Description

Technical Field

[0001] This utility model relates to the field of cooking device technology, and in particular to a door opening and closing component of a cooking device and a cooking device. Background Technology

[0002] Currently, cooking appliances typically heat the interior of the cooking chamber through an internal heating structure. During the heating process, the door on the cooking appliance must be fully closed before the internal heating structure can be opened; otherwise, burns or heat loss may occur.

[0003] The door of a cooking appliance is primarily locked to the appliance via an opening and closing mechanism. In some related technologies, this mechanism involves a door hook that locks or disengages from the appliance. To ensure automatic unlocking after the door is closed and prevent burns from manual unlocking after cooking, a drive mechanism, typically powered by a motor, is usually installed inside the cooking appliance to unlock the door hook.

[0004] However, since the drive structure, unlocking structure, and locking structure are all assembled on the same end face, the required assembly space is relatively large, resulting in a relatively long transmission path and a relatively low unlocking speed. Furthermore, the cooking device generates significant internal heat during cooking, which can easily damage the motor. Utility Model Content

The first end face is provided with an elastic component, one end of which is connected to the mounting bracket and the other end of which is connected to the locking member, and provides elastic stress to drive the locking member to move closer to the locking position.

[0013] As an optional implementation, the mounting bracket is provided with a guide groove, the locking member is provided with a guide post, the guide groove extends along the rotation direction of the locking member, and the guide post is slidably connected to the guide groove.

[0025] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0026] See Figure 1-10 This utility model discloses a door opening and closing assembly for a cooking device, including a door 30 and a locking mechanism 20, with a first locking part 10 provided on the door 30. The locking mechanism 20 includes a mounting bracket 24, a driving member, a locking member 22, and an unlocking member 21. The mounting bracket 24 is provided with a first end face 241 and a second end face 244, which are opposite to each other. A locking position, a locking member 22, and an unlocking member 21 are provided on the first end face 241. The locking member 22 can move closer to or away from the locking position and locks with the first locking part 10 when it is in the locking position. The unlocking member 21 is provided with a linkage end 211 and an unlocking end.

[0027] See Figure 3 as well as Figure 7 The driving component includes a drive motor 23, a transmission component 26, and a guide component. The transmission component 26 is mounted on the second end face 244. One end of the transmission component 26 is connected to the rotating shaft 231 of the drive motor, and the other end of the transmission component 26 is connected to the bottom end of the guide component. The top end of the transmission component 26 passes through the first end face 241 and is connected to the linkage end 211. The guide component is slidably engaged with the mounting bracket 24 and guides the unlocking end to move closer to or away from the locking component 22 when the transmission component 26 rotates. The unlocking end is used to press against the locking component 22 after moving closer to it, so as to drive the locking component 22 away from the locked position.

[0028] It should be noted that the body of the drive motor 23 can be assembled to the first end face 241, and the shaft 231 of the drive motor can extend to the second end face 244 and connect with the transmission component 26.

[0029] Based on the above structure, when using the door 30 opening and closing assembly of this utility model, the door 30 opening and closing structure can be used in cooking equipment, such as microwave ovens, ovens, microwave-steam-grill combination ovens, etc. The mounting bracket 24 of the locking mechanism 20 is installed on the cooking body 40, and the door 30 can be installed on the cooking body 40 for closing or opening the cooking opening of the cooking body 40.

[0030] When the cooking body 40 is cooking, the door 30 can be closed to the cooking opening of the cooking body 40. When the door is closed, the first locking part 10 on the door can extend into the locking position on the mounting bracket 24 of the cooking body 40, and the locking member 22 can move close to the locking position. The locking member 22 can then maintain the locking state with the first locking part 10 at the locking position. In this way, the door 30 can be kept closed under the locking action of the locking member 22 and the first locking part 10.

[0031] When the door 30 is opened, the locking member 22 and the first locking part 10 need to be unlocked. At this time, the drive motor 23 is started, and the shaft 231 of the drive motor can drive the transmission member 26. When the transmission member 26 rotates, since the end of the transmission member 26 is rotatably connected to the guide member, and the guide member is in sliding fit with the mounting bracket 24, the transmission motion of the transmission member 26 can be converted into linear motion output by the sliding fit between the guide member and the mounting bracket 24. In this way, the unlocking member 21 connected to the guide member can move closer to the locking member 22 under the guidance of the guide member. After the stage end of the unlocking member 21 moves closer to the locking member 22, it can press against the locking member 22 and drive the locking member 22 away from the locked position. In this way, the locking member 22 can be disengaged from the first locking part 10 under the action of the unlocking member 21, realizing unlocking. The door 30 can be opened at this time, completing automatic unlocking.

[0032] Furthermore, the rotational motion of the transmission component 26, in conjunction with the action of the guide component, guides the unlocking component 21 to move in a straight line. The rotational transmission may slip or elastically deform under overload, forming a natural buffer to prevent damage to the locking mechanism 20.

[0033] It should be noted that in this application, both the locking element 22 and the unlocking element 21 are installed on the first end face 241 of the mounting bracket 24, while the drive motor 23 and the transmission element 26 are assembled on the second end face 244 and linked by the guide element. In this way, the unlocking motion trajectory of the unlocking element 21 and the rotational motion trajectory of the transmission element 26 can be on the two end faces of the mounting bracket 24. Compared with the related technology, which requires considering the interference of two motion trajectories when the unlocking element 21 and the transmission element 26 are set on the same end face, and requires maintaining a certain distance on the same end face of the mounting bracket 24 during assembly to avoid interference, this application does not need to consider the interference of the motion trajectories of the unlocking element 21 and the transmission element 26. Therefore, the assembly space required for assembling the locking mechanism 20 can be effectively reduced, and the transmission trajectory of the transmission element 26 and the motion trajectory of the unlocking element 21 can partially overlap, resulting in shorter transmission time and higher unlocking efficiency.

[0034] Of course, after the door 30 is opened, the locking member 22 and the first locking part 10 are unlocked. The drive motor 23 can drive the unlocking member 21 away from the locking member 22, and the locking member 22 can move closer to the locking position and return to the locking position, so that the first locking part 10 can extend into the locking position to lock when the door 30 is closed next time.

[0035] As an optional implementation, see [link to implementation details]. Figure 7 The transmission component 26 includes a first swing arm 261 and a second swing arm 262. One end of the first swing arm 261 is connected to the shaft 231 of the drive motor, and the other end of the first swing arm 261 is connected to one end of the second swing arm 262. The other end of the second swing arm 262 is connected to the guide. Thus, when the unlocking component 21 is unlocked, the shaft 231 of the drive motor drives the first swing arm 261 to rotate, and the first swing arm 261 can drive the second swing arm 262 to swing. The swing of the second swing arm 262 is guided by the sliding of the guide and the mounting bracket 24, so it can drive the guide to slide, thereby realizing the unlocking action.

[0036] If the linear sliding of the guide is driven by the rotation of a single swing arm, the force point of the swing arm is the connection point between the single swing arm and the guide. After long-term use, jamming is likely to occur. In this embodiment, the force in the transmission process is shared equally by two swing arms. The radial components generated by the two swing arms are equal in magnitude and opposite in direction, directly canceling each other out. In this way, the force at the connection point with the guide is in a linear direction, the linear movement of the guide is stable, and it is not easy to wobble. Therefore, jamming during the unlocking process can be effectively reduced.

[0037] As an optional implementation, a limit switch 28 can also be provided on the second end face 244. The limit switch 28 is installed on the side of the drive motor 23. The unlocking action is completed when the first swing arm 261 swings to the position where it touches the touch switch. When the drive motor 23 drives the first swing arm 261 to rotate, the first swing arm 261 can touch the limit switch 28 when it rotates to its maximum length position. The limit switch 28 can then send a stop signal, the drive motor 23 stops moving, and the unlocking action is completed.

[0038] The limit switch 28 is located on the side of the drive motor 23, so that after the first swing arm 261 swings 90°, the first swing arm 261 can touch the limit switch 28. In this way, the first swing arm 261 can control the drive motor 23 to stop in time and complete the unlocking when the swing time is short, thus the unlocking time is short.

[0039] As an optional implementation, a sliding groove 243 can be provided on the mounting bracket 24, and the sliding groove 243 extends from the first end face 241 to the second end face 244. The guide is slidably connected to the sliding groove 243. In this way, the top end of the guide is hinged to the linkage end 211 of the unlocking member 21, and the bottom end of the guide is hinged to the transmission member 26. Thus, the sliding of the guide in the sliding groove 243 can convert the rotational motion of the transmission member 26 into the linear motion of the unlocking member 21, thereby realizing the unlocking action.

[0040] Of course, the aforementioned sliding groove 243 can be implemented using a strip-shaped perforated structure from related technologies.

[0041] More specifically, the aforementioned guide includes a guide post 221, the bottom end of which is rotatably connected to the end of the second swing arm 262, and the top end of which is rotatably connected to the linkage end 211. Thus, the second swing arm 262 and the linkage end 211 of the unlocking member 21 can be connected via the guide post 221. Specifically, a sliding plane is provided on the outer surface of the guide post 221 to slide against the side wall of the sliding groove 243, preventing swaying during sliding.

[0042] As an optional implementation, during assembly, the mounting bracket 24 is assembled to the cooking body 40, with the second end face 244 of the mounting bracket 24 facing the cooking cavity 41. To prevent the high heat inside the cooking cavity 41 from causing thermal impact on the drive motor 23, a heat insulation baffle 27 can also be provided on the second end face 244. Connecting protrusions 271 are provided on both sides of the heat insulation baffle 27, and the connecting protrusions 271 are connected to the mounting bracket 24 to space the heat insulation baffle 27 from the second end face 244, forming an installation gap. The drive motor 23 and the transmission component 26 are installed in the installation gap. In this way, the heat insulation baffle 27 covers the bottom of the drive motor 23, blocking the heat from the cooking body 40 from directly affecting the drive motor 23 and improving the service life of the drive motor 23.

[0043] As an optional implementation, see [link to implementation details]. Figure 3 , Figure 4 as well as Figure 5 One end of the locking member 22 is rotatably connected to the mounting bracket 24, and the other end of the locking member 22 is provided with a second locking part 222. The unlocking member 21 can press against the locking member 22 after moving close to the locking member 22, so as to drive the second locking part 222 away from the locking position.

[0044] More specifically, an elastic member 25 is provided on the first end face 241 of the mounting bracket 24. One end of the elastic member 25 is connected to the mounting bracket 24, and the other end of the elastic member 25 is connected to the locking member 22, and provides elastic stress to drive the locking member 22 to move closer to the locking position. In this way, under the action of the elastic member 25, the second locking part 222 of the locking member 22 can be kept in the state close to the locking position.

[0045] When the door 30 is closed, the door 30 is sealed in the cooking body 40 under the action of external force. Under the action of external force, the first locking part 10 extends into the locking position. The first locking part 10 can first push against the second locking part 222. At this time, the elastic member 25 is compressed. After the first locking part 10 is in place and corresponds to the second locking part 222 of the locking member 22, the elastic member 25 resets and drives the second locking part 222 to stay close to the locking position and lock to the first locking part 10, maintaining the locked state. The locked state is stable.

[0046] When unlocking, the unlocking member 21 can press against the locking member 22, causing the locking member 22 to rotate away from the locking position. When it moves away from the locking position, the second locking part 222 can disengage from the first locking part 10 at the locking position, thus completing the unlocking. During this unlocking process, the elastic member 25 is compressed, which facilitates the reset of the locking member 22.

[0047] Since the second locking part 222 disengages from the first locking part 10 by rotation, that is, by disengaging along an arc trajectory, it can gradually push the first locking part 10 along the tangent of the arc trajectory during rotation, achieving rapid disengagement and making the unlocking action smoother.

[0048] As an optional implementation, a guide groove 242 can be provided on the mounting bracket 24, and a guide post 221 can be provided on the locking member 22. The guide groove 242 extends along the rotation direction of the locking member 22, and the guide post 221 is slidably connected to the guide groove 242. In this way, when the locking member 22 rotates, the guide post 221 slides in the guide groove 242. The locking and unlocking process of the locking member 22 is stable and not easy to deviate, so the unlocking and locking can be completed accurately.

[0049] As an optional implementation, two locking members 22 are provided, with the two locking members 22 spaced apart. The position between the two locking members 22 can be the locking position. When locking, the two locking members 22 can lock on both sides of the first locking part 10, so that the locking state is more stable.

[0050] When there are two locking elements 22, the unlocking element 21 can move between the two locking elements 22, while the locking position is located between the two locking elements 22.

[0051] It should be noted that in some implementation structures, the first locking part 10 can be a locking plate, and the second locking part 222 can be a latch. Locking openings are provided on both sides of the locking plate. When the locking plate extends into the locking position, the latch can approach the locking plate and lock in the locking opening.

[0052] A pressing block 212 can also be provided at the end of the unlocking member 21. The outer diameter of the pressing block 212 can be larger than the outer diameter of the unlocking member 21. In this way, after the unlocking member 21 moves close to the locking member 22, the pressing block 212 has a larger contact area. Under the pressing action of the pressing block 212, the locking member 22 is more likely to be disengaged from the first locking part 10, and the unlocking action is faster.

[0053] Specifically, a pressure slope can be provided on the locking member 22. The pressing block 212 is used to press the pressure slope after approaching the locking member 22. The pressure slope can decompose the longitudinal force into the transverse force, making it easier to drive the locking member 22 to disengage from the first locking part 10.

[0054] Based on the structure of having two locking members 22, when the unlocking member 21 unlocks, the pressing block 212 of the unlocking member 21 can simultaneously press the pressure slope of the two locking members 22, thus completing the unlocking action of the two locking members 22 at the same time.

[0055] Example 2, See Figures 1-10 This embodiment provides a cooking device, including a cooking body 40 and a door 30 opening and closing assembly; the cooking body 40 is provided with a cooking cavity 41 and a cooking opening, and a clearance position is provided at the top of the cooking cavity 41; a mounting bracket 24 is installed on the cooking body 40 and located above the clearance position; the door 30 is rotatably connected to the cooking body 40 to open or close the cooking opening.

[0056] When the cooking body 40 is cooking, the door 30 can be closed to the cooking opening of the cooking body 40. When the door is closed, the first locking part 10 on the door can extend into the locking position on the mounting bracket 24 of the cooking body 40, and the locking member 22 can move close to the locking position. The locking member 22 can then maintain the locking state with the first locking part 10 at the locking position. In this way, the door 30 can be kept closed under the locking action of the locking member 22 and the first locking part 10.

[0057] When the door 30 is opened, the locking member 22 and the first locking part 10 need to be unlocked. At this time, the drive motor 23 is started, and the shaft 231 of the drive motor can drive the transmission member 26. When the transmission member 26 rotates, since the end of the transmission member 26 is rotatably connected to the guide member, and the guide member is in sliding fit with the mounting bracket 24, the transmission motion of the transmission member 26 can be converted into linear motion output by the sliding fit between the guide member and the mounting bracket 24. In this way, the unlocking member 21 connected to the guide member can move closer to the locking member 22 under the guidance of the guide member. After the stage end of the unlocking member 21 moves closer to the locking member 22, it can press against the locking member 22 and drive the locking member 22 away from the locked position. In this way, the locking member 22 can be disengaged from the first locking part 10 under the action of the unlocking member 21, realizing unlocking. The door 30 can be opened at this time, completing automatic unlocking.

[0058] Furthermore, the rotational motion of the transmission component 26, in conjunction with the action of the guide component, guides the unlocking component 21 to move in a straight line. The rotational transmission may slip or elastically deform under overload, forming a natural buffer to prevent damage to the locking mechanism 20.

[0059] It should be noted that in this application, both the locking element 22 and the unlocking element 21 are installed on the first end face 241 of the mounting bracket 24, while the drive motor 23 and the transmission element 26 are assembled on the second end face 244 and linked by the guide element. In this way, the unlocking motion trajectory of the unlocking element 21 and the rotational motion trajectory of the transmission element 26 can be on the two end faces of the mounting bracket 24. Compared with the related technology, which requires considering the interference of two motion trajectories when the unlocking element 21 and the transmission element 26 are set on the same end face, and requires maintaining a certain distance on the same end face of the mounting bracket 24 during assembly to avoid interference, this application does not need to consider the interference of the motion trajectories of the unlocking element 21 and the transmission element 26. Therefore, the assembly space required for assembling the locking mechanism 20 can be effectively reduced, and the transmission trajectory of the transmission element 26 and the motion trajectory of the unlocking element 21 can partially overlap, resulting in shorter transmission time and higher unlocking efficiency.

[0060] Of course, after the door 30 is opened, the locking member 22 and the first locking part 10 are unlocked. The drive motor 23 can drive the unlocking member 21 away from the locking member 22, and the locking member 22 can move closer to the locking position and return to the locking position, so that the first locking part 10 can extend into the locking position to lock when the door 30 is closed next time.

[0061] Specifically, during assembly, the second end face 244 of the mounting bracket 24 faces the cooking cavity 41, so the drive motor 23 and transmission component 26 on the second end face 244 will face the cooking cavity 41. In this embodiment, by setting a clearance at the top of the cooking cavity 41, the installation of the drive motor 23 and transmission component 26 can be avoided. Since the unlocking component 21, locking component 22, drive motor 23, and transmission component 26 on the two end faces of the mounting bracket 24 have an installation height after being assembled to the cooking body 40, a clearance recess 42 can be set to avoid the drive motor 23 and transmission component 26, reducing the installation height.
