또한, 보조이동통로 사이를 서로 연결하는 순환이동통로가 형성됨으로써, 운전자의 손바닥에 의해 배출구의 일부가 막히더라도 막힌 배출구를 통과하여 조이스틱 바디의 외부로 배출되던 시원한 바람은 순환이동통로를 따라 조이스틱 바디 내부에서 순환하여 조이스틱 바디의 열을 더 흡수하게 되고, 순환하여 온도가 상승된 공기는 막히지 않은 타측 배출구로 배출됨에 따라, 운전자의 손바닥에 의해 배출구의 일부가 막히더라도 조이스틱 바디의 온도는 항상 낮게 유지되는 효과가 있다.In addition, the circulation movement path is formed between the auxiliary movement passages, so that even if a part of the outlet is blocked by the palm of the driver, cool wind discharged to the outside of the joystick body through the blocked outlet is the joystick body along the circulation movement passage. By circulating inside to absorb more heat from the joystick body, the temperature of the joystick body is always kept low even when a part of the outlet is blocked by the palm of the driver as the circulated air is discharged to the other outlet which is not blocked. It is effective.
또한, 조이스틱 바디의 외주면에 배출구를 서로 연통시키는 외주공기통로가 형성됨으로써, 운전자가 조이스틱 바디를 파지하더라도 손바닥이 감싸는 배출구가 막히지 않게 되며, 배출구를 통해 배출된 시원한 바람은 외주공기통로를 따라 흐르는 과정에서 손바닥의 열을 직접 흡수하게 됨으로써, 땀의 발생을 방지하거나 땀이 발생되더라도 신속하게 증발시키며, 이에 따라 운전자는 조이스틱 바디를 파지한 상태에서 손바닥과 조이스틱 바디의 사이로 시원한 바람이 통과하는 상쾌한 느낌을 받으며 조이스틱을 조작할 수 있는 효과가 있다.In addition, an outer air passage is formed on the outer circumferential surface of the joystick body so that the outlets communicate with each other, so that the outlet surrounding the palms is not blocked even when the driver grips the joystick body. By absorbing the heat directly from the palm of the hand, it prevents the occurrence of sweat or quickly evaporates even when sweat occurs, so that the driver feels the refreshing feeling of cool wind passing between the palm and the joystick body while holding the joystick body. The joystick can be manipulated.

본 발명의 바람직한 일실시예에 의한 쿨링기능을 가지는 건설기계용 조이스틱(1)의 적용상태를 살펴보면 다음과 같다.Looking at the application state of the construction machine joystick (1) having a cooling function according to an embodiment of the present invention.
도 1 내지 도 3을 참조하면, 상술한 바와 같이 운전자가 콘솔박스(2)에 구비된 온/오프 스위치(21)를 조작하여 쿨링팬(20)을 작동시키면, 에어컨 모듈(미도시)로부터 유입되는 시원한 바람은 메인공기통로(30)를 통해 조이스틱 바디(10)의 하부에서 상부로 흐르게 되고, 메인공기통로(30)의 길이방향을 따라 다단으로 형성되고 레이디얼 방향을 따라 다수 개로 형성된 보조공기통로(40)를 통과하여 배출구(11)를 통해 조이스틱 바디(10)의 외부로 배출된다.1 to 3, when the driver operates the cooling fan 20 by operating the on / off switch 21 provided in the console box 2, the airflow module (not shown) flows in from the air conditioner module (not shown).

상술한 바와 같이, 시원한 바람이 메인공기통로(30)와 다수의 보조공기통로(40)를 통해 조이스틱 바디(10)의 내부에서 흐르는 과정에서 시원한 바람은 메인공기통로(30)와 다수의 보조공기통로(40)의 열을 흡수하여 조이스틱 바디(10)의 외부로 배출되며, 이에 따라 지속적으로 열에너지의 손실이 발생하게 되는 조이스틱 바디(10)는 에어컨 모듈(미도시)의 온도설정에 따라 온도가 일정수준까지 하강하여 냉각된 상태를 유지하게 된다.As described above, in the course of the cool wind flowing inside the joystick body 10 through the main air passage 30 and the plurality of auxiliary air passages 40, the cool wind is the main air passage 30 and the plurality of auxiliary air passages. Absorbs heat from the furnace 40 and discharges it to the outside of the joystick body 10. Accordingly, the joystick body 10, which continuously loses heat energy, has a temperature according to a temperature setting of an air conditioning module (not shown). Lowered to a certain level to maintain a cooled state.
한편, 운전자가 조이스틱 바디(10)를 파지하게 되면, 손바닥(H)의 열기는 지속적으로 열손실이 발생하고 있는 조이스틱 바디(10)로 전달되어 운전자의 손바닥(H)은 시원한 상태를 유지하게 되고, 이에 따라 운전자의 손바닥(H)은 땀의 발생이 억제되어 조이스틱(1)의 조작성이 향상되고, 운전자는 상쾌한 느낌을 받으며 조이스틱(1)을 조작할 수 있게 된다.On the other hand, when the driver grips the joystick body 10, the heat of the palm (H) is transmitted to the joystick body 10 that is continuously generating heat loss to keep the palm of the driver (H) cool state Accordingly, the palm of the driver H is suppressed from the generation of sweat, so that the operability of the joystick 1 is improved, and the driver can operate the joystick 1 while feeling refreshed.
본 발명의 바람직한 다른 실시예에 의한 쿨링기능을 가지는 건설기계용 조이스틱(1)은 보조공기통로(40)의 사이에 순환공기통로(60)가 형성되어 시원한 바람이 조이스틱 바디(10)의 내부에서 순환하게 된다.Joystick (1) for construction machinery having a cooling function according to another preferred embodiment of the present invention is a circulation air passage 60 is formed between the auxiliary air passage 40 so that cool wind is inside the joystick body 10 It will cycle.
도 4는 본 발명의 바람직한 다른 실시예에 의한 쿨링기능을 가지는 건설기계용 조이스틱의 사용상태를 나타내는 횡단면도이다.Figure 4 is a cross-sectional view showing a state of use of the joystick for construction machinery having a cooling function according to another embodiment of the present invention.
도 4를 참조하면, 메인공기통로(30)의 레이디얼 방향으로 형성되는 보조공기통로(40)의 사이에 순환공기통로(60)가 형성된다.Referring to FIG. 4, a circulating air passage 60 is formed between the auxiliary air passages 40 formed in the radial direction of the main air passage 30.
순환공기통로(60)는 보조공기통로(40)의 사이에 원주방향으로 형성되어 일측 보조공기통로(40)를 따라서 흐르는 시원한 공기가 우회하여 타측 보조공기통로(40)로 유입되는 관로를 형성하며, 이에 따라 조이스틱 바디(10)의 내부에서 흐르는 시원한 공기는 열을 흡수하는 면적이 증가하게 되어 조이스틱 바디(10)의 냉각속도가 향상된다.The circulating air passage 60 is formed in the circumferential direction between the auxiliary air passages 40 so as to bypass the cool air flowing along one side of the auxiliary air passage 40 to form a passage flowing into the other side of the auxiliary air passage 40. Accordingly, the cool air flowing in the joystick body 10 increases the area for absorbing heat, thereby improving the cooling rate of the joystick body 10.
또한, 운전자가 조이스틱 바디(10)를 파지한 경우에 운전자의 손바닥(H)에 의해 다수의 배출구(11)가 폐쇄되고, 보조공기통로(40)를 따라 폐쇄된 배출구(11)측으로 흐르던 시원한 공기는 순환공기통로(60)를 따라 우회하여 개방된 배출구(11)측으로 흐르거나 메인공기통로(30)측으로 우회하여 조이스틱 바디(10)의 내부에서 순환하게 된다.In addition, when the driver grips the joystick body 10, the plurality of outlets 11 are closed by the palm of the driver H, and the cool air flowing toward the closed outlet 11 along the auxiliary air passage 40. The bypass flows along the circulation air passage 60 to the open outlet 11 side or bypasses the main air passage 30 to circulate inside the joystick body 10.
상술한 바와 같이, 바람의 우회 및 순환에 의해 시원한 공기가 접촉하는 메인공기통로(30), 보조공기통로(40) 및 순환공기통로(60)의 면적은 증가하게 되고, 시원한 공기는 운전자가 조이스틱(1)을 파지하지 않은 상태보다 더욱 원활한 열교환이 이루어지게 되며, 이에 따라 운전자의 손바닥(H)은 땀의 발생이 보다 효과적으로 억제되는 것이다.As described above, the area of the main air passage 30, the auxiliary air passage 40 and the circulating air passage 60 to which the cool air contacts by the bypass and circulation of the wind is increased, the cool air is the joystick of the driver The heat exchange is made more smoothly than the state of not holding (1), and thus the palm of the driver H is more effectively suppressed from the generation of sweat.
한편, 순환공기통로(60)는 메인공기통로(30)의 길이방향으로 형성되어 시원한 공기가 상,하 방향으로 우회 및 순환되도록 하는 것도 가능하다.On the other hand, the circulation air passage 60 is formed in the longitudinal direction of the main air passage 30 it is possible to allow the cool air to bypass and circulate in the vertical direction.
본 발명의 바람직한 또 다른 실시예에 의한 쿨링기능을 가지는 건설기계용 조이스틱(1)은 조이스틱 바디(10)의 외주면에 배출구(11)를 서로 연통시키는 외주공기통로(70)가 형성되는 것도 가능하다.In the joystick 1 for construction machinery having a cooling function according to another preferred embodiment of the present invention, an outer circumferential air passage 70 may be formed on the outer circumferential surface of the joystick body 10 to communicate the outlet 11 with each other. .
도 5는 본 발명의 바람직한 또 다른 실시예에 의한 쿨링기능을 가지는 건설기계용 조이스틱의 측면도이고, 도 6은 본 발명의 바람직한 또 다른 실시예에 의한 쿨링기능을 가지는 건설기계용 조이스틱의 사용상태를 나타내는 횡단면도이다.5 is a side view of a joystick for construction machinery having a cooling function according to another preferred embodiment of the present invention, Figure 6 is a state of use of the joystick for construction machinery having a cooling function according to another preferred embodiment of the present invention It is a cross-sectional view showing.
도 5 및 도 6을 참조하면, 메인공기통로(30)를 따라 레이디얼 방향으로 형성되는 보조공기통로(40)의 배출구(11)를 조이스틱 바디(10)의 외주면에서 서로 연통시키는 환형의 외주공기통로(70)가 형성될 수 있다.5 and 6, an annular outer cylinder for communicating the outlet 11 of the auxiliary air passage 40 formed in the radial direction along the main air passage 30 on the outer circumferential surface of the joystick body 10. The furnace 70 may be formed.
외주공기통로(70)가 형성되면, 배출구(11)는 조이스틱 바디(10)의 횡방향을 따라서 환형의 홈 형태로 형성되는 외주공기통로(70)에 의해 운전자가 조이스틱 바디(10)를 파지하더라도 폐쇄되지 않고 개방된 상태를 유지하게 된다.When the outer periphery air passage 70 is formed, the outlet 11 is formed even if the driver grips the joystick body 10 by the outer periphery air passage 70 formed in an annular groove shape along the transverse direction of the joystick body 10. It will remain open without being closed.
즉, 외주공기통로(70)와 운전자의 손바닥(H) 사이에는 공기가 흐를 수 있는 유로가 형성되고, 이에 따라 배출구(11)를 통해 배출되는 시원한 바람은 외주공기통로(70)를 따라 흐르면서 운전자의 손바닥(H)에서 발생되는 열을 직접 흡수하여 조이스틱 바디(10)를 파지한 손바닥(H)의 가장자리를 통해 외부로 배출되는 것이다.That is, a flow path through which air flows is formed between the outer air passage 70 and the palm of the driver H, and thus cool wind discharged through the outlet 11 flows along the outer air passage 70. By directly absorbing the heat generated from the palm (H) of the joystick body 10 is discharged to the outside through the edge of the palm (H) holding the body.
이에 따라, 조이스틱 바디(10)를 파지하고 있는 운전자의 손바닥(H)은 메인공기통로(30) 및 보조공기통로(40)를 흐르는 시원한 바람에 의해 온도가 낮게 유지되고 있는 조이스틱 바디(10)를 통해 1차적으로 열기가 흡수되고, 외주공기통로(70)의 개방된 외측을 막고 있는 손바닥(H)은 외주공기통로(70)를 따라서 흐르는 시원한 바람과 직접적으로 열교환이 진행되므로 손바닥(H)의 땀 발생이 보다 효율적으로 억제되며, 운전자는 손바닥(H)을 통해 시원한 바람이 흐르는 상쾌한 느낌을 받는 상태에서 조이스틱(1)을 조작할 수 있게 된다.Accordingly, the palm of the driver H holding the joystick body 10 may move the joystick body 10 whose temperature is kept low by cool wind flowing through the main air passage 30 and the auxiliary air passage 40. Heat is primarily absorbed through the palm, and the palm H blocking the open outside of the outer air passage 70 directly exchanges heat with cool wind flowing along the outer air passage 70. The occurrence of sweat is more effectively suppressed, and the driver can operate the joystick 1 in a state in which a cool wind flows through the palm H.
이와 같이 본 발명의 상세한 설명에서는 구체적인 실시 예에 관한 방법을 설명을 하였으나, 본 발명의 범주에서 벗어나지 않는 한도 내에서 여러 가지 변형이 가능함은 물론이다. 그러므로 본 발명의 범위는 설명된 실시 예에 국한되어 정해져서는 안되며, 후술하는 특허청구범위뿐만 아니라 이 청구범위와 균등한 것들에 의해 정해져야 한다.As described above, the method of the specific embodiment has been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims below and equivalents thereof.
전술한 바와 같이 본 발명의 실시 예에 따른 쿨링기능을 가지는 건설기계용 조이스틱은, 조이스틱 바디의 내부에 에어컨 모듈의 시원한 바람이 유입되는 메인이동통로를 형성하고, 메인이동통로와 연통되고 조이스틱 바디의 외주면측으로 형성되어 시원한 바람이 유출되는 보조이동통로를 형성함으로써, 운전자의 손바닥으로부터 전달되는 열기를 조이스틱 바디가 빠르게 흡수하여 손바닥의 온도를 지속적으로 낮게 유지하며, 손바닥에서 땀이 발생되더라도 보조이동통로의 단부에 형성된 배출구로부터 배출되는 시원한 바람이 손바닥과 조이스틱 바디의 사이에 공급되어 땀을 증발시킴으로써, 운전자의 손바닥이 조이스틱 바디로부터 미끄러지지 않고 운전자는 상쾌한 촉감을 유지한 상태에서 조이스틱을 조작할 수 있는 것이다.As described above, the joystick for construction machinery having a cooling function according to an embodiment of the present invention forms a main movement passage through which cool air of an air conditioner module flows into the joystick body, and communicates with the main movement passage to form a main movement passage of the joystick body. Formed on the outer circumferential side to form an auxiliary movement passage through which cool wind flows out, the joystick body quickly absorbs the heat transferred from the driver's palm and keeps the temperature of the palm constantly low, even if sweat occurs in the palm of the auxiliary movement passage. The cool wind discharged from the discharge port formed at the end is supplied between the palm and the joystick body to evaporate sweat, so that the driver's palm does not slip from the joystick body and the driver can operate the joystick while maintaining a refreshing touch.
