The clothes drying mode is slow in moisture evaporation, long in clothes drying waiting time and poor in user experience.

In order to improve the efficiency of drying the clothing, shorten the time of waiting for the clothing to dry, this application provides a dryer. Referring to fig. 1, the dryer includes a controller 100, a sealing drum 200, a heating device 300, and a negative pressure suction device 400. The sealed drum 200 has an inner cavity capable of storing the laundry, that is, the sealed drum 200 is opened to put the laundry to be dried, the sealed drum 200 is sealed after the laundry is put in, and the external air cannot enter the inner cavity of the sealed drum 200. The heating device 300 is disposed on the sealing drum 200, and the heating device 300 is connected to the controller 100 for heating by the controller 100. The sealing roller 200 is further provided with a negative pressure exhaust port 211 communicated with the inner cavity, the negative pressure suction device 400 is communicated with the inner cavity of the sealing roller 200 through the negative pressure exhaust port 211, and the negative pressure suction device 400 is connected with the controller 100 and is used for providing negative pressure to the inner cavity of the sealing roller 200 under the action of the controller 100. That is, the air pressure of the cavity of the sealing drum 200 is less than the air pressure outside the sealing drum 200 by the suction of the negative pressure suction device 400.
