Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a domestic range hood used in a kitchen, and more particularly to a range hood with a deodorizing function for eliminating cooking odors.

[0002]

2. Description of the Related Art Steam and oil smoke generated during cooking have been discharged outdoors by a ventilation fan, but in recent years, it has been desired to discharge the odor contained in steam or oil smoke after deodorizing it. A range hood using activated carbon or ozone as a deodorant is known for a home kitchen.

[0003]

However, in the range hood using activated carbon as the deodorant, the activated carbon exerts an effect on oil and water vapor, and therefore has a short life. Requires frequent replacement of activated carbon. On the other hand, a range hood that uses ozone as a deodorant requires careful handling and maintenance because ozone is toxic.

The present invention has been made in view of the above facts, and its object is to easily handle and
It is to provide a range hood having a good deodorizing function for a long period of time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory diagram showing a main part of a range hood with a deodorant function according to a first embodiment of the present invention.

As shown in FIG. 1, the range hood of the present invention is installed above a cooker 7 such as a gas stove in a kitchen. In the range hood, a suction port 1 is provided above the cooking device 7, and steam and oil smoke sucked from the suction port 1 are guided into the range hood through a ventilation path 2. The range hood includes a water tank 3, and the tip of the ventilation passage 2 reaches the inside of the water 6 stored in the water tank 3.
A discharge port 4 is provided above the water surface of the water storage tank 3, and a ventilation fan 5 is provided at the discharge port 4.

Steam or oily smoke containing odorous components generated during cooking is introduced from the suction port 1 into the water through the air passage 2, and the odor and steam dissolve in the water 6. It is preferable that the water 6 contains a surfactant because a more lipophilic odor can be dissolved therein. The air in which the odorous component is dissolved in water is discharged to the outside from the discharge port 4 by operating the ventilation fan 5.

Next, another embodiment will be described.
FIG. 2 is an explanatory view showing a main part of a range hood with a deodorant function according to a second embodiment of the present invention. The range hood with a deodorant function includes, in addition to the above-described configuration, a water supply passage 8 for supplying water to the water storage tank 3 and a drainage passage 9 for draining the water 6 in the water storage tank 3. Tap water can be used as the above water, and the water 6 is stored in the water storage tank 3 through the water supply passage 8 by opening the faucet 11. It is preferable to provide heating means 10 such as a gas water heater or a gas stove in the middle of the water supply passage 8 to heat the water. When water is heated, the oil content becomes 6
As it dissolves better, the deodorant function is more effective. When the water 6 in the water storage tank 3 becomes dirty, the valve 12 at the bottom of the water storage tank 3 is opened and the water is discharged from the drainage channel 9.

Further, for example, in the above range hood, if a water supply channel (not shown) is provided up to the ceiling of the range hood and flush water is allowed to flow to the ventilation channel 2 and the wall surface of the suction port 1, the ventilation channel 2 The oil and odor adsorbed on the wall surface of the suction port 1 can be washed away. The washed water is discharged through a drain groove 14 formed by a gutter-shaped projection piece 13 provided on the wall surface of the suction port 1.

(Experimental example) Using the above range hood, tap water at 15 ° C, tap water heated to 40 ° C in the water tank 3
The degree of deodorization was measured when using an aqueous solution containing 5% by weight of soap powder in tap water at 0 ° C. and when the water storage tank 3 was empty.

The measurement was performed as follows. The fish was grilled on the stove and the air discharged from the outlet was collected. The odor level was measured by the three-point comparison odor bag method by eight panelists, and the maximum and minimum values of the data were cut off, and the remaining average value was calculated. As shown in Table 1, it was confirmed that the range hood with a deodorant function of the present invention is effective.

[0017]

[Table 1]

[0018]

The range hood with a deodorant function according to claims 1 to 4 of the present invention has the above-mentioned configuration, and by utilizing the water in the water storage tank, the odorous component of steam or oil smoke generated during cooking. Dissolves in water and is deodorized, so that it is easy to handle and can exhibit a good effect for a long period of time.

The range hood with a deodorant function according to claim 2 of the present invention has, in addition to the above effects, particularly a water supply channel and
Since it has a drainage channel, it is easy to exchange water and a good effect can be exerted at any time.

In addition to the above effects, the range hood with a deodorant function according to claim 3 of the present invention contains a large amount of oil, in particular, since water contains a surfactant, the oil dissolves better. Effective for deodorizing oily smoke.

In the range hood with a deodorizing function according to the fourth aspect of the present invention, since the water is heated particularly because of the above structure, the oil content is better dissolved, so that the deodorizing function is more effective.
