DETAILED DESCRIPTION OF THE INVENTION A. OBJECTS OF THE INVENTION a. Field of Industrial Application The present invention relates to a unit cleaning system including a plurality of high-pressure injection type cleaning devices for cleaning vehicles and the like.

b. Conventional technology Conventional cleaning systems using high-pressure jet cleaning devices are generally either a single cleaning device arranged at a car wash, or a water tank and a detergent tank are combined into one and only the cleaning nozzle is installed at a car wash. Japanese Patent Application Laid-open No. 1986-98660 has been submitted for a car wash system for washing water, but this system has the disadvantage that when creating washing water, the concentration is uneven and concentrated detergent accumulates at the bottom of the tank. occurs.

In addition, the method of sucking up concentrated cleaning water using a siphon method, the amount sucked up at one time is not stable.

For example, if the liquid level in the concentrated wash water tank is low, more suction power is required to suck it up.

In other words, since the water pressure of the tap water is fixed, that is, the suction force is also fixed, the lower the liquid level is, the less concentrated cleaning water is sucked. As a result, the concentration of the cleaning water becomes non-uniform and unstable.

Further, since the amount of suction required to obtain a siphon effect is small, the amount of tap water cannot be increased in accordance with the dilution ratio, so there is a limit to the amount of cleaning water that can be produced.

In a car wash facility having multiple car wash nozzles, there may be a situation where there is a shortage of washing water.

In addition, boilers are commonly used to heat water in water storage tanks during the winter, but with continuous operation of water circulation pumps, there may be a problem in which the boiler is frequently turned on and off. .

In other words, if there is water in the water storage tank with a temperature close to the boiler thermostat's temperature setting, if the circulation pump continues to supply that water, the boiler's thermostat will naturally ignite because the water is below the setting. As soon as the temperature rises above the set temperature, an order is given to extinguish the fire.

However, as low-temperature water continues to flow in,
The usual method of simply connecting the boiler and water storage tank with a circulation pump is inappropriate, as the process of igniting the fire again and quickly extinguishing it is repeated in a short period of time.

Then, automatic water spraying was used to prevent equipment from freezing during severe cold weather, but
Methods such as No. 98660, which do not use a pump exclusively for water discharge, but instead use a circulating pump to circulate hot water, have the following drawbacks.

That is, since the car wash nozzle is usually routed far away from the car wash facility and is suspended from a high position by a nozzle boom, a certain amount of water supply pressure is required.

At the same time, since each position of the car wash nozzle is individually arranged in the car wash, the distance from the water storage tank is different, and the required water supply pressure also differs depending on the position of the car wash nozzle.

In other words, when trying to discharge water with the circulation pump,
Since the water supply pressure is higher on the car wash nozzle side, most of the water inevitably escapes to the water storage tank side where the pressure is lower. Even if some amount of water can be sent, the problem is that the water is only sent to the car wash nozzle near the water storage tank and does not flow to other areas.

c. Problems to be Solved by the Invention The present invention addresses these problems, stably and uniformly replenishes the mixing and creation of cleaning water, and also improves the boiler's efficiency when creating hot water in the water storage tank. The purpose of the present invention is to provide a washing system that enables smooth operation and that can reliably and evenly distribute water to each car wash nozzle to prevent freezing.

The liquids from the water tank and concentrated detergent tank are combined by a circulation pump, and the agitation action of the pump makes it possible to create thoroughly mixed washing water.The flow rate of the concentrated detergent and water can be adjusted using an adjustment valve. Since the suction force of the detergent replenishment pump is always constant, a large amount of washing water with a predetermined concentration can be produced.

The main body tank block has a dedicated water pump, and the amount and pressure of the water can be adjusted using the adjustment valve, which means that the amount of water supplied to cleaning nozzles with different installation distances can be the same at each location, and a dedicated pump can be used. Pumping water is an extremely safe water discharging system in the sense that the necessary pressure is always available and water is reliably discharged even in extremely cold weather.

The present invention is configured as described above, and has a high ability to automatically and uniformly produce washing water in large quantities, and at the same time, can be expected to always have a constant washing effect.

Controlling the circulation pump according to the water temperature in the water storage tank in terms of hot water production capacity not only improves the life and reliability of the boiler pump, but also reduces boiler fuel consumption by eliminating unnecessary ignition. This means that it can be used effectively.
