Abstract

An additive dispensing device (100) and a washing machine are provided. The additive dispensing device (100) comprises: a water supply flow path (1), configured to allow inlet water entering the additive dispensing device (100) to flow therethrough; and a dispensing unit, configured to dispense an additive into the water supply flow path (1). A plurality of Venturi tubes (19) arranged in parallel are provided on the water supply flow path (1). A negative-pressure suction port (191) of each Venturi tube (19) is communicated with external atmosphere. Under the action of an additive mixed liquid flowing through each Venturi tube (19), negative pressure is formed at the negative-pressure suction port (191), so that external air enters the Venturi tube (19) from the negative-pressure suction port (191) and is mixed with the additive mixed liquid flowing through the Venturi tube (19), thereby exciting the additive mixed liquid to generate foam and form a mixture containing foam. By providing the plurality of Venturi tubes (19) arranged in parallel on the water supply flow path (1), all additive solution flowing therethrough is excited by pumped air, thereby increasing the foaming amount of the additive mixture dispensed outwardly and improving the washing effect on laundry.
