Artificial intelligence application speedup | Small household appliances intelligence has become an inevitable trend

On October 29-31, the 2018 China Household Appliance Technology Conference hosted by the China Household Electrical Appliances Association was held in Ningbo. During the period, the small appliance professional technology branch that first appeared at the technical conference was also held on the 31st. From Bo Xihua, Midea, Wanhe, Panasonic, Samsung, technical experts from China Household Electrical Appliances Research Institute and everyone shared their latest achievements in the technological innovation of small appliances such as dehumidifiers, mixers, humidifiers, vacuum cleaners and so on.

With the rapid development of technologies such as IoT technology, big data, cloud computing and artificial intelligence, the intelligentization of home appliances has become an inevitable trend. For small household appliances enterprises, intelligentization is once from technology research and development, product upgrade to user service, and channels. The systematic revolution of layout. The innovation of intelligent technology has also improved the performance and quality of small household appliances, creating new market demands.

Of course, because the current level of intelligentization of home appliances is generally not high and the problems of household appliances between different manufacturers are still difficult to interconnect, the future of home interconnection is full of uncertainty. At the meeting, Bo Xihua Electric (Jiangsu) Co., Ltd. software Engineer Zheng Haoran gave a keynote speech on the current status and future trends of smart home interconnection. He pointed out that many home appliance companies are now concentrating on the layout of smart home products. The further development of Internet of Things technology has made the interconnection of home appliances more Simple. Nowadays people are integrating technologies such as speech recognition and image recognition into new home scenes. Therefore, enterprises need to intelligently analyze user scenarios by applying artificial intelligence and other technologies to further provide convenience for users.

For the problem of intelligent development of home appliances, Panasonic has carried out an all-round exploration in the century-old home appliance industry. At the meeting, Bao Jianke, the head of Panasonic's home appliance research and development (Hangzhou), shared the keynote speech on the development of healthy food service based on smart home appliances. All products sold by Panasonic are closely connected with the customer management server (Big Data). Through cloud, APP, product group and life line connection, based on the design concept of 'health? taste', solve user's troubles and create consumption. The lifestyle that people yearn for. Taking Matsushita's light kitchen as an example, Panasonic proposed the concept of kitchen space service. To this, Bao Jianke explained that Panasonic wants to provide users with a space that can easily be delicious and promote health and beauty. Of course this Everything needs to be achieved through the IoT of Panasonic products.

It can be seen that the convenience and experience brought by intelligent people is unprecedented. These new elements give the product a higher level of development and advancement.

In addition to intelligence, the noise problem of small appliances has attracted the attention of most companies.

In the keynote speech of "Study on Stirring Noise of High Speed ​​Mixer", Wang Yue, a pioneering research engineer at the Academia Sinica, pointed out that at present, stirring noise, wind noise and vibration noise may become the main noise sources. Therefore, the noise reduction design and product performance are Mutual influence and control. At present, by optimizing the design of the serrated surface area, the sawtooth blade shaft can improve the noise. In the future, the company will further study the noise reduction scheme through multiphase flow and airline simulation. Ningbo Deye Daily Electric Technology Co., Ltd. Dehumidifier Development Department Director Feng Jinming shared the exploration and innovation of mute energy-saving technology for household dehumidifiers. According to Feng Jinming, the company has developed a strong forward centrifugal vane with low noise, high static pressure coefficient and low static pressure loss, and a small eddy volute The air duct minimizes the noise of the dehumidifier and raises the standard requirements of the noise level of the whole machine. The product noise index is much higher than the national standard.

Nowadays, small household electrical appliance enterprises are using new materials and new technologies are constantly being optimized.

Qian Chengcun, a senior engineer at Suzhou Samsung Electronics Co., Ltd., shared a “CFD simulation-based HEPA filter structure optimization method for air purifiers”. He introduced in detail that compared to the airborne blasting materials used for air filters, For fine glass fiber paper, EPTFE film and electrospun nanofiber mesh, the polarized polypropylene meltblown web has lower static pressure difference and higher dust collection under the same HEPA filtration requirements. It has great advantages for improving the amount of clean air and cumulative purification. Zhang Jiaming, business development manager of Connaught Asia Pacific, shared the "Low-pressure injection molding process to help intelligent performance of household appliances", the low-pressure injection molding process is a very low The injection molding pressure injects the hot melt adhesive material into the mold and rapidly solidifies the molding process (1-50 seconds). The excellent sealing property of the hot melt adhesive material and excellent physical and chemical properties reach insulation, temperature resistance, impact resistance and reduction. Shock, moisture, waterproof, dustproof, chemical resistant, etc. Currently the technology is widely used in smart home, automotive electronics, consumer electronics and 4G/5G communication.

In addition, representatives from Zhejiang Dafeng Technology, China Household Electrical Appliances Research Institute, and Midea, Wanhe and other companies have shared technology in related fields. For example, “Embedded Control System Functional Safety C Grade in Life Appliance Design Feasibility Analysis and Application Practice, "Natural Convection Numerical Simulation and Parametric Analysis of Its Impact Factors", "Summary of Technical and Management Requirements for Use of Qualified Reusable Components", "Experimental Study of Humidifier Humidification Process", "Vacuum Cleaner Cup Analysis and optimization of dust separation mechanism and so on.
