Example Embodiment

[0026] Aiming at the problem that the existing electric heating fabric cannot obtain a uniform temperature when it is energized, the present invention proposes an electric heating element, which can achieve uniform electric heating performance in a plane or three-dimensional direction; the electric heating element of the present invention is light in weight , Soft, uniform heating, avoiding the local overheating problem that limits the application range of existing fabrics. The electric heating element includes an electric heating fabric, which includes conductive yarns that can conduct low-voltage current; in addition, the electric heating fabric also includes resistance yarns, which are used to block the passage of current to generate heat and have a certain degree of The insulation effect. The electric heating fabric can be a textile composite material or a layered fabric, which is woven from conductive yarns and resistive yarns. Under a certain DC voltage, evenly distribut...

Abstract

The invention provides an electric heating element and a heating method thereof. The electric heating element includes an electric heating fabric which includes an electric heating yarn unit. The electric heating yarn unit includes a conductive yarn and a resistor yarn. The conductive yarn and the resistor yarn are connected in parallel. The electric heating element also includes a pair of electrodes which respectively penetrate the front side and back side of the electric heating fabric and provide voltage between the front side and the back side of the electric heating fabric. According to the invention, the electric heating element has an electric heating fabric which is composed of the conductive yarn and the resistor yarn which are woven together, and provides a voltage between the front side and back side of the electric heating fabric. According to the invention, the electric heating element heats evenly, and can be applied to the fields of orthotics and the like.

Description

technical field [0001] The invention relates to an electric heating element and a heating method thereof. Background technique [0002] With the development of flexible heating technology, various electric heating fabrics that improve the heating capacity and heating stability of electric heating fabrics have been developed. [0003] US Patent No. 5,484,983 proposes an electric heating fabric with a basic mesh structure. Among others, such electrically heated fabrics are used for the production of non-planar fabric laminates or textile composites. A pair of electrodes are respectively arranged on both sides of the conductive electric heating fabric to provide electric current to the electric heating fabric. In this way, the conductive electric heating fabric can generate heat under the action of electric current. At present, this conductive electric heating fabric can play a heating role in many fields, such as in the field of wearable heating equipment, medical field, ho...
