Automatic detergent adding system and washing machine

Abstract

An automatic detergent adding system and washing machine. The automatic detergent adding system comprises a detergent container containing detergent, and an automatic detergent feeding device connected with the detergent container, and also comprises a pipe joint separately communicating with the automatic detergent feeding device and a water inlet pipeline, a water conduit communicating with an outer drum, and the pipe joint is connected with the water conduit. The detergent and tap water in the water inlet pipeline are converged in the pipe joint and the water conduit and flow to the outer drum, so that a water injection slot component in an original washing machine is omitted, the structure is simple, a series of problems caused by existence of the water injection slot component are avoided. The water and the detergent are mixed before washing, and thus washing efficiency is improved.
