Abstract

PROBLEM TO BE SOLVED: To provide a smokeless roaster which has a constitution in which meat juice does not stay on the bottom end part of a charcoal pot and can stably hold a fire grating. SOLUTION: As a charcoal pot 14 is formed into a cylindrical shape becoming narrower from the top end opening 15 to the bottom end opening 16, there exists no possibility of collecting and firing of meat juice in the bottom end opening. Posture stabilizing arms 18h obliquely upward projecting from the outer periphery of a large diameter ring-like mount member 18d at approximately 120 degree intervals and positioning legs 18i which are not projected from the outer periphery of the large diameter ring-like mount member 19d and are bent at approximately 120 degree intervals downward at approximately right angles are formed on the fire grating 18 and when the fire grating 18 is fitted in the bottom end opening of the charcoal pot 14, it is held by an approximately horizontal stabilized posture by bringing the posture stabilizing arms 18h into contact with three positions of the inner peripheral face of the cylindrical part 14b and as the positioning legs 18i are positioned so as to be able to bring them into contact with three positions of the inner peripheral face of the straight cylindrical part 14, the fire grating is positioned approximately at the center of the bottom end opening 16.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a sectional view of a smokeless roaster 1 according to the present embodiment. At the approximate center of the top plate 3 of the table 2, a circular cooking opening 4 is formed, and a table frame 5 that surrounds the cooking opening 4 is fitted. Outer pot 6
The upper end opening is inserted between the cooking opening 4 and the lower end of the table frame 5 and is fitted to the cooking opening 4. A top ring 7 is fitted on the inner periphery of the table frame 5.
A number of suction ports 8 are formed on the inner peripheral surface of the top ring 7.

A water tank 9 fitted inside the top ring 7 is mounted on a ring-shaped filter unit 11 arranged on the outer periphery of a smoke outlet 10 formed at the center of the bottom of the outer pot 6. Table frame 5 and outer hook 6, Table frame 5
The top ring 7 and the top ring 7 and the water tank 9 are kept substantially airtight, and the outer pot 6 and the water tank 9 define a smoke exhaust passage 12 in which the suction port 8 and the smoke exhaust port 10 communicate with each other. The filter unit 11 captures and removes oil particles in the flue gas by the filled grease filter 11a.

A supporting step 13 is formed at the upper end of the water tank 9, and a charcoal crucible 14 is placed and supported on the supporting step 13. As shown in FIG. 2, the charcoal crucible 14 has a substantially cylindrical shape having an upper end opening 15 and a lower end opening 16.
Is formed with a flange 15a, and the supporting step 13
To be placed on the Between the upper end opening 15 and the lower end opening 16, a curved cylindrical portion 14 a that becomes thinner at a constant curvature toward the lower end, a straight cylindrical portion 14 b continuous with the curved cylindrical portion 14 a, and a lower end opening from the straight cylindrical portion 14 b. A diameter-increased cylindrical portion 14c that increases in diameter toward 16 is formed. A grill 17 is placed on the flange 15 a of the upper end opening 15, and a grate 18 is detachably held on the lower end opening 16.

As shown in FIGS. 3 to 5, the grate 18 is concentric with the small central disc 18a on six connecting rods 18b radially protruding from the small central disc 18a at substantially equal angular intervals. In addition, a ring-shaped mounting member 18d having an outer diameter substantially equal to the inner diameter of the straight cylindrical portion 14b and a ring-shaped mounting member 18e having a diameter smaller than that are welded, and a reinforcing connecting rod 18f is connected between the connecting rods 18b. A charcoal mounting surface 18g is formed by welding to the ring-shaped mounting members 18d and 18e. Connecting rod 18
b shows the posture-stabilizing arm 18h formed by bending the protruding end projecting from the outer periphery of the large-diameter ring-shaped mounting member 18d every other one obliquely upward, and the large-diameter ring-shaped mounting member. 1
8d, do not project from the outer periphery of
i is bent at a substantially right angle.

When the fire grate 18 is fitted to the lower end of the charcoal crucible 14, three posture-stabilizing arms 18h projecting obliquely upward from the outer periphery of the large-diameter ring-shaped mounting member 18d at intervals of about 120 degrees. Are abutted at three places on the inner peripheral surface of the curved cylindrical portion 14a and are held in a substantially horizontal stable posture. Further, three positioning legs 18i bent downward at substantially right angles at intervals of approximately 120 degrees without projecting from the outer periphery of the large-diameter ring-shaped mounting member 18d are provided on the inner peripheral surface of the right cylindrical portion 14b. The grate 18 is positioned substantially at the center of the lower end opening 16 so as to be able to abut on the location.

On the side wall of the water tank 9, a blast air supply port 19 is formed corresponding to the lower side of the charcoal crucible 14. A blower fan 20 is attached to the outer hook 6 so as to correspond to the feed port 19. The air supply port 19 and the air supply port 21 of the air supply fan 20 are connected by an air supply pipe 22.

Further, an exhaust duct 25 is connected to the smoke outlet 10 of the outer kettle 6 for exhausting smoke and exhaust gas sucked from the suction port 8 to the outside of the room. The exhaust duct 25
A temperature fuse 26 and a displacement adjusting damper 27 are arranged. The thermal fuse 26 is connected to the grease filter 11a.
The oil particles adhering to the air ignite, etc.
When the internal temperature rises, it is blown and the displacement adjustment damper 27
Is closed by the urging force of an unillustrated spring, and the flame
To prevent it from being sucked into.

The charcoal pot 14 of the smokeless roaster 1 having the above configuration.
Is formed between the upper end opening 15 and the lower end opening 16 by a curved cylindrical portion 14a that becomes thinner at a constant curvature toward the lower end, a straight cylindrical portion 14b continuous with the curved cylindrical portion 14a, and a straight cylindrical portion 14b. Since the enlarged diameter cylindrical portion 14c that expands toward the lower end opening 16 is formed and the fire grate 18 is fitted and held in the lower end opening, meat juices and the like fall into the lower end opening 16 and the water tank 9, It does not accumulate in the lower end opening and burn up.

On the grate 18, there are three posture-stabilizing arms 18h projecting obliquely upward from the outer periphery of the large-diameter ring-shaped mounting member 18d at intervals of about 120 degrees, and a large-diameter ring-shaped mounting member. Three positioning legs 18i which are bent downward at substantially right angles at intervals of approximately 120 degrees without being projected from the outer periphery of the member 18d are formed. Therefore, when the grate 18 is fitted into the lower end opening of the charcoal crucible 14, the posture stabilizing arms 18h abut at three locations on the inner peripheral surface of the curved cylindrical portion 14a, and the grate 1
8 is held in a substantially horizontal stable posture, and the positioning legs 18i are located at three positions on the inner peripheral surface of the straight cylindrical portion 14b so that the grate 18 is positioned substantially at the center of the lower end opening 16. You.
