Description

공기정화기능을 갖는 전자렌지{A microwave-oven having air purification}Microwave with air purification function {A microwave-oven having air purification}

본 발명은 전자렌지에 관한 것으로, 상세하게는 전자렌지의 전장실을 경유한 공기가 외부로 배출되는 공기유동경로상에 이산화티타늄(TiO2)과 같은 광촉매 탈취재가 함유된 필터를 설치함으로써 조리과정에서 발생한 음식물의 냄새의 제거와 함께 전자렌지 주변의 악취를 제거할 수 있도록 구성한 것이다.The present invention relates to a microwave oven, and in particular, in the cooking process by installing a filter containing a photocatalyst deodorant such as titanium dioxide (TiO2) on the air flow path through which the air passing through the electric chamber of the microwave oven is discharged to the outside. It is configured to remove the smell of food and smells around the microwave oven.

일반적으로 열전도나 열복사에 의한 조리기구와 달리 초고주파를 음식물에 조사함으로써 음식물중에 함유된 물분자의 병진운동에 따른 유전가열로서 음식물을 조리하는 전자렌지는 마그네트론(magnetron)이라는 초고주파 발진관에 고압전기를 가함에 따라 발생하는 초고주파에 의해 음식물을 조리한다.In general, unlike microwave cooking utensils by heat conduction or heat radiation, microwaves are cooked as a dielectric heating according to the translational movement of water molecules contained in the food, and microwaves are prepared by applying high voltage electricity to an ultra-high frequency oscillator tube called magnetron. The food is cooked by the ultra-high frequency generated by the addition.

특히, 이와 같은 전자렌지는 음식물의 내부 및 외부를 동시에 가열함으로써 높은 열효율에 의해 음식물의 해동이나 조리시간을 대폭 단축하고, 음식물의 조리나 해동 및 데우기 과정에서 영양가의 손실을 줄일 수 있으며, 또한 음식물을 용기에 담은 채로 조리가 가능하다는 등의 장점으로 인해 널리 쓰이고 있다.In particular, the microwave oven heats the inside and the outside of the food at the same time, which greatly reduces the thawing or cooking time of the food by high thermal efficiency, and reduces the loss of nutritional value during the cooking, thawing and warming of the food. It is widely used due to its advantages such as cooking in a container.

상기한 바와 같은 전자렌지는 극초단파를 발생시키도록 한 마그네트론 및 고압트랜스를 비롯하여 전자렌지의 동작을 제어하는 회로 및 냉각팬 등이 결합된 전장실이 구비되며, 상기한 전장실의 측면으로는 조리를 요하는 음식물의 저장공간을 제공하는 한편, 극초단파의 확산에 따라 음식물에 대한 가열이 이루어지는 조리실이 구비된다.As described above, the microwave oven is equipped with a magnetron and a high voltage transformer for generating microwaves, a circuit for controlling the operation of the microwave, and an electric chamber combined with a cooling fan. While providing a storage space of the required food, there is provided a cooking chamber that is heated to the food according to the diffusion of microwaves.

이와 같은 구조를 갖는 전자렌지는 사용특성상 수분이 함유된 음식물이 조리되는 동시에, 음식물의 조리과정에서 용기로부터 음식물이 비산됨으로써 전자렌지의 조리실 내부는 세균의 증식에 유리한 환경을 제공한다.Microwave oven having such a structure, the food containing water is cooked at the same time, the food is splashed from the container during the cooking process of the food, the inside of the cooking chamber of the microwave provides an environment for the growth of bacteria.

따라서, 전자렌지의 조리실 내부에는 인체에 유해한 세균의 증식 가능성이 높은 관계로 최근에는 자외선램프를 설치함으로써 조리실에 서식하는 각종 세균을멸균시키는 한편, 이에 따라 음식물에 대한 위생적인 조리가 가능한 전자렌지가 사용되고 있다.Therefore, since there is a high possibility of the growth of germs harmful to the human body inside the cooking chamber of the microwave, by installing an ultraviolet lamp in recent years, it is possible to sterilize various bacteria living in the cooking chamber, and accordingly, a microwave oven capable of hygienic cooking of food It is used.

도 1은 상기한 바와 같이 조리실(450) 천정판(310) 상부에 자외선램프(L)를 설치한 전자렌지(400)의 일례를 도시한 도면으로, 이와 같이 조리실(450)의 살균을 위해 자외선램프(L)를 구비한 종래의 전자렌지(400)는 조리실(450)의 천정판(310)을 상부 방향으로 함몰시키고, 상기한 천정판(310) 상부의 공간 내측으로 자외선램프(L)를 결합시킨 구조로 이루어진다.1 is a view illustrating an example of a microwave oven 400 in which an ultraviolet lamp L is installed on the ceiling plate 310 of the cooking chamber 450 as described above, and thus, ultraviolet rays are used for sterilization of the cooking chamber 450. The conventional microwave oven 400 having the lamp L recesses the ceiling plate 310 of the cooking chamber 450 in the upper direction, and places the ultraviolet lamp L inside the space above the ceiling plate 310. It is made of a combined structure.

상기한 자외선램프(L)는 통상적인 형광램프용 홀더와 같이 전원의 공급을 위해 자외선램프(L)의 전극과 접속하는 접점을 내부에 구비한 홀더(350)에 의해 양단이 각각 지지된 상태로 천정판(310)의 상부로부터 수평으로 장착된다.The ultraviolet lamp L has a state in which both ends thereof are supported by holders 350 having contacts therein for connecting the electrodes of the ultraviolet lamp L to supply power, such as a holder for a conventional fluorescent lamp. It is mounted horizontally from the top of the ceiling plate 310.

이와 같이 결합된 자외선램프(L)는 음식물의 조리전후에 일정시간 점등됨에 따라 특정 파장에 의해 멸균특성을 갖는 자외선이 조리실(450)로 조사됨으로써 내부의 유해한 세균을 멸균시킨다.The UV lamp (L) coupled as described above is illuminated for a certain time before and after cooking of food to sterilize harmful bacteria therein by irradiating ultraviolet light having a sterilization property to the cooking chamber 450 by a specific wavelength.

한편, 상기한 바와 같이 자외선램프(L)의 따라 조사된 자외선은 조리실(450) 내부를 멸균시킴으로써 위생적인 조리가 가능하도록 하는 반면, 조리과정에서 발생한 음식물의 냄새에 대한 소취효과가 없어 조리실(450) 내부에 음식물 냄새가 잔류하며, 특히 자외선램프(L)가 없는 기존의 전자렌지는 세균의 증식과 함께 조리실 내부로부터 악취가 발생하므로 전자렌지의 사용과정에서 소비자에게 많은 불쾌감을 준다.Meanwhile, as described above, the ultraviolet rays irradiated along the ultraviolet lamp L enable sanitary cooking by sterilizing the inside of the cooking chamber 450, while there is no deodorizing effect on the smell of food generated during the cooking process. ) The smell of food remains inside, and in particular, existing microwave ovens without UV lamps (L) generate a lot of unpleasant feelings to consumers during the use of microwave ovens because of the growth of bacteria and odor generated from the inside of the cooking chamber.

본 발명은 상기한 바와 같은 종래의 문제점을 해결하기 위한 것으로, 본 발명의 기술적 과제는, 전자렌지의 전장실을 경유한 공기가 외부로 배출되는 공기유동경로상에 이산화티타늄과 같은 광촉매 탈취재가 함유된 필터를 설치함으로써 조리과정에서 발생한 음식물의 냄새나 전자렌지 주변의 악취를 제거할 수 있는 수단을 제공하는 것이다.The present invention is to solve the conventional problems as described above, the technical problem of the present invention, a photocatalyst deodorant such as titanium dioxide is contained on the air flow path through which the air passing through the electric chamber of the microwave oven is discharged to the outside. It is to provide a means for removing the smell of food or odors around the microwave oven by installing the prepared filter.

상기한 바와 같은 본 발명의 기술적 과제는, 전자렌지의 조리실 상부에 자외선 램프를 구비하고, 흡기공을 통해 외부로부터 유입된 공기가 전장실을 경유하여 공기배출공으로 배출되도록 한 전자렌지에 있어서,Technical problem of the present invention as described above, in the microwave oven provided with an ultraviolet lamp in the upper part of the cooking chamber of the microwave oven, the air introduced from the outside through the intake hole is discharged to the air discharge hole via the electrical equipment room,

상기 흡기공 및 공기배출공 사이에 공기의 흐름을 유도하도록 내측에 자외선램프 설치공을 갖는 덕트를 설치하고, 상기 덕트의 선단 양측에 형성한 수직 절곡부의 내측으로는 자외선에 의해 냄새를 분해시키도록 이산화티타늄을 함유한 광촉매필터를 부착시켜 송풍팬의 동작에 따라 외부로 배출되는 공기가 상기한 광촉매필터를 경유하도록 구성한 것을 특징으로 하는 공기정화기능을 갖는 전자렌지를 제공함으로써 달성된다.A duct having an ultraviolet lamp installation hole is installed inside to induce the flow of air between the intake hole and the air discharge hole, and inside the vertical bent portion formed at both ends of the duct to decompose odor by ultraviolet light. It is achieved by attaching a photocatalyst filter containing titanium dioxide so that the air discharged to the outside according to the operation of the blowing fan is configured to pass through the photocatalyst filter.
