  A vehicle detection unit 80 formed by a reflective photoelectric sensor or the like is provided at the lower end of the panel body 71. The vehicle detection unit 80 detects the to-be-cleaned vehicle CA stopped in front of the remote panel 7A.

  FIG. 4 is a block diagram showing the configuration of the car wash machine WA. The car wash WA includes a control unit 101 that controls each unit. A storage unit 102, an input / output unit 103, an operation unit 104, a car wash machine driving unit 105, and a rotation control unit 106 are connected to the control unit 101.

  The storage unit 102 includes a ROM and a RAM, and stores an operation program for the entire car wash machine WA, a car wash fee database, and the like, and temporarily stores calculations by the control unit 101. The input / output unit 103 communicates with the remote panel 7A. The car wash machine driving unit 105 drives each brush, each nozzle, and the like of the car wash machine body 1 based on the car wash conditions. The rotation control unit 106 varies the rotation speed of each brush driven by the car wash machine driving unit 105.

  FIG. 5 is a flowchart showing a process before the start of cleaning of the car wash machine WA. When the vehicle to be cleaned CA stops in front of the remote panel 7A, the processing is started by detection of the vehicle detection unit 80. In step S1, it waits until the setting of the washing condition of the vehicle CA to be cleaned is completed by the user's operation of the remote panel 7A or the operation panel 7.

  When the setting of the car wash conditions is completed, the process proceeds to step S2, and the outer shape detection of the vehicle CA to be cleaned is started by scanning of the outer shape detection unit 9. In step S3, it is determined whether or not the rotation speed of the top brush 4 is prohibited by the operation of the high speed washing button 113. If changing the rotational speed of the top brush 4 is prohibited, the process proceeds to step S6.

  If changing the rotational speed of the top brush 4 is not prohibited, it is determined in step S4 whether or not the degree of bending of the outer shape of the vehicle CA to be cleaned is smaller than a predetermined value. As will be described in detail later, the outer surface of the to-be-cleaned vehicle CA has bent portions K1 to K4 (see FIGS. 6 to 8), and the bending degrees are the angles θ1 to θ4 of the bent portions K1 to K4 (see FIG. 6). 6 to 8). If the degree of bending of the outer shape of the vehicle to be cleaned CA is greater than or equal to a predetermined value, the process proceeds to step S6.

  When the bending degree of the outer shape of the vehicle to be cleaned CA is smaller than a predetermined value, the process proceeds to step S5. In step S5, a predetermined range including the bent portion is stored as a low rotation period during which the rotation speed of the top brush 4 is reduced. In step S6, it is determined whether or not scanning of the vehicle CA to be cleaned by the outer shape detection unit 9 is completed. If the scan of the vehicle CA to be cleaned by the contour detection unit 9 has not been completed, steps S3 to S6 are repeated. When the scan of the vehicle CA to be cleaned by the outer shape detection unit 9 is finished, the cleaning of the vehicle CA to be cleaned is started in step S7.

  FIG. 6 is a side view showing a state when the vehicle to be cleaned CA is being washed. In the figure, TP1 indicates the locus of the rotating shaft 4A (see FIG. 7) of the top brush 4. The top brush 4 moves relative to the rear of the vehicle to be cleaned CA in the direction of the arrow D1 while moving up and down along the outer shape of the vehicle to be cleaned CA detected by the outer shape detector 9. At this time, the top brush 4 rotates downward (in the moving direction) as indicated by an arrow r1 (see FIG. 7).

  Further, when the top brush 4 passes through the vehicle to be cleaned CA, it moves relative to the front of the vehicle to be cleaned CA in the direction of the arrow D2. At this time, the top brush 4 rotates downward in the direction opposite to the arrow r1 (see FIG. 7) toward the front (moving direction). Thus, the car wash machine main body 1 including the top brush 4 is reciprocated with respect to the vehicle to be cleaned CA to perform car wash.

  At this time, a predetermined separation width d is formed between the center of the top brush 4 (rotating shaft 4A) and the outer surface of the vehicle to be cleaned CA, and the top brush 4 is relatively moved. There is a relationship of R> d between the radius R (see FIG. 7) of the top brush 4 and the separation width d. Thereby, the bristle 4B (see FIG. 7) of the top brush 4 slides on the outer surface of the vehicle CA to be cleaned.

  The outer surface of the vehicle to be cleaned CA is formed by a front surface M1, a bonnet M2, a windshield surface M3, a roof surface M4, a rear glass surface M5, and the like. A bent portion K1 whose outer shape is bent is formed at the boundary between the front surface M1 and the bonnet M2. A bent portion K2 whose outer shape is bent is formed at the boundary between the bonnet M2 and the windshield surface M3. A bent portion K3 whose outer shape is bent is formed at the boundary between the windshield surface M3 and the roof surface M4. A bent portion K4 whose outer shape is bent is formed at the boundary between the roof surface M4 and the rear glass surface M5.

  As shown in the figure, the front surface M1, the front glass surface M3, and the rear glass surface M5 of the vehicle CA to be cleaned are formed substantially vertically, and the hood M2 and the roof surface M4 are formed substantially horizontally. For this reason, the bending degrees θ1, θ3, and θ4 of the bent portions K1, K3, and K4 are small, and the angles are close to about 90 °. Further, the bending degree θ2 of the bent portion K2 is large and is an angle of 180 ° or more.

  FIG. 7 shows an enlarged side view of the bent portion K3. The top brush 4 relatively moves in the direction of the arrow D1 while rotating in the direction of the arrow r1 by driving a motor (not shown) connected to the rotating shaft 4A. As a result, the top brush 4 rotates in the downward direction toward the moving direction (D1), and is washed by applying a predetermined pressure to the outer surface.

  At the bent portion K3, the bending degree θ3 becomes a small angle close to 90 °. For this reason, the contact portion 4C at the tip collides with the windshield surface M3 substantially vertically at the same time in a state where the brush bristles 4B rotating at a predetermined position are substantially extended. For this reason, the area of the bristle 4B which collides simultaneously with the external surface of the to-be-cleaned vehicle CA becomes large. At this time, a low rotation period L13 is provided along the roof surface M4 in which the top brush 4 is decelerated and cleaned from outside the range during cleaning in a predetermined range including the bent portion K3.

  The low rotation period L13 is formed in the range of the radius R of the top brush 4 forward in the traveling direction from the position where the rotation shaft 4A of the top brush 4 is disposed substantially vertically above the bent portion K3.

  In the low rotation period L13, the rotation speed of the top brush 4 is set lower than that outside the low rotation period L13. For example, the rotation speed of the top brush 4 in the low rotation period L13 is 30 to 40 rpm, and the rotation speed of the top brush 4 outside the low rotation period L13 is 90 rpm. Thereby, even if the brush hair 4B collides with the windshield surface M3 of the to-be-cleaned vehicle CA substantially perpendicularly, it is possible to reduce noise due to the hitting sound of the brush hair 4B.

  Further, the relative speed of the top brush 4 is lower than that outside the low rotation period L13 within the low rotation period L13. For example, the moving speed of the top brush 4 in the low rotation period L13 is 2.5 to 3.5 m / min, and the moving speed of the top brush 4 outside the low rotation period L13 is 6 m / min. As a result, it is possible to prevent a decrease in cleaning ability due to a decrease in rotational speed.

  At this time, if the change of the rotation speed of the top brush 4 is prohibited by the operation of the high-speed washing button 113 (see FIG. 4), the car can be washed at high speed without decelerating the rotation speed and movement speed of the top brush 4. it can.

  Similarly, as shown in FIG. 6 described above, a low rotation period L11 is provided along the hood M2 for a predetermined range of cleaning including the bent portion K1. Thereby, the noise by the hitting sound of the bristle 4B which collides with the front surface M2 can be reduced.

  A low rotation period L14 is formed along the rear glass surface M5 for a predetermined range of cleaning including the bent portion K4. At this time, the top brush 4 descends substantially vertically on the rear glass surface M5. For this reason, the low rotation period L14 is formed in a range of the radius R of the top brush 4 forward in the traveling direction from the position where the rotation shaft 4A of the top brush 4 is arranged in the vicinity of the substantially horizontal direction of the bent portion K4. Thereby, the noise by the striking sound of the bristle 4B colliding with the roof surface M4 can be reduced.

  Similarly, when the top brush 4 moves in the direction of the arrow D2, a low rotation period L23 is formed along the windshield M3 for a predetermined range of cleaning including the bent portion K3. At this time, the top brush 4 descends on the windshield surface M3 substantially vertically. For this reason, it forms in the range of the radius R of the top brush 4 ahead of the advancing direction from the position which has arrange | positioned the rotating shaft 4A of the top brush 4 in the horizontal direction vicinity of the bending part K3. Thereby, the noise by the striking sound of the bristle 4B colliding with the roof surface M4 can be reduced.

  Further, a low rotation period L21 is formed along the front surface M1 for a predetermined range of cleaning including the bent portion K1. A low rotation period L24 is formed along the roof surface M4 for a predetermined range of cleaning including the bent portion K4. Thereby, the noise by the hitting sound of the bristle 4B colliding with the bonnet M2 or the rear glass surface M5 can be reduced.

  The low rotation periods L11, L13, L14, L21, L23, and L24 are set when the bending degree θ of the bent portion of the outer shape of the vehicle CA to be cleaned is smaller than 100 °, for example. In addition, when the bending degree θ, the radius R of the top brush 4, and the separation width d are in the relationship of sin θ> d / R, a contact portion 4 </ b> C that contacts perpendicularly to the outer surface is formed. For this reason, it is more desirable to provide a low rotation period when sin θ> d / R.

  FIG. 8 is a side view showing a state when another vehicle to be cleaned CA 'is washed. The outer surface of the to-be-cleaned vehicle CA 'has bent portions K1 to K4 that are bent in the same manner as the to-be-cleaned vehicle CA in FIG. The bending degrees θ1 to θ4 of the bent portions K1 to K4 are larger than a predetermined angle (for example, 100 °). For this reason, the low rotation period is not provided, and the top brush 4 rotates at a constant rotation speed and movement speed, and the vehicle to be cleaned CA 'is washed.

  According to this embodiment, when the bending degrees θ1 to θ4 of the bent portions K1 to K4 of the vehicle CA to be cleaned are smaller than a predetermined value, the predetermined range to be cleaned including the bent portions K1, K3, and K4 is set to the top brush 4. The low rotation periods L11, L13, L14, L21, L23, and L24 are reduced. Thereby, the noise by the hitting sound of the top brush 4 can be reduced, and a user's discomfort and fear can be reduced.

  In addition, the relative speed between the vehicle CA to be cleaned and the car wash machine body 1 in the low rotation periods L11, L13, L14, L21, L23, and L24 is lower than outside the low rotation periods L11, L13, L14, L21, L23, and L24. Therefore, it is possible to prevent the cleaning power from being reduced due to the reduction in the rotational speed of the top brush 4.

  Further, when the radius of the top brush 4 is R, the separation width between the rotating shaft 4A of the top brush 4 and the outer surface of the vehicle CA to be cleaned is d, the bending degree is θ, and a low rotation period is provided when sin θ> d / R. Therefore, the region where the brush bristles 4B are in contact with the outer surface of the vehicle CA to be cleaned perpendicularly can be reliably set to the low rotation period.

  Further, the top brush 4 rotates downward in the moving direction, and the low rotation period is a predetermined length ahead of the top brush 4 in the moving direction from the position where the rotating shaft 4A is arranged in the vicinity of the bent portion vertically above or horizontally. It is in range. Thereby, the low rotation period can be reliably started at a position where the bristles 4B collide with the vicinity of the bent portion.

  Further, since the length of the low rotation period is set to be approximately the radius of the top brush 4, the low rotation period can be reliably ended at a position where the brush bristles 4B are separated from the vicinity of the bent portion.

  In the present embodiment, the front surface M1 and the bonnet M2 are separated from the interior of the vehicle to be cleaned CA. A cushion material is usually laid on the indoor side of the roof surface M4. Thereby, it is difficult for the hitting sound of the top brush 4 to reach the front surface M1, the bonnet M2, and the roof surface M4. On the other hand, since the front glass surface M3 and the rear glass surface M5 are covered with thin glass, the hitting sound of the top brush 4 easily reaches the room. For this reason, at least low rotation periods L13 and L24 in which the brush bristles 4B collide with the front glass surface M3 or the rear glass surface M5 substantially vertically may be provided, and a part or all of the other low rotation periods may be omitted.

  In addition, the rotation speed of the top brush 4 during the low-speed rotation period and the threshold value of the degree of bending for providing the low-speed rotation area may be set by the operation unit 104.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the car wash machine which installs in a gas station etc. and wash | cleans a to-be-washed vehicle.
