Problems solved by technology

The increase of the structure reduces the reliability of the whole machine operation, which may cause defects such as defective components, improper assembly, aging failure during use, etc.
In addition, the increase of components will increase the cost and the difficulty of assembly. Moreover, in the case of low-frequency vibration in the cylinder, the vibration frequency of the one-way sealing sheet will also be reduced, and the probability of water and foam overflow will also increase.

Embodiment 1

[0041] Such as Figure 2-4 As shown, in this embodiment, the baffle plate 1 of the anti-overflow device of the water injection port of the drum and the water injection end 3 of the water injection hose 4 are integrally formed, and there is no need for assembly before use, and the components are simple and reliable. And good economy.

[0042] The baffle 1 is an arc-shaped plate protruding from the inner wall of the water injection head 3 to match the water injection port. Preferably, the inner surface of the baffle 1 and the inner surface of the water injection head 3 are smooth transition. It can also be a curved plate or an angled prismatic plate that does not match the water injection port. This kind of arc plate or angled prismatic plate can also play the role of baffle, even when the boundary of the baffle exceeds the diameter of the water injection port. The baffle effect is better, but this kind of baffle is not easy to be integrally formed with the water injection end...

Embodiment 2

[0047] Such as Figure 5 As shown, in this embodiment, the anti-overflow device of the water injection port of the drum and the water injection end 3 of the water injection hose 4 are separate structures, and the two are connected by threads.

[0048] The baffle is provided with an integrally formed connecting pipe 7 , which is fixed by screwing the connecting pipe 7 and the water injection head 3 . More preferably, the outer cylinder 5 is sandwiched between the baffle 1 and the water injection head 3 . The baffle 1 is an arc-shaped plate protruding from the inner wall of the connecting pipe 7 and matched with the connecting pipe 7 , and the inner surface of the baffle 1 and the inner surface of the connecting pipe 7 transition smoothly . The setting of the connecting pipe 7 has the following two situations: one end of the connecting pipe 7 is fixed with the water injection end 3 of the water injection hose 4, and the other end of the connecting pipe 7 is fixed with the plugg...

Embodiment 3

[0053] Such as Figure 1 to Figure 5 As shown, in this embodiment, an anti-overflow device for the water injection port of the drum, the anti-overflow device includes a baffle plate 1, and the baffle plate 1 is installed at the water injection port along the outer cylinder 5 to the inner cylinder 6, The water flow is prevented from flowing back into the water injection port with the high-speed operation of the inner cylinder 6 . According to the principle of fluid mechanics, when the fluid passes through the baffle plate 1 , a diversion flow will be generated to bypass the water injection port and slow down in the region of the water injection port to prevent backflow.

[0054] The ratio L / H of the length L of the baffle plate 1 protruding into the outer cylinder and the distance H between the inner and outer cylinders at the water injection port is greater than 0 and less than 1, preferably between 0.3 and 0.85. The maximum linear width W of the baffle 1 is greater than or e...

Abstract

The invention discloses an anti-overflow device at a roller water injection port and a roller washing machine. The anti-overflow device comprises a water flow baffle, the water flow baffle extends along an outer tube to an inner tube and is installed at the water injection port, and water flow is blocked to run back into the water injection port along with the inner tube at a high speed. The anti-overflow device further comprises a blocking rib, and the blocking rib is arranged on the inner side of the water injection port and close to the outer tube. The roller washing machine comprises the anti-overflow device at the roller water injection port. The principle of fluid mechanics is adopted in the anti-overflow device at the roller water injection port, the change of liquid flow in the roller is realized, and the anti-overflow effect is good; the anti-overflow device at the roller water injection port is simple in structure, and has a high reliability; the components are simple, and the economical efficiency is good.

Description

technical field [0001] The invention relates to an anti-overflow device of a water injection port of a drum and a drum washing machine, in particular to an anti-overflow device of a water injection port of a drum and a drum which utilizes the principle of fluid mechanics to prevent water and foam in the washing tub from overflowing through the water injection port washing machine. Background technique [0002] In the washing process of the existing drum washing machine, if a large amount of detergent is used or the clothes are not too dirty, excessive foam will be generated, and the foam filling in the drum will increase the pressure in the drum. In the subsequent washing process, due to the washing drum The rotation of the washing machine will cause more and more foam, and the lack of space in the washing drum will cause the fluid (mainly foam and water containing detergent and dirt) to overflow. The drum washing machine will overflow from the water storage tank, which will...
