It should be understood by those skilled in the art that the embodiments of the present invention are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the components in the drawings are illustrated in a certain proportional relationship, the proportional relationship is not constant, and those skilled in the art can make modifications as required to adapt to specific applications, and the modified embodiments will still fall within the scope of the present invention.
It should also be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
As shown in fig. 1 and 2, the drum washing machine of the present invention mainly includes a cabinet 1, an outer tub 2, an inner tub 3, a door 4, a sealing window gasket 5, a drain pump 6, and a drain pipe 7. Wherein the outer cylinder 2 is fixedly disposed inside the cabinet 1, the inner cylinder 3 is rotatably disposed in the outer cylinder 2, and the sealing window gasket 5 is disposed between the cabinet 1 and the outer cylinder 2.

With continuing reference to fig. 1 and 2, the drum washing machine of the present invention further includes a spraying system, which mainly includes a circulation pump 8, a water outlet pipe 9, a control valve 10, eight branch pipes 11 and eight nozzles 12. Wherein the circulation pump 8 is preferably arranged within the tank 1 and fixedly connected to the tank 1. Alternatively, the circulation pump 8 may be fixedly connected to the outer tub 1 as required by those skilled in the art. The water inlet of the circulation pump 8 opens into the interior of the outer tub 2, and preferably the water inlet of the circulation pump 8 is connected with the bottom end of the outer tub 2 through a water inlet pipe (not shown). Or the person skilled in the art can connect the water inlet pipe to any position of the outer cylinder 2, if necessary, while ensuring that the water inlet pipe is located below the liquid level in the outer cylinder 2. The water outlet of the circulating pump 8 is communicated with the water inlet valve port 1011 of the control valve 10 through the water outlet pipe 9. Alternatively, the person skilled in the art may omit the water outlet pipe 9 as needed, so that the water outlet of the circulation pump 8 is directly communicated with the water inlet valve port 1011 of the control valve 10.
As shown in fig. 2 to 4, eight nozzles 12 are provided on the sealing window gasket 5 at equal intervals around the circumferential direction of the outer cylinder 2.
