[0008] [Figure 1] This is a top view of a car wash machine according to Embodiment 1. [Figure 2] This is a schematic front view of the car wash machine according to Embodiment 1. [Figure 3] This is a partial top view of the car wash machine according to Embodiment 1, showing the spray from the pit washing unit. [Figure 4] Figure 3 is a cross-sectional view taken along the line IV-IV. [Figure 5] This is a schematic diagram showing the configuration of the bottom cleaning device according to Embodiment 1. [Figure 6] This is a schematic diagram showing the configuration of the bottom cleaning device according to Embodiment 2. [Modes for carrying out the invention]

[0009] [Embodiment 1] The car wash machine 100 according to Embodiment 1 will be described below with reference to Figures 1 to 5. In the following description and the attached drawings, the vehicle length direction of a vehicle X parked in the car wash area G is defined as the front-rear direction. At this time, the direction of travel of a vehicle X entering the car wash area G is defined as the front, and the direction of reverse is defined as the rear. The vehicle width direction of the vehicle X is defined as the width direction, and the vehicle height direction of the vehicle X is defined as the up-down direction. The up-down direction is perpendicular to the front-rear direction and the width direction, and the front-rear direction is perpendicular to the width direction. The width direction may also be interpreted as the left-right direction.

[0010] Figure 1 is a top view of the car wash machine 100. The car wash machine 100 washes vehicles X parked in the car wash area G. The car wash machine 100 comprises a car wash machine body 1 and an underside cleaning device 2. The car wash machine body 1 mainly cleans the front, rear, both sides, and top of the vehicle, while the underside cleaning device 2 mainly cleans the underside of the vehicle. In Figure 1, to show the configuration of the underside cleaning device 2, only the external shape of the car wash machine body 1 is shown with a dashed-dot line. The general shape of the vehicle X parked in the car wash area G is also shown with a dashed-dot line.

[0011] Figure 2 is a schematic front view of the car wash machine 100. In Figure 2, a portion of the underside cleaning device 2, which will be described later, is shown as a dashed line that penetrates the ground. Figure 3 is a partial top view of the car wash machine 100, showing the spray from the pit cleaning unit. Figure 4 is a cross-sectional view taken along the line IV-IV in Figure 3. Figure 5 is a schematic diagram showing the configuration of the underside cleaning device 2.

[0012] (Car wash machine body 1) As shown in Figure 2, the car wash machine body 1 includes, for example, two frames 11 and a ceiling section 10 that connects the upper ends of the two frames 11. The car wash machine body 1 has a gate-like shape, as shown in Figure 1, which allows a vehicle X to pass through a space 1S enclosed by the frames 11 and the ceiling section 10 along the vehicle X's entry direction DA.

[0013] The car wash machine body 1 has, for example, wheels 12 at the bottom of each of the frames 11, and rotates these wheels 12 by a drive unit (not shown), thereby moving relative to the vehicle X in the longitudinal direction along rails R laid on the ground. The rails R are formed, for example, along the entry direction DA. While moving relative to the vehicle X, the car wash machine body 1 performs washing on the vehicle X in space 1S.

[0014] The car wash machine body 1 is equipped with multiple rotating brushes that slide and brush over the vehicle X as one of its washing sections. For example, the rotating brushes provided by the car wash machine body 1 include a top brush 14, a side brush 15, and a rocker brush 16, each rotated by a rotary motor (not shown). The top brush 14 moves along the top surface of the vehicle X and washes the top surface of the vehicle X. The side brush 15 and the rocker brush 16 wash both sides of the vehicle X. In particular, the rocker brush 16 is positioned below the side brush 15 and washes the lower side of the vehicle X.

[0015] Furthermore, the car wash machine body 1 is equipped with a blower 17 that generates airflow to dry the vehicle X. The blower 17 is connected to a top air blower nozzle 18 and side air blower nozzles 19 as air blowing nozzles. The top air blower nozzle 18 is located at the top center of the car wash machine body 1 and blows air toward the ceiling surface of the vehicle X. The side air blower nozzles 19 are located on both sides of the car wash machine body 1 and blow air toward the sides of the vehicle X. The car wash machine body 1 dries the vehicle X after washing by the air blowing from the top air blower nozzle 18 and the side air blower nozzles 19. The car wash machine body 1 may also blow air toward the underside of the vehicle X by adjusting the position and air blowing angle of each air blower nozzle to direct the air from each nozzle toward the underside of the vehicle X.

[0016] In each drawing of this specification, for the sake of simplicity of illustration, the illustration of each device for washing the vehicle X provided in the car wash machine main body 1 described above may be omitted. In addition, each device provided in the car wash machine main body 1 shown in FIG. 2 is merely an example, and the car wash machine main body 1 may include, in addition to the devices described above, devices for washing the vehicle X including conventionally known configurations and devices for assisting such washing on the frame 11 or the ceiling portion 10.

[0017] An operation panel 13 is arranged on the front surface of one frame 11 of the car wash machine main body 1. The operation panel 13 includes operation buttons (not shown) for setting car wash conditions, and accepts car wash or sets car wash conditions through operations by a user who has got off the vehicle X, a car wash staff, etc., and operates the car wash machine 100 for maintenance.

[0018] Furthermore, the car wash machine 100 may include a remote panel (not shown) for acquiring the car wash conditions of the vehicle X by the car wash machine main body 1 and the bottom surface washing device 2. The remote panel is located on the rear side of the car wash machine main body 1 and may be arranged approximately along the moving direction of the car wash machine main body 1.

[0019] Furthermore, the car wash machine 100 includes a control unit 50 for controlling the car wash machine main body 1 and the bottom surface washing device 2 described later. The control unit 50 controls the washing, drying, etc. of the vehicle X by the car wash machine main body 1 by controlling the movement of the car wash machine main body 1 along the rail R and the operations of each part of the car wash machine main body 1. Furthermore, the control unit 50 controls the washing of the bottom surface of the vehicle X by the bottom surface washing device 2 by controlling the operations of each part of the bottom surface washing device 2 described later.

[0020] As shown in FIG. 2, the control unit 50 may be provided in the car wash machine main body 1, or may be located outside the car wash machine main body 1. The control unit 50 may transmit and receive information to and from the car wash machine main body 1 or the remote panel by a communication device (not shown) and control the car wash machine main body 1 and the bottom surface washing device 2. The control unit 50 is composed of a processor such as a CPU, for example, and each control is realized by executing a control program stored in a memory on the processor.

[0021] (Lower cleaning device 2) The lower cleaning device 2 cleans the underside of the vehicle X. The lower cleaning device 2 includes, for example, a high-pressure pump unit 20, an injection unit 30, and a pipe 33 connecting the high-pressure pump unit 20 and the injection unit 30. The high-pressure pump unit 20 is an example of the pump unit according to the present disclosure. As shown in FIG. 5, the injection unit 30 includes a lower cleaning unit 31 that injects cleaning liquid toward the underside of the vehicle X and a pit cleaning unit 32 that cleans the inside of a storage pit described later. The pipe 33 connects the high-pressure pump unit 20 and the injection unit 30. More specifically, the pipe 33 connects the lower cleaning unit 31 of the injection unit 30 and the high-pressure pump unit 20. Also, the pipe 33 connects the pit cleaning unit 32 of the injection unit 30 and the high-pressure pump unit 20.

[0022] The high-pressure pump unit 20 is a device that pumps cleaning liquid to the lower cleaning unit 31 and the pit cleaning unit 32. As shown in FIG. 1, the high-pressure pump unit 20 may be arranged outside the car wash area G. The high-pressure pump unit 20 may have a high-pressure pump 21 and a solenoid valve unit 22. The solenoid valve unit 22 is a device that switches the flow path of the cleaning liquid from the high-pressure pump 21 between connections to the lower cleaning unit 31 and connections to the pit cleaning unit 32. By providing the solenoid valve unit 22, the cleaning liquid can be injected from either the lower cleaning unit 31 or the pit cleaning unit 32. As a result, it becomes difficult for the injection water pressure to decrease, enabling more effective lower surface cleaning and pit cleaning.

[0023] Before providing a detailed explanation of the spray unit 30 of the underbody cleaning device 2, we will first explain the groove structure provided on the ground within the car wash area. In the installation area of ​​the car wash machine 100 in the car wash area, the area sandwiched between the two rails R is called the car wash area G. The car wash area G is the area that receives the cleaning fluid used when washing the vehicle X by the car wash machine body 1 and the underbody cleaning device 2. In the central part of the width direction of the car wash area G, a central drainage groove 43 is provided to collect and drain the cleaning fluid (wastewater) containing sand, mud, etc. The central drainage groove 43 extends in the front-rear direction parallel to the rails R. A water collection section 45 may be provided at one end of the central drainage groove 43.

[0024] The water collection section 45 is a part that collects the cleaning fluid that has splashed onto the car wash area G, and may be, for example, a water collection basin. A protective member such as a grating may be placed on top of the water collection section 45. The cleaning fluid collected in the water collection section 45 can be discharged to the outside by any method. For example, a drain pipe may be connected to the bottom or side of the water collection section 45, and the cleaning fluid may be discharged to the outside through the drain pipe. In Figure 2, the water collection section 45 is located at the front end of the central drainage channel 43, but the water collection section 45 may also be located at the rear end.

[0025] As shown in Figure 2, the car wash area G may be sloped toward the central drainage channel 43 in order to improve the water collection efficiency to the central drainage channel 43. Also, the central drainage channel 43 may be sloped toward the water collection section 45 in order to improve the water collection efficiency to the water collection section 45.

[0026] The car wash area G is further provided with a storage section 40 for storing the piping 33 and the spray unit 30 located in the car wash area G. As shown in Figures 1 and 3, the storage section 40 has a storage pit 41 for storing the spray unit 30 and a piping storage section 42 for storing the piping 33.

[0027] The storage pit 41 is a groove for storing the injection unit 30 and extends in the front-rear direction on both sides of the central drainage groove 43. In a top view, the storage pit 41 is positioned to overlap with the vehicle X parked in the car wash area G during car washing. The storage pit 41 is equipped with multiple outlets 46 for discharging the cleaning fluid that flows into the storage pit 41 toward the central drainage groove 43. The outlets 46 and the central drainage groove 43 are connected by a water guide groove 44A. The water guide groove 44A is roughly perpendicular to the storage pit 41.

[0028] Figure 4 is a cross-sectional view taken along the line IV-IV in Figure 3. In Figure 4, for clarity, the position of the bottom surface of the storage section 40 when viewed through the cross section is indicated by a dashed line. As shown in Figure 4, the depth of the storage section 40 is shallower than the central drainage channel 43. As a result, the opening at the connection point between the water guide channel 44A and the central drainage channel 43 is located above the central drainage channel 43. The cleaning fluid that enters the central drainage channel 43 from the water guide channel 44A is collected in the water collection section 45 through the central drainage channel 43. As shown in Figure 3, a water guide channel 44B perpendicular to the storage pit 41 may also be provided on the outside of the storage pit 41, opposite the water guide channel 44A. The inflow of cleaning fluid from the water guide channel 44B makes it easier for the cleaning fluid containing dirt such as mud to flow out from the outlet 46 towards the central drainage channel 43.

[0029] The pipe storage section 42 has a groove shape and stores at least a portion of the pipe 33. The shape of the pipe storage section 42 in top view is not particularly limited as long as it has a structure that is continuous with the storage pit 41 and has a groove that extends beyond the lateral area of ​​the car wash area G. The pipe storage section 42 may be covered with a protective member 49 such as a grating or a steel plate. By covering the pipe storage section 42 with a protective member 49, the risk of damage to the pipe 33 when a vehicle X passes over the pipe 33 can be reduced.

[0030] (Bottom cleaning unit) The underside cleaning unit 31 sprays cleaning fluid onto the underside of the vehicle X. The underside cleaning device 2 has underside cleaning units 31, each of which is stored in one of the two storage pits 41. The underside cleaning device 2 may also have multiple underside cleaning units 31 in each storage pit 41. The multiple underside cleaning units 31 may be arranged in the front-rear direction within the storage pit 41. Figure 5 shows an example in which the spray unit 30 is equipped with three underside cleaning units 31 arranged in the front-rear direction within the storage pit 41.

[0031] Each underside cleaning unit 31 has an underside cleaning pipe 35 and one or more underside cleaning nozzles 34. The underside cleaning pipe 35 of each underside cleaning unit may be connected to a high-pressure pump unit 20 by a separate pipe 33. The underside cleaning nozzles 34 have their nozzles facing upward and spray cleaning fluid upward. This allows the underside of the vehicle X to be cleaned. The underside cleaning nozzles 34 may oscillate to clean the entire underside of the vehicle X.

[0032] The multiple underbody cleaning units 31 may operate independently of each other. For example, the control unit 50 may select one of the multiple underbody cleaning units 31 to perform the spraying operation according to the length of the vehicle X. Specifically, for example, if the length of the vehicle X is short, the cleaning fluid may be sprayed only from one or two underbody cleaning units 31 located at the front, and the remaining underbody cleaning units 31 may be stopped. By spraying the cleaning fluid from the underbody cleaning units 31 selected according to the length of the vehicle X, the amount of cleaning fluid used can be reduced, and the splashing of the cleaning fluid upwards can be reduced.

[0033] (Pit cleaning unit) The pit cleaning unit 32 cleans the inside of the storage pit 41. The bottom cleaning device 2 has a pit cleaning unit 32 housed in each of the two storage pits 41. The pit cleaning unit 32 comprises a pit cleaning pipe 37 and a plurality of pit cleaning nozzles 36. The pit cleaning nozzles 36 are attached to the pit cleaning pipe 37 so that the spray direction is directed towards the inside of the storage pit 41 or towards the inner surface of the storage pit 41.

[0034] In the bottom cleaning device 2, there may be only one pit cleaning unit 32 located within one storage pit 41. The pit cleaning pipe 37 may have a length close to the total length of each storage pit 41. This configuration allows for a reduction in the number of pipes within the storage section 40.

[0035] The number of pit cleaning nozzles 36 located within a single storage pit 41 may be less than the number of bottom cleaning nozzles 34. The cleaning fluid sprayed from the bottom cleaning unit 31 and the pit cleaning unit 32 is pumped by a high-pressure pump unit 20. In one embodiment, cleaning of the storage pit 41 by the pit cleaning unit 32 may be performed when bottom cleaning by the bottom cleaning unit 31 is not being performed. In this case, because the number of pit cleaning nozzles 36 is less than the number of bottom cleaning nozzles 34, the water pressure of the cleaning fluid sprayed from the pit cleaning nozzles 36 is higher than the water pressure of the cleaning fluid sprayed from the bottom cleaning nozzles 34. This makes cleaning inside the storage pit 41 more efficient.

[0036] Furthermore, as shown in Figure 5, at least some of the multiple pit cleaning nozzles 36 may be located between the multiple discharge ports 46. Also, at least some of the multiple pit cleaning nozzles 36 may spray cleaning fluid toward the discharge ports 46. In Figure 5, the area around the discharge ports 46, indicated by the dashed ellipses, is less prone to the accumulation of sediment such as mud due to the flow of cleaning fluid into the central drainage channel 43. On the other hand, the storage pits 41 located between the discharge ports 46 are more prone to the accumulation of mud and other debris.

[0037] By positioning the pit cleaning nozzles 36 in the storage pits 41 between the discharge ports 46, the cleaning liquid sprayed from the pit cleaning nozzles 36 can flow toward the discharge ports 46. Furthermore, by spraying the cleaning liquid toward the discharge ports 46, mud and other debris can be discharged from the discharge ports 46 more efficiently. For example, as shown in Figure 5, the pit cleaning nozzles 36 may be positioned on both sides of each discharge port 46, and configured so that the spray direction faces the discharge ports 46. By directing the spray direction of the pit cleaning nozzles 36 toward the discharge ports 46, mud and other debris can be discharged from the discharge ports 46 more efficiently.

[0038] The control unit 50 may perform cleaning of the storage pit 41 by the pit cleaning unit 32 while the vehicle is being washed, or it may perform cleaning when the vehicle is not being washed. By performing cleaning of the storage pit 41 by the pit cleaning unit 32 when the vehicle is not being washed, the distribution of cleaning fluid supplied from the high-pressure pump 21 becomes unnecessary, making it possible to clean the storage pit 41 at a higher pressure.

[0039] Furthermore, the control unit 50 may perform cleaning of the storage pit 41 by the pit cleaning unit 32 after the underside cleaning has been performed. When the underside of a vehicle is cleaned, the amount of sand, mud, etc. removed from the vehicle increases. By performing cleaning of the storage pit 41 after the underside cleaning has been performed, the accumulation of sand, mud, etc. in the storage pit 41 can be reduced.

[0040] Alternatively, the control unit 50 may be operated each time the vehicle X is washed, every few washes, or at any given interval. Even if the underside is not washed, the accumulation of sand, mud, etc., in the storage pit 41 can be reduced by regularly cleaning the storage pit 41.

[0041] Alternatively, the control unit 50 may perform cleaning of the storage pit 41 by operating the bottom cleaning unit 31 based on a cleaning instruction input by the operator via the operation panel 13 or the like.

[0042] The time it takes for the pit cleaning unit 32 to clean the storage pit 41 is determined appropriately based on factors such as the water pressure of the cleaning fluid and the cleaning frequency, but it may be around 30 to 60 seconds.

[0043] As described above, the car wash machine 100 according to Embodiment 1 is equipped with an underside cleaning device 2 for cleaning the underside of the vehicle X. The underside cleaning device 2 includes a high-pressure pump unit 20 and a spray unit 30 connected to the high-pressure pump unit and housed in a storage pit 41 provided on the ground. The spray unit 30 has an underside cleaning unit 31 that sprays cleaning liquid onto the underside of the vehicle X and a pit cleaning unit 32 that cleans the inside of the storage pit 41.

[0044] Mud and other debris that fall from vehicle X during car washing tend to accumulate in the storage pit 41. In particular, they accumulate on the bottom surface of the storage pit 41. By providing a pit cleaning unit 32 that can spray cleaning fluid into the interior of the storage pit 41, the inside of the storage pit 41 can be cleaned. This makes the cleaning work of the storage pit 41, which was conventionally performed manually by an operator, more efficient.

[0045] [Embodiment 2] Other embodiments of the present invention are described below. For the sake of clarity, components having the same function as those described in the above embodiments will be denoted by the same reference numerals, and their descriptions will not be repeated.

[0046] The car wash machine 100A according to Embodiment 2 comprises a car wash machine body 1 and an underside cleaning device 2A. The configuration of the underside cleaning device 2A in the car wash machine 100A according to Embodiment 2 differs from that of the underside cleaning device 2 in Embodiment 1. The other configurations are the same as those of the car wash machine 100 in Embodiment 1.

[0047] The following describes the bottom cleaning device 2A according to Embodiment 2 with reference to Figure 6. Figure 6 is a schematic diagram showing the configuration of the bottom cleaning device 2A. The bottom cleaning device 2A comprises a high-pressure pump unit 20, piping 33, and a spray unit 30A. The piping 33 connects the high-pressure pump unit 20 and the spray unit 30.

[0048] The injection unit 30A has a first pipe 35A and a plurality of injection nozzles 34A. The injection unit 30A is housed in a storage pit 41. The injection unit 30A may have at least one first pipe 35A for each storage pit 41. In this case, the first pipe 35A may have a length close to the total length of the storage pit 41. Alternatively, the injection unit 30A may have a plurality of first pipes 35A arranged in the front-rear direction.

[0049] The spray nozzle 34A is attached to the first pipe 35A and sprays cleaning fluid. The spray unit 30A may also include a rotating nozzle 36A as the spray nozzle 34A, which is rotatable in a rotational direction about the axis of the first pipe 35A.

[0050] The rotating nozzle 36A may be rotatable from vertically upward to vertically downward. The control unit 50 may control the rotating nozzle 36A so that its spray direction is upward when cleaning the underside of the vehicle X. The control unit 50 may also control the rotating nozzle 36A so that its spray direction is directed towards the inside or inner surface of the storage pit 41 when cleaning the inside of the storage pit 41.

[0051] By providing a rotating nozzle 36A that can spray cleaning fluid into the interior of the storage pit 41, the inside of the storage pit 41 can be cleaned. This makes the cleaning of the storage pit 41, which was previously performed manually by an operator, more efficient.

[0052] The injection unit 30A may include a fixed nozzle 38A as an injection nozzle 34A, whose injection direction is fixed upward. In other words, at least some of the multiple injection nozzles 34A may be fixed nozzles 38A with a fixed injection direction.

[0053] Any drive mechanism can be used for the rotating nozzle 36A, but the number of drive mechanisms can be reduced by limiting the number of rotating nozzles 36A. Including a fixed nozzle 38A in the injection nozzle 34A can reduce the cost associated with the drive mechanism.

[0054] If at least a portion of the injection nozzle 34A is a fixed nozzle 38A, the control unit 50 may inject cleaning fluid only from the rotating nozzle 36A when cleaning the storage pit 41. As a result, the water pressure of the cleaning fluid injected from the rotating nozzle 36A that cleans the storage pit 41 will be higher than the water pressure of the cleaning fluid when the entire injection nozzle 34A is used. Therefore, the storage pit 41 can be efficiently cleaned with high water pressure.

[0055] Furthermore, the control unit 50 may spray cleaning fluid from a plurality of injection nozzles 34A that are arbitrarily selected from among the plurality of injection nozzles 34A when cleaning the underside of the vehicle X and when cleaning the storage pit 41.

[0056] For example, the control unit 50 may appropriately select the spray nozzles 34A to be sprayed during underside cleaning according to the size of the vehicle. For example, if the length of the vehicle is shorter than the length of the spray unit 30, the cleaning fluid may be sprayed only from the spray nozzles 34A located at the bottom of the vehicle. This configuration can reduce the amount of cleaning fluid used and the amount of splashing.

[0057] The rotating nozzle 36A may be located between multiple discharge ports 46. For example, a nozzle located between two discharge ports 46 may be designated as the rotating nozzle 36A, and a nozzle located at another position (for example, a position overlapping with one of the discharge ports 46) may be designated as the fixed nozzle 38A. As described above, mud tends to accumulate in the storage pit 41 located between the two discharge ports 46. By arranging the rotating nozzle 36A, which can clean the inside of the storage pit 41, between the two discharge ports 46, the mud inside the storage pit 41 can be efficiently discharged, thereby improving cleaning efficiency.

[0058] The rotating nozzle 36A and the fixed nozzle 38A may either have their spray direction fixed when spraying the cleaning solution, or they may oscillate according to the cleaning area.
