Abstract: An automatic additive dispensing device includes: a liquid additive storage box, a measuring chamber communicating with the storage box, a pumping unit for pumping the additive into the measuring chamber, and a flushing water passage communicating with the measuring chamber. The measuring chamber measures the amount of an additive entering the measuring chamber; the flushing water passage introduces water into the measuring chamber, and then the additive pumped into the measuring chamber is discharged. The measuring chamber is flushed; and may directly or indirectly communicate with the liquid storage box. A one-way passage is arranged for flowing in a direction from the liquid storage box to the measuring chamber. By providing the simple one-way passage between the liquid storage box and the measuring chamber, flushing water can be prevented from being guided into the liquid storage box in the process of flushing the measuring chamber.

Abstract: A detergent dispensing device comprises a water box and a feeding box. A feeding chamber is in the feeding box, and has a stop plate for preventing water from flowing toward a water outlet. A siphon on the stop plate communicates one side with the other side, so that at an upstream side of the stop plate, a detergent and water flow fed to the water box from the feeding box is blocked by the stop plate and accumulated up to a water level for triggering a siphonic effect, and then flows to a downstream side along the siphon, and flows out from the water box via the water outlet. By the above arrangement, the detergent fed in the feeding chamber by a user is blocked by the stop plate, diluted by water, and then flows to the downstream side of the stop plate along the siphon.

Abstract: A detergent feeding device includes a water box and a feeding box in the water box. A downpipe is arranged inside the feeding box and vertically penetrating through an upper side and a lower side. An upper end and a lower end of the downpipe are respectively located at the upper side and the lower side of the feeding box, to guide residual water on a top surface of the feeding box to a bottom of the water box below the feeding box via the downpipe. Through this arrangement, residue of water on the top surface of the feeding box is avoided, and the residual water is prevented from leaking to the outside of the washing machine when the user pulls the feeding box out.

Abstract: An additive auto-feeding device, including a water supply flow channel; a liquid storage box containing an additive; a suction structure capable of sucking the additive to the flow channel and transferring the additive to a water outlet; and an anti-back suction device at a pressure adjusting opening of the flow channel. When water enters the flow channel, under the pressure effect of flowing water, the anti-back suction device closes the pressure adjusting opening; and when negative pressure is generated in the flow channel, the anti-back suction device opens the pressure adjusting opening for adjusting the pressure in the flow channel. The pressure adjusting device automatically adjusts opening and closing of an air hole to correspondingly adjust the pressure in a tube and avoid existence of negative pressure in the tube, thus achieving a backflow prevention function.
