Abstract: The present disclosure relates to a laundry treatment machine. A laundry treatment machine according to an embodiment of the present disclosure includes: an inverter converting a direct current (DC) voltage from a converter into an alternating current (AC) voltage based on a switching operation and outputting the converted AC voltage to a circulation pump motor; and a controller to control a speed of the circulation pump motor to be increased before a time point at which a speed of a washing tub motor increases. Accordingly, the washing tub motor and the circulation pump motor can be operated in synchronization with each other. As a result, it is possible to improve washing power based on circulation pumping during washing.

Abstract: The present invention relates to a smart refrigerator having a function of providing information, which a user needs, through an app by using control data inside the refrigerator. The smart refrigerator according to the present invention has: a night function of allowing a user to set a mode required at night; an app display function of showing state information of the refrigerator on a display window of the refrigerator or on a mobile app (application) of a user through wired/wireless communication; an inducing function of, through real-time monitoring of a state of the refrigerator, inducing a user to take a specific action when the state of the refrigerator is out of a normal state; and the like. According to the present invention as described above, a user can identify a state of a refrigerator from a distance, and can take action when abnormalities occur in the state of the refrigerator, storage of food, or the like.
