Description

Deodorizer

technical field

The invention relates to a deodorizing device utilizing ozone for deodorizing.

Background technique

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

The above-mentioned ozone sprayer 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 needs to be sufficient to wet the objects. Therefore, since ozone water cannot be made into a mist with a small particle size, and it is difficult to diffuse widely in the room, it is difficult to deodorize the room using the above-mentioned ozone sprayer.

Therefore, it is considered to deodorize the room by releasing the air containing ozone into the room instead of the above-mentioned ozone water. Unlike ozone water, ozone-containing air tends to diffuse widely indoors.

However, when gaseous ozone is released from the deodorizer for deodorization, the odor of ozone that can be felt by a person is easily diffused to the surroundings due to the release of ozone, and when a person comes to the deodorizer When it is nearby, for example, in a narrow room such as a toilet, when a person enters the room, there is a risk that the person will feel uncomfortable due to the smell of ozone.

SUMMARY OF THE INVENTION

The problem to be solved by the invention

The present invention has been made in view of this problem, and an object thereof is to provide a deodorizing apparatus which is less likely to feel uncomfortable for a person and which can deodorize well by using ozone.

solution to the problem

The main scheme of the present invention relates to a deodorizing device. The deodorizing device of this aspect includes: a first discharge unit that discharges ozone; a second discharge unit that discharges mist; a control unit that controls the first discharge unit and the second discharge unit; and a person detection unit that detects a distance Whether anyone exists within the specified range of the deodorizing device. When the presence of a person is not detected by the person detection unit, the control unit causes the first emission unit to emit ozone, and when the presence of a person is detected by the person detection unit while ozone is being emitted, the control unit causes the first emission unit to emit ozone. The control part stops the ozone emission from the first discharge part and discharges the mist from the second discharge part.

According to the above configuration, when someone comes to the vicinity of the deodorizer while the first discharge part is discharging ozone, the ozone remaining in the vicinity is decomposed by the mist discharged from the second discharge part, and its concentration decreases rapidly, and the ozone odor rapidly weakens. Thereby, it can make it difficult for a person to feel uncomfortable.

The deodorizing device of the present aspect further includes a temperature detecting unit for detecting the ambient temperature of the deodorizing device, and the human detecting unit may include an output corresponding to a magnitude of a temperature change caused by infrared rays emitted by a human being. A human-sensing sensor for a detection signal that changes in the ground, and a determination unit that determines whether or not a person is present by comparing the detection signal with a predetermined threshold value. In this case, the control section may be configured to adjust the threshold value so as to determine the presence of a person based on the temperature change, which is larger as the temperature detected by the temperature detection section is lower.

According to the above-described configuration, the fluctuation of the detection range of the presence of a person due to changes in ambient temperature can be suppressed, so that it is less likely that the emission of ozone does not stop regardless of whether there is a person in the vicinity of the deodorizing device due to room temperature, etc. There is no one that does not emit ozone.

The deodorizing device of the present aspect further includes a temperature detection unit that detects the ambient temperature of the deodorizing device, and the first discharge unit may be configured to include an ozone generating unit that generates ozone from oxygen in the air. In this case, the control unit may adopt a configuration in which the amount of mist per unit time released by the second release unit increases as the temperature detected by the temperature detection unit decreases.

According to the above-mentioned configuration, the lower the ambient temperature of the deodorizer, the higher the concentration of ozone released from the first discharge part, and the greater the amount of mist discharged per unit time from the second discharge part, so that the fog can be suppressed. No matter what the ambient temperature is, the ozone concentration can be quickly reduced to an appropriate level, and the ozone odor can be quickly reduced to an appropriate state.

In the deodorizing apparatus of the present aspect, the first discharge unit may include an ozone generation unit that generates ozone from oxygen in the air, and an ozone generation unit that sends out the ozone generated by the ozone generation unit to the outside of the first discharge unit. The structure of the air supply unit. In this case, when the presence of a person is not detected by the person detection unit, the control unit may operate the ozone generating unit and the blower unit, and when ozone is being emitted, the control unit may When the person detection unit detects the presence of a person, the control unit stops the operation of the ozone generating unit and causes the blower unit to operate.

According to the above-mentioned configuration, when someone comes to the vicinity of the deodorizer while ozone is being emitted, the ozone generation unit is stopped to stop ozone emission, while the blower unit operates to release air. Thereby, the mist discharged from the second discharge part is diffused by the discharged air, and the periphery of the deodorizer is suppressed from being wetted by the mist.

When the proximity switch 16 detects that the ozone sprayer 2 is installed in the charger 3 , the control unit 81 of the ozone sprayer 2 instructs the control unit 181 of the charger 3 to start charging using short-range wireless communication. The control unit 181 operates the inverter 183 so that the alternating current flows through the power transmission coil 112 . By electromagnetic induction, an alternating current flows to the power receiving coil 721 on the ozone sprayer 2 side to generate an alternating voltage. 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.

In the ozone deodorizing apparatus 1, when the ozone sprayer 2 is installed in the charger 3, the operation of the ozone gas mode is performed, and the air containing ozone is discharged from the discharge port 103 of the charger 3. The ozone concentration in the discharged air is higher than the ozone concentration in the mist discharged from the ozone sprayer 2 in the ozone mist mode. In addition, the decomposition of ozone does not occur due to water in the mist. Therefore, the effect of deodorizing indoors is high.

On the other hand, the ozone gas mode is more prone to ozone odor than the ozone fog mode. Many users are easily uncomfortable with the smell of ozone. Therefore, in the ozone gas mode, when no one exists in the vicinity of the ozone deodorizing device 1, the discharge of ozone is performed from the charger 3. Also, when someone comes to the vicinity of the ozone deodorizing device 1 while ozone is being emitted, the ozone emission is stopped and mist is emitted from the ozone sprayer 2 so that the ozone is rapidly decomposed to reduce the ozone odor.

The processing for the operation of the ozone gas mode is executed by the control unit 81 of the ozone sprayer 2 and the control unit 181 of the charger 3 in cooperation. The control unit of the present invention is constituted by the control unit 81 of the ozone sprayer 2 and the control unit 181 of the charger 3 .

FIG. 7 is a flowchart showing the control process of the ozone atomizer 2 by the control unit 81 in the ozone gas mode. FIG. 8 is a flowchart showing control processing of the charger 3 by the control unit 181 in the ozone gas mode.

7, in the ozone sprayer 2, the control part 81 determines whether the ozone sprayer 2 is installed in the charger 3 based on the ON/OFF of the proximity switch 16 (S101).

The user sets the ozone sprayer 2 on the charger 3 when the ozone sprayer 2 is used.

When the ozone sprayer 2 is installed in the charger 3 ( S101 : YES), the control unit 81 transmits a notification of the setting to the control unit 181 of the charger 3 using short-range wireless communication ( S102 ). Then, the control part 81 waits for the instruction|indication of mist generation from the control part 181 (S103), monitoring the leaving|separation of the ozone sprayer 2 from the charger 3 (S107).

8 , in the charger 3, the control unit 181 determines whether or not the ozone sprayer 2 is installed in the charger 3 (S201). When the notification of the installation of the control unit 81 of the ozone sprayer 2 is received, the control unit 81 determines that the ozone sprayer 2 is installed in the charger 3 .

When the ozone sprayer 2 is installed in the charger 3 ( S201 : YES), the control unit 181 first sets a threshold value to be compared with the detection signal from the human-sensing sensor 160 based on the ambient temperature of the ozone deodorizing device 1 , and performs Setting of the output of the ultrasonic vibrator 520 of the mist discharge part 50 of the ozone sprayer 2 (S202 to S207).

That is, the control part 181 detects the surrounding temperature with the temperature sensor 170 (S202), and determines whether the surrounding temperature is lower than a predetermined temperature (S203).

In the human detection sensor 160, when the distance from the sensor to the person is the same, the lower the ambient temperature, the larger the temperature change due to the infrared rays emitted by the person, and the higher the peak voltage of the detection signal. Therefore, when the ambient temperature is lower than the predetermined temperature ( S203 : YES), the control unit 181 sets the threshold value to be compared with the detection signal from the human-presence sensor 160 to a relatively high value so as to be determined based on a relatively large temperature change as Someone exists (S204). On the other hand, when the ambient temperature is equal to or higher than the predetermined temperature ( S203 : NO), the control unit 181 sets the threshold to a relatively low value so as to determine that a person is present with a relatively small temperature change ( S206 ). By performing such threshold value adjustment, fluctuations in the detection range of the presence of a person using the human presence sensor 160 due to changes in ambient temperature are suppressed.

In addition, in the ozone emission part 150, when the same voltage is applied to the ozone generator 120, the lower the ambient temperature is, the more ozone is generated by the ozone generator 120, and therefore the more ozone is emitted, and the ozone concentration is increased. higher. If the ozone concentration is not high, the amount of water required to decompose ozone and reduce the ozone concentration to a predetermined level increases. Therefore, when the ambient temperature is lower than the predetermined temperature ( S203 : YES), the control unit 181 sets the output of the ultrasonic transducer 520 to a relatively high value so that the amount of mist released per unit time from the mist release unit 50 is increased. relatively more (S205). On the other hand, when the ambient temperature is equal to or higher than the predetermined temperature ( S203 : NO), the control unit 181 sets the output of the ultrasonic vibrator 520 to a relatively low value so that the mist per unit time from the mist discharge unit 50 is reduced in volume. The release amount is relatively small (S207). In order to change the output of the ultrasonic vibrator 520, for example, the amplitude and period of ultrasonic vibration are changed. By adjusting the amount of mist emitted from the mist emission unit 50 in this way, it is possible to suppress unnecessary consumption of mist when performing the processes of S104 to S106 of the ozone sprayer 2 to be described later, and to rapidly release ozone regardless of the ambient temperature. The concentration is reduced to the specified level.

Next, the control unit 181 compares the detection signal from the human sensor 160 with the threshold value set in S204 or S206 to determine whether there is a person within a predetermined range from the ozone deodorizer 1 (S208). When no one is present ( S208 : NO) and the ozone is not being released ( S209 : YES), the control unit 181 operates the ozone generator 120 and the fan 130 ( S210 ). Thereby, ozone is discharged from the discharge port 103 of the charger 3 together with the air.

Then, when a person approaches within the predetermined range of the ozone deodorizer 1 while ozone is being emitted, the control unit 181 determines that a person is present ( S208 : YES) and that ozone is being emitted ( S211 : YES). In this case, the control part 181 stops the ozone generator 120 (S212). At this time, the fan 130 continues to operate without being stopped. Thereby, the discharge of ozone from the discharge port 103 of the charger 3 is stopped, and only air is discharged from the discharge port 103 .

Then, the control unit 181 instructs the control unit 81 of the ozone sprayer 2 to generate mist using the short-range wireless communication ( S213 ), and notifies the value of the output of the ultrasonic transducer 520 set in S205 or S207 ( S214 ). After that, when the predetermined time has elapsed since the ozone generator 120 was stopped ( S215 : YES), the control unit 181 stops the fan 130 ( S216 ).

Returning to FIG. 7 , when an instruction to generate mist is received in the ozone sprayer 2 ( S103 : YES), the control unit 81 opens the mist valve 350 ( S104 ), and then operates the pump 230 ( S105 ). Thereby, the water in the container 210 is sent to the mist discharge|release part 50, and is stored in the water storage tank 530. The control unit 81 operates the ultrasonic transducer 520 according to the output notified by the control unit 181 ( S106 ). Thereby, the mist is released from the mist release part 50 . The released mist comes into contact with the ozone remaining around the ozone deodorizer 1 . The remaining ozone is decomposed by the mist, that is, water. As a result, the ozone concentration around the ozone deodorizing device 1 rapidly decreases, and the ozone odor rapidly decreases.

At this time, by the operation of the fan 130, the air, that is, the wind, is sent from the discharge port 103 of the charger to the periphery of the ozone deodorizing device 1. Therefore, the mist is diffused by the wind, and the surrounding of the ozone deodorizing device 1 is prevented from being wetted by the mist. .

When the user removes the ozone sprayer 2 from the charger 3 for cleaning or the like, the control unit 81 determines that the ozone sprayer 2 is removed from the charger 3 ( S107 : YES). The control unit 81 sends a notification of leaving to the control unit 181 of the charger 3 ( S108 ), and the control process of the ozone mode ends.

Returning to FIG. 8 , in the charger 3, after the fan 130 is stopped, if no one exists again within a predetermined range with the ozone sprayer 2 installed on the charger 3, the control unit 181 operates the ozone generator 120 and the fan 130, Ozone is released from the ozone release unit 150 . On the other hand, when it is determined that the ozone sprayer 2 has been separated from the charger 3 by receiving the notification of separation from the control unit 81 of the ozone sprayer 2 ( S217 ), the control unit 81 ends the control process of the ozone mode.

In addition, the control process of the ozone mode by the

control parts

81 and 181 is performed from the beginning immediately after completion|finish.

According to the present embodiment, when someone comes to the vicinity of the ozone deodorizing device 1 while ozone is being released from the ozone release part 150, the ozone remaining in the vicinity is decomposed by the mist released from the mist release part 50, the concentration of which is rapidly decreased, and the ozone smells rapidly weakened. Thereby, it can make it difficult for a person to feel uncomfortable.

Furthermore, according to the present embodiment, the human-sensing sensor 160 that outputs a detection signal that changes according to the magnitude of the temperature change caused by the infrared rays emitted by a person is provided, and the presence or absence of a person is determined by comparing the detection signal with a predetermined threshold value. . And the threshold value is adjusted so that a person exists based on the temperature change which becomes large as the surrounding temperature of the ozone deodorizer 1 becomes low. As a result, fluctuations in the detection range of human presence due to changes in ambient temperature can be suppressed, so that it is less likely that the ozone deodorizing device 1 does not stop releasing ozone regardless of whether there is a person near the ozone deodorizing device 1 due to room temperature or the like, or that the ozone deodorizing device does not stop. 1 Whether there is no one in the vicinity and no ozone is emitted.

Furthermore, according to the present embodiment, the lower the ambient temperature of the ozone deodorizing device 1 is, the higher the concentration of ozone discharged from the ozone discharge unit 150 is, the greater the amount of mist discharged from the mist discharge unit 50 per unit time is. Therefore, unnecessary consumption of fog can be suppressed, and the ozone concentration can be quickly reduced to an appropriate level regardless of the ambient temperature, and the ozone odor can be quickly reduced to an appropriate state.

Furthermore, according to the present embodiment, when a person comes to the vicinity of the ozone deodorizer 1 while ozone is being emitted, the ozone generator 120 is stopped to stop ozone emission, while the fan 130 is operated to emit air. Thereby, the mist discharged from the mist discharge part 50 is diffused by the discharged air, and the periphery of the ozone deodorizing apparatus 1 is suppressed from being wetted by the mist.

The embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments and the like, and the embodiments of the present invention may be modified in various ways other than those described above.

For example, in the above-described embodiment, in order to detect whether or not a person exists within a predetermined range from the ozone deodorizer 1, the human sensor 160, which is a thermal infrared sensor, is used. However, a human-sensing sensor other than the thermal-type infrared sensor, and a human-sensing sensor other than the infrared sensor can also be used. When a human sensor other than such a thermal infrared sensor is used, the processing of S204 and S206 in FIG. 8 , that is, the adjustment of the threshold value based on the ambient temperature is not performed during the operation in the ozone gas mode.

In addition, in the above-described embodiment, in the operation of the ozone gas mode, the amount of mist discharged per unit time from the mist discharge unit 50 is adjusted according to the ambient temperature. However, regardless of the ambient temperature, the amount of mist emitted per unit time may be constant. In this case, the amount of mist emitted may be determined according to the time when the ambient temperature is low and the ozone concentration becomes high.

Furthermore, in the above-described embodiment, in the operation of the ozone gas mode, when the presence of a person is detected and the ozone generator 120 is stopped while the ozone is being emitted, the fan 130 continues to operate. However, the fan 130 may also be controlled to be temporarily stopped together with the ozone generator 120 and restarted thereafter. Furthermore, when the periphery of the ozone deodorizing device 1 is not easily wetted by the mist due to the amount of mist released, the fan 130 may be stopped together with the ozone generator 120 and then not operated.

Furthermore, in the above-described embodiment, the mist discharger 50 adopts a configuration in which the water stored in the water storage tank 530 is discharged by the ultrasonic vibration of the ultrasonic vibrator 520 . However, the mist discharge part 50 is not limited to the above-mentioned structure, and may be, for example, a structure having a nozzle having a hole diameter for discharging water in a mist form.

Moreover, in the said embodiment, the mist is discharged|emitted in the horizontal direction from the mist discharge|release part 50 of the ozone sprayer 2 in the state in which the ozone sprayer 2 was horizontal. However, the mist may be released obliquely downward from the ozone sprayer 2 by inclining the mist releasing part 50 or the like. In this way, the emitted mist easily intersects with the ozone emitted obliquely upward from the charger 3 to be easily mixed with the ozone, and the ozone is easily decomposed by the mist.

Moreover, in the said embodiment, the ozone deodorizing apparatus 1 consists of the ozone sprayer 2 and the charger 3. However, the structure of the ozone deodorizing apparatus 1 is not limited to this structure. For example, the ozone deodorizing device 1 may be constituted by only the ozone sprayer 2, and the ozone discharge part 150 originally provided in the charger 3 may be provided on the bottom of the casing 10. In this case, the AC adapter may be connected to the ozone sprayer 2 , and the electric power for charging is supplied from the AC adapter to the ozone sprayer 2 .

Furthermore, the ozone deodorizing device 1 may be constituted by a mist discharge part that discharges only mist not containing ozone and a discharge part that discharges ozone. For example, an ozone discharger may be provided at the bottom of a nebulizer that does not have an ozone generating function but can discharge only mist. the ozone emission part.

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