchange water outlet has water.
(14) And when water is available at the heat exchange water outlet, water is injected into the washing machine through the heat exchange water outlet.
For example, the washing machine may be filled with water through the heat exchange water outlet in the following manner: acquiring a first temperature of water at the heat exchange water outlet; when the first temperature is higher than a second preset temperature, injecting water into the washing machine through the heat exchange water outlet and a third water inlet of the washing machine; and acquiring the current water injection amount in the washing machine, and stopping water injection when the current water injection amount is equal to the preset water injection amount. When the first temperature is lower than or equal to the second preset temperature, injecting water into the washing machine through the heat exchange water outlet; when the washing machine is filled with water through the heat exchange water outlet, the current water filling amount of the washing machine is obtained; stopping water injection when the current water injection amount is equal to the preset water injection amount; and when the current water injection amount is still less than the preset water injection amount after the washing machine is completely injected with water through the heat exchange water outlet, continuing to inject water into the washing machine through a third water inlet of the washing machine until the current water injection amount is equal to the preset water injection amount.
