Description

Detergent supply device and washing machine

Technical field

The invention belongs to the technical field of washing machines, and in particular relates to a detergent supply device and a washing machine.

Background technique

At present, the washing machine on the market mainly comprises a drum washing machine in which the inner cylinder rotates around a horizontal axis and a pulsator washing machine in which the inner cylinder rotates around a vertical axis. Among them, the drum washing machine has little wear on the clothes, the clothes are not easily entangled, and the water consumption is small, which is favored by the users.

The detergent supply device is an indispensable component of the drum washing machine. It is disposed between the water supply valve and the washing tub, and provides different laundry detergents or additives at different stages of laundry washing, including washing liquid, bleach, disinfectant, Softener, washing powder, etc. Among them, in addition to the washing powder is a solid additive, it can be directly washed into the washing tub by means of washing water, and the others are liquid additives. Since these liquids need to be added in different washing stages, the addition is usually achieved by means of siphoning. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a dispenser structure of a conventional detergent supply device for a drum washing machine, which is a container including a plurality of detergent or additive dispensing boxes/chambers. The dispenser shown in Figure 1 comprises three chambers containing detergent or additives, wherein the "I" chamber is pre-washed with detergent or liquid detergent placed therein; wherein the "II" chamber is the main wash, The detergent powder or liquid detergent can also be placed therein; the "III" chamber is the softener delivery chamber. Since the softener is liquid and needs to be added during rinsing, the chamber needs to be acted upon by siphoning. The structure of the prior art siphon cap installed on the chamber is as shown in FIG. 2. The siphon cap is provided with a siphon column, and the siphon column and the center of the siphon hole of the liquid detergent dispensing chamber are aligned and installed, as shown in FIG. The installation diagram, after installation, has a gap between the inner wall of the siphon column and the outer wall of the siphon hole, as shown in a partial enlarged view of FIG. When the washing machine is run to the procedure where the softener is added, water is introduced into the A end of the softener chamber. When the liquid volume in the chamber is increased to the MAX surface, the siphon phenomenon begins to occur and the softener is discharged into the washing tub.

The prior art solution can achieve the application of the additive to the washed laundry according to the set time, but the gap between the inner wall of the siphon column and the outer wall of the siphon hole is very small, and the liquid near the siphon region is concentrated. Relatively large liquid detergents or additives, so the liquid detergent in this area is insufficiently diluted and is prone to block the siphon hole, resulting in the smooth operation of the siphon. If the detergent fails to enter the washing tub during the main wash or prewash, it will enter the wash tub during rinsing, causing secondary contamination of the laundry.

In order to solve the deficiencies in the prior art, the present application is specifically filed.
