본 발명은 증기조리장치 및 그 조리실 청소 방법에 관한 것으로, 더욱 상세하게는 청소시에 조리실에 증기를 공급하여 조리실 내부의 음식물 찌꺼기가 청소하기에 용이한 상태로 바뀌도록 하는 증기조리장치 및 그 조리실 청소 방법에 관한 것이다.The present invention relates to a steam cooking apparatus and a method for cleaning the cooking chamber, and more particularly, to a steam cooking apparatus for supplying steam to the cooking chamber at the time of cleaning so that the food waste inside the cooking chamber is changed to an easy state for cleaning and the cooking chamber. It is about a cleaning method.

일반적으로 음식물을 조리하는 통상적인 방법으로는 음식물을 가스오븐이나 전기오븐에 넣어서 음식물에 직접 열을 가하여 조리하거나, 음식물이 넣어진 찜용기를 가열하여 조리하거나, 또는 음식물을 전자렌지에 넣어서 고주파를 이용하여 조리하는 방법이 있다.In general, the food is cooked in a gas oven or electric oven by heating the food directly, or cooked by heating a steamed food container, or put the food in a microwave oven to There is a method of cooking using.

가스오븐이나 전기오븐에서와 같이 음식물을 직접 가열하여 조리하게 되면 음식물이 공기 중에 포함된 산소와 접촉하여 산화됨으로써 음식물의 맛이 떨어지고, 찜용기를 이용하여 조리하게 되면 음식물에 너무 많은 수분이 포함되어 음식물 특유의 맛이 떨어진다. 또한, 전자렌지로 조리를 하면 고주파가 음식물에 균일하게 주사되지 못하여 음식물이 국부적으로 타거나 덜 익게 되므로 균일한 조리를 할 수 없다. When cooking food directly by heating it, as in gas or electric ovens, food is oxidized in contact with oxygen contained in the air, and the taste of food is reduced. When cooking using a steaming container, too much water is contained in the food. The taste peculiar to food falls. In addition, when cooking with a microwave, the high frequency is not evenly injected into the food, the food is locally burned or less cooked, it is not possible to cook uniformly.

이러한 종래의 조리방법들의 단점을 해결하기 위한 대안으로 음식물에 과열증기를 공급하여 조리하는 조리장치가 개발되었는데, 과열증기를 이용하여 음식물을 조리하게 되면 음식물의 전 표면에 높은 온도의 과열증기가 직접 전달되어 음식물이 타거나 덜 익지 않게 될 뿐만 아니라 음식물 전체에 적당한 수분이 유지되어 음식물의 맛이 좋게 된다. 이러한 과열증기를 이용한 조리장치의 일례로는 일본 공개특허공보 2004-162936호가 있다. As an alternative to solve the shortcomings of the conventional cooking methods, a cooking apparatus for supplying food with superheated steam has been developed.

A fan driver 63 for driving 34 and 50, a heater driver 64 for driving various heaters 32 and 43, and a microcomputer 61 for controlling the operation of the steam cooking apparatus.

도5를 참조하여 본 발명의 일실시예에 따른 증기조리장치의 조리실 청소 방법을 설명한다. 사용자가 청소를 하기 위해 컨트롤 패널(3)의 조작스위치(5)를 이용하여 청소명령을 입력하면 급수관(23)을 통해 급수용기(22)의 물이 스팀용기(31)로 공급된다. 증기생성유닛(30)은 물이 공급되면 증기생성히터(32)를 구동하여 증기를 만든다(70).Referring to Figure 5 will be described in the cooking chamber cleaning method of the steam cooking apparatus according to an embodiment of the present invention. When the user inputs a cleaning command using the operation switch 5 of the control panel 3 to clean, the water of the water supply container 22 is supplied to the steam container 31 through the water supply pipe 23. The steam generating unit 30 generates steam by driving the steam generating heater 32 when water is supplied (70).

스팀용기(31)에서 만들어진 증기는 송풍팬(34)의 작동에 의해 스팀관(35)들을 통해 각 증기덕트(41)로 보내지고(72), 계속해서 순환팬(42)과 증기가열히터(43)의 작동에 의해 더 높은 온도의 증기로 바뀌어서 조리실(10)의 각 측면판(13)에 형성된 다수의 유출공(16)를 통해 조리실(10)로 공급된다.The steam produced in the steam container 31 is sent to each steam duct 41 through the steam pipes 35 by the operation of the blower fan 34, and then the circulation fan 42 and the steam heating heater ( By the operation of 43 is converted into a steam of a higher temperature is supplied to the cooking chamber 10 through a plurality of outlet holes 16 formed in each side plate 13 of the cooking chamber 10.

이 때 증기가열히터(43)는 일정한 주기로 온/오프를 반복하도록 한다(74). 이처럼 일정한 주기로 증기가열히터(43)를 온/오프시키는 것은 증기의 온도를 높이면서도 증기의 온도가 지나치게 상승하여 조리실(10)에 공급되는 수분이 줄어드는 것을 방지하기 위함이다. 온/오프의 반복주기는 증기가열히터(43)의 가열능력, 조리실(10)의 용적 등에 따라 적절한 값을 선택함이 바람직하다. 또한, 증기는 소정시간동안 공급하도록 설정되는데(76), 증기의 공급시간도 공급되는 증기의 온도 등에 따라 가변할 수 있는 값이다.At this time, the steam heating heater 43 repeats the on / off at a constant cycle (74). The on-off of the steam heating heater 43 at a constant cycle as described above is to prevent the water supplied to the cooking chamber 10 to decrease by increasing the temperature of the steam while increasing the temperature of the steam. The repetition cycle of on / off is preferably selected according to the heating capacity of the steam heating heater 43, the volume of the cooking chamber 10 and the like. In addition, the steam is set to be supplied for a predetermined time (76), the supply time of the steam is also a value that can vary depending on the temperature of the steam supplied.

가열된 증기의 공급과 동시에, 순환팬(42)의 작동에 의해 각 측면판(13)의 중심부에 형성된 다수의 유입공(15)을 통해 증기덕트(41)로 유입된 조리실(10) 내부의 증기는 스팀관(35)을 통해 공급되는 증기와 혼합된 후 증기가열히터(43)에 의해 다시 주기적으로 가열되어 조리실(10)로 보내지게 되는 내부순환이 이루어지게 된다.At the same time as the supply of the heated steam, the inside of the cooking chamber 10 introduced into the steam duct 41 through a plurality of inlet holes 15 formed in the center of each side plate 13 by the operation of the circulation fan 42. The steam is mixed with the steam supplied through the steam pipe 35 and then periodically heated by the steam heating heater 43 to be internally circulated to be sent to the cooking chamber 10.

또한, 흡기구(17)의 댐퍼는 개방시키고 배기관(18)의 배기 제어밸브(19)는 폐쇄시킨 상태에서 송풍팬(34)을 작동시키게 되면 조리실(10) 내의 증기가 스팀용기(31)에서 만들어진 증기와 함께 스팀관(35)들을 통해 증기공급유닛(40)으로 유동하여 조리실(10)로 복귀하게 되는 대칭적인 외부순환이 이루어지게 된다. 이처럼 한번 가열되어 조리실(10)에 공급된 증기는 내부순환 및 외부순환을 통해 다시 가열되어 조리실(10)에 공급되므로 조리실(10) 내부의 온도는 일정온도로 이상으로 유지될 수 있다.In addition, when the blower fan 34 is operated while the damper of the inlet port 17 is opened and the exhaust control valve 19 of the exhaust pipe 18 is closed, steam in the cooking chamber 10 is generated in the steam container 31. A symmetrical external circulation that flows through the steam pipes 35 through the steam pipes 35 and returns to the cooking chamber 10 is achieved. As such, once heated and supplied to the cooking chamber 10, the steam is heated again through the internal circulation and the external circulation and supplied to the cooking chamber 10, so that the temperature inside the cooking chamber 10 may be maintained at a predetermined temperature or more.

또한, 종전처럼 단순히 발생된 증기를 공급하는 것이 아니라 증기를 가열하여 온도를 상승시킨 상태에서 조리실(10)에 공급하므로 조리실(10) 내부의 음식물 찌꺼기가 잘 불려져 보다 쉽게 제거될 수 있는 상태가 된다.In addition, instead of simply supplying the generated steam as in the past, the steam is heated to supply the cooking chamber 10 in a state where the temperature is raised, so that food waste inside the cooking chamber 10 is easily called to be easily removed. .

위와 같은 과정을 거친 후에 배기제어밸브(19)를 구동하여 조리실(10) 내부의 증기를 배기시키면서 디스플레이부(4)에서 "청소가능" 기타 유사한 문구를 표시하여 사용자가(78) 청소를 하도록 안내한다. 가열증기의 공급에 의해 조리실(10) 내부의 음식물 찌꺼기가 불면 사용자는 걸레 등으로 조리실(10) 내부의 음식물 찌쩌기를 쉽게 닦아낼 수 있다.After the above process, the exhaust control valve 19 is driven to exhaust steam inside the cooking chamber 10, and the display unit 4 displays "cleanable" and other similar phrases to guide the user to clean 78. do. When food waste inside the cooking chamber 10 is blown by the supply of heated steam, the user can easily wipe the food waste inside the cooking chamber 10 with a rag or the like.

이상에서 상세히 설명한 바와 같이, 본 발명은 발생된 증기를 가열하여 조리실에 공급하였다가 청소를 하게 함으로써 조리실 내부의 음식물 찌꺼기들이 보다 쉽게 청소될 수 있도록 한다.As described above in detail, the present invention heats the generated steam to be supplied to the cooking chamber and cleans the food wastes inside the cooking chamber more easily.
