Description

Floor heating system

Technical Field

The application relates to the field of floor heating.

Background

The Floor Heating is short for Floor radiation Heating, and is called radiation Floor Heating, the whole Floor is uniformly heated by using a heat medium in a Floor radiation layer as a radiator, and heat is supplied to the indoor space by using the Floor in a radiation and convection heat transfer mode, so that the purpose of comfortable Heating is achieved. The heat transfer medium is divided into water ground heating and electric ground heating according to different heat transfer media.

The water floor heating is a heating mode which heats water to a certain temperature, conveys the water to a water pipe heat dissipation network under the floor and realizes the heating purpose by heating the floor.

The electric floor heater is a semi-transparent polyester film which can generate heat after being electrified and is made by processing and hot-pressing conductive special printing ink and metal current carrying strips between insulating polyester films. When the heating device works, the carbon-based ink is used as a heating body, and heat is sent into a space in a radiation mode, so that a human body is warmed.

However, the traditional water floor heating system and the traditional electric floor heating system have the problems of slow heat transfer rate and long startup waiting time. Wherein the temperature of water underfloor heating system need keep 50 ~ 60 ℃ just can let the user experience warmly, but heat low-temperature water to 50 ~ 60 ℃ in cold weather and need consume a large amount of energy, and the heat loss rate of 50 ~ 60 ℃ high-temperature water is high in cold day moreover, leads to underfloor heating system's energy consumption to further increase. In addition, the water temperature in the ground heating pipe is kept at 50-60 ℃ for a long time, and scales are easy to form. The traditional electric floor heating system has the problems of low heat transfer rate and high energy consumption due to structural defects.

The floor heating system can be divided into a dry floor heating system and a wet floor heating system according to different paving structures.

The dry floor heating is also named as ultra-thin floor heating, because the installation mode of the dry floor heating does not need floor heating backfill compared with the installation mode of common floor heating, the dry floor heating is also named as dry floor heating, and because a backfill layer is not needed, the occupied layer height is reduced compared with the common floor heating, and the ultra-thin floor heating is also named as ultra-thin floor heating.

However, the conventional dry floor heating has a higher manufacturing cost than the wet floor heating, and cannot be installed under floor finishing materials such as floor tiles, marble, etc., because these materials must be fixed using cement when being laid. The dry floor heating is not provided with a pea stone backfill layer, the floor heating coil is easy to damage, the service life of the floor heating is reduced to a certain extent, and even later maintenance problems such as water leakage and the like are easy to occur.

The wet floor heating is the mature installation process of the water heating floor heating, and is widely applied to the electric heating floor heating. The wet floor heating is relatively low in price and is the leading technology of the domestic floor heating market. The wet type is to embed the floor heating pipeline with concrete and then lay ground materials such as ground, ceramic tiles and the like on the concrete layer. The layer of concrete not only plays a role in protecting and fixing the water heating pipeline, but also is a main channel for transferring heat. The concrete layer can enable heat to be uniformly distributed, and the condition of local overheating or overcooling is reduced.

However, in wet floor heating, sand and stone mixed soil layers must be poured, so that the average weight is heavy, and the bearing capacity of the wet floor heating is about 8 times that of a radiator mode. In the wet floor heating, heat preservation is firstly paved on a cement surface, then pipes are arranged, then cobble cement is used for pouring and leveling, and a ground decoration layer is added, so that the height is generally 8 centimeters. In addition, the construction cycle of wet-type ground heating is long, and the requirement for constructor's specialty is high, in case bury in the water pipe or the electric heat membrane of subsurface emergence damage, must demolish concrete filling layer, and is very complicated.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings of the embodiments of the present application. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the application without any inventive step, are within the scope of protection of the application.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application belongs. The use of the terms "a" or "an" and the like in the description and in the claims of the present application do not denote a limitation of quantity, but rather denote the presence of at least one.

In the description of the present specification and claims, the terms "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present application and simplifying the description, but do not indicate or imply that the referred device or unit must have a specific direction, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.

Embodiments of the present application will now be described with reference to the accompanying drawings.

The first embodiment is as follows:

fig. 1 to 5 show a preferred embodiment of the floor heating system of the present application, which is an electric heating structure comprising an electric heating film 1 heated by electricity and a plurality of floor boards 2 above the electric heating film. The electric heating film 1 is commercially available, and is mainly composed of an electric heating wire and an insulating film enclosing the electric heating wire. The electric heating film 1 is paved on the ground 4 (generally indoor ground, including floor surface), and the floor block 2 is paved on the upper surface of the electric heating film 1. The electric heating film 1 is paved on the ground 4, and does not mean that the electric heating film 1 is necessarily in direct contact with the ground 4.

Each floor board 2 is composed of a metal honeycomb board 201, a panel 202 attached and fixed to the upper surface of the metal honeycomb board, and a floor buckle 203 fixedly connected to the side edge of the metal honeycomb board. The metal honeycomb plate 201 is laid above the electric heating film 1 and is connected with the electric heating film 1 in a heat conduction mode, and all the floor blocks 2 are connected through floor buckles 203 buckled with each other.

It can be seen that each floor block 2 of the floor heating system is directly paved above the electric heating film 1, and each floor block 2 is connected with each other into a whole by means of the floor buckle 203 of the floor block 2, the construction method of pouring sand, stone and concrete is not needed, the full-dry construction is adopted, the installation efficiency is high, and the floor block can be easily dismantled for reuse. Moreover, the heat conduction rate of the metal honeycomb plate is high, the heat of the electric heating film 1 below can be quickly guided to the panel 202 and then dissipated to the indoor through the panel 202, and the indoor temperature is quickly increased.

The (upper surface of the) panel 202 is exposed to the environment for people to step on. The panel 202 is typically a marble, tile, wood or plastic board, which includes a relatively flexible rubber or plastic board, in this embodiment the panel 202 is a wood board, and the thickness of the wood board is only a few millimeters.

The panel may also be a wear-resistant coating coated on the upper surface of the metal honeycomb panel 201, and the wear-resistant coating has a certain thickness and is in a fixed state, and is in a shape of a "plate", which is also an optional panel structure.

The metal honeycomb panel 201 of the present embodiment also includes, as with the conventional honeycomb panel: an upper plate 201a, a lower plate 201b arranged in parallel below the upper plate, and a honeycomb core layer 201c fixedly connected between the upper plate and the lower plate.

Further, the upper plate body 201a is adhesively fixed to the upper surface of the honeycomb core layer 201c by an adhesive (hot melt adhesive film), and the lower plate body 201b is adhesively fixed to the lower surface of the honeycomb core layer 201c by an adhesive (hot melt adhesive film). Of course, the upper and lower plate bodies and the honeycomb core layer can also be welded and fixed.

The panel 202 is adhesively fixed to the upper surface of the upper plate body 201a by an adhesive, and thus the panel 202 is bonded to the metal honeycomb plate. In order to improve the compression and impact resistance of the panel 202 in the vertical direction and prevent the panel 202 from being broken when it is subjected to a vertical load or a vertical impact (especially, when the panel is a marble plate or a tile plate), the adhesive for bonding the panel 202 and the upper plate 201a is preferably continuous and dense, so that a continuous and dense adhesive layer (not shown) is formed between the panel 202 and the upper plate 201 a.

The "continuous and dense adhesive layer" can be realized by increasing the amount of the adhesive, or by sandwiching a hot-melt adhesive film between the panel 202 and the upper plate 201a, and melting the hot-melt adhesive film at a high temperature and then solidifying the molten hot-melt adhesive film at a low temperature.

Different from the conventional honeycomb plate, the area of the honeycomb core layer 201c in the metal honeycomb plate of this embodiment is smaller than the areas of the upper plate body 201a and the lower plate body 201b, and each side edge of the honeycomb core layer 201c is located inside the corresponding side edge of the upper plate body 201a and the lower plate body 201b, so that a floor buckle embedding gap 201d located around the honeycomb core layer 201c is formed between the upper plate body 201a and the lower plate body 201 b. The floor fastener 203 is fitted into the floor fastener fitting gap 201d, and a floor fastener portion fitted into the floor fastener fitting gap 201d is welded and fixed to the upper plate 201a and the lower plate 201 b.

The floor buckle 203 may be welded to only one of the upper plate 201a and the lower plate 201 b. The advantage of so designing lies in: the assembly efficiency of the floor buckle and the metal honeycomb plate is improved. But has the defects that: the connection strength of the floor buckle and the metal honeycomb plate is slightly poor.

Alternatively, an adhesive may be applied to the floor buckle 203, and the floor buckle portion fitted into the floor buckle fitting gap 201d may be fixed to the upper plate 201a or/and the lower plate 201b by the adhesive.

In this embodiment, the metal honeycomb plate is a honeycomb aluminum plate, the upper plate body 201a and the lower plate body 201b are both aluminum plates, and the middle honeycomb core layer 201c is an aluminum honeycomb. Each floor buckle is an integrated part and is made of aluminum profiles. Of course, other materials, such as an integrally formed plastic part, may be used for the floor buckle.

The upper plate body 201a, the lower plate body 201b and the honeycomb core layer 201c in the metal honeycomb plate are made of other materials, such as: the upper plate 201a and the lower plate 201b may also be steel plates, and the middle honeycomb core layer 201c may also be stainless steel honeycomb. In the embodiment, the honeycomb aluminum plate is used as the substrate of the floor block, and the following two considerations are mainly considered:

1. the honeycomb aluminum has mature manufacturing process, lower cost and light weight.

2. The heat conduction rate of the honeycomb aluminum plate is extremely high.

The floor board mainly bears the vertical load from above in the use process, and in order to improve the capability of bearing the vertical load and the vertical impact of the floor board, all the honeycomb holes of the honeycomb core layer 201c of the metal honeycomb board 201 are vertically arranged in a penetrating way in the embodiment, as shown in fig. 2.

If the electric heating film 1 is directly paved on the ground 4 to be in direct contact with the ground 4, a large part of heat of the electric heating film 1 is transmitted to the ground 4 downwards to be lost, based on the above, a layer of heat insulation pad 3 is also paved on the ground 4, the electric heating film 1 is paved on the heat insulation pad 3, the heat transmission path of the electric heating film 1 downwards is separated by the heat insulation pad 3, and most of heat is ensured to be transmitted to the floor block 2 upwards.

The heat insulation pad 3 is preferably made of foam plastic with certain flexibility so as to have protection performance on the electrothermal film 1, and the foam plastic is insulated and insulated, light, environment-friendly and excellent in sound insulation performance.

Further, it is preferable that the heat insulating mat 3 is made of a polystyrene resin (also a foamed plastic) having a fire-proof property.

In order to allow the adjacent floor boards to be connected very conveniently by means of the floor buckles 203 thereon, the present embodiment is provided with one floor buckle 203 on each side of the rectangular metal honeycomb panel 201, so that each floor board is provided with four floor buckles 203. And, two of the floor buckles 203 are male buckles 203a, and the other two floor buckles 203 are female buckles 203b, as shown in fig. 3. When assembling, the male button 203a and the female button 203b of two adjacent floor boards are buckled and connected, as shown in fig. 5.

It should be noted that the two male buckles 203a and the two female buckles 203b on the floor board can be different structures. For example, the floor board disclosed in chinese patent application with publication number CN101910528B, wherein the two long sides are respectively provided with a male buckle and a female buckle which are mutually matched in an angle-tilting manner, and the two short sides are respectively provided with a male buckle and a female buckle which are mutually matched in a vertical displacement manner and have another structure, is obviously not excluded in the claims of the present application.

Example two:

referring to fig. 6 to 10, the floor heating system of this embodiment has substantially the same structure as that of the first embodiment, and the main difference is that in this embodiment, the honeycomb core layer 201c of the metal honeycomb panel 201 adopts another structure, so that the bonding area and bonding strength between the honeycomb core layer 201c and the upper panel body 201a and the lower panel body 201b are improved, and the possibility that the upper panel body and the lower panel body are separated from the honeycomb core layer is specifically as follows:

the honeycomb core layer 201c is formed of a thin metal sheet 201c1 and a plurality of downwardly projecting press protrusions 201c2 which are press-formed on the metal sheet so as to be integrally formed thereon. The upper surface 201c1a of the metal piece 201c1 is in contact with (the lower surface of) the upper plate body 201a and is adhesively fixed thereto, and the lower surface 201c2a of the pressing projection 201c2 is in contact with (the upper surface of) the lower plate body 201b and is adhesively fixed thereto.

In view of the planar structure of the upper surface of the lower plate body 201b, in order to increase the abutting and bonding area of the respective punching protrusions 201c2 with the lower plate body 201b, the present embodiment provides the lower surface 201c2a of each punching protrusion 201c2 as a planar structure, and the lower surface 201c2a of each punching protrusion 201c2 is arranged in the same plane.

Considering that the lower surface of the upper plate body 201a is also of a planar structure, and the lower surface of the upper plate body 201a is parallel to the upper surface of the lower plate body 201b, in order to increase the contact and bonding area of the metal piece 201c1 with the upper plate body 201a, the present embodiment further provides the upper surface 201c1a of the metal piece 201c1 as a planar structure arranged in parallel to the lower surface 201c2a of the stamping protrusion 201c 2.

The sum of the areas of the lower surfaces 201c2a of the stamping protrusions 201c2 is equal to the area of the upper surface 201c1a of the metal sheet 201c1, so that the sum of the adhering areas of all the stamping protrusions 201c2 and the lower plate body 201b is equal to the adhering area of the metal sheet 201c1 and the upper plate body 201a, the total adhering area of the honeycomb core layer is uniformly distributed, the connecting force between the honeycomb core layer 201c and the upper plate body 201a is equal to the connecting force between the honeycomb core layer 201c and the lower plate body 201b, and the bonding force between the plate body on one side and the honeycomb core layer 201c is prevented from being significantly smaller than the bonding force between the plate body on the other side and the honeycomb core layer 201 c.

In this embodiment, the stamping protrusions 201c2 are uniformly distributed in a matrix. Further, each of the punching projections 201c2 has a circular cylindrical shape, and the circular cylindrical punching projection 201c2 has formed therein: a cylindrical groove 201c21 with an open bottom and a closed top, and a circular cylindrical groove 201c22 with an open top and a closed bottom and surrounding the periphery of the cylindrical groove. The upper surface of the top groove wall 201c21a of the cylindrical groove 201c21 is attached to the upper plate body 201a and fixed by bonding, and the lower surface 201c2a of the stamping protrusion 201c2 is formed on the bottom groove wall 201c22a of the circular cylindrical groove 201c 22.

In order to improve the bonding area and bonding strength of the top end groove wall 201c21a of the cylindrical groove and the upper plate body 201a, the present embodiment provides the top end groove wall 201c21a of the cylindrical groove 201c21 as a planar structure, and the upper surface of the top end groove wall 201c21a of the cylindrical groove 201c21 is arranged flush with the upper surface of the metal piece 201c1 — the upper surface of the top end groove wall 201c21a of the cylindrical groove can be regarded as a part of the upper surface of the metal piece 201c 1.

Now, a method for manufacturing the metal honeycomb panel 201c will be briefly described: a plurality of stamping protrusions 201c2 which extend in the same direction along the thickness direction of the metal sheet are stamped on the metal sheet 201c1 (by using a circular cylindrical stamping head), then the upper surface 201c1a of the metal sheet 201c1 is abutted against and bonded to the upper plate body 201a, and the lower surface 201c2a of each stamping protrusion 201c2 is abutted against and bonded to the lower plate body 201 b.

In this embodiment, the cylindrical groove 201c22 has a radial width gradually decreasing from the notch toward the groove bottom to facilitate the demolding of the press mold.

The metal sheet 201c1 is preferably an aluminum sheet having good ductility, and the thickness thereof is generally selected to be 0.02 to 1 mm. Example three:

fig. 11 and 12 show a further particular embodiment of the floor panel of the present application, which is substantially identical in structure to the second embodiment, with the only difference that: the outer contour of each punch protrusion 201c2 in the honeycomb core layer is cylindrical.

Obviously, the punching protrusion 201c2 may have other shapes, such as a polygonal prism shape.

However, it is preferable to arrange the punching protrusions 201c2 in the shape of the circular column of the second embodiment, so that the number of the vertical supporting arms between the upper and lower plate bodies can be increased, and the bearing strength of the honeycomb panel can be increased.

The above are exemplary embodiments of the present application only, and are not intended to limit the scope of the present application, which is defined by the appended claims.
