Drying air duct, washing and drying all-in-one machine and control method of drying air duct

Abstract

The invention provides a drying air duct, a washing and drying all-in-one machine and a control method of the drying air duct, relates to the field of washing machines, and solves the problems that clothes are accumulated at the bottom of a drum and the drying efficiency is low due to the fact that the rotating speed of an inner drum is low in the later drying period. The drying air duct comprises an air duct body, a main air inlet and flow dividing air inlets, the main air inlet and the flow dividing air inlets are formed in a door seal assembly outside a barrel and communicate with the air duct body, the main air inlet is located in the position above the middle of the door seal assembly and can enable air to be blown into the barrel, and all the flow dividing air inlets are located in the position below the middle of the door seal assembly and can enable the air to be blown into the barrel. And the wind can be blown into the cylinder. According to the drying air duct, in the later drying period, the main air inlet is turned down or closed, when the amount of clothes in the drum is larger than that of the split-flow air inlet, part of hot air sent out by the split-flow air inlet can be blown to the clothes above the split-flow air inlet, part of hot air can be blown to the clothes below the split-flow air inlet, and therefore the clothes at the bottom of the drum can exchange heat with the hot air; and the drying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a drying air duct, an integrated washing and drying machine and a method for controlling the drying air duct. Background technique [0002] The existing all-in-one washing and drying machine includes an air duct, and the dry hot air formed by the heat pump system or the heater can enter the drying air duct. The upper part of the door seal is provided with an air inlet, and the hot and dry air in the drying air duct can be sent into the cylinder through the air inlet on the upper part of the door seal, and the clothes in the cylinder are dried. [0003] When the existing all-in-one washing and drying machine dries clothes, in order to make the clothes dry evenly and increase the contact area between the clothes and the hot air, the inner cylinder rotates clockwise or counterclockwise at a certain speed and turn-to-stop ratio. However, the moisture content of the clothes ...
