Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhausters, in particular to a spiral smoke exhaust channel structure of a kitchen smoke exhauster. Background Art

[0002] A kitchen hood, also called a range hood, is an electrical appliance used in the kitchen to absorb the fumes produced during cooking. The range hood can prevent the fumes from spreading in the kitchen, keep the air in the kitchen fresh, and prevent the fumes from polluting the walls and furniture. The range hood is usually designed to be hung above the stove. When turned on, the fan inside it will generate a strong suction force to suck the fumes into the device and then discharge them through the exhaust duct.

[0003] Traditional smoke exhaust channels are mainly designed in straight or curved lines. This design is simple, effective, and easy to clean and maintain. However, when exhausting oil smoke, the natural rise of hot air and the sinking of cold air may cause chaotic airflow, reduce smoke exhaust efficiency, and may also cause smoke backflow. Especially when the wind is strong or the windows and doors are open, it is not easy to form a stable airflow, so sometimes smoke will escape to other areas of the kitchen. In view of this, we propose a spiral smoke exhaust channel structure for kitchen smoke exhaust fans. Utility Model Content

[0004] The utility model aims to provide a spiral smoke exhaust channel structure of a kitchen smoke exhauster to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A spiral air duct is provided at the top of the vertical air duct. The spiral airflow can enhance the rising force of the air, help the hot air to rise and be discharged more quickly and effectively, thereby improving the smoke exhaust efficiency. An air duct cross pipe is provided at the end of the spiral air duct away from the vertical air duct. A windproof component is provided at the output end of the air duct cross pipe. The windproof component includes a rectangular exhaust pipe connected to the air duct cross pipe. A windshield plate is rotatably connected between the front and rear sides of the inner wall of the rectangular exhaust pipe and close to the left side. When the smoke extractor is working, the windshield plate will be blown open by the airflow in the smoke exhaust channel, thereby discharging the smoke. When the smoke extractor is not working, the windshield plate will close the rectangular exhaust pipe, thereby preventing external airflow from entering the rectangular exhaust pipe. The spiral air duct can form a continuous and stable airflow, which can help prevent the backflow of oil smoke during the exhaust process and reduce the re-dissipation of oil smoke and odor into the kitchen together with the windproof component.

[0008] Preferably, an annular mounting plate is provided at the bottom of the outer wall of the air guide riser, and the annular mounting plate is mounted on the smoke exhaust end of the smoking machine by bolts, so that the air guide riser is mounted on the smoking machine.

The liquid collecting bottle is made of transparent plastic material, which is convenient for the user to check the remaining capacity in the liquid collecting bottle so that the user can clean it in time.

[0011] Preferably, a frame-shaped mounting plate is provided on the right side of the outer wall of the rectangular exhaust pipe, and the frame-shaped mounting plate is installed on the indoor wall by bolts. The left side of the rectangular exhaust pipe passes through the wall to the outside, so that the rectangular exhaust pipe can be fixed on the wall, thereby fixing the position of the wind protection component.

[0012] Preferably, a U-shaped block is provided at the bottom of the inner wall of the rectangular exhaust pipe. When the windshield sheet is not blown up by the airflow in the air guide cross pipe, the right side of the windshield sheet fits with the left side of the U-shaped block, which limits the windshield sheet and prevents the windshield sheet from rotating to the right, thereby ensuring that the windshield sheet closes the rectangular exhaust pipe.

[0014] 1. The spiral smoke exhaust channel structure of the kitchen range hood can enhance the rising force of the air through the spiral airflow, helping the hot air to rise and be discharged more quickly and effectively, thereby improving the smoke exhaust efficiency. When the range hood is working, the wind shield plate will be blown open by the airflow in the smoke exhaust channel to discharge the smoke. When the range hood is not working, the wind shield plate will close the rectangular exhaust pipe to prevent the outside airflow from entering the rectangular exhaust pipe.

The windproof component 4 includes a rectangular exhaust pipe 40 connected to the air guide cross pipe 3. A windshield plate 41 is rotatably connected between the front and rear sides of the inner wall of the rectangular exhaust pipe 40 and close to the left side. When the smoke extractor is working, the windshield plate 41 will be blown open by the airflow in the smoke exhaust channel to discharge the smoke. When the smoke extractor is not working, the windshield plate 41 will close the rectangular exhaust pipe 40 to prevent external airflow from entering the rectangular exhaust pipe 40. The spiral air duct 2 can form a continuous and stable airflow, which, together with the windproof component 4, can help prevent the backflow of oil smoke during the exhaust process and reduce the re-dissipation of oil smoke and odor into the kitchen.
