Embodiments
[0037] The utility model embodiment provides a kind of clothes care device 1, combined Figures 1-5 As shown, comprising:
[0038] Shell 10;
[0039] Cylinder 20, the cylinder 20 is arranged in the shell 10, and the cylinder 20 includes a clothes feeding port 21;
[0040] And the door body 30 installed with the shell 10, the door body 30 opens and closes in the clothes feeding port 21;
[0041] Noise reduction assembly is configured as the device for generating reverse phase sound wave according to the noise of clothes care device 1 when running;Wherein, at least two described noise reduction assemblies are configured on clothes care device 1, to constitute multiple noise reduction of clothes care device 1.
[0042] Specifically, human hearing range is 16Hz-20000Hz, and the noise frequency of washing machine is usually between 50Hz to 1000Hz; Washing machine motor and mechanical parts produce vibration and noise when running, and the frequency of these noises is mainly concentrated in low frequency band, generally between 50Hz to 1000Hz; Therefore, the embodiment utilizes active noise cancellation technology, and at least two noise reduction assemblies are configured to generate phase-reversed audio waves and mutually offset the vibration noise waves of clothes care device, to form multiple noise reduction structure of clothes care device 1;The noise of different regions of clothes care device 1 is more accurately processed, effectively reduces the noise of clothes care device 1 when running and dewatering, improves the use experience of user;And the use of sound insulation cotton, sound absorbing cotton and a large number of shock-absorbing components can be reduced, to reduce component cost and assembly process demand and cost.It should be understood that multiple noise reduction assemblies can be configured according to the noise source or noise reduction demand of clothes care device 1 to adapt to different noise reduction scenarios.
[0043] In some embodiments, at least one of the noise reduction assemblies is mounted on the door body 30, and at least one of the noise reduction assemblies is mounted on the bottom of the shell 10. In this embodiment, the first noise reduction assembly 41 is mounted on the door body 30, and the second noise reduction assembly 42 is mounted on the bottom of the shell 10. Specifically, the first noise reduction assembly 41 generates audio waves with opposite phases to cancel out the vibration noise waves between the door body 30 and the drum body 20, and the second noise reduction assembly 42 generates audio waves with opposite phases to cancel out the vibration noise waves at the bottom of the shell 20, thereby forming a multi-noise reduction structure of the clothes care device 1.
[0044] In some preferred embodiments, the first noise reduction assembly 41 and the second noise reduction assembly 42 are ANC (Active Noise Cancellation, active noise reduction) noise reduction assemblies. The ANC noise reduction assembly can be a feed-forward active noise reduction structure, a feedback active noise reduction structure, or a hybrid active noise reduction structure combining feed-forward and feedback.
[0045] In some preferred embodiments, the first noise reduction assembly 41 and the second noise reduction assembly 42 each include a processing module 401, a sound wave acquisition module 402, and a sound wave generation module 403. The processing module 401 analyzes the noise information obtained by the sound wave acquisition module 402 and controls the sound wave generation module 403 to generate sound wave signals with opposite phases to the noise information. That is, the first noise reduction assembly 41 and the second noise reduction assembly 42 can more effectively capture and process noise in the noise reduction area they are responsible for, thereby improving the overall noise reduction effect, and the parallel operation of the first noise reduction assembly 41 and the second noise reduction assembly 42 can ensure real-time noise reduction.
[0046] Further, each noise reduction assembly can independently perform noise reduction. In some preferred embodiments, the noise reduction assemblies can be configured to independently or in combination perform noise reduction according to different washing stages of the clothes care device. For example, during the water inlet soaking stage, the washing and stain removal stage, and the rinsing stage, the noise of the clothes care device is mainly caused by the washing water flow and the clothes in the inner drum tumbling and falling, so the first noise reduction assembly 41 can be configured to perform noise reduction. When the clothes care device 1 enters the dehydration stage, the high-speed rotation of the inner drum causes the clothes care device 1 to vibrate as a whole, at which time the first noise reduction assembly 41 and the second noise reduction assembly 42 can be configured to perform noise reduction simultaneously to optimize the noise reduction effect.
[0047] In some optional embodiments, the sound wave acquisition module 402 is a microphone. One microphone can be provided, or multiple microphones can be provided to enhance the noise capturing capability, which helps to more comprehensively understand the characteristics of the noise and thus more effectively cancel out the noise.
[0048] In some alternative embodiments, the sound wave generating module 403 is a loudspeaker; specifically, the loudspeaker, as the sound wave generating module 403, can not only efficiently convert electrical signals into sound wave signals, but also has a wide frequency response range, covering a wide frequency band from low frequency to high frequency, so as to quickly and accurately generate sound waves that are opposite in phase to noise, thereby canceling noise, and has good stability and reliability during long-term use.
[0049] In this embodiment, the working process of the ANC noise reduction component includes at least the following: using one or more microphones to capture noise information during the operation of the garment care device 1; using the processing module 401 to analyze and process the captured noise information to generate a sound wave signal with the opposite phase to the noise information; and emitting the generated anti-noise signal through a speaker to meet and cancel out the noise of the garment care device 1. The microphone can detect the noise level in the garment care device 1 in real time, provide timely feedback, and adjust and modify the sound wave generated by the speaker to more accurately process the noise of the garment care device 1.
[0050] In some embodiments, at least one noise reduction component is installed inside the door 30; in this embodiment, combined with Figure 1 , Figures 4-5 As shown, the first noise reduction component 41 is installed inside the door body 30. On the one hand, this optimizes space utilization; that is, the arrangement in this embodiment can fully utilize the internal space of the door body 30, which is beneficial to the overall compactness and aesthetics of the clothing care device 1. On the other hand, it effectively protects the first noise reduction component 41; that is, the internal environment of the door body 30 is relatively closed and stable, and the arrangement in this embodiment can prevent the first noise reduction component 41 from being affected by external interference and damage, thus helping to extend the service life of the first noise reduction component 41. It should be understood that multiple first noise reduction components 41 can also be arranged at different positions on the door body 30, thereby improving the accuracy of noise reduction processing and optimizing the noise reduction effect.
[0051] Furthermore, the first noise reduction component 41 is positioned close to the clothing inlet 21. Specifically, the clothing inlet 21 is one of the main areas where noise is generated, including friction noise between the door 30 and the clothing inlet 21, friction noise between the clothing and the cylinder wall, and water flow noise. Moreover, the noise may be amplified at the clothing inlet 21 due to resonance or reflection. Therefore, positioning the first noise reduction component 41 close to the clothing inlet 21 can accurately reduce these noises and improve the noise reduction effect.
[0052] In some preferred embodiments, the door body 30 is provided with a display module 31, and the first noise reduction assembly 41 is integrated in the display module 31. The design in this embodiment can save space, and no additional space is needed for the first noise reduction assembly 41. Integrating the first noise reduction assembly 41 in the display module 31 helps to simplify the overall circuit design, reduce the number of cables and connectors, and reduce production costs and maintenance difficulty.
[0053] Specifically, the door body 30 further comprises a window 32, and the display module 31 is located above the window 32. That is, the door body 30 is the main operation area and observation area of the user when using the laundry care device 1. The arrangement in this embodiment can significantly reduce the noise interference suffered by the user when operating the display module 31 or observing the washing state from the window 32, and improve the interaction comfort.
[0054] In some embodiments, at least one noise reduction assembly is arranged between the bottom of the shell 10 and the drum 20. In this embodiment, in combination with the first noise reduction assembly 41 arranged between the door body 30 and the drum 20, the noise reduction effect is further improved. Figures 1-3 As shown, the second noise reduction assembly 42 is arranged between the bottom of the shell 10 and the drum 20. During the operation of the laundry care device 1, various noises are generated, such as the noise generated by the motor, the noise generated when the inner drum rotates under the drive of the motor, and the noise generated when the clothes are not balanced in the inner drum. Therefore, the arrangement of the second noise reduction assembly 42 in this embodiment can effectively reduce the noise level, reduce the propagation and diffusion of noise, and fully utilize the original idle space in the shell 10, so that the overall structure of the laundry care device 1 is more compact. It should be understood that a plurality of second noise reduction assemblies 42 can also be arranged at different positions between the bottom of the shell 10 and the drum 20, so as to improve the accuracy of noise reduction processing and optimize the noise reduction effect.
[0055] Further, the bottom of the drum 20 is provided with a drainage structure. Specifically, the bottom of the drum 20 is provided with a drainage port 22, and the drainage port 22 is generally connected with a drainage pump 23. During the drainage stage at the end of washing, the drainage pump 23 often generates a lot of noise, thereby increasing the working noise of the laundry care device 1. In some embodiments, the second noise reduction assembly 42 is arranged close to the drainage structure to more directly suppress the noise generated during the drainage process.
[0056] In some preferred embodiments, the shell 10 comprises a base 11, and the second noise reduction assembly 42 is located in the base 11; during the spinning and dehydration process of the laundry care device 1, the drum 20 is in high-speed operation process, and the laundry care device 1 will inevitably vibrate, so that noise will be generated between the base 11 and the ground, therefore, the embodiment can further reduce the noise during the operation of the laundry care device 1; in addition, due to the detachable assembly mode of the base 11, the maintenance and replacement of the second noise reduction assembly 42 are more convenient.
[0057] Further, the base 11 is provided with a fixing support 12, and the second noise reduction assembly 42 is installed on the fixing support 12. Specifically, the fixing support 12 is fixedly installed on the base 11 by means of fasteners such as screws or bolts, and an installation platform 121 is formed on the fixing support 12, and the second noise reduction assembly 42 is fixed on the installation platform 121; wherein the second noise reduction assembly 42 can be fixed with the installation platform 121 by means of buckle or threaded connection. On the one hand, the embodiment can simplify the installation mode and facilitate the adjustment of the installation position or angle, and on the other hand, the fixing support 12 provides a stable installation platform 121, which can effectively ensure that the second noise reduction assembly 42 will not be loosened or displaced due to washing vibration or external force, and is helpful to maintain the noise reduction performance of the second noise reduction assembly 42 and play a stable noise reduction effect in long-term use.
[0058] In some preferred embodiments, the base 11 is also provided with a damping foot 13, which effectively absorbs and disperses the vibration and noise during the operation of the laundry care device 1, and cooperates with the second noise reduction assembly 42 to further improve the noise reduction effect.
[0059] Although the embodiments of the present application have been disclosed as above, it is not limited to the application listed in the specification and the embodiments, and it can be fully applied to various fields suitable for the present application. For those skilled in the art, other modifications can be easily realized, therefore, the present application is not limited to specific details and the figures shown and described herein, without departing from the general concept defined by the claims and the equivalent scope.
