Abstract

The invention relates to an electric heater comprising a shell, a heating element and a drive piece. An air duct is arranged in the shell. The shell is provided with an air opening enabling the air dust to communicate with the outside. The heating element is arranged in the air dust. The heating element is used for conducting radiative heat transfer with the outside and convection heat transfer through the air opening. The drive piece is used for driving the heating element to rotate in the air duct so as to disturb a flow field in the air duct. According to the electric heater, the drive piece can drive the heating element to rotate in the air duct so as to disturb the flow field in the air duct, the heating element amounts to a rotating blade, so that the convection function between theair in the air duct and the external air can be enhanced at the moment, and the electric heater has a good convection effect compared with the prior art.

Description

technical field

[0001] The invention relates to the technical field of heating equipment, in particular to an electric heater. Background technique

[0002] In order to improve the environment and reduce environmental pollution caused by coal-fired heating, more and more cities are vigorously promoting the "coal-to-electricity" project and encouraging the use of electric heating technology for heating.

[0003] Electric heaters are generally based on natural convection heat transfer and radiation heat transfer. Natural convection heat transfer uses the density difference between hot and cold air as power to drive indoor air circulation, thereby adjusting the indoor temperature. The heat of radiation heat transfer is easily absorbed by the human body and the body. Absorbed by the clothes worn, the human body has a good heating effect and is highly efficient and energy-saving.

[0004] Traditional electric heaters that can conduct both convective and radiative heat transfer h...

Embodiment Construction

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0034] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...
