Description

Technical Field

[0001] The present invention relates to an intelligent electric heating brick containing a copper tube. More specifically, the electric heating brick is internally installed with a layer of copper tube and copper film. Heat is dissipated from the upper surface of the intelligent brick through a heating cable inserted into the copper tube. Background Art

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

[0003] Most of these interior materials in buildings have the problem of being heavy and are only used as simple building interior decoration materials with beautiful appearance but poor functionality.

[0004] Meanwhile, indoor heating in buildings comes in two varieties: forced-air heating, which uses electric heaters or fuels like natural gas to heat cool air and blow it into the room; and radiant heating, which heats the floors or walls, warming the room through heat radiation from the floors or walls.

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

[0006] Among them, hot water heating is gradually being replaced by electric heating line heating due to the risk of water leakage when pipes are rotten or damaged.

[0007] However, even electric heating lines require a complex construction process. Before laying the floor or walls, the heating lines must be laid, cement is poured, and after the cement hardens and dries, decorative or other surface tiles are laid and secured on top. Furthermore, electric heating lines have drawbacks such as requiring a large amount of labor, high construction costs, and generating a large amount of electromagnetic waves that are harmful to the human body.

[0008] In order to compensate for these disadvantages, floor heating using flat-shaped heating elements or linear heating elements, which generate less electromagnetic waves and easily transfer heat, is being used.

[0009] Specifically, in the construction of floor heating using flat-shaped heating elements, 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 easily damaged by external impact, and has weak moisture resistance and is prone to fire caused by short circuit. In addition, when some flat heating elements are damaged, it is difficult to repair them.

[0011] Meanwhile, Korean Patent Publication No. 10-2015-0099894 describes a heating module structure in which a square block base is formed with a cover mounting groove and an electric heating wire mounting groove, the upper surface of which is coated with a thermal conductive solution or thermal paste, the electric heating wire is inserted into the electric heating wire mounting groove, and the covered mounting groove is covered with a cover.

[0012] However, in the prior art, since electric heating wires and thermally conductive solutions (or thermally conductive pastes) are used as heating media, it is difficult to ensure that there is sufficient connection area between the two, resulting in problems such as poor connection and sparks, which not only reduces functionality but also reduces safety.

[0013] Furthermore, in order to insert the electric heating wire into the block base, it is necessary to machine an electric heating wire installation groove on the upper surface of the block base before installing the electric heating wire, which has disadvantages in terms of manufacturability and workability.

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

[0015] This disclosure section is provided to briefly introduce concepts that will be described in detail in the detailed description section below. This disclosure section is not intended to identify key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0016] The purpose of the present invention is to provide an intelligent electric heating brick, in which a copper tube made of copper and a copper film formed above the copper tube are arranged inside the brick. By inserting a heating cable (such as an electric heating wire) into the copper tube, the heat generated by the heating cable can be more easily dissipated from the upper surface of the brick.

[0017] Furthermore, the present invention discloses an object to provide an electric heating brick that can be conveniently installed and maintained through magnet coupling by providing at least one magnetic component on a side surface.

[0018] In addition, the purpose of the present invention is to provide an electric heating brick, and by including a control module electrically connected to the electric heating brick, the temperature of the copper tube is measured and the heating state of the electric heating brick is safely controlled.

[0025] According to the present invention, a copper tube and a copper film are provided inside the electric heating brick, wherein the copper tube is made of copper. A heating cable (e.g., an electric heating wire) is provided which is inserted into the copper tube and passes through the upper surface of the brick. Heat generated by the heating cable can be more easily dissipated from the upper surface of the brick.

[0027] In addition, the electric heating brick includes a control module electrically connected thereto, through which the temperature of the copper tube can be measured and the heating state of the electric heating brick can be safely controlled. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] <Example 1>

[0042] See also Figure 1 , Figure 2 , Figure 3 ,and Figure 4 According to the embodiment disclosed in the present invention, the electric heating brick 100 may include: a first layer 110, on which a copper tube 111 is provided; a second layer 120, which is provided on the first layer 110 and is patterned by at least one copper film 121; a top cover 130, which covers the upper surface of the second layer 120; and a bottom cover 140, which covers the lower surface of the first layer 110.

[0043] For example, the top cover 130 may be made of various materials such as ceramics, wood, synthetic resin, etc., and the bottom cover may be made of synthetic resin materials such as PVC.

[0044] For example, the air gap between the first layer 110 and the top cover 130 may be smaller than a preset maximum thickness (eg, 10 mm).

[0045] For another example, the patterning of the copper film 121 may be determined corresponding to the size and shape of the top cover 130 .

[0046] Also, see Figure 5 , the top cover 130 and the bottom cover 140 may be provided with at least one magnetic component 131 and a magnetic component 141 on one side surface.

[0047] Therefore, the electric heating brick 100 can be modularly combined through the magnetic component 131 and the magnetic component 141, and the electric heating brick 100 can be placed in the entire construction area or in a local area where construction is required.

[0048] Also, see Figure 6 and Figure 7 The bottom cover 140 may include a first inlet 142 provided on one side surface, a second inlet 143 provided on the other side surface facing the first inlet 142 , and an inserter 144 inserted into the first inlet 142 and the second inlet 143 .

[0049] At this time, the insert 144 is made of elastic material and is configured in a tubular shape. A through hole is provided inside the insert 144 , and the copper tube 111 can be inserted into the through hole.

[0050] Preferably, the insert 144 may be made of a silicone material.

[0051] Therefore, both ends of the copper tube 111 disposed in the first layer 110 can be protected by the insert 144 , and movement of the copper tube 111 can be minimized.

[0052] In this case, the heating cable 10 may be inserted into the copper tube 111 , and heat generated by the heating cable 10 may be transferred to the top cover 130 through the copper tube 111 of the first layer 110 and the copper film 121 of the second layer 120 .

[0053] At the same time, if Figure 8 As shown, the electric heating brick 100 may further include a control module 150 , and the control module 150 is used to control the heating state of the copper tube 111 .

[0054] More specifically, the control module 150 may include a temperature sensor 151 for measuring the temperature of the top cover 130, a power supply unit 152 for supplying power to the heating cable 10 inserted into the copper tube 111, a communication unit 153 for receiving a user control signal from a predetermined user terminal, and a temperature control unit 154, which controls the heating temperature of the copper tube 111 based on the user control signal received from the communication unit 153.

[0055] For example, the user control signal may include a heating reserve time, a maximum heating temperature, a minimum heating temperature, and the like.

[0056] Therefore, the temperature control unit 154 may control the heating state of the heating cable 10 by adjusting the magnitude and duty ratio of the voltage applied to the heating cable 10 based on the user control signal.

[0057] Meanwhile, the copper tube 111 of the first layer 110 is made of the same material as the copper film 121 of the second layer 120 , and the copper tube 111 and the copper film 121 may be connected by welding.

[0058] In addition, epoxy resin is coated in an area of ​​the bottom cover 140 where the first layer 110 is mounted.

[0059] More specifically, epoxy resin or the like may be coated on the inner surface of the bottom cover 140 with a preset thickness (eg, 10 mm), and heat generated from the lower surface of the bottom cover 140 may be blocked by the epoxy resin.

[0060] That is, by coating epoxy resin or the like on the inner surface of the bottom cover 140, the temperature of the copper tube 111 and the copper film 121 can be prevented from being affected by the heat rising from the bottom of the bottom cover 140, and the heat generated by the heating cable 10 inserted into the inside of the copper tube 111 can be released through the top cover 130.

[0061] Furthermore, when the heating temperature of the copper pipe is input using the control module 150 , heat loss due to cold floor air or the like can be minimized.

[0062] At the same time, if Figure 9 As shown, the electric heating brick may further include a side cover 160 , which has the same thickness as the total thickness of the bottom cover 140 and the top cover 130 , has a cavity inside, and has at least one through hole on one side surface.

[0063] The heating cable 10 passing through the first inlet 142 and the second inlet 143 of the bottom cover 140 may pass through an insertion through-hole provided in the side cover 160 .

[0064] In other words, as long as the side cover 160 is arranged along the outer edge of the heating area of ​​the electric heating brick 100, the construction of the brick can be completed.

[0065] At this time, the side cover 160 may include at least one cutting line in the horizontal and vertical directions, and the side cover 160 may be cut according to the shape of the floor.

[0066] For example, the side cover 160 may be made of plastic.

[0067] For another example, a heat conducting sheet is attached to the side of the top cover 130 so as to form a rapid heat conduction between the electric heating bricks 100 when a plurality of electric heating bricks 100 are combined.

[0068] <Example 2>

[0069] Meanwhile, the control module 150 may further include a fault diagnosis unit (not shown) that analyzes temperature data (sensor output data) collected by the temperature sensor 151 .

[0070] The fault diagnosis unit (not shown) may analyze the sensor output data in real time and determine that a fault has occurred in the temperature sensor 151 when an instantaneous rate of change of the sensor output data is equal to or greater than a preset value.

[0071] To this end, in embodiment 1, the instantaneous change rate Rchange of the sensor output data is calculated. When the instantaneous change rate Rchange is greater than the preset limit value Serr, it can be determined that an error has occurred in the real-time output data of the sensor (for example, due to a fault in the sensor itself).

[0072] The instantaneous change rate Rchange of the sensor output data can be calculated by the differential value f'(x) of the function f(x) representing the sensor characteristics, as shown in the following [Mathematical Expression 1].

[0073] [Mathematical expression 1]

[0074]

[0075] Here, Rchange represents the instantaneous rate of change of the sensor output data, and t represents the time change.

[0076] In the second embodiment, a sensor failure is determined only when the sensor instantaneous rate of change calculated in [Mathematical Expression 1] exceeds the preset limit value Serr a number of times equal to or greater than a preset number of times within a preset time period. In other words, since it is difficult to determine a sensor failure in the case of a one-time high instantaneous rate of change, to improve the accuracy of sensor failure determination, a standard can be set such that a sensor failure is determined only when the number of failures exceeds a preset number within a preset time period.

[0077] In the third embodiment, a sensor failure is determined only when the cumulative number of sensor instantaneous rate changes calculated in [Mathematical Expression 1] exceeds a preset limit value Serr by a predetermined number of times. Similar to the second embodiment, since it is difficult to determine a sensor failure in a one-time event with a high instantaneous rate, a standard can be set to improve the accuracy of sensor failure determination, such that a sensor failure is determined only when the number of failures exceeds a predetermined number within a predetermined time period.

[0078] In the fourth embodiment, when the instantaneous change rate of the sensor calculated in [Mathematical Expression 1] changes rapidly, it can be determined that the sensor is faulty.

[0079] To this end, f'(x) calculated in [Mathematical Expression 1] is differentiated again to calculate f"(x). When the calculated value is greater than a preset value, it can be determined that the sensor is faulty.

[0080] At the same time, in Example 5, even if a sensor failure is determined by any one of Example 1, Example 2, Example 3, and Example 4, the sensor failure will not be immediately confirmed. Instead, the sensor failure can be confirmed only when the "unexpected data generation conditions" described below are simultaneously met.

[0081] Here, in the unexpected data generation conditions, such as Figure 10 and Figure 11 As shown, the slopes of the upper limit straight lines 810 and 910 connecting the upper limit values ​​of the sensor output data and the lower limit straight lines 820 and 920 connecting the lower limit values ​​of the sensor output data are calculated, and when the slope difference calculated in the above [Mathematical Expression 2] is equal to or greater than the preset value, it can be determined that unexpected data has occurred.

[0082] Therefore, when the sensor is determined to be faulty by any one of the first, second, third, and fourth embodiments, and the slope difference Idiff calculated using [Mathematical Expression 2] that satisfies the unexpected data generation condition is equal to or greater than the preset value, it is set to confirm the sensor failure.

[0083] [Mathematical expression 2]

[0084] I diff =|I max -I min |

[0085] Among them, Imax represents the slope of the upper limit straight line connecting the upper limit of the sensor output data, Imin represents the slope of the lower limit straight line connecting the lower limit of the sensor output data, and I diff Indicates the slope difference (absolute value).

[0086] More specifically, if Figure 10 and Figure 11 As shown, sensor data is collected at a certain time interval, and the slope of the upper limit straight line 810 connecting the upper end of the collected data and the slope of the lower limit straight line 820 connecting the lower end of the collected data are calculated respectively. Then, the slope difference of the two straight lines is calculated. diff , when the difference is not large (less than the preset value), it is considered that the sensor data moves within the error range, and it can be determined that the sensor is operating normally. In addition, when the slope difference between the two straight lines is I diff When it is greater than the preset value, it can be determined that the sensor is malfunctioning because an inaccurate value is output due to a sensor malfunction.

[0087] That is to say, if Figure 10 As shown, the slope of the upper limit line 810 is 0.26, and the slope of the lower limit line 820 is 0.24, so the slope difference between the two lines is I diff The value is 0.02, which is smaller than the preset reference value of 0.12, so it can be determined that the sensor is working properly.

[0088] At the same time, when the upper limit straight line or the lower limit straight line appears as a curved line, the slope of each segment can be compared by dividing the area where the straight line is curved, or the slope can be compared by calculating the average slope over a certain period of time.

[0089] See also Figure 11 , first, we will describe the case where the slope of each segment is compared by dividing the region at each point where the straight line bends. Figure 11 In the example, upper limit line 910 includes three lines. First line 911 has a slope of 0.26, second line 912 has a slope of 0.45, and third line 913 has a slope of 0.38. When lower limit line 920 has a slope of 0.24, the difference between first line 911 and lower limit line 920 (0.26-0.24) is 0.02, which is less than the preset reference value of 0.12. Therefore, the sensor is considered to be operating normally. However, second line 912 has a slope difference of 0.21 from lower limit line 920 (0.45-0.24), which is greater than the preset reference value of 0.12. Therefore, the sensor is considered to be operating abnormally. Third line 913 has a slope difference of 0.14 from lower limit line 920 (0.38-0.24), which is greater than the preset reference value of 0.12. Therefore, the sensor is considered to be operating abnormally. In this way, by dividing the area at each bend of the straight line and comparing the slope of each section, it is possible to determine whether a fault has occurred and estimate the time when the fault occurred, which is very useful when it is necessary to check the time when the fault occurred.

[0090] Next, you can compare the slopes by averaging the slopes over a certain period of time. Figure 11 The average slope of upper limit line 910 throughout the entire segment is ((0.24 + 0.45 + 0.38) / 3) = 0.35. The difference from the average slope of lower limit line 920 (0.24) is 0.11, which is less than the preset reference value of 0.12. Therefore, it can be determined that the sensor is operating normally. In this way, determining faults by calculating the average slope over a certain period of time can reduce the sensitivity of fault determination. Even if a temporary slope change occurs, it will not be determined as a fault as long as the average value does not exceed the reference value. Therefore, unnecessary fault determinations can be avoided.

[0091] According to the above-mentioned invention disclosure, the electric heating brick is provided with a copper tube for inserting a heating cable such as an electric heating wire and a copper film formed on the top of the copper tube. Therefore, providing such an electric heating brick allows the heat generated by the heating cable to be more easily released through the upper surface of the brick.

[0092] Furthermore, by providing at least one magnetic component on one side, an electric heating tile that is easy to install and maintain through magnetic coupling can be provided.

[0093] Furthermore, by including a control module electrically connected to the electric heating brick, an electric heating brick capable of measuring the temperature of the copper pipe and safely controlling the heating state of the electric heating brick can be provided.

[0094] In addition, according to an embodiment disclosed in the present invention, the method for controlling the electric heating brick can be recorded on a readable medium including program instructions for performing various computer-implemented operations. The computer-readable medium can be program instructions, data files, data structures, etc., alone or in combination. The program instructions of the medium can be specially designed and constructed for the present invention, or can be widely known to ordinary technicians in the field of computer software. Examples of computer-readable recording media can include magnetic media such as hard disks, floppy disks and magnetic 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 instructions, such as ROM, RAM and flash memory. Examples of program instructions can include not only machine language code, such as machine language code created by a compiler, but also high-level language code that can be executed by a computer using an interpreter, etc.
