  Since the grill of Patent Document 1 is mounted on a built-in type gas stove, the exhaust cylinder portion protrudes greatly upward from the upper wall of the grill chamber, and the vertical length of the exhaust passage is cooked. It is long enough to form an exhaust flow (draft).

That is, the cooked exhaust flowing in the exhaust passage flows while forming an upward flow (draft) while being heated in the exhaust cylinder, and as a result, the external air is burned in the combustion-type heating unit. It will flow into the heating chamber as working air.
And when the vertical length of the exhaust passage is sufficiently long, the cooking exhaust can be appropriately flowed while forming the upward flow (draft) while sufficiently heating the cooking exhaust in the exhaust cylinder part, As a result, the external air can be appropriately flowed into the heating chamber as combustion air for the combustion-type heating unit.

  In other words, in a grill equipped on a built-in type gas stove, a lath net as a flame extinguishing member for cooking exhaust and an inclined guide plate extending downward from the lower end of the lath net are provided with a food item placing portion in the exhaust opening. By arranging it in a state corresponding to the upper side portion of the cooking chamber, the vertical length of the exhaust passage is sufficient even if the flow resistance (exhaust resistance) of the cooked exhaust flowing upward from the heating chamber to the exhaust passage increases. Therefore, by sufficiently heating the cooking exhaust in the exhaust cylinder, it is possible to flow the cooking exhaust while properly forming the upward flow (draft). It can be appropriately flowed into the heating chamber as combustion air for the heating section.

  By the way, as a gas stove, in addition to the built-in type, there is a so-called table-type gas stove that is mounted on the top of a stove stand or the like. In addition, since it does not protrude greatly above the upper wall of the grill chamber, the heating amount for heating the cooked exhaust in the exhaust cylinder part does not tend to be so large.

  For this reason, in a grill equipped on a table type gas stove, when a flame extinguishing member provided in a grill equipped on a built-in type gas stove is used, the flow resistance (exhaust resistance) of cooking exhaust flowing from the heating chamber to the exhaust path increases. As a result, cooking exhaust cannot be made to flow properly while forming an upward flow (draft), and as a result, external air is made to flow appropriately inside the heating chamber as combustion air for the combustion-type heating unit. There is a possibility that it cannot be done.

  The present invention has been made in view of the above circumstances, and its purpose is to cook while forming an upward flow even when the vertical length of the exhaust passage is short, while making the flame extinguishing action properly exhibited. The object of the present invention is to provide a grill capable of appropriately flowing exhaust gas.

The grill of the present invention includes a gas combustion type heating unit that is formed in a cylindrical shape extending in the front-rear direction in a form including an exhaust opening at the rear end and heats the food placed on the food placing unit. A heating chamber;
An exhaust cylinder portion continuously provided in a posture toward the upper side from the rear end of the heating chamber in a state of forming an exhaust passage for guiding the cooked exhaust from the exhaust opening to an upper exhaust outlet;
A flame extinguishing member installed inside the exhaust cylinder in a form including a porous portion through which the cooking exhaust passes, and the characteristic configuration thereof is:
The exhaust pipe body in the up-and-down quadrangular cylindrical shape that constitutes the flame-extinguishing member has a front surface portion that forms the porous portion from a position corresponding to the food placing portion in the exhaust opening portion. The upper end of the front portion is positioned closer to or in close contact with the front side surface of the exhaust cylinder portion, and between the rear surface portion and the rear side portion of the exhaust cylinder portion. In a state of forming a rear passage through which the cooking exhaust flows,
An internal passage through which the cooking exhaust flows upward is formed inside the exhaust cylinder,
A guide path for guiding the cooked exhaust to the rear passage is formed between a lateral side surface portion of the exhaust cylinder and a lateral side surface portion of the exhaust cylinder portion.

  That is, the cooking exhaust discharged from the upper part of the food product mounting portion at the exhaust opening of the heating chamber flows to the front portion of the exhaust cylinder, and a part of the cooking exhaust is exhausted through the porous portion. The fluid flows into the cylinder, and then flows upward in the internal passage of the exhaust cylinder while forming an upward flow (draft).

  Of the cooking exhaust that has flowed to the front surface of the exhaust cylinder, the remaining cooking exhaust that does not pass through the porous portion is guided between the lateral side surface of the exhaust cylinder and the lateral side surface of the exhaust cylinder. It flows to the rear passage between the rear surface portion of the exhaust cylinder and the rear side surface portion of the exhaust cylinder through the passage, and then flows upward in the rear passage while forming an upward flow (draft). .

  Of the cooking exhaust exhausted from the upper side portion of the food product mounting portion in the exhaust opening of the heating chamber, between the lateral side surface portion of the exhaust cylinder and the lateral side surface portion of the exhaust cylinder portion The cooking exhaust that has flowed directly to the induction path flows through the induction path to the rear passage between the rear surface of the exhaust cylinder and the rear side of the exhaust cylinder, and then forms an upward flow (draft). However, it will flow upward in the rear passage.

  In addition, the cooking exhaust discharged from the lower part of the food product mounting portion in the exhaust opening of the heating chamber flows to the lower portion of the exhaust cylinder, and the cooking exhaust is inside the exhaust cylinder. The fluid flows upward through a rear passage formed on the rear side of the passage and the exhaust cylinder.

  The cooking exhaust flowing in the internal passage heats the exhaust cylinder, and the cooking exhaust flowing in the induction passage and the rear passage heats the exhaust cylinder. The temperature of the body will rise, and cooking exhaust that rises and flows through the internal passage of the exhaust cylinder will be heated sufficiently by the exhaust cylinder, so it will flow upward in the internal passage of the exhaust cylinder. The cooking exhaust to be performed can be appropriately flowed upward though passing resistance (exhaust resistance) by passing through the porous portion.

  That is, the exhaust gas that rises and flows in the internal passage of the exhaust cylinder is made to recover the heat held by the cooking exhaust discharged from the exhaust opening of the heating chamber to the exhaust cylinder. The cooking exhaust that rises and flows in the internal passage of the exhaust cylinder, even if the length of the exhaust cylinder is short, is made to flow upward while forming an upward flow (draft) while heating at Since the exhaust cylinder can be heated sufficiently, the flow resistance (exhaust resistance) of the cooked exhaust flowing upward in the internal passage of the exhaust cylinder is increased by passing through the porous portion. The cooking exhaust that flows upward in the internal passage of the exhaust cylinder can be appropriately flowed while forming an upward flow (draft).

  Incidentally, the cooking exhaust flowing through the guide passage and the rear passage does not pass through the porous portion, and therefore flows in a state where the flow resistance (exhaust resistance) is small, and the cooking exhaust flowing through the rear passage is Since the cooking exhaust discharged from the upper end of the internal passage tends to be sucked upward, the cooking exhaust flowing through the rear passage can be appropriately flowed upward while forming an upward flow (draft).

  As described above, the cooked exhaust discharged from the exhaust opening of the heating chamber can be appropriately flowed while forming an upward flow even if the vertical length of the exhaust path is short.

  In addition, even if a fire is generated in the heating chamber due to burning of the food placed on the food placing portion, etc., if the generated flame tries to flow through the internal passage, the cooling action of the porous portion When the generated flame flows through the guide passage and the rear passage, it is cooled by the contact with the exhaust cylinder or the exhaust cylinder, so that the flame is extinguished. It is possible to suppress the fired flame from overflowing from the exhaust outlet.

  In short, according to the grill of the present invention, cooking exhaust can be made to flow appropriately while forming an upward flow even if the vertical length of the exhaust passage is short while properly exerting the flame extinguishing action.

  Further, according to a further characteristic configuration of the grill of the present invention, the exhaust cylinder is provided in a rearward tilted position located on the rear side toward the upper end side and extending upward to a height corresponding to the exhaust outlet. In the point.

  That is, since the exhaust cylinder is provided in a rearward tilt position located on the rear side toward the upper end side and extending upward to a height corresponding to the exhaust outlet, the exhaust cylinder is set in the rear tilt position. By making the length of the exhaust cylinder as long as possible and extending the exhaust cylinder upward to a height corresponding to the exhaust outlet, the exhaust cylinder can be effectively used while fully utilizing the entire length of the exhaust cylinder. The length of the cylinder for use can be made as long as possible.

  Therefore, by increasing the length of the exhaust cylinder as much as possible, the heat recovered by the exhaust cylinder from the cooked exhaust can be increased as much as possible, and the cooked exhaust is more appropriately formed while forming a strong upward flow (draft). Can be made to flow.

  In short, according to the characteristic configuration of the grill of the present invention, cooking exhaust can be more appropriately flowed while forming a strong upward flow (draft).

  Further, the grill according to the present invention is further characterized in that a soup pan is provided below the food placing portion, and a flame generated in the soup pan passes through the bottom of the exhaust cylinder and the internal passage and the rear portion. The porous suppression part which suppresses flowing to a channel | path exists in the point provided in the form extended below from the lower end of the said front-surface part of the said exhaust cylinder.

  That is, since the juice receiving tray is provided below the food placing portion, for example, oil that falls from the food when the fish or the like is placed on the receiving net as the food placing portion and cooked by heating. The bottom of the heating chamber can be prevented from being soiled by receiving and collecting the etc. in the soup pan.

  In the state where oil or the like is collected in the soup pan, there is a possibility that a flame may be generated in the soup pan, but when the generated flame passes through the porous suppression portion, the quenching action is performed by the cooling portion. Therefore, it is possible to prevent the flame from flowing into the internal passage and the rear passage of the exhaust cylinder and overflowing from the exhaust outlet.

  Further, when the flame generated in the soup pan flows upward while being guided by the suppression portion, when the flame passes through the porous portion of the exhaust cylinder, the flame is extinguished by the cooling action of the porous portion. Moreover, when the flame flows to the rear passage through the guide passage, it is cooled and extinguished by contact with the exhaust cylinder or the exhaust cylinder, so that the flame is prevented from overflowing from the exhaust outlet. be able to.
