[0002] In order to prevent the loss of cold energy in the gap between the two doors, a vertical beam is usually provided on one of the doors. When the door is closed, the vertical beam is extended to cover the gap, and when the door is opened, the vertical beam is retracted, so as not to affect the opening and closing of the refrigerator door. When the refrigerator door is opened, there is a situation where the vertical beam cannot be retracted in time and collides with the refrigerator door on the opposite side. Utility Model Content

[0003] One purpose of the utility model is to provide a side-by-side refrigerator with vertical beams that can be automatically unfolded and retracted.

[0004] Another further object of the utility model is to provide a side-by-side refrigerator that can timely unfold and retract vertical beams.

[0005] In particular, the utility model provides a side-by-side refrigerator. The side-by-side refrigerator comprises:

[0006] Box;

[0007] A first door body is rotatably connected to one side of the box body, and a signal receiver is arranged on the first door body;

[0008] The second door body is rotatably connected to the other side of the box body, the second door body is provided with a signal transmitter, and the signal receiver and the signal transmitter are configured to be arranged opposite to each other when the first door body and the second door body are in a closed state, so that the signal receiver can receive the transmission signal of the signal transmitter to generate a reception signal;

[0009] A vertical beam is rotatably disposed on a side of the first door body close to the second door body, and is configured to seal a gap between the first door body and the second door body when the first door body and the second door body are in a closed state;

[0010] The vertical beam flipping device is connected to the signal receiver and is configured to drive the vertical beam to rotate according to the received signal of the signal receiver.

[0011] Furthermore, the vertical beam flipping device is also configured to: when receiving a receiving signal from the signal receiver, drive the vertical beam to unfold to seal the gap; and when not receiving a receiving signal from the signal receiver, drive the vertical beam to flip toward the first door body to avoid collision between the vertical beam and the second door body.

[0012] Furthermore, the signal transmitter is arranged on the side of the first door body facing the second door body; and the signal receiver is arranged on the side of the second door body facing the first door body, and the arrangement heights of the signal receiver and the signal transmitter are consistent.

[0013] Furthermore, the signal receiver is an infrared signal receiver, and the signal transmitter is an infrared signal transmitter.

[0014] Furthermore, the vertical beam flipping device includes: a motor, which is arranged inside the first door body, connected to the vertical beam, and configured to drive the vertical beam to rotate according to the receiving signal of the signal receiver.

[0015] Furthermore, the length of the vertical beam is the same as the height of the internal space of the box, and when the first door body and the second door body are in the closed state, the upper and lower inner wall areas of the box corresponding to the two ends of the vertical beam are flush, so that the vertical beam can rotate freely.

[0016] Furthermore, the double-door refrigerator also includes: a human body detection sensor, which is arranged on the first door body or the second door body, and is configured so that when the human body detection sensor detects a human body signal, and when the signal receiver receives the transmission signal of the signal transmitter, the vertical beam flipping device drives the vertical beam to flip toward the first door body to avoid the vertical beam from colliding with the second door body; when the human body detection sensor has no induction signal and the signal receiver receives the transmission signal of the signal transmitter, the vertical beam flipping device drives the vertical beam to unfold to seal the gap.

[0017] Furthermore, the first door body is provided with a first handle, and a human body detection sensor is provided inside the first handle.

[0018] Furthermore, the second door body is provided with a second handle, and a human body detection sensor is provided inside the second handle.

[0019] Furthermore, the human body detection sensor is an infrared sensor.

[0020] The double-door refrigerator of the present invention has a signal receiver and a signal transmitter respectively arranged on the first door body and the second door body, so only one set of signal receiver and signal transmitter needs to be installed. The vertical beam can be automatically extended and retracted regardless of opening the first door body or the second door body alone or simultaneously. The vertical beam can be controlled by utilizing a simplified structure, thereby improving the utilization efficiency of the signal element.

[0021] Furthermore, the double-door refrigerator of the utility model can sense the door opening action in advance through the human body detection sensor at the handle, so that there is enough time to retract the vertical beam in time, avoiding the collision of the vertical beam with the refrigerator door on the opposite side due to the untimely retraction of the vertical beam. After closing the door body, the vertical beam is only deployed when there is no signal from the human body detection sensor at the handle, avoiding the ineffective movement of the vertical beam when the user closes the door body and immediately opens the door body. By combining the signal changes of the two positions of the human body detection sensor at the handle and the signal receiver on the first door body, the state of the door body can be accurately judged, and the vertical beam can be retracted in time and deployed in time.

[0034] Figure 1 1 is an overall schematic diagram of a side-by-side refrigerator 100 according to an embodiment of the present invention, and the side-by-side refrigerator 100 may generally include: a cabinet 101 and two doors 110, 120. The cabinet 101 defines a storage compartment, which may be a refrigeration compartment, a freezing compartment, or a variable temperature compartment.

[0035] In some embodiments, the two door bodies are respectively a first door body 110 and a second door body 120, the first door body 110 is rotatably connected to one side of the box body 101, and the second door body 120 is rotatably connected to the other side of the box body 101. That is, the first door body 110 and the second door body 120 form a double-door structure. The first door body 110 and the second door body 120 can be used as door bodies of a refrigerated compartment.

[0036] like Figure 1As shown, the pivot end of the first door 110 can be rotatably mounted on the front left end of the box body 101 around a vertical axis, and the pivot end of the second door 120 can be rotatably mounted on the front right end of the box body 101 around a vertical axis. When the two doors are closed, there is a gap between the first door 110 and the second door 120. If no sealing measures are taken for the gap, the cold air inside the refrigerator will leak from the gap to the outside of the refrigerator, thereby affecting the refrigeration or freezing effect of the refrigerator.

[0037] Figure 2 This is a schematic diagram of a side-by-side refrigerator 100 according to an embodiment of the utility model, in which the side-by-side door portion of the refrigerator is hidden from the second door body 120. In order to seal the gap between the first door body 110 and the second door body 120 in the closed state to prevent cold leakage, the refrigerator is specially provided with a vertical beam 113. The vertical beam 113 is rotatably arranged on the inner side of the first door body 110 (i.e., the side facing the storage compartment when the door is closed) and close to the side of the second door body 120. The vertical beam 113 extends to the upper and lower wall surfaces inside the box body 101 in the vertical direction. The length of the vertical beam 113 is the same as the height of the internal space of the box body 101. When the first door body 110 and the second door body 120 are in the closed state, the upper and lower inner wall surface areas of the box body 101 corresponding to the two ends of the vertical beam 113 are flush, so that the vertical beam 113 can rotate freely. The vertical beam 113 is rotatably connected to the first door body 110 via a rotating connection mechanism, so that the vertical beam 113 can rotate along the vertical axis inside the first door body 110 to rotate between the stowed position and the deployed position.

[0038] Figure 3 It is a top view schematic diagram of the first door body 110 of the side-by-side refrigerator 100 in an open state according to an embodiment of the utility model. In some embodiments, when the vertical beam 113 is in a retracted state (the vertical beam 113 does not play a sealing role), the sealing surface of the vertical beam 113 and the second door body 120 can be in a vertical state with the inner wall surface of the first door body 110 or the second door body 120. The sealing surface of the vertical beam 113 refers to the surface where the vertical beam 113 and the first door body 110 and the second door body 120 are respectively attached to each other for sealing, and the inner wall surface of the first door body 110 or the second door body 120 refers to the wall surface of the first door body 110 or the second door body 120 facing the storage compartment when the door is closed. Figure 4 It is a top view schematic diagram of a double-door refrigerator 100 in which the first door body 110 and the second door body 120 are both in a closed state according to an embodiment of the utility model. When the vertical beam 113 of the second door body 120 is in an expanded state, the sealing surfaces of the second door body 120 and the vertical beam 113 are respectively in contact with the first door body 110 and the second door body 120, and the sealing surface of the vertical beam 113 is parallel to the inner wall surface of the first door body 110 or the second door body 120 to seal the gap.

[0039] In other embodiments, when the vertical beam 113 is in a retracted state, the sealing surface of the vertical beam 113 and the inner wall surface of the first door body 110 or the second door body 120 may not be perpendicular, and may be at any angle at which the vertical beam does not collide with the opposite door body.

[0040] Figure 5 This is a schematic diagram of a side-by-side refrigerator 100 in which a first door body 110 and a second door body 120 are both in an open state according to an embodiment of the utility model. In some embodiments, a signal receiver 115 is provided on the first door body 110, and a signal transmitter 121 is provided on the second door body 120. The signal receiver 115 and the signal transmitter 121 are arranged relative to each other when the first door body 110 and the second door body 120 are in a closed state, so that the signal receiver 115 can receive the transmission signal of the signal transmitter 121 to generate a receiving signal.

[0041] In other embodiments, the first door body 110 may be provided with a signal transmitter 121, and the second door body 120 may be provided with a signal receiver 115, and the signal transmitter 121 and the signal receiver 115 are arranged relative to each other when the first door body 110 and the second door body 120 are in a closed state, so that the signal receiver 115 can receive the transmission signal of the signal transmitter 121 to generate a receiving signal.

[0042] In some embodiments, the signal transmitter 121 can be arranged on the side of the first door body 110 facing the second door body 120, and the signal receiver 115 can be arranged on the side of the second door body 120 facing the first door body 110, and the arrangement height of the signal receiver 115 and the signal transmitter 121 are consistent. For example, the signal receiver 115 and the signal transmitter 121 can be arranged on the upper frame of the first door body 110 and the second door body 120, or the signal receiver 115 and the signal transmitter 121 can be arranged on the lower frame of the first door body 110 and the second door body 120, or they can be arranged at any position on the side of the first door body 110 and the second door body 120 respectively.

[0043] In some embodiments, the signal receiver 115 may be an infrared signal receiver, and the signal transmitter 121 may be an infrared signal transmitter. Infrared sensors have very strong noise immunity, low power consumption, and are not affected by corrosion or oxidation.

[0044] In other embodiments, the signal receiver 115 and the signal transmitter 121 may also use Hall devices. For example, a Hall sensor is used as the signal receiver 115 in this embodiment to sense the magnetic signal of the signal transmitter 121 (magnetic element).

[0045] In some embodiments, multiple rotating connection mechanisms can be set between the first door body 110 and the vertical beam 113, and spaced apart along the length direction of the vertical beam 113 to ensure that the vertical beam 113 can be smoothly flipped from the extended state to the retracted state under the drive of the vertical beam flipping device 114.

[0046] Figure 6 1 is a schematic diagram of the connection relationship between the vertical beam and the vertical beam flipping device 114 of the side-by-side refrigerator 100 according to an embodiment of the utility model. The vertical beam 113 is further provided with the vertical beam flipping device 114 on the first door body 110 or the second door body 120. The vertical beam flipping device 114 includes a motor 116. The motor 116 is arranged inside the first door body 110 and connected to the vertical beam 113. The vertical beam flipping device 114 is connected to the signal receiver 115 by signal, and drives the vertical beam 113 to rotate according to the received signal of the signal receiver 115.

[0047] In some embodiments, the vertical beam flipping device 114 is located between the first door body 110 provided with the vertical beam 113 and the vertical beam 113. The vertical beam flipping device 114 can drive the vertical beam 113 to flip from an extended state to a retracted state. At this time, even if the second door body 120 without the vertical beam 113 is closed first, in the subsequent process of closing the first door body 110, since the vertical beam 113 is already in the retracted state, the vertical beam 113 will not interfere with the second door body 120. The first door body 110 can be closed smoothly, avoiding the hidden danger of collision and damage between the vertical beam 113 and the second door body 120.

[0048] The movement of the vertical beam 113 is driven by the vertical beam flipping device 114, so there is no need to set a guide groove. Since the restriction of the vertical beam 113 guide groove on the movement of the vertical beam 113 is released, the opening and closing of the first door body 110 and the second door body 120 are made consistent, and the door opening and closing is smoother, which improves the user's door opening and closing experience of the second door body 120. In addition, since there is no need to set a recessed guide groove on the refrigerator liner, the inner wall surface of the box body 101 is more flush, thereby optimizing the appearance of the vertical beam 113 and the liner.

[0049] In some embodiments, upon receiving a receiving signal from the signal receiver 115, the vertical beam flipping device 114 drives the vertical beam 113 to unfold to seal the gap. That is to say, when the first door body 110 and the second door body 120 are both closed, the signal receiver 115 and the signal transmitter 121 respectively installed on the first door body 110 and the second door body 120 are in a facing state. At this time, the signal receiver 115 can receive the signal from the signal transmitter 121 and generate a receiving signal, and then the signal receiver 115 transmits the receiving signal to the vertical beam flipping device 114. The vertical beam flipping device 114 drives the vertical beam 113 to unfold, so that the sealing surface of the vertical beam 113 is respectively attached to the inner wall surface of the first door body 110 and the second door body 120 to seal the gap and prevent cold air leakage.

[0050] In the case where the receiving signal from the signal receiver 115 is not received, the vertical beam flipping device 114 drives the vertical beam 113 to flip toward the first door body 110 to avoid the vertical beam 113 from colliding with the second door body 120. That is to say, when either the first door body 110 or the second door body 120 is opened or both the first door body 110 and the second door body 120 are opened, the positional relationship between the signal receiver 115 and the signal transmitter 121 respectively installed on the first door body 110 and the second door body 120 is not directly opposite. At this time, the signal receiver 115 does not receive the signal from the signal transmitter 121, and the vertical beam flipping device 114 drives the vertical beam 113 to flip and retract to the rear side of the first door body 110 to avoid the vertical beam 113 from colliding with the second door body 120 when the first door body 110 is opened.

[0051] In some embodiments, a human body detection sensor 112 may also be provided on the first door body 110 or the second door body 120 of the side-by-side refrigerator 100. When the human body detection sensor 112 detects a human body signal and the signal receiver 115 receives a transmission signal from the signal transmitter 121, the vertical beam flipping device 114 drives the vertical beam 113 to flip toward the first door body 110 to avoid the vertical beam 113 from colliding with the second door body 120. When the human body detection sensor 112 has no sensing signal and the signal receiver 115 receives a transmission signal from the signal transmitter 121, the vertical beam flipping device 114 drives the vertical beam 113 to unfold to seal the gap.

[0052] In the above embodiment, the retraction and deployment of the vertical beam 113 are jointly determined by the signals at two positions, the sensing signal of the human detection sensor 112 and the sensing signal of the signal receiver 115, and the signals at the two positions are comprehensively considered. When the signal receiver 115 has a sensing signal (when both the first door body 110 and the second door body 120 are closed), when the human detection sensor 112 has a sensing signal, the vertical beam 113 is retracted; when the human detection sensor 112 has no sensing signal, the vertical beam 113 is deployed to seal the gap.

[0053] In some embodiments, the first door body 110 may be provided with a first handle 111, and the human detection sensor 112 may be provided inside the first handle 111. When the user needs to open the first door body 110 of the refrigerator, and the user's hand is within a certain range from the first handle 111, the human detection sensor 112 generates a sensing signal, and at the same time, the first door body 110 and the second door body 120 are both in a closed state, and at this time, the signal receiver 115 has a sensing signal. When both the human detection sensor 112 and the signal receiver 115 have sensing signals, the vertical beam flipping device 114 drives the vertical beam 113 to retract, and after the vertical beam 113 is retracted to the rear side of the first door body 110, the user pulls to open the first door body 110.

[0054] In this embodiment, the signals of the sensing signal of the human body detection sensor 112 and the sensing signal of the signal receiver 115 are judged at the same time, so that the vertical beam 113 is driven by the vertical beam flipping device 114 to make a retraction or expansion action, which can avoid the situation that the vertical beam 113 is not retracted in time and causes the vertical beam 113 to collide with the opposite door body. The traditional vertical beam 113 control scheme is to set only one sensor at the door body, only detect the opening change of the door body, and drive the retraction or expansion of the vertical beam 113 through the signal of the change of the door body opening. However, the moment when the door body signal changes often occurs at the same time as the action of opening the door, that is, when the user opens the door body, the sensor set at the door body generates a signal change, and the vertical beam 113 responds. However, due to the limited movement speed of the vertical beam 113, if the door opening speed is too fast, it is very likely that the vertical beam 113 will not be retracted in time, causing the vertical beam 113 to collide with the opposite door body.

[0055] In this embodiment, the signal changes of the sensing signal of the human detection sensor 112 and the sensing signal of the signal receiver 115 are determined at the same time. Since the retraction or expansion of the vertical beam 113 is mainly caused by the change of the sensing signal at the human detection sensor 112, the user can decompose two action processes in the process of opening the refrigerator door. The user first needs to touch the first handle 111 on the first door body 110 with his hand. After the user holds the first handle 111, he pulls the first door body 110. In other words, the detection of the sensing signal at the human detection sensor 112 is before the door opening action. Before the user makes the door opening action, it is predicted in advance that the user is about to pull the door body. At this time, the sensing signal at the human detection sensor 112 is transmitted to the vertical beam flipping device 114 to drive the vertical beam 113 to retract, and then the user pulls the door body. Before the user pulls the door body, the vertical beam 113 has completed the entire action of retracting the vertical beam 113, completely eliminating the risk of collision caused by the untimely retraction of the vertical beam 113.

[0056] The state change of the human detection sensor 112 from sensing the presence of a signal to not sensing a signal can be defined as: 1→0, and vice versa as 0→1. The state change of the signal receiver 115 from sensing the presence of a signal to not sensing a signal can be defined as: 1→0, and vice versa as 0→1. The closed state of the refrigerator is the initial state. When the human detection sensor 112 (0→1) and the signal receiver 115 (1→1), the user is ready to open the door, and the vertical beam is in a rotating and retracted state; when the human detection sensor 112 (0→1) and the signal receiver 115 (1→1)→(1→0), the door is opened; the vertical beam remains in a retracted state; when the human detection sensor 112 (1→0) and the signal receiver 115 (1→0), the door is opened, and the vertical beam remains in a retracted state; when the human detection sensor 112 (0→1) and the signal receiver 115 (0→1), the door is ready to be closed, and the vertical beam The beam remains retracted (the door may be opened again at any time, so the vertical beam remains motionless at this time); the human body detection sensor 112 (1→0) and the signal receiver 115 (1→1), the door remains closed, and the vertical beam rotates and unfolds; the human body detection sensor 112 (0→1) and the signal receiver 115 (1→1) → (1→0) → (0→1) and the human body detection sensor 112 (1→0) and the signal receiver 115 (1→1), prepare to open the door, and the vertical beam retracts; after opening the door, take the things, and then close the door, and the vertical beam rotates to unfold.

[0057] In addition, by comprehensively considering the signal changes of the two positions of the sensing signal of the human detection sensor 112 and the sensing signal of the signal receiver 115, the vertical beam 113 can be retracted in time after the first door body 110 is closed, thereby avoiding the invalid action of the vertical beam 113. In real life, when many users use a double-door refrigerator, there is a situation where they open the door body, take out the items they want to take, close the door body, and then immediately open the door body. In the case that the traditional vertical beam 113 control scheme is only provided with a sensor at one place of the door body, the vertical beam 113 will make an invalid action of unfolding and then immediately retracting. Moreover, if the movement speed of the vertical beam 113 is slow, there is a risk that the vertical beam 113 hits the door body.

[0058] In the present embodiment, when the above situation occurs, since the user has been touching the first handle 111 with his hand, even if the first door body 110 is closed, the vertical beam 113 still maintains a retracted state. Only when the user's hand leaves the human body detection sensor 112 on the first handle 111 within a certain distance range, and the first door body 110 and the second door body 120 are both in a closed state, the vertical beam 113 will be deployed. Therefore, the present embodiment avoids the vertical beam 113 from making invalid movements in the above situation, and avoids the risk of the vertical beam 113 being deployed in a short period of time and not retracted in time and colliding with the second door body 120.

[0059] In this embodiment, the human body detection sensor 112 is only provided on the first handle 111 on the first door body 110, and the vertical beam 113 and the human body detection sensor 112 are both provided on the first door body 110, that is, the vertical beam 113 is retracted only when the first door body 110 is opened, and the vertical beam 113 is not retracted when the second door body 120 is opened. Moreover, since the positional relationship between the signal receiver 115 and the signal transmitter 121 respectively installed on the first door body 110 and the second door body 120 is not directly opposite when the first door body 110 is opened, the signal receiver 115 does not receive the signal of the signal transmitter 121 at this time. Therefore, no matter how the signal state of the human body detection sensor 112 changes, that is, whether the user's hand leaves the first handle 111, the vertical beam 113 on the first door body 110 does not rotate and remains in a retracted state.

[0060] In other embodiments, the human body detection sensor 112 may also be disposed in an area on the first door body 110 corresponding to the first handle 111. The second door body 120 may also be provided with a second handle 122, and the human body detection sensor 112 is disposed inside the second handle 122.

[0061] In some embodiments, the human body detection sensor 112 may be an infrared sensor. The infrared sensor may be a passive infrared sensor, which works by detecting infrared rays emitted by the human body. The passive infrared sensor is aimed at detecting human body radiation, is very sensitive to infrared radiation, and can be used for detecting human bodies.

[0062] In some embodiments, the first angle measuring device is connected to the vertical beam flipping device 114 by signal, and is configured to measure the first angle of the first door body 110 relative to the closed state of the first door body 110 and generate a first angle signal; the second angle measuring device is connected to the vertical beam flipping device 114 by signal, and is configured to measure the second angle of the second door body 120 relative to the closed state of the second door body 120 and generate a second angle signal. The vertical beam flipping device 114 drives the vertical beam 113 to rotate according to the control signal.

[0063] During the closing process of the first door body 110 and the second door body 120, when the first angle is greater than the second angle and the second angle is less than the angle threshold, the vertical beam flipping device 114 drives the vertical beam 113 to retract to prevent the vertical beam 113 from colliding with the second door body 120 that is closed first. During the closing process of the first door body 110 and the second door body 120, when the first angle is greater than the second angle and the second angle exceeds the angle threshold, the warning device issues a vertical beam 113 collision warning message. The collision warning message can be conveyed to the user in the form of vibration, sound or light.
