Further, a configuration is disclosed in which a dedicated fan is provided as a blower for preventing condensation in the room, and warm air near the ceiling is applied to the window by the dedicated fan. In these cases, the indoor side of the window is directly warmed and condensation can be prevented. However, in the former configuration, there are restrictions on the arrangement of the air conditioners. Moreover, in the latter structure, there exists a possibility of damaging the indoor external appearance.

  The window opening 13 includes an outer opening 21 formed in the outer plate 11, an inner opening 22 formed in the inner plate 12, and frame frames 23, 24, and 25 that constitute the peripheral edge of the window opening 13. And is formed by. The glass window 14 is slidably attached to the window frame sash 26 attached to the outer opening 21. The glass window 14 is configured by holding a glass plate 32 on a window sash 31.

  The outer plate 11 and the inner plate 12 are separated so as to form a predetermined internal space. As a result, the window opening 13 has a predetermined depth dimension, and the glass window 14 is in a position recessed from the inner plate 12 to the outdoor side.

  The lower frame 25 of the frames 23 to 25 is attached so as to protrude to the indoor side from the inner plate 12. On the other hand, the upper frame 23 and the vertically extending vertical frame 24 are attached such that the position of the indoor side end portion is on the outdoor side of the inner plate 12. A plurality of (three in this embodiment) corner covers 40a, 40b, and 40c are provided at the corners of the inner plate 12, the upper frame 23, and the vertical frame 24 so as to close the gaps between them. It is attached by.

  Each corner cover 40a-40c is formed by bending a metal plate such as aluminum. Specifically, each of the corner covers 40 a to 40 c connects the first contact portion 41 that contacts the inner plate 12, the second contact portion 42 that contacts the frame 23, 24, and both contact portions 41, 42. The connecting part 43 to be provided. The first contact portion 41 and the second contact portion 42 are both bent at a right angle, and the first contact portion 41 is a plate surface 12 a facing the outdoor side of the inner plate 12 and the peripheral surface of the inner opening 22. The second contact portion 42 is in contact with the plate surfaces 23a and 24a facing the outside of the window opening 13 in the frames 23 and 24 and the indoor side end surfaces 23b and 24b. Moreover, the connection part 43 is bent and formed in the circular arc shape so that it may become convex on the indoor side. The corner covers 40a to 40c are not limited to being made of metal, and may be made of synthetic resin.

  By providing the corner covers 40a to 40c, the gap between the inner plate 12 and each of the frame frames 23 and 24 is reliably closed, and the airtightness in the room is secured. Therefore, the entry and exit of heat inside and outside the room is suppressed. In addition, as shown in FIG. 3, the heat insulating material 15 is provided between the outer plate | board 11 and the inner plate | plate 12, and the entrance / exit of the heat | fever inside / outside is also suppressed from this point.

  Now, in this embodiment, the dew condensation prevention apparatus 50 of the glass window 14 is provided. Therefore, the dew condensation prevention device 50 will be described below.

  As shown in FIG. 3, a fan heater 51 as a blower is disposed in the internal space of the partition wall 10 and on the upper frame 23. The fan heater 51 includes a blower fan 52 that is driven by a drive unit (not shown) and a heater 53 that warms the wind sent out by the blower fan 52. In addition, although the heater 53 is comprised by the PTC heater which has a self-temperature control function, it is good also as a structure which uses another general purpose heater.

  Hot air from the fan heater 51 is blown out toward the indoor side surface of the glass plate 32 through the ventilation duct 55. Specifically, as described above, the connecting portions 43 of the corner covers 40a to 40c are formed to be bent in an arc shape so as to protrude toward the indoor side, and the respective contact portions 41 and 42 are provided in the corner covers 40a to 40c. And the accommodating part 44 is formed so that it may be divided by the connection part 43. FIG. Each accommodating part 44 is connected, and the ventilation duct 55 is accommodated in these accommodating parts 44. The ventilation duct 55 is provided over the entire corner covers 40a to 40c.

  A portion 42a facing the inside and outside of the second contact portion 42 in each corner cover 40a to 40c extends to the inside of the window opening 13 from the frames 23 and 24, and the extending portion 45 has a slit penetrating inward and outward. 46 is formed. A plurality of slits 46 are formed at equal intervals along the peripheral edge of the window opening 13.

  A plurality of ventilation openings 56 are formed in the ventilation duct 55 so as to correspond to the slits 46 on a one-to-one basis. The opening size of each vent 56 is substantially the same as the opening size of each slit 46. And each slit 46 of each corner cover 40a-40c has each ventilation port 56 of the ventilation duct 55 aligned, and the warm air blown from the fan heater 51 passes through the ventilation duct 55, and each ventilation port. 56 and each slit 46 are blown into the room. Since the extending portion 45 faces the glass window 14, the blown warm air hits the surface on the indoor side of the glass plate 32. As described above, a plurality of the slits 46 and the vent holes 56 are formed along the peripheral edge of the window opening 13, so that warm air can be blown out from a plurality of positions along the peripheral edge of the glass plate 32. In particular, according to this structure, warm air can be blown out toward the upper part and both sides of the glass plate 32.

  With the above configuration, the occurrence of condensation on the glass plate 32 can be prevented. In particular, since warm air is blown out, dew condensation can be prevented while suppressing temperature drop in the room. Furthermore, when the glass window 14 is cooled by the outside air, a cold draft phenomenon is assumed in which cold air is generated near the indoor side of the glass window 14 and this cold air flows toward the indoor floor. Since the glass window 14 and its periphery are warmed by warm air, the occurrence of a cold draft phenomenon can be suppressed.

  Here, the building in this embodiment is a unit building constructed by combining a plurality of building units, and each of the corner covers 40a to 40c and the dew condensation prevention device 50 described above are incorporated in the building unit in advance. Some building units have a plurality of glass windows 14. In this case, by using one fan heater 51 for each glass window 14, it is possible to prevent condensation while reducing costs.

  Next, ON / OFF control of the fan heater 51 will be described. That is, in this embodiment, the fan heater 51 is not always operated, but is ON / OFF controlled by the control device 60 according to the indoor environment.

  The control device 60 includes a well-known microcomputer including a CPU, various memories, and the like, and includes an input / output port. As shown in FIG. 3, an outside temperature sensor 61, an inside temperature sensor 62, and a humidity sensor 63 are connected to the input side of the control device 60. The outside temperature sensor 61 is arranged so as to detect the temperature around the indoor side of the glass window 14. The inside temperature sensor 62 is arranged so as to detect the temperature near the center of the room, and the humidity sensor 63 is arranged so as to detect the humidity near the center in the room. A fan heater 51 is connected to the output side of the control device 60. And the power supply of the fan heater 51 is turned ON / OFF when the control apparatus 60 performs ON / OFF control. By this ON / OFF, both the drive unit of the blower fan 52 and the heater 53 are turned ON / OFF.

  FIG. 4 is a flowchart showing ON / OFF control processing executed by the control device 60. This process is repeatedly executed at a predetermined cycle (for example, 1 sec).

  In FIG. 4, first, in step S11, detection data of the outer temperature sensor 61, the inner temperature sensor 62, and the humidity sensor 63 are acquired. Thereafter, in step S12, a calculation process is executed based on the acquired data. In this calculation process, the indoor water vapor pressure is calculated based on the map data indicating the relationship between the temperature stored in the memory of the control device 60 and the water vapor pressure, and further, the reference temperature for the occurrence of condensation with respect to the calculated water vapor pressure. Is calculated.

  FIG. 5 is a correlation diagram showing such map data. In this map data, the horizontal axis is set to temperature (° C.), the vertical axis is set to water vapor pressure (mmHg), and the value of saturated water vapor pressure for each temperature is stored (saturated water vapor in FIG. 5). Pressure line). When calculating the indoor water vapor pressure, first, the indoor temperature is determined from the detection result of the inner temperature sensor 62, and then the humidity is determined from the detection result of the humidity sensor 63. Then, the water vapor pressure in the room is calculated from the product of humidity with respect to the saturated water vapor pressure at the grasped temperature. For example, when the grasped temperature is 25 ° C., the saturated water vapor pressure is 23 mmHg, and when the grasped humidity in this case is 80%, the indoor water vapor pressure is calculated to be about 18 mmHg. Further, the temperature at which the calculated indoor water vapor pressure becomes the saturated water vapor pressure is calculated from map data, thereby calculating the reference temperature for occurrence of condensation. For example, when the calculated indoor water vapor pressure is 18 mmHg described above, the reference temperature is calculated to be 21 ° C.

  Returning to the explanation of the ON / OFF control process, after the calculation process is executed in step S12, it is determined in step S13 whether the power of the fan heater 51 is ON. When the power is not turned on, the start determination process of step S14 and step S15 is executed, and when the power is turned on, the end determination process of step S16 and step S17 is executed.

  In the start determination process, first, in step S14, it is determined whether or not the temperature grasped from the detection result of the outer temperature sensor 61 is the start reference temperature. Specifically, a temperature obtained by adding 1 ° C. to the reference temperature calculated in the calculation process is set as a start reference temperature. If the grasped temperature is equal to or lower than the start reference temperature, an affirmative determination is made in step S14, and if it exceeds the start reference temperature, a negative determination is made in step S14. If an affirmative determination is made, the start determination process ends after the power of the fan heater 51 is turned on in step S15. If a negative determination is made, the start determination process ends. In this way, the occurrence of condensation can be prevented by setting the temperature obtained by adding 1 ° C. to the reference temperature as the start reference temperature.

  In the end determination process, first, in step S16, it is determined whether or not the temperature grasped from the detection result of the outer temperature sensor 61 is the end reference temperature. Specifically, the temperature obtained by adding 2 ° C. to the reference temperature calculated in the calculation process is set as the end reference temperature. If the grasped temperature exceeds the end reference temperature, an affirmative determination is made in step S16, and if it is equal to or lower than the end reference temperature, a negative determination is made in step S16. If an affirmative determination is made, the end determination process is terminated after the power of the fan heater 51 is turned off in step S17. If a negative determination is made, the end determination process ends. In this case, the ON / OFF of the fan heater 51 is prevented from being repeated by setting the end reference temperature higher than the start reference temperature.

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

  A slit 46 as a blow-out opening is formed in a corner cover 40a to 40c provided so as to close a gap between the inner plate 12 and each of the frames 23 and 24, and a wind for preventing condensation is blown out through the slit 46. As a result, it is not necessary to provide the fan heater 51 as a blower in the room, and the configuration relating to blowing of wind for preventing condensation can be improved. Moreover, the said effect can be acquired, utilizing effectively the corner covers 40a-40c for improving airtightness. Furthermore, the above-mentioned effect can be obtained without impairing the air outlet in the room and impairing the appearance of the room.

  A wider area of the glass window 14 than the configuration in which the wind for preventing condensation is blown from one direction to the glass window 14 by blowing the wind for preventing condensation from a plurality of directions along the periphery of the glass window 14. The wind can be applied to the mist, and condensation can be prevented efficiently.

  By providing the ventilation duct 55 for guiding the wind from the fan heater 51 to the slit 46, the wind from the fan heater 51 can be reliably guided to the slit 46. In particular, since a plurality of slits 46 are formed, the air from the fan heater 51 can be reliably guided to each slit 46 by forming the vent 56 in the vent duct 55 so as to correspond to the slits 46. Further, since the ventilation duct 55 is accommodated in the accommodating portions 44 of the corner covers 40a to 40c, the ventilation duct 55 is not exposed in the room and the appearance of the room is not impaired.

  By forming the slit 46 so as to be separated from the glass window 14 on the indoor side, the wind blown from the slit 46 hits a wide area of the glass window 14, and condensation can be prevented efficiently.

  By providing the control device 60 and controlling the fan heater 51 to be ON when there is a risk of condensation, it is possible to prevent condensation while saving energy. Further, the outer temperature sensor 61, the inner temperature sensor 62, and the humidity sensor 63 are provided, and map data indicating the relationship between the temperature and the water vapor pressure is stored in the control device 60, thereby reliably predicting the occurrence of condensation. Therefore, it is possible to reliably prevent condensation.

  In addition, this invention is not limited to the description content of the said embodiment, For example, you may implement as follows.

In this case, the building 70 is provided with a plurality of glass windows W1, W2, and ventilation ducts 73e, 73f are provided so as to extend toward the upper peripheral edge of the glass windows W1, W2. And the wind guide | induced by the ventilation ducts 73e and 73f blows off toward glass window W1, W2, and dew condensation is prevented. That is, according to this configuration, the air blower 72 of the central ventilation device is also used as the air blower of the dew condensation prevention device, and central ventilation and prevention of dew condensation are achieved by the single air blower 72, thereby reducing costs. Both effects can be obtained while aiming. Moreover, the one air blower 72 is shared with respect to several glass window W1, W2, and cost reduction can be achieved also from this point.

And condensation is prevented. That is, according to this configuration, the hot water ducts 84 and 85 of the floor heating device are also used as heaters of the dew condensation prevention device, and it is possible to achieve both floor heating and prevention of condensation while reducing costs.

In the above embodiment, in order to execute the ON / OFF control process of the fan heater 51, the temperature around the indoor side of the glass window 14, the temperature inside the room, and the humidity inside the room are detected. Thus, a configuration may be adopted in which a dew condensation sensor is attached to the indoor surface of the glass plate 32 and the ON / OFF control process of the fan heater 51 is executed by directly detecting the occurrence of dew condensation.

  The controller 60 may be configured to perform ON / OFF control of the blower fan 52 and ON / OFF control of the heater 53 separately.
