Utility model registration No. 322608

By the way, in the floor heating unit of Patent Document 1, since the unit main body is heated by the PTC heater, it takes time for the user to wait until the unit main body is heated and the floor surface material reaches the set temperature. There is a problem that it becomes long to some extent and the manufacturing cost of the floor heating unit becomes high.

The present invention has been made in view of the hanging points, and an object of the present invention is to provide a floor heating unit that can be heated faster and can be introduced at a lower cost.

In order to achieve the above object, the present invention is characterized in that the heat source of the floor heating unit and the material of the main body case accommodating the heat source are devised.

Specifically, the following measures were taken for the floor heating unit, which is configured to be placed on the floor or the ground and can heat the feet on which the user is placed.

That is, in the first invention, there is a main body case having an internal space and at least a top plate portion having a rectangular plate shape formed of an aluminum material, and a rectangle housed in the internal space and covering the lower surface of the top plate portion. A plate-shaped heat insulating material, a rectangular plate-shaped floor material that is attached so as to cover the upper surface of the top plate portion of the main body case and on which a user can place his / her feet, and the top plate portion and the heat insulating material. A rectangular plate-shaped heating sheet that is arranged so as to cover the top plate and has carbon heating wires stretched inside, and is connected to the carbon heating wires to apply a current to the carbon heating wires. It is characterized by including a control board capable of adjusting the temperature of the heat generating sheet by flowing and an operation panel connected to the control board to set the temperature of the heat generating sheet.

The second device is characterized in that, in the first device, the surface of the floor surface material is an uneven surface.

The third device is characterized in that the surface of the floor surface material is provided with a marble pattern in the second device.

In the first invention, since the floor heating unit is heated by a heat generating sheet in which carbon heating wires are stretched, the temperature near the heat source is faster than that of the floor heating unit using a PTC heater as in Patent Document 1. Ascend to. Further, the floor heating unit has a structure in which the heat insulating material, the heat generating sheet, the top plate portion and the floor surface material are arranged in this order from the bottom, and further, since the top plate portion is made of an aluminum material, heat is generated. The heat of the sheet is efficiently transferred to the top plate part arranged above by the heat insulating action of the heat insulating material arranged below the heat generating sheet, and quickly moves inside the top plate part due to the high thermal conductivity of the aluminum material. After it diffuses, it reaches the floor surface material located above the top plate. That is, in the floor heating unit according to the first invention, in addition to the temperature near the heat source rising more rapidly than the conventional floor heating unit, the floor surface material can be efficiently heated from the entire lower surface thereof. , The entire floor heating unit can be heated quickly.

Further, in the first invention, since the carbon heating wire, which is cheaper than the PTC heater, is used as the heat source of the floor heating unit, the manufacturing cost can be easily suppressed as compared with the floor heating unit using the conventional PTC heater. As a result, the floor heating unit can be introduced at a lower cost.

In the second invention, since the surface of the floor surface material is less likely to slip, the user's feet and rug placed on the floor surface material surface are less likely to be displaced with respect to the floor surface material, and the usability is improved.

In the third device, the appearance has a natural material feeling and a high-class feeling, so that the design of the entire floor heating unit can be enhanced.

It is a perspective view of the floor heating unit which concerns on embodiment of this invention. It is a top view which showed the internal structure of the floor heating unit of FIG. FIG. 3 is a sectional view taken along line III-III relating to region R in FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiment is essentially merely an example.

FIG. 1 shows a floor heating unit 1 according to an embodiment of the present invention. The floor heating unit 1 is a small rectangular plate-shaped heating device that can be placed on the floor or the ground, and can heat the feet on which the user rests.

As shown in FIGS. 2 and 3, the floor heating unit 1 includes a main body case 2, a floor surface material 3, a heat insulating material 4, a heat generating sheet 5, a control system 6, and a power cord 7.

The main body case 2 includes a rectangular plate-shaped accommodating body 21 made of an aluminum material that opens upward, and a thin rectangular plate-shaped top plate portion 22 made of an aluminum material. 22 closes the opening portion of the housing 21.

Two partition walls 23 extending in parallel in the width direction are provided inside the housing 21 near one end in the longitudinal direction.

The two partition walls 23 divide the internal space of the accommodating body 21 into the first section 21a, the second section 21b, and the third section 21c in order from the other end side in the longitudinal direction, and abut on the top plate portion 22 from below. It is designed to support the top plate portion 22.

Further, inside the accommodating body 21, a plurality of columnar portions 24 having screw holes 24a for screwing the top plate portion 22 to the accommodating body 21 are provided at appropriate positions, and the columnar portions 24 are partitioned. Similar to the wall 23, the top plate portion 22 is brought into contact with the top plate portion 22 from below to support the top plate portion 22.

The floor material 3 is formed of a rectangular veneer plate having a size that allows one adult to place both feet and having a thickness of about 1 mm, and as shown in FIG. 1, covers substantially the entire upper surface of the top plate portion 22. It is attached so as to cover it.

The surface of the floor material 3 is an uneven surface (or a rough surface) and has a marble pattern mainly based on white and black.

The heat insulating material 4 is a plate-shaped hard foam having a thickness, and is housed in the first section 21a of the body 21.

The heat insulating material 4 has a size corresponding to most of the region of the top plate portion 22, and the upper surface of the outer peripheral portion thereof supports the top plate portion 22 from below. As a specific product of the heat insulating material 4, "Zetron (registered trademark)" manufactured by Shimizu Chemical Industry Co., Ltd. can be mentioned.

The heat generating sheet 5 is located between the top plate portion 22 and the heat insulating material 4 so as to cover the lower surface of the top plate portion 22, and meanders inside the rectangular plate-shaped sheet material 51 and the sheet material 51. It is provided with a carbon heating wire 52 stretched so as to extend while being extended.

As shown in FIG. 3, the sheet material 51 is embedded in the heat insulating material 4 so that its upper surface is flush with the upper surface of the outer peripheral portion of the heat insulating material 4. That is, the entire region of the sheet material 51 except the upper surface thereof is covered with the heat insulating material 4.

As shown in FIG. 2, the control system 6 is housed in the third section 21c of the housing body 21 and is connected to the carbon heating wire 52 via the wiring 8 and the power supply board 61 having the push-type power button 61a. It has a control board 62, an operation panel 63 provided with a plurality of operation buttons, and a display 64 capable of displaying the current temperature and the set temperature on a liquid crystal display.

The control board 62 is activated by pressing the power button 61a, and the temperature of the heat generating sheet 5 is adjusted by changing the current flowing through the carbon heating wire 52.

The operation panel 63 can change the set temperature registered in advance in the control board 62 within a predetermined range by pressing each operation button by the user.

The display 64 is provided on the upper surface of the control board 62 near one end in the longitudinal direction, and has a first display unit 64a for displaying the current temperature and a second display unit 64b for displaying the set temperature.

One end of the power cord 7 is connected to the control board 62, while the other end is attached with a plug 7a.

The power cord 7 enters one end of the second compartment 21b from the third compartment 21c in the housing 21, extends in the width direction of the main body case 2, and extends from the other end of the second compartment 21b to the outside of the main body case 2. By folding it, it can be pushed into the second section 21b and accommodated.

Next, the usage method and operation of the floor heating unit 1 will be described.

When using the floor heating unit 1, the user places the floor heating unit 1 on the floor or the like and presses the power button 61a.

Next, the user operates each operation button on the operation panel 63 to set a desired set temperature. Then, the control board 62 controls the current to flow through the carbon heating wire 52 until the temperature of the carbon heating wire 52 reaches the set temperature.

When the user wants to change the current temperature, he / she operates the operation button of the operation panel 63 while checking the second display unit 64b of the display 64 as necessary to change the set temperature.

Here, since the temperature of the carbon heat generating wire 52 to which the current is supplied from the control board 62 rises in a short time as compared with the PTC heater, when the user presses the power button 61a, the conventional PTC heater is used. Compared to the floor heating unit, the temperature near the heat source rises rapidly.

Further, the floor heating unit 1 has a configuration in which the heat insulating material 4, the heat generating sheet 5, the top plate portion 22 and the floor surface material 3 are arranged from the bottom in this order, and further, the top plate portion 22 is formed of an aluminum material. Therefore, the heat of the heat generating sheet 5 is efficiently transferred to the top plate portion 22 arranged above by the heat insulating action of the heat insulating material 4 arranged below and on all sides of the heat generating sheet 5, and the high thermal conductivity of the aluminum material is transmitted. Depending on the rate, the inside of the top plate portion 22 is rapidly moved and diffused, and then reaches the floor surface material 3 located above the top plate portion 22.

That is, in the floor heating unit 1, in addition to the temperature near the heat source rising more rapidly than the conventional floor heating unit, the floor surface material 3 can be efficiently heated from the entire lower surface thereof, so that the floor heating unit 1 can be heated efficiently. 1 The whole can be warmed quickly.

Further, since the floor heating unit 1 uses a carbon heating wire 52 as a heat source, which is cheaper than the PTC heater, the manufacturing cost can be easily suppressed as compared with the floor heating unit using the conventional PTC heater. As a result, the floor heating unit 1 can be introduced at a lower cost than the conventional floor heating unit.

Further, since the surface of the floor surface material 3 is an uneven surface (or a rough surface) and is not slippery, the user's feet and rugs placed on the surface of the floor surface material 3 are less likely to be displaced with respect to the floor surface material 3. , The floor heating unit 1 can be made to have a good usability.

Further, since the surface of the floor surface material 3 is provided with a marble pattern, the appearance can be given a natural material feeling and a high-class feeling, and the design of the floor heating unit 1 as a whole can be enhanced.

In the present embodiment, the entire main body case 2 is made of an aluminum material, but only the top plate portion 22 may be made of an aluminum material.

Further, the aluminum material constituting the main body case 2 may be not only a pure aluminum material but also an aluminum alloy material whose strength is increased by mixing copper or manganese, for example.

Further, in the present embodiment, Zetron (registered trademark, manufactured by Sekisui Chemical Co., Ltd.) is used as the heat insulating material 4, but the heat insulating material 4 is not limited to this, and other materials can be used as long as the material has improved heat insulating properties. Can be used as.

Further, in the present embodiment, the floor surface material 3 is made of a veneer material, but the present invention is not limited to this, and the floor surface material 3 may be made of a heat-resistant resin or the like.

Further, the carbon heating wire 52 of the present embodiment may be any one using carbon fiber, and for example, a known carbon heater may be applied.
