  By the way, according to a conventional car wash machine, generally, a pre-cleaning spray nozzle, a detergent spray nozzle, a cleaning spray nozzle for washing away the detergent, and a finishing agent spray nozzle for spraying wax are provided.

  However, for example, in the case of a car wash course in which all the washing operations are performed in one trip, each washing operation is short in time, so if washing and waxing are surely performed, the washing water is of course In addition, a large amount of wax is also injected. For example, after the preliminary cleaning, the cleaning operation with the detergent, and the cleaning operation with the cleaning water, the final cleaning with the wax is performed, and the wax sprayed by the final cleaning is flushed with a large amount of the cleaning water immediately before the cleaning operation. Therefore, it was necessary to use a large amount even in the waxing operation.

  Then, an object of this invention is to provide the car wash method and car wash machine which can save the usage-amount of wax.

In order to solve the above problems, the car wash method of the present invention is a mixture of washing water and wax when jetting washing water and washing the detergent after spraying the detergent on the vehicle that has been pre-washed. liquid and by injection range in the long line shape in the longitudinal direction of the vehicle is injected at high pressure with rocking in the lateral direction of the vehicle, Ru method der for cleaning and the waxing simultaneously.

Further, the car wash machine of the present invention has at least a pre-cleaning injection nozzle for pre-cleaning the main body frame formed in a gate shape by injecting cleaning water onto the vehicle, and a detergent for injecting the detergent onto the vehicle after the pre-cleaning In a car wash machine having a spray nozzle for cleaning and a spray nozzle for finishing cleaning that sprays a mixture of cleaning water and wax onto a vehicle on which a detergent is sprayed,
A car wash machine characterized in that an injection range of the mixed liquid is formed in a line shape long in the vehicle front-rear direction and is injected at a high pressure while swinging in the vehicle left-right direction .

According to the configuration of the car wash method and the car wash machine, for example, when the car wash course is short, a large amount of wash water is used, and in the waxing operation performed immediately after the wash operation, wax is also contained in the wash water. In consideration of being washed away, a large amount of wax will be supplied, but by mixing the wax with the high-pressure jet of washing water that is finally performed, the wax is jetted simultaneously with the washing, At the same time as the removal of dirt, the wax can be firmly attached, so that waxing can be performed with a small amount of water and the amount of wax used can be saved.
Furthermore, by spraying the liquid mixture of water and wax while oscillating left and right with a linear spray range, the wax is blown farther and the pre-brushed sewage is pushed out of the vehicle Therefore, it can be washed with a small amount of water and a small amount of wax is sufficient.

  In the present embodiment, as described above, the three injection devices 21 to 23 are described for liquid injection, and in particular, the finish cleaning injection device 23 that is the gist of the present invention will be described in detail. In practice, a preliminary detergent spraying device for spraying a preliminary detergent instead of preliminary cleaning water, a water repellent spraying device for spraying a water repellent, and the like are provided as necessary.

  Although not shown, the rear main body 3 has a top nozzle that is movable in the vertical direction, i.e., can be moved up and down, and dries the upper surface of the vehicle by injecting air. A pair of left and right side nozzles that are movable, that is, traversable to dry both side surfaces of the vehicle, and a pair of left and right blower devices that supply air to the two nozzles via, for example, a communication duct are provided. .

  By the way, the gist of the present invention resides in the finishing cleaning spraying device 23 for spraying the cleaning water and the wax for finishing provided in the post-process among the liquid spraying devices as described above. Description will be made by paying attention to the device 23 and the liquid supply device 24.

  As shown in FIGS. 3 to 5, the finish cleaning spray device 23 is a windshield projecting rearwardly from the front body 2 on the horizontal portion 2 a side of the front body 2 that is a portal frame. The support frame member 31 mounted in the horizontal direction near the rear of the horizontal frame member 2d of the portion 2c and in the horizontal direction, and the front and rear direction of the support frame member 31 at the left and right positions via the bearings 32 respectively. Rotating support type elbow joint (joint member, which is an example of a horizontal support shaft) 33 provided so as to be rotatable around a horizontal axis, and a swing having one end connected to the upper part of each elbow joint 33 The lever 34 (34A, 34B), the first connecting rod 35 that is a connecting member that connects the other ends of the swing levers 34A, 34B on the left and right sides, and the center of the support frame member 31 are provided. electric 36, a rotating lever 37 attached to the output shaft 36a of the electric motor 36, and a connecting member that connects the tip end portion (free end portion) of the rotating lever 37 and the other end portion of the one swing lever 34A. A second connecting rod 38 and a finish cleaning injection nozzle 39 connected to a lower connection port 33a which is one end side of each elbow joint 33 are configured. In addition, as each said injection | spray nozzle, what the injection range becomes a cone shape is used. Further, the shaft portion 33c of the elbow joint 33 supported by the bearing 32 corresponds to a horizontal support shaft, and the rotation lever 37 and the electric motor 36 constitute a swing drive device.

Next, the liquid supply device 24 that supplies cleaning liquid such as cleaning water, detergent, wax, etc. to each spray nozzle will be described.
As shown in FIG. 6, the liquid supply device 24 is disposed in the water tank 41, a water tank 41 for storing cleaning water, a detergent tank 42 for storing detergent, a wax tank 43 for storing wax, and the water tank 41. A submersible pump 44, a high-pressure pump 45 that is provided in the middle of a first water pipe to be described later, pressurizes water from the submersible pump 44 to supply high-pressure water, and a first electromagnetic on-off valve 51 is provided in the middle. A first water pipe 52 for supplying high-pressure water from the high-pressure pump 45 to the preliminary-cleaning injection nozzle 21a, and a second electromagnetic on-off valve 53 and a first injector 54 are provided on the way, and low-pressure water ( A second water pipe 55 for supplying a header pipe (also referred to as an arch) 22b having a detergent injection nozzle 22a (in the sense that it is lower than high-pressure water). A detergent supply pipe 57 provided with a valve 56 and having one end connected to the detergent tank 42 and the other end connected to the first injector 54, and a fourth electromagnetic on-off valve 58 and a second injector 59 in the middle. And a third water pipe 60 for supplying high-pressure water from the high-pressure pump 45 to the finishing cleaning spray nozzle 39, a fifth electromagnetic on-off valve 61 in the middle, and one end connected to the wax tank 43. And the other end portion is constituted by a wax supply pipe 62 connected to the third injector 59. The base end of the first water pipe 52 is connected to the submersible pump 44, and the base end of the second water pipe 55 is connected to the middle of the first water pipe 52 on the upstream side of the high-pressure pump 45. The three water pipe 60 is branched from the middle of the first water pipe 52.

  The preliminary cleaning spray nozzle 21a is also swung left and right by an electric motor through a swing drive mechanism (consisting of a swing lever, connecting rods, a rotating lever, etc.) similar to the finish cleaning spray nozzle 23. Is configured to do.

  The high-pressure pump 45 supplies high-pressure water to the pre-cleaning spray nozzle 21a, and the vehicle is pre-cleaned. Further, when the water supplied from the submersible pump 44 flows through the second water pipe 55, the detergent is sucked from the detergent tank 42 through the first injector 54, and the detergent diluted with water is jetted onto the vehicle. . Furthermore, when the high-pressure water supplied from the high-pressure pump 45 flows through the third water pipe 60, the wax is sucked from the wax tank 43 via the second injector 59, and the wax diluted with water is the high-pressure washing water. At the same time, it is injected into the vehicle. Of course, the pre-cleaning spray nozzle 21a and the finish cleaning spray nozzle 39 for spraying high-pressure water are swung left and right by the electric motor 36, respectively.

  In the above configuration, when the vehicle C is washed, after the vehicle C is stopped at a predetermined position, the car washer main body 1, that is, the front main body 2 and the rear main body 3 are moved to the vehicle C side. Preliminary cleaning is performed by spraying cleaning water onto the vehicle C from the preliminary cleaning injection nozzle 21a of the preliminary cleaning injection device 21 provided at the front of the vehicle. Next, the detergent diluted with water is sprayed from the detergent spray nozzle 22a of the detergent spray device 22 onto the vehicle C, and the vehicle is cleaned by the brushing means.

  After this cleaning, the finishing cleaning water is sprayed together with the wax from the finishing cleaning spray nozzle 39 of the finishing cleaning spraying device 23 provided at the rear of the front body 2 so that the wax is quickly Coating without waste. In addition, although it demonstrated that brushing was performed at the time of jetting of a detergent, of course, the brushing means is act | operated when required in another washing | cleaning process.

  Then, after the front body 2 has been brushed, cleaned and finished, the rear body 3 continues to blow air from the drying nozzles onto the vehicle C for drying.

  According to the above configuration, the wax is mixed when the finishing cleaning water is jetted at a high pressure in the subsequent step of the cleaning operation in the vehicle, that is, the wax is swung left and right on the surface of the vehicle together with the high pressure water. In this case, the wax can be coated on the surface of the vehicle with a small amount of liquid.

  More specifically, in a conventional car wash machine, when a car wash course with a short car wash time is selected (for example, when car wash is performed on one way), a large amount of wash water is used and immediately after the washing process. Also in the waxing process, the wax is supplied more than necessary in consideration of the fact that the wax is poured into the washing water jetted in large quantities, but at the end like the car wash machine of the present embodiment, By mixing the wax with the high-pressure jet of washing water to be performed, the wax is also jetted at the same time as the high-pressure washing, so that the wax can be surely adhered to the vehicle surface at the same time as removing the dirt, and thus washing with a small amount of water And the amount of wax used can be saved.

  By the way, as an injection nozzle, it has been described that an injection range having a conical shape is used, but among them, particularly as an injection nozzle 39 for finishing cleaning, an injection region is narrowed [the injection region is a point, That is, the injection range may be substantially linear (more accurately, it can be said that the apex angle is a very small cone). In this way, by spraying the linear cleaning liquid with high pressure while swinging left and right, the wax is blown farther, and the action of pushing the sewage that has been brushed in advance to the outside of the vehicle arises. It can be washed with a small amount of water and a small amount of wax.

Moreover, in the said embodiment, although the car wash machine main body demonstrated the case where it was a separation | separation form of a front part main body and a rear part main body, of course, it can apply also when it is a single form.
Moreover, although the case where the high pressure water injection device is provided in the windshield has been described, it is needless to say that the present invention can also be applied to the case where it is provided directly in the horizontal portion of the main body frame.

  Furthermore, although the description has been given on the assumption that the car wash machine body is driven with respect to the vehicle, the present invention can be applied to a car wash machine in which the vehicle is driven with respect to the fixed car wash machine body.
