Description

Technical Field

[0001] The invention relates to the technical field of oil fume treatment, in particular to a large-space high-efficiency oil fume purification device. Background Art

[0002] A range hood, also known as a range hood, is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove and can quickly extract the waste from the stove combustion and the oil smoke generated during the cooking process that is harmful to the human body and discharge it outdoors. At the same time, it condenses and collects the oil smoke to reduce pollution, purify the air, and has anti-toxic and explosion-proof safety protection functions. The range hood needs to be cleaned regularly, but the interval between each cleaning will cause the oil smoke inside the range hood to solidify, making it very inconvenient to clean. In addition, the accumulation of oil smoke may block the oil exhaust channel, resulting in a decrease in the purification effect. Therefore, a device is needed to automatically clean the oil exhaust channel for subsequent cleaning. Summary of the invention

The upper end of the hinged tube is hinged to the lower surface of the exhaust plate, the lower side of the hinged tube is fixedly connected to the outer wall of the connecting block, the rear side of the outer wall of the connecting block is hinged to the upper inner wall of the fixing plate, the air cavity is arranged inside the fixing plate, the connecting block is provided with a connecting cavity in the middle, the interior of the hinged tube is communicated with the air cavity inside the fixing plate through the connecting cavity, the lower inner wall of the fixing plate is fixedly connected to the outer wall of the rubber sheet, the rubber sheet is provided with a fixing hole, and the scraping mechanism is arranged inside the fixing hole.

[0006] Preferably, the scraping mechanism includes a fixed tube, a spring sheet, a scraper, a rubber leather, and an elastic telescopic rod. The outer wall of the fixed tube is fixedly connected to the inner wall of the fixed hole, the outer wall of the scraper is slidably connected to the inner wall of the fixed tube, the outer wall of the scraper is connected to the inner wall of the fixed tube through the spring sheet, the lower side of the fixed tube is fixedly connected to the outer wall of the rubber leather, a cavity is formed between the outer wall of the fixed tube and the outer wall of the rubber leather, the upper outer wall of the elastic telescopic rod is hinged to the lower outer wall of the fixed tube through a torsion spring, and the lower end of the elastic telescopic rod is in contact with the outer wall of the rubber leather.

[0007] Preferably, the lower surface of the rubber sheet contacts the upper surface of the oil drain bottom plate, and the lower end of the scraper contacts the upper surface of the oil drain bottom plate.

[0008] Preferably, two exhaust ports are provided on the upper side of the exhaust plate, and the two exhaust ports are both arranged on the upper side of the wind wheel.

[0009] Preferably, the lower end of the exhaust plate is located on the upper side of the oil box.

[0010] The present invention provides a large-space high-efficiency oil fume purification device, which has the following beneficial effects:

[0011] 1. This large-space high-efficiency oil fume purification equipment starts the motor to drive the wind wheel to collect the oil fume when in use. The oil fume is finally discharged from the inside of the wind wheel and attached to the outer wall of the exhaust plate. The air is discharged from the upper side of the wind wheel to achieve the purpose of filtering and purifying the oil fume. Since the oil and water thrown out by the wind wheel can flow into the interior of the oil box through the outer wall of the exhaust plate and the oil discharge bottom plate, it can work continuously at high intensity and achieve the purpose of purifying large-space oil fume.

[0012] 2. After the use of the large-space high-efficiency oil fume purification equipment, the speed of the exhaust plate will slowly decrease due to the stopping of the work of the wind wheel, which will reduce the centrifugal force caused by inertia, and make the fixed plate drop due to gravity, so that the outer wall of the rubber sheet will contact the outer wall of the oil drain bottom plate. As the exhaust plate rotates, the rubber sheet will scrape and gather the oil and water on the oil drain bottom plate, so that it will flow into the inside of the oil box, thereby reducing the amount of solidified oil and water, which is convenient for subsequent cleaning.

[0013] 3. When the impeller of the large-space high-efficiency oil fume purification equipment is working, the exhaust plate rotates at a high speed, which causes the fixed plate and the hinged tube to be lifted up due to the centrifugal force generated by inertia and retracted into the exhaust plate. At the same time, the slider moves to the left due to the centrifugal force, so that the right side of the air cavity is inhaled through the connecting tube, and the rubber sheet is retracted into the fixed plate, thereby reducing the contact area between the rubber sheet and the outside world and reducing the oil fume pollution it is subject to.

[0014] 4. For this large-space high-efficiency oil fume purification equipment, when the hinged tube falls, the elasticity of the elastic rope drives the slider to reset, so that the gas inside the air cavity returns to the inside of the hinged tube through the connecting tube, so that the rubber sheet expands and makes the rubber sheet better contact the surface of the oil drain bottom plate. At the same time, the scraper is pushed out of the rubber sheet by the gas, so that the scraper contacts the surface of the oil drain bottom plate, so that it scrapes the stubborn stains on the surface of the oil drain bottom plate, making it easier for the oil and water to be collected.
