Description

Drum type washing machine with reactive potential energy backflow device
Technical Field
The invention relates to the field of washing machines, in particular to a drum type washing machine with a reactive potential energy backflow device.
Background
The main components of the drum-type washing and dehydrating machine (washing machine) comprise an inner drum, an outer drum, a transmission system, an electrical control system and the like, and each washing cycle usually comprises the working procedures of prewashing, main washing, neutralization, rinsing and the like when the washing machine works; in the washing process, water is required to be added into the inner barrel according to the water level in each procedure, and the clothes fall and rub repeatedly in a certain amount of water to finish the washing, dehydration and other processes. When the inner drum of the washing machine rotates uniformly at a washing rotating speed, clothes can rotate along with the inner drum and the washing-assisting ribs in the inner drum to improve the position after the inner drum rotates, so that the inner drum and the washing-assisting ribs can simultaneously drive the water and the clothes to flow towards the rotating direction of the inner drum, the water flow can form an inclined plane with one side with a raised water level and the other side with a lowered water level in the outer drum under the action of the outer wall of the rotating inner drum and the inner curved surface of the outer drum, and the water in the outer drum continuously flows from a high position to a low position under the action of the height difference and the self weight of the water inclined plane; because the inner cylinder occupies most of the area in the outer cylinder and the main reason of the rising of the water level occurs in the inner cylinder, the water in the inner cylinder can rapidly flow to the outer cylinder; because of the obstruction of clothes, the quantity of water flowing out of the side wall of the inner drum is small, and the main outflow water flow is generated at the gap between the lower front end of the inner drum doorway and the door frame of the front end cover of the outer drum; therefore, because the clothes float in the water, the exposed corners can flow along with the water, the corners can be continuously brought into the gaps by the water, and the corners are pulled back to the inner cylinder by the large-area main body in the inner cylinder along with the rotation of the inner cylinder; in the reciprocating process of entering the gap and pulling in the inner drum, when the length of the clothes entering the gap is large and the thickness of the clothes is large, because the gap between the lower front end of the door opening of the inner drum and the door frame of the front end cover of the outer drum is not uniform, mechanical obstruction can be formed when the clothes enter from the position with the large gap and are pulled out from the position with the small gap in the rotation of the inner drum, the hidden danger that the clothes are crushed or worn is caused, and therefore the main potential risk of clothes damage in washing is realized, wherein the damage rate of the clothes, particularly soft and smooth fabric materials, is higher.
Based on the above, it is particularly necessary to provide a washing machine which can effectively prevent the clothes from entering the gap between the lower front end of the inner drum door and the door frame of the front end cover of the outer drum during washing and reduce the damage probability of the clothes.
Disclosure of Invention
In order to overcome the defect that the clothes to be washed cannot be effectively prevented from entering a gap between the lower front end of the doorway of the inner cylinder and the door frame of the front end cover of the outer cylinder in practical use due to the structure limitation of the existing washing and dehydrating machine, so that the damage probability of the clothes is caused, the invention provides the washing machine, the middle parts of the outer ends of the left side and the right side of the outer cylinder of the washing machine body are respectively provided with a water taking port, two water return pipes are arranged in front of the lower front end of the doorway of the inner cylinder of the washing machine body, when the washing machine works, external power is not needed, the water flow potential energy rising along with the outer wall of the inner cylinder in the washing process can be effectively utilized, no matter the inner cylinder rotates forwards and backwards, higher water flows flow to the gap between the lower front end of the doorway of the inner cylinder of the washing machine body and the door frame of the front end cover of the outer, therefore, the probability that clothes enter a gap between the lower front end of the inner barrel door opening and the outer barrel front end cover door frame is reduced, and the probability that the clothes are crushed or worn is reduced.
