In the second way, the display device is arranged on the handle of the door element, for example, the Chinese utility model patent "A steam oven with a synthetic handle" with patent number ZL202123200623.8 (authorization announcement number CN217185640U). In the third way, the display device is arranged inside the door element, for example, the Chinese utility model patent "An air oven with temperature display" with patent number ZL202220182110.4 (authorization announcement number CN217161840U).
[0003] However, the above-mentioned display device configurations have the following problems: In the first configuration, the display device alone occupies part of the front area of the cooking device, limiting the size of the cooking space. In the second configuration, the configuration of the display device limits the structural form of the handle, and the handle also limits the size of the display device, affecting the display effect. In the third configuration, since the internal temperature of the door element is relatively high (especially in cooking devices with baking functions such as ovens), the service life of the display device is affected, and generally a heat dissipation element (e.g., a heat dissipation fan) is required to assist in reducing the internal temperature of the door element, which increases the cost.
