In addition, in order to facilitate the opening and closing of the barrel cover 13, an operation part is arranged on the barrel cover 13, and the operation part can be a concave pit formed by sinking downwards, so that a user can grasp the operation part conveniently to open or close the barrel cover 13.

Of course, the washing machine provided by the embodiment of the present invention further includes a control panel and the like disposed on the housing 11, which is not limited herein.

It should be noted that, in the description of the present invention, the terms "upper" and "top" refer to the side away from the ground, and the terms "lower" and "bottom" refer to the side facing the ground; "inner" refers to a side toward the central axis of the washing tub 1, and "outer" refers to a side away from the central axis of the washing tub 1.

To sum up, the washing machine of the utility model comprises a washing tub 1, a filter, a first liquid storage tank 3, a first water pump 4 and a water return pipeline 5; wherein, the filter and the first liquid storage tank 3 are positioned at the bottom of the washing barrel 1, and the filter is positioned between the first liquid storage tank 3 and the washing barrel 1; the filter is respectively communicated with the first liquid storage tank 3 and the washing barrel 1 and is used for filtering the detergent in the liquid in the washing barrel 1, so that the filtered water is stored in the first liquid storage tank 3; the inlet of the first water pump 4 is communicated with the first liquid storage tank 3, the outlet of the first water pump 4 is communicated with the washing tub 1 through the water return pipeline 5, when the washing is needed again, the first water pump 4 pumps the water in the first liquid storage tank 3 into the washing tub 1 through the water return pipeline 5, so that the water is reused for washing, the water resource is saved, and the washing cost of a user is reduced; and the detergent is filtered by the filter, so that the pollution to the environment caused by the detergent discharged along with water flow is avoided.

So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
