In order to exhaust the polluted air, an exhaust part 7 composed of an exhaust fan, an exhaust chamber 5 and an exhaust port 6 is formed.

In addition, the discharge unit 20 forms a chamber 25 through which the external air is sucked and a first discharge port 21 at one side of the chamber 25 to discharge the external air in a horizontal direction, and the external air at a predetermined inclination angle. A second discharge port 22 to discharge the air, a third discharge hole 23 to discharge the external air in a vertical direction, and guide air to induce contaminated air toward the exhaust port 6. It consists of a fourth discharge port 24 for discharging the.

It is preferable to form the inclination angle of the second discharge port 22 at 11 to 17 degrees.

In addition, the contaminated air intake unit 30 is formed below the discharge unit 20, and the plurality of louvers 31 and the lower side of the louver 31 so that foreign substances such as moisture or oil may move. The flow path 32 is formed.

And the cover portion 40 is formed on the front of the contaminated air intake portion 30, and forms a handle 42 to be easily separated when separated from the perforated portion 41 that can suck the air on the front and The inner side is provided with a catching portion 44 to be mounted on the streamlined oil collecting portion 43 and the contaminated air suction portion 30.

It consists of the 2nd auxiliary louver 52 and the 2nd flow path 53. As shown in FIG.

In addition, an exhaust fan 60 capable of sucking air in a horizontal direction formed in the exhaust chamber 5 and an oil collecting box 70 connected to the first and second flow paths 32 and 53 are formed. have.

Looking at the preferred embodiment of the range hood of the present invention having the configuration as described above are as follows.

In order to prevent the diffusion of polluted air generated during food cooking and to discharge the polluted air generated by using the range hood 100, the power is applied by turning on the switch 9 formed on the front of the range hood 100.

Then, the air supply fan 1 of the air supply unit 4 formed above the range hood 100 and the air exhaust fan 60 formed in the exhaust chamber 5 operate.

First, referring to the process of forming the induction air so that the air curtain and the polluted air can be smoothly exhausted by the air supply fan 1 of the air supply unit 4, the air supply fan 1 of the air supply unit 4 as described above. When this operation is performed, the air inlet 3 formed on the upper side of the range hood 100 sucks outside air, and the sucked external air passes through the air supply chamber 2 to the contaminated air intake unit 30. External air flows into the formed chamber 25.

Then, the outside air introduced into the chamber 25 is discharged by air curtains and polluted air by the first, second, third and fourth discharge ports 21, 22, 23, 24 formed in the discharge part 20. Induced air is discharged so that it can be easily introduced into.

In detail, the first discharge port 21 formed to discharge the air in the horizontal direction discharges the air having a high pressure in accordance with the direction of the air flowing in the air supply chamber 2, wherein the first discharge port 21 is discharged. The external air discharged from the discharge port 21 is discharged in the horizontal direction, and as the discharge distance increases as shown in FIG. 5 due to friction with air, the air is dropped downward to form an air curtain.

In addition, the second discharge port 22 formed on the inclined surface having a predetermined inclination angle is to discharge the external air in a direction perpendicular to the inclination angle, by the inclination angle formed by the direction of the air flowing in the air supply chamber (2) and the inclined surface Air having a lower pressure than the first discharge port 21 is discharged to form an air curtain.

The third discharge port 23 formed to discharge air in the vertical direction is formed at a portion perpendicular to the direction of the air flowing in the air supply chamber 2, so that the pressure is weaker than that of the second discharge port 22. The air curtain is formed by discharging the external air in the vertical direction.

As described above, the air curtain formed by the first discharge port 21, the second discharge port 22, and the third discharge port 23 is applied to the air curtain by the combustion action and convection to generate heat in the range 10. A part of the formed external air moves in the direction of the contaminated air intake unit 30.

In addition, the fourth discharge port 24 is formed to discharge the external air in the reverse direction of the external air flowing in the air supply chamber 2, so that the pressure lower than the third discharge port 23 of the discharge unit 20 It is discharged to, and operates in a direction that can smoothly move the contaminated air generated when cooking food using the range 10 toward the exhaust port (6).

Hereinafter, the operation relationship of the exhaust unit will be described.

At the same time as the operation of the air supply unit 4, the exhaust fan 60 formed in the exhaust chamber 5 is operated.

In general, the polluted air generated when cooking food using the range 10 generates air containing a large amount of foreign matter such as moisture or oil and polluted air containing less foreign matter.

The polluted air containing a large amount of the above-mentioned foreign matters is heavy, so that the height that can rise in the upward direction during vaporization rises lower than that of the polluted air containing less foreign matters.

As a result of this phenomenon, the polluted air containing less foreign matter is raised to a height enough to be sucked by the exhaust fan 60, and the raised polluted air is sucked into the polluted air formed on the front surface of the exhaust fan 60. The contaminated air moves in the direction of the part 30 to pass through the perforated part 41 of the cover part 40 formed on the front surface of the contaminated air suction part 30.

Then, the contaminated air passing through the perforation part 41 of the cover part 40 at a speed lower than the air speed at the time of being sucked by the exhaust fan 60 in the course of passing the perforation part 41 having a small cross-sectional area. Again, it is sucked into the contaminated air suction unit 30.

The polluted air, which has fallen in speed as described above, is moved back to the exhaust chamber 5 by the louver 31 formed in the polluted air intake unit 30 while passing through the contaminated air intake unit 30. 31 has a narrow cross-sectional area, so that only part of the contaminated air that can pass through the louver 31 can pass, and contaminated air that cannot pass through the louver 31 does not have the louver 31 formed thereon. Water vapor is evaporated after a certain time in the state attached to the, foreign matter remaining after the evaporation flows down from the portion where the louver (31) is not formed is collected in the oil collecting portion 43 formed on the lower side of the cover portion 40 It is done.

At this time, only a very small amount of oil or water collected in the oil collecting unit 43 in the process of exhausting the contaminated air containing less foreign matter is collected.

In addition, since the shape of the louver 31 formed in the contaminated air intake unit 30 is such that air can be moved from the upper side to the lower side, the air passing through the louver 31 is moved to the exhaust chamber 5. In the process, it is moved at a high speed in the downward direction of the exhaust chamber (5).

Of the contaminated air passing through the louver 31 in the above process, the contaminated air that is not moved to the exhaust chamber 5 and stuck to the louver 31 is stuck to the louver 31, and after a predetermined time, the vapor is evaporated. After the evaporation, the foreign matter remaining in the louver 31 flows into the oil collecting box 70 formed at the lower side through the first flow passage 32 formed in the contaminated air intake unit 30, and the exhaust air is discharged. The polluted air containing foreign substances among the polluted air passing through the chamber 5 cannot be exhausted to the exhaust fan 60 at a speed that is rapidly moved downward of the exhaust chamber 5, and falls to the lower side of the exhaust chamber 5. The oil is collected in the collecting box (70).

In addition, the polluted air containing a large amount of foreign matter is down to a height that is heavy enough to be absorbed by the exhaust fan 60, the down is not contaminated, the contaminated air downward as described above is an auxiliary pollution formed on the lower side It is sucked by the first auxiliary louver 51 and the second auxiliary louver 52 formed in the air suction unit 50. At this time, most of the polluted air contains a large amount of foreign substances, and thus most of the polluted air In the process of passing through the louver 51 and the second auxiliary louver 52, the first and second auxiliary louvers 51 and 52 are stuck to each other. After a certain time in this state, the water vapor is evaporated and then evaporated. The remaining foreign matter flows down from the first and second auxiliary louvers 51 and 52 and the oil collecting box formed at the lower side through the first flow passage 32 and the second flow passage 53 formed in the contaminated air intake unit 30. Foreign matter is collected in the 70, and has passed through the exhaust chamber (5). Contaminated air including foreign matter in the air cannot be exhausted to the exhaust fan 60 due to the speed of moving rapidly downward in the exhaust chamber 5 as described above, and drops to the lower side of the exhaust chamber 5 to collect oil. It is collected in the box (70).

In addition, the cover part 40 can be easily attached and detached by the catching part 44 and the handle 42 formed to be easily attached and detached, and the oil collecting box 70 can be easily attached and detached to use the range hood 100. After the foreign matter collected cover portion 40 and the oil collection box (70) can be easily separated and washed.

In general, the air curtain is formed to prevent the contaminated air from flying to the kitchen, and the exhaust fan (60) to stagnant air in the area that is not affected by the exhaust fan (60) formed in the range hood (100). By discharging the induction air to be guided in the direction of), the exhaust fan 60 can be discharged to the outside by the exhaust fan to the outside of the contaminated air formed in the area not affected.

As described above, the air curtain formed at the first, second, and third discharge ports 21, 22, 23 by the exhaust fan 60, which sucks the contaminated air in the horizontal direction, has the exhaust fan in addition to the above-described convection phenomenon. 60 is also moved to the contaminated air intake section 30, that is, to the area where contaminated air is generated, and is moved to the exhaust chamber 5 through the contaminated air intake section 30 together with the contaminated air. It is possible to increase the discharge rate by discharging a large amount of polluted air to the outside, and the foreign matter contained in the polluted air is each louver 31 formed in the polluted air inlet 30 and the auxiliary polluted air inlet 50. It is eliminated by (51) (52), and the objective of this invention can be achieved.

As described above, the range hood of the present invention blocks the diffusion of polluted air scattered into the kitchen by the first, second, and third discharge ports of the discharge part in triple, thereby preventing the spread of the polluted air into the kitchen in a wide range. In particular, the direction of the air curtain formed from the second and third discharge ports by the exhaust fan formed to suck air in the horizontal direction is bent in the direction of the contaminated air intake, thereby forming a streamlined air curtain, Not only can the efficiency be increased, but also the polluted air can be smoothly sucked into the exhaust port by the fourth discharge port, thereby increasing the exhaust efficiency. Also, the polluted air sucked by the exhaust fan can be As foreign substances such as moisture and oil contained in the contaminated air pass through the cover part and the auxiliary contaminated air intake part, By being collected in the oil collecting unit and the oil collecting box, it is a useful invention that can reduce the failure of the discharge fan by water or oil.
