Second, in addition to simply cleaning the electric water heater, you can also find the after-sales department to maintain it regularly every year to strengthen the maintenance of the electric water heater and eliminate possible safety hazards. If you find something wrong with the parts of the electric water heater, don't disassemble and replace them yourself. The sealing requirement of electric water heater is very strict, and unprofessional operation can easily damage the electric water heater.
Users who turn on the water heater power all the year round should always check whether the water heater is normal, and if there is any abnormality, they should find the after-sales department for maintenance in time. If the electric water heater is not used for a long time, the power supply should be turned off and the water in the water tank should be drained to prevent the water tank from being corroded by water. If there is any abnormality, it should be sent to the maintenance point for maintenance in time. It is recommended to replace the thermostat and heater at the designated maintenance point every three years.
Third, remember to turn off the power switch when not using the electric water heater. When you use the electric water heater for the first time, please fill it with water and then drain it. Pay attention to cut off the power supply so as to clean the pipes and water tanks at the first time. When using the water storage electric water heater, fill it with cold water first, and then electrify it for heating. If there is water flowing out after opening the hot water valve, it means that the water storage is appropriate and electricity can be supplied.
Case Restoration At 6 o'clock on the evening of the 27th, a female body was found in the bathroom of a rented house in Fenghuang New Village, Longhua District, Haikou City.
Chen Mou, a junior from Baoting, Hainan, is still in the internship stage, sharing this two-bedroom apartment with a male roommate.
According to neighbors, the bathroom door was locked at that time, and the male roommate didn't see her out for a long time after she came back, so she called the police. The police rushed to the scene and broke in and found Chen Mou lying naked in the bathroom, showing no signs of life.
Chen Mou's father was heartbroken when he heard the news. According to him, when her daughter was found, her leg skin was burnt into a paste, which was suspected to be caused by leakage of water heater during bathing.
It is reported that the homicide was ruled out by the technical department of Longhua Branch of Haikou Public Security Bureau, and it was initially confirmed that it was an accident caused by water heater leakage, which was handed over to the safety supervision department for investigation and disposal.
How to prevent leakage ①? First of all, whether the water heater leaks electricity depends on the water heater itself, not whether you connect the hot water outlet with the wall, ground wire, etc. Secondly, because there is no guarantee that the wall potential of your bathroom is the same as your body potential when taking a bath, if your body potential is lower than the wall potential, then if the water heater leaks electricity, the current will pass through the human body first, causing the danger of electric shock.
If your bathroom has equipotential connection terminals, you can lead a wire from above to the metal connection of the water heater outlet, so that when the water heater leaks electricity, the current will flow away from the connection to protect personal safety.
② Choose qualified products from regular manufacturers.
(3) Reasonable installation as required (especially grounding wire and dedicated line).
④ Select qualified accessories (wires, sockets, etc.). ).
⑤ Take certain protective measures (install leakage protector).
⑥ Follow the instructions.
⑦ Regular maintenance
(8) Generally, the service life of a water heater is only 6-8 years. If the water heater exceeds 6-8 years, it depends on the quality, frequency of use and maintenance. It is best to call professionals to check at home to avoid potential safety hazards caused by negligence and forced use. For example, if the motor is used for a long time, the connector will be loose and there will be a danger of short circuit, and the leakage protection switch will also fail under special circumstances.
How to get an electric shock to save yourself? In the first few seconds after electric shock, people are in a state of mild electric shock, and people's consciousness has not been lost. Reasonable and orderly judgment and disposal is the key to successful liberation.
After getting an electric shock, it is not as "electricity will attract people" as usually imagined. Just because alternating current will cause continuous muscle contraction, there will be a phenomenon of grasping the power supply more and more tightly after electric shock.
At this point, the person who gets an electric shock can quickly grasp the insulation layer of the wire with the other hand and pull the wire out of his hand to get rid of the electric shock.
If the electric appliance is fixed on the wall when getting an electric shock, you can push the wall with your feet and lean back at the same time to get rid of the power supply with the help of your body's weight and external force. Ask for help from people around you immediately. If you feel unwell, you should go to the hospital for treatment.
How to give electric shock first aid to others? In short: the correct rescue method-let the electrocuted person leave the power supply, but make sure not to be electrocuted.
1 First of all, you must cut off the power supply, turn off the switch or connect the wires and appliances with insulation, or cut off the wires with a wooden handle axe (dry). Never pull an electric shock directly with your hand.
2. If you are unconscious, you should immediately loosen the collar and belt of the coat that affects your breathing, so that it is in a supine position, with your head tilted back, remove foreign bodies from your mouth, take out your dentures, and keep your respiratory tract unobstructed.
3. Breathing and heartbeat stopped, and cardiopulmonary resuscitation (CPR) was immediately on the scene. At the same time, they should be sent to the hospital for treatment immediately, and pay close attention to the patient's condition on the way.
