In other embodiments, the display panel 3 is a touch screen panel which displays an operation display pattern for adjusting a cooking state, such as a power adjustment pattern, a function selection pattern, etc., in addition to the cooking state, such as cooking power, cooking time, cooking temperature, etc., and adjusts the cooking state of the home appliance by touching the operation display pattern.

With continued reference to fig. 1, in some optional embodiments, the household appliance may be an electric cooker, the electric cooker further includes a cooker body 5, a heating structure and the like are disposed on the housing 2, and the cooker body 5 and the housing 2 are connected to form an accommodating space for accommodating an inner container of the electric cooker.

In one possible implementation manner, the number of the digital display parts is consistent with the number of the display pieces, namely, the number of the digital display parts corresponds to the number of the display pieces one to one, and the digital display parts are enabled to display corresponding digits by controlling the drive circuit so as to control the digits displayed by the display pieces, and further display corresponding working information of the household appliance, so that a user can know the current working state of the household appliance more clearly and conveniently.

In one possible implementation manner, the number of the digital display parts is greater than that of the display parts, namely, a part of the digital display parts and the display parts are covered on the display parts in a one-to-one correspondence manner, and the digit displayed by the display parts is controlled by controlling the driving circuit so that the digital display parts display corresponding digits and further display corresponding working information of the household appliance, so that a user can know the current working state of the household appliance more clearly and conveniently; the other part of the digital display part does not have a corresponding display part, when the display content needs to be increased, namely the digit of the display part on the circuit board 111 is increased, so that the digital display part corresponds to the newly increased display part, the display digit of the household appliance can be increased, and the working information of the household appliance can be more clearly reflected.

In one possible implementation, the display is a plurality of LED lamps mounted on the circuit board 111. For a seven-segment nixie tube, the display may include seven LED lights, forming an "8" shape. For an eight-segment nixie tube, the display includes eight LED lights, seven of which make up an "8" shape, the other being a decimal point. The display part is formed by mounting a plurality of LED lamps on the circuit board 111, so that the display part is simple and quick to mount and is beneficial to improving the assembly efficiency.
