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 that 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 onto 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, the ozone water cannot be made into a mist with a small particle size, and it is difficult to diffuse widely indoors. Therefore, it is difficult to deodorize indoors such as toilets and kitchens 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, the ozone concentration in the air released into the room where people may be present is limited to a low concentration of, for example, 0.1 ppm or less. Therefore, it is difficult to fully deodorize the room with only ozone.

According to the said structure, ozone can be discharged|emitted from a 1st discharge part by operating an ozone generation part and an air blowing part.

In the deodorizing device of the present aspect, the second discharge unit may be configured to include: a container for storing water; an electrolysis unit for generating ozone from the water in the container by electrolysis; and a mist generating unit for generating ozone from the water in the container The mist is generated by the water sent from the container, and the water contains the ozone generated by the electrolysis unit.

According to the said structure, since the mist containing ozone can be discharged|emitted from the 2nd discharge|release part, the deodorizing effect in a room is further improved by the effect|action of the ozone contained in mist.

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

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. Furthermore, by providing the second discharge part in the first discharge part and determining the discharge 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 processing for the operation in the cleaning mode is performed by the control unit 81 of the ozone sprayer 2 , and the processing for the operation in the deodorizing mode is performed by the control unit 81 of the ozone sprayer 2 and the control unit 171 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 171 of the charger 3 .

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

7, 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).

When cleaning objects such as a toilet in a bathroom and 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 processing in the cleaning mode ( S102 to S104 ). That is, the control part 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 and the electrolysis unit 220 (S104). Thereby, the ozone water is sent from the generation part 20 to the rain discharge part 40, and is sprayed from the discharge port 41 of the rain discharge part 40 in a rain-like manner. It should be noted that, although not shown in the flowchart of FIG. 7 , the control unit 81 operates the electrolysis unit 220 after a short period of time after the pump 230 is operated. As a result, electricity can be supplied between the anode and the cathode in a state where the inside of the electrolysis unit 220 is surely filled with water, and it is possible to prevent the shortening of the life of these electrodes and the like.

The pump 230 operates for a predetermined time (for example, 3 seconds), and if the operation button 61 is still pressed after the predetermined time has elapsed, the pump 230 continues to operate until the pressing is released or a limited time (for example, 10 seconds) elapses. While the pump 230 is operating, the ozone water is discharged from the rain discharge unit 40 . In this way, since the ozone water is released in the form of rain, the release amount increases. Therefore, the object is easily wetted sufficiently by the ozone water. The rain valve 340 is locked when the pump 230 and the electrolysis unit 220 are stopped.

In addition, in the process of the cleaning mode, the rain valve 340 is opened before the pump 230 operates, and therefore, the water supply pipe 310 can be prevented from falling off from the discharge port 232 of the pump 230 by the water pressure.

The user installs the ozone sprayer 2 on the charger 3 when performing deodorization in a room such as a bathroom and a kitchen, or when charging the ozone sprayer 2 .

When the ozone sprayer 2 is installed in the charger 3 ( S101 : YES), the control unit 81 performs processing in the cleaning mode ( S105 to S111 ). Since the control unit 81 is to charge the rechargeable battery 710, it instructs the control unit 171 of the charger 3 to transmit power using short-range wireless communication (S105). After that, the control unit 81 waits for a mist generation instruction from the control unit 171 of the charger 3 ( S106 ).

When the control unit 81 receives the mist generation instruction ( S106 : YES), the deodorizing process is executed ( S107 to S109 ). That is, the control part 81 opens the mist valve 350 (S107), and then operates the pump 230 and the electrolysis part 220 (S108). Thereby, the ozone water is transported from the generation part 20 to the mist discharge part 50 and stored in the water storage tank 530 . The pump 230 continues to operate as long as a predetermined amount (for example, about 1 cc) of ozone water is stored in the water storage tank 530 . The water level of the water storage tank 530 at this time is the water level at which at least the vibration surface 521 of the ultrasonic vibrator 520 is submerged. However, the ozone water is not in a state where the water storage tank 530 is full. The mist valve 350 is locked when the pump 230 and the electrolysis unit 220 are stopped.

Next, the control unit 81 operates the ultrasonic transducer 520 (S109). Thereby, the mist containing ozone is released from the vibration surface 521 which is the release port of the mist release part 50 . The emitted mist floats in the air and spreads into the room. The ultrasonic vibrator 520 continues to operate until the time for which substantially all the ozone water stored in the water storage tank 530 is discharged has elapsed.

In the deodorization process, the mist valve 350 is opened before the pump 230 is activated, so that the water supply pipe 310 can be prevented from falling off from the discharge port 232 of the pump 230 by the hydraulic pressure.

In addition, when the 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 . Thereby, the mist tube 330 is prevented from leaking into the casing 10, for example, by 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 while waiting for the mist generation instruction ( S110 : YES), the control unit 81 instructs the control unit 171 of the charger 3 to stop power transmission using 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 sprayer 2 is installed in the charger 3 .

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

FIG. 8 is a flowchart showing control processing of the charger 3 by the control unit 171 .

8, the control part 171 monitors the power transmission instruction from the control part 81 of the ozone sprayer 2 (S201). Then, when there is a power transmission instruction (S201: YES), the control unit 171 drives the inverter 173 (S202).

When the inverter 173 operates, 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.

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

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

When no one exists ( S204 : NO), the control unit 171 executes deodorization processing ( S205 , S206 ). That is, the control part 171 operates the ozone generator 120 and the fan 130 (S205). Thereby, ozone is released from the discharge port 103 of the charger 3 . The released ozone diffuses into the room. Furthermore, the control part 171 instructs the control part 81 of the ozone sprayer 2 to generate mist using the short-range wireless communication (S206).

As described above, at the same timing as the release of ozone, the mist containing ozone is released from the ozone sprayer 2 to the rear of the ozone deodorizer 1 in the same manner as the ozone from the charger 3 based on the instruction to generate the mist. The ozone emitted from the charger 3 is mixed with the mist in the indoor space, and OH radicals are generated by the reaction between the ozone and the mist, that is, water. Since OH radicals have oxidizing power like ozone, not only the ozone from the charger 3 but also the OH radicals are used to deodorize the room. In addition, the room is deodorized by ozone contained in the mist. In particular, when the ozone deodorizing device 1 is used in a toilet, the ammonia odor generated in the toilet is not easily decomposed by ozone alone, but by adding mist, that is, water, the ozone and water are brought into contact with the ammonia odor, thereby promoting the The ammonia odor is decomposed by ozone, so it is easy to reduce the ammonia odor.

In the charger 3, the rear side of the air duct 104 is inclined obliquely upward. Therefore, ozone is released obliquely upward from the release port 103 . Thereby, the ozone discharged from the charger 3 is easily mixed with the mist discharged in the horizontal direction from the mist discharge 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 period of time as the mist is emitted from the ozone sprayer 2 .

As described above, in the present embodiment, the timing of releasing and stopping the ozone from the charger 3 is substantially the same as the timing of releasing and stopping the mist from the ozone sprayer 2 . However, the above timings may not be substantially the same as long as there is an overlapping period between the discharge period of ozone from the charger 3 and the discharge period of the mist from the ozone sprayer 2 . Alternatively, as long as 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 immediately after the release of the mist from the ozone sprayer 2 without overlapping period.

It should be noted that when the presence of a person is detected while the ozone generator 120 and the fan 130 are operating, at least the ozone generator 120 may be stopped.

While 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). Then, when there is an instruction to stop power transmission ( S207 : YES), the control unit 171 stops the inverter 173 ( S208 ). Thereby, the power transmission from the power transmission coil 112 is stopped. The control part 171 returns to S201, and monitors the power transmission instruction from the control part 81 of the ozone sprayer 2 again.

According to the present embodiment, the deodorizing process in which ozone is released from the charger 3 and mist is released 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, so that not only the ozone from the charger 3 but also the OH radicals deodorize the room. . Thereby, it becomes possible to deodorize a room|chamber interior, suppressing the ozone density|concentration low.

Moreover, since the deodorization process is not performed when there exists a person in the vicinity of the ozone deodorizing apparatus 1, it is hard to make a user feel uncomfortable by the contact with the ozone and mist which are discharged|emitted.

Furthermore, according to the present embodiment, since the charger 3 adopts the configuration including the ozone generator 120 that generates ozone from oxygen in the air and the fan 130 that sends the ozone generated by the ozone generator 120 to the outside, it is possible to generate ozone by The generator 120 and the fan 130 operate to emit ozone from the charger 3 .

Furthermore, according to the present embodiment, the ozone sprayer 2 employs a container 210 including a water storage container, an electrolysis unit 220 that generates ozone from the water in the container 210 by electrolysis, and an electrolysis unit 220 that contains the ozone generated by the electrolysis unit 220 sent from the container 210. The mist discharge part 50 which generates mist by the water. Thereby, since the mist containing ozone can be emitted from the ozone sprayer 2, the deodorizing effect in the room is further improved by the action of the ozone contained in the mist.

Furthermore, according to the present embodiment, the control unit 81 of the ozone sprayer 2 and the control unit 171 of the charger 3 are configured to execute the deodorization process based on the fact that the ozone sprayer 2 has been installed in the charger 3 . Thereby, the ozone and mist can be prevented from being released 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 separated from the charger 3 . Ozone and mist are released in a state where ozone and mist are easily mixed, and the deodorizing effect of ozone and 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-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.

Furthermore, in the above-described embodiment, the control unit 171 detects the presence or absence of a person by comparing the detection signal from the human-sensing sensor 160 with the threshold value. However, the presence or absence of a person may be detected inside the human-presence sensor 160 , and a detection signal corresponding to the detection result may be output from the human-presence sensor 160 to the control unit 171 . In this case, only the human detection sensor 160 constitutes the human detection unit of the present invention.

Moreover, in the said embodiment, the ozone deodorizing apparatus 1 may be equipped with an illumination intensity sensor as a person detection part in addition to the human-sensing sensor 160. In this case, when the ozone deodorizing device 1 is used in a dark room without a window or the like, and the surface is very dark, the setting to operate the illuminance sensor is performed. In addition, in the deodorization process of FIG. 8 , the control unit 171 detects whether the room is illuminated by the illuminance sensor, and when the room is not illuminated and no one is present and the human sensor 160 detects that no one is present That is, when it is detected by both the illuminance sensor and the human sensor 160 that no one exists in the vicinity of the ozone deodorizing device 1 , the ozone generator 120 and the fan 130 are operated to discharge ozone from the charger 3 .

In addition, when the ozone deodorizing apparatus 1 is used only in the room where it is dark without illuminating the surface, it is also possible to employ a configuration in which only the illuminance sensor is provided without the human sensor 160 . In this case, the presence or absence of a person around the ozone deodorizing device 1 is detected only by the illuminance sensor.

Furthermore, in the above-described embodiment, the mist discharge unit 50 includes the water storage tank 530 that stores the ozone water from the generating unit 20 and the ultrasonic vibrator 520 that atomizes the ozone water stored in the water storage tank 530 by ultrasonic vibration. However, the mist discharge part 50 is not limited to the above-mentioned structure, and may be, for example, a structure with a nozzle having a hole diameter for discharging ozone water in a mist form.

Moreover, in the said embodiment, although the mist release part 50 and the rain release part 40 are arrange|positioned so that it may mutually face in the opposite direction, you may arrange|position so that it may be lined up so that it may face the same direction.

Furthermore, the generation unit 20 may employ a configuration other than the configuration of 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, a configuration may be adopted in which ozone is generated from air by a discharge-type ozone generator, the ozone is dissolved in water in the container 210 to generate ozone water, and the ozone water is sucked and fed by the pump 230 . Section 30 conveys.

Furthermore, in the above-described embodiment, as a structure for releasing ozone from the discharge port 103 of the casing 100 obliquely upward, 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. way to form the charger 3 . However, in order to achieve the above-mentioned purpose, the discharge port 103 may be the same height as the air duct 104, and the entire air duct 104 may be parallel to the bottom surface of the casing 100, and the outlet 104b of the air duct 104 may be located inside the discharge port 103. A plurality of ventilation plates facing obliquely upward are provided in an up-down arrangement. Further, the entire air duct 104 may be inclined so that the discharge port 103 side becomes higher. Furthermore, it is also possible to employ a configuration in which the fan 130 is arranged in an inclined state in the air duct 104 so as to send air obliquely upward toward the discharge port 103 .

Moreover, in the said embodiment, in the state in which the ozone sprayer 2 is horizontal, the mist is discharged|emitted in the horizontal direction from the mist discharge|release part 50 of the ozone sprayer 2. 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 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, a power switch may be provided in the ozone sprayer 2, and when the power switch is turned off, only charging may be performed without performing deodorization treatment.

Furthermore, in the above-described embodiment, 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.

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 bottom portion of the casing 10 having the ozone releasing portion 150 corresponds to the first releasing portion of the present invention. In this case, the AC adapter may be connected to the ozone sprayer 2 and the electric power for charging may be supplied from the AC adapter to the ozone sprayer 2 .

Moreover, in the said embodiment, in the deodorization process, the mist containing ozone is discharged|emitted from the mist discharge|release part 50 of the ozone sprayer 2. However, the mist not containing ozone may be discharged from the mist discharge unit 50 during the deodorization treatment by performing a predetermined switching operation. In this case, in S108 of FIG. 7 , the control unit 171 operates only the pump 230 .

Moreover, the ozone deodorizing apparatus 1 may be comprised from the discharge part which discharge|releases the mist which does not contain ozone, and the discharge part which discharges ozone, for example, the structure which discharges ozone may be provided in the bottom part of the atomizer which discharges mist.

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.
