본 발명은 냉장고에 관한 것으로, 더욱 상세하게는 냉장고 제상 운전 시 유 로 내부 표면에 이슬 맺힘 등으로 발생한 수분(물방울)이 유로 표면을 따라 흘러내릴 때, 유로 표면에 형성된 요철, 엠보싱, 경사면 구조 때문에, 수분이 송풍용 팬 모터 조립체 내부로 떨어지기 않게 되는 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, when moisture (drops) generated due to dew condensation on the inner surface of the flow path flows down along the flow path surface during the defrosting operation of the refrigerator, the unevenness, the embossing, and the inclined surface structure formed on the flow path surface. The present invention relates to a refrigerator in which moisture does not fall into the blowing fan motor assembly.

일반적으로 냉장고 냉기를 송풍하기 위해 냉장고 내부에 설치되는 냉기 송풍용 팬 모터 조립체는, 팬과 결합되는 회전자의 위치에 따라 인너 로터 타입과, 아우터 로터 타입 팬으로 구분될 수 있다.In general, the cold air blowing fan motor assembly installed inside the refrigerator to blow the refrigerator cold air may be divided into an inner rotor type and an outer rotor type fan according to the position of the rotor coupled with the fan.

인너 로터 타입 팬 모터 조립체는, 회전자가 고정자 내부에 설치된 구조를 갖으며, 아우터 로터 타입 팬 모터 조립체는, 회전자가 고정자 외부에 설치된 구조를 갖는다.The inner rotor type fan motor assembly has a structure in which the rotor is installed inside the stator, and the outer rotor type fan motor assembly has a structure in which the rotor is installed outside the stator.

최근 냉장고에는 냉기 송풍용 팬 모터 조립체로서, 냉장고 내 용적 확대를 위해 설치공간을 최소화하고 컴팩트 화할 수 있는 아우터 로터 타입 팬 모터 조립체가 많이 채용되고 있다.Recently, as a refrigerator air fan motor assembly for cooling air, many outer rotor type fan motor assemblies have been adopted for minimizing and compacting an installation space for expanding the volume of the refrigerator.

그러나, 아우터 로터 타입 팬 모터 조립체를 채용할 경우, 그 팬 모터 조립체가 쉬라우드(Shroud) 없이 냉장고 내벽에 형성된 냉기덕트의 유로에 직접 설치되기 때문에, 이러한 구조에서는 냉장고의 제상 운전 등의 경우, 냉장고의 냉기 유로에 맺혀진 수분(물방울)이 팬 모터 조립체 내부로 바로 떨어져서, 결국 팬 모터 조립체의 작동이 원활하지 못하게 되거나, 팬 모터 조립체의 수명이 단축되고, 심할 경우 팬 모터 조립체가 고장 나는 문제점이 있었다.However, when the outer rotor type fan motor assembly is adopted, the fan motor assembly is directly installed in the flow path of the cold air duct formed on the inner wall of the refrigerator without shrouds. Water (drops) formed in the cold air flow path of the fan flows directly into the fan motor assembly, which may cause the fan motor assembly to become inoperable, shorten the life of the fan motor assembly, or cause the fan motor assembly to malfunction. there was.

본 발명은, 냉장고 제상 모드와 같은 운전 시, 냉기덕트 유로 내부 표면에 이슬 맺힘 등으로 발생한 수분이 유로 표면을 따라 흘러내릴 때, 유로 표면에 형성된 요철, 엠보싱, 경사면과 같은 낙수 방지부 때문에 수분이 송풍용 팬 모터 조립체 내부로 떨어지기 않게 되어, 수분이 팬 모터 조립체 내부로 바로 떨어져서, 결국 팬 모터 조립체의 작동이 원활하지 못하게 되거나 팬 모터 조립체의 수명이 단축되고, 심할 경우 팬 모터 조립체가 고장 나는 문제점을 사전에 방지할 수 있는 냉장고를 제공함에 그 목적이 있다.According to the present invention, when water generated by dew condensation on the inner surface of the cold duct flow path flows along the flow path surface during operation such as a refrigerator defrosting mode, moisture is prevented due to falling water such as unevenness, embossing, and inclined surface formed on the flow path surface. Do not fall into the blower fan motor assembly, causing moisture to fall directly into the fan motor assembly, resulting in unstable operation of the fan motor assembly, shortened life of the fan motor assembly, or severe failure of the fan motor assembly. It is an object of the present invention to provide a refrigerator that can prevent problems in advance.

Here, 201 shows an air inlet, and the cold air blowing fan motor assembly 100 is an outer rotor type fan motor assembly.

참고적으로, 본 발명에 따른 냉기 송풍용 팬 모터 조립체(100)는, 냉기가 안내되도록 냉장고의 내벽에 형성된 냉기덕트(240) 일 측에 결합되며, 전면에 냉기 흡입구(111)가 형성되는 커버 플레이트(110)와, 상기 커버 플레이트(110)와 일정 간격을 두고, 상기 커버 플레이트(110)의 배면에 배치되는 모터 마운트 플레이트(120)와, 상기 모터 마운트 플레이트(120)에 장착되는 모터(미도시)와, 상기 모터의 회전축(미 도시)에 결합되는 팬(140)으로 구성된다.For reference, the cold air blowing fan motor assembly 100 according to the present invention is coupled to one side of the cold air duct 240 formed on the inner wall of the refrigerator to guide the cold air, the cover is formed with a cold air inlet 111 on the front The plate 110, the motor mount plate 120 disposed on the rear surface of the cover plate 110 at a predetermined distance from the cover plate 110, and a motor mounted on the motor mount plate 120 (not shown). H), and a fan 140 coupled to the rotating shaft (not shown) of the motor.

이와 같이 본 발명의 바람직한 실시 예에 따른 냉기 송풍용 팬 모터 조립체(100)는, 모터가 모터 마운트 플레이트(120)에 장착되고, 그 모터에 팬(140)이 회전 가능하게 결합되며, 팬(140)의 전면에는 커버 플레이트(110)가 위치되는 데, 이러한 각각의 부품이 모아져 하나의 단 품으로 구성된 제품, 일명 모듈(Module)로 형성된다. 따라서 냉기 송풍용 팬 모터 조립체의 컴팩트 화를 실현할 수 있고, 이 로 인하여 냉장고의 용적을 확대할 수 있는 것이다.As described above, in the cold air blower fan motor assembly 100 according to the preferred embodiment of the present invention, the motor is mounted on the motor mount plate 120, and the fan 140 is rotatably coupled to the motor, and the fan 140 At the front of the cover plate 110 is located, each of these parts is gathered to form a product consisting of a single unit, aka module (Module). Therefore, it is possible to realize the compactness of the fan motor assembly for the cold air blowing, thereby increasing the volume of the refrigerator.

상기 커버 플레이트(110)의 냉기 흡입구(111) 둘레에 상기 팬(140)으로의 원활한 냉기 흡입을 위해 오리피스(113)(Orifice)가 형성되어 있다.An orifice 113 is formed around the cold air inlet 111 of the cover plate 110 to smoothly suck the cold air to the fan 140.

본 발명의 특징으로, 도 2에 도시된 바와 같이, 상기 냉기 송풍용 팬 모터 조립체(100)의 모터 상방에 위치하는 유로(241)의 내벽 면에 구비되는 낙수 방지 부로서, 유로(241)의 내벽 면에 폭 방향으로 요철(251)이 형성되는 것이 바람직하다.As a feature of the present invention, as shown in Figure 2, as the fall prevention portion provided on the inner wall surface of the flow path 241 located above the motor of the cold air blowing fan motor assembly 100, It is preferable that the unevenness 251 is formed in the width direction on the inner wall surface.

이와 같이 구성된 본 발명의 제 1실시 예에 따른 냉장고의 작용을 설명한다.The operation of the refrigerator according to the first embodiment of the present invention configured as described above will be described.

사용자가 모터(미도시)에 전원을 인가하면, 모터의 회전자(미 도시)에 연결된 팬(140)이 회전을 하게 된다. 이때, 공기 흡입구(201)를 통해 흡입된 공기는 증발기(230)에 의해 냉기로 전환된 후, 팬(140)의 회전에 의해 냉기덕트(240)의 유로(241)를 통해 안내된다.When the user applies power to the motor (not shown), the fan 140 connected to the rotor (not shown) of the motor rotates. At this time, the air sucked through the air inlet 201 is converted to cold by the evaporator 230, and then guided through the flow path 241 of the cold air duct 240 by the rotation of the fan 140.

냉장고 제상 모드 운전 시, 냉기덕트(240)의 유로(241) 내부 표면에 이슬 맺힘 등으로 발생한 수분(물방울)이 유로(241) 표면을 따라 흘러내리게 되는 데, 이때, 유로(241) 내부 표면에 형성된 요철(251)의 표면의 불연속 형상 때문에 수분이 송풍용 팬 모터 조립체(100) 내부로 떨어지기 않게 된다. 따라서, 수분이 팬 모터 조립체 내부로 바로 떨어져서, 결국 팬 모터 조립체의 작동이 원활하지 못하게 되거나, 팬 모터 조립체의 수명이 단축되고, 심할 경우 팬 모터 조립체가 고장 나는 문제점을 사전에 방지할 수 있다.During operation of the refrigerator defrost mode, water (drops) generated by dew condensation on the inner surface of the flow path 241 of the cold air duct 240 flows down the surface of the flow path 241. Moisture does not fall into the fan motor assembly 100 for blowing due to the discontinuous shape of the surface of the formed irregularities 251. Therefore, moisture can fall directly into the fan motor assembly, resulting in unsatisfactory operation of the fan motor assembly, shorten the life of the fan motor assembly, and severely prevent the problem that the fan motor assembly fails.

또, 도 3은 본 발명의 제 2실시 예를 보인 사시도이다.3 is a perspective view showing a second embodiment of the present invention.

도 3에 도시된 바와 같이, 본 발명의 제 2실시 예에 있어서는, 낙수 방지 부의 다른 례로서, 냉기덕트(240)의 유로(241)의 내벽 면에 엠보싱(351)이 형성될 수도 있다.As shown in FIG. 3, in another embodiment of the present invention, an embossing 351 may be formed on the inner wall surface of the flow path 241 of the cold air duct 240 as another example of the fall prevention unit.

이때에도 냉장고 제상 모드 운전 시 유로 내부 표면에 이슬 맺힘 등으로 발생한 수분이 유로(241) 표면을 따라 흘러내리게 되는 데, 이때 상기 엠보싱(351)의 표면의 불연속 형상 때문에 수분이 송풍용 팬 모터 조립체(100) 내부로 떨어지기 않게 된다. 따라서, 수분(물방울)이 팬 모터 조립체(100) 내부로 바로 떨어져서, 결국 팬 모터 조립체의 작동이 원활하지 못하게 되거나 팬 모터 조립체의 수명이 단축되고, 심할 경우 팬 모터 조립체가 고장 나는 문제점을 사전에 방지할 수 있다.At this time, the moisture generated by dew condensation on the inner surface of the flow path flows down along the surface of the flow path 241 during operation of the refrigerator defrost mode. At this time, the moisture flows due to the discontinuous shape of the surface of the embossing 351. 100) It does not fall inside. Therefore, the water (drops) fall directly into the fan motor assembly 100, and thus, the fan motor assembly may not operate smoothly, or the life of the fan motor assembly may be shortened. You can prevent it.

또, 도 4는 본 발명의 제 3실시 예를 보인 사시도이다.4 is a perspective view showing a third embodiment of the present invention.

도 4에 도시된 바와 같이, 본 발명의 제 3실시 예에 있어서는, 낙수 방지 부의 다른 례로서, 냉기덕트(240)의 유로(241)의 내벽 면에 경사면(451)이 형성될 수도 있다.As shown in FIG. 4, in another embodiment of the present disclosure, an inclined surface 451 may be formed on an inner wall surface of the flow path 241 of the cold air duct 240 as another example of the fall prevention unit.

이때에도 냉장고 제상 모드 운전 시, 냉기덕트(240)의 유로(241) 내부 표면에 이슬 맺힘 등으로 발생한 수분이 유로 표면을 따라 흘러내리게 되는 데, 이때, 유로 표면에 형성된 경사면(451) 때문에 수분이 송풍용 팬 모터 조립체 내부로 떨어지기 않게 된다. 따라서, 수분이 팬 모터 조립체 내부로 바로 떨어져서, 결국 팬 모터 조립체의 작동이 원활하지 못하게 되거나 팬 모터 조립체의 수명이 단축되고, 심할 경우 팬 모터 조립체가 고장 나는 문제점을 사전에 방지할 수 있다.At this time, when the refrigerator defrost mode is operated, moisture generated due to dew condensation on the inner surface of the flow path 241 of the cold air duct 240 flows along the surface of the flow path. It does not fall into the blowing fan motor assembly. Therefore, moisture can fall directly into the fan motor assembly, resulting in unstable operation of the fan motor assembly or shortening of the life of the fan motor assembly.

이상에서 설명한 바와 같이, 본 발명에 의하면, 냉장고 제상 모드와 같은 운전 시 냉기덕트의 유로 내부 표면에 이슬 맺힘 등으로 발생한 수분이 유로 표면을 따라 흘러내리게 되는 데, 이때, 유로의 표면에 형성된 요철, 엠보싱, 경사면과 같은 낙수 방지부 때문에 수분이 송풍용 팬 모터 조립체 내부로 떨어지기 않게 된다.As described above, according to the present invention, moisture generated by dew condensation on the inner surface of the flow path of the cold air duct flows along the flow path surface during operation such as the refrigerator defrosting mode. Drop protection, such as embossing and inclined surfaces, prevents water from falling into the blower fan motor assembly.

따라서, 수분이 팬 모터 조립체 내부로 바로 떨어져서, 결국 팬 모터 조립체의 작동이 원활하지 못하게 되거나, 팬 모터 조립체의 수명이 단축되고, 심할 경우 팬 모터 조립체가 고장 나는 문제점을 사전에 방지할 수 있다.Therefore, moisture can fall directly into the fan motor assembly, resulting in unsatisfactory operation of the fan motor assembly, shorten the life of the fan motor assembly, and severely prevent the problem that the fan motor assembly fails.
