Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a floor heating device that uses hot air, and provides a floor heating device that is inexpensive and easy to assemble and disassemble.

<Prior Art> Conventionally, a hot air floor heating system formed by joining a plurality of unit panels has, for example, as shown in Fig. 1.
When using a set of nine unit panels arranged in a square, there is a hot air input panel 21 to which hot air is supplied from the hot air supply device 20, a central panel 22 that sends hot air to the periphery, a peripheral panel 23, and a corner panel. Panel 24
At least four types of unit panels with different shapes were required, which increased the manufacturing cost of the panels accordingly. Furthermore, assembly was very troublesome, as the designated unit panel had to be placed at a designated location relative to the hot air supply device 20.

<Purpose> In view of the above, the present invention aims to provide a floor heating device that is inexpensive and easy to assemble and disassemble.

In addition, the present invention is such that while the warm air injected into the unit floor mat group is discharged through the header section into the respective independent communication pipes of the mat main body to the downstream side when viewed from the hot air input side, A hot air floor heating system is provided in which heat is radiated at the pine, raising the surface temperature of the pine, and finally released into the room from the openings of the communicating pipes at the ends of the pine.

Furthermore, in the present invention, when the header part has at least three openings for joining unit floor mats together or for hot air inlet, and when a plurality of unit floor mats are joined, which header part can be connected to each other or for hot air inlet. However, it has a structure that allows hot air to be injected, and is formed as a combination of two types of boards, an upper plate and a lower plate, and after installing the unit floor mat, the header selected as the hot air inlet and all other In order to close off the extra openings in the header, there were two hot air blocking covers of the same shape and one hot air blocking cover of a different shape, with a number equal to the total number of unit floor mats to be joined. Provide hot air floor heating equipment.

<Example> An example of the present invention will be described below with reference to FIGS. 2 and 3. First, FIG. 2 is a perspective view of the hot air floor heating system of the present invention, in which the unit floor mat 1,
A hot air supply device 2, a hot air duct 3 that communicates the hot air supply device 2 and the unit floor mat 1, a header 4 and a mat main body 5 that constitute the unit floor mat 1, and a joint that joins the unit floor mats together. 6,
It consists of a header cover 7 and a header cover 8 that are attached to openings on the periphery of four groups of headers.

FIG. 3 is a perspective cross-sectional view of the unit floor mat, which has a square (approximately 30 cm square) shape and has an upper plate 9.
, a header 4 consisting of a lower plate 10 facing the upper plate 9 and forming a hot air passage, and a joint 11 for joining the unit floor mats 1 together, and any openings on the four sides of the header 4. After joining the mat part main body 5 and the first group of unit floor mats, which are fixed to the opening 4d of the header with an adhesive or the like, they are attached to the header opening 4a and the opening 4b as necessary for hot air shielding. Head lid 7, also joint part 6
It consists of a header lid 8 for covering. The upper plate 9 and the lower plate 10 each have coupling protrusions 11 at four corners for mutual coupling, and the upper plate 9 is provided with a plurality of pillars 12 for supporting the upper and lower plates 9 and 10. The upper and lower plates 9 and 10 are fixed with screws 13 or the like at the coupling convex portions 11 at the four corners. As shown in FIG. 3b, the connecting portion 6 and the header lid 7 are provided with tapered claws 14a, 1 having spring properties.
4b, and claw holes 15a, 15b provided at opposite positions of the upper and lower plates 9, 10.
This combination not only prevents hot air from leaking, but also allows for free removal. The coupling part 6 is attached to the opening 4c, and does not come off due to the protrusions 6a and 6b for preventing coming off. In addition,
When the header 4 is blow molded, there is one opening 4a.
This eliminates the need for a head lid. 4a-4
When c is opened, cutting is performed.

In addition, the hot air outlet of the hot air duct 3 (not shown)
The above-mentioned claw 14 is also provided, so that the hot air duct 3 and the header 4 can be connected without leakage of hot air and can be easily removed. The header lid 8 has a structure in which the part of the joint 6 that protrudes from the header 4 is worn, and has a claw hole 1 at a position opposite to the claw 14c provided in the joint 6.
5c (not shown) is provided to prevent hot air from leaking from the joint 6 of the header located at the end that is not used to join the mats together after the unit floor mat group is assembled, similar to the header lid 7. This eliminates the need to remove it and makes it easy to remove. The mat main body 5 is a communicating tube made of rubber extrusion or the like and having openings 16 and 17 at both ends.

In the above structure, the hot air floor heating system of the present invention is assembled as shown in FIG. Arrange the three pieces horizontally,
By joining the joint portion 6 to the opening 4a of the header 4 facing the joint portion 6, the joining of the mats is completed. Next, the header lids 7 are inserted into the three openings of the header at both ends, leaving the central header opening 4b serving as a hot air inlet.
Further, the joint portion of the end header is covered with a header lid 8. Finally, the hot air supply device 2 and the central header are connected through the hot air duct 3 to complete the assembly.

Therefore, compared to the conventional type, fewer unit floor mats are required to obtain the same heating area (the conventional type is approximately 60 cm square, and the unit floor mat of the present invention is 30 cm x 180 cm); After arbitrarily joining each unit floor mat, hot air ducts can be connected to the openings of all headers, except for the joint provided on the header at the other end. Since there is no need to distinguish between the front and back of the mat itself, by using both sides of the unit floor mat, hot air ducts can be connected to all headers in all directions.

<Effects> As is clear from the above explanation, according to the present invention, a unit floor mat that is easy to assemble and disassemble is combined with a mat part main body as a combination of hollow communicating pipes with one end open to the interior of the room, and the mat connection and
By dividing the unit into two main parts, the header part for the hot air inlet and the header part for the hot air inlet, the number of unit floor mats required to obtain the same heating area is smaller than before, and assembly and disassembly are also easier. Easy.

Compared to the past, the position of the hot air inlet can be chosen from a wider range, which reduces restrictions on floor mat installation.

Since the mat main body has a structure that allows extrusion molding, the length in the longitudinal direction of one unit floor mat can be freely changed, making it possible to easily manufacture unit floor mats of various sizes. It is possible to create a rich product structure.

While conventional unit panels were approximately 60 cm square, the unit floor mat of the present invention has a smaller header section of approximately 30 cm square, and the mat main body can be extruded, reducing the overall mold cost. It can be significantly reduced.

etc., it is easy to assemble and disassemble, the number of mats is small for the heating area, and it has great practical value as it can realize a low-cost warm air floor heating that can be manufactured in a wide variety of products.
