As shown in fig. 1, the top-loading drum washing machine of the present invention mainly comprises a cabinet (not shown), an outer drum 1 and an inner drum 2 from outside to inside. Wherein, the top of the box body is pivotally provided with an upper cover, the top of the outer cylinder 1 is pivotally provided with an outer cylinder cover 11, and the inner cylinder 2 is pivotally provided with an inner cylinder cover at a position corresponding to the outer cylinder cover 11 in the circumferential direction. When the inner drum cover rotates to the top of the inner drum 2, the upper cover, the outer drum cover 11 and the inner drum cover are aligned, and a user can open the upper cover, the outer drum cover 11 and the inner drum cover in sequence to put clothes into the inner drum 2 or take the clothes out of the inner drum.

It should be noted that, although not shown in the drawings, the upper cover and the outer tub cover 11 of the top-loading drum washing machine of the present invention are separately provided. As an alternative embodiment of the present invention, the upper cover and the outer cylinder cover 11 may be integrally formed as required by those skilled in the art. Since embodiments of this solution are readily available to the skilled person, they will not be described in more detail here.

With continued reference to fig. 1, the outer tub cover 11 of the present invention is further provided with a detergent box 111. Specifically, the detergent box 111 is disposed inside the outer drum cover 11 (bottom side after the outer drum cover 11 is closed), and the detergent box 111 includes a delivery port 1111 and a water outlet 1112. The input port 1111 is disposed at a side of the detergent box 111 close to the free end of the outer tub cover 11, so that a user can add detergent into the detergent box 111 when opening the outer tub cover 11. The water outlet 1113 is provided at the bottom of the detergent box 111 so that the detergent box 111 can be completely discharged when the outer tub cover 11 is closed.

It can be understood by those skilled in the art that the detergent box 111 of the present invention is not limited to the one shown in fig. 1, but may be in any other feasible form, for example, a detergent box having two, four, or five dispensing chambers. In addition, the skilled person can also set the detergent box 111 on the outer tub 1 at any other position except the outer tub cover 11 as required. Alternatively, a person skilled in the art can set the detergent box 111 on the box or the upper cover of the box as needed, as long as the detergent of the detergent box 111 can flow into the inner drum 2 after flowing out from the water outlet 1112.

With continued reference to fig. 1, the inner cylinder cover mainly includes a first inner cylinder cover 21 and a second inner cylinder cover 22. The first inner cylinder cover 21 and the second inner cylinder cover 22 are pivotally provided in the circumferential direction of the inner cylinder 1, respectively, and the first inner cylinder cover 21 and the second inner cylinder cover 22 are provided in a split manner. In the preferred embodiment of the present invention, the first inner cylinder cover 21 and the second inner cylinder cover 22 can be locked to each other when both are closed.

Further, it should be noted that the inner cylinder cover of the present invention is not limited to the first inner cylinder cover 21 and the second inner cylinder cover 22 which are shown in fig. 1 and are divided, and may be any other possible inner cylinder cover. For example, the inner cylinder cover is constituted by only one cover body, and the cover body may be provided on the inner cylinder 2 so as to be pivotable or slidable.

As shown in fig. 1 and 2, in the preferred embodiment of the present invention, the first inner cover 21 is provided with a reservoir 21, a first guide groove 212, a second guide groove 213, and a third guide groove 214. The position of the liquid storage tank 21 can be aligned with the water outlet 1112 of the detergent box 111, so that when the outer cylinder cover 11 is closed, the detergent in the detergent box 111 can directly enter the liquid storage tank 21 after flowing out of the water outlet 1112. Further, the liquid storage tank 21 communicates with the first guide tank 212, the second guide tank 213, and the third guide tank 214, respectively. As shown in fig. 1, the first guide grooves 212, the second guide grooves 213 and the third guide grooves 214 are respectively provided in the axial direction of the inner tub 2 as a whole so that the detergent can uniformly fall into the inner tub 2 through the first guide grooves 212, the second guide grooves 213 and the third guide grooves 214.

In addition, the skilled person can omit the liquid storage tank 21 as required, so that the detergent in the detergent box 111 directly falls into the

diversion trenches

212, 213 and 214. Further, the number of the diversion trenches shown in fig. 1 and 2 can be adjusted by those skilled in the art as needed, for example, it can be adjusted to one, two, four, five, etc. Further, the shape of the

channels

212, 213, 214 shown in fig. 1 and 2 can be adjusted by those skilled in the art according to the requirement, for example, the shape of each of the three channels is made to be linear.

Further, although not shown in the drawings, the bottoms of first guide grooves 212, second guide grooves 213, and third guide grooves 214 are provided with a plurality of through holes. The through-holes are used to allow the detergent in the first guide groove 212, the second guide groove 213, and the third guide groove 214 to enter the inner tub 2. Preferably, the through holes in each of the guide grooves are arranged at equal intervals, and the diameter of the through holes is gradually increased along the direction in which the detergent in each of the guide grooves flows. That is, the diameter of the through hole closer to the reservoir 211 is smaller. The diameter of the through-holes is set so as to prevent a phenomenon that the detergent is not present at the end of the guide grooves (212, 213, and 214) and then accumulates in the inner tub 2, since the detergent is introduced into the inner tub 2 from the through-holes in a large amount just after the detergent is introduced into the guide grooves (212, 213, and 214). When the detergent just enters the guide grooves (212, 213 and 214), the flow rate is large, and a large flow rate can be obtained through the through holes with small diameters. When the detergent flows to the ends of the guide grooves (212, 213, and 214), the flow rate is small, and the flow rate equivalent to the small diameter through-hole can be obtained only through the large diameter through-hole.

In addition, in a preferred embodiment of the present invention, the first inner barrel cover 21 is not penetrated by the sump 211, so that the detergent entering the sump 211 can entirely flow into the guide grooves (212, 213, and 214) and then uniformly fall into the inner barrel 2 through the through holes at the bottom of the guide grooves (212, 213, and 214). Alternatively, a smaller diameter through hole may be provided in the bottom of the reservoir 211 as desired by those skilled in the art.

It should be noted that the detergent flowing out of the detergent box 111 in the embodiment described in this section is a detergent solution diluted with water. The detergent of the present invention includes at least one of a laundry detergent, a softener, a disinfectant, and a detergent.

In summary, the liquid storage tank 21, the first guiding groove 212, the second guiding groove 213 and the third guiding groove 214 of the present invention can make the detergent solution flowing out of the detergent box 111 uniformly fall into the inner tub 2, so as to avoid the detergent solution from intensively entering the inner tub 2 and adhering to the clothes, which causes damage to the clothes and leads to the color fading of the clothes.

So far, the technical solutions of the present invention have been described in connection with 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. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
