[0055] Optionally, a second limiting portion 212 extending upward is provided on the inner side wall of the top of the bottom shell 21, and the second limiting portion 212 is attached to the inner side wall of the upper cover 22. By providing the second limiting portion 212, further limiting of the bottom shell 21 and the upper cover 22 during installation is achieved.

[0056] Optionally, an elastic buckle 232 is further provided on the outer peripheral side of the bottom shell 21 , and a mounting portion 231 is further provided on the lower side of the bottom shell 21 .

[0057] On the other hand, the utility model provides a household appliance, comprising an outer door 1 and the above-mentioned status display device of the household appliance, wherein the status display control device of the household appliance is installed on the inner side of the outer door 1 and is communicatively connected with the control panel of the household appliance.

[0058] Optionally, the outer door 1 is provided with an inwardly recessed profile 10, and a second clip hole 100 corresponding to the elastic clip 232 is opened on the profile 10. The elastic clip 232 is inserted into the second clip hole 100, and the front end surface of the elastic clip 232 is set lower than the outer side surface of the outer door 1 or is set flush with the outer side surface of the outer door 1 to avoid the elastic clip 232 protruding from the outer side surface of the outer door 1, thereby achieving an aesthetic effect. In addition, by setting the profile 10, it can also play a role in strengthening the strength of the outer door 1 at that location, so that the status display device of the household appliance can be stably installed on the outer door 1.

[0059] Optionally, a third limiting portion is also provided on the outer peripheral side of the bottom shell 21. When the elastic clip 232 is inserted into the second clip hole 100 and is in place, the front side surface of the third limiting portion abuts against the inner side surface of the outer door 1, thereby realizing the installation positioning between the elastic clip block and the second clip 223.

[0060] Optionally, a flange 11 extending inward is provided on the lower side of the outer door 1, and an upwardly recessed mounting boss 12 and a light outlet corresponding to the light outlet hole 2101 are provided in the flange 11.
