본 발명은 송풍팬장치에 관한 것으로서, 보다 상세하게는 발열영역을 향해 공기를 강제로 송풍시키는 장치에 관한 것이다.The present invention relates to a blower fan apparatus, and more particularly to a device for forcibly blowing air toward the heat generating region.

전자통신장비, 전자제품 등과 같이 동작상태에서 열을 발생시키는 장치(이하 "발열성 장치"라고 함)는 설치영역의 온도상승에 따라 장치성능이 저하될 염려가 있으므로 발열성 장치 자체에 또는 발열성 장치의 인접영역에 설치되어 발열영역을 향해 공기를 강제로 송풍시키는 송풍팬장치가 안출되어 사용되고 있다.Devices that generate heat in the operating state (hereinafter referred to as "heat generating devices"), such as electronic communication equipment and electronic products, may cause deterioration of device performance due to temperature rise in the installation area. Blowing fan apparatuses installed in adjacent areas of the apparatus and forcibly blowing air toward the heat generating region have been devised and used.

도3은 종래의 송풍팬장치의 분해사시도이고, 도4는 종래의 송풍팬장치의 기능별 블록도이다. Figure 3 is an exploded perspective view of a conventional blower fan, Figure 4 is a functional block diagram of a conventional blower fan device.

종래의 송풍팬장치는, 이들 도면에 도시된 바와 같이, 하우징(111)과, 하우징(111)에 설치된 메모리(112), 회전날개(113), 팬모터(114) 및 회전수검출부(115)와, 회전날개(113)의 전방영역에 설치된 온도센서(116)와, 고장상태를 출력하기 위한 고장상태출력부(117)와, 회전수검출부(115)에서 검출한 회전수에 기초하여 고장상태를 고장상태출력부(117)를 통해 출력하는 제어부(118)를 갖고 있다.The conventional blower fan device, as shown in these figures, the housing 111, the memory 112 installed on the housing 111, the rotary blade 113, the fan motor 114 and the rotational speed detection unit 115 And a failure state based on the temperature sensor 116 provided in the front region of the rotary blade 113, the failure state output unit 117 for outputting the failure state, and the rotation speed detected by the rotation speed detection unit 115. It has a control unit 118 for outputting through the fault state output unit 117.

하우징(111)은 공기유입구(111a)와 공기배출구(111b)가 대향하도록 형성되어 있다.The housing 111 is formed such that the air inlet 111a and the air outlet 111b face each other.

메모리(112)에는 팬모터(114)의 고장회전수와 공기배출구(111b)를 통해 배출되는 공기가 도달하는 영역의 온도와 팬모터(114)의 회전수사이의 대응관계를 나타내는 온도회전수대응정보가 저장되어 있다.The memory 112 corresponds to a temperature rotational speed indicating a correspondence relationship between the failure speed of the fan motor 114 and the temperature of the region where the air discharged through the air outlet 111b reaches and the rotational speed of the fan motor 114. The information is stored.

고장회전수는 고장상태를 판단하는 기준이 된다.The fault rotation speed is a criterion for determining the fault condition.

온도회전수대응정보는 회전날개(113)의 전방영역 온도를 고온영역, 중온영역, 저온영역으로 구분하고, 고온영역이 중온영역보다 팬모터(114)의 회전수가 높아지고 중온영역이 저온영역보다 팬모터(114)의 회전수가 높아지도록 생성할 수 있다.The temperature rotational response information divides the front zone temperature of the rotor blade 113 into a high temperature zone, a medium temperature zone, and a low temperature zone, and the rotation speed of the fan motor 114 is higher than that of the mid temperature zone, and the mid temperature zone is higher than the low temperature zone. The rotation speed of the motor 114 may be generated to be high.

회전날개(113)는 회전 동작시 공기유입구(111a)로부터 유입되는 공기를 공기배출구(111b)를 향해 토출할 수 있도록 하우징(111)에 설치된다.The rotary blade 113 is installed in the housing 111 to discharge the air flowing from the air inlet 111a toward the air outlet 111b during the rotation operation.

팬모터(114)는 회전날개(113)를 회전 구동할 수 있도록 모터축이 회전날개(113)에 연결되어 있다.The fan motor 114 has a motor shaft connected to the rotary blade 113 so as to drive the rotary blade 113 in rotation.

회전수검출부(115)는 종래 널리 알려진 바와 같이 다음과 같은 방법으로 구현할 수 있다.The rotation speed detection unit 115 may be implemented by the following method as is widely known in the art.

즉, 팬모터(114)의 모터축에 둘레연부에 광차단영역과 광투과영역이 교대로 형성된 회전판을 설치한다.That is, the rotating plate is provided on the motor shaft of the fan motor 114 alternately formed with the light blocking region and the light transmitting region.

다음에 회전판의 광차단영역과 광투과영역이 회전하는 경로에 수직인 방향을 따라 상호 대향하도록 발광소자와 수광소자를 설치한다.Next, the light emitting element and the light receiving element are provided so as to face each other along the direction perpendicular to the path in which the light blocking region and the light transmitting region of the rotating plate rotate.

수광소자에서 생성된 펄스를 제어부(118)를 전송하면 제어부(118)는 수광소자로부터의 펄스를 계수하여 팬모터(114)의 회전수를 산출할 수 있다.When the control unit 118 transmits the pulse generated by the light receiving element, the control unit 118 may calculate the rotation speed of the fan motor 114 by counting the pulse from the light receiving element.

고장상태출력부(117)는 경보램프, 엘씨디(LCD) 등을 사용하여 구현할 수 있다. 고장상태출력부로서 엘씨디를 채용하는 경우 메모리(112)에 고장상태표식을 미리 저장한다. Fault status output unit 117 may be implemented using an alarm lamp, LCD (LCD) and the like. When employing the LCD as the fault state output unit, the fault state marker is stored in advance in the memory 112.

제어부(118)는 온도센서(116)로부터 입력되는 온도값을 메모리(112)에 저장된 온도회전수대응정보와 비교하여 팬모터(114)의 회전수를 제어한다. 여기서 팬모터(114)의 회전수 제어는 팬모터(114)에 동작전압을 공급하는 전압공급부(도시되지 않음)와 팬모터(114)사이에 개재된 스위칭회로(도시되지 않음)를 통해 팬모터(114)에 고온영역에 대응하는 회전수, 중온영역에 대응하는 회전수와 저온영역에 대응하 는 회전수에 상응하는 동작전압을 공급하는 방법 등으로 구현할 수 있다.The controller 118 controls the rotation speed of the fan motor 114 by comparing the temperature value input from the temperature sensor 116 with the temperature rotation speed corresponding information stored in the memory 112. The rotation speed control of the fan motor 114 is a fan motor through a switching circuit (not shown) interposed between the voltage supply unit (not shown) for supplying an operating voltage to the fan motor 114 and the fan motor 114. The operation speed corresponding to the rotation speed corresponding to the high temperature region, the rotation speed corresponding to the middle temperature region, and the rotation speed corresponding to the low temperature region may be provided to the 114.

그리고 제어부(118)는 회전수검출부(115)로부터 입력되는 팬모터(114)의 실제회전수를 메모리(112)에 저장된 팬모터(114)의 고장회전수를 비교하여 팬모터(114)의 실제회전수가 고장회전수보다 작아지면 고장상태가 발생하였음을 고장상태출력부(117)를 통해 출력시킨다.The controller 118 compares the actual rotational speed of the fan motor 114 input from the rotational speed detection unit 115 to the faulty rotational speed of the fan motor 114 stored in the memory 112 to determine the actual rotation of the fan motor 114. When the number of revolutions is smaller than the number of faults, a fault condition is output through the fault condition output unit 117.

그런데 종래의 송풍팬장치에 따르면, 고장상태출력부(117)를 통해 출력되는 고장상태의 확인이 지체되는 경우 고장상태의 확인시까지 송풍동작이 일어나지 않기 때문에 발열성 장치를 향한 송풍동작이 안정적으로 이루어질 수 없다는 문제점이 있었다.By the way, according to the conventional blower fan device, if the confirmation of the failure state output through the failure state output unit 117 is delayed, since the blow operation does not occur until the confirmation of the failure state, the blowing operation toward the heat generating device is stable. There was a problem that could not be achieved.

그리고 고장상태가 장기간 사용에 의한 것인지를 고장상태출력부(117)의 출력을 통해 서는 알 수 없기 때문에 적절한 시기에 부품을 교체할 수 없다는 문제점이 있었다.And there is a problem that the parts can not be replaced at the appropriate time because it is not known through the output of the failure state output unit 117 whether the failure state is due to long-term use.

따라서 본 발명의 목적은, 송풍동작이 안정적으로 이루어질 수 있고 부품교체시기를 알려줄 수 있도록 한 송풍팬장치를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a blowing fan apparatus which can stably perform a blowing operation and inform a replacement time of parts.

여기서 공기배출구를 통해 배출되는 공기가 도달하는 영역의 온도에 따라 팬모터의 회전수가 달라지는 경우에도 간단한 장치구조를 가지고 정확한 교체시기를 알려줄 수 있도록, 상기 공기배출구를 통해 배출되는 송풍공기가 도달하는 영역의 온도를 검출하는 온도검출부를 더 포함하고; 상기 메모리에는 상기 공기배출구를 통해 배출되는 공기가 도달하는 영역의 온도와 상기 팬모터의 회전수사이의 대응관계를 나타내는 온도회전수대응정보가 저장되어 있고, 상기 한계누적량은 상기 팬모터의 회전수에 대한 한계누적량이며, 상기 제어부는 상기 온도검출부에서 검출한 온도와 상기 메모리에 저장된 온도회전수대응정보에 기초하여 상기 팬모터의 회전수를 제어하도록 구성하는 것이 바람직하다.Here, the area where the blown air discharged through the air outlet reaches, so that even when the rotation speed of the fan motor is changed according to the temperature of the area where the air discharged through the air outlet reaches, it has a simple device structure to inform the correct replacement time. Further comprising a temperature detection unit for detecting the temperature of; The memory stores temperature rotation speed correspondence information indicating a correspondence relationship between the temperature of a region where the air discharged through the air discharge port reaches and the rotation speed of the fan motor, and the limit accumulation amount is the rotation speed of the fan motor. It is preferable that the control unit is configured to control the rotational speed of the fan motor based on the temperature detected by the temperature detector and the temperature rotational response information stored in the memory.

이하에서, 첨부도면을 참조하여 본 발명을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 실시예에 따른 송풍팬장치는, 이들 도면에 도시된 바와 같이, 하 우징(11)과, 하우징(11)에 설치된 메모리(12), 회전날개(13), 팬모터(14) 및 회전수검출부(15)와, 회전날개(13)의 전방영역에 설치된 온도센서(16)와, 교체시기가 도달했음을 나타내는 교체시기경보를 출력하기 위한 경보출력부(17)와, 회전수검출부(15)에서 검출한 회전수에 기초하여 교체시기경보를 경보출력부(17)를 통해 출력하는 제어부(18)를 갖고 있다.Blowing fan apparatus according to an embodiment of the present invention, as shown in these figures, the housing 11, the memory 12 installed in the housing 11, the rotary blade 13, the fan motor 14 and The rotation speed detection unit 15, the temperature sensor 16 installed in the front region of the rotation blade 13, the alarm output unit 17 for outputting the replacement time alarm indicating that the replacement time has been reached, and the rotation speed detection unit ( The control unit 18 outputs the replacement time alarm through the alarm output unit 17 based on the rotation speed detected in 15).

하우징(11)은 공기유입구(11a)와 공기배출구(11b)가 대향하도록 형성되어 있다.The housing 11 is formed such that the air inlet 11a and the air outlet 11b face each other.

메모리(12)에는 팬모터(14)의 회전수에 대한 한계누적량과 공기배출구(11b)를 통해 배출되는 공기가 도달하는 영역의 온도와 팬모터(14)의 회전수사이의 대응관계를 나타내는 온도회전수대응정보가 저장되어 있다.The memory 12 has a temperature indicating a correspondence relationship between the limit accumulation amount of the rotational speed of the fan motor 14 and the temperature of the region where the air discharged through the air outlet 11b reaches and the rotational speed of the fan motor 14. Rotation speed correspondence information is stored.

한계누적량은 교체시기의 도래여부를 판단하는 기준이 된다.The limit accumulation amount serves as a criterion for judging whether the replacement time has come.

온도회전수대응정보는 회전날개(13)의 전방영역 온도를 고온영역, 중온영역, 저온영역으로 구분하고, 고온영역이 중온영역보다 팬모터(14)의 회전수가 높아지고 중온영역이 저온영역보다 팬모터(14)의 회전수가 높아지도록 생성할 수 있다.The temperature rotation speed correspondence information divides the front zone temperature of the rotor blade into a high temperature zone, a medium temperature zone, and a low temperature zone. The rotation speed of the motor 14 can be generated to be high.

회전날개(13)는 회전 동작시 공기유입구(11a)로부터 유입되는 공기를 공기배출구(11b)를 향해 토출할 수 있도록 하우징(11)에 설치된다.The rotary blade 13 is installed in the housing 11 to discharge the air flowing from the air inlet 11a toward the air outlet 11b during the rotation operation.

팬모터(14)는 회전날개(13)를 회전 구동할 수 있도록 모터축이 회전날개(13)에 연결되어 있다.The fan motor 14 has a motor shaft connected to the rotary blade 13 so as to drive the rotary blade 13 in rotation.

회전수검출부(15)는 종래 널리 알려진 바와 같이 다음과 같은 방법으로 구현할 수 있다.The rotation speed detection unit 15 may be implemented by the following method as is widely known in the art.

즉, 팬모터(14)의 모터축에 둘레연부에 광차단영역과 광투과영역이 교대로 형성된 회전판을 설치한다.That is, the rotating plate is provided on the motor shaft of the fan motor 14 with alternately formed light blocking regions and light transmitting regions.

다음에 회전판의 광차단영역과 광투과영역이 회전하는 경로에 수직인 방향을 따라 상호 대향하도록 발광소자와 수광소자를 설치한다.Next, the light emitting element and the light receiving element are provided so as to face each other along the direction perpendicular to the path in which the light blocking region and the light transmitting region of the rotating plate rotate.

수광소자에서 생성된 펄스를 제어부(18)를 전송하면 제어부(18)는 수광소자로부터의 펄스를 계수하여 팬모터(14)의 회전수를 산출할 수 있다.When the control unit 18 transmits the pulse generated by the light receiving element, the control unit 18 may calculate the rotation speed of the fan motor 14 by counting the pulse from the light receiving element.

경보출력부(17)는 경보램프, 엘씨디(LCD) 등을 사용하여 구현할 수 있다. 경보출력부로서 엘씨디를 채용하는 경우 메모리(12)에 교체시기경보표식을 미리 저장한다.Alarm output unit 17 may be implemented using an alarm lamp, LCD (LCD) and the like. When employing the LCD as the alarm output unit, the replacement time alarm marker is stored in advance in the memory 12.

제어부(18)는 온도센서(16)로부터 입력되는 온도값을 메모리(12)에 저장된 온도회전수대응정보와 비교하여 팬모터(14)의 회전수를 제어한다. 여기서 팬모터(14)의 회전수 제어는 팬모터에 동작전압을 공급하는 전압공급부(도시되지 않음)와 팬모터(14)사이에 개재된 스위칭회로(도시되지 않음)를 통해 팬모터(14)에 고온영역에 대응하는 회전수, 중온영역에 대응하는 회전수와 저온영역에 대응하는 회전수에 상응하는 동작전압을 공급하는 방법 등으로 구현할 수 있다.The controller 18 controls the rotation speed of the fan motor 14 by comparing the temperature value input from the temperature sensor 16 with the temperature rotation speed corresponding information stored in the memory 12.
