Description

[Technical Field]

[0001] This disclosure relates to an electric heating tile including a heating element, and more particularly to an electric heating tile in the shape of a block in which a temperature sensor and heating element are arranged for a user to monitor the temperature of the tile and control heating by the heating element. [Background technology]

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

[0003] Many of the interior materials used in such buildings are heavy and are used solely for aesthetic purposes, without considering functionality.

[0004] On the other hand, indoor heating in buildings can be divided into two types: forced air heating, which uses electric heaters or burns fuels such as natural gas to warm cold air and blow that warm air into the room; and radiant heating, which heats the floor or walls and warms the room through radiation from the floor or walls.

[0005] In particular, radiant heating is widely used due to its high heating efficiency. This type of radiant heating can be divided into two categories: heating that sends hot water through pipes under the floor or behind the walls to warm the floor or walls, and heating that embeds electric heating wires in the floor or walls to warm them.

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

[0007] However, heating using electric heating wires has its drawbacks, as it requires a series of complex procedures, including laying the heating wires under the floor or behind the walls, pouring cement over them, laying additional tiles for decoration or surface covering, and fixing those tiles onto the hardened and dried cement, resulting in significant labor and construction costs. Furthermore, heating using electric heating wires generates a large amount of electromagnetic radiation that is harmful to human health.

[0008] To solve these problems, floor heating systems using planar or linear heating elements that generate less electromagnetic waves and conduct heat efficiently are being used.

[0009] Specifically, in the case of floor heating installation using surface heating elements, insulation material is laid on the floor to be heated, and then the surface heating elements are applied on top of that.

[0010] However, planar heating elements are weak and easily damaged by external impacts, and are also susceptible to moisture, which can cause short circuits and fires. Furthermore, if some planar heating elements are damaged, repairs become 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 mounted adjacent to the first surface and enclosed within the tile body.

[0012] However, in conventional technology, since a heating wire and a heat-conducting tile 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 circuits in the heating wire, potentially reducing not only functionality but also safety.

[0013] Furthermore, inserting a heating wire into a square block base requires machining a heating wire fitting groove and cavity on 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, research is needed on heated tiles that are easy to install and repair, and can be used safely without causing accidents such as fires. [Overview of the Initiative]

[0015] The present disclosure aims to provide electric heating tiles in the form of ceramic modules with built-in heating wires, which include fastening members on one side so that they can be easily connected to each other and installed in a simple manner.

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

[0026] The specific details, including the problems this disclosure aims to solve, the means for solving those problems, and the effects of this disclosure, as described above, are described in the embodiments and drawings below. The advantages and features of this disclosure, and how to achieve them, will become apparent by referring to the embodiments described in detail below, together with the accompanying drawings.

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

[0028] The present disclosure, which has the title of the present invention, will be described in detail below with reference to the attached Figure 1.

[0029] Figure 1 is a diagram of an electric heating tile according to one embodiment of the present disclosure; Figure 2 is a diagram showing the first layer of the electric heating tile according to one embodiment of the present disclosure; Figure 3 is a diagram showing the second layer of the electric heating tile according to one embodiment of the present disclosure; Figures 4 to 6 are diagrams showing the lower cover of the electric heating tile according to one embodiment of the present disclosure; Figure 7 is a diagram showing the control module of the electric heating tile according to one embodiment of the present disclosure; and Figure 8 is a diagram showing how the first and second layers of the electric heating tile according to one embodiment of the present disclosure are combined.

[0030] [Embodiment 1] Referring to Figures 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 disposed on the upper surface of the first layer 110 and including an electric 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.

[0031] For example, the upper cover 130 may be made from various materials such as ceramic, wood, and synthetic resin, and the lower cover may be made from synthetic resin such as PVC.

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

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

[0034] As shown in Figure 5, the electric heating tiles 100 can be joined to each other by fastening members 141. That is, since the electric heating tiles 100 can be formed in the form of assembled modules, it may be possible to place the electric heating tiles 100 not only over the entire area but also in partial areas where construction is required.

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

[0036] The lower cover 140 may include a cable 142, one end of which is connected to a fastening member 141 and the other end of which is connected to a 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] Therefore, after the heating tiles 100 are connected to each other, it may be possible to pull out a cable 142 from any one of the heating tiles 100 and connect it to the control module 150.

[0039] On the other hand, 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 user control signals 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 signals received from the communication unit 152.

[0040] For example, the user's control signals may include information such as the heating reservation time, maximum heating temperature, and minimum heating temperature.

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

[0042] On the other hand, 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 acquisition unit that collects temperature data from a temperature sensor based on the unique sequence.

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

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

[0046] Therefore, it becomes possible to monitor whether or not an error has occurred in the temperature sensor 111 and heating wire 121 included in each heating tile 100, and it becomes possible to quickly replace the heating tile 100 that has an error.

[0047] On the other hand, as shown in Figure 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 terminal 1121 provided in 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 terminal 1122 provided in the first layer 110.

[0048] In that 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 soldering, and conductive paste may be applied to the soldered portion.

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

[0050] [Embodiment 2] On the other hand, in order to determine whether or not noise is generated 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 foreign matter adheres to the surface of a temperature sensor, the values ​​measured by the sensor will show an irregular pattern. Considering this characteristic, it may be possible to determine not only whether or not foreign matter is attached to the sensor surface, but also whether or not an error is occurring in the sensor's operation.

[0052] For this purpose, a sensor error monitoring unit (not shown) can calculate the mean and standard deviation of multiple values ​​measured by the sensor over a predetermined period. If the number of values ​​that fall outside the standard deviation of the mean of the multiple values ​​(hereinafter referred to as "noise data") is equal to or greater than a predetermined number (e.g., 5), the sensor error monitoring unit (not shown) can estimate that foreign matter is adhering to the surface of the sensor.

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

[0054] Here, the maximum difference value of the time interval between noise data calculated according to the following equation 1 (M d ) is the average value of the time interval between noise data calculated according to the following equation 2 (T avg If the value obtained by multiplying the value by a constant (for example, 2) is equal to or greater than the value obtained by multiplying the value by the constant, then the time interval cannot be determined to be constant.

number

[0055] For example, as shown in Table 1 below, when the data of T0 to T 20 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, the noise data are 14, 18, 6, 2, 17, 3, a total of 6. Since the number of noises is more than 5, which is the preset value, it can be assumed that foreign matter adheres to the sensor surface. [Table 1] To determine whether the noise appears irregularly, the results calculated according to Equation 1 and Equation 2 are as follows. As shown in Table 2 below, the maximum difference (M d ) between the time intervals of noise data is 7, which is obtained by subtracting 1 from 8, and the average value (T avg ) of the time intervals between noise data is 3.5. [Table 2] Therefore, since 7, which is the maximum difference value (M d ) between the time intervals of noise data, is within the range equal to or greater than twice the average value (T avg ) of 3.5 of the time intervals between noise data, it can be confirmed that foreign matter adheres 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 adhering to the sensor surface through a sensor error monitoring unit, and as a result, it may be possible to more accurately determine whether or not the temperature sensor is operating normally.

[0057] The electric heating tiles according to this disclosure are in the form of ceramic modules with embedded heating wires and may include fastening members on one side so that they can be easily coupled to one another and installed in a simple manner.

[0058] Furthermore, the electric heating tile of this 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 to control heating by the heating wire in a safe and simple manner based on the temperature data.

[0059] Furthermore, a method for controlling a heating tile according to one 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, etc., individually or in combination thereof.
