EXAMPLE III

As shown in fig. 9 to 12, the present embodiment is further described in detail based on the first and second embodiments:

the drying device comprises a drying module 46, and an air outlet duct 40 and an air return duct 41 which are respectively communicated with the drying module 46, wherein the air outlet duct 40 and the air return duct 41 are respectively communicated with a treatment chamber for containing objects to be dried, and the dried air of the drying module 46 enters the treatment chamber through the air outlet duct 40, is dried and heats the objects to be dried, and then is discharged out of the treatment chamber through the air return duct 41; the flow rate of the drying air in the air outlet duct 40 per unit time is greater than that of the drying air in the air return duct 41 per unit time.

Carry the stoving wind through drying module in to the treatment chamber, the realization is dried the thing of treating in to the treatment chamber, it is greater than the stoving wind circulation in the 41 unit times in return air wind channel to make the 40 unit times in air-out wind channel stoving wind circulation through structural design, the amount of wind that makes the stoving wind in the treatment chamber is sufficient, on the other hand, the dwell time of stoving wind in the treatment chamber is long, the moisture on the enough furthest's of stoving wind clothing is taken away, improve the utilization ratio of stoving wind, realize better stoving effect.

The air outlet duct 40 and the air return duct 41 both have the smallest cross-sectional parts in the direction perpendicular to the drying air direction, and the cross-sectional area of the smallest cross-sectional part on the air outlet duct 40 is larger than that of the smallest cross-sectional part on the air return duct 41.

The sectional area of the minimum part of the upper section of the air outlet duct 40 is larger than that of the minimum part of the upper section of the air return duct 41, so that the drying air flow in unit time of the air outlet duct 40 is larger than that of the air return duct 41, the drying air in the treatment chamber is in full contact with the to-be-dried objects, the mass transfer and the heat transfer are realized, and the drying efficiency of the drying device on clothes is improved.

The section ratio of the minimum part of the upper section of the air outlet duct 40 to the minimum part of the upper section of the return air duct 41 is 1.5-1.9:1. the air output of air-out wind channel 40 is different with the return air volume in return air wind channel, and the stoving effect of the clothing of treating drying is different, and the air output of air-out wind channel 40 is big, can improve the drying efficiency and the stoving effect of treating the stoving article, but if the air output volume and the return air volume are mismatched, too big if the air output, cause the serious waste of electric resource easily, if the air output undersize, can reduce drying efficiency, user experience is poor. When the ratio of the section of the minimum part of the upper section of the air outlet duct 40 to the section of the minimum part of the upper section of the air return duct 41 is 1.5-1.9, the balance of resources and drying efficiency is realized, the articles to be dried are dried to the maximum extent under the condition of less resource output, moreover, the section of the air outlet duct 40 is large, the drying air cannot be directly discharged without mass transfer and heat transfer, the drying air is more easily dispersed in the treatment chamber, the contact area with the articles to be dried is large, the drying efficiency of the clothes to be dried is improved, and the clothes are more fluffy.

Further, the ratio of the section of the minimum section of the air outlet duct 40 to the section of the minimum section of the return air duct 41 is 1.7:1.

in the first scheme, the air outlet duct 40 and the air return duct 41 are both ducts with unchanged cross sections, and the cross section of the air outlet duct 40 is larger than that of the air return duct 41. Because the section of the air outlet duct 40 is larger than that of the air return duct, the air outlet quantity is larger than the air return quantity, the drying wind energy in the treatment chamber is high, and the drying effect is good.

In the second scheme, the air outlet duct 40 and/or the return air duct 41 are partially retracted into the duct to form a retracted portion, the section of the retracted portion is the smallest, and the section of the retracted portion of the air outlet duct 40 is larger than that of the retracted portion of the return air duct 41.

For example, the air outlet duct 40 and the air return duct 41 have the same cross section, but a retracted part is arranged in the air return duct 41 to reduce the inner diameter of the part, so that the air outlet volume in unit time is larger than the air return volume, and the drying effect and the drying efficiency of the washing machine are improved.

In addition, both the air outlet duct 40 and the return air duct 41 may be provided with a retracted portion, so that the cross section of the retracted portion of the air outlet duct 40 is larger than that of the return air duct 41.

Furthermore, the communication port between the air outlet duct 40 and the processing chamber is an air outlet 42, the air outlet 42 is the position with the smallest cross section on the air outlet duct 40, the communication port between the return air duct 41 and the processing chamber is a return air port 43, the return air port 43 is the position with the smallest cross section on the return air duct 41, and the cross section of the air outlet 42 is larger than the cross section of the return air port 43. Because the air outlet 42 and the air return port 43 are connected with the treatment chamber, the section of the air outlet 42 is larger than that of the air return port, drying air enters the treatment chamber after being discharged from the air outlet 42, and because the air outlet 42 is larger, the flow rate of the drying air in the air outlet duct 40 in unit time is larger than that of the drying air in the air return duct 41 in unit time, so that the inlet air of the drying air in the treatment chamber is larger than that of the exhaust air, the drying air is fully contacted with an object to be washed, and a better drying effect is realized; on the other hand, the air outlet 42 of the drying device is large, so that the air is convenient to disperse when entering the treatment chamber again, the contact surface with the articles to be dried is large, and the drying effect is improved.

Further, the section ratio of the air outlet 42 to the air return opening 43 is 1.5-1.9:1, realize resource consumption and drying efficiency's balance, furthest's stoving treats the stoving article under less resource output, and in addition, drying device's air outlet cross-section is big, and the stoving wind is changeed the dispersion in the treatment chamber, and is big with the area of contact of treating the stoving article, improves the drying efficiency of treating the stoving clothing, and the clothing is fluffier moreover.

The cross section ratio of the air outlet 42 to the air return opening 43 is preferably 1.7, at this time, the consumption of electric energy and the like and the utilization efficiency of heat reach a certain balance, and under the condition of the minimum consumption output of electric energy and the like, the best and fastest drying of the articles to be dried is realized.
