Description

냉장고의 냉기순환팬 고정구조Cold air circulation fan fixing structure of refrigerator

본 고안은 냉장고의 냉기순환팬에 관한 것으로, 더욱 상세하게는 냉기순환팬을 설정된 위치에 고정시킬 수 있도록 하여 냉각 성능을 향상시킬 수 있도록 한 냉장고의 냉기순환팬 고정구조에 관한 것이다.The present invention relates to a cold air circulation fan of a refrigerator, and more particularly, to a cold air circulation fan fixing structure to improve the cooling performance by fixing the cold air circulation fan in a predetermined position.

일반적으로 냉장고는 도 1에서 보이는 바와같이 고내 온도를 일정하게 유지하기 위하여 고내 온도에 따라 온,오프 제어되는 압축기(1)와 도어(2)의 개폐시 도어스위치(미도시)의 온,오프 작동에 연동하여 제어되는 팬 모터(3)를 구동원으로 하여 냉기순환팬(4)이 작동하면서 증발기(5)를 통해 냉각된 냉기를 고내에 공급하는 것으로, 증발기(5)는 증발기 리어 커버(6)를 통해 고내 안쪽에 형성된 냉기실(7)에 장착되며, 증발기 리어 커버(6)에 장착된 냉기순환팬(3)에 의해 토출되는 냉기는 증발기 프런트 커버(8)의 각 토출공(미도시)을 통하여 고내로 토출되고, 고내로 토출된 냉기는 고내를 순환하면서 고내의 온도를 낮추고 난 후 증발기(5)로 다시 귀환된다.Generally, the refrigerator operates on and off of a door switch (not shown) when opening and closing the compressor 1 and the door 2 that are controlled on and off according to the internal temperature in order to maintain a constant internal temperature as shown in FIG. 1. By supplying cool air cooled through the evaporator 5 while the cold air circulation fan 4 is operated as a driving source controlled in conjunction with the fan motor 3, the evaporator 5 is an evaporator rear cover 6. The cold air discharged by the cold air circulation fan 3 mounted on the cold air chamber 7 formed inside the inside of the refrigerator and mounted on the rear cover 6 of the evaporator (not shown) The cold air discharged into the inside of the refrigerator is discharged to the inside of the refrigerator, and the temperature of the inside of the refrigerator is lowered while circulating the inside of the refrigerator.

냉기순환팬(4)과 팬 모터(3)의 설치 상태를 좀더 상세히 설명하면, 도 2와 도 3에서 보이는 바와 같이, 증발기 리어 커버(6)의 상측 중앙부에 천공된 벨 마우스(6a)에는 냉기순환팬(4)이 위치되며, 냉기순환팬(4)의 후방측에는 팬 모터(3)가 설치되고, 냉기순환팬(4)의 중앙부에는 팬 모터(3)의 구동축(3a)이 끼워지는 축공(4a)이 구비된다.The installation state of the cold air circulation fan 4 and the fan motor 3 will be described in more detail. As shown in FIGS. 2 and 3, the bell mouth 6a drilled in the upper center portion of the evaporator rear cover 6 has cold air. The circulation fan 4 is located, the fan motor (3) is installed on the rear side of the cold air circulation fan (4), the shaft hole in which the drive shaft (3a) of the fan motor (3) is fitted in the center of the cold air circulation fan (4) (4a) is provided.

팬 모터(3)는 케이스(미도시)의 내부에 고정 및 받침대(미도시)를 통해에 고정된다.The fan motor 3 is fixed to the inside of the case (not shown) and through a pedestal (not shown).

도면중 미설명 부호 9는 증발기 프런트 커버이다.In the figure, reference numeral 9 denotes an evaporator front cover.

이와 같이 구성된 종래 냉기순환팬에 의한 작용을 설명하면, 팬 모터(3)에 전원이 인가되면 냉기순환팬(4)이 구동축(3a)을 통해 전달받은 회전력에 의해 일방향으로 회전하면서 증발기(5)를 통해 냉각된 냉기실(7)내의 냉기를 흡입하며, 이 냉기는 증발기 리어 커버(6)의 벨 마우스(6a)를 통해 각 커버(6)(9)의 사이 공간으로 토출되고, 각 커버(6)(9) 사이의 공간을 순환하면서 일부는 중간격을 통해 냉장실쪽으로 토출되며, 일부는 냉동실 증발기 프런트 커버(6)의 토출공(미도시)을 통해 고내로 토출된다.Referring to the operation by the conventional cold air circulation fan configured as described above, when power is applied to the fan motor 3, the cold air circulation fan 4 rotates in one direction by the rotational force transmitted through the drive shaft 3a and the evaporator 5. The cold air is sucked in the cold air chamber 7 cooled through the air, and the cold air is discharged into the space between the covers 6 and 9 through the bell mouth 6a of the rear cover 6 of the evaporator, and each cover ( 6) (9) while circulating the space between the part is discharged into the refrigerating chamber through the intermediate space, part is discharged into the chamber through the discharge hole (not shown) of the freezer compartment evaporator front cover (6).

그러나, 종래 팬 모터의 구동축에 냉기순환팬을 고정함에 있어서, 냉기순환팬(4)을 팬 모터(3)의 구동축(3a)에 수작업으로 고정하며, 이 작업시 냉기순환팬(4)의 설치 위치를 정확하게 알 수 없기 때문에 작업자는 눈대중으로 냉기순환팬(4)을 고정하여 냉기순환팬(4)의 고정 위치가 설정된 위치와 다르게 되었다. 즉, 벨 마우스(6a)내의 설정위치에 고정되지 못하고, 증발기 리어 커버(6)의 전방이나 후방에 위치된다.However, in fixing the cold air circulation fan to the drive shaft of the conventional fan motor, the cold air circulation fan 4 is manually fixed to the drive shaft 3a of the fan motor 3, and the cold air circulation fan 4 is installed during this operation. Since the position is not known accurately, the operator fixes the cold air circulation fan 4 to the eye mass and the fixed position of the cold air circulation fan 4 is different from the set position. That is, it is not fixed to the set position in the bell mouth 6a, but is located in front of or behind the evaporator rear cover 6.

따라서, 냉기순환팬(4)이 설정된 위치에 설치되지 않으면 고내에 토출되는 냉기의 양이 적어지기 때문에 고내의 신선도를 유지하지 못하게 되며, 또한, 신선도 유지를 위해 설정양 만큼의 냉기를 토출시키기 위해서는 냉기순환팬(4)의 운전율이 높아지는 문제점이 있었다.Therefore, if the cold air circulation fan 4 is not installed at the set position, the amount of cold air discharged in the refrigerator is reduced, so that the freshness in the refrigerator cannot be maintained, and in order to discharge the cold air as much as the set amount to maintain the freshness, There was a problem that the operation rate of the cold air circulation fan (4) increases.

본 고안은 상술한 문제점을 해소하기 위해 안출된 것으로, 냉기순환팬을 팬 모터 구동축의 설정된 위치에 고정시켜 냉기순환팬을 통해 토출되는 냉기가 설정된 양을 유지할 수 있도록 함으로써 고내의 신선도 유지 및 소비 전력을 감소시킬 수 있도록 한 냉장고의 냉기순환팬 고정구조를 제공하려는데 그 목적이 있다.The present invention has been made to solve the above problems, by fixing the cold air circulation fan to the set position of the fan motor drive shaft to maintain the set amount of cold air discharged through the cold air circulation fan to maintain the freshness in the high power It is an object of the present invention to provide a fixed structure of a cold air circulation fan of a refrigerator so as to reduce the size of the refrigerator.

이하 첨부된 도면에 의거하여 본 고안에 의한 바람직한 실시예를 상세히 설명하면 다음과 같다. 설명의 편의를 위해 종래 기술과 동일하게 구성되는 구성부재에 대해서는 동일한 부재번호를 부여한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. For convenience of description, the same member numbers are assigned to constituent members configured in the same manner as in the prior art.

도 4는 본 고안에 의한 실시예에 적용된 기준위치설정용수단을 도시한 팬 모터의 사시도이며, 도 5는 본 고안에 의한 실시예를 보인 측면도이다.Figure 4 is a perspective view of a fan motor showing a reference positioning means applied to an embodiment according to the present invention, Figure 5 is a side view showing an embodiment according to the present invention.

이에 도시된 바와 같이, 본 고안 냉기순환팬 고정구조는, 팬 모터 구동축(3a)의 소정 위치에는 상하로 관통하는 핀공(11)을 천공하며, 핀공(11)에는 그 양단이 구동축(3a)의 외부로 돌출되도록 소정의 길이를 갖는 핀(10)을 압입 고정하고, 냉기순환팬(4)의 축공(4a)에는 구동축(3a)을 결합하되, 냉기순환팬(4)과 핀(10)이 밀착되도록 한다.As shown in the drawing, the present invention cold air circulation fan fixing structure drills a pin hole 11 penetrating up and down at a predetermined position of the fan motor drive shaft 3a, and both ends of the pin hole 11 are connected to the drive shaft 3a. The pin 10 having a predetermined length is press-fitted to protrude to the outside, and the driving shaft 3a is coupled to the shaft hole 4a of the cold air circulation fan 4, but the cold air circulation fan 4 and the fin 10 are Make sure they are in close contact.

핀(10)의 위치는 냉기순환팬(4)의 설정위치에 결합된다. 이때, 설정위치 즉 핀(10)이 결합되는 핀공(11)의 천공위치는 냉기순환팬(4)이 벨 마우스(6a)의 내부에서 회전되기 위한 위치로서, 냉기순환팬(4)의 상부팬의 선단과 하부팬의 후단 사이의 간격을 L이라 할 때, 이와 같이 벨 마우스(6a)내에 위치하는 하부팬의 후단에서 내측방향으로 D만큼 이격된 위치인 것이다.The position of the pin 10 is coupled to the set position of the cold air circulation fan (4). At this time, the setting position, that is, the drilling position of the pin hole 11 to which the pin 10 is coupled is a position for the cold air circulation fan 4 to rotate inside the bell mouth 6a, and an upper fan of the cold air circulation fan 4. When the distance between the front end and the rear end of the lower fan is referred to as L, it is a position spaced inward from the rear end of the lower fan located in the bell mouse 6a by D in this way.

이처럼 설정된 D의 위치에 핀공(11)을 형성하여 핀(10)을 삽입한 상태에서 냉기순환팬(4)의 축공(4a)을 모터의 축(3a)에 삽입하면 용이하게 냉기순환팬(4)이 벨 마우스(6)의 내부에 위치하도록 결합되는 것이다.When the pin hole 11 is formed at the position D set as described above, and the shaft hole 4a of the cold air circulation fan 4 is inserted into the shaft 3a of the motor in the state where the pin 10 is inserted, the cold air circulation fan 4 is easily formed. ) Is coupled to be located inside the bell mouse (6).

팬 모터(3)는 케이스(미도시)의 내부에 장착되며, 케이스는 받침대(미도시)를 통해 설치된다.The fan motor 3 is mounted inside the case (not shown), and the case is installed through a pedestal (not shown).

이와 같이 구성된 본 고안에 의한 실시예의 작용은 종래와 동일하게 팬 모터(3)에 전원이 인가되면 냉기순환팬(4)이 구동축(3a)과 일체로 회전하면서 증발기를 통해 냉각된 냉기를 흡입하여 고내로 토출시킨다.When the power is applied to the fan motor 3 as in the prior art, the cold air circulation fan 4 rotates integrally with the drive shaft 3a and sucks the cold air cooled through the evaporator. Discharge into the chamber.

따라서, 냉기순환팬(4)을 팬 모터(3)의 구동축(3a)에 결합할 때 작업자는 종래와 같이 눈대중으로 냉기순환팬의 위치를 결정하지 않고, 냉기순환팬(4)이 핀(10)과 밀착되도록 결합됨으로써 냉기순환팬(4)을 설정된 위치에 고정시킬 수 있게 된다.Therefore, when coupling the cold air circulation fan 4 to the drive shaft 3a of the fan motor 3, the operator does not determine the position of the cold air circulation fan in the eye as in the prior art, and the cold air circulation fan 4 is the pin 10 By being in close contact with the) it is possible to fix the cold air circulation fan (4) in a set position.

이상에서 살펴본 바와같이, 본 고안에 의한 냉기순환팬 고정구조에 의하면, 냉기순환팬이 설정된 위치에 고정되어 팬 모터를 구동원으로 하여 회전하면서 고내로 토출시키는 냉기가 설정된 양을 유지하게 됨에 따라 고내의 신선도를 유지할 수 있음은 물론, 냉기순환팬의 구동을 위한 소비전력을 감소시킬 수 있는 효과가 있다. 여기서 냉기순환팬이 팬 모터의 축에 고정되는 위치는 결합되는 벨 마우스의 내부 공간의 크기에 따라 가변적이나, 냉기순환팬이 벨 마우스의 내부에 위치할 수 있는 조건을 만족하면 어느 위치이거나 가능하다 할 것이다.As described above, according to the cold air circulation fan fixing structure according to the present invention, the cold air circulation fan is fixed to the set position, the rotation of the fan motor as a drive source while maintaining the set amount of cold air discharged into the refrigerator while maintaining the set amount As well as maintaining the freshness, there is an effect that can reduce the power consumption for driving the cold air circulation fan. Here, the position where the cold air circulation fan is fixed to the shaft of the fan motor is variable depending on the size of the inner space of the bell mouse to be coupled, but may be any position as long as the condition that the cold air circulation fan is located inside the bell mouse is satisfied. something to do.
