Meanwhile, the processor 260 may control the audio input unit 220 , the audio output unit 291 , the communication unit 270 , and the like.

Hereinafter, the difference from FIG. 5 will be mainly described.

The processor 260 may process a user's voice input signal received through the audio input unit 220 and perform a voice recognition process.

For example, when a wake up voice signal including a preset call word is received, the processor 260 may be switched to a state for receiving a voice command. In this case, the processor 260 may only perform a voice recognition process up to whether or not the calling word is inputted, and subsequent voice recognition for the user's voice input may be performed through the voice recognition server system.

The processor 260 may control a user's voice command input after recognition of a wake up voice signal to be transmitted to the voice recognition server system through the communication unit 270 .

For example, the cabinet 12 may include a sliding door motor 810, a gear member for moving the sliding door 11 to the left or right according to the rotation of the sliding door motor 810, a rail member, etc. can

The air conditioner according to an embodiment of the present invention may move the mechanical structure using a step motor. The step motor rotates in proportion to the number of pulses, and the rotation speed changes in proportion to the input frequency. Therefore, since the movement amount of the mechanical structure is proportional to the number of pulses, there are advantages of simple control and low price.

Accordingly, a step motor may be used as the sliding door motor 810 . In this case, the sliding door motor 810 may also be referred to as a sliding door step motor 810 .

The control unit 240 may open or close the sliding door 11 by rotating the sliding door motor 810 .

For example, the control unit 240 controls the sliding door 11 to move to the left to open based on a sliding door on command, and based on a sliding off command, the sliding door ( 11) can be controlled to move to the right and close.

Meanwhile, when the sliding door 11 is opened and closed by sliding in the left and right direction, noise may occur during overswing. Such noise generation may cause discomfort to the user and reduce product reliability.
