The present disclosure relates to a display assembly and a refrigerator including the same, and more particularly, to a display assembly that may be easily manipulated by a user, and a refrigerator including the same.
A refrigerator is an apparatus that may be used to freeze or refrigerate food. The refrigerator typically includes a casing having a storage compartment defined therein divided into a freezing compartment and a refrigerating compartment, and a refrigeration cycle apparatus including a compressor, a condenser, an evaporator, and an expansion valve. The refrigeration cycle apparatus is configured to lower a temperature of the freezing compartment and the refrigerating compartment.
The casing is equipped with a door to open and close the freezing compartment and the refrigerating compartment. In the refrigerator having such a configuration, the compressor compresses a low-temperature low-pressure gaseous refrigerant into a high temperature and high pressure state. Then, the compressed high-temperature high-pressure gaseous refrigerant is cooled and condensed as it passes through the condenser, and then become a high-pressure liquid state. As the refrigerant in the high-pressure liquid state passes through the expansion valve, its temperature and pressure are lowered. Then, the refrigerant turns into a low temperature low pressure gas state by the evaporator to take heat from surroundings and cool surrounding air. This refrigerating cycle may perform the cooling operation.
Various functions are applied to the refrigerator. Thus, it is important for the user to readily understand and use the various functions.

A refrigerator according to an embodiment of the present disclosure may include a top mount-type refrigerator in which a freezing compartment and a refrigerating compartment as a storage compartment for storing food therein are arranged vertically such that the freezing compartment is disposed above the refrigerating compartment, a bottom mount-type refrigerator in which a freezing compartment and a refrigerating compartment are arranged vertically such that the freezing compartment is disposed below the refrigerating compartment, or a side-by-side type refrigerator in which the freezing compartment and the refrigerating compartment are arranged horizontally.
In the present embodiment, the present disclosure will be described for convenience of description, based on a bottom freezer-type refrigerator in which the freezing compartment and the refrigerating compartment are arranged vertically, and the freezing compartment is disposed below the refrigerating compartment, such as shown in
A cabinet of the refrigerator may include an outer casing 10 defining or forming an overall appearance, and an inner casing 12 defining or forming a storage compartment 22 therein for storing food or other items therein. A predetermined space may be defined or formed between the outer casing 10 and the inner casing 12 so that cold air may circulate through the predetermined space. In one example, an insulation member may be formed between the outer casing 10 and the inner casing 12 so that air in the storage compartment 22 may be kept relatively cold as compared to an outer air (e.g., air outside the refrigerator).
In addition, a machine room (not shown) located in the space between the outer casing 10 and the inner casing 12 may contain a refrigerant cycle apparatus which circulates the refrigerant to generate cold air. The refrigerant cycle apparatus may be used to maintain freshness of foods stored in the refrigerator storage compartment. The refrigerant cycle apparatus includes a compressor for compressing a refrigerant, an evaporator (not shown) for converting a liquid refrigerant into a gaseous phase such that heat exchange occurs.
The refrigerator may have doors 20 and 30 for opening and closing the storage compartment. In this connection, the doors may include a freezing compartment door 30 and a refrigerating compartment door 20. Each door may be pivotally provided at one edge of the cabinet of the refrigerator via a hinge. Each of the freezing compartment door 30 and the refrigerating compartment door 20 may have a plurality of sub doors. That is, as shown in
A foam material may fill the space between the outer casing 10 and the inner casing 12 so that the outside and the storage compartment 22 may be thermally insulated from each other.
The storage compartment 22 may be defined by the inner casing 12 and the door 20 in an insulated manner from the outside of the refrigerator. The storage compartment 22 may be isolated from the outside of the refrigerator when the door 20 is closed. In other words, the storage compartment 22 may be defined by an insulation wall as the door 20 and an insulation wall as the casings 10 and 12 in an insulated manner from the outside of the refrigerator.
The cold air supplied from the machine room may flow throughout the storage compartment 22, so that the food stored in the storage compartment 22 may be kept at a low or desired temperature.
The storage compartment 22 may include a shelf 40 on which the food may be disposed. In this connection, a plurality of shelves 40 may be arranged vertically. The shelf 40 may fully or partially partition the interior of the storage compartment vertically.
The storage compartment 22 may include a drawer 50 that may be retracted or extended from the storage compartment 22. In one example, left and right side drawers 40 may be arranged in the storage compartment 22. The user may open a left door of the storage compartment 22 to access the left drawer. The user may open a right door of the storage compartment 22 to access the right drawer. Such configuration is an energy saver.
The storage compartment 22 may be divided into a first sub space located above a lowest shelf 40, and a second sub space defined in the drawer 50.
The cold air may flow between the freezing and refrigerating compartments. The cold may freely flow in each of the freezing and refrigerating compartments. The cold air may freely flow between divided sub spaces in each of the freezing and refrigerating compartments. For example, the cold air in the first space located above the lowest shelf 40 may flow into the second sub space defined in the drawer 50.
The display assembly which provides the user with information about an interior state of the refrigerator and allows the user to input a command thereto may be located on a top edge of the door 30 but is not limited to any particular location. The top edge of the door 30 may be a surface that is parallel to the ground. In other words, the user may access the display assembly on the top edge of the door 30 while the door 20 is opened. Further, when both of the door 20 and the door 30 are closed together, the display assembly is not exposed to the user. More particularly, for example, the door 20 may cover or block access to the display assembly located on the top edge of the door 30 when the door 20 is closed.
In another example, the display assembly may be installed in other positions than the top edge of the door 30. The display assembly may be placed inside the storage compartment 22 and may be placed in various positions on front faces of the doors 20 and 30.
Referring to
The display panel 100 may include a touch panel 140 to operate via a user's touch (display panel 100 controls are not limited to touch type controls, and may be any input generating device to facilitate input of control instructions by a user). The touch panel 140 may constitute a portion of the display assembly 100 and may be positioned around a menu for user selection. Therefore, when the user touches a location adjacent to the menu, the touch panel 140 recognizes the touch and transmits information to a controller 200 or processor that the user selected the corresponding menu. The controller 200 is capable of executing the various tasks and processes described herein. See, e.g.,
In one example, a plurality of the touch panels 140 may be disposed in various places on the display assembly 100. The touch panels 140 may be separated from each other such that a corresponding touch panel detects the user touch thereof.
In an embodiment, the display assembly 100 may include a first LED 110 to display information regarding a temperature. The first LED 110 may display a set temperature of the storage compartment or a current temperature of the storage compartment. When the first LED 110 is activated, information about the temperature is displayed on the display assembly 100 so that the user may obtain the related information. The controller 200 may be configured to control the first LED 110 to be turned on or off, thereby selectively providing the related information to the user.
In one example the first LED 110 may indicate whether a currently selected storage compartment is a freezing compartment, a refrigerating compartment, or another type of compartment such as a vegetable compartment. When the first LED 110 is activated, the user may be provided with temperature information about which storage compartment is being displayed.
In one embodiment, the second LED 120 displays information regarding a user-selectable menu. The user-selectable menu may include, for example, a water filter reset, ice plus, ice on/off, smart grid, WiFi, and/or auto door/ power.
For example, when the controller 200 activates the second LED 120 such that the second LED 120 is turned on, information about a menu selectable by the user may be provided to the user. For example, when the second LED 120 is activated by the controller 200, all menu information that may be commanded, controlled, selected, or operated by the user may be displayed.
In an embodiment, the third LED 130 may display information about a menu that the user has already selected. The third LED 130 may be composed of a pictogram, so that the user may easily recognize the relevant information.
A plurality of the third LEDs 130 may be provided (such as shown in
In one example, the third LED 130 may be blinkingly activated to inform another type information of the user. For example, when the third LED 130 is blinking, this may indicate to the user that the menu needs to be set.
The third LED 130 may be disposed adjacent to a corresponding menu, and thus may indicate that the menu corresponding to the third LED 130 and the menu corresponding to the second LED 120 are related to each other. For example, as shown in
The controller 200 may be configured to receive a signal about the user's contact from the touch panel 140 (again, the control is not limited to a touch panel 140). In addition, the controller 200 may be configured to turn on or off of one of the first LED 110, the second LED 120, the third LED 130, or some of the first LEDs 110, some of the second LEDs 120, or some of the third LEDs 130.
The controller 200 may be configured to activate some of the third LEDs 130 together while activating the first LED 110. In this connection, the user may obtain information provided from the first LED 110 and information provided from the third LED 130.
For example, when the controller 200 activates the first LED 110, the controller 200 may disable the third LED 130. On the other hand, the controller 200 may activate the third LED 130 but not the first LED 110. Since the information provided by the first LED 110 and the information provided by the third LED 130 are not simultaneously provided to the user, the user may obtain a small amount of information sequentially, so that the related information may be more easily recognized by the user.
A plurality of the touch panels 140 may be provided. When a user touch of each touch panel 140 adjacent to each menu is detected, the corresponding menu may be selected.
The touch panel 140 may be disposed outside the menu corresponding to the second LED 120. The touch panel 140 may has a strip-like shape but is not limited thereto. In another example, the touch panel 140 may have a square shape containing the menu corresponding to the second LED 120.
A deactivation shield 150 may be disposed between adjacent two of the plurality of touch panels 140 so that two touch panels 140 may be separated from each other via the deactivation shield 150. When the user touches a region between two menus, the deactivation shield 150 may deactivate the touch panel 140 that none of the two menus is selected. The deactivation shield 150 may be disposed between two touch panels 140 so that the touch panels 140 may not detect the touch when the user touches the region between the two touch panels 140. Such configuration reduces user input error.
The first LED 110 may be disposed at the center portion of the display assembly 100. The third LEDs 130 may be disposed at the left and right sides to the first LED 110. The fourth LEDs 140 may be disposed at the outermost region.
Referring to
The door sensor 160 is configured to detect whether the door 20 is open S10 or closed. When the door 20 is open, the display assembly 10 installed on the top edge of the door 30 or in another location may be exposed to the user. The user may check the information provided on the display assembly 10. The display assembly is not limited to being located in a location that is only exposed to the user when the door 20 is open.
When the door 20 detects that the door 20 is open, the first LED 110 and some of the third LEDs 130 may be activated. Accordingly, the user may check the information provided from the first LED 110 and some of the third LEDs 130.
The first LED 110 may allow the user to determine which type storage compartment the display assembly 100 provides information about (e.g., freezer, refrigerator, etc.), and to determine a current internal temperature of the corresponding storage compartment or a set temperature of the corresponding storage compartment.
While the first LED 110 is activated, the menu that the user has already selected and is being executed may be displayed on the third LED 130 S20. That is, the user may simultaneously recognize the information provided on the first LED 110 and the information provided on the third LED 130.
The information provided on the third LED 130 may be expressed in a form of an icon or pictogram, so that the user may easily grasp a meaning thereof. The invention is not limited to any particular expression or style of information provided on the third LED 130.
In
In
In this connection, for example, a state in which some of the third LEDs 130 are turned on is maintained.
The user may not recognize the information provided on the first LED 110, but may recognize the information provided on some of the seconds LED 120 and some of the third LEDs 130. In this way, too much information is not provided to the user at one time, so the information provided on the display assembly 10 may be more easily recognized by the user.
As shown in
In other words, when the user is initially aware of the temperature of the storage compartment and touches another touch panel to change a menu, information about the menu that may be set or controlled by the user may be provided on the second LED 120 to the user.
As shown in
When the touch panel 140 adjacent to the smart grid menu detects that the user selects a smart grid menu, as shown in
As shown in
When the door 20 is closed or when there is no touch on the touch panel 140 for a certain predetermined time duration S70, the controller 200 may be configured to turn off the second LED 120 and turn on the first LED 110. That is, when the door sensor 160 detects that the door 20 is closed, this may be considered as a situation where it may not be necessary to provide a user with a selectable menu. In addition, when the touch panel 140 does not detect the user touch for a certain predetermined period of time, this may be determined as a situation in which the user is no longer willing to select a menu, and there is no need to provide the user with a selectable menu.
Thus, the controller 200 may be configured to stop activating the second LED 120 to stop providing information about the user-selectable menu to the user. Instead, the display assembly 100 may display an initial screen which, for example, may provide the user with temperature information about the corresponding storage compartment.
In one example, while the first LED 110 is activated, the second LED 120 is not activated, but at least one the third LED 130 is still activated. In addition, while the second LED 120 is activated, the first LED 110 is not activated, but at least one the third LED 130 is still activated. Therefore, the user may continuously obtain information from the third LED 130 while the display assembly 10 is activated.
In one example, the third LED 130 may blink in order to inform the user of a specific alarm. In this connection, the specific alarm may be used to alert the user to select a specific function or to indicate that the specific function is abnormal.
The user may more easily recognize the information because the user is provided with the information from the first LED 110, the second LED 120, and the third LED 130 at the same time but the information from the first LED 110, the information from the second LED 120, and the information from the third LED 130 are sequentially displayed to the user.
Although the present disclosure has been described with reference to the drawings and embodiments as exemplified above, the present disclosure is not limited to the embodiments and the drawings disclosed herein. It is obvious that various modifications may be made thereto by a person skilled in the art within the scope of the present disclosure. In addition, it should be appreciated that effects to be achieved from configurations of the present disclosure as not expressly mentioned may be acknowledged.
