2. Description of the Related Art Generally, in an automobile maintenance shop which performs vehicle inspection and maintenance of a vehicle, the lower portion of the vehicle is cleaned in a maintenance process using a portal type car washer equipped with a lower cleaning device or a spray type high pressure car washer. However, since it takes time for natural drying after washing the lower part, the present applicant has previously filed Japanese Utility Model Application No. 3-2.
No. 9409 proposes a drying device for a vehicle lower part. In this apparatus, after washing the vehicle, high-pressure air is blown toward the lower part of the vehicle passing over the nozzle to dry the lower part of the vehicle.

[0003]

However, in the prior application, when the tire of the vehicle rides on the nozzle, the distance from the nozzle to the lower part of the vehicle increases, and the wind speed of the high-pressure air reaching the lower part of the vehicle is weakened. Could not be dried properly. Further, the distance from the nozzle to the tire house of the vehicle was further increased, and the drainage of the tire house having a complicated shape was extremely poor. The present invention has been made to address such a problem, and has improved the drying efficiency of a tire house portion of a vehicle.

[0004]

SUMMARY OF THE INVENTION In order to solve such problems, the present invention comprises a nozzle for blowing high-pressure air supplied from a blower upward, and a lower portion of a vehicle passing over the nozzle. A tire detecting means for detecting that a tire of the vehicle has passed over the nozzle, and an air volume increasing means for increasing an air volume of high-pressure air blown from at least the nozzle toward a tire house of the vehicle. And activating the air volume increasing means while the tire detecting means detects a tire of the vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view of a drying device for a vehicle lower part according to an embodiment of the present invention, FIG. 2 is a plan view of the drying device, and FIG.
FIG. 2 is a view taken along the line AA in which the blower 1 is omitted. 1
A blower driven by a motor 2 extends a duct 3 from an outlet, and a nozzle 4 is connected to a tip of the duct 3. The nozzle 4 is formed in an elongated box shape in the width direction of the vehicle, and blows high-pressure air upward from an air outlet 5 opened on one side in the longitudinal direction. 6, 6, 6, and 6 are slopes on which the vehicle gets on and off the nozzle 4, and 7, 7 are bridges extending between the slopes 6, 6, 6, and 6. The slopes 6, 6, and 6 are provided at both front and rear ends of the nozzle 4. , 6 are arranged, and bridges 7, 7 are arranged above the nozzle 4, and passing holes 8, 8 are formed in the bridges 7, 7 facing the outlet 5.

Reference numeral 9 denotes a switching plate for opening and closing the center of the outlet 5. One end of the switching plate 9 is rotatably supported by the end of the outlet 5. It is formed so that it can be displaced to the open position where the center is opened. 10
Is an air cylinder that operates the switching plate 9;
A bracket 11 in which the leading end of the lot 0 is fixed to the leading end of the switching plate 9 and the base end of the air cylinder 10 is fixed to the side surface of the nozzle 4
Compressed air is supplied in the direction in which the lot of the normal air cylinder 10 shrinks, the switching plate 9 is held at the open position, and high-pressure air is blown out uniformly from the blow-out port 5. By supplying compressed air in the direction in which the lot extends, the switching plate 9 is actuated to the closed position to cut off high-pressure air from the center of the outlet 5 and blow high-pressure air from both sides of the outlet 5. I have.

Reference numeral 12 denotes a tire detecting means for detecting that the tire of the vehicle is located on the nozzle 4. A pressure-sensitive switch responsive to a change in load is provided on the side of the outlet 5 through which the tire passes. Reference numerals 13a and 13b denote vehicle detecting means comprising photoelectric switches for detecting the entry of the vehicle, and a pair of light emitters 13a and light receivers 13b are opposed to both sides of the slopes 6 and 6 so as to obliquely cross the nozzle 4, and emit light from the light emitter 13a. The presence or absence of the vehicle is detected by transmitting the received light to the light receiver 13b or blocking the light by an object. Reference numeral 14 denotes a lamp for notifying the driver of the vehicle of a command to stop the vehicle, which is provided on one side of the vehicle exit side, and is turned on while detecting the tire of the vehicle.

Next, the operation of the present invention will be described.
FIG. 4 is a front view of the use state of the vehicle lower drying device of the present invention, and FIG. 5 is a flowchart showing the operation of the drying device. The vehicle lower drying device normally waits for the vehicle to enter by the vehicle detectors 13a and 13b (1). When the vehicle that has finished washing the lower part of the vehicle enters along the slopes 6 and 6, and the vehicle detecting means 13a and 13b detect the front end of the vehicle, the motor 2
The blower 1 is driven by the drive of, and high-pressure air is blown upward from the outlet 5 of the nozzle 4 to start drying to remove water droplets attached to the lower part of the vehicle (2), and wait for tire detection by the tire detection means 12. (3). When the vehicle moves forward and the tires ride on the bridges 7 and 7 and the tire detecting means 12 detects the tire, the lamp 14 is turned on to output a command to stop the forward movement of the vehicle to the driver, and to check the lot of the air cylinder 10. By extending the switching plate 9 to the closed position to close the central portion of the outlet 5 and blow out high-pressure air from both sides of the outlet 5 to the tire house,
The drying of the tire house is focused on (4).

The driver stops the forward movement of the vehicle for a while to dry the tire house, and when the drying of the tire house is completed, the driver advances the vehicle and restarts the drying of the lower part of the vehicle. When the tire detection state of the tire detection means 12 changes to the non-detection state due to the resumption of the forward movement of the vehicle, the lamp 14 is turned off to notify the driver of the end of the drying of the tire house portion and shorten the lot of the air cylinder 10. Then, the switching plate 9 is actuated to the opening position to open the center of the outlet 5, and high-pressure air is uniformly blown out from the outlet 5 to restart the lower part of the vehicle (5). When the lower part of the vehicle progresses and the vehicle detection state of the vehicle detection means 13a, 13b changes to the non-detection state, the operation of the blower 1 is stopped by stopping the driving of the motor 2 (6), and the lower part drying of the vehicle ends. .

In this way, when the tire of the vehicle is located on the nozzle 4, the supply ratio of the high-pressure air to the tire house is increased so that the tire house is mainly dried and the lower part of the vehicle can be dried uniformly. It is composed. In the embodiment, as the air volume increasing means, a configuration is described in which the central portion of the air outlet 5 is closed and the air volume of the high-pressure air blown out from both sides of the air outlet 5 toward the tire house is increased.
If the number of rotations of the motor 2 for driving the blower 1 is changed to increase the amount of high-pressure air blown out from the outlet 5 by increasing the number of rotations of the motor 2 when the vehicle rides on the nozzle 4, Drying can be performed sufficiently.

The present invention is configured as described above, and comprises a nozzle for blowing high-pressure air supplied from a blower upward, and a lower-part drying apparatus for drying a lower part of a vehicle passing over the nozzle. Tire detecting means for detecting that the tire has passed over the nozzle, and air flow increasing means for increasing the air flow of high-pressure air blown from at least the nozzle toward the tire house of the vehicle, wherein the tire detecting means is a vehicle. By operating the air volume increasing means while detecting the tire, the drying effect of the tire house portion of the vehicle is improved, and the entire lower part of the vehicle can be dried uniformly.
