Description

[Detailed Description of the Invention] This invention relates to a washing machine for automobiles, and is designed to stop a traveling washing machine that moves and cleans the vehicle. Generally, this type of device detects the movement of the washer to a predetermined position using a switch mechanism installed at the bottom of the traveling washer, but it is necessary to reliably prevent malfunctions, so the control stroke of the switch is increased. In addition, measures were taken to eliminate vibrations in the switch operating mechanism. This invention relates to improvements based on these, and will be explained below with reference to drawings showing examples. Reference numeral 1 refers to a guide rail installed on the floor, and a cleaning brush 2, a drying nozzle 3, a watering nozzle 4, etc. are installed on this rail 1. A traveling washing machine 6 equipped with a washing mechanism 5 is provided. 7 is a traveling motor of the traveling washer 6, 8 is a drive motor for the cleaning brush 2, 9 is a dry air blower, and 10 is a rotary rod provided at the bottom of the traveling washer 6, which is bent into an approximately 90° shape, for example. The halfway bent portion is rotatably supported by a shaft 11,
And at one horizontal end of the rotating rod 10, there is a rotating rod 1.
A spring 12 is energized to keep the rotating rod 10 tensioned at a normal position, that is, a position where the rotating rod 10 is not moved by an external force. Further, a switch rod 13 is connected to one end on the horizontal side, and an operating section 14 is formed at the tip of the switch lever 13, and the operating section 14 is sandwiched between the switch rods 13 and 13 for turning off and on the power supply to the circuit of the traveling motor 7 of the traveling washer. Switches 15 and 15' are provided at different positions and control the movement of the traveling washer 6 by turning off and on the power supply to the traveling motor 7. In addition, in the illustration, a magnetic material G is provided on the operating section 14, and the switch 1
Reed switches 5 and 15' are used to open and close one of the switches 15 and 15' by changing the position of the operating section 14. 16
The rotating rod 10 rolls on one surface of the guide rail with a guide ring provided at one end of the hanging side of the rotating rod 10, and by contacting a protrusion 17 provided on the guide rail, the rotating rod 10 resists the bias of the spring 12. It tilts around the shaft 11 and moves the switch rod 13 up and down. Further, although this protrusion 17 is provided on one side of the guide rail, it may be provided near the guide rail 1, and in this case, the end of the rotating rod 10 is appropriately bent to face the protrusion 17. This invention is constructed as described above, and has a rotary rod that is bent at approximately 90 degrees and rotatably supported at the bottom of the traveling washer that runs on the traveling guide rail laid on the floor. A guide wheel rolling on a rail is attached to one end of the hanging end of the rotating rod, and a guide wheel that rolls on the rail is brought into contact with a protrusion provided at a predetermined position on the rail to tilt the rotating rod. The rotary rod is equipped with a spring that biases the rotary rod to the normal position to keep the rotary rod biased in the normal position, and a switch rod is provided at the horizontal end of the rotary rod so that the rotary rod is connected to the switch rod by tilting. The switch that controls the energization to the travel motor of the travel cleaning mechanism installed in the vehicle opens and closes, and the movement of the travel washer is protruded, allowing reliable operation to stop the travel washer at a predetermined position during car washing. 13 is energized by a spring to hold it in its normal position and rolls on the guide rail surface, and is taken out as a vertical deviation difference by a rotary rod that tilts when it comes into contact with a protrusion provided on the guide rail. When the washer moves on the rail, the guide wheel allows the washing machine to move smoothly on the rail, and there is no risk of the guide wheel rolling on the protrusion and climbing up on the incline, thereby causing accidental operation.
In addition, in order to keep the rotating rod in its normal position, the spring is energized so that the horizontal part of the rotating rod is taut, so the swinging of the rotating rod can be suppressed with a single spring, allowing the robot to travel on the rail. This has practical effects such as being able to reliably eliminate malfunctions due to vertical vibrations.
