Specifically, referring to fig. 2 to 6, the door structure of the embodiment includes a door panel 10 and a detergent dispensing mechanism disposed at the rear side of the door panel 10, the rear side of the door panel 10 has a fixing structure 11 fitted into a fixing groove 200 on a front panel 20 of the washing machine cabinet to fix the door panel 10 on the washing machine cabinet, and the fixing structure 11 is a sliding hook fitted to slide into the sliding groove. The upper half position, the middle position and the lower half position of the rear side of the door body panel 10 are provided with fixing structures 11.

Specifically, referring to fig. 3, the slide hook has a hook body 111 and a bent portion 112, the hook body 111 is disposed at the rear side of the door body panel 10 and extends outward toward a direction away from the rear side of the door body panel 10; the bent portion 112 is formed by bending the front end of the hook body 111 toward the lower end of the door panel 10, and is adapted to slide into the Y-shaped sliding groove.

Referring to fig. 4, the detergent feeding mechanism in this embodiment includes a water inlet cavity 13, a funnel-shaped detergent containing cavity 14, a sphere 15 and a water storage cavity 16, wherein the water inlet cavity 13 is connected to a water inlet end of the washing machine; wherein:

the detergent containing cavity 14 is communicated with the water inlet cavity 13, the detergent containing cavity 14 is provided with an upper cavity 141 and a lower cavity 142, the upper cavity 141 forms the upper end part of the funnel, and the lower cavity 142 forms the lower end part of the funnel; the upper chamber 141 has an overflow opening 1410, the overflow opening 1410 can be disposed on the sidewall of the upper chamber 141 or the upper end of the upper chamber 141 according to the actual overflow requirement, the sidewall of the lower chamber 142 has a water inlet 1420 communicated with the overflow opening 1410, and the lower chamber 142 has a lower water outlet 1421 matched to communicate with the washing tub, the lower water outlet 1421 can be disposed on the sidewall of the lower chamber 142 or the bottom of the lower chamber 142 according to the requirement. Moreover, the upper cavity 141 is also provided with an upper water outlet 1412 for matching and communicating with the washing barrel; the lower opening 1411 of the upper chamber 141 is communicated with the upper opening 1422 of the lower chamber 142, the caliber size of the lower opening 1411 is greater than or equal to the caliber size of the upper opening 1422, and the caliber size of the lower water outlet 1421 of the lower chamber 142 is smaller than the caliber size of the water inlet 1420 of the lower chamber 142. The overflow 1410 of the upper chamber 141 and the water inlet 1420 of the lower chamber 142 are respectively communicated with the water storage chamber 16.

The ball 15 is located between the lower opening 1411 of the upper cavity 141 and the upper opening 1422 of the lower cavity 142; wherein, when the lower cavity 142 is not filled with water, the ball 15 seals the upper opening 1422 of the lower cavity 142; and, the ball 15 is floatingly disposed in the upper chamber 141 when the lower chamber 142 is filled with water. The upper opening 1422 of the lower cavity 142 is provided with a sealing ring 17 that is fitted with the ball 15 to seal the upper opening.

It should be noted that, by making the aperture size of the lower water outlet 1421 of the lower cavity 142 smaller than the aperture size of the water inlet 1420 of the lower cavity 142, it can be ensured that the amount of water flowing into the lower cavity 142 through the water inlet 1420 is larger than the amount of water flowing out of the lower cavity 142 through the lower water outlet 1421, so that there is a continuous accumulated amount of water in the lower cavity 142 until the accumulated amount of water fills the whole lower cavity 142, and then the ball 15 generates a floating effect under the buoyancy of the water filled in the lower cavity 142. After detergent is put into the detergent containing cavity 14, the state of the sphere 15 when the sphere 15 is not floating is shown in fig. 5, the state of the sphere 15 after floating is shown in fig. 6, and the arrow in fig. 5 and 6 indicates the flow direction of fluid (water flow, detergent or mixture of the water flow and the detergent). The effect of stirring the washing liquid can be achieved by the up-and-down floating of the ball 15, so that the washing liquid is fully mixed with the water.

To avoid a large deviation of the ball from floating when the lower chamber is filled with water, in this embodiment, the upper chamber 121 of the detergent-containing chamber 12 has a limit structure 18 therein defining the floating range of the ball 15. Specifically, the limiting structure 18 is an arc section protruding from the inner side of the upper cavity toward the water inlet cavity, and the radius of the arc corresponding to the arc section is larger than that of the sphere 1.

When the door structure 1 of this embodiment needs to be fixed to the washing machine cabinet 2, all the fixing structures 11 on the door structure 1 are slid into the corresponding fixing slots 200 on the washing machine cabinet 2, so that the fixing structures 11 are fixed in the corresponding fixing slots 200. Due to the arrangement, the door body structure 1 does not need to be provided with screw holes, and the door body structure and the washing machine box body do not need to be fixed by screws, so that the door body panel of the door body structure is prevented from influencing the integral appearance of the door body panel due to the arrangement of the screw holes and the screws; in addition, a decorative ring is not required to be additionally arranged on the front panel of the door body structure, so that the production cost is saved.

In addition, in order to enhance the fixing and assembling effect between the door body structure and the washing machine box body, the lower part of the door body structure can be fixed on the washing machine box body by using screws. Therefore, the assembly effect of the door body structure and the washing machine box body is enhanced, and the attractive surface above the front panel of the door body structure cannot be influenced because the screw is positioned below the door body structure.

The embodiment also provides a drum washing machine, which is applied with the door body structure 1.
