(1) Unscrew the screw that fixes the net cover.

(2) Soak the removed filter screen cover in warm water of neutral detergent for 5- 10 minutes.

(3) Clean the dirt in the pores of the filter with a soft plastic brush, and then dry it with a dry rag.

(4) Install the filter screen cover as it was before disassembly.

(5) After installation, check whether the oil circuit of the appliance is unblocked and whether the sealing ring on the volute can be sealed.

(6) Please clean the filter screen cover according to the cycle specified in the manual.

Do not disassemble and clean the electrical connection and airflow seal inside the range hood frequently. Frequent disassembly and cleaning of the sealing ring will easily lead to aging and deformation, and oil stains will easily enter the electrical connection parts of electrical appliances, affecting their safety performance and reducing the service life of the range hood.

Clever cleaning of filter screen of range hood

There is too much oil on the filter screen of range hood, which is difficult to clean. Do you have this problem at home?

An audience member called us. He said that the filter screen of their range hood was too oily and he bought it earlier. The after-sales service of the range hood he bought long ago is not very good. Because now some seem to send it once a year, or once every two years for free replacement. At that time, the after-sales service was not so good, so I always used that filter. The oil on the screen almost crystallizes and becomes solid. Is there any good way?

Cleaning the range hood, the most important thing is the filter hood. If it is not cleaned for a long time, the service life of the range hood will be greatly reduced. Moreover, due to excessive accumulation, it will drip into delicious food and affect the quality of food. Generally, we will use detergent or detergent powder to clean, but detergent and detergent powder can only remove dirt on the surface, and it is difficult to clean stubborn oil stains. Look, this is the grease stain on the filter cover. These oil stains are mainly decomposed from lampblack. After cooking oil is heated, heated and condensed again, the mechanical state of oil molecules will become larger, thus forming waste cooking oil. This waste cooking oil is very viscous and difficult to clean. So, what can we do to easily remove the stubborn oil stains on this filter cover?

Wrap the filter cover of the range hood with newspaper first, and then wrap it with towel. All right, next, the protagonist, the washing machine. Put the wrapped filter cover into the washing machine, turn the washing machine to the spin-drying position, remember not to add water to the washing machine, and start the washing machine to spin-dry the filter cover of the range hood.

How's it going? The effect is not bad. Look, most of the grease on the filter cover has been thrown into the newspaper. Then why can the washing machine remove all stubborn oil stains from the filter cover? Let's consult an expert. Please ask Chang Li, professor of physics at Capital Normal University, to answer our questions. Excuse me, why can the washing machine clean the oil stains on the filter cover?

Expert:

Because when the filter screen cover is surrounded by newspaper, surrounded by towel and put into the washing machine, the oil droplets attached to it are moving in a circular motion, so the faster the filter screen rotates, the faster the oil droplets move. Then, under the centrifugal action, the oil droplets will fly out of the filter cover to achieve the purpose of separating the oil droplets from the filter cover. The faster the filter cover rotates, the more separation will be.

Many people think it is too easy to throw this filter into the washing machine after watching our demonstration, but we can't just hurt our expensive home appliance washing machine. Because the current filter screens are made of this metal, which is very strong. After it is really thrown, it is easy to damage the drum or impeller, and the bag is very knowledgeable. Look, we have put the newspaper and towels on this table. These are bandages. They are bandages for this filter. In fact, the first layer of newspaper is very particular, because the newspaper has certain adsorption, so we should make this newspaper thicker, say, two layers, and then wrap this filter. Pack more newspapers. No problem. But not strong enough. Why do you wrap towels? One is to protect our roller. If you turn like this, sometimes you will slip, of course you will drive. You must work very hard when wrapping this towel. You see, in this way, you must tie it firmly, and then tie it diagonally in the other direction. This is foolproof. In fact, this towel still has some functions. The two-layer towel wrapped in this way means that you can't wash clothes unless all the oil inside is thrown onto the drum. You see, after this towel is wrapped tightly, you can feel it again, that is, the metal of the filter screen is sharp and soft. Do you think tying a two-layer knot will spread out in the washing machine? Wrap it in plastic cloth or simply put it in a plastic bag. I think we should put a plastic bag, because this oil will spill after it is thrown out. If it spills into the inner cylinder of our washing machine, we can't wash clothes, which is very troublesome. After wearing it like this, it means that there are already two layers here, then put it into a complete plastic bag and turn it over.

Special reminder: If the filter screen of the range hood is not cleaned for a long time, it may affect the use effect of the range hood, so it is best to wash and wipe it frequently.
