Description

[Technical Field]

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

[0002] Generally, plate-shaped interior materials made of tiles, wood, metal, synthetic resin, etc. are attached to the interior walls of buildings to decorate specific spaces.

[0003] Many of the interior materials used in these buildings have the problem of being heavy, and are used solely as interior materials designed to look good, without any consideration of functionality.

[0004] Meanwhile, indoor heating in buildings can be divided into two types: forced air heating, which uses an electric heater or burns fuel such as natural gas to heat cold air and then blows that air into the room; and radiant heating, which heats the floor or walls and then heats the room by radiation from the floor or walls.

[0005] Radiant heating is particularly popular due to its high heating efficiency. Radiant heating can be divided into two types: heating that uses hot water pipes under the floor or behind the walls to heat the floor or walls, and heating that uses electric heating wires embedded in the floor or walls to heat the floor or walls.

[0006] However, in the case of radiant heating using hot water, there is a possibility of water leakage due to corrosion or bursting of pipes, so heating using hot water is gradually being replaced by heating using electric heating wires.

[0007] However, heating using electric heating wires requires a series of complicated steps, such as laying the heating wires under the floor or behind the walls, pouring cement over them, laying additional tiles for decoration or to cover the surface, and fixing the tiles on top of the hardened and dried cement, which requires a lot of labor and construction costs. Furthermore, heating using electric heating wires generates a large amount of electromagnetic waves that are harmful to the human body.

[0008] To solve these problems, floor heating systems are used that use sheet or linear heating elements that generate less electromagnetic waves and transfer heat easily.

[0009] Specifically, in the case of floor heating construction using a sheet heating element, a heat insulating material is laid on the floor to be heated, and then the sheet heating element is applied on top of that.

[0010] However, the sheet heating elements are weak and easily damaged by external impacts, and are vulnerable to moisture, which can lead to fires due to short circuits. Furthermore, if some of the sheet heating elements are damaged, repairs are difficult.

[0011] Meanwhile, U.S. Patent Application Publication No. 2004 / 0109681 discloses a modular electric heating tile including a tile body and an electric heating unit. The tile body is made of a material selected from the group consisting of clay and cement and has two opposing first and second surfaces. The electric heating unit is attached adjacent to the first surface so as to be enclosed within the tile body.

[0012] However, in the case of conventional technology, because a heating wire and a thermally conductive tile body are used as the heating medium, it is difficult to ensure a sufficient connection area between the two, which can lead to poor heat transfer and the possibility of short-circuiting of the heating wire, reducing not only functionality but also safety.

[0013] Furthermore, in order to insert the heating wire into the square block base, it is necessary to machine a groove and a cavity for fitting the heating wire into the surface of the square block base before attaching the heating wire, which is disadvantageous in terms of manufacturing capacity.

[0014] Therefore, in order to solve the above problems, it is necessary to research heating tiles that are easy to install and repair, and can be used safely without causing accidents such as fires. Summary of the Invention

[0015] The present disclosure aims to provide an electric heating tile in the form of a ceramic module containing an electric heating wire, which includes fastening members on one side so that it can be easily connected to each other and installed in a simple manner.

[0016] Furthermore, the present disclosure aims to provide an electric heating tile that includes a control module connected to the electric heating tile to collect temperature data from a temperature sensor disposed within the electric heating tile and control heating by the heating wire in a safe and simple manner based on the temperature data.

[0017] The problems that the present disclosure aims to solve are not limited to the problems described above, and a person skilled in the art to which the present disclosure pertains will be able to clearly understand other problems that the present disclosure aims to solve, not described in this specification, from the following description.

[0026] The specific contents including the problems to be solved by the present disclosure, means for solving the problems, and effects of the present disclosure as described above are described in the following embodiments and drawings. Advantages and features of the present disclosure, as well as methods for achieving them, will become apparent by referring to the following detailed description of the embodiments together with the accompanying drawings.

[0027] The scope of the present disclosure is not limited to the embodiments described below, and various modifications may be made by those skilled in the art within the scope of the technical gist of the present disclosure.

[0028] The present disclosure entitled "The Invention" will now be described in detail with reference to the accompanying FIG.

[0029] FIG. 1 is a diagram of an electric heating tile according to one embodiment of the present disclosure, FIG. 2 is a diagram showing a first layer of electric heating tiles according to one embodiment of the present disclosure, FIG. 3 is a diagram showing a second layer of electric heating tiles according to one embodiment of the present disclosure, FIGS. 4-6 are diagrams showing a bottom cover of an electric heating tile according to one embodiment of the present disclosure, FIG. 7 is a diagram showing a control module of an electric heating tile according to one embodiment of the present disclosure, and FIG. 8 is a diagram showing how the first and second layers of electric heating tiles according to one embodiment of the present disclosure are combined.

[0030] [Embodiment 1] 1 to 3, an electric heating tile 100 according to one embodiment of the present disclosure may include a first layer 110 having at least one temperature sensor 111 and a power line 112 electrically connected to the temperature sensor 111 formed thereon, a second layer 120 arranged on the upper surface of the first layer 110 and including an electric heating line 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.

[0031] For example, the top cover 130 may be made from a variety of materials such as ceramic, wood, and synthetic resin, and the bottom cover may be made from a synthetic resin such as PVC.

[0032] For example, the thickness of the gap formed between the first layer 110 and the top cover 130 may be less than a preset maximum thickness (eg, 10 mm).

[0033] Meanwhile, referring to FIG. 4, the lower cover 140 may have at least one fastening member 141 on one side thereof that is electrically connected to the power line 112 formed on the first layer 110 .

[0034] 5, the electric heating tiles 100 can be connected to each other by fastening members 141. That is, the electric heating tiles 100 can be formed in the form of modules that can be assembled, so that the electric heating tiles 100 can be placed not only in the entire area but also in a partial area where construction is required.

[0035] Meanwhile, referring to FIGS. 6 and 7, the electric heating tile 100 may further include a control module 150 that controls heating by the electric heating wire.

[0036] The bottom cover 140 may include a cable 142 that is coupled at one end to a fastener 141 and at the other end to the control module 150 .

[0037] For example, a groove into which the cable 142 is inserted may be formed in the area of ​​the lower cover 140 where the fastening member 141 is located.

[0038] Thus, after the electric heating tiles 100 are coupled together, it may be possible to pull the cable 142 out from any one of the electric heating tiles 100 and connect it to the control module 150 .

[0039] Meanwhile, the control module 150 may include a power supply unit 151 that supplies power to the temperature sensor 111 and the power line 112, a communication unit 152 that receives a user control signal from a predetermined user terminal, and a heating wire control unit 153 that controls heating by the heating wire 121 based on the user control signal received from the communication unit 152.

[0040] For example, the user control signal may include information about the heating reservation time, maximum heating temperature, minimum heating temperature, and the like.

[0041] Therefore, the heating wire control unit 153 can control the heating by the heating wire 121 by adjusting the level, duty ratio, etc. of the voltage applied to the heating wire 121 based on the user's control signal.

[0042] Meanwhile, the first layer 110 may further include a communication tag (not shown), and the control module 150 may further include a tag recognition unit (not shown) that recognizes the communication tag.

[0043] More specifically, the tag recognition unit may include a code assignment unit that assigns a unique sequence to the communication tags when at least two communication tags are recognized, and a temperature collection unit that collects temperature data from the temperature sensor based on the unique sequence.

[0044] Therefore, when multiple electric heating tiles 100 are combined, each of the multiple electric heating tiles 100 can be recognized by a tag recognition unit, and a unique order can be assigned to the communication tags included in the electric heating tiles 100, thereby making it possible to monitor the temperature of each of the multiple electric heating tiles 100.

[0045] For example, if four electric heating tiles 100 are installed, the control module 150 may recognize each electric heating tile 100 through a communication tag included in the electric heating tile 100. In this case, it may be possible to monitor the heating by each electric heating tile 100.

[0046] Therefore, it may be possible to monitor whether an error has occurred in the temperature sensor 111 and heating wire 121 included in each heating tile 100, and it may be possible to quickly replace a heating tile 100 that has an error.

[0047] On the other hand, as shown in FIG. 8, the second layer 120 may include a first terminal 1211 provided at one end of the heating wire 121 at a position corresponding to the position of the positive electrode terminal 1121 provided on the first layer 110, and a second terminal 1212 provided at the other end of the heating wire 121 at a position corresponding to the position of the negative electrode terminal 1122 provided on the first layer 110.

[0048] 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 can be connected to the positive terminal 1121 and the negative terminal 1122, respectively, by soldering, and a conductive paste can be applied to the soldered portions.

[0049] As another example, a thermally conductive sheet may be attached to the side of the upper cover 130, so that when multiple electric heating tiles 100 are combined with each other, heat can be rapidly conducted between the electric heating tiles 100.

[0050] [Embodiment 2] Meanwhile, in order to determine whether noise is occurring due to foreign matter adhering to the temperature sensor 111, the control module 150 may further include a sensor error monitoring unit (not shown) that receives and analyzes data collected from the temperature sensor.

[0051] In other words, if a foreign object adheres to the surface of the temperature sensor, the values ​​measured by the sensor will show an irregular pattern. In this regard, taking such characteristics into consideration, it may be possible to not only determine whether a foreign object is attached to the sensor surface, but also to determine whether an error has occurred in the operation of the sensor.

[0052] For this purpose, the sensor error monitoring unit (not shown) may calculate the average value and standard deviation of a plurality of values ​​measured by the sensor over a predetermined period of time, and if the number of values ​​(hereinafter referred to as "noise data") that deviate from the average value by a certain number of standard deviations is equal to or greater than a predetermined number (e.g., 5), the sensor error monitoring unit (not shown) may infer that a foreign substance is attached to the surface of the sensor.

[0053] At the same time, a sensor error monitoring unit (not shown) can calculate the interval between the times when each noise data was measured, and if the interval is not constant, can determine that a foreign object is attached to the sensor surface.

[0054] Here, the maximum difference value (M d ) is the average value of the time interval between noise data (T avg ) multiplied by a constant (e.g., 2), the time interval cannot be determined to be constant.

number

number

[0055] For example, as shown in Table 1 below, T0 to T 20 If the data are 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 six noise data: 14, 18, 6, 2, 17, and 3. Since the number of noise data is greater than the preset value of 5, it can be assumed that there is foreign matter attached to the sensor surface. [Table 1] [Table 1] To determine whether noise appears irregularly, the calculation results according to Equations 1 and 2 are as follows: As shown in Table 2 below, the maximum difference in time intervals between noise data (M d ) is 8 minus 1, which is 7, and the average time interval between noise data (T avg ) is 3.5. [Table 2] [Table 2] Therefore, the maximum difference value of the time interval between noise data (M d ) is the average time interval between noise data (T avg ), it can be confirmed that foreign matter is attached to the sensor surface.

[0056] According to one embodiment of the present disclosure as described above, it may be possible to monitor and detect errors caused by foreign matter attached to the sensor surface through the sensor error monitoring unit, and as a result, it may be possible to more accurately determine whether the temperature sensor is operating normally.

[0057] The electric heating tiles according to the present disclosure are in the form of ceramic modules containing electric heating wires, and may include fastening members on one side so that they can be easily joined together and installed in a simple manner.

[0058] Furthermore, the electric heating tile of the present disclosure may include a control module connected to the electric heating tile to collect temperature data from a temperature sensor provided within the electric heating tile and control heating by the heating wire in a safe and simple manner based on the temperature data.

[0059] Furthermore, a method for controlling an electric heating tile according to an embodiment of the present disclosure may be recorded on a computer-readable medium containing program commands for performing various computer-executable operations. The computer-readable medium may include program commands, data files, data structures, and the like, individually or in combination. The program commands on the medium may be specially designed and constructed for the present disclosure or may be available through common knowledge to those skilled in the art of computer software. Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks, and magnetic tape; optical media such as CD-ROMs and DVDs; magneto-optical media such as floptical disks; 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 code, such as that produced by a compiler, but also high-level language code that can be executed by a computer using an interpreter, for example.

[0060] Although an embodiment of the present disclosure has been described with reference to limited examples and drawings, the present disclosure is not limited to the examples described above. Those skilled in the art to which the present disclosure pertains will be able to make various modifications and variations to the examples described herein.
