본 고안은 전자렌지에 있어서, 캐비티 상측 천정 부위에 결합 설치되어 외부 공급용 바람에 의해 회전하면서 고주파를 고르게 분산시키는 스터러팬의 설치구조에 관한 것으로, 특히 축 고정 장치의 구조를 개선하여 스터러팬의 회전이 원활하게 이루어지도록 함에 주안점을 둔 것이다.The present invention relates to an installation structure of a stirrer fan, which is coupled to a ceiling upper ceiling part of a microwave oven and distributes high frequency evenly while being rotated by an external supply wind. The main focus is on smooth rotation.
종래의 스터러팬 설치구조를 보면 제4도에서와 같이, 상단이 볼트부(102')와, 외주연에 플렌지(101')가 형성된 합성수지 고정축(100')을 형상한뒤, 볼트부(102')로서 캐비티 천정판(8')을 관통시키고, 상측에서 너트(104')를 체결하여 고정시킨 다음, 그 하단부위에는 스터러팬(1') 중앙부위의 붓싱(2')을 끼욱고 록크와셔(103')로 이탈 방지형태로 지지 결합 설치하므로서, 스터러팬의 회전시 붓싱(2')이 고정축 하단부위를 중심으로 선회하도록 하였다.In the conventional stirrer pan installation structure, as shown in FIG. 4, the upper end forms the bolt portion 102 'and the synthetic resin fixing shaft 100' having the flange 101 'formed on the outer circumference thereof, and then the bolt portion ( 102 ') through the cavity ceiling plate 8' and fasten by fixing the nut 104 'from the upper side, and then insert the bushing 2' at the center of the stirrer pan 1 'at the lower end and lock it. The support was installed in the form of a separation prevention with the washer (103 '), so that the bushing (2') is rotated about the lower end of the fixed shaft during rotation of the stirrer pan.
그런데, 상기와 같은 종래의 구조는 플렌지(101')의 상측면과 캐비티 천정판(8') 사이의 접촉부 평탄도가 완벽하지 못하므로, 고정축(100')이 지면과 완벽한 수직 형태로 세워지지 않아 스터러팬이 편심 상태로 결합되면서 회전이 원활하지 못하다.However, in the conventional structure as described above, the flatness of the contact portion between the upper surface of the flange 101 'and the cavity ceiling plate 8' is not perfect, so that the fixed shaft 100 'is placed in a perfectly vertical shape with the ground. Since the stirrer fan is coupled in an eccentric state, the rotation is not smooth.
또한, 상측 나사부(102')에 너트(104')를 체결시 설정된 힘보다 약간의 힘이 더 가해져도 나사부의 마모나 목부위의 파손현상이 쉽게 발생하고, 스터러팬 붓싱의 내경과 고정축 하단 결합부와의 치수공차로 인하여 회전시 기울러지게 되며, 스터러팬 붓싱의 코킹 작업면이 매끄럽지 못할때는 하방측 로크와셔(103')와의 접촉 마찰이 크게 되어 스터러팬이 잘 회전하지 못하게 되는 문제점이 있었다.In addition, even if a slight force is applied to the upper threaded portion 102 'than the set force when tightening the nut 104', wear of the threaded portion or breakage of the neck part occurs easily, and the inner diameter of the stirrer pan bushing and the lower end of the fixed shaft Due to the dimensional tolerances with the coupling portion, when the rotation is inclined, when the caulking work surface of the stirrer fan bushing is not smooth, the contact friction with the lower lock washer (103 ') is large, the problem that the stirrer pan does not rotate well. there was.
따라서, 본 고안의 목적은 상기와 같은 종래의 문제점을 해결함과 동시, 스터러팬의 완벽한 결합과 원활한 작동이 이루어 지도록 하는 개선된 설치구조를 제공함에 있는 것이다.Accordingly, it is an object of the present invention to solve the conventional problems as described above, and to provide an improved installation structure to achieve a perfect coupling and smooth operation of the stirrer fan.
상기와 같은 목적을 달성하기 위하여, 상단에 플렌지를 구비한 원통형 슬리브를 캐비티 천정판에 고정 결합시킨뒤, 그 내부에 회전축을 결합시켜 놓고, 회전축의 하단에 돌기와 홈으로서 스터러팬 붓싱을 끼워 맞춤 결합시켜, 스터러팬과 회전축이 함께 선회동작 되도록 한 것인바, 이를 첨부된 예시도면에 의거 상세히 설명하면 다음과 같다.In order to achieve the above object, the cylindrical sleeve having a flange at the top is fixedly coupled to the cavity ceiling plate, and then the rotation shaft is coupled to the inside thereof, and the stirrer fan bushing is fitted as a protrusion and a groove at the bottom of the rotation shaft. By doing so, the stirrer fan and the rotating shaft is to be rotated together, which will be described in detail based on the accompanying drawings.
즉, 캐비티 내부의 천정판(8) 일측 부위에 스터러팬(1)과 축을 설치함에 있어서,도면 제1도에서와 같이 상단 외주연에 플레지(61)를 구비한 소정 길이의 원통형 슬리브(6)로서 천정판(8)을 관통시킨뒤, 플렌지를 천정판의 상측면상에 스크류로서 관통 체결 하였다.That is, in the installation of the stirrer pan 1 and the shaft on one side of the ceiling plate 8 inside the cavity, as shown in FIG. After passing through the ceiling plate 8, the flange was penetrated with a screw on the upper surface of the ceiling plate.
그리고, 하단부에 적어도 1개 이상의 걸림용 외향 돌출부(31)를 구비한 회전축(3)의 상단 부위를 상기 원통형 슬리브(6) 내부를 통해 상측으로 돌출시킨뒤, 슬라이드와셔(5)와 고정와셔(4)로서 공회전 자재토록 설치하였다.Then, the upper end portion of the rotary shaft 3 having at least one or more engaging outward protrusions 31 for engaging at the lower end protrudes upward through the cylindrical sleeve 6, and then the slide washer 5 and the fixed washer ( 4) as the idle material.
또한, 도면 제2도에서와 같이 스터러팬(1) 회전 중심 부위의 붓싱(2) 하단부위에는 상기 회전축의 외향 돌출부(31)와 끼워 맞춤 형태로 결합되는 요홈(21)을 형성하여, 붓싱(2)이 회전축(3)의 하단부위에 끼워진 상태에서 요홈(21)이 외향 돌출부(31)와 결합 되므로서, 붓싱과 회전축이 동시 선회되도록 설치한 것이다.In addition, as shown in FIG. 2, the lower end portion of the bushing 2 of the rotation center of the stirrer fan 1 is formed with a recess 21 that is engaged with the outward protrusion 31 of the rotation shaft in a fitting manner, and the bushing 2 Since the groove 21 is coupled with the outward protrusion 31 in a state where the bottom portion of the rotary shaft 3 is fitted, the bushing and the rotary shaft are pivoted at the same time.
이상과 같이 구성된 본 고안은, 캐비티 외측방에서 공급되는 바람이 스터러팬(1)과 접하여 발생되는 회전력이 붓싱(2)의 요홈(21)과 결합된 외향 돌출부(31)로 전달되므로서, 스터러팬(1)이 회전샤프트(3)와 동시 선회 되는 것이다.The present invention configured as described above, as the rotational force generated by the wind supplied from the outside of the cavity in contact with the stirrer fan (1) is transmitted to the outward protrusion (31) coupled with the groove (21) of the bushing (2), The lun pan 1 is pivoted simultaneously with the rotary shaft 3.
이때, 회전축(3)은 상단에 결합시킨 고정와셔(4)와, 플렌지(61) 사이에 위치하는 슬라이드와셔(5)에 의해 별 다른 마찰 없이 슬리브 (6)내에서 원활하게 선회 동작 한다.At this time, the rotating shaft 3 is smoothly swiveled in the sleeve 6 without any friction by the fixed washer 4 coupled to the upper end and the slide washer 5 located between the flange 61.
이상과 같이 구성되고 작동되는 본 고안은, 회전축(3)이 캐비티 천정판에 관통 체결 설치된 원통형 슬리브(6)내에 삽입되고 와셔로서 지지 설치되므로서, 종래의 나사부와 너트를 이용한 축 체결 고정설치 방식보다 간편하고 수월하게 그리고 정확하게 설치 함은 물론이고, 축 설치상의 불량률을 대폭 감소시킬 수 있을 뿐만 아니라, 스터러팬과 회전축의 동시 선회 형태로 구성하여 종래와 같은 스터러팬과 축과의 편심결합에 따른 회전동작의 불안전성과 작동중 소음을 완벽하게 방지할 수 있는 등의 특출한 효과가 있는 것이다.The present invention is constructed and operated as described above, the rotation shaft 3 is inserted into the cylindrical sleeve 6 through-fastened to the cavity ceiling plate and supported as a washer, so that the shaft fastening fixed installation method using a conventional screw part and nut Not only can it be installed more easily, easily and accurately, but it can also greatly reduce the defective rate of the shaft installation, and it is composed of the swivel fan and the rotating shaft at the same time. There is an extraordinary effect, such as the instability of rotational movements and the ability to completely prevent noise during operation.
