Description

Direct thermal conductivity solid wood flooring

The present invention relates to a floor, and more particularly to a floor with a thermally conductive structure. Background art

The traditional heating technology has changed, and the floor heating has become a popular trend, so the floor heating floor has emerged. At present, the solid wood composite floor and the reinforced floor on the market mainly rely on the wood body to conduct heat dissipation. Due to the low thermal conductivity of the wood, the heat conduction rate is slow, resulting in floor heating. The heat consumption is very high, and these floors are just materials that can be used for floor heating, and are not really dedicated floor heating. Moreover, these floor heating floors are mainly laid on the floor heating floor. The disadvantage is that the floor cement layer is first heated and then transmitted to the floor floor. This continues to heat for a long time and requires long-term low temperature operation, most of the heat. It is absorbed by the floor and the wall, which consumes a lot of energy.

So, someone developed a fast-heating floor heating floor, such as the public number

"CN 1693626", the Chinese patent entitled "Composite floor heating floor", consists of a front panel, a sub-plate, a core board and a bottom plate. The core board is provided with a transverse heat-conducting groove, and the bottom plate is provided with a longitudinal heat-conducting groove, a transverse heat-conducting groove and a longitudinal direction. The heat conducting groove is filled with a heat conducting medium layer, the longitudinal heat conducting groove is two, the distance between the two longitudinal heat conducting grooves is 20-35 mm, the transverse heat conducting groove is plural, and the distance between the adjacent two horizontal heat conducting grooves is 25 — 40mm, the heat conductive medium layer is aluminum or copper.

However, the above patents have some shortcomings. First, the floor is prone to deformation when the floor is inflated and contracted, resulting in unevenness of the floor. Second, the floor is directly in contact with the ground, and the heat loss rate is still high. 3. The floor thickness is large. No space saving.

Therefore, it is necessary to newly develop a floor heating floor with low heat loss rate and good stability. Summary of the invention

The technical problem to be solved by the present invention is to provide a floor heating floor with low heat loss rate and stable structure in view of the shortcomings of the existing direct heat conduction floor heating floor with high heat loss rate and insufficient structure. It directly transfers the heat of the floor heating pipe to the interior of the floor through the slotted groove in the lower part of the floor and the concave keel groove, which solves the problem of high energy consumption and environmental protection of the traditional floor heating technology, and utilizes the dovetail slot between the upper and lower layers. The swallow edge portion suppresses the deformation warpage of the upper surface plate, so that the floor has the function of resisting deformation and warping.

In order to solve the above technical problem, the present invention adopts the following technical solutions:

The utility model relates to a direct heat-conducting solid wood keel floor, comprising a substrate, a panel, a heat conducting medium layer, a keel and a floor heating pipe, the keel is arranged at the bottom of the substrate, a heat conducting medium layer is arranged between the substrate and the panel, and the upper surface of the substrate and the lower part of the panel The surface is respectively provided with a plurality of parallel dovetail slots and corresponding dovetails, and the dovetails are correspondingly embedded in the dovetail slots; the upper surface of the keel is provided with longitudinal grooves; the upper half of the floor heating pipes are longitudinally embedded on the two sides of the substrate, And partially in contact with the thermal medium layer, the lower half of the floor heating tube is embedded in the longitudinal groove of the keel.

The heat-conducting medium layer rapidly conducts heat in the floor heating pipe and distributes it in various positions on the floor to avoid heat loss outside the floor. The dovetail groove and the dovetail are used to connect the substrate and the panel, and the interaction between the dovetail groove and the dovetail is suppressed. The panel is deformed and warped by heat, so that the floor has the function of resisting deformation and warping, and avoids the rise or fall of the floor when it is heated, which brings troubles of unevenness of the floor.

In the above technical solution, the two ends of the substrate are provided with notch grooves, and the substrate and the substrate are butted so that the notch groove forms a floor heating pipe groove having a cross-sectional shape of a half arc shape, and a floor heating pipe is disposed in the floor heating pipe groove, and the floor heating pipe groove is disposed below Corresponding to the longitudinal groove of the keel, the floor heating pipe is enclosed between the floor heating pipe groove and the keel groove. The use of the keel groove has two beneficial effects: 1. Avoiding direct contact between the floor heating pipe and the ground, and having the technical effect of heat preservation and further reducing the heat loss on the floor heating pipe; 2. The floor heating pipe does not occupy an extra height after the keel groove is set. It has the characteristics of effectively preventing the heat loss of the floor heating pipe under the premise of ensuring the comfort of the floor.

Based on the above technical solution, the edge of the panel is provided with a concave and convex side, and the longitudinal section is In the "L" shape, when the panels are butted against each other, the concave and convex sides of the panel are aligned with each other.

Based on the above technical solution, the heat conductive medium layer is a mixed coating composed of nano aluminum nitride and resin glue, or a mixed coating composed of nano carbon fiber powder and resin glue, and the mixed coating layer can be directly coated on the panel. On the bottom surface.

Based on the above technical solution, the panel is a natural wooden floor. The benefits of using natural wood flooring are environmentally friendly.

In addition to the above technical solution, the heat conductive medium layer may also be a wire or a sheet of metal or alloy material, which intersects the arrangement direction of the floor heating pipe. The metal is copper, aluminum or iron. It can also be other metal or alloy materials with good thermal conductivity.

Based on the above technical solution, the wood grain direction of the substrate intersects with the panel grain direction, and the effect of intersecting at right angles is optimal, and the substrate material is finger joint plate or integrated wood made of fast-growing wood. The advantage of the cross-grain direction of the substrate and the direction of the panel grain is that it can increase the pressure resistance of the floor heating floor, allowing it to withstand greater pressure.

The technical effects of the present invention are embodied in:

1. High thermal conductivity and low heat loss. The floor heating pipe is embedded in the gap between the notch groove and the keel groove of each floor. The floor heating pipe directly transfers heat to the inside of the floor through the heat conduction medium layer in the floor, because the floor is laid in the keel groove. Above, there is no direct contact between the floor and the ground, and the heat energy is not transmitted to the floor and the wall;

Second, the structure is stable and not easy to deform;

Third, not in direct contact with the floor, comfortable to use;

4. The panel adopts natural wood, and at the same time, the chemical-containing insulating material such as benzene board is omitted, the volatilization of harmful substances is reduced, the height of the paving is lowered, and the indoor space is healthier and more environmentally friendly.

5. It is convenient to disassemble and install, which is convenient for future maintenance and replacement.

Sixth, the paving height is low, the paving height of the traditional floor is generally 7-8 cm, and the paving height of the product is only 3-4 cm;

Seven, the number of layers is small, saving glue.
