Abstract

PURPOSE: A negative pressure removing device of a refrigerator is provided to prevent compartment temperatures from rising by inhibiting a large amount of air from flowing into compartments during running of a refrigerator and to open a refrigerator door easily by removing pressure difference within a short time. CONSTITUTION: An auxiliary intake pipe(11) is formed on a side of a feed hose(10) to suck external air for removing negative pressure of a refrigerator. A valve body(20) having an open-and-shut member(30) is coupled to the auxiliary intake pipe. An air intake port(21) is formed on a side of the valve body, and a fixing unit(22) is protruded up to the air intake port. When a door is opened, the open-and-shut member is pushed to inside and the air intake port is opened. Thereby, a large amount of air flows into a compartment in a moment. Pressure difference between inside and outside of the compartment is offset within a short time. If the air does not flow any longer, the open-and-shut member returns to the original position. Therefore, external air does not raise compartment temperature or low-temperature compartment air is not discharged out of the compartment.

Description

냉장고의 부압제거장치 (An apparatus for eliminating the pressure discrepancy between the inner and the outer of a refrigerator)An apparatus for eliminating the pressure discrepancy between the inner and the outer of a refrigerator

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 방지하고, 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, a large amount of air is prevented from entering the interior to prevent a temperature rise in the interior, and when the door is opened, outside air is quickly 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 외부공기가 흡입되는 보조흡입관을 형성하고, 이 보조흡입관의 단부에는 공기의 유동에 따라 공기흡입구를 개폐시키는 개폐편이 장착된 밸브체를 결합하되, 상기 밸브체에는 개폐편의 결합홀에 삽입되는 고정구가 형성되어 있으며, 상기 밸브체의 내측에는 밸브체의 고정구와 맞물리는 고정홈이 형성된 밸브커버가 삽입되는 것을 특징으로 한다.In order to achieve the above object, the present invention, in the defrost water drainage hose of the refrigerator, to form an auxiliary suction pipe in which external air is sucked on one side of the drain hose, the air in accordance with the flow of air at the end of the auxiliary suction pipe Coupling the valve body is equipped with an opening and closing piece for opening and closing the inlet, the valve body is formed with a fastener is inserted into the coupling hole of the opening and closing piece, the valve body is formed inside the valve body formed with a fixing groove for engaging the fixture of the valve body Characterized in that is inserted.

이하, 본 발명의 바람직한 일실시예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 따른 부압제거장치를 나타낸 단면도로, 제상수를 증발명으로 배출하는 배수호스(10)의 일측에는 냉장고의 부압을 제거하기 위해 외부공기를 흡입하는 보조흡입관(11)이 형성되어 있는데, 상기 보조흡입관(11)을 통해 제상수가 유출되지 않도록 상방으로 경사지게 보조흡입관(11)이 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 The auxiliary suction pipe 11 is formed to be inclined upward so that defrost water does not flow out through the auxiliary suction pipe 11.

한편, 보조흡입관(11)의 단부에는 공기의 유입을 제한하는 개폐편(30)이 장착된 밸브체(20)가 결합되어 있는데, 상기 밸브체(20)의 일측에는 공기흡입구(21)가 형성되어 있고, 이 공기흡입구(21)의 상측에는 개폐편(30)이 고정되는 고정구(22)가 불출되게 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 limiting the inflow of air, the air inlet 21 is formed on one side of the valve body 20 The fastener 22 to which the opening-closing piece 30 is fixed is formed in the upper side of this air suction opening 21.

아울러, 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 내면에는 횡방향으로 홈부(32)가 형성되어 있다.In addition, the opening and closing piece 30 is formed with a coupling hole 31 corresponding to the fixture 22 of the valve body 20, the opening and closing piece 30 so that the opening and closing piece 30 is smoothly opened and closed in accordance with the flow of air. The groove portion 32 is formed on the inner surface of the cross section in the lateral direction.

상기 밸브체(20)의 내측에 삽입되는 밸브커버(40)에는 밸브체(20)의 내측면에 형성된 고정돌기(23)에 대응하는 걸림턱(42)이 형성되어 있으며, 또한 밸브체(20)의 고정구(22)가 삽입되는 고정홈(41)이 형성되어 있는데, 이 고정홈(41)은 밸브체(20)의 고정구(22)에 결합된 개폐편(30)이 고정구(22)로부터 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 20 is formed, and the valve body 20 is formed. Fixing groove 41 is inserted into the fixture 22 of the () is formed, the fastening groove 41 is the opening and closing piece 30 coupled to the fixture 22 of the valve body 20 from the fixture 22 Secure it so that it does not fall off.

따라서, 밸브체(20)의 고정구(22)가 개폐편(30)의 결합홀(31)에 삽입되도록 개폐편(30)을 밸브체(20)에 장착하고, 상기 밸브체(20)의 내측으로 밸브커버(40)를 삽입하면 고정돌기(23)에 의해 밸브커버(40)는 밸브체(20)로부터 분리되지 않으며, 또한 밸브커버(40)의 고정홈(41)과 밸브체(20)의 고정구(22)가 맞물림에 따라 개폐편(30)은 고정구(22)로 부터 이탈되지 않는다.Therefore, the opening / closing piece 30 is attached to the valve body 20 so that the fixture 22 of the valve body 20 is inserted into the coupling hole 31 of the opening / closing piece 30, and the inner side of the valve body 20 is installed. When the valve cover 40 is inserted into the valve cover 40, the valve cover 40 is not separated from the valve body 20 by the fixing protrusion 23, and the fixing groove 41 and the valve body 20 of the valve cover 40 are not separated. As the fixture 22 is engaged, the opening and closing piece 30 is not separated from the fixture 22.

가동중인 냉장고의 보조흡입관(11)에 상기와 같이 개폐편(30)과 밸브커버(40)가 결합된 밸브체(20)를 결합하면 제상수는 배수호스(10)의 배수캡(도시안됨)을 통해 배출되고, 개폐편(30)이 밸브체(20)의 공기흡입구(21)를 밀폐시킴에 따라 고내로는 외부의 공기가 유입되지 않아 고내의 온도상승은 방지된다.When the valve body 20 coupled with the opening / closing piece 30 and the valve cover 40 is coupled to the auxiliary suction pipe 11 of the refrigerator in operation, the defrost water is drained from the drain hose 10 (not shown). As it is discharged through, the opening and closing piece 30 seals the air inlet 21 of the valve body 20, the outside air is not introduced into the interior of the air temperature rise is prevented.

그러나, 도어가 개방되는 경우에는 개폐편(30)이 공기의 흐름에 따라 홈부(32)를 중심으로 내측으로 밀려 들어가 공기흡입구(21)를 개방하게 된다. 이로인해, 다량의 공기가 순간적으로 고내로 유입되어 고내·외의 압력차가 단시간내에 해소됨에 따라 도어는 원활하게 개방된다.However, when the door is opened, the opening and closing piece 30 is pushed inward with respect to the groove part 32 in accordance with the flow of air to open the air inlet 21. As a result, a large amount of air flows into the chamber at a moment and the pressure difference between the inside and the outside of the refrigerator is resolved within a short time, so that the door opens smoothly.

상기와 같이 고내로 공기가 유입된 후, 더 이상 공기의 유동이 없으면 개폐편(30)은 자체의 하중에 원위치로 복귀하게 된다. 따라서, 외부공기가 고내로 유입되어 고내온도를 상승시키거나 저온의 고내공기가 고외로 배출되는 것이 방지된다.After the air is introduced into the air as described above, when there is no more flow of air, the opening and closing piece 30 returns to its original position at its own load. Therefore, it is prevented that the outside air flows into the inside to raise the inside temperature or to discharge the inside of the low temperature high 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.
