2. Description of the Related Art As a device for deodorizing and sterilizing a room or the like, there is a device in which an air blower is combined with an ozone generator. In this device, the ozone (O
By releasing 3) into the air by a blower fan, deodorization can be performed by the oxidizing action of the ozone, and sterilization can be performed by the cell membrane destructing action.

[0003]

However, in the above apparatus, since ozone is only carried by the airflow from the blower fan, it is difficult to carry and diffuse ozone to a desired area, and the desired deodorizing and sterilizing effects are obtained. There is a difficulty that is difficult to obtain.

[0007]

According to the first aspect of the present invention, when the pump and the ozone generator are operated after heating the vaporizer main body to a predetermined vaporization temperature with heater heat, the vapor liquid in the liquid storage tank is supplied. The liquid is sent into the vaporization chamber of the vaporizer main body through the liquid pipe and vaporized, and the vapor is blown out from the discharge nozzle. A negative pressure based on the Venturi action is generated at the tip of the outlet nozzle by the blown steam, and the ozone generated by the ozone generator is sucked up to the tip of the outlet nozzle through the ozone guide pipe by the negative pressure. Then, the sucked ozone is mixed with the blown-out steam, and liquid fine particles containing ozone are blown out in a predetermined direction.

In the ozone jetting device according to the second aspect, when a negative pressure is generated at the tip of the outlet nozzle due to the Venturi action, the atomizing liquid in the second liquid storage tank is discharged through the second liquid supply pipe. It is taken into the outlet pipe, mixed with ozone, and sucked up at the tip of the outlet nozzle. Then, the mixed liquid collides with the ejected vapor and is atomized, and liquid fine particles containing ozone are ejected in a predetermined direction.

A liquid supply pipe 11 has a lower end inserted into the second liquid storage tank 10 and an upper end connected to the middle of the ozone guide pipe 7.

Reference numeral 12 denotes an ejection control circuit having a microcomputer structure, and the pump 3, the heater 4f, and the temperature sensor 4 described above.
g and the ozone generator 6 and the operation switch 13 are connected. The ejection control circuit 12 stores a control program in a memory, controls the heater 4e on / off based on a detection signal of the temperature sensor 4e, and maintains the temperature of the vaporizer 4 at a predetermined vaporization temperature. , Pump 3 and ozone generator 6 are controlled.

Here, the operation of the above-described ozone ejection device will be described with reference to FIG. Operation switch 13 after power-on
Is turned on, energization of the heater 4f of the vaporizer 4 is started, and the vaporizer body 4d is heated (S1, S1).
2). When the vaporizer temperature T detected by the temperature sensor 4g by this heating rises to a temperature suitable for instantaneous vaporization of the vapor liquid F1, for example, 180 ° C., the operation of the pump 3 and the ozone generator 6 is started ( S3 to S5).

As a result, the vapor liquid F1 in the first liquid storage tank 1 is fed into the vaporization chamber 4c of the vaporizer body 4d through the first liquid supply pipe 2 and vaporized, and the vapor is blown out from the jet nozzle 5. You. A negative pressure based on the Venturi action is generated at the tip of the discharge nozzle 8 by the blown steam, and the ozone generated by the ozone generator 6 is sucked up by the ozone guide pipe 7 by the negative pressure. The atomizing liquid F2 is taken into the ozone derivation pipe 7 through the second liquid supply pipe 11, and a mixture of the atomization liquid F2 and ozone is sucked up to the tip of the derivation nozzle 8. Then, the sucked-up mixed liquid collides with the blown-out steam to be atomized, and fine particles of water containing ozone are jetted in a predetermined direction.

Until the operation switch 13 is turned off, the vaporizer temperature T at the time of this ejection is set to approximately 180 ° C. by controlling the energization of the heater 4f on / off based on the detection signal of the temperature sensor 4g.

As described above, in the above-described ozone ejecting apparatus, the vaporized liquid F1 is vaporized in the vaporizer 4 and the vapor is ejected from the ejecting nozzle 5, so that a mixed liquid of the atomizing liquid F2 and ozone is discharged from the nozzle. 8, the atomized water is atomized and ejected together with the steam, so that ozone can be carried on the fine particles of water and conveyed accurately in the jetting direction of the fine particles. Can be done properly.

Further, ozone and the atomizing liquid F2 are mixed in the suction process, and the mixed liquid is sprayed to be atomized by steam. Therefore, ozone is almost uniformly mixed with fine particles of water to be jetted. The above deodorization and sterilization can be performed evenly.

In the above-described embodiment, the second storage tank and the second liquid supply pipe are provided, and the ozone generated by the ozone generator and the atomizing liquid are mixed in the suction process. However, the same operation and effect can be exerted even if the configuration of the second liquid storage tank and the second liquid supply pipe is excluded and ozone is directly guided to the tip of the lead-out pipe. Further, the ozone generator exemplified in the embodiment may be other than the silent discharge type. Further, as the liquid for atomization, a liquid other than water and purified water, for example, a liquid mixture of powdered activated carbon dispersed in water or a liquid containing a deodorant component can be used. By doing so, the deodorizing / sterilizing effect can be enhanced in cooperation with ozone.

[0023]

As described in detail above, according to the ozone ejecting apparatus according to the first aspect, ozone is discharged from the ejecting nozzle by evaporating the vapor liquid in the vaporizer and ejecting the vapor from the ejecting nozzle. Since it can be sucked to the tip and mixed with the blown-out steam, ozone can be carried on the fine particles of water and transported accurately in the direction in which the fine particles are ejected, and deodorization and sterilization of a desired area can be appropriately performed.

According to the second aspect of the present invention, there is provided an ozone ejecting apparatus.
In addition to the above effects, ozone and the atomizing liquid can be mixed in the suction process and the mixed liquid can be blown out and atomized with steam. Can be performed evenly.
