본 발명은 유아들에게 우유를 먹일 경우에 사용하는 젖병을 전자레인지로 멸균소독하는 전자레인지를 이용한 젖병 소독방법에 관한 것으로, 특히 가스센서의 동작특성을 이용하여 자동으로 젖병을 멸균소독하는 전자레인지를 이용한 젖병 소독방법에 관한 것이다.The present invention relates to a bottle disinfection method using a microwave oven for sterilizing the bottle used in the case of feeding the infant milk in a microwave oven, in particular a microwave oven for sterilizing the bottle automatically using the operating characteristics of the gas sensor It relates to a bottle disinfection method using.

일반적으로 유아들에게 우유를 먹일 경우에 젖병을 사용하고 있다. 그리고 우유에는 황색 포도상구균에 쉽게 침투하여 활성화되므로 유아에게 우유를 먹인 젖병은 다시 우유를 넣어 먹이기 전에 먼저 멸균소독을 하여 유아들이 황색 포도상 구균에 감염되지 않도록 해야 된다.Generally, feeding bottles are used for feeding infants. In addition, milk is easily penetrated by Staphylococcus aureus, so the baby bottle fed with milk should be sterilized before feeding the milk again so that infants are not infected with Staphylococcus aureus.

젖병을 멸균소독하기 위하여 종래에는 소독기나 남비등이 그릇내에 물과 함께 젖병을 넣고, 이를 가열하여 끓이며, 물이 끓기 시작하여 소정의 시간이 경과될 경우에 멸균소독을 정지하였다.In order to sterilize the bottle, a sterilizer or a pot is put in a bowl together with water in a bowl, and the bottle is heated and boiled, and sterilization is stopped when a predetermined time has elapsed since the water starts to boil.

그러나 상기와 같이 물을 끓여 멸균소독하는 방법은 소독자에게 많은 번거로움을 줄 뿐만 아니라 잘못하면 끓는 물에 의해 화상을 입게 되며, 필요이상으로 물을 끓여 열량의 손실이 많은 문제점이 있었다.However, the method of sterilizing and sterilizing water as described above not only causes a lot of trouble to the sterilizer but also causes a burn by boiling water if there is a mistake, and boils water more than necessary, causing a lot of heat loss.

그리고 전자레인지를 이용하여 젖병을 멸균소독하는 방법으로 젖병내에 약간의 물을 넣어 가열실에 내장하고, 임의로 시간 및 출력레벨을 설정한 후 동작시키고 있으나, 젖병이 정확하게 멸균소독되었는지 또는 너무 과다하게 시간을 설정하여 필요없이 많은 전력이 소모되었는지를 판별할 수 없고, 과다하게 시간을 설정하였을 경우는 젖병이 과열되어 녹아버리게 됨은 물론 멸균소독할 젖병의 수량과 젖병내에 넣은 물의 양에 따라 시간 및 출력레벨을 상이하게 설정해야 되는 등 소독자가 세심한 주의를 기울여야 되는 등의 문제점이 있었다.And by using a microwave to sterilize the bottle by putting a little water in the bottle into the heating chamber, and optionally set the time and output level, but the operation is correct, sterilized or too much time It is not possible to determine whether much power is consumed without setting, and if the time is set excessively, the bottle becomes overheated and melts, as well as the time and output level depending on the number of bottles to be sterilized and the amount of water in the bottle. There was a problem that the sterilizer should pay close attention such as to be set differently.

본 발명은 상기와 같은 종래의 제반 문제점들을 해결하기 위하여 창안한 것으로서, 수분의 변화에 따른 가스센서의 저항율 변화와 끓는 물에서의 황색 포도상 구균의 사멸율을 이용하여 젖병을 자동으로 멸균소독하는 것으로 가스센서의 초기저항과 물의 가열에 따라 발생되는 수분의 농도에 따른 검출저항의 비를 나타내는 △G값으로 물이 끓는지를 판별하고, 물의 끓음이 판별될 경우에는 설정 멸균소독 시간동안 전자레인지를 계속 동작시켜 멸균소독함으로써 소독자의 번거로움이 없이 젖병을 자동으로 정확히 멸균소독하는 젖병 소독방법을 제공하는데 그 목적이 있는 것으로 이를 첨부된 도면을 참조하여 상세히 설명한다.The present invention has been made to solve the above-mentioned conventional problems, to automatically sterilize the bottle using the change in the resistivity of the gas sensor according to the change of moisture and the killing rate of Staphylococcus aureus in boiling water. Determine whether the water is boiling by △ G value which indicates the ratio of the initial resistance of the gas sensor and the detection resistance according to the concentration of moisture generated by heating the water.If the boiling of water is determined, the microwave is continued for the set sterilization time. Sterilization by operating sterilization without the hassle of disinfecting the bottle automatically provides a sterilization method for sterilizing the bottle accurately, the purpose of which will be described in detail with reference to the accompanying drawings.

제1도는 본 발명의 젖병 소독방법이 적용되는 전자레인지의 제어회로도로서 이에 도시된 바와같이, 가스센서(GS)로 가열실의 수분변화를 검출하는 검출부(1)와, 전자레인지의 동작을 제어하고 상기 검출부(1)의 출력신호로 물의 온도를 판별하면서 젖병의 소독을 제어하는 제어부(2)와, 상기 제어부(2)의 제어에 따라 고주파를 발생시켜 가열실에 내장된 피가열물을 가열하는 고주파 가열부(3)로 구성하였다.1 is a control circuit diagram of a microwave oven to which the baby bottle disinfecting method of the present invention is applied, and as shown therein, a detection unit 1 for detecting a change in moisture in a heating chamber by a gas sensor GS, and controlling the operation of the microwave oven. The controller 2 controls the disinfection of the bottle while the temperature of the water is determined by the output signal of the detector 1, and a high frequency is generated according to the control of the controller 2 to heat the heated object built in the heating chamber. It consists of the high frequency heating part 3.

제1도의 도면 설명중 미설명부호 R은 저항이고, B+는 전원이며, IN은 입력단자이다.In FIG. 1, reference numeral R denotes a resistor, B + denotes a power supply, and IN denotes an input terminal.

여기서, 가스센서(GS)는 수분의 농도가 높아짐에 따라 저항값이 감소되는 부성저항 특성을 가진 소자로서 젖병에 물을 넣고 가열할 경우에 △G(△G=초기저항값/검출저항값) 특성곡선은 제2도의 (가)에 도시된 바와 같이 가변되고, 물의 온도가 약 100℃로 끓을 경우에 △G의 값은 약 1.4로 되며, 젖병에 물을 넣지 않은 상태에서 전자레인지를 동작시킬 경우에는 발생되는 수분이 없어 △G의 값은 제2도의 (나)에 도시된 바와 같이 거의 변동이 없게 된다.Here, the gas sensor GS is a device having a negative resistance characteristic that the resistance value decreases as the concentration of water increases. When the water is put into a baby bottle and heated, ΔG (ΔG = initial resistance value / detection resistance value) The characteristic curve is variable as shown in (A) of FIG. 2, and when the water temperature boils at about 100 ° C, the value of ΔG becomes about 1.4, and the microwave oven is operated without the water in the bottle. In this case, there is no moisture generated, so that the value of ΔG is almost unchanged as shown in FIG.

이와 같은 구성의 전자레인지에 적용되는 본 발명의 젖병 소독방법은 젖병을 소독할 경우에 먼저 젖병에 약간의 물 즉, 약 50㏄정도의 물을 넣어 전자레인지의 가열실에 내장하고, 젖병 소독명령을 한다.The bottle disinfection method of the present invention applied to the microwave oven having such a configuration, when disinfecting the bottle, first puts a little water, that is, about 50 kPa of water, into the heating chamber of the microwave oven, and disinfects the bottle. Do it.

그러면 제어부(2)는 제 3 도에 도시된 바와같이 젖병 소독을 판단하고, 고주파 가열부(3)가 고주파를 발생하게 하여 젖병을 가열하면서 가열시간(t1)을 카운트하고, 입력단자(IN)에 인가되는 검출부(1)의 검출신호 즉, 젖병의 가열에 따른 가스센서(GS)의 신호를 입력하여 △G의 값을 계산한 후 △G의 값이, 젖병의 물이 100℃로 끓는 온도인 1.4이상으로 되는지를 판단한다.Then, the controller 2 determines the disinfection of the bottle as shown in FIG. 3, causes the high frequency heating unit 3 to generate a high frequency, counts the heating time t1 while heating the bottle, and inputs the terminal IN. After inputting the detection signal of the detection unit 1, that is, the signal of the gas sensor GS according to the heating of the bottle, the value of ΔG is calculated and the value of ΔG is the temperature at which the water of the bottle boils at 100 ° C. It is judged whether it becomes more than 1.4.

이때 △G의 값이 1.4이상이 아닐 경우에는 가열시간(t1)이 설정시간 이상으로 경과 즉, 약 150초 이상 젖병을 가열하였는지를 판단하고, 150초가 경과되지 않았을 경우에는 입력단자(IN)에 인가된 신호를 입력하고, △G의 값을 계산하여 1.4이상으로 되는지를 판단하는 동작을 반복하여, 설정된 150초가 경과되어도 △G의 값이 1.4이상으로 되지 않을 경우에는 가열동작을 정지한다.At this time, if the value of ΔG is not more than 1.4, it is determined whether the heating time t1 is longer than the set time, that is, whether the bottle is heated for about 150 seconds or more, and if it is not 150 seconds, it is applied to the input terminal IN. The input signal is inputted, the operation of calculating the value of? G and determining whether it is 1.4 or more is repeated. When the value of? G does not become 1.4 or more even after the set 150 seconds has elapsed, the heating operation is stopped.

여기서, 설정된 150초는 젖병에 물을 넣고 고주파로 가열할 경우에 물의 온도가 100℃로 끓게 되는 충분한 시간으로서 150초 이상이 경과되어도 △G의 값이 1.4이하일 경우에는 젖병에 물이 없는 것이므로 가열을 정지하여 젖병이 과열 및 손상되는 것을 방지하기 위한 것이다.Here, the set 150 seconds is a sufficient time for the water temperature to boil at 100 ℃ when the water is put into the bottle and heated at a high frequency. Even if 150 seconds or more elapses, when the value of ΔG is 1.4 or less, the bottle does not have water. To stop the bottle from overheating and being damaged.

그리고 설정된 150초가 경과되기 전에 △G값이 1.4이상으로 되면, 젖병의 멸균소독을 수행하는 것으로 가열시간(t1)은 클리어시키고, 멸균소독시간(t2)을 카운트하며, 멸균소독시간(t2)이 설정시간 이상 즉, 40초 이상으로 되는지를 판별하여 40초가 경과될 경우에는 젖병의 가열을 정지하고, 멸균소독을 완료한다.When the ΔG value is 1.4 or more before the set 150 seconds have elapsed, sterilization of the bottle is performed to clear the heating time (t1), count the sterilization time (t2), and sterilization time (t2). If 40 seconds elapses after determining whether it is more than the set time, that is, 40 seconds or more, the heating of the bottle is stopped and sterilization is completed.

여기서 젖병의 멸균소독시 사멸되는 황색 포도상 구균의 사멸율을 살펴보면, 제4도에 도시된 그래프와 같이 100℃의 온도조건하에서 약 40초의 시간이 경과되면 황색 포도상 구균이 100% 사멸되는 것으로 본 발명은 △G의 값이 1.4로 물의 온도가 100℃일 경우에 약 40초간 계속 젖병을 가열하여 멸균소독하고, 이때 젖병내의 물에 잠긴 부위는 100℃의 끓는 물에 의해 멸균소독되고, 젖병내의 물에 잠기지 않는 부위는 100℃의 끓는 물에 의해 발생되는 고온의 수증기에 의해 멸균소독되며, 젖병의 외부면은 젖병 내부온도의 열전도로 멸균소독된다.Looking at the killing rate of Staphylococcus aureus killed during sterilization of the bottle, as shown in the graph shown in Figure 4, the staphylococcus aureus is 100% killed when the time of about 40 seconds elapsed under the temperature conditions of 100 ℃ When the value of ΔG is 1.4 and the water temperature is 100 ° C., the bottle is continuously sterilized by heating for about 40 seconds. At this time, the submerged part of the bottle is sterilized by boiling water at 100 ° C. and the water in the bottle is sterilized. The non-immersed area is sterilized by hot steam generated by boiling water at 100 ° C., and the outer surface of the bottle is sterilized by heat conduction of the inside temperature of the bottle.

이상에서 상세히 설명한 바와 같이 본 발명은 가스센서를 이용하여 물이 끓는 시점을 판단하고, 물이 끓는 시점부터 황색 포도상 구균이 100% 사멸되는 시간동안 계속 가열하여 멸균소독을 수행한 후 정지하므로 젖병의 멸균소독시 소독자의 번거로움 및 세심한 주의를 기울여야 되는 것을 제거하고, 젖병을 정확히 멸균소독할 수 있음은 물론 젖병을 과소독하여 열량이나 전력이 필요없이 소모되는 것을 방지할 수 있는 효과가 있다.As described in detail above, the present invention uses a gas sensor to determine the time of boiling water, and from the time of boiling water, since the stagnant sterilization is continued by heating for a time when 100% of Staphylococcus aureus is killed, When disinfecting sterilization, it is possible to remove the troublesome and careful attention of the sterilizer, and to sterilize the bottle accurately, as well as to over-disinfect the bottle to prevent consumption of calories or power.
