Description

[Detailed description of the invention] This invention relates to a new improvement of a yakiniku grill table used in yakiniku restaurants and the like.

In recent years, yakiniku restaurants have become filled with oil smoke, and in order to prevent the restaurant from becoming contaminated, the oil smoke generated during yakiniku is forcibly sucked downward and discharged outside the restaurant through ducts placed under the floor. A floor exhaust type yakiniku grill table has been proposed and is being put into practical use.

Such floor exhaust type ducts tend to trap hot air inside the duct, compared to open type ducts that raise oily smoke and suck it out through one or more exhaust holes installed in the wall or ceiling. The oil content in the oil smoke adheres to the inner surface of the duct, and dust, etc., may adhere to it, causing a risk of ignition, resulting in a high risk of fire.

This invention was made to prevent the risk of fire occurring in such floor exhaust type Yakiniku grill tables, and will be explained in detail below with reference to the drawings.

In the figure, reference numeral 1 denotes a table body having a table 3 on the top, which has a grill chamber 2 equipped with a grill burner for yakiniku as is conventionally known. An exhaust chamber 4 is disposed below the grill chamber 2 to suck air downward without raising it.

A grease filter 5 for separating oil from oil smoke is installed inside the exhaust chamber 4, and a water tray 6 is placed above the table body 1.
It is arranged so that it can be put in and taken out from the front in a drawer style.

An exhaust duct 7 passing under the floor is connected to the lower end of the exhaust chamber 4, and contaminated air within the exhaust chamber 4 is forcibly sucked in by an appropriate fan device and exhausted to the outside.

A door 8 is formed on the front surface of the table main body 1 in order to allow the water dish 6 to be taken in and taken out freely, and a door 9 is further formed on the upper front surface of the exhaust chamber 4.

The oil smoke generated in the grill chamber 2 is sucked through exhaust guide paths 10 that are open on both sides of the upper part of the grill chamber 2, as shown in FIG.

The exhaust guide path 10 descends vertically to the upper surface of the water tray 6, is bent at a right angle, and extends horizontally on the upper surface of the water tray 6.

The oil smoke sucked into the exhaust guide path 10 and descending is turned horizontally at right angles on the upper surface of the water tray 6, and curves into a C-shape as shown by the dotted line in FIG. 2-3.

As a result of this turning of the smoke, the smoke comes into contact with the surface of the water tray 6 and is cooled, and at the same time, oil and relatively large foreign substances in the smoke are separated by the centrifugal force at the time of turning and captured in the water. Ru.

- A flue 11 penetrating vertically is formed in the center of the water tray 6, and an oil separation means 12 having a baffle structure is disposed continuously at the upper end of the flue 11.

As shown in FIG. 3, the oil separation means 12 has a U-shaped turned passage 13 disposed obliquely, an outlet 14 of the passage 13 connected to the flue 11, and a passage 15 turned at right angles. and continues to the top surface of the water tray 6.

The width of the passage 13 gradually decreases from the population 15 toward a U-shaped turning point 16, and increases again after passing the turning point 16.

As a result, the oil smoke that has entered the passage 13 is compressed toward the turning point 16, its flow velocity increases, and it collides with the wall 17 located at the turning point and perpendicular to the passage.

Due to the collision, oil and fine particles in the smoke are separated from the smoke and accumulate in the reservoir 18.

Further, after passing the turning point 16, the smoke is dissolved from the previous compression and expands, so the flow rate decreases and the oil and particulate matter in the smoke separates and similarly accumulates in the reservoir 18.

As described above, according to the yakiniku grill table of this invention, the oil smoke generated in the grill chamber 2 is sucked into the exhaust guide path 10 and descends, and is turned at right angles on the upper surface of the water tray 6. Sometimes the smoke is cooled by contact with water and
Centrifugal force during rotation separates oil and foreign matter from the smoke and traps it in water.

Thereafter, the oil and particulates in the smoke are further removed by the oil separation means 12 having a baffle structure, and the smoke enters the exhaust chamber 4 and is discharged to the outside via the exhaust duct 7. Because the temperature is low, there is little risk of heating the inside of the duct 7, and since there is little oil and particulate matter, there is almost no chance of it adhering to the inside of the duct 7, so the risk of fire outbreak can be almost completely avoided. be.
