Description

  The present invention relates to an electromagnetic induction heating cooker, and more particularly to an electromagnetic induction heating cooker that can operate by controlling the magnitude of the output and the heating time in a heating device.

  Most cooking is dependent on the skill and intuition of the cook, but the management of temperature and time is particularly important. The temperature is directly the temperature of the food, but indirectly it may be the temperature of water, oil, air, steam or a pan or hot plate. In recent years, as automatic temperature control technology has advanced, manualization or automation of cooking has progressed so that anyone can easily cook, and many cooking devices have been developed and used. Most cooking appliances are provided with a temperature sensor that directly measures the indirect temperature as described above, and a predetermined temperature is controlled by a value obtained by the sensor. Of these devices, if the temperature is controlled by a pan or iron plate, the pan or hot plate itself is used for cleaning or for providing food to the predator. It is desirable that the temperature sensor can be separated from the temperature sensor, and various measures have been made for the temperature sensor itself or its surroundings. For example, in Japanese Utility Model Laid-Open No. 3-103040, a heating cooker main body separate from the pan is provided in a movable state and is directly inserted into the oil in the pan when the pan is installed in the heating cooker main body. A type of temperature sensor is disclosed. In addition, although not shown in particular, it is fixedly provided on the heating cooker body separate from the pan and hot plate, and when the pan or hot plate is installed on the heating cooker body, the bottom of the pan or hot plate, etc. Temperature sensors that come into natural contact with the sun have also been widely used.

Japanese Patent No. 3079573 A pan using a magnetic metal material is disclosed. JP, 4-242093, A A pan using a magnetic metal material is indicated. Japanese Utility Model Laid-Open No. 3-103040 A conventional temperature sensor provided separately from a pan is disclosed.

  However, when using such a temperature sensor, there is concern about the reliability and reliability of the contact between the temperature sensor and the pan or hot plate that is the container to be heated, the fear of damage to the temperature sensor, and the handling of the sensor unit. In addition, many problems such as troublesomeness such as cleaning and the like have been accompanied, but the cost has increased due to the structural enlargement, complexity, and complexity of the control program.

  The present invention has been made to solve such problems in the prior art, and not only prevents overheating of the heated container, but also does not use a temperature sensor to maintain a constant cooking temperature. In other words, without directly measuring the temperature of the heated container, it is possible to control the output size and heating time in the heating device for induction heating of the heated container safely and reliably with constant quality heating. An object is to provide a cooking device capable of cooking.

  The present invention has been made to achieve the above object, and a heated container made of a magnetic metal material that is not overheated above a predetermined Curie temperature, and the heated container. An electromagnetic induction heating cooker including a heating device for induction heating, wherein the heating device controls the output size and the heating time in the heating device without directly measuring the temperature of the heated container. It can be operated depending on the situation.

  In the cooking device, the output may be an inverter output current provided in the heating device. Moreover, in this cooking appliance, heating to the heating device may be terminated when the value of the inverter output current reaches a predetermined value smaller than the value of the inverter output current at the predetermined Curie temperature. .

  In the cooking device, an alignment means for aligning the heated container at a predetermined position of the heating device may be provided.

  In the cooking device, a unit may be formed by the heated container and the heating device, and the units may be combined to be freely laid out.

  In the cooking device, the heated container and the heating device may be provided independently of each other, and the heated container and the heating device may be freely movable and transportable. . Thereby, they can be easily removed and cleaned, and the cleaning property is improved.

  The cooker may be a gyoza grill.

  By combining the properties of the heated container such that the maximum temperature can be controlled by itself with a heating device that controls the magnitude of the output and the heating time, without using a temperature sensor that has been used in conventional cookers, In other words, it is possible to provide an electromagnetic induction heating cooker that can perform cooking with a certain quality in a simpler and safer manner than before without directly measuring the temperature of the heated container.

  An electromagnetic induction heating cooker according to a preferred embodiment of the present invention will be described below by taking a gyoza grill as an example. Of course, the electromagnetic induction heating cooker according to the present invention is not limited to the gyoza grill shown here, and can also be used as various cookers other than the gyoza grill.

1. Overall Configuration An electromagnetic induction heating cooker according to the present invention includes a heated container such as a pan (shown well in FIG. 1 described later) and a heating device that heats the heated container under constant control (described later). 2 to 4 etc.). The lid of the heated container may or may not have a lid. However, since the gyoza-yaki illustrated here assumes the gyoza-yaki for grilled gyoza especially among gyoza-yaki, it is what provided the container lid.

2. Fig. 1 is a schematic perspective view of a pan and a lid used in the electromagnetic induction heating cooker according to the present invention. The pan 10 and the lid 20 are completely independent from each other or from other parts.

  In actual use, the lid 20 is placed on the pan 10 (shown well in FIG. 5 described later). At this time, since the lid 20 is merely placed on the pan 10, it is easy to separate them. Pans and lids that are commonly used in conventional gyoza-yaki are pivotally provided using hinges (not shown) etc., but they are completely fixed to each other, It cannot be made mutually independent like the pan and lid of this invention. As a result, conventional pans and lids tend to accumulate dirt, but cannot be easily cleaned, for example, cannot be cleaned with a sink. On the other hand, the pan 10 and the lid 20 used in the present invention can be freely carried and used in the same manner as general pans and lids. Therefore, for example, it is possible to wash with a general sink or a dishwasher, and it is also easy to throw away excess water in the pan during cooking of the dumplings. The degree of baking can also be improved. In addition, in the gyoza grill of the present invention, the pan and the lid may be pivotally mounted using a hinge or the like, as in the conventional gyoza grill, but at least during cleaning, they are easily removed and washed. Shall be able to.

  The size of the pan 10 and the lid 20 may be suitable for baking one serving of dumplings, that is, about six dumplings, for example. Therefore, according to the cooking device of the present invention, a necessary amount of food can be cooked with minimum energy, for example, electric power. Moreover, even if it is single item cooking, use of excess energy and discharge | release of a heat | fever can be prevented.

  As described above, in the present embodiment, a dumpling grill for grilled dumplings is particularly assumed. For this reason, the pan 10 has a certain depth so that a certain amount of water can be stored. More specifically, both walls extending from the bottom 11 to the outside of both ends of the pan 10 are formed as inclined portions 12 and 13 having an inclination angle of, for example, about 130 ° upward. Correspondingly, outer inclined portions 22 and 23 having similar inclination angles are formed at both ends of the lid 20, and furthermore, the inner inclination of these outer inclined portions 22 and 23 has similar inclination angles. Inner inclined portions 24 and 25 that are directed downward are formed. As a result, the outer inclined portion 22, the inner inclined portion 24, the outer inclined portion 23, and the inner inclined portion 25 respectively form V-shaped protruding portions 26, 27 as a whole.

  When the pan 20 is covered with the lid 20, the outer inclined portions 22, 23 of the lid 20 and the inclined portions 12, 13 of the pan 10 are relatively overlapped with each other (shown well in FIG. 5 described later). ) For this reason, the steam generated in the space between the pan 10 and the lid 20 during cooking is transmitted as water droplets along the inner walls of the inner inclined portions 24, 25 of the lid from the vicinity of the V-shaped projections 26, 27 to the bottom of the pan 10. Will be returned to. Therefore, according to these pans 10 and lids 20, there is little risk of water drops, oil, etc. leaking out of the pan.

  Here, a magnetic metal material, particularly a magnetic shunt alloy is used as the material of the pot 10. By using a magnetic shunt alloy, the pan itself can control its maximum temperature by itself. As described in Japanese Patent No. 3079573, Japanese Patent Laid-Open No. 4-242093, and the like, a pan made of a magnetic shunt alloy has an eddy current applied to the pan by magnetic lines generated by induction heating means such as an induction heating coil. However, since the magnetism of the pan is lost above the Curie temperature, no eddy current is generated, and therefore the pan is not overheated above the predetermined temperature. As a result, according to the cooking device of the present invention, there is no danger such as ignition of oil, damage due to emptying of the pan, red heat, fire and the like. Furthermore, by using the pan 10, there is no need to provide a temperature sensor in the heating device, work is not hindered due to a failure of the temperature controller, etc., and there is no need to provide a program that responds to temperature changes in the pan. Since it disappears, it is not necessary to reflect the detection result by the temperature sensor in the software configuration. In this way, if a pan made of a magnetic shunt alloy is used, it becomes possible to perform cooking by controlling only the output size and the heating time in the heating device without directly measuring the temperature of the heated container. Thus, cooking can be performed safely and reliably with a simpler structure than before. In addition, the Curie temperature of the pan 10 can be freely set in the vicinity of the cooking temperature corresponding to each heated object for each pan. For example, if it is a pot (even if it is an iron plate) used for grilled products such as beef steak, it is about 250 to 280 ° C., and if it is a pot used for dumplings, pancakes, okonomiyaki, etc., 200 to If it is a pan used for fried food or a hamburger at about 230 ° C, set it around 180 ° C, or about 130-150 ° C if it is a pan used for egg dishes such as steamed food, egg binding and omelet. Will be. However, the Curie temperature once set cannot be changed, and therefore, these pans are used as dedicated pans for a specific object to be heated.

3. 2. Heating device Next, with reference to FIG. 2 thru | or FIG. 5, the heating device used for the heating cooker of this invention is demonstrated. FIG. 2 is a perspective view of the heating device, and further shows a state in which a pan and a lid are placed on the heating device in a schematic side view. FIG. 3 is a method similar to FIG. FIG. 4 shows a modification of FIG. 2 in a slightly different manner from FIG. 2, more specifically, with the lid omitted and shown in a schematic perspective view instead of a schematic side view, FIG. 5 is a diagram for explaining a special method for removing the pan, corresponding to the embodiment of FIG. 4.

  In order to perform electromagnetic induction heating, the heating device 30 is provided with an IH inverter and a coil (not shown). By using an IH inverter or the like, energy saving can be realized, and since the exhaust gas is not discharged, the environment can be improved. The heating device 30 can be controlled by operating various switches 34, lamps 36, and the like on the operation panel 32 provided at the front of the heating device. The switches include, for example, a selection key, a power key, a preheat key, a start key, and the like.

  In the conventional gyoza grill, since the pan and the heating device were provided in a completely fixed state, dirt was easily accumulated between the pan and the heating device, and the cleanability was low. On the other hand, in the dumpling baking apparatus of the present invention, the heating device 30 and the pan 10 (and the lid 20) are provided and fixed in a state of being completely independent from each other, similarly to the relationship between the pan 10 and the lid 20. Not. Furthermore, the pan 10 is merely placed on the top surface 38 of the heating device 30 during cooking, and can be easily removed from the heating device 30 and cleaned. Moreover, in the dumpling baking apparatus of the present invention, the heating device 30 itself is not fixed at all to any part, and can be moved and transported freely and easily.

  In order to align the pan 10 with a predetermined position of the top surface 38 of the heating device 30, more specifically, with the heating plate portion where the IH inverter is disposed, various installation examples as described below are conceivable. In addition, when induction-heating a pan like this invention, the positional relationship between an induction heating means and a to-be-heated container is very important.

The embodiment of FIG. 2 shows alignment means formed by providing a step 46 with a concave portion corresponding to the heating plate 40. The pan 10 is placed and aligned so as to fit in the concave portion 42.
The embodiment of FIG. 3 shows alignment means formed by providing four orthogonal protrusions 44 at the four corners of the corresponding portion of the heating plate 40 on the top surface 38. The pan 10 can be placed inside the protruding portions 44 so that the four corner portions 14 of the pan 10 are fitted, and the pan 10 can be aligned with a predetermined position on the top surface 38.
In the embodiment of FIG. 4, as in the embodiment of FIG. 2, the top surface 38 is recessed 42 to provide a step 46 to fix the position of the pan 10. The steps are removed. By removing a part of the step as described above, the pan 10 can be removed from the heating device 30 using, for example, the dedicated removal tool 6 shown in FIG. The removal tool 6 has a shape in which a part near the center of the front end side of the dustpan is projected forward. While holding the handle 72, the tip protrusion 71 of the detaching tool 6 was inserted between the top surface 38 of the heating device 30 and the bottom of the pan through the top stepped portion 48 and lifted in the direction B. Later, by tilting the front side downward, the pan 10 can be slid and accommodated in the wide accommodating portion 73. The removed pan 10 may be provided to the customer as it is, or the food material may be transferred from the pan 10 to the serving plate after the pan 10 is carried to the customer's table.

  Although not clear from the drawings, the size of the IH inverter provided inside the heating device may be as large as necessary for cooking a single meal in accordance with the size of the pan 10 or the lid 20. . By setting it as such a magnitude | size, even if it is an order for one person, cooking can be performed with the minimum energy and discharge | release of excess heat can be prevented. Furthermore, according to the size of the IH inverter for one serving, the heating device 30 may be sized so that one serving of dumplings can be baked. By combining the heating device 30, the pan 10, and the lid 20 of these sizes, for example, a unit for serving dumplings can be configured. This unitization enables various layouts according to the type of industry that uses the heating cooker, the store scale, etc., and can meet a wide range of needs in a wide range of environments. In addition, when the method of arranging a plurality of units in order to increase the size of the heating cooker is employed, there is an advantage that it is easy to perform subsequent maintenance and equipment replacement.

4). Integrated Heating Device The configuration of the integrated heating device will be described with reference to FIG. As shown in these drawings, a plurality of heating devices can be integrated and standardized to increase the size of the heating cooker. In this case, there is an advantage that the cost is lower than that of increasing the size of the unit. In addition, although the shape of the pan 50 and the lid | cover 60 shown in FIG. 6 differs from what was shown in FIG. 1 etc., this difference does not have a substantial meaning.

  For example, in a store where dumplings are frequently ordered, such as a dumpling specialty store, as shown in FIG. 6, a large number of heating devices are integrated into a single heating device (main body) so that many orders can be accommodated. Also good. In the example of FIG. 6, a total of eight pans and lids can be arranged in two stages on the front and rear. Several pans and lids are arranged, but these pans and lids are only used in one integrated heating device, the function of the heating device itself is the same as before, There are several. Therefore, the function of this integrated heating device is exactly the same as that provided for each pan and lid. In order to perform cooking for each pan and lid, an operation panel 51 is provided for each pan and lid. According to such a configuration, as in the case of forming with a unit, for example, it is possible to deal with a single item in a time zone with a small order, and it is possible to obtain an advantage that it is unnecessary to use extra power and generate heat. it can.

  In addition, for example, in a store where orders are moderately entered such as a Chinese restaurant, for example, three heating devices may be integrated in a state of being arranged in parallel to form one main body. Although not particularly illustrated, it may be considered that the rear stage portion in the integrated apparatus shown in FIG. The integrated apparatus used here may be considered to have the same function as that shown in FIG. 6 except that the number and shape of the heating apparatus are different from those shown in FIG. By preparing such an integrated body as a standard product and arranging it on an existing workbench as much as necessary for the convenience of the store, it is possible to use a minimal, space-saving and relatively expensive unit. The heating device can be prepared at a lower cost than when using the. Furthermore, if space is allowed, it can be added as necessary, and there is an advantage that no unnecessary cost is required.

  For example, in a store where a dumpling order is rarely entered, such as a pub or a convenience store, this unit is not an integrated device, but one unit as described above, or 2 as needed. One can be arranged. This type of usage is optimal for industries that offer a wide variety of menus, such as convenience stores and karaoke boxes, although there is no large kitchen space.

5). Control Method FIGS. 7 and 8 illustrate two cooking control methods that can be employed in the gyoza grill according to the present invention. FIG. 7 shows a control method of temperature control type at idle time, and FIG. 8 shows a control method of power OFF type at idle time. In these figures, the horizontal axis indicates time and work content, and the vertical axis indicates the inverter output size and pan temperature. As will be apparent from the following description, only the magnitude of the inverter output and the heating time are controlled to achieve these control methods.

<Temperature control type during idle time>
In the control method of FIG. 7, the inverter output is reduced but not completely zero during the idle time when cooking is not being performed (section “A2” or section “A2 ′” in FIG. 7). The temperature is kept above a certain level, that is, the temperature of the heated container is adjusted to a certain temperature. Thereby, cooking can be started quickly when necessary. The operation flow in this control method will be described in detail below. Although not apparent from the drawings, all operations described below can be performed by switches on the operation panel of the heating device.

  When the power key is pressed, the display on the operation panel is lit, indicating that the power is on. Next, preheating is started by pressing the preheating key, that is, the inverter output is set to full power for 30 to 40 seconds. As a result, the temperature of the pan 10 once rises to the cookable temperature (“A1” section). Thereafter, the inverter output is lowered to a constant output, that is, a low output for the idle time, and the output is held (“A2” section). At this time, the temperature of the pan is held at a temperature slightly lower than the cooking temperature. In this “A2” section, the ready-to-cook lamp is turned on to inform the operator that cooking is possible at any time. The operator can start cooking at any time by pressing the start key while the ready to cook lamp is lit (B section). During actual cooking, before pressing the start key (basically just before pressing the start key), for example, open the lid of the pan, drain oil, add dumplings, manually add water, and then cover again. It will be necessary to work. The cooking time can be displayed on the display unit by, for example, a countdown method. The inverter output during cooking is full power. The end of cooking can be notified to the operator, for example, with a buzzer. At the same time that the buzzer sounds, that is, at the end of the cooking time countdown, the inverter output is reduced to a low output during the idle time. Note that the buzzer sound may be turned off with a cooking start key, for example. Thereafter, the temperature of the pan is kept at a temperature slightly lower than the temperature at which cooking can be performed again (section “A2 ′”).

<Power OFF type during idle time>
In the control method of FIG. 8, the inverter output is completely turned off during the idle time when cooking is not being performed (section “C” in FIG. 8). Therefore, according to this control method, unnecessary electric power and heat can be suppressed. However, in this case, a preheating time of 30 to 40 seconds is required at each cooking. The operation flow will be described in detail below.

  First, the power key is turned on. This operation may be performed any time before cooking. By turning on the power key, the inverter output is set to full power for 30 to 40 seconds, that is, preheating is started (section “A”). At this time, the lamps related to the power key remain off, and the elapsed time is displayed on the display unit in a countdown manner. When the display unit counts 30 to 40 seconds, the display unit blinks (does not count) the set cooking time, for example, and turns on the cooking ready lamp. At this time, the inverter output is kept at full power, unlike the above example in which the output temporarily decreases. Cooking (section “B”) is started by pressing the start key. When the start key is pressed, the display unit starts counting down and the cooking lamp is turned on. Instead, the cooking ready lamp is turned off. The end of cooking is notified by a buzzer sound, for example, as in the above example. At the same time as the buzzer sounds, that is, at the end of the cooking time countdown, the inverter output is automatically turned off (section “C”). Note that the buzzer sound may be turned off with a cooking start key, for example. After that, when the power key is turned on, the above operation is repeated (section “A ′”, section “B ′”).

  As is clear from the above, according to the present invention, the heating device can be effectively controlled without directly measuring the pan temperature by controlling the time and the inverter output. In addition, according to the present invention, once the control program is registered in the heating device, anyone can realize uniform cooking quality reliably and easily by a simple operation such as pressing a button. Therefore, according to the cooking device of the present invention, skill is not required for use.

6). Temperature Control Mechanism Finally, the temperature control mechanism of the heating device will be described with reference to FIGS. 9 and 10. FIG. 9 is a flowchart showing the operation of this temperature control mechanism, and FIG. 10 is a diagram showing the relationship between the pan temperature and the heating device. In FIG. 10, the horizontal axis shows the temperature of the pan (with time), and the vertical axis shows the input power (solid line) supplied to the IH inverter and the resulting output current (dashed line), that is, the coil flows. The state of change of the value of the current and the relative permeability (dotted line) of the pan are also shown. It should be noted that the temperature of the pan is not actually (directly) measured, but only estimated from the relationship with the inverter output current, that is, the current flowing through the coil.

  As explained above, it is assumed that the pan used in the present invention does not rise above a predetermined Curie temperature. However, in practice, the pan temperature may rise to a temperature slightly higher than the predetermined Curie temperature. Therefore, in the present invention, the temperature control mechanism is also provided in the heating device without relying only on the temperature control mechanism by the pan itself, so that the abnormal temperature rise of the pan can be compensated by the heating device. This temperature control mechanism of the heating device is achieved by controlling the inverter output current. Hereinafter, this temperature control mechanism will be described with reference to the drawings.

  In performing the temperature control, the heating device needs to know in advance the “relationship between pan temperature and inverter output current” shown in FIG. Therefore, the following description is based on the premise that this relationship is preinstalled in the heating apparatus as a program.

Heating of the pan is started by turning on the input power of the inverter (ST1 in FIG. 9). When the input power of the inverter is turned on, the value of the input power rises to its maximum value at once. In response to this, the value of the output current of the inverter also rises at a stretch to a predetermined value. The heating device constantly monitors the value of the inverter output current. More specifically, the value of the inverter output current and the value of the inverter output current at the Curie temperature (C) set in advance according to the permeability of the pan, etc. A predetermined value (L ′) (see FIG. 10) slightly lower than (C ′) ”is compared (ST2). The magnetic field lines generated by the inverter output current, that is, the coil current, generate eddy currents in the pan, so that the pan temperature rises, but the pan relative permeability decreases with the pan temperature. As a result, the inverter input power also decreases accordingly, and conversely, the inverter output current increases. Even when the inverter output current increases, heating continues when the value is less than or equal to the value L ′, that is, the input power remains on, while when the value exceeds L ′ In order to prevent the temperature from rising above the Curie temperature, the inverter input power is completely turned off, the inverter output current is set to 0, and heating is stopped (ST3). As a result, the pot temperature rise stops at L and does not exceed the Curie temperature (C). When the inverter input power is turned off (ST3), the elapsed time thereafter is counted (ST4), and when the predetermined time has elapsed, the process returns to ST1 to start heating again, and the above operation is repeated. On the other hand, when the predetermined time has not elapsed, the process returns to ST3, so that heating is stopped. Note that the operations of ST1 to ST4 above are repeated until the heat treatment is completely completed. Thereby, the temperature of a pan is kept substantially constant.
As is apparent, according to the above temperature control mechanism, an abnormal temperature rise of the pan can be effectively prevented not only by the pan itself but also by the heating device. Furthermore, the above temperature control mechanism also helps protect the inverter. This is because the inverter includes a plurality of heat-sensitive members. However, since the temperature control mechanism can suppress the temperature rise of the heating device, these members can be protected from overheating.

  As is clear from the above description, the temperature state of the pan is well reflected in the inverter output current. The temperature control mechanism of the present invention performs heating control of the pan while indirectly measuring the temperature of the pan by paying attention to the change in the inverter output current.

7). Others The electromagnetic induction heating cooker according to the present invention can be applied not only to gyoza grills but also to various cookers such as steak grills and udon stewers. However, for example, when used to bake steak, the heated container may be a flat iron plate instead of a pan having a certain depth as described above, and conversely, for example, used for stewed udon In this case, the heated container may be a bowl having a relatively deep depth, for example.

  The present invention can be applied to various electromagnetic induction heating cookers that can use a heated container made of a magnetic metal material that is not overheated above a predetermined Curie temperature.
