Description

Drying structure for cleaning machine and cleaning machine

Technical Field

The utility model relates to the technical field of cleaning machines, in particular to a drying structure for a cleaning machine and the cleaning machine.

Background

The dish washer is a household appliance for automatically washing tableware, and is gradually accepted by consumers, and after the existing dish washer washes dishes, the inner wall of the liner and the tableware have more residual water, and the drying is generally realized through the residual heat of the liner and the tableware. However, as the residual water in the inner container is more and the inner container is cooled faster, the residual heat of the inner container is insufficient to evaporate the residual water, so that the inner container still has more water in a long time after the bowl is washed, and the peculiar smell in the dish washing machine is heavier under the condition that the door body of the dish washing machine is tightly closed for a long time.

Aiming at the problems, chinese patent No. CN201820319612.0 (bulletin No. CN 208958049U) discloses a drying system of a dish washer, which comprises an inner container and a respirator, wherein the respirator is arranged outside the inner container and is provided with an exhaust channel which is communicated with the inside and the outside of the inner container, and the drying system further comprises a hot air generating device, wherein the hot air generating device is provided with a hot air output end, and the hot air output end is communicated with the inside of the inner container. The drying system of the dish washer can be used for drying the inside of the inner container by additionally arranging the hot air generating device, so that the drying condition of the inside of the dish washer after the tableware of the dish washer is washed can be obviously improved, the tableware is kept dry, bacterial breeding is reduced, and peculiar smell is inhibited.

However, if the hot air generating device is used for conveying hot air which is not dried into the inner container, after the drying is finished and the moist hot air is not blown, the inner container is moist, and the places with high humidity can be condensed into water drops after the temperature is reduced, so that the drying effect is poor.

Aiming at the problems, the Chinese patent application with the patent number of CN201510242750.4 (with the publication number of CN 106264408A) discloses a semiconductor condensation drying device, a dish washer and a condensation drying method, wherein the cold end of a semiconductor condenser is arranged at the air inlet of an air duct and is used for dehumidifying the air inlet of a fan; the hot end of the semiconductor condenser is arranged in the air duct and is used for heating the circulating air.

Thus, although the semiconductor condenser can dehumidify air and then enter the inner container to dry tableware, namely, dry hot air is conveyed into the inner container, the patent also needs to arrange a water collecting tank at the bottom of the air duct to collect condensed water condensed by the semiconductor condenser, which is more troublesome.
