And the induction heating cooking appliance which has arrange | positioned the catalyst heater and the catalyst in the exhaust duct is disclosed in order to purify | clean and deodorize the oil smoke which generate | occur | produces when a fish etc. are baked in a roaster warehouse (for example, refer patent document 1). ).

Japanese Patent Laying-Open No. 2006-29596 (page 6-7, FIG. 4)

However, since the invention disclosed in Patent Document 1 uses a catalyst as the smoke removal means, there is a problem that the manufacturing cost increases.
In other words, the smoke generated is colorless and odorless if it is sufficiently oxidized, but in many cases, it does not become fully oxidized, so white smoke with organic components remaining is generated. . In order to promote this oxidation reaction even at a low temperature, it was activated using a catalyst such as platinum-palladium, but it was expensive due to the rare metal. In the present invention, the process of oxidizing the generated smoke to make it colorless and non-brominated is referred to as “desmoking”.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a heating cooker that enables smoke removal without using an expensive catalyst, and an induction heating cooker having the heating cooker. And

The cooking device according to the present invention includes a roaster box for storing an object to be heated, a heating unit for heating the object to be heated, and smoke generated when the object to be heated is heated by the heating unit. a vent port for discharging from the flue gas passage communicating with the vent opening, provided in the flue gas passage, and a hot de-smoke unit for heating the smoke discharged from the roaster box, before Symbol hot de smoke unit includes a conductive material having gas permeability having electrodes at both ends, is connected to the electrode, having an electric circuit means for heating the conductive material, conductive having a front Symbol fever breathability Smoke discharged from the roaster cabinet is allowed to pass through the body material, and a heat insulating material or a heat insulating structure is provided around the vent .

  Since the present invention is configured as described above, the smoke generated in the roaster cabinet is heated to a high temperature (for example, 600 ° C. or higher) in the high temperature dehumidifying section, and thus is sufficiently oxidized, colorless and odorless. It is discharged from the smoke passage as a gas.

  Hereinafter, the heating cooker according to the first embodiment of the present invention will be described using an induction heating cooker. In addition, since each sectional view schematically represents the constituent members, the shape and size (relative size, aspect ratio) are not limited to the illustrated forms. Moreover, the same code | symbol is attached | subjected to the same part in each figure, or a corresponding part, and one part description is abbreviate | omitted.

[Embodiment 1: High temperature smoke removal unit]
1 and 2 schematically illustrate a heating cooker according to Embodiment 1 of the present invention. FIG. 1 is a cross-sectional side view showing the whole, and FIG. 2 is a partial example. It is sectional drawing of the side view shown. In FIG. 1, the heating cooker 100 includes a box-shaped main body 10 and a box-shaped roaster cabinet 20 that is installed inside the main body 10 and opens to the front surface 11 of the main body 10.
An exhaust port 12a is formed in the top plate (same as the top surface) 12 of the main body 10, a front opening portion 11a is formed in the front surface 11 of the main body 10, and the side surface of the roaster cabinet 20 is airtight in the front opening portion 11a. It is joined. A roaster door 21 is openably and closably installed at the front opening of the roaster cabinet 20, and a vent 23 a is formed on the back surface 23 of the roaster cabinet 20. In addition, the roaster door 21 is formed with an intake port (not shown) through which outside air flows.

A smoke exhaust passage (same as the smoke exhaust duct) 30 that connects the air vent 23a of the roaster cabinet 20 and the exhaust port 12a of the main body 10 is installed, and passes through a position near the air vent 23a of the smoke exhaust passage 30. A high temperature smoke removal unit 40 for heating gas (including smoke) is provided.
Accordingly, the outside air that has passed through the inlet of the roaster door 21 and has flowed into the roaster cabinet 20 passes through the vent 23a and flows into the flue gas passage 30, and is eventually discharged out of the cabinet through the exhaust port 12a. become.
At this time, the smoke generated by heating the fish or the like in the roaster cabinet 20 is heated to a high temperature (for example, 600 ° C. or higher) in the high-temperature smoke removal unit 40 and is sufficiently oxidized, so that the organic components disappear. It becomes colorless and odorless gas (not white smoke) and is discharged from the exhaust port 12a. Therefore, since it is not necessary to use a catalyst made of a rare metal such as platinum-palladium for desmoking, the manufacturing cost is reduced.

In addition, an induction heating coil is disposed on the lower surface of the top plate 12, and a power supply means for operating the induction heating coil, a control means, and an internal cooling fan for cooling these are disposed in the main body 10. ing. A roaster net (iron rail) for placing an object to be cooked (fish or the like) is arranged inside the roaster cabinet 20, a lower electric heater is disposed below the grill net, and an upper electric heater is disposed above. Are arranged so that the fish placed on the grill can be heated from both sides. An exhaust fan may be installed in the smoke passage 30. At this time, the blades constituting the exhaust fan may be disposed in the smoke exhaust passage 30 and the drive motor for driving the blades may be disposed outside the smoke exhaust passage 30 (the same in the main body 10). In addition, since the above structure is the same as the conventional induction heating cooking appliance, neither is shown in figure.
By the way, although the above has demonstrated what the heating cooker 100 equips with an induction heating coil etc. (same as induction heating means), this invention is not limited to this, It does not equip with an induction heating coil etc. Other heating means (gas combustion, energizing heater, etc.) may be provided instead of the one or the induction heating coil. At this time, the shape of the top plate changes.

Next, an example of the heat generation mechanism of the high-temperature smoke removal unit 40 will be described with reference to FIG.
(Heat generation mechanism of high-temperature smoke removal part 1)
2A, the high-temperature smoke removal unit 40a includes a conductive material 41 having air permeability disposed inside the smoke exhaust passage 30, an electrode 42 for directly energizing the conductive material 41, an electrode Electrical circuit means 43 (power supply, wiring and control means) connected to 42.
The conductor material 41 is not particularly limited. However, the conductor material 41 has a configuration in which the surface area ratio (surface area / volume) such as a mesh or a fin is typified by a heat exchanger and has a resistance value of several hundred Ω. What was adjusted so that it may become back and forth is desirable.

If it does so, resistance heat_generation | fever will arise by applying a power supply voltage to the conductor material 41, and the smoke which passes can be heated.
For example, if the conductor material 41 is formed of a foam metal, air can pass through the interior, the processing is easy, and the foaming rate can be freely changed. The pressure loss can be optimized for the roaster.
The configuration of the electric circuit means 43 is not limited, and even if it is controlled corresponding to the operation of the roaster, the temperature of the passing gas (including smoke) is measured and controlled. Alternatively, the user may set the energization timing.

(Heat generation mechanism of the high temperature smoke removal part 2)
In FIG. 2B, the high-temperature smoke removal unit 40 b directly energizes each of the sheets 44 and the thin wire knitted sheets 44 (plural sheets) knitted with resistance wires disposed inside the smoke exhaust passage 30. Distribution electrode 45 and electric circuit means 46 (power supply, wiring and control means) connected to the distribution electrode 45. That is, a thin wire braided sheet 44 is arranged in place of the conductor material 41 formed of foam metal.
Therefore, since an inexpensive resistance wire can be arranged according to the gap inside the smoke exhaust passage 30, the smoke exhaust can be efficiently heated. The method of weaving the resistance wire is not limited, and may be a net shape forming a lattice, a ladder shape arranged in parallel, a randomly intertwined shape, or the like. Further, the number of the thin wire braided sheets 44 is not limited to a plurality, and may be one.

(Heat generation mechanism of the high-temperature smoke removal part 3)
In FIG. 2C, a magnetic material 47 is disposed in the high-temperature smoke removal unit 40c so as to be freely ventilated, a coil 48 is disposed around the magnetic material 47, and an electric current for supplying a high frequency current to the coil 48 is provided. Circuit means 49 is connected.
Accordingly, since the magnetic material 47 is heated by electromagnetic induction, the gas (including smoke) that passes through the high temperature smoke removal unit 40c is heated. At this time, since the heat generation is induction heating, fine temperature control is possible, and deterioration of the material and excessive energy consumption due to excessive temperature can be suppressed.
The form of the magnetic material 47 is not limited, and any of a cylindrical body, a honeycomb body, a foam, a sheet (net) in which magnetic wires are knitted, a magnetic wire randomly collected, etc. There may be.

[Embodiment 2: Catalyst for flue gas]
FIG. 3 is a cross-sectional view in side view showing the whole, schematically explaining the heating cooker according to Embodiment 2 of the present invention. In addition, the same code | symbol is attached | subjected to this same part as Embodiment 1 (FIG. 1), and one part description is abbreviate | omitted.
In FIG. 3, in the cooking device 200, the smoke removal catalyst 50 is installed on the downstream side (close to the exhaust port 12 a) of the smoke removal passage 30 with respect to the high temperature smoke removal unit 40. For this reason, since the exhaust gas catalyst 50 is exposed to the gas (including smoke) that has passed through the high temperature dehumidifying unit 40, it is heated and activated by the gas (for example, heated to 600 ° C. or more). Therefore, the oxidation reaction is promoted.
That is, the smoke generated in the roaster cabinet 20 is oxidized in the double oxidation reaction section of the high temperature dehumidifying section 40 and the smoke exhausting catalyst 50, and therefore is efficiently defrosted. Further, since the temperature necessary for activating the exhaust gas catalyst 50 is about 350 ° C. or higher, it is not necessary to provide a dedicated heater for heating the exhaust gas catalyst 50.

[Embodiment 3: Mixed air passage section]
FIG. 4 is a side sectional view showing the whole of the heating cooker according to the third embodiment of the present invention. In addition, the same code | symbol is attached | subjected to this same part as Embodiment 1 (FIG. 1), and one part description is abbreviate | omitted.
In FIG. 4, a main body air inlet 31 for taking in air inside the main body 10 is formed on the downstream side (near the exhaust port 12a) of the high temperature smoke removal section 40 of the smoke exhaust passage 30 of the heating cooker 300, An exhaust fan 32 is installed on the downstream side (near the exhaust port 12a) from the air inlet 31.

  A mixed air passage portion is formed in which the smoke discharged from the roaster cabinet 20 and the air flowing in from the main body air inlet 31 can be mixed. At this time, the former is a high temperature, whereas the latter is a relatively low temperature after circulating (venting) the inside of the main body 10 and cooling the equipment (control board, etc.) in the main body 10. The temperature is diluted and discharged from the exhaust port 12a with the temperature lowered. Therefore, the periphery of the cooking device 300 (for example, a kitchen wall or a ceiling) is not exposed to the high-temperature gas (which has been smoked).

[Embodiment 4: Non-drive fan]
FIG. 5 is a side sectional view showing the whole of the heating cooker according to the fourth embodiment of the present invention. In addition, the same code | symbol is attached | subjected to this same part as Embodiment 1 (FIG. 1), and one part description is abbreviate | omitted.
In FIG. 5, a non-drive fan 33 is installed in the smoke exhaust passage 30 of the heating cooker 400. That is, the non-drive fan 33 includes a rotary shaft 33b that is rotatably installed through the wall surface of the smoke exhaust passage 30, and a smoke exhaust passage fixed to the inner side end of the smoke exhaust passage 30 of the rotary shaft 33b. It has a blade 33a and a main body inner blade 33c fixed to the outer side end portion (same as the inside of the main body 10) of the smoke passage 30 of the rotating shaft 33b.
Therefore, when the main body inner wing 33c is rotationally driven by the air flowing inside the main body 10, the smoke exhaust passage inner wing 33a is rotated. Therefore, since the smoke exhaust passage inner blade 33a is rotated without installing a dedicated drive motor, the manufacturing cost and the operating cost can be suppressed.
In the case of the conventional exhaust fan, the temperature of the drive motor itself is increased due to heat transfer from the blades and the heat generated by the drive motor itself, which causes a failure. Therefore, a stable operation can be performed by the non-driving fan even in the high temperature environment.

[Embodiment 5: Double tube structure]
FIG. 6 is a cross-sectional view in side view showing the whole schematically explaining the heating cooker according to the fifth embodiment of the present invention. In addition, the same code | symbol is attached | subjected to this same part as Embodiment 1 (FIG. 1), and one part description is abbreviate | omitted.
In FIG. 6, the heating cooker 500 has a smoke exhaust passage 30 a whose upstream portion has a double tube structure. That is, the smoke exhaust passage 30a includes an outer tube 61 that surrounds the vent 23a of the roaster cabinet 20 and is fixed to the back surface 23, an intermediate tube 62 that is inserted into the outer tube 61 and is fixed to the back surface 23, and an intermediate tube. An inner tube 63 having one end inserted into 62 and the other end communicating with the exhaust port 12a; an inner / outer blocking plate 64 fixed to the inner tube 63 by closing the end surface of the outer tube 61 near the exhaust port 12a; And an inner closing plate 65 for closing the end face of the 62 near the vent 23a. And the high temperature smoke removal part 40 is installed in the upstream of the inner pipe 63 (near the vent hole 23a).

Therefore, the smoke that has passed through the vent 23a and has flowed into the gap between the outer tube 61 and the middle tube 62 has its flow direction changed by the inner and outer blocking plates 64, and flows into the gap between the middle tube 62 and the inner tube 63, Further, the flow direction is changed by the inner closing plate 65 and flows into the inner pipe 63.
For this reason, since the outer surface of the inner pipe 63 in which the high temperature desmoking section 40 is installed is not directly exposed to the air flowing through the main body 10, the temperature reduction of the high temperature desmoking section 40 can be prevented. Furthermore, since the heat leaked from the high temperature smoke removal unit 40 is transmitted to the inner / outer blocking plate 64 and the outer tube 61, the smoke before flowing into the high temperature smoke removal unit 40 is preheated, so that the smoke can be efficiently heated. And the oxidation reaction can be promoted.

[Embodiment 6: Smoke exhaust passage having an inclined portion]
In the structures of the first to fourth embodiments, the temperature of the high-temperature smoke removal unit 40 is very high compared to the inside of the roaster cabinet 20 and the object to be heated. It is expected that the ratio of radiant heat transfer from the high-temperature smoke removal unit 40 will increase and cause uneven burning. The sixth embodiment solves the above problem.
FIG. 7 is a cross-sectional view in side view showing the whole schematically explaining the heating cooker according to the sixth embodiment of the present invention. In addition, the same code | symbol is attached | subjected to this same part as Embodiment 1 (FIG. 1), and one part description is abbreviate | omitted.
In FIG. 7, the cooking device 600 has a smoke discharge passage 30b that is substantially letter-shaped or J-shaped in a side view. That is, the flue gas passage 30b communicates with the vent hole 23a of the roaster cabinet 20 and descends toward the downstream side, the folded portion 35 linked to the inclined portion 34, and the folded portion 35. And a vertical portion 36. The vertical portion 36 communicates with the exhaust port 12a.

Further, since the high-temperature smoke removal unit 40 is installed in the inclined portion 34, the angle formed by the end surface of the high-temperature smoke removal unit 40 on the roaster cabinet 20 side and the upper surface 22 of the roaster cabinet 20 is an acute angle. Therefore, the high-temperature smoke removal unit 40 is structured not to be exposed to the roaster cabinet 20, and the radiant heat from the high-temperature smoke removal unit 40 is radiated to the upper surface 22.
That is, since the radiant heat from the high temperature smoke removal unit 40 is not radiated to the wire mesh 24 side, the generation of local radiant heat transfer is suppressed, and the object to be heated can be heated uniformly. Therefore, it is possible to prevent baking unevenness from occurring in the fish or the like placed on the wire mesh 24.

[Embodiment 7: Heat shield]
FIG. 8 is a cross-sectional view in side view showing the whole schematically explaining the heating cooker according to the seventh embodiment of the present invention. In addition, the same code | symbol is attached | subjected to this same part as Embodiment 1 (FIG. 1), and one part description is abbreviate | omitted.
In FIG. 8, the heating cooker 700 is provided with a heat shield plate 25 that covers the vent 23 a in a freely ventilated manner at a position near the back surface 23 in the roaster cabinet 20. Further, the heat shield plate 25 is provided with first temperature detecting means 71 for estimating the temperature of the high temperature smoke removal unit 40, and detects the temperature of the exhaust gas near the exhaust port 12 a of the smoke passage 30. A temperature detecting means 72 is installed.

That is, since the heat shield plate 25 is provided between the high temperature smoke removal unit 40 and the wire mesh 24 of the roaster cabinet 20, the high temperature smoke removal unit 40 is arranged only at the same height as the wire mesh 24 in design. Even if it is not possible to radiate heat, the heat shield plate 25 is interposed between the high-temperature smoke removal unit 40 and the wire mesh 24 to prevent direct radiant heat transfer from being radiated. Can be heated uniformly.
Moreover, when the temperature detection of the high temperature desmoking part 40 is performed directly, since it is very high temperature, the detection means fixing method when including reliability is technically difficult. Therefore, by providing the first temperature detection means 71 on the heat shield plate 25 that receives only radiant heat transfer, the temperature of the high-temperature smoke removal unit 40 can be estimated in a pseudo manner.

In addition, in the case of the heating cooker 500 (refer to Embodiment 5 and FIG. 6) having a double-pipe structure, if the first temperature detecting means 71 is installed on the inner closing plate 65, similarly, a pseudo high-temperature smoke removal is performed. The temperature of the part 40 can be estimated.
Further, in the case of a heating cooker 600 (see Embodiment 6, FIG. 7) having an inclined tube structure,
Since the radiant heat from the high-temperature smoke removal unit 40 is not directly radiated to the wire mesh 24, a temperature measuring plate (not shown) is provided at a position where the radiant heat is irradiated instead of the heat shield plate 25, and the temperature detecting plate has a first temperature detecting means. 71 may be installed.

[Embodiment 8: Oxidant generator]
FIG. 9 is a side sectional view showing the whole of the heating cooker according to the eighth embodiment of the present invention. In addition, the same code | symbol is attached | subjected to this same part as Embodiment 1 (FIG. 1), and one part description is abbreviate | omitted.
In FIG. 9, a heating cooker 800 is obtained by installing an oxidant generating unit 80 in the flue gas passage 30 in place of the high-temperature smoke removal unit 40 included in the heating cooker 100 (Embodiment 1). The oxidant generator 80 has an opposing electrode pair 81 and electric circuit means 82 (power supply, wiring and control means) connected to the electrode pair 81.
That is, since smoke removal is an oxidation reaction, smoke is oxidized by an oxidant such as ozone or hydrogen peroxide generated by the oxidant generator 80 instead of activation by high temperature.
As an effect, since an oxidation reaction can be performed at a temperature lower than that of the catalyst, it is possible to avoid the thermal influence on the object to be heated and peripheral devices.

  In addition, this invention does not limit the structure of the oxidizing agent production | generation part 80, As long as an oxidizing agent can be produced | generated, any format may be sufficient. In addition, if the inner wall surface of the oxidant generator 80 is surface-treated with an antioxidant, deterioration due to rusting or the like can be suppressed. That is, the oxidant generator 80 is a box (cylinder) usually formed of a metal such as stainless steel, but when used in an oxidized state in which the oxidant is generated for a long time, rusting or the like occurs. There was a possibility. Moreover, the point of the surface treatment by the antioxidant is not limited, and for example, it can be configured to prevent surface corrosion even in an oxidizing substance atmosphere by enamel processing or the like.

  The present invention is not limited to various cookers for business and home use that include a roaster cabinet, but also a cooker having only a roaster (such as a dedicated fish roaster), and a heating element, a gas burner, and dielectric heating at a position other than the roaster. It can be widely used as various induction heating cookers in which means are arranged.
