Domestic electrical manufacturers are strengthening the sales of "IoT Home Appliances", which enhances added value by connecting home appliances to the Internet.The expansion of the new colon virus infection has increased home time, and cooking appliances and air conditioning equipment are popular.However, most of the collaboration works only between our products, and experts point out that "there is a limit to the spread in Japan while companies are running in the" enclosure of users "."

　In the world, household equipment that connects to the Internet, such as IoT home appliances, is spreading.According to the Ministry of Internal Affairs and Communications's 2020 version of the "Information and Communication White Paper", the number is expected to reach 8.7 billion units in 2010.Compared to 15 years of achievements, it is expected to be about four times, and it is expected that the world will spread rapidly.

　In Japan, Sharp has been launching IoT home appliances on the market for 15 years.In August 2001, the cumulative shipments exceeded 4 million units.Due to the demand for nesting due to the corona, the sales of the entire home appliance for 20 years have been strong, and the spread of IoT home appliances seems to have been boosted.

　The company's cooking appliances can add up to up to 1,000 kinds of recipes via the Internet.By linking with the refrigerator, recipes using the remaining ingredients can be proposed, and the person in charge emphasizes that the strength of IoT home appliances is that the product can be improved even after the release, such as updating the menu.This summer, in cooperation with venture companies (Minato -ku, Tokyo), a service will be launched to recreate the taste of the first -class chef, and will capture users.

　Meanwhile, Panasonic announced that 60 % of home appliances sold in Japan by FY2014 will be compatible with IoT.The goal is to raise the company's IoT home appliances to 10 million.In October, a "voice push notification" was launched to inform home appliances with television and speakers on the operating status of washing machines and robot vacuum cleaners and the time of consumables replacement.Next spring, we plan to add a function to notify the delivery schedule of courier service.

　In addition, in order to respond to the growing awareness of hygiene due to the corona evil, each company will also focus on linking air conditioners.While controlling the air volume and wind direction of the air conditioner, the functions that use the air purifier to collect droplets and other droplets, are also provided by Panasonic and Sharp, as well as Daikin Industrial products.

　Each company wants to dig up new demand by responding to IoT in the mature home appliance market.However, Researcher Hideyuki Araki of Resona Research Institute said, "It is difficult to spread unless cooperation beyond the barriers of companies does not progress."In Europe and the United States, home appliances are connected through smart speakers equipped with artificial intelligence (AI) provided by Google and Apple, and "strengthening its own functions by domestic companies is the risk of promoting Galapagos."

　There are new initiatives to overcome this situation.In November 2001, Mitsubishi Estate, which began providing rental apartments that can operate indoor appliances with a smartphone application, develops apps independently so that they can manage home appliances from multiple manufacturers.(Hironori Kuwashima)
