Description

Technical Field

[0001] The embodiments of the present invention relate to the field of cooking utensil technology, and more specifically, to a locking component and a cooking utensil. Background Technology

[0002] Currently, in related technologies, microwave ovens include a door and a cabinet. The cabinet has a cooking cavity, and the door has a door hook that can be attached to the cabinet to open or close the cooking cavity. However, because the door can be opened directly under external force, especially for children, if a child opens the door while the appliance is cooking, it could result in burns from the high temperature inside the cooking cavity, posing a safety hazard to the appliance. Summary of the Invention

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

[0004] Therefore, a first aspect of the present invention provides a locking component.

[0005] A second aspect of the present invention provides a cooking utensil.

[0006] In view of the above, a first aspect of the present invention provides a locking assembly for a cooking appliance, the cooking appliance including a door body with a door hook, the locking assembly including a support member, a mating member, a first limiting post, and a limiting member; the mating member is connected to the support member and is rotatable relative to the support member, the mating member is provided with a mating groove, the mating member is in a first position where the door hook can disengage from the mating groove, the mating member is in a second position where the door hook engages with the mating groove; the first limiting post is disposed on the mating member, located on a side away from the rotation axis of the mating member; the limiting member is connected to the support member and has a third position and a fourth position; wherein, in the third position, the limiting member is located on the movement path of the first limiting post and can restrict the mating member from rotating from the second position to the first position; in the fourth position, the limiting member is away from the movement path of the first limiting post and the mating member can move from the second position to the first position.

[0007] The locking assembly provided by this invention includes a support component and a mating component. The mating component is connected to the support component, thereby enabling the installation and fixation of the mating component. The mating component is rotatable relative to the support component, and can rotate from a first position to a second position and from the second position to the first position. The mating component is provided with a mating groove that can engage with a door hook. When the mating component is in the second position and the door hook is located within the mating groove, the door is in a closed state when no external force is received. When the door is pulled by an external force, the door hook pulls the mating component from the second position to the first position, disengaging the door hook and thus opening the door. The mating component is provided with a first limiting post, which rotates together with the mating component when the mating component rotates.

[0008] The locking assembly also includes a limiting member connected to the support component. The limiting member is located in the third position, on the movement path of the first limiting post. When the mating component rotates from the second position to the first position, because the limiting member is on the movement path of the first limiting post, it prevents the first limiting post from continuing to move, thus preventing the mating component from rotating further from the second position to the first position, thereby restricting the rotation of the mating component. Since the mating component cannot rotate to the first position, the door cannot be opened by external force.

[0009] When the limiting member is in the fourth position, its movement path is away from the first limiting post. As the mating member rotates from the second position to the first position, the limiting member's movement path away from the first limiting post ensures that it does not prevent the first limiting post from continuing to move, thus allowing the mating member to rotate from the second position to the first position. After the mating member reaches the first position, the door hook disengages from the mating member, allowing the door to open.

[0010] By controlling the position of the limiting component, the door's opening and closing can be controlled. When the cooking appliance is in the cooking state, driving the limiting component to the third position prevents the door from being opened by external force. Even if a child pulls on the door, it will not open due to the limiting component, reducing the probability of children being burned by the high temperature inside the cooking cavity due to the door opening, minimizing safety hazards associated with the cooking appliance, and improving its safety.

[0011] When the door needs to be opened, the drive limiter moves to the fourth position, so that the door can be opened under the pull of external force, which makes it easier for the operator of the cooking appliance to take out the food being cooked in the cooking cavity, so that the cooking appliance can be used normally.

[0012] By limiting the movement of mating parts through limiting components to restrict the door body, the locking assembly can restrict the door body where the door hook cannot rotate, thus expanding the applicability of the locking assembly.

[0013] Because the first limiting post is located on the side away from the rotation axis of the mating component, the distance between the first limiting post and the rotation axis of the mating component is increased. As a result, the lever arm of the mating component is lengthened during the closing process, and the resistance applied to the first limiting post by the limiting component can be overcome with a smaller pushing force, thus making the closing of the door easier and improving the feel of the door when closing.

[0014] The first limiting post is located on the side away from the rotation axis of the mating part, which also makes the first limiting post move a longer distance during the opening and closing process, further improving the feel of the door when it is closed.

[0015] In addition, the locking component in the above-mentioned technical solution provided by the present invention may also have the following additional technical features:

[0016] In one embodiment of the present invention, the locking component further includes a second limiting post, which is connected to the support component and is located on the side of the limiting component near the first position.

[0017] In this technical solution, the locking component also includes a second limiting post, which is connected to the supporting component, thus supporting and fixing the second limiting post. When the door is pulled, the first limiting post, which is set on the mating component, applies a pushing force from the second position to the first position to the limiting component. Since the second limiting post is located on the side of the limiting component closer to the first position, the second limiting post can support the limiting component, thereby counteracting the pushing force applied to the limiting component by the first limiting post and preventing the limiting component from rotating under the pushing force of the first limiting post. This allows the limiting component to effectively prevent the door from being opened in the third position, thereby improving the safety of the cooking appliance during the cooking process.

[0018] In one technical solution of the present invention, the limiting member is located in the third position and abuts against the second limiting post.

[0019] In this technical solution, when the cooking appliance is in the cooking state, the limiting member is in the third position and abuts against the second limiting post. If the door is subjected to tension, the limiting member can prevent the door from moving, thus preventing gaps from forming between the door and the cooking appliance housing. This prevents high-temperature gas in the cooking cavity from leaking through the gap between the door and the cooking appliance housing, further improving the safety of the cooking appliance during the cooking process.

[0020] In one technical solution of the present invention, the limiting member is located in the third position, and there is a gap between the limiting member and the second limiting post.

[0021] In this technical solution, the limiting member is located in the third position, and there is a gap between the limiting member and the second limiting post. When the cooking appliance is in the cooking state, if the door is subjected to a pulling force, the door can be pulled open by a gap until the first limiting post contacts the limiting member, and the limiting member contacts the second limiting post, at which point the door stops moving. While preventing the door from opening, it ensures that the gap between the door and the cooking appliance housing can control the cooking appliance to stop working, thereby avoiding the leakage of high temperature or microwaves in the cooking cavity through the gap due to continuous operation of the cooking appliance, which could cause injury to the operator of the cooking appliance, and further improving the safety of the cooking appliance during the cooking process.

[0022] Furthermore, by having a gap between the limiting member and the second limiting post, even if the first limiting post, the limiting member, and the second limiting post are worn due to long-term use, the high temperature or microwave inside the cooking cavity can be controlled to stop working, thus avoiding injury to the operator of the cooking appliance. This reduces the impact of component wear on the safety of the cooking appliance and further enhances its safety.

[0023] In one technical solution of the present invention, the width of the gap between the limiting member and the second limiting post is greater than or equal to 1 mm and less than or equal to 10 mm.

[0024] In this technical solution, the gap between the limiting member and the second limiting post is greater than or equal to 1 mm, enabling the door position detection component to accurately detect when the door is opened, thus allowing the cooking appliance to stop working more promptly. For example, with a microswitch, a gap between the limiting member and the second limiting post of greater than or equal to 1 mm ensures that the microswitch can detect when the door is opened more accurately and promptly. A gap between the limiting member and the second limiting post of less than 10 mm allows less leakage of existing high temperatures within the cooking appliance through the gap, further reducing the risk of injury to the operator and improving the safety of the cooking appliance.

[0025] In one technical solution of the present invention, the limiting member includes a first limiting part, the limiting member is located in a third position, the first limiting part is located on the movement path of the first limiting post, the surface of the first limiting part facing the first position is a guide surface, and the guide surface has an angle with the horizontal plane.

[0026] In this technical solution, the limiting member includes a first limiting part located in a third position. When the mating member rotates from the second position to the first position, because the first limiting part is located on the movement path of the first limiting post, the limiting part can prevent the first limiting post from continuing to move, thereby preventing the mating member from continuing to rotate from the second position to the first position, thus restricting the rotation of the mating member. Since the mating member cannot rotate to the first position, the door cannot be opened under external force.

[0027] The surface of the first limiting part facing the first position is a guide surface, which forms an angle with the horizontal plane. After the door is opened, the limiting member returns to the third position. When the door needs to be closed, the operator of the cooking appliance pushes the door to close it. The door hook on the door pushes the mating part to rotate from the first position to the second position. The first limiting post on the mating part can contact the guide surface of the limiting part, thereby driving the limiting member from the third position to the fourth position through the guide surface. The first limiting post can pass over the limiting member and move to the second position, thus closing the door.

[0028] Since the surface of the first limiting part facing the first position is a guide surface, and the guide surface has an angle with the horizontal plane, the door closes more smoothly, thereby improving the feel of the cookware operator when closing the door.

[0029] In one technical solution of the present invention, the included angle is greater than 0 and less than or equal to 35 degrees.

[0030] In this technical solution, the guide surface and the horizontal plane have an angle greater than 0 and less than or equal to 35 degrees, which allows the door to drive the first limiting post past the limiting part when it receives a small pushing force, reducing the pushing force required to close the door, thereby reducing the difficulty of closing the door and further improving the user experience of the cooking appliance.

[0031] In one technical solution of the present invention, the locking component further includes a first elastic member, the first end of which is connected to the limiting member, and the second end of which is connected to the supporting member.

[0032] In this technical solution, the fixing component also includes a first elastic element. The two ends of the first elastic element are connected to the limiting element and the supporting element, respectively. When the limiting element moves to the fourth position, the first elastic element is in a stretched state. After the limiting element loses the power to maintain the fourth position, the first elastic element can drive the limiting element to return to the third position, thereby realizing the reset of the limiting element.

[0033] In one technical solution of the present invention, the limiting member is located in the third position, and the first elastic member is in a free state or a stretched state.

[0034] In this technical solution, the limiting member is located in the third position and the first elastic member is in a free state. This makes the limiting member less tensile after it moves to the fourth position, which makes it easier for the first limiting post to pass through the limiting member when closing the door, further reducing the tensile force required to close the door.

[0035] In one embodiment of the present invention, the locking component further includes a connecting post, which is disposed on the support component, and the first end of the first elastic member is hung on the connecting post.

[0036] In this technical solution, the connecting post is set on the supporting component, and the first end of the first elastic element is hung on the connecting post, thereby realizing the connection between the first elastic element and the supporting component, and thus realizing the positioning of the first end of the first elastic element, so that the first elastic element can stably drive the limiting component to reset.

[0037] In one embodiment of the present invention, the locking component further includes a second limiting part, the first end of which is connected to the connecting post, and the second end which extends in a direction away from the first elastic member.

[0038] In this technical solution, the first end of the second limiting part is connected to the connecting post, and the second end extends away from the first elastic member. When the first end of the first elastic member is sleeved on the connecting post, the first end of the first elastic member is located between the second limiting part and the supporting member. Thus, the second limiting part, in cooperation with the supporting member, confines the first elastic member to the connecting post. Even when the limiting part is in the third position, the first elastic member will not detach from the connecting post due to being in a free state or under slight tension, thus improving the stability of the first elastic member during operation.

[0039] In one embodiment of the present invention, the locking component further includes a transmission mechanism connected to the limiting member, which can push the limiting member from the third position to the fourth position.

[0040] In this technical solution, the transmission mechanism is connected to the limiting member, which can push the limiting member from the third position to the fourth position to realize the control of the limiting member, thereby making it easier for the operator of the cooking appliance to open the door.

[0041] In one technical solution of the present invention, the transmission mechanism includes a fixing member and a transmission member. The fixing member is connected to the support member. The transmission member is disposed on the fixing member and can slide relative to the fixing member. The transmission member can push the limiting member to move from the third position to the fourth position.

[0042] In this technical solution, the transmission mechanism includes a fixed member and a transmission member. Specifically, the transmission member is mounted on the fixed member and can slide relative to the fixed member. When the transmission member slides relative to the fixed member, it can push the limiting member from the third position to the fourth position, thereby unlocking the mating member.

[0043] In one technical solution of the present invention, the transmission mechanism includes a second elastic member, the first end of which is connected to a fixed member and the second end of which is connected to a transmission member, and the second elastic member can drive the transmission member to reset.

[0044] In this technical solution, the locking component also includes a second elastic element. Specifically, one end of the second elastic element is connected to the fixing element and the other end is connected to the limiting element. The second elastic element can cause the limiting element to reset after movement.

[0045] In one technical solution of the present invention, the cooking appliance further includes a control panel with an opening, a transmission component passing through the opening, and a locking component including a slide groove and a baffle; the slide groove is provided along the periphery of the opening; the baffle can be inserted into the slide groove to cover the opening.

[0046] In this technical solution, after the baffle is inserted into the slide groove, it can prevent the transmission component from extending out of the opening. This, in turn, restricts the limiting component to the fourth position via the transmission component, preventing the limiting component from restricting the movement of the first limiting post. Consequently, the door can be opened directly when needed, removing the child lock restriction and making the cooking appliance more convenient to use. Furthermore, this makes the cooking appliance suitable for both those who require child locks and those who do not, thus expanding its applicability.

[0047] According to a second aspect of the present invention, a cooking utensil is provided, including a locking component as provided by any of the above-described technical solutions, and thus possessing all the beneficial technical effects of the locking component, which will not be repeated here.

[0048] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0130] 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.

[0131] 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.

[0132] The following reference Figures 1 to 78 Describes locking components and cooking appliances according to some embodiments of the present invention.

[0133] In one embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a locking assembly is provided for a cooking appliance. The cooking appliance includes a door 810 with a door hook 820. The locking assembly includes a support member 100, a mating member 200, a first limiting post 310, and a limiting member 400. The mating member 200 is connected to the support member 100 and can rotate relative to the support member 100. The mating member 200 is provided with a mating groove 210. In a first position, the door hook 820 can disengage from the mating groove 210. In a second position, the door hook 820 engages with the mating groove 210. The first limiting post 310 is disposed on the mating member 200 and located on the side away from the rotation axis of the mating member 200; the limiting member 400 is connected to the support member 100 and has a third position and a fourth position; wherein, when the limiting member 400 is located in the third position, the limiting member 400 is located on the movement path of the first limiting post 310 and can restrict the mating member 200 from rotating from the second position to the first position; when the limiting member 400 is located in the fourth position, the limiting member 400 is away from the movement path of the first limiting post 310 and the mating member 200 can move from the second position to the first position.

[0134] In this embodiment, the locking assembly includes a support member 100 and a mating member 200. The mating member 200 is connected to the support member 100, thereby enabling the installation and fixation of the mating member 200. The mating member 200 is rotatable relative to the support member 100, and can rotate from a first position to a second position and vice versa. The mating member 200 is provided with a mating groove 210, which can engage with a door hook 820. When the mating member 200 is in the second position and the door hook 820 is located within the mating groove 210, the door 810 is in a closed state when no external force is received. When the door 810 is pulled by an external force, the door hook 820 pulls the mating member 200 from the second position to the first position, allowing the door hook 820 to disengage from the mating member 200, thereby opening the door 810. The mating part 200 is provided with a first limiting post 310. When the mating part 200 rotates, the first limiting post 310 rotates together with the mating part 200.

[0135] like Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the locking assembly also includes a limiting member 400, which is connected to the support member 100. The limiting member 400 is located in the third position and is situated on the movement path of the first limiting post 310. When the mating member 200 rotates from the second position to the first position, because the limiting member 400 is located on the movement path of the first limiting post 310, it prevents the first limiting post 310 from continuing to move. Consequently, the mating member 200 cannot continue to rotate from the second position to the first position, thus restricting the rotation of the mating member 200. Since the mating member 200 cannot rotate to the first position, the door 810 cannot be opened under external force.

[0136] like Figure 12 and Figure 13 As shown, the limiting member 400 is located in the fourth position, away from the movement path of the first limiting post 310. When the mating member 200 rotates from the second position to the first position, because the limiting member 400 is away from the movement path of the first limiting post 310, the limiting member 400 will not prevent the first limiting post 310 from continuing to move, thus allowing the mating member 200 to rotate from the second position to the first position. After the mating member 200 moves to the first position, the door hook 820 disengages from the mating member 200, realizing the opening of the door 810.

[0137] By controlling the position of the limiting member 400, the opening of the door 810 can be controlled. When the cooking appliance is in the cooking state, driving the limiting member 400 to the third position prevents the door 810 from being opened by external force. Even if a child pulls on the door 810, it will not be able to open due to the action of the limiting member 400, reducing the probability of children being burned by the high temperature inside the cooking cavity due to the door 810 being opened, reducing the safety hazards of the cooking appliance, and improving the safety of the cooking appliance.

[0138] When the door 810 needs to be opened, the drive limiter 400 moves to the fourth position, so that the door 810 can be opened under the pull of external force, which makes it easier for the operator of the cooking appliance to take out the food cooked in the cooking cavity, so that the cooking appliance can be used normally.

[0139] Since the door body 810 is restricted by limiting the movement of the mating part 200 through the limiting part 400, the locking assembly can restrict the door body 810 that cannot be rotated by the door hook 820, thereby expanding the applicability of the locking assembly.

[0140] Since the first limiting post 310 is located on the side away from the rotation axis of the mating member 200, the distance between the first limiting post 310 and the rotation axis of the mating member 200 is increased. As a result, the lever arm of the mating member 200 is lengthened during the closing of the door 810. The resistance applied to the first limiting post 310 by the limiting member 400 can be overcome with a smaller pushing force, making the closing of the door 810 easier and improving the feel of the door 810 when closing.

[0141] The first limiting post 310 is located on the side away from the rotation axis of the mating part 200, which also makes the first limiting post 310 move a longer distance during the opening and closing process, further improving the feel of the door 810 when it is closed.

[0142] The door body 810 is equipped with a handle 850, which allows users to open the door by pulling the handle 850, thus improving the user's convenience.

[0143] It is worth noting that the mating part 200 is provided with a mating groove 210, and a part of the door hook 820 is constructed as a protrusion. During the opening and closing of the door, the protrusion can slide into or out of the mating groove 210.

[0144] The locking assembly also includes a third elastic element 340 and a fourth elastic element 350. The first end of the third elastic element 340 is connected to the support member 100, and the second end of the third elastic element 340 is connected to the mating member 200. The first end of the fourth elastic element 350 is connected to the support member 100, and the second end of the fourth elastic element 350 is connected to the mating member 200. The third elastic element 340 and the fourth elastic element 350 are used to drive the mating member 200 to reset.

[0145] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0146] like Figure 2 and Figure 3 As shown, the locking assembly also includes a second limiting post 320, which is connected to the support member 100 and is located on the side of the limiting member 400 near the first position.

[0147] In this embodiment, the locking assembly further includes a second limiting post 320, which is connected to the support member 100, thus supporting and fixing the second limiting post 320. When the door 810 is pulled, the first limiting post 310, which is provided on the mating member 200, applies a pushing force from the second position to the first position to the limiting member 400. Since the second limiting post 320 is located on the side of the limiting member 400 closer to the first position, the second limiting post 320 can support the limiting member 400, thereby counteracting the pushing force applied to the limiting member 400 by the first limiting post 310, preventing the limiting member 400 from rotating under the pushing force of the first limiting post 310, so that the limiting member 400 can effectively prevent the door 810 from being opened in the third position, thereby improving the safety of the cooking appliance during the cooking process.

[0148] Specifically, the mating surface of the second limiting post 320 facing the limiting member 400 matches the mating surface of the limiting member 400 facing the second limiting post 320, thereby increasing the contact area between the second limiting post 320 and the limiting member 400, reducing the pressure between them, decreasing the probability of damage to the second limiting post 320 and the limiting member 400, and extending their service life.

[0149] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0150] like Figure 14 As shown, the limiting member 400 is in the third position, and the limiting member 400 abuts against the second limiting post 320.

[0151] In this embodiment, when the cooking appliance is in the cooking state, the limiting member 400 is in the third position and abuts against the second limiting post 320. If the door 810 is subjected to tension, the limiting member 400 can prevent the door 810 from moving, thus preventing gaps from forming between the door 810 and the housing 860 of the cooking appliance. This prevents high-temperature gas in the cooking cavity from leaking through the gap between the door 810 and the housing 860 of the cooking appliance, further improving the safety of the cooking appliance during the cooking process.

[0152] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0153] like Figure 2 and Figure 3 As shown, the limiting member 400 is located in the third position, and there is a gap between the limiting member 400 and the second limiting post 320.

[0154] In this embodiment, the limiting member 400 is located in the third position, and there is a gap between the limiting member 400 and the second limiting post 320. When the cooking appliance is in the cooking state, if the door 810 is subjected to a pulling force, the door 810 can be pulled open by a gap until the first limiting post 310 contacts the limiting member 400 and the limiting member 400 contacts the second limiting post 320, and the door 810 stops moving. While preventing the door 810 from opening, it ensures that the gap between the door 810 and the cooking appliance housing 860 can control the cooking appliance to stop working, thereby avoiding the leakage of high temperature or microwaves in the cooking cavity through the gap due to the continuous operation of the cooking appliance, which could cause injury to the operator of the cooking appliance, and further improving the safety of the cooking appliance during the cooking process.

[0155] Furthermore, by having a gap between the limiting member 400 and the second limiting post 320, even if the first limiting post 310, the limiting member 400, and the second limiting post 320 are worn due to long-term use, the high temperature or microwave inside the cooking cavity can be controlled to stop working, thereby preventing injury to the operator of the cooking appliance, reducing the impact of component wear on the safety of the cooking appliance, and further improving the safety of the cooking appliance.

[0156] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0157] like Figure 2 and Figure 3 As shown, the width of the gap between the limiting member 400 and the second limiting post 320 is greater than or equal to 1 mm and less than or equal to 10 mm.

[0158] In this embodiment, the width of the gap between the limiting member 400 and the second limiting post 320 is greater than or equal to 1 mm, enabling the position detection component of the door 810 to accurately detect that the door 810 has been opened, thereby allowing the cooking appliance to stop working more promptly. For example, with a micro switch, a gap width of greater than or equal to 1 mm ensures that the micro switch can more accurately and promptly detect that the door 810 has been opened. A gap width of less than or equal to 10 mm allows less leakage of existing high temperatures within the cooking appliance through the gap, further reducing the risk of injury to the operator and improving the safety of the cooking appliance.

[0159] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0160] like Figure 15 , Figure 16 , Figure 17 and Figure 18As shown, the limiting member 400 includes a first limiting part 410. The limiting member 400 is located in the third position. The first limiting part 410 is located on the movement path of the first limiting post 310. The surface of the first limiting part 410 facing the first position is a guide surface 420. Figure 19 and Figure 20 As shown, the guide surface 420 has an angle α with the horizontal plane.

[0161] In this embodiment, the limiting member 400 includes a first limiting part 410. The limiting member 400 is located in the third position. When the mating member 200 rotates from the second position to the first position, since the first limiting part 410 is located on the movement path of the first limiting post 310, the limiting part can prevent the first limiting post 310 from continuing to move, thereby preventing the mating member 200 from continuing to rotate from the second position to the first position, thus restricting the rotation of the mating member 200. Because the mating member 200 cannot rotate to the first position, the door 810 cannot be opened under the pull of an external force.

[0162] The surface of the first limiting part 410 facing the first position is a guide surface 420, which forms an angle with the horizontal plane. After the door 810 is opened, the limiting member 400 returns to the third position. When it is necessary to close the door 810, the operator of the cooking appliance pushes the door 810 to close it. The door hook 820 on the door 810 pushes the mating member 200 to rotate from the first position to the second position. The first limiting post 310 on the mating member 200 can contact the guide surface 420 of the limiting part, thereby driving the limiting member 400 from the third position to the fourth position through the guide surface 420. The first limiting post 310 can pass over the limiting member 400 and move to the second position, thus closing the door 810.

[0163] Since the surface of the first limiting part 410 facing the first position is the guide surface 420, and the guide surface 420 has an angle with the horizontal plane, the door 810 closes more smoothly, thereby improving the feel of the cookware operator when closing the door 810.

[0164] Furthermore, the limiting member 400 also includes a limiting member body 430 and a third limiting part 440. The limiting member body 430 is connected to the support member 100, and the third limiting part 440 cooperates with the second limiting post 320.

[0165] When the limiting member 400 is in the third position, the third limiting part 440 abuts against the second limiting post 320.

[0166] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0167] like Figure 19 and Figure 20 As shown, the included angle α is greater than 0 and less than or equal to 35 degrees.

[0168] In this embodiment, the guide surface 420 has an angle greater than 0 and less than or equal to 35 degrees with the horizontal plane, so that the door 810 can drive the first limiting post 310 to pass the limiting part when it receives a small pushing force, thereby reducing the pushing force required to close the door 810, thus reducing the difficulty of closing the door 810 and further improving the user experience of the cooking appliance operator.

[0169] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0170] like Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 , Figure 26 and Figure 27 As shown, the locking assembly also includes a first elastic member 330, the first end of which is connected to the limiting member 400, and the second end of which is connected to the supporting member 100.

[0171] In this embodiment, the fixing component further includes a first elastic member 330. The two ends of the first elastic member 330 are respectively connected to the limiting member 400 and the supporting member 100. When the limiting member 400 moves to the fourth position, the first elastic member 330 is in a stretched state. After the limiting member 400 loses the power to maintain the fourth position, the first elastic member can drive the limiting member 400 to return to the third position, thereby realizing the reset of the limiting member 400.

[0172] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0173] like Figure 3 and Figure 14 As shown, the limiting member 400 is in the third position, and the first elastic member 330 is in a free state or a stretched state.

[0174] In this embodiment, the limiting member 400 is located in the third position and the first elastic member 330 is in a free state, so that after the limiting member 400 moves to the fourth position, the limiting member 400 is subjected to less tension, thereby making it easier for the first limiting post 310 to pass through the limiting member 400 when closing the door 810, further reducing the tension required when closing the door 810.

[0175] When the limiting member 400 is in the third position, the first elastic member 330 is in a stretched state, which allows the first elastic member 330 to apply a certain tension to the limiting member 400. Under the action of the tension of the first elastic member 330, the limiting member 400 can abut against the second limiting post 320, so that the limiting member 400 can be maintained more stably in the third position and improve the accuracy of the position of the limiting member 400.

[0176] Specifically, when there is a gap between the limiting member 400 and the second limiting post 320, the first elastic member 330 is in a free state when the limiting member 400 is in the third position, that is, the first limiting member 400 is at the critical point between the tension state and the compression state. Under the action of the gravity of the limiting member 400, the first elastic member 330 only has a tension that can offset the gravity of the limiting member 400.

[0177] When there is no gap between the limiting member 400 and the second limiting post 320, the first elastic member 330 is in a stretched state when the limiting member 400 is in the third position. Under the action of the first elastic member 330, the limiting member 400 is maintained in the third position and abuts against the second limiting post 320.

[0178] Specifically, the first elastic element 330 is a spring.

[0179] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0180] like Figure 28 , Figure 29 , Figure 30 , Figure 31 and Figure 32 As shown, the locking assembly also includes a connecting post 510, which is disposed on the support member 100, and the first end of the first elastic member 330 is hung on the connecting post 510.

[0181] In this embodiment, the connecting post 510 is disposed on the support member 100, and the first end of the first elastic member 330 is hung on the connecting post 510, thereby realizing the connection between the first elastic member 330 and the support member 100, and thus realizing the positioning of the first end of the first elastic member 330, so that the first elastic member 330 can stably drive the limiting member 400 to reset.

[0182] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0183] like Figure 33 , Figure 34 , Figure 35 , Figure 36 , Figure 37 , Figure 38 , Figure 39 , Figure 40 , Figure 41 and Figure 42 As shown, the locking assembly also includes a second limiting part 520, the first end of which is connected to the connecting post 510, and the second end which extends in a direction away from the first elastic member 330.

[0184] In this embodiment, the first end of the second limiting part 520 is connected to the connecting post 510, and the second end extends away from the first elastic member 330. When the first end of the first elastic member 330 is sleeved on the connecting post 510, the first end of the first elastic member 330 is located between the second limiting part 520 and the support member 100. Thus, through the cooperation of the second limiting part 520 and the support member 100, the first elastic member 330 is limited to the connecting post 510. Even when the limiting member 400 is in the third position, the first elastic member 330 will not detach from the connecting post 510 due to being in a free state or a small stretching state, thus improving the stability of the first elastic member 330 during operation.

[0185] Specifically, the axis of the connecting column 510 is perpendicular to the support member 100, the first end of the connecting column 510 is connected to the support member 100, and the second end of the connecting column 510 is connected to the second limiting part 520.

[0186] The axis of the connecting column 510 is perpendicular to the second limiting part 520, which extends along the surface of the support member 100.

[0187] Furthermore, the support component 100, the connecting column 510, and the second limiting part 520 are an integral structure.

[0188] Optionally, the connecting part can also be inclined relative to the support member 100. The first end of the connecting part is connected to the support member 100, and the second end extends inclined away from the first elastic member. Thus, under the action of the connecting part, the first elastic member 330 can be prevented from detaching from the connecting post 510 when it is in a free state or a small stretching state, thereby eliminating the need for the second limiting part 520 and simplifying the structure of the locking assembly.

[0189] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0190] like Figure 43 , Figure 44 , Figure 45 , Figure 46 , Figure 47 , Figure 48 , Figure 49 and Figure 50As shown, the locking assembly also includes a transmission mechanism 600, which is connected to the limiting member 400 and can push the limiting member 400 from the third position to the fourth position.

[0191] In this embodiment, the transmission mechanism 600 is connected to the limiting member 400, which can push the limiting member 400 from the third position to the fourth position, thereby controlling the limiting member 400 and making it easier for the operator of the cooking appliance to open the door 810.

[0192] Specifically, when the cooking appliance is in the cooking state, the limiting member 400 is maintained in the third position under the action of the first elastic member 330. After the operator of the cooking appliance puts the ingredients into the cooking cavity of the cooking appliance, they begin to cook the ingredients. At this time, the limiting member 400 is in the third position, located on the movement path of the first limiting post 310. Even if the operator of the cooking appliance or a child pulls the door 810, the limiting member 400 will block the movement of the first limiting post 310, and the cooperating member 200 cannot move to the first position, thus preventing the door 810 from being opened.

[0193] After cooking is completed, or when it is necessary to open the door 810, the operator of the cooking appliance drives the limiting member 400 to the fourth position via the transmission mechanism 600, and the limiting member 400 disengages from the movement path of the first limiting post 310. At this time, the operator of the cooking appliance pulls the door 810, thereby opening the door 810.

[0194] Understandably, a portion of the transmission mechanism 600 can be exposed outside the door body 810, thereby facilitating the user to unlock the mating part 200 by operating the portion of the transmission mechanism 600 exposed outside the door body 810, thus enabling the door body 810 to be opened.

[0195] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0196] like Figure 51 , Figure 52 , Figure 53 , Figure 54 , Figure 55 , Figure 56 , Figure 57 , Figure 58 , Figure 59 , Figure 60 , Figure 61 and Figure 62 As shown, the transmission mechanism 600 includes a fixing member 610 and a transmission member 620. The fixing member 610 is connected to the support member 100. The transmission member 620 is disposed on the fixing member 610 and can slide relative to the fixing member 610. The transmission member 620 can push the limiting member 400 from the third position to the fourth position.

[0197] In this embodiment, the transmission mechanism 600 includes a fixing member 610 and a transmission member 620. Specifically, the transmission member 620 is disposed on the fixing member 610 and can slide relative to the fixing member 610. When the transmission member 620 slides relative to the fixing member 610, the transmission member 620 can push the limiting member 400 from the third position to the fourth position, so that the mating member 200 is unlocked.

[0198] In detail, when the limiting member 400 is in the third position, the limiting member 400 can restrict the movement of the mating member 200. Since the limiting member 400 restricts the movement of the mating member 200, and the mating groove 210 of the mating member 200 engages with the door hook 820, the door hook 820 cannot move to the open position. Even if the door hook 820 is locked in the closed position, that is, when the limiting member 400 is in the third position, even if the handle 850 of the door body 810 is pulled, the door body 810 cannot be opened.

[0199] When the door 810 needs to be opened, the transmission component 620 slides relative to the fixed component 610, thereby causing the transmission component 620 to push the limiting component 400 from the third position to the fourth position. When the limiting component 400 is in the fourth position, the limiting component 400 can release the movement restriction on the mating component 200. That is, the mating component 200 is unlocked. At this time, pulling the handle 850 of the door 810 will cause the door hook 820 to drive the mating component 200 to move until the door hook 820 slides out of the mating groove 210, thus moving the door hook 820 to the open position and realizing the opening operation of the door 810.

[0200] By setting the limiting member 400 to move between the third and fourth positions, when you want to open the door 810, you need to first slide the transmission member 620 relative to the fixed member 610, and push the limiting member 400 to the fourth position during the sliding process, thereby releasing the movement restriction on the mating member 200, so that the door can be opened. This increases the steps to open the door 810, thereby increasing the difficulty of opening the door 810. This reduces the risk of children being burned by the heated food or utensils in the cooking cavity due to accidentally touching the door opening button or handle and opening the oven door with a light press or pull. It effectively avoids accidental operation and thus effectively improves the safety of using cooking utensils with this locking component.

[0201] Furthermore, the fixing member 610 is provided with a sliding channel, a part of the transmission member 620 passes through the sliding channel, and the transmission member 620 can slide in the sliding channel, so that when the transmission member 620 moves, it can slide relative to the fixing member 610 in the sliding channel, and then push the limiting member 400 to move during the sliding process, so that the mating member 200 is unlocked.

[0202] It is understandable that the sliding channel is a closed channel on all four sides, which allows the sliding trajectory of the transmission component 620 to be limited during the sliding process of the transmission component 620, ensuring the stability of the movement of the transmission component 620 within the sliding channel, enabling the transmission component 620 to effectively push the limiting component 400 during the sliding process, thereby enabling the mating component 200 to be effectively unlocked, and ensuring the stable operation of the door 810 opening and closing.

[0203] Furthermore, the transmission member 620 includes a trigger part and a first transmission part. Specifically, the first transmission part is disposed on the trigger part. When the trigger part is triggered, the trigger part can drive the first transmission part to slide relative to the fixed member 610. During the sliding process, the first transmission part pushes the limiting member 400 to move to the second position to release the movement restriction on the mating member 200.

[0204] Furthermore, the transmission member 620 also includes a stop portion. Specifically, the stop portion is disposed on one end of the trigger portion. When the transmission member 620 moves away from the limit member 400, the stop portion can abut against the fixing member 610 to prevent the trigger portion from moving excessively and to ensure the effective operation of the locking assembly's door opening and closing process.

[0205] Furthermore, the locking assembly also includes a second support portion. Specifically, the fixing member 610 is provided with a first support portion, and the second support portion is provided on the transmission member 620. Specifically, the second support portion is provided on the trigger portion, and the second support portion is located on the first support portion and can slide relative to the first support portion.

[0206] In other words, the second support is located above the first support, and during the process of the trigger being triggered and driving the first transmission part to slide relative to the fixed member 610, or the second elastic member 630 driving the transmission member 620 to reset, the second support can slide on the first support. Thus, while effectively realizing the door opening and closing process, the stability and reliability of the transmission member 620 when sliding relative to the fixed member 610 are further improved through the cooperation and support between the first support and the second support, preventing the transmission member 620 from shaking when sliding relative to the fixed member 610, and ensuring that the first transmission part can push the limiting member 400 to the second position during the sliding process to unlock the cooperating member 200, thereby completing the door opening operation.

[0207] In addition, the fastener 610 is used for the fixed connection of the transmission mechanism 600, and the second support part connected to the transmission member 620 is located on the first support part, so that the first support part can support the second support part, thereby improving the installation stability of the transmission member 620.

[0208] The second support section and the trigger section are an integral structure.

[0209] Furthermore, the fixing member 610 includes a fixing member body 612, a wall guide rail 614, a sliding surface 616, an insert 618, and a connecting hole 619. The wall guide rail 614 is used to assist the sliding of the transmission component. The insert 618 is used to insert into the insertion hole on the support component 100, thereby realizing the installation and fixing of the fixing member 610. When the door 810 is opened, the sliding surface 616 assists in restricting the movement of the limiting member 400 vertically supporting the support component 100. The connecting hole 619 cooperates with the pivot of the rotating lever on the support component 100.

[0210] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0211] like Figure 43 , Figure 44 , Figure 45 , Figure 46 , Figure 47 , Figure 48 , Figure 49 and Figure 50 As shown, the transmission mechanism 600 includes a second elastic member 630. The first end of the second elastic member 630 is connected to the fixed member 610, and the second end is connected to the transmission member 620. The second elastic member 630 can drive the transmission member 620 to reset.

[0212] In this embodiment, the locking component further includes a second elastic member 630. Specifically, one end of the second elastic member 630 is connected to the fixing member 610, and the other end is connected to the limiting member 400. The second elastic member 630 can cause the limiting member 400 to reset after movement.

[0213] In detail, such as Figure 63 , Figure 64 , Figure 65 , Figure 66 , Figure 67 and Figure 68 As shown, the mating part 200 is provided with a mating groove 210. When the limiting part 400 is in the third position, the limiting part 400 can restrict the movement of the mating part 200. Since the limiting part 400 restricts the movement of the mating part 200, and the mating groove 210 of the mating part 200 is engaged with the door hook 820, the door hook 820 cannot move to the open position. Even if the door hook 820 is locked in the closed position, that is, when the limiting part 400 is in the third position, even if the handle 850 of the door body 810 is pulled, the door body 810 cannot be opened.

[0214] When the door 810 needs to be opened, the transmission member 620 slides relative to the fixed member 610, thereby pushing the limiting member 400 from the third position to the fourth position. When the limiting member 400 is in the fourth position, it releases the restriction on the movement of the mating member 200. At this time, the second elastic member 630 undergoes elastic deformation, for example, it is stretched, meaning the mating member 200 is unlocked. Then, pulling the handle 850 of the door 810 causes the door hook 820 to move the mating member 200 until it slides out of the mating groove 210, thus moving the door hook 820 to the open position and opening the door 810. After the door 810 is opened, the second elastic member 630 drives the limiting member 400 to move in the direction of the third position, that is, the second elastic member 630 drives the limiting member 400 to move in the opposite direction to reset.

[0215] By setting the second elastic element 630, the limit element 400 can be automatically reset after movement, ensuring the effective operation of the door 810 opening and closing, improving the convenience of users using cooking appliances with this locking component, and thus enhancing the user experience.

[0216] The second elastic element 630 is a tension spring.

[0217] Furthermore, the fastener 610 includes a first hook 617, and a second elastic member 630 is attached to the first hook 617.

[0218] The transmission component 620 includes a drive column 628, a first positioning surface 622, a second positioning surface 624, and a second hook 626. A second elastic element 630 is hung on the second hook 626. The first positioning surface 622 and the second positioning surface 624 cooperate with the fixing element 610 to position the transmission component 620. The drive column 628 can drive the limiting element 400 to move.

[0219] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0220] like Figure 69 , Figure 70 , Figure 71 , Figure 72 , Figure 73 and Figure 74 As shown, the cooking appliance also includes a control panel 830, which has an opening 840. The transmission component 620 passes through the opening 840. The locking assembly also includes a slide 710 and a baffle 720. The slide 710 is arranged around the periphery of the opening 840. The baffle 720 can be inserted into the slide 710 to cover the opening 840.

[0221] In this embodiment, after the baffle 720 is inserted into the slide groove 710, the baffle 720 can prevent the transmission member 620 from extending out of the opening 840. This, in turn, restricts the limiting member 400 to the fourth position via the transmission member 620, preventing the limiting member 400 from restricting the movement of the first limiting post 310. Consequently, the door 810 can be opened directly when needed, removing the child lock restriction and making the cooking appliance more convenient to use. Furthermore, this makes the cooking appliance suitable for both those who require child locks and those who do not, thus expanding its applicability.

[0222] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0223] like Figure 26 As shown, the support component 100 includes a first bracket 110 and a second bracket 120. Specifically, the first bracket 110 is connected to the second bracket 120, and the first bracket 110 and the second bracket 120 together form a receiving cavity, that is, the side of the first bracket 110 near the second bracket 120 and the side of the second bracket 120 near the first bracket 110 form the receiving cavity. The mating component 200 is located within the receiving cavity, that is, the receiving cavity provides installation space for the mating component 200. This protects the mating component 200, prevents external forces from acting directly on the mating component 200, and thus extends the service life of the mating component 200.

[0224] Furthermore, by placing a portion of the mating part 200 within the receiving cavity, dirt and impurities can be reduced from entering the mating part 200, ensuring the cleanliness of the mating part 200 and thus ensuring the reliability of the mating of each component of the locking assembly.

[0225] The mating part 200 is disposed on the first bracket 110 and can rotate relative to the first bracket 110. That is, during the opening and closing of the door, the door hook 820 engages with the mating groove 210 of the mating part 200, thereby causing the mating part 200 to rotate relative to the first bracket 110 to complete the opening and closing operation.

[0226] The limiting member 400 is disposed on the side of the second bracket 120 away from the receiving cavity, and the limiting member 400 can rotate relative to the second bracket 120. When the transmission member 620 slides relative to the fixed member 610, the transmission member 620 can push the limiting member 400 to rotate from the first position to the second position, thereby releasing the movement restriction on the mating member 200. By pulling the door body 810, the door can be opened through the cooperation of the door hook 820 and the mating member 200.

[0227] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0228] The locking assembly also includes a first clearance opening 130, which is disposed on the second bracket 120. The first limiting post 310 extends out of the second bracket 120 through the first clearance opening 130 and can move within the first clearance opening 130. Specifically, based on the limiting member 400 being in the first position, the first limiting post 310 is located on the first side of the first clearance opening 130, and the limiting member 400 prevents the first limiting post 310 from moving from the first side to the second side of the first clearance opening 130. Based on the limiting member 400 being in the second position, the first limiting post 310 can move from the first side to the second side.

[0229] In this embodiment, the locking component further includes a first clearance opening 130. Specifically, the first clearance opening 130 is disposed on the second bracket 120, and the mating component 200 is provided with a first limiting post 310. The first limiting post 310 extends out of the second bracket 120 through the first clearance opening 130, that is, the first clearance opening 130 is in communication with the receiving cavity.

[0230] During the opening and closing of the door, the first limiting post 310 can move within the first clearance opening 130. The second bracket 120 includes a first side and a second side located in the first clearance opening 130 and disposed opposite to each other. It is understood that when the first limiting post 310 is located on the first side, the door 810 is closed, and when the first limiting post 310 moves from the first side to the second side, the door 810 is opened.

[0231] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0232] The locking assembly also includes a second support surface, which is located on the side of the second bracket 120 near the limiting member 400. The limiting member 400 is provided with a first support surface, which is in contact with the second support surface and can move relative to the second support surface.

[0233] In this embodiment, the locking component further includes a second support surface. Specifically, the second support surface is disposed on the side of the second bracket 120 near the limiting member 400. The limiting member 400 is provided with a first support surface. The first support surface is in contact with the second support surface, and the first support surface can move relative to the second support surface, that is, the first support surface can move on the second support surface.

[0234] By setting a second support surface, the limiting member 400 can be supported, preventing the limiting member 400 from moving towards the second support 120 during rotation relative to the second support 120. This prevents the limiting member 400 from shaking, improves the stability and reliability of the limiting member 400 during movement, and ensures the effective operation of the door opening and closing process, thereby enhancing the user's experience of using cooking appliances with this locking component.

[0235] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0236] The locking assembly also includes a limiting wall, which is disposed on the second bracket 120 and located on the first side of the first clearance opening 130. When the limiting member 400 moves to the second position, it contacts the limiting wall.

[0237] In this embodiment, the locking component further includes a limiting wall. Specifically, the limiting wall is disposed on the second bracket 120 and located on the first side of the first clearance opening 130. When the limiting member 400 moves to the second position, the limiting member 400 contacts the limiting wall, thereby limiting the limiting member 400 and preventing the limiting member 400 from continuing to rotate. Even if the limiting member 400 can only rotate within a certain range, the problem of excessive rotation of the limiting member 400 and interference with other components is further avoided, thereby improving the reliability of the cooking appliance with this locking component in the opening and closing process.

[0238] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0239] like Figure 75 , Figure 76 , Figure 77 and Figure 78 As shown, the locking assembly also includes a buffer 530, which is connected to the mating member 200 and is used to reduce the rotational speed of the mating member 200 when it rotates away from the door hook 820.

[0240] In this embodiment, the locking assembly further includes a buffer 530. Specifically, the buffer 530 is connected to the mating member 200, and the buffer 530 can slow down the rotational speed of the mating member 200 when it rotates away from the door hook 820. It is understood that when the door 810 is opened, the door hook 820 pulls the mating member 200 towards the door hook 820; when the door 810 is closed, the door hook 820 pushes the mating member 200 away from the door hook 820. In other words, the buffer 530 can slow down the rotational speed of the mating member 200 when the door is closed, thereby slowing down the closing speed of the door 810, reducing noise generated during closing, and improving the user experience.

[0241] In practical applications, the buffer 530 includes a damper.

[0242] The buffer 530 is disposed on the first bracket 110 and is located in the accommodating cavity, thereby providing accommodating space for the buffer 530, protecting the buffer 530, preventing external forces from acting directly on the buffer 530, and thus extending the service life of the buffer 530.

[0243] In addition, by placing the buffer 530 inside the accommodating cavity, dirt and impurities can be reduced from entering the buffer 530, ensuring the cleanliness of the buffer 530 and thus ensuring the reliability of the cooperation of each component of the locking assembly.

[0244] This embodiment provides a locking component, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0245] The mating part 200 is provided with an adapter groove and an adapter part 540. The adapter part 540 is located in the adapter groove, and the buffer part 530 is connected to the mating part 200 through the adapter part 540.

[0246] In this embodiment, the mating member 200 is provided with a transition groove and a transition part 540. Specifically, the transition part 540 is disposed in the transition groove, and the buffer member 530 is connected to the mating member 200 through the transition part 540. That is to say, the transition groove has the function of accommodating the transition part 540 and connecting the transition part 540 to ensure the mating dimensions of the transition part 540 and the buffer member 530.

[0247] Specifically, the adapter 540 is detachably connected to the adapter slot. This design reduces the processing difficulty of the product, facilitates mass production of the adapter 540, and helps reduce the production cost of the product. Because the adapter 540 is detachably connected to the adapter slot, when the adapter 540 is severely worn, the normal use of the product can be ensured by replacing the adapter 540, which helps reduce the cost of subsequent repair and maintenance.

[0248] In one embodiment of the present invention, a cooking appliance is provided, including a locking component as provided in any of the above embodiments, and thus possesses all the beneficial technical effects of the locking component, which will not be repeated here.

[0249] Furthermore, the cooking appliance also includes an appliance body and a door 810. The appliance body has a cooking cavity, and a locking component is located on the appliance body and at the opening 840 end of the cooking cavity. The door 810 is connected to the appliance body in an openable and closable manner, and the door 810 includes a door hook 820.

[0250] The cooking appliance provided in this embodiment of the invention includes an appliance body, a locking component, and a door 810. Specifically, the appliance body is provided with a cooking cavity, the door 810 is disposed on the appliance body and the door 810 can open or close the cooking cavity, the locking component is disposed on the appliance body and the locking component is located at the opening 840 end of the cooking cavity. It can be understood that after the user opens the door 810, the food inside the cooking cavity can be taken out or put in through the opening 840 end of the cooking cavity.

[0251] The door body 810 includes a door hook 820, which is fixed relative to the door body 810. That is, the door hook 820 is a fixed door hook 820, and the opening and closing operation of the door body 810 is achieved through the cooperation of the fixed door hook 820 and the mating part 200. It is worth noting that the door body 810 is provided with an upper door hook 820 and a lower door hook 820. Both the upper and lower door hooks 820 can be fixed, or the lower door hook 820 can be fixed while the upper door hook 820 is movable; the specific configuration can be determined according to actual needs.

[0252] The locking component provided by this invention can be installed on cooking appliances to form a composite system, which is easy to install, requires little modification to the overall cooking appliance, and also has the option to disable the child lock function.
