The advantage of this kind of kitchen is to reduce the cost of the catering industry through centralized large-scale procurement and intensive production. production costs.

The oil fume generated when cooking in the central kitchen is generally discharged to the purification device through a specific pipe for purification treatment. Among them, the oil fume fan is more commonly used. The oil fume fan is a type of kitchen appliance used to purify the kitchen environment. It can purify the kitchen environment. The waste burned by the stove and the harmful oil fume generated during the cooking process are quickly extracted and discharged outdoors. According to the different emission positions, it can be divided into: upper exhaust type oil fume fan, side exhaust type oil fume fan and lower exhaust type oil fume fan. A common oil fume fan is mainly composed of a casing, an air duct, a wind wheel, a silencer layer and a drive motor. When in use, the drive motor drives the wind wheel to rotate to discharge the oil fume in the air duct.

Due to the lack of a corresponding oil collection mechanism, the existing oil fume fans cannot separate and collect the oil pollution generated during use, making the oil fume fans easily affected by oil pollution during use and resulting in poor extraction effects, which reduces the efficiency of the oil fume fans. The stability of use, at the same time, increases the labor intensity of subsequent cleaning of the range fume fan and reduces the convenience of use of the range fume fan.

Example:

Referring to Figures 1 to 4, an oil collection mechanism of a fan includes a box 1, and an exhaust assembly is provided in the box 1. The exhaust assembly draws away the oil fume generated during cooking and then discharges it. The exhaust assembly adopts existing technology. The air extraction assembly includes a wind wheel 2. A volute 202 is fixedly connected to the box 1. The wind wheel 2 is rotatably arranged in the volute 202. A motor 201 for driving the wind wheel 2 to rotate is fixedly connected to the box 1, and the box 1 There is a front cover 101 fixedly connected to the front cover 101, and an oil net 102 is detachably connected to the front cover 101, which also includes components such as a check valve and a lighting lamp. When in use, after the power is turned on, the motor 201 drives the wind wheel 2 to rotate at a high speed. , causing an air pressure difference between the inside and outside of the air inlet and the exhaust port of the range hood, so that the oil smoke can rotate and accelerate with the air in the inner cavity of the volute 202 and be blown outdoors. At the same time, in the process of removing the oil smoke, the oil smoke The middle part of the high-temperature oil particles are thrown to the inner wall of the volute 202 under the action of the centrifugal force of the wind wheel 2. After condensing into oil droplets, they flow into the collection chamber 103 under the action of gravity. There is a separation cylinder 4 fixedly connected in the box 1. There are multiple sets of baffles 5 fixedly connected in the separation cylinder 4. There are at least three groups of baffles 5. We have chosen six groups here, and the six groups of baffles 5 are in the form of Regularly arranged, according to the air intake direction, it is divided into one-two, one-two formations. The frontmost piece blocks the front of the two rear gaps, and so on. When the oil fume flows at high speed, its movement is changed multiple times through the baffle 5. direction, due to inertia, oil particles will collide with the baffle 5, and then condense into oil droplets and flow from the oil discharge hole 403 to the collection chamber 103, which can reduce the content of oil in the oil fume entering the volute 202, and help reduce the amount of oil in the wind wheel. 2 and the volute 202 are affected by oil pollution and the extraction effect is deteriorated, and the input end of the separation tube 4 is connected to the air inlet channel where the oil screen 102 is installed on the front cover 101, and the output end of the separation tube 4 is connected to the wind wheel 2 Communicated, a shower plate 6 is fixedly connected to the separation cylinder 4, and a plurality of sets of nozzles 601 for spraying and cleaning the baffle 5 are fixedly connected to the shower plate 6. After being used for a period of time, the nozzles 601 can be installed in the separation cylinder 4. Spray cleaning fluid, which can speed up the fall of oil droplets accumulated on the baffle 5. The wind wheel 2 will also absorb part of the cleaning fluid, which has a certain cleaning effect on the baffle 5, the wind wheel 2 and the volute 202, reducing the The labor intensity of subsequent cleaning of the oil fume fan is reduced, the number of cleanings is reduced, and the convenience of use of the oil fume fan is improved. The box 1 is provided with a liquid supply part for supplying liquid to the shower plate 6; a collection cavity 103 is provided in the box 1 , an oil collection box 7 for collecting oil dirt is slidably connected in the collection chamber 103. One end of the oil collection box 7 is connected to the collection chamber 103, and an oil drain hole 403 is provided on the separation cylinder 4 to communicate with the collection chamber 103. There are two disconnected chambers in the oil box 7. One of the smaller chambers can collect the oil dripping from the oil screen 102, and the other larger chamber is used to collect the dripping from the separation cylinder 4 and the volute 202. of oil stains.

When in use, the oil fumes sucked into the volute 202 by the wind wheel 2 will first pass through the separation tube 4 for a certain degree of oil fume separation, which reduces the burden of the wind wheel 2 and the volute 202 in handling oil pollution, and helps to reduce the oil pollution between the wind wheel 2 and the volute 202. The shell 202 is affected by oil pollution and the extraction effect deteriorates. After a period of use, the nozzle 601 sprays cleaning fluid in the separation cylinder 4. The cleaning fluid can speed up the fall of oil droplets accumulated on the baffle 5, affecting the baffle. 5, the wind wheel 2 and the volute 202 all have a certain cleaning effect, which reduces the labor intensity of subsequent cleaning of the oil fume fan, reduces the number of cleanings, and improves the convenience of use of the oil fume fan.

Referring to Figure 1, Figure 3 and Figure 4, in order to improve the interception of oil pollution in the oil fume by the baffle 5 and reduce the temperature of the surface of the baffle 5 as much as possible, we have a water channel 501 in the baffle 5, and the separation tube 4 A water inlet pipe 401 and a drainage pipe 402 are fixedly connected. One end of the water channel 501 is connected to the water inlet pipe 401, and the other end of the water channel 501 is connected to the drainage pipe 402. The water inlet pipe 401 can be connected to the faucet, and there is heat exchange in the water discharged by the drainage pipe 402. It has a certain temperature rise and can be used to wash dishes, etc., speed up the dissolution of cleaning products such as detergent, and improve the cleaning effect. When high-temperature oil fume collides with the baffle 5 at normal temperature or a certain temperature lower than normal temperature, the oil fume will flow due to the temperature reduction. Due to the influence of inertia, a large number of oil particles will be intercepted by the baffle 5, which can improve the interception effect of the baffle 5.

After adding the cleaning agent into the liquid distribution tank 3 At this time, the water source with a certain temperature can be transported into the liquid distribution tank 3 through the branch pipeline, which helps to speed up the dissolution of the detergent and water. The output end of the water pump 301 is connected with the shower plate 6, and there is a rotating connection in the liquid distribution tank 3. The stirring rod 302 can prevent the cleaning liquid in the liquid preparation tank 3 from settling and affecting the decontamination effect. The box 1 is provided with a driving part for driving the stirring rod 302 to rotate. When in use, the driving part rotates with the stirring rod 302 , which can prevent the cleaning liquid in the liquid distribution tank 3 from settling and affecting use.
