Definitions

  • the present disclosure relates to the technical field of clothes treatment, and in particular to a clothes treatment device such as a clothes dryer and a washer-dryer.
  • a related art discloses a washer-dryer. By adding a blower between an outer tub and a case, heat exchange between the outer tub and the outside air is improved, so that the outer tub is cooled, and based on a temperature difference between the inside and outside of the outer tub, the hot and humid air in the tub condenses, thus resulting in a high cost and a poor heat exchange effect.
  • an objective of the present disclosure is to provide a clothes treatment device which has a simpler structure and high drying efficiency.
  • a vent is provided and serves as an inlet/outlet of airflow to ensure a dynamic balance of air pressure between the clothes treatment chamber and the outside during the operation of the clothes treatment device.
  • a vent serves as an inlet/outlet of airflow to ensure a dynamic balance of air pressure between the clothes treatment chamber and the outside during the operation of the clothes treatment device.
  • part of the hot and humid air can overflow from the vent under the action of an air pressure difference, thus improving the drying efficiency
  • the outside air can enter the clothes treatment chamber from the vent to participate in the circulation of the airflow, thereby realizing exchange of the hot and humid air with the outside air.
  • the clothes treatment device does not form a through airflow channel during the drying process, thereby ensuring quick heating-up in the tub assembly in the initial stage of the drying process and reducing the risk of overfoaming.
  • a waterproof and air-permeable member is provided at the vent, thereby preventing water and foam in the clothes treatment chamber from overflowing from the vent, and ensuring that the air in the clothes treatment chamber can be discharged from the vent to the outside.
  • the flow area of the air outlet is greater than 8000 mm 2 .
  • an orthographic projection of the air outlet on an imaginary horizontal plane passing through a central axis of the tub assembly deviates from the central axis of the tub assembly.
  • a filter assembly and a spraying member are provided inside the connecting base, the filter assembly is configured to filter air discharged from the air outlet, and the spraying member is located above the filter assembly.
  • the filter assembly includes a filter screen and an annular connecting frame, and the filter screen is mounted in the connecting base through the annular connecting frame.

  • an outer surface of the air channel shell is provided with a mounting lug
  • the connecting base and the air channel shell are connected by a fastener passing through the connecting lug and the mounting lug.
  • the vent is provided to a side of the connecting base.
  • the air channel shell includes: an air channel base arranged above the tub assembly and the connecting base; an air channel cover plate covering a part of the air channel base; and a blower cover plate covering the other part of the air channel base, a fan of the blower being arranged between the blower cover plate and the air channel base.
  • a side wall of the mounting recess is provided with a plurality of spacer ribs arranged at intervals along a circumferential direction of the mounting recess for spacing at least a part of the driving motor apart from the side wall of the mounting recess.
  • Each of the spacer ribs includes an inner rib section and an outer rib section connected to each other, the inner rib section is located in the mounting recess and extends along a depth direction of the mounting recess, and the plurality of outer rib sections are arranged in a radial way and located outside the mounting recess.

  • the air channel assembly has a vent 2141 in communication with the air outlet 102 and the outside, and the vent 2141 is located above the air outlet 102.
  • the vent 2141 is provided and serves as an inlet/outlet of airflow to ensure a dynamic balance of air pressure between the clothes treatment chamber 121 and the outside during the operation of the clothes treatment device 100.
  • the air pressure in the clothes treatment chamber 121 increases, part of hot and humid air can overflow from the vent 2141 under the action of an air pressure difference, thus improving the drying efficiency;
  • the outside air can enter the clothes treatment chamber 121 from the vent 2141 to participate in the circulation of the airflow, thereby realizing exchange of the hot and humid air with the outside air.
  • the clothes treatment device 100 does not form a through airflow channel during the drying process, thereby ensuring quick heating-up in the tub assembly in an initial stage of the drying process and reducing the risk of overfoaming.
  • the air inlet 101 is located at a front part of the tub assembly 10
  • the air outlet 102 is located at a rear part of the tub assembly 10.
  • the air inlet 101 and the air outlet 102 are spaced apart in the axial direction of the tub assembly 10.
  • a distance between the air inlet 101 and the air outlet 102 can be increased, i.e., a distance between the air channel inlet and the air channel outlet 2104, can be increased.
  • the flowing time of moist air (discharged from the clothes treatment chamber 121) in the air channel 2101 can be increased, the heating time of the heating member 22 to the airflow is prolonged, and the moist air just discharged can be prevented from being sucked in immediately, which is beneficial to improving the drying efficiency.
  • an orthographic projection of the air outlet 102 on an imaginary horizontal plane X passing through a central axis of the tub assembly 10 deviates from the central axis of the tub assembly 10. Therefore, by effectively using the position of the tub assembly 10 in the circumferential direction, a distance between the air inlet 101 and the air outlet 102 can be increased, which is beneficial to improving the drying efficiency.
