Washing machine

Abstract

The invention provides a washing machine. The washing machine comprises a machine shell, a first roller, a second roller, a complete machine drainage pipe and a floating ball structure; the first roller is arranged in the machine shell, and a first drainage port is formed in the bottom of the first roller; the second roller and the first roller are arranged up and down, the second roller is located below the first roller, and a second drainage port is formed in the bottom of the second roller; the complete machine drainage pipe is connected with the first drainage port and the second drainage port and used for draining washing water in the first roller and the second roller out of the washing machine; and the floating ball structure is connected between the second drainage port and the complete machine drainage pipe and used for communicating or isolating the second drainage port and the complete machine drainage pipe. By arranging the floating ball structure, the second drainage port and the whole machine drainage pipe can be communicated and blocked according to needs, external water can be prevented from entering the second roller through the second drainage port, especially when the whole machine drainage pipe is blocked, washing water in the first roller can be prevented from entering the second roller, cross contamination is avoided, and the structure is simple and feasible, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of washing machines, in particular to a double cylinder washing machine. Background technique [0002] Washing machines have been widely used as household appliances in people's lives. Generally, a family only has one washing machine. With the improvement of people's quality of life, classified and healthy cleaning has become a lifestyle and pursuit. Users usually increase the number of washing machines. However, multiple washing machines cost a lot, take up a lot of space, and have high maintenance costs. Therefore, double-drum and multi-drum washing machines with more than double drums have emerged as the times require, realizing the washing of clothes in separate drums. [0003] At present, most of the double-tubular washing machines are drained from the bottom. When the position of the drain port set by the user is high, the washing machine cannot be used, which makes the scope of application of the wash...

[0002] Washing machines have been widely used as household appliances in people's lives. Generally, a family only has one washing machine. With the improvement of people's quality of life, classified and healthy cleaning has become a lifestyle and pursuit. Users usually increase the number of washing machines. However, multiple washing machines cost a lot, take up a lot of space, and have high maintenance costs. Therefore, double-drum and multi-drum washing machines with more than double drums have emerged as the times require, realizing the washing of clothes in separate drums

[0003] At present, most of the double-tubular washing machines are drained from the bottom. When the position of the drain port set by the user is high, the washing machine cannot be used, which makes the scope of application of the washing machine small, unable to meet the needs of different users, and makes the user experience poor; When the water outlet of the whole machine is blocked, the water discharged from the upper drum enters the lower drum and causes cross-contamination. The use of a one-way valve can prevent water from entering the lower drum, but the cost of setting the one-way valve is high, it needs to be controlled separately, and the circuit is complicated
