First of all, you should choose a rice cooker with the right power. Practice has proved that 1 kg rice, 500 watt rice cooker, boiled for 30 minutes, consumes 0.25 degrees of electricity. It takes about 20 minutes to use a 700-watt rice cooker, and the power consumption is only 0.23 kWh. High-power rice cooker saves time and electricity.
Secondly, if there are stains on the surface of the electric heating plate and the bottom of the pot, they should be wiped clean or polished gently with fine sandpaper to avoid affecting the induction efficiency and wasting electricity.
Third, when using electric cookers, it is best to wash rice in advance and cook with boiling water, and the water consumption for cooking should just reach the standard of dry rice. Unplug the plug immediately after cooking, otherwise when the temperature in the pot drops below 70℃, it will automatically be powered on intermittently, which will not only consume electricity, but also shorten the service life of the rice cooker. When cooking with an electric cooker, covering it with a towel can reduce heat loss.
In addition, when cooking, the power can be turned off for 7-8 minutes after the water is boiled, so that the waste heat of the rice cooker can be fully utilized and the purpose of saving electricity can be achieved.
2. Save the skill of washing clothes
Selected cleaning program
When the washing machine washes a small amount of clothes, the water level is set too high, and the clothes float around in the high water, lacking friction with each other, but not clean and wasting water. At present, in the program control of washing machines, washing machine manufacturers have developed more washing machines with water level, the water level is refined, and the washing start-up water level is also reduced by1/2; The washing function can be set as primary cleaning, secondary cleaning or tertiary cleaning, and we can completely choose different washing levels and washing times according to different needs, thus achieving the purpose of saving water.
Soak in advance to reduce water consumption
The washing time can be determined by the fabric type and the degree of dirt of the clothes. Soaking clothes before washing can reduce rinsing times and water consumption.
Proper amount of washing powder
The dosage of washing powder (that is, the concentration of washing powder in water when the washing machine is at an appropriate water level) should be mastered well, which is the key to the rinsing process and the key to saving water and electricity. Take a washing machine with a rated laundry capacity of 2kg as an example. Low-level low foaming detergent needs about 40g when the laundry amount is small, and 50g when the water level is high. According to the dosage, the optimum washing concentration is 0. 1% ~ 0.3%, so the solution with this concentration has the greatest surface activity and good decontamination effect. There are many kinds of washing powder in the market with different functions, which can be selected according to family habits. Too much washing powder will inevitably increase the difficulty and frequency of rinsing.
Wash clothes together
Don't wash clothes too little. It is also a water-saving method to concentrate on washing after waiting too much.
Make full use of flushing
(1) Increase the number of rinsing times, and the amount of rinsing water per time shall be based on the basic submerged clothes, and shall not exceed. (2) The water consumption for each rinse is the same. (3) After each rinse, wring out the clothes as much as possible, and then drain the water. (4) If the rinsed water is left to the next batch of washing water, 30-40 liters of clean water can be saved at a time.
3. Save our bath water
Take a shower with a shower head:
Taking a shower with a shower head saves as much as 80% water as taking a bath with a bathtub. So I suggest you take more baths, less baths or no baths.
(1) Learn to adjust the ratio of hot and cold water.
(2) Avoid taking a shower for a long time when taking a bath, and turn off the water in time when scrubbing; Don't leave the water in the sprinkler on all the time, let alone turn it on.
(3) Try to get wet from head to toe, then wipe the whole body with soap and rinse it for the last time. Don't wash your hair, upper body, lower body and feet alone.
(4) Take a bath with concentration, hurry up, don't be idle, or wash while chatting. Don't have a big water fight with your good friends in the bathroom. Remember: time is water!
(5) Don't take the opportunity of taking a bath to "wash clothes and shoes by the way".
Take a bath in the bathtub. Pay attention: don't fill it with water. 1/3- 1/4 pots are enough.
The water after bathing can be used for many purposes, such as flushing toilets and mopping floors.
Four other household water-saving tips:
What if the toilet leaks?
The common cause of toilet water leakage is that the hemispherical rubber cover covering the drain is light, and the water tank leaks due to insufficient gravity when falling, so it often needs to be closed repeatedly. The solution is to tie several heavy objects, such as big nuts and toothpaste tubes, on the connecting rod connecting the rubber sleeve, and pay attention to tie them as close as possible to the rubber sleeve, so that it is easier for the rubber sleeve to cover the drainage hole tightly and the water leakage problem is solved.
Adopt water-saving appliances
Conditional families should replace water-saving sanitary ware. It is suggested that you install and use water-saving sanitary ware or sanitary ware, use ceramic tiles to seal the water nozzle, eliminate the spiral lifting hot metal nozzle, transform the toilet water tank above 9 liters, and use the toilet water tank below 6 liters. For the existing non-water-saving toilets in use, we can minimize the flushing water by placing a brick and a salt water bottle in the water tank.
domestic consumption
Use domestic water in series as much as possible. For example, rice washing water can be used to wash vegetables and help remove pesticides from the surface of vegetables. Vegetable washing water can also be used to flush toilets. Bath water, laundry water and foot washing water can be used to mop the floor and flush the toilet.
Advocate one meter per household to reduce the leakage rate of pipe network behind the meter.
In areas with high water pressure, residents may wish to control the water pressure by adjusting the tap water valve, which can save considerable water.
Don't turn on the tap for a long time to wash hands, clothes or vegetables. When washing vegetables and fruits, we should control the flow of the faucet and change the constant water washing into intermittent washing.
Repair dripping faucets and other water appliances in time. The dripping faucet can consume 70 liters of water every day. It is suggested that using water-saving appliances can effectively save water.
Five other tips for saving electricity
Energy-saving lamps save electricity by 75% compared with ordinary incandescent lamps.
The sleep function of air conditioner can save energy by 20%.
Reduce the number of refrigerator door switches! Shorten each opening time.
The louder the TV volume, the greater the power consumption.
