Embodiment 1

[0036] Such as Figure 7 As shown, the inlet of the drain valve 4 in this embodiment is connected to the first drain port 2, the outlet of the drain valve 4 is connected to the drain pipe of the washing machine, and the inlet of the circulation pump 6 is directly inserted into the second drain port 3. The circulating pump is connected to the bottom of the outer barrel through bolts or screws, and a sealing ring is provided at the joint, and the water inlet of the circulating pump is perpendicular to the bottom of the outer barrel. The outlet of the circulation pump 6 is connected with the internal circulation pipeline. The water inlet of the circulating pump 6 is directly connected to the second drain port 3, and the washing water flows through the second drain port 3, the circulating pump 6, and the circulation pipeline and then sprays into the inner tub through the spray structure, so as to realize the internal circulation of the water flow, so that in the washing When the ...

Embodiment 2

[0038] Such as image 3 , Figure 4 , Figure 5 , Figure 6 As shown in the embodiment, a drain valve 4 is provided at the first drain port 2, which is connected to the drain pipe through the drain valve 4, and a connecting pipe 5 is provided at the second drain port 3, and the inlet of the connecting pipe 5 is connected to the second drain port. The drain port 3 is connected, the water outlet of the connecting pipe 5 is connected with the water inlet of the circulation pump 6, and the water outlet of the circulation pump 6 is connected with the internal circulation pipeline. In this way, the washing water passes through the second drain port 3, the connecting pipe 5, the circulation pump 6, and the circulation pipeline and then sprays back into the inner bucket through the spray structure, so as to realize the internal circulation of the water flow, and the beating of the water flow can form more abundant foam. It is conducive to the penetration of foam and washing liquid ...

Embodiment 3

[0041] The washing machine described in this embodiment is a self-cleaning washing machine. A cleaning ball is provided between the inner tub and the outer tub 1 to clean the tub wall between the inner and outer tubs. The drain valve is provided with a filter structure to filter the cleaning ball to avoid cleaning. The balls are discharged with the drain pipe, and a chamber is set on the drain valve as the cleaning ball storage room 7. When dehydration or the washing machine is not in use at ordinary times, the cleaning balls are stored in the cleaning ball storage room 7 through the blocking of the filter structure. The filter structure can be Filters or retaining ribs.

[0042] The second drain port 3 can be a circular drain port, and a filter structure is also provided in the connecting pipe 5 to filter the cleaning balls, so as to prevent the cleaning balls from entering the circulating pump and being broken, or damaging the circulating pump.

[0043] The second drain port...

Abstract

The invention relates to a washing machine with an internal circulation system. The washing machine comprises an external barrel, an internal barrel arranged in the same axis with the external barrel, a water drainage system and an internal circulation pipeline. The bottom of the external barrel is provided with at least two water drainage ports. One of the water drainage ports is communicated with the water drainage system and the other one of the water drainage ports is communicated with the internal circulation system. The washing machine with the internal circulation system has following beneficial effects: by additionally arranging a water drainage port in the bottom of the external barrel, the water drainage system is separated from the circulation system; due to the fact that a water drainage pipeline is independent from the internal circulation pipeline, pipelines are prevented being intersected so that space is saved for wiring of circuits at concentration positions; universality of a water drainage valve is achieved; cost is decreased; and technology is simplified.

Description

technical field [0001] The invention relates to the field of washing equipment, in particular to a washing machine with an internal circulation system. Background technique [0002] Now some washing machines are equipped with an internal circulation spray function. When washing, the internal washing water is pumped into the spray structure and then sprayed into the washing bucket, so that the beating of the water flow can form more abundant foam, which is beneficial to the foam and washing liquid. Penetrating through clothes is also conducive to the mixing of clothes and washing water, separating the stains on clothes and improving the washing rate. When rinsing, the internal rinsing water is pumped into the spray structure and then sprayed into the washing tub, which is good for clothes and washing. Water mixes to increase rinsing efficiency. [0003] The existing washing machine with internal circulation spray function is provided with a circulating water outlet on the dr...
