[0064] Preferably, in combination with the above scheme, as Figures 1-7 As shown, the present application further provides a laundry treatment equipment, which condenses the air, exchanges heat and dehumidifies when starting to run the drying program and entering the drying judgment stage after the temperature rising is completed; the condensation structure provided by the present application is designed with two condensation modes:

[0065] When the laundry treatment equipment runs the drying program and enters the drying judgment stage, the air in the laundry treatment cylinder 1 enters the rear air duct 3 through the laundry treatment cylinder first air outlet 13 and the first air inlet 21, and enters the rear air duct 3 through the laundry treatment cylinder second air outlet 14 and the second air inlet 22, and exchanges heat with the first pipe section of the heat exchange pipeline located in the air cavity, so as to realize condensation; specifically, the first pipe section takes away the heat of the air in the air cavity, and the water in the air adheres to the first pipe section; after the first pipe section starts to condense, the temperature of the copper pipe of the first pipe section will rise, but the heat of the copper pipe will be absorbed by the heat exchange medium inside to reduce the temperature, and the heat exchange medium that absorbs heat will flow through the radiator to be branched to each small area by the heat dissipation fins, and then be accelerated by the second fan on the radiator to dissipate heat, and the heat dissipated air passes through the heat exchange air duct 5 and the rear air duct 3 by the action of the second fan, and the air is sent to the electric heating component to be heated to become dry air and then enters the laundry treatment cylinder.

[0066] Preferably, in combination with the above scheme, as Figures 1-7 As shown, in the embodiment, the first pipe section heat exchange medium is circulated to the second pipe section of the heat exchange pipeline by the second pump 7, exchanges heat with the heat exchanger 9, and the air after heat exchange with the heat exchanger 9 enters the rear air duct 3 through the heat exchange air duct 5, and is dehumidified by the heating component in the rear air duct 3.

[0067] When the clothes treatment equipment runs the drying program and enters the drying judgment dry stage, the condensed water is opened, the condensed water enters the air cavity from the rear air duct water inlet 23, and can flush the first pipe section of the heat exchange pipe in the air cavity and exchange with the hot and humid air, take away the moisture of the air and reduce the temperature; Specifically, the air in the clothes treatment cylinder 1 enters the rear air duct 3 through the clothes treatment cylinder first air outlet 13, the first air inlet 21, and the clothes treatment cylinder second air outlet 14, the second air inlet 22, and exchanges heat with the condensed water in the air cavity, realizing condensation.

[0068] In the above scheme, the clothes treatment equipment adopts an electric heating condensation mode, which can produce local temperature and accumulate heat, and the heat conversion efficiency is low; the condensation structure provided by the present application, when the air blown by the radiator is added, will become hot air by electric heating and enter the clothes treatment cylinder to dry the clothes, and the hot and humid air will be taken out and cooled again, so the design makes the heat conversion efficiency of electric heating high, and heat accumulation will not occur, which can also save power consumption; At the same time, when the heat exchange pipe condenses, there will be condensation on the copper pipe of the heat exchange pipe, and the condensation on the copper pipe will make the lint adhere to it, which can temporarily collect the lint; When the condensed water and the heat exchange pipe condensation are opened at the same time, the condensed water flows down from the top, which can also have a flushing effect when condensing, which can flush the copper pipe of the heat exchange pipe and wash the lint adhered to the copper pipe down, and then drain away along the drain pipe; When the condensed water flows down, the condensed water passing through the copper pipe will temporarily hover, which has enough time to remove moisture and heat exchange, and the condensation of the copper pipe greatly increases the original condensation effect.

[0069] The scheme provided by the present application combines the heat exchange pipe with the rear air duct to realize air condensation, and can also cooperate with the condensed water to condense the air, which can effectively improve the air condensation efficiency of the clothes treatment equipment in the drying process, solve the problem of lint accumulation, and reduce the working energy consumption of the clothes treatment equipment.
