[0098] See also Figure 11 As shown, in some embodiments, a resilient arm 282 may be provided on the back side of the display module 28. The resilient arm 282 may extend rearwardly and obliquely from the back side of the display module 28. When the door panel 21 is mounted on the front side of the door frame 22, the back side of the door panel 21 abuts against the light-emitting surface 281, so that the resilient arm 282 abuts against the bottom wall of the mounting cavity 271. This allows the display module 28 to be mounted within the mounting cavity 271 and ensures a close fit between the door panel 21 and the light-emitting surface 281, thereby improving the display effect on the door panel 21.

[0099] In some embodiments, the elastic arm 282 can extend obliquely upward and backward from the back side of the display module 28. When the door panel 21 is installed on the front side of the door frame 22, the rear end of the elastic arm 282 abuts against the bottom wall of the installation cavity 271.

[0100] It should be noted that in some other embodiments, the elastic arm 282 can be arranged to extend obliquely downward and rearward from the back side of the display module 28. When the door panel 21 is installed on the front side of the door frame 22, the rear end of the elastic arm 282 abuts against the bottom wall of the installation cavity 271.

[0101] It should also be noted that, in other embodiments, the elastic arm 282 may be arranged to extend obliquely from the back side of the display module 28 toward the left rear, or toward other directions.

[0102] In some embodiments, when the display module 28 is installed in the installation cavity 271 , the bottom surface of the display module 28 abuts against the lower side wall of the installation cavity 271 , thereby positioning the display module 28 in the installation cavity 271 .

[0103] In some embodiments, multiple elastic arms 282 may be provided. These multiple elastic arms 282 may be spaced apart and arranged around the rear sidewall of the display module 28. When the door panel 21 is mounted on the front side of the door frame 22, the rear ends of the multiple elastic arms 282 can simultaneously abut against the bottom wall of the mounting cavity 271. The multiple elastic arms 282 ensure uniform force on the display module 28, allowing the luminous surface 281 of the display module 28 to more smoothly align with the door panel 21.

[0104] See also Figure 11 As shown, in some embodiments, an abutment portion 2711 may be provided on the back wall of the mounting cavity 271. When the display module 28 is installed in the mounting cavity 271, the rear end of the elastic arm 282 can be arranged front-to-back with the abutment portion 2711. Furthermore, when the door panel 21 is installed on the front side of the door frame 22, the rear end of the elastic arm 282 can abut against the abutment portion 2711. By abutting against the abutment portion 2711 and the elastic arm 282, the elastic arm 282 can be compressed when the door panel 21 is installed on the front side of the door frame 22, thereby ensuring that the light-emitting surface 281 and the door panel 21 are in close contact.

[0105] See also Figure 11 As shown, in some embodiments, a positioning arm 283 may be provided on the side wall of the display module 28. The positioning arm 283 may extend obliquely outward from the side wall of the display module 28. When the display module 28 is installed in the mounting cavity 271, the positioning arm 283 can abut against one side wall of the mounting cavity 271, so that the side wall of the display module 28 away from the positioning arm 283 abuts against the other opposite side wall of the mounting cavity 271, thereby retaining the display module 28 in the mounting cavity 271 and improving the installation stability of the display module 28 in the mounting cavity 271.

[0106] See also Figure 11 As shown, in some embodiments, a positioning portion 2712 may be provided inwardly on the sidewall of the mounting cavity 271. The positioning portion 2712 may be provided on the sidewall of the mounting cavity 271 opposite the positioning arm 283. When the display module 28 is installed in the mounting cavity 271, the positioning arm 283 can abut against the positioning portion 2712. The abutment between the positioning portion 2712 and the positioning arm 283 can position the display module 28 in the mounting cavity 271, thereby improving the accuracy of the installation of the display module 28.

[0107] In some embodiments, when the display module 28 is installed in the installation cavity 271 , the positioning arm 283 can abut against the positioning portion 2712 , and the elastic arm 282 and the abutting portion 2711 can be arranged front to back.

[0108] In some embodiments, multiple positioning arms 283 may be provided. Multiple positioning arms 283 may be spaced apart vertically on the sidewalls of the display module 28. When the display module 28 is installed in the mounting cavity 271, the outer ends of the multiple positioning arms 283 can simultaneously abut against the sidewalls of the mounting cavity 271. The multiple positioning arms 283 ensure uniform vertical force on the display module 28.

[0109] See also Figures 2 to 12 As shown, in some embodiments, a first hook 213 may be provided on the back side of the door panel 21. The first hook 213 may be extended from the back side of the door panel 21, bent backward and then downward. A first engaging groove 2713 may be defined within the mounting cavity 271. When the door panel 21 is mounted on the front side of the door frame 22, the first hook 213 can extend through the mounting opening 2212 and engage within the first engaging groove 2713. Therefore, the door panel 21 can be secured to the mounting cover 27 via the first hook 213, thereby enabling the door panel 21 to be urgently attached to the luminous surface 281, thereby improving the display effect on the door panel 21.

[0110] It should be noted that in some other embodiments, there may be multiple first hooks 213. A corresponding number of first engaging grooves 2713 may be provided. By having multiple first hooks 213 engage with multiple first engaging grooves 2713 simultaneously, the connection stability between the door panel 21 and the mounting cover 27 can be improved.

[0112] See also Figures 13 to 15As shown, in some embodiments, a second fixing plate 214 may be provided on the back side of the door panel 21. The second fixing plate 214 may be provided at the bottom of the door panel 21. A fixing groove 241 is provided on the front side wall of the lower end cover 24. When the door panel 21 is mounted on the front side of the door frame 22, the second fixing plate 214 on the door panel 21 can extend into the fixing groove 241. The door panel 21 is then moved downward relative to the door frame 22 so that the second hook 211 is engaged with the second engaging groove 261. At this time, the lower end surface of the second fixing plate 214 can abut against the lower side wall of the fixing groove 241, thereby achieving a fixed connection between the second fixing plate 214 and the fixing groove 241.

[0113] In some embodiments, a third fixing hole 2141 is defined in the second fixing plate 214. A fourth fixing hole 242 is defined in the lower sidewall of the fixing slot 241. When the lower end surface of the second fixing plate 214 is in contact with the lower sidewall of the fixing slot 241, the third fixing hole 2141 can be arranged directly opposite the fourth fixing hole 242. Screws can then be used to secure the third fixing hole 2141 and the fourth fixing hole 242, thereby securing the second fixing plate 214 within the fixing slot 241. This secures the door panel 21 to the door frame 22, thereby limiting the upward freedom of the door panel 21 within the door frame 22.
