Description
Electric heater for heating The present invention relates to an electric heater for heating, and more specifically, to an electric heater for heating that heats surrounding air flowing through a heating element by heating it through resistance, diffuses the heat into a wide space, and circulates it as far and evenly as possible to improve energy efficiency. Generally, radiant electric heaters operate by directly transferring heat in a specific direction, while convection electric heaters operate by releasing heat generated internally through air convection. Recently, so-called highlight electric heaters are gaining popularity because they produce no odor, smoke, or noise, have a longer lifespan compared to ceramic or halogen heating elements, and offer excellent thermal efficiency by transferring heat via radiant heat. In relation to this, a 'functional electric heater' has been disclosed in Patent Document 1 as a prior art. However, as shown in FIG. 1, the heat energy of the heater part (340) is reflected to the reflector (310) and released forward, and at the same time, a blower fan (112) is blown from the rear of the reflector (310) to create wind that moves along the back surface of the reflector (310) and is sent into the inside of the safety net (300) through the reflector air outlet (440). Therefore, there is a problem that the reflector (30) is cooled by the wind, thereby reducing the reflectivity of radiant heat (radiant heat). In addition, as the air forcibly sucked in by the blower fan (112) moves along the back surface of the reflector (310), air flow resistance occurs, which hinders the natural mixing of the heat of the heater part (340) and the outside air, resulting in a significant decrease in the heat transfer efficiency by forced convection and often causing noise such as resonance. It is stated that the background technology or prior art described herein is information possessed by the inventor or acquired during the process of deriving and completing the present invention, and is specified to aid in understanding the technical significance of the present invention and to be useful for prior art search and examination; furthermore, drawing symbols in the prior art are mutually unrelated to drawing symbols in the present invention.
