The closable cavity 102 is, for example, a rigid, well-sealed, corrosion-resistant cabinet that is sealed by a door 150, the shape of which can vary depending on the size of the space used. The chamber 102 is provided with a filter assembly 130 on both the intake side and the exhaust side. The filter assembly 130 is for preliminarily filtering the outside air entering the chamber 102 and the gas discharged from the chamber 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 assembly 130 on the intake side may be omitted as appropriate. The filter assembly 130 on the exhaust side is for the purpose of removing ozone and cannot be omitted.

The item placing device 104 to be processed is a rack, a rod or the like provided in the cavity 102, or may be a multi-layer movable grille for various clothes, raincoats, rain boots, shoes, bedding articles, towels, etc. Place.

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

The sensing 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 a circulation line and various valve bodies, and is controlled by the control unit 122 to perform an internal circulation operation.

A display/control interface 124 is disposed outside the cavity 102 and is coupled to the control unit 122. The control unit 122 is also connected to the temperature sensor 118, the humidity sensor 116, the ozone concentration sensor 120, the dehumidification device 106a, the humidification device 106b, the air intake device 108, the exhaust device 110, the ozone generating device 112, and the cavity. Internal circulation system 114. The display/control interface 124 can be used by the user to select a dry and disinfection mode, and the degree of drying, deodorization, and disinfection can be divided into strong, medium, and weak degrees, and the time of the processed items can be scheduled. It is similar to the operation panel of a general washing machine, and can also display the temperature and humidity and the ozone concentration state in the existing cavity 102. Of course, the degree of drying, deodorization and disinfection is not necessarily divided into three levels, which can be divided into finer and more, or less.

The air intake device 108 and the exhaust device 110 are, for example, a combination of a valve body and a fan, and are controlled by the control unit 122 to discharge the gas in the cavity 102 through the filter assembly 130 on the exhaust side, and the cavity 102 is caused. The outer peripheral air (ambient air) enters the cavity through the filter assembly 130 on the intake side.

The apparatus may use peripheral air as a gas source for the ozone generating device 112, or an oxygen cylinder may be used as a gas source for the ozone generating device 112. Thus, the ozone generating device 112 herein can have the following changes:

(1) The UV ozone generator 112a cooperates with the dried and filtered peripheral air to generate ozone:

At this time, a dehumidifying and filtering assembly 140 (FIG. 3) may be added to the intake side of the cavity 102 to allow the ambient air entering the cavity 102 to be pre-filtered and dried before being used as the UV ozone generator 112a. The source of gas and the ozone produced accordingly.

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

At this time, oxygen in the oxygen cylinder 112b, that is, dry pure oxygen is used, as a gas source of the UV ozone generator 112a, and ozone is generated accordingly. That is, the portion of the broken line frame of Fig. 3 is replaced with Fig. 5A.

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

At this time, the oxygen in the oxygen cylinder 112b, that is, the pure oxygen is dried, is used as The gas source of the ozone generator 112c is corona-discharged, and ozone is generated accordingly. That is, the portion of the broken line frame of Fig. 3 is replaced with Fig. 5B.

In the above configuration, if the ambient air is used as the ozone generating gas source, the intake air is required to generate a dry zero air through the dehumidifying and filtering unit 140 provided on the intake side of the chamber 102 through the chamber 102 (zero air representation). The ozone-free air) is then passed to the UV ozone generator 112a. The dehumidification and filtration module 140 of the present embodiment may be, for example, a filter element containing activated carbon for pre-filtering and drying the air that is about to enter the UV ozone generator 112a. In this case, the dehumidification and filtration unit 140, the UV odor generator 112a, and the humidification unit 106b are connected in the order of the flow path.

In the above configuration, if the oxygen cylinder 112b is used as the gas source for ozone generation, the oxygen cylinder 112b, the ozone generator (the UV ozone generator 112a or the corona discharge ozone generator 112c), and the humidifying device 106b are in the flow path sequence. Connect in order.

According to a feature of the present invention, dry pure oxygen or dry filtered peripheral air is used as a gas source for the ozone generating device, so that nitrogen oxides are not generated along with the production of ozone.

The dehumidifying device 106a of the present invention may be a general dehumidifier principle device that performs a dehumidifying action directly in the cavity 102 to make the item to be treated dry. It is worth noting that the high temperature is unfavorable for the disinfecting characteristics of ozone. The dehumidification here is a low temperature dehumidification, preferably a temperature below 60 degrees Celsius, and more preferably a dehumidification at room temperature.

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

The humidifying device 106b here is, for example, an ultrasonic atomizer for generating an appropriate atomized moisture. When the control unit 122 passes ozone through the atomized water vapor, ozone having an appropriate humidity can be generated. The control unit 122 then controls the internal cavity circulation system 114 to circulate ozone having the appropriate humidity within the cavity 102 for the sterilization step. When the control unit 122 does not operate the humidifying device 106b, dry ozone can be circulated within the cavity 102. The humidifying device 106b can be controlled by first setting the humidity value of the humidifying device 106b and then connecting the humidifying device 106b to the control unit 122, that is, the humidity in the cavity 102 can be controlled.

The ozone concentration sensor 120 disposed 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 generating device 112 (the UV ozone generator 112a or the corona discharge ozone generator). 112c), the ozone concentration can be monitored.

In the recycling step of drying ozone and ozone with appropriate humidity, the ozone concentration and temperature and humidity in the chamber 102 are maintained within a predetermined range via a monitoring method. For example, experiment with the material of the item to be treated (such as cotton, chemical fiber, wool, silk, etc.) and the state (not too dirty, very wet, heavy taste, etc.) The range of presets tested. This preset range includes the ozone concentration parameter range, the humidity parameter range, and the processing time range. The monitoring method is, for example, measuring the ozone concentration and the temperature and humidity in the cavity, and performing the steps of generating ozone according to the measurement result, the step of humidifying the ozone, and the temperature control step (achieved by the temperature control device 106c) to The environment in the chamber is controlled in an appropriate deodorizing and disinfecting environment. Here, in the step of generating ozone, the control unit 122 controls the operation and the stop of the ozone generating device 112 to control the ozone concentration. In the step of humidifying ozone, the control unit 122 controls the operation and stop of the humidifying device 106b and the dehumidifying device 106a to control the ozone humidity. The humidity parameter is, for example, a relative humidity of 40% to 80%. The temperature parameter range is, for example, 60 degrees Celsius or less, preferably a normal temperature range.

According to a feature of the present invention, in addition to drying ozone, a cycle of ozone having an appropriate humidity can be utilized to more effectively sterilize articles.

The control unit 122 utilizes the ozone concentration sensor 120, the temperature sensor 118, the humidity sensor 116, and a timer (the general control unit is attached with a timer) If it is not, it can be additionally added to confirm whether the processing steps of the laundry are completed, for example, whether the estimated time has been reached, or whether the predetermined ozone concentration range has been reached, and it is judged that the above steps have been completed. The control unit 122 determines whether to continue to maintain the cavity 102 according to the setting of the user in the display/control interface 124, for example, "receiving the laundry after processing" or "processing the temporarily not taking clothes". The bacteriostatic state, that is, maintaining the ozone concentration to a degree suitable for bacteriostatic.

When the user determines that the laundry is to be taken out immediately, or if the preset removal schedule has been reached (for example, two hours after the sterilization is completed, or the exact time of the access is specified), the ozone removal step is performed. The control unit 122 passes the gas in the cavity 102 (the ozone component at this time) through the exhaust device 110 and the filter assembly 130 on the exhaust side to remove the ozone in the cavity 102 and discharge it into the environment outside the cavity 102. At the same time, the control unit 122 operates the air intake device 108 to allow ambient gas outside the cavity 102 to enter to gradually reduce the ozone concentration in the cavity 102. And when the concentration of ozone in the chamber 102 falls to an acceptable safe range, the control unit 122 can display this message to the display/control interface outside the chamber 102 to inform the user that the laundry is available. It is also possible for the control unit 122 to control the locking of the door 150, i.e., to lock the door 150 when the safe range of ozone concentration is not reached, to avoid false opening.

According to a feature of the invention, the sensing monitoring device 125 of the present invention is Monitoring is continuously performed during the cycle of dry ozone and during the cycle with appropriate humidity ozone, thereby maintaining the chamber 102 in an environment suitable for sterilization.

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

The present invention takes slightly different processing steps for unwetted and wet objects to be treated, such as clothing, raincoats, rain boots, bedding utensils, towels, and the like. This can be achieved by an automated button interface displayed in the display/control interface 124, the basic flow of which is illustrated in FIG.

The ozone sterilization drying method of the present invention is suitable for sterilizing articles in a closable cavity, including the following steps:

Step S100: providing dry ozone in the cavity 102 and circulating the dried ozone in the cavity 102. This step can be achieved by providing dry pure oxygen (for example, provided by oxygen cylinder 112b) and via a discharge method such as a UV discharge method (achievable by UV ozone generator 112a), a corona discharge method (achievable by corona discharge ozone generator 112c). ), producing dry ozone. In addition, this step can also be accomplished by providing filtered ambient air (eg, passing ambient air into the cavity 102 via the filter assembly 130 on the intake side) and via UV discharge (available by the UV ozone generator 112a) Produces dry ozone.

Step S200: Providing ozone having a predetermined humidity in the cavity 102, and circulating ozone having a predetermined humidity in the cavity 102. This step includes subjecting the dried ozone to a predetermined humidity through a humidification process, such as passing dry ozone through the humidification device 106b. This humidifying device 106b is, for example, a humidifier that can generate atomized water vapor. The dried ozone is passed through the atomized water gas to generate ozone having a predetermined humidity.

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

Step S400: Control the supply of dry ozone and ozone having a predetermined humidity according to the measured temperature, humidity, and ozone concentration, and control the temperature so that the temperature, humidity, and ozone concentration in the chamber are maintained within a predetermined range. This step can be achieved by control of the temperature control/humidification/dehumidification system 106 by the control unit 122 of the sensing monitoring device 125. The preset range includes a predetermined ozone concentration parameter range, a humidity parameter range, and a processing time range depending on the material and state of the article. For example, the humidity parameter ranges from 40% to 80% relative humidity, and the temperature parameter ranges from 60 degrees Celsius to below, preferably in the normal temperature range.

Step S500: Before the article is taken, the ozone concentration in the cavity 102 is made to reach a safe range acceptable to the human body. This step includes: including the cavity 102 The ozone-laden gas is discharged to the outside of the chamber 102 via filtration (e.g., via the filter assembly 130 on the exhaust side) while allowing ambient gas outside the chamber 102 to enter to reduce the ozone concentration. The ozone concentration in the cavity 102 is monitored, and when the ozone concentration reaches the safe range allowed by the human body, the article is allowed to be taken. The allowed access to the item herein includes: notifying the user, for example, by notifying the user via the display/control interface 124. Further allowable items may also include locking the cavity prior to providing dry ozone, such as by the control unit 122 controlling the locking of the door 150 to release the locking of the cavity when the ozone concentration reaches a safe range acceptable to the human body.

In the above steps, the condition of the item to be processed is more visible, and the dehumidification step is appropriately added before the step of providing dry ozone, and the dehumidification device in the temperature control/humidification/dehumidification system 106 can be used to dehumidify the cavity. A low temperature dehumidification step at a temperature below 60 degrees Celsius.

The following describes each process in detail. Please refer to FIG. 7 and FIG. 8 again, wherein FIG. 8 illustrates the processing flow of the wetted articles to be processed, and FIG. 7 is the processing flow of the unwoiled articles to be processed, and the difference between the two figures is that FIG. 8 is added. A dehumidification step.

First, the object to be treated is placed into a closable cavity 102, which is a rigid, well-sealed box that is rigid, ozone-resistant, and sealed by the door 150. Its shape can be used according to the use. The size of the space depends. And the cavity 102 can be provided with a plurality of movable grilles according to the needs of the laundry to be processed, such as the aforementioned object placing device 104, for various clothes, raincoats, rain boots, shoes, bedding articles, towels, etc. Place.

The user selects the dry disinfection mode via a display/control interface 124 disposed outside the cavity 102, such as a strong dry, strong deodorization, and a strong disinfection mode. The degree of drying, deodorization, and disinfection can be selected in a strong, medium, or weak manner. The display/control interface 124 can also set the operation time, which is similar to the operation panel of a general washing machine, and can also display the temperature, humidity, and ozone concentration state of the existing cavity. For example, if the item to be treated is in a wet state, for example, in a wet state such as being wet, a strong drying mode may be used; if it is contaminated with a heavy taste due to other factors such as work, a strong force may be used. Deodorization mode; if it is a place with heavy illness, or in the flu season, you can use the powerful disinfection mode. In short, it can be adjusted by the user. Of course, the various modes are not limited to being divided into three types: strong, medium, and weak, which have already been explained before.

Various options on the display/control interface 124, along with the items to be processed The different materials (such as cotton, chemical fiber, wool, silk, etc.) and the state (not too dirty, very wet, heavy taste, etc.) correspond to various treatment formulas, such as various predetermined ozone concentration parameter ranges. , humidity parameter range and processing time range...etc. The humidity parameter is, for example, a relative humidity of 40% to 80%.

When the user selects the mode and determines it, the operation is initiated according to its settings.

In the start-up operation, the ambient air in the cavity 102 is first discharged through the exhaust device 110 provided in the cavity 102, and the ambient air outside the cavity 102 (ie, the peripheral air) is introduced into the cavity 102 (steps) S10). This is the so-called exhaust action, which is the initial action of the general disinfection procedure.

Next, ozone is generated, and ozone is generated. As explained above, the ozone generating device 112 can be used to generate ozone, and the gas source for the ozone generating device 112 can be dry pure oxygen or filtered perimeter. Empty oxygen.

When ambient air is used as the source of air, a portion of the air entering the chamber 102 passes through the dehumidification and filtration assembly 140 disposed within the chamber 102 to produce a dry zero air (zero air indicates ozone-free air). As a gas source for the UV ozone generator 112a. The dehumidifying and filtering assembly 140 of the present embodiment may be, for example, a filter element containing activated carbon for pre-filtering and drying the air that is about to enter the UV ozone generator 112a. Dry processing.

When the item to be treated is in a relatively wet state, the item is dehumidified prior to sterilization (step S15 of FIG. 8), that is, the inside of the cavity 102 is performed by the dehumidifying device 106a in the temperature control/humidification/dehumidification system 106. Dehumidify, otherwise you can skip to the next step. It is worth noting that the high temperature is unfavorable for the disinfecting characteristics of ozone. The dehumidification here is a low temperature dehumidification, preferably a temperature below 60 degrees Celsius, and more preferably a dehumidification at room temperature.

The dry zero air obtained after the above-described dehumidifying and filtering unit 140 is introduced into the UV ozone generator 112a provided in the cavity 102 to generate dry ozone (step S20), and via the cavity provided in the cavity 102. The circulation system 114 circulates the dry ozone in the cavity 102 (step S30), and performs natural exhausting, thereby performing the deodorization and deodorization step. In this step, the humidifying device 106b does not operate for a while, so the circulating ozone is dry. Moreover, since the air in the cavity 102 is first introduced into the UV ozone generator 112a through the preliminary filtration of the dehumidification and filtration unit 140, the ozone generation efficiency can be improved, and the life of the ozone generator can be prolonged. Of course, the oxygen cylinder 112b can also be used directly as the source of the intake of the UV ozone generator without using ambient air.

The humidifying device 106b provided in the cavity 102, for example, an ultrasonic atomizer, generates appropriate moisture and generates dry ozone through the moisture. Ozone having an appropriate humidity (step S40), and ozone having an appropriate humidity is circulated in the cavity 102 via the cavity internal circulation system 114 provided in the cavity 102 (step S50) to perform a sterilization step. The humidifying device 106b can be controlled by connecting the humidifying device 106b to the control unit 122.

The generation of the above-described dry ozone, the generation of ozone with an appropriate humidity, and the circulation thereof are performed under the supervision of the sensing 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 and humidity in the cavity 102, the ozone concentration reaches the preset temperature and humidity, and the ozone concentration range continues for a predetermined period of time. Specifically, the measured temperature, humidity, and ozone concentration can be fed back to the humidity sensor 116, the temperature sensor 118, and the ozone concentration sensor 120 of the sensing and monitoring device 125 disposed in the cavity 102. The temperature and humidity and the ozone concentration can be monitored by the control unit 122 of the sensing and monitoring device 125 disposed in the cavity 102 and controlling the temperature control/humidification/dehumidification system 106 and the ozone generating device 112 via 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 predetermined temperature and humidity, and the ozone concentration are continued for a predetermined period of time. The preset time is preset to the time schedule of the control unit 122. For example, the cycle of drying ozone is 10 minutes, the cycle of ozone with appropriate humidity is 20 minutes, etc., which is data obtained according to a large number of experiments.

The control unit 122 of the sensing monitoring device 125 uses a timer (the general control unit is provided with a timer, if there is no additional setting), to confirm whether the above deodorizing and deodorizing, disinfecting steps, etc. are completed, for example, whether the prediction has been reached The time, or whether the predetermined ozone concentration range has been reached, determines that the above steps have been completed. The control unit 122 determines whether to continue to maintain the cavity according to the setting of the user in the display/control interface 124, for example, "receiving the clothes after processing" or "processing the clothes temporarily not taken". The state of the bacteria (step S70), that is, maintaining the ozone concentration to a degree suitable for inhibition.

When the user determines that the laundry is to be taken out immediately or has reached the preset take-out schedule, the step of removing the ozone is performed, so that the gas in the cavity 102 (at this time containing ozone) passes through the exhaust device 110 and the filter assembly 130. The ozone component in the cavity 102 is removed, and then discharged into the environment outside the cavity 102, while the ambient gas (perimeter gas) outside the cavity 102 enters to gradually reduce the ozone concentration in the cavity 102 (step S80) ). And when the concentration of ozone in the cavity 102 falls within the safe range allowed by the human body, the control unit 122 can display the message to the display/control interface outside the cavity 102 to notify the user of the accessible item. It is also possible for the control unit 122 to control the locking of the door 150, i.e., to lock the door 150 when the safe range of ozone concentration is not reached, to avoid false opening. In addition, before the item is taken, it can be dried as appropriate (this is optional step S75), because the sterilization step has been completed, so the drying step here is not The temperature is limited, and the material can be properly dried according to the material of the article.

The ozone disinfecting and drying method of the present invention has the same effects as the ozone disinfecting and drying apparatus described above.
