Yes. The left and right ends are closed by a side plate portion 21D, and the duct hose 23 is connected to the upper plate portion 21A.

  The top nozzle 21 is lifted and lowered by a lifting means 31 provided on the car wash machine body 10 side. That is, as shown in FIGS. 4 to 8, an elevating drive shaft 32 along the vehicle width direction (left-right direction) B is rotatably provided on the upper portion of the car wash machine body 10. One end is wound around a forward / reverse drive unit 33 made of a motor or the like and is interlocked and connected via a transmission device 34. Transmission wheel bodies (such as sprockets) 35 are provided at both ends of the elevating drive shaft 32, and idler wheel bodies are disposed below the left and right vertical frame portions of the car wash machine body 10 so as to face the transmission wheel bodies 35. (A sprocket or the like) 36 is provided, and a rotating body (a chain or the like) 37 is provided between the ring bodies 35 and 36 opposed to each other in the vertical direction.

  The left and right vertical frame portions in the car wash machine main body 10 are provided with vertical guide bodies 38 respectively, and a pair of left and right lifting bodies guided by the guide bodies 38 via a guide roller 39 and a shake prevention roller 40. 41 is provided.

By rotating, the pair of left and right lifting bodies 41 can be moved up and down in synchronization with being guided by the guide body 38. Thereby, the top nozzle 21 can be moved up and down via the left and right rotating shafts 43, and thus the vertical position of the downward ejection port 21 a in the top nozzle 21 can be changed.

  Further, as shown by the phantom line in FIG. 8, the cylinder device 48 is extended by the control of the control device, so that the rotating shaft 43 can be rotated against the spring 47 with respect to the left and right lifting bodies 41, The direction (angle) of the top nozzle 21 can be changed. As shown by the solid lines in FIG. 7 and FIG. 8, the cylinder device 48 is contracted (or the extension pressure is released), so that the rotating shaft 43 is used with respect to the left and right lifting bodies 41 and the elastic force of the spring 47 is also used. Thus, it can be rotated in the reverse direction, and the top nozzle 21 can be returned downward. At this time, the downward posture of the top nozzle 21 can be regulated in a constant manner by the stopper body 45 coming into contact with the stopper body 46 by the elastic force of the spring 47 or the like.

  Prior to the drying action by the top nozzle 21, the wind is blown toward the upper surface 6 of the vehicle so that a water flow in the vehicle width direction B is generated. That is, as shown in FIGS. 1, 5, 6, and 9, the front and rear plate portions positioned on the upper side during the drying action (drying movement) in the top nozzle 21, that is, the rear side in the front-rear direction A A tubular nozzle 28 is branched from the front and rear plate portions 21C. Here, the tubular nozzles 28 are a pair (single or plural), branched from one end and the middle in the vehicle width direction B, and bent downward and to the other end, and the tip is directed to the other end. It is formed in the throttle outlet 28a which is laterally downward and has a small diameter. As a result, the drying air D supplied to the top nozzle 21 is branched into the tubular nozzle 28 and blown as an inclined wind (wind) C in the vehicle width direction B from the throttle outlet 28a toward the vehicle upper surface 6 side. Thus, the water flow E in the vehicle width direction B is generated.

  As shown in FIGS. 2 and 3, an operation panel 51 is provided on the front surface of the right vertical frame portion in the car wash machine body 10, and a control device 52 that controls the operation of each unit is provided on the back surface side of the operation panel 51. Is provided. A vehicle height sensor (not shown) is provided in the upper part of the car wash machine body 10. As shown in FIG. 10, the vehicle upper surface 6 has a bonnet portion 6a, a windshield portion 6b, a roof portion 6c, a rear glass portion 6d, and a trunk portion 6e in this order from the front to the rear. It is formed by that.

Hereinafter, the operation in the first embodiment will be described.
When performing the car wash, first, the driver or the operator operates the operation panel 51 in a state where the vehicle 5 to be cleaned is stopped, so that one desired car wash course (cleaning condition) is set. By turning on the car wash start switch in this state, the brush 18, 19, 20 spreads by rotation while the car wash machine body 10 reciprocates, and the water through the wash water nozzles 12, 14 is moved. Supply of (washing water), supply of diluted detergent through detergent nozzles 13, 16, supply of diluted water repellent coating agent through water repellent coating agent nozzle 15, dilution through wax nozzle 17 The desired basic cleaning process for the vehicle 5 to be cleaned is operated by appropriately combining the supply of wax and the ejection (blowing) of drying air (wind) D from the nozzles 21 and 22. And a drying process. When performing such a car washing process, the vehicle height, the vehicle length, and the like are detected by a vehicle height sensor and appropriate detection means, and the above-described operating units are preferably operated via the control device 52 and the like.

  In this way, the intended car wash can be performed. At that time, the top nozzle 21 is moved up and down by driving the forward / reverse drive unit 33 forward and backward by the control of the control device 52 based on the detection of the vehicle height sensor. By rotating the rotating body 37 forward and backward through the winding transmission device 34 and the lifting drive shaft 32, the left and right pair of lifting bodies 41 are moved up and down synchronously while being guided by the guide body 38. The rotation shaft 43 can be used. Further, changing the direction (angle) of the ejection port 21 a in the top nozzle 21 extends the cylinder device 48 under the control of the control device 52, and resists the rotating shaft 43 against the spring 47 against the left and right lifting bodies 41. It can be done by rotating it.

  As a result, as shown in FIGS. 9 and 10, the drying air (wind) D is ejected (sprayed) while the top nozzle 21 is moved up and down along the shape of the vehicle upper surface 6 of the vehicle 5 to be cleaned. Thus, a suitable drying operation without waste can be performed. At that time, the drying operation can be performed in a state where the top nozzle 21 is directed downward with respect to the roof portion (upper surface) 6c and the top nozzle 21 is changed to a suitable orientation (angle) with respect to the rear glass portion 6d and the like. It will be.

  In this way, when the drying operation is performed by blowing (spraying) the drying air (wind) D while moving the top nozzle 21, as shown in FIGS. 1, 9, and 10, the top nozzle The drying air D supplied to 21 is branched into a tubular nozzle 28 and blown as an inclined wind (wind) C in the vehicle width direction B from the throttle outlet 28a toward the vehicle upper surface 6 side. In this way, the water flow E in the vehicle width direction B is generated by blowing the inclined wind (wind) C toward the vehicle upper surface 6 side prior to the drying action by the top nozzle 21.

Therefore, for example, the groove 6M generated at the boundary between the hood 6a and the windshield 6b, the groove 6M generated at the boundary between the windshield 6b and the roof 6c, and the boundary between the roof 6c and the rear glass 6d. When cleaning water is accumulated in the groove 6M generated, the groove 6M generated at the boundary between the rear glass portion 6d and the trunk portion 6e, etc., the inclined wind (wind) C in the vehicle width direction B is blown onto these grooves 6M. Thus, a water flow E in the vehicle width direction B is generated in the groove 6M, and the cleaning water is blown sideways and discharged. As a result, before the drying operation is performed by blowing (spraying) the drying air (wind) D while moving the top nozzle 21 (in advance), the cleaning water accumulated in the groove 6M is blown sideways. Therefore, the air can be reliably discharged in the vehicle width direction B without being blown out to the periphery, and therefore, the subsequent drying action by the (following) top nozzle 21 is almost free of washing water in the groove 6M. This can be done without water being blown around and remaining on the upper surface 6 of the vehicle body.
[Embodiment 2]
Next, a second embodiment of the present invention will be described with reference to FIGS.

  One of the elevating bodies 41 includes an outer elevating part 41A provided with a guide roller 39 and a shake preventing roller 40, and an inner elevating part 41B provided with a rotating shaft 43 via a bearing 42. The elevating part 41A and the inner elevating part 41B are connected by a cylinder device 55. Therefore, the top nozzle 21 assumes a horizontal posture by lowering the inner lifting / lowering portion 41B by the contraction movement of the cylinder device 55, and assumes an inclined posture by raising the inner lifting / lowering portion 41B by the extension motion of the cylinder device 55. The top nozzle 21 is configured to be tiltable in the vehicle width direction B.

Hereinafter, the operation of the second embodiment will be described.
As shown by the solid line in FIG. 12, the top nozzle 21 blows drying air (wind) D through the ejection port 21a in a horizontal posture at a location not facing the groove 6M on the upper surface 6 of the vehicle. The drying operation is performed with a uniform air flow rate. And when it detects that the top nozzle 21 respond | corresponds to the groove part 6M by a suitable detection means, ie, in the location facing the groove part 6M in the vehicle upper surface 6, this top nozzle 21 is made into the virtual line of FIG. 11, FIG. As shown in the figure, an inclined posture is adopted, and drying air (wind) D is blown through the inclined outlet 21a. As a result, the balance of the blowing air volume in the vehicle width direction B is lost, and therefore, the water flow E in the vehicle width direction B is generated in the groove 6M, that is, the water flow E from the larger blowing air volume to the smaller one is generated. The washing water will be discharged to the side. Thereafter, as shown by the solid line in FIG. 12, the top nozzle 21 is returned to the horizontal posture, and the drying action is performed by blowing drying air (wind) D through the ejection port 21a.

  Thus, before the drying operation is performed by blowing (spraying) the drying air (wind) D while moving the top nozzle 21 (in advance), the washing water accumulated in the groove 6M is placed sideways. It can be discharged and reliably discharged in the vehicle width direction B without being blown out to the periphery. Therefore, since the subsequent drying action by the (subsequent) top nozzle 21 has almost no washing water accumulated in the groove 6M, The cleaning water can be discharged without being blown out to the periphery and remaining on the upper surface 6 of the vehicle body.

  In the first and second embodiments described above, a form is shown in which only the car wash machine main body 10 is moved to move the car wash machine main body 10 and the vehicle to be cleaned 5 relative to each other to wash the vehicle to be cleaned 5. However, this may be a type in which the car wash machine main body 10 is in a fixed state and the vehicle 5 to be cleaned is moved back and forth or one side using a roller conveyor (vehicle moving means) so as to move relative to each other. . Further, the car wash machine main body 10 may be divided into a front main body provided with a cleaning means and a rear main body provided with a drying means, and the front main body and the rear main body may be separately movable. Good.

  In the first and second embodiments described above, the drying air supplied to the top nozzle 21 is used to blow the winds C and D on the vehicle upper surface 6 side, but this is provided separately. Alternatively, the nozzle connected to the blower device may be arranged near the top nozzle 21. Moreover, the form etc. which branched from the duct hose 23 or the top side blower apparatus 24 may not be branched from the top nozzle 21.

  In the first embodiment described above, the form in which the inclined wind C is always blown from the tubular nozzle 28 is shown. This is because an electromagnetic valve or the like is incorporated in the tubular nozzle 28 and the groove portion 6M is supported by appropriate detection means. Only when it detects, the form etc. which opened the solenoid valve and sprayed the inclined wind C may be sufficient. In this case, closing of the solenoid valve is also automatically controlled.

  In the first embodiment, the top nozzle 21 is directed downward with respect to the roof portion (upper surface) 6c and the like, and the top nozzle 21 is changed to a suitable orientation (angle) with respect to the rear glass portion 6d and the like. Although a form for performing the drying operation is shown, a form in which the direction of the top nozzle 21 is fixed downward may be used.

In the second embodiment described above, the form in which the top nozzle 21 is inclined by the cylinder device 55 is shown, but this may be a drive cam form or a screw shaft form.
In the second embodiment described above, the cylinder device 55 is incorporated in one lifting body 41 and the top nozzle 21 is configured so as to be tiltable in the vehicle width direction B. It may be a built-in type in which these cylinder devices are alternately extended and tilted.
