Description

Technical Field

[0001] This invention belongs to the technical field of food processing equipment, and more specifically, relates to a lock structure and a cooking utensil. Background Technology

[0002] After cooking, users can directly open the door of the cooking appliance. However, the freshly cooked food is often still very hot, posing a risk of burns. This is especially true when children are using the cooking appliance, increasing the risk of accidents. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] In view of this, in a first aspect, the present invention proposes a lock structure, comprising: a button assembly capable of moving along a first direction; a limiting member disposed on a substrate to be mounted, the limiting member being located on the movement path of the button assembly; and an operating member disposed on the button assembly along the first direction, the operating member and the limiting member being located on opposite sides of the button assembly, the operating member being used to push the button assembly, and the operating member being capable of reciprocating relative to the button assembly along a second direction, the first direction and the second direction being different directions; wherein, when the operating member moves along the second direction to a first position, the limiting member restricts the operating member from pushing the button assembly, and when the operating member is in the second position, the limiting member releases the restriction on the operating member.

[0005] The lock structure provided by this invention is used in cooking appliances, which include a door and a cavity assembly. The operating component, button assembly, and limiting component serve as child locks, which help connect the door and cavity assembly.

[0006] Cooking appliances typically feature interlocking components and latches. The interlocking component disengages the latch from the engagement point on the cavity assembly. Without a child lock, the cavity assembly can be opened by pulling the door. Adding a child lock allows the user to press an operating element, which moves a button assembly. When the button assembly pushes against the interlocking component, it moves the latch. When the door closes the cooking cavity, the latch engages with the cavity assembly. In the first position, a limiting element restricts movement in a first direction, preventing the button assembly from moving. Before opening the cavity, the operating element must be pushed. In the second position, the limiting element moves the element aside, allowing the user to press the operating element and move the button assembly. This two-step process improves the safety of the cooking appliance.

[0007] Specifically, when the door closes the cavity assembly, the latch engages with the latching position on the cavity assembly, preventing the door from opening without external force. After the button assembly pushes the interlocking assembly, the interlocking assembly pushes the latch relative to the latching position on the cavity assembly, causing the latch to separate from the latching position, thus allowing the cavity assembly to be opened. This invention incorporates a child lock structure on the cooking appliance. When the operating component moves to the first position, a limiting member restricts the operating component from pushing the button assembly, making it difficult for the latch to separate from the latching position on the cavity assembly, thereby keeping the door locked and preventing the cavity assembly from being opened.

[0008] When the button assembly is facing towards or away from the interlocking assembly, it reciprocates along the first direction. Therefore, to push the button assembly, the user needs to push the operating member along the first direction, thus causing the operating member to push the button assembly along the first direction. The operating member is slidably connected to the button assembly, so to push the button assembly via the operating member, it needs to be moved away from the limiting member. Therefore, the user first needs to push the operating member along the second direction to the second position (this is the first step), and then push the operating member along the second direction to push the button assembly (this is the second step). These two steps increase the difficulty of opening the door.

[0009] After cooking, the food inside the cooking cavity remains hot, posing a risk of burns if the user opens the door directly to remove it. Therefore, this invention, with its child lock structure, requires users to perform two steps before opening the cavity component. This serves as a warning to the user and prevents children from accidentally opening the cavity component, significantly improving the safety of the cooking appliance.

[0010] In addition, the cooking utensil according to the above-described technical solution provided by the present invention may also have the following additional technical features:

[0011] In one possible design, when the operating member is in the first position, the limiting member is located on the side of the operating member, and the limiting member restricts the movement of the operating member in the first direction; when the operating member is in the second position, the operating member avoids the limiting member.

[0012] In this design, when the user pushes the operating component in the first direction, the operating component abuts against the limiting component. At this time, the limiting component restricts the movement of the operating component in the first direction, so the operating component cannot push the button assembly, and therefore cannot complete the door opening action.

[0013] When the cavity assembly needs to be opened, the user needs to first drive the operating component to move in the second direction, so that the operating component moves away from the limiting component. The limiting component no longer restricts the movement of the operating component in the first direction, that is, the limiting of the operating component is released. At this time, the user can push the operating component in the second direction. The operating component drives the button assembly to move, so that the interlocking assembly can push the latch to separate from the latching position, and complete the door opening action.

[0014] Of course, in other designs, a limiting hole can also be machined into the limiting member. When the operating member is in the first position, the operating member extends into the limiting hole to limit the operation. Other structures that can achieve the limiting function are also within the scope of protection of this invention and are not specifically limited.

[0015] In one possible design, the operating component includes: an operating part; a plug-in part disposed in the operating part on the side facing the button assembly, the operating part being used to drive the plug-in part to move; a first guide part disposed in the plug-in part, the button assembly having a second guide part, the first guide part and the second guide part cooperating to enable the first guide part to move relative to the second guide part in a second direction.

[0016] In this design, the user can drive the operating part to move, which in turn moves the insertion part. When the operating part is in the first position, the limiting member limits the insertion part. When the operating part is in the second position, the limiting member releases the limiting member from the insertion part. During the movement of the insertion part, the first guide part moves along the second guide part. The first and second guide parts cooperate to guide the insertion part, ensuring that the insertion part can move stably along the preset path and in the second direction, which helps improve the functional stability of the child lock structure.

[0017] For example, the first guide portion can be a cylindrical structure, and the second guide portion is formed in a through hole on the button assembly. The cylindrical structure passes through the through hole and moves along the through hole, thereby realizing the guiding function of the plug-in portion. It should be noted that, in order to ensure the stable guidance of the through hole to the cylindrical structure, when the operating member is in the first position or the second position, the cylindrical structure is always located in the through hole.

[0018] In one possible design, the operating element further includes: a first elastic element, sleeved on the first guide portion or the second guide portion, the first elastic element being used to push the insertion portion to move to the first position.

[0019] In this design, an example is given where the first elastic element is fitted onto the first guide portion. The first elastic element is fitted onto the first guide portion, making it difficult for the first elastic element to separate from the first guide portion, thus ensuring that the first elastic element can stably push the insertion portion.

[0020] The first elastic element is located between the button assembly and the connector. The button assembly limits the first end of the first elastic element. When the connector moves to the second position, the first elastic element is in an elastic deformation state, accumulating elastic potential energy. When the user stops pushing the operating part, the second end of the first elastic element pushes the connector under the elastic force, thereby automatically pushing the connector to the first position. By pushing the connector with the first elastic element, the connector can automatically reset, eliminating the need for the user to push it back, reducing the user's operation steps, lowering the difficulty of using the cooking appliance, and improving the user's convenience in using the cooking appliance.

[0021] Furthermore, by automatically pushing the plug-in part to reset through the first elastic element, the operating part is automatically locked when the user stops pushing the operating part, preventing children from opening the cavity component due to the user forgetting to push the operating part to reset, thus further improving the safety of using cooking utensils.

[0022] In one possible design, the operating component further includes: a friction part disposed on the operating part, and the friction part and the insertion part disposed on opposite sides of the operating part.

[0023] In this design, when the user opens the cavity assembly, the user needs to push the side of the operating part away from the insertion part. To facilitate the user's pushing of the operating part, a friction part is provided on the side of the operating part away from the insertion part. The friction part can increase the surface friction of the operating part, making it easier for the user to push the operating part and reducing the difficulty of the user to drive the operating part.

[0024] For example, the friction part can be a number of protruding structures or a number of strip structures.

[0025] In one possible design, the operating element is detachably connected to the button assembly.

[0026] In this design, the control element and button assembly are separate structures, allowing the control element to be detached from the button assembly. When either the control element or the button assembly is damaged, it can be removed from the button assembly for separate maintenance or replacement. This reduces the difficulty of maintaining the control element and button assembly, improves the convenience of maintaining the cooking appliance, and helps reduce maintenance costs.

[0027] The separate design of the control components and button components also facilitates the processing and assembly of cooking utensils. The control components and button components can be processed separately and then assembled. Compared with the one-piece molding method, this reduces the processing difficulty and cost of the mold.

[0028] In one possible application, a snap-fit ​​is machined into the operating component, and a sliding groove is machined into the button assembly. The snap-fit ​​can engage with the sliding groove, thereby connecting the operating component and the button assembly. Furthermore, the snap-fit ​​needs to be able to slide along the sliding groove to ensure that the operating component can slide relative to the button assembly. The structure of the snap-fit ​​and sliding groove further guides the operating component, improving the stability of the engagement between the operating component and the limiting component.

[0029] In one possible design, the button assembly includes: a bracket, an actuating element slidably connected to the bracket along a second direction; and a pressing part, with the actuating element and the pressing part located on opposite sides of the bracket.

[0030] In this design, the operating element is mounted on a bracket, which supports the operating element, allowing the operating element to slide relative to the bracket. The push-button is mounted on the cavity assembly, and the bracket is mounted on the push-button. When the operating element pushes the bracket, the bracket moves the push-button towards the interlocking assembly, thereby causing the push-button to push the interlocking assembly.

[0031] The button assembly consists of two parts: a support and a pressing part. Therefore, a structure that matches the operating element can be machined on the support, and a structure that matches the cavity assembly can be machined on the pressing part, reducing the machining difficulty of the button assembly.

[0032] In one possible design, the bracket is detachably connected to the push button.

[0033] In this design, the support and the push button are separate structures, allowing the support to be detached from the push button. When the support or the push button is damaged, the support can be removed from the push button, and then the support or the push button can be maintained or replaced separately. This reduces the difficulty of maintaining the support or the push button, improves the convenience of maintaining the cooking appliance, and helps to reduce the maintenance cost of the cooking appliance.

[0034] The separate design of the support and the push button makes it easier to process and assemble the cooking utensils. The support and the push button can be processed separately and then assembled. Compared with the one-piece molding method, this reduces the processing difficulty and cost of the mold.

[0035] In one possible application, a buckle is machined into the bracket, and a slot is machined into the button assembly. The buckle can be engaged into the slot, thereby connecting the bracket and the button.

[0036] In other designs, the bracket and the push button can also be locked using screws or other locking devices.

[0037] In one possible design, the actuating part includes: a body; and a guide post disposed on the body, the guide post being used to guide the body to move along a first direction.

[0038] In this design, the guide post guides the main body, ensuring that the pusher can move stably in the first direction.

[0039] The push part can push the interlocking component. In order to improve the stability of the cooperation between the push part and the interlocking component, a guide part and a guide hole are set to realize the guiding function, so as to avoid misalignment between the push part and the interlocking component, which is conducive to improving the functional stability of the cooking appliance.

[0040] In one possible design, the pusher also includes a second elastic member sleeved on the guide post, the second elastic member being used to push the body to move in a third direction, wherein the third direction is opposite to the direction of the pusher.

[0041] In this design, the second elastic element is sleeved on the guide post, making it difficult for the second elastic element to separate from the guide post, thus ensuring that the second elastic element can stably push the push part.

[0042] The second elastic element is located between the push part and the cavity assembly. The cavity assembly limits the first end of the second elastic element. When the push part pushes the interlocking assembly, the second elastic element is in an elastic deformation state, accumulating elastic potential energy. When the user stops pushing the operating part, the second end of the second elastic element pushes the push part under the elastic force, thereby automatically pushing the push part away from the interlocking assembly. By pushing the push part with the second elastic element, the push part can be automatically reset, eliminating the need for the user to pull the push part to reset. This reduces the user's operating steps, lowers the difficulty of using the cooking appliance, and improves the user's convenience in using the cooking appliance.

[0043] Furthermore, by automatically resetting the plug-in part through the second elastic element, when the user stops pushing the operating part, the plug-in part is ensured to move to the side of the limiting element, thereby automatically locking the operating part and preventing children from opening the cavity component due to the user forgetting to push the operating part to reset, thus further improving the safety of using cooking utensils.

[0044] In one possible design, the support includes: a plate; a support portion disposed on the plate, the support portion having a receiving cavity, a plug-in portion and a first guide portion being received within the receiving cavity, the receiving cavity having an opening, the plug-in portion extending into or out of the receiving cavity through the opening.

[0045] In this design, the supporting part is machined with a receiving cavity, and the insertion part can extend into the receiving cavity, that is, a part of the operating component extends into the receiving cavity. Part of the operating component is exposed in the receiving cavity, thereby reducing the volume of the operating component protruding from the support, reducing the space occupied by the operating component and button assembly, which helps to improve the space utilization inside the cooking appliance and reduce the size of the cooking appliance.

[0046] An opening is provided in the receiving cavity, through which the insertion part can pass, thus avoiding interference from the interior of the receiving cavity with the movement of the insertion part.

[0047] Secondly, the present invention provides a cooking appliance, comprising: a cavity assembly, the cavity assembly including a base plate to be installed; a door body disposed on the cavity assembly; a latch disposed on the door body for opening and closing connection with the cavity assembly; an interlocking assembly disposed on the cavity assembly for driving the latch to separate from the cavity assembly; and a lock structure as described in any of the above technical solutions, wherein a button assembly and a limiting member are disposed on the cavity assembly, and the button assembly pushes the interlocking assembly to move, so that the interlocking assembly drives the latch to move.

[0048] The user can press the operating component, which then moves the button assembly. When the button assembly pushes the interlocking component, the interlocking component moves the latch. When the door closes the cooking cavity, the latch connects to the cavity assembly. When the operating component is in the first position, the limiting component restricts its movement in the first direction, preventing the operating component from pushing the button assembly. Before opening the cavity assembly, the operating component needs to be pushed. When the operating component moves to the second position, the limiting component avoids it, allowing the user to press the operating component and move the button assembly. Opening the cavity assembly requires two steps, which improves the safety of using the cooking appliance.

[0049] Specifically, when the door closes the cavity assembly, the latch engages with the latching position on the cavity assembly, preventing the door from opening without external force. After the button assembly pushes the interlocking assembly, the interlocking assembly pushes the latch relative to the latching position on the cavity assembly, causing the latch to separate from the latching position, thus allowing the cavity assembly to be opened. This invention incorporates a child lock structure on the cooking appliance. When the operating component moves to the first position, a limiting member restricts the operating component from pushing the button assembly, making it difficult for the latch to separate from the latching position on the cavity assembly, thereby keeping the door locked and preventing the cavity assembly from being opened.

[0050] When the button assembly is facing towards or away from the interlocking assembly, it reciprocates along the first direction. Therefore, to push the button assembly, the user needs to push the operating member along the first direction, thus causing the operating member to push the button assembly along the first direction. The operating member is slidably connected to the button assembly, so to push the button assembly via the operating member, it needs to be moved away from the limiting member. Therefore, the user first needs to push the operating member along the second direction to the second position (this is the first step), and then push the operating member along the second direction to push the button assembly (this is the second step). These two steps increase the difficulty of opening the door.

[0051] After cooking, the food inside the cooking cavity remains hot, posing a risk of burns if the user opens the door directly to remove it. Therefore, this invention, with its child lock structure, requires users to perform two steps before opening the cavity component. This serves as a warning to the user and prevents children from accidentally opening the cavity component, significantly improving the safety of the cooking appliance.

[0052] In the above technical solution, the interlocking component includes: a flap, which is rotatably connected to the cavity component, and the button component can push the flap to rotate; and a lever, which is rotatably connected to the cavity component, and the flap is used to push the lever to rotate so that the lever pushes the latch to disengage from the cavity component.

[0053] In this technical solution, both the flap and the lever are rotatably connected to the cavity assembly. When the button assembly pushes the flap, the flap rotates relative to the cavity assembly. The rotating flap pushes the lever, causing the lever to rotate relative to the cavity assembly. When the lever rotates, it can push the latch, causing the latch to separate from the engagement position.

[0054] In the above technical solution, the cavity assembly includes: a cavity body; a control panel located in the cavity body; and a locking structure located in the control panel.

[0055] In this technical solution, the lock structure is placed on the control panel, allowing users to press the operating components from the front of the cooking appliance, making it convenient for users to operate.

[0056] In the above technical solution, the first side of the control panel is provided with a mounting cavity, and the button assembly is located inside the mounting cavity.

[0057] In this technical solution, the button assembly is housed within the mounting cavity, so that the button assembly does not protrude from the surface of the control panel, or only a small portion of the button assembly protrudes from the control panel. This not only improves the appearance of the cooking appliance but also prevents scratches to the user.

[0058] In the above technical solution, the control panel is provided with a limiting groove, and a part of the limiting member passes through the limiting groove from the second side of the control panel. The first side and the second side of the control panel are opposite sides of the control panel. The cooking appliance also includes a locking member, which locks the limiting member to the control panel.

[0059] In this technical solution, the limiting groove plays a limiting role for the limiting component, making it difficult for the limiting component to separate from the control panel. This improves the installation stability of the limiting component and the control panel, and enables the limiting component to stably limit the operation component.

[0060] In the above technical solution, the control panel is provided with a guide hole, and the guide post in the button assembly passes through the guide hole.

[0061] In this technical solution, the guide hole guides the guide post, ensuring that the pressing part can move stably along the first direction.

[0062] In the above technical solution, the button assembly has a snap-fit ​​part, and the control panel has a snap-fit ​​hole, with the snap-fit ​​part snapping into the snap-fit ​​hole.

[0063] In this technical solution, the button assembly and the control panel are separate structures, allowing the button assembly to be detached and installed on the control panel. When the button assembly is damaged, it can be removed from the control panel for separate maintenance or replacement. This reduces the difficulty and convenience of maintaining cooking appliances, and also lowers maintenance costs.

Detailed Implementation

[0078] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0079] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0080] The following reference Figures 1 to 10 This invention describes a lock structure and a cooking appliance provided according to some embodiments of the invention.

[0081] Combination Figure 1 , Figure 2 and Figure 3As shown, in some embodiments of the present invention, a lock structure is proposed, including: a button assembly 500, a limiting member 600, and an operating member 700. The button assembly 500 is movable along a first direction; the limiting member 600 is disposed on the substrate to be installed and is located on the movement path of the button assembly 500; the operating member 700 is disposed on the button assembly 500 along the first direction, and the operating member 700 and the limiting member 600 are located on both sides of the button assembly 500. The operating member 700 is used to push the button assembly 500, and the operating member 700 is capable of reciprocating relative to the button assembly 500 along a second direction, wherein the first direction and the second direction are different directions; wherein, when the operating member 700 moves to a first position along the second direction, the limiting member 600 restricts the operating member 700 from pushing the button assembly 500, and when the operating member 700 is in a second position, the limiting member 600 releases the restriction on the operating member 700.

[0082] The cooking appliance provided in this embodiment is used as a cooking appliance. The cooking appliance includes a door 200 and a cavity assembly 100. The operating component 700, the button assembly 500, and the limiting component 600 serve as child locks and also play an auxiliary role in connecting the door 200 and the cavity assembly 100.

[0083] Cooking appliances typically include an interlocking component 400 and a latch 300. The interlocking component 400 can disengage the latch 300 from the engagement position on the cavity component 100. When the cavity component 100 does not have a child lock mechanism, the user can open the cavity component 100 by pulling the door 200. By adding a child lock mechanism to the cavity component 100, the user can press the operating element 700, which then moves the button component 500. When the button component 500 pushes the interlocking component 400, the interlocking component 400 can move the latch 300. When the door 200 closes the cooking cavity, the latch 300 is connected to the cavity component 100. When the operating element 700 is in the first position, the limiting element 600 restricts the movement of the operating element 700 in the first direction, at which point the operating element 700 cannot push the button component 500. Before opening the cavity assembly 100, the operating component 700 needs to be moved. When the operating component 700 moves to the second position, the limiting component 600 avoids the operating component 700. At this time, the user can press the operating component 700 and move the button assembly 500. Opening the cavity assembly 100 requires two steps, which helps to improve the safety of using the cooking appliance.

[0084] Specifically, when the door 200 closes the cavity assembly 100, the latch 300 engages with the latching position on the cavity assembly 100, preventing the door 200 from opening the cavity assembly 100 without external force. After the button assembly 500 pushes the interlocking assembly 400, the interlocking assembly 400 pushes the latch 300 to move relative to the latching position on the cavity assembly 100, causing the latch 300 to separate from the latching position, thereby allowing the cavity assembly 100 to be opened. In this invention, a child lock structure is added to the cooking appliance. When the operating member 700 moves to the first position, the limiting member 600 restricts the operating member 700 from pushing the button assembly 500, making it difficult for the latch 300 to separate from the latching position on the cavity assembly 100, thus keeping the door 200 in a locked state and preventing the cavity assembly 100 from being opened.

[0085] When the button assembly 500 is facing or moving away from the interlocking assembly 400, the button assembly 500 reciprocates along the first direction. Therefore, in order to push the button assembly 500, the user needs to push the operating member 700 along the first direction, thereby causing the operating member 700 to push the button assembly 500 along the first direction. The operating member 700 is slidably connected to the button assembly 500, so in order to push the button assembly 500 through the operating member 700, the operating member 700 needs to be moved away from the limiting member 600. Therefore, the user needs to first push the operating member 700 along the second direction to move it to the second position, which is the first step, and then push the operating member 700 along the second direction to push the button assembly 500, which is the second step. These two steps increase the difficulty of opening the door.

[0086] After the cooking process is complete, the food inside the cooking cavity remains hot. If a user directly opens the door 200 to remove the food at this point, there is a risk of burns. Therefore, this invention, through the aforementioned child lock structure, requires the user to perform two steps before opening the cavity assembly 100. This serves as a reminder to the user and prevents children from accidentally opening the cavity assembly 100, significantly improving the safety of the cooking appliance.

[0087] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one possible embodiment, when the operating member 700 is in the first position, the limiting member 600 is located on the side of the operating member 700, and the limiting member 600 restricts the operating member 700 from moving in the first direction; when the operating member 700 is in the second position, the operating member 700 avoids the limiting member 600.

[0088] In this embodiment, when the user pushes the operating member 700 in the first direction, the operating member 700 abuts against the limiting member 600. At this time, the limiting member 600 restricts the operation member 700 from moving in the first direction, so the operating member 700 cannot push the button assembly 500, and therefore cannot complete the door opening action.

[0089] When the cavity assembly 100 needs to be opened, the user needs to first drive the operating member 700 to move in the second direction, so that the operating member 700 moves away from the limiting member 600. The limiting member 600 no longer restricts the movement of the operating member 700 in the first direction, that is, the limiting of the operating member 700 is released. At this time, the user can push the operating member 700 in the second direction. The operating member 700 drives the button assembly 500 to move, so that the interlocking assembly 400 can push the latch 300 to separate from the latching position, thus completing the door opening action.

[0090] Of course, in other embodiments, a limiting hole can also be formed in the limiting member 600. When the operating member 700 is in the first position, the operating member 700 extends into the limiting hole to limit the operation member 700. Other structures that can achieve the limiting function are also within the protection scope of this invention and are not specifically limited.

[0091] Combination Figure 5 , Figure 6 and Figure 7 As shown, in one possible embodiment, the operating member 700 includes: an operating part 710, a plug-in part 720, and a first guide part 730. The plug-in part 720 is disposed in the operating part 710 on the side facing the button assembly 500, and the operating part 710 is used to drive the plug-in part 720 to move. The first guide part 730 is disposed in the plug-in part 720, and the button assembly 500 is provided with a second guide part 510. The first guide part 730 and the second guide part 510 cooperate with each other so that the first guide part 730 can move relative to the second guide part 510 in a second direction.

[0092] In this embodiment, the user can drive the operating unit 710 to move, causing the operating unit 710 to move the insertion part 720. When the operating member 700 is in the first position, the limiting member 600 limits the insertion part 720. When the operating member 700 is in the second position, the limiting member 600 releases the limiting of the insertion part 720. During the movement of the insertion part 720, the first guide part 730 moves along the second guide part 510. The first guide part 730 and the second guide part 510 cooperate with each other to guide the insertion part 720, ensuring that the insertion part 720 can move stably along the preset path and in the second direction, which helps to improve the functional stability of the child lock structure.

[0093] For example, the first guide portion 730 can be a cylindrical structure, and the second guide portion 510 is formed in a through hole on the button assembly 500. The cylindrical structure passes through the through hole and moves along the through hole, thereby realizing the guiding function of the plug-in portion 720. It should be noted that in order to ensure the stable guidance of the through hole to the cylindrical structure, when the operating member 700 is in the first position or the second position, the cylindrical structure is always located in the through hole.

[0094] Combination Figure 5 and Figure 6 As shown, in one possible embodiment, the operating member 700 further includes a first elastic member 740, which is sleeved on the first guide portion 730 or the second guide portion 510, and is used to push the insertion portion 720 to move to the first position.

[0095] In this embodiment, the first elastic member 740 is sleeved on the first guide portion 730 as an example. The first elastic member 740 is sleeved on the first guide portion 730, making it difficult for the first elastic member 740 to separate from the first guide portion 730, thus ensuring that the first elastic member 740 can stably push the insertion portion 720.

[0096] The first elastic element 740 is located between the button assembly 500 and the plug-in portion 720. The button assembly 500 limits the first end of the first elastic element 740. When the plug-in portion 720 moves to the second position, the first elastic element 740 is in an elastic deformation state, at which time the first elastic element 740 accumulates elastic potential energy. When the user stops pushing the operation part 710, under the elastic force of the first elastic element 740, the second end of the first elastic element 740 pushes the plug-in portion 720, thereby automatically pushing the plug-in portion 720 to the first position. By pushing the plug-in portion 720 with the first elastic element 740, the plug-in portion 720 can be automatically reset, eliminating the need for the user to push the plug-in portion 720 to reset, reducing the user's operation steps, lowering the difficulty of using the cooking appliance, and improving the user's convenience in using the cooking appliance.

[0097] Furthermore, by automatically pushing the plug-in part 720 to reset via the first elastic element 740, the operating part 700 is automatically locked when the user stops pushing the operating part 710, thus preventing children from opening the cavity assembly 100 due to the user forgetting to push the operating part 700 to reset, and further improving the safety of using cooking utensils.

[0098] Combination Figure 5 and Figure 6 As shown, in one possible embodiment, the operating member 700 further includes a friction part 750, which is disposed on the operating part 710, and the friction part 750 and the insertion part 720 are disposed on opposite sides of the operating part 710.

[0099] In this embodiment, when the user opens the cavity assembly 100, the user needs to push the side of the operation unit 710 away from the insertion part 720. To facilitate the user's pushing of the operation unit 710, a friction part 750 is provided on the side of the operation unit 710 away from the insertion part 720. The friction part 750 can increase the surface friction of the operation unit 710, making it easier for the user to push the operation unit 710 and reducing the difficulty of driving the operation unit 710.

[0100] For example, the friction part 750 can be a plurality of protruding structures or a plurality of strip structures.

[0101] In one possible embodiment, the operating element 700 is detachably connected to the button assembly 500.

[0102] In this embodiment, the operating component 700 and the button assembly 500 are separate structures, allowing the operating component 700 to be detached from the button assembly 500. When either the operating component 700 or the button assembly 500 is damaged, the operating component 700 can be disassembled from the button assembly 500, and then either the operating component 700 or the button assembly 500 can be maintained or replaced separately. This reduces the difficulty of maintaining the operating component 700 and the button assembly 500, improves the convenience of maintaining the cooking appliance, and helps reduce the maintenance cost of the cooking appliance.

[0103] The separate design of the control component 700 and the button assembly 500 also facilitates the processing and assembly of the cooking appliance. The control component 700 and the button assembly 500 can be processed separately and then assembled. Compared with the one-piece molding method, this reduces the processing difficulty and cost of the mold.

[0104] In one possible application, a snap-fit ​​is machined into the operating element 700, and a sliding groove is machined into the button assembly 500. The snap-fit ​​can engage with the sliding groove, thereby connecting the operating element 700 and the button assembly 500. Furthermore, the snap-fit ​​needs to be able to slide along the sliding groove to ensure that the operating element 700 can slide relative to the button assembly 500. The structure of the snap-fit ​​and sliding groove further guides the operating element 700, improving the stability of the engagement between the operating element 700 and the limiting element 600.

[0105] Combination Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, in one possible embodiment, the button assembly 500 includes: a bracket 520 and a pressing part 530, and an operating member 700 is slidably connected to the bracket 520 along a second direction; the bracket 520 is disposed on the pressing part 530, and the operating member 700 and the pressing part 530 are located on both sides of the bracket 520.

[0106] In this embodiment, the operating member 700 is mounted on the bracket 520, which supports the operating member 700, and the operating member 700 is slidable relative to the bracket 520. The push part 530 is mounted on the cavity assembly 100, and the bracket 520 is mounted on the push part 530. When the operating member 700 pushes the bracket 520, the bracket 520 causes the push part 530 to move towards the interlocking assembly 400, thereby pushing the interlocking assembly 400.

[0107] The button assembly 500 consists of two parts: a bracket 520 and a pressing part 530. Therefore, a structure that cooperates with the operating member 700 can be machined on the bracket 520, and a structure that cooperates with the cavity assembly 100 can be machined on the pressing part 530, reducing the processing difficulty of the button assembly 500.

[0108] In one possible embodiment, the bracket 520 is detachably connected to the push part 530.

[0109] In this embodiment, the support 520 and the push button 530 are separate structures, allowing the support 520 to be detached from the push button 530. When either the support 520 or the push button 530 is damaged, the support 520 can be removed from the push button 530, and then the support 520 or the push button 530 can be maintained or replaced separately. This reduces the difficulty of maintaining the support 520 or the push button 530, improves the convenience of maintaining the cooking appliance, and helps reduce the maintenance cost of the cooking appliance.

[0110] The separate design of the support 520 and the push button 530 also facilitates the processing and assembly of cooking utensils. The support 520 and the push button 530 can be processed separately and then assembled. Compared with the one-piece molding method, this reduces the processing difficulty and cost of the mold.

[0111] In one possible application, a buckle is formed on the bracket 520 and a slot is formed on the button assembly 500. The buckle can be engaged into the slot, thereby connecting the bracket 520 and the button 530.

[0112] In other embodiments, the bracket 520 and the push part 530 can also be locked by locking devices such as screws.

[0113] Combination Figure 3 , Figure 8 and Figure 9 As shown, in one possible embodiment, the push part 530 includes: a body 531 and a guide post 532, the guide post 532 being disposed on the body 531 and used to guide the body 531 to move along a first direction.

[0114] In this embodiment, the guide post 532 guides the push part 530, ensuring that the push part 530 can move stably along the first direction.

[0115] The push part 530 can push the interlocking component 400. In order to improve the stability of the cooperation between the push part 530 and the interlocking component 400, a guide part and a guide hole are provided to realize the guiding function, so as to avoid misalignment between the push part 530 and the interlocking component 400, which is conducive to improving the functional stability of the cooking appliance.

[0116] Combination Figure 3 and Figure 9 As shown, in one possible embodiment, the push part 530 further includes a second elastic member 533, which is sleeved on the guide post 532. The second elastic member 533 is used to push the body 531 to move in a third direction, wherein the third direction is opposite to the direction of the push operation member 700.

[0117] In this embodiment, the second elastic member 533 is sleeved on the guide post 532, making it difficult for the second elastic member 533 to separate from the guide post 532, thus ensuring that the second elastic member 533 can stably push the push part 530.

[0118] The second elastic element 533 is located between the push part 530 and the cavity assembly 100. The cavity assembly 100 limits the first end of the second elastic element 533. When the push part 530 pushes the interlocking assembly 400, the second elastic element 533 is in an elastic deformation state, at which time the second elastic element 533 accumulates elastic potential energy. When the user stops pushing the operating part 710, under the elastic force of the second elastic element 533, the second end of the second elastic element 533 pushes the push part 530, thereby automatically pushing the push part 530 away from the interlocking assembly 400. By pushing the push part 533 with the second elastic element 533, the push part 530 can be automatically reset, eliminating the need for the user to pull the push part 530 to reset, reducing the user's operation steps, lowering the difficulty of using the cooking appliance, and improving the user's convenience in using the cooking appliance.

[0119] Furthermore, by automatically pressing the plug 720 to reset via the second elastic element 533, when the user stops pushing the operation part 710, the plug 720 is ensured to move to the side of the limit member 600, thereby automatically locking the operation part 700. This prevents children from opening the cavity assembly 100 due to the user forgetting to push the operation part 700 to reset, further enhancing the safety of using cooking utensils.

[0120] Combination Figure 3 and Figure 9As shown, in one possible embodiment, the bracket 520 includes: a plate 521 and a support portion 522. The support portion 522 is disposed on the plate 521 and has a receiving cavity 524. The insertion portion 720 and the first guide portion 730 are received in the receiving cavity 524. The receiving cavity 524 has an opening 525, and the insertion portion 720 extends into or out of the receiving cavity 524 through the opening 525.

[0121] In this embodiment, a receiving cavity 524 is machined into the support portion 522, and the insertion portion 720 can extend into the receiving cavity 524, that is, a part of the operating member 700 extends into the receiving cavity 524. Part of the operating member 700 protrudes from the receiving cavity 524, thereby reducing the volume of the operating member 700 extending out of the support 520, reducing the space occupied by the operating member 700 and the button assembly 500, which is beneficial for improving the space utilization inside the cooking appliance and reducing the size of the cooking appliance.

[0122] An opening 525 is provided in the receiving cavity 524, through which the insertion part 720 can pass, thereby preventing the interior of the receiving cavity 524 from interfering with the movement of the insertion part 720.

[0123] In some embodiments of the present invention, a cooking appliance is provided, comprising: a cavity assembly 100, a door 200, a latch 300, an interlocking assembly 400, and a locking structure as described in any of the above possible embodiments. The cavity assembly 100 includes the substrate to be installed as described in the above embodiments. The door 200 is disposed on the cavity assembly 100; the latch 300 is disposed on the door 200 and is used for opening and closing connection with the cavity assembly 100; the interlocking assembly 400 is disposed on the cavity assembly 100 and is used to drive the latch 300 to separate from the cavity assembly 100; a button assembly 500 and a limiting member 600 are disposed on the cavity assembly 100, and the button assembly 500 pushes the interlocking assembly 400 to move, so that the interlocking assembly 400 drives the latch 300 to move.

[0124] The user can press the operating element 700, which then moves the button assembly 500. When the button assembly 500 pushes the interlocking assembly 400, the interlocking assembly 400 can move the latch 300. When the door 200 closes the cooking cavity, the latch 300 is connected to the cavity assembly 100. When the operating element 700 is in the first position, the limiting member 600 restricts the operation element 700 from moving in the first direction, and at this time, the operating element 700 cannot push the button assembly 500. Before opening the cavity assembly 100, the operating element 700 needs to be pushed. When the operating element 700 moves to the second position, the limiting member 600 avoids the operation element 700, at which point the user can press the operating element 700 and move the button assembly 500. Opening the cavity assembly 100 requires two steps, which helps improve the safety of using the cooking appliance.

[0125] In one possible embodiment, the interlocking assembly 400 includes: a flap 410 rotatably connected to the cavity assembly 100, and a button assembly 500 capable of pushing the flap 410 to rotate; and a lever 420 rotatably connected to the cavity assembly 100, wherein the flap 410 is used to push the lever 420 to rotate so that the lever 420 pushes the latch 300 to disengage from the cavity assembly 100.

[0126] In this embodiment, both the flap 410 and the lever 420 are rotatably connected to the cavity assembly 100. When the button assembly 500 pushes the flap 410, the flap 410 rotates relative to the cavity assembly 100. The rotating flap 410 pushes the lever 420, causing the lever 420 to rotate relative to the cavity assembly 100. When the lever 420 rotates, it can push the latch 300, causing the latch 300 to separate from the engagement position.

[0127] In one possible embodiment, the cavity assembly 100 includes: a cavity body 120; a control panel 130 disposed on the cavity body 120; and a locking structure disposed on the control panel 130.

[0128] In this embodiment, the lock structure is set on the control panel 130, so that the user can press the operating component 700 from the front of the cooking appliance, which is convenient for the user to operate.

[0129] In one possible embodiment, the first side of the control panel 130 is provided with a mounting cavity 131, and the button assembly 500 is located in the mounting cavity 131.

[0130] In this embodiment, the button assembly 500 is housed in the mounting cavity 131, so that the button assembly 500 does not protrude from the surface of the control panel 130, or only a small part of the button assembly 500 protrudes from the control panel 130. This not only improves the appearance of the cooking appliance, but also avoids scratching the user.

[0131] In one possible embodiment, the control panel 130 is provided with a limiting groove 132, and a portion of the limiting member 600 passes through the limiting groove 132 from the second side of the control panel 130; the cooking appliance also includes a locking member that locks the limiting member 600 to the control panel 130.

[0132] In this embodiment, the limiting groove 132 limits the limiting member 600, making it difficult for the limiting member 600 to separate from the control panel 130, thereby improving the installation stability of the limiting member 600 and the control panel 130, and enabling the limiting member 600 to stably limit the operation member 700.

[0133] In one possible embodiment, the control panel 130 is provided with a guide hole 133, through which the guide post 532 in the button assembly 500 passes.

[0134] In this embodiment, the guide hole 133 guides the guide post 532, ensuring that the push part 530 can move stably along the first direction.

[0135] In one possible embodiment, the push part 530 in the button assembly 500 is provided with a snap-fit ​​part 534, and the control panel 130 is provided with a snap-fit ​​hole 134, and the snap-fit ​​part 534 snaps into the snap-fit ​​hole 134.

[0136] In this embodiment, the button assembly 500 and the control panel 130 are separate structures, allowing the button assembly 500 to be detached from and installed on the control panel 130. When the button assembly 500 is damaged, it can be removed from the control panel 130 for maintenance or replacement, which helps reduce the difficulty and convenience of maintaining the cooking appliance and lowers the maintenance cost.
