Description

Technical Field

[0001] This application relates to the field of home appliance technology, specifically providing a display device and a home appliance. Background Technology

[0002] A dishwasher is a modern appliance that automatically cleans bowls, chopsticks, plates, dishes, and other tableware. With socio-economic development and rising living standards, dishwashers have gradually transformed from a luxury item into an everyday necessity for many families. They not only significantly reduce the workload for family members and improve the efficiency of housework, but also effectively ensure the cleanliness and hygiene of tableware, bringing users a more comfortable and convenient living experience.

[0003] In current dishwasher technology, to meet users' demands for ease of operation and aesthetics, many dishwashers adopt a rotating display screen or control panel design. While this design improves the user experience to some extent, it still presents some technical challenges in practical application. Specifically, in the current dishwasher display screen or control panel's flip design, the relatively large clearance between the transmission system and the flipping mechanism easily causes the display screen or control panel to wobble during the flipping process. This not only makes it difficult to stabilize in the preset position but also produces a clicking or rattling noise, significantly impacting the user experience.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] This application aims to solve the aforementioned technical problem, namely, to address the issue that the existing dishwasher display screen or control panel's flip structure is prone to shaking during use, resulting in a poor user experience.

[0038] Please refer to Figure 1-2 This is a display device 1 according to an embodiment of the present application, which aims to solve the problem of shaking when the display device 1 of a household appliance is flipped in the related art.

[0039] Specifically, the display device 1 includes a mounting frame 11 and a screen assembly 21 connected to the mounting frame 11. The mounting frame 11 serves as the supporting structure for the entire display device 1, providing a stable mounting base for the screen assembly 21 and also facilitating connection to the main body of the household appliance. The screen assembly 21 is the core component of the entire display device 1, comprising two main parts: a support frame 211 and a display screen 212. The support frame 211, as the basic structure of the display screen 212, provides support, protection, and adjusts the angle of the display screen 212. The display screen 212, mounted on the support frame 211, is the core component for displaying information and the user interface. The support frame 211 and the mounting frame 11 are hinged via a hinge shaft 210, allowing the support frame 211 to rotate around the hinge shaft 210.

[0040] In one embodiment, the driving scheme of the display device 1 adopts a structure in which the drive motor 41 drives the connecting rod 42 to realize the rotation function of the screen assembly 21.

[0041] Specifically, the drive motor 41 is mounted on the mounting bracket 11, serving as the power source for the entire system. The drive motor 41 is typically a stepper motor, characterized by its small size, moderate power, and high control precision. One end of the connecting rod 42 is connected to the drive end of the drive motor 41 via a mechanical connector, while the other end is fixedly connected to the support frame 211. Power is output from the drive end of the drive motor 41. When the drive motor 41 starts, its output end drives the support frame 211 to rotate around the hinge axis 210 via the connecting rod 42, thereby allowing precise control of the rotation angle and speed of the support frame 211.

[0042] Furthermore, to enhance the stability of the screen assembly 21's rotation, a damping component 30 is provided between the mounting bracket 11 and the support bracket 211. Located at the hinge joint, the damping component 30 provides a damping force when the support bracket 211 rotates. This damping force reduces mechanical impact, making the screen assembly 21's flipping process smoother. Simultaneously, it allows the support bracket 211 to remain stable at any angle without swaying or shifting due to gravity or other external forces. This design effectively solves the problem of wobbling inherent in traditional flip structures, improving the operational feel and user experience.

[0043] In one embodiment, the display device 1 employs two sets of damping components 30, which are respectively disposed at both ends of the support frame 211 so that the support frame 211 can be subjected to uniform damping force during rotation.

[0044] In one embodiment, the mounting frame 11 and the support frame 211 are respectively provided with a first hinge seat and a second hinge seat 302 for connecting and rotating the two. Specifically, the first hinge seat is located on the mounting frame 11 near the hinge connection, and has a first through hole at its center; the second hinge seat 302 is located on the support frame 211 near the hinge connection, and has a second through hole 300 at its center. Both the first through hole and the second through hole 300 are coaxially arranged with the hinge shaft 210.

[0045] In one embodiment, reference Figure 4 To allow for more flexible installation and adjustment of the damping component 30, the display device 1 further includes a first connector 31 and a second connector 32. The first connector 31 and the second connector 32 are two separate components. The first connector 31 is connected to the mounting bracket 11, and a first hinge seat is disposed on the first connector 31 near the hinge point. Similarly, the second connector 32 is connected to the support bracket 211, and a second hinge seat 302 is disposed on the second connector 32 near the hinge point.

[0046] By introducing intermediate connectors, even if the original structure of the mounting bracket 11 and the support bracket 211 is not designed with a hinge for mounting the damping component 30, it can be extended through connectors to better adapt to the structure of the mounting bracket 11 and the support bracket 211.

[0047] Furthermore, this design avoids significant modifications to the existing display device 1. Damping force can be added simply by installing appropriate connectors on the mounting bracket 11 and support bracket 211, thereby improving the stability of the display device 1 and the user experience. This is a cost-effective solution for upgrading and modifying existing equipment.

[0048] Furthermore, the damping assembly 30 includes a damping shaft 33 and a damping pad 34. The damping shaft 33 passes through a first through hole and a second through hole 300, and the damping pad 34 is snapped onto the damping shaft 33. The material of the damping pad 34 is typically an elastic material with a high coefficient of friction, such as rubber or polyurethane, to ensure that it can generate sufficient frictional force.

[0049] In one implementation, the damping pad 34 abuts against the first hinge seat. When the support frame 211 rotates, the friction between the damping pad 34 and the first hinge seat will hinder the movement of the support frame 211, forming a damping force, thereby achieving a smooth rotation effect. At the same time, under the action of this damping force, the support frame 211 can stay at a certain position.

[0050] In one implementation, the damping pad 34 abuts against the second hinge seat 302. When the support frame 211 rotates, the friction between the damping pad 34 and the second hinge seat 302 will hinder the movement of the support frame 211, forming a damping force, thereby achieving a smooth rotation effect. At the same time, under the action of this damping force, the support frame 211 can stay at a certain position.

[0051] In one implementation, two sets of damping pads 34 are provided, and the two sets of damping pads 34 abut against the first hinge seat and the second hinge seat 302 respectively. When the support frame 211 rotates, the friction between the damping pads 34 and the first hinge seat and the second hinge seat 302 respectively will hinder the movement of the support frame 211, forming a damping force, thereby achieving a smooth rotation effect. At the same time, under the action of this damping force, the support frame 211 can stay at a certain position.

[0052] In summary, the damping pad 34, through frictional contact with the first hinge seat or the second hinge seat 302, can not only effectively prevent the support frame 211 from shaking during rotation, but also make it stay stably at any angle without the need for an additional locking device.

[0053] In one embodiment, reference Figure 2 and 3The damping shaft 33 is provided with a first locking groove 331 and a second locking groove 332, which are used to fix the first damping pad 341 and the second damping pad 342, respectively. The first locking groove 331 is located at one end of the damping shaft 33, and the second locking groove 332 is located at the other end of the damping shaft 33. Through the design of the locking grooves, the damping pad 34 can be firmly fixed on the damping shaft 33, preventing it from loosening or falling off when the support frame 211 rotates.

[0054] Furthermore, the damping pad 34 includes a first damping pad 341 and a second damping pad 342, which are respectively engaged with the first locking groove 331 and the second locking groove 332. After the first damping pad 341 is engaged with the first locking groove 331, it abuts tightly against the first hinge seat, generating damping force through friction, thereby limiting the rapid movement of the support frame 211. The second damping pad 342 is engaged with the second locking groove 332 and abuts against the second hinge seat 302, similarly generating damping force through friction.

[0055] In this way, the first damping pad 341 and the second damping pad 342 act on the first hinge seat and the second hinge seat 302 respectively, forming a dual damping effect, which further improves the rotational smoothness and positioning stability of the support frame 211.

[0056] In one embodiment, the damping force is adjusted by changing the number of the first damping pad 341 and the second damping pad 342, thereby meeting the needs of different usage scenarios.

[0057] For example, if a user needs to install a heavier screen on the display device 1, the number of the first damping pad 341 and the second damping pad 342 can be increased to provide greater damping force, ensuring that the screen can stay stably at any angle and will not slide on its own due to gravity.

[0058] Furthermore, by adjusting the number of damping pads 34, the damping force can be finely adjusted. For example, by gradually increasing or decreasing the number of damping pads 34, the optimal damping effect can be gradually tested and adjusted to meet the specific needs of different users.

[0059] In one embodiment, the damping assembly 30 employs a damping bearing design. The damping bearing is disposed between the outer peripheral wall of the hinge shaft 210 and the support frame 211, forming a friction damping layer to dampen the force during the rotation of the support frame 211.

[0060] Specifically, when the support frame 211 rotates around the hinge shaft 210, the damping bearing can generate appropriate damping force through its internal friction material, effectively slowing down the rotation speed, thereby achieving a smooth and stable damping effect.

[0061] In another embodiment, the damping component 30 employs an elastic element design to achieve a damping effect on the rotation of the support frame 211.

[0062] Specifically, the elastic element is sleeved on the hinge shaft 210, with one end abutting against the mounting bracket 11 and the other end abutting against the support frame 211. When the support frame 211 rotates relative to the mounting bracket 11, the elastic element generates resistance due to deformation, thus playing a damping role. This design, which controls the rotation speed through the elastic force of the elastic element, gives the support frame 211 a certain resistance during rotation, preventing it from swaying. Moreover, this design is not only simple in structure and easy to install and maintain, but also relatively low in cost.

[0063] This embodiment also provides a household appliance, including the display device 1 as described above. Since the display device 1 already has the above-mentioned beneficial effects, the household appliance can provide users with a better display experience during use, ensuring that the screen can remain stably in its position at any angle.

[0064] In one embodiment, the household appliance is a dishwasher. Because the dishwasher is equipped with the display device 1 as described above, the damping component 30 provides appropriate resistance, allowing the user to operate the appliance more precisely and comfortably when adjusting the angle of the display screen 212 to view the washing progress or select a program. This not only improves product performance and user experience but also enhances its competitive advantage in the market.

[0065] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
