[0125] For example, the refrigerator (1a) may include a first door opening device (100A) configured to open a first door (30A). The first door opening device (100A) may be configured to press the first door (30A) to open a portion of the first storage room (21). For example, the refrigerator (1a) may include a second door opening device (100B) configured to open a second door (30B). The second door opening device (100B) may be configured to press the second door (30B) to open another portion of the first storage room (21). The operation of the first door opening device (100A) opening the first door (30A) and the operation of the second door opening device (100B) opening the second door (30B) may be performed independently of each other.

[0126] The door opening device (100) can be mounted on the main body (10). For example, the door opening device (100) can be mounted on the upper part of the main body (10). More specifically, the door opening device (100) can be accommodated inside the top table (13). The upper part of the door opening device (100) can be covered by the top table (13). The door opening device (100) can be placed on the upper surface of the outer surface (12).

That is, the first door opening device (100A) and the second door opening device (100B) may be positioned parallel to each other in the horizontal direction (Y). The first door opening device (100A) mounted on the upper part of the main body (10) may be provided to press the upper part of the first door (30A), and the second door opening device (100B) mounted on the upper part of the main body (10) may be provided to press the upper part of the second door (30B).

[0128] However, the present disclosure is not limited thereto, and the door opening device (100) may be mounted at various locations on the main body (10) and may be configured to open the storage room (20) by pressing various parts other than the upper part of the door (30). Unlike what is shown in the drawings, the door opening device (100) may be configured to press the lower part of the door (30). For example, the first door opening device (100A) may be mounted on the horizontal partition (17) and configured to press the lower part of the first door (30A). For example, the second door opening device (100B) may be mounted on the horizontal partition (17) and configured to press the lower part of the second door (30B).

[0129] The door opening device (100) may include a door pusher (120). The door pusher (120) may be provided to press the door (30) to open the door (30). The door pusher (120) may be provided to be movable relative to the main body (10). The door pusher (120) may be provided to press the door (30) while moving relative to the main body (10). In detail, the door pusher (120) may press the door (30) while moving forward from the side of the main body (10) toward the door (30), thereby opening the closed door (30).

[0130] For example, the door pusher (120) may be configured to move linearly back and forth relative to the main body (10). The door pusher (120) may be configured to move linearly in the forward and backward direction (X) relative to the main body (10). Alternatively, the door pusher (120) may move non-linearly relative to the main body (10).

[0131] The door opening device (100) may include a pusher case (110). The pusher case (110) may be provided to support a door pusher (120). The pusher case (110) may movably support the door pusher (120). The pusher case (110) may form a space for accommodating at least a portion of the door pusher (120). The door pusher (120) may be movably provided with respect to the pusher case (110). The door pusher (120) may be movably provided between a position where it is maximally retracted into the internal space of the pusher case (110) and a position where it is pulled forward from the internal space of the pusher case (110).

[0132] The pusher case (110) can be mounted on the main body (10). The pusher case (110) can be fixed to the main body (10). For example, the pusher case (110) can be coupled to the top table (13). However, the present disclosure is not limited thereto, and the pusher case (110) can be coupled to various locations on the main body (10).

[0133] The door opening device (100) may include a power unit (130, see FIG. 10) configured to generate power for opening the door (30). The power unit (130) may be configured to generate power for moving the door pusher (120). For example, the power unit (130) may include a drive motor and a motor driver connected to the drive motor. The drive motor may generate power by receiving a drive current from the motor driver.

[0134] The operation of the door opening device (100) can be controlled based on information obtained by the sensor (200). The operation of the door opening device (100) can be controlled based on a value (output signal) detected by the sensor (200). For example, the motor driver can be electrically connected to the control unit (60, see FIG. 10) of the home appliance (1), and the door opening device (100) can operate based on a control signal received from the control unit (60). That is, the power unit (130) can be controlled by the control unit (60) of the home appliance (1). Alternatively, for example, the motor driver can be electrically connected to the sensor (200), and the door opening device (100) can operate based on an output signal received from the sensor (200).

[0135] Although not clearly shown in the drawing, the power unit (130) may be supported by the pusher case (110). The power unit (130) may be accommodated inside the pusher case (110).

[0136] The door opening device (100) may further include a power transmission member (not shown) provided to transmit power generated by the power unit (130) to the door pusher (120).

[0137] The power transmission member can be supported by the pusher case (110). The power transmission member can be accommodated inside the pusher case (110).

[0138] A refrigerator (1a) according to one embodiment of the present disclosure may include a gasket (39). The gasket (39) may be positioned on the side of the door (30) facing the storage compartment (20). The gasket (39) may be positioned on the back surface (31) of the door (30). The gasket (39) may extend along the edge of the back surface (31) of the door (30). For example, the gasket (39) may include a roughly square ring shape.

[0139] The gasket (39) can maintain a seal between the door (30) and the main body (10) while the door (30) closes the storage room (20). The gasket (39) can be in close contact with the main body (10) while the door (30) closes the storage room (20). The gasket (39) can maintain a distance greater than a predetermined distance between the door (30) and the main body (10) while the door (30) closes the storage room (20). The gasket (39) can prevent cold air inside the storage room (20) from leaking out.

[0140] A refrigerator (1a) according to one embodiment of the present disclosure may include a sensor (200). The sensor (200) may receive a door opening signal. The sensor (200) may receive an open trigger. The open trigger may include a user's push action. Specifically, the open trigger may include a user pushing the door (30) with a force greater than a predetermined amount.

[0141] The sensor (200) may be configured to measure force. The sensor (200) may be configured to detect a force acting on the sensor (200). The sensor (200) may be configured to detect a force pressing on the sensor (200). The sensor (200) may be configured to detect a physical force applied to the sensor (200). The sensor (200) may be configured to detect pressure applied to the sensor (200). The sensor (200) may be configured to detect a force generated as a user pushes the door (30). The sensor (200) may be configured to detect a force generated as a user presses the door (30). For example, the sensor (200) may include a force sensor. The description of the sensor (200) may be a description common to examples of the sensor (200a, 200b, 200c). That is, the description of the sensor (200) described above or below can be applied to each of the examples of the sensor (200a, 200b, 200c).

[0142] Referring to FIGS. 2 to 5, an example (200a) of a sensor (200) will be described.

[0143] The sensor (200a) may be provided in the main body (10). The sensor (200a) may be mounted on the main body (10). The sensor (200a) may be installed on the main body (10).

[0144] The sensor (200a) may be positioned on the main body (10) to correspond to the gasket (39). The sensor (200a) may be positioned to face the gasket (39) while the door (30) closes the storage room (20). The sensor (200a) may be arranged to contact the gasket (39) while the door (30) closes the storage room (20). When the door (30) closes the storage room (20), the sensor (200a) may be positioned to make contact with the gasket (39). For example, the sensor (200a) may be positioned on the front edge (10a) of the main body (10). For example, the front edge (10a) of the main body (10) is a part that can come into contact with the gasket (39), so that when the door (30) is closed, the gasket (39) can be in close contact with the front edge (10a) of the main body (10). For example, the front edge (10a) of the main body (10) may include the front of the inner body (11).

[0145] The sensor (200a) can detect the force applied from the gasket (39) to the sensor (200a) while the door (30) closes the storage room (20). The sensor (200a) can detect the force received from the gasket (39) while the door (30) closes the storage room (20). The force detected by the sensor (200a) may include the force generated as the door (30) is pressed by a user. The user may push the door (30) while the storage room (20) is closed, and the force applied to the door (30) may be transmitted to the sensor (200a) through the gasket (39). When pressure is applied to the door (30), the gasket (39) is compressed, and the compressed gasket (39) may transmit pressure to the sensor (200a). When the user presses the door (30) with a force greater than a predetermined amount, the sensor (200a) can detect an open trigger. The user can convey the intention to open the door to the home appliance (1) by pressing the door (30).

[0146] According to one embodiment of the present disclosure, the sensor (200a) may be positioned spaced apart from the hinge (40). The sensor (200a) may be positioned away from the hinge (40). For example, the sensor (200a) may be positioned close to the center with respect to the front of the main body (10). The door (30) may rotate relative to the main body (10) with respect to the hinge (40). Accordingly, when a user pushes the door (30), the gasket (39) may have a compression rate greater on the side farther from the hinge (40) than on the side closer to the hinge (40). That is, compared to the case where the sensor (200a) is positioned on the side closer to the hinge (40), the sensor (200a) may react more sensitively when the sensor (200a) is positioned on the side farther from the hinge (40). That is, the sensitivity of the sensor (200a) may be relatively excellent. However, the above-described embodiment is merely exemplary, and it is sufficient for the sensor (200a) to be positioned so as to come into contact with the gasket (39), and there are no restrictions on the position of the sensor (200a).

[0147] For example, the gasket (39) may include a first extension (391) that is adjacent to the hinge (40) and extends in the vertical direction (Z). The gasket (39) may include a second extension (392) that is provided on the opposite side of the first extension (391) and extends in the vertical direction (Z). The first extension (391) and the second extension (392) may be configured to be parallel. The gasket (39) may include a third extension (393) that connects the upper side of the first extension (391) and the upper side of the second extension (392). The third extension (393) may extend in the horizontal direction (Y). The gasket (39) may include a fourth extension (394) that connects the lower side of the first extension (391) and the lower side of the second extension (392). The fourth extension (394) may be extended in the horizontal direction (Y). The third extension (393) and the fourth extension (394) may be configured to be parallel.

[0148] For example, the sensor (200a) may come into contact with a part of the second extension (392) while the door (30) closes the storage room (20) (see FIG. 4 and FIG. 5). For example, the sensor (200a) may be positioned to correspond to a corner where the third extension (393) and the second extension (392) are connected (or overlapped) (see FIG. 4). For example, the entire sensor (200a) may be positioned to correspond to the second extension (392) (see FIG. 5). As described above, the sensor (200a) may be positioned on a side relatively far from the hinge (40). However, as described above, the present disclosure is not limited to the above examples.

[0149] FIG. 6 is a plan view illustrating an example of a first state in which the door is closed in a refrigerator according to one embodiment of the present disclosure. FIG. 7 is a plan view illustrating an example of a second state in which the door is pressed in a refrigerator according to one embodiment of the present disclosure. FIG. 8 is a plan view illustrating an example of a third state in which the door is open in a refrigerator according to one embodiment of the present disclosure.

[0150] Referring to FIG. 6, the refrigerator (1a) may be provided in a first state (S1) in which the door (30) closes the storage room (20). The back side (31) of the door (30) may be provided to face the storage room (20). The back side (31) of the door (30) may be provided to face the front of the main body (10). At least a portion of the rotating bar (50) may be inserted into the rotating guide (55). A gasket (39) may be provided to seal the space between the main body (10) and the door (30).

[0151] When the door (30) is in a first state (S1) of closing the storage room (20), the sensor (200a) may be arranged to face the gasket (39). When the door (30) is in a first state (S1) of closing the storage room (20), the sensor (200a) may be arranged to be able to contact the gasket (39). While the door (30) is in a first state (S1) of closing the storage room (20), the gasket (39) may have a first thickness (t1).

[0152] Referring to FIG. 7, the refrigerator (1a) may be provided in a second state (S2) in which the door (30) is pressed. The second state (S2) may mean a state in which the door (30) is pressed in the first state (S1). That is, the second state (S2) may mean a state in which the door (30) is pressed while closing the storage room (20). The user may push the closed door (30) with a force (F) greater than a predetermined amount.

[0153] When the door (30) is in a second state (S2) where it is pressurized, the gasket (39) is compressed, and the compressed gasket (39) can press against the sensor (200a). The force (F) acting on the door (30) can be transmitted to the sensor (200a) through the gasket (39). The sensor (200a) can detect the physical force / pressure applied to the sensor (200a) from the gasket (39). While the door (30) is in the second state (S2) where it is pressurized, the gasket (39) may have a second thickness (t2). Since the gasket (39) is compressed by the force (F) applied to the door (30), the second thickness (t2) is smaller than the first thickness (t1).

[0154] Referring to FIG. 8, the refrigerator (1a) may be provided in a third state (S3) in which the door (30) opens the storage compartment (20). In the second state (S2) in which the door (30) is pressed, the door opening device (100) may operate to open the door (30) based on the sensor (200a) detecting an open trigger. When a user presses the closed door (30) with a force (F) greater than a predetermined amount, the door opening device (100) may operate to open the door (30). To open the door (30), the door pusher (120) of the door opening device (100) may press the door (30) by moving (M). The door pusher (120) may protrude forward. The door (30), pressed by the door pusher (120), can rotate (R) relative to the main body (10) with respect to the hinge (40). The front of the main body (10) and the back (31) of the door (30) can be arranged to form an angle. The rotation bar (50) can be disengaged from the rotation guide (55). The sensor (200a) may not come into contact with the gasket (39).

[0155] Generally, home appliances can open doors by directly touching a sensor or by providing vibration to the sensor. However, in such cases, there is a limitation in that the sensing area is restricted because the user must touch or tap a limited area. Alternatively, the door can be opened by triggering voice into a microphone. However, this is not an intuitive method, so the user may feel inconvenienced.

[0156] According to the present disclosure, the entire door (30) can be used as a sensing area, thereby increasing the sensing area. The user only needs to push the door (30) without needing to recognize the sensing area. Additionally, the user can directly convey the intention to open the door to the home appliance through the act of directly pushing the door (30). That is, the user can provide a user command to open the door (30) to the home appliance in an intuitive manner. Ultimately, according to the present disclosure, the convenience of use of the home appliance can be increased.

[0157] FIG. 9 illustrates a sensor according to one embodiment of the present disclosure.

[0158] Referring to FIG. 9, a sensor (200) according to one embodiment of the present disclosure may include a capacitance sensor configured to detect a change in capacitance. A door opening signal may be generated when a user pushes the door (30), and the sensor (200) may generate an output signal and / or an output value based on a change in capacitance according to the door opening signal.

[0159] The sensor (200) may include a first conductive plate (210). The sensor (200) may include a second conductive plate (220) spaced apart from the first conductive plate (210).

[0190] According to one embodiment of the present disclosure, the control unit (60) can control the door opening device (100) to open the door (30) based on the detection of a preset condition by the first sensor (200). For example, the control unit (60) can control the door opening device (100) to open the door (30) based on the fact that the value detected by the first sensor (200) is greater than a reference value (R, see FIG. 11). For example, the control unit (60) can identify an open trigger based on a signal and / or data received from the first sensor (200), and can transmit a control signal to the door opening device (100) to open the door (30) in response to the identification of the open trigger. Meanwhile, the control unit (60) can perform the above-described operation after identifying that the door (30) is in a state of closing the storage room (20). For example, the control unit (60) can determine that the door (30) is in a closed state based on information obtained by the second sensor (300), and then control the door opening device (100) to open the door (30) based on information obtained by the first sensor (200).

[0191] According to one embodiment of the present disclosure, a door opening device (100) may operate based on information obtained by a first sensor (200).

A user may recognize that the door (30) has been opened through the external device even when far away from the home appliance (1).

[0194] A home appliance (1) according to one embodiment of the present disclosure may not include some of the components shown in FIG. 10. A home appliance (1) according to one embodiment of the present disclosure may include additional components other than those shown in FIG. 10.

[0195] FIG. 11 is a graph showing the sensor output of a sensor according to one embodiment of the present disclosure.

[0196] Referring to FIG. 11, the sensor (200) can detect physical force / pressure and convert it into an output signal. FIG. 11 illustrates the sensor output as a digital signal (count) as an example, but the present disclosure is not limited thereto. The sensor output may be an analog signal.

[0197] FIG. 11 schematically illustrates an example in which a door (30) closes the storage room (20) for a first preset time (a), and then a user pushes the closed door (30) for a second preset time (b).

[0198] The sensor (200) can detect an open trigger. For example, an open trigger may be generated when a user pushes the door (30) with a force greater than a predetermined amount. For example, if the value (output signal) detected by the sensor (200) is greater than a reference value (R), it can be considered that an open trigger has occurred. That is, for example, if the value (output signal) detected by the sensor (200) is greater than the reference value (R), it can be recognized that an intention to open the door (30) has been input.

[0199] For example, the reference value (R) may be a preset multiple of the base value (B). For example, the reference value (R) may be an n-th multiple of the base value (B). The base value (B) may be the average of the values ​​detected by the sensor (200) during a first preset time (a) while the door (30) is closing the storage room (20). The base value (B) may be updated at a third preset time interval. This is to compensate for the change in the initial setting value of the sensor (200) as the door (30) opens and closes.

[0200] FIG. 12 is a flowchart illustrating a method for controlling a home appliance according to one embodiment of the present disclosure.

[0201] The symbols attached to each step are used to identify each step and do not indicate the order of the steps relative to one another; the steps may be performed differently from the specified order unless a specific order is clearly indicated in the context.

The second sensor (300) can transmit information regarding the opening or closing of the door (30) to the control unit (60) and / or the door opening device (100).

[0203] The home appliance (1) can recognize whether the door (30) is in a closed state based on the open / close information of the door (30) received from the second sensor (300) (2000). The control unit (60) and / or the door opening device (100) can determine whether the door (30) is in a closed state based on the open / close information of the door (30) transmitted from the second sensor (300).

[0204] When the home appliance (1) recognizes that the door (30) is in a closed state, it can obtain detection information detected by the first sensor (200). The first sensor (200) can detect a force applied to the first sensor (200) and transmit information corresponding to the detected force to the control unit (60) and / or the door opening device (100).

[0205] The home appliance (1) can control the door opening device (100) to open the door (30) based on the satisfaction of a predetermined condition. The home appliance (1) can control the door opening device (100) to open the door (30) based on the detection of an open trigger (e.g., 3000) (4000). Specifically, an open trigger may occur when a user pushes the door (30) with a force greater than a predetermined size, and the first sensor (200) can detect the open trigger. For example, the control unit (60) can control the door opening device (100) to open the door (30) based on the detection of an open trigger by the first sensor (200). Alternatively, the door opening device (100) can operate to open the door (30) in response to the detection of an open trigger by the first sensor (200). For example, an open trigger detected by the first sensor (200) may include cases where the value detected by the first sensor (200) is greater than a reference value (R, FIG. 11).
