[0038] This utility model embodiment provides a garment care device 1 with a door body 20, combined with... Figures 1-4 As shown, it includes:
[0039] Inner door cover 21;
[0040] Sound acquisition module 30, which is installed with the inner door cover 21;
[0041] When the door 20 is closed, the inner cover 21 extends into the inner drum 10 of the garment care device 1. The sound acquisition module 30 is configured to sense the sound waves during the rotation of the inner drum 10 in order to identify the operating status of the inner drum 10.
[0042] Specifically, the door body 20 includes a door trim panel 24, and the inner door cover 21 is fixed to the door trim panel 24 and located on the back side of the door body 20. The door trim panel 24 is rotatably mounted on the housing 50 of the garment care device 1 via a hinge assembly, and the door trim panel 24 drives the inner door cover 21 to open and close at the opening 101 of the inner cylinder 10. When the door body 20 is closed, the inner door cover 21 can extend into the inner cylinder 10. The door trim panel 24 not only forms a protective structure for the sound acquisition module 30 to protect it from dust, moisture, and other environmental factors, but also forms the outer surface of the garment care device 1, contributing to the overall aesthetics. In some embodiments, the wires used to connect the sound acquisition module 30 can pass through the hinge assembly to the door trim panel 24, and then enter the inner door cover 21 to connect with the sound acquisition module 30.
[0043] Clothing care devices 1, such as washing machines or washer-dryers, generate vibrations or impacts during operation due to factors such as friction, impact, balance, or foreign objects inside the drum. These sounds often contain a lot of information about the device's operating status. In this embodiment, a sound acquisition module 30 is set up to sense the sound waves generated during the rotation of the inner drum 10. For example, it can identify unexpected objects in the washing load, diagnose mechanical faults, or detect other operating conditions. This detection method is simple and convenient, reduces structural complexity, effectively reduces usage costs, and effectively ensures the accuracy of detection, thereby improving the user experience.
[0044] In addition, by placing the sound acquisition module 30 inside the door cover 21, it can prevent the sound acquisition module 30 from directly contacting the washing water and causing malfunctions, thus ensuring the stable operation of the sound acquisition module 30. On the other hand, the door cover 21 can form a sound-focusing structure for the sound acquisition module 30, so that the obtained sound information is more accurate and reliable.
[0045] Example 1
[0046] The sound waves include the noise generated by foreign objects striking the inner cylinder 10 during its rotation.
[0047] During daily use, users sometimes forget to remove items from their clothing pockets, such as metal keys, electronic keys, and wireless earphones. These items are easily damaged as they roll with the clothes. In particular, electronic devices are prone to water ingress, and hard objects can not only scratch clothes but also damage the washing machine. If they fall between the inner drum 10 and the outer drum, they are difficult to remove.
[0048] Therefore, this embodiment uses a sound acquisition module 30 to sense the noise generated by foreign objects striking the inner cylinder 10 during rotation, thereby realizing the detection of foreign objects inside the cylinder. Compared with the existing methods of using cameras or infrared detectors to detect foreign objects inside the cylinder, the detection structure in this embodiment effectively reduces the cost of use, and the detection method is simple, convenient, and highly accurate, thus improving the user experience.
[0049] Optionally, in this embodiment, when the inner drum 10 rotates to execute the washing program, the sound acquisition module 30 reads the sound information of the washing process, filters out the normal washing collision sounds such as washing, rinsing, spin-drying, zippers, and buttons through the local database, and defines other sounds as foreign object sounds; when the sound acquisition module 30 acquires foreign object sounds, it controls to pause the washing process and sends a reminder message to notify the user to remove the foreign object in time to avoid property damage or further damage.
[0050] Example 2
[0051] The sound waves include the rotation noise of the inner cylinder 10.
[0052] By analyzing the collected sound information, users can quickly locate the cause of the abnormality and ensure the normal operation of the inner cylinder 10. Specifically, the rotation noise of the inner cylinder 10 includes the sound of the cylinder shaking caused by abnormal rotation of the inner cylinder 10.
[0053] In some preferred embodiments, such as Figure 2 As shown, it also includes: a sound wave generating device 40, which is configured to generate an anti-phase sound wave based on the sound wave to cancel out the rotation noise of the inner drum 10. Specifically, the sound wave generating device 40 may be activated after the cause of the abnormality is located through sound information; the sound wave generating device 40 may also be used to cancel out the vibration noise that is unavoidably generated during tumbling and spin-drying in the washing process, thereby improving the user experience.
[0054] In some embodiments, the sound wave generator 40 is installed with the inner door cover 21. Furthermore, the sound wave generator 40 is positioned close to the sound acquisition module 30, enabling the sound wave generator 40 to respond quickly and emit sound waves with a phase opposite to the noise, achieving effective noise cancellation; it also makes more efficient use of the space within the inner door cover 21, simplifies the system structure, and reduces the complexity of signal transmission.
[0055] Example 3
[0056] like Figure 1 As shown, the inner door cover 21 extends toward the inner cylinder 10 to form a chamber 22, and the sound acquisition module 30 is located inside the chamber 22. On the one hand, the chamber 22 can protect the sound acquisition module 30 and the sound wave generating device 40 from dust, moisture and other environmental factors; on the other hand, the chamber 22 can form a sound-focusing structure for the sound acquisition module 30 and a sound-amplifying structure for the sound wave generating device 40. In some embodiments, the inner door cover 21 is a door glass.
[0057] Furthermore, the outline of the inner door cover 21 gradually decreases along the axial direction of the inner cylinder 10 from the outside to the inside of the cylinder; in some preferred embodiments, the inner door cover 21 has a bowl-shaped structure; in other preferred embodiments, the inner door cover 21 has a conical structure; this structure can further improve the sound focusing effect of the sound acquisition module 30 and the sound amplification effect of the sound wave generating device 40.
[0058] In some preferred embodiments, the sound acquisition module 30 is located at the end of the inner door cover 21 near the inner cylinder 10. Specifically, a vertical plane 23 is formed at the front end of the inner door cover 21, and the sound acquisition module 30 and the sound wave generating device 40 are installed on the vertical plane 23. In this case, the inner door cover 21 has a bowl-shaped or conical structure surrounding the sound acquisition module 30 and the sound wave generating device 40, which further improves the sound focusing effect of the sound acquisition module 30, optimizes the clarity of sound reception, and improves the accuracy of the detection structure; it also further improves the sound amplification effect of the sound wave generating device 40, which is conducive to maintaining the best noise reduction effect.
[0059] Furthermore, the sound acquisition module 30 is attached to the inner surface of the inner door cover 21. Specifically, the knocking sound of foreign objects inside the cylinder or the vibration sound generated by the rotation of the inner cylinder 10 can be transmitted through a solid medium. Therefore, attaching the sound acquisition module 30 to the inner surface of the inner door cover 21 can also expand the sound reception range, improve the directness and clarity of the acquired sound, and thus improve the accuracy of the detection results.
[0060] The sound acquisition module 30 is installed on the inner door cover 21 by means of a snap or thread, which simplifies the installation method and facilitates later maintenance and upgrades.
[0061] In some preferred embodiments, it further includes: a reminder module connected to the sound acquisition module 30, which issues a reminder message when the sound acquisition module 30 senses a foreign object inside the cylinder.
[0062] Furthermore, the reminder module includes one or more of an audio-visual reminder module, a voice reminder module, and a wireless communication reminder module, used to issue reminder information including audio-visual reminder messages, voice reminder messages, and messages sent to the client.
[0063] In some preferred embodiments, the sound acquisition module 30 includes a microphone or a microphone array; wherein, the microphone array can provide better acquisition effect and reliability.
[0064] The sound acquisition module 30 may be provided; in some preferred embodiments, such as Figure 3 As shown, multiple sound acquisition modules 30 are deployed, and the detection coverage and accuracy can be expanded by adjusting the detection position of each sound acquisition module 30.
[0065] Example 4
[0066] This utility model embodiment provides a garment care device 1, combined with... Figures 1-4As shown, the device includes a door 20 of the garment care device 1 as described in the above embodiments. In some embodiments, the garment care device 1 can be used as a washing machine, and in other embodiments, it can be used as a washer-dryer combo.
[0067] Clothing care devices 1, such as washing machines or washer-dryers, generate vibrations or impacts during operation due to factors such as friction, impact, balance, or foreign objects inside the drum. These sounds often contain a lot of information about the device's operating status. In this embodiment, a sound acquisition module 30 is set up to sense the sound waves generated during the rotation of the inner drum 10. For example, it can identify unexpected objects in the washing load, diagnose mechanical faults, or detect other operating conditions. This detection method is simple and convenient, reduces structural complexity, effectively reduces usage costs, and effectively ensures the accuracy of detection, thereby improving the user experience.
[0068] By placing the sound acquisition module 30 inside the door cover 21, it can prevent the sound acquisition module 30 from directly contacting the washing water and causing malfunctions, thus ensuring the stable operation of the sound acquisition module 30. On the other hand, the door cover 21 can form a sound-focusing structure for the sound acquisition module 30, so that the obtained sound information is more accurate and reliable.
[0069] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
