That is, the third internal space 14c having the above-described configuration corresponds to the other side portion of the internal space 14, and the precipitated and filtered rainwater flowing in the second internal space 14b flows and finally precipitates, So that the foreign matter contained in the exhaust gas is filtered.

As a result, rainwater contained in any one of the inner spaces (14) 14 may be prevented from being pushed into any one of the inner spaces 14 by the water pressure generated due to the difference in the amount of the rainwater received in the inner spaces 14.

In addition, the third internal space 14c is further provided with water level sensors 21a and 21b for sensing the level of the rainwater filtered by the third precipitation contained in the third internal space 14c, and the rainwater discharge port 13 The drain pump 40 connected to the drainage pump 40 may be configured to control the discharge of the rainwater filtered through the tertiary precipitation using the water level information sensed by the water level sensing sensors 21a and 21b.

That is, at least one of the water level sensors 21a and 21b is disposed at a predetermined portion of the third internal space 14c to sense the level of the rainwater filtered through the third settling contained in the third internal space 14c. At this time, The water level sensors 21a and 21b may be configured to continuously detect the level of the rainwater contained in the third internal space 14c or may be configured to detect only the low water level and the maximum water level of the rainwater.

As shown in FIG. 5, the water level sensors 21a and 21b include a first water level sensor 21a for sensing the low water level and a first water level sensor 21b for sensing the low water level, And a second water level sensor 21b for sensing the water level.

That is, the upper portion of the first level detecting sensor 21a is fixedly fastened to a certain portion of the third inner space 14c, and the lower portion of the lower portion extending downward from the upper portion is fixed to a predetermined level of the third inner space 14c The first level sensor 21a may be mounted on the lower end of the first guide rod 22a positioned on the first guide rod 22a and the second level sensor 21b may be mounted on the lower surface of the first guide rod 22a, And the second water level detection sensor 21b is mounted on the lower end of the second guide rod 22b having a shorter length.

The drain pump 40 is connected to a piping connected to the rainwater discharge port 13 to discharge the rainwater discharged from the rainwater discharge port 13 through the third precipitation filtered rainwater (hereinafter referred to as "purified water" And is operated by using the level information generated by the level sensors 21a and 21b, the first level sensor 21a and the second level sensor 21b.

At this time, low-level information is generated in the level sensors 21a and 21b (first level sensor 21a), and when the low-level information is transmitted to the controller, the controller generates stop information of the drain pump 40 The discharge pump is stopped to stop the discharge of the purified water in the third internal space 14c.

When the rainwater level of the third internal space 14c does not generate the low water level information, that is, when the rainwater level of the third internal space 14c is higher than the predetermined low water level, the drain pump 40 continuously So that the purified water contained in the third internal space 14c is continuously pumped to the outside of the main body 10.

When excessively large amount of rainwater is received in the third internal space 14c, that is, when the highest level information is generated in the level sensors 21a and 21b (the second level sensor 21b) The pump 40 can pump the purified water more quickly and discharge the rainwater contained in the third internal space 14c to the outside of the main body 10 at a high speed.

[0031] As shown in FIG.

That is, when the amount of precipitation is excessively large, the water level sensor 21a or 21b (the second water level sensing) is excessively accommodated in the third internal space 14c corresponding to the final internal space 14 of the internal space 14. [ The sensor 21b generates the highest level information and forcibly discharges the rainwater contained in the entire inner space 14, thereby ensuring the cleanability of the rainwater purified in the rainwater purifier according to the present invention.

Specifically, when excessively large amount of rainwater flows into the inner space 14 of the main body 10, the rainwater flow rate in the inner space 14 becomes excessively high, and as a result, the precipitation filtration of the rainwater in the inner space 14 The time is shortened, and the ability to remove foreign matter contained in rainwater is reduced. The maximum water level information generated by the water level sensors 21a and 21b (the second water level sensor 21b) having the above-described configuration is transmitted to the controller so that the solenoid valves 17a-1, 17a-2, and 17a-3 are opened by the operation signal, the first internal space 14a, the second internal space 14a, The rainwater contained in the inner space 14b and the third inner space 14c and the precipitated foreign matter are forcibly discharged to forcibly discharge the rainwater contained in the inner space 14.
