Please refer to Figures 1 to 4, which show an ozone disinfection and drying device according to an embodiment of the present invention, wherein Figure 1 is a schematic perspective view thereof, Figure 2 is a schematic front view (door omitted), and Figure 3 is a block diagram of the device Figure 4 shows a block diagram of the connection between the sensing and monitoring device and peripheral devices.

The ozone disinfection and drying device 100 of the present invention includes: a sealable cavity 102, a placement device 104 for articles to be treated, a temperature control/humidification/dehumidification device 106, an air intake device 108, an exhaust device 110, an ozone generating device 112, a filter The component 130 , the internal circulation system 114 of the cavity, the sensing and monitoring device 125 and the display/control interface 124 .

The closable chamber 102 is, for example, a rigid, ozone-resistant, and well-sealed box, which is closed by a door 150 , and its shape can be determined according to the size of the space used. The cavity 102 is provided with a filter element 130 on both the intake side and the exhaust side. The filter element 130 is used for preliminary filtering of the ambient air entering the cavity 102 and the gas discharged from the cavity 102 . Of course, if the environment outside the cavity 102 is good, such as clean air, no dust, fresh smell, and dry, etc., the filter element 130 on the intake side may be omitted as appropriate. The filter element 130 on the exhaust side is for removing ozone, so it cannot be omitted.

The clothes placing device 104 is a shelf or a pole arranged in the cavity 102, or it can be a multi-layer movable grid for placing various clothes, raincoats, rain boots, shoes, bedding, towels, etc.

The temperature control/humidification/dehumidification system 106 includes a dehumidification device 106a, a humidification device 106b and a temperature control device 106c.

The sensing and monitoring device 125 includes a humidity sensor 116 , a temperature sensor 118 , an ozone concentration sensor 120 and a control unit 122 .

The cavity internal circulation system 114 includes circulation pipelines and various valves, and is controlled by the control unit 122 to perform internal circulation actions.

The cavity 102 is provided with a display/control interface 124 connected with the control unit 122 . Control unit 122 is also connected to temperature sensor 118, humidity sensor 116, ozone concentration sensor 120, dehumidifier 106a, humidifier 106b, air inlet device 108, exhaust device 110, ozone generator 112 and cavity Internal circulatory system 114 . The display/control interface 124 allows the user to select the drying and disinfection mode, and the degrees of drying, deodorization, and disinfection can be divided into strong, medium, and weak levels, and the time for taking the processed items can also be scheduled , which is similar to the operation panel of a general washing machine, and can also display the temperature, humidity and ozone concentration status in the existing cavity 102 . Of course, the degree of drying, deodorization and disinfection is not necessarily divided into three levels, and can be divided into more finer points, or less.

The air intake device 108 and the exhaust device 110, such as a combination of a valve and a fan, are controlled by the control unit 122 to discharge the gas in the cavity 102 through the filter element 130 on the exhaust side, and make the gas outside the cavity 102 The outside air (ambient air) enters the cavity through the filter element 130 on the intake side.

This device can use outside air as the gas source of the ozone generating device 112, and can also use an oxygen bottle as the gas source of the ozone generating device 112. Thereby, the ozone generator 112 here can have following several changes:

(1) The UV ozone generator 112a cooperates with the outside air after drying and filtering to generate ozone:

At this time, a dehumidification filter element 140 (as shown in FIG. 3 ) can be added on the intake side of the cavity 102, so that the outside air entering the cavity 102 is pre-filtered and dried before being used as the air of the UV ozone generator 112a. source, from which ozone is produced.

(2) UV ozone generator 112a cooperates with oxygen cylinder 112b to generate ozone:

At this time, the oxygen in the oxygen bottle 112b, that is, dry pure oxygen, is used as the gas source of the UV ozone generator 112a, and ozone is generated accordingly. That is to say, the part framed by a dotted line in FIG. 3 is replaced with FIG. 5A.

(3) The corona discharge ozone generator 112c cooperates with the oxygen bottle 112b to generate ozone:

At this time, the oxygen in the oxygen cylinder 112b, that is, dry pure oxygen, is used as the gas source of the corona discharge ozone generator 112c, and ozone is generated accordingly. That is to say, the part framed by a dotted line in FIG. 3 is replaced with FIG. 5B.

In the above structure, if the outside air is used as the ozone generating gas source, part of the air needs to pass through the dehumidification and filter element 140 provided on the intake side of the cavity 102 to generate a dry zero air (zero air means no air) when taking in air. Ozone air), then enter the UV ozone generator 112a. The dehumidifying and filtering element 140 of this embodiment, for example, may be a filtering element including activated carbon, which is used for pre-filtering and drying the air that is about to enter the UV ozone generator 112a. In this situation, the dehumidifying and filtering element 140, the UV odor generator 120a, and the humidifying device 106b are sequentially connected in sequence.

In the above-mentioned structure, if the oxygen cylinder 112b is used as the gas source for ozone generation, then the oxygen cylinder 112b, the ozone generator (UV ozone generator 112a or corona discharge ozone generator 112c) and the humidifier 108 are followed by the flow sequence connect.

According to the characteristics of the present invention, dry pure oxygen or dry filtered outside air is used as the gas source of the ozone generating device, so nitrogen oxides will not be generated along with the production of ozone.

The dehumidification device 106a of the present invention may be a device based on the principle of a general dehumidifier, and performs dehumidification directly in the cavity 102 to dry the items to be treated. It is worth noting that high temperature is detrimental to the disinfection properties of ozone, so the dehumidification here is to use low temperature dehumidification, preferably at a temperature below 60 degrees Celsius, and more preferably at room temperature.

The temperature sensor 118 and the humidity sensor 116 arranged in the cavity 102 can feed back the measured humidity to the control unit 122 arranged in the cavity 102, and the control unit 122 is connected to the dehumidification device 106a, so that the The invention can monitor the temperature and humidity.

The humidifying device 106b here is, for example, an ultrasonic nebulizer for generating proper atomized water vapor. When the control unit 122 passes the ozone through the atomized water vapor, ozone with proper humidity can be generated. The control unit 112 then controls the circulation system 114 in the chamber to circulate the ozone with appropriate humidity in the chamber 102 to carry out the disinfection step. When the control unit 112 deactivates the humidifying device 106b, the dry ozone can be circulated in the cavity 102 . By first setting the humidity value of the humidifying device 106b, and then connecting the humidifying device 106b to the control unit 122, the humidifying device 106b can be controlled, and the humidity in the cavity 102 can also be controlled.

The ozone concentration sensor 120 that is located in the cavity 102 can feed back the measured ozone concentration to the control unit 122, and the control unit 122 is connected to the ozone generator 112 (UV ozone generator 112a or corona discharge ozone generator 112c), the ozone concentration can be monitored.

In the cycle step of drying ozone and ozone with proper humidity, the ozone concentration and temperature and humidity in the cavity 102 are maintained within a preset range through a monitoring method. For example, with the different materials (such as cotton, chemical fiber, wool, silk, etc.) and the state (not too dirty, very wet, strong smell... etc.) The default scope of the class. The preset range includes an ozone concentration parameter range, a humidity parameter range, a processing time range, and the like. The monitoring method, for example, is to measure the ozone concentration and temperature and humidity in the cavity, and perform the steps of generating ozone, humidifying the ozone, and controlling the temperature (realized by the temperature control device 110) according to the measurement results, so as to control the cavity The environment in the body is controlled in an appropriate deodorizing and disinfecting environment. Wherein, the step of generating ozone is that the control unit 122 controls the start and stop of the ozone generating device 112 to control the ozone concentration. The step of ozone humidification is that the control unit 122 controls the start and stop of the humidifier 106a and the dehumidifier 106b to control the ozone humidity. The humidity parameter is, for example, a relative humidity of 40% to 90%RH. The temperature parameter range is, for example, below 60 degrees Celsius, preferably in the normal temperature range.

According to a feature of the present invention, objects can be more effectively sterilized by using circulation of ozone having an appropriate humidity in addition to dry ozone.

The control unit 122 utilizes the ozone concentration sensor 120, the temperature sensor 118, the humidity sensor 116 and the timer (the general control unit is equipped with a timer, if not, it can be added additionally) to confirm whether the processing of the clothes is completed Steps, etc., such as judging whether the expected time has been reached, or whether the predetermined ozone concentration range has been reached, so as to judge that the above steps have been completed. The control unit 122 determines whether to continue to maintain the cavity 102 at the position according to the user's setting in the display/control interface 124, such as "use the clothes immediately after processing" or "do not take the clothes after processing". A bacteriostasis state, that is, maintaining the ozone concentration at a certain level suitable for bacteriostasis.

When the user determines to take out the clothes immediately, or when the preset take-out schedule has been reached (for example, two hours after the disinfection is completed, or specify the exact time for taking out, etc.), the ozone removal step is performed. , the control unit 122 makes the gas in the cavity 102 (containing ozone components at this time) pass through the exhaust device 110 and the filter element 130 on the exhaust side to remove the ozone in the cavity 102, and then discharge it into the environment outside the cavity 102 , and at the same time, the control unit 112 activates the air intake device 108 to allow the ambient air outside the cavity 102 to enter, so as to gradually reduce the ozone concentration in the cavity 102 . And when the ozone concentration in the cavity 102 drops to an allowable safe range, the control unit 122 can display this message to the display/control interface outside the cavity 102 to inform the user that the clothes are available. It is also possible to make the control unit 122 control the locking of the door 150, that is, when the safe range of ozone concentration is not reached, the door 150 is locked to avoid opening by mistake.

According to the features of the present invention, the sensing and monitoring device 125 of the present invention continuously monitors during the cycle of dry ozone and the cycle of ozone with appropriate humidity, so that the cavity 102 can be maintained at a suitable temperature for disinfection. Environment.

Moreover, the sensing and monitoring device 125 of the present invention continuously monitors during the taking process of completing disinfection and drying, thus ensuring that the articles are taken only after the ozone concentration reaches a safe range.

The present invention takes slightly different processing steps for unwetted and wetted items to be treated, such as clothing, raincoats, rain boots, bedding, towels, and the like. It can be realized through the automation button interface displayed in the display/control interface 124, and its basic flow is shown in FIG. 6 .

The ozone disinfection and drying method of the present invention is suitable for disinfecting articles in a sealable cavity, comprising the following steps:

Step S100 : providing dry ozone in the cavity 102 and circulating the dry ozone in the cavity 102 . This step can be by providing dry pure oxygen (for example provided by oxygen bottle 112b) and via discharge method, such as UV discharge method (can be realized by UV ozone generator 112a), corona discharge method (can be realized by corona discharge generator 112c), Produces dry ozone. In addition, this step can also produce dry ozone by providing filtered outside air (for example, making outside air enter the cavity 102 through the filter element 130 on the intake side), and generating dry ozone via the UV discharge method (which can be realized by the UV ozone generator 112a) .

Step S200 : providing ozone with a predetermined humidity in the cavity 102 , and circulating the ozone with the predetermined humidity in the cavity 102 . This step includes subjecting the dry ozone to a humidification process, for example passing the dry ozone through the humidifying device 106b to have the predetermined humidity. The humidifying device 106b is, for example, a humidifier capable of generating atomized water vapor. Ozone with a predetermined humidity is generated by making dry ozone atomize water vapor.

Step S300 : Sensing the temperature, humidity and ozone concentration in the cavity 102 . This step can be realized by the temperature sensor 118 , the humidity sensor 116 , and the ozone concentration sensor 120 of the sensing monitoring device 125 arranged in the cavity 102 .

Step S400: According to the measured temperature, humidity and ozone concentration, control the supply of dry ozone and ozone with a predetermined humidity, and control the temperature so that the temperature, humidity and ozone concentration in the cavity are maintained within a preset range. This step can be realized by controlling the temperature control/humidification/dehumidification system 106 by the control unit 122 of the sensing monitoring device 125 . The preset range includes the range of ozone concentration parameters, the range of humidity parameters and the range of processing time that are predetermined according to the different materials and states of the items. For example, the range of the humidity parameter is 40%-90% RH, and the range of the temperature parameter is below 60 degrees Celsius, preferably a normal temperature range.

Step S500: Make the ozone concentration in the cavity 102 reach the safe range allowed by the human body before taking the articles. This step comprises: the gas containing ozone in the chamber 102 is discharged to the outside of the chamber 102 after being filtered (for example, through the filter element 130 on the exhaust side), and the ambient gas outside the chamber 102 is allowed to enter at the same time to reduce the ozone concentration. And monitor the ozone concentration in the cavity 102, when the ozone concentration reaches the safe range allowed by the human body, it is allowed to take the article. Here, allowing access to items includes: sending a notification to the user, for example, sending a notification to the user through the display/control interface 124 . Other items allowed to be taken may include locking the chamber before supplying dry ozone, for example, enabling the control unit 122 to control the locking of the door 150, and unlocking the chamber when the ozone concentration reaches a safe range allowed by the human body.

In the above steps, depending on the condition of the articles to be treated, before the step of providing dry ozone, a dehumidification step can be added appropriately, and the dehumidification device in the temperature control/humidification/dehumidification system 106 can be used to dehumidify the cavity. In the low-temperature dehumidification step, the temperature is below 60 degrees Celsius.

Each process is described in detail below. Please refer to Fig. 7 and Fig. 8 again, wherein Fig. 8 shows the processing flow for wetted articles to be processed, and Fig. 7 is the processing flow for non-wetted articles to be processed. The difference between the two figures is that Fig. 8 adds A dehumidification step.

First, put the articles to be processed into a closeable cavity 102, which is a rigid, ozone gas corrosion-resistant, well-sealed box, which is closed by a door 150, and its shape can be adjusted according to the use space. depends on the size. Moreover, multi-layer movable grids can be set in the cavity 102 according to the needs of the clothes to be treated, such as the aforementioned placing device 104, for placing various clothes, raincoats, rain boots, shoes, bedding, towels, etc.

Through a display/control interface 124 provided outside the cavity 102 , the user selects a drying and disinfection mode, such as powerful drying, powerful deodorization, and powerful disinfection modes. The degree of drying, deodorization and disinfection can be divided into strong, medium and weak. The display/control interface 124 can also set the operating time, which is similar to the operating panel of a general washing machine, and can also display the temperature, humidity, and ozone concentration status of the existing cavity. For example, if the item to be treated is wet, such as being wet by rain, you can use the powerful drying mode; if it is contaminated with a strong smell due to work and other factors, you can use the strong drying mode. Deodorization mode; if you pass through a place with heavy sickness, or during the flu season, you can choose a strong disinfection mode. In short, it can be adjusted by the user at will. Of course, the various modes are not limited to being divided into three types: strong, medium, and weak, as explained above.

Various options on the display/control interface 124 correspond to different materials (such as cotton, chemical fiber, wool, silk, etc.) and states (not too dirty, very wet, heavy smell, etc.) of the items to be processed To various treatment formulas, such as various predetermined ozone concentration parameter ranges, humidity parameter ranges and treatment time ranges...etc. The humidity parameter is, for example, a relative humidity of 40% to 90%RH.

When the user selects the mode and confirms it, the operation is activated according to its setting.

During the activation operation, at first the ambient air in the cavity 102 is discharged by the exhaust device 110 provided in the cavity 102, and the ambient air outside the cavity 102 (i.e. outside air) is entered into the cavity 102 (step S10 ). This is the so-called exhaust action, which is the initial action of a general disinfection procedure.

Next will produce ozone, the mode of producing ozone is as explained above, can use ozone generating device 112 to generate ozone, and as the gas source of ozone generating device 112 can be dry pure oxygen, also can be the external air after filtering .

When using outside air as the air source, make a part of the air entering the cavity 102 pass through the dehumidification and filter element 140 provided in the cavity 102 to produce a dry zero air (zero air means ozone-free air), As the gas source of UV ozone generator 112a. The dehumidifying and filtering element 140 of this embodiment, for example, may be a filtering element including activated carbon, which is used for pre-filtering and drying the air that is about to enter the UV ozone generator 112a.

When the article to be treated is in a relatively humid state, the article will be dehumidified before disinfection (step S15 in Figure 8), that is, the dehumidification device 106a in the temperature control/humidification/dehumidification system 106 is used to dehumidify the cavity 102 , otherwise skip to the next step directly. It is worth noting that high temperature is detrimental to the disinfection properties of ozone, so the dehumidification here is to use low temperature dehumidification, preferably at a temperature below 60 degrees Celsius, and more preferably at room temperature.

The dry zero air obtained after passing through the above-mentioned dehumidification and filter element 140 is introduced into the UV ozone generator 112a set in the cavity 102 to generate dry ozone (step S20), and pass through the cavity set in the cavity 102 The internal circulation system 114 circulates the dry ozone in the cavity 102 (step S30 ), and performs natural exhaust, thereby performing the deodorizing and deodorizing steps. In this step, the humidifying device 106b is not activated temporarily, so the circulation is dry ozone. And because the air in the cavity 102 is dehumidified and pre-filtered by the filter element 140 before being introduced into the UV ozone generator 112a, the efficiency of ozone generation can be improved and the life of the ozone generator can be extended. Of course, in the above steps, the oxygen bottle 112b can also be directly used as the intake source of the UV ozone generator without using ambient air.

Make the humidifying device 106b set in the cavity 102, such as an ultrasonic nebulizer, generate appropriate moisture, and make the dry ozone pass through the moisture to generate ozone with appropriate humidity (step S40), and pass through the cavity The chamber internal circulation system 114 provided in the chamber 102 circulates the ozone with appropriate humidity in the chamber 102 (step S50 ) to carry out the disinfection step. By connecting the humidifying device 106b to the control unit 122, the humidifying device 106b can be controlled.

The above-mentioned generation of dry ozone, generation of ozone with appropriate humidity, and circulation thereof are carried out under the monitoring of the sensing and monitoring device (step S60). That is, the generation and circulation of dry ozone will continue until the preset conditions are met, for example, until the temperature, humidity and ozone concentration in the cavity 102 reach the preset temperature, humidity and ozone concentration ranges for a preset time. Specifically, the measured temperature, humidity and ozone concentration can be fed back to the device through the humidity sensor 116, temperature sensor 118, and ozone concentration sensor 120 of the sensing and monitoring device 125 arranged in the cavity 102. The control unit 122 of the sensing monitoring device 125 in the cavity 102 can monitor the temperature, humidity and ozone concentration by controlling the temperature control/humidification/dehumidification system 106 and the ozone generating device 112 through the control unit 122 . And the generation and circulation of ozone with appropriate humidity will continue until the preset conditions are met, for example, until the preset temperature, humidity and ozone concentration are reached and last for a preset time. The preset time mentioned above is the time schedule preset in the control unit 122, for example, the cycle of dry ozone is 10 minutes, the cycle of ozone with appropriate humidity is 20 minutes, etc., which are data obtained according to a large number of experiments.

The control unit 122 of the sensing monitoring device 125 utilizes a timer (the general control unit is provided with a timer, if there is no timer, it can be added additionally) to confirm whether the above-mentioned deodorization and deodorization, disinfection steps, etc. have been completed, such as judging whether it has reached the expected Time, or whether it has reached the predetermined ozone concentration range, so as to judge that the above steps have been completed. The control unit 122 determines whether to continue to maintain the cavity at a certain level according to the user's settings in the display/control interface 124, such as "use the clothes immediately after processing" or "do not take the clothes after processing". Bacteriostatic state (step S70 ), that is, maintaining the ozone concentration at a level suitable for bacteriostasis.

When the user determines to take out the clothes immediately, or when the preset take-out schedule has been reached, the ozone removal step is performed, so that the gas in the cavity 102 (containing ozone at this time) passes through the exhaust device 110 and the filter element 130 , remove the ozone component in the chamber 102, then discharge into the environment outside the chamber 102, and simultaneously allow the ambient gas (outside air) outside the chamber 102 to enter to gradually reduce the ozone concentration in the chamber 102 (step S80) . And when the ozone concentration in the cavity 102 drops to the safe range allowed by the human body, the control unit 102 can display this message to the display/control interface outside the cavity 102 to notify the user that the item is available. It is also possible to make the control unit 122 control the locking of the door 150, that is, when the safe range of ozone concentration is not reached, the door 150 is locked to avoid opening by mistake. In addition, before taking the article, it can also be dried according to the situation (this is the optional step S75), because the disinfection step has been completed, so the drying step here does not limit the temperature, and it can be properly adjusted depending on the material of the article. drying.
