Example one
The embodiment provides a control method for automatically opening and closing a door, which can be used for controlling the rotation of a rotating door of an intelligent household appliance, such as the rotation of a door body of an intelligent refrigerator and the rotation of a door body of an intelligent drum washing machine, and can also be used for controlling the rotation or horizontal movement of the automatically opening and closing door on a building, so that a user can conveniently interfere with the motion of the automatically opening and closing door in real time.
Specifically, referring to fig. 1, in this embodiment, the method for controlling the automatic opening and closing of the door includes the following steps:
s1, detecting whether the automatic door is under the action of external force, if so, executing the step S2; if not, step S4 is executed.
In the step, if the user wants to manually intervene in the execution process of automatically opening and closing the door, the user needs to apply external force to the automatically opening and closing the door, and whether the user wants to manually intervene in the execution process of automatically opening and closing the door is judged by detecting whether the automatically opening and closing the door is acted by the external force; if the automatic door opening and closing action is detected to be subjected to the external force, which indicates that the user wants to manually intervene in the movement of the automatic door opening and closing, the step S2 is executed; if it is detected that the automatic opening and closing door is not subjected to the external force, which indicates that no human intervention exists at this time, step S4 is executed.
S2, judging whether the external force has the trend of changing the current state of the automatic opening and closing door, if yes, executing the step S3; if not, step S4 is performed.
And S3, controlling the automatic opening and closing door to change the current state.
When it is detected in step S1 that the automatic opening and closing door is acted by external force, and the determination result in step S2 is that the external force has a tendency to change the current state of the automatic opening and closing door, which indicates that the user wants to intervene in the motion process of the automatic opening and closing door, the result of the intervention may be that: the automatic opening and closing door is changed from a moving state to a static state, and the automatic opening and closing door is changed from the static state to the moving state or is automatically moved in the opposite direction.
And S4, controlling the automatic opening and closing door to keep the current state.
When step S1 detects that the automatic opening and closing door is not subjected to the external force, which indicates that the user does not intend to interfere with the movement of the automatic opening and closing door at this time, the automatic opening and closing door continues to maintain the current state, i.e. continues to maintain the movement or continues to maintain the still state. When it is detected in step S1 that the automatic opening and closing door is subjected to the external force, the determination result in step S2 is that the external force does not change the trend of the current state of the automatic opening and closing door, which indicates that the user does not interfere with the movement of the automatic opening and closing door at this time, and the automatic opening and closing door continues to maintain the current state.
The control method for automatically opening and closing the door provided by the embodiment can facilitate a user to interfere the motion of the automatically opening and closing door in real time, and particularly, when the user wants to interfere the motion of the automatically opening and closing door, the user does not need to wait for the automatically opening and closing door to be automatically opened or closed, and only needs to apply an external force to the automatically opening and closing door in the motion of the automatically opening and closing door, so that the automatically opening and closing door can make a corresponding response according to the action of the external force.
Example two
The embodiment provides a control method for automatically opening and closing a door, which can be used for controlling the rotation of a rotating door of an intelligent household appliance, such as the rotation of a door body of an intelligent refrigerator and the rotation of a door body of an intelligent drum washing machine, and can also be used for controlling the rotation or horizontal movement of the automatically opened and closed door on a building, so that a user can conveniently interfere with the motion of automatically opening and closing the door in real time.
Specifically, referring to fig. 2, in this embodiment, the method for controlling the automatic opening and closing of the door includes the following steps:
s1, detecting whether the automatic door is under the action of external force, if so, executing the step S2; if not, step S4 is performed.
In the step, if the user wants to manually intervene in the execution process of automatically opening and closing the door, the user needs to apply external force to the automatically opening and closing the door, and whether the user wants to manually intervene in the execution process of automatically opening and closing the door is judged by detecting whether the automatically opening and closing the door is acted by the external force; if the automatic door opening and closing action is detected to be subjected to the external force, which indicates that the user wants to manually intervene in the movement of the automatic door opening and closing, the step S2 is executed; if it is detected that the automatic opening and closing door is not subjected to the external force, which indicates that no human intervention exists at this time, step S4 is executed.
S2, judging whether the external force has the trend of changing the current state of the automatic opening and closing door, if yes, executing the step S3; if not, step S4 is performed.
It has been detected in step S1 that the automatic opening and closing door is subjected to the external force. Even if the automatically opening and closing door is subjected to an external force, the external force may change the current state of the automatically opening and closing door, and may not change the current state of the automatically opening and closing door. It is therefore necessary to determine whether the external force has a tendency to change the current state of the automatically opening and closing door.
Taking a rotary automatic door opening and closing as an example, the current state in this step is that the automatic door opening and closing is in an automatic rotating process or the automatic door opening and closing is in a static state. Taking a movable automatic door opening and closing as an example, the current state in this step is that the automatic door opening and closing is in the automatic moving process along the first direction or the automatic door opening and closing is in a static state. Taking a rotary automatic door opening and closing as an example, the trend of changing the current state of the automatic door opening and closing in the step refers to: under the action of the external force, the rotation direction of the automatic opening and closing door changes; or the automatic opening and closing door is changed from a static state to a rotating state; or the automatic opening and closing door is changed from a rotating state to a static state. For example, when the automatic opening and closing door rotates, the external force enables the automatic opening and closing door to rotate reversely, and the external force is judged to have a trend of changing the current state of the automatic opening and closing door; when the automatic door opening and closing device is static, the external force enables the automatic door opening and closing device to rotate, and the external force is judged to have the trend of changing the current state of the automatic door opening and closing device; when the automatic door opening and closing mechanism rotates, the external force stops the automatic door opening and closing mechanism from rotating, and the external force is judged to have a tendency of changing the current state of the automatic door opening and closing mechanism; when the automatic opening and closing door rotates, the external force enables the automatic opening and closing door to rotate in the same direction in an accelerated mode, and then the fact that the external force does not change the trend of the current state of the automatic opening and closing door is judged.
Under the action of external force, whether the automatic opening and closing door rotates or not is taken as a standard to judge whether the external force has a trend of changing the current state of the automatic opening and closing door. Specifically, step S2 includes the steps of:
s21, judging whether the current state of the automatic opening and closing door is a motion state, if so, executing a step S22; if not, step S24 is performed.
In this step, the current state of the automatically opened and closed door may be that the automatically opened and closed door is in a rotating process or that the automatically opened and closed door is in a static state. Therefore, it is necessary to determine whether the current state of the automatic opening and closing door is a motion state.
S22, judging whether the automatic door opening and closing device stops rotating under the action of external force, if so, judging that the external force has the trend of changing the current state of the automatic door opening and closing device, and executing a step S3; if not, go to step S23;
s23, judging whether the rotation direction of the automatic opening and closing door changes under the action of external force, if yes, judging that the external force has the tendency of changing the current state of the automatic opening and closing door, and executing a step S3; if not, determining that the external force does not change the trend of the current state of the automatic opening and closing door, and executing step S4;
s24, judging whether the automatic door opening and closing device rotates under the action of external force, if so, judging that the external force has the trend of changing the current state of the automatic door opening and closing device, and executing a step S3; if not, it is determined that the external force does not tend to change the current state of the automatically opening and closing door, and step S4 is performed.
And S3, controlling the automatic opening and closing door to change the current state.
When it is detected in step S1 that the automatic door opening and closing device is subjected to an external force, and the determination result in step S2 is that the external force has a tendency to change the current state of the automatic door opening and closing device, which indicates that the user wants to intervene in the movement process of the automatic door opening and closing device, the intervention result may be such that: the automatic opening and closing door is changed from a moving state to a static state, and the automatic opening and closing door is changed from the static state to the moving state or is automatically moved in the opposite direction.
And S4, controlling the automatic opening and closing door to keep the current state.
When step S1 detects that the automatic door closer or closer is not subjected to the external force, which indicates that the user does not intend to interfere with the movement of the automatic door closer or closer, the automatic door closer or closer continues to keep the current state, i.e. continues to keep moving or continues to keep still. When it is detected in step S1 that the automatic opening and closing door is subjected to the external force, the determination result in step S2 is that the external force does not change the trend of the current state of the automatic opening and closing door, which indicates that the user does not interfere with the movement of the automatic opening and closing door at this time, and the automatic opening and closing door continues to maintain the current state.
The control method for automatically opening and closing the door provided by the embodiment can facilitate a user to interfere the motion of the automatically opening and closing door in real time, and particularly, when the user wants to interfere the motion of the automatically opening and closing door, the user does not need to wait for the automatically opening and closing door to be automatically opened or closed, and only needs to apply an external force to the automatically opening and closing door in the motion of the automatically opening and closing door, so that the automatically opening and closing door can make a corresponding response according to the action of the external force.
EXAMPLE III
The embodiment provides a control method for automatically opening and closing a door, which can realize manual intervention of a user on the automatically opening and closing door in the automatic rotation process of the automatically opening and closing door.
Specifically, the control method for automatically opening and closing the door of the embodiment is suitable for the rotation of the refrigerator door on the refrigerator or the rotation of the door body of the drum washing machine.
Referring to fig. 3, the control method of the control method for automatically opening and closing the door includes the steps of:
s1, detecting whether the automatic door is under the action of external force, if so, executing the step S2; if not, step S4 is performed.
S2, judging whether the external force has the trend of changing the current state of the automatic opening and closing door, if yes, executing the step S3; if not, step S4 is performed.
Alternatively, step S2 in this embodiment is the same as step S2 in the second embodiment. In the step, the automatic door opening and closing state is in a rotating state, and if the automatic door opening and closing state is reversely rotated or is static under the action of external force, the external force is judged to have the tendency of changing the current state of the automatic door opening and closing state.
And S3, controlling the automatic opening and closing door to change the current state.
Specifically, in step S3, the automatic opening/closing door is controlled to automatically rotate in the direction of the action of the external force or to stop rotating.
In this step, if the user wants to intervene in the movement of the automatically opening and closing door, the user may want the automatically opening and closing door to rotate reversely or stop rotating. In order to accurately judge the interference intention of the user, in the present embodiment, the step S3 includes the following steps:
s31, judging whether the angle change of the automatic opening and closing door under the action of external force exceeds a first preset value within a first preset time value, if so, executing a step S32; if not, step S33 is performed.
In the step, the interference intention of the user is accurately judged by setting a first preset time value and a first preset value. In the actual rotation process of the automatic opening and closing door, if a user wants to manually block the automatic opening and closing door to stop rotating or reversely rotate, after the user blocks the automatic opening and closing door in front of the automatic opening and closing door, the automatic opening and closing door can rotate within a certain angle range under the action of inertia. In order to prevent misjudgment caused by rotation of the automatic door opening and closing within a certain angle range under the action of inertia, a first preset time value is set in the step, and whether the angle change of the automatic door opening and closing under the action of external force within the first preset time value exceeds a first preset value or not is judged to accurately judge the interference intention of a user. The first preset value is an absolute value.
If the user wants to stop rotating the automatically opened and closed door in the automatic rotation process, the user applies external force to the automatically opened and closed door, the external force acts on the automatically opened and closed door to stop the automatically opened and closed door from continuously rotating, the angle change of the automatically opened and closed door under the action of the external force in the first preset time value does not exceed the first preset value, the user is judged that the user wants to stop rotating the automatically opened and closed door, and the step S33 is executed.
If the user wants to make the automatic opening and closing door in the automatic rotation process rotate reversely, the user can apply external force to the automatic opening and closing door, and the external force acts on driving the automatic opening and closing door to rotate reversely. When the automatic opening and closing door reversely rotates within the first preset time value by the external force exceeding the first preset value, it is determined that the user desires the automatic opening and closing door to reversely rotate, and step S32 is performed.
In this step, the smaller the first preset time value is, the higher the response sensitivity of the automatic opening and closing door to external force is. The magnitude of the first predetermined time value is designed by the designer at his or her discretion without undue limitation.
The smaller the first preset value is, the higher the response sensitivity of the automatic opening and closing door to external force is. The first preset value can be set by a designer according to needs, and is not limited too much.
And S32, controlling the automatic opening and closing door to stop rotating, and automatically rotating along the action direction of the external force after the rotation is stopped.
Step S31 detects that the rotation angle of the automatic opening and closing door under the action of the external force exceeds the first preset value within the first preset time value, determines that the user intends to interfere with the automatic opening and closing door to rotate in the opposite direction, controls the automatic opening and closing door to stop rotating first, and automatically rotates along the action direction of the external force after stopping rotating.
In this step, control automatic switch door is after stall, the automatic effect direction of external force that follows rotates, can convenience of customers intervene the motion of automatic switch door in real time, and when the user wants to intervene the motion of automatic switch door, need not to wait for, only need apply an external force to the automatic switch door, the automatic switch door just can rotate according to the effect direction automation of external force, need not user's continuation and apply external force to the automatic switch door, only need the user provide external force temporarily can, it is intelligent and automatic competent, user experience can be improved.
The automatic door opening and closing device is controlled to stop rotating firstly and then automatically rotate according to the direction of an external force, so that the impact of the automatic door opening and closing device suddenly changing the rotating direction on the driving motor and the transmission mechanism can be avoided.
And S33, controlling the automatic opening and closing door to stop rotating.
Step S31 detects that the rotation angle of the automatically opened and closed door under the action of the external force does not exceed the first preset value, determines that the user intends to stop the automatically opened and closed door rotating automatically, and controls the automatically opened and closed door to stop rotating.
And S4, controlling the automatic opening and closing door to keep the current state.
When step S1 detects that the automatic opening and closing door is not subjected to the external force, which indicates that the user does not intend to interfere with the movement of the automatic opening and closing door at this time, the automatic opening and closing door continues to maintain the current state, i.e. continues to maintain the movement or continues to maintain the still state. When it is detected in step S1 that the automatic opening and closing door is subjected to the external force, the determination result in step S2 is that the external force does not change the trend of the current state of the automatic opening and closing door, which indicates that the user does not interfere with the movement of the automatic opening and closing door at this time, and the automatic opening and closing door continues to maintain the current state.
The following description is made in terms of the case where a user interferes with the refrigerator door during rotation of the refrigerator door:
in the automatic rotation process of the refrigerator door, whether the refrigerator door is under the action of an external force is detected; if the refrigerator door is detected not to be affected by the external force, the situation that the user unintentionally interferes with the automatic movement of the refrigerator door is indicated; if the refrigerator door is detected to be acted by external force, whether the external force has the trend of changing the current state of the automatic opening and closing door is further judged so as to further judge the interference intention of a user.
