Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and in particular to a refrigerator baseboard and a refrigerator. Background Technology

[0002] With the rapid development of smart home technology, refrigerators, as a common household appliance, are constantly improving their level of intelligence. Fully automatic refrigerators, by integrating sensors, cameras, and other detection devices, can detect whether there is someone in front of the refrigerator while automatically opening and closing the door, and can pause the closing action when someone is detected, thereby effectively preventing safety hazards such as pinched fingers.

[0003] In existing technologies, sensors or cameras are typically integrated directly into the refrigerator door to detect the presence of someone in front of the refrigerator. However, because the refrigerator door shifts during opening and closing, the integrated sensors or cameras move synchronously with the door when it opens, causing their detection area to shift. Since the detection device's field of view changes with the door's opening angle, it may not be able to stabilize the area in front of the user standing. Therefore, the system may incorrectly determine that no one is in front and continue closing the door, resulting in low reliability of the anti-pinch function and negatively impacting the user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a refrigerator baseboard that can solve the above problems.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A refrigerator baseboard is used for installation on the refrigerator body and is positioned below the refrigerator door along the height direction of the refrigerator. The refrigerator baseboard includes:

[0007] Baseboard, used for installation on the enclosure;

[0008] The detection component is installed on the side of the baseboard facing the refrigerator body and is connected to the external refrigerator door switch unit. The detection component can control the refrigerator door switch unit to perform corresponding actions based on whether there is interference in front of the refrigerator door.

[0009] Understandably, this application utilizes a detection element installed on the baseboard to detect any interference in front of the refrigerator. When interference is detected, a signal is sent to the refrigerator door opening / closing unit, causing it to perform a corresponding action, namely, stopping the door from closing. Since the detection element is mounted on the baseboard, which is located on the refrigerator body, the relative position of the detection element and the body is fixed. Therefore, the detection range does not change with the opening / closing of the refrigerator door, accurately detecting whether someone is in front of the refrigerator. This allows for precise control of the refrigerator door opening / closing unit to stop the door from closing. The detection element also provides high reliability for the anti-pinch function, improving the user experience.

[0010] In one embodiment, the detection element is configured as a lidar.

[0011] Understandably, by configuring the detection device as a lidar, it is possible to accurately determine whether there is a person in front of the refrigerator and continuously detect the person's location. Moreover, this detection is not affected by environmental factors such as strong light or dark environments, electromagnetic interference from other electrical appliances, or dust, thus ensuring the accuracy of detecting whether there is a person in front of the refrigerator.

[0012] In one embodiment, the angle between the lidar and the horizontal plane is α, where 30° ≤ α ≤ 60°.

[0013] Understandably, by limiting the angle to 30°≤a≤60°, the detection range of the lidar can cover the area in front of the refrigerator where people may appear, improving the effectiveness and accuracy of detection, ensuring that people or objects in front of the refrigerator door can be detected in a timely manner, thereby better controlling the refrigerator door to stop closing.

[0014] In one embodiment, the detection element is disposed at the bottom of the baseboard along the height direction of the refrigerator and at the middle position of the baseboard along the width direction of the refrigerator.

[0015] Understandably, by placing the detection device at the bottom of the baseboard along the height of the refrigerator and in the middle along the width of the refrigerator, the detection range can be optimized, thereby promptly detecting the approach of people and controlling the opening and closing of the refrigerator door, effectively preventing fingers from being pinched.

[0016] In one embodiment, the refrigerator baseboard further includes a mounting member, through which the detection member is mounted to the baseboard.

[0017] Understandably, by using mounting brackets, the testing component is installed on the baseboard, making the installation process more convenient and allowing for more precise fixation in the appropriate position. Simultaneously, it facilitates disassembly and replacement when the testing component malfunctions or requires maintenance, reducing repair costs and complexity.

[0018] In one embodiment, the mounting component is connected to the side of the skirting board facing the box body, and includes a positioning plate, a buckle and a limiting rib. The positioning plate and the buckle are spaced apart along the circumference of the detection component to limit the circumference of the detection component.

[0019] Along the height direction of the refrigerator, the positioning plates and / or the buckles at both ends of the detection component are provided with limiting ribs facing the detection component. The buckles and the limiting ribs respectively limit the two sides of the detection component, so that the detection component is at a preset angle with the horizontal plane.

[0020] In one embodiment, the mounting component includes a mounting plate and a placement plate. The mounting plate is mounted on the side of the skirting board facing the housing. The placement plate is connected to the mounting plate and is set at a preset angle to the horizontal plane to load the detection component and make the detection component at a preset angle to the horizontal plane.

[0021] The placement plate is provided with a snap-fit ​​part, and the detection component snaps into and limits the position of the snap-fit ​​part.

[0022] In one embodiment, the baseboard is configured to be made of plastic.

[0023] This application also provides the following technical solutions:

[0024] A refrigerator includes a refrigerator baseboard and a refrigerator door opening and closing unit as described in any of the above embodiments.

[0025] In one embodiment, the refrigerator has a wiring assembly disposed at the bottom of the refrigerator body and electrically connected to the detection element.

[0026] Compared to existing technologies, this refrigerator kickboard utilizes a detection element mounted on the kickboard plate to detect any interference in front of the refrigerator. When interference is detected, a signal is sent to the refrigerator door opening / closing unit, causing it to stop the door from closing. Because the detection element is mounted on the kickboard plate, which is located on the refrigerator body, the relative position of the detection element and the body is fixed. Therefore, the detection range does not change with the opening / closing of the refrigerator door, accurately detecting the presence of anyone in front of the refrigerator and precisely controlling the door opening / closing unit to stop the door from closing. The detection element also provides high reliability for the anti-pinch function, improving the user experience. Attached Figure Description

[0040] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0041] Please see Figures 1 to 6 This application provides a refrigerator kickboard 100, which is used to install on the refrigerator body and is located below the refrigerator door along the height direction z of the refrigerator. It can protect the body and make the refrigerator more aesthetically pleasing. In addition, the refrigerator kickboard 100 can also detect whether there is someone in front of the refrigerator. When there is someone in front of the refrigerator and the refrigerator door is closing, the refrigerator kickboard 100 can transmit a signal to the refrigerator door opening and closing unit and stop the refrigerator door from closing.

[0042] Specifically, the refrigerator kickboard 100 includes a kickboard plate 10 and a detection element 20. The kickboard plate 10 is installed on the refrigerator body; the detection element 20 is installed on the side of the kickboard plate 10 facing the refrigerator body and is signal-connected to the external refrigerator door opening and closing unit. The detection element 20 can control the refrigerator door opening and closing unit to perform corresponding actions based on whether there is interference in front of the refrigerator door. Thus, this application, by setting the detection element 20 on the kickboard plate 10, uses the detection element 20 to detect whether there is interference in front of the refrigerator. When interference is detected, it outputs a signal to the refrigerator door opening and closing unit, causing it to perform a corresponding action, namely, stopping the door from closing. Since the detection element 20 is set on the kickboard plate 10, and the kickboard plate 10 is set on the refrigerator body, the relative position of the detection element 20 and the body is fixed. Therefore, the detection range does not change with the opening / closing of the refrigerator door, and it can accurately detect whether there is someone in front of the refrigerator, thereby accurately controlling the refrigerator door opening and closing unit to stop the door from closing. The detection element 20 has high reliability in detecting the anti-pinch function, which can improve the user experience.

[0043] In one embodiment, the detection element 20 is configured as a lidar. It should be noted that in other embodiments, the detection element 20 may also be configured as an ultrasonic sensor, infrared sensor, etc., but since lidar has the best detection effect, it is used in this embodiment. Thus, by configuring the detection element 20 as a lidar, it is possible to accurately determine whether there is a person in front of the refrigerator and continuously detect the person's location. This detection is unaffected by strong light or darkness, electromagnetic interference from other electrical appliances, dust, or other environmental factors, thereby ensuring the accuracy of detecting whether there is a person in front of the refrigerator.

[0044] like Figure 1 , Figure 4 and Figure 6 As shown, the angle between the lidar and the horizontal plane is 'a', where 30° ≤ a ≤ 60°. For example, a = 30°, a = 40°, a = 45°, a = 50°, a = 60°, etc. can be selected. Figure 6 As shown, in practical use, the detection range of the lidar is d=120°. Since the ground being too close to the baseboard will interfere with the radar's detection, the microwave radar needs to be tilted upwards. By limiting the angle to 30°≤a≤60°, the lidar's detection range can cover the area in front of the refrigerator where people may appear, improving the effectiveness and accuracy of detection. This ensures that people or objects in front of the refrigerator door can be detected in a timely manner, thereby better controlling the refrigerator door to stop closing.

[0045] Preferably, the angle between the lidar and the horizontal plane is selected as α = 30°. When α = 30°, the lowest detection angle of the microwave radar is exactly parallel to the ground, which can avoid ground interference.

[0046] Furthermore, the detection element 20 is positioned at the bottom of the baseboard 10 along the height direction z of the refrigerator, and at the middle position of the baseboard 10 along the width direction x of the refrigerator. Thus, by positioning the detection element 20 at the bottom of the baseboard 10 along the height direction z and at the middle position along the width direction x, the detection range is optimized, allowing for timely detection of personnel approaching and control of the refrigerator door opening and closing, effectively preventing hand pinching.

[0047] like Figure 2 , Figure 3 and Figure 5 As shown, the refrigerator baseboard 100 also includes a mounting bracket 30, through which the detection component 20 is mounted to the baseboard 10. By providing the mounting bracket 30, the detection component 20 is mounted to the baseboard 10, making the installation process of the detection component 20 more convenient and allowing for more precise fixing in the appropriate position. Simultaneously, when the detection component 20 malfunctions or requires maintenance, it is also easier to disassemble and replace, reducing maintenance costs and difficulty.

[0048] like Figure 2 and Figure 3 As shown, the mounting component 30 is connected to the side of the baseboard 10 facing the cabinet and includes a positioning plate 31, a buckle 32, and a limiting rib 33. The positioning plate 31 and the buckle 32 are spaced apart circumferentially along the detection component 20 to limit the detection component 20 circumferentially. Along the height direction z of the refrigerator, the positioning plate 31 and / or the buckle 32 at both ends of the detection component 20 have limiting ribs 33 facing the detection component 20. The buckle 32 and the limiting ribs 33 limit the two sides of the detection component 20 respectively, so that the detection component 20 is at a preset angle with the horizontal plane. Here, there can be multiple buckles 32, such as two, three, four, etc., and there can be multiple limiting ribs 33, such as four, five, six, seven, eight, etc. The limiting ribs 33 can be elongated protrusions, circular protrusions, or other shapes that can limit the detection component 20.

[0049] In one embodiment, two positioning plates 31 are configured and located at two opposite corners of the detection element 20, which is positioned by the positioning plates 31. Two latches 32 are configured and located at both ends of the refrigerator's width direction x, with the side of the detection element 20 away from the baseboard 10 being limited by the two latches 32. Six limiting ribs 33 are configured and located on the positioning plates 31 and / or latches 32 at both ends of the refrigerator's height direction z, with the three upper limiting ribs 33 being longer than the three lower limiting ribs 33, so that the detection element 20 is tilted relative to the horizontal plane and the side emitting microwaves is positioned close to the baseboard 10 and tilted upwards, thereby making the detection range of the microwave radar the front area of ​​the refrigerator.

[0050] like Figure 5As shown, in another embodiment, the mounting component 30 includes a mounting plate 34 and a placement plate 35. The mounting plate 34 is mounted on the side of the baseboard 10 facing the housing. The placement plate 35 is connected to the mounting plate 34 and is set at a preset angle to the horizontal plane, used to load the detection component 20 and make the detection component 20 at a preset angle to the horizontal plane. The placement plate 35 is provided with a snap-fit ​​part 351, which snaps and limits the detection component 20. Here, the mounting plate 34 and the baseboard 10 can be fixed by threaded connection, snap-fit, etc., and the mounting plate 34 and the placement plate 35 can be connected by snap-fit ​​32, threaded connection, welding, or integral molding.

[0051] In one embodiment, the skirting board 10 is made of plastic. Since the frequency of microwave radar is 24 GHz, and the molecular structure and micro-gap inside the plastic part are relatively large compared to the wavelength of 24 GHz microwaves, microwaves can bypass these micro-structures and continue to propagate. Therefore, when the skirting board 10 is made of plastic, it will not affect the detection of microwave radar.

[0052] This application also provides the following technical solutions:

[0053] A refrigerator includes a refrigerator baseboard 100 and a refrigerator door switch unit as described in any of the above embodiments.

[0054] In one embodiment, the refrigerator has a wiring assembly located at the bottom of the refrigerator body and electrically connected to the detection element 20. The other end of the wiring assembly can be electrically connected to a power source, thereby supplying power to the detection element 20. Furthermore, the other end of the wiring assembly can also be a refrigerator door switch unit or a display unit, etc., to control the refrigerator door to stop closing.

[0055] The smart appliance carrying the detection element 20 has a smart voice control module, which includes a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the detection element 20 to perform corresponding operations, thereby realizing the intelligent control of the detection element 20 and improving the user experience of using the smart appliance.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
