Description

  The present invention relates to a heating cooker for deodorizing (desmoking) smoke and odor generated from a cooking device such as a grill by a deodorizing catalyst, a deodorizing device thereof, and a filter unit for the deodorizing device.

  In a cooking device such as a grill, for example, a large amount of smoke and odor is generated during cooking such as grilled fish, so how to decompose and purify the smoke and odor is a major issue. In recent years, various cooking devices having a deodorizing catalyst for purifying smoke and odor have been developed. As such a deodorizing catalyst, a catalyst that is activated by being heated to 300 to 400 ° is widely used, and is generally formed so that the deodorizing catalyst has an area that blocks the exhaust air passage alone. In the vicinity thereof, a catalyst heater is arranged (for example, see Patent Document 1).

The bifurcated leg (striate body) is arranged so as to be parallel to the surface of the deodorizing catalyst. However, since the heat action of the sheathed heater is weakened in inverse proportion to the distance, a deodorizing catalyst having an area that fills the cross section of the exhaust air passage by itself becomes inevitably wide with respect to the heater and becomes U-shaped. Although depending on the direction of the catalyst heater (seeds heater), heat is not sufficiently supplied to the gap between the forked legs (striate body) of the heater, and the activation of the surface of the deodorizing catalyst in these parts is sufficient. Sometimes it was not done. In such sites, the deodorization catalyst activation reaction is lowered, the original deodorization / deodorization performance is lowered, and the smoke and odor are intensively removed from the part where the deodorization catalyst is not fully activated. was there.

  The present invention has been made in view of the above-described problems, and stabilizes the activation of a deodorization catalyst in a heating cooker and can exhibit good deodorization / deodorization performance, and a deodorizing device and filter for the deodorizing device.

In preparation. When the blower is operated, the outside air introduced into the body case 2 1 from the air inlet 6 air-cools the heating parts such as the electromagnetic induction heater and the substrate, the top plate 2 and other heated parts. The air is discharged from the exhaust port 7a at the rear of the main body to the outside of the main body.

  Next, the cooking device, that is, the grill 8 and the deodorizing device 30 will be described with reference to FIGS. 1 to 8 and FIG. 10 described later. As shown in FIG. 10, the grill 8 has an oil receiver 22 that receives oil components and the like detachably installed at the bottom of the heating chamber 21, and a heated object 24 such as a fish is placed on the oil receiver 22. A wire mesh 25 is arranged. An upper grill heater 26 is disposed in the upper portion of the heating chamber 21, and a lower grill heater 27 is disposed between the wire mesh 25 and the oil receiver 22.

  The deodorizing device 30 is connected to the heating chamber 21 to form the exhaust air passage 31 and the casing 32 shown in FIGS. 3 to 6, and the ventilation area substantially equal to the cross-sectional area of the exhaust air passage 31 (excluding the inlet portion). It comprises a deodorizing catalyst 35, 35 having a portion, a catalyst heater 36, a blower fan 37, and a motor 38 for driving the blower fan 37. In the present embodiment, the catalyst heater 36 is bent in a U shape on the heating chamber 21 side of the deodorizing catalysts 35, 35 so that the bifurcated legs 36a, 36b are parallel to the central axis of the deodorizing catalysts 35, 35, respectively. Is placed close to. The blower fan 37 is attached to the exhaust side of the deodorizing catalysts 35, 35 in the exhaust air passage 31 and is driven by a motor 38 attached to the housing 32.

  Further, the deodorizing catalysts 35, 35 are located far from the catalyst heater 36, and the inlet portion of the exhaust air passage 31 through a spacer 33 made of a heat insulating material such as ceramic as a shielding member that impedes air permeability to a portion that is difficult to be heated. That is, it is formed in a narrow and long shape installed in the intake port 34. In this way, the catalyst at a portion that is far from the catalyst heater 36 and is not easily heated enough to activate the deodorizing catalyst 35 is replaced with a spacer 33 that is a shielding member that impedes air permeability, thereby deodorizing and desmokinging. It is possible to improve performance. In this embodiment, the deodorizing catalysts 35 and 35 are provided in two upper and lower stages as shown in FIGS. Thereby, it is not necessary to process the deodorizing catalyst 35 into a complicated shape, and productivity is improved. Furthermore, in this embodiment, the peripheral side surfaces of the deodorizing catalysts 35, 35 divided into the upper and lower stages are integrally covered with heat insulating materials 39, 39 such as ceramics, and the spacer 33 is interposed in the metal frame 41. The filter unit is formed into a cartridge by being placed in parallel in two stages. This facilitates handling of the deodorization catalyst, and can improve the assembly of the deodorization apparatus and by extension, the cooking device. As described above, in this embodiment, the deodorizing catalyst 35 is small and long and has a two-stage configuration, so that the catalyst heater 36 can sufficiently heat the entire surface of the deodorizing catalyst 35 to the activation temperature. The activation areas of the surfaces of the deodorizing catalysts 35, 35 are equalized, and the activation of the deodorizing catalysts 35, 35 can be stabilized. In the present embodiment, the deodorizing catalysts 35 and 35 are divided into two upper and lower stages, and the spacer 33 is provided between them. Since the activation of the deodorizing catalysts 35 and 35 can be stabilized if the member is provided, the present invention can be applied without necessarily dividing into two. In this embodiment, the configuration using the spacer 33 as the shielding member is described as an example. However, the present invention is not limited to this, and the shielding member may be provided integrally with the metal frame 41 or the like. Such a part may be shielded by a shape. Furthermore, when such a shielding member has a heat insulating property, the temperature of the heated deodorizing catalyst is not lost, and the deodorizing catalyst can be heated satisfactorily. However, even if the shielding member does not have a heat insulating property, the same effect can be obtained by interposing a heat insulating material or the like between the shielding member and the deodorizing catalyst.

  The catalyst heater 36 is attached and fixed to the back side of the heating chamber 21 as shown in FIG. 6, and the deodorizing catalysts 35, 35, the blower fan 37, and the motor 38 that are made into a cartridge are integrated with the housing 32. As the assembly 42 is mounted so as to be dropped from the upper side behind the catalyst heater 36 on the back side of the heating chamber 21, the catalyst heater 36 and the assembly 42 are separated. It can be assembled as possible. Therefore, a guide (not shown) that guides the deodorizing catalysts 35 and 35 of the assembly 42 in the vertical direction is provided at the catalyst heater 36 mounting portion on the back side of the heating chamber 21. As a result, it is possible to easily remove other components except the catalyst heater 36 having a long life among the components of the deodorizing device 30 and improve the assemblability and maintainability of the deodorizing device.

  The sealing portions 36c and 36d at both ends of the catalyst heater 36 are bent toward the non-heating chamber side to avoid the influence of the heat on the grill heater 26 as shown in FIGS. The terminals 43a and 43b welded and joined to the tips of the sealing portions 36c and 36d are oriented by changing the direction by 90 ° so that they do not overlap vertically. Thereby, the wiring work from the upper part becomes possible, the attachment of the wire to the deodorizing device can be carried out by the stacking method, and the assembling property and the maintainability of the deodorizing device can be improved.

FIG. 9 is an enlarged front view, a plan view, and a side view showing a deodorization catalyst used in a deodorization apparatus for a heating cooker according to Embodiment 2 of the present invention. The same parts are denoted by the same reference numerals.

  In the present embodiment, two deodorizing catalysts 35a and 35a having a small width and a length similar to those described in the first embodiment are integrated with a heat insulating material 39A such as ceramic to form a single deodorizing catalyst 35A filter unit. It is configured. Thereby, handling becomes still easier and the assembling property of the deodorizing apparatus and thus the heating cooker can be improved. Other configurations are the same as those of the first embodiment described above, and all the functions of the first embodiment are provided.

Embodiment 3 FIG.
FIG. 10 is a side sectional view showing a deodorizing apparatus for a heating cooker according to Embodiment 3 of the present invention, and FIG. 11 is a perspective view for explaining the relationship between the exhaust air passage and the heat shield plate which are the main parts. In the drawings, the same parts as those in the first embodiment are denoted by the same reference numerals.

  In the present embodiment, a heat shield plate 50 is provided so as to cover the entire upper surface of the exhaust air passage 31, and a cooling air passage 51 including a gap is formed between the heat shield plate 50 and the upper surface of the exhaust air passage 31. I try to do it. Thereby, the heat of the exhaust air passage 31 can be prevented from being transmitted to the top plate 2, and the exhaust air passage 31 itself can be cooled by the wind passing through the cooling air passage 51 by natural convection. Other configurations are the same as those of the first embodiment described above, and all the functions of the first embodiment are provided.

Embodiment 4 FIG.
FIG. 12 is a side sectional view showing a deodorizing device for a heating cooker according to Embodiment 4 of the present invention, FIG. 13 is an explanatory view of the action of the air volume adjusting plate as the main part, and FIG. 14 heats the air volume adjusting plate. It is a front view shown from the chamber side, and the same code | symbol is attached | subjected to the same part as above-mentioned Embodiment 3 in each figure.

  In the present embodiment, a punching metal, for example, formed of a metal plate or a heat-resistant plastic having a number of small openings on the intake side of the deodorizing catalysts 35, 35 of the exhaust air passage 31, that is, the upper part of the back surface of the heating chamber 21. The total area of the large number of ventilation holes 61 formed in the air volume adjusting plate 60 is the total area of the decomposition holes of the deodorizing catalyst (for example, obtained from the porosity of the deodorizing catalyst). The other configuration is the same as that of the first and third embodiments described above, and has all the functions of the first and third embodiments.

  In the present embodiment, since the air volume adjusting plate 60 having a large number of ventilation holes 61 is arranged on the intake side of the deodorizing catalysts 35, 35, the exhaust flow having smoke from the heating chamber 21 is caused by resistance by the ventilation holes 61. After the wind speed is decelerated, it passes through the decomposition holes of the deodorizing catalysts 35 and 35. For this reason, the time which contacts with the deodorizing catalysts 35 and 35 becomes long, and the capability of decomposing the smoke of the deodorizing catalysts 35 and 35 improves. Furthermore, clogging of the deodorizing catalysts 35, 35 and adhesion of oil components to the catalyst heater 36 can be prevented or reduced.

  Further, since the air speed is reduced by the air volume adjusting plate 60, the heat of the catalyst heater 36 is also difficult to escape from the exhaust hole, and the temperature of the deodorizing catalysts 35, 35 can be reliably increased. The decomposition capability can be further improved, and a temperature drop in the heating chamber 21 can be prevented. For this reason, the energy saving effect is acquired.

  In addition, the heat shielding effect of the air volume adjusting plate 60 can reduce the influence of the heat of the catalyst heater 36 on the heating chamber 21, thereby preventing a partial temperature rise of the heated object in the heating chamber. Can be reduced, and scoring is reduced.

  By the way, when the fish (protein) is baked, the components of the smoke generated are oil mist and water vapor which are mostly composed of hydrocarbons. This oil mist combines with the moisture in the heating chamber 21 which is the generated water vapor, and increases its mass. In the present embodiment, since the moisture in the heating chamber 21 is not easily discharged from the exhaust port by the air volume adjusting plate 60, the oil mist and water vapor generated when the fish is baked are easily combined with each other in the heating chamber 21. The mass can be increased and dropped to the bottom of the heating chamber 21, and the generation of exhaust smoke can be reduced.

  Further, since the air volume adjusting plate 60 is installed at the upper part of the back surface of the heating chamber 21, even if oil components generated from fish or the like adhere to the air volume adjusting plate 60, Since it falls, the cleaning process is easy.

  Further, since the total area of the large number of ventilation holes 61 of the air volume adjusting plate 60 is larger than the total area of the decomposition holes of the deodorization catalysts 35, 35, a flow from the heating chamber 21 to the deodorization catalysts 35, 35 side is necessary. The amount of the deodorizing catalyst 35 can be improved while preventing the smoke from being filled in the heating chamber 21, and the capacity of the deodorizing catalyst 35, 35 can be improved. Since the pressure loss generated at 60 becomes smaller, the exhaust performance is not lowered by providing the air volume adjusting plate.

  In addition, you may perform a deodorizing process or an antibacterial process on the surface of the air volume adjusting plate 60, and in this case, a deodorizing effect can increase more or propagation of various bacteria can be prevented.

  In this embodiment, it is made of, for example, a punching metal or the like made of a metal plate or a heat-resistant plastic having a large number of ventilation holes 61 and having a large number of small openings arranged on the intake side of the deodorizing catalysts 35 and 35. The lower edge portion of the air volume adjusting plate 60A is raised from the back surface of the heating chamber 21 to form an inclined surface 62 that is inclined toward the oil receiver 22 on the bottom surface of the heating chamber 21, and oil components generated from fish and the like are supplied to the air volume adjusting plate. Even if it adheres to 60A, it can be surely dropped into the oil receiver 22, and the other configurations are the same as those in the first and fourth embodiments. And all the functions of the fourth embodiment.

  In the present embodiment, even if oil components or the like generated from fish or the like adhere to the air volume adjusting plate 60A, the oil on the bottom surface of the heating chamber 21 is guided by the inclined surface 62 formed at the lower edge of the air volume adjusting plate 60A. Since it surely falls into the receptacle 22, the cleaning process is further facilitated.

  Also in the present embodiment, the surface of the air volume adjusting plate 60A may be subjected to a deodorizing process or an antibacterial process.
