Description

Technical Field

[0001] This application belongs to the field of automotive cleaning technology, specifically relating to a car wash booth suitable for underground garages. Background Technology

[0002] With the increasing scarcity of urban land resources and the pollution and noise pollution inherent in the car wash industry, car washes are currently trending towards being located in underground parking garages of shopping malls, office buildings, and residential buildings. Traditional car washes in underground garages are typically situated in corners or against walls, employing manual or semi-manual cleaning methods. In these types of car washes, vehicles typically enter and exit in the same direction; entering is normal, but exiting requires reversing, or vice versa. Clearly, this design is not conducive to automated, unattended cleaning and negatively impacts the user experience. This is especially true for single-lane underground garages, where turning directly into the car wash from the front is even more difficult. Therefore, utilizing multiple parking spaces to create car washes with one-way entrances and exits is a preferred solution for unattended operation. Currently, the width and length of straight parking spaces in underground garages are typically 2.2–2.5 meters × 5–5.5 meters. Underground garages also have numerous column grid structures. Based on the building's load-bearing capacity, the most economical column spacing is generally set at around 7.5 meters. Thus, in the width direction, three consecutive parking spaces are each fixed with a column on both sides, and in the length direction, two parking spaces are also designed with columns. Therefore, the 3×2 (6 spaces in total, double rows) parking space has become a common design. For a 3×2 consecutive parking space, there are four columns at the four corners of the rectangle. Since the length of the parking space exceeds 7.5 meters, an additional column is added in the middle. Due to the actual height limitations of underground garages (generally around 2.5 meters), the traditional gantry structure is usually not suitable. Constructing a side-mounted cleaning system with sliding rails is a better choice. However, vehicle lengths vary, with most around 4.6 meters and the longest reaching 5.5 meters. To meet versatility requirements, the rail... The track length should be greater than the maximum length of a regular sedan to allow for scanning and cleaning of the front and rear of the vehicle. Experiments have shown that a track length of around 7.5 meters is suitable. Furthermore, the entrance space before entering the cleaning area should have sufficient depth to allow vehicles to turn in. For driving lanes, calculations show that a certain depth and turning radius are required if a vehicle wants to enter directly from the front. A wider and deeper entrance space makes entry easier for users. However, for a single-lane driving lane, the minimum entrance depth is approximately 3.9 meters, and the minimum width (limited by the maximum turning radius) is approximately 4.11 meters. Clearly, with a 3x2 parking space, excessive entrance depth and width negatively impact the layout of the cleaning machines. Machine deployment must consider track length, ensuring compatibility with different vehicle lengths, and the width between tracks to account for machine eccentricity. Wider track spacing necessitates higher eccentricity design requirements, making machine deployment more difficult.Considering economic costs and the underground parking garage's column grid environment, how to design an unattended car wash suitable for underground parking garage environments by utilizing effective parking space areas, allowing users to easily turn into the washing area for vehicle washing, and having strong versatility to meet the washing needs of different types of vehicles, is a technical problem that needs to be solved. Summary of the Invention

[0003] The purpose of this application is to provide a car wash room suitable for underground garages, which makes it more convenient for users to drive into the vehicle washing space.

[0004] Based on the above objectives, some embodiments of this application provide a car wash room suitable for underground garages, including a room that can be installed in an underground garage. The room includes an entrance enclosure, an exit enclosure, and a partition connecting the entrance enclosure and the exit enclosure. The entrance enclosure, the exit enclosure, and the partition form a vehicle washing space. The entrance enclosure defines the vehicle washing space with its entry direction inclined relative to the driving direction of the lane on one side of the entry direction.

[0005] In some embodiments, the exit direction of the vehicle washing space defined by the exit enclosure is inclined relative to the driving direction of the lane on the side of the exit direction.

[0006] In some embodiments, the enclosure further includes an equipment room located on one or both sides of the vehicle washing space.

[0007] In some embodiments, the building body further includes a front facade, a rear facade, a left facade, and a right facade, and the partition, together with the front facade, rear facade, left facade, and right facade, forms an equipment room.

[0008] In some embodiments, the car wash also includes an entrance channel that guides the vehicle from the driveway into the vehicle washing space, the entrance channel being configured such that the steering wheel angle of the vehicle turning from the driveway into the entrance channel is less than 90 degrees.

[0009] In some embodiments, the direction of entry into the vehicle washing space defined by the entrance enclosure is consistent with the direction in which the vehicle enters from the entrance passage.

[0010] In some embodiments, the entrance passage is an open space or formed by a solid physical surface.

[0011] In some embodiments, the entrance passage has a depth of 2-3 meters and has inner facades of two solid structures extending toward the entrance enclosure.

[0012] The inner facade that the vehicle passes first when driving in the underground parking garage driveway is an inclined plane, and the angle formed between the inclined plane and the first opening of the building is less than 90 degrees.

[0013] Alternatively, the inner facade that is passed first is a curved surface. When the inner facade is a curved surface, the angle between the tangent of the curved surface and the first opening surface of the building is less than 90 degrees.

[0014] In some embodiments, the car wash also includes an exit passage that guides vehicles from the vehicle washing space to the driveway. The entrance passage and the exit passage are located on opposite sides of the vehicle washing space. The exit passage is an open space or is formed by a solid physical surface.

[0015] In some embodiments, the car wash can be located within a designated area, which is the area defined by the 3×2 parking spaces of the underground garage, or the designated area is 10-11 meters long and 6.6-7.5 meters wide.

[0016] The car wash enclosure applicable to underground parking garages using the method described in this application achieves the following technical effects:

[0017] 1. The entrance enclosure, exit enclosure, and partitions of the car wash room form a vehicle washing space with the driving direction inclined relative to the driving lane on the side of the driving direction. Compared with the setting where the driving direction is perpendicular to the driving lane, this inclined setting makes it easier for drivers to turn from the driving lane into the vehicle washing space.

[0018] 2. The car wash in this application is based on the characteristics of narrow driveways and multiple straight parking spaces side by side in underground garages, as well as the limitations of column grids. It forms a car wash with a slanted layout within the space enclosed by multiple parking spaces. After the user's vehicle scans the code and pays through the entrance channel, it can naturally drive into the vehicle washing space inside. After the robot completes the entire washing and drying process, it can naturally drive out through the exit channel. The whole process is simple, highly feasible, and provides a high level of user experience.

[0019] 3. Considering the track length of the vehicle washing equipment, the different lengths of different vehicles, the length of the entrance and exit passages, and the length relationship of the parking spaces, this application adopts multiple connected standard straight parking spaces to establish an unattended automated car wash room. The vehicle washing space is laid out diagonally, that is, along a diagonal of the room. The track length is large enough and the versatility is strong, which can meet the washing needs of cars of different lengths and widths on the market.

[0020] 4. The car wash entrance channel of this application has an angle of less than 90 degrees between one of the inner facades and the first opening of the adjacent side of the building. This guides vehicles to turn into the entrance channel from the driving lane (perpendicular to the parking space direction) on the side adjacent to the inner facade with a steering wheel angle of less than 90 degrees. In this way, even when driving in a single-lane driveway in the underground parking garage, users can easily turn into the entrance channel in one go without having to make multiple adjustments, greatly enhancing the user experience.

[0021] 5. The angled entrance passage design of this application provides users with ample adjustment space after turning into the entrance passage, and the entrance passage is deep enough. The entrance passage gradually narrows from the outside to the inside of the chamber, which facilitates the physical guidance of the user's driving path and makes it easy to guide the user to park the car in the middle of the vehicle washing area. The exit passage gradually widens from the inside to the outside of the chamber, which provides a wide enough field of vision when the vehicle drives out, making it easy to observe the road conditions ahead and also making it easier for the rear of the vehicle to avoid collision when the user turns.

[0022] 6. This application provides a long limiting rod or a visually visible limiting area between the two tracks in the vehicle washing space to further limit the distance between the vehicle and the washing equipment on the left and right tracks, thereby improving the safety of unmanned washing.

[0036] This embodiment provides a car wash enclosure suitable for underground parking garages. This car wash enclosure is primarily suitable for low-ceilinged spaces such as underground parking garages. Building a car wash enclosure in an underground garage requires comprehensive consideration of various factors, including garage height, column grid structure, parking space size, vehicle access convenience, waterproofing and noise reduction, space for washing machines, equipment storage space, and the length, width, and height of different vehicles. Figure 1As shown, this application leverages the universality of standard straight parking spaces in existing underground garages, connecting two rows of six straight parking spaces into a single rectangular car wash structure. The four corners of the rectangular structure are located at the four pillars of the underground garage. This car wash is an unattended, machine-controlled intelligent car wash. When a user is driving in the underground garage driveway (arrows indicate the vehicle's direction of travel), they can easily turn into the entrance space in front of the washing area. After scanning a code to pay or verifying a voucher, the entrance barrier opens, allowing the vehicle to enter the washing area. The vehicle then stops and the image sensors and radar begin scanning and modeling the vehicle to generate a washing path. Cleaning instructions are then sent to the cleaning robot on the track. The robot follows the instructions to complete the automated process of spraying chemical agents, high-pressure water rinsing, and drying. Finally, the exit barrier automatically opens, allowing the vehicle to exit directly from the other side. The entire washing process takes only 6-9 minutes, significantly reducing the user's waiting time.

[0037] like Figures 2 to 3 As shown, the car wash in this embodiment includes a rectangular structure formed by connecting 3×2 parking spaces. It has a front exterior facade 81, a rear exterior facade 91, a left exterior facade, and a right exterior facade, and is closed on the outside. The front and rear exterior facades 81 and 91 are adjacent to a driveway. The edge of the car wash coincides with the outer edge of the parking space lines of the connected area. The width of the car wash (in the driveway direction) is the sum of the widths of three parking spaces, the length is the sum of the lengths of two parking spaces, and the height is determined based on the underground parking garage height. The length, width, and height of the car wash can be adjusted according to actual needs. For example, refer to... Figure 5 As shown, when a car wash is needed to wash two cars simultaneously, a single connected car wash includes two independent vehicle washing spaces 31, as well as two independent entrance passages 11 and exit passages 21. In this case, the length and height of the wash remain unchanged, but the width is increased, for example, to 10-15 meters. This allows for the simultaneous washing of two vehicles, and the two vehicle washing spaces 31 can share the same central equipment room. In this embodiment, the wash includes the internal vehicle washing spaces 31, and the top of the vehicle washing spaces 31 can be open or closed.

[0038] Reference Figure 2 , Figure 3As shown, the rectangular enclosure in this embodiment has an inclined vehicle washing space 31, which is formed by an entrance enclosure 318, an exit enclosure 319, and two isolation members 312 connecting the entrance enclosure 318 and the exit enclosure 319. The isolation members 311 are made of a sealed waterproof material or a water-absorbing material, including one or a combination of solid walls, waterproof wooden boards, waterproof plastic boards, or waterproof glass boards, or water-absorbing fabric. The entrance enclosure 318 and the exit enclosure 319 can both be programmed electric roller shutter doors or electric gate doors. Since a large amount of moisture and noise will be generated in the space during washing, and in order to take safety into consideration, the sealed structure in the form of electric doors is preferred. Inside the enclosure, two parallel, diagonally arranged tracks 312 are fixedly installed for the movement of the cleaning machine. The diagonal direction is relative to the two sides of the parking space. The tracks 312 are located on a platform between the two spacers 311, or fixed to the spacers 311, or suspended from the top of the cleaning space between the two spacers 311. Given that the machine's movement along the tracks affects the overall structural eccentricity, and considering the height limitations of the parking garage, it is preferable to lay the tracks on a platform on the ground, with the vehicle parked between the two tracks 312. On the platform, the acute angle β formed by the track 312 and the driveway at the entrance / exit of the vehicle washing space 31 is 60-90 degrees. If the inclination is too low, it reduces the length of the track and the washing space. Therefore, a preferred angle is 70-80 degrees, set as an angle. On the one hand, this facilitates the small-angle entry of vehicles; on the other hand, it can also accommodate vehicles of different lengths or widths to the greatest extent, making it highly versatile. The inclination direction is the direction from the corner of the building that the vehicle passes first when traveling from the driveway according to the ground markings to the opposite corner of the cuboid. (Refer to...) Figure 2 As shown, when a vehicle enters from the lower lane from right to left, the tilt direction is from the lower right corner to the upper left corner, as shown. Figure 4 As shown, when a vehicle enters from the lower lane from left to right, the tilt direction is from the lower left corner to the upper right corner. The isolation component 311, together with the front facade 81, rear facade 91, left facade, and right facade, forms an independent storage equipment room 41. This equipment room 41 is a room space other than the vehicle washing space 31. The equipment room 41 mainly houses some high-pressure water tanks, chemical mixing cabinets, or other raw materials and supplies, which are used for cleaning the machinery and equipment on each side. There can be one or two equipment rooms 41.

[0039] Furthermore, two isolation members 311 stand vertically on the ground, diagonally positioned relative to the parking lines and parallel to each other. Entrance barriers 318 and exit barriers 319 are also diagonally positioned and parallel to each other, together enclosing an obliquely oriented vehicle washing space (with a parallelogram cross-section), confining vehicles to a specific area and parking direction. Further, entrance barriers 318 and exit barriers 319 are perpendicular to the isolation members 311, forming a rectangular cross-section for the vehicle washing space. Preferably, the vehicle washing space 31 is inclined along one diagonal of the rectangular structure, thus maximizing usable space while meeting the necessary entrance depth and track length requirements. It should be noted that this diagonal direction is approximate; due to the presence of columns at the diagonal, the extended line of the track does not intersect with the column positions at the corners of the cuboid, but rather maintains a short distance. The height of the isolation members 311 is approximately equal to the height of the left and right exterior facades. The height of the isolation component 311 is roughly the same as the height of the left and right exterior facades. The isolation component 311 is designed to prevent the liquid sprayed by the cleaning machine on the opposite track 312 from overflowing to both sides and can also play a role in water and sound insulation. Therefore, the isolation component 311 is not limited to a straight line. For example, it can be designed as a retractable foldable shape or a curved surface with a certain curvature, which can also achieve the effect of water and sound insulation. Because existing vehicles vary in length, if the vertical direction of the traditional straight parking space is used as the vehicle washing space 31, for some longer vehicles, such as the Lexus LX, Lincoln Navigator, and Patrol, the only solution is to reduce the depth of the entrance and exit passage or increase the length of the car wash booth. This would occupy more parking spaces or public space, increasing costs. Moreover, the machine needs to slide along the track to collect and clean images of the vehicle's exterior, especially the front and rear. Therefore, the track length is generally greater than the vehicle length. The track length in this application is 6.5 to 8 meters, preferably 7 to 7.5 meters, which is about 2 meters longer than the longest sedan (5.5 meters). Therefore, the length of the track itself also limits the length of the entire washing space. However, the diagonal layout of the track solves this problem. It is convenient for users to drive in and has universality, which can meet the washing needs of vehicles of different lengths and widths on the market. In addition, the width between the two tracks is designed to be between 2.2 and 3.6 meters (based on the exterior facade), with 2.8 meters being preferred, which can basically meet the width of common vehicles on the market. This application, by arranging the vehicle washing space 31 obliquely, allows for a longer parking space within the same usable area, thus accommodating a wider variety of vehicles. Furthermore, the entrance and exit passages can be made deeper, providing users with a certain turning radius and making it easier for vehicles to enter and exit. It is highly versatile and suitable for large-scale deployment of underground parking garage car washes in unmanned mode.

[0040] The track 312 is relatively close to the isolator 311. The cleaning machine on the track 312 has multiple free arms facing the vehicle body. More preferably, two opposing long limit bars 313 are fixed on the ground between the two tracks 312 to limit the parking position of the vehicle. The two long limit bars 313 are also parallel. The vehicle needs to be parked between the two long limit bars 313. The parallel distance between the two long limit bars 313 can at least meet the width of most cars or ordinary SUVs. The long limit bars 313 also have a distance from the tracks 312 on the left and right sides, leaving space for the robot's free arms to clean without contact and reducing the risk of accidental collision. The long limit bars 313, the track 312, and the isolator 311 are all obliquely arranged and parallel to each other. Setting a long limit bar 313 allows users to directly perceive the position through the rearview mirror or tires. Alternatively, limit marking lines can be drawn on the ground between the two tracks 312 to replace the function of the long limit bar. The limit marking lines can be marked with darker colors such as yellow or red. The limit marking lines can form a parallelogram area or be set only on the left and right sides.

[0041] In addition, in this application, the interior floor of the vehicle washing space 31 can also be provided with a platform higher than the garage floor. The platform has multiple through holes, and the front and rear ends of the platform connecting the entrance and exit passages are small ramps. The long limit rod 313 and the track 312 can be installed on the platform. The waste liquid generated after washing is buffered and stored from the platform or discharged into the sewer after purification.

[0042] As a preferred embodiment of this invention, the car wash also includes an entrance channel 11 to guide vehicles into the vehicle washing space 31. Since vehicles need to scan a code to pay or verify payment before entering the car wash, users need to operate their mobile phones while in the driver's seat. However, the front of the car has a certain length, making it more difficult to drive directly, especially for single lanes. Therefore, an entrance channel 11 with a certain depth is specially designed to accommodate at least the front of the car. For single lanes, the depth of the entrance channel 11 needs to be designed to be at least 2 meters to allow for a better user experience when turning in. Otherwise, multiple adjustments are required. To accommodate the characteristics of single lanes and track length, a depth of 2 to 2.6 meters is preferable. If a straight parking area is used, the depth of the entrance space and the turning radius of the vehicle will increase when the user turns and parks straight. This is not suitable for parking areas formed by a grid of columns in a garage scenario and also affects the user's driving experience. The entrance passage 11 has a first side facing the driveway, which is an opening. One side of the opening is flush with the driveway boundary and relatively wide to facilitate vehicle entry. The second side of the entrance passage 11 (equivalent to the entrance door of the vehicle washing space 31), facing the interior of the vehicle washing space 31, is relatively narrow to guide the user's vehicle towards the center of the vehicle washing space 31, facilitating subsequent machine image scanning and cleaning processes. The second side of the entrance passage 11 is equipped with a program-controlled electric door, such as an electric roller shutter door, the surface of which can be covered with an adhesive waterproof film. Specifically, in one embodiment, the entrance passage 11 includes two opposing interior facades extending from the first opening towards the interior of the room: a first interior facade 111 and a second interior facade 112. The interior facades can be solid walls or panel materials. For ease of explanation, this embodiment defines the interior facade that the vehicle passes through first as the first interior facade 111. The advantage of having interior facades is that they create a more obvious physical guiding angle.Depending on the vehicle's direction of travel, when the first inner facade 111 is closer to the driver's side for scanning the code, the second inner facade 112 is closer to the passenger side. Since parking spaces in underground garages are usually perpendicular to the driveway, users of self-service car washes need to drive their vehicles forward (not backward) into the car wash area. However, most driveways in underground garages are one-way streets, making it virtually impossible to turn directly into a straight parking space in one go. To facilitate users turning into the car wash area, this application connects the inner facade that the vehicle passes first during its journey in the driveway (i.e., the side closest to the vehicle turning) with the first opening surface of the entrance passage 11 (a vertical surface perpendicular to the ground driveway). The included angle α of the inner facade is set to be less than 90 degrees, preferably 60 to 80 degrees. In this way, the included angle formed by it and the front outer facade 81 of the adjacent building is greater than 90 degrees, but should not exceed 130 degrees, preferably 100 to 120 degrees. This ensures that the steering wheel angle of the vehicle turning from the driveway near the inner facade into the entrance passage 11 is less than 90 degrees. Combined with the angle of the track and the vehicle cleaning space, the turning angle of the user from the entrance passage 11 to the cleaning space 31 is very small, which greatly reduces the inconvenience of the user driving in. The included angle between the other inner facade, namely the second inner facade 112 and the outer facade of the adjacent building can be set to 60 to 120 degrees, that is, it can be an acute angle, a right angle or an obtuse angle.

[0043] For example, refer to Figure 1 As shown in the diagram, the arrows indicate the vehicle's direction of travel. When a vehicle is traveling from right to left in the driving lane and needs to turn right to enter the car wash, the vehicle will pass first along the right-side inner facade. Therefore, the first inner facade 111 on the right is inclined, with an acute angle between it and the first opening face, and an obtuse angle between it and the right side of the adjacent building's front outer facade 81. The left side serves as the second inner facade 112, which can be equipped with an electronic display screen to display relevant information and allow users to scan a code to pay or verify their identity. (Refer to...) Figure 3 As shown, when a vehicle is traveling from left to right in the driving lane and needs to turn left to enter the car wash, the left inner facade is tilted, with the angle between it and the left side of the front outer facade 81 of the car wash being greater than or equal to 90 degrees. The electronic display screen is also located on this first inner facade 111. A preferred solution is to set the angles between the first inner facade 111 and the second inner facade 112 and their respective adjacent front outer facade 81 to be greater than 90 degrees, for example, around 100 degrees, as shown in Figure 6. In this way, regardless of whether the driving lane direction is from left to right or from right to left, it satisfies the user's vehicle's need to conveniently turn into the side entrance passage 11.

[0044] After a vehicle is cleaned in the cleaning space, it needs to leave the cleaning space. If the exit is directly flush with the rear exterior facade 91 of the enclosure, it is inconvenient for users to observe the driving lane environment at the exit in advance. Therefore, this application also provides an exit channel 21 on the rear exterior facade 91 of the enclosure to guide vehicles out of the vehicle cleaning space 31. The exit channel 21 also has a certain depth, but it is small to facilitate the swinging of the rear of the vehicle. The exit channel 21 also has a second opening facing the driving lane and a second side close to the vehicle cleaning space. The exit channel 21 gradually widens from the inner side (second side) of the enclosure to the outer side (first side), which makes it convenient for users to observe the lane conditions to the left and right front of the exit when driving out of the car wash. The field of vision is increased, and the turning radius of the vehicle is also increased, making it easier to drive out of the driving lane turning to the outside. An electric door is also provided near the vehicle cleaning space 31 at the exit channel 21. When the user's vehicle begins to be cleaned in the cleaning space, the electric doors at the entrance and exit are closed under the control of the system to prevent the liquid from flowing out during the cleaning process. The diagonal layout of the vehicle washing space should be basically consistent with the diagonal direction in which the vehicle enters from the entrance passage. This way, the steering wheel adjustment range is smaller when the vehicle enters the washing space. The entrance passage 11 is located near the corner of the front outer facade 81, and the exit passage 21 is located near the corner of the rear outer facade 91. The two corners are opposite corners of a cuboid, which maximizes the operating space.

[0045] In this embodiment, the entrance channel 11 gradually tapers from its outer end (first surface) to its inner side (second surface). The end opening of the entrance channel 11 (i.e., the second surface) is located between the widths defined by the two partitions 311. The two inner surfaces of the entrance channel 11 can be parallel to or form a certain acute angle with the partitions 311 on the same side. Figure 1 As shown, assuming the vehicle is coming from right to left, it should turn right into the car wash. At this time, the entrance of the entrance passage 11 is biased to the right corner of the front outer facade, and the angle between the first inner facade 111 on the right and the adjacent isolation piece 311 is approximately between 10 and 25 degrees.

[0046] However, it is undeniable that the structures of the inlet channel 11 and outlet channel 21 in the embodiments of this application are not limited to those of other applications. Figure 1 The structure shown, in an example shown in Figure 6(a), does not have physically significant guide ramps for obvious inlet and outlet channels, compared to... Figure 1As shown, the entrance and exit spaces of the cleaning area are made relatively large. The inner facade, which serves as a guide, has been removed. The walls or obstructions between the cleaning entrance and the first opening surface have been eliminated, as shown in the lower right corner of Figure 6 (the dotted line in the figure represents an open surface without obstructions). Similarly, a portion of the walls or obstructions between the cleaning exit and the second opening surface has been removed, as shown in the upper left corner of Figure 6 (the dotted line in the figure represents an open surface without obstructions). This results in a completely open section of the structure from the corner pillar to the cleaning opening. When a vehicle enters, it can directly see the location of the cleaning entrance door, facilitating entry into the cleaning space. When exiting the cleaning space, there are no obstructions from walls or obstructions, providing a better view. This design also meets the needs of vehicles entering, cleaning, and exiting normally. Of course, it is undeniable that the entrance and exit channels in this embodiment can also be made open, that is, there is no physical guide surface outside the entrance and exit doors of the vehicle washing space, and the whole is made into an open surface, as shown in Figure 6(b). Compared with the structure shown in Figure 6(a), the entrance and exit channels in Figure 6(b) do not actually exist, that is, there are no two inner facades formed by physical structures, and the whole is made into an open surface. In this case, turning indicator lines can be marked in the entrance space or plastic traffic cones can be used to limit the direction of entry.

[0047] The design of the interior facade provides a more intuitive physical guide to when the user should begin turning the steering wheel, while also increasing the storage volume between equipment compartments and improving overall space utilization. The interior facade that the vehicle passes over first during driving can be a single inclined plane or an irregular surface composed of several inclined (including vertical) planes. The angle between each inclined plane and the first opening should be acute. This ensures that the overall inclination of the irregular surface forms an acute angle with the first opening, facilitating turning for the user. For example, refer to... Figure 4 As shown, when a vehicle travels from left to right and turns into the car wash, an inclined transition section 61 is added between the original first inner facade and the front outer facade 81 of the adjacent side building where the vehicle turns. This turns the original one corner into two or even more corners. The angle between the transition section 61 and the adjacent inner facade, and the angle between the transition section 61 and the front outer facade 81 of the adjacent side building, are both greater than 90 degrees. Adding the transition section 61 can further improve the difficulty of the vehicle turning in and make the turn smoother.

[0048] Reference Figure 7 , Figure 8 As shown, when the first inner facade is composed of several short and inclined plane segments, it can be abstracted into a curved surface, such as... Figure 7As shown, the inner facade that a vehicle passes over first while driving in the lane is no longer a flat surface, but a curved surface, where, for example... Figure 8 As shown, the arc angle of the curved surface is an acute angle, or in other words, the angle between the tangent of the curved surface and the first opening surface (equal to the arc angle) is an acute angle. Considering that the entrance passage is generally located at the corner of the cuboid car wash, which facilitates the formation of an oblique space, if the first inner facade is a curved surface, the arc angle can be set to 15~35 degrees. This structure also makes it easy for vehicles to turn in.

[0049] Of course, the first interior facade can also adopt a structure combining inclined planes and curved surfaces, which will not be elaborated here. In principle, the design of the first interior facade is mainly to facilitate the guidance of user vehicles into the cleaning space. Therefore, whether it is designed as an inclined plane or a curved surface with an acute angle to the first opening surface, or the first interior facade is completely abandoned and an open space is created, with prominent route signs in this space, this requirement can be met.

[0050] Compared with existing technologies, the car wash booth in this application embodiment, suitable for underground garages, takes advantage of the low ceiling and narrow driveway characteristics of underground garages. The track is laid out diagonally along one diagonal of a cuboid, thus forming a slanted cleaning area. This provides a sufficiently large and deep entrance space for vehicles entering the cleaning area, allowing users to directly drive in without reversing or making multiple adjustments. Furthermore, it is highly versatile, accommodating different types of cars. After washing, users can directly exit through the exit passage, making it quick and convenient. The entire car wash booth has a compact and small structure, taking user convenience into account and making full use of the space layout. It is relatively economical in cost and provides a superior user experience.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
