Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background Art

[0002] As people's consumption levels rise, traditional single-door, true-cooling refrigerators are gradually disappearing from the market, while a variety of air-cooled refrigerators with sophisticated appearances and diverse functions have entered the mainstream. The application of automatic door opening and closing technology in the refrigerator field is still in its early stages. Generally, a rotating device is installed on the refrigerator door, which directly drives the door to rotate to achieve opening and closing. However, the negative pressure and magnetic attraction between the refrigerator and the door cause the door to shake when it is opened. To solve this problem, the existing technology directly uses the driving mechanism of the rotating device to drive the push rod to a position near the rotating axis of the door. During this process, a large thrust is still required to overcome the negative pressure and the magnetic force of the magnetic attraction structure. When the door is separated from the refrigerator, this thrust still causes the door to rotate rapidly, causing shaking and even damage to the door. Summary of the Invention

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] Refrigerators with automatic door opening and closing devices generally use a rotating mechanism to directly drive the door body to open from the cabinet. In this method, the torque of the rotating mechanism is needed to overcome the locking force of the cabinet on the door body in order to open the door body. However, at the moment the door body opens, the torque of the rotating mechanism is still very large, and the door body will be instantly accelerated and have a very high rotation speed. This situation is the same as the case of manually opening the door, and the door body will still produce a lot of shaking. In order to solve the above problems, the prior art provides a technical solution in which an additional push rod is provided on the rotating mechanism to push the door body near the rotation axis. However, the push rod in this position still requires a large thrust to open the door body. At the moment the door body opens, the large thrust provided by the push rod will still accelerate the door body to a very high rotation speed, and the door body will still produce a large shaking. In other words, it does not solve the problem of large shaking of the door body. Therefore, the present application provides a solution as follows. Figures 1 to 3 The refrigerator shown includes: a cabinet; a door body 1, which is rotatably arranged on the cabinet and can close or open the cabinet; and a pushing device 2, which is located on a side away from the rotation axis of the door body 1 and can push the door body 1 to open the cabinet. That is, in this application, the pushing device 2 is separately arranged so that the pushing device 2 pushes the side of the door body 1 away from the rotation axis, so that the pushing device 2 only needs to provide a force to overcome the locking force of the cabinet on the door body 1 to open the door body 1. In other words, at the moment the door body 1 is opened, the thrust generated by the pushing device 2 will not accelerate the door body 1 to a very high rotation speed, thereby achieving the purpose of reducing the shaking of the door body 1.

[0036] When the user needs to open the door 1, the refrigerator receives the user's opening signal, and the pushing device 2 begins to apply a thrust to the side of the door 1 away from the rotation axis. At this time, the thrust of the pushing device 2 on the door 1 only needs to be greater than the locking force of the cabinet on the door 1. The acceleration effect on the door 1 is much smaller than the acceleration effect of the thrust applied to the rotation axis of the door 1, thereby minimizing the shaking of the door 1. After the pushing device 2 completes the pushing of the door 1, the pushing device 2 can be reset to prepare for the next push of the door 1. At the same time, the reset of the pushing device 2 can prevent the pushing device 2 from protruding and affecting the safety of the user and the appearance of the refrigerator.

[0037] The pushing device 2 includes a push rod 21 movably mounted on the housing; and a push control mechanism 22 mounted on the housing and capable of driving the push rod 21 to freely move. The push control mechanism 22 can receive an opening signal and drive the push rod 21 to move according to the opening signal. The push rod 21 can protrude from the housing and apply a pushing force to the door 1, thereby opening the door 1.

[0038] Preferably, the push rod 21 and the push control mechanism 22 are both arranged on the upper surface of the box body.

[0039] As another embodiment, the pushing device 2 includes: a push rod 21, which is movably provided on the door body 1; and a push control mechanism 22, which is provided on the door body 1 and can drive the push rod 21 to move freely. The push control mechanism 22 can receive an opening signal and drive the push rod 21 to move according to the opening signal, wherein the push rod 21 can protrude from the door body 1 and apply a thrust to the box body, thereby utilizing the reaction force to open the door body 1.

[0040] The push control mechanism 22 includes a first microswitch group, which is arranged corresponding to the push rod 21. During the movement of the push rod 21, the push rod 21 can trigger the first microswitch group. By judging the triggering status of the first microswitch group, it can be determined whether the push rod 21 has reached the set position. When the first microswitch group is triggered, it indicates that the push rod 21 is still in the process of moving and has not reached the set position. The push control mechanism 22 continues to drive the push rod 21 to move until the first microswitch group is de-triggered, that is, the push rod 21 reaches the set position. At this time, the push control mechanism 22 can stop working to maintain the position of the push rod 21 unchanged, or it can drive the push rod 21 to move in the opposite direction to reset it.

[0041] The first microswitch group includes two first microswitches 23. The push rod 21 is provided with two grooves 24. The two first microswitches 23 can move freely between the two grooves 24. When the push rod 21 is not moving, one of the microswitch is in one of the grooves 24, and the other microswitch is triggered by the push rod 21. When the push rod 21 moves, both microswitches are triggered by the push rod 21. When the first microswitches 23 are in the grooves 24, the grooves 24 form a clearance space for the spring of the first microswitches 23, thereby preventing the first microswitches 23 from being triggered. When the first microswitches 23 slide out of the grooves 24, the push rod 21 squeezes the spring of the first microswitches 23, thereby triggering the first microswitches 23.

[0042] Optionally, when the first microswitch 23 is not triggered, the first microswitch 23 is in the off state, and when the first microswitch 23 is triggered, the first microswitch 23 is in the on state. Alternatively, when the first microswitch 23 is not triggered, the first microswitch 23 is in the on state, and when the first microswitch 23 is triggered, the first microswitch 23 is in the off state.

[0043] The refrigerator also includes a control device, which can receive a signal fed back by the first microswitch group. When one first microswitch 23 is in the groove 24 and the other first microswitch 23 is triggered by the push rod 21, the control device receives a feedback signal of "01" from the first microswitch group. At this time, the control device obtains that the push rod 21 is at a preset position. It can also determine that the push rod 21 is in a working preset position for completing the opening of the door body 1 or in an initial preset position based on the last movement state of the push rod 21. When both first microswitches 23 are triggered by the push rod 21, the control device receives a feedback signal of "11" from the first microswitch group. At this time, the control device obtains that the push rod 21 is in the moving process, and the push control mechanism 22 is driving the push rod 21 to move, to push open the door body 1 or to reset it.

[0044] The positions of the two first micro switches 23 can be adjusted, thereby achieving the purpose of adjusting the push rod 21 to different shapes.

[0045] The push rod 21 is provided with a rack 25, and the push control mechanism 22 is provided with a push drive gear, which meshes with the rack 25. Preferably, a reducer or other structure is provided between the push drive gear and the rack 25 to amplify the torque generated by the push control mechanism 22.

[0046] The refrigerator further includes a first control mechanism for detecting the actual resistance encountered during the opening of the door 1. The first control mechanism is disposed on the pushing device 2 and is electrically connected to the pushing device 2. When the actual resistance detected by the first control mechanism is greater than a preset resistance value, it indicates that there is an obstruction at the door 1 (such as a human hand or a wall), and the pushing device 2 cannot continue to push the door 1. In this case, the pushing device 2 stops pushing and / or resets, thereby preventing damage to the pushing device 2 or the door 1.

[0047] Specifically, the first control mechanism can obtain the working current of the push control mechanism 22. When the working current of the push control mechanism 22 is greater than a first preset current value, it indicates that there is an obstruction at the door body 1.

[0048] The refrigerator also includes a rotating device 3, which can drive the door body 1 to open the box body. The rotating device 3 includes: an output shaft 31, which is provided on the door body 1 and can drive the door body 1 to rotate; and a rotation control mechanism 32 is provided on the box body, and the rotation control mechanism can drive the output shaft 31 to rotate. After the pushing device 2 pushes the door body 1 away from the box body, the rotating device 3 can continue to drive the door body 1 to rotate, and finally realize the full opening of the door body 1. Similarly, the rotating device 3 can also drive the door body 1 to rotate in the direction close to the box body, so that the door body 1 gradually closes the box body. Finally, the door body 1 is sealed on the box body under the magnetic attraction of the box body to the door body 1 and the closing action of the closer, completing the process of closing the box body.

[0049] The rotation device 3 further includes a clutch mechanism, through which the rotation control mechanism 32 is transmission-connected to the output shaft 31, and the clutch mechanism is capable of controlling the connection and disconnection between the rotation control mechanism 32 and the output shaft 31. When a user manually rotates the door body 1 or the door body 1 encounters resistance during rotation, the clutch mechanism is capable of disconnecting the output shaft 31 from the rotation control mechanism 32, thereby preventing the rotation control mechanism 32 from continuing to operate and causing damage to the door body 1 and / or the rotation control mechanism 32, thereby preventing the user from using the door.

[0050] The clutch mechanism includes a first clutch mechanism 36 and a second clutch mechanism 37. The rotating device 3 also includes a transmission mechanism 33 for adjusting torque. The rotation control mechanism 32 is connected to the transmission mechanism 33 via the first clutch mechanism 36, and the transmission mechanism 33 is connected to the output shaft 31 via the second clutch mechanism 37. By providing the first clutch mechanism 36 and the second clutch mechanism 37, the disengagement between the rotation control mechanism 32 and the transmission mechanism 33 and the disengagement between the output shaft 31 and the transmission mechanism 33 can be controlled respectively. When the rotation control mechanism 32 is disengaged from the transmission mechanism 33, the rotation control mechanism 32 idles. At this time, the transmission mechanism 33 generates resistance to the movement of the output shaft 31 and the door body 1, thereby causing the door body 1 to remain in the corresponding position. When the output shaft 31 is disengaged from the transmission mechanism 33, the output shaft 31 is only connected to the door body 1. At this time, the rotation process of the door body 1 is not affected by the resistance in the transmission mechanism 33, thereby achieving low-resistance rotation of the door body 1.

[0051] Preferably, the transmission mechanism 33 includes a plurality of gears meshing in sequence, and increases the torque transmitted to the output shaft through different gear ratios.

[0052] The refrigerator further includes a second control mechanism for detecting an operating current of the rotation control mechanism 32. The second control mechanism is disposed on the rotation device 3 and is electrically connected to the first clutch mechanism 36. When the operating current detected by the second control mechanism is greater than a preset value, the rotation control mechanism 32 is in a state where it cannot rotate normally (e.g., if the rotation control mechanism 32 is a motor, the motor is in a stalled state). If it is determined that the door body is blocked by an object and cannot rotate to open or close normally, the second control mechanism activates the first clutch mechanism 36 to disengage the rotation control mechanism 32 from the transmission mechanism 33, allowing the rotation control mechanism 32 to operate normally. At the same time, the door body 1 will not continue to move, thereby preventing damage to the rotation control mechanism 32 and the door body 1.

[0053] The refrigerator further includes a third control mechanism for detecting the actual torque during the rotation of the door body 1. The third control mechanism is disposed on the output shaft 31 and is electrically connected to the second clutch mechanism 37. When the third control mechanism detects that the actual torque during the rotation of the door body 1 is greater than a preset value, indicating that the user is manually opening or closing the door body, the third control mechanism controls the second clutch mechanism 37 to operate, disengaging the output shaft 31 from the transmission mechanism 33. The door body 1 does not need to overcome the resistance on the transmission mechanism 33 during the rotation process. That is, the rotation of the door body 1 at this time is the same as when no rotation device is provided, thereby reducing the force required by the user to rotate the door body 1 and improving the user experience.

[0054] It should be noted that when the door body 1 is not at its maximum opening and remains for a first set time, the rotation control mechanism 32 controls the door body 1 to open to its maximum opening or controls the door body 1 to close the cabinet. When the door body 1 is at its maximum opening and remains for a second set time, the rotation control mechanism 32 controls the door body 1 to close the cabinet. At this time, the refrigerator will determine that the user has forgotten to close the door, and the refrigerator needs to close the door body 1 to the cabinet to ensure normal operation of the refrigerator. The first set time ranges from 10s to 20s, preferably 15s. The second set time ranges from 30s to 120s, preferably 60s.

[0055] The rotation control mechanism 32 includes a second microswitch group, which is arranged corresponding to the output shaft 31. During the rotation of the output shaft 31, the output shaft 31 can trigger the second microswitch group. By judging the triggering status of the second microswitch group, it can be determined whether the output shaft 31 has rotated to the set position. When the second microswitch group is triggered, it indicates that the output shaft 31 is still in the process of rotation and has not reached the set position. The rotation control mechanism 32 continues to drive the door body 1 to rotate until the second microswitch group is deactivated, that is, the output shaft 31 has rotated to the set position. At this time, the rotation control mechanism 32 stops working to maintain the position of the door body 1 unchanged.

[0056] The second microswitch assembly includes two second microswitches 34, which are encircled by the output shaft 31. A mating surface 35 is formed on the output shaft 31. When the output shaft 31 is not rotating, one of the second microswitches 34 is triggered by the output shaft 31, while the other is located at the mating surface 35. During rotation of the output shaft 31, both microswitches are triggered by the output shaft 31. When the second microswitches 34 are located at the mating surface 35, the mating surface 35 creates a clearance for the springs of the second microswitches 34, preventing them from being triggered. However, when the second microswitches 34 slide out of the mating surface 35, the output shaft 31 squeezes the springs of the second microswitches 34, triggering them.

[0057] Optionally, when the second microswitch 34 is not triggered, the second microswitch 34 is in the off state, and when the second microswitch 34 is triggered, the second microswitch 34 is in the on state. Alternatively, when the second microswitch 34 is not triggered, the second microswitch 34 is in the on state, and when the second microswitch 34 is triggered, the second microswitch 34 is in the off state.

[0058] The refrigerator also includes a control device, which can receive a signal fed back by the second microswitch group. When one second microswitch 34 is at the mating surface 35 and the other second microswitch 34 is triggered by the push rod 21, the control device receives a feedback signal of "01" from the second microswitch group. At this time, the control device obtains that the output shaft 31 is at a preset position. It can also determine that the output shaft 31 is at a working preset position for completing the opening of the door body 1 or at an initial preset position based on the last movement state of the output shaft 31. When both second microswitches 34 are triggered by the output shaft 31, the control device receives a feedback signal of "11" from the second microswitch group. At this time, the control device obtains that the output shaft 31 is in the rotation process, and the rotation control mechanism 32 is driving the output shaft 31 to rotate to open the door body 1 or reset it.

[0059] The mating surface 35 on the output shaft 31 is a plane formed by cutting on the output shaft 31 .

[0060] The refrigerator further includes a control device, which is disposed on the door body 1 or the box body, and is capable of obtaining a user's door opening and closing instructions and controlling the pushing device 2 according to the door opening and closing instructions.

[0061] The refrigerator further includes a vibration detection mechanism, which is disposed on the door body 1 and is capable of acquiring vibrations on the door body 1 and sending the vibrations on the door body 1 as the door opening and closing instructions to the control device.

[0062] Preferably, the vibration detection mechanisms are multiple and evenly distributed on the door body to increase the accuracy of detecting door body vibration. The vibration detection mechanisms can be set at the sharp corners of the door body.

[0063] In other embodiments, the refrigerator may also obtain a touch signal for the door body 1 through a touch control mechanism, and use the touch signal as a door opening and closing instruction from the user.

[0064] Optionally, the refrigerator is also provided with an alarm mechanism. When the resistance encountered by the door body 1 during the process of being pushed or rotating is greater than a set value, the alarm mechanism will sound an alarm to remind the user that the door body 1 is obstructed and cannot move.

[0065] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
