The rectifying box 19 has slits 22 at predetermined intervals so as to overlap the upper end opening 21 of the rectifying box 19, which is set to have a larger diameter than the diameter of the rectifying box 1.
A drain box 23 is attached to the bottom of the drain box 9 so that it can be pulled out freely.

24 and 24a are electrostatic precipitator units installed and arranged in series in the flow path 25 of the ventilation pipe 18;
The electrostatic precipitator units 24, 24a have a large number of ventilation holes 27, 27a penetrated through a rectangular base 26.
. . . and discharge electrodes 28, 28a disposed at the center of the vent holes 27, 27a.
By applying a predetermined voltage to the dust collecting electrodes 29, 29a on the inner surface, a discharge is caused between them, and particles such as smoke passing through the ventilation holes 27, 27a are charged and collected. Electrodes 29, 29a...
It is designed so that it can be removed by adsorption.

Further, the electrostatic precipitator units 24 and 24a are connected to the ventilation pipe 1.
A guide member 30 fixed to the top and bottom of the inner surface of 8,
30a, 31, 31a so as to be freely drawn out, and the ventilation holes 27, 27a... are supported in a state inclined with respect to the horizontal axis direction, while a drain receiver 32 is disposed at the bottom of the ventilation pipe 18 so as to be freely drawn out.

It is connected to.

Note that 41 is an exhaust pipe that is fitted and attached to the exhaust port 40.

Next, to explain the function of the smoke eliminating device for a roaster according to the present invention, exhaust gas such as smoke and oil particles that rises as the food is baked on the roaster 10 is removed from the upper sides of the roaster 10 by the suction action of the fan 37. It is sucked into the suction channel 7 between the inner box 8 and the outer box 6 from the suction holes 13, 13a...
Further, through the smoke exhaust pipe 15, the smoke exhaust port 16 reaches a rectifier box 19 disposed below, and in the rectifier box 19, components with large particle sizes fall under their own weight into the drain box 23 at the bottom or are removed from the rectifier box. 19 and the ventilation pipe 18 and fall and are removed.

Further, in the process of sucking the exhaust gas into the rectifier box 19 from the smoke exhaust port 16, outside air is mixed in through the slit 22, and the temperature of the exhaust gas is lowered by the mixing of the outside air.

Next, in the process of sucking the exhaust gas from the rectifier box 19 into the vent pipe 18, the exhaust gas is rectified in the rectifier box 19 and the filter 34, so that the ventilation density with respect to the opening area of the vent pipe 18 is made uniform, and the exhaust gas is drawn into the vent pipe 18. relatively large particle components in the exhaust gas are removed.

Then, the exhaust gas containing fine particles such as burning smoke and oil first reaches the electrostatic precipitator unit 24 in the previous stage, and then passes through the ventilation hole 2.
In the process of passing through the air holes 27, 27a..., the fine particles are charged to a negative charge by the discharging action of the central discharge electrodes 28, 28a, and at the same time they are charged, the air holes 27, 27a..., which are on the positive side, The fine particles that are adsorbed and removed by the dust collecting electrodes 29, 29a... and accumulated on the dust collecting electrodes 29, 29a... sequentially flow in the direction of inclination of the electrostatic precipitator unit 24 and flow through the outflow holes 33, 33a... to the bottom. drain receiver 3
2, and then the electrostatic precipitator unit 2.
The exhaust gas that has passed through 4 is sent to the subsequent electrostatic precipitator unit 2.
In the process of passing through the exhaust gas 4a, fine particle components are similarly removed by electrostatic precipitation, and furthermore, in the process of passing through the deodorizing unit 35 disposed downstream of the electrostatic precipitators 24 and 24a in the vent pipe 18, activated carbon is removed. The air is deodorized by the gas, and is scented with an aromatic agent, which is then sucked into the subsequent exhaust section 5.

Next, the exhaust gas passes through the fan 37 to the ventilation pipe 18.
The gas flows from the gas into the muffling box 39, where the blowing sound from the fan 37 is muffled and is directly exhausted into the room through the exhaust port 40 as clean gas.

In addition, when cleaning oil etc. removed from exhaust gas, drain box 23 and electrostatic precipitator unit 2 are used.
4, 24a, the drain receiver 32, the filter 34, and the deodorizing unit 35 can be removed by pulling out each part, so cleaning can be easily performed by removing these parts.

In short, the present invention has a rectifying box 19 equipped with a drain box 23 at the bottom directly below the smoke exhaust port 16 connected to the combustion section 3 of the roaster body 1, so that the exhaust gas sucked through the smoke exhaust port 16 can be removed. By being diffused in the rectifying box 19 at one end, the flow can be rectified, and the coarse particle components in the exhaust gas can be collected and removed into the drain box 23 at the bottom by falling under their own weight.
In addition, since slits 22 are provided at a predetermined interval in the joint 20 between the rectifier box 19 and the smoke exhaust port 16, the outside air is removed from the slits 22 before the gas is sucked into the subsequent smoking section 4 and exhaust section 5. The temperature of the high-temperature exhaust gas containing combustion gas can be lowered by the mixing of
This reduces the heating burden on the fan 37 and improves the durability of these devices, and also reduces the temperature of the exhaust gas that is directly exhausted into the room from the roaster body 1. In addition, a suction fan 3 is installed on the side of the rectifier box 19.
7 is attached to the ventilation pipe 18, and an electrostatic precipitator unit 2 is connected to the flow path 25 of the ventilation pipe 18.
4, 24a, and the electrostatic precipitator unit 24,
Numerous ventilation holes 27 24a are provided through the base 26,
27a... and discharge electrodes 28, 28a... disposed at the center of the vent holes 27, 27a...;
27a... Since the dust collecting electrodes 29, 29a... on the inner surface are caused to discharge between them and the particles are adsorbed and removed by the dust collecting electrodes 29, 29a..., the exhaust gas sucked into the ventilation pipe 18 contains The dust collecting electrodes 29, 29a... by charging action remove harmful components such as burning smoke and oil particles.
The electrostatic precipitator units 24, 24a are supported in such a manner that the exhaust gas vents 27, 27a are inclined with respect to the horizontal axis direction, and the electrostatic precipitator units 24, 24a are supported in such a manner that the exhaust gas vents 27, 27a... are inclined with respect to the horizontal axis direction. Since the drain receiver 32 is disposed at the bottom of the vent pipe 18 facing below the units 24, 24a, the drain such as oil that has been adsorbed and removed by the electrostatic precipitators 24, 24a can be collected by the electrostatic precipitators 24, 24a. The inclination allows the dust to drip out in sequence and be collected and removed into the drain receiver 32 at the bottom, and thus the dust collection electrodes 29, 29a of the electrostatic dust collection units 24, 24a...
The accumulation of condensate such as oil on... is prevented, and the dust removal efficiency by the electrostatic precipitator units 24, 24a can always be maintained at the best condition, and the air outlet 38 of the fan 37 is opened at an appropriate location in the roaster body 1 to exhaust air. Since the exhaust gas is connected to the port 40, the exhaust gas from which harmful components have been removed by the electrostatic precipitator units 24 and 24a can be exhausted indoors as clean gas. Since the process can be performed using only the mechanism, it is possible to reduce equipment costs without requiring separate duct piping under the floor unlike the conventional centralized duct system, and the location of the roaster body 1 is not limited and can be relocated. Also, the exhaust gas is returned indoors as clean gas, reducing the heating and cooling load.

In addition, a drain box 23, an electrostatic precipitator unit 2
4, 24a, and the drain receiver 32 are attached so that they can be freely pulled out, so that the practical effects include that drains such as oil removed from exhaust gas can be easily cleaned by simply pulling out and operating these members. It's huge.
