A pair of guide plates 25 for guiding the gas discharged from 22 to the discharge port 24 is provided.
[0015]
Here, the exhaust activation unit 20 serves to activate the gas discharged from the kitchen so that the gas is smoothly sucked into the intake port 14 side.
[0016]
The dividing partition 21 serves to divide a part of the gas discharged from the exhaust port 13 toward the exhaust activation part 20 side, and the gas divided by the dividing partition 21 is discharged. It is preferable to make it about 10 to 20% of the total gas to be produced.
[0017]
In addition, the duct 22 serves as a flow path for transferring the gas divided by the dividing partition 21 to the chamber 23 side.
[0018]
The chamber 23 serves as a space in which the divided gas is collected, and is preferably provided in the case 11.
[0019]
The discharge port 24 is an outlet through which the gas collected in the chamber 23 is discharged, and is preferably provided on the front side of the lower portion of the hood 1 because the front side of the hood 1 The gas discharged from the kitchen is activated while the gas generated from the kitchen is blocked from flowing into the room, and the suction input of the intake port 14 by the exhaust fan 12 is performed. It is for raising.
[0020]
In addition, the guide plate 25 is provided inside the chamber 23 to which the end of the duct 22 is attached, and is provided obliquely on the discharge port 24 side so that the gas discharged from the duct 22 is smoothly supplied to the guide plate 25. It serves to be moved to the discharge port 24.
[0021]
Therefore, a part of the exhaust gas sucked by the exhaust fan 12 is divided by the dividing plate 21 and flows into the duct 22 and is collected in the chamber 23 from the duct. 25, and is sent to the discharge port 24 and discharged from the discharge port 24 to the lower front side of the hood 1 to activate the gas generated from the kitchen and easily enter the suction port 14. Try to be inhaled.
[0022]
Therefore, the exhaust activation unit 20 enhances the exhaust power of the exhaust fan 12 with a part of the gas exhausted by the exhaust fan 12, thereby maximizing the exhaust efficiency of the hood 1. is there.
[0023]
As shown in FIG. 2, when the side view of the hood according to the present invention is viewed, the hood 1 includes a known exhaust unit 10 and an exhaust activation unit 20. The exhaust fan 12 is provided inside the case 11, the intake port 14 is provided on the lower side of the exhaust fan 12, and the exhaust port 13 is provided on the upper side of the exhaust fan 12.
[0024]
The exhaust activation unit 20 includes a partition plate 21 that vertically divides the exhaust port 13, and a duct 22 that extends from the partition plate 21 to the outside of the case 11. A chamber 23 in which a guide plate 25 is provided is provided inside the case 11, and a discharge port 24 is provided at the end of the chamber 23 so that the gas divided on the lower surface of the hood 1 is injected. It is provided and configured.
[0025]

[0026]
Accordingly, the discharge port 24 is preferably formed on the front side of the lower surface of the hood 1 because the exhaust gas generated on the lower side of the hood 1 does not flow into the kitchen or the room. The gas ejected from the discharge port 24 serves as an air curtain, and at the same time, activates the exhaust gas to easily flow into the intake port 14.
[0027]
Therefore, as a whole, the present invention includes the exhaust activation unit 20 in the exhaust unit 10, and discharges a part of the gas discharged by the exhaust unit 10 to the inside through the exhaust activation unit 20. By activating the exhaust gas flowing into the intake port 14, the exhaust efficiency of the exhaust unit 10 is maximized, thereby significantly improving the environment in the kitchen and the room.
[0028]
As shown in FIG. 3, when the side sectional view showing the use state of the hood according to the present invention is seen, the arrow shown in FIG. 3 indicates the flow of gas discharged from the gas range 2 of the kitchen. However, the gas discharged from the gas range 2 along the direction of the arrow is in the process of being discharged to the exhaust port 13 via the intake port 14 by the suction input of the exhaust fan 12 of the hood 1. A part of the exhaust gas is divided by the dividing partition 21, flows into the indoor side through the duct 22, gathers in the chamber 23, and from the chamber 23 through the discharge port 24 from the front side of the lower surface of the hood 1. It is discharged downward.
[0029]
At this time, the exhaust gas generated from the kitchen gas range 2 is easily guided to the intake port 14 side by the discharge of the exhaust gas to the discharge port 24, and the exhaust efficiency of the exhaust fan 12 is maximized thereby. The overall exhaust efficiency of the hood 1 is increased, and the indoor environment is remarkably improved.
[0030]
In addition, the gas discharged from the front side to the lower side of the lower surface of the hood 1 also serves as an air curtain that prevents the exhaust gas of the gas range 2 from flowing or diffusing indoors. is there.
[0031]
Accordingly, the gas generated from the kitchen is activated and easily discharged by the gas injected from the discharge port 24, and at the same time, it can be prevented from flowing into the room, and the combustion gas generated from the kitchen gas range 2 can be prevented. The odor of food generated when cooking a dish in the gas range 2 is completely prevented from flowing into and diffused into the room, and the indoor environment is improved.
[0032]
As shown in FIG. 4, when a side sectional view showing another embodiment of the present invention is seen, the hood 1 is configured by including a known exhaust unit 10 and an exhaust activation unit 20. The exhaust unit 10 includes an exhaust fan 12 in a case 11, an intake port 14 on the lower side of the exhaust fan 12, and an exhaust port 13 on the upper side of the exhaust fan 12. It is what is done.
[0033]
The exhaust activation unit 20 includes a partition plate 21 that vertically divides the exhaust port 13, and a duct 22 that extends from the partition plate 21 to the outside of the case 11. A chamber 23 in which a guide plate 25 is provided is provided inside the case 11, and a discharge port 24 is provided at the end of the chamber 23 so that the gas divided on the lower surface of the hood 1 is injected. It is provided and configured.
[0034]
A guide jaw 26 is attached to the end of the discharge port 24 so that the gas injected from the discharge port 24 flows horizontally.
[0035]
Accordingly, the guide jaw 26 is preferably provided in an L shape so that gas is injected horizontally along the outer surface of the intake port 14.
[0036]
Here, the gas discharged from the discharge port 24 is horizontally injected to the suction port 14 side by the guide jaw 26, thereby increasing the pressure on the outer surface of the intake port 14, and thereby the intake port 14. The pressure difference between the inside and the outside of the gas is generated. By this pressure difference, the gas formed outside the intake port 14 is easily sucked.
[0037]
Therefore, the gas exhausted from the kitchen is easily sucked into the intake port 14, whereby the exhaust power of the exhaust fan 12 is enhanced, and thereby the exhaust efficiency of the hood 1 is maximized.
[0038]
In addition, the guide jaw 26 can be variously deformed in shape, and the gas exhausted from the discharge port 24 is injected so as to contact the outer surface of the intake port 14 due to the deformation, and the guide jaw 26 is injected into the intake port 14. It is also preferable to activate the inflowing gas so that it can be easily inhaled.
[0039]
In other words, when gas is injected by the guide jaw 26 so as to contact the outer surface of the intake port 14, the gas discharged from the kitchen is attracted by the gas injected to the guide jaw 26, and the intake air can be easily obtained. It flows into the mouth 14.
[0040]
Therefore, the attraction process is generated by repeated circulation of the divided gas, thereby maximizing the exhaust efficiency of the hood 1 and significantly improving the indoor environment.
[0041]
[Industrial applicability]
As described above, the present invention divides a part of the exhaust gas discharged from the kitchen hood, discharges the divided gas from the intake port side, overactivates the exhaust, and exhausts the hood. By providing a kitchen exhaust hood that maximizes efficiency, the gas generated from the kitchen is completely discharged to prevent kitchen odors and air intake pollution, thereby purifying indoor air. is there.
[0042]
In addition, the present invention provides a kitchen exhaust hood that allows the divided gas to be easily moved from the duct to the discharge port side, thereby increasing the gas discharge speed at the discharge port. As a result, the gas generated from the kitchen is remarkably activated, and the exhaust by the hood is maximized.
[0043]
In addition, the present invention provides a kitchen hood that allows the divided gas to be discharged horizontally from the discharge port to the intake port, thereby increasing the pressure around the intake port and exhausting it from the kitchen. The gas is allowed to flow quickly to the intake port, thereby maximizing the exhaust efficiency of the hood.
