The other end of the water inlet pipe is connected with a tap water faucet (not show in Figs). Tap water flows successively through the water inlet pipe, the water inlet, a water inlet path into a washing tub. The water inlet path is provided inside the washing machine and the water inlet path is a water path which the tap water flows through from the water inlet into the washing tub. The water inlet path is a water supply pipe installed in the washing machine or is a water passage in the water inlet valve. A housing 1 of the washing machine of the present disclosure is provided with a filter mounting opening 4, the filter mounting opening 4 is communicated with the water inlet path 3. An inflowing-water filter 5 is detachably mounted in the water inlet path 3 through the filter mounting opening 4 to filter the impurities of the incoming water of the washing machine.

Embodiment 1

[0038] As shown in from FIG. 4 to FIG. 6, a water inlet valve 6 of a washing machine of the present embodiment comprises a valve body 61, a water inlet end 62 and a water outlet end 63. The valve body 61 is provided with a filter mounting end 64. An end opening of the water inlet end 62 is a water inlet 2 of the washing machine. An end opening of the filter mounting end 64 is a filter mounting opening 4 of the washing machine. The inflowing-water 5 filter is detachably mounted inside the valve body 61 through the filter mounting end 64.

[0039] Specifically, the water inlet path 3 is provided inside the valve body 61, two ends of the water inlet path are communicated with a water inlet end 62 and a water outlet end 63. The water inlet path is provided with a plug 65 which is controlled by the electromagnetic components to open and close (the structure is a solenoid valve structure in a conventional washing machine, which is not shown). The filter mounting end 64 is communicated with the water inlet path between the water inlet end 62 and the plug. As the existing washing machine has more and more functions, different procedures require different effects of water, such as spray water, main water, rinsing water, etc. which need different water outlets. Therefore, the inlet valve is a one-way in and multi-way out structure, that is, with several water outlets. But no matter how many water outlets are provided, there is a water outlet which is closest to the water inlet and a plug which controls the water outlet. The inflowing-water filter 5 is provided in the water inlet path between the water inlet 62 and the plug closest to the water inlet (see FIG. 5 and FIG. 6) to prevent the impurities in the incoming water from affecting the service life of the plug.
