Description

냉장고의 균일 냉각 구조Uniform cooling structure of the refrigerator

본 발명은 냉장고에 관한 것으로서, 특히 균일 냉각 성능을 향상시키는 동시에 소음을 저감하기 위한 냉각팬의 구조에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a structure of a cooling fan for reducing noise while improving uniform cooling performance.

종래 냉장고는 도 1 에 도시된 바와 같이, 전면은 냉동실(1)과 냉장실(2)로 구성되어 있고, 후면에는 냉매와 공기의 열교환 작용으로 냉기를 발생시키는 증발기(3)가 위치하며, 상기 증발기(3)로부터 발생된 냉기를 냉동실(1) 및 냉장실(2)로 토출하는 냉각팬(4)이 증발기(3)의 토출측에 위치한다.As shown in FIG. 1, a conventional refrigerator includes a freezing compartment 1 and a refrigerating compartment 2, and an evaporator 3 generating cold air by a heat exchange action between a refrigerant and air is located at a rear side of the refrigerator. A cooling fan 4 for discharging the cold air generated from (3) to the freezing chamber 1 and the refrigerating chamber 2 is located on the discharge side of the evaporator 3.

또한, 상기 냉각팬(4)으로부터 토출된 냉기가 모여 냉동실(1) 또는 냉장실(2)로 분배되는 슈라우드(5)가 냉동실(1)과 냉각팬(4)의 사이에 위치한다.In addition, a shroud 5, in which cold air discharged from the cooling fan 4 is collected and distributed to the freezing chamber 1 or the refrigerating chamber 2, is positioned between the freezing chamber 1 and the cooling fan 4.

그리고, 상기 슈라우드(5)에는 냉기의 냉동실(1)측 통로가 되는 그릴(6)이 접해 있으며, 냉기의 냉장실(2)측 유로를 구성하는 멀티 덕트(7)가 연결되어 있다.In addition, the shroud 5 is in contact with a grill 6 serving as a freezing chamber 1 side passage of cold air, and a multi duct 7 constituting a flow path of the cold storage chamber 2 side of cold air is connected.

이와 같이 구성된 종래의 냉장고는 증발기(3)로부터 냉매와 공기의 열교환 작용에 의해 냉기가 발생되며, 이 냉기는 냉각팬(4)을 통해 토출되고, 슈라우드(5)에서 냉동실(1)과 냉장실(2)로 분배된다.In the conventional refrigerator configured as described above, cold air is generated by the heat exchange action between the refrigerant and the air from the evaporator 3, and the cold air is discharged through the cooling fan 4, and the freezer compartment 1 and the refrigerating compartment ( 2) is distributed.

이때, 냉동실(1)측은 그릴(6)을 통해 냉기가 토출된 후 고내를 냉각시키게 되고, 다시 증발기(3)로 흡입되며, 냉장실(2)측은 슈라우드(5)로부터 멀티 덕트(7)로 냉기가 유입되고, 이 냉기는 냉장실(2) 전체에 고르게 분배되어 냉장실(2)의 온도를 낮추게 되는 것이다.At this time, the freezer compartment 1 side cools the inside of the refrigerator after the cold air is discharged through the grille 6, and is sucked into the evaporator 3 again, and the cold compartment 2 side is cold air from the shroud 5 to the multi duct 7. Is introduced, and this cold air is evenly distributed throughout the refrigerating chamber 2 to lower the temperature of the refrigerating chamber 2.

그러나 이러한 종래의 냉장고는 하나의 냉각팬을 사용하는 구조이므로 냉동실과 냉장실 고내에 유입되는 냉기의 유동형태가 비대칭이 되며, 특히 냉동실의 슈라우드 내부에서의 유동이 비대칭성이 강하여 재순환영역이 발생되므로 균일 냉각 성능이 저하되고, 소음이 발생되는 문제점이 있었다.However, since the conventional refrigerator has a structure using a single cooling fan, the flow of cold air introduced into the freezer compartment and the refrigerating compartment is asymmetrical, and in particular, since the flow inside the shroud of the freezer compartment is highly asymmetric, a recirculation area is generated. Cooling performance is reduced, there was a problem that the noise is generated.

본 발명은 이러한 점을 감안하여 냉각팬을 대칭되게 2개소 설치하고, 그 회전방향을 반대로 구동하여 냉동실 또는 냉장실내에서 냉기의 흐름을 대칭으로 형성함으로써 저소음 및 균일 냉각을 가능하게 하는 데 그 목적이 있다.In view of this point, the present invention provides two cooling fans symmetrically and drives the rotational direction oppositely to form symmetrical flows of cold air in the freezer compartment or the refrigerating compartment to enable low noise and uniform cooling. have.

이하, 본 발명의 실시예를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2 는 본 발명에 의한 냉장고의 구성도로서, 전면은 냉동실(101)과 냉장실(102)로 구성되어 있고, 상기 냉동실(101)의 후면에는 냉매와 공기의 열교환 작용으로 냉기를 발생시키는 증발기(103)가 위치하며, 상기 증발기(103)로부터 발생된 냉기를 냉동실(101) 및 냉장실(102)로 토출하는 냉각팬(104)(104')이 냉장고 중앙을 기준으로 좌, 우 대칭으로 증발기(103)의 토출측에 2개소 배치되어 있다.2 is a configuration diagram of a refrigerator according to the present invention, the front surface of which consists of a freezing compartment 101 and a refrigerating compartment 102, and an evaporator for generating cold air by a heat exchange action between a refrigerant and air on the rear surface of the freezing compartment 101 ( 103 is positioned, and cooling fans 104 and 104 'for discharging the cold air generated from the evaporator 103 to the freezer compartment 101 and the refrigerating compartment 102 are left and right symmetrical with respect to the center of the refrigerator. It is arrange | positioned at two places on the discharge side of 103.

또한, 상기 냉각팬(104)(104')으로부터 토출된 냉기가 모여 냉동실(101) 또는 냉장실(102)로 분배되는 슈라우드(105)가 냉동실(101)과 냉각팬(104)(104')의 사이에 위치하고, 냉기의 냉동실(101)측 통로가 되는 그릴(106)과, 냉기를 냉장실 전체에 고르게 분배하기 위한 멀티 덕트(107)(107')가 상기 슈라우드(105)에 연결되어 있다.In addition, the shroud 105, in which cold air discharged from the cooling fans 104 and 104 'is collected and distributed to the freezing chamber 101 or the refrigerating chamber 102, is formed of the freezing chamber 101 and the cooling fans 104 and 104'. The grill 106, which is located between the two sides and serves as a passage for the freezer compartment 101 side of the cold air, and the multiple ducts 107 and 107 'for evenly distributing the cold air to the entire refrigerator compartment, are connected to the shroud 105.

그리고, 상기 멀티 덕트(107)(107')는 냉기의 유동형태가 냉장실(102) 내에서 대칭이 되도록 냉장실(102) 후면 코너부위에 2개소 배치되어 있다.The two ducts 107 and 107 ′ are disposed at two rear corners of the refrigerating chamber 102 so that the flow of cold air is symmetric in the refrigerating chamber 102.

이하에서는 본 발명에 의한 작용을 설명한다.Hereinafter, the operation by the present invention will be described.

먼저, 증발기(103)로부터 발생된 냉기는 2개의 냉각팬(104)(104')을 통해 슈라우드(105)로 토출되며, 냉동실 토출그릴로 냉기를 토출한 후 일부 냉기가 슈라우드(105) 양쪽 냉장실(102) 흡입 유로를 통해 멀티 덕트(107)(107')로 유입되어 냉장실(102)을 냉각하게 된다.First, the cold air generated from the evaporator 103 is discharged to the shroud 105 through two cooling fans 104 and 104 ', and after the cold air is discharged to the freezer discharge grill, some cold air is discharged from both sides of the shroud 105. 102 is introduced into the multi ducts 107 and 107 ′ through the suction channel to cool the refrigerating compartment 102.

이때, 상기 냉각팬(104)(104') 중 하나는 정방향의 회전을, 다른 하나는 역방향의 회전을 하게 되므로 냉기의 유동이 대칭형태가 된다.In this case, one of the cooling fans 104, 104 'is rotated in the forward direction, the other is rotated in the reverse direction, so the flow of cold air becomes symmetrical.

상기에 설명한 바와 같이, 슈라우드(105) 내부에서 대칭형태로 유동하는 냉기는 대칭으로 형성되어 있는 2개의 멀티 덕트(107)(107')를 통해 냉장실(102) 내에서도 대칭형태로 유동하게 되어 냉장실(102) 전체의 균일 냉각이 가능해 지는 것이다.As described above, the cold air flowing in the symmetrical form in the shroud 105 flows symmetrically in the refrigerating compartment 102 through the two ducts 107 and 107 'which are formed symmetrically. 102) Uniform cooling of the whole is possible.

한편, 슈라우드(105)로 토출된 일부 냉기는 냉동실(101)의 그릴(106)을 통해 냉동실(101)로 토출되며, 냉동실(101) 내부에서도 냉기의 유동이 대칭형태를 갖는다.On the other hand, some of the cold air discharged to the shroud 105 is discharged to the freezing chamber 101 through the grill 106 of the freezing chamber 101, the flow of cold air in the freezing chamber 101 has a symmetrical form.

이에 따라, 냉장실(102)과 마찬가지로 냉동실(101)에서도 균일 냉각이 가능해 진다.As a result, the cooling chamber 101 can be uniformly cooled similarly to the refrigerating chamber 102.

상기 냉동실(101)을 균일 냉각시킨 냉기는 다시 증발기(103)로 유입되며, 이러한 과정은 시스템이 수평을 이룬 상태에서 전원이 인가되어 있는 동안 반복된다.The cold air having uniformly cooled the freezer compartment 101 flows back into the evaporator 103, and this process is repeated while power is applied while the system is in a horizontal state.

이상에서 설명한 바와 같이 본 발명은 냉기의 유동이 대칭형태를 갖게 되어 냉장실 및 냉동실에서의 균일 냉각이 가능해 지고, 재순환 영역이 발생되지 않으므로 소음이 저감되는 효과가 있다.As described above, the present invention has an effect that the flow of cold air has a symmetrical form, thereby enabling uniform cooling in the refrigerating compartment and the freezing compartment, and reducing noise since no recirculation zone is generated.
