이하 도면을 참조하여 본 발명에 따른 실시예를 설명한다.Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.

도 1은 본 발명에 따른 난방장치(1)의 구성을 나타내는 도면이다.1 is a view showing the configuration of a heating device 1 according to the present invention.

일반적인 난방장치와 동일하게, 본 발명의 따른 난방장치는 히터코어(10)를 포함하는 난방 장치, 증발기(20)를 포함하는 냉방 장치, 사용자로의 송풍을 행하는 블로워 장치(30) 및 이들을 제어하는 제어부(100)를 포함한다.As with the general heating apparatus, the heating apparatus according to the present invention includes a heating apparatus including a heater core 10, a cooling apparatus including an evaporator 20, a blower apparatus 30 for blowing air to a user, and controlling them. It includes a control unit 100.

본 발명에 따른 난방장치(1)의 제어부(100)는 기동 제어 진입조건 판정부(110) 및 난방 기동 제어부(120)를 포함한다.The control unit 100 of the heating apparatus 1 according to the present invention includes a start control entry condition determining unit 110 and a heating start control unit 120.

기동 제어 진입조건 판정부(110)는, 증발기(20)에 부착되어 있는 핀써모 센서(51), 히터코어(10)와 열교환을 행하는 냉각수의 온도를 측정하는 수온 센서(52), 외기 온도 센서(53), 실내 온도 센서(54) 등으로부터 주변 온도를 입력받는다. 또한, 기동 제어 진입조건 판정부(110)는, 사용자의 운전석 전면에 배치된 시동 점화 스위치(61), A/C 스위치(62), 오토 스위치(63) 및 난방온도 설정 노브(64) 등으로부터 상태 정보를 입력받는다. 기동 제어 진입조건 판정부(110)는, 상기 입력된 값에 의하여 난방 기동 제어의 여부를 결정하며, 난방기동 제어부(120)에서는 수온 센서(52) 등의 측정값에 따라 난방 기동 제어를 행한다.The start control entry condition determining unit 110 includes a pin thermo sensor 51 attached to the evaporator 20, a water temperature sensor 52 that measures the temperature of the cooling water that exchanges heat with the heater core 10, and an outside temperature sensor. 53, the ambient temperature is input from the room temperature sensor 54 or the like. In addition, the start control entry condition determining unit 110 includes a start ignition switch 61, an A / C switch 62, an auto switch 63, a heating temperature setting knob 64, and the like disposed on the front of a driver's seat. Receive status information. The start control entry condition determining unit 110 determines whether heating start control is performed based on the input value, and the heating start control unit 120 performs heating start control in accordance with measured values such as the water temperature sensor 52.

이하에서, 상기 기동 제어 동작의 진입 단계 및 기동 제어 단계를 구체적으로 설명한다.Hereinafter, the entry step and the start control step of the start control operation will be described in detail.

도 2는 본 발명에 따른 난방 제어 방법을 설명하는 흐름도이다.2 is a flowchart illustrating a heating control method according to the present invention.

본 발명에 따른 난방 제어로의 진입은 초기 기동시 1회에 한하며, 일반적으로 오토 스위치를 온으로 한 경우에 적용된다(S100).Entry into the heating control according to the present invention is limited to one time at initial start-up, and is generally applied when the auto switch is turned on (S100).

오토 스위치가 온으로 설정된 경우, 기동 제어 진입조건 판정부(110)는 냉각수의 수온을 측정하기 위해 장착된 수온 센서(52)로부터 냉각수의 온도를 입력받는다. 입력된 냉각수온이 기준수온(예를 들면 60℃) 이하인지를 판단한다(S110). 냉각수온이 기준수온보다 높은 경우에는, 냉각수와의 열교환을 통해 토출되는 바람의 온도가 충분히 따뜻하므로, 난방 기동 제어를 행하지 않아도 사용자에게 불쾌감을 주지 않는다.When the auto switch is set to on, the start control entry condition determining unit 110 receives the temperature of the cooling water from the water temperature sensor 52 mounted to measure the temperature of the cooling water. It is determined whether the input cooling water temperature is lower than the reference water temperature (for example, 60 ° C.) (S110). If the cooling water temperature is higher than the reference water temperature, the temperature of the wind discharged through the heat exchange with the cooling water is sufficiently warm, so that the user is not offended even if the heating start control is not performed.

냉각수의 온도가 상기 기준수온 이하인 경우, 기동 제어 진입조건 판정부(110)는 외기 온도 센서(53)에 의해 측정된 온도를 입력받아, 이 온도가 소정의 온도, 예를 들면 10℃ 이하인지를 판단한다(S120). 외기 온도가 상기 소정의 온도 이상인 경우에는, 외기를 통해 들어오는 온도가 낮지 않고, 사용자에게 토출되는 바람이 불쾌감을 줄 정도가 아니므로, 상기 난방 제어 기동을 행할 필요가 없다.When the temperature of the cooling water is equal to or lower than the reference water temperature, the start control entry condition determining unit 110 receives the temperature measured by the outdoor air temperature sensor 53 to determine whether the temperature is a predetermined temperature, for example, 10 ° C. or less. Determine (S120). When the outside air temperature is higher than or equal to the predetermined temperature, the temperature entering through the outside air is not low, and the wind discharged to the user is not so bad as to cause discomfort, so that the heating control start does not need to be performed.

외기 온도가 상기 소정의 온도 이하인 경우, 기동 제어 진입조건 판정부(110)는 난방 설정 온도가 실내 온도 + 3℃ 이상인지 여부를 판단한다(S130). 난방 설정 온도가 실내 온도 + 3℃보다 낮은 경우에는 토출되는 바람의 온도가 실내 온도와 차이가 많지 않기 때문에 사용자가 불쾌감을 느끼지 않는다.When the outside air temperature is less than or equal to the predetermined temperature, the start control entry condition determining unit 110 determines whether the heating set temperature is room temperature + 3 ° C. or more (S130). If the heating set temperature is lower than the room temperature + 3 ℃, the user does not feel uncomfortable because the temperature of the discharged wind is not much different from the room temperature.

난방 설정 온도가 실내 온도 + 3℃ 이상인 경우에, 즉, 상기의 조건이 모두 만족하는 경우에, 비로소 난방 기동 제어 단계(S140)로 진입하게 된다. When the heating set temperature is room temperature + 3 ° C. or more, that is, when all of the above conditions are satisfied, the heating start control step S140 is finally entered.

본 발명의 난방 기동 제어 단계는 상기 조건을 모두 만족하는 경우에, 토출되는 바람이 사용자에게 불쾌감을 줄 수 있다는 사실에 근거하여, 토출되는 풍량을 조절한다. 예를 들면, 풍량은 블로워 전압을 조절함으로써 조절될 수 있으며, 상기 온도 조건과 블로워 전압과의 관계를 도 2에 나타낸다.The heating start control step of the present invention adjusts the amount of discharged air based on the fact that the discharged wind may cause discomfort to the user when all of the above conditions are satisfied. For example, the air volume can be adjusted by adjusting the blower voltage, and the relationship between the temperature condition and the blower voltage is shown in FIG. 2.

도 3는 수온 센서에 의해 측정된 냉각수의 온도와 블로워 전압과의 관계를 나타낸다. 상기 그래프는, 난방 기동 제어에 진입한 경우, 즉 상기의 조건을 모두 만족하는 경우에만 적용된다.3 shows the relationship between the blower voltage and the temperature of the cooling water measured by the water temperature sensor. The graph is applied only when entering the heating start control, that is, when all of the above conditions are satisfied.

수온이 T1 이하인 경우에는, 토출되는 바람이 차가운 상태이므로, 블로워 전압을 최소로 하여 토출 풍량을 최소화한다. 수온 T1은, 예를 들면 체온인 36℃이다. 수온이 T2 이상인 경우에는, 블로워 전압이 최대가 되며, 이 온도 T2는 사용자가 불쾌감을 느끼지 않도록 하는 충분히 높은 냉각수 온도로, 예를 들면 60℃이다.If the water temperature is T1 or less, since the wind to be discharged is cold, the blower voltage is minimized to minimize the amount of discharge air. Water temperature T1 is 36 degreeC which is body temperature, for example. When the water temperature is T2 or more, the blower voltage becomes maximum, and this temperature T2 is a sufficiently high cooling water temperature to prevent the user from feeling uncomfortable, for example, 60 ° C.

수온이 T1과 T2 사이인 경우에는, 수온의 상승에 따라 블로워 전압이 상승하게 하여, 풍량이 점차 커지도록 하는 것이 바람직하며, 수온의 상승과 블로워 전압은 비례하여 상승하도록 하는 것이 바람직하지만, 이에 한정되지 않고 기울기가 상승하는 곡선으로서 블로워 전압이 상승할 수도 있고, 기울기가 하강하는 곡선으로 블로워 전압이 상승할 수도 있다.In the case where the water temperature is between T1 and T2, it is preferable that the blower voltage increases as the water temperature rises, so that the air volume gradually increases, and it is preferable that the rise of the water temperature and the blower voltage rise proportionally. Instead, the blower voltage may rise as a curve in which the slope rises, or the blower voltage may rise in a curve in which the slope falls.

따라서 이러한 난방 기동 제어에 의하여, 초기 사용자가 느끼는 불쾌감은 훨씬 저감될 수 있다. 또한, 난방 기동 제어 시에, 수온이 일정 온도, 예를 들면 온도 T2에 이르거나, 상기 진입 조건을 벗어나게 되면, 상기의 기동 제어는 해제되고, 원래의 자동온도조절 시스템에 의한 난방을 행하게 된다(S150). 이러한 난방 기동 제어의 해제는, 사용자에게 더 이상의 불쾌감을 느끼지 않도록 하는 조건이라면, 다른 측정치에 의한 조건에 의해서도 가능하다.Therefore, by this heating start control, the discomfort felt by the initial user can be further reduced. In addition, in the heating start control, when the water temperature reaches a certain temperature, for example, the temperature T2 or out of the entry condition, the start control is released and the heating is performed by the original thermostat system ( S150). The release of the heating start control can be performed by other measurement values as long as it is a condition that the user does not feel any discomfort.

비록 상술한 실시예가 일 실시형태에 한하여 설명되었지만, 본 발명의 난방 기동 제어는 이에 한정되지 않는다. 예를 들면, 난방 기동 제어로의 진입 조건은, 상기 조건 중 일부의 조건만을 취할수도 있으며, 기타 제어부로 입력되는 다른 환경 측정값을 이용하는 것도 가능하다. 또한, 난방 기동 제어는 단지 토출 풍량을 조절하는 것뿐만 아니라, 토출 방향의 조절 등 사용자의 불쾌감을 저감시키기 위한 다른 방법을 이용하는 것도 가능하다.Although the above-described embodiment has been described with reference to one embodiment, the heating start control of the present invention is not limited thereto. For example, the entry condition to the heating start control may take only some of the above conditions, or may use other environmental measurement values input to other control units. In addition, the heating start control can not only adjust the discharge air volume but also use other methods for reducing the discomfort of the user, such as adjusting the discharge direction.

상술한 바와 같이, 난방장치의 초기 가동시에, 난방 기동 제어를 행함으로써 원하지 않는 온도의 공기가 블로워를 통해 토출되는 것을 최소화할 수 있으며, 이에 따라 사용자의 불쾌감을 저감시킬 수 있는 효과가 있다.As described above, during the initial operation of the heating apparatus, by performing the heating start control, it is possible to minimize the discharge of air of unwanted temperature through the blower, thereby reducing the user's discomfort.
