Description

Deodorizing device

Technical field

The invention relates to a deodorizing device capable of deodorizing indoors.

Background technique

For example, Patent Document 1 describes an ozone sprayer that generates ozone by electrolyzing water stored in a container, and sprays ozone water containing the generated ozone in the water.

The above-mentioned ozone sprayer is a device that sprays ozone water to objects such as toilets in toilets and sinks in kitchens to disinfect and sterilize objects. Therefore, the amount of ozone water released must be sufficient to wet the objects. Therefore, the ozone water cannot be made into a mist with a small particle size, and it is difficult to diffuse widely into the room. Therefore, it is difficult to deodorize the room using the above-mentioned ozone spray.

Therefore, it is considered to deodorize the room by discharging air containing ozone into the room instead of the above-mentioned ozone water. Unlike ozone water, ozone-containing air easily diffuses into the room.

However, the concentration of ozone in the air released into the room where humans may be present is limited to a very low concentration, for example, 0.1 ppm or less. Therefore, it is difficult to sufficiently deodorize the room using only ozone.

Summary of the invention

The problem to be solved by the invention

The present invention was made in view of this problem, and its object is to provide a deodorizing device that can deodorize a room well using ozone.

Solutions used to solve the problem

The deodorizing device according to the main aspect of the present invention includes: a first emission unit that emits ozone; a second emission unit that emits mist; and a control unit that performs ozone emission from the first emission unit and emission from the second emission unit Deodorization of mist.

According to the above-mentioned structure, the ozone emitted from the first emission part is mixed with the mist emitted from the second emission part in the indoor space, whereby OH radicals can be generated. Thereby, not only the ozone from the first emission part but also the OH radicals can deodorize the room, and the room can be deodorized well.

In the deodorizing device of the present aspect, the first discharge part may be configured to include: a housing having a discharge port; an ozone generating part that generates ozone from air; and a blowing part that removes the ozone generated by the ozone generating part. It is sent to the outside through the discharge port.

According to the above configuration, ozone can be released from the first emitting unit by operating the ozone generating unit and the air blowing unit.

In the case of adopting the above structure, further, the discharge port may be provided on the side surface of the casing. In this case, the first emission part may be arranged so that the ozone generated by the ozone generation part is emitted obliquely upward from the emission port.

When such a structure is adopted, the ozone released from the first release portion can easily reach the upper part of the room.

In the deodorizing device of this aspect, the second discharge part may be configured to include: a container that stores water; and a mist generation part that generates mist from the water in the container.

According to the above configuration, the mist can be emitted from the second emitting portion by operating the mist generating portion.

In the case of adopting the above structure, further, the second discharge part may be configured to include an electrolysis part that generates ozone from water in the container by electrolysis. In this case, the mist generating unit generates mist from water containing ozone generated by the electrolysis unit.

When such a structure is adopted, the mist containing ozone can be discharged from the second discharge part. Therefore, the effect of the ozone contained in the mist further improves the deodorizing effect in the room.

In the deodorizing device of this aspect, the second discharge part may be configured to include a rechargeable battery as a supply source of power required to discharge mist, and the second discharge part may be detachably installed in the first discharge part. The first discharge part may be configured to include a power supply part that supplies power for charging the rechargeable battery in a state where the second discharge part is provided. In this case, the control unit may execute the deodorization process based on the fact that the second discharge unit is already provided in the first discharge unit.

According to the above configuration, the second discharge part can be used in a state where the second discharge part is separated from the first discharge part. Furthermore, it is possible to prevent the release of ozone and mist in a state where ozone and mist are difficult to mix due to the second emitting part being separated from the first emitting part. In other words, it is possible to release ozone in a state where ozone and mist are easily mixed by determining the release position. With mist, it can give full play to the deodorizing effect achieved by ozone and OH radicals.

1 to 4(b), the structure of the ozone sprayer 2 will be described in detail.

The housing 10 is composed of a trunk portion 10a, a neck portion 10b, and a head portion 10c. In the torso portion 10a, the upper portion thereof is formed in a substantially bottomed cylindrical shape having a tapered shape that becomes narrower toward the neck portion 10b. In the trunk portion 10a, a display window 11 elongated in the vertical direction is formed on the front side. In addition, a mode display portion 12 is formed in the trunk portion 10a. On the inner side of the torso portion 10a, a display lamp 13 such as an LED is mounted at the position of the mode display portion 12. As shown in FIG. The indicator lamp 13 can be lit in a variety of colors, and is lit in a color corresponding to the operation mode described later.

The neck portion 10b has a substantially cylindrical shape and extends in the vertical direction. The head 10c has a substantially square cylindrical shape and extends in the front-rear direction. The head 10c is open in the part corresponding to the rain release part 40 of a front-end surface, and the part corresponding to the mist release part 50 of a rear-end surface.

When the user holds the ozone sprayer 2 in hand, the user mainly grasps the neck 10b of the housing 10 from the rear side of the ozone sprayer 2.

The generating unit 20 includes: a container 210 for storing water; an electrolysis unit 220 for generating ozone from the water stored in the container 210 through electrolysis; and a pump 230 for sending ozone water to the rain release unit 40 and the mist release unit 50 through the water delivery unit 30 When transported, the ozone water is generated in the container 210 by dissolving ozone generated by the electrolysis unit 220 in water.

The container 210 is transparent or has light transmittance, and is formed in a shape corresponding to the housing 10. For the water stored in the container 210, pure water is used, for example. The height of the top surface of the container 210 is lower than the height of the neck 10b of the housing 10, and a space for arranging components such as the pump 230, the switching unit 360, and the operation unit 60 is formed on the upper portion of the neck 10b. In this way, the ozone sprayer 2 can be designed compactly by arranging components such as the pump 230 by using the inside of the neck 10b held by the user.

A protrusion 211 having a shape corresponding to the display window 11 is formed on the front side of the container 210. The protrusion 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. In addition, a water supply port 212 for discharging water into the container 210 is provided on the rear side of the container 210. The water supply port 212 slightly protrudes outward from the opening 14 provided in the housing 10. The cover 15 blocking the water supply port 212 is fitted into the opening 14.

The electrolysis unit 220 includes an anode, a cathode, and an ion exchange membrane, and is arranged at the bottom of the container 210. The pump 230 is arranged above the container 210 inside the neck 10b of the housing 10. The pump 230 is, for example, a diaphragm-driven small pump. A suction pipe 240 is connected to the suction port 231 of the pump 230. The suction port 241 at the front end of the suction pipe 240 is located at the bottom of the container 210.

When the anode and cathode of the electrolysis unit 220 are energized, the water flowing into the electrolysis unit 220 is electrolyzed to generate ozone. The generated ozone is released into the water in the container 210 and dissolved in the water. Thus, ozone water is generated. When the pump 230 operates, the ozone water in the container 210 is sucked from the suction port 241 of the suction pipe 240 and discharged from the discharge port 232 of the pump 230 through the suction pipe 240 and the pump 230.

The water delivery unit 30 includes a water delivery pipe 310, a rain pipe 320, a mist pipe 330, a rain valve 340, and a mist valve 350.

The water delivery pipe 310 is connected to the discharge port 232 of the pump 230. The rain pipe 320 and the mist pipe 330 branch from the water supply pipe 310, and are connected to the rain release part 40 and the mist release part 50, respectively. The rain pipe 320 and the mist pipe 330 are composed of two pipes, and a rain valve 340 and a mist valve 350 are respectively arranged between the two pipes. The rain valve 340 and the mist valve 350 are solenoid valves, and constitute a switching unit 360 that switches which of the rain pipe 320 and the mist pipe 330 to flow the ozone water flowing out of the generating unit 20 to. The switching unit 360 is arranged above the container 210 in the neck 10b of the housing 10 in the same manner as the pump 230.

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

The ozone water discharged from the pump 230 flows in the water delivery pipe 310. The ozone water delivered to the water delivery pipe 310 is delivered to the rain release unit 40 through the rain pipe 320 when the rain valve 340 is opened, and delivered to the mist release unit 50 through the mist pipe 330 in the case of the mist valve 350.

The rain release portion 40 is arranged at the front end of the head 10c of the housing 10. On the front surface of the rain discharge portion 40, a discharge port 41 having a tapered ring shape on the outer periphery is provided. The discharge port 41 is exposed to the outside from the front end face of the head 10c. A circular discharge plate 42 is attached to the discharge port 41. A plurality of holes 42a are formed dispersedly in the discharge plate 42. A connection port 43 is provided at the rear of the rain release portion 40, and the rain pipe 320 is connected to the connection port 43. In the inside of the rain discharge unit 40, a flow path 44 is formed from the connection port 43 to the discharge port 41. As shown by the one-dot chain arrow in (a) of FIG. 4, the ozone water conveyed by the rain pipe 320 to the rain discharge part 40 is strongly discharged|emitted in the form of rain from the several holes 42a of the discharge plate 42, and is sprayed.

The mist emission part 50 is arranged at the rear end of the head 10c of the housing 10. The front surface of the mist discharge part 50 is exposed to the outside from the rear end surface of the head 10c. The mist emission part 50 includes a housing 510, an ultrasonic vibrator 520, and a water storage tank 530. The mist emission part 50 corresponds to the mist generation part of this invention.

A circular recess 511 is formed on the front surface of the housing 510, and a disk-shaped ultrasonic vibrator 520 is attached to the recess 511. The ultrasonic vibrator 520 includes a vibrating surface 521 that has many micropores and performs ultrasonic vibration.

The water storage tank 530 is arranged at the upper part of the housing 510. The volume of the water storage tank 530 is much smaller than the volume of the container 210.

The mist tube 330 is connected to the inflow tube 531. In addition, an overflow port 532 is formed on the upper part of the rear surface of the water storage tank 530. The overflow port 532 protrudes rearward from the rear surface of the housing 510. The overflow pipe 540 is connected to the overflow 532. The front end of the overflow pipe 540 is placed in the container 210.

The water storage tank 530 has a portion extending obliquely downward toward the recess 511 of the housing 510, and an outflow port 533 is provided at the front end of the portion. The outflow port 533 is connected to the vibration surface 521 of the ultrasonic vibrator 520 in the recess 511.

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

The operating portion 60 is provided on the front side of the neck portion 10b of the housing 10. The operation unit 60 includes an operation button 61, and when the operation button 61 is pressed, an internal contact opening/closing switch is turned on.

The control unit 81 controls the lamp drive unit 84, the electrode energization unit 85, the pump drive unit 86, the valve drive unit 87, and the vibrator drive based on the respective signals from the operation detection unit 83, the proximity switch 16, etc., according to the program stored in the storage unit 82 Section 88, Communication Section 89, etc.

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

The charger 3 includes a substantially cylindrical housing 100 that is flat on the top and bottom. A slightly depressed recess 101 is formed on the top surface of the housing 100. The bottom surface of the recess 101 becomes a mounting surface 102 for mounting the ozone sprayer 2, and is parallel to the bottom surface of the housing 100. A discharge port 103 is formed in the upper part of the rear side on the side surface of the casing 100, that is, the peripheral surface. The discharge port 103 is composed of a plurality of slit holes arranged in the circumferential direction. When the ozone sprayer 2 is installed in the charger 3, the discharge port 103 has the same direction as the vibrating surface 521 of the discharge port of the mist discharge unit 50 of the ozone sprayer 2, that is, faces the rear direction of the ozone deodorizing device 1.

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 socket, power is supplied to the power supply device 111 from the commercial power source. The power transmission coil 112 is formed by winding a wire in a spiral shape, and is arranged at a position facing the power receiving coil 721 when the ozone sprayer 2 is installed in the charger 3 so as to be close to the mounting surface 102.

In addition, 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 casing 100, and the rear side is inclined obliquely upward with respect to the bottom surface. In the housing 100, a storage chamber 105 is formed such that the front side of the side surface is recessed inward, and the inlet 104 a of the air duct 104 is connected to the storage chamber 105. The outlet 104b of the air duct 104 is connected to the discharge outlet 103. An ozone generator 120 is arranged in the air duct 104, and a fan 130 is arranged in the storage chamber 105. The ozone generator 120 corresponds to the ozone generating unit of the present invention, and the fan 130 corresponds to the air blowing unit of the present invention.

The ozone generator 120 is a discharge type ozone generator, which generates discharges such as corona discharge and silent discharge between a pair of electrodes, and generates ozone from the air passing between the pair of electrodes.

The fan 130 is an axial fan that takes in air from the outside of the housing 100 and delivers the taken air to the ozone generator 120 in the air duct 104. In addition, the fan 130 contains the ozone generated by the ozone generator 120 in the air, and sends it to the outside through the discharge port 103. It should be noted that the fan 130 may also be a centrifugal fan.

A positioning structure is provided between the ozone sprayer 2 and the charger 3. The positioning structure is composed of a protrusion 106 formed on the housing 100 of the charger 3 and a recess 17 formed on the housing 10 of the ozone sprayer 2 and accommodating the protrusion 106. With this positioning structure, the ozone sprayer 2 will not be loaded into the charger 3 in a state where it is 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 151, a storage unit 152, an inverter 153, a generator drive unit 154, a fan drive unit 155, and a communication unit 156.

The inverter 153 generates an AC voltage from the voltage supplied from the power supply device 111 based on a control signal from the control unit 151 and applies it to the power transmission coil 112. The inverter 153 constitutes the power supply unit 110 together with the power supply device 111 and the power transmission coil 112.

The generator driving unit 154 drives the ozone generator 120 according to a control signal from the control unit 151. The fan driving unit 155 drives the fan 130 in accordance with a control signal from the control unit 151. The communication unit 156 communicates with the communication unit 89 of the ozone sprayer 2 by a short-range wireless communication method.

The storage unit 152 includes ROM, RAM, and the like. The storage unit 152 stores a program for causing the control unit 151 to execute predetermined processing. In addition, various parameters and various control flags used for program execution are stored in the storage unit 152.

The control unit 151 controls the inverter 153, the generator drive unit 154, the fan drive unit 155, the communication unit 156, and the like based on the program stored in the storage unit 152.

The ozone deodorizing device 1 performs the operation in the cleaning mode and the operation in the deodorization mode. In the cleaning mode, when the ozone sprayer 2 is separated from the charger 3, the ozone water is discharged from the rain discharge unit 40 in the form of rain based on the operation of the operation unit 60, that is, the depression of the operation button 61. In addition, in the deodorization mode, when the ozone sprayer 2 is installed in the charger 3 for charging, the ozone sprayer 2 periodically discharges mist containing ozone from the mist discharge part 50, and at the same time, the charger 3 discharges from the discharge port. 103 emits ozone.

The processing for the operation in the cleaning mode is executed by the control unit 81 of the ozone sprayer 2, and the processing for the operation in the deodorization mode, that is, the deodorization processing, is performed by the control unit 81 of the ozone sprayer 2 and the control unit 151 of the charger 3 carried out. The control unit 81 of the ozone sprayer 2 and the control unit 151 of the charger 3 constitute the control unit of the present invention.

FIG. 7 is a flowchart showing the control process of the ozone sprayer 2 performed by the control unit 81.

7, the control unit 81 determines whether the ozone sprayer 2 is installed in the charger 3 based on the on and off of the proximity switch 16 (S101).

When cleaning objects such as a toilet in a bathroom or a sink in a kitchen, the user takes the ozone sprayer 2 in his hand and leaves the charger 3.

When the ozone sprayer 2 is not installed in the charger 3 (S101: No), the control unit 81 executes the processing of the cleaning mode (S102 to S104). That is, the control unit 81 monitors whether 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 operates the pump 230 (S104). Thereby, the ozone water in the container 210 is sent to the rain release part 40, and is sprayed like rain from the discharge port 41 of the rain release part 40. As shown in FIG. It should be noted that although not shown in the flowchart of FIG. 7, the control unit 81 periodically operates the electrolysis unit 220 to maintain the ozone concentration of the ozone water in the container 210 within a predetermined range.

The pump 230 operates for a predetermined time (for example, 1 second). If the operation button 61 is still pressed after the predetermined time has passed, the pump 230 continues to operate until the pressing is released or the limited time (for example, 10 seconds) has passed. While the pump 230 is operating, ozone water is discharged from the rain discharge unit 40. In this way, ozone water is released in the form of rain, so the release amount increases. Therefore, the object is easily wetted by ozone water. The rain valve 340 is locked when the pump 230 is stopped.

It should be noted that in the cleaning mode processing, the rain valve 340 is opened before the pump 230 is operated. Therefore, the water pressure can be used to prevent the water delivery pipe 310 from falling off the discharge port 232 of the pump 230.

When deodorizing indoors such as toilets and kitchens, or when charging the ozone sprayer 2, the user installs the ozone sprayer 2 on the charger 3.

When the ozone sprayer 2 is installed in the charger 3 (S101: Yes), the control unit 81 is to charge the rechargeable battery 710, and therefore instructs the control unit 151 of the charger 3 to transmit power using short-range wireless communication (S105). After that, the control unit 81 executes deodorization processing (S106 to S109). That is, the control unit 81 monitors whether the operation timing has come (S106). When a predetermined time (for example, 10 minutes) has elapsed since the start of charging or since the mist discharging section 50 started discharging ozone water last time, the control section 81 determines that the operation timing has come.

When the operation timing comes (S106: Yes), the control unit 81 opens the mist valve 350 (S107), and then operates the pump 230 (S108). As a result, the ozone water in the container 210 is sent to the mist release unit 50 and stored in the water storage tank 530. The pump 230 continues to work according to the time required for the ozone water to be stored in the storage tank 530 in a prescribed amount (for example, about 1 cc). The water level of the water storage tank 530 at this time becomes the water level at least submerging the vibration surface 521 of the ultrasonic vibrator 520. However, the ozone water does not become a state in which the water storage tank 530 is full. The mist valve 350 is locked when the pump 230 stops working.

Next, the control unit 81 operates the ultrasonic vibrator 520 (S109). Thereby, the mist containing ozone is emitted from the vibrating surface 521 which is the emission port of the mist emission part 50. As shown in FIG. The emitted mist floats in the air and spreads into the room. The ultrasonic vibrator 520 continues to operate until the time when almost all the ozone water stored in the water storage tank 530 is discharged.

It should be noted that in the deodorization process, the mist valve 350 is opened before the pump 230 is operated. Therefore, the water pressure can be used to prevent the water delivery pipe 310 from falling off the discharge port 232 of the pump 230.

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

When the ozone sprayer 2 is separated from the charger 3 during the arrival of the monitoring operation timing (S110: Yes), the control unit 81 instructs the control unit 151 of the charger 3 to stop power transmission using short-range wireless communication (S111). Then, the control unit 81 returns to the processing of S101 and executes the processing of the cleaning mode again until the ozone sprayer 2 is installed in the charger 3.

It should be noted that during the operation of the cleaning mode, the indicator lamp 13 lights up in a color corresponding to the cleaning mode, and during the operation of the deodorization mode, the indicator lamp 13 lights up in a color corresponding to the deodorization mode. .

FIG. 8 is a flowchart showing the control process of the charger 3 performed by the control unit 151.

Referring to Fig. 8, the control unit 151 monitors the power transmission instruction from the control unit 81 of the ozone sprayer 2 (S201). Then, when there is a power transmission instruction (S201: Yes), the control unit 151 drives the inverter 153 (S202).

When the inverter 153 is operating, an alternating current flows through the power transmission coil 112. By electromagnetic induction, an alternating current flows to the power receiving coil 721 on the side of the ozone sprayer 2 to generate an alternating voltage. The AC voltage is converted into a DC voltage through the charging circuit board 722 and supplied to the rechargeable battery 710. Thus, the rechargeable battery 710 is charged.

Next, the control unit 151 executes deodorization processing (S203, S204). That is, the control unit 151 monitors whether the operation timing has come (S203). When the same predetermined time (for example, 10 minutes) as the mist emission from the ozone sprayer 2 has elapsed after the start of charging or the last ozone emission started, the control unit 81 determines that the operation timing has come. It should be noted that, when the control unit 81 of the ozone sprayer 2 determines in S106 of FIG. 7 that the operation timing has come, a predetermined notification may be given to the control unit 151, and by receiving the notification, the control unit 151 determines that the operation timing is Has arrived.

When the operation timing comes (S203: Yes), the control unit 151 operates the ozone generator 120 and the fan 130 (S204). As a result, ozone is discharged from the discharge port 103 of the charger 3. The released ozone diffuses into the room.

At the same timing, mist containing ozone is emitted from the ozone sprayer 2 in the same direction as the ozone from the charger 3, that is, behind the ozone deodorizing device 1. The ozone emitted from the charger 3 is mixed with the mist in the indoor space to generate OH radicals. OH radicals have the same oxidizing power as ozone. Therefore, not only the ozone from the charger 3 but also the OH radicals are used to deodorize the room. In addition, the ozone contained in the mist deodorizes the room. In the charger 3, the rear side of the air duct 104 is inclined diagonally upward. Therefore, ozone is emitted obliquely upward from the emission port 103. Thereby, the ozone emitted from the charger 3 is easily mixed with the mist emitted in the horizontal direction from the mist emission part 50 of the ozone sprayer 2, and OH radicals are easily generated.

The ozone generator 120 and the fan 130 continue to operate for the same time as the time when the mist is discharged from the ozone sprayer 2.

In this way, in the present embodiment, the timing of the emission and stopping of ozone from the charger 3 is the same as the timing of the emission and stopping of the mist from the ozone sprayer 2. However, the above timing may not be the same as long as there is an overlap period between the ozone emission period from the charger 3 and the mist emission period from the ozone sprayer 2. Alternatively, as long as the ozone and mist can be mixed indoors to generate OH radicals, the release of ozone from the charger 3 may be performed immediately before or after the release of the mist from the ozone sprayer 2 without overlapping period.

During the arrival of the monitoring operation timing, the control unit 151 also monitors the power transmission stop instruction from the control unit 81 of the ozone sprayer 2 (S205). Then, when there is a power transmission stop instruction (S205: Yes), the control unit 151 stops the inverter 153 (S206). Thus, the power transmission from the power transmission coil 112 is stopped. The control unit 151 returns to S201 and monitors the power transmission instruction from the control unit 81 of the ozone sprayer 2 again.

According to the present embodiment, the deodorizing process in which ozone is discharged from the charger 3 and mist is discharged from the ozone sprayer 2 is performed. As a result, 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. Therefore, not only the ozone from the charger 3 but also the OH radicals deodorize the room. As a result, the room can be deodorized well.

In addition, since the charger 3 includes a housing 100 having a discharge port 103, an ozone generator 120 that generates ozone from the air, and a fan 130 that sends the ozone generated by the ozone generator 120 to the outside through the discharge port 103, so Ozone can be discharged from the charger 3 by operating the ozone generator 120 and the fan 130.

In addition, the charger 3 adopts a structure in which the ozone generated by the ozone generator 120 is discharged obliquely upward from the discharge port 103 provided on the side surface of the housing 100. As a result, the released ozone easily reaches the upper part of the room. In addition, the ozone emitted from the charger 3 easily crosses the mist emitted from the ozone sprayer 2 located above the charger 3, so ozone and mist are easily mixed, and OH radicals are easily generated. As a result, the deodorizing effect in the room is improved.

Furthermore, since the ozone sprayer 2 has a structure including a container 210 storing water and a mist discharge unit 50 that generates mist from the water in the container 210 and emits the mist, the mist can be discharged from the ozone sprayer 2 by operating the mist discharge unit 50 .

In addition, the ozone sprayer 2 further includes an electrolysis unit 220 that generates ozone from water in the container 210 by electrolysis, and the mist emission unit 50 adopts a structure that generates mist from water containing ozone generated by the electrolysis unit 220. Thereby, the mist containing ozone can be discharged from the ozone sprayer 2, and therefore, the deodorizing effect in the room is further improved by the action of the ozone contained in the mist.

Furthermore, the control unit 81 of the ozone sprayer 2 and the control unit 151 of the charger 3 are configured to perform deodorization processing based on the fact that the ozone sprayer 2 has been installed in the charger 3. Thereby, it is possible to prevent ozone and mist from being released in a state where the ozone from the charger 3 and the mist from the ozone sprayer 2 are difficult to mix due to the ozone sprayer 2 being in a state away from the charger 3. In other words, it is possible to determine the release position. Ozone and mist are released in a state where ozone and mist are easily mixed, and the deodorizing effect realized by ozone and OH radicals can be fully exerted.

As mentioned above, the embodiment of the present invention has been described, but the present invention is not limited by the above-mentioned embodiment and the like at all. In addition, the embodiment of the present invention may be variously modified in addition to the above.

For example, in the above-described embodiment, pure water is used as the water stored in the container 210. However, tap water may be stored in the container 210. In this case, compared to pure water, tap water is more likely to contain impurities. Therefore, in order to prevent the electrode of the electrolysis section 220 from being easily aged due to the adhesion of impurities, the following structure can also be adopted: The port 212 is provided with a filter made of a filter material such as a hollow fiber membrane for filtering water such as tap water to remove impurities or a filter capable of removing other impurities.

In addition, in the above-described embodiment, the mist emission unit 50 includes a water storage tank 530 that stores ozone water from the generation unit 20 and an ultrasonic vibrator 520 that atomizes the ozone water stored in the water storage tank 530 by ultrasonic vibration. However, the mist emission part 50 is not limited to the above-mentioned structure, for example, it may be a structure of the nozzle which has an aperture which emits ozone water in a mist form.

Furthermore, in the above-mentioned embodiment, the mist emission part 50 and the rain emission part 40 are arrange|positioned so that it may face in the opposite direction, but they may be arrange|positioned so that it may face in the same direction.

Furthermore, the generating unit 20 may adopt a structure other than the structure of the above-mentioned embodiment. For example, the generating unit 20 may also adopt a structure in which ozone is generated from the air by a discharge-type ozone generator, the ozone is dissolved in the water in the container 210 to generate ozone water, and the ozone water is sucked by the pump 230 and sent to the water部30 Delivery. In addition, instead of generating ozone water in the container 210 as in the above-mentioned embodiment, the generation unit 20 may provide an electrolysis unit 220 upstream or downstream of the pump 230, and the water in the container 210 is sent to the water delivery unit 30 through the pump 230. At this time, the delivered amount of water is electrolyzed by the electrolysis unit 220 to generate ozone, and the ozone is dissolved in the water to generate ozone water.

Furthermore, in the above-mentioned embodiment, as a structure for discharging ozone from the discharge port 103 of the casing 100 obliquely upward, the discharge port 103 is provided at a higher position than the air duct 104 and the rear side of the air duct 104 is inclined. The way to form the charger 3. However, for the above purpose, the discharge port 103 may be set to be the same height as the air duct 104, and the air duct 104 as a whole is parallel to the bottom surface of the housing 100, and the outlet 104b of the air duct 104 is located inside the discharge port 103, up and down. A plurality of ventilation panels facing diagonally upward are arranged side by side. In addition, the entire air duct 104 may be inclined so that the discharge port 103 side becomes higher. Furthermore, it is also possible to adopt a structure in which the fan 130 is arranged in an inclined state in the air duct 104 to blow air toward the discharge port 103 obliquely upward.

Furthermore, in the above-described embodiment, in the state where the ozone sprayer 2 is horizontal, the mist is discharged in the horizontal direction from the mist discharge part 50 of the ozone sprayer 2. However, the mist may be emitted obliquely downward from the ozone sprayer 2 by inclining the mist emitting portion 50 or the like. In this way, the emitted mist easily intersects with the ozone emitted diagonally upward from the charger 3, and the ozone is easily mixed, and OH radicals are easily generated.

Furthermore, in the above-described embodiment, charging and deodorizing treatment are performed when the ozone sprayer 2 is installed in the charger 3. However, it is also possible that a power switch is provided in the ozone sprayer 2, and only charging is performed when the power switch is turned off, and no deodorizing treatment is performed. In this case, when the power switch is turned off, the regular electrolysis by the electrolysis unit 220 is not performed.

In addition, in the above-mentioned embodiment, a structure is adopted in which the electric power for charging is supplied from the charger 3 to the ozone sprayer 2 by a non-contact method. However, it is also possible to adopt a configuration in which electric power for charging is supplied from the charger 3 to the ozone sprayer 2 by a contact method.

Furthermore, in the above-mentioned 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 generator 120 and the fan 130 provided in the charger 3 may be provided at the bottom of the casing 10 to emit ozone. In this case, the bottom of the casing 10 having a structure for emitting ozone corresponds to the first emitting portion of the present invention. Furthermore, in this case, it is preferable to adopt a structure in which an AC adapter is connected to the ozone sprayer 2 and the ozone sprayer 2 is supplied with electric power for charging from the AC adapter.

In addition, the ozone deodorizing device 1 may have a structure composed of a discharge part which discharges ozone-free mist and a discharge part which discharges ozone. For example, a structure which discharges ozone is provided at the bottom of a mist discharger.

In addition, the embodiments of the present invention can be appropriately modified in various ways within the scope of the technical idea shown in the technical solution.
