And a flow path formed by various ducts (not shown).

The ventilation device 10 is provided so as to protrude upward from the upper surface of the main body 50 and biased toward the upper surface edge of the main body 50.

The ventilator 10 absorbs polluted air, smoke or odor generated when the heating device 610 cooks food.

The ventilator 10 is kept protruded upward from the main body 50 during operation but is inserted into the main body 50 as shown in Fig. In other words, it is inserted up to a height similar to the height of the cooking chamber 60 in non-operation. Thus, the ventilation device 10 is inserted into the main body 50 and is clean and has high space utilization.

Fig. 3 is a view showing the internal structure of the main body of the ventilation system of Fig. 1, and Fig. 4 is a view showing the ventilation system of Fig.

As shown in FIGS. 3 and 4, the housing 100 forms the contour of the ventilator 10. Furthermore, the housing 100 accommodates other configurations of the ventilator 10. [

In the housing 100, a suction port case 150 for forming a suction port 120 (see FIG. 6) through which contaminated air or the like is sucked is disposed. A suction guide 110, which covers the suction port 120 and guides the sucked air, is mounted on the front surface of the suction port case 150.

The suction guide 110 includes a guide body 111 and a suction hole 112 formed through the guide body 111 and through which contaminated air is sucked. The contaminated air flows into the suction port 120 (see FIG. 6) through the suction hole 112.

The outlet case 250 is disposed on both sides of the inlet case 150. In the outlet case 250, an outlet 230 is formed. The vortex generating unit 200 is mounted on the front surface of the discharge port 230.

The vortex generating unit 200 includes a body 210 and a discharge hole 220 formed through the body. A vortex is formed outside the front surface of the ventilator 10 as air is discharged through the vent hole 220. This will be described in detail in Fig.

A fan cover 350 is mounted on the lower portion of the inlet port case 150. The fan cover 350 forms a fan receiving portion 360 therein. A suction fan 300 is disposed inside the fan housing 360.

The suction fan 300 is mounted so as to communicate with the suction port 120 (see Fig. 6). Accordingly, when the suction fan 300 generates a suction force, the contaminated air is sucked into the suction port 120.

In this embodiment, the suction fan 300 means a sirocco pan. The sirocco fan is one of the centrifugal blowers, and a plurality of short and wide vanes are formed protruding outward in the radial direction. The Sirocco fan is a fan that is mainly used as a ventilation fan because of its low noise.

The contaminated air is discharged into the discharge passage 410 by the suction fan 300 inside the fan receiving portion 360.

5 is a cross-sectional view taken along the line A-A in Fig.

As shown in FIG. 5, the housing 100 is disposed to cover the suction port case 150 and the discharge port case 250. The discharge hole 220 of the vortex generation unit 200 mounted on the front surface of the discharge port case 250 is formed to be inclined from the discharge port 230 toward the outer side of the housing 100 toward the outside of the housing 100. That is, the air discharged through the discharge port 230 is formed so as to be directed more outward than the edge of the upper surface of the main body 50.

The air discharged by the discharge hole 220 is not discharged in a direction perpendicular to the front surface of the ventilator 10 but is discharged to the outside of the side surface of the ventilator 10 at a predetermined angle with the front surface of the ventilator 10 .

Fig. 6 is a cross-sectional view showing the flow of air sucked into the ventilation system of Fig. 1;

6, contaminated air containing contaminants is sucked into the suction port 120 through the suction hole 112 of the suction guide 110 by the suction force of the suction fan 300. As shown in FIG.

The contaminated air sucked into the suction port (120) flows into the suction path (130) connected to the lower side of the suction port (120).

A first filter 610 is installed in the suction passage 130. The first filter 610 means a grease filter. The grease filter is a filter that collects the oil contained in the contaminated air to make it droplet. It removes oil components from the contaminated air to purify the air while preventing deformation of the duct which forms the air flow path and prevents the fire caused by the high temperature oil.

The air introduced into the suction passage 130 passes through the first filter 610 and the oil component is removed.

The upper side of the suction passage 130 communicates with the suction port 120 and the lower side communicates with the fan receiving portion 360. Therefore, the contaminated air that has passed through the grease filter of the suction passage 130 flows into the fan storage portion 360.

The contaminated air is introduced into the suction fan 300 from the fan storage part 360 and discharged to the discharge flow path 410 connected to the lower side of the fan storage part 360 by the wings of the suction fan 300.

A second filter 620 is installed inside the discharge passage 410. The second filter 620 is a filter for removing volatile organic compounds (VOCs).

The volatile organic compound means a hydrocarbon compound which is volatilized in the air to generate odor or ozone. In particular, volatile organic compounds themselves are directly harmful to the environment and human body, and further participate in photochemical reactions in the atmosphere to generate secondary pollutants such as photochemical oxides.

Volatile organic compounds are one of the carcinogens and must be removed essentially to remove contaminated air into the room. Accordingly, the volatile organic compound is removed from the air contaminated by the second filter 620 and purified by clear air.

The air filtered by the pollutant is in a condition suitable for being discharged to the room.

Therefore, a part of the air passing through the second filter 620 in the discharge passage 410 is discharged to the outside of the case through the outlet 420. The exterior of the case is the room where the ventilation system 1a is located.

The polluted air is purified inside the ventilation system 1a and discharged directly to the room, so there is no need to connect the duct to the outside.

The air that has not been discharged through the outlet 420 of the air filtered by the second filter 620 flows into the branch passage 430.

FIG. 7 is a cross-sectional view showing the flow of air discharged by the ventilation system of FIG. 1; FIG.

7, the branch passage 430 is disposed between the discharge passage 410 and the ascending passage 440 to communicate the discharge passage 410 and the ascending passage 440 with each other. Therefore, the air that has flowed into the branch flow path 430 flows into the rising flow path 440 through the branch flow path 430.

The lower part of the ascending channel 440 is connected to the branch channel 430 and the upper part is connected to the exhaust port 230. Thus, the air rises along the upflow channel 440 and flows to the outlet 230.

The air moved to the discharge port 230 is discharged to the front surface of the ventilator 10 through the discharge hole 220 of the vortex generating unit 200 to generate a vortex.

The generation of vortex will be described in detail in Fig.

By using such a flow path structure, a vortex can be generated without using a separate driving device. However, it is also possible to include in the spirit of the present invention, a vortex is generated by discharging air to the discharge hole 220 of the vortex generating unit 200 by using a separate driving device.

Fig. 8 is a diagram showing the external air flow by the vortex formed by the ventilation system of Fig. 1;

8, the air is discharged to the outside of the left and right edges of the upper surface of the main body 50 by the discharge hole 220 of the vortex generating unit 200. As shown in Fig. At the same time, the air sucked by the suction guide 110 is sucked by the suction fan 300 (see Fig. 3). According to this structure, the air density is lowered in the front portion of the suction guide 110.

The air discharged from the discharge hole 220 of the vortex generation unit 200 toward the outer side of the housing 100 rotates toward the center of the upper surface of the main body 50. When the air is rotated in this way, a vortex is formed. Further, the suction force of the suction fan 300 causes the air to flow toward the center of the upper surface of the main body 50, thereby forming a vortex.

When the vortex is formed, the contaminated air generated in the portion farther from the suction guide 110 can be sucked without increasing the capacity of the suction fan 300. Moreover, the contaminated air generated in the portion near the suction guide 110 has a high suction efficiency.

In addition, this vortex can form an air curtain to reduce the spreading of the contaminated air generated in the cooking chamber 60 to the entire room.

[

The housing 100 forms the appearance of the ventilator 10 and accommodates other configurations of the ventilator.

A suction port 110 for forming a suction port 120 is provided in the housing 100 and a suction guide 110 for covering the suction port is mounted on the front surface of the suction port case 150.

The suction guide 110 includes a guide body 111 and a suction hole 112 formed through the guide body 111 and through which contaminated air is sucked.

The outlet case 250 is disposed on both sides of the inlet case 150. A first outlet (230) is formed in the outlet case (250). The vortex generating unit 200 is mounted on the front surface of the first outlet 230. The vortex generation unit 200 includes a body 210 and a first discharge hole 220 formed through the body.

The shape of the first discharge hole 220 is replaced with the description of the discharge hole 220 shown in FIG.

The suction-enhancing unit 700 is mounted on the left and right sides of the cooking chamber 60 on the upper surface of the main body 50. The suction reinforcement unit 700 includes a plate 710 and a second discharge hole 720 formed through the plate 710.

11, the second exhaust hole 720 is formed so as to be inclined toward the rear, that is, toward the suction guide 110, from the inside to the outside of the main body 50. As shown in FIG. Therefore, the air discharged through the second discharge hole 720 is directed to the suction guide 110, not in a direction perpendicular to the upper surface of the main body 50.

12 is a sectional view showing the flow of air sucked into the ventilation system in Fig.

12, the contaminated air including the contaminants is sucked into the suction port 120 through the suction hole 112 of the suction guide 110 by the suction force of the suction fan 300. As shown in FIG.

The contaminated air sucked into the suction port (120) flows into the suction path (130) connected to the lower side of the suction port (120).

A first filter 610 is installed in the suction passage 130. The first filter 610 removes oil contained in the contaminated air as a grease filter.

The upper side of the suction passage 130 communicates with the suction port 120 and the lower side communicates with the fan receiving portion 360. Therefore, the contaminated air that has passed through the grease filter of the suction passage 130 flows into the fan storage portion 360.

The contaminated air is introduced into the suction fan 300 from the fan storage part 360 and discharged to the discharge flow path 410 connected to the lower side of the fan storage part 360 by the wings of the suction fan 300.

A second filter 620 is installed inside the discharge passage 410. The volatile organic compounds in the air contaminated by the second filter 620 are removed.

The air filtered by the pollutant is in a state suitable for being discharged to the room, and a part of the air is discharged to the outside of the case, that is, the room through the outlet 420.

The air that has not been discharged through the outlet 420 flows into the branch passage 430.

Fig. 13 is a cross-sectional view showing the flow of air discharged by the ventilation system in Fig. 9; Fig.

As shown in FIG. 13, the air introduced into the branch passage 430 flows into the upward passage 440 through the branch passage 430.

The lower portion of the ascending channel 440 is connected to the branch channel 430 and the upper portion of the ascending channel 440 is branched to the first outlet 230 and the second outlet 730. Therefore, a part of the air that has entered the upflow channel 440 flows into the first outlet 230 and the remaining air flows into the second outlet 730.

The air introduced into the first outlet 230 is discharged to the front surface of the ventilator 10 through the first vent hole 220 of the vortex generator unit 200 to generate a vortex.

The air introduced into the second outlet 730 is discharged toward the suction guide 110 through the second discharge hole 720 of the suction reinforcement unit 700.

As described above, a vortex can be generated without using a separate driving device. Further, the suction of contaminated air can be made stronger without a driving device. However, it is also possible to incorporate the driving device into the vortex generation unit 200 or the suction reinforcement unit 700 to discharge air.

14, the air discharged by the first discharge hole 220 of the vortex generation unit 200 is directed toward the left side and the right side outer side of the main body 50, not toward the cooking cavity 60. [ At the same time, the air sucked by the suction guide 110 is sucked by the suction fan 300 (see Fig. 12). Therefore, the air density is lowered in the front portion of the suction guide 110, and the air discharged by the first discharge hole 220 is turned toward the center of the cooking chamber 60. This creates a vortex as the air swirls.

The air discharged from the second exhaust hole 720 of the suction enhancing unit 700 further swirls and swirls air to flow faster. At the same time, the flow of air toward the suction guide 110 is enhanced to increase the amount of air sucked into the suction port 120.

That is, the suction efficiency can be further improved without increasing the capacity of the suction fan 300.

19 is a view showing a swirler fan in Fig. 19. Fig.

19, the swaller fan 70 is composed of a rotating plate 710 rotating about a rotating shaft 730 and a plurality of blades 720 arranged in a circumferential direction on the rotating plate 710 . The wings are formed protruding in a direction perpendicular to the plane of the rotary plate 710.

The driving force of the driving unit 750 is transmitted to the rotating plate 710 through the shaft 760.

When the swirler fan 70 having the same structure as the drawing is rotated, air is radially outwardly discharged from the rotary plate 710. Thus, air is discharged to both sides of the inflow guide 110. Further, the discharged air is inclined outward from both sides of the main body 50 and discharged.

FIG. 20 is a view showing another embodiment of the ventilator of FIG. 19;

As shown in Fig. 20, two swirler fans 71 and 72 are mounted on the ventilator 10.

Due to the shape of the fan, the amount of open emission varies depending on the direction in which the air is discharged. Therefore, when there is only one swather fan, more air is discharged only in the direction of one of the left and right sides of the inlet guide 110, and thus a larger vortex is generated. That is, the intake amount of contaminated air may be different on the left side and the right side.

In this embodiment, two sweller fans 71 and 72 are installed to balance the amount of air discharged to the left and right sides of the inlet guide 110.

The swirling directions of the swaller fans 71 and 72 may be reversed or the swirling directions of the swather fans 71 and 72 may be reversed to balance the air discharge amounts on both sides.

Fig. 21 is a diagram showing the external air flow by the vortex formed by the ventilation system in Fig. 18;

As shown in Fig. 21, the swirler fan 70 discharges air toward the left side and the right side outward of the main body 50. As shown in Fig. At the same time, the air sucked by the suction guide 110 is sucked by a suction fan (not shown). Accordingly, the air density is lowered in the front portion of the suction guide 110, and the air discharged by the swather fan 70 is turned toward the center of the cooking chamber 60. This creates a vortex as the air swirls.
