Description

  The present invention relates to a floor heater used on a floor.

  In recent years, flooring has been used in ordinary houses. Compared with tatami mats and carpets, the flooring surface is glossy and looks good. Also, the flooring surface is smooth and easy to clean. Furthermore, the flooring is excellent in terms of strength and wear resistance. For this reason, flooring is widely used not only when building new houses but also when renovating old houses. In particular, the penetration rate of flooring in the kitchen is very high.

  In general, the kitchen is often provided in a place with poor sunlight. For this reason, the kitchen with flooring becomes very cold in the winter. In addition, if the kitchen is ventilated with a ventilation fan, the cold air from other places in the house can easily flow into the vicinity of the floor of the kitchen, and the kitchen tends to get cold. Housewives at home often work in the kitchen for a long time, so it is very important for them to take measures against the cold in the kitchen. However, it is difficult to prevent the cold that comes from your feet, even if you wear slippers or thick socks.

Therefore, as a cold protection measure in a floored kitchen, floor heating equipment is installed under the floor (see, for example, Patent Document 1).
Japanese Patent No. 3753566

However, the construction of installing a floor heating facility under the kitchen floor tends to be large-scale and tends to increase the construction cost. Therefore, it is difficult to easily perform the construction of installing a floor heating facility under the kitchen floor.
Therefore, instead of installing a floor heating facility under the floor of the kitchen, it is conceivable to lay a carpet under the feet to prevent the cold air from being directly transmitted to the feet. However, since carpets are densely populated, dust or the like tends to accumulate in the gaps between the fibers. It is difficult to cleanly remove such dust and the like even if a vacuum cleaner is used. Moreover, pests such as ticks are likely to propagate between the carpet fibers.

For this reason, the carpet must be frequently cleaned and disinfected with sunlight. Caring for such carpets is a cumbersome task for housewives.
The present invention solves the above problems, and its purpose is to provide a floor heater that can be easily installed and maintained, is always clean, and is comfortable to the user. .

The present invention has the following configuration in order to solve the problem. The floor heater according to the first aspect of the present invention is a floor heater that is used by being laid on the floor, and is provided with a base part on the back side, a heat insulating part provided above the base part, A heating plate provided on the upper side and a surface plate portion provided on the upper surface of the heating element, and a plate material formed from wood that has been treated with smoke while heating is laid on the surface plate portion Has been.
Since the plate material is laid on the surface plate portion, the grain of the plate material can be seen. The surface plate has a beautiful appearance and is excellent in strength and wear resistance. The surface plate portion is easy to clean, dust and the like are not easily collected, and insects such as ticks are also difficult to propagate.

It is also possible to enjoy the scent of wood resulting from the board.
Since the heat insulating part exists between the heat generating part and the base part, it is suppressed that heat from the heat generating part escapes to the floor through the base part. The heat from the heat generating part is efficiently transmitted to the plate material of the surface plate part.
When the wood is heated and smoked, the stress inside the wood is removed and the inside of the wood is dried, so that the wood is less likely to be bent or cracked. As a temperature range which heats wood, the range of 80-140 degreeC can be mentioned, for example.
In the following description, the “treatment of burning wood with smoke while heating” is referred to as “smoke treatment”.

Since the plate material laid on the surface plate part is made of smoke-treated wood, even if heat is transmitted from the heat generating part to the plate material, the size and shape of the plate material may be distorted or cracked. It is suppressed. Also, even if the floor heater is laid in a place where the humidity tends to be high, such as the floor of a kitchen, or in a place where drying is severe, the size and shape of the plate material on the surface plate will be distorted or cracked. Can be prevented.
Since the plate material of the surface plate part has been subjected to smoke treatment, it is possible to prevent the generation of decaying fungi and to prevent damage by insects such as termites.
Since the floor heater can be used as long as it is laid on the floor, it is easy to install and the floor heater can be moved easily.

A floor-standing heater according to claim 2 is the floor-standing heater according to claim 1, wherein a plurality of the plate members are laid on the surface plate portion, and unevenness is formed on a side surface of the plate member. The concaves and convexes on the side surfaces of the adjacent plate members are fitted to each other.
Since the unevenness | corrugations of the side surface of an adjacent board | plate material are mutually fitted, it can prevent that the heat-emitting part below is visible from between adjacent board | plate materials.

A floor-standing heater according to a third aspect of the present invention is the floor-standing heater according to claim 1 or 2, wherein the surface of the plate material is provided with a grain.
A plurality of wood grain runs on the surface of the plate material, and a wood layer exists between the wood grain. The grain is harder than the woody layer. When the surface of the plate material on which the grain appears is ground with a wire brush or the like, the wood layer is easily scraped off. Then, the wood grain remains without being scraped off, and the surface of the plate material is in a state where the remaining wood grain is raised and protruded.
When a person sits on a plate material having a grained surface, a gap is formed between the skin and the plate material, air permeability is secured, and the skin in contact with the plate material is less likely to be stuffy. By stopping the heat generation in the heat generating part, people can comfortably sit on the floor heater even in summer. Moreover, since the grain presses the skin, a massage effect is also obtained.

A floor heater according to a fourth aspect of the present invention is the floor heater according to any one of claims 1 to 3, wherein a cushioning material is mounted on the lower side of the base portion. ing.
Since the cushioning material is mounted on the lower side of the base of the floor heater, it is possible to prevent the base of the floor heater from directly contacting the floor surface when the floor heater is laid on the floor. Therefore, even if a person moves on the floor heater and the floor heater is displaced on the floor, the base of the floor heater can be prevented from being damaged.
As the buffer material, for example, woven fabric, non-woven fabric, rubber, resin or the like can be used. If the cushioning material is formed of rubber, resin or the like, the static frictional force acting between the cushioning material and the floor surface can be increased, and the floor heater can be prevented from moving on the floor.

The floor heater according to claim 5 is the floor heater according to any one of claims 1 to 4, wherein the heat generating portion disperses conductive particles in a polymer. A PTC heating element.
A PTC heating element in which conductive particles are dispersed in a polymer generates heat when energized. This PTC heating element can be formed in a film shape. If a PTC heating element is printed on the basis of a film or the like, a thin sheet-like heating part can be formed. If the thickness of the heat generating portion is reduced, the thickness of the floor heater can be reduced. If the thickness of the floor heater is reduced, the difference in height between the floor heater and the floor can be reduced, preventing people from tripping, and reducing the weight of the floor heater. You can also.
Note that “PTC” of the PTC heating element is an abbreviation of “Positive Temperature Coefficient” and means a positive temperature coefficient.

  Since it is a floor-mounted heater as described above, it can be easily installed and cared for, can always be kept clean, and is comfortable for the user.

The best mode for carrying out the present invention will be described with reference to FIGS. FIG. 1 is a top view of a floor heater according to the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is a perspective view of a plate material.
As shown in FIGS. 1 and 2, the floor heater 10 includes a base part 12, a heat insulating part 16, a heat generating part 18, a surface plate part 20, and a frame part 40.
The pedestal 12 is made of a single rectangular veneer plate, is water-resistant and has water resistance.
The heat insulating portion 16 is made of a single foamed polyethylene sheet and has innumerable small bubbles. The shape of the heat insulating part 16 is the same rectangle as the base part 12, and the heat insulating part 16 is stretched over the base part 12.

The heating part 18 is a so-called PTC heating element. The PTC heating element of the heat generating portion 18 is obtained by printing an ink in which conductive particles are dispersed in a polymer on a polyethylene terephthalate film, and is configured to generate heat when energized. The shape of the PTC heating element of the heat generating part 18 is the same rectangle as the base part 12, and is stretched over the heat insulating part 16.
The surface plate portion 20 includes a plurality of plate materials 22 and covers the heat generating portion 18. The plate 22 is formed by processing wood that has been smoke-treated.

  As shown in FIG. 3, the single plate member 22 has a rectangular shape, and a large number of wood grains 26 run on the surface 24. The wood grain 26 is a hard part called a so-called winter eye. A soft woody layer exists between the winter eyes forming the wood grain 26. This woody layer is the so-called Natsume 28. The surface 24 of the plate material 22 is ground by a wire brush, the Natsume 28 is scraped off, and the wood grain 26 is raised and protruded without being scraped off.

Of both side surfaces 30A, 30B continuous in the longitudinal direction of the plate member 22, a concave groove 32 is formed continuously in the longitudinal direction on one side surface 30A. Moreover, the convex part 34 is continuously formed in the longitudinal direction at the other side surface 30B. The shape of the convex portion 34 is a shape corresponding to the concave groove 32.
A plurality of plate members 22 are spread on the heat generating portion 18 with the surface 24 facing upward, and cover the heat generating portion 18. In the two adjacent plate members 22, the side surface 30 </ b> A having the concave groove 32 of one plate member 22 and the side surface 30 </ b> B having the convex portion 34 of the other plate member 22 face each other and protrude into the concave groove 32. The part 34 is fitted. The plurality of plate members 22 spread on the heat generating portion 18 are joined together so that the surface 24 of the plate member 22 is continuous and forms a single wide surface 36 without any step.

The base part 12, the heat insulating part 16, the heat generating part 18, and the surface plate part 20 constitute a main body 38.
A frame portion 40 surrounds the periphery of the main body 38. The frame part 40 is formed by molding smoked wood. The frame part 40 has a rectangular hole 42 into which the main body 38 fits.
A part of the inner wall surface 44 of the hole 42 faces the side surface 30 </ b> A of the plate 22 located at the end of the main body 38. A convex portion having the same shape as the convex portion 34 is formed on the inner wall surface 44 of the portion facing the side surface 30A. The convex portion of the inner wall surface 44 is fitted in the concave groove 32 on the side surface 30 </ b> A of the plate member 22 located at the end of the main body 38.

Another part of the inner wall surface 44 of the hole 42 faces the side surface 30 </ b> B of the plate member 22 located at the end of the main body 38. A concave groove having the same shape as the concave groove 32 is formed on the inner wall surface 44 of the portion facing the side surface 30B. The convex portion of the side surface 30 </ b> B of the plate member 22 located at the end of the main body 38 is fitted in the concave groove of the inner wall surface 44.
Of the main body 38, the edge portions of the base portion 12, the heat insulating portion 16, and the heat generating portion 18 are screwed together with the back surface 46 of the frame portion 40. The back surface 46 of the frame part 40 and the back surface 14 of the base part 12 form a single wide surface without a step, and one sheet covers the entire surface (that is, the back surface of the floor heater 10). The non-woven fabric 50 is affixed. The nonwoven fabric 50 forms a cushioning material. As the nonwoven fabric 50, for example, a needle punched nonwoven fabric can be used.

The height of the edge on the hole 42 side of the frame portion 40 is the same as the height of the surface 36 formed continuously by the surface 24 of the plate 22. The height of the frame portion 40 gradually decreases from the hole 42 side to the outer peripheral edge 48 side, and the height of the frame portion 40 at the outer peripheral edge 48 is almost zero.
A socket 52 is formed in a part of the frame portion 40. The socket 52 is connected to the heat generating part 18 and is configured to be able to energize the heat generating part 18 through a power cord 54 inserted into the socket 52.

Next, the operation will be described.
A person lays the floor heater 10 in an arbitrary place in the house. For example, the floor heater 10 can be laid on a flooring kitchen floor.
Since the nonwoven fabric 50 is affixed to the back surface of the floor heater 10, the back surface 46 of the frame portion 40 and the back surface 14 of the base portion 12 do not directly contact the flooring, and the back surface of the floor heater 10 is flooring. It can be prevented from being damaged. Further, even if a person moves on the floor heater 10 and the floor heater 10 is displaced, the back surface of the floor heater 10 can be prevented from damaging the flooring.

Moreover, since the base part 12 of the floor heater 10 is made of water-resistant plywood, it is difficult to be damaged even if water spills on the floor.
In winter, the power cord 54 is inserted into the socket 52 of the floor heater 10 to energize the heat generating portion 18. The PTC heating element of the heating part 18 is energized and generates heat.
The heat generated in the heat generating part 18 warms the plate member 22 of the surface plate part 20 spread on the heat generating part 18. Since the heat insulating part 16 exists under the heat generating part 18, the heat generated in the heat generating part 18 hardly transfers to the heat insulating part 16 and escapes from the back side of the floor heater 10 to the kitchen floor. Is slightly suppressed. A person who stands on the floor heater 10 in the winter can feel the heat of the plate 22 on the soles and is warm and can prevent the cold of the feet.

The plate material 22 of the surface plate portion 20 is formed by processing smoked wood and is sufficiently dry. Therefore, even if the heat generated in the heat generating portion 18 is transmitted to the plate material 22, the plate material 22 is not easily deformed, and the plate material 22 is not easily warped or cracked. Further, since the plate material 22 hardly shrinks, it is possible to prevent the heat generating portion 18 from being seen between the plate materials 22.
In summer, the power cord 54 is removed from the socket 52 of the floor heater 10. Since the heat capacity of wood is large, the touch of the plate 22 of the surface plate 20 is cool even in summer. For this reason, the person who stood on the floor heater 10 in summer has cool feet. That is, the floor heater 10 can be used as a rug even in seasons other than winter.
It should be noted that the power cord 54 pulled out from the socket 52 may be stored in a place where it does not get in the way.

Since the surface 24 of the plate material 22 of the surface plate portion 20 is in a state in which the grain 26 is projected, the soles of the person standing on the floor heater 10 do not adhere to the surface 24 of the plate material 22, A gap is formed between them to ensure air permeability. As a result, the stuffiness of the soles disappears and the person standing on the floor heater 10 does not feel the skin stickiness.
Moreover, since the grain 26 of the surface 24 of the board | plate material 22 stimulates a sole moderately, the effect similar to having massaged the sole is acquired.
From the plate material 22 of the surface plate portion 20, there is a scent of wood. In particular, when the plate 22 is warmed by the heat of the heat generating portion 18, the scent of wood rises strongly. This scent makes it possible to deodorize the place where the floor heater 10 is laid.

Exposed on the surface side of the floor heater 10 are the plate material 22 and the frame portion 40 of the surface plate portion 20, which are formed by processing smoked wood. Therefore, if the surface is wiped with a rag, the dirt is easily removed and dust and the like are not easily collected. For this reason, various germs and the like are difficult to propagate and are always hygienic.
Since the floor heater 10 is only laid on the floor, it can be easily moved. The floor heater 10 does not interfere with floor cleaning.
On the surface plate portion 20 of the floor heater 10, a single wide surface 36 without a step is formed, and the edge of the frame portion 40 on the hole 42 side is the same height as the surface 36. Moreover, it is gradually lowered from the edge on the hole 42 side of the frame portion 40 to the outer peripheral edge 48 side. Thereby, it is possible to prevent a person from tripping over the floor heater 10.

It is a top view of the floor heater which concerns on this invention. It is the sectional view on the AA line of FIG. It is a perspective view of a board | plate material.
