Description

Technical Field

[0001] The present invention discloses an electric heating brick including an electric heating wire, and more particularly relates to a block-shaped electric heating brick, in which a temperature sensor and an electric heating wire are arranged, so that a user can monitor the temperature of the brick and control the heating of the electric heating wire. Background Art

[0002] Generally, in order to decorate a specific space, plate-shaped interior materials such as tiles, wood, metal, and synthetic resin are attached to the inner walls of a building.

[0003] Most of these interior materials in buildings have the problem of being heavy and are only used as interior materials that have a beautiful appearance but are not very functional.

[0004] There are two types of indoor heating in buildings: forced air heating, which uses electric heaters or burning fuels such as natural gas to heat cool air and blow it into the room; and radiant heating, which heats the floors or walls, warming the room by radiation from the floors or walls.

[0005] It is particularly pointed out here that radiant heating is mainly used because it has better heating efficiency. This radiant heating is divided into heating that heats the floor or wall by guiding hot water in pipes under the floor or behind the wall, heating that heats the floor or wall by embedding electric heating wires in the floor or wall, etc.

[0006] However, when using hot water radiant heating, water leakage may occur due to rotting or cracking of pipes, so hot water heating has gradually been replaced by heating with electric heating wires.

[0007] However, the use of electric heating wires for heating also has the problem of requiring a lot of labor and construction costs, because it involves a series of complicated procedures: laying the electric heating wires under the floor or behind the wall, then pouring cement on it, laying additional tiles for decoration or covering the surface, and fixing them on the hardened and dried cement, etc. In addition, in the case of using electric heating wires for heating, a large amount of electromagnetic waves that are harmful to the human body are generated.

[0008] In order to solve such problems, people began to use flat heating elements or linear heating elements for floor heating, which generate fewer electromagnetic waves and are easy to transfer heat.

[0009] Specifically, for the construction of floor heating using flat heating elements, an insulating material is laid on the floor to be heated and the flat heating elements are applied thereon.

[0010] However, the flat heating element is weak in strength and is easily damaged by external impact, and has weak moisture resistance and is prone to fire due to short circuit. In addition, when some flat heating elements are damaged, it is difficult to repair them.

[0011] Meanwhile, US Patent Application Publication No. US2004 / 0109681 discloses a modular electric heating tile, comprising a tile body and an electric heating unit. The tile body is made of a material selected from clay and cement, and has two opposite first and second surfaces. The electric heating unit is installed on the tile body adjacent to the first surface in an encapsulated manner.

[0012] However, in the case of conventional technology, since heating wires and heat-conducting bricks are used as heating media, it is difficult to ensure sufficient connection area between the two, which may result in poor heat transfer, possible short circuit of the heating wire, etc., which not only reduces functionality but also reduces safety.

[0013] Furthermore, in order to insert the heating wire into the block base, a heating wire installation groove and a cavity must be machined on the surface of the block base before installing the heating wire, which is disadvantageous in terms of manufacturing capability.

[0014] Therefore, in order to solve the above problems, it is necessary to study heating bricks that are easy to construct and maintain and can be safely used in accidents such as fires. Summary of the invention

[0015] The object of the present invention is to provide an electric heating brick, which is in the form of a ceramic module with a built-in electric heating wire, and one side of which includes a fastening component, so that it is easy to couple with each other and simple to install.

[0016] Furthermore, the present invention aims to provide an electric heating brick, which comprises a control module connected thereto, for collecting temperature data from a temperature sensor placed therein, and controlling the heating of the heating wire in a safe and simple manner based on the temperature data.

[0035] Embodiment 1

[0036] See also Figures 1 to 3 The electric heating brick 100 of the embodiment of the present invention may include at least one temperature sensor 111; a first layer 110, on which a power line 112 electrically connected to the temperature sensor 111 is arranged; a second layer 120, which is arranged on the upper surface of the first layer 110 and is provided with a heating wire 121 electrically connected to the power line 112; an upper cover 130 covering the upper surface of the second layer 120; and a lower cover 140 covering the lower surface of the first layer 110.

[0037] For example, the upper cover 130 may be made of various materials such as ceramics, wood, synthetic resin, etc., and the lower cover may be made of synthetic resin such as PVC.

[0038] For example, the thickness of the air gap formed between the first layer 110 and the upper cover 130 may be less than a preset maximum thickness (eg, 10 mm).

[0039] Also, see Figure 4 , the lower cover 140 may have at least one fastening member 141 on one side thereof, and the fastening member 141 is electrically connected to the power line 112 formed on the first layer 110 .

[0040] like Figure 5As shown, the electric heating bricks 100 can be connected to each other by fastening members 141. That is, since the electric heating bricks 100 can be in a modular form for easy assembly, the electric heating bricks 100 can be placed not only in the entire area but also in a local area where construction is required.

[0041] Also, see Figure 6 and Figure 7 The electric heating brick 100 may further include a control module 150 for controlling the heating of the electric heating wire.

[0042] The lower cover 140 may include a cable 142 , one end of the cable 142 being connected to the fastening member 141 , and the other end of the cable 142 being connected to the control module 150 .

[0043] For example, a groove for inserting the cable 142 may be formed in a region of the lower cover 140 where the fixing member 141 is located.

[0044] Therefore, after the electric heating bricks 100 are coupled to each other, the cable 142 can be pulled out from any one of the electric heating bricks 100 and connected to the control module 150 .

[0045] At the same time, the control module 150 may include a power supply unit 151 for supplying power to the temperature sensor 111 and the power line 112, a communication unit 152 for receiving a user control signal from a predetermined user terminal, and a heating wire control unit 153 for controlling the heating of the heating wire 121 based on the user control signal received from the communication unit 152.

[0046] For example, the user's control signal may include information about a heating reservation time, a maximum heating temperature, a minimum heating temperature, and the like.

[0047] Therefore, the heating wire control unit 153 may control the heating of the heating wire 121 by adjusting the level based on the user's control signal, and the control module 150 may control the voltage applied to the heating wire 121 , the duty cycle, and the like.

[0048] Meanwhile, the first layer 110 may further include a communication tag (not shown), and the control module 150 may further include a tag identification unit (not shown) for identifying the communication tag.

[0049] More specifically, the tag identification unit may include a code assignment unit that assigns a unique sequence to the communication tags when at least two communication tags are identified; and a temperature collection unit that collects temperature data from the temperature sensor based on the unique sequence.

[0050] Therefore, when multiple heating tiles 100 are combined together, the tag identification unit can identify each of the multiple heating tiles 100, and can assign a unique sequence to the communication tags contained in the heating tiles 100, so that the temperature of each of the multiple heating tiles 100 can be monitored.

[0051] For example, when four electric heating tiles 100 are arranged, the control module 150 may identify each electric heating tile 100 through a communication tag included in the electric heating tile 100. In this case, the heating condition of each electric heating tile 100 may be monitored.

[0052] Therefore, it is possible to monitor whether the temperature sensor 111 and the heating wire 121 included in each electric heating brick 100 have an error, and it is possible to monitor whether an electric heating brick 100 has an error. If an error occurs, it needs to be replaced quickly.

[0053] At the same time, if Figure 8 As shown, the second layer 120 may include a first terminal 1211 arranged at one end of the heating wire 121, which is located at a position corresponding to the position of the positive electrode 1121 set on the first layer 110, and the second layer 120 also includes a second terminal 1212 arranged at the other end of the heating wire 121, and its position corresponds to the position of the negative terminal 1122 set on the first layer 110.

[0054] In this case, in order to electrically connect the first layer 110 and the second layer 120, the first terminal 1211 and the second terminal 1212 may be connected to the positive terminal 1121 and the negative terminal 1122, respectively, by welding, and a conductive paste may be applied to the welding region.

[0055] For another example, a heat conducting sheet may be attached to the side of the upper cover 130 so that when a plurality of electric heating bricks 100 are combined, heat can be quickly conducted between the electric heating bricks 100 .

[0056] Embodiment 2

[0057] Meanwhile, in order to determine whether the noise is generated due to foreign matter attached to the temperature sensor 111, etc., the control module 150 may further include a sensor error monitoring unit (not shown) which receives and analyzes the collected data from the temperature sensor.

[0058] In other words, when foreign matter is attached to the surface of the temperature sensor, the value measured by the sensor will show an irregular pattern. In this regard, considering these characteristics, it is possible to determine not only whether foreign matter is attached to the surface of the sensor, but also whether an error has occurred in the operation of the sensor.

[0059] To this end, the sensor error monitoring unit (not shown) may calculate an average value and a standard deviation of a plurality of values ​​measured by the sensor within a preset time period. When the number of values ​​other than the average standard deviation of the plurality of values ​​(hereinafter referred to as "noise data") is equal to or greater than a preset number (e.g., 5), the sensor error monitoring unit (not shown) may assume that a foreign object is attached to the surface of the sensor.

[0060] Meanwhile, a sensor error monitoring unit (not shown) may calculate an interval between times when each noise data is measured, and may determine that foreign matter is attached to the surface of the sensor when the interval is not constant.

[0061] Here, when the maximum difference (M) between the time intervals of the noise data is calculated according to the following formula 1 d ) is equal to or greater than the average value (T av ) is multiplied by a constant (e.g., Formula 2) to calculate the value, it cannot be determined that the time interval is a constant.

[0062] M d =N max -N min

[0063] ------------------Formula 1

[0064] Among them, M d is the maximum difference in the time interval between noise data, N max is the maximum time interval between noise data, N min is the minimum time interval between noise data.

[0065]

[0066] Where T av is the average value of the noise data time interval, T (i-1)to i is the time interval between the i-1th noise data and the i-th noise data, T 0 to 1 is the time interval between the start of the sensor operation and the first noise data appearance, and n is the number of noise data.

[0067] For example, as shown in Table 1, when T0 to T 20 When the data is 9, 10, 11, 12, 14, 18, 9, 9, 6, 13, 2, 8, 9, 9, 10, 17, 9, 10, 3, and 12, the average value is 10 and the standard deviation is 3.88. Therefore, there are 6 annotation data: 14, 18, 6, 2, 17, and 3. Since the amount of noise is greater than the preset value of 5, it can be inferred that there is foreign matter attached to the sensor surface.

[0068]

[0069] Table 1

[0070] The results of calculating whether the noise is irregular according to Formula 1 and Formula 2 are as follows: As shown in Table 2, the maximum difference between the time intervals of the noise data (M d) is seven, that is, eight minus one, the average value of the time interval between noise data (T av ) is 3.5.

[0071] <![CDATA[Noise data (T (i-1)to i )]]> <![CDATA[T 01 ]]> <![CDATA[T 12 ]]> <![CDATA[T 21 ]]> <![CDATA[T 34 ]]> <![CDATA[T 45 ]]> <![CDATA[T 56 ]]> <![CDATA[T avg ]]> The time interval between noise data 5 1 3 2 8 2 3.5

[0072] Table 2

[0073] Therefore, due to the maximum difference in the time interval between the noise data (M d )7The average value of the time interval between the noise data (T av ) is within the range of twice or more of 3.5, so it can be confirmed that foreign matter is attached to the sensor surface.

[0074] As described above, according to the embodiments of the present invention, errors caused by foreign matter attached to the sensor surface can be monitored and sensed by the sensor error monitoring unit, so that it can be determined more accurately whether the temperature sensor operates normally.

[0075] The electric heating brick according to the present invention may be in the form of a ceramic module with a built-in heating wire, and include a fastening member on one side so as to be mounted in a simple manner by being easily coupled to each other.

[0076] Furthermore, the electric heating brick according to the present invention may include a control module connected thereto so as to collect temperature data from a temperature sensor disposed therein and control the heating of the heating wire in a safe and simple manner based on the temperature data.

[0077] In addition, the method for controlling electric heating bricks according to an embodiment of the present invention can be recorded on a computer-readable medium, which includes program commands for performing various operations that can be performed by a computer. The computer-readable medium may include program commands, data files, data structures, etc. alone, or may include a combination thereof. The program commands of the medium may be specially designed and constructed for the present invention, or may be widely known to ordinary technicians in the field of computer software. Examples of computer-readable recording media may include magnetic media, such as hard disks, floppy disks and tapes, optical media, such as CD-ROMs and DVDs, magneto-optical media, such as optical discs, and hardware devices specially designed for storing and executing program commands, such as ROM, RAM, and flash memory. Examples of program commands may include not only machine language codes, such as machine language codes created by compilers, but also high-level language codes that can be executed by computers using interpreters, etc.
