What are the small inventions of saving water and electricity?

1, TV When you use TV, whether it is a color TV or a black-and-white TV, the brightness should not be too bright, and the volume should be as low as possible without affecting the audio and video. In addition, do not switch frequently. For some remote-controlled color TVs without AC shutdown function, the remote-controlled receiving part is still charging after shutdown, and the indicator light is on, which will consume some electricity. Unplug the power plug after shutdown.

2. The power amplifier saves electricity mainly by reducing the volume, and the impedance of the external speaker should not be too small. Avoid the combined use of multiple speakers, reduce the load of the power amplifier as much as possible, and achieve the purpose of saving electricity and protecting the machine.

3. Pay attention to the refrigerator, and don't push the food in the refrigerator too full or too dense, otherwise it will hinder the circulation of cold air and cause the refrigerator not to cool. There shouldn't be too little food in the refrigerator. If there is too little food in the refrigerator, it will lose air conditioning and waste electricity. Refrigerators should minimize the number and time of opening doors, and defrost in time except frost-free refrigerators. Pay special attention to dust the condenser regularly, so as not to affect the refrigeration effect and waste electricity.

4, washing machine clothes as much as possible. The clothes washed in the washing drum should be close to the maximum laundry amount, so as to reduce the throwing times and improve the work efficiency. If the washing machine has been used for more than 3 years, it is found that the washing is weak, and the motor belt of the washing machine should be replaced or adjusted to make it moderately tight. Lubricating oil should be added to the place where the washing machine needs to be oiled every once in a while to ensure good operation and achieve the purpose of saving electricity.

5. rice cooker rice cooker is a kind of rice cooker with high power consumption. Because of its excellent heat preservation performance, when cooking food in an electric rice cooker, when the water in the cooker boils, the power supply can be cut off and the waste heat can be used for heating for a period of time. If the rice is not cooked, you can turn on the power again. In this way, intermittent power supply can save electricity by about 20% to 30%.

6. Electric iron When using an electric iron, clothes should be ironed as intensively as possible, and the corresponding temperature control points should be selected according to different materials. If you use an ordinary electric iron that can't adjust the temperature, you should also master the temperature and cut off the power supply immediately when you reach the temperature required by the cloth. If thermal insulation is needed, a 3-amp, 400-volt rectifier diode can be connected in parallel at the switch, and it will heat normally when the switch is turned on; When the switch is turned off, the rectifier diode is connected in series with the circuit and enters the heat preservation state. The electric iron can save about 40% electricity in the heat preservation state.

7. The power consumption of the electric fan motor is directly proportional to the load (that is, the blade size of the electric fan) and the voltage applied by the motor, and the voltage applied by the motor is directly proportional to the rotating speed. In other words, the larger the blade diameter, the higher the rotational speed and the greater the power consumption. Under the condition of basically meeting the air volume, try to choose an electric fan with smaller blade diameter. The electric fan should start at high speed, and then switch to medium speed or low speed after reaching the rated speed, which is beneficial to the speed start of the motor, thus achieving the purpose of saving electricity and protecting the motor.

8. For household lighting, try to use energy-saving lamps with high brightness and low power. At present, the energy-saving lamps promoted generally can save electricity by about 20% to 70%. However, we must use qualified high-quality energy-saving lamps produced by regular manufacturers, and we must not be greedy and cheap, so as not to cause unnecessary losses to ourselves. Existing incandescent lamps in the home (including chandeliers, wall lamps, ever-burning lamps, etc.). ). If high brightness is not needed, rectifier diode (1 amp, 400 volts is lower than 100 watts; 100W, 300W, choose 2 amps, 400V), which can save about 40% electricity.
