Description

[Technical Field]

[0001] The present invention relates to a self-service car wash, and more particularly to a self-service car wash that provides an independent drying space and prevents scratches and recontamination of the vehicle caused by hose members used when draining water from the vehicle body and washing the interior of the vehicle. [Background technology]

[0002] Generally, various types of dirt and dust accumulate on the body, underside, and around the wheels of a car while the car is being driven or parked, and drivers wash their cars to prevent corrosion of the body caused by the dirt and to keep the exterior clean.

[0003] Self-service car washes are popular because they allow customers to choose the areas of their car that need washing, are inexpensive, easy to operate for people of all ages and genders, are open 24 hours a day, 365 days a year, and offer a wide range of vehicle-related services at low prices, such as minor vehicle maintenance and the sale of accessories, and the number of such facilities is gradually increasing.

[0004] Generally, a self-service car wash is divided into a booth structure with walls erected on both the left and right sides of a pillar at a predetermined distance apart, a vehicle body wash bay with a pair of rotating booms rotatably mounted on the cross beams of the booth structure, on which high-pressure water spray guns and foam spray guns are mounted, and a dry bay where vehicles that have had their bodies washed in the booth structure are moved to have the water wiped off the vehicle body or the interior washed.

[0005] The dry bay is equipped with an air gun that can blow away moisture from the vehicle body using high-pressure air and blow dust accumulated inside the vehicle to the outside, as well as a vacuum suction hose to suck up dust inside the vehicle.

[0006] The vacuum suction hose extends from a boom mounted on the top of the vacuum cleaner body, which is fixed to the ground and can rotate up and down and left and right, and the air gun is connected to one side of the vacuum cleaner body. The vacuum cleaner body is also installed between multiple dry bays so that it can be shared by multiple vehicles.

[0007] The vacuum suction hose and air gun are long enough to approach the vehicle from multiple directions and wash it thoroughly, but they hit the ground during use, splashing foreign objects on the ground and water from the vehicle onto the body. This can cause scratches on the inside and outside of the vehicle or recontamination if used with foreign objects or water remaining on the body.

[0008] Meanwhile, considering that the aforementioned self-service car washes are divided into a vehicle body washing space and a drying space, resulting in low space utilization efficiency, garage-style car washes that combine the vehicle body washing bay and the drying bay into one location have been developed recently.

[0009] Generally, in a garage-type car wash, a high-pressure water spray gun and a foam spray gun are connected to a rotating boom stand in the center of the space, and a vacuum suction hose and an air gun are installed eccentrically on one side of the space. As a result, existing garage-type car washes have problems such as inconvenient use of the vacuum suction hose and the air gun, and vehicles are recontaminated by foreign objects or water splashing onto the ground.

The fluid supply unit may include a plurality of fluid supply pipes extending toward the cylinder 522, a fluid storage tank for storing the fluid, a pump connected to the plurality of fluid supply pipes and the fluid storage tank for pumping the fluid supplied to the fluid supply pipes or the fluid in the fluid storage tank, and a control valve that opens and closes the fluid supply pipes to control the direction of fluid movement, and a control panel may be provided with buttons or levers that operate the pump and the control valve to adjust the expansion or contraction of the length of the slope adjustment member 521.

[0081] In the self-service car wash 502 according to the sixth embodiment of the present invention, when the hose members 51, 54, and 57 are in use, the slope adjustment members can be extended or contracted in length so that the rail 31 is horizontal or rotates at a downward incline toward the other side, and after the car wash is completed, the slope adjustment members can be extended in length so that the rail 31 is inclined downward toward one side so that the hose members 51, 54, and 57 can be guided to move toward one side of the rail 31.

[0082] On the other hand, FIGS. 9 and 10 show a self-service car wash 602 according to a seventh embodiment of the present invention.

[0083] The self-service car wash 602 according to the seventh embodiment of the present invention has a similar structure to the self-service car washes 2, 102, 202, 302, 402, and 502 according to the first to sixth embodiments of the present invention, except that the booth structure 5' is formed so that the entire vehicle can move, and further includes a plurality of rotating boom stands 630, a high-pressure water spray hose 640, a foam spray hose 650, and a boom stand alignment unit.

[0084] The self-service car wash 602 according to the seventh embodiment of the present invention is a garage-type car wash space 3' that combines a vehicle body space for washing the vehicle body and a dry space for cleaning the interior of the vehicle, and is equipped with a sink 611 on the left side of the control panel 12 and a trash can 613 on the right side.

[0085] That is, the booth structure 5' has a plurality of vertical bars 6 arranged in a row on both sides of the car wash space 3' so that the entire vehicle can enter inside, and further includes a second horizontal bar 620 extending from above the plurality of rail holding bars 11 in a direction perpendicular to the longitudinal direction of the rail holding bars 11 and spaced apart by the first horizontal bar 10.

[0086] Unlike self-service car washes in which the drying space and the space for washing the vehicle body are separated, the self-service car wash 602 according to the seventh embodiment of the present invention allows the vacuum suction hose 51, steam supply hose 54, air supply hose 57, high-pressure water spray hose 640, and foam spray hose 650 to be used without restrictions within a set period of time (e.g., 2 to 3 hours).

[0087] The plurality of rotating boom bases 630 are rotatably mounted on the second horizontal bar 620 so as to be spaced apart from one another with the plurality of rails 31 interposed therebetween.

[0088] A high-pressure water spray hose 640 extends from one of the rotating boom bases 630, and has attached to its end a high-pressure water spray gun 641 with a lever that can adjust the spray of high-pressure water.

[0089] A foam spray hose 650 extends from another rotating boom base 630 and has attached to its end a foam gun 651 with a lever that allows adjustment of foam spray.

[0090] The rotating boom base 630 comprises a fixed part 631 attached to the second horizontal bar 620, a rotating part 635 that rotates relative to the fixed part, and a boom base main body 638 that rotates up and down relative to the rotating part. The fixed part 631 comprises a fixed bracket 632 attached to the second horizontal bar 620, a rotation support shaft (not shown) extending downward from the center of the fixed bracket 632, and a flange 633 attached to the end of the rotation support shaft.

[0091] The rotation support shaft is formed with a through hole on the inside to form a passage for high-pressure water or foam to pass through, and a high-pressure water spray hose 640 or a foam spray hose 650 is rotatably connected to the end of the rotation support shaft.

[0092] The rotating section 635 includes a rotating cylindrical section 636 that is rotatably held on the outer surface of the rotation holding shaft, and a hinge frame 637 that is integrally formed on the outer surface of the rotating cylindrical section and to which a boom base main body 638 is hingedly connected. The flange 633 rotatably holds the rotating cylindrical section.

[0093] Referring to FIG. 10, the boom base alignment unit includes a plurality of inclined support plates 653 mounted between the lower surface of the second horizontal bar 620 and the fixed brackets 632 of the pair of rotating boom bases 630 .

[0094] The inclined support plate 653 is a tapered plate member that becomes thinner from one side to the other in the width direction.

[0095] One inclined support plate 653 is attached so that it becomes thicker as it moves from the center of the second horizontal bar 620 to one side in the longitudinal direction, and the other inclined support plate 653 is attached so that it becomes thicker as it moves from the center of the second horizontal bar 620 to the other side in the longitudinal direction.

[0096] As a result, the rotating boom base 630 is mounted so that the rotating shaft approaches the rail 31 in the width direction as it goes downward.

[0097] That is, when the user releases the pulling force of the rotating boom base 630 rotated toward the inside of the car wash space 3' by the user, the end of the rotating boom base 630 is automatically rotated in a direction in which it contacts the side walls 7 and 8.

[0098] On the other hand, the boom platform alignment unit may be provided with a torsion spring instead of the inclined support plate 653 .

[0099] Although not shown, a torsion spring is provided inside the rotating cylindrical portion 636, and one side is fixed to the flange 633 or the rotation support shaft, and the other side is fixed to the rotating cylindrical portion 636, and can provide a restoring force that allows the end of the rotating boom base 630, which has been rotated by the user toward the inside of the car wash space 3', to automatically rotate in a direction that contacts the side wall portions 7 and 8 when the user releases the pulling force.

[0100] Meanwhile, although not shown, the self-service car wash 602 according to the seventh embodiment of the present invention may also be provided with an electric vehicle charger 75. In this case, the sink 611 is provided adjacent to the trash can 613, and the electric vehicle charger 75 is provided to the left of the control panel 12.

[0101] Although the preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to these examples. It is clear that a person skilled in the art to which the present invention pertains can conceive of various modifications or alterations within the scope of the technical ideas set forth in the claims, and it is understood that these also naturally fall within the technical scope of the present invention.
