Here, the procedure for attaching the floor parting material 60 will be described with reference to FIGS. FIG. 4 is an explanatory diagram for explaining a procedure for attaching the floor parting material 60. In FIG. 4, the waterproof member 87 is not shown.

  As shown in FIG. 4A, a floor finishing material 58 a having a thickness smaller than that of the floor finishing material 58 is placed on the floor base material 57 in the floor portion 56. The thickness of the floor finishing material 58a is slightly smaller than the distance between the floor base material 57 and the lower frame extending portion 46, and the floor finishing material 58a is formed of the floor base material 57 and the lower frame extending portion 46. Between. Thereby, the parting part of the floor finishing material 58a is covered with the lower frame extending part 46 (sash frame 31).

  Then, as shown in FIG. 4B, the floor finishing material 58a is removed along with the renovation, and the floor finishing material 58 is replaced with the floor finishing material 58 in place of the floor finishing material 58 as shown in FIG. 4C. Place on top. Then, as shown in FIG.4 (d), while setting the heating wires 71-73 between the floor side insertion part 62 and the sash side insertion part 63 of the floor parting material 60, the upper partition part 82 and lower side Electrical wiring 84 is disposed between the partition portion 83 and the partition portion 83. In addition, when the length dimension of the insertion parts 62 and 63 of the floor parting material 60 is larger than the thickness dimension of the floor finishing material 58, the lower end side of the insertion parts 62 and 63 is cut and the lengths of the insertion parts 62 and 63 are cut. The height dimension is adjusted to be the same as the length dimension of the floor covering 58. For this reason, the floor parting material 60 can be attached corresponding to the floor finishing material 58 having various thickness dimensions. Thereafter, as shown in FIG. 2, the floor parting material 60 is attached to the boundary between the floor finishing material 58 and the sash frame 31.

  The floor finishing material 58a is removed and the floor parting material 60 is installed on the lower frame part 37 and the floor base material 57 of the sash frame 31, and then the end of the floor finishing material 58 is parted of the floor parting material 60. The floor parting material 60 may be attached by the procedure of placing the floor finishing material 58 on the floor base material 57 while being inserted between the plate portion 61 and the floor base material 57.

  In the present embodiment, heating control of the heating wires 71 to 73 is executed by the floor heating system. Here, the electrical configuration of the floor heating system will be described.

  As shown in FIG. 1, in the floor heating system, a controller 91 as a control unit includes a microcomputer including a CPU and various memories, and is attached to an inner wall surface of the living room 11, for example.

  The controller 91 includes a room temperature sensor 92 as an indoor temperature detecting means for detecting the temperature in the living room 11, an outside air temperature sensor 93 for detecting the outdoor temperature, and a sash frame temperature detecting means for detecting the temperature of the sash frame 31. And a sash water sensor 95 as dew condensation water detecting means for detecting whether or not water is attached to the sash frame 31, and these sensors 92 to 95 detect detection signals. Output to the controller 91. The room temperature sensor 92 is attached to the inner wall surface of the room 11, and the outside air temperature sensor 93 is attached to the outdoor side of the rail portion 42 in the lower frame body 41. The sash frame temperature sensor 94 is attached to the indoor surface of the lower frame standing part 45 of the lower frame part 37, and the sash water sensor 95 is attached to the room 11 side of the rail part 42 in the lower frame body 41. In this case, since the sash frame temperature sensor 94 is located below the lower frame extension 46 and the floor parting material 60, the sash frame temperature sensor 94 is not visually recognized by the person from the living room 11.

  In addition, when the part exposed to the room 11 side, such as the vertical frame part 35 of the sash frame 31, is formed with the synthetic resin material, the room temperature sensor 92 may be attached to that part. This is because the thermal conductivity of the portion exposed to the living room 11 side is low, and the temperature change in that portion is less dependent on the outside air temperature.

  The controller 91 is connected to a power supply device 78 and an operation device 96 for performing an input operation by a person. The power supply device 78 is installed, for example, in an underfloor space, and the controller 91 controls the operation of the power supply device 78 by outputting a command signal. The power supply device 78 can perform power supply individually for each of the heating wires 71 to 73. The operation device 96 is attached to the inner wall surface of the living room 11 and outputs an operation signal corresponding to the input operation to the controller 91.

  The controller 91 performs floor heating control for heating the floor portion 56 with the heating wires 71 to 73. Here, the processing procedure of the floor heating control process will be described with reference to the flowchart of FIG. The floor heating control process is repeatedly executed at a predetermined cycle.

  In FIG. 5, in step S <b> 11, it is determined whether or not condensation has occurred in the sash frame 31. Here, based on the detection signal of the sash water sensor 95, it is determined whether or not water is attached to the lower frame portion 37 of the sash frame 31. If water is attached, it is determined that condensation has occurred. If condensation has not occurred, the temperature of the room 11 is acquired based on the detection signal of the room temperature sensor 92 in step S12, and the sash frame 31 is determined based on the detection signal of the sash frame temperature sensor 94 in step S13. Get the temperature.

  In step S14, a temperature difference between the living room 11 and the outside is calculated, and it is determined whether or not the temperature difference is greater than a first determination value (for example, 10 ° C.). When the temperature difference is larger than the first determination value, the process proceeds to step S15, and the outside air temperature is acquired based on the detection signal of the outside air temperature sensor 93. In step S16, a temperature difference between the living room 11 and the sash frame 31 is calculated, and it is determined whether or not the temperature difference is greater than a second determination value (for example, 10 ° C.). The first determination value and the second determination value may be set to the same numerical value, or may be set to different numerical values.

  When the temperature difference between the living room 11 and the outdoor is larger than the first determination value, but the temperature difference between the living room 11 and the sash frame 31 is equal to or smaller than the second determination value, the process proceeds to step S17 and the first of the heating wires 71 to 73 Only the two heating wires 72 are supplied with power from the power supply device 78. In this case, the lower part of the vertical frame part 35 in the floor parting material 60 is heated by the heating part 75 of the second heating wire 72, and the vertical frame part 35 is warmed by the rising airflow rising along the vertical frame part 35. Thereby, the dew condensation of the vertical frame part 35 is suppressed intensively, and energy saving can be achieved compared with the case where the dew condensation of the window part 13 whole including the window glass 51 is suppressed.

  When the temperature difference between the living room 11 and the outdoor is larger than the first determination value and the temperature difference between the living room 11 and the sash frame 31 is larger than the second determination value, the process proceeds to step S18 and the first of the heating wires 71 to 73 is changed. Electric power is supplied from the power supply device 78 to the second heating wire 72 and the third heating wire 73. In this case, the floor parting material 60 below the entire sash frame 31 is heated by the respective heating portions 75 of the second heating wire 72 and the third heating wire 73, and the entire sash frame 31 and the window glass 51 are all ascended. Is warmed by. Thereby, the dew condensation generation | occurrence | production of the sash frame 31 and the window glass 51 is suppressed in the window part 13 whole. In this case, since the temperature difference between the living room 11 and the sash frame 31 is less than or equal to the second determination value (when proceeding to step S17), condensation is likely to occur. It is preferable to suppress the occurrence of condensation.

  When dew condensation has occurred in the sash frame 31 (when step S11 is NO), the process proceeds to step S19, and power is supplied from the power supply device 78 to all the heating wires 71 to 73. In this case, compared with the case where the floor parting material 60 is heated by the respective heating parts 75 of the second heating wire 72 and the third heating line 73, the floor parting material 60 is equivalent to the heating part 75 of the first heating wire 71. The temperature is raised. Thereby, the dew condensation water adhering to the sash frame 31 can be easily evaporated. That is, it becomes easy to remove condensed water.

  In the floor heating control process, the processes in steps S12 to S18 correspond to the first stage control, and the process in step S19 corresponds to the second stage control.

  Further, when the controller 91 receives an operation signal from the operation device 96, the controller 91 controls the operation of the power supply device 78 based on the operation signal. In this case, for example, if the operation signal is to heat each of the heating portions 75 of the heating wires 71 to 73, the power supply device 78 supplies power to each of the heating wires 71 to 73, and the heating is stopped. If the operation signal indicates, the power supply is stopped. In summer, the power supply from the power supply device 78 is stopped.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  By providing the heating wires 71 to 73 using the floor parting material 60, the heating wires 71 to 73 can be easily made by using the space between the lower frame portion 37 of the sash frame 31 and the outdoor side end portion of the floor finishing material 58. Can be installed. In this case, the heating wires 71 to 73 are provided at a parting portion (boundary portion) between the window portion 13 and the floor portion 56, and are suitable for heating the lower frame portion 37 of the sash frame 31. Therefore, generation | occurrence | production of the dew condensation in the window part 13 can be suppressed suitably.

  Each of the heating wires 71 to 73 has a heating portion 75, and the arrangement of the heating portions 75 is different for each of the heating wires 71 to 73. Therefore, the heating wires 71 to 73 to be supplied from the power supply device 78 are used. By selecting, the object of dew condensation suppression can be switched between the entire window portion 13 and a part thereof. Therefore, even if the sash frame 31 and the window glass 51 of the sash door 32 and the glass support frame 52 of the sash door 32 have different conditions of dew condensation due to differences in materials and the amount of solar radiation, etc. Therefore, by causing the heating wires 71 to 73 to perform a heating operation that is preferable, the occurrence of condensation can be suitably suppressed.

  For example, by heating the heating portion 75 of the second heating wire 72, the vertical frame portion 35 of the sash frame 31 in the window portion 13 can be warmed more than the window glass 51, and the occurrence of condensation can be suppressed. . In this case, the portion of the glass support frame 52 of the sash door 32 that is in contact with the vertical frame portion 35 is preferentially warmed to suppress the occurrence of condensation.

  Therefore, the energy consumption required for heating, such as the electric power supplied to the heating wires 71-73, can be reduced by switching the heating location of the floor parting material 60 as needed.

  Since heating of the floor parting material 60 by the heating wires 71 to 73 is electrically controlled by the controller 91, control of heating and non-heating becomes easy. That is, it becomes easy to heat the floor parting material 60 only when the conditions for the occurrence of condensation are satisfied. Therefore, energy saving can be achieved when dew condensation is suppressed.

  In the floor parting material 60, the heating wires 71 to 73 are surrounded by the parting plate portion 61, the insertion portions 62 and 63, and the connecting portion 86 so that the heating wires 71 to 73 can be prevented from being damaged. Moreover, in the configuration in which the heating wires 71 to 73 are inserted between the floor finishing material 58 and the sash frame 31 together with the insertion portions 62 and 63 when the floor parting material 60 is attached, the heating wires 71 to 63 are inserted between the insertion portions 62 and 63. Since 73 is arranged, it can be avoided that the heating wires 71 to 73 come into contact with the floor finish 58 and the sash frame 31 and are damaged as the insertion portions 62 and 63 are inserted. In other words, it is possible to avoid the heating wires 71 to 73 from being damaged in the state in which the floor parting material 60 is attached and also during the work of attaching the floor parting material 60.

  Since the electrical wiring 84 is disposed between the upper partitioning portion 82 and the lower partitioning portion 83 on the opposite side to the heating wires 71 to 73 across the sash side insertion portion 63 in the floor parting material 60, The wiring 84 can be protected by the partition portions 82 and 83 and the sash side insertion portion 63. Therefore, it is possible to avoid the electrical wiring 84 from being damaged in the same manner as the heating wires 71 to 73. In addition, since the lower partition 83 is provided below the electrical wiring 84, the electrical wiring 84 is damaged when the insertion portions 62 and 63 are inserted between the floor finish 58 and the sash frame 31. This can be avoided by the lower partition 83. Furthermore, since the electric power is supplied to the heating wires 71 to 73 through the electric wiring 84, it is possible to avoid that the electric wiring 84 is damaged and the electric power supply to the heating wires 71 to 73 is stopped.

  When the condensed water adheres to the sash frame 31, it can be heated by the heating wires 71 to 73 so that the temperature of the floor parting material 60 becomes higher than the case where the condensed water does not adhere. It can be removed by evaporation. In this case, the condensation removal is promoted in addition to the condensation suppression, and it is possible to avoid the floor base material 57 and the floor finish 58 from being damaged by the condensed water.
