[0028] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0029] The present utility model provides a door body hinge assembly and a dishwasher. Multiple embodiments are given below to describe in detail the door body hinge assembly and the dishwasher provided by the present utility model.

[0030] Embodiment 1

[0031] The door body hinge assembly provided in this embodiment, as Figures 1 to 6 shown, includes a pin shaft 51 and a hinge plate 1; the hinge plate 1 is provided with a first opening groove 11 and a second opening groove 15 at intervals; the opening of the first opening groove 11 faces the outside of the door body, and the first opening groove 11 is sleeved on the pin shaft 51; an anti - detachment tongue 12 is formed between the first opening groove 11 and the second opening groove 15; the anti - detachment tongue 12 can move to the opening of the first opening groove 11 to block the opening of the first opening groove 11.

[0032] When the door lining 71 is installed, the first opening groove 11 is sleeved on the pin shaft 51. In order to prevent the first opening groove 11 from being separated from the pin shaft 51, a tool is inserted into the second opening groove 15, and the tool is pulled in the direction of the anti-slip tongue 12 to drive the anti-slip tongue 12 to move to the opening of the first opening groove 11, so that the anti-slip tongue 12 blocks the opening of the first opening groove 11 to prevent the pin shaft 51 from being separated from the opening of the first opening groove 11, thereby achieving the purpose of preventing the hinge plate 1 from being separated from the pin shaft 51.

[0033] Since the size requirements of the hinge plate 1 of the thin door dishwasher are relatively high and the width of the hinge plate 1 is relatively small, there is no space for opening the first opening groove 11 on the side of the hinge plate facing the bottom end of the door body, and there is space for opening the first opening groove 11 only on the side of the hinge plate facing the outside of the door body. Therefore, the first opening groove 11 needs to be opened on the side of the hinge plate facing the outside of the door body, and the opening of the first opening groove 11 is set toward the outside of the door body, so that the door hinge assembly can be suitable for thin door dishwashers.

[0034] The second opening groove 15 can provide an operating space for tool operation, making the operation more convenient.

[0035] The door hinge assembly provided in this embodiment has a simple structure design and small space occupation, and can be applied to dishwashers with thin doors. The door hinge assembly has an anti-detachment function, is more stable, prevents the dishwasher door 7 from detaching from the dishwasher body, and increases product stability.

[0036] In order to enable the anti-slip tongue 12 to move to the opening of the first opening groove 11, in an optional embodiment, the anti-slip tongue 12 is rotatably connected to the hinge plate 1. After the anti-slip tongue 12 is rotated relative to the hinge plate 1 to the opening of the first opening groove 11, the anti-slip tongue 12 can be fixed to the hinge plate 1 (for example, by bonding or connecting with fasteners, etc.), thereby locking the anti-slip tongue 12 at the opening of the first opening groove 11, so that the anti-slip tongue 12 blocks the opening of the first opening groove 11.

[0037] Preferably, the end of the anti-slip tongue 12 facing the hinge plate 1 has a deformation structure 13 , and the deformation structure 13 can be deformed to drive the anti-slip tongue 12 to move to the opening of the first opening groove 11 .

[0038] After the first opening groove 11 is sleeved on the pin shaft 51, a flat-blade (or F-shaped) tool can be used to insert it into the second opening groove 15 and move it in the direction of the anti-slip tongue 12 (such as Figure 1 The tool is lifted in the upward direction, at which time one end of the tool abuts against the fulcrum 16 in the second opening groove 15, and the other end of the tool abuts against the fulcrum 2 14 on the anti-slip tongue 12. Under the action of the pulling force, the deformation structure 13 is deformed, thereby driving the anti-slip tongue 12 to move to the opening of the first opening groove 11, and the anti-slip tongue 12 blocks the opening of the first opening groove 11 to prevent the pin shaft 51 from falling off the first opening groove 11.

[0039] Drive the deformation structure 13 to deform, so that when driving the anti - detachment tongue 12 to move to the opening of the first opening groove 11. The deformation structure 13 can deform, and the deformation structure 13 is made of a material that can deform, such as metal.

[0040] The hinge plate 1, the deformation structure 13 and the anti - detachment tongue 12 are fixedly connected in sequence. The connection method can be bonding or welding, or it can be an integrally formed structure.

[0041] In this embodiment, the hinge plate 1, the deformation structure 13 and the anti - detachment tongue 12 are integrally formed structures, and the hinge plate 1, the deformation structure 13 and the anti - detachment tongue 12 are all made of metal.

[0042] Furthermore, both the anti - detachment tongue 12 and the deformation structure 13 are made of metal materials; the width of the deformation structure 13 is smaller than the width of the end of the anti - detachment tongue 12 facing the deformation structure 13. The smaller width of the deformation structure 13 makes it easy for the deformation structure 13 to bend and deform under external force.

[0043] In Figure 1 as shown, in the plane where the end face of the anti - detachment tongue 12 is located ( Figure 1 the vertical plane shown in

[0044] ), the direction perpendicular to the extension direction of the deformation structure 13 is the width direction of the deformation structure 13, and the direction perpendicular to the extension direction of the anti - detachment tongue 12 is the width direction of the anti - detachment tongue 12. Figure 2 In

[0045] Furthermore, the first opening groove 11 is arc - shaped.

[0046] The first opening groove 11 is sleeved on the pin shaft 51. The first opening groove 11 is arc - shaped, so that the first opening groove 11 can better adapt to the pin shaft 51, making the rotation of the hinge plate 1 around the pin shaft 51 smoother and more stable.

[0047] Furthermore, the surface of the anti - detachment tongue 12 facing the pin shaft 51 is an arc surface.

[0048] When the anti - detachment tongue 12 moves to the opening of the first opening groove 11, the surface of the anti - detachment tongue 12 facing the pin shaft 51 is an arc surface, enabling the anti - detachment tongue 12 to better adapt to the pin shaft 51 and making the rotation of the hinge plate 1 around the pin shaft 51 smoother and more stable.

[0049] The opening of the second opening groove 15 can be arranged facing the outside of the door body or can be arranged obliquely downward relative to the outside of the door body.

[0050] Preferably, the opening of the second opening groove 15 is arranged facing the outside of the door body, which is convenient for tools to be inserted into the second opening groove 15, facilitating the application of force by the tools and improving the convenience of operation.

[0051] The second opening groove 15 can be arranged on one side of the first opening groove 11 facing the top of the door body or can be arranged on one side of the first opening groove 11 facing the bottom of the door body.

[0052] In this embodiment, the second opening groove 15 is arranged on one side of the first opening groove 11 facing the bottom of the door body. When driving the anti - detachment tongue 12 to move to the opening of the first opening groove 11, a tool can be inserted into the groove 17 of the second opening groove 15 and lifted upward. The operation is relatively simple and it is convenient for the tool to apply force.

[0053] Furthermore, a groove 17 is provided on the side wall of the second opening groove 15 away from the anti - detachment tongue 12.

[0054] When driving the deformation structure 13 to deform, thereby driving the anti - detachment tongue 12 to move to the opening of the first opening groove 11, a flat - bladed (or F - shaped) tool can be inserted into the groove 17 of the second opening groove 15 and the tool can be lifted in the direction of the anti - detachment tongue 12. At this time, one end of the tool abuts against the first fulcrum 16 in the groove 17, and another point on the tool abuts against the second fulcrum 14 on the anti - detachment tongue 12. Under the action of the pulling force, the deformation structure 13 deforms, thereby driving the anti - detachment tongue 12 to move to the opening of the first opening groove 11, and the anti - detachment tongue 12 blocks the opening of the first opening groove 11 to prevent the pin shaft 51 from falling off from the first opening groove 11.

[0055] When the tool is inserted into the groove 17 during operation, it can prevent the tool from slipping out of the second opening groove 15 after being stressed.

[0056] Among them, as Figure 2 shown, the side of the groove 17 facing the bottom wall can be communicated with the bottom wall of the second opening groove 15.

[0057] Furthermore, an anti - slip structure is provided on the surface of the groove 17.

[0058] Anti - slip protrusions or anti - slip patterns can be set on the surface of the groove 17, or an anti - slip layer can be set on the surface of the groove 17.

[0059] The surface of the groove 17 is provided with an anti-slip structure, so that after the tool is inserted into the groove 17, the friction between the tool and the groove 17 is increased, which can further prevent the tool from sliding out of the second opening groove 15 after being stressed.

[0060] Further, the hinge plate 1 includes a hinge arm 18, and reinforcing structures are respectively arranged on both sides of the hinge arm 18.

[0061] Reinforcing structures are respectively arranged on the edge regions on both sides of the hinge arm 18, which can increase the strength of the hinge arm 18 and improve the stability and service life of the hinge plate 1.

[0062] The reinforcing structure can be a reinforcing rib or any suitable structure such as a reinforcing protrusion.

[0063] Further, a first reinforcing rib 181 is arranged on the side of the hinge arm 18 facing away from the door body; a second reinforcing rib 182 and a reinforcing boss 183 are arranged on the side of the hinge arm 18 facing the door body.

[0064] A first reinforcing rib 181 is arranged on the edge region on the side of the hinge arm 18 facing away from the door body, a second reinforcing rib 182 is arranged on the edge region on the side of the hinge arm 18 facing the door body, and a connecting structure 3 is arranged on the side of the hinge arm 18 facing the door body for connecting with the door lining 71. A reinforcing boss 183 is arranged at a position corresponding to the connecting structure 3 on the side of the hinge arm 18 facing the door body.

[0065] Further, the door hinge assembly further includes a hinge fixing plate 5, and a pin shaft 51 is arranged on the hinge fixing plate 5; the hinge fixing plate 5 is provided with a blocking structure 52, and the hinge plate 1 is provided with a stop structure 19. When the hinge plate 1 rotates to the open position, the stop structure 19 abuts against the blocking structure 52.

[0066] The blocking structure 52 can be in the form of a plate or any suitable form such as a block, and the stop structure 19 can be in the form of a plate or any suitable form such as a block.

[0067] The hinge plate 1 rotates relative to the hinge fixing plate 5 continuously. When the hinge plate 1 rotates to the open position of the door body, the stop structure 19 abuts against the blocking structure 52, and the hinge plate 1 cannot continue to rotate in the opening direction. At this time, the opening angle of the door body is the largest, and the maximum opening angle of the door body is R, where 89°≥R≥85°.

[0068] In addition, a drawstring hook 2 is also arranged on the hinge plate 1.
