BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0011] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0012] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0013] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0014] like Figure 1As shown, the high-efficiency electric rice steaming box includes a box body 1, a box door 2 is installed on the box body 1, a rice steaming chamber 3 is provided inside the box body 1, a number of rice steaming trays 4 are provided in the rice steaming chamber 3, both sides of the rice steaming trays 4 are respectively placed on support plates 5, and the support plates 5 are fixedly connected to the inner wall of the box body 1, and an air collecting hood 6 is provided at the upper end of the rice steaming chamber 3, a pressure relief pipe 7 is connected to the air collecting hood 6, the upper end of the pressure relief pipe 7 is extended out of the box body 1, and a pressure relief valve 8 is installed on the pressure relief pipe 7. An air distribution chamber 9 is provided at the lower end of the rice steaming chamber 3, a steam pipe 10 is fixedly connected to the box body 1, one end of the steam pipe 10 is connected to the steam engine, and the other end is connected to the air distribution chamber 9, a steam circulation pipe 11 is provided inside the box body 1, the upper end of the steam circulation pipe 11 is connected to the air collecting hood 6, and the lower end of the steam circulation pipe 11 is connected to the air distribution chamber 9, a circulating fan 12 is installed on the steam circulation pipe 11, and an electric heating coil 13 is provided between the air distribution chamber 9 and the rice steaming chamber 3.

[0015] Furthermore, an air distribution plate 14 is provided in the air distribution chamber 9. The air distribution plate 14 is provided with a plurality of air holes evenly spaced apart.
