Preferably, as shown in fig. 3, the injection structure 7 is an injection structure, wherein the air inlet 701 is communicated with the air pipe 1, the drainage port 702 is communicated with the air pipe 703, and the other end of the air pipe 703 is communicated with the ambient air; hot humid air enters the injection structure 7 through the vent pipe 1 and the air inlet 701, and low-temperature and low-humidity ambient air in the air pipe 703 is sucked into the injection structure through flowing negative pressure.
Furthermore, an adjusting valve 704, such as but not limited to a solenoid valve, an electronic expansion valve, etc., may be connected between the air pipe 703 and the drainage port 702 of the injection structure 7, and whether ambient air enters the injection structure 7 or not and the amount of air entering the injection structure 7 may be controlled by controlling the opening degree of the adjusting valve 704. When the ambient air temperature and humidity are high, the amount of air entering can be reduced, the regulating valve 704 can be closed under the limit condition to prevent the ambient air from entering, and the negative effect of the high-humidity high-temperature ambient air suction on the drying process is avoided. Meanwhile, under the limit condition, the regulating valve 704 is closed, and the pressure loss in the injection structure 7 can be increased, so that the ventilation volume entering the vent pipe 1 is reduced, the condensation rate of hot humid air is reduced, and condensation inside and outside the water box 2 is relieved.

The temperature T and the relative humidity phi after mixing can be calculated by the formula, the mixed air forms low-temperature dry air after being cooled and decelerated to enter the water box 2, and when the temperature of the wall surface of the water box 2 is higher than the temperature of the mixed air in the water box, condensation can not be generated in the water box 2.
When stable moist hot air flows into the ventilation pipe 1, the temperature T in the ventilation pipe 12Air quantity G2Relative humidity phi2At a fixed value, the state parameter of the gas mixture is determined by the air quantity G of the introduced ambient air0And (6) determining. Thus, the amount G of the introduced ambient air is adjusted by controlling the adjusting valve 7040So as to ensure that no condensation is generated in the drying chamber.
Preferably, as shown in fig. 2, a metal plate 5 is arranged between the water box 2 and the handle 3 of the integrated washer dryer. The metal plate can cause condensation of hot humid air flowing therethrough on the surface thereof. Because the cavity of the water box 2 is respectively communicated with the vent pipe 1 and the water inlet flexible joint pipe 4, the condensation generated on the metal plate 5 can be guided into the water inlet flexible joint pipe 4 to form a water sealing effect.

1) starting a drying program of the washing and drying integrated machine;
2) separately detecting rings by sensorsAmbient humidity phi0And humidity phi in the breather pipe 11；
3) If the relationship of the detected humidity values is: phi is less than or equal to 90%1≤Φ0When the humidity is less than or equal to 100%, namely the ambient air is also in a high humidity state, the air pipe 703 is closed through the regulating valve 704, and the ambient air is stopped from entering the injection structure;
