Description

Deodorization device

Technical Field

The present invention relates to a deodorizing device for deodorizing by ozone.

Background

For example, patent document 1 describes an ozone sprayer for generating ozone by electrolyzing water stored in a container and spraying ozone water in which the generated ozone is contained in the water.

The ozone sprayer is a device for spraying ozone water onto objects such as toilets in toilets and sinks in kitchens to sterilize the objects, and the like, and therefore the amount of ozone water to be discharged needs to be sufficient to moisten the objects. Therefore, ozone water cannot be atomized into a small particle size, and is difficult to spread widely into a room, and thus it is difficult to deodorize a room such as a toilet or a kitchen using the above-described ozone atomizer.

Accordingly, it is considered to discharge ozone-containing air into the room instead of the above-described ozone water to perform deodorization of the room. The air containing ozone is different from ozone water, and is easily diffused widely indoors.

However, the concentration of ozone in the air emitted into the room where a person may exist is limited to a low concentration of, for example, 0.1ppm or less. Therefore, it is difficult to sufficiently deodorize the room using only ozone.

Problems to be solved by the invention

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a deodorizing device capable of satisfactorily deodorizing a room with ozone.

Solution for solving the problem

The main scheme of the invention relates to a deodorizing device. The deodorizing device of this embodiment is provided with: a first discharge unit for discharging ozone; a second discharge unit for discharging mist; a control unit configured to perform a deodorizing process in which ozone is emitted from the first emission unit and mist is emitted from the second emission unit; and a person detecting unit for detecting whether or not a person is present around the deodorizing means. Wherein the control section performs the deodorizing process based on the absence of a person around the deodorizing device.

For example, the person detection section may be configured to include a person sensor that outputs a detection signal corresponding to whether or not a person is present within a prescribed range from the deodorizing means.

According to the above configuration, the ozone emitted from the first emitting portion is mixed with the mist emitted from the second emitting portion in the indoor space, whereby OH radicals can be generated. Thus, the interior can be deodorized not only by the ozone from the first emission portion but also by the OH radicals, and the interior can be satisfactorily deodorized.

Further, since the deodorizing treatment is not performed when a person is present near the deodorizing device, the user is less likely to feel uncomfortable due to contact with the released ozone or mist.

In the deodorizing device according to the present aspect, the first discharging portion may be configured to include: an ozone generating unit that generates ozone from oxygen in the air; and an air blowing unit that blows the ozone generated by the ozone generating unit to the outside.

According to the above configuration, ozone can be emitted from the first emission portion by operating the ozone generating portion and the air blowing portion.

In the deodorizing device according to the present aspect, the second discharging portion may be configured to include: a container for storing water; an electrolysis unit configured to generate ozone from water in the container by electrolysis; and a mist generating unit that generates mist from water supplied from the container, the water containing ozone generated by the electrolysis unit.

According to the above configuration, the mist containing ozone can be discharged from the second discharge portion, and therefore, the deodorizing effect in the room can be further improved by the action of the ozone contained in the mist.

In the deodorizing device according to the present aspect, the second discharging unit may be configured to include a rechargeable battery as a supply source of electric power required for discharging the mist and be detachably provided to the first discharging unit, and the first discharging unit may be configured to include a power supply unit that supplies electric power for charging the rechargeable battery in a state where the second discharging unit is provided. In this case, the control section may perform the deodorizing process based on the second discharging section having been provided to the first discharging section.

According to the above configuration, the second discharge portion can be used in a state where the second discharge portion is separated from the first discharge portion. Further, by providing the second discharging portion in the first discharging portion and specifying the discharging position, ozone and mist can be discharged in a state where ozone and mist are easily mixed, and the deodorizing effect by ozone and OH radicals can be fully exhibited.

The structure of the ozone atomizer 2 will be described in detail with reference to fig. 1 to 4 (b).

The case 10 is constituted by a trunk portion 10a, a neck portion 10b, and a head portion 10 c. The upper portion of the trunk portion 10a is formed in a substantially bottomed cylindrical shape having a tapered shape that narrows toward the inside of the neck portion 10 b. A vertically elongated display window 11 is formed on the front side of the trunk portion 10 a. Further, a mode display unit 12 is formed in the trunk portion 10 a. Inside the trunk portion 10a, a display lamp 13 such as an LED is mounted at a position of the mode display portion 12. The display lamp 13 can be lighted in a plurality of colors, and is lighted in a color corresponding to an operation mode described later.

The neck portion 10b has a substantially cylindrical shape and extends in the up-down direction. The head portion 10c has a substantially square tubular shape and extends in the front-rear direction.

The container 210 has light transmittance and is formed in a shape corresponding to the case 10. The container 210 stores water such as pure water and tap water. The top surface of the container 210 has a lower height than the neck 10b of the housing 10. Thus, a space in which the components such as the pump 230, the switching unit 360, the operation unit 60, and the like are disposed is formed in the upper portion of the neck portion 10 b.

A protruding portion 211 having a shape corresponding to the display window 11 is formed on the front side of the container 210. The protruding portion 211 is exposed to the outside from the display window 11. The user can confirm the amount of water in the container 210 through the display window 11.

When the pump 230 is operated, water in the container 210 is sucked from the water suction port 241, and is sent to the electrolysis unit 220 through the water suction pipe 240, the pump 230, and the discharge pipe 250. When water passes through the electrolysis unit 220 in a state where the anode and the cathode are energized, the water is electrolyzed to generate ozone. The generated ozone is dissolved in water to generate ozone water.

The water feeding unit 30 includes: a water pipe 310, a rain pipe 320, a fog pipe 330, a rain valve 340, and a fog valve 350.

The water pipe 310 is connected to the outflow port 222 of the electrolysis unit 220.

The rain valve 340 and the fog valve 350 are electromagnetic valves, and constitute a switching unit 360 for switching which of the rain pipe 320 and the fog pipe 330 the ozone water flowing out from the generating unit 20 is to flow.

When the pump 230 is not in operation, the rain valve 340 and the fog valve 350 are in a closed state, and when the pump 230 is in operation, one valve is opened.

The ozone water discharged from the pump 230 flows through the water pipe 310. The ozone water supplied to the water supply pipe 310 is supplied to the rain discharge portion 40 through the rain pipe 320 when the rain valve 340 is opened, and is supplied to the mist discharge portion 50 through the mist pipe 330 when the mist valve 350 is opened.

The rain discharge portion 40 is disposed at the front end of the head portion 10c of the housing 10. An annular discharge port 41 having a tapered surface on the outer periphery thereof is provided on the front surface of the rain discharge portion 40. The discharge port 41 is exposed to the outside from the front end surface of the head portion 10 c. A circular payout plate 42 is provided at the payout opening 41. A plurality of holes 42a are formed in the payout plate 42 in a dispersed manner. A connection port 43 is provided at the rear of the rain water discharge portion 40, and the rain pipe 320 is connected to the connection port 43. A flow path 44 is formed from the connection port 43 to the discharge port 41 in the rain discharge portion 40. As shown by the one-dot chain line arrows in fig. 4 (a), the ozone water supplied to the rain discharge portion 40 through the rain pipe 320 is strongly discharged, i.e., sprayed, in a rain shape from the plurality of holes 42a of the discharge plate 42.

The mist discharge portion 50 is disposed at the rear end of the head portion 10c of the housing 10. The front surface of the mist emitting portion 50 is exposed to the outside from the rear end surface of the head portion 10 c. The mist discharge unit 50 includes a housing 510, an ultrasonic vibrator 520, and a water reservoir 530. The mist emitting portion 50 corresponds to a mist generating portion of the present invention.

A circular recess 511 is formed in the front surface of the housing 510, and a disk-shaped ultrasonic transducer 520 is attached to the recess 511. The ultrasonic transducer 520 includes a vibration surface 521 having a plurality of micropores and performing ultrasonic vibration.

The water storage tank 530 is disposed at an upper portion inside the housing 510. The volume of the reservoir 530 is much smaller than the volume of the container 210. An inflow pipe 531 is formed at the top surface of the reservoir 530. The inflow pipe 531 protrudes rearward from the rear surface of the housing 510. The mist pipe 330 is connected to the inflow pipe 531. Further, an overflow port 532 is formed at an upper portion of a rear surface of the reservoir tank 530. The overflow 532 protrudes rearward from the rear surface of the housing 510. The overflow pipe 540 is connected to the overflow 532.

The water storage tank 530 stores ozone water supplied to the mist discharge unit 50 through the mist pipe 330. When the ultrasonic vibrator 520 operates, the vibration surface 521 performs ultrasonic vibration. As a result, as shown in fig. 4 (b), the ozone water in contact with the vibration surface 521 at the outflow port 533 of the water storage tank 530 is atomized to form an ozone-containing mist. Mist is discharged from many micropores of the vibration surface 521 as a discharge port.

The rechargeable battery 710 and the charging circuit board 722 are disposed in the case 10 at the rear lower portion of the container 210.

A proximity switch 16 is disposed at the bottom of the housing 10. The proximity switch 16 is constituted by a reed switch or the like, and is turned on in response to the magnetic force of the magnet 140 provided to the charger 3 when the ozone atomizer 2 is provided to the mounting surface 102 of the charger 3.

The control unit 81 controls the lamp driving unit 84, the electrode energizing unit 85, the pump driving unit 86, the valve driving unit 87, the vibrator driving unit 88, the communication unit 89, and the like in accordance with programs stored in the storage unit 82 based on respective signals from the operation detecting unit 83, the proximity switch 16, and the like.

Referring again to fig. 1 and 2, the structure of the charger 3 will be described in detail.

The charger 3 includes a substantially cylindrical case 100 that is flat up and down. A slightly recessed recess 101 is formed in the top surface of the housing 100. The bottom surface of the recess 101 is a mounting surface 102 for mounting the ozone atomizer 2, and is parallel to the bottom surface of the housing 100. A discharge port 103 is formed in the peripheral surface of the housing 100 at the upper portion of the rear side. The discharge port 103 is constituted by a plurality of slit holes arranged in the circumferential direction. When the ozone atomizer 2 is mounted on the charger 3, the discharge opening 103 faces in the same direction as the vibration surface 521, which is the discharge opening of the mist discharge portion 50 of the ozone atomizer 2.

The housing 100 is provided with a power supply unit 110 and a magnet 140. The power supply unit 110 includes a power supply device 111 and a power transmission coil 112. A plug, not shown, is connected to the power supply device 111. When the plug is connected to the receptacle, power is supplied from a commercial power source to the power supply device 111. The power transmission coil 112 is formed by winding a wire in a spiral shape, and is disposed so as to be close to the mounting surface 102 at a position facing the power receiving coil 721 when the ozone atomizer 2 is mounted on the charger 3. The magnet 140 is disposed so as to be close to the mounting surface 102, and is disposed at a position facing the proximity switch 16 when the ozone atomizer 2 is mounted on the charger 3.

Further, an air duct 104 extending in the front-rear direction is provided in the housing 100. The front side of the air duct 104 is parallel to the bottom surface of the housing 100, and the rear side is inclined obliquely upward with respect to the bottom surface. In the case 100, a housing chamber 105 is formed so that the front side of the side face is recessed inward, and an inlet 104a of the duct 104 is connected to the housing chamber 105. The outlet 104b of the air duct 104 is connected to the discharge port 103. An ozone generator 120 is disposed in the duct 104, and a fan 130 is disposed in the housing 105. An ozone discharge unit 150 for discharging ozone is constituted by the ozone generator 120, the fan 130, and the air duct 104. The ozone generator 120 corresponds to an ozone generating section of the present invention, and the fan 130 corresponds to an air blowing section of the present invention.

Ozone generator 120 is a discharge type ozone generator, and generates electric discharge such as corona discharge and silent discharge between a pair of electrodes, and generates ozone from oxygen in air passing between the pair of electrodes.

The fan 130 is an axial flow fan, and takes in air from outside the housing 100 and sends the taken-in air to the ozone generator 120 in the duct 104. The fan 130 also causes ozone generated by the ozone generator 120 to be contained in air and to be discharged to the outside through the discharge port 103. The fan 130 may be a centrifugal fan.

In order to detect whether a person is present in the periphery of the ozone deodorizing device 1 within a predetermined range from the device, for example, a human sensor 160 is disposed at the rear of the housing 100.

A positioning structure is provided between the ozone atomizer 2 and the charger 3, the positioning structure being composed of a protrusion 106 formed in the housing 100 of the charger 3 and a recess 17 formed in the housing 10 of the ozone atomizer 2 and accommodating the protrusion 106, whereby the ozone atomizer 2 is not placed on the charger 3 in a state of being turned upside down.

Fig. 6 is a block diagram showing the structure of the charger 3.

In addition to the above configuration, the charger 3 further includes: a control unit 171, a storage unit 172, an inverter 173, a generator driving unit 174, a fan driving unit 175, and a communication unit 176.

The inverter 173 generates an ac voltage from the voltage supplied from the power supply device 111 in accordance with a control signal from the control unit 171, and applies the ac voltage to the power transmission coil 112. The inverter 173 constitutes the power supply unit 110 together with the power supply device 111 and the power transmission coil 112.

The generator driving section 174 drives the ozone generator 120 according to a control signal from the control section 171. The fan driving unit 175 drives the fan 130 according to a control signal from the control unit 171. The communication unit 176 communicates with the communication unit 89 of the ozone atomizer 2 by a short-range wireless communication system.

The human sensor 160 is a pyroelectric type or thermoelectromotive type infrared sensor, and outputs a detection signal that changes according to the magnitude of a temperature change caused by infrared rays emitted from a human being to the control unit 171. The control unit 171 compares the input detection signal with a predetermined threshold value to determine whether or not a person is present within a predetermined range from the ozone deodorizing device 1. For example, the detection signal has a waveform in which the peak voltage increases as the temperature difference of the ambient temperature, which is a temperature change when receiving infrared light emitted from a person, increases. The control unit 171 compares the peak voltage with a predetermined voltage that is a threshold value, and determines that a person is present when the peak voltage is higher than the predetermined voltage. In this way, the human sensor 160 and the control unit 171 detect whether or not a person is present within a predetermined range from the ozone deodorizing device 1. The human detection unit of the present invention is constituted by the human sensor 160 and the control unit 171.

The storage section 172 includes ROM, RAM, and the like. The storage unit 172 stores a program for causing the control unit 171 to execute predetermined processing. The storage unit 172 stores various parameters and various control flags for execution of the program.

The control unit 171 controls the inverter 173, the generator driving unit 174, the fan driving unit 175, the communication unit 176, and the like according to the program stored in the storage unit 172.

The ozone deodorizing device 1 performs an operation in a cleaning mode and an operation in a deodorizing mode. In the cleaning mode, when the charger 3 is disengaged, the ozone sprayer 2 releases ozone water in a rain shape from the rain release unit 40 by pressing the operation button 61, which is an operation of the operation unit 60. In addition, in the deodorizing mode, when the ozone atomizer 2 is installed in the charger 3 to charge, the ozone atomizer 2 periodically emits the mist containing ozone from the mist emitting portion 50 and, at the same time, the charger 3 emits ozone from the emission port 103 under the condition that no person exists in the vicinity of the ozone deodorizing device 1.

The process for the operation of the cleaning mode is performed by the control section 81 of the ozone atomizer 2, and the process for the operation of the deodorizing mode is performed cooperatively by the control section 81 of the ozone atomizer 2 and the control section 171 of the charger 3. The control unit 81 of the ozone atomizer 2 and the control unit 171 of the charger 3 constitute a control unit of the present invention.

Fig. 7 is a flowchart showing a control process of the ozone atomizer 2 by the control unit 81.

Referring to fig. 7, control unit 81 determines whether or not ozone atomizer 2 is provided in charger 3 based on/off of proximity switch 16 (S101).

When cleaning an object such as a toilet bowl or a kitchen sink, the user holds the ozone sprayer 2 in his/her hand and leaves the charger 3.

When the ozone atomizer 2 is not provided in the charger 3 (S101: NO), the control unit 81 executes the process of the cleaning mode (S102 to S104). That is, the control section 81 monitors whether or not the operation button 61 is pressed (S102). Then, when the operation button 61 is pressed (S102: yes), the control unit 81 opens the rain valve 340 (S103), and then causes the pump 230 and the electrolysis unit 220 to operate (S104). Thereby, the ozone water is transported from the generating section 20 to the rain discharging section 40, and is sprayed in a rain shape from the discharging outlet 41 of the rain discharging section 40. Although not shown in the flowchart of fig. 7, the control unit 81 causes the pump 230 to operate and then causes the electrolysis unit 220 to operate a little time after that. This makes it possible to apply electricity between the anode and the cathode in a state where the inside of the electrolytic portion 220 is surely filled with water, and to prevent a reduction in the life of these electrodes.

When the pump 230 is operated for a predetermined time (for example, 3 seconds), and the operation button 61 is still pressed when the predetermined time has elapsed, the pump 230 continues to operate until the pressing is released or a limited time (for example, 10 seconds) has elapsed. During operation of the pump 230, ozone water is discharged from the rain discharge portion 40. In this way, ozone water is released in a rain shape, and the amount of released ozone water increases. Therefore, the object is easily sufficiently wetted with ozone water. The rain valve 340 is closed when the pump 230 and the electrolysis unit 220 are stopped.

In the cleaning mode, the rain valve 340 is opened before the pump 230 is operated, so that the water pressure can be used to prevent the water pipe 310 from falling off the discharge port 232 of the pump 230.

In the case of deodorizing a room such as a toilet or a kitchen or in the case of charging the ozone atomizer 2, the user sets the ozone atomizer 2 in the charger 3.

When the ozone atomizer 2 is mounted on the charger 3 (S101: yes), the control unit 81 performs the cleaning mode processing (S105 to S111). Since the control unit 81 charges the rechargeable battery 710, power transmission is instructed to the control unit 171 of the charger 3 using short-range wireless communication (S105). Thereafter, the control section 81 waits for a mist generation instruction from the control section 171 of the charger 3 (S106).

When the control unit 81 receives the mist generation instruction (S106: yes), the deodorizing process is performed (S107 to S109). That is, the control unit 81 opens the mist valve 350 (S107), and then operates the pump 230 and the electrolysis unit 220 (S108). Thereby, the ozone water is transported from the generating unit 20 to the mist emitting unit 50 and stored in the water storage tank 530. Pump 230 continues to operate for a predetermined amount (e.g., about 1 cc) of ozone water stored in reservoir 530. The water level of the water reservoir 530 at this time is at least a water level that floods the vibration surface 521 of the ultrasonic vibrator 520. However, the ozone water does not remain fully stored in the water storage tank 530. The mist valve 350 is closed when the pump 230 and the electrolysis unit 220 stop operating.

Next, the control unit 81 operates the ultrasonic transducer 520 (S109). Thereby, the mist containing ozone is emitted from the vibration surface 521, which is the emission port of the mist emitting unit 50. The emitted mist floats in the air and diffuses into the room. Until the time when substantially all of the ozone water stored in the water storage tank 530 is discharged, the ultrasonic vibrator 520 continues to operate.

In the deodorizing treatment, the mist valve 350 is opened before the pump 230 is operated, and therefore, the water pressure can be used to prevent the water supply pipe 310 from falling off from the discharge port 232 of the pump 230.

When ozone water is excessively supplied to the water storage tank 530 for some reason and the water storage tank 530 is in a full state, the ozone water is discharged from the overflow port 532 and returned to the container 210 through the overflow pipe 540. This prevents ozone water from leaking into the case 10 by the water pressure, for example, the mist pipe 330 from falling off the inflow pipe 531 of the water storage tank 530. In addition, the returned ozone water can be reused.

When the ozone atomizer 2 is separated from the charger 3 while waiting for the fog generation instruction (S110: yes), the control unit 81 instructs the control unit 171 of the charger 3 to stop power transmission using the short-range wireless communication (S111). Then, the control unit 81 returns to the process of S101, and executes the process of the cleaning mode again until the ozone atomizer 2 is provided in the charger 3.

During the operation in the cleaning mode, the display lamp 13 is turned on in a color corresponding to the cleaning mode, and during the operation in the deodorizing mode, the display lamp 13 is turned on in a color corresponding to the deodorizing mode.

Fig. 8 is a flowchart showing the control process of the charger 3 performed by the control unit 171.

Referring to fig. 8, control unit 171 monitors a power transmission instruction from control unit 81 of ozone atomizer 2 (S201). When there is a power transmission instruction (yes in S201), the control unit 171 drives the inverter 173 (S202).

When the inverter 173 is operated, an alternating current flows through the power transmitting coil 112. By electromagnetic induction, an ac current flows to the power receiving coil 721 on the ozone atomizer 2 side, and an ac voltage is generated. The ac voltage is converted into a dc voltage by the charging circuit board 722 and supplied to the rechargeable battery 710. Thereby, the rechargeable battery 710 is charged.

Next, the control unit 171 monitors whether or not the operation timing has come (S203). When a predetermined time (for example, 10 minutes) has elapsed after the start of charging or after the start of the last ozone emission, the control unit 171 determines that the operation timing has come.

When the operation timing arrives (yes in S203), the control unit 171 determines whether or not a person is present within a predetermined range from the ozone deodorizing device 1 based on the detection signal from the person sensor 160 (S204). For example, when the ozone deodorizing device 1 is used in a relatively narrow room such as a toilet, if no person is present in the room, it is determined that no person is present.

If no person is present (S204: no), the control unit 171 performs deodorization processing (S205, S206). That is, the control unit 171 causes the ozone generator 120 and the fan 130 to operate (S205). Thereby, ozone is emitted from the emission port 103 of the charger 3. The released ozone diffuses into the room. Further, the control unit 171 instructs the control unit 81 of the ozone atomizer 2 to generate mist by using short-range wireless communication (S206).

As described above, at the same timing as the emission of ozone, based on the instruction of mist generation, mist containing ozone is emitted from the ozone sprayer 2 to the rear of the ozone deodorizing device 1 in the same manner as the ozone from the charger 3. Ozone emitted from the charger 3 is mixed with mist in the indoor space, and OH radicals are generated by the reaction of ozone with mist, i.e., water. The OH radicals have an oxidizing power similar to ozone, and thus the ozone from the charger 3 can deodorize the room by the OH radicals. The indoor space is also deodorized by ozone contained in the mist. In particular, when the ozone deodorizing device 1 is used in a toilet, ammonia odor generated in the toilet is not easily decomposed by ozone alone, but by adding mist, i.e., water, ozone and water come into contact with ammonia odor, thereby promoting the decomposition of ammonia odor by ozone, and thus ammonia odor is easily reduced.

In the charger 3, the rear side of the air duct 104 is inclined obliquely upward. Accordingly, ozone is emitted obliquely upward from the discharge port 103. Thus, the ozone emitted from the charger 3 is easily mixed with the mist emitted in the horizontal direction from the mist emitting portion 50 of the ozone atomizer 2, and OH radicals are easily generated.

The ozone generator 120 and the fan 130 are continuously operated for the same time as the mist is discharged from the ozone atomizer 2.

As described above, in the present embodiment, the timing of the emission and stop of ozone from the charger 3 is substantially the same as the timing of the emission and stop of mist from the ozone atomizer 2. However, the timing may not be substantially the same, as long as there is a period of overlap between the emission period of ozone from the charger 3 and the emission period of mist from the ozone sprayer 2. Alternatively, the ozone from the charger 3 may be emitted immediately before or immediately after the emission of the mist from the ozone atomizer 2, without overlapping, as long as the ozone and the mist can be mixed in the room to generate OH radicals.

When the presence of a person is detected while the ozone generator 120 and the fan 130 are in operation, at least the ozone generator 120 may be stopped.

During the period when the monitoring operation timing is coming, the control unit 171 also monitors the power transmission stop instruction from the control unit 81 of the ozone sprayer 2 (S207). When there is a power transmission stop instruction (yes in S207), control unit 171 stops inverter 173 (S208). Thereby, power transmission from the power transmission coil 112 is stopped. The control unit 171 returns to S201, and again monitors the power transmission instruction from the control unit 81 of the ozone atomizer 2.

Effect of the embodiments >

According to the present embodiment, a deodorizing process of emitting ozone from the charger 3 and emitting mist from the ozone atomizer 2 is performed. Thus, the ozone emitted from the charger 3 is mixed with the mist from the ozone sprayer 2 in the indoor space to generate OH radicals, and thus the indoor space is deodorized not only by the ozone from the charger 3 but also by the OH radicals. Thus, the indoor can be deodorized while the ozone concentration is kept low.

Further, since the deodorizing treatment is not performed when a person is present in the vicinity of the ozone deodorizing device 1, the user is less likely to feel uncomfortable due to contact with the released ozone or mist.

Further, according to the present embodiment, since the charger 3 includes the ozone generator 120 that generates ozone from oxygen in the air and the fan 130 that sends out ozone generated by the ozone generator 120 to the outside, ozone can be emitted from the charger 3 by operating the ozone generator 120 and the fan 130.

Further, according to the present embodiment, the ozone atomizer 2 employs a container 210 that stores water, an electrolysis unit 220 that generates ozone by electrolyzing water in the container 210, and a mist discharge unit 50 that generates mist from water containing ozone generated by the electrolysis unit 220 that is transported from the container 210. Accordingly, the mist containing ozone can be discharged from the ozone atomizer 2, and thus the indoor deodorizing effect is further improved by the action of the ozone contained in the mist.

Further, according to the present embodiment, the control section 81 of the ozone atomizer 2 and the control section 171 of the charger 3 are configured to perform the deodorizing process based on the ozone atomizer 2 having been provided to the charger 3. This can prevent the ozone and the mist from being emitted in a state where the ozone from the charger 3 and the mist from the ozone atomizer 2 are not easily mixed because the ozone atomizer 2 is in a state of being away from the charger 3, in other words, the ozone and the mist can be emitted in a state where the ozone and the mist are easily mixed by specifying the emission position, and the deodorizing effect by the ozone and the OH radicals can be fully exerted.

The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments and the like, and various modifications other than the above are possible.

For example, in the above embodiment, in order to detect whether or not a person is present within a predetermined range from the ozone deodorizing device 1, the human sensor 160 is used as a thermal type infrared sensor. However, a human sensor other than a thermal type infrared sensor and a human sensor other than an infrared sensor may be used.

In the above embodiment, the control unit 171 compares the detection signal from the human sensor 160 with the threshold value to detect the presence or absence of the human. However, it is also possible to detect the presence or absence of a person in the human sensor 160 and output a detection signal according to the detection result from the human sensor 160 to the control unit 171. In this case, the human detection unit of the present invention is constituted only by the human sensor 160.

In the above embodiment, the ozone deodorizing device 1 may be provided with an illuminance sensor as a human detection unit in addition to the human sensor 160. In this case, when the ozone deodorizing device 1 is used in a room that is dark without a window or the like and without being exposed to the light, the illuminance sensor is set to be operated. In the deodorization process of fig. 8, the control unit 171 detects whether or not the room is illuminated by the illuminance sensor, and when no person is considered to be present because the room is not illuminated and the presence of no person is detected by the human sensor 160, that is, when no person is detected in the vicinity of the ozone deodorizing device 1 by both the illuminance sensor and the human sensor 160, the ozone generator 120 and the fan 130 are operated, and ozone is emitted from the charger 3.

In the case where the ozone deodorizing device 1 is used only in a room where the area is dark without being illuminated, a configuration may be adopted in which the human sensor 160 is not provided and only the illuminance sensor is provided. In this case, the presence or absence of a person around the ozone deodorizing device 1 is detected only by the illuminance sensor.

In the above embodiment, the mist discharge unit 50 is configured to include the water storage tank 530 for storing the ozone water from the generation unit 20, and the ultrasonic vibrator 520 for atomizing the ozone water stored in the water storage tank 530 by ultrasonic vibration. However, the mist discharge unit 50 is not limited to the above-described configuration, and may be, for example, a nozzle having an aperture for discharging ozone water as mist.

In the above embodiment, the mist emitting portion 50 and the rain emitting portion 40 are arranged to face in opposite directions to each other, but may be arranged to face in the same direction.

The generating unit 20 may be configured other than the above-described embodiment. For example, the generating unit 20 may be configured to generate ozone water in the container 210. In this case, for example, the following structure can be adopted: ozone is generated from air by a discharge type ozone generator, and dissolved in water in the container 210 to generate ozone water, which is pumped by the pump 230 and sent to the water feeding unit 30.

In the above embodiment, the charger 3 is configured to discharge ozone obliquely upward from the discharge port 103 of the housing 100, and the discharge port 103 is provided at a position higher than the air duct 104 and the rear side of the air duct 104 is inclined. However, in order to achieve the above object, the outlet 103 may be formed to have the same height as the duct 104, and the duct 104 may be formed to be entirely parallel to the bottom surface of the housing 100, and a plurality of ventilation plates may be provided on the inner side of the outlet 103, that is, on the outlet 104b of the duct 104, so as to be arranged obliquely upward. The entire air duct 104 may be inclined so that the discharge port 103 side becomes higher. Also, the following structure may be adopted: the fan 130 is disposed in the duct 104 in an inclined state so as to convey air obliquely upward toward the discharge port 103.

In the above embodiment, the mist is emitted in the horizontal direction from the mist emitting portion 50 of the ozone atomizer 2 in the state where the ozone atomizer 2 is horizontal. However, the mist may be emitted obliquely downward from the ozone atomizer 2 by tilting the mist emitting portion 50 or the like. In this way, the emitted mist easily crosses the ozone emitted obliquely upward from the charger 3, and is easily mixed with the ozone, and OH radicals are easily generated.

In the above embodiment, the charging and deodorizing treatment is performed when the ozone atomizer 2 is provided in the charger 3. However, the ozone atomizer 2 may be provided with a power switch, and when the power switch is turned off, only the charging may be performed without performing the deodorizing treatment.

In the above embodiment, the charger 3 is configured to supply the electric power for charging to the ozone atomizer 2 in a noncontact manner. However, the charger 3 may be configured to supply electric power for charging to the ozone atomizer 2 by a contact method.

In the above embodiment, the ozone deodorizing device 1 is constituted by the ozone sprayer 2 and the charger 3. However, the structure of the ozone deodorizing device 1 is not limited to this structure. For example, the ozone deodorizing device 1 may be constituted only by the ozone sprayer 2, and the ozone emitting unit 150 originally provided in the charger 3 may be provided at the bottom of the case 10. In this case, the bottom of the housing 10 having the ozone emitting section 150 corresponds to the first emitting section of the present invention. In this case, the AC adapter may be connected to the ozone atomizer 2, and the charging power may be supplied from the AC adapter to the ozone atomizer 2.

In the above embodiment, in the deodorizing treatment, the mist containing ozone is emitted from the mist emitting portion 50 of the ozone atomizer 2. However, by performing a predetermined switching operation, the mist containing no ozone may be discharged from the mist discharge unit 50 during the deodorizing treatment. In this case, in S108 of fig. 7, the control unit 171 operates only the pump 230.

The ozone deodorizing device 1 may be configured by a discharge portion that discharges a mist containing no ozone and a discharge portion that discharges ozone, for example, a structure that discharges ozone may be provided at the bottom of a sprayer that discharges mist.

The embodiments of the present invention can be modified in various ways within the scope of the technical idea shown in the claims.
