The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. 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 inventive step, are within the scope of the present application.

A door seal 200 of a drum washing machine according to an embodiment of the present application is described below with reference to fig. 1 to 6. The drum washing machine includes an inner tub 400 for containing laundry, an outer tub 300 fitted over an outer side of the inner tub 400, and a front door panel 100 provided at an opening side of the outer tub 300. The front door panel 100 is provided with a door cover, and when the door cover is covered with the front door panel 100, a closed space is formed with the inner cylinder 400.

As shown in fig. 1 and 2, the door frame 200 includes: a first connecting part for connecting the front door panel 100; a transition part connected with one side of the first connection part; and a second connecting part connected to the other side of the transition part departing from the first connecting part, wherein one side of the second connecting part departing from the transition part is used for connecting the inner cylinder 400 and the outer cylinder 300 simultaneously.

For example, the first connection portion, the transition portion, and the second connection portion may be integrally formed by a casting process or an injection molding process. For example, the door seal 200 may be a metal piece and formed by machining through a casting process. For another example, the door seal 200 may be an injection molded piece and injection molded by an injection molding process.

It should be noted that, since the front door panel 100 and the outer tub 300 of the drum washing machine are stationary relative to the drum washing machine, the door seal 200 may be fixedly connected with the front door panel 100 or detachably connected, but for convenience of maintenance, detachable connection, such as snap connection, is preferred. Also, when the drum washing machine washes laundry, the inner tub 400 is not only rotated at all times, but also the inner tub 400 approaches the outer tub 300 under the influence of the laundry or its own weight, but normal operation is not affected. Therefore, when the door seal 200 is connected to the inner cylinder 400, a certain moving space needs to be provided for the inner cylinder 400 at the part of the door seal 200 connected to the inner cylinder 400, so as to prevent the door seal 200 from contacting the inner cylinder 400 to generate friction when the inner cylinder 400 approaches the outer cylinder 300, thereby affecting the normal operation of the drum washing machine.

For example, when the second connecting part wraps the flanging at the front end of the inner cylinder 400 of the drum washing machine, the horizontal distance of the second connecting part wrapping the flanging of the inner cylinder 400 is 13mm, the minimum gap between the second connecting part and the inner cylinder 400 is 1.6mm, the maximum gap is not more than 3.8mm, and the gap between the second connecting part wrapping the inner cylinder 400 and the flanging of the inner cylinder 400 is 2.3 mm. Tests show that the design can prevent objects such as coins, buttons, toothpicks, paper clips and the like from falling between the inner barrel 400 and the outer barrel 300 when the roller washing machine works; secondly, not only the safety of the drum washing machine during operation is ensured, but also the cost is saved under the condition that the normal operation of the drum washing machine is not influenced. In addition, tests show that the wall thickness of the thinnest part of the part, wrapped by the inner cylinder 400, of the second connecting part is 0.6mm under the conditions that the strength of the part, wrapped by the inner cylinder 400, of the second connecting part is not affected and certain cost can be saved.

In the embodiment of the present application, the door seal 200 simultaneously connects the front door panel 100 and the drum washing machine, and also wraps the front flange of the drum washing machine, so as to reduce the gap between the inner drum 400 and the outer drum 300 of the drum washing machine. The clothes are prevented from being pinched and damaged when the drum washing machine works; and can prevent coins, buttons, toothpicks and other small objects from falling between the inner cylinder 400 and the outer cylinder 300 of the drum washing machine, generating abnormal sound, even damaging the wall of the inner cylinder 400 and the wall of the outer cylinder 300, and possibly causing the water discharge valve or the water discharge pump to work abnormally so as to cause the damage of the drum washing machine. Not only improves the user experience, but also effectively prolongs the service life of the drum washing machine.

When putting into drum type washing machine's inner tube 400 to the clothing, closing the door closure, the door closure is at the in-process of closing tightly, can make first section 211 crooked right, first section 211 with the inseparable laminating of door closure that pushes down under the effect of external force under the deformation effect of self together, consequently, under door closure and first section 211 interact, can be so that drum type washing machine's inner tube 400 forms an inclosed space, when the washing clothing, the water in the inner tube 400 can not spill over.

In the present embodiment, the size, shape, and the like of the strain relief groove 213 are not particularly limited. For example, the deformation groove 213 may be a V-shaped groove, a rectangular groove, or the like, as long as the deformation groove 213 can make the first segment 211 be easily bent and deformed.

Illustratively, the first connecting portion may be made of an elastic material, for example, the first connecting portion may be made of rubber.

Illustratively, a protrusion 214 is disposed at an end of the first segment 211 away from the transition portion, and the protrusion 214 is to prevent the first segment 211 from being deformed in a bending manner, so that the first segment 211 is in direct contact with the transition portion, and the contact area between the first segment 211 and the transition portion is increased, thereby increasing the friction force between the first segment 211 and the transition portion, which is not beneficial to the deformation recovery of the first segment 211.

As shown in fig. 6, in an embodiment, a first fastening groove 215 is formed on the second section 212 for fastening the front door panel 100, a notch of the first fastening groove 215 faces the transition portion, and the first fastening groove 215 is inclined with respect to the transition portion.

After the first clamping groove 215 and the transition portion are obliquely arranged, the front door panel 100 and the door seal 200 can be conveniently detached and connected, and convenience is provided for subsequent irregular cleaning or replacement of the door seal 200.

In addition, the shape, size, etc. of the first catching groove 215 need to be selected appropriately according to the thickness and shape of the front door panel 100, and there is no specific requirement here. And as for the depth of the first clamping groove 215, no specific limitation is made in the embodiment of the present application, and it is only necessary to ensure that the first clamping groove 215 can clamp the front door panel 100, and the rollers cannot be separated from each other during washing.

In one example, the first snap groove 215 may also be disposed perpendicular to the transition portion.

As shown in fig. 6, in one embodiment, a side of the second section 212 facing away from the transition portion is provided with a groove 216, and the groove 216 is provided with a fastener for fastening the first snap groove 215 to snap the front door panel 100. Through the effect of fastener, door plant 100 before further fixed first joint groove 215 joint prevents that drum type washing machine from when carrying out washing work, because drum type washing machine's vibration, leads to preceding door plant 100 to break away from first joint groove 215.

In one example, the fastener may be a bead ring comprised of steel wire. The front door panel 100 is fastened in the first catching groove 215 by the steel wire surrounding one or more turns in the groove 216, preventing the front door panel 100 from being separated out of the first catching groove 215.

In one example, the radial center line of the groove 216 may be parallel to the radial center line of the first snap groove 215, so that the fastening effect of the fastener can be enhanced.

In one embodiment, the transition portion is S-shaped in cross-section along the radial direction, as shown in fig. 6. By arranging the transition part in the S-shape, the inner drum 400 can play a role in buffering when the outer drum 300 is close to and rotationally pulled during the operation of the drum-type washing machine. The door seal ring 200 is prevented from being separated from the front door panel 100, the door seal ring 200 and the inner cylinder 400, or the door seal ring 200 and the outer cylinder 300, the door seal ring 200 is difficult to reduce the gap between the inner cylinder 400 and the outer cylinder 300, so that the washed clothes are clamped and damaged, and/or small articles such as coins, buttons, paper clips, toothpicks and the like fall into the gap between the inner cylinder 400 and the outer cylinder 300, which causes bad experience of users, even damages the drum washing machine and shortens the service life of the drum washing machine.

In one example, the transition portion may also be Z-shaped in cross-section along the radial direction.

Illustratively, one end of the transition portion is connected to one side of the first connection section 231, and two ends of the other side of the first connection section 231 extend out of the second connection section 232 and the third connection section 233 respectively in a direction away from the transition portion. Since the second connection section 232 and the third connection section 233 are respectively formed by extending from both ends of the first connection section 231, the second connection section 232 and the third connection section 233 do not cross each other and do not interfere with each other. The inner tub 400 and the outer tub 300 respectively connected by the second connection section 232 and the third connection section 233 do not interfere with each other, thereby affecting the normal operation of the drum washing machine.

As shown in fig. 6, in one embodiment, a second fastening groove 234 is formed by surrounding the second connecting section 232 and a side of the first connecting section 231 away from the transition portion, and the second fastening groove 234 is used for fastening the outer barrel 300.

Illustratively, the second connection segment 232 may be L-shaped; it may also be in combination with the first connection segment 231 to present an S-shape to reduce the material usage of the second connection segment 232.

Further, in order to prevent the outer barrel 300 from being separated from the second clamping groove 234, the end of the second connecting section 232 departing from the first connecting section 231 may be extended inward in the radial direction of the transition portion, so as to increase the contact area between the second connecting section 232 and the outer barrel 300, further increase the friction force between the outer barrel 300 and the second clamping groove 234, and prevent the relative movement between the second connecting section 232 and the outer barrel 300 from causing the outer barrel 300 to be separated from the second clamping groove 234.

As shown in fig. 6, in one embodiment, the third connecting section 233 and the first connecting section 231 are surrounded to form a third engaging groove 235, and the third engaging groove 235 is used for engaging with the outer cylinder 300.

Illustratively, one end of the first connection section 231 extends out of the third connection section 233 away from the transition portion, a third engaging groove 235 is formed in the third connection section 233, and the third engaging groove 235 is located between the first connection section 231 and the third connection section 233. In order to prevent the outer tub 300 from being separated from the third catching groove 235, and because the contact portions of the outer tub 300 and the third connecting section 233 are located in the third catching groove 235. Therefore, the third engaging groove 235 needs to be formed as deep as possible without affecting the strength of the second connecting portion, so as to increase the contact area between the third connecting section 233 and the outer cylinder 300, further increase the friction between the outer cylinder 300 and the third engaging groove 235, and prevent the outer cylinder 300 from being separated from the third engaging groove 235 due to the relative movement between the third connecting section 233 and the outer cylinder 300.

In one example, one end of the first connection section 231 extends out of the third connection section 233 away from the transition portion, a third clamping groove 235 is formed in the third connection section 233, and the third clamping groove 235 is located between the first connection section 231 and the third connection section 233. The third engaging groove 235 is disposed opposite to the second engaging groove 234, and at this time, the first connecting section 231, the second connecting section 232, the third connecting section 233, and the second engaging groove 234 and the third engaging groove 235 enclose a substantially T-shaped engaging groove for engaging with the outer barrel 300. Through the relative second joint groove 234 and the third joint groove 235 of seting up, the urceolus 300 of joint simultaneously can make urceolus 300 be connected more firmly with the second connecting portion.

In one embodiment, as shown in fig. 6, the third connecting section 233 is provided with a receiving groove 236, and the receiving groove 236 is used for receiving the front end flange of the inner cylinder 400.

In one example, the receiving groove 236 is C-shaped with the opening facing to the right. The C-shaped accommodating groove 236 wraps the front section flanging of the inner barrel 400 of the drum washing machine, wherein the horizontal distance of the C-shaped accommodating groove 236 wrapping the flanging of the inner barrel 400 is 13 mm; the minimum clearance between the C-shaped accommodating groove 236 and the inner cylinder 400 is 1.6mm, and the maximum clearance is not more than 3.8 mm; the clearance between the extension of the C-shaped accommodating groove 236 and the flanging is 2.3 mm. Tests show that the design can prevent objects such as coins, buttons, toothpicks, paper clips and the like from falling between the inner barrel 400 and the outer barrel 300 when the roller washing machine works; secondly, not only the safety of the drum washing machine during operation is ensured, but also the cost is saved under the condition that the normal operation of the drum washing machine is not influenced.

In one example, the extension of the C-shaped receiving groove 236 extends downward in the radial direction of the transition portion to form an extension, which is the thinnest portion of the C-shaped receiving groove 236 and has a wall thickness of 0.6 mm.
