Description

Technical Field

[0001] This utility model relates to a cleaning device for automobiles and vehicles, and more particularly to a modular car wash device. Background Technology

[0002] Cars and motorcycles are a common mode of transportation, and the dust they accumulate after prolonged use necessitates cleaning. While car owners with yards can wash their vehicles manually in their own backyards, urban residents often rely on commercially operated mechanical car washes.

[0003] Taking motorcycles as an example, a commercial mechanical car wash system provides a compartment through which motorcycles can enter and exit. This compartment contains a U-shaped, reciprocating gantry. Multiple water jet nozzles and air blowers are located on the sides and top frame of the gantry, capable of spraying high-pressure water or blowing air into the gantry. When a motorcycle to be washed is placed in the compartment, the gantry accommodates the motorcycle and reciprocates relative to it. Simultaneously, the water jet nozzles spray water jets or cleaning fluid to rinse the motorcycle, and after rinsing, the air blowers operate to remove residual moisture from the vehicle's surface. This commercial car wash system automates and facilitates the washing process, making it suitable for operation in densely populated urban areas. For structural features of this car wash system, refer to Taiwan Patent Publication No. I645995, "Car Wash Machine."

[0004] Regarding the existing car wash machine structure, the movement distance of the gantry is a predetermined value, which is the same for large, medium, and small vehicles. This often results in water jet washing or blowing exceeding the travel distance of the vehicle body, leading to waste of water and cleaning fluid. Furthermore, the wastewater generated from washing vehicles inevitably contains sand, which is difficult to remove. Moreover, the structure of the washing machine box is difficult to manufacture and inconvenient to transport and install.

[0005] Therefore, it is necessary to provide an effective spray washing system and a car wash equipment that is easy to manufacture, transport, install, and drain / dredge. Utility Model Content

[0076] Cooperate Figure 7 and Figure 8 , Figure 9 As shown (for ease of understanding the internal structure of the top unit 40, the sealing plate element at the top of the top unit 40 is exploded and no additional drawing numbers are shown), the top unit 40 is similar in shape to the base unit 20, and has a top end 422 and a bottom end 424 separated in a height direction, and a first end 426 and a second end 428 separated in a width direction, and a third end 421 and a fourth end 423 separated in a depth direction; the bottom end 424 of the top unit 40 also includes a transfer base 44 operably movable between its depth direction (the third end 421 and the fourth end 423), and the bottom of the transfer base 44 also includes a sprayer 46, which is operably rotatable relative to the transfer base 44.

[0077] In one feasible embodiment, the sprayer 46 has a transversely arranged horizontal support rod 462 and a longitudinal support rod 464 arranged longitudinally from one side end of the horizontal support rod 462. The sprayer 46 is rotatably implemented by the horizontal support rod 462 relative to the transfer base 44. The horizontal support rod 462 and the longitudinal support rod 464 have a plurality of nozzles 466 facing the angle between them. In a further feasible embodiment, a plurality of high-pressure jet nozzles (not shown in the figure) may also be implemented between the angled end faces of the horizontal support rod 462 and the longitudinal support rod 464.

[0078] In the embodiment shown in the figure, the horizontal support rod 462 and the vertical support rod 464 are connected tubular rods to provide liquid passage and spraying through the nozzle 466. The transfer base 44 is provided with a rotary passage joint 442 to provide rotation. The rotary passage joint 442 is connected to the horizontal support rod 462 through a shaft tube 468.

The rotary passage joint 442 is connected to a water inlet passage connected to a high-pressure water pump so that the sprayer 46 can perform high-pressure water spraying or spraying of mixed cleaning liquid or coating liquid.

[0079] Furthermore, the bottom end 424 of the top seat unit 40 has an air outlet 482 that provides high-speed airflow output, which is provided by a blower 48 disposed at the top end 422 of the top seat unit 40.

[0080] Regarding the movement of the transfer base 44 relative to the top seat unit 40, the top seat unit 40 has a pair of slide rails 41 extending between its third end 421 and fourth end 423 and spaced apart, and the transfer base 44 has a slide seat 446 at each end opposite to the pair of slide rails 41 that cooperates with them; the transfer base 44 is basically connected to at least one drive chain 432, which is implemented by two reel wheels 434. When the reel wheels 434 are subjected to a servo motor, When the drive mechanism 43 of the speed machine is driven to rotate, the transmission chain 432 will drive the transfer base 44 to move between the third end 421 and the fourth end 423 of the top seat unit 40. In the embodiment shown in the figure, the slide 446 is implemented by several longitudinal supports 448 on both sides of the width direction of the transfer base 44, so that the transfer base 44 is suspended below the transfer base 44. The extended ends of each support 448 are engaged with the transmission chain 432 to drive the transfer base 44 to move. In addition, the detection unit 70 can be provided on the lower end surface of the transfer base 44.

[0081] Cooperate Figure 10As shown, the door unit 30 has a pair of uprights 34 formed by the two sides of the passage 32, and a horizontal frame 36 formed between the tops of the two uprights 34. The passage 32 also includes a door 31 that can be operated to open or close the passage 32. The horizontal frame 36 is made of a frame covered with a panel and has an accommodating space 362. The door 31 is preferably a roller shutter controlled by a rotating motor, and the accommodating space 362 houses the roller shutter door 31. The two uprights 34 have a groove 342 on the travel path relative to the roller shutter door 31. In a preferred embodiment, the third end edge 221 of the base unit 20 forms a mating surface that engages with the door unit 30, and the third end 421 of the top seat unit 40 forms a mating surface that engages with the door unit 30.

[0082] The rear wall unit 50 is constructed by covering the frame with panel material. This rear wall unit 50 encloses the area between the fourth end edge 223 of the base unit 20 and the fourth end 423 of the top unit 40. The rear wall unit 50 can be a hollow shell with a storage space (not shown in the figure), and at least one vertical end face of the rear wall unit 50 can have at least one door panel, allowing the storage space to be either open or closed. This storage space primarily provides storage for equipment used in car washing, such as high-pressure water pumps or water control valves, detergent storage tanks, coating solution storage tanks, electrical control systems, and wiring boards. In a preferred embodiment, the fourth end edge 223 of the base unit 20 forms a mating surface that engages with the rear wall unit 50, and the fourth end 423 of the top unit 40 also forms a mating surface that engages with the rear wall unit 50.

[0083] The first sidewall unit 60 and the second sidewall unit 80 are used to enclose the two sides of the operating space 12 in the width direction, and are established in the area enclosed by the base unit 20, the top seat unit 40, the door unit 30, and the rear wall unit 50. In a feasible embodiment, the first sidewall unit 60 and the second sidewall unit 80 basically have a base plate 62 and 82. The top of each base plate 62 and 82 also includes a cover plate 622 and 822. The cover plate 622 and 822 can be made of a transparent material, such as glass or acrylic sheet. In order to cooperate with the implementation of the cover plate 622 and 822, the base plate 62 and 82 and the top seat unit 40, the door unit 30, and the rear wall unit 50 relative to the cover plate 622 and 822 have slots 64 and 84 to provide positioning for the cover plate 622 and 822.

Furthermore, the base plates 62 and 82 have a pair of side end surfaces 624 and 824 separated in a lateral direction, and these side end surfaces 624 and 824 form a mating surface that engages with the door unit 30 and the rear wall unit 50.

[0084] Regarding the operation of the car wash equipment 10, this utility model also includes a control unit 90 for programmable control of the operation of the device. The control unit 90 controls the operation of the electromechanical equipment in the car wash equipment 10, and may further include an operation panel 92 to provide consumers with the operation and payment for using the car wash equipment 10, or to enable technicians to set up and maintain the equipment. As for the motor control technology, it is prior art and will not be elaborated on in this article.

[0085] As can be seen from the above description, the car wash equipment 10 of this utility model features a convenient modular design. Its base unit 20, top unit 40, first side wall unit 60, second side wall unit 80, door unit 30, and rear wall unit 50 can be prefabricated in the factory. Moreover, the docking points of each unit provide a convenient mating surface, so that each unit of this utility model can be conveniently transported to the installation site for assembly and wiring after being manufactured in the factory to complete the installation of this utility model. In addition, in addition to the advantages of convenient manufacturing and transportation, the modular design also makes it easy to install in narrow environments, such as in shops on the ground floor of commercial areas.

[0086] Based on the structural features of this utility model, in the cleaning operation of motorcycles and vehicles, after the vehicle is moved into the operating space 12, the detection unit 70 will detect the width, height, length, and parking position of the vehicle in the operating space 12. If the parking position of the vehicle affects the movement of the sprayer 46 on the transfer base 44, the control unit 90 can issue a warning to remind the user to make corrections. The vehicle's external dimensions and position information detected by the detection unit 70 is obtained by the control unit 90. Based on the obtained information, the control unit 90 controls the transfer base 44 to make the optimal movement stroke, and the sprayer 46 also rotates to the most appropriate position. In this way, when the sprayer 46 sprays cleaning liquid or performs high-pressure water washing, these actions can be correctly applied to the vehicle position, without problems of applying the sprayer outside the vehicle position or failing to apply it to the vehicle position, thus improving the efficiency of car washing.

[0087] The initial position of the transfer base 44 can be near the fourth end 423 of the top unit 40. The longitudinal support rod 464 of the sprayer 46 is located on the side of the first end 426 or the second end 428 of the top unit 40. During operation, if the front of the vehicle is facing the fourth end 423 at the depth of the top unit 40, the transfer base 44 moves from the fourth end 423 to the third end 421. The nozzles 466 in the horizontal support rod 462 and the longitudinal support rod 464 of the sprayer 46 can select the output liquid via a water control valve, depending on the liquid selected by the control unit 90. The water can be mixed with the cleaning agent storage tank to spray the cleaning liquid on one side of the vehicle. When the transfer base 44 moves to the rear of the vehicle detected by the detection unit 70, the sprayer 46 rotates, causing the longitudinal support rod 464 to rotate outward toward the vehicle. On the other side, during the rotation, each nozzle 466 in the longitudinal support rod 464 sprays the rear of the vehicle and then continues to move towards the fourth end 423. When the transfer base 44 moves to the front of the vehicle detected by the detection unit 70, the sprayer 46 rotates outward again, causing each nozzle 466 in the longitudinal support rod 464 to spray the front of the vehicle, thus completing a cleaning process. After waiting for the cleaning agent to react, the transfer base 44 will perform a cleaning process according to the settings of the control unit 90. At this time, the control unit 90 can operate the control switching valve to cut off the common passage of the cleaning agent and select to perform a rinsing operation with clean water. The horizontal support rod 462 and each nozzle 466 in the longitudinal support rod 464 of the sprayer 46 will spray clean water to remove the cleaning fluid adhering to the vehicle.

[0088] Multiple cleaning processes can be set by the control unit 90, such as: a high-pressure water rinse after spraying cleaning fluid, followed by a water coating spray and another high-pressure water rinse. After the liquid cleaning process, the transfer base 44 can move again between the third end 421 and the fourth end 423. At this time, the blower 48 will operate, and the high-pressure air generated will be blown out of the air outlet 482 toward the vehicle to blow away the water droplets remaining on the vehicle surface. Of course, as mentioned earlier, the high-pressure blowing can also be accomplished by installing several high-pressure air nozzles connected to an air compressor on the longitudinal support rod 464 or the transverse support rod 462 and the longitudinal support rod 464 of the sprayer 46.

[0089] Regarding the wastewater generated during vehicle washing according to this invention, the wastewater can flow into the water collection tank 24 through the drain holes 212 in the cover plates 21 on both sides of the base unit 20 bearing plate 28, and be discharged outward through the drainage channel 242. The water collection tank 24 is designed to buffer the instantaneous large volume of water required during washing operations. When the drainage channel 242 cannot quickly discharge the wastewater, the water collection tank 24 can provide temporary retention for the wastewater. Of course, the drainage channel 242 can also be connected to a drainage passage equipped with a water pump (not shown in the figure) to increase the drainage speed. Furthermore, the wastewater contains silt during vehicle washing. The silt in the wastewater can be deposited in the water collection tank 24, and the remaining silt can be cleaned after removing the cover plate 21, so that the wastewater under this invention will not cause the risk of clogging the drainage pipe.

[0090] In the embodiment shown in the above figures, a water collection tank 24 is distributed over a large area within the implemented base unit 20. This structural feature presents inconvenience during sludge removal operations due to the extensive sludge distribution area and limited footholds. In another feasible embodiment, such as... Figure 11 As shown, the base unit 20 has two water collection troughs 24 formed on both sides of a first end edge 226 and a second end edge 228 in its width direction, and a support plate 28 is provided between the two water collection troughs 24. Each water collection trough 24 has an open end 244, and each water collection trough 24 also includes at least one drainage channel 242 communicating with the outside of the base unit 20. The open end 244 of each water collection trough 24 is covered by a cover plate 21 with multiple drainage holes 212. In this way, when removing deposited silt, personnel can step on the support plate 28 to work on the water collection troughs 24 on both sides, which has the advantage of providing convenience for construction.

[0091] With the structural design of this utility model, the detection unit 70 set in the operating space 12 can accurately perform vehicle cleaning operations after detecting and knowing the parking position, appearance size and other information of the vehicle to be cleaned, so that the car wash equipment 10 of this utility model can greatly reduce the waste of cleaning agents, water and other materials.

[0092] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, those skilled in the art to which this invention pertains can implement it in other specific forms without altering the technical concept or essential features of the present invention. Therefore, the embodiments described above are for illustrative purposes only and are not intended to be limiting.
