Description

  The present invention relates to an anti-fogging device for a curved mirror and a curved mirror to which the device is attached. More specifically, the present invention relates to a device for removing dirt such as frost and water droplets adhering to the surface of a curve mirror installed on a road or street using natural energy, and a curve mirror to which the device is attached.

  Road safety is one of the most important issues for people's safe living. The modern automobile society is evolving more and more because of the convenience that cars bring, that is, the expansion of the range of action and the reduction of travel time. In addition, buses for public services and business vehicles are frequently operated and frequently used, and there are many traffic congestion points. Therefore, it is required to drive on the road as safely as possible. Also, today, curve mirrors are generally installed at roads and intersections on roads where there are many cars, such as in urban areas, for traffic safety. That is, curve mirrors are installed at curves and intersections with poor visibility. This is very helpful in preventing traffic accidents. Thus, the curve mirror is an important facility for traffic safety not only for the driver of the car but also for the pedestrian.

  The curved mirror has a surface on which dirt such as dust floating in the outside air is attached, and periodic cleaning thereof is indispensable. In particular, snow, water droplets, frost, and the like often adhere to the mirror mirror surface due to the influence of weather changes such as snow, rain, and wind. Such snow, water droplets, frost, etc. may freeze in winter and other temperatures below zero. When the temperature is suddenly lowered, snow, water droplets, frost, etc. may adhere to the convex mirror of the curve mirror, and the night dew may freeze, resulting in cloudiness. Curve mirrors are regularly inspected, wiped off dirt, and repaired by repairing damaged parts.

  However, dirt generated under such natural conditions covers the entire area, and maintenance every day, every hour, is impossible in terms of cost and human resources. There is a need to automatically clean the curved mirrors created under these natural conditions, or to take measures to prevent such stains. At the same time, air pollution such as car exhaust gas may adhere to the mirror surface, and countermeasures against this are also required.

  For example, Patent Document 1 and Patent Document 2 disclose an anti-fogging device for a curved mirror. The apparatus of Patent Literature 1 includes a blower installed at a position where air can be blown over the entire surface of the curve mirror, and an ultrasonic oscillator installed at a position where ultrasonic waves can be oscillated over the entire surface of the curve mirror. Towards the mirror surface, the ultrasonic wave is oscillated by the ultrasonic oscillator at the same time as the air is blown by the blower. The device of Patent Document 2 is connected to a circular 5 cm small heating panel attached to a curved mirror or attached to a curved mirror, by attaching a solar plate and a storage battery having a size of 5 cm to 10 cm to the additional mirror. The small mirror is heated by flowing weak electricity to prevent fogging of the curved mirror.

[First Embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a conceptual diagram showing a curve mirror anti-fogging device 1 according to a first embodiment of the present invention and a state in which the device is attached. FIG. 2 is a side view showing a state where the blower 2 of the anti-fogging device 1 for the curved mirror is attached to the curved mirror 10. As shown in FIG. 1, the anti-fogging device 1 for a curved mirror according to an embodiment of the present invention includes a blower 2, a power supply unit 3, and a basket 4. As shown in FIG. 3, the power supply unit 3 includes a solar power generator 5, a capacitor 6, a control unit 9, and the like.

  Further, as illustrated in FIG. 1, the curve mirror 10 is attached to the upper portion of the pillar 11 installed with the lower end portion buried in the ground by being detachably fixed by the attachment tool 12. The pillar 11 is usually disposed at the end of the road or the like. The curve mirror 10 usually has a small gavel 4a in many cases. The gavel 4a serves to protect the curve mirror 10 from wind and rain. The anti-fogging device 1 for a curved mirror according to the present embodiment has a gutter 4 that covers the upper part of the small gutter 4a. The collar 4 is detachably provided on an existing curve mirror and is attached on the curve mirror 10. The kite 4 serves to protect the curved mirror 10 from wind and rain, and at the same time serves to protect the blower 2 from wind and rain. In particular, it is effective in preventing rain and wind from above and from the side.

  The collar 4 is made of a rectangular plate-like material, and is placed on the upper periphery of the upper part of the curve mirror 10. The collar 8 on both sides of the collar 4 is attached to the rib part of the curve mirror 10 by a bolt / nut mechanism. It is fixed. However, as long as the bar clamp 8 can fix the bar 4 to the curve mirror 10, any known fixing mechanism can be used even if it is not a bolt / nut mechanism. The blower 2 is fixed to the upper part of the curve mirror 10 by a fixture plate 13. The ridge 4 is wider and longer than the small ridge 4a. The scissors 4 are installed so as to be detachable on the small scissors 4a. If there is a ridge 4, there is no need for the small ridge 4a. That is, it is also possible to simply remove the small rod 4a, which is also an accessory of the curve mirror 10, and attach the rod 4.

  As shown in FIG. 2, the installation position of the blower 2 is preferably one in which the blower 2 is disposed in a space surrounded by the flange 4 when the curved mirror 10 is viewed from the side. More precisely, the blower 2 may be arranged in a space surrounded by the front outer edge of the ridge 4 and the mirror surface of the curve mirror 10. The reason for this is to prevent wind and rain from above the blower 2 and from both sides. Further, since the fan 4 surrounds the blower 2 by dividing the space, it plays the role of flowing air from the blower 2 only in the downward direction at the same time as avoiding wind and rain to the curve mirror 10. The wind and rain from the side can be prevented, and the disturbance of the blower 2 can be prevented.

  In the example of FIGS. 1 and 2, the air blown by the blower 2 basically flows from the top to the bottom, and is easily affected by wind from the side. The influence of this side wind is shielded with 庇 4. The attachment plate 13 is mounted and fixed on the upper part of the ridge 4 in accordance with the position of the middle of the curved mirror 10 from the front (front) of the ridge 4. As shown in FIG. 2, the fixture plate 13 is fixed to the mirror surface of the curve mirror 10 so as to have a predetermined angle θ from the horizontal. The upper part of the fixture plate 13 is disposed at a right angle to the curve mirror 10. Since the upper part of the attachment plate 13 is arranged in the horizontal direction, the lower part of the attachment plate 13 to which the blower 2 is fixed is fixed so as to have an angle θ.

  In other words, the air blowing direction by the blower 2 is fixed so as to have an angle of “90−θ” degrees with respect to the tangent to the surface of the curve mirror 10 passing through the center point of the surface of the curve mirror 10. The blower 2 is basically fixed at a position where air can be blown over the entire mirror surface of the curve mirror 10. The blower 2 is basically installed at the upper part of the center of the surface of the curve mirror 10 depending on the characteristics of the place where the curve mirror 10 is installed, the wind direction, and the like. In other words, the blower 2 is installed at a position where the entire surface of the curve mirror 10 can be blown. The blower 2 blows air toward the surface of the curve mirror 10.

  As shown by the arrows in FIG. 2, the blowing direction from the blower 2 is set near the center of the surface of the curved mirror 10 and toward the upper and lower regions thereof. The width | variety of the gutter 4 is a width | variety which prevents the whole air blower 2 from a wind and rain. Since the eaves 4 are installed along the outer edge of the curve mirror 10, they are bent in conformity with the shape of the curve mirror 10. As described above, the area defined by the outer edge of the ridge 4 and the mirror surface of the curve mirror 10 is a three-dimensional space. The blower 2 is installed in this space. In other words, the blower 2 is installed in a space defined by the outer edge of the basket 4 and the mirror surface of the curve mirror 10.

  The power supply unit 3 is fixed on the curve mirror 10 in the example of FIG. The power supply unit 3 is fixed by fixing means 14. The fixing means 14 is for fixing the power supply unit 3 to the curve mirror 10 or the column 11 with bolts, nuts or the like. Any known fixing means 14 may be used as long as the front face of the power supply unit 3 can be adjusted and fixed at a position where the sunlight hits most. A solar power generator 5 is provided in front of the power supply unit 3. The solar power generator 5 converts sunlight into electricity and is a solar battery panel. A power storage unit 6 and a control unit 9 are stored in the casing of the power supply unit 3.

  The housing of the power supply unit 3 serves to prevent and protect against failure of the device housed therein. The blower 2 is operated by electric power from the battery 6. The battery 6 stores the power generated from the solar power generator 5. The battery 6 is charged until it reaches a predetermined charge capacity, and then supplies power to the blower 2 and the like. While the solar power generator 5 is generating power, power is directly supplied to the blower 2 from the solar power generator 5. When the amount of power generated by the solar power generator 5 is small or when power cannot be generated, power is supplied from the battery 6 to the blower 2.

  The operation of the power supply unit 3 includes, for example, the following operation method. During the day, the blower 2 is operated while generating power with the solar power generator 5 and charging the battery 6. At night, since the solar power generator 5 does not generate power, the power is supplied from the capacitor 6 to the blower 2 to operate the blower 2. In this way, the “fogging” on the surface of the curve mirror 10 is automatically removed by the blowing from the blower 2. The anti-fogging device 1 for the curve mirror can also operate or stop the blower 2 depending on weather conditions. At this time, as shown in FIG. 4, the anti-fogging device 1 for the curve mirror includes a temperature sensor 16 for detecting the temperature and a wetting sensor 15 for detecting the humidity of the atmosphere. The temperature sensor 16 and the wetness sensor 15 are well-known sensors, and description thereof is omitted here.

  The temperature sensor 16 and the wetness sensor 15 output the detected signal to the control unit 9. The temperature sensor 16 and the wetness sensor 15 are stored in the power supply unit 3. The “fogging” on the surface of the curve mirror 10 is automatically removed by blowing air from the blower 2. The “cloudiness” referred to here refers to the cloudiness that occurs in the following cases. First, it refers to cloudiness when clouding occurs due to snow, frost, etc. adhering to the surface of the curve mirror 10 due to a natural phenomenon such as a sudden drop in the atmospheric temperature, or night dew freezes. In other words, it refers to cloudiness when the surface of the curve mirror 10 is blown by rain and winds and becomes wet and forms water droplets.

  In short, the “cloudiness” of the surface of the curve mirror 10 means that the surface of the curve mirror 10 is difficult to visually recognize due to weather conditions. Such cloudiness due to weather conditions often occurs, for example, in cold regions and regions with high altitudes, particularly from late autumn to winter. Although the surface of the curved mirror 10 is soiled by an artificial act is not basically targeted in the present embodiment, the artificial dirt is cleaned by the air blown from the blower 2. In other words, the degree thereof can be reduced, and contamination can be prevented.

  In addition, artificial dirt and dirt caused by air pollution and the like can be cleaned, reduced, and prevented by the blower 2 of the present embodiment. As described above, the anti-fogging device 1 of the curved mirror according to the present embodiment is called automatic frost avoidance, rain water drop removing device, automatic dirt removing device, automatic stain preventing device, automatic fog preventing device, etc. You can also. The blower 2 can be any known blower. For example, a small electric fan is used as the blower 2. The blower 2 blows air over the entire mirror surface of the curved mirror 10 as indicated by arrows in FIGS. 1 and 2.

  The power storage device 6 can use any power storage device as long as it can store the power obtained from the solar power generator 5. For example, a lead battery, a lithium ion battery, a lithium ion polymer battery, a nickel / cadmium storage battery, or the like can be used as the battery 6. These batteries are particularly preferably secondary batteries when used repeatedly. The power cord 17 connects the blower 2 and the power supply unit 3. The solar power generator 5 of the present embodiment can use any known solar cell (solar battery) as long as it can convert sunlight into electrical energy.

  The solar power generator 5 illustrated in FIG. 1 is a solar power generation module including a panel including one or more cells that convert sunlight into electric energy. The solar power generator 5 is for charging the battery 6 with the solar power generator 5. Moreover, when the solar power generator 5 is used, when the sunlight is weak, the blower 2 can be operated by the capacitor 6 at night when there is no sunlight. When there is sunlight, the blower 2 can be operated only by the solar power generator 5. Moreover, when sunlight is weak, the air blower 2 can be operated with the output of both the solar power generator 5 and the battery 6.

  Based on the signals detected by the temperature sensor 16 and the wetness sensor 15, changes in the outside air temperature and wetness of the curve mirror 10 can be automatically captured. The control unit 9 analyzes the signals detected by the temperature sensor 16 and the wetness sensor 15 to analyze the situation, and controls the operation of the blower 2. As shown in FIG. 2, the blower 2 is installed on the lower surface of the ridge 4 (inside the ridge) and at a position where air can be sent to the entire convex mirror of the curve mirror 10. The blower 2 is fixed by mechanical fixing means in the present embodiment, but may be fixed to the lower inner side of the flange 4 by an adhesive. It is desirable to install the solar power generator 5 so as to face the longest daylight hours throughout the year.

[Configuration of Control Unit 9]
FIG. 4 is a block diagram schematically showing the internal circuit of the control unit 9 of the anti-fogging device 1 for a curved mirror. The control unit 9 is a device for controlling the entire anti-fogging device 1 for the curve mirror. As shown in the figure, a solar power generator 5 and a capacitor 6 are connected to the control unit 9. Furthermore, the temperature sensor 16, the wetness sensor 15, and the blower 2 are connected to the control unit 9. The control unit 9 includes a central processing unit 20, a memory 21, and interfaces 2i, 5i, 6i, 15i, and 16i for each device.

  The central processing unit 20, the memory 21, each interface, and the like exchange signals via the bus 22. The memory 21 stores a control program for controlling the control unit 9. The control program is basically an algorithm written in machine language. The function of this control program can be realized by an analog or digital circuit. This program can be rewritten or updated by exchanging the memory 21 via a communication interface (not shown). The memory 21 is preferably a non-volatile memory or a rewritable memory.

  The blower 2 is electrically connected to the control unit 9, and power supply is received from the battery 6 and / or the solar power generator 5 via the control unit 9. Therefore, the control unit 9 can operate or stop the blower 2 at any time. The battery 6 is connected to the solar power generator 5 and the blower 2 via the interface 6i. The control unit 9 can connect or disconnect each of the solar power generator 5 and the blower 2 to the capacitor 6 by controlling these interfaces 2i, 5i, and 6i.

[Operation Flowchart of Control Unit 9]
The operation of the control unit 9 and the outline of the operation of the control program will be described below with reference to the flowchart of FIG. As a power source, a solar power generator 5 and a capacitor 6 are used. Electric power is supplied by the solar power generator 5 (step 1). With this electric power, the control unit 9 operates or charges the battery 6 (steps 2 and 3). The battery 6 can be composed of a plurality of battery cells. In this case, the control unit 9 can monitor and control individual cells individually. When the battery 6 has a control circuit therein, the control unit 9 controls the entire battery 6.

  By this charging, a power source necessary for the operation of the apparatus can be secured. The control unit 9 starts full-scale operation (step 4). The control unit 9 receives the humidity signal detected by the wetness sensor 15 (step 5). This humidity signal is compared with the set humidity value in the memory 21 (step 6). When the humidity signal indicates a value higher than the set humidity value, the blower 2 is operated (Step 7 and Step 8). Thereby, fogging of the curve mirror 10 can be prevented. The temperature sensor 16 senses the temperature around the curve mirror 10. When the humidity signal does not indicate a value higher than the set humidity value, the control unit 9 stops the operation of the operating blower 2 (Step 7 and Step 9).

  In this case, when there is no fan 2 which is operating, the process proceeds to the next process (to step 10). The control unit 9 receives the temperature signal detected by the temperature sensor 16 (step 10). The temperature signal output from the temperature sensor 16 is input to the control unit 9. The control unit 9 receives the temperature signal from the temperature sensor 16 and compares it with the set temperature value stored in the memory 21 (step 11). When the temperature signal is larger than the set temperature value, the blower 2 is stopped (steps 12 and 13).

  For example, when the temperature reaches a set value (for example, 0 °), the blower 2 is operated. In this case, when there is no fan 2 that is operating, the following processing is performed. When the temperature signal is equal to or smaller than the set value, the control unit 9 operates the blower 2 (step 14). Then, the control unit 9 proceeds to the next process (step 15). At this time, the control unit 9 monitors a device connected to the control unit 9. Then, the control unit 9 receives the humidity signal from the wetness sensor 15 (Step 15 and Step 5). Then, the same processing as described above is repeated.

  Thus, the control unit 9 can prevent fogging of the curve mirror 10 by operating the blower 2 at a predetermined humidity or temperature. The temperature and humidity at which the curve mirror 10 is cloudy are measured again, and the values are input to the control unit 9 in advance as set temperature values and set humidity values. The control unit 9 compares the sensed temperature signal and humidity signal with the set temperature value and set humidity value, and determines whether to operate or stop the blower 2. When the temperature rises or falls, or when rain or wind is generated or subsides, the control unit 9 detects the situation by the temperature sensor 16 and the wetness sensor 15 and operates or stops the blower 2. Become.

  The control unit 9 has a function of monitoring the charging state of the battery 6 in addition to the above-described operation. When the battery 6 is fully charged, the control unit 9 disconnects the solar power generator 5 from the battery 6. The control unit 9 can receive power supply from the solar power generator 5. The control unit 9 monitors the operation status of the solar power generator 5, determines the power supply destination of the control unit 9 itself and the power supply destination of the battery 6 according to the power generation status, and sets them optimally.

  As described above, the control unit 9 is realized as a micro electronic computer using the central processing unit 20 and the memory 21. The control unit 9 can be realized by an analog circuit or a simple digital circuit as long as it realizes the above-described operation and has the same function. For example, it can be realized by using a relay, a comparator, an amplifier, an LSI, and other electronic elements. Thus, the power supply unit 3 has a very simple structure in which the solar power generator 5 is installed in the front, and the control unit 9 and the capacitor 6 are housed in the casing.

  Only the power cord for connecting the blower 2 comes out of the casing of the power supply unit 3. This is easy to install in construction work. The collar 4 is made of a material that can be bent easily, such as plastic, and can be easily attached according to the shape of the curve mirror 10. In the present embodiment, the collar 4 is made of a transparent plastic material. If the ridge 4 is transparent, there is an advantage that the curve mirror 10 can be seen from the side of the curve mirror 10. In the present embodiment, only the round-shaped curve mirror 10 is illustrated, but the curve mirror 10 can have a shape such as a rectangle. Even in this case, since the collar 4 is flexible, it can be easily attached.

[Second Embodiment]
The second embodiment of the present invention will be described below with reference to the drawings. FIG. 6 is a conceptual diagram showing the anti-fogging device 101 for a curve mirror according to the second embodiment of the present invention and how it is attached. The curve mirror anti-fogging device 101 according to the second embodiment of the present invention includes a seat heater 18. Instead of the blower 2 according to the first embodiment of the present invention, the sheet heater 18 is used to automatically remove “fogging” on the surface of the curve mirror 10. The curve mirror anti-fogging device 101 according to the second embodiment of the present invention is basically the same in configuration and operation as the anti-fogging device 1 of the curve mirror according to the first embodiment of the present invention except for the seat heater 18. Here, only different parts are described.

  The power supply unit 3 is fixed to the pillar 11 with a fixture 12. The seat heater 18 is operated by electric power from the battery 6 and / or the solar power generator 5. The power cord 17 connects the seat heater 18 and the power supply unit 3. The control unit 9 supplies power to the seat heater 18 when the value detected by the two leak sensors -15 and the temperature sensor 16 or by either the leak sensor -15 or the temperature sensor 16 falls below a predetermined value. Then, the seat heater 18 is heated. By this heating, fogging of the surface of the curve mirror 10 is removed. The seat heater 18 can be of any operating principle as long as it heats. For example, it can be a conductor that is heated by power supply. The heating wire used for the rear window of the automobile can be used as the seat heater 18.

[Other Embodiments]
In the first embodiment of the present invention, air is blown to the curve mirror 10 using only the blower 2. In the second embodiment of the present invention, the curved mirror 10 is heated using the seat heater 18. The anti-fogging device for a curved mirror that combines both of these can be provided. For example, when the blower 2 blows air on the surface of the curve mirror 10, the air is heated by the seat heater 18, and warm air is blown on the surface of the curve mirror 10. In other words, air is heated by the seat heater 18, and the heated air is blown to the surface of the curve mirror 10 by the blower 2. When the anti-fogging device for a curved mirror having such a configuration is used, the anti-fogging of the curved mirror 10 can be removed faster than using only the blower 2 or only the seat heater 18.

  The present invention is preferably used for curved mirrors installed on roads and streets. In particular, it may be used to prevent fogging of the curve mirror when it becomes cloudy due to weather changes or natural conditions, and when there is such a sign.
