JPH08318825A - Melting device for washing machine traveling rail - Google Patents

Abstract

PURPOSE: To prevent a washing machine from being suspended in running because its wheels are slipped/derailed owing to snow and frozen matters by providing a nozzle injecting fusing liquid melting snow and the like toward a traveling rail at the position in front of the wheel when the washing machine is reciprocally moved. CONSTITUTION: When a fusing function is selected for maintenance works, a washing machine 1 starts running from a running start point, and concurrently, starts injecting fusing liquid out of a injection nozzle 10. Every time when a pulse signal is inputted out of a rotary encoder 12 as the washing machine 1 is run, counts are added, and the washing machine is reciprocally run based on an added count value. Besides, when the washing machine 1 detects snow and frozen matters over a traveling rail 2 by an obstacle sensor 11, it is retreated by a specified distance, it then injects fusing liquid to snow and frozen matters, and thereby it keeps running to the end of the traveling rail 2 while the detection of snow and frozen matters and injection of fusing liquid are being repeated. The washing machine having arrived at the end of the rail, is returned to its running start point.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reciprocally travels on a running rail laid on the floor so as to straddle a stationary vehicle which removes dirt adhering to the vehicle body surface of a vehicle such as a passenger car. In particular, the present invention relates to a car wash machine in which snow and ice on the traveling rail are melted so that the car wash machine can safely travel back and forth.

[0002]

2. Description of the Related Art In a conventionally known car wash machine of this type, in winter or in cold regions, a method of circulating a heating fluid in the traveling rail freezes snow on the traveling rail or water attached to the traveling rail to wash the vehicle. There is known an anti-freezing device for a traveling rail (Jitsuko Sho 58-38003) which prevents the wheels of the machine from slipping or derailing and making traveling impossible.

[0003]

It can be said that such a conventional device is an effective device in a heavy snowfall region, but in recent years, it has been confirmed that the amount of snow and the number of days of snow have been extremely reduced due to the global warming phenomenon. In areas where it snows only a few times a year, including a car wash device, special equipment such as a circulating hose and circulation pump that circulates heating fluid inside the traveling rail is required, increasing production and management costs. ing. The present invention not only installs a special device on the traveling rail like the above-mentioned device, but installs a melting device for the traveling rail on the car wash machine main body to reduce production and management costs, and to reduce snow on the traveling rail. An object of the present invention is to provide a melting device for a car wash machine running rail, which prevents the wheel of the car wash machine from slipping or derailing due to ice or ice and thus making it impossible to run.

[0004]

DISCLOSURE OF THE INVENTION The present invention relates to a car wash machine which reciprocates on a traveling rail laid on the floor so as to straddle a stopped vehicle which is formed in a gate shape. A nozzle for injecting the melted liquid toward the traveling rail is provided at a position in front of the wheels, and the molten liquid such as hot water is sprayed and removed to snow and ice on the traveling rail.

According to the present invention, the injection nozzle is provided at a position forward of the wheel of the car washer in the traveling direction, so that the wheel of the car washer can be slipped or derailed by snow or ice on the traveling rail in winter or cold regions. A recirculation hose that prevents the traveling from being disabled and circulates the heated fluid in the traveling rail separately from the car wash device as in JP 58-38003.
Since no special equipment such as a circulation pump is required and hot water used for car washing in winter and cold regions can be diverted, production and management costs can be reduced. Further, the present invention can be used not only as a melting device for traveling rails in winter and cold regions but also as a cleaning device for removing pebbles and fallen leaves on traveling rails throughout the four seasons. The error can be eliminated and the traveling position can be detected more accurately.
