종래의 에어콘에 있어서는 풍량 조절이 수동으로 수행되어 쾌적 온도상태를 유지하는데 여러번의 조작이 수행되므로 쾌적공조를 정확히 유지하기가 어렵게 될 뿐아니라 사용자에게 불편을 주게되는 문제점이 있었다.In the conventional air conditioner, the air volume adjustment is performed manually to maintain a comfortable temperature state, so that the operation of the air conditioner is not only difficult to accurately maintain the air conditioning, but also causes inconvenience to the user.

본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위해서 실내온도와 설정온도의 차이에 따라 풍량조절을 자동으로 수행하여 쾌적 공조를 실현하도록 한 에어콘의 풍량 조절 방법을 창안한 것이다.An object of the present invention is to devise a method for adjusting the air volume of the air conditioner to realize a comfortable air conditioning by automatically adjusting the air flow in accordance with the difference between the room temperature and the set temperature in order to solve the conventional problems as described above.

이와같은 목적을 실행하기 위한 본 발명은 자동 운전 모드로 잔환될 경우 실내온도를 쾌적 온도 상태로 유지하게 하며, 사용자가 위치한 곳의 온도를 정확히 감지하여 에어콘 본체에서 감지한 온도와 차이가 있을 경우, 그 차이만큼 자동 보상하여 에어콘을 운전하고, 춥거나 더운상태를 리모콘의 사용자가 키(Key)로 별도 제어하여 다른 환경에서도 원하는 에어콘 운전을 수행하게 하는 것을 특징으로 하는 것으로, 이하 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention for carrying out the above object is to maintain the indoor temperature in a comfortable temperature state when remaining in the automatic operation mode, and if there is a difference from the temperature detected by the air conditioner body by accurately detecting the temperature where the user is located, Automatically compensates the difference to drive the air conditioner, the user of the remote control to control the cold or hot state with a key (Key) to perform the desired air conditioner in other environments, refer to the accompanying drawings below When described in detail as follows.

Thermistor (TH1) for applying a temperature sensing state to), the switch (SW1) connected to the power supply (Vcc) side for applying an automatic operation state to the main body microcomputer (2), and the output of the main body microcomputer (2) A buffer IC1 for transmitting the outputs of the terminals R0-R2, and a relay RY1 for controlling the air volume in one, two, and three stages by controlling the fan motor 3 through the output of the buffer IC1. RY2 and RY3, the thermistor TH2 connected to the power supply Vcc side to apply the temperature state of the user position to the remote controller micom 4, and the resistor R2 connected to the power supply Vcc side. It is connected to the switch (SW2) for applying the hot state operation to the remote controller micom (4), and connected to the power supply (Vcc) side to check the cold state operation through the resistor (R3) That is configured with a switch (SW3), it will now be described the operation and effect of the present invention with a signal flow diagram of FIG. 2 as reference for automatic flow rate control.

먼저 자동운전 스위치(SW1)를 온시키면 설정온도에 쾌적온도(K℃)를 설정하고, 더어미스터(THl)에서 현재온도를 감지하여 이를 설정온도와 비교한다. 이와같이 하여 현재온도와 쾌적온도의 차를 X℃라 한 상태에서, X℃≤0 일때 즉, 현재온도와 설정온도가 같거나, 설정온도가 더 높을때는 현재온도가 쾌적한 상태로 되었거나 더 낮은 상태로 되어 냉방운전을 할 필요가 없으므로 냉방운전을 오프시키고, 송풍운전을 하여 풍량을 1단으로 운전하게 한다.First, when the automatic operation switch (SW1) is turned on, the comfort temperature (K ℃) is set at the set temperature, and the present temperature is detected by the thermistor (THl) and compared with the set temperature. Thus, when the difference between the present temperature and the comfortable temperature is X ℃, when X ℃ ≤0, that is, when the present temperature and the set temperature are the same or when the set temperature is higher, the present temperature is made comfortable or lower. Since there is no need to perform cooling operation, the cooling operation is turned off and the airflow operation is performed to operate the air volume in one stage.

그리고 설정온도와 현재온도 차가 0<X℃≤1로 될때 즉, 현재온도가 쾌적온도보다 1℃가량 높게 될 경우 실내온도를 낮추어야 하므로 냉방운전을 온시키고, 풍량은 1단으로 운전시켜 약풍으로서 쾌적온도를 찾아가게 한다.When the difference between the set temperature and the present temperature becomes 0 <X ℃ ≤1, that is, when the present temperature is about 1 ℃ higher than the comfort temperature, the indoor temperature must be lowered. Let's find the temperature.

또한, 설정온도와 현재온도 차가 1<X℃≤2℃로 될때 즉, 현재온도가 쾌적온도보다 2℃가량 높을 경우 실내온도를 2℃정도 낮추어야 하므로 냉방운전을 온시킨 후 풍량을 2단으로 운전시키며, 온도차가 X℃≥3으로 될때 즉, 현재온도가 쾌적온도 보다 3℃이상 높을 경우는 상기와 마찬가지로 3℃ 정도 실내온도를 낮추어야 하므로 냉방운전을 온시킨 후 풍량을 3단으로 작동시켜 빨리 쾌적온도를 만들게 한다.In addition, when the difference between the set temperature and the present temperature becomes 1 <X ℃ ≤2 ℃, that is, when the present temperature is about 2 ℃ higher than the comfortable temperature, the room temperature should be lowered by about 2 ℃. When the temperature difference is X ℃ ≥3, that is, when the present temperature is higher than 3 ℃ above the comfort temperature, the room temperature should be lowered by about 3 ℃ as mentioned above. Make temperature.

따라서 상기와 같이 에어콘을 자동운전 모드로 전환시키면 쾌적온도 K℃를 유지하여 일일이 풍량변화를 시킬 필요없이 실내온도를 쾌적온도로 자동운전이 가능하게 되는 것이다.Therefore, when the air conditioner is switched to the automatic operation mode as described above, it is possible to automatically operate the indoor temperature to the comfortable temperature without having to change the air volume by maintaining the comfortable temperature K ℃.

그러나 외부에서 막 들어왔거나 격렬한 운동을 했을 경우 쾌적온도 K℃에서 만족감을 느낄 수 없으므로 이를 극복하기 위해 리모콘의 덥다 키(Key)인 스위치(SW2)와, 설정온도가 낮다고 생각될 때를 위해 춥다키(Key)인 스위치(SW3)를 사용하여 풍량을 제어한다.However, if you just came in from the outside or exercised hard, you cannot feel satisfaction at the comfortable temperature K ℃. To overcome this, it is cold for the switch (SW2), which is the key of the remote control, and when you think the set temperature is low. The air volume is controlled by using the switch SW3, which is a key.

이때 리모콘의 온도센서인 더어미스터(TH2)에서 감지한 실내온도와 에어콘 본체의 온도센서인 더어미스터(TH1)에서 감지한 실내온도를 비교하여 가장 적합한 운전을 하도록 제어하며, 이하 그 원리를 설명한다.At this time, the indoor temperature detected by the temperature sensor (TH2) of the remote control and the indoor temperature detected by the temperature sensor (TH1) of the air conditioner main body are controlled to perform the most suitable operation. .

우선 리모콘에서 감지한 실내온도를 R℃, 본체에서 감지한 실내온도를 B℃라 한 상태에서 R℃≤B℃일때, 사용자가 덥다 스위치(SW2)를 온시켰을 경우 현재온도≥설정온도이면 실내온도를 낮추기 위해 "설정온도=설정온도-l℃"를 수행하고, 현재온도<설정온도이면 "설정온도=현재온도-l℃"을 수행하여 실내온도를 쾌적온도로 유지해준다.First, if the room temperature detected by the remote control is R ℃ and the room temperature detected by the main body is B ℃, and the temperature is R ℃ ≤B ℃, the user turns on the SW2 switch. In order to lower the temperature, perform "set temperature = set temperature -1 ℃", and if the current temperature <set temperature, perform "set temperature = current temperature -1 ℃" to keep the indoor temperature at a comfortable temperature.

그리고, 상기 R℃≤B℃인 상태에서 사용자가 춥다 스위치(SW3)를 온시킬 경우에는 현재온도>설정온도일때 설정온도를 높여 실내온도를 쾌적온도로 유지해야 하므로 "설정온도=설정온도+1℃"를 수행한다.In addition, when the user turns on the switch SW3 that is cold in the state of R ° C≤B ° C, the indoor temperature should be maintained at a comfortable temperature by increasing the set temperature when the current temperature is> set temperature. ℃ ".

한편, R℃>B℃로 된 상태에서 덥다 스위치(SW2)를 온시키고 리모콘에서 감지한 실내온도 R℃-본체감지 실내온도 B℃=A℃라 할 경우 그 차이(A℃)가 0>A℃일때 현쟈온도≥설정온도로 된 상태에서는 설정온도를 -1℃씩 점차로 줄여가면서 실내온도를 쾌적온도로 유지한다.On the other hand, when the temperature is set to R ℃> B ℃, the switch (SW2) is turned on, and the room temperature detected by the remote controller is R ℃-the body sensing room temperature B ℃ = A ℃, and the difference (A ℃) is 0> A. In case of wise temperature ≥ set temperature, ℃ decreases set temperature by -1 ℃ and keeps room temperature at comfortable temperature.

즉, "설정온도=설정온도-1℃"를 수행한다.In other words, " set temperature = set temperature-1 占 폚 "

반면, 현재온도<설정온도로 된 상태에서는 "설정온도=현재온도-l℃"를 수행하여 실내온도를 쾌적온도로 유지한다.On the other hand, in the state where the present temperature <the set temperature, the temperature is maintained at a comfortable temperature by performing "set temperature = present temperature -1 ℃".

이는 실내온도가 낮은 상태이나 사용작 외부에서 막 들어왔거나 격렬한 운동을 했을 경우 쾌적온도를 만족하지 못하므로 현재온도를 점차로 낮추어 실내를 쾌적온도로 유지하는 것이다.This means that if the indoor temperature is low or the user just enters from the outside of the work or vigorously exercised, the comfort temperature is not satisfied. Therefore, the present temperature is gradually lowered to maintain the comfort temperature.

그리고 상기 R℃>B℃인 상태에서 덥다 스위치(SW2)가 온상태이고 0<A℃≤1로 될때 상기와 마찬가지로 현재온도≥설정온도로 되면 "설정온도=설정온돈-2℃"를 수행하고, 현재온도<설정온도로 되면 "설정온도=현재온도-2"를 수행한다.When the switch SW2 is on and 0 <A ℃ ≤1, the current temperature ≥ the set temperature is performed in the state where the temperature of R ℃> B ℃ is set. If the current temperature <set temperature, perform "Set temperature = Current temperature-2".

또한 상기 R℃>B℃에서 덥다 스위치(SW2) 온 상태이고 2≤A℃ 일때 현재온도≥설정온도 이면 "설정온도=설정온도-3℃"를수행하고, 현재온도<설정온도이면 "설정온도=현재온도-3℃"를 수행한다.In addition, if the current temperature ≥ the set temperature when the switch (SW2) is on and the temperature is higher than the set temperature (SW2) at 2 ° C and B ° C, "set temperature = set temperature -3 ℃" is performed. = Present temperature-3 ° C ".

한편 상기 R℃>B℃로 된 상태에서 사용자가 춥다 스위치(SW3)를 온시켠 현재온도>설정온도일때 "설정온도=설정온도＋1℃"를 수행하여 에어콘을 운전시킨다.On the other hand, the user is cold in the state of the R ℃> B ℃ when the current temperature is turned on when the switch (SW3)> set temperature by performing "set temperature = set temperature + 1 ℃" to operate the air conditioner.

이상에서 상세히 설명한 바와같이 본 발명은 자동운전 상태에서 사용자가 만족감을 느끼는 쾌적온도를 유지할 수 있으며, 사용자가 위치한 곳의 온도를 정확히 감지하여 에어콘 본체에서 감지한 온도와 차가 있을경우 이를 보상하여 에어콘 운전을 시킨다. 또한 별도의 춥다, 덥다에 대한 스위치(Key)를 사용하여 다른환경에서도 원하는 에어콘 운전을 유도할 수 있으므로 제품의 신뢰도를 높여 사용자에게 편리함을 제공할수 있는 효과가 있다.As described in detail above, the present invention can maintain a comfortable temperature in which the user feels satisfaction in the automatic driving state, and accurately detects the temperature of the user's location to compensate for the difference between the temperature detected by the air conditioner and the air conditioner operation. Let. In addition, by using a separate cold (hot) switch (Key) to drive the desired air conditioner in other environments, it has the effect of providing convenience to users by increasing the reliability of the product.
