Abstract

본 고안은 냉장고에 관한 것으로, 그 목적은 냉장실의 냉기공급장치를 개선하여 냉장실 전체를 균일하게 냉각시키는 것이다.The present invention relates to a refrigerator, and its object is to improve the cold air supply of the refrigerating compartment to uniformly cool the entire refrigerating compartment.
본 고안에 따른 냉장고는 냉장실(120) 후벽 중심부에 마련된 증발기(310)를 중심으로 대칭되게 공기흡입구(342)가 형성되어 냉장실 공기를 증발기(310) 하부로 안내하는 흡입덕트(340)를 구성하고, 냉기토출구(333)가 다단으로 형성되어 증발기(310)에서 생성된 냉기를 냉장실(120)로 안내하는 토출덕트(330) 역시 증발기(310) 양측단부에 대칭되게 마련되어 있다. 이 때, 토출덕트(330)의 하단부(332)는 흡입덕트(340)를 지나 냉장실(120) 후벽면 하부까지 연장되어 있다.The refrigerator according to the present invention has an air inlet 342 symmetrically formed around the evaporator 310 provided in the center of the rear wall of the refrigerating chamber 120 to form a suction duct 340 for guiding the refrigerating chamber air to the lower part of the evaporator 310. In addition, the cold air discharge port 333 is formed in multiple stages and the discharge duct 330 for guiding the cold air generated in the evaporator 310 to the refrigerating chamber 120 is also provided symmetrically at both ends of the evaporator 310. At this time, the lower end portion 332 of the discharge duct 330 extends through the suction duct 340 to the lower portion of the rear wall surface of the refrigerating chamber 120.
따라서 냉기배분이 별도 수단없이도 냉장실(120) 상부에서 하부까지 균일하게 이루어져 위치에 따른 온도편차가 발생되지 않고, 냉장실(120)에서 완전하게 열교환된 공기가 공기흡입구(343)를 통해 증발기(310)로 유입되기 때문에 냉동사이클의 열교환효율이 향상되는 이점이 있다.Therefore, even if the air distribution is uniformly made from the upper side to the lower side of the refrigerating chamber 120 without a separate means, the temperature difference according to the position does not occur, and the air completely heat-exchanged in the refrigerating chamber 120 passes through the air inlet 343 to the evaporator 310. Since it is introduced into the heat exchange efficiency of the refrigeration cycle is improved.

Description

냉장고Refrigerator
본 고안은 냉장고에 관한 것으로, 더욱 상세하게는 냉장실 공기를 흡입하여 냉기로 변환시키고 이를 다시 냉장실로 공급하는 냉장실 냉기공급장치에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a refrigerator compartment cold air supply device that sucks the refrigerator compartment air into a cold compartment and supplies it to the refrigerator compartment again.
냉장고는 일반적으로 냉동사이클의 증발기로부터 생성된 냉기를 냉동실과 냉장실로 공급하여 각종식품의 신선도를 장기간 유지할 수 있도록 구성되어 있는데, 도 1에 도시한 바와 같이, 외형 몸체를 이루는 캐비닛(1) 내부에 앞면이 개방된 저장실로서 냉동식품을 보관하는 냉동실(2)과 냉장식품을 보관하는 냉장실(3)이 중간격벽(9)에 의해 구획되게 형성되어 있으며, 냉동실(2)과 냉장실(3)을 개폐하는 도어(4,5)가 캐비닛(1) 앞면부에 힌지결합되어 있다.The refrigerator is generally configured to supply the cold air generated from the evaporator of the refrigeration cycle to the freezer compartment and the refrigerating compartment to maintain the freshness of various foods for a long time, as shown in FIG. 1, in the cabinet 1 forming the outer body. A freezer compartment (2) for storing frozen foods and a refrigerating compartment (3) for storing refrigerated foods are partitioned by an intermediate partition (9). The freezer compartment (2) and the refrigerating compartment (3) are opened and closed. The doors 4 and 5 are hingedly coupled to the front surface of the cabinet 1.
냉동실(2)의 후방에는 냉기를 생성하여 냉동실(2)과 냉장실(3)로 공급하는 별도의 냉각실(6)이 형성되어 있다. 여기에는 증발기(6a), 냉동실(2)과 냉장실(3)의 공기를 증발기(6a)로 유입시키고 생성된 냉기를 강제송풍시키는 순환팬(6b) 등이 내장된다. 그리고 이러한 냉기를 냉동실(2)과 냉장실(3)로 적절하게 분배 안내하도록 냉기유출공(7a,8a)이 배열형성된 냉동실덕트(7)와 냉장실덕트(8)가 후측에 세워져 설치되어 있고, 중간격벽(9) 내부에는 순환팬(6b)에 의해 흡입되는 냉동실(2)과 냉장실(3)의 공기를 증발기(6a)로 안내하는 복귀덕트(9a,9b)가 형성된다.In the rear of the freezing chamber 2, a separate cooling chamber 6 is formed to generate cold air and to supply the freezing chamber 2 and the refrigerating chamber 3. It includes a circulation fan 6b for introducing air from the evaporator 6a, the freezing chamber 2 and the refrigerating chamber 3 into the evaporator 6a and forcibly blowing the generated cold air. And freezing chamber duct 7 and refrigerating chamber duct 8 in which cold air outlet holes 7a and 8a are arranged to guide the cold air to the freezing chamber 2 and the refrigerating chamber 3 are set up on the rear side, Inside the partition 9, return ducts 9a and 9b are formed, which guide the air from the freezing chamber 2 and the refrigerating chamber 3, which are sucked by the circulation fan 6b, to the evaporator 6a.
그리고 냉동실(2)과 냉장실(3)에는 각각 식품을 수납하여 보관할 수 있도록 선반(2a,3a)이 가로방향으로 설치되어 있다. 냉장실(3)에는 내부공간이 냉동실(1)에 비해 크기 때문에 선반(3a)이 다단으로 마련되며, 하부에 수분을 함유하고 있는 야채류 등이 보관되는 별도의 야채박스(3b)가 구성된다.In the freezing chamber 2 and the refrigerating chamber 3, shelves 2a and 3a are provided in the horizontal direction so as to accommodate and store food, respectively. Since the internal space is larger than the freezer compartment 1 in the refrigerating compartment 3, the shelf 3a is provided in multiple stages, and a separate vegetable box 3b for storing vegetables and the like containing moisture therein is provided.
이와 같이 구성된 냉장고에서 순환팬(6b)이 작동하면, 냉동실(2)과 냉장실(3)의 공기는 복귀덕트(9a,9b)를 통해 증발기(6a) 하부로 유입되고, 이것은 증발기(6a)를 지나면서 냉기로 되며 계속하여 냉동실덕트(7)와 냉장실덕트(8)를 통해 냉동실(2)과 냉장실(3)로 적절하게 강제 송풍된다. 이에 따라 냉동실(2)과 냉장실(3)에 보관된 식품은 각각 냉동, 냉장상태로 보관된다.When the circulating fan 6b is operated in the refrigerator configured as described above, air in the freezing compartment 2 and the refrigerating compartment 3 flows into the lower part of the evaporator 6a through the return ducts 9a and 9b. As it passes through, it is cold, and then it is forcedly blown into the freezing chamber 2 and the refrigerating chamber 3 through the freezing chamber duct 7 and the refrigerating chamber duct 8. Accordingly, the foods stored in the freezer compartment 2 and the refrigerating compartment 3 are stored in the frozen and refrigerated state, respectively.
그러나 이러한 종래 냉장고는 냉동실(2) 후방에 마련된 하나의 증발기(6a)와 순환팬(6b)에 의해 냉기가 강제송풍되기 때문에, 내용적이 상대적으로 큰 냉장실(3)에는 냉기가 고르게 공급되지 못한다. 즉, 냉장실(3)은 후벽에 세워져 설치된 냉장실덕트(8)를 통해 냉기가 공급되는데, 순환팬(6)의 강제송풍력이 떨어져 냉장실(3) 전체에 균일하게 공급되지 못하는 단점이 있다.However, in the conventional refrigerator, since the cold air is forcedly blown by one evaporator 6a and the circulation fan 6b provided at the rear of the freezer compartment 2, the cold air is not evenly supplied to the refrigerating compartment 3 having a relatively large internal volume. That is, the refrigerating chamber (3) is supplied with cold air through the refrigerating chamber duct (8) installed on the rear wall, there is a disadvantage that the forced blowing force of the circulation fan 6 is not uniformly supplied to the entire refrigerating chamber (3).
이러한 문제점을 해결하기 위해 최근에는 냉동실과 냉장실에 별도의 증발기를 설치하여 각각의 식품보관 형태에 맞는 최적의 상태를 유지할 수 있게 하는 독립 냉각식 냉장고가 제안되고 있는데, 도 2는 이러한 냉장고 구조를 개략적으로 보인 단면도이다.In order to solve this problem, recently, an independent cooling refrigerator has been proposed to maintain an optimal state for each food storage type by installing separate evaporators in a freezer compartment and a refrigerator compartment, and FIG. 2 schematically illustrates such a refrigerator structure. It is shown in cross section.
독립 냉각식 냉장고는 냉동실(10) 후방과 냉장실(20) 후방에 각각 별도로 냉기공급장치(30,40)가 형성되어 있다. 냉동실(10) 냉기공급장치(30)에는 증발기(31)와 송풍팬(32)이 설치되어 있어서, 냉동실(10)의 공기를 증발기(31)로 흡입하고 이를 지나면서 냉각된 냉기를 냉동실(10)로 다시 강제송풍시킨다. 그리고 냉장실(20) 냉기공급장치(40)는 후벽 상측에 형성되어 있는데, 여기에도 역시 증발기(41), 냉기를 전방측으로 송풍시키는 송풍팬(42)이 증발기(41) 상측에 설치되어 있다. 증발기(41) 전면부에는 냉장실(20) 공기가 흡입되는 흡입구(43)와 냉기가 토출되는 토출구(44)가 형성되어 있으며, 냉기를 냉장실(20) 전체에 적절하게 분배 안내하도록 냉기토출구(46)가 상하로 배열형성된 냉기배분덕트(45)가 후벽면 중심부에 세워져 설치되어 있다. 냉기배분덕트(45) 내부에는 별도의 모터에 의해 회전운동하는 회전날개(47)가 내장되어 있다.In the independent cooling refrigerators, cold air supply devices 30 and 40 are separately formed at the rear of the freezing compartment 10 and the rear of the refrigerating compartment 20, respectively. The freezer compartment 10 is provided with an evaporator 31 and a blower fan 32 in the cold air supply device 30 to suck the air from the freezer compartment 10 into the evaporator 31 and pass the cold air to the freezer compartment 10. Forced air again. The cold air supply device 40 of the refrigerating chamber 20 is formed above the rear wall. Here, the evaporator 41 and the blowing fan 42 for blowing the cold air to the front side are also provided above the evaporator 41. In the front portion of the evaporator 41, the inlet port 43 into which the refrigerating chamber 20 air is sucked and the discharge port 44 through which cold air is discharged are formed, and the cold air discharge port 46 is configured to properly distribute and guide the cold air to the entire refrigerating chamber 20. The cold air distribution duct 45, which is arranged up and down, is installed in the center of the rear wall. Inside the cold air distribution duct 45 is a rotary blade 47 is rotated by a separate motor.
따라서 냉장실(20)의 송풍팬(32)과 회전날개(47)가 회전운동하게 되면, 냉장실(20) 공기는 흡입구(43)를 통해 증발기(41) 하부로 유입되고, 이를 지나면서 생성된 냉기는 송풍팬(32)의 강제 송풍력에 의해 토출구(44)와 냉기분배덕트(45)를 통해 냉장실(20)로 고르게 공급된다. 즉, 일부 냉기는 토출구(44)를 통해 냉장실(20) 상측으로 토출되고, 냉기토출구(46)를 통해 냉기가 냉장실(20) 전체에 균일하게 토출된다. 특히, 냉기배분덕트(45)에 내장된 회전날개(47)가 구동함으로써 냉장실(20) 구석구석 냉기를 고르게 배분하고, 도어(21)를 개방하여도 냉기가 빠져나가지 않도록 회전되며 냉기를 단속해 냉장실(20) 온도가 일정하게 유지된다.Therefore, when the blowing fan 32 and the rotary blade 47 of the refrigerating compartment 20 is rotated, the refrigerating compartment 20 air is introduced into the lower part of the evaporator 41 through the suction port 43, and the cold air generated while passing through the inlet port 43. Is evenly supplied to the refrigerating chamber 20 through the discharge port 44 and the cold air distribution duct 45 by the forced blowing force of the blower fan (32). That is, some of the cold air is discharged to the upper side of the refrigerating chamber 20 through the discharge port 44, and the cold air is uniformly discharged to the entire refrigerating chamber 20 through the cold air discharge port 46. In particular, by driving the rotary blade 47 built in the cold air distribution duct 45, evenly distributed cold air in every corner of the refrigerating chamber 20, rotates so as not to escape the cold air even if the door 21 is opened to intercept cold air The refrigerating chamber 20 temperature is kept constant.
그러나 이러한 독립 냉각식 냉장고는 다음과 같은 문제점이 있다.However, these independent cooling refrigerators have the following problems.
먼저, 냉장실(20) 냉기공급장치(40)는 증발기(41) 전면부 측에 토출구(44)와 흡입구(43)가 인접하게 형성되어 있어서, 토출된 냉기가 열교환이 이루어지지 않은 상태에서 곧바로 흡입구(43)로 재흡입되는 경우가 발생되어 냉동사이클의 열교환효율이 떨어지게 문제점이 있다.First, the cold air supply device 40 of the refrigerating chamber 20 is formed with the discharge port 44 and the suction port 43 adjacent to the front side of the evaporator 41, so that the discharge port immediately flows in the state where the discharged cold air is not heat-exchanged. There is a problem that the case is re-suction to 43 to reduce the heat exchange efficiency of the refrigeration cycle.
그리고, 냉장실(20)의 정온냉각을 위해 냉장실(20) 후벽면에 회전날개(47)가 내장된 별도의 냉기배분덕트(45)를 설치함으로써 제조원가가 상승되는 것은 물론이고, 회전날개(47) 구동으로 인한 전력소비율도 상승된다.In addition, by installing a separate cold air distribution duct 45 having a rotary blade 47 embedded in the rear wall surface of the refrigerating chamber 20 for the constant temperature cooling of the refrigerating chamber 20, the manufacturing cost is increased, as well as the rotary blade 47. Power consumption due to driving also rises.
본 고안은 이러한 문제점을 해결하기 위한 것으로, 본 고안의 주 목적은 냉장실 후벽 중심부에 마련된 증발기를 중심으로 대칭되게 냉기토출구가 다단으로 형성된 토출덕트를 설치하고, 공기흡입구가 최상단에 형성되어 냉장실 공기를 증발기 하부로 안내하는 흡입덕트 역시 증발기 양측단부에 대칭되게 형성함으로써, 냉기배분이 냉장실에 균일하게 이루어져 위치에 따른 온도편차가 발생되지 않으며, 냉동사이클의 열교환효율을 향상시키는 냉장고를 제공하는 것이다.The present invention is to solve this problem, the main purpose of the present invention is to install a discharge duct formed in multiple stages of the cold air outlet symmetrically around the evaporator provided in the center of the rear wall of the refrigerating chamber, the air inlet is formed at the top of the refrigerating chamber air The suction duct guiding to the lower part of the evaporator is also symmetrically formed at both ends of the evaporator, so that the cold air distribution is uniformly formed in the refrigerating chamber so that a temperature deviation according to the position does not occur, thereby providing a refrigerator that improves the heat exchange efficiency of the refrigeration cycle.
본 고안의 부 목적은 토출덕트의 하단부를 흡입덕트를 지나 냉장실 하부까지 연장시킴으로써 냉장실 전체를 균일하게 냉각시키는 냉장고를 제공하는 것이다.A secondary object of the present invention is to provide a refrigerator that uniformly cools the entire refrigerating compartment by extending the lower end of the discharge duct past the suction duct to the bottom of the refrigerating compartment.

It consists of a motor 230, an evaporator cover 240 covering them. The evaporator cover 240 is provided with a cold air outlet 241 for discharging cold air into the freezer compartment 110 and an air inlet 242 for guiding air from the freezer compartment 110 to the lower portion of the evaporator 210.
그리고 냉동실(110)보다 상대적으로 내용적이 크게 형성된 냉장실(120)을 냉각시키는 냉장실용 냉기공급장치(300)는 냉장실(120) 전용적에 걸쳐 균일하게 냉기가 토출되도록 구성되는데, 이를 위해 냉장실(120) 후벽면 중심부위에는 직사각형상의 증발기(310)가 세워져 설치되어 있으며 이것은 단열재(351)와 증발기커버(350)를 통해 덮여져 있다. 증발기(310)의 양측면부에는 생성되는 냉기를 냉장실(120)로 토출안내하는 토출덕트(330)와 냉장실(120) 공기를 증발기(310)로 흡입 안내하는 흡입덕트(340)가 각각 대칭되게 마련되는데, 이것은 냉장실(120) 후벽면 내상과 증발기커버(350)에 의해 이루어진다. 그리고 증발기(310)의 상측 중심부에는 냉장실(120)의 공기를 증발기(310) 하부로 흡입하며 증발기(310)를 지나면서 생성된 냉기를 냉장실(120)로 다시 강제송풍시키는 팬(320)과 모터(321)가 설치되어 있다.In addition, the refrigerating compartment cold air supply device 300 for cooling the refrigerating compartment 120 having a relatively larger internal volume than the freezing compartment 110 is configured to discharge cold air uniformly over the refrigerating compartment 120 exclusively. A rectangular evaporator 310 is installed on the rear wall center and is covered by a heat insulating material 351 and an evaporator cover 350. Discharge ducts 330 for guiding discharged cold air to the refrigerating chamber 120 and suction ducts 340 for suctioning the refrigerating chamber 120 air to the evaporator 310 are provided symmetrically on both sides of the evaporator 310. This is achieved by the inner wall of the refrigerating chamber 120 and the evaporator cover 350. In addition, a fan 320 and a motor for sucking air from the refrigerating chamber 120 into the lower portion of the evaporator 310 and forcibly blowing the generated cool air back to the refrigerating chamber 120 through the evaporator 310 at the upper center of the evaporator 310. 321 is provided.
냉장실(120) 냉기순환을 안내하는 흡입덕트(340)와 토출덕트(330)의 구조를 좀 더 자세히 설명하면 다음과 같다.The structure of the suction duct 340 and the discharge duct 330 for guiding the cold air circulation in detail will be described below.
먼저, 흡입덕트(340)는 하단부(342)가 증발기(310) 하부와 연통되어 있으며, 상단부(341)가 토출덕트(330)와 인접하게 상측방향으로 절곡 연장되어 있다. 즉, 흡입덕트(340)는 증발기(310)을 중심으로 대칭되게 냉장실(120) 후벽 상측까지 연장 형성되며, 이의 상단부(342)에 냉장실(120) 공기가 흡입되도록 흡입구(343)가 형성되어 있다. 이에 따라 열교환작용을 마쳐 냉장실(120) 상측으로 올라간 공기는 흡입구(343)를 통해 증발기(310) 하부로 유입된다.First, the suction duct 340 has a lower end 342 communicating with the lower part of the evaporator 310, and an upper end 341 is bent and extended upwardly adjacent to the discharge duct 330. That is, the suction duct 340 is formed to extend to the upper side of the rear wall of the refrigerating chamber 120 symmetrically around the evaporator 310, and the suction port 343 is formed at the upper end 342 to suck the air in the refrigerating chamber 120. . Accordingly, the air that has completed the heat exchange operation and rises above the refrigerating chamber 120 is introduced into the lower portion of the evaporator 310 through the suction port 343.
그리고 토출덕트(330)는 상단부(331)가 팬(320)과 모터(321)의 설치공간 즉, 증발기(310) 상부와 연통되고, 하단부(332)가 증발기(310) 양측단부를 따라 대칭되게 절곡 연장되어 있다. 토출덕트(330)에는 일정간격 이격된 다수개의 냉기토출구(333)가 상하로 배열형성되어 있다. 이러한 토출덕트(330)는 흡입덕트(340) 상면을 지나 냉장실(120) 후벽면 최하단까지 연장되게 구성되어 냉기가 냉장실(120) 전체에 고르게 토출되는데, 이의 연장구조를 도 5와 6을 참조하여 상세히 설명하면 다음과 같다. 먼저, 증발기(310) 하부에 연통되며 평행하게 가로방향으로 연장된 흡입덕트(340)에는 토출덕트(330) 하단부(332)가 직각방향으로 교차되도록 냉장실(120) 후벽면 내상(121)이 볼록하게 돌출형성되어 있다. 그리고 이러한 교차부위에 플라스틱재로 이루어진 별도의 커플링부재(400)가 설치되어 토출덕트(330) 하단부(332)가 흡입덕트(340)를 지나 냉장실(120) 하단부까지 연장된다. 커플링부재(400)는 양단부가 개방된 관형상으로 마련되어 있어서, 상단부는 흡입덕트(340) 상부측의 토출덕트(330)와 연통되며 하단부는 흡입덕트(340) 하부측의 토출덕트 하단부(332)와 연통된다. 이에 따라 토출덕트(330)는 증발기(310) 측단부와 흡입덕트(340) 상면을 교차하여 냉장실(120) 후벽면 하부까지 연장됨으로써, 냉기가 냉장실(120) 전체에 균일하게 토출된다.The discharge duct 330 has an upper end portion 331 communicating with an installation space of the fan 320 and the motor 321, that is, the upper portion of the evaporator 310, and the lower end portion 332 is symmetrically along both ends of the evaporator 310. It is bent and extended. In the discharge duct 330, a plurality of cold air discharge ports 333 spaced by a predetermined interval are arranged up and down. The discharge duct 330 is configured to extend through the upper surface of the suction duct 340 to the bottom end of the rear wall surface of the refrigerating chamber 120, and thus the cold air is evenly discharged throughout the refrigerating chamber 120. The extension structure thereof will be described with reference to FIGS. 5 and 6. It will be described in detail as follows. First, the inner wall 121 of the rear wall of the refrigerating chamber 120 is convex so that the lower end 332 of the discharge duct 330 intersects at right angles in the suction duct 340 communicating with the lower part of the evaporator 310 and extending in the horizontal direction in parallel. Protruded. In addition, a separate coupling member 400 made of a plastic material is installed at the intersection, and the lower end 332 of the discharge duct 330 extends through the suction duct 340 to the lower end of the refrigerating chamber 120. Coupling member 400 is provided in a tubular shape with both ends open, the upper end is in communication with the discharge duct 330 on the upper side of the suction duct 340, and the lower end is the lower end of the discharge duct 332 on the lower side of the suction duct 340. ). Accordingly, the discharge duct 330 crosses the evaporator 310 side end portion and the upper surface of the suction duct 340 to extend to the lower side of the rear wall of the refrigerating chamber 120, thereby uniformly discharging cold air to the entire refrigerating chamber 120.
다음에는 이와 같이 구성된 본 고안에 따른 냉장고의 작용과 이에 따른 효과를 설명한다.Next will be described the operation and the effects of the refrigerator according to the present invention configured as described above.
먼저, 냉동실용 냉기공급장치(200)의 순환팬(220)이 회전하게 되면 냉동실(110)의 공기는 공기흡입구(242)를 통해 증발기(210) 하부로 유입되며, 증발기(210)를 지나면서 냉기로 변한다. 계속하여 냉기는 순환팬(220)의 강제송풍력에 의해 냉동실(110)로 토출됨으로써 저장식품이 냉동 보관되며, 열교환작용을 마친 공기는 다시 공기흡입구(242)를 통해 증발기(210)로 유입된다.First, when the circulation fan 220 of the freezer compartment cold air supply device 200 rotates, the air of the freezer compartment 110 flows into the evaporator 210 through the air inlet 242 and passes through the evaporator 210. Turns into cold Subsequently, the cold air is discharged to the freezing chamber 110 by the forced blowing force of the circulation fan 220, and thus the stored food is stored frozen. The air which has completed the heat exchange operation is introduced into the evaporator 210 through the air inlet 242 again. .
그리고 냉장실용 냉기공급장치(300)의 팬(320)이 모터(321)에 의해 회전하게 되면, 냉장실(120) 상측에 위치되는 공기는 흡입구(343)를 통해 흡입덕트(340) 내부로 흡입되며, 이를 따라 흐르면서 증발기(310) 하부로 유입된다. 그리고 유입된 공기는 팬(320)의 흡입 송풍력에 의해 증발기(310)를 지나면서 냉기로 변하고, 이것은 토출덕트(330) 상단부(331)측으로 강제로 송풍된다. 이러한 냉기는 토출덕트(330)를 따라 흐르게 되고, 냉기토출구(333)를 통해 냉장실(120)로 토출된다. 이 때, 토출덕트(330)는 증발기(310)의 양측단부를 따라 대칭되고 냉장실(120)의 후벽면 하부까지 연장구성되며 여기에 일정간격 이격되게 상하로 냉기토출구(333)가 배열 형성되어 있기 때문에, 냉장실(120) 내부 및 선반(160)에 칸칸으로 공급되어 식품을 골고루 냉각시킨다.When the fan 320 of the refrigerating compartment cold air supply device 300 is rotated by the motor 321, the air located above the refrigerating compartment 120 is sucked into the suction duct 340 through the suction port 343. , And flows along the bottom of the evaporator 310. In addition, the introduced air is changed into cold while passing through the evaporator 310 by the suction blowing force of the fan 320, which is forcibly blown toward the upper end portion 331 of the discharge duct 330. The cold air flows along the discharge duct 330 and is discharged to the refrigerating chamber 120 through the cold air discharge port 333. At this time, the discharge duct 330 is symmetrical along both side ends of the evaporator 310 and extends to the rear wall surface of the refrigerating chamber 120, and the cold air discharge port 333 is formed up and down to be spaced apart at a predetermined interval. Therefore, the inside of the refrigerating chamber 120 and the shelf 160 is supplied to the compartment to cool the food evenly.
또한 냉장실(120)에서 열교환작용을 마친 공기는 자연대류현상에 의해 냉장실(120) 상측공간으로 올라가며, 이러한 공기는 흡입구(343)와 흡입덕트(340)를 통해 증발기(310)로 다시 유입되어 냉기로 변환되어 지속적으로 순환된다.In addition, the air that has completed the heat exchange in the refrigerating compartment 120 rises to the upper space of the refrigerating compartment 120 by a natural convection phenomenon, and the air flows back into the evaporator 310 through the suction port 343 and the suction duct 340 to be cooled. Is converted into a continuous cycle.
즉, 본 고안에 따른 냉장실용 냉기공급장치(300)는 냉기가 별도의 구동수단없이도 냉장실(120) 전체에 고르게 분산 토출됨으로써, 냉장실(120) 위치에 따른 온도편차가 발생되지 않고 이에 보관된 식품을 균일하게 냉각시킨다. 그리고 열교환작용을 완전히 마친 공기가 냉장실(120) 상측에 위치된 흡입구(343)를 통해 증발기(310)로 다시 유입되기 때문에 냉동사이클의 열교환효율이 향상된다.That is, the cold air supply device 300 for a refrigerating compartment according to the present invention, by dispersing and discharging cold air evenly throughout the refrigerating compartment 120 without a separate driving means, the temperature difference according to the location of the refrigerating compartment 120 does not occur, the food stored therein Cool uniformly. In addition, since the air having completely completed the heat exchange action is introduced back into the evaporator 310 through the suction port 343 located above the refrigerating chamber 120, the heat exchange efficiency of the refrigeration cycle is improved.
이상에서 상세히 설명한 바와 같이, 본 고안에 따른 냉장고는 냉장실 후벽 중심부에 마련된 증발기를 중심으로 대칭되게 공기흡입구가 형성되어 냉장실 공기를 증발기 하부로 안내하는 흡입덕트를 설치하고, 냉기토출구가 다단으로 형성되어 증발기에서 생성된 냉기를 냉장실로 안내하는 토출덕트 역시 양측단부에 대칭되게 마련되어 있다. 이 때, 토출덕트의 하단부는 흡입덕트를 지나 냉장실 후벽면 하부까지 연장되어 있다.As described in detail above, the refrigerator according to the present invention is formed in the air inlet symmetrically around the evaporator provided in the center of the rear wall of the refrigerating chamber to install a suction duct for guiding the refrigerating chamber air to the bottom of the evaporator, the cold air outlet is formed in multiple stages Discharge ducts for guiding the cold air generated in the evaporator to the refrigerating chamber are also provided symmetrically at both ends. At this time, the lower end of the discharge duct extends through the suction duct to the lower part of the rear wall surface of the refrigerating chamber.
따라서 냉기배분이 별도 수단없이도 냉장실 상부에서 하부까지 균일하게 이루어져 위치에 따른 온도편차가 발생되지 않고, 냉장실에서 완전하게 열교환된 공기가 공기흡입구를 통해 증발기로 유입되기 때문에 냉동사이클의 열교환효율이 향상되는 이점이 있다.Therefore, even if the air distribution is uniform from the top to the bottom of the refrigerating chamber without any means, temperature deviation does not occur according to the position, and the heat exchange efficiency of the refrigeration cycle is improved because the air heat exchanged in the refrigerating chamber flows into the evaporator through the air inlet. There is an advantage.
