Description

Electric steam box

Technical Field

The invention relates to the field of cooking devices, in particular to an electric steam box.

Background

An electric steam box is a cooking device for cooking food by using steam, generally comprising an inner container for placing the food to be cooked, and an external steam generator or an internal steam generator generates steam to be filled into the inner container, thereby realizing the steaming and heating of the food. Such as the structure of an electric steamer disclosed in the Chinese patent with the application number of CN201810940389.6 (with the publication number of CN110833311A), the Chinese patent with the application number of CN201721384366.9 (with the publication number of CN208625331U) and the like.

When an existing electric steam box is used for cooking, food is generally placed on a steaming plate, and then the steaming plate with the food is placed in an inner container of the electric steam box. For example, a Chinese utility model patent ZL201821962489.0 (No. CN209528916U) discloses a steaming tray, a steaming tool and a steaming box, wherein the steaming tray comprises a steaming tray main body, and a plurality of steaming holes are arranged on the steaming tray main body; at least one boss is arranged on the steaming tray main body, and the upper surface of the boss is higher than the upper surface of the steaming hole. When food or tableware such as plates and the like containing food is placed on the steaming tray, the food or the tableware is placed on the lug boss, the steaming hole cannot be blocked, and the heating efficiency is higher.

The cooking mode using the steaming tray has the following problems: (1) by adopting the cooking steaming tool with the steaming plate completely opened, the utilization rate of steam is lower when a small amount of food is cooked; (2) when different foods are cooked together, the foods are easily tainted with each other because the foods are simultaneously placed in the inner container; (3) adopt open steaming tray completely as culinary art steaming tool, the culinary art finishes to have more steam to rush out when opening the door, has the risk of scalding the user.
