Description

  • The present invention relates to a clothes dryer, including an inner tub for accommodating clothes and an outer tub arranged around the inner tub. An inner tub wall has first holes in dense distribution to be in spatial communication with the outer tub. A cooling water supply device is connected with an outer tub wall to supply cooling water required for a drying process to an inner surface of the outer tub wall. The cooling water supply device includes a water outlet region.
  • A U.S. invention patent with the publication patent No. of US 6,279,357 B1 discloses a washer dryer. The washer dryer has a drum installed in an outer tub through a spider. A rear wall of the outer tub has recesses. Water flows to the rear wall of the outer tub from a water inlet device. In a drying mode, the drum rotates, and moist air leaves the drum and is agitated under the rotation of the drum. The flowing water is in contact with the moist air, so as to improve the condensing effect on the air before the air is heated and returns back to the drum along a circulation path.
  • A clothes dryer disclosing the features of the preamble of claim 1 is known from US2003/233854 A1 .
  • The present invention aims to make a clothes dryer have a relatively high heat exchange efficiency. The present invention provides a clothes dryer, including an inner tub for accommodating clothes and an outer tub arranged around the inner tub. An inner tub wall has first holes in dense distribution to be in spatial communication with the outer tub. A cooling water supply device is connected with an outer tub wall to supply cooling water required for a drying process to an inner surface of the outer tub wall. The cooling water supply device includes a water outlet region. The inner surface of the outer tub wall has a hydrophilically treated first region below the water outlet region, and the rest of the inner surface of the outer tub wall is a hydrophobic second region. A relatively large portion of an inner surface of an inner tub wall is hydrophobic to reduce residues of foam and washing water, and meanwhile, facilitate cleaning, thus being more sanitary. However, after falling onto the surface of the hydrophobic inner tub wall, cooling water may flow in a cylindrical trickle form, which leads to a small contact area with process air involved in drying, resulting in low heat exchange efficiency. After the first region is hydrophilically treated, the cooling water flows out of the water outlet region and flows down along the first region. In this case, water flow spreads along the inner surface of the outer tub wall to form a water film so as to have a relatively large contact area with the process air, and the heat exchange efficiency is also increased accordingly.
  • Hydrophilic treatment may include at least one of electrical spark etching, laser etching, spraying hydrophilic coating, and plasma treatment.
  • As one of embodiments, the water outlet region includes a group of second holes located on the outer tub wall, and the second holes are horizontally or obliquely arranged. The cooling water flows out of the second holes and forms a plurality of rows of water flow after contacting with the inner surface of the outer tub wall.

  • As one of the embodiments, the hydrophilic first region is located on an inclined or curved surface facing upwards.
  • The cooling water supply device may be connected with a cylindrical side wall of the outer tub, and the first region is located on the inner surface of the side wall of the outer tub.
  • The first region may be located at a lower position relative to a central axis of the outer tub.
  • The clothes dryer further includes a fan associated with the outer tub to propel the process air in the outer tub to flow, and a heating device associated with the outer tub to heat the process air.
  • An inlet and an outlet of an air passage are in fluid connection with a rear portion of the outer tub and a front portion of the outer tub, respectively, and the fan and the heating device are located in the air passage. The fluid connection may be referred to as that a wall of the air passage is directly or indirectly connected with the outer tub, such that the air passage is in spatial connection with the outer tub to form a fluid loop.
