A refrigerator is provided. The refrigerator includes a camera, a thermal imaging camera, a display, and a processor configured to acquire an image that photographed the inside of the refrigerator through the camera, identify an object included in the acquired image, acquire information on the temperature of the identified object based on a thermal image that photographed the inside of the refrigerator through the thermal imaging camera, and control the display to display information on the identified object and information on the temperature of the identified object.

A high-precision control system and method for shipborne cryogenic flash freezing of an aquatic product using liquid nitrogen is described. The system may include a main control system, a display unit, a liquid nitrogen supply system, a valve control unit, an acquisition unit, and a power unit. A flash freezing process is divided into four stages: a precooling stage, a flash freezing stage, a deep freezing stage, and a thermal insulation stage. Different cooling rates and flash freezing times are used for different stages, where a cooling rate is used in the flash freezing stage is the highest, a cooling rate used in the deep freezing stage is next, a cooling rate used in the precooling stage is the lowest, and an ambient temperature in a device is kept stable in the thermal insulation stage.

A refrigerating apparatus applied to a refrigerator is disclosed. The refrigerating apparatus includes a refrigerant, a depressurization gas, an evaporator, a condenser, a first connecting pipe, a second connecting pipe, a third connecting pipe, a blower device and a refrigerator body. The evaporator is provided with an inlet and an outlet; the condenser is provided with a condensation cavity, a gas inlet, a gas outlet and a liquid outlet; a molecular sieve membrane is disposed in the condensation cavity; one end of the first connecting pipe is connected to the outlet and the other end to the gas inlet; one end of the second connecting pipe is connected to the liquid outlet and the other end to the inlet; one end of the third connecting pipe is connected to the gas outlet and the other end to the inlet.

A sensor device can be mounted on a pivotable door of a domestic refrigeration appliance. The sensor device includes an inertial sensor for supplying a motion signal as well as a processing device configured to determine a pivoting angle of the pivotable door on the basis of the motion signal and to output a signal when the pivoting angle has reached a predetermined threshold value. A household refrigeration appliance having a sensor device is also provided.

A control method of a refrigerating and freezing device and a refrigerating and freezing device are provided. The refrigerating and freezing device includes a cabinet defining a storage compartment. The control method includes a refrigerating operation step, a foodstuff determining step, and a cooling operation step. The refrigerating operation step is to control a temperature of the storage compartment to be within a first preset temperature range. The foodstuff determining step is to determine whether a new foodstuff is put into the storage compartment. The cooling operation step is to, when a new foodstuff is put into the storage compartment, cool the storage compartment. Since the temperature of the new foodstuff is greater than that of the original foodstuffs in the refrigerating and freezing device, cooling the storage compartment changes a storage temperature suitable for the foodstuffs originally stored in the storage compartment into a storage temperature suitable for the foodstuffs originally stored in the storage compartment into a storage temperature suitable for the new foodstuff, and the storage temperature is more convenient for the preservation of the new foodstuff and ensures good storage conditions for the newly put foodstuff. Furthermore, the preservation effect on the original foodstuffs will not be affected, and the preservation effect of the refrigerating and freezing device on the foodstuff is enhanced.

A domestic appliance has a housing, a transceiver unit and an electrically non-conductive covering. The housing delimits an interior accessible via a housing opening and has a frame which edges the housing opening. The transceiver unit contains an antenna for wirelessly receiving and transmitting signals. The domestic appliance has a door leaf, which is mounted pivotably relative to the housing and is provided to open and close the interior, or a drawer, which can be pulled partially out of the interior and has a front panel which closes the interior when in the pushed-in state. The housing, the door leaf or the front panel of the drawer has a cavity which is accessible via an opening in the housing, in the door leaf or in the front panel and inside of which the transceiver unit with the entire antenna is arranged. The electrically non-conductive covering covers the opening completely.

A household appliance, such as a refrigerator, has a body with a cooled compartment, a door that restricts and grants access to said cooled compartment, a foot assembly connected to the body, and an electrical connector support for supporting electronic components of the household appliance. The foot assembly includes at least one of an anti-tip foot to support the appliance and/or a wheel to facilitate moving the appliance. The electrical connector support includes a frame base portion connected to the foot assembly, a door sensor support attached to the frame base portion, and a door sensor configured to sense if the door is at an open or a closed position relative to the body. At least one component of the door sensor is attached to the door sensor support.
