Description

  The present invention provides a car wash machine for cleaning and drying a car body of a car by reciprocating a car wash body formed in a gate shape so as to straddle the car, so that the car can be reliably dried even under night conditions. It is a thing.

  Body drying used in this type of car wash machine has been mainly air blowing drying in which high-pressure air generated by a blower is applied to the body to blow off water droplets remaining on the surface of the body. This blow drying has a problem that since the noise of the blower is large, use at night is often restricted in residential areas and the like, and the car cannot be washed substantially. Until now, measures such as reducing the output of the blower by using an inverter to reduce noise have been taken, but the decline in drying performance cannot be denied, and satisfactory car body drying has not been achieved.

In order to solve this problem, Japanese Patent Laid-Open No. 2001-301585 has been proposed. This invention removes water droplets scattered on the vehicle body by applying water in a laminar flow to the vehicle body after washing, and realizes vehicle body drying close to silence without using a blower. Yes. However, in such running water drying, a sufficient water-drawing action can be obtained at the inclined part (glass surface, etc.) of the vehicle body, but at the flat part (bonnet, roof, trunk, etc.), the action is weak and water drops tend to remain. there were. In addition, since the drying process performed in a general car wash machine is executed on the return path that runs from the rear end to the front end of the automobile, when drying a sedan type automobile, running water is dried on the rear glass surface. The running water that had flowed down the glass surface wetted the trunk after it was dried. Furthermore, since the flowing water that protrudes from the width of the automobile falls directly to the floor surface, there is a problem that water droplets that bounce off the floor surface adhere to the lower part of the vehicle body.

As the drying system, an upper surface blowing nozzle 5 that blows high pressure air on the upper surface of the vehicle body to remove water droplets on the vehicle body, a pair of left and right side air blowing nozzles 6 and 6 that blow high pressure air on the side surfaces of the vehicle body to remove water droplets on the vehicle body, A running water drying device 7 is provided for supplying running water to the upper surface of the vehicle body and removing water droplets from the vehicle body by a water-drawing action. Here, the upper surface blowing nozzle 5 is arranged on the front side with respect to the traveling direction of the main body 1, and the running water drying device 7 is arranged behind this. As the detection system, a vehicle shape detection device 8 that is provided in front of the car wash machine main body 1 and reads a shape (silhouette) from the side of the automobile as the main body 1 travels, motors 9 and 9 that cause the main body 1 to travel, Encoders 10 and 10 are provided which are attached to the output shafts of the motors 9 and 9 and output pulses each time the main body 1 travels a unit distance.

Next, the configuration of the drying system that is a characteristic configuration of the present invention will be described. FIG. 3 is an explanatory view showing the upper surface blowing nozzle 5 of the first embodiment.
The upper surface blowing nozzle 5 is mounted on the upper left and right sides of the main body 1 one by one and is connected to the blowers 11 and 11 that can change the rotation speed by inverter control via the ducts 12 and 12 and ejects high-pressure air. The device 13 is provided so as to be movable up and down along the shape of the upper surface of the automobile.

  The lifting device 13 for the upper surface blowing nozzle 5 includes carriages 15 and 15 attached to the ends of arms 14 and 14 extending horizontally from the left and right side surfaces of the nozzle 5, and guide rails 16 and 16 suspended from the inner side of the main body 1. A rotating shaft 17 installed horizontally on the upper portion of the main body 1, upper sprockets 18a and 19a attached to the rotating shaft 17, and a lower portion provided at the lower portion of the main body 1 to form a pair with the upper sprockets 18a and 19a. The sprockets 18b and 19b, the chains 20 and 20 suspended between the upper and lower sprockets and linked to the upper and lower ends of the carriages 15 and 15 respectively, the motor 21 for driving the rotary shaft 17, and one end of the rotary shaft 17 are connected. The encoder 22 is configured to output a pulse every time it travels a unit distance while detecting the rotation direction of the rotary shaft 17. Thereby, when the motor 21 is rotated forward, the nozzle 5 rises along the guide rails 16 and 16, and when the motor 21 is rotated reversely, the nozzle 5 moves downward.

FIG. 4 is an explanatory view showing the running water drying apparatus 7 of the first embodiment.
The running water drying device 7 has a running water supply member 23 formed wider than the width of a car that can be washed, and the running water supply member 23 is disposed at substantially equal intervals to spill water flow down directly below the water rod-like running water. A plurality of flowing nozzles 24 to be formed, and a submersible pump 27 for supplying water from a water storage tank outside the main body 1 to each flowing nozzle 24 through a pipe 25 and an electromagnetic valve 26. Similarly, the lifting device 28 is provided so as to be lifted and lowered along the shape of the upper surface of the automobile.

  The elevating device 28 of the running water drying device 7 includes carts 30, 30 attached to the tips of arms 29, 29 extending horizontally from the left and right side surfaces of the running water supply member 23, and a guide rail 31 suspended from the inner side of the main body 1. , 31, a rotating shaft 32 installed horizontally on the upper portion of the main body 1, upper sprockets 33 a and 34 a attached to the rotating shaft 32, and a lower portion of the main body 1 so as to form a pair with the upper sprockets 33 a and 34 a. Lower sprockets 33b, 34b, chains 35, 35 suspended between the upper and lower sprockets and linked to the upper and lower ends of the carriages 30, 30, respectively, a motor 36 for driving the rotary shaft 32, and one end of the rotary shaft 32 And an encoder 37 that outputs a pulse each time it travels a unit distance while detecting the rotation direction of the rotary shaft 32. As a result, when the motor 36 is rotated forward, the flowing water supply member 23 rises along the guide rails 31, 31, and when the motor 36 is reversed, the flowing water supply member 23 is moved downward. At this time, as described above, the elevation control is performed so as to keep the distance L between the flowing water nozzle and the vehicle body surface constant.

As shown in FIG. 5, drying by the flowing water drying device 7 is performed by naturally dropping water rod-shaped flowing water from the flowing water nozzles 24. When a water rod-shaped flowing water is naturally dropped from a height that does not jump up on the vehicle body surface, it spreads in a ripple shape on the surface of the vehicle body in contact, forming a water film, and each adjacent rippled water film leads to the entire vehicle width As a result, the water flows down uniformly according to the inclination of the vehicle body surface. At this time, since it flows down with the water droplets remaining on the vehicle surface, the residual droplets are removed and the vehicle surface is dried. For this reason, it is important to set the distance L between the flowing water nozzle 24 and the vehicle body surface, the number N of flowing water nozzles, the interval S between the nozzles, the diameter k of the flowing water nozzle, and the flow rate Q from the flowing water nozzle. In this regard, according to the experiment by the present applicant, the optimum conditions could be obtained by the following numerical values.
(Distance L = 200 mm, number of nozzles n = 10, nozzle interval p = 200 mm, nozzle diameter φ = 12 mm, flow rate Q = 60 l / min)

Next, the control system of the present invention will be described. FIG. 6 is a block diagram illustrating the control system of the first embodiment.
Reference numeral 40 denotes a car wash control unit which takes in the vehicle upper surface position data from the vehicle shape detection device 8 using a pulse signal output from the encoder every time the main body 1 travels a unit distance as a trigger, and uses the vehicle body upper surface position data as a unit of the main body 1. The washing system (3, 4, 4) and the drying system (5, 6, 6, 7) of the car washing apparatus are operated along the shape (silhouette) of the upper surface of the automobile that is accumulated and formed every distance traveled. Car wash according to the position, shape, equipment, etc. Reference numeral 41 denotes an inverter for changing the frequency of the blower, which has an ability to attenuate the frequency in a stepwise manner to −15 Hz, and is used in order to reduce the noise when the blower is used at night. Here, when the frequency is lowered by 10 Hz, the noise is reduced to about 6 dB.

  Reference numeral 42 denotes an operation unit, a course selection key 43 for selecting a car wash course, a display panel 44 for guiding and displaying a car wash fee, an operation procedure, and the like to a person who operates, a start key 45 for inputting start of car wash, and a normal car wash In addition to a key switch 46 for switching between a mode and a management mode for inspection and setting by an administrator, a key for manually selecting the form of the drying process, which is also a feature of the present invention, is provided. The drying selection key includes a combination key 47 that selects a drying process that uses both blowing drying by the top blowing nozzle 5 and flowing water drying by the flowing water drying device 7, and flowing water that selects a drying process only by flowing water drying by the flowing water drying device 7. When these drying selection keys are input, the drying process in the car washing course selected by the course selection key 43 is executed with the contents. In addition, when the form of a drying process is not selected and a course is selected, the drying process by ventilation drying is performed similarly to a general car wash.

  In the management mode, it is possible to perform management work such as counting and abnormality inspection and setting work such as business hours and working days. In this setting work, it is also possible to set the drying mode in each time zone (nighttime, early morning, etc.) during business hours. When the set time zone is reached, the key operation with the drying selection key becomes invalid and automatic. The drying process is executed in a dry form set automatically.

Subsequently, the operation of the first embodiment will be described.
After the automobile A is stopped at an appropriate car wash position, the car wash machine body 1 is run, the brush process for controlling the washing system in accordance with the car body shape read by the car shape detection device 8 and brushing the car body surface, and the car wash machine A drying process of running and controlling the drying system in accordance with the shape of the vehicle body to dry the surface of the vehicle body is executed in combination according to the car wash contents. Here, the case where “2 reciprocating wax-combined drying” is set as the car wash course will be described based on the flowchart of FIG.

  First, as the main body 1 travels, the most advanced vehicle shape detection device 8 takes in the upper surface position data of the automobile to be cleaned every time the main body 1 travels a unit distance, and creates vehicle shape data (1). At the same time, the upper surface brush 3 and the side surface brushes 4 and 4 are driven while spraying the cleaning water from a watering nozzle (not shown), and the upper surface cleaning brush 3 and the side surface cleaning brushes 4 and 4 are mounted on the vehicle body according to the upper surface position data detected previously. The vehicle body surface is preliminarily cleaned (2).

  When the main body 1 moves back, this time, the upper surface cleaning brush 3 and the side surface cleaning brushes 4 and 4 are driven while spraying the detergent water diluted to a predetermined concentration from the watering nozzle, and the upper surface position data previously detected. The shampoo cleaning of the vehicle body surface is performed (3).

  When the main body 1 shifts to the second forward, this time, the upper surface cleaning brush 3 and the side surface cleaning brushes 4 and 4 are driven while spraying wax water from the watering nozzle, and the vehicle body conforms to the previously detected upper surface position data. The vehicle body surface is cleaned with wax (4). At this time, brushing is performed with a soft contact pressure by reducing the number of rotations of each brush as compared with preliminary cleaning and shampoo cleaning.

  When the main body 1 shifts to the second retrograde, air blowing drying by driving the upper air blowing nozzle 5 and the side air blowing nozzles 6 and 6 and running water drying by driving the running water drying device 7 are executed simultaneously (5). . When the main body 1 goes backward, the running water drying device 7 runs forward from the rear of the automobile while leading, and thus the vehicle body is subjected to running water drying and blowing drying in order. In addition, since the combined drying that performs running water drying and air blowing drying is basically set as a noise countermeasure in the early morning and night, the blowers 11 and 11 have a frequency of about 20% that of normal use by inverter control. It is used in the state which dropped. Thereby, noise reduction is achieved and the flowing water from the flowing water drying device 7 is also prevented from being blown by the blowing from the upper surface blowing nozzle 5.

FIG. 8 is an explanatory view showing the operation in the drying process.
As shown in FIG. 8A, the preceding running water drying device 7 is controlled to move up and down while maintaining the distance L from the vehicle body based on the detected upper surface position data. By maintaining this distance L, the water rod-shaped running water from the running water nozzle 24 comes into contact with the vehicle body surface and spreads into a water film shape, and the adjacent water films are connected to each other to incline the vehicle body surface. It starts to flow down to match.

  By the way, in a portion where the inclination of the vehicle body is small (trunk portion T, roof portion R, bonnet portion B, etc.), water hardly flows down and water droplets are likely to remain. In particular, when running water is applied to the rear glass rG or the rear of the roof portion R (thick line portion), the water flows down to the trunk portion T after drying. With respect to such water droplets, air blown from the upper surface blower nozzle 5 following the running water drying device 7 acts, and slightly remaining water droplets are blown away. As shown in FIG. 8B, the upper surface blowing nozzle 5 is made to approach the vehicle body in accordance with the detected upper surface position data. Here, in the range from the trunk portion T to the roof portion R of the automobile A, the upper surface blowing nozzle 5 is directed in the direction opposite to the backward direction of the main body 1 so as to minimize the influence on the running water drying device 7. Is desirable.

  In this case, the car wash machine illustrated here is a type in which the main body travels in a reciprocating unit to back the car after the car wash, but the drive-through disclosed by the present applicant in Japanese Patent Laid-Open No. 10-138880 is disclosed. It can also be used in a type of car wash. In this case, the positional relationship between the upper surface blowing nozzle and the upper surface water supply device is reversed, and the drying process is executed as the car wash machine travels.

FIG. 9 is an explanatory view showing a running water drying apparatus according to the second embodiment.
The running water drying device 50 here is similar to the first embodiment described above, and the running water supply member 51 formed wider than the width of the car that can be washed and the running water supply member 51 are arranged at almost equal intervals. A plurality of water nozzles 52 that form water rod-like water flowing down directly below, a submersible pump 53 that supplies water to the water nozzle from a water storage tank T outside the main body, and a pipe 54 that communicates the pump and the nozzle, A lifting device (not shown) can be moved up and down along the shape of the upper surface of the automobile. Dedicated branch pipes 54a and 54b are assigned to the flowing water nozzles 52a and 52b located at both ends, and electromagnetic lines are respectively provided to the pipes. A configuration including valves 56 and 57 is added.

  As a detection system equipped in the car wash machine main body 1, a side detection device 58 for detecting the side position and shape of the automobile is added. The side surface detection device 58 transmits ultrasonic waves from the side of the automobile toward the side surface of the vehicle body, and detects the side surface position of the vehicle body by rebounding from the side surface data. Car body side shape data is created by taking Incidentally, as described in Japanese Patent Application Laid-Open No. 11-342835 filed earlier by the present applicant, the side detection device emits light from the upper side of the main body 1 and reflects it from the surface of the vehicle body. The shape of the side surface of the vehicle is detected together with the travel position of the main body 1 based on the position of the vehicle body side surface received and the brush position when the side surface cleaning brush is brought into contact with the side surface of the vehicle body with a predetermined contact pressure. Things can be used.

  According to such a configuration, during the drying process using the running water drying apparatus 50, the elevation control along the vehicle body upper surface shape and the running water control along the vehicle body side shape are performed. Of these, the running water control is for determining whether or not to run water from the running nozzles 52a and 52b at both ends of the running nozzles 52 provided in the left-right direction, and the vehicle width is narrow as in a light car. Control is performed such that both water is not discharged to the automobile, and only one water discharge is performed on the automobile that is biased to the car wash position. That is, when it is determined from the detected side surface shape of the vehicle body that the water discharged from the flowing water nozzle located at the end does not hit the vehicle body, the water flowing from the flowing water nozzle is not performed. As a result, it is possible to prevent the flowing water that has fallen directly on the floor without hitting the vehicle body from jumping up and getting wet on the lower part of the side surface of the vehicle body.

FIG. 10 is an explanatory view showing a running water drying apparatus according to the third embodiment.
The running water drying device 60 here has a frame 61 formed wider than the width of a car that can be washed, and a width that is narrower than the width of a car that can be slid in the left-right direction within the frame. A flowing water supply member 62 formed in a width, a plurality of flowing nozzles 63 disposed at substantially equal intervals on the flowing water supply member 62, a submersible pump 64 for supplying water to the flowing nozzle from a water storage tank T outside the main body, and a pump And a pipe 65 that communicates with the nozzle, and is provided so that it can be raised and lowered along the shape of the upper surface of the automobile by a lifting device (not shown). A sliding device 66 that slides the running water supply member 62 in the left-right direction within the frame 61 is provided. It is provided.

  The slide device 66 is attached to the frame 61 horizontally and the guide rail 67 on which the flowing water supply member 62 travels, the left and right sprockets 68a and 68b, and the chain that is suspended between the sprockets and the tip is linked to the flowing water supply member 62. 69, a motor 70 that rotates the right sprocket 68a, and an encoder 71 that is connected to the output shaft of the motor 70 and outputs a pulse each time it rotates by a unit angle.

  According to such a configuration, the flowing water supply member 62 can be slid so as to be positioned on the upper surface of the vehicle body in accordance with the detected vehicle body side surface position, and the automobile is stopped obliquely with respect to the stop position. Even if it is a case, it can dry by flowing water, without the flowing water from a flowing water nozzle dropping on a floor surface. Thereby, it can prevent that the flowing water which fell directly on the floor surface, without hitting a vehicle body, jumps up and wets the lower part of the vehicle body side surface.

  It applies to car wash machines installed in places where there are regulations or complaints regarding noise, such as residential areas.
