At present, most of drainage systems of washing machines in the market are directly connected with a washing cylinder and a drainage pump through a drainage pipe, and after a drainage function is started, the drainage pump is started, so that water in the washing cylinder is drained.

However, the above drainage system is prone to the problem of contamination of the laundry caused by reverse running of the contaminated water into the washing tub. For example, after the drain function of the washing machine is activated, the drain pump is activated to drain the water in the washing tub. Because the drain pipe and the washing drum are directly connected, and the drain pipe is usually specially shaped. When the water is drained, the water in the washing drum can be completely drained, but a certain amount of water can be stored in the drain pipe. When the next washing program is carried out, the water inlet can fill the drain pipe, so that the sewage which is not drained completely last time is reversely communicated into the washing drum, and the molded clothes are polluted. For users with sensitive skin, the problem of poor experience of the users using the washing machine is caused.

In order to solve the above problem, embodiments of the present application provide a washing machine, which will be described below with reference to the accompanying drawings.

Wherein, the tub 10 can be understood as a water holding tub of the washing machine 1. It should be noted that the drum type washing machine 1 may include a washing drum, which may also be referred to as an inner drum, and an outer drum 10 which are engaged with each other. The washing tub rotates with respect to the outer tub 10 to clean the laundry. The washing drum and the outer drum 10 may be both cylindrical drums, wherein the washing drum may have a drum bottom. The tub 10 may be cylindrical without a bottom, and the washing tub may be installed concentrically with the tub 10, so that the washing tub may make a non-eccentric motion with respect to the tub 10, and thus vibration caused by eccentricity of the washing tub with the tub 10 may be reduced. The washing tub typically has an array of through-holes arranged in the wall of the tub. It can be understood that, when the washing program of the washing machine 1 is started, the water entering from the water inlet pipe can directly enter the outer drum 10, and the water quantity with a certain height is stored in the outer drum 10, at this time, because the washing drum has the through hole, the rising of the water level in the outer drum 10 can enable the bottom of the washing drum and a part of the space corresponding to the bottom of the washing drum to be contacted with the water flow, and along with the rotation of the washing drum, the clothes in the washing drum can be contacted with the water flow, so that the clothes can be cleaned.

The guide portion 13 is provided at the lowermost end of the body portion 12. A drain port 11 is provided at the lowest position of the guide portion 13, and the drain pipe 20 communicates with the storage space 14 through the drain port 11. It should be noted that the shape of the drain opening 11 may be circular to facilitate design and manufacture. The guide portion 13 may gradually contract from the connection with the body portion 12 to the drain opening 11 in the horizontal direction X. In the vertical direction perpendicular to the horizontal direction X, the height of the guide portion 13 is lower than the height at which the lowest position of the body portion 12 is located, that is, the guide portion 13 may be understood as a funnel shape. For example, the drain port 11 may be provided at the lowest end of the guide portion 13, and the guide portion 13 may have a predetermined inclination angle from the position of the drain port 11 to the body portion 12 so as to guide the water flowing out of the body portion 12 to flow from the guide portion 13 into the drain pipe 20.
