Definitions
- the present invention relates to a new type of refrigerator capable of accurately determining a door opening request by a user and automatically opening the door.
- a refrigerator is a home appliance that uses cold air to store stored items for a long time.
- a refrigerator provides at least one or more storage compartments in which stored items are stored, and the storage compartment is opened and closed by a door.
- the door may be unintentionally opened by a user or a pet passing by.
- the user cannot adjust the touch sensitivity or the like. That is, when a sensor or switch is located in a cabinet of a refrigerator, it is difficult to set a detailed level of detection that may be sensitive depending on an installation environment. As a result, the door is opened frequently regardless of the user's intention.
- a sensor or switch for confirming the door opening request is located in the cabinet. Accordingly, when a failure of the sensor or switch occurs, there is a problem in that work to repair it is inevitably difficult.
- the present invention was made to solve various problems according to the prior art described above.
- an object of the present invention for this purpose, it is to ensure that a user's request to open a door is accurately confirmed. Accordingly, it is possible to solve the problem that the door is opened while the device for automatically opening the door is operated undesirably.
- it is to enable a user to easily set a desired level of operating force. In this way, it is possible to differently set the request to open the door, which may be different for each user.
- it is to facilitate repair or maintenance of a structure for confirming a door opening request or a device. Accordingly, even if a failure of the sensor or switch occurs, the sensor or switch can be easily replaced without disassembling the cabinet.

- a sensor may be provided on the door to detect a request to open the door.
- the sensing unit may be configured to sense that the door is pressed toward the cabinet. Accordingly, it is possible to determine that opening of the door has been requested when an operation to press the door occurs.
- the sensing unit may be mounted to be received from the surface of the door. As a result, external exposure can be minimized and damage or the like can be prevented.
- the sensing unit may be mounted on a surface of the door facing the cabinet.
- the sensing unit may be mounted on any one circumferential surface of the door.
- the sensing unit may include a pressing member that moves in the opposite direction to the cabinet when the door is pressed. Accordingly, whether or not the door is automatically opened may be differently determined according to the pressing amount of the door. That is, when pressing the door exceeding the set pressing amount, an operation control or operation for automatically opening the door may be performed.
- the sensing unit may be configured to sense the movement of the pressing member when the door is pressed. Accordingly, an operation control or an operation for automatically opening the door may be selectively performed according to the pressing amount of the door.
- the sensing unit may be provided in the mounting groove.
- the sensing unit may include a member for detecting movement of the pressing member when the door is pressed.
- the sensing member may be composed of at least one of a sensor or a switch.
- the sensing member may be disposed in the moving path of the pressing member.
- the pressing member may include a pressing end that presses while contacting the cabinet when the door is pressed.
- the pressing member may include a contact end extending in a moving direction of the pressing end.
- the contact end may be configured to selectively contact the sensing member or to press the sensing member. That is, it may be determined that the door opening request has been made when the contact end contacts the sensing member, or it may be determined that the door opening request has been made when the contact end presses the sensing member.
- the pressing end may be formed to make surface contact with the cabinet. In this way, the pressing member can be accurately moved toward the opposite direction to the cabinet.

- the specific part is a part where the sensing unit 300 is located, and in case of referring to the embodiment of the present invention, it may be a lower left corner of the front surface of the door 200.
- the gasket member 210 is compressed by the corresponding pressing force, and the opposite surfaces between the door 200 and the cabinet 100 come into close contact with each other.
- the entire door 200 is pushed back and the gasket member 210 is compressed so that the opposite surfaces between the door 200 and the cabinet 100 are adjacent to each other. it gets done
- the pressing member 320 of the sensing unit 300 contacts or presses the sensing member 310 while moving in the direction where the sensing member 310 is positioned by the adjacent distance. This is the same as the attached figure 9.
- the sensing member 310 senses the user's operation (occurrence of a request to open the door) by the contact or pressurization of the pressing member 320, and the operation of the door opening part 400 by the detected signal. Section 420 is operated.
- the pushing member 410 of the door opening unit 400 pushes the door 200 in contact with the door 200 in the opening direction, and thus the door 200 moves to the pushing member 410. is opened as much as the operating distance of This is the same as the attached Figures 10 to 13.
- the user can easily open the opened door 200 as described above even when both hands are not free.
- the pressing member 320 of the sensing unit 300 is separated from the sensing member 310 by the restoring force of the restoring member 330, and thus the operating unit 420 of the door opening unit 400 ) will stop the operation.
- the user may directly adjust the operating force (degree of pressing the door, pressing force of the door) required by the sensing unit 300 for sensing. That is, the required operating force is adjusted by adjusting the protruding distance of the contact end 322 from the pressing end 321 constituting the pressing member 320 of the sensing unit 300 .
- the sensing member 310 can easily recognize whether the door 200 is pressed even with a small operating force. Conversely, as the contact end 322 is inserted into the pressing end 321, the operating force required for the sensing member 310 to recognize increases.
- the sensing unit 300 may be separated from the door 200 . Then, after separating the lower case 342 from the upper case 341, the contact end 322 constituting the pressing member 320 is further protruded from the pressing end 321 or further inserted.
- the refrigerator of the present invention is configured to confirm a user's request to open the door 200 when a specific portion of the door 200 is pressurized above a set pressure. As a result, the problem of unwanted opening of the door 200 may be solved.
- the operating force (door pressing force) desired by the user can be easily set by manipulating the protruding distance of the contact end 322 from the pressing end 321 .
- the senor 300 is provided on the door 200 and is provided at a position where a user (or operator) can easily separate it, adjustment or maintenance of the operating force (door pressing force) can be easily performed. . That is, the sensing member 320 can be replaced or the operating force can be adjusted without disassembling the cabinet 100 .
- the refrigerator of the present invention may be implemented in various forms different from the structure of the above-described embodiment.
- the sensing unit 300 may be mounted in a structure protruding from the surface of the door 200 rather than being disposed concavely mounted into the surface of the door 200 .
- the sensing unit 300 may be provided on the lower surface of the door 200 .
- the adjustment of the operating force of the sensing unit 300 may be configured to be performed by adjusting the front and rear position of the sensing member 310 . That is, by configuring the sensing member 310 to be able to adjust the forward and backward position within the case 340, the operating force for confirming the opening request of the door 200 can be adjusted.
- control of the operating force of the sensing unit 300 may be configured to be performed by selectively using a plurality of restoring members 330 having different elasticity.
- the refrigerator of the present invention may be implemented by variously modifying the position or number of the sensing units 300 or the structure for adjusting the operating force.
