Description

  The present invention relates to an ozone mist generator, and more particularly to an ozone mist generator that can enhance the effect of ozone by controlling the ozone concentration.

  Conventionally, various effects such as sterilization (sterilization) effect and deodorization effect of ozone are known. It is also known that ozone gas or ozone water can be generated by ozonizing air or water by an ultraviolet lamp or electrolysis. In addition, humidifiers have also been used in the past for measures against winter drying. Humidification using a humidifier can eliminate skin problems caused by drying and inactivate certain viruses.

  In order to make use of both of these characteristics, proposals have been made to generate ozone mist by misting ozone water (see, for example, Patent Document 1). According to this, water sent by capillary action is ozonized by a U-shaped ultraviolet lamp and misted by an ultrasonic humidifier.

JP 2006-35009 A

  However, since the efficiency at the time of ozonizing water with an ultraviolet lamp is not so high, there are cases where high disinfection effect and deodorization effect by ozone mist cannot be expected. Therefore, when a higher sterilizing effect and deodorizing effect are required, a sufficient ozone concentration can be obtained by simply ozonizing the fed water with an ultraviolet lamp, as disclosed in Patent Document 1. In some cases, the ozone effect was insufficient.

  The present invention has been made in view of the above circumstances, and by controlling the ozone concentration, the concentration can be increased as necessary, and humidification is also achieved while enhancing the effects of sterilization, deodorization and the like by ozone. It is an exemplary problem to provide an ozone mist generator that can be performed.

  In order to solve the above problems, an ozone mist generator as an exemplary aspect of the present invention includes a water storage tank that stores water therein, and an apparatus main body that includes an ultraviolet lamp that ozonizes water in the water storage tank; And a mist generating means for atomizing ozonized water to produce ozone mist, wherein the water storage tank accommodates an ultraviolet lamp and covers the surrounding area of the ultraviolet lamp. An ultraviolet lamp storage chamber disposed in the chamber, a merging means for combining ozonized air ozonized by the ultraviolet lamp in the ultraviolet lamp storage chamber with the ozone mist, and a discharge port for discharging the ozone mist. The apparatus main body has an attachment / detachment sensor that detects attachment / detachment of the water storage tank.

  Since the water storage tank has the ultraviolet lamp storage chamber, the water in the water storage tank can be efficiently irradiated with ultraviolet light, and the ozone generation rate can be improved. As a result, the ozone concentration (ozone content) of the ozone mist can be improved. Further, the air is ozonized in the ultraviolet lamp housing chamber to generate ozonized air, and the ozonized air is merged with ozone mist by the merging means. Not only the ozone in the ozone mist but also ozone of ozonized air can be added, and the ozone concentration can be further improved.

  Of course, if the merging means has a combined flow rate adjusting means such as an adjusting valve, the combined flow rate of the ozonized air can be adjusted, and the ozone concentration can be increased or decreased as necessary. It is also possible.

  In addition, since the water storage tank can be attached to and detached from the apparatus main body, water can be easily replenished and discarded. The storage tanks having different shapes and the storage tanks having different capacities can be attached and detached as necessary. Since the attachment / detachment sensor detects the attachment / detachment of the water storage tank, is it in a state where the water storage tank is attached to the device body and ozone mist can be generated, or whether the water tank is removed from the device body and ozone misses cannot be generated? Can be easily discriminated.

  The mist generating means may be provided in the apparatus main body or in the water storage tank. When the mist generating means is provided in the main body, there is no need to supply power or wiring for the mist generating means on the water tank side, but water supply that supplies water from the water tank to the mist generating means on the main body side A route is required. Further, mist generating means remains on the apparatus main body side even when the water storage tank is removed. Even if the water storage tank is replaced, the mist generating means on the apparatus main body side can be used in common.

  On the other hand, when a mist generating means is provided in the water storage tank, wiring for the mist generating means on the water tank side (contact terminal etc.) is required, but a water supply path to the apparatus main body side is unnecessary. Different types of mist generating means can be set for each water storage tank. Various mist generating means can be selected and used in the ozone mist generating device according to the capacity of the water storage tank and the user's preference.

  The water storage tank may be replaceable with spraying means having a bottle part having an ultraviolet lamp storage chamber and a spraying part for spraying ozonized water.

  Since the water storage tank is detachable, the spraying means can be used as a water storage tank. In this case, the water in the bottle is ozonized, and the ozonized water is atomized by the spray unit and used as ozone mist. No mist generating means is used in atomization. Further, the ozonized air is not joined by the joining means.

  The user can carry out the spraying of the ozone mist at a desired place after removing the spraying means from the apparatus main body after carrying out ozonization of the water in the bottle. Therefore, it is excellent in portability and portability, and ozone mist can be sprayed freely at a desired place without moving the apparatus main body.

  The apparatus main body may further include control means for controlling on / off of the ultraviolet lamp based on attachment / detachment of the water storage tank.

  The UV lamp can be turned off (turned off) by the control means when the water tank is removed from the main body of the apparatus, so that it is possible to prevent the UV lamp from being left on without the water tank. it can. The ultraviolet rays emitted from the ultraviolet lamp may be harmful to the human body depending on the wavelength and light quantity, but this configuration is dangerous because the ultraviolet lamp can be automatically turned off automatically when the water tank is removed. Contributes to prevention. It also contributes to power saving.

  The mist generating means may atomize the ozonized water by an ultrasonic method or a heating method.

  If an ultrasonic method is employed for the mist generating means, a fine mist of particles can be generated. In addition, it is safe at high temperatures and contributes to power saving. On the other hand, if a heating method is adopted for the mist generating means, since no ultrasonic vibrator is used, it is excellent in quietness, and can be made inexpensive with a simple structure. Moreover, since high temperature mist is generated with a heater, reproduction of bacteria etc. can be suppressed. Of course, either one may be used for the convenience of design or according to the user's preference, and the mist generating means may be replaced and used as appropriate. The mist generating means may be provided in the apparatus main body as described above, or may be provided in the water storage tank.

  Further problems or other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

  According to the present invention, by controlling the ozone concentration, the concentration can be increased as necessary, and humidification can be performed while enhancing the effects of sterilization and deodorization by ozone. Further, the water storage tank can be detachable, and the spraying means can be attached to the apparatus main body as required. In addition, it is possible to detect the attachment / detachment of the water storage tank and contribute to improvement of safety and power saving.

It is a flowchart which shows the control procedure by the control means of the ozonizer shown in FIG. It is an external appearance perspective view of the ozonizer which concerns on Embodiment 2 of this invention.

[Embodiment 1]
Hereinafter, the ozonizer (ozone mist generator) according to Embodiment 1 of the present invention will be described. FIG. 1 is an external perspective view of the ozonizer (ozone mist generator) S. FIG. FIG. 2 is a configuration diagram showing an outline of the internal configuration of the ozonizer S. As shown in FIG. In FIG. 2, it is partially shown in a sectional view.

  The ozonizer S has a device main body 2, a water storage tank 4, an ultraviolet lamp 6, a detachable sensor 8, a guide path (merging means) 10, and a mist generator (mist generating means) 12. The apparatus main body 2 is a main body part that contains main components as a base of the ozonizer S. The apparatus main body 2 includes an ultraviolet lamp 6, a detachable sensor 8, a mist generator 12, a water supply path 14, a switch 16, and a control means 18.

  The ultraviolet lamp 6 is a light emitting unit that emits ultraviolet light having a wavelength of 10 to 400 nm, for example. Ozone air and ozone water are generated by irradiating water and air with ultraviolet rays. The ultraviolet lamp 6 is, for example, a straight tube type extending vertically as shown in the figure, and emits ultraviolet rays in all directions. Air or water as an irradiation target is preferably present around the entire circumference of the ultraviolet lamp 6, and it is desirable from the viewpoint of improving ozonization efficiency to ensure a large irradiation area as much as possible. The ultraviolet lamp 6 is disposed so as to be positioned in the ultraviolet lamp storage chamber R of the water storage tank 4 in a state where the water storage tank 4 is mounted on the apparatus main body 2. The ultraviolet lamp 6 is positioned so that the water in the water storage tank 4 covers the periphery of the ultraviolet lamp 6, and the ultraviolet lamp 6 can efficiently ozonize the water. Further, the ultraviolet lamp 6 also ozonizes the air in the ultraviolet lamp storage chamber R. The ultraviolet lamp 6 is connected to the control means 18.

  The attachment / detachment sensor 8 is detection means for detecting attachment / detachment of the water storage tank 4 to / from the apparatus main body 2. The apparatus main body 2 has an attachment / detachment portion for attaching / detaching the water storage tank 4, and the water storage tank 4 can be attached / detached to / from the attachment / detachment portion. When the water storage tank 4 is attached to the apparatus main body 2, water from the water storage tank 4 is supplied to the apparatus main body 2, and when the water storage tank 4 is removed from the apparatus main body 2, water is supplied from the apparatus main body 2 side. Is stopped.

  The detachable sensor 8 outputs an on signal when the water storage tank 4 is attached to the apparatus main body 2 and outputs an off signal when the water storage tank 4 is detached. The attachment / detachment sensor 8 is, for example, a micro switch that detects attachment / detachment of the water storage tank 4 when the detection piece moves by contact with the water storage tank 4, and the detection light is blocked / transmitted by attachment / detachment of the water storage tank 4. A light emitting / receiving sensor or the like that detects attachment / detachment of the water storage tank 4 can be applied. The detachable sensor 8 is connected to the control means 18.

  The mist generator 12 is for atomizing the water supplied from the water storage tank 4. The water supplied from the water storage tank 4 is ozonized by the ultraviolet lamp 6 before reaching the mist generator 12. The mist generator 12 may be provided on the apparatus main body 2 side or may be provided on the water storage tank 4 side. When the mist generator 12 is provided on the water storage tank 4 side, it is necessary to supply power to the mist generator 12 on the water storage tank 4 side. Therefore, an electrical connection (connector) between the water storage tank 4 and the apparatus main body 2 is required. It is necessary to ensure connection and contact). In this case, a different mist generator 12 can be provided for each water storage tank 4.

  The mist generator 12 is, for example, an ultrasonic type that mists water by vibrating water with an ultrasonic vibrator, or mists by evaporating water by heating by a heating means such as a heater. A heating method or the like can be applied. Further, a vaporization type that vaporizes water by using heat in the air as heat of vaporization by contact with air can also be used as the mist generator (humidifying means) 12. In the first embodiment, the case where the mist generator 12 is of an ultrasonic type and is provided on the apparatus main body 2 side will be described as an example. Mist (ozone mist) generated by the mist generator 12 is discharged from the discharge port 2a of the apparatus body 2 into the atmosphere and diffused.

  The water supply path 14 is a path for guiding water supplied from the water storage tank 4 to the mist generator 12 when the water storage tank 4 is attached to the apparatus main body 2. When the mist generator 12 is provided on the water storage tank 4 side, the water supply path 14 is not necessary. However, in the first embodiment, the mist generator 12 is provided on the apparatus main body 2 side, so the water supply path 14 is provided. Is required.

  The water supply path 14 is formed in communication with, for example, a water supply hole 4 a formed in the water storage tank 4 and the mist generator 12. A shutter 4b is provided in the water supply hole 4a, and a projection 14a for opening and closing the shutter 4b is provided in the vicinity of the water supply path 14 on the apparatus main body 2 side. The water supply hole 4a of the water storage tank 4 is normally closed by a shutter 4b urged in the closing direction by an urging means such as a spring so that water does not leak from the water supply hole 4a.

  When the water storage tank 4 is attached to the apparatus main body 2, the projection 14 a opens the shutter 4 b against the urging force of the urging means, so that the inside of the water storage tank 4 is simultaneously installed with the water storage tank 4. Water flows into the water supply path 14. The water that flows into the water supply path 14 is guided to the mist generator 12.

  The switch 16 is for turning on / off the main power supply of the ozonizer S, and is provided in the apparatus main body 2. The switch 16 is connected to the control means 18, and power supply to the ultraviolet lamp 6, the detachable sensor 8, and the mist generator 12 can be started by turning on the switch 16.

  Of course, the switch 16 may be configured so that the ultraviolet lamp 6 and the mist generator 12 can be individually turned on and off. For example, it is convenient if only the power supply of the mist generator 12 can be individually turned off when the spraying means described later is attached to the apparatus main body 2 instead of the water storage tank 4. If comprised in this way, when the mist spraying means is attached instead of the water storage tank 4 and water is not supplied to the mist generator 12, the drive of the mist generator 12 can be stopped. In the first embodiment, a water supply sensor 14 b for detecting the presence or absence of water supply is provided in the water supply path 14 in the vicinity of the mist generator 12 while being connected to the control means 18. When the water supply sensor 14b detects the presence of water supply, a water supply presence signal is transmitted to the control means 18 to drive the mist generator 12, and when the water supply sensor 14b detects the absence of water supply, a water supply absence signal is transmitted to the control means 18. Then, the driving of the mist generator 12 is stopped.

  The control means 18 controls on / off of the ultraviolet lamp 6 based on the attachment / detachment of the water storage tank 4 to / from the apparatus main body 2. The control means 18 is configured electrically or electronically by, for example, a computer having a CPU, a relay type switch circuit, a sequence controller, or the like. The control means 18 is connected to the ultraviolet lamp 6, the attachment / detachment sensor 8, the mist generator 12, the water supply sensor 14 b, and the switch 16.

  The control means 18 controls the operation (on / off) of the ultraviolet lamp 6 and the mist generator 12 based on signals from the attachment / detachment sensor 8 and the water supply sensor 14b. Details of the control procedure will be described later.

  The water storage tank 4 is a tank member for storing water therein, and is configured to be detachable from the apparatus main body 2. FIG. 3 is a configuration diagram showing a schematic configuration of the water storage tank 4. The water storage tank 4 is made of, for example, resin, and includes an ultraviolet lamp storage chamber R, a water supply hole 4a, a shutter 4b, a guide path (merging means) 10, and an air hole 4c.

  When the water storage tank 4 is attached to the apparatus main body 2, the attachment is detected by the attachment / detachment sensor 8. The ultraviolet lamp housing chamber R is a concave chamber formed in a cylindrical shape on the bottom surface side so as to accommodate the ultraviolet lamp 6 on the apparatus main body 2 side, for example, so that water covers the periphery of the ultraviolet lamp 6. Be placed. When the water storage tank 4 is attached to the apparatus main body 2, the ultraviolet lamp 6 is disposed in the ultraviolet lamp storage chamber R, and the surrounding water is ozonized by the ultraviolet rays. Moreover, the air in the ultraviolet lamp storage chamber R is also ozonized by the ultraviolet rays.

  The guide path 10 is an air passage that connects the ultraviolet lamp housing chamber R and the air hole 4c. Ozonated air in the ultraviolet lamp housing chamber R is guided through the guide path 10 to the air hole 4c. In a state where the water storage tank 4 is attached to the apparatus main body 2, the air hole 4c and the introduction hole 2b on the apparatus main body 2 side face each other, and the air hole 4c passes through the introduction hole 2b to the apparatus main body 2 side. The ozonized air that has moved together joins ozone mist in the vicinity of the discharge port 2a and diffuses from the discharge port 2a into the atmosphere.

  In the first embodiment, the guide path 10 is formed as an air passage inside the water storage tank 4 so as to communicate the ultraviolet lamp housing chamber R and the air hole 4c. However, the guide path 10 only needs to join ozonized air with ozone mist. For example, the guide path 10 may be a connection tube connecting the ultraviolet lamp housing chamber R to the vicinity of the discharge port 2a. Further, at least a part of the guide path 10 may be formed on the apparatus main body 2 side, and ozonized air may be guided in the guide path 10 inside the apparatus main body 2 and merged with the ozone mist. The joining position with the ozone mist is not limited to the vicinity of the discharge port 2a, and the ozone mist and the ozonized air after the ozone water is atomized may be joined.

  The water supply hole 4a is closed by a shutter 4b urged in a closing direction by an urging means (not shown) in a state where the water storage tank 4 is detached from the apparatus main body 2, thereby preventing leakage of water. When the water storage tank 4 is attached to the apparatus main body 2, the protrusion 14 a pushes up the shutter 4 b to open the water supply hole 4 a, and the internal water is introduced into the water supply path 14.

  Next, the control procedure of the ozonizer S by the control means 18 will be described.

  FIG. 4 is a flowchart showing a control procedure of the ozonizer S by the control means 18. When the switch 16 is turned on (S1), the control means 18 starts supplying power to the attachment / detachment sensor 8 and monitors an on / off signal from the attachment / detachment sensor 8 (S2). At the same time, the control means 18 starts to supply power to the water supply sensor 14b, and monitors the water supply presence / absence signal from the water supply sensor 14b (S3).

  When the water storage tank 4 is attached to the apparatus main body 2 and the attachment / detachment sensor 8 is turned on (S4), the control means 18 turns on the ultraviolet lamp 6 (S5). On the other hand, when the water storage tank 4 is not attached to the apparatus main body 2 (or removed) and the attachment / detachment sensor 8 is turned off, the control means 18 turns off the ultraviolet lamp 6 (S6). Since the ultraviolet lamp 6 is turned off with the removal of the water storage tank 4, safety is high and power is saved.

  When the water storage tank 4 is attached to the apparatus main body 2 while water is stored in the water storage tank 4, the water in the water storage tank 4 is ozonized by the ultraviolet lamp 6. Further, the air in the ultraviolet lamp chamber R is also ozonized and guided into the guide path 10.

  When the water storage tank 4 is attached to the apparatus main body 2, the shutter 4b is opened. When water is stored in the water storage tank 4, ozonized water is supplied into the water supply path 14. When ozone water is supplied into the water supply path 14 and the water supply sensor 14b detects the presence of water supply (S7), the control means 18 drives the mist generator 12 (S8). As a result, ozone mist is generated and diffused from the outlet 2a of the apparatus body 2. At that time, the ozonized air that has been ozonized by the ultraviolet lamp 6 and guided by the guide path 10 merges with the ozone mist in the vicinity of the discharge port 2a to become a high concentration ozone mist, and the high concentration ozone mist is discharged to the discharge port. 2a is diffused.

  When the water in the water storage tank 4 decreases or the water storage tank 4 is removed from the apparatus main body 2 and there is no ozone water in the water supply path 14, the water supply sensor 14b detects no water supply (S7). In that case, the driving of the mist generator 12 is stopped (S9).

  In addition, a flow rate adjusting valve for controlling the passage of ozonized air, a shutter member for blocking the passage of ozonized air, and the like are installed in the guide path 10 and in the vicinity of either the air hole 4c or the introduction hole 2b. If the configuration is such that the combined flow rate to the ozone mist can be adjusted or cut off, not only the ozone concentration can be made high, but also the ozone concentration can be adjusted as necessary to make it low.

[Embodiment 2]
FIG. 5 is an external perspective view of the ozonizer S according to the second embodiment of the present invention. In this ozonizer S, the apparatus main body 2 portion is the same as that of the ozonizer S according to the first embodiment, but a mist spraying means 20 is mounted instead of the water storage tank 4.

  The ozonizer S is configured so that the water storage tank 4 can be attached and detached. And it is possible to remove the water storage tank 4 and attach the spraying means 20 to the apparatus main body 2 instead. The shape of the part corresponding to the attachment / detachment part of the apparatus main body 2 is made substantially common in the spraying means 20 and the water storage tank 4. That is, when the mist spraying means 20 is attached to the apparatus main body 2, the attachment / detachment sensor 8 detects the attachment of the mist spraying means 20.

  Of course, the attachment / detachment sensor 8 may detect only the attachment / detachment itself without distinguishing the attachment of the water storage tank 4 and the attachment of the mist spraying means 20, or the attachment of the water storage tank 4 and the attachment of the mist spraying means 20. It may be detected separately. For example, if the installation of the spraying means 20 can be detected separately from the installation of the water storage tank 4, the power supply to the mist generator 12 on the apparatus body 2 side is stopped or the water supply sensor is detected when the installation of the spraying means 20 is detected. The power supply to 14b can be stopped. Since the mist generator 12 and the water supply sensor 14b are not used when the spraying means 20 is mounted, unnecessary power supply can be stopped to contribute to power saving.

  Similar to the water storage tank 4, the spray lamp 20 has a UV lamp chamber R recessed in the bottle portion 20 a. Thereby, when the spraying means 20 is attached to the apparatus main body 2, the ultraviolet lamp 6 is accommodated in the ultraviolet lamp storage chamber R, and the water stored in the bottle portion 20a of the spraying means 20 is efficiently ozonized. be able to.

  The spraying means 20 has a spraying part 20b for spraying water in the bottle part 20a. Therefore, the ozone water can be atomized and sprayed by the spraying means 20 alone with the spraying means 20 removed from the apparatus main body 2. Even if the apparatus main body 2 is not moved, only the spraying means 20 can be moved to various places, and ozone mist can be generated there.

  The mist spraying means 20 is not provided with a merging means for merging the air in the ultraviolet lamp storage chamber R with the ozone mist. The spraying means 20 is excellent in portability, and is assumed to be used in a variety of places where it is carried and sprayed with ozone mist. Since it can be easily moved to a required place and the ozone mist can be sprayed in a spot at a pinpoint, there is no need to join ozonized air with the ozone mist.

  Further, when the mist spraying means 20 is attached to the apparatus main body 2, the attachment is detected by the attachment / detachment sensor 8, the ultraviolet lamp 6 is turned on, and the water in the bottle portion 20a is ozonized. Even in this case, since the water supply sensor 14b detects the absence of water supply, the mist generator 12 on the apparatus main body 2 side is in a drive stopped state. Of course, when the spraying means 20 is detached from the apparatus main body 2, the removal is detected by the attachment / detachment sensor 8, and the ultraviolet lamp 6 is turned off, so that safety is ensured.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these, A various deformation | transformation and change are possible within the range of the summary.
