[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Please refer to Figures 1 to 4 The utility model provides a drying machine, which comprises: a machine body, a drum 1 arranged in the machine body, a heat recovery core 6 arranged on one side of the drum 1, an evaporator 5 and a dehumidification heat recovery device 4;

[0025] The heat recovery core 6 and the evaporator 5 form a secondary energy recovery mechanism, and a centrifugal fan 2 is also provided in the body, and the centrifugal fan 2 is provided between the dehumidification heat recovery device 4 and the drum 1;

[0026] An air circulation path is provided in the machine body, and the air circulation path passes through the drum 1, the secondary energy recovery mechanism and the dehumidification recovery device in sequence. The air inside the dryer enters the drum 1 from the top of the drum 1 after passing through the secondary energy recovery mechanism, and after being dried with the clothes in the drum 1, enters the secondary energy recovery mechanism from the lower end of the drum 1 for circulation.

[0027] Furthermore, a compressor 7 is arranged between the secondary energy recovery mechanism and the drum 1. The humid air emitted from the lower end of the drum 1 passes through the compressor 7 and is input into the heat recovery core 6. After passing through the evaporator 5, it passes through the heat recovery core 6 again and is output to the dehumidification recovery device, and is output into the drum 1 under the drive of the centrifugal fan 2.

[0028] Specifically, the dehumidification heat recovery device 4 is provided with a dehumidification fan 8, and the dehumidification fan 8 is connected to the dehumidification heat recovery device 4. A dehumidification air duct 33 is also provided in the machine body, one end of the dehumidification air duct 33 is connected to the dehumidification fan 8, and the other end of the dehumidification air duct 33 extends to the outside of the machine body. The dehumidification fan 8 extracts moisture in the dehumidification heat recovery device 4 and discharges it to the outside of the dryer through the dehumidification air duct 33.

[0029] Furthermore, a fresh air valve 31 and a fresh air duct 32 are provided in the machine body. The fresh air duct 32 is connected with the dehumidification heat recovery device 4 based on the fresh air valve 31. When the dryer completes the drying operation of the clothes, the dehumidification heat recovery device 4 inhales external air based on the fresh air duct 32, and extracts moisture from the external air based on the dehumidification fan, so that the dry air can perform heat exchange with the clothes and quickly cool down the dried clothes.

[0030] Furthermore, based on the fresh air duct 32, a fresh air dehumidification system is formed in the machine body. When the humidity in the machine body is high, the dehumidification fan 8 and the fresh air valve 31 are started at the same time, which can quickly reduce the humidity of the circulating air inside the dryer. When the dryer completes the drying operation, the humidity of the clothes inside the dryer can be reduced through the fresh air dehumidification system, achieving a rapid cooling effect.

[0031] Specifically, a guide rail automatic dust collector 9 is provided on one side of the drum 1; the guide rail automatic dust collector 9 includes a bag filter 93 and a dust collecting peg, and the dust collecting peg is arranged on the bag filter. The guide rail automatic dust collector 9 also includes a dust collector main unit 91 and an electric guide rail 94; the dust collector main unit 91 is driven and connected to the electric guide rail 94, and the electric guide rail 94 is arranged below the bag filter 93, and the dust collecting peg is slidably fitted on the electric guide rail 94. The dust collector main unit 91 is used to drive the dust collecting peg to move on the electric guide rail 94, and the dust collector main unit drives the dust collecting peg 92 on the electric guide rail 94 to move on the bag filter 93, so that the dust collecting peg 92 cleans the cotton wool on the clothes on the bag filter 93.

[0032] Furthermore, a pressure difference switch sensor is provided on the bag filter 93, and the pressure difference on both sides of the bag filter 93 is detected based on the pressure difference switch sensor. When the cotton wool accumulated in the bag filter 93 reaches a certain level, a large pressure difference is formed on both sides of the bag filter 93, thereby triggering the pressure difference switch sensor, so that the guide rail automatic dust collector 9 is started to remove dust from the bag filter 93.

[0033] Furthermore, a condenser 3 is provided between the centrifugal fan 2 and the dehumidification heat recovery device 4, and the condenser 3 is used to condense and dehumidify the air entering the drum 1, so that the air entering the drum 1 is dry air, thereby taking away moisture in the clothes.

[0034] Specifically, the dryer adjusts the working efficiency of the dryer through frequency conversion control, so that the dryer has the effects of fast heating and precise temperature control. Ozone and ultraviolet sterilization lamps are arranged inside the dryer, and clothes are sterilized and disinfected based on the ozone and the ultraviolet sterilization lamps.

[0035] The utility model provides a dryer, which forms a secondary energy recovery mechanism through a heat recovery core 6 and the evaporator 5. While the dryer is dehumidifying, the heat in the dehumidification process can be effectively recovered to achieve energy-saving effects. The evaporator 5 also dehumidifies the humid air returned from the drum 1 side, reducing energy loss and improving the working efficiency of the dryer.
