Description

This application claims priority to Chinese Patent Application No. 202310795422.1 filed with the China National Intellectual Property Administration on June 30, 2023 and entitled "COOKING CHAMBER ASSEMBLY AND COOKING APPLIANCE", the entire contents of which are incorporated herein by reference. FIELD The present application relates to the field of household electrical appliances, and more particularly, to a cooking chamber assembly and a cooking appliance. BACKGROUND In the prior art, for a cooking appliance with an air frying function, an air frying assembly typically occupies a relatively large installation space, which results in a large size of the cooking appliance and a non-compact product structure. SUMMARY The present application aims to solve at least one of the problems existing in the prior art or related art. Thus, a first purpose of the present application is to provide a cooking chamber assembly. A second purpose of the present application is to provide a cooking appliance. To achieve at least one of the above purposes, according to the first aspect of the present application, a cooking chamber assembly is provided, comprising: a main body, comprising a cooking cavity; an air frying assembly, configured to blow hot air into the cooking cavity, wherein a wall surface of the main body is provided with a plurality of accommodating recesses, at least part of the accommodating recesses are recessed in a direction towards the cooking cavity, and at least part of the air frying assembly is disposed in the accommodating recesses recessed towards the cooking cavity. The cooking chamber assembly provided in the present application can be applied to a cooking appliance. The cooking chamber assembly comprises the main body, and the main body comprises the cooking cavity for accommodating food ingredients. When the cooking appliance is in operation, the cooking appliance cooks the food ingredients placed inside the cooking cavity. Furthermore, the cooking chamber assembly comprises the air frying assembly, and the air frying assembly can cook the food ingredients in the cooking cavity in an air frying manner. In some embodiments, in the case that the air frying assembly is in operation, it can blow hot air into the cooking cavity, and the food ingredients in the cooking cavity can be heated by the hot air to achieve a cooking effect of air frying. The air frying assembly is composed of a plurality of components, resulting in a certain thickness of the air frying assembly. To reduce the height of the air frying assembly projecting from the outer wall of the main body, the present application provides a plurality of accommodating recesses in the wall surfaces of the main body. By arranging at least part of the air frying assembly in the accommodating recesses, the height of the air frying assembly projecting from the wall surfaces of the main body can be reduced. In some embodiments, the wall surfaces of the main body are provided with a plurality of accommodating recesses, and at least one of the accommodating recesses are recessed towards the cooking cavity, that is, the recess walls of the accommodating recesses extend into the cooking cavity, and at least part of the air frying assembly is disposed in the accommodating recesses recessed towards the cooking cavity. In this way, by allowing the air frying assembly to occupy part of the space of the cooking cavity, the height of the air frying assembly projecting from the wall surfaces of the main body can be reduced, to reduce the distance between a housing of the cooking appliance and the wall surfaces of the cooking chamber assembly, then enabling the cooking appliance to have a narrow bezel and reducing the size of the cooking appliance. The bezel of the cooking appliance to which the cooking chamber assembly is applied in the present application can be narrowed to 30mm. Furthermore, the various components of the air frying assembly employ a nested configuration, and thus the height of the air frying assembly is reduced. By using the structure of the nested configuration, the height of the air frying assembly is reduced to 50 mm, further decreasing the size of the cooking appliance to which the cooking chamber assembly is applied. A wall surface of the main body is provided with the accommodating recesses recessed in a direction towards the cooking cavity, and at least part of the air frying assembly is disposed in the accommodating recesses, and the height of the air frying assembly projecting from the wall surfaces of the main body can be decreased, to decrease the distance between the housing of a cooking appliance and the wall surfaces of the cooking chamber assembly, enabling the cooking appliance to have a narrow bezel, reducing the size of the cooking appliance, making the structure of the cooking appliance more compact, and facilitating miniaturization design of the product. The above cooking chamber assembly according to the present application
