The clean booth system according to the present invention largely includes a base frame 110 , a blower module 120 , an air purification module 130 , a sterilization module 140 , and a control module 150 .

The base frame 110 refers to a basic skeleton forming the target space 101 having a predetermined volume within the access space. The base frame 110 is again composed of the inner chamber door frame portion 112 , the side wall frame portion 114 , the ceiling frame portion 116 , and the floor frame portion 118 . The inner chamber door frame portion 112 and the side wall frame portion 114 are in the form of a wall structure.

The inner chamber door frame unit 112 is a structure including an inner chamber door. According to the designer's choice, the interior door may be configured in the form of a sliding door or a sliding door, which may be selected in an optimized manner in consideration of the size and location of the target space. The inner door is connected to the control module 150 and is configured to transmit and receive a control signal. The control signal includes an opening/closing signal of the inner chamber door. According to the opening/closing signal, the inner chamber door may visually provide the user with information on whether the inner chamber door can be opened, the cleaning execution mode and time, and the like, and for this purpose, a display panel (not shown) may be provided. As shown in FIG. 1 , the inner chamber door frame part 112 is formed adjacent to the inner chamber side and is formed on a side opposite to the access door side. That is, the space between the inner door and the access door is defined as the access space, and the space covered by the clean booth system according to the present invention installed inside the access space is defined as the target space. It is preferable that the entrance space and the target space are configured to almost coincide.

The side wall frame part 114 is positioned so as to be in contact with one edge of the inner chamber door frame part 112 . Referring to FIG. 4 first, a shoe rack is located on one side of the entrance space. Such a structure can be easily seen in the structure of a general household. In this case, the inner chamber door frame unit 112 is located on the side opposite to the shoe cabinet. The blowing module 120 is built in the side wall frame part 114 . The blower module 120 includes fan units 122 and 124 for blowing air and flow path members 114b and 118b connected to the fan units 122 and 124 and air holes 114a, 116a and 118a. am. Air is discharged through the air hole (114a) formed in the side wall frame portion 114 is configured to remove foreign substances attached to the user's clothes or body. Here, the air may be simple air, but may be a gas in which a functional material for sterilization is mixed. This may vary depending on the characteristics of the installation location of the clean booth system according to the present invention.

The ceiling frame unit 116 is coupled to the upper end of the inner chamber door frame unit 112 and the side wall frame unit 114 , and serves to cover the upper surface of the target space 101 . Like the side wall frame unit 114 , the ceiling frame unit 116 may also include fan units 122 and 124 separately. 124) can be communicated. The air hole 116a of the ceiling frame part 116 is configured to discharge air downward. In addition, the UV lamp unit 142 may be built in the ceiling frame unit 116 . The ultraviolet lamp unit 142 may sterilize a user located in the target space by irradiating UV (Ultraviolet Ray) toward the target space. In addition, a functional material supply unit 144 may be provided. The functional material supply unit 144 includes both a plasma ion device, a natural phytoncide spray device, and the like. Of course, the functional material supply unit 144 may be provided on one side of the side wall frame unit 114 instead of the ceiling frame unit 116 according to the designer's choice.

The bottom frame part 118 is a structure that forms the bottom surface of the target space 101 . It is preferable that the fan units 122 and 124 are simultaneously coupled to the lower ends of the inner door frame unit 112 and the side wall frame unit 114 , and the fan units 122 and 124 are located in the inner space of the bottom frame unit 118 . In order to purify the air while circulating the air discharged from the side wall frame unit 114 and the ceiling frame unit 116 , the fan unit 122 of the floor frame unit 118 is preferably a suction fan, and the dust collecting unit 132 ) by being built-in together, it is configured to collect foreign substances of the circulated air. The dust collecting unit 132 needs to periodically remove foreign substances collected by a user or an administrator. 2 , the air purification module 130 may be embedded in the floor frame part 118 , and the dust collecting part 132 may be included in the air purification module 130 . The air purification module 130 includes a replaceable filter unit 131 , and the filter unit 131 may be configured as a High Efficiency Particulate Air filter (HEPA filter).

A detailed structure of the bottom frame part 118 will be described with reference to FIG. 4 .

The floor surface of the target space 101 by the floor frame unit 118 may be divided into a 'shoe storage area' and a 'temporary interior area'. Here, the shoe storage area and the temporary inner compartment are preferably formed with a step difference, and in order to prevent foreign substances on the shoes from entering the inside, the temporary inner compartment area is configured to have a step difference by a predetermined height than the shoe storage area. . The shoe storage area is an area where users entering from outside take off their shoes and store them. Of course, the user may pick up the shoes and store them separately in the shoe cabinet. The temporary interior area is the area where the user takes off their shoes and climbs up, and means the location just before the interior space. That is, the inner room space and the temporary inner room area are divided by the inner room door. It is preferable that a foot disinfection part (not shown) is also provided in the bottom frame part 118 . This is because it is difficult for the UV irradiated from the ceiling frame part 116 to reach relatively strongly to the farthest floor. However, rather than irradiating UV with the user wearing shoes, irradiating UV with the user taking off their shoes can completely sterilize the user. . In order to irradiate UV to the user, a preset type of irradiation hole 103a is formed on the bottom surface of the temporary interior area, and an ultraviolet lamp is provided inside the irradiation hole 103a.

Referring again to FIG. 4 , a structure for sealing the target space 101 will be described. The base frame 110 is configured to close the other side except for the side where the entrance door and the shoe closet are located. The base frame 110 may be configured to seal the entire entrance space, but in order to minimize the manufacturing cost, the surface on which the entrance door and the shoe rack are located may be formed open. This is because the user frequently uses the shoe rack, and if the surface on which the shoe rack is located is sealed, it may cause inconvenience to the user. Described based on this structure, for sealing the target space 101, the position where the entrance door and the side wall frame part 114 are in contact, the position where the entrance door and the shoe rack are in contact, and the position where the inner chamber door frame part 112 and the shoe rack are in contact Sealing members 171 , 172 , 173 may be formed in each vertical direction. The sealing members (171, 172, 173) are preferably formed of a material having a predetermined elasticity.

On the other hand, a frame for sealing the target space 101 may be provided on the entrance door side as well, separately from the entrance door, and the present invention does not exclude a frame facing the inner chamber door frame unit 112 on the entrance door side. .

With reference to FIG. 3, the entire configuration of the clean booth system according to the present invention will be functionally divided and described. A description of the above-described configuration will be omitted.

The clean booth system 100 includes a blower module 120 , an air purification module 130 , a sterilization module 140 , and a control module 150 . The sterilization module 140 includes a chemical liquid storage tank 146 and a functional material supply unit 144 . The chemical storage tank 146 stores the disinfectant solution. The chemical storage tank 146 is configured to be discharged through the air holes 114a and 116a in communication with the flow path member. That is, when the air holes 114a and 116a communicate with the fan units 122 and 124, air is discharged. Instead, alternative use is possible through the same flow path member.

When the chemical solution spraying mode in which the disinfectant solution is sprayed ends, the fan units 122 and 124 are operated for a predetermined time to drain the disinfectant solution remaining in the flow path member to dry the disinfectant solution in the flow path member. Through the drain using the fan units 122 and 124, the disinfectant solution remains in the flow path member to prevent contamination, and at the same time, relatively weakly provide the disinfectant solution back to the target space 101, thereby sterilizing the target space. It has the effect of further strengthening the state.

The control module 150 is configured to control all the operations of the blowing module 120 , the air purification module 130 , and the sterilization module 140 . In addition, the control module 150 is configured to interwork with external equipment.

The control module 150 is configured to receive weather information and the like from the public weather data server 210 . Weather information includes both fine dust information and temperature and humidity information. Based on this information, the output of the fan units 122 and 124 , the operation of the air purification module 130 , and the operation of the sterilization module 140 can all be controlled. For example, on a day when the fine dust concentration is very high, the output and output time of the fan units 122 and 124 may be further increased. In addition, the control module 150 may be configured to interwork with the user information database 220 . The user information database 220 may pre-store each user's gender information, body information, and the like. Each user has a different height, weight, etc., and may be set to perform a stronger cleaning operation for a user who goes out frequently or has a long outing time.

To this end, user identification is required, and it may be configured to identify the user through a wireless connection with the user terminal 230 . As for the wireless connection method, a short-range communication method may be applied. In this case, the short-distance communication method is Wi-Fi (Wireless-Fidelity), Bluetooth Low Energy (BLE), RFID (Radio Frequency Identification), infrared communication (IrDA, Infrared Data Association), UWB (Ultra-Wideband), and may be configured to use at least one of ZigBee technologies. In addition, wireless communication is at least one of code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), orthogonal frequency division multiple access (OFDMA), and single carrier frequency division multiple access (SCFDMA) technologies. It may be configured to use one. In this case, the user terminal 230 may be formed of a smart phone or a smart tablet possessed by the user, and it is specified in advance that it is also possible through a separate application. Meanwhile, in addition to the short-range communication method, a wireless recognition method may be applied. At this time, radio frequency identification (RFID) refers to a recognition system that reads stored data such as tags, labels, and cards with semiconductor chips in a non-contact manner using radio frequency. do.

Or, for example, the control module 150 may adjust the holding time of the chemical liquid injection mode according to the user. For example, the control module 150 may identify a user by receiving identification information through the user terminal 230 , and may display outing time information corresponding to the identified user among user information stored in the user information database 220 . can be derived, and the maintenance time of the chemical liquid injection mode can be determined based on the outing time information. To this end, the user information database 220 may store the user's access information for each user, and may store it by including it in the user information. Here, when the outing time according to the outing time information exceeds the threshold time, the maintenance time of the chemical liquid injection mode may be determined as a preset maximum time, and when the outing time according to the outing time information is less than or equal to the threshold time, The holding time may be determined in proportion to the outing time.

The user's access information may be determined by receiving identification information through the user terminal 230 , and for this purpose, the control module 150 receives identification information through the user terminal 230 whenever the user enters and leaves the room. Also, when the identification information is received from the direction of the room, it is determined that the user is leaving the room, and the received time may be stored as the checkout time. In addition, when the identification information is received from the outside, it is determined that the user enters the room, and the received time may be stored as the room time. Alternatively, information indicating that the user enters the room and identification information may be transmitted together to the control module 150 through the user terminal 230 , and information indicating that the user is leaving the room and identification information may be transmitted together to the control module 150 through the user terminal 230 . can also be forwarded. Alternatively, the clean booth may mount a camera device on the inside and the outside, respectively, and after acquiring an image including the user's face, the user may be specified or identified from the image. That is, when the user is identified from the image acquired from the camera device located inside, it is determined that the user is leaving, and the departure time can be determined. When the user is identified from the image acquired from the camera device located outside, the user enters You can decide the check-in time. To this end, a face recognition algorithm may be used, and since the face recognition algorithm is a conventional technology, a detailed description thereof will be omitted.

In addition, the control module 150 controls the opening/closing operation of the inner chamber door, and when an external user enters the target space and the air shower mode or chemical liquid injection mode is performed, the inner chamber door is forcibly closed, and the user located in the inner chamber It is configured to automatically open the inner chamber door when it advances to the entrance space. That is, the control module 150 performs the opening/closing control of the inner chamber differently according to the user's entry direction.

A method using the clean booth system according to the present invention will be described with reference to FIG. 6 . The method includes steps S110 to S130.

Step S110 is a step in which the user enters the target space, and the control module recognizes that the user is located in the target space, and the interior door is forcibly closed, thereby blocking the target space from the outside.

Step (S120) is a step in which the air shower mode is performed, by discharging air in the horizontal direction to the user through the air hole of the side wall frame part, and by discharging the air in the vertical direction to the user through the air hole of the ceiling frame part, This is the first step to remove foreign substances from the user.

Step S130 is a step in which the chemical liquid injection mode is performed, and the disinfectant liquid is provided from the chemical liquid storage tank and is sprayed through the air hole.

In this case, the step 130 further includes a step (S131) of irradiating ultraviolet rays to the user through the ultraviolet lamp unit provided in the ceiling frame unit. Here, the chemical liquid injection mode and the ultraviolet irradiation mode may be performed simultaneously without being distinguished before and after.

In addition, after the step (S130), it may further include a step (S140). Step S140 is a step in which the inner chamber door is opened after a preset time has elapsed, and the functional material supply unit is activated until the inner chamber door is opened. After the sterilization operation is completed, it performs a function of providing a feeling of refreshment or comfort to the user.

Although shown and described with respect to specific embodiments of the present invention, it is within the art that the present invention can be variously improved and changed without departing from the spirit of the present invention provided by the following claims. It will be obvious to those of ordinary skill in the art.
