Description

Steam generator for car wash {steam generating apparatus for car-washing}

The present invention relates to an automotive steam car washing device that does not use washing water, mop, etc. More specifically, the steam and the cleaning agent are selected while improving the steam generation speed by the supply water mixing means in the air and water mixed state Or it is possible to use a mixture, and by improving the structure of the steam chamber for a car wash steam generator to improve the thermal efficiency.

In general, the washing of the car is washed by mechanical automatic car wash and high-pressure sprayed washing water in the car wash equipped with the washing machine, and in general households, the car is washed by using a mop or a sponge.

The conventional car wash method is to finish the car wash by spraying high-pressure water on the surface of the vehicle to wash the dust or various foreign matter adhered to the surface, and then using a varnish to polish the car, at this time The amount of washing water used in the house is more than a day's consumption in a general household, so the waste of energy is very serious.

In addition, when washing the car in a restaurant or residential area, there is a problem that the passing pedestrian is damaged, there is a problem that the unpurified washing water is discarded as it is causing environmental pollution.

In addition, when washing in winter, the surface of the vehicle is often frozen because the temperature is low, there is a problem that is very dangerous for vehicles and pedestrians, such as freezing the surrounding road by the flowing washing water.

Therefore, as in Utility Model Registration Application No. 98-877 and Utility Model Registration Application No. 99-5819 issued by the applicant of the present invention, a high temperature heating plate is provided with steam generating means, water supply means, heating means and injection means. By spraying water on the water, steam is generated, and high pressure water vapor is discharged to the outside through the injection nozzle, so that the car can be washed with only a small amount of washing water, and it is easy to carry and can be used for home use. The generator has been put out.

However, since the steam generator is always sprayed with the same pressure and the amount of steam, there is a problem that can not be applied variously depending on the type of vehicle or the strength of the car wash, because the manual pump must be operated frequently during the car wash time There is a problem that the pumping work has to be long and often come to the steam generator, there is a problem that can not wash the inside of the vehicle and the wheels of the vehicle.

Therefore, as in 2000 Patent Application No. 43447 issued by the applicant of the present invention, the amount of high pressure steam injected can be arbitrarily set and adjusted, and water is automatically supplied by an air pump that is automatically operated by electrical operation. Since the steam is continuously sprayed without a separate operation by the supply, the invention has provided a method for generating a car washing steam and the device that can be washed and cleaned not only the outside of the vehicle but also the interior and the wheel of the vehicle.

However, the above-described steam generator is capable of continuously generating and discharging steam, while being very convenient and easy to use, while it is impossible to control the cleaning agent that is mixed with steam and injected, and the thermal efficiency is low. The above fuel is required, and even if the flame is extinguished by the wind, the gas is continuously leaked, which is a very dangerous problem.

In addition, even in the case of a shortage of feed water or an abnormality in the pump, the heating plate was continuously heated, causing fire and damage to the apparatus.

The present invention has been made to eliminate the problems described above, by installing a separate pump and valve in the conventional car wash steam generator to control the supply amount and supply of the cleaning agent, the air and water by the compressor and pump In the mixed state to be injected into the steam chamber, the steam chamber to form a plurality of through holes, the ignition device and the steam chamber is equipped with safety means and detection sensors, respectively,

It is possible to wash the car more conveniently by controlling the use of the cleaning agent and its amount easily, while generating a large amount of steam with only a small amount of fuel, which saves fuel and enables automatic ignition when extinguishing by wind. It is an object of the present invention to provide a car wash steam generating device that enables safer use by blocking the overheating of the steam chamber and the liquefaction of steam by the detection sensor mounted on the sensor.

The steam chamber 3 is equipped with a temperature sensor 17 and a pressure sensor 18, and the burner 4 is equipped with an auto ignition device 19 and an ignition safety device 20, and gas is burned in the burner 4. The gas pipe 21 to be supplied is formed by coupling the solenoid valve 22.

In addition, a plurality of heat dissipation pipes 23, 23 'are vertically formed in the steam chamber 3, and the contact area of the flame provided from the burner 4 at the lower side is increased so that the thermal efficiency is improved.

A high quality tubular body 24 is formed on the outer periphery of the steam chamber 3, and the tubular tube 24 is communicated with the steam chamber 3 by a plurality of connecting tubes 25 and 25 ′ formed at the lower part of the tubular body 24. Steam pipe 5 is connected to the upper one side of the tubular body 24, the burner (4) flame in the lower part of the steam chamber 3 rises and falls along the shape of the tubular body 24 may be configured to improve the thermal efficiency And

The propeller 26 which rotates at high speed by the motor 29 is built in the above-mentioned mixer 6, and the feed water and air provided from the water tank 1 and the compressor 11 are mixed, and it supplies it. It is configured to be discharged into the water pipe (2),

The porous body 27 may be built in one side of the mixer 6 so that the air pipe 28 by the compressor 11 is positioned on the side in which the porous body 27 is embedded.

In the figure, reference numeral 30 denotes a controller.

When described in more detail by the accompanying drawings the operation of the present invention car wash steam generator as described above are as follows.

First, a schematic operation of the steam generator according to the present invention will be described. When the power is applied to the device by using the controller 30 by the user, the solenoid valve 22 of the gas pipe 21 is opened and the gas is burned to the burner 4. Is supplied, and the automatic ignition device 19 operates to ignite the gas at the same time as the gas is supplied.

The ignition of this gas is to heat the steam chamber 3 above the burner 4, and when the steam chamber 3 is sufficiently heated and the temperature sensor 17 recognizes this, the water tank 1 and the compressor ( 11) while operating, it mixes air and water together and sends it to the steam chamber (3) through the feed water pipe (2).

Therefore, the supply water injected into the steam chamber 3 heated to a high temperature is injected into the steam chamber 3 and vaporized and expands with steam, and the steam is expanded by the expansion pressure of the vaporized steam. Accordingly, it is sprayed to the outside through a separate nozzle (not shown in the figure).

In addition, during the initial car wash, since the surface of the vehicle can be washed more cleanly, as well as steam, the cleaning agent must be sprayed together. The vehicle surface is easily and cleanly washed by being sprayed, and after the initial washing is finished, the opening and closing valve 13 of the cleaning pipe 12 is closed to wash the surface of the vehicle by steam consisting of pure water. And so on.

Such, the steam generator of the present invention is very easy to use, but only a small amount of fuel and water is able to clean the vehicle more clean.

In addition, the automatic ignition device 19 for igniting the burner (4) is to ignite the automatic spark again when the ignition spark is turned off by wind or other drafts to prevent the steam is stopped or gas leaks during the car wash, If the wind continues to ignite, the ignition is automatically stopped and the solenoid valve 22 of the gas pipe 21 is closed.

In addition, the ignition safety device 20 mounted on one side of the aforementioned auto ignition device 19 detects whether the burner 4 is completely ignited by the auto ignition device 19, and is caused by a normal thermocouple. .

In addition, the temperature sensor 17 and the pressure sensor 18 connected to the steam chamber 3 measure the temperature and the pressure, respectively. For example, when the temperature inside the steam chamber 3 reaches a certain temperature or more, water is not supplied. If the temperature rises above a certain temperature, the power of the device is automatically stopped to prevent fire and damage to the device due to overheating of the steam chamber (3).

The pressure sensor 18 is set by dividing the increase in pressure due to the generation of steam and the decrease in pressure due to the use of steam into a maximum limit width and a minimum limit width, and measure the time of descending from the highest pressure to the minimum pressure for a predetermined time or more. If time is taken, the steam is not used and the burner 4 is turned on even at the minimum pressure, but the water is not supplied but only preheated to control the steam to be generated at a constant pressure. (4) is turned on to measure the time at which the maximum pressure is reached. If the burner (4) continues to operate for a certain time or more, the handle is recognized as using steam and the water supply pump (9) is operated so that the steam at a constant pressure is always present. Is to control this to occur.

In addition, the water level sensor (7) built in the water tank (1) is automatically notified to the user by a warning sound or a light emitting lamp when the water drops during car wash, the operation of the device after a certain time warning sound To stop,

The water level sensor 14 embedded in the cleaning tank 15 also has the same function as described above.

Hereinafter, the operation of each main part in more detail,

First, as shown in FIG. 2, the flame of the burner 4 located below the steam chamber 3 primarily directly heats the bottom bottom of the steam chamber 3, and the bottom surface of the steam chamber 3. At the same time as heating the flame is introduced into a plurality of heat dissipation pipes (23, 23 ').

Therefore, since the heat dissipation pipes 23 and 23 'are simultaneously heated together with the bottom surface of the steam chamber 3, the steam chamber 3 is heated more rapidly than before, and the supply water is injected into the steam chamber 3 Even if the thermal energy is lost by vaporization, the steam chamber 3 is heated faster than before, so that the amount of steam generated is further increased.

In addition, as shown in FIG. 3, the tubular body 24 is formed on the outer circumference of the steam chamber 3, and the feed water pipe 2 is introduced from the upper portion thereof to be connected to the steam chamber 3. In the lower part of the 24, by connecting the steam chamber 3 and the tube 24 to each other by a plurality of radially formed connecting tubes (25, 25 '),

The hot heat discharged from the lower burner 4 of the steam chamber 3 rises along the inner wall of the tubular body 24 and flows back from the upper part so as to travel outside the tubular body 24. Of course, since it has the effect of heating the inner and outer walls of the tube 24 at the same time, it will have an increased steam generation amount.

In addition, the mixer 6 for mixing water and air as shown in FIG. 4 has a propeller 26 embedded therein, and when it is rotated at a high speed by using a separate motor 29, the compressor 11 and Air and water are mixed while the air flowing into the air pipe 28 through the regulator 10 and the water provided from the pump 9 of the water tank 1 are crushed and mixed by the rotational force of the propeller 26. When injected into the steam chamber (3) through the furnace supply water pipe (2), the heating rate of the water is improved faster by the air having a faster heating rate than the water, so that the vaporization of the water is made faster.

In addition, as illustrated in FIG. 5, the air introduced through the air pipe 28 is introduced into the porous body 27 by not including a separate mechanical device, but by embedding the porous body 27 inside the mixer 6. By changing it into a small air bubble form by sending it to the steam chamber (3) through the water supply pipe (2) with the water will be provided with a richer steam because it promotes the vaporization action as described above.

The car wash steam generator of the present invention as described above makes it easier to wash the car by controlling the use of the cleaning agent and the amount thereof, while generating a large amount of steam with only a small amount of fuel, thereby reducing the fuel and extinguishing by wind. At the time of the automatic ignition is possible, by the detection sensor mounted in the steam chamber is to prevent the overheating of the steam chamber and the liquefaction of the steam there is an effect that can be used more safely.
