Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floor cleaning device for a car wash room in a car wash device for large vehicles such as trucks and buses, and in particular to an unmanned cleaning device for the floor surface of a car wash room by utilizing a car wash pump. The present invention relates to a floor cleaning device that is designed to

Conventionally, washing large vehicles has relied on hand washing, and because the washing area is larger and dirtier than that for passengers, it takes two to four hours to wash one car.
Additionally, workers washed cars in unfavorable working conditions, wearing raincoats to prevent wash water and muddy water from splashing onto their work clothes. On the other hand, car wash equipment for small vehicles, such as those installed at gas stations, where the car is moved while the vehicle is stopped, is too large for large vehicles, so it is not practical. The current situation is that it cannot be provided. Therefore, as a car wash device for such a large vehicle, the car wash device is kept stationary, the vehicle is allowed to move through it, and high-pressure washing water is sprayed onto the vehicle to wash the vehicle in a short time. A possible example is a car wash device.

However, large vehicles such as trucks often drive on rough roads, so they are often dirty with mud and oil, and in car wash rooms, many vehicles are washed continuously.
Mud, oil, etc. that fall off the vehicle become sludge and accumulate all over the floor. Conventionally, this had to be cleaned manually by pouring water from a high-pressure pump hose, using a brush, mop, etc. This has resulted in the disadvantage that cleaning the floor surface is difficult and takes a long time.

Furthermore, Japanese Patent Application Laid-Open No. 16529/1983 discloses an automatic spraying device for spraying insecticide, disinfection, and deodorizing liquid onto cleaning trucks, etc., in which the device is stopped and the vehicle is moved to spray insecticide on the vehicle. However, this prior art example does not disclose a car washing device and also does not disclose a device for washing a floor surface. Also, in 1987-28048,
A tire washing machine that can wash the floor surface of a car washing device with a water injection nozzle is disclosed, but this conventional example is a device for washing dirty tires of a vehicle, and does not spray water onto the body of a vehicle. It does not have a nozzle for ejecting water, and therefore its structure and operation and effects are different from the present invention. Furthermore, in JP-A-51-144072,
A wheel cleaning device for a large vehicle is disclosed, but although the conventional example is capable of cleaning the floor surface, it is also used exclusively for wheel cleaning, and its structure and operation and effects are different from the present invention.

In any case, these conventional examples do not disclose or suggest that the route of the water sprayed can be switched to be used for washing the body of a vehicle and for washing the floor surface of the vehicle.

The present invention has been made in order to eliminate the above-mentioned drawbacks of the prior art, and its purpose is to pump a car wash pump from a fountain pipe disposed on both longitudinal sides of a floor surface including a car wash room. By spraying high-pressure cleaning water supplied by the The purpose is to make cleaning easier and save labor. Another object of the present invention is to reduce equipment costs by allowing a car wash pump to be used for floor cleaning.

In short, the present invention provides a car wash room in which washing water is sprayed onto the vehicle while the vehicle is running on its own, a water tank for storing the washing water, and a fountain in the car wash room by pumping up the washing water from the water tank. A pump for supplying the pipe is disposed at a predetermined height from the floor on both sides in the longitudinal direction of the floor including the car wash room, so that the washing water is sprayed over the entire floor.
