A control method for a drawer door of a refrigerator and the refrigerator. The refrigerator comprises a refrigerator body (100), a drawer door (200) mounted in the refrigerator body (100) in a front-back pushed and pulled mode, and a driving mechanism (300) driving the drawer door (200) to move forward and backward. The control method comprises: obtaining a door opening instruction or a door closing instruction; controlling the driving mechanism (300) to drive the drawer door (200) to move forward to open or move backward to close; detecting a resistance borne by the drawer door (200) during the movement; determining whether the resistance is greater than a preset resistance threshold; and if yes, controlling the driving mechanism (300) to stop running to enable the drawer door (200) to stop moving. According to the method, the problem that the drawer door (200) is difficult to open is solved, and the automatic opening and closing process of the drawer door (200) is more controllable.

Disclosed are a refrigerator diagnostic method and a refrigerator using an artificial intelligence algorithm (AI) and/or machine learning algorithm in a 5G environment connected for the Internet of things. The refrigerator diagnostic method may include determining an installation state of a refrigerator based on a power value of a compressor provided in the refrigerator and the number of revolutions of a cooling fan provided in the refrigerator, when an operating time after initial installation of the refrigerator is less than or equal to a particular value, and determining a malfunction and a cleaning state of the refrigerator based on the power value of the compressor and the number of revolutions of the cooling fan, when the operating time after initial installation of the refrigerator exceeds the particular value.

A refrigeration device includes: a refrigerator; a heat pipe that includes a condensation unit connected to the refrigerator and adapted to condense a refrigerant, includes an evaporation unit connected to a storage chamber and adapted to evaporate the refrigerant, and includes a piping for circulating the refrigerant between the condensation unit and the evaporation unit; a heat pipe temperature sensor that detects a temperature of the heat pipe; and a control unit that controls driving of the refrigerator based on a result of detection by the heat pipe temperature sensor. The control unit controls the refrigerator so that the temperature of the heat pipe does not fall below a standard boiling temperature of the refrigerant.

Provided is a refrigerator and control method for refrigerator and method for opening a refrigerator door. While a user is holding an object in both hands, a door may be automatically and additionally opened using another part of a body other than hands.

A refrigerator is provided. The refrigerator may include a main body having a storage compartment, a first door rotatably installed at a first side of the main body to open and close a first portion of the storage compartment, and a second door rotatably installed at a second side of the main body to open and close a second portion of the storage compartment. A first camera may be installed at the first door to take a picture of an interior of the first storage compartment during rotation of the first door, and a second camera may be installed at the second door to take a picture of the interior of the first storage compartment during rotation of the second door. A controller may combine plural pictures taken by the first camera and the second camera into a single corrected image of a region of the first compartment spanning from the first door to the second door.
