A water dispensing system for a refrigeration appliance includes a three-way connector operably coupled to an inlet water source and configured to direct incoming water from the inlet water source into an ambient water holding portion and a cold water tank. A water dispenser is coupled with said refrigeration appliance. A three-way control valve is configured to provide water to the water dispenser from at least one of the ambient water holding portion and the cold water tank. A valve actuator is slidable between first, second, and third positions. The three-way control valve is configured to provide water from the ambient water holding portion when the valve actuator is in the first position, from the cold water tank when the valve actuator is in the second position, and from both the ambient water holding portion and the cold water tank when the valve actuator is in the third position.

An object recognition method of a refrigerator is disclosed. The disclosed object recognition method of a refrigerator comprises the steps of: obtaining a captured image of a storage compartment of a refrigerator; checking the change in the imaging direction of an image capturing device which has captured the image of the storage compartment, when a change in the captured image is confirmed compared to a previously stored image; and performing an object recognition operation of the captured image when the imaging direction is maintained.

A refrigerator and a display for a refrigerator are provided. The display may include a display plate defining an outer appearance of a front surface of the display, a plurality of display portions that displays information of the refrigerator and is formed by an arrangement of a plurality of fine through-holes that pass through the display plate, a plurality of operational interfaces formed on a front surface of the display plate and operated by a touch input, a touch PCB provided on a rear surface of the display plate and including a plurality of touch sensors at positions corresponding to the plurality of operational interfaces, a display PCB on which a LED that radiates light toward the plurality of fine through-holes is mounted, and a display cover provided close to the rear surface of the display plate and on which the touch PCB and the display PCB are mounted.

A system generates alerts based on sensor data obtained from equipment, for example, refrigeration equipment. Examples of equipment instances include refrigeration equipment, heating equipment, air conditioning equipment, and so on. The system accesses a model, for example, a machine learning model trained to predict an alert threshold for generation of alerts. The system modifies the alert threshold value for an equipment instance based on the output of the machine learning model. The system uses the modified alert threshold value for generating alerts. The system may track the number of times the alert threshold was adjusted. If the number of times the alert threshold value is modified exceeds a predetermined fault threshold value, the system determines that the equipment is faulty.

The present invention discloses a refrigerator controlling method and system with a linear compressor. The method comprises: monitoring an environment temperature T of the refrigerator located in the environment comparing the environment temperature T with a preset environment temperature threshold T0; if T is larger than T0, controlling a refrigerating unit and/or a heating unit in the refrigerator such that the refrigerator runs under a first operation condition; and if T is smaller than or equal to T0, controlling the refrigerating unit and/or the heating unit in the refrigerator such that the refrigerator runs under a second operation condition. When the linear compressor runs within predetermined time, a refrigeration amount of the linear compressor under the second operation condition is controlled to be larger than a refrigeration amount of the linear compressor under the first operation condition, such that a compartment of the refrigerator reaches a target temperature.

A portable, self-contained, temperature-controlled enclosure capable of maintaining a constant, user-specified temperature within the enclosure independent of the outside environment. The device is ideal for the transport of material that is highly temperature sensitive and requires a stable temperature environment. The portable enclosure includes capability of cellular and GPS location beacon identification, comprehensive internal status and operation monitoring, and wireless communication capability of the device status, temperature and humidity parameters, and location using BLUE TOOTH, WIFI and/or cellular technology. The system is powered by an onboard rechargeable battery, external DC power, or external AC power.

An electrical system can include a diagnostic device that generates a first test signal at a first time. The electrical system can also include at least one energy transfer link coupled to the diagnostic device, where the first test signal flows through the at least one energy transfer link at the first time. The electrical system can further include a portable electrical load coupled to the at least one energy transfer link. The electrical system can also include a monitoring device coupled to the at least one energy transfer link, where the monitoring device is disposed between the diagnostic device and the portable electrical load. The first monitoring device can receive the first test signal, where the monitoring device executes, in response to the first test signal, a test procedure on the portable electrical load. The portable electrical load is portable relative to the diagnostic device.
