The drum washing machine according to the present invention further includes a spray system that mainly includes a circulation pump 8, a water outlet pipe 9, and an annular concave tank 22 installed at the tip 21 of the outer cylinder. Among them, the window packing 5 has a shielding part 51, and the shielding part 51 and the annular groove 22 form an annular water supply 10 (that is, the shielding part 51 covers the opening of the annular groove 22). (A closed annular aqueduct 10 is formed.) In addition, the shielding portion 51 is provided with an injection port 511. Circulation pump 8 is preferably installed within housing 1 and fixedly connected to housing 1 . Alternatively, those skilled in the art can also fixedly connect the circulation pump 8 to the outer cylinder 1, if necessary. The water supply port of the circulation pump 8 communicates with the inside of the outer cylinder 2, and is preferably connected to the bottom end of the outer cylinder 2 via a water supply pipe. Alternatively, a person skilled in the art can also connect the water supply pipe to any position of the sheath 2, if desired, provided that it is ensured that this water supply pipe is below the liquid level within the sheath 2. A water outlet of the circulation pump 8 is communicated with an annular water supply 10 via a water outlet pipe 9. When the spray system according to the present invention is in operation, as shown by the arrow in FIG. is injected into the inner cylinder 3.

例として、本発明の環状凹漕２２と出水管９とは、接続構造（例えば、接続ホース、接続硬管など）を介して連通されてもよく、直接連通されてもよく（すなわち、接続構造を使用せずに、出水管９を直接環状凹漕２２に連通させる）、環状凹漕２２と出水管９とは、一体に成形されてもよい。当業者は、実際の設計の必要に応じて適当な接続方式を柔軟に選択でき、循環ポンプ８が出水管９を介して洗浄水を環状凹漕２２内にポンプ輸送できればよい。 As an example, the annular concave tank 22 and the water outlet pipe 9 of the present invention may be communicated via a connection structure (for example, a connection hose, a connection hard pipe, etc.) or may be directly communicated (i.e., a connection structure (The water outlet pipe 9 is directly communicated with the annular concave tank 22 without using the annular concave tank 22.) Alternatively, the annular concave tank 22 and the water outlet pipe 9 may be integrally formed. Those skilled in the art can flexibly choose a suitable connection system according to the actual design needs, as long as the circulation pump 8 can pump the wash water into the annular concave tank 22 via the water outlet pipe 9.

例として、噴射口５１１は、環状水道１０に入られる洗浄水を斜めに内筒３に噴射するためのガイド構造（例えば、噴射口５１１を斜面状に設置する）を有する。加えて、噴射口５１１は、さらに環状水道１０に入られる洗浄水を均一した環状水カーテンに形成した後に内筒３に噴射するための噴射部材を有してもよい。この噴射部材は、環状水道１０に入られる洗浄水が均一した環状水カーテンに形成された後に内筒３に噴射されることを満足するために、噴射口５１１の形状や大きさに従って合理的に設計できることは、当業者には容易に理解される。 For example, the injection port 511 has a guide structure (for example, the injection port 511 is installed in an inclined shape) for injecting the cleaning water entering the annular water supply 10 obliquely into the inner cylinder 3. In addition, the injection port 511 may further include an injection member for forming the cleaning water entering the annular water supply 10 into a uniform annular water curtain and then injecting it into the inner cylinder 3. This injection member is arranged in a rational manner according to the shape and size of the injection port 511 in order to ensure that the cleaning water entering the annular water supply 10 is formed into a uniform annular water curtain and then injected into the inner cylinder 3. Those skilled in the art will readily understand that it can be designed.

The shutoff valve will now open. As example 2, the drain pump 6 is omitted, and one three-way valve is provided at the water outlet of the circulation pump 8 so that the water outlet of the circulation pump 8 is selectively communicated with the water outlet pipe 9 or the drain pipe 7 by the three-way valve.
