Description

System for a divisional heating

The present invention relates to a split heating system having a temperature sensor on a heating film, and more particularly, to install a separate temperature sensor inside a plurality of divided heating films, and to divide each divided sensor using the mounted temperature sensor. A split heating system for selectively supplying current to a heating film.

In general, the electric floor heating system is already installed on the bottom of the ondol panel heating heater to increase the temperature of the floor, or hot water pipe for circulating hot water on the floor to increase the temperature is already widely used Known.

However, since this method increases the volume of panels and pipes when used in a large place to build a heating system, there is a difficulty in moving and installation, and may also cause a problem of cost due to increased manpower.

Therefore, the structure which installs an insulation film sheet which mainly contains carbon etc. to a constant size, supplies this electric current after installing this film sheet on the floor, and the structure which equips the floor heating system is shown well in FIG.

1 is a schematic diagram showing a configuration of a heating system using an insulating film in the related art.

As shown in FIG. 1, a heating system using a conventional heating film includes a power source 11 for supplying current through current supply terminals 40 provided on both sides of a plurality of divided heating films 51 to 53. The temperature controller 10 adjusts the temperature of the heat generating films 51 to 53 according to the user's operation, and the temperature sensor 20 mounted on one of the plurality of heat generating films 51 to 53.

More specifically, a conventional heating system using a film, first, the heating film of a certain width is cut to the width of the room, and then two or three sheets are connected to the heating film in parallel. 1 illustrates a plurality of heat generating films connected in parallel with three sheets. By supplying a current to the current supply terminal 40 within the temperature range set by the temperature controller 10 to the plurality of heat generating films 51 to 53 connected in parallel, these heat generating films 51 to 53 are predetermined. By heating up to the temperature of the floor was able to maintain a constant temperature warm.

In addition, in this heating system, when the temperature sensor 20 is mounted inside the one heat generating film 51 and the temperature of the heat generating film 51 rises above the temperature set by the temperature controller 10, the temperature no longer rises. The electricity is cut off so as to protect the plurality of heating films 51 to 53.

Here, the temperature controller 10 controls the supply of current from the power source 11 according to the sensing temperature of the temperature sensor 20 mounted inside one heating film 51 by using a contact driving method using a relay. do.

However, as shown in FIG. 1, when the temperature sensor 20 is provided only on one heating film 51, when the furniture or an object having a heat insulating effect is placed thereon, the temperature of the sensor portion rises easily. Since the temperature sensor 20 continues to be turned on / off in the temperature range set by the controller 10, in the heating films 52 and 53 where the temperature sensor 20 is not installed, the temperature sensor 20 is kept below the set temperature, and the temperature controller ( 10) Unnecessary electrical loss can be caused by repeated operation of relay installed inside.

On the contrary, the outside air is placed on the heating film 52 or 53 without the temperature sensor 20 placed thereon, or an object having a heat insulating effect thereon or the heating film 51 with the temperature sensor 20 installed therein blown from the surroundings. If the temperature does not rise due to the temperature of the heat-generating film 52, 53 without the temperature sensor 20 continuously rises and overheats, the film itself may be deformed or the copper foil portion of the film may be exposed, even There is also a problem that may occur due to overheating of the heat generating film.

In particular, when going out, it is necessary to control the temperature of the plurality of heat-generating films 51 to 53 with one temperature controller 20. When the temperature sensor breaks down, a great accident risk may occur due to overheating of the heat-generating film.

On the other hand, various control means other than the temperature sensor 20 have been devised to overcome such a problem, but all of them have the disadvantage of turning on / off the entire heating film at once, thus reducing the efficiency of current supply. In addition, the room temperature could not be kept constant.

As described above, the conventionally constructed heating system is equipped with a temperature sensor only on one heating film, so that the temperature control of each heating film is impossible, so that the temperature of the indoor floor cannot be maintained uniformly, and the temperature sensor is not installed. Overheating of the heat generating film may cause various fire accidents, so it may be difficult to secure stability.

Therefore, to solve the problems according to the prior art, the present invention is equipped with a temperature sensor on a plurality of divided heating film individually, and compares the detected temperature of the individual temperature sensor and the set temperature of the temperature controller According to the comparison result, at least one of the plurality of heating film to provide a divided heating system independently provided with a controller for controlling to distribute and supply the current conveniently.

In addition, each heating film is provided with a plurality of individual temperature sensors, and provides a divided heating system that controls to supply the current more accurately by sensing the average temperature from these individual temperature sensors.

In order to achieve the above object, in the divided heating system using a plurality of heat generating members according to the present invention, current is supplied through current supply terminals 220 provided on both sides of the plurality of heat generating members 201 to 206. A power supply unit 210; A temperature controller 230 for setting the plurality of heat generating members to a desired temperature according to a user's operation; Individual temperature sensors 301 to 306 mounted to each of the plurality of heat generating members 201 to 206 to sense temperature changes of the plurality of heat generating members 201 to 206 due to the supply of the current from the power supply 210. )Wow; The temperature set by the temperature controller 230 and the individual temperature detected by the individual temperature sensors 301 to 306 are compared one by one, so that the current is supplied or cut off to the plurality of heat generating members according to the comparison result. It includes a controller 100.

In addition, the controller 100 converts each of the analog signals input from the memory 130 for storing the set temperature input through the temperature controller 230 and the individual temperature sensors 301 to 306 into digital signals. A / D converter 120 and the respective individual temperature output from the A / D converter 120 and the set temperature stored in the memory 130 are compared one by one, and the plurality of based on the comparison result A control unit 140 for outputting a switching driving signal for controlling a current to be supplied or cut off to at least one of the heating members of the heating member, and a current supply terminal based on the switching driving signal received from the control unit 140 ( And a switching circuit 150 provided with a plurality of switches for determining whether current is supplied to 220.

The present invention compares the individual temperature of the individual temperature sensor mounted on the plurality of divided heating film and the set temperature of the temperature controller to control the current supplied on each divided heating film by using one controller. It is possible to prevent fire due to overheating of the heat generating film, and it is relatively convenient to control and the cost of building equipment can be reduced.

In addition, since the controller is provided independently, it can function as a protection circuit to protect all devices in case of an accident or emergency, and in particular, when going out, it is connected to current supply terminals provided on both sides of the plurality of heat generating films. It is possible to supply current sequentially from the power supply via the switching circuit.

In addition, by connecting and mounting a plurality of individual temperature sensors in series for each heating film, measuring the temperature values coming from the plurality of individual temperature sensors as an average value and supplying a current more accurately using a controller according to this average temperature. It is possible.

Specific details and features of the present invention will be further embodied by Examples 1 and 2 of the present invention described below. Hereinafter, exemplary embodiments 1 and 2 will be described with reference to the accompanying drawings.

Example  One

Figure 2 is a schematic diagram showing the overall configuration of a split heating system according to a first embodiment of the present invention.

As shown in FIG. 2, the divided heating system according to the present invention supplies a plurality of heating films 201 to 206 and current input terminals 220 provided on both sides of the heating films 201 to 206. A power supply 210 for supplying current through the line 240, a temperature controller 230 for setting the plurality of heat generating films 201 to 206 to a desired temperature range according to a user's operation, and the heat generating film 201. Each of the individual temperature sensors 301 to 306 attached to the respective ones, and the controller 100 which determines and controls which of the plurality of heat generating films 201 to 206 to supply current.

More specifically, the heat generating film 201 is an insulating film that generates heat when a band-shaped carbon is attached and an electric current flows, and the other heat generating films 202 to 206 are also divided in the same configuration. Here, the band shape shown in the heat generating films 202 to 206 is omitted in order to clearly show the connection lines of the individual temperature sensors 301 to 306.

In addition, the plurality of heat generating films 201 to 206 are respectively equipped with individual temperature sensors 301 to 306 to detect heat generated from each of the heat generating films 201 to 206, and the detected temperature is an individual temperature. It is defined as

The temperature controller 230 sets a temperature such that the plurality of heat generating films 201 to 206 are maintained at a desired temperature, and the set temperature is defined as a set temperature. The set temperature here indicates not only one accurate temperature but also preferably represented by a range of temperatures.

The controller 100 is connected to the power supply 210 and compares the set temperature set by the temperature controller 230 and each individual temperature detected by the individual temperature sensors 301 to 306 with each other and according to the comparison result. The supply of current from the power supply 210 is controlled by determining which heating film to supply or cut off the current output from 210.

For example, when the current is supplied through the current supply terminal 220 formed on both sides of the plurality of heating films 201 to 206 from the power supply via the supply line 240, the temperature controller 230 at a temperature desired by the user. In the initial setting, since the plurality of heat generating films 201 to 206 are lower than the set temperature, each of the divided heat generating films 201 to 206 receives current and continues to generate heat until the set temperature is higher than the set temperature. Thereafter, the plurality of heating films 201 to 206 are constantly maintained at the set temperature in close proximity to the temperature set by the temperature controller 230.

However, if an object having a furniture or an insulation effect is placed on a portion of the individual temperature sensor mounted on the heating film 206, a temperature rise due to pressure and insulation occurs at that portion, and the setting set by the temperature controller 230 occurs. The temperature of the heat generating film 206 rises above the temperature, and the individual temperature sensor 301 sends the controller 100 as this elevated temperature, that is, the individual temperature.

Next, since the controller 100 receiving the individual temperature detected by the individual temperature sensor 301 is higher than the set temperature set by the temperature controller 230, the controller 100 cuts off the current supplied to the heating film 206 to generate heat. Overheating of the film can be prevented, and in particular, only one heating film cuts off the current because the current is cut off, and the remaining heating film 201 to 205 are constantly maintained at a temperature close to the set temperature, thereby performing indoor floor heating. Can have high power efficiency.

As described above, the control operation between the individual temperature sensor 301 and the controller 100 due to the temperature rise of the heat generating film 206 is described, but the other heat generating films 201 to 205 also have the controller 100. The same can be controlled by In addition, since the operation is not limited to one heating film but the supply line 240 is connected to the controller 100 individually, even when the temperature of two or more heating films rises, current is supplied to each heating film. It is possible to cut off.

That is, the detected individual temperatures from the individual temperature sensors 301 to 306 respectively mounted on the plurality of heating films 201 to 206 using one controller 100 are compared with the set temperatures of the temperature controller 230, respectively. By controlling the current supplied to each of the heating films 201 to 206, the temperature of the bottom may be kept evenly warm through increasing or decreasing the temperature of the heating film.

Hereinafter, with reference to FIG. 3, it will be described in what electrical configuration the divided heating system of the present invention is controlled.

3 is a block diagram schematically showing an electrical circuit of a split heating system according to a first embodiment of the present invention.

As shown in FIG. 3, the present invention according to the first embodiment outputs the set temperature set by the temperature controller 230 to the controller 100, and inputs the analog input from each of the individual temperature sensors 301 to 306. By outputting the individual temperature as a signal to the controller 100 and comparing the set temperature and each individual temperature one by one, according to the comparison result, the controller 100 includes a plurality of switches provided in the switching circuit 150 connected to the power supply 210. The switch (not shown) is supplied via the supply line 240 to the current supply terminal 220 of both sides provided for each of the plurality of heating film (201 ~ 206).

As a result, since the current supplied to the heat generating films 201 to 206 is individually controlled on / off according to the temperature change of each heat generating film 201 to 206, it is generated on each divided heat generating film 201 to 206. This can prevent fire due to overheating due to possible temperature rise and floor temperature unevenness due to film temperature drop.

More specifically, when describing the control operation using the internal configuration of the controller 100, the controller 100 converts each analog signal input from the individual temperature sensors (301 ~ 306) into digital signals and outputs A / D Memory 130 for storing the set temperature input through the converter 120, the temperature controller 230, and the individual temperature and the memory 130, which is the respective digital signals output from the A / D converter 120 A control unit for comparing the set temperature stored in the control unit one by one, and outputs a switching drive signal (S1) for controlling to supply or cut off the current to at least one of the plurality of heating film (201 ~ 206) based on the comparison result 140 and a switching circuit including a plurality of switches (not shown) for determining which current supply terminal 220 is supplied based on the switching driving signal S1 received from the controller 140. 150 Include.

Here, since the controller 100 is provided independently of an external circuit, the controller 100 may perform a function as a protection circuit in the overall system, and the switching circuit 150 may include a plurality of transistors, a plurality of triacs, and the like. It is preferable to consist of an active element.

That is, the controller 140 included in the controller 100 used in the split heating system according to the present invention includes a temperature and an individual temperature sensor 301 set within the range of the first set temperature and the second set temperature by the temperature controller 230. And compares the detected individual temperatures one by one, and if the comparison results that at least one of the individual temperatures is less than the first set temperature, the power supply 210 is connected to the heating film equipped with the individual temperature sensors corresponding to the individual temperatures. By outputting the switching driving signal S1 to supply current, the plurality of switches provided in the switching circuit 150 are turned on based on the output switching driving signal S1 to supply the supply line 240. After passing through the current supply terminal 220 attached to both sides of the heating film.

On the other hand, when a result of comparing the first and second set temperatures of the temperature controller 230 and the individual temperatures of the individual temperature sensors 301 to 306 is at least one of the individual temperatures is greater than the second set temperature, the individual corresponding to the individual temperatures By outputting the switching drive signal S1 to cut off the current from the power source 210 to the heat film equipped with a temperature sensor, a plurality of switches provided in the switching circuit 150 based on the output switching drive signal S1. It can be turned off to secure stability due to preventing overheating.

For example, when a plurality of heat generating films maintain a constant temperature at a temperature, when the heat of the heat generating film 203 rises due to external factors and device malfunctions, this increased temperature is inside the heat generating film 203. Detected by the individual temperature sensor 303 mounted on the input via the A / D converter 120 as an individual temperature to the controller, it is determined that the input individual temperature is higher than the second set temperature input from the temperature controller 230 In this case, the controller 140 outputs the switching driving signal S1 to the switching circuit 150 to cut off the current supplied from the power source.

Therefore, by using one controller 100, it is possible to prevent overheating of the heat generating film that may be generated due to external factors and device malfunction for each heat generating film 201 to 206.

On the contrary, if the individual temperature is smaller than the first set temperature, it is possible to continuously supply current to maintain a constant temperature.

In addition, when going out, each of the heat generating films based on the switching driving signal S1 of the controller 140 using the switching circuit 150 connected to the current supply terminals provided on both sides of the plurality of heat generating films 201 to 206. It is also possible to sequentially supply current to 201 to 206.

In this way, the unit included in one controller is used to determine whether the current is supplied or cut off according to the temperature change of each heating film, so that the floor is kept warm evenly when heating the floor, and the power is relatively simple. Can be managed efficiently.

As shown in FIG. 4, the present invention according to the second embodiment is equipped with a plurality of individual temperature sensors 501 to 506 connected in series in a plurality of heat generating films 201 to 206, and the plurality of individual temperature sensors. Using the average value calculation unit (not shown) included in the controller to the temperature input from (501 ~ 506) outputs the average temperature which is the average value for each of the plurality of individual temperature sensors (501 ~ 506) to the controller 140, By comparing this average temperature with the temperature set by the temperature controller 230, it is possible to supply and cut off a current more accurately to each of the heat generating films 201 to 206 divided from each other according to the comparison result.

That is, as described with reference to FIG. 3, the controller 140 compares the set temperature of the temperature controller 230 with the average temperature detected by the plurality of individual temperature sensors 501 to 506, and as a result of the comparison, among the average temperatures. If at least one is less than the set temperature to supply a current from the power supply 210 to the heating film is equipped with a plurality of individual temperature sensors corresponding to the average temperature. This supply operation is the same as that in the first embodiment, and thus is omitted.

In addition, the set temperature of the temperature controller 230 is compared with the average temperature detected by the plurality of individual temperature sensors 501 to 506, and when the comparison results, if at least one of the average temperatures is greater than the set temperature, the plurality of temperatures corresponding to the average temperature. By blocking the current from the power supply 210 to the heating film equipped with an individual temperature sensor. This supply operation is also the same as that of the first embodiment, and thus is omitted.

As such, although not shown in FIG. 4, the temperature sensed by the plurality of individual temperature sensors 501 to 506 mounted in series in the center of each heat generating film is converted into one average value, and the converted average temperature and temperature. By comparing the set temperature of the controller 230, and individually controlling the current supplied to each of the heating film (501 ~ 506) according to the comparison result, to obtain a more accurate temperature value throughout the heating film to obtain each heating film Prevents accidents due to overheating
