Core tip: the recently issued "the Ministry of industry and information technology on accelerating the transformation and upgrading of China's electrical appliance industry" mentioned that washing machines should develop fully automatic products with clean degree, good energy and water saving effect and low noise. What is the status quo of energy-saving technology and energy-saving products in China's washing machine industry? How to improve the product cleanliness performance? How will the frequency conversion washing machine market develop in the future? This topic mainly interprets and analyzes the product structure of mainstream enterprises from the above aspects, so as to promote the industrial upgrading of the whole industry.Energy saving and water saving technology becomes product competitivenessWith the prominent problem of product homogeneity and the increasingly fierce market competition, many home appliance manufacturers realize that only by establishing the core competitiveness on energy-saving and water-saving technologies and product development investment, can they seek market breakthroughs and realize the sustainable development of enterprises.Matsushita: limited precipitation and consumption reductionIdeas for life is a concept that Panasonic has been adhering to for a long time. Panasonic washing machine is also sparing no effort in energy conservation and emission reduction. It can provide consumers with comfortable life and reduce water consumption and power consumption. For example, wave wheel frequency conversion washing and drying machine, drum frequency conversion alpha series, drum frequency conversion three-dimensional washing series products all adopt frequency conversion direct drive motor, which greatly improves the precision and stability of motor in controlling washing and dehydration operation, so as to make ultra-low silent washing, low water level circulation, efficient water saving and large-scale power saving become possible.Siemens: always pay attention to energy conservation and environmental protectionSiemens electrical appliances has always been concerned about energy conservation and environmental protection, committed to the development of green technology and green products. In the second half of 2009, Siemens Home Appliances launched the 3D air condensing washing and drying machine. It uses Siemens 3D air condensation technology to condense the ubiquitous air, ending the traditional water condensation era. Each washing saves 30-90 liters of water than the traditional dryer, greatly improving the drying efficiency.Comprehensive enhancement of product cleaning performanceWashing ratio is an index to judge the washing effect of washing machine. Through consumer research, it is found that the washing ratio has always been ranked among the consumers who buy washing machines. Therefore, over the years, washing machine enterprises have been focusing on how to better improve the cleanliness of washing machines, and constantly create washing technologies to meet the needs of consumers for washing clothes.Aiming at the problem that clothes can not be thoroughly washed and washing powder in daily life, the Panasonic foam washing machine adds detergent to the special device foam generator, which makes the washing powder fully dissolved and quickly transforms into a micro foam washing liquid, which is wrapped in clothes, deep into the fiber and clean dirt. The national household electrical appliances quality supervision and inspection center provides the test report, the foam washing machine washing rate has increased by 40.Hisense Kelon, the main player in washoutHisense washing machines have made continuous breakthroughs in improving the washing performance of products. Hisense launched the rotary cube series wave wheel washing machine in 2010, which has three international leading technologies, namely, rotary cube non winding technology, three-dimensional three-dimensional water flow technology and rotary cube cleaning technology, to comprehensively improve the washing performance of washing machines.With the continuous improvement of people's living standards, drum washing machines have gradually become consumers.Noise reduction is a system engineeringThe silent design of washing machine is a system engineering, such as the coordination of waterway system, drive system, control system and vibration balance system. Because the washing machine not only uses electricity, but also needs water, it is difficult to achieve satisfactory mute effect only in a certain system. In addition to the configuration of variable frequency motor noise reduction, the optimization design of each system of the whole machine is also very important.Siemens: Night washing becomes a selling pointSiemens washing machine has been in the leading position in the industry in silent technology, and is committed to bring comfort and humanized use to consumers. In 1997, Siemens electric appliances first launched the silent washing machine, and its silent washing case was applied in China in 1998. Siemens Home Appliances launched the 3D positive and negative washing series washing machine in 2009. It has night washing function, which is suitable for washing cotton or chemical fiber fabrics. When washing, it presents low-noise operation mode, automatically turns off the program prompt sound, and creates a quiet sleep environment. It really brings quiet and quiet home environment for consumers. Even washing clothes at night will not affect family rest.Midea: optimizing product structure designThe vibration and noise of washing machine has always been one of the difficult problems in industry research, especially in drum washing machine. Midea series washing machine ensures the stable operation of washing machine by optimizing product structure design and adopting damping and mute equipment.Taking the 10 kg Beverly drum washing machine developed by cygnet and general motors of the United States as an example, this series of washing machines adopts advanced 6-point balance damping system and Emerson frequency conversion motor with high efficiency and energy saving, which can keep the product quiet operation no matter day or night.Frequency conversion products enter the fast lane of developmentThe application of frequency conversion technology and materials can make the enterprise develop rapidly with the rapid growth of the market. At present, frequency conversion washing machine is the representative of enterprise image. However, with the change of people's consumption concept and the development of the industry, the frequency conversion washing machine will be popularized rapidly.At present, the washing machine with frequency conversion technology is welcomed by consumers for its advantages of low noise, wide washing range and energy saving. It can be predicted that the washing machine industry will enter the background of technology competition...

　　Industrial washing machine often encountered a problem is: washing machine water is not smooth, there will be no water or water does not stop, when encountered these problems how to solve? We give the following solutions. 1. Check whether the drain valve of the industrial washing machine is blocked by dirt, which may cause the water inflow of the industrial washing machine is not smooth. Solution: clean the dirt inside the drain valve in time. 2. Check whether the computer board is damaged or aged. Solution: replace the new computer board or re adjust the computer program. When the washing machine does not water: check whether the water inlet valve filter screen is blocked and whether the water inlet valve is damaged? After confirming that they are in good condition, measure the voltage of 220 V at both ends of the solenoid valve with the AC voltage block of the multimeter, proving that the fault is in the solenoid valve itself. When measuring the resistance of solenoid valve coil with resistance block, the normal value should be 4.5 ~ 5.1k & and the measured resistance value is infinite, which indicates that the coil of solenoid valve is burnt out, replace the water inlet valve and remove the fault. Industrial washing machine water inflow: the water inflow of the washing machine has reached the rated water level, and the water inlet solenoid valve still does not stop. In this case, the water level pressure switch is damaged, which can be judged by blowing pressure method. Cut off the power supply; remove the water level switch, blow air to the pressure switch through the return pipe, and measure the resistance between the two terminals of the water level switch with a multimeter. When blowing, the resistance should tend to zero, and when not blowing, the resistance value should be greater than 10k & after inspection, the measured resistance value of the machine is always very large, and the action sound of the contact in the water level switch can not be heard, which indicates that the water level pressure switch is faulty. After replacing the water level pressure switch, the fault was eliminated. Fault location of drainage failure: drain valve is blocked; electromagnet coil is open circuit; program controller has no signal output. The above is what we give you to the industrial washing machine water is not unobstructed....

　　Some of the industrial washing machine motors used in the laundry room are burnt out. How can we avoid this situation? The following industrial washing machine manufacturers will talk about it for you. 1. First of all, we must ensure the cleanliness of the motor of the industrial washing machine. When the industrial washing machine is running, there should be no dust, water stains and other kinds of sundries within 3M around the air inlet of the motor. In this way, these impurities are inhaled into the motor of the industrial washing machine to form a short-circuit medium, which will damage the insulation layer of the wire in the motor, cause short circuit and burn the motor. 2. Do not overload the industrial washing machine. If the industrial washing machine is overloaded, the motor of the industrial washing machine will be overloaded and the voltage will be too low. If the motor overload time of the industrial washing machine is too long, the motor will absorb a lot of active power from the grid, so the motor current of the industrial washing machine will increase rapidly, and the temperature will also rise. The high temperature will aging the insulation layer of the motor and eventually burn the motor. 3. In order to ensure that the temperature of the motor of the industrial washing machine is in a reasonable range, for the motor bearing, stator and shell and other parts, whether there is abnormal temperature change, especially for the industrial washing machine motor without voltage, current and overload protection, it is very important to detect the temperature rise better. If the temperature rise of the industrial washing machine motor is too high, the motor will burn Destruction. 4. It is necessary to check whether the three-phase current of the motor of the industrial washing machine is balanced. Only when the difference between the current of any one phase and that of the other two phases does not exceed 10%, the motor of the industrial washing machine can operate in a safe direction without burning....

　　Injection of main steam is a very expensive method for heating water. The recovered condensed water is a valuable water resource in the laundry plant, because the water has been softened for steam generation, treated by chemotherapy, heated once, and then returned to the recovery tank at high temperature for reuse. When the high-temperature condensate is directly injected into the washing water for heating, it will be subject to additional treatment According to the Department of energy estimates, reducing or not using main steam heating can save nearly 18% of the fuel used to heat makeup water. At this time, the washing dragon operator will ask how to start with cold water? Or if the system stops for an hour in case of failure, how to heat the water? One way is to add heat recovery devices for each bin, so that hot water or even hot oil can be used to keep the temperature of the operating bin (without steam injection into the washing chamber), so as to reduce the need for central boiler. Another method is to add a small steam generator to provide steam for initial start-up and short-term temperature. In all cases, the actual production situation of the laundry plant will determine the scheme....

　　Electrical design of industrial washing machine: frequency conversion speed regulating industrial washing machine is selected, which not only saves energy, but also increases the speed of industrial washing machine in the rising process from washing to high-speed drying, and a section of uniform clothing distribution program is set to make the machine start smoothly without impact and prolong the service life of the machine. If the LCD graphic layout computer controller is used, the speed of the washing machine can be increased steadily, Can make the operation intuitive and convenient, and there is a 380V and 220V power supply can use the washing machine, so that you can avoid the trouble of finding out. Some washing machines use two speed motor as washing power. After each washing, the inner drum starts suddenly when it is about to dry, which makes the clothes unevenly distributed, resulting in severe vibration, big impact and short service life....

　　The protection function of frequency converter in automatic industrial washing machine? We all know that frequency conversion motor is used in automatic industrial washing machine, so why use frequency converter? Here are some functions of frequency converter in automatic industrial washing machine The protection function of frequency converter can be divided into the following two categories: (1) after detecting the abnormality, the control signal of power semiconductor device is blocked to make the motor stop automatically. (2) After the abnormal state is detected, corrective actions are automatically carried out, such as over-current stall prevention and regeneration overvoltage stall prevention. (3) Such as over-current cut-off, regeneration overvoltage cut-off, semiconductor cooling fan overheating and instantaneous power failure protection. The function of the protection circuit of the inverter is to judge the operation status of the inverter by detecting the output voltage, current and other parameters of the main circuit. When the current, voltage, temperature and other parameters are abnormal, in order to prevent the list of protection functions in the variable frequency speed regulation system, the protection functions of the frequency converter are as follows: 1 Instantaneous over-current protection: when the rectifier, inverter or load side of the inverter is short-circuit, and the current flowing through the rectifier and inverter switch device reaches the abnormal value (exceeding the allowable value), the instantaneous over-current protection action stops the operation of the frequency converter. Overload protection: when the output current of inverter exceeds the set value, and the current duration reaches the set time limit value, in order to prevent the switch device damage of inverter, overload protection action stops the operation of inverter. Overload protection has inverse time characteristic, usually using relay or electronic thermal protection (composed of electronic circuit). 3. Regeneration overvoltage protection: when the motor of the variable frequency speed regulation system is rapidly decelerating, the DC circuit voltage of the frequency converter will rise due to the feedback of the system regenerative power, and sometimes it will exceed the allowable value of the voltage and damage the electronic devices in the frequency converter. In order to suppress the regeneration overvoltage, the method of stopping the inverter or limiting the fast deceleration is adopted to realize the over-voltage protection of the system. Instantaneous power failure protection: for the instantaneous power failure within a few milliseconds, the inverter control circuit can work normally. However, if the instantaneous power failure is more than tens of MS, the control circuit will not work normally and the main circuit will lose power. In order to avoid the electrical or mechanical failure or accident caused by the misoperation of frequency conversion speed regulation system caused by instantaneous power failure, the frequency conversion and speed regulation system is equipped with instantaneous power failure protection to stop the operation of the inverter after the instantaneous power failure. Grounding over-current protection: when the load of frequency conversion speed regulation system is grounded, the grounding over-current protection function is set to protect the inverter of frequency converter. However, in order to ensure personal safety, leakage circuit breaker should be installed. 6 temperature abnormal protection: for the inverter with cooling fan, when the fan is abnormal, the temperature inside the frequency converter will rise, and the inverter will be damaged due to temperature overrun. Therefore, the cooling fan motor of frequency converter should be protected by thermal relay, and the heat sink of inverter switch device should be equipped with temperature sensor, and the inverter of inverter should be stopped after abnormal temperature is detected. The load protection functions of frequency converter are as follows: overload protection: the overload detection unit and inverter overload protection share the same industrial washing machine, but considering the overheat of the motor in the variable frequency speed regulation system at low speed, the temperature sensor is embedded in the winding of the asynchronous motor, or the electronic thermal protection installed in the inverter is used to detect the overheating of the motor. When the motor overload protection action is frequent, we can consider reducing the motor load, increasing the capacity of the motor and frequency converter. Over (over speed) protection: when the output frequency of the frequency converter or the speed of the asynchronous motor of the variable frequency speed regulation system exceeds the specified value, the over (over speed) protection acts to stop the operation of the frequency converter. The other protection functions of frequency converter are as follows: preventing stall over-current: when the frequency conversion speed regulating system is accelerating rapidly, if the asynchronous electric tracking is slow, the over-current protection circuit will act and the motor can not continue to run. Therefore, before the load current is reduced, it is necessary to control the speed of frequency rise or frequency decrease. The same control is sometimes applied to the over-current in constant speed operation. Prevention of stall regeneration overvoltage: the regenerative energy generated by the variable frequency speed regulation system during deceleration causes the DC voltage of the main circuit to rise. In order to prevent the protection action of the regeneration overvoltage circuit, the control should be carried out before the DC voltage rises to suppress the speed of frequency drop and prevent the speed control system from stalling. Instantaneous voltage loss or undervoltage of power supply: when instantaneous voltage loss or undervoltage occurs, the frequency converter will be able to maintain continuous operation. Some frequency converters can also track the motor speed and adjust the output frequency when the power supply voltage is restored. Automatic industrial washing machine, microprocessor abnormal protection....

　　As for the washing process of industrial washing machine, the washing process of industrial washing machine is roughly the same as that of our ordinary household washing machine. After washing, rinse and drain the water. But in the completion of these steps, time allocation is not the same, if it is done manually, it may be controlled by four buttons. If it is done automatically, then it is controlled by a control panel, and the time of each step is preset in the program, which can save time. There is no need to guard a person next to the laundry. Industrial washing machines are suitable for a wide range of places, such as factories, schools and other densely populated areas. Even families with more family members also use industrial washing machines. There is also a group called dry cleaners. Now we have large dry cleaners using washing equipment all over the country. It is also a good project to start a business....

　　First of all, the quality performance of an industrial washing machine directly determines its working performance and service life. Often the same price we should choose better quality performance. As for the quality performance, it depends on the material selection and production process. For the material selection, we can compare the material selection and the selection of such core components as frequency converter, bearing and motor. For the production process, we have to look at its production technology application, production equipment application, as well as the assembly process and details processing. For the comparison of materials, it is still simple, we only need to ask one by one, and for the production process, we have to look at the manufacturer on the spot, or after seeing the actual machine, we can make the actual comparison. The second is price. Although there is no good product and good product is not cheap, most users still hope to purchase industrial washing machines with limited budget. For the comparison of the prices of industrial washing machines, we may as well do this. First, we should find out which grades and prices of industrial washing machines are available in the market. Then, according to our own budget, we can choose industrial washing machines of a certain grade and price. Finally, we can compare the manufacturers of industrial washing machines at this price and grade. For example, if you have sufficient capital budget and want to buy imported industrial washing machines with high prices, you can first list the manufacturers of imported industrial washing machines in the current market, and then compare them with specific manufacturers. For example, if you can only buy domestic general brands of industrial washing machines in your budget, you can list the manufacturers of this grade, and then compare them one by one, and decide whether to choose Jiangsu, Shanghai, or Guangdong industrial washing machine manufacturers for cooperation. After that is the comparison of after-sales service. The time limit and scope of after-sales service is particularly important for consumers. The time limit determines the length of service you enjoy, and the scope determines the service range (warranty scope) you can enjoy. For example, some industrial washing machine manufacturers provide 3-Pack 1-year service, or some manufacturers provide 3-Pack service with only core components. Seemingly small gap, but for our consumers, the role it can play is larger. Therefore, more often, when we choose manufacturers of industrial washing machines, we should choose the ones with longer after-sales service time limit and wider scope. Moreover, we should also pay attention to whether they have the ability to ensure the timeliness and effectiveness of after-sales service. Therefore, the comparison of industrial washing machine manufacturers is not a certain aspect, but should be comprehensive. It is very important for you, so we expect all users to take it seriously. As a professional manufacturer of industrial washing machines, we wholesale a full range of industrial washing machine manufacturers with good quality, good performance, suitable price and high cost performance. We enjoy 3 packs of the whole machine for 1 year and lifelong tracking service. We are looking forward to cooperating with you!...
