Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, specifically to a spinning die-formed door ring structure for washing machines. Background Technology

[0002] The door ring structure of a washing machine, as a key component connecting the lid and the inner drum, not only guides the opening and closing of the door but also performs multiple functions such as sealing, waterproofing, and protection. In existing technologies, door rings are mostly injection molded or welded together, with their structures typically vertically positioned and welded to the door or the front of the drum. Due to the heat-affected zone of the welded structure, burrs or minor unevenness are easily generated at the interface, leading to scratches and jamming during door opening and closing, and the insertion or removal of linens. This poses a risk of abrasion, especially when washing delicate fabrics, affecting the user experience. Furthermore, traditional door ring structures often involve a rigid vertical press-fit with the sealing ring, resulting in uneven stress on the sealing ring over time. This can lead to localized compression, aging, and damage, causing a decline in sealing performance and affecting the reliability and safety of the entire machine.

[0003] In view of the above, this application proposes a spinning molding door ring structure for washing machines. By using a spinning molding method and an inclined connection angle design, the structural fit between the door ring, the sealing ring, the inner drum, and the loading door is optimized to improve the structural sealing performance, prevent scratching of linens, and extend the service life of the sealing components, thereby improving the overall safety and practicality of the washing machine product. Utility Model Content

[0017] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0019] This application proposes a spin-molded door ring structure for a washing machine, as detailed below:

[0020] For reference Figure 1-3 This application mainly consists of a large cover 1, an inner roller 2, a hinge seat 3, a garment door 4, a round shaft 5, a spacer 6, a door ring 7, and a right-angle shaft 8 working together to reduce the burrs that easily scratch the linens in the existing welding method, while further optimizing the structural form to reduce the risk of scratching the linens.

[0021] For reference Figure 1-3 The large cover 1 and the inner roller 2 located on the rear side of the large cover 1 are provided. The large cover 1 is provided with a hinge seat 3, and the hinge seat 3 is connected to the loading door 4. The inner roller 2 is inclined at one end facing the loading door 4. A round shaft 5 is spun on the end of the inner roller 2 facing the loading door 4. The round shaft 5 is located at the bottom of one side of the inner roller 2, facing downward and towards the loading door 4 (the other side is in the direction of the loading door 4).

[0022] Furthermore, the top of the round shaft 5 is set horizontally, and an acute-angled gap 6 is formed between it and the inner roller 2. The gap 6 can achieve the effect of dispersing stress during operation. When it is impacted, a part of the stress can be diverted from the gap 6, achieving the effect of stress diversion. At the same time, the horizontal setting of the top of the round shaft 5 can also complete the work better during spinning. The spinning method reduces the damage caused by burrs in most existing welded connections, and its surface is smoother.

[0023] For reference Figure 1 The cover 1 is provided with a door ring 7. The end of the door ring 7 facing the loading door 4 is inclined to correspond to the inner roller 2. A right angle shaft 8 is spun on the end of the door ring 7 facing the loading door 4. One end of the right angle shaft 8 is connected to one side edge of the door ring 7, and the other end is oriented with one side edge facing the door ring 7, so that the side facing the loading door 4 has a smoother contact surface, which also reduces the occurrence of scratches and other problems.

[0024] For reference Figure 1-3The garment door 4 is equipped with a sealing ring 41. The sealing ring 41 mainly serves to seal the gaps at the joints, improve air tightness and water tightness, and prevent water and air leakage. It is a common existing installation method, and this application will not elaborate on it further.

[0025] For reference Figure 1-3 One end of the right-angle shaft 8 is connected to one side edge of the door ring 7, and the other end is positioned with one side edge facing the door ring 7. When the right-angle shaft 8 is connected to the door ring 7, it contacts the sealing ring 41. The bottom of the right-angle shaft 8 is relatively smooth and directly contacts the sealing ring 41, which can increase the service life of the sealing ring 41 and reduce the probability of its damage. At the same time, the side with the edge of the linen is also lowered, reducing the occurrence of it scratching the linen.

[0026] For reference Figure 1-3 In this application, an electronic door lock 9 is provided on the side of the cover 1 away from the hinge seat 3. The electronic door lock 9 is connected to the latch on one side of the garment door 4. The electronic door lock 9 facilitates the opening and closing of the door, which is opposite to the movement of the hinge seat 3.

[0027] For reference Figure 4 The figure includes a comparison of the existing inner roller 101, existing door ring 701, and existing sealing ring 401 with the structure of this application. Existing models mostly use welding on one side of the inner roller 101, which inevitably results in some burrs. Furthermore, the existing roller is vertically oriented, which, compared to the inclined design of this application, results in a smaller gap between it and the garment door, making it more prone to catching linens when the door is closed. Similarly, the existing door ring 701 is also vertically oriented, and its direct pressing contact with the existing sealing ring 401 can lead to friction over time, causing damage to the sealing ring 401 and reducing its sealing effect. The bent design of this application reduces the risk of damage.

[0028] In this invention, the working steps of the device are as follows:

[0029] Step one: The user first opens the garment door 4, which is hinged to the cover 1 via the hinge seat 3. During the opening process, the door ring 7 also opens synchronously with the garment door 4. Because the door ring 7 is inclined towards the garment door 4, it provides more space for movement between itself and the inner roller 2 when opening, reducing the risk of jamming. At the same time, one end of the door ring 7 has a right-angle shaft 8 formed by spinning. One end of the shaft is connected to the side edge of the door ring 7, and the other end facing the garment door 4 is a smooth contact surface, which effectively reduces friction or scratching with the linens during opening and closing. Step two: The user puts the linens to be washed into the inner roller 2. Compared with the existing vertical arrangement, the inner roller 2 is arranged inclined towards the garment door 4, and a round shaft 5 is formed by spinning at the bottom of the door end. The top of the round shaft 5 is horizontal and forms an acute angle gap 6 with the inner roller 2. This arrangement not only prevents the linens from contacting burrs during insertion, but also plays a role in buffering and stress dispersion during operation, thereby improving the overall structural stability of the roller. Step 3: The user closes the loading door 4, ensuring it seals tightly against the door ring 7 on the main cover 1. Due to the inclined structure of the door ring and the smooth connection of the right-angle shaft 8, the door is easier to align and position when closed, resulting in a tight fit. This reduces the risk of reduced sealing due to assembly errors and avoids the risk of damage caused by direct vertical pressure on the existing sealing ring 401. Step 4: During operation, if linens accumulate or experience slight impact while the inner drum 2 is rotating at high speed, the acute-angle structure of the interval 6 effectively buffers stress and guides the flow. Simultaneously, the flat structure at the top of the round shaft 5 enhances the stability of the spun connection, preventing abnormal vibrations or structural damage during operation. Step 5: After the washing cycle ends, the user reopens the loading door 4. Thanks to the aforementioned structural optimization, the angle between the loading door 4 and the door ring 7 is more optimized when removing linens, preventing linen clamping, scratching, or blockage, thus providing a more convenient and safer daily user experience.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
