It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a drum washing machine, which comprises a door cover, a door seal and a barrel, wherein the door cover is rotatably connected with the barrel, the barrel is provided with an opening, and the door cover can cover the opening. When the door cover is provided with the opening of the barrel part, the door seal is arranged between the door cover and the barrel part to realize the sealing connection of the door cover and the barrel part and prevent the overflow of the washing water.

Referring to fig. 1 to fig. 3, fig. 1 isbase:Sub>A front view ofbase:Sub>A dock seal 100 according to an embodiment of the present disclosure, fig. 2 isbase:Sub>A cross-sectional view of the dock seal 100 shown in fig. 1 alongbase:Sub>A-base:Sub>A, and fig. 3 is an enlarged view ofbase:Sub>A portionbase:Sub>A of the dock seal 100 shown in fig. 2. The door seal 100 comprises a first connecting piece 20, a folded body 10 and a second connecting piece 30 which are connected in sequence, wherein the first connecting piece 20 is used for connecting a door cover, and the second connecting piece 30 is used for connecting a barrel. The pleated body 10 and the second connecting element 30 form a groove structure 206, the pleated body 10 forms a groove bottom and a first groove wall of the groove structure 206, the second connecting element 30 forms a second groove wall of the groove structure 206, and the second groove wall and the first groove wall are oppositely arranged and connected to two opposite ends of the groove bottom. For example, as shown in fig. 2, the pleated body 10 may have an approximately C-shaped structure to ensure a sufficient buffer space when the dock seal 100 is compressed.

Specifically, the corrugated body 10 includes a first corrugated portion 102 and a second corrugated portion 104, one end of the first corrugated portion 102 is connected to the second corrugated portion 104, and the other end of the first corrugated portion 102, which is far away from the second corrugated portion 104, is connected to the first connecting member 20. One end of the second corrugated part 104 is connected with the first corrugated part 102, and the other end of the second corrugated part 104, which is far away from the first corrugated part, is connected with the second connecting piece 30. The first corrugated portion 102 is at least partially in a straight structure, and is partially in an arc structure, and the second corrugated portion 104 is entirely in an arc structure.

Specifically, the first corrugated portion 102 includes a first corrugated section 1022, a second corrugated section 1024, and a third corrugated section 1026 connected in sequence, where the first corrugated section 1022 connects the first connector 20, and the third corrugated section 1026 connects the second corrugated portion 104. The distance from the first corrugated section 1022 to the second connector 30 is smaller than the distance from the third corrugated section 1026 to the second connector 30, and the second corrugated section 1024 extends from the third corrugated section 1026 to the first corrugated section 1022 in a direction inclined toward the second connector 30. The middle of the first folded section 1022, the middle of the second folded section 1024 and the middle of the third folded section 1026 are straight structures, the two ends of the first folded section 1022 and the second folded section 1024 are arc-shaped structures, and when the first folded section 1022 and the second folded section 1024 are sequentially connected, and the second folded section 1024 and the third folded section 1026 are sequentially connected, the connection points are in arc transition.

Illustratively, please continue to refer to fig. 3. In order to improve the connection strength between the first corrugated section 1022 and the first connector 20, the wall thickness of the first corrugated section 1022 is not smaller than the wall thicknesses of the second corrugated section 1024, the third corrugated section 1026 and the second corrugated portion 104. For example, the wall thickness of the first pleat segments 1022 may be 1.0-3.4mm.

The wall thickness of second pleat section 1024, third pleat section 1026, and second pleat section 104 may be 0.7-2.5mm. When the first pleat segment wall thickness is 1.0mm, the wall thickness of the second pleat segment 1024, the third pleat segment 1026, and the second pleat portion 104 may be 0.7-1.0mm; when the first pleat section wall thickness is 3.4mm, the wall thickness of second pleat section 1024, third pleat section 1026, and second pleat portion 104 may be 0.7-2.5mm.

When the inner tub of the drum washing machine is rotated, a large centrifugal force is generated, resulting in a shift of the center of gravity thereof. When more clothes are placed, the inner barrel can drive the outer barrel to generate large-amplitude displacement, and even the whole barrel part is separated from the door seal. In the structure of the door seal 100, when the drum washing machine works, the inner tub rotates to drive the outer tub to vibrate and pull the second wrinkle part 104, and the second wrinkle part 104 drives the first wrinkle section 1022, the second wrinkle section 1024, and the third wrinkle section 1026 to stretch. In one aspect, the first corrugated portion 102, the second corrugated portion 104 and the second connecting member 30 are surrounded to form a groove structure, wherein the second corrugated portion 104 is a circular arc structure, and when the barrel is pulled, the groove structure can more effectively disperse the pulling force and maintain the structural stability. Meanwhile, since the space between the door cover and the tub of the drum washing machine is limited, if the second corrugated portion 104 is directly connected to the first connector 20, the corrugated body 10 may be at risk of self-abrasion. In this groove structure, compared with the direct connection with the first connecting member 20, the connection between the second folding portion 104 and the third folding section 1026 reduces the radius of the circular arc structure of the second folding portion 104, so that the space required for the transverse stretching of the second folding portion 104 is less, and the door cover is not hit by the overlarge stretching amplitude of the second folding portion 104, thereby reducing the self-abrasion risk of the door seal 100. On the other hand, first fold section 1022, second fold section 1024, third fold section 1026 are the multistage fold structure, and the setting of multistage fold structure has increased the tensile length of fold body, and it has bigger elastic strength when the door seal material is the same, is more difficult for breaking. Therefore, when the barrel is rocked, the structure can effectively avoid the large displacement and the eccentric situation of the barrel. The test data shows that when the weight of the load reaches Xg, the existing dock seal is eccentric, and the dock seal 100 increases the threshold to (X + 200) g. In addition, because of the stability of the pleated structure, the dock seal 100 is less susceptible to damage and less expensive to maintain than prior dock seals.

Illustratively, please continue to refer to fig. 3. The first connecting member 20 includes a smooth portion 201, a first connecting portion 202, and a second connecting portion 204, one end of the smooth portion 201 is connected to the first corrugated section 1022, and the other end of the smooth portion 201 is connected to the first connecting portion 202 and the second connecting portion 204. The door cover of the drum washing machine includes a door glass and a door ring, the door glass is mounted on the door seal, and the first connection portion 202 protrudes in a direction away from the second corrugated portion 104 and abuts against the door glass. When being squeezed by the door glass, the first connection portion 202 can deform backward to fit the shape of the door glass, so as to improve the sealing performance of the door seal 100 and the door glass, and prevent the washing water from flowing out of the door glass when the drum washing machine rotates. The second connecting portion 204 protrudes toward the second corrugated portion 104 for being engaged with the door ring flange. The second connecting portion 204 includes a first bending structure 2041, the first bending structure 2041 includes a first bending section and a second bending section, and the first bending section is connected to the smooth portion 201 and protrudes in a direction away from the second connecting member 30. The second bending section is connected to one end of the first bending section far away from the first connecting portion 202 and protrudes toward the smooth portion 201, and the first bending section and the second bending section are surrounded to form a first clamping groove 2042.

Specifically, the second connecting portion 204 further includes a limiting structure 2044 connected to the first bending structure 2041, and the limiting structure 2044 is connected to one end of the second bending section, which is far away from the first bending section, and protrudes toward the second folding portion 104. The door ring flanging is clamped in the first clamping groove 2042 and is abutted to the limiting structure 2044. This structure maintains the second connection portion 204 and the door ring relatively fixed during the operation of the drum washing machine, preventing the door seal 100 from being separated from the door ring.

Illustratively, please continue to refer to fig. 3. The second connector 30 includes a side wall 301, a third connecting portion 302, and a fourth connecting portion 304, wherein one end of the side wall 301 is connected to the second folded portion 104 and the fourth connecting portion 304, the second folded portion 104 and the fourth connecting portion 304 are connected to two opposite sides of the side wall 301, the other end of the side wall 301 is connected to the third connecting portion 302, the third connecting portion 302 and the fourth connecting portion 304 protrude toward the same side of the side wall 301, and the side wall 301, the third connecting portion 302, and the fourth connecting portion 304 surround to form a second clamping groove 3032. The fourth connecting portion 304 includes a bottom wall 3041 and a second bending structure 3042, one end of the bottom wall 3041 is connected to the sidewall 301, and the other end is connected to the second bending structure 3042, and the second bending structure 3042 may be an approximately arch structure. One end of the third connecting portion 302 is connected to the sidewall 301, and protrudes toward one side of the fourth connecting portion 304 along the sidewall, and the other end of the third connecting portion 302 bends toward a direction away from the sidewall 301. The barrel part of the drum washing machine comprises an outer barrel and an inner barrel, the inner barrel is rotatably arranged in the outer barrel, the outer barrel is provided with a flanging structure to be connected with a second connecting groove 3032 in a connecting mode, and the barrel part is prevented from being separated from a door seal 100.

Specifically, the second bending structure 3042 is provided with an anti-slip rib 3034 towards one side of the third connecting portion 302, and the anti-slip rib 3034 may be an anti-slip structure, such as an anti-slip rib, and when the outer barrel flange is clamped in the second clamping groove 3032 and abutted against the fourth connecting portion 304, the anti-slip rib 3034 may increase the friction force between the outer barrel flange and the fourth connecting portion 304, so that the outer barrel and the door seal 100 are clamped more firmly.

For example, referring to fig. 4, fig. 4 is a schematic structural diagram of the dock seal 100 shown in fig. 1. The corrugated body 10 is provided with a plurality of ribs 40 on one side facing the first connector 20, the ribs 40 are adapted to the shape of the corrugated body 10, and the ribs 40 extend from the first corrugated portion 102 to the second corrugated portion 104. The reinforcing rib 40 includes a straight section and an arc section connected to each other, the straight section abuts against the first corrugated portion 102, and the arc section abuts against the second corrugated portion 104. The reinforcing ribs 40 prevent the pleated body 10 from being cracked due to excessive deformation when the door seal 100 is pulled by the tub. The spacing between adjacent ribs 40 can be set according to practical application, for example, the ribs 40 on the upper portion of the door seal 100 are distributed at a wider interval, and the ribs 40 on the lower portion of the door seal 100 are distributed at a narrower interval. The reinforcing ribs 40 are provided to provide a certain supporting force for the pleated body 10 of the door seal 100, so as to increase the overall strength of the door seal 100.

For example, referring to fig. 5, fig. 5 is an enlarged schematic view of a portion B of the dock seal shown in fig. 4. The dock seal 100 includes a spray nozzle 60, the spray nozzle 60 being disposed in the first connector 20. During the operation of the drum washing machine, dirt may remain on the door glass, and the door glass is too cumbersome to detach and wash. The spraying nozzle 60 can be used for feeding water to spray the door glass, so that the door glass can be cleaned more conveniently. In practical applications, the number of the spray nozzles 60 may be one or more. The door seal 100 is further provided with a circulation pump hole 50, and when the washing operation of the drum washing machine is performed for a certain length of time, the circulation pump hole 50 can supply water to the door seal 100. So that the washing powder which is not dissolved in the inner tub or the door seal 100 is fully dissolved. For example, after the drum washing machine finishes one-time cleaning of the clothes, the water outlet hole at the bottom of the outer cylinder is opened and the washing water is pumped to the circulating pipe, the washing water flows into the circulating pump (not shown) through the circulating pipe and then flows back to the circulating pump hole 50, the water is fed into the door seal 100 through the circulating pump hole 50, and the washing water enters the inner tub of the drum washing machine to dissolve the residual washing powder. Through water circulation, the circulation pump hole 50 can not only intake water to clean the door seal 100, but also perform secondary cleaning on the clothes in the inner barrel, so as to reduce the water consumption of the drum washing machine. It is understood that the circulation pump hole 50 may be provided at other locations of the dock seal 100 as long as water can be introduced into the dock seal 100.

For example, referring to fig. 6, fig. 6 is an enlarged schematic view of a door seal portion C shown in fig. 4. The door seal 100 further comprises a water leakage rib 70, the water leakage rib 70 is arranged around the door seal 100, the water leakage rib 70 is provided with a water leakage hole 701, and the water leakage hole 701 is used for guiding residual sewage in the door seal 100 so as to prevent the door seal 100 from being dirty and mildewed.
