Description

Wet and Dry Air Cleaner

The present invention relates to an air cleaner for cleanly purifying fresh air supplied to an engine, and in particular, by forming the air cleaner in a dry and wet dual structure, improving the clean efficiency of the fresh air, improving the life and efficiency of the engine, and replacing the filter paper. It relates to a wet and dry air cleaner with an extended period.

In general, an intake apparatus used for an engine includes an air cleaner 10 that sucks external air to filter impurities as shown in FIG. 1, and an air flow meter that checks the amount of air that has passed through the air cleaner 10 ( 2), a throttle body 3 whose opening degree is controlled to pass only as much air as the engine requires, and a surge tank 4 for temporarily storing the air passing through the throttle valve 3 to reduce intake pulsation. And an intake manifold (not shown) through which the surge tank 4 and each combustion chamber of the engine are connected to allow the air in the surge tank 4 to pass, thereby purifying external air from the air cleaner 10. Temporarily stored in the surge tank 4 through the air flow meter 2 and the throttle body 3 and then supplied to each combustion chamber of the engine through an intake manifold.

In particular, the air cleaner 10 is generally installed in the air horn portion of the vaporizer to remove most foreign substances contained in the air. In addition, the air cleaner 10 also serves to reduce intake sound generated in the intake system.

There are two types of air cleaner 10 currently used, dry using filter paper or synthetic fibers and wet using oil, and FIG. 2 shows a dry air cleaner.

Here, in the conventional dry air cleaner, as shown in FIG. 2, the filter paper 15 is installed inside the case 12 in which the air inlet 12a and the air outlet 12b are formed, thereby providing the inlet 12a. Through this, the impurities and foreign substances in the air sucked into the case 12 are purified and supplied to the engine.

The dry air cleaner 10 radially inserts the filter paper 15 into the casing 12 so that air is passed through the filter paper 15 from the outside and the foreign matter is removed in the center to collect the outlet 12b. Through the carburetor.

In recent years, porous synthetic fibers are used instead of the filter paper 15 to improve the filtration accuracy and to reduce the clogging of the filter material.

On the other hand, the wet air cleaner (not shown) is made of a double steel case, and a predetermined amount of engine oil is embedded at the bottom so that the metal element is contained in the case. Air is sucked through the gap between the case and the cap, weighty debris is ground into the oil and light debris is removed from the oiled metal element.

However, since the conventional dry air cleaner constructed and operated as described above purifies the air using the filter paper, there is a limit in purifying and supplying the air supplied to the engine more cleanly, especially when the filter paper is used for a long time. There is a problem of being blocked or torn.

In addition, the wet air cleaner has a problem that the filtration efficiency increases as the amount of air sucked into the engine increases, but the filtration efficiency decreases when the amount of air intake decreases in a state in which the rotation speed of the engine is slow.

The present invention has been made to solve the above problems, by combining the dry using the filter paper and the wet using oil to form a double structure to improve the clean efficiency of the air cleaner to increase the life and efficiency of the engine and filter To provide a wet and dry air cleaner that extends the life of the paper.

The wet and dry air cleaner of the present invention for achieving the above object is an air cleaner comprising a case in which an air inlet and an outlet are formed, and a filter paper installed in the case to purify the air sucked into the engine. It is characterized in that the wet purifying means is installed to remove the foreign matter by using oil so that the air introduced between the case and the filter paper is first purified.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

As shown in FIG. 2, the wet and dry air cleaner according to the present invention is provided with a case 52 in which an air inlet 52a and an outlet 52b are formed, and the air is installed in the case 52 to purify the air sucked into the engine. A wet purifying means 60 is installed to remove foreign substances by using oil so that air introduced between the filter paper 55 and the case 52 and the filter paper 55 is first purified.

In addition, the wet purifying means 60 is installed between the case 52 and the filter paper 55 so that the air passages are formed in the lower and upper sides of the outer partition 62 and the inner partition 64 so that air passes in a zigzag form. And an oil cup 66 installed on the vent between the case 52 and the inner partition 54 to store oil so that the air sucked into the case 52 is first purified, and the outer partition 62. ) And a metal element (68) containing oil so as to secondaryly purify the air passing through the upper surface of the oil cup (66).

Referring to the operation of the wet-dry air cleaner of the present invention configured as described above are as follows.

When the engine is operated, the air is purged and sucked through the wet and dry air cleaner 50 according to the present invention by the negative pressure of the combustion chamber.

Here, the air sucked into the engine is introduced between the case 52 and the outer partition wall 62 through the inlet port 52a of the case 52, and the air introduced therein strikes the oil level stored in the oil cup 66. Most of the dust is then attached to the oil and removed first, and then secondly purged in the metal element 68 between the outer partition 62 and the inner partition 64.

That is, the metal element 68 is always in the wet state when the air hits the oil of the oil cup 66, the oil droplets are jumping, and the first purified air hit the oil from the metal element 68 The secondary purification is led to the filter paper 55.

The air drawn around the filter paper 55 is cleanly and tertiarily purged while passing through the filter paper 55 to be supplied to the engine through the outlet 52b of the case 52.

Since the dry and wet air cleaners according to the present invention are constructed and functioned as described above, the dry and wet air cleaners are composed in a combination, and thus, the filtration efficiency of the air is increased to improve the output efficiency of the engine and to extend the service life.
