Negative pressure suction structure, dispensing device and washing machine

Abstract

The present application provides a dispensing device and a washing machine. The dispensing device includes: a dispensing box, having a washing powder chamber for dispensing washing powder; a water tank and a water supply pipeline. Water flowing into the water tank by the dispensing device is used to flush washing powder in the washing powder chamber into the water tank to form a washing powder solution; a negative pressure suction structure is disposed in the water supply pipeline, so that a negative pressure is generated by the water flow flowing through the water supply pipeline; and the negative pressure suction structure is connected with the water tank, so that the washing powder solution in the water tank is sucked into the water supply pipeline by the negative pressure. Through the above arrangement, the washing powder solution to be dispensed is sucked by using the water flowing through the water supply pipeline separately arranged, to realize the effect of automatically sucking and dispensing the washing powder solution. Thereby the washing powder solution with a high concentration is used to directly wash laundry in the washing drum.
