[0027] Reference to“an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase“in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily all referring to a common embodiment, or an embodiment that is independent of other embodiments. Those skilled in the art will recognize that features described in one embodiment can be combined with features described in other embodiments.

[0028] In order to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings.

[0029] With reference to Figures 1 to 5 The first embodiment of the present application provides a furnace door assembly for a cooking appliance, which comprises: a furnace door shell 100, a centrifugal fan 200, a control panel 300; the furnace door shell 100 is internally provided with a first cavity 130, the furnace door shell 100 is provided with a main air inlet hole 140 and a main air outlet hole 150 which are communicated with the first cavity 130, the centrifugal fan 200 and the control panel 300 are both fixed in the first cavity 130, and the centrifugal fan 200 is used for sequentially blowing the external gas sucked from the main air inlet hole 140 to flow through the first cavity 130 and the main air outlet hole 150, and then discharging the gas from the main air outlet hole 150.

[0030] Specifically, the furnace door shell 100 comprises a first furnace door shell 110 and a second furnace door shell 120. The first furnace door shell 110 and the second furnace door shell 120 enclose the first cavity 130. The first furnace door shell 110 is provided with a button hole 160 for penetrating a functional button 700, and the control panel 300 is connected to control the functional button 700, as shown in Figure 2 and Figure 3 .

[0031] In the embodiment, the external cold gas sequentially flows through the main air inlet hole 140, the centrifugal fan 200, the first cavity 130 and the main air outlet hole 150, and then is discharged from the main air outlet hole 150. Since the control panel 300 is arranged in the first cavity 130, the working environment temperature of the control panel 300 is reduced. The centrifugal fan 200 is used for increasing the flow force of the cold air gas input from the main air inlet hole 140 before discharging and sending the cold air gas to the first cavity 130, so that the external input cold gas quickly and in large quantities enters the first cavity 130 and is discharged from the main air outlet hole 150, so as to quickly reduce the working environment temperature of the control panel 300 and further improve the reliability of the control panel 300.

[0032] In some embodiments, the oven door assembly for the cooking appliance is further provided with a control support 800, and the control panel 300 is fixed to the inner side wall of the first oven door shell 110 through the control support 800, or the control panel 300 is fixed to the inner side wall of the second oven door shell 120 through the control support 800.

The air deflector 400 is used for guiding the gas blown by the centrifugal fan 200 to flow through the first cavity 130 at the outer periphery of the control panel 300 in sequence and then flow to the main air outlet hole 150.

[0035] In this embodiment, the air discharged by the centrifugal fan 200 flows directly to the air deflector 400 after flowing through the outer periphery of the control panel 300, and due to the air guiding effect of the air deflector 400, the flowing gas flows to the main air outlet hole 150 and is discharged through the main air outlet hole 150.

[0036] With reference to Figures 1 to 3 , the air deflector 400 is in the shape of a circular arc.

[0037] In this embodiment, the first panel surface of the air deflector 400 is a concave surface, which further enhances the air guiding effect of the air deflector 400 and improves the smoothness of gas discharge and the heat dissipation effect.

[0038] With reference to Figures 1 to 3 , the main air inlet hole 140 and the main air outlet hole 150 are located on the bottom cavity wall of the first cavity 130 and penetrate through the bottom wall of the oven door shell 100.
