Description

Technical Field

[0001] This utility model relates to the technical field of household appliances, specifically to a hub sensor for opening and closing doors and a refrigerator. Background Technology

[0002] Appliances with doors (such as refrigerators) are typically programmed with corresponding instructions based on the door's opening and closing status for user convenience (e.g., opening the refrigerator door turns on the light, closing it turns off the light). Generally, these appliances require an internal switch mechanism that operates in conjunction with the door. However, the internal environment of the appliance (e.g., the low temperature and high humidity inside a refrigerator) can negatively impact the lifespan and reliability of this switch mechanism.

[0003] Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a hub sensor for opening and closing doors. It can be installed on the outside of electrical equipment and generate electrical signals in conjunction with the door, thereby reducing the impact of the internal environment of the electrical equipment on the hub sensor, extending the service life of the hub sensor, and improving the reliability of the hub sensor.

[0005] The purpose of this utility model is achieved as follows: A hub sensor for opening and closing a door includes a movable component and a main body that can be installed on the outside of the door. The movable component is provided with a sensing element and a linkage component for linkage with the door to cause the movable component to drive the sensing element to rotate.

[0018] Figure 3 This is a cross-sectional schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] See Figures 1-3The hub sensor used in this door opening and closing mechanism includes a movable part 1 and a main body 2 that can be installed on the outside of the door (not shown in the figure). The movable part 1 is equipped with a sensing element 3 and a linkage part 4 for linkage with the door to make the movable part 1 drive the sensing element 3 to rotate. The main body 2 is equipped with a detection module 5 that can generate an electrical signal through the rotation of the sensing element 3. The hub sensor can be set on the outside of the electrical equipment and generate an electrical signal in linkage with the door, which reduces the impact of the internal environment of the electrical equipment on the hub sensor, extends the service life of the hub sensor, and improves the reliability of the hub sensor.

[0021] The sensing element 3 and the detection module 5 can be a light signal emitting element and a light signal receiving module, respectively. The specific principle is that the light signal emitted by the light signal emitting element is irradiated onto the light signal receiving module by the light signal emitting element through its rotation, thereby causing the light signal receiving module to generate an electrical signal.

[0022] Alternatively, the sensing element 3 and the detection module 5 can be a magnet and a Hall effect sensor module, respectively. During its rotation, the magnet generates a changing magnetic field on the Hall effect sensor module, ultimately forming a Hall voltage to produce an electrical signal. The electrical equipment can then issue different operating commands based on these different electrical signals. The Hall effect sensor module is a conventional magnetoelectric conversion sensor, and its specific structure and working principle are easily understood by those skilled in the art.

[0023] Furthermore, the linkage 4 is in the shape of a long rope. The two ends of the linkage 4 are connected and fixed to the movable part 1 and the door body respectively. The middle section of the linkage 4 is coiled around the outer wall of the movable part 1. The sensing element 3 is set at the center of the movable part 1. The detection module 5 is set on the main body 2 at the position corresponding to the outer side of the sensing element 3. The door body can pull the movable part 1 and the sensing element 3 to make a forward rotation through the linkage 4.

[0024] Furthermore, the outer side wall of the movable part 1 is provided with a limiting groove 11 corresponding to the linkage part 4, which has a limiting effect on the linkage part 4, preventing the linkage part 4 from being misaligned on the surface of the movable part 1, thus preventing the movable part 1 from being pulled to rotate normally.

[0025] Furthermore, the movable part 1 has a protruding post 12 at its center position, and the sensing element 3 is installed and fixed at the inner center position of the protruding post 12. The main body 2 has a groove 21 corresponding to the protruding post 12. The protruding post 12 and the groove 21 are matched for limiting. The protruding post 12 can not only fix and position the sensing element 3, but also cooperate with the groove 21 to improve the stability of the movable part 1 when it rotates.

[0026] Furthermore, the outer side of the movable part 1 is provided with a circumferentially oriented limiting protrusion 13, and the main body 2 is provided with a limiting groove 24 corresponding to the limiting protrusion 13. The limiting protrusion 13 and the limiting groove 24 are matched in a limiting manner, which can further improve the stability of the movable part 1 when it rotates.

[0027] Furthermore, a reset component 6 is connected between the movable component 1 and the main body 2. The reset component 6 can pull the movable component 1 and the sensing element 3 to rotate in opposite directions. The reset component 6 is a coil spring. The movable component 1 is provided with an inner cavity 14 corresponding to the coil spring. The first end of the coil spring is located at the center of the spiral and is connected and fixed to the main body 2. The tail end of the coil spring is connected and fixed to the movable component 1, so that the movable component 1 can automatically reset, simplifying the operation difficulty.

[0028] Furthermore, the sidewall of the inner cavity 14 is provided with several limiting ribs 141 distributed circumferentially. The limiting ribs 141 are adjacent to and cooperate with the outer side of the coil spring. The limiting ribs 141 can not only improve the structural strength of the moving part 1, but also prevent the coil spring from being damaged due to excessive rebound amplitude during the reset process.

[0029] Furthermore, the main body 2 includes an upper shell 22 and a lower shell 23. The upper shell 22 and the lower shell 23 are closed to form a cavity for installing the movable part 1. The upper shell 22 and the lower shell 23 are connected and fixed by a snap-fit ​​structure, which makes the overall assembly of the hub sensor easier and improves assembly efficiency.

[0030] Furthermore, a connector 7 is provided on the outside of the main body 2. The connector 7 is electrically connected to the detection module 5 through a wire harness. The hub sensor can be connected to the control module of the electrical equipment through the connector 7.

[0031] This utility model also discloses a refrigerator, including a cabinet (not shown in the figure), a door, and a hub sensor for opening and closing the door. The main body 2 is connected and fixed to the outside of the cabinet, and the linkage 4 is connected and fixed to the outside of the door, so that the hub sensor is not affected by the low temperature and humidity inside the refrigerator, thus extending its service life and improving its reliability.

[0032] When the user opens or closes the door, the door moves and drives the linkage 4 to move. The linkage 4 drives the moving part 1 and the sensing element 3 to rotate synchronously. The detection module 5 senses the change in magnetic field and generates an electrical signal. After receiving the electrical signal, the refrigerator's control system will issue a corresponding command to open or close the door (such as turning the light on or off).

[0033] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
