Description

Sterilization box using a safety sterilization device in which the amount of sterilant produced in each space is variable}

This relates to a sterilization treatment box using a safety sterilization device that safely sterilizes boxes or spaces where clothes or items are stored by spraying a sterilizer at a safe level that is harmless to the human body and has a variable amount of sterilant produced for each space.

Ozone is a gas that exists in small amounts in the living environment and is beneficial when present in appropriate amounts in the air or liquid, but is toxic when present in large amounts. The toxicity of ozone is that it is a substance with strong oxidizing power and is effective in sterilizing and preventing the growth of microorganisms. In addition, because it is easily decomposed in natural conditions and ultimately returns to oxygen and does not cause secondary pollution, research on sterilization using it is continuing.

Additionally, ozone is easy to manufacture and manage because it uses only oxygen as a raw material, and its oxidizing power is very strong, so it can be applied to all areas for sterilization. In addition, ozone has powerful sterilizing, disinfecting, decolorizing, and deodorizing effects by oxidizing non-degradable substances and converting them into biodegradable substances. The instantaneous sterilizing power of ozone is second only to fluorine, so it is used in fields such as wastewater treatment, water treatment, and sterilization of water resources, and is used in a variety of ways, including semiconductor cleaning processes.

Meanwhile, multipurpose boxes such as living boxes and clothing cases used at home are used to store clothing, children's toys, and various other items. Items stored in these multipurpose boxes have bacteria and odors left on them after use, so most use UV-LED sterilizers using UV light to remove them. In this way, sterilization using UV light is often used at home, but only the surface exposed to light is sterilized, so the sterilization area when loading the product is approximately 10%, which has a low sterilization effect, resulting in the problem of not being able to remove germs and odors.

In Republic of Korea Public Utility Model No. 20-2011-0008136, “Ozone Sterilizer,” a clothing cover is posted to remove household odors and bacteria such as food and cigarette smells on clothes by releasing ozone from the cover for a hanger. . These ozone sterilizers could not be used safely because they generated the number of ozone molecules per hour rather than the volume of space. In addition, the ozone sterilizer has a built-in ozone generating means and cannot be separated, so it can only be used within the installed ozone sterilizer, so its usability has been greatly reduced.

Recently, as consumers' awareness of germs has increased following COVID-19, demand for sterilizing products has increased, and ozone is being actively used to prevent COVID-19 in the United States, Canada, and Brazil. As such, the sterilizing effect of ozone has been proven worldwide, but the World Health Organization (WHO) reports that ozone concentration above 0.05ppm is harmful to the human body and its use should be refrained. Due to this, there is a need to develop a sterilizing device that can be safely used at home by utilizing ozone, which has excellent sterilizing power, as its use is limited at home.

This is a drawing showing the state in which the sealing stopper is installed. Referring to FIG. 4, the state in which the safety sterilization device is installed in the multipurpose box will be described.

In detail, the sterilization box using a safety sterilization device represents an embodiment in which the safety sterilization device 1000 is mounted on the upper surface of the multi-purpose box 10, and clothing or objects provided in the multi-purpose box 10 are sterilized. In this way, the safety sterilization device 1000 is installed to be detachable in the multi-purpose box 10, and after sterilizing the sterilizer discharge space 1 inside the multi-purpose box 10, the safety sterilization device 1000 is separated by the user. In this state, it can be installed in another multi-purpose box (10) and can be used repeatedly in multiple multi-purpose boxes.

Since the safety sterilization device 1000 has the same configuration as described in FIGS. 1 to 3, detailed description will be omitted.

The multipurpose box 10 is made in the shape of a box, and a safety sterilization device 1000 is installed on the upper surface so that it can be separated from the main body 100, and is located at a position corresponding to the disinfectant discharge port 120 of the main body 100. A disinfectant inlet (12a) of an open shape is provided. At this time, the multi-purpose box 10 supplies the disinfectant generated from the disinfectant generating unit 200 to the disinfectant discharge space 1 of the multi-purpose box 10 through the disinfectant inlet 12a, so that the clothes or items stored inside are uniformly distributed. It is thoroughly sterilized.

In detail, the multipurpose box 10 includes a storage container 11 with an open upper surface and a disinfectant discharge space 1 formed therein, and a storage container 11 that is detachably attached to the upper surface of the storage container 11 and has a safety sterilization device 1000 at the top. If not installed, an airtight stopper (12b) is mounted on the disinfectant inlet (12a) and may include a container cover (12) to seal the storage container (11). At this time, the multipurpose box 10 can be used for its original storage purpose by sealing the sterilizing agent inlet 12a with the airtight stopper 12b by the user after sterilization is completed.

Additionally, the multipurpose box 10 is preferably made of a transparent material so that the user can check what items are stored there. In addition, the multi-purpose box (10) may be equipped with a coupler or connector so that the safety sterilization device (1000) can be installed on the upper surface, and has a structure that is detachable after installation, so that it can be used as a single safety sterilization device (1000) for multiple purposes.

Figure 5 is a configuration diagram of a safety sterilization device according to an embodiment of the present invention, and Figure 6 is a flow chart showing the operating sequence of the safety sterilization device according to the present invention. With reference to FIGS. 5 and 6, a control method of a safety sterilization device according to an embodiment of the present invention will be described.

First, there is a device installation step in which the safety sterilization device 1000 is installed in the space to be sterilized by the user. At this time, the space where the safety sterilization device 1000 is installed is the disinfectant discharge space 1 where the disinfectant is sprayed, and may be an indoor space or an internal space of a multi-purpose box such as a living box. And this is the volume input step in which the volume of the disinfectant discharge space is input through the input unit 300. At this time, the signal is input by the user to the input unit 300 n times (n=1, 2, 3...n) as many times as the number of inputs matches the volume of the disinfectant discharge space.

For example, if the multi-purpose box is 20L, the signal is input once, if the multi-purpose box is 50L, the signal is input twice, if it is a clothing case, the signal is input 3 times, and if it is inside a car or indoor space, the signal is input 4 times. And if it is input by the user more than 5 times, it is reset to the number of signals corresponding to n-4 times and executed again. Next is the time setting step in which the disinfectant injection time is automatically set according to the n number of signal inputs input to the input unit 300. At this time, in the time setting step, the disinfectant injection time is set to T1 corresponding to the 20L multipurpose box, T2 corresponding to the 50L multipurpose box, T3 corresponding to the clothing case, and T4 corresponding to the booster.

Afterwards, in the time setting step, the operating time set among T1, T2, T3, and T4 is output to the display unit 400. Subsequently, a sterilizing agent is generated inside the main body 100 by the corona discharge principle in the sterilizing agent generating unit 200 during the sterilizing agent spraying time set through the time setting step, and is sprayed into the sterilizing agent discharge space 1 to perform sterilization. It's a step. At this time, the disinfectant generated by the disinfectant generation unit 200 through the sterilization performance step is sprayed until the operation time displayed on the display unit 400 becomes '0'.

Next, if the ozone concentration value in the disinfectant discharge space (1) measured through the ozone meter (500) is below the safe coefficient, it is a safety confirmation step performed to maintain the operating state of the disinfectant generating unit (200). On the other hand, when the ozone concentration value in the disinfectant discharge space (1) measured through the ozone meter (500) exceeds the safe coefficient, the power is cut off and the operating state of the disinfectant generating unit (200) is stopped. Afterwards, the operation time of the display unit 400 is changed to '0' and when the operation is completed, the power to the safety sterilization device is turned off and the operation is automatically terminated.

A person skilled in the art to which the present invention pertains will understand that the present invention can be implemented in a modified form without departing from the essential characteristics of the present invention. Therefore, the disclosed embodiments should be considered from an illustrative rather than a restrictive perspective.
