An air cleaner includes: a housing including a suction portion suctioning air and a discharge portion discharging air, a frame disposed inside the housing, a sterilizer sterilizing the suctioned air, a filter assembly filtering air, a blower moving air, a flow converter disposed on a top surface of the housing, guiding a flow of air, and discharging air inside the housing to an outside, and a guide guiding a direction of the flow converter. The sterilizer includes a sterilizing light source generating sterilizing light, a first sterilizing casing accommodating the sterilizing light source, and a second sterilizing casing coupled to a lower portion of the first sterilizing casing and supporting the first sterilizing casing and the sterilizing light source, where a portion of the first sterilizing casing is spaced apart from the second sterilizing casing to define a space therebetween that dissipates heat generated from the sterilizing light source.

Air cleaner

A portable air purifier is provided that may include a fan module disposed between a suction opening and a discharge opening, a filter disposed between the suction opening and the fan module, and a lighting portion disposed between the discharge opening and the fan module.

Portable air purifier

An air cleaner may include a housing including a first housing having a discharge outlet through which air is discharged outside of the air cleaner, and a second housing including a suction inlet through which air is suctioned from outside of the air cleaner, and a filter assembly accommodated inside of the housing and that filters air. The first housing and the second housing may be spaced apart from each other, and the filter assembly may be replaceable through a space between the first housing and the second housing.

A hub device providing a diagnostic function and a diagnostic method using the same are disclosed. The hub device includes: a communication unit receiving a first type of data from plural service devices to transmit the first type of data to an access point device and receiving a second type of data from the access point device to transmit the second type of data to at least one of the service devices; and a controller controlling the communication unit and performing diagnosis for the service devices and the access point device.

Hub device with diagnostic function and diagnostic method using the same

A device and system for managing a service device provided with a communication module are disclosed, and the service device includes a communication unit directly communicating with either a hub device or an access point device and a device controller controlling the communication unit to perform connection to the hub device depending on communicative connectivity to the access point device.

Device and system for managing service device with communication module

Disclosed is an automatic registration system for home appliances, which may simplify the process of registering a home appliance using a gateway. The automatic registration system for home appliances includes a home appliance that automatically accesses a gateway using a password that is generated based on an SSID of the gateway; accordingly, the user does not feel that home appliance registration is cumbersome because the user itself does not need to connect a gateway and a home appliance.
