FIG. 5 is a side view showing an incision of a suction hood of a kitchen hood ventilator according to a second embodiment of the present invention.

6 is a side cross-sectional view illustrating a kitchen hood ventilator according to a second embodiment of the present invention.

5 and 6, a kitchen hood ventilator according to a second embodiment of the present invention includes a suction unit 1 and a filter unit 2, and the suction unit 1 includes a main suction unit 10, The auxiliary suction portion 11, the prevention portion 12 and the protective film 13 and the partition portion 223 may include the rotation portion 2233. [

Here, the kitchen hood ventilator according to the second embodiment includes the main suction portion 10, the auxiliary suction portion 11, the prevention portion 12 and the protective film 13 of the suction portion 1, the partition wall portion 223 Except for the configuration of the rotary part 2233, is substantially the same as that of the kitchen hood ventilator according to the first embodiment of the present invention, and thus a detailed description of the same configuration will be omitted.

Only the main suction portion 10, the auxiliary suction portion 11, the prevention portion 12 and the protective film 13 of the suction portion 1 and the rotation portion 2233 of the partition wall portion 223 will be described.

The suction portion 1 may include a main suction portion 10, an auxiliary suction portion 11, a prevention portion, and a protection film 13.

The main suction part 10 is located on the upper side of the cooking counter C and sucks the smoke, and the lower end of the front surface may be curved.

That is, the main suction portion 10 is a portion mainly sucking the smoke generated in the cooking crock (C).

In the conventional ventilating apparatus, the smoke generated in the suction unit can not be sucked into the room and may leak out to the room. To this end, the main suction unit 10 has a curved lower surface, An auxiliary suction portion 11 may be formed on the front side.

The curved surface of the main suction portion 10 can induce the discharged smoke to move to the auxiliary suction portion 11. [

The auxiliary suction part (11) is formed on the front side of the main suction part (10) and can suck the smoke flowing out from the main suction part (10). As a result, the smoke suction amount of the ventilator is improved, and the smoke that flows out to the room is not generated, so that the comfort of the kitchen can be improved.

To this end, the auxiliary suction unit 11 may include the prevention film 110, the auxiliary fan 111, and the auxiliary filter 112.

The prevention film 110 is formed on the lower side of the front surface of the auxiliary suction unit 11 so as to prevent the smoke introduced from the main suction unit 10 from flowing out to the room. The protective film 110 is formed from the ground surface

When the operation of the ventilator is turned on, the auxiliary fan 111 operates to generate a suction force in the auxiliary suction unit 11, so that the auxiliary suction unit 11 can suck the smoke.

In addition, the auxiliary fan 111 may allow the sucked smoke to flow into the filter unit 2. [

The auxiliary filter (112) is formed on the front side of the auxiliary fan (111) to filter the smoke sucked into the auxiliary suction part (11).

Accordingly, due to the smoke being sucked into the auxiliary fan 111, grease, dust or the like may adhere to the auxiliary fan 111, thereby failing to operate the auxiliary fan 111 or reducing the suction of the smoke.

Further, the auxiliary filter 112 can be attached and detached from the auxiliary suction unit 11, thereby facilitating the replacement.

The auxiliary suction unit 11 may be provided with a sensor for measuring the amount of fluid on the front side and the rear side of the auxiliary filter 112 for ease of replacement of the auxiliary filter 112. [

The controller may further include a notification unit for notifying the user when the fluid amount difference between the front side and the rear side measured by the sensor is equal to or greater than a set value.

In such a configuration, the auxiliary suction unit 11 sucks the smoke flowing out to the front side because it is not completely sucked by the main suction unit 10, so that the smoke may not flow out into the room.

The prevention part (12) is formed on the rear side of the suction part (1) to prevent formation of grease on the wall of the kitchen.

For this purpose, the prevention part 12 includes the fan 120 so that the wind is blown downward so that the smoke generated in the cooking counter C can be sucked into the suction part 1 without touching the wall.

The fan 120 may be formed on the upper side of the inside of the prevention part 12 and when the operation of the ventilation device is turned on, the fan motor 121 may be operated and rotated by the fan motor 121.

The protection film 13 may be formed to be inclined rearward from the rear surface of the suction unit 1 so as to prevent the smoke from flowing into the prevention unit 12. [

In addition, the area of the path of the air blown by the prevention part 12 narrows toward the wall from the lower end side of the prevention part 12, so that the speed of air blown can be improved.

This prevents smoke from being introduced into the preventing portion 12 and prevents oil, dust, and the like from sticking to the inside of the preventing portion 12, thereby improving the speed of the air to be blown and preventing the smoke from reaching the wall Can be further improved.

The partition wall portion 223 may include a rotation portion 2233.

The rotating portion 2233 can rotate the demister filter in the downward direction. To this end, the rotating portion 2233 may include a rotating shaft and a motor (not shown).

The rotation axis may be formed parallel to the demister filter 224 on the partition wall portion 223 and connected to the first filter 2240 or the second filter 2241.

The rotation axis of the first partition 2230 may be formed in the first partition 2230 and the second partition 2231 of the partition 223, And the rotation axis formed on the second bank 2231 may be connected to the second filter 2241. [

A motor (not shown) can rotate the rotary shaft.

Accordingly, when the sucked smoke is discharged to the discharge port 24 and the operation of the ventilator is turned off, the demister filter 224 is rotated by the rotating portion 2233 to remove foreign substances accumulated on the upper side of the demister filter 224 Can be removed.

At this time, the water injector 221 may operate for a predetermined time even after the operation of the ventilator is turned off to spray water to the demister filter 224, so that the foreign matter can easily fall off from the demister filter 224.

Also, after the predetermined time has elapsed, the water injection device 221 stops and the rotation part 2233 rotates the demister filter 224 to return to the original position, and the operation can be stopped.

With this configuration, the life of the demister filter 224 can be prolonged, and the demister filter 224 can be used in a clean state, thereby improving the filter efficiency.

As described above, the hood ventilator according to the embodiment of the present invention sucks and filters fine dust, oil, odor, and carbon monoxide included in the smoke and the smoke generated in the cooking process on the upper side of the cooking pad in the kitchen, Can be discharged. Accordingly, it is possible to cook in a pleasant environment, and smoke, fine dust, oil, odor, and carbon monoxide are not discharged to the ventilating ducts outdoors, thereby preventing unpleasant odors due to debris adhering to the ventilating ducts and replacement of ventilation ducts There is an advantage that a separate operation of time, cost and time are not required.

In addition, since clean air is discharged outdoors, it may not be harmful to the environment.

In addition, the dust collector can be used without being replaced, which is economical.
