냉장고의 제상히터 보호장치Defrost heater protection device of refrigerator

본 발명은 냉장고의 제상히터 보호장치에 관한 것으로, 보다 상세하게는 증발기의 양측 하단부의 일측면에 홈을 형성시켜 상기 홈에 제상장치의 상부커버를 끼움고정시켜 증발기에서 낙수되는 제상수로부터 제상히터를 보호하는 냉장고의 제상히터 보호장치에 관한 것이다.The present invention relates to a defrost heater protection device of the refrigerator, and more particularly, to form a groove on one side of the lower end of both sides of the evaporator to fit the upper cover of the defrosting device to the groove defrost heater from the dewatering water falling in the evaporator It relates to a defrost heater protection device of the refrigerator to protect the.

일반적으로 냉장고는 음식물을 일정기간 동안 신선하게 유지시켜주는 용도로 사용되는 전자제품으로 본체, 본체 내부에 양분되어 음식물을 냉동 보관하는 냉동실 및 냉장 보관하는 냉장실, 본체의 전면에 설치되어 냉동실을 개폐시켜 주는 냉동실도어 및 냉장실을 개폐시켜 주는 냉장실도어, 상기 냉동실과 냉장실의 냉각에 필요한 냉기를 만들어 주도록 냉동싸이클이 실행되는 냉각장치, 냉동싸이클의 실행도중 발생되는 냉기를 냉동실 및 냉장실로 보내주는 냉기공급수단, 상기 냉동싸이클이 실행되는 냉각장치중 증발기 상에 생성되는 성에 제거하는 제상히터로 크게 구성된다.In general, a refrigerator is an electronic product used to keep food fresh for a certain period of time. A refrigerator is a main body, a freezer compartment for freezing food and frozen food, and a cold compartment for food storage. The main compartment is a refrigerator compartment door that opens and closes the freezer door and the refrigerating compartment, a cooling device in which a freezing cycle is executed to create cold air for cooling the freezer compartment and a refrigerating compartment, and a cold air supply means for sending cold air generated during the execution of the freezing cycle to the freezer compartment and the refrigerating compartment. It is composed of a defrost heater that removes the frost generated on the evaporator of the cooling device in which the refrigeration cycle is executed.

상기 제상히터는 냉장고에 채용되는 부품으로서 냉매가 일련의 냉각싸이클을 따라 냉기를 생성하고 생성된 냉기가 냉동실 혹은 냉장실로 공급되고 난 후 해당 고내를 냉각시키는 일련의 열교환과정을 통하여 온도상승되며 이렇게 온도상승되어 온기로 바뀐 냉기는 리턴되어 다시 증발기가 위치한 냉각기실로 귀환되는 순환을 반복하게 되는 바, 이러한 과정에서 생성되는 냉기와 리턴되는 온기의 온도차이에 의해 서리(이슬)가 발생되게 되고 이들 서리(이슬)가 점차 증발기 표면에 착상되어 빙결되면서 성에를 생성하게 되는 데 이와 같은 성에를 주기적으로 체크하여 제거해 주는 전기적인 장치이다.The defrost heater is a component employed in a refrigerator, the refrigerant generates cold air along a series of cooling cycles, and the temperature rises through a series of heat exchange processes that cool the inside of the refrigerator after the generated cold air is supplied to the freezing compartment or the refrigerating compartment. The cold air that has been raised to warmer temperature is returned and returned to the cooler chamber where the evaporator is located. The frost (dew) is generated by the temperature difference between the cold air and the returned warmer. Dew) gradually forms on the surface of the evaporator and freezes to generate frost. It is an electrical device that periodically checks and removes such frost.

상기 제상히터는 통상 도 1에 나타낸 바와 같이, 냉동실과 냉장실을 적절하게 구획하는 부분(이하 "사절부"라함)의 후방측에 마련되며 그 바닥면이 양측단에서 중앙부를 향하여 다소 경사지게 형성되고 중앙부에는 배수구(12)가 마련되며 상기 바닥면의 양측에 서로 대응되는 형상과 크기로 돌설형성된 링형상의 지지대(14)를 갖는 제상수받이(10)와, 상기 제상수받이(10) 바닥면에 부착되는 코팅재(20)와, 상기 지지대(14) 사이에 위치되며 제상히터(40)를 하측에서 지지하는 하부커버(30)와, 상기 하부커버(30)에 고정되며 상기 제상히터(40)를 증발기(60)로부터 낙수되는 제상수로부터 보호하는 상부커버(50)로 구성된다.As shown in FIG. 1, the defrost heater is generally provided at the rear side of a portion that properly partitions the freezer compartment and the refrigerating compartment (hereinafter referred to as a "cutting section"), and its bottom surface is formed to be somewhat inclined toward the center portion at both ends thereof, and the center portion thereof.
