Description

The present invention relates to a double-sided cooking cooker capable of heating foods on both the upper and lower sides at the same time.

Conventionally, it is equipped with a platen that can be opened and closed by swirling in the vertical direction with respect to the griddle, and foodstuffs such as hamburger putty, steak meat, and hamburger are placed up and down by the hot plate on the upper surface of the griddle and the hot plate on the lower surface of the platen. In a double-sided baking cooker that can heat both sides at the same time by sandwiching it from the top, the user determines the distance between the upper and lower hot plates when the platen is in the closed position, that is, the height position of the platen with respect to the griddle. It is known that the configuration can be arbitrarily set within (see, for example, Patent Documents 1 and 2).

Japanese Unexamined Patent Publication No. 10-309236 Japanese Unexamined Patent Publication No. 10-323286

However, in the conventional double-sided baking cooker, it is necessary for the user to determine the platen height based on his / her own experience, cooking instructions, etc., and set it manually according to the ingredients to be cooked. Depending on the skill level, the interval between the hot plates may differ, or a setting error may occur, so that there is a risk that the degree of baking may vary between the upper surface side and the lower surface side of the food. In addition, it is troublesome to check and adjust the platen height setting every time the type of food to be cooked changes.

Further, in the conventional double-sided cooking cooker, a hot plate temperature sensor for detecting the temperature of the hot plate is generally provided at a substantially central position on the back surface side of each hot plate, and the hot plate is maintained at a set cooking temperature. It is configured to control the on / off of the hot plate heater based on the detection temperature of the hot plate temperature sensor. Therefore, especially when the food is cooked from the frozen state, if the frozen food is placed at the substantially center position of the hot plate, the temperature of the food is directly transmitted to the hot plate temperature sensor, and the detection temperature is significantly lowered. .. As a result, the hot plate heater is kept on until the detected temperature returns to the set cooking temperature. Therefore, even if the platen height is set to a height suitable for the food, the food is excessive. There was a risk that it would not be finished properly due to being heated by.

The present invention has been made in view of the above problems, and an object of the present invention is to provide cooking performance and convenience in a double-sided baking cooker capable of simultaneously heating foodstuffs on both the upper and lower sides with a hot plate on the griddle side and a hot plate on the platen side. The purpose is to improve the sex.

The double-sided cooking cooker according to the present invention includes a griddle having a hot plate on the upper surface portion and a platen having a hot plate on the lower surface portion and being supported so as to be swiveled in the vertical direction with respect to the griddle and can be opened and closed. A double-sided cooking cooker that can heat both sides at the same time by sandwiching food from above and below with both hot plates. A hot plate heater that heats each hot plate and a hot plate temperature sensor that detects the temperature of each hot plate. A heating control unit that turns each hot plate heater on and off based on the detection temperature of each hot plate temperature sensor, a platen drive unit that drives the opening and closing of the platen, and a height sensor that detects the height position of the platen with respect to the griddle. Equipped with an operation panel for setting and instructing operating conditions such as the type of food to be cooked and the cooking temperature, and a storage unit for storing the set height of the platen for each type of food, the type of food selected and operated on the operation panel can be selected. At the same time, the height position of the platen during cooking detected by the height sensor is automatically adjusted to the set height corresponding to the selected foodstuff.
In the temperature control state in which the corresponding hot plate heater is turned on and off between the predetermined heater off temperature and the heater on temperature so that the hot plate is maintained at the set cooking temperature, the detection temperature of the hot plate temperature sensor is lower than the heater off temperature and heat is generated. When cooking is started when the plate heater is off and the detected temperature drops to a predetermined first complementary judgment temperature lower than the heater on temperature.
When the detection temperature rises to a predetermined complement off temperature that is higher than the first complement judgment temperature and lower than the heater off temperature, the corresponding hot plate heater is turned off.
After turning off the hot plate heater, the detected temperature is higher than the complement-off temperature, at the time of the rise to a predetermined complementary on temperature lower than the heater on the temperature, the corresponding hot plate heater is characterized in ounces Rukoto.

According to this, if the type of food to be cooked is selected on the operation panel, the height position of the platen during cooking is automatically adjusted to the set height corresponding to the type of the selected food. Even if the skill level is different, it is possible to cook at hot plate intervals suitable for the type of ingredients. Therefore, it is unlikely that the degree of baking varies between the upper surface side and the lower surface side of the food. It also saves the trouble of checking and adjusting the height position of the platen each time the type of food to be cooked changes.
Further, when the foodstuff is cooked from the frozen state, as a result of the foodstuff being arranged at the arrangement position of the hot plate temperature sensor on the hot plate, the detected temperature is much lower than the heater on temperature and reaches the first complementary determination temperature. In this case, since the hot plate heater is turned off without waiting for the detection temperature to rise to the heater off temperature, it is possible to prevent the food from being overheated. Therefore, the degree of baking is less likely to vary.

Further, the double-sided cooking cooker according to the present invention has a griddle having a hot plate on the upper surface portion and a platen having a hot plate on the lower surface portion and being supported by swirling in the vertical direction with respect to the griddle so as to be openable and closable. It is a double-sided cooking cooker that can heat both sides at the same time by sandwiching food from above and below with both hot plates. A hot plate heater that heats each hot plate and a hot plate that detects the temperature of each hot plate. A temperature sensor, a heating control unit that turns each hot plate heater on and off based on the detection temperature of each hot plate temperature sensor, a platen drive unit that opens and closes the platen, and a height sensor that detects the height position of the platen with respect to the griddle. It is equipped with an operation panel for setting and instructing operating conditions such as the type of food to be cooked and the cooking temperature, and a storage unit for storing the set height of the platen for each type of food, and the food selected and operated on the operation panel. The height position of the platen during cooking detected by the height sensor is automatically adjusted to the set height corresponding to the selected foodstuff according to the type.
In a temperature control state in which the corresponding hot plate heater is turned on and off between a predetermined heater off temperature and the heater on temperature so that the hot plate is maintained at the set cooking temperature, the temperature detected by the heat medium temperature sensor is equal to or higher than the heater off temperature. When cooking is started when the plate heater is off, the detected temperature is lower than the heater on temperature, and the temperature drops to the second complementary judgment temperature, which is a predetermined temperature less than the start temperature of cooking.
When the detection temperature rises to a predetermined complement off temperature that is higher than the second complement judgment temperature and lower than the heater off temperature, the corresponding hot plate heater is turned off.
After turning off the hot plate heater, the corresponding hot plate heater is turned on when the detected temperature rises to a predetermined complementary on temperature lower than the complementary off temperature and lower than the heater on temperature.

According to this, when the foodstuff is cooked from the frozen state, as a result of the foodstuff being arranged at the arrangement position of the hot plate temperature sensor on the hot plate, the detected temperature is lower than the heater-on temperature and is predetermined from the cooking start temperature. When the temperature drops, the hot plate heater is turned off without waiting for the detection temperature to rise to the heater off temperature, so that it is possible to prevent the food from being overheated. Therefore, the degree of baking is less likely to vary.

In each of the above double-sided baking cookers, the height position of the platen during cooking can be automatically adjusted according to the elapsed time from the time when cooking is started and the platen closing operation is stopped. preferable. According to this, even if the thickness of the food material changes during cooking, the height position of the platen can be automatically changed according to the elapsed time, so that cooking can be performed at hot plate intervals suitable for the thickness of the food material. Therefore, it is less likely that the degree of baking varies between the upper surface side and the lower surface side of the food. In addition, it is possible to save the trouble of manually adjusting the height position of the platen according to the change in the thickness of the ingredients during cooking.

In the double-sided baked cooker, the heater off temperature, the heater on the temperature, complement-off temperature, and any complementary on temperature, it is preferred that the settable by different between griddle side and the platen side. By setting the heater off temperature, heater on temperature, complementary off temperature, and complementary on temperature differently on the griddle side and the platen side in this way, both the upper and lower sides of the food can be heated appropriately. Is less likely to vary.

As described above, according to the present invention, even if the skill level of the user is different, the degree of baking of the ingredients is unlikely to vary, and the cooking performance is remarkably improved. In addition, it is not necessary to check or adjust the height position of the platen every time the type of food is changed, which greatly improves convenience.

The height sensor 34 is connected and supported so as to be vertically movable in the vertical direction with respect to the actuator 35, and the platen detector 134 that descends together with the support shaft 130 is detected by the height sensor 34 during the operation of closing the platen 12. The position is detected as the height position of the platen 12 with respect to the griddle 11. The platen detector 134 may be provided on the support shaft 130, the hinge 131, or the frame of the drive chain 32 as long as it can serve as a reference for indicating the height position of the platen 12. It may be provided in the engaging portion 320.

The actuator 35 is provided with a sensor detector 136 which is connected and supported together with the height sensor 34 so as to be vertically movable in the vertical direction and indicates the arrangement height of the height sensor 34 in the griddle 11. Further, the opening / closing mechanism unit 13 includes an origin sensor 36S that detects whether or not the sensor detector 136 is at a predetermined detection position that is the origin position, and a predetermined value that is higher than the origin position where the sensor detector 136 is the upper limit position. The upper limit sensor 36H for detecting whether or not the sensor is in the detection position of the above, and the lower limit sensor 36L for detecting whether or not the sensor detector 136 is in a predetermined detection position lower than the origin position which is the lower limit position are provided. Before starting the closing operation of the platen 12, the height sensor 34 is moved up and down by the actuator 35, and the position detected by the sensor detector 136 by the origin sensor 36S is set by the origin position, the upper limit sensor 36H and the lower limit sensor 36L. The detected positions are set as the upper limit position and the lower limit position, respectively, and the sensor position correction operation for matching the operation of the actuator 35 with the position of the height sensor 34 is performed.

The power switch 20A, cooking switch 20B, standby mode switch 20C, operation cancel switch 20D, operation panel 20E, hot plate heaters 21 and 22, hot plate temperature sensors 23 and 24, open / close motor 30, height sensor 34, actuator 35, The origin sensor 36S, the upper limit sensor 36H, and the lower limit sensor 36L are all connected to the control circuit 100 incorporated inside the griddle 11 through electrical wiring (not shown).

The control circuit 100 includes a power supply control unit that controls the on / off of the main power supply of the double-sided cooking cooker 1, a heating control unit that controls the temperatures of the lower heating plate 14 and the upper heating plate 15, and an opening / closing control that controls the opening / closing operation of the platen 12. The height control unit that adjusts the height position of the height sensor 34, the operation display control unit that controls the operation of the operation panel 20E, the set height, set cooking temperature, set cooking time, etc. of the platen 12 for each type of food. It has a circuit configuration such as a storage unit for storing the operating conditions of the above and a time measuring unit for measuring the cooking time, and the operation of the entire double-sided cooking cooker 1 is controlled by each of these control units, the storage unit, and the timing unit.

The operation control of the double-sided baking cooker 1 by the control circuit 100 will be described in detail. First, when the main power supply is turned on by the power switch 20A and the main power supply of the double-sided cooking cooker 1 is turned on, the operation display control unit displays the display screen of the operation panel 20E as shown in FIG. , A plurality of food selection keys 41 serving as pseudo operation switches for selecting the type of food to be cooked, and a plurality of display switching keys 42 serving as pseudo operation switches for switching the food selection keys 41 to be displayed. Set to "Menu screen".

The foodstuff selection key 41 is individually assigned operating conditions such as the set height of the platen 12, the set cooking temperature Ts, and the set cooking time. Although not shown, the operation panel 20E is switched to the "setting screen". By operating various setting operation keys displayed on the setting screen, it is possible to arbitrarily change the setting of the operating conditions assigned to each food ingredient selection key 41. At that time, the set cooking temperature Ts can be set to different values on the griddle 11 side and the platen 12 side.

When the operation cancel switch 20D is pressed after the main power is turned on, the open / close control unit operates the open / close motor 30 to open the platen 12 to a predetermined open position. Further, after correcting the operation of the height sensor 34, the height control unit moves the height sensor 34 to a predetermined start position and puts it in the activated state.

When one ingredient selection key 41 is touch-operated on the operation panel 20E after the activated state is reached, the operation display control unit selects the display screen of the operation panel 20E as shown in FIG. Ingredient information 43 indicating the type of ingredient, remaining time information 44 indicating the set cooking time before the start of cooking and the remaining cooking time after the start of cooking, operation information 45 indicating the current operating state, and a menu screen or setting screen. The "information display screen" is set to display a plurality of screen switching keys 46 that serve as pseudo operation switches for switching to.

Further, the height control unit operates the actuator 35 to move the height sensor 34 to a height position corresponding to the set height of the platen 12. In the heating control unit, both hot plate heaters 21 and 22 are turned on while the platen 12 is open, and the detection temperatures T1 and T2 of the hot plate temperature sensors 23 and 24 are set to the set cooking temperature Ts, respectively. The lower hot plate 14 and the upper hot plate 15 are heated until they reach the temperature.

Further, the operation display control unit displays the operation information 45 of the operation panel 20E as "heating", and the backlight of the operation panel 20E is a color indicating that the temperature is being raised (for example, yellow). ) To make it blink.

If the display switching key 42 is touch-operated before any of the food selection keys 41 is touch-operated, the operation display control unit replaces the displayed food selection key 41 with another food ingredient. The food selection key 41 corresponding to the type is displayed on the operation panel 20E. The user finds and operates the foodstuff selection key 41 corresponding to the foodstuff to be cooked from the plurality of foodstuff selection keys 41 sequentially displayed in this way.

If the detection temperatures T1 and T2 of the hot plate temperature sensors 23 and 24 reach the set cooking temperature Ts in the state of being heated, the heating control unit keeps the platen 12 open and lowers the hot plate. Each of the hot plate heaters 21 and 22 is individually turned on and off between a predetermined heater off temperature Ta and a heater on temperature Tb lower than the heater off temperature Ta so that 14 and the upper heating plate 15 are maintained at the set cooking temperature Ts. It shifts to the temperature control mode, that is, the state where it can be fired.

When the set cooking temperature Ts is set to different values on the griddle 11 side and the platen 12 side, the heater off temperature Ta and the heater on temperature Tb are also set on the griddle 11 side and the platen 12 side according to the set cooking temperature Ts. Set to a different value.

Further, when the firing is possible state as described above, the operation display control unit displays the operation information 45 of the operation panel 20E as "firing possible" and sets the backlight of the operation panel 20E in the firing possible state. It is lit with a color indicating that it is present (for example, green).

When the standby mode switch 20C is pressed to instruct the start of the standby mode when the firing is possible, the open / close control unit is at a height position where the platen detector 134 is detected by the height sensor 34. The platen 12 is closed until the platen 12 is closed, and the heating control unit turns on and off the hot plate heaters 21 and 22 so that the lower hot plate 14 and the upper hot plate 15 are maintained at the set cooking temperature Ts, as in the state in which firing is possible. Adjust mode, that is, heat retention state. Further, the operation display control unit displays the operation information 45 of the operation panel 20E as "standby" and blinks the backlight of the operation panel 20E with a color (for example, green) indicating that the heat is retained. Make it in the state of being made. After that, when the operation cancel switch 20D is pressed and the standby mode is instructed to stop, the process returns to the firing capable state again.

When the cooking switch 20B is pressed to instruct the start of cooking in the state where baking is possible, the open / close control unit closes the platen 12 when the platen detector 134 is detected by the height sensor 34. Is automatically stopped. As a result, the platen 12 is closed to a set height corresponding to the selected type of food. Further, the heating control unit heats each heat so that the lower hot plate 14 and the upper hot plate 15 are maintained at the set cooking temperature Ts until the elapsed time from the start of cooking reaches the set cooking time, as in the case where the baking is possible. The temperature control mode in which the plate heaters 21 and 22 are turned on and off, that is, the state during firing is set.

Further, when the state of firing is reached, the operation display control unit displays the operation information 45 of the operation panel 20E as "baking" and displays the remaining time information 44 according to the elapsed time from the start of cooking. Change sequentially. Further, the backlight of the operation panel 20E is maintained in the same state as the state in which firing is possible.

When the operation cancel switch 20D is pressed to instruct to stop cooking during the baking state, the open / close control unit opens the platen 12 to a predetermined open position. Then, the temperature control of the lower hot plate 14 and the upper hot plate 15 by the heating control unit and the operation control of the operation panel 20E by the operation display control unit are returned to the state in which firing is possible.

By the way, when cooking food from a frozen state, when the food is placed substantially at the center of the upper surface of the lower heat plate 14, the temperature of the food is measured by the heat plate temperature sensors 23 and 24 arranged below and above the food. It is transmitted directly. As a result, as shown in FIGS. 7 and 8, the detection temperatures T1 and T2 of the hot plate temperature sensors 23 and 24 continue to drop for a certain period of time even after the hot plate heaters 21 and 22 are turned on, and the heaters are turned off. It is well below the temperature Ta.

Therefore, as shown in FIG. 7, the heating control unit is instructed to start cooking when the detection temperatures T1 and T2 are lower than the heater off temperature Ta, and the detection temperature T1 is in the firing state. , T2 drops to a predetermined first complement determination temperature Tu lower than the heater on temperature Tb, the detection temperatures T1 and T2 reach a predetermined complement off temperature Tc lower than the heater off temperature Ta and higher than the first complement determination temperature Tu. When the temperature rises, the mode shifts to the first complementary mode A in which the corresponding hot plate heaters 21 and 22 are turned off.

Alternatively, as shown in FIG. 8, when the start of cooking is instructed when the detection temperatures T1 and T2 are equal to or higher than the heater off temperature Ta, the detection temperatures T1 and T2 start cooking when the baking is in progress. When the temperature drops from the start temperature X, which is the temperature at the time, to the second complement determination temperature Tx, which is a predetermined temperature subtracted, the detection temperatures T1 and T2 are lower than the heater off temperature Ta and higher than the second complement determination temperature Tx. When the temperature rises to Tc, the process shifts to the second complementary mode B in which the corresponding hot plate heaters 21 and 22 are turned off.

When the set cooking temperature Ts is set to different values on the griddle 11 side and the platen 12 side, the first complement determination temperature Tu, the complement off temperature Tc, and the second complement determination temperature Tx are also set to the set cooking temperature Ts. In addition, different values are set on the griddle 11 side and the platen 12 side.

Even if the hot plate heaters 21 and 22 are turned off when the temperature of the hot plates 14 and 15 drops significantly as described above and then starts to rise again, the foodstuff continues to be heated by the preheating of the hot plates 14 and 15. However, the amount of heat applied to the food material per unit time during that period is smaller than that when the hot plate heaters 21 and 22 are on. Therefore, as shown in FIGS. 7 and 8, the heating control unit turns off the hot plate heaters 21 and 22 in the complement mode A or the complement mode B, and then the detection temperatures T1 and T2 are higher than the heater on temperature Tb. When the temperature rises to a low predetermined complementary on temperature Td, the corresponding hot plate heaters 21 and 22 are turned on, and the normal temperature control mode is resumed.

If the set cooking temperature Ts is set to a different value on the griddle 11 side and the platen 12 side, the complementary on-temperature Td is also set to a different value on the griddle 11 side and the platen 12 side according to the set cooking temperature Ts. Set.

As described above, according to the double-sided cooking cooker 1, if the type of foodstuff to be cooked is selected on the operation panel 20E, the height position of the platen 12 is set when the platen 12 is closed in response to the instruction to start cooking. Since the height is automatically adjusted to the set height corresponding to the selected food, even if the skill level of the user is different, it is possible to cook at the hot plate interval suitable for the type of food. As a result, the degree of baking is less likely to vary between the upper surface side and the lower surface side of the food, and the cooking performance is remarkably improved. In addition, since it is possible to save the trouble of checking and adjusting the set height of the platen 12 each time the type of food is changed, the convenience is significantly improved.

Moreover, in this product, when the foodstuff is cooked from the frozen state, the foodstuff is placed at a substantially central position on the upper surface of the lower heating plate 14, and as a result, the detection temperatures T1 and T2 of the heating plate temperature sensors 23 and 24 are set. When the heater on temperature Tb is much lower than the first complementary judgment temperature Tu, or when the cooking start temperature X is much lower than the second complementary judgment temperature Tx, the detection temperatures T1 and T2 are again the heater off temperatures. Since the corresponding hot plate heaters 21 and 22 are turned off without waiting for the temperature to rise to Ta, it is possible to prevent the food from being overheated. Therefore, the degree of baking is less likely to vary, and the cooking performance is further improved.

Further, in this case, by adjusting the set cooking temperature Ts different for the griddle 11 side and the platen 12 side, the heater off temperature Ta, the heater on temperature Tb, the complementary off temperature Tc, and the complementary on temperature Td are also set on the griddle 11 side, respectively. Since the values are set differently on the platen 12 side and the platen 12, both the upper and lower sides of the food can be appropriately heated. Therefore, the degree of baking is less likely to vary, and the cooking performance is further improved.

Further, depending on the type of foodstuff, the user may intentionally want to cook the foodstuff with different heating degrees on the upper surface side and the lower surface side, but as described above, the settings are different on the griddle 11 side and the platen 12 side. If the cooking temperature Ts is set, the heater off temperature Ta, the heater on temperature Tb, the complementary off temperature Tc, and the complementary on temperature Td are also set to different values on the griddle 11 side and the platen 12 side according to the set cooking temperature Ts. Therefore, the foodstuff can be finished in a desired heated state. Therefore, the variety of cooking is also improved.

In the above embodiment, the set height of the platen 12 is always kept constant during cooking, but the set height of the platen 12 may be automatically adjusted as a predetermined time elapses. More specifically, the storage unit of the control circuit 100 stores the set height of the platen 12 for each unit time (for example, every 30 seconds) during cooking, and the timekeeping unit is instructed to start cooking. From the time when the closing operation of the platen 12 is automatically stopped, monitoring of whether or not the unit time has elapsed is started. After the start of cooking, the height control unit operates the actuator 35 every time the unit time elapses to move the height sensor 34 to a height position corresponding to the set height of the platen 12 during cooking. The set height of the platen 12 may be adjusted only once during cooking, or may be adjusted a plurality of times during cooking.

In this product, even if the food material expands or contracts during cooking and the thickness changes, the height position of the platen 12 can be automatically adjusted according to the elapsed time, so that heat suitable for the thickness of the food material can be adjusted. Can be cooked at plate intervals. As a result, the degree of baking is less likely to vary between the upper surface side and the lower surface side of the food material, and the cooking performance is further improved. Further, the convenience is further improved because it is possible to save the trouble of manually adjusting the set height of the platen 12 according to the change in the thickness of the food during cooking.

Further, in the above embodiment, the hot plate temperature sensors 23 and 24 are arranged at substantially the center positions on the back surface side of the hot plates 14 and 15, but the overall temperature of the hot plates 14 and 15 can be determined. If it can be detected accurately, the hot plate temperature sensors 23 and 24 may be arranged at positions eccentric to the front and back or left and right from the center position on the back surface side of each of the hot plates 14 and 15.
