Embodiment 1

[0061] Such as Figure 1 to Figure 7 As shown, this embodiment introduces a drainage structure of a top-loading drum washing machine. The washing machine includes a drum 800 installed in the housing 100 without dehydration holes. The side wall of the drum 200 is provided with a clothes insertion port 3. 200 is provided with a door cover 300 that can be turned over to open and close the clothes input port; the drum 200 is provided with a drain port 45, and the drain port 45 is provided with a valve core 413 corresponding to the closed opening; a drain structure 400 is also installed in the housing 100, After the drum 200 rotates to a fixed position, the valve core 413 is pushed away to open the drain port 45 .

[0062] By arranging the above-mentioned structure on the drum, after the drum is rotated to a fixed position, the valve core provided at the drain outlet is correspondingly pushed open by the action of the drainage structure, so that the drain outlet of the non-porous d...

Embodiment 2

[0076] Based on the first embodiment above, this embodiment also has the following distinguishing technical features: Figure 1 to Figure 4 As shown, in order to allow the drum to rotate to a fixed position accurately, a positioning structure 500 is also provided on the drum washing machine to limit the rotation of the drum 200 to a fixed position, especially to keep the drum 200 to stop after rotating to a fixed position.

[0077] In this embodiment, the outer circumference of the drum 200 is provided with a positioning groove 55 sunken into the cylinder and a positioning rod 54 that can move telescopically along the radial direction of the drum 200. The positioning rod 54 and the positioning groove 55 are arranged in the same rotating section of the drum 200 to The telescopic end of the positioning rod 54 can extend into the positioning groove 55 correspondingly. Preferably, when the positioning rod 54 is inserted into the positioning slot 55 , the drum 200 rotates to a fixe...

Embodiment 3

[0089] Such as Figure 8 to Figure 10 As shown, this embodiment introduces a water inlet structure 900 of a top-loading drum washing machine. The washing machine includes a drum 200 installed in the housing 100 without dehydration holes, and the side wall of the drum 200 is provided with a clothes insertion port 3 The drum 200 is provided with a door cover 300 that can be turned over to open and close the clothes inlet; the two ends of the drum 200 are sealed, and the center of the sealed end 2 is connected to the housing 100 through the rotating shaft 11 so that it can rotate relatively. At least one end of the rotating shaft 11 is formed by The hollow sleeve is formed, and the hollow part forms the flow channel 90 and communicates with the water inlet pipe of the washing machine.

[0090] By arranging the above-mentioned water inlet structure at the central rotating shaft of the drum, the use function of the top-loading washing machine to feed water into the non-porous drum ...

Abstract

The invention discloses a water inlet end cover applied to a holeless drum. The water inlet end cover is mounted in a bowl-shaped upside-down mode on the inner wall of the drum; a water inlet cavity is surrounded by the water inlet end cover and the drum wall together; and the water inlet end cover is provided with at least one hollow-out part so as to communicate the water inlet cavity with the inside of the drum. The invention further discloses a drum washing machine, wherein a drum comprises a cylindrical side wall; both ends of the cylindrical side wall are respectively sealed so as to form a cylindrical sealed container; and the water inlet end cover is arranged at the center of a sealed end of the drum, so that the water inlet cavity is surrounded by the water inlet end cover and theinner wall of the drum together. By arranging the water inlet end cover at the center of the sealed end of the holeless drum, inlet water flow is blocked by the water inlet end cover to generate divergent spurting so as to increase a covering area of the inlet water flow and promote an immersion wetting effect on clothes. Meanwhile, the water inlet cavity surrounded by the water inlet end cover and the inner wall of the drum together is formed inside the drum so as to take a buffer effect on the inlet water flow and promote water inlet smoothness.

Description

technical field [0001] The present invention relates to washing machine equipment in household appliances, in particular to a top-loading drum washing machine, in particular to a drum washing machine whose drum is composed of a non-porous inner cylinder without dehydration holes and whose top is provided with a clothes feeding port ; Especially relates to a water inlet cover applied to a non-porous drum. Background technique [0002] Washing machines can generally be classified into pulsator type, agitator type and drum type washing machines. Generally speaking, washing machines remove stains from laundry through the action of water and detergent. [0003] The pulsator washing machine performs washing operations by rotating a pulsator in the center of the washing tub left and right. The agitator washing machine uses the friction between the water flow and the laundry to perform the washing operation by rotating the rotating blade in the center of the washing tank left and ...
