Abstract
Description
Technical Field
[0001] The present application relates to the technical field of household appliances, and in particular to a button structure and a washing machine. Background Art
[0002] Currently, washing machine button control methods are primarily divided into two types: touch control buttons and physical buttons. Touch control buttons, based on capacitive or resistive sensing technology, can sense the touch position of a user's finger and convert that touch position into an electrical signal, enabling user input. Touch control buttons are increasingly popular in modern designs due to their superior feel, but they are relatively expensive. Physical buttons, which control the flow of current through mechanical force, offer a superior feel but also place higher demands on assembly precision. Small gaps between buttons can cause the buttons to become stuck, preventing timely feedback.
[0003] Therefore, the smoothness and reliability of keystrokes still need to be further improved. Utility Model Content
[0004] In view of this, the purpose of this application is to provide a button structure and a washing machine.

Any embodiment described in this application as exemplary is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present application.

It should be understood that one of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is to be consistent with the widest scope consistent with the principles disclosed herein.
[0040] To facilitate understanding of the solution of the present application, the spline curves and arrows used in the drawings are explained here: the components indicated by the spline curves without arrows are solid components, that is, components with solid structures; the components indicated by the spline curves with arrows are virtual components, that is, components without solid structures.
[0041] First, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The present application provides a key structure 100, including: a panel 20, provided with a hollow portion 21; and a key body 10, the key body 10 includes a pressing column 11, a pressing tube 12 and an elastic connecting portion 13 fixedly connected in sequence, the pressing column 11 passes through the hollow portion 21 to form a first pressing end 111 and a trigger end 112 arranged oppositely, the pressing tube 12 is sleeved on the outer peripheral side of the pressing column 11, the elastic connecting portion 13 is fixedly connected to the side wall of the hollow portion 21 and the outer peripheral wall of the pressing tube 12, and the trigger end 112 is used to trigger the touch switch 30.
[0042] In the key structure 100 provided in the present application, the key body 10 includes a pressing column 11, a pressing cylinder 12 and an elastic connecting part 13 fixedly connected in sequence. When operation control is required, the first pressing end 111 of the pressing column 11 can be pressed to move the key body 10 toward the touch switch 30, and the trigger end 112 of the pressing column 11 contacts the touch switch 30. After the pressing is completed, the first pressing end 111 is released, and the pressing column 11, the pressing cylinder 12 and the elastic connecting part 13 recover their deformation under the action of elasticity, and the trigger end 112 is separated from the touch switch 30. The arrangement of the pressing column 11, the pressing cylinder 12 and the elastic connecting part 13 can promote the rebound of the key body 10 after being pressed, avoiding the problem that the trigger end 112 is stuck with the touch switch 30 to cause no key feedback, and the trigger end 112 continues to contact the touch switch 30 to cause the control system to malfunction. The key structure 100 provided in the present application can improve the smoothness and reliability of key operation.
[0043] It should be noted that in the key structure 100 provided in the present application, the distance between the trigger end 112 and the touch switch 30 can be shorter, so that when the pressing column 11 is pressed, the pressing column 11 moves a shorter distance, thereby allowing the user to obtain an experience similar to that of a touch button. At the same time, the structural setting of the key body 10 can maintain good key feedback even in a shorter displacement, thereby improving the smoothness and reliability of the key operation.
[0044] In some embodiments, see Figure 6 and Figure 7 The trigger end 112 extends to the side of the pressing cylinder 12 away from the panel 20. It should be noted that when the pressing post 11 is pressed, the pressing cylinder 12 does not contact the trigger switch. Extending the trigger end 112 to the side of the pressing cylinder 12 away from the panel 20 promotes effective contact between the trigger end 112 and the touch switch 30 when pressed. Even when there is a large gap between the first pressing end 111 and the touch switch 30, good key feedback can be obtained.
[0045] In some embodiments, the first pressing end 111 is immersed in the pressing tube 12, and a second pressing end 121 is formed on the pressing tube 12 around one end surface of the first pressing end 111. Specifically, when the key structure 100 is in use, when the user's hand presses the key body 10, the fingertips press on the first pressing end 111, and the surrounding areas of the fingertips press on the second pressing end 121. The first pressing end 111 is immersed in the pressing tube 12, so that the arrangement of the first pressing end 111 and the second pressing end 121 conforms to the design of the fingertips and the surrounding skin, which is conducive to improving the user's feel when pressing; and after the trigger end 112 contacts the touch switch 30, it can prevent the touch switch 30 from lifting the pressing column 11 so that the first pressing end 111 is higher than the pressing tube 12, affecting the pressing feel.
[0046] In some embodiments, the key structure 100 further includes a plurality of connecting ribs 14, which connect the outer peripheral wall of the pressing column 11 and the inner side wall of the pressing tube 12. In other words, the connection structure between the pressing column 11 and the pressing tube 12 is hollow. Furthermore, the plurality of connecting ribs 14 are arranged on a side close to the trigger end 112. In this way, when the trigger end 112 is pressed to contact the touch switch 30, the elastic potential energy of the connecting rib 14 can be effectively increased, so that when the first pressing end 111 is released, the key body 10 obtains a greater rebound force, promotes rebound, and improves the smoothness and reliability of the key.
[0047] In some embodiments, the side surface of the elastic connection portion 13 away from the trigger end 112 is immersed in the hollow portion 21 to be located between the two opposite surfaces of the panel 20. In this way, the button body 10 can have a better rebound effect after being pressed.
[0048] In some embodiments, the side surface of the elastic connection portion 13 away from the trigger end 112 is located between the two end surfaces of the pressing cylinder 12. In other words, when pressing the key body 10, the finger mainly contacts the pressing column 11 and the pressing cylinder 12, which can ensure the resilience of the elastic connection portion 13 and avoid the key being stuck and causing no key feedback.
[0049] In some embodiments, the elastic connection portion 13 is a hollow structure, which can promote air circulation on both sides of the elastic connection portion 13, enhance its recovery ability after elastic deformation, thereby improving the rebound performance of the key body 10 and making the key body 10 have better key feedback.
[0050] In some embodiments, the panel 20 is covered with a film 22. The film 22 can effectively prevent scratches and abrasions on the panel 20, protecting the paint or raw materials on the surface of the panel 20 from damage. The film 22 has good density, which can prevent dust and dirt from contaminating the panel 20, keeping the panel 20 clean and beautiful.
[0051] Furthermore, the surface of the disk membrane 22 is flush with the end surface of the pressing tube 12. In this way, the key structure 100 is similar to a touch key in appearance and feel, which improves the user experience.
[0052] In some embodiments, the panel 20 and the key body 10 are integrally formed. Specifically, the elastic connector 13 is integrally formed with opposing surfaces of the panel 20. This integral molding reduces the number of components and enhances the resilience of the key body 10 after being pressed, improving key feedback.
[0053] In some embodiments, the panel 20 is provided with a plurality of hollow portions 21, and the key structure 100 includes a plurality of key bodies 10, which are matched one to one with the plurality of hollow portions 21. It is understood that there is an appropriate gap between adjacent key bodies 10 to prevent mutual interference between the key bodies 10.
[0054] Second, see Figure 8 、 Figure 9 、 Figure 10 and Figure 11 , an embodiment of the present application further provides a washing machine, which includes the above-mentioned button structure 100.
[0055] It should be noted that the washing machine provided in this application can be a pulsator washing machine or a drum washing machine. In a pulsator washing machine, the button structure 100 can be set on the top of the pulsator washing machine. In a drum washing machine, the button structure 100 can be set on the front panel 20 of the drum washing machine, that is, above the clothing loading port.
[0056] It can be understood that the panel 20 can be an operating panel of a washing machine.
[0057] In some embodiments, the washing machine further includes a plurality of touch switches 30, which are connected to the washing machine's control system. The washing machine also includes a plurality of button bodies 10, which are associated with the plurality of touch switches 30. It will be appreciated that different button bodies 10 can trigger corresponding touch switches 30 to activate different laundry programs, such as washing, rinsing, spinning, and drying.
[0058] The washing machine provided in the present application adopts the above-mentioned button structure 100. Through the structural setting of the button body 10 of the pressing column 11, the pressing cylinder 12 and the elastic connecting part 13, a button structure 100 with high smoothness and reliability can be obtained at a lower production cost. It not only provides a feel similar to that of a touch button, but also ensures better button feedback, greatly improving the user experience.
[0059] The basic concepts have been described above. It will be apparent to those skilled in the art that the detailed disclosure above is merely illustrative and does not limit the present application. Although not explicitly stated herein, those skilled in the art may make various modifications, improvements, and amendments to the present application. Such modifications, improvements, and amendments are suggested in the present application and remain within the spirit and scope of the exemplary embodiments of the present application.
