Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention relates to a cooking table for a restaurant,
The present invention relates to an exhaust device that performs processing such as deodorization, deodorization, and sterilization of gas such as smoke generated from a stove or a smoking room with ozone.

[0002]

2. Description of the Related Art Generally, an exhaust device provided in a restaurant or the like sucks smoke with a fan 2 as shown in FIG.
It was discharged as it was outdoors.

Further, as an exhaust device for removing smoke and removing dust, there is a device that allows smoke sucked by a fan 4 to penetrate into water 6 as shown in FIG.

[0004] Further, as shown in FIG. 8, there is an exhaust device in which a (+) electrode 10 and a (-) electrode 12 facing each other are provided inside a chimney 8, and a high voltage is applied between the electrodes to deodorize. Was.

[0005]

In the exhaust device shown in FIG. 6, there is a problem that the smoke is merely discharged to the outside, which affects the outdoor environment.

In addition, the exhaust device shown in FIG. 7 requires a water tank or the like, which causes a problem that the size of the device is increased and deodorization is difficult.

Further, in the exhaust device shown in FIG. 8, the cost of the device is extremely high, and it has been difficult to add the device to an existing device such as a duct.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an exhaust device which can remove gas, deodorize, and sterilize gas and can be attached to an existing duct.

[0009]

An exhaust device according to the present invention has a duct for introducing a gas to be exhausted, and is disposed in the duct, and is disposed near a cylindrical electrode and one opening of the cylindrical electrode. A first ozone generation unit having an ozone generating electrode composed of a needle electrode and discharging ozone air in a direction in which the gas flows, a needle disposed near the cylindrical electrode and one opening of the cylindrical electrode A second ozone generation unit having an ozone generation electrode composed of an oval-shaped electrode, disposed opposite to the first ozone generation unit, and flowing out an ozone wind in a direction opposite to the flow of the gas; And an electronic unit for applying a high voltage to each of the two ozone generating units.

[0010]

In the exhaust device of the present invention, the gas introduced into the duct is exposed to the ozone air generated by the first and second ozone generating units from the front and rear directions of the gas flow, thereby eliminating smoke and deodorizing. And sterilized and discharged.

[0011]

FIG. 1 is a sectional view showing an exhaust device according to an embodiment of the present invention. Reference numeral 14 denotes a duct, into which exhaust gas such as smoke is introduced by a fan or the like, and flows from left to right in the figure as indicated by an arrow 16.

Reference numerals 18 and 20 denote first and second ozone generating units which are detachably installed in the duct 14, and are opposed to each other at a predetermined interval. The first and second ozone generation units 18 and 20 are provided with bases 22 and 2
4, ozone generating electrodes 26 and 28 attached to bases 22 and 24 to generate ozone wind, respectively, and base 2
Filters 30 and 3 attached to 2, 24 respectively
And 2. The ozone generation electrodes 26 and 28 used in the first and second ozone generation units 18 and 20 have a substantially cylindrical shape made of plastic or the like compatible with the duct 14, as shown in FIGS. The case 34 includes a plurality of cylindrical electrodes 36 arranged in a ring shape within the case 34, and needle electrodes 38 arranged near one opening of each cylindrical electrode 36. . As shown in FIG. 5, the filters 30 and 32 have a honeycomb shape and remove dust, oil, water vapor, and the like contained in gas. In addition, as shown in FIG.
Numeral 2 is arranged in a direction in which gas flows into the ozone generating electrodes 26 and 28, respectively.

In FIG. 1, reference numerals 40 and 42 denote electronic units for generating a DC high voltage and applying the DC high voltage to the cylindrical electrode 36 and the needle electrode 38 of the first and second ozone generating electrodes 26 and 28.

In the exhaust device having the above configuration, when gas such as smoke is introduced into the duct 14, first, dust and the like are removed by the filter 30 of the first ozone generation unit 18. Next, the gas passes through the center hole 44 (FIG. 3) of the case 34 and the like, and the first and second ozone generation units 1
It flows between 8 and 20. At this time, the ozone generating electrode 2
A high DC voltage is applied to each of the cylindrical electrodes 36 and 28 and the needle electrodes 38, and corona discharge occurs between the electrodes, and ozone wind is generated by the discharge energy at this time. The ozone air flows outward from the opening of the cylindrical electrode 36 on which the needle electrode 38 is not disposed. Therefore, in the present embodiment shown in FIG. 1, the ozone wind generated at the ozone generating electrode 26 flows out rightward in the figure, and the ozone wind generated at the ozone generating electrode 28 flows leftward in the figure. As a result, the space between the first and second ozone generating units 18 and 20 is filled with ozone and stagnates, and the gas that has passed through the filter 30 flows into the unit and is deodorized, deodorized, and sterilized by the ozone. The gas thus treated is further discharged rightward in the figure through the filter 32 and the ozone generating electrode 28 and exhausted.

When the filters 30 and 32 are replaced or cleaned, a part of the duct 14 is removed and opened to open the first and second ozone generating units 18 and 20 installed inside.
Remove, replace and clean.

In this embodiment, the filter 3
Although the first and second ozone generation units 18 and 20 having different positions of 0 and 32 are used, only one of the first and second ozone generation units 18 and 20 is used so that they are opposed to each other. May be.

Further, in this embodiment, the first and second
Although the electronic units 40 and 42 are provided for the ozone generation units 18 and 20, respectively, they may be integrated. Furthermore, the connection paths between the electronic units 40 and 42 and the ozone generation electrodes 26 and 28 are subdivided and made switchable, so that the numbers of the cylindrical electrodes 36 and needle electrodes 38 to which a voltage is applied are switched, and the ozone It is also possible to adjust the amount of generated gas to efficiently process gas.

[0018]

According to the present invention, a section is provided between the first and second ozone generating units in the duct where the ozone is filled and stagnated, and gas is introduced into the section for processing. It is possible to deodorize, deodorize, sterilize and exhaust at once without interrupting the gas flow.

Further, since the first and second ozone generation units are small and unitized, all the devices can be housed in the existing duct, and furthermore, cleaning and replacement are easy and quick. Can be performed.
