Description

Technical Field

[0001] The present application relates to the technical field of cooking appliances, and in particular to a cooking appliance and a cabinet assembly. Background Art

[0002] In the related art, cooking appliances embedded in cabinet assemblies consist of a pull-down door and a main unit, rotatably connected to the main unit via a hinge. When the pull-down door is opened or closed, it rotates around the hinge, with a fixed rotation radius. This requires a large gap between the bottom of the pull-down door and the cabinet assembly to prevent interference when opening or closing the door. This large gap between the cooking appliance and the cabinet assembly detracts from the overall aesthetics and easily accumulates dust. Utility Model Content

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

[0004] To this end, a first aspect of the present application provides a cooking appliance.

[0005] A second aspect of the present application provides a cabinet assembly.

[0006] In view of this, the first aspect of the present application provides a cooking appliance, comprising: an appliance body, the appliance body being provided with a cooking cavity; a door body; a hinge structure, the door body and the appliance body being connected by the hinge structure to be opened and closed, the hinge structure comprising: a hinge shell group, which is provided on the door body, the hinge shell group being provided with a first slide groove; a connecting rod assembly, which connects the hinge shell group and the appliance body, the connecting rod assembly being provided with a second slide groove, the connecting rod assembly being used to deform when the door body is opened to drive the door body to move along a first direction toward the appliance body; an elastic member, which is provided on the hinge shell group; a pull rod assembly, the pull rod assembly being slidably connected to either the first slide groove and the second slide groove, and the pull rod assembly is connected to the elastic member; the first slide groove and the second slide groove cooperate to adjust the deformation amount of the elastic member through the pull rod assembly when the door body is in the first open state; the elastic member is used to stop the door body from rotating when the door body is in the second open state, and to drive the door body to reset in the process of the door body closing the cooking cavity; wherein, the door opening angle corresponding to the first open state is smaller than the door opening angle corresponding to the second open state.

[0007] The present application provides a cooking appliance comprising an appliance body, a door, and a hinge structure. The appliance body is provided with a cooking cavity, and the door and the appliance body are connected to each other in an openable and closable manner via the hinge structure, and the door is used to open or close the cooking cavity.

[0008] The hinge structure includes a hinge shell assembly, a connecting rod assembly, an elastic member and a pull rod assembly.

[0009] The hinge shell assembly is arranged on the door body, and the door body serves as a mounting carrier of the hinge shell assembly and has the function of mounting and fixing the hinge shell assembly.

[0010] The connecting rod assembly is connected to the hinge shell group, and the connecting rod assembly is connected to the appliance body. The connecting rod assembly is connected between the hinge shell group and the appliance body. When an external force acts on the door body and the door body is opened, the connecting rod assembly deforms as the door body moves, so that the door body is opened and the door body is driven to move along a first direction toward the appliance body. When the door body is a pull-down door body, the door body is opened, and the connecting rod assembly deforms to drive the door body to move in an obliquely upward direction (i.e., an upward and inward direction) toward the appliance body. When the door body is a pull-up door body, the connecting rod assembly deforms to drive the door body to move in an obliquely downward direction (i.e., a downward and inward direction) toward the appliance body when the door body is opened. That is to say, during the process of opening and closing the door, the connecting rod assembly changes the opening and closing trajectories of the door body through its own deformation.

[0011] This prevents the door from interfering with the mounting support for the cooking appliance (e.g., the cabinet body of the cabinet assembly) during opening and closing. Specifically, when the cooking appliance is embedded, the door moves in a first direction toward the appliance body under the action of the connecting rod assembly during opening and closing. Therefore, the door does not interfere with the mounting support. This adaptively reduces the installation gap between the cooking appliance and the mounting support, ensuring an aesthetically pleasing overall appearance. Furthermore, by reducing the installation gap between the cooking appliance and the mounting support, dust and other impurities that accumulate in the gap between the cooking appliance and the mounting support are reduced, thereby improving product performance.

[0012] Furthermore, the hinge housing assembly is provided with a first sliding groove, the connecting rod assembly is provided with a second sliding groove, the pull rod assembly is slidably connected to the first sliding groove, the pull rod assembly is slidably connected to the second sliding groove, and the elastic member is connected between the hinge housing assembly and the pull rod assembly.

[0013] It can be understood that the connecting rod assembly is slidingly connected to either the first slide groove or the second slide groove, and the first slide groove and the second slide groove cooperate with each other (such as the setting position of the first slide groove and the second slide groove, such as the shape of the first slide groove and the second slide groove) to have the function of limiting the movement trajectory of the pull rod assembly.

[0014] When the door is opened and in a first open state (e.g., a small-angle open state), the pull rod assembly slides along the first slot and cooperates with the pull rod assembly to slide along the second slot. The first slot and the second slot cooperate to limit the offset position of the pull rod assembly, thereby indirectly adjusting the deformation of the elastic member. In other words, the length of the elastic member from the connection between the hinged housing assembly and the elastic member to the connection between the pull rod assembly and the elastic member is adjusted to meet the requirements of the sliding door and automatic door closing load when the door is in the first open state. When the external force acting on the door is removed, the door can automatically close under the action of the elastic member.

[0015] When the door body is opened and is in the second opening state (e.g., a large-angle opening state), the elastic member is in a stretched state, and the tension of the elastic member is equal to the torque generated by the weight of the door body, so that the door body is suspended at any angle when opening. That is, the tension of the elastic member matches the torque generated by the weight of the door body, so that when the door body is in the second opening state, the elastic member has the effect of stopping the door body from continuing to rotate, limiting the rotation of the door body, and the door body is suspended at a predetermined position. At this time, the door body will not be closed, and the user can place or take food materials in or out of the cooking cavity of the appliance body, which is convenient for the user to operate.

[0016] When the door body is closed, that is, during the process of closing the cooking cavity, the elastic member switches from the stretched state to the retracted state, and the sum of the external force acting on the door body and the elastic tension provided by the retraction of the elastic member is greater than the torque generated by the weight of the door body, so that the door body can be automatically closed under the action of the elastic member.

[0017] It can be understood that the connecting rod assembly is in sliding connection with any one of the first sliding groove and the second sliding groove, so that when the door body is closed, the first sliding groove, the second sliding groove and the connecting rod assembly cooperate to define the movement track of the door body, so that the door body can be effectively reset to the appliance body to effectively close the cooking cavity.

[0018] According to the cooking appliance described above, the following additional technical features can also be provided:

[0019] In some embodiments, optionally, the first sliding groove comprises: a straight groove segment; and an arc-shaped segment connected with the straight groove segment; when the door body is in the closed state, the straight groove segment extends along the second direction, and the arc-shaped segment extends from the straight groove segment towards the appliance body in a direction away from one side of the elastic member; when the door body is in the first opening state, the connecting position of the connecting rod assembly and the first sliding groove is located at the arc-shaped segment; and when the door body is in the second opening state, the connecting position of the connecting rod assembly and the first sliding groove is located at the straight groove segment.

[0020] In this embodiment, the first sliding groove comprises the straight groove segment and the arc-shaped segment, and the arc-shaped segment is connected with the straight groove segment. The connecting rod assembly can slide at the straight groove segment and the arc-shaped segment.

[0021] When the door body is in the closed state, the straight groove segment extends along the second direction, and the arc-shaped segment extends from the straight groove segment towards the appliance body in a direction away from one side of the elastic member. That is, the extension direction of the first sliding groove when the door body is in the closed state is defined.

[0022] Specifically, when the door body is in the first opening state, the connecting position of the pull rod assembly and the first sliding groove is located at the arc segment. That is, when the door body is in the small-angle opening state, the pull rod assembly slides along the arc segment, and cooperates with the pull rod assembly to slide along the second sliding groove. The arc segment and the second sliding groove are matched to limit the offset position of the pull rod assembly, thereby indirectly adjusting the deformation amount of the elastic member to meet the needs of the door load and the automatic door closing load when the door body is in the first opening state. It can be understood that the setting positions of the arc segment and the second sliding groove and the shapes thereof are matched to adjust the offset position of the pull rod assembly when the door body is opened.

[0023] Specifically, when the door body is in the second opening state, the connecting position of the pull rod assembly and the first sliding groove is located at the straight slot segment. That is, when the door body is in the large-angle opening state, the pull rod assembly slides along the straight slot segment to provide structural support for increasing the deformation amount of the elastic member. When the door body is in the second opening state, the elastic force of the elastic member can match the torque generated by the weight of the door body, thereby providing structural support for the door body hovering at the predetermined position.

[0024] In some embodiments, optionally, the second sliding groove is oppositely arranged with the first sliding groove; when the door body is in the closed state, the second sliding groove is obliquely extended from the appliance body to the door body, and the distance from the groove wall of the second sliding groove towards the bottom of the door body to the bottom of the door body gradually decreases.

[0025] In this embodiment, the setting position of the second sliding groove and the shape of the second sliding groove are further limited.

[0026] The second sliding groove is oppositely arranged with the first sliding groove.

[0027] When the door body is in the closed state, the second sliding groove is obliquely extended. Specifically, from the appliance body to the door body, the distance from the groove wall of the second sliding groove towards the bottom of the door body to the bottom of the door body gradually decreases.

[0028] When the door body is in the first opening state, the pull rod assembly slides along the arc segment, and at the same time, the pull rod assembly slides obliquely downward along the second sliding groove. The arc segment and the second sliding groove are matched to limit the offset position of the pull rod assembly, thereby indirectly adjusting the deformation amount of the elastic member to meet the needs of the door load and the automatic door closing load when the door body is in the first opening state. It can be understood that the setting positions of the arc segment and the second sliding groove and the shapes thereof are matched to adjust the offset position of the pull rod assembly when the door body is opened.

[0029] Specifically, when the door body is in the second open state, the pull rod assembly slides along the straight groove section, and the connection between the pull rod assembly and the second slide groove is located at the end of the second slide groove away from the appliance body. This setting provides structural support for increasing the deformation of the elastic member, so that when the door body is in the second open state, the tension of the elastic member can match the torque generated by the weight of the door body, thereby providing structural support for the door body to hover in a predetermined position.

[0030] In some embodiments, optionally, the hinge shell group includes: a hinge shell, the hinge shell is provided with a mounting cavity having an opening, the opening is arranged opposite to the device body, a part of the connecting rod assembly is located in the mounting cavity and is rotatably connected to the hinge shell, and the elastic member and the pull rod assembly are both provided in the mounting cavity; a fixed block, provided in the mounting cavity, and the fixed block is provided with a first sliding groove.

[0031] In this embodiment, the structure of the hinge housing assembly is further defined.

[0032] Specifically, the hinge housing assembly includes a hinge housing and a fixing block.

[0033] The hinge shell is provided with a mounting cavity with an opening, and the opening of the hinge shell is arranged opposite to the device body. It can be understood that the hinge shell is a groove structure with an opening, and the hinge shell extends along the second direction.

[0034] A portion of the connecting rod assembly is located within the mounting cavity and is rotatably connected to the hinge housing. The elastic member, tie rod assembly, and fixed block are all located within the mounting cavity. In other words, the hinge housing serves to mount and secure the elastic member, tie rod assembly, and fixed block, ensuring their proper dimensions and preventing them from being exposed. This ensures the cookware maintains its aesthetically pleasing appearance when the door is opened or closed.

[0035] Furthermore, the fixing block is provided with a first sliding groove, and the fixing block is slidably connected to the pull rod assembly.

[0036] In some embodiments, optionally, the fixed block includes: a support plate; two vertical plates, the two vertical plates are arranged at intervals on the side of the support plate facing the device body, each vertical plate is provided with a first slide groove, and the pull rod assembly is located between the two vertical plates; the hinged structure also includes two first rollers and a second roller, the pull rod assembly is slidably connected to the two first slide grooves of the fixed block through the two first rollers, and the pull rod assembly is slidably connected to the second slide groove through the second roller.

[0037] In this embodiment, the structure of the fixing block is further defined.

[0038] The fixing block includes a support plate and two vertical plates, the support plate is located in the installation cavity and is connected to the hinge shell. The two vertical plates are both connected to the side of the support plate facing the device body and are arranged at intervals.

[0039] Any one of the two vertical plates is provided with a first sliding groove, and the first sliding grooves of the two vertical plates are arranged opposite to each other.

[0040] The pull rod assembly is located between the two vertical plates. It can be understood that the pull rod assembly is accommodated in the space enclosed by the two vertical plates and the support plate.

[0041] The hinged structure also includes two first rollers, through which the rod assembly slides in contact with the two first slots of the fixed block. That is, each first roller slides in contact with a first slot on a vertical plate, and the rod assembly slides along the first slots of the fixed block via the two first rollers. This arrangement increases the contact area and angle between the rod assembly and the fixed block, ensuring balanced and consistent force distribution across the rod assembly, allowing the rod assembly to slide stably along the first slots.

[0042] The cooking utensil further comprises a second roller, and the pull rod assembly is slidably connected to the second sliding groove of the connecting rod assembly via the second roller. That is, the pull rod assembly slides along the second sliding groove of the connecting rod assembly via the second roller.

[0043] The first roller is in sliding engagement with the first slide groove, and the second roller is in sliding engagement with the second slide groove. This arrangement can ensure the smoothness of the pull rod assembly during movement and can avoid jamming.

[0044] In some embodiments, optionally, the pull rod assembly includes: a first pull rod, the first pull rod connecting the two first rollers and the second roller; a second pull rod, the second pull rod is rotatably connected to the first pull rod, and the second pull rod is connected to the elastic member.

[0045] In this embodiment, the structure of the tie rod assembly is further defined.

[0046] Specifically, the pull rod assembly includes a first pull rod and a second pull rod.

[0047] The first pull rod connects the two first rollers and the second roller, that is, the first pull rod serves as a mounting carrier for the two first rollers and the second roller, and has the function of mounting and fixing the two first rollers and the second roller.

[0048] The second pull rod is rotatably connected to the first pull rod, and the second pull rod is connected to the elastic member, that is, the first pull rod and the elastic member are connected through the second pull rod.

[0049] In some embodiments, optionally, the connecting rod assembly, the device body and the hinge shell assembly form a quadrilateral structure.

[0050] In this embodiment, the matching structures of the connecting rod assembly, the tool body and the hinge housing assembly are further defined.

[0051] Specifically, the connecting rod assembly, the appliance body and the hinge shell assembly form a quadrilateral structure. When an external force acts on the door body and the door body is opened, the quadrilateral structure deforms to achieve the purpose of driving the door body to move along the first direction toward the appliance body.

[0052] It can be understood that the connecting rod assembly, the appliance body and the hinged shell assembly constitute a quadrilateral structure, which has a tensile limit and a shortening limit. The deformation of the connecting rod assembly can indirectly limit the switching limit position of the door body and the appliance body, ensure the effective matching size of the door body and the appliance body, and ensure the reliability and stability of the door body in opening and closing the cooking cavity.

[0053] In some embodiments, optionally, the connecting rod assembly includes: a hinge arm, the hinge arm is provided on the appliance body; a first connecting rod, the first connecting rod is provided with a slot and a second slide groove, a portion of the hinge arm is inserted into the slot and is rotatably connected to the first connecting rod, and the first connecting rod is rotatably connected to the hinge shell group; two second connecting rods, the hinge arm is rotatably connected between the two second connecting rods, and each second connecting rod is rotatably connected to the hinge shell group; wherein, when the door body is in a closed state, along the second direction, the position of the first connecting rod is higher than the position of the second connecting rod.

[0054] In this embodiment, the structure of the connecting rod assembly is further defined.

[0055] Specifically, the link assembly includes a hinge arm, a first link, and two second links.

[0056] The hinge arm is arranged on the device body, that is, the device body serves as a mounting carrier of the hinge arm and has the function of mounting and fixing the junction arm.

[0057] The first connecting rod is provided with a slot and a second sliding groove, a part of the hinge arm is inserted into the slot and is rotatably connected to the first connecting rod, and the first connecting rod is rotatably connected to the hinge housing assembly. The second sliding groove is located on one side of the slot.

[0058] Any one of the two second connecting rods is rotatably connected to the hinge arm, and the hinge arm is located between the two second connecting rods. Any one of the two second connecting rods is rotatably connected to the hinge housing assembly.

[0059] It can be seen from this that the hinge arm, the first connecting rod, the two second connecting rods, the device body and the hinge shell group form a quadrilateral structure.

[0060] The first connecting rod has a first end and a second end, and the second connecting rod has a third end and a fourth end, wherein the first end is rotatably connected to the hinge arm, the second end is rotatably connected to the hinge housing assembly, the third end is rotatably connected to the hinge arm, and the fourth end is rotatably connected to the hinge housing assembly.

[0061] The following takes a pull-down door as an example.

[0062] Specifically, when the door body is in a closed state, along the second direction, the position of the first connecting rod is higher than the position of the second connecting rod.

[0063] Specifically, when the door switches from a closed state to an open state, the second connecting rod is tilted. The distance from the third end of the second connecting rod to the bottom of the cooking appliance is less than the distance from the fourth end of the second connecting rod to the bottom of the cooking appliance. In other words, the second connecting rod is tilted upward, so that the movement of the second connecting rod causes the fourth end to gradually move closer to the appliance body, thereby driving the door closer to the appliance body, ultimately achieving the effect of inward and upward movement of the door. This not only prevents interference between the door and the cabinet below, but also reduces the length of the door extending beyond the cabinet after opening.

[0064] In some embodiments, optionally, the connection between the connecting rod assembly and the appliance body is located between the cooking cavity and the bottom of the appliance body, and the connection between the connecting rod assembly and the door body is closer to the bottom of the door body than to the top of the door body.

[0065] In this embodiment, the arrangement position of the connecting rod assembly is further defined.

[0066] The utensil body has a bottom. Along the second direction, the bottom of the utensil body is located below the cooking cavity.

[0067] The door body has a top and a bottom. Along the second direction, the top of the door body is located above the bottom of the door body.

[0068] The connection between the connecting rod assembly and the appliance body is located between the cooking cavity and the bottom of the appliance body, and the connection between the connecting rod assembly and the door body is closer to the bottom of the door body than to the top of the door body.

[0069] The linkage assembly is positioned for a drop-down door. When the door is opened, the linkage assembly deforms to drive the door in an obliquely upward direction (i.e., upward and inward) toward the appliance body. When the door is opened or closed, the linkage assembly moves the door in a first direction toward the appliance body, preventing interference with the mounting support.

[0070] In some embodiments, optionally, the hinge structure further includes: an adjusting portion, through which the elastic member is connected to the hinge shell assembly, and the adjusting portion is used to adjust an initial length of the elastic member.

[0071] In this embodiment, the composition of the hinge structure is further defined.

[0072] The hinge structure also includes an adjustment portion, through which the elastic member is connected to the hinge housing assembly. The adjustment portion can adjust the initial length of the elastic member, allowing the elastic member to have different preload forces to achieve tightness of the door closing device body and achieve hovering at different angles.

[0073] And because the hinge structure also includes an adjustment part, the hinge structure can be adapted to various types of door bodies. That is, the initial length of the elastic part can be adjusted through the adjustment part according to the weight of the door body to adjust the pre-tightening force of the elastic part in a targeted manner, so that the same hinge structure can be used in conjunction with various types of door bodies, thereby improving the applicability of the product, being beneficial to the mass production of cooking utensils, and reducing the production cost of the product.

[0074] In some embodiments, optionally, the adjustment portion includes: a fixing seat, which is provided on the hinge shell group; an adjustment rod, which is movably connected to the fixing seat and connected to the elastic member; wherein the adjustment rod can move relative to the fixing seat along the second direction.

[0075] In this embodiment, the structure of the adjustment portion is further defined.

[0076] The adjusting part includes a fixing seat and an adjusting rod.

[0077] The fixing seat is arranged on the hinge shell assembly, and the hinge shell assembly serves as a mounting carrier of the fixing seat and has the function of mounting and fixing the fixing seat.

[0078] The adjusting rod is movably connected to the fixing seat and can move relative to the fixing seat in a second direction. The adjusting rod is connected to the elastic member, and by adjusting the installation position of the adjusting rod relative to the fixing seat, the initial length of the elastic member can be indirectly adjusted to achieve the purpose of adjusting the preload force of the elastic member.

[0079] A second aspect of the present application provides a cabinet assembly, comprising: a cabinet body; and the cooking utensil according to the first aspect, wherein the cooking utensil is embedded in the cabinet body.

[0080] The cabinet assembly provided in the second aspect of the present application includes the cooking utensil in the first aspect and thus has all the beneficial effects of the cooking utensil.

[0081] Additional aspects and advantages of the present application will become apparent in the following description or may be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

The connecting rod assembly 320 is connected between the hinge housing assembly 310 and the appliance body 100. When an external force acts on the door body 200 and the door body 200 is opened, the connecting rod assembly 320 deforms as the door body 200 moves, thereby opening the door body 200 and driving the door body 200 to move in a first direction toward the appliance body 100. When the door body 200 is a drop-down door, the connecting rod assembly 320 deforms to drive the door body 200 in an obliquely upward direction (i.e., upward and inward) toward the appliance body 100. When the door body 200 is a drop-down door, the connecting rod assembly 320 deforms to drive the door body 200 in an obliquely downward direction (i.e., downward and inward) toward the appliance body 100 when the door body 200 is opened. That is, during the door opening and closing process, the connecting rod assembly 320 changes the opening trajectory and closing trajectory of the door body 200 through its own deformation.

[0117] In this way, the door body 200 does not interfere with the mounting support of the cooking appliance 10 (e.g., the cabinet body 700 of the cabinet assembly 70) during the door opening and closing process. Specifically, when the cooking appliance 10 is embedded, the door body 200 moves in a first direction toward the appliance body 100 under the action of the connecting rod assembly 320 when the door body 200 is opened and closed. Therefore, the door body 200 does not interfere with the mounting support. This adaptively reduces the installation gap between the cooking appliance 10 and the mounting support, ensuring the overall aesthetics of the appliance. Furthermore, since the installation gap between the cooking appliance 10 and the mounting support is reduced, dust and other impurities that accumulate in the gap between the cooking appliance 10 and the mounting support are reduced, which helps improve the performance of the product.

[0118] Furthermore, the hinge housing assembly 310 is provided with a first slot 312, and the connecting rod assembly 320 is provided with a second slot 328. The pull rod assembly 340 is slidably connected to the first slot 312, and the pull rod assembly 340 is slidably connected to the second slot 328. The elastic member 330 is connected between the hinge housing assembly 310 and the pull rod assembly 340.

[0119] It can be understood that the connecting rod assembly 320 is slidingly connected to either the first slide groove 312 or the second slide groove 328, and the first slide groove 312 and the second slide groove 328 cooperate with each other (such as the setting positions of the first slide groove 312 and the second slide groove 328, such as the shapes of the first slide groove 312 and the second slide groove 328) to have the function of limiting the movement trajectory of the pull rod assembly 340.

[0120] When the door body 200 is opened and is in the first open state (e.g., a small-angle open state), the rod assembly 340 slides along the first slide groove 312 and cooperates with the rod assembly 340 to slide along the second slide groove 328. The first slide groove 312 and the second slide groove 328 cooperate to limit the offset position of the rod assembly 340, thereby indirectly adjusting the deformation of the elastic member 330. That is, the length of the elastic member 330 from the connection between the hinge housing assembly 310 and the elastic member 330 to the connection between the rod assembly 340 and the elastic member 330 is adjusted to meet the requirements of the sliding door and automatic door closing load when the door body 200 is in the first open state. When the external force acting on the door body 200 is removed, the door body 200 can automatically close under the action of the elastic member 330.

[0121] When the door 200 is opened and in the second open state (e.g., a wide-angle open state), the elastic member 330 is in a stretched state, and the tension of the elastic member 330 is equal to the torque generated by the weight of the door 200, allowing the door 200 to hover at any angle. That is, the tension of the elastic member 330 matches the torque generated by the weight of the door 200, so that when the door 200 is in the second open state, after the external force acting on the door 200 is removed, the elastic member 330 has the effect of stopping the door 200 from further rotation, restricting the door 200 from rotating, and causing the door 200 to hover at a predetermined position. At this point, the door 200 will not close, and the user can freely place food into or remove food from the cooking cavity 110 of the appliance body 100, facilitating user operation.

[0122] When closing the door body 200 that is hovering in a predetermined position, the elastic member 330 switches from a stretched state to a retracted state. The sum of the external force acting on the door body 200 and the elastic tension provided by the elastic member 330 when it retracts is greater than the torque generated by the weight of the door body 200. The door body 200 can automatically close under the action of the elastic member 330.

[0123] It can be understood that the connecting rod assembly 320 is slidably connected to any one of the first slide groove 312 and the second slide groove 328. Therefore, when the door body 200 is closed, the first slide groove 312, the second slide groove 328 and the pull rod assembly 340 cooperate to limit the movement trajectory of the door body 200, so that the door body 200 can be effectively reset to the appliance body 100 to effectively close the cooking cavity 110.

[0124] Optionally, when the door body 200 is in the first open state, the door opening angle corresponding to the door body 200 is within a range greater than 0° and less than or equal to 10°.

[0125] Optionally, when the door body 200 is in the second opening state, the door body opening angle corresponding to the door body 200 is greater than 10°.

[0126] Optionally, the elastic member 330 includes a spring, a tension spring, etc., which are not listed here one by one.

[0127] In some embodiments, optionally, as Figure 11 As shown, the first sliding groove 312 includes a straight groove section 3122 and an arc section 3124 .

[0128] The arc segment 3124 is connected to the straight slot segment 3122 .

[0129] When the door 200 is in a closed state, the straight groove section 3122 extends along the height direction of the cooking utensil 10 , and the arc section 3124 bends and extends from the straight groove section 3122 toward one side of the elastic member 330 toward the utensil body 100 .

[0130] When the door body 200 is in the first open state, the connection between the pull rod assembly 340 and the first sliding groove 312 is located at the arc segment 3124 .

[0131] When the door body 200 is in the second open state, the connection between the pull rod assembly 340 and the first sliding groove 312 is located at the straight groove section 3122 .

[0132] In this embodiment, the first sliding groove 312 includes a straight groove section 3122 and an arcuate section 3124 , and the arcuate section 3124 is connected to the straight groove section 3122 . The pull rod assembly 340 can slide at the straight groove section 3122 and the arcuate section 3124 .

[0133] When the door 200 is closed, the straight slot section 3122 extends along the height of the cooking appliance 10, and the arcuate section 3124 curves and extends from the straight slot section 3122 toward the side of the elastic member 330 toward the appliance body 100. In other words, the arcuate section 3124 defines the extension direction of the first sliding slot 312 when the door 200 is closed.

[0134] Specifically, when the door 200 is in the first open state, the connection between the rod assembly 340 and the first slide groove 312 is located at the arcuate segment 3124. That is, when the door 200 is in the slightly open state, the rod assembly 340 slides along the arcuate segment 3124 and cooperates with the rod assembly 340 to slide along the second slide groove 328. The arcuate segment 3124 and the second slide groove 328 cooperate to limit the offset position of the rod assembly 340, thereby indirectly adjusting the deformation of the elastic member 330 to meet the sliding and automatic closing load requirements when the door 200 is in the first open state. It will be understood that the positioning and shapes of the arcuate segment 3124 and the second slide groove 328 cooperate to specifically adjust the offset position of the rod assembly 340 when the door 200 is opened.

[0135] Specifically, when the door body 200 is in the second open state, the connection between the pull rod assembly 340 and the first slide groove 312 is located at the straight groove section 3122. That is, when the door body 200 is in the wide-angle open state, the pull rod assembly 340 slides along the straight groove section 3122 to provide structural support for increasing the deformation of the elastic member 330. This ensures that the tension of the elastic member 330 matches the torque generated by the weight of the door body 200 when the door body 200 is in the second open state, thereby providing structural support for the door body 200 to hover at a predetermined position.

[0136] In some embodiments, optionally, the second sliding groove 328 is arranged opposite to the first sliding groove 312 .

[0137] When the door body 200 is in a closed state, the second sliding groove 328 extends obliquely. Along the appliance body 100 to the door body 200, the distance from the groove wall of the second sliding groove 328 to the bottom 210 of the door body gradually decreases.

[0138] In this embodiment, the location of the second sliding groove 328 and the shape of the second sliding groove 328 are further defined.

[0139] The second sliding groove 328 is disposed opposite to the first sliding groove 312 .

[0140] When the door body 200 is in a closed state, the second sliding groove 328 extends obliquely. Specifically, along the appliance body 100 to the door body 200, the distance from the groove wall of the second sliding groove 328 to the bottom 210 of the door body gradually decreases.

[0141] When the door 200 is in the first open state, the rod assembly 340 slides along the arcuate segment 3124. Simultaneously, the rod assembly 340 slides diagonally downward along the second slide slot 328. The arcuate segment 3124 and the second slide slot 328 cooperate to limit the offset position of the rod assembly 340, thereby indirectly adjusting the deformation of the elastic member 330 to meet the sliding and automatic closing load requirements when the door 200 is in the first open state. It will be appreciated that the positioning and shapes of the arcuate segment 3124 and the second slide slot 328 cooperate to specifically adjust the offset position of the rod assembly 340 when the door 200 is opened.

[0142] Specifically, when the door body 200 is in the second open state, the pull rod assembly 340 slides along the straight groove section 3122, and the connection between the pull rod assembly 340 and the second slide groove 328 is located at the end of the second slide groove 328 away from the appliance body 100. This setting provides structural support for increasing the deformation of the elastic member 330, so that when the door body 200 is in the second open state, the tension of the elastic member 330 can match the torque generated by the weight of the door body 200, thereby providing structural support for the door body 200 to hover at a predetermined position.

[0143] In some embodiments, optionally, as Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the hinge housing assembly 310 includes a hinge housing 314 and a fixing block 316 .

[0144] The hinge housing 314 defines a mounting cavity 3144 with an opening 3142 .

[0145] The opening 3142 is disposed opposite to the device body 100 .

[0146] A portion of the connecting rod assembly 320 is located in the mounting cavity 3144 and is rotatably connected to the hinge housing 314 .

[0147] The elastic member 330 and the pull rod assembly 340 are both disposed in the mounting cavity 3144 .

[0148] The fixing block 316 is disposed in the installation cavity 3144 , and the fixing block 316 defines a first sliding groove 312 .

[0149] In this embodiment, the structure of the hinge housing assembly 310 is further defined.

[0150] Specifically, the hinge housing assembly 310 includes a hinge housing 314 and a fixing block 316 .

[0151] The hinge housing 314 is provided with a mounting cavity 3144 having an opening 3142. The opening 3142 of the hinge housing 314 is disposed opposite to the appliance body 100. It is understood that the hinge housing 314 is a groove structure having the opening 3142. The hinge housing 314 extends along the second direction.

[0152] A portion of the connecting rod assembly 320 is located within the mounting cavity 3144 and is rotatably connected to the hinge housing 314. The elastic member 330, the pull rod assembly 340, and the fixing block 316 are all disposed within the mounting cavity 3144. In other words, the hinge housing 314 serves to mount and fix the elastic member 330, the pull rod assembly 340, and the fixing block 316. This ensures that the elastic member 330, the pull rod assembly 340, and the fixing block 316 are properly dimensioned and prevents the elastic member 330, the pull rod assembly 340, and the fixing block 316 from being exposed, thereby maintaining the aesthetic appearance of the cooking appliance 10 when the door 200 is opened or closed.

[0153] Furthermore, the fixing block 316 is provided with a first sliding groove 312 , and the fixing block 316 is slidably connected to the pull rod assembly 340 .

[0154] In some embodiments, optionally, as Figure 4 and Figure 11 As shown, the fixing block 316 includes a support plate 3162 and two vertical plates 3164 .

[0155] The two vertical plates 3164 are spaced apart and arranged on a side of the support plate 3162 facing the device body 100 .

[0156] Each vertical plate 3164 is provided with a first sliding groove 312 , and the pull rod assembly 340 is located between the two vertical plates 3164 .

[0157] The hinge structure 300 further includes two first rollers 350 and a second roller 360 .

[0158] The pull rod assembly 340 is slidably connected to the two first sliding grooves 312 of the fixing block 316 via the two first rollers 350 .

[0159] The pull rod assembly 340 is slidably connected to the second sliding groove 328 via the second roller 360 .

[0160] In this embodiment, the structure of the fixing block 316 is further defined.

[0161] The fixing block 316 includes a support plate 3162 and two vertical plates 3164. The support plate 3162 is located in the installation cavity 3144 and is connected to the hinge housing 314. The two vertical plates 3164 are both connected to the side of the support plate 3162 facing the device body 100 and are arranged at intervals.

[0162] Any one of the two vertical plates 3164 is provided with a first sliding groove 312 , and the first sliding grooves 312 of the two vertical plates 3164 are arranged opposite to each other.

[0163] The pull rod assembly 340 is located between the two vertical plates 3164 . It can be understood that the pull rod assembly 340 is accommodated in the space enclosed by the two vertical plates 3164 and the support plate 3162 .

[0164] The hinge structure 300 also includes two first rollers 350, through which the rod assembly 340 is slidably connected to the two first slots 312 of the fixed block 316. That is, each first roller 350 is slidably connected to a first slot 312 on a vertical plate 3164, and the rod assembly 340 slides along the first slots 312 of the fixed block 316 via the two first rollers 350. This arrangement increases the contact area and contact angle between the rod assembly 340 and the fixed block 316, ensuring balanced and consistent force on the rod assembly 340 and enabling stable sliding of the rod assembly 340 along the first slots 312.

[0165] The cooking appliance 10 further includes a second roller 360 , through which the rod assembly 340 is slidably connected to the second slide groove 328 of the connecting rod assembly 320 . That is, the rod assembly 340 slides along the second slide groove 328 of the connecting rod assembly 320 via the second roller 360 .

[0166] The first roller 350 is in sliding engagement with the first slide groove 312 , and the second roller 360 is in sliding engagement with the second slide groove 328 . This arrangement can ensure smooth movement of the pull rod assembly 340 and avoid jamming.

[0167] In some embodiments, optionally, as Figure 4 、 Figure 6 、 Figure 8 and Figure 10As shown, the pull rod assembly 340 comprises a first pull rod 342 and a second pull rod 344.

[0168] The first pull rod 342 connects the two first rollers 350 and the second roller 360.

[0169] The second pull rod 344 is connected between the first pull rod 342 and the elastic member 330.

[0170] In this embodiment, the structure of the pull rod assembly 340 is further defined.

[0171] Specifically, the pull rod assembly 340 comprises the first pull rod 342 and the second pull rod 344.

[0172] The first pull rod 342 connects the two first rollers 350 and the second roller 360. That is, the first pull rod 342 serves as a mounting carrier of the two first rollers 350 and the second roller 360, and has the function of mounting and fixing the two first rollers 350 and the second roller 360.

[0173] The second pull rod 344 is connected between the first pull rod 342 and the elastic member 330, that is, the first pull rod 342 and the elastic member 330 are connected through the second pull rod 344.

[0174] In some other embodiments, the pull rod assembly 340 comprises one pull rod.

[0175] In some other embodiments, the pull rod assembly 340 comprises at least three pull rods. For example, the pull rod assembly 340 comprises four pull rods, five pull rods, and the like, which are not listed one by one. When the door body 200 is in the closed state, the plurality of pull rods are connected in sequence along the second direction.

[0176] In some embodiments, optionally, the connecting rod assembly 320, the appliance body 100 and the hinged shell group 310 form a quadrilateral structure.

[0177] In this embodiment, the cooperation structure of the connecting rod assembly 320, the appliance body 100 and the hinged shell group 310 is further defined.

[0178] Specifically, the connecting rod assembly 320, the appliance body 100 and the hinged shell group 310 form a quadrilateral structure. When an external force acts on the door body 200, the door body 200 is opened, and the quadrilateral structure is deformed to achieve the purpose of driving the door body 200 to move along the first direction towards the appliance body 100.

[0179] It can be understood that the connecting rod assembly 320, the appliance body 100 and the hinge shell assembly 310 form a quadrilateral structure, which has a tensile limit and a shortening limit. The deformation of the connecting rod assembly 320 can indirectly limit the switching limit positions of the door body 200 and the appliance body 100, ensure the effective matching dimensions of the door body 200 and the appliance body 100, and ensure the reliability and stability of the door body 200 in opening and closing the cooking cavity 110.

[0180] In some embodiments, optionally, as Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the linkage assembly 320 includes a hinge arm 322 , a first link 324 , and two second links 326 .

[0181] The hinge arm 322 is disposed on the device body 100 .

[0182] The first connecting rod 324 defines a slot 3242 and a second sliding groove 328 .

[0183] A portion of the hinge arm 322 is inserted into the slot 3242 and is rotatably connected to the first connecting rod 324 .

[0184] The first connecting rod 324 is rotatably connected to the hinge housing assembly 310 .

[0185] The hinge arm 322 is rotatably connected between the two second connecting rods 326 .

[0186] Each second link 326 is rotatably connected to the hinge housing assembly 310 .

[0187] When the door body 200 is in the closed state, along the second direction, the position of the first connecting rod 324 is higher than the position of the second connecting rod 326 .

[0188] In this embodiment, the structure of the connecting rod assembly 320 is further defined.

[0189] Specifically, the link assembly 320 includes a hinge arm 322 , a first link 324 , and two second links 326 .

[0190] The hinge arm 322 is provided on the device body 100 , that is, the device body 100 serves as a mounting carrier of the hinge arm 322 and has the function of mounting and fixing the junction arm.

[0191] The first connecting rod 324 has a slot 3242 and a second slot 328 . A portion of the hinge arm 322 is inserted into the slot 3242 and rotatably connected to the first connecting rod 324 . The first connecting rod 324 is rotatably connected to the hinge housing 310 . The second slot 328 is located on one side of the slot 3242 .

[0192] Any one of the two second links 326 is rotatably connected to the hinge arm 322, and the hinge arm 322 is located between the two second links 326. Any one of the two second links 326 is rotatably connected to the hinge housing assembly 310.

[0193] It can be seen that the hinge arm 322 , the first connecting rod 324 , the two second connecting rods 326 , the device body 100 and the hinge housing assembly 310 form a quadrilateral structure.

[0194] The first connecting rod 324 has a first end and a second end, and the second connecting rod 326 has a third end and a fourth end. The first end is rotatably connected to the hinge arm 322, and the second end is rotatably connected to the hinge housing assembly 310. The third end is rotatably connected to the hinge arm 322, and the fourth end is rotatably connected to the hinge housing assembly 310.

[0195] The following takes the door body 200 as an example of a pull-down door body.

[0196] Specifically, when the door body 200 is in the closed state, along the second direction, the position of the first connecting rod 324 is higher than the position of the second connecting rod 326 .

[0197] Specifically, when the door 200 switches from a closed state to an open state, the second connecting rod 326 is tilted. The distance between the third end of the second connecting rod 326 and the bottom of the cooking utensil 10 is shorter than the distance between the fourth end of the second connecting rod 326 and the bottom of the cooking utensil 10. In other words, the second connecting rod 326 is tilted upward, so that the movement trajectory of the second connecting rod 326 causes the fourth end to gradually move closer to the cooking utensil body 100, thereby driving the door 200 closer to the cooking utensil body 100, ultimately achieving the inward and upward movement of the door 200. This prevents interference between the door 200 and the cabinet 700 below, while also reducing the length of the door 200 extending beyond the cabinet 700 after opening.

[0198] In some embodiments, optionally, as Figures 1 to 3 As shown, the connection between the connecting rod assembly 320 and the appliance body 100 is located between the cooking cavity 110 and the bottom 120 of the appliance body, and the connection between the connecting rod assembly 320 and the door body 200 is closer to the bottom 210 of the door body than to the top 220 of the door body.

[0199] In this embodiment, the arrangement position of the connecting rod assembly 320 is further defined.

[0200] The utensil body 100 has a bottom. Along the second direction, the bottom 120 of the utensil body is located below the cooking cavity 110.

[0201] The door body 200 has a top and a bottom. Along the second direction, the top 220 of the door body is located above the bottom 210 of the door body.

[0202] The connection between the connecting rod assembly 320 and the appliance body 100 is located between the cooking cavity 110 and the bottom 120 of the appliance body. The connection between the connecting rod assembly 320 and the door body 200 is closer to the bottom 210 of the door body than to the top 220 of the door body.

[0203] The location of the connecting rod assembly 320 is suitable for a pull-down door 200. When the door 200 is opened, the connecting rod assembly 320 deforms to drive the door 200 in an obliquely upward direction (i.e., upward and inward) toward the appliance body 100. When the door 200 is opened or closed, the connecting rod assembly 320 moves the door 200 in a first direction toward the appliance body 100, thereby preventing interference between the door 200 and the mounting support.

[0204] In some embodiments, optionally, as Figure 4 As shown, the hinge structure 300 further includes an adjustment portion 370 .

[0205] The elastic member 330 is connected to the hinge housing assembly 310 via the adjusting portion 370 . The adjusting portion 370 is used to adjust the initial length of the elastic member 330 .

[0206] In this embodiment, the composition of the hinge structure 300 is further defined.

[0207] The hinge structure 300 also includes an adjustment portion 370, through which the elastic member 330 is connected to the hinge housing assembly 310. The adjustment portion 370 can adjust the initial length of the elastic member 330. This allows the elastic member 330 to have different preload forces, thereby ensuring that the door 200 closes the appliance body 100 more tightly and allowing the door to hover at different angles.

[0208] And because the hinge structure 300 also includes an adjustment part 370, the hinge structure 300 can be adapted to various models of door bodies 200. That is, the initial length of the elastic member 330 can be adjusted through the adjustment part 370 according to the weight of the door body 200, so as to adjust the pre-tightening force of the elastic member 330 in a targeted manner, so that the same hinge structure 300 can be used in conjunction with various models of door bodies 200, thereby improving the applicability of the product, facilitating the mass production of the cooking appliance 10, and reducing the production cost of the product.

[0209] In some embodiments, optionally, as Figure 4 、 Figure 6 、 Figure 8 andFigure 10 As shown, the adjustment portion 370 includes a fixing seat 372 and an adjustment rod 374 .

[0210] The fixing base 372 is disposed on the hinge housing assembly 310 .

[0211] The adjusting rod 374 is movably connected to the fixing base 372 , and the adjusting rod 374 is connected to the elastic member 330 .

[0212] The adjusting rod 374 can move relative to the fixing seat 372 along the second direction.

[0213] In this embodiment, the structure of the adjustment portion 370 is further defined.

[0214] The adjusting portion 370 includes a fixing seat 372 and an adjusting rod 374 .

[0215] The fixing seat 372 is disposed on the hinge housing assembly 310 . The hinge housing assembly 310 serves as a mounting carrier for the fixing seat 372 and has the function of mounting and fixing the fixing seat 372 .

[0216] The adjustment rod 374 is movably connected to the fixing base 372 and is movable in a second direction relative to the fixing base 372. The adjustment rod 374 is connected to the elastic member 330. By adjusting the installation position of the adjustment rod 374 relative to the fixing base 372, the initial length of the elastic member 330 can be indirectly adjusted to adjust the preload force of the elastic member 330.

[0217] Optionally, the adjustment rod 374 is slidably connected to the fixing seat 372. Specifically, the adjustment rod 374 can slide relative to the mounting hole of the fixing seat 372 along the length direction of the elastic member 330, thereby allowing the length of the adjustment rod 374 extending from the fixing seat 372 to be adjusted.

[0218] Optionally, the fixing seat 372 is fixed on the door body 200 , wherein the fixing seat 372 can be directly installed on the door body 200 or installed on the door body 200 through other structures.

[0219] like Figure 1 、 Figure 2 and Figure 3 As shown, a cabinet assembly 70 according to some embodiments of the present application includes: a cabinet body 700; and a cooking utensil 10 as in any of the above embodiments, wherein the cooking utensil 10 is embedded in the cabinet body 700.

[0220] The cabinet assembly 70 of the present application includes the cooking utensil 10 of any of the above embodiments and thus has all the beneficial effects of the cooking utensil 10 .

[0221] It is understandable that Figure 2The first direction arrow in FIG indicates that when the door body 200 is a pull-down door body, the door body 200 is opened and the connecting rod assembly 320 is deformed to drive the movement direction of the door body 200. The arrow only represents the movement direction, not the movement angle. The movement angle of the door body 200 includes but is not limited to Figure 2 The tilt angle of the arrow in .

[0222] Optionally, the cooking appliance 10 includes any one of an oven, a steamer, a steam oven, a microwave oven, an air fryer, and a microwave air fryer.

[0223] Alternatively, a built-in drop-down door hinge mechanism can be designed. During the opening and closing process of the built-in oven drop-down door, the bottom of the door body 200 can achieve a change of track (the bottom of the entire door body moves upward and inward), rather than a pivoting movement. This ensures that the door body 200 does not interfere with the cabinet when the gap is small. At the same time, it also ensures the door's hovering and smooth movement when opening and closing.

[0224] The present application reasonably arranges the structure of the cooking appliance 10 so that when the door 200 is opened or closed, the door 200 moves in a variable trajectory, and the door 200 does not interfere with the cabinet 700 of the cabinet assembly 70 and can hover.

[0225] Optionally, the cooking appliance 10 includes a appliance body 100, a door 200, and a hinge structure 300. The hinge structure 300 includes a hinge housing 314, a fixing block 316, a connecting rod assembly 320, an elastic member 330, a pull rod assembly 340, a first roller 350, a second roller 360, an adjustment portion 370, a countersunk pin 400, a connecting pin 500, and a sleeve 600. The connecting rod assembly 320 includes a hinge arm 322, a first connecting rod 324, and two second connecting rods 326. The pull rod assembly 340 includes a first pull rod 342 and a second pull rod 344.

[0226] The hinge shell 314 is connected to the door body 200 of the built-in oven. The hinge shell 314 is nested on the door body 200 and is fixed by screws.

[0227] The hinge arm 322 is nested in the appliance body 100 and its movement is limited by a stop block.

[0228] The first connecting rod 324 is rotatably connected to the hinge housing 314 and the hinge arm 322 via a connecting pin 500 .

[0229] The second link 326 is rotatably connected to the hinge housing 314 and the hinge arm 322 via a connecting pin 500 .

[0230] The first pull rod 342 is connected to the first connecting rod 324 via the connecting pin 500 . When the door is opened, the first pull rod 342 slides along the first sliding groove 312 .

[0231] The second pull rod 344 is connected to the pin 500 to connect the first pull rod 342 and the elastic member 330 (eg, the elastic member 330 includes a tension spring), and the second pull rod 344 moves following the first pull rod 342 .

[0232] The tension spring connects the second pull rod 344 and the hinge housing 314 via the connecting pin 500 , and the tension spring extends or retracts as the second pull rod 344 moves.

[0233] The fixing block 316 is used to limit the movement trajectory of the first pull rod 342 .

[0234] The first roller 350 is connected to the first pull rod 342 via the connecting pin 500 , and the first roller 350 is slidably connected to the first sliding groove 312 .

[0235] The second roller 360 is connected to the first pull rod 342 via a connecting pin 500 , and the second roller 360 is slidably connected to the second sliding groove 328 .

[0236] The shaft sleeve 600 is nested in the hinge arm 322 and is fixed by the connecting pin 500 .

[0237] The adjusting rod 374 can adjust the end position and initial length of the tension spring. The adjusting rod 374 is fixed to the hinge housing 314 through the fixing seat 372 .

[0238] The fixing base 372 is fixed on the hinge housing 314 .

[0239] The hinge housing 314 is fixed to the metal bracket of the door body 200 by screws. The hinge arm 322 is nested and constrained on the front plate of the appliance body 100. The hinge arm 322 and the hinge housing 314 are connected to the first connecting rod 324 and the two second connecting rods 326 by connecting pins 500.

[0240] The door body 200 and the appliance body 100 are connected in an openable and closable manner via a hinge structure 300. The hinge structure 300 can satisfy the door body 200 to perform a track-changing rotational motion relative to the appliance body 100 within a range of 0° to 90°.

[0241] When the angle of opening and closing the door is less than or equal to 10°, the second roller 360 slides left and right in the second slide groove 328 of the first connecting rod 324, and cooperates with the first pull rod 342 to slide on the fixed block 316, so as to adjust the elongation of the tension spring to meet the sliding door and automatic closing load requirements when the door body 200 is in the first open state, and match the small-angle automatic locking function (i.e., automatic closing function).

[0242] like Figure 8 and Figure 10 As shown, after the door opening and closing angle is greater than 10°, the second roller 360 is located at the rightmost side of the second sliding groove 328 .

[0243] When the door 200 is open, the spring tension provided by the extended spring on the hinge structure 300 is equal to the torque generated by the weight of the door 200, allowing the door 200 to hover at any angle. When the door 200 is closed, the spring tension provided by the retracted spring is greater than the torque generated by the weight of the door 200, allowing the door 200 to close automatically.

[0244] The connecting rod assembly 320, the appliance body 100, and the hinge housing assembly 310 form a quadrilateral structure. This quadrilateral deformation principle allows the bottom 210 of the door body to move upward and inward, rather than along a fixed axis. This ensures that the door body 200 does not interfere with the cabinet body 700 during opening and closing, while also ensuring smooth movement of the door body 200 during opening and closing.

[0245] The cooking appliance 10 includes a main body 100, a door 200 and a hinge structure 300. The main body 100 is provided with a cooking cavity 110. The door 200 and the main body 100 are openably connected via the hinge structure 300. The door 200 is used to open or close the cooking cavity 110.

[0246] The hinge structure 300 includes a hinge housing assembly 310 , a connecting rod assembly 320 , an elastic member 330 and a pull rod assembly 340 .

[0247] The hinge housing assembly 310 is provided on the door body 200 . The door body 200 serves as a mounting carrier for the hinge housing assembly 310 and has the function of mounting and fixing the hinge housing assembly 310 .

[0248] The connecting rod assembly 320 is connected to the hinge housing assembly 310, and the connecting rod assembly 320 is connected to the appliance body 100. The connecting rod assembly 320 is connected between the hinge housing assembly 310 and the appliance body 100. When an external force acts on the door body 200 and the door body 200 is opened, the connecting rod assembly 320 deforms as the door body 200 moves, thereby opening the door body 200 and driving the door body 200 to move in a first direction toward the appliance body 100. When the door body 200 is a drop-down door, the connecting rod assembly 320 deforms to drive the door body 200 in an obliquely upward direction (i.e., upward and inward) toward the appliance body 100. When the door body 200 is a drop-down door, the connecting rod assembly 320 deforms to drive the door body 200 in an obliquely downward direction (i.e., downward and inward) toward the appliance body 100 when the door body 200 is opened. That is, during the door opening and closing process, the connecting rod assembly 320 changes the opening trajectory and closing trajectory of the door body 200 through its own deformation.

[0249] In this way, the door body 200 does not interfere with the mounting support of the cooking appliance 10 (e.g., the cabinet body 700 of the cabinet assembly 70) during the door opening and closing process. Specifically, when the cooking appliance 10 is embedded, the door body 200 moves in a first direction toward the appliance body 100 under the action of the connecting rod assembly 320 when the door body 200 is opened and closed. Therefore, the door body 200 does not interfere with the mounting support. This adaptively reduces the installation gap between the cooking appliance 10 and the mounting support, ensuring the overall aesthetics of the appliance. Furthermore, since the installation gap between the cooking appliance 10 and the mounting support is reduced, dust and other impurities that accumulate in the gap between the cooking appliance 10 and the mounting support are reduced, which helps improve the performance of the product.

[0250] Furthermore, the hinge housing assembly 310 is provided with a first slot 312, and the connecting rod assembly 320 is provided with a second slot 328. The pull rod assembly 340 is slidably connected to the first slot 312, and the pull rod assembly 340 is slidably connected to the second slot 328. The elastic member 330 is connected between the hinge housing assembly 310 and the pull rod assembly 340.

[0251] It can be understood that the connecting rod assembly 320 is slidingly connected to either the first slide groove 312 or the second slide groove 328, and the first slide groove 312 and the second slide groove 328 cooperate with each other (such as the setting positions of the first slide groove 312 and the second slide groove 328, such as the shapes of the first slide groove 312 and the second slide groove 328) to have the function of limiting the movement trajectory of the pull rod assembly 340.

[0252] When the door body 200 is opened and is in the first open state (e.g., a small-angle open state), the rod assembly 340 slides along the first slide groove 312 and cooperates with the rod assembly 340 to slide along the second slide groove 328. The first slide groove 312 and the second slide groove 328 cooperate to limit the offset position of the rod assembly 340, thereby indirectly adjusting the deformation of the elastic member 330. That is, the length of the elastic member 330 from the connection between the hinge housing assembly 310 and the elastic member 330 to the connection between the rod assembly 340 and the elastic member 330 is adjusted to meet the requirements of the sliding door and automatic door closing load when the door body 200 is in the first open state. When the external force acting on the door body 200 is removed, the door body 200 can automatically close under the action of the elastic member 330.

[0253] When the door 200 is opened and in the second open state (e.g., a wide-angle open state), the elastic member 330 is in a stretched state, and the tension of the elastic member 330 is equal to the torque generated by the weight of the door 200, allowing the door 200 to hover at any angle. That is, the tension of the elastic member 330 matches the torque generated by the weight of the door 200, so that when the door 200 is in the second open state, after the external force acting on the door 200 is removed, the elastic member 330 has the effect of stopping the door 200 from further rotation, restricting the door 200 from rotating, and causing the door 200 to hover at a predetermined position. At this point, the door 200 will not close, and the user can freely place food into or remove food from the cooking cavity 110 of the appliance body 100, facilitating user operation.

[0254] When closing the door body 200 that is hovering in a predetermined position, the elastic member 330 switches from a stretched state to a retracted state. The sum of the external force acting on the door body 200 and the elastic tension provided by the elastic member 330 when it retracts is greater than the torque generated by the weight of the door body 200. The door body 200 can automatically close under the action of the elastic member 330.

[0255] It can be understood that the connecting rod assembly 320 is slidably connected to any one of the first slide groove 312 and the second slide groove 328. Therefore, when the door body 200 is closed, the first slide groove 312, the second slide groove 328 and the pull rod assembly 340 cooperate to limit the movement trajectory of the door body 200, so that the door body 200 can be effectively reset to the appliance body 100 to effectively close the cooking cavity 110.
