Electric heating warm box

Abstract

The invention discloses an electric heating warm box. A box body, a plurality of ceramic insulating columns, a plurality of heating resistance wires, a honeycomb plate, a carbon fiber wire heating layer, a gauze element and a temperature adjustor are included; the box body is provided with a cavity with an opening in the top; the ceramic insulating columns are fixed to the bottom of the cavity ofthe box body; the heating resistance wires are connected in series; one end of each heating resistance wire is connected with one corresponding insulating column; and the other end of each heating resistance wire is connected with the other corresponding insulating column. According to the electric heating warm box, the temperature adjustor is adopted for controlling high-power heating of the heating resistance wires and low-power heating and heat preserving of the carbon fiber wire heating layer, and the functions are diverse; and under low-power heating and heat preserving, the electricity consumption amount is low. The electric heating warm box is provided with the honeycomb plate, while it is guaranteed that hot air generated when the heating resistance wires work ascend, foreign matter can be blocked, it is avoided that the foreign matter passes through the gauze element and is in contact with the heating resistance wires for combustion, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of heating boxes, in particular to an electric heating box. Background technique [0002] Heating box is a kind of commonly used heating equipment, which is divided into industrial heating box and domestic heating box. Industrial heating box is widely used in various industrial heating and drying, and is often used as heating equipment in production lines or large machines , Heating boxes for daily use are widely used in the heating of various food and beverages and other daily necessities. Even in recent years, heating boxes have been used as auxiliary heating equipment when the temperature is low in winter, and the feet and lower limbs of the human body can be placed on them for heating. keep warm. [0003] The current electric heating box is mainly composed of a shell, an electric heating wire and an article carrying plate, and its function is relatively single, and it is generally used for heating and k...
