Description

[Detailed description of the invention] (Industrial application field) This invention eliminates indoor air pollution and environmental pollution by cleaning soot containing oil generated from a yakiniku pot when grilling fish, meat, etc. This invention relates to a Yakiniku pot for home or commercial use that has an improved cleaning function to prevent this.

(Problems to be solved by conventional technology and ideas) When grilling fish, meat, etc. is placed on a stove or gas burner and grilled fish or meat with the direct heat of the flame, oil droplets etc. melted due to the high heat. It burns while flowing out. As a result, soot containing oil decomposition gas and a severe odor contaminates the indoor air, stains indoor furniture and accessories, and causes unhygienic problems such as breathing problems.

Conventionally, in order to correct such problems, a hopper was installed above the gas range to guide soot and smoke, and it was connected to a smoke exhaust pipe installed outdoors, and an exhaust fan was used to remove the soot and smoke generated when grilling meat. Methods and devices have been put into practical use that suck in and forcibly discharge the waste to the outside. Note that this is the most basic configuration. However, in such a configuration, the exhaust equipment is fixedly installed indoors, which limits the use of indoor space and is not aesthetically pleasing. Furthermore, due to their lack of mobility, they were not used outside of specially fixed business locations.

In order to solve this problem, a yakiniku cooker equipped with a soot purification device was developed in the 1980s.
One example is the yakiniku ware disclosed in No. 16242. This Yakiniku machine has a burner and a combustion tube installed at the top of the main body, a water tank is formed at the bottom of the main body, and an exhaust fan guides the soot that rises when grilling meat to the water tank below. It is designed to exhaust smoke from above for cleaning.

This type of yakiniku cooker has a simpler structure than the conventional one with a smoke exhaust pipe fixedly installed outside.
It has the advantage of being able to be transported and moved at will. However, although it is possible to condense vaporized oil droplets to some extent by simply passing soot over water, it is not possible to completely remove odors and smoke, and in particular, it cannot remove fine particles such as carbon powder. The problem was that it was difficult to clean, and the soot and smoke purifying function could not be expected.

(Means for Solving the Problems) Therefore, the present invention corrects the above-mentioned deficiencies in soot and smoke cleaning in conventional yakiniku cookers, and eliminates the soot, odor, and vaporized soot that occur when grilling meat. It can cleanly purify even dust such as oil and carbon powder, and
Since the cleaning part and the microwave are integrated, it has a neat appearance and is easy to transport, while preventing contamination of the indoor air when grilling meat, making grilling fish and meat more hygienic and convenient. The purpose is to make it possible.

In the invention of the present application, in order to solve the above problems, a barbecue grill is constructed using the following configuration.

A circular combustion section equipped with a gas burner 2 and an air intake port 23 is installed in the center of the yakiniku machine body 1, which is a box. A large number of smoke exhaust holes 3'' are formed on the upper edge of the combustion tube 3' projecting upward so as to communicate with the inside of the yakiniku pot body 1, and around the combustion tube 3 inside the space of the yakiniku pot body 1. A soot and smoke guide plate 5 is formed in which a large number of smoke exhaust holes 4 are formed so that the holes gradually become larger as they go from the center to the left and right sides. An exhaust fan 9 and a sponge filter 1 are installed at the central exhaust port 7 of part B.
3 is installed, and in the space between the sponge filter 13 and the smoke exhaust port 19, soot and smoke is generated by sequentially combining a nonwoven fabric filter 14, an electrostatic dust collector 15, a carbon filter 16, an auxiliary exhaust fan 17, and an ozone generator 18. This is a yakiniku utensil that is cleaned.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is an overall perspective view showing an embodiment of the present invention.

A yakiniku pot main body 1, which is a box, is divided into a combustion section A and a clean section B. The combustion section A is located in the center of the yakiniku machine body 1, and is equipped with a conventional gas burner 2 and a circular combustion tube 3'. As clearly shown in FIG. 3, the gas burner 2 is disposed at the center of the combustion chamber 3 inside the combustion tube 3'.
The thermal power of the gas burner 2 is adjusted by a gas regulator 22 installed on one side of the front of the yakiniku pot body 1. A grill 2' is placed horizontally above the gas burner 2.

An air intake port 23 is formed on one side of the combustion tube 3' to allow air to flow in from the outside, and air necessary for combustion in the gas burner 2 and air for transporting soot are supplied to the combustion tube. 3' is supplied inside.
A plurality of smoke exhaust holes 3'' are formed in the upper peripheral edge of the combustion tube 3' and communicate with the inside of the space of the yakiniku machine body 1.The air flowing into the air intake port 23 is ′, passes through the smoke exhaust hole 3″ along with the soot generated when grilling meat, and once enters the yakiniku pot body 1.
flows into the space inside.

As shown in FIG. 3, on one side of the periphery of the combustion tube 3' inside the space of the Yakiniku pot body 1, there is a soot guide plate 5.
is provided. This soot guide plate 5 is provided with a large number of smoke exhaust holes 4 formed such that the diameter thereof increases from the central portion toward the left and right sides. As a result, air containing soot and smoke that has flowed into the space of the yakiniku machine body 1 through the smoke exhaust hole 3'' on the upper end side of the combustion tube 3' passes through the exhaust port 7 to the clean area partitioned by the partition plate 6. It is discharged into the clean room B. This discharge is performed by the exhaust fan 9.

FIG. 2 shows the structure of the cleaning section B. Yakiniku pot body 1
The clean section B, which occupies one side of the tank, is partitioned by a partition plate 6, and is equipped with a small exhaust fan 9 driven by a motor 8, which inhales soot through an exhaust port 7. A sponge filter 13 is installed around the outlet of the exhaust fan 9 in a "U" shape.

A nonwoven fabric filter 14, an electrostatic dust collector 15, and a carbon filter 16 are arranged in this order between one side of the sponge filter 13 and a smoke exhaust port 19 at the rear of the yakiniku machine body 1. The nonwoven fabric filter 14 has a nonwoven fabric inside an aluminum mesh. The electrostatic dust collector 15 has a predetermined charging function and dust collection function due to a normal high-voltage discharge circuit device 12 placed on one side of the clean section of the yakiniku machine body 1, and the dust in the soot and smoke is removed. It is adsorbed to the electrostatic dust collector 15. Further, on the side of the electrostatic dust collector 15, a carbon filter 16 filled with activated carbon particles and a small auxiliary exhaust fan 1 are provided.
7. Ozone generators 18 are sequentially arranged. Odors and the like after dust collection are adsorbed and removed by the carbon filter 16, and harmful carbon monoxide and nitrogen gases are distributed into ozone and can be purified into harmless gases.

Further, in the figure, 10 and 11 are electric switches, 20 is a fuse, and 21 is a holder for mounting each filter.

Next, the operation of this embodiment will be explained.

According to such a configuration, fish and meat placed on the grill 2' are grilled by the heat of the gas burner 2 adjusted by the gas adjustment port 22, but at that time,
When the power switches 10 and 11 are turned "ON", the exhaust fans 9 and 17 are driven. At the same time, the electrostatic dust collector 15, nonwoven filter 14, etc. also come to perform their predetermined functions. Further, the ozone generator 18 also starts a predetermined action. The generated soot and smoke flow into the space of the yakiniku pot body 1 through the smoke exhaust hole 3'' formed on the upper peripheral surface of the combustion tube 3' together with the air sucked in from the air intake port 23.Inhalation of this soot is based on the operation of the exhaust fan 9. Then, the soot and smoke sucked into the space of the yakiniku machine body 1 passes through the large and small smoke exhaust holes 4 of the guide plate 5 to the clean area B divided by the partition plate 6. The smoke flows in through the exhaust port 7.As shown in FIG. , an exhaust fan 9 facing the center of the guide plate 5
The suction force is uniformly distributed around the combustion tube 3',
The soot rising above the grill 2' is sucked into the space of the yakiniku pot body 1 through the upper smoke exhaust hole 3''. This situation is shown in FIG.

As shown in FIG. 4, the soot that flows into the clean room of the clean section B from inside the space of the yakiniku machine body 1 due to the operation of the exhaust fan 9 is primarily filtered by the sponge filter 13. In addition, in the cleaning section B, exhaust fans 9 and 1 are provided at the exhaust ports 7 and 19, respectively.
7 is installed, and the soot flows only one way through the outlet 19. Therefore, first, carbon powder and other various solid powders, liquid or gaseous oil, etc. are filtered by the sponge filter 13.
Next, the soot filtered by the sponge filter 13 is filtered again when passing through the nonwoven fabric filter 14. All of the electrically charged dust that passes through the next electrostatic dust collector 15 is adsorbed by the electrode plate (dust collection plate) of the dust collector. This dust collector is a conventional dust collector, in which a plurality of cathode plates and anode plates are arranged facing each other with a slight distance between them, and a high DC voltage is applied to each plate to form electrostatic charges. Therefore, all of the charged particles passing between the opposing + and - dust collecting plates of the electrostatic dust collector 15 are attracted to the collecting plates by the electric attraction force. This is meaningful when used in combination with an ordinary small dust collector, and the structure of the dust collector itself is generally known.

After all particulate solid powder such as suspended matter present in the soot is collected by a sponge filter and an electrostatic dust collector, all odor is absorbed by the carbon filter 16 containing activated carbon particles and removed. Finally, carbon monoxide, ammonia, nitrogen gas, etc. decomposed during baking are purified into harmless gases by ozone ₀₃ generated by an ordinary ozone generator. Even if the purified gas is discharged into the room through the exhaust port 19, the air is odorless and dust-free, so it is not harmful to the human body.

The ozone generator is a normal one, which generates ozone ₀₃ through corona discharge between a high-pressure oscillating vacuum tube and an externally coated metal grid, and the generated ozone converts carbon monoxide into harmless carbon dioxide. let It also decomposes various harmful gases such as nitrogen compounds generated from fish and meat and removes odors. The functions of ozone, such as bleaching and sterilizing properties, are well known, and it is meaningful to incorporate them into the present invention.

(Effect of the invention) Due to the above-mentioned effects, the present invention does not require any complicated and unsightly structures such as smoke exhaust pipes or hoppers on the outside of the yakiniku machine body, so it not only has a neat appearance but also can be used freely and easily. The Yakiniku pot can be transported and moved. In addition, it can remove all the heavy soot and smoke generated when grilling meat, and it is more convenient and sanitary to use than traditional yakiniku pots, making it convenient for homes and business offices without polluting indoor furniture or air. It has an effect that can be used for.
