Description

Technical Field

[0001] The present disclosure relates to the technical field of household appliances, and particularly to an automatic door opening control method, device and household appliance equipment. Background Art

[0002] To achieve the convenience of using household appliance equipment such as washing machines, related technologies propose to set an automatic door opening device in the household appliance equipment. After the household appliance equipment completes the main function, by controlling the action of the automatic door opening device, the automatic door opening device applies a force to the door body to realize the automatic opening of the door body. When the user wants to actively control the door opening of the household appliance equipment, by operating the control button to send an opening instruction to the automatic door opening device, the automatic opening of the door body can also be realized.

[0003] In specific implementation, the automatic door opening device includes a driving motor, a transmission mechanism, a door opening execution mechanism and a position detection component. Among them, the position detection component determines that the door opening execution mechanism has moved to a specific state by detecting the position of a specific transmission component in the transmission mechanism. Subsequently, after controlling the driving motor to rotate for a specific duration, the opening of the door body can be realized and the door opening execution mechanism can be reset. However, the foregoing control strategy for controlling the action of the door opening execution mechanism does not have negative feedback. In the case of a large load, although the control motor rotates for a set duration, it cannot ensure that the door body has been automatically opened and the specific transmission component has been correctly reset.

[0036] The following will describe the embodiments of the present disclosure in more detail with reference to the drawings. Although some embodiments of the present disclosure are shown in the 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. Instead, these embodiments are provided to more thoroughly and completely understand the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not used to limit the protection scope of the present disclosure.

The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments".

[0038] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly specified in the context, it should be understood as "one or more".

[0039] To solve the problem that when controlling the opening of an automatic door device in the prior art, after the position detection component detects that a specific transmission component in the transmission mechanism moves to the target position, the driving motor runs for a set duration and then powers off, the door may not be automatically opened or the specific transmission component may not be correctly reset. An embodiment of the present disclosure provides a new automatic door opening control method.

[0040] To more clearly understand the automatic door opening control method provided by the embodiments of the present disclosure, the following first gives a brief introduction to the automatic door opening device.

[0041] As generally introduced in the background art, the automatic door opening device includes a driving motor, a transmission mechanism, a door opening actuator, and a position detection component. In addition, a return elastic member is provided in the automatic door opening device.

[0042] The driving motor is used to generate the power for driving the door opening actuator to act.

[0043] The transmission mechanism is used to convert the rotational motion of the driving motor into other types of motion, and to amplify the torque generated when the driving motor rotates, so that a driving motor with a smaller power can be used to drive the door opening actuator to act. In some embodiments, the transmission mechanism may adopt a gear transmission mechanism to convert the rotational force generated by the driving motor into a rotational force with a larger torque through a plurality of gear transmission pairs. In some other embodiments, the transmission mechanism may also adopt mechanisms such as a crank-slider mechanism or a crank-rocker mechanism that can convert rotational motion into translational motion or oscillating motion.

[0044] In the embodiments of the present disclosure, an intermediate transmission member is provided in the transmission mechanism. The intermediate transmission member may be a translational member, a swinging member, or a rotating member. In practical applications, considering that the transmission mechanism should save space as much as possible, the aforementioned intermediate transmission member is preferably set as a translational member.

[0045] The door opening actuator is a mechanism for applying power to the door body and then realizing the opening of the door body. In some embodiments, the door opening actuator may be a cam mechanism, which applies a force to the door latch by the rotation of the cam, and uses the door latch to drive the door body to move to realize the automatic opening of the door body.

[0046] The position detection component is used to detect the position of the intermediate transmission component of the aforementioned transmission mechanism, and to determine the action state of the door opening actuator through the position of the intermediate transmission component, and then to determine whether the automatic door opening device has correctly executed the door opening operation.

[0047] In specific implementation, the position detection component may be a Hall sensor, a distance detection sensor, or a mechanical switch, etc. Preferably, a two-state detection component such as a Hall switch or a mechanical switch is adopted. It should be noted that when the distance detection sensor is a Hall switch, there should be a metal component or a magnetic component at a specific position in the intermediate transmission member.

[0048] The return 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 driving motor cannot be applied to the intermediate transmission member.

[0049] The following analyzes the automatic door opening control method provided by the embodiments of the present disclosure. Figure 1 It is a flowchart of the automatic door opening control method provided by the embodiments of the present disclosure. As Figure 1 shown, the automatic door opening control method provided by the embodiments of the present disclosure includes S110 - S120.

[0050] It should be noted that the automatic door opening control method provided by the embodiments of the present disclosure is controlled and executed by the controller in the device equipped with the automatic door opening device. The aforementioned device equipped with the automatic door opening device can be various types of household appliances, such as clothing processing devices like washing machines and dryers, or devices like microwave ovens and electric ovens.

[0051] S110: Determine that a door opening trigger instruction is received, control the driving motor to rotate, and control the position detection component to detect the position of the intermediate transmission member.

[0052] The door opening trigger instruction is an instruction for controlling the automatic door opening device to perform a door opening action. In some embodiments, the door opening trigger instruction can be generated by the user through operating the device equipped with the automatic door opening device, or 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.

[0053] As previously analyzed, the automatic door opening device generates the power to open the door body by the rotation of the driving motor. Correspondingly, the received door opening trigger instruction is also an instruction for controlling the rotation of the driving motor. In the embodiments of the present disclosure, after receiving the door opening trigger instruction, the controller controls the switch connected in series with the driving motor to close, realizing the conduction of the current in the circuit where the driving motor is located, and then controlling the driving motor to rotate.

[0054] In the embodiments of the present disclosure, while controlling the driving motor to rotate, the controller will control 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, so that the position sensor can detect the position of the intermediate transmission member.

[0055] When the structure of the automatic door opening device is normal, after the driving motor is powered on and rotates, the driving motor will drive the door opening actuator to act through the transmission mechanism. While the transmission mechanism is acting, the intermediate transmission member in the transmission mechanism will move from the initial position to the target position. The target position is the position that represents that the door opening actuator has opened the door body, or indicates that the door body can be opened during the backward movement of the door opening actuator. 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 has opened. It should be noted that the target position mentioned in the embodiments of the present disclosure can be a position point or a position interval.

[0056] In the embodiments of the present disclosure, when the intermediate transmission member moves to the target position or after moving to the target position for a period of time, the power generated by the driving motor cannot be applied to the intermediate transmission member due to the change in the connection relationship between the transmission components, and thus cannot be transmitted to the door opening actuator through the intermediate transmission member. Subsequently, the elastic force generated by the compression of the return elastic member will be applied to the intermediate transmission member, causing the intermediate transmission member to move back and move out from the target position.

[0057] S120: Determine that the intermediate transmission member moves away from the target position after moving from the initial position to the target position, and control the driving motor to stop rotating.

[0058] As analyzed above, the target position represents the position where the door opening actuator has achieved the opening of the door body, or indicates that the door body can be opened during the backward movement of the door opening actuator. That is to say, if the intermediate transmission member moves from the initial position to the target position and then moves away from the target position, it can be determined that the door opening actuator has achieved the opening of the door body, and at this time, the driving motor can be controlled to stop rotating.

[0059] Using the automatic door opening control method provided by the embodiments of the present disclosure, after receiving the door opening trigger command and controlling the driving motor to rotate, the controller controls the driving motor to stop rotating only after the intermediate transmission member moves to the target position and then moves away from the target position. Since the target position represents the position where the door opening actuator has achieved the opening of the door body, or indicates that the door body can be opened during the backward movement of the door opening actuator, when it is determined that the intermediate transmission member has moved away from the target position, it is determined that the door body has been opened by the door opening actuator at this time, and the driving motor can be controlled to stop rotating at this time.

[0060] In the related art, when it is determined that the intermediate transmission member moves to the target position, the motor is controlled to stop rotating, or when it is determined that a certain time has elapsed after the intermediate transmission member moves to the target position, the driving motor is controlled to stop rotating again. There may be a problem that the intermediate transmission member is stuck at a non-initial position, and although the door opening has not been completed, the controller mistakenly believes that the door opening has been completed. By adopting the solution of the embodiments of the present disclosure, after detecting that the intermediate transmission member moves to the target position, it is further detected whether the intermediate transmission member moves away from the target position. Only after the intermediate transmission member moves away from the target position, it is determined that the door opening execution ends, ensuring that the automatic door opening device completes a complete door opening action, avoiding the problem that the door opening action is not completed but is mistakenly considered to be completed, and improving the reliability of automatic door opening.

[0061] As mentioned above, the position detection component in some embodiments of the present disclosure can be a real-time position detection component such as a distance detection sensor. In this case, the controller can determine the real-time position of the intermediate detection component according to the distance signal generated by the distance detection sensor, and then determine whether the intermediate transmission member moves to the target position and whether it moves away from the target position.

[0062] In some 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 S121-S122.

[0063] S121: In response to the detection state of the position detection component switching from the first state to the second state, determining that the intermediate transmission member moves from the initial position to the target position.

[0064] In the embodiment 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 is a state of outputting a high level.

[0065] If the position detection component switches from the first state to the second state, it is determined that the position detection component switches from a state where the intermediate transmission component is not triggered to a state where the intermediate transmission component is detected and triggered, that is, the intermediate transmission component has moved to a position close to or even close to the position detection component. The aforementioned position is pre-set as the target position, so at this time it can be determined that the intermediate transmission component has moved from its initial position to the target position.

[0066] 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.

[0067] 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 triggered by the intermediate component to the state no longer triggered by the intermediate transmission detection, and at this time it is determined that the intermediate transmission component has left the target position.

[0068] Figure 2 FIG. 1 is a flow chart of an automatic door opening control method provided by another embodiment of the present disclosure. Figure 2 As shown, some other embodiments provide automatic door opening control methods including S210-S250.

[0069] 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.

[0070] S220: Control the door lock to perform an unlocking operation and detect whether the door lock is in an action state; if so, continue to execute S220; if not, execute S230.

[0071] S230: Detect whether the door lock has been switched to the unlocked state; if so, execute S240; if not, execute S220.

[0072] S240: Control the driving motor to rotate and control the position detection component to detect the position of the intermediate transmission member.

[0073] S250: Determine that after the intermediate transmission member moves from the initial position to the target position and then leaves the target position, control the driving motor to stop rotating.

[0074] In practical applications, in order to ensure the safety of the household appliance during operation, the household appliance is equipped with a locking member, and the door body is locked by the door locking member during operation to prevent the door body from being opened due to a strong force. For example, a drum washing machine applies a door lock during operation so that the door body will not be opened due to internal thrust or external pulling force.

[0075] In order to avoid conflicts between the working state of the automatic door opening device and the locked state of the door lock during the door opening operation, in the embodiments of the present disclosure, after receiving the door opening trigger instruction, it is first detected whether the door lock is in the unlocked state.

[0076] If the door lock is in the unlocked state, at this time, the automatic door opening device can be controlled to perform the door opening action, that is, control the driving motor to rotate and control the position detection component to detect the position of the intermediate transmission member.

[0077] If the door lock is not in the unlocked state, then the door lock may be in two states at this time: (1) The door lock is in the locked state; (2) The door lock is in the action state, and this action state may be the action state from locked to unlocked or the action state from unlocked to locked.

[0078] In the embodiments 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, control the door lock to perform the action of switching from the locked state to the unlocked state. At this time, it can be detected 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 unlocked successfully, so it is still necessary to detect whether it is in the action state. If the door lock has completed the unlocking action, in order to avoid problems such as unlocking errors or unsuccessful unlocking, it is then necessary to determine again whether the door lock is unlocked successfully, that is, determine whether the door lock has been unlocked successfully, so that the driving motor can be controlled to rotate and the position moving component can be controlled to detect the position of the intermediate transmission member to determine whether the automatic door opening operation has been correctly executed.

[0079] The specific implementation methods of S240 - S250 in the embodiments of the present disclosure are the same as those in the previous embodiments and will not be repeated here. For details, please refer to the previous analysis.

[0080] As analyzed above, the door lock is to ensure the safety of the home appliance during use, and is locked when the home appliance is determined to be in the running state. In actual application, if the door lock is controlled to perform the unlocking operation after receiving the door opening trigger command and detecting that the door lock is not in the unlocking state, a safety accident may occur. To avoid this problem, in some embodiments, before executing the aforementioned S220, the controller also executes the following S250.

[0081] S250: Determine whether the current state of the home appliance meets the unlocking condition; if so, execute S220.

[0082] 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 according to the state of the operation being performed by the household appliance.

[0083] In some embodiments, the household 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 household appliance satisfies the unlocking condition may be different accordingly.

[0084] 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.

[0085] For another example, if the household 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.

[0086] In some other embodiments, the household appliance is a microwave oven, and 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.

[0087] It should be noted here that if the determination of whether the current state of the home appliance meets the unlocking condition includes multiple determination conditions, the unlocking operation cannot be performed if only one determination condition does not meet the unlocking condition. Conversely, the unlocking operation can only be performed if all the unlocking conditions are met.

[0088] 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.

[0089] In some embodiments, although the current state of the household appliance satisfies the unlocking condition, in order to prevent children from opening the door and causing various problems, the subject device may activate the child lock function. At this time, before executing the foregoing S220, the controller also needs to execute the following S260.

[0090] S260: Detect whether the child lock function of the laundry treatment device is activated; if not, execute S220.

[0091] If the child lock function of the laundry treatment device is activated, at this time, the lock is in the locked state, and the laundry treatment device cannot be controlled to perform the unlocking operation. At this time, a corresponding prompt message can be generated to prompt the user that the child lock is currently activated and the unlocking operation and the door opening operation can only be performed after the child lock is released.

[0092] In some embodiments, the door opening trigger instruction may be generated by the user's touch. In this case, the door may already be in the open state. In a specific implementation, a pressure sensor may be provided in the door of the household appliance, and the pressure sensor is used to detect whether the door is in the open state or the closed state. When the door is in the open state, if the automatic door opening device is still controlled to act, it may cause the opening force generated by it to be unable to be released to the door and be absorbed inside the automatic door opening device, resulting in damage to the structure of the automatic door opening device. To avoid this problem, before executing S240 to control the driving motor to rotate, the following S270 can also be executed.

[0093] S270: Detect whether the door is in the closed state; if so, execute S240.

[0094] Detecting whether the door is in the closed state is to obtain the status information output by the foregoing pressure sensor and determine whether the door is in the open state or the closed state.

[0095] In addition to providing the foregoing automatic door opening control method, the embodiments of the present disclosure also provide an automatic door opening control device. Figure 3 is a schematic structural diagram of the automatic door opening control device provided by the embodiments of the present disclosure. As Figure 3 shown, the automatic door opening control device 300 provided by the embodiments of the present disclosure includes a control unit 301.

[0096] The control unit 301 is configured to control the driving motor to rotate and control the position detection component to detect the position of the intermediate transmission member after receiving the door opening trigger instruction; and control the driving 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.

[0097] 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.

[0098] In some embodiments, the automatic door opening control device 300 further includes a detection unit. Before controlling the driving motor to rotate, the detection unit detects whether the door lock is in the unlocked state; when the door lock is in the unlocked state, the control unit 301 controls the driving motor to rotate.

[0099] In some embodiments, before controlling the driving motor to rotate, the detection unit detects whether the door lock is in the operating state. When the door lock is not in the operating state, the control unit 301 controls the driving motor to rotate.

[0100] In some embodiments, when the door lock is in the unlocked state, the control unit 301 first determines whether the current state of the household electrical appliance satisfies the unlocking condition, and the household electrical appliance is an appliance configured with an automatic door opening device and a door lock. When it is determined that the current state of the household electrical appliance satisfies the unlocking condition, the control unit 301 controls the door lock to perform an unlocking action; after the door lock finishes the unlocking action, it detects again whether the door lock is in the unlocked state, and controls the driving motor to rotate when it is determined that the door lock is in the unlocked state.

[0101] In some embodiments, the household electrical appliance is a laundry treatment device; the control unit 301 determines that the current state of the laundry treatment device does not satisfy the unlocking condition when the water level in the laundry treatment device is higher than the set water level, or the laundry treatment temperature of the laundry treatment device is outside the safe temperature range, or the laundry treatment device is in a rotating state.

[0102] In some embodiments, the control unit 301 detects whether the household electrical appliance has the child lock function enabled; when the household electrical appliance has the child lock function enabled, the control unit 301 determines that the current state of the household electrical appliance does not satisfy the unlocking condition.

[0103] In some embodiments, before controlling the driving motor to rotate, the control unit 301 first detects whether the door body is in the closed state; when it is determined that the door body is in the closed state, the control unit 301 controls the driving motor to rotate.

[0104] In addition to providing the foregoing automatic door opening control method and automatic door opening control device 300, an embodiment of the present disclosure further provides a household appliance. The household appliance includes a door body, a controller, and an automatic door opening device. The automatic door opening device includes the foregoing drive motor, gear transmission mechanism, door opening execution mechanism, and position detection component, wherein the gear transmission mechanism includes an intermediate transmission member, and the position detection component is used to detect the position of the intermediate transmission member. The controller adopts the automatic door opening control method mentioned above to control the operation of the drive motor of the automatic door opening device.

[0105] In specific implementation, the controller may be a central processing unit (CPU) or other forms of processing units with data processing capabilities and / or instruction execution capabilities, and can control other components in the water heating device to perform desired functions.

[0106] An embodiment of the present disclosure further provides a storage medium that stores a program or instructions, and the program or instructions cause a computer to execute any one of the automatic door opening control methods provided by the embodiments of the present disclosure. When the computer-executable instructions are executed by a computer controller, they can also be used to execute the above-mentioned arbitrary automatic door opening control methods provided by the embodiments of the present disclosure to achieve corresponding beneficial effects.
