Description

Functional exhaust pipe, manufacturing method thereof, and high-pressure steam car wash having the functional exhaust pipe {Function vent pipe and manufacturing therefor, and wash appratus for automobile using steam having the same}

The present invention relates to a functional exhaust pipe, a method for manufacturing the same, and a high-pressure steam car washer having the functional exhaust pipe, and more specifically, to a shopping mall or apartment building because noise generated when exhaust gas is discharged can be significantly reduced compared to the prior art. A functional exhaust pipe capable of easily performing indoor car washing operations such as an underground parking lot without any particular problem, and a method for manufacturing the same, and a high-pressure steam car washing machine having the functional exhaust pipe.

In order to keep the exterior of the vehicle clean, it is common to wash the car using tools such as a bucket and a mop.

However, if the car is washed in the classic way using water and a mop, the pressure of the water sprayed on the vehicle is weak, so it may not be able to cleanly wipe off grease or dirt on the wheels or pandas of the vehicle.

Accordingly, steam car washing using steam is widely used in order to clean the car while reducing the use of water.

A steam car wash is a device that generates steam discharged at high pressure to protect the vehicle paint film while removing contaminants and foreign substances from the vehicle paint film.

In particular, as a mobile steam car wash is recently developed as shown in FIG. 1 , a travel service related to car washing can be received.

Referring to FIG. 1 , a conventional mobile steam car wash includes a frame 6 , a steam generator 10 installed on the frame 6 to boil water to generate steam, and a steam generator connected to the steam generator 10 . and a steam tank 20 having a steam outlet 26 for storing the steam generated from (10) and discharging the steam stored therein on one side, and a water tank 40 connected to the steam tank, the water tank ( 40) is formed on one side of the pressurized water outlet 44 for discharging water, so that the water pressurized by the vapor pressure of the steam tank 20 can be discharged at a high pressure.

Meanwhile, although not illustrated in FIG. 1 , an exhaust pipe for discharging exhaust gas generated when steam is generated is provided in a conventional mobile steam car wash as shown in FIG. 1 .

However, since the exhaust pipe applied to the conventional mobile steam car wash including FIG. 1 is in the form of a simple pipe having a circular cross-section, there is a problem in that when the exhaust gas is discharged, a large noise is generated. Of course, there is a serious problem of smell as well as noise.

Therefore, if a mobile steam car wash equipped with such an exhaust pipe is moved to, for example, a shopping mall or an underground parking lot of an apartment, and then an indoor car washing operation is performed on site, the indoor car washing operation is inevitably difficult due to noise, and further, various civil complaints are raised. Considering that it can be done, technology development is needed to solve this problem.

A burner, a moisture content control valve, a water level control sensor, a pressure gauge, a pressure switch, a pressure valve, etc. to be attached hereto can be attached to products widely used in conventional steam generators.

High-temperature air is introduced into the body through an inlet 216 from a burner (not shown). The introduced high-temperature air is discharged to the outside through the functional exhaust pipe 240 opposite the inlet 216 . The high-temperature air causes heat exchange while passing through the inside of the body to change water into steam.

The steam generator 210 has water inlet (220a, 220b), steam outlet (222a, 222b), water amount control valve attachment (224a, 224b), water level control sensor attachment hole (226a) symmetrically on both sides with respect to the center. , 226b), and the pressure gauge attachment ports 228a and 228b are each independently attached.

Water introduced through each water inlet (220a, 220b) is changed to steam by high-temperature air, and then is discharged through each of the steam outlets (222a, 222b).

A water amount control valve is attached to the water amount control valve attachment port (224a, 224b). The moisture content control valve performs a function of adjusting the moisture content included in the steam. Then, the water level control sensor is attached to the water level control sensor attachment hole (226a, 226b). The water level control sensor closes the water inlets 220a and 220b when the amount of water introduced is greater than or equal to a certain amount, and opens the water inlets 220a and 220b when the amount is less than a certain amount to control the amount of water introduced into the body.

A pressure gauge, a pressure switch, and a safety valve are attached to the pressure gauge attachment ports 228a and 228b. The pressure gauge displays the internal steam pressure, the pressure switch stops the burner when the internal steam pressure exceeds a set value, and the safety valve opens the pressure switch hole when the internal pressure exceeds a certain value. It serves to release the pressure to the outside.

Referring to FIG. 8 , the steam generator of this embodiment is manufactured in a dual structure including an inner wall 212 and an outer wall 214 .

Steam can be generated in two parts.

That is, the water 234 through each of the water inlets 220a and 220b on both sides is independently changed to the steam 236 by the high-temperature air heat, and then is discharged to the outside through the respective steam outlets.

One steam generator 210 is divided into two parts by the upper and lower partition walls 230a and 230b, so that the two parts can generate steam independently of each other without being influenced by each other. As such, since steam can be generated independently of each other, by forming only two steam outlets, it is possible to solve the problem that the pressure of steam is lowered.

Referring to FIG. 9 , the high-temperature air introduced through the inlet is discharged to the outside through the functional exhaust pipe 240 through the inner wall. The hot air changes water into steam through heat exchange inside the inner wall. A plurality of plates 232 are installed for guiding the high temperature air so that heat exchange occurs smoothly by increasing the time the high temperature air stays.

On the other hand, even in the case of this embodiment, the functional exhaust pipe 240 includes a straight exhaust line 241 , a curved exhaust line 242 , and a noise reduction module 243 . Their structures and functions are the same as those of the above-described embodiment.
