Description

Technical Field

[0001] This utility model relates to the field of barbecue equipment technology, specifically a new type of smokeless grill pan. Background Technology

[0002] Currently, with the continuous improvement of people's living standards, there are more and more ways to cook food, and the requirements are also getting higher and higher. Electric grill pans, as a modern and popular barbecue equipment, are widely favored by users. However, electric grill pans produce oil fume pollution during the grilling process, so the structure of electric grill pans needs to be further improved.

[0003] Smokeless baking pans on the market only use side ventilation or large-area perforated ventilation to remove smoke, and they must use high-powered fans, which seriously affects the temperature of the baking pan surface. Moreover, this method cannot effectively collect the oil fumes generated on the baking pan surface, resulting in poor oil fume collection efficiency. Furthermore, it is very difficult and inconvenient to disassemble and clean the filter after filtration. The incompletely collected oil fumes are harmful to the human body, and the high-powered fans also make the overall product consume more electricity, which is very environmentally unfriendly.

[0004] Therefore, there is an urgent need for a new type of smokeless baking pan to solve the above problems. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a novel smokeless baking pan to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel smokeless baking pan includes a baking pan and a base. The baking pan is mounted on a baking pan support and located at the top of the support. A centrifugal fan is installed at the bottom of the base to draw smoke from inside the base. A lower tray is installed at the top of the base. A cooling duct is installed inside the base and mounted on the lower tray. The bottom of the cooling duct is connected to the inside of the centrifugal fan. An upper tray is connected to the top of the cooling duct. A smoke collector is installed on the upper tray and its bottom is connected to the inside of the cooling duct. A baking pan support is installed around the smoke collector to support the baking pan. A filter screen is installed on the inner wall of the bottom of the smoke collector. An oil collection box is installed inside the smoke collector and located above the filter screen. The baking pan is fixedly mounted by the baking pan support and covers the smoke collector.

[0008] As a further embodiment of this utility model: the baking pan has a flat surface and a raised or recessed center, and a number of smoke extraction holes are distributed on the baking pan, with the bottom of the smoke extraction holes having a dripping structure.

[0009] As a further embodiment of this utility model: the baking tray and the smoke collector are interlocked and sealed, and the smoke collector is provided with two smoke extraction holes around its perimeter.

[0010] As a further embodiment of this utility model: the oil receiving box has a ring-shaped structure, and the hollow ring-shaped design of the oil receiving box is misaligned with the smoke extraction hole on the baking tray, and the hollow ring-shaped structure of the oil receiving box forms an oil receiving groove.

[0011] As a further embodiment of this invention, the filter screen is filled with activated carbon.

[0012] As a further embodiment of this utility model: heating tubes are provided on both sides of the top of the base, and the heating tubes are installed on the baking tray support.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In terms of smoke extraction technology, this utility model abandons the previous method of large-diameter smoke extraction hole in the center of the baking pan or smoke extraction on the side of the baking pan, and adopts the principle of low-pressure smoke extraction on the pan surface, which simplifies the smoke extraction method and ventilation structure and improves smoke extraction efficiency.

[0015] 2. A smoke extraction hole is set on the surface of the baking tray to allow oil to drip directly onto the oil collection box, preventing oil from remaining on the baking tray and generating more smoke under the high temperature of the baking tray; a second smoke extraction hole is set around the smoke collector to realize the smoke extraction function of the baking area under the baking tray.

[0016] 3. The staggered design of the exhaust hole of the baking tray and the ventilation hole in the middle of the oil collection box allows the oil fumes to be initially separated, reducing the filtering burden on the filter screen.

[0017] 4. A two-layer smoke extraction system is adopted, which achieves smoke extraction function on both the baking tray surface and the baking area. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In this embodiment of the utility model, please refer to Figures 1 to 4 A novel smokeless baking pan includes a baking pan 1 and a base 9. The baking pan 1 is mounted on a baking pan support 5 and located at the top of the support 5. A centrifugal fan 10 is installed at the bottom of the base 9 to draw smoke away from the interior of the base 9. A lower tray 8 is installed at the top of the base 9. A cooling duct 7 is installed inside the base 9 and mounted on the lower tray 8. The bottom of the cooling duct 7 is connected to the interior of the centrifugal fan 10. An upper tray 6 is connected to the top of the cooling duct 7. A smoke collector 3 is installed on the upper tray 6, and the bottom of the smoke collector 3 is connected to the interior of the cooling duct 7. The baking tray support 5 is installed around the smoke collector 3 to support the baking tray 1. A filter screen 11 is installed on the inner wall of the bottom of the smoke collector 3. An oil collection box 2 is installed inside the smoke collector 3, and the oil collection box 2 is located above the filter screen 11. The baking tray 1 is fixedly installed by the baking tray support 5 and covers the smoke collector 3. The baking tray 1 and the smoke collector 3 are interlocked and sealed, and the smoke collector 3 is provided with a second smoke extraction hole around its perimeter. The oil collection box 2 has a ring structure, and the hollow ring design of the oil collection box 2 is misaligned with the first smoke extraction hole on the baking tray 1. The hollow ring structure of the oil collection box 2 forms an oil collection groove.

[0025] When the user grills on the grill pan 1 and upper tray 6, the centrifugal fan 10 operates, creating negative pressure inside the device. Gas above the grill pan 1 and in the area between the grill pan 1 and upper tray 6 is drawn into the smoke collector 3, creating a low-pressure zone and converging airflow. This allows the fumes to be directly drawn into the smoke collector 3. Simultaneously, after entering the smoke collector 3, the fumes are displaced due to the annular structure of the oil collection box 2, and through inertia, the gas... Large grease particles are collected in the oil collection box 2, while small grease particles are filtered directly through the filter screen 11 via the central air duct of the oil collection box. The filtered smoke enters the cooling air duct 7 for cooling and is discharged by the centrifugal fan 10, completing the entire smoke removal process. A snap-fit ​​sealing structure is provided at the junction of the baking tray 1, the smoke collector 3, and the oil collection box 2, so that the smoke collector 3 can be better sealed. Furthermore, the edge of the oil collection box 2 is higher than that of the smoke collector 3, so that the grease can only drip into the oil collection box 2 and avoid dripping into the machine.

[0026] As one embodiment of this utility model, please refer to Figures 1 to 4 The baking tray 1 has a flat surface and several sets of smoke extraction holes are distributed on the baking tray 1, and the bottom of the smoke extraction holes is a drip structure.

[0027] The baking pan 1 has a flat structure, and the smoke extraction holes are arranged in an orderly manner, which allows the heat of the baking pan 1 to be transferred to the center. The entire flat surface can be used to heat and grill food. The smoke extraction holes of the baking pan 1 are surrounded by a downward-sloping edge structure, which allows oil to drip at a fixed position, making it easy to collect and process the oil.

[0028] In one embodiment of this utility model, the filter screen 11 is filled with activated carbon.

[0029] The activated carbon used in the process can not only adsorb oil and impurities in the gas, but also remove odors from the exhaust gas, thus improving the cleanliness of the exhaust gas.

[0030] As one embodiment of this utility model, please refer to Figures 1 to 4 Heating tubes 4 are provided on both sides of the top of the base 9, and the heating tubes 4 are installed on the baking tray support 5.

[0031] Heating element 4 is electrically connected to the power cord. Heating element 4 is the main heat source for grilling and can provide heat to the grilling areas of grilling pan 1 and upper tray 6 at the same time, ensuring that grilling pan 1 and upper tray 6 can be grilled normally.

[0032] The working principle of this utility model is as follows: When the user grills on the grill pan 1 and the upper tray 6, the centrifugal fan 10 operates, creating negative pressure inside the device. The gas above the grill pan 1 and the area between the grill pan 1 and the upper tray 6 is drawn into the smoke collector 3, thus making the area above the grill pan 1 and the area between the grill pan 1 and the upper tray 6 a low-pressure zone. This creates a converging airflow, allowing the fumes to be directly drawn into the smoke collector 3. Simultaneously, after entering the smoke collector 3, the fumes are displaced due to the annular structure of the oil collection box 2. Through inertia, large grease particles in the gas are collected in the oil collection box 2, while small grease particles are filtered directly through the filter screen 11 via the central air duct of the oil collection box. The filtered fumes enter the cooling air duct 7 for cooling and are then discharged by the centrifugal fan 10, completing the entire smoke removal process.
