る。Structure of conventional hook and its problems In FIG. 1, 1 is a gas inlet, and gas passes through a cock 2' and is burned in a burner 3. 4 is a trivet on which a cooking container is placed, and 5 is a gas stove consisting of these. 6 is a pressure cooker, which is heated by a burner 3. 7 is a food to be cooked in the pressure cooker 6. Reference numeral 16 designates the lid of the pressure cooker 6, which is provided with a fastener 17 at the center of the lid and a gasket 18 made of a heat-resistant material around the lid, which seals the lid with the pressure cooker 6 during use. Reference numeral 19 denotes a pressure regulator, which is fixed to the lid 16 and has one end directed into the pressure cooker 6 and the other end exposed to the atmosphere, and releases steam from a small hole (not shown) during heating to adjust the pressure inside the pressure cooker 6. It keeps the pressure constant. 20
is a safety valve, which is similarly fixed to the lid 16, with one end directed into the pressure cooker 6 and the other end exposed to the atmosphere, and which releases steam when the pressure inside the pressure cooker 6 exceeds the allowable pressure. It lowers the pressure inside the pressure cooker 6. 21 is a lid support;
The lid 16 can be brought into close contact with the pressure cooker 6 by installing both ends onto the upper end 6 of the pressure cooker 6 and tightening the fasteners 17.
従来、圧力鍋6を使用してシチュー、カレー等の煮込み

なければならす、蒸気の持去る熱量及び連続加熱のため
の燃料費か高くつき、無駄なエネルギー消費になるとと
もに室内へ多量の蒸気が放出され室内汚染の原因となる
という欠点があった。Conventionally, when the pressure cooker 6 is used to stew stew, curry, etc., or boil potatoes, the pressure inside the pot increases, so the boiling point of water becomes high and cooking can be done in a relatively short time. However, in order to adjust the pressure inside the pressure cooker 6, steam must always be released from the pressure regulator 19 to the outside of the pot during heating and boiling, which is wasteful due to the amount of heat carried away by the steam and the fuel cost for continuous heating. This has the disadvantage that it consumes a lot of energy and releases a large amount of steam into the room, causing indoor pollution.
そこで内容物の温度を検出して、内容物が煮立った時に
、自動的に火力を調整する自動制御装置が考えられる。Therefore, an automatic control device that detects the temperature of the contents and automatically adjusts the firepower when the contents boil is considered.

であった。However, inserting a temperature sensor into a cooking pot to detect the temperature of the contents is inconvenient, difficult to seal the pot, and feels unclean. For this reason, a method has been devised in which a temperature sensor is brought into contact with the bottom of a cooking pot to detect the bottom temperature of the pot and to infer the temperature of the contents. However, this method had the disadvantage that the temperature at the bottom of the pot and the temperature of the contents were not constant and varied depending on the material and shape of the pot, the type and amount of contents, etc. Therefore, it is difficult to accurately detect when the temperature of the contents reaches the boiling point and then adjust the temperature to a constant temperature within a small range.

ことを目的とする。Purpose of the Invention The present invention is a cooking temperature control device that detects the temperature at the bottom of a pressure cooker, which can be set regardless of the type and amount of contents, especially when the internal temperature is controlled to a boiling state when cooking with a lot of water such as boiling or stewing. Moreover, by controlling the amount of heating, the purpose is to prevent the release of excess steam, save energy, and maintain the safety of the appliance by keeping the pressure inside the pot constant.

The temperature at that time is set as the set temperature, and the temperature is adjusted within a small range with respect to the set temperature by varying the amount of heating.

御する。The dregs pass from the dregs population 1 through an on-off valve 2 and are burned in a burner 3. The burner 3 heats the bottom of the pressure cooker 6 and adds heat to the cooked food 7. 8 is a temperature sensor that detects the bottom surface temperature of the pressure cooker 6, and this signal is input to the temperature detection section 9;
The temperature is transmitted to the temperature control section 10. The temperature control section 10 includes an inclination detection section 11, a bending point detection section 12, and a heat amount control section 13, and controls the combustion amount of the burner 3 by driving the on-off valve 2.
さて本発明では、水は圧力鍋内の圧力がきまればある一

着眼し、鍋底温度の傾斜の屈曲点を検出する構成とした
。Now, in the present invention, once the pressure inside the pressure cooker is determined, water will boil at a certain temperature and will not rise any further. (For example, at a gauge pressure of 1 kg/cyA, it boils at about 119°C.) Similarly, we focused on the fact that the temperature rise at the bottom of the pressure cooker would also be reduced, and we designed a structure that detects the bending point of the slope of the bottom temperature.

温度を示し、図は、圧力鍋6で場を沸かした時の特性例
でAは内容物の温度つまり水温、Bは鍋底の温度つまり
温度センサ8による検知温度を示す。Figure 4 shows the temperature rise characteristics, with the horizontal axis X representing time and the vertical axis T representing temperature. The figure shows an example of the characteristics when a pressure cooker 6 is used to boil the area, where A is the temperature of the contents, that is, water temperature, and B indicates the temperature at the bottom of the pot, that is, the temperature detected by the temperature sensor 8.

ばらつく。しかし、温度上昇の傾斜が変化する屈曲点C
は、常に水温Aが沸騰してからである。The temperature Ta is at a moderate temperature and increases in both curves A and B due to heating. The temperature B detected by the temperature sensor 8 has a gradual rising curve once at the temperature Tb, and then begins to rise again from the temperature Tf. This is because dew condenses on the bottom of the pan at temperatures around Tb to Tf and evaporates. Temperatures Tb to Tf are approximately 40 to 70'C, although this varies depending on the size and material of the pan 4. Furthermore, the temperature continues to rise until the temperature Tc reaches approximately 119°C, and the water temperature A boils and does not rise above 119°C. The sensor temperature B at this time is Td. Td and water temperature A are 119
From the point at which the temperature rises to °C, the rate of rise becomes very small or disappears. The temperature difference between this Tc point 119℃ and Td is the temperature difference between the pot 6
It varies greatly depending on the type of food (material and thickness), amount and type of food being cooked. However, the inflection point C where the slope of temperature rise changes
is always after the water temperature A has boiled.
また、温度Tb−Tfによる屈曲を屈曲点検知部12が
検知しないように、屈曲点検知部12は、測定開始温度
Tf以上(温度上昇が安定した温度)か・ら動作する構
成とすることにより屈曲点検出ミスがなくなる。Furthermore, in order to prevent the bending point detection unit 12 from detecting the bending caused by the temperature Tb-Tf, the bending point detection unit 12 is configured to operate from the measurement start temperature Tf or higher (a temperature at which the temperature rise is stable). Eliminates bending point detection errors.
ここで、第4図のTb点を越えた点Tfで一定時間間隔
ΔXAの温度上昇傾斜Txを測定し、この傾斜Twを関
数として屈曲値Tuを演算する。Here, the temperature increase slope Tx at a constant time interval ΔXA is measured at a point Tf exceeding point Tb in FIG. 4, and the bending value Tu is calculated using this slope Tw as a function.
この屈曲値Tuは屈曲点検知部12でΔTと比較し、Δ
TがTuより小さくなる点で屈曲点Cを判定する。This bending value Tu is compared with ΔT in the bending point detection unit 12, and Δ
The bending point C is determined at the point where T is smaller than Tu.

理に適し弱火で時間をかけて煮込むことができる。The heat amount control section 13 controls the combustion amount from 1 ON to OFF based on the signal from the bending point detection section 12, or controls the amount of combustion to be further heated with a small amount of calories, which is generally suitable for simmering and takes a long time over low heat. It can be boiled.

The temperature change ΔT is sequentially measured from m-Tn, and the bending point detection unit 12 determines that the point where ΔT becomes equal to or less than the bending value Tu is the bending point, and the content temperature is determined at the temperature Td at that time. This is a method of setting the temperature to 119°C.

。Figure 6 shows this control characteristic, where the horizontal axis X is time, the vertical axis T of characteristic V is temperature, the broken line A is the temperature of the contents as in Figure 4, and the solid line B is the sensor temperature characteristic at the bottom of the pot. . The vertical axis I of the characteristic W indicates rONJ [○FFJ] of the on-off valve 2, which is interlocked with "ON"[OFF'J] of the burner 3. Until time Xd, the on-off valve 2 is in the "ON" state and the burner 3 continues combustion before the signal from the bending point detection section 12 shown in FIG. 5 is output. When the internal temperature reaches the Tc point of 119° C. at time Xd and boiling begins, the bending point detection unit 12 detects this and turns the on-off valve 2 “OFF” to stop combustion. At this time, the temperature Td is set as the set temperature in the heat quantity control section 13.

し、短時間で調理を行うことかできる。For example, if the value of the set temperature Td is 130°C, the on-off valve 2 can actually be operated at 130°C and 127°C. In other words, turn off the on-off valve 2 at Td=13o'c.
JL, stop combustion. At Tdi -127°C, the on-off valve 2 is turned “QN” and combustion is started. As the sensor temperature B changes in this way, the temperature of the contents also follows. In other words, there is a slight temperature change between Tc and Tc1, but there is no problem during actual use, and compared to other pots, cooking can be done in a shorter time.

なるため蒸気による室内汚染を防止できる。When the temperature of contents A is Tc, steam is released from the pressure regulator 19, and when it is Tc1, the amount of steam released is smaller, resulting in less wasteful use of thermal energy compared to conventional pressure cookers. At the same time, since the amount of steam released is reduced, indoor contamination due to steam can be prevented.

detect a decrease in The calorie control unit 13 detects this temperature Te, turns on the on-off valve 2, and automatically restarts combustion. Although the combustion control by turning the on-off valve 2 ON and OFF has been explained above, the purpose can also be achieved by controlling the combustion amount using a proportional valve.

温度が沸騰点に達したことを検出する構成であるため調
理物の温度とセンサ温度との関係が一定でなくとも、正
確に沸騰点の検出が可能である。Effects of the Invention As described above, the temperature-controlled pressure cooker of the present invention measures the slope of temperature rise of the food during simmering, changes the bending value according to the slope, and detects the bending point. Since the structure detects when the temperature of the food to be cooked has reached the boiling point, the boiling point can be accurately detected even if the relationship between the temperature of the food and the sensor temperature is not constant.
また、傾斜や屈曲点の検知方法は、一定の定められた時

ステムを構成できる。In addition, the method for detecting inclinations and bending points is to obtain the difference in sensor temperature by sampling at fixed time intervals, which makes it easy to control with a microcomputer, etc., and allows accurate bending point detection just by processing a program. This makes it easy to configure the system.
さらに前記傾斜の検知は、センサ温度が予め定められた

屈曲点(沸騰点)の検出ができる。Furthermore, the tilt detection starts from the point where the sensor temperature reaches a predetermined temperature or higher, so that even if there is tilt fluctuation due to water condensing on the bottom of the pot during the initial heating stage, it is ignored, ensuring a stable and reliable tilt detection. can be detected and therefore
The bending point (boiling point) can be detected.

できる。In addition, by having a heat amount control unit that controls the on-off valve using the sensor temperature at the bending point as the set temperature, once it has boiled, it is possible to automatically change the heat amount and simmer while maintaining the temperature, and further add ingredients etc. If the temperature drops, the amount of combustion is automatically increased and the original temperature is restored in a short time. Therefore, stewing can be done safely in a short time without any failures such as burning or boiling over, and it also prevents unnecessary heating and saves energy. In other words, since the amount of steam released from the pressure cooker is reduced, thermal energy can be saved, and accidents such as indoor contamination due to steam and burns can be prevented.
また、鍋底が温度センサに接していれば調理物の多少や
鍋の形状に関係なく沸騰を検知することができる。Furthermore, if the bottom of the pot is in contact with the temperature sensor, boiling can be detected regardless of the amount of food being cooked or the shape of the pot.
