Description
Technical Field
[0001] The utility model relates to the technical field of kitchen appliances, in particular to a door handle and a cooking device. Background Art
[0002] At present, for cooking devices such as built-in ovens / steamers sold on the market, there is a door on the front for opening / closing the cooking cavity. Usually, the handle is set above the door and protrudes outwards. After the built-in cooking device is installed, the handle is exposed outside the cabinet, and it is easy for users to collide with the handle when walking in the kitchen, causing injury to the users.
[0003] To avoid the above problems, in the prior art, a door handle is designed. The handle is hinged to the door body. When the user needs to pull the door body through the handle, the handle protrudes from the door body to facilitate the user to pull the door body through the handle; when the user has no intention of pulling the door body, the handle retracts towards the direction close to the door body so that the handle is flush with the surface of the door body. This setting can effectively solve the problem that the user is easy to collide with the handle when walking in the kitchen. However, when the user pulls the handle, since the handle is hinged to the door body, it is very easy to cause the handle and the door body to collide, and then cause mechanical damage to the door body.
[0004] Therefore, there is an urgent need for a door handle to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to provide a door handle and a cooking device to solve the problem in the related technology that when the user pulls the handle, since the handle is hinged to the door body, it is very easy to cause the handle and the door body to collide, and then cause mechanical damage to the door body.

The main rotating plate is provided with a limiting protrusion, and the secondary rotating plate is provided with a limiting groove. When the handle switches to the first position, the inner walls of the limiting protrusion and the limiting groove are in contact.
[0009] As a preferred technical solution of the door handle, the limiting groove includes a first limiting surface and a second limiting surface that forms an angle with the first limiting surface. When the handle is switched to the first position, the limiting protrusion abuts against the first limiting surface. When the handle is switched to the second position, the limiting protrusion abuts against the second limiting surface.
[0010] As a preferred technical solution of the door handle, the limiting groove further includes a connecting surface, which is located between the first limiting surface and the second limiting surface and is connected to the first limiting surface and the second limiting surface respectively.
[0011] As a preferred technical solution of the door handle, the limiting groove is formed by bending the secondary rotating plate.
[0012] As a preferred technical solution of the door handle, the limiting protrusion includes a first abutting surface and a second abutting surface. When the handle is switched to the first position, the first abutting surface fits and abuts against the first limiting surface. When the handle is switched to the second position, the second abutting surface fits and abuts against the second limiting surface.
[0013] As a preferred technical solution of the door handle, the limiting protrusion is formed by bending the main rotating plate.
[0014] As a preferred technical solution of the door handle, along the pivot axis of the secondary rotating plate and the handle, two side limiting plates are arranged at intervals on the secondary rotating plate, and the main rotating plate is arranged between the two side limiting plates.
[0015] As a preferred technical solution of the door handle, the handle includes a pulling part and a pivot seat fixed on the pulling part. The pivot seat is provided with two pivot ears at intervals along the pivot axis of the secondary rotating plate and the handle. The main pivot shaft sequentially passes through one pivot ear, one end of the main rotating plate, and the other pivot ear. The secondary pivot shaft sequentially passes through one pivot ear, one end of the secondary rotating plate, and the other pivot ear.
[0016] As a preferred technical solution of the door handle, at least two hinge assemblies are provided, and at least two hinge assemblies are arranged at intervals along the axial direction of the pivot axis of the secondary rotating plate and the handle.

[0037] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0038] As Figures 1 to 4 shown, the present utility model provides a cooking device, including a cooking cavity 100, a door body 200, and a door handle. The cooking cavity 100 has an opening. The door body 200 is pivotally connected to the cooking cavity 100 through a hinge for opening and closing the opening. The handle 1 is movably connected to the door body 200 through a hinge assembly 2.
[0039] Optionally, the door body 200 includes an inner door panel 201, outer glasses 202 and inner glasses 203 disposed on both sides of the inner door panel 201. When the door body 200 closes the opening, the inner glass 203 faces the opening. A control panel 300 is disposed at an interval above the door body 200. The handle 1 is movably connected above the door body 200. When the handle 1 is in the second position, the handle 1 closes the gap between the door body 200 and the control panel 300, and at this time, the door body 200, the handle 1, the outer glass 202 and the control panel 300 are in the same plane. In other embodiments, the handle 1 can also be located behind the outer surface of the outer glass 202, and this setting can avoid the handle 1 causing harm to the user. When the handle 1 is in the first position, the handle 1 is in front of the outer surface of the outer glass 202, and this position can facilitate the user to grasp the handle 1.
[0040] Regarding the specific structure of the door handle, as Figures 1 to 8As shown in the figure, the door handle includes a handle 1 and a hinge assembly 2. The hinge assembly 2 includes a main rotating plate 21 and a secondary rotating plate 22. The two ends of the main rotating plate 21 are respectively used for pivoting with the handle 1 and the door body 200. The two ends of the secondary rotating plate 22 are respectively used for pivoting with the handle 1 and the door body 200 to form a four-bar linkage structure. Along the vertical direction, the pivot axis of the secondary rotating plate 22 and the door body 200 is located below the pivot axis of the main rotating plate 21 and the door body 200. The pivot axis of the secondary rotating plate 22 and the handle 1 is located above the pivot axis of the main rotating plate 21 and the handle 1. The main rotating plate 21 is provided with a limiting protrusion 211, and the secondary rotating plate 22 is provided with a limiting groove 221. When the handle 1 switches between the first position and the second position, the main rotating plate 21 and the secondary rotating plate 22 move relative to each other. At this time, the limiting protrusion 211 moves in the limiting groove 221. When the handle 1 is in the first position, the limiting protrusion 211 abuts against the inner wall of the limiting groove 221 to limit the movement of the handle 1. The user can pull the door body 200 to swing relative to the cooking cavity 100 through the handle 1. At this time, while the handle 1 is stressed, due to the limiting protrusion 211 abutting against the inner wall of the limiting groove 221, the relative positions of the main rotating plate 21 and the secondary rotating plate 22 are fixed to limit the movement of the handle 1. Furthermore, it is possible to prevent the force received by the handle 1 from acting on the door body 200 through the hinge assembly 2, and thus it is possible to prevent mechanical damage to the door body 200.
[0041] Specifically, when the handle 1 is in the first position, the side of the door body 200 opposite to the control panel 300 is spaced apart from the hinge assembly 2.
[0042] Optionally, the limiting groove 221 includes a first limiting surface 2211 and a second limiting surface 2212 that forms an angle with the first limiting surface 2211. When the handle 1 switches to the first position, the limiting protrusion 211 abuts against the first limiting surface 2211. When the handle 1 switches to the second position, the limiting protrusion 211 abuts against the second limiting surface 2212. In this embodiment, the first limiting surface 2211 and the second limiting surface 2212 are respectively located on both sides of the limiting protrusion 211. When the handle switches from the second position to the first position, the limiting protrusion 211 moves towards the direction close to the first limiting surface 2211 until the limiting protrusion 211 abuts against the first limiting surface 2211. At this time, the main rotating plate 21 and the secondary rotating plate 22 are relatively fixed, and thus the handle 1 is in the first position. When the handle switches from the first position to the second position, the limiting protrusion 211 moves towards the direction close to the second limiting surface 2212 until the limiting protrusion 211 abuts against the second limiting surface 2212. At this time, the main rotating plate 21 and the secondary rotating plate 22 are relatively fixed, and thus the handle 1 is in the second position.
[0043] Optionally, the limiting groove 221 further includes a connecting surface 2213, which is located between the first limiting surface 2211 and the second limiting surface 2212 and is connected to the first limiting surface 2211 and the second limiting surface 2212 respectively. In this embodiment, setting the connecting surface 2213 can increase the distance between the first limiting surface 2211 and the second limiting surface 2212, and further increase the moving distance of the limiting protrusion 211 in the limiting groove 221, and finally achieve the purpose of increasing the distance between the first position and the second position. Specifically, the length of the connecting surface 2213 is determined according to the required distance between the first position and the second position.
[0044] Optionally, the limiting groove 221 is formed by bending the secondary rotating plate 22. In this embodiment, the above setting can improve the production efficiency of the secondary rotating plate 22 and reduce the production cost of the secondary rotating plate 22. Specifically, the secondary rotating plate 22 is a stamping part, and the limiting groove 221 is formed by stamping. In other embodiments, the limiting groove 221 can also be formed on the secondary rotating plate 22 by processes such as cutting.
[0045] Optionally, the limiting protrusion 211 includes a first abutting surface 2111 and a second abutting surface 2112. When the handle 1 is switched to the first position, the first abutting surface 2111 abuts against and is in contact with the first limiting surface 2211. When the handle 1 is switched to the second position, the second abutting surface 2112 abuts against and is in contact with the second limiting surface 2212. In this embodiment, compared with the point-to-point abutment or point-to-surface abutment, the abutment of the first abutting surface 2111 against the first limiting surface 2211 is a surface-to-surface abutment. Therefore, it can disperse the mutual acting force between the main rotating plate 21 and the secondary rotating plate 22, and further avoid the interaction between the limiting protrusion 211 and the limiting groove 221 when the handle 1 is under excessive force, thereby preventing damage to the main rotating plate 21 and the secondary rotating plate 22. The abutment manner and effect of the second abutting surface 2112 against the second limiting surface 2212 are the same as those of the first abutting surface 2111 against the first limiting surface 2211, and will not be elaborated here.
[0046] Optionally, the limiting protrusion 211 is formed by bending the main rotating plate 21. In this embodiment, the above setting can improve the production efficiency of the main rotating plate 21 and reduce the production cost of the main rotating plate 21. Specifically, the main rotating plate 21 is a stamping part, and the limiting protrusion 211 is formed by stamping. In other embodiments, the limiting protrusion 211 can also be welded to the main rotating plate 21.
[0047] Optionally, along the pivotal axis of the secondary rotating plate 22 and the handle 1, two side limit plates 23 are spaced apart on the secondary rotating plate 22, and the primary rotating plate 21 is disposed between the two side limit plates 23. In this embodiment, the two side limit plates 23 can limit the relative movement of the secondary rotating plate 22 and the primary rotating plate 21 along the pivotal axis of the secondary rotating plate 22 and the handle 1, so as to effectively position the handle 1 relative to the door body 200 along the pivotal axis of the secondary rotating plate 22 and the handle 1, and avoid shaking of the handle 1 when switching between the first position and the second position. Specifically, the two side walls of the primary rotating plate are respectively abutted against the two side limit plates 23.
[0048] Optionally, the handle 1 includes a pulling part 11 and a pivotal connection seat 12 fixed on the pulling part 11. Two pivotal connection ears 121 are spaced apart on the pivotal connection seat 12 along the pivotal axis of the secondary rotating plate 22 and the handle 1. The primary pivotal shaft 24 sequentially passes through one pivotal connection ear 121, one end of the primary rotating plate 21, and the other pivotal connection ear 121, and the secondary pivotal shaft 25 sequentially passes through one pivotal connection ear 121, one end of the secondary rotating plate 22, and the other pivotal connection ear 121. In this embodiment, the pivotal connection seat 12 includes a seat body fixed on the pulling part 11, and the two pivotal connection ears 121 are fixed on the seat body. Optionally, the pivotal connection seat 12 is an integrally formed part.
[0049] In the first position, the pulling part 11 protrudes from the outer surface of the outer glass 202 of the door body 200. When in the second position, the outer surface of the pulling part 11 away from the pivotal connection seat 12 is flush with the outer surface of the outer glass 202 of the door body 200 or is located behind the outer surface of the outer glass 202 of the door body 200. The two pivotal connection ears 121 are spaced apart along the pivotal axis of the secondary rotating plate 22 and the handle 1, and one end of the primary rotating plate 21 and one end of the secondary rotating plate 22 are both located between the two pivotal connection ears 121. Thus, the two pivotal connection ears 121 can limit the sliding of the hinge assembly 2 relative to the pulling part 11 along the pivotal axis of the secondary rotating plate 22 and the handle 1, and further ensure that the side surface of the pulling part 11 along the pivotal axis of the secondary rotating plate 22 and the handle 1 is flush with the outer glass 202, maintaining a good appearance.
[0050] Optionally, at least two hinge assemblies 2 are provided, and the at least two hinge assemblies 2 are spaced apart along the pivotal axis of the secondary rotating plate 22 and the handle 1. In this embodiment, at least two pivotal connection seats 12 are provided on the pulling part 11 of the handle 1, so that the pivotal connection seats 12 and the hinge assemblies 2 correspond to each other one by one. The above setting can make the handle more reliable and stable during the switching process between the first position and the second position, and prevent the problem of jamming due to uneven force.
[0051] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
