[0019] Hereinafter, an embodiment implementing a driving roller mounting structure of a moving carriage for a touchless automatic car wash machine according to the present invention will be described in detail with reference to the drawings.

[0020] FIGS. 1 to 3 are schematic drawings illustrating a no-touch automatic car wash machine related to the present invention.

[0021] Referring to FIGS. 1 to 3, the no-touch automatic car wash machine (10) related to the present invention includes a washing bay (20) provided for performing a vehicle washing operation and a drying bay (30) provided for performing a water removal operation on a vehicle after washing is completed.

[0022] Here, the washing bay (20) and the drying bay (30) are installed so that washing and water removal operations can be performed continuously, and a shutter (not shown) is installed between the washing bay (20) and the drying bay (30) to partition them.

[0023] Of course, a shutter (not shown) is installed at the entrance side of the washing bay (20) to control vehicles entering the washing bay (20), and a shutter (not shown) is installed at the exit side of the drying bay (30) to control vehicles exiting after drying.

[0024] Additionally, the no-touch automatic car wash machine (10) related to the present invention further includes a high-pressure spray device (40) installed in a washing bay (20) for spraying high-pressure water onto a vehicle, a cleaning liquid spray device (50) for spraying cleaning liquid onto a vehicle, and a drying device (60) installed in a drying bay (30) for discharging drying air onto a vehicle.

[0025] And the no-touch automatic car wash machine (10) related to the present invention further includes a first moving carriage (70) on which a cleaning liquid spraying device (50) is mounted together with a high-pressure spraying device (40), and a second moving carriage (80) on which a drying device (60) is mounted.

[0026] The high-pressure injection device (40) includes a rotary high-pressure injection pipe (42) and a motor (44) for the high-pressure injection device that rotates the rotary high-pressure injection pipe (42) along the outer edge of the vehicle.

[0027] The motor (44) for the high-pressure injection device is mounted so as to be built inside the first movable carriage (70), and the rotary high-pressure injection pipe (42) is mounted so as to be suspended on the lower side of the first movable carriage (70) so as to be exposed toward the vehicle.

[0028] A plurality of high-pressure water spray nozzles (46) are installed in the rotary high-pressure spray pipe (42), and the rotary high-pressure spray pipe (42) is bent so that high-pressure water can be sprayed to the upper surface of the vehicle and to any one side of the vehicle at the same time.

[0029] In other words, the rotary high-pressure spray pipe (42) and the motor (44) for the high-pressure spray device move along the first moving carriage (70) and spray high-pressure water onto the vehicle, and the motor (44) for the high-pressure spray device rotates the rotary high-pressure spray pipe (42) along the outer edge of the vehicle according to a signal from a control system (not shown), thereby spraying high-pressure water onto the top surface of the vehicle as well as both sides, the front, and the rear of the vehicle, so that the vehicle is cleaned.

[0030] Here, the connection relationship between the rotary high-pressure injection pipe (42) and the motor (44) for the high-pressure injection device and the introduction of cleaning water to the rotary high-pressure injection pipe (42) are known technologies, so a detailed explanation thereof is omitted.

[0031] The cleaning fluid injection device (50) includes a snow foam injection pipe (52) and a wax injection pipe (54) formed to extend along the width direction of the vehicle.

[0032] The snow foam injection pipe (52) and the wax injection pipe (54) are each mounted on the lower outer side of the first moving carriage (70) so as not to interfere with the rotary high-pressure injection pipe (42).

[0033] At this time, snow foam spray nozzles (54) that spray snow foam toward the vehicle are installed in the snow foam spray pipe (52), and wax spray nozzles (58) that spray wax toward the vehicle are installed in the wax spray pipe (56).

[0034] Preferably, both ends of the wax injection pipe (54) are bent downwardly so that the wax injected through the wax injection nozzles (58) can be injected toward both sides of the vehicle.

[0035] Here, the connection relationship between the snow foam injection pipe (52) and the wax injection pipe (54) and the first movable carriage (70) is not specifically limited in the present invention. In other words, any connection relationship is acceptable as long as the snow foam injection pipe (52) and the wax injection pipe (54) are mounted on the lower outer side of the first movable carriage (70).

[0036] In addition, since introducing snow foam and wax into the snow foam injection pipe (52) and the wax injection pipe (54), respectively, is a known technique, a detailed description thereof is omitted.

[0037] And the first moving carriage (70) is further equipped with a solenoid valve (not shown) that controls the flow of high-pressure water, snow foam, and wax, and since the solenoid valve and rotary high-pressure injection pipe (42), snow foam injection pipe (52) and wax injection pipe (54) are known technologies, a detailed description thereof is omitted.

[0038] The drying device (60) includes one or more top blowers (62) that blow high-pressure drying air toward the top side of the vehicle, a rotary side blower (64) provided as a single unit that blows high-pressure drying air toward any one side (side, front, rear) of the vehicle, and a motor (68) for the drying device that rotates the rotary side blower (64) along the outer edge of the vehicle.

[0039] The top blower (62) and the motor (68) for the drying device are mounted so as to be built inside the second moving carriage (80), and the rotary side blower (64) is mounted so as to be suspended on the lower side of the second moving carriage (80) so as to be exposed toward the vehicle side while connected to the motor (68) for the drying device.

[0040] At this time, the rotary side blower (64) is connected to the motor (68) for the drying device via the connecting arm (66), the rotary side blower (64) is connected to one end of the connecting arm (66) and the motor (68) for the drying device is connected to the other end of the connecting arm (66).

[0041] These top blowers (62), rotary side blowers (64), and motors (68) for drying devices move along the second moving carriage (80) and discharge high-pressure drying air onto the vehicle, and the motors (68) for drying devices rotate along the outer edge of the vehicle so that the discharge port of the rotary side blower (64) is directed toward the vehicle according to a signal from a control system (not shown), thereby discharge high-pressure drying air onto the top surface of the vehicle as well as both sides, the front, and the rear of the vehicle, and the moisture on the vehicle is removed.

[0042] Here, since it is a known technology that the top blower (62) and the rotary side blower (66) discharge high-pressure drying air, and that the rotary side blower (64) and the motor (68) for the drying device are connected via the connecting arm (66), a detailed description thereof is omitted.

[0043] And the drying device (60) further includes a balance weight (90) that balances the rotational movement of the rotary side blower (66) and reduces vibration to increase stability.

[0044] The balance weight (90) is integrally formed on the other end of the connecting arm (66) and includes a square tube-shaped weight tube (92) extending outward from the other end of the connecting arm (66) and counterweights (94) inserted into the inner end of the extended portion of the weight tube (92).

[0045] At this time, the counterweights (94) are secured by pins (96) that protrude from the upper outer side of the weight tube (92) through the counterweights (94) to the lower outer side of the weight tube (92).

[0046] With this balance weight (90), the center of gravity of the rotary side blower (66) can be aligned with the rotation axis of the motor (68) for the drying device, thereby allowing the balance of the rotational movement of the rotary side blower (66) to be maintained while reducing vibration.

[0047] Meanwhile, the first moving carriage (70) is movably installed on a pair of guide frames (24) formed to extend along the longitudinal direction of the vehicle on the upper side of the frame (22) forming the washing bay (20).

[0048] Likewise, the second moving carriage (80) is movably installed on a guide frame (34) formed to extend along the longitudinal direction of the vehicle on the upper side of the frame (32) forming the drying bay (30).

[0049] To this end, driver motors (72, 82) are mounted on the inner front side of the first and second moving carriages (70, 80) respectively so as not to interfere with the motor (34) for the high-pressure injection device, the solenoid valve (not shown), the top blower (62), and the motor (68) for the drying device.

[0050] At this time, a pair of driving rollers (74, 84) are installed on the lower surfaces of the first and second moving carriages (70, 80) that are connected to the front of each driver motor (72, 82) and receive rotational force from each driver motor (72, 82) and roll along the guide frame (24, 34).

[0051] Here, the connection relationship between each driver motor (72, 82) and each driving roller (74, 84) is a known technology, so a detailed description thereof is omitted.

[0052] And on the lower surfaces of both ends connected to the rear of the first and second moving carriages (70, 80), a pair of idler-type driving rollers (76, 86) are installed to assist the movement of the first and second moving carriages (70, 80) by rolling along the guide frames (24, 34), respectively.

[0053] Additionally, on the upper surface of the guide frame (24, 34), a derailment prevention rail (26, 36) having a circular cross-section is installed to extend along the guide frame (24, 34), and on the driving type driving roller (74, 84) and the idler type driving roller (76, 86), a derailment prevention groove (78, 88) that fits into the derailment prevention rail (26, 36) is formed along the outer surface of the driving type driving roller (74, 84) and the idler type driving roller (76, 86).

[0054] Preferably, a drainage groove (not shown) that collects and removes moisture can be formed on the upper side of the anti-detachment rail (26, 36) and extends along the longitudinal direction of the anti-detachment rail (26, 36), and such drainage groove prevents slippage of the driving type driving roller (74, 84) and idler type driving roller (76, 86) caused by moisture settling on the anti-detachment rail (26, 36).

[0055] That is, since the driving type driving rollers (74, 84) and idler type driving rollers (76, 86) are installed on the lower surfaces of both ends connected to the front and rear of the first and second moving carriages (70, 80), the load of the first and second moving carriages (70, 80) is evenly distributed among the driving type driving rollers (74, 84) and idler type driving rollers (76, 86). This not only ensures the stability of the movement of the first and second moving carriages (70, 80) but also reduces wear on the driving rollers (74, 76, 84, 86), thereby extending the service life of the moving carriages (70, 80).

[0056] In addition, an anti-detachment rail (26, 36) is installed on the upper surface of the guide frame (24, 34), and an anti-detachment groove (78, 88) that fits into the anti-detachment rail (26, 36) is formed on the driving rollers (74, 76, 84, 86), thereby preventing the driving rollers (74, 76, 84, 86) from detaching and suppressing shaking of the first and second moving carriages (70, 80) that occurs during movement.

[0057] It is stated that the intrinsic technical concept of the present invention is not limited to the embodiments described above, but encompasses the scope that can be easily proposed by a person skilled in the art through substitution or modification.

[0058] Furthermore, since the terms used in the description of the present invention are selected for the convenience of explanation, in grasping the intrinsic technical concept of the present invention, they should not be limited to their dictionary meanings but should be appropriately interpreted in a sense consistent with the technical concept of the present invention.
