Description
Automatic door opening control method, device and household appliance
[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on December 28, 2023, with application number 202311832958.2 and invention name “Automatic door opening control method, device and household appliance”, the entire contents of which are incorporated by reference in this disclosure. Technical Field
[0002] The present disclosure relates to the field of home appliance technology, and in particular to an automatic door opening control method, device, and home appliance. Background Art
[0003] To improve the convenience of home appliances such as washing machines, related technologies have proposed installing automatic door opening devices in these appliances. After the appliance completes its primary function, the automatic door opening device controls the device, which applies force to the door, automatically opening it. If the user wishes to actively control the door opening, they can also initiate an opening command by pressing a control button.
[0004] In a specific implementation, the automatic door opening device includes a drive motor, a transmission mechanism, a door opening actuator, and a position detection component. The position detection component determines that the door opening actuator has moved to a specific state by detecting the position of a specific transmission component in the transmission mechanism. Subsequently, after the drive motor is controlled to rotate for a specific period of time, the door body can be opened and the door opening actuator can be reset. However, the control strategy for controlling the movement of the door opening actuator does not have negative feedback. Under heavy load conditions, although the motor is controlled to rotate for a set period of time, it cannot ensure that the door body has automatically opened and the specific transmission component has been correctly reset.

[0043] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein.

[0045] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".
[0046] In order to solve the problem that the existing door opening control of the automatic door opening device, after the position detection component detects that the specific transmission component in the transmission mechanism has moved to the target position, the drive motor is operated for a set period of time and then powered off, which may not cause the door to open automatically or the specific transmission component is not correctly returned to its position, the embodiment of the present disclosure provides a new automatic door opening control method.
[0047] In order to more clearly understand the automatic door opening control method provided by the embodiment of the present disclosure, the following first briefly introduces the automatic door opening device.
[0048] As generally described in the background art, the automatic door opening device includes a drive motor, a transmission mechanism, a door opening actuator and a position detection component. In addition, the automatic door opening device is also provided with a rebound elastic member.
[0049] The drive motor is used to generate power to drive the door opening actuator.
[0050] The transmission mechanism is used to convert the rotational motion of the drive motor into other types of motion and amplify the torque generated by the drive motor during rotation, thereby enabling the door opening actuator to be driven by a relatively low-power drive motor. In some embodiments, the transmission mechanism may employ a gear transmission mechanism to convert the rotational force generated by the drive motor into a higher-torque rotational force through multiple gear transmission pairs. In other embodiments, the transmission mechanism may employ a mechanism such as a slider crank mechanism or a crank rocker mechanism that can convert rotational motion into translational motion or swinging motion.
[0051] In the embodiment of the present disclosure, an intermediate transmission member is provided in the transmission mechanism, and the intermediate transmission member can be a translation member, a swing member, or a rotation member. In practical applications, considering that the transmission mechanism should save as much space as possible, the aforementioned intermediate transmission member is preferably provided as a translation member.
[0052] The door opening actuator is a mechanism for applying power to the door body, thereby achieving the door body opening. In some embodiments, the door opening actuator can be a cam mechanism, which applies a force to the door latch through the rotation of the cam, and uses the door latch to drive the door body to achieve automatic opening of the door body.
[0053] The position detection component is used to detect the position of the intermediate transmission component of the aforementioned transmission mechanism, and determine the action state of the door opening actuator through the position of the intermediate transmission component, and then determine whether the automatic door opening device has correctly performed the door opening operation.
[0054] In a specific implementation, the position detection component can be a Hall sensor, a distance detection sensor, or a mechanical switch, preferably a two-state detection component such as a Hall switch or a mechanical switch. It should be noted that when the distance detection sensor is a Hall switch, a metal component or a magnetic component should be present at a specific position in the intermediate transmission member.
[0055] The rebound elastic member is used to enable the intermediate transmission member and the subsequent transmission mechanism and door opening actuator to reset when the driving force generated by the drive motor cannot be applied to the intermediate transmission member.
[0056] The following is an analysis of the automatic door opening control method provided by the embodiment of the present disclosure. Figure 1 is a flow chart of the automatic door opening control method provided by the embodiment of the present disclosure. As shown in Figure 1, the automatic door opening control method provided by the embodiment of the present disclosure includes S110-S120.
[0057] It should be noted that the automatic door opening control method provided in the embodiment of the present disclosure is controlled and executed by a controller in a device on which an automatic door opening device is installed. The aforementioned device on which an automatic door opening device is installed can be various types of household appliances, such as clothing processing equipment such as washing machines and dryers, and can also be equipment such as microwave ovens and electric ovens.
[0058] S110: Determine whether a door opening trigger instruction is received, control the drive motor to rotate, and control the position detection component to detect the position of the intermediate transmission component.
[0059] The door opening trigger command is a command used to control the automatic door opening device to execute the door opening action. In some embodiments, the door opening trigger command can be generated by a user through operation of the device equipped with the automatic door opening device, or it can be automatically generated by the controller of the device equipped with the automatic door opening device after determining that the device has completed a specific program operation.
[0060] As previously analyzed, the automatic door opening device generates the power to open the door by rotating the drive motor. Accordingly, the received door opening trigger command is the command used to control the rotation of the drive motor. In the disclosed embodiment, upon receiving the door opening trigger command, the controller controls the closure of a switch connected in series with the drive motor, thereby conducting current in the circuit containing the drive motor and thereby controlling the rotation of the drive motor.
[0061] In the embodiment of the present disclosure, while controlling the rotation of the drive motor, the controller controls the position detection component to detect the position of the intermediate transmission member. Specifically, the controller can control the position detection component to be powered on, thereby enabling the position sensor to detect the position of the intermediate transmission member.
[0062] When the structure of the automatic door opening device is normal, after the drive motor is powered on and rotated, the drive motor will drive the door opening actuator to operate through the transmission mechanism. While the transmission mechanism is operating, the intermediate transmission member in the transmission mechanism will move from the initial position to the target position. The target position is a position that indicates that the door opening actuator has achieved door opening, or indicates that the door opening actuator can achieve door opening during the back movement. In some embodiments, when the door opening actuator reaches the target position, or after reaching the target position and staying for a period of time, it indicates that the door opening actuator is open. It should be noted that the target position referred to in the embodiment of the present disclosure can be a position point or a position interval.
[0063] In the disclosed embodiment, after the intermediate transmission member reaches the target position, or after a period of time at the target position, the power generated by the drive motor cannot be applied to the intermediate transmission member due to changes in the connection between the transmission components. Consequently, the power cannot be transmitted to the door opening actuator through the intermediate transmission member. Subsequently, the elastic force generated by the compression of the rebound elastic member is applied to the intermediate transmission member, causing the intermediate transmission member to return and move out of the target position.
[0064] S120: Determine that the intermediate transmission member moves from the initial position to the target position and then leaves the target position, and control the drive motor to stop rotating.
[0065] As previously analyzed, the target position indicates that the door opening actuator has opened the door, or that the actuator is ready to open the door during its return movement. In other words, if the intermediate transmission member moves from its initial position to the target position and then leaves the target position, the door opening actuator can be determined to have opened the door, and the drive motor can be stopped.
[0066] With the automatic door opening control method provided by the embodiment of the present disclosure, after receiving the door opening trigger command and controlling the drive motor to rotate, the controller controls the drive motor to stop rotating only after the intermediate transmission member moves to the target position and then leaves the target position. Because the target position indicates that the door opening actuator has achieved door opening, or indicates that the door opening actuator can achieve door opening during the return movement process, once it is determined that the intermediate transmission member has left the target position, it is determined that the door has been opened by the door opening actuator, and the drive motor can be controlled to stop rotating.
[0067] In the related art, when it is determined that the intermediate transmission member has moved to the target position, the motor is controlled to stop, or when it is determined that the intermediate transmission member has moved to the target position and a certain period of time has passed, the drive motor is controlled to stop again. This may cause the intermediate transmission member to get stuck in a non-initial position, and although the door opening has not been completed, the controller mistakenly believes that the door opening has been completed. With the solution of the embodiment of the present disclosure, after detecting that the intermediate transmission member has moved to the target position, it is further detected whether the intermediate transmission member has left the target position. Only after the intermediate transmission member has left the target position will it be determined that the door opening has been completed, ensuring that the automatic door opening device has completed a complete door opening action, avoiding the problem of mistakenly believing that the door opening has been completed even though the door opening action has not been completed, and improving the reliability of the automatic door opening.
[0068] As previously mentioned, the position detection component in some embodiments of the present disclosure may be a real-time position detection component, such as a distance detection sensor. In this case, the controller may determine the real-time position of the intermediate detection component based on the distance signal generated by the distance detection sensor, and further determine whether the intermediate transmission member has moved to the target position or has moved away from the target position.
[0069] In other embodiments, the position detection component in the embodiment of the present disclosure may also be a two-state detection component such as a Hall switch. In this case, the position detection component detects the position of the intermediate position transmission member, determines that the intermediate transmission member moves from the initial position to the target position, and then leaves the target position, which may include the following steps S121-S122.
[0070] S121: In response to the detection state of the position detection component being switched from the first state to the second state, determining that the intermediate transmission member moves from the initial position to the target position.
[0071] In the embodiments of the present disclosure, the first state is the output state of the position detection component when it is not triggered by the intermediate transmission member, and the second state is the output state of the position detection component when it is triggered by the intermediate transmission member. For example, in some embodiments, the first state may be a state of outputting a low level, and the second state may be a state of outputting a high level.
[0072] If the position detection component switches from the first state to the second state, it is determined that the position detection component has switched from a state in which it is not triggered by the intermediate transmission member to a state in which it is detected and triggered by the intermediate transmission member, i.e., the intermediate transmission member has moved to a position close to or even abutting the position detection component. Since the aforementioned position is pre-set as the target position, it can be determined that the intermediate transmission member has moved from its initial position to the target position.
[0073] S122 : In response to the position detection component switching back from the second state to the first state, determining that the intermediate transmission member leaves the target position.
[0074] If the detection state of the position detection component switches from the second state to the first state, it is determined that the position detection component switches from the state of being triggered by the intermediate component to the state of no longer being triggered by the intermediate transmission detection, and at this time it is determined that the intermediate transmission component has left the target position.
[0075] FIG2 is a flow chart of an automatic door opening control method provided by another embodiment of the present disclosure. As shown in FIG2 , the automatic door opening control method provided by other embodiments includes S210 - S250.
[0076] S210: Determine whether a door opening trigger command is received and detect whether the door lock is in an unlocked state; if not, execute S220; if so, execute S240.
[0077] S220: Control the door lock to perform the unlocking operation and detect whether the door lock is in an action state; if so, continue to execute S220; if not, execute S230.
[0078] S230: Detect whether the door lock has been switched to the unlocked state; if so, execute S240; if not, execute S220.
[0079] S240: Control the driving motor to rotate, and control the position detection component to detect the position of the intermediate transmission member.
[0080] S250: Determine that the intermediate transmission member moves from the initial position to the target position and then leaves the target position, and control the drive motor to stop rotating.
[0081] In practice, to ensure safety during operation, household appliances are equipped with locks that lock the door during operation to prevent it from being opened due to excessive force. For example, a drum washing machine locks its door during operation to prevent it from being opened due to internal push or external pull.
[0082] In order to avoid the conflict between the working state of the automatic door opening device and the locked state of the door lock during the door opening operation, after receiving the door opening trigger instruction, the embodiment of the present disclosure first detects whether the door lock is in the unlocked state.
[0083] If the door lock is in the unlocked state, the automatic door opening device can be controlled to perform the door opening action, that is, the drive motor can be controlled to rotate, and the position detection component can be controlled to detect the position of the intermediate transmission member.
[0084] If the door lock is not in the unlocked state, then the door lock may be in two states: (1) the door lock is in the locked state; (2) the door lock is in the action state, which may be the action state from locked to unlocked, or the action state from unlocked to locked.
[0085] In the embodiment of the present disclosure, when it is determined that the door lock is not in the unlocked state, the door lock is controlled to perform the unlocking operation, that is, the door lock is controlled to perform the action of switching from the locked state to the unlocked state. At this time, it is possible to detect whether the door lock is in the action state. If the door lock is in the action state, it is impossible to determine whether the door lock is successfully unlocked, so it is still necessary to detect whether it is in the action state. If the door lock completes the unlocking action, in order to avoid the problem of unlocking errors or unsuccessful unlocking, it is necessary to determine again whether the lower door lock is successfully unlocked, that is, to determine whether the door lock has been successfully unlocked. Therefore, it is possible to control the drive motor to rotate, and control the position moving component to detect the position of the intermediate transmission component to determine whether the automatic door opening operation is correctly performed.
[0086] The specific implementation method of S240-S250 in the embodiment of the present disclosure is the same as that in the previous embodiment and will not be repeated here. Please refer to the previous analysis for details.
[0087] As previously analyzed, door locks are designed to ensure the safety of home appliances during use, locking the door when it determines that the appliance is in operation. In practice, if, after receiving a door-open trigger command and detecting that the door lock is not already unlocked, the door lock is controlled to unlock, a safety hazard may occur. To avoid this issue, in some embodiments, before executing S220, the controller also executes S250.
[0088] S250: Determine whether the current state of the home appliance meets the unlocking condition; if so, execute S220.
[0089] The aforementioned household appliance is a component equipped with a lock and an automatic door opening device. Whether the current state of the household appliance satisfies the unlocking condition needs to be determined based on the state of the operation being performed by the household appliance.
[0090] In some embodiments, the home appliance is a similar clothing processing device such as a washing machine, a dryer, a washer-dryer, etc. The aforementioned determination of whether the current state of the home appliance satisfies the unlocking condition may vary accordingly.
[0091] For example, if the household appliance is a washing machine, if it is determined that the water level of the laundry processing device is higher than the set water level, or the laundry processing device is in a rotating state, it is determined that the current state of the laundry processing device does not meet the unlocking condition.
[0092] For another example, if the home appliance is a clothes dryer, if it is determined that the clothes processing temperature in the clothes dryer is within a safe temperature range, it is determined that the current state does not meet the unlocking condition.
[0093] In some other embodiments, the household appliance is a microwave oven. If it is determined that the microwave oven is in a microwave heating state, it is determined that the current state does not meet the unlocking condition.
[0094] It should be noted that if the determination of whether the current state of the home appliance meets the unlocking conditions includes multiple determination conditions, the unlocking operation cannot be performed if any one of the determination conditions does not meet the unlocking conditions. Conversely, the unlocking operation can only be performed if all the unlocking conditions are met.
[0095] In actual applications, if the current state of the subject device does not meet the unlocking conditions, in order to avoid the user thinking that the device is faulty, a corresponding prompt message can be generated to remind the user what operation needs to be performed, or what state the home appliance needs to enter before the unlocking and door opening operation can be performed.
[0096] In some embodiments, although the current state of the home appliance meets the unlocking condition, in order to prevent various problems caused by children opening the door and triggering it to open, the subject device may enable the child lock function. In this case, before executing the aforementioned S220, the controller also needs to execute the following S260.
[0097] S260: Detect whether the child lock function of the clothing processing device is turned on; if not, execute S220.
[0098] If the child lock function of the laundry processing device is enabled, the lock is in the locked state and cannot be used to control the laundry processing device to perform an unlocking operation. In this case, a corresponding prompt message can be generated to remind the user that the child lock function is currently enabled and that the unlocking operation and door opening operation can only be performed after the child lock is disabled.
[0099] In some embodiments, the door opening trigger instruction may be generated by a user trigger. In this case, the door body may already be in an open state. In a specific implementation, a pressure sensor may be provided in the door body of the household appliance, and the pressure sensor is used to detect whether the door body is in an open state or a closed state. When the door body is in an open state, if the automatic door opening device is still controlled to operate, the door opening force generated by it may not be released to the door body, causing the automatic door opening device to absorb it internally, causing damage to the structure of the automatic door opening device. In order to avoid this problem, before executing S240 to control the drive motor to rotate, the following S270 may also be executed.
[0100] S270: Check whether the door is in a closed state; if so, execute S240.
[0101] Detecting whether the door body is in a closed state is to obtain the state information output by the aforementioned pressure sensor to determine whether the door body is in an open state or a closed state.
[0102] In addition to providing the aforementioned automatic door opening control method, the embodiment of the present disclosure also provides an automatic door opening control device.
[0103] FIG3 is a schematic diagram of the structure of the automatic door opening control device provided by the embodiment of the present disclosure. As shown in FIG3 , the automatic door opening control device 300 provided by the embodiment of the present disclosure includes a control unit 301 .
[0104] The control unit 301 is used to control the rotation of the drive motor after receiving the door opening trigger command, and control the position detection component to detect the position of the intermediate transmission member; and control the drive motor to stop rotating after determining that the intermediate transmission member moves from the initial position to the target position and then leaves the target position.
[0105] In some embodiments, the position detection component is a two-state detection component; in response to the detection state of the position detection component switching from the first state to the second state, the controller determines that the intermediate transmission member moves from the initial position to the target position; in response to the detection state of the position detection component switching back from the second state to the first state, the controller determines that the intermediate transmission member leaves the target position.
[0106] In some embodiments, the automatic door opening control device 300 further includes a detection unit. Before controlling the drive motor to rotate, the detection unit detects whether the door lock is in an unlocked state; when the door lock is in the unlocked state, the control unit 301 controls the drive motor to rotate.
[0107] In some embodiments, before controlling the driving motor to rotate, the detection unit detects whether the door lock is in an operating state. When the door lock is not in an operating state, the control unit 301 controls the driving motor to rotate.
[0108] In some embodiments, when the door lock is in an unlocked state, the control unit 301 first determines whether the current state of the home appliance meets the unlocking conditions. The home appliance is a device equipped with an automatic door opening device and a door lock. If the current state of the home appliance meets the unlocking conditions, the control unit 301 controls the door lock to unlock. After the door lock completes the unlocking action, the control unit 301 again checks whether the door lock is in the unlocked state and controls the drive motor to rotate if the door lock is in the unlocked state.
[0109] In some embodiments, the household appliance is a clothing processing device; the control unit 301 determines that the current state of the clothing processing device does not meet the unlocking conditions when the water level in the clothing processing device is higher than the set water level, or the clothing processing temperature of the clothing processing device is outside the safe temperature range, or the clothing processing device is in a rotating state.
[0110] In some embodiments, the control unit 301 detects whether the child lock function of the home appliance is turned on; when the child lock function is turned on the home appliance, the control unit 301 determines that the current state of the home appliance does not meet the unlocking condition.
[0111] In some embodiments, before controlling the driving motor to rotate, the control unit 301 first detects whether the door body is in a closed state; when it is determined that the door body is in a closed state, the control unit 301 controls the driving motor to rotate.

Industrial Applicability
[0117] The present disclosure provides an automatic door opening control method, device, and household appliance. The automatic door opening control method is used to control the automatic door opening device to automatically open the door body. After receiving the door opening trigger command and controlling the drive motor to rotate, the controller controls the drive motor to stop rotating after the intermediate transmission member moves to the target position and leaves the target position. Because the target position indicates that the door opening actuator has achieved door opening, or indicates that the door opening actuator can achieve door opening during the return movement process, when it is determined that the intermediate transmission member has left the target position, it is determined that the door body has been opened by the door opening actuator. At this time, the drive motor can be controlled to stop rotating, which has strong industrial applicability.
