To solve this problem, system windows have been developed.
일반적으로 시스템 창호는 외부의 빛을 실내로 유입시키는 역할과 실내 공기를 적절히 환기시키는 역할을 수행하며, 닫힘 상태에서는 실내와 실외의 열 흐름을 차단시켜서 실내의 냉, 난방 효과를 유지하는 역할을 수행한다.In general, the system windows serve to inject external light into the room and to properly ventilate the indoor air.In the closed state, it blocks the flow of heat from the inside and outside to maintain the cooling and heating effect of the room. do.
이러한 시스템 창호에서 실내를 환기시키고자 할 때는 창문을 열어서 자연 환기시키거나 또는, 별도의 강제환기장치에 의해 강제환기시키는 방법을 취하고 있는데, 일반 가정에서는 주로 전자의 방법이 이용되고 있다. In order to ventilate the room in such a system window, a window is naturally ventilated by opening a window or forcedly ventilated by a separate forced ventilator. In general, the former method is mainly used.
그러나, 창문을 열어 실내를 환기시키는 방법은 실외공기에 포함된 먼지나 각종 해충, 꽃가루 등의 오염물이 유입되는 문제점이 있으며, 비가 오거나 안개가 낀 날에는 창문을 개방하지 못해 바람직하지 않다. 이에 따라, 종래에는 창짝프레임의 일부분에 개폐가 가능한 환기장치를 설치하여 환기 및 단열이 가능하도록 하고 있다. However, the method of ventilating the room by opening a window has a problem that contaminants such as dust, various pests, pollen, etc. contained in outdoor air are introduced, and it is not preferable because the window cannot be opened on a rainy or foggy day. Accordingly, in the related art, a ventilation device that can be opened and closed is installed on a part of the window frame to allow ventilation and heat insulation.
또한, 환기장치를 사용하지 않고 공기청정기 등을 사용하는 경우, 외부로부터의 신선한 공기가 유입되는 것을 배제한 것이고, 충분한 환기가 이루어지지 못하는 문제가 있다.In addition, when using an air cleaner or the like without using a ventilation device, the fresh air from the outside is excluded, there is a problem that sufficient ventilation is not achieved.
일반적인 시스템 창호에 구비된 환기장치 또는 필터(또는 방충망)는 입자가 큰 미세먼지, 화분, 곤충 등을 차단하는 것은 가능하나, PM2.5 이하의 초미세먼지, 병원균, 냄새 등을 차단하지 못하였다.Ventilation devices or filters (or insect screens) provided in general system windows can block large particles, pollen, insects, etc., but they cannot block ultrafine dust below PM2.5, pathogens, odors, etc. .
PM2.5 이하의 초미세먼지를 차단하는 것이 가능한 자연 환기형 멤브레인은 기공 크기가 감소함에 따라 자연 환기방식으로는 외부 공기가 실내로 유입되는 공기의 환기량이 적어서 환기의 실효성이 떨어지는 문제가 있다.The natural ventilation type membrane capable of blocking ultrafine dust below PM2.5 has a problem in that the effectiveness of ventilation is lowered due to the small amount of ventilation of outside air introduced into the room by the natural ventilation method as the pore size decreases.
종래에 내부에 실내창과 실외창이 장착되는 프레임과, 프레임의 상하 또는 좌우면에 서로 대향되도록 설치되는 흡배기장치와, 흡배기장치와 프레임 사이에 각각 설치되는 송풍장치를 포함하는 다기능 창호 시스템이 제안되어 있다.Conventionally, a multifunctional window system has been proposed including a frame on which an indoor window and an outdoor window are mounted, an intake and exhaust device installed to face each other on the upper and lower sides, and the left and right sides of the frame, and a blower installed between the intake and the frame. .
그러나, 상기 흡배기장치에는 동력에 의해 흡배기공의 유로를 개폐하는 개폐수단을 구비하고 있으나, 좁은 유로 상에 설치된 필터를 통과하면서 외부 공기의 실내 유입 유로를 설정하는 개폐수단을 제어하도록 다수의 모터를 설치해야 하며, 좁은 유로상에 필터를 설치함에 따라 충분한 크기의 필터를 사용하지 못하는 문제가 있다. 그 결과, 충분한 양의 신선한 공기를 실내로 공급하기 위해서는 작은 면적의 필터를 사용하는 데 따른 송풍팬 모터의 가동시간이 길어지고 가동주기가 짧아져서 유지비용이 증가하는 문제가 발생할 수 있다.However, although the intake and exhaust device has an opening and closing means for opening and closing the flow path of the intake and exhaust pores by power, a plurality of motors are controlled to control the opening and closing means for setting the indoor inflow flow path of the outside air while passing through the filter installed on the narrow flow path. Must be installed, there is a problem that can not use a filter of sufficient size by installing the filter on a narrow passage. As a result, in order to supply a sufficient amount of fresh air into the room, a problem may occur in that the operation time of the blower fan motor is increased due to the use of a small area filter and the operation cycle is shortened, thereby increasing the maintenance cost.
또한, 다기능 창호 시스템에서는 필터의 가동에 따라 흡착되는 먼지나 이물질을 자동으로 청소할 수 없어 수동으로 작업하여야 하는 문제가 있다.In addition, in the multi-functional window system, there is a problem in that dust or foreign matter adsorbed in accordance with the operation of the filter cannot be cleaned automatically, so that the work must be performed manually.

이하에 도 7a 및 도 7b를 참고하여 솔레노이드 액튜에이터 구동방식의 제1 및 제2 셔터장치를 설명한다.Hereinafter, the first and second shutter apparatuses of the solenoid actuator driving method will be described with reference to FIGS. 7A and 7B.
제1 및 제2 셔터장치(160)는 각각 상하방향으로 승강 및 하강 가능하게 설치되고 상부 또는 하부에 공간부(162)를 갖는 가동 셔터(161)와, 상기 가동 셔터(161)의 일단에 연결된 플런저(165)를 상승 및 하강시키는 솔레노이드(164)를 포함하고 있다.The first and second shutter devices 160 are provided to be movable up and down in the vertical direction, respectively, and are connected to a movable shutter 161 having a space 162 at an upper portion or a lower portion thereof, and connected to one end of the movable shutter 161. And a solenoid 164 that raises and lowers the plunger 165.
상기 가동 셔터(161)는 솔레노이드(164)에 의해 직선 구동될 때 상하방향으로 승강 및 하강이 안정되게 이루어지도록 상측 및 하측에 각각 2개씩의 가이드핀(163)이 결합되어 가이드되고 있다. When the movable shutter 161 is linearly driven by the solenoid 164, two guide pins 163 are guided to each of the upper and lower sides so that the lifting and lowering of the movable shutter 161 is made stable.
솔레노이드 액튜에이터 구동방식인 경우, 필터 세정 모드일 때 솔레노이드(164)에 제어부(171)로부터 구동신호가 인가되면 내부 코일에 전류가 흐르면서 자기장이 발생되어 플런저(165)를 솔레노이드(164) 내부로 수축시키게 된다. 그 결과 도 5 및 도 7a와 같이 가동 셔터(161)가 하강하여 유입구(135)를 차단한다.In the case of the solenoid actuator driving method, when a driving signal is applied from the control unit 171 to the solenoid 164 in the filter cleaning mode, a magnetic field is generated while current flows in the internal coil to contract the plunger 165 into the solenoid 164. do.

Heat exchange is carried out when staying in the residence space 136.
상기 커버판(120)에 설치되는 히터(121)는 예를 들어, 비저항이 1이상인 금속 박막 또는 비정질 리본을 슬리팅하여 얻어지는 비정질 스트립 등으로 이루어진 스트립형 면상 발열체를 직렬 및/또는 병렬 접속하여 구성된 히터 조립체 또는 열선을 사용할 수 있다. 상기 스트립형 면상 발열체는 예를 들어, Fe계 비정질 리본 또는 FeCrAl로 이루어진 것을 사용할 수 있다.The heater 121 installed on the cover plate 120 is configured by connecting, in series and / or parallel, a strip-like planar heating element made of, for example, an amorphous strip obtained by slitting a metal thin film or an amorphous ribbon having a specific resistance of 1 or more. A heater assembly or hot wire can be used. The strip-shaped planar heating element may be formed of, for example, Fe-based amorphous ribbon or FeCrAl.
이하에 본 발명에 따른 스마트 창호의 동작을 도 9를 참고하여 설명한다.Hereinafter, the operation of the smart window and door according to the present invention will be described with reference to FIG.
본 발명에 따른 스마트 창호는 제1프레임(131)의 전면에 설치된 전원 스위치(147)를 턴-온시키는 것으로 제어 시스템(170)을 기동시켜서 동작을 개시하게 할 수 있다.The smart window according to the present invention may turn on the power switch 147 installed in the front of the first frame 131 to start the control system 170 to start the operation.
또는 리모콘(180)을 이용하여 제어 시스템을 구동시키는 파워공급신호를 무선으로 전송하여 제어 시스템(170)을 기동시켜서 동작을 개시하게 할 수 있다.Alternatively, the remote controller 180 may wirelessly transmit a power supply signal for driving the control system to start the control system 170 to start an operation.
이 경우, 제어부(171)는 우선 빛감지센서(174)를 통하여 실내의 조도를 검출한다(S11). 검출된 실내의 조도값이 설정된 조도 기준값을 초과하는 경우, 주간 또는 실내에 조명이 점등된 상태인 것으로 판단한다(S12).In this case, the control unit 171 first detects the illuminance of the room through the light sensor 174 (S11). When the detected illuminance value of the room exceeds the set illuminance reference value, it is determined that illumination is turned on in the daytime or in the room (S12).
실내의 조도값을 검출하여 야간 상태를 판단하는 것은 사용자가 실내에 없는 경우, 즉, 침실에서 잠을 자는 경우나 외출 또는 출장간 경우에는 유지비용을 최소화하기 위하여 스마트 창호의 작동을 정지시키기 위함이다.The nighttime condition is determined by detecting the illuminance value of the room in order to stop the operation of the smart window in order to minimize the maintenance cost when the user is not indoors, that is, when sleeping in the bedroom or when going out or traveling. .
또한, 사용자가 실내에서 활동하는 기간에 실내의 오염 여부를 판단하여 외부로부터의 신선한 공기를 실내로 공급함에 의해 유지비용을 최소화하면서도 효율성을 도모하기 위한 것이다.In addition, the user is to determine whether the indoor pollution during the period of activity indoors to supply the fresh air from the outside to minimize the maintenance cost while achieving efficiency.
상기 단계(S12) 판단결과 주간이거나 또는 실내에 조명이 점등된 상태인 경우, 오염도 측정센서(172)를 통하여 실내의 오염도를 측정한다(S13).As a result of the determination in step S12, when the lighting is in the daytime or in the room, the pollution degree of the room is measured through the pollution degree sensor 172 (S13).
측정된 오염도가 기준값을 초과하는 지를 판단하여(S14), 만약 측정된 오염도가 오염도 기준값을 초과하는 경우, 제어부(171)는 제1 및 제2 송풍기(140a,140b)를 작동하도록 모터(42)에 구동신호를 인가한다(S15).It is determined whether the measured pollution degree exceeds the reference value (S14), and if the measured pollution degree exceeds the pollution degree reference value, the controller 171 operates the motor 42 to operate the first and second blowers 140a and 140b. The drive signal is applied to the drive (S15).
이에 따라 모터(42)가 구동되면, 도 4 및 도 6a와 같이 송풍팬(146)이 회전되면서 수용공간(137a,137b)의 공기가 유출구(135)를 통하여 실내로 배출되며, 그 결과 수용공간(137a,137b)에 부압 또는 흡인력이 발생하면서 상기 부압 또는 흡입력은 상기 수용공간(137a,137b)과 연통된 유입구(134)를 통해 체류공간(136) 측으로 제공되고, 상기 차단부재(110) 주위의 외기가 흡입력에 의해 차단부재(110)를 통과하여 미세먼지가 제거되면서 상기 체류공간(136) 측으로 유입된다. 이후, 상기 체류공간(136)으로 유입된 외기는 유입구(134), 수용공간(137a,137b) 및 유출구(135)를 순차적으로 통과하여 실내 측으로 공급될 수 있다.Accordingly, when the motor 42 is driven, as the blower fan 146 is rotated as shown in FIGS. 4 and 6A, the air in the accommodation spaces 137a and 137b is discharged into the room through the outlet 135, and as a result, the accommodation space. While the negative pressure or suction force is generated at 137a and 137b, the negative pressure or suction force is provided to the residence space 136 through the inlet 134 communicating with the receiving spaces 137a and 137b, and around the blocking member 110. The outside air flows through the blocking member 110 by the suction force and is introduced into the staying space 136 while the fine dust is removed. Thereafter, the outside air introduced into the staying space 136 may be sequentially supplied through the inlet 134, the accommodation spaces 137a and 137b, and the outlet 135 to be supplied to the indoor side.
이러한 제1 및 제2 송풍기(140a,140b)의 작동이 이루어지면, 제어부(171)는 외기온도센서(175) 및 실내온도센서(176)를 통하여 외기와 실내의 온도를 측정하며(S16), 우선 측정된 외기온도가 사용자가 설정한 설정온도보다 낮은 지를 판단하여(S17), 만약 외기온도가 사용자가 설정한 설정온도보다 낮은 경우 실내로 유입되는 차가운 외기의 열교환을 위해 히터(121)를 가동한다(S18).When the operation of the first and second blowers 140a and 140b is made, the controller 171 measures the temperature of the outside and the room through the outside temperature sensor 175 and the room temperature sensor 176 (S16), First, it is determined whether the measured outside temperature is lower than the set temperature set by the user (S17). If the outside temperature is lower than the set temperature set by the user, the heater 121 is operated for heat exchange of cold outside air flowing into the room. (S18).
또한, 상기 히터(121)의 가동은 외기온도와 실내온도를 비교하여 차이값이 미리 설정한 기준값보다 큰 경우에 진행하도록 설정할 수도 있다.In addition, the operation of the heater 121 may be set to proceed when the difference value is greater than the preset reference value by comparing the outdoor temperature and the room temperature.
더욱이, 본 발명에서는 겨울철에 외부기온에 따라 커버판(120)에 결로현상이 발생하는 것을 고려하여, 제1 및 제2 송풍기(140a,140b)의 작동 여부와 무관하게 외기온도센서(175)와 실내온도센서(176)로부터 측정된 외기와 실내의 온도를 검출한 후, 이를 신호처리하여 결로현상 여부를 판단하고 결로현상을 해소하기 위한 목적으로 히터(121)를 가동하는 것도 가능하다.Furthermore, in the present invention, in consideration of the occurrence of condensation on the cover plate 120 according to the external temperature in winter, regardless of the operation of the first and second blowers (140a, 140b) and the outside air temperature sensor (175) After detecting the temperature of the outside air and the room measured by the room temperature sensor 176, it is also possible to process the signal to determine whether the condensation phenomenon and to operate the heater 121 for the purpose of eliminating the condensation phenomenon.
한편, 상기 단계(S12)에서 검출된 실내의 조도값이 설정된 조도 기준값을 초과하지 않는 경우, 야간 또는 실내에 조명이 소등된 상태인 것으로 판단한다.On the other hand, if the illuminance value of the room detected in the step (S12) does not exceed the set illuminance reference value, it is determined that the lighting is turned off at night or indoors.
제어부(171)는 주간에 제1 및 제2 송풍기(140a,140b)를 작동할 때, 제1 및 제2 차단부재(111,112)의 내측인 체류공간(136)에 부압이 걸리는 것을 부압 측정센서(173)를 사용하여 측정하고(S21), 측정된 부압값을 메모리장치에 저장한다.The control unit 171 is a negative pressure measuring sensor that is applied when the negative pressure is applied to the retention space 136 inside the first and second blocking members 111 and 112 when the first and second blowers 140a and 140b are operated during the day. 173) and store the measured negative pressure value in the memory device.
메모리장치에 저장된 부압값이 미리 설정된 기준값과 비교하여(S22), 만약 측정된 부압이 기준값보다 더 큰 경우 제2차단부재(112)의 미세 기공에 먼지, 이물질, 화분 등이 흡착되어 축적되면서 필터의 기공도가 낮아진 것으로 판단하여 필터 세정 모드를 실시한다(S23).When the negative pressure value stored in the memory device is compared with a preset reference value (S22), if the measured negative pressure is larger than the reference value, dust, foreign matter, pollen, etc. accumulate and accumulate in the micropores of the second blocking member 112 and filter the filter. It is determined that the porosity of the filter is reduced to perform the filter cleaning mode (S23).
이 경우, 제어부(171)는 제1 및 제2 셔터장치(150)의 구동모터(153)에 구동신호를 인가하여 피니언(152)을 반시계방향으로 회전시켜서 랙(151)을 하강시킴에 의해 유입구(135)의 일부만 남기고 대부분을 차단하도록 설정한다. 랙(151)으로 유입구(135)의 일부를 차단하지 않는 것은 제1 및 제2 송풍기(140a,140b)를 작동할 때, 수용공간(137a,137b)과 체류공간(136)에 부압이 걸리는 것을 피하기 위한 것이다.In this case, the controller 171 applies a drive signal to the drive motors 153 of the first and second shutter devices 150 to rotate the pinion 152 counterclockwise to lower the rack 151. Only part of the inlet 135 is left and set to block most. Not blocking part of the inlet 135 with the rack 151 indicates that underpressure is applied to the receiving spaces 137a and 137b and the staying space 136 when the first and second blowers 140a and 140b are operated. It is to avoid.
이 상태에서, 제1 및 제2 송풍기(140a,140b)를 작동시키면, 도 5 및 도 6b와 같이 실내로부터 유입구(135)의 일부를 통하여 수용공간(137a,137b)과 체류공간(136)을 거쳐 제1 및 제2 차단부재(111,112)에 가압된 공기가 인가된다.In this state, when the first and second blowers 140a and 140b are operated, the accommodation spaces 137a and 137b and the staying space 136 are opened through a part of the inlet 135 from the inside as shown in FIGS. 5 and 6b. Pressurized air is applied to the first and second blocking members 111 and 112.
특히, 제1 및 제2 송풍기(140a,140b)를 작동시킬 때, 가변적 속도로 구동하여 리듬 기류를 형성하거나, 간헐 구동이 이루어지도록 펄스형 구동전압을 인가함에 의해 충격파 기류를 발생하여 제1 및 제2 차단부재(111,112)에 충격을 인가하도록 구동하는 것이 제1 및 제2 차단부재(111,112)의 세정 효율을 높일 수 있다.In particular, when the first and second blowers 140a and 140b are operated, a shock wave airflow is generated by driving at a variable speed to form a rhythm airflow or by applying a pulsed driving voltage so that intermittent driving is performed. Driving to apply an impact to the second blocking members 111 and 112 may increase the cleaning efficiency of the first and second blocking members 111 and 112.
제1 및 제2 차단부재(111,112)에 대한 필터 세정 모드의 실행은 필터의 미세 기공에 먼지 등이 흡착되어 축적되는 것을 미연에 차단하도록 관리하는 것이 신선한 외기를 실내로 도입할 수 있다는 점에서 바람직하다. 따라서, 매일 야간마다 미리 설정된 시간동안 필터 세정 모드를 실행할 수 있다.Execution of the filter cleaning mode for the first and second blocking members 111 and 112 is preferable in that it can introduce fresh outside air into the room by managing to prevent the adsorption and accumulation of dust and the like in the fine pores of the filter in advance. Do. Therefore, the filter cleaning mode can be executed for a preset time every night.
그러나, 제1 및 제2 차단부재(111,112)에 구비된 나노섬유 웹으로 이루어진 멤브레인 필터는 사용시간이 증가하면 점차적으로 필터의 미세 기공에 먼지 등이 축적되어 자동 세정이 어려운 경우에 도달할 수 있다.However, the membrane filter made of the nanofiber web provided in the first and second blocking members 111 and 112 may reach a case where it is difficult to automatically clean the dust due to accumulation of fine pores of the filter as the use time increases. .
본 발명에서는 이러한 점을 고려하여 필터 세정 모드를 실행한 횟수 또는 필터를 사용한 기간을 고려하여 미리 설정한 기준값을 초과하는 경우, 알람장치(171)를 통하여 사용자에게 알린다(S25).In the present invention, the user is notified through the alarm device 171 when the preset reference value is exceeded in consideration of the number of times the filter cleaning mode has been executed or the period of time the filter is used in consideration of this point (S25).
상기한 알람장치(171)는 발광다이오드(LED)를 사용하여 점멸 구동하거나, 경보음을 발생하게 할 수 있다. 이 경우, 사용자는 적절한 세정제를 사용하여 제2 차단부재(111,112)의 미세 기공에 축적된 먼지 등을 제거한 후 재사용하거나, 새로운 필터로 교체하여 사용할 수 있다.The alarm device 171 may be driven by using a light emitting diode (LED) to blink or generate an alarm sound. In this case, the user may remove dust accumulated in the micropores of the second blocking members 111 and 112 by using an appropriate cleaning agent and reuse it, or replace it with a new filter.
한편, 상기 스마트 창호에서는 제어부(171)가 빛감지센서(174)로부터 검출된 실내의 조도값을 매일 미리 설정된 야간의 특정시간에 판단하면 사용자가 장기간 집을 비우는 것을 판단할 수 있으며, 제어 시스템의 동작을 휴면 모드로 설정하고, 작동을 정지시킬 수 있다. 이 경우, 사용자가 예를 들어, 리모콘(180)의 리셋 버튼을 누르면, 시스템 기동이 이루어지도록 설정할 수 있다.On the other hand, in the smart window, if the control unit 171 determines the illuminance value of the room detected by the light sensor 174 at a specific time of the night set in advance every day, it can determine that the user is emptying the house for a long time, the operation of the control system Can be set to sleep mode and disabled. In this case, for example, when the user presses the reset button of the remote controller 180, the system can be set up to be activated.
상기한 바와 같이, 본 발명의 실시예 설명에서는 송풍기(140a,140b)가 배치구멍(138)을 통해 지지프레임(130)과 결합되는 것으로 설명하였지만 송풍기(140)와 지지프레임(130)의 결합구조를 이에 한정하는 것은 아니며, 공지의 다양한 방식이 적용될 수 있으며, 설계 구조에 따라 적절하게 변경될 수 있다. 다만, 상기 송풍기(140a,140b)가 수용공간(137a,137b) 측에 배치되어 구동시 흡입력을 제공할 수 있는 형태라면 무방하다.As described above, in the description of the embodiment of the present invention, the blowers 140a and 140b are described as being coupled to the support frame 130 through the placement holes 138, but the coupling structure of the blower 140 and the support frame 130 is described. It is not limited to this, various known methods can be applied, it may be appropriately changed according to the design structure. However, the blowers 140a and 140b may be disposed on the receiving spaces 137a and 137b so as to provide suction power during driving.
더불어, 강제 대류 방식으로 모터(142)의 구동을 통해 회전하는 송풍팬(146)을 예시하였지만, 이에 한정하는 것은 아니며 공지의 공기흡입기(미도시)를 이용한 석션 방식이 적용될 수도 있다.In addition, although the blowing fan 146 rotates through the driving of the motor 142 by a forced convection method, but not limited thereto, a suction method using a known air inhaler (not shown) may be applied.
상기한 실시예 설명에서는 유지비 절감의 목적으로 실내의 조도가 조도 기준값 이상이고 실내 공기의 오염도가 기준값을 초과하는 경우에 송풍기(140a,140b)를 구동하여 외기를 실내로 흡인하는 동작을 수행하도록 하고 있으나, 실내의 조도가 조도 기준값 이하인 경우, 즉 야간에도 실내 공기의 오염도가 기준값을 초과하는 경우에는 송풍기(140a,140b)를 구동하여 외기를 실내로 흡인하게 할 수 있다.In the above description of the embodiment, for the purpose of reducing the maintenance cost, when the illuminance of the room is equal to or greater than the illuminance reference value and the pollution degree of the indoor air exceeds the reference value, the air blowers 140a and 140b are driven to suck the outside air into the room. However, when the indoor illuminance is below the illuminance reference value, that is, when the pollution degree of the indoor air exceeds the reference value even at night, the air blowers 140a and 140b may be driven to suck the outside air into the room.

The window unit 220 may be formed as a transparent window that is fixed to the first mounting portion 212 of the frame 210 and satisfies both sunlight transmission and visibility, or an opaque window that can transmit sunlight only.
기존의 창문형 공기정화 시스템의 경우 창문 전체가 공기정화장치에 의해 막힌 형태이기 때문에 실내로 햇빛이 유입되지 못하여 실내가 어둡고 답답한 느낌을 준다. 본 실시예에 따른 스마트 창호는 프레임(210)의 일측에 윈도우 유닛(220)이 장착되어 햇빛 투과 및 시야를 확보할 수 있고, 프레임(210)의 타측에 공기정화유닛(230)이 설치되어 실외공기를 직접 정화하여 실내로 공급함으로써 공기정화와 시야 확보 두 가지를 동시에 만족시킬 수 있다. In the case of the conventional window type air purifying system, since the whole window is blocked by the air purifier, sunlight does not flow into the room, making the room dark and stuffy. In the smart window according to the present embodiment, the window unit 220 is mounted on one side of the frame 210 to ensure sunlight transmission and visibility, and the air purification unit 230 is installed on the other side of the frame 210 to be outdoors. By directly purifying air and supplying it to the room, both air purification and visibility can be satisfied at the same time.
공기정화유닛(230)은 프레임(10)의 제2장착부(214)에 고정되는 하우징(232)과, 하우징(232)의 내측에 장착되어 외부공기를 강제로 송풍시키는 송풍유닛(236)과, 하우징(232)의 전면에 외부로 노출되게 장착되어 실외공기를 정화하는 필터유닛(234)을 포함한다.

하우징(232)은 프레임(210)의 실내에 위치되는 측면에 장착되고 그 상면에는 필터유닛(234)을 통과한 공기가 실내로 유입되는 공기 공급구(242)가 형성되고, 그 전면에는 실외공기가 유입되는 공기 유입구(240)가 형성되며, 그 후면에는 커버(238)가 개폐 가능하게 장착된다. The housing 232 is mounted on a side surface of the frame 210, and an air supply port 242 is formed on the upper surface of which the air passing through the filter unit 234 flows into the room. Is introduced air inlet 240 is formed, the rear of the cover 238 is mounted to open and close.
이러한 하우징(232)은 프레임(210)의 약 1/2 정도의 공간을 차지하는 사이즈이고, 공기 유입구(240)는 하우징(232)의 전면 전체에 형성되어 공기가 통과하는 면적을 최대로 할 수 있고, 하우징(232)의 전면에는 필터유닛(234)이 이탈되는 것을 방지하기 위한 지지해주는 지지대(248)가 형성된다. The housing 232 is a size occupying about half the space of the frame 210, the air inlet 240 is formed on the entire front of the housing 232 can maximize the area where the air passes through On the front surface of the housing 232, a support 248 is formed to support the filter unit 234 from being separated.
하우징(232)의 내부에는 송풍유닛(236)이 장착되는 송풍유닛 수납부(260)와, 필터유닛(234)이 장착되는 필터유닛 수납부(262)가 형성되고, 하우징(232)의 하면에는 필터유닛(234)이 인출 및 인입되는 필터 출입부(264)가 형성된다. The air blowing unit accommodating part 260 to which the air blowing unit 236 is mounted, and the filter unit accommodating part 262 to which the filter unit 234 is mounted, are formed in the housing 232. The filter entrance 264 through which the filter unit 234 is drawn out and drawn in is formed.
필터유닛(234)은 필터 출입부(264)로 인입하면 필터유닛 수납부(262)에 장착된다. 따라서, 필터유닛(234)을 교체할 경우 필터유닛(234)을 필터 출입부(264)로 인출하면 되므로 필터 교체작업이 쉽게 이루어질 수 있다.

다공성 나노 웹(253)은 전기 방사방법으로 제조되므로 고분자 물질의 방사량에 따라 두께가 결정된다. 따라서, 다공성 나노 웹(253)의 두께를 원하는 두께로 만들기가 쉬운 장점이 있다. Since the porous nanoweb 253 is manufactured by an electrospinning method, the thickness of the porous nanoweb 253 is determined by the radiation amount of the polymer material. Therefore, there is an advantage that it is easy to make the thickness of the porous nano-web 253 to the desired thickness.
따라서, 다공성 나노 웹(253)의 두께에 따라 기공수 및 기공의 평균 사이즈가 결정되므로 PM 2.5 이하의 미세 먼지를 필터링하기 적합한 기공 평균 사이즈를 제조할 수 있다. Therefore, since the number of pores and the average size of the pores are determined according to the thickness of the porous nanoweb 253, it is possible to produce a pore average size suitable for filtering fine dust of PM 2.5 or less.

In addition, since the filter unit 234 according to the present exemplary embodiment is installed to be exposed to the outside, the porous nanoweb 253 basically has a pore size through which rainwater cannot pass. A water repellent coating layer is formed on the surface of the porous nanoweb 253 to prevent rainwater from penetrating into the porous nanoweb.
다공성 나노 웹(253)은 도 18에 도시된 바와 같이, 외부로 노출된 상태이기 때문에 다공성 나노 웹(253) 표면에 스크래치 등이 발생되는 것을 방지하기 위해 강도 보강층(258)이 적층될 수 있다.Since the porous nanoweb 253 is exposed to the outside as shown in FIG. 18, the strength reinforcing layer 258 may be stacked to prevent scratches or the like from occurring on the surface of the porous nanoweb 253.
강도 보강층(258)은 안료, 바인더 및 용매를 일정 비율로 혼합되고 다공성 나노 웹(253)의 표면에 도포된다. 강도 보강층(258)에 사용되는 안료는 검정 또는 컬러 색상의 안료를 사용하게 되는데, 안료의 사용량, 종류에 따라 다양한 색상, 톤을 구현할 수 있다. The strength reinforcing layer 258 is mixed with a pigment, a binder, and a solvent in a ratio and applied to the surface of the porous nanoweb 253. As the pigment used in the strength reinforcing layer 258, a pigment of black or color color is used, and various colors and tones may be realized according to the amount and type of pigment used.
강도 보강층(258)의 도포 방법은 그라비아 인쇄, 코팅 등을 사용할 수 있고, 다공성 나노 웹(253)를 만드는 방법과 마찬가지로 전기 방사에 의해 만드는 것도 가능하다. The method of applying the strength reinforcing layer 258 may include gravure printing, coating, or the like, and may be made by electrospinning in the same manner as the method of making the porous nanoweb 253.

즉, 다공성 나노 웹(253)은 전기 방사방법에 의해 제조되어 나노섬유(254)가 축적된 형태이므로 나노섬유 사이에 기공(256)이 형성되고, 강도 보강층(258)이 나노섬유(254)가 서로 만나는 지점에 도포되어 다공성 나노 웹(253)의 강도를 강화시키게 된다. 따라서, 외부의 충격이나 소리의 압력에 다공성 나노 웹(253)이 변형되는 것을 최소화할 수 있게 된다. That is, since the porous nanoweb 253 is manufactured by the electrospinning method and the nanofibers 254 are accumulated, pores 256 are formed between the nanofibers, and the strength reinforcing layer 258 is formed of the nanofibers 254. It is applied at the point where they meet each other to enhance the strength of the porous nano-web 253. Therefore, it is possible to minimize deformation of the porous nanoweb 253 due to external impact or sound pressure.
