Description

  The present invention relates to an induction heating heating element in which an eddy current is induced by a high-frequency magnetic field generated by an electromagnetic induction heating coil included in an electromagnetic cooker and the like, and heats an object to be heated by generating Joule heat, and such induction heating. The present invention relates to an induction heating container provided with a heating element.

  In recent years, instead of cooking appliances that have been mainly gas appliances, cooking appliances generally called electromagnetic cookers are used in the food and beverage industry in terms of safety, cleanliness, convenience, and economy. Not only for use, but also for general households.

  However, this type of electromagnetic cooker uses a flame because it generates a high-frequency magnetic field by an electromagnetic induction heating coil provided inside and heats the object to be heated by Joule heat generated by the induced eddy current. However, there is a disadvantage that a cooking utensil made of a magnetic metal such as iron or iron enamel must be used.

For this reason, various containers made of non-magnetic materials that can be used in an electromagnetic cooker have been proposed to eliminate the disadvantages of the electromagnetic cooker described above.
For example, Patent Document 1 discloses a plastic container for an electromagnetic cooker in which a conductor is embedded in the bottom. Patent Document 2 discloses an instant food container made of a heat insulating material having a heating element made of a steel plate on the inner surface of the bottom surface. Patent Document 3 discloses a bottomed cylindrical container made of a non-conductive material. An induction heating cooking container having a main body and a heating element that generates heat by electromagnetic induction is disclosed.
Patent Document 4 discloses an induction heating tool used in combination with a container body made of a nonmagnetic material.

However, the container of patent document 1 forms a container in the state embedded completely, without exposing a conductor to the surface.
Therefore, in the configuration disclosed in Patent Document 1, since all of the heat generated by the conductor reaches the container and this may damage the container, the plastic raw material forming the container is described in Patent Document 1. As described above, it is not only limited to a heat resistant resin such as unsaturated polyester or melamine resin, but it also has a problem that it is difficult to separate the conductors embedded during the disposal process.

  Patent Document 2 intends to provide an instant food container that can be heated as it is, and exemplifies foamed polystyrene, paper, etc. as the material of the container, and removes the heating element from the container. Although there is a statement that it can be made possible, no consideration is given to the damage of the container due to the heat generated in the heating element.

  On the other hand, in Patent Document 3, a concave portion is formed in the heating element, and a space is provided between the heating element and the bottom of the container main body, thereby reducing the contact area between the heating element and the container main body, and the space portion. There is a description that the effect of heat on the container body can be suppressed by the heat insulation effect of the water and the water that has entered the space.

However, with the configuration disclosed in Patent Document 3, the contact between the heating element and the container body cannot be eliminated at all. For this reason, the container of patent document 3 still has a possibility that a container main body may be damaged in a contact part with a heat generating body, and if a heating target object contains a lot of water, it will circulate water. Although the heat dissipation effect can be expected, especially when the water contained in the heating object is lost during the heating process, such as when it is used for cooking rice, avoid damaging the container body at the contact point with the heating element. In addition, there is a possibility that the object to be heated is burnt.
Therefore, after all, the container disclosed in Patent Document 3 has a problem that only a container containing a large amount of water can be heated and its application is limited.

In Patent Document 4, the permeability of the magnetic shunt alloy material is controlled to appropriately set the characteristic temperature of the heating element, thereby suppressing the amount of heat generated by the heating element and avoiding damage to the container. .
However, since the induction heating tool of Patent Document 4 uses a magnetic shunt alloy material, the selection of the material is restricted, and in addition, it takes troublesome to prepare such a magnetic shunt alloy material. In particular, when used in combination with an instant food container, there is a problem that the cost cannot be balanced and the cost disadvantage cannot be ignored when it is disposable together with the container.

  The present invention has been made in view of the above circumstances, and when a heating object is heated by an electromagnetic cooker or the like, the container to be used is prevented from being damaged or the heating object is burnt with a very simple configuration. An object of the present invention is to provide an induction heating heating element that can be manufactured at low cost and has excellent versatility, and an induction heating container including such an induction heating heating element.

  An induction heating heating element according to the present invention that solves the above-described problems is formed by encapsulating a conductive member that generates heat when an eddy current is induced by a high-frequency magnetic field, together with a heat conductive medium that covers the periphery of the conductive member. As a configuration.

  With such a configuration, the conductive member is generated because the conductive member that generates heat by the eddy current induced by the high-frequency magnetic field is not in direct contact with the container to be used for heating the heated target or the heated target. It is possible to prevent the container from being damaged by heat or scorching the object to be heated.

The induction heating heating element according to the present invention may be configured such that the heat conducting medium is a liquid material.
With such a configuration, it is possible to prevent the heat conductive medium from convection inside the enclosing member and uniformly cool the conductive member, and the temperature of the conductive member to be locally increased.

Moreover, the induction heating heat generating body which concerns on this invention can be set as the structure in which the said enclosure member has a degassing part.
With such a configuration, it is possible to prevent the heating element from being damaged due to an increase in internal pressure.

In addition, in the induction heating heating element according to the present invention, the conductive member can be used without particular limitation as long as it generates heat by inducing an eddy current by a high-frequency magnetic field. For example, the conductive member may be made of a metal plate or a metal foil.
Such a conductive member is preferably provided with a large number of pores to promote convection of the heat transfer medium in the enclosing member so that the conductive member is cooled more uniformly. In order to improve the cooling effect of the conductive member by convection of the heat conductive medium, the conductive member may be configured by providing a conductive coating layer on a base material made of woven fabric or non-woven fabric.

In addition, the induction heating heating element according to the present invention may have a configuration in which one or more convection holes are provided at an arbitrary position.
With such a configuration, the object to be heated is likely to convect between the back side and the surface side of the heating element, causing problems such as damaging the container and scorching the object to be heated. It can prevent more effectively.

In addition, the induction heating heating element according to the present invention may be configured such that the enclosing member is reinforced in correspondence with a position where the eddy current density of the conductive member increases.
With such a configuration, even if there is a portion where the temperature locally increases in the conductive member, it is possible to prevent damage to the heating element and local increase in temperature of the heating element.

Moreover, the induction heating heating element according to the present invention can be configured such that the eddy current density is made uniform by changing the thickness of the conductive member.
With such a configuration, the cross-sectional area of the conductive member orthogonal to the flow direction of the eddy current can be made constant, the eddy current density can be made uniform, and the local temperature rise of the conductive member can be prevented.

Moreover, the induction heating heat generating body which concerns on this invention can provide a fuse function by notching the arbitrary positions of the said electrically-conductive member, or making the arbitrary positions of the said electrically-conductive member thin.
With such a configuration, it is possible to prevent the heating element from generating heat to a certain temperature or more with a very simple configuration.

Moreover, the induction heating container according to the present invention is configured to include the induction heating heating element as described above.
By adopting such a configuration, the induction heating heating element can heat an object to be heated without damaging the container. Therefore, the material forming the container body is required to have characteristics such as heat resistance. The low-cost container which can be used with an electromagnetic cooker can be easily provided by forming the container body from any nonmagnetic material.

  According to the present invention, since the conductive member that generates heat by the high-frequency magnetic field does not directly touch the container used when heating the heating target or the heating target, the container is damaged by the heat generated by the conductive member. It is possible to prevent the heating object from being burned or to be burned, and the conductive member can be arbitrarily selected as long as it generates heat by a high-frequency magnetic field. Since it is not necessary to prepare using, it is advantageous in terms of cost.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[First embodiment]
First, a first embodiment of the induction heating heating element according to the present invention will be described.
Here, FIG. 1A is a top view schematically showing the induction heating heating element according to the present embodiment, and FIG. 1B is a cross-sectional view taken along line AA of FIG. FIG. 7 is a schematic view showing an example of use of the induction heating heating element according to the present embodiment.

  The heating element 1 shown in FIG. 1 has a conductive member 2 that is eddy current induced by a high-frequency magnetic field generated from an electromagnetic induction heating coil included in an electromagnetic cooker 10 and the like, and the conductive member 2 that generates heat by its Joule heat has substantially the same shape as the conductive member 2. The encapsulating member 3 is encapsulated together with the heat conducting medium 4. And as for such a heat generating body 1, when the heating object M is heated with the electromagnetic cooker 10, for example, as shown in FIG. 7, the container 11 used at this time consists of a nonmagnetic material. Also, the heating object M can be arranged and used at the bottom of the container 11 so that the heating object M can be heated.

  When the heating element 1 of the present embodiment is used for heating cooking using such an electromagnetic cooker 10, the conductive member 2 that generates heat by a high-frequency magnetic field can directly touch the container 11 or the heating object M. Instead, the heat generated by the conductive member 2 heats the heating object M via the heat conductive medium 4. For this reason, the trouble that the container 11 is damaged by the heat which the electrically-conductive member 2 emits, or the heating target M is burned can be avoided effectively.

  At this time, particularly when the heating object M is in a liquid state, in order to prevent the heating object M from staying on the back side of the heating element 1, that is, between the heating element 1 and the container 11, the heating element. A convection hole 5 that penetrates the heating element 1 is provided at an arbitrary position 1 (substantially in the center in the illustrated example), and the heating object M is easily convected between the back surface side and the front surface side of the heating element 1. It is preferable to do so, and this makes it possible to avoid the above problems more effectively.

  In the present embodiment, the heat conducting medium 4 may be any material that can transmit heat to the heating object M that is in contact with the heating element 1 while heating the heat generated in the conductive member 2. Although there is no restriction | limiting in particular in the heat conductive medium 4 which can be used by this embodiment, From a viewpoint of avoiding the local temperature rise of the electrically-conductive member 2, it is possible from the circumference | surroundings of the electrically-conductive member 2 by the convection in the enclosure member 3. The liquid is preferably a liquid having a low viscosity so that heat can be removed (cooled) as uniformly as possible.

  More specifically, water, oils, etc. can be used as the heat conduction medium 4, and as oils, considering the case where the encapsulating member 3 is damaged and leaks, soybean oil, rapeseed oil, Use edible oils such as olive oil, rice oil, corn oil, ben flower oil, sesame oil, palm oil, castor oil, avocado oil, coconut oil, almond oil, walnut oil, and squeeze oil. Is preferred.

  Here, the concept of the “liquid material” includes a material that is solid at room temperature and melts due to heat generated by the conductive member 2 and exhibits fluidity when the heating element 1 is used. Shall. Therefore, as the liquid material used for the heat conductive medium 4, one or a mixture of two or more edible animal and vegetable oils and fats that are liquid at the time of use due to heat generation of the conductive member 2 may be used. It can also be used by mixing with the edible oil described above.

  Further, when such a liquid material is used as the heat conducting medium 4, the conductive member 2 enclosed with the heat conducting medium 4 is in a state of being lifted in the heat conducting medium 4 by the magnetic field generated by the eddy current, and the heat conducting medium 4 Since the medium 4 flows and wraps around the lower side of the conductive member 2 to increase the amount of the heat conductive medium 4 on the lower side of the conductive member 2, damage to the container 11 can be avoided more effectively. .

  Further, in the example shown in FIG. 1, the encapsulating member 3 includes two film materials composed of a front surface material 3 a and a back surface material 3 b having substantially the same shape as the conductive member 2, along the outer shape of the conductive member 2. The conductive member 2 and the heat conducting medium 4 are sealed by heat sealing, but the specific form of the sealing member 3 is not particularly limited. For example, as shown in FIG. 1 (c), the enclosing member 3 may have a side surface portion sealed with an auxiliary member 3c. Although not particularly illustrated, the enclosing member 3 has a rectangular flat bag shape. It is good also as a thing, and the heat generating body 1 can also be made to form by making a bag in the state which enclosed the electrically-conductive member 2 and the heat conductive medium 4. FIG.

  In forming the heating element 1, for example, an unsealed portion is left in a part of the enclosing member 3 with the conductive member 2 previously inserted, and the heat conduction medium 4 is injected from the unsealed portion. The encapsulating member 3 may be sealed by heat-sealing the unsealed portion later.

In the present embodiment, the material used for the enclosing member 3 is not particularly limited as long as it can seal and enclose the conductive member 2 and the heat conducting medium 4. For example, it is possible to use a single layer or a laminate of two or more film materials composed of polyolefin resins such as polypropylene and polyethylene; polyamide resins such as nylon; polyester resins such as polyethylene terephthalate.
When forming the encapsulating member 3 using such a material, the enclosing member 3 may be transparent in whole or in part so that the internal state can be visually confirmed, or given any printing or coloring. It may be possible to provide designability or to describe precautions for use.

In addition, the conductive member 2 in the present embodiment may be any member as long as eddy current is induced by a high-frequency magnetic field and Joule heat is generated by its electric resistance. For example, various metal materials in a plate shape or a foil shape are used. Can do. In the present embodiment, examples of the metal that can be used as the conductive member 2 include aluminum, nickel, gold, silver, copper, platinum, iron, cobalt, tin, and zinc, and alloys thereof.
Although the specific shape of such a conductive member 2 is not particularly limited, it is preferable that the conductive member 2 has a disk shape as illustrated in consideration of the flow of eddy current induced by a high-frequency magnetic field.

Further, in the case where a liquid material is used as the heat conducting medium 4 in the conductive member 2, a large number of the conductive members 2 as shown in FIG. 2 can be promoted so that convection of the heat conducting medium 4 in the enclosing member 3 can be promoted. It is preferable to drill the internal convection hole 2a. Thereby, heat can be taken more uniformly from the periphery of the conductive member 2 and a local temperature rise of the conductive member 2 can be suppressed.
2 is an enlarged cross-sectional view of a portion surrounded by a chain line B in FIG.

  In order to facilitate the convection of the heat transfer medium 4 in the enclosing member 3, the conductive member 2 is a base material made of woven fabric or non-woven fabric, instead of having the above-described configuration. The conductive coating made of the above metal is applied to the surface of the fiber forming the base material by an appropriate means such as electroless plating or coating while leaving a large number of holes communicating with the front side and the back side. It can also be set as the structure which provided the layer.

Furthermore, as shown in FIG. 3A, the conductive member 2 can be provided with a fuse function by forming a notch 2b at an arbitrary position as shown in FIG.
That is, when a part of the conductive member 2 is cut out, the sum of the cross-sectional areas along the radial direction becomes smaller than the other parts by the cut-out part, and the density of eddy currents flowing through the cross-section of this part increases and heat is generated. Since a portion having a relatively large amount is generated, when the conductive member 2 generates heat to a temperature higher than a certain level, the portion where the heat generation amount is intentionally increased is damaged first, for example, FIG. A crack 2c as shown in FIG. 3 (b) is generated to prevent the flow of eddy currents and to function as a fuse.

Thus, by forming the notch 2b in the conductive member 2 and appropriately adjusting the shape, the size of the notch, etc., it is possible to prevent the conductive member 2 from being heated above a certain level. Such a fuse function can be realized by thinning an arbitrary position of the conductive member 2 according to the same principle, and can also be realized by a combination of the notch portion 2b and the thin portion.
At this time, the thinned portion is preferably formed along the radial direction of the conductive member 2, whereby the direction in which the crack 2 c that prevents the flow of eddy current is generated can be controlled.

[Second Embodiment]
Next, a second embodiment of the induction heating heating element according to the present invention will be described.
Here, FIG. 4A is a top view illustrating an outline of the induction heating heating element according to the present embodiment, and FIG. 4B is a cross-sectional view taken along the line C-C in FIG.

This embodiment is different from the first embodiment described above in that a degassing part is formed in the enclosing member 3.
That is, when a liquid material is used for the heat conduction medium 4, especially when water is used for the heat conduction medium 4, the heating temperature of the heating object M is usually near the boiling point of water, so There is a possibility that the heat generating body 1 (encapsulation member 3) breaks due to the boiling of water, which is the conductive medium 4, and the internal pressure increases, but in this embodiment, the encapsulating member 3 is formed. In addition, the steam is allowed to escape from the degassing portion so that the increase in the internal pressure of the heating element 1 can be suppressed.

  For example, as shown in FIG. 4, such a gas venting part has one or two or more gas venting holes 6 formed at an arbitrary position of the enclosing member 3 and allows passage of gas (vapor). However, it can be formed by closing the gas vent hole 6 with a sheet material 6 a having a large number of communication holes of a size that does not allow liquid (water) to pass therethrough.

  This embodiment is different from the first embodiment described above in the above points, and the other configurations are the same as those in the first embodiment, and thus detailed description of other configurations is omitted.

[Third embodiment]
Next, a third embodiment of the induction heating heating element according to the present invention will be described.
Here, Fig.5 (a) is a top view which shows the outline of the induction heating heating element which concerns on this embodiment, FIG.5 (b) is DD sectional drawing of Fig.5 (a). FIG. 6A is a top view schematically showing a modification of the present embodiment, and FIG. 6B is a cross-sectional view of the conductive member 2 corresponding to the EE cross section of FIG. 6A. It is.

  In the first embodiment described above, in the example shown in FIG. 1, one convection hole 5 is provided at substantially the center of the heating element 1, but in the example shown in FIG. 5 as this embodiment, the heating element. 1 is provided at approximately the center of the convection hole 5a, and four convection holes 5b are provided at substantially equal intervals around the convection hole 5a. Convection of the heating object M is more easily generated.

In the present embodiment, the number of convection holes 5 (5a, 5b) and the positions of the convection holes 5 are not limited to the illustrated example, but the convection holes 5 (5b) ), As in the case of forming the notch portion 2b in the first embodiment, the sum of the cross-sectional areas along the radial direction in the portion where the convection hole 5b is provided is smaller than that in the other portions. The density of eddy current flowing through the cross section is increased, and the amount of heat generation is relatively increased.
It is possible to provide the conductive member 2 with a fuse function by providing the convection hole 5b instead of forming the notch 2b or the like, but when the notch 2b for providing the fuse function is separately formed, etc. Therefore, it is necessary to cope with a partial increase in the amount of heat generated by providing the convection hole 5b.

In the present embodiment, the heating element 1 is prevented from being damaged due to a partial increase in the amount of heat generated by providing such a convection hole 5b.
That is, as shown in the figure, when the convection hole 5b is provided concentrically with respect to the center of the conductive member 2, generally, on the outer diameter side of the conductive member 2 along the radial direction at the portion where the convection hole 5b is provided. Although the amount of heat generation tends to increase at the edge of the convection hole 5b and the outer peripheral edge of the conductive member 2, the present embodiment prevents the heating element 1 from being damaged due to such an increase in the amount of heat generation.

In the present embodiment, the heat insulating portion 7 is formed on the inner surface of the base film 3b on the back surface side of the encapsulating member 3 in the portion where the amount of generated heat tends to increase (the portion surrounded by the middle chain line in FIG. 5A). The enclosure member 3 is prevented from being damaged and the temperature of the heating element 1 is prevented from rising locally.
The heat insulating portion 7 formed on the encapsulating member 3 can be formed, for example, by making the thickness of the film base 3b forming the encapsulating member 3 thicker than other portions. Since it is easy to manufacture, it is preferable to form the same kind or different kinds of film materials or other reinforcing members by sticking them to the corresponding portions.

  Further, the present embodiment can be modified as shown in FIG. In the modification shown in FIG. 6, the portion shown by the oblique line in FIG. 6 (a) is the thick portion 2d in which the thickness of the conductive member 2 is changed, and the cross-sectional area of the conductive member 2 orthogonal to the flow direction of the eddy current is The eddy current density is made uniform by this so that the local temperature rise of the conductive member 2 does not occur.

  This embodiment is different from the first embodiment described above in the above points, and the other configurations are the same as those in the first embodiment, and thus detailed description of other configurations is omitted.

  While the present invention has been described with reference to the preferred embodiment, it is needless to say that the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. .

For example, in the above-described embodiment, the heating element 1 having a circular shape is taken as an example. However, the heating element 1 may have various shapes depending on the shape of the bottom of the container 11 to be used. Can do. Even if the shape of the bottom portion of the container 11 to be used is circular, the heating element 1 is placed in a state in which the heating element 1 is square and the four corners thereof are raised along the side walls of the container 11. It is also possible to use it by arranging it at the bottom.
At this time, the shape of the conductive member 2 may be a square shape, and by heating a part of the conductive member 2 along the side wall of the container 11, the heating object M can be heated from the side wall side of the container 11. It becomes.

  Further, the conductive member 2 may be provided with a heat insulating layer as required, and thereby the influence of heat applied to the enclosing member 3 may be reduced. At this time, the heat insulating layer is preferably provided on the back surface side of the conductive member 2, but may be provided on the front surface side of the conductive member 2 as long as the thermal efficiency when heating the heating target M is not impaired.

  In addition, the induction heating container according to the present invention is configured to include the heating element 1 as described above, and the heating element 1 is usually mounted so as to be disposed at the bottom of the container. Any one or both of the container side may be provided with any attachment means such as a fixing claw that facilitates separation during disposal.

  In such an induction heating container according to the present invention, the container body does not directly contact the conductive member 2 that generates heat by electromagnetic induction, and it is necessary to consider the damage to the container body due to the heat generated by the conductive member 2. Therefore, the material forming the container body does not require characteristics such as heat resistance. Therefore, for example, as a container for conventional instant foods, a low-cost container that can be used in an electromagnetic cooker can be easily formed by forming the container body from a general-purpose non-magnetic material such as expanded polystyrene. Can be provided.

  As described above, the present invention eliminates the disadvantages of an electromagnetic cooker that requires the use of a dedicated cooking utensil, and can not only heat a heating object even using a container made of a non-magnetic material. The present invention provides an induction heating heating element excellent in versatility capable of preventing damage to a container to be used and burning of an object to be heated, and an induction heating container provided with such an induction heating heating element.
