The heating of the heating means is started at or before the point in time at which the predetermined time is calculated. In addition, the invention of claim 9 of the present application is related to the rice cooker of claim 1, wherein the pressure valve is connected to the pressure hole of the inside and outside of the pot and in the boiling maintaining step. When the boiled material is heated, the ball of the pressure hole is closed, and the ball is forcibly moved by the pressure valve opening mechanism to open the pressure hole. In addition, the invention of claim 10 of the present application is related to the rice cooker of the ninth application of the patent scope, wherein the opening area of the pressure hole is 6 mm 2 to 18 mm 2 , and the invention section of the patent application scope of the present invention is further Regarding the rice cooker of the first application of the patent scope, a filter is detachably attached to the lower portion of the pressure valve 316828 9 1268768. (Effects of the Invention) According to the invention described in the first to third aspects of the patent application, after the end of the cooking step of the hot enthalpy of cooking, the stalk is maintained after the pin is held at the solid pressure. The step further performs the heat retaining step, and by opening the pressure enthalpy in the step of holding the fern, the pressure in the pot is sharply lowered to give the rice granules, so that the rice grains located at the central portion of the steel and the central portion of the inner side wall are located. The rice grains are wet to each other, & m ^ , 'the same σ, and the rice grains can be uniformly heated and the rice is evenly distributed. In particular, when the pressure valve is opened, heating is performed when the pressure in the pot is lowered, and H is used to rapidly and violently reduce the pressure inside the steel, and the large towel field is stirred and uniformly heated in the pot. The entire rice grain, and the upper part of the object after the second solution, forming a hole of a predetermined size, that is, the so-called "Steam Hole", is visually ancient and looks very delicious. tasty. Shen Zhu saw it. Look at Φ Guangli ^ ^ Open the pressure valve in the 'Furton maintenance step, and open it, but after the predetermined opening time, the reaction valve will be closed. Therefore, you can maintain the step at the same time. The pressure in the pot is maintained, and the rice is heated, so that the rice without the unheated portion can be cooked. Similarly, after the pressure is shut off „ ^ ^ to solid (9)..., the 'cooked food is heated until it is pressurized ^ . At ^ ^ v Dan ° Hai [forces the predetermined time, so it can be filled by pressure and heat month b The heating of the rice granules is made up of 4 straight 41 » so that the center part of the undiluted # points can also be softened. It is according to the patent scope 筮" The inventions described in ang. 4 and 5 are in boiling 316828 1268768. When the pressure valve is not opened, the pressure in the pot is kept to read'. Therefore, by setting the pressure in the pot to this range, the rice can be more intensely cultivated by a true appearance (Canine Buddha). - Boil the rice balls while mixing them. That is, the pressure in the pot in this range is sufficient to be stirred experimentally, ^ with the lowest pressure value of the pressure risotto and the pressure change due to the intense pressure change, so that the simmered material is not ejected out of the pin. The maximum pressure » ^ ° ... after the 'maintaining the pressure of the step _ open time, is set to the time when the pressure inside the pin is reduced to atmospheric pressure or close to atmospheric pressure, so when the safety valve is closed and open The pressure difference in the pin is extremely large, and the pressure difference is large, so that the rice grains flow in the pot and are thoroughly mixed and stirred, and more uniformly heated. According to the invention described in the sixth aspect of the invention, since the number of opening and closing of the pressure valve in the holding step is set to i to 1 time, if the amount of remaining water in the steel is sufficient, the number of times may be increased. Increase and increase the effect of the transfer, but since the amount of remaining water will decrease, it can also be set within the range of the number of times that can be charged. Further, when the number of opening and closing of the set pressure 为 is two or two times, a sufficient stirring effect cannot be obtained. According to the invention of the seventh aspect of the invention, the first opening operation of the pressure valve in the boiling maintaining step is set after the calculation of the predetermined time after the detection of the boiling of the boiling detection hand is completed, because Immediately after the test, the pressure valve is opened, but it is opened after the predetermined time of boiling from the steady state, so it can be surely fixed in the zigzag 316828 11 1268768 evil 'jn -- the pressure is reduced, and can be easily The first pressure 4 is open ^ ' to obtain a stable mixing effect. In the calculation of the predetermined time, the invention is started when the amount of glutinous rice is large, and the amount of rice is less than the "small". At the end of the calculation = 1 or before the end of the calculation, the heating is started. Therefore, it is also possible to obtain a delicious and delicious rice course according to the heating amount at the time of boiling according to the 炊 必. When the pressure valve is opened, the simmered material must be heated. The pressure can be lowered in one breath to achieve a mixing effect. According to the invention's internal pressure as recited in claim 9, the ball is separated from the pressure hole, and the wire (four) force is released from the air to the atmosphere, and the opening area of the larger force hole is set to shorten the pressure valve. Open time, and set the pressure inside the pot with a large pressure, so that when the pressure valve is opened, the high pressure in the pot is released from the pressure hole with a large opening area, #压压孔The larger opening area and the multiplication effect of the heating of the cooking material at the opening of the pressure valve can achieve high efficiency mixing and mixing. According to the invention of claim 10, by setting the opening area of the pressure hole to be in the range of 6_2 to 18 mm2, the pressure of steel = 5 can be smoothly performed. If this area is increased, the pressure can be released quickly, but if the area is too large, it may cause danger and go to the outside. Therefore, it is preferable to set the above range. According to the invention described in claim 11, the filter is provided in the lower portion of the pressure valve, and the filter 316828 12 1268768 can be used to prevent the rapid flow of rice grains in the pot when the pressure valve is opened.

In this cooking step, with the closing of the pressure valve (14), the steel bottom (correction) temperature and the vapor temperature are raised by the heating at the maximum power, and the pressure in the pot is rapidly increased to 丨·2 Air pressure. Thereafter, once the vapor sensing profit (19a) detects that the boiling temperature (large) of the cooked material reaches π degrees (the bottom temperature detected by the temperature sensor (19b) is 〇 5 degrees) (S10 to S11) ' Then, as shown in Fig. 8, the process proceeds to the boiling maintaining step to maintain the pressure in the steel at a pressure of 1.2 gas (S12 to S13). The i 2 gas pressure described herein is the pressure for obtaining the best result in the test, but the pressure in the pin is not limited to the pressure of 1.2 gas, and the essence can be obtained even in the range of, for example, the pressure of 1.1 to L 4 . It has the same good effect as the case of 1 · 2 air pressure. Here, the operation in the boiling maintenance + step will be described in more detail with reference to Figs. 8 and 9 . When the steam sensor (19a) detects the boiling temperature ((κ) = 75 degrees, the IH power of the heating means (4) is set to "〇" (refer to 316828 18 1268768, Fig. 9) (S14) ), and the first timer (22) starts the calculation of the predetermined time (tl = 12 seconds) (S16), and the second timer (23) adds the opening time (T) of the pressure valve (14) (4 seconds) The time (t2 = 16 seconds) is set to the predetermined time of the first timer (22). That is, the second timer (2 3) starts counting 16 seconds while the first timer (2 2 ) The calculation is performed for 12 seconds (S17 to S18) after the start of the second timer (23). / In addition, both the second timer (23) and the second timer (23) are used to set the opening and closing period of the pressure valve (14). The third timer (24) is set to 32 seconds (S19). - As a result, after the vapor sensor (19a) detects the boiling temperature, the 1st and the 疋 are exactly (22) and the difference is 12 seconds. The pressure valve (14) is turned off, and after the calculation of 12 seconds, the link (17a) is operated, and the pressure valve (4) is opened for 4 seconds between the opening days π (refer to Fig. 8 and Fig. 9). As described above, the pressure in the pot is maintained at 沸.2 at the boiling detection time point, and the pressure is maintained between 12 seconds after the boiling detection. Once the 12 seconds have elapsed, the pressure valve is opened ((4) 4 seconds, and The two-force release of the steel force is heated by the heating means (4) at the time of the opening of the pressure valve (丨4) at the time point after the above 12 seconds, so that the steel (2) can be stirred more vigorously. The cooking time of the heating means (4) when the pressure valve (14) is opened is explained in more detail in Fig. 5 to Fig. 7 of the photo. According to the therapeutic gas sensor (19a) At the time of the Foton detection, the amount of heating (heating time "Q)) in the step of maintaining the Foton is set in accordance with the amount of rice. (S20). The setting of the heating time (tQ) is based on the 316828 19 1268768 in the cooking step. The amount of glutinous rice is determined to be poor, and the heating (4) (tQa) is exempted from being longer when the amount of glutinous rice is "large", and the heating time (Qb) when the glutinous rice is in the factory. For moderate levels, the heating time (t Q c) when the amount of risotto is "small" is set to be shorter. The fourth benefit (25) is calculated from the set time of the second timer (23) calculated from the boiling detection of the vapor sensor (丨9a). 6 • Seconds, minus the above The time after the heating time (tQ) (t4 = 3 to 9 seconds) Lu ^ 21), after the amount of glutinous rice is "Da" Riji, after the calculation of the predetermined enthalpy after boiling detection, (t4a = 3 seconds), heating is performed. When the amount of glutinous rice is "medium", the heating is performed after the predetermined time (t4b = 6 seconds) after the tampering test, and the aging time is displayed, and the defensive time is determined by the predetermined time after the differential boiling detection (Mczg). After 2 seconds), heat is applied. Next, referring to the glutinous rice amount data (S22), when the glutinous rice meal amount is "medium", the fourth timer (25) which is calculated after the tampering detection is performed for 6 seconds (S23 to S25). The pressure valve (14) is closed between this and the heating of the slamming means (4) is stopped. When the fourth timer (25) has been counted for 6 seconds (S26), the heating means (4) is operated at the maximum power, and heating in the heating time (sin = ι sec) is performed (S27 to S28). Here, the time point after the calculation of the heating time (tQb) coincides with the time point between the 12 seconds of the first time crying (22) (S29). "The calculated output of the first timer (22) not only starts the calculation between the decompression timer (26) and 4 seconds, but also moves the connecting rod (17 &) and moves the ball (11) from the pressure. The hole (9) separates and opens the pressure valve (14) 夕 316828 20 1268768 · ' (S31). Since the opening time of the pressure 阙 (14) is shorter than the 10 seconds between (tQb), the pressure valve (14) At the time of opening, the heating means (4) is heated at the maximum power, and then the pressure in the pot is rapidly lowered to the air pressure by opening the pressure valve (14) for 4 seconds (S32). At this time, at the pressure valve 04 At the time of opening, the cooked material is heated at maximum power, so that the cooked material in the pot (2) can be stirred more vigorously - that is, due to the opening time between the pressure valve 〇 4) and 4 seconds The heating of the maximum pressure of the heating means (4) of the Lu pressure valve (14) is reduced, and the pressure is rapidly reduced from 1 to 2 to 1 Torr, and the rice grains and water in the pot generate a great flow. That is, intense agitation is performed. Of course, the opening area of the pressure hole (9) at this time is also set to promote the impatience. The force is reduced, and the opening area (4) and the opening time of the pressure valve (T=4 seconds) and the pressure in the pot (P) are set such that the larger (p) is, the larger the setting (a) is, and the opening time (T) is set.俾The steam (moisture) in the pot is not discharged to the outside air. ❿ (4) If the time (Τ) is extremely short, for example, about 2 seconds, it cannot be reduced from 1.2 to 1 @〇〇 In addition, if the opening time (1) is extremely long, for example, 5 seconds or more, the pressure drop can be rapidly reduced. However, since a large amount of steam (moisture) in the pot is released, it is impossible to ensure a plurality of pressure reductions. The amount of water in the pot is required. Therefore, the opening time (1) = 4 seconds of the present embodiment is based on the experimental results, and is applied to maintain the steel in addition to increasing the opening area (1) of the pressure hole (9). When the internal pressure is h2 air pressure, the pressure valve (14) is opened and the pressure is reduced rapidly, and the pressure is reduced by 316828 / 1268768 and the maintenance of 1.2 gas is repeated up to 1 time. Pressure: (9) The opening area (4) is preferably 6_2 to 18_2 two pressure holes ( 9) The diameter is about I-) and the value is attached to the value. Right 0 is also the area of the woman, seeing the .e heart can quickly release the pressure in one breath, ^ too large area may lead to danger and moisture It flows quickly to the outside, so this value is ideal. In addition, the number of opening and closing between the pressures is ideal. This is because the remaining water in the right pot is filled with the effect of scrambling, but even if the number of times = = If the increase is sufficient, it will also produce the mixing. It can be 4 2;; = if the remaining water volume is turned on and off. _ The material (4) The maximum pressure of the remaining water is 5 m Dan. After the opening time (1) = 4 seconds (s33), the S35 is closed. The power of the second heating means (4) is "〇" (S34 to coffee), and the pressure in the pot is again increased by the residual heat in the steel. One: = In the pot [When the force rises, the 4th timer () starts to calculate, = = "Medium" time (·6 seconds), then I Si; force, between (10), seconds) · Close The opening and closing of the pressure valve (4) of the pressure valve (S36), then at the "maximum power", and the - side force Λ 1) < between the heating means to achieve the temperature of sl 7 while maintaining the boiling state, the bottom temperature When the temperature reaches 130 degrees, the cooking step is carried out. The cooking step 1 is performed while the last name z is in the state, and the net X is performed while the bottom (in the pin) temperature is a relatively high door cooking step (S37). 316828 22 1268768 After the completion of the cooking step 1, the process proceeds to an additional cooking step of heating the cooked material for a long period of time by removing the excess moisture by heating means (S38). When the above-described additional cooking step is completed, the process proceeds to a step of cooking (^39) by a temperature slightly lower than the temperature in the pot of the cooking step 1 described above. After μ, the process moves to the incubation step and ends the series of risotto steps (). In the above (S22), when the rice meal amount data is "large", the flow moves down to (S41), and the fourth timer (25) which is calculated after the boiling detection is calculated for 3 seconds (S42), ( S43). In between, the pressure valve (14) is closed by Je and is not heated. Once the fourth timer (25) has been calculated for 3 seconds (S44), heating is performed according to the maximum power of the heating means (4), and heating is performed for the heating time (tQa = 13 seconds) (S45 to S46). ^Between the calculations (tQa=13 seconds), the heating is performed according to the heating of the hand 4, and the heating start time point is the stage before the calculation according to the 12th second of the first timer (2 2 ). It is used to fully heat the amount of the cooked material and is provided when the pressure valve (14) is opened. Then, the same operation as the case where the above-mentioned risotto amount is "medium" is performed. When the risotto data is "small" (S47), the fourth timer (25) calculated at the boiling detection f is calculated as "(four) seconds) (S48 to S49). In between, the pressure valve (14) is turned off and is not heated. Once the fourth timer (25) is calculated (t4c=M>,) (S5〇), 316828 23 1268768 performs heating according to the maximum power of the heating means (4), and Heating (tQc=7 seconds) is performed (S51 to S52). The same operation as described above is performed. As described above, the present invention is carried out after the end of the cooking step of the rapid heating of the cooked material. Maintaining the boiling step of the fixed pressure and holding the heat retaining step, and by opening the pressure valve in the boiling maintaining step, the pressure in the pot is sharply lowered to stir the rice grains, so that the rice grains located at the central portion of the pot and the inner side wall are The rice grains are stirred and mixed with each other, and the whole rice grains can be uniformly heated and the uniform rice is cooked. ... Especially when the pressure valve is opened, the cooked material is heated while the pressure in the pot is lowered, thereby further greatly (4) within the pin Rice grains, so that the whole rice grains in the pot can be heated in a sentence to form a hole of a predetermined size on the top of the boiled cooked material, that is, the so-called "crab hole" of the vapor-penetrating hole (steamH〇le) ) 'a visually sloppy, looks very delicious. In addition, the pressure valve is opened during the boiling maintenance step, and is opened, the force is ...m cook 16 ❻疋 After the preset opening time, the pressure valve is closed. Therefore, it is possible to maintain the pressure in the pot while maintaining the temper in the spleen, and to sleep, and to maintain the constant pressure in the pot, and to continue the person; 4_ only heats up, so that the rice without the unripe portion can be cooked. = only: also [after the force valve is closed, heating the cooked material until it is added to a fixed pressure] and maintaining the force for a predetermined time, so it can be fully heated by repeated force and heat to privately ..., and the unripe portion The center of the department can also be softened. In addition, the pressure valve is maintained at the pressure of 316 々 々 々 々 々 、 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 316 The pressure is within the target circumference' and the stirring according to the sudden boiling is sufficiently performed. In the yoke case only, the induction coil is used as the twisting means (4), and ^ is not limited to such a heating means, and may be a heating plate or other heating means. Further, regarding the fine opening structure, as long as it is a state in which the valve can be forcibly opened from the state in which the dust valve is closed, it is a mechanically acting mechanism or an electromagnetically acting mechanism.
