Abstract

This utility model provides a large cast iron baking plate, including a cast iron baking plate body with symmetrically arranged heat-insulated handles on both sides. The interior of the cast iron baking plate body has a ventilation cavity, the bottom of the body has an exhaust vent, and the outer surface of the body has a smoke exhaust vent. Both the exhaust vent and the smoke exhaust vent are connected to the ventilation cavity. In use, by creating a ventilation cavity inside the cast iron baking plate body and providing an exhaust vent at the bottom and a smoke exhaust vent on the side, an airflow channel is formed. This creates a "fire-drawing tube" effect, where the air in the ventilation cavity is heated and its density decreases during fuel combustion. The high-temperature flue gas rises rapidly and is discharged through the smoke exhaust vent, continuously creating a low-pressure zone within the ventilation cavity. This causes cold air from the bottom of the furnace to be drawn into the furnace to replenish oxygen, forming a self-circulating airflow and improving the completeness of fuel combustion in the oven.

Description

Technical Field

[0001] This utility model relates to the field of baking plate technology, and in particular to a large cast iron baking plate. Background Technology

[0002] A grill plate is a cooking utensil used in conjunction with an oven for grilling. Large, flat grill plates are often used for dishes like teppanyaki. These grill plates are typically large, box-like structures with an open top, and are usually made of cast iron or stainless steel.

[0003] Because of its large size, when placed on the oven, it will cover a large area of ​​the oven, resulting in insufficient oxygen intake and incomplete fuel combustion.

[0004] Incomplete combustion of fuel in an oven leads to low combustion efficiency and produces a large amount of carbon monoxide. This reduces cooking efficiency and increases overall toxicity.

[0005] Therefore, this application proposes a large cast iron baking plate to solve the problem of incomplete combustion of fuel in the oven mentioned above. Utility Model Content

[0006] In view of the shortcomings of the prior art mentioned above, the purpose of this utility model is to provide a large cast iron baking plate to solve the problem of incomplete combustion of fuel in the oven caused by the baking plate mentioned in the prior art.

[0007] To achieve the above and other related objectives, this utility model provides a large cast iron baking plate, including a cast iron baking plate body, wherein heat-insulating handles are symmetrically arranged on both sides of the cast iron baking plate body. The cast iron baking plate body has a ventilation cavity inside, an exhaust hole at the bottom of the cast iron baking plate body, and a smoke exhaust hole on the outer surface of the cast iron baking plate body. Both the exhaust vent and the smoke vent are connected to the ventilation cavity.

[0008] Preferably, the exhaust vent is located at the center of the bottom of the cast iron baking plate body, and there are multiple exhaust vents that are equidistantly distributed.

[0009] Preferably, the smoke vent is located on the side of the cast iron baking plate body between the two heat-insulated handles, and the bottom of the smoke vent is flush with the bottom of the ventilation cavity.

[0010] Preferably, the number of exhaust holes is several, and the several exhaust holes are distributed on one side of the cast iron baking plate body.

[0011] Preferably, the top of the cast iron baking plate body is provided with a heating groove, and the interior of the heating groove is provided with a number of raised support ribs at equal intervals.

[0012] Preferably, the heating tank has an outwardly extending protective mechanism on its side, which covers the smoke exhaust port.

[0013] Preferably, the protective mechanism includes a flame baffle plate, one end of which is provided with a connecting strip, and the flame baffle plate is fixed to the side of the heating tank by the connecting strip.

[0014] Preferably, the connecting strip is inverted U-shaped, the opening of the connecting strip is elastic, and the inner wall of the connecting strip abuts against the edge of the heating groove.

[0015] Preferably, the top of the flame baffle is provided with a receiving groove, which extends towards the bottom of the flame baffle.

[0016] Preferably, the length of the receiving groove is not less than the overall length of the smoke exhaust hole.

[0017] As described above, the large cast iron baking plate of this utility model has the following beneficial effects: 1. This utility model creates an airflow channel by setting a ventilation cavity inside the cast iron baking plate body, and setting an exhaust hole at the bottom of the cast iron baking plate body and a smoke exhaust hole on the side of the cast iron baking plate body. The exhaust hole and the smoke exhaust hole form a "fire tube". When the fuel is burning, the air in the ventilation cavity is heated and the density decreases. The high-temperature flue gas rises rapidly and is discharged from the smoke exhaust hole. A low-pressure zone is continuously formed in the ventilation cavity, which causes the cold air at the bottom of the furnace to be drawn into the furnace to supplement oxygen and form a self-circulating airflow, thereby improving the fuel combustion efficiency in the oven.

[0018] Meanwhile, the smoke exhaust vents inside the cast iron baking plate body can reduce the overall weight of the cast iron baking plate body and improve its portability.

[0019] 2. This utility model effectively prevents flames from directly escaping from the exhaust vent under the action of airflow by setting a protective mechanism on the side of the cast iron baking plate body to block the top of the exhaust vent, thus preventing injury to nearby cooking personnel or objects.

[0020] Meanwhile, the surface of the flame shield can be used to place grilled food. By heating the flame shield with flames or smoke coming out of the exhaust vent, the food can be kept warm.

[0021] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0029] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0030] like Figures 1-3 As shown, this utility model provides a large cast iron baking plate, including a cast iron baking plate body 1. Heat-insulating handles 13 are symmetrically arranged on both sides of the cast iron baking plate body 1. The heat-insulating handles 13 are used to facilitate the handling and placement of the cast iron baking plate body 1 during cooking. The heat-insulating handles 13 can be integrally cast with the cast iron baking plate body 1, and then a heat-insulating layer is fitted onto the outer surface of the heat-insulating handles 13 to achieve heat insulation.

[0031] The cast iron baking plate body 1 has an internal ventilation cavity 14, an exhaust vent 15 at its bottom, and a smoke exhaust vent 16 on its outer surface. Both the exhaust vent 15 and the smoke exhaust vent 16 are connected to the ventilation cavity 14, forming a ventilation channel similar to a "fire tube." During fuel combustion, the air in the ventilation cavity 14 is heated, reducing its density. The high-temperature flue gas rises rapidly and is discharged through the smoke exhaust vent 16, continuously creating a low-pressure zone within the ventilation cavity 14. This draws cold air from the furnace bottom into the furnace to replenish oxygen, forming a self-circulating airflow. This ensures sufficient oxygen in the oven, improving fuel combustion efficiency and safety during combustion.

[0032] like Figure 2 As shown, in some embodiments, the exhaust vent 15 of this invention is located at the center of the bottom of the cast iron baking plate body 1. This ensures that when the cast iron baking plate body 1 is placed on the oven, the exhaust vent 15 is directly facing the center of the oven, allowing it to fully face the combustion zone and thus improving ventilation efficiency. Multiple exhaust vents 15 are equidistantly distributed, further enhancing ventilation while maintaining the strength of the cast iron baking plate body 1.

[0033] like Figure 2 and Figure 3 As shown, in some embodiments, the exhaust port 16 of this invention is located on the side of the cast iron baking plate body 1 between the two heat-insulated handles 13, to avoid scalding the hands with hot air or flames when the cast iron baking plate body 1 needs to be taken out through the heat-insulated handles 13 during cooking. The bottom of the exhaust port 16 is flush with the bottom of the ventilation cavity 14. After prolonged use, soot may accumulate inside the ventilation cavity 14. At this time, the soot can be removed from the inside of the ventilation cavity 14 through the exhaust port 16 using a tool. The exhaust port 16, being flush with the ventilation cavity 14, can avoid obstructing the soot.

[0034] like Figure 2 As shown, in some embodiments, the number of exhaust holes 16 of this invention is several, and the several exhaust holes 16 are distributed on one side of the cast iron baking plate body 1. By setting the number and distribution area of ​​exhaust holes 16, the air circulation rate is improved, thereby further improving the combustion efficiency and completeness of fuel in the oven.

[0035] like Figure 1 As shown, in some embodiments, the top of the cast iron grill plate body 1 of this invention is provided with a heating groove 11 to limit the food being grilled, so as to prevent the food from accidentally slipping off during the grilling process. Several slightly raised support ribs 12 are evenly spaced inside the heating groove 11 to support the bottom of the food, increasing the contact area between the food and the cast iron grill plate body 1 while reducing the possibility of food sticking to the pan. At the same time, it can increase the oil yield of the food, allowing the oil produced during grilling to flow between the support ribs 12.

[0036] like Figure 4 As shown, in some embodiments, the heating tank 11 of this invention is provided with an outwardly extending protective mechanism 2 on its side. The protective mechanism 2 covers the top of the smoke exhaust hole 16 and is used to shield the area above the smoke exhaust hole 16. This prevents flames that are propelled by the airflow from shooting directly upwards from the smoke exhaust hole 16, reducing the risk of burns and smoke inhalation to operators grilling from the other side.

[0037] like Figure 5 As shown, in some embodiments, the protective mechanism 2 of this utility model includes a flame baffle 21, which is the main body for blocking the rise of flames and smoke. A connecting strip 22 is provided at one end of the flame baffle 21, and the flame baffle 21 is fixed to the side of the heating tank 11 by the connecting strip 22.

[0038] like Figure 5 As shown, in some embodiments, the connecting strip 22 of this utility model is inverted U-shaped. When installing the flame baffle 21, the flame baffle 21 is fixed by inserting the connecting strip 22 into the side of the heating groove 11 and by the inner wall of the connecting strip 22 abutting against the side of the cast iron baking plate body 1. This structure enables convenient installation and removal of the flame baffle 21. The opening of the connecting strip 22 is elastic, which allows the connecting strip 22 to be better clamped at the edge of the heating groove 11, and the inner wall of the connecting strip 22 abuts against the edge of the heating groove 11, thereby improving the stability of the flame baffle 21.

[0039] like Figure 4 and Figure 5 As shown, in some embodiments, the top of the flame-insulating plate 21 of this invention is provided with a receiving groove 23, where cooked food can be placed for storage. The receiving groove 23 extends towards the bottom of the flame-insulating plate 21, allowing the high-temperature smoke and flames escaping through the exhaust hole 16 to directly act on the edges and bottom of the receiving groove 23. When the bottom and sides of the receiving groove 23 are heated, the food in the receiving groove 23 can achieve a heat preservation effect.

[0040] like Figure 4 As shown, in some embodiments, the length of the mounting groove 23 of this utility model is not less than the overall length of the smoke exhaust hole 16, so that the bottom of the mounting groove 23 can come into contact with the high-temperature flue gas and flames over a large area, thereby improving the heating efficiency of the mounting groove 23.

[0041] In summary, the large cast iron baking plate of this utility model forms an airflow channel by setting a ventilation cavity 14 inside the cast iron baking plate body 1, and setting an exhaust hole 15 at the bottom of the cast iron baking plate body 1 and a smoke exhaust hole 16 on the side of the cast iron baking plate body 1. The exhaust hole 15 and the smoke exhaust hole 16 form a "fire tube". When the fuel is burning, the air in the ventilation cavity 14 is heated and the density decreases. The high-temperature flue gas rises rapidly and is discharged from the smoke exhaust hole 16. A low-pressure zone is continuously formed in the ventilation cavity 14, which causes the cold air at the bottom of the furnace to be drawn into the furnace to supplement oxygen and form a self-circulating airflow, thereby improving the combustion efficiency of fuel in the oven.

[0042] Meanwhile, the smoke exhaust hole 16 is provided inside the cast iron baking plate body 1, which can reduce the overall weight of the cast iron baking plate body 1 and improve the portability of the cast iron baking plate body 1.

[0043] This invention effectively prevents flames from directly escaping from the exhaust hole 16 under the action of airflow by setting a protective mechanism 2 on the side of the cast iron baking plate body 1 to block the smoke exhaust hole 16, thus avoiding injury to cooking personnel or objects in the vicinity.

[0044] Meanwhile, the surface of the flame shield 21 can be used to place grilled food. By heating the flame shield 21 with flames or smoke coming out of the smoke vent 16, the food can be kept warm.

[0045] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0046] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
