Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a cooking utensil and a cabinet. Background Art

[0002] At present, when existing built-in cooking appliances are installed in cabinets of customized sizes, the hinge installed between the door body and the box body is a fixed shaft. During the process of opening and closing the door, the door body rotates downward around the shaft. In order to avoid interference between the door body and the cabinet body, the customized cabinet body will sink a certain distance to avoid interference with the cabinet body when the door body rotates. This leads to a large gap between the cooking appliance and the cabinet body, thereby affecting the overall appearance of the cooking appliance and the cabinet body. In addition, the larger gap will bring problems such as easy accumulation of dust and difficulty in cleaning. Utility Model Content

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

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

[0006] In view of this, the utility model proposes a cooking utensil, comprising: a box body, provided with an opening; a door body, movably connected to the box body, for opening or closing the opening; a hinge mechanism, comprising: a hinge arm, provided on the door body; a hinge seat, provided on the box body, located on one side of the opening along a first direction; an elastic component, provided on the hinge seat and connected to the hinge arm, for driving the hinge seat to move during the process of the door body closing the opening; a first connecting rod and a second connecting rod, wherein the two ends of the first connecting rod are respectively rotatably connected to the hinge seat and the hinge arm, and the two ends of the second connecting rod are respectively rotatably connected to the hinge seat and the hinge arm, wherein, during the process of the door body opening the opening, the first connecting rod and the second connecting rod drive the door body to move along the first direction to the other side of the opening through the hinge arm.

[0007] The cooking appliance provided by the present invention comprises a housing, a door, and a hinge mechanism, wherein the hinge mechanism comprises a hinge arm, a hinge seat, an elastic component, and a first connecting rod and a second connecting rod. The elastic component is disposed within the hinge seat, the hinge arm is connected to the door, and the hinge seat is connected to the housing, so that the door rotates relative to the housing via the hinge mechanism to open and close the opening. Furthermore, by arranging the hinge arm on the door and the hinge seat on the housing, the space occupied by the hinge mechanism on the door is reduced, the connection structure between the hinge arm and the door is simplified, and the overall weight of the door is reduced. Furthermore, during the closing process of the door, the elastic component can pull the door to move via the hinge arm, providing assistance for closing the door. Among them, the hinge arm and the hinge seat are rotatably connected through the joint action of the first connecting rod and the second connecting rod, so that the door body no longer rotates around the fixed axis, and then in the process of the door body opening the opening, the first connecting rod and the second connecting rod can drive the door body to move along the first direction toward the other side of the opening through the hinge arm, that is, the door body is lifted in the direction close to the opening, thereby avoiding interference with the cabinet and other mounting structures during the rotation of the door body. Therefore, there is no need to sink the cabinet to provide the space required for the door body to rotate in the first direction, and the gap between the door body and the cabinet can be set to be relatively small, so that the gap between the door body and the cabinet is not easy to accumulate dust and is easy to clean, thereby improving the integrity between the cooking utensils and the cabinet, and meeting the smoothness of the door movement during the opening and closing process.

[0008] The cooking appliance provided by the present invention may also have the following additional technical features:

[0009] In some embodiments, optionally, the first connecting rod includes a first end and a second end, and the second connecting rod includes a third end and a fourth end; the first end and the third end are both rotatably connected to the hinge seat, and along the first direction, the rotation axis of the first end is located on the side of the rotation axis of the third end close to the opening, and the second end and the fourth end are both rotatably connected to the hinge arm, wherein the door body has a first opening angle, and when the door body closes the opening, along the first direction, the rotation axis of the second end is located on the side of the rotation axis of the fourth end close to the opening; when the door body is at the first opening angle, along the first direction, the rotation axis of the second end is located on the side of the rotation axis of the fourth end away from the opening.

[0010] In this embodiment, the first connecting rod includes a first end and a second end, the first end being rotatably connected to the hinge base and the second end being rotatably connected to the hinge arm; the second connecting rod includes a third end and a fourth end, the third end being rotatably connected to the hinge base and the fourth end being rotatably connected to the hinge arm. Along a first direction, a rotation axis between the first end and the hinge base is located on a side of a rotation axis between the third end and the hinge base closer to the opening. During opening and closing of the door, the positions of the second end and the fourth end move with the door. Specifically, when the door is closed, the rotation axis of the second end is located on a side of a rotation axis of the fourth end closer to the opening. When the door is at a first opening angle, the rotation axis between the second end and the hinge arm is located on a side of a rotation axis between the fourth end and the hinge arm farther from the opening. That is, during the process of the door switching from the closed opening state to the first opening angle, the bottom of the door, in addition to rotating to open the opening, can also move toward the side closer to the opening driven by the fourth end of the second connecting rod, thereby enabling the door to avoid external structures such as a cabinet during opening. The cooking appliance proposed in the present application has a movement trajectory formed by the door body under the mutual restriction of the first connecting rod and the second connecting rod, so that the end of the door body connected to the box body can at least move in the direction of avoiding the cabinet body.

[0011] In some embodiments, optionally, when the door body closes the opening, the distance between the rotation axis of the third end and the rotation axis of the fourth end along the second direction is a first distance; when the door body is at a first opening angle, the distance between the rotation axis of the third end and the rotation axis of the fourth end along the second direction is a second distance, and the second distance is smaller than the first distance.

[0012] In this embodiment, the first distance is greater than the second distance, that is, in the process of the door body switching to the first opening angle, driven by the first connecting rod and the second connecting rod, the end of the hinge arm connected to the first connecting rod and the second connecting rod moves along the second direction toward the side closer to the opening, that is, in the process of the door body switching to the first opening angle, the end of the door body connected to the box body can move toward the direction closer to the box body, thereby reducing the overall length of the cooking appliance along the second direction when the door body is open, so as to facilitate users to take and place ingredients.

[0013] In some embodiments, optionally, the first link and the second link are located on opposite sides of the hinge arm.

[0014] In this embodiment, the first link and the second link are located on opposite sides of the hinge arm, thereby avoiding interference between the first link and the second link during their rotation, thereby ensuring the reliability of the hinge mechanism in unfolding and folding.

[0015] Optionally, both ends of the first connecting rod and both ends of the second connecting rod are rotatably connected to the hinge seat and the hinge arm through pins.

[0016] In some embodiments, optionally, the elastic component includes: a first elastic member, which is provided at the hinge seat, and one end of the first elastic member is connected to the hinge seat; a pull rod, which is provided at the hinge seat, and the two ends of the pull rod are respectively connected to the hinge arm and the other end of the first elastic member, and the hinge arm can drive the first elastic member to deform through the pull rod so that the door body can hover at at least one second opening angle, and the second opening angle is smaller than the first opening angle of the door body; wherein, when the door body is at the first opening angle, the first elastic member is in a stretched state, and in the process of the door body switching to a closed opening, the first elastic member can restore the deformation to drive the door body to close the opening.

[0017] In this embodiment, the elastic component includes a pull rod and a first elastic member, wherein the pull rod is arranged on the hinge seat and is rotatably connected to the hinge arm, and the first elastic member is arranged on the hinge seat and is rotatably connected to the other end of the pull rod, wherein the pull rod can move within the hinge seat under the action of the hinge arm and the first elastic member, and when the hinge arm moves relative to the hinge seat so that the door body switches to the first opening angle, the hinge arm drives the pull rod to move so that the first elastic member stretches, and then when the spring tension provided by the first elastic member is equal to the torque generated by the weight of the door body, the door body is suspended at the second opening angle. In the process of closing the door body, the first elastic member provides tension when retracting, thereby providing assistance for the closing of the door body. At the same time, when the spring tension provided by the first elastic member is greater than the torque generated by the weight of the door body, the door body can be automatically closed.

[0018] In some embodiments, optionally, the elastic component also includes: a second elastic member, provided on the pull rod; the door body also has a third opening angle, and when the door body is at the third opening angle, the second elastic member contacts the hinge arm; in the process of the door body switching from the third opening angle to the closed opening, the hinge arm pushes at least a portion of the second elastic member to compress, so as to provide assistance for the door body to close the opening.

[0019] In this embodiment, the elastic component also includes a second elastic member, which is arranged on the pull rod. When the door body is at the third opening angle, the second elastic member contacts the hinge arm. In the process of the door body switching from the third opening angle to the closed opening, the hinge arm gradually squeezes the second elastic member, causing a part of the second elastic member to deform, and then the reverse thrust generated by the second elastic member acts on the hinge arm, so that the hinge arm drives the door body to close the opening. That is, the setting of the second elastic member provides an assist for the door body to close the opening, thereby realizing automatic locking of the door body in the process of switching from the third opening angle to the closed opening.

[0020] In some embodiments, optionally, the second elastic member includes: a power-assisting rod, which is provided on the pull rod and movably connected to the pull rod; a rolling portion, which is provided at one end of the power-assisting rod close to the hinge arm, and the second elastic member contacts the hinge arm through the rolling portion; an elastic portion, which is provided on the power-assisting rod, and the end of the elastic portion close to the hinge arm is limited by the power-assisting rod, and the end of the elastic portion away from the hinge arm is limited by the pull rod. When the door body is at a third opening angle, the rolling portion is in contact with the hinge arm, and when the door body closes the opening, the elastic portion is in a compressed state.

[0021] In this embodiment, the second elastic member includes a power-assisting rod, a rolling portion, and an elastic portion. The power-assisting rod is provided on the pull rod and can be movably connected to the pull rod. The rolling portion is provided at the end of the power-assisting rod close to the hinge arm. The elastic portion is provided on the power-assisting rod, and the end of the elastic portion close to the hinge arm is engaged with the power-assisting rod limiter, while the end of the elastic portion away from the hinge arm is engaged with the pull rod limiter. When the door body switches from the third opening angle to the closed opening, the hinge arm contacts the rolling portion and squeezes the power-assisting rod through the rolling portion, causing the power-assisting rod to move in a direction away from the hinge arm, thereby compressing the elastic portion. The reverse thrust of the elastic portion is used to assist the door body in closing, thereby realizing the automatic locking function of the door body. At the same time, the provision of the rolling portion reduces the friction between the second elastic member and the hinge arm, thereby reducing the wear of the hinge arm and increasing the service life of the hinge arm.

[0022] In some embodiments, optionally, the hinge arm is provided with a cam structure, and the cam structure contacts the rolling portion to push the rolling portion to move.

[0023] In this embodiment, a cam structure is provided on the hinge arm. During the rotation of the hinge arm, the rolling portion is squeezed by the cam structure, thereby causing the elastic portion to deform, thereby providing assistance for closing the door body.

[0024] In some embodiments, optionally, the number of the hinge mechanisms is at least two, and the at least two hinge mechanisms are arranged at intervals along the third direction.

[0025] In this embodiment, the number of hinge mechanisms is at least two, and at least two hinge mechanisms are arranged at intervals along the third direction, so that the door body is connected to the box body through at least two hinge mechanisms, thereby improving the connection strength between the door body and the box body. At the same time, during the opening and closing process of the door body, the movement trajectories of the two ends are the same and the opening and closing process of the door is smoother.

[0026] According to a second aspect of the present invention, a cabinet is provided, comprising: a cabinet body; and a cooking utensil as provided in any one of the above embodiments, wherein the cooking utensil is embedded in the cabinet body.

[0027] The cabinet provided in the second aspect of the present invention includes the cooking utensil proposed in any of the above embodiments and thus has all the beneficial effects of the cooking utensil.

[0048] The cooking utensil provided by the present invention includes a box body 1, a door body 2 and a hinge mechanism 3, and the hinge mechanism 3 includes a hinge arm 30, a hinge seat 31, an elastic component 32 and a first connecting rod 33 and a second connecting rod 34. An elastic component 32 is provided in the hinge seat 31, the hinge arm 30 is connected to the door body 2, and the hinge seat 31 is connected to the box body 1, so that the door body 2 rotates relative to the box body 1 through the hinge mechanism 3 to realize the opening and closing of the opening 10. In addition, the hinge arm 30 is arranged on the door body 2, and the hinge seat 31 is arranged on the box body 1, which can reduce the space occupied by the hinge mechanism 3 on the door body 2, and can also simplify the connection structure between the hinge arm 30 and the door body 2 and reduce the overall weight of the door body 2. At the same time, in the process of closing the door body 2, the elastic component 32 can pull the door body 2 to move through the hinge arm 30, providing assistance for the closing of the door body 2. Among them, Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, the hinge arm 30 and the hinge seat 31 are rotationally connected through the joint action of the first connecting rod 33 and the second connecting rod 34, so that the door body 2 no longer rotates around the fixed axis, and then in the process of the door body 2 opening the opening 10, the first connecting rod 33 and the second connecting rod 34 can drive the door body 2 to move along the first direction toward the other side of the opening 10 through the hinge arm 30, that is, the door body 2 is lifted in the direction close to the opening 10, thereby avoiding interference with the cabinet and other mounting structures during the rotation of the door body 2. Therefore, there is no need to sink the cabinet to provide the space required for the door body 2 to rotate in the first direction, and the gap between the door body 2 and the cabinet can be set to be relatively small, so that the gap between the door body 2 and the cabinet is not easy to accumulate dust and is easy to clean, thereby improving the integrity between the cooking utensils and the cabinet, and meeting the smoothness of the movement of the door body 2 during the opening and closing process.

[0049] Optionally, in the process of switching the door body 2 from a closed opening 10 to an open opening 10, the elastic component 32 is stretched, thereby achieving the suspension of the door body 2 to realize operations such as dehumidification and exhaust of food in the box body 1; in the process of switching the door body 2 from an open opening 10 to a closed opening 10, the elastic component 32 restores its deformation, thereby driving the door body 2 to move through the hinge arm 30, providing assistance for the closing of the door body 2.

[0050] Optionally, the door body 2 can be a drop-down door structure, that is, the hinge mechanism 3 connects the bottom of the box body 1 and the bottom of the door body 2, so that the door body 2 flips downward to open the opening 10; the door body 2 can also be a side-opening door structure, that is, the door body 2 is rotatably connected to the box body 1 through the hinge mechanism 3 at one end along the length or width.

[0051] like Figures 1 to 8As shown, in some embodiments, optionally, the first connecting rod 33 includes a first end 330 and a second end 332, and the second connecting rod 34 includes a third end 340 and a fourth end 342; the first end 330 and the third end 340 are both rotatably connected to the hinge seat 31, and along the first direction, the rotation axis A of the first end 330 is located on the side of the rotation axis C of the third end 340 close to the opening 10, and the second end 332 and the fourth end 342 are both rotatably connected to the hinge arm 30, wherein the door body 2 has a first opening angle, and when the door body 2 closes the opening 10, along the first direction, the rotation axis B of the second end 332 is located on the side of the rotation axis D of the fourth end 342 close to the opening 10; when the door body 2 is at the first opening angle, along the first direction, the rotation axis B of the second end 332 is located on the side of the rotation axis D of the fourth end 342 away from the opening 10.

[0052] In this embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the first connecting rod 33 includes a first end 330 and a second end 332. The first end 330 is rotatably connected to the hinge base 31, and the second end 332 is rotatably connected to the hinge arm 30. The second connecting rod 34 includes a third end 340 and a fourth end 342. The third end 340 is rotatably connected to the hinge base 31, and the fourth end 342 is rotatably connected to the hinge arm 30. Along the first direction, the rotation axis A between the first end 330 and the hinge base 31 and the rotation axis C between the third end 340 and the hinge base 31 are located on the side close to the opening 10. During the opening and closing process of the door body 2, the positions of the second end 332 and the fourth end 342 move with the door body 2. Specifically, when the door body 2 closes the opening 10, the rotation axis B of the second end 332 is located on the side close to the opening 10 of the rotation axis D of the fourth end 342, as shown in FIG. Figure 7 、 Figure 8 、 Figure 11 and Figure 12 As shown, when the door body 2 is at the first opening angle, the rotation axis B between the second end 332 and the hinge arm 30 is located on the side of the rotation axis D between the fourth end 342 and the hinge arm 30 away from the opening 10. That is, when the door body 2 switches from the state of closing the opening 10 to the first opening angle, the bottom of the door body 2 can not only rotate to open the opening 10, but also move toward the side closer to the opening 10 under the drive of the fourth end 342 of the second connecting rod 34, thereby allowing the door body 2 to avoid external structures such as the cabinet during the opening process. In the cooking appliance proposed in this application, the movement trajectory of the door body 2 formed by the mutual restriction of the first connecting rod 33 and the second connecting rod 34 enables at least the end of the door body 2 connected to the cabinet 1 to move in a direction to avoid the cabinet.

[0053] Optionally, the first opening angle is a state where the door body 2 is fully opened.

[0054] Optionally, Figure 5 and Figure 6 The intermediate state of the door body 2 during the opening process is shown. It can be seen that the door body 2 switches from the state of closing the opening 10 to the state of Figure 5 and Figure 6 During the process of the door body 2 opening the opening 10, the hinge mechanism 3 is Figure 3 and Figure 4 The state changes to Figure 5 and Figure 6 and then switch to Figure 7 and Figure 8 state, thereby making the door body 2 at the first opening angle.

[0055] In some embodiments, optionally, as Figure 2 and Figure 4 As shown, when the door body 2 closes the opening 10, the distance between the rotation axis C of the third end 340 and the rotation axis D of the fourth end 342 along the second direction is a first distance L1; Figure 8 As shown, when the door body 2 is at the first opening angle, the distance between the rotation axis C of the third end 340 and the rotation axis D of the fourth end 342 along the second direction is a second distance L2, which is smaller than the first distance L1.

[0056] In this embodiment, the first distance L1 is greater than the second distance L2, that is, in the process of the door body 2 switching to the first opening angle, driven by the first connecting rod 33 and the second connecting rod 34, the end of the hinge arm 30 connected to the first connecting rod 33 and the second connecting rod 34 moves along the second direction toward the side close to the opening 10, that is, in the process of the door body 2 switching to the first opening angle, the end of the door body 2 connected to the box body 1 can move toward the direction close to the box body 1, thereby reducing the overall length of the cooking utensil along the second direction when the door body 2 is open, so as to facilitate users to take and place food.

[0057] Optionally, the door body 2 is a drop-down door structure. When the door body 2 closes the opening 10, the second connecting rod 34 is tilted from the third end 340 to the fourth end 342 toward the bottom of the box body 1. When the door body 2 is at the first opening angle, the second connecting rod 34 is tilted from the third end 340 to the fourth end 342 toward the top of the box body 1.

[0058] Optionally, when the door body 2 is a pull-down door structure, the inclination angle of the second connecting rod 34 relative to the second direction when the door body 2 closes the opening 10 is smaller than the inclination angle of the second connecting rod 34 relative to the second direction when the door body 2 is at the first opening angle, so that during the opening of the door body 2, driven by the first connecting rod 33 and the second connecting rod 34, the door body 2 can move both toward the top of the box body 1 and into the inside of the box body 1, thereby saving the space required for the rotation of the door body 2.

[0059] Optionally, the first end 330 is located on a side of the third end 340 close to the door body 2 along the second direction.

[0060] Optionally, when the door body 2 closes the opening 10, the rotation axis B of the second end 332 is located along the second direction on the side of the rotation axis D of the fourth end 342 away from the box body 1; in the case of the first opening angle, the rotation axis B of the second end 332 is located along the second direction on the side of the rotation axis D of the fourth end 342 away from the box body 1.

[0061] In some embodiments, optionally, the first link 33 and the second link 34 are located on opposite sides of the hinge arm 30 .

[0062] In this embodiment, the first link 33 and the second link 34 are located on opposite sides of the hinge arm 30, thereby avoiding interference between the first link 33 and the second link 34 during their rotation, thereby ensuring the reliability of the hinge mechanism 3 in unfolding and folding.

[0063] Optionally, both ends of the first connecting rod 33 and both ends of the second connecting rod 34 are rotatably connected to the hinge seat 31 and the hinge arm 30 through pins.

[0064] like Figure 2 、 Figure 3 、 Figure 5 and Figure 7 As shown, in some embodiments, optionally, the elastic component 32 includes: a first elastic member 320, which is provided on the hinge seat 31, and one end of the first elastic member 320 is connected to the hinge seat 31; a pull rod 322, which is provided on the hinge seat 31, and the two ends of the pull rod 322 are respectively connected to the hinge arm 30 and the other end of the first elastic member 320, and the hinge arm 30 can drive the first elastic member 320 to deform through the pull rod 322 so that the door body 2 hovers at at least one second opening angle, and the second opening angle is smaller than the first opening angle of the door body 2; wherein, when the door body 2 is at the first opening angle, the first elastic member 320 is in a stretched state, and in the process of the door body 2 switching to close the opening 10, the first elastic member 320 can restore the deformation to drive the door body 2 to close the opening 10.

[0065] In this embodiment, the elastic assembly 32 includes a pull rod 322 and a first elastic member 320. The pull rod 322 is disposed on the hinge base 31 and is rotatably connected to the hinge arm 30. The first elastic member 320 is disposed on the hinge base 31 and is rotatably connected to the other end of the pull rod 322. The pull rod 322 is movable within the hinge base 31 under the action of the hinge arm 30 and the first elastic member 320. When the hinge arm 30 moves relative to the hinge base 31 to switch the door body 2 to the first opening angle, the hinge arm 30 drives the pull rod 322 to move, causing the first elastic member 320 to stretch. When the spring tension provided by the first elastic member 320 equals the torque generated by the weight of the door body 2, the door body 2 is suspended at the second opening angle. During the closing process of the door body 2, the first elastic member 320 provides a pulling force when it retracts, thereby assisting the closing of the door body 2. Furthermore, when the spring tension provided by the first elastic member 320 exceeds the torque generated by the weight of the door body 2, the door body 2 can automatically close.

[0066] It can be understood that the second opening angle can be multiple.

[0067] Optionally, the first elastic member 320 may be a spring, a spring, elastic rubber, etc.

[0068] It is understandable that the second opening angle and the first opening angle can be set according to actual conditions.

[0069] Optionally, the first opening angle is the angle that the door body 2 rotates from the state of closing the opening 10 to the first opening angle. Optionally, the first opening angle is greater than or equal to 90°.

[0070] like Figure 2 、 Figure 3 、 Figure 5 and Figure 7 As shown, in some embodiments, optionally, the elastic component 32 also includes: a second elastic member 324, which is provided on the pull rod 322; the door body 2 also has a third opening angle, and when the door body 2 is at the third opening angle, the second elastic member 324 contacts the hinge arm 30; in the process of the door body 2 switching from the third opening angle to the closed opening 10, the hinge arm 30 pushes at least a portion of the second elastic member 324 to be compressed, so as to provide assistance to the door body 2 to close the opening 10.

[0071] In this embodiment, the elastic component 32 also includes a second elastic member 324, which is arranged on the pull rod 322. When the door body 2 is at the third opening angle, the second elastic member 324 contacts the hinge arm 30. In the process of the door body 2 switching from the third opening angle to the closed opening 10, the hinge arm 30 gradually squeezes the second elastic member 324, causing a part of the second elastic member 324 to deform, and then the reverse thrust generated by the second elastic member 324 acts on the hinge arm 30, so that the hinge arm 30 drives the door body 2 to close the opening 10, that is, the setting of the second elastic member 324 provides assistance to the door body 2 in closing the opening 10, thereby realizing automatic locking of the door body 2 in the process of switching from the third opening angle to the closed opening 10.

[0072] like Figure 3 and Figure 5 As shown, in some embodiments, optionally, the second elastic member 324 includes: a power-assisting rod 3240, which is provided on the pull rod 322 and movably connected to the pull rod 322; a rolling portion 3242, which is provided at one end of the power-assisting rod 3240 close to the hinge arm 30, and the second elastic member 324 is in contact with the hinge arm 30 through the rolling portion 3242; an elastic portion 3244, which is provided on the power-assisting rod 3240, and the end of the elastic portion 3244 close to the hinge arm 30 is limitedly matched with the power-assisting rod 3240, and the end of the elastic portion 3244 away from the hinge arm 30 is limitedly matched with the pull rod 322, when the door body 2 is at the third opening angle, the rolling portion 3242 is in contact with the hinge arm 30, and when the door body 2 closes the opening 10, the elastic portion 3244 is in a compressed state.

[0073] In this embodiment, the second elastic member 324 includes a power rod 3240, a rolling portion 3242 and an elastic portion 3244. The power rod 3240 is arranged on the pull rod 322 and can be movably connected with the pull rod 322. The rolling portion 3242 is arranged on the end of the power rod 3240 close to the hinge arm 30. The elastic portion 3244 is arranged on the power rod 3240, and the end of the elastic portion 3244 close to the hinge arm 30 is limited to the power rod 3240. The elastic portion 3244 is away from the hinge. One end of the link arm 30 engages with the pull rod 322 in a limiting manner. When the door body 2 switches from the third opening angle to close the opening 10, the hinge arm 30 contacts the rolling portion 3242, which compresses the assist rod 3240, causing the assist rod 3240 to move away from the hinge arm 30. This in turn compresses the elastic portion 3244. The reverse thrust of the elastic portion 3244 assists the closing of the door body 2, thereby achieving the automatic locking function of the door body 2. Furthermore, the provision of the rolling portion 3242 reduces the friction between the second elastic member 324 and the hinge arm 30, thereby reducing the wear of the hinge arm 30 and increasing the service life of the hinge arm 30.

[0074] Optionally, a slide groove and a limiting baffle are provided in the pull rod 322, a through hole is provided in the limiting baffle, and the power rod 3240 is provided in the slide groove, passes through the through hole and can move in the through hole.

[0075] Optionally, both ends of the elastic portion 3244 are free ends. When the door body 2 is at the third opening angle, the two ends of the elastic portion 3244 are in contact with the pull rod 322 and the power rod 3240 respectively to achieve positioning of the two ends of the elastic portion 3244.

[0076] Optionally, the third opening angle can be set according to actual conditions. For example, the third opening angle is less than or equal to 10°, that is, when the door body 2 switches from the state of closing the opening 10 to the third opening angle, the rotation angle is less than or equal to 10°.

[0077] like Figure 3 and Figure 5 As shown, in some embodiments, optionally, the hinge arm 30 is provided with a cam structure 302 , and the cam structure 302 contacts the rolling portion 3242 to push the rolling portion 3242 to move.

[0078] In this embodiment, a cam structure 302 is provided on the hinge arm 30. During the rotation of the hinge arm 30, the rolling portion 3242 is squeezed by the cam structure 302, thereby causing the elastic portion 3244 to deform, thereby providing assistance for closing the door body 2.

[0079] Optionally, when the door body 2 closes the opening 10 , the rolling portion 3242 contacts the highest point of the cam structure 302 .

[0080] In some embodiments, optionally, the number of the hinge mechanisms 3 is at least two, and the at least two hinge mechanisms 3 are arranged at intervals along the third direction.

[0081] In this embodiment, the number of hinge mechanisms 3 is at least two, and at least two hinge mechanisms 3 are arranged at intervals along the third direction, so that the door body 2 is connected to the box body 1 through at least two hinge mechanisms 3, thereby improving the connection strength between the door body 2 and the box body 1. At the same time, during the opening and closing process of the door body 2, the movement trajectories of the two ends are the same and the opening and closing process of the door is smoother.

[0082] Optionally, the first direction, the second direction and the third direction are perpendicular to each other.

[0083] Optionally, the first direction is the height direction of the box body 1 , the second direction is the width direction of the box body 1 (eg, the front-to-back direction), and the third direction is the length direction of the box body 1 (eg, the left-to-right direction).

[0084] According to an embodiment of the present invention, a cabinet is provided, comprising: a cabinet body; and a cooking utensil as provided in any of the above embodiments, wherein the cooking utensil is embedded in the cabinet body.

[0085] The cabinet provided by the present invention includes the cooking utensil proposed in any of the above embodiments and thus has all the beneficial effects of the cooking utensil.

[0086] According to one embodiment of the present application, to improve the convenience of movement during the opening and closing process of a built-in pull-down door oven, the pull-down door track-changing hinge mechanism 3 allows the door body 2 to hover without interfering with the cabinet during the opening and closing process. The hinge mechanism 3 includes a hinge housing (e.g., a hinge seat 31), a hinge arm 30, a first connecting rod 33, a second connecting rod 34, a pull rod 322, a tension spring (e.g., a first elastic member 320), a roller (e.g., a rolling portion 3242), a compression spring (e.g., an elastic portion 3244), a power rod 3240, and a connecting pin. The connection relationship is as follows:

[0087] Hinge housing: connected to the door body 2 of the built-in oven, nested on the door body 2, and fixed with screws.

[0088] Hinge arm 30: nested on the box body 1 and restricted in movement by a limit block.

[0089] The first connecting rod 33 is connected to the hinge housing and the hinge arm 30 via a connecting pin to perform rotational motion.

[0090] The second connecting rod 34 connects the hinge housing and the hinge arm 30 via a connecting pin to perform rotational motion.

[0091] Pull rod 322: connected to hinge arm 30 and tension spring via connecting pin, pull rod 322 moves with hinge housing when door is opened.

[0092] Extension spring: connects the pull rod 322 and the hinge housing via a connecting pin, and extends or retracts as the pull rod 322 moves.

[0093] Roller: It is located on the power rod 3240 and contacts the hinge arm 30 to perform rolling compression and rebound compression spring.

[0094] Compression spring: compresses and rebounds in the sliding groove on the pull rod 322 following the roller.

[0095] Assist rod 3240 : A compression spring is sleeved on the assist rod 3240 , and the assist rod 3240 can move on the pull rod 322 .

[0096] Among them, the hinge shell is fixed to the box body 1 by screws, the hinge arm 30 is nested and fixed to the door body 2, and the hinge arm 30 and the hinge shell are connected to the first connecting rod 33 and the second connecting rod 34 by connecting pins. In this way, the box body 1 and the door body 2 are connected through the entire hinge mechanism 3, and the door body 2 performs a track-changing rotation movement in the range of 0°-90° relative to the box body 1 through the hinge mechanism 3. When the opening and closing angle of the door is less than 10° (for example, when the door body 2 switches between the closed opening 10 and the third opening angle), the compression spring contacts the hinge arm 30 and compresses to provide reverse thrust, thereby realizing the adjustment of the door opening load size and the automatic locking function at a small angle.

[0097] When the door body 2 is opening the opening 10, the spring tension provided by the extension spring on the hinge mechanism 3 is equal to the torque generated by the weight of the door body 2, so that the door body 2 can hover at any angle. When the door body 2 is closing the opening 10, the spring tension provided by the retraction spring is greater than the torque generated by the weight of the door body 2, so that the door body 2 can automatically close.

[0098] A quadrilateral structure is finally formed by the first connecting rod 33 and the second connecting rod 34 and the door body 2 and the hinge shell on the hinge arm 30. The quadrilateral deformation principle satisfies the biaxial rotation movement of the connecting rod, and the upward and inward track movement of the bottom of the door body 2 is realized instead of the fixed axis movement, so that the door body 2 does not interfere with the cabinet during the door opening and closing process, and at the same time, the movement smoothness of the door body 2 during the door opening and closing process is also satisfied.

[0099] The hinge mechanism 3 proposed in this application is suitable for a built-in pull-down door oven.
