Abstract

The utility model relates to an electric cooker with simple production process and high thermal efficiency, which comprises a shell, an inner container, a temperature controller and an electric heating plate, wherein the electric heating plate is internally provided with a heating wire and is characterized in that the outer edge of the electric heating plate extends upwards along the outer surface of the inner container to form a semi-surrounding shape; the contact part of the inner container and the outer edge of the electric heating plate is a large circular arc.

Description

rice cooker

technical field

The utility model relates to an electric rice cooker, in particular to an arc-shaped electric heating plate of the electric rice cooker.

Background technique

Existing electric rice cooker comprises shell, liner, thermostat and electric heating plate, and wherein inner container bottom contacts with electric heating plate side (as shown in Figure 1), and wherein electric heating plate 12 upper sides are convex arcs and liner. The bottom of 11 cooperates. When in use, the heating wire 13 in the electric heating plate heats up and transfers the heat to the inner pot through the side of the electric heating plate; Easy to deform.

Contents of the invention

The purpose of the utility model is to provide an electric rice cooker with simple production process and high thermal efficiency in order to solve the problems of small contact area between the liner and the electric heating plate and low thermal efficiency in the existing electric rice cooker.

Technical solutions:

The purpose of this utility model is achieved as follows: an electric rice cooker, including a shell, an inner tank, a temperature controller and an electric heating plate, wherein an electric heating wire is arranged in the electric heating plate, and it is characterized in that the outer edge of the electric heating plate extends upward along the outer surface of the inner tank It is semi-enclosed; the contact between the inner tank and the outer edge of the electric heating plate is a large arc.

Beneficial effect:

Due to the adoption of the technical solution described in the utility model, the contact between the inner container and the outer edge of the electric heating plate is a large arc, and the thickness of the inner container can reach 1.8 mm, which is 1 mm thicker than the existing electric rice cooker inner container, so it is not easily deformed. The life of the rice cooker is extended, the bottom of the inner pot is semi-enclosed with the electric heating plate, and the contact is tight, which reduces the loss, the inner pot is heated more evenly, and the thermal efficiency is improved; moreover, the bottom of the inner pot is in a large arc shape, and its production process is simpler.
