Patent Description:
The present invention relates to a humidification and air cleaning apparatus equipped with an input assembly.

Air conditioners include an air conditioner that controls the temperature of the air, an air purifier that removes foreign substances from the air to maintain cleanliness, a humidifier that provides moisture to the air, and a dehumidifier that removes moisture from the air.

Conventional humidifiers are classified into a vibration type that atomizes water from a vibration plate and discharges it into the air, and a natural evaporation type that evaporates naturally from a humidification filter.

The natural evaporation humidifier is classified into a disk type humidifier evaporating the water on the surface of the disk by rotating the disk with the driving force, and a humidification filter-type humidifier naturally evaporating the water soaked into the humidification medium in which the air flows.

The main purpose of the conventional humidifier is to humidify the air, and the main purpose of the conventional air purifier is to filter foreign substances in the air. To compensate for this, a humidification cleaning device that simultaneously humidifies and filters air has been developed.

Conventional humidification and cleaning devices are operated by receiving a remote control signal or inputting a user's control signal.

With the development of technology, types of home appliances provided in homes are increasing, and various kinds of additional functions provided in home appliances are increasing. Accordingly, research has been actively conducted to apply artificial intelligence technology to the humidification and cleaning device and to allow the user to control the humidification and cleaning device with voice.

The air guide <NUM> combines the upper inner body <NUM> and the upper outer body <NUM>. The air guide <NUM> guides air to the water tank <NUM>.

Since the upper body assembly <NUM> separates the connection flow path <NUM> and a space <NUM> where the water tank is inserted, it is possible to minimize the inflow of water in the water tank <NUM> into the connection flow path <NUM>. Especially, since the connection flow path <NUM> is disposed outside a space in which the water is stored due to separation by the upper inner body <NUM>, it is possible to prevent water from flowing into the connection flow path <NUM>.

The upper side of the upper inner body <NUM> is opened and the water tank <NUM> is inserted thereinto. The upper inner body <NUM> forms a part of the clean connection flow path <NUM> where the filtered air is introduced.

An upper inlet <NUM>, corresponding to an air wash inlet <NUM>, is formed in the upper inner body <NUM>. The upper inlet is not the essential element. It is enough that the upper inner body <NUM> has a shape enabling the upper body assembly <NUM> to expose the air wash inlet to the connection flow path <NUM>.

The upper inner body <NUM> has a basket shape as a whole. The upper inner body <NUM> has a circular shape when it is viewed from the horizontal cross-section.

The input assembly <NUM> is disposed at the lower body <NUM> and is exposed to outside of the lower body <NUM>. In the present embodiment, the input assembly <NUM> is disposed to face the front. Unlike the present embodiment, the input assembly <NUM> may be disposed to face other direction.

The speaker <NUM> is installed in the resonant space <NUM> disposed at the frontal surface of the filter housing <NUM>. Since the resonant space <NUM> is opened to the front, sound from the speaker <NUM> may propagate effectively to the front.

The speaker <NUM> is assembled to the front wall <NUM> of the filter housing <NUM>.

Although the speaker <NUM> is hidden by the lower cover <NUM>, the speaker may realize enough volume by the resonant space <NUM>.

The voice recognition control unit is installed at the filter housing <NUM>. In the present embodiment, the voice recognition control unit <NUM> is assembled to the right wall <NUM> of the filter housing <NUM>. The voice recognition control unit <NUM> controls the speaker <NUM> and a microphone <NUM> of the input assembly <NUM>.

The voice recognition control unit <NUM> is electrically connected with the microphone <NUM> and the speaker <NUM>. The voice recognition control unit <NUM> is connected with a voice server <NUM> via a fixed-line or wireless network. The voice recognition control unit <NUM> sends and receives a data with the voice server <NUM> via the fixed-line or wireless network.

For example, when the user speaks words containing the wake-up word (e.g., Hi, LG), the microphone <NUM> send the words containing the wake-up word to the voice recognition control unit <NUM>, and the voice recognition control unit <NUM> transmits the sent voice signal to the voice server <NUM>. In this case, the voice recognition control unit <NUM> may reduce the noise and sense the wake-up word. The voice recognition control unit <NUM> sends the natural language to the voice server <NUM>.
