detailed description

The principles and features of the present invention are described in the following with reference to the accompanying drawings.

First set of embodiments

As shown in FIG. 1 and FIG. 2, in the prior art, the electric cooker is composed of a casing 3, a base 4 and an outer pot 2, the outer pot 2 is disposed in the outer casing 3, and the cast aluminum heating plate 6 is installed at the bottom of the outer pot 2. It is supported by the spring 5. When the inner liner 1 is placed in the outer pot 2, the bottom of the inner liner 1 contacts and presses the cast aluminum heating plate 6, and the spring 5 supporting the cast aluminum heating plate 6 is compressed downward, and the reverse force of the spring 5 causes the cast aluminum heating plate to be heated. 6 and the bladder 1 maintain good and effective contact. When the food is heated, the cast aluminum heating plate 6 is energized and heated, and the heat is transferred to the inner tank 1 by heat conduction. However, the way of heat conduction is only to transfer heat to the bottom of the inner tank 1, and there is a disadvantage that the bottom of the inner tank and the periphery are unevenly heated, and the heating efficiency is low.

As shown in FIG. 3 and FIG. 4, the present invention relates to a radiant-heated infrared disk electric hot food processing tool, which may specifically be an electric cooker. The following description is based on the structure of an electric cooker: including a casing 3, an outer pot 2, and The inner pot 2 is disposed in the outer casing 3, and the inner tank 1 is placed in the outer pot 2, and further comprises an infrared disc 7 and an electric device electrically connected to the infrared disc 7, the upper end of the inner tank 1 is extended Out of the outer pot 2 and the outer casing 3, and extending outward to form an annular outer edge, the outer edge of the inner liner 1 is crimped onto the upper end surface of the outer casing 3, and the infrared disk 7 is disposed in the outer pot 2 In the inner bottom, the inner liner 1 is located above the infrared disk 7, and the bottom of the inner liner 1 is completely out of contact with the infrared disk 7 with a gap.

When the inner liner 1 is placed in the outer pot 2, the inner liner 1 and the infrared ray disc 7 are completely out of contact, and a gap for air convection is formed therebetween. When the food is heated, the infrared disk 11 is energized and heated, and the infrared disk 7 directly heats the inner liner 1 by means of thermal radiation (infrared radiation). As shown by the straight arrow in FIG. 4, since the infrared radiation distance is long and the area is large, the infrared disk can be made The heat absorption area of the liner 1 is sufficiently large and uniform in heating, and the heating efficiency is higher. Meanwhile, since the gap between the inner liner 1 and the infrared disk 7 exists, the infrared disk 7 also heats the air in the outer pot 2, and the air in the outer pot 2 is heated to form heat between the surface of the outer pot 2 and the surface of the inner liner 1.

In use, the inner liner 1 sometimes needs to be lifted, and the outer edge of the inner liner 1 can be used for the user to lift the inner liner 1 by hand, preferably, on the outer side of the outer outer edge of the inner liner 1, extending upwardly. The upper end of this part can also be provided with a horizontally extending annular edge, which can be better used for lifting by the user, and is more convenient to use.
