Description

  The present invention relates to a grill for purifying smoke generated from an object to be cooked.

2. Description of the Related Art Conventionally, grills are known that are designed to eliminate smoke and no bromide of smoke generated from an object to be cooked. For example, a grill proposed in Patent Document 1 (Actual 6-3298) is provided with a perforated plate below a surface combustion burner, and smoke generated from an object to be cooked passes through the perforated plate. Smoke is burned out without providing a dedicated burner for burning, and impurities are oxidized with an oxidation catalyst filter provided at the exhaust port to eliminate smoke and no bromide.
Reality 6-3298

However, in this conventional grill, since the perforated plate is arranged between the burner that emits radiant heat and the object to be cooked, the radiation to the object to be cooked is blocked and the heating to the important object to be cooked is good. I can not do it.
Moreover, since the oxidation catalyst filter provided at the exhaust port cannot be heated to an appropriate temperature, it is not fully activated and cannot perform its purification function. Eventually, the structure which heats an oxidation catalyst filter will be needed.
The grill of the present invention has an object to solve the above problems and to provide a grill that can satisfactorily perform smokeless and bromide without providing a special burner for burning out a catalyst or a burner for heating a catalyst.

The grill according to claim 1 of the present invention that solves the above problems is provided.
A burner that burns fuel gas;
A plurality of heating plates provided above the cooking object and having a lower surface heated by the burner to give radiant heat to the cooking object from above, and smoke generated from the cooking object is formed on the heating plate In the hot plate heating type grill that passes through the hot plate opening of the plate and discharges it outside the container body,
A porous catalyst plate for purifying the smoke that has passed through the hot plate opening is provided facing the hot plate, and an exhaust port is provided at the rear end extending in the front-rear direction above the porous catalyst plate. The gist is to form an exhaust passage, and to send smoke purified through the porous catalyst plate to the rear through the exhaust passage and to be discharged from the exhaust port.

According to the grill of the present invention having the above configuration, the object to be cooked is heated by the radiant heat radiated from the hot plate to generate smoke, but when the smoke rises and reaches the hot plate, it passes through the hot plate opening, During this passage, some smoke and odorous components are burned on the hot plate and disappear, and when they rise and pass through the holes of the porous catalyst plate, the remaining smoke and odorous components are oxidized and smokeless and brominated.
In this case, since the porous catalyst plate is heated by a hot plate provided below, the porous catalyst plate is sufficiently activated and maintains a high purification function.
Thus, the purified smoke is sent rearward on the porous catalyst plate and discharged from the rear exhaust port. Even in the middle of flowing backward in the exhaust passage, the smoke comes into contact with the porous catalyst plate and is smokeless and brominated.
Therefore, smokeless and bromide can be efficiently performed with a simple configuration without using a dedicated burner for burning out smoke or a dedicated burner for heating the catalyst plate.
In addition, since a porous catalyst plate is interposed between the hot plate and the body top plate, to prevent the heat of the hot plate from being transmitted to the body top plate, the temperature rise of the body top plate is suppressed and safe. It is.
Furthermore, since the purified exhaust gas is discharged from the rear side of the container body, the exhaust gas does not flow out to the cooker side and can be used comfortably compared to a grill of the type that exhausts from the center of the upper surface of the container body.

  In order to further clarify the configuration and operation of the present invention described above, a preferred embodiment of the grill of the present invention will be described below.

  FIG. 1 is a schematic front view showing the inside of a gas grill mounted on a gas table stove as an embodiment, and FIG. 2 is a schematic side view of the gas grill.

  The gas grill includes a grill box 1 that accommodates an object to be cooked F to form a cooking space, a burner 2 that is provided on the upper left and right sides of the grill box 1 and burns fuel gas, and covers the entire upper side of the grill box 1. 2 is connected to the hot plate 3 that is heated by the flame of 2 and emits radiant heat, the grill 5A on which the cooking object F is placed below the grill cabinet 1, and the soup pan 5 that is connected to the front of the grill pan 1. And a grill door 6 that covers the door in an openable and closable manner.

Further, above the hot plate 3, a grille is provided so that a porous catalyst plate 4 for purifying smoke generated from the cooking object F covers the entire hot plate 3 in a substantially horizontal direction at a predetermined interval from the hot plate 3. It is provided from the front end of the storage 1 to the rear end.
Above the porous catalyst plate 4, a ceiling surface 7 of the grill cabinet 1 is formed at a predetermined interval, and this space functions as an exhaust passage 8. And the exhaust port 9 which discharges | emits exhaust_gas | exhaustion outside the store | warehouse | chamber is formed in the rear end of the ceiling surface 7 of the grill warehouse 1 upwards.
Further, a body top plate 10 (top plate) is provided above the grill ceiling surface 7, and an opening through which the exhaust port 9 faces is formed at the rear end thereof.

The hot plate 3 is formed by pressing a single metal plate, and the opening 3A through which smoke generated from the combustion exhaust of the burner 2 and the food F is passed upward (hereinafter referred to as hot plate opening 3A). Is formed in a louver shape.
The porous catalyst plate 4 provided above the hot plate 3 is an oxidation catalyst such as platinum on a heat-resistant ceramic plate in which a plurality of openings 4A (hereinafter referred to as catalyst openings 4A) having a size that does not increase the exhaust resistance is formed. The upper part in the grill box 1 is horizontally partitioned, and all of the generated exhaust gas passes through the catalyst opening 4A.

Next, the smoke purification mechanism of this grill will be described.
When the user operates an ignition button (not shown) to ignite the burner 2, the flame of the burner 2 comes into contact with the hot plate 3 and the hot plate 3 is heated. By this heating, the hot plate 3 radiates radiant heat toward the cooking object F and heats the cooking object F.
When the food F is thus heated, smoke is generated from the food F. This smoke rises above the grill 1 and passes through the hot plate opening 3 </ b> A together with the combustion exhaust of the burner 2. At this time, some smoke and odor components are burned out and lost due to contact with the hot plate 3.
Further, the exhaust gas that has passed through the hot plate opening 3A is sent upward and passes through the catalyst opening 4A. At this time, since the porous catalyst plate 4 is sufficiently heated by receiving radiant heat from the hot plate 3, its purification ability is sufficiently maintained, and the remaining smoke and odor components contained in the exhaust are Disappears due to the oxidizing action. The odorless and smokeless exhaust gas flows backward between the grill ceiling surface 7 and the upper surface of the catalyst plate 4 and is discharged out of the appliance through the exhaust port 9.
Even during the flow through the exhaust passage 8, the exhaust is in contact with the upper surface of the porous catalyst plate 4, so that even if smoke or odorous components remain in the exhaust, the purification action also works here to make it odorless and smokeless.

As described above, according to the grill of this embodiment, the upper part of the grill cabinet 1 is divided up and down by the porous catalyst plate 4 having substantially the same size as the hot plate 3, and the exhaust passage 8 is formed in the upper part thereof, so that all exhaust Is allowed to pass through the catalyst openings 4A of the porous catalyst plate 4, so that an exhaust purification action can be obtained very well. Moreover, since the entire porous catalyst plate 4 is activated using the heat of the hot plate 3, a dedicated burner for activation is not required, and the configuration is simplified.
In addition, since the porous catalyst plate 4 is interposed between the hot plate 3 and the vessel top plate 10, the heat of the hot plate 3 is prevented from being transmitted to the vessel top plate 10, and the temperature of the vessel top plate 10 is increased. The rise is suppressed and safe.
Furthermore, since the heat of the hot plate 3 is directly radiated to the cooking object 3 without being interrupted, good cooking can be performed.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention.
For example, the porous catalyst plate 4 may cover a part of the grill cabinet 1.

  The present invention can be applied not only to gas appliances incorporating a grill such as a gas table stove and gas built-in stove, but also to a cooker having a single grill such as a fish grill.

It is a front schematic block diagram of the gas grill as one Example. It is a side schematic block diagram of the gas grill as an example.
