Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, for example, to a method and device for controlling the switch of a refrigerator door, a refrigerator, and a computer-readable storage medium. Background Art

[0002] Automatic door opening and closing applies driving force to the door body through the driving device to drive the door body to move. If the driving force applied is too small, it may be difficult to overcome the resistance of the door opening and closing, and there will be a problem of insufficient driving force. If the driving force applied is too large, there will be risks such as hitting people and pinching hands.

[0003] In the related art, a current detection device is provided in the automatic door opening and closing system to detect the operating current of the driving device. When the operating current exceeds the preset safety current, the driving motor is controlled to stop running. In this way, since the operating current of the driving device is proportional to the driving force applied by the driving device to the door body, by detecting the operating current of the driving device and setting the preset safety current, the maximum driving force that the driving device can generate can be set, thereby reducing the safety hazards of the automatic door opening and closing.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] For a rotary type automatic door, when the door is opened at a small angle, the resistance to opening and closing the door is large. Therefore, the demand for driving force during the automatic door opening and closing process is different. When the door is opened at a small angle, a large driving force is required, and when the door is opened at a large angle, a small driving force is required. Although the related technology can limit the maximum driving force generated by the driving device and reduce safety hazards, it is easy to cause the problem of insufficient driving force when the door is opened at a small angle.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0048] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure.

[0052] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0053] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0054] More comprehensive and convenient automation is the development direction of many household appliances. Therefore, many storage appliances, including refrigerators, are equipped with doors that can be opened and closed automatically.

[0055] In order to improve the safety of automation, doors that can be opened and closed automatically are often equipped with protection measures such as current detection to limit the driving force applied to the door within a smaller range and reduce safety hazards. However, due to factors such as vertical beams, stops, and negative pressure, the door of the refrigerator is subject to greater resistance when the opening angle is small, and the required driving force is also greater. In this case, the limited smaller driving force may be difficult to meet the driving force requirements for opening and closing the door.

[0056] Combination Figure 1 The system for controlling the opening and closing of the refrigerator door includes a refrigerator 10, a user 20, and other facilities 30. When the door of the refrigerator 10 is automatically opened and closed, it may collide with the user 20 or other facilities 30, and other accidents.

[0057] Combination Figure 2 , Figure 3 As shown, the refrigerator 10 includes a door body 101, a driving device 102 and a processor (not shown in the figure).

[0058] The refrigerator 10 automatically opens or closes the door 101 under certain conditions or after receiving a door opening or closing command. The driving device 102 provides a driving force for opening or closing the door 101. Figure 2 As shown, during the opening and closing process of the door body 101, when the opening angle of the door body 101 is large, a large space is required, and it is more likely to cause safety accidents such as collisions with users or other facilities. Therefore, the driving force used to open and close the door body 101 is usually controlled within a small range. Figure 3 As shown, when the opening angle of the door body 101 is small, the required space is small and the possibility of safety accidents is low. However, in this case, the resistance that the door body 101 needs to overcome when opening and closing is large, and the small driving force may be difficult to meet the driving force requirements of the door body 101 opening and closing.

[0059] Combination Figure 4 The present disclosure provides a method for controlling the opening and closing of a refrigerator door, comprising:

[0060] S101, an angle detection device detects the opening angle of a door body.

[0061] S102, the processor adjusts the driving force of the driving device according to the opening angle of the door body; wherein, the smaller the opening angle of the door body is, the greater the driving force of the driving device is.

[0062] In this way, by detecting the opening angle of the door body and adjusting the driving force of the driving device on the door body according to the opening angle of the door body, a larger driving force can be provided when the opening angle of the door body is small, the resistance is large, and the safety hazard is small, so as to meet the door opening and closing requirements. In addition, a smaller driving force can be provided when the opening angle of the door body is large, the resistance is small, and the safety hazard is large, so as to reduce the safety hazard. Thus, a suitable driving force can be provided during the automatic door opening and closing process.

[0063] Optionally, the driving force of the driving device on the door body is adjusted according to the opening angle of the door body, including: when the opening angle of the door body is in the second interval, the driving device is controlled to apply a third driving force to the door body. When the opening angle of the door body is in the first interval, the driving device is controlled to apply a first driving force to the door body. The angle in the second interval is smaller than the angle in the first interval, and the third driving force is greater than the first driving force. In this way, the driving forces corresponding to different intervals can be determined by dividing the opening angle of the door body into intervals. The interval with a smaller opening angle of the door body corresponds to a larger driving force, so that the driving force of the driving device can be adjusted according to the angle of the door body to provide a suitable driving force during the automatic opening and closing of the door.

[0064] For example, the second interval is [0, 27°), and the first interval is [27°, 125°]. Or, the second interval is [0, 30°), and the first interval is [30°, 130°].

[0065] Specifically, the driving device includes a first driving motor and a second driving motor. During the process of opening and closing the door, the first driving motor continuously provides driving force. Adjusting the driving force of the driving device on the door includes: adjusting the driving force of the driving device on the door by controlling the second driving motor. In this way, by adding a second driving motor, the two driving motors can simultaneously drive the door to move when the opening angle of the door is small, providing a greater driving force, and providing a suitable driving force during the process of automatically opening and closing the door.

[0066] Furthermore, the driving force on the door body is adjusted by controlling the second driving motor, including: when the opening angle of the door body is within the second interval, the first driving motor and the second driving motor are controlled to run simultaneously, the first driving motor generates a first driving force, the second driving motor generates a second driving force, the combined force of the first driving force and the second driving force is a third driving force, and the door body is driven to move by the third driving force. When the opening angle of the door body is within the first interval, the second driving motor is controlled to be closed, the first driving motor is operated to generate the first driving force, and the door body is driven to move by the first driving force.

[0067] Combination Figure 5 The present disclosure provides another method for controlling the opening and closing of a refrigerator door, comprising:

[0068] S201, the angle detection device detects the opening angle of the door body.

[0069] S202, the processor determines the range of the door opening angle.

[0070] S203, when the opening angle of the door body is within the second interval, the processor controls the first drive motor and the second drive motor to run simultaneously, the first drive motor generates a first driving force, the second drive motor generates a second driving force, the combined force of the first driving force and the second driving force is a third driving force, and the door body is driven to move by the third driving force.

[0071] S204, when the door opening angle is within the first interval, the processor controls the second drive motor to turn off, and the first drive motor to operate to generate a first drive force, and the door is driven to move by the first drive force.

[0072] Thus, compared with the commonly used method of driving the door body opening and closing with a single drive motor, the embodiment of the present disclosure can provide a greater driving force by adding a second drive motor when the door body is opened at a small angle. When the door body is opened at a large angle, the second drive motor does not run, and only the first drive motor generates a driving force to provide the same driving force as in the prior art for the door body opening and closing. Thus, through the corresponding relationship between the angle interval and the two working modes, a suitable driving force is provided according to the opening angle of the door body during the automatic door opening and closing process.

[0073] Optionally, regulating the driving force of the drive device on the door body includes: adjusting the driving force of the drive device on the door body by controlling the rotational speed of the first drive motor. Wherein, when the opening angle of the door body is within the second interval, the rotational speed of the first drive motor is higher than the rotational speed of the first drive motor when the opening angle of the door body is within the first interval. In addition to adjusting the driving force of the drive device on the door body by the second drive motor, the rotational speed of the drive motor can be changed on the basis of the existing single-motor drive technology, thereby changing the output driving force. By establishing a mapping relationship between the interval where the door body opening angle is located and the rotational speed of the drive motor, it is also possible to provide a suitable driving force according to the opening angle of the door body during the automatic opening and closing of the door.

[0074] Optionally, the refrigerator further includes a current detection device, which is used to detect the current of the driving device. The method for controlling the opening and closing of the refrigerator door further includes: when the current detected by the current detection device is greater than a safety current threshold, controlling the driving device to stop driving the door. The safety current threshold is determined according to the angle at which the door is opened. The driving force generated by the driving device is positively correlated with the current of the driving device, and the maximum driving force that the driving device can generate can be limited by setting the safety current threshold.

[0075] Combination Figure 6 The present disclosure provides another method for controlling the opening and closing of a refrigerator door, comprising:

[0076] S301, the angle detection device detects the opening angle of the door body.

[0077] S302, the processor determines the range of the door opening angle.

[0078] S303, when the opening angle of the door body is within the second interval, the processor controls the first drive motor and the second drive motor to run simultaneously, the first drive motor generates a first driving force, the second drive motor generates a second driving force, the combined force of the first driving force and the second driving force is a third driving force, and the door body is driven to move by the third driving force.

[0079] S304, when the door opening angle is within the first interval, the processor controls the second drive motor to turn off, and the first drive motor to operate to generate a first drive force, and the door is driven to move by the first drive force.

[0080] S305, the current detection device detects the current of the driving device.

[0081] S306, when the door opening angle is within the second interval and the current detected by the current detection device is greater than the second threshold, the processor controls the driving device to stop running.

[0082] The value range of the second threshold is 1.6 A to 2.0 A. For example, the second threshold may be 1.8 A or 1.9 A.

[0083] S307, when the door opening angle is within the first interval and the current detected by the current detection device is greater than the first threshold, the processor controls the driving device to stop running.

[0084] The value range of the first threshold is 1.0 A to 1.4 A. For example, the first threshold may be 1.2 A or 1.3 A.

[0085] In this way, the maximum driving force that the driving device can generate can be limited by setting the safety current threshold, which can reduce the potential safety hazards during the door opening and closing process. And according to the opening angle of the door, the safety current threshold is determined, which can provide a more appropriate driving force during the door opening and closing process.

[0086] The driving force required to open and close the door is also related to the width of the door. A wider door may require a greater driving force to drive. Figure 7 This is a schematic diagram of a refrigerator with asymmetrical door width. Figure 7 As shown, for a door body with a larger width, the resistance it encounters during the opening and closing process, especially when the opening angle is extremely small, is greater.

[0087] Optionally, for a refrigerator with a larger door width, the door opening angle can be divided into three intervals, wherein the interval with the smallest door opening angle has the largest safety current threshold, so that the demand for greater driving force can be better met.

[0088] Optionally, the safety current threshold is determined according to the angle at which the door is opened, including: when the angle at which the door is opened is within a first interval, the safety current threshold adopts a first threshold. When the angle at which the door is opened is within a second interval, the safety current threshold adopts a second threshold. When the angle at which the door is opened is within a third interval, the safety current threshold adopts a third threshold. Wherein, the angle at which the door is opened in the first interval is greater than the angle at which the door is opened in the second interval, the angle at which the door is opened in the second interval is greater than the angle at which the door is opened in the third interval, the first threshold is less than the second threshold, and the second threshold is less than the third threshold.

[0089] Combination Figure 8 As shown, the embodiment of the present disclosure provides another method for controlling the opening and closing of a refrigerator door, comprising:

[0090] S401, the angle detection device detects the opening angle of the door body.

[0091] S402, the processor determines the range of the door opening angle.

[0092] S403: When the door opening angle is within a first interval, the processor uses a first threshold as a safety current threshold.

[0093] The opening angle of the door body is divided into three intervals, wherein the opening angle of the door body in the first interval is greater than the opening angle of the door body in the second interval, which is greater than the opening angle of the door body in the third interval.

[0094] The first threshold is a current value corresponding to a smaller driving force. For example, taking the above dual-motor drive as an example, the first threshold corresponds to the driving force generated by the driving device when the first driving motor is running and the second driving motor is not running.

[0095] S404: When the door opening angle is within the second interval, the processor uses the second threshold as the safety current threshold.

[0096] The second threshold is a current value corresponding to a larger driving force. The second threshold is greater than the first threshold. For example, taking the above dual-motor drive as an example, the first threshold corresponds to the driving force generated by the driving device when the first driving motor and the second driving motor are running together.

[0097] S405: When the door opening angle is within a third interval, the processor uses a third threshold as a safety current threshold.

[0098] Since the opening angle of the door body in the third interval is very small, the probability of safety accidents such as collision or hand pinching is very low. Therefore, the safety current threshold corresponding to the third interval can be larger.

[0099] The third threshold is a current value corresponding to a greater driving force. The third threshold is greater than the second threshold. For example, the third threshold is a limiting current. The limiting current is a protective current value when the motor is at risk of burning in extreme cases. When the current of the driving device is greater than the limiting current, the motor is at risk of burning.

[0100] Fig. 9 The corresponding relationship diagram between the door opening angle and the safety current threshold in the embodiment of the present disclosure. Wherein, I1 is the first threshold, I2 is the second threshold, I3 is the third threshold, the first interval is [0, θ1), the second interval is [θ1, θ2), and the third interval is [θ2, θ3]. Wherein, θ3 is the maximum opening angle of the door.

[0101] The value range of θ1 is (0, 10°), the value range of θ2 is [10°, 30°), and the value range of θ3 is [90°, 130°]. For example, θ1 is 5°, θ2 is 27°, and θ3 is 90°; or, θ1 is 7°, θ2 is 30°, and θ3 is 125°.

[0102] The value range of I1 is 1.0A to 1.4A. The value range of I2 is 1.6A to 2.0A. The value range of I3 is 2.5A to 3.1A. For example, I1 can be 1.2A, I2 can be 1.8A, and I3 can be 3.0A.

[0103] In this way, by dividing the door opening angle into three intervals and further relaxing the current and driving force restrictions in the interval with the smallest door opening angle, suitable door opening and closing driving force can be provided for refrigerators with wider doors and other greater driving force requirements.

[0104] Combination Fig.10 As shown, the embodiment of the present disclosure provides a device 40 for controlling the switch of a refrigerator door, including a processor 401 and a memory 402. Optionally, the device 40 may also include a communication interface 403 and a bus 404.

[0105] In addition, the logic instructions in the memory 402 described above may be implemented in the form of software functional units and when sold or used as independent products, may be stored in a computer-readable storage medium.

[0106] The memory 402 is a computer-readable storage medium that can be used to store software programs and computer executable programs, such as program instructions / modules corresponding to the method in the embodiment of the present disclosure. The processor 401 executes the function application and data processing by running the program instructions / modules stored in the memory 402, that is, the method for controlling the refrigerator door switch in the above embodiment is implemented.

[0108] Combination Fig.11 As shown, the embodiment of the present disclosure provides a refrigerator 50, including a refrigerator body with a door body 60 installed, and also includes an angle detection device (not shown in the figure), a drive device 70 and the device 40 for controlling the switch of the refrigerator door as described above, which are installed on the refrigerator body. The installation relationship described here is not limited to placement inside the refrigerator body, but also includes installation connections with other components of the refrigerator, including but not limited to physical connections, electrical connections or signal transmission connections. It can be understood by those skilled in the art that the device 40 for controlling the switch of the refrigerator door can be adapted to a feasible refrigerator body, thereby realizing other feasible embodiments.

[0109] The angle detection device is disposed on the refrigerator body, and is used to detect the opening angle of the door body 60. The driving device 70 is connected to the door body 60, and is used to apply a driving force to the door body 60 to control the door body 60 to open or close.

[0110] Optionally, the driving device 70 includes a driving assembly 701 , a first driving motor 702 , a first transmission assembly 704 , a second driving motor 703 and a second transmission assembly 705 .

[0111] Combination Fig.12 , Fig.13As shown, one end of the driving assembly 701 is connected to the door body 60, and is used to drive the door body 60 to move under the action of the driving force. The first driving motor 702 generates a first driving force. One end of the first transmission assembly 704 is connected to the other end of the driving assembly 701, and the other end is connected to the first driving motor 702, and is used to transmit the first driving force to the driving assembly 701. The second driving motor 703 generates a second driving force. One end of the second transmission assembly 705 is connected to the other end of the driving assembly 701, and the other end is connected to the second driving motor 703, and is used to transmit the second driving force to the driving assembly 701.

[0112] Specifically, the driving assembly 701 is divided into two parts: a driving gear 7011 and a driving rod 7012 . The driving gear 7011 is engaged with both the first transmission assembly and the second transmission assembly, and the driving rod 7012 is connected to the door body 60 .

[0113] Furthermore, combined with Fig.12 , Fig.13 As shown, the second transmission assembly 705 includes a first transmission part 706 and a second transmission part 707. One end of the first transmission part 706 is connected to the other end of the driving assembly 701. One end of the second transmission part 707 is connected to the second drive motor 703, and the other end is a movable free end, which can be connected or disconnected with the other end of the first transmission part 706. In this way, the connection between the second drive motor 703 and the door body 60 can be disconnected when the second drive motor 703 is not running, so that the movement of the door body 60 will not affect the second drive motor 703 through the second transmission assembly 705.

[0114] Optionally, combined Fig.12 , Fig.13 As shown, the first transmission assembly 703 includes a third transmission part 708 and a fourth transmission part 709. One end of the third transmission part 708 is connected to the other end of the driving assembly 701. One end of the fourth transmission part 709 is connected to the first driving motor 702, and the other end is a movable free end, which can be connected or disconnected with the other end of the third transmission part 708. In this way, the connection between the first transmission motor 702 and the door body 60 can be cut off in time, so that in the case of manual opening and closing of the door, the movement of the door body 60 will not affect the first driving motor 702 through the first transmission assembly 703.

[0115] Optionally, the angle detection device is a resistive angle sensor. Fig.12 , Fig.13 As shown, the resistive angle sensor includes a connecting gear 710 disposed inside the driving device 70 and connected to the first transmission part or the third transmission part. The connecting gear 710 is driven to rotate when the door body 60 rotates, thereby changing the resistance value of the resistive angle sensor to detect the opening angle of the door body 60.

[0116] Optionally, the first transmission part 706 includes two gears or three gears meshing with each other.

[0117] Optionally, the second transmission part 707 includes two or three gears meshing with each other. The largest gear in the second transmission part 707 is smaller than the largest gear in the first transmission part 706. In this way, the driving force generated by the second drive motor 703 is transmitted through the second transmission assembly 705 and amplified by the gear set, thereby increasing the driving force actually acting on the door body 60.

[0118] Optionally, the refrigerator 50 further includes a current detection device (not shown in the figure), which is disposed on the refrigerator body and is used to detect the current of the drive device 70 in real time. When the current detection device detects that the current exceeds the safety current threshold, the drive device 70 is controlled to stop generating the driving force. In this way, the magnitude of the driving force can be limited, reducing the potential safety hazards during the opening and closing of the door body 60.
