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 axles 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 designed to improve

Conventionally, washing large vehicles has relied on hand washing, which requires two to four hours to wash one car because the washing area is larger and the car is more dirty than a passenger 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 washing equipment for small axles, such as those installed in the refueling θ [neckline], in which the main washing equipment is moved while the vehicle is stopped, is too large for large vehicles, so it is not practical. The current situation is that it is advantageous. Therefore, as a car wash device for such a large-scale vehicle, the car wash device is kept stationary, and the vehicle is allowed to run inside it by itself.
A car washing device is considered that sprays high-pressure washing water onto the vehicle and can wash the vehicle in a short time.

However, large vehicles with trunks often drive on rough roads, so
The floor surface is heavily contaminated with mud and oil, and since many vehicles are washed continuously in a car wash room, the mud, oil, etc. that fall off the vehicles become sludge and accumulate all over the floor surface. Previously, this had to be cleaned manually by pouring water from a high-pressure pump hose, or by using a brush, mop, etc. For this reason, there is a drawback that cleaning the floor surface is difficult and takes a long time.

The present invention has been made in order to eliminate the drawbacks of the prior art described above, 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 the pressure washing water supplied by the machine, the sludge made of mud and oil accumulated on the floor can be washed away without manual intervention and in a short period of time. The purpose is to facilitate floor cleaning and save labor. Another purpose is to install a car wash pump on the floor.
The aim is to reduce equipment costs by making it possible to switch between cleaning and 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 storage tank for storing the washing water, and a water tank for pumping up the washing water from the water storage tank. A pump for supplying water to the fountain pipe is disposed on both longitudinal sides of the floor surface including the car wash room at a predetermined height from the floor surface so that the wash water is sprayed over the entire floor surface. and a floor washing fountain pipe, and the floor washing fountain pipe is connected to the pump so that the pump can be used for switching to floor washing.
