Guide wheels 6, 6, ..., 6 arranged at predetermined intervals on the outer peripheral side of the chain 4 by the electric motor 5 rotating the sprocket 3 push the tires on one side of the vehicle from the rear side to convey the vehicle. .. Reference numeral 7 denotes a temperature sensor provided in the fourth frame 1d, which corresponds to a detection unit that detects the temperature around the main body 1 and detects whether or not the antifreezing measure is necessary. As another detecting means, an operation section for selecting a car wash course may be provided with an antifreezing switch so that the antifreezing process can be carried out as necessary.

Reference numeral 8 is a washing block for washing a vehicle conveyed in the first frame 1a and the second frame 1b, and a pair of left and right front and side brushes for brushing a range from a front end surface of the vehicle to a rear side of a side surface. 9 and 9, a pair of left and right rear side brushes 10 and 10 for brushing the area from the front side of the vehicle to the rear end surface, and a top brush 11 for brushing and cleaning the upper surface of the vehicle, and are conveyed by the conveyor 2. Each brush 9, 9, 10, 10, 11 is applied to the surface of the vehicle while spraying the detergent solution onto the vehicle, and the stubborn dirt adhering to the surface of the vehicle is knocked off.

Reference numeral 12 denotes a wax coating block for applying wax to a vehicle conveyed in the third frame 1c after cleaning the vehicle, and a pair of left and right side brushes 13 and 13 for polishing the side surface of the vehicle, A top brush 14 for polishing the upper surface of the vehicle is provided, and each brush 13, 13, 14 is applied to the surface of the vehicle while spraying a wax liquid onto the vehicle that has been cleaned by the cleaning block 8 and is conveyed by the conveyor 2. Wax is applied to the surface of the vehicle by operating it.

Reference numeral 15 denotes a drying block that dries the vehicle conveyed in the fourth frame 1d after applying wax to the vehicle. A top nozzle 16 is provided above the fourth frame 1d and a side portion of the fourth frame 1d is provided. It is equipped with a pair of left and right side nozzles 17 and 17, respectively, and blows high-pressure air supplied from blowers 18 and 18 toward the vehicle to blow off water droplets adhering to the vehicle surface and remove water droplets adhering to the vehicle surface. is doing.

Next, the mounting structure of the front and side brushes 9 will be described based on FIGS. 2 and 3. FIG. 2 is a plan view of the front side brush 9 held in the standby position on the left side in the vehicle conveyance direction, and FIG. 3 is a perspective view thereof. The front side brush 9 is located on the front left side of the first frame 1a. From the standby position (solid line) of the front side brush 9 in which the arm 19 is rotatably suspended and supported by the tip of an arm 19 which is pivotally supported, and the arm 19 is substantially parallel to the transport direction of the vehicle, the arm 19 extends from the vehicle. It is formed so as to be rotatable between the operating positions (dotted lines) of the front and side brushes 9 which are substantially perpendicular to the conveyance direction of. Reference numeral 20 is an electric motor fixed to the lower surface of the arm 18, and rotationally drives the front and side brushes 9 via a transmission mechanism (not shown).

Reference numeral 21 denotes a spring connected between the arm 19 and the first frame 1a at an appropriate position, and biases the front and side brushes 9 in a direction to press them against the vehicle. Reference numeral 22 denotes an air cylinder connected between the arm 19 and the side of the first frame 1a. The compressed air is supplied in a direction that shortens the lot portion of the normal air cylinder 22 to move the front side brush 9 to the first side. The front and side brushes 9 are applied to the vehicle by holding the frame 1a at a standby position on the side thereof, releasing the bias by the air cylinder 22 during vehicle washing, and biasing the spring 21. Reference numeral 23 denotes a pipe-shaped contact provided at a position where the front side brush 9 comes into contact when the front side brush 9 is rotated while the front side brush 9 is held at the standby position and in parallel with the axis of the front side brush 9. With the contact member, the front side brush 9 that has been returned to the standby position after the brushing cleaning of the vehicle is idled and the liquid adhering to the front side brush 9 is knocked off to drain the front side brush 9. The front and side brushes 9 are prevented from freezing. Similar contact members are provided at the standby positions of the side brushes 9, 10, 10, 13, 13 arranged on the first to third frames 1a, 1b, 1c.

Next, a mounting structure of the top brush 11 will be described with reference to FIG. FIG. 4 is a side view in which the top brush 11 is held at the standby position. The top brush 11 is rotatably supported between the front and rear ends of an arm 25 that is swingably held on both sides of the second frame 1b via a support shaft 24. It is formed so as to be able to move up and down from a standby position (solid line) where the top brush 11 is supported and above the second frame 1b to a lower limit position (dotted line) where the top brush 11 hangs down. Reference numeral 26 denotes an electric motor fixed to the arm 25, which rotationally drives the top brush 11 via a transmission mechanism (not shown). Reference numeral 27 denotes an air cylinder connected between an operating arm 28 fixed to the arm 25 and an appropriate portion of the second frame 1b. Normally, compressed air is supplied in a direction of shortening the lot portion of the air cylinder 27 to wait for the top brush 11. When the vehicle is washed, the air cylinder 27 releases the urging force to lower the top brush 11 so that the top brush 11 acts on the upper surface of the vehicle. Reference numeral 29 denotes a pipe-shaped abutting member provided at a position where the top brush 11 comes into contact when the top brush 11 is rotated with the top brush 11 held at the standby position and in parallel with the axis of the top brush 11, The top brush 11 which has been returned to the standby position after the brushing cleaning is idly rotated to knock off the liquid agent adhering to the top brush 11 to drain the top brush 11 to prevent the top brush 11 from freezing. A similar contact member is also provided at the standby position of the top brush 14 arranged on the third frame 1c. Alternatively, the frame of the frame or the wall surface above the frame may be used as the contact member.

FIG. 5 is a block diagram of the control unit, and 30 is a control device including a microcomputer, which controls the drive of the conveyor 2, the opening / closing operation of each brush, and the rotational drive. When the control device 30 detects the start of car wash, it starts the transportation of the vehicle by driving the conveyor 2, and causes each brush to act on the corresponding part of the vehicle at a predetermined timing based on the traveling distance of the vehicle to brush the vehicle surface. To do. Here, when the outside air temperature detected by the temperature sensor 7 is equal to or higher than the predetermined temperature, the brush is returned to the standby position and the rotation of the brush is stopped after the brushing of the corresponding portion of the vehicle is completed, so that the outside air temperature is the predetermined temperature. If the temperature drops below the specified value, the brush that has been brushed at the relevant part of the vehicle is returned to the standby position as a process to prevent the brush from freezing, and the brush is idled for a certain period of time to knock off the liquid agent attached to the brush and drain the brush. To prevent the brush from freezing. When the liquid agent attached to the brush is removed, the brush can be applied to the surface of the vehicle with peace of mind without fear of the brush freezing even if the outside air temperature drops.
