Description

Car Washer Utilizing Steam and Warm Water}

The present invention relates to a car wash for both steam and hot water, and more particularly, by maintaining the water in the boiler at a level within a certain range, it is possible to effectively prevent damage due to overheating, and to reduce downtime. Relates to a steam and hot water car wash.

Typically, in the car wash, the car is washed by spraying water at a high pressure to remove dirt, etc. from the car body. The car washing method has a problem in that a large amount of water is consumed and a large amount of waste water is generated to cause environmental pollution.

Therefore, in recent years, a steam car wash that can be washed with a small amount of water using steam has been developed and used. Since such a steam car wash is difficult to clean a lot of dirty parts such as wheel housings, Steam and hot water combined wash for washing with hot water has been developed by myself and disclosed in Utility Model Registration No. 0195666.

The combined steam and hot water washer is a boiler that generates steam by heating water by a burner, a steam tank connected to the boiler to store and supply steam, a water tank connected to the steam tank, and the steam It is composed of a nozzle connected to the tank and the water tank to selectively discharge steam or hot water. Therefore, such a combined steam and hot water car wash has an advantage of easily removing old times or grease by generating high temperature and high pressure steam and hot water with a small amount of water.

However, since the amount of water stored in the boiler is limited due to the limited amount of water stored in the boiler, such water and water are often insufficient or exhausted during use. And there is a problem such as causing a safety accident. In addition, the car wash should be supplied frequently because the water in the boiler does not maintain a constant level as the car washes, and in this case, water must be frequently supplied. In this case, the water is heated to a predetermined temperature to generate steam. There is a problem such as lowering the work efficiency, such as having to stop. In addition, since the combined use of steam and hot water is not operated in connection with the water pipe because it is operated by the pressure of steam, it is separated and used, so when water stored in the water tank other than the boiler is exhausted, It is inconvenient to use it, such as water supply, there is a problem that increases downtime due to water supply.

The present invention has been proposed in view of the above-described problems, and an object of the present invention is to effectively prevent damage due to overheating by reducing the water level inside a boiler within a certain range and reducing downtime. To provide a steam and hot water car wash that can give.

According to the present invention, a boiler 10 for heating steam to generate steam, a steam tank 20 for storing steam generated by being connected to the boiler 10, and a steam tank 20 connected to the steam tank 20 In the steam car wash comprising a water tank 30 to maintain the water therein at a high temperature and high pressure, the boiler 10, the steam tank 20 and the water tank 30 is a predetermined tube 12 , 32, 40 are connected in the form of a closed loop, the tubular body 40 between the water tank 30 and the boiler 10 is provided with a check valve 50, the boiler 10 as the car wash When the water level of the lower, the water and the water tank 30 is provided with a steam and hot water combined wash, characterized in that configured to automatically supply water to the boiler (10).

According to another feature of the present invention, the water supply tank 60 is connected to the water tank 30 to supply water to the water tank 30 and the boiler 10, characterized in that the steam is further provided And a hot water car wash.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 1 shows an embodiment of a steam and hot water combined wash according to the present invention. Referring to this, the combined steam and hot water washer boiler 10, the steam tank 20 connected to the e-boiler 10, the water tank 30 connected to the steam tank 20, the boiler 10 And a tubular body 40 for connecting the water tank 30, a check valve 50 installed in the tubular body 40, and a water supply tank 60 connected to the water tank 30.

The boiler 10 is configured to generate steam by heating the water inside by the burner 2 connected to the gas cylinder 1 on the bottom thereof, and configured to supply the generated steam to the steam tank 20. The steam tank 20 is to store the steam generated by being connected to the boiler 10, in addition to the conventional pressure gauge 21 and the safety valve 22, a separate thermometer 23 is further installed. Such a thermometer 25 is to ensure that even if the pressure gauge 27 and the safety valve 28 breaks down during use, the user is notified of overheating of the boiler 10 or the resulting vapor pressure, so that safety measures can be taken. In addition, the boiler 10, the steam tank 20 and the water tank 30 are each connected in a closed loop shape by a predetermined tube (12, 32, 40) so that the pressure is maintained the same, the water tank 30 is mounted such that the water surface is adapted to or above the desired water level of the boiler 10. Therefore, as the water of the boiler 10 decreases as the car washes, water stored in the water tank 30 is automatically supplied to the boiler 10 so that the water surface of the boiler 10 is maintained within a predetermined range.

The check valve 50 is installed in the tubular body 40 connecting the boiler 10 and the water tank 30 to prevent the water supplied from the water tank 30 to the boiler 10 from flowing back. . The water supply tank 40 is connected to the water tank 30 by the water supply pipe 34, the water supply pipe 34 is provided with a valve 36 to open the valve 36, if necessary, the water It is configured to supply to the water tank 30, to facilitate the use of water replenishment work in the water tank (30).

According to the steam and hot water combined wash configured as described above, when the steam generated in the boiler 10 is stored in the steam tank 20 and the valve 28 of the hose 26 connected to the steam tank 20 is opened, Steam is ejected to wet the surface of the vehicle, and the vehicle can be washed using a mop. When the valve 38 of the hose 37 connected to the water tank 30 is opened, high temperature and high pressure water is discharged. Therefore, it is possible to wash parts with a lot of dirt or oil, such as wheels or wheel housings of vehicles. At this time, even when the water of the boiler 10 is reduced according to the washing of the combined steam and hot water, the water stored in the water tank 30 is automatically supplied to maintain the water level within a certain range, the lack of water or exhaustion This prevents overheating of the boiler, which prevents breakdowns and safety accidents.It also significantly reduces the downtime required to stop operation until steam is generated by reheating the supplied water as before. Can be. In addition, the combined use of the steam and hot water washer when the water in the water tank shortage can be easily supplied by opening the valve of the water supply pipe can be convenient to use and downtime due to water supply can be reduced.

As described above, according to the present invention, the combined use of the steam and hot water is prevented from overheating of the boiler due to lack of water or exhaustion, so that failure or danger can be eliminated, and the downtime can be significantly reduced, thereby improving work efficiency. This can be improved, and can be easily watered, there is an advantage of ease of use as well as reducing downtime due to water supply.
