* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 캐비티 상판 2 : 팬 샤프트1: cavity top plate 2: fan shaft

2a : 안내홈 4 : 팬 허브2a: Home 4: Fan Hub

6 : 안내핀6: guide pin

본 고안은 전자레인지의 스터러팬 회전운동 안내장치에 관한 것으로, 특히 팬샤프트에는 안내홈을 형성하고 스터러팬의 허브에는 안내홈에 삽입 유착되는 안내핀을 고정하여 스터러팬이 일정주기의 상하 왕복운동을 하면서 회전할 수 있게한 전자레인지의 스터러팬 회전운동 안내장치에 관한 것이다.The present invention relates to a guide device for rotating motion of a stirrer pan of a microwave oven, in particular, a guide groove is formed in the fan shaft, and the hub of the stirrer fan is fixed with a guide pin which is inserted into the guide groove. It relates to a stirrer pan rotary motion guide device of the microwave oven that can be rotated while.

일반적으로 사용되고 있는 종래의 전자레인지에 있어서는 제1도에 도시한 바와 같이 전자레인지의 캐비티 상판(1)에 고정설치되는 팬샤프트(2)에 부쉬(3)(3')가 내주면 상하단부에 고정된 팬 허브(4)를 유착하고 그 팬 허브(4)의 하단에는 스터러팬(5)을 고정하였다.In a conventional microwave oven generally used, as shown in FIG. 1, bushes 3 and 3 'are fixed to upper and lower ends of an inner circumferential surface of a fan shaft 2 fixed to a cavity upper plate 1 of a microwave oven. The fan hub 4 was bonded to each other, and the stirrer fan 5 was fixed to the lower end of the fan hub 4.

따라서 그 스터러팬(5)은 전자레인지의 내부에 설치된 송풍기(도시되지 않음)에서 공급되는 바람에 의하여 수평방향으로만 회전하게 되므로 마그네트론(도시되지 않음)에서 발진된 고주파를 교반시켜 주는 효과가 양호하지 못한 결점이 있었다.Therefore, the stirrer fan (5) is rotated only in the horizontal direction by the wind supplied from the blower (not shown) installed inside the microwave oven, the effect of stirring the high frequency generated from the magnetron (not shown) is good There was a flaw that could not be made.

본 고안은 이와 같은 결함을 해소하기 위하여 안출한 것으로 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve such a defect and will be described in detail by the accompanying drawings as follows.

제2도에 도시한 바와 같이, 전자레인지의 캐비티 상판(1)에 고정설치된 팬샤프트(2)에 팬 허브(4)가 유착되고 팬 허브(4)의 하단에는 스터러팬(5)이 고정된 것에 있어서, 팬샤프트(2)의 중심축(C)과 일정경사각(θ)을 이루는 평면과 접하는 팬샤프트(2)의 외주연에 안내홈(2a)을 형성하고 팬 허브(4)의 몸체에는 일단이 안내홈(2a)에 삽입 유착되는 안내핀(6)을 삽입 고정한 것이다.As shown in FIG. 2, a fan hub 4 is adhered to a fan shaft 2 fixed to a cavity top plate 1 of a microwave oven, and a stirrer fan 5 is fixed to a lower end of the fan hub 4. In this case, the guide groove (2a) is formed on the outer periphery of the fan shaft (2) in contact with the plane forming a constant inclination angle (θ) of the central shaft (C) of the fan shaft (2), and the body of the fan hub (4) One end of the guide groove (2a) is inserted into the guide pin 6 is fixed.

이와 같이 구성된 본 고안은 허브(4)에 고정된 안내핀(6) 팬샤프트(2)의 외주연에 일정 경사도로 형성된 안내홈(2a)에 유착되어 있으므로 허브(4)의 하단에 고정된 스터러팬(5)이 송풍기에서 공급되는 바람에 의하여 주기적으로 상하 왕복운동하면서 회전하여 마그네트론에서 발진되는 고주파를 교반하게 된다.The present invention configured as described above is adhered to the guide groove 2a formed at a predetermined inclination on the outer circumference of the guide pin 6 fixed to the hub 4, and thus the stirrer fixed to the bottom of the hub 4 The fan 5 is rotated while periodically reciprocating by the wind supplied from the blower to agitate the high frequency oscillated from the magnetron.

상기와 같은 본 고안은 스터러팬이 주기적으로 상하 왕복운동하면서 회전하여 고주파를 교반하게 되므로 그 교반 효율이 단지 수평회전에 의하여만 교반하는 종래장치에 비하여 월등히 향상되는 이점이 있다.The present invention as described above has the advantage that the stirrer fan rotates while periodically reciprocating up and down to agitate the high frequency, the stirring efficiency is significantly improved compared to the conventional apparatus that only stirs by horizontal rotation.
