Description

Technical Field

[0001] This utility model relates to the field of washing machine accessories technology, specifically to a front flange structure for the inner drum of a washing machine. Background Technology

[0002] Drum washing machines originated in Europe. The washing method is designed to mimic the principle of beating clothes with a stick. They consist of a stainless steel inner drum, a mechanical program controller, an outer shell protected by phosphating, electrophoresis, and spraying, and several heavy cement blocks used to balance the huge centrifugal force generated when the drum rotates. The repeated motion, combined with the action of detergent and water, cleans the clothes.

[0003] According to the public disclosure number "A Front Flange for an Inner Drum of a Washing Machine", a front flange for an inner drum of a washing machine is disclosed. This technology discloses a technical solution such as "a front flange for an inner drum of a washing machine, including a front flange plate, a locking block provided on one side of the front flange plate, the number of the locking blocks being multiple, the multiple locking blocks being centrally symmetrically arranged, and an installation hole being provided on one side of every other locking block". It has technical effects such as "by setting multiple bends on the front flange plate, after the front flange plate is installed with the front end of the inner drum, the contact area between the front flange plate and the parts is reduced due to the bends on the front flange plate, and the bends on the front flange plate can increase the strength of the entire front flange plate, thereby reducing the wear of the front flange plate".

[0004] The flange in the above solution reduces the contact area between the front flange and the parts by setting multiple bends, and increases the flange strength. However, when the inner cylinder operates at high speed, it will impact the flange. Since the first bend in the above solution is a hollow structure, it is more likely to deform and vibrate when subjected to impact or pressure. This will not only accelerate the wear of the flange, but may also increase the noise of the equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a front flange structure for a washing machine inner drum. When the inner drum of the washing machine operates at high speed and impacts the flange, the solid circular convex ring makes the convex ring portion on the inner wall of the flange less prone to deformation, thus reducing wear on the front flange structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a front flange structure for a washing machine inner drum, comprising a front flange structure for connecting the inner drum and the outer shell of the washing machine, the front flange structure comprising:

[0007] The main components include a flange installed between the inner drum and the outer shell of the washing machine, with six circumferentially distributed mounting holes on the outer edge of the inner side of the flange;

[0008] The optimized component includes a convex ring extending outward from the inner wall of the flange, and the convex ring is a solid circle.

[0009] Reinforcing components are installed on the main body components and are used to achieve the overall strength of the main body components.

[0010] Preferably, the reinforcing component includes a reinforcing ring fixed to the front surface of the flange, six front reinforcing ribs fixed to the front surface of the flange and located between adjacent mounting holes, and several front reinforcing ribs fixed on the reinforcing ring and fixed to the flange.

[0011] Preferably, the reinforcing component further includes six rear reinforcing ribs fixed to the rear end surface of the flange and located between adjacent mounting holes, and several rear reinforcing ribs fixed inside the rear end of the flange.

[0012] Preferably, the optimized component further includes a cylindrical hole located directly in front of the mounting hole and fixed to the front end surface of the flange.

[0013] Preferably, the optimized component further includes a stiffening plate fixed between the outer wall of the borehole and the front surface of the flange.

[0014] Preferably, the optimized component further includes a first bend disposed on the inner side of the flange, the first bend being located outside the convex ring, a second bend disposed on the outer side of the flange, the second bend being located outside the first bend, and a third bend disposed on the outer edge of the flange.

[0015] Beneficial effects

[0016] This utility model provides a front flange structure for the inner drum of a washing machine. Compared with the prior art, it has the following advantages:

[0017] (1) When the front end of the flange is installed and fixed to the inner drum of the washing machine, the flange will only contact the inner drum through multiple bends, reducing the contact area and reducing wear; and when the inner drum of the washing machine impacts the flange at high speed, the convex ring is solid and circular, making the convex ring part of the inner wall of the flange less prone to deformation, reducing the wear on the front flange structure.

[0018] (2) By strengthening the overall rigidity of the structure and preventing radial deformation, and by combining the front reinforcing ribs and front reinforcing bars to increase its rigidity and strength, it effectively resists bending and torsional deformation; by using stiffeners to prevent radial deformation around the mounting holes, it avoids deformation or even breakage after screws are inserted into the mounting holes on the flange for installation, which would affect the sealing effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a front flange structure for a washing machine inner drum, including a front flange structure 1 for connecting the inner drum and the outer shell of the washing machine, the front flange structure 1 including:

[0027] The main component 11 includes a flange 111 installed between the inner drum and the outer shell of the washing machine, and six circumferentially distributed mounting holes 112 opened on the inner outer edge of the flange 111.

[0028] The optimized component 12 includes a convex ring 121 extending outward from the inner wall of the flange 111, and the convex ring 121 is a solid circle.

[0029] The reinforcing component 13 is disposed on the main body component 11 and is used to enhance the overall strength of the main body component 11.

[0030] In this embodiment, after the front end of the flange 111 is installed and fixed to the inner drum of the washing machine, the flange 111 will only contact the inner drum through multiple bends; and when the inner drum of the washing machine impacts the flange 111 at high speed, the convex ring 121 is solid and circular, so the convex ring 121 part of the inner wall of the flange 111 is not easily deformed, reducing the wear on the front flange structure 1.

[0031] Specifically, the reinforcing component 13 includes a reinforcing ring 131 fixed to the front surface of the flange 111, six front reinforcing ribs 132 fixed to the front surface of the flange 111 and located between adjacent mounting holes 112, and several front reinforcing ribs 133 fixed on the reinforcing ring 131 and fixed to the flange 111.

[0032] In this embodiment, the overall rigidity of the structure is enhanced and radial deformation is prevented by reinforcing ring 131, and the front reinforcing rib 132 and front reinforcing rib 133 are used to increase its rigidity and strength, effectively resisting bending and torsional deformation.

[0033] Specifically, the reinforcing component 13 also includes six rear reinforcing ribs 134 fixed to the rear end surface of the flange 111 and located between adjacent mounting holes 112, and several rear reinforcing ribs 135 fixed inside the rear end of the flange 111.

[0034] In this embodiment, the functions of the rear reinforcing rib 134 and the rear reinforcing rib 135 are the same as those of the front reinforcing rib 132 and the front reinforcing rib 133.

[0035] Specifically, the optimized component 12 also includes a cylindrical hole 125 located directly in front of the mounting hole 112 and fixed to the front end surface of the flange 111.

[0036] In this embodiment, the stiffener 126 prevents radial deformation around the mounting hole 112, thus avoiding deformation or even breakage after screws are inserted into the mounting hole 112 on the flange 111 for installation, which would affect the sealing effect.

[0037] Specifically, the optimized component 12 also includes a stiffening plate 126 fixed between the outer wall of the cylinder bore 125 and the front surface of the flange 111.

[0038] In this embodiment, the strength between the cylindrical hole 125 and the flange 111 is improved by the stiffening plate 126.

[0039] Specifically, the optimized component 12 also includes a first bend 122 disposed inside the flange 111 and located outside the convex ring 121, a second bend 123 disposed outside the flange 111 and located outside the first bend 122, and a third bend 124 disposed on the outer edge of the flange 111.

[0040] In this embodiment, multiple bends on the flange 111 reduce the contact area after installation with the inner drum of the washing machine, thereby reducing wear and extending service life.

[0041] The working principle and usage process of this utility model are as follows: First, after the front end of the flange 111 is fixed to the inner drum of the washing machine, the flange 111 will only contact the inner drum through multiple bends, reducing the contact area and reducing wear. Furthermore, when the inner drum of the washing machine operates at high speed and impacts the flange 111, the solid circular shape of the convex ring 121 makes the convex ring 121 part of the inner wall of the flange 111 less prone to deformation, reducing the wear on the front flange structure 1. The reinforcing ring 131 enhances the overall rigidity of the structure and prevents radial deformation, and works in conjunction with the front reinforcing rib 132 and the front reinforcing rib 133 to increase its rigidity and strength, effectively resisting bending and torsional deformation. The rib plate 126 prevents radial deformation around the mounting hole 112, avoiding deformation or even breakage after screws are inserted into the mounting hole 112 on the flange 111 for installation, which would affect the sealing effect.
