01Harm of long-term non-cleaning of range hood
Easy to damage the motor
Authorities have done such tests: the range hood works without cleaning for a long time, and the current when starting is 3-6 times the normal value, so it is easy to burn the motor.
Shorten the service life of range hood
When the range hood is used for a long time, oil stains accumulate over a long period of time, and a large amount of oil stains are oxidized to form acidic substances, which corrode the range hood, cause the range hood to rust, accelerate the aging of the range hood and shorten the service life.
Greatly reduce the suction of range hood
The accumulation of oil pollution is one of the main reasons for the decline of suction of range hood. A large amount of oil pollution is stuck on the impeller and flue of range hood, which will definitely increase the weight of impeller and the rotational kinetic energy of wind wheel, make the operation of range hood more difficult and greatly reduce the suction.
Increased noise affects work and rest
Oil stains adhere to the rotating shaft of the motor, which will become stubborn stains and become more difficult to clean after a long time. When running, the friction force is increased, resulting in more obvious noise. At the same time, the load of the motor is increased and the load of the fan is increased, resulting in abnormal operation of the fan.
It is easy to cause fire
The accumulation of oil dirt will undoubtedly increase the load of all parts, and the operation of the hood will become more difficult, which will easily lead to line failures and fire hazards.
This shows how important it is to clean the hood
Wash yourself, you can't clean it

02Harm of not cleaning water heater
I heard that not washing the water heater for three years is equivalent to taking a bath with sewage. In order to find the answer, a curious netizen really opened his own water heater, and the scene he saw was really shocking ...
After closing the triangle valve, unscrew the nuts of the hot and cold nozzles ... After a long hurry, the residual water in the water heater finally came out. Look at what kind of water comes out of the liner of this water heater that has not been washed for three years ...
This is the water that came out at the beginning, so it's OK, to say it cleanly.
This is the water that came out after five minutes, which is a bit stunned! ! !
Harm of not cleaning water heater:
Because the thermal conductivity of scale is very poor, which is only one tenth to several hundred percent of copper, iron and other metals, if a large amount of scale is attached to the heating rod of electric water heater, it will greatly affect the heating efficiency. According to professional tests, when the thickness of scale is 1.5mm, the electric water heater will consume 6% more electricity; When the scale thickness reaches 5mm, it will consume 15% more energy; When the scale thickness is 8mm, the increased power consumption increases to 34%.
Scale contains a variety of chemical components, and long-term precipitation and accumulation increase harmful substances in water, which may lead to skin allergy; Clay, microorganisms and bacteria are constantly renewed for a long time, forming many pollutants. These dirty things can cause a variety of skin diseases, making children or women with low resistance sometimes feel itchy and red spots after taking a bath.
Scale adsorbed on the heating surface of the water heater, especially in the pipe, is difficult to remove. Cleaning frequently is needed for descaling, which increases the maintenance cost, which not only consumes manpower, material resources and financial resources, but also damages the heating surface and greatly shortens the service life of the water heater due to frequent descaling by mechanical and chemical methods.
After scale is produced in the water heater, the evaporation will be reduced due to poor heat transfer, which will reduce the pressure of the equipment. If scaling occurs in the water pipe, the flow cross-sectional area will be reduced, which will increase the flow resistance of water circulation. In severe cases, the pipeline will be completely blocked, which will destroy the water circulation. In severe cases, it will cause tube explosion accidents.
During normal operation, the heating rod of water heater transfers heat to water or other medium quickly after being heated, and the temperature difference between them is very large. However, the heat of the heating rod coated with scale is difficult to be transferred to water because it is blocked by scale, so the temperature will rise sharply and the intensity will drop significantly. Over time, water heaters will cause damage and even electricity leakage, which is very unsafe.
So many hazards
