Description

  The present invention relates to a double pan that can be cooked by either an electromagnetic induction heating cooking device (for example, an IH cooking heater) or a microwave heating cooking device (for example, a microwave oven), and an electromagnetic induction heating cooking device for cooking the same.

  Conventionally, this type of double pan and an electromagnetic induction cooking device that heats and cooks the same have invention of a double pan as a pan used for hot water bathing or steam cooking (see, for example, Patent Document 1 and Patent Document 2).

Yusen, where the food in the inner pot is boiled with the heat of the water boiled in the outer pot, is known as a cooking method in which the pot is slowly cooked without scorching. Yusen is a cooking method mainly used in gas stoves, and it is generally said that there is little need for a hot water pot because electromagnetic induction heating cooking equipment with excellent heating control can control low heat.

  However, the conventional double pan is a pan for effectively performing hot water roasting and steam cooking on a gas stove or electromagnetic induction heating cooking appliance, and has a problem that it is not intended for use in a microwave oven. It was.

  In general, when looking at the flow from cooking to eating, there are pans and pans to use when cooking, and there are dishes to serve at the time of meals, when storing in a freezer / refrigerator or reheating in a microwave There are storage containers for use.

  Therefore, a dish is transferred from a pan to a plate and from a plate to a storage container, and each time, a pot, a plate, and a storage container are washed. Inevitably, there are many dishes and storage containers at home.

  By the way, stewed dishes such as oden, curry and stew are often cooked in a pan, placed in a kitchen table, served, and stored in a freezer / refrigerator.

  In this way, it is also seen in soup that the pan, which is a cooking appliance, is used as it is for eating and storing. This can be thought of as an earth-friendly food culture by reducing the use of dishes and storage containers and reducing the resources consumed by dishwashing.

  The present invention considers a pan (including a storage container) that is used when cooking a dish after cooking it, and then storing the leftovers in a refrigerator / refrigerator as they are and reheating them before eating.

  For example, in a house with all-electric appliances, a pan made of a conductor such as iron or stainless steel is usually used to make a stewed dish with an electromagnetic induction cooking device. This is to use so-called induction heating in which lines of magnetic force are generated by an electromagnetic induction heating cooking device, an eddy current is generated in a pan serving as a conductor, and heat is generated by its electrical resistance.

And the stewed dishes left after meals are often stored in the pan in the freezer / refrigerator. The next time you eat, chill and cook again. Here, while there is a method of reheating using an electromagnetic induction cooking device, a microwave oven is often used for thawing and reheating food stored in a refrigerator / refrigerator.

  This is because microwave heating cooking appliances such as microwave ovens irradiate food with microwaves and generate heat due to frictional heat caused by molecular vibrations of food, so it is known that heat efficiency is higher than heating methods that add heat from the outside. Because it is.

  However, when a metal object is put in a microwave oven and heated, sparks fly, so that a container (pot) containing metal cannot be used in the microwave oven.

  That is, it is not easy to reheat the food stored in the pan that can be used in the electromagnetic induction heating cooking appliance with the microwave heating cooking appliance. Most conventional pans and storage containers can only be used with either electromagnetic induction cooking equipment or microwave cooking equipment.

  Therefore, when reheating using a microwave oven, there was an operation of transferring from a metal pan to a heat-resistant storage container such as glass before and after storing in a refrigerator / refrigerator.

  Some pots have been solved by using special materials (ceramics, enamels, etc.) so that they can be used by both, but these are heavier and more expensive than ordinary pots. There was a difficulty of becoming.

  If the pan is simply used for cooking, it is acceptable that it is heavy and expensive, but if the pan is also used as a storage container, the work of putting the pan in and out of the refrigerator is a thing that requires power It becomes.

  In addition, when the pan is used as a storage container, it cannot be used for other cooking, so it is necessary to have a plurality of pans at home, so a light and inexpensive pan is preferable.

  The present invention solves the above-mentioned conventional problems, and can be used in either an electromagnetic induction heating cooking device (for example, IH cooking heater) or a microwave heating cooking device (microwave oven), and realizes an inexpensive pan, It is another object of the present invention to provide an electromagnetic induction heating cooker that heats and cooks the same.

  And it considers that after cooking with an IH cooking heater, it can be stored in the pan as it is in a freezer / refrigerator and reheated using a microwave oven.

  In order to solve the above-mentioned conventional problems, the double pan of the present invention and the electromagnetic induction heating cooking device for cooking the same are an outer pan that can be used for cooking with the electromagnetic induction heating cooking device, and microwave heating cooking. It consists of an inner pan that can be used for cooking with equipment, and when cooking with an electromagnetic induction heating cooking device, the inner pan is placed in the outer pan and the outer pan is heated as a double pan for the cooking of the inner pan. When cooking and cooking with a microwave heating cooking device, the cooked food is cooked only with the inner pot.

  Thereby, after cooking a double pan with an electromagnetic induction heating cooking appliance, it can be reheated using a microwave heating cooking appliance with an inner pan still.

The double induction pan of the present invention and the electromagnetic induction heating cooking device for cooking the same, when cooking with the electromagnetic induction heating cooking appliance, put the inner pan in the outer pan to make a double pan, and heat the outer pan. When cooking the cooking in the inner pot and cooking with the microwave heating cooking equipment, the cooking is heated with the inner pot as it is, so it is reheated using the microwave heating cooking equipment without transferring the container can do.

  1st invention consists of an outer pan which can be used for heating cooking with an electromagnetic induction heating cooking appliance, and an inner pan which can be used for heating cooking with a microwave heating cooking appliance, and when cooking with an electromagnetic induction heating cooking appliance Put the inner pot in the outer pot and heat the outer pot as a double pot to cook the food in the inner pot. When cooking with microwave heating cooking equipment, cook the food only in the inner pot By setting it as a double pan, after cooking the double pan containing the cooking thing with an electromagnetic induction heating cooking appliance, it can be reheated using the microwave heating cooking appliance with an inner pan.

  In the second invention, in particular, when the material of the outer pot of the first invention is a conductive substance and the material of the inner pot is a non-metallic material, when cooking with an electromagnetic induction heating cooking device, the outer pot When cooking with a microwave heating cooking device, it can be heated only in the inner pot.

  In the third invention, in particular, the outer pan and the inner pan of the first invention have different shapes or different dimensions, and when conducting cooking with an electromagnetic induction heating cooking device, the heat transfer between the outer pan and the inner pan is performed. Place the liquid in the outer pan and prevent the liquid from spilling out of the outer pan or prevent the liquid from entering the inner pan, so that the inner pan can be A liquid can be used to increase the heat transfer to the pot, and the liquid can be prevented from boiling and spilling out of the outer pot or entering the inner pot.

  In the fourth aspect of the invention, in particular, the cross section of the outer pot is made circular by making the cross section of the outer pot of the first invention circular, and the cross section of the inner pot is polygonal, so electromagnetic induction heating cooking It is easy to cook with equipment, and because the inner pot has a polygonal cross section, it can be stored and stored in a refrigerator-freezer, or the inside of the microwave cooking equipment can be used effectively.

  In the fifth invention, in particular, the inner pot of the first invention can be divided into a plurality of parts, and the number of inner pots to be cooked by electromagnetic induction cooking equipment or microwave heating cooking equipment can be adjusted according to the amount of the cooked food. By doing this, the size of the inner pot (the number to be used) can be adjusted according to the amount of the cooked product, so there is no need to heat the inner pot more than necessary. In addition, after cooking, the number of inner pots can be reduced according to the amount of food reduced by eating, and the space required for storage and reheating can be reduced.

  The sixth invention is an electromagnetic induction heating cooking device, particularly comprising the inner pot lid for preventing the food in the inner pot from drying in the first invention, and enabling the inner pot to be used as a storage container. After cooking by cooking, the dishes left using the inner pot as a storage container can be stored as it is in a refrigerator or the like.

Taking into account the structure of the double pan, which is said to be rarely used in induction heating cooking equipment, the cooking control of the inner pot is performed because the cooking temperature is controlled from the detected temperature of the inner pot in addition to the detected temperature of the outer pot. Can be boiled firmly through heat.

In particular, the eighth invention comprises an outer pot temperature detecting means for detecting the temperature of the outer pot and an inner pot temperature detecting means for detecting the temperature of the inner pot or the food in the inner pot. When the correlation between the detected temperature of the outer pot and the detected temperature of the inner pot satisfies the predetermined condition, the detection of the outer pot can be performed by using an electromagnetic induction heating cooking device that performs cooking control corresponding to the double pan. When the correlation between the temperature and the detected temperature of the inner pot satisfies the specified condition, the cooking control is performed from the detected temperature of the outer pot and the detected temperature of the inner pot. It can be cooked firmly through heat up to the pot.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 shows an oblique view and a side view of a double pan in a first embodiment of the present invention and a double pan of an electromagnetic induction heating cooking device for cooking by heating.

  In FIG. 1, the double pan is an outer pan 1 that can be used for cooking with an electromagnetic induction cooking device (IH cooking heater, etc.) and an inner pan that can be used for cooking with a microwave heating cooking device (such as a microwave oven). 2. Heat conduction liquid 4 for transferring the heat of cooked food 3, outer pot 1 to inner pot 2, and liquid 4 expanded by heating is prevented from spilling out of outer pot 1 or entering inner pot 2. And a liquid receiver 5 for the purpose.

  About the double pan comprised as mentioned above and the electromagnetic induction heating cooking appliance which cooks it, the operation | movement and an effect | action are demonstrated below.

  First, when cooking the cooking object 3 with the electromagnetic induction heating cooking appliance, the inner pot 2 is put in the outer pot 1 and the outer pot 1 is heated as a double pot to cook the cooking item 3 in the inner pot 2. Do.

  Moreover, when cooking with a microwave heating cooking appliance, the outer pot 1 is removed and the food 3 is cooked with only the inner pot 2.

  Therefore, the material of the outer pot 1 is a conductive substance such as iron or stainless steel, and the material of the inner pot 2 is a non-metallic substance such as heat-resistant glass. Thereby, a lightweight and cheap double pan can be realized.

  When cooking with an electromagnetic induction heating cooking device, in order to efficiently transfer heat from the outer pot 1 to the inner pot 2, the outer pot 1 and the inner pot 2 are almost the same size and contact each other. It is conceivable to increase the area.

  Actually, since the outer pot 1 and the inner pot 2 are made of different materials, it is necessary to consider the difference in coefficient of thermal expansion when heated. Moreover, if it is iron or stainless steel, it is necessary to consider a deformation | transformation by giving an impact during use of the outer pan 1.

  Therefore, when cooking with an electromagnetic induction heating cooking device, the outer pot 1 and the inner pot 2 are placed between the outer pot 1 and the inner pot 2 in order to efficiently transfer heat even in different sizes and shapes. The heat conductive liquid 4 is put so that heat is efficiently transmitted from the outer pot 1 to the inner pot 2 through the liquid 4.

  In order to increase the efficiency, a large amount of liquid 4 can be put and heat can be transferred from the side of the inner pot 2. The liquid 4 may be water or a more efficient liquid.

  The heat conductivity is generally higher in the solid than in the liquid, and instead of the liquid 4, a solid, for example, a heat conductive sheet can be wound around the inner pot 2 and put in the outer pot 1.

  Now, as the outer pot 1 is heated, the liquid 3 may expand and spill out from the outer pot 1. Moreover, the liquid 4 may enter an inner pot. In order to prevent this, a liquid receiver 5 is provided.

  As shown in FIG. 1, the liquid receiver 5 is provided with a hole in the side surface of the outer pot 1 and allows the liquid exceeding the height of the hole to flow in.

  Moreover, the height of the hole provided in the side surface of the outer pot 1 is made lower than the height of the inner pot 2. As described above, the liquid receiver 5 temporarily stores the thermally expanded liquid, and is not limited to the configuration shown in FIG.

  And when you eat after cooking with the electromagnetic induction heating cooking device, if you put the inner pot 2 in the outer pot 1 and put it on the table, the food 3 will be hard to cool, and when you want to prioritize the breadth of the table Take 2 out of the pan 1 and place it on the table.

  The cooked food 3 left after the meal can be stored in the refrigerator 2 while being put in the inner pot 2, and can be reheated in the microwave while still in the inner pot 2 before eating.

  Or when reheating with an IH cooking heater, the inner pot 2 can be put into the outer pot 1 (with the heat conductive liquid 4) and reheated (refer FIG. 2).

  FIG. 2: shows another external view of the double pan in the 1st Embodiment of this invention, and the double pan of the electromagnetic induction heating cooking appliance which heat-cooks it.

  In FIG. 2, when using the inner pot 2 as a storage container as it is, the food 3 is prevented from drying with the inner pot lid 6 for storage (FIG. 2). This is prepared separately from the outer pan lid and inner pan lid (not shown) used when cooking with an IH cooking heater, and is made of a non-metallic, hermetically sealed lid that is used for reheating in a microwave oven. May be configured to open air holes.

  As described above, the outer pot 1 and the inner pot 2 are different in size and different from each other by increasing the heat conduction from the outer pot 1 to the inner pot 2 by the heat conductive liquid 4 and the liquid receiver 5. Since a shape may be sufficient, many types of inner pots 2 can be used with one outer pot 1.

  FIG. 3 shows an external view of a double pan in the first embodiment of the present invention and another double pan of an electromagnetic induction heating cooking device that heats and cooks it.

  In FIG. 3, the inner pot 2 is a rectangular parallelepiped. Conventionally, when a pan having a circular cross section is stored in a refrigerator-freezer, a wasteful space is generated in the refrigerator-freezer due to the circular shape.

  Then, in order to improve the space use efficiency of a refrigerator-freezer and a microwave oven, the cross section of the inner pot 2 is made into a rectangle (polygon).

  On the other hand, the cross-section of the outer pan 1 is preferably circular in consideration of the heating coil shape (circular shape) of the IH cooking heater and the cooking action (stirring the food).

  In this way, by making it a double pan, the shape of the outer pan that is easy to heat cook with the IH cooking heater, the shape of the inner pan that can be stored and organized in the freezer refrigerator, and can effectively use the interior of the microwave oven Can be realized.

FIG. 4: shows the external view of the double pan in the 1st Embodiment of this invention, and another double pan of the electromagnetic induction heating cooking appliance which heat-cooks it.

  In FIG. 4, the inner pot 2 is divided into a plurality of parts (inner pots 2a, 2b, 2c, 2d).

  Thereby, when cooking with an IH cooking heater, for example, use four of the inner pots 2a to 2d, and when storing according to the amount of food left after meal, only the inner pot 2a, etc. The number of pots can be adjusted.

  Then, when only the inner pot 2a is stored in the freezer, reheated with a microwave oven, and reheated with an IH cooking heater, the inner pot 2 is put into the outer pot 1 (with heat conductive liquid 4) and reheated. can do.

  Conventionally, there is a problem that the size of the pan cannot be changed even if it is stored in a refrigerator with a cooked pan and reheated in a microwave oven, although the amount of food left after meal is small. Sometimes transferred to a small storage container.

  The double pan of this embodiment adjusts the size at the time of cooking, the size at the time of storage, and the size at the time of reheating without moving the vessel by the number of inner pots, and reduces the space required for storage be able to.

(Embodiment 2)
FIG. 5: shows the external appearance of the double pan in the 2nd Embodiment of this invention, the double pan of the electromagnetic induction heating cooking appliance which heats it, and an electromagnetic induction heating cooking appliance.

  In FIG. 5, the outer pot 1, the inner pot 2, the food 3, the heat conductive liquid 4, and the liquid receiver 5 are the same as those in FIG. 1. This is placed on the electromagnetic induction heating cooking device 7 for cooking.

  The electromagnetic induction heating cooking device 7 includes an outer pan temperature detecting means 8 (for example, a contact temperature sensor or an indirect temperature sensor using infrared rays), and the detected temperature is input to the heating control means 9 to optimally control the heating means 10. I do.

  In addition, since the temperature of the inner pot 2 or the food 3 is important when the double pan is cooked with electromagnetic induction heating cooking equipment as in the present embodiment, the inner pot temperature detecting means 11 is provided.

  For example, as shown in FIG. 5, the inner pot temperature detecting means 11 is provided and fixed to the inner pot lid 12 for cooking, and the temperature of the food 3 is detected.

  The detected inner pot temperature is input to the heating control means 9 via the communication line 13, and the heating control means 9 performs heating cooking control corresponding to the double pot from the detected temperature of the outer pot and the detected temperature of the inner pot. .

  About the double pan comprised as mentioned above and the electromagnetic induction heating cooking appliance which cooks it, the operation | movement and an effect | action are demonstrated below.

  FIG. 6 shows a temperature change graph during cooking of the double pan in the second embodiment of the present invention and the electromagnetic induction heating cooking appliance that cooks it.

  In FIG. 6, the horizontal axis is the cooking time, the vertical axis is the detected temperature, and is detected by the outer pot temperature detecting means 8 (a) the detected temperature of the outer pot and the inner pot temperature detecting means 11 (b). Indicates the detected temperature of the inner pot.

  The temperature at which switching from strong fire heating to medium fire heating is shown in the figure as the high fire heating switching temperature.

  When the heating control means 9 (a) judges the high fire heating switching temperature only by the detected temperature of the outer pan, the heating control means 9 switches from the strong fire to the medium fire at the time timing of (b) in FIG. At this time, the detected temperature of the inner pot (b) is not yet sufficient.

  (B) By inputting the detected temperature of the inner pot into the control means, it is possible to switch from strong fire to medium fire at the time timing of (a) in FIG.

  In this way, considering the structure of the double pan that is not often used in conventional electromagnetic induction cooking equipment, cooking control corresponding to the double pan from the detected temperature of the inner pan in addition to the detected temperature of the outer pan I do.

  That is, (a) If heating control is performed only by the detected temperature of the outer pot, switching to high heat, medium heat, and stewed heating is performed when the inner pot temperature is not yet sufficient.

  When (b) the temperature detected in the inner pot is added to this, it is possible to switch to high heat, medium heat, and stew heating when the heat is passed to the inner pot, and it can be simmered firmly.

  Moreover, the heating control means 9 performs the cooking control corresponding to a double pan, when the correlation of (a) both the detected temperature of an outer pot and (b) the detected temperature of an inner pot satisfy | fills predetermined conditions.

  For example, the change amount of the detected temperature of the outer pot and the detected temperature of the inner pot is determined every predetermined time, and the correlation condition is that both temperature changes are the same.

  When only the detected temperature of the outer pan rises, it is determined that the double pan or the inner pan temperature detecting means 11 is not functioning well.

  Moreover, the temperature difference of the detected temperature of an outer pot and the detected temperature of an inner pot is judged for every predetermined time, and it is set as correlation conditions that both temperature differences are small.

  If the temperature difference is too large, it is determined that the double pan or inner pan temperature detecting means 11 is not functioning well.

  As described above, when it is confirmed that the correlation between the detected temperature of the outer pot and the detected temperature of the inner pot satisfies the predetermined condition, and abnormality is detected, the cooking control corresponding to the above-mentioned double pot is stopped and the outer pot is Heat cooking control is performed only by the temperature detected by the pan.

  Alternatively, all cooking control is stopped and the cook is notified of the abnormality.

  As described above, in the present embodiment, cooking corresponding to the double pan can be performed from the detected temperature of the outer pot and the detected temperature of the inner pot, and the food in the inner pot can be simmered firmly. . Also, if there is an abnormality in cooking, this can be determined and notified / stopped.

  The inner pot temperature detecting means is not limited to the method shown in FIG. 5, but may be an indirect temperature sensor such as infrared rays.

  In addition, there is a method in which the inner pot temperature detection means 11 is not installed on the inner pot lid, but directly attached to the inner pot, or the inner pan temperature detecting means 11 is measured from an upper ventilation fan (not shown) without using the inner pot lid.

  The communication line 13 may be wireless.

  As mentioned above, the double pan concerning this invention and the electromagnetic induction heating cooking appliance which heat-cooks it are applicable not only to a pan but to the use to cooking utensils, such as a device used for cooking.
