The opening and closing plate 23 for the ventilation is about the opening and closing angle of the cooking opening and closing plate 13 so that it can be easily opened by the wind pressure passing through the cooking opening and closing plate 13 due to the rotation of the cooking fan motor 11. It is formed to intersect 90 degrees.

Reference numeral 40 is a partition installed at the boundary of the lower case 10 and the upper case 20, the cooking fan motor 11 and the ventilation fan motor 21 is installed.

Hereinafter, the method of using the range hood according to the present invention according to the accompanying drawings as follows.

As shown in Figure 2 and 5, when cooking or cooking food using the range (1), the harmful gas including the food smell, heat, and the like rising vertically to the hood body 30, the hood body 30 It spreads around the left and right sides of the) and can inhale harmful air including stagnant food odor, dust, etc. under the ceiling (3) and discharge it to the outside.

That is, the cooking fan motor 11 installed in the chamber 14 of the lower case 10 as described above may be adjusted in multiple stages to adjust the cooking conditions (eg, types of food, heat, concentration of food smell, etc.) of food. In the case of rotating by adjusting the rotational speed, the harmful gas including the smell of food rising vertically toward the hood body 30 when food is cooked is lowered by the suction force of the cooking fan motor 11. After being sucked into the chamber 14 through the first inlet (10a) formed on the bottom surface of the), opening and closing the upper side of the exhaust port 12 communicated with the chamber 14 by the discharge force of the cooking fan motor 11 It is possible to open the cooking opening and closing plate 13, which is hinged and fixed, by wind pressure.

At the same time, the hood main body 30 when cooking food by the suction power of the ventilation fan motor 21 by rotating the ventilation fan motor 21 installed in the chamber 24 of the upper case 20 at a predetermined speed. After inhaling harmful air containing the food odor, moisture, etc. stagnating under the ceiling (3) inside the upper case (20), the ventilation fan motor (21) and the cooking fan motor (11) By opening the ventilation opening and closing plate 23 installed in the exhaust port 22 in communication with the chamber 24 by the discharge force of the opening, the harmful air sucked in the upper case 20 and the lower case 10 It can be discharged through the exhaust hole (2) communicated to the outdoors.

When the cooking opening / closing plate 13 described above is opened by the wind pressure passing through the exhaust port 12, the stopper 15 formed at the end of the partition 40 formed at the boundary between the upper and lower case 20 and 10 is provided. Since the cooking opening and closing plate 13 is prevented from being opened beyond the set angle, the cooking opening and closing plate 13 can be prevented from being damaged.

On the other hand, as the lower edge of the inside of the exhaust port 12 communicating with the chamber 14 of the lower case 10 is formed in a concave curved shape, harmful gas sucked into the chamber 14 passes through the exhaust port 12. When discharged to the exhaust hole 2 along the concave curved surface, it is possible to prevent the stagnation due to the vortex formation in the inner corner of the exhaust port (12).

On the other hand, as shown in Figures 2 and 4, so that the opening and closing angle of the above-mentioned cooking opening and closing plate 13 and the opening and closing angle of the ventilation opening and closing plate 21 to cross (for example, say 90 degrees). As formed, even when the cooking fan motor 11 is rotated, the cooking opening and closing plate 13 and the ventilation opening and closing plate 23 are sucked by the lower case 10 and discharged to the exhaust hole 2 by the wind pressure. It can be easily opened.

Therefore, when cooking the food by rotating the above-described cooking fan motor 11 and the ventilation fan motor 21 at the same time, the harmful gas containing the food smell vertically rising toward the hood body 30, the ceiling By inhaling the smell of food containing contaminated air in (3) and then discharging it to the outside, the ventilation efficiency can be doubled to maintain a pleasant indoor environment without food smell at all times.

On the other hand, as shown in Figures 2 and 6, when food is not cooked, according to the pollution degree of the indoor air by rotating only the above-described ventilation fan motor 21 without opening the window to contaminated air in the room By ventilating to realize a pleasant kitchen culture, it is possible to save heat energy when cooling or heating.

When the above-described ventilation fan motor 21 rotates at a high speed or a low speed, it sucks and discharges harmful air including contaminated air, dust, moisture, etc. on the ceiling side 3 by suction force, but the ventilation fan motor 21 Due to the rotation of the exhaust through the second suction port 20a formed on the upper surface of the upper case 20 from the ceiling (3) harmful air sucked into the hood body 30 is connected to communicate with the exhaust port 22 (2) can be discharged to the outdoors.

That is, when the ventilation fan motor 21 installed in the chamber 24 of the upper case 20 is rotated at a predetermined speed (at this time, the cooking fan motor 11 is not rotated). When cooking food by suction power of fan motor 21, harmful air including food smell, moisture, etc. stagnated under the ceiling 3 and spreading around the left and right sides of the hood body 30 is sucked into the upper case 20. After that, the ventilation opening and closing plate 23 provided to be opened and closed in the exhaust port 22 communicating with the chamber 24 is opened by the discharge force of the fan motor 21 for ventilation, so that it is sucked into the upper case 20. It is possible to discharge the harmful air through the exhaust hole (2) communicated to the outside.

At this time, since the above-described cooking opening and closing plate 13 maintains the closed state, the harmful air is sucked from the ceiling 3 into the upper case 10 due to the rotation of the fan motor 21 for ventilation, and the exhaust port 12 When it is discharged to the exhaust hole 2 through) it can be prevented from flowing back to the lower case (10).

Therefore, when the food is not cooked, only the above-described ventilation fan motor 21 is rotated separately to reduce noise and vibration by inhaling harmful air including stagnant dust under the ceiling 3 to the outside after inhalation. In other words, the electricity bill can be reduced.

On the other hand, contaminated air, such as a food odor, is caused in the chambers 14 and 24 of the lower case 10 and the upper case 20 due to the rotation of the cooking fan motor 11 or the ventilation fan motor 21 described above. After each of the suction and discharged through the exhaust holes 12 and 22 communicating with the chambers 14 and 24 to the exhaust hole 2 communicating with the outside, the cross-sectional shape of the aforementioned hood body 30 is a snail shape. As the cross-sectional area of the discharge side opening is larger than the cross-sectional area of the suction side opening of the chambers 14 and 24, the amount of air discharged from the chambers 14 and 24 to the exhaust hole 2 can be increased.

In addition, when a gas and food smell are detected by installing a mixed gas sensor at one side of the kitchen, the gas and food smell are quickly discharged due to the operation of the cooking fan motor and the ventilation fan motors 11 and 21. Of course, safety accidents can be prevented.

As mentioned above, according to a preferable embodiment, it has the following advantages.

Cooking fan motor that inhales odor generated from food depending on cooking status of food and ventilation fan motor selectively rotates to discharge harmful air including stagnant dust under the ceiling and then to outside. And minimizing the generation of vibration, and can reduce the power consumption by reducing the power consumption.

In addition, a first intake port through which the smell of food, etc. is inhaled, and a second intake port through which harmful air under the ceiling are sucked are arranged on a vertical line, and the opening cross-sectional areas of the first intake port and the second intake port are extended to flow into the hood body. The suction efficiency can be improved by increasing the amount of air flow and the pressure of air.

In addition, it is possible to improve the workability of manufacturing and assembling them by detachably forming the hood body in which the cooking fan motor and the ventilation fan motor are installed in the upper and lower cases.
