In recent years, with the continuous advancement of washing machine washing technology, people are pursuing washing and cleaning, and in order to avoid cross-contamination between clothes, the demand for sorting and washing is increasing. At the same time, with the improvement of home life, people have room for indoor space. The requirements for utilization and aesthetic layout of the room are also constantly increasing. Together, these factors have contributed to the rapid development of wall-mounted washing machine products.
The emergence of wall-mounted washing machines has broken people's consistent perception of "washing machine = standing vertical". From a technical point of view, the wall-mounted type is a completely new structure for the washing machine. What followed was the consumer's doubts about this new product: the washing machine is heavy, will it be unsafe to hang up? Will it cause large vibrations to damage the wall and cause safety hazards? To answer these questions On January 24, 2018, sponsored by China Household Electrical Appliances Research Institute, China Household Electrical Appliances Research Institute Institute of Testing and Measurement Technology, China Household Electrical Appliances Research Institute Health Appliance Analysis and Testing Center hosted the "wall-washing vibration worry-free" wall-mounted Washing Machine Vibration Performance Technology Seminar and Technician Club Innovation Forum was held in Beijing.
meeting venue
The forum was hosted by Yue Jingsong, director of the Washing Performance Laboratory of the China Household Electrical Appliances Research Institute. He said that a healthy life is inseparable from a comfortable and undisturbed home environment. However, if the design of the wall-mounted washing machine is unreasonable or the installation is not in place, there may be a major safety hazard. In fact, if the structural design is reasonable, the product is fixed and reliable, and the wall-mounted washing machine can achieve less vibration and better stability than the vibration problem that cannot be avoided in the operation of the traditional standing washing machine product.
Wall-mounted washing machine is a new trend of healthy washing
Lu Jianguo, director of the Institute of Testing and Measurement Technology of China Household Electrical Appliances Research Institute, said at the forum that with the development of society, people's demand for washing is no longer just to wash away stains, but also increase the demand for health, different family members. The clothes are washed separately, and the mother and baby clothes can be washed separately and in time. The wall-mounted washing machine has a small footprint and can be used in a small space. It is convenient to be used as a second washing machine in the home. It can realize the characteristics of classified washing, small washing and timely washing, and will become a new trend of future healthy washing products.
Director Lu Jianguo speaks at the forum
Wang Bo, head of the washing performance of Little Swan Research Institute, reported on the development of Little Swan's health care products at the forum. Health care will be the trend of the future, the needs of consumers urgently concerned. They use the wrinkles, deformations and damages of the clothes in the washing machine from the consumers. There is bacteria in the barrel of the washing machine. Some stubborn stains and stains cannot be completely removed. The bacteria carried on the clothes cannot be completely removed. The small pieces of clothes are very expensive and costly. Starting from the pain point of machine noise and vibration, the company developed and applied three technologies: water cube water flow technology, nano silver base sterilization technology and cold water washing technology.
The water cube water flow technology breaks through a single beat and wash, and simulates various washing modes on the washing machine through the bionic design.æ‰æ“Water flow: running at low speed, with magic lifting ribs, rubbing and rubbing, disintegrating surface stains, and caring for clothes. Penetrating water flow: running at medium and high speeds, the water flows from the inside out, deep into the fibers, and washes deep stains. Pengbai water flow: high-speed operation, vigorously flushing and squeezing clothes, and quickly improve the washing effect.
The nano-silver-based protective clothing technology continuously releases nano-ions during the washing process, effectively sterilizing bacteria, inhibiting bacteria, and achieving clean and sterile storage under cold water conditions. Including long-acting slow-release technology: nano-silver ions are embedded in the crystal network structure, and the nano-silver ions can be slowly released after water to ensure long-lasting sterilization, and the sustained-release time is up to 60,000 hours; precise release technology: nano-silver ion The release amount is maintained at 0.002mg/L, while ensuring safety (the drinking water standard is 0.05mg/L), the sterilization effect is obvious (the silver ion concentration reaches 2 x10-12mg/L, it can kill most bacteria); Bacteriostatic technology: Nano silver ions can be retained continuously to ensure long-lasting antibacterial effect after washing, and the antibacterial effect lasts for 48 hours.
Cold water washing technology, because the fading situation increases with the increase of water temperature, cold water washing is beneficial to reduce the fading of clothing. Under the action of the water cube, the fat and protein in the stain are removed, and the deep stains of the fiber migrate to the surface. Achieve the function of stain removal.
Through the application of the above three technologies, Little Swan realized that the wall-mounted washing machine can effectively remove bacteria in the whole washing space under low temperature conditions, care for clothes, wash for a long time, remove bacteria, disinfect the inside and outside barrels, antibacterial and safe after washing. The detection (silver ion content) and the like were all tested, and the decolorization deformation rate was compared with the conventional hot water condition, the decolorization was reduced by 39%, and the laundry deformation was decreased by 45%.
Little Swan Wall Mounting Washer
Wall cleaning and vibration worry
According to the forum, the vibration performance test method in the current washing machine performance test standard is not fully applicable to wall-mounted washing machine products. In response to consumers' doubts about the installation stability of the wall-mounted washing machine products and the vibration intensity in use, in order to fill the gaps in the industry technology and better evaluate new products, the Institute of Testing and Measurement Technology of China Household Electrical Appliances Research Institute and Little Swan Shares Co., Ltd. has formulated the Standard for Clean Technology of China Household Electrical Appliances Research Institute, "Test Method for Vibration Performance of Wall-mounted Drum Washing Machine". This standard can effectively evaluate the stability of wall-mounted washing machine products through scientific and reasonable testing methods. This forum will discuss the content of the "Test Method for Vibration Performance of Wall-mounted Drum Washing Machine" (hereinafter referred to as "Test Method") and the test method of the product, and analyze the relevant key indicators to help consumers understand the "Test Method". Open up many doubts about the purchase and use of wall-mounted washing machine products.
Liang Zhiyong, laboratory engineer of washing performance of China Household Electrical Appliances Research Institute, said that the standards for the "Test Method for Vibration Performance of Wall-mounted Drum Washing Machines" include GB/T 4288-2008 electric washing machines for household and similar purposes and GB/T 4214.4-2008 And special purpose electrical noise test methods for washing machines and centrifugal dewatering machines. The washing machine involved is fixed on the wall by anchor bolts or other means, and has no suspension system. The wall support supports the unbalanced transmission force of the whole machine, and the laundry is placed in the drum and partially immersed in water. A washing machine that performs washing by means of continuous rotation of the drum or timing of rotation in the forward and reverse directions. The wall-mounted drum washing machine mainly tests the dehydration stage. When the main washing process is finished, the single-drinking program is selected (adjust the maximum speed), and the vibration of 2 Hz to 200 Hz (FFT, CPB, vibration amount) of the single dehydration program is recorded. Record once and use the tachometer to test if the highest dehydration speed can be achieved. This time, commissioned by Wuxi Little Swan Co., Ltd., the TG30-DSN1 drum washing machine produced by the company was tested and tested.
Xiong Ming introduces wall-mounted washing machine
Xiong Ming, head of the Institute of Intelligent Technology at Little Swan Research Institute, introduced the development process of wall-mounted washing machine products. He said that with the increase of migrant population and the independent living of young people after marriage, the proportion of small households is high and increasing. At present, the size of households in the country has been shrinking, which is already lower than 3.1. Small-sized households will further increase the demand for small-sized washing, underwear washing and quick washing. In addition, due to the impact of the third birth peak, a large number of infant and family families will have greater demand for children's washing, clothing sterilization and other functions. The survey organization Nielsen questionnaire survey 1200 households collected 80 user samples, covering 8 cities and rural areas in most parts of the country, the results show: appearance, space occupation, vibration noise, sterilization, classification washing is the user's most concerned factors, accounting for The ratio is as high as 61%.
Based on this, Little Swan created the first embedded wall-mounted washing machine in China, and the embedded installation made the product as space-saving as possible. This product uses the unique water cube washing program technology, energy efficiency level up to 2 levels. Each use can save 9L of water, can save 0.12kwh, a family uses 200 times a year, can save 1.8 tons of water, saving 24kwh. The product is rigidly fixed to the wall by 4 expansion bolts, and the vibration during operation is very small (the vibration amount of the high-speed dehydration operation period is <0.1mm). With BLDC motors, washing noise can be as low as 48db and dehydration noise can be as low as 64db. The 3D vibration detection function is configured to detect the smoothness of the washing machine during operation. When the machine is too large due to the wrong installation mode, an emergency alarm will be issued and the user will be prompted to contact the after-sales for maintenance.
A through-bore slip ring is an electrical device that allows current to pass between two points in a rotating assembly without a physical connection. There is no break in the circuit. This is accomplished by passing the current through a rotating brush that contacts a stationary metal ring. The metal ring is mounted on the shaft of the assembly and provides a continuous path for the current.
It is an integrated circuit component that consists of two conducting rings that are separated by a gap or spacer. When the rings are brought into contact, current can flow between them and produce a rotational motion. Slip rings are used in various applications where high efficiency and low power consumption are essential, such as communication systems, motor control systems, and energy harvesting devices.
The through-bore design allows for rotation of the assembly while transmitting power or data. They are often used in applications where there is a need to rotate an object while keeping a power or data connection open, such as on a wind turbine or radar antenna.
The Oubaibo's through-bore slip ring is a newly designed product that has many advantages over other products on the market. It is small and lightweight, making it easy to install and use. The through-bore design also allows for a high degree of flexibility, making it ideal for use in difficult or tight spaces. Additionally, the Oubaibo through-bore slip ring is very efficient, providing a high degree of power transfer with minimal loss.
