[0002] Currently, most folding door dishwashers on the market use hook locking, employing a mechanical structure to interlock and close the dishwasher door, and must have a mechanical unlocking button. For example, Chinese utility model patent CN217310186U discloses a dishwasher with a double-door structure, where the door is locked and closed using a mechanical mechanism. The door and dishwasher hook locking requires precise dimensional matching and carries the risk of hook misalignment after locking.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a magnetic door opening and closing structure for a dishwasher and a dishwasher.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A magnetic door opening and closing structure for a dishwasher includes a cabinet, a first door, and an electromagnet device. The first door is rotatably connected to the cabinet via a first hinge. A first limiting part is installed on the side of the first door facing the cabinet. The electromagnet device is installed on the cabinet.

[0007] The installation position of the electromagnet device is adapted to the position of the first limiting part. When the first door is closed, the position of the first limiting part is opposite to the electromagnet device, and the electromagnet device can magnetically attract the first limiting part.

[0008] It also includes a second door, which is located above the first door and is rotatably connected to the box via a second hinge. The first and second doors are used together to close the box opening.

[0009] The present invention is further configured such that the second door body is located on the upper side of the first door body, and the first hinge and the second hinge are rotated and linked by a linkage component, so that the first door body and the second door body can open and close synchronously.

[0010] The present invention is further configured such that a second limiting part is installed on the side of the second door facing the box body, and a magnetic block is installed on the box body. When the second door is closed, the position of the second limiting part is opposite to the magnetic block, and the magnetic block can magnetically attract the second limiting part.

[0011] The present invention is further configured such that the magnetic block is a permanent magnet or an electromagnet.

[0012] The present invention is further configured such that the electromagnet device is a traction electromagnet with a retractable iron core.

[0013] The present invention is further configured such that a spring is installed between the end of the iron core and the electromagnet device, the spring abutting against the end of the iron core and acting elastically towards the first limiting part.

[0014] The present invention is further configured such that when the electromagnet device is turned on, it generates magnetism, and the end of the iron core is magnetically attracted to the first limiting part, and the retraction of the iron core drives the first door to close.

[0015] The present invention is further configured such that when the electromagnet device is disconnected and its magnetism is eliminated, the spring elastically pushes the iron core toward the first door body, and the first door body opens.

[0016] The present invention is further configured such that the first limiting part is a permanent magnet, and the first limiting part can actively magnetically attract the iron core.

[0017] This embodiment discloses a dishwasher, including the magnetic door opening and closing structure of the dishwasher as described above. The magnetic structure is used for closing, which can reduce the mechanical components in the dishwasher and simplify the structure of the dishwasher.

[0018] In summary, this utility model has the following beneficial effects:

[0019] The dishwasher door is closed and locked using a magnetic structure. The magnetic attraction eliminates the need for mechanical latches and buttons, making the structure simpler and the method more stable.

[0020] The door is secured by an electromagnet, which has a retractable iron core. When the electromagnet is turned on, it generates magnetism, and the end of the iron core magnetically attracts the first limiting part. When the iron core retracts, it pulls the first door closed, creating a traction action in the closing direction. By controlling the on and off of the magnet, the opening and closing of the first door can be achieved, enabling the dishwasher to open and close automatically. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This embodiment discloses a magnetic door opening and closing structure for a dishwasher, referring to... Figures 1-4 As shown, it includes a box body 1, a first door body 2 and an electromagnet device 6. The first door body 2 is rotatably connected to the box body 1 through a first hinge 4, and the first door body 2 opens and closes by rotating.

[0029] A first limiting part 21 is installed on the side of the first door 2 facing the box 1. The first limiting part 21 can be magnetically attracted.

[0030] The electromagnet device 6 is installed on the housing 1. When the first door 2 is closed, the position of the first limiting part 21 is opposite to the electromagnet device 6. The electromagnet device 6 can attract the first limiting part 21, thereby magnetically attracting and locking the first door 2.

[0031] Furthermore, the dishwasher in this embodiment is a double-door dishwasher, also including a second door 3. The second door 3 is rotatably connected to the cabinet 1 via a second hinge 5. The first door 2 and the second door 3 are used together to close the opening of the cabinet 1. The second door 3 is located above the first door 2. The first hinge 4 and the second hinge 5 are rotatably linked by a linkage, allowing the first door 2 and the second door 3 to open and close synchronously. The specific linkage structure for the opening and closing of the first door 2 and the second door 3 is prior art and will not be described in detail here.

[0032] Furthermore, the second door 3 is also secured to the dishwasher's cabinet 1 using a magnetic attraction structure. Specifically, a second limiting part 31 is installed on the side of the second door 3 facing the cabinet 1, and a magnetic block 7 is installed on the cabinet 1. When the second door 3 is closed, the second limiting part 31 is positioned opposite the magnetic block 7, and the magnetic block 7 can magnetically attract the second limiting part 31. By using a magnetic attraction structure for both the first door 2 and the second door 3 of the dishwasher to close, the number of mechanical components in the dishwasher can be reduced, simplifying the dishwasher's structure.

[0033] Furthermore, referring to Figure 5 As shown, in this embodiment, the electromagnet device 6 is a traction electromagnet, including a retractable iron core 61. When the electromagnet device 6 is energized, the iron core 61 generates magnetism and retracts under the influence of magnetism. The iron core 61 has a head 62, which faces the first limiting part 21 of the first door 2. When the first door 2 is closed, the head 62 of the iron core 61 and the first limiting part 21 are magnetically attracted by the electromagnet device 6. Figure 5 In the middle, the iron core 61 of the electromagnet device 6 is in a state where it does not extend beyond the side edge of the box. The length of the iron core 61 can also be adjusted appropriately as needed so that the end head 62 of the iron core 61 can be magnetically attracted to the first limiting part 21.

[0034] Reference Figure 5 As shown, a spring 63 is installed between the end head 62 of the iron core 61 and the electromagnet device body. The spring 63 abuts against the end head 62 of the iron core 61 and can elastically act on the first limiting part 21 through the spring 63.

[0035] Specifically, when the electromagnet device 6 is turned on, it generates magnetism, and the end 62 of the iron core 61 is magnetically attracted to the first limiting part 21. The iron core 61 retracts and drives the first door 2 to close, which can generate a pulling action on the first door 2 in the closing direction.

[0036] When the electromagnet 6 is deactivated and its magnetism is eliminated, the spring 63 elastically pushes the iron core 61 towards the first door 2, opening the first door 2. Furthermore, the elasticity of the spring 63 pushes the iron core 61 outward, effectively pushing the first door 2 in the opening direction. By controlling the on / off state of the magnet, the opening and closing of the first door 2 can be achieved, enabling the dishwasher to automatically open and close.

[0037] Furthermore, the first limiting part 21 is a permanent magnet, which can actively magnetically attract the iron core 61. Even when the electromagnet device 6 is de-energized and demagnetized, when the first door 2 is close to the closed state, the first limiting part 21 can still magnetically attract the iron core 61, thereby facilitating the initial limiting of the door and the subsequent magnetic closing action.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
