Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking device (roasting meat for roasting meat) that internally treats smoke generated from a cooking product during cooking.

[0002]

2. Description of the Related Art A conventional cooking device (roasting meat for roasting meat) will be described with reference to FIGS.

FIG. 8 is a sectional view of a conventional cooker, FIG. 9 is a partially cutaway perspective view, and FIG. 10 is an electric circuit diagram.

As shown in the figure, the conventional cooker sucks smoke generated during cooking, and an intake port 1 formed on the outer periphery of a cooking section E disposed on the upper surface of the cooker main body A, and a suction port 1 A smoke purifying device 2 for purifying the contained smoke, and a gas liquefying device 3 for liquefying an eye irritating gas (aldehydes) in the exhaust gas purified by the smoke purifying device 2 with a treatment solvent B.
And a fan 5 for forming an air flow from the intake port 1 through the gas liquefaction device 3 to the exhaust port 4.

The smoke purifying device 2 is composed of a rectifier 2a and a dust collector 2b arranged in a lateral direction, and the rectifier 2a has a function of adhering oil smoke having a relatively large particle size to its wall surface. The dust collector 2b generates corona discharge and has a function of treating relatively small oil particles and smoke particles. 2c is a dust collecting electrode for charging smoke particles.

The gas liquefying device 3 has a box 3b having an inlet 3a connected to the outlet of the smoke purifying device 2, a treatment solvent B for dissolving the eye irritating gas, an exhaust containing the treatment solvent B and the eye irritating gas. A contact material D that increases the contact surface with C and a circulating pump P that repeatedly supplies the processing solvent B to the contact material D in a shower shape are provided.

When the processing solvent B in the solvent tray 20 falls below a certain level L, for example, 15 mm from 40 mm, the circulation pump P is automatically turned off and the buzzer 26 is turned on to keep the processing solvent B in the tank 19. In order to inform the user of the replenishment, the float 27, its lifting guide 28, the interlocking levers 29, 30 of the float 27, and the levers 29, 30
A float switch 31 that is turned on / off by the operation of is provided.

In the figure, 13 is a gas inlet for joining with a gas pipe, 14 is a gas cock arranged on the side of the rustle 6a, 15 is a fan 5 and an ON-OF for the smoke purifying device.
F is an electric switch operated, 16 is a top plate, 17 is a leg that also serves as an adjuster for adjusting the levelness of the main body, and 18 is an oil pan.

In the above structure, smoke (including oil droplets, oil smoke, and eye irritating gas) generated from the food to be cooked on the roast 6a is sucked from the intake port 1 while being mixed with the room air, and is sucked into the intake passage 8. It enters and is guided to the entrance 2d of the smoke purification device 2.

Here, in the rectifier 2a of the smoke purifying device 2, oil droplets having a large particle diameter are attached to the wall surface thereof, and in the dust collector 2b, smoke having a small particle diameter is sucked into the dust collecting portion and passes through the corona discharge. Then, the smoke particles are charged and attached to the dust collecting electrode 2c.

The exhaust gas that has passed through the smoke purifying device 2 and from which oil drops and oil smoke have been removed passes through the outlet 2e of the smoke purifying device 2 and the fan 5, and is introduced into the box 3b from the inlet 3a of the gas liquefying device 3. .

Further, since the processing solvent B is stored in the processing solvent tank 19 and the processing solvent B having a constant level L is always kept in the solvent tray 20, the circulation pump P stores the processing solvent B in the solvent tray 20. The suction solvent is repeatedly pumped to the hose 22, the processing solvent B at the outlet 22a of the hose is supplied to the sprayer 24 having the perforated plate 23, and the processing solvent B in the shower form is the contact material D.
It takes a long time to flow down the surface. During this time, the eye irritating gas is sufficiently in contact with the treatment solvent B, and 70 to 80% of the eye stimulating gas becomes a solution and is accumulated in the solvent dish 20.

The clean exhaust gas (exhaust gas from which the eye irritating gas has been removed) exiting the case 25 is discharged from the exhaust port 4 to the outside.

As described above, since the smoke particles and the oil droplets can be removed at the same time as the eye irritating gas can be removed, the eye irritating gas is not processed and is not discharged as it is to the room. No symptoms such as eye pain even when used.

[0015]

However, in the conventional cooking device, as shown in FIG. 8, high-temperature clean exhaust gas is discharged from the exhaust port 4 provided on the side of the main body, so that this clean exhaust gas is unexpected. There is a risk that the user may hit the user from an unsealed position and may feel uncomfortable or burn the user. In order to prevent this, a new cooling device is required, which increases the cost.

Further, since the smoke purifying device 2 and the gas liquefying device 3 are provided in the main body for internally treating the smoke generated during cooking, the cost is increased and the size is increased.

Furthermore, since oil droplets and oil smoke adhere to the rectifier 2a and the dust collector 2b, it is necessary to regularly clean or replace them. However, the exchange door 12 is opened and the smoke purifying device 2 and the gas liquefying device 3 are opened. The replacement work is complicated because the unit must be pulled out before it can be replaced.

In view of the above, it is an object of the present invention to provide a small-sized cooker capable of safely and inexpensively treating smoke generated during cooking inside.

[0019]

As shown in FIGS. 1 to 3 and 5 to 7, an object of the present invention is to provide an outer box 51 disposed inside a cooker main body 50 and an intake port for the outer box 51. An inner box 53 that is internally formed to form 52, a heating unit 54 that is disposed in the inner box 53 to heat a food item, and a cooking table 55 that is supported by the inner box 53 above the heating unit 54. And a chimney 56 detachably mounted on the cooking table 55, one end of which is connected to the bottom surface of the outer box 51 and the other end of which is heating means 54.
A duct 57 connected to the side of the inner box 53 on the lower side.
And the chimney 56 through the duct 57 from the intake port 52.
And a fan 58 for forming an air flow to reach the inside of the chimney 56. The chimney 56 is filled with a catalyst 59 for treating smoke generated from the food during cooking.

[0020]

In the means for solving the above problems, the cooking table 55
The smoke generated from the cooked food of the
It is guided from 2 to the duct 57, passes through the duct 57, is discharged to the inner box 53, and then reaches the chimney 56. Where the smoke is
By coming into contact with the catalyst 59 in the chimney 56, oil drops, oil smoke and eye irritating gas are removed to produce clean exhaust gas, which is discharged from the chimney 56 to the outside.

At this time, the catalyst 59 is constantly heated to 300 to 50 by the heating means 54 so that the activation capacity can be sufficiently exhibited.
It is heated to 0 ° C, and the discharge part 65 of the duct 57 is
Since the smoke discharged from the exhaust gas reaches the chimney 56 after being heated by the heating means 54, the eye irritating gas which is particularly difficult to remove can be efficiently removed.

Therefore, since the smoke can be internally treated without providing the smoke purifying device and the gas liquefying device as in the conventional case, it is possible to provide a small-sized and inexpensive cooker having a smoke treating ability.

Further, since the clean exhaust gas is discharged from above, the user can always see the discharge of the clean exhaust gas, and it is not necessary to provide a cooling device in consideration of safety and the like.

Further, since oil drops, oil smoke and the like adhere to the catalyst 59, it is necessary to regularly clean or replace the catalyst 59. At this time, the chimney 56 should be detachable from the cooktop 55. This simplifies replacement work and the like.

[0025]

Embodiments of the present invention will be described below with reference to the drawings.

<First Embodiment> FIG. 1 is a sectional view of a cooker according to a first embodiment of the present invention, FIG. 2 is a plan view thereof, and FIG. 3 is a right side view thereof.

As shown in the drawing, the cooking device (roasting meat for roasting meat) of this embodiment includes an outer box 51 arranged inside a cooking device main body 50.
An inner box 53 installed to form an intake port 52 in the outer box 51, a heating means 54 arranged in the inner box 53 for heating a cooking product, and supported by the inner box 53 above the heating means 54. Cooked food table 55, a chimney 56 detachably attached to the cooked food table 55, one end communicated with the bottom surface of the outer box 51, and the other end below the heating means 54 and the inner box 53. And a fan 58 that forms an air flow from the intake port 52 through the duct 57 to the chimney 56. The duct 57 is formed in the chimney 56 from the food to be cooked during cooking. It is filled with a catalyst 59 for treating the smoke.

In the figure, 60 is a top plate.

The outer box 51 is formed in a cylindrical shape with a bottom, and a flange 51a that engages with the top plate 60 is provided on the outer periphery of the upper part thereof.

The inner box 53 is formed in a bottomed cylindrical shape smaller than the outer box 51 so as to form the intake port 52, and is supported by a discharge portion 65 of a duct 57 which will be described later.

The heating means 54 is a ring-shaped electric heater for efficiently guiding smoke to the chimney 56 while heating the smoke discharged from the duct 57. The heater 54 is provided between the outer box 51 and the inner box 53. It is detachably connected to the inserted connector 61.

The food placing table 55 is composed of a rustle 62 on which the food is placed and a broth receiver 63 arranged below the rustle 62. The rostrut 62 is formed in a disk shape having a central circular hole 62a and a plurality of long holes 62b for dropping the gravy provided around the central circular hole 62a. Further, the broth receiver 63 is a ring larger than the heater 54 so that the heat generated from the heater 54 is directly transmitted to the cooked food on the rustle 62 and the smoke from the duct 57 heated by the heater 54 is guided to the chimney 56. A flange 63a that is detachably engaged with the inner box 53 is provided on the outer periphery of the flange 63a.

The chimney 56 is formed into a bottomless cylindrical shape, and the lower end thereof is fitted and held in the central circular hole 62a of the loss 62. The fitting portion has a smaller diameter than the catalyst filling portion so as to prevent the catalyst 59 from coming out downward.

The duct 57 has a suction portion 64 for sucking the smoke generated from the food from the suction port 52, and the suction portion 64.
And a discharge part 65 for discharging the smoke to the inner box 53. A grease filter 66 for removing oil mist when inhaling smoke is provided at a connecting portion between the suction portion 64 and the outer casing 51.

The fan 58 is a blower (Shirotsuko fan), and is arranged at the connecting portion between the suction portion 64 and the discharge portion 65.

The catalyst 59 is a perovskite catalyst which is excellent in heat resistance and has a high activity equal to or higher than that of a noble metal catalyst, and it is formed in a cylindrical shape by a ceramic Hankham as a carrier.

In the above structure, the smoke generated from the food on the rest 62 of the food placing table 55 is guided from the intake port 52 to the duct 57 by the fan 58. At this time, the oil mist is removed by the grease filter 66 arranged at the connecting portion between the outer case 51 and the suction portion 64 of the duct 57.

The smoke from which the oil mist has been removed passes through the duct 57 and is discharged to the inner box 53, and then reaches the chimney 56. Here, the smoke comes into contact with the catalyst 59 in the chimney 56 to remove oil droplets, oil smoke, and eye irritating gas mainly composed of aldehydes such as formaldehyde, acetaldehyde, and agrolein, and becomes clean exhaust gas. 5
6 is released to the outside.

At this time, the catalyst 59 is constantly heated to 300 to 50 by the heating means 54 so that the activation ability can be sufficiently exhibited.
It is heated to 0 ° C, and moreover, from the intake port 51 to the duct 5
Since the smoke passing through 7 is also heated by the heating means 54 and reaches the chimney 56, the eye irritating gas which is particularly difficult to remove can be efficiently removed.

Table 1 shows the formaldechtino removal data according to this example.

[0041]

[Table 1]

As described above, the chimney 56 filled with the catalyst 59.
Is attached to the cooking table 55, and the smoke discharged from the catalyst 59 and the duct 57 is constantly heated by the heating means 54.
Since it is configured to internally treat smoke generated from cooked food, the smoke can be internally treated without providing a smoke purifier and a gas liquefaction device as in the conventional case. A cooker having the ability can be provided.

Here, as in the example of the proposal shown in FIG. 4, it is conceivable to arrange the catalyst 59 and the auxiliary heater 70 in the duct 57 to internally treat the smoke generated from the food. However, in the configuration of the proposed example, when the clean exhaust gas that has been internally treated at all is discharged to the outside, it is mixed with smoke that is not internally treated. In order to prevent this, it is necessary to provide a discharge port on the side portion of the main body for discharge as in the conventional case. For this reason, it is necessary to newly provide a cooling device in consideration of safety for the user, resulting in high cost.

On the other hand, in this embodiment, since the clean exhaust gas is discharged from above, the discharge of the clean exhaust gas is always visible to the user, and it is not necessary to provide a cooling device in consideration of safety and the like.

Further, since oil drops, oil smoke, etc. adhere to the catalyst 59, it is necessary to wash or replace it regularly.
Also in this case, the chimney 56 can be attached to and detached from the cooking table 55, so that the replacement work and the like can be simplified.

<Second Embodiment> FIG. 5 is a sectional view of a cooker according to a second embodiment of the present invention, FIG. 6 is a plan view of the same, and FIG. 7 is a right side view of the same.

As shown in the figure, in this embodiment, the cooking table 5 is used.
5 is the same as the wire mesh 80 with the central circular hole 80a and the central circular hole 63
It is composed of the meat juice receiver 63 with a, and the chimney 56 is penetrated through the central circular hole 80a of the wire mesh 80 and the central circular hole 63 of the meat juice receiver 63.
It is removably fitted to a, and other configurations, operations, and effects are the same as those in the first embodiment.

The present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

[0049]

As is apparent from the above description, according to the present invention, the outer box disposed inside the cooker main body, the inner box internally provided to form the intake port in the outer box, and the inner box are provided. A heating means for arranging and heating the cooked food, a cooking food placing table supported by the inner box above the heating means, a chimney detachably attached to the cooking food placing table, and one end communicating with the bottom surface of the outer box. The inside of the chimney is equipped with a duct that is connected to the other end of the inner box and is connected to the side of the inner box below the heating means, and a fan that forms an air flow through the duct from the intake port to the chimney. At times, it is configured to be filled with a catalyst for treating smoke generated from the cooked product, and the smoke emitted from the catalyst and the duct is always heated by the heating means to internally treat the smoke generated from the cooked product. Therefore, it is possible to eliminate smoke without installing a smoke purification device and a gas liquefaction device as in the past. Since it is possible to part processing, it can provide a cooker having a small and inexpensive smoke capacity.

Further, since the clean exhaust gas is discharged from above, the user can always see the discharge of the clean exhaust gas, and it is not necessary to provide a cooling device in consideration of safety and the like.

Further, since oil droplets, oil smoke, etc. adhere to the catalyst, it is necessary to regularly clean or replace the catalyst. In this case as well, the chimney can be attached to and detached from the cooking table so that the catalyst can be replaced. Work becomes easy.
