In particular, after washing a car contaminated with various factors, there is no car washing tool suitable for cleaning the water and foreign substances present on the outer surface of the car, so conventionally, a car wiper or a dry towel has been used manually.

However, the conventional manual removal of water and foreign substances takes a lot of time and requires high labor intensity, and at self-car washes, dry towels for personal possession or car window wipers provided for public use And when removing foreign substances, there is a concern that fine scratches may be left on the outer surface of the vehicle due to a rough towel or a window wiper with worn-out rubber. In particular, in winter, the longer the drying time, the longer the car's exterior was frozen in the form of thin ice after washing, and it was difficult to solve by manpower, so it faced the limit of car cleaning.

Accordingly, in Patent Document 1, a space is formed inside, an air inlet for supplying air to the space is formed on one side, and a concavity having a certain width and depth is formed on the lower surface to discharge the air supplied to the space to the outside. A unit body in which groove-shaped guide insertion slits are formed in the longitudinal direction; and an air outlet guide having a plurality of air outlets penetrating the upper and lower surfaces and inserted into the guide insertion slit to be coupled thereto.

However, as shown in FIG. 1, in the air injection unit 1 of Patent Document 1, the hand grip portion 1a corresponding to the handle and the unit body 1b through which air is injected are integrally formed in a straight line shape on the front .

So, when the operator holds the hand grip part 1a with his hand and places the unit body 1b on the outer surface of the car 5, the unit body ( There was a concern that 1b) would lean to one side.

The action and effect of the dry brush 100 for removing moisture and foreign matter from a car according to an embodiment of the present invention configured as described above will be described below.

As shown in FIGS. 2 to 12 and 23 , the dry brush 100 for removing moisture and foreign substances from a car according to the first embodiment of the present invention removes moisture present on the outer surface of the car 5 after washing the car. In order to do this, the air supply pipe (4d), which is flexible and flexible, of the air supply/vacuum suction device (4) installed in the car wash (2) is fixed to the fastening coupling part (34) of the handle (30) through a fastening coupling After combining, the currency is recognized by the currency recognition unit 3a of the main controller 3 (S10).

Here, the currency recognition unit 3a recognizes coins, bills, or cards.

However, if the amount of money is less than the basic rate set in the main controller 3, the currency recognition unit 3a requests more money (S11).

Then, as the currency recognition unit 3a recognizes the currency, the cleaning time equivalent to the currency is displayed through the cleaning time display unit 3c (S12), and at the same time, various cleaning modes can be selected from the cleaning mode selection unit 3b. state. (S13)

Then, after holding the handle 30 with the operator's hand, the dry brush 100 for removing car moisture and foreign substances is placed close to the outer surface of the car 5.

Then, the air movement pipe 10 of the dry gun brush 100 for removing car moisture and foreign substances is tilted to one side according to the thickness of the operator's hand holding the handle 30 .

Here, the inclined surface 14, which is the lower end of the air movement pipe 10, forms an almost horizontal state with the outer surface of the car 5, and the dry brush 100 for removing car moisture and foreign substances regardless of the thickness of the operator's hand Due to the inclined surface 14 of the air movement pipe 10, the handle 30 is naturally lifted upward, and the air movement pipe 10 maintains a constant distance from the outer surface of the vehicle 5.

That is, the brush rubber blade 40 located on the inclined surface 14 of the air movement pipe 10 closely and gently touches the outer surface of the vehicle 5 so that the distance between the inclined surface 14 and the outer surface of the vehicle 5 is almost uniform. The distance between the air moving pipe 10 and the outer surface of the vehicle 5 becomes almost uniform by centering to maintain the distance.

And, when the main cleaning mode (3b') is selected, the main air supply unit (4a) and the main vacuum suction unit (4b) of the air supply/vacuum suction device (4) are operated (S13), and at the same time, the cleaning time display unit (3c) The cleaning time displayed in is discounted at 1x speed by 1 per second. (S14)

Then, the air supplied from the main air supply unit 4a moves to the first air movement passage 11 of the air movement pipe 10 along the first connection passage 31 of the handle 30.

Here, since the circumference of the air moving tube 10 gradually decreases due to the inclined surface 14 as it goes from the opposite side where the handle 30 is formed to the side where the nozzle unit 21 is formed, the first air movement passage regardless of the distance. In (11), the air pressure is maintained uniformly, and the air pressure injected from the plurality of air injection holes 14b is also maintained uniformly regardless of the position.

So, as shown in FIG. 8 , when the dry brush 100 for removing moisture and foreign matter from a car is moved along the outer surface of the car 5, air is blown out of the car 5 through a plurality of air injection holes 14b. It is uniformly sprayed toward the outer surface, and uniform air pressure is delivered to water and foreign substances existing on the outer surface of the vehicle 5.

Here, since the plurality of air injection holes 14b are formed inclined at a predetermined angle θ toward the opposite direction of the brush rubber blade 40, the air is not perpendicular to the plurality of air injection holes 14b in advance. It is transmitted to the water and foreign substances while being sprayed on the outer surface of the vehicle 5 in a state inclined at a predetermined angle (θ).

In addition, since at least one first spiral groove 14b' formed in a spiral shape along the wall surface of the air injection hole 14b in the form of a concave groove wider than the depth is formed in the plurality of air injection holes 14b. , The air injected from the plurality of air injection holes 14b obtains rotational force while rotating by the first spiral groove 14b', and friction is minimized at the moment of passing through the wall surface of the air injection holes 14b.

Here, the air pressure is widely sprayed toward water and foreign substances in a vortex form from the plurality of air injection holes 14b while the air force is increased by the rotational force.

In addition, the air around the plurality of air injection holes 14b is sucked in while the pressure around the air injection holes 14b is lowered due to the air having high air pressure injected from the plurality of air injection holes 14b.

Here, since the curved first curved portion 15 is formed around the plurality of air injection holes 14b on the inclined surface 14 located at the lower end of the air movement pipe 10, the plurality of air injection holes 14b ) is easily sucked in.

That is, as the air around the plurality of air injection holes 14b is directed to the plurality of air injection holes 14b by the Coanda effect by the first curved portion 15, the air from the plurality of air injection holes 14b Belongs to the sprayed air.

In other words, the air injected from the plurality of air injection holes 14b further increases the air pressure and obtains a rotational thrust in the form of a vortex, so that the water and foreign matter are sprayed more widely toward the water and foreign matter, and the water and foreign matter cover a larger area and have a stronger receive air pressure.

In addition, compared to the end of the brush rubber blade 40 contacting the outer surface of the car 5 perpendicularly, the air discharged from the air injection hole 14b is inclined at a predetermined angle θ to the outer surface of the car 5. When sprayed, water molecules with surface tension in the form of water droplets are scraped and dug out by pneumatic pressure, and water and foreign substances are removed while being swept away from the outer surface of the vehicle 5.

In addition, since the fitting hole 14a and the fitting part 41 are formed in a shape similar to a circle, the brush rubber blade 40 is gently adhered to the outer surface of the car 5 and caught, so that the fitting part 41 is formed in a circle and It rotates at a small angle around the fitting hole 14a of a similar shape.

That is, the rubber blade 40 of the brush gently adheres to the outer surface of the vehicle 5 in the direction in which force is applied, so that it is less caught.

In addition, since the brush rubber blade 40 is made of a rubber material, it is flexibly bent while caught on the outer surface of the vehicle 5.

And, in the air moving pipe 10, the second connection passage 32 and the second air moving passage 12 are in a vacuum state by the main vacuum suction part 4b operated like the main air supply part 4a, and a number of The external air is uniformly sucked into the vacuum suction hole 14c of the vacuum suction hole 14c.

So, by moving the dry brush 100 for removing moisture and foreign matter from the car further along the outer surface of the car 5, finely remaining water and foreign matter on the outer surface of the car 5 are removed through a plurality of vacuum suction holes 14c. is absorbed and removed evenly.

That is, in moving the dry brush 100 for removing car moisture and foreign substances along the outer surface of the car 5, the large water that is considered to have a high load on the outer surface of the car 5 acts on the water molecules. For the purpose of weakening manpower, a large amount of water is removed in advance by using a brush rubber blade (40) with a brush function, and even after removal, small water and foreign substances remaining in the form of water droplets due to surface tension are air sprayed and vacuum suctioned It is removed by treating it twice or three times.

In addition, as shown in FIG. 9 , the dry brush 100 for removing moisture and foreign substances from the vehicle may be moved in the opposite direction to that of FIG. 8 to remove moisture and foreign substances present on the outer surface of the vehicle 5 .

That is, even after removing the water and foreign matter along the outer surface of the car 5 by wiping with the brush rubber blade 40, the water and foreign matter remaining in the form of water droplets due to surface tension are sucked through the plurality of vacuum suction holes 14c. While removing, the air pressure sprayed from the plurality of air injection holes 14b is pushed and removed with air having a high air pressure.

In addition, even if the dry brush 100 for removing car moisture and foreign substances is in close contact with the outer surface of the car 5 for a long time, since the brush rubber blade 40 made of soft rubber first touches the outer surface of the car 5, the car 5 ) is not scratched on the outer surface.

In addition, even if the dry brush 100 for removing car moisture and foreign substances is severely tilted to one side from the outer surface of the car 5, the rubber O-ring 50 fitted into the O-ring groove 20b of the closing part 20 ) touches the outer surface of the car 5 first, so that the outer surface of the car 5 is not scratched.

On the other hand, as shown in FIGS. 10 to 12 and 23, while removing moisture and foreign substances present in narrow gaps inside and outside of the vehicle 5, a dry brush 100 for removing moisture and foreign substances in the vehicle In the case of changing the purpose of use or opening all the doors of the car 5 for interior cleaning after cleaning the exterior of the car 5 and preparing for interior cleaning, the cleaning stop mode (3b'''') Select (S15)

In addition, the cleaning stop mode (3b'''') is selected when time is needed to move items that have not yet been cleaned inside the car 5, such as the trunk of the car 5. (S15)

Of course, when additional cleaning time is added by currency recognition to remove moisture and foreign substances from the outer surface of the car 5 and to remove moisture and foreign substances present in narrow gaps inside and outside the car 5 (S16), You can also select the cleaning stop mode (3b''''). (S15)

At this time, at the moment when the cleaning stop mode (3b'''') is selected, the cleaning time of the cleaning time display unit 3c is displayed slowly at 1/3 speed by 1/3 or 1/4 speed by 1/4 in units of 1 second. Counted. (S14)

Here, at the moment when the cleaning stop mode (3b'''') is selected, the main air supply part (4a) and the main vacuum suction part (4b) of the air supply/vacuum suction device (4) and the auxiliary air supply/vacuum suction part (4c) ) does not work.

In addition, when the dry brush 100 for removing moisture and foreign substances in the car is located in a narrow gap inside and outside the car 5, air is supplied from the cleaning mode selector 3b as shown in FIGS. 11 and 23 By selecting or changing the auxiliary cleaning mode (3b'') (S13) (S15), the auxiliary air supply/vacuum suction part (4c) is operated to pass through the third connection passage (33) of the handle (30) to the air moving pipe (10). Air is supplied to the third air passage 13 of the ) and the fourth air passage 20a of the closing part 20.

Then, air is injected from the nozzle hole 21a of the nozzle unit 21 toward the narrow gap between the inside and outside of the automobile 5, and the air pressure is transmitted to the water and foreign substances.

Here, since at least one second spiral groove 21a' formed in a spiral shape along the wall surface of the nozzle hole 21a in the form of a concave groove wider than the depth is formed in the nozzle hole 21a, the nozzle hole ( The air injected from 21a) is rotated by the second spiral groove 21a' to obtain rotational force, and friction is minimized when passing through the wall surface of the nozzle hole 21a.

Here, the air pressure is widely sprayed toward water and foreign substances in a vortex form from the nozzle hole 21a while the air force is increased by the rotational force.

In addition, the air around the nozzle hole 21a is sucked in while the pressure in the vicinity of the nozzle hole 21a is lowered due to the high-pressure air injected from the nozzle hole 21a.

Here, since the curved second curved portion 21b is formed around the nozzle hole 21a on the outer surface of the nozzle part 21, the air around the nozzle hole 21a is easily sucked in.

That is, as the air around the nozzle hole 21a is directed toward the nozzle hole 21a by the Coanda effect by the second curved portion 21b, it belongs to the air injected from the nozzle hole 21a.

In other words, the air injected from the nozzle hole 21a further increases the air pressure and obtains a rotational thrust in the form of a vortex, so that the water and foreign matter are sprayed more widely toward the water and foreign matter, and the water and foreign matter transmits a stronger air pressure to a wider area You will receive.

In addition, as shown in FIGS. 12 and 23, the auxiliary air supply/vacuum suction unit 4c may be operated by selecting or changing the vacuum suction auxiliary cleaning mode (3b''') (S13) (S15). .

Then, while the third connection passage 33 and the third and fourth air passages 13 and 20a are in a vacuum state by the air supply/suction part 4c, water and foreign matter are sucked into the nozzle hole 21a. Removed.

And, as shown in FIGS. 2 and 13 to 17 and 23, the dry brush 100 for removing moisture and foreign substances from a car according to the second embodiment of the present invention is brought close to the outer surface of the car 5. After positioning, air is supplied through the main air supply unit 4a.

That is, in the dry brush 100 for removing car moisture and foreign substances, air is injected from a plurality of air injection holes 14b formed on both sides of the brush rubber blade 40, respectively.

Then, since the plurality of air injection holes 14b are not perpendicular to the outer surface of the car 5 toward the opposite direction of the brush rubber blade 40 but inclined at a predetermined angle θ, a plurality of air injection holes In (14b), the air is sprayed to the outer surface of the vehicle 5 in an inclined state at a predetermined angle (θ) rather than vertically, and is transferred to water and foreign substances.

In addition, since at least one first spiral groove 14b' formed in a spiral shape along the wall surface of the air injection hole 14b in the form of a concave groove wider than the depth is formed in the plurality of air injection holes 14b. , The air injected from the plurality of air injection holes 14b obtains rotational force while rotating by the first spiral groove 14b', and friction is minimized at the moment of passing through the wall surface of the air injection holes 14b.

Here, the air pressure is widely sprayed toward water and foreign substances in a vortex form from the plurality of air injection holes 14b while the air force is increased by the rotational force.

In addition, the air around the plurality of air injection holes 14b is sucked in while the pressure around the air injection holes 14b is lowered due to the air having high air pressure injected from the plurality of air injection holes 14b.

Here, since the curved first curved portion 15 is formed around the plurality of air injection holes 14b on the inclined surface 14 located at the lower end of the air movement pipe 10, the plurality of air injection holes 14b ) is easily sucked in.
