In the washing machine 1 provided by this embodiment, the supporting member 124 extending toward the hole wall of the mounting hole 122 is disposed on the key 123, or the supporting member 124 extending toward the key 123 is disposed on the hole wall of the mounting hole 122, so that the supporting member 124 is supported between the key 123 and the hole wall of the mounting hole 122, and the key 123 is prevented from shifting downward under the action of its own gravity, and thus the preset mounting gap T is always provided between the lower edge 123a of the supporting member 124 and the lower hole wall 122a of the mounting hole 122, so that the key 123 can be kept at its preset mounting position, and the sensitivity of pressing the key 123 is further improved.
Optionally, the abutting portion of the supporting member 124 and the lower hole wall 122a of the mounting hole 122 or the abutting surface 124a of the lower edge 123a of the key 123 are curved surfaces, so as to reduce the contact area between the supporting member 124 and the lower hole wall 122a of the mounting hole 122 or the lower edge 123a of the key 123, and improve the convenience of pressing the key 123.
That is, when the abutting portion of the support 124 abuts against the lower hole wall 122a of the installation hole 122, the abutting portion and the lower hole wall 122a of the installation hole 122 form an abutting surface 124a, and the abutting surface 124a may be a curved surface, such as a wave-shaped curved surface, to reduce the contact area between the support 124 and the lower hole wall 122a of the installation hole 122. Optionally, the curved surface is a circular arc surface to further reduce the contact area between the support 124 and the lower hole wall 122a of the mounting hole 122.
When the abutting portion of the supporting member 124 abuts against the lower edge 123a of the key 123, the abutting surface 124a is formed at the portion where the abutting portion contacts with the lower edge 123a of the key 123, and the abutting surface 124a may be a curved surface, such as a wave-shaped curved surface, to reduce the contact area between the supporting member 124 and the lower edge 123a of the key 123. Optionally, the curved surface is a circular arc surface to further increase the contact area between the supporting member 124 and the lower edge 123a of the key 123.
Of course, the structure of the abutting portion is not limited thereto. For example, the abutting portion and the lower hole wall 122a of the mounting hole 122 or the abutting surface 124a of the lower edge 123a of the key 123 are flat surfaces, and two opposite sides of the flat surfaces extend outward to form arc surfaces.
Alternatively, the support 124 includes a columnar portion having an axial direction parallel to the pressing direction of the key 123. That is, the axial direction of the columnar portion of the support 124 extends in the front-rear direction to reliably support the key 123, improving the positioning reliability of the key 123, and thus reliably making the lower edge 123a of the support 124 and the lower hole wall 122a of the mounting hole 122 always have the predetermined mounting gap T therebetween. The column-shaped portion may be a semi-cylinder, and thus, the abutting portion of the column-shaped portion has a smooth contact surface, so that the contact area between the column-shaped portion and the hole wall of the mounting hole 122 or the edge of the key 123 can be reduced.
The columnar part comprises a front end face facing a user, a rear end face opposite to the front end face and a side face located between the front end face and the rear end face, the joint of the front end face and the side face is in smooth transition, so that the contact area of the joint of the front end face and the side face and the hole wall of the mounting hole 122 or the edge of the key 123 is further reduced, and the phenomenon of blocking and stopping during the pressing operation process of the key 123 can be reduced.
Of course, the structure of the supporting member 124 is not limited thereto, and the embodiment is only illustrated here. For example, the support 124 may also be conical or hemispherical. When the supporting member 124 is tapered, the large end of the tapered supporting member 124 can be a connecting portion, and the small end can be an abutting portion; when the supporting member 124 has a hemispherical shape, the spherical surface of the hemispherical supporting member 124 may be an abutting surface 124a for abutting against the lower edge 123a of the mounting hole 122 or the lower edge 123a of the key 123.
Optionally, the mounting hole 122 has a centerline Z, and the support 124 is located below the centerline Z.
In some examples, at least a portion of the support 124 is disposed near the center line Z and in an orthographic projection Z' of the lower hole wall 122a of the mounting hole 122, that is, at least a portion of the support 124 is disposed near a middle portion of the lower hole wall 122a of the mounting hole 122, so that a predetermined mounting gap T can be provided between the left and right sides of the key 123 and the lower hole wall 122a of the mounting hole 122. For example, at least a portion of the support 124 may be disposed in the middle of the lower hole wall 122a of the mounting hole 122. When the support member 124 is one, the support member 124 may be disposed at the middle of the lower hole wall 122a of the mounting hole 122. When the supporting member 124 is plural, at least one supporting member 124 is disposed at the middle of the lower hole wall 122a of the mounting hole 122.
In some examples, the supporting members 124 are multiple, at least two supporting members 124 are symmetrically disposed on two sides of the central line Z, that is, at least two supporting members 124 are symmetrically distributed on two sides of an orthographic projection Z' of the central line on the lower hole wall 122a of the installation hole 122, so that a predetermined installation gap T can be provided between the left and right sides of the key 123 and the lower hole wall 122a of the installation hole 122.
Of course, the distribution of the supporting members 124 is not limited thereto. For example, a plurality of supporting members 124 may be disposed along the pressing direction of the key 123, i.e., the front-rear direction of the washing machine 1, and the supporting members 124 are spaced apart from each other to improve the supporting reliability of the key 123.
Alternatively, the mounting hole 122 has a front end facing the user and a rear end opposite to the front end, and the support 124 is disposed near the rear end of the mounting hole 122 so that the support 124 is always located at the rear side of the front end surface of the key 123.
Illustratively, the key 123 has a first preset position that is released and a second preset position that is pressed, the second preset position being located behind the first preset position; both the key 123 and the support 124 have front end faces; when the key 123 is located at the second preset position, the front end surface of the support member 124 is flush with the front end surface of the key 123, or the front end surface of the support member 124 is located at the rear side of the front end surface of the key 123; thereby, the visual effect of the main control panel assembly 12 is improved. Wherein, the supporting member 124 may extend backward to be connected with the rear hole wall of the mounting hole 122, so as to improve the supporting reliability thereof.
Optionally, the main control board 121 is provided with a plurality of mounting holes 122 for mounting the keys 123, and each mounting hole 122 is provided with a supporting member 124, so that a corresponding mounting gap T is formed between the lower edge 123a of each key 123 and the lower hole wall 122a of the corresponding mounting hole 122, thereby improving the pressing sensitivity of each key 123.
In addition, the parts of the embodiment that are not described in the description of the washing machine 1 may adopt conventional arrangements in the art, and the description of the embodiment is omitted here.
The present embodiment further provides a main control panel assembly 12, and the structure, function and implementation process of the main control panel assembly 12 may be the same as or similar to the main control panel assembly 12 in the foregoing embodiments, and are not described herein again.
It should be noted that: the main control board assembly 12 of the present embodiment is not only suitable for the washing machine 1, but also suitable for other terminal devices provided with the main control board assembly 12.
