Description

A button assembly and washing machine

technical field

The utility model relates to the technical field of household appliances, in particular to a button assembly. In addition, the utility model also relates to a washing machine using the button assembly.

Background technique

Washing machine is now a common household appliance. With the development of science and technology and the improvement of people's quality of life, while consumers require the performance of washing machines to be improved, their requirements for the operating experience of washing machines and the overall appearance of washing machines are also gradually increasing.

The operating structure of the existing washing machine mainly adopts two types of patch type structure and button type structure, and the button type structure is generally subdivided into two sub-categories of physical button type and touch button type. Due to factors such as single display effect and poor handling feel in the patch structure, the application of the patch operation structure is not widespread. Due to the high cost of the touch button operation structure, and the existence of factors such as easy misoperation and poor feedback, the touch button operation structure has not been widely adopted. Therefore, the operating structure of the washing machine currently on the market generally adopts the style of a physical button-type operating structure combined with a display structure.

The button in the physical button operation structure has a certain pressing stroke when it is switched on and off, so there is a degree of freedom in the installation structure of the button. Because the existing molds generally cannot ensure the matching clearance well, the buttons in the existing physical button-type operation structure will inevitably shake during use, resulting in poor handling, inflexible movements of the buttons within the range of the pressing stroke, and unilateral Pressing the button is easy to get stuck, and the buttons are not aligned in a static state, etc.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 and 2, the button assembly provided by the embodiment of the utility model includes a panel 1, a front control panel 2, a button 3 and a silicone pad 4, the button 3 is installed on the front control panel 2, and the panel 1 is provided with a The installation hole protruding from the button 3, and the silicone pad 4 is laid between the front control panel 2 and the button 3.

As shown in FIG. 3 , there are multiple keys 3 , and the key 3 includes a pressing portion 31 , a functional portion 32 and a mounting portion 33 . The pressing part 31 refers to the part that touches the finger when the button is pressed, and the upper part of the button shown in FIG. 3 is the pressing part 31 . The functional part 32 refers to the part that acts on other components after the button is pressed, and the lower part of the button shown in FIG. 3 is the functional part 32 . In this embodiment, the mounting portion 33 is located below the pressing portion 31 and located on both sides of the functional portion 32 in the width direction.

The mounting hole on the panel 1 cooperates with the pressing portion 31 , the pressing portion 31 of the button 3 is located in the mounting hole and extends outward, and the top surface of the pressing portion 31 protrudes or is flush with the top surface of the panel 1 .

As shown in FIG. 4 , the button 3 is provided with at least one slot 34 between the functional part 32 and the installation part 33 , and the front control panel 2 is provided with at least one rib 21 matching the slot 34 . When the button 3 is installed on the front control panel 2, the rib 21 is inserted into the slot 21, and the outer wall of the rib matches the inner wall of the slot. Matching means that the outer dimension of the rib is slightly smaller than the inner cavity of the slot The dimensions are roughly equal, so that the raised ribs can slide smoothly in the slot without shaking left and right.

In this embodiment, two card slots 34 are provided, and the two card slots are respectively located on both sides of the functional part 33 in the lateral direction, and the two card slots are arranged symmetrically with respect to the center line of the key. Correspondingly, the front control panel 2 is provided with two convex ribs 21 matching with the two slots on each button 3 . Further, both the slot 34 and the rib 21 are elongated, and the length direction of the slot and the rib is consistent with the movement direction of the button after being stressed.
