Description

Title: PREFABRICATED HEATING MAT PANEL AND ASSEMBLY THEREOF
Technical Field The present invention relates to a prefabricated heating mat panel and an assembly thereof, and in particular to a prefabricated heating mat panel and an assembly thereof which are prefabricated and installed on a floor or a wall of a building for the purpose of heating.
Background Art
In recent years, a prefabricated heating mat panel or warming panel is widely used for the purposes of heating and warming by using electric power, an energy source.
The heating panel is manufactured with various standard sizes in a construction that a heat coil, which acts as a heating member, is arranged on a rigid adiabatic panel. So, multiple heating panels classified by standards corresponding to a construction surface area are needed, and an adiabatic panel with the same thickness as the heating panel is fitted in a non-standard size gap portion which cannot be fitted with a standard size product. The conventional heating panel using a heat coil has lower heat transfer efficiency and disadvantageously needs a lot of time for a heating construction. The manufacturing and transportation costs needed for manufacturing various size standard products are too high. The heating panel using a heat coil disadvantageously generates a lot of electromagnetic waves, which may hurt a user's health. So, the use of the conventional heating panel gradually decreases.
In order to overcome the problems founded in the conventional heating panel that uses a heat coil, a film-shaped heater able to emit far infrared radiation has been developed and has been widely used. Here, the film heater is manufactured in such a manner that high resistance material carbons or carbon particles are coated on a film sheet (PET film), with a thin copper line being formed at both ends of the same, which acts as an electrode. In the film heater, a more amount of uniform heat is generated as compared to the conventional heat coil-based heating panel, and as far infrared radiation is radiated, radiation heat is generated. Consequently, electricity rate can be saved, and electromagnetic waves are less generated. Excellent flat-structure work and excellent product durability are obtained.
Adiabatic materials are bonded on a floor surface of a building during a heating construction by using a conventional film heater. A roll type film heater is cut and arranged in multiple blocks on the adiabatic material over a floor surface of a certain building. A compression terminal is engaged at an electrode of both ends of the film heater, which is divided into each block, or is soldered by using a connection line. The same polarities of the connection lines connected to each film heater are collected and connected. The engaged portion of each connection line is insulated and connected in parallel with a power line of a thermometer. After a normal operation state is checked, a non- woven fabric or an insulation sheet is arranged on an upper side of the film heater, and a floor finishing material is bonded, and the construction is then finished. Multiple construction processes are needed for a heating construction by using a film heater, and multiple work processes are performed for connecting the power with the heat coils of the thermometer. Connecting the power with connection lines is poorly performed, some problems occur due to the failure in the connections. Since the construction is relatively complicated and hard, the construction of the film heater should be performed by an expert. Consequently the construction for a film heater becomes too expensive. The film heater is generally manufactured in the same patterns with a length of a few tens of meters in a roll shape. When it is actually constructed, the allowable current capacity of the electrodes of the film heater (the maximum allowable current of the electrodes of a common film heater is above 10A) may be limited, so the total extendable length of the film heater product is limited. If the film heater is constructed with over allowable current capacity, over load could occur in the electrodes of the film heater, so that the heating becomes non-uniform, and the life span of the film heater becomes shorter. In case of the heating construction by using a conventional prefabricated heating panel or film heater, the heating panel or film heater is connected in a parallel structure over a plurality of power lines divided from the thermometer, namely, it is constructed in a trapezoid shape parallel structure. Part of the prefabricated heating panel or part of the electrodes (electrode power line) of the film heater may be hurt, so the power lines connected in parallel in a trapezoid shape may become short-circuited. In this case, the power cannot be supplied to the short-circuited portions in the above parallel- connected heating panel or film heater.
In the disclosed conventional arts, Figure 9A is a view illustrating a line layout state of a conventional heating electric panel disposed in the Korean utility model registration number 0248945, and Figure 9B is a view illustrating the equivalent construction of Figure 9A, and Figure 9C is a plane view illustrating an installation state of another conventional Korean under-floor heating system panel disclosed in the Korean utility model registration number 0261676.
In the Korean utility model registration number 0248945 of Figure 9A, the prefabricating construction of the heating electric panel 1a is disclosed. As shown in Figure 9B, a plurality of heating units 5a are connected in parallel in a trapezoid shape with power lines 2a and 3a divided and extended from the power source. As shown in Figure 9C of the Korean utility model registration number 0261676, a plurality of heating units 5b are connected in parallel with the power lines 2b and 3b in a trapezoid shape.
In the conventional heating panels shown in Figures 9A through 9C, when a short circuit occurs in an X-shape on the power lines as shown in Figure 9B, all the portions connected in parallel in a trapezoid shape below the short- circuit power lines are affected, so that the heating operation is stopped.

So, the power line connection unit 13c may be formed at the portion in which the connection and crossing- insulation are made.
As shown in Figure 3, the insulation sheet 32c may be disposed on the film heater 34, and the aluminum thin plate 35 may be disposed on the insulation sheet 32c. The aluminum thin plate 35 is provided for preventing electromagnetic waves from the film heater 34 and the power line sheet 33. The material of the same is not limited to aluminum. A certain material having the same operations and effects may be used. Figure 4 is a view illustrating the above construction.

The fixing terminal 21 is exposed on the power line connection units 13a and 13b and forms parts of the power line connection units 13a and 13b. When the power connection units 24 and 25 provided for connecting the terminals of the power line connection units 13a and 13b with another neighboring heating mat are engaged with the power line connection units 13a and 13b, the fixing protrusions 26 formed in the power connection units 24 and 25 are inserted into the fixing terminal 21 , respectively, so that multiple heating mat panels 10 arranged closer to one another can be reliably fixed. At this time, the fixing protrusion 26 and the fixing terminal 21 electrically connect multiple aluminum thin plates 35 for thereby forming a large size electromagnetic wave shielding curtain. Figure 4 shows the above construction. In the embodiment of Figure 4, a non-woven fabric 36 may be disposed on the aluminum thin plate 35, and a finishing material 37 may be disposed on the non-woven fabric 36.

The reference numeral 40 corresponding to a construction formed of the insulation sheet 32c and the film heater 34 may be formed in one sheet structure. The film heater 34 and the power line sheet 33 should be insulated from each other. So, it is possible to decrease the number of sheets which form the heating mat panel 10, and the thickness of the heating mat panel 10 can be significantly decreased. The film heater 34 and the power line sheet 33 may be insulated except the connected (disconnected) portions in the first and second electrode power lines 11 and 12 and may be formed in one sheet structure.

As shown in Figures 5A through 5C, the insulation cross type connection unit 13b is crossed (N) since the second electrode power line 12b of the power line sheet 33 and the first electrode power line 11a of the film heater 34 have different polarities, and the first electrode power unit 11b of the power line sheet 33 and the second electrode power line 12a of the film heater 34 have different polarities, and the first and second terminals 18 and 19 are insulated. In the electrode common type connection unit 13a, since the second electrode power line 12a of the film heater 34 and the first electrode power line 11b of the power line sheet 33 have the same polarities, and the first electrode power line 11a of the film heater 34 and the first electrode power line 11b of the power line sheet 33 have the same polarities, the first terminal 18 and the second terminal 19 are connected by means of the cross point P. As shown in Figure 3, a triangle shaped connection member cover 22 is disposed at each corner of the hearing mat panel 10. The connection unit cover 22 covers the power line connection units 13a and 13b of the neighboring heating mat panel 10 for protecting the same. The connection unit cover 2 is made of the same material as the finishing material 37, so it may operate as a corner surface role of the finishing material 37. The rectangular connection member cover may be disposed as shown in Figure 4.
Figure 7A is a schematic view illustrating a power connection unit in a prefabricated heating mat assembly according to another embodiment of the present invention, and Figure 7B is a schematic view illustrating another power connection unit in a prefabricated heating mat assembly according to another embodiment of the present invention.
Namely, there are shown the power connection units 24 and 25 which connect the power line connection units 13a and 13b of the neighboring heating mat panel 10. The power connection unit 24' of Figure 6B is different from the power connection unit 24 of Figure 7A in their shapes. It can be easily recognized with reference to the construction of the power line connection unit 13d of Figure 6A, so the construction will be described with reference to Figures 7A and 7B. The power connection units 24 and 25 is formed of a first power connection unit 24 which connects the power line connection units 13a and 13b of the portion A of Figures 5A and 5B and a second power connection unit 25 which connects the power line connection units 13a and 13b of two neighboring heating mat panels 10.
The first power connection unit 24 is formed in a rectangular shape, and four fixing protrusions 26 inserted into the fixing terminals 21 are disposed at an inner side. The fixing protrusions 26 are provided for fixing four neighboring heating mat panels 10.
The four fixing protrusions 26 are connected with each other by means of a conduction material and are disposed closer to one another, so the aluminum thin plates 35 of four heating mat panels 10 connected by means of the first power connection unit 24 are electrically connected. The aluminum thin plate 35 of the heating mat panels 10 connected in all the directions are grounded to a grounding portion of one end of the heating mat panel block for thereby shielding the electromagnetic waves from the film heater 34.
Four connection terminals 27 are disposed at an outer side of the fixing protrusion 26. Two connection protrusions 27a inserted into the first terminal 18 or the second terminal 19 are provided in each connection terminal 27. Each connection terminal 27 connects two neighboring first terminals 18 or connects two neighboring terminals 19.
As shown in the portion A of Figures 5A and 5B, in case of the power connection unit 24 which connects four heating mat panels 10, one power line connection unit and two different power line connection units contacting with its side, respectively, are formed of different power line connection units 13a and 13b. Four power line connection units, which contact with one another, are provided with the power line connection units 13a and 13b of the same shapes in diagonal directions, and the cross point (P) is formed in a diagonal direction. As shown in Figure 6a, in the power line connection units 13c and 13d of the rectangular power connection unit 24 which connects four heating mat panels 10, the same power line connection units 13c and 13d are connected with the terminals having the same polarities. As shown in the portion B of Figure 5B which shows the power connection units of four neighboring power line connection units, the power line connection units 13a and 13b are disposed in the same side, not in a diagonal direction. So, the cross point (P) can be disposed in the same side, not in a diagonal direction. The first power connection unit 24 covers both the power line connection units 13a and 13b of the four heating mat panels 10 which are closet to one another, so that the four neighboring heating mat panels 10 can be electrically connected in parallel.
The second power connection unit 25 is formed in a triangle shape and includes one connection terminal 27, which consists of two fixing protrusions 26 and two connection protrusions 27a. The second power connection unit 25 connects the electrode power lines of the power line connection units 13a and 13b of two neighboring heating mat panels 10.
Here, the first and second power connection units 24 and 25 may be provided separately from the heating mat panel 10. As shown in Figure 6B, it may include the power connection units 24 and 24', and as shown in Figure 6A, the power connection units 24 and 24' of Figure 6B may be easily understood from the constructions of the first and second power connection units 24 and 25 of Figures 7A and 7B. Figures 5A through 5C are views illustrating a prefabricated structure of a prefabricated heating mat assembly according to another embodiment of the present invention, Figure 5D is a perspective view illustrating a construction state of a prefabricated heating mat assembly according to another embodiment of the present invention, and Figures 6A and 6B are views illustrating a prefabricated structure of a prefabricated heating mat assembly according to another embodiment of the present invention.
As shown in Figure 6B, nine heating mat panels 10 are arranged so that the heat coils 14a are arranged in a combination with the same directions and the vertical directions. A lower part of the prefabricated heating mat panel 10 is cut depending on the surface area of the construction site. Here, the symbol C represents a cutting line, and C represents another cutting line. The heating mat panels 10 according to an embodiment of the present invention are stacked and bonded with one another, and all the stacked sheets can be easily cut. Since the heating mat panel 10 is substantially thin, it is possible to easily cut the same with scissors or knife. The cut portions are insulated by means of an insulation tape. The construction of Figure 5B may be implemented in a combination with the heating mat panels of Figure 6A.
Figure 5C is a view illustrating a construction that the power connection units 24 and 25 are installed in the heating mat panel 10 of Figure 5A. For easier understanding, an outer construction and an inner construction are concurrently shown. The first rectangular power connection unit 24 is installed at a portion in which four heating mat panels 10 meet with one another, and the triangle second power connection unit 25 is installed at an edge in which two heating mat panels 10 meet with each other. A cable integral power connection unit is connected with a connection part of the temperature adjuster 50 as shown in Figure 5B.
In a state that the heating mat panel 10 is prefabricated as shown in Figures 5B and 5C or part of the same is disconnected, the power is supplied to the whole structure since the first and second electrode power lines 11a and 12a of the film heater 34 and the first and second electrode power lines 11b and 12b of the power line sheet 33 are formed in a lattice shape in the power line connection units 13a and 13b provided at a part of the heating mat panel 10 and are connected by means of the cross point P. When it is needed to heat a relatively larger surface area, the power lines connected with the heating mat panels 10 are connected with the temperature adjuster connection unit having the same polarities, and then the same power is concurrently supplied. So, a lattice type power circuit is formed in the whole prefabricated heating mat panels 10. So, the prefabricated heating mat panels 10 are heated uniformly all the time, and it is possible to prevent the life span from being shortened due to the short circuit of electrodes or overloads.
Figure 5C shows a prefabricated construction of the heating mat panel 10. The triangle second power connection member 25 is used depending on the construction site and condition. The power supply of the heating mat panel 10 is divided from one source and is inputted into a corresponding mat. Figure 5C concurrently shows an outer construction and inner construction for easier understanding.
As shown in Figure 5C, the cable divide power connection unit is installed in the heating mat panel 10 near the temperature adjuster connection unit after the power can be divided and inputted into the prefabricated heating mat panel 10. The connection lines having the same polarities are connected to the cables of the temperature adjuster connection unit, and the triangle second power connection unit 25 is engage for a power connection of the arranged heating mat panels 10, and the heat mat panels are expanded in a straight line shape by the area needed. The cable divide power connection unit has the same structure as or similar with the triangle second power connection unit 25, and is engaged to the power line connection units 13a and 13b of the heating mat panel with a cable being engaged to a circular terminal.
During the construction of the heating mat panel 10 according to the present invention, variously modified connection methods may be used. The prefabricated heating mat panel according to an embodiment of the present invention can be applied to a floor as well as wall or a ceiling of a building for the purpose of heating. In case that the heating mat panel 10 is constructed on a wall surface or a ceiling, a certain engaging unit is needed in the heating mat panel 10 for stably fixing the heating mat panel 10 on a wall surface or a ceiling by using a bolt, screw or protrusion.
