[0007]

In the smokeless roaster described above, meat and the like are placed on a grill 54, and the meat and the like are grilled by direct fire from a gas burner 55. Therefore, depending on the cooking time, the meat may be over-burnt and burn or become hard. The juice from the meat falls directly into the gas burner 55 from the gap in the grill 54. For this reason, the flame opening of the gas burner 55 is clogged, or the gas burner 5
5 is corroded with time and shortens its life. Further, the heat of the gas burner 55 causes the water in the water tank 57 to boil immediately (for example, 5 to 10 minutes) and evaporate, and the temperature of the equipment becomes high, increasing the risk of a duct fire or the like. Therefore, water must be supplied to the water tank 57 frequently.

The present invention has been made in view of the above problems, and has as its object to provide a cooker that can bake a food to be cooked gently and that is easy to use.

[0009]

A plurality of minute holes are formed on the surface of the heat permeable plate so as to prevent a falling object from the object to be cooked from reaching the heating unit.

According to this configuration, the heating net is heated by the heating unit and emits far-infrared rays, and the far-infrared rays pass through the holes of the heat-transmissive plate and supply radiant heat to the cooking unit.
Due to this radiant heat, the food placed on the cooking section is heated to the inside and is baked mellowly like charcoal grill. At this time, meat juice, meat pieces, and the like from the object to be cooked are blocked by the heat permeable portion, and do not enter the heating portion or the like located below.

Further, if a water tank is provided around the heating section and a support plate is provided between the water tank and the heating net, far infrared rays from the heating net are reflected upward. This allows the support plate to reflect the radiant heat from the heating net and prevent heat conduction to the water tank, thereby suppressing evaporation of water in the water tank.

The heat permeable plate 12 is made of stainless steel and is formed in a bowl shape curved from the center to the periphery, with the periphery falling. A plurality of circular holes 15 are formed on the surface. This circular hole 15 has a diameter of φ3 to 5 mm, preferably φ4.5.
mm, which is slightly smaller than the water drop of the gravy. Therefore, the gravy that falls from above is less likely to enter the circular hole 15 and flows down along the bowl-shaped surface. Therefore, since meat juice and the like do not directly fall on the gas burner 6 immediately below the heat permeable plate 12, the flame opening of the gas burner 6 is not clogged, and a stable flame is formed. Further, corrosion of the gas burner 6 can be prevented.

The heat generating net 13 is made of a stainless steel net and has a bowl shape slightly smaller in diameter than the heat permeable plate 12. The heat generating net 13 is heated to a deep red by the radiant heat from the gas burner 6, radiates far infrared rays, and supplies radiant heat to the food. With this far infrared ray, the grid 5
Meat can be baked softly and mellowly to the core.

The support plate 14 is a stainless steel dish, has a diameter smaller than that of the heat permeable plate 12 and is larger than that of the heat generating net 13, and a peripheral edge of the opening 16 serves as a flange and is locked on the peripheral wall 10 of the water tank 9. You. The heat generating net 13 is placed on the upper surface of the support plate 14, and the heat permeable plate 12 is supported by being covered with a standing frame 17 formed on the outer periphery.

An intake plate 20 is provided so as to surround the periphery of the grill 5, and cooking gas is sucked from an intake port 21 formed in the intake plate 20. The intake plate 20 has a cylindrical shape whose upper part is bent outward, and is placed on the upper edge of the water tank 9.
The hood 22 is detachably attached to the upper edge of the decorative frame 3 with a gap so as to surround the upper part of the intake plate 20. By sucking outside cold air from the gap and the air inlet 21, the air curtain function has an air curtain function of preventing scattering of oil smoke and oil droplets and cooling cooking gas.

A communication port 23 formed on the bottom surface of the decorative frame 3 and an exhaust port of the dust collector 4 pass through a gap between the inner surface of the decorative frame 3 and the outer surface of the water tank 9 from the intake port 21. A suction passage 25 for leading to the suction passage 24 is formed. A duct 26 for discharging the purified cooking gas to the outside is connected to the exhaust port 24, and an inlet of the duct 26 prevents the high-temperature cooking gas from entering the duct 26 in an empty firing state. A fire damper 27 for blocking the exhaust port 24 is detachably mounted. When the temperature of the fire prevention damper 27 reaches a predetermined temperature (for example, 150 ° C.), the built-in temperature fuse 28 is blown, and the exhaust port 24 is closed.

The dust collecting section 4 is provided with a pre-filter 30 for preventing inflammable combustibles such as chopstick bags, paper and pieces to be cooked on the top plate 2 from entering, and a downstream side of the pre-filter 30. A grease filter 31 for collecting oily smoke, and an oil pan 3 for storing oil and fat collected by the grease filter 31

Is made of two stainless steel punching plates so that relatively large dust (combustible material such as meat pieces) does not pass through. The grease filter 31 is made of expanded metal made of stainless steel. In FIG. 2, reference numeral 33 denotes an operation unit provided with a power switch, an instrument stopper, and an indicator lamp, and reference numeral 34 denotes a maintenance door.

In such a configuration, the gas burner 6
When the cooking is started by placing raw meat, vegetables, and the like on the grill 5, the heating net 13 is heated to red. Thereby, the heating net 13 emits far infrared rays. Accordingly, the heat-transmissive plate 12 is also heated red and emits far-infrared rays.
The raw meat is supplied with radiant heat by far-infrared rays from the heat-transmissive plate 12 and is supplied with radiant heat by far-infrared rays from the heat generating net 13 through the circular holes 15 of the heat-transmissive plate 12. That is, the heating net 13 and the heat-transmissive plate 12 exhibit a far-infrared effect, and the raw meat is heated to the core by the supply of radiant heat like a charcoal grill, and is grilled plumply and mellowly without burning.

By the way, when meat is roasted, gravy is formed,
It falls from the gap of the grill 5. Since the heat permeable plate 12 is disposed below the grill 5, the gravy falls onto the heat permeable plate 12, but since the circular holes 15 of the heat permeable plate 12 are formed smaller than water droplets, Instead of passing through the circular hole 15, it travels along the surface, is gradually collected on the periphery, and falls from the periphery into the water tank 9. Further, at this time, since the heat permeable plate 12 is heated to approximately 300 ° C., the gravy is repelled on the surface of the heat permeable plate 12 and falls from the periphery of the heat permeable plate 12 or directly to the water tank 9.

As a result, meat juice, meat pieces and the like do not fall onto the gas burner 6 below the heat permeable plate 12, so that the flame opening of the gas burner 6 is clogged or the gas burner 6 is corroded. Can be suppressed. In addition, since meat juice and the like are not applied to the heat generating net 13 immediately below the heat permeable plate 12, the heat generating net 13 can exhibit the far-infrared effect well.

The support plate 14 is located so as to cover the upper part of the water tank 9. Therefore, radiant heat from the heat permeable plate 12 and the heat generating net 13 placed on the support plate 14
And does not reach the water tank 9. Therefore, evaporation of water in the water tank 9 can be suppressed, and there is no need to supply water frequently. Further, the radiant heat is reflected by the support plate 14, and the heat-transmissive plate 12 and the heat generating net 13 are quickly heated by the reflected heat, so that the heat efficiency is improved, and the start-up time until warming can be shortened. Can be shortened.

According to the above structure, the grill 5, the heat permeable plate 12, the heating net 13, the support plate 14, the water tank 9 and the gas burner 6 can be easily removed from the decorative frame 3. Then, it is cleaned or replaced with a new one, and is fitted again into the decorative frame 3 and mounted. Thereby, cleaning and replacement become easy, and maintainability can be improved.

The present invention is not limited to the above embodiment, and many modifications and changes can be made to the above embodiment within the scope of the present invention. For example, the structure provided with the above-mentioned three-piece set may be applied not only to a gas-type smokeless cooker but also to any electric-type cooker.

[0029]

As described above, according to the present invention, the heating net is heated by the heating unit and supplies radiant heat utilizing far-infrared rays to the cooking unit. The cooked food is baked mellowly. Therefore, even if the heating unit is, for example, a gas burner, it is possible to provide a cooker that can cook meat or the like as an object to be cooked to the core as far as the charcoal-grilling by far-infrared rays.

Further, by using a heat permeable plate having a plurality of minute holes formed on the surface, far infrared rays from the heat generating net can be transmitted, but falling objects from the cooking section can be blocked. Compatible protection of internal equipment. Therefore, the life of the equipment such as the heating unit can be extended, and the reliability of the cooker can be improved.

Further, since the support plate reflects the radiant heat from the heat generating net and prevents conduction to the water tank, evaporation of the water in the water tank can be suppressed, so that it is not necessary to frequently supply water. It can be a good cooker.
