[0025]
At the end of the floor heating mat 10, there is a header portion 16 having an inlet for sending warm water into the internal pipe 12 and an outlet for discharging hot water that has made a round of the pipe 12. The floor heating mat 10 and a floor heating apparatus (not shown) that supplies hot water to the mat 10 are connected via the unit 16.
[0026]
FIG. 1 schematically shows a state in which a floor heating mat construction abnormality inspection device 30 according to an embodiment of the present invention is connected to a floor heating mat 10. In FIG. 1, the longitudinal cross section in the direction parallel to the piping 12 of the mat 10 for floor heating is shown. When the floor heating mat 10 is attached to the floor surface, first, the floor heating mat 10 is spread and laid on the base plywood 21, and a floor material 22 such as a flooring material is laid on the floor heating mat 10. Fixing is performed by driving a fixing member such as a nail 24 into the joint portion until it reaches the base plywood 21.
[0027]
The floor heating mat 10 has a structure in which a pipe 12 is stretched around a base sheet 16 made of foamed polyethylene and the like, and a conductive sheet 18 made of aluminum foil is laminated on the entire surface of the floor heating mat 10. Yes. The floor heating mat 10 has a thickness of about 12 mm, and the pipe 12 has an outer diameter of 7.2 mm and an inner diameter of 5 mm.

It is an inspection apparatus that detects whether or not the nail 24 is driven in the vicinity of the pipe 12 so as to cause damage such as a scratch. The inspection signal line 32 extending from the floor heating mat construction abnormality inspection device 30 is composed of the conductive sheet 18 laminated on the surface of the floor heating mat 10 and the metal of the header portion 16 in contact with the hot water in the pipe 12. Connected with the part.
[0029]
FIG. 3 shows a circuit configuration of the floor heating mat construction abnormality inspection device 30 shown in FIG. The floor heating mat construction abnormality inspection device 30 includes an inspection processing control unit 41 that controls and controls the inspection operation. The inspection processing control unit 41 starts and stops inspections and performs various setting operations. An operation unit 42 provided with switches for performing the operation and a display unit 43 for displaying the inspection result and the like are connected. Here, a liquid crystal display is used as the display unit 43.
[0030]
In addition, the floor heating mat construction abnormality inspection device 30 includes a capacitance detection unit 44 that detects a capacitance between the conductive sheet 18 and the hot water in the pipe 12, and conductivity in a state before the nail 24 is driven. A reference capacity storage unit 45 is provided for storing a capacitance (reference capacity) between the sheet 18 and the hot water in the pipe 12. The comparison determination unit 46 compares the reference capacitance stored in the reference capacitance storage unit 45 with the capacitance detected by the capacitance detection unit 44, and whether the nail 24 penetrates the pipe 12 from the difference, Or it is a circuit part which determines the presence or absence of construction abnormality, such as being driven into the very vicinity of the piping 12. FIG.
[0031]
From the inspection processing overall control unit 41, an inspection auxiliary operation instruction signal 47 for instructing an auxiliary operation of inspection to the floor heating device which is a hot water supply source, and from the comparison determination unit 46, an inspection result signal 48 indicating the inspection result. Are output respectively. Further, an inspection signal line 32 for measuring capacitance is provided from the capacitance detection unit 44. Note that the inspection processing overall control unit 41, the reference capacity storage unit 45, the comparison determination unit 46, etc. have a CPU (Central Processing Unit), ROM (Read Only Memory), and RAM (Random Access Memory) as main parts. It consists of a circuit.
[0032]
The capacitance measurement by the capacitance detection unit 44 is performed by various known measurement methods. For example, measurement is performed by a resonance method using resonance between an inductance coil and a calibrated variable capacitor, a susceptance change method, a bridge method, or the like. In the present embodiment, a bridge method suitable for measuring capacitance with high accuracy is used.
[0033]
FIG. 4 is a circuit diagram showing the measurement principle in the bridge method used in the capacitance detection unit 44. In FIG. 4, the capacitor 51 corresponds to the electrostatic capacity between the conductive sheet 18 and the hot water in the pipe 12, and between the conductive sheet 18 and the hot water in the pipe 12 due to the equilibrium condition of the Wheatstone bridge. The capacitance Cx and the resistance component Gx can be obtained from the following equations, respectively.
[0034]
Cx = Cs (R1 / R2) (1)
Gx = Gs (R1 / R2) (2)
This conditional expression is obtained when the bridge is balanced. By supplying a specific frequency by the transmitter 52 and substituting the value of Cs when the voltmeter 53 becomes zero volts into the equation (1) and the like, static electricity between the conductive sheet 18 and the hot water in the pipe 12 is obtained. The electric capacity (Cx) is measured.
[0035]
Next, the operation will be described.
After the floor heating mat 10 is laid on the base plywood 21, hot water is passed through the pipe 12, and the electrostatic capacity (reference capacity) between the conductive sheet 18 and the hot water in the pipe 12 in a state before driving the nail. ). The reference capacity is stored in the reference capacity storage unit 45. A reference capacity value measured in advance when the floor heating mat 10 is shipped from the factory is attached to the floor heating mat 10, and the floor heating mat construction abnormality inspection is performed through the operation unit 42. You may make it register to the reference | standard capacity storage part 45 of the apparatus 30. FIG.
[0036]
Further, a bar code representing the reference capacity measured at the time of shipment from the factory is attached to the floor heating mat 10, and the reference capacity value is stored in the reference capacity storage unit 45 of the floor heating mat construction abnormality inspection apparatus 30 using a bar code reader. You may make it register to.
[0037]
After the reference capacity is registered in the reference capacity storage unit 45 in this way, the work of fixing the flooring 22 on the floor heating mat 10 with the nail 24 is performed. Then, after completion of the construction, the capacitance between the conductive sheet 18 and the hot water in the pipe 12 is measured again using the floor heating mat construction abnormality inspection device 30.
[0038]
Based on the magnitude of the difference between the reference capacity stored in the reference capacity storage section 45 and the capacitance measured after the construction, the comparison / determination section 46 determines whether the nail 24 penetrates the pipe 12 or scratches, etc. It is determined whether the nail 24 is driven in the vicinity of the pipe 12 so as to cause damage, and an inspection signal corresponding to the inspection result is output from the inspection signal line 32 and the inspection result is displayed on the display unit 43.
[0039]
FIG. 5 shows various states in which the nail 24 is driven. The base plywood 21 is fixed on the joists 25 and a heat insulating material is disposed below the base plywood 21. When the nail 24a as a fixing member having conductivity is driven into the place where the small joists 14 are present, a sufficient distance between the nail 24a and the hot water in the pipe 12 is secured. As a result, the capacitance between the conductive sheet 18 and the hot water in the pipe 12 hardly changes.
[0040]
On the other hand, since the conductive nail 24b struck so as to penetrate the pipe 12 is in direct contact with the hot water in the pipe 12, the conductive sheet 18 and the hot water in the pipe 12 are in a conductive state. The capacitance between them changes relatively greatly. Further, if the nail 24c is struck near the pipe 12 so as not to penetrate the pipe 12, but the hot water in the pipe 12 and the nail 24c are very close to each other, the distance between the electrodes is reduced, and the conductive sheet 18 is reduced. And the hot water in the pipe 12 increase to some extent.
[0041]
Therefore, by measuring the capacitance between the conductive sheet 18 and the hot water in the pipe 12, the nail 24 penetrates the pipe 12 as well as when the nail 24 penetrates the pipe 12. It is possible to detect whether or not it has been driven close enough to damage.
[0042]
Next, the floor heating apparatus main body 100 used in combination with the floor heating mat construction abnormality inspection apparatus 30 will be described.
FIG. 6 schematically shows a state in which the floor heating mat 10, the floor heating mat construction abnormality inspection device 30, and the floor heating device main body 100 are connected to each other. The floor heating apparatus main body 100 and the floor heating mat 10 are connected by a connection pipe 101 for supplying hot water and collecting the hot water that has made a round in the floor heating mat 10. The inspection signal line 32 extended from the floor heating mat construction abnormality inspection device 30 is connected to the conductive sheet 18 and the header portion 16 of the floor heating mat 10 and inspected from the floor heating mat construction abnormality inspection device 30. The auxiliary operation instruction signal 47 and the inspection result signal 48 are input to the floor heating apparatus main body 100.
[0043]
The floor heating apparatus main body 100 is based on the inspection assistance operation instruction signal 47 from the floor heating mat construction abnormality inspection apparatus 30 and controls the various operations for assisting the inspection performed by the floor heating mat construction abnormality inspection apparatus 30. Part 110. The inspection auxiliary unit 110 controls the auxiliary operation of the inspection and assists the inspection until the inspection result signal 48 indicating that there is no construction abnormality is input from the floor heating mat construction abnormality inspection device 30. In addition, a normal heating operation for supplying hot water to the floor heating mat 10 is prohibited.
[0044]
FIG. 7 shows a schematic configuration of the floor heating apparatus body 100 shown in FIG. The floor heating apparatus main body 100 performs the prohibition of the inspection auxiliary operation and the heating operation, and the cancellation of the prohibition, with the inspection terminal 111 connected to the signal lines for transmitting the inspection auxiliary operation instruction signal 47 and the inspection result signal 48. An inspection processing control unit 112 and a non-volatile memory 113 for storing whether or not the inspection result signal 48 indicating the inspection pass has already been received from the floor heating mat construction abnormality inspection device 30 are provided. The floor heating apparatus main body 100 includes a combustion control unit 114 that controls a combustion unit (not shown) that heats water for floor heating, and a circulation control unit 115 that includes a pump that sends the heated water to the floor heating mat 10. It has.
[0045]
FIG. 8 shows the flow of the auxiliary inspection operation performed by the floor heating apparatus body 100. When the floor heating mat construction abnormality inspection device 30 starts the inspection operation, it first outputs an inspection auxiliary operation instruction signal 47 for instructing the floor heating device main body 100 to start the supply of hot water. When the floor heating apparatus main body 100 receives a hot water supply start instruction from the floor heating mat construction abnormality inspection apparatus 30 (step S301; Y), the circulation control unit 115 is driven to supply hot water to the floor heating mat 10. Is started (step S302).
[0046]
When the supply of hot water to all the pipes 12 of the floor heating mat 10 is completed, the floor heating apparatus main body 100 sends a water passage completion signal to the floor heating mat construction abnormality inspection apparatus 30. Completion of the supply of hot water can be determined by whether or not a predetermined time has elapsed after the start of supply, or by a temperature change at a location where the hot water returns.
[0047]
The floor heating mat construction abnormality inspection device 30 that has received the water passage completion signal measures the capacitance between the conductive sheet 18 and the hot water in the pipe 12, and after the measurement is finished, warm water is supplied to the floor heating device main body 100. The inspection auxiliary operation instruction signal 47 for instructing the supply stop is sent out.
[0048]
When the floor heating apparatus main body 100 receives the hot water supply stop instruction (step S305; Y), the hot water supply to the floor heating mat 10 is stopped (step S306). The floor heating mat construction abnormality inspection device 30 outputs an inspection result signal 48 indicating the inspection result to the floor heating device main body 100 when the inspection is completed. When the inspection result signal 48 arrives (step S307; Y), the floor heating apparatus body 100 determines whether or not the input inspection result signal 48 is a genuine signal (step S308).
[0049]
The inspection result signal 48 is a digital signal with an error detection code encoded in a predetermined format, and the floor heating apparatus main body 100 determines whether or not the code information has arrived and an error added to the code. It is checked whether or not a transmission error has occurred based on the detected code.
[0050]
By using such code information as the inspection result signal 48, it is possible to prevent an operator from falsifying the inspection result by inputting a pseudo signal or misidentifying the inspection result due to noise or the like.
[0051]
When it is the genuine inspection result signal 48 (step S308; Y) and the content thereof indicates that the inspection has passed (step S309; Y), the inspection processing control unit 112 stores information indicating that the inspection has passed, in the nonvolatile memory 113. (Step S310). When the inspection result signal 48 indicates that the inspection has failed, the registration of the inspection pass is deleted (step S311). As a result, even if the inspection passed is registered once in the nonvolatile memory 113, the registration that has passed the inspection is canceled when the final inspection fails.
[0052]
When the floor heating apparatus main body 100 includes a plurality of circuits for supplying hot water to the floor heating mat 10, the pass / fail of the inspection is registered in the nonvolatile memory 113 for each path. In this case, the floor heating mat construction abnormality inspection device 30 adds the hot water supply start instruction and the identification number of the path to be inspected to the inspection result signal 48. The floor heating apparatus main body 100 supplies hot water to the path corresponding to the identification number added to the received signal. Moreover, when the floor heating apparatus main body 100 receives the inspection result signal 48 indicating acceptance, the floor heating apparatus main body 100 identifies which route has passed by the identification number, and registers the inspection passed for the corresponding route.
[0053]
FIG. 9 shows an operation flow of the floor heating apparatus main body 100 when starting a normal heating operation. When an instruction to start floor heating is received from the remote control unit or the like (step S401; Y), the floor heating apparatus body 100 checks whether or not “passed inspection” is registered in the nonvolatile memory 113 (step S402). When the passed inspection is registered for all the paths for supplying hot water (step S402; Y), the floor heating apparatus main body 100 starts the floor heating operation by causing the combustion control unit 114 and the circulation control unit 115 to function. (Step S403). On the other hand, if any one of the paths through which the hot water is to be supplied is not registered in the nonvolatile memory 113 (step S402; N), a warning indicating that the inspection has not been registered is issued. While displaying on the remote control operation unit, a predetermined warning sound is sounded (step S404).
[0054]
In this way, when the inspection passed is not registered, normal floor heating operation is prohibited, so the inspection of whether or not the piping has been damaged at the time of construction is omitted, or the inspection result is false Construction can be prevented.
[0055]
Next, various modes when connecting the floor heating mat construction abnormality inspection device 30 to the floor heating device main body 100 are shown. 6, the floor heating mat construction abnormality inspection device 30 is independently provided outside the floor heating device main body 100, and the signal line from the floor heating mat construction abnormality inspection device 30 is connected to the inspection auxiliary unit 110. It is supposed to be. On the other hand, in FIG. 10, the floor heating mat construction abnormality inspection device 30 is provided inside the floor heating device main body 100 and integrated. In FIG. 11, the floor heating mat construction abnormality inspection device 30 is incorporated in the remote control operation unit 120 of the floor heating device main body 100.
[0056]
In FIG. 12, the floor heating mat construction abnormality inspection device 30 is provided independently, and the floor heating apparatus main body 100 and the floor heating mat construction abnormality inspection device 30 are connected via the remote control operation unit 120. The inspection auxiliary part 110 is arranged inside the interior. In FIG. 13, the floor heating mat construction abnormality inspection device 30 is connected via the remote control operation unit 120, and the inspection auxiliary unit 110 is provided in the floor heating device main body 100.
[0057]
Since the remote control operation unit 120 is usually installed on the wall of a room where the floor heating mat 10 is laid, the floor heating mat construction abnormality inspection device 30 is connected to the remote control operation unit 120, or the remote control operation unit 120 is connected. By providing the floor heating mat construction abnormality inspection device 30 inside, the signal line connection work is simplified and the efficiency of the inspection work can be increased.
[0058]
In the embodiment described above, inspection is performed by passing hot water through the pipe. However, the liquid is not limited to hot water as long as it has conductivity. Further, in the embodiment, both the presence / absence of penetration of a nail or the like and the case of not being penetrated but being driven close enough to damage the pipe are inspected based on the size of the electrostatic capacitance. Due to conduction, close-in driving may be inspected by capacitance.
