Description

Technical Field

[0001] The present invention belongs to the technical field of home appliance noise reduction, and particularly relates to a washing machine capable of intelligently processing the influence of noise and a control method thereof. Background Art

[0002] In modern life, washing machines are basically present in the lives of every family. Under the current technology, washing machines will inevitably generate more or less noise during the water filling, washing, and drying processes. It is relatively difficult to avoid the generation of noise, so the influence of noise can be reduced from another perspective: operating the washing machine normally when there is already a relatively loud sound in the environment. Due to the characteristics of sound waves, when two sounds are emitted simultaneously, the decibel level of the combined sound does not increase linearly. For example, when two 60-decibel sounds (due to the complexity of sound and the large difference in the frequency spectra of different sound sources) are superimposed, it is approximately 66 decibels. Based on this principle, the corresponding audio can be emitted through a speaker or the surrounding environmental sound can be utilized, which is more suitable for processing and reducing the noise influence during the operation of the washing machine.

[0003] In order to reduce the influence of noise on the user's life and reduce the duration and distribution time of the noise, the invention is equipped with a noise sensor module to monitor the sound situation of the environment where the washing machine is located. After judging by the decibel level and duration of the sound, when both of these two parameters, namely the decibel level and the duration, exceed a certain value, the washing machine is intelligently controlled to start running. Without additional requirements for the motor and sound-absorbing materials, the user experience is improved. The washing machine is additionally equipped with a speaker, which can play built-in songs within a preset time to reduce the noise influence during the operation of the washing machine by using beautiful music. In this way, the influence of noise on the user's family members and neighbors is mitigated. Summary of the Invention

[0004] The purpose of the present invention is to provide a washing machine capable of intelligently processing the influence of noise and a control method thereof. By monitoring the sound situation of the environment where the washing machine is located through a noise sensor module, and judging by the decibel level and duration of the sound, when both of these two parameters, namely the decibel level and the duration, exceed a certain value, the washing machine is intelligently controlled to start running, thus solving the problems that the noise of the existing washing machine has a great influence on users and the noise duration is long.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention relates to a washing machine capable of intelligently processing the influence of noise, which includes a laundry module, a noise sensor, a speaker, a control board, a WiFi module, and a display board; the laundry module, the noise sensor, the speaker, the WiFi module, and the display board are all electrically connected to the control board; the laundry module is used to complete the washing function tasks; the noise sensor is used to sense the sound intensity and duration of the surrounding environment of the washing machine; the speaker is used to play specific audio that can reduce noise; the control board is used to perform intelligent analysis and judge whether to start running according to the uploaded data; the control board is communicatively connected to the APP of a mobile phone or an electronic device through the WiFi module; the APP is used to view the working status of the washing machine or send operation instructions to the control board.

[0007] As a preferred technical solution, the APP is also used for the user to perform network connection with the washing machine through WiFi when the washing machine is powered on for the first time.

[0008] As a preferred technical solution, the user can use the APP of the mobile phone or the electronic device to remotely control the washing machine to start or pause the washing work, select the washing mode, select the washing noise reduction audio, and the maximum noise value of the surrounding environment when the washing machine starts.

[0009] The present invention relates to a control method for a washing machine capable of intelligently processing the influence of noise, which includes the following steps:

[0010] Step S1: When the washing machine is powered on for the first time, the user performs network connection with the WiFi, the WiFi starts to work, and the user places the laundry and detergent in the washing machine in advance.

[0011] Step S2: In the standby state, the noise sensor continuously collects the surrounding environment sound information.

[0012] Step S3: The user communicates with the WiFi module of the washing machine through the mobile phone APP to make an appointment to set the next running time, running mode of the washing machine, and the noise mitigation audio that the speaker will play.

[0013] Step S4: The user communicates with the WiFi module of the washing machine through the mobile phone APP to remotely control the washing machine to start or pause the washing work, select the washing mode, and select the noise reduction audio.

[0014] Step S5: When communicating with the APP through WiFi connection, the intelligent noise processing mode is enabled.

[0015] Step S6: In the intelligent noise processing mode, the sound collected by the noise sensor is processed by the MCU to judge whether to perform washing.

[0016] Step S7: If the washing machine has normally completed the washing, rinsing, and drying functions, the washing machine automatically shuts down each component and sends the message "Washing completed" to the APP via WiFi.

[0017] As a preferred technical solution, in step S5, when the ambient sound collected by the noise sensor is judged by the MCU to exceed 50 decibels and the duration exceeds 5 minutes, the washing machine automatically starts the laundry module, normally starts the washing function, and sends the message "Start washing" to the APP when starting the washing.

[0018] As a preferred technical solution, in step S6, if the sound collected by the noise sensor is processed by the MCU and after waveform comparison, it is close to the sound waveform of the washing machine running in a quiet environment, it means that the external sound has temporarily weakened; if the external sound weakening lasts for 5 minutes, the washing machine automatically pauses the washing function of the laundry module and sends the message "Pause washing" to the APP when pausing the washing.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention jointly determines whether it is in a workable environment through the noise sensor module and the built-in control module, and the speaker, motor, and APP complete the interaction, reducing the impact of noise on people while ensuring the normal washing and rinsing of clothes, and improving the user experience.

[0021] (2) The present invention is additionally equipped with a speaker in the washing machine, which can play built-in songs within a preset time, using beautiful music to reduce the impact of noise during the operation of the washing machine. In this way, the impact of noise on the user's family and neighbors is mitigated.

[0022] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. Brief Description of the Drawings

[0028] The APP is also used for the user to perform network configuration connection with the washing machine through WiFi when the washing machine is powered on for the first time; the user can remotely control the washing machine to start or pause the washing work, select the washing mode, select the washing noise reduction audio, and the maximum noise value of the surrounding environment when the washing machine starts through the APP of the mobile phone or an electronic device.

[0029] The washing machine detects the sound of the environment where the washing machine is located through a built-in noise sensor; through MCU calculation, it can be determined whether it is a situation where noise does not need to be avoided, so as to avoid affecting the user. For example, the sound of cars on the road, the sound of decoration, the sound of TV, the sound of radio, etc. In this case, the environment is not quiet itself, and the washing machine can work normally during this period.

[0030] Please refer to Figure 2 As shown, the present invention is a control method for a washing machine that can intelligently process the influence of noise, including the following steps:

[0031] Step S1: When the washing machine is powered on for the first time, please ask the user to perform network configuration connection for WiFi, the WiFi starts to work, and the user places the laundry and detergent in the washing machine in advance;

[0032] Step S2: In the standby state, the noise sensor continuously collects the surrounding environment sound information;

[0033] Step S3: The user communicates with the washing machine WiFi module through the mobile phone APP to make an appointment to set the next operating time of the washing machine, the operating mode, and the noise reduction audio that the speaker will play accordingly.

[0034] Step S4: The user communicates with the washing machine WiFi module through the mobile phone APP to control the start or pause of the washing work of the washing machine in real time, select the washing mode, and select the noise reduction audio.

[0035] Step S5: When communicating with the APP through WiFi connection, the intelligent noise processing mode is enabled. When the environmental sound collected by the noise sensor is judged by the MCU to exceed 50 decibels and the duration exceeds 5 minutes, the washing machine automatically starts the washing module and normally starts the washing function. When starting the washing, it sends an information of "starting washing" to the APP.

[0036] Step S6: In the intelligent noise processing mode, the sound collected by the noise sensor is processed by the MCU to judge whether to wash. If the sound collected by the noise sensor is processed by the MCU and after waveform comparison, it is close to the sound waveform of the washing machine running in a quiet environment, it means that the external sound has temporarily weakened. If the external sound weakens for 5 minutes, the washing machine automatically pauses the washing function of the washing module and sends an information of "pausing washing" to the APP when pausing the washing.

[0037] Step S7: When the washing machine normally completes the washing, rinsing, and drying functions, the washing machine automatically shuts down each component and sends an information of "washing has been completed" to the APP through WiFi.
