Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, specifically to an intelligent steam oven inner cavity structure. Background Technology

[0002] The inner cavity of a steam oven is its core component, serving as a sealed space to hold food and provide heating or steam cooking. Traditional steam oven inner cavities are typically welded from stainless steel sheets, housing heating elements (such as heating tubes) and a fan to achieve hot air circulation or steam cooking. Smart steam ovens integrate steaming and baking functions, offering steaming, baking, and mixed steam-baking modes. In the mixed mode, humidity is also adjustable, catering to different ingredients and cooking methods. The structural design of the inner cavity directly affects the steam oven's thermal efficiency, temperature uniformity, and ease of cleaning.

[0003] Existing commercial steam ovens have a simple inner cavity structure with shallow, shallow side panels, lacking sufficient strength. Under high temperatures, the stainless steel sheet metal is prone to deformation, causing poor hot air circulation and affecting the evenness of cooking. Furthermore, the interior of existing inner cavities easily forms hard-to-clean corners, posing hygiene and safety risks with long-term use. Therefore, there is an urgent need for a steam oven inner cavity structure that is more stable, has more efficient hot air circulation, and is easier to clean. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent steam oven inner cavity structure that enhances structural strength and improves cleaning convenience by optimizing the design of the stretching bosses in the inner cavity.

The inner cavity top plate, inner cavity bottom plate, inner cavity right rear side plate, and inner cavity left side plate form the inner cavity cavity, and the air duct baffle divides the inner cavity cavity into a heating zone and a cooking zone. The heating zone is equipped with an electric heating tube and a centrifugal fan. A fan is connected to one side of the centrifugal fan located on the outside of the inner cavity cavity. A tray rack is provided in the cooking zone.

[0006] Both the top and bottom plates of the inner liner are stretched with inner liner protrusions adapted to the volume size of the inner liner, and a steaming and baking protrusion is stretched in the cooking area based on the inner liner protrusions.
