However, in this conventional upward-suction smoke intake device for a roaster, the suction end of the smoke suction pipe is disposed in an upward and downward direction, and is configured to suck smoke through a downward opening of the smoke suction pipe, and is disposed upward and downward on the upper side of the roaster. Contaminants may fall from the suction end toward the roaster or food. As well as, Since the smoke intake pipes arranged vertically on the upper side of the roaster are connected in communication with the exhaust duct provided on the ceiling of the room, it is not easy to separate and combine the smoke intake pipes, making it difficult to remove contaminants from the smoke intake pipes. There is a problem.

Accordingly, a method of discharging smoke to the lower side of the roaster installed on the table, that is, a downward suction roaster, has been developed and used to compensate for the various problems of the smoke suction device of the conventional upward suction roaster.

The upward suction type roaster not only spoils the aesthetics by connecting the exhaust duct to the outside through the indoor ceiling, but also requires replacement due to contamination as the structure of the oil vapor filter placed inside the smoke intake pipe located on the upper side of the roaster is a single mesh structure. Not only is the cycle time short, but it also has the problem of making it difficult to check the contamination status of the oil vapor filter placed inside the smoke intake pipe.

In addition, the smoke intake device of the downward-suction roaster, which was developed to complement the shortcomings of the upward-suction roaster, is designed to suck in the smoke generated from the roaster and discharge the smoke from the bottom of the roaster, that is, to the bottom of the table. It has a simple structure in which the smoke is discharged to an external discharge pipe through a smoke discharge device placed at the bottom of the roaster, and a separate smoke purification device is installed in the smoke intake section to filter out contaminants in the form of oil vapor or particles contained in the smoke. Since it was not equipped, the contamination cycle of the smoke exhaust pipe placed on the lower side of the table was accelerated, and the cumbersome work cycle to remove it was accelerated, making management difficult.

For example, the suction fan receiving portion 341 may be formed to have a length that protrudes from the inner surface of the cover 340 and extends to the bottom of the driving motor 380.

As a result, when the suction fan 350 is driven, the air sucked into the inside of the case 310 (suction fan accommodating part 341) through the inlet 345 is exposed to the inner surface of the suction fan accommodating part 341. It can move downward while rotating along.

At this time, the oil contained in the air rotating along the fan 360 is separated from the air and adheres to the inner wall of the suction fan accommodating part 341, and the inside of the suction fan accommodating part 341 is absorbed by the action of gravity. It can be moved downward along the wall.

Meanwhile, the suction unit 300 is provided with an oil storage container 450 in which oil separated from the air moved through the smoke suction pipe 200 is stored.

Accordingly, when the suction fan 350 is driven, the oil separated from the smoke can be collected and easily removed.

According to this configuration, contamination of the surrounding area by oil contained in smoke when the suction fan 350 is driven can be prevented.

After the holder 550 is coupled to the smoke suction pipe 200, the holder 550 may be rotated relative to the smoke suction pipe 200 so that any one of the plurality of divisions can be indicated by the indicator 235. .

More specifically, for example, when an unused oil vapor filter 500 is first coupled to the smoke intake pipe 200, the holder 550 is located in the first compartment (in this embodiment, for example, the first compartment). (570a) (number 1)) can be relatively rotated to be pointed by the indicator 235 of the smoke intake pipe 200.

FIG. 17 is a cross-sectional view of the intake port area of the oil vapor filter of FIG. 2 in a state of use, and FIG. 18 is a diagram showing the oil vapor filter of FIG. 17 and the holder when rotated relative to the intake port.

Food is placed on the grill 170 of the roaster 160 to be heated, and the food can be heated by the roaster 160.

The suction unit 300 may be driven to suction smoke generated when the roaster 160 is operated.

When the suction unit 300 starts operating, the suction fan 350 is driven, and air above the roaster 160 can be sucked in through the suction pipe portion 220 of the smoke suction pipe 200.

The air sucked through the suction pipe 220, that is, the smoke containing oil vapor, passes through the oil vapor filter 500 and the oil vapor in the air can be collected.

Oil vapor in the air may be primarily collected as the air passes through the external filter 510, and oil vapor in the air that has passed through the external filter 510 may be secondarily collected as it passes through the internal filter 520.

The air that has passed through the oil vapor filter 500 moves along the smoke suction pipe 200 and can be sucked into the interior of the suction unit 300. The air sucked into the case 310 through the intake port 345 is rotated along the fan 360. At this time, oil contained in the air may be separated from the air and move downward along the inner wall of the suction fan receiving portion 341.

The air moved to the lower side of the suction fan accommodating part 341 passes through the lower part of the oil storage container 450 and passes between the suction fan accommodating part 341 and the oil storage container 450 to form a plurality of filter units. You will be guided to (400) respectively.

As it passes through each filter unit 400, air with reduced contaminants such as oil and odor is discharged to the outside of the suction unit 300 through the discharge port 325 of the suction unit 300.

Meanwhile, as the usage time elapses, the oil vapor strainer 500 collects contaminants (P) in the area where air moving through the intake port 225 comes into contact, as shown in FIG. 17.

As a result, the oil vapor collection efficiency of the oil vapor strainer 500 may be reduced.

If the collection efficiency of the oil vapor strainer 500 is expected to decrease after a preset time or number of uses has elapsed, the holder 550 may be rotated relative to the smoke suction pipe 200.

Specifically, when the holder 550 is rotated so that the second compartment 570b (number "2") shown in FIG. 15 is moved to a position corresponding to the indicator 235 of the smoke intake pipe 200, FIG. As shown in Figure 18, the contaminated area of the oil vapor strainer 500 is rotated away from the opening of the vertical pipe portion 210.

When the oil vapor strainer 500 is rotated, a new area of the oil vapor strainer 500 is disposed to correspond to the opening of the vertical pipe portion 210. As a result, the collection efficiency of the oil vapor strainer 500 can be increased.

As described above, if the collection efficiency of the oil vapor filter 500 is expected to decrease due to the collected pollutants (P), the oil vapor filter 500 is not separated from the smoke intake pipe 200, and the holder 550 By rotating with respect to the smoke intake pipe 200, a decrease in the collection efficiency of the oil vapor strainer 500 due to pollutants (P) can be suppressed.

In addition, when checking whether the oil vapor strainer 500 is contaminated after using it for a certain period of time or a certain number of times, use the holder 550 located at the upper end of the vertical pipe portion 210 of the smoke intake pipe 200 to remove the oil vapor strainer 500. When separated from the vertical pipe portion 210, it is possible to easily check the contamination state of the oil vapor strainer 500.

When the oil vapor filter 500 is generally contaminated, or when you want to clean the oil vapor filter 500, hold the holder 550 and pull the holder 550 to separate from the smoke intake pipe 200. The oil vapor strainer 500 is pulled out from the smoke intake pipe 200.

Next, the contaminants (P) attached to the oil vapor strainer 500 can be separated and removed using water, a detergent, a brush, etc.

Meanwhile, when removing oil from the oil storage container 450 inside the suction unit 300, the cover 340 is separated from the case body 320.

At this time, the fan 360 is exposed to the outside. When the fan 360 is held and pulled upward along the axial direction, the fan 360 is separated from the rotation shaft 381.

Next, the oil storage container 450 can be separated from the rotating shaft 381 and taken out from the case body 320, and then the oil inside the oil storage container 450 can be removed.

After the rotating shaft 381 is accommodated inside the penetrating portion 457 of the oil storage container 450, the rotating shaft 381 is accommodated in the rotating shaft receiving portion 363 of the fan 360.

When the rotating shaft 381 is inserted into the rotating shaft receiving portion 363, when the fan 360 is rotated relative to the rotating shaft 381, the protrusion 367 is moved to the protruding receiving portion 383 of the rotating shaft 381. By being inserted into the fan 360 and the rotation shaft 381, the fan 360 and the rotation shaft 381 may be mutually restrained in the circumferential direction (rotation direction).

This difference in appearance is due to the simple operation of separating the oil vapor filter 500 from the vertical pipe part 210 using the holder 550 when the oil vapor filter 500 is contaminated, then changing the direction and reassembling the oil vapor filter (500). 500) provides the advantage of being able to adjust the angle.

Since other configurations and operations are the same or similar to the smoke intake device of the above-described embodiment, detailed descriptions are omitted.

Figure 20 is a cross-sectional view of a smoke intake device for a roaster according to another embodiment of the present invention. As shown in FIG. 20, the smoke suction device for a roaster of this embodiment has an outer diameter of the oil vapor strainer 500 formed to be smaller than the inner diameter of the vertical pipe portion 210 of the smoke suction pipe 200, so that it is perpendicular to the oil vapor strainer 500. A predetermined gap (G) is maintained between the pipe parts 210, and in this embodiment, when the smoke generated in the roaster 160 is inhaled through the suction pipe part 220, the entire surface of the oil vapor strainer 500 is maintained. By allowing it to flow into the vertical pipe portion 210 while passing, contamination of the oil vapor filter 500 is limited to the area in contact with the opening, thereby extending the contamination cycle of the oil vapor filter 500, thereby extending the oil vapor filter 500 ( 500) has the effect of extending the cycle of separate angle adjustment work, replacement, and cleaning work due to contamination.

In this embodiment, other configurations are the same except that the outer diameter of the oil vapor strainer 500 is smaller than the inner diameter of the vertical pipe portion 210 of the smoke intake pipe 200, so detailed description is omitted to avoid duplication.

The inner and outer filters 520 and 510 of the oil vapor strainer 500 applied to various embodiments of the present invention described above may have the same mesh size, or may be configured differently.

For example, the mesh of the external filter 210, which primarily filters harmful substances such as oil vapor contained in the smoke flowing in through the suction pipe 220, is enlarged, and the mesh of the internal filter 220, which secondarily filters, is made external. By making it smaller, that is, more densely, than the mesh of the strainer 210, the efficiency of filtering out harmful substances can be increased.

In addition, in the above embodiment, the oil vapor strainer 500 is shown and explained as being disposed on the vertical pipe portion 210 of the smoke suction pipe 200, but the smoke suction pipe ( It may be configured by placing it at a predetermined portion of the suction pipe portion 220 of 200).

In the above, specific embodiments of the present invention have been shown and described. However, since the present invention can be implemented in various forms without departing from its spirit or essential characteristics, the embodiments described above should not be limited by the content of the detailed description.

In addition, even if the embodiments are not individually listed in the detailed description described above, they should be interpreted broadly within the scope of the technical idea defined in the appended patent claims. In addition, all changes and modifications included within the technical scope of the above claims and their equivalents shall be encompassed by the appended claims.
