Description

Technical Field

[0001] The utility model relates to the field of steam ovens, and particularly refers to a heating structure for the inner cavity of a steam oven. Background Art

[0002] For the consideration of space utilization rate and purchase cost, modern families mostly use a steam oven with both steaming and baking functions for kitchen cooking. According to requirements, the steam oven can select the functions of a steamer or an oven. When the steamer function is selected, water is evaporated by an evaporation pan arranged at the bottom of the inner cavity to generate steam; when the oven function is selected, heating tubes are arranged at the top of the inner cavity and cooperate with a circulation fan on one side to perform heat circulation.

[0003] However, the above configuration will cause the food to be heated only unidirectionally when using the oven function, and manual turning is required in the middle of cooking for some foods; although there are automatic turning drums in some types of ovens, this structure is not applicable to steam ovens.

[0004] Therefore, the inventor of the present case conducts further research and develops a heating structure for the inner cavity of a steam oven, and this case is thus generated. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a heating structure for the inner cavity of a steam oven, which can make the heating more uniform when the steam oven uses the oven function.

[0006] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A heating structure for the inner cavity of a steam oven, comprising

[0008] an inner cavity and four groups of heating tubes, and the heating tubes are respectively arranged on the upper, lower, left and right sides of the inner cavity; wherein, circulation fans are arranged on the left and right sides of the inner cavity, and an evaporation pan is arranged at the bottom of the inner cavity; the heating tubes at the bottom of the inner cavity are arranged in a ring around the evaporation pan, the heating tubes on both sides of the inner cavity are arranged in a ring around the circulation fans, and the heating tubes at the top of the inner cavity are distributed in a continuous serpentine shape.

[0009] According to the internal structure of the steam oven, the distribution of the heating tubes required for the oven function is redesigned to make it more in line with the heat expansion requirement, so that the food can be heated more evenly during baking.

[0010] Further, the heating tubes on the upper, left and right sides of the inner cavity are arranged inside the inner cavity, and the heating tubes at the bottom of the inner cavity are arranged outside the inner cavity.

[0011] Further, a bracket is arranged on the upper surface of the upper heating tube of the inner cavity, and the upper heating tube is fixed to the top of the inner cavity through the bracket.

[0012] Further, there are shelves on both sides of the inner liner. There are several raised tracks on the shelves. At the same time, through holes matching the heating pipes on both sides are also provided on the shelves.

[0013] Generally, trays and the like need to be provided inside the steam oven for holding various foods to be heated, and both sides of the tray are guided by tracks.

[0014] Further, the heating pipes at the bottom of the inner liner include an annular pipe in the middle and serpentine pipes on both sides.

[0015] Due to the presence of the evaporation pan, the heating pipes at the bottom need to be adjusted adaptively compared with the heating pipes at the top.

[0016] Further, the heating pipes at the bottom are arranged on the base, and the base is installed on the bottom of the inner liner.

[0017] After adopting the above scheme, compared with the prior art, the utility model has the following advantages:

[0018] When using the oven function in the steam oven, compared with the prior art, a more uniform heating method is provided, making the cooking of food more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
