Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smokeless roaster installed in a barbecue shop or the like, in which a fireproof damper is made detachable and early detection of the accumulation of oils and fats by an inspection rod. When,
The present invention relates to an attachment / detachment device for a fireproof damper for a smokeless roaster, which comprises an oil / fat separating plate for removing an oil / fat component and can maintain smooth operation of the fireproof damper. 2. Description of the Related Art FIG. 1 shows an average structure of a smokeless roaster 1.
Is shown schematically in FIG. The meat pieces 3 placed on the grill 2 are burned by the burner 5, and the generated smoke 6 is exhausted by a suction force of an exhaust fan (not shown) so as to surround the ring 7. Head to passage 12a. Further, a part of the roasted meat pieces 3 and the meat juice 4 and the like are separated into the water tank 8 installed below the grill 2 and land on the water 37 stretched in the water tank 8. Although the generated smoke 6 partially includes the oil component 10 and the combustible residue 16, the oil 6 in the oil receiver 9 installed in the exhaust passage 12 a
The generated smoke 6 rotates toward the exhaust passage 12b while rotating.
At that time, a large amount of the oil component 10 and a part of the combustible residue 16 accumulate in the oil sump of the oil sump 9. Almost, the purified smoke 6 goes to the exhaust passage 12c while orbiting the exhaust passage 12b. Here, the exhaust passage 12d and the exhaust passage 12e are interposed with the ceramic grease filter 11 as the final stage.
After passing through, the purified smoke 6 generally passes through facilities such as a facility exhaust collecting pipe (not shown) and passes through facilities such as exhaust ducts 21a and 21b as means for joining the exhaust pipes. It is a simple structure and is the trend of generated smoke. The ceramic grease filter 11, which has a final purifying function, is effective in locking the oil component 10 if the fineness is reduced. However, clogging frequently occurs, the exhaust resistance increases, and the exhaust passage 12d and the exhaust passage This is caused by the temperature rise of 12e. Therefore, the ceramic grease filter 1
The first point is that it is not possible to be very detailed. For the purpose of preventing a fire due to a rise in temperature, a fire damper 13 is provided between the exhaust passages 12d and 12e.
Usually installed. The valve 14 of the fire damper 13 is
3 and is temporarily fixed in the vertical direction by inserting a thermal fuse 15 and maintaining the function of easily discharging the generated smoke 6 to the exhaust passage 12e. Further, when the smokeless roaster 1 is installed in a barbecue shop or the like, the valve 14 of the fire protection damper 13 is manually operated in order to keep the exhaust suction power of the fire damper 13 installed in a uniform manner. They may be temporarily fixed and tentatively fixed. When an abnormal temperature rise occurs due to the ignition of the oil component 10 or the combustible residue 16, the temperature of the exhaust gas rises, and hot air propagates to the exhaust passages 12b, 12c, 12d, and 12e. Thermal fuse 15 inserted in fire damper 13
However, when the high temperature is sensed, the temperature fuse 15 is melted and cut, and the valve 14 pivotally attached to the fire protection damper 13 is pivoted about the pivot 33 by the mechanism of the spring 17 (FIG. 2), so that the horizontal position is reached. To shut off the exhaust passage 12e and shut off air and hot air. That is, the fire prevention damper 13 has a function of preventing an early fire. As described above, the fire damper 13 is indispensable to prevent the smokeless roaster 1 from being fired at an early stage, and sufficient care must be taken to maintain its function. . Therefore, if the inspection of the ceramic grease filter 11 is neglected, the oil 10 mixed with impurities becomes a semi-solidified jelly-like oil reservoir 22 (FIG. 4), and the exhaust passage 12d,
The exhaust passage 12e, the valve 14 of the fire damper 13, the thermal fuse 15, and the like are formed. Further, since the ceramic grease filter 11 is also clogged, the exhaust resistance increases, and the temperature around the ceramic grease filter 11 and the exhaust passage 12d increases. Therefore, if the inspection of the ceramic grease filter 11 is neglected, an abnormal temperature rise occurs not from the main body of the smokeless roaster 1 in which the meat pieces 3 are burned by the burner 5 but from the vicinity of the place where the oil sump is difficult to clean, and The temperature fuse 15 to which the semi-solidified jelly-like oil reservoir 22 is fixed and the valve 14 of the fire protection damper 13
Therefore, the function of the smokeless roaster 1 for preventing an early fire is remarkably impaired because the original function is poorly exhibited. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and its gist is to attach and detach a fireproof damper installed in an exhaust passage of a smokeless roaster.
