Description

Detergent supply device and washing machine
Technical Field
The invention belongs to the technical field of washing machines, and particularly relates to a detergent supply device and a washing machine.
Background
At present, the washing machines on the market mainly include a drum washing machine in which an inner tub rotates about a horizontal axis and a pulsator washing machine in which an inner tub rotates about a vertical axis. The drum washing machine has the advantages of small abrasion to clothes, difficulty in winding among the clothes and small water consumption, and is deeply favored by users.
The detergent supply device is an essential component of the drum washing machine, is arranged between the water supply valve and the washing drum, and provides different clothes detergents or additives including washing liquid, bleaching agent, disinfectant, softener, washing powder and the like at different stages of clothes washing. The detergent powder is a solid additive, can be dissolved by the washing water and then directly washed into a washing drum, and the washing water is a liquid additive, and the liquid is required to be added at different washing stages, so the addition is usually realized by means of siphonage. Fig. 1 shows a dispenser structure of a detergent supply device commonly used in a drum washing machine, and the dispenser is a container including a plurality of detergent or additive feeding boxes/chambers. The dispenser shown in figure 1 comprises three chambers containing detergent or additives, wherein the "i" chamber is pre-wash in which washing powder or liquid detergent may be placed; wherein the cavity of the 'II' is main washing, and washing powder or liquid detergent can be placed in the cavity; the "iii" chamber is a softener dosing chamber which, by means of siphoning, allows the dosing of the softener, since it is liquid and needs to be added only at the time of rinsing. The siphon cap structure of the prior art installed on the chamber is shown in fig. 2, a siphon column is arranged on the siphon cap, the siphon column and the center of a siphon hole of the liquid detergent putting chamber are installed in alignment, as shown in an installation drawing shown in fig. 3, a gap is left between the inner wall of the siphon column and the outer wall of the siphon hole after the siphon column and the siphon hole are installed, as shown in a partial enlarged view shown in fig. 4. When the washing machine is running to a program requiring the addition of softener, water is fed into the A end of the softener chamber, and when the volume of liquid in the chamber increases to MAX level, a siphon phenomenon starts to occur, and the softener is thrown into the washing drum.
Although the prior art can realize that the additive is thrown on the washed clothes according to the set time, the gap between the inner wall of the siphon column and the outer wall of the siphon hole is very small, and the liquid close to the siphon area is the liquid detergent or the additive with relatively high concentration, so the liquid detergent in the area has insufficient dilution and is easy to block the siphon hole, and the siphon can not be smoothly carried out. If the detergent fails to enter the washing tub during the main washing or the pre-washing, it will enter the washing tub during the rinsing, causing secondary contamination of the laundry.
The invention is especially provided for solving the defects in the prior art.
