본 고안은 전자레인지의 조리실구조체에 관한 것으로, 특히 조리실내벽에 다수의 돌기를 형성하여 전자파를 난반사시키는 전자레인지의 조리실구조체에 관한 것이다.The present invention relates to a cooking chamber structure of a microwave oven, and more particularly, to a cooking chamber structure of a microwave oven that diffusely reflects electromagnetic waves by forming a plurality of protrusions on the inner wall of the cooking chamber.
잘 알려진 바와 같이, 전자레인지는 고주파수의 전자파로 식품에 포함된 물분자를 진동시키는 과정에서 발생하는 마찰열에 의하여 식품을 가열조리하는 기기이다.As is well known, a microwave oven is a device for heating and cooking food by frictional heat generated in the process of vibrating water molecules contained in the food by high frequency electromagnetic waves.
제1도는 종래의 전자레인지의 조리실구조를 보인 개략단면도이다. 제1도에 도시한 바와 같이, 종래의 전자레인지에서는 본체(1)의 중앙에 전면이 개구된 조리실(2)이 마련되는데, 상기 조리실(2)은 통상적으로 그 벽면이 매끄러운 평면으로 이루어진 금속재질의 사각함체형상을 하고 있다. 이러한 구조를 가지는 조리실(2)에 고주파수의 전자파가 도입되면, 조리실(2)의 구조체인 금속벽에 반사되어 여러방향으로 부터 음식물에 조사된다. 이 때, 조리실(2) 내에는 입사파와 반사파가 간섭해서 전자파의 강도가 높은 부분과 낮은 부분의 반복으로 이루어진 "정재파"가 존재하는 환경이 된다. 이러한 정재파의 발생으로 인하여 조리실(2)내의 전자파의 강도에 부분적으로 치우침이 발생하기 때문에 식품이 균일하게 가열되지 못하는 문제점이 있었다.1 is a schematic cross-sectional view showing a cooking chamber structure of a conventional microwave oven. As shown in FIG. 1, in a conventional microwave oven, a cooking chamber 2 having a front surface opened in the center of the main body 1 is provided, and the cooking chamber 2 is generally made of a metal material having a flat smooth wall surface. It has a rectangular box shape. When a high frequency electromagnetic wave is introduced into the cooking chamber 2 having such a structure, it is reflected by the metal wall which is the structure of the cooking chamber 2 and irradiated with food from various directions. At this time, in the cooking chamber 2, an incident wave and a reflected wave interfere with each other, where an "standing wave" formed by repetition of a portion having a high electromagnetic wave intensity and a low portion exists. Due to the generation of these standing waves, partial bias occurs in the intensity of the electromagnetic waves in the cooking chamber 2, and thus there is a problem in that the food is not heated uniformly.
이러한 문제점을 완화하기 위하여 종래에는 조리중에 회전접시에 의해서 식품을 회전시키거나 또는 교반익에 의해서 전자파를 분산시키고 있지만, 교반익이나 회전접시에 직접 닿지않는 전자파는 굴곡이 없는 조리실벽에서 일정한 형태를 지닌 채로 반사되기 때문에 여전히 정재파가 존재하는 환경이 형성되고, 이에 따라 균일가열에는 일정한 한계가 있었다.In order to alleviate this problem, conventionally, the food is rotated by the rotating dish or the stirring blade is dispersed during cooking, but the electromagnetic wave which does not directly touch the stirring blade or the rotating dish has a certain shape in the cooking wall without bending. Because it is reflected, it has an environment in which standing waves still exist, and thus uniform heating has a certain limit.
본 고안은 전술한 문제점을 해결하기 위하여 안출된 것으로서, 조리실내벽에 입사되는 전자파의 난반사를 유도하므로써 전자파의 집중현상을 완화시킬 수 있도록 한 전자레인지의 조리실구조체를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a cooking chamber structure of a microwave oven that can reduce the concentration phenomenon of electromagnetic waves by inducing diffuse reflection of electromagnetic waves incident on the inner wall of the cooking chamber.
전술한 목적을 달성하기 위한 본 고안의 전자레인지의 조리실구조체는 조리실에 도입된 전자파에너지에 의하여 식품을 가열하는 전자레인지에 있어서, 상기 조리실을 한정하는 내벽의 일부 또는 전부에 걸쳐서 다수의 돌기체를 형성한 것을 특징으로 한다.The cooking chamber structure of the microwave oven of the present invention for achieving the above object is a microwave oven for heating food by the electromagnetic energy introduced into the cooking chamber, a plurality of protrusions over part or all of the inner wall defining the cooking chamber Characterized in that formed.
이하에는 첨부한 도면을 참조하여 본 고안의 양호한 실시예에 따른 구성을 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the configuration according to a preferred embodiment of the present invention.
제2도는 본 고안의 전자레인지의 조리실구조를 보인 개략단면도이다. 제2도에 도시한 바와 같이, 본 고안에 따른 전자레인지에서는 본체(1)의 중앙에 전면이 개구된 조리실(2')이 마련되는데, 상기 조리실(2')은 통상적으로 금속재질의 사각함체형상을 하고 있다. 상기 조리실(2')을 한정하는 벽의 일부 또는 전부에는 다수의 반구형태의 돌기들(11)이 형성되는데 이러한 돌기들(11)은 불규칙하게 배열되거나 또는 규칙적으로 배열될 수 있다. 조리실(2')의 우측에는 고주파수의 전자파를 발생하는 마그네트론(4), 마그네트론(4)을 구동하기 위한 전원공급부(5; 통상적으로 고압트랜스포머, 고압다이오드 및 고압콘덴서를 포함하는 반파배전압회로로 이루어진다) 및 마그네트론(4)을 비롯한 전자레인지의 전체적인 동작을 제어하는 제어부(6)가 장착되는 전장실(3)이 마련된다. 전장실(3) 내부의 조리실(2')의 우측외벽에는 마그네트론(4)에서 발생된 전자파를 조리실(2')로 안내하는 도파관(7)이 장착된다. 조리실(2')의 바닥에는 구동모터(10)에 축결합된 지지롤러(9)에 지지된 채로 그 위에 재치되는 식품을 회전시키는 회전접시(8)가 놓여진다.2 is a schematic cross-sectional view showing the cooking chamber structure of the microwave oven of the present invention. As shown in FIG. 2, in the microwave oven according to the present invention, a cooking chamber 2 ′ having a front surface opened in the center of the main body 1 is provided, and the cooking chamber 2 ′ is typically a metal rectangular enclosure. It is shaped. A part or all of the walls defining the cooking chamber 2 'is formed with a plurality of hemispherical protrusions 11, which may be arranged irregularly or regularly. On the right side of the cooking chamber 2 ', a magnetron 4 generating high frequency electromagnetic waves, a power supply unit 5 for driving the magnetron 4; And the control unit 6 for controlling the overall operation of the microwave oven, including the magnetron 4, is provided. On the right outer wall of the cooking chamber 2 'inside the electric compartment 3, a waveguide 7 for guiding the electromagnetic waves generated from the magnetron 4 to the cooking chamber 2' is mounted. At the bottom of the cooking chamber 2 ′ is placed a rotary plate 8 for rotating the food placed thereon while being supported by the support roller 9 axially coupled to the drive motor 10.
전술한 구조를 가지는 본고안의 전자레인지의 조리실(2')에 전자파가 도입되게 되면, 그 입사각도의 미세한 차이에 따라 화살표에 도시된 바와 같이 반사각도는 큰 차이가 나기 때문에 전자파가 편중되는 현상이 상당수준 완화될 수가 있다. 특히, 회전접시(8; 또는 고주파 분산수단인 교반익)의 영향이 미치지 않는 벽면에서 난반사가 이루어지기 때문에 조리물의 높낮이별 분포편차를 개선하여 궁극적으로 음식물의 부위별 조리상태를 균일하게 유지시킬 수가 있다.When the electromagnetic wave is introduced into the cooking chamber 2 'of the microwave oven having the above-described structure, the reflection angle is greatly different as shown by the arrow according to the minute difference in the incident angle, so that the phenomenon of the electromagnetic wave is biased. It can be mitigated considerably. In particular, since diffuse reflection is performed on the wall surface which is not influenced by the rotating plate (or stirring blade, which is a high frequency dispersing means), it is possible to improve the distribution deviation according to the height of the food and ultimately to maintain the cooking state for each part of the food uniformly. have.
전술한 구성에서는 조리실(2')내에 반구형태의 돌기들(11)이 형성된 구조체를 개시하였지만, 이에 국한되는 것은 아니고 난반사를 효과적으로 유도할 수 있는 것이면 그 형상에는 제한이 없다.In the above-described configuration, the structure in which the hemispherical protrusions 11 are formed in the cooking chamber 2 'is disclosed, but the shape is not limited so long as it can effectively induce diffused reflection.
이상에서 설명한 바와 같은 본 고안의 전자레인지의 조리실구조체에 따르면, 조리실의 내벽에 다수의 돌기를 형성하여 입사되는 전자파의 난반사를 유도하므로써 균일조리, 특히 식품의 높낮이에 관계없이 균일조리가 수행되는 효과가 있다.According to the cooking chamber structure of the microwave oven according to the present invention as described above, uniform cooking is performed by inducing diffuse reflection of incident electromagnetic waves by forming a plurality of protrusions on the inner wall of the cooking chamber, especially regardless of the height of food. There is.
