[0074] See also Figures 7 to 12 As shown, in some embodiments, a cavity 47 is formed on the inner wall of the fountain plate 4 toward the outer periphery of the inner cylinder 22, and a delivery port is formed at the front opening of the cavity 47. The bottom of the cavity 47 is open, and the delivery port can be connected to the top of the water flow channel 40 through the bottom opening of the cavity 47. Therefore, when the flip cover 5 opens the delivery port, washing powder can be put into the cavity 47 from the delivery port, and then enter the water flow channel 40 through the bottom opening of the cavity 47, and the washing powder is directly delivered into the washing chamber 20 through the bottom of the water flow channel 40.

[0075] See also Fig. 9As shown, in some embodiments, the outer wall of the fountain plate 4 facing the outside of the inner cylinder 22 is convexly provided with a first guide rib 48 and a second guide rib 49. The first guide rib 48 and the second guide rib 49 are arranged at intervals from left to right. The first guide rib 48 is arranged between the delivery port and the first limiting rib 42, the top of the first guide rib 48 extends to the bottom opening of the concave cavity 47 and is connected to one side wall of the delivery port, and the bottom of the first guide rib 48 is connected to the top of the first limiting rib 42. The second guide rib 49 is arranged between the delivery port and the second limiting rib 43, the top of the second guide rib 49 extends to the bottom opening of the concave cavity 47 and is connected to the other opposite side wall of the delivery port, and the bottom of the second guide rib 49 is connected to the top of the second limiting rib 43. Therefore, the first guide rib 48 can connect one side wall of the delivery port and the first limiting rib 42, and the second guide rib 49 can connect the other side wall of the delivery port and the second limiting rib 43, so that the washing powder can smoothly enter the water flow channel 40 from the delivery port.

[0076] In some embodiments, the lateral width of the delivery port is greater than the lateral width of the water flow channel 40, the first guide rib 48 is arranged to extend downwardly and obliquely toward the direction close to the second guide rib 49, and the second guide rib 49 is arranged to extend downwardly and obliquely toward the direction close to the first guide rib 48, so that a funnel-shaped channel is formed between the first guide rib 48 and the second guide rib 49, so that the washing powder can smoothly enter the water flow channel 40 from the delivery port, and be directly delivered into the washing chamber 20 through the bottom of the water flow channel 40.

[0077] It should be noted that, in other embodiments, the lateral width of the injection port may also be equal to or smaller than the lateral width of the water flow channel 40 .

[0078] See also Figures 10 to 12 As shown, in some embodiments, when the flap 5 closes the delivery port, a second fountain port 410 is formed between the side edge of the flap 5 and the peripheral side edge of the delivery port, and the second fountain port 410 is connected to the inside of the concave cavity 47, and is connected to the top of the water flow channel 40 through the bottom opening of the concave cavity 47. When the washing machine is running, the water in the washing cavity 20 can enter the water flow channel 40 from the bottom end of the water flow channel 40 under the action of centrifugation. When the water level in the water flow channel 40 rises to the second fountain port 410, the water in the water flow channel 40 can be sprayed into the washing cavity 20 through the second fountain port 410, forming a waterfall fountain, washing the clothes in the washing cavity 20, and at the same time washing the residual washing powder in the concave cavity 47 and the delivery port, reducing the residual washing powder, and effectively avoiding the problem of washing powder agglomeration in the delivery port, the concave cavity 47 and the water flow channel 40.

[0079] In some embodiments, the second fountain opening 410 is formed between the top edge of the flip cover 5 and the top edge of the delivery port. It should be noted that in other embodiments, the second fountain opening 410 may also be formed between other side edges of the flip cover 5 and the corresponding edges of the delivery port.

[0080] Based on the above technical solution, the embodiment of the utility model has at least the following advantages and positive effects:

[0081] In the pulsator washing machine of the present invention embodiment, the drum assembly 2 includes an outer drum 21 and an inner drum 22, a washing chamber 20 is formed in the inner drum 22, a fountain plate 4 is provided on the peripheral side wall of the inner drum 22, a water flow channel 40 connected to the washing chamber 20 is formed in the fountain plate 4, and a first fountain port 41 and a delivery port located above the first fountain port 41 are arranged on the fountain plate 4, so that the water in the washing chamber 20 can rise along the water flow channel 40 and be re-sprayed into the washing chamber 20 through the first fountain port 41, thereby flushing the clothes in the washing chamber 20; at the same time, the delivery port is connected to the top of the water flow channel 40, and the delivery port is opened and closed by the flap 5. When the flap 5 opens the delivery port, washing powder can be added through the delivery port, and the laundry can be directly delivered into the washing chamber 20 through the delivery port and the water flow channel 40 in sequence. The water flow channel 40 is relatively wide, so that the washing powder can be smoothly put into the washing chamber 20 through the water flow channel 40, and even when the water level is low, there will still be a large flow of water passing through the water flow channel 40, which can flush the washing powder remaining in the water flow channel 40 into the washing chamber 20, effectively preventing the washing powder from being blocked and solving the problem of washing powder easily agglomerating and clogging.
