[0012] In the embodiments of the present invention, the description will be divided into a plurality of sections, etc., as necessary, but in principle, they are not unrelated to each other, and one is related to the other as a partial or complete modification, detail, etc. For this reason, in all the drawings, members having the same function are given the same reference numerals, and repeated description thereof will be omitted.

[0013] In addition, the number of components (including the number, numerical value, amount, range, etc.) is not limited to a specific number, and may be more or less than a specific number, unless otherwise specified or clearly limited in principle to a specific number. In addition, when referring to the shape of a component, etc., it includes things that are substantially similar or similar to that shape, etc., unless otherwise specified or clearly considered not to be the case in principle.

[0014] A vehicle processing device according to an embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a schematic front view of a vehicle processing device according to an embodiment of the present invention. Fig. 2 is a right side view of the vehicle processing device shown in Fig. 1. Note that, for ease of explanation, some parts of the figure are shown with dashed lines. Also, some internal mechanisms of the vehicle processing device are omitted.

[0015] The vehicle treatment device 10 has a gate-like shape and includes legs 12, 12 and a beam 13 that spans the legs 12, 12. The legs 12, 12 and the beam 13 are covered with decorative plates 71 to 77 (hereinafter, also referred to as decorative plate 70) made of, for example, sheet metal. The front of the vehicle treatment device 10 is provided with decorative plates 71, 71, 72, the back is provided with decorative plates 77, 77, 78, the right side is provided with a decorative plate 75, the left side is provided with a decorative plate (not shown), the flat surface is provided with a decorative plate 76, and the inner surface is provided with decorative plates 73, 73, 74. The vehicle treatment device 10 performs treatments such as washing, wax coating, and drying on a vehicle C that is parked or passing between the legs 12, 12. Therefore, parts of the decorative plates 73, 73, 74 are open so that a washing liquid or a gas for drying can be sprayed onto the vehicle C.

[0016] The vehicle processing device 10 is equipped with a drying device 20 that dries the vehicle C. The drying device 20 is equipped with a top nozzle 22 that blows air mainly toward the upper surface of the vehicle C, and side nozzles 21, 21 that blow air mainly toward the side surfaces of the vehicle C. The top nozzle 22 is provided on a beam portion 13 of the vehicle processing device 10. The side nozzles 21, 21 are provided on legs 12, 12 of the vehicle processing device 10. In addition, the top nozzle 22 has a lifting function so that it can rise and fall along the shape of the upper surface of the vehicle C.

[0017] Fig. 4 is a front view of the blower 30 (the blower 30 on the right side in Fig. 1) provided on the left leg of the vehicle treatment device 10 shown in Fig. 1. Fig. 5 is a cross-sectional view taken along line A-A' in Fig. 4, and Fig. 6 is a bottom view of the blower 30. The drying device 20 is equipped with the blower 30 which blows air to the side nozzles 21, 21 and the top nozzle 22. The blower 30 is provided on the upper ends of the legs 12, 12 (or both ends of the beam portion 13).

[0018] The blower 30 includes a box 31, and a casing 50 is provided in the box 31. Furthermore, a fan 53 and a motor 54 that is a drive source for the fan 53 are housed in the casing 50. An intake port 52 is provided on the rear side of the casing 50, and the intake port 52 is open to draw in gas. The intake port 52 is provided with an intake cone 51 that spreads radially from inside the casing 50 toward the intake port 52 to facilitate drawing in the gas into the casing 50. In the blower 30, the fan 53 rotates when driven by the motor 54. The rotation of the fan 53 allows the gas to be drawn into the casing 50 from the intake port 52. The casing 50 also includes an exhaust port 55 that exhausts the drawn in gas. The drawn in gas passes through the exhaust port 55 and can move to a branch pipe 60, which will be described later.

[0019] The blower 30 is provided with a box 31 that houses the casing 50. The box 31 is for reducing the driving noise of the motor 54. The box 31 is provided with a first intake port 32 for taking in gas on the front side. The first intake port 32 is provided with a cover 36. The cover 36 is provided so that the first intake port 32 opens toward the side where the decorative plate 70 is not provided. To be more specific, as shown in Figs. 1 and 2, decorative plates 71, 72, 73, 75, 76, 77, and 78 are provided around the blower 30. The cover 36 covers the first intake port 32 so that the opening direction of the first intake port 32 is not directed toward the decorative plates 71, 72, 73, 75, 76, 77, and 78. In other words, the cover 36 is provided so that the opening direction of the first intake port 32 opens downward. By providing a cover 36 so that the opening direction of the first air intake 32 is not directed toward the decorative panel 70, the first air intake 32 is less likely to vibrate the decorative panel 70 when the blower 30 takes in air, and the noise emitted from the vehicle processing device 10 is reduced.

[0020] The bottom surface of the box 31 is provided with a second intake port 34. The second intake port 34 is open so that air can be drawn into the box 31. The second intake port 34 is preferably punched, meshed, or slit-shaped to prevent foreign objects from entering the blower 30. The second intake port 34 is provided on the bottom surface of the box 31, so that heat generated from the motor 54 can be exhausted. The second intake port 34 is provided on the bottom surface, so that the decorative panels 71, 72, 73, 75, 76, 77, and 78 are less likely to vibrate when air is drawn in. In other words, the opening direction of the second intake port 34 is not directed toward the decorative panels 71, 72, 73, 75, 76, 77, and 78. The opening of the second intake port is not directed toward the decorative panel 70 to prevent the decorative panel 70 from vibrating. By making it difficult for the decorative panel 70 to vibrate, the vibration noise is reduced. Furthermore, when air is drawn in by the blower 30, a pressure difference occurs between the inside and outside of the box 31, causing a whistling noise. However, by providing the second air intake 34 in the box 31, the pressure difference between the inside and outside of the box 31 is reduced, and the whistling noise of the box 31 can be reduced.

[0021] It is preferable that the combined area of ​​the openings of the first intake port 32 and the second intake port 34 of the box 31 is the same as (or close to) the opening area of ​​the suction port 52 of the casing 50. By setting the combined area of ​​the openings of the first intake port 32 and the second intake port 34 of the box 31 to be the same as the opening area of ​​the suction port 52 of the casing 50, the pressure difference between the inside and outside of the box 31 is reduced. In other words, the whistling phenomenon of the blower 30 is reduced.

[0022] An opening 33 is provided on the bottom surface of the box 31. The exhaust port 55 of the casing 50 and the intake port 66 of the branch pipe 60 described later are connected so that gas can flow through them. Therefore, the opening 33 of the box 31 is for the exhaust port 55 of the casing 50 and the intake port 66 of the branch pipe 60 to pass through.

[0023] FIG. 7 is a front view of the branch pipe 60, and FIG. 8 is a rear view of the branch pipe 60. FIG. 9 is a vertical cross-sectional view of the silencer 61. The arrows in FIG. 9 indicate the volume and flow of sound. The drying device 20 is provided with a branch pipe 60 at the bottom of the blower 30 (FIG. 1). The branch pipe 60 has an intake port 66. The intake port 66 is connected to the exhaust port 55 of the casing 50. This allows the gas sent from the blower 30 to flow into the branch pipe 60. The branch pipe 60 branches the gas sent from the blower 30 into the side nozzles 21, 21 and the top nozzle 22.

[0024] A silencer 61 is provided on the back and bottom of the branch pipe 60. The silencer 61 can absorb wind noise emitted from the blower 30, driving noise of the motor 54, rotation noise of the fan 53, and the like. The silencer 61 is partially open so that the gas flowing through the branch pipe 60 can flow in. The silencer 61 is provided with a sound absorbing material 62. It is preferable to use a plurality of types of sound absorbing materials 62 in layers for the silencer 61. It is preferable to use aluminum fiber sound absorbing material or glass wool for the sound absorbing material 62. The sound absorbing material 62 is provided on the opening side of the branch pipe 60. On the other hand, a gap 63 is provided on the side wall side of the silencer 61. The sound flowing in from the branch pipe 60 is absorbed by passing through the two layers of sound absorbing material 62. Then, the sound passes through the gap 63 and hits the side wall of the silencer 61 and bounces off. The bounced sound is absorbed by passing through the two layers of sound absorbing material 62 again.

[0025] The branch pipe 60 has an exhaust port 64 that exhausts gas to the side nozzle 21 and an exhaust port 65 that exhausts gas to the top nozzle 22. The exhaust ports 64, 65 allow the gas sucked by the blower 30 to be branched into the side nozzle 21 and the top nozzle 22. In addition, the silencers 61, 61 can absorb wind noise passing through the branch pipe 60.

[0026] The exhaust port 65 that discharges gas into the top nozzle 22 is provided with a blower duct 24 that connects the exhaust port 65 to the top nozzle 22 (FIG. 1). The blower duct 24 is a displaceable tube, and as described above, when the top nozzle 22 moves up and down, the blower duct 24 can also displace in accordance with the movement of the top nozzle 22.

[0027] The operation of the vehicle treatment device 10 will be described below. The vehicle treatment device 10 washes and waxes the vehicle C parked or passing between the legs 12, 12, and then dries the vehicle C using the drying device 20. More specifically, the motor 54 drives the fan 53 to rotate. The rotation of the fan 53 causes gas to be sucked into the box 31 from the first air intake 32 and the second air intake 34. The gas blown by the drying device 20 is blown toward the vehicle C so as to blow away moisture adhering to the vehicle C. On the other hand, when the motor 54 drives, the fan 53 rotates and gas is sucked into the box 31. When gas is sucked in, a pressure difference occurs between the inside and outside of the box 31, causing a whistling phenomenon. However, the presence of the second air intake 34 reduces the pressure difference between the inside and outside of the box 31, and the whistling phenomenon of the box 31 can be reduced. In addition,

[0028] A cover 36 is provided on the first intake port 32. The cover 36 causes the first intake port 32 to open toward the side (downward) of the vehicle processing device 10 where the decorative plate 70 is not provided. As a result, even if gas is drawn into the first intake port 32, the decorative plate 70 is less likely to vibrate, and vibration noise is less likely to occur.

[0029] Moreover, the box 31 is provided so that the combined area of ​​the openings of the first intake port 32 and the second intake port 34 is equal to the opening area of ​​the suction port 52 of the casing 50. This reduces the air pressure difference between the inside and outside of the box 31, and reduces the whistling phenomenon of the blower 30.

[0030] Furthermore, the driving sound of the motor 54 and the sound generated by the rotation of the fan 53 are emitted from the first air intake 32. However, by using the cover 36 to orient the opening direction of the first air intake 32 downward, the driving sound of the motor 54 and the rotation sound generated by the rotation of the fan 53 are emitted downward. By being emitted downward, some of the driving sound, rotation sound, and other sounds are absorbed by the installation surface G on which the vehicle processing device 10 is installed. On the other hand, a small amount of sound is generated that is not absorbed by the installation surface G and is reflected. However, such sounds are attenuated within the vehicle processing device 10 and are not easily diffused to the surroundings.

[0031] The gas sucked into the blower 30 flows into the intake port 52 of the casing 50. Since the intake port 52 has an intake cone 51, the flow rate of the gas increases. The gas that flows into the casing 50 is discharged from the exhaust port 55 and flows into the intake port 66 of the branch pipe 60. Since the branch pipe 60 is provided with a silencer 61, the silencer 61 absorbs wind noise, the driving sound of the motor 54, the rotation sound of the fan 53, and the like. Thereafter, the gas discharged from the exhaust port 64 of the branch pipe 60 moves to the side nozzle 21 and is blown mainly toward the side of the vehicle C. In addition, the gas discharged from the exhaust port 65 of the branch pipe 60 passes through the blower duct 24 and moves to the top nozzle 22. The top nozzle 22 blows the gas toward the upper surface while moving up and down along the shape of the vehicle C.

[0032] The present invention has been described above with reference to the preferred embodiments, but the present invention is not limited to the above-described embodiments, and the shape and configuration can be modified without departing from the spirit of the present invention.
