Wherein, the sealing gasket 4 comprises a surface arranged on the hinge seat 3 in the hinge installation area 2, and a first sealing surface 401 which at least covers the first shell 301 and the second shell 302 and is exposed at the buckling position of the hinge installation area 2; the first sealing surface 401 comprises a horizontal sealing surface which covers the hinge base 3 at the mounting opening and is exposed on the surface of the hinge mounting area 2; a side wall sealing surface which is connected with the horizontal sealing surface and extends outwards along the side wall of the hinge base 3 extending out of the mounting opening; the horizontal sealing surface and the side wall sealing surface are formed in the hinge mounting area 2, so that water is prevented from entering the sealing structure inside the dish seat 1 from the joint of the first shell 301 and the second shell 302, and washing water in the hinge mounting area 2 is prevented from entering the dish seat 1 from the joint of the hinge seat 3 which is in the joint by arranging the first sealing surface 401 and the second sealing surface 402 which wrap the hinge seat 3 and are exposed in the hinge mounting area 2.
Furthermore, an included angle for enabling the side wall sealing surface to be attached to the side wall of the hinge seat 3 is formed between the horizontal sealing surface and the side wall sealing surface; preferably, the included angle is an obtuse angle.
Further, the first sealing surface 401 is made of a high-elasticity rubber material, and the high-elasticity rubber material ensures that the horizontal sealing surface and the side wall sealing surface of the first sealing surface 401 form a sealing structure which tightly wraps the hinge base 3 at the mounting opening and is exposed on the surface of the hinge mounting area 2.
In a specific embodiment, as shown in fig. 2 to 6, the sealing structure of the tray 1 of the washing machine according to this embodiment further includes a pressing rib 7 connected to the second pressing surface 6 and distributed from far to near with respect to the hinge base 3; extrusion muscle 7 orientation 4 one side direction of sealed pad is protruding, particularly, through setting up extrusion face and extrusion muscle 7, right sealed pad 4 produces the extrusion force of different degrees, and then makes sealed pad 4 produce the deformation of different degrees, reaches multiple sealed effect, furtherly, through setting up two different extrusion faces for the lateral wall of hinge seat 3 and hinge seat 3 butt portion 8 all obtains fine sealing, has avoided the washing water to get into from the seam of the hinge seat 3 lateral wall of lock the inside of dish seat 1.
Further, the amount of deformation generated when the pressing rib 7 presses the third sealing surface 403 is greater than the amount of deformation generated when the second pressing surface 6 presses the fourth sealing surface 404, and because the amount of deformation of the gasket 4 in the two sealing areas is different, the sealing effect of the gasket 4 in the two sealing areas is different, so that multiple sealing is formed, and the possibility that the gasket 4 is pressed to be pulled out is reduced.
In a specific embodiment, as shown in fig. 2 to 4, in the sealing structure of the washing machine tray 1 according to the present invention, a sealing structure is formed between the tray 1 and the hinge base 3, a pressing structure is disposed at a contact portion between the tray 1 and the hinge base 3, the pressing structure surrounds the mounting opening and is disposed at one side facing the inside of the tray 1, the hinge base 3 is provided with the abutting portion 8 corresponding to the pressing structure, a sealing gasket 4 is disposed between the pressing structure and the abutting portion 8, the pressing structure presses the sealing gasket 4, and under a combined action of the abutting portion 8, the sealing gasket 4 is deformed to realize sealing between the tray 1 and the hinge base 3.
Further, in order to facilitate the observation of the sealing structure between the disc seat 1 and the hinge seat 3, as shown in fig. 4, as can be seen from the schematic diagram of the enlarged portion in fig. 4, the pressing structure presses the sealing gasket 4 to generate deformation, the cross-section portion in fig. 4 is that the pressing structure presses the deformation generated by the abutting portion 8, specifically, the sealing gasket 4 is arranged in a step shape, which avoids the situation that the sealing effect is not good when the sealing gasket 4 is pressed by the pressing structure of the disc seat 1, the multi-layer sealing ensures the sealing effect, as can be seen from fig. 4, the pressing structure presses the abutting portion 8 to form a plurality of sealing areas, which are a first area 9, a second area 10, a third area 11 and a fourth area 12, respectively, wherein the deformation amount of the sealing gasket 4 in the first area 9 is greater than that of the sealing gasket 4 in the second area 10, due to the arrangement, when the sealing gasket 4 is extruded by the extrusion structure, the situation that the sealing gasket 4 is separated is avoided, the extrusion force applied to the sealing gasket 4 is tight at the outside and loose at the inside, the sealing gasket 4 tends to be folded towards the side wall of the hinge seat 3, further, the third area 11 covers the joint where the first shell 301 and the second shell 302 are buckled, and water drops formed by condensation of washing water or steam are prevented from flowing into the hinge seat 3 and the disc seat 1 from the joint to further cause pollution; meanwhile, a fourth area 12 is arranged between the first area 9 and the second area 10, the fourth area 12 is a hollow sealing area which is at least partially filled with air, and when the first area 9 or the second area 10 fails, the fourth area 12 can form a buffer zone to prevent the washing water from directly flowing into the inner wall of the disk seat 1.
In a specific embodiment, at least the cross section of the portion where the extrusion rib 7 and the sealing gasket 4 are matched is an arc shape, and the extrusion rib 7 shown in fig. 6 is a planar structure, and in practical application, may be configured as an arc-shaped surface to enhance the sealing effect.
In a specific embodiment, the cross section of the extrusion rib 7 and the cross section of the sealing gasket 4 at the matching part are at least two adjacent arc-shaped cross sections, and at least two arcs are arranged, so that when the extrusion rib 7 is matched with the sealing gasket 4, a multi-sealing effect can be generated, the sealing between the disc seat 1 and the hinge seat 3 is ensured, and washing water is prevented from entering the disc seat 1; further, the radius of the arc-shaped cross section of one side far away from the hinge seat 3 is larger than or equal to the radius of the arc-shaped cross section of one side close to the hinge seat 3.
