[0007] Preferably, the electromagnet 1 and electromagnet 2 cooperate with two groups of strong magnets to attract and lock the door through the change of magnetic poles and eliminate the bounce-opening of the door.

[0008] Preferably, the electromagnet 1 and the electromagnet 2 are connected to a control panel embedded on the refrigerator door frame.

[0009] After adopting the above structure, the beneficial effects of the utility model are as follows: 1. It adopts the cooperation of magnets and electromagnets to realize magnetic door closing and magnetic door opening structure. The magnetic force generated by the electromagnet is stable, which realizes stable force when closing the refrigerator door, thereby making the sealing more stable.

[0010] 2. The magnets and electromagnets are hidden inside the door body and frame, making the door body more beautiful and intelligent.

[0016] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments illustrated in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0017] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0018] See Figure 1-Figure 3As shown, this specific embodiment adopts the following technical scheme: it includes a refrigerator sealed door 1, a refrigerator door frame 2, an elastic connecting hinge 3, and a magnetic lock assembly 4; the interior of the refrigerator door frame 2 is connected to the refrigerator sealed door 1 through two groups of elastic connecting hinges 3 on one side, and the opening side of the refrigerator sealed door 1 and the refrigerator door frame 2 is provided with a magnetic lock assembly 4; wherein, the magnetic lock assembly 4 is composed of a strong magnet 5, an electromagnet 1 6, and an electromagnet 2 7; two groups of strong magnets 5 are fixed to the inside of the outer edge of the refrigerator sealed door 1, and an electromagnet 1 6 and an electromagnet 2 7 are respectively provided on the refrigerator door frame 2, and the electromagnet 1 6 and the electromagnet 2 7 correspond to the two groups of strong magnets 5.

[0019] The strong magnet 5 is a circular ring structure, with two sets of strong magnets 5 fixed with the same magnetic pole facing downward. The electromagnets 1 and 2, 7, have opposite magnetic poles facing upward, and are interlocked. The strong magnet 5, with its N or S pole facing downward, cooperates with the electromagnets 1 and 2, 7, with different magnetic poles, to attract and lock the door and prevent it from bouncing open.

[0020] In addition, the electromagnet 1 6 and the electromagnet 2 7 are connected to the control panel embedded on the refrigerator door frame 2; the control panel directly controls the on and off of the electromagnet 1 6 and the electromagnet 2 7 to control the closing and bouncing opening of the door.

[0021] This specific embodiment utilizes a combination of magnets and electromagnets to achieve both magnetically closing and magnetically opening the door. The electromagnet generates a stable magnetic force, ensuring consistent closing force and a more reliable seal. Both the magnets and electromagnets are concealed within the door and frame, making the door more aesthetically pleasing and intelligent. Long-term wear and tear of the buckling components prevents this, ensuring stable opening and closing force and a stable seal.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
