Description

냉장고 고내용 송풍기 및 이를 포함하는 냉장고{AIR BLOWER FOR REFRIGERATOR AND REFRIGERATOR COMPRISING THE SAME}TECHNICAL FIELD [0001] The present invention relates to a refrigerator high-content blower and a refrigerator including the same. BACKGROUND OF THE INVENTION [0002]

본 발명은 냉장고 고내용 송풍기 및 이를 포함하는 냉장고에 대한 발명이다. The present invention relates to a refrigerator high-content blower and a refrigerator including the same.

냉장고는 식품을 저온에 보관하여 부패, 변질을 방지하는 장치로서, 고내에서 식품을 냉장보관 또는 냉동보관할 수 있다. 냉장고의 고내는 일반적으로 냉장실과 냉동실로 구획될 수 있고, 냉장고는 고내에 냉기를 공급하는 열교환기를 포함한다. A refrigerator is a device for preventing food from being decayed and deteriorated by storing food at a low temperature, and the food can be stored in a refrigerator or in a refrigerator at a high temperature. The hearth of the refrigerator can be generally divided into a refrigerator compartment and a freezer compartment, and the refrigerator includes a heat exchanger that supplies cold air to the compartment.

냉장고의 내부에 공급되는 냉기는 열교환기에서의 냉매 열교환 작용에 의해서 생성된다. 다시 말해, 냉기는 열교환기에서의 압축-응축-팽창-증발의 사이클(Cycle)의 반복에 의해 생성되고, 냉장고의 내부로 공급된다. 공급된 냉기는 대류에 의해서 냉장고 내부에 고르게 전달되어 냉장고 내부의 음식물을 원하는 온도로 저장할 수 있게 된다.The cool air supplied to the inside of the refrigerator is generated by the refrigerant heat exchange action in the heat exchanger. In other words, the cold air is generated by repetition of the cycle of compression-condensation-expansion-evaporation in the heat exchanger, and is supplied to the inside of the refrigerator. The supplied cold air is uniformly transferred to the inside of the refrigerator by the convection so that the food inside the refrigerator can be stored at a desired temperature.

이러한 사이클은 냉장고에 식품을 저장하는 냉장실, 냉동실과 같은 저장공간과 별개로 냉장고의 일측에 설치된다. 예를 들어, 압축, 응축과정은 냉장고의 배면 하측에 형성되는 기계실에 배치되는 압축기와 응축기에 의해 이루어질 수 있다. 또한, 증발과정에서는 냉매의 증발에 의해, 냉매가 주변공기의 열을 흡수하고, 주변 공기를 냉각시킬 수 있다. Such a cycle is installed on one side of the refrigerator separately from the storage space such as a refrigerator compartment and a freezer compartment for storing food in the refrigerator. For example, the compression and condensation processes can be performed by a compressor and a condenser disposed in a machine room formed under the rear of the refrigerator. Also, in the evaporation process, the evaporation of the refrigerant allows the refrigerant to absorb the heat of the surrounding air and cool the surrounding air.

이러한 열교환기의 증발에서 냉각된 공기는 고내로 보내질 필요가 있다. 따라서, 냉장고는 냉기를 고내로 보낼 수 있는 팬과 이를 구동시키기 위한 모터(냉장고 고내용 송풍기)가 구비된다. In the evaporation of these heat exchangers, the cooled air needs to be sent into the furnace. Accordingly, the refrigerator is provided with a fan capable of sending cool air into the high temperature and a motor (refrigerator high-content blower) for driving the fan.

그러나, 냉장고 고내용 송풍기에서의 팬과 모터의 회전에 따라, 지나치게 큰 진동과 소음이 발생한다는 문제가 있다. However, there is a problem that excessive vibration and noise are generated due to the rotation of the fan and the motor in the refrigerator high-content blower.

이하, 도 1 내지 도 5를 참조하여 본 발명의 일 실시예에 따른 냉장고 고내용 송풍기의 구체적인 구성에 대하여 설명한다. 도 1은 본 발명의 일 실시예에 따른 냉장고 고내용 송풍기가 냉장고에 구비된 것을 나타낸 사시도이고, 도 2는 도 1의 냉장고의 측면도이고, 도 3은 도 1의 냉장고 고내용 송풍기의 사시도이며, 도 4는 도 3의 냉장고 고내용 송풍기의 분해 사시도이고, 도 5는 도 3의 냉장고 고내용 송풍기의 정면도이다. Hereinafter, a detailed configuration of a refrigerator high-content blower according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 is a perspective view of a refrigerator according to an embodiment of the present invention. FIG. 2 is a side view of the refrigerator of FIG. 1, FIG. 3 is a perspective view of the refrigerator high- FIG. 4 is an exploded perspective view of the refrigerator high-content blower of FIG. 3, and FIG. 5 is a front view of the refrigerator high-content blower of FIG.

도 1 내지 도 5를 참조하면, 본 발명의 일 실시예에 따른 냉장고(1)는 냉장고 고내(room, 10) 및 고내용 송풍기(20)를 포함할 수 있다. 1 to 5, a refrigerator 1 according to an embodiment of the present invention may include a refrigerator room 10 and a high-content blower 20. As shown in FIG.

또한, 냉장고(1)는 냉장고 고내(10)에 냉기를 공급하기 위해, 증발기(30), 압축기(40), 및 응축기(50)를 구비하는 냉각부를 포함할 수 있다. 또한,이러한 냉각부는 일 예로, 증발기(30), 압축기(40) 및 응축기(50)를 포함할 수 있다. 고내용 송풍기(20)는 증발기(30)에서 냉각된 공기를 냉장고 고내(10)에 공급하도록 구성될 수 있다. The refrigerator 1 may also include a cooling unit including an evaporator 30, a compressor 40 and a condenser 50 for supplying cold air to the inside of the refrigerator 10. [ In addition, the cooling section may include, for example, an evaporator 30, a compressor 40, and a condenser 50. [ The high-content blower 20 may be configured to supply the cooled air from the evaporator 30 to the refrigerator compartment 10. [

이하, 냉각부에 의해 공기가 냉각되는 과정을 설명한다. 증발기(30)를 통해 주변공기와 열교환된 고온의 냉매가스가 압축기(40)로 보내져 압축되고, 압축기(40)를 통해 압축된 냉매는 응축기(50)를 거치면서 응축열을 외부로 방열시키면서 액화된다. 이러한 응축기(50)를 거친 액화냉매는 증발기(30)로 보내진다. 증발기(30)로 보내진 액화냉매는 주변공기와의 열교환에 의해 기화되면서 주변의 열을 흡수한다. 증발기(30)의 액화냉매는 주변공기로부터 열을 전달받고, 증발기(30)의 액화냉매의 전부 또는 일부가 기체 상태의 냉매로 바뀐다. 이후, 기체상태의 냉매가 액체상태의 냉매로부터 분리되어 다시 압축기(40)로 유입된다. 증발기(30)에서는 냉매가 증발기(30) 외부 공기의 열을 흡수한다. 이러한 열전달을 통해 증발기(30)는 냉장고의 공기를 냉각시킨다. 증발기(30)에서 냉각된 공기는 냉장고 고내(10)로 전달되어 냉장고 고내(10)를 냉각시킨다. Hereinafter, the process of cooling the air by the cooling unit will be described. The high-temperature refrigerant gas that has been heat-exchanged with the ambient air through the evaporator 30 is sent to the compressor 40 and is compressed. The refrigerant compressed through the compressor 40 is condensed while passing through the condenser 50, . The liquefied refrigerant passing through the condenser (50) is sent to the evaporator (30). The liquefied refrigerant sent to the evaporator 30 is vaporized by heat exchange with ambient air and absorbs the surrounding heat. The liquefied refrigerant of the evaporator 30 receives heat from the surrounding air, and all or a part of the liquefied refrigerant of the evaporator 30 is converted into the gaseous refrigerant. Thereafter, the gaseous refrigerant is separated from the refrigerant in the liquid state and flows into the compressor 40 again. In the evaporator (30), the refrigerant absorbs the heat of the air outside the evaporator (30). Through this heat transfer, the evaporator 30 cools the air of the refrigerator. The air cooled by the evaporator (30) is transferred to the inside of the refrigerator (10) to cool the inside of the refrigerator (10).

냉장고 고내용 송풍기(20)는 증발기(30)에서 냉각된 공기(냉기)를 고내(10)로 공급하도록 구비될 수 있다. 예를 들어, 냉장고 고내용 송풍기(20)의 구동장치(100)는 증발기(30) 주변의 냉기가 고내(10)로 흐르는 방향으로 회전할 수 있다. 또한, 냉장고 고내용 송풍기(20)의 팬(300)은 증발기(30) 주변의 냉기가 고내(10)로 흐르는 방향으로 설치될 수 있다. 이러한 냉장고 고내용 송풍기(20)는 증발기(30)에 인접하여 구비될 수 있다. The refrigerator high-content blower 20 may be provided to supply air (cool air) cooled in the evaporator 30 to the inside of the high-temperature chamber 10. For example, the driving device 100 of the refrigerator high-content blower 20 can rotate in a direction in which the cool air around the evaporator 30 flows into the high-temperature chamber 10. In addition, the fan 300 of the refrigerator high-content blower 20 can be installed in such a direction that the cool air around the evaporator 30 flows into the high-temperature inside 10. The refrigerator high-content blower 20 may be provided adjacent to the evaporator 30.

이러한 냉장고 고내용 송풍기(20)는 구동장치(100), 바디(200), 팬(300) 및 하우징(400)을 포함한다. The refrigerator high-content blower 20 includes a driving device 100, a body 200, a fan 300, and a housing 400.

구동장치(100)는 팬을 회전시키기 위한 동력을 발생시킨다. 구동장치(100)는 하우징(400)에 의해 지지되고, 구동장치의 회전축(110)은 하우징(400)의 반대측으로 연장되어 바디(200)와 연결될 수 있다. 이러한 구동장치(100)는 구동장치 수용부(210) 내에 구비된 상태에서 하우징(400)에 지지될 수 있다. 한편, 구동장치는 일예로, 회전축을 포함하는 전기모터일 수 있으나, 반드시 이에 한정되는 것은 아니다. 또한, 구동장치(100)는 그 회전축(110)이 회전하고 회전축(110)이 바디와 연결되도록 구성될 수 있고, 로터가 회전하고, 로터가 바디와 연결되도록 구성될 수 있다. The driving apparatus 100 generates power for rotating the fan. The driving device 100 is supported by the housing 400 and the rotating shaft 110 of the driving device may extend to the opposite side of the housing 400 and may be connected to the body 200. The driving apparatus 100 may be supported by the housing 400 in a state where the driving apparatus 100 is installed in the driving apparatus accommodating unit 210. On the other hand, the driving device may be, for example, an electric motor including a rotating shaft, but is not limited thereto. In addition, the driving apparatus 100 may be configured such that the rotary shaft 110 is rotated and the rotary shaft 110 is connected to the body, and the rotor is rotated and the rotor is connected to the body.

바디(200)는 구동장치 수용부(210)와 지지부(220)를 포함할 수 있다. 구동장치 수용부(210) 내에는 구동장치(100)가 배치될 수 있다. 또한, 구동장치 수용부(210)는, 구동장치(100)의 회전에 의해 회전될 수 있도록 구동장치(100)와 연결될 수 있다. 한편, 구동장치(100)와 수동장치 수용부(210)가 연결되는 방식에는 제한이 없다. 예를 들어, 구동장치(100)의 축이 구동장치 수용부(210)가 연결될 수 있고, 다른 예로, 구동장치(100)의 로터가 구동장치 수용부(210)와 연결될 수 있다. 이러한 구동장치 수용부(210)는 축방향에서 보았을 때 원형의 형상을 가질 수 있다. 또한, 구동장치 수용부(210)는 회전축 방향으로 인입된 리스세로 구성될 수 있고, 이러한 리세스는 구동장치(100)를 수용할 수 있다. 따라서, 구동장치 수용부(210)는 구동장치(100)를 커버할 수 있다. 다시 말해, 구동장치(100)는 일측이 하우징(400)에 의해 커버되고, 나머지가 구동장치 수용부(210)에 의해 커버될 수 있다. The body 200 may include a driving device receiving portion 210 and a supporting portion 220. The driving apparatus 100 may be disposed in the driving apparatus accommodating unit 210. The driving device accommodating portion 210 may be connected to the driving device 100 so that the driving device accommodating portion 210 can be rotated by the rotation of the driving device 100. There is no limitation on the manner in which the drive device 100 and the passive device accommodating portion 210 are connected. For example, the shaft of the driving apparatus 100 may be connected to the driving apparatus accommodating portion 210, and in another example, the rotor of the driving apparatus 100 may be connected to the driving apparatus accommodating portion 210. The driving device accommodating portion 210 may have a circular shape when viewed in the axial direction. Further, the drive device accommodating portion 210 can be configured as a recessed portion that is drawn in the direction of the rotational axis, and such recess can accommodate the drive device 100. [ Therefore, the drive device accommodating portion 210 can cover the drive device 100. [ In other words, one side of the driving apparatus 100 may be covered by the housing 400, and the remaining one may be covered by the driving apparatus accommodating portion 210.

또한, 구동장치 수용부(210)는 지지부(220)와 일체로 형성될 수 있다. 이 경우, 구동장치 수용부(210)는 지지부(220)로부터 축방향 일측으로 돌출되도록 형성될 수 있다. 여기서, '축방향'은 구동장치(100)의 회전축이 연장되는 방향(Z 방향)을 의미하고, '축방향 일측'은 회전축이 구동장치(100)로부터 구동장치 수용부(210)를 향하여 연장되는 방향(+Z 방향)을 의미한다. Also, the driving device accommodating portion 210 may be formed integrally with the supporting portion 220. In this case, the driving device accommodating portion 210 may be formed to protrude from one side of the supporting portion 220 in the axial direction. Here, the 'axial direction' means a direction in which the rotation axis of the driving apparatus 100 extends (Z direction), and the 'axial direction side' means that the rotation axis extends from the driving apparatus 100 to the driving apparatus receiving portion 210 Direction (+ Z direction).

본 실시예에 따른 도면에서는, 구동장치 수용부(210)가 지지부(220)와 일체로 형성되는 것으로 나타내었으나, 반드시 이에 한정되는 것은 아니다. 예를 들어, 구동장치 수용부(210)가 지지부(220)와 별도의 부재로 형성되는 것도 가능하다. In the drawings according to the present embodiment, the drive unit accommodating portion 210 is shown as being formed integrally with the support portion 220, but the present invention is not limited thereto. For example, the driving device accommodating portion 210 may be formed as a separate member from the supporting portion 220.

지지부(220)는 팬(300)을 지지한다. 팬(300)은 지지부(220)가 연장되는 방향과 어긋나는 방향으로 연장될 수 있다. 예를 들어, 지지부(220)가 회전축의 반경방향(r 방향)을 향해 연장되고, 팬(300)은 축방향 일측을 향해 연장될 수 있다. 이러한 지지부(220)는 구동장치(100)에 의해 회전될 수 있다. 또한, 지지부(220)는 원형의 판 부재를 포함할 수 있다. 또한, 지지부(220)는 구동장치 수용부(210)와 동일한 중심을 가질 수 있다. 다시 말해, 지지부(220)는 구동장치 수용부(210)와 동일한 중심축으로 회전하게 된다. The support portion 220 supports the fan 300. The fan 300 may extend in a direction that is deviated from the direction in which the support portion 220 extends. For example, the support portion 220 may extend toward the radial direction (r direction) of the rotation shaft, and the fan 300 may extend toward one axial side. The supporting portion 220 can be rotated by the driving device 100. [ Further, the support portion 220 may include a circular plate member. In addition, the support portion 220 may have the same center as the drive device receiving portion 210. In other words, the support portion 220 rotates about the same center axis as the drive device accommodating portion 210.

또한, 회전축 방향에서 보았을 때, 구동장치 수용부(210)의 폭(D1)은 지지부(220)의 폭(D2)의 대략 0.55±0.1배일 수 있다. 다시 말해, 지지부(220)의 폭(D2)에 대한 구동장치 수용부(210)의 폭(D1)의 비율은 대략 0.45이상, 0.65이하일 수 있다. 지지부(220)의 폭(D2)에 대한 구동장치 수용부(210)의 폭(D1)의 비율이 대략 0.45보다 작으면, 지나치게 큰 소음이 발생하고, 지지부(220)의 폭(D2)에 대한 구동장치 수용부(210)의 폭(D1)의 비율보다 크면, 고내용 송풍기(20)의 풍량이 불충분하여 냉각이 효과적으로 이루어지기 어렵다. 한편, 도면에 나타난 것과 같이 구동장치 수용부(210)와 지지부(220)가 원형으로 형성되는 경우, 구동장치 수용부의 폭(D1)은 구동장치 수용부의 직경일 수 있고, 지지부의 폭(D2)은 지지부의 직경일 수 있다.The width D1 of the drive unit accommodating portion 210 can be about 0.55 +/- 0.1 times the width D2 of the support portion 220 when viewed in the direction of the rotation axis. In other words, the ratio of the width D1 of the drive unit accommodating portion 210 to the width D2 of the support portion 220 can be approximately 0.45 or more and 0.65 or less. If the ratio of the width D1 of the drive unit accommodating portion 210 to the width D2 of the support portion 220 is less than about 0.45, an excessively large noise is generated and the ratio of the width D2 of the support portion 220 Is larger than the ratio of the width D1 of the drive device accommodating portion 210, the air volume of the high-content blower 20 is insufficient, and cooling is difficult to be effectively performed. The width D1 of the drive device accommodating portion may be the diameter of the drive device accommodating portion and the width D2 of the support portion may be the same as the width of the drive device accommodating portion 210. [ May be the diameter of the support.

팬(300)은 지지부(220)에 연결될 수 있다. 또한, 팬(300)은 지지부(220)와 어긋나는 방향으로 배치될 수 있다. 예를 들어, 팬(300)이 연장되는 방향은 회전축의 방향일 수 있다. 또한, 팬(300)이 연장되는 방향은 지지부(220)가 연장되는 방향과 대략 수직일 수 있다. 이러한 팬(300)은 축방향에서 보았을 때, 곡선 형상을 가진다. The fan 300 may be connected to the support 220. Further, the fan 300 may be disposed in a direction deviating from the support portion 220. For example, the direction in which the fan 300 extends may be the direction of the rotational axis. In addition, the direction in which the fan 300 extends may be substantially perpendicular to the direction in which the support portion 220 extends. The fan 300 has a curved shape when viewed in the axial direction.

이러한 팬(300)의 곡선 형상은 팬(300)의 입구각(β1)이 팬(300)의 출구각(β2)보다 크도록 형성될 수 있다. 여기서, '입구각(β1)'은 팬(300)의 반경 바깥쪽 단부로부터 바깥쪽으로 연장되는 연장선과 반경 바깥쪽 단부에서의 접선 사이의 각도를 의미한다. 여기서, '출구각(β2)' 팬(300)의 반경 안쪽 단부로부터 바깥쪽으로 연장되는 연장선과 반경 안쪽 단부에서의 접선 사이의 각도를 의미한다. 이러한 입구각(β1)은 대략 44°±5°일 수 있다. 다시 말해, 입구각(β1)은 대략 39°이상 49°이하일 수 있다. 또한, 출구각(β2)은 32°±2.5°일 수 있다. 다시 말해, 출구각(β2)은 대략 29.5°이상 34.5°이하일 수 있다. 입구각(β1) 또는 출구각(β2)이 상기의 범위를 벗어나는 경우, 지나치게 큰 소음이 발생하거나 고내용 송풍기(20)의 풍량이 불충분하여 냉각이 효과적으로 이루어지기 어렵다. The curved shape of the fan 300 may be formed such that the inlet angle? 1 of the fan 300 is larger than the outlet angle? 2 of the fan 300. [ Here, 'inlet angle (β 1 )' means an angle between an extension line extending outwardly from the radially outer end of the fan 300 and a tangent line at the radially outer end. Here, 'exit angle (? 2 )' means an angle between an extension line extending outwardly from an inner radius end of the fan 300 and a tangent line at an inner radius end. This inlet angle (beta 1 ) may be approximately 44 [deg.] + - 5 [deg.]. In other words, the entrance angle? 1 can be approximately 39 ° or more and 49 ° or less. Further, the exit angle (? 2 ) may be 32 ° ± 2.5 °. In other words, the exit angle? 2 can be approximately 29.5 ° to 34.5 °. When the inlet angle? 1 or the outlet angle? 2 is out of the above range, too much noise is generated or the air volume of the high-content blower 20 is insufficient, so that cooling is difficult to be effectively performed.

이러한 팬(300)은 7개 이상 9개 이하로 구비될 수 있다. 팬(300)의 개수가 7개 보다 적으면, 풍량이 불충분하게 되어 냉각이 효과적으로 이루어지기 어렵고, 팬(300)의 개수가 9개 보다 많으면 지나치게 큰 소음이 발생하게 된다. The number of the fans 300 may be seven or more and nine or less. If the number of the fans 300 is less than 7, the amount of air becomes insufficient and cooling is not effectively performed. If the number of the fans 300 is more than 9, too much noise is generated.

또한, 팬(300)은 축방향 일측에서 보조부재(310)와 연결되고, 축방향 타측에서 바디(200) 가 연결될 수 있다. 다시 말해, 팬(300)은 바디(200)와 보조부재(310)의 사이에 배치될 수 있다. 이러한 보조부재(310)는 링 형상을 가질 수 있다. 또한, 보조부재(310)는 반경 바깥쪽에서 복수 개의 팬(300)과 연결될 수 있다. The fan 300 may be connected to the auxiliary member 310 on one side in the axial direction and may be connected to the body 200 on the other side in the axial direction. In other words, the fan 300 may be disposed between the body 200 and the auxiliary member 310. The auxiliary member 310 may have a ring shape. In addition, the auxiliary member 310 may be connected to the plurality of fans 300 at a radius outside.

하우징(400)은 바디(200)와 팬(300)을 커버한다. 또한, 구동장치(100)를 지지할 수 있다. 이러한 하우징(400)은 바디(200)를 커버하도록 구성될 수 있다. 예를 들어, 바디(200)의 일 측에는 팬(300)이 배치되고, 바디(200)의 타측에는 하우징(400)이 배치될 수 있다. 다시 말해, 하우징(400)은 팬(300)의 반대편에 구비될 수 있다. The housing 400 covers the body 200 and the fan 300. Further, the driving apparatus 100 can be supported. The housing 400 may be configured to cover the body 200. For example, a fan 300 may be disposed on one side of the body 200, and a housing 400 may be disposed on the other side of the body 200. In other words, the housing 400 may be provided on the opposite side of the fan 300.

이하에서는, 냉장고 고내용 송풍기(20)의 작용 및 효과에 대하여 설명한다. 냉장고(1)의 제어부에서 고내(10)에 냉기의 공급이 필요하다고 판단된 경우, 냉장고 고내용 송풍기(20)가 가동된다. 냉장고 고내용 송풍기(20)는 증발기(30) 주변의 냉기를 고내(10)로 공급한다. 구동장치(100)의 회전력에 의해 바디(200)가 회전한다. 팬(300)은 바디(200)와 연결되어 있으므로, 바디(200)의 회전에 의해 팬(300)이 회전한다. 이러한 냉장고 고내용 송풍기(20)의 회전에 의해 증발기(30)의 냉기가 고내(10)로 효과적으로 공급될 수 있다. Hereinafter, the operation and effects of the refrigerator high-content blower 20 will be described. When it is judged by the control unit of the refrigerator 1 that it is necessary to supply cold air to the interior 10, the refrigerator high-content blower 20 is operated. The refrigerator high-content blower 20 supplies cold air around the evaporator 30 to the high-temperature inside 10. The body 200 is rotated by the rotational force of the driving apparatus 100. [ Since the fan 300 is connected to the body 200, the fan 300 is rotated by the rotation of the body 200. By the rotation of the refrigerator high-content blower 20, the cool air of the evaporator 30 can be effectively supplied to the inside space 10.
