The illuminator 10 is preferably provided with a triangular water leakage preventing means (10a) can further prevent the discharge of water.

In FIG. 1, the ozone treatment unit 7 is installed almost horizontally from the suction unit 8, and water particles 16a are formed vertically downward in a region in which the cooking exhaust flows upward, so that the water after treatment is discharged downward. The spray nozzle 16 is installed. In this manner, the suction part 8 and the ozone treatment part 7 are installed to penetrate the range hood from inside to outside horizontally through the wall of the building, and extend from the end of the ozone treatment part 7 to the wall of the building. The screen 9, the area of the water particles 16a, the spray nozzle 16, the eliminator 10 and the discharge part 6 are installed in the body vertically upward along the outside of the body. By installing the discharge pipe 17 and the water tank 2 to be described later, it is possible to use only the minimum indoor space and at the same time maximize the buoyancy of the cooking exhaust and the gravity of the water particles downward to maximize the decontamination efficiency and energy saving. You can do it. However, the present invention is not limited to this arrangement structure, and the ozone treatment unit 7 may be configured such that treatment with ozone is performed while the cooking exhaust flows vertically, and sprayed while the cooking exhaust flows horizontally. Spray nozzle 16 and the body 3 may be configured to be treated by the water particles to be.

However, the ozone treatment unit 7 is provided upstream, and the water particles 16a are installed downstream, thereby preventing the ozone from being released into the atmosphere.

In FIG. 1, the water tank 2 is installed under the portion where the ozone treatment unit 7 is connected as a lower part of the spray nozzle 16 installed in the body 3, which is a vertical duct, and cooks for efficient discharge of the cooking exhaust. The lower part of the body 3 forming the passage of the exhaust is sealed, and the discharge pipe 17 is connected so that water containing oil, which is collected at the bottom thereof, is discharged to the water tank 2 through the discharge pipe 17. desirable.

The water tank 2 is provided with a filter 21 at the inlet portion to filter dust and the like, and remove oil such as a sliding screen net or an oil separator so as to solidify and remove an oil component in the upper portion of the water tank 2. It is preferable that the means 22 be provided, and furthermore, in order to facilitate coagulation, it is preferable to configure the coagulant to be administered together with the water supplied as necessary or from the top of the water tank 2.

In addition, it is preferable that the water tank 2 is provided with drain means for waterproofing to the outside as needed.

Reference numeral "1" may be installed to fix the above-described water tank 2, the body 3, etc. as a frame, and may include a fixed installation structure such as the water tank 2, the body 3, etc. It may be.

When described in detail with reference to Figure 1 the operation of the kitchen exhaust deodorizing device according to an embodiment of the present invention is configured as follows.

First, the cooking exhaust collected through the range hood is mixed with ozone of the ozone generator 15 supplied to the ozone treating unit 7 while flowing into the ozone treating unit 7 through the suction unit 8, in particular, a turbulence forming unit ( 7a), the turbulent flow is increased, and the mixing effect is increased, and the smell and the like are oxidized and deodorized by the ozone and deodorized by the ozone. It is preferable that the amount of ozone supplied from the ozone generator 15 be configured to be adjusted according to the component or the exhaust amount of the cooking exhaust together with the amount of the water particles 16a and the blowing amount of the fan 14.

In the spray nozzle 16, the water supplied through the water supply pipe 12 by the pump motor 13 is ejected into the water particles 16a downward in the body 3, and this water is transferred to the screen 9. As it is dipped downward or flows down the inner wall of the body 3, as described above, the ozone-treated cooking exhaust passes through the screen 9, and oxidizes dust, oil, and the like which are oxidized and decomposed by ozone. Undecomposed dust, oil, etc. are first filtered out, and excess ozone is also dissolved in water and removed from water moistened with the primary screen 9 or water flowing through the inner wall of the body 3. 9) or water containing contaminants flows downward from the inner wall of the body 3 downward.

In addition, the cooking exhaust flows upwardly, that is, downstream, and passes through the water particles 16a, so that the remaining dust, oil, ozone, etc. are almost completely dissolved in water, adhered to, or condensed, and flow downward. Dust, etc. are removed and deodorized. In particular, in the case of ozone, for example, 10 lpm (liter per minute) of the cooking exhaust is oxidatively decomposed to 100 ppm of ozone, and then all ozone is dissolved by 3 lpm of mist 16a. Was not discharged.

In this way, the cooking exhaust that has passed through the water particles 16a is almost completely removed from oil, dust, ozone, and the like, but depending on the processing flow rate, the higher the flow rate, the more contaminated the cooking exhaust that has passed through the water particles 16a. Fine moisture remains. This water is also completely removed as it passes through the downstream eliminator 10 and flows downward. Although the number of stages of the eliminator 10 differs depending on the flow rate, in the experiment, the standard of 45 degrees and 5 cm x 5 cm was performed in 3-5 stages.

After doing this, a three-point comparative method of collecting by six odor judges, who have no sense of smell, is determined by the odor sensor or smells and determines the smell. Method of evaluating the presence of odor from three plastic bags) or gastec detection tube (determining the presence or absence of odor by discoloration of the test substance when inhaled with a syringe from the pollutant and contacting the test substance in the tube) As a result of measuring the effect by the pipe containing the test substance in the method, the removal efficiency was much higher in the case of treatment with only the water particles 16a than in the case where only the ozone treatment unit 7 was operated. When treated together with water particles (16a), the removal efficiency of odor was the highest, and most of the bad cooking conditions were also over 90%.

Further, as can be seen from the detailed illustration of FIG. 1, when the water leakage preventing means 10a is installed at the end of the eliminator 10, it is possible to almost completely prevent the release of water, and moreover, to prevent the leakage of water in a triangle shape. The means 10a were more effective.

On the other hand, contaminated water falling in the body 3 or flowing downward along its inner wall flows to the water tank 2 through the discharge pipe 17 at the bottom of the body 3. In the water tank 2, dust and the like in the water are removed through the filter 21 installed at the inlet, and in the water tank 2, oil which is solidified and suspended by the temperature of the water or a coagulant is oil such as a screen net or an oil separator. It is filtered by the removal means 22, and the oil removal means 22 is taken out to the outside, and only the oil component is collected and treated separately, so that the water in the water tank 2 can be purified to the extent possible to discharge.

In this way, when the water in the water tank 2 is purified, the above-described embodiment of the present invention is configured to reuse the purified water below the water particles 16a, but is not necessarily limited thereto. It is preferable that a pipe is provided so that clean water can be supplied to the water tank 2 as needed.

According to the configuration and action of the kitchen exhaust deodorization apparatus according to the embodiment of the present invention described above, the efficiency of removing odors and dust from the cooking exhaust is high, and only the present invention having such efficiency meets the air air purification method to be strengthened. Not only can be made, but also has a simple structure and easy installation, such as suitable for being employed as a kitchen exhaust deodorizer.
