Abstract

PURPOSE: To enhance heat transmission efficiency and unify a temperature distribution by using a copper 3-D mesh structure or a copper alloy 3-D mesh structure for an evenly heating board/a heat storing board of a household floor heater. CONSTITUTION: A household floor heater comprises an expanded polyethylene insulating material 7, a backer plywood 5, a resin hot water circulation pipe or an electric mat heater 3, an evenly heating board-heat storing board 2, and a flooring 1 and so forth, which are laminated in this order from the lower part. In this case, a copper 3-D mesh structure or a copper alloy 3-D mesh structure is used for the evenly heating board-heat storing board 2. A metal 3-D mesh structure having a high porosity is of light weight and good conductor, and contains a large volume of air, which makes it possible to provide a large heat storing effect. The porosity of the evenly heating board and heat storing board 2 is 96 to 98%, which enables the air to be stored in the voids. It is, therefore, possible to continue a heating by radiated heat for a relatively long time, even after the heat source is cut off.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heater used at home.

[0002]

2. Description of the Related Art A conventional domestic floor heater is disclosed in Japanese Patent Laid-Open No. 2-4.
1 and 2 as disclosed in Japanese Patent Publication No. 120
It has a structure like. That is, in FIG. 1 and FIG. 2, from the bottom, a heat insulating material 8 made of foamed polyethylene, a discarding laminated plate 6, a hot water circulating pipe made of resin or an electric mat heater 4, a foamed resin heat storage plate 3, a metal foil soaking plate 2, the flooring 1 and the like.

[0003]

In such a structure, the heat equalizing plate of the two metal foils has a role of conducting heat to make the heat uniform, and the three foamed resin heat storage plate is a heat generating plate. It is installed for the purpose of storing. Therefore, in the two metal foil soaking plate,
It was not efficient in heat conduction. Also, the temperature distribution was not good. In order to solve these problems, a metal having a high heat conductivity may be used, but the metal has a high specific gravity and becomes heavy, and it is not practical because the heat storage effect by air like a foam resin cannot be expected.

An object of the present invention is to provide a floor heater capable of improving the heat transfer efficiency, making the temperature distribution uniform and eliminating the metal foil soaking plate 2.

[0005]

The floor heater of the present invention comprises a heat-resistant flooring, a metal foil soaking plate, a foamed resin animal heat plate, a resin hot water circulation pipe or an electric mat heater, a joist, and a throw-away member. Characterized by using a copper three-dimensional mesh structure or a copper alloy three-dimensional mesh structure as a heat equalizing plate / heat storage plate for a household floor heater composed of a laminated board, joists, and foamed polyethylene insulation .

That is, a high-porosity metal three-dimensional mesh structure is used in a household floor heater, and copper or a copper alloy is used for this, so that the heat conductivity is light and the air porosity is high. Since it contains a large amount, the structure uses a three-dimensional mesh structure having a large heat storage effect.

FIG. 3 is a sectional view of a hot water circulation pipe type floor heater in which a three-dimensional mesh structure of copper and copper alloy is installed, and FIG. 4 is a mat heater type floor heater of copper and copper alloy tertiary. It is sectional drawing which installed the original mesh structure. In each case, a soaking plate and a copper and copper alloy three-dimensional mesh structure as a heat storage plate are installed near the heat source. In FIG. 3, a heat source pipe is sandwiched and installed, and in FIG. 4, a copper and copper alloy three-dimensional mesh structure is installed on a mat heater to form a soaking plate and a heat storage plate.

The copper and copper alloy three-dimensional network structure in the present invention is used as a heat equalizing plate or heat storage plate for a floor heater, for example, other metal, gold, silver, nickel, aluminum, titanium, chromium, tin, manganese. Although a metal three-dimensional network structure made of a metal such as tungsten or cobalt may be installed, a copper and copper alloy three-dimensional network structure is preferable in consideration of price heat conduction and the like.

[0009]

According to the present invention, mesh copper is provided by installing it in a household floor heater as the copper 2-copper and copper alloy three-dimensional mesh structure heat equalizing plate and heat storage plate of FIGS. 3 and 4. The heat is transferred quickly, the heat is evenly distributed, and the temperature rises quickly. Further, the porosity of the copper and copper alloy three-dimensional network structure is 96 to 98%, and even if the heat source is cut off because air storage is possible in the voids.
Heating continues with subsequent heat dissipation.

EXAMPLES The present invention will be described below with reference to Examples and Comparative Examples, but the present invention is not limited to these Examples.

A model as shown in FIG. 4 was constructed as a floor heater. First of all, the size is 1 m ^2, and the floor plate at the top is
Using general flooring material, soaking plate, heat storage plate,
A copper three-dimensional network structure having a porosity of 97% and a thickness of 10 mm was installed. A styrofoam thickness of 100 mm was used as the heat insulating material, and a home floor heater as shown in FIG. 4 was assembled. The heater is placed under the copper three-dimensional mesh structure (equalizing plate, heat storage plate), linked with an automatic temperature controller, and the sensor automatically attaches the temperature measuring element to the center of the assembled floor heating upper surface. It was supposed to be controllable. As described above, the assembled home floor heater is used as a heat equalizing plate, a heat storage plate, and a metal foil, respectively.
A conventional product made of resin and a copper three-dimensional mesh structure were installed, and the floor surface temperature was measured and compared. FIG. 5 shows the temperature rise characteristic, and FIG. 7 shows the distribution of the floor surface temperature when the copper three-dimensional mesh structure is used. Household floor heaters that use a copper three-dimensional mesh structure have a heating time that is half that of conventional products and a cooling time that is longer than that of conventional products. The temperature distribution is shown in FIG.
Compared to the floor temperature distribution of the conventional structure, it is reduced to about 1/2.

[0012]

EFFECTS OF THE INVENTION According to the present invention, by using the copper three-dimensional mesh structure of the soaking plate for floor heating and the heat storage plate currently used, Since the thermal conductivity of copper is high, the temperature rising time is short. In addition, the heating is spread to every corner. 2. Since the porosity of the copper three-dimensional mesh structure is high, air heat storage becomes large, and heating continues even if the heat source is turned off early. Furthermore, due to the antibacterial effect of copper, even if the soup is spilled and soaked in the heat equalizing plate or the livestock heat plate, bacteria and mold cannot grow and die, so a hygienic environment can be created. By using the three-dimensional mesh structure as a heat equalizing plate and a heat storage plate of a floor heating system for home use, an economical and hygienic environment can be created.
