Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a smoke purification type cooker, such as a lo-su, which disposes of smoke generated during grilling or the like.

<Prior Art> Some conventional cooking appliances discharge inhaled smoke to the outside through a duct, but in this case, the duct has the disadvantage that it is troublesome to install and cannot be moved.

<Purpose> Therefore, the present invention does not require a smoke exhaust duct,
To provide a smoke purification type cooker which can be used in exactly the same way as a normal cooker and can quickly dry an electrode part of a dust collection part of an electrostatic precipitator to which water droplets have adhered during cleaning etc. for reuse.

<Example> Hereinafter, an example of the present invention will be described with reference to the drawings. The smoke purification cooker of this example has a rectangular roaster 2 (including a wire mesh etc. ), pipe gas burners 3 are provided on the lower side thereof, and an outer case 4 is provided outside the inner case 1 so that the inner case 1 and the outer case 4 form a smoke suction path 4A, and The smoke suction port C5 of the smoke suction passage 4A is arranged on the upper side of the outer periphery on the long side of the rostol 2, and
A coarse oil smoke rectifier 5 and an electrostatic precipitator 6 are installed at the bottom of the
is provided, a white-shaped electric fan 7 is provided below the electrostatic precipitator 6, a top support box 8 is provided to surround the outer case 4, and the box 8 and the outer case 4 are connected to each other. An exhaust passage 9 is formed between the two, and the outlet of the fan 7 is connected to the entrance of the exhaust passage 9.
Exhaust passage outlets 1 are provided at the upper and lower sides of the short sides of the box 8, which is rectangular in plan view, apart from the combustion gas inlet C5.
0 is formed, and purified air is passed through the exhaust path 9 by the blowing pressure of the electric fan 7, and the purified air is blown out from the side of the box 8.

Note that the upper end of the support box 8 supports the top plate A.

11 is a combustion part frame integrated with the combustion gas inlet C5, 12 is a gas intake that penetrates a part of the box 8 and is connected to the gas pipe, and 13 is arranged on the top plate on the side of the rostre 2. 14 is an electric switch for turning on and off the electric dust collector 6 and the electric circuit of the combustion section.

The rectifier 5 has a function of causing relatively large particles of oil smoke to adhere to its wall surface, and the dust collector 6 generates corona discharge from its positive electrode to remove relatively small oil particles and smoke particles. It has a processing function. Reference numeral 16 denotes a filter replacement door for the rectifier 5 and the dust collector 6, which is provided so as to be openable and closable.The lower part of the door is rotatably supported on the support box 8 via a hinge, and the upper part is provided with a plate spring on the side of the support box 8. Knob 1 that engages with 17
8, and an activated carbon or other deodorizing filter 16a is removably attached to its inner surface. 19 is a dust collection electrode for charging smoke particles. 20 is a dust collection lid provided on the outer case 4 so as to be openable and closable. P is the oil pan.

Next, the electric circuit shown in FIG. 5 will be explained. In the present invention, the electric fan 7 is operated only when the dust collecting part 6a of the electrostatic precipitator 6 is set in the normal position.
The first switch LS1 turns on the motor 7M and turns on the high voltage generating circuit 6b of the dust collecting part 6a only when the dust collecting part 6a is drying at high speed (in this embodiment, when the dust collecting lid 20 is open).
A second switch LS2 is provided to turn OFF, and the first switch LS1 is ON and the second switch LS2 is turned OFF.
A combustion part electric circuit B is provided which can cause the burner 3 to burn even in the OFF state.

In other words, first switch LS1 and electric fan 7
is connected in series with the motor 7M, and the second switch
High voltage (6KV) generation circuit 6 for LS2 and dust collection section 6a
The series connection circuit with b and the motor 7M of the electric fan 7 are connected in parallel, and as shown in FIG. The first switch LS1 is turned on only when the lid is closed and engaged with the dust collector 6c, and the first switch LS1 is turned on only when the dust collecting part 6a is pushed into the normal position. IDD also switches relay CR when high voltage generation circuit 6b is short-circuited.
This is a safety circuit that turns CR1 and CR2 OFF.

Next, to explain the operation, the smoke (oil mist, oil smoke) generated from the food on the roaster 2 is mixed with the indoor air (E in Figure 3) through the combustion gas inlet C5 and sucked in at a relatively low temperature. The air enters the rectifier 5 and electrostatic precipitator 6 through the smoke suction path 4A, where it is purified and becomes purified air, which reaches the exhaust path 9 to the upper and lower outlets 10 of the support box 8, and is discharged to the outside. Ru.

All the energy of the airflow at this time is given from the fan 7. In addition, the smoke inlet C5 and the exhaust path 9
It is spaced apart from the outlet 10 of the exhaust path 9, and the outlet 1 of the exhaust path 9
The smoke generated from the food on the roaster 2 will not rise due to the rising warm air coming out from zero. Then, the rectifier 5 causes the mist with large particle size to adhere to its wall surface, and the dust collector 6 causes the smoke with small particle size to be sucked into the dust collecting section 6a, and passes through a positive corona discharge to collect the smoke by ozone. The particles are charged and the dust collection electrode 19
Attach to. Note that the thinner the positive discharge electrode is, the more efficient it is and the less ozone is generated. Although oil mist can be completely collected, if the deodorizing effect of ozone is not sufficient, use a deodorizer such as Anico (a product developed by the Agency of Industrial Science and Technology) or Deozo Lighter (a product of Morishita Jintan Co., Ltd.) on the door 16. Even more complete deodorization can be achieved by providing it on the back side.

Since oil smoke and smoke particles adhere to the rectifier 5 and the dust collecting section 6a, it is necessary to periodically clean or replace them, but this can be easily done by opening the door 16.

Note that when cleaning the dust collecting section 6a,
If it gets wet with spilled beer, etc., and you want to quickly dry it and reuse it, follow the steps below.

First, the door 16 is left open, the dust collecting part 6a is set in the normal position, the first switch LS1 is turned ON, and the engaging piece 20a of the dust collecting lid 20 is inserted into the hole 6a.
The second switch LS2 is in the open state when removed from c.
OFF state (high voltage generation circuit 6b is OFF)
So, since combustion part electric circuit B is ON, burner 3
is ignited to cause hot air to pass through the dust collecting section 6a, thereby rapidly drying the dust collecting section 6a.

Furthermore, in the present invention, the outlet 10 of the support box 8 is designed to prevent hot air from hitting the user when the user sits on both long sides of the top plate.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

<Effects> As is clear from the above explanation, the present invention has an inner case arranged in the center hole of the top plate, a cooking plate such as a roaster on the upper part of the inner case, and a burner on the lower side thereof. An outer case is fitted between the inner case and the electric fan to form a smoke suction path, and an electrostatic precipitator is installed in the smoke suction path. An exhaust path communicating with the outlet is formed, and the first switch turns on the motor of the electric fan only when the dust collection part of the electrostatic precipitator is set in the correct position, and the dust collection part is turned on only when the dust collection part is dried at high speed. A second switch for turning off the high voltage generating circuit of the burner is provided, and a combustion section electric circuit is provided that allows the burner to burn even when the first switch is on and the second switch is off. This invention relates to a smoke purification type cooker.

Therefore, according to the present invention, there is no need for a smoke exhaust duct, and the warm air from which the smoke has been purified is distributed to the outer part of the cooking plate such as a roostle, which is separated from the outer periphery of the cooking plate, and which is separated from the smoke suction part by the top plate support. Since the air is blown out from the box to the side, the user can use it just like a regular cooker, and the smoke generated from the food on the cooking plate is removed together with the rising warm air coming out of the outlet of the exhaust duct. It rarely rises. Furthermore, the functions of the first and second switches allow it to be used in exactly the same way as a regular cooker, and can quickly dry the electrode part of the dust collecting part of the electrostatic precipitator that has water droplets attached to it during cleaning, etc. for reuse. It has excellent effects.
