차량용 프리히터{PRE-HEATER FOR VEHICLE}Preheater for Vehicles {PRE-HEATER FOR VEHICLE}

본 발명은 차량용 프리히터에 관한 것으로써, 더욱 상세하게는 하우징을 일체형 박스형태로 구성하되 개구된 폭방향 일단부는 탄성부재를 구비한 커버로 슬라이딩 결합함으로써, 하우징의 강도 및 결합력을 향상함은 물론 결합구조가 간단하고 조립도 간편함과 아울러 커버에 탄성부재를 인서트 사출함에 따라 조립공수를 더욱 줄이고 부품 관리비용도 줄일 수 있는 차량용 프리히터에 관한 것이다.The present invention relates to a vehicle preheater, and more particularly, the housing is configured in the form of an integrated box, but one end of the widthwise opening is slid into a cover having an elastic member, thereby improving strength and coupling force of the housing. The present invention relates to a preheater for a vehicle in which the coupling structure is simple and the assembly is easy, as well as the injection molding of the elastic member to the cover further reduces the labor for assembling and reduces the parts management cost.

일반적으로 차량에는, 차실내의 난방이나 차량 전면유리의 제습 또는 성에제거를 위해 엔진에서 발생하는 열에 의해 데워진 냉각수의 열에너지를 이용하는 난방장치가 설치되어 있다.In general, a vehicle is provided with a heating device that uses the heat energy of the cooling water warmed by the heat generated by the engine for heating the interior of the vehicle or dehumidifying or defrosting the windshield of the vehicle.

이러한 난방장치는 엔진이 가동된 후 엔진의 주위를 흐르는 냉각수가 난방기에 유입되는 관계로 냉각수가 일단 가열되어 실내가 난방되기 까지는 장시간이 소요될 수 밖에 없다. 이에 따라, 시동 후 일정시간 추운 상태로 있어야 하는 단점이 있었다.Such a heating device has a long time until the cooling water is heated and the room is heated since the cooling water flowing around the engine is introduced into the heater after the engine is operated. Accordingly, there was a disadvantage in that the cold state for a certain time after starting.

근래, 이와 같은 문제를 해결하기 위한 프리히터가 다양하게 개발되고 있으며, 그 대표적인 것으로 PTC소자를 내장한 프리히터를 들 수 있다.Recently, various types of preheaters have been developed to solve such problems, and a typical example is a preheater incorporating a PTC element.

또한, 최근에는 플라스틱 재질의 상부하우징과 하부하우징을 상,하방향으로 결합하고, 그 사이에 PTC소자를 내장하는 프리히터가 개발되고 있다.In recent years, a preheater has been developed in which an upper housing and a lower housing of a plastic material are coupled in up and down directions, and a PTC device is embedded therebetween.

이러한 프리히터(1)의 일예로 국내 특허등록번호 제706856호가 개시되어 있으며, 도 1을 참조하여 간략히 설명하면, 상부하우징(10)의 가장자리 하측면에는 복수개의 결합리브(11)가 돌출 형성되고, 하부하우징(20)의 가장자리 상측면에는 상기 결합리브(11)가 삽입 결합되도록 복수개의 인입구멍(21)이 형성된다. 따라서, 상부하우징(10)과 하부하우징(20)을 상,하방향으로 결합하게 되는 것이다.An example of such a preheater 1 is disclosed in Korean Patent Registration No. 706856. Briefly described with reference to FIG. 1, a plurality of coupling ribs 11 protrude from the edge lower surface of the upper housing 10. On the upper side of the edge of the lower housing 20, a plurality of inlet holes 21 are formed to insert the coupling ribs 11. Therefore, the upper housing 10 and the lower housing 20 will be coupled in the up and down directions.

또한, 하부하우징(20)의 내측공간에는 가열수단(30)이 수용되고, 가열수단(30)의 일측에는 스프링요소(40)가 배치된다.In addition, the heating means 30 is accommodated in the inner space of the lower housing 20, the spring element 40 is disposed on one side of the heating means (30).

그리고, 상기 상부하우징(10)의 양측 결합리브(11) 중 일측 결합리브(11) 내측면에는 내측방향으로 경사진 경사면(11a)이 형성되어, 상,하부하우징(10,20)의 상,하방향 결합시 상기 경사면(11a)에 의해 스프링요소(40)가 가열수단(30)을 탄력적으로 압박하게 된다.In addition, an inclined surface 11a inclined inward is formed on an inner side of one coupling rib 11 of both coupling ribs 11 of the upper housing 10, and the upper and lower housings 10 and 20 are respectively The spring element 40 is elastically pressing the heating means 30 by the inclined surface (11a) when coupled downward.

한편, 상기 가열수단(30)은 +단자, -단자, PTC소자, 히트핀조립체 등이 적층되어 구성되며, 적층 구조나 형태는 공지된 것이므로 상세한 설명은 생략한다.On the other hand, the heating means 30 is configured by stacking the + terminal, the-terminal, the PTC element, the heat fin assembly, and the like, and a detailed description thereof is omitted since the stacking structure or form is well known.

이러한 상기 종래의 프리히터(1)는 하부하우징(20)의 내측공간에 먼저 가열수단(30)과 스프링요소(40)를 배치한 후, 상,하부하우징(10,20)을 상,하방향으로 결합하게 된다. 이후, 상기 +단자와 -단자에 전류가 공급되면 PTC소자에서 열이 발생하게 되고, 이 열이 히트핀조립체로 전열되므로 히트핀조립체를 통과하는 공기를 가열하게 되는 것이다.In the conventional preheater 1, the heating means 30 and the spring element 40 are first disposed in the inner space of the lower housing 20, and then the upper and lower housings 10 and 20 are moved up and down. Will be combined. Then, when the current is supplied to the + terminal and the-terminal, heat is generated in the PTC device, and the heat is transferred to the heat fin assembly, thereby heating the air passing through the heat fin assembly.

그러나, 상기 종래의 프리히터(1)는 상부하우징(10)과 하부하우징(20)을 상,하방향으로 결합하기 위해 복수개의 결합리브(11)와 복수개의 인입구멍(21)을 형성해야 하므로 결합구조가 복잡함과 아울러 좌,우 비틀림에 취약하여 결합력이 저하되는 문제가 있다.However, since the conventional preheater 1 has to form a plurality of coupling ribs 11 and a plurality of inlet holes 21 to couple the upper housing 10 and the lower housing 20 in the up and down directions. In addition to the complexity of the coupling structure, there is a problem that the bonding strength is lowered due to the weakness of the left and right twist.

또한, 하부하우징(20)의 내측공간에 가열수단(30)과 스프링요소(40)를 각각 배치하여 정위치 시킨 후, 상부하우징(10)을 하부하우징(20)에 결합해야 하기 때문에 조립이 불편한 문제가 있었다.In addition, after placing the heating means 30 and the spring element 40 in the inner space of the lower housing 20, respectively, in place, the assembling is inconvenient because the upper housing 10 must be coupled to the lower housing 20. There was a problem.

아울러, 조립공장에서 스프링요소(40)와 같은 부품들을 별도로 관리해야 하므로 관리비용도 증가하는 문제가 있었다.In addition, there is a problem in that the management cost is also increased because separate parts such as spring element 40 to be managed separately in the assembly plant.

상기한 문제점을 해결하기 위한 본 발명의 목적은 하우징을 일체형 박스형태로 구성하되 개구된 폭방향 일단부는 탄성부재를 구비한 커버로 슬라이딩 결합함으로써, 하우징의 강도 및 결합력을 향상함은 물론 결합구조가 간단하고 조립도 간편함과 아울러 커버에 탄성부재를 인서트 사출함에 따라 조립공수를 더욱 줄이고 부품 관리비용도 줄일 수 있는 차량용 프리히터를 제공하는데 있다.An object of the present invention for solving the above problems is to configure the housing in the form of an integrated box, but one end of the width direction is opened by sliding coupling with a cover having an elastic member, thereby improving the strength and bonding strength of the housing as well as the coupling structure is Simple and easy to assemble, as well as insert injection of the elastic member to the cover to provide a pre-heater for the vehicle that can further reduce the assembly labor and parts management costs.
