Description
본 발명은 냉장고에 관한 것으로 특히 냉장고 냉동실내로 토출되는 냉기를 정면쪽으로 안내하는 냉장고 냉동실내의 냉기안내장치에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a cold air guiding apparatus in a refrigerator freezer compartment for guiding cold air discharged into the refrigerator freezer compartment to the front side.
종래의 냉장고는 도1과 같이 냉동실(1)과 냉장실(2)이 형성되고, 상기 냉동실(1)과 냉장실(2)에 냉기를 공급하는 냉동싸이클은 압축기(3)에 의하여 냉매를 흡입하여 압축하고, 압축된 고온고압의 냉매는 응축기에 의하여 외부공기와 열교환시켜 고압의 과냉액냉매로 응축시키며, 응축된 고압의 과냉매는 팽창변에 의하여 팽창되어 저온저압의 냉매로 감압되고, 감압된 저온저압의 냉매는 증발기(4)에 의하여 주변의 더운공기와 열교환시켜 고온고압의 냉매로 증발시키도록 구성되였다.In the conventional refrigerator, as shown in FIG. 1, a freezing compartment 1 and a refrigerating compartment 2 are formed, and a freezing cycle for supplying cold air to the freezing compartment 1 and the refrigerating compartment 2 is compressed by sucking a refrigerant by a compressor 3. The compressed high-temperature and high-pressure refrigerant is condensed into a high-pressure subcooled refrigerant by exchanging heat with external air by a condenser. The condensed high-pressure supercoolant is expanded by an expansion valve to be decompressed to a low-temperature and low-pressure refrigerant, The refrigerant was configured to evaporate into a refrigerant of high temperature and high pressure by heat exchange with surrounding hot air by the evaporator (4).
상기 증발기(4)에 의하여 열교환되어 형성된 냉기는 팬(5)에 의하여 냉기취출그릴(6)를 통해 냉동실(1)로 유입되도록 구성되였다.The cold air formed by heat exchange by the evaporator 4 is configured to be introduced into the freezing chamber 1 through the cold air extraction grill 6 by the fan 5.
이와같이 구성된 상태에서 냉장고가 가동되면 증발기(4)에 의하여 열교환된 냉기가 팬(5)에 의하여 냉기취출그릴(6)을 통하여 냉동실(1)로 유입되어 냉동실(1)에 보관중인 음식물을 냉동시켜 보관하였다.When the refrigerator is operated in the state configured as described above, the cold air heat exchanged by the evaporator 4 is introduced into the freezer compartment 1 through the cold air extraction grill 6 by the fan 5 to freeze the food stored in the freezer compartment 1. Stored.
이때, 냉동실(1)내로 유입된 냉기유로는 냉동실(1)의 뒷면 위에서 뿜어져 아래로 내려 오도록 형성되어져 있다.At this time, the cold air flow flowing into the freezing chamber 1 is formed to be sprayed on the back of the freezing chamber 1 to descend.
따라서, 냉동실(1)내에 음식물이 꽉 채워져 있을 때에는 냉기가 보관중인 음식물에 막혀 골고루 분산되지 못하기 때문에 보관중인 식품이 균일하게 냉동이 이루지지 못하는 문제점이 발생하였다.Therefore, when the food is completely filled in the freezer compartment 1, since the cold air is blocked by the food being stored and is not evenly distributed, there is a problem in that the food stored is not uniformly frozen.
또한, 식품이 냉동실에 가득찼을 때는 식품이 냉기순환용 팬(5)의 저항으로 작용하여 소비전력의 증가를 초래하는 문제점이 발생하였다.In addition, when the food is filled in the freezer compartment, the food acts as a resistance of the cold air circulation fan 5 to cause an increase in power consumption.
본 발명은 이러한 점을 감안하여 발명한 것으로서 냉동실내의 상면에 냉기를 앞으로 안내할 수 있는 냉기안내수단를 구비함으로서 보관중인 음식물의 냉동이 골고루 이루어지도록 하고, 또한 냉기순환용 팬의 저항을 감소시켜 소비전력을 감소시킬 수 있도록 하는데 목적이 있다.The present invention has been invented in view of this point, and by having a cold air guiding means for guiding cold air forward on the upper surface of the freezer compartment, the freezing of the food being stored is made evenly, and also reducing the resistance of the cold air circulation fan to consume power consumption. The purpose is to reduce the

본 발명 냉장고 냉동실내의 냉기안내장치를 도2 내지 도4에 의하여 상세히 설명하면 다음과 같다.The cold air guide device in the refrigerator freezer of the present invention will be described in detail with reference to FIGS.
냉동실(101)에 냉기를 공급하는 냉동싸이클은 압축기에 의하여 냉매를 흡입하여 압축하고, 압축된 고온고압의 냉매는 응축기에 의하여 외부공기와 열교환시켜 고압의 과냉액냉매로 응축시키며, 응축된 고압의 과냉매는 팽창변에 의하여 팽창되어 저온저압의 냉매로 감압되고, 감압된 저온저압의 냉매는 증발기(102)에 의하여 주변의 더운공기와 열교환시켜 고온고압의 냉매로 증발시키도록 구성되고, 상기 증발기(102)에 의하여 열교환되어 형성된 냉기는 팬(103)에 의하여 냉기취출그릴(104)를 통해 냉동실(101)로 유입되도록 구성된 것에 있어서,The refrigeration cycle for supplying cold air to the freezer compartment 101 sucks and compresses the refrigerant by a compressor, and the compressed high temperature and high pressure refrigerant is condensed with high pressure subcooled refrigerant by heat exchange with external air by a condenser. The supercoolant is expanded by an expansion valve to be decompressed to a low temperature low pressure refrigerant, and the low temperature low pressure refrigerant is configured to evaporate into a high temperature high pressure refrigerant by exchanging heat with surrounding hot air by an evaporator 102, and the evaporator 102 In the heat exchange formed by the heat exchanger) configured to be introduced into the freezing chamber 101 through the cold air extraction grill 104 by the fan 103,
증발기(102)에서 열교환되고 냉기취출그릴(104)을 통하여 냉동실(101)로 취출된 냉기의 일부가 냉동실(101)의 전면으로 이동되도록 안내하는 냉기통로(105)가 형성된 냉기안내덕트(106)를 냉동실(101)에 구비하였다.The cold air duct 106 formed with a cold air passage 105 for guiding the heat exchange in the evaporator 102 and guiding a portion of the cold air taken out of the freezing chamber 101 through the cold air drawing grill 104 to the front surface of the freezing chamber 101. Was provided in the freezer compartment (101).
그리고, 상기 냉기취출그릴(104)을 통하여 취출되는 냉기가 상부로 취출되도록 상방향으로 가이드(107)를 구비하였다.Then, the guide 107 is provided in the upward direction so that the cold air drawn out through the cold air drawing grill 104 is taken out.
상기 가이드(107)는 냉기취출그릴(104)의 1/3정도로 구성하는 것이 더욱 효과적 이다.The guide 107 is more effective to configure about 1/3 of the cold air draw grill 104.
그리고, 상기 냉기안내덕트(106)는 플라스틱 등의 합성수지로 이루어졌다.The cold air duct 106 is made of synthetic resin such as plastic.
이와같이 구성된 상태에서 냉장고가 가동되면 증발기(102)에 의하여 열교환된 냉기가 팬(103)에 의하여 냉기취출그릴(104)를 통하여 냉동실(101)로 유입되어 냉동실(101)에 보관중인 음식물을 냉동시켜준다.When the refrigerator is operated in the state configured as described above, the cold air heat exchanged by the evaporator 102 is introduced into the freezer compartment 101 through the cold air extraction grill 104 by the fan 103 to freeze food stored in the freezer compartment 101. give.
이때, 냉동실(101)내로 유입된 냉기유로는 냉기취출그릴(104)에 형성된 가이드(107)에 의하여 상부로 취출되어 냉동실(101)의 상면에 부착된 냉기안내덕트(106)에 의하여 형성된 냉기통로(105)를 통하여 전면으로 안내된다.At this time, the cold air flow path introduced into the freezing chamber 101 is drawn upward by the guide 107 formed in the cold air drawing grill 104 and formed by the cold air duct 106 attached to the upper surface of the freezing chamber 101. Guided to the front through 105.
따라서, 냉동실(101)로 유입된 냉기는 냉동실(101)에 골고루 퍼지기 때문에 냉동실(101)에 보관중인 음식물의 냉동이 골고루 잘 이루어지게 된다.Therefore, since the cold air introduced into the freezer compartment 101 is evenly spread in the freezer compartment 101, the freezing of food stored in the freezer compartment 101 is evenly performed.
그리고, 냉기취출그릴(104)의 상부에 형성된 가이드(107)의 출구가 상향되게 구성함으로서 취출된 냉기가 냉기통로(105)로의 유입이 잘 이루어지기 때문에 냉기가 전면으로 안내가 잘이루어진다.Further, since the outlet of the guide 107 formed on the upper portion of the cold air extraction grill 104 is configured to be upward, the cold air is easily introduced into the cold air passage 105, and thus the cold air is well guided to the front surface.
이와같은 본 발명은 냉동실의 뒷편에서 토출된 냉기가 냉기통로를 통하여 전면으로의 안내가 잘 이루어지기 때문에 냉동실내에 보관중인 음식물의 냉동이 고르게 잘 이루어지는 효과가 있고, 또한 음식물이 냉동실에 가득 찼을 때 냉기가 보관중인 음식물로 인한 저항으로 팬 전력의 소비가 증가되는 것을 방지하여 안정된 전력 소비값을 얻을 수 있는 효과가 있다.In the present invention, since the cold air discharged from the rear side of the freezer compartment is well guided to the front through the cold air passage, the freezing of food stored in the freezer compartment is evenly performed, and the cold air is filled when the food is filled in the freezer compartment. It is effective to obtain a stable power consumption value by preventing the consumption of fan power is increased by the resistance due to the food in storage.
