Abstract

PURPOSE:To make the equipment intensive and thereby reduce the equipment cost as well as to enhance the washing efficiency by constituting warm water high in pressure to be supplied to an automatic vehicle washing device and plural hand washing nozzles out of a high pressure warm water generator with a change-over valve operated. CONSTITUTION:In the case that washing is to be processed by a hand washing nozzle 41, when its operating end 4a1 is turned on, an input signal is transmitted to a control device 6, a high pressure pump is then operated with a command signal outputted to a high pressure warm water generator 1 from a control device 6. The control device 6 simultaneously directs a command signal to a change-over valve 2, so that warm water high in pressure is fed to the hand washing nozzles 41...4n with the vale changed over. By the way, when an automatic washing device 3 is in operation, a prohibition signal is directed to the change-over valve from the control device 6 based on the signal from a detecting means 5. Washing is kept on at the automatic washing device side with no change-over made to the portable washing nozzle side though the operating end 4a1 is turned on, operating the automatic washing device 3 is thereby kept on.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field The present invention relates to a system cleaning device that can efficiently clean a vehicle.

(2) Conventional technology Conventional automatic cleaning equipment that cleans the sides and bottom of vehicles is
For this purpose, a high-pressure hot water generator consisting of a boiler and a high-pressure pump is required, and the washing nozzle requires a high-pressure hot water generator for washing the vehicle.

(3) Problems to be Solved by the Invention However, the above-mentioned conventional cleaning devices each require a high-pressure hot water generator consisting of a boiler and a high-pressure pump, which increases equipment costs and makes it difficult to use either device. In some cases, the operating efficiency is lowered, and handling and maintenance become complicated.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks, and to provide a system cleaning device that consolidates and simplifies high-pressure hot water generators, distributes high-pressure hot water to locations of use in a timely manner, and improves cleaning efficiency.

(4) Means for Solving the Problems In order to achieve the above object, the present invention provides a high-pressure hot water generator and a high-pressure hot water generated by the high-pressure hot water generator to be used in an automatic vehicle washing device or a plurality of hand washing machines. A switching valve that switches to the nozzle, an operation terminal attached to each of these cleaning nozzles,
a detection means for detecting whether the automatic vehicle washing device is in operation; and a command signal for operating the high-pressure hot water generator and switching the switching valve to the washing nozzle side when an ON operation is performed at any of the operating terminals. and a prohibition signal that prohibits switching of the switching valve to the cleaning nozzle side despite the ON operation when it is determined that the vehicle automatic cleaning device is in operation based on the signal from the detection means. It is characterized by comprising a control device that performs the following operations.

(5) Function When using a washing nozzle for hand washing, when the operating terminal attached to the nozzle is turned ON, the high pressure hot water generator is operated by a command signal from the control device and the switching valve is switched to the washing nozzle side. High-pressure hot water flows into the cleaning nozzle, allowing you to manually clean the vehicle.

However, when the automatic cleaning device is in operation, even if the operation terminal is turned on, the control device generates a prohibition signal to the switching valve based on the signal from the detection means, and the switching valve holds the automatic cleaning device side and turns the automatic cleaning device off. The operation of the cleaning equipment is controlled by the emperor, and high-pressure hot water does not flow into the portable cleaning nozzle side.

(6) Examples Embodiments of the present invention will be described below with reference to the drawings.

(1) indicates a high-pressure hot water generator;
) consists of, for example, a multi-disk type once-through boiler hot water tank and a double ceramic plunger pump, and (2)
indicates a switching valve for branching and switching the high-pressure hot water generated by the high-pressure hot water generator (1), and the switching valve (2) is composed of, for example, a three-boat solenoid valve.

(3) indicates a vehicle automatic cleaning device;
) consists of an automatic lower cleaning device or side cleaning device, etc.
Also, (4-)...(4n) indicates a washing nozzle for hand washing,
These hand washing nozzles (4,)... (4n) have a stop gun mechanism, and the hand washing nozzles (4,)...
- Operation terminals (4a+)...(4an) are attached to (4n).

(5) indicates a detection means, and the detection means (5) consists of, for example, a flow switch interposed in a pipe (7a) connecting between the switching valve (2) and the automatic cleaning device (3),
During the operation of the automatic cleaning device (3), the pipe (7a
), the flow of this high-pressure hot water is detected and it is known that the automatic cleaning device (3) is in operation.

(6) indicates a control device, and the control device (6) inputs signals from the operation terminal (4aρ...(4am) and the detection means (5), and switches the high-pressure hot water generator (1) and A command signal is output to the valve (2) to perform the control operation described later.

In addition, (7b) is a pipe connecting the high pressure hot water generator (1) and the switching valve (2), and (7c) is the pipe connecting the switching valve (2).
) and the cleaning nozzles (4I)...(4n) are shown.

In the above configuration 2, for example, when cleaning is performed using a hand washing nozzle (4θ), when the operating terminal (4a#) of the hand washing nozzle (4I) is turned on, an input signal is sent to the control device (6), and the control From the device (6) to the high pressure hot water generator (
1) to operate the high pressure pump of the generator (1).

Note that the boiler of the high-pressure hot water generator (1) is activated in advance and hot water at a predetermined temperature is stored by a temperature controller. At the same time, a command signal is generated from the control device (6) to the switching valve (2).

The switching valve (2) is switched to the hand washing nozzle side to send high pressure hot water to the hand washing nozzles (4a)...(4n). At this time, the hand washing nozzle (4θ...(4
n) has a stop gun mechanism, so it can be washed using a desired hand washing nozzle (4 hot). However, when the automatic cleaning device (3) is operating, the detection means (5)
The control device (6) receives a signal from the switching valve (2).
Even though the operation terminal (4aθ) is ON, the switching valve (2) does not switch to the portable cleaning nozzle side but maintains the automatic cleaning device side, and thus the automatic cleaning device (3 ) continues to operate.In other words, the operation of the automatic washing device (3) is given priority over the hand washing nozzles (4I)...(4n).

Next, when the operating terminal (4a) is turned off, a command signal is sent from the control device (6) to the switching valve (2), which switches the switching valve (2) from the hand washing nozzle side to the automatic washing device side. At the same time, the control device (6) outputs a command signal to the high-pressure hot water generator (1) to stop the operation of the high-pressure pump of the generator (1).

In the above case, the hand washing nozzle (4θ example was explained, but other hand washing nozzles (1, 1)...(4n)
The same applies to the case of .

(7) Effects of the Invention As described above, according to the present invention, it is possible to supply high-pressure hot water to the vehicle automatic washing device and a plurality of hand-washing nozzles from one common high-pressure hot water generator by switching the switching valve.
Equipment can be consolidated and equipment costs can be reduced, and when the automatic cleaning equipment is in operation, the operation of the automatic cleaning equipment is preferentially interrupted due to a signal from the detection means despite the ON signal from the operating terminal. This has the effect of increasing the efficiency of cleaning.
