[0028] 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. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0029] The terms "first", "second", etc. in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0030] Unless otherwise stated, the term "plurality" means two or more.

[0031] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0032] 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.

[0033] 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.

[0034] Combination Figure 1 and Figure 2 As shown, the embodiment of the present disclosure provides a refrigerator, including: a motor, a transmission mechanism 1, a clutch 2, and an angle sensor. The transmission mechanism 1 is connected to the motor. The clutch 2 is engaged or opened with the transmission mechanism 1, and is used to transmit the driving force of the motor to the door body through the transmission mechanism 1. The angle sensor is connected to the door body driving gear through the connecting gear 3 to realize the door opening angle detection when the door body rotates.

[0035] Optionally, the refrigerator door body includes a first door body and a second door body. The motor includes a first motor for driving the first door body switch and a second motor for driving the second door body switch. The transmission mechanism 1 includes a first transmission mechanism connected to the first motor and a second transmission mechanism connected to the second motor. The clutch 2 includes a first clutch and a second clutch. The first clutch is engaged or opened with the first transmission mechanism, and is used to transmit the driving force of the first motor to the first door body through the first transmission mechanism. The second clutch is engaged or opened with the second transmission mechanism, and is used to transmit the driving force of the second motor to the second door body through the second transmission mechanism.

[0036] Optionally, the angle sensor includes: a resistive angle sensor. The resistive angle sensor is connected to the door driving gear via the connecting gear 3. When the door rotates, the connecting gear 3 is driven to rotate, and the resistance value of the resistive angle sensor changes, which is used to detect the door opening and closing angle in real time.

[0037] In the refrigerator provided by the embodiment of the present disclosure, when the clutch 2 is engaged with the transmission mechanism 1, the driving force of the motor is transmitted to the door body through the transmission mechanism 1, and when the clutch 2 and the transmission mechanism 1 are opened, the driving force of the motor is not transmitted to the door body through the transmission mechanism 1, and the driving force of the motor is cancelled, providing a structural basis for controlling the delayed opening of the clutch and the transmission mechanism for braking.

[0038] Combination Figure 4 As shown, the embodiment of the present disclosure provides a method for opening and closing a refrigerator door, comprising:

[0039] S401, the refrigerator determines the door opening angle in response to the door opening instruction.

[0040] S402, when the door opening angle is greater than or equal to the maximum angle value, the refrigerator controls the clutch and transmission mechanism to maintain the opening braking time to brake the door body.

[0041] By using the refrigerator door opening and closing method provided by the embodiment of the present disclosure, when the door opening angle is greater than or equal to the maximum angle value, the refrigerator reaches the maximum opening angle, but at this time the door body will continue to open to the maximum angle due to inertia. Figure 3-2 The clutch and transmission mechanism are controlled to open at a delayed time for braking, thereby offsetting the kinetic energy of the door body continuing to open, eliminating the movement trend of the door body, and keeping the door body stationary after opening to the maximum angle, preventing malfunction caused by the inertia of the door body, improving the safety of opening and closing the refrigerator door, and maintaining the safety of users.

[0042] Optionally, combined Figure 3-1 As shown, the maximum angle value can be 90°.

[0043] Optionally, the refrigerator controls the clutch and transmission mechanism to keep the braking time open to brake the door body, including: the refrigerator controls the clutch and transmission mechanism to keep the braking time open to brake the door body according to the door opening speed.

[0044] In this way, the door opening speed is different, and the kinetic energy is different when the door opening angle reaches the maximum opening angle. Controlling the clutch and transmission mechanism to keep the braking time open according to the door opening speed is conducive to better braking the door, thereby more accurately offsetting the kinetic energy of the door continuing to open and eliminating the movement tendency of the door.

[0045] Optionally, the refrigerator controls the clutch and transmission mechanism to keep the brake time open according to the door opening speed to brake the door body, including: the refrigerator determines the brake time according to the door opening speed. The refrigerator controls the clutch and transmission mechanism to keep the brake time open to brake the door body.

[0046] In this way, the door opening speed is different, and the kinetic energy is different when the door opening angle reaches the maximum opening angle, and the required braking time is also different. Controlling the clutch and transmission mechanism to keep the braking time open according to the door opening speed is conducive to better braking the door, thereby more accurately offsetting the kinetic energy of the door's continued opening and eliminating the door's movement tendency.

[0047] Optionally, the refrigerator determines the braking time according to the door opening speed, including: the refrigerator determines the braking time according to the positive correlation between the door opening speed and the refrigeration time.

[0048] In this way, the faster the door opening speed is, the greater the kinetic energy is when the door opening angle reaches the maximum opening angle, and the longer the braking time is required. Conversely, the slower the door opening speed is, the smaller the kinetic energy is when the door opening angle reaches the maximum opening angle, and the shorter the braking time is required. This is conducive to better braking the door, thereby more accurately offsetting the kinetic energy of the door body continuing to open and eliminating the movement trend of the door body.

[0049] Optionally, the refrigerator determines the braking duration according to the positive correlation between the door opening speed and the refrigeration duration, including: when the door opening speed is in the first speed interval, the refrigerator determines the braking duration to be the first duration value. Or, when the door opening speed is in the second speed interval, the refrigerator determines the braking duration to be the second duration value. Or, when the door opening speed is in the third speed interval, the refrigerator determines the braking duration to be the third duration value. Wherein, the upper limit threshold of the first speed interval is less than the lower limit threshold of the second speed interval, the upper limit threshold of the second speed interval is less than the lower limit threshold of the third speed interval, the first duration value is less than the second duration value, and the second duration value is less than the third duration value.

[0050] In this way, the faster the door opening speed is, the greater the kinetic energy is when the door opening angle reaches the maximum opening angle, and the longer the braking time is required. Conversely, the slower the door opening speed is, the smaller the kinetic energy is when the door opening angle reaches the maximum opening angle, and the shorter the braking time is required. This is conducive to better braking the door, thereby more accurately offsetting the kinetic energy of the door body continuing to open and eliminating the movement trend of the door body.

[0051] Specifically, the value of the first speed interval may be [0, 15° / s), the value of the second speed interval may be [15° / s, 30° / s], and the value of the third speed interval may be (30° / s, +∞). The value of the first duration value may be 0.1s, the value of the second duration value may be 0.2s, and the value of the third duration value may be 0.5s.

[0052] This helps to more accurately determine the braking duration based on the door opening speed.

[0053] Optionally, the door opening speed is determined in the following manner: the refrigerator determines a total door opening angle and a total door opening time during the door opening process. The refrigerator determines the door opening speed according to the total door opening angle and the total door opening time.

[0054] In this way, the door opening speed is determined according to the total door opening angle and the total door opening time during the refrigerator door opening process, so that the door opening speed can better reflect the kinetic energy when the door opening angle reaches the maximum door opening angle, thereby more accurately determining the required braking time. This is conducive to more accurate door braking, thereby more accurately offsetting the kinetic energy of the door body continuing to open and eliminating the movement trend of the door body.

[0055] Optionally, the refrigerator determines the door opening speed according to the total door opening angle and the total door opening time, including: the refrigerator determines the door opening speed, and the door opening speed is the ratio of the total door opening angle to the total door opening time.

[0056] In this way, it is helpful to more accurately determine the door opening speed according to the total door opening angle and the total door opening time during the refrigerator door opening process, so that the door opening speed can better reflect the kinetic energy when the door opening angle reaches the maximum door opening angle, thereby more accurately determining the required braking time. This is conducive to more accurately achieving door braking, thereby more accurately offsetting the kinetic energy of the door body continuing to open and eliminating the movement trend of the door body.

[0057] Optionally, the refrigerator further includes: the refrigerator controls the operation state of the first motor and the second motor according to the switch state of the first door body and the second door body. When the first motor and the second motor are both stopped and the first door body and the second door body are both closed, the refrigerator controls the first clutch and the first transmission mechanism to open and synchronously controls the second clutch and the second transmission mechanism to open, so as to reduce the duration of noise.

[0058] In this way, the operation state of the first motor and the second motor is controlled according to the switch state of the first door body and the second door body, and then when the first motor and the second motor are both stopped and the first door body and the second door body are both closed, the motor does not generate driving force for the door body, and the opening or engagement of the clutch and the transmission mechanism does not affect the switch state of the door body. At this time, the first clutch and the first transmission mechanism are controlled to open and the second clutch and the second transmission mechanism are controlled to open synchronously, which is conducive to reducing the noise time generated by the clutch opening when the refrigerator is closed, and improving the user experience. At the same time, it takes into account the prevention of malfunction caused by the inertia of the door body when the refrigerator is opened, and maintains user safety.

[0059] Optionally, the refrigerator controls the operation state of the first motor and the second motor according to the switch state of the first door and the second door, including: when the first door is closed, the refrigerator controls the first motor to stop. And / or when the second door is closed, the refrigerator controls the second motor to stop.

[0060] In this way, when the door is closed, the corresponding motor is controlled to stop. At this time, the motor does not generate driving force for the door, and the opening or engagement of the clutch and the transmission mechanism does not affect the switch state of the door. At this time, the corresponding clutch and the corresponding transmission mechanism do not need to be opened. After the first motor and the second motor are stopped and the first door and the second door are closed, the first clutch and the first transmission mechanism are controlled to open and the second clutch and the second transmission mechanism are controlled to open synchronously. This is conducive to reducing the noise time generated by the clutch opening when the refrigerator is closed, and improving the user experience.

[0061] Combination Figure 5 As shown, the embodiment of the present disclosure provides another method for opening and closing a refrigerator door, comprising:

[0062] S501, the refrigerator determines the door opening angle in response to the door opening instruction.

[0063] S502, when the door opening angle is greater than or equal to the maximum angle value, the refrigerator controls the clutch and transmission mechanism to maintain the opening braking time to brake the door body.

[0064] S503, the refrigerator controls the operating states of the first motor and the second motor according to the open and close states of the first door body and the second door body.

[0065] S504, when the first door and the second door are both closed, the refrigerator controls the first clutch and the second clutch to open synchronously to reduce the duration of noise.

[0066] By using the refrigerator door opening and closing method provided by the embodiment of the present disclosure, when the door opening angle is greater than or equal to the maximum angle value, the refrigerator reaches the maximum opening angle, but at this time the door body will continue to open to the maximum angle due to inertia. Figure 3-2The angle shown is controlled, and the clutch and transmission mechanism are delayed to open for braking. Thereby, the kinetic energy of the door body continuing to open is offset, the movement tendency of the door body is eliminated, and the door body remains motionless after opening to the maximum angle, thereby preventing malfunction caused by the inertia of the door body, improving the safety of opening and closing the refrigerator door, and maintaining the safety of users. At the same time, the operating state of the first motor and the second motor is controlled according to the switching state of the first door body and the second door body, and then when the first motor and the second motor are both stopped and the first door body and the second door body are both closed, the motor does not generate driving force for the door body, and the opening or engagement of the clutch and the transmission mechanism does not affect the switching state of the door body. At this time, the first clutch and the first transmission mechanism are controlled to open and the second clutch and the second transmission mechanism are synchronously controlled to open, which is conducive to reducing the noise time generated by the clutch opening when the refrigerator is closed, and improving the user experience.

[0067] Combination Figure 6 As shown, the embodiment of the present disclosure provides another method for opening and closing a refrigerator door, comprising:

[0068] S601, the refrigerator determines the door opening angle in response to the door opening instruction.

[0069] S602: When the door opening angle is greater than or equal to the maximum angle value, the refrigerator determines the door opening speed.

[0070] S603, when the door opening speed is in the first speed range, the refrigerator determines that the braking time is the first time value. Or,

[0071] S604: When the door opening speed is in the second speed range, the refrigerator determines that the braking time is the second time value. Or,

[0072] S605, when the door opening speed is in the third speed range, the refrigerator determines that the braking time is a third time value.

[0073] S606, the refrigerator controls the clutch and transmission mechanism to maintain the open braking time to brake the door.

[0074] Among them, the upper limit threshold of the first speed interval is less than the lower limit threshold of the second speed interval, the upper limit threshold of the second speed interval is less than the lower limit threshold of the third speed interval, the first duration value is less than the second duration value, and the second duration value is less than the third duration value.

[0075] By using the refrigerator door opening and closing method provided by the embodiment of the present disclosure, when the door opening angle is greater than or equal to the maximum angle value, the refrigerator reaches the maximum opening angle, but at this time the door body will continue to open to the maximum angle due to inertia. Figure 3-2The clutch and transmission mechanism are controlled to delay opening for braking at the angle shown. The greater the door opening speed, the greater the kinetic energy when the door opening angle reaches the maximum door opening angle, and the longer the required braking time is. Conversely, the smaller the door opening speed, the smaller the kinetic energy when the door opening angle reaches the maximum door opening angle, and the shorter the required braking time is. This is conducive to better braking the door body, thereby more accurately offsetting the kinetic energy of the door body continuing to open, eliminating the movement trend of the door body, and allowing the door body to remain motionless after opening to the maximum angle, preventing malfunctions caused by the inertia of the door body, improving the safety of opening and closing the refrigerator door, and maintaining user safety.

The determination module 701 is configured to determine the door opening angle in response to a door opening instruction. The control module 702 is configured to control the clutch and transmission mechanism to maintain the opening braking time to brake the door body when the door opening angle is greater than or equal to the maximum angle value.

[0077] By using the device 200 for opening and closing a refrigerator door provided by the embodiment of the present disclosure, when the door opening angle is greater than or equal to the maximum angle value, the refrigerator reaches the maximum opening angle, but at this time the door body will continue to open to the maximum angle due to inertia. Figure 3-2 The clutch and transmission mechanism are controlled to open at a delayed time for braking, thereby offsetting the kinetic energy of the door body continuing to open, eliminating the movement trend of the door body, and keeping the door body stationary after opening to the maximum angle, preventing malfunction caused by the inertia of the door body, improving the safety of opening and closing the refrigerator door, and maintaining the safety of users.

[0078] Combination Figure 8 As shown, the embodiment of the present disclosure provides a device 300 for opening and closing a refrigerator door, including a processor 800 and a memory 801. Optionally, the device 300 may also include a communication interface 802 and a bus 803.
