/kloc-in the summer of 0/940, the German boy Schnord and his girlfriend Mark came to Munich after graduation, hoping to start a new life here. Soon, the two men were hired as employees by Siemens at that time. However, because both families are poor and have just joined the work, Empty Pocket has to rent a house with only 10 square meters in the suburbs of Munich.
In order to save money, Schnord and Mark choose to cook at home after work. However, after several months of persistence, Mark couldn't stand it because the room was small and the ventilation was not good. Cooking fumes can't be dispersed for a long time, and even clothes and quilts smell of fumes. When Mark was cooking, Schnord had opened all the doors and windows, but the effect was not satisfactory. Later, he simply moved the cooker to cook outdoors. There was no oil smoke, but it was inconvenient, especially in cold winter.
The famous German philosopher Hegel said: "Creative thinking needs rich imagination." Schnord's imagination is quite rich. His first thought was to partition all the cookers with wooden boards, which was equivalent to setting up a small kitchen independently in the room. However, although the lampblack can't enter the sleeping place for the time being, it is still indoors and will eventually penetrate into the room. Moreover, the space in the small kitchen is too small, and Mark will be choked by lampblack every time he cooks, which makes Schnord even more uncomfortable. One day, Schnord thought that there was a chimney in the fireplace in his hometown, so that even if the fireplace was in the house, there was no smoke at all. The more he thought about it, the more excited he became: wouldn't adding a chimney to the kitchen solve the problem? However, when he installed the chimney on the kitchen window, he was disappointed. The chimney couldn't emit oil smoke until he was inspired by a tornado.
One day, Schnord and Mark took part in an outing organized by the company. Just as they were having fun, a tornado hit them. Fortunately, they evacuated in time and escaped the strong wind. It was late when they got home, and they were all exhausted. They are even more depressed at the thought of cooking and putting up with suffocating smoke.
Schnord blamed himself very much. How can he stay away from the lampblack? He couldn't sleep all night, lying in bed thinking hard, thinking that the tornado he met during the day could actually lift the roof, and his eyes lit up: if a tornado formed in the kitchen, wouldn't the lampblack be pumped out? Man-made tornadoes don't seem difficult. There are many turbofans in the company. If the angle and direction of the blades are adjusted, suction will naturally form in the kitchen. The next day, Schnord came to the company and asked an old master to help him make a turbofan that can pump air. If he got the treasure, he immediately asked for leave to go home and put it at the chimney mouth, then connected the power supply and let the fan turn. He made a fire in the kitchen and found that the smoke obviously turned in the direction of the chimney. He succeeded. But he felt that the smoke was very slow, so he simply moved the chimney mouth to the top of the cooker, and as soon as the smoke came out, it was directly smoked away. Later, after a series of renovations, Schnord's kitchen was really no longer troubled by oil fumes.
Soon, under the persuasion of the master, Schnord applied for a patent for invention, named range hood. 194 1 year, Schnord assigned this patent to Siemens. After further research and development and beautification, a series of range hoods with beautiful and practical appearance are quickly introduced to the market. Since then, range hoods have gradually entered thousands of households.
