Problems solved by technology

[0003] Taking the household drum washing machine as an example, because the washing time of the drum washing machine is long, in order to save time and make full use of washing resources, the existing households basically wash the clothes of adults and children together. However, this washing method cannot guarantee Hygienic and clean children's clothes; moreover, considering the impact of environmental pollution, the drying process will increase the bacterial contamination on the clothes. However, the current all-in-one washing and drying machines mostly use water condensation or direct discharge to dry clothes. Among them, The water-condensing type consumes a lot of energy and takes a long time to dry; the hot and humid gas generated by the direct-exhaust type has a great impact on the indoor air environment and reduces indoor comfort

example 1

[0045] Example 1, the lower cylinder is currently in a washing or rinsing state.

[0046] After the hot and humid air flow of the upper cylinder enters, it heats the washing water or rinsing water and the laundry, so that the laundry is in a warm water environment, accelerates the movement of water ions in it, and effectively improves the washing or rinsing performance of the laundry; moreover, it also It can effectively reduce the electric energy used for heating the water temperature.

example 2

[0047] Example 2, the lower cylinder is currently in a dehydration state.

[0048] The current drum washing machine has various functions. Among them, steam care can eliminate the peculiar smell and wrinkles of the clothes, and can also make the clothes material soft. However, to achieve this steam care function, a steam generating device needs to be added. By adopting the drum washing machine in this application, not only can the clothes be sorted and washed, and the clothes in the upper cylinder can be dried, but also, the high-temperature airflow discharged after drying does not need to be directly discharged from the washing machine, but is transported to the lower cylinder. In the body, steam care is performed on the clothes being washed in the lower cylinder, so that the upper and lower cylinders work together, not only to achieve classified washing, but also to avoid the direct discharge of hot and humid air generated by the upper cylinder from affecting the environment,...

example 3

[0049] Example 3, the lower cylinder is currently in a non-working state.

[0050] After the hot and humid air flow of the upper cylinder enters, it will condense on the inner cylinder and outer cylinder wall of the lower cylinder, and the condensed water will adhere to the inner cylinder. Before the body drying is completed, the lower cylinder should be controlled for proper dehydration. Generally, the dehydration speed is 180rpm-400rpm, and the dehydration time is 1-3min. All the air is dry and hot, which can realize the drying of the inner cylinder and the outer cylinder wall of the lower cylinder, ensure the cleanliness of the lower cylinder, and avoid the impact of bacterial growth or liquid drop erosion on the life of the inner cylinder.

[0051] The above scheme is mainly aimed at the situation where there are few clothes on the upper cylinder. However, considering that the volume of the upper cylinder may be larger and there are more clothes to be dried, then, after th...

Abstract

The invention relates to the technical field of washing machines and in particular provides a drum washing machine which can achieve the effects of partitioned washing of different kinds of clothes and effective drying. The drum washing machine comprises a washing machine body, and a first drum body and a second drum body which are embedded in the washing machine body; the first drum body and the second drum body communicate with each other via a pipe; a drying device is arranged in the first drum body; when the drying device works, damp and hot gas generated by the first drum body enters the second drum body via the pipe and is discharged out of the drum washing machine after heat exchange and condensation by the second drum body. Thus, clothes can be washed in a partitioned manner; indoor environment pollution caused by direct discharge of damp and hot gas is prevented; energy consumption is reduced; damp and hot gas can be used for steam nursing for clothes in the second drum body, so that the washing quality is improved.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a drum washing machine. Background technique [0002] At present, with the rapid development of science and technology, people are better pursuing a healthy and high-quality lifestyle, especially the demand for the quality of household appliances in daily life is gradually increasing. [0003] Taking the household drum washing machine as an example, because the washing time of the drum washing machine is long, in order to save time and make full use of washing resources, the existing households basically wash the clothes of adults and children together. However, this washing method cannot guarantee Hygienic and clean children's clothes; moreover, considering the impact of environmental pollution, the drying process will increase the bacterial contamination on the clothes. However, the current all-in-one washing and drying machines mostly use water condensation or direct ...
