It is understood that the refrigerator may receive a control instruction sent by a user through the controller 40, and in some embodiments, the controller 40 may include: network interface, user interface, memory, communication bus. Wherein the communication bus is used for realizing connection communication among the components. The user interface may include a Display screen (Display), an input unit such as a remote controller or a voice control unit, and may further include a standard wired interface and a standard wireless interface, and when in specific use, the front end acquires data through the user interface. The network interface may optionally include a standard wired interface, a wireless interface (e.g., WI-FI interface).
Referring to fig. 3, in a first embodiment of a door control method of a refrigerator provided by the present invention, the door control method of the refrigerator includes the steps of:
step S10, acquiring a box door control instruction sent by a user, and controlling the electric control rotating shaft to rotate according to a set rotating speed corresponding to the control instruction according to the control instruction so as to enable the box door to rotate to a set angle corresponding to the control instruction;
in this embodiment, the step of acquiring the box door control instruction sent by the user may be:
and acquiring a voice-based box door control instruction or a remote-control-based box door control instruction sent by a user.
Specifically, the user may send the door control instruction through the remote controller, for example, the remote controller may be provided with a door opening key and a door closing key, and the user may send the control instruction to the controller by directly pressing the corresponding keys. Alternatively, the user may directly speak a voice like "open door" or "close door" to be received by the controller of the refrigerator.
In this embodiment, the control command includes door opening and closing information, door speed information, and door angle information. The door opening and closing information comprises opening or closing of the door; the box door speed information can be a set rotating speed preset by a user and stored in a memory; the door angle information may be a set angle preset by a user and stored in the memory. The electronic control rotating shaft can be controlled to rotate towards a preset door opening direction or a preset door closing direction according to a set rotating speed by acquiring the door opening and closing information, the door speed information and the door angle information in the control instruction, so that the door rotates to a set angle.
Step S20, acquiring the current rotating speed of the box door, and judging whether the current rotating speed of the box door is matched with the set rotating speed;
it should be noted that, in the process that the box door rotates to a set angle according to a set rotating speed, the controller obtains the current rotating speed of the box door in real time, and judges whether the current rotating speed of the box door is matched with the set rotating speed, so as to monitor the rotating speed of the box door. When the current rotating speed of the box door is the same as or basically the same as the set rotating speed, the current rotating speed of the box door is judged to be matched with the set rotating speed.
Step S30, if not, acquiring the current angle of the box door, and judging whether the current angle of the box door is matched with the set angle;
in a preferred embodiment of the present invention, the set rotation speed of the door includes a first door speed and a second door speed, and the set angle of the door includes a first door angle and a second door angle when the door opening/closing information is to open the door.
It can be understood that, when the control command includes the opening and closing information of the door, the set rotation speed of the door, and the set angle of the door, the control command may specifically be at least one of the following:
opening the door to a first door angle at a first door speed;
opening the door to a second door angle at a first door speed;
opening the door to a first door angle at a second door speed;
opening the door to a second door angle at a second door speed;
closing the door at a first door speed;
closing the door at a second door speed.
For example, the set rotating speed is a first box door speed, the electric control rotating shaft rotates according to the first box door speed corresponding to the control instruction, in the box door rotating process, a user carelessly touches the box door to change the rotating speed of the box door, at this time, the current rotating speed of the box door is judged to be not matched with the first box door speed, the current rotating angle of the box door is further obtained, and whether the current angle of the box door is matched with the set angle is judged. When the current angle of the box door is the same as or basically the same as the set angle, the current angle of the box door is judged to be matched with the set angle.
And step S40, if yes, controlling the electric control rotating shaft to stop rotating.
Further, when the current angle of the refrigerator door is judged to be equal to the set angle, which indicates that the refrigerator door rotates to the set angle corresponding to the control instruction at the moment, the electric control rotating shaft is controlled to stop rotating, and a user can conveniently control the refrigerator.
For example, in the rotation process of the box door, the box door is forced to rotate by a certain angle due to the occurrence of intervention actions such as turning the body of a user or pushing the box door by hand, the current rotation speed of the box door changes relative to the set rotation speed, if the user pushes the box door by hand, the box door rotates to the set angle in advance, and the current angle of the box door is equal to the set angle, the electric control rotating shaft is controlled to stop rotating.
In the technical scheme provided by this embodiment, the rotation speed and the rotation angle of the box door are defined and stored, so that the box door can be automatically opened or closed according to a box door control instruction sent by a user. And the current rotating speed and the current rotating angle in the rotating process of the refrigerator door are obtained and judged so as to better monitor the rotating process of the refrigerator door, so that the refrigerator door rotates to the set angle corresponding to the control instruction, the control of the refrigerator door of the refrigerator is more intelligent, and the operation of a user on the refrigerator door is facilitated.
Further, the refrigerator further includes an induction device, the induction device is connected to the controller, referring to fig. 4, in a second embodiment of the present invention, the refrigerator door control method includes the following steps:
step S10, acquiring a box door control instruction sent by a user, and controlling the electric control rotating shaft to rotate according to a set rotating speed corresponding to the control instruction according to the control instruction so as to enable the box door to rotate to a set angle corresponding to the control instruction;
step S20, acquiring the current rotating speed of the box door, and judging whether the current rotating speed of the box door is matched with the set rotating speed;
step S511, if not, judging whether an induction signal generated by the induction device for inducing the operation of the user is received;
and S512, if yes, controlling the electric control rotating shaft to stop rotating.
In this embodiment, in the rotation process of the box door, when it is determined that the current rotation speed of the box door is not matched with the set rotation speed, it indicates that the rotation speed of the box door is changed due to interference in the rotation process.
It is understood that the disturbance may be a change in the rotational speed of the door caused by inadvertent touching by the user or may be a change in the rotational speed of the door caused by intentional disturbance by the user. The sensing device may be a sensor, such as an infrared sensor, disposed inside the box body or inside the box door for sensing whether an object enters the box body or inside the box door; or the pressure sensor can be arranged on the box door and used for sensing whether an object touches the box door or not.
In an embodiment of the present invention, the opening and closing information of the door is to open the door, and the user may want to close the door instead of opening the door while the door rotates at the set rotation speed to open the door. At this time, the user may touch the door to prevent the door from continuing to rotate at the set rotation speed. When a user touches the box door, the pressure sensor arranged on the box door senses the operation of the user and generates a sensing signal to be sent to the controller. And when the controller receives the induction signal, the electric control rotating shaft is controlled to stop rotating. Further, the user may manually control the door to open or close.
In the technical scheme provided by the invention, when the box door rotates, the set rotating speed of the box door is changed, and the box door is controlled to stop rotating currently by judging whether a sensing signal generated by sensing the operation of a user by a sensing device arranged on the refrigerator is received, so that the control of the box door is more intelligent to deal with different operations of the user.
Further, referring to fig. 5, in a third embodiment of the present invention, the method for controlling the door of the refrigerator includes the following steps:
step S10, acquiring a box door control instruction sent by a user, and controlling the electric control rotating shaft to rotate according to a set rotating speed corresponding to the control instruction according to the control instruction so as to enable the box door to rotate to a set angle corresponding to the control instruction;
step S20, acquiring the current rotating speed of the box door, and judging whether the current rotating speed of the box door is matched with the set rotating speed;
step S30, if not, acquiring the current angle of the box door, and judging whether the current angle of the box door is matched with the set angle;
step S521, if not, judging whether an induction signal generated by the induction device for inducing the operation of the user is received;
step S522, if yes, controlling the electric control rotating shaft to stop rotating;
step S523, determining whether an induction signal generated by the induction device inducing the operation of the user is received within a preset time period;
and step 524, if not, controlling the electric control rotating shaft to rotate at a preset first rotating speed so as to enable the box door to rotate to a set angle.
In this embodiment, in the rotation process of the box door, when it is determined that the current rotation speed of the box door is not matched with the set rotation speed, it indicates that the rotation speed of the box door is changed due to interference in the rotation process. It can be understood that the interference may be that the rotation speed of the box door is changed due to careless touching by the user, or may also be that the rotation speed of the box door is changed due to intentional interference by the user, so as to further determine whether the current angle of the box door matches the set angle.
It should be noted that the sensing device may be a sensor, such as an infrared sensor, disposed inside the box body or inside the box door and used for sensing whether an object enters the box body or inside the box door; or the pressure sensor can be arranged on the box door and used for sensing whether an object touches the box door or not.
In an embodiment of the present invention, the opening and closing information of the door is to open the door, the set angle of the door is 135 °, and during the process that the door rotates at the set rotation speed to open the door, the current angle of the door is 90 °, so that the user can take out or put food into the box. When a user takes food from the box body, the infrared sensor arranged in the box body can sense the operation of the user and generate a sensing signal to be sent to the controller. And when the controller receives the induction signal, the electric control rotating shaft is controlled to stop rotating. At this time, the electric control rotating shaft does not execute the control instruction any more, and a user can manually control the opening or closing of the box door.
In this embodiment, when the electrically controlled rotating shaft stops rotating, whether an induction signal generated by the induction device for inducing the operation of the user is received within a preset time period is continuously judged. It can be understood that when the user takes food from the inside of the box body, the user can finish taking food in a short time, and when the user finishes taking food, the sensing device can not receive the operation of the user any more to generate a sensing signal. The preset duration may be a duration set by a user, or a duration counted by the controller according to the usual operation of the user.
Further, when it is determined that the sensing signal generated by the sensing device sensing the operation of the user is not received within the preset time period, which indicates that the user has finished taking food, the clutch device is controlled to execute the closing action, and the electric control rotating shaft is controlled to rotate at a preset first rotating speed, so that the box door rotates to a set angle. It should be noted that the preset first rotation speed may be set by a user and different from a set rotation speed, or the preset first rotation speed may be the same as the set rotation speed in the control instruction, where the set angle is the set angle in the control instruction, and further control the box door to continue to rotate to the set angle, for example, close the box door.
It should be noted that step S523 and step S524 in this embodiment may be after step S512 in the second embodiment, and are not limited herein.
In the technical scheme provided by the invention, when the set rotating speed and the set angle of the refrigerator door are changed in the rotating process of the refrigerator door, the operation intention of a user can be better known by judging whether a sensing signal generated by sensing the operation of the user by the sensing device is received within the preset time length, so that different control on the refrigerator door can be realized according to the operation of the user, and the control on the refrigerator door of the refrigerator is more humanized and intelligent.
Further, the refrigerator also comprises a clutch device, and the clutch device is connected with the controller.
Referring to fig. 6, in a fourth embodiment of the present invention, a door control method of a refrigerator includes the following steps:
step S11, acquiring a box door control instruction sent by a user, and controlling the clutch device to execute closing action according to the control instruction, so that the electric control rotating shaft rotates according to a set rotating speed corresponding to the control instruction, and the box door is driven to rotate to a set angle corresponding to the control instruction;
step S20, acquiring the current rotating speed of the box door, and judging whether the current rotating speed of the box door is matched with the set rotating speed;
step S30, if not, acquiring the current angle of the box door, and judging whether the current angle of the box door is matched with the set angle;
and step S41, if yes, controlling the clutch device to execute a releasing action so as to stop the rotation of the electric control rotating shaft.
It should be noted that the clutch device includes a motor, an electromagnetic module, an elastic member and a plurality of gears, the gears are engaged and connected, the motor is connected with one of the gears to drive the gears to rotate, the electromagnetic module is disposed adjacent to one of the gears, and the electromagnetic module is connected with the elastic member. When the clutch device receives a control instruction for executing the releasing action, the electromagnetic module is electrified to generate magnetic force to adsorb the adjacent gears, so that one gear is separated, the meshed and connected gears stop rotating, the clutch device finishes the releasing action, and at the moment, the box door is in a locked state and cannot be automatically opened or closed. When the clutch device receives a control instruction for executing closing action, the electromagnetic module is powered off to enable the magnetic field to disappear, the electromagnetic module rebounds the adsorbed gears under the action of the elastic piece, and then the gears are meshed and connected again, so that the gears rotate under the driving of the motor, the clutch device completes the closing action, and at the moment, the box door is in a movable state.
Specifically, when a box door control instruction sent by a user is acquired, the box door needs to be opened or closed at the moment, the clutch device is controlled to execute a closing action according to the control instruction, a plurality of gears of the clutch device are sequentially meshed and connected to realize the operation of the clutch device, and the box door is in a movable state to realize the opening or closing at the moment. And then, the electric control rotating shaft rotates according to the set rotating speed corresponding to the control instruction, so that the box door is driven to rotate to the set angle corresponding to the control instruction.
Further, when the current angle of the box door is judged to be equal to the set angle, which indicates that the box door rotates to the set angle corresponding to the control instruction at the moment, the clutch device is controlled to execute a releasing action, so that the electric control rotating shaft stops rotating. At this time, the gears of the clutch device are disengaged from each other, so that the clutch device cannot be operated, the box door is in a locked state and cannot be automatically opened and closed, and at this time, a user can only manually open or close the box door or wait for a next control instruction sent by the user.
In the technical scheme provided by the embodiment, the door of the refrigerator is opened or closed under the combined action of the clutch device and the electric control rotating shaft, so that the door of the refrigerator is controlled more sensitively and accurately.
In addition, in order to achieve the purpose, the invention further provides a refrigerator.

The door opening and closing information comprises opening or closing of the door; the box door speed information can be a set rotating speed preset by a user and stored in a memory; the door angle information may be a set angle preset by a user and stored in the memory. By acquiring the door opening and closing information, the door speed information and the door angle information in the control command, the electronic control rotating shaft 30 can be controlled to rotate towards a preset door opening direction or a preset door closing direction according to a set rotating speed, so that the door 20 rotates to a set angle.
It should be noted that, in the process that the box door 20 rotates to the set angle according to the set rotation speed, the controller 40 obtains the current rotation speed of the box door in real time, and determines whether the current rotation speed of the box door is matched with the set rotation speed, so as to monitor the rotation speed of the box door. When the current rotating speed of the box door is the same as or basically the same as the set rotating speed, the current rotating speed of the box door is judged to be matched with the set rotating speed.
In a preferred embodiment of the present invention, the set rotation speed of the door includes a first door speed and a second door speed, and the set angle of the door includes a first door angle and a second door angle when the door opening/closing information is to open the door.
It can be understood that, when the control command includes the opening and closing information of the door, the set rotation speed of the door, and the set angle of the door, the control command may specifically be at least one of the following:
opening the door to a first door angle at a first door speed;
opening the door to a second door angle at a first door speed;
opening the door to a first door angle at a second door speed;
opening the door to a second door angle at a second door speed;
closing the door at a first door speed;
closing the door at a second door speed.
For example, the set rotation speed is a first door speed, the electronic control rotating shaft 30 rotates according to the first door speed corresponding to the control instruction, in the door rotating process, a user carelessly touches the door 20 to change the door rotation speed, at this time, it is determined that the current door rotation speed is not matched with the first door speed, the current door rotation angle is further obtained, and it is determined whether the current door rotation angle is matched with the set angle. When the current angle of the box door is the same as or basically the same as the set angle, the current angle of the box door is judged to be matched with the set angle.
Further, when it is determined that the current angle of the door is equal to the set angle, which indicates that the door has rotated to the set angle corresponding to the control command at this time, the controller 40 controls the electric control rotating shaft 30 to stop rotating, so as to facilitate the user to control the refrigerator.
For example, in the rotation process of the box door, the box door is forced to rotate by a certain angle due to the occurrence of intervention actions such as turning the body of a user or pushing the box door by hand, the current rotation speed of the box door changes relative to the set rotation speed, if the user pushes the box door by hand, the box door rotates to the set angle in advance, and the current angle of the box door is equal to the set angle, the electric control rotating shaft is controlled to stop rotating.
In the technical scheme provided by this embodiment, the rotation speed and the rotation angle of the box door are defined and stored, so that the box door can be automatically opened or closed according to a box door control instruction sent by a user. And the current rotating speed and the current rotating angle in the rotating process of the refrigerator door are obtained and judged so as to better monitor the rotating process of the refrigerator door, so that the refrigerator door rotates to the set angle corresponding to the control instruction, the control of the refrigerator door of the refrigerator is more intelligent, and the operation of a user on the refrigerator door 20 is facilitated.
In a second embodiment of the refrigerator provided by the present invention, the refrigerator further comprises a sensing device 60, wherein the sensing device 60 is connected to the controller 40; the door control program of the refrigerator, when executed by the controller 40, implements:
the controller 40 obtains a door control instruction sent by a user, and controls the electric control rotating shaft 30 to rotate according to a set rotating speed corresponding to the control instruction according to the control instruction, so that the door 20 rotates to a set angle corresponding to the control instruction;
the controller 40 acquires the current rotating speed of the box door and judges whether the current rotating speed of the box door is matched with the set rotating speed;
if not, the controller 40 determines whether a sensing signal generated by the sensing device 60 sensing the operation of the user is received;
if yes, the controller 40 controls the electrically controlled rotating shaft 30 to stop rotating.
In this embodiment, in the rotation process of the box door 20, when it is determined that the current rotation speed of the box door is not matched with the set rotation speed, it indicates that the rotation speed of the box door 20 is changed due to interference in the rotation process.
It is understood that the disturbance may be a change in the rotational speed of the door caused by inadvertent touching by the user or may be a change in the rotational speed of the door caused by intentional disturbance by the user. The sensing device may be a sensor, such as an infrared sensor, disposed inside the box body or inside the box door for sensing whether an object enters the box body or inside the box door; or the pressure sensor can be arranged on the box door and used for sensing whether an object touches the box door or not.
In an embodiment of the present invention, the opening/closing information of the door is to open the door, and the user may want to close the door instead of opening the door when the door 20 rotates at the set rotation speed to open the door. The user may touch the door 20 to prevent the door from continuing to rotate at the set speed. When the user touches the door 20, the pressure sensor disposed on the door 20 senses the user's operation and generates a sensing signal to be transmitted to the controller 40. When the controller 40 receives the sensing signal, the electronic control rotating shaft 30 is controlled to stop rotating. Further, the user may manually control the door 20 to be opened or closed.
In the technical scheme provided by the invention, when the box door rotates, the set rotating speed of the box door is changed, and the box door is controlled to stop rotating currently by judging whether a sensing signal generated by sensing the operation of a user by a sensing device arranged on the refrigerator is received, so that the control of the box door is more intelligent to deal with different operations of the user.
In a third embodiment of the refrigerator provided by the present invention, the door control program of the refrigerator, when executed by the controller 40, implements:
the controller 40 obtains a door control instruction sent by a user, and controls the electric control rotating shaft 30 to rotate according to a set rotating speed corresponding to the control instruction according to the control instruction, so that the door 20 rotates to a set angle corresponding to the control instruction;
the controller 40 acquires the current rotating speed of the box door and judges whether the current rotating speed of the box door is matched with the set rotating speed;
if not, the controller 40 acquires the current angle of the box door and judges whether the current angle of the box door is matched with the set angle;
if not, the controller 40 determines whether a sensing signal generated by the sensing device 60 sensing the operation of the user is received;
if yes, the controller 40 controls the electric control rotating shaft 30 to stop rotating;
the controller 40 determines whether an induction signal generated by the induction device inducing the operation of the user is received within a preset time period;
if not, the controller 40 controls the electric control rotating shaft 30 to rotate at a preset first rotating speed, so that the box door 20 rotates to a set angle.
In this embodiment, in the rotation process of the box door 20, when it is determined that the current rotation speed of the box door is not matched with the set rotation speed, it indicates that the rotation speed of the box door 20 is changed due to interference in the rotation process. It is understood that the interference may be that the user inadvertently touches the door to change the rotation speed of the door, or may also be that the user intentionally interferes the door to change the rotation speed of the door, so as to further determine whether the current angle of the door is equal to the set angle.
The sensing device 60 may be a sensor disposed inside the box 10 or inside the door 20 for sensing whether an object enters the box 10 or inside the door 20, such as an infrared sensor; or may be a pressure sensor provided on the door 20 to sense whether an object touches the door.
In an embodiment of the present invention, the opening and closing information of the door is to open the door, the set angle of the door is 135 °, and during the process that the door 20 rotates at the set rotation speed to open the door 20, the current angle of the door is 90 °, so that the user can take out or put food into the box. When a user takes food from the cabinet 10, the infrared sensor provided in the cabinet 10 senses the user's operation and generates a sensing signal to be transmitted to the controller 40. When the controller 40 receives the sensing signal, the electronic control rotating shaft 30 is controlled to stop rotating. At this time, the electrically controlled spindle 30 no longer executes the control command, and the user can manually control the opening or closing of the door 20.
In this embodiment, when the electric control shaft 30 stops rotating, it is determined whether a sensing signal generated by the sensing device 60 sensing the operation of the user is received within a preset time period. It can be understood that when the user takes food from the inside of the housing 10, the user can take food in a short time, and when the user takes food, the sensing device 60 does not receive the operation of the user and generates a sensing signal. The preset duration may be a duration set by a user, or a duration counted by the controller according to the usual operation of the user.
Further, when the controller 40 determines that the sensing signal generated by the sensing device 60 sensing the operation of the user is not received within the preset time period, which indicates that the user has finished taking food, the controller 40 controls the clutch device 70 to perform the closing action and controls the electrically controlled rotating shaft 30 to rotate at the preset first rotating speed, so that the box door 20 rotates to the set angle. It should be noted that the preset first rotation speed may be set by a user and different from the set rotation speed, or the preset first rotation speed may be the same as the set rotation speed in the control command, where the set angle is the set angle in the control command, and further control the box door 20 to continue to rotate to the set angle, for example, close the box door 20.
In the technical scheme provided by the invention, when the set rotating speed and the set angle of the refrigerator door are changed in the rotating process of the refrigerator door 20, the operation intention of a user can be better known by judging whether a sensing signal generated by sensing the operation of the user by the sensing device 60 is received within the preset time, so that different controls on the refrigerator door 20 are realized according to the operation of the user, and the control on the refrigerator door 20 of the refrigerator is more humanized and intelligent.
In a fourth embodiment of the refrigerator provided by the present invention, the refrigerator further comprises a clutch device 70, wherein the clutch device 70 is connected with the controller; the door control program of the refrigerator, when executed by the controller 40, implements:

the controller 40 acquires the current rotating speed of the box door and judges whether the current rotating speed of the box door is matched with the set rotating speed;
if not, the controller 40 acquires the current angle of the box door and judges whether the current angle of the box door is matched with the set angle;
if yes, the controller 40 controls the clutch device 70 to perform a releasing action, so as to stop the rotation of the electrically controlled rotating shaft 30.
It should be noted that the clutch device 70 includes a motor, an electromagnetic module, an elastic member, and a plurality of gears, where the plurality of gears are engaged and connected, the motor is connected to one of the gears to drive the plurality of gears to rotate, the electromagnetic module is disposed adjacent to one of the plurality of gears, and the electromagnetic module is connected to the elastic member. When the clutch device 70 receives a control command for executing a releasing action, the electromagnetic module is energized to generate magnetic force to adsorb the adjacent gears, so that one of the gears is disengaged, the gears in meshed connection stop rotating, the clutch device 70 completes the releasing action, and at this time, the box door 20 is in a locked state and cannot be automatically opened or closed. When the clutch device 70 receives a control instruction for executing the closing action, the electromagnetic module is powered off to make the magnetic field disappear, the electromagnetic module rebounds the adsorbed gears under the action of the elastic member, so that the gears are meshed and connected again, the gears are driven by the motor to rotate, the clutch device 70 completes the closing action, and at the moment, the box door 20 is in a movable state.
Specifically, when the controller 40 obtains a door control instruction sent by a user, at this time, the door 20 needs to be opened or closed, the controller 40 controls the clutch device 70 to perform a closing action according to the control instruction, then the plurality of gears of the clutch device 70 are sequentially engaged and connected to realize the operation of the clutch device 70, and at this time, the door 20 is in a movable state to realize the opening or closing. Further, the electrically controlled rotating shaft 30 rotates at a set rotating speed corresponding to the control command, so as to drive the door 20 to rotate to a set angle corresponding to the control command.
Further, when it is determined that the current angle of the door is equal to the set angle, which indicates that the door 20 has rotated to the set angle corresponding to the control command at this time, the clutch device 70 is controlled to perform a releasing action, so that the electrically controlled spindle 30 stops rotating. At this time, the gears of the clutch device 70 are disengaged from each other, so that the clutch device 70 cannot be operated, the box door 20 is in a locked state and cannot be opened or closed automatically, and at this time, the user can only manually open or close the box door 20, or wait for the next control command sent by the user.
In the technical solution provided in this embodiment, the door 20 is opened or closed by the combined action of the clutch device 70 and the electrically controlled rotating shaft 30, so that the door of the refrigerator is controlled more sensitively and accurately.
