A space formed between the second container 200 and the first container 100 stores not only liquid for washing laundry but also washing water for introducing the liquid into the washing container. Since the washing water enters the second container 200 through the water inlet pipe 230, a passage for circulation of the washing water is formed between the inner wall of the second container 200 and the outer wall of the first container 100, and under the flowing action of the washing water, the washing water guides the liquid for washing to the liquid outlet hole 220 and is conveyed into the washing container through the liquid outlet hole 220, thereby realizing the circulation of the washing water and facilitating the introduction of the liquid into the washing container. Wherein the liquid functions in multiple ways, for example, the liquid comprises laundry detergent; as another example, the liquid comprises a softener; as another example, the liquid includes a treatment agent. Thus, the washing water is guided by the water inlet pipe 230, and the washing water is introduced into the washing container together with the liquid for washing the laundry while flowing into the washing container.
