DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fish roaster in which foods placed in a cooking cabinet are baked one by one by an upper heating element or from both upper and lower sides by an upper and lower heating element.

[0002]

2. Description of the Related Art Conventionally, in a fish roaster of this type, as a method for reducing smoke and odor generated by heating food, a purifying device comprising an oxidation reaction accelerating catalyst is installed at an upper portion or a rear portion of a cooking cabinet, or In some cases, an exhaust fan is provided in the middle of an exhaust passage communicating between a cooking chamber and outside air, and an exhaust fan is connected to the exhaust passage to forcibly exhaust air.

No.)

[0003]

In the purifying apparatus comprising the above-mentioned conventional oxidation reaction accelerating catalyst, the cooking chamber contains a large amount of foodstuffs with fermented products such as miso and soy sauce and a large amount of alcohol such as bread. When the food is heated, the oxidation reaction rate of the gas passing through the catalyst increases as the temperature rises, and the smoke and odor generated from the food are purified into colorless and odorless carbon dioxide and water vapor. There has been a problem that the efficiency of the promoted catalyst is reduced, the gas passing through the catalyst undergoes an incomplete oxidation reaction, and an irritating odor such as acetaldehyde is generated, giving a user discomfort.

[0004]

In order to solve the above-mentioned problems, the present invention provides a purification device in which an oxidation reaction promoting catalyst and an adsorbent catalyst are connected to an exhaust passage communicating between the inside of a cooking chamber and outside air. Or a catalyst having an adsorptive property before and after the oxidation reaction promoting catalyst to provide a fish roaster in which generation of irritating odor is avoided.

[0005]

Are formed by combining.

According to a second aspect of the present invention, the oxidation reaction-promoting catalyst and the adsorptive catalyst are separately provided, and the adsorptive catalyst is provided before or after the oxidation reaction-promoting catalyst.

Thus, the present invention can eliminate the generation of an irritating odor due to the incomplete oxidation reaction of smoke and odor when passing through the purification device.

[0008]

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

In FIGS. 1 and 2, reference numeral 1 denotes a box-shaped cooking cabinet having an open front surface, the periphery of which is covered with an outer shell 13, and inside which heats an upper heating element 2, a lower heating element 3, and a purifying device 12 described later. And a temperature detecting means 5 such as a thermistor.

Reference numeral 6 denotes a cooking menu setting means arranged on the front of the outer shell 13, 7 denotes a control means, and 8 denotes a tray, which comprises a saucer 9, a grill 15, a handle 10, and a door glass 11.

Reference numeral 12 denotes a purifying device, which integrally combines an oxidation reaction promoting catalyst 12a made of a noble metal such as platinum or palladium with an adsorbent catalyst 12b such as activated alumina, zeolite or ceramic which can be used even in a high-temperature atmosphere. It is arranged on the cooking cabinet 1 side in an exhaust passage 17 extending from the cooking cabinet 1 to an exhaust port 14 opened on the back of the outer shell 13.

As shown in FIG. 3, the oxidation reaction promoting catalyst 12a and the adsorbing catalyst 12b are separately provided, and the adsorbing catalyst 12b is provided behind the oxidation reaction promoting catalyst 12a. Although not shown, it may be provided in the front.

An exhaust fan 16 is installed between the purifier 12 and the exhaust port 14 and forcibly exhausts smoke from the cooking cabinet 1 to the outside.

FIG. 4 shows an operation section of the cooking menu setting means 6, which includes a display section 6a and automatic cooking sections 6b, 6c, 6c.
d, 6e, 6f, 6g, 6h, 6i, deodorizing 6j, manual cooking section 6k, start switch 6m, and cancel switch 6n.

The automatic cooking units 6b to 6i are automatic menu switches for whole fish and the like, and can be set with a baking control switch 6p. Can be switched to three stages.

[0016] The manual cooking unit 6k is △ (up), ▽ (down)
n) a timer set switch 6q and a heater changeover switch 6r for switching between double-sided grilling and upper-fired grilling.

Next, the operation of one embodiment of the present invention will be described.

First, a grill 15 is placed on the tray 8, fish and other ingredients are placed thereon and inserted into the cooking cabinet 1, and then
Press any switch from the automatic cooking units 6b to 6j of the cooking menu setting means 6, and set the baking control switch 6p as desired.
Press to select strong / medium / weak.

Subsequently, when the start switch 6m is pressed, cooking is started.

When cooking is started, the display section 6a changes to a display state indicating that automatic cooking is being performed. First, the catalytic heater 4 and the exhaust fan 16 are energized, and the catalytic heater 4 heats the purifying device 12 in advance to quickly exhibit the purifying function. The temperature is reached, and the temperature detected by the temperature detecting means 5 (usually substantially equal to room temperature) is stored as an initial temperature in the microcomputer of the control means 7.

Subsequently, the lower heating element 3 is energized to generate heat,
The temperature inside the cooking cabinet 1 is raised, and foods such as fish are heated, so that the back surface is moderately browned.

Next, the energization of the lower heating element 3 is stopped, and the energization of the upper heating element 2 is performed, so that the surface of food such as fish is scorched.

Thereafter, the energization of the upper heating element 2 is stopped,
The lower heating element 3 is energized again to bake the gravy and oil attached to the back surface of foods such as fish to improve the finish.

Finally, when the remaining time display on the display section 6a becomes 0, the power supply to the lower heating element 3 is stopped, and a buzzer (not shown) sounds to notify the user of the end of cooking.

In the above operation, since the purifying device 12 is heated in advance by the catalytic heater 4 and the temperature in the cooking chamber 1 is stabilized, the purifying device 12 has reached the purifying function exhibiting temperature. Most of the dirt (juice and fat) of the heated object attached to the upper heating element 2 and the lower heating element 3 is converted into colorless and odorless carbon dioxide and water vapor, and is discharged from the exhaust port 14 through the exhaust passage 17 and the user. Does not cause discomfort.

Next, when cooking a menu with fermented products such as miso and soy sauce, or a heated menu of 6 g of toast (bread), the cooking itself is the same as described above, but the purification device 12 is heated to a sufficiently high temperature. If not, the oxidation reaction accelerating catalyst 12a does not reach the temperature at which the purification function is exhibited, so that the alcohols generated from the foodstuffs cause an incomplete oxidation reaction,
Generates an irritating odor (acetaldehyde, etc.).

However, in the present invention, the irritating odor is combined with the oxidation-promoting catalyst 12a and the adsorbing catalyst 12b or the adsorbing catalyst provided before or after the oxidation-promoting catalyst 12a. The gas is held once by 12b to purify gradually, and after a complete oxidation reaction is performed, the gas is discharged from the exhaust port 14 to the outside.

Therefore, no irritating odor is generated, and no discomfort is given to the user.

[0029]

As described above, according to the present invention, a large amount of alcohol or the like is generated when heated with a fermented product (miso, soy sauce), bread or the like, and completely purified with an air purification catalyst. In a process that cannot produce an irritating odor (acetaldehyde, etc.) due to an incomplete oxidation reaction due to a colorless and odorless carbon dioxide and water vapor that cannot be oxidized, an adsorptive catalyst that is combined with an oxidation reaction promoting catalyst, or By holding the catalyst with an adsorbent provided before or after the oxidation reaction promoting catalyst and purifying it gradually, exhausting it through the exhaust port after complete oxidation reaction, discomforting the user Fish roasters that do not feed can be provided.
