  • This patent application claims benefit to Korean Patent Application No. 10-2017-0074619 filed Jun. 14, 2017, with inventor Jong Jin Lee, and whose specification is incorporated by reference herein.
  • TECHNICAL FIELD
  • The present disclosure relates to a wall mounted washing machine and a water supply valve assembly thereof.
  • BACKGROUND
  • A washing machine is device for separating contaminants from laundry using wash water and detergents, wherein the contaminants may be separated from the washed fabric by the chemical action of the detergent dissolved in the wash water and the mechanical action of the wash water and an inner basket. Washing machines may be categorized into several types, including, a top loading type washing machine, a front loading type washing machine, and a combined type washing machine combining the top loading type and the front loading type, depending on the way the laundry is loaded.
  • In recent years, wall mounted washing machines have been introduced, which may be installed in narrow spaces such as bathrooms and toilets, for instance. In general, the wall mounted washing machines employ the front loading type for miniaturization.
  • For example, a wall mounted washing machine may include a cabinet that forms an exterior, a tub provided in the cabinet filled with wash water, a drum rotatably installed in the tub and accommodating the laundry, a drive unit providing power to the drum, a water supply unit for supplying the wash water to the tub, and a drain unit for discharging the wash water from the tub to the outside of the cabinet.
  • In the prior art, the wall-mounted washing machine has a plurality of pipe lines or electromagnetic valves installed for the respective pipe lines for supplying detergents or conditioners to the inside of the tub at predetermined times.
  • For example, a wall-mounted washing machine of the prior art is further provided with pipe lines for supplying detergent liquid made by mixing detergents into water inside of the tub, and pipe lines for supplying a conditioner liquid made by mixing conditioners with water inside of the tub.

  • The water flowing into the interior space of the drying duct 791 meets the internal flow air of the drying duct 791 of the drying unit 790. At that time, the inside air of the drying duct 791 and the inflow water are mutually heat exchanged.
  • The humidity of the air inside the drying duct (791) becomes condensed water through heat exchange. Thereafter, the condensed water moves along the surface of the drying duct 791, and then is discharged to the outside through the drain portion of the drying duct 791. On the other hand, the internal dry air of the drying duct 791 with moisture removed may be supplied to the inside of the drum 600, and thus the laundry inside the drum 600 may be efficiently dried.
  • The wall-mounted washing machine and the water supply valve assembly thereof according to the embodiments of the present disclosure are advantageous in that a connection may easily and precisely be made between the pipe (which is a supply flow path) and a fitting.
  • Further, there is an advantage that space between a cabinet corresponding to an external article of the washing machine and an internal article of the washing machine may be efficiently used.
  • Further, there is an advantage that functions of the washing machine (for example, a drying function, a function of spraying water directly to laundry, etc.) may be easily added or extended.
  • In addition, there is an advantage that due to increased functionality of the washing machine, required pipe and fitting installation may be performed very easily.
  • The above description is merely illustrative of the technical idea of the present disclosure and various changes and modifications may be made without departing from the essential characteristics of the present disclosure. Therefore, the embodiments described in the present disclosure are not intended to limit the scope of the present disclosure, but are intended to illustrate and not limit the scope of the present disclosure. The scope of protection of the present disclosure should be construed according to the following claims, and all technical ideas which are equivalent or equivalent thereto should be interpreted as being included in the scope of the present disclosure.
