The present invention relates to a vertical grease filter of an exhaust hood, and in particular, is configured to improve the function of collecting and dripping the fine oil during the process of exhaust gas containing the fine oil through the hood.

An exhaust hood is installed in the kitchen to exhaust the gas generated in the kitchen to keep the indoor space comfortable. While cooking in the kitchen, the heated fine oil is scattered in the air in the form of steam. When the fine oil scattered in such a vapor state is attached to a wall or a cooking utensil, it may not be easily removed, resulting in a dirty kitchen.

In order to overcome this problem, an exhaust hood is generally installed on a heating table of a kitchen.

1 is a schematic view showing a general exhaust hood, Figure 2 is a cross-sectional view showing a grease filter of the exhaust hood according to the prior art.

As illustrated in FIG. 1, the exhaust hood 1 is installed on the upper portion of the heating table 3, and sucks gas that rises in a heated state from the heating table 3 to exhaust the gas outdoors. On the other hand, the exhaust hood 1 is equipped with a grease filter 10 to collect the fine oil contained in the exhaust gas exhausted through the exhaust hood 1 to prevent the air pollution by the exhaust gas exhausted to the outside. .

As shown in FIG. 2, the grease filter 10 includes a rectangular frame 15, a plurality of first registers 11 opened upwardly and parallel to each other inside the frame 15; And a plurality of second registers 12 which are opened downward, and both ends of the widths of the second registers 12 are positioned inside the openings of the two first registers 11 arranged in parallel. 15) is fixed.

Therefore, the rising exhaust gas rises upwards between the first registers 11 and contacts the inner surface of the second register 12, and then inside the first register 11 along the inner surface of the second register 12. After flowing in, it exits again between the second register 12 along the inner surface of the first register 11 and is exhausted.

During the flow of the exhaust gas, the fine oil contained in the exhaust gas primarily moves along the outer surface of the first resistor 11, and then strikes the inner surface of the second resistor 12, and then the second resistor. After moving along the inner surface of (12), it hits the inner surface of the first register (11). And it flows along the outer surface of the 2nd resistor 12, and is exhausted. As described above, the fine oil is fixed to the registers 121 and 122 while hitting or moving along the inner and outer surfaces of the resistors 121 and 122 with the exhaust gas many times. As the number of times that the fine oil contacts the registers 121 and 122 increases, the amount of fine oil that is collected and droplets in the registers 121 and 122 increases, thereby improving the cleanliness of the exhaust gas exhausted.

However, it is extremely difficult to further improve the cleanliness of the exhaust gas using such a conventional grease filter.

Therefore, in the related art, a thin porous filter is disposed on the front surface of the grease filter 10 so that the exhaust gas passes primarily through the porous filter 17. However, such a structure also has a thin thickness of the porous filter 17, thereby making it easy to fine oil. There is a drawback to passing.

In addition, the porous filter 17 is located in front of the grease filter 10, there is a disadvantage that the appearance is not beautiful.

The present invention is designed to solve the problems of the prior art as described above, by reducing the temperature of the exhaust gas by increasing the time that the exhaust gas passes through the porous filter, thereby reducing the droplet of the fine oil contained in the exhaust gas It is an object of the present invention to provide a vertical grease filter of an exhaust hood that can be improved.

As shown in FIGS. 3 and 4, the vertical grease filter 100 includes a stator 110 positioned to face each other, and a plurality of first resistors fixed at both ends and open to the stator 110. 121 and a plurality of second registers 122 which are positioned inwards of the two first registers 121 that are both ends fixed to the other fixing base 110 and both ends of the width are parallel to each other, and which are opened forward; And a plurality of porous filters 130 positioned between the inner surfaces of the first and second registers 121 and 122 facing each other, and a frame 150 surrounding the stator 110 arranged in two rows. do.

Hereinafter, a vertical grease filter configured as described above will be described in detail.

Two pairs of fixtures 110 are positioned up and down, the width of both ends are bent in the outward direction, the first resistor 121 is aligned between the two oppositely positioned fixing poles 110, the other two fixtures ( With the second register 122 aligned with the 110, both ends of the first register 121 and the second register 122 are fixed to the holder 110.

The first register 121 and the second register 122 are a channel structure having a 'c' shape in which the middle of the width is bent in parallel twice, and is formed by pressing a flat plate. Both ends of the first and second registers 121 and 122 configured as described above are fixed to the other fixing base 110 as shown in FIG. 5, and the holes 113 are formed in the fixing base 110 to be assembled. The protruding pieces 125 formed at the end portions of the registers 121 and 122 are formed by assembling the fixing base 110 after matching with the holes 113.

As such, when the fixing stand 110 and the registers 121 and 122 are assembled, there is an advantage in that the fixing stand 110 and the registers 121 and 122 can be separated and cleaned later.

Meanwhile, the plurality of first registers 121 are spaced apart from each other in parallel in an open rearward manner, and the plurality of second registers 122 are positioned between the first registers 121 and the second registers 122. The width of both ends of the width is positioned to be opened to the front so as to be located inside the first register 121, which is located to open to the rear.

The first register 121 and the second register 122 aligned as described above are spaced apart at predetermined intervals, and thus, between the inner surface of the first register 121 facing each other and the inner surface of the second register 122. The porous filter 130 is fitted to each other.

At this time, the length of the porous filter 130 is the same as the length of each register (121, 122), the width is smaller than the distance between the inner bending point of the first register 121 and the inner bending point of the second register (122). , The thickness is equal to the distance between the first register 121 and the second register 122. In addition, adjacent porous filters 130 are in contact with each other, and the contacting portions are in contact with a portion of the adjacent porous filters 130 at inner bending points 127 of the registers 121 and 122.

5 and 6, the first resistor 121 fixed to the holder 110 and the second resistor 122 fixed to the other holder 110 are in the form of an assembly 111 arranged in two rows. In the assembled state, the assembly 111 is fixed to the frame 150. And the fixing stand 110 arranged in two rows is fixed by fastening the bolt 155 to the portion bent outward.

On the other hand, the frame 150 is a rectangular closed structure that can wrap the assembly 111, each side of the frame 150 is bent inward so that the assembly 111 is fixed to the inside. In addition, an oil outlet (153 of FIG. 6) is formed on the bottom surface of the rectangular frame 150 so that the oil dropleted in the first and second registers 121 and 122 flows out.

Hereinafter, a process in which the exhaust gas moves through the vertical grease filter 100 will be described with reference to FIG. 4.

The exhaust gas introduced from the front proceeds backward along the outer surface of the first resistor 121, passes through the exposed porous filter 130 after moving to the inner bending point of the second resistor 122. At this time, some of the exhaust gas is changed in direction and flows into the first resistor 121 along the porous filter 130, and some of the exhaust gas flows into the inner space of the second resistor 122. Here, the exhaust gas is temporarily stagnated as the flow direction is changed while hitting the inner surface of the second resistor 122, and the fine oil contained in the exhaust gas in the stagnant state is formed on the inner surface of the second resistor 122. It is red. The primary dropletized oil 141 flows down along the inner surface of the second register 122.

On the other hand, when the exhaust gas passes through the porous filter 130, since the exhaust gas passes in the width direction of the porous filter 130, it is much longer than the distance passing in the thickness direction of the porous filter 130 as in the prior art. As described above, the longer the exhaust gas passes through the porous filter 130, the lower the temperature during the passage, and the second droplet is rapidly increased. Here, in order to efficiently make the secondary droplets, it is preferable that the porous filter 130 is made of a metal material. Since the porous filter 130 is made of a metal material having high thermal conductivity, the exhaust gas can be easily cooled, and it is excellent in heat resistance, easy to clean, and droplets of oil can easily flow down. have.

Therefore, the secondary dropletized oil 142 and the primary dropletized oil 141 pass through the porous filter 130 and are collected by flowing into the first resistor 121.

Meanwhile, the exhaust gas passing through the porous filter 130 is exhausted backwards through the second resistors 122. As the exhaust gas passes through the assembly 111 as described above, the fine oil contained in the exhaust gas is dropletized.

On the other hand, the oil droplets on the inner surface of the first register 121 and the second register 122 and the porous filter 130 flows down, passes through the hole 113 of the fixing unit 110, the frame 150 ) Flows inward. And it is discharged through the outlet 153 formed in the frame 150, the hose is connected to the outlet 153.

As described above in detail, the vertical grease filter of the exhaust hood of the present invention is not only dropletized as the exhaust gas passes or collides with the first resistor and the second resistor, but also has a long distance through the porous film. Improve oil droplet effect. In addition, as the flow distance of the exhaust gas is increased, the temperature of the exhaust gas is lowered during the flow, thereby further activating dropletization.

Therefore, there is an advantage that the air pollution can be reduced by reducing the amount of fine oil contained in the exhaust gas exhausted to the atmosphere.

In addition, the vertical grease filter of the exhaust hood of the present invention has the advantage that the porous filter is located inside the grease filter, the appearance is beautiful.

The technical idea of the vertical grease filter of the exhaust hood of the present invention has been described together with the accompanying drawings, but this is only illustrative of the best embodiment of the present invention and is not intended to limit the present invention.
