Washing feeding device and washing machine

Abstract

A washing feeding device includes a water box, and a feeding box installed in the water box; at least one feeding chamber is arranged in the feeding box. A baffle board is pivoted and installed in the feeding chamber for preventing water from flowing to a water outlet. A gap portion is formed on the baffle board, and an inlet water flow of the water box flows to the gap portion of the baffle board that is open when the baffle board is pivoted, and the inlet water flow washes a bottom wall of the feeding chamber below the baffle board after passing through the baffle board from the gap portion, and opening the baffle board.
