Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: Current rear-view mirrors for automobiles have a poor visibility and are dangerous to the driver because water droplets adhere to the mirror surfaces when driving in the rain. In particular, in the case of rainy weather at night, since the water droplets adhering to the mirror are reflected by the irradiation of the light from the following vehicle, the reality is that the mirror does not function. In addition, the danger is extremely high during long running on highways during heavy rain. Further, even in the case of other glass such as a windshield, the danger is great due to the influence of water drops adhering to it. Therefore, safety measures against these are required. SOLUTION: The present invention automatically senses water droplets or the like adhering to the surface of a mirror or the like in order to eliminate the risk of vehicle driving caused by the water droplets or the like adhering to the surface of a mirror or the like.
On the basis of the automatic detection, the high-pressure hot air or the high-temperature compression air, which constantly maintains a high rejection efficiency, can be automatically jetted onto the surface of the mirror or the like.

[Problems to be solved by the device]

 Of the 45 prior arts described in the related art and belonging to the relevant technical field, NO. 3, NO. 10, NO. 13, NO. 17, NO. 23, N. 34, NO. 37, NO. Reference numeral 42 denotes the removal of water droplets and the like from the mirror surface due to the inflow of air from the rear surface of the rear-view mirror during traveling. However, the important point actually required for other glass, such as automobile rearview mirrors and front glass, is not simply to be able to adhere and eliminate water droplets. In the action of eliminating such water droplets, it is possible to retain the basic elements (hereinafter referred to as the basic points) that automatically sense and operate without putting an excessive load on the driver even while driving. is necessary . In addition, it is important that the so-called removal efficiency is high so that water droplets, etc. can be immediately removed from the viewpoint of safe operation and can be immediately dealt with even at the time of freezing. Therefore, from this point of view, each of the inventions of the above-mentioned numbers is to inject air from the rear surface of the rear-view mirror and remove water drops and the like by the inflow air. Therefore, there is a drawback that the effect cannot be expected when the vehicle is stopped or running at low speed. Second, NO. 11, NO. 12, N 〇. 27, NO. 36, NO. No. 38, but it is the removal of water droplets, etc., by means of strip-shaped air jets, etc., and in consideration of heavy rain, the removal efficiency is diminished from the viewpoint of immediately removing adhering water droplets, etc. There are drawbacks. In addition, the basic points are lacking. No. 3 as the third. 45, NO. No. 25, this device is a mechanism for eliminating water droplets or the like due to air inflow from the tact or ventilation guide hole during traveling. Therefore, it has the same drawbacks as the first. The fourth is NO. 22, NO. 15, NO. No. 2 is the removal of water droplets by attaching a wiper such as moving to the mirror surface or rotating the mirror itself. However, in reality, when the wiper moves or the like, the wiper itself obstructs the driver's view of the mirror, which is dangerous. In addition, the rotation effect has the drawback that the mirror itself is not circular in all vehicle types, and the side rear image depicted on the mirror becomes unclear due to rotation.

As a fifth example, NO. 32, NO. Both are due to the introduction of air from a ventilation fan or the like in the passenger compartment or the introduction of warm air from an air duct. However, from the viewpoint that the introduction pressure of both is weak, the removal pressure of water droplets is weak, and if the engine itself does not reach a certain temperature even on the hot air surface, there is a drawback that hot air cannot be expected. Next, NO. 6 as the sixth. 43, NO. In the case of No. 7, the former is a mirror surface with a flexible film, and the latter is a method of spraying water-repellent treated water on the mirror surface together with water-repellent treatment. The former has the drawback that the water-repellent film on the mirror surface is washed off due to the characteristics of the mirror during heavy rain, and the latter has the same drawback, and the mirror surface freezes or becomes cloudy during cold weather. It is not appropriate from the viewpoint that a good visibility to the mirror is required promptly.

Next, as the seventh, NO 1, NO. 4, NO. 5, NO. 6, NO. 19, NO. 26 and NO. 28, NO. 29, NO. 30, NO. 33, NO. 35, NO. 41, NO. No. 18 is to remove water droplets and the like adhering to the mirror surface by injecting compression air onto the mirror surface. However, these devices lack the basic points and lack of measures for freezing the mirror surface in cold weather, that is, the so-called compression air cannot release the freezing of the mirror surface quickly. In addition, these have the drawback that only the rearview mirror is targeted, and no consideration is given to the entire vehicle body.

Eighth, NO. 20, NO. 31, NO. 39, NO. 44, NO. 21, further NO. 40, but NO. In addition to lacking the basic points, No. 20 has the drawback that no measures such as freezing of the mirror surface during cold weather have been taken. NO. In addition to lacking the basic points, the reference numeral 31 sucks the removed water droplets, so that the water droplets are mixed with the dust and the like. As a result, there is a drawback in that the vicinity of the air intake port of the air compression source is damaged by the accumulation of dust and the like. In addition, NO. In No. 39, in addition to the lack of basic points, the heater heat introduction by the nozzle is only through the side window. Considering the freezing / cloudiness of the mirror surface during cold weather or heavy rain, it is the rear-view mirror rather than the side window that requires higher compression air temperature. Therefore, it lacks appropriateness in this respect and has no specific heat source for the heater. Furthermore, NO. 44, NO. In No. 21, in addition to the lack of basic points, consideration for all of the vehicle body necessary for the driver, such as the back mirror and each glass, is lacking. Although the compressed air and the washer liquid are used in combination, the measures are not sufficient when the surface of the mirror freezes or becomes cloudy during cold weather or when it rains heavily. Next, NO. In No. 40, there is no consideration for the basic points and the overall field of view, and there is no concreteness as to the source of the warm air in terms of hot air blowout at the time of freezing.

[0007] As the ninth, NO. 8, NO. 9, NO. 16, NO. 24, but NO. 8 is a window wiping method in which the compressed air is sent to the wiper. It lacks consideration for the basic points and all of the car body, and there is no measure against freezing or clouding during cold weather. In addition, NO. No. 9 considers the vehicle as a whole, but lacks the basic points and has the drawback that the coating with the water-repellent agent is quickly washed away by rainwater during rain. In addition, measures against the surface freezing and clouding of mirrors and the like during cold weather are insufficient. Next, NO. 16, but lacks consideration for the basic points and the entire vehicle body. The cleaning liquid is sprayed, the compression air is sprayed, and the mirror surface is dried by heat rays.However, the spray of cleaning fluid is meaningless in the case of heavy rain, and the purpose of the defogger, which is a heat ray, is to remove fogging on the mirror surface. Has no immediate effect and is virtually ineffective. Furthermore, NO. No. 24, pressurized hot air is overheated in the overheat pipe unit that uses the exhaust heat of the exhaust pipe. The overheat is due to the heat conduction of the overheat pipe band, and the temperature adjustment is also done by the temperature adjustment bolt. It is an adjustment based on the rotation of. Removal of water droplets and the like from the mirror and each glass, what is most required for so-called automatic driving is the basic points and the improvement of the elimination efficiency. In this respect, there is a lack of basic points, and there is the burden of having to go to the exhaust pipe for each temperature adjustment. Regarding this temperature, from the perspective of improving the efficiency of elimination of adhering water droplets etc. immediately, the effect of eliminating water droplets etc. based on the pressure of the compression air is enhanced, so that water droplets etc. can be promptly removed by so-called high heat. The function must be enhanced by reducing the pressure load on the compression air by miniaturization or evaporation. Therefore, the temperature of the highly heated compression air must be kept above a certain level due to damage to the ejection pipe and the effect on the human body, etc. The following temperatures must also be prevented. At this point, there is no specificity as to the temperature of the pressurized hot air injected, which is a serious drawback from the viewpoint of rejection efficiency. Furthermore, if added, this is an unsuitable drawback for passenger cars that do not have a compressor.

The present invention has been made in view of the above problems of the prior art, and an object thereof is a driving accident due to adhesion of water droplets or the like to a rearview mirror or the like during night rain or the like. In order to prevent this, an object of the present invention is to provide a device for eliminating water droplets adhering to automobile rearview mirrors and the like, which is equipped with the above-mentioned basic points and conditions for enhancing the efficiency of elimination.

Further, in the case of the compressor 7 and the heater pipe 31, it is installed inside the delivery pipe 8 in the immediate vicinity of the delivery pipe 8 from the heater pipe 31 to the rearview mirror A and the like. The wiring from the installed thermistor 30 passes through the delivery pipe 8 to the outside and is connected to the wiring from the electronic circuit box 6. The changeover switch box 35 is provided with five switch buttons, and the leftmost switch is a double-push current open / close switch corresponding to all of the rearview mirror A and the like. The switches from the second to the fifth are the switches corresponding to the rear-view mirror A, the door window B, the front window C, and the rear window D, which are pressed twice. The wiring is connected to each switch, and the wiring on the opposite side of the changeover switch box 35 is connected to the engine switch 33.

Next, the heater tube 31 (not shown) will be described. The heater tube 31 is used in the case of an automobile in which the high-pressure hot air blower 5 is not used, that is, a vehicle equipped with the compressor 7, and the high-pressure hot air blower 5 is structurally modified. In appearance, the portion corresponding to the connecting portion of the wrapper pipe 11 of the high-pressure hot air blower 5 is reduced to be connected to the delivery pipe 8 of high-pressure air from the compressor 7, and the other end is the high-pressure hot air blower. It is the same as 5. In the internal structure, wire nets 16 are provided at both ends in the same manner as in the case of the high-pressure hot air blower 5, and the ends of the spiral nichrome wire 15 arranged between them are connected to the respective wire nets 16. The connection position of the heater pipe 31 is connected to the delivery pipe 8 between the compressor 7 and the delivery pipe 8 point in which the thermistor 30 is installed.

FIG. 2 is an overall connection diagram. First, the high-pressure hot air blower 5 is installed in the engine part, and the delivery pipe 8 is connected to it. An electronic circuit box 6 is further installed in the so-called engine part in the immediate vicinity of the delivery pipe 8 and is installed in the delivery pipe 8 and a thermistor 30 (not shown) is located between them. Further, the delivery pipe 8 is routed under the so-called underfloor, and is branched for connection to a small delivery pipe 32 (not shown) connected to the left and right rearview mirrors A, door windows B, and front windows C. Has been. The branched delivery pipe 8 is connected to the small delivery pipe 32 arranged from these rearview mirrors A, etc., and the undelivered delivery pipe 8 is extended as it is to the underfloor portion of the window A, and the rear window D is provided. It is connected to the connected small delivery pipe 32 (not shown). Next, in the case of an automobile that does not use the high-pressure hot air blower 5 such as a large-sized bus or truck equipped with a compressor 7, a heater tube 31 (not shown) is used instead of the high-pressure hot air blower 5.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. First, FIG. 1 is a partial shortening principle of automatic detection of water droplets 1 or the like that adhere, and is a diagram that serves as the origin when automatically detecting water droplets 1 or the like that adhere to the rearview mirror A or the like. . The current-carrying band 2 is adhered to the non-current-carrying product 3 which does not allow current flow so as to be buried in parallel with each other at a slight interval so that about half of each of them is embedded, and one end of each is bonded. Is connected to the wire of the conductive cord 4 and the other end is not connected to anything. When the engine switch 33 is turned on, a weak current having no influence on the human body flows into the conductive cord 4 via the battery power source 34 and the electronic circuit box 6. The flowing weak current passes through the connecting portion between the conductive band 2 and the conductive cord 4 and flows into each conductive band 2. Since the conducting band 2 is adhered to the non-conducting article 3 in parallel at a slight distance, in this state, one conducting band 2 flows and a weak current does not flow to the other conducting band 2. However, in this state, when a so-called water drop 1 such as rain or water containing water drops is attached between the conduction band 2 and the other conduction band 2, the weak current flowing in the conduction band 2 is After passing through the water droplets 1 etc., it flows to the other conductive band 2. The inside of the electronic circuit box 6 senses the action of the weak current that has flown, and automatically detects water droplets or the like 1 attached to the so-called conductive band 2. Adhesion of each conductive band 2 on the rearview mirror A of the present invention is for automatic detection of adhesion of water droplets 1 by applying this principle.

Next, the strong-pressure hot air blower 5 shown in FIGS. 3 and 4 will be described. In the high-pressure hot air blower 5, electric current automatically flows through the wiring connected from inside the electronic circuit box 6 that automatically detects the attachment of the water droplets 1 described above, and the motor 9 installed inside rotates. Along with this, the rotary fan 13 rotates. Due to the rotating action, air is sucked from the trumpet tube 11 which is wide open to the outside. The sucked air is installed between the trumpet pipe 11 and the motor 9 and the rotating fan 13, passes through the filter 14 and is sucked into the inside, so that dust and dirt are removed and become good air. Inhaled inside. The air sucked inside further passes between the motor support frame 10 and the motor support frame 10, and further flows to the delivery pipe 8 via the wire net 16, the nichrome wire 15, and the wire net 16. At the same time as the motor 9 rotates, a current flows through the wiring from the inside of the electronic circuit box 6 to the nichrome wire 15 installed on the way, so that the nichrome wire 15 generates heat. Therefore, the air sucked in when passing through these is hot air, that is, hot air. Since this hot air is reduced in size by the high-pressure hot air blower main body 12 in front of the delivery pipe 8 connection portion in accordance with the delivery pipe 8, the hot air flowing into the delivery pipe 8 has a strong pressure due to the reduction, so-called semi-high pressure. Change into hot air. In the high-pressure hot air fan 5, three single units of this structure are combined and formed integrally, so that the semi-high-pressure hot air flowing into the delivery pipe 8 is combined and flows in. That is, the semi-high pressure hot air changes to high pressure hot air. The trumpet tube 11 is of a plug-in type in the main body 12 of the high-pressure hot air blower in order to facilitate cleaning of the filter 14, and a magnet 18 is adhered to the inner diameter side of the connecting portion in order to facilitate the connection. Further, a metal 19 is adhered to the strong pressure hot air blower main body 12 side corresponding to the magnet 18. Since the high-pressure hot air fan 5 is attached to an appropriate place on the engine part, the fixing foot 17 for attachment is attached to an appropriate place on the main body 12 of the high-pressure hot air blower. The packing 20 is for preventing the leakage of high pressure hot air.

5 to 8 will be described. FIG. 5 is a partially shortened cross-sectional view of the rear-view mirror A as seen from the side, and FIG. 6 is a partially cut-away front view of the rear-view mirror A when the internal hollow holes of the jetting body 22 such as high-pressure hot air are not displayed. Is. Weak flow from the conductive band 2 to the other conductive band 2 due to water droplets 1 adhering to the two conductive bands 2 bonded to the mirror holding frame 21 corresponding to the non-conductive product 3 in FIG. The electric current flows from the conductive cord 4 into the electronic circuit box 6. Therefore, the inside of the electronic recessed path box 6 which has sensed the attachment of water droplets 1 to the conduction band 2 with a weak current causes the operation start current to flow through the wiring to the high-pressure hot air blower 5 at the same time as it is sensed. Therefore, when water droplets 1 or the like adhere between the conductive bands 2, the high-pressure hot air blower 5 starts operating almost at the same time. The high-pressure hot air generated by the start of the operation passes through the delivery pipe 8, the mirror support inner hole 29 passes through the small delivery pipe 32 protected by the introduction pipe 24, the high-pressure hot air blowout body 22, and the mirror 28 from the ejection port. Emit all over the surface. The pressure of the strong hot air increases at the time of passing from the delivery pipe 8 to the small delivery pipe 32 having a smaller inner diameter, and the jet port to the surface of the mirror 28 also becomes smaller so that the pressure does not decrease. ing. Furthermore, the temperature of the hot compressed air makes it easy to miniaturize or evaporate the water droplets 1 adhering to the surface of the mirror 28 so that the ability to remove the water droplets 1 by the pressure of the hot compressed air is kept constant. In addition, the temperature is maintained within a fixed frame by the cooperation of the thermistor 30 and the electronic circuit box 6 installed in the delivery pipe 8. That is, since the temperature of the intake air from the trumpet pipe 11 of the high-pressure hot air fan 5 differs between summer and winter, the intake air temperature in the so-called summer and winter should be adjusted so that the temperature of the high-pressure hot air ejected from the ejection port does not change accordingly. It is possible to inject high-pressure hot air with a temperature within a fixed frame regardless of the temperature. The outside temperature is high in summer and low in winter. Therefore, the high-pressure hot air temperature to the human body is felt as an extremely high temperature in summer and as a low temperature in winter. This applies not only to the feeling of the human body, but also to the temperature of the surface of the mirror 28 due to contact with outside air or the like. Therefore, in consideration of this point, the hot air temperature is lowered a little in summer and the hot air temperature rises a little in winter in order to match the so-called standard hot air temperature. Therefore, the temperature of the high-pressure hot air is a temperature that satisfies certain conditions regardless of summer or winter. That is, a high degree of exclusion efficiency is always maintained. The maintenance of the exclusion efficiency is the same for the door window B, the front window C, and the rear window D. Further, the same is true when the compressor 7 and the heater tube 31 are used instead of the strong pressure hot air blower 5. 7 and 8, FIG. 7 is a side sectional view of the upper side of the front window C and the rear window D. Due to the fact that the frame itself is the jetting body 22 such as high-pressure hot air, the body 23, the jetting body 22 such as high-pressure hot air, and the glass 25 are integrally fixed. Therefore, the left side is inside the vehicle and the right side is outside. Therefore, as described above, due to the fact that the jet 22 of the high-pressure hot air is a frame, the high-pressure hot air introduced by the water droplets 1 adhering between the conductive bands 2 adhered to the outer frame surface is introduced. Is ejected from the ejection port onto the surface of the glass 25. FIG. 8 is a partially cutaway front view of the left window when the front window C and the rear window D are viewed from the outside. Therefore, the left side becomes the body 23 and the right side becomes the glass 25. In this case as well, since it is the same as the above, the strong hot air introduced is ejected from the ejection port to the right side glass 25 surface by sensing the attachment of water droplets 1 to the conduction band 2. In this case, the conduction band 2 has the same pole at the first and third positions from the left and the same pole at the second and fourth positions from the left. Therefore, there is no problem even if water droplets 1 adhere to the second and third areas. Further, even if the water droplets 1 to 4 are attached to the entire surface for some reason, there is no problem because a safety measure for preventing danger is provided in the electronic circuit box 6.

FIG. 9 is an operation system diagram of the present invention. By turning on the engine switch 33, a current flows to the electronic circuit box 6, the changeover switch box 35, the rearview mirror A, and the conduction band 2 of each window. In this case, the five switch buttons of the changeover switch box 35 are all pressed twice. The 1st left side switch is all the current open / close switches, and pushes the switch once when sending only strong pressure air instead of strong pressure hot air to the rearview mirror A and all others. Therefore, the one-time pressing is used only when dust and the like adhering to the surface of the mirror 28 or the like is removed. In this case, due to the action in the electronic circuit box 6, the others except for the heat generation operation of the nichrome wire 15 in the high-pressure hot air blower 5 are activated. Next, in the case of so-called automatic detection of jetting of high-pressure hot air, by pressing the switch one more time (two times in total), a weak current flows through the bonded conducting band 2. Therefore, when the water droplets 1 and the like adhere to the gaps between the conductive belts 2 during driving and running in this state, the hot compressed air blows out. So-called water droplets, etc. 1 are automatically detected and strong hot air blows out. In this case, the switch button is lit to show the strong hot air blowing action, and the switch button is extinguished after maintaining the lighting for a certain period of time, and then the operation returns to the beginning. If it rains during driving when the lights are off, pressing the switch two more times causes strong hot air to blow out again for a certain period of time. Of course, if the running is stopped and the engine switch 33 is turned off, the switch returns to the beginning and the jetting of the hot compressed air is also stopped. Due to the function of automatically detecting the attachment of water droplets 1 etc., this strong hot air blowing action causes so-called water to adhere between the conductive bands 2 even when the surface of the windshield etc. freezes at the start of operation in cold weather. Therefore, the above method has a great advantage that the surface freezing can be immediately removed. Therefore, there is no need to use engine rising heat or hot water or water to defrost the surface. The generation of the high-pressure hot air in this case is due to the cooperative action of the inside of the electronic circuit box 6, the thermistor 30, and the high-pressure hot air blower 5. Next, when only one of the rear-view mirrors A and the like is used, for example, when injecting only the rear-view mirror A with the strong pressure air or the strong pressure hot air, the second rear side from the left is the same as the above. Press the mirror A switch once or twice. When pressed once, strong pressure air is jetted onto the surface of the mirror 28, and when pressed twice, strong pressure hot air is automatically jetted when attachment of water droplets 1 is automatically detected. Since the switch button lighting and extinguishing in this case are the same as above, when continuing the high-pressure hot air injection, the switch button is pressed twice again as described above. Further, when not only the rearview mirror A but also other things are operated at the same time, for example, when the strong wind or the strong hot air is sprayed on the glass 25 of the rearview mirror A and the door window B, the left rear mirror A switch is followed by the left switch. Press the third door window B switch in the same way as above. When these switch buttons are pushed with the leftmost switch button pressed, the leftmost switch button automatically returns to the initial unpressed state due to the action in the electronic circuit box 6. Therefore, in this case, the high-pressure air or the high-pressure hot air is jetted onto the surface of the mirror 28 and the surface of the glass 25 of the door window B.

Next, referring to FIG. 9, in the case of using the heater pipe 31 without using the high-pressure hot air blower 5, that is, in the case of an automobile equipped with the compressor 7 such as a large-sized bus or truck, a heater is used instead of the high-pressure hot air blower 5. The tube 31 is used. In this case, as described above, the heater tube 31 has an internal structure in which a spiral nichrome wire 15 is stretched between two wire nets 16 installed at regular intervals. Therefore, the compressor 7 and the heater tube 31 and the thermistor 30 are activated by the action of the activation start current in the electronic circuit box 6 that detects the attachment of the water droplet 1 to the conduction band 2. The compression air generated by the operation of the compressor 7 is connected, passes through the inside of the delivery pipe 8, and changes to high-temperature compression air when passing through the heater pipe 31. This high-temperature compression air is delivered by maintaining the temperature at a constant level by the action of the thermistor 30 installed inside the delivery pipe 8 near the delivery pipe 8 connected to the heater pipe 31, maintaining a so-called high degree of exclusion efficiency. It passes through the pipe 8 and finally ejects from each ejection port. In this case, the method of operating each switch button of the changeover switch box 35 regarding the compression air and the high temperature compression air and the lighting and extinguishing are the same as above.

[Effect of device]

 Since the present invention is as described above, it has the following effects.

According to the first aspect, water drops and the like adhering to the rearview mirror and the like can be automatically sensed by the installation of the conductive band and the associated action of the changeover switch box and the electronic circuit box and the like accompanying it. Therefore, from the viewpoint of automatically removing adhered water droplets and the like, it does not place an unnecessary burden on the driver even while traveling, and is always the best condition for safe driving.

[0043] According to claim 2, the action of the high-pressure hot air by the high-pressure hot air blower or the action of the high-temperature compression air by the heater tube and the compressor, so-called injection pressure, is an auxiliary pressure based on the relationship between the delivery pipe, the small delivery pipe, the ejection port, and the like. From the increase, it is extremely high pressure. Therefore, it is not necessary to use a cleaning liquid, etc., because the action of removing adhered water drops is extremely high. Further, in terms of temperature, the temperature is extremely high, and therefore the removal ability is highly enhanced by the auxiliary action of micronizing or vaporizing the adhered water droplets. Therefore, it exerts an excellent ability to remove adhering water droplets during heavy rainfall.

In the third aspect of the invention, the temperature of the strong hot air or the high temperature compression air is always kept constant regardless of summer and winter by the cooperation of the thermistor, the changeover switch box, and the electronic circuit box. Therefore, a high degree of exclusion efficiency can be maintained at all times.

From the viewpoint of immediate effect on the injection of high-pressure hot air or high-temperature compression air, there is no need for so-called elapsed time, which is required for increasing engine heat, etc., as seen in the conventional technique. Therefore, even in the case of poor visibility due to freezing of the mirror surface at the start of operation in cold weather, there is no need to use hot air or hot water or water due to engine heat, etc. Can be released immediately.

Even in the case of rearward confirmation using the rear window, it is possible to easily confirm rearward safety as compared with the hot wire system from the viewpoint of immediate effect.

By operating various switch buttons of the changeover switch box, various injection eliminating actions are possible.
