Definitions

  • the present disclosure relates to the field of household appliance technologies, and more particularly, to a dishwasher.
  • dishwashers are usually equipped with water heating devices to improve efficiency of washing dishes. Heating water for washing can not only wash away scraps from dishes by high-temperature water for washing but also brings heat to the dishes.
  • a dishwasher system is therefore able to obtain high cleaning efficiency and a high drying rate in a short washing time.
