Description

  The present invention relates to a method for cleaning a vehicle typified by an automobile, and more particularly to a car wash method capable of efficiently removing water droplets and the like adhering to the vehicle during cleaning, and a tool suitably used for the method.

  Cleaning of vehicles such as automobiles and trains is desirably performed regularly or irregularly from the viewpoint of not only improving the appearance by removing dirt and dust, but also maintaining the state of painting.

  Conventionally, as a method of washing an automobile, a car washing method using a gate-type large car wash machine and a car wash machine using a detergent for a car wash machine, or a car body wash manually by using a sponge, a car wash brush or the like. There is a hand-washing car wash method.

  At the same time, in recent years, when a car is washed with a large portal-type car wash machine, the car wash method by hand washing has been reviewed for reasons such as car wash damage on the painted surface of the vehicle.

  A spray-type manual car wash machine is also provided as a means for facilitating the car wash operation when performing this car wash by hand washing. As such a manual type car wash device, for example, there is a small coin type washer (also called a steam type car wash machine) installed in a car wash place, and this washer is equipped with high-pressure water or water from a nozzle of a hand-held spray gun. It is comprised so that the stain | pollution | contamination of a vehicle may be wash | cleaned by injecting warm water.

  In addition, the gasoline train (service station), etc., also has a service for carrying out car washing work separately from the refueling service. In particular, hand washing cars are increasing with the increase in users who care about car washing scratches. Yes. In addition, hand-washing car wash reflects the unique characteristics of each service station, and it has significant significance in differentiating from other service stations.

Prior to the present application, a manual type car washing device for performing hand washing and car washing has been proposed in, for example, Japanese Patent Application Laid-Open No. 2004-231555. In this document, a manual type car wash device including a cleaning tool that uses tap water and a drying tool that comfortably removes and dries the cleaned vehicle body by air blow is proposed. The car wash apparatus only solves the adverse effects based on the high pressure (about +200 to +600 kPa) of compressed air in the conventional coin-type washer.
JP 2004-231055 PR

  As mentioned above, in recent years, hand-washing cars have been reviewed, and the penetration rate is increasing. In this hand-washing car wash, the above-described small coin-type washer is widely used for removing dirt (washing work). No mechanical device is provided.

On the other hand, it is also true that wiping off water drops in a hand-washing car requires a lot of time and effort, which is a serious problem especially for businesses that use hand-washing as a service, such as gas stations. It has become.
Therefore, in the present invention, firstly, it is an object to provide a car washing method and a tool therefor that can greatly improve the wiping work itself and improve the efficiency of the car washing work.

Further, when the car is washed, water also enters the details of the vehicle, but the water that has entered such details cannot be removed by a simple wiping operation. And the water which entered this detail appears with the movement of a vehicle, and this reduces the politeness of the work in the whole car wash work.
Therefore, a second object of the present invention is to provide a car wash method and a tool therefor that can remove even water that has entered the details of such vehicles.

Furthermore, if it takes time for the wiping operation during car washing, the water droplets in the unwiped area will evaporate, leaving a trace. In particular, in the case of water droplets mixed with a wax component or the like, the trace becomes conspicuous.
Accordingly, a third object of the present invention is to provide a car wash method and a tool therefor that can quickly remove water droplets.

  In order to solve the above-described problems, the present invention provides a car washing method and a tool therefor that use hand-held compressed gas jetting means such as an air gun to blow off and remove water droplets at the time of car washing by the pressure of the gas jetted therefrom. It has been developed and the present invention has been completed.

  That is, the present invention includes a washing step for washing a vehicle using water or other liquid as a car washing method for solving the above problem, and a liquid removal step for removing liquid adhering to the vehicle after the washing step, In the liquid removing step, there is provided a car washing method characterized in that the liquid adhering to the vehicle is removed by ejecting the compressed gas from the hand-held compressed gas ejecting means.

  According to such a car wash method, the liquid such as water adhering to the vehicle in the washing step can be blown away by the compressed gas (compressed air or the like) released from the compressed gas ejecting means such as an air gun in the subsequent liquid removing step. Therefore, the conventional wiping work itself can be made unnecessary, and the efficiency of the car washing work can be improved.

  Further, by using a compressed gas such as compressed air, it is possible to blow away water that has entered the gaps of the vehicle that could not be removed by the previous wiping operation, and the completeness of the car washing operation can be greatly improved. In particular, since the compressed gas jetting means used in the present invention is hand-held, the shape of the vehicle and the removal status of water, etc. when compressed gas is applied are different from conventional car wash machines such as a gate type. While observing, the application status of compressed gas (adjustment of discharge pressure based on the discharge distance, application time, etc.) can be adjusted accordingly, so that car wash operations (especially water and other liquid removal operations) can be performed more accurately. It can be carried out.

  In addition, by blowing off the water droplets of the vehicle with the compressed gas, it is not necessary to rub the vehicle body with a rag to wipe off the water droplets. A high quality car wash operation can be provided.

  And since a water droplet can be removed rapidly only by spraying compressed gas with a compressed gas ejection means, it is possible to eliminate wiping residue and generation of evaporated water droplet traces.

  Furthermore, in a conventional wiping operation with a rag, etc., if the object to be washed is a vehicle with a high vehicle height such as a wagon car or RV car, a separate stepping pad is used to remove water adhering to the high place such as the roof. However, in the car wash method according to the present invention, it is possible to remove liquids such as water without the need for a step board or the like in the previous example if the height is such that compressed gas can be sprayed.

  The washing step includes all operations for spraying liquid onto the vehicle body during car washing. That is, it includes all steps of spraying various liquids such as a cleaning liquid containing a cleaning component such as a surfactant, a coating film protective liquid containing a coating film protective component such as a wax component, and water for removing these cleaning liquid and wax liquid. Therefore, the liquid used in this cleaning step is not limited to water, but includes a wide range of liquids containing a cleaning component / wax component. This washing step may be performed using a washing machine such as a steam car wash machine or a gate type car wash machine, or may be carried out manually using a car wash brush. However, in general, in a car wash using a large-sized car wash machine such as a gate-type car wash machine, since the vehicle is dried by air blow or the like, the liquid removal step performed in the present invention is performed in detail in the vehicle. The purpose is to reliably remove the liquid that has entered.

  The liquid removing step is performed to remove the liquid applied in the cleaning step from the vehicle body. In the car washing method according to the present invention, the above-mentioned operation and effect can be enjoyed by using a hand-held compressed gas ejection means in this liquid removal step. As such a hand-held compressed gas ejection means, it is necessary to have at least a weight and a shape that can be held and operated by the operator, and preferably a grip for improving the ease of operation by the operator. A part. Examples of such compressed gas ejection means include an air gun including an air duster gun, an air spray gun, etc. In addition, various instruments or tools capable of discharging compressed gas can be used.

  Such a compressed gas jetting means functions as a jet that blows away water droplets attached to the vehicle body by vigorously jetting a gas supplied from a compressed gas supply source such as a compressor, an air tank, or a cylinder for jetting gas, In addition to the one that ejects only gas, the one in which a wax component (a component that expresses at least one of the effect of glazing and the effect of protecting the coating film) is mixed into the gas may be ejected. .

  In the liquid removal step in the car wash method, the compressed gas is ejected in a fan shape or a belt shape in the ejection direction, and the compressed gas is ejected with a uniform discharge pressure in the length direction of the ejection cross section. It is desirable to remove the liquid adhering to the vehicle while moving the compressed gas ejection means using

  Using hand-held compressed gas jetting means that can jet compressed gas evenly in the length direction of the jet cross-section (cross-sectional shape perpendicular to the jet direction), water droplets remain in the area where the discharge pressure is weak In addition, by using such compressed gas jetting means, even when the water droplets are blown away while moving the compressed gas jetting means, the water drops do not remain in a streak shape. In addition, when using compressed gas ejection means that cannot eject compressed gas evenly, water droplets will naturally remain in the form of streaks. It is also possible to cope by sucking with a water absorbent.

  Furthermore, the compressed gas ejection means in which water droplets do not remain in a streak shape during use can be performed by adjusting the ejection cross-sectional shape of the compressed air ejected from each ejection outlet and the arrangement of each ejection outlet. For example, the water droplets moved by the compressed air ejected from any of the ejection ports can be further blown away by the compressed air ejected from the other ejection ports.

  And this invention is a nozzle attachment of the compressed gas ejection means attached to the discharge port of compressed gas in the hand-held compressed gas ejection means as an instrument thru | or tool for solving the above-mentioned subject, The compressed gas ejection And a long body portion extending from the attachment portion. The body portion has a plurality of compressed gas jets arranged in the length direction. Provided is a nozzle attachment for a compressed gas jetting means.

  Such an attachment is attached to a compressed gas discharge port of a compressed gas ejection means such as an air gun including the above-described air duster gun, air spray gun, etc., and the body portion is formed in a long shape and its length. A plurality of compressed gas jets arranged in a direction are provided. As a result, a gas such as compressed air supplied to the compressed gas ejection means can be ejected over a wide range over the length direction of the body portion. Therefore, for example, when used to remove water droplets during car washing, a wide range of water droplets can be obtained by moving the attachment in a direction crossing the length direction of the body portion while keeping the attachment substantially parallel to the vehicle body. Can be efficiently blown away and removed.

  It is desirable that the length of the body part is appropriately adjusted in relation to the purpose of use. For example, when used for blowing off water droplets at the time of car washing, it is desirable that it is formed to be about 20 to 80 cm, particularly about 30 to 70 cm in consideration of the application range and operability of compressed air.

  In particular, in the case of an attachment in which the discharge pressure of the gas jetted from the plurality of compressed gas jet nozzles is formed substantially uniformly in the arrangement direction of the jet outlets at a point 5 cm or more away from the jet nozzle, In such a water droplet removal application, it is possible to eliminate the possibility that water droplets remain in a region where the discharge pressure is low. Such an attachment adjusts, for example, the shape, size, orientation, and arrangement (including the interval) of the compressed gas ejection port, or adjusts the supply pressure of the compressed gas supplied to the attachment to a predetermined value. Etc.

  Furthermore, in order to solve the above-mentioned problems, the present invention provides a nozzle attachment for compressed gas ejection means formed in a shape different from that of the attachment.

  That is, it is an attachment for a nozzle of a compressed gas ejection means that is attached to a compressed gas discharge port in a hand-held compressed gas ejection means, and an attachment portion that is attached to the discharge port of the compressed gas ejection means, and is integrated with this attachment portion. A compressed gas jet port is formed in the body portion, and the jet shape of the compressed gas jetted from the compressed gas jet port is a fan shape in the jet direction, and It is the attachment for nozzles of the compressed gas ejecting means having a uniform discharge pressure in the length direction of the discharge cross-sectional shape.

  This attachment is also attached to a compressed gas discharge port in a compressed gas ejection means such as an air gun including an air duster gun, an air spray gun, etc., in the same manner as the attachment provided with a plurality of ejection openings in the long body portion. However, it is characterized in that the compressed gas is discharged with a uniform discharge pressure in the longitudinal direction of the ejection cross section, particularly in the ejection direction. By spreading the compressed gas in a fan shape and ejecting it, a wide range of water droplets can be blown out, and the direction of water droplet blowing out can be easily controlled. In this regard, if it is emitted in a conical shape, it becomes difficult to control the flight direction of water droplets. In particular, since the control of the direction in which the water droplets are blown off is important in the liquid removal operation in the car wash operation, this attachment is suitable for use in the car wash operation. The discharge angle (inner angle) of the compressed gas in such an attachment should be adjusted as appropriate depending on the distance between the jet port and the application section for blowing the gas, but is generally 20 to 150 °, particularly 45 to 120 °. It is desirable. In addition, it is desirable that the compressed air discharge angle be formed so as to be appropriately adjusted.

  In this nozzle attachment, the body portion can be formed in a long shape, and one compressed gas ejection port for expanding and ejecting the compressed gas into a fan shape can be formed near the tip of the side surface of the body. This makes it possible to easily equalize the discharge pressure in the ejection cross section, and even when compressed air needs to be widely blown to an area away from the operator's hand, such as a car wash operation. The work can be easily performed.

  Further, in the present invention, it is a hand-held compressed gas ejecting means for ejecting compressed gas supplied from a pressurized gas supply source, wherein the nozzle attachment according to the present invention is attached, or the nozzle attachment. Provides a hand-held compressed gas jetting means provided integrally with each other to solve the above-mentioned problems.

  This compressed gas jetting means may be one that attaches the nozzle attachment afterwards, or one that is previously integrated with the nozzle attachment.

  The nozzle attachment and the compressed gas jetting means according to the present invention can be suitably used for removing water droplets adhering to the vehicle body (ie, the liquid removing step) particularly during car washing, but for other uses. Can of course also be used. For example, it can be used for the purpose of removing water droplets and other liquids attached to a wide range, dust or other powders or particulates, regardless of the field of application.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a schematic view showing a work process of a car wash method according to the present embodiment, and FIG. 2 is a side view showing a compressed gas ejection means 10 to which a nozzle attachment 17 according to the first embodiment is attached. FIG. 4 is an exploded view of the nozzle attachment 17 according to the first embodiment, and FIG. 4 is a side view showing the compressed gas ejection means 10 to which the nozzle attachment 17 ′ according to the second embodiment is attached.

  First, a car wash method according to the present embodiment will be described with reference to FIG. In the car wash method according to the present embodiment, as shown in FIG. 1A, the vehicle C is washed using a steam car wash machine S, a car wash brush, or the like, as in normal hand washing (washing step). In this cleaning step, the vehicle C may be first wetted with water and then cleaned with a cleaning liquid, or the vehicle C may be cleaned with cleaning water mixed with the cleaning liquid. In any case, in this washing step, water, washing water or the like is applied to the vehicle C, and water droplets (or droplets) or the like adhere to the vehicle C as a whole. In FIG. 1A, the dirty part of the vehicle is shown in dark color.

  Then, after sufficiently cleaning the panel of the vehicle C, water droplets and the like adhering to the vehicle C are removed. In particular, in the present embodiment, as shown in FIG. 1B, compressed air supplied from an air compressor (not shown) is vigorously released from an air duster gun 11 serving as compressed gas ejection means 10, and vehicle C Water droplets adhering to the water are blown off to remove them (liquid removal step). In this liquid removal step, the region from which water droplets have been removed is shown in white in FIG.

  In this liquid removal step, it is desirable to perform gradually from a high place such as a roof in the vehicle C toward a low place such as a window and a bonnet, and water droplets adhering to the vehicle C are moved outside the vehicle C while moving with compressed air. It is desirable to do so. Further, the distance between the air duster gun 11 and the vehicle C can be adjusted as appropriate depending on the properties of the portion where the water droplets are attached, the amount of water droplets, and the like. For example, if the surface to which water droplets are attached is a vehicle body panel and the vehicle body panel exhibits a sufficient water repellent effect due to wax or the like, the distance between the air duster gun 11 and the vehicle C is kept long, It is desirable to efficiently remove water droplets attached to the water.

  In particular, in the present embodiment, since the liquid removal step uses the air duster gun 11 as the hand-held compressed gas ejection means 10, the application time of the compressed air is lengthened according to the water droplet removal status. Or the distance between the air duster gun 11 and the vehicle C can be adjusted to be simple and accurate in each work situation.

  In the car washing method according to this embodiment, if the washing step is washing with a highly foaming detergent, then if the liquid removal step is performed to remove the bubbles adhering to the vehicle C, the bubbles are washed away. Therefore, it is possible to greatly reduce the amount of water to be used and to contribute to environmental conservation.

Next, an embodiment of the compressed gas jetting means 10 suitable for use in the liquid removal step in the car wash method will be described.
[Embodiment 1]

  The compressed gas ejection means 10 shown in the present embodiment is configured by attaching a nozzle attachment 17 to the compressed air discharge port of the air duster gun 11 as shown in FIG.

  As the air duster gun 11 that can be used in this embodiment, a general-purpose one that is used for spraying compressed air in a maintenance shop of a vehicle C or a gas station can be used. In addition, the compressor and air tank that supply compressed air to the air duster gun 11 can also be diverted from those that have been used in automobile maintenance shops and gas stations. Further, the air duster gun 11 and a line for guiding compressed air from a compressor or the like may be provided with means for averaging (or making constant) the supply amount and supply pressure of the compressed air supplied to the air duster gun 11.

  The nozzle attachment 17 used in the compressed gas ejection means 10 includes an attachment portion 12 attached to the discharge port of the air duster gun 11 and a body portion 13 formed in a long shape having a length of about 50 to 60 cm. The body portion 13 is formed with a plurality of jet ports 14 arranged along the length direction thereof. Compressed air supplied from a compressor or the like is guided from the discharge port of the air duster gun 11 to the internal space 15 of the nozzle attachment 17, and the compressed air guided to the internal space 15 is exhausted vigorously from each jet port 14. The

  And since this jet nozzle 14 exists over the length direction of the body part 13, as a whole, compressed air will jet out from this nozzle attachment 17 in the shape of a belt.

  In addition, the nozzle attachment 17 can be rotated in the axial direction with respect to the air duster gun 11 so that the compressed air can be directed in an appropriate direction when the air duster gun 11 is held. It is desirable to be installed in Thereby, in a state where the air duster gun 11 is gripped, the compressed air can be discharged in an arbitrary direction such as an upward direction, a lateral direction, or a downward direction of the nozzle attachment 17.

  In addition, the nozzle attachment 17 can be arbitrarily opened and closed at the tip in the length direction so that compressed air can be intensively blown against water droplets or the like remaining in a specific part. A spout 14 can also be provided. At that time, it is also possible to configure such that the tip outlet 14 and the outlet 14 arranged in the length direction can be opened selectively by mechanical action.

  The nozzle attachment 17 is formed such that the discharge pressure of the compressed air ejected from the entire ejection port 14 is uniform in the length direction of the ejection cross section. If the discharge pressure increases or decreases in the length direction of the ejection cross section, water droplets accumulate in the weak pressure area.As a result, when the compressed gas ejection means 10 is moved along the vehicle C, This is to solve the problem of remaining in a streak shape.

  That is, in the compressed gas ejection means 10 shown in this embodiment, compressed air is ejected from the entire nozzle attachment 17 in a generally belt-like manner, so that the width direction ( That is, the discharge pressures are formed so as to be approximately equal in the length direction of the nozzle attachment 17. However, in this width direction, the difference in discharge pressure to the extent that water droplets do not concentrate is within the scope of the present embodiment. In addition, the discharge pressure of compressed air is naturally the highest in the projection region of the jet outlet 14 and gradually decreases with increasing distance from the projection area. However, in this embodiment, the range where the uniform discharge pressure is required is at least the jet pressure. This is a range including the projection range of the outlet 14. In other words, the discharge pressure may naturally be lower than that in a region outside the region where the jet port 14 is projected onto the vehicle body panel.

  In order to make the discharge pressure of the compressed air uniform in the width direction (the length direction of the body portion 13), the shape, size, arrangement interval, orientation, etc. of the jet port 14 can be appropriately set, and the discharge port A mesh such as a metal mesh can be installed on the screen. An example is shown based on FIG.

  The nozzle attachment 17 shown in FIG. 3 forms a first attachment 16a having a shape obtained by dividing the nozzle attachment 17 to be manufactured in a direction along the length direction, and the nozzle attachment 17 in combination with the first division. A screw hole 18 is formed in each of the divided members 16a and 16b. However, the screw hole 18 may be omitted when the divided members 16a and 16b are bonded to each other with an adhesive or fused.

  And each divided body 16a, b is present at the center when both are combined, and when each divided body 16a, b is combined with a recess 15 'for forming the internal space 15 that becomes a passage for compressed air Grooves 14a and 14b are formed so as to cross each other. The grooves 14a and b function as the jet ports 14 for jetting compressed air when the two divided bodies 16a and b are combined. Note that the shape, size, direction, interval, and the like of the ejection port 14 are not limited to the mode illustrated in FIG. 3 and can be variously set.

  Further, by adjusting the cross-sectional shape and arrangement of the compressed air ejected from the nozzle attachment 17, the compressed gas ejecting means 10 that does not leave water droplets in a streak shape is realized. That is, when water droplets are blown off while moving the compressed gas jetting means 10, the water droplets remain in a streak shape because the water droplets move and gather due to the compressed air ejected from one of the jet ports 14. However, the compressed gas jetting means 10 that eliminates the residual water droplets can also be realized by blowing off the water droplets that have moved and accumulated with compressed air jetted from another jet port 14. Furthermore, when compressed air is blown, the movement of the water droplets in the radial direction is prevented, and the remaining of the water droplets can also be prevented by blowing the compressed air so as to move all the water droplets in the linear direction.

  Therefore, in the present embodiment, it is desirable to control the movement of the water droplets as described above by equalizing the discharge pressure or adjusting the shape and arrangement of the ejection port 14.

The nozzle attachment 17 may be tubular, and may be linear or curved. Also, the radial cross-sectional shape of the nozzle attachment 17 can be formed in various shapes such as a circle, an ellipse, and a rectangle.
[Embodiment 2]

  FIG. 4 shows the compressed gas jetting means 10 configured by attaching the nozzle attachment 17 ′ according to the second embodiment to the air duster gun 11, and is used for the compressed gas jetting means 10 shown in this figure. The nozzle attachment 17 ′ has one spout 14 formed on the side surface in the distal direction of the body portion 13 formed in a long shape.

  The ejection port 14 is formed so as to eject compressed air in a fan shape in the ejection direction, and its inner angle is adjusted to about 90 °. As a result, the cross-sectional shape of the compressed air ejected from the ejection port 14 becomes long, the compressed air can be spread over a wide range, and the operation of removing water droplets can be performed quickly.

  The jet port 14 is formed on the side surface of the body portion 13 near the tip of the body portion 13 formed in a length of about 50 to 60 cm. This improves the operability when removing water droplets adhering to the vehicle C during car washing. That is, if the spout 14 is formed on the front end surface of the body portion 13, it is difficult to remove water droplets on a surface that is almost horizontal, such as a bonnet, but the side surface of the body portion 13 as shown in the present embodiment. If formed in this way, water droplets adhering to the horizontal plane can be easily removed by translating the body portion 13 along the vehicle body.

  In addition, by forming the spout 14 near the tip of the body part 13 that is formed in a long shape, even if it is a water droplet adhering to an area far from the operator, it can be easily done without requiring special measures. Can be removed.
