Description

  The present invention relates to a cooking device such as a gas stove.

  In a cooking device such as a gas stove, the temperature of the cooking container heated by a heating means such as a burner is detected by a temperature sensor, and the operation of the heating means is controlled while monitoring the detected temperature, whereby cooking in boiled dishes is performed. A device having a function of preventing burning of an object has been conventionally known.

  For example, in the cooking device (gas stove) found in Patent Documents 1 and 2, basically, the detected temperature of the cooking container has reached the equilibrium temperature (the temperature at which the detected temperature is kept constant or substantially constant). In some cases, it is judged that boiled food is being served. In this case, when the detected temperature of the cooking container rises to a temperature higher than the equilibrium temperature by a predetermined temperature (hereinafter, sometimes referred to as a non-burning temperature), the burner is extinguished, or the By reducing the amount of combustion of the burner, the cooked product is prevented from being burnt.

In addition, the technique found in Patent Document 2 also describes a technique for preventing the non-burning function for stewed dishes from working when steamed dishes such as grilled gyoza dishes and fried noodle dishes are performed. In this technique, based on the pattern of change over time of the detected temperature of the cooking container, it is determined separately from cooked food whether or not the food being cooked is steamed. If it is determined that the dish being cooked is a steamed dish, the detection temperature of the cooking container does not depend on the equilibrium temperature without operating the non-burning function for boiled dishes (the non-burning prevention function). When the temperature rises to a temperature sufficiently higher than the temperature, the burner is extinguished. Furthermore, in the technique shown in Patent Document 2, when the detected temperature rises relatively rapidly after the detected temperature of the cooking container reaches the equilibrium temperature, the user intentionally lifts the cooking container temporarily. I am trying to judge. In this case, as in the case of steamed baked dishes, the detected temperature of the cooking container is not dependent on the equilibrium temperature without operating the anti-burn function for boiled dishes (sufficiently higher than the non-stick temperature). When the temperature rises to a high temperature, the burner is extinguished.

  By the way, the burning of cooked foods does not always occur at the same temperature and in the same way. Generally, the temperature of the cooking container where the burning occurs due to various factors such as the amount of cooking and the cooking method. Or the degree of scoring that occurs. In addition, even if the contents of cooking are the same, the degree of burnt food allowed for the user or the degree of burnt food preferred for the user generally varies from user to user.

  On the other hand, in the conventional cooking device as seen in Patent Documents 1 and 2, conditions for making the non-sticking function for cooking boiled food work are uniformly set in advance. For this reason, depending on the amount of cooking, the cooking method, etc., it is acceptable for the user, or the burning of the cooking proceeds more than the preferred degree of burning, or the cooking is not burning, but the cooking is in progress. In some cases, the operation of the heating cooker automatically stops.

  In addition, in the technique found in Patent Document 2, when it is determined that the dish being cooked in the cooking container is a steamed dish, or when the pot is being raised so that the cooking container is temporarily lifted, The burner is not automatically extinguished until the temperature detected by the temperature sensor rises to a temperature higher than the non-burning temperature of the normal non-burning function for cooking boiled food. For this reason, when there is little quantity of foodstuffs, there existed a problem that the burning of a cooking thing may advance rather than the degree of a burning preferable for a user.

  This invention is made | formed in view of this background, and it aims at providing the heating cooker which can perform the operation | movement for preventing a burning of cooked food etc. with a preferable form for a user.

In order to achieve this object, the heating cooker of the present invention has a heating source, temperature detecting means for detecting the temperature of the cooking container heated by the heating source, and the detected temperature of the cooking container by the temperature detecting means. After reaching the equilibrium temperature, when a predetermined necessary condition including at least a first condition that the temperature rises by a first predetermined temperature higher than the equilibrium temperature is satisfied, the operation of the heating source is stopped, Or, in a heating cooker provided with a control means having a function of executing a control process for preventing burning to reduce the calorific value of the heating source, the cooked food that can be operated by the user and is heated in the cooking container A non-burning prevention request level setting means for setting a non-burning prevention request level representing a degree of request for preventing non-burning to the control means in accordance with the operation of the user; Means a basic configuration that variably determines the first predetermined temperature in accordance with the set value of the anti required level scorching the by preventing the required level setting means with focal down.

According to such a basic configuration , the user sets the required level of non-sticking to the control means by operating the non-stick required level setting means, thereby increasing the required degree of preventing the food from being burnt. The control means can be instructed. The degree of demand for preventing scorching is higher, the lower the degree of scorching of the food allowed for the user (the permissible degree of scoring), and the higher the certainty of preventing scorching of the food. It means that sex is required.

  Then, the control means, according to the burn prevention request level set by the user, and eventually according to the degree of request for preventing burn (hereinafter, sometimes referred to as a burn prevention request level). The predetermined temperature is variably determined. In this case, as the first predetermined temperature is higher, the control means does not execute the burn prevention control process until the detected temperature of the cooking container rises from the equilibrium temperature to a higher temperature. There is a high possibility that cooking will be burnt. Therefore, when the first predetermined temperature is variably determined in accordance with the burn prevention request level, basically, the higher the degree of request for burn prevention represented by the burn prevention request level, the higher the first predetermined temperature. The first predetermined temperature may be set so as to reduce the temperature.

  In this way, the first predetermined temperature is variably determined according to the required level of non-burning so that when the detected temperature of the cooking container rises to a temperature suitable for the degree of burning of the food desired by the user, the burning is performed. The prevention control process can be executed to stop the operation of the heating source or to reduce the heat generation amount of the heating source.

Therefore, according to the said basic structure , the operation | movement (control processing for a non-sticking) for preventing a burnt thing etc. from being burned can be performed with a form preferable for a user.

The cooking device according to the present invention is a steamed grill that determines whether or not the dish being cooked in the cooking container is a steamed dish based on a pattern of change over time of the detected temperature of the cooking container in the basic configuration. Cooking judgment means, and first judgment means for judging the level of the demand level represented by the setting value of the non-burning prevention demand level, wherein the predetermined requirement is determined by the steamed dish judgment means by the cooking container. Or the second determination that the first determination means determines that the degree of request expressed by the set value of the non-stick prevention request level is high. In addition to the first condition, the condition is included (first invention) .

According to the first aspect of the invention, the control means includes the second condition in addition to the first condition as a necessary condition for executing the burn prevention control process. It is determined that the dish being cooked in the cooking container is a steamed dish, and the required degree (the required degree of non-burning prevention) represented by the set value of the non-burning prevention request level by the first determination unit. If it is determined that the value is low, the control means does not execute the burn prevention control process. Therefore, when it is preferable or acceptable for the user that the cooked product has some degree of burning, when the cooking performed in the cooking container is determined to be steamed cooking by the steamed cooking determination means, The control process for preventing the burning is not executed so that the operation of the heating source is not automatically stopped or the amount of heat generated by the heating source is not reduced before the cooking in the steamed dish is finished. Can do.

  On the other hand, even if it is determined that the cooking performed in the cooking container is a steamed baked dish by the steamed baked food determining means, if the degree of demand for the non-burning is high, that is, the burning does not occur as much as possible. When the user desires, the second condition, which is one of the necessary conditions for the control means to execute the burn prevention control process, is satisfied. For this reason, when the food being cooked in the cooking container is actually a simmered dish, but it is erroneously determined to be a steamed dish, the burning of the dish that is not desired by the user is prevented. It becomes possible.

  Therefore, not only in boiled dishes, but also in steamed dishes, it is preferable to cause the control means to execute the control process for preventing burnt or not to execute the control process for preventing burnt in a form preferable for the user. it can.

Further, in the basic configuration , the cooking container is lifted from a predetermined placement position with respect to the heating source based on a pattern of change with time of the detected temperature after the detected temperature of the cooking container reaches the equilibrium temperature. A cooking container lifting judgment means for judging whether or not the cooking container is lifted; and a second judgment means for judging the level of the degree of demand represented by a set value of the non-burning prevention demand level, wherein the control means comprises the cooking A condition that it is determined by the container lifting determination means that the cooking container is lifted, and the second determination means determines that the required degree represented by the set value of the non-sticking prevention request level is low. Is established, and the detected temperature of the cooking container rises from the equilibrium temperature to a temperature higher than the first predetermined temperature by a second predetermined temperature that is higher than the first predetermined temperature. A cooking container lifting support control process for stopping the operation of the heating source when the condition is satisfied, the predetermined requirement is determined by the cooking container lifting judgment means to lift the cooking container In addition to the first condition, the second condition is determined to be determined by the second determination means to be determined that the required degree represented by the non-burning prevention request level is high. It is not preferred.
Similarly, in the first aspect of the invention, the cooking container is placed at a predetermined placement position with respect to the heating source based on a pattern of change with time of the detected temperature after the detected temperature of the cooking container reaches the equilibrium temperature. Cooking container lifting judgment means for judging whether or not it is lifted from, and second judgment means for judging the level of the degree of demand represented by the setting value of the non-burning prevention demand level, the control means, The cooking container lifting determination means determines that the cooking container is being lifted, and the second determination means determines that the required degree represented by the set value of the non-burning prevention request level is low. And the detected temperature of the cooking vessel rises from the equilibrium temperature to a temperature that is higher than the first predetermined temperature by a second predetermined temperature. A function to execute a cooking container lifting support control process for stopping the operation of the heating source when the condition is satisfied, and the predetermined necessary condition is determined by the cooking container lifting judgment means. Or the third condition that the second determination means determines that the required degree represented by the non-burning prevention request level is high. It is preferable to include the other (second invention).

According to this second invention , it is determined by the cooking container lifting judgment means that the cooking container is being lifted, and the second judgment means is represented by the set value of the burn prevention request level. The condition that it is determined that the required degree (the required degree of burn prevention) is low, and the detected temperature of the cooking container is higher than the equilibrium temperature by a second predetermined temperature that is higher than the first predetermined temperature. When the condition of rising is established, a control process for lifting the cooking container to stop the operation of the heating source is executed by the control means. Therefore, the user temporarily lifted the cooking container for the purpose of moving the food in the cooking container in a situation where it is preferable or acceptable for the user to cause a certain degree of burning of the cooking. In the case (so-called pan-up), the control means until the detected temperature of the cooking container rises above the equilibrium temperature by a second predetermined temperature higher than the first predetermined temperature. The operation of the heating source will not be stopped. Therefore, it is possible to prevent the burned-out control process for stopping the operation of the heating source or reducing the calorific value of the heating source from being performed earlier than necessary and heating the food to be insufficient. .

  On the other hand, even when the cooking container lifting determination means determines that the cooking container is lifted, the user desires that the burning prevention is as high as possible, that is, the burning does not occur as much as possible. In this case, the third condition, which is one of the necessary conditions for the control means to execute the burn prevention control process, is satisfied. For this reason, it becomes possible to prevent the burning of the food which the user does not want to occur.

  Therefore, even in a situation where the user temporarily lifts the cooking container for the purpose of moving the cooked food after the temperature of the cooking container reaches the equilibrium temperature, the control process for preventing the burning in a preferable form for the user. Can be executed by the control means, or the non-burning control process can be prevented from being executed.

FIG. 4 is a flowchart showing a process for setting the burn-in prevention request level corresponding to each individual burner 4 to the control unit 50, and FIGS. 5 and 6 are control units at the time of cooking using any of the burners 4. It is a flowchart which shows the control processing which 50 performs.

  Here, before explaining the processing of FIG. 4 to FIG. 6, the outline of the operation of the heating cooker 1 of the present embodiment and the burn prevention request level will be described.

  In the heating cooker 1 of the present embodiment, the temperature of the cooking container W placed on the virtues 7 is detected by the temperature sensor 8 in contact with the cooking container W during cooking using each of the burners 4, and the detection is performed. A signal is input to the control unit 50. Then, the control unit 50 sequentially recognizes the temperature of the cooking container W based on the detection signal input from the temperature sensor 8. Hereinafter, the temperature of the cooking container W recognized by the detection signal of the temperature sensor 8 is referred to as a detected temperature TS.

  During normal cooking other than automatic cooking, the control unit 50 detects that the detected temperature TS of the cooking container W has reached the equilibrium temperature TH (the temperature in an equilibrium state where the detected temperature TS is kept substantially constant). Monitor whether or not. When the control unit 50 detects that the detected temperature TS has reached the equilibrium temperature TH, the control unit 50 basically regards the dish being cooked in the cooking container W as a boiled dish, and the cooked food. A control process for preventing burning is performed to prevent burning. In this control process for preventing burning, the control unit 50 detects that the detected temperature TS is higher than the equilibrium temperature TH by evaporation of moisture in the cooking container W after the detected temperature TS of the cooking container W reaches the equilibrium temperature TH. 1 When a predetermined necessary condition including at least a first condition that the temperature rises by a predetermined temperature or higher is satisfied, the combustion operation of the cooker 4 heating the cooking vessel W is stopped (the cooker 4 The fuel gas supply to is cut off to extinguish the burner 4).

  The burn-in prevention requirement level (hereinafter referred to as reference symbol Kx_lb) represents a degree of requirement for preventing the burn-in of the cooked food by the burn-in prevention control process. Here, the degree of requirement for preventing the burning of the cooked food (hereinafter, sometimes referred to as the degree of demand for burning prevention) increases the degree of the burning of the food allowed for the user (the degree of allowable burning). ) Is low, which means that a higher certainty of preventing the cook from being burnt is required.

  In the present embodiment, the burn prevention request level Kx_lb is set to five levels (integer values) from “1” to “5” by the operation of the operation panels 12 and 13 by the user for each combustor 4. It can be set. Then, the control unit 50 variably determines the first predetermined temperature in the first condition in accordance with the set value of the non-burning prevention request level Kx_lb (and in accordance with the degree of non-burning request), and the determination is made. The first predetermined temperature is used in the control process for preventing burning.

  In this case, in the present embodiment, the burn prevention request level Kx_lb means that the larger the set value is, the lower the degree of request for prevention of burn of the cooked food (in other words, the higher the allowable degree of burn is). Then, the control unit 50 basically sets the first predetermined temperature so as to increase the first predetermined temperature as the set value of the non-burning prevention request level Kx_lb is larger (the lower the degree of demand for non-burning prevention is). decide.

  Specifically, in the present embodiment, when the setting value of the non-burning requirement level Kx_lb is “3” or more (when Kx_lb = 3, 4 or 5), the first predetermined temperature is Kx_lb = In the case of 5, when Kx_lb = 4, and when Kx_lb = 3, respectively, for example, 50 ° C., 40 ° C., and 30 ° C. are determined. When the set value of the non-burning prevention request level Kx_lb is smaller than “3” (when Kx_lb = 1 or 2), the first predetermined temperature is the same as the first predetermined temperature when Kx_lb = 3. The temperature is determined (30 ° C. in this embodiment). In the present embodiment, the set value of the non-stick requirement level Kx_lb is not only used for determining the first predetermined temperature, but also included in the necessary conditions for executing the non-stick prevention control process. It is also used to determine whether a condition other than the first condition is satisfied.

  Based on what has been described above, the processes of FIGS. 4 to 6 will be described below. 4 to 6, each switch of the operation panels 12 and 13 is abbreviated as “SW”.

  The non-burning prevention request level Kx_lb corresponding to each of the stove burners 4 is set as shown in the flowchart of FIG. 4 when the cooking device 1 is in the operation stop state (fire extinguishing state of each cooker burner 4).

  That is, in the operation stop state of the heating cooker 1, the control unit 50 operates the up switch 20u of the common operation unit 15 of the right operation panel 12 and the up switch 25u of the left operation panel 13 to be simultaneously turned on for 3 seconds or more. It is monitored whether (push operation) has been performed (STEP 1).

  In this case, if the determination result in STEP 1 is affirmative when the user simultaneously turns ON the up switches 20 u and 25 u for 3 seconds or more, the operation mode of the processing of the control unit 50 sets the non-burning prevention request level Kx_lb. Is the operation mode.

  In this case, the control unit 50 first sets a predetermined default burner 4, for example, the right burner 4R, as the burn target 4 for setting the non-burning prevention request level Kx_lb (STEP 2). Hereinafter, the setting target combo burner 4 for the burn prevention request level Kx_lb is referred to as a setting target combo burner Kx. The setting target stove burner Kx is one of the left stove 4L, the rear stove 4B, and the right stove 4R.

  Next, the control unit 50 causes the timer time display unit 22 of the right operation panel 12 to display the set value of the non-burning request level Kx_lb currently stored and held with respect to the setting target combo burner Kx (STEP 3). Further, in STEP 3, the selected stove display unit 21 displays whether the current setting target stove burner Kx is one of the left stove 4L, the rear stove 4B, or the right stove 4R.

  Next, the control unit 50 monitors whether or not the up switch 20u or the down switch 20d of the right operation panel 12 is turned on (pressed) in STEPs 4 and 6.

  In this case, when the user wants to set the set value of the burn prevention request level Kx_lb to be larger than the current value (the value currently displayed on the timer time display unit 22), the user operates the up switch 20u to turn on the set value. Is to be made smaller than the current value, the down switch 20d is turned on.

  When the up switch 20u is turned on, the control unit 50 increases the set value of the non-burning prevention request level Kx_lb by “1” from the current value every time the ON switch is turned on (STEP 5). However, the upper limit value of Kx_lb is “5”, and when the set value of Kx_lb as the processing result of STEP 5 is larger than “5”, the set value of Kx_lb is maintained at the upper limit value “5”.

  Further, when the down switch 20d is turned on, the control unit 50 decreases the set value of the non-burning prevention request level Kx_lb by “1” from the current value for each ON operation (STEP 7). However, the lower limit value of Kx_lb is “1”, and when the set value of Kx_lb as the processing result of STEP 5 is smaller than “1”, the set value of Kx_lb is maintained at the lower limit value “1”.

  Then, the control unit 50 executes the process of STEP 3 following the process of STEP 5 or 7, and causes the timer time display unit 22 to display a new set value of Kx_lb.

  When the non-burning request level Kx_lb related to the setting target combo burner Kx is updated to a level desired by the user, or when the non-sticking request level Kx_lb related to the setting target combo burner Kx is already at the level desired by the user. In this situation, both the up switch 20u and the down switch 20d are not turned on, and the determination results in STEPs 4 and 6 are both negative.

  In this case, the control unit 50 further monitors whether or not the stove selection switch 19 of the right operation panel 12 has been turned on (pressed) (STEP 8).

  In this case, when the user intends to confirm or set the non-burning prevention request level Kx_lb for the stove burner 4 different from the current setting target stove burner Kx displayed on the selection stove display unit 21, the right operation panel By turning ON (pushing) the twelve stove selection switch 19, the setting target stove burner Kx is selected. At this time, each time the stove selector switch 19 is turned ON, the selected stove burner 4 is switched in order among the left stove 4L, the rear stove 4B, and the right stove 4R. The displayed burner 4 is switched.

  Then, the control unit 50 sets the stove burner 4 finally selected by the user by turning on the stove selection switch 19 as the setting target burner Kx (STEP 9), and repeats the processing from STEP 3 above. As a result, the non-burning prevention request level Kx_lb related to the setting target combo burner Kx newly set in STEP 9 is confirmed or updated.

  As described above, when the setting or confirmation of the burn-in prevention request level Kx_lb for one or more of the burners 4 is completed, the determination results of STEPs 4, 6, and 8 are all negative. At this time, the control unit 50 determines whether or not a switch other than the up switch 20u, the down switch 20d, and the stove selection switch 19 has been turned on (pressed) (STEP 10).

  In this case, if any switch other than the up switch 20u, the down switch 20d, and the stove selection switch 19 is not turned on in STEP 10, the process of the control unit 50 is in a state of waiting for the operation of one of the switches, and the process of STEP 3 is performed. Return to. Further, in STEP 10, when the switches other than the up switch 20u, the down switch 20d, and the stove selection switch 19 are turned ON, the processing of the operation mode for setting the non-burning prevention request level Kx_lb is ended, and the control unit 50 The process returns to the process of STEP1.

  By the above-described processing of FIG. 4, the operation mode of the processing of the control unit 50 by the specific operation using the up switch 20 u of the common operation unit 15 of the right operation panel 12 and the up switch 25 u of the left operation panel 13. Shifts to the operation mode for setting the non-burning prevention request level Kx_lb. In this operation mode, when the up switch 20u, the down switch 20d, and the stove selection switch 19 of the right operation panel 12 are turned ON, the user sets the non-burning prevention request level Kx_lb for each of the stove burners 4 to a desired level. It is possible to set or confirm the set value. In this case, the user increases the requirement level of the non-burning prevention level Kx_lb as the requirement level of the non-burning of the cooked food in the cooking using the stove burner 4 for setting the non-burning prevention requirement level Kx_lb increases. The value of Kx_lb is set so as to decrease the value.

  Note that the set value of the non-burning requirement level Kx_lb set as described above is stored and held in a writable non-volatile memory such as an EEPROM in the control unit 50.

  Next, the processing of the flowcharts of FIGS. 5 and 6 will be described. During normal cooking other than automatic cooking using any one of the stove burners 4, the control unit 50 executes the control process shown in FIGS. 5 and 6 for each of the stove burners 4. In the description of the control processing in FIGS. 5 and 6, it is assumed that cooking is performed using any one of the left stove 4L, the rear stove 4B, and the right stove 4R. The stove burner 4 (4L, 4B, or 4R) used in the above is denoted as the stove burner 4x. Then, the subscript “x” is added to the element corresponding to the conburner 4x. In this case, the subscript “x” means “L”, “B”, or “R”.

  The control unit 50 determines whether or not the ignition / fire extinguishing button 10x corresponding to the burner 4x is turned on (ignition operation in the fire extinguishing state of the burner 4x) (STEP 21). When the ignition / fire extinguishing button 10x is turned ON by the user and the determination result in STEP21 becomes affirmative, the control unit 50 starts timing by the first timer for timing, and also performs ignition processing of the stove burner 4x. Execute (STEP 22). The first timer is a timer that measures the time from when the combustor 4x is ignited (at the start of combustion operation). Hereinafter, the time measured by the first timer is referred to as elapsed time after starting. Further, in the ignition process of STEP 22, the control unit 50 opens the electromagnetic valve 34x and operates an igniter (not shown) while controlling the opening of the flow rate adjusting valve 35 to a predetermined opening for ignition. Then, the stove burner 4x is ignited.

  When the combustion operation of the stove burner 4x is started in this manner, the control unit 50 sequentially samples the detected temperature TS of the cooking vessel W placed on the five virtues 7x of the stove burner 4x, while detecting the detected temperature TS. Based on the time series, it is determined whether or not the temperature of the cooking container W has reached the equilibrium temperature TH (whether an equilibrium state of the temperature of the cooking container W has been detected) (STEP 23). This determination is performed as follows, for example. That is, the control unit 50 samples the detection signal of the temperature sensor 8x, for example, at intervals of 15 seconds, and samples sampling data TS (k), TS (k-1),. (k-6) is updated and stored every 15 seconds. TS (k) means the latest sampling data, and TS (k−n) (n = 1, 2,..., 6) means the sampling data 15 × n seconds before. Then, the control unit 50 uses the seven kinds of sampling data TS (k), TS (k-1),..., TS (k-6) for five types of change amounts of the detected temperature TS for 30 seconds. The absolute value of TS (ki) −TS (ki−2) (i = 0, 1,..., 5) is less than a predetermined amount (for example, 2 ° C. or less), and the change in the detected temperature TS for 90 seconds. When the absolute value of the quantity TS (k) -TS (k-6) is less than a predetermined quantity (for example, 5 ° C. or less), the temperature of the cooking vessel W heated by the stove burner 4x has reached the equilibrium temperature. Judge.

  Supplementally, any method other than the above can be used to determine whether the temperature of the cooking container W has reached the equilibrium temperature, as long as the method can determine whether or not the detected temperature TS is maintained substantially constant. You may make it perform using. For example, it may be determined whether or not the temperature of the cooking vessel W has reached the equilibrium temperature based on the distribution of sampling data of the detected temperature TS.

  When the temperature of the cooking container W reaches the equilibrium temperature and the determination result in STEP 23 becomes affirmative, the control unit 50 stores and holds the equilibrium temperature (STEP 24). In this case, in this embodiment, for example, the latest sampling data TS (k) value of the detected temperature TS is stored and held as the equilibrium temperature TH. For example, the average value of the detected temperatures TS within the latest predetermined time may be stored and held as the equilibrium temperature TH. The equilibrium temperature TH only needs to be representative or approximately indicative of the temperature of the cooking vessel W in the equilibrium state.

  Next, the control unit 50 determines whether or not the detected temperature TS of the cooking container W has risen to a temperature higher than the equilibrium temperature TH by a predetermined temperature ΔT1 (ΔT1 is, for example, 5 ° C. in this embodiment) (STEP 25). When this determination result is affirmative (TS ≧ TH + 5 ° C.), the control unit 50 starts counting by the second timer for timekeeping (STEP 26), and the detected temperature TS of the cooking container W becomes the equilibrium temperature TH. It is determined whether or not the temperature has increased by a predetermined temperature ΔT2 (in this embodiment, ΔT2 is, for example, 15 ° C.) (STEP 27). Then, when the determination result in STEP 27 becomes affirmative (when TS ≧ TH + 15 ° C.), the control unit 50 ends the time measurement of the second timer (STEP 28).

  Subsequently, the control unit 50 determines whether or not the detected temperature TS of the cooking container W has risen to a temperature higher than the equilibrium temperature TH by a predetermined temperature ΔT3 (in this embodiment, ΔT3 is 20 ° C., for example) (STEP 29). ). When this determination result is affirmative (TS ≧ TH + 20 ° C.), the control unit 50 starts counting by a third timer for timekeeping (STEP 30), and the detected temperature TS of the cooking container W is equal to the equilibrium temperature. It is determined whether or not the temperature has increased by a predetermined temperature ΔT4 (in this embodiment, ΔT4 is, for example, 30 ° C.) higher than TH (STEP 31). Then, when the determination result in STEP 31 becomes affirmative (when TS ≧ TH + 30 ° C.), the control unit 50 ends the time measurement of the third timer (STEP 32).

  After the detected temperature TS of the cooking container W reaches the equilibrium temperature TH by the processing of STEPs 25 to 32 described above, the time required to rise from TH + 5 ° C. to TH + 15 ° C., and the time taken to rise to TH + 20 ° C. The time required for the temperature to rise to TH + 30 ° C. is counted by the second timer and the third timer, respectively. Hereinafter, the time measured by the second timer is referred to as a second rising time after balancing, and the time counted by the third timer is referred to as a third rising time after balancing.

  Next, the control unit 50 executes the determination process of STEPs 33-35. The determination process of STEP33 and 34 is a process for determining whether the cooking currently performed with the cooking container W is a boiled dish based on the pattern of the time-dependent change of the detected temperature TS of the cooking container W. . The determination process of STEP 35 is a process for determining whether or not the degree of non-sticking request indicated by the non-sticking prevention request level Kx_lb set for the conburner 4x is high (the level of the degree of request).

  Here, when it is detected in STEP23 that the temperature of the cooking container W has reached the equilibrium temperature, the dish being cooked in the cooking container W is generally likely to be a boiled dish, There is also the possibility of steamed dishes such as grilled dumplings and yakisoba dishes. And when the said dish is a steamed baked dish, when the said control processing for non-sticking is performed similarly to a boiled dish, the stove burner 4x will be automatic in the stage where the cooking condition of a cooking item is insufficient. May be extinguished. Therefore, it may be preferable to include a condition that the dish being performed in the cooking container W is not a steamed dish as the necessary condition for executing the control process for preventing the burning.

  On the other hand, in the present embodiment, when the set value of the non-burning prevention request level Kx_lb set by the user is larger, the degree of request for prevention of burning of cooked food assumed by the user is lower (the allowable degree of burning is higher). Means higher). On the other hand, the smaller setting value of the non-burning prevention request level Kx_lb means that the required degree of prevention of burning of the cooked food assumed by the user is higher (the allowable degree of burning is lower). And when the degree of demand for prevention of burning of the cooked food assumed by the user is relatively high, it is possible to prevent burning of the cooked food regardless of whether the dish being cooked in the cooking container W is cooked food or steamed food. It is considered desirable to ensure that

  Therefore, in the present embodiment, as a necessary condition for the control unit 50 to execute the control process for preventing the burning, in addition to the first condition, the dish being performed in the cooking container W is a steamed dish, Alternatively, it includes a condition that the degree of requirement for non-sticking represented by the set value of the non-burning prevention requirement level Kx_lb is low (this corresponds to the second condition in the present invention).

  In this case, in the present embodiment, it is determined whether or not the cooking performed in the cooking container W is the steamed food by the judgment processing of STEP 33 and 34 among the determination processing of STEP 33 to 35 (possibility of steaming food). Whether or not is high). Therefore, in this embodiment, the process of STEPs 33 and 34 realizes the steamed dish determination means in the present invention.

  In this embodiment, this determination is made as follows. That is, paying attention to the time-varying pattern of the temperature of the cooking container W, in the case of steamed baked dishes such as grilled dumplings, the temperature of the cooking container W rises from the equilibrium temperature in many cases earlier than the boiled dishes. The temperature rise rate is faster than boiled dishes.

  Therefore, in the present embodiment, the control unit 50 determines whether or not the post-equilibrium third rise time, which is the final timekeeping time of the third timer, is shorter than a predetermined time TM1 (in this embodiment, TM1 is, for example, 50 seconds). Further, in STEPs 33 and 34, it is determined whether or not the elapsed time after starting, which is the current time measured by the first timer, is shorter than a predetermined time TM2 (in this embodiment, TM2 is, for example, 10 minutes). And when the judgment result of both STEP33 and 34 becomes affirmative, the control unit 50 has a high possibility that the dish currently performed with the cooking container W is a steamed dish, Therefore This dish is a steamed dish. Judge that there is. In addition, when the determination result of any one of STEPs 33 and 34 is negative, the control unit 50 is unlikely to be a steamed dish (in other words, a boiled dish). Therefore, it is determined that the dish is not a steamed dish.

  In addition, you may make it judge whether the cooking currently performed with the cooking container W is a steamed baked food using the other methods as seen in patent document 2, for example.

  If the determination result of both STEPs 33 and 34 is affirmative and the control unit 50 determines that the dish being cooked in the cooking container W is a steamed dish, the control unit 50 further relates to the stove burner 4x in STEP 35. It is determined whether the degree of the requirement for non-sticking represented by the set value of the non-burning prevention requirement level Kx_lb is high or low. In STEP 35, the control unit 50 determines whether the burn prevention requirement is high or not depending on whether the set value of Kx_lb is, for example, “3” or more. That is, when the set value of Kx_lb is “3” or more (when Kx_lb = 3, 4 or 5), the control unit 50 determines that the degree of demand for prevention of burning is low, and the set value is “3”. If it is smaller than "" (when Kx_lb = 1 or 2), it is determined that the degree of demand for burn prevention is high. In the present embodiment, the first determination means in the present invention is realized by the determination process of STEP 35.

  When the determination result in STEP 35 is affirmative (Kx_lb ≧ 3) and it is determined that the degree of demand for prevention of burn is low, the control unit 50 determines that the control process for preventing burn is not executed and the equilibrium temperature is determined. TH is canceled (STEP 36), and the process returns to STEP23. Note that releasing the equilibrium temperature TH in STEP 36 means that the phenomenon that the temperature of the cooking container W has reached the equilibrium temperature TH has not occurred.

  In addition, when the determination result of STEP 33 or 34 is negative and it is determined that the cooking performed in the cooking container W is not steamed cooking, or the determination result of STEP 35 is negative (Kx_lb <3), When it is determined that the degree of demand for non-burning is high, the control unit 50 executes the process of FIG. 6 including the non-burning control process while storing and holding the equilibrium temperature TH.

  In the process of FIG. 6, the control unit 50 executes the determination processes of STEPs 37 to 39. In the determination processes of STEPs 37 and 38, whether or not the cooking container W is lifted by the user from the position on the virtues 7x that is a predetermined placement position with respect to the stove burner 4x is determined based on whether the detected temperature TS of the cooking container W is the equilibrium temperature TH This is a process for making a determination based on the pattern of change over time after reaching. Further, the determination process of STEP 39 is a process for determining whether or not the non-sticking prevention request level Kx_lb set with respect to the burner 4x is high (whether the request degree is high or low).

  Here, when the cooking performed in the cooking container W is a simmered dish, in a stage where the moisture in the cooking container W has decreased (a situation where the temperature of the cooking container W rises from the equilibrium temperature), In many cases, the user temporarily lifts the cooking container W from the top of the five virtues 7x (so-called pan-up) for the purpose of moving the food in the cooking container W or the like. In such a case, while the cooking container W is being lifted, the combustion heat of the stove burner 4x acts directly on the temperature sensor 8x, and the temperature detected by the temperature sensor 8x is likely to rise rapidly. For this reason, when the above-mentioned pan cooking is performed, when the control process for non-sticking is executed in the same way as the case where the cooking container W is constantly placed on the Gotoku 7x, There is a case where the burner 4x is automatically extinguished more quickly than necessary (before burning occurs). Therefore, it may be preferable to include a condition that the pot is not raised as a necessary condition for executing the burn prevention control process.

  On the other hand, as described above, the setting value of the non-burning prevention requirement level Kx_lb set by the user is smaller, which means that the degree of the requirement for prevention of burning of the cooked food assumed by the user is higher (the allowable degree of burning is higher). Means low). And, when the degree of demand for prevention of scorching of the cooked food assumed by the user is relatively high, it is certain to prevent scorching of the cooked food even if the pot is likely to be raised. In order to improve the performance as much as possible, it is considered desirable to extinguish the stove burner 4x when the temperature of the cooking vessel W does not become so high.

  Therefore, in the present embodiment, as a necessary condition for the control unit 50 to execute the control process for preventing the burning, in addition to the first condition, the pot raising for temporarily lifting the cooking container W is not performed. Or a condition that the degree of demand for non-sticking represented by the set value of the non-burning prevention requirement level Kx_lb is high (this corresponds to the third condition in the present invention).

  In this case, in this embodiment, it is determined whether the cooking container W is temporarily lifted by the determination process of STEP37, 38 among the determination processes of STEP37-39 (whether the pan is raised). Is judged. Therefore, in this embodiment, the cooking container lifting judgment means in the present invention is realized by the processing of STEPs 37 and 38.

  In this embodiment, this determination is made as follows. That is, when the cooking container W is lifted, the temperature detected by the temperature sensor 8x rapidly increases as described above.

  Therefore, in the present embodiment, the control unit 50 determines whether or not the second post-equilibrium rising time, which is the final time measured by the second timer, is shorter than a predetermined time TM3 (in this embodiment, TM3 is 20 seconds, for example). Further, in STEPs 37 and 38, it is determined whether or not the post-equilibrium third rise time, which is the final timing time of the third timer, is shorter than a predetermined time TM4 (in this embodiment, TM4 is, for example, 25 seconds). And when the judgment result of both STEP37 and 38 becomes affirmative, the control unit 50 judges that the cooking container W is temporarily lifted (pan cooking is performed). In addition, the control unit 50 determines that the cooking container W is not lifted when the determination result of any of STEPs 37 and 38 is negative.

  In addition, you may make it judge whether the cooking container W is lifted using the same method as the pot raising judgment as seen in paragraph 0039 of patent document 2, for example.

  Further, when the control unit 50 determines that the determination results of both STEPs 37 and 38 are affirmative and the cooking container W is temporarily lifted (pan cooking is being performed), STEP 39 is further performed. The determination of whether or not the non-burning prevention request level represented by the set value of the non-burning prevention request level Kx_lb related to the stove burner 4x is made is made. In this STEP 39, the control unit 50 determines the level of the degree of request for prevention of burning depending on whether or not the set value of Kx_lb is “2” or more, for example. That is, when the set value of Kx_lb is “2” or more (when Kx_lb ≠ 1), the control unit 50 determines that the degree of request for prevention of burning is low, and the set value is smaller than “2”. In this case (when Kx_lb = 1), it is determined that the degree of demand for prevention of burning is high. In the present embodiment, the second determination means in the present invention is realized by the determination processing in STEP39.

  Then, if the determination result in STEP 39 is affirmative (Kx_lb ≧ 2) and it is determined that the degree of demand for non-sticking is low, the control unit 50 determines that the non-sticking prevention control process is not executed and the temperature sensor 8x It is determined whether or not the detected temperature TS by the temperature rises to a temperature higher than a temperature that is higher than the equilibrium temperature TH by a second predetermined temperature (100 ° C. in the present embodiment) (STEP 40). The second predetermined temperature is a temperature that is predetermined at a temperature higher than the first predetermined temperature (50 ° C., 40 ° C., or 30 ° C. in the present embodiment) in the first condition.

  In this case, if the determination result in STEP 40 is negative, the process of the control unit 50 enters a standby state. And when the judgment result of STEP40 becomes affirmative, the control unit 30 performs the fire extinguishing process of the stove burner 4x (STEP41). In this fire extinguishing process, the solenoid valve 34x is closed. Thereby, supply of the fuel gas to the stove burner 4x is interrupted, and the stove burner 4x is extinguished.

  Accordingly, it is determined that the cooking container W is being lifted (the pan is being raised) by the determination process of STEPs 37 and 38, and is represented by the set value of the non-burning prevention request level Kx_lb by the determination process of STEP39. The condition that it is determined that the required degree of non-burning prevention is determined is satisfied, and the detected temperature TS by the temperature sensor 8x rises to a temperature higher than the equilibrium temperature TH by a second predetermined temperature (100 ° C.). When the condition is satisfied, the combustion operation of the stove burner 4x is stopped. In the present embodiment, the processing of STEP 40 that is executed when the determination result of STEP 40 is affirmative corresponds to the cooking container lifting support control processing according to the present invention.

  Supplementally, in STEP 39, it is determined whether the degree of the requirement for non-sticking is low or high depending on whether or not the setting value of the non-sticking requirement level Kx_lb is “2” or more. In the same manner as in (Ref.), It may be determined whether the required degree of non-sticking is low or high depending on whether or not the set value of Kx_lb is “3” or more. As described above, the setting values of Kx_lb for distinguishing the degree of the degree of demand for prevention of burn in the determination processes of STEP 35 and 39 do not need to be different from each other, and may be the same value.

  On the other hand, if the determination result in STEP 37 or 38 is negative and it is determined that the cooking container W is not lifted, or the determination result in STEP 39 is negative (Kx_lb = 1), the degree of demand for prevention of burning When it is determined that the value is high, the control unit 50 executes the burn prevention control process from STEP42.

  In the burn prevention control process, the control unit 50 monitors whether or not the first condition is satisfied using a first predetermined time determined according to the burn prevention request level Kx_lb.

  More specifically, the control unit 50 determines whether or not the setting value of the non-burning prevention request level Kx_lb for the stove burner 4x is “5” (STEP 42). When Kx_lb = 5, the control unit 50 sets the second predetermined temperature to 50 ° C., which is a temperature corresponding to Kx_lb = 5, and the detected temperature TS is a second value higher than the equilibrium temperature TH. It is monitored whether or not the temperature has risen by a predetermined temperature (50 ° C.) (STEP 43).

  If Kx_lb ≠ 5 in STEP 42, the control unit 50 determines whether or not the setting value of the non-burning prevention request level Kx_lb is “4” (STEP 44). When Kx_lb = 4, the control unit 50 sets the second predetermined temperature to 40 ° C., which is a temperature corresponding to Kx_lb = 4, and the detected temperature TS is a second value higher than the equilibrium temperature TH. It is monitored whether or not the temperature has risen by a predetermined temperature (40 ° C.) (STEP 45).

  Further, when Kx_lb ≠ 4 in STEP 44 (when Kx_lb = 1, 2 or 3), the control unit 50 sets the second predetermined temperature to 30 ° C. which is a temperature corresponding to the case where Kx_lb ≦ 3. Then, it is monitored whether or not the detected temperature TS has risen to a temperature that is higher than the equilibrium temperature TH by a second predetermined temperature (30 ° C.) (STEP 46).

  Then, when the detected temperature TS rises and the determination result of STEP 43, 45, or 46 becomes affirmative, the control unit 50 performs the processing of STEP 41, that is, the control of the stove burner 4x in order to prevent the cooked food from burning. Perform fire fighting.

  As described above, in the non-burning control process realized by the processes of STEP 42 to 46 and STEP 41, the first predetermined temperature in the first condition is variably determined according to the set value of the non-burning prevention request level Kx_lb. The For this reason, when the detected temperature TS of the cooking container W rises to a temperature suitable for the degree of demand for prevention of burning, which is assumed by the user, the stove burner 4x can be extinguished. Eventually, it is possible to prevent a situation in which the burner 4x is automatically extinguished when the cooked food of the simmered dish becomes excessive for the user or the burnt is too little. Can do.

  In the present embodiment, as a necessary condition for executing the control process for preventing the burning, in addition to the first condition, it is determined that the cooking performed in the cooking container W is not a steamed dish, or preventing the burning. A condition that the request level Kx_lm is smaller than “3” (the degree of request for non-burning is relatively high) is included. For this reason, not only when the dish actually performed in the cooking container W is not a steamed dish, but also when it is determined that the dish is a steamed dish, As in the case where the dish is a boiled dish, the non-burning control process can be executed. Therefore, not only when the actual boiled food is correctly judged, but also when the food is actually boiled food but it is misjudged as steamed food, The operation of the stove burner 4x can be performed so as to prevent scorching.

  Further, in the present embodiment, as a necessary condition for executing the non-burning control process, in addition to the first condition, after the temperature of the cooking container W reaches the equilibrium temperature TH, the cooking container W is temporarily stored. It is determined that the raising (pan raising) is not performed, or the condition that the non-burning prevention request level Kx_lm is smaller than “2” (the degree of non-burning prevention is relatively high) is also included. For this reason, after the temperature of the cooking container W reaches the equilibrium temperature TH, the cooking container W is burnt even if the cooking container W is constantly placed on the virtues 7x or when the pan is raised. When the prevention degree is high, the burn prevention control process can be executed. Therefore, the operation of the stove burner 4x can be performed so as to satisfy the user's request to prevent the food from being burned as much as possible.

  In the above-described embodiment, as a necessary condition for executing the burn prevention control process, in addition to the first condition, it is determined that the cooking performed in the cooking container W is not steamed cooking, or After the condition that the set value of the non-burning requirement level Kx_lm is smaller than “3” (the degree of requirement for non-burning is relatively high) and the temperature of the cooking vessel W reaches the equilibrium temperature TH, the cooking vessel W temporarily It is judged that the basic lifting (panning) has not been performed, or two conditions are included: the requirement level for preventing non-stick Kx_lm is smaller than “2” (the degree of requirement for non-sticking is relatively high) However, both of these conditions or one of the conditions may be excluded.

  In the present embodiment, when the set value of the non-burning prevention request level Kx_lm is “3” or less, the first predetermined temperature in the first condition is set to the same value (30 ° C.), but the set value of Kx_lm Even when “3” is equal to or lower than “3”, the first predetermined temperature may be decreased as the set value of Kx_lm is smaller (the higher the degree of demand for non-sticking).

  In this embodiment, the value of the non-burning prevention request level Kx_lm decreases as the degree of non-burning prevention required increases. However, the value of the non-burning prevention request level Kx_lm increases as the non-burning prevention request level increases. You may do it. Furthermore, the value of the non-burning prevention request level Kx_lm does not necessarily have to be a numerical value. For example, the degree of the non-burning prevention request may be expressed by a code such as an alphabet.

  Further, in the present embodiment, in the burn prevention control process, when the detected temperature TS of the cooking vessel W rises to a temperature higher than the equilibrium temperature TH by a first predetermined temperature or more, the conburner 4 is extinguished (combustion operation). However, by controlling the flow rate adjusting valve 35, the amount of heat generated by the burner 4 (thermal power) is reduced (for example, the flow rate so that the thermal power of the burner 4 becomes a predetermined minimum thermal power). The control valve 35 may be controlled).

  Moreover, in this embodiment, although the gas stove provided with the several stove burner was taken as an example and demonstrated as a heating cooker, the gas stove provided with the single stove burner, the electric heater, and the IH heater were provided as a heating source. Of course, the present invention can also be applied to a cooking device.
