How to clean the grease in the hood, 3 generations of hot dry cleaning (heating oil) technology comparison
Â
Every family has the same pain point. After one year of use of the range hood, a layer of grease is stuck on the inner wall of the volute of the hood. As the service life increases, the grease in the range hood increases, and the inside of the volute appears. The smaller the space, the more the wind is blocked and the suction of the hood is greatly reduced, so that the smoke can not be extracted and the noise becomes louder. This is why some hoods have just bought back and used suction, and the effect of hooding is also very good. However, in less than half a year, the suction of the hood is greatly reduced, and the soot is completely unable to be smoked, and the noise is also increased.
Â
The thick oil level of the range hood does not only affect the use effect, but also affects our health. Grease is composed of grease, water and soot. Grease is a very dirty thing. It will breed a lot of bacteria, rot and smell in a humid and warm environment. This is why there are always some old-fashioned kitchens that open the kitchen door. The strange smell, this smell is similar to the taste of the sewer.
Â
As a result, there have been three generations of automatic cleaning hoods on the market to help the hood to extend its service life :
Â
The first generation: fine mesh filtering, represented by a flower.
The hood oil net with a small mesh diameter is used to filter most of the grease and impurities in the soot, so that the inner cavity of the hood is relatively clean and it is difficult to accumulate and form grease. However, because the oil mesh has a very small mesh hole, it is easy to be blocked by the oil droplets in the oil smoke. After the mesh is blocked, the oil smoke can not be extracted, and the cleaning frequency of the oil net is increased, resulting in a family who often cooks, and the fine oil after three days. The net was blocked and the fumes could not be pumped, which means that the oil net would be cleaned in three days. In addition, the oil net is of poor quality and is easily rotted during cleaning and cannot be cleaned. At the same time, the range hood will also have problems such as fume extraction, loud noise, and stinking.
Â
The second generation: washing, represented by an emperor and a certain.
The turbine internal cavity is cleaned by water or steam to achieve the effect of removing oil from the inner chamber. It has been found that the damage rate of household appliances is high in the two months from March to April each year . Because these two months are the return tide days, commonly known as the south wind days, the humidity in the air will increase, thus increasing the failure rate of home appliances. If water or steam is added to the hood, the probability of moisture in the electrical components will increase, resulting in a malfunction of the hood. Further long-term accumulation of grease hood internal cavity is formed, with a few 10-watt small motor spray to clean water can imagine its intensity can go there, but also simply does not wash clean. Moreover, the method of water washing or steam washing is very troublesome. It is necessary to add water manually, even if a professional cleaning agent is added, and it is necessary to wait until the cleaning is finished to clean the water stains splashed on the cooking table, which is time consuming and laborious. Water and oil do not blend together, resulting in more difficult to dry, resulting in a large number of bacteria breeding, easy to cause residual grease in the lumen to rot and smell.
Â
The third generation, patented technology of Kangbao hot dry cleaning (heating oil) :
The principle of patented technology of Kangbao hot dry cleaning (heating oil) : the main component of grease is grease, the melting point of oil is 55 °C, Kangbao uses the principle of oil to melt, and a layer of heating film is attached to the surface of the volute of the machine. The volute can be heated to around 70 °C. The oil on the inner wall of the volute is cracked and melted by thermal radiation, and the oil is melted into a liquid and then discharged from the hood by the oil guiding tube. Hot dry cleaning is quick and convenient. Just press the automatic heating button to heat it for 9 minutes, then automatically start the gear for 1 minute to drain the oil, then automatically shut down. No need to wait, no need to remove a screw, no need to change a oil net, not a drop of water, really one-button automatic cleaning. Convenient, fast, save money and worry.

Automatic hot dry cleaning technology, to prevent the use of smoke machines after a period of time, can not smoke, smoke, noise, odor and other phenomena. Easy one button, heat decontamination, suction is not reduced, keep the smoke machine long-lasting suction! Do not remove the screws, do not change the oil net, not even a drop of water, convenient and fast, save money and worry.
In fact, what people usually call a pinhole camera does not use a pinhole lens. Pinhole lens refers to a lens that uses the principle of small hole imaging to obtain images. It is inexpensive and simple in principle, but its fatal weakness is that too little light passes through the small hole, resulting in too long exposure time. Taking photos with a pinhole lens in sunlight can take anywhere from a few minutes to a dozen minutes, especially when shooting at night with exposure times of up to several hours. Obviously, for a camera that shoots dozens to dozens of frames per second, it cannot meet the requirements. Pinhole lenses cannot be applied to cameras, so there is no "pinhole" camera in the strict sense. As is customary, a miniature camera using a fisheye lens, a flat lens or a conical lens is called a pinhole camera.
According to the lens, the lens of the pinhole camera can be divided into three types: fisheye lens, flat lens and conical lens; according to the photosensitive element used, it can be divided into charge coupled element and complementary metal oxide semiconductor; According to the data transmission method, it can be divided into two categories: wireless cameras and wired cameras.
