In some embodiments of the present invention, in some embodiments,

The drying equipment is a roller washing and drying machine.

The inner cylinder air outlet 15 is arranged at the bottom of the inner cylinder, hot and humid air flowing out after heat exchange with clothes is used for beating the bottom wall of the rear cylinder, then the hot and humid air contacts with the first condensation cavity (the guide rib 13 and the bottom wall of the rear cylinder) for heat exchange condensation, and then the hot and humid air rises along the bottom wall of the rear cylinder and is subjected to heat exchange with the second condensation cavity (the blocking device 3) for re-condensation. The wet and hot air after the twice condensation is converted into air flow with relatively low temperature and humidity, and the air flow enters the drying air duct 7 for heating under the action of the centrifugal fan, so that the next heat exchange is circularly implemented.

1. The bipolar condensing cavity provided by the utility model optimizes the defects of rear air duct condensation and rear barrel condensation on the basis of the prior art. The second condensing part and the first condensing part formed by the rear cylinder condensing plate and the rear cylinder condensing ribs are used as a condensing cavity of the whole machine to replace a rear air duct for condensation, and the hot and humid air passes through the first condensing cavity before entering the second condensing part arranged at the position of the air outlet. The twice condensation part ensures the full heat exchange of the hot and humid air. The larger wind resistance generated by the rear air duct cavity is avoided, the smoother heat exchange is realized, and the air quantity generated by the centrifugal fan can be circulated to the greatest extent.

2. In the embodiment of the utility model, the metal plate with a larger heat exchange coefficient is preferably adopted as the second condensing part of the drying air duct component, and when the heat exchange of the hot and humid air passing through the first condensing part is insufficient, the hot and humid air passes through the second condensing part with a better heat exchange effect again, so that the sufficient heat exchange between the hot and humid air and the air duct condensing cavity is ensured. The component parts of the air duct component are also more simplified, and the cost of the whole machine is ensured while the drying efficiency is higher.

3. The profiling part is arranged on the baffle plate to ensure that the baffle plate is fully distributed with the largest area of condensed water to realize the largest area of condensation, thereby better realizing the heat exchange between the hot air at the air outlet position and the baffle plate. The baffle plate provided by the utility model not only serves as a second condensing part for heat exchange with hot and humid air, but also serves as a baffle plate at the position of a condensed water inlet to ensure the stability of the condensed water inlet position. The condensed water passing through the baffle stably flows into a second condensing part (smooth transition of the tail end of the baffle) formed by the guide ribs. And the splash can not be generated due to unstable water inflow under the condition of unstable water pressure. Therefore, the splash defect of the guide rib in the prior art caused by unstable water pressure is overcome.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model. The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that modifications and variations can be made without departing from the technical principles of the present utility model, and these modifications and variations should also be regarded as the scope of the utility model.
