Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a large-scale cooking range hood. Background Technology

[0002] Existing large-scale cooking range hoods are mainly used in commercial kitchens (such as restaurant and hotel kitchens) or large canteens, where chefs generate a lot of oil fumes during cooking. The cooking range hoods can use their powerful suction to remove these fumes from the cooking area in a timely manner, preventing them from spreading in the kitchen.

[0003] However, existing large-scale cooking range hoods do not have a structure to increase the oil fume travel distance or a structure to change the oil from a gaseous state to a liquid state. As a result, some oil fumes are discharged directly without effective treatment. They also do not have a self-cleaning function. Due to the large size and complex parts of large-scale range hoods, manual cleaning requires disassembling multiple parts. The entire cleaning process often takes several hours or even longer and requires professional cleaning tools and detergents, which brings great inconvenience to users. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a large cooking range hood. In use, multiple baffles can increase the travel of oil fumes inside the outer shell. When the oil fumes pass through these baffles, due to inertia and collision with the baffle surfaces, the oil in the oil fumes will more easily adhere to the baffles. Through the heating plate on the baffle, heating can change the physical state of the oil fumes, causing the oil to change from a gaseous state to a liquid state, thereby precipitating the oil in the oil fumes and making it adhere to the baffle. A small amount will flow down the baffle into the collection box. When not in use, the heating plate can heat the oil adhering to the surface, and the electric push rod can push the push plate to push the oil adhering to the heating plate and the baffle surface downward. The oil will flow down the baffle into the collection box for collection, thereby achieving self-cleaning and reducing the need for manual intervention. Users do not need to spend a lot of time and energy to disassemble the range hood for cleaning, making the cleaning process simple and quick.

[0005] This utility model also provides a large cooking range hood as described above, comprising: a wall, a shell fixedly connected to the front surface of the wall, an air inlet provided on the shell, multiple baffles fixedly connected to the inner surface of the shell, the multiple baffles being inclined downwards at a 25-degree angle and staggered, each of the multiple baffles having a through hole, a heating plate fixedly connected to the inner wall of the through hole, sleeves fixedly connected to the upper and lower surfaces of each of the multiple baffles, an electric push rod fixedly connected to the inner surface of the sleeve, and a side surface of the electric push rod being fixed... A sealing plate is connected to the sleeve. The other end of the electric push rod is fixedly connected to a push plate, which is slidably connected to a baffle and a heating plate. A sliding groove is provided on the outer shell, extending to the outer surface of the outer shell. The sliding groove is located below the baffle. A collection box is slidably connected to the inner surface of the sliding groove, which is located below the baffle. A fan pipe is connected through the upper surface of the outer shell. A bracket is fixedly connected to the inner wall of the fan pipe. A motor is fixedly connected to the inner surface of the bracket. A fan blade is fixedly connected to the output end of the motor.

[0006] According to the present invention, a large cooking range hood is provided with an exhaust pipe on the upper surface of the outer shell, and the other end of the exhaust pipe extends through to the rear surface of the wall.

[0007] According to the present invention, a large cooking range hood is provided, wherein a frame is connected through the side surface of the outer shell, and a viewing window is fixedly connected to the inner wall of the frame.

[0008] According to the present invention, a large cooking range hood is provided with a gas collection hood fixedly connected to the front surface of the outer shell, and the gas collection hood is located in front of the air inlet.

[0009] According to the present invention, a large cooking range hood is provided, wherein a lamp holder is fixedly connected to the lower surface of the outer shell, and a supplementary light is fixedly connected to the lower surface of the lamp holder.

[0010] According to the present invention, a large cooking range hood is provided with a mounting plate fixedly connected to the side surface of the outer shell, and the mounting plate is provided with mounting holes.

[0011] According to the present invention, a large cooking range hood is provided on the wall, and a fixing pin is movably connected to the inner surface of the mounting hole, the fixing pin extending into the interior of the through hole.

[0012] According to the present invention, a large cooking range hood is provided with a handle fixedly connected to the side surface of the collection box, and a protective cover is fixedly connected to the outer surface of the handle. Beneficial effects

[0013] Compared to existing technologies, this large cooking range hood utilizes multiple baffles to increase the travel distance of cooking fumes within the outer casing during use. As the fumes pass through these baffles, the oil in the fumes adheres more easily to the baffles due to inertia and collisions with the baffle surfaces. Heating plates on the baffles alter the physical state of the fumes, causing the oil to change from a gaseous to a liquid state, thus releasing the oil from the fumes and allowing it to adhere to the baffles. A small amount flows down the baffles into the collection box. When not in use, the heating plates heat the oil adhering to their surfaces, and an electric push rod pushes a plate to move the oil down the heating plates and baffle surfaces, allowing it to flow down the baffles into the collection box for collection. This achieves self-cleaning, reducing the need for manual intervention. Users no longer need to spend a lot of time and effort disassembling the range hood for cleaning, making the cleaning process simple and quick. Attached Figure Description

[0023] Multiple baffles 23 are fixedly connected to the inner surface of the outer casing 9 to increase the travel of the oil fumes, thereby increasing the contact between the oil fumes and the heating plate 24, and enabling better oil extraction. The multiple baffles 23 are staggered and tilted downwards at a 25-degree angle. Each baffle 23 has a through hole, and the inner wall of the through hole is fixedly connected to the heating plate 24 to heat the oil fumes, thereby extracting the oil from the oil fumes. Sleeves 17 are fixedly connected to the upper and lower surfaces of the multiple baffles 23. An electric push rod 18 is fixedly connected to the inner surface of the sleeve 17. A sealing plate 25 is fixedly connected to the side surface of the electric push rod 18 to close the sleeve 17 when the electric push rod 18 retracts, preventing oil fumes from entering. The sealing plate 25 is movably connected to the sleeve 17. A push plate 19 is fixedly connected to the other end of the electric push rod 18 to push the oil fumes downwards. The push plate 19 is slidably connected to the baffles 23 and the heating plate 24. A sliding groove 26 is provided on the outer casing 9.

[0024] The chute 26 extends to the outer surface of the housing 9 and is located below the baffle 23. A collection box 20 is slidably connected to the inner surface of the chute 26 for collecting oil fumes. A handle 7 is fixedly connected to the side surface of the collection box 20, and a protective sleeve 6 is fixedly connected to the outer surface of the handle 7.

A motor 14 is fixedly connected to the inner surface of the bracket 15. A fan blade 16 is fixedly connected to the output end of the motor 14.

[0025] Working principle: Multiple baffles 23 increase the travel distance of oil fumes inside the outer casing 9. As the oil fumes pass through these baffles 23, due to inertia and collisions with the surface of the baffles 23, the oil in the oil fumes adheres more easily to the baffles 23. Heating by the heating plate 24 on the baffles 23 changes the physical state of the oil fumes, causing the oil to change from a gaseous state to a liquid state, thereby releasing the oil from the oil fumes and causing it to adhere to the baffles 23. A small amount will flow down the baffles 23 into the collection box 20. When not in use, the heating plate 24 can heat the oil adhering to the surface. The electric push rod 18 can push the push plate 19 to push the oil adhering to the surface of the heating plate 24 and the baffles 23 downwards. The oil will flow down the baffles 23 into the collection box 20 for collection, thereby achieving self-cleaning.
