Abstract
본 발명은 냉장고의 부압제거장치에 관한 것으로서, 특히 배수호스의 일측에 보조흡입관을 형성하고, 이 보조흡입관의 단부에는 공기의 유동에 따라 공기흡입구를 개방시키는 개폐편이 장착된 밸브체를 결합하되, 상기 밸브체는 내측에 삽입되는 밸브커버에 의해 고정됨에 따라 냉장고가 가동중인 상태에서는 다량의 공기가 고내로 유입되는 것을 방지하여 고내의 온도상승을 예방할 수 있으며, 도어 개방시에는 외부의 공기를 신속하게 고내로 유입시켜 빠른 시간내에 고내·외의 압력차를 해소시킴에 따라 도어를 원활하게 개방시킬 수 있다.The present invention relates to a negative pressure removing device of a refrigerator, and in particular, an auxiliary suction pipe is formed on one side of a drain hose, and an end of the auxiliary suction pipe is coupled to a valve body equipped with an opening and closing piece for opening an air suction port according to the flow of air. Since the valve body is fixed by a valve cover inserted into the inside of the refrigerator, a large amount of air is prevented from entering the inside of the refrigerator while the refrigerator is in operation, thereby preventing a temperature increase in the inside of the refrigerator. The door can be opened smoothly by relieving the pressure difference between the inside and the outside in a short time by flowing into the inside.
Description
본 발명은 냉장고의 부압제거장치에 관한 것으로서, 특히 도어 개방시 고내로 외부공기를 신속하게 유입시켜 냉장고 가동중에 발생된 고내·외의 압력차를 빠른 시간내에 해소시킴에 따라 냉장고 도어를 원활하게 개방시킬 수 있는 냉장고의 부압제거장치에 관한 것이다.The present invention relates to a negative pressure removing device of a refrigerator, and in particular, by quickly introducing external air into the refrigerator when the door is opened, the refrigerator door can be smoothly opened as the internal and external pressure differences generated during operation of the refrigerator are solved quickly. It relates to a negative pressure removing device of the refrigerator.
일반적으로, 냉장고는 압축기, 응축기, 팽창밸브 및 증발기의 냉동사이클에 따른 냉매가스의 증발잠열을 이용하여 고내의 온도를 저온으로 유지시켜 음식물의 신선도를 보존하는 장치이다.In general, a refrigerator is a device for preserving the freshness of food by maintaining the temperature in the refrigerator at a low temperature using the latent heat of evaporation of the refrigerant gas according to the refrigeration cycle of the compressor, the condenser, the expansion valve and the evaporator.
즉, 압축기가 냉매가스를 압축하여 포화압력까지 냉매가스의 압력과 온도를 상승시켜 주면 응축기가 물이나 공기를 이용하여 고온·고압의 냉매가스가 갖고 있는 열을 흡수하여 냉매가스를 응축·액화시킨다. 이와같이 응축·액화된 냉매가스는 팽창밸브의 교축작용에 의해 온도와 압력이 낮아지고, 이 냉매가스가 증발기에서 증발하면서 보관중인 음식물로 부터 열을 흡수하여 냉동작용을 수행하게 된다.That is, when the compressor compresses the refrigerant gas and raises the pressure and temperature of the refrigerant gas to the saturation pressure, the condenser absorbs the heat of the refrigerant gas of high temperature and high pressure by using water or air to condense and liquefy the refrigerant gas. . The refrigerant gas condensed and liquefied is lowered in temperature and pressure by the throttling action of the expansion valve, and the refrigerant gas is evaporated in the evaporator to absorb heat from the stored food and perform the freezing action.
도 3은 상기와 같이 음식물의 신선도를 보존하기 위해 사용되는 일반적인 냉장고를 나타낸 측단면도이다.Figure 3 is a side cross-sectional view showing a typical refrigerator used to preserve the freshness of the food as described above.
도면에 도시된 바와같이, 냉장고 본체(100)는 격벽(130)에 의해 음식물을 냉동 보관하는 냉동실(110)과 냉장 보관하는 냉장실(120)로 분리되어 있는데, 상기 냉동실(110)의 일측에는 피냉각 물체로 부터 열을 흡수하는 증발기(140)가 장착되어 있고, 방음 및 방진을 위하여 케이스내에 밀폐되게 수납되어 있는 압축기(150)가 냉장고 본체(100)의 하부에 설치되어 있다.As shown in the figure, the refrigerator main body 100 is divided into a freezing compartment 110 for freezing and storing food and a refrigerating compartment 120 for storing food by the partition wall 130, and at one side of the freezing compartment 110 An evaporator 140 that absorbs heat from the cooling object is mounted, and a compressor 150 that is enclosed in a case for soundproofing and dustproofing is installed in the lower part of the refrigerator main body 100.
한편, 냉장고 본체(100)는 음식물이 보관되는 캐비티를 형성하는 합성수지재의 내상(160)과, 소정의 강도를 갖는 철판재의 외상(180) 및 상기 내상(160)과 외상(180) 사이에 형성된 공간부에 발포되어 단열층을 형성하는 우레탄 부재(170)로 구성되어 있다.Meanwhile, the refrigerator main body 100 includes an inner wound 160 of a synthetic resin material forming a cavity in which food is stored, an outer wound 180 of an iron plate having a predetermined strength, and a space formed between the inner wound 160 and the outer wound 180. It consists of the urethane member 170 which foams in a part and forms a heat insulation layer.
상기한 바와같이 증발기(140)는 피냉각 물체로 부터 열을 흡수하는데, 이때 냉매가스와 고내의 온도차에 의해 발생된 수분이 증발기(140)에서 동결되어 성에를 형성한다. 이와같이 증발기(140)에 성에가 형성되면 냉장고의 효율이 저하됨에 따라 일반적으로 증발기(140)의 하부에는 성에를 제거하기 위한 제상히터(도시안됨)가 설치되어 있다.As described above, the evaporator 140 absorbs heat from the object to be cooled. At this time, moisture generated by the temperature difference between the refrigerant gas and the refrigerator is frozen in the evaporator 140 to form frost. Thus, when frost is formed in the evaporator 140, as the efficiency of the refrigerator decreases, a defrost heater (not shown) is generally installed at the lower portion of the evaporator 140 to remove frost.
따라서, 제상히터에서 발생된 열에 의해 증발기(140)의 성에가 녹아 제상수가 생성되면, 이 제상수는 배수받이(190)와 배수호스(200)를 통해 냉장고의 하부에 장착된 증발명(210)으로 배출된다.Therefore, when the frost of the evaporator 140 is melted by the heat generated in the defrost heater and the defrost water is generated, the defrost water is evaporated name 210 mounted on the lower part of the refrigerator through the drain pan 190 and the drain hose 200. To be discharged.
도 4는 상기와 같이 제상수를 증발명(210)으로 배출하는 배수호스(200)의 단부를 확대하여 나타낸 도면으로, 단열재인 우레탄 부재 사이에 매설되는 플렉시블한 원형의 주룸관인 배수호스(200)의 단부에는 원형의 배수캡(202)이 결합되어 있다.4 is an enlarged view of an end portion of the drain hose 200 for discharging the defrost water to the evaporation name 210 as described above. The drain hose 200 is a flexible circular main room tube embedded between the urethane members as the heat insulating material. At the end of the circular drain cap 202 is coupled.
상기 배수캡(202)에는 소정의 크기를 갖는 배수구(203)가 형성되어 있는데, 이 배수구(203)는 일반적으로 배수호스(200)의 단부에 형성된 배수구(201) 보다 작게 형성되어 있다. 이는 배수호스(200)를 통해 가동중인 냉장고의 고내로 다량의 공기가 유입되어 고내의 온도를 상승시키는 것을 방지하기 위함이다.The drain cap 202 is formed with a drain hole 203 having a predetermined size, which is generally formed smaller than the drain hole 201 formed at the end of the drain hose (200). This is to prevent a large amount of air is introduced into the refrigerator of the operating refrigerator through the drain hose 200 to increase the temperature in the refrigerator.
그러나, 상기와 같은 종래의 배수호스는 배수구의 크기가 작아 도어 개방시 고내로 원활하게 공기를 유입시키지 못함에 따라 냉장고 가동시 발생된 고내·외의 압력차를 신속하게 해소시키지 못한다. 이에따라, 냉장고 도어가 부압으로 인해 원활하게 개방되지 않는다는 문제점이 있었다.However, the conventional drain hose as described above does not quickly eliminate the pressure difference between the inside and the outside of the refrigerator due to the small size of the drain hole, which does not allow air to smoothly flow into the inside of the door when the door is opened. Accordingly, there has been a problem that the refrigerator door does not open smoothly due to negative pressure.
또한, 상기와 같은 문제점을 해결하기 위해 배수호스의 단부에 결합되는 배수캡의 배수구 크기를 확대하는 경우에는 다량의 공기가 가동중인 냉장고의 고내로 유입되어 고내의 온도를 상승시킬 수 있다는 문제점이 있다.In addition, in order to solve the above problems, when the size of the drain hole of the drain cap coupled to the end of the drain hose is enlarged, there is a problem that a large amount of air flows into the refrigerator of an operating refrigerator to increase the temperature in the refrigerator. .
이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 냉장고가 가동중이면 다량의 공기가 고내로 유입되는 것을 방지하여 고내의 온도상승을 예방하고, 도어 개방시에는 외부의 공기를 신속하게 고내로 유입시켜 빠른 시간내에 고내·외의 압력차를 해소시킴에 따라 도어를 원활하게 개방시킬 수 있는 냉장고의 부압제거장치를 제공하는 것을 그 목적으로 한다.Therefore, the present invention was invented to solve the above problems, and when the refrigerator is in operation, it prevents a large amount of air from entering the interior to prevent the temperature rise in the interior, and when the door is opened quickly to the outside air It is an object of the present invention to provide a negative pressure removing device of a refrigerator capable of smoothly opening a door by eliminating the pressure difference between the inside and the outside of the refrigerator in a short time.
상기와 같은 목적을 달성하기 위하여 본 발명은, 냉장고의 제상수 배수호스에 있어서, 상기 배수호스의 일측에 보조흡입관을 형성하고, 이 보조흡입관의 단부에는 공기의 유동에 따라 공기흡입구를 개방시키는 개폐편이 장착된 밸브체를 결합하되, 상기 밸브체는 내측에 삽입되는 밸브커버에 의해 고정되는 것을 특징으로 한다.In order to achieve the above object, the present invention, in the defrost water draining hose of the refrigerator, the auxiliary suction pipe is formed on one side of the drain hose, the end of the auxiliary suction pipe opening and closing to open the air intake in accordance with the flow of air The valve body is coupled to one side, the valve body is characterized in that it is fixed by a valve cover inserted into the inside.

이하, 본 발명의 바람직한 일실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 부압제거장치를 나타낸 단면도로, 제상수를 증발명으로 배출하는 배수호스(10)의 일측에는 냉장고의 부압을 제거하기 위해 외부공기를 흡입하는 보조흡입관(11)이 형성되어 있는데, 이 보조흡입관(11)은 제상수가 유입되지 않도록 상방향으로 형성되어 있다.1 is a cross-sectional view showing a negative pressure removing device according to the present invention, one side of the drain hose 10 for discharging the defrost water in the evaporation name is formed with an auxiliary suction pipe 11 for sucking the outside air to remove the negative pressure of the refrigerator This auxiliary suction pipe 11 is formed in an upward direction so that defrost water does not flow.
한편, 보조흡입관(11)의 단부에는 공기의 유동을 제한하는 개폐편(30)이 장착된 밸브체(20)가 결합되어 있는데, 밸브체(20)의 일측에는 공기흡입구(21)가 형성되어 있고, 이 공기흡입구(21)의 내측 상부에는 상기 개폐편(30)을 고정시키는 고정구(22)가 형성되어 있다.On the other hand, the end of the auxiliary suction pipe 11 is coupled to the valve body 20 is equipped with an opening and closing piece 30 for restricting the flow of air, the air inlet 21 is formed on one side of the valve body 20 In addition, a fastener 22 for fixing the opening and closing piece 30 is formed at an inner upper portion of the air suction port 21.
개폐편(30)에는 밸브체(20)의 고정구(22)에 대응하는 결합홀(31)이 형성되어 있으며, 공기의 유동에 따라 개폐편(30)이 원활하게 개폐되도록 개폐편(30)의 소정부위에는 홈부(32)가 형성되어 있다.The opening and closing piece 30 is formed with a coupling hole 31 corresponding to the fixture 22 of the valve body 20, and the opening and closing piece 30 so as to open and close smoothly according to the flow of air. The groove part 32 is formed in the predetermined part.
밸브체(20)의 내측에 삽입되는 밸브커버(40)에는 밸브체(40)의 내측면에 형성된 고정돌기(23)에 대응하는 걸림턱(42)이 형성되어 있으며, 또한 밸브체(40)의 고정구(22)에 대응하는 고정홈(41)이 형성되어 있는데, 이 고정홈(41)은 밸브체(40)의 고정구(22)에 결합된 개폐편(30)이 고정구(22)로 부터 이탈되지 않도록 고정한다.In the valve cover 40 inserted into the valve body 20, a locking jaw 42 corresponding to the fixing protrusion 23 formed on the inner surface of the valve body 40 is formed, and the valve body 40 is also provided. Fixing groove 41 is formed corresponding to the fixture 22 of the fixing groove 41 is the opening and closing piece 30 coupled to the fixture 22 of the valve body 40 from the fixture 22 Secure it so that it does not fall off.
따라서, 냉장고가 가동중인 경우에는 개폐편(30)이 공기흡입구(21)를 밀폐시키므로 제상수는 배수호스(10)의 배수캡(도시안됨)을 통해 배출되고, 고내로는 외부의 공기가 유입되지 않음에 따라 고내의 온도상승을 방지할 수 있다.Therefore, when the refrigerator is in operation, the opening and closing piece 30 seals the air intake 21 so that the defrost water is discharged through the drain cap (not shown) of the drain hose 10, and outside air flows into the interior of the refrigerator. As a result, it is possible to prevent the temperature rise in the refrigerator.
그러나, 도어가 개방되는 경우에는 개폐편(30)이 공기의 흐름에 따라 내측으로 밀려 들어감에 따라 공기흡입구(21)가 개방된다. 이로인해, 다량의 공기가 순간적으로 고내로 유입됨에 따라 고내·외의 압력차는 단시간내에 해소되어 도어는 원활하게 개방된다.However, when the door is opened, the air inlet 21 is opened as the opening and closing piece 30 is pushed inward as the air flows. Due to this, as a large amount of air flows into the air at once, the pressure difference between the inside and the outside of the air is resolved within a short time, and the door is opened smoothly.
상기와 같이 고내로 공기가 유입된 후, 더 이상의 공기의 유동이 없으면 개폐편(30)은 자체의 하중에 원상 복귀하게 된다. 따라서, 다량의 외부공기가 고내로 유입되어 고내온도를 상승시키거나 저온의 고내공기가 고외로 배출되는 것을 방지할 수 있다.After the air is introduced into the air as described above, if there is no more flow of air, the opening and closing piece 30 is returned to its original load. Therefore, it is possible to prevent a large amount of external air flows into the air to increase the internal temperature or discharge the low-temperature high air into the air.
상기와 같이 본 발명은, 냉장고가 가동중인 경우에는 외부의 공기가 고내로 유입되는 것을 방지함에 따라 고내의 온도상승을 방지할 수 있으며, 도어 개방시에는 외부의 공기를 신속하게 고내로 유입시켜 빠른 시간내에 고내·외의 압력차를 해소시킴에 따라 도어를 원활하게 개방시킬 수 있다.As described above, the present invention, when the refrigerator is in operation to prevent the outside air is introduced into the interior, it is possible to prevent the temperature rise in the interior, and when the door is opened by quickly introducing the outside air into the interior quickly The door can be opened smoothly by eliminating the pressure difference between the inside and the outside within the time.
본 발명은 도면에 도시된 일실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 당해 기술분야에 통상의 지식을 지닌 자라면 이로부터 다양한 변형 및 균등한 타실시예가 가능하다는 점을 이해할 것이다. 따라서, 본 발명의 진정한 기술적 보호범위는 첨부된 특허청구의 범위에 의해서만 정해져야 할 것이다.Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
