Description

Throwing system and washing machine Technical Field The utility model relates to the technical field of washing machines, in particular to a throwing system and a washing machine with the same. Background The washing machine is provided with a delivery system for delivering washing fluid into a washing tub of the washing machine, and the delivery system can simultaneously deliver the washing fluid mixed with additives (laundry detergent, softener and the like) into the washing tub and spray water with silver ions into the washing tub. In the prior art, the silver ion module is directly arranged in the spraying passage, all spraying water passes through the silver ion module, and the water flow demand of spraying into the barrel is actually larger than that of the silver ion releasing passage, if the water flow flowing through the silver ion releasing passage is overlarge in a specified time period of releasing washing fluid, the electrolysis of silver flakes and water in the silver ion module is not completed, the electrolysis efficiency of the silver ion module is affected, and therefore the problem of non-ideal concentration of silver ions released into the washing barrel is caused. Disclosure of utility model The present application aims to provide a delivery system for delivering a washing fluid into a washing tub of a washing machine and a washing machine having the same, so as to solve or alleviate at least some of the problems of the prior art. The application provides a delivery system for delivering washing fluid into a washing barrel of a washing machine, which comprises a water inlet valve assembly connected with an external water source, a water inlet passage with one end communicated with the water inlet valve assembly, a first diversion structure arranged in the water inlet passage, and a silver ion delivery passage which is arranged in parallel relative to the water inlet passage in a manner of being communicated with the first diversion structure, wherein a silver ion module is arranged in the silver ion delivery passage, the water inlet passage is provided with a converging structure, and the silver ion delivery passage and the water inlet passage are converged at the converging structure and are communicated into the washing barrel. According to the technical scheme, a part of water entering the water inlet passage from the water inlet valve assembly continues to circulate along the water inlet passage, the other part of water is shunted by the first shunting structure to enter the silver ion throwing passage and electrolyzes with the silver ion module arranged in the silver ion passage to generate silver ions, and part of water with the silver ions and water continuing to circulate along the water inlet passage are converged at the converging structure and then are thrown into the washing barrel together, so that the water quantity passing through the silver ion module is matched with the electrolysis efficiency in a fixed time period for throwing washing fluid, and silver flakes and water can be fully electrolyzed, so that the concentration of the silver ions thrown into the washing barrel can reach the required concentration. In an alternative technical scheme, the first diversion structure is a first restricted orifice, and the water inlet passage is provided with a second restricted orifice communicated with the confluence structure. According to the technical scheme, the water quantity which is shunted into the silver ion throwing passage is controlled by the first limiting hole and the second limiting hole, so that the water flow passing through the silver ion module is further controlled under the condition that the water flow which is thrown into the washing barrel is unchanged, and the problem that when the water flow passing through the silver ion module is overlarge and the electrolysis efficiency is not matched, part of silver pieces and water are not electrolyzed, and the concentration of silver ions thrown into the washing barrel is not ideal is avoided. In an alternative technical scheme, the ratio of the flow area of the first flow limiting hole to the flow area of the second flow limiting hole is more than 1 and less than 3. According to the technical scheme, the water flow rate of the silver ions which flow through the silver ion module and are electrolyzed with the silver ion module is controlled more accurately while the water flow rate of the water put into the washing barrel can meet the total water inflow requirement. In an alternative solution, either one of the first restriction orifice and the second restriction orifice is provided as an adjustable aperture structure. According to the technical scheme, the aperture of the first limiting hole and/or the aperture of the second limiting hole are/is adjusted according to the current running condition of the washing machine, so that the concentration of silver ions in water put into the washing barrel is adjusted, and
