Washing additive feeding device

Abstract

The invention discloses a washing additive feeding device. The washing additive feeding device comprises a water box. A feeding box is arranged in the water box. At least one feeding cavity is formedin the feeding box, siphon columns are arranged in the feeding cavities, and a central flow passage and a peripheral flow passage which are independent to each other and extend vertically are arrangedin each siphon column. The top ends of the central flow passages and the peripheral flow passages are sealed by siphon covers and communicate with each other, and the bottom ends of the central flowpassages and the peripheral flow passages communicate with the water box and the feeding cavities correspondingly. A blocking rib sleeving the periphery of each siphon column is arranged in the corresponding feeding cavity, so that detergents in the feeding cavities and inflowing water flow through the blocking ribs and then flow to locations between the blocking ribs and the siphon columns. By arranging the circle of blocking ribs on the peripheries of the siphon columns, the siphon columns are isolated from the feeding cavities, the situation that liquid in the feeding cavities surges when the feeding cavities are pulled, the liquid level at the siphon columns rises and thus the siphon columns are triggered by mistake to perform siphoning is solved, and the purpose of preventing the siphon columns from being triggered by mistake to perform siphoning due to liquid surging is achieved.

Description

technical field [0001] The invention belongs to the field of laundry equipment, and in particular relates to a laundry feeding equipment applied to a washing machine. Background technique [0002] The washing and feeding device of the washing machine is installed on the body, and the washing and feeding device is provided with a feeding chamber or a liquid storage chamber, so that the user can manually add washing additives to the feeding chamber or the liquid storage chamber, and then use the washing machine's water flow to remove the additives. Added wash additives are flushed into the washer tub. Existing washing additives generally have two forms, one is solid powder washing powder, and the other is liquid laundry detergent, disinfectant, softener, etc. [0003] Powdered laundry detergent is usually put directly into the cavity, and the water can use the water to wash away the laundry detergent after the laundry starts; while liquid detergent additives need to be placed...

AI Technical Summary

Problems solved by technology

However, during the siphoning process, there will be detergent residue on the outer wall of the siphon column

[0006] In addition, when the viscosity of the washing additive in the injection chamber of the washing dosing device is extremely low and similar to that of water, when the liquid put into the dosing chamber reaches a certain amount, when the speed of the dosing box of the washing dosing device is relatively fast when it is pulled, it will cause The liquid in the dispensing chamber creates a turbulence that pushes the liquid level up, triggering a siphon so that undiluted detergent additives can cause misdosing
