Next, a configuration for reducing noise generated during a car wash operation in the car wash machine that is the gist of the present invention will be described.
In short, in the drying process of this car wash machine, drying nozzles such as top nozzles and side nozzles that are blown out by the activation of the blower device were detected by a vehicle detector provided in the car wash machine body. When the vehicle is moved to the end position in the front-rear direction of the vehicle, the number of rotations (or the number of rotations) of the motor that rotates the blades of the blower device is controlled to be a predetermined number of rotations set in advance. It is a thing.

  Here, as shown in FIG. 1, the front portion of the vehicle 6 is stopped at the front end side (traveling end position side) of the car wash machine main body 10, and the vehicle is washed. In the (return), drying starts from the rear end position of the vehicle 6, and therefore, noise is generated until the car wash machine main body 10 reaches (moves) from the travel end position b to the rear end position of the vehicle 6. Is reduced.

  That is, as shown in FIG. 8, the car wash machine 1 is provided with an encoder (an example of a movement amount detector) 61 that detects the amount of movement of the car wash machine body 10 and a front part of the car wash machine body 10. 6, a vehicle detector 62 that can detect 6, and a control device 63 that inputs detection signals from these detectors 61 and 62 and controls the rotational speed of the motor 33 that rotates the blade body 35 of the blower device 31. Has been.

  The control device 63 receives a detection signal from the encoder 61 and detects (calculates) a travel position with respect to the travel start end position a of the car wash machine body 10, and from the travel position detection unit 71. A vehicle position detector 72 that receives a travel position and a detection signal from the vehicle detector 62 to detect a vehicle position (including vehicle height, that is, vehicle shape data at each position in addition to the front and rear end positions of the vehicle). And a target distance calculation unit that inputs a vehicle position detected by the vehicle position detection unit 72 and calculates a target distance (also referred to as a control distance) from the travel end position (reference position) b to the rear end position of the vehicle 6. 73 and the target distance obtained by the target distance calculation unit 73 and the current set speed of the car wash body 10 set by the speed setting unit 74 and the car wash machine book 10 is an arrival time calculation unit 75 that calculates an arrival time until the drying nozzles such as the top nozzle 25 and the side nozzle 28 reach the rear end position of the vehicle 6, and this arrival time calculation unit 75. The obtained arrival time is input, and after the arrival time has elapsed, the inverter 64 of the motor 33 is set so that the rotational speed of the blade body 35, that is, the motor 33 is just a predetermined rotational speed (for example, the rotational speed during normal operation). In addition, a frequency control unit 76 that outputs a frequency command so as to increase the rotational speed sequentially. Here, the control device 63 is described as a drying means, but actually, it is provided in the car wash machine main body 10 for controlling the entire car wash machine. A control function for other devices is also provided, but the description thereof is omitted.

The encoder 61 detects, for example, the rotational speed of the traveling wheel 13 and may be provided on the traveling drive device (drive motor, reducer, etc.) side.
As the vehicle detector 62, as shown in FIG. 9, for example, a plurality of photosensors 62a (also referred to as area sensors) arranged at predetermined intervals in the vertical direction are used. However, the position of the upper surface of the vehicle 6 (which is the height of the vehicle body) can be detected, and the position where the optical axis in the photosensor 62a is first blocked is the rear end position of the vehicle 6 ( Alternatively, it can be detected as a front end position).

  In the above configuration, when the car 6 is washed, the car wash machine body 10 is moved to the travel start position a, that is, the car wash start position, and the front end of the vehicle 6 is at a predetermined position on the front side of the car wash machine body 10. The car wash is started while 6 is stopped.

  When the car wash is started, the car wash machine main body 10 starts to travel from the front end to the rear end of the vehicle 6, and cleaning liquid such as cleaning water is ejected from the nozzles 14 to 19 serving as cleaning means, The outer surface of the vehicle 6 is brushed by the brushes 20 to 22 and cleaned. In the cleaning process that is the forward path, the vehicle position detection unit 72 detects the front and rear end positions of the vehicle 6 and the vehicle height, that is, vehicle shape data, and these data are stored in a storage area (not shown). Will be.

When the vehicle 6 has been cleaned and the traveling end position b is reached, the traveling direction of the car wash machine body 10 is reversed and the drying process is started.
When the drying process is started, the blower device 31 is first activated. At this time, the control device 63 controls the inverter 64 of the motor 33. That is, the vehicle position data detected by the vehicle position detection unit 72 is input to the target distance calculation unit 73, where the target distance from the travel end position b to the rear end position of the vehicle 6 is obtained. Next, the target distance and the set speed of the car wash machine body 10 are input to the arrival time calculation unit 75, and the drying nozzles such as the top nozzle 25 and the side nozzle 28 of the car wash machine body 10 are placed at the rear end position of the vehicle 6. The arrival time until the arrival is obtained, and this arrival time is further input to the frequency control unit 76. After the arrival time has elapsed, the rotational speed of the motor 33 that rotates the blade body 35 is just the predetermined rotational speed, that is, normal operation. A frequency command is output to the inverter 64 so that the rotation speed becomes the hour.

  Therefore, as compared with the conventional case where the blade body is rotated at the rotation speed at the normal operation from the time when the drying process is started at the travel end position b, the predetermined rotation speed is set at a predetermined portion. Since the rotational speed of the blades is increased sequentially, the amount of noise generated in the blower device can be reduced.

  Note that when the drying air is ejected from the nozzles 25 and 28 and the vehicle 6 is dried, the air passes through the duct. Regarding the noise generated at this time, the sound absorbing material disposed around the air is passed. The sound is absorbed by 23, 43, and 53, and its size is reduced.

  By the way, in the above-described embodiment, it has been described that the motor is controlled so that the rotation speed during normal operation is reached when the drying nozzle reaches the end position of the vehicle, for example, the rear end position. When the air ejected from the drying nozzle is for forming an air curtain for preventing the cleaning liquid ejected in the cleaning process from splashing, a predetermined position (vehicle) The motor is controlled so that the rotational speed during normal operation is reached when the vehicle reaches a predetermined relative position) or a side position (predetermined part) of the vehicle.

  Moreover, in the said embodiment, when the nozzle for drying reached | attained the edge part position (predetermined site | part) of a vehicle, it demonstrated so that the rotation speed of the motor which rotates a blade body might become the rotation speed at the time of a normal driving | operation. However, for example, in the cleaning process, when the blower device is operated at a lower rotational speed than during normal operation, the drying nozzle is located at the end position (predetermined part) of the vehicle or at a predetermined position away from the vehicle. When reaching (predetermined relative position with respect to the vehicle), the control is naturally performed so that the rotational speed is low.

  Furthermore, in the said embodiment, although the case where the car-washing machine main body was comprised with one traveling body was demonstrated, for example, when the car-washing machine main body is a separated structure (the case where it is comprised with two traveling bodies) ) That is, a cleaning traveling body (also referred to as No. 1 machine) provided with cleaning nozzles such as a first detergent nozzle, a water repellent coating agent nozzle, a second cleaning water nozzle, a second detergent nozzle, and a wax nozzle, and a top nozzle The present invention can also be applied to a case where a drying traveling body (also referred to as No. 2 machine) provided with a drying nozzle such as a side nozzle is provided.

  In this case, after the cleaning traveling body cleans the vehicle, the drying traveling body performs drying later. Therefore, the vehicle position can be detected by the encoder and the vehicle detector provided on the cleaning traveling body. Therefore, by using the vehicle position data, when the drying nozzle reaches the air ejection position (predetermined relative position with respect to the vehicle) with respect to the vehicle, the rotational speed of the motor is controlled to be the predetermined rotational speed.
