  In winter and cold regions, water pipe freezes, roads, passages, freezing snow, etc. always occur due to lower freezing temperatures, so not only the use of tap water but also civil and transportation road accidents frequently occur. As a result, there are many obstacles to daily life, traffic congestion, and paralysis of urban functions.

  First, in the case of water pipe freezing, melting ice with an electric heater takes time and consumes a lot of power, and there is also a risk of fire in the building due to the use of heating wires for a long time.

  In addition, when the road surface (including runways and pavements, abbreviated below) and ice-burn conditions due to freezing of the passage surface and snow pressure, people and vehicles slip frequently and start at intersections and slopes. There is a traffic jam.

  On the other hand, automobile windows (including airplanes, railway cars, and building windows; hereinafter abbreviated), especially the front and rear window glass surfaces (including side windows. The wiper operation at high speed is necessary due to a large amount of snowfall and the severity of the rain, so that the load on the wiper body and the drive motor for the wiper increases, and the wiper wears out and the drive motor breaks down.

  Moreover, the high speed operation of the wiper during driving and the failure of the drive motor not only stain the glass surface and reduce or obstruct the driver's field of view, but also inhibit nerve concentration in driving.

  In order to solve the above-mentioned problems, the present invention first involves freezing the water pipe with one handle of a scissors-like ultrasonic water pipe melting device (including an instrument, hereinafter omitted) that can be gripped like a pliers. Ultrasonic vibrator (Languban type vibrator (PZT element), crystal vibrator and other piezoelectric element vibrators. The following is omitted.) Is incorporated in the part, and an arcuate tip tool ( A titanium alloy or a stainless alloy (hereinafter abbreviated) is attached so that ultrasonic acceleration and vibration energy can be directly transmitted.

  As this action, the acceleration and vibration energy of ultrasonic waves are directly transmitted to the frozen water pipe through the tip tool, and the activity of ice molecules inside the water pipe is excited, and frictional heat and vibration heat are generated to melt the ice. At the same time, the cavitation effect works even in the part of the tap water that is melting, and the melting is accelerated.

  Next, on the road surface, the ultrasonic transducer attached with a horn (including a booster, hereinafter abbreviated) is rounded from the center (hexagonal and It is arranged toward the front (including Happo), and a road end tool (titanium alloy or stainless alloy; hereinafter abbreviated) is attached to the tip (outer periphery), and these are attached to a titanium alloy or the like (such as a stainless alloy). , An aluminum alloy and a hard resin material (hereinafter abbreviated)), an ultrasonic ice-melting and snow-melting device integrally formed in a circular shape with a protective body is embedded in the center of the road, and ultrasonic waves are emitted horizontally and in all directions. By traveling through the asphalt, it is possible to melt the ice and compressed snow on the road surface where the above-mentioned energy is frozen.

  In addition, an ultrasonic road surface ice melting and snow melting apparatus (hereinafter referred to as “ultrasonic mat”) in which a small number of ultrasonic vibrators are incorporated in a flat plate shape of a semi-rigid resin material in front of a doorway in a residential area or a garden path. By laying on the road surface, the frozen road surface and snowfall can be melted.

  On the other hand, in the automobile window part, a small circular ultrasonic vibrator is integrated with soft resin and soft adhesive on the outer glass surface of the part where the front and rear window glass are supported and fixed at the lower part by elastic rubber etc. Glue and protect the ultrasonic car window ice melting and snow melting equipment protected by making it safe.

  This can not only prevent and remove the adhesion of ice, heavy rain and snow on the outside glass surface by crushing, flipping and melting with the above-mentioned energy, but also failure of the wiper and its drive motor. The driving field of view can be secured by reducing the dirt on the glass surface.

  In addition, a better effect can be obtained by using an ultrasonic ice melting and snow melting cable in which small circular ultrasonic transducers are connected in a cable shape on the water pipe, road surface, and passage surface.

  As described above, according to the present invention, in a water pipe, a conventional electric heater that has been heated and kept warm by wrapping a heating wire for a long time is a heat generation effect and a cavitation effect due to ultrasonic acceleration and vibration energy. As a result, the melting that has been proceeding from the contact surface of the heating wire until then is transmitted to all of the ice molecules almost simultaneously within a certain range, so that it is effective immediately and the power consumption is reduced.

  In addition, because it uses ultrasonic waves without using any heating wire for melting ice, it can completely eliminate the dangers of fires when using the heating wire for long periods of time and when heating, and it keeps the heating wire for heat insulation to prevent freezing. Therefore, it is possible to reliably increase the safety of human burns and fires to buildings.

  Next, on the road surface, conventional ice melting and snow melting is performed by laying heating wires under the surface of intersections and pavements on slopes as road heating, but this requires enormous power consumption. It has been constructed only at a limited point.

  Therefore, in the present invention, the acceleration and vibration energy of ultrasonic waves pass through solid asphalt having high conductivity and excite the molecular activity of ice and snow on the road surface, thereby generating frictional heat and vibrational heat, Since snow melting is performed, it is possible to simultaneously reduce power consumption by greatly reducing the heating area required for the conventional heating wire and reducing power consumption by shortening the energization time.

  In addition, the ultrasonic mat for the passage surface is not only effective in reducing the power consumption in the same manner as the conventional snow melting mat with heating wire, but also for people and pets such as dogs during melting and snow melting. However, since no heating wire is used, the risk of burns can be completely eliminated.

  On the other hand, in winter and cold regions, the front and rear window glass became frozen or hard snow when the car was started, and it was difficult to remove with a wiper, so it had to be melted manually or with a heater.

  In addition, when a car is running, a large amount of snow or rain causes a high load on the wiper, so the wearer damage to the wiper and the failure of the drive motor do not occur frequently. Had a great hindrance to safe driving.

  Therefore, as in the case of the automobile window of the present invention, as described above, freezing and hard snow are removed by directly and instantaneously transmitting ultrasonic acceleration and vibration energy to the automobile window, particularly the outer glass surface of the front, Reduced heater operation and manual work at start-up.

  And the most important effect is that a large amount of snow and rain on the front and rear window glass surfaces when driving a car is prevented from adhering by making the ultrasonic acceleration and vibration energy fine and bounce, and the high speed of the wiper It is possible to reduce wear damage due to operation and failure of the drive motor, and to ensure the driver's visibility by removing dirt on the glass surface.

  Ultrasonic ice melting and snow melting cables are not strong, but can be installed over a wide area and can be used for long distances. It is done.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  In FIG. 1, it is an apparatus which melts ice inside a water pipe frozen in winter or in a cold region by ultrasonic waves. First, an ultrasonic water pipe melting device body 1 is formed by integrally processing an upper arm 2 and a lower arm 3 formed of a stainless alloy or a hard resin together with a spring 7 like a scissors so that it can be grasped with a palm. To do.

  Then, in the upper arm 2, an electrode 9 is disposed on the ultrasonic transducer 4 to generate an ultrasonic wave, which is incorporated together with a horn 5 attached to strengthen the ultrasonic wave.

  Further, a water pipe tip tool 6 that is in direct contact with the water pipe is attached to the tip of the horn 5, and the acceleration of the ultrasonic wave generated from the ultrasonic vibrator 4 on the ice inside the water pipe swollen by the water pipe contact portion 8. And it conveys vibration energy and melts ice.

  Next, in FIGS. 2 and 3, the apparatus melts snow on the road surface 17 (especially an asphalt pavement) and ice-burned ice frozen in winter or in a cold region by ultrasonic waves.

  First, reference numeral 10 denotes an ultrasonic road ice melting and snow melting device main body, which is embedded almost at the center of the road surface 17 and fixed by a fixing nail 18 made of steel or hard resin. In this case, a titanium alloy, a stainless alloy, or a hard resin material is used for the center portion 16.

  The main body 10 is configured by arranging a horn 12 attached to an ultrasonic transducer 11 from the center to the four sides so as to be circular, and further attaching a road tip tool 13 to the tip (outer periphery) thereof. These are integrally formed into a circular shape by a protective body 14 such as a titanium alloy.

  Then, it is embedded in the center of the road, and ultrasonic waves are radiated horizontally and in all directions to travel through the asphalt, so that the above-mentioned energy frozen ice and snow can be melted on the road surface. Further, when it is desired to obtain acceleration and vibration energy, the above-mentioned integrated structure is stacked as several layers.

  Note that the filler 19 between the upper and lower protective bodies 14 and the ultrasonic transducer 11 is made of a soft resin or rubber.

  Next, in FIG. 4 and FIG. 5, the ultrasonic mat main body 20 for the passage surface has horns 22 attached to both surfaces (or one surface) of a small ultrasonic transducer 21 inside, and they are fixed to a fixing plate 23 (semi-rigid resin). Material). Further, a tip tool is attached to the tip of the horn to form one section, which are connected by a soft resin material 25 and formed into a laying mat shape.

  On the other hand, in FIGS. 6 and 7, freezing and snow accumulation on the outer glass surface 30 of the outer front window 31 of the automobile is melted by ultrasonic waves in winter and in cold regions, and it is finely bounced to prevent adhesion and remove (with a cleaning effect). In addition, it is possible to prevent and remove adhesion in the same manner as described above for snowfall and rain during running.

  First, reference numeral 26 denotes an ultrasonic automobile window ice melting and snow melting and cleaning device body, which includes an ultrasonic vibrator 27 and a horn 28 for strengthening the ultrasonic wave (attaching a tip tool 38 made of titanium alloy or stainless alloy as required). (Hereinafter abbreviated) is covered with the soft resin material 29 except for the portion in contact with the outer glass surface 30 and bonded with the soft adhesive 33 to be integrally molded.

  This is bonded and fixed directly to the outer glass surface 30 with a soft adhesive 33 at a lower portion where the elastic rubber 35 supporting the outer front window 31 is provided. However, this adhesion excludes the portion where the horn 28 and the outer glass surface 30 are in contact.

  This is so that the acceleration and vibration energy of the ultrasonic waves are directly transmitted to the surface of the outer glass surface 30, but it should be such that the outer glass surface 30 is not broken or adversely affected.

  In FIG. 8, as the ultrasonic ice melting and snow melting cable body 39, a soft resin material 41 is processed into a cable shape having a hollow portion 44, and at the same time, a small and thin circular ultrasonic transducer 40 having the hollow portion 44 is formed. , And arrange them at regular intervals.

  A horn 42 and a tip tool (titanium alloy or stainless alloy; hereinafter abbreviated) 43 are attached to the outer peripheral portion of the vibrator 40, and the electric wire 45 is passed through the hollow portion 44.

  The operation of the above configuration will be described below. In FIG. 1, a frozen water pipe is swallowed by a water pipe contact portion 8 of an ultrasonic water pipe melting apparatus body 1 that can be gripped with a palm like a scissors against a water pipe frozen in winter or in a cold region. The ultrasonic acceleration and vibration energy generated by the ultrasonic transducer 4 and strengthened by the horn 5 are directly transmitted from the tip tool 6 for water pipe to ice molecules inside the water pipe, thereby generating heat inside the pipe and melting the ice. Is.

  In addition, since the inside of the water pipe is not only in a completely frozen ice state, but also has tap water and a liquid part that is in the process of melting, melting due to the ultrasonic cavitation effect can be expected, thereby reducing the ice melting time.

  Next, in FIGS. 2 and 3, an ultrasonic road integrally formed in a circular shape by the tip tool 13 while arranging the ultrasonic vibrator 11 in four directions on the road surface 17 frozen in winter or in a cold region. The ultrasonic waves generated from the ice melting and snow melting device main body 10 are further strengthened by the horn 12 and the road tip tool 13 and radiated in the horizontal direction and in all directions.

  The main body 10 is embedded almost at the center of the road surface 17, and the acceleration and vibration energy of the ultrasonic waves radiated by the horn 12 and the road end tool 13 are passed through the solid asphalt and It melts ice and snow.

  In addition, since the water that has been melted and liquefied on the road surface 17 is also combined, melting due to the cavitation effect becomes stronger and the time can be shortened.

  In order to obtain a stronger ultrasonic acceleration and vibration energy, the ultrasonic transducer 11 and the horn 12 can be obtained by stacking them as a layer.

  4 and 5, the ultrasonic mat body 20 for the passage surface is laid in a doorway or a garden, so that ultrasonic waves can be generated from the portion where the horn 22 is attached to both surfaces (or one surface) of the internal ultrasonic transducer 21. Occurs and melts ice and snow immediately above the mat and the ground surface.

  On the other hand, in FIGS. 6 and 7, firstly, ultrasonic waves oscillated in a vertical direction from a circular ultrasonic transducer 27 smaller than the palm are attached so as to be in direct contact with the outer glass surface 30 of the outer front window 31 of the automobile. Frozen ice and hardened snow accumulated on the outer glass surface 30 through the horn 28 are prevented and removed by melting and refining, and the driver's visibility can be sufficiently secured by removing dirt. .

  Further, even when the automobile is running, it is possible to prevent and remove snow as well as snow and rain during rain as in the above case. However, since the ultrasonic acceleration and vibration energy may be transmitted only from the horn 28 to the outer glass surface 30 of the automobile window and perform an action such as melting or miniaturization, the ultrasonic vibration 27 and the protective body 29 are not affected. As the adhesive, a soft system that does not transmit ultrasonic waves is used.
