Description

[Detailed Description of the Invention] This invention relates to a spray cleaning device that discharges cleaning water toward an object to be cleaned, such as an automobile, to perform cleaning.

Generally, this type of equipment cleans by using a high-pressure spray that is directed at the object being cleaned, but although this alone can remove dirt such as sand and mud, it does not remove dirt such as oil or water scale. It was difficult to remove the caked-on dirt. Therefore, it is necessary to manually remove the remaining dirt locally with a brush or cloth after spraying, and there has been a desire for a device that can clean the spray without leaving any residue.

This invention was made in response to these problems, and aims to provide a device that can selectively use spray cleaning and brush cleaning depending on the type of dirt, and achieves effective cleaning without leaving any residue.

Specific examples thereof will be explained below based on the drawings.

There is. The water storage tank 2 receives water from a water source 7 such as a tap via a ball tap 8 and stores water at a constant level.
It is connected to the suction side of the pump 6 through a conduit 9 . 10 is a solenoid valve provided in the pipe line 9.

The detergent water tank 4 is equipped with a hot water heater 11, a liquid level sensor 13 consisting of a thermistor 12 for controlling energization of the heater 11, and a diaphragm switch.
The detergent solution in the detergent tank 3 is diluted to the concentration used, and the detergent water is heated to an appropriate temperature and stored. The detergent water in the detergent water tank 4 is mixed using a solenoid valve 14 that is opened and closed by a signal from the liquid level sensor 13, and a suction nozzle that communicates with the detergent tank 3 through a pipe 15 to the internal diffuser. It is supplied by a line 17 with a vessel 16. That is, when the liquid level in the detergent water tank 4 falls below a predetermined level, the solenoid valve 14 is opened to introduce water from the water source 7, and the mixer 1

When waxing, the solenoid valve 26 is opened to direct some of the water discharged from the pump into the conduit 24. This water and wax liquid are mixed in a mixer 25 and supplied to the suction side of the pump 6. Solenoid valve 26
When opened, part of the discharge pressure of the pump 6 is connected to the pipe 2.
4 to the suction side of the pump 6, and is considerably reduced. Therefore, this solenoid valve 26 can be used not only when applying wax, but also as a pressure reducing means when it is desired to obtain a low-pressure spray. The regulating valve 27 regulates the flow rate of the pipe line 24, thereby regulating the spray discharge pressure. Reference numeral 28 denotes a flow control valve provided in the pipe line 23, which controls the wax mixture concentration in the mixer 25. 29 is a solenoid valve provided in the conduit 23.

29 and 34 are opened and wax mixed water is sprayed at low pressure to perform waxing (3-4), and finally, solenoid valves 10, 26 and 34 are opened and water is sprayed at low pressure to wash away excess wax.
(3-5) As mentioned above, in spray cleaning, the first nozzle 3
0 can be used for cleaning or waxing by spray only.

As mentioned above, in spray cleaning, the first nozzle 3
0 can be used for cleaning or waxing by spray only.

In "brush cleaning", (1) Water washing course: The pump 6 is driven and the solenoid valve 1 is
0,26,35, the second nozzle 31
Water is sprayed at a lower pressure to enable brush cleaning using the brush 36 of the second nozzle 31 for a certain period of time. (1-1) (2) Detergent course: First, open the solenoid valves 10, 26, and 35 and perform brush cleaning with water (2-1).
Next, the solenoid valves 19, 26, 35 are opened to perform brush cleaning with detergent water (2-2), and finally, the solenoid valves 10, 26, 35 are opened again to perform brushing with water for rinsing. (2-3) (3) Wax course: Same as the detergent course above,
After cleaning the brushes with water (3-1), cleaning the brushes with detergent water (3-2), and cleaning the brushes with water (3-3), the solenoid valves 10, 26,

(3-5) As described above, in combination cleaning, it is possible to perform a combination of spray cleaning and brush cleaning by using the first and second nozzles appropriately, and as mentioned above, high-pressure spray cleaning is first performed. Sand of the object to be cleaned
If you wash the brush after removing mud, etc., you can brush it with sand and mud still on it.
The high cleaning effect of brush cleaning can be fully demonstrated without causing small scratches on the cleaning surface. In addition, in this combination cleaning, it is necessary to switch the first nozzle 30 and the second nozzle 31, but the notification means 56 may output a voice to instruct the nozzle to be replaced, and a holder (not shown) for each nozzle may be used. ) is provided with a nozzle detection switch or the like to confirm whether the nozzle has been replaced before proceeding to the next process, thereby making it possible to prevent erroneous users.

This invention is constructed as described above, and includes a water pressure switching means that switches the discharge pressure of cleaning water to at least two levels, high pressure and low pressure, a first nozzle device that mainly discharges high-pressure water and performs spray cleaning, and a cleaning brush. Since a second nozzle device is provided that mainly discharges low-pressure water to perform brush cleaning, it is possible to perform brush cleaning in addition to conventional spray cleaning, and remove build-up that cannot be removed with spray cleaning. By using a brush in combination, dirt can be easily removed, resulting in a high cleaning effect. Furthermore, when cleaning the brushes, the discharge pressure of the cleaning water is switched to be lowered and sprayed, so there is no inconvenience such as difficulty in brushing due to high reaction force from the object to be cleaned due to high-pressure spray, and smooth brushing can be achieved. In addition, the first and second nozzles can perform spray cleaning and brush cleaning, respectively, so each can perform a wide range of cleaning to suit the application, and by combining the two, it is possible to achieve high-quality cleaning that combines the advantages of both. Become.
