The plurality of temperature sensors may each be installed in each of the plurality of storage compartments 20 to detect the temperature of each of the plurality of storage compartments 20, and may output an electrical signal corresponding to the detected temperature to the controller 190. Each of the plurality of temperature sensors may include a thermistor whose electrical resistance changes depending on the temperature.
The door open/close sensor 195 may output whether the door 300 is opened as a preset determination value, as described above. For example, the door open/close sensor 195 may output 1 in response to the door 300 being opened, and may output 0 in response to the door 300 being closed.
The door open/close sensor 195 may also be implemented as a distance sensor. Based on a distance between the door 300 and the main body being greater than or equal to a reference distance, the door open/close sensor 195 may determine that the door 300 is opened, and based on the distance being less than the reference distance, the door open/close sensor 195 may determine that the door 300 is closed.
However, the door open/close sensor 195 is not limited thereto, and any configuration of sensor may be used as long as it may determine whether the door 300 is opened and may output a preset determination value.
The cooling portion 170 may supply cold air to the storage compartment. Specifically, the cooling portion 170 may maintain a temperature of the storage compartment within a range set by a user by using a circulation of refrigerant in a refrigerant circuit.
The cooling portion 170 may include a compressor 171 for compressing the gaseous refrigerant, a condenser 172 for converting the compressed gaseous refrigerant into a liquid state, an expander 173 for decompressing the liquid refrigerant, and an evaporator 174 for converting the decompressed liquid refrigerant into a gaseous state. The cooling portion 170 may cool the air in the storage compartment using a phenomenon in which the liquid refrigerant absorbs heat energy of the surrounding air during a phase change of the refrigerant from a liquid state to a gaseous state.
However, the cooling portion 170 is not limited to including the refrigerant circuit. For example, the cooling portion 170 may include a Peltier element using the Peltier effect or a magnetic cooling material using the magneto-caloric effect.
The communication circuitry 180 may exchange data with an external device such as a server device and/or a user device and/or the display 200 and/or a cooking appliance.
The communication circuitry 180 may include a wired communication module 182 that exchanges data with external devices by wire, and a wireless communication module 181 that exchanges data with external devices wirelessly.
The wired communication module 182 may access a wired communication network and communicate with external devices through the wired communication network. For example, the wired communication module 182 may access a wired communication network over Ethernet (IEEE 802.3 standard), and may receive data from external devices through the wired communication network.
The wireless communication module 181 may wirelessly communicate with a base station or an access point (AP), and may access a wired communication network through the base station or the access point. The wireless communication module 181 may also communicate with external devices connected to the wired communication network via the base station or the access point. For example, the wireless communication module 181 may wirelessly communicate with an access point (AP) using Wi-Fi (IEEE 802.11 standard), or may communicate with a base station using code division multiple access (CDMA), wideband code division multiple access (WCDMA), global system for mobile communication (GSM), long term evolution (LTE), WiBro, and the like. The wireless communication module 181 may receive data from external devices via the base station or the access point.
In addition, the wireless communication module 181 may communicate directly with external devices. For example, the wireless communication module 181 may wirelessly receive data from external devices using Wi-Fi, Bluetooth™ (IEEE 802.15.1 standard), ZigBee (IEEE 802.15.4 standard), and the like.
As such, the communication circuitry 180 may exchange data with external devices, and in particular, may receive video data including video and/or audio from the external devices, and may output the received data to the controller 190.
The controller 190 may process a user input and/or door open/close detection data and/or communication data, and may control the components of the refrigerator 1 based on the data processing.
The controller 190 may include memory 192 that stores/records a program and/or data, and a processor 191 that processes a user input and/or door open/close detection data and/or communication data according to the program and/or data stored in the memory 192.
The memory 192 may store/record a program and/or data. A program includes a plurality of instructions combined to perform a specific function, and data may be processed by a plurality of instructions included in the program. In addition, the program and/or data may include a system program and/or system data directly related to an operation of the refrigerator 1, and an application program and/or application data that provide convenience and fun to a user.
The memory 192 may include a non-volatile memory that stores a program and/or data for controlling the components of the refrigerator 1, and a volatile memory that stores temporary data generated while controlling the components of the refrigerator 1.
For example, the non-volatile memory may store programs and/or data electrically, magnetically, or optically. The non-volatile memory may include, for example, read only memory (ROM) and flash memory for long-term data storage. In addition, the non-volatile memory may include solid state drive (SSD), hard disc drive (HDD), optical disc drive (ODD), and the like.
For example, the volatile memory may load programs and/or data from non-volatile memory, and may electrically store programs and/or data. The volatile memory may include, for example, static random access memory (S-RAM) and dynamic random access memory (D-RAM), and the like for temporarily storing data.
The memory 192 may store/record programs and data such as an operating system (OS), middleware, and applications, and may provide the programs and data to the processor 191 in response to a request from the processor 191.
The processor 191 may process a user input on the display 200 and/or detection data of the proximity sensor 160 and/or communication data of the communication circuitry 180 according to the program and/or data stored/recorded in the memory 192. In addition, the processor 191 may generate a control signal for controlling an operation of the camera 150, the display 200, and/or the communication circuitry 180 based on the data processing.
For example, the processor 191 may determine whether content being played on the display 200 is a stop target based on the at least one door 300 being opened, may pause the content based on the content being the stop target, and may play the content from the paused point based on the door 300 being closed. Whether the at least one door 300 is opened may be detected by the door open/close sensor 195.
In addition, the processor 191 may determine whether the content is a real-time video, and may determine the content as the stop target, based on the content not being the real-time video.
In addition, the processor 191 may determine that the content is not the real-time video based on the content being stored in the memory 192.
In addition, the processor 191 may determine that the content is the real-time video, based on playback data of the content including reference data.
In addition, the processor 191 may switch the display 200 to a power saving mode, based on the content being the real-time video and the at least one door 300 being opened.
In addition, the processor 191 may determine whether the content includes a video, and may determine the content as the stop target based on the content including the video.
In addition, the processor 191 may determine the content as the stop target, based on the amount of pixel data change of the content including the video being greater than or equal to a reference value.
In addition, the processor 191 may determine that the display 200 is abnormally terminated, based on the display 200 being turned off in a state where the at least one door 300 is closed. The processor 191 may store playback data at an end time point of the content in the memory 192, based on the display 200 being abnormally terminated, may determine whether the content is the stop target based on the playback data, and may play the content from the end time point based on the content being the stop target and the door 300 being closed.
The processor 191 may include a core that performs logic and arithmetic operations, and a register that stores the computed data.
As such, the controller 190 may process data collected from the sensors and may control the components of the refrigerator 1 based on the data processing. In particular, the controller 190 may provide various conveniences to a user, such as video playback, through the display 200.
However, when a user watches a video through the display 200, the watching is interrupted by the opening and closing of the door 300. Specifically, while the user is watching the video through the display 200 provided on the refrigerator door 300, the video continues to play even when the door 300 of the refrigerator 1 is opened. As a result, the user may miss a portion of the video until the door 300 is closed.
That is, when the user who has been watching the video opens the door 300, the user's gaze is directed toward the storage compartment of the refrigerator 1, and thus the user cannot watch the video. Accordingly, the user has to press a pause button and press a video restart button after closing the refrigerator door 300, which is inconvenient. Furthermore, when a different user other than the user who has been watching the video opens the door 300, the display 200 is outside the user's view, and the user who has been watching the video misses a portion of the video.
An embodiment related thereto is described below in detail with reference to

In this instance, the processor 191 may determine whether the video displayed on the display 200 is a stop target to be stopped when the door 300 is opened.
Specifically, in a case where the video displayed on the display 200 is a live video, the video cannot be stopped, and thus the processor 191 may determine that the video is not the stop target to be stopped in response to the opening of the door 300. That is, as shown in “a” of
Referring to
In addition, the door open/close sensor 195 provided on each door 300 may transmit information about whether each door 300 is opened to the processor 191, and thus the processor 191 may determine whether the door 300 equipped with the display 200 is opened or closed.
Accordingly, the processor 191 may determine whether the door 300 equipped with the display 200 is opened (510). For example, in a case where the processor 191 receives a value of 1 from the door open/close sensor 195 provided on the door 300 equipped with the display 200, the processor 191 may determine that the door 300 equipped with the display 200 is opened.
Based on determining that the door 300 equipped with the display 200 is opened (Yes in operation 510), the processor 191 may determine whether a video is being played on the display 200 (520). Whether a video is being played on the display 200 may be determined based on receiving a video playback signal from the memory 192 or the communication circuitry 180.
The processor 191 may determine whether the video being played on the display 200 is a video stored in the memory 192 (530). That is, the processor 191 may determine whether the video being played on the display 200 is the video stored in the memory 192 of the refrigerator 1 or the user device based on playback data of the video. In a case where the video is stored in the memory 192 of the refrigerator 1 or the user device, the processor 191 may determine that the video being played on the display 200 is a stored video, not a live video.
Based on determining that the video being played on the display 200 is not a video stored in the memory 192 of the refrigerator 1 or the user device, the processor 191 may determine whether live data is present in a streaming address based on the video playback data (540).
That is, the processor 191 may determine whether the live data is present in the video playback data that includes the streaming address of the video being played on the display 200, protocol information of the streaming address, playback time, and capacity. Here, the live data may be in the form of a flag indicating that the video is a live video, and in a case where the flag is 1, indicating that the video is a live video, and in a case where the flag is 0, indicating that the video is a recorded video that is non-live.
Based on determining that the video being played on the display 200 is the video stored in the memory 192 (Yes in operation 530) or that live data is not present in the streaming address (No in operation 540), the processor 191 may determine that the video is a stop target and may pause the video (550).
In addition, based on determining that the video being played is a live video that does not need to be paused (Yes in operation 540), the processor 191 may turn off the display 200 without pausing the video as illustrated in
That is, referring to
That is, the door open/close sensor 195 may determine that the door 300 is closed in a case where a distance between the main body 10 and the door 300 of the refrigerator 1 is less than or equal to a preset reference value, and may transmit a corresponding determination value to the processor 191.
Based on determining that the door 300 equipped with the display 200 is closed (Yes in operation 610), the processor 191 may turn on the display 200 (620). In addition, the processor 191 may play the paused video from the paused point (630). In this instance, turning on the display 200 and playing the paused video may be performed simultaneously.
Accordingly, the refrigerator 1 according to an embodiment may determine whether the video is a stop target that may be stopped, and when a user opens and closes the door 300 of the refrigerator 1, may automatically pause and play the paused video that is the stop target, thereby allowing the user to continuously watch the video.
Referring to
In this instance, the processor 191 may determine whether the video displayed on the display 200 is a stop target to be stopped when the door 300 is opened.
Specifically, in a case where the video displayed on the display 200 is an audio image without a video, stopping the video is not necessary, and thus the processor 191 may determine that the audio image is not a stop target to be stopped in response to the opening of the door 300.
That is, as shown in “a” of
Referring to
Based on determining that the door 300 equipped with the display 200 is opened (Yes in operation 810), the processor 191 may determine whether a video is being played on the display 200 (820). Whether a video is being played on the display 200 may be determined based on receiving a video playback signal from the memory 192 or the communication circuitry 180.
The processor 191 may determine whether video data is present in a streaming address based on video playback data (830).
That is, the processor 191 may determine whether the video data is present in the video playback data that includes data about whether the video being played on the display 200 includes video or audio, or the like. In this instance, the video data is in the form of a flag indicating whether the video includes video, and in a case where the flag is 1, indicating that the video includes video, and in a case where the flag is 0, indicating that the video includes only audio without video.
Based on determining that the video data is present in the streaming address of the video being played on the display 200 (Yes in operation 830), the processor 191 may determine that the video is a stop target and may pause the video (840).
In addition, based on determining that the video is an audio image that does not need to be paused (No in operation 830), the processor 191 may turn off the display 200 without pausing the video as illustrated in
In the refrigerator 1 according to an embodiment, playing the video or turning on the display 200 after turning off the display 200 is the same as in

Specifically, the processor 191 may display a video stored in the memory 192 of the refrigerator 1 or an image received from an external device (e.g., a user device or a server) through the communication circuitry 180.
In this instance, the processor 191 may determine whether the video displayed on the display 200 is a stop target to be stopped when the door 300 is opened.
Specifically, even though the video displayed on the display 200 includes video, in a case where the amount of pixel data change of the video is less than a reference value, stopping the video is not necessary, and thus the processor 191 may determine that the video is not a stop target to be stopped in response to the opening of the door 300.
That is, as shown in
That is, in a case where the video displayed on the display 200 consists only of a still image and the amount of pixel data change is less than the reference value, the processor 191 may determine that the video is not a stop target to be stopped in response to the opening of the door 300.
However, as shown in
That is, in a case where the video displayed on the display 200 consists of two or more consecutive still images and the amount of pixel data change is greater than or equal to the reference value, the processor 191 may determine the video as a stop target to be stopped in response to the opening of the door 300.
Referring to
Based on determining that the door 300 equipped with the display 200 is opened (Yes in operation 1010), the processor 191 may determine whether a video is being played on the display 200 (1020). Whether a video is being played on the display 200 may be determined based on receiving a video playback signal from the memory 192 or the communication circuitry 180.
The processor 191 may determine whether the amount of pixel data change is greater than or equal to a reference value in video data stored in the memory 192 (1030).
Based on determining that the amount of pixel data change in the data of the video being played on the display 200 is greater than or equal to the reference value (Yes in operation 1030), the processor 191 may determine that the video is a stop target and may pause the video (1040).
In addition, based on determining that the amount of pixel data change in the data of the video is less than the reference value (No in operation 1030), the processor 191 may turn off the display 200 without pausing the video as illustrated in
In the refrigerator 1 according to an embodiment, playing the video or turning on the display 200 after turning off the display 200 is the same as in
Referring to
Even in this case, the processor 191 may determine whether the video is a stop target to be stopped in response to an opening of the door 300 to allow the video to be played from a paused point.
Specifically, as described above, in a case where the video displayed on the display 200 is a live video, an image that includes only audio, or a still image even in a case of including a video, stopping the video is not necessary, and thus the processor 191 may determine that the video is not a stop target to be stopped in response to the opening of the door 300.
Thereafter, based on determining that the video immediately before the abnormal termination of the display 200 is the stop target, the processor 191 may store playback data at an end time point, and when the door 300 is closed, may play the video from the end time point.
Referring to
Based on determining that the door 300 equipped with the display 200 is opened (Yes in operation 1210), the processor 191 may determine whether a video is being played on the display 200 (1220). Whether a video is being played on the display 200 may be determined based on receiving a video playback signal from the memory 192 or the communication circuitry 180.
The processor 191 may determine whether the display 200 is turned off in a state where the door 300 is closed (1230). That is, in a case where the display 200 is turned off without user operation in a state where the door 300 is closed, the processor 191 may determine the above as an abnormal termination due to impact or power outage.
Thereafter, the processor 191 may determine whether the video immediately before the display 200 is turned off is a stop target, and based on determining that the video is the stop target, the processor 191 may store playback data at an end time point of the video in the memory 192 (1240).
In this instance, the playback data at the end time point of the video may include a source address of the video, a local file path, and a playback time.
Referring to
Thereafter, after the display 200 is turned off, the processor 191 may determine whether the door 300 equipped with the display 200 is closed (1310). In this instance, the processor 191 may use a determination value of the door open/close sensor 195 to determine whether the door 300 equipped with the display 200 is closed in the same manner as the operations of determining whether the door 300 equipped with the display 200 is opened in
Based on determining that the door 300 equipped with the display 200 is closed (Yes in operation 1310), the processor 191 may turn on the display 200 (1320). In addition, the processor 191 may play the paused video from the video end time based on the playback data stored in the memory 192 (1330). However, in this instance, turning on the display 200 and playing the paused video may be performed simultaneously.
Accordingly, even in a case where the display 200 is abnormally terminated, the refrigerator 1 according to an embodiment may determine whether the video is a stop target that may be stopped, and when a user opens and closes the door 300 of the refrigerator 1, may automatically pause and play the paused video that is the stop target, thereby allowing the user to continuously watch the video.
Meanwhile, the disclosed embodiments may be implemented in the form of a recording medium that stores instructions executable by a computer. The instructions may be stored in the form of program codes, and when executed by a processor, the instructions may create a program module to perform operations of the disclosed embodiments. The recording medium may be implemented as a computer-readable recording medium.
The computer-readable recording medium may include all kinds of recording media storing instructions that may be interpreted by a computer. For example, the computer-readable recording medium may be read only memory (ROM), random access memory (RAM), a magnetic tape, a magnetic disc, a flash memory, an optical data storage device, etc.
