Problems solved by technology

At the beginning of the drying process, the temperature of the air is relatively low. Since the existing air duct is a fixed structure, all the air in the drying circulation air path still needs to be cooled by the evaporator first, and then condensed. The heater is heated, causing the temperature of the air to increase slowly, which affects the drying efficiency

Abstract

The invention provides an air passage, a heat pump clothes drying device and a heat pump clothes drying control method. The air passage comprises a reducing pipe and an evaporator-mounting pipe; the evaporator-mounting pipe has at least two air passages which are mutually independent; the reducing pipe is communicated with at least one air passage. According to the scheme, the evaporator-mounting pipe has the at least two air passages which are mutually independent; at the beginning of clothes drying, air is allowed to flow through an evaporator from one air passage only, and the evaporator has low refrigerating action on the air; correspondingly, when the air is heated by a condenser, the temperature rises fast, and heating the air to the normal temperature takes a shorter time; therefore, drying efficiency is improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of heat pump drying clothes, in particular to an air duct, a heat pump drying device and a heat pump drying control method. Background technique [0002] The current heat pump dryer includes a clothes dryer barrel and an air duct connected with the dryer barrel to form a drying circulation air path, and an evaporator and an evaporator are sequentially arranged in the air duct along the air flow direction of the drying circulation air path. condenser. In the process of drying clothes, firstly, the air is sucked from the dryer cylinder into the evaporator, and the evaporator condenses and precipitates the water vapor in the air, and the air after the water vapor is separated enters the condenser for heating, and then enters the dryer after heating Drum, cycle in turn until the end of drying. At the beginning of the drying process, the temperature of the air is relatively low. Since the existing air duct is a...
