[0052] Therefore, it is possible to analyze the source of noise while detecting it, improving the convenience and timeliness of use;

[0053] When the clutch is started, in order to avoid unnecessary influence of the noise detection clamping arm 2 on the vibration detection box 6, a detection box placement compartment 108 is formed between the upper baffle plate 101, the vibration detection groove 102 and the side baffle plate 103, and the vibration detection box 6 is arranged inside the detection box placement compartment 108. During use, the vibration detection box 6 is suspended inside the detection box placement compartment 108 but is in close contact with the clutch, a vibration detection groove 102 is opened on the noise detection clamping arm 2, and the vibration detection box 6 is arranged inside the vibration detection groove 102, and an upper baffle plate 101 is fixedly arranged on the vibration detection groove 102 just above the vibration detection box 6, and a side baffle plate 103 is arranged on the side of the vibration detection box 6 away from the noise detection clamping arm 2, and the side baffle plate 103 is fixedly arranged on the vibration detection clamping arm 1, and the side baffle plate 103 03 is fixedly provided with a plurality of electromagnet assemblies 5, wherein when the electromagnet assemblies 5 are not started, the electromagnet assemblies 5 are used to fix the vibration detection box 6, and when the vibration detection box 6 is in use, the electromagnet assemblies 5 are started, and the magnetic poles generated by the electromagnet assemblies 5 are opposite to the magnetic poles of the vibration detection box 6, so that the vibration detection box 6 can be pushed to one side of the clutch, and a rubber damping pad 604 is fixedly provided on one side of the vibration detection box 6, and the rubber damping pad 604 is against the clutch, and the friction between the rubber damping pad 604 and the clutch is increased by the rubber damping pad 604 on the vibration detection box 6, and the clutch is detected.

[0055] A fifth magnet 603 is fixedly provided on one side of the vibration detection box 6 close to the side baffle 103, and the fifth magnet 603 corresponds to the electromagnet assembly 5.

When in use, the iron core 501 on the electromagnet assembly 5 generates the same magnetism as the fifth magnet 603, and repel each other. When not in use, the magnetism on the iron core 501 disappears, and the fifth magnet 603 is adsorbed on the electromagnet assembly 5, thereby achieving the purpose of fixing the vibration detection box 6.

[0057] Both ends of the vertical magnet 706 are fixed inside the vertical detection shell 703 by vertical springs 710. Similarly, the vertical magnet 706 is fixed inside the vertical detection shell 703 by vertical springs 710. Therefore, the vertical magnet 706 can slide inside the vertical detection shell 703 to perform vertical detection. When the vibration detection box 6 slides vertically, the vertical magnet 706 is vertically slid inside the vertical detection shell 703. When the vibration detection box 6 slides horizontally, the horizontal magnet 704 is horizontally slid inside the horizontal detection shell 702.

[0060] Furthermore, in order to improve the stability between the vibration detection clamping arm 1 and the noise detection clamping arm 2 and the clutch, as shown in FIG. Figure 1 and Figure 3 As shown, the inner side surface of the vibration detection clamping arm 1 is provided with an airbag through groove 104, and the inner side surface of the noise detection clamping arm 2 is provided with an airbag through groove 204. Airbags 4 are arranged inside the airbag through groove 104 and the airbag through groove 204.

[0063] like Figure 1-Figure 11 As shown, the principle of the washing machine clutch noise detection mechanism provided in this embodiment is as follows:

[0064] A vibration detection mechanism 7 is fixedly arranged inside the vibration detection box 6. The vibration detection mechanism 7 is a cross-shaped structure. The horizontal vibration frequency can be detected through the horizontal detection housing 702, and the vertical vibration frequency can be detected through the vertical detection housing 703. At the same time, two are arranged in the horizontal direction and the vertical direction, and the average value is obtained during the detection process to improve the detection accuracy;

[0065] During the detection process, due to the vibration of the clutch, the horizontal magnet 704 will slide inside the horizontal detection housing 702, and the vertical magnet 706 will slide inside the vertical detection housing 703. When the horizontal magnet 704 slides, the horizontal coil 705 cuts the magnetic flux line, and when the vertical magnet 706 slides, the vertical coil 707 cuts the magnetic flux line, and the generated induced current is transmitted to the processor;

[0066] Therefore, it is possible to analyze the source of noise while detecting it, improving the convenience and timeliness of use;

[0067] The magnetic poles generated by the electromagnet assembly 5 are opposite to the magnetic poles of the vibration detection box 6, so the vibration detection box 6 can be pushed to one side of the clutch. A rubber damping pad 604 is fixedly provided on one side of the vibration detection box 6, and the rubber damping pad 604 is against the clutch. The rubber damping pad 604 on the vibration detection box 6 increases the friction with the clutch and detects the clutch. In order to prevent the vibration detection box 6 from falling off when not in use, the electromagnet assembly 5 is closed and adsorbed to the side baffle 103 under the action of magnetic force, thereby improving the stability and service life of the vibration detection box 6.

[0068] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0069] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
