Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically, it relates to a washing machine window gasket. Background Technology

[0002] Existing drum washing machines consist of an outer casing containing an outer drum and an inner drum. The inner drum, used for washing, spin-drying, and drying, is rotatably mounted inside the outer drum. The outer casing includes a front panel with a clothes inlet for loading and unloading clothes into or from the inner drum. A gasket is placed between the front panel and the outer drum to ensure a sealed and unobstructed connection. However, existing washing machines have a gap between the inner and outer drums. During operation, foreign objects such as coins, pins, and buttons can easily fall into this gap, causing noise or drainage blockages, resulting in a poor user experience. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a washing machine window gasket. By providing an annular blocking part at one end of the annular mounting part, the annular blocking part is formed by extending from one end of the annular mounting part toward the inner drum. Furthermore, the extended end of the annular blocking part extends to a place that is in contact with or close to the outer wall of the inner drum at the periphery of the inner drum opening, thereby achieving the purpose of blocking the gap between the inner drum and the outer drum and preventing foreign objects from entering the gap between the inner drum and the outer drum.

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0005] The present invention provides a washing machine window gasket. The washing machine includes an outer drum and an inner drum disposed inside the outer drum. The window gasket includes an annular mounting part that is fitted to the opening of the outer drum. One end of the annular mounting part is provided with an annular blocking part that extends toward the inner drum. The extended end of the annular blocking part extends to a place that is in contact with or close to the outer wall of the inner drum surrounding the opening of the inner drum.

[0006] Furthermore, the front end wall of the inner cylinder is a groove-shaped structure with the opening facing backward, the inner cylinder opening is located on the bottom wall of the groove, and the extended end of the annular blocking part is connected to or close to the corner between the groove peripheral wall and the bottom wall of the front end wall.

[0007] Furthermore, the bottom wall of the front end wall is a radially extending straight wall, and the end of the bottom wall of the front end wall is bent outward to form a peripheral wall. The peripheral wall of the front end wall and the bottom wall of the groove are connected at the corner by an annular connecting wall protruding outward. The extended end of the annular blocking part is connected to or close to the annular connecting wall.

[0008] Furthermore, the annular mounting part is coaxially arranged with the annular connecting wall, the radial dimension of the inner circumference of the annular connecting wall is smaller than the radial dimension of the inner circumference of the annular mounting part, and one end of the annular mounting part extends obliquely towards the inner circumference of the annular connecting wall to form an annular blocking part.

[0009] Furthermore, the annular blocking part is straight along its own extension direction, and the inner circumference of the annular blocking part forms a guide surface that guides the washing water on the window gasket to the outer cylinder.

[0010] Furthermore, the inner circumference of the annular mounting part has multiple steps distributed along the axial direction of the annular mounting part, and the multiple steps gradually protrude from one end of the annular mounting part where the annular blocking part is located to the other end of the annular mounting part.

[0011] Furthermore, the radial dimension of the extended end of the annular stop is smaller than the radial dimension of the step with the smallest radial dimension.

[0012] Furthermore, the annular blocking part is provided with several return holes to return the washing water on the guide surface to the outer cylinder.

[0013] Furthermore, the outer peripheral wall of the annular mounting part is provided with a protrusion, and the protrusion is provided with an insertion groove with an opening opposite to the outer peripheral wall of the annular mounting part. The inner periphery of the outer cylinder opening is provided with an insertion protrusion, which is inserted into the insertion groove.

[0014] Furthermore, the washing machine also includes a front panel with a clothes inlet. The other end of the annular mounting part, which is opposite to the annular blocking part, bends and extends to the outer perimeter of the clothes inlet to form an annular blocking part.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0016] 1. By setting an annular blocking part at one end of the annular mounting part, the annular blocking part bends and extends from the annular mounting part towards the clothing inlet to the outer perimeter of the clothing inlet, thus blocking the gap between the front panel and the outer cylinder while avoiding the connection between the window gasket and the front panel, thereby improving the service life of the window gasket.

[0017] 2. By providing an annular blocking part at one end of the annular mounting part, the annular blocking part extends from one end of the annular mounting part toward the inner cylinder, and the extended end of the annular blocking part extends to a place that is in contact with or close to the outer wall of the inner cylinder at the outer periphery of the inner cylinder opening, thereby blocking the gap between the inner cylinder and the outer cylinder and preventing foreign objects from entering the gap between the inner cylinder and the outer cylinder.

[0018] 3. The window gasket and the outer cylinder can be detached by inserting the protrusion into the slot, which facilitates the removal and installation of the window gasket.

[0032] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] like Figure 1-4 As shown, the present invention provides a washing machine window gasket. The washing machine includes an outer drum 4 and a front panel 5. The front panel 5 is provided with a clothes loading port 51. The window gasket 1 includes an annular mounting part 11 that is fitted to the outer drum opening 41. One end of the annular mounting part 11 bends and extends towards the clothes loading port 51 to form an annular blocking part 12 around the clothes loading port 51.

[0034] In an embodiment of the present invention, an annular blocking part 12 is provided at one end of the annular mounting part 11. The annular blocking part 12 is formed by bending and extending from the annular mounting part 11 toward the clothing inlet 51 to the periphery of the clothing inlet 51. This achieves the blocking of the gap between the front panel 5 and the outer cylinder 4, while avoiding the connection between the window gasket 1 and the front panel 5, thereby improving the service life of the window gasket 1.

[0035] The washing machine window gasket 1 can be used in a drum washing machine. The drum washing machine includes a shell, an outer drum 4 located inside the shell, and an inner drum 6 located inside the outer drum 4. The inner drum 6 is used to hold clothes, and the outer drum 4 is used to hold washing water. A front panel 5 is provided on the front side of the shell, and a clothes loading port 51 is provided on the front panel 5 for loading clothes into the inner drum 6 through the clothes loading port 51, the outer drum opening 41, and the inner drum opening 611.

[0036] The annular shielding part 12, the annular mounting part 11, the inner cylinder 6, the outer cylinder 4 and the front panel 5 are coaxially arranged.

[0037] like Figure 4 and Figure 7 As shown, in an embodiment of the present invention, the annular blocking portion 12 includes a first blocking portion 121 and a second blocking portion 122. One end of the annular mounting portion 11 extends outward along the axial direction of the outer cylinder opening 41 to the inner periphery of the clothing inlet 51 to form the first blocking portion 121. The extended end 1211 of the first blocking portion 121 passes through the clothing inlet 51 and bends and extends outward to the periphery of the clothing inlet 51 to form the second blocking portion 122, at least the outer periphery of which overlaps with the front panel 5 portion of the periphery of the clothing inlet 51.

[0038] In an embodiment of the present invention, the first blocking portion 121 is formed by one end of the annular mounting portion 11 extending outward along the axial direction of the outer drum opening 41 to the inner circumference of the clothes inlet 51. The first blocking portion 121 extends to the inner circumference of the clothes inlet 51, thereby blocking the gap between the front panel 5 and the outer drum 4 and preventing foreign objects from falling into the gap between the outer drum 4 and the outer shell. For example, during the operation of the washing machine, foreign objects such as coins, pins, and buttons are likely to fall into the gap between the outer drum 4 and the outer shell.

[0039] The extended end of the first shielding part protrudes from the clothing inlet 51 and bends outward to form a second shielding part 122 whose outer periphery overlaps with the front panel 5 of the outer periphery of the clothing inlet 51. After the second shielding part 122 protrudes from the clothing inlet 51, it overlaps with part of the front panel 5, so that the second shielding part 122 can block the gap between the clothing inlet 51 and the first shielding part 121, preventing foreign objects from falling into the gap between the outer shell and the outer tube 4 through the gap between the first shielding part 121 and the clothing inlet 51 and the gap between the outer tube 4 and the front panel 5 in sequence.

[0040] like Figure 4As shown, further, the radial dimension of the first blocking portion 121 gradually decreases from one end of the annular mounting portion 11 along its own extending direction, and the radial dimension of the extended end of the first blocking portion 121 is smaller than the radial dimension of the inner circumference of the clothing inlet 51 directly opposite the extended end of the first blocking portion 121; the radial dimension of the second blocking portion 122 gradually increases from the extended end 1211 of the first blocking portion 121 along its own extending direction; the first blocking portion 121 and the second blocking portion 122 are arranged in this way to achieve a relatively small gap between the extended end of the second blocking portion 122 and the front panel 5. Being closer to the front panel 5 reduces the likelihood of foreign objects falling sequentially from the gap between the extension end of the second shielding portion 122 and the front panel 5, the gap between the first shielding portion 121 and the clothing inlet 51, and the gap between the outer tube 4 and the front panel 5 into the gap between the outer tube 4 and the outer shell. Furthermore, the first shielding portion 121 and the second shielding portion 122 are configured such that the first shielding portion 121 can block foreign objects sliding down from the second shielding portion 122, and there is no connection between the first shielding portion 121 and the second shielding portion 122 and the front panel 5, thus avoiding the existence of connection stress.

[0041] like Figure 4 As shown, in an embodiment of the present invention, the front panel 5 portion surrounding the clothing inlet 51 is recessed into the outer cylinder 4 to form a first recessed portion 52, and the second blocking portion 122 has a second recessed portion 1221 that is recessed opposite to the first recessed portion 52. The first recessed portion 52 and the second recessed portion 1221 overlap to form a buffer space 2.

[0042] In specific embodiments of the present invention, the front panel 5 is provided with an opening, and the rear side of the front panel 5 is provided with an annular flange at the opening. The annular flange is coaxially arranged with the front panel 5. The inner circumference of the annular flange forms a clothing loading port 51. The radial dimension of the annular flange gradually decreases from front to back, and the annular flange is arc-shaped from front to back. This allows the front panel 5 portion surrounding the clothing loading port 51 to be recessed towards the outer cylinder 4 to form a first recessed portion 52. The second blocking portion 122 has a second recessed portion 1221. The second recessed portion 1221 is recessed in the opposite direction to the first recessed portion 52. The first recessed portion 52 and the second recessed portion 1221 overlap to form a buffer space 2. The buffer space 2 is used to buffer the shaking window pad 1 and prevent the window pad 1 from hitting the front panel 5.

[0043] The second recess 1221 is recessed in the opposite direction to the first recess 52, making the buffer space 2 a buffer space with smaller openings at both ends and a larger central space. This makes it less likely for foreign objects entering the buffer space 2 from the gap between the end of the second blocking part 122 and the front panel 5, that is, the opening of the buffer space 2, to fall from the buffer space 2 into the gap between the outer cylinder 4 and the front panel 5. Since the edge of the front panel 5 at the clothing inlet 51 is relatively sharp, and the edge of the front panel 5 at the clothing inlet 51 is in the larger central space of the buffer space 2, the central space of the buffer space 2 is larger, which can prevent the window pad 1 from hitting the edge of the front panel 5 of the clothing inlet 51.

[0044] like Figure 4 and Figure 7 As shown, the extension end of the second blocking portion 122 bends into the first recess 52 to form a third blocking portion 123. There is a gap 3 between the third blocking portion 123 and the first recess 52, which further reduces the gap between the extension end of the second blocking portion 122 and the front panel 5, and further effectively blocks foreign objects from entering the buffer space 2.

[0045] Furthermore, the first blocking portion 121, the second blocking portion 122, and the third blocking portion 123 are each arc-shaped in their respective extending directions, and the center of the first blocking portion, the center of the second blocking portion 122, and the center of the third blocking portion 123 are located on the same side of the annular blocking portion 12.

[0046] like Figure 4 As shown, further, the inner circumference of the clothing inlet 51 is bent towards the outer cylinder 4 to form a first flange 53. The first flange 53 is directly opposite the second blocking portion 122. The extended end of the first flange 53 is bent away from the second blocking portion 122 and extends to form a second flange 54 directly opposite the front panel 5. The lowest part of the second flange 54 is directly opposite the extended end 1211 of the first blocking portion 121. The arrangement of the first flange 53 and the second flange 54 can prevent the relatively sharp edge of the front panel 5 at the clothing inlet 51 from facing the window pad 1. The first flange 53 and the second flange 54 can reduce the impact damage to the window pad 1.

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, in an embodiment of the present invention, the washing machine includes an outer drum 4, and the window gasket 1 includes an annular mounting portion 11. The outer periphery of the annular mounting portion 11 is provided with an insertion groove 112, and the inner periphery of the outer drum opening 41 is provided with an insertion protrusion 42. At least a portion of the annular mounting portion 11 is embedded in the outer drum opening 41, and the insertion protrusion 42 is inserted into the insertion groove 112.

[0048] In an embodiment of the present invention, the window gasket 1 and the outer cylinder 4 are detachably installed by inserting the insertion protrusion 42 into the insertion groove 112, which facilitates the disassembly and installation of the window gasket 1.

[0049] like Figure 6 As shown, specifically, the front end wall of the outer cylinder 4 includes a first annular portion 43 and a second annular portion 44 coaxially arranged with the outer cylinder 4. The second annular portion 44 is arranged in front of and behind the first annular portion 43. The inner circumference of the second annular portion 44 forms the outer cylinder opening 41. The inner circumference of the front opening of the second annular portion 44 is provided with an insertion protrusion 42.

[0050] The outer peripheral wall of the annular mounting part 11 is provided with a protrusion 111, and the protrusion 111 is provided with an insertion groove 112 with an opening opposite to the outer peripheral wall of the annular mounting part 11. The inner periphery of the outer cylinder opening 41 is provided with an insertion protrusion 42, which is inserted into the insertion groove 112. By providing the insertion groove 112 on the outer peripheral wall of the annular mounting part 11, the insertion strength between the insertion and the insertion protrusion 42 can be increased.

[0051] like Figure 6 As shown, in an embodiment of the present invention, the insertion groove 112 has a first radial segment 1121 with an opening opposite to the outer periphery of the annular mounting portion 11. The end of the first radial segment 1121 opposite to the opening is bent forward to form a first axial segment 1123. The first radial segment 1121 between the first axial segment 1123 and the opening is bent backward to form a second axial segment 1124.

[0052] In embodiments of the present invention, the insertion groove 112 includes a first radial section 1121, a first axial section 1123, and a second axial section 1124. The insertion protrusion 42 includes a first radial protrusion that engages with the first radial section 1121, a first axial protrusion that engages with the first axial section 1123, and a second axial protrusion that engages with the second axial section 1124. This achieves insertion engagement between the insertion groove 112 and the insertion protrusion 42 in both the axial and radial directions. The multi-dimensional insertion engagement increases the insertion strength between the insertion groove 112 and the insertion protrusion 42, thereby improving the assembly strength between the outer cylinder opening 41 and the window gasket 1. A first radial protrusion is provided on the inner circumference of the opening at the front end of the second annular portion 44.

[0053] The insertion groove 112 also includes a second radial section 1122, which is formed by radially bending and extending the end of the first axial section 1123. The second radial section 1122 is disposed opposite to the first radial section 1121, and extends to a point not exceeding the opening of the first radial section 1121. The second radial section 1122 further increases the insertion strength between the insertion groove 112 and the insertion protrusion 42 in the radial direction. The end of the front groove wall of the second radial section 1122 is inclined toward the rear groove wall of the second radial section 1122, which facilitates the disassembly and installation between the insertion groove 112 and the insertion protrusion 42 while ensuring the insertion strength between the insertion protrusion 42 and the insertion groove 112.

[0054] like Figure 6 As shown, further, the front groove wall of the first radial section 1121 is higher than the rear groove wall of the first radial section 1121 and abuts against the front end face of the outer cylinder opening 41, so that the front end face of the second annular portion 44 abuts against the front end face of the first radial section 1121, thereby improving the assembly strength between the second annular portion 44 and the window gasket 1 and providing stability of the window gasket 1 on the outer cylinder 4.

[0055] Furthermore, the front groove wall of the first radial section 1121, the rear groove wall of the second radial section 1122, and the groove wall of the second axial section 1124 together form a guide groove 113. The guide groove 113 is annular and can guide the washing water on the window gasket 1 so that the washing water flows into the housing without electrical components.

[0056] Specifically, the insertion protrusion 42 has a first radial protrusion adapted to the first radial section 1121 and a second axial protrusion adapted to the second axial section 1124. An insertion recess 45 with an opening facing the outer cylinder 4 is formed between the second axial protrusion and the inner circumference of the second annular portion 44. The second axial section 1124 has a groove wall opposite to the outer circumference of the annular mounting portion 11. The groove wall of the second axial section 1124 is embedded in the insertion recess 45, which further improves the insertion strength between the insertion protrusion 42 and the insertion groove 112.

[0057] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, in an embodiment of the present invention, the washing machine further includes an inner drum 6. The other end of the annular mounting portion 11, which is opposite to the annular blocking portion 12, is provided with an annular blocking portion 13 extending toward the inner drum 6. The extended end 131 of the annular blocking portion extends to be in contact with or close to the outer wall of the inner drum 6 around the inner drum opening 611.

[0058] In an embodiment of the present invention, an annular blocking portion 13 is provided at one end of the annular mounting portion 11. The annular blocking portion 13 extends from one end of the annular mounting portion 11 toward the inner cylinder 6. The extended end 131 of the annular blocking portion extends to a point where it is in contact with or close to the outer wall of the inner cylinder 6 around the inner cylinder opening 611, thereby blocking the gap between the inner cylinder 6 and the outer cylinder 4 and preventing foreign objects from entering the gap between the inner cylinder 6 and the outer cylinder 4.

[0059] like Figure 5 As shown, in an embodiment of the present invention, the front end wall of the inner cylinder 6 is a groove-shaped structure with the opening facing backward. The inner cylinder opening 611 is provided on the bottom wall 612 of the groove. The extended end 131 of the annular blocking part is connected to or close to the corner between the groove peripheral wall 613 and the groove bottom wall 612 of the front end wall.

[0060] In an embodiment of the present invention, the inner cylinder 6 includes a cylinder body with openings at both ends and an inner cylinder flange 61 with an opening at one end of the capping cylinder body. The inner cylinder flange 61 has a groove-shaped structure with the opening facing backward. The inner cylinder opening 611 is located in the middle of the bottom wall 612 of the groove. The bottom wall 612 of the groove and the peripheral wall 613 of the groove are arranged one after the other and a corner is formed between them. The extension end 131 of the annular blocking part is connected to or close to the corner, so that the annular blocking part 13 blocks the gap between the inner cylinder 6 and the outer cylinder 4.

[0061] Specifically, the bottom wall 612 of the front wall is a straight wall extending radially, and the end of the bottom wall 612 of the front wall is bent outward to form a peripheral wall 613. The peripheral wall 613 of the front wall and the bottom wall 612 are connected at the corner by an annular connecting wall 614 protruding outward. The extended end 131 of the annular blocking part is connected to or close to the annular connecting wall 614.

[0062] Furthermore, the annular mounting portion 11 is coaxially arranged with the annular connecting wall 614. The radial dimension of the inner circumference of the annular connecting wall 614 is smaller than the radial dimension of the inner circumference of the annular mounting portion 11. One end of the annular mounting portion 11 extends obliquely towards the inner circumference of the annular connecting wall 614 to form an annular blocking portion 13, so that the size of the annular blocking portion 13 gradually decreases from front to back.

[0063] like Figure 5 As shown, specifically, the annular blocking part 13 is straight along its own extension direction, and the inner circumference of the annular blocking part 13 is a smooth surface. The inner circumference of the annular blocking part 13 forms a guide surface 132 that guides the washing water on the window gasket 1 to the outer cylinder 4, so as to avoid wasting the washing water. The annular blocking part 13 is provided with a plurality of return holes that return the washing water on the guide surface 132 to the outer cylinder 4. The plurality of return holes are arranged circumferentially along the annular blocking part 13. Further, the plurality of return holes are provided at the lower part of the annular blocking part 13. The return holes are not shown in the figure.

[0064] like Figure 5As shown, the inner circumference of the annular mounting portion 11 further has multiple steps distributed along the axial direction of the annular mounting portion 11. The multiple steps gradually protrude from one end of the annular mounting portion 11 where the annular blocking portion 13 is located to the other end of the annular mounting portion 11. Specifically, the inner circumference of the annular mounting portion 11 has a first step 114 and a second step 115. The second step 115 and the first step 114 gradually protrude from one end of the annular mounting portion 11 where the annular blocking portion 13 is located to the other end of the annular mounting portion 11. The second step 115 is higher than the first step 114, so that the washing water can flow quickly from the first step 114 to the second step 115, and thus flow to the annular blocking portion 13.

[0065] The radial dimension of the annular blocking part 13 gradually increases from front to back. The annular blocking part can block the washing water flowing from the first step 114 and the second step 115, so that the washing water flows back from the return hole into the outer cylinder 4. The radial dimension of the extended end of the annular blocking part 13 is smaller than the radial dimension of the step with the smallest radial dimension, so that the annular blocking part 13 can block the washing water flowing from the first step 114 and the second step 115 to the greatest extent.

[0066] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
