Specific details for implementing the invention

[0023] Hereinafter, an embodiment of a no-touch automatic car wash machine having a car wash vehicle collision prevention function according to the present invention will be described in detail with reference to the drawings.

[0024] FIGS. 1 to 5 are schematic drawings illustrating a no-touch automatic car wash machine related to the present invention.

[0025] Referring to FIGS. 1 to 5, 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] And the no-touch automatic car wash machine (10) according 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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) that controls the entire no-touch automatic car wash machine (10), 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 washed.

[0034] 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.

[0035] 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.

[0036] 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).

[0037] 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).

[0038] 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.

[0039] 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).

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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).

[0045] 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. The motors (68) for drying devices rotate the discharge port of the rotary side blower (64) along the outer edge of the vehicle so that it faces the vehicle, in accordance with a signal from a control system (not shown) that controls the entire no-touch automatic car wash machine (10). As a result, high-pressure drying air is discharged onto the top surface of the vehicle as well as both sides, the front, and the rear of the vehicle, thereby removing water from the vehicle.

[0046] 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.

[0047] 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.

[0048] 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).

[0049] 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).

[0050] 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.

[0051] 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).

[0052] 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).

[0053] 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.

[0054] 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).

[0055] Here, each driver motor (72, 82) is electrically connected to a control system that controls the entire no-touch automatic car wash machine (10), and since the connection relationship between each driver motor (72, 82) and each driving roller (74, 84) is a known technology, a detailed description thereof is omitted.

[0056] 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 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.

[0057] 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).

[0058] 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).

[0059] 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).

[0060] Additionally, 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.

[0061] And the no-touch automatic car wash machine (10) according to the present invention further includes a first collision prevention device (100) and a second collision prevention device (200) that detect in real time whether a car wash vehicle is properly stopped within the washing area in the washing bay (20) and the drying area in the drying bay (30).

[0062] The first and second collision prevention devices (100, 200) are each installed inside the washing bay (20) and drying bay (30) and are electrically connected to a control system that controls the entire no-touch automatic car wash machine (10).

[0063] The first and second collision prevention devices (100, 200) each include a first sensor unit (110, 210), a second sensor unit (120, 220), a third sensor unit (130, 230), a fourth sensor unit (140, 240), and a fifth sensor unit (150, 250).

[0064] The first sensor unit (110, 210), the second sensor unit (120, 220), the third sensor unit (130, 230), the fourth sensor unit (140, 240), and the fifth sensor unit (150, 250) are formed as conventional photoelectric sensors having a light-emitting unit and a light-receiving unit.

[0065] The first sensor unit (110, 210) is installed in the width direction (vehicle width direction) inside the entrance side of the washing bay (20) and the drying bay (30), respectively, and the second sensor unit (120, 220) is installed in the width direction inside the exit side of the washing bay (20) and the drying bay (30), respectively, and the third sensor unit (130, 230) is installed between the first sensor unit (110, 210) and the second sensor unit (120, 220), respectively, and is installed in the width direction adjacent to the second sensor unit (120, 220).

[0066] Additionally, the fourth sensor unit (140, 240) is installed in the longitudinal direction (longitudinal direction of the vehicle) inside the left side of the washing bay (20) and the drying bay (30), respectively, and the fifth sensor unit (150, 250) is installed in the longitudinal direction inside the right side of the washing bay (20) and the drying bay (30), respectively.

[0067] At this time, the first sensor unit (110, 210) detects the limit that the rear side (e.g., the rear bumper of the vehicle) of the vehicle that has entered the washing bay (20) and the drying bay (30) must not exceed, the second sensor unit (120, 220) detects the limit that the front side (e.g., the front bumper of the vehicle) of the vehicle that has entered the washing bay (20) and the drying bay (30) must not exceed, and the third sensor unit (130, 230) guides the stopping position of the vehicle that has entered the washing bay (20) and the drying bay (30).

[0068] And the fourth sensor unit (140, 240) detects the limit that the left side of the vehicle entering the washing bay (20) and drying bay (30) must not exceed, and the fifth sensor unit (150, 250) detects the limit that the right side of the vehicle entering the washing bay (20) and drying bay (30) must not exceed.

[0069] For example, if a vehicle parked inside the washing bay (20) and drying bay (30) is detected by the third sensor unit (130, 230) and not detected by the first and second sensor units (110, 210, 120, 220) and the third and fourth sensor units (130, 230, 140, 240), the control system determines that the vehicle is properly parked in the washing area within the washing bay (20) and the drying area within the drying bay (30), and thus the washing and drying operations are performed.

[0070] For example, when a vehicle parked inside the washing bay (20) and drying bay (30) is detected by the third sensor unit (130, 230) and by one or more of the first and second sensor units (110, 210, 120, 220) and the third and fourth sensor units (130, 230, 140, 240), the control system determines that the vehicle is not parked correctly in the washing area within the washing bay (20) and the drying area within the drying bay (30), and thus prevents washing and drying operations from being performed.

[0071] For example, while a vehicle is stopped inside a washing bay (20) and a drying bay (30) and performing washing and drying operations, if the vehicle is detected by a third sensor unit (130, 230) and by one or more of the first and second sensor units (110, 210, 120, 220) and the third and fourth sensor units (130, 230, 140, 240), the control system determines that the vehicle's position has moved out of the washing area and drying area and stops the washing and drying operations.

[0072] Here, the reason for setting limits that must not be exceeded by the vehicle through the first and second sensor units (110, 210, 120, 220) and the third and fourth sensor units (130, 230, 140, 240) is that there may be collisions with the rotary high-pressure spray pipe (42) and rotary side blower (64) that move along the outer edge of the vehicle during washing and drying operations, and the first and second sensor units (110, 210, 120, 220) and the third and fourth sensor units (130, 230, 140, 240) are each installed on the frames (22, 32) of the washing bay (20) and drying bay (30).

[0073] Preferably, if the vehicle is not properly stopped in the washing area of ​​the washing bay (20) and the drying area of ​​the drying bay (30), or if the vehicle moves out of the washing area and drying area during the washing and drying operations, the control system may request the driver to move the vehicle into the washing area and drying area via voice or video.

[0074] More preferably, a vehicle moving means (not shown) capable of moving a vehicle forward, backward, left, and right can be installed on the floor of the washing area of ​​the washing bay (20) and the drying area of ​​the drying bay (30), respectively, and if the vehicle is not properly stopped in the washing area of ​​the washing bay (20) and the drying area of ​​the drying bay (30), or if the vehicle moves out of the washing area and the drying area during washing and drying operations, the control system can operate the vehicle moving means to move the vehicle to the washing area and the drying area.

[0075] Meanwhile, the first and second collision prevention devices (100, 200) further include a sixth sensor unit (160, 260).

[0076] The sixth sensor unit (160, 260) is formed as a conventional distance sensing sensor, such as an ultrasonic sensor or an infrared sensor, unlike the first to fifth sensor units (110, 210, 120, 220, 130, 230, 140, 240, 150, 250).

[0077] The sixth sensor unit (160, 260) is installed on the first and second moving carriages (70, 80), respectively, and the sixth sensor unit (160, 260) detects a vehicle stopped inside the washing bay (20) and the drying bay (30).

[0078] That is, if the measurement value detected by the 6th sensor unit (160, 260) is shorter than the preset distance value, the control system determines that there is a vehicle inside the washing bay (20) and drying bay (30).

[0079] Preferably, the preset distance value refers to the distance from the sixth sensor unit (160, 260) to the bottom surface of the washing bay (20) and the drying bay (30).

[0080] Additionally, if a vehicle is not detected by the third sensor unit (130, 230) and the measurement value detected by the sixth sensor unit (160, 260) is shorter than a preset distance value, the control system determines that a vehicle is present inside the washing bay (20) and the drying bay (30).

[0081] Here, additionally checking for the presence of a vehicle through the 6th sensor unit (160, 260) is intended to detect vehicles with a short overall length, such as Smart ForTwo, micro electric vehicles, Classic Mini, etc.

[0082] The no-touch automatic car wash machine (10) according to the present invention formed in this way can detect the location of the vehicle in real time, thereby preventing collisions with the car wash equipment caused by vehicle entry errors and changes in vehicle location.

[0083] 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.

[0084] 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.
