The present invention discloses an air volume adjustment device for a refrigerator. The air volume adjustment device comprises: a fan capable of introducing cold air from an evaporator into the first air inlet cavity and the second air inlet cavity; a baffle arranged between a first air inlet cavity of a first compartment and a second air inlet cavity of a second compartment, which is capable of moving among a plurality of positions to adjust the volume of air entering the first air inlet cavity and the second air inlet cavity; and an operating knob and a potentiometer which are connected to the front side and the rear side of the baffle, respectively. The operating knob is capable of operably driving the baffle to move. The potentiometer transfers an electrical signal corresponding to a position of the baffle to the controller for controlling the fan or the compressor.

A control method for a refrigerator comprises driving a first cooling fan to cool a first storage chamber; adjusting a damper to cause cold air to simultaneously flow through first and second cold-air passages; adjusting a damper to reduce the opening angle of the first cold-air passage, when the temperature of a high-temperature chamber reaches a value smaller than or equal to a second reference temperature for the high-temperature chamber; adjusting a damper to reduce the opening angle of the second cold-air passage, when the temperature of a low-temperature chamber reaches a value smaller than or equal to a second reference temperature for the low-temperature chamber; and driving a second cooling fan to cool a second storage chamber. When a predetermined time elapses or the sensed temperature of the high-temperature chamber reaches a first set temperature, the damper is adjusted to increase the opening angle of the first cold-air passage.

Apparatus for the display and distribution of products, including a cabinet for containing the products displayed for sale, equipped with a closing door provided with a display and with a double-glazing window unit. The apparatus also includes a video camera for transmitting to an electronic component (computer processor) user data detected by the video camera, where the electronic component sends to the aforementioned display a specific multimedia content, formulated on the basis of the data detection performed by the video camera. In comparison with the known apparatuses for the display and automatic distribution of products in general, the apparatus according to the invention offers the advantage of selecting the information and messages that appear on the display according to the preferences and tastes of the user, determined based on detection of the images of the latter which are acquired through the video camera fitted on the same apparatus.

Disclosed are various embodiments for an automated temperature logging and predictive alerting system for monitoring items that are being cooled or heated. In one embodiment, a predictive logging application may compare a predicted temperature curve of an item to a predefined slope to predict whether or not the item will meet a target threshold. The target threshold may be a target temperature or duration rule that can be aggregated discontinuously over a single day or multiple days. If the projected temperature curve is predicted to not meet the target threshold, the logging application may send alerts notifying a client of available corrective actions. In projecting the predicted slope, the predictive logging application may train machine learning models to analyze historical data associated with the item and the user.

An artificial intelligence device includes a temperature sensor configured to measure a temperature of a product to be frozen, and a processor configured to acquire, via the temperature sensor, temperature distribution information about at least a part of the product, acquire frozen state information including at least one of freezing progress information, surface temperature information, or ambient temperature information about the product, based on the temperature distribution information about the product, and acquire a remaining freezing time until the product is frozen to a target frozen state, based on the frozen state information about the product.

A system is provided and includes refrigerated storage containers (20), local controllers (30) respectively coupled with corresponding refrigerated storage containers (20) to control operations thereof in accordance with controller parameters and a supervisory controller (40). The supervisory controller (40) is configured to issue control commands to the local controllers (30) based on respective responses of the refrigerated storage containers (20) to local controller control.

An enclosed unit for thawing a food product is provided. The unit includes a food storage compartment and auxiliary compartment. The auxiliary compartment receives air flow from the food storage compartment and directs air across an evaporator and a heating element. A controller controls operation of the evaporator and the heating element to control the temperature around one of several nominal temperature levels associated with a recipe to thaw frozen food items disposed within the food storage compartment in a controlled manner, which is faster than placing the food within an initially refrigerated compartment for thawing.

An artificial intelligent food refrigerating device and a method for refrigerating food by using the same are disclosed. An artificial intelligent food refrigerating device according to the present disclosure identifies the size, volume, type, and quantity of food to be put into it and determines a target refrigeration temperature and refrigeration time for the food based on an identification result. The artificial intelligent food refrigerating device and method according to the present disclosure may be associated with an artificial intelligent module, a robot, an augmented reality (AR) device, a virtual reality (VR) device, a 5G service-related device, etc.
