Description

Technical Field

[0001] This disclosure relates to the field of intelligent electrical appliance technology, and in particular to an intelligent electrical appliance and its control method. Background Technology

[0002] As people's quality of life improves and technologies such as the internet, big data, artificial intelligence, and voice interaction become more widespread, traditional lifestyles are gradually changing, and the use of electrical appliances is increasingly moving towards intelligentization. While bringing greater convenience to users, the functions of various electrical appliances are also becoming more diversified.

[0003] Currently, smart home appliances equipped with voice interaction functions are becoming increasingly common, but in the field of smart constant temperature / instant hot water faucets, there are still many obstacles to the implementation of voice functions: First, acoustic interference is complex and difficult to filter out. The noise during the heating process exhibits wide-band characteristics, mainly including: (1) mechanical noise generated by water flow impact and valve core switching; (2) electromagnetic vibration noise and current humming when the heating tube or thick film heating body is working; (3) turbulent boiling sound, water hammer sound and structural vibration noise caused by thermal expansion and contraction generated by the instantaneous heating of cold water. The energy of the above heating noise is mainly concentrated in the 100Hz~2kHz frequency band, which happens to cover the core frequency range of human speech (especially vowels and voiced sounds). If conventional digital filters are used to hard cut off or deeply attenuate this frequency band, it will cause the effective human voice signal to be damaged synchronously, resulting in a sharp drop in the speech recognition rate; if no filtering is performed, the noise will directly cause voice wake-up failure, false triggering or command recognition error. Second, there is the problem of hardware reliability under harsh working conditions. The internal environment of smart appliances is often characterized by high temperature, high humidity, and even condensation, which can severely damage the lifespan and reliability of the voice module's circuit board and control board. Existing general-purpose voice module packaging solutions cannot simultaneously achieve waterproofing and thermal insulation while suppressing noise interference. Summary of the Invention

[0044] In this embodiment of the disclosure, the collection, storage, use, processing, transmission, provision, and disclosure of user personal information comply with relevant laws and regulations and do not violate public order and good morals.

[0045] Example 1

[0046] Figure 1This is a schematic diagram of the structure of a smart appliance provided in Embodiment 1 of this disclosure. The smart appliance involved in this embodiment is typically a faucet, such as... Figure 1 As shown, taking a smart appliance as an example, the smart appliance includes a smart appliance body 1, dual microphones 2, water outlet component 3, heating component 4, first protective structure 5, second protective structure 6, and third protective structure 7.

[0047] Dual microphones 2 are located on the side wall of the main body 1 of the smart appliance and above the first protective structure 5; the first protective structure 5 is located between the water outlet component 3 and the dual microphones 2; the second protective structure 6 is located between the heating component 4 and the first protective structure 5; the third protective structure 7 is wrapped around the lower outer side of the heating component 4.

[0048] Dual microphones 2 are used to collect audio signals;

[0049] In this embodiment, the dual microphones can also be understood as composite microphones, located away from the water outlet and within the protection range of the first protective structure. The dual microphones are typically positioned close to the water outlet, and their pickup direction is towards the user.

[0050] Furthermore, the reason for placing the dual microphones far from the water outlet is that the water outlet and the water pipe are bent. When the water flows through the bend, it will generate a lot of water flow noise, especially since heated water contains a lot of hot air bubbles, which are confined in the water pipe and generate bursting noise.

[0051] The first protective structure 5 is used to isolate the noise generated by the water outlet assembly 3 and / or the heating assembly 4, and to act as a baffle for the dual microphones 2 to prevent them from falling.

[0052] In one optional embodiment, the first protective structure is L-shaped. Specifically, the first protective structure includes a lateral extension portion and a vertical extension portion. The lateral extension portion covers the top of the water outlet pipe, and the vertical extension portion is attached to the side wall of the main body of the smart appliance (e.g., a faucet).

[0053] In this embodiment, an L-shaped first protective structure is used to isolate the noise generated by the water outlet pipe and the water outlet, as well as to isolate the high heat effect of hot water on the dual microphones and the control board. At the same time, the L-shaped first protective structure can also act as a baffle for the dual microphones to prevent them from falling into the smart appliance (e.g., faucet), and also to prevent noise from being directly coupled into the pickup holes of the dual microphones.

[0054] The second protective structure 6 is used to isolate the noise, heat and moisture generated by the heating component 4;

[0055] In this embodiment, the second protective structure is a vertically extending barrier structure, which can also be understood as the second protective structure being located between the heating component and the control board.

[0056] During the operation of smart appliances, the high temperature and humidity from the heating components naturally rise. The second protective structure, acting as a vertical physical barrier, cuts off the straight path between the heating zone and the control zone. This physically prevents the high heat and humidity from corroding the electronic components on the control board, while also absorbing residual noise overflowing from below, ensuring a relatively stable microenvironment in the top area where the control board is located.

[0057] The third protective structure 7 is used to confine the noise of the heating component 4 inside the main body of the smart appliance.

[0058] In this embodiment, the third protective structure is a shell structure that surrounds the heating component to prevent noise from escaping downwards. Specifically, the third protective structure is used to completely confine the noise generated by the heating component inside the smart appliance (e.g., a faucet) to prevent overflowing noise from affecting the main microphone that receives human voices.

[0059] Specifically, when the heating element is in operation, it generates highly penetrating low-frequency noise. The third protective structure (enclosing the lower part of the heating element) limits the noise from escaping at its source. Through physical density and enclosed space, the third protective structure confines most of the noise generated by the heating element within the internal cavity of the smart appliance (e.g., a faucet), preventing it from propagating upwards and interfering with the dual microphones above.

[0060] In an optional implementation, the dual microphones include a main microphone and an auxiliary microphone, and the audio signal includes a first audio signal acquired by the main microphone that contains the user's voice and internal noise of the smart appliance, and a second audio signal acquired by the auxiliary microphone that contains only the internal noise of the smart appliance.

[0061] In this embodiment, the dual-microphone system includes two microphones, which improves the voice recognition rate in the heated state compared to a traditional single-microphone system. One microphone is a main microphone for receiving human voice, and the other is an auxiliary microphone for receiving noise. The main microphone picks up the user's voice from outside the smart appliance (e.g., a faucet) while simultaneously mixing in internal noise from inside the smart appliance (e.g., the faucet). The auxiliary microphone picks up only internal noise from inside the smart appliance (e.g., the faucet) and does not pick up external user voice.

[0062] Specifically, the main microphone and the auxiliary microphone are integrated into one unit. The main microphone picks up sound towards the user side, while the auxiliary microphone picks up sound towards the heating element and the water outlet element.

[0063] In an alternative implementation, such as Figure 1 As shown, the smart appliance also includes a control board 8 and a water inlet pipe 9 for the smart appliance (e.g., a faucet). The control board 8 is located on the top of the main body 1 of the smart appliance.

[0064] Control board 8 is configured as follows:

[0065] Acquire a first audio signal from the main microphone that includes user voice and internal noise of the smart appliance, and a second audio signal from the auxiliary microphone that includes only internal noise of the smart appliance.

[0066] A reference noise signal is constructed based on the second audio signal;

[0067] The first audio signal is canceled based on the reference noise signal to filter out internal noise from the smart appliance and extract interference-free user voice.

[0068] In this embodiment, the control board integrates a noise processing unit, a voice processing unit, a speech unit, and an audio filter to run an adaptive cancellation algorithm to separate heating noise, water flow noise, and valve core noise (i.e., mechanical noise) from the first audio signal. Specifically, the noise processing unit is configured to generate an inverse cancellation signal based on a second audio signal collected by an auxiliary microphone, which contains only internal noise of the smart appliance. The audio filter is configured to superimpose the inverse cancellation signal onto the first audio signal to separate heating noise, water flow noise, and valve core noise.

[0069] It should be noted that since most of the noise is physically blocked by the first, second, and third protective structures, the noise floor received by the dual microphones is reduced. Therefore, the adaptive cancellation algorithm only needs to call the conventional "heated noise feature library" to complete the noise reduction without performing extremely high-intensity complex calculations.

[0070] In an alternative implementation, such as Figure 1 As shown, the water outlet assembly 3 includes a water outlet pipe 31 and a water outlet nozzle 32, with the water outlet pipe 31 connected to the water outlet nozzle 32; the water outlet pipe 31 and the water outlet nozzle 32 are arranged in a bent shape.

[0071] In the specific implementation process, for example, taking a smart appliance as a faucet, such as... Figure 1As shown, the bottom of the faucet is the water inlet pipe. Water enters the faucet's internal heating element through this pipe. Once activated, the heating element heats the cold water into hot water, which is then delivered to the spout through the outlet pipe, providing hot water. The dual microphone system consists of two microphones: a main microphone for receiving human voice and an auxiliary microphone for receiving noise. The main microphone picks up the user's voice outside the faucet, while also mixing in internal noise. The auxiliary microphone only picks up internal noise and does not capture external user voice. The dual microphones are positioned far from the spout because the spout and water pipe are bent; water flowing through the bend will generate more noise. The noise from large water flows, especially from heated water containing numerous hot air bubbles, creates bursting noise due to their confinement within the water pipes. This disclosure uses an L-shaped first protective structure to isolate noise from the water outlet pipe and spout, as well as to isolate the high-temperature effects of hot water on the dual microphones and control board. Simultaneously, the L-shaped first protective structure also acts as a baffle for the dual microphones, preventing them from falling into the faucet. Furthermore, since heating noise is greater than water flow noise and has stronger penetrating power, this disclosure includes a second protective structure to further isolate the noise, high heat (i.e., heat), and high humidity (i.e., moisture) from the heating component from the dual microphones and control board. Additionally, a third protective structure completely confines the noise generated by the heating component inside the faucet, preventing overflow noise from affecting the main microphone receiving human voices. Furthermore, an adaptive cancellation algorithm, implemented on the control board located on top of the faucet, separates heating noise, water flow noise, and valve core noise from the first audio signal.

[0072] Example 2

[0073] Figure 2 This is a flowchart illustrating a control method for a smart appliance provided in Embodiment 2 of this disclosure. This control method is applicable to the aforementioned smart appliance, such as... Figure 2 As shown, the control method includes:

[0074] S1. Receive the first audio signal collected by the main microphone, which includes the user's voice and the internal noise of the smart appliance, and the second audio signal collected by the auxiliary microphone, which only includes the internal noise of the smart appliance; the internal noise of the smart appliance includes heating noise, water flow and mechanical noise;

[0075] S2. In response to determining that the heating component is in working condition, extract heating noise, water flow and mechanical noise from the second audio signal;

[0076] S3. The first audio signal is canceled based on heating noise, water flow and mechanical noise to obtain interference-free user voice.

[0077] In this embodiment, when the heating component is working, the control board runs an adaptive cancellation algorithm to separate heating noise, water flow noise, and valve core noise (i.e., mechanical noise) from the first audio signal, thereby obtaining a pure human voice signal (i.e., interference-free user voice).

[0078] In an optional implementation, the control method further includes:

[0079] In response to the determination that the heating component is in a non-working state, water flow and mechanical noise are extracted from the second audio signal;

[0080] The first audio signal is canceled out based on water flow and mechanical noise to obtain interference-free user voice.

[0081] In this embodiment, when the heating component is not working, the control board runs an adaptive cancellation algorithm to separate water flow noise and valve core noise (i.e. mechanical noise) from the first audio signal, thereby obtaining a pure human voice signal (i.e., interference-free user voice).

[0082] In an optional implementation, S3 includes:

[0083] Generate a cancellation signal that is out of phase with the heating noise, water flow, and mechanical noise;

[0084] The cancellation signal is superimposed on the first audio signal to filter out heating noise, water flow and mechanical noise from the first audio signal, so as to obtain interference-free user voice.

[0085] In an optional implementation, the control method further includes:

[0086] User voice commands are used to perform corresponding control operations on smart appliances without interference, and status feedback is provided on the control results.

[0087] In this embodiment, semantic parsing is performed on the user's voice without interference to determine the user's intention (such as adjusting the temperature, changing the water volume, etc.); based on the parsing results, the heating components and solenoid valve inside the faucet are driven to perform corresponding actions; after the execution is completed, the current working status (such as the actual water temperature and valve opening) is fed back for confirmation, forming a closed-loop control.

[0088] Furthermore, after the task is completed, the smart appliance (such as a faucet) enters a low-power standby state, continuously listening for trigger commands. Once a valid audio signal is received again, the process will jump back to the "dual-microphone acquisition" step, achieving all-weather intelligent response.

[0089] This implementation method uses dual microphones to collect audio signals and runs an adaptive cancellation algorithm to suppress water flow noise, mechanical noise, electromagnetic humming of the heating component, and heating turbulence noise. Through waterproofing and heat insulation, it ensures that the dual microphones and control board can work in a stable environment, significantly improving the voice recognition accuracy of smart thermostatic or instant hot water faucets in the heating state. It achieves simultaneous suppression of multiple types of noise and adopts relevant control methods to make the whole process more intelligent and convenient.
