Description

Technical Field

[0001] The utility model belongs to the technical field related to refrigerator door opening, in particular to a refrigerator. Background Art

[0002] In order to achieve the visual effect of no handles and the door body flush with the cabinet door, existing refrigerators generally use push switches. The pressure sensor generates a corresponding pressure change value by sensing the relative displacement of the cabinet and the door body. The pressure change value is compared with the threshold of the trigger switch to determine whether the refrigerator door is open. The corresponding motor module responds according to the judgment signal and drives the mechanical movement of the door body to realize the opening action of the door body.

[0003] It can be understood that the above design can hide the door handle. The user does not need to use the external door handle. He presses the door body with a certain force. The deformation of the door body and the box body produces a pressure change value that is greater than the judgment threshold of opening the door. The motor drives the door body to open. After the door body is opened, there is a gap between the door body and the box body. The user can rotate the door body to the required opening and closing angle and position. However, due to the door opening method, the refrigerator with the above door opening method has the following disadvantages when opening the door: First, after the door body is pushed open by the motor, the user puts his hand into the gap between the door body and the box body to pull the door to the required opening and closing degree. The gap between the door bodies is small, and the user is easy to pinch his hand during use. Secondly, when the user opens the door body, the position of pressing the refrigerator is uncertain. If the user's pressing point is far away from the pressing push rod, since the door body is not absolutely rigid, the pressure change value generated by the pressing position will decay with the deformation of the door body, so that the pressure sensor detects a small value, which is not enough to reach the judgment threshold, resulting in failure to open the door. Finally, since the pressing direction is opposite to the direction in which the door opens, that is, the user presses the door towards the box, while the door opens away from the box, which is not ergonomic. When the user presses with greater force or for a longer period of time, the pressure on the door by the user is greater than the door-opening force of the motor, which will also lead to door opening failure. Utility Model Content

[0004] In view of this, it is necessary to provide a refrigerator for solving the above technical problems.

[0005] A refrigerator, comprising:

[0006] The refrigerator body comprises a box body and a door body, wherein the door body is rotatably mounted on the box body and used to control the opening / closing of the box body, wherein a concave cavity is formed on the door body;

[0007] a handle assembly, mounted on the door body, the handle assembly comprising a flip plate and a trigger member, the flip plate being arranged in the area where the cavity is located and being rotatably connected to the door body, the trigger member being capable of being triggered and generating a first feedback signal, the first feedback signal being used to control the rotation of the flip plate, and the flip plate after rotation being available for grasping by a hand inserted into the cavity;

[0008] A top door assembly is installed on the box body, and the top door assembly can push up the door body under the control of the first feedback signal, so that the door body can be opened from the box body.

[0009] It can be understood that, through the above-mentioned structural setting, the user can grab the rotated flip plate by hand and open the door. In this process, the pulling direction when the user pulls the door body is consistent with the pushing direction when the door assembly pushes the door body, and they are used together to open the door. This not only conforms to the user's ergonomics and operating habits, but also saves effort during the door opening process and avoids the occurrence of hand pinching.

[0010] In one embodiment, the trigger member is installed in the flip cover.

[0011] It is understandable that the trigger is integrated into the flip cover so that the area of ​​the trigger is smaller, thereby preventing the user from accidentally touching the trigger.

[0012] In one embodiment, the trigger member is configured as a pressure sensor.

[0013] It can be understood that, by utilizing the structural characteristics of the pressure sensor, the user can trigger the trigger member by pressing the trigger member, which makes it easier for the user to trigger the trigger member.

[0014] In one embodiment, the handle assembly further includes a rotary drive member, which is transmission-connected to the flip plate and electrically connected to the trigger member, and the rotary drive member can control the rotation of the flip plate on the door body according to the first feedback signal.

[0015] It can be understood that the rotation of the flip plate on the door body is controlled by a rotary drive member, so that the rotation control of the flip plate can be automated to facilitate the user to open the door of the refrigerator.

[0016] In one embodiment, a rotating shaft is formed on the flip plate, the rotating shaft is rotatably mounted on the door body and is drivingly connected to the rotating drive member, and the rotating shaft can rotate relative to the door body under the drive of the rotating drive member to rotate the flip plate.

[0017] In one of the embodiments, the handle assembly further includes a detection sensor, which is capable of detecting a rotation angle of the flip plate and generating a second feedback signal, and the second feedback signal is used to control a rotation speed of the flip plate.

[0018] It is understandable that the rotation angle of the flip plate is detected by the detection sensor to control the rotation speed of the flip plate, which can avoid pinching the hand due to the flip plate rotating too fast.

[0019] In one of the embodiments, the detection sensor is configured as a displacement sensor, and the displacement sensor is installed on the flip plate.

[0020] In one of the embodiments, an end surface of the flip cover away from the box body can be arranged on the same plane as the outer end surface of the door body.

[0021] It can be understood that, through the above-mentioned structural setting, the flip cover is flush with the outer end surface of the door body when it is not flipped up from the door body, so that the flip cover can be hidden when assembled on the door body, which has the effect of improving the overall external aesthetics of the door body.

[0022] In one of the embodiments, the rotation direction of the flip cover when rotating on the door body is consistent with the rotation direction of the door body when rotating on the box body.

[0023] It can be understood that, through the above-mentioned structural arrangement, the rotation direction of the flip cover can be made to conform to the ergonomic design.

[0024] In one embodiment, when the trigger member is not triggered, the flip cover plate is loosely matched with the cavity wall of the concave cavity.

[0025] It can be understood that, through the above-mentioned structural arrangement, the concealment of the flap plate when assembled on the door body can be ensured.

[0026] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0027] The refrigerator for which protection is sought in the present application allows the user to manually grab the rotated flap plate and open the door. During this process, the pulling direction when the user pulls the door body is consistent with the pushing direction when the top door assembly pushes the door body, and both are used together to open the door. This not only conforms to the user's ergonomics and operating habits, but also saves effort during the door opening process and avoids the occurrence of hand pinching.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] The refrigerator 100 for which protection is sought in the present application specifically refers to a refrigerator with an automatic door opening function.

[0038] like Figures 1 to 3 As shown, a refrigerator 100 provided in an embodiment of the present application includes a refrigerator body 10, a handle assembly 20 and a top door assembly (not shown), the refrigerator body 10 includes a cabinet body and a door body 11, the door body 11 is rotatably mounted on the cabinet body, and is used to control the opening / closing of the cabinet body, wherein a concave cavity 111 is provided on the door body 11; the handle assembly 20 is mounted on the door body 11, the handle assembly 20 includes a flip plate 21 and a trigger member 22, the flip plate 21 is arranged in the area where the concave cavity 111 is located and is rotatably connected to the door body 11, the trigger member 22 can be triggered and generate a first feedback signal, the first feedback signal is used to control the rotation of the flip plate 21, and the rotated flip plate 21 can be provided for grabbing by a hand inserted into the concave cavity 111; the top door assembly is mounted on the cabinet body, and the top door assembly can push the top door body 11 under the control of the first feedback signal, and open the door body 11 from the cabinet body. That is, when the triggering member 22 of the refrigerator 100 is triggered, the flip plate 21 can be controlled to rotate on the door body 11 to be grasped by a human hand, and the flip plate 21 can be controlled to start the top door assembly and to be driven to pop off the door body 11 from the inner liner of the box body. Here, the flip plate 21 is configured as a handle for a human hand to grasp.

[0039] It can be understood that when the user operates the refrigerator 100 to open the door automatically, the user can first trigger the trigger member 22 on the handle assembly 20 by hand, and then grab the rotated flip cover 21 by hand to open the door. In this process, the pulling direction when the user pulls the door body 11 is consistent with the pushing direction when the top door assembly pushes the door body 11, and they are used together to open the door. This not only conforms to ergonomics and user operating habits, but also saves effort during the door opening process and avoids the occurrence of hand pinching.

[0040] It should be noted that, when the door body 11 is the door body of the refrigerator compartment, the flap plate 21 can be arranged in the middle position of the door body 11 in the height direction. When the door body 11 is the door body of the freezer compartment, the flap plate 21 can be arranged on the side of the door body 11 close to the refrigerator compartment. This is more ergonomic and facilitates the user to grab the flap plate 21.

[0041] like Figure 3As shown, the trigger member 22 is installed in the flip plate 21. That is to say, the present application integrates the trigger member 22 into the flip plate 21, so that the area of ​​the trigger member 22 is small, which can prevent the user from accidentally touching it. It should be noted that since the flip plate 21 of the present application is used as a handle for human hands to grasp, the overall size of the flip plate 21 is not large, and the trigger member 22 is integrated into the flip plate 21, so that the overall area of ​​the trigger member 22 is small. Here, the trigger member 22 is configured as a pressure sensor 221, and a button is provided on the pressure sensor 221. The pressure sensor 221 can be triggered by driving the pressure sensor 221 after the button is pressed, so that the user can trigger the trigger member 22 by pressing the button, which is convenient for the user to trigger the trigger member 22. It should be noted that the pressure sensor 221 has a pressure threshold. When the pressure value received by the pressure sensor 221 exceeds the pressure threshold, the pressure sensor 221 can be triggered and generate a first feedback signal. Otherwise, the pressure sensor 221 will not be triggered. Of course, in other embodiments, the trigger member 22 can also be triggered by touch, which will not be elaborated here.

[0042] like Figure 3 As shown, the end surface 211 of the flip cover 21 away from the inner shell of the box body can be arranged on the same plane as the outer end surface 112 of the door body 11. In other words, when the flip cover 21 is not flipped up from the door body 11, it is flush with the outer end surface 112 of the door body 11, so that the flip cover 21 can be concealed when assembled on the door body 11, which has the effect of improving the overall appearance of the door body 11.

[0043] Preferably, the rotation direction of the flip plate 21 when rotating on the door body 11 is consistent with the rotation direction of the door body 11 when rotating on the box body, so that the rotation direction of the flip plate 21 can be ergonomically designed to facilitate the user to open the door. Of course, in other embodiments, the rotation direction of the flip plate 21 when rotating on the door body 11 may also be inconsistent with the rotation direction of the door body 11 when rotating on the box body, which will not be elaborated here.

[0044] like Figure 3 As shown, when the trigger member 22 is not triggered, the flip cover 21 is loosely matched with the cavity wall 1111 of the cavity 111. In other words, the cavity 111 and the flip cover 21 are configured in a contoured manner, which ensures the concealment of the flip cover 21 when assembled on the door body 11.

[0045] In the present application, the handle assembly 20 further includes a rotary drive member (not shown), which is transmission-connected to the flip plate 21 and electrically connected to the trigger member 22, and the rotary drive member can control the rotation of the flip plate 21 on the door body 11 according to the first feedback signal. In this way, the structural characteristics of the rotary drive member can be used to realize the automation of the rotation control of the flip plate 21, so that the user can open the door of the refrigerator 100. Here, the rotary drive member is configured as a rotary motor, or other electronic device that can rotate autonomously after being powered on.

[0046] The flip plate 21 is provided with a rotating shaft (not shown), which is rotatably mounted on the door body 11 and is in transmission connection with the rotating drive member, and the rotating shaft can be driven by the rotating drive member to rotate relative to the door body 11 and rotate the flip plate 21. Here, the rotating shaft is arranged on one side of the flip plate 21 in the width direction.

[0047] Preferably, the handle assembly 20 further includes a detection sensor (not shown), which can detect the rotation angle of the flip plate 21 and generate a second feedback signal, and the second feedback signal is used to control the rotation speed of the flip plate 21, so as to avoid pinching the hand due to the excessive rotation speed of the flip plate 21. Here, the detection sensor is configured as a displacement sensor, and the displacement sensor is installed on the flip plate 21. Of course, in other embodiments, the detection sensor can also be configured as an angle sensor, and the angle sensor is used to directly detect the rotation angle of the flip plate 21 when it rotates.

[0048] like Figure 4 As shown, when the refrigerator 100 needs to open the door automatically, the user can first press the trigger member 22, and use the first feedback signal generated when the trigger member 22 is working to control the rotation of the flip plate 21 on the door body 11. At the same time, the top door assembly can push the door body 11 and make the door body 11 bounce off the inner shell of the box body; thereafter, a person's hand can reach into the concave cavity 111 and grab the rotated flip plate 21, so that the subsequent user can pull the door body 11 away from the inner shell of the box body; in this process, since the pulling direction when the user pulls the door body 11 is consistent with the pushing direction when the top door assembly pushes the door body 11, and they are used together to open the door, this not only conforms to ergonomics and the user's operating habits, but also saves effort during the door opening process and avoids the occurrence of hand pinching.

[0049] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection required by the present invention.
