The image acquisition device 21 may be arranged in a plurality of orientations within the dishwasher 100. The processing device 24 may be electrically connected to the image acquisition device 21.
The image acquisition device 21 may be used to acquire images within the dishwasher 100 and the processing device 24 may be used to process the acquired images.
For example, the image acquisition device 21 may acquire an image of the cutlery on the rack 22 after the cutlery is placed on the rack 22. The processing device 24 can acquire the image, determine characteristics of the dishes placed in the dishwasher 100, and control the spray arm to wash the dishes based on the characteristics of the dishes.

In another example, the spray arm may be disposed at the top within the dishwasher 100, or may include a spray arm at the top and a spray arm at the bottom.
In yet another example, the spray arm may take a rotatable form.
Fig. 1C schematically illustrates a structural schematic view of a washing mechanism of a dishwasher according to an embodiment of the present invention; fig. 1D schematically shows a partial schematic structure of the cleaning mechanism of fig. 1C. Referring to fig. 1B-1D, the washing mechanism 2 may further include a driving motor 23, and the driving motor 23 may be disposed at a lower side in the dishwasher 100 or may be disposed at a rear surface of the dishwasher 100, i.e., a surface far from a user to place dishes. The drive motor 23 may be connected to the spray arm 25. The spray arm 25 is provided with spray holes 251 communicated with the inside of the spray arm 25, and the spray holes 251 can be arranged on the spray arm 25 at intervals so that the spray arm 25 sprays a larger range. In one example, the spray arm 25 may be cylindrical, and the spray holes 251 are spaced apart and arranged in an array in a cross section of the spray arm 25 such that water sprayed from the spray holes 251 is sprayed at an angle.
In an embodiment of the present invention, the dishwasher 100 may further include a water pressure transmitter (not shown), a water heater (not shown), and a water valve (not shown).

Fig. 2 schematically shows a flow chart of a control method for a dishwasher according to an embodiment of the present invention, as shown in fig. 1, in an embodiment of the present invention, there is provided a control method for a dishwasher, comprising the steps of:
in step 201, in the case that the voice module detects that the user makes a sound, the direction of the sound is determined.
The dishwasher comprises a voice module, the voice module can detect the sound emitted by the user, and the processor can determine the direction of the sound according to the detected sound under the condition that the voice module is determined to detect the sound emitted by the user.
In one embodiment, the voice module includes a plurality of microphones, and in the event that the voice module detects a user uttering a sound, determining the direction of the sound includes: receiving first sound signals corresponding to sounds collected by the plurality of microphones in a plurality of directions when any microphone in the plurality of microphones detects that a user emits sounds; determining a microphone with the largest collected sound among the plurality of microphones according to the first sound signal; the direction of the microphone with the largest collected sound is determined as the sound direction.
In one embodiment, the number of microphones is at least 4, and 4 sounds in different directions 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.
Under the condition that the voice module detects the sound emitted by a user, the direction of the sound can be determined according to the detected sound, the voice module of the dish washer comprises a plurality of microphones, and the processor can control the microphones on the voice module to start working under the condition that any one of the microphones of the voice module detects the sound emitted by the user, so that first sound signals collected by the microphones in a plurality of directions are received. 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 signal with the largest sound and the microphone corresponding to the first sound signal. And after the microphone that collects the maximum sound is determined, the collection direction of the microphone is determined as the direction of the sound. The number of microphones mounted on the voice module is at least 4, and the acquisition range of each microphone is an area formed by a radius of 1 meter and a central angle of 150 degrees. The microphone can collect 4 sounds in different directions respectively.
For example, assume that four microphones are mounted on the voice module and face different directions respectively 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 event that any one of the four microphones detects a user's uttered sound, the processor may begin receiving the corresponding first sound signals acquired by the four microphones in the direction of the respective coverage. The processor judges the largest sound and the corresponding microphone in the sound collected by each microphone according to the received first sound signal, and determines the corresponding direction of the microphone as the direction of the sound.
Step 202, tracking the sound according to the direction of the sound to determine the movement direction of the user.
After determining the direction of the sound source, the processor may track the sound based on its direction to determine the direction of movement of the user.
In one embodiment, tracking sound based on the direction of the sound to determine the direction of movement of the user includes: controlling the microphone with the largest collected sound to track the sound; receiving a second sound signal corresponding to the sound continuously collected by the microphone with the largest collected sound; determining that the user moves in a direction approaching the dishwasher under the condition that the frequency of the sound is gradually increased and the volume of the sound is gradually increased according to the second sound signal; in case it is determined that the frequency of the sound is gradually slowed down 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.
After determining the direction of the sound, the processor may track the sound according to the direction of the sound, thereby determining the direction of movement of the user by tracking the sound. The processor can control the microphone with the largest collected sound to track the sound, and can receive a second sound signal corresponding to the sound continuously collected by the microphone with the largest collected sound. As the pler effect indicates, the reception frequency becomes higher when the wave source moves closer to the observer and becomes lower when the wave source moves away from the observer. Therefore, when the object approaches the sound source, the relative distance is changed, the frequency is changed, the speed of the user can be obtained by calculating the sound frequency and the air sound velocity, and the position of the follow-up sound source can be obtained at the position close to or far from the object. 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 sound frequency of the second sound signal is gradually faster and the volume of the sound is gradually greater. The processor may determine that the user moves in a direction away from the dishwasher in case it is determined that the sound frequency of the second sound signal gradually becomes slow and the volume of the sound gradually becomes smaller.
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 203.
In one embodiment, controlling the rotational speed reduction of the motor includes: the rotational speed of the motor is controlled to be reduced to 20rad/s.
The processor may determine whether the user is moving in a direction away from the dishwasher or in a direction closer to the dishwasher by detecting the second acoustic signal. In the case where the processor determines that the user moves toward the dishwasher, the processor may control the rotation speed of the motor to be reduced. The processor may control the rotational speed of the motor to be reduced to 20rad/s. Because dish washer can rotate along with the drive of motor at the in-process of washing tableware, opens the door when the motor does not stop and gets the tableware, and the motor stops the operation this moment, but rotatory cantilever can spray the water of dish washer on one's body the user because of inertia, brings bad experience for the user. Therefore, in the embodiment, when the processor determines that the user moves towards the direction approaching the dish washer, the processor controls the rotation speed of the motor to be reduced in advance, so that the rotation speed of the motor is reduced to 20rad/s, and water spraying caused by inertia of the cantilever when the user opens the door is prevented.
In one embodiment, in case it is determined that the user moves in a direction approaching the dishwasher and the user moves in a direction of the motor, an opened state of a door of the dishwasher is detected; and controlling the motor to stop running under the condition that the door of the dish washer is detected to be in an open state.
In one embodiment, the motor is controlled to increase in rotation speed in the 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 processor may control the motor to decrease the rotation speed when it is determined that the user moves toward the dishwasher, and the processor may detect an opened state of the door of the dishwasher in case it is determined that the user moves toward the dishwasher and the user moves toward the motor. If the user opens the door, the processor judges that the door of the dish washer is in an opened state at the moment, and controls the motor to stop running so that the dish washer pauses washing. Since the rotation speed of the motor of the dishwasher has been reduced in advance, the cantilever driven by the motor will not splash water to the user due to inertia even if the user opens the door and the motor stops running.
Because the user may only pass the situation near the dish washer, if the user does not open the door and does not open the door within a preset time, that is, the processor does not detect that the door of the dish washer is in an open state within the preset time, and meanwhile, the processor can control the rotation speed of the motor to increase under the condition that no sound is detected within the preset time, so that the normal washing behavior of the dish washer is maintained. Because the user may be in the vicinity of the microphone of the dishwasher to perform other works, the processor can continuously detect the sound when the processor does not detect that the door of the dishwasher is in an open state within the preset time, and if the sound is always in the detection range but the door of the dishwasher is not opened within the preset time, the processor can also control the rotation speed of the motor to increase so as to keep the normal washing behavior of the dishwasher.
For example, the processor may control the motor to decrease the rotation speed when determining that the user moves in a direction approaching the dishwasher by detecting the second sound signal, and if the door of the dishwasher is opened by the user at this time, the processor controls the motor to stop operating, so that the dishwasher pauses washing. Because the processor has controlled the motor to rotate at a reduced speed when the user approaches the dishwasher, the user can avoid splashing of water by the dishwasher due to the inertia of the cantilever when opening the door. If the user is close to the dishwasher but within the preset time, assuming the preset time to be 3 minutes, there is no door opening action within 3 minutes, and meanwhile, no sound activity, the processor can control the rotation 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 remains unchanged in case it is determined that the user moves in a direction away from the dishwasher.
The processor determines that the user is in a state of moving away from the dish washer at the moment through detecting the second sound signal, namely, no action of opening the dish washer by the user exists, and in order not to influence normal washing of the dish washer, the processor can control the rotating speed of the motor to be unchanged at the moment, so that normal operation of the dish washer is maintained.
In one embodiment, a processor is provided that is configured to perform the control method for a dishwasher of any one of the above.
As shown in fig. 3, a flow chart schematically illustrating a control method for a dishwasher according to an embodiment of the present application includes the steps of:
step 301, the dishwasher is started.
Step 302, sound detection.
Step 303, sound source direction localization.
Step 304, footstep sound tracking.
Step 305, user motion localization.
Step 306, it is determined that the user is approaching or moving away, and if it is determined that the user is moving away, step 307 is entered, and if it is determined that the user is approaching, step 308 is entered.
Step 307, maintaining the dishwasher speed.
Step 308, reducing the dishwasher speed.
Step 309, determining whether the door of the dishwasher is in a door-open state, determining that the door of the dishwasher is in a door-open state, entering step 310, determining that the door of the dishwasher is in a door-unopened state, and entering step 311.
Step 310, pausing the cleaning.
Step 311, determining that there is no footstep sound for more than three minutes.
Step 312, increasing the rotational speed maintains the purge.
Step 313, the dishwasher ends the operation.
The dishwasher comprises a voice module and a motor, wherein the voice module comprises a plurality of microphones. The dish washer starts work, and the voice module can detect user's sound through the microphone, and the quantity of the microphone that includes on the voice module is 4 at least, gathers 4 different directional sounds respectively, and the acquisition scope of every microphone is radius 1 meter, and the central angle is 150 degrees regional scope. The processor may determine a sound direction based on the detected sound in the event that the voice module is determined to detect the sound of the user.
And the processor can control all the microphones on the voice module to collect the voice under the condition that any microphone on the voice module detects the voice of the user. And detecting the collected sound of 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 four microphones A, B, C, D for collecting sounds in different directions, and when the microphone a detects sounds, the processor can control A, B, C, D the four microphones to start collecting sounds in the receiving range of the microphone. The processor is assumed to determine that the sound picked up by the B microphone is the largest by detecting the sound picked up by each microphone. The processor may determine the direction of the sound source based on the pickup direction of the B microphone.
The microphone collects mainly the footstep sound of the user, and other sounds of the user, such as speaking sounds, can also be collected when the footstep sound of the user is collected. When the processor positions the sound source direction of the sound according to the microphone, the processor can keep away according to the Doppler effect and track the footstep sound of the user, so that the movement direction of the user is judged. The processor can analyze and detect the user footstep sound continuously collected by the sound transmitter, and can position the movement of the user under the condition that the sound frequency of the collected footstep sound is gradually increased and the volume of the footstep sound is gradually increased, and can judge that the user is approaching to the dish washer. If the processor analyzes and detects the footstep sound continuously collected by the microphone, and the sound frequency of the collected footstep sound is gradually slowed, and the processor can judge that the user is far away from the dish washer at the moment when the sound volume of the footstep sound is gradually reduced.
The processor may control the motor of the dishwasher to maintain a rotational speed in the event that the user is located away from the dishwasher, i.e. the dishwasher may maintain a normal washing condition until the dishwasher is finished. When a user is in a 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 sprays water of the dishwasher to the user due to inertia, thereby bringing bad experience to the user. The processor can pre-judge the door opening behavior of the user in advance according to the collected user footstep sound, water spraying is prevented, and user experience is improved. Therefore, when the processor determines that the user is approaching the dish washer, the processor can control the rotation speed of the motor of the dish washer to be reduced, and the processor can reduce the rotation speed of the motor to 20rad/s, so that even if the user suddenly performs a door opening operation, the cantilever can not spray water to the user due to inertia when the motor stops rotating along with the door opening of the user due to the lower rotation speed of the motor. The processor may also detect whether a door opening operation has been performed by the user. If the user performs the door opening operation, the processor can control the motor to stop and pause the washing work of the dish washer under the condition that the processor detects that the door of the dish washer is in the door opening state.
If the user does not open the door, the processor detects that the door of the dish washer is in a non-open state, and the processor can continuously collect and analyze the footstep sound of the user. The processor may set the preset time to be three minutes, and if the processor does not detect the footstep sound of the user within 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 during the conventional washing, so that the dishwasher may continue the conventional washing.
As there may be a possibility that the user is in the vicinity of the dishwasher to perform other tasks. The processor may also control the rotation speed of the dishwasher to be increased to the rotation speed at the time of the conventional washing in case that it is detected that the footstep sound of the user 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 may continue the conventional washing work. After the dish washer finishes the normal cleaning work, the work can be ended and the dish washer is closed.
Through the technical scheme, the voice of the user is collected through the microphone included in the dish washer voice module, the voice is judged through detecting the voice of the user, and the voice of the user is tracked and positioned. When the processor determines that the user is close to the dish washer, the motor rotation speed of the dish washer is reduced, and water spraying caused by inertia of the cantilever when the user opens the door is prevented, so that bad use experience is brought to the user. And when the door opening behavior of the user exceeds the preset time is judged, the dishwasher can restore the conventional dishwashing operation. The dishwasher not only avoids splashing of water caused by sudden opening of the door by a user, but also can keep normal operation of the dishwasher when the user does not perform door opening operation. And other problems that may exist are also considered, for example, if the user is merely walking through the dishwasher, but the dishwasher may slow down the motor when the user is detected to be close to the dishwasher. The processor may also set a preset time for controlling the rotation speed of the dishwasher motor to be increased to a normal washing state when the user does not open the door and the microphone detection range does not detect the sound of the user.
