Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a heater configured with a planar heating element such as an electric carpet. (Prior Art) Conventionally, this type of heater has a heating element disposed in a planar manner, with one side of the heating element serving as a heat radiation surface, and the other side of the heating element having a first air passage,
The feature is that a blower mat is provided that blows air through a second airflow path provided with a rectifying blade that communicates with the first airflow path. By installing a ventilation duct on the other side and forcing wind through the duct, the wind absorbs heat, and the warmed air is discharged indoors. It generates heat convection, and uses the three elements of heat radiation, heat conduction, and mature convection to provide comfortable heating. In this case, the air outlet was configured to be from the air passage of the air blowing mat, or the air was blown out in one direction. (Problems to be Solved by the Invention) In other words, Figs. 6(a) and 6(b) show the heating effect when heating a room through the planar heater body l゜, and (Fig. aJ shows the heating effect). In the case of a heater without an air outlet, (b) the air outlet 2" is provided on only one side, and the air outlet is unidirectional; in such a Yokoui heater, (a)
Although the temperature distribution is somewhat wider than that of the previous model, there was a problem in that the indoor air convection and temperature distribution were uneven, as shown in Figure (l)). The present invention was proposed in consideration of the above, and its purpose is to improve the circulation of indoor air, to equalize the temperature distribution, and to create a heater with a more uniform surface temperature distribution. It is to provide. (Means for solving 11!!It) In the present invention, first, one side of a heating element disposed in a planar manner is used as a heat radiating surface, and one side of the heating element is provided with an air passage and a rectifying blade that forms the air passage. In a heater equipped with a blower mat, the above purpose is achieved by arranging the blowers symmetrically with respect to the center of the heater body and providing hot air outlets on both sides. ．． In addition, in a heater in which one side of a heating element arranged in a planar manner is used as a heat dissipation surface, and one side of the heating element is provided with a blower mat equipped with rectifying blades that form an airflow path or a cough airflow path, the blower is used as a heating element. The system is placed diagonally on the main body and has hot air outlets on both sides to achieve the above objectives. (Function) The present invention is constructed as described above, and the blower mat is arranged so that the blower positions are symmetrical or diagonal, and hot air is blown out from both sides, thereby improving indoor air circulation. This improves the temperature distribution and makes the temperature distribution more uniform.Also, since hot air is blown from both sides, the surface temperature distribution is more uniform than from one side.
