Abstract: Disclosed is a system for providing an Internet-of-things (IoT) device integrated control service, in particular, a system for providing an IoT device integrated control service through an artificial intelligence (AI) server, in which a plurality of users can collectively control and manage a plurality of IoT devices for a ‘smart home’ and a ‘connected car,’ owned or managed by the users through the AI server capable of analyzing a speech or a text, so that the plurality of IoT devices can be collectively controlled and managed with only one control command, thereby minimizing time and effort to individually control and manage the plurality of IoT devices.

Abstract: Disclosed is a system for providing chatbot services in an integrated way, in which a client can receive query processing services by immediately accessing at least one of other chatbot servers without changing a preexisting accessing means while being initially connected to a specific chatbot server, so that a user can use a plurality of query processing services without difficulties by linking the chatbot servers operated by the plurality of service providers, thereby minimizing the time, efforts and costs of the user who wants to receive the plurality of query processing services through the plurality of service providers.

Abstract: Disclosed is a system for linking chatbot services and contact center services, and more particularly to a system for linking chatbot services and contact center services, in which a client is allowed to receive a query processing service from at least one of other chatbot servers or other contact center servers without changing a preexisting connection state while being initially connected to a specific chatbot server or a specific contact center server, so that a user can easily use a plurality of query processing services by linking the chatbot servers and contact center servers operated by a plurality of service providers, thereby minimizing the time, efforts and costs of the user who wants to receive the plurality of query processing services through the plurality of service providers.

Abstract: Disclosed is a system for providing contact center services in an integrated way, in which a client can receive query processing services by immediately connecting to at least one of other contact center servers operated by service providers cooperating in a link service by a call transfer without changing a preexisting connection state while being initially connected to a specific contact center server, so that a user can use a plurality of query processing services without difficulties by linking the contact center servers operated by the plurality of service providers, thereby minimizing the time, efforts and costs of the user who wants to receive the plurality of query processing services through the plurality of service providers.

Abstract: There is provided a ceiling type air conditioner including a brush assembly for collecting foreign matters filtered by a filter. The brush assembly includes a brush that contacts the foreign matters filtered by the filter and a main body for collecting the foreign matters separated from the filter to store the foreign matters. Therefore, it is possible to effectively collect and store the foreign matters filtered by the filter in the main body due to the movement of the brush assembly. In addition, since a user does not have to exchange or clean the filter, it is possible to prevent inconvenience from being caused by exchanging or cleaning the filter and to prevent the filter from being contaminated.

Abstract: Enclosed is an air conditioner including a foreign matter collecting unit to secondarily collect foreign matter in a brush assembly when the brush assembly for firstly collecting and accumulating the foreign matter filtered by a filter automatically moves. Therefore, the foreign matter separated from the filter is firstly collected in the brush assembly, and the foreign matter can be secondly collected in the foreign matter collecting unit by moving the brush assembly. Therefore, the foreign matter filtered by the filter is automatically removed so that the inconvenient of exchanging and cleaning the filter can be settled and pollution of the filter can be prevented. Since the foreign matter is discharged to outdoor side by simply detaching the foreign matter collecting unit so that convenience of use can be enhanced.
