Introduction: In the daily after-sales maintenance of range hood products, many friends will encounter range hood products leakage, so for the range hood products, it is a need to be charged to work appliances, because it runs the work of the need to use electricity, so it will inevitably appear and electricity-related failures, shell leakage is a fault.
hood shell leakage causes and treatment
1, not installed grounding line or grounding line contact is poor (sometimes induced voltage), if necessary, re-install the grounding line, and make good contact.
2, the internal lines or connectors are damaged, resulting in the shell charged, check the internal lines and all the connectors, if necessary, with insulating tape for insulation.
3, the motor stator winding local insulation aging, resulting in shell charged, the fault generally need to dismantle the motor processing.
Prevent hood leakage measures
1. Update the aging equipment.
2. Regular inspection and maintenance of equipment in use.
3. Strengthen the inspection of electrical facilities, regular leakage protector test, to ensure that the leakage protection device sensitive tube.

Case 1: hood leakage of a life
August 23, 2009, He's mother at home to wipe a brand of range hoods were electrocuted death. Hengyang City Consumer Council staff called the manufacturer's representative and forensic view of the scene and evidence, the identification of the hood there are quality problems, the Consumer Council staff mediation, the consumer He was eventually compensated 423,300 yuan.
Case 2: oil extraction operations in a small room hood leakage
July 21, 2012, oil extraction operations in the first area of the cow twelve counts of post employees Guo Lili in the small room electrical equipment inspection tour, when she touched the exhaust hood shell, by the moment of electric shock. Subsequently, the station manager Guo Lei with a test pen on the exhaust hood body to check the electricity, found that the equipment shell has been charged 90V, timely report to the district. The electrician of the water and electricity company checked that, due to the aging of the circuit inside the range hood, the hood shell induced voltage, when a person touches the shell, the leakage current does not reach the action current of the leakage protector, so the leakage protector does not act. The result is that the hood shell is electrically charged.
Consumers need to buy formal safety performance higher hood products
Related hood products leakage accidents abound, so for the end user of the hood (consumer), the purchase of hood products need to pay attention to try to bone stores or regular shopping malls to buy hoods, do not want to cheap! The first thing you need to do is to go to a shopping website or a cheap store to buy a hood, because it's very difficult to maintain your rights after an accident.

hood shell leakage causes and solutions
1, grounding wire is not installed: we may not be unfamiliar with this statement, because the home of large appliances such as water heaters, refrigerators, air conditioning and so on, because of the need for more power, so in order to prevent leakage will be So in order to prevent leakage will install a special grounding line, hood also need to install a special grounding line, so when the hood leakage situation, may be due to the failure to install a special grounding line, want to solve the best in time to set up a special grounding line can be.
2, the internal line is damaged: there may be hoods inside the line of the problem caused by the hood leakage, such a situation may be caused by the hood inside the line of the aging of the impact of the emergence of the hood in the use of more frequent, almost every day in the use of the hood, so when the hood leakage it is necessary to check the internal line in a timely manner, encountered broken The aging of the situation, timely repair or replacement of new lines, the use of insulation tape wrapped.
3, motor damage: the hood motor is one of the main components, so when the hood motor damage occurs, it will also lead to the hood shell leakage, want to solve this situation, it is best to ask a professional master to solve, because the internal structure is more complex.
4, because now the hood smoke effect is better, so the use of power is also relatively large, so it is best to install the time, set a grounding line in advance, so as to ensure the safety of the hood, but also to maintain the hood's operating results, if the hood shell leakage should not be set up to the grounding line of the situation led to the situation, want to avoid this, the best to install the grounding line can be. Grounding wire can be.
5, the hood shell leakage. The reason is that the hood internal power line failure, such as internal street lines due to prolonged use, resulting in aging and damage to the situation, I hereby recommend that the hood should also regularly check the internal parts, timely repair or replacement of new parts, so as not to cause damage to other parts of the hood, the line is damaged, it is very likely that the hood shell is charged, so please ask professional The line is damaged, it is likely to have a hood shell with electricity, so please ask a professional master to check the line in time for repair.
6, because the hood is used frequently in the kitchen, as long as the start of cooking will appear fumes, by the hood to absorb clean, keep the kitchen hygiene, however, the kitchen is clean, the hood often absorb fumes will accumulate a large number of oil stains on the inside, a long time will cause damage to the motor, and the motor is damaged, it is very likely to cause the hood shell charged with electricity, the best solution to this situation is to use the hood to avoid damage to other parts of the hood, so please ask a professional master to check the line and timely maintenance. The solution is that the hood must be regularly cleaned, it is best to find a professional cleaning master for deep cleaning, and then ask the master to check the internal motor of the hood, timely maintenance can be.
