Description

  The present invention includes a heating unit that heats an object to be heated placed on a placement unit provided in a grill cabinet, a position where the ambient temperature rises after the heating unit starts heating, and the heating unit Temperature detection means for measuring the ambient temperature at a position where the temperature rise state differs according to the difference in heat capacity of the object to be heated, and based on detection information of the temperature detection means, heating by the heating means is started and a set time has elapsed After the measurement starts from the measurement start time until the measurement end time, the amount of temperature rise is calculated, and heating is started based on the amount of temperature rise before heating for cooking the object to be heated. The present invention relates to a grill device configured to include control means for obtaining cooking heating time until completion.

  Conventionally, as the above grill apparatus, a grill apparatus that includes a gas combustion type upper burner and a lower burner as heating means and places an object to be heated on a grill net as a placing portion and heats it. In the application, a temperature sensor for detecting an atmospheric temperature is provided in the exhaust passage for exhausting the exhaust from the grill to the outside as the temperature detecting means, and an object to be heated is placed in the grill The temperature increase amount during the elapsed time for measurement after starting heating in the state is obtained, and an arithmetic expression indicating the relationship between the temperature increase amount set in advance based on experimental data or the like and the heating time is used. In some cases, an appropriate heating time corresponding to an object to be heated is obtained (for example, see Patent Document 1).

JP 2005-102846 A

  The above conventional configuration utilizes the fact that when the heat capacity of the object to be heated changes, the temperature increase amount changes accordingly, and the heat capacity of the object to be heated using the temperature increase amount detected by the temperature detecting means. The cooking heating time for performing appropriate cooking is determined in accordance with the above. That is, in the grill device, if the heat capacity of the object to be heated is small, the amount of heat consumed for cooking the object to be heated out of the amount of heat output from the heating means is small, and the ambient temperature detected by the temperature detecting means However, if the heat capacity of the object to be heated is large, the amount of heat consumed for cooking the object to be heated is large if the heat capacity of the object to be heated is large. Since the ambient temperature detected by the detecting means slows down and the temperature rise is small, it is suitable for the heat capacity of the object to be heated by measuring the temperature rise using such points. The heating time for cooking is obtained.

  By the way, in the above-mentioned conventional configuration, a good result can be obtained when the exhaust resistance when the cooking exhaust in the grill device is discharged to the outside is not so large. However, the above-described conventional configuration is applied to the grill device having a large exhaust resistance. When the heat capacity of the object to be heated increases, the cooking heating time may not be set as an appropriate time according to the amount of the object to be heated, and cooking cannot be performed satisfactorily. There was a disadvantage.

  That is, in the grill device, fish or the like is often heated as a cooked product, but the oil generated from such cooked product may ignite and a flame may be generated in the grill cabinet. Therefore, for example, a porous flame extinguishing member is provided in order to prevent a flame generated in the grill cabinet from overflowing outward from the exhaust outlet in an exhaust passage for exhausting cooking exhaust generated by heating cooking to the outside. May be installed. When the above-described conventional configuration is applied to a grill apparatus having such a flame extinguishing member provided in the exhaust passage, when the heat capacity of the object to be heated is large, the heating time set according to the amount of temperature rise is long. Insufficient heating sometimes prevented sufficient heating.

  Therefore, as a result of examination by the applicant of the present invention using a grill device including a gas combustion type upper burner and a lower burner as heating means, the exhaust resistance is large as in the configuration provided with the above-described flame extinguishing member. In such a case, when the heat capacity of the object to be heated is small, the temperature increase tends to decrease as the heat capacity increases, but when the heat capacity of the object to be heated is large, the heat capacity of the object to be heated is small. The larger the temperature rises, the larger the temperature rise.

  This is considered to be caused by the following. In the grill device having a large exhaust resistance, in addition to reducing the intake of combustion air due to the draft action of exhaust gas in the exhaust passage, in addition, when the heat capacity of the object to be heated is large, for example, on the grill net as the mounting portion described above In the case where the objects to be heated are arranged without gaps, the amount of combustion air for the upper burner flowing upward through the grille is reduced by the draft action of the exhaust gas due to the combustion of the lower burner, and the temperature due to the exhaust gas of the upper burner As the heat capacity of the object to be heated increases, the exhaust gas from the lower burner increases the proportion of the lower burner where the cooked food is juxtaposed without any gap to the exhaust part. This is because the tendency of the temperature to rise increases with the increase in the heat capacity of the object to be heated.

  As described above, in the predicted range of the heat capacity of the object to be heated, a range in which the temperature increase amount decreases as the heat capacity of the object to be heated increases, and a range in which the temperature increase amount increases as the heat capacity of the object to be heated increases. Since the heat capacity of the object to be heated cannot be properly estimated only from the measurement result of the temperature increase amount, the cooking heating time cannot be obtained as an appropriate one corresponding to the heat capacity of the object to be heated. .

  Therefore, the present invention has been made paying attention to this point, and the purpose thereof is cooking corresponding to the heat capacity of the object to be heated even when the exhaust resistance when discharging the cooking exhaust to the outside is large. It is in the point which provides the grill device which can obtain | require the heating time appropriately.

A grill device according to the present invention includes a heating unit that heats an object to be heated placed on a placement unit provided in a grill cabinet,
A temperature detecting means for measuring the ambient temperature at a position where the ambient temperature rises after the heating means starts heating and a temperature rise state is different according to the difference in the heat capacity of the object to be heated; and
Based on the detection information of the temperature detection means, the amount of temperature rise during the elapsed time for measurement from the measurement start time to the measurement end time after the set time elapses after starting heating by the heating means is obtained. And a control means for obtaining a heating time for cooking from the start of heating based on the amount of temperature rise to the end of heating for cooking the object to be heated,
The first characteristic configuration is that a pair of temperature detection units as the temperature detection means includes
In the small heat capacity range in which the heat capacity is small in the predicted heat capacity variation range of the object to be heated, the rate of change of the temperature increase with respect to the change in the heat capacity of the object to be heated is the same or substantially the same. The larger the heat capacity of the object to be heated, the smaller the temperature increase amount. In the large heat capacity range where the heat capacity is large, the temperature increase amount with respect to the change in the heat capacity of the object to be heated is different from each other. Dispersed and deployed in such a position that the amount of temperature rise increases as the heat capacity of the object increases,
The control means is configured to determine the temperature increase amount based on detection information of each of the pair of temperature detection units, and to determine the cooking heating time based on the pair of temperature increase amounts. There is in point.

  According to the first characteristic configuration, when cooking heating by the heating unit is started in a state where the object to be heated is placed on the placement unit, the temperature in the grill box increases due to the heating of the heating unit. The control means, based on the detection information of each of the pair of temperature detection units, while the measurement elapsed time from the measurement start time to the measurement end time after the set time elapses after starting heating by the heating means. The amount of temperature rise in each is obtained, and the heating time for cooking from the start of heating based on the pair of temperature rise amounts to the end of heating for cooking the object to be heated is obtained.

  At this time, if the exhaust resistance of the grill device is large, the respective temperature increase amounts detected by the pair of temperature detection units are small in the predicted heat capacity variation range of the object to be heated. In the small heat capacity range, the rate of change in the temperature rise with respect to the change in the heat capacity of the heated object is the same or substantially the same, and the larger the heat capacity of the heated object, the smaller the temperature rise, and the large heat capacity range where the heat capacity is large. In this case, the rate of change in temperature rise with respect to the change in the heat capacity of the object to be heated is different, and the amount of increase in temperature increases as the heat capacity of the object to be heated increases.

  And a control means calculates | requires the said temperature rise amount separately based on the detection information of each of a pair of temperature detection part, and calculates | requires the said cooking heating time based on the said pair of said temperature rise amount. For example, it is determined whether the heat capacity of the object to be heated at this time is in a large range or a small range by comparing the respective temperature rise amounts detected by the pair of temperature detection units. It is possible to obtain an appropriate cooking heating time corresponding to the heat capacity by various calculation methods such as obtaining the cooking heating time from one of the temperature rises.

  Therefore, according to the 1st characteristic composition, even if it is a case where exhaust resistance at the time of discharging cooking exhaust outside is large, it becomes possible to ask for cooking heating time corresponding to the heat capacity of a thing to be heated appropriately. A grill device can be provided.

In the second feature configuration of the present invention, in addition to the first feature configuration, the pair of temperature detection units includes:
Even if the heat capacity of the object to be heated is the same, the amount of temperature rise during the elapsed time for measurement from the measurement start time to the measurement end time after the set time elapses after the heating by the heating means is started. Deployed in different positions,
The control means is
A correction temperature increase amount obtained by multiplying the other temperature increase amount by a preset coefficient is subtracted from one of the temperature increase amounts measured by each of the pair of temperature detection units. Thus, in both the small heat capacity range and the large heat capacity range, a corrected temperature increase amount that decreases the temperature increase amount as the heat capacity increases is obtained, and the cooking heating time is determined based on the corrected temperature increase amount. It is in the point where it is constituted to ask.

  According to the second characteristic configuration, even if the heat capacity of the object to be heated is the same, the temperature increase amounts detected by the pair of temperature detection units are detected as different values. Then, the control means first sets one of the temperature rise amounts measured by each of the pair of temperature detection units as a reference, and is preset to the other temperature rise amount. A corrected temperature increase amount obtained by multiplying the coefficient is obtained, and the corrected temperature increase amount is obtained by subtracting the corrected temperature increase amount from one of the reference temperature increase amounts. At this time, the corrected temperature increase amount is obtained as a value in which the temperature increase amount decreases as the heat capacity increases in both the small heat capacity range and the large heat capacity range. In short, from the respective temperature rises detected by the pair of temperature detectors, one temperature rise is used to cover the other temperature rise over the entire range of the expected heat capacity fluctuation range of the object to be heated. Correction is performed in such a state that the amount of temperature increase is smaller as the heat capacity of the heated object is larger.

  Referring to FIG. 18 showing the applicant's experimental data, the corrected temperature increase amount (A) is obtained by multiplying the temperature increase amount (ΔUt) detected by one of the temperature detectors by a preset coefficient (A). X ΔUt). Then, the corrected temperature rise amount (Δt) is obtained by subtracting the corrected temperature rise amount (A × ΔUt) from the temperature rise amount (ΔDt) detected by the other temperature detection unit. FIG. 18 shows changes in measured values when the heat capacity of the object to be heated is variously changed. In an actual apparatus, when the heat capacity of the object to be heated is determined, for example, on each line in FIG. It is obtained as a fixed value determined at one point. As can be seen from the figure, the corrected temperature rise amount (Δt) is obtained as a value that decreases as the heat capacity increases in both the small heat capacity range and the large heat capacity range.

  As described above, the correction temperature increase amount is obtained as a value that decreases the temperature increase amount as the heat capacity increases in both the small heat capacity range and the large heat capacity range. From this corrected temperature increase amount, it becomes possible to obtain the heat capacity of the object to be heated corresponding to the corrected temperature increase amount, and an appropriate cooking heating time corresponding to the heat capacity of the object to be heated.

  Therefore, according to the second feature configuration, by a simple calculation process of multiplying one of the temperature increase amounts measured by each of the pair of temperature detection units by a coefficient and subtracting from the other temperature increase amount. Thus, it has become possible to provide a grill apparatus that can appropriately determine the heating time for cooking corresponding to the heat capacity of the object to be heated.

  According to a third characteristic configuration of the present invention, in addition to the first characteristic configuration or the second characteristic configuration, the heating unit is configured to be able to change and adjust a heating amount, and when the control unit starts heating, the heating is set. The heating means is controlled in such a manner that when the heating amount switching time set according to the cooking heating time elapses after the heating is started, the heating amount is changed to a lower heating amount lower than the set heating amount. The point is that it is configured to do.

  According to the third characteristic configuration, the control means adjusts the heating amount of the heating means to the set heating amount when starting the cooking of the article to be heated, and starts the heating and then responds to the cooking heating time. When the set heating amount switching time elapses, the heating amount of the heating means is changed to a low heating amount lower than the set heating amount. That is, from the start of heating until the heating amount switching time elapses, the cooking is performed at a set heating amount that is set as an appropriate value for efficiently cooking the object to be heated. When the amount switching time has elapsed and the cooking heating of the object to be heated has progressed to some extent, the amount of heating is changed to a low heating amount, so that it is easy to avoid the disadvantage that the object to be heated burns. In addition, since the heating by the heating means continues until the cooking heating time elapses, there is little possibility that the heating is insufficient and the cooking with respect to the object to be heated is incomplete, and proper cooking can be performed. Become.

  Therefore, according to the 3rd characteristic structure, it came to be able to provide the grill device which can perform an appropriate heat cooking, avoiding the disadvantage that a to-be-heated object will burn.

The control means is based on the detection information of the temperature detection means and the calculation condition selected according to the cooking menu commanded by the cooking menu command means from among a plurality of calculation conditions. It is in the point comprised so that a heating time may be calculated | required.

  According to the fourth feature configuration, when the cooking menu according to the object to be heated is instructed by the cooking menu instruction means, the control means is the cooking menu instructed by the cooking menu instruction means among the plurality of calculation conditions. The cooking heating time is obtained based on the calculation condition selected according to the temperature and the detection information of the temperature detection means. That is, a plurality of calculation conditions for calculating the cooking heating time are prepared for each of the plurality of cooking menus, and the calculation conditions are selected according to the commanded cooking menu among the plurality of calculation conditions, Since the cooking heating time is obtained based on the selected calculation condition, the cooking heating time is set as an appropriate time corresponding to the cooking method at that time.

  Therefore, according to the fourth feature configuration, when the user commands a desired cooking menu using the cooking menu command means, the cooking heating time is set as an appropriate time corresponding to the cooking method at that time. As a result, an easy-to-use grill device can be provided.

  In addition to any of the first to fourth feature configurations, the fifth feature configuration of the present invention is such that the exhaust path connected to the grill box and guiding the cooked exhaust to the upper exhaust outlet is closer to the upper side. A foreign object that is formed in an inclined posture away from the grill cabinet and that has fallen and entered through the exhaust outlet to the bottom side of the exhaust passage at a location that is offset toward the grill cabinet side from the upper end side portion in the exhaust passage to the grill cabinet side. A porous flame extinguishing member is provided in a form that forms an opening for constituting a foreign substance passage to be passed and crosses the exhaust passage, and an exhaust guide member that guides cooking exhaust from the grill box to the flame extinguishing member.

There is a point.

  According to the fifth characteristic configuration, the flame extinguishing member is provided at a location that is offset toward the grill box side from the upper end side part in the exhaust path, so that the flame generated in the grill box reaches the upper end side part in the exhaust path. In the state that is still a small flame before becoming such a large flame, the flame extinguishing member can exert a flame extinguishing action, so that a large flame that reaches the upper end side portion in the exhaust passage is located on the upper end side portion. Compared to the case where the flame is extinguished by the flame extinguishing member, there is less possibility that the flame overflows outward from the exhaust outlet, and safety in use can be improved.

  Further, the flame extinguishing member forms an opening on the bottom side of the exhaust passage to form a foreign matter passage that allows foreign matter that has fallen and entered through the exhaust outlet to pass through the grill cabinet, and crosses the exhaust passage. The foreign matter dropped and intruded through the exhaust outlet is received by the upper part of the flame extinguishing member and passes through the foreign material passage to the grill box side without accumulating. In this way, the foreign matter that has passed through the foreign matter passage to the side of the grill can be removed through an opening or the like provided for taking in and out the object to be heated in the grill.

  In addition, in this type of grill device, foreign substances such as pieces of food to be cooked may fall into the exhaust passage through the exhaust outlet as it is used. The foreign material that has fallen and entered is received by the upper part of the flame extinguishing member, and does not accumulate, so that the flame extinguishing member can be prevented from being clogged, and the desired extinguishing action can be maintained. It is provided at a location that is closer to the grill cabinet side than the upper end side portion in the road, so that the flame extinguishing member can exert a flame extinguishing action when the flame generated in the grill cabinet is still small.

  In addition, the cooking exhaust from the grille is guided to the flame extinguishing member by the exhaust guide member, and the exhaust guide member guides the cooking exhaust so that the cooking exhaust flows through the foreign substance passage. In addition, since the foreign matter that has fallen and entered through the exhaust outlet is provided so as not to be retained, the foreign matter that has fallen and entered through the exhaust outlet is received by the exhaust guide member and does not accumulate and passes through the foreign matter passage. In addition, since the cooking exhaust is prevented from flowing through the foreign substance passage, even if a flame is generated in the grill, the flame is exhausted together with the cooking exhaust. It will be guided to the extinguishing member by the member, and it will prevent overflowing from the exhaust outlet through the foreign substance passage, and the desired extinguishing action by the extinguishing member It can be exhibited.

  Therefore, according to the fifth feature configuration, the flame extinguishing member exerts a desired flame extinguishing action when the flame generated in the grill is still small, and prevents the flame from overflowing from the exhaust outlet through the foreign substance passage. However, it has been possible to provide a grill device that can exert a desired flame-extinguishing action by the flame-extinguishing member and can enhance safety in use.

It is provided in a state in which the foreign matter that has fallen and entered through is not received and retained.
That is, a plate-shaped exhaust guide member 43 that is wide in the lateral direction is provided in a state that extends from the lower end portion of the flame extinguishing member 40 to the front side, that is, the grill store 32 side, and obliquely downward, and the grill store of the exhaust guide member 43 The end portion on the 32 side is configured to be located near the back side end portion of the grill 33 and slightly below the grill 33. The exhaust guide member 43 is provided so as to be shifted in the horizontal direction so as not to overlap the exhaust outlet 35 in plan view, and is provided in a state in which foreign matter that has fallen and entered through the exhaust outlet 35 is not received and retained. .

  The lower side surface 34a of the exhaust pipe 34 constituting the bottom of the exhaust path R extends over the entire area from the position where the foreign matter falling from the exhaust outlet 35 is received until it is connected to the grill warehouse 32. It is comprised so that it may become the inclination attitude | position which is located below, so that the warehouse 32 is approached. That is, the lower side surface 34a of the exhaust pipe 34 is formed as an inclined guide surface that guides the foreign matter falling and entering through the exhaust outlet 35 into the grill warehouse 32, and the lower side surface 34a of the exhaust path R and the exhaust guide. The member 43 forms a foreign matter passage 41 through which foreign matter that has fallen and entered through the exhaust outlet 35 passes to the grill cabinet 32 side.

  A porous dustproof member 44 having a large number of ventilation holes smaller than the narrowest portion of the foreign substance passage 41 and larger than the ventilation holes 40a of the flame extinguishing member 40 is provided at the exhaust outlet 35 in the exhaust passage R. Is provided. When the description is added, the dust-proof member 44 is configured by a lath net, which is a wire net having a large number of ventilation holes 44a, like the flame-extinguishing member 40, and an opening of the exhaust outlet 35 in the exhaust path R. It is provided so as to cover the entire area. In this lath net, the size of each vent hole 44a (mesh size) is set to 12 mm × 6 mm, and the vertical width (about 20 mm), which is the width of the narrowest part of the foreign substance passage 41, is set. The vent hole 40a is smaller and larger than the vent hole 40a of the flame extinguishing member 40, and the exhaust resistance is not increased and the cooked exhaust is exhausted to the outside.

  When the heated object N such as fish placed on the grill 33 is heated, a flame is generated by igniting oil generated from the heated object N, and the flame is exhausted along with the cooking exhaust. Even if it is guided and extended toward the exhaust outlet 35, the cooking exhaust is guided toward the flame extinguishing member 40 by the exhaust guide member 43 at that time. The flame is extinguished by the extinguishing action.

  Even if a foreign object such as a broken piece of food such as vegetable chips passes through the dust-proof member 44 and falls into the exhaust path R from the exhaust outlet 35, the foreign object is formed on the inclined guide surface. The exhaust pipe 34 is guided to flow down into the grill 32 by passing through the foreign substance passage 41 by the lower side surface 34a of the exhaust pipe 34. The foreign matter collected in the grill box 32 can be removed through an opening for taking in and out the object to be heated formed on the front side of the grill box 32.

  The grill is provided with temperature detection means K for measuring the ambient temperature at a location where the amount of temperature rise changes according to the difference in the heat capacity of the object to be heated, and the control unit H detects the temperature detection means K. Based on the information, the amount of temperature rise during the elapsed time for measurement from the measurement start time to the measurement end time after starting heating by the grill burner 2 is obtained, and heating is started based on the temperature rise amount. The heating time for cooking until the heating for cooking with respect to the to-be-heated material N is complete | finished is comprised.

  In this grill, the temperature sensors 45 and 46 which are a pair of temperature detection units as the temperature detection means K have a small heat capacity range in which the heat capacity is small in the predicted heat capacity fluctuation range of the object N to be heated. In the above, the rate of change in the temperature increase with respect to the change in the heat capacity of the object to be heated N is the same or substantially the same, and as the heat capacity of the object to be heated N increases, the amount of temperature increase decreases and the heat capacity increases. In the range, in a state where the rate of change in the temperature increase with respect to the change in the heat capacity of the object to be heated N is different from each other, the temperature increase amount increases as the heat capacity of the object to be heated N increases. Is provided.

  More specifically, as shown in FIG. 4 and FIG. 5, it is a position slightly higher than the height of the grill 33 in the grill warehouse 32, and is the central position in the lateral direction on the upper side of the exhaust guide member 43. Further, an upper side temperature sensor 45 as one temperature detection unit made of a thermistor is provided. The upper side temperature sensor 45 is provided at a position where the combustion exhaust gas of the upper surface burner 2a flows and the combustion exhaust gas flowing upward through the grill 33 among the combustion exhaust gases of the pair of left and right lower surface burners 2b and 2c. A position where the temperature rises while the elapsed time for measurement from the measurement start time to the measurement end time elapses after heating by the grill burner 2 varies depending on the heat capacity of the object N to be heated. It is.

  In addition to the upper side temperature sensor 45, a position that is slightly lower than the grill 33 in the grill 32 and is located in the foreign matter passage 41 and mainly where the combustion exhaust gas from the lower burners 2b and 2c flows. Is provided with a lower temperature sensor 46 as the other temperature detector. The position where the lower temperature sensor 46 is provided is such that the amount of temperature rise during the elapsed time for measurement from the measurement start time to the measurement end time after heating by the grill burner 2 is large in the heat capacity of the object N to be heated. It is a different position depending on the height.

  The positions where the upper temperature sensor 45 and the lower temperature sensor 46 are installed are measured after the set time has elapsed since the heating by the grill burner 2 was started even if the heat capacity of the object to be heated N was the same. The amount of temperature increase during the elapsed time for measurement from the start point to the end point of measurement is different from each other, and furthermore, a small heat capacity with a small heat capacity within the predicted range of heat capacity of the object to be heated N In the range, the rate of change in the temperature increase with respect to the change in the heat capacity of the object to be heated N is the same or substantially the same, and the heat capacity of the object to be heated N increases as the heat capacity of the object to be heated increases and the heat capacity increases. In the range, the temperature increase amount increases as the heat capacity of the object to be heated N increases while the rate of change of the temperature increase with respect to the change in the heat capacity of the object to be heated N is different from each other. Is a position.

  And after the said control part H started the heating by the grill burner 2 separately based on the detection information of each of a pair of temperature detection part, ie, the upper side temperature sensor 45, and the lower side temperature sensor 46, after setting time passed The temperature rise amounts ΔUt and ΔDt during the elapsed time for measurement from the measurement start time to the measurement end time are obtained, and the cooking heating time is obtained based on the pair of the temperature rise amounts ΔUt and ΔDt. It is configured. Specifically, the control unit H obtains a corrected temperature increase amount obtained by multiplying one of the pair of temperature increase amounts ΔUt and ΔDt by a preset coefficient to the other temperature increase amount. Is subtracted from the small heat capacity range and the large heat capacity range to obtain a corrected temperature increase amount that decreases the temperature increase amount as the heat capacity increases, and the cooking heating is based on the corrected temperature increase amount. It is configured to ask for time.

  In FIG. 18, using the upper side temperature sensor 45 and the lower side temperature sensor 46, the heating by the grill burner 2 with respect to the change in the heat capacity of the object to be heated N is started, and the measurement ends from the measurement start time when the set time has elapsed. The measurement result which measured the change of the temperature rise amount during the elapsed time for measurement until a time point is shown. That is, the temperature rise amount ΔUt measured by the upper side temperature sensor 45 and the temperature rise amount ΔDt measured by the lower side temperature sensor 46 change with respect to changes in the heat capacity of the object N to be heated. The graph is shown. Incidentally, the heat capacity of the object N to be heated varies depending on whether it is a raw fish or a dried fish, and also varies depending on the size of the fish and the number of fish.

  As can be seen from FIG. 18, the temperature increase ΔUt measured by the upper temperature sensor 45 and the temperature increase ΔDt measured by the lower temperature sensor 46 are the heat capacity of the object N to be heated. The temperature rise amounts are different from each other even if the temperature is the same, and in the small heat capacity range P1, the rate of change in the temperature rise amount with respect to the change in the heat capacity of the object to be heated N is the same or substantially the same. The larger the heat capacity of the object, the smaller the temperature increase amount. That is, the temperature increase amount ΔUt and the temperature increase amount ΔDt are in a right-down state in parallel. In the large heat capacity range P2 where the heat capacity is large, the temperature increase amount increases as the heat capacity of the object to be heated N increases in a state where the rate of change in the temperature increase with respect to the change in the heat capacity of the object to be heated N is different from each other. Yes. That is, both the temperature rise amount ΔUt and the temperature rise amount ΔDt are in the right-up state but have different rates of change (how to bend).

  In addition, the control unit H uses the detection information of each of the upper side temperature sensor 45 and the lower side temperature sensor 46 and the calculation selected according to the cooking menu commanded by the menu changeover switch 29 among the plurality of calculation conditions. The cooking heating time is determined based on the conditions. Furthermore, the control unit H adjusts the set heating amount when starting the heating, and when the heating amount switching time Ty set according to the cooking heating time Tx elapses after starting the heating, the set heating amount. It is comprised so that the grill burner 2 may be controlled by the form which changes to the lower low heating amount.

Hereinafter, a specific control operation of the control unit H for the grill burner 2 will be described based on the control flowcharts shown in FIGS.
As shown in FIG. 7, the controller H performs a manual cooking operation when the fire extinguishing switch 23 is turned on after the power switch 9 is turned on (steps 1 and 2). As shown in FIG. 8, in this manual cooking operation, first, ignition processing for the grill burner 2 is executed (step 3). Specifically, after ignition by the igniter 7 is started, the original solenoid valve 12 and the flow rate control valve 18 are opened to ignite the grill burner 2, and when the ignition state is detected by the thermocouple 8, the igniter 7 is stopped and the combustion lamp 24 is turned on. If ignition is not confirmed by the thermocouple 8 within the set time, a non-ignition error is detected and the original solenoid valve 12 and the flow rate control valve 18 are closed to perform notification processing.

  When the grill burner 2 is ignited and the operation of the grill unit 3 is started, the heating power of the grill burner 2 is initially set so that the heating amounts of the upper surface burner 2a and the lower surface burners 2b and 2c are both strong. This initial setting state corresponds to the set heating amount.

  After the ignition of the grill burner 2 is detected, it is determined whether or not the temperature in the grill 32 is abnormal based on the detection information of the upper side temperature sensor 45 and the lower side temperature sensor 46 (step 4). ). Specifically, the detected value of the upper side temperature sensor 45 is 120 ° C. or higher and the temperature rise gradient is steep, the detected value of the upper side temperature sensor 45 is 255 ° C. or higher, the lower side temperature If any of the detected values of the sensor 46 is 180 ° C. or higher, it is determined that the temperature is abnormally high. Next, cooking time (for example, 9 minutes) initially set as a standard cooking time in the timer display unit 26 and a standard heating power, that is, the upper surface burner 2a and the pair of left and right lower surface burners 2b and 2c are both ignited. The state set to force is displayed (step 5). If there is a thermal power switching command, the thermal power is switched according to the commanded content, and the display state on the thermal power display unit 28 is switched (steps 6, 7, 8). If there is a timer time change command, the timer time is changed according to the commanded content, and the display state is changed (steps 9, 10, and 11).

  When the set timer time elapses and the timer counts up, the fire extinguishing process of the grill burner 2 is executed (steps 12 and 13). That is, the original solenoid valve 12 and the flow rate control valve 18 are closed, and the thermal power display unit 28 and the combustion lamp 24 are turned off. Further, after sounding the buzzer BZ for sound notification connected to the control unit H to make a notification and flashing the display of “00” displayed on the timer display unit 26 ten times, the process returns to Step 2 (Step S2). 14, 15). If the fire extinguishing switch 23 is turned on and fire extinguishing is instructed before the timer counts up, the fire extinguishing process as described above is executed and the process returns to step 2 (steps 16 and 17). If a temperature abnormality has occurred in the temperature abnormality determination process, after performing the fire extinguishing process, the buzzer BZ is sounded and notified, and the combustion lamp 24 flashes 10 times (steps 18 to 21). ). Since this is an abnormal state at this time, the interlock state is entered and subsequent processing is not accepted. In this case, maintenance work by a service person or the like is required.

  Then, as shown in FIG. 7, after the power switch 9 is turned on, an ignition command is not issued and at least one of the menu changeover switch 29 or the baking adjustment switch 30 is operated, and the upper temperature sensor 45 If the detected value TH1 is within a controllable range (in the range of −5 ° C. to 100 ° C.), the detected value TH2 of the lower temperature sensor 46 at that time is detected and stored as the ignition initial temperature THBO ( Steps 22, 23, 24) When the ignition is commanded, the automatic cooking operation is executed (step 25). Incidentally, even if 3 minutes have passed since the power switch 9 is turned on, if no switch is operated and there is no input operation, the power is automatically turned off and the control is terminated (steps 27, 28, 29). If the detected temperature is not within the controllable range, the buzzer BZ is sounded to generate a warning sound and the process returns to step 2 (step 26).

Next, the automatic cooking operation will be described based on the flowchart of FIG.
In this automatic cooking operation, first, ignition processing for the grill burner 2 is executed in the same manner as in the manual cooking operation (step 30), and "AU" indicating that the automatic cooking operation state is displayed on the timer display unit 26. (See FIG. 11 (a)) (step 31). And it switches to the input suppression state which suppresses reception of the input for switching operation by the menu switch 29, the heating adjustment switch 30, the timer setting switch 25, etc. (step 32). Therefore, while this automatic cooking operation is being performed, an input cannot be performed by these operations. However, it is possible to input an automatic cooking operation cancel command by operating the tear switch 31.

  And based on the detection information of the upper side temperature sensor 45 and the lower side temperature sensor 46, it is discriminate | determined whether the temperature in the grill warehouse 32 is abnormal (step 33). More specifically, if either the detection value TH1 of the upper temperature sensor 45 is 320 ° C. or higher or the detection value TH2 of the lower temperature sensor 46 is 220 ° C. or higher, an abnormally high temperature is detected. It is determined that the state is present.

  Next, determination information calculation processing is executed (step 34). This determination information calculation processing will be described based on the flowchart of FIG. 10 and the time chart of FIG. 12. The temperature measurement start time e as the set time has elapsed after the ignition to the grill burner 2 is detected and the ignition state is detected. When the measured start time is reached, the detection value TH1 of the upper temperature sensor 45 at that time is detected as the first detection value TA2, and the detection value TH2 of the lower temperature sensor 46 is detected as the first detection value TB2. (Steps 100 and 101). When the measurement end time f when the temperature measurement end time f has elapsed since the ignition to the grill burner 2 was detected, that is, when the measurement end time has elapsed from the measurement start time, the upper side temperature The detection value TH1 of the sensor 45 is detected as the second detection value TA1, and the detection value TH2 of the lower temperature sensor 46 is detected as the second detection value TB1 (steps 102 and 103). However, the detected value TH1 of the upper temperature sensor 45 is set in advance even if the temperature measurement end time f elapses after the ignition to the grill burner 2 is detected and the ignition state is detected, and the measurement end time is not reached. When the detected upper limit temperature X2u is reached, or when the detected value TH2 of the lower side temperature sensor 46 reaches the preset upper limit temperature X2d, the detected value TH1 of the upper side temperature sensor 45 is set to the second detected value at that time. Detection is performed as TA1, and the detection value TH2 of the lower temperature sensor 46 is detected as the second detection value TB1 (steps 104 and 105).

  As shown in the list of constants in FIGS. 13 to 16, the temperature measurement start time e is always set to a constant value (100 seconds) even when the cooking menu or baking is changed. As the end time f, different values are set according to the set cooking menu and the difference in cooking. In addition, the upper limit temperature X2u is set to a substantially constant temperature, for example, 400 ° C. regardless of the cooking menu, and the upper limit temperature X2d is set to a different value depending on the cooking menu to be set and the difference in cooking. The

When the first detection values TA2 and TB2 and the second detection values TA1 and TB1 as described above are detected, information for determination is calculated using each data (step 106). More specifically, the first detection value TA2 is subtracted from the second detection value TA1 to obtain a temperature increase amount ΔUt based on the detection information of the upper temperature sensor 45, and the first detection value TB2 is subtracted from the second detection value TB1. Then, the temperature increase amount ΔDt based on the detection information of the lower temperature sensor 46 is obtained.
Therefore, in this embodiment, the time obtained by subtracting the temperature measurement start time e from the temperature measurement end time f corresponds to the measurement elapsed time.

  Next, the correction temperature rise amount Δt is obtained by the following formula 1. However, ΔDt = TB1-TB2, ΔUt = TA1-TA2, and Δt is set to 1 if the calculation result is smaller than “1”. That is, the minimum value of the correction temperature rise amount Δt is 1. A and B are coefficients set in advance based on experimental data, and various different values are set according to the difference in the cooking menu and baking, the difference in initial ignition temperature THBO, and the like ( FIG. 13 to FIG. 16).

[Equation 1]
Δt = ΔDt−A × ΔUt−B

  When the description is made with reference to FIG. 18, the corrected temperature increase amount (A × ΔUt) is obtained by multiplying the temperature increase amount (ΔUt) detected by the upper side temperature sensor 45 by a preset coefficient (A). Then, the corrected temperature rise amount (Δt) is obtained by subtracting the corrected temperature rise amount (A × ΔUt) from the temperature rise amount (ΔDt) detected by the lower temperature sensor 46. The actual measured value is obtained as a fixed value determined at one point on each line shown in FIG. 18 when the heat capacity of the object N to be heated is determined. As can be seen from FIG. 18, the corrected temperature increase amount (Δt) is obtained as a value that decreases as the heat capacity increases in both the small heat capacity range P1 and the large heat capacity range P2.

  Next, the corrected temperature rise amount Δt is substituted into the following formula 2 to calculate virtual load amount information Fg corresponding to the load amount of the object to be heated. However, C and D are coefficients set in advance based on experimental data, and different values are set in accordance with the set cooking menu, the difference in cooking, the difference in ignition initial temperature THBO, and the like ( FIG. 13 to FIG. 16). Further, when the temperature measurement end time f has elapsed in step 102, F = f, and even if the temperature measurement end time f has not elapsed in step 102, the detection value TH1 of the upper temperature sensor is the upper limit temperature. When X2u is reached, or when the detection value TH2 of the lower temperature sensor reaches the upper limit temperature X2d, if the elapsed time up to that point is f ′, then F = f ′. FIG. 12 shows a state where the temperature measurement end time f has elapsed in step 102.

  That is, as described above, the correction temperature increase amount Δt is obtained as a value that decreases the temperature increase amount as the heat capacity increases in both the small heat capacity range and the large heat capacity range. The virtual load amount information Fg corresponding to the heat capacity of the object to be heated can be calculated from the arithmetic expression using the increase amount Δt.

[Equation 2]
Fg = (C × (F−e) / Δt + D) / 10

  Next, the heating time Tx for cooking from the start of heating using the virtual load amount information Fg and the following equation 3 to the end of cooking heating for the object to be heated is obtained, and further, the following equation 4 is used. The heating amount switching that is the elapsed time from when the ignition to the grill burner 2 is performed and the ignition state is detected until the switching timing for switching the heating amount of the grill burner 2 from the initially set heating amount to the lower low heating amount is reached Time Ty is obtained. However, i and j are coefficients set in advance based on experimental data, and different values are used depending on the set cooking menu and the difference in cooking. E is a coefficient set in advance based on experimental data, but various values are set depending on the cooking menu, the difference in cooking, the difference in initial ignition temperature THBO, and the like ( FIG. 13 to FIG. 16). When the cooking heating time Tx exceeds a predetermined maximum combustion time Txmax, the cooking heating time Tx is set to the maximum combustion time Txmax.

[Equation 3]
Tx = Fg × i / 1000 + j

[Equation 4]
Ty = E × Tx

  If each of the data TA1, TA2, TB1, TB2 is not detected and the takeover switch 51 is operated to cancel the automatic cooking operation, the input suppression state is canceled and the manual cooking operation is started ( Steps 107 and 108). When there is no cancel command and fire extinguishing is commanded by operating the point fire switch 32, the input suppression state is canceled and the fire extinguishing process is executed, and then the process returns to step 2 (steps 109 and 110). In the temperature abnormality determination process, a temperature abnormality has occurred. Specifically, the detected value TH1 of the upper temperature sensor 37 is 320 ° C. or higher, and the detected value TH2 of the lower temperature sensor 38 is 220 ° C. If any of the above is detected, after performing the fire extinguishing process, the buzzer BZ is sounded and notified, and the combustion lamp 24 blinks 10 times, and then the process ends (steps 111 to 114). At this time, since it is in an abnormal state as described above, the interlock state is entered, and subsequent processing is not accepted.

  Next, the remaining heating time until the heating of the article N to be heated is set based on the cooking heating time Tx obtained as described above (step 35). This remaining heating time is a time obtained by subtracting the elapsed time from when the ignition to the grill burner 2 is detected to the present time from the cooking heating time Tx. Therefore, the remaining heating time is counted down with the passage of time and gradually becomes shorter, and this remaining heating time is displayed on the timer display unit 26 (step 36). FIG. 11B shows that the remaining heating time displayed on the timer display unit 26 is “5 minutes”.

  Thereafter, when the detected value TH1 of the upper side temperature sensor 45 reaches the upper limit temperature X2u, the detected value TH2 of the lower side temperature sensor 46 reaches the upper limit temperature X2d, and the ignition to the grill burner 2 is performed and the ignition state is detected. If at least one of the conditions that the heating amount switching time Ty elapses after that is satisfied, a thermal power switching process for reducing and adjusting the thermal power of the grill burner 2 is performed (steps 37 and 38). In other words, even when the detection value TH1 of the upper temperature sensor 45 and the detection value TH2 of the lower temperature sensor 46 do not rise to the preset upper limit temperature, the low value is detected when the heating amount switching time Ty elapses. As an example of the heating amount, the upper and lower burners 2a and 2c and the lower burners 2b and 2c are provided with opening / closing provided in each of the branch passages branched into a branch passage for the upper burner and a branch passage for the lower burner, so Both the solenoid valves 16 are switched to the closed state. In this way, when the heating amount switching time Ty elapses, the heating amount is set to a low value to prevent the object to be heated N from being burnt and to have a good baking condition.

  Further, when the timer time set as the time until the cooking heating time Tx ends and the timer counts up, the fire extinguishing process of the grill burner 2 is executed (steps 39 and 40). That is, the original solenoid valve 12 and the flow rate control valve 18 are closed, and the thermal power display and the combustion lamp 24 are turned off. In addition, the buzzer BZ is sounded to notify that “00” displayed on the timer display unit 26 is blinked 10 times, and then the process returns to Step 2 (Steps 41 and 42). FIG. 11C shows the display state at this time.

  If cancellation of the automatic cooking operation is instructed by operating the take-off switch 31 until the timer counts up, the input suppression state is canceled and the process proceeds to manual cooking operation (steps 43 and 44). After shifting to the manual cooking operation, a heating power switching command by operating the thermal power switching switch 27, an increase / decrease adjustment of the heating timer time by operating the timer setting switch 25, and the like can be performed.

  If the timer does not count up and the fire extinguishing switch 23 is turned on and fire extinguishing is instructed without the operation of the take-off switch 31, the fire extinguishing process as described above is executed and the process returns to step 2 (step 45, 46). If a temperature abnormality has occurred in the temperature abnormality determination process, the fire extinguishing process is executed, then the buzzer BZ is sounded and notified, and the combustion lamp 24 is blinked 10 times (steps 47 to 50). ).

  In FIG. 17, the time of the detected values of the upper temperature sensor 45 and the lower temperature sensor 46 in the state where five round horse mackerels are set as the objects to be heated, “cooking” is set as the cooking menu, and “strong” is set as the baking level. The actual measurement data which this applicant measured about the change accompanying progress are shown. That is, the measurement result of the upper side temperature sensor 45 is indicated by a solid line, and the measurement result of the lower side temperature sensor 46 is indicated by a broken line. A list of constants used at that time is shown in FIG. Incidentally, this data is data when the ignition initial temperature THBO is 31 ° C.

  The temperature detection data in the actual measurement data are TB2 = 35 ° C., TB1 = 64 ° C., TA2 = 53 ° C., TA1 = 139 ° C. And it will be as follows when it calculates using the various constants described in FIG.

Δt = ΔDt−A × ΔUt−B
= (64-35) -0.2333 × (139-53)-(-13.998)
= 22.9342

Fg = (C × (F−e) / Δt + D) / 10
= (978 × (350-100) /22.9342+219) / 10
= 1088

Tx = Fg × i / 1000 + j
= 1088 × 810/1000 + 320
= 1201 (seconds) = 20 (minutes) 1 (seconds)

Ty = E × Tx
= 0.79495 × 1201
= 955 (seconds) = 15 (minutes) 55 (seconds)

  As shown in FIGS. 13 to 16, the various constants used in the various arithmetic expressions described above are set by the applicant based on experimental data and the like. , And a value set according to the difference in ignition initial temperature. Therefore, the plurality of conditions described in FIGS. 13 to 16 correspond to the plurality of calculation conditions to be selected according to the cooking menu. However, the numerical values shown in these drawings are merely examples, and the present invention is not limited to these numerical values.

  The installation positions of the upper side temperature sensor 45 and the lower side temperature sensor 46 are not limited to the above-described positions, and the small heat capacity range in which the heat capacity is small in the predicted heat capacity variation range of the object N to be heated. In the large heat capacity range, the rate of change of the temperature increase with respect to the change of the heat capacity of the object to be heated N is the same or substantially the same, and the heat capacity of the object to be heated N increases as the heat capacity of the object to be heated N decreases. If the rate of change of the temperature increase amount with respect to the change in the heat capacity of the object to be heated N is different from each other, the temperature increase amount increases as the heat capacity of the object to be heated N increases. What is necessary is just to change an installation position suitably.

[Another embodiment]
Hereinafter, other embodiments are listed.

(1) In the above-described embodiment, the control means raises one of the temperature rise amounts detected by the upper temperature sensor 45 and the lower temperature sensor 46 as a pair of temperature detection units. A correction temperature increase amount obtained by subtracting the other temperature increase amount by a preset coefficient from the amount to obtain a corrected temperature increase amount, and the cooking heating time is determined based on the corrected temperature increase amount; However, the present invention is not limited to such a configuration. For example, the heat capacity of the object to be heated at this time is in a large range or a small range by comparing the amounts of temperature rise detected by the pair of temperature detection units. The cooking heating time may be determined from the result of the determination and either one of the temperature rises, and various other calculation methods can be used.

(2) In the above embodiment, the upper side temperature sensor 45 and the lower side temperature sensor 46 as the pair of temperature detection units start heating by the grill burner even if the heat capacity of the object to be heated is the same. Exemplified are those in which the amount of temperature increase during the elapsed time for measurement from the measurement start time to the measurement end time after the elapse of time is provided at different positions.
