The following (Table 1) represents the experimental results for preventing the spilling of noodles, and represents the state when the noodles are charged and left at a constant heating power after boiling. However, the precondition that the amount of water is within 60% of the height of the pan and the ratio of the amount of noodles to the amount of water is 1 liter of water per 100 g of noodles.

  In the first condition, 100 g of noodles, 1 liter of water, a pot of φ16 cm with a heating power of 1600 Kcal / h, in the second condition of 300 g of noodles, 3 liters of water, a pot of φ22 cm, with a heating power of 1600 Kcal / h, in the third condition Dry noodles, elementary noodles, spaghetti, dried soba noodles, and raw udon were tested in 300 g noodles, 3 liters of water, and a hot pot of 2800 Kcal / h, respectively. Falling temperature represents the degree of decrease in hot water temperature when noodles are added, blowing up is the time from when noodles are introduced until bubbles start to appear, and spillage indicates the time from when noodles are introduced until spilling begins Yes.

  According to the experimental results, for example, in the case of dry udon under the first condition, when noodles are added, the temperature drop is 3 ° C., the blow-up time is 89 seconds, and no spillage occurs.

  Similarly, dry buckwheat under the first condition has a falling temperature of 3 ° C. when noodles are added, a blow-up time of 58 seconds, and a blow-off time of 68 seconds.

  For these reasons, noodles that are easily spilled even with the same dry noodles, and noodles that are not so, and of course, the state of spillage varies depending on the relationship between the amount and the thermal power.

  Naturally, raw noodles need to be strong because the thermal power of dry noodles is insufficient.

  FIG. 10 is a schematic explanatory view of the blow-up prevention mode of the present invention, and shows an outline of performing the thermal power control along the cooking pattern.

  The vertical axis represents the state of the temperature sensor (correlated to the hot water temperature) and the thermal power state, and the horizontal axis represents the passage of time. The hot water temperature rises by ignition. Before reaching the boiling point, the amount of hot water is determined from the temperature rise gradient, the boiling time, etc., boiling is determined by the boiling detection determining means, the thermal power after boiling is changed according to the amount of hot water, and the noodle charging is waited. When the noodle charging is started, the hot water temperature decreases according to the type of noodles. Depending on the descending temperature and the descending state, the thermal power is changed thereafter, and the thermal power control is performed so that it does not spill and is deliciously boiled.In particular, the thermal power of the first half is weaker than that of the second half. The thermal power changes frequently, and in the second half, the thermal power changes less, and the thermal power is increased to control it with a firewood. The above is the outline sequence of the spill prevention mode.

FIG. 11 shows a flowchart in the case where the cooking mode setting means is set to the spill prevention mode. After ignition, 100 is determined to boil, 101 is notified by boiling, etc.
2. After that, the thermal power control for preventing spillage is performed 103, and then manual fire extinguishing 104 is performed. The blowout prevention thermal power control 103 will be described later. By selecting the spill prevention key, it is possible to boil the noodles without causing them to spill.

  In the following, the same processes are denoted by the same numbers, and the description thereof is omitted.

  FIG. 12 shows a flowchart when the cooking mode setting means is set to the spill prevention mode, and the detailed setting of the spill prevention mode is selected between the dry noodle mode and the raw noodle mode. It is determined whether there is raw noodle key input 105. If there is a key input, thermal power control 103-1 for preventing raw noodle spilling is performed, and otherwise, thermal power control 103-2 for preventing dry noodle spilling is performed. By providing two kinds of selection keys to the boiled food key, especially dry noodles can increase the heating power compared to raw noodles and finish the boiled state well, but conversely when dry noodles are boiled with the heating power of raw noodles The result is a spill. Therefore, in the case of only one mode, the thermal power needs to be set slightly weaker for raw noodles in accordance with the dry noodle mode.

  FIG. 13 shows a flow chart for setting the hot water boiling mode in the cooking mode setting means and setting the blowout prevention mode when the fire extinguishing and reigniting operations are performed within a predetermined time after boiling. It is discriminated 106, and in that case, the fire is automatically extinguished 107. If not, it is determined whether there is a fire extinguishing operation 108, and if there is a fire extinguishing operation, it is determined 109 if 20 seconds have passed after the fire extinguishing. If so, the microcomputer is turned off 110. If not, it is determined whether or not there is a reignition operation 111. If there is a reignition operation, thermal power control for blowout prevention is performed 103, and then the fire is extinguished by manual operation 104. By performing the fire extinguishing reignition operation after boiling in the water heater mode, it is possible to use the spill prevention mode, so there are fewer cooking mode setting keys, and even if functions are added as a result, the appearance can be simple and summarized . Also, fewer cooking mode setting keys are required.

  FIG. 14 shows a flowchart in which the boiling mode is set by the cooking mode setting means and the spill prevention mode is entered when the sensor temperature falls within a predetermined time after boiling. It is determined whether or not there is a temperature sensor temperature decrease due to 112, and if so, thermal power control for preventing spillage is performed 103.

  By performing the operation to add noodles after boiling in the water heater mode, it can be in a spill-proof mode, so there are fewer cooking mode setting keys, so even if functions are added, the appearance can be simple and summarized is there. Also, fewer cooking mode setting keys are required.

  FIG. 15 is a flowchart showing the spill prevention mode when the boiling mode is set by the cooking mode setting means and the spill prevention mode setting button is operated within a predetermined time after boiling. After the boiling notification 102, the spill prevention is shown. It is determined whether there is a key input 113, and if so, thermal power control for preventing spillage is performed 103.

  Key entry with the spill prevention key after boiling makes it possible to determine when to switch to the spill prevention fire power even when there is no sensor drop when inputting noodles such as dry noodles, making it possible to make the rise more delicious with boil It is.

  FIGS. 16 and 17 show a flowchart for operating the spill prevention timer that is activated at a time earlier than the forgetting-off timer only when the spill prevention mode is set. It is determined whether or not 20 minutes have passed after boiling. If fired, 109 is automatically extinguished.

  By providing a dedicated forget-to-extinguish timer that operates after boiling and automatically extinguishes in 20 minutes, the time required for boiled items is usually up to 15 minutes, and even if you forget it, you can save energy with little loss.

  FIG. 18 shows a flow chart in which a cooking timer capable of setting the cooking time is provided, and when the spill mode is determined or when the spill prevention mode is set in advance, the cooking timer is started after boiling and the fire is automatically extinguished when a predetermined time elapses. After the boiling notification 102, if there is a cooking timer input 116, the cooking timer starts counting down 117. If the remaining time of the cooking timer runs out, 118 is automatically extinguished 109. For boiled items such as spaghetti, which require a relatively long time, the cooking timer can be heated only for the set time, improving convenience.

  19 to 21 are provided with a water amount discriminating means for discriminating the amount of water from the temperature rise gradient, the required time between predetermined temperatures, etc. during boiling with a constant heating power, and after boiling according to the water amount discriminated by the water amount discriminating means. If there is a thermal power control that changes the predetermined calorie, the reciprocating predetermined time, or both, and the temperature sensor has a descending slope within a predetermined time after boiling, the thermal power control is performed according to the descending slope. This is a flow chart of a spill prevention mode in which thermal power control is performed to vary predetermined calories, reciprocal predetermined time, or both. Ignition is set to 100, the thermal power is set to a constant thermal power of 2800 Kcal / h, 118, 50 ° C. to 95 ° C. 119, the boiling time is determined 120, the boiling is notified 121, and the thermal power is changed to 1200 Kcal / h 122. After that, it is determined whether or not 2 minutes have elapsed, and when it has elapsed, the heating power is reset to 400 Kcal / h 124, and after that, it is determined whether or not another 3 minutes have elapsed 125.

  If 2 minutes have not elapsed 123, it is determined whether there is a fire extinguishing operation 127, if the fire is extinguished, the sensor temperature is measured four times and the average value is substituted for FK1 128. It is determined whether 20 seconds have elapsed 129, if it has elapsed Turns off the microcomputer 130 to save power. In the range of 20 seconds, it is determined whether there is a reignition operation 129, and if there is reignition, if the time required to increase from 50 ° C to 95 ° C is 240 seconds or more 132, the water amount is 3 liters 133 .

  Similarly, when the time is longer than 190 seconds, 134 is set to 2 liters of 135, similarly when the time is longer than 115 seconds, 136 is set to 137, and when the time is less than 115 seconds, the water amount is set to 0.5 liters. When the water amount is 3 liters or 0.5 liter after completion of the above water amount determination, the thermal power is set to 2800 Kcal / h 140, otherwise the thermal power is set to 1600 Kcal / h 141. Thereafter, the sensor temperature is measured four times, and the average value is substituted into FK2.

  Substitute the lower temperature of FK1 and FK2 for FK 143 and start counter TIMEC = TIMEC + 1 144. If 8 times of data are accumulated, 145, find the minimum value of 8 times of data and substitute for Xmin 146. Subsequently, a sum total of values smaller than the value of FK is obtained from the eight times of data, and is assigned to SUMX 147. The SUMX × Xmin is calculated and assigned 148 to the array variable of B (I). The value of the first capture is in B (0).

It is determined whether or not 30 seconds have elapsed after reignition, 149, if so, 150 if the amount of water is 3 liters or 0.5 liter, and if the value of B (0) is 150 or more, the number of times since reignition (TIMEC = It is determined whether or not 10) is 10 times or more 152, and if not, the counter of the array variable is incremented by I = I + 1 and 159, and the process returns to the counter 144 of counter TIMEEC = TIMEC + 1. If so, it is determined whether B (0) <B (1) is 153. If so, it is determined whether B (1) <B (2) is 154. If so, the amount of water is 0.5. 1 for liters
54-1. When 50 seconds have elapsed after re-ignition, it is determined 158 to the 3 liter dry noodle mode. Otherwise, it is determined 157 to the 3 liter raw noodle mode.

  If the amount of water is not 3 liters or 0.5 liter, 150 is determined whether the amount of water is 2 liters 161, if so, BB = 150 is substituted 162, otherwise BB = 90 is substituted 163. If the value of B (0) is compared with BB and B (0)> BB, the 165 water volume is set to 165 and 2 liter raw noodle mode if it is 2 liters. To decide 167. The value of B (0) is compared with BB, and if B (0)> BB is not satisfied, it is determined if 164, TIMEC <HTIME is determined 168, and if so, it is determined whether the sensor temperature has decreased to 2 ° C. or less from FK. If this is the first time it has been lowered, 170 is substituted as HTIME = TIMEC + 10 171. If the sensor temperature does not decrease, the process goes to 159 where I = I + 1. It is determined whether TIMEC <HTIME is 168, otherwise, it is determined whether the amount of water is 3 liters 172, and if so, it is determined to be 3 liter dry noodle mode 173. If not, it is determined 174 whether the amount of water is 2 liters, and if so, it is determined 175 to the 2 liter dry noodle mode. If not, it is determined 176 whether the amount of water is 1 liter, and if so, 1 liter dry noodle mode is determined 177. Otherwise, it is determined 178 for the 3 liter dry noodle mode. After the mode is determined, mode combustion 179 is performed in accordance with the mode, and it is determined whether 20 minutes have elapsed after reignition 180, and if so, automatic extinguishing 181 is performed.

Similarly, FIG. 23 is a thermal power control for preventing spillage in the 1 liter dry noodle mode, FIG. 24 is a thermal power control for preventing spillage in the 2 liter dry noodle mode, FIG. 25 is a thermal power control for preventing spillage in the 3 liter raw noodle mode, and FIG. 25 shows thermal power control for preventing spillage in 1 liter raw noodle mode, FIG. 25 shows thermal power control for preventing spillage in 2 liter raw noodle mode, raw noodles have stronger thermal power than dry noodles, and the more water there is, the stronger the thermal power, In addition, the first half of the stroke time is conservative with the thermal power, and the second half is controlled with the thermal power suitable for boiling.

  FIG. 28 shows an example of a schematic flow of the drive determination means 31, and it is determined whether the sensor temperature is normal (sensor disconnection, short circuit, etc.) 67. If abnormal, go to an abnormal processing route 68 described later. It is determined whether the counter electromotive force is normal 69. If abnormal, it goes to an abnormality processing route 68, which will be described later. If normal, it is determined whether ignition is the first ignition 70. If it is not a position, an output to make it a “strong heating power position” is output 72.

  If it is not the first time, it is determined 70. If it is not the first time, it is determined from the previous stage whether there is a change in the heating power 73, if yes, it is determined whether the current heating power is different from the changed heating power 74. 75, if yes, output 76 to “strong thermal power position”, otherwise determine whether the modified thermal power is medium thermal power 77, otherwise output 78 to output medium thermal power position, otherwise low thermal power Output to position 79.

  It is determined whether any of the above output states is the heating power UP direction. If the direction is UP, the low speed movement 81 is set. If not, the medium speed movement 82 is set. Confirm 84 and return.

If it has not reached, it is determined whether the elapsed time has passed X seconds 85, and if it has elapsed, the process goes to the abnormality processing route 68. In the abnormality processing route 68, the safety valve output is turned OFF 86, the notification means is turned ON 87, and the process is ended 88.

  As described above, the heating power can be surely adjusted to the target heating power position, and when the heating power is increased from weak to strong, the heating power can be slowly increased. Here, as means for confirming 84 whether or not the target position has been reached, position discrimination means is provided, which will be described later.

  FIG. 29 shows another example of the schematic flow of the drive determination means 31. The same contents as those in FIG.

  It is determined whether the ignition is the first time 70, and if it is the first time, it is determined whether the electric drive device is not at the central stop position 89, and if not, the central stop position output is turned on 90, the operation goes to the electric timer ON 91 to determine whether the central stop position is reached 92 If not, it is determined whether X seconds have elapsed, and if it has elapsed, the process goes to the abnormality processing route 68.

  It is determined whether or not the target position has been reached by changing the normal heating power 84. If the target position has been reached, the process goes to the central stop position output ON 90. Whether it is the first time is determined 94, and in the case of the first time, the central stop position output is turned ON 90. If it is not the first time, go to the abnormality processing route 68.

  As described above, in this case, in addition to the operation of FIG. 11, the electric drive device is always returned to the central stop position after the heating power is changed. Further, when the electric drive device does not reach the target thermal power position due to some trouble, the electric drive device is returned to the central stop position, and manual thermal power adjustment is enabled as will be described later.
