Fig. 2 schematically shows a flow chart of a control method for a dishwasher according to an embodiment of the present invention, and as shown in fig. 1, in an embodiment of the present invention, there is provided a control method for a dishwasher, including the steps of:
in step 201, in the case that the voice module detects that the user utters a voice, the direction of the voice is determined.
The dishwasher includes a voice module that detects a sound emitted by a user, and the processor determines a direction of the sound based on the detected sound if it is determined that the voice module detects the sound emitted by the user.
In one embodiment, the speech module comprises a plurality of microphones, and in the event that the speech module detects that the user uttered sound, determining the direction of the sound comprises: receiving first sound signals corresponding to sounds collected by a plurality of microphones in a plurality of directions under the condition that any microphone in the plurality of microphones detects that a user sends a sound; determining a microphone with the largest sound collected in the plurality of microphones according to the first sound signal; and determining the collecting direction of the microphone with the largest collected sound as the direction of the sound.
In one embodiment, the number of microphones is at least 4, and 4 different directions of sound are collected respectively.
In one embodiment, the acquisition range of each microphone is an area with a radius of 1 meter and a central angle of 150 degrees.
The dishwasher comprises a dishwasher, a voice module and a processor, wherein the voice module can determine the direction of sound according to the detected sound when detecting the sound emitted by a user, the voice module of the dishwasher comprises a plurality of microphones, and the processor can control the plurality of microphones on the voice module to start working when determining that any one of the plurality of microphones of the voice module detects the sound emitted by the user, so as to receive first sound signals collected by the plurality of microphones in a plurality of directions. After the processor receives the first sound signals, the processor can judge the first sound signals collected by each microphone, and determine the first sound signals with the maximum sound and the corresponding microphones. And determining the collecting direction of the microphone as the direction of the sound after determining the microphone collecting the maximum sound. The number of the microphones installed on the voice module is at least 4, and the acquisition range of each microphone is an area formed by the radius of 1 meter and the central angle of 150 degrees. The microphones can respectively collect 4 sounds in different directions.
For example, assume that four microphones are installed on the voice module, and the microphones are respectively oriented to different directions to collect sounds in different directions, and the collection range of each microphone is an area formed by a radius of 1 meter and a central angle of 150 degrees. In the case where any one of the four microphones detects a sound emitted by the user, the processor may start receiving corresponding first sound signals collected by the four microphones in the directions of the respective covers. The processor judges the maximum sound and the corresponding microphone in the sound collected by each microphone according to the received first sound signal, and determines the direction corresponding to the microphone as the direction of the sound.
The processor, having determined the direction from which the sound originated, may track the sound based on its direction, thereby determining the direction of movement of the user.
In one embodiment, tracking the sound according to the direction of the sound to determine the direction of movement of the user comprises: controlling a microphone with the maximum collected sound to track the sound; receiving a second sound signal corresponding to the sound continuously collected by the microphone with the maximum collected sound; determining that the user moves in a direction approaching the dishwasher in case that it is determined that the frequency of the sound becomes gradually faster and the volume of the sound becomes gradually larger according to the second sound signal; in case it is determined that the frequency of the sound is gradually slowed and the volume of the sound is gradually decreased according to the second sound signal, it is determined that the user moves in a direction away from the dishwasher.
The processor can track the sound according to the direction of the sound after determining the direction of the sound, so that the movement direction of the user can be determined through the tracking of the sound. The processor can control the microphone with the largest collected sound to track the sound, and the processor can receive a second sound signal corresponding to the sound collected continuously by the microphone with the largest collected sound. The doppler effect indicates that the wave has a higher frequency of reception when the source moves closer to the observer and a lower frequency of reception when the source moves farther away from the observer. Therefore, when an object approaches a sound source, the relative distance changes, the frequency changes, the speed of the user can be obtained by calculating the sound frequency and the air sound velocity, and the position close to or far away from the object can be obtained by following the position of the sound source. The processor, upon receiving the second sound signal, may determine a change in sound frequency and a change in sound volume by detecting the second sound signal. The processor may determine that the user moves in a direction approaching the dishwasher at this time in a case where it is determined that the frequency of the sound of the second sound signal is gradually faster and the volume of the sound is gradually greater. The processor may determine that the user is moving away from the dishwasher in a case where it is determined that the frequency of the sound of the second sound signal is gradually slowed and the volume of the sound is gradually decreased.
In case it is determined that the user moves in a direction approaching the dishwasher, the rotational speed of the motor is controlled to be reduced, step 203.
In one embodiment, controlling the reduction in the rotational speed of the motor comprises: the rotation speed of the motor is controlled to be reduced to 20 rad/s.
The processor can judge whether the user moves away from the dishwasher or moves close to the dishwasher through the detection of the second sound signal. In case the processor determines that the user is moving in a direction close to the dishwasher, the processor may control the rotational speed of the motor to be reduced. The processor can control the rotating speed of the motor to be reduced to 20 rad/s. Because dish washer is at the in-process of washing tableware, the cantilever can be rotatory along with the drive of motor, opens the door when the user does not stop at the motor and gets the tableware, and the motor can the bring not good experience for the user because inertia sprays the user on one's body with dish washer's water by rotatory cantilever this moment. Therefore, in this embodiment, when the processor determines that the user moves towards the direction close to the dishwasher, the processor controls the rotation speed of the motor to be reduced in advance to reduce the rotation speed of the motor to 20rad/s, so as to prevent the user from spraying water due to the inertia of the cantilever when opening the door.
In one embodiment, in case it is determined that the user moves in a direction of approaching the dishwasher and the user moves in a direction of the motor, an open state of a door of the dishwasher is detected; and controlling the motor to stop running under the condition that the door of the dishwasher is detected to be in an open state.
In one embodiment, in case that the door of the dishwasher is not detected to be in an open state for a preset time and no sound is detected, the rotation speed of the motor is controlled to be increased.
The processor may control the motor to decrease the rotation speed when it is determined that the user moves in a direction approaching the dishwasher, and the processor may detect an open state of a door of the dishwasher in a case where the processor determines that the user moves in a direction approaching the dishwasher and the user moves in a direction of the motor. If the user opens the door, the processor judges that the door of the dishwasher is in an open state at the moment, and controls the motor to stop running so that the dishwasher suspends cleaning. Since the dishwasher has lowered the rotational speed of the dishwasher motor in advance, even if the user stops the operation of the door-opening motor, the cantilever driven by the motor does not splash water to the user due to inertia.
Because the situation that the user just passes by the vicinity of the dishwasher may exist, if the user does not open the door and does not perform the door opening operation within the preset time, that is, the processor does not detect that the door of the dishwasher is in the open state within the preset time, and meanwhile, under the situation that the sound is not detected within the preset time, the processor can control the rotation speed of the motor to be increased, and the normal washing behavior of the dishwasher is maintained. Because the user may be in the vicinity of the microphone of the dishwasher to perform other work, the processor may continuously detect the sound when the processor does not detect that the door of the dishwasher is in an open state within a preset time, and if the sound is always in a detection range but the door of the dishwasher is not opened within the preset time, the processor may also control the rotation speed of the motor to increase, so as to maintain the normal washing behavior of the dishwasher.
For example, the processor detects the second sound signal, the user moves towards the direction close to the dishwasher, and the processor controls the motor to reduce the rotating speed when determining that the user moves towards the direction close to the dishwasher, and if the user opens the door of the dishwasher at the moment, the processor controls the motor to stop running, so that the dishwasher suspends washing. Since the processor already controls the motor to decrease in speed when the user approaches the dishwasher, the user can avoid water splashing from the dishwasher due to the inertia of the cantilever when opening the door. If the user approaches the dishwasher but within the preset time, the preset time is assumed to be 3 minutes, no door opening action is required within 3 minutes, and no sound activity is available, the processor can control the rotating speed of the motor to increase, so that the normal washing action of the dishwasher is maintained.
In one embodiment, the rotational speed of the control motor is kept constant in case it is determined that the user is moving away from the dishwasher.
The processor determines that the user is in a state of moving away from the dishwasher at the moment through the detection of the second sound signal, namely, the action of opening the dishwasher by the user does not exist, and in order to not influence the normal washing of the dishwasher, the processor can control the rotating speed of the motor to be kept unchanged at the moment, and the normal work of the dishwasher is maintained.
In one embodiment, a processor is provided that is configured to perform any of the above-described control methods for a dishwasher.
As shown in fig. 3, a flow chart of a control method for a dishwasher according to an embodiment of the present application is schematically shown, including the following steps:
in step 301, the dishwasher is started.
At step 310, the cleaning is suspended.
In step 313, the dishwasher ends the operation.
The dishwasher includes a voice module and a motor, wherein the voice module includes a plurality of microphones. The dishwasher is started to work, the voice module can detect the voice of a user through the microphones, the number of the microphones included on the voice module is at least 4, the microphones collect 4 voices in different directions respectively, the collection range of each microphone is an area range with the radius of 1 meter and the central angle of 150 degrees. The processor may determine the sound direction based on the detected sound in a case where it is determined that the voice module detects the sound of the user.
The processor can control all the microphones on the voice module to collect the sound under the condition that any one of the microphones on the voice module detects the sound of the user. And detecting the sound collected by all the microphones, determining which microphone collects the largest sound, and determining the collection direction of the microphone as the sound source direction of the sound. For example, the voice module includes A, B, C, D four microphones for collecting sounds in different directions, and when the microphone a detects a sound, the processor can control A, B, C, D four microphones to start collecting sounds within the microphone receiving range. The processor is assumed to judge that the sound collected by the B microphone is the maximum by detecting the sound collected by each microphone. The processor may determine the direction of the sound source based on the acquisition direction of the B microphone.
The microphone collects the footstep sound of the user mainly, and other sounds of the user, such as speaking sounds, can also be collected when the footstep sound of the user is collected. After the processor positions the sound source direction of the sound according to the microphone, the processor can trace the footstep sound of the user according to the Doppler effect, so that the movement direction of the user is judged. The processor can analyze and detect the user's footstep sounds continuously collected by the microphone, and under the condition that the sound frequency of the collected footstep sounds is gradually increased and the volume of the footstep sounds is gradually increased, the processor can position the movement of the user, and at the moment, the user can be judged to be approaching the dishwasher. If the processor analyzes and detects the footstep sound continuously collected by the microphone, and determines that the sound frequency of the collected footstep sound gradually becomes slow and the volume of the footstep sound gradually decreases, the processor can judge that the user is far away from the dishwasher at the moment.
The processor determines that the user is in a situation of being away from the dishwasher, may control the motor of the dishwasher to maintain the rotation speed, i.e., the dishwasher may maintain the regular washing state until the operation of the dishwasher is finished. When the user is in the condition of approaching the dishwasher, at this time, the user may perform a door opening operation, and in order to prevent the user from opening the door, the cantilever of the dishwasher causes water of the dishwasher to splash the user due to inertia, which brings a bad experience to the user. The treater can be according to the user's step sound of gathering, and the action of opening the door of prejudgement user prevents to spray water, promotes user experience in advance. Therefore, in case that the processor determines that the user is approaching the dishwasher, the processor may control the rotational speed of the motor of the dishwasher to be reduced, and the processor may reduce the rotational speed of the motor to 20rad/s, so that even if the user suddenly performs a door opening operation, the cantilever does not splash water onto the user due to inertia when the motor stops rotating as the user opens the door due to the low rotational speed of the motor. The processor may also detect whether a door opening operation is performed by the user. If the user opens the door, the processor can control the motor to stop and suspend the washing work of the dish washing machine under the condition that the processor detects that the door of the dish washing machine is in the door opening state.
If the user does not open the door, the processor detects that the door of the dishwasher is in a non-opening state, and the processor can continue to collect and analyze the footstep sound of the user. The processor may set the preset time to three minutes, and if the processor does not detect the step sound of the user in three minutes, that is, the current situation may be that the user passes near the dishwasher, the processor may control the rotation speed of the motor to be increased to the rotation speed at the time of the regular washing so that the dishwasher may continue the regular washing work.
As there may be the possibility that the user is in the vicinity of the dishwasher for other work. The processor may also control the rotation speed of the dishwasher to be increased to the rotation speed at the time of the regular washing in case that it is detected that the user's footstep sound is within the detection range of the microphone but the door of the dishwasher is not opened for more than three minutes, so that the dishwasher can continue the regular washing work. After the dishwasher finishes the normal cleaning work, the dishwasher can finish the work and close the dishwasher.
Through above-mentioned technical scheme, collect user's sound through the microphone that includes at dishwasher voice module to judge the angry of sound through the sound that detects user, and track and fix a position user's sound. When the treater confirms that the user is close to dish washer, reduce the motor speed of dish washer, cantilever leads to the water spray because of inertia when preventing that the user from opening the door to bring not good use for the user and experience. And the dishwasher can recover the conventional dish washing operation when judging that the user does not perform the action of opening the door after exceeding the preset time. Not only prevents the user from being splashed by water due to sudden opening of the door, but also can keep the dishwasher working normally when the user does not perform the door opening operation. And also other problems that may exist, such as if the user just passes by the dishwasher, but the dishwasher slows down the motor when the user is detected to be close to the dishwasher. The processor may further set a preset time for controlling the rotation speed of the motor of the dishwasher to increase to a normal washing state when the user does not open the door and the user's voice is not detected in the detection range of the microphone within the preset time.
