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.

[0047] like Figures 1-7As shown, the present invention provides a sealing structure for a washing machine, including an annular mounting part 11 assembled with the drum opening of the washing machine, a front panel 5 of the washing machine disposed on the outside of the drum opening, a dispensing port 2 of the front panel 5 corresponding to the drum opening, and a blocking part 12 provided at one end of the annular mounting part 11; the blocking part 12 protrudes from the drum opening and is disposed at a distance from the dispensing port 2.

[0048] In embodiments of the present invention, by providing a shielding part 12 at one end of the annular mounting part 11, the shielding part 12 can shield the internal components of the washing machine, mainly the plastic outer drum, making the washing machine look more aesthetically pleasing from the outside. The shielding part 12 serves a decorative function. Furthermore, by maintaining a distance between the shielding part 12 and the front panel 5 without connection, it is possible to prevent the connection between the sealing structure and the front panel 5 from cracking and to prevent the shaking sealing structure from impacting the front panel 5, thereby increasing the service life of the sealing structure.

[0049] The sealing structure of this application is a window gasket 1, which includes an annular mounting part 11 that is assembled with the drum opening of a washing machine.

[0050] The washing machine in the sealing structure can be a drum washing machine, which includes a casing, an outer drum 3 disposed within the casing, and an inner drum 4 disposed within the outer drum 3. The inner drum 4 is a non-perforated drum used to hold washing water, and an inner drum door 41 is provided at the inner drum opening 41, which is closed during washing. Alternatively, the outer drum 3 is used to hold washing water. It should be noted that when the inner drum 4 is a non-perforated drum, the outer drum 3 may not be provided outside the inner drum 4; a water collection structure can be directly provided, such as a water collection trough.

[0051] The front panel 5 is provided on the front side of the casing. The front panel 5 is provided with a loading port 2. The user puts clothes into the inner tube 4 through the loading port 2, the outer tube opening 31 and the inner tube opening 41 in sequence.

[0052] In addition, when the inner cylinder 4 is a water-holding cylinder and the outer cylinder 3 is provided on the outside, or when the outer cylinder 3 is a water-holding cylinder and the inner cylinder 4 is provided inside the outer cylinder 3, the shielding part 12 of this application can also block foreign objects that enter from the gap between the front panel 5 and the outer cylinder 3, preventing foreign objects from entering between the casing and the outer cylinder 3.

[0053] The washing machine drum opening in this application is:

[0054] When the washing machine has an outer drum 3 and an inner drum 4, the washing machine drum opening assembled with the annular mounting part 11 is an outer drum opening 31, an inner drum opening 41, or an outer drum opening 31 and an inner drum opening 41. Preferably, the radial dimension of the outer drum opening 31 is smaller than the radial dimension of the loading port 2.

[0055] When the washing machine does not have an outer drum 3, the washing machine drum opening assembled with the annular mounting part 11 is an inner drum opening 41. Preferably, the radial dimension of the inner drum opening 41 is smaller than the radial dimension of the loading port 2.

[0056] The annular mounting part 11 of this application is coaxially arranged with the cylinder opening;

[0057] The shielding part 12 of this application has a certain extension length in the circumferential direction, which can increase the shielding length of the gap between the inlet 2 and the outer drum opening 31, and increase the shielding area of ​​the internal components of the washing machine in the circumferential direction; preferably, the shielding part 12 of this application is annular.

[0058] The dispensing opening 2 of this application is preferably located in the middle of the front panel 5. The dispensing opening 2 is formed by the front panel 5 being recessed towards the tube opening. The dispensing opening 2 gradually narrows from the front panel 5 towards the tube opening, which can guide the clothes to be dispensed towards the tube opening. Preferably, the dispensing opening 2 is annular.

[0059] The shielding part 12 and the auxiliary shielding part 13 described below are spaced apart from the small end of the delivery port 2, which can further prevent the shielding part 12 and the auxiliary shielding part 13 from hitting the front panel 5 during the shaking of the window pad 1.

[0060] Furthermore, the smaller end of the dispensing port 2 is bent outward to form a rolled edge 51, and the shielding part 12 and the auxiliary shielding part 13 described below are provided with a gap from the rolled edge 51; since the edge of the front panel 5 at the dispensing port 2 is relatively sharp, the rolled edge 51 is provided to reduce friction damage to the swaying window pad 1 and clothing.

[0061] In an embodiment of the present invention, the projection of the shielding portion 12 on the front panel 5 at least partially covers the edge of the delivery port 2.

[0062] In the embodiments of the present invention, the above-mentioned arrangement makes the degree to which the shielding part 12 extends to the outer periphery of the drum opening exceed the dispensing opening 2, thereby increasing the shielding area of ​​the shielding part 12, and also being able to shield the internal components of the washing machine when the window pad 1 shakes.

[0063] Furthermore, the extended end of the shielding part 12 is provided with an auxiliary shielding part 13 that bends towards the front panel 5; the setting of the auxiliary shielding part 13 increases the shielding dimension, so that no matter how the window pad 1 shakes, the shielding part 12 and the auxiliary shielding part 13 can shield the internal components of the washing machine, further preventing the internal components of the washing machine from being seen from the outside of the washing machine.

[0064] Specifically, the shielding part 12 is formed by radially extending one end of the annular mounting part 11; the auxiliary shielding part 13 is formed by axially bending and extending the shielding part 12; on the one hand, this makes the window gasket 1 more aesthetically pleasing, and on the other hand, it makes the radial shielding of the shielding part 12 the main shielding. Because it needs to avoid other components, the auxiliary shielding part 13 is not annular, but is intermittently provided on the shielding part 12.

[0065] In a preferred embodiment, the shielding portion 12 extends radially to be substantially flush with the outer drum peripheral wall 31, so that the radial dimension of the shielding portion 12 is large enough to provide sufficient radial shielding, and no matter how the window pad 1 swings, the internal components of the washing machine cannot be observed from the outside of the washing machine.

[0066] The auxiliary shielding part 13 is groove-shaped with the groove opening facing the inlet 2, so that the auxiliary shielding part 13 can guide and collect water.

[0067] Furthermore, the shielding part 12 is provided with a fixing part 121, which is fixedly connected to the drum wall of the washing machine.

[0068] A fixing part 121 is provided at a position of the shielding part 12 beyond the dispensing port 2, and the fixing part 121 is fixedly connected to the drum wall of the washing machine.

[0069] Specifically, when there is no outer cylinder 3, the fixing part 121 is fixedly connected to the inner cylinder front end wall 42 on the outer periphery of the inner cylinder opening 41. When there is an outer cylinder 3, the fixing part 121 is fixedly connected to the outer cylinder front end wall 32 on the outer periphery of the outer cylinder opening 31. The fixing part 121 is a fixing hole 121a that passes through the blocking part 12 from the front panel 5 toward the cylinder opening.

[0070] There are multiple fixing holes 121a, which are distributed circumferentially along the shielding section. The fixing holes 121a are fixedly connected to the outer front wall 32 of the outer drum opening 31 or the inner front wall 42 of the inner drum opening 41 by screws to prevent the window gasket 1 from falling off the outer drum 3 during the operation of the washing machine and improve the stability of the window gasket 1.

[0071] In an embodiment of the present invention, a water collection part 14, which is surrounded by a shielding part 12 and an auxiliary shielding part 13, is provided below the inlet 2;

[0072] The water collection section 14 is provided with a drain outlet 14a;

[0073] In the embodiments of the present invention, the inner cylinder 4 is a non-perforated cylinder, and an outer cylinder 3 is provided outside the inner cylinder 4. When the non-perforated inner cylinder 4 is dehydrated, the washing water from the outer cylinder 3 and the inner cylinder 4 will splash onto the window gasket 1 from the gap between the outer cylinder 3 and the inner cylinder 4, resulting in residual washing water on the window gasket 1. The water collection part 14 can collect the residual water on the window gasket 1 and discharge it through the drain outlet 14a. Specifically, the shielding part 12 and the auxiliary shielding part 13 guide the washing water into the water collection part 14. The water collection part 14 is trough-shaped, and the washing water in the water guide part is discharged through the drain outlet 14a.

[0074] In a preferred embodiment, the drain outlet 14a is connected to the outer drum 3 of the washing machine. The washing water in the water collection section 14 is discharged into the outer drum 3 through the drain outlet 14a and discharged to the outside from the outer drum 3 during the spin-drying process.

[0075] In a preferred embodiment, the drain outlet 14a is located at the junction of the bottommost shielding part 12 and the auxiliary shielding part 13 of the water collection part 14, and faces the front end wall 32 of the outer cylinder.

[0076] On the one hand, the position of the drain outlet 14a is at the bottom of the water collection section 14, which can speed up the washing and discharge while reducing the residual washing water in the water collection section 14; on the other hand, the outer drum 3 and the drain outlet 14a can be connected by a straight pipe, shortening the length of the pipe and reducing the resistance to the discharged washing water.

[0077] Furthermore, the auxiliary shielding part 13 is bent to form a water-blocking part 15 opposite to the shielding part 12, which blocks water from the water collecting part 14.

[0078] In order to prevent the washing water from leaking out from the side of the water collection part 14 opposite to the shielding part 12, and thus prevent the washing water from being discharged normally from the drain outlet 14a, a water blocking part 15 is provided so that the washing water is always inside the water collection part 14.

[0079] The bottom of the water collection section 14 is deeper than the top of the water collection section 14, so that more washing water can be concentrated at the bottom of the water collection section 14 and reach the drain outlet 14a as quickly as possible by its own gravity.

[0080] The auxiliary shielding part 13 is groove-shaped; specifically, the groove wall of the auxiliary shielding part 13 is arc-shaped.

[0081] In an embodiment of the present invention, the annular mounting portion 11 is provided with an insertion groove 112 on its outer periphery, and the outer cylinder opening 31 is provided with an insertion protrusion on its inner periphery. At least a portion of the annular mounting portion 11 is embedded in the outer cylinder opening 31, and the insertion protrusion is inserted into the insertion groove 112.

[0082] In embodiments of the present invention, the window gasket 1 and the outer cylinder 3 are detachably installed by inserting the plug protrusion into the plug groove 112, which can provide pre-installation for the fixed connection between the window gasket 1 and the outer cylinder 3.

[0083] Specifically, the front end wall of the outer cylinder 3 includes a first annular portion and a second annular portion coaxially arranged with the outer cylinder 3. The second annular portion is located in front of the first annular portion, and the inner circumference of the second annular portion forms the outer cylinder opening 31. The inner circumference of the front end opening of the second annular portion is provided with an insertion protrusion.

[0084] 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 insertion protrusion 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 can be increased.

[0085] Furthermore, the insertion groove 112 has 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, and the first radial segment 1121 between the first axial segment 1123 and the opening is bent backward to form a second axial segment 1124.

[0086] The insertion protrusion has a portion that mates with the first radial section 1121, the first axial section, and the second axial section, realizing the insertion engagement between the insertion groove 112 and the insertion protrusion in both the axial and radial directions. The multi-dimensional insertion engagement can increase the insertion strength between the insertion groove 112 and the insertion protrusion, thereby improving the assembly strength between the outer cylinder opening 31 and the window gasket 1; the inner circumference of the front opening of the second annular portion is provided with a first radial protrusion;

[0087] 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 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 while ensuring the insertion strength between the insertion protrusion and the insertion groove 112.

[0088] Furthermore, 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 31, so that the front end face of the second annular portion abuts against the front end face of the first radial section 1121, thereby improving the assembly strength between the second annular portion and the window gasket 1 and providing stability of the window gasket 1 on the outer cylinder 3.

[0089] 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.

[0090] In an embodiment of the present invention, the other end of the annular mounting portion 11 is provided with a water-blocking portion 16 extending into the inner drum 4 of the washing machine;

[0091] A water passage 6 is formed between the front end wall 32 of the outer cylinder and the front end wall 42 of the inner cylinder near the outer cylinder opening 31;

[0092] Water-blocking section 16, shielding section 12, water inlet 6.

[0093] In the embodiments of the present invention, the inner cylinder 4 is a non-perforated inner cylinder 4, and an outer cylinder 3 is provided outside the inner cylinder 4; when the non-perforated inner cylinder 4 is dehydrated, the washing water from the outer cylinder 3 and the inner cylinder 4 will splash onto the window gasket 1 from the gap between the outer cylinder 3 and the inner cylinder 4. In order to reduce the splashing of washing water onto the window gasket 1, a water-blocking part 16 is provided on the annular mounting part 11. The water-blocking part 16 partially blocks the water outlet 6 formed between the front end wall 32 of the outer cylinder and the front end wall 42 of the inner cylinder.

[0094] The reason for partially blocking the water is to prevent the water-blocking part 16 from contacting the front wall 42 of the inner cylinder, and to avoid the window gasket 1 from hitting the front wall 42 of the inner cylinder when it shakes.

[0095] Furthermore, the water-blocking part 16 gradually extends outward at an angle and passes through the water inlet 6 into the space between the front end wall 32 of the outer drum and the front end wall 42 of the inner drum; the inclined water-blocking part 16 can guide the washing water and introduce it into the outer drum 3.

[0096] In an embodiment of the present invention, a blocking portion 17 extending toward the inner cylinder 4 is provided on the inner circumferential side of the water-blocking portion 16;

[0097] The front end wall 42 of the inner cylinder is recessed into the front panel 5 to form a recessed portion 421;

[0098] The inner cylinder opening 41 is located at the bottom 421a of the recess;

[0099] The water-blocking part 16 extends toward the side part 421b of the recess;

[0100] The blocking part 17 extends to the side part 421b of the recess and the corner of the bottom.

[0101] In an embodiment of the present invention, a blocking part 17 is provided at one end of the annular mounting part 11. The blocking part 17 extends from one end of the annular mounting part 11 toward the inner cylinder 4. The extended end of the blocking part 17 extends to a position close to the outer wall of the inner cylinder 4 around the inner cylinder opening 41, preventing foreign objects from entering the outer cylinder 3 through the gap between the inner cylinder 4 and the outer cylinder 3. The foreign objects can be coins, etc. At the same time, the blocking part 17 is provided inside the water-blocking part 16, which can assist the water-blocking part 16 in blocking the washing water. Of course, the water-blocking part 16 can also assist the blocking part 17 in blocking foreign objects.

[0102] The extended end of the blocking part 17 is close to the front wall 42 of the inner cylinder, which can prevent the blocking part 17 from hitting the front wall 42 of the inner cylinder when the window gasket 1 shakes.

[0103] Specifically, a corner is formed between the side portion 421b of the recess and the bottom portion 421a of the recess, and the extended end of the blocking portion 17 is close to the corner; further, the blocking portion 17 extends inclinedly to the inner periphery and approaches the corner.

[0104] Specifically, the bottom 421a of the recess extends radially, and the bottom 421a of the recess bends outward to form the side 421b of the recess. The bottom 421a and the side 421b of the recess are connected at the corner via a connecting part 421c that protrudes outward from the recess. The extended end of the blocking part 17 is close to the connecting wall. Preferably, the connecting wall is arc-shaped, and the extension line of the blocking part 17 is perpendicular to the tangent of the connecting part 421c, so that the distance between the blocking part 17 and the connecting part 421c is relatively small, which can block foreign objects to the greatest extent.

[0105] Furthermore, the annular mounting portion 11 is coaxially arranged with the connecting wall, the connecting portion 421c is annular, the radial dimension of the inner circumference of the connecting wall is smaller than the radial dimension of the inner circumference of the annular mounting portion 11, and one end of the annular mounting portion 11 extends obliquely towards the connecting wall to form a blocking portion 17, so that the size of the blocking portion 17 gradually decreases from front to back.

[0106] Furthermore, the inner circumference of the annular mounting portion 11 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 blocking portion 17 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 blocking portion 17 is located to the other end of the annular mounting portion 11. The second step 115 is higher than the first step 114.

[0107] 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.
