Description

Description: TECHNICAL FIELD The present invention relates to a suga leak preventing automatic control device for automatically preventing suga leak of a house in a snowy cold region.

[Prior Art] Generally, a large amount of snow 9 is generated on the roof of a house 10 or the like in a snowy cold region as shown in FIG. In the attic 11 of the house 10 or the like, a through-flow heat flow as shown by an arrow A is generated, and this through-flow heat flow heats snow on the roof to cause snow melting, which causes a roof surface as shown by an arrow B. A snowmelt stream flows down to the eaves section 12 side along.

In this case, when the outside air temperature is positive, the snowmelt water that has flowed down falls from the eave tip into the eaves gutter (not shown), passes through the vertical gutter (not shown), and into the drain ditch (not shown). leak. However, when the outside air temperature is negative, the snowmelt water that has flown down to the eaves section freezes, and as shown in Fig. 2, ice bank 13
To form. When the ice bank 13 grows to a certain height or more, the snowmelt water does not fall under the eaves and leaks into the attic 11 through the rain (not shown), causing a so-called suga leak phenomenon. It is said that this suga leakage phenomenon reduces the life of buildings in snowy countries by half, and if suga leakage occurs, the life of houses will be significantly reduced.

For this reason, even in the conventional technique, as a measure against suga leakage, a roof heater 6a, which is a snow melting means, is installed at the eaves end as shown in FIG. 3, and a temperature detecting means 4a is arranged in the vicinity thereof to control the temperature of the roof heater 6a. It prevented the formation of ice bank 13 at the eaves.

[Problems to be Solved by the Invention] However, in such a conventional suga leak prevention device, the roof heater 6a is energized at room temperature because it is necessary to always maintain the eaves tip portion at a positive temperature. Since such a roof heater 6a generally consumes about 300 watts of electricity per 1 m ^2, it is not only complicated and relatively expensive in control technology, but also very expensive in maintenance cost. There was a problem. Therefore, even if the equipment is bent, it is often not used, which has been a cause of a decrease in the penetration rate of this type of apparatus.

The present invention has been made in view of the above-mentioned conventional problems, and automatically and reliably prevents suga leakage, and can operate with low energy consumption and low maintenance cost. The purpose is to provide.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present application provides an electronic device that uses snow-melting means in the eaves and uses a temperature-sensitive resistor or a thermocouple as a sensor in the attic and the eaves. A temperature controller is arranged as a temperature detecting means, and a control means for automatically operating the snow melting means is provided only when the temperature of the attic is 0 ° C. or higher and the temperature of the eaves is 0 ° C. or lower. An automatic control device for preventing suga leakage is provided as a characteristic invention, and snow melting means is provided in the eaves, and the temperature detecting means is provided in the attic and the eaves, and the light emitting element and the light receiving element are provided on the roof as a single body. The diffuse reflection type optical sensor described above is provided as a detecting means for detecting snowfall, and the detecting means confirms the snowfall and the signal generated by the detecting means causes the temperature of the attic to be zero.
Provided as a related invention is a suga leak preventing automatic control device, which is provided with control means for automatically operating the snow melting means only when the temperature of the eaves portion is 0 ° C. or higher and 0 ° C. or lower.

[Operation] Therefore, the ice bank occurs only when the roof is covered with snow and the temperature of the back of the hut is positive and the temperature of the eaves is negative. Based on this principle, the temperature of the attic and the eaves are detected by the temperature detecting means, and the control means determines whether or not these measured values satisfy the above conditions, and only when the above conditions are satisfied. Work snow melting means. As a result, it is possible to prevent the occurrence of ice banks and reduce power consumption.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic explanatory view showing an embodiment of the present invention.

First, the configuration will be described. In the figure, 5 and 6 are roof heaters which are snow melting means installed on the back of the eaves and the roof surface corresponding to the eaves. The temperature detection means 3 and 4 for performing are installed. The attic 11 is provided with temperature detecting means 2 for detecting the temperature.

The temperature detecting means 2, 3 and 4 are respectively connected to the control means 1 and input the temperature detection signals detected at their respective locations. The roof heaters 5 and 6 are connected to the heating operation source 7,
The heating operation source 7 is controlled by the control means 1 to control the heating of the roof heaters 5 and 6. The control means 1 is an attic 11
The heating operation source 7 is operated only when the temperature detected by the temperature detecting means 2 is 0 ° C. or more and the temperature detected by the temperature detecting means 3, 4 is 0 ° C. or less.

Then, the snowmelt water flowing down along the roof as shown by the arrow B due to the heat generated by the temperature of the back of the cottage 11 becoming 0 ° C. or more is warmed to 0 ° C. or more by the roof heaters 5 and 6.
Therefore, the ice bank 13 is not formed in the eaves, so that the snowmelt water falls from the eaves and flows down to the drain. Further, when the temperature of the attic 11 drops at night and the amount of heat flowing through is reduced to a temperature of 0 ° C. or lower, the energization of the roof heaters 5 and 6 is stopped even if the eaves portion is 0 ° C. or lower. This is because there is little flow-through heat from the attic 11, so there is no generation of snowmelt water.
This is because the ice bank 13 does not occur as described above.

As described above, by energizing the roof heaters 5 and 6 only when there is a possibility that the ice bank 13 may be generated, the power consumption can be reduced as much as possible, which results in energy saving and maintenance cost of this type of device. It can be reduced significantly compared to the conventional one.

Further, reference numeral 8 shown in FIG. 1 is a detection means installed on the roof for detecting a snowfall state. The detection means 8 detects the state of the snow cover 9 on the roof and is connected to the control means 1. The energization control of the roof heaters 5 and 6 is based on the temperature detection values of the temperature detection means 3 and 4 as described above, but this control is naturally performed when the snow 9 is present on the roof. The detecting means 8 is for this purpose, and is for performing the control operation without loss. That is, the control means only when the detecting means 8 confirms the snow and the temperature detecting means 2, 3, 4 confirm that the temperature of the attic 11 is 0 ° C. or higher and the temperature of the eaves is 0 ° C. or lower. 1, the roof heaters 5 and 6 are energized.

Thus, in this embodiment, since the energization state to the roof heaters 5 and 6 is controlled according to the detected snow cover state, it is possible to more effectively prevent the suga leak.

In addition, although the example in which the roof heaters 5 and 6 are provided on the roof surface and the eaves eaves has been described in the above embodiment, the present invention is not limited to this. Further, as the snow melting means, the example in which the roof heaters 5 and 6 are applied has been described in the above embodiment, but the present invention is not limited to this. Further, the detection means 8 may be configured not only to confirm the snowfall 9 but also to detect the snowfall amount, the snowfall height, etc., and to generate a detection signal when the snowfall amount is a certain value or more.

[Effects of the Invention] As described above, according to the present invention, the snow melting means and the temperature detecting means provided in the eaves, the temperature detecting means provided in the attic, and the temperature of the eaves and the attic are used to melt the snow. Since the structure is provided with the control means for automatically controlling the means, it is possible to automatically and surely prevent the suga leak of the house, consume less power, and reduce the maintenance cost by saving energy. An effect that an automatic control device for preventing leakage of suga can be provided can be obtained.
