[0058] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0059] The present application discloses a door assembly of a cooking appliance 100.

[0060] The door assembly of the cooking appliance 100 according to the embodiments of the present application is described below with reference to Figures 1-20 The door assembly of the cooking appliance 100 according to the embodiments of the present application is described below with reference to

[0061] In some embodiments, as shown in Figure 1 and Figure 11 The door assembly of the cooking appliance 100 according to the embodiments of the present application is described below with reference to

[0062] The door body 110 can be used to block the cooking cavity 161 to provide a closed cooking environment for food, the door body 110 can be provided with a transparent window, the transparent window can be used to observe the state of the food being cooked, and a handle can be provided on the outer plate of the door body 110, the handle can be used to facilitate the user to pull the door body 110.

[0063] The lock hook 120 is rotatably installed between the first position and the second position of the door body 110, and at least part of the lock hook 120 extends from the back plate of the door body 110, the lock hook 120 is adapted to be locked with the main machine 160 of the cooking appliance 100 in the first position, and the lock hook 120 is adapted to be unlocked with the main machine 160 of the cooking appliance 100 in the second position.

[0064] The lock hook 120 can be used to lock the door body 110 and the main machine 160. The lock hook 120 can be made of metal or plastic, for example, in some embodiments, the lock hook 120 is made of plastic, which can include, but is not limited to, PP (Polypropylene), POM (Polyformaldehyde), or PC (Polycarbonate), etc.

[0065] As shown in Figure 1 and Figure 11 , a part of the lock hook 120 can be located in the door body 110, and another part of the lock hook 120 can penetrate the back plate of the door body 110 and extend into the main machine 160 of the cooking appliance 100, so that at least part of the lock hook 120 is locked with the main machine 160 of the cooking appliance 100.

[0066] It can be understood that, as shown in Figures 7-10 , the rotation angle of the lock hook 120 from the first position to the second position can be 90°, in other words, the lock hook 120 located in the first position can reach the second position after rotating 90°, that is, the lock hook 120 can rotate back and forth between the first position and the second position, thereby realizing the locking and unlocking between the door body 110 and the main machine 160.

[0067] The operation part 130 is connected with the lock hook 120, and the operation part 130 is at least used to drive the lock hook 120 to rotate from the first position to the second position.

[0068] The connection mode between the operation part 130 and the lock hook 120 can include, but is not limited to, interference fit, integral molding or adhesion, etc., for example, in some embodiments, the connection mode between the operation part 130 and the lock hook 120 is integral molding.

[0069] It should be noted that the lock hook structure of the present application can be a safety lock of the cooking appliance 100, that is, the above-mentioned lock hook structure is the first lock of the cooking appliance 100, and the user cannot directly pull the door to release the first lock. The cooking appliance 100 itself has a resilient door lock, which is the second lock of the cooking appliance 100, and the user can use a small force to pull the handle outward to release the resilient door lock.

[0070] In actual implementation, the operation part 130 can be a handle, and the handle can be a pull handle or a push handle. Figures 7-10For example, the operation part 130 can be at least partially exposed to the outside to facilitate user manipulation. In the case where the door body 110 needs to be opened to take out food after food cooking is completed, at this time, the door body 110 is in a closed state and the locking hook 120 is located at the first position, the user can manipulate the operation part 130, so that the locking hook 120 rotates 90° toward the second position, and the locking hook 120 reaches the second position, at this time, the first lock of the cooking appliance 100 is released, the user holds the handle, and the door body 110 can be pulled out with a small force, and with the release of the second lock, the door body 110 and the main machine 160 of the cooking appliance 100 can also be unlocked correspondingly.

[0071] In the related art, to prevent children from opening the door body by mistake, some cooking appliances are also provided with a child lock structure. The child lock structure is mounted on the door body, at least part of the child lock structure extends out of the side plate of the door body, and is clamped with the main machine of the cooking appliance. Meanwhile, the operation part of the child lock structure is arranged below the front plate of the door body.

[0072] However, in actual use, the above-mentioned scheme has many disadvantages. Since the child lock structure is located on the side plate of the door body, the side plate of the door body needs to be slotted to allow the child lock structure to extend out, so that impurities and dirt are easily introduced into the door body, increasing the difficulty of cleaning the cooking appliance. In addition, the operation part is arranged on the front plate facing the user, and the height of the operation part is relatively low, so that children can easily touch the operation part, thereby slightly weakening the protection effect of the child lock.

[0073] In the embodiment, at least part of the locking hook 120 extends from the back plate of the door body 110. Compared with the scheme in which the locking hook 120 extends from the side plate of the door body 110, in daily use, impurities and dirt are not easily introduced into the door body 110, facilitating the cleaning work of the cooking appliance 100. In addition, the operation part 130 is located above the door body 110. Since the operation part 130 does not directly face the user and the height of the operation part 130 is relatively large, children can hardly easily touch the operation part 130, so that the safety of the child lock structure is ensured.

[0074] The door assembly of the cooking appliance 100 provided by the embodiment of the present application adds a mechanical child lock structure on the basis of the original door opening system, to ensure that the child lock must be released before the door opening action is completed, so that the entire door opening action can be completed, preventing children from being scalded by touching hot food after opening the door body 110, and helping to improve the safety and reliability of the entire cooking appliance 100.

[0075] In some embodiments, as shown in FIG. 1, Figure 1 The door body 110 can include a door frame body 111 and a door shell 113.

[0076] The lock hook 120 can be rotatably installed between the first position and the second position of the door frame body 111, and the back plate of the door frame body 111 can be provided with an avoiding slot, and the lock hook 120 extends from the avoiding slot; the door shell body 113 can be installed outside the door frame body 111, and the door shell body 113 can have an avoiding opening 114, and the operation part 130 can penetrate through the avoiding opening 114.

[0077] The connection mode between the door frame body 111 and the door shell body 113 can include but is not limited to bolt connection, pin shaft connection or buckle connection, etc., for example, in some embodiments, the connection mode between the door frame body 111 and the door shell body 113 is bolt connection.

[0078] In this embodiment, the lock hook 120 can penetrate through the avoiding slot, and at least part of the lock hook 120 can extend into the main machine 160 of the cooking utensil 100, the size of the avoiding opening 114 can be greater than the size of the operation part 130, and the size of the avoiding opening 114 can meet that the operation part 130 can at least drive the lock hook 120 to rotate from the first position to the second position, in other words, the lock hook 120 can rotate back and forth within the limiting range of the avoiding slot and the avoiding opening 114.

[0079] The door assembly of the cooking utensil 100 provided by the embodiment of the present application is designed by the above-mentioned door frame body 111 and door shell body 113, and the avoiding slot and the avoiding opening 114, so that the lock hook 120 can rotate back and forth between the first position and the second position under the limiting action, ensuring that the child lock structure can be normally locked and unlocked, and at the same time, the overall structure design is simple, the connection mode is flexible and smooth, and the use and experience of the user are improved.

[0080] The embodiment of the present application will be described in detail from two different implementation angles respectively.

[0081] I. The lock hook 120 rotates around the front-back direction.

[0082] In some embodiments, as shown in Figures 1-3 The lock hook 120 can be rotatably installed around the first axis of the first frame 112 of the door body 110, the first axis can extend along the front-back direction, and the first frame 112 can be a frame opposite to the pivot axis of the door body 110.

[0083] In this embodiment, as shown in Figures 1-3As shown, the pivot axis can be a rotation axis between the door body 110 and the main machine 160, the first frame 112 can be detachably connected with the main machine 160, the pivot axis and the first frame 112 can be oppositely arranged, and the first axis can be perpendicular to the first frame 112. During unlocking of the door body 110, the user pulls the operation part 130, the operation part 130 can drive the lock hook 120 to rotate around the first axis until the lock hook 120 rotates from the first position to the second position, and the child lock structure is unlocked. At this time, the handle on the door body 110 is pulled, the first frame 112 can be separated from the main machine 160 of the cooking utensil 100, and the door body 110 can rotate around the pivot axis, that is, the first frame 112 can rotate around the pivot axis.

[0084] The door assembly of the cooking utensil 100 provided by the embodiment of the present application is arranged in the above-mentioned manner, that is, the first axis is arranged in the direction, and the lock hook 120 can rotate back and forth between the first position and the second position around the first axis. The operation part 130 can be pulled to complete the preliminary unlocking, thereby reducing the operation difficulty of the user.

[0085] In some embodiments, as shown in Figure 1 and Figure 3 The pivot axis of the door body 110 can be located at the lower frame of the door body 110, and the first frame 112 can be the upper frame of the door body 110.

[0086] In actual implementation, based on the pivot axis of the door body 110 being located at the lower frame of the door body 110, considering the opening force of the user, the handle can be installed at the position close to the upper frame of the door body 110. In the case that the food is cooked and the door body 110 needs to be opened to take out the food, the user can pull the operation part 130, the operation part 130 can drive the lock hook 120 to rotate in the front-back direction until the lock hook 120 rotates from the first position to the second position. At this time, the first lock of the cooking utensil 100 is unlocked, the user holds the handle, and a small force can be used to pull the door body 110. The first frame 112 can be separated from the main machine 160 of the cooking utensil 100, and the first frame 112 can rotate downward around the pivot axis. With unlocking of the second lock, the door body 110 and the main machine 160 of the cooking utensil 100 can also be unlocked.

[0087] Alternatively, the pivot axis of the door body 110 can be located at the left or right side frame of the door body 110, and the first side frame 112 can be arranged at the opposite side of the pivot axis. In actual implementation, the user can pull the operation part 130, and the operation part 130 can drive the hook 120 to rotate around the front-back direction until the hook 120 slides from the initial position to the unlocking position. At this time, the first lock of the cooking appliance 100 is released, the user holds the handle, and a small force can be used to pull the door body 110, the first side frame 112 can be separated from the main machine 160 of the cooking appliance 100, and the first side frame 112 can rotate to the left or right side around the pivot axis. With the release of the second lock, the door body 110 and the main machine 160 of the cooking appliance 100 can also be unlocked accordingly.

[0088] The door assembly of the cooking appliance 100 provided by the embodiments of the present application has the following advantages. The unlocking structure design of the lower opening door makes the cooking appliance 100 occupy a smaller space, improves the volume utilization rate, and facilitates overall layout. The lower pull door type door body 110 can be used for transitional hot cooking of hot food, facilitates the user to take and place food, and thus optimizes the overall experience of the machine.

[0089] In some embodiments, as shown in Figures 4-5 The hook 120 can include a hook body 121.

[0090] The hook body 121 can be rotationally connected with the door body 110, and one end of the hook body 121 can be provided with a hook body 122 for locking with the main machine 160. The hook body 122 can be oriented in a direction parallel to the pivot axis of the door body 110, and the operation part 130 can be connected with the hook body 121.

[0091] It can be understood that, as shown in Figures 4-5 The operation part 130 can be integrally formed with the hook body 121, and the operation part 130 can be arranged at one end of the hook body 121 in the vertical direction, and the hook body 122 can be arranged at the other end of the hook body 121 in the horizontal direction.

[0092] In actual implementation, as shown in Figures 7-10 The user can pull the operation part 130, and the operation part 130 can drive the hook body 122 to rotate around the front-back direction until the hook 120 rotates from the first position to the second position. In the process of rotation, the orientation of the hook body 122 gradually changes from the horizontal direction to the vertical direction, the first lock of the cooking appliance 100 is released, the user holds the handle, and a small force can be used to pull the door body 110, the first side frame 112 can be separated from the main machine 160 of the cooking appliance 100, and the first side frame 112 can rotate downward around the pivot axis. With the release of the second lock, the door body 110 and the main machine 160 of the cooking appliance 100 can also be unlocked accordingly.

[0093] The door assembly of the cooking utensil 100 provided in the embodiments of the present application achieves the driving of the operation part 130 and the rotational locking of the hook body 122 through the arrangement of the above-mentioned hook main body 121 and the connecting segment 125, and integrates the operation part 130 and the hook 120, thereby enhancing the structural reliability and making the operation more convenient and fast.
