[0041] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.
[0042] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.
[0043] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a series of components is not necessarily limited to those that are explicitly listed, but may include other components that are not explicitly listed or that are inherent to such product or device.
[0044] With the development of technology, users have increasingly higher demands for the intelligence and ease of operation of smart home appliances and other devices. Take refrigerators as an example. A refrigerator is a refrigeration device that stores food or other items at a constant low temperature and has become one of the most commonly used household appliances. As people's living standards improve, their requirements for the functionality and user experience of refrigerators are also increasing. However, existing refrigerators are usually relatively simple in function, resulting in poor convenience and user experience.
[0045] Therefore, this application proposes a method to assist users in opening and closing the refrigerator door, thereby improving the convenience of using the refrigerator and enhancing the user experience.
[0046] The technical solutions of this application will be described in detail below with reference to specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0047] first, Figure 1 This is a structural schematic diagram of a refrigerator provided in this application. Figure 1 As shown, the refrigerator may include a door, a door drive mechanism, and a control device. The door drive mechanism may include an angle detection module and a door drive module. The door drive mechanism can be mounted on the door. The control device can be connected to the angle detection module and the door drive module. By incorporating the angle detection module into the door drive mechanism, the integration of the refrigerator components is improved, thereby enhancing the convenience and safety of using the refrigerator.
[0048] Optionally, each door of the refrigerator may correspond to one of the aforementioned door drive devices. Alternatively, the refrigerator may have only refrigerator compartment doors, or only freezer compartment doors may have the aforementioned door drive devices.
[0049] It should be understood that this application does not limit the installation position or method of the aforementioned door drive device on the door. For example, Figure 2 A schematic diagram of another refrigerator provided in this application. Figure 2 As shown, the door drive device can be installed above the door near the refrigerator body. Furthermore, it should be understood that this application does not limit whether the refrigerator includes other devices. Moreover, this application does not limit other functions of the refrigerator, such as refrigeration and freezing functions.
[0050] Figure 3 This is a flowchart illustrating a refrigerator door opening and closing method provided in this application. The executing entity of this refrigerator door opening and closing method can be, for example, the aforementioned control device. Figure 3 As shown, the method may include the following steps:
[0051] S101. Obtain the rotation parameter values of the door through the angle detection module.
[0052] The rotation parameter values of the door can be used to characterize the rotation angle of the door. For example, these rotation parameter values can be voltage, current, resistance, pressure, etc. Optionally, the magnitude of these rotation parameter values can be positively correlated with the rotation angle of the door, or negatively correlated with it. Taking voltage as an example, a larger voltage value obtained by the control device indicates a larger rotation angle of the door, while a smaller voltage value indicates a smaller rotation angle.
[0053] Optionally, the control device can, for example, obtain the rotation parameter value of the door through an angle detection module when it detects that the user has started to open or close the refrigerator door. Alternatively, the control device can, for example, continue to periodically execute step S101 after the refrigerator is powered on. Or, the control device can, for example, continue to periodically execute step S101 after the user has activated the user-assisted door opening and closing function.
[0054] S102. When the door's rotation parameter value is used to determine the door's transmission direction as the target direction, the door drive module controls the door to rotate in the target direction.
[0055] The target direction mentioned above can be either the opening direction or the closing direction.
[0056] For example, taking the above-mentioned rotation parameter value as voltage, and the voltage value being positively correlated with the rotation angle of the door, the control device can, for example, determine the door's transmission direction as the opening direction when the voltage is greater than the voltage at the previous moment, and determine the door's transmission direction as the closing direction when the voltage is less than the voltage at the previous moment.
[0057] Optionally, the control device controls the door to rotate in the target direction via a door drive module. For example, it can refer to any existing method for controlling the automatic opening and closing of a refrigerator door, which will not be elaborated upon here. For instance, if the door drive module includes a motor, the control device can control the rotation direction of the motor, causing the door to rotate in the target direction.
[0058] In this embodiment, the control device can obtain the rotation parameter value of the door, which characterizes the rotation angle of the door, through the angle detection module. Then, based on the rotation parameter value, the control device can determine the door's transmission direction as the target direction and control the door to rotate in that direction through the door drive module. Through this method, the control device can first determine the rotation direction of the refrigerator door and then control the door to rotate in that direction. This allows the user to assist in opening and closing the refrigerator door through the door drive module, improving the convenience of using the refrigerator and thus enhancing the user experience.
[0059] The structure of the angle detection module described above is illustrated below:
[0060] In one possible implementation, the angle detection module may include an angle detection unit. This angle detection unit may include a first rotating component. The door drive module may include a second rotating component. The angle detection unit can be connected to the second rotating component of the door drive module via the first rotating component. In this implementation, when the door rotates, the second rotating component rotates, and the second rotating component drives the first rotating component to rotate.
[0061] In this implementation, the control device can obtain the rotation parameter values of the door through the aforementioned angle detection unit. Specifically, the rotation parameter values obtained by the angle detection unit will differ depending on the rotation angle of the first rotating component.
[0062] For example, the second rotating component described above can be, for instance, a gear shaft component of the door drive module. For example, taking the angle detection unit as a potentiometer, the first rotating component can be, for instance, a rotating part of the potentiometer. The resistance value of the potentiometer varies when the rotating component rotates to different positions. For example, taking the angle detection unit as a potentiometer, for instance... Figure 4a This is a schematic diagram illustrating a connection method between a first rotating component and a second rotating component, as provided in this application. Figure 4a As shown, the second rotating component can be a gear shaft, and the protruding part of the gear shaft is connected to the first rotating component (potentiometer rotating part) of the potentiometer. The potentiometer fixing part is the non-rotatable part of the potentiometer. A circuit board can be located below the potentiometer fixing part.
[0063] In this embodiment, the angle detection unit is connected to the second rotating component of the door drive module through the first rotating component, so that when the door rotates, the second rotating component of the door drive module can drive the first rotating component to rotate. This allows the control device to detect different rotation parameter values by rotating the first rotating component to different positions, thereby obtaining the rotation parameter value of the door "to characterize the rotation angle of the door". This lays the foundation for determining the target direction of the door rotation based on the rotation parameter value of the door, and assisting the user in opening and closing the door based on the target direction.
[0064] Taking the aforementioned rotation parameter value as voltage as an example, optionally, the control device can acquire the voltage across the angle detection unit and determine the rotation parameter value of the door based on this voltage. The voltage across the angle detection unit can be positively correlated with the rotation angle of the door. That is, the larger the rotation angle of the door, the larger the voltage across the angle detection unit. The smaller the rotation angle of the door, the smaller the voltage across the angle detection unit.
[0065] Optionally, the control device can acquire the voltage across the angle detection unit in any existing voltage detection method, which will not be elaborated here. For example, the control device can directly use the voltage as the rotation parameter value of the door. Alternatively, the control device can amplify the voltage and use the amplified voltage as the rotation parameter value of the door, improving the accuracy of determining the rotation parameter value of the door when the voltage is low.
[0066] If the rotation parameter value of the door is less than the rotation parameter value of the door at the previous detection time, it indicates that the rotation angle of the door is decreasing, and therefore the control device can determine that the door's transmission direction is the closing direction. If the rotation parameter value of the door is greater than the rotation parameter value of the door at the previous detection time, it indicates that the rotation angle of the door is increasing, and therefore the control device can determine that the door's transmission direction is the opening direction. In some embodiments, if the rotation parameter value of the door is equal to the rotation parameter value of the door at the previous detection time, it indicates that the user may be controlling the door or that the door may be encountering an obstacle. Optionally, the control device can stop executing the operation of controlling the door to rotate in the target direction through the door drive module.
[0067] Using the above method, the rotation parameter value of the door can be determined based on the voltage at both ends of the angle detection unit, thus realizing the acquisition of the rotation parameter value of the door "used to characterize the rotation angle of the door". Furthermore, the transmission direction of the door can be determined based on the relationship between this rotation parameter value and the rotation parameter value of the door at the previous detection moment, laying the foundation for assisting users in opening and closing the door.
[0068] Taking the angle detection unit as a potentiometer as an example, optionally, the potentiometer can also form a series circuit with the target resistor and the target power supply.
[0069] For example, Figure 4b This is a schematic diagram of a potentiometer provided in this application. Figure 4c This is a schematic diagram of the internal structure of a potentiometer provided in this application. Figure 4b and Figure 4c As shown, the potentiometer may include: contact 1, contact 2, and contact 3, and an inner core. The internal structure may include a rotating contact and a carbon film body. The center hole of the potentiometer may be a non-circular hole, such as... Figure 4a The gear shaft shown in the diagram can be inserted into this hole. The gear shaft may have a protrusion, and when the gear shaft rotates, it can drive the rotating part of the potentiometer to rotate.
[0070] It should be understood that this application does not limit the resistance value of the target resistor or the voltage of the target power supply. For example, Figure 5 This is a schematic diagram of a series circuit provided in this application.
[0071] by Figure 5 Taking the series circuit shown as an example, assuming the target resistor has a resistance of 2000 ohms (Ω), the target power supply voltage is 12V, the potentiometer's rotation range is limited to 1000Ω to 4000Ω, and the potentiometer's resistance changes by 25Ω for every 1 degree the door rotates. Typically, a change within 5 degrees is sufficient for general needs. For example, the control device can take the door's rotation parameter value every 4 degrees of rotation, meaning the potentiometer's resistance changes by 100Ω each time. At the nth time (the nth moment after the door begins to rotate), the voltage difference across the potentiometer ΔV = 12*(1000+(n-1)*100) / (2000+1000+(n-1)*100), as shown in Table 1 below:
[0072] Table 1
[0073]
[0074]
[0075] The above-mentioned door drive module is illustrated below:
[0076] In one possible implementation, the aforementioned door drive module may include a motor and a clutch. The control device can be connected to the motor and the clutch. In this implementation, the control device can control the door to rotate in a target direction by energizing the clutch and controlling the motor to rotate. If the target direction is the opening direction, the motor rotation direction can be forward. If the target direction is the closing direction, the motor rotation direction can be reverse. By energizing the clutch and controlling the motor to rotate, the door drive module controls the door to rotate in the target direction, assisting the user in opening and closing the door and improving the user experience.
[0077] It should be understood that this application does not limit whether the aforementioned door drive module includes other components. Optionally, this application does not limit how the door drive module specifically controls the opening and closing of the refrigerator door via the aforementioned motor and clutch. For example, the refrigerator may also include a movable component. This movable component is provided with a connecting device and a first transmission component. The connecting device movably connects the movable component to the refrigerator body to close or open the opening of the refrigerator's storage compartment. The first transmission component is fixedly connected to the connecting device. The aforementioned door drive module can also be referred to as a door opening and closing drive device. This door opening and closing drive device is mounted on the refrigerator body or the movable component, and is composed of multiple components, one of which is the aforementioned clutch. The clutch can disengage or engage all or part of the multiple components with the first transmission component. When the clutch engages all or part of the multiple components with the first transmission component, the door opening and closing drive device can drive the movable component to automatically open or close via the connecting device. When the clutch disengages all or part of the multiple components from the first transmission component, the movable component can drive the connecting device to move, or drive some components of the connecting device and the door opening and closing drive device to move.
[0078] The aforementioned door opening and closing drive device may further include a drive component and a second transmission component. The drive component is drively connected to the second transmission component. The clutch includes a first half-clutch and a second half-clutch; the first half-clutch can disengage from or engage with the second transmission component, and the second half-clutch is drively connected to the first transmission component. The drive component may be the aforementioned motor.
[0079] As one possible implementation, the refrigerator can also use the control device to stop controlling the door to rotate in the target direction when the door's rotation parameter value reaches the first target rotation parameter value. The first target rotation parameter value is the door's rotation parameter value when the door is fully closed or fully open. This method ensures that after the refrigerator door has opened and closed, the door drive module no longer drives the door to rotate, preventing damage to the refrigerator door.
[0080] For example, taking the rotation parameter value as voltage, referring to Table 1 above, the first target rotation parameter value corresponding to the fully closed state of the door can be, for example, 4V. The first target rotation parameter value corresponding to the fully open state of the door can be, for example, 8V.
[0081] As one possible implementation, taking the target direction as the closing direction as an example, the control device can also control the door to rotate at a speed of less than a preset speed by using the door drive module when the door's rotation parameter value is the second target rotation parameter value.
[0082] The second target rotation parameter value can be the rotation parameter value corresponding to the rotation angle when the door is close to the fully closed state. For example, the second target rotation parameter value can be the rotation parameter value corresponding to any rotation angle that is less than the midpoint between "the rotation angle of the door in the fully closed state and the rotation angle of the door in the fully open state".
[0083] For example, still taking the rotation parameter value as voltage, referring to Table 1 above, the rotation angle when the door is fully closed can be 0, and the second target rotation parameter value corresponding to the rotation angle close to 0 can be any one of 4.26V-6V.
[0084] For example, the preset rotational speed can be pre-stored in the control device. Optionally, the control device can control the rotational speed of the motor in the door drive module according to the preset rotational speed, thereby reducing the rotational speed of the door in the target direction to the preset rotational speed.
[0085] In this implementation, during the closing process, the rotation speed of the door in the target direction is reduced when the door is close to being fully closed. This reduces the closing speed when the refrigerator door is about to close, thus reducing the possibility of the refrigerator door pinching a hand, improving the safety of using the refrigerator, and further enhancing the user experience.
[0086] For example, taking the above rotation parameter value as voltage, and the range of the above rotation parameter value as a voltage value, Figure 6 A flowchart illustrating another method for opening and closing a refrigerator door provided in this application. Figure 6As shown, the control module first acquires the initial voltage (i.e., the rotation parameter value acquired at the current moment: the voltage value across the potentiometer). When the voltage value per unit time is greater than the voltage value for the next angle, it can be determined that the user is manually opening the door, the trend-opening logic takes effect, the motor runs in the forward direction, the clutch is energized, and the user opens the door. Referring to Table 1 above, when the voltage value reaches 8V, it can be determined that the door has reached the opening limit position, and the motor and clutch are de-energized. For example, if the voltage across the potentiometer is about 6V, and Table 1 shows that the door angle is 40 degrees; if the voltage value is greater than 6.15V within a short period of time (e.g., 0.2s), it indicates that the door angle is increasing, and the user is attempting to open the door. Similarly, when the voltage value per unit time is less than the voltage value for the previous angle, it can be determined that the user is manually closing the door, the trend-closing logic takes effect, the motor runs in reverse, the clutch is energized, and the user closes the door. Referring to Table 1 above, when the voltage value reaches 4V, it can be determined that the door has reached the closing limit position, and the motor and clutch are de-energized.
[0087] For example, taking the aforementioned door drive device as an actuator (the mechanism that enables the refrigerator door to open and close automatically), Figure 7 This application provides an external view of an actuator. The actuator includes, but is not limited to, a motor, a gear set, and an electromagnetic clutch. The clutch functions to allow the motor to drive the hinge shaft to rotate via a worm gear and gear set. Due to the worm's self-locking action, the door cannot rotate even if the user forces it open or closes, as long as the motor is not energized. As mentioned earlier, the potentiometer can also be incorporated into the actuator. In this implementation, Figure 8 An exploded view of an actuator provided in this application. For example... Figure 8 As shown, the actuator may include a top cover, a chain, a DC motor, a gear set, a clutch, a base, a control board, a potentiometer, and a switch board. Optionally, how the actuator performs the opening and closing of the refrigerator door through the above structure can refer to any existing door drive device, which will not be described in detail here.
[0088] Using the above method, when the door is stationary, neither the motor nor the clutch is energized. When the user manually opens or closes the door, the actuator's potentiometer will sense the door's tendency to open or close. The control unit will issue a command, energize and engage the clutch, and the motor will rotate in the first or second direction to assist the user in completing the opening or closing action, making it convenient for the user.
[0089] Figure 9 This is a schematic diagram of a refrigerator door opening and closing device provided in an embodiment of this application. This device can be used in the control device of the refrigerator described in any of the foregoing embodiments. Figure 9 As shown, the device may include: an acquisition module 21 and a processing module 22, wherein:
[0090] The acquisition module 21 is used to acquire the rotation parameter values of the door body through the angle detection module. The rotation parameter values of the door body are used to characterize the rotation angle of the door body.
[0091] The processing module 22 is used to control the door to rotate in the target direction via the door drive module when the door's transmission direction is determined to be the target direction based on the door's rotation parameter values. The target direction is either the opening direction or the closing direction.
[0092] Optionally, the angle detection module includes an angle detection unit, which includes a first rotating component, and the door drive module includes a second rotating component. The angle detection unit is connected to the second rotating component of the door drive module via the first rotating component. When the door rotates, the second rotating component rotates, and the second rotating component drives the first rotating component to rotate. Optionally, the acquisition module 21 is specifically used to acquire the rotation parameter values of the door through the angle detection unit. Wherein, different rotation angles of the first rotating component result in different rotation parameter values acquired by the angle detection unit.
[0093] Taking the rotation parameter value as voltage as an example, optionally, the acquisition module 21 is specifically used to acquire the voltage across the angle detection unit and determine the rotation parameter value of the door based on the voltage. The voltage across the angle detection unit is positively correlated with the rotation angle of the door. Optionally, the processing module 22 is specifically used to determine the door's transmission direction as the closing direction when the door's rotation parameter value is less than the door's rotation parameter value at the previous detection time. When the door's rotation parameter value is greater than the door's rotation parameter value at the previous detection time, it is determined that the door's transmission direction is the opening direction.
[0094] Optionally, the angle detection unit is a potentiometer, which also forms a series circuit with the target resistor and the target power supply.
[0095] Optionally, the door drive module includes a motor and a clutch. Optionally, a processing module 22 is used to control the door to rotate in the target direction by energizing the clutch and controlling the motor to rotate. Wherein, if the target direction is the opening direction, the motor rotates forward; if the target direction is the closing direction, the motor rotates in the reverse direction.
[0096] Optionally, the processing module 22 is further configured to stop controlling the door to rotate in the target direction via the door drive module when the rotation parameter value of the door is a first target rotation parameter value. The first target rotation parameter value is the rotation parameter value of the door in either the fully closed state or the fully open state.
[0097] Taking the target direction as the closing direction as an example, optionally, the processing module 22 is further configured to, when the rotation parameter value of the door body is the second target rotation parameter value, control the rotation speed of the door body in the target direction to decrease to a preset speed through the door body driving module. Wherein, the second target rotation parameter value is the rotation parameter value corresponding to the rotation angle when the door body is close to the fully closed state.
[0098] The refrigerator door opening and closing device provided in this application embodiment can execute the refrigerator door opening and closing method in the above method embodiment. Its implementation principle and technical effect are similar, and will not be described again here.
