Description

건설중장비 조종실의 출입구에 장착되는 외기 차단장치Outside air blocking device installed at the entrance of the construction equipment cockpit

본 고안은 건설중장비 조종실의 출입구에 장착되는 에어커텐(air curtain)방식의 외기 차단장치에 관한 것으로써, 특히 운전자가 수시로 조종실의 문을 여닫거나 계속 열어둔 상태로 두더라도 조종실 출입구 상부에 장착된 팬으로부터 고속으로 송풍되는 공기에 의해서 에어커텐이 형성되도록 함에 따라 조종실내의 온도가 외기온도의 영향을 크게 받지 않도록 하는 외기 차단장치에 관한 것이다.The present invention relates to an air curtain type air shutoff device that is mounted at the entrance of the cockpit of a heavy construction equipment. In particular, a fan mounted at the top of the cockpit entrance even if the driver keeps the door of the cockpit open or kept open at any time. The air curtain is formed by the air blown at a high speed from the air to the outside air blocking device so that the temperature in the cockpit is not significantly affected by the outside temperature.

도 1에 도시된 종래의 건설중장비에서는 조종실의 출입구에 별도의 외기 차단장치가 구비되어 있지 않아서 조종실내에서 에어콘이나 히터를 가동하다가 도어를 열 경우 외부에 있던 더운공기나 찬 공기가 조종실 내부로 쉽게 유입되므로 열손실 효과가 크게 발생되며, 조종실 도어를 장시간 열어둘 경우에는 조종실의 내부온도가 외부온도와 거의 일치하게 되므로 도어를 열어둔 상태에서는 작업하기 어렵게 되는 문제점이 있었다.In the conventional heavy construction equipment shown in Figure 1 is not equipped with a separate air blocking device in the doorway of the cockpit, if you open the door while operating the air conditioner or heater in the cockpit, the hot air or cold air from the outside easily into the cockpit Since the heat loss effect is greatly generated, when the cockpit door is opened for a long time, the inside temperature of the cockpit is almost identical to the outside temperature, which makes it difficult to work with the door open.

본 고안은 이외같은 문제점을 해결하기 위한 것으로, 조종실의 출입구 상부에 모터에 의해 고속으로 회전하는 송풍기를 구비하고 조종실 도어 개폐부에는 상기 송풍기의 작동을 제어하기 위한 스위치를 구비하여, 조종실 도어가 열릴때마다 출입구에 에어커튼(air curtain)이 형성되도록 함에 따라 열손실이 방지되도록 하고 있다.The present invention is to solve the same problem other than, the upper part of the cockpit is equipped with a blower that rotates at high speed by a motor and the cockpit door opening and closing portion is provided with a switch for controlling the operation of the blower, when the cockpit door is opened As air curtains are formed in the entrances every time, heat loss is prevented.

도 2는 본 고안장치가 설치된 조종실을 개략적으로 도시한 정면도 및 우측면도, 도 3은 본 고안장치의 작동상태를 설명하기 위해 도시한 우측면도로서, 상기 도면에서 보면, 휠로더와 같은 건설중장비 조종석(4)의 도어(2) 개폐부에는 중앙부에 돌출부(11)가 탄성결합된 누름 버튼스위치(1)가 설치되고, 상기 조종실(4) 출입구의 내측 상부에는 상기 누름 버튼스위치(1) ON시에 하방으로 공기를 배출하도록 작동되는 송풍기(3)가 설치되는데, 상기 송풍기(3)는 외주면에 다수개의 날개(34)가 인볼루트(involute) 형상으로 형성되어 있으며 모터축(35)에 축설되는 송풍팬(33)과, 상기 송풍팬(33)을 그 내부에 포함하도록 구성되며 측부에는 공기유입구(31)가 형성되고 하부에는 공기유출구(32)가 형성된 케이스(36)로 구성된다.2 is a front view and a right side view schematically showing a cockpit in which the present invention device is installed, and FIG. 3 is a right side view illustrating an operation state of the present invention device. The door 2 opening and closing portion of the door 4 is provided with a push button switch 1 having a protrusion 11 elastically coupled to a central portion thereof, and an inner upper portion of the entrance of the cockpit 4 when the push button switch 1 is turned on. A blower 3 is installed to discharge air downward, and the blower 3 has a plurality of wings 34 formed in an involute shape on an outer circumferential surface thereof and is blown on the motor shaft 35. The fan 33 and the blower fan 33 are configured to include therein, and an air inlet 31 is formed at a side thereof, and a case 36 is formed at the bottom thereof.

한편, 상기 누름 버튼스위치(1)는 냉장고 도어의 개폐부에 설치되는 스위치와 유사한 것으로서 돌출부(11)가 외부에 돌출되도록 탄성 결합된다.On the other hand, the push button switch 1 is similar to a switch installed in the opening and closing portion of the refrigerator door and is elastically coupled so that the protrusion 11 protrudes to the outside.

따라서 도어(2)를 닫을 경우에만 돌출부(11)가 눌려지게 되고 ON상태가 되는 것이다.Therefore, only when the door 2 is closed, the projection 11 is pressed and is in an ON state.

또한 상기 송풍기(3)는 송풍효과를 높이기 위해서 모터축(35)에 다수개의 송풍팬(33)을 축방향으로 연결한 형태로 사용된다.In addition, the blower 3 is used in the form of connecting a plurality of blow fans 33 to the motor shaft 35 in the axial direction in order to increase the blowing effect.

이와같이 구성되는 본 고안장치의 작용 및 효과는 다음과 같다.The operation and effects of the subject innovation device configured as described above are as follows.

도 3a는 도어가 닫힌상태를 도시한 우측면도로서, 운전자가 도어(2)를 완전히 닫게되면 누름버틈 스위치(1)의 돌출부(11)가 내측으로 눌려진 상태가 되므로 OFF상태가 된다. 따라서 송풍팬(33)은 작동하지 않는다.FIG. 3A is a right side view showing a closed state of the door, and when the driver completely closes the door 2, the protrusion 11 of the push-button switch 1 is in an inwardly pressed state, thereby being in an OFF state. Therefore, the blowing fan 33 does not operate.

이같은 상태에서 도 3b에서와 같이 운전자가 도어(2)를 약간 열게 되면 상기 누름버튼 스위치(1)의 돌출부(11)가 탄성력에 의해 돌출되므로 ON상태가 된다.In this state, as shown in FIG. 3B, when the driver slightly opens the door 2, the protrusion 11 of the push button switch 1 is protruded by the elastic force, and thus is in an ON state.

따라서 송풍팬(33)이 회전하며, 이때 공기유입구(31)를 통해 케이스(36) 내부로 유입된 공기가 송풍팬(33)이 외주면에 다수개 형성된 날개(34)로 부터 강한 바람으로 변하여, 케이스(36) 하부에 개구된 공기유출구(32)를 통해 하방으로 고속 배출된다.Therefore, the blowing fan 33 is rotated, and at this time, the air introduced into the case 36 through the air inlet 31 is changed into strong wind from the wings 34 formed with a plurality of blowing fans 33 on the outer circumferential surface thereof. High speed discharged downward through the air outlet 32 opened in the lower case 36.

이와같이 고속으로 배출되는 공기는 조종실의 내부공기와 외기를 단절하는 기능을 하게 되므로 에어커텐(air curtain) 효과가 얻어지게 된다.In this way, the air discharged at a high speed serves to disconnect the internal air from the cockpit and the air curtain effect is obtained.

따라서 도어(2)가 열려지더라도 조종실(4) 출입구를 경계로 한 공기이동이 억제되고 열손실 발생도 대폭 경감되는 것이다. 또한 상기 송풍팬(33) 외주며에 형성된 날개(34)는 인볼루우트 형상으로 형성되어 있으므로 송풍기능을 극대화 할 수 있게된다.Therefore, even if the door 2 is opened, air movement around the entrance of the cockpit 4 is suppressed and heat loss is greatly reduced. In addition, the wing 34 formed on the outer circumference of the blowing fan 33 is formed in an involut shape, thereby maximizing the blowing function.

위에서 설명한 바와 같이, 본 고안장치는 조종실의 출입구 상부에 모터에 의해 고속으로 회전하는 송풍기를 구비하고 조종실 도어 개폐부에는 상기 송풍기의 작동을 제어하기 위한 스위치를 구비하여, 조종실 도어가 열릴때마다 출입구에 에어커튼(air curtain)이 형성되도록 함에 따라 열손실이 방지되도록 하고 있다.As described above, the present invention device has a blower that rotates at a high speed by a motor on the entrance of the cockpit, and the cockpit door opening and closing part is provided with a switch for controlling the operation of the blower. As air curtains are formed, heat loss is prevented.
