DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifying apparatus which is installed mainly on cooking equipment in a kitchen and which purifies and exhausts air to be purified such as oily smoke generated during cooking.

[0002]

2. Description of the Related Art In recent years, an air purifying apparatus that suctions, purifies, and exhausts air to be purified, such as oil smoke generated during cooking in a kitchen or the like, has become widespread even at home. This type of air purification device is generally called a range hood, and is installed above a range base, which is cooking equipment provided in a kitchen.

In the above-mentioned air purifying apparatus, for example,
A short slit-shaped opening 3a, 4a (not shown) made of a metal plate material such as a stainless steel as shown in FIG. The two perforated plates 3 and 4 arranged in a row are connected to the respective openings 3a and 4a and the non-openings 3b and 4 other than the same openings.
b (not shown) in parallel with each other so as to face each other.
Are formed. Then, air to be purified such as oil smoke generated during cooking is sucked through the above-described ventilation path by the intake fan provided in the hood main body, and is ventilated to the perforated plates 3 and 4 to purify the air and through the air duct. Exhaust to the outside.

Therefore, in the perforated plates 3 and 4,
The oil component having a large mass in the air to be purified is accelerated at the opening 3a of the first perforated plate, collides with the second non-opening 4b, and is captured and purified. The oil components adhering to the surfaces of the perforated plates 3 and 4 need to be cleaned and washed off at regular intervals using a detergent or the like.
Many of the purifying units 2 are installed in the air purifying apparatus 1 at an angle as shown in FIG.
An oil pan C is provided for collecting and collecting the captured oil components. Therefore, most of the trapped and collected oil is collected in the oil receiver C and discarded.

[0005]

However, in the above-mentioned prior art, in order to prevent a decrease in air purification performance due to a decrease in air volume due to clogging of the purification section, the user must make the perforated plates 3, 4 at regular intervals.

Have been. In addition, an ultrasonic vibrator 14 is provided at the bottom for more effectively cleaning with the cleaning liquid.

In the air purifying apparatus 1, when the purifying operation is completed, the drive motor 7 is driven to drive the purifying section 2
To rotate. At this time, the ultrasonic vibrator 14 is also driven, and the cleaning liquid is finely vibrated, and the oil component in the air to be purified captured by colliding with the non-opening portion 4b of the perforated plate 4 is decomposed and separated, thereby purifying. During operation, oil or the like that has adhered to the surfaces of the perforated plates 3 and 4 of the purification unit 2 does not adhere and accumulate. In this case, by rotating and driving the purification unit 2 to which the water-repellent paint is applied, the oil component can be decomposed and separated. In this case, the water level sensor 13 easily detects a decrease in the water level of the cleaning water, and the water supply valve 84 is operated to automatically supply water.
Based on a preset accumulated time condition under which the cleaning effect of the cleaning water is reduced, the contaminated cleaning water is drained by operating the drain valve 86 every predetermined time, and thereafter,
The water supply valve 84 and the pump 89 are operated to newly supply and maintain the wash water and the detergent.

Therefore, according to the air purifying apparatus described above, the purifying section 2 for purifying air is provided in the air passage A of the hood body 5, and the air to be purified is sucked by the intake fan 6 through the air passage A. At least two perforated plates 3 and 4 of an air purifying apparatus 1 that ventilates and purifies and exhausts air are disposed such that openings 3a and 4a and non-openings 3b and 4b of each perforated plate face each other. The purifying unit 2 is rotated and driven,
Since the oil and the like adhering to the purifying unit are cleaned in the cleaning tank 82 below the purifying unit during the purifying operation, the oil component adhering to the purifying unit 2 is easily decomposed and removed without bothering the user. Therefore, usability can be improved.

Further, since the purifying section 2 coated with the water-repellent paint is driven to rotate, the oil component adhering to the purifying section 2 can be more reliably decomposed.
