Embodiment 1

[0033] Such as Figure 1 to Figure 4 As shown, a drum washing machine described in the embodiment of the present invention includes a casing 1 and an inner cylinder 3 arranged inside the casing 1, and a water inlet structure is provided in the casing 1 to integrate the external water supply system Water is introduced into the washing machine casing 1, and the water inlet structure includes a water inlet valve 51 connected in series in sequence, a flow sensor 52 and a detergent box 53 for holding laundry; A water inlet 31, the water inlet 31 connects the inside and the outside of the inner cylinder 3; a water inlet channel 6 is provided between the water inlet structure and the water inlet 31, and the water inlet channel 6 guides the water flow introduced by the water inlet structure At the spout 60 which has a gap with the water inlet 31 , the water jetted from the spout 60 crosses the gap to be sprayed into the water inlet 31 and transported into the inner cylinder 3 . The d...

Embodiment 2

[0038]The spout 60 described in the embodiment of the present invention is arranged opposite to the water inlet 31. The water inlet 31 and the spout 60 are two opposite tapered openings. The diameter of the end of the spout 60 facing the water inlet 31 is smaller than that of the water inlet channel 6. The diameter not only increases the pressure of the water flow ejected from the spout 60, but also reduces the diameter of the jetted water column; the diameter of the water inlet 31 towards the inner side of the inner cylinder 3 is greater than the diameter towards the side of the spout 60, and the water inlet 31 The water flow at the center flows into the inner cylinder 3 along the conical surface, and when the inner cylinder 3 is rotated and washed, the water in the inner cylinder 3 is reduced to flow out from the water inlet 31; the diameter of the nozzle 60 facing the water inlet 31 is smaller than that of the water inlet 31 The diameter towards the side of the spout 60 make...

Embodiment 3

[0040] See attached Figures 1 to 4 As shown, the water inlet 31 described in the embodiment of the present invention is arranged at the bottom of the inner cylinder 3, at least part of the water inlet channel 6 passes through the bottom wall of the outer cylinder 2 in a direction parallel to the central axis of the inner and outer cylinders 2, and the water inlet flow The spout 60 of the channel 6 faces the direction of the water inlet 31 .

[0041] In the embodiment of the present invention, such as Figure 4 As shown, the distance from the water inlet 31 to the center of the bottom of the inner cylinder 3 is d, d can be determined according to the diameter of the inner cylinder 3, and the diameter of the inner cylinder 3 is D, wherein, 0.033≤d / D<0.9; preferred , 0.07≤d / D<0.4; more preferably, 0.1≤d / D<0.22. This can ensure that the water in the inner cylinder 3 will not leak out from the water inlet 31 during the washing process.

Abstract

The invention discloses a drum washing machine, which comprises a casing; an inner cylinder arranged inside the casing; a water inlet structure arranged on the casing to introduce water flow provided by an external water supply system into the casing of the washing machine; a water inlet arranged On the inner cylinder, it connects the inside and outside of the inner cylinder; the water inlet channel guides the water flow introduced by the water inlet structure to the nozzle with a gap with the water inlet, and the water jetted from the nozzle crosses the gap and is sprayed to the water inlet and transported to the inner in the barrel. The invention solves the problem of dirt accumulation between the outer wall of the inner cylinder and the inner wall of the outer cylinder, and realizes water inflow into the inner cylinder without holes without affecting the rotation of the inner cylinder.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a drum washing machine. Background technique [0002] Existing drum washing machines generally include an inner cylinder and an outer cylinder that fit each other. There are gaps, and dirt will accumulate after the washing machine has been used for a period of time. Since the inner and outer cylinders are set together, it is impossible to directly clean the outer wall of the inner cylinder and the inner wall of the outer cylinder, which will increase the number of bacteria inside the washing machine and affect the health of the user. The user can only remove the inner cylinder. Cleaning of the outer wall of the inner cylinder and the inner wall of the outer cylinder. [0003] In order to solve the above problems, the inner drum of the drum washing machine is designed as a non-porous inner drum, which can not only hold water but also do laundry. causing waste of w...
