In the description of the present invention, "a first feature" or "a second feature" may include one or more of the features, and "a plurality" means two or more, and the first feature may be "on" or "under" the second feature, and may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature therebetween, and the first feature being "on", "above" and "above" the second feature may include the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature is higher in level than the second feature.

In the related art, the protective cover is fixed by a fixing bracket. For example, in some cooking appliances, several fixing brackets are provided around the heat-insulating cover of the upper cover, and then the protective cover is mounted on the fixing brackets. The fixed support is positioned at the periphery of the heat preservation cover and the periphery of the hot air fan and just positioned on the air duct of hot air circulation. The fixed bolster can destroy the smooth and easy nature of wind flow, makes the windage increase, reduces the efficiency of the inside thermal convection of cooking utensil, makes the speed of food dehydration slow down, and the culinary art time lengthens. And, the fixed bolster can change the flow direction of wind stream in the wind channel, makes the inside wind stream of cooking utensil disorderly, leads to the culinary art intracavity temperature distribution uneven, influences the culinary art effect.

Therefore, the present application provides a lid subassembly 100 of cooking utensil 200, need not to set up the fixed bolster and can realize the fixed of protective cover plate 20, and protective cover plate 20's fixed knot constructs and does not have the influence to the smooth and easy nature of wind flow in wind channel 102, it is lower to make the windage, cooking utensil 200 inside heat convection efficiency is higher, be favorable to reducing the culinary art time, and protective cover plate 20's fixed knot constructs and does not have the influence to the flow direction of wind flow, it is orderly to make cooking utensil 200 inside wind flow, be favorable to improving the homogeneity of culinary art intracavity temperature distribution, improve the culinary art effect.

The cover assembly 100 and the cooking appliance 200 of the cooking appliance 200 according to the embodiment of the present invention are described below with reference to the accompanying drawings.

Referring to fig. 1 to 3, a cover assembly 100 of a cooking appliance 200 according to an embodiment of the present invention may include: a cap body 10 and a protective cover 20.

Specifically, one side of the lid body 10 has an opening 101, the protective cover 20 is disposed on the lid body 10, an air duct 102 is defined between the protective cover 20 and the lid body 10, and hot air can flow between the air duct 102 and the cooking cavity to heat the food in the cooking cavity, for example, the food in the cooking cavity can be baked, fried, air-fried, and the like.

As shown in fig. 1 to 3, the inner circumferential wall of the cover body 10 has a mounting step 11, the mounting step 11 extends in the circumferential direction of the opening 101, and the protective cover 20 is connected to the mounting step 11. That is, the protective cover 20 is directly coupled to the cover body 10 without providing a fixing bracket in the related art, thereby reducing the number of parts. Moreover, since the air duct 102 is located between the cover body 10 and the protective cover plate 20, the connecting structure between the protective cover plate 20 and the installation step 11 is not located in the air duct 102, thereby preventing the hot air convection from being blocked, ensuring the high efficiency of the hot air convection, and being beneficial to reducing the cooking time of food materials. Moreover, the fixed structure of the protective cover plate 20 does not interfere the flow direction of the air flow in the air duct 102, and the hot air can flow in the air duct 102 and between the air duct 102 and the cooking cavity in order according to the expected flow path, so that the uniformity of the temperature distribution in the cooking cavity is improved, and the fast cooking and the good cooking effect are ensured.
