  By the way, according to the above-described conventional configuration, the oscillation speed of the injection nozzle is changed in accordance with the traveling speed of the car wash machine so that no washing is left on the roof portion of the vehicle. For example, the travel speed of the car wash machine is high. The higher the swing speed is. However, as shown in FIGS. 10A and 10B, since the spread angle of the injection from the injection nozzle is constant, the vehicle with a higher vehicle height has a roof portion than the vehicle with a lower vehicle height. The area (also referred to as width) of the injection region on the surface is narrowed.

  By the way, conventionally, the spraying area of the cleaning liquid sprayed from both the spray nozzles 51 is set so as to fit the roof of a vehicle having a low vehicle height, such as a sedan type, that is, no washing residue is generated. For this reason, there is a problem in that a vehicle with a high vehicle height, such as a one-box car that is a cab-over type, is left unwashed (non-injection region) on the roof.

  By the way, the gist of the present invention is to adjust the swing speed of the spray nozzle according to the height of the vehicle. Among various liquid spray devices, the high pressure water spray device for spraying high pressure water to the vehicle. Is suitable. Therefore, the following description will be given focusing on this high-pressure water injection device. The parts using high-pressure water include, for example, pre-cleaning and finish-cleaning. Here, as shown in FIGS. 1 and 2, cleaning is performed with wax or the like provided at the rear of the front body 2. The high-pressure water injection device 21 used for finish cleaning for injecting water will be described. Of course, the present invention can also be applied to the pre-cleaning high-pressure water injection device 22 provided at the front portion of the front body 2.

  In the present invention, as described above, in order to adjust the rocking speed of the injection nozzle in accordance with the height of the vehicle (also referred to as the vehicle height), as shown in FIGS. The detected height detected by a vehicle height detector (also referred to as a shape detector) 41 arranged in the pedestal portions 2b and 2b is used. As the vehicle height detector 41, a photoelectric sensor is used. In other words, a plurality of photoelectric sensors each having a light emitting portion and a light receiving portion are arranged on the left and right pedestal portions 2b at predetermined intervals, and the mounting height of the photoelectric sensor whose light is blocked by the vehicle body is a vehicle. It is detected as high.

  As shown in FIGS. 4 to 7, the high-pressure water injection device 21 has a horizontal frame material of a windshield portion 2 c that protrudes rearward from the front body 2 on the horizontal portion 2 a side of the front body 2. A support frame member 23 mounted in the horizontal direction near the rear of 2d and in the center portion, and can be rotated around a horizontal axis in the front-rear direction at the left and right positions of the support frame member 23 via bearings 24, respectively. An elbow joint 25 which is a rotation support type joint member provided, a swing lever 26 (26A, 26B) having one end connected to the upper portion of the hand 25, and both swing levers 26A, 26B, a first connecting rod 27 that is a connecting member for connecting the other end portions of each other, an electric motor 28 provided near the center of the support frame member 23, and a speed adjusting unit 29 for adjusting the rotational speed of the electric motor 28. When A rotary member 30 attached to the output shaft 28a of the electric motor 28, a second connecting member that connects the tip end portion (free end portion) of the rotary lever 30 and the other end portion of the one swing lever 26A. The connecting rod 31, the high pressure water injection nozzle 32 (32A, 32B) connected to the lower connection port 25a which is one end side of each of the elbow joints 25, and the upper side which is also the other end side of the elbow joint 25 The high-pressure water supply pipe 33 is connected to the connection port 25b. The shaft portion 25c of the elbow joint 25 supported by the bearing 24 corresponds to a horizontal support shaft, and the swing lever and the electric motor 28 constitute a swing drive device.

  The ends of the high-pressure water supply pipe 33 are joined together and connected to a pump (not shown) as a single supply pipe. The swing lever 26 and the first connecting rod 27 that swing the left and right injection nozzles 32A and 32B in synchronism with each other can also be referred to as a connecting mechanism.

Further, the ends of the high-pressure washing water supply pipe 33 are joined together and connected to a pump (not shown) as a single supply pipe.
As shown in FIG. 7, the speed adjusting unit 29 inputs the vehicle height detected by the vehicle height detector 41 and determines the rotational speed of the electric motor 28 according to the vehicle height value; A speed control unit (for example, an inverter) 43 that controls the rotation speed of the electric motor 28 by inputting the rotation speed from the speed determination unit 42 is configured. Further, when determining the rotational speed from the vehicle height value, for example, an expression or a table (so-called look-up table) indicating the relationship between the vehicle height and the rotational speed is used.

  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. Pre-cleaning is performed by the pre-cleaning high-pressure water jet device 22 provided at the front of the head.

  Next, after the detergent is sprayed by the detergent spraying device, the finish cleaning liquid spraying device provided at the rear portion of the front body 2, that is, the high-pressure water spraying device 21 according to the present invention, together with the wax for finishing. Wash water is jetted. Of course, although not explained, the brushing means are also activated. After the brushing and cleaning, the rear main body 3 continues to blow air from the drying nozzle to the vehicle C to perform drying.

Here, the cleaning by the high-pressure water injection device according to the present invention will be described.
When cleaning by the high-pressure water injection device 21 is started, the vehicle height value detected from the vehicle height detector 41 provided in the front main body 2 is input to the speed adjustment unit 29.

  Then, the speed determining unit 42 of the speed adjusting unit 29 obtains the rotational speed corresponding to the vehicle height value from the table, and the obtained rotational speed is input to the speed control unit 43 to control the electric motor 28. For example, normally, when the swing speed of the injection nozzle 32 is determined in accordance with a vehicle having a low vehicle height, when the vehicle having a high vehicle height is washed, the swing speed of the injection nozzle 32 is determined according to the height. Will be faster.

Here, the injection state in the roof part of a vehicle is demonstrated.
For example, when the injection nozzle 32 is swung in accordance with a vehicle having a low vehicle height, the injection region at the roof portion of the vehicle, that is, the injection width, becomes narrower as the vehicle height increases. FIG. 8A shows the injection width A when the vehicle height is low, and FIG. 8B shows the injection width B when the vehicle height is high. That is, as shown in FIG. 8B, when the vehicle height is high, an uninjected region D is generated.

  However, when the oscillation speed of the injection nozzle 32 is increased, as shown in FIG. 8C, an uninjected region generated between the injection regions in the forward path and the backward path can be eliminated. Of course, the set rocking speed and the vehicle height are in such a relationship that there is no unwashed area (uninjected area).

  According to the above configuration, since the swing speed of the injection nozzle provided so as to be swingable in the left-right direction is adjusted according to the vehicle height, that is, as the vehicle height increases, the speed increases. Regardless of the height, for example a sedan or a one-box car, it is possible to prevent unwashed parts from being left on the roof.

  In the above-described embodiment, the traveling speed of the front main body and the rear main body, that is, the main body frame is not particularly described, but the case where the traveling speed of the main body frame is constant is described.

  By the way, in the said embodiment, although demonstrated as what adjusts the rocking | fluctuation speed of an injection nozzle according to the vehicle height detected by the vehicle height detector, for example, an operator visually checks the vehicle height on the operation panel. And the rocking speed of the injection nozzle may be adjusted according to the input vehicle height value.

  Further, in the above-described embodiment, the description is applied to the high-pressure water ejecting apparatus that performs the pre-cleaning and the finishing cleaning, but of course, it may be applied to any liquid ejecting apparatus of the pre-cleaning or the finishing cleaning. The present invention can also be applied to other liquid ejecting apparatuses that do not require high pressure.

Moreover, in the said embodiment, although the case where the car-washing machine main body was a separation | separation form of a front part main body and a rear part main body was demonstrated, it is applicable 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.
