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 A washing machine is provided with a delivery system for delivering a washing fluid into a washing tub of the washing machine, and the delivery system can deliver the washing fluid mixed with an additive (a liquid detergent, a softener, etc.) into the washing tub. In order to solve the problem of pressure rise in the washing barrel, in the prior art, the air in the washing barrel is discharged through the exhaust pipe communicated with the additive feeding passage arranged in the feeding system, but when an external water source enters the feeding system through the water inlet valve assembly, water enters the exhaust pipe through the additive feeding passage, and the air discharging effect in the washing barrel is affected. 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 washing fluid throwing system for throwing washing fluid into a washing barrel of a washing machine, which comprises a water inlet valve assembly connected with an external water source, an additive throwing passage, a water outlet groove, an exhaust passage, an exhaust pipe, an exhaust port and an exhaust pipe, wherein one end of the additive throwing passage is connected with the water inlet valve assembly, the water outlet groove is arranged in a mode corresponding to the additive throwing passage and communicated with the additive throwing passage, the bottom of the water outlet groove is provided with a water outlet, washing fluid is supplied into the washing barrel through the water outlet, the exhaust passage is arranged in a mode isolated from the additive throwing passage and corresponds to the water outlet groove, one end of the exhaust passage is provided with an exhaust port and communicated with the water outlet groove through the exhaust port, and one end of the exhaust passage is communicated with the exhaust passage through an air vent, and the other end of the exhaust passage is communicated with the exhaust pipe in the washing barrel. According to this technical scheme, when washing fluid is put into the washing tub through additive put-in passageway and play basin, the pressure in the washing tub risees, and the inside air of bucket gets into the exhaust passage through the blast pipe under the effect of high pressure to in the play basin through the gas vent that sets up in the exhaust passage. By arranging the exhaust passage isolated from the additive putting passage, the problem that the ventilation performance of the washing barrel is influenced by the fact that the additive putting passage enters the exhaust pipe when an external water source enters the putting system in the prior art is avoided. In an alternative solution, the exhaust passage includes a first exhaust passage and a second exhaust passage that are mutually communicated, and the first exhaust passage and the second exhaust passage are disposed to intersect at an angle to form the bubble chamber. According to the technical scheme, the first exhaust passage and the second exhaust passage are intersected in a certain angle mode to form the foam containing cavity, when the pressure in the washing barrel rises to enable air in the barrel and part of detergent foam to enter the exhaust passage through the exhaust pipe, the detergent foam is temporarily contained in the foam containing cavity and further enters the water outlet groove through the foam containing cavity, and therefore the problem that excessive detergent foam is accumulated in the exhaust pipe and affects the ventilation performance of the washing barrel is avoided. In an alternative technical scheme, the exhaust port comprises a first exhaust port and a second exhaust port, wherein the first exhaust port opening is arranged at one end of the first exhaust passage far away from the air port, and the second exhaust port opening is arranged at one end of the second exhaust passage far away from the air port. According to the technical scheme, the first exhaust port and the second exhaust port are both arranged at the positions far away from the air vent, so that the problem that the ventilation performance of the washing barrel is affected due to the fact that local vortex is formed at the air vent by the liquid for the washing agent with the faster flow speed flowing upwards through the exhaust pipe under the action of high pressure in the washing barrel, or part of washing agent foam is gathered at the position near the air vent after entering the exhaust passage through the exhaust pipe to block the first exhaust port or the second exhaust por
