Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a new floor heater that stores heat using late-night electricity, minimizes daytime electricity consumption, and effectively heats a room.

(Structure of the present invention) The present invention provides a heat equalizing plate on a planar heating element in which a heating element with a small calorific value is laid on the top surface of the insulation material and a heating element with a large calorific value is laid on the back side of the insulation material,
It is characterized in that a heat storage material is provided on the lower surface of the sheet heating element.

(Embodiments of the present invention) Hereinafter, embodiments of the present invention will be explained with reference to the drawings. In the drawings, reference numeral 1 denotes a planar heating element, which is made of a foamed resin such as polyethylene, polystyrene, polyurethane, soft fiber, felt, etc. A foil-shaped or wire-shaped resistance heating element A with a small calorific value is laid on the surface of a fire-resistant heat insulating material C with a low thermal conductivity of several millimeters,
On the back side of the heat insulating material C, a foil-shaped or linear resistance heating element B that generates a large amount of heat is laid. 2 is an iron plate with a thickness of 0.4 to 1.2 mm, an aluminum plate with a thickness of 0.6 to 2 mm, or an aluminum plate with a thickness of 30 to 50 mm, which is provided on the sheet heating element 1.
This is a heat equalizing plate made of asphalt, etc. Reference numeral 3 denotes a heat storage plate provided on the lower surface of the planar heating element 1 and made of concrete or plaster mixed with metal powder or particles, or a single substance thereof. Note that the resistance heating element B of the planar heating element 1 generates heat by applying late-night power and stores heat in the heat storage plate 3, and the resistance heating element A
generates heat by applying daytime power to the heating element A.
The room can be heated by heat radiation from the heat storage plate 3 and the heat radiation from the heat storage plate 3. Switching between day and night power, which is energized to both resistance heating elements A and B, is performed using an appropriate timer switch, changeover switch, etc. Switch depending on the method. Note that 4 in the figure indicates a heat insulating material.

(Effects of the present invention) According to the present invention, as described above, the resistance heating element A with a small heat generation value is laid on the surface of the insulation material C, and the resistance heating element B with a large heat generation value is laid on the back side of the insulation material C. A heat equalizing plate 2 is provided on the planar heating element 1, and a heat storage plate 3 is provided on the bottom surface of the planar heating element 1, so that the resistor with a large amount of heat can be used at night by using low-cost late-night electricity. Heat generating element B generates heat and heat storage plate 3
It stores heat and heats the floor or wall surface, and during the day, energizes the resistance heating element B, which generates a large amount of heat,
Switch to resistance heating element A, which generates less heat, and then
It is economical because the heat radiated from the resistive heating element A and the heat radiated from the heat storage plate 3 that stores heat during the night are radiated into the room through the heat equalizing plate 3 to effectively heat the entire room. It has excellent practical effects, such as being able to keep the difference in indoor temperature between day and night almost constant.
