Description

  The present invention relates to a pottery cooker for an IH cooking heater to which technical means for smokeless and bromide is added.

  Along with the increasing awareness of environmental issues, in recent years, an IH cooking system equipped with a so-called IH cooking heater in which Joule heat is generated directly on the bottom surface of the heating vessel main body by electromagnetic induction by an induction coil has been rapidly spread. .

  The IH cooking heater not only contributes to environmental problems due to its high thermal efficiency, but is also effective as a fire prevention measure by not generating a flame. However, due to the high system price including the need for a dedicated 200 volt indoor wiring and the heating mechanism that generates heat on the bottom surface of the heating vessel body without using radiant heat, There is a problem that the pottery cooking is not good. In order to cope with this problem, many IH cooking systems include a grilled fish grill incorporating a radiant heater as a heat source in addition to the IH cooking heater.

The need for a dedicated indoor line and price issues in the IH cooking system will gradually improve due to considerations such as making it an indispensable facility at the house design stage, as the degree of spread increases. The fact that the IH cooking system requires two heat sources with different heat generation principles has resulted in greatly reducing the advantages of the IH cooking heater.

As a specific example of the demerit, the IH cooking heater has the advantage of good thermal efficiency. However, in the home where the cooking frequency is high, the result is that the radiant heater is used frequently, and the thermal efficiency of the entire IH cooking system. Can be pointed out. In addition, the IH cooking heater itself enables a slim and modern design with a reduced height dimension. However, the IH cooking heater itself requires a grilled fish and cannot reduce the height dimension. The cooking system as a whole is forced to have a so-called “clean” design that is not much different from the traditional gas range.

The manufacturer is eager to eliminate the grilled fish from the IH cooking system from the viewpoint of reducing the price and eliminating the design limit, but simply by eliminating the grilled fish, Needless to say, it cannot meet the demands of consumers.

The above problem is a problem that can be easily solved if an appropriate pottery cooker is provided that can be used on an IH cooking heater without the need for other energy sources. As a proposal paying attention to this, there is an example of the following high-frequency induction heating cooker (see Patent Document 1 below).

Japanese Patent No. 2990979

  The outline | summary of the high frequency induction heating cooking appliance of the said patent document 1 is as follows. The purpose of this cooking utensil is to realize upper and lower double-sided heating that could not be achieved with conventional IH cooking utensils.

In order to achieve the above object, the cooking appliance has a receiving coil that receives electromagnetic induction of an induction heating coil of an IH cooking heater, and a heating unit that is driven by electric power generated in the receiving coil, in addition to a cooking container that stores cooking ingredients. It is equipped with a special lid. The heating unit installed on the lid is positioned so as to cover the entire top surface of the cooking container when the cooking container is covered. That is, the cooking container is heated from below by induction heating of the cooking container by the IH cooking heater, and the cooking material is heated from above by the heating unit installed on the lid.

  The most characteristic point in the cooking utensil is the power feeding method for the heating unit installed on the lid. Here, the heating part of the lid is a radiant heater that cooks cooking materials by radiant heat instead of induction heating, so it can be driven even using a normal household 100 volt power source, In the cooking utensil, an induction heating coil for an IH cooking heater or a power receiving coil in a lid that receives electromagnetic induction of a power feeding coil arranged in parallel with the coil is used as a power source. As a result, the power supply wiring for the lid can be omitted, which greatly contributes to the improvement of practicality.

Although the cooking utensil described in Patent Document 1 shows a technical viewpoint excellent in a power feeding method for a heating unit installed in a lid, it entails a major problem based on the characteristics of pottery cooking.

For example, the basic differences between grilled food and boiled food are the amount of moisture in the cooked material and the presence or absence of a dark taste. In other words, grilled food cooking can achieve a savory and peculiar flavor different from boiled food by skipping the moisture contained in the cooking material and imparting a dark taste. Therefore, when cooking grilled food, there is a problem of how to treat moisture, oily smoke and odor generated from the cooking material.

  The cooking utensil according to the above proposal has no interest in this problem, and it seems that cooking is performed while the cooking container is shielded by the lid. This can be learned from the fact that if the lid is removed, the heating unit installed in the lid cannot be used. However, when cooking is performed with oil smoke generated from the cooking material confined in the lid, oil smoke dirt adheres to the inner surface of the lid, and smoke carbon adheres to the heating part. It is clear from experience that the material itself will turn blackish due to wrinkles, and it is unclear how to deal with this problem.

  The present invention has a basic problem of solving the problems of oil smoke and odor peculiar to grilled cooking without using an energy source other than the energy generated from the induction coil of the IH cooking heater. The object is to achieve this problem while realizing double-sided baking for cooking ingredients.

  In order to achieve the above object, the present invention employs the following configuration.

(Solution 1)
A pottery cooker for an IH cooking heater according to the present invention covers a heating container body that generates heat by electromagnetic induction by an induction coil that is driven by energizing high-frequency alternating current, and covers the heating container body in the form of a cover lid or a drop lid during cooking. In a pottery cooker for an IH cooking heater composed of a lid, an exhaust port is formed in the lid, and a post-combustion catalyst member is installed in such a posture that the exhaust port is blocked to allow ventilation. In addition, a power receiving coil that generates an electromotive force due to mutual induction between the induction coil and either the heating container body or the lid is attached to the heating container main body and the lid, and the electric power generated by the power receiving coil is Power is supplied to the heater.

  The solution means 1 shows a discharge path of oily smoke and odorous substances generated from cooking materials and a configuration of processing to be received until the oily smoke and the like are discharged.

  In the above-mentioned pottery cooker, cooking is performed with the lid attached to the heating container body. It is a lid for that purpose. The cooking material is cooked by induction heating the inside of the heating container body by an IH cooking heater. The lid is provided with an exhaust port and communicates with the outside air at this portion. The oily smoke generated from the cooking material flows toward the exhaust port so as to be expelled by the steam generated from the cooking material at the same time.

  A post-combustion catalyst member is installed at the exhaust port so as to close the exhaust port so as to allow ventilation. Therefore, the total amount of oil smoke and the like flowing from the exhaust port to the outside air inevitably passes through the post-combustion catalyst member.

  A heater is attached to the post-combustion catalyst member, and this heater is attached to the heating vessel main body or the lid body, and uses a receiving coil that generates an electromotive force by a mutual induction action with the induction coil of the IH cooking heater as a power source. Driven. The heater bears the role of increasing the activity of the post-combustion catalyst member and maintaining the activity. As a result, the oily smoke generated in the heating container body is completely burned by the post-combustion catalyst member when it passes through the exhaust port without using a power source other than the induction coil of the IH cooking heater, and is smokeless and non-brominated.

(Solution 2)
The grilled cooking utensil for the IH cooking heater according to the present invention is based on the invention described in the solution 1 and the exhaust port of the lid is formed at a substantially central position of the lid, and the post-combustion catalyst member can vent the exhaust port. The heater is arranged in a posture facing the bottom surface of the heating container main body at a lower position of the post-combustion catalyst member.

  The solving means 2 shows a configuration for enabling cooking ingredients to be heated from both the upper and lower surfaces. At this time, it is the role of the IH cooking heater that heats the cooking material from the back surface, and it is the role of the heater that heats the cooking material from the top surface. For this reason, a heater is arrange | positioned in the attitude | position which faces the bottom face of a heating container main body in the lower position of a post-combustion catalyst member, and both the function which maintains the activity of a post-combustion catalyst member and the function which heats cooking materials It also serves as.

(Solution 3)
The grilled cooking utensil for the IH cooking heater of the present invention is based on the invention described in Solution 2 and is a heat in which a through hole is formed in a portion corresponding to the post-combustion catalyst member between the post-combustion catalyst member and the heater. It is characterized by interposing a reflector.

  In the solution 3, the heater itself can exhibit a natural heat function for the cooking material and an activity maintaining function for the post-combustion catalyst member while suppressing the temperature of the lid itself from rising to a dangerous temperature. The structure for making is shown.

  The heat reflection plate interposed between the post-combustion catalyst member and the heater, that is, the upper position of the heater can reflect the heat toward the surface side of the lid body and direct it toward the bottom surface of the heating container body. As a result, the heater function of the heater is greatly enhanced, and the temperature rise of the lid is suppressed. However, the heater can heat the post-combustion catalyst member through a through hole provided corresponding to the post-combustion catalyst member, and maintain its activity.

(Solution 4)
The cookware for IH cooking heater of the present invention is based on the invention described in any one of Solution 1 to Solution 3, and the lid is a cover lid whose outer peripheral edge hangs down outside the heating container body. The receiving coil is attached to the outer peripheral edge of the lid.

  The solution 4 shows an advantageous location of the power receiving coil that bears the role of the heater as a power source. An induction coil incorporated in a general IH cooking heater has a very high output, and the range in which the flux linkage from the induction coil reaches is wide. Therefore, if the power receiving coil is on the top plate of the IH cooking system, it can exert a temporary electromotive force. However, the power reception efficiency differs depending on the installation location of the power reception coil. The optimum installation location of the power receiving coil is generally a position that is close to the induction coil and overlaps the induction coil vertically. However, since it is necessary to put a heating container main body in this position, it cannot be used. The sub-optimal installation location is around the bottom surface of the heating container body, which is the position closest to the optimum position.

  Therefore, the lid body is a cover lid whose outer peripheral edge hangs down to the outside of the heating container main body, and the power receiving coil is attached to the outer peripheral edge of the lid body, thereby arranging the power receiving coil at a position close to the ideal position. Can do it.

(Solution 5)
The cookware for IH cooking heater according to the present invention is based on the invention described in any one of Solution 1 to Solution 3, and the heating container body is made of a non-magnetic metal with a heating plate attached to the bottom. Further, the lid body is a drop lid having an outer peripheral edge whose outer dimension exceeds the heat generating plate of the heating container body, and a power receiving coil is attached to the outer peripheral edge of the lid body.

  The solution means 5 shows an advantageous configuration in the case where the power receiving coil can be installed on the lid body that is a drop lid depending on the mode of the heating container body to be used.

  As an IH cooking heater, a heating container body in which an iron-based heat generating plate having an appropriate electrical resistance is attached to the bottom surface of a copper or arinium alloy heating container body is widely used. Copper and aluminum-based metals transmit magnetism, but often do not generate sufficient heat with an IH cooking heater. On the other hand, an iron-based metal can generate heat but cut off magnetism. Moreover, it is necessary to install a receiving coil in the location which can receive the magnetism from the induction coil of IH cooking heater. Therefore, even if it is a drop lid, if the outer peripheral edge has a size that exceeds the heat generating plate of the heating vessel body that blocks magnetism, a receiving coil is attached to the outer peripheral edge of the lid to effectively generate electromotive force. It can be demonstrated.

(Solution 6)
A grilled cooking utensil for an IH cooking heater according to the present invention includes a heating container body that generates heat by electromagnetic induction by an induction coil that is driven by energizing high-frequency alternating current, and a cover lid or a drop lid that covers the heating container body during cooking. In a pottery cooker for an IH cooking heater comprising a lid that is covered with, a post-combustion catalyst member is installed in a posture in which an exhaust port is formed in the heating container body and the exhaust port is shut off so as to allow ventilation. A heater for sustaining the activity is attached, and a receiving coil for generating electromotive force is added to the heating vessel main body by mutual induction action with the induction coil, and the electric power generated by the receiving coil is supplied to the heater. And

  The solution means 6 shows a configuration in which an exhaust port for discharging oily smoke generated from cooking materials is provided not in the lid but in the heating container body. The difference from the solution 1 is substantially only the position of the exhaust port. As described above, in grilled food cooking, steam is generated from cooking materials together with oil smoke and the like, and this steam functions to forcibly extrude oil smoke and the like, so it is necessary to limit the position of the exhaust port to the lid. There is no. In addition, when providing an exhaust port in a heating container main body, it is advantageous to provide a receiving coil also in a heating container main body.

(Solution 7)
The grilled cooking utensil for the IH cooking heater of the present invention is based on the invention described in Solution 6, and the heating container body is made of a non-magnetic metal with a heating plate attached to the bottom surface, and the receiving coil has a receiving coil. It is attached to the nonmagnetic metal part of the heat vessel main body.

  The solution means 7 shows an advantageous attachment location when the power receiving coil is attached to the heating container main body. The gist is the same as that described with respect to the solution means 5.

(Solution 8)
The ceramic cooker for IH cooking heater according to the present invention is based on the invention described in any one of Solution 1 to Solution 7, and the ceramic substrate having a honeycomb structure in which the combustion catalyst member can be vented through the cell holes thereafter. It is a breathable post-combustion catalyst member in which an oxidation promoting catalyst agent is supported.

  The solving means 8 shows a specific configuration of the post-combustion catalyst member. The post-combustion catalyst member used in the pottery cooker according to the present invention is required to have a breathable structure because it requires oil smoke or the like to pass therethrough. As a breathable structure, for example, a mesh structure or the like is generally used. However, in the mesh structure or the like, it is difficult to adjust the time and area of action as a catalyst for passing smoke or the like. . Therefore, in the present invention, a post-combustion catalyst member is used in which an oxidation promoting catalyst agent is supported on a ceramic substrate having a honeycomb structure. Since the honeycomb structure can easily adjust the passage time and the working area of oily smoke and the like by adjusting the thickness, the capacity can be optimized every time the mounting position is different.

  The present invention includes a heating container body that generates heat by electromagnetic induction by an induction coil of an IH cooking heater, and a lid body that is provided with an exhaust port that discharges oily smoke generated from cooking materials. A catalyst member and a heater for sustaining catalyst activity are attached, and a receiving coil that generates an electromotive force is added to either the heating vessel main body or the lid by mutual induction between the induction coil of the IH cooking heater. In addition, since the electric power generated by the power receiving coil is supplied to the heater, oil smoke and odor substances generated from the pottery cooking material can be completely burned by the post-combustion catalyst member, so that the pottery cooking can be performed only by the IH cooking heater. A very convenient IH cooking machine that can simultaneously perform post-treatment such as oily smoke generated from cooked food ingredients It is possible to provide a pottery cooking utensils for data. The present invention is of particular significance in the indirect effect that this makes it possible in practice to omit the grilled fish from the IH cooking system.

Further, in the present invention, the heater is disposed between the post-combustion catalyst member and the bottom surface of the heating container main body, and the heater has both the function of sustaining the activity of the post-combustion catalyst member and the function of heating to the cooking material. Without reducing the smoke-free and bromide effect, it is possible to realize upper and lower double-sided baking that has been impossible with conventional cooking utensils for IH cooking heaters.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a pottery cooker for an IH cooking heater of the present invention will be described with reference to the drawings.

(Embodiment 1)
The pottery cooker 60 incorporates a metal heating container body 61 that is compatible with the IH cooking heater 100, that is, a metal heating container body 61 that generates heat by the electromagnetic induction action of the induction coil 10 of the IH cooking heater 100, and a member unique to the present invention. It consists of a lid 62 (FIG. 1).

  The heating container body 61 has the same appearance and production as a general frying pan having a handle 6C attached to the side surface 6A, and contains and uses a cooking material M for grilled dishes.

  On the other hand, the lid body 62 is set to have a slightly larger outer shape than the heating container body 61, and the outer peripheral edge 6 </ b> E of the lid body 62 is outside the heating container body 61 in a state where the lid body 62 is attached to the heating container body 61. It becomes a combination that droops deeply. That is, the lid 62 is a so-called cover lid that covers the entire heating container body 61. The lid body 62 includes an independent handle 6D, and can be used in a mode in which the handle 6C of the heating container main body 61 is passed through a hole 6H provided in a part of the side surface.

  A power receiving coil 1 that generates an electromotive force due to mutual induction with the induction coil 10 of the IH cooking heater 100 is attached to the outer peripheral edge 6E of the lid 62. The power receiving coil 1 is molded with a heat-resistant resin and attached so as to be fitted onto the outer peripheral edge 6E of the lid 62. The meaning that the outer peripheral edge 6E of the lid 62 hangs down is to make the power receiving coil 1 as close as possible to the top plate P of the IH cooking heater 100 and eventually the induction coil 10.

  A central portion of the lid 62 is formed at a middle height, and a large-diameter exhaust port H1 is formed at the middle-high portion. The exhaust port H1 is formed in a shallow circular duct shape, and a disc-type post-combustion catalyst member 3 having substantially the same diameter is fitted therein (FIGS. 1 and 2). The post-combustion catalyst member 3 is formed by supporting an oxidation promoting catalyst on a ceramic substrate having a honeycomb structure in which a large number of cell holes 3H are formed, and has high air permeability. A suitable catalyst used is, for example, platinum palladium.

  The heat reflecting plate 4 is attached to the back side of the lid 62, that is, the inner side surface. The heat reflecting plate 4 is formed in an inverted dish shape, and is attached in a posture along the lid body 62 with a certain distance from the lid body 62. A through hole H <b> 2 corresponding to the diameter of the rear combustion catalyst member 3 is formed immediately below the rear combustion catalyst member 3 of the heat reflecting plate 4.

  The heater 2 is attached to the lid 62 below the heat reflecting plate 4. A sheathed heater that is bent so as to belong to a single plane is used as the heater 2, and the power receiving coil 1 attached to the outer peripheral edge 6 </ b> E of the lid 62 is connected to the heater 2.

  The receiving coil 1 can exert an electromotive force by sharing the magnetic field G generated by the induction coil 10 driven by high-frequency alternating current when the IH cooking heater 100 is used (FIG. 2). In other words, it is the same principle as a transformer. Therefore, the heater 2 is driven using the power receiving coil 1 as a power source without requiring external power supply wiring. Note that the number of windings of the power receiving coil 1 can be obtained experimentally in consideration of the relative positional relationship with the induction coil 10 and the capacity of the heater 2.

  The heater 2 heats the cooking material M by natural heat, performs primary combustion of oily smoke and odorous substances generated from the cooking material M, and further heat-activates the post-combustion catalyst member 3 through the through holes H2 of the heat reflecting plate 4. The oily smoke discharged so as to be pushed out from the exhaust port H1 by the steam generated from the cooking material M can be secondarily burned and smokeless and brominated. The heat reflecting plate 4 increases the efficiency of the heater 2 and prevents the lid 62 from rising to a dangerous temperature.

(Embodiment 2)
For the heating container main body 61 in the pottery cooker 60 of the present invention, a copper or aluminum product in which a heating plate 6F that reacts with the IH cooking heater 100 is bonded to the bottom surface 6B can be used (FIG. 3). The illustrated heating container body 61 has a two-handed pan design with a pair of handles 6C, 6C.

  Further, the lid body 62 is a drop lid type that enters the inside of the heating container main body 61, and the power receiving coil 1 can be attached to the front side or the back side of the outer peripheral edge 6 </ b> E of the lid body 62. In addition, in the case of this form, it is preferable to set it as a dimension larger than the cover body 6F. This is because the portions other than the heating plate 6F do not block magnetism, so that the power receiving coil 1 can function effectively.

  The heater 2 can be a small size dedicated to heating the post-combustion catalyst member 3. In this case, the heat reflection 4 is unnecessary. Thereby, the whole structure of the pottery cooker 60 can be simplified, without reducing the processing function, such as oil smoke, by the post-combustion catalyst member 3.

(Embodiment 3)
Although the heater 2 for the post-combustion catalyst member 3 is attached to the lid body 62, the power receiving coil 1 is not necessarily attached to the lid body 62 side. Specifically, for example, it can be arranged around a heating plate 6F bonded to the bottom surface 6B of the heating container body 61 (FIG. 4).

  Since the periphery of the heating plate 6F is close to the induction coil 10 of the IH cooking heater 100, and the hourly speed from the induction coil 10 is not blocked by the heating plate 6F, the power receiving coil 1 installed in this portion functions extremely efficiently. can do. However, in this embodiment, it is necessary to make an electrical connection from the heating container main body 61 side to the lid body 62 side. Therefore, a connector 5 that can be turned on and off by attaching and detaching the lid 62 is attached between the two.

(Embodiment 4)
The exhaust port H1 in the pottery cooker 60 can be provided in the heating container main body 61 (FIG. 5). In this case, since the exhaust port H1 is unnecessary for the lid 62, a general lid 62 having a handle 6D at the center position can be used.

  A short duct 6P is attached to the side surface 6A of the heating container main body 61, and an opening of the duct 6P becomes an exhaust port H1. A rear combustion catalyst member 3 and a dedicated hite 2 are built in the duct 6P. Power is supplied to the heater 2 from the power receiving coil 1 disposed on the bottom surface 6B of the heating container main body 61.

  When the lid 62 is not used, the oil smoke generated from the cooking material M diffuses above the heating container body 61. However, as long as cooking is performed using the lid 62, the generated oil smoke, etc. The steam is forcibly discharged from the exhaust port H1 by the vapor pressure generated from the cooking material M. Therefore, the post-combustion catalyst member 3 is inevitably passed. In this embodiment, the exhaust ports H1 can be provided at two or more places on the heating container main body 61 as necessary.
