[0058] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0059] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0060] Some electrical appliances are equipped with drawers and a driving mechanism for driving the drawers to open. The control device of the electrical appliance can receive a sound signal emitted by a user and control the driving mechanism based on the sound signal to drive the drawers to open.

[0061] In the related art, when an electrical device controls the opening of a drawer of the electrical device based on a sound signal, an accidental touch may occur, causing the drawer to be opened accidentally, which will seriously affect the user experience.

[0062] Combine Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides an electrical device 10, which includes a drawer 201 control system 100 and a device body 200. The drawer 201 control system 100 is disposed on the device body 200, and the device body 200 is provided with a drawer 201. The drawer 201 control system 100 includes a drawer control device 101, a sound collection module 102, a human body sensing module 103, and a driving mechanism 104. The driving mechanism 104 is in transmission connection with the drawer 201 and is capable of driving the drawer 201 to open and close. The sound collection module 102 is capable of collecting sounds in the environment where the electrical device 10 is located and converting the sounds into corresponding sound signals to be sent to the drawer control device 101. The human body sensing module 103 is capable of sensing whether there is a person within the effective triggering range of the electrical device 10 and, upon sensing that there is a person within the effective triggering range of the electrical device 10, generates a corresponding sensing signal to be sent to the drawer control device 101.

[0063] The drawer control device 101 is in communication with the sound collection module 102, the human body sensing module 103, and the drive mechanism 104. The drawer control device 101 can receive sound signals from the sound collection module 102 and sensing signals from the human body sensing module 103. When a drawer 201 of the electrical device 10 is closed, the drawer control device 101 analyzes the received sound and sensing signals and their parameters to determine whether to control the drive mechanism 104 to open the drawer 201.

[0064] In some embodiments, the sound collection module 102 includes a piezoelectric film sensor and a signal conditioning circuit. The piezoelectric film sensor uses the piezoelectric effect to detect and convert mechanical stress or pressure into a sound signal, and then inputs the sound signal into the signal conditioning circuit. The signal conditioning circuit processes the input to improve its quality, reduce noise, and increase the signal-to-noise ratio, and then inputs the conditioned sound signal into the drawer control device 101.

[0065] In some embodiments, the human body sensing module 103 may include a human body proximity sensor. The human body proximity sensor is based on the principle of Doppler technology and uses a microwave-specific microprocessor and a planar sensing antenna. When it senses a person within the effective trigger range of the electrical device, it generates a corresponding sensing signal and sends it to the drawer control device.

[0066] In conjunction with the electrical device provided by the embodiment of the present disclosure, the embodiment of the present disclosure provides a drawer control method for the electrical device, the control method is executed by the drawer control device, such as Figure 3 As shown, the control method includes the following steps:

[0067] S301: When the drawer of the electrical device is closed, the drawer control device determines that a specific type of sound exists in the environment of the electrical device, compares the sound intensity with the intensity threshold, and matches the voiceprint feature of the sound with the standard feature.

[0068] When the drawer of the electrical device is closed, the sound collection module can collect sounds in the environment where the electrical device is located and convert the sounds into corresponding sound signals to be sent to the drawer control device. The drawer control device can determine whether the sound collected by the sound collection module is a specific type of sound based on the sound signal. When the drawer control device determines that the sound collected by the sound collection module is a specific type of sound, it can be determined that the specific type of sound exists in the environment where the electrical device is located. In the embodiment of the present disclosure, the specific type of sound can be the sound of a user knocking on the drawer, the sound of a user including a voice command (such as "open the door"), the sound of a user coughing, etc.

[0069] In the disclosed embodiments, a sound intensity threshold and standard voiceprint features can be pre-set. The standard features are the voiceprint features of users with permission to use the electrical device. The intensity threshold can be determined based on actual design needs, and users can customize the intensity threshold to meet their needs. In the disclosed embodiments, the voiceprint features of users with permission to use the electrical device can be stored in a standard feature set.

[0070] After receiving the sound signal, the drawer control device can extract sound intensity and voiceprint features based on the sound signal. Here, the frequency and amplitude of the sound signal are related to the sound intensity, so the sound intensity can be determined based on the frequency, amplitude, and frequency of the sound signal. Furthermore, after receiving the sound signal, the drawer control device can use a voiceprint recognition algorithm to identify the sound signal and determine the voiceprint features corresponding to the sound.

[0071] After determining the sound intensity and voiceprint features of the sound, the sound intensity is compared with the intensity threshold to determine whether the sound intensity is greater than the intensity threshold; the voiceprint features of the sound are matched with the standard features to determine whether the voiceprint features of the sound belong to the standard features in the standard feature set.

[0072] S302: When determining that the sound intensity is greater than the intensity threshold and the voiceprint feature is a standard feature, the drawer control device detects whether there is a person within the effective triggering range of the electrical device.

[0073] Figure 4 An exemplary schematic diagram of an effective trigger range of an electrical device is shown, wherein: Figure 4 yes Figure 1 A bird's-eye view. Figure 4 In the figure, the circular area A represents the effective trigger range of the electrical device. In the embodiment of the present disclosure, the human body sensing module can sense whether there is a person within the effective trigger range of the electrical device, and generate a corresponding sensing signal to be sent to the drawer control device when sensing that there is a person within the effective trigger range of the electrical device.

[0074] If the drawer control device determines that the sound intensity is greater than the intensity threshold and the voiceprint characteristics meet the standard characteristics, it can detect whether the sensing signal sent by the human body sensor module is received. It is understood that if the sensing signal sent by the human body sensor module is received, it means that a person is detected within the effective triggering range of the electrical device; if the sensing signal sent by the human body sensor module is not received, it means that no person is detected within the effective triggering range of the electrical device.

[0075] S303: When the drawer control device detects that there is a person in the effective triggering range of the electrical device, it controls the drawer to open.

[0076] In the embodiment of the present disclosure, when the drawer control device detects that there is a person in the effective triggering range of the electrical device, it drives the drawer to open by controlling the driving mechanism.

[0077] S304: When the drawer control device detects no person in the effective triggering range of the electrical device, the drawer is controlled to remain closed.

[0078] In the embodiment of the present disclosure, when the drawer control device does not detect that there is anyone in the effective triggering range of the electrical device, the driving mechanism does not perform corresponding work to keep the drawer closed.

[0079] The drawer control method for electrical equipment provided by the embodiment of the present disclosure determines whether to trigger the control of opening the drawer based on three judgment conditions: the sound intensity and voiceprint characteristics of the sound, and whether there is a person within the effective trigger range of the electrical equipment. This trigger judgment method has a high accuracy rate and can reduce the probability of false touch when controlling the opening of the drawer of the electrical equipment based on sound signals.

[0080] In some embodiments, a user may first make a sound and then walk into the effective trigger range of an electrical device. In this case, the drawer control device may not immediately detect that there is a person within the effective trigger range of the electrical device after determining that the sound intensity exceeds the intensity threshold and the voiceprint characteristics meet the standard characteristics. This may cause a false judgment and prevent the drawer from opening.

[0081] In order to avoid the above situation, the embodiment of the present disclosure can pre-set a first preset time length, and the first preset time length can be determined according to actual design needs. For example, the first preset time length can be 5 seconds, 8 seconds or 10 seconds, etc. When it is detected that there is a person in the effective trigger range of the electrical device, the drawer is controlled to open, including: when it is detected that there is a person in the effective trigger range of the electrical device within the first preset time length, the drawer is controlled to open. When no person is detected in the effective trigger range of the electrical device, the drawer is controlled to remain closed, including: when it is detected that there is no person in the effective trigger range of the electrical device within the first preset time length, the drawer is controlled to remain closed.

[0082] That is, if it is determined that the sound intensity is greater than the intensity threshold and the voiceprint characteristics are standard characteristics, the drawer control device can continuously detect whether there is a person within the effective trigger range of the electrical device for a first preset period of time. This avoids the situation where the drawer cannot be opened due to misjudgment if the user first makes a sound and then walks into the effective trigger range of the electrical device.

[0083] In some embodiments, when a person is detected within the effective trigger range of the electrical device, the drawer is controlled to open, including: when a person is detected within the effective trigger range of the electrical device, detecting the positional relationship between the person and the limit range of the drawer, the limit range being the space occupied by the drawer when it is fully opened; when it is detected that the person is outside the limit range of the drawer, the drawer is controlled to open fully; when it is detected that the person is within the limit range of the drawer, a safety distance is determined based on the distance between the person and the drawer, and the drawer is controlled to extend the safety distance, the safety distance being less than the distance extended when the drawer is fully opened.

[0084] like Figure 5 As shown, the embodiment of the present disclosure provides another drawer control method for an electrical device, the control method is a drawer control device, and the control method includes the following steps:

[0085] S501: When the drawer of the electrical device is closed, the drawer control device determines that a specific type of sound exists in the environment of the electrical device, compares the sound intensity with the intensity threshold, and matches the voiceprint feature of the sound with the standard feature.

[0086] S502: When determining that the sound intensity is greater than the intensity threshold and the voiceprint feature is a standard feature, the drawer control device detects whether there is a person within the effective triggering range of the electrical device.

[0087] S503: When the drawer control device detects that there is a person in the effective triggering range of the electrical device, it detects the positional relationship between the person and the limit range of the drawer.

[0088] In the embodiment of the present disclosure, the limit range is the space range occupied by the drawer when it is fully opened. Figure 4 An exemplary schematic diagram showing the limit range of the drawer of an electrical device is shown. Figure 4 In the figure, the rectangular area B represents the limit range of the drawer.

[0089] S504: When the drawer control device detects that the person is outside the limit range of the drawer, it controls the drawer to fully open.

[0090] When a person is outside the limit range of the drawer, it means that the drawer will not touch the person even if it is fully opened. Therefore, the drawer control device can control the drawer to be fully opened, making it more convenient for the user to store or take out items.

[0091] S505: When the drawer control device detects that a person is within the limit range of the drawer, it determines a safe distance based on the distance between the person and the drawer, and controls the drawer to extend to the safe distance.

[0092] When a person is within the drawer's limit range, it indicates that fully opening the drawer will cause contact with the person. Therefore, when a person is detected within the drawer's limit range, a safe distance is determined based on the distance between the person and the drawer. The safe distance is less than the distance the drawer extends when fully opened. After determining the safe distance, the drawer control device controls the drawer to extend the safe distance to prevent contact with the person.

[0093] In the disclosed embodiment, a minimum distance between a person and a drawer can be determined. The difference between the minimum distance and a preset safety distance value is then calculated and used as the safety distance. The safety distance value can be determined based on actual design requirements. For example, the safety distance value can be 3 cm, 5 cm, or 8 cm.

[0094] S506: When the drawer control device detects no person in the effective triggering range of the electrical device, the drawer is controlled to remain closed.

[0095] In some embodiments, when a person is detected within the limit range of a drawer, a safe distance is determined based on the distance between the person and the drawer, and the drawer is controlled to extend to the safe distance, including: when a person is detected within the limit range of the drawer, the safe distance and a safe extension speed are determined based on the distance between the person and the drawer; and the drawer is controlled to extend to the safe distance at the safe extension speed. The safe extension speed is less than the normal extension speed of the drawer.

[0096] As mentioned above, when a person is within the limit range of the drawer, it indicates that the drawer will touch the person when it is fully opened. In order to ensure safety, the drawer can be controlled to extend at a lower speed (such as a safe extension speed) at this time. Specifically, the safe extension speed is proportional to the distance between the person and the drawer, that is, the greater the distance between the person and the drawer, the greater the safe extension speed, wherein the safe extension speed is less than the normal extension speed of the drawer. Therefore, a conversion relationship between the safe extension speed and the distance between the person and the drawer can be set. When it is detected that a person is within the limit range of the drawer, the safe extension speed can be determined based on the distance between the person and the drawer and the conversion relationship, and then the drawer can be controlled to extend a safe distance at the safe extension speed.

[0097] In some embodiments, after controlling the drawer to extend at a safe extension speed and a safe distance, the system further includes: if it is determined that the drawer has been extended by the safe distance, re-detecting the positional relationship between the person and the drawer's limit range; and if the person is detected to be outside the drawer's limit range, controlling the drawer to fully open. If the person is detected to be outside the drawer's limit range, the system continues to control the drawer to fully open, eliminating the need for the user to manually fully open the drawer and making it more convenient for the user to store or retrieve items.

[0098] In some embodiments, after controlling the drawer to extend to a safe distance at a safe extension speed, the system further includes: upon determining that the drawer has been extended to the safe distance, re-detecting the positional relationship between the person and the drawer's limit range; and upon detecting that the person is within the drawer's limit range, issuing a door opening completion message. If the drawer has been extended to the safe distance, but the person is still within the drawer's limit range, the drawer edge will no longer extend, and a door opening completion message will be issued. The door opening completion message can be a voice message, which is used to inform the user that the automatic drawer opening process has ended, prompting the user not to wait for the drawer to continue opening, so that the user can store or retrieve items as quickly as possible.

[0099] In some embodiments, after controlling the drawer to open, it also includes: when it is determined that the time the drawer remains open exceeds a first opening time threshold, re-continuously detecting whether there is anyone within the effective triggering range of the electrical device; when no one is detected within the effective triggering range of the electrical device within a second preset time period, controlling the drawer to close; when it is detected that someone is within the effective triggering range of the electrical device within the second preset time period, controlling the drawer to remain open and issuing a door closing prompt message, and the door closing requirement inquiry information is used to prompt the user to close the drawer in time.

[0100] like Figure 6 As shown, the embodiment of the present disclosure provides another drawer control method for an electrical device, the control method is a drawer control device, and the control method includes the following steps:

[0101] S601: When the drawer of the electrical device is closed, the drawer control device determines that a specific type of sound exists in the environment of the electrical device, compares the sound intensity with the intensity threshold, and matches the voiceprint feature of the sound with the standard feature.

[0102] S602: When determining that the sound intensity is greater than the intensity threshold and the voiceprint feature is a standard feature, the drawer control device detects whether there is a person within the effective triggering range of the electrical device.

[0103] S603: When the drawer control device detects that there is a person in the effective triggering range of the electrical device, it controls the drawer to open.

[0104] S604: When the drawer control device determines that the time for which the drawer remains open exceeds the first opening time threshold, the drawer control device continues to detect whether there is anyone within the effective triggering range of the electrical device.

[0105] S605: When the drawer control device does not detect anyone in the effective triggering range of the electrical device within the second preset time period, the drawer control device controls the drawer to close.

[0106] S606: When the drawer control device detects that there is someone in the effective triggering range of the electrical device within the second preset time period, it controls the drawer to remain open and issues a door closing prompt message.

[0107] In the embodiment of the present disclosure, in order to prevent the drawer from being opened for a long time due to the user forgetting to close the drawer, the embodiment of the present disclosure sets a first opening time threshold and a second preset time. The drawer control device can count the time the drawer remains open in real time. When the drawer control device determines that the time the drawer remains open exceeds the first opening time threshold, it will continue to detect whether there is anyone within the effective trigger range of the electrical device within the second preset time. If no one is detected within the effective trigger range of the electrical device within the second preset time, the drawer can be controlled to close; if someone is detected within the effective trigger range of the electrical device within the second preset time, the drawer is controlled to remain open and a door closing prompt message is issued. The door closing requirement inquiry message is used to prompt the user to close the drawer in time. For example, the door closing requirement inquiry message can be a voice message, and the door closing requirement inquiry message can be "The drawer has been open for a long time, please pay attention to close the drawer."

[0108] S607: When the drawer control device detects no person in the effective triggering range of the electrical device, the drawer is controlled to remain closed.

[0109] In some embodiments, after controlling the drawer to remain open and issuing a door closing prompt message, the method further includes: when it is determined that the time for which the drawer remains open exceeds a second opening time threshold, controlling the drawer to close.

[0110] To further prevent a drawer from remaining open for extended periods due to the user forgetting to close it, the disclosed embodiment provides a second open time threshold, which is greater than the sum of the first open time threshold and a second preset time duration. The drawer control device can count the time the drawer remains open in real time and, if it determines that the drawer has remained open for longer than the second open time threshold, directly control the drawer to close.

[0111] In some embodiments, when it is determined that the drawer remains open for a time exceeding a second opening time threshold, the drawer is controlled to close, including: when it is determined that the drawer remains open for a time exceeding the second opening time threshold, a door closing confirmation message is issued; when it is determined that a specific type of sound exists in the environment where the electrical device is located within a third preset time period, the sound intensity of the sound is compared with the intensity threshold, and the voiceprint feature of the sound is matched with the standard feature, and when it is determined that the sound intensity is greater than the intensity threshold and the voiceprint feature belongs to the standard feature, the drawer is controlled to remain open; when it is determined that no specific type of sound exists in the environment where the electrical device is located within the third preset time period, the drawer is controlled to close.

[0112] In the embodiment of the present disclosure, the door closing confirmation message is used to prompt the user to make a specific type of sound again to keep the drawer open. As mentioned above, the specific type of sound can be the sound of the user knocking on the drawer, the sound of the user containing a voice command (such as "open the door"), the user's cough, etc. When the drawer control device determines that the time the drawer remains open exceeds the second opening time threshold, it issues a door closing confirmation message. After that, if a sound signal sent by the sound collection module is received within a third preset time period, it can determine whether the sound collected by the sound collection module is a specific type of sound based on the sound signal.

[0113] It can be understood that if the user makes a specific type of sound within the third preset time period, the drawer control device can determine that a specific type of sound exists in the environment where the electrical device is located within the third preset time period, and then compare the sound intensity of the sound with the intensity threshold, and match the voiceprint characteristics of the sound with the standard characteristics, and control the drawer to remain open when it is determined that the sound intensity is greater than the intensity threshold and the voiceprint characteristics belong to the standard characteristics. If the user does not make a specific type of sound within the third preset time period, the drawer control device controls the drawer to close when it determines that a specific type of sound does not exist in the environment where the electrical device is located within the third preset time period.
