What are the commonly used household appliances?
microwave oven
This is a must for every family kitchen. Not only can you heat dishes and rice, but now many microwave ovens have the function of barbecue and steaming eggs and rice. I use my microwave oven to cook rice and warm milk, which is really convenient.
Cooking machine
In fact, the cooking machine is a mixer with comprehensive performance, which is the conditioning machine in the past. Compared with the past, its function has changed a lot, not just grinding, but also adding the functions of grinding and crushing, making shaved ice, making juice, making meat stuffing and so on.
Agitator
Although manual egg beating can control the fineness of egg liquid, it will take a long time to beat more eggs, and there are strict requirements for the degree of egg liquid when making cakes. Therefore, the manual eggbeater will be very tired and inefficient, and electric egg beater can help us solve this problem, which can not only control the speed but also change the strength of the eggbeater. It's like a mentor.
Egg steamer
Have you ever worried that the eggs are not cooked well? Don't bother now. The egg steamer only needs a little water to make you eat a perfect boiled egg. It is an excellent helper for marinated eggs and tea eggs.
Electric casserole
In the past, using casserole to make soup often depended on the temperature and temperature. Since there is an electric casserole, there is no need to use a hot stove to make soup. Those electric casseroles that lock water will not dry for five days.
Common sense of safe use of household appliances
First, the common sense of safe use of household appliances
(1) When buying household appliances, you should buy qualified products recognized by the state, and don't buy fake and shoddy products with "three noes". Read the product manual carefully after purchase, pay attention to the voltage and power, and do not exceed the allowable load of household power sockets, fuses, meters and wires before use.
(2) When installing household appliances, pay attention to the use environment of the appliances. Do not install household appliances in damp, high temperature, dusty, flammable and corrosive environments.
(3) Kitchen, storeroom and other places that are easy to be affected with damp and corrode, always check for leakage. Generally, the test pen can be used to test on walls, floors and equipment shells.
(4) When using household appliances, the power cord should have a complete and reliable plug. It is not allowed to insert the wire directly into the socket. Don't use two-pin plugs and two-pin sockets instead of three-pin plugs and three-pin sockets, so as to avoid charging the metal shell of household appliances due to wrong plug connection and causing electric shock casualties.
(5) Electric heating equipment, such as electric heaters, electric stoves, electric heaters, electric showers, electric irons and soldering irons. The current is high and the heat is high, so everyone should switch on and off by themselves. It is forbidden to operate with plugs, and the socket capacity should meet the requirements.
(6) Switches and fuses are not allowed to be installed on the ground wire and zero wire. It is forbidden to connect the grounding wire to pipes such as tap water, gas and heating.
(7) When using household appliances, don't touch the switch and shell with wet hands. Use electric appliances such as hair dryer and soldering iron, and don't wind wires on your hands. When moving electrical appliances, cut off the power supply and don't pull the wires by hand.
(8) Don't pull wires or connect electrical equipment randomly, and don't use the method of "one line at a time" to connect electricity.
(9) When the insulation of the power cord of household appliances is damaged, it should be wrapped with insulating cloth, and it is forbidden to wrap it with medicinal tape such as Shangshi Zhitong Ointment.
(10) After using household appliances, cut off the power supply at any time. When it is necessary to cut off the power supply in case of sudden emergency, be sure to cut the wire with electrician tongs, and don't pull the wire by hand.
(1 1) Don't fly kites, shoot birds or install antennas near power lines, don't tie animals to poles and stay wires, and don't dig holes or borrow soil near poles and stay wires to prevent poles from breaking.
(12) In case of electrical equipment failure or leakage fire, immediately turn on the power switch, and do not use water or acid-base foam extinguisher to extinguish the fire before cutting off the power supply.
(13) Don't hang clothes on the wires to avoid electric leakage and electric shock due to damaged insulation.
(14) Don't go near the broken wire. 6 ~ 10 kV high-voltage lines should be at least 10m away from the conductor landing point, and timely report to relevant departments for emergency repair.
(15) Don't touch the lamp holder, switch and socket with wet hands. When replacing the light bulb, turn off the switch first, and then stand on the dry insulation. Don't pull the light wire too long or pull it around.
(16) If women find someone getting an electric shock, they should quickly cut off the power supply or connect wires with dry wooden sticks, bamboo poles and other insulators, so that the person who gets an electric shock can be separated from the power supply immediately. If the person who gets an electric shock is in a coma and stops breathing, he should be given artificial respiration immediately and sent to the hospital for rescue as soon as possible.
(17) When digging the ground, you must first contact the local power supply department, read the signs indicating the location of underground cables, and take reliable measures to prevent accidental injury to cables, causing casualties, power outages and other accidents.
(18) Do not pile combustible materials such as coal and other items near poles, substations, power distribution rooms and switch boxes in buildings to build houses. This poses a threat to the safe operation of equipment, and also brings difficulties to the maintenance and repair of electrical equipment, which affects the fire escape and causes hidden dangers.
(19) Don't arbitrarily post publicity materials on poles, distribution rooms and switch boxes in the building, so as not to block the operation signs and affect the emergency repair work.
(20) It is forbidden to climb poles, transformers, etc. It is forbidden to open the switch box door in the distribution room and the building without permission to avoid accidents.
(2 1) It is forbidden to lift (high) cars or set up scaffolding near overhead power lines.
(22) When household appliances or wires catch fire, before cutting off the power supply, it is forbidden to put out the fire with water to prevent electric shock accidents.
The second is to check the electricity of the household appliance shell.
The vast majority of household appliances use single-phase power supply, whether with motors, such as electric fans, hair dryers, refrigerators, etc. Or transformer or heating wire, such as TV, electric iron, incandescent lamp, etc. When in use, if the shell is not grounded, although there is no problem with its own insulation, its metal shell often appears "charged" phenomenon, which can make the test pen glow, but ordinary voltmeter can not measure it. At this time, you can carefully check and judge with a test pen.
(1) The power supply is AC and DC appliances or wires below 500 V. When the shell or skin is tested with a pencil under normal power-on, the neon light bulb will not emit light. When the insulation performance drops, leakage or damage occurs, breakdown occurs, and wiring errors occur due to some reasons, such as moisture, aging and damage of insulation, neon bulbs will glow. Its brightness is proportional to the measured voltage. The higher the voltage, the brighter the neon bubble.
(2) Method of distinguishing live wire from neutral wire: When testing 220/380V three-phase four-wire power supply line, the conductor to be tested that makes neon bulbs glow is live wire, and the conductor that does not glow is zero wire.
(3) Method for judging alternating current and DC: When testing alternating current, both ends of neon lamp bulb are lit; When testing direct current, only one end (negative end) is on.
