Embedded type electric heat fan for heating disc

Abstract

The invention relates to the field of electric heat fan technology, in particular to an embedded type electric heat fan for a heating disc. The electric heat fan comprises a metal liner and a housing. The metal liner is cooperatively arranged in the housing. An aluminum alloy base disc is arranged at the bottom of the metal liner. An electric heating disc and a temperature measuring bar are embedded in the aluminum alloy base disc. Multiple heating pipes and heat conducting fins are arranged in the electric heating disc. The heating pipes are arranged corresponding to the heat conducting fins. A temperature controller is arranged on the housing. A temperature adjusting device is arranged in the temperature controller. The temperature measuring rod is electrically connected with the temperature adjusting device. The heating pipes are electrically connected with the temperature controller. A temperature control switch knob and a power socket are arranged on the temperature controller. According to the invention, by embedding the electric heating disc in the aluminum alloy base disc and embedding the heating pipes in the heat conducting fins, the heat is upwards transmitted to the aluminum base disc so as to uniformly heat food; and the temperature controller and the temperature measuring bar are capable of precisely detecting temperature of the aluminum alloy base disc and when the temperature of the aluminum base disc exceeds a certain temperature, power can be timely broken off, so the electric heat fan can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of electric heating pans, in particular to an electric heating pan for an embedded heating plate. Background technique [0002] As a kitchen appliance that uses electric heat to cook food, the electric hot pot has high thermal efficiency, long service life and complete functions. The electric hot pot can not only cook the food, but also keep it warm. It is clean and hygienic when used. It is an indispensable appliance for the modernization of housework. one. The heating device under the inner pot of the traditional electric heating pot is a heating plate (or other heating elements). The heating plate is in contact with the bottom wall of the inner pot.

Problems solved by technology

The heating device under the inner pot of the traditional electric heating pot is a heating plate (or other heating elements). The heating plate is in contact with the bottom wall of the inner pot. The heating coil will transfer part of the heat directly to the bottom wall of the inner pot, resulting in uneven temperature distribution of the bottom wall of the inner pot. Therefore, the heat from the bottom wall of the inner pot is quickly transferred to the side wall of the outer pot, so that the temperature of the side wall of the outer pot is also very high.

During the cooking process of the electric heating pot, the entire outer pot will radiate heat outward, and this part of the heat cannot be effectively used, resulting in the waste of this part of the radiated heat, resulting in a reduction in energy efficiency
