Abstract
Description
본 발명은, 냉장고에 관한 것으로, 보다 상세하게는, 저장실이 마련된 본체를 구비한 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a refrigerator provided with a main body provided with a storage compartment.
일반적으로 냉장고는 냉동실이나 냉장실과 같은 저장실이 형성된 본체와, 본체의 내부에 마련되어 냉기를 발생시키는 냉동장치와, 저장실의 개구부를 개폐하는 도어를 포함한다.Generally, a refrigerator includes a main body in which a storage compartment such as a freezing compartment or a refrigerating compartment is formed, a refrigerating apparatus provided in the main body to generate cold air, and a door that opens and closes an opening of the storage compartment.
냉동장치는 주로 압축기와 증발기 등으로 구성된 냉동사이클에 의해 냉기를 발생시키는 방법과, 열전반도체소자를 이용하여 냉기를 발생시키는 방법으로 분류된다.Refrigeration apparatuses are mainly classified into a method of generating cold air by a refrigeration cycle composed of a compressor and an evaporator, and a method of generating cold air by using a thermoelectric semiconductor element.
냉동사이클은 기체상태의 냉매를 고온 고압으로 압축하는 압축기와, 압축기로부터 압축된 기체상태의 냉매를 액체상태로 응축하는 응축기와, 액화된 냉매를 저온 저압의 상태로 변환시키는 모세관과, 모세관으로부터 저온 저압으로 액화된 냉매를 기화시키기 위해 증발잠열을 흡수함으로써 주위의 공기를 냉각시키는 증발기로 구성된다.The refrigeration cycle includes a compressor for compressing the gaseous refrigerant at high temperature and high pressure, a condenser for condensing the gaseous refrigerant compressed from the compressor into the liquid state, a capillary tube for converting the liquefied refrigerant into a low temperature low pressure state, and a low temperature from the capillary tube. It consists of an evaporator that cools the surrounding air by absorbing latent heat of evaporation to vaporize the refrigerant liquefied at low pressure.
열전반도체소자는 반도체와 금속의 접합면에 전류가 흐를 때 줄(Joule)열 이외의 열을 발생하고 흡수하는 열전현상을 이용한 것으로서, 전류의 크기와 방향에의하여 흡열과 발열의 양과 방향 조절이 가능하고, 기계적으로 작동하는 부분이 없으며 또한 설치위치나 방향이 그 동작에 영향을 미치지 않는다는 장점이 있어 부하를 가열하거나 냉각시키는 데 널리 사용되고 있다.The thermoelectric semiconductor device uses a thermoelectric phenomenon that generates and absorbs heat other than Joule heat when a current flows through a junction surface of a semiconductor and a metal. The amount and direction of heat absorption and heat generation can be controlled by the magnitude and direction of the current. In addition, there is no mechanically operating part, and the installation position or direction does not affect its operation, and thus it is widely used to heat or cool a load.
종래의 냉장고(101)는 도 1 내지 도 3에 도시된 바와 같이, 저장실(111)이 마련된 본체(110)와, 저장실(111)을 회동 개폐하는 도어(102)와, 저장실(111)의 후방에 마련되어 냉기를 발생시키는 증발기(150)와, 증발기(150)의 상측에 마련되어 냉기를 저장실(111)에 공급하기 위한 원심팬(130)과, 원심팬(130)을 구동시키기 위한 구동모터(140)를 포함한다.1 to 3, the conventional refrigerator 101 includes a main body 110 provided with a storage compartment 111, a door 102 for rotating and opening the storage compartment 111, and a rear of the storage compartment 111. An evaporator 150 provided at the top to generate cold air, a centrifugal fan 130 provided at an upper side of the evaporator 150 to supply cold air to the storage chamber 111, and a drive motor 140 to drive the centrifugal fan 130. ).
본체(110)는 저장실(111)을 형성하는 냉기를 공급받기위한 토출구(114)가 마련된 저장실케이스(113)와, 본체(110)의 외형을 형성하는 본체케이스(115)와, 저장실케이스(113)의 후측과 본체케이스(115) 사이에 마련되어 원심팬(130)에 의해 송풍되는 냉기를 저장실(111)로 안내하는 덕트(120)를 포함한다.The main body 110 includes a storage case 113 provided with a discharge port 114 for receiving cold air forming the storage compartment 111, a main body case 115 forming an external shape of the main body 110, and a storage case 113.

본체케이스(115)의 내측에는 증발기(150)에서 생성된 냉기를 외부공기로부터 단열시키기 위한 단열부재(116)가 마련된다.Inside the body case 115 is provided with a heat insulating member 116 for insulating the cold air generated in the evaporator 150 from the outside air.
덕트(120)는 원심팬(130)을 수용하기 위한 팬수용부(123)와, 원심팬(130)에 의해 송풍되는 냉기를 저장실(111)로 안내하는 덕트부(121)와, 원심팬(130)과 구동모터(140) 사이에 냉기가 원심팬(130)으로 흡입될 수 있게 흡입구가 형성되며 일측이 팬수용부(123)에 결합되고 타측에 구동모터(140)를 지지하기 위한 모터브래킷(127)이 마련된 덕트커버(125)를 포함한다.The duct 120 includes a fan accommodating part 123 for accommodating the centrifugal fan 130, a duct part 121 for guiding cold air blown by the centrifugal fan 130 to the storage compartment 111, and a centrifugal fan ( A suction port is formed between the 130 and the driving motor 140 to allow the cool air to be sucked into the centrifugal fan 130, and one side is coupled to the fan accommodating part 123 and a motor bracket for supporting the driving motor 140 on the other side. And a duct cover 125 provided with 127.
원심팬(130)은 덕트(120)내에 형성된 팬수용부(123)에 수용되어구동모터(140)에 의해 회전되며, 증발기(150)의 주위에 냉각된 냉기를 원심팬(130)의 중앙영역으로 흡입후 원심팬(130)의 회전에 의해 방사방향으로 송풍하여 덕트부(121)를 통해 저장실(111)로 공급하게 된다.The centrifugal fan 130 is accommodated in the fan accommodating part 123 formed in the duct 120, rotated by the driving motor 140, and the cold air cooled around the evaporator 150 in the central region of the centrifugal fan 130. After the suction, the air is blown in the radial direction by the rotation of the centrifugal fan 130 to be supplied to the storage chamber 111 through the duct part 121.
구동모터(140)는 원심팬(130)과 본체케이스(115) 사이에 덕트커버(125)의 모터브래킷(127)에 의해 지지되어 마련되며, 구동모터(140)의 구동축(141)에 의해 원심팬(130)과 결합되어 원심팬(130)을 회전시킨다.The driving motor 140 is provided supported by the motor bracket 127 of the duct cover 125 between the centrifugal fan 130 and the main body case 115, and is centrifugal by the driving shaft 141 of the driving motor 140. Combined with the fan 130 to rotate the centrifugal fan (130).
이러한 구성에 의해, 종래 냉장고의 저장실(111)로 냉기가 공급되는 과정을 살펴보면 다음과 같다. 도 2에 도시된 바와 같이, 구동모터(140)의 작동에 의해 원심팬(130)이 회전하게 된다. 그리고, 원심팬(130)의 회전에 의해 증발기(150)로부터 생성된 냉기가 덕트커버(125)의 흡입구(126)를 통해 흡입된다. 이렇게 흡입된 냉기는 원심팬(130)의 회전에 의해 방사방향으로 송풍되어 팬수용부(123)의 일측에 마련된 덕트부(121)에 안내되어 토출구(114)를 통해 저장실(111)로 공급되게 된다.With this configuration, the process of supplying cold air to the storage compartment 111 of the conventional refrigerator is as follows. As shown in FIG. 2, the centrifugal fan 130 is rotated by the operation of the driving motor 140. Then, the cool air generated from the evaporator 150 by the rotation of the centrifugal fan 130 is sucked through the inlet 126 of the duct cover 125. The sucked cold air is blown in the radial direction by the rotation of the centrifugal fan 130 to be guided to the duct part 121 provided on one side of the fan accommodating part 123 to be supplied to the storage chamber 111 through the discharge port 114. do.
그리고, 이러한 종래 냉장고는, 같은 크기의 본체(110)에서 저장실(111)의 공간을 최대한 확보하기 위하여 저장실케이스(113)를 본체케이스(115)에 가능한 근접시키게 된다.In the conventional refrigerator, the storage compartment case 113 is as close as possible to the body case 115 in order to maximize the space of the storage compartment 111 in the main body 110 of the same size.
그런데, 이러한 종래 냉장고는 저장실케이스(113)와 본체케이스(115) 사이를 최대한 근접시키기 때문에, 도 2에 도시된 바와 같이, 냉기의 유동이 가장 많은 구동모터(140)가 위치하는 부위에 단열부재의 두께가 얇아지게 되어 냉기의 온도가 상승하게 되는 문제점이 있다.By the way, since the conventional refrigerator is as close as possible between the storage case 113 and the main body case 115, as shown in Figure 2, the heat insulating member in the position where the drive motor 140 is the most flow of cold air is located. There is a problem that the thickness of the thinner is the temperature of the cold air rises.
그리고, 이러한 종래 냉장고는 원심팬(130)으로 흡입되는 냉기가 원심팬(130)의 후방에 마련된 구동모터(140)와 구동모터(140)를 지지하기 위한 모터브래킷(127)에 의해 간섭되어 원심팬(130)으로 용이하게 유입되지 못할 뿐만 아니라, 냉기의 유동 간섭에 의한 소음이 발생하는 문제점이 있다.In the conventional refrigerator, the cold air sucked into the centrifugal fan 130 is interfered by the motor bracket 127 for supporting the driving motor 140 and the driving motor 140 provided at the rear of the centrifugal fan 130. Not only does not easily flow into the fan 130, there is a problem that noise caused by the flow interference of cold air.
따라서, 본 발명의 목적은, 냉기의 유동을 용이하게 할 수 있을 뿐만 아니라, 냉기의 유동에 의한 소음을 줄일 수 있는 냉장고를 제공하는 것이다.It is therefore an object of the present invention to provide a refrigerator which can not only facilitate the flow of cold air but also reduce the noise caused by the flow of cold air.
그리고, 본 발명의 다른 목적은, 본체케이스의 내측에 단열보강부재를 더 마련하여, 냉기의 온도가 상승하는 것을 방지할 수 있는 냉장고를 제공하는 것이다.In addition, another object of the present invention is to provide a refrigerator that can further provide an insulation reinforcing member inside the main body case, to prevent the temperature of the cold air rises.
