Along with the development of science and technology, more and more new technology has been applied to the field of design and manufacture of washing machines. The current frequency is the hottest technology and direct drive technology.

     In today's high-speed economic development, energy shortage has become a constraint to the economic development of a major problem, as excessive energy consumption is also leading to environmental degradation countries in the world face a serious problem.

     In response to this situation, China's relevant departments to guide consumers to buy higher levels of energy efficiency appliances, and promote the development of energy-saving products, in 2005 began to gradually products for a wide range of household electrical appliances energy efficiency labelling system whereby the sales in China such products must carry the energy efficiency labelling. As a very high share of the family home appliances, household electrical products in the washing machine on March 1, 2007 implementation of the energy efficiency labelling regime.

     For energy efficiency labelling system, individual enterprises各显神通washing machines, introduced many innovative design, to develop more energy efficient products, to gain an advantage in the market.

     Energy-saving motors are key components

     Complete machine energy, the most direct and effective method is the use of highly efficient components, in particular the key parts. The washing machine products, the motor is undoubtedly the most crucial components. Choice of a high-efficiency motors on the efficiency of the complete machine will play a vital role. Faced with international metal prices rising, some lawless parts manufacturers in order to save costs, the use of poor quality of enameled wire, silicon steel and other raw materials, leading to motor and reducing efficiency. This is a great waste of national resources, the majority of washing machine production enterprises should unite to resist this approach, a positive response to the call of national energy saving and environmental protection, and use some of the high efficiency motor. In addition, the choice of efficient drainage pump or valve components will also improve the efficiency of the components are play a role.

     Heating tube should be matched with the complete machine

     Mentioned above can be used in high-efficiency washing machine motor to improve energy efficiency, then, is not efficient use of energy-saving motors will be on? Obviously not, it is also necessary to motor and the minimum reasonable match. Because the motor is a very special product, the output power can be loaded with changes in a certain range change. In the process of change, the efficiency value is not fixed, at some point the maximum. In the complete machine design, as far as possible, should be rated washing machines in the state of design in the vicinity of the highest efficiency.

     The drum washing machines, heating energy consumption is the largest component, under normal circumstances, for washing water heating energy consumption accounted for the entire process of washing power consumption 70% to 85%. The heating pipe is basically a purely resistive components, not much below the efficiency, power factor (useful work and the ratio of total power) are close to 100%. Therefore, the heating tubes, energy-saving the crux of the matter is how to better match with the complete machine. On the same drum washing machines, if the choice of heating power of smaller, long heating wash water can be heated to the required temperature; larger selection of the heating power of the short heating can also wash water heated to the required temperature, the power consumption should be the same, so what better way? Obvious it is the latter.

     Longer because the former heating, water heating may be just the required temperature, washing the end of the process, hot water will be discharged directly, go to wasted. The time will be heated to the required temperature of the water, so that clothing can be a long time in high temperature washing water washing, more conducive to removing stains. Because of the increase of temperature can increase the solubility of detergent so that the movement of the dirt faster and weaken the dirt molecules and light fastness of the fabric. Thus, the dirt in the role of surfactant can be under more easily removed from the fabric.

     But not blindly pursue high-power heating pipe, first, prone to excessive power of potential safety problems, and the current distribution in the family has also limited the number of washing powder is due to the current contained in a variety of enzyme, the activity of all kinds the highest temperature not the same, if the temperature rises too fast, we can not give full play to a certain enzyme activity may result in removal of the effect of certain stains worse.

     Therefore, it should be a scientific and rational choice of heating, and washing machines to achieve the best match results.

     Water must select appropriate

     Wash water heating energy consumption on the impact of the most important factors is washing water, because heating wash water needs of the heat Q = C m △ t, m refers to the quality of water washing. Therefore, a reasonable design washing water, avoid excessive heating of water caused by energy waste, and can be played directly on the washing machine to reduce the role of energy consumption.

     In addition, the drum type washing machines, the test to join washing detergent rated capacity of its 1.0%, the concentration of detergent wash water entirely by the decision. Less washing water will increase the concentration of detergent, washing machines will naturally increase the decontamination capability. However, the washing water was also decided to wash the dirt under the concentration of too much concentration of dirt will cause their washing liquid suspension in the ability to reduce, re-deposition of larger trends. If the extent of sediment decontamination than the ability, it may also lead to the deterioration washing effect. Therefore, the water must be properly selected, it is necessary to energy saving, but also achieve good results Wash.

     Rational use of immersion time

     At present, many enterprises in the washing process with a certain amount of soaking time for the effective detergent and chemical composition of the stains in clothing full role in order to achieve the purpose of improving wash effect, but also can reduce the operation time Beilun played the effect of energy conservation. The experiments show that, simply wash over the immersion on the enhancement of the role is very limited. Now a lot of enterprises to the concept of the immersion movement, through rational design Beilun rotation and soaking time will be washed and soaked together with the wash than the increase will play a better result.

     Appropriate selection of spray rinsing way

     The wave wheel washing machines, GB12021.4-2004 standards set out in the classification indexes harsh, in order to achieve an energy efficiency rating is very difficult. Now more than washing machine manufacturing enterprises in the pursuit of this target, at "risk" by spray rinsing way. The so-called spray rinsing, washing in the end, the first rinse, do not use the rinse water to fill; but at the side of rinsing water spray, but also intermittently for dehydration and drainage. This could reduce the washing machine rinse water, but also reduced in the process of rinsing motor running time, to the purpose of energy saving. It is, however, there is a greater risk that GB12021.4-2004 not only provides standard than wash, power consumption, water consumption of these three energy efficiency label to express targets, but also provides the washing machine performance and dehydration Rinse GB/T4288-2003 performance must be consistent with the requirements of the standard. If one failed, even measured the energy efficiency rating for one do not have any significance.

     Spray rinsing by the way is likely to result in performance rinsing project failed, and is bound to have a certain impact on performance Wash. Therefore, this method must be used Washing machine capacitor  with caution, it is necessary to fully test verification through the rear can be no problem.

     Frequency and direct help to drive energy-saving technology

     The use of variable frequency motor characteristics is the largest energy-saving washing machines. Under normal circumstances, the use of the washing machine motor is a single-motor capacitor, by principle, the structure and manufacturing process constraints, the motor is only about 40% efficiency, but also high-efficiency 50% and variable frequency motor efficiency more than 80 per cent of the energy will play Washing machine capacitor  a natural effect. In addition, there are washing machines wash is high frequency, low noise, vibration, the advantages of small, relatively consistent with the current green design principles.

     Direct drive technology is used to speed the direct drive brushless DC motor cylinder washing or scrubbing dehydration technology. And the traditional washing machine motor washing through the skin between the cones bring Drive, the middle will have mechanical wear due to the loss of efficiency, direct drive technology is eliminating this intermediate links, coupled with the efficiency brushless DC motor itself much higher Washing machine capacitor  than on ordinary single-phase induction motor, therefore greatly enhance the overall efficiency.
