먼지 유입 방지 장치Dust inflow prevention device
본 발명은 외부 공기를 유입시켜 발열체를 냉각시키는 제품인 냉장고나 컴퓨터 등에 채용되어 해당 제품의 내부로 먼지가 유입되는 것을 방지하기 위한 먼지 유입 방지 장지에 관한 것이다.The present invention relates to a dust inflow prevention device used in refrigerators and computers, which are products that cool the heating element by introducing outside air, to prevent dust from entering the product.
일반적으로, 냉각팬을 이용하여 외부 공기를 유입시켜 내부의 발열체를 냉각시키는 제품으로는 냉장고나 컴퓨터 등이 알려져 있다. 이 중 컴퓨터는, 냉각팬의 구동으로 외부의 공기가 유입되면서 본체의 내부에 마련된 전원장치나 CPU 등을 냉각시키게 되는데, 먼지가 함께 유입되면서 먼지의 축적으로 냉각 효율이 떨어지는 문제와 CPU 등의 수명이 단축되는 문제 등이 있다.In general, refrigerators and computers are known products that cool internal heating elements by introducing external air using a cooling fan. Among these, the computer cools the power supply or CPU provided inside the main body as external air flows in through the operation of the cooling fan. As dust flows in, the cooling efficiency decreases due to the accumulation of dust and the lifespan of the CPU decreases. There is a problem with this being shortened.

기존의 냉장고는, 도 1 및 도 2에 도시된 바와 같이, 소정의 크기로 형성된 본체(10), 본체(10)의 내부에 마련되는 냉동실(F)과 냉장실(R) 등의 보관실, 본체(10)의 하부 후면에 구비되는 기계실(M)을 포함한다. 또한, 기계실(M)에는 열을 발생시키는 압축기(50)와 응축기(60)가 장착되고, 이 압축기(50)와 응축기(60)의 측부에 공기의 유동을 발생시켜 기계실 내부를 냉각시키는 냉각팬(70)이 구비되며, 그리고 본체(10)의 배면에는 기계실(M)을 덮는 기계실 커버(90)가 구비된다. 기계실 커버(90)는 소정의 면적을 갖는 평판 형상을 가지고, 이의 일 측에는 외부의 공기를 유입시키기 위한 복수의 공기 유입공((91)이 형성되며, 그리고 이의 타 측에는 공기를 유출시키기 위한 복수의 공기 유출공(92)이 형성된다. 참고로, 냉장고는, 도어의 위치나 수에 따라 상하부에 개폐 도어를 각각 가지는 일반 타입 냉장고와, 하나의 개폐 도어를 가지는 단문 타입 냉장고와, 좌우에 개폐 도어를 각각 가지는 양문 타입 냉장고 등이 알려져 있으며, 도 1에는 이 중 일반 타입 냉장고를 참고로 도시하고 있다.As shown in Figures 1 and 2, the existing refrigerator has a main body 10 formed of a predetermined size, a storage compartment such as a freezer compartment (F) and a refrigerator compartment (R) provided inside the main body 10, and the main body ( It includes a machine room (M) provided at the lower rear of 10). In addition, the machine room (M) is equipped with a compressor 50 and a condenser 60 that generate heat, and a cooling fan that generates air flow on the sides of the compressor 50 and the condenser 60 to cool the inside of the machine room. (70) is provided, and a machine room cover 90 is provided on the rear of the main body 10 to cover the machine room (M). The machine room cover 90 has a flat plate shape with a predetermined area, a plurality of air inlet holes (91) are formed on one side thereof for introducing external air, and a plurality of air inlet holes 91 are formed on the other side thereof for letting air out. An air outflow hole 92 is formed. For reference, the refrigerator includes a general type refrigerator having opening and closing doors at the top and bottom depending on the position or number of doors, a single door type refrigerator having one opening and closing door, and an opening and closing door on the left and right. Double-door type refrigerators each having a are known, and Figure 1 shows a general type refrigerator among them for reference.
이러한 기존의 냉장고는, 전원이 공급되어 운전이 시작되면 냉동 사이클이 작동함에 따라 보관실에 마련된 증발기(30)에서 냉기를 발생시키게 될 뿐만 아니라 기계실에 마련된 압축기(50)와 응축기(60)에서 열을 발생시키게 된다. 특히, 기계실(M)에 마련된 압축기(50)와 응축기(60)를 냉각시키 위해 냉각팬(70)이 팬모터(80)에 의해 구동하게 되고, 냉각팬(70)의 회전으로 외부의 공기가 기계실 커버(90)의 공기 유입공(91)을 통해 기계실(M)의 내부로 유입되고 기계실(M)의 내부를 거친 후 공기 유출공(92)을 통해 외부로 유출된다.In such a conventional refrigerator, when power is supplied and operation begins, the refrigeration cycle operates and not only generates cold air from the evaporator 30 provided in the storage room, but also generates heat from the compressor 50 and condenser 60 provided in the machine room. It occurs. In particular, the cooling fan 70 is driven by the fan motor 80 to cool the compressor 50 and the condenser 60 provided in the machine room (M), and the rotation of the cooling fan 70 causes external air to It flows into the inside of the machine room (M) through the air inlet hole (91) of the machine room cover (90), passes through the inside of the machine room (M), and then flows out to the outside through the air outlet hole (92).
하지만, 기존의 냉장고는, 외부의 공기가 기계실 커버의 공기 유입공을 통해 기계실로 유입되는 기술구성을 제공하므로, 외부의 공기가 유입되는 동안 이에 포함된 먼지가 함께 유입되면서 기계실에 점차적으로 축적되는 문제가 있고, 이렇게 축적된 먼지로 인해, 화재가 발생되는 문제와 냉각 효율이 떨어지는 문제와 압축기의 수명이 단축되는 문제 등이 있다.However, the existing refrigerator provides a technical configuration in which external air flows into the machine room through the air inlet hole in the machine room cover, so while the outside air flows in, the dust contained in it flows in and gradually accumulates in the machine room.

본 발명의 일 실시예에 따른 먼지 유입 방지 장치(100)는, 도 3 내지 도 6에 도시된 바와 같이, 외부 공기를 유입시켜 발열체를 냉각시키는 제품(냉장고나 컴퓨터 등)에 장착되어 사용되는 먼지 유입 방지 장치로, 필터 케이스(110)와, 먼지 필터(120)와, 그리고 공기 안내부(130)를 포함한다. 이하, 도 3 내지 도 6을 계속 참조하여, 각 구성요소에 대해 상세히 설명한다.As shown in FIGS. 3 to 6, the dust inflow prevention device 100 according to an embodiment of the present invention is installed on a product (refrigerator, computer, etc.) that cools the heating element by introducing external air to prevent dust. The inflow prevention device includes a filter case 110, a dust filter 120, and an air guide unit 130. Hereinafter, with continued reference to FIGS. 3 to 6, each component will be described in detail.
필터 케이스(110)는, 본 발명의 먼지 유입 방지 장치(100)의 외장을 이루는 구성요소이다. 이러한 필터 케이스(110)는, 도 3에 도시된 바와 같이, 제품(90)에 장착될 수 있으며, 먼지 필터(120)를 제품(90)에 마련된 공기 유입공(91)에 대면시킬 수 있다. 예를 들어, 필터 케이스(110)는, 도 4에 도시된 바와 같이, 대략 직육면체 형상을 가질 수 있다.The filter case 110 is a component that forms the exterior of the dust inflow prevention device 100 of the present invention. This filter case 110 can be mounted on the product 90, as shown in FIG. 3, and the dust filter 120 can be placed against the air inlet hole 91 provided in the product 90. For example, the filter case 110 may have a substantially rectangular parallelepiped shape, as shown in FIG. 4 .
먼지 필터(120)는, 외기가 제품의 내부로 유입되기에 앞서 외기에 포함된 먼지를 실질적으로 여과시키는 구성요소이다. 이러한 먼지 필터(120)는, 도 3 및 도 5에 도시된 바와 같이, 필터 케이스(110)의 내부에 구비될 수 있다. 예를 들어, 먼지 필터(120)는, 일 예로 먼지만 거르도록 부직포 등으로 이루어진 프리 필터만으로 이루어질 수도 있고, 다른 예로 프리 필터와 탈취 기능을 겸하는 카본 필터를 포함할 수도 있다.The dust filter 120 is a component that substantially filters dust contained in the outside air before the outside air flows into the product. This dust filter 120 may be provided inside the filter case 110, as shown in FIGS. 3 and 5. For example, the dust filter 120 may be comprised of only a pre-filter made of non-woven fabric to filter out only dust, or may include a carbon filter that also functions as a pre-filter and deodorizing function.
공기 안내부(130)는, 외기가 먼지 필터(120)를 통해서 제품(90)으로 안내되도록 하기 위한 구성요소이다. 이러한 공기 안내부(130)는, 도 3에 도시된 바와 같이, 필터 케이스(110)에 구비될 수 있으며 외부 공기를 먼지 필터(120)와 제품(90)으로 순차적으로 안내할 수 있다. 공기 안내부(130)에 대한 보다 상세한 설명은 후술하기로 한다.The air guide unit 130 is a component that guides outside air to the product 90 through the dust filter 120. As shown in FIG. 3, this air guide unit 130 may be provided in the filter case 110 and may sequentially guide external air to the dust filter 120 and the product 90. A more detailed description of the air guide unit 130 will be described later.
따라서, 위와 같은 구성요소들이 제공되므로, 외기가 제품(90)에 마련된 공기 유입공(91)을 거쳐 제품의 내부로 유입되기에 앞서, 외기가 공기 안내부(130)를 따라 필터 케이스(110)의 내부에 마련된 먼지 필터(120)를 거친 후 제품(90)의 공기 유입공(91)으로 안내될 수 있어, 즉 외기에 포함된 먼지가 먼지 필터(120)를 통해 여과되어 제품(90)에 마련된 공기 유입공(91)으로는 안내될 수 있어, 제품 내부로의 먼지 유입의 최소화로 화재 발생을 방지할 수 있고, 냉각 효율을 높일 수 있으며, 제품의 수명 등을 개선할 수 있다.Therefore, since the above components are provided, before the outside air flows into the product through the air inlet hole 91 provided in the product 90, the outside air flows into the filter case 110 along the air guide portion 130. After passing through the dust filter 120 provided inside, it can be guided to the air inlet hole 91 of the product 90, that is, the dust contained in the outside air is filtered through the dust filter 120 and enters the product 90. It can be guided through the provided air inlet hole 91, preventing fires by minimizing the inflow of dust into the product, increasing cooling efficiency, and improving the lifespan of the product.
이하, 도 3과 도 6을 다시 참조하여, 공기 안내부(130)에 대해 보다 상세히 설명한다.Hereinafter, referring again to FIGS. 3 and 6, the air guide unit 130 will be described in more detail.
공기 안내부(130)는, 도 3에 도시된 바와 같이, 복수의 외기 유입 개구부(131), 내부 유로부(132), 그리고 여과 공기 유출 개구부(133)를 포함할 수 있다. 각각의 외기 유입 개구부(131)는 필터 케이스(110) 중 제품(90)의 외면이 향하는 방향과 동일한 방향으로 향하는 전면에 형성될 수 있으며 외기를 내부 유로부(132)로 안내할 수 있다. 내부 유로부(132)는 필터 케이스(110)의 내부를 이룰 수 있고 각각의 외기 유입 개구부(131)와 연통될 수 있으며 먼지 필터(120)를 수용할 수 있다. 여과 공기 유출 개구부(133)는 필터 케이스(110) 중 제품(90)의 외면을 향하는 배면에 형성될 수 있으며 내부 유로부(132)를 경유하면서 먼지 필터(120)에 의해 여과된 공기를 제품(90)으로 안내할 수 있다.As shown in FIG. 3 , the air guide unit 130 may include a plurality of external air inlet openings 131, an internal flow path 132, and a filtered air outlet opening 133. Each outside air inlet opening 131 may be formed on the front of the filter case 110 facing in the same direction as the outer surface of the product 90 and may guide outside air to the internal flow path portion 132. The internal flow path portion 132 may form the inside of the filter case 110, communicate with each outside air inlet opening 131, and accommodate the dust filter 120. The filtered air outlet opening 133 may be formed on the rear side of the filter case 110 facing the outer surface of the product 90, and may allow the air filtered by the dust filter 120 to pass through the internal flow path 132 to the product ( 90).
나아가, 각각의 외기 유입 개구부(131)는, 도 6에 도시된 바와 같이, 먼지 받이부(131a)와 외기 유입구(131b)를 포함할 수 있다. 먼지 받이부(131a)는 필터 케이스(110)의 전면이 프레스 가공되어 외측으로 볼록하게 눌리면서 돌출될 수 있으며 아래로 향하는 먼지를 받을 수 있다. 외기 유입구(131b)는 먼지 받이부(131a)의 하단이 필터 케이스(110)의 전면에서 절개되어 개구될 수 있다. 따라서, 자유 낙하하는 먼지가 외기 유입구(131b)에 쌓이지 않고 먼지 받이부(131a)에 우선적으로 쌓일 수 있어, 자유 낙하는 먼지로부터 외기 유입구(131b)가 막히는 등의 현상을 최소화할 수 있다.Furthermore, each outside air inlet opening 131 may include a dust receiver 131a and an outside air inlet 131b, as shown in FIG. 6 . The dust receiving portion 131a may be protruded by pressing the front of the filter case 110 to be convexly pressed outward and receive downward dust. The outside air inlet 131b may be opened by cutting the lower end of the dust receiver 131a from the front of the filter case 110. Accordingly, free-falling dust can preferentially accumulate in the dust receiving portion 131a rather than accumulating in the outside air inlet 131b, thereby minimizing phenomena such as clogging of the outside air inlet 131b from free-falling dust.
이와 더불어, 본 발명의 일 실시예에 따른 먼지 유입 방지 장치(100)는, 도 4 및 도 5에 도시된 바와 같이 필터 인입출부(140)를 더 포함할 수 있다. 필터 인입출부(140)는 필터 케이스(110) 중 제품(90)의 외면과 수직한 측면에 구비될 수 있으며 필터 케이스(110)의 내부로 먼지 필터(120)의 인입출을 안내할 수 있다. 따라서, 본 발명의 먼지 유입 방지 장치(100)가 벽면에 인접되도록 제품이 설치되더라도 필터 케이스(110)의 측면은 벽면과 제품(90) 사이의 공간에 항시 노출된 상태를 유지할 수 있어, 무거운 냉장고 등의 제품을 사용자가 직접 앞으로 빼지 않더라도 이러한 노출된 공간과 필터 인입출부(140)를 통해 먼지 필터(120)의 교환이 보다 수월하게 이루어질 수 있다.In addition, the dust inflow prevention device 100 according to an embodiment of the present invention may further include a filter inlet/outlet portion 140 as shown in FIGS. 4 and 5. The filter inlet/outlet portion 140 may be provided on a side of the filter case 110 perpendicular to the outer surface of the product 90 and may guide the inlet/outlet of the dust filter 120 into the filter case 110. Therefore, even if the product is installed so that the dust inflow prevention device 100 of the present invention is adjacent to the wall, the side of the filter case 110 can always remain exposed to the space between the wall and the product 90, allowing a heavy refrigerator. Even if the user does not directly pull out the product, the dust filter 120 can be replaced more easily through this exposed space and the filter retractable/output portion 140.
나아가, 필터 인입출부(140)는, 도 4 및 도 5에 도시된 바와 같이, 좌측 필터 인입출구(141)와 우측 필터 인입출구(142)를 포함할 수 있다. 좌측 필터 인입출구(141)는 필터 케이스(110)의 좌측면에 구비될 수 있고, 우측 필터 인입출구(142)는 필터 케이스(110)의 우측면에 구비될 수 있다. 따라서, 본 발명의 장치(100)의 전면부가 제1 벽면에 인접되고 본 발명의 장치(100)의 좌측면부가 제2 벽면에 인접되도록 제품이 설치되더라도 필터 케이스(110)의 우측면은 벽면과 제품(90) 사이의 공간에 항시 노출된 상태를 유지할 수 있어, 무거운 냉장고 등의 제품을 사용자가 직접 앞으로 빼지 않더라도 이러한 노출된 공간과 우측 필터 인입출구(142)를 통해 먼지 필터(120)의 교환이 보다 수월하게 이루어질 수 있다. 물론, 이와 반대로 본 발명의 장치(100)의 우측면부가 제2 벽면에 인접되도록 제품이 설치되더라도 좌측 필터 인입출구(141)를 통해 교환이 가능할 것이다.Furthermore, the filter inlet/outlet 140 may include a left filter inlet/outlet 141 and a right filter inlet/outlet 142, as shown in FIGS. 4 and 5 . The left filter inlet and outlet 141 may be provided on the left side of the filter case 110, and the right filter inlet and outlet 142 may be provided on the right side of the filter case 110. Therefore, even if the product is installed so that the front part of the device 100 of the present invention is adjacent to the first wall and the left side of the device 100 of the present invention is adjacent to the second wall, the right side of the filter case 110 is connected to the wall and the product. Since the space between (90) can be maintained at all times, the dust filter (120) can be replaced through this exposed space and the right filter inlet/outlet (142) even if the user does not directly pull out a heavy product such as a refrigerator. It can be done more easily. Of course, on the contrary, even if the product is installed so that the right side of the device 100 of the present invention is adjacent to the second wall, exchange will be possible through the left filter inlet and outlet 141.
이와 더불어, 본 발명의 일 실시예에 따른 먼지 유입 방지 장치(100)는, 도 3에 도시된 바와 같이 케이스 착탈부(150)를 더 포함할 수 있다. 케이스 착탈부(150)는 필터 케이스(110)를 제품(90)에 착탈시킬 수 있다. 따라서, 케이스 착탈부(150)를 통해, 기존의 냉장고 등의 제품에도 본 발명의 먼지 유입 방지 장치(100)를 설치할 수 있어, 기존의 냉장고 등의 제품을 통째로 바꾸지 않아도 본 발명의 장치(100)만을 구입해서 기존의 냉장고의 제품에 설치하는 것으로 화재 등을 방지할 수 있는 등 가성비를 극대화할 수 있다.In addition, the dust inflow prevention device 100 according to an embodiment of the present invention may further include a case removable part 150 as shown in FIG. 3. The case attachment/detachment unit 150 may attach or detach the filter case 110 to the product 90.
