[0040] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0041] The following is for reference. Figures 1-6 This application describes a cooking appliance according to an embodiment of the present application.

[0042] This application provides a cooking appliance, such as... Figure 1 As shown, the cooking appliance can be a microwave oven, oven, or steam oven, etc., and the cooking appliance includes a main unit 100 and a door 200.

[0043] Among them, such as Figure 1 As shown, the host 100 has a cooking cavity for placing food, which can be a rectangular structure, a circular structure, or other shapes.

[0044] like Figure 1 As shown, the main unit 100 can be used to cook food through temperature control and time control. The cooking cavity can be used as a container to provide a closed environment for food in conjunction with the door assembly. The door 200 is installed on the main unit 100 in an openable and closable manner to close the cooking cavity. The door 200 can be provided with a handle 210 at the upper position of its front end face.

[0045] One of the front panel of the main unit 100 and the door 200 is provided with a slot, and the other is provided with a door hook for engaging with the slot. For example, the front panel of the main unit 100 may have a slot on its side, and the door 200 may have a door hook on its side corresponding to the slot. Alternatively, the front panel of the main unit 100 may have a door hook on its side, and the door 200 may have a slot on its side corresponding to the slot. The engagement of the door hook with the slot can lock or unlock the door 200 and the main unit 100.

[0046] The door hook engages with the slot to create a second lock on the door assembly. After the door hook is unlocked, the door body 200 needs to be pulled to separate the door hook from the slot to perform a second unlocking operation before the door body 200 can be fully opened.

[0047] The door hook can be movably installed on the door body 200 and extends toward the front plate of the host 100. The latching part of the door hook can move elastically in the vertical direction, and a guide slope is provided in the latching groove.

[0048] like Figure 1As shown, one of the main unit 100 and the door 200 is provided with an elastic clip 300, and the other of the main unit 100 and the door 200 is provided with a locking pin 500. For example, the main unit 100 is provided with an elastic clip 300, and the door 200 is provided with a locking pin 500. The elastic clip 300 includes an elastic arm 310 and an elastic element 320 connected to the elastic arm 310. The elastic force of the elastic element 320 is used to constrain the shape of the elastic arm 310. When the door 200 is closed, the locking pin 500 is used to lock the elastic arm 310.

[0049] like Figures 1-6 As shown, the elastic arm 310 can be made of metal or plastic. For example, in some embodiments, the locking hook is made of plastic, which may include, but is not limited to, PP (Polypropylene), POM (Polyformaldehyde), and PC (Polycarbonate).

[0050] like Figures 1-6 As shown, the front end of the elastic arm 310 is bent downward to form a hook shape. The hook-shaped part of the elastic arm 310 is used to lock with the front surface of the locking pin 500. The elastic element 320 is installed on the lower end face of the elastic arm 310 and is connected to the inner sidewall of the hook-shaped part of the elastic arm 310.

[0051] like Figures 1-6 As shown, the stiffness of the locking pin 500 can be greater than the stiffness of the hook-shaped part of the elastic arm 310, and the height of the locking pin 500 can be greater than the height of the hook-shaped part of the elastic arm 310, so that the hook-shaped part of the elastic arm 310 can engage with the locking pin 500 to achieve the first lock of the door 200 and the host 100. At the same time, according to the stiffness of the material, the hook-shaped part of the elastic arm 310 is set to be able to separate from the locking pin 500 under an external force greater than 25N.

[0052] like Figures 1-6 As shown, the hook-shaped portion of the elastic arm 310 can be an arc structure, and the top end of the locking pin 500 can also be an arc structure, so as to facilitate the relative movement between the hook-shaped portion of the elastic arm 310 and the locking pin 500.

[0053] In actual implementation, such as Figure 2 and Figure 4 As shown, when the door 200 is in the closed state, the locking pin 500 is located inside the elastic arm 310. At this time, the hook-shaped part of the elastic arm 310 abuts against the front end face of the locking pin 500, and the hook end of the door hook is located in the slot and engages with the slot for limitation.

[0054] like Figure 5As shown, when the door 200 needs to be opened, the elastic arm 310 is pulled upward. One end of the elastic arm 310 with a hook-shaped portion begins to lift upward under an external force greater than 25N, while the other end of the elastic arm 310 remains stationary, so that the hook-shaped portion of the elastic arm 310 separates from the front end face of the locking pin 500, raising the hook-shaped portion of the elastic arm 310 to above the locking pin 500 or in contact with the top of the locking pin 500. Since the hook-shaped portion at the front end of the elastic arm 310 has a partial rearward displacement during the upward lifting process, and the elastic element 320 is connected to the hook-shaped portion of the elastic arm 310, the elastic element 320 is in a compressed state during the lifting of the hook-shaped portion of the elastic arm 310.

[0055] Pulling handle 210 applies an external force to both handle 210 and door 200 towards the front of door 200. Under this force, the locking pin 500 tends to move outwards from the elastic arm 310. If the hook-shaped portion of the elastic arm 310 is positioned above the locking pin 500, the first lock formed by the elastic arm 310 and the locking pin 500 is fully open. Continuing to pull door 200 applies an upward pushing force to the guide slope within the slot, causing the hook to move upwards and gradually disengage from the slot, thus opening the door. The slot and the door hook then... The second lock is in the open state, allowing food to be placed or retrieved into the cooking cavity. If the hook-shaped portion of the elastic arm 310 contacts the top of the locking pin 500, the locking pin 500, under the action of pulling the handle 210, applies an external force to the hook-shaped portion of the elastic arm 310, causing it to lift upwards. Under this force, the end of the elastic arm 310 with the hook-shaped portion gradually lifts upwards, and the locking pin 500 gradually moves to the outside of the elastic arm 310 until the two are completely separated and the fully open state is reached. Then, the handle 210 can be pulled to unlock the door hook from the slot.

[0056] When the elastic arm 310 is unlocked from the locking pin 500, the elastic arm 310 is released to remove the external force applied to the elastic arm 310, and the end of the elastic arm 310 with the hook-shaped portion is reset under the action of the forward elastic force of the elastic member 320.

[0057] like Figure 6As shown, when the door 200 needs to be closed, push the door 200 to rotate it toward the host 100 until the top of the locking pin 500 abuts against the outer side of the hook-shaped portion of the elastic arm 310. Under the external force of the locking pin 500, the hook-shaped portion of the elastic arm 310 bends and deforms inward. During the deformation process, the hook-shaped portion of the elastic arm 310 causes the elastic element 320 to be in a compressed state. The deformed hook-shaped portion allows the locking pin 500 to move out of the hook-shaped portion of the elastic arm 310. The lower part passes through and is located inside the elastic arm 310. When the locking pin 500 is completely inside the elastic arm 310, the external force that the locking pin 500 gives to the elastic arm 310, which can deform the hook-shaped part, is removed. At this time, the hook-shaped part of the elastic arm 310 is reset under the elastic force of the elastic member 320, and the hook-shaped part of the elastic arm 310 abuts against the front end face of the locking pin 500 to close the first lock. At the same time, the door hook and the slot also engage to close the second lock.

[0058] By setting up the elastic clip 300, the locking pin 500, the door hook, and the slot, two locks are provided for the opening and closing of the door 200 relative to the host 100. The door 200 can only be opened after the first lock formed by the elastic clip 300 and the locking pin 500 and the second lock formed by the door hook and the slot are opened in sequence. Moreover, opening the first lock formed by the elastic clip 300 and the locking pin 500 requires an external force of more than 25N. Therefore, for children, opening the first lock requires a lot of force and cannot be easily opened. This reduces the risk of children being burned by hot food inside cooking utensils, thus improving the safety of cooking utensils. At the same time, the elastic element 320 realizes the reset of the elastic arm 310, which can avoid the situation where the elastic arm 310 cannot be fully reset after multiple deformations, resulting in the failure of locking with the locking pin 500, and extends the service life of the elastic clip 300.

[0059] According to the embodiments of this application, the cooking appliance provided by setting the first lock formed by the elastic arm 310 and the locking pin 500 can increase the difficulty for children to open the cooking appliance, thereby reducing the risk of children being burned by hot food inside the cooking appliance and improving the safety of the cooking appliance.

[0060] In some embodiments, such as Figure 2 and Figure 4 As shown, when the door 200 is closed, the elastic arm 310 is in perpendicular contact with the locking pin 500.

[0061] Among them, such as Figure 2 and Figure 4As shown, the tangent of the highest point of the arc structure of the hook-shaped part of the elastic arm 310 is set to be perpendicular to the vertical line of the front end face of the locking pin 500 when the door 200 is closed. That is, when the door 200 is closed, the highest point of the arc structure of the hook-shaped part of the elastic arm 310 abuts against the front end face of the locking pin 500, and the two are in a perpendicular contact state, and the elastic arm 310 does not deform.

[0062] The cooking appliance provided in this application embodiment ensures that the elastic arm 310 and the locking pin 500 are in vertical contact when the door 200 is closed, thus requiring a child to use a force of more than 25N to unlock the elastic arm 310 and the locking pin 500, thereby further improving the safety of the cooking appliance.

[0063] In some embodiments, such as Figure 2 and Figure 4 As shown, when the door 200 is closed, the elastic arm 310 and the locking pin 500 stop at the target position, and the angle between the normal of the elastic arm 310 at the target position and the normal of the locking pin 500 at the target position is α, which satisfies: α≤5°.

[0064] Among them, such as Figure 2 and Figure 4 As shown, when the door 200 is closed, the hook-shaped part of the elastic arm 310 abuts against the front end face of the locking pin 500. Since the hook-shaped part of the elastic arm 310 is an arc structure, the actual contact area between the hook-shaped part of the elastic arm 310 and the locking pin 500 is a linear target position area extending along the left and right direction of the host 100.

[0065] like Figure 2 and Figure 4 As shown, since the top of the locking pin 500 is an arc structure, if the linear target position is located on the arc structure part of the locking pin 500, then the normal of the locking pin 500 at the linear target position is the tangent of the arc structure part at the point of the linear target position. The front end face of the locking pin 500 is a plane. If the linear target position is located on the front end face of the locking pin 500, then the normal of the locking pin 500 at the linear target position is a perpendicular line that is parallel to the front end face and perpendicular to the linear target position. Similarly, the normal of the elastic arm 310 at the linear target position is the tangent of the arc structure part at the point of the linear target position.

[0066] The first lock can stop with the locking pin 500 by the linear target position where the highest point of the arc structure of the hook-shaped part of the elastic arm 310 is located, or by the part of the arc structure other than the highest point. However, the angle between the normal of the elastic arm 310 at the linear target position and the normal of the locking pin 500 at the linear target position must be less than or equal to 5°.

[0067] In actual operation, when the highest point of the arc structure of the hook-shaped part of the elastic arm 310 abuts against the locking pin 500, the elastic arm 310 and the locking pin 500 are in perpendicular contact. The elastic arm 310 does not deform when the door 200 is closed. At this time, an external force greater than 25N must be applied to unlock the elastic arm 310 and the locking pin 500.

[0068] When the inner arc structure of the hook-shaped part of the elastic arm 310 abuts against the locking pin 500, the elastic arm 310 undergoes outward expansion deformation when the door 200 is closed. The larger the angle between the normal of the elastic arm 310 at the linear target position and the normal of the locking pin 500 at the linear target position, the greater the deformation of the elastic arm 310. At this time, unlocking the elastic arm 310 and the locking pin 500 requires an external force greater than 25N. However, if the elastic arm 310 is in a state of large deformation for a long time, it is prone to breakage, resulting in the failure of abutment against the locking pin 500.

[0069] When the outer arc structure of the hook-shaped part of the elastic arm 310 abuts against the locking pin 500, the elastic arm 310 deforms inward in the closed state of the door 200. The larger the angle between the normal of the elastic arm 310 at the linear target position and the normal of the locking pin 500 at the linear target position, the greater the deformation of the elastic arm 310. When α increases to a certain angle, the top of the locking pin 500 directly contacts the lower end face of the elastic arm 310. At this time, the abutment between the elastic arm 310 and the locking pin 500 fails. Pulling the handle 210 to apply an external force to the door 200 that is greater than the frictional force between the top of the locking pin 500 and the lower end face of the elastic arm 310, and greater than the locking force between the door hook and the slot, can open the door 200. However, the frictional force between the top of the locking pin 500 and the lower end face of the elastic arm 310, and the locking force between the door hook and the slot can both be less than 25N. Therefore, children can open cooking utensils more easily in some situations.

[0070] The cooking appliance provided in this application embodiment, by setting the angle between the normal of the elastic arm 310 at the linear target position and the normal of the locking pin 500 at the linear target position to less than 5°, can ensure that unlocking the elastic arm 310 and the locking pin 500 requires an external force greater than 25N. At the same time, it can prevent the elastic arm 310 from breaking under long-term large deformation, which would lead to the failure of the locking pin 500, thereby further improving the safety of the cooking appliance.

[0071] In some embodiments, such as Figure 1 As shown, the door body 200 is pivotally mounted on the host 100, the pivot axis of the door body 200 is located at the lower part of the door body 200, and the elastic clip 300 and the locking pin 500 are located at the top of the door body 200 and the host 100, respectively.

[0072] like Figure 1As shown, the door 200 can be a pull-down door 200. A rotating pin is installed at the lower end of the door 200. The rotating pin is pivotally connected to the lower front side of the main unit 100. That is, the door 200 can rotate downward or upward relative to the main unit 100 around the rotating pin to open or close the cooking cavity.

[0073] like Figure 1 As shown, the main unit 100 is provided with a flexible arm 310 at its upper end, and a locking pin 500 is provided at the upper end of the door body 200 at a position corresponding to the flexible arm 310. The flexible arm 310 extends from the upper end of the main unit 100 toward the door body 200.

[0074] In actual implementation, such as Figure 2 and Figure 4 As shown, when the door 200 is in the closed state, the locking pin 500 is located inside the elastic arm 310. At this time, the hook-shaped part of the elastic arm 310 abuts against the front end face of the locking pin 500, and the hook end of the door hook is located in the slot and engages with the slot for limitation.

[0075] like Figure 5 As shown, when the door 200 needs to be opened, the elastic arm 310 is pulled upward. One end of the elastic arm 310 with a hook-shaped portion begins to lift upward under an external force greater than 25N, while the other end of the elastic arm 310 remains stationary, so that the hook-shaped portion of the elastic arm 310 separates from the front end face of the locking pin 500, raising the hook-shaped portion of the elastic arm 310 to above the locking pin 500 or in contact with the top of the locking pin 500. Since the hook-shaped portion at the front end of the elastic arm 310 has a partial rearward displacement during the upward lifting process, and the elastic element 320 is connected to the hook-shaped portion of the elastic arm 310, the elastic element 320 is in a compressed state during the lifting of the hook-shaped portion of the elastic arm 310.

[0076] Pulling handle 210 applies an external force to both handle 210 and door 200 towards the front of door 200. Under this force, the locking pin 500 tends to move outwards from the elastic arm 310. If the hook-shaped portion of the elastic arm 310 is positioned above the locking pin 500, the first lock formed by the elastic arm 310 and the locking pin 500 is fully open. Continuing to pull door 200 causes it to rotate downwards around the pivot pin, applying an upward thrust to the hook of the door hook within the guide slope of the slot. This causes the hook to move upwards and gradually disengage from the slot, thus opening the door. If the second lock formed by the slot and the door hook is in the open state, food can be placed or taken out into the cooking cavity. If the hook-shaped part of the elastic arm 310 contacts the top of the locking pin 500, the locking pin 500 will exert an external force on the hook-shaped part of the elastic arm 310 under the action of pulling the handle 210, so that it can lift upward. Under this force, the end of the elastic arm 310 with the hook-shaped part will gradually lift upward, and the locking pin 500 will gradually move to the outside of the elastic arm 310 until the two are completely separated and the fully open state is reached. Then the handle 210 can be pulled to unlock the door hook and the slot.

[0077] When the elastic arm 310 is unlocked from the locking pin 500, the elastic arm 310 is released to remove the external force applied to the elastic arm 310, and the end of the elastic arm 310 with the hook-shaped portion is reset under the action of the forward elastic force of the elastic member 320.

[0078] like Figure 6 As shown, when the door 200 needs to be closed, the door 200 is pushed to rotate upward around the pivot pin until the top of the locking pin 500 abuts against the outer side of the hook-shaped part of the elastic arm 310. Under the external force of the locking pin 500, the hook-shaped part of the elastic arm 310 bends and deforms inward. During the deformation process, the hook-shaped part of the elastic arm 310 drives the elastic element 320 to be in a compressed state. The deformed hook-shaped part allows the locking pin 500 to pass under the hook-shaped part of the elastic arm 310 and be located inside the elastic arm 310. When the locking pin 500 is completely inside the elastic arm 310, the external force that the locking pin 500 gave to the elastic arm 310 to deform the hook-shaped part is removed. At this time, the hook-shaped part of the elastic arm 310 is reset under the elastic force of the elastic element 320, and the hook-shaped part of the elastic arm 310 abuts against the front end face of the locking pin 500 to close the first lock. At the same time, the door hook and the slot also engage to close the second lock.

[0079] The cooking appliance provided in this application embodiment, by setting a pull-down door 200 and setting a locking pin 500 and an elastic arm 310 at the top of the cooking appliance, makes it easy for users to take food out of the cooking cavity, and at the same time makes it easy to lock the door 200 and the main unit 100.

[0080] In some embodiments, such as Figure 1As shown, the main unit 100 includes an inner pot and an outer cover. The inner pot has a cooking cavity, and the outer cover is installed outside the inner pot. The door 200 includes a door frame and a door shell. The door shell is installed on the outside of the door frame. The elastic clip 300 and the locking pin 500 are located on the door shell and the outer cover, respectively.

[0081] The outer cover can be a rectangular structure or other shapes with a flat bottom. The inner liner is installed inside the outer cover. The outer cover can be made of heat-insulating material. The elastic arm 310 is installed at the top of the outer cover.

[0082] The door shell can be installed on the outside of the door frame. The connection between the door frame and the door shell can be, but is not limited to, bolt connection, pin connection or snap-fit ​​connection. For example, in some embodiments, the connection between the door frame and the door shell is a bolt connection, and the locking pin 500 is installed on the top of the door shell.

[0083] The cooking appliance provided in this application embodiment can improve the overall strength and heat insulation performance of the cooking appliance by setting an inner pot and an outer cover, so as to avoid the user being burned by the excessive temperature of the cooking appliance when cooking food. By setting a door frame and a door shell, the overall structural design is simple and the connection method is flexible and smooth, which improves the user's sense of use and experience.

[0084] In some embodiments, such as Figures 2-6 As shown, the elastic clamp 300 includes a base 410, an elastic arm 310, and an elastic element 320. The base 410 is connected to one of the main unit 100 and the door body 200. One end of the elastic arm 310 is connected to the base 410, and the other end is used to stop the locking pin 500. The elastic element 320 is connected to the elastic arm 310.

[0085] Among them, such as Figures 2-6 As shown, the base 410 can be connected to the upper end of the host 100, the locking pin 500 can be connected to the upper end of the door 200, the end of the elastic arm 310 near the rear side of the host 100 is connected to the base 410, and the end of the elastic arm 310 near the front side of the host 100 has a hook-shaped part, that is, the end of the elastic arm 310 near the front side of the host 100 is used to stop the locking pin 500, and the two ends of the elastic member 320 are respectively connected to the two ends of the elastic arm 310.

[0086] like Figures 2-6 As shown, the base 410 is provided with a first mounting hole 400. The base 410 is installed on the upper end of the host 100 by threaded connectors such as bolts or screws passing through the first mounting hole 400. The locking pin 500 is also provided with a second mounting hole 420. The locking pin 500 is installed on the upper end of the door 200 by threaded connectors such as bolts or screws passing through the second mounting hole 420.

[0087] By setting the base 410, the connection stability between the elastic arm 310, the elastic element 320 and the host 100 or the door 200 can be improved, thereby improving the locking stability of the elastic clamp 300 and the locking pin 500.

[0088] In some embodiments, such as Figures 2-6 As shown, the elastic arm 310 includes a first segment 330, a second segment 340 and a third segment 350 connected in sequence. The first segment 330 is connected to the base 410. Both the first segment 330 and the third segment 350 are bent from the second segment 340. The free end of the third segment 350 is used for the stop locking pin 500.

[0089] like Figures 2-6 As shown, the elastic arm 310 includes a first segment 330, a second segment 340 and a third segment 350 connected sequentially from back to front. The first segment 330 can be a rectangular structure, or a circular or other shape structure. The bottom of the first segment 330 is connected to the base 410.

[0090] like Figures 2-6 As shown, the second segment 340 can be a W-shaped structure, and both ends of the W are connected to rectangular structures arranged in the horizontal direction. That is, the rectangular structure, the W-shaped structure and the rectangular structure are arranged sequentially from back to front to form the second segment 340. The rectangular structure of the second segment 340 near the rear is connected to the upper end of the first segment 330, and the included angle between the first segment 330 and the second segment 340 can be 90°.

[0091] like Figures 2-6 As shown, the third segment 350 can also be a rectangular structure. The upper end of the third segment 350 is connected to the rectangular structure of the second segment 340 near the front, and the included angle between the second segment 340 and the third segment 350 can be 90°. The lower end of the third segment 350 is bent inward to form a hook-shaped part, which is the free end of the third segment 350.

[0092] In actual operation, when it is necessary to unlock the elastic clip 300 and the locking pin 500, one finger can be used to press against the first segment 330 of the elastic arm 310, and another finger can be used to lift the third segment 350 of the elastic arm 310 upwards. During the lifting process, the front part of the W-shaped structure of the second segment 340 of the elastic arm 310, the rectangular structure near the front of the second segment 340, and the entire third segment 350 rotate backwards around the axis of the lowest part of the front of the W-shaped structure of the second segment 340, while the rest of the parts remain stationary. After successful unlocking, the front part of the W-shaped structure of the second segment 340 of the elastic arm 310, the rectangular structure near the front of the second segment 340, and the entire third segment 350 rotate forward and reset under the elastic force of the elastic element 320.

[0093] The cooking appliance provided in this application embodiment, through the above-mentioned setting of the elastic arm 310, can cause only the front side of the elastic arm 310 to deform significantly during the unlocking process, while the rear side of the elastic arm 310 remains basically still, thereby avoiding the overall rotation of the elastic arm 310, which could lead to incomplete reset or misalignment during reset.

[0094] In some embodiments, the inner side of the second segment 340 is provided with at least two mounting grooves, and the two ends of the elastic member 320 are respectively embedded in the two mounting grooves.

[0095] Among them, such as Figures 2-6 As shown, the shape of the elastic element 320 is roughly the same as the shape of the second segment 340 of the elastic arm 310, and the elastic element 320 has horizontally arranged parts on both the front and rear sides.

[0096] The side of the rectangular structure on the front and rear sides of the second segment 340 of the elastic arm 310 can be provided with a mounting groove. The width of the mounting groove is slightly greater than or equal to the width or diameter of the elastic element 320. The horizontally arranged parts on the front and rear sides of the elastic element 320 are respectively embedded in the two mounting grooves.

[0097] In actual operation, when the elastic arm 310 is raised, causing the elastic element 320 to be compressed, the horizontally positioned part at the front of the elastic element 320 is compressed and deformed along the length of the mounting groove. The front section of the W-shaped part in the middle of the elastic element 320 is compressed, the lowest point of the front of the W-shaped part of the elastic element 320 is elongated and deformed, and the rest remains basically unchanged.

[0098] The cooking appliance provided in this application embodiment can limit the deformation direction of the end of the elastic member 320 by embedding the two ends of the elastic member 320 into two mounting slots respectively, so as to avoid the elastic arm 310 failing to reset due to the movement of the elastic member 320.

[0099] In some embodiments, such as Figures 2-6 As shown, the second segment 340 includes an arc-shaped segment, and the elastic element 320 bends in the same direction as the portion directly opposite the arc-shaped segment.

[0100] Among them, such as Figures 2-6 As shown, the highest point of the W-shaped structure of the second segment 340 of the elastic arm 310 is an arc segment, and the highest point of the W-shaped structure in the middle of the elastic member 320 is also an arc segment. Both the arc segment of the elastic arm 310 and the arc segment of the elastic member 320 are upwardly convex arc segments.

[0101] In actual operation, when the front end of the elastic arm 310 is lifted to unlock the elastic arm 310 and the locking pin 500, the front part of the W-shaped structure of the second segment 340 of the elastic arm 310, the rectangular structure near the front of the second segment 340, and the third segment 350 as a whole rotate backward around the axis of the lowest part of the front of the W-shaped structure of the second segment 340. During the rotation, a certain external force will be applied to the arc segment of the elastic arm 310, and each part of the arc segment can decompose the external force.

[0102] If the highest point of the W-shaped structure of the second segment 340 of the elastic arm 310 is a broken line segment, the external force during rotation will be concentrated at the highest point. Therefore, after multiple unlockings, the highest point of the arc segment is prone to breakage. Similarly, the arc segment of the elastic element 320 has the same effect.

[0103] The cooking appliance provided in this application embodiment, by setting the arc segment, can decompose the external force at the highest point in the middle of the W-shaped structure during the unlocking process, thereby extending the service life of the elastic clip 300.

[0104] In some embodiments, such as Figures 2-6 As shown, the outer side of the second segment 340 is provided with two protrusions 370 that are spaced apart from each other.

[0105] Among them, such as Figures 2-6 As shown, the upper end of the rectangular structure on the front and rear sides of the elastic arm 310 is provided with a boss 370. The boss 370 can be a rectangular structure, or a circular or other shape structure.

[0106] In actual operation, the user can place one finger against the rear side of the protrusion 370 near the rear side of the elastic arm 310, and place the other finger on the front side of the protrusion 370 near the front side of the elastic arm 310, and apply external force to the protrusion 370 on the front side so that the protrusion 370 on the front side drives the front end of the elastic arm 310 to rotate backward and lift upward, thereby completing the unlocking operation.

[0107] The cooking appliance provided in this application embodiment can provide a suitable force point for the user by providing two mutually spaced protrusions 370 on the outer side of the second section 340, so that the user can apply external force to the elastic arm 310 to unlock it from the locking pin 500.

[0108] In some embodiments, such as Figures 2-6 As shown, the base 410 includes a base plate 360 ​​and at least two guard plates 380. The base plate 360 ​​is connected to one of the main unit 100 and the door 200, and the base plate 360 ​​is provided with a limiting groove 390, at least a portion of the elastic member 320 is inserted into the limiting groove 390; the guard plate 380 is connected to the base plate 360, and the elastic arm 310 is located between the two guard plates 380.

[0109] Among them, such as Figures 2-6 As shown, the base plate 360 ​​can be a rectangular structure, or a circular or other shape structure. The base plate 360 ​​is installed on the top of the host 100 by bolts or screws and other threaded connectors. The upper surface of the base plate 360 ​​is provided with a limiting groove 390 along the front and rear direction of the host 100. The width of the limiting groove 390 is slightly larger than the width or diameter of the elastic member 320. The middle part of the elastic member 320 is embedded in the limiting groove 390.

[0110] like Figure 2 As shown, two guard plates 380 can be spaced apart on the upper surface of the base plate 360 ​​along the left and right direction of the host 100. The shape of the upper surface of the guard plate 380 is the same as the shape of the second section 340 of the elastic arm 310. The second section 340 of the elastic arm 310 is installed between the two guard plates 380, and the upper surface of the guard plate 380 after installation is flush with the upper surface of the second section 340 of the elastic arm 310.

[0111] The cooking appliance provided in this application embodiment, through the setting of the base plate 360 ​​and the guard plate 380, can use the limiting groove 390 to limit the middle part of the elastic member 320, so as to prevent the elastic member 320 from deforming in other directions and thus failing to reset the elastic arm 310. At the same time, the guard plate 380 can cover the elastic member 320 to maintain the overall aesthetics and neatness of the elastic clamp 300.

[0112] In some embodiments, such as Figure 4 and Figure 1 As shown, when the door 200 is closed, the front surface of the locking pin 500 abuts against the elastic clamp 300, and the front surface of the locking pin 500 is parallel to the front surface of the door 200.

[0113] The front surface of the door 200 can be set to tilt backward, and the entire locking pin 500 can also be set to tilt backward.

[0114] In actual operation, when closing the door 200, push the door 200 to make the door 200 and the locking pin 500 rotate upward around the rotating pin. When the locking pin 500 contacts the lower end face of the hook-shaped part of the elastic arm 310, the locking pin 500 applies an external force to the lower end face of the hook-shaped part of the elastic arm 310 tilting upward to the rear. The external force on the hook-shaped part of the elastic arm 310 can be divided into a vertically upward component and a horizontally backward component. Under the action of the vertically upward component, the hook-shaped part of the elastic arm 310 bends and deforms inward, and at the same time, under the action of the horizontally backward component, it moves backward for a period of time. Continue to push the door 200 until the locking pin 500 and the elastic arm 310 are locked.

[0115] If the locking pin 500 is in a vertical position, when the door 200 is closed, pushing the door 200 will cause the door 200 and the locking pin 500 to rotate upward around the pivot pin. When the locking pin 500 contacts the lower end face of the hook-shaped part of the elastic arm 310, the locking pin 500 will exert a vertically upward external force on the lower end face of the hook-shaped part of the elastic arm 310. Under the action of the external force, the hook-shaped part of the elastic arm 310 will bend and deform inward. That is, the external force exerted by the locking pin 500 on the hook-shaped part of the elastic arm 310 will be used entirely to bend and deform the hook-shaped part of the elastic arm 310 inward. At this time, the degree of deformation of the hook-shaped part of the elastic arm 310 is greater than the degree of deformation when the locking pin 500 is in an inclined state.

[0116] The cooking appliance provided in this application embodiment, by setting the locking pin 500 to an inclined state, can reduce the degree of deformation of the elastic arm 310 while ensuring that the locking pin 500 can be smoothly locked with the elastic arm 310. This avoids the elastic arm 310 from breaking or being damaged after multiple large deformations, thus extending the service life of the elastic arm 310 and further improving the safety and reliability of the cooking appliance.

[0117] The embodiments of this application will be described in detail below.

[0120] like Figures 2-6 As shown, the elastic clip 300 is installed on the top of the main unit 100. The elastic clip 300 includes an elastic arm 310, an elastic element 320, a base plate 360, and a guard plate 380. The base plate 360 ​​is installed on the top of the main unit 100 through a threaded connector. The guard plate 380 is spaced on the base plate 360 ​​along the left and right directions of the main unit 100. A limiting groove 390 is provided on the upper surface of the base plate 360 ​​between the two guard plates 380. The bottom of the first segment 330 of the elastic arm 310 is connected to the base plate 360. The top of the first segment 330 is connected to the rear side of the second segment 340 of the elastic arm 310, and the two are bent. The front side of the second segment 340 is connected to the top of the third segment 350 of the elastic arm 310, and the two are bent. The lower end of the third segment 350 is bent inward to form a hook shape, and is locked with the locking pin 500 through the hook shape.

[0121] likeFigures 3-6 As shown, the first segment 330 and the third segment 350 of the elastic arm 310 can both be rectangular structures. The second segment 340 is composed of two rectangular structures and a W-shaped structure located between the rectangular structures, and the highest point in the middle of the W-shaped structure is an arc segment.

[0122] like Figures 2-6 As shown, the shape of the elastic element 320 is roughly the same as that of the second section 340 of the elastic arm 310, and the two ends of the elastic element 320 are respectively embedded in the two mounting grooves inside the second section 340 of the elastic arm 310, and the middle part of the elastic element 320 is embedded in the limiting groove 390 of the base plate 360.

[0123] like ​ As shown, the locking pin 500 is installed on the upper end of the door housing through a threaded connector. The locking pin 500 is set to be inclined to the rear, that is, the front surface of the locking pin 500 is set to be inclined to the rear and parallel to the front surface of the door body 200. When the door body 200 is closed, the front surface of the locking pin 500 is in vertical contact with the elastic arm 310.
