본 발명은 전자렌지의 해동물 온도무게 감지장치에 관한 것으로서, 더욱 상세하게는 해동기능을 구비한 전자렌지에 있어서 복수의 고주파 감지센서를 이용하여 냉동식의 온도와 무게를 정확히 판별하여 해동할 수 있도록 하는 전자렌지의 해동물 온도무게 감지장치에 관한 것이다.The present invention is the microwave temperature of the microwave The present invention relates to a weight sensing device, and more specifically, to a microwave oven having a thawing function, by using a plurality of high frequency sensing sensors, the temperature of the frozen food and the temperature of the microwave can be thawed by accurately determining the weight of the microwave. It relates to a weight sensing device.

종래의 전자렌지는 제1도에 도시된 바와 같이, 냉동식품(3)을 얹어주는 트레이(4)가 구비된 조리실(1)과, 이 냉동식품(3)이 골고루 가열되도록 트레이(4)를 회전시켜 주는 턴테이블 모터(5)와, 조리실(1)로 공급되는 고주파를 발진시키는 마그네트론(2)과, 냉동식품(3)의 온도와 무게를 감지하는 고주파 감지센서(6)와, 이 고주파 감지센서로부터 전기적 신호를 입력받아 처리하는 마이콤(7)을 갖추고 있다.In the conventional microwave oven, as shown in FIG. 1, the cooking chamber 1 including the tray 4 on which the frozen food 3 is placed, and the tray 4 are evenly heated so that the frozen food 3 is evenly heated. A turntable motor 5 for rotating, a magnetron 2 for oscillating the high frequency supplied to the cooking chamber 1, a high frequency sensor 6 for sensing the temperature and weight of the frozen food 3, and this high frequency sensing It is equipped with the microcomputer 7 which receives and processes an electrical signal from a sensor.

위와 같은 전자렌지의 행동과정은, 마그네트론(2)으로부터 발생되는 고주파가 조리실(1)내로 공급되어 냉동식품(3)에 흡수되는데, 이 과정에서 냉동식품(3)에 투사되어 냉동식품(3)을 투과한 고주파와 냉동식품(3)에 투사되지 않은 고주파는 고주파 감지 센서(6)로 감지하여 전기적 신호로 마이콤(7)에 전달하여 주며, 냉동식품(3)의 균등한 가열을 위해 모터(5)가 구동되어 트레이(4)를 회전시켜 준다.The behavior of the microwave oven as described above, the high frequency generated from the magnetron (2) is supplied into the cooking chamber (1) and absorbed by the frozen food (3), in this process is projected on the frozen food (3) frozen food (3) The high frequency transmitted through the light and the high frequency which is not projected on the frozen food 3 are detected by the high frequency sensor 6 and transmitted to the microcomputer 7 as an electrical signal. 5) is driven to rotate the tray (4).

이렇게 되면, 마이콤(7)은 고주파 감지센서(6)로부터의 전기적 신호의 레벨에 따라 냉동식품(3)의 온도와 무게를 판단하여 행동과정을 진행하게 된다.In this case, the microcomputer 7 judges the temperature and weight of the frozen food 3 according to the level of the electrical signal from the high frequency sensor 6 to proceed with the course of action.

그러나, 마이콤(7)에는 -20의 냉동식품(3)을 해동시키는 프로그램이 입력되어 있으므로 냉동식품(3)의 초기 온도가 -20가 아닌 경우 고주파 감지센서(6)의 전기적 신호의 레벨은 냉동식품(3)의 초기 온도와 무게를 정확히 반영하지 못한다.However, the microcomputer 7 has -20 Since the program for thawing frozen food (3) is inputted, the initial temperature of frozen food (3) is -20. If not, the level of the electrical signal of the high-frequency sensor 6 does not accurately reflect the initial temperature and weight of the frozen food (3).

즉, 제3도에 있어서 마이콤에 입력된 프로그램은 -20냉동식품의 데이터를 기준으로 만들어진 것인데, -10의 300그램의 냉동식품을 해동하고자 하면 -20의 500그램의 냉동식품에 해당하는 센서 레벨(Y1)이 검출되어 마이콤에서는 -20의 500그램의 해동코스를 진행하므로 해동시간이 길어지고 이에 따른 전력소비가 증가하는 문제점이 있었다.That is, the program input to the microcomputer in FIG. 3 is -20. Based on frozen food data, -10 To thaw 300 grams of frozen food Sensor level (Y1) corresponding to 500 grams of frozen food is detected, Since the defrosting course of 500 grams of the defrost time is longer, there is a problem that the power consumption increases accordingly.

본 발명은 상기와 같은 종래의 전자렌지의 해동과정에 있어서 냉동식품의 초기 온도와 무게를 하나의 고주파 감지센서만으로는 정확히 감지하지 못하여 해동시간이 늘어나고 전력소비가 증가되는 문제점을 해결하기 위해 안출된 것으로, 복수의 고주파 감지센서를 이용하여 냉동식품의 온도와 무게를 정확히 판별하여 해동할 수 있도록 하는 전자렌지의 냉동식품의 온도무게 감지장치를 제공함을 목적으로 한다.The present invention is to solve the problem that the thawing time is increased and the power consumption is increased because the initial temperature and weight of the frozen food in the thawing process of the conventional microwave as described above does not accurately detect only one high-frequency sensor. Temperature of the frozen food in the microwave to accurately thaw the temperature and weight of the frozen food using a plurality of high-frequency sensors It is an object to provide a weight sensing device.

이러한 본 발명의 목적은, 조리실의 온도변화 특성이 다른 부위에 복수의 고주파 감지센서를 장착함으로써, 초기 온도 판단에 대한 오차를 최대한 줄임으로써 달성된다.This object of the present invention is achieved by minimizing the error of the initial temperature determination by mounting a plurality of high-frequency detection sensors in different parts of the temperature change characteristic of the cooking chamber.

이하, 본 발명의 실시예를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 발명의 실시예에 따른 전자렌지를 보인 개략적인 단면도로서, 냉동식품(30)을 넣는 조리실(10)과, 이 조리실(10)로 공급되는 고주파를 발진시키는 마그네트론(20)과, 이 마그네트론(20)에서 발진되는 고주파를 이용하여 냉동식품(30)을 균등하게 가열시키기 위해 회전하는 트레이(40)와, 이 트레이를 회전시키는 모터(50)와, 조리실(10)의 온도변화 특성이 다른 부위에 설치되어 잔류 고주파와 냉동식품(30)을 투과한 고주파를 감지하여 전기적 신호를 출력하는 복수의 고주파 감지센서(60)(61)와, 이들 고주파 감지센서로부터 전기적 신호를 입력받아 해동과정을 수행하는 마이콤(70)으로 구성된다.2 is a schematic cross-sectional view showing a microwave oven according to an embodiment of the present invention, a cooking chamber 10 containing a frozen food 30, a magnetron 20 for oscillating a high frequency supplied to the cooking chamber 10, Temperature change characteristics of the tray 40 which rotates to evenly heat the frozen food 30 using the high frequency oscillated by the magnetron 20, the motor 50 which rotates the tray, and the cooking chamber 10. A plurality of high frequency detection sensors (60) and (61) installed at the other part and detecting the high frequency transmitted through the residual high frequency and the frozen food (30) and outputting an electrical signal, and thawing by receiving electrical signals from these high frequency detection sensors It consists of a microcomputer 70 for performing the process.

고주파 감지센서(60)(61)들은 조리실(10)의 온도변화 특성이 다른 부위에 장착되는데, 이때 온도변화 특성이 다른 부위라 함은 전계와 자계에 의해 진행하는 고주파가 조리실(10) 내부에 집중되어지는 곳을 말한다.The high frequency detection sensors 60 and 61 are mounted at different parts of the temperature change characteristic of the cooking chamber 10. In this case, the parts having different temperature change characteristics are inside the cooking chamber 10. It is a place of concentration.

이와 같이 구성되는 본 발명의 실시예에 따른 전자렌지의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effect of the microwave oven according to the embodiment of the present invention configured as described above are as follows.

먼저, 조리실(10)내에 냉동식품(30)을 넣고 해동을 시작하는 버튼을 누르면, 마이콤(70)의 제어에 따라 마그네트론(20)이 동작된다.First, when the frozen food 30 is put into the cooking chamber 10 and the button for starting thawing is pressed, the magnetron 20 is operated under the control of the microcomputer 70.

이렇게 되면, 마그네트론(20)이 구동됨에 따라 조리실(10) 내부로 고주파가 공급되는 한편, 모터(50)가 구동되어 냉동식품(30)이 놓여진 트레이(40)를 회전시키며, 조리실(10)로 공급되는 고주파는 냉동식품(30)에 흡수되어 이 냉동식품을 가열하게 된다.In this case, as the magnetron 20 is driven, a high frequency is supplied into the cooking chamber 10, while the motor 50 is driven to rotate the tray 40 on which the frozen food 30 is placed, and to the cooking chamber 10. The high frequency supplied is absorbed by the frozen food 30 to heat the frozen food.

이러한 과정에서, 냉동식품(30)에 투사되지 않고 남는 고주파와 냉동식품(30)에 투사되었으나 투과한 고주파가 온도변화 특성이 다른 부위에 장착되어 있는 고주파 감지센서(60)(61)들에 감지된다.In this process, the high frequency that is not projected onto the frozen food 30 and the high frequency that is projected onto the frozen food 30 are transmitted to the high frequency detection sensors 60 and 61 that are mounted at different temperature change characteristics. do.

이에 따라, 고주파 감지센서(60)(61)들은 감지내용을 전기적 신호로 마이콤(70)에 전달하게 되고, 이 마이콤은 그 신호를 입력받아 냉동식품(30)의 온도와 무게를 판별하여 전자렌지가 정해진 해동코스를 진행토록하여 준다.Accordingly, the high frequency detection sensors 60 and 61 transmit the detected contents to the microcomputer 70 as an electrical signal, and the microcomputer receives the signal to determine the temperature and weight of the frozen food 30 and microwave. Allow the defrosting course to proceed.

한편, 고주파 감지센서(60)(61)들은 냉동식품(30)의 온도와 무게에 따라 레벨이 다른 특성을 나타내게 된다.On the other hand, the high-frequency sensor 60, 61 will exhibit a different level depending on the temperature and weight of the frozen food (30).

즉, 제3도는 고주파 감지센서(60)의 레벨과 냉동식품의 무게와의 비교를 나타낸 것으로, 냉동식품(30)의 무게에 따라 전압으로 나타나는 전계의 세기가 변화되는 것을 나타낸다.That is, FIG. 3 shows a comparison between the level of the high frequency sensor 60 and the weight of the frozen food, and shows that the intensity of the electric field represented by voltage changes according to the weight of the frozen food 30.

제4도는 고주파 감지센서(61)의 레벨과 냉동식품의 무게와의 비교를 나타낸 것으로, 냉동식품(30)의 무게에 따라 전계의 세기는 변화하지 않고 전계모드의 위치가 변화하는 것을 나타낸다.4 shows a comparison between the level of the high frequency sensor 61 and the weight of the frozen food, and shows that the position of the electric field mode is changed without changing the intensity of the electric field according to the weight of the frozen food 30.

따라서, 냉동식품(30)의 상태가 -20의 300그램이라 가정을 하면, 고주파 감지센서(60)의 레벨값은 Y2이고, 고주파 감지센서(61)의 레벨값은 Y4로써 300그램을 인식한다.Therefore, the state of the frozen food 30 is -20 If it is assumed that 300 grams, the high frequency sensor 60 is a level value of Y2, the high frequency sensor 61 is a level value of Y4 to recognize 300 grams.

한편, 냉동식품(30)의 상태가 -10의 300그램이라 가정을 하면, 고주파 감지센서(60)의 레벨값은 Y1이고, 고주파 감지센서(61)의 레벨값은 Y3로써 300그램을 인식한다.On the other hand, the state of the frozen food 30 is -10 If it is assumed that 300 grams, the high-frequency detection sensor 60 of the level value is Y1, the high-frequency detection sensor 61 of the level value is Y3 to recognize 300 grams.

만약, -20의 500그램의 냉동식품(30)을 해동시킨다고 하면, 상기와 같은 방법으로 제3도와 제4도에서 Y1 값과 Y5 값이 인식되어 500그램대의 시간으로 해동을 시작한다.If -20 If the 500 grams of frozen food 30 is thawed, Y1 and Y5 values are recognized in FIGS. 3 and 4 in the same manner as described above, and the thawing begins at 500 grams of time.

이와 같이 본 발명은, 조리실(10)의 온도변화 특성이 각기 다른 부위에 복수의 고주파 감지센서(60)(61)를 장착하여 전자렌지의 해동기능 동작시 냉동식품(30)의 초기 온도와 상관없이 정확한 냉동식품(30)의 무게를 감지하고 온도변화에 대한 오차를 최대한 줄여 해동시간과 전력소비를 줄일 수 있는 효과가 있다.As described above, the present invention is equipped with a plurality of high-frequency detection sensors 60 and 61 at different parts of the temperature change characteristic of the cooking chamber 10 to correlate with the initial temperature of the frozen food 30 during the thawing function of the microwave oven. Without detecting the exact weight of the frozen food 30, and by reducing the error for the temperature change to the maximum has the effect of reducing the thawing time and power consumption.
