본 발명은 냉장고 캐비넷의 이슬맺힘 방지구조에 관한 것으로, 특히, 냉장고의 냉동실과 냉장실의 온도 대역이 다름에 따라 외부 온도와 습도에 대한 이슬 맺힘 조건이 상이하여 냉동실과 냉장실에 대응된 캐비넷부위의 이슬 맺힘을 방지하기 위한 구조 개선에 관한 것이다.The present invention relates to a structure for preventing dew condensation of a refrigerator cabinet, and in particular, dew condensation of a cabinet part corresponding to a freezer compartment and a refrigerator compartment due to different dew condensation conditions for external temperature and humidity according to a different temperature range of a freezer compartment and a refrigerator compartment of a refrigerator. It relates to a structural improvement to prevent condensation.

일반적으로, 냉장고에서는 냉장실과 냉동실 내의 온도와 습도와 냉장고 외부의 온도와 습도 보다 낮음에 따라 상대적으로 습도가 높은 냉장고 외부의 대기중에 함유된 습기가 냉장고 캐비넷 표면에 응결되어 이슬맺힘 현상이 발생된다.In general, in the refrigerator, as the temperature and humidity of the refrigerator compartment and the freezer are lower than the temperature and humidity of the outside of the refrigerator, moisture contained in the atmosphere outside the refrigerator having a relatively high humidity condenses on the surface of the refrigerator cabinet, thereby causing dew formation.

이러한 냉장고 캐비넷 표면에서의 이슬 맺힘을 방지하기 위하여, 종래에는 도 1에 도시된 바와같이 냉장고 캐비넷(1)과 내상 사이에 소위 핫파이프라고 하는, 압축기에서 토출된 고온의 냉매 유로용 파이프(2)를 배치하여 그 열에 의해 냉장고 캐비넷을 가열함으로써 그 표면에서의 이슬 맺힘을 방지하도록 하였다.In order to prevent dew condensation on the surface of such a refrigerator cabinet, as shown in FIG. 1, a pipe for a high temperature refrigerant flow path 2 discharged from a compressor, called a hot pipe, between the refrigerator cabinet 1 and the inner phase. Was arranged to heat the refrigerator cabinet by the heat to prevent dew condensation on its surface.

그러나, 이러한 방식의 냉장고 이슬맺힘 방지구조는 냉동실과 냉장실내의 온도가 외기 온도와의 편차 및 상대 습도의 차이등에 관계없이 압축기의 구동을 필요로 하기 때문에 전력 소모가 많은 문제점이 있었다.However, this type of refrigerator dew preventing structure has a problem in that power consumption is high because the temperature in the freezer compartment and the refrigerating compartment requires the operation of the compressor irrespective of the deviation from the outside temperature and the difference in relative humidity.

따라서, 본 발명의 목적은 종래 압축기를 구동하여 고온의 냉매를 냉동실과 냉장실 주변의 냉장고 캐비넷 내측에 파이프를 통하여 유동하게 함으로써 냉장고 캐비넷의 이슬 맺힘을 방지하는 구조에 대한 과도한 전력 소모의 문제점을 해결하기 위하여 냉장실과 냉동실내부와 외기의 온도 편차 및 상대 습도의 편차에 따라 냉동실 주변과 냉장실 주변에 별도의 히터를 매설하여 대응된 캐비넷 부위에서의 이슬맺힘을 효율적으로 방지하도록 개선된 구조를 제공하는 것이다.Accordingly, an object of the present invention is to solve the problem of excessive power consumption for the structure that prevents dew condensation of the refrigerator cabinet by driving a conventional compressor to allow the high temperature refrigerant to flow through the pipe inside the refrigerator cabinet around the freezer compartment and the refrigerator compartment. In order to provide an improved structure to effectively prevent dew condensation in the corresponding cabinet part by embedding a separate heater around the freezer compartment and the refrigerating compartment in accordance with the deviation of the temperature and relative humidity of the inside of the refrigerator compartment and the freezer compartment.

상기한 목적을 달성하기 위한 본 발명의 형태에 따르면 냉장고의 캐비넷 이슬맺힘 방지구조는 냉장고의 냉동실과 냉장실에 인접한 캐비넷 내측에 히터를 배치하여 캐비넷을 가열하여 캐비넷 표면에서의 이슬 맺힘을 방지하도록 된 냉장고 캐비넷 이슬맺힘 방지구조에 있어서, 상기 히터는 냉동실 코드히터 및 냉장실 코드히터로서 냉동실과 냉장실 각각의 대응된 전면부의 내측에 배치되며, 상기 냉동실 코드히터 및 냉장실 코드히터는 각각 온도 및 습도센서에 의해 감지된 냉장고의 외부의 온도와 상대습도 조건에 따라 마이콤에 의해 개별적으로 제어되는 것을 특징으로 하여 구성된다.According to an aspect of the present invention for achieving the above object is a cabinet dew preventing structure of the refrigerator is arranged to place a heater inside the cabinet adjacent to the freezer compartment and the refrigerating compartment of the refrigerator to heat the cabinet to prevent dew condensation on the cabinet surface In the cabinet dew preventing structure, the heater is a freezer compartment code heater and a refrigerating compartment code heater, which is disposed inside a corresponding front portion of each of the freezer compartment and the refrigerating compartment, and the freezer compartment cord heater and the refrigerating compartment code heater are respectively sensed by a temperature and humidity sensor. It is configured to be individually controlled by the microcomputer according to the temperature and relative humidity conditions of the external refrigerator.

상기 마이콤은 냉장고 외부, 즉 실내 온도가 35℃이상인 경우에 냉동실 및 냉장실 주변의 캐비넷 내측에 배치된 냉동실 코드히터 및 냉장실 코드히터를 외부의 상대습도에 비례한 운전율로 구동하며, 실내 온도가 30℃ 이상 ~ 35℃ 미만인 경우에는 냉동실 코드히터 및 냉장실 코드히터를 구동시키되 운전율을 실내의 상대습도의 70% ±10%에 비례하게 구동시키고, 실내 온도가 25℃ 이상 ~ 30℃ 미만인 경우에는 냉동실 코드히터만을 구동시키고 냉장실 코드히터는 구동하지 않고, 상기 냉동실 코드히터는 외부의 상대 습도에 대하여 50% ±10%에 비례하게 구동되도록 제어하도록 구성되는 것이 바람직하다.The microcomputer drives the freezer compartment cord heater and the refrigerator compartment cord heater disposed at the outside of the refrigerator, that is, inside the cabinet around the freezer compartment and the refrigerator compartment at an operating temperature proportional to the external relative humidity when the room temperature is 35 ° C. or higher. If the temperature is higher than or equal to ~ 35 ℃, the freezer compartment code heater and the refrigerating compartment code heater are driven, but the operation rate is driven in proportion to 70% ± 10% of the relative humidity of the room, and the freezer compartment when the room temperature is 25 ° C or more and less than 30 ° C. Preferably, only the code heater is driven and the refrigerating chamber code heater is not driven, and the freezer compartment code heater is configured to be controlled to be proportional to 50% ± 10% relative to external relative humidity.

이하, 본 발명의 실시예를 도시한 첨부 도면을 참고하여 본 발명을 상세히 설명 하기로 한다.Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in detail the present invention.

도 2에 개략적으로 도시된 바와같이, 본 발명에 의한 냉장고 캐비넷 이슬맺힘 방지구조는 냉장고(10)의 냉동실(11)과 냉장실(12)에 인접한 캐비넷(13)의 대응된 전면부의 내측에 냉동실 코드히터(15)와 냉장실 코드히터(16)를 각각 배치하고, 통상의 냉장고 제조방법에서와 같이 캐비넷과 내상 사이에 우레탄 발포액을 주입하여 발포시킨다. As schematically shown in FIG. 2, the refrigerator cabinet dew preventing structure according to the present invention has a freezer compartment cord inside a corresponding front portion of a cabinet 13 adjacent to the freezer compartment 11 and the refrigerating compartment 12 of the refrigerator 10. The heater 15 and the refrigerating chamber cord heater 16 are arranged respectively, and the urethane foaming liquid is injected and foamed between a cabinet and an inner phase like a normal refrigerator manufacturing method.

상기 코드히터(15,16)들은 각각 릴레이(17,18)를 통하여 마이콤(20)에 의해 제어되며, 상기 마이콤은 냉장고의 외부, 즉 냉장고가 설치된 실내 온도와 상대습도를 감지하기 위한 온도 및 습도 센서(19)들로부터 출력신호를 받아 도 3에 도시된 제어 흐름도와 같이 냉동실 주위의 캐비넷부위와 냉장실 주위의 캐비넷 부위를 해당 코드히터(15,16)들로 각각 독립적으로 제어하게 된다.The code heaters 15 and 16 are controlled by the microcomputer 20 through the relays 17 and 18, respectively, and the microcom is external to the refrigerator, that is, a temperature and humidity for sensing an indoor temperature and a relative humidity at which the refrigerator is installed. Receiving an output signal from the sensors 19, as shown in the control flow chart shown in Figure 3 to control the cabinet portion around the freezer compartment and the cabinet portion around the refrigerating compartment independently with the corresponding code heaters (15, 16).

도 3에는 마이콤에 의한 냉동실 및 냉장실 주위의 캐비넷에서의 이슬 맺힘을 방지하기 위하여 해당 캐비넷부위에 인접하여 배치된 코드히터들을 개별적으로 제어하기 위한 흐름도가 도시되어 있으며, 도 3을 참고하여 본 발명에 의한 냉장고 캐비넷 이슬 맺힘 방지 작용을 설명하기로 한다.3 is a flow chart for individually controlling the code heaters disposed adjacent to the cabinet part in order to prevent dew condensation in the cabinet around the freezer compartment and the refrigerating compartment by the microcomputer, and according to the present invention with reference to FIG. The effect of preventing dew condensation in the refrigerator cabinet will be described.

냉장고 외부, 즉 실내 온도가 35℃이상인 경우에는 냉동실 및 냉장실 주변의 캐비넷 내측에 배치된 코드히터(15,16)들 모두를 구동하며, 이때 히터들의 운전율은 냉장고 외부의 실내 상대습도에 비례한다.When the outside of the refrigerator, that is, the room temperature is 35 ° C. or higher, drives all of the cord heaters 15 and 16 disposed inside the cabinet around the freezer compartment and the refrigerator compartment, and the operation rate of the heaters is proportional to the indoor relative humidity outside the refrigerator. .

실내 온도가 30℃ 이상 ~ 35℃ 미만인 경우에는 코드히터(15,16)를 모두 구동시키되, 운전율을 실내의 상대습도의 70%에 비례하게 구동시킨다.When the room temperature is 30 ° C. or higher and less than 35 ° C., all the code heaters 15 and 16 are driven, but the driving rate is proportional to 70% of the relative humidity of the room.

또한, 실내 온도가 25℃ 이상 ~ 30℃ 미만인 경우에는 냉동실 주변의 캐비넷 이슬 맺힘을 방지하기 위한 냉동실 코드히터(15)만을 구동시키고 냉장실 주변에 배치된 냉장실 코드히터(16)는 구동하지 않는 상태로서, 냉동실 코드히터(15)는 외부 상대 습도에 대하여 50%에 비례하게 구동된다.In addition, when the room temperature is 25 ° C. or more and less than 30 ° C., only the freezer compartment cord heater 15 for preventing the formation of cabinet dew around the freezer compartment and the refrigerator compartment cord heater 16 disposed around the refrigerator compartment are not driven. , Freezer compartment code heater 15 is driven in proportion to 50% relative to the external relative humidity.

실내 온도가 25℃ 미만에서는 코드 히터(15,16)들을 모두 정지시킨다. 위에서 상대습도는 ±10%의 범위내에서 설정하는 것이 바람직하다.If the room temperature is below 25 ° C, the cord heaters 15 and 16 are both stopped. In the above, the relative humidity is preferably set within the range of ± 10%.

본 발명에 따라, 코드히터들을 냉장고의 냉동실과 냉장실 주변의 캐비넷 내측에 개별적으로 설치하여 냉동실과 냉장실 주변의 캐비넷 부위를 각각 냉장고 외부, 즉 실내 온도와 습도에 따라 독립적으로 히터를 제어함으로써, 외부의 온도와 습도 조건의 변화에 관계없이 항상 냉장고 캐비넷에서의 이슬 맺힘의 방지가 보장되므로 상품가치가 향상된다.According to the present invention, the code heaters are separately installed inside the cabinets around the freezer compartment and the refrigerating compartment of the refrigerator to control the heaters independently of the refrigerator compartment and the refrigerator compartment according to the room temperature and humidity, respectively. Regardless of temperature and humidity conditions, dew condensation in the refrigerator cabinet is always assured, increasing the value of goods.

또한, 종래 냉장고 캐비넷 표면에서의 이슬 맺힘을 방지하기 위하여 압축기를 구동하여 고온의 냉매를 냉동실과 냉장실 주변의 캐비넷 내측에 배치된 파이프를 통해 유동시키는 것과 비교하여 압축기 구동 전력 소모가 많고 외부의 온도와 습도 조건에 따라 냉장고의 냉동실과 냉장실 주변의 캐비넷 표면에서의 이슬 맺힘 조건의 차이에 적합하게 조절할 수 없는 문제점이 해결되어, 코드 히터를 냉동실과 냉장실 주변의 캐비넷 내측에 배치하여 외부의 온도와 습도 조건에 따라 독립적으로 구동시켜 이슬맺힘을 주변 조건에 따라 정확하게 방지할 수 있고, 전력 소모를 최소호하는 장점이 있다.In addition, in order to prevent dew condensation on the surface of a conventional refrigerator cabinet, the compressor driving power consumption is high compared to flowing a high-temperature refrigerant through a pipe disposed inside the cabinet around the freezer compartment and the refrigerating compartment. According to the humidity conditions, the problem that cannot be adjusted appropriately to the difference of dew condensation on the cabinet surface around the freezer compartment and the refrigerating compartment of the refrigerator is solved. By independently driving, dew condensation can be prevented accurately according to the surrounding conditions, and there is an advantage of minimizing power consumption.
