본 고안은 공기조화기의 풍량조절장치에 관하여 특히 냉방용 공기조화기 또는 냉난방 공기조화기의 냉방운전중 약풍 운전상태에서 강품운전 상태로의 전환시 약풍운전중 증발기 표면에 부착되어 있던 물방울이 냉풍과 함께 비산 분출되는 것을 방지토록 한 공기조화기의 풍량조절장치에 관한 것이다.The present invention relates to the air volume control device of the air conditioner, in particular, that the water droplets attached to the surface of the evaporator during the low wind operation during the switching from the low wind operation state to the strong air operation state during the cooling operation of the cooling air conditioner or air conditioning air conditioner The present invention relates to an air conditioner of an air conditioner, which is to prevent scattering of air.
일반적으로 공기조화기는 제 1 도에 도시한 바와같이 본체(1)내에 설치된 송풍기(2)로써 필터(3)가 설치된 흡입구(4)로 부터 흡입된 공기를 냉각사이클의 일부를 구성하는 증발기(5)에 접촉시키면서 냉각하여 풍량조절그릴(6)이 설치된 토출구(7)를 통해 냉풍이 실내로 토출되도록 하여 냉방토록 되어 있다.In general, the air conditioner is a blower 2 installed in the main body 1, as shown in FIG. Cooling is discharged to the room through the discharge port 7 provided with the air volume control grill 6 is cooled to contact the air).
그런데 실내조건이나 필요에 따라서는 토출구(7)에서 토출되는 냉풍의 량을 강. 약으로 조절하여 최적한 냉방을 기하는 것이 요구된다.By the way, the amount of cold air discharged from the discharge port 7 is strong depending on indoor conditions and necessity. Adjusting with medicine is required to achieve optimal cooling.
따라서 종래 공기조화기에서는 제 2 도와 같이, 상기 송풍기(2)를 전원공급단(9) (10)에 전기적으로 연결함에 있어서, 접점(c)이 약풍용단자(a) 또는 강풍용단자(b)에 선택적으로 접촉되는 풍량절환스위치(8)를 통해 연결하여 풍량절환스위치(8)의 접점(c)을 약풍용단자(a) 또는 강풍용단자(b)에 선택적으로 접촉시킴으로써 약풍 운전상태 또는 강풍운전상태로 절환시키도록 되어 있다.Therefore, in the conventional air conditioner, as shown in FIG. 2, in the electrical connection of the blower 2 to the power supply terminals 9 and 10, the contact point c is a weak wind terminal a or a strong wind terminal b. In the low wind operating state by selectively contacting the contact (c) of the air volume switching switch (8) with the weak wind terminal (a) or the strong wind terminal (b) by connecting through the air flow switching switch (8) that is selectively in contact with It is to be switched to the strong wind operation state.
그런데 이러한 냉방용 공기조화기에 있어서는 통상 증발기(5)에서 냉각된 냉기를 실내에 강제 순환시켜 냉방을 행함과 아울러 실내공기중에 포함된 습기를 증발기(5)의 표면에 부착시켜 제습작용을 병행하게 되므로 증발기(5)의 표면은 물방울로 가득 찬 상태로 되며 드레인 팬(Drain Pan)에 자연 낙하시켜 실외로 배출시키고 있다.However, in such an air conditioner for cooling, the cold air cooled by the evaporator 5 is forcedly circulated in the room to perform cooling, and the moisture contained in the indoor air is attached to the surface of the evaporator 5 to perform a dehumidification effect. The surface of the evaporator 5 is filled with water droplets and is naturally dropped in a drain pan and discharged to the outside.
그러나 종래에는 풍량절환스위치(8)의 접점(c)이 약품용 단자(a)에 접속된 상태 즉, 약풍운전상태에서 상기 접점(c)을 강풍용단자(b)에 접촉시켜 강풍운전상태로 절환시킴에 있어 상기 접점(c)이 강풍용단자(b)에 접촉되는 순간부터 송풍기(2)는 강풍운전상태로 돌입되기 때문에 증발기(5)의 표면에 물방울이 가득찬 상태에서 급격한 송풍상태의 변화 즉, 약풍상태에서 강풍상태로의 급격한 변화가 발생되어 증발기(5)의 표면에 부착되어 있던 물방울이 냉풍과 함께 토출구(7)를 통해 실내로 비산 분출되면서 실내를 오손시키거나 실내의 거주자에게 날아가게 되는 등 쾌적한 냉방을 기할 수 없게 되는 폐단이 있었다.However, conventionally, the contact c of the air volume switching switch 8 is connected to the chemical terminal a, that is, the contact c is brought into the strong wind operation state by contacting the contact c with the strong wind terminal b in the weak wind operation state. In the switching, since the blower 2 enters the strong wind driving state from the moment when the contact point c contacts the strong wind terminal b, the air blower suddenly blows in a state where water droplets are filled on the surface of the evaporator 5. That is, a sudden change from a weak wind state to a strong wind state occurs, and water droplets attached to the surface of the evaporator 5 splashes into the room through the discharge port 7 together with the cold air, and deteriorates the room or causes damage to the occupants of the room. There was a feeling of being unable to provide comfortable air-conditioning such as flying away.
따라서 본 고안은 이러한 종래의 폐단을 해소하기 위하여 냉방전용 또는 냉난방 겸용 공기조화기의 냉방운전중 증발기 표면에 물방울이 맺혀있는 상태에서는 약풍운전상태에서 강풍운전상태로의 절환시 타이머에 의한 설정시간동안 지연시킨 후 강풍운전상태로 되도록 함과 아울러 증발기 표면에 물방울이 맺혀있지 않은 상태에서는 약풍운전상태에서 강풍운전상태로의 절환이 바로 이루어 지도록 함으로써 물방울이 실내나 실내거주자에게 비산되는 일이 없도록 한 공기조화기의 풍량조절장치를 제공하려는 것이다.Therefore, the present invention is designed to solve the above-mentioned dead ends, during the setting time by the timer at the time of switching from the weak wind operation state to the strong wind operation state in the state of condensation on the surface of the evaporator during the cooling operation of the air conditioner for exclusive use of air conditioning or air conditioning. After delaying, the air is in a strong wind operation state and when there is no water droplets on the surface of the evaporator, the air flow is prevented from dropping to indoor or indoor residents by switching from the low wind operation state to the strong wind operation state immediately. It is to provide an airflow control device of the conditioner.
또한 본 고안은 히트펌프(Heat Pump)가 설치된 냉난방겸용 공기조화기에 적용한 경우 실내열 교환기에 물방울이 맺혀있자 않는 난방운전중에는 약품운전상태에서 약풍운전상태로의 절환이 바로 이루어지도록 하려는 것이다.In addition, the present invention is intended to immediately switch from the chemical operation state to the weak wind operation state during the heating operation that is not condensed with water droplets in the indoor heat exchanger when applied to a combined air-conditioning and air conditioner equipped with a heat pump (Heat Pump).
이하 본 고안을 제 3 도에 따라서 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to FIG. 3.
단 본 고안을 설명함에 있어서 필요한 경우에는 제 1 도를 참조하여 설명하기로 한다.However, when necessary to describe the present invention will be described with reference to FIG.
본 고안에 의한 공기조화기의 풍량조절장치는 제 1 도 및 제 3 도에 도시한 바와같이, 필터(3)가 설치된 흡입구(4)와 풍량조절그릴(6)이 설치된 토출구(7)를 보유하는 본체(1)내부에 송풍기(2)와 증발기(5)가 내장되고 상기 송풍기(2)를 접점(c)과 약풍용단자(a) 및 강풍용단자(b)를 보유하는 풍량 절환스위치(8)를 통해 전원공급단(9) (10)에 전기적으로 연결한것에 있어서, 상기 풍량절환스위치(8)의 강풍용단자(b)와 전원공급단(10)사이에는 타이머(11)를 연결하고, 상기 강풍용단자(b)와 송출기(2)사이에는 상기 타이머(11)의 타이머 접점(12)과 증발기(5)표면의 물방울감지용 센서의 접점(13)을 병렬로 연결하여서 된 것이다.The air volume control device of the air conditioner according to the present invention, as shown in Figs. 1 and 3, has an inlet port 4 is provided with a filter (3) and a discharge port 7 is provided with a flow rate control grill (6) Blower (2) and evaporator (5) is built in the main body (1) to the air flow rate switching switch having a contact (c), a weak wind terminal (a) and a strong wind terminal (b) to the blower ( 8) electrically connected to the power supply terminal (9) (10) through, the timer 11 is connected between the strong wind terminal (b) of the air flow rate switching switch (8) and the power supply terminal (10). In addition, between the strong wind terminal (b) and the discharge unit (2) by connecting in parallel with the timer contact 12 of the timer 11 and the contact point 13 of the sensor for detecting water droplets on the surface of the evaporator (5). .
상기 타이머(11)는 풍량절환스위치(8)의 접점(c)이 약풍용단자(a)에서 떨어져서 강풍용단자(b)에 접촉되면 전원이 인가되어 그후 소정시간 즉, 접점(c)이 약풍용단자(a)에서 덜어질때 전원이 차단된 송풍기(2)가 관성에 의해 계속 회전되다가 완전히 정지되기 전에 타이머 저점(12)이 ON으로 되도록 설정한다.The timer 11 is a power supply is applied when the contact (c) of the air volume switching switch 8 is separated from the weak air terminal (a) to contact the strong wind terminal (b), and then a predetermined time, that is, the contact (c) is weak wind The blower 2, which is powered off when it is removed from the terminal a, is continuously rotated by inertia and set so that the timer low 12 is turned on before being completely stopped.
상기 물방울 감지용 센서(미도시)의 접점(13)은 증발기(5)의 표면에 물방울이 없는 경우에 ON으로 되도록 한다.The contact point 13 of the sensor for detecting droplets is turned on when there is no droplet on the surface of the evaporator 5.
이와같이 구성된 본 고안의 풍량조절장치는, 상기 풍량절환스위치(8)의 접점(c)을 약풍용단자(a)에 접촉시키면 송풍기(2)가 약풍운전상태로 가동되어 냉방운전시에는 토출구(7)를 통해 냉풍을, 난방운전시에는 토출구(7)를 통해 온풍을 토출케 되는 것이다.The airflow control device of the present invention configured as described above, when the contact point c of the airflow switching switch 8 is in contact with the weak wind terminal a, the blower 2 is operated in the low wind operating state and the discharge port 7 during the cooling operation. Cool air through the), during the heating operation is to discharge the warm air through the discharge port (7).
상술한 약풍운전상태에서 풍량절환스위치(8)의 접점(c)를 강풍용단자(b)에 접촉시키면, 냉방운전중 증발기(5)표면에 물방울이 있는 경우에는 물방울 감지용 센서의 접점(13)이 OFF로 되고 타이머(11)의 접점(12)은 설정시간동안 OFF로 되므로 송풍기(2)에는 전원이 차단되고 다시 소정시간 후 타이머(11)의 접점(12)이 ON으로 되면서 송풍기(2)에는 전원이 인가되는 송풍기(2)는 강풍운전상태로 가동되는 것이다.When the contact point c of the air flow rate switching switch 8 is brought into contact with the strong wind terminal b in the above-described mild wind operation state, the contact point 13 of the sensor for detecting water droplets when there is water droplet on the surface of the evaporator 5 during the cooling operation. ) Is turned off and the contact 12 of the timer 11 is turned off for the set time, so that the power supply to the blower 2 is cut off, and after a predetermined time, the contact 12 of the timer 11 is turned on and the blower 2 ), The blower 2 to which power is applied is operated in a strong wind driving state.
즉, 풍량절환스위치(8)의 접점(c)을 약풍용단자(a)에서 강풍용단자(b)에 접촉되면 타이머(11)에는 전원이 인가되고 그후 설정시간 동안 타이머접점(12)은 OFF로 유지되고 증발기(5)표면에 물방울이 맺혀있는 상태이므로 물방울 감지용 센서의 접점(13)도 OFF로 되어 송풍기(2)에는 전원이 차단되어 송풍기(2)는 가동이 중지되나 그 자체의 관성력에 의해 계속회전되며, 그후 관성력에 의한 송풍기(2)의 회전이 완전히 정지되기 전까지의 시간으로 설정된 타이머(11)의 설정시간이 경과되면 타이머 접점(12)이 ON으로 되며 다시 송풍기(2)에는 강풍운전을 위한 전원이 인가되어 송풍기(2)는 강풍운전상태로 가동되기 시작한다.That is, when the contact c of the air volume switching switch 8 contacts the strong wind terminal b at the weak wind terminal a, power is supplied to the timer 11, and then the timer contact 12 is turned off for the set time. And the water droplets are condensed on the surface of the evaporator (5), so the contact point (13) of the sensor for detecting water droplets is also turned off, and the blower (2) is cut off so that the blower (2) is stopped. After the set time of the timer 11 is set to the time before the rotation of the blower 2 by the inertial force is completely stopped, the timer contact 12 is turned ON and the blower 2 is turned on again. Power is supplied for the strong wind driving and the blower 2 starts to operate in a strong wind driving state.
따라서 냉방운전중 약풍운전에서 강풍운전으로 절환함에 있어 약풍운전중 증발기(5)표면에 맺혀있던 물방울은 서서히 제거되어 드레인팬을 통해 외부로 제거되며 급격한 풍량변화(증가)가 일어나지 않으므로 물방울이 실내나 실내거주자에게 비산되는 일이 없게 되는 것이다.Therefore, when switching from the weak wind operation to the strong wind operation during the cooling operation, the water droplets formed on the surface of the evaporator (5) during the slow wind operation are gradually removed and removed to the outside through the drain pan. It will not be scattered by indoor residents.
또한 약풍운전에서 강풍운전으로 전환시 송풍기(2)는 관성에 의해 계속 회전하는 상태에서 강풍운전을 위해 재가동이 이루어지므로 송풍기(2)에서의 가동음이 발생되지 않게 된다.In addition, when switching from the weak wind operation to the strong wind operation, the blower 2 is restarted for the strong wind operation in the state of continuous rotation by inertia, so that the operation sound in the blower 2 is not generated.
한편 냉방운전 초기에 증발기(5) 표면에 물방울이 맺혀 있지 않은 상태에서는 물방울 감지용 센서의 접점(13)이 ON으로 되어 있으므로 타이머(11)와 무관하게 풍량절환 스위치(8)의 접점(c)을 강풍용단자(b)에 접촉시키면 즉시 강풍운전상태로 전환되며, 이때 증발기(5) 표면에 물방울이 맺혀있지 않은 상태이므로 물방울이 비산되는 일은 없게된다.On the other hand, when no water droplets are formed on the surface of the evaporator 5 at the beginning of the cooling operation, the contact point 13 of the water droplet detection sensor is turned on so that the contact point c of the air volume switching switch 8 is independent of the timer 11. When the contact with the strong wind terminal (b) is immediately switched to the strong wind driving state, in which the water droplets are not condensed on the surface of the evaporator (5) is not scattered.
또한 본 고안을 히트펌프가 설치된 냉, 난방 겸용 공기조화기에 적용한 경우에 있어서 난방운전시에는 실내 열교환기(미도시)에 물방울이 맺히지 않으므로 물방울 감지용 센서의 접점(13)이 ON으로 되어 타이머(11)와 무관하게 약풍운전시에 강풍 운전으로 바로 전환되는 것이다.In addition, when the present invention is applied to a combined air-conditioner equipped with a heat pump, water droplets do not form in the indoor heat exchanger (not shown) during the heating operation. Regardless of 11), it is converted to strong wind driving at low wind driving.
이상과 같이 본 고안에 의하면 냉방용 또는 냉방용 겸용 공기조화기의 냉방운전중 증발기에 물방울이 맺힌 상태에서는 약풍운전에서 강풍운전으로의 절환이 소정시간 경과후의 강풍운전상태로 되므로 물방울이 실내나 실내거주자에게 비산되지 않으면, 증발기에 물방울이 맺혀있지 않은 냉방운전 초기나 냉난방 겸용 공기조화기의 난방운전시에는 약풍운전에서 강풍운전으로의 절환이 바로 이루어지게 되어 쾌적상태로 운전할 수 있는 것이다.As described above, according to the present invention, when water droplets form in the evaporator during the cooling operation of the cooling or cooling air conditioner, the switching from the weak wind operation to the strong wind operation becomes a strong wind operation state after a predetermined time, so that the water droplets are indoors or indoors. If it is not scattered to the resident, during the initial cooling operation or the heating operation of the combined air-conditioning and air conditioner in which the water droplets are not condensed in the evaporator, switching from the weak wind operation to the strong wind operation can be performed in a comfortable state.
