[0043] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0044] Combine the following Figures 1 to 8 , describing an embodiment of the utility model.
[0045] According to an embodiment of the utility model, a cooking device is provided, such as Figures 1 to 5As shown, it includes a box body 1, a box door 2, a door arm 3 and a limiting assembly 4, wherein the box body 1 has an opening 11, the box door 2 is rotatably connected to the box body 1, the box door 2 is used to open or close the opening 11, one end of the door arm 3 is connected to the box door 2, and the other end is slidably matched with the box body 1, the door arm 3 is configured to limit the rotation of the box door 2 by sliding, and the limiting assembly 4 includes a driving member 41 and a limiting member 42, the driving member 41 and the limiting member 42 are transmission-connected to drive the limiting member 42 to move to a first position or a second position, when in the first position, the limiting member 42 abuts against the door arm 3 to lock the door arm 3, and when in the second position, the limiting member 42 is separated from the door arm 3 to unlock the door arm 3.
[0046] The cooking device of this embodiment is provided with a limit component 4, and the driving member 41 and the limit component 42 of the limit component 4 are transmission connected. When the cooking device is working normally, the driving member 41 drives the limit component 42 to move to the first position, that is, the limit component 42 and the door arm 3 are abutted to lock the door arm 3. At this time, the door arm 3 cannot slide, thereby limiting the rotation of the box door 2 relative to the box body 1, which can effectively prevent children from accidentally touching and opening the box door 2, thereby ensuring the safety of use. When the cooking device needs to be opened, the driving member 41 drives the limit component 42 to move to the second position, that is, the limit component 42 and the door arm 3 are separated to unlock the door arm 3. At this time, rotating the box door 2 can drive the door arm 3 to slide, thereby opening the opening 11 of the box body 1.
[0047] It can be understood that the cooking device of the present embodiment may specifically be a microwave oven or an oven, etc. Of course, in other embodiments, the cooking device may also be other cooking appliances having the relevant structure of the present embodiment.
[0048] In this embodiment, a food cooking cavity is provided in the box body 1, and the food cooking cavity is communicated with the opening 11, and food is placed in the food cooking cavity or taken out of the food cooking cavity through the opening 11.
[0049] Specifically, the box body 1 can be a rectangular box, and the opening 11 is a rectangular opening. Accordingly, the box door 2 is a rectangular door, and the size of the box door 2 is larger than the size of the opening 11, so as to completely cover the opening 11, ensure the heating heat of the cooking device, and ensure cooking safety.
[0050] In terms of the specific connection method, the box door 2 and the box body 1 can be rotatably connected through a structure such as a rotating shaft or a hinge. Specifically, the box door 2 and the box body 1 can be rotatably connected at the bottom, and the rotation between the box door 2 and the box body 1 can be achieved by pulling the box door 2 up and down. The box door 2 and the box body 1 can be rotatably connected at the side, and the rotation between the box door 2 and the box body 1 can be achieved by pulling the box door 2 left and right.
[0051] The door arm 3 can slide relative to the box body 1 when the box door 2 rotates relative to the box body 1. Conversely, when the sliding of the door arm 3 is limited, the box door 2 can no longer rotate relative to the box body 1.
[0052] In addition to the above configuration, in some embodiments, Figure 3 and Figure 5 As shown, the cooking device further comprises a hinge assembly 5, which is fixedly connected to the cabinet 1, and the other end of the door arm 3 is hinged to the hinge assembly 5 and can slide relative to the hinge assembly 5. The hinge assembly 5 is fixedly connected to the cabinet 1, and plays a role of sliding support for the door arm 3. At the same time, the door arm 3 can adaptively rotate and slide relative to the hinge assembly 5 when the cabinet door 2 rotates.
[0053] Specifically, the hinge assembly 5 includes a hinge seat 51, an elastic member 52 and a guide wheel 53, wherein the hinge seat 51 is fixedly connected to the box body 1, one end of the elastic member 52 is connected to the hinge seat 51, and the other end is connected to an end of the door arm 3 away from the box door 2, and the guide wheel 53 is rotatably set on the hinge seat 51, and the bottom of the door arm 3 is slidably matched with the guide wheel 53.
[0054] According to the above arrangement, when the door 2 is opened, the door 2 rotates and drives the bottom of the door arm 3 to slide along the guide wheel 53. At the same time, the door arm 3 stretches the elastic member 52. The door arm 3 is pulled by the elastic member 52, so that the door arm 3 is always pressed on the guide wheel 53, so that the two can be reliably matched. The guide wheel 53 can also reduce the friction, thereby reducing the resistance when the door 2 rotates, and the movement of the door arm 3 will in turn limit the rotation of the door 2. When the door 2 needs to be closed, the elastic force of the elastic member 52 can achieve quick closing of the door 2, and the operation is labor-saving.
[0055] The hinge seat 51 includes a hinge body 511 and a connecting plate 512, wherein the hinge body 511 is arranged along the height direction of the box body 1, the guide wheel 53 is rotatably arranged on the side of the hinge body 511 close to the box door 2, the elastic member 52 is connected to the side of the hinge body 511 away from the box door 2, and the connecting plate 512 is arranged at the bottom of the hinge body 511 and fixedly connected to the box body 1. In this arrangement, the guide wheel 53 and the elastic member 52 are connected and supported by the hinge body 511, and the connecting plate 512 is connected and supported by the hinge body 511, so as to realize the connection of the door arm 3 with the box body 1 through the hinge assembly 5.
[0056] Specifically, the hinge body 511 can be an L-shaped plate, the guide wheel 53 is set at the top of the L-shaped plate through a rotating shaft, and the elastic member 52 is connected to the bottom of the L-shaped plate through a hook. When the limit member 42 is in the first position, the door arm 3, the elastic member 52 and the hinge body 511 cooperate to form a quadrilateral structure. When the limit member 42 is in the second position and the door arm 3 moves to the maximum stroke, the elastic member 52 and the hinge body 511 cooperate to form a triangular structure.
[0057] The elastic member 52 may be a spring or other elastic structures, and is not limited to this embodiment.
[0058] Furthermore, an annular groove is provided on the guide wheel 53, and the bottom of the door arm 3 is slidably clamped in the annular groove. The annular groove plays a positioning and guiding role in the sliding of the door arm 3, so that the door arm 3 is not easy to separate from the guide wheel 53, and the stability and reliability of the sliding of the door arm 3 are enhanced.
[0059] As for the specific structure of the door arm 3, in this embodiment, Figure 1 , Figure 3 and Figure 5 As shown, the door arm 3 includes an arm portion 31 and a hook portion 32, wherein the arm portion 31 and the guide wheel 53 are slidably matched, the end of the arm portion 31 away from the box door 2 is connected to the elastic member 52, the hook portion 32 is connected to the end of the arm portion 31 close to the box door 2, and the hook portion 32 is connected to the box door 2.
[0060] The hook portion 32 of the door arm 3 is connected to the box door 2, and the arm portion 31 of the door arm 3 and the guide wheel 53 are slidably matched. In the process of the box door 2 driving the door arm 3 to slide, the arm portion 31 is driven to slide relative to the guide wheel 53 through the hook portion 32, and the guide wheel 53 rotates under the sliding friction force. At the same time, the arm portion 31 drives the elastic member 52 to stretch or the elastic member 52 generates traction on the arm portion 31 through elastic force, so that the arm portion 31 slides and returns to its original position.
[0061] Furthermore, the door arm 3 also includes a blocking portion 33 disposed at one end of the arm portion 31 away from the door 2 and extending upward along the arm portion 31. The blocking portion 33 can abut against the side of the hinge seat 51 close to the door 2 or the side of the box body 1 close to the door 2 to limit the maximum travel of the door arm 3. In the process of the door 2 rotating and opening to drive the door arm 3 to slide, the blocking portion 33 follows the arm portion 31 to slide toward the door 2. When the blocking portion 33 abuts against the side of the hinge seat 51 close to the door 2 or the side of the box body 1 close to the door 2, the door arm 3 cannot continue to slide, and the door 2 rotates to the maximum angle at this time. Therefore, the maximum travel of the door arm 3 is limited by setting the blocking portion 33, and then the maximum opening angle of the door 2 is limited, so that it opens and closes within a reasonable range to avoid occupying too much space.
[0062] For example, the blocking portion 33 may be a flat plate extending upwardly from the arm portion 31, and a contact plate is provided on the side of the hinge seat 51 close to the door 2, and when the flat plate and the contact plate are in contact, the sliding of the door arm 3 is limited. Of course, in other embodiments, the sliding of the door arm 3 may also be limited by the contact between the blocking portion 33 and the inner wall of the box body 1 close to the door 2.
[0063] like Figure 2 and Figure 4As shown, with regard to the overall installation position of the door arm 3 and the hinge assembly 5, a mezzanine can be provided inside the box body 1, and the door arm 3 and the hinge assembly 5 are both provided in the mezzanine, and a portion of the door arm 3 extends out of the mezzanine to be connected to the external box door 2 to ensure the overall aesthetics.
[0064] In terms of the number of arrangements, in this embodiment, a set of door arms 3 and hinge assemblies 5 are arranged on both sides of the box body 1 to enable the box door 2 to rotate smoothly relative to the box body 1 .
[0065] In this embodiment, Figure 2 and Figure 3 As shown, when the limiting member 42 is in the first position, the limiting member 42 abuts against the blocking portion 33. The limiting member 42 abuts against the blocking portion 33, thereby limiting the movement of the blocking portion 33, thereby limiting the sliding of the door arm 3, so that the cabinet door 2 cannot be rotated and opened relative to the cabinet body 1, thereby ensuring the safety of the cooking device.
[0066] In terms of specific structural settings, in this embodiment, the driving member 41 can be an electromagnet, and the limiting member 42 can be a telescopic rod. The telescopic rod is movably connected to the electromagnet, and the electromagnet can drive the telescopic rod to switch between the first position and the second position. By powering on or off the electromagnet, the telescopic rod can be controlled to switch between the first position and the second position, so that the telescopic rod and the door arm 3 are abutted against the limit position or the telescopic rod and the door arm 3 are separated.
[0067] Specifically, the telescopic rod can be driven to move to the first position when the electromagnet is energized, and to the second position when the electromagnet is de-energized; or the telescopic rod can be driven to move to the first position when the electromagnet is de-energized, and to the second position when the electromagnet is energized.
[0068] Since the principle of the electromagnet driving the telescopic rod to move is a prior art, it will not be described in detail here.
[0069] As for the specific installation position, the limit assembly 4 can be arranged on the hinge assembly 5 or on the box body 1, and both can realize the installation of the limit assembly 4. In this embodiment, the electromagnet is fixed on the hinge body 511.
[0070] In addition, if Figure 1 , Figure 2 and Figure 4 As shown, the box body 1 further includes a front plate 12, which is arranged at the opening 11, and is provided with a through hole 121, through which the door arm 3 is connected to the box door 2. The front plate 12 can shield the interior of the interlayer to ensure the overall beauty of the cooking device, and the through hole 121 provided on the front plate 12 can facilitate the unimpeded sliding of the door arm 3.
[0071] Specifically, the size of the through hole 121 needs to be determined based on the maximum sliding stroke of the door arm 3 , so as not to affect the normal movement of the door arm 3 .
[0072] It is understandable that if Figures 6 to 8 As shown, in other embodiments, a slot or hole structure 311 may be provided on the door arm 3, and when the limiting member 42 is in the first position, the limiting member 42 is plugged into the slot or hole structure 311, and when the limiting member 42 is in the second position, the limiting member 42 is separated from the slot or hole structure 311. By providing the slot or hole structure 311 on the door arm 3, the limiting member 42 is plugged into the slot or hole structure 311 in the first position to limit the movement of the door arm 3, and at this time, the box door 2 cannot be rotated and opened relative to the box body 1, and the limiting member 42 is separated from the slot or hole structure 311 in the second position, thereby releasing the restriction on the door arm 3, and at this time, the box door 2 can be rotated and opened relative to the box body 1.
[0073] Specifically, the slot or hole structure 311 can be provided on the arm portion 31 of the door arm 3. For example, Figures 6 to 8 As shown, the arm portion 31 is provided with a through hole structure 311 .
[0074] In some embodiments, the door arm 3 as a whole can also be set as an L-shaped arm, the bottom of the L-shaped arm and the guide wheel 53 are slidably matched, and the top of the L-shaped arm is connected to the elastic member 52. At this time, the door arm 3 and the hinge seat 51 are matched at an angle.
[0075] To facilitate understanding of the cooking device of this embodiment, the use process is now introduced as follows:
[0076] When the cooking device needs to be opened, the driving member 41 drives the limiting member 42 to move from the first position to the second position, that is, the limiting member 42 and the blocking portion 33 are separated, or the limiting member 42 is separated from the groove body or the hole structure 311 to unlock the door arm 3. At this time, the door 2 is rotated to drive the arm portion 31 of the door arm 3 to slide relative to the guide wheel 53, and the elastic member 52 is stretched at the same time. When the blocking portion 33 and the side of the hinge seat 51 close to the door 2 or the side of the box 1 close to the door 2 abut, the door arm 3 slides to the maximum stroke and cannot slide further. At this time, the door 2 is rotated to open to the maximum angle, and the user can take in and put food through the opening 11 of the box 1.
[0077] On the contrary, when it is necessary to close the cooking equipment, rotating the door 2 in the opposite direction can drive the arm 31 of the door arm 3 to slide in the opposite direction relative to the guide wheel 53, thereby driving the blocking portion 33 and the side of the hinge seat 51 close to the door 2 or the side of the box body 1 close to the door 2 to separate. At the same time, the elastic force of the elastic member 52 pulls the arm 31 to achieve rapid sliding reset, assisting the door 2 to close quickly and saving effort in operation. After the door 2 is closed, the driving member 41 drives the limiting member 42 to move from the second position to the first position, that is, the limiting member 42 and the blocking portion 33 are abutted, or the limiting member 42 is inserted into the groove body or the hole structure 311 to lock the door arm 3. At this time, the door arm 3 cannot slide, thereby limiting the rotation of the door 2 relative to the box body 1. At this time, the cooking equipment cannot be opened by pulling the door 2 from the outside, which can effectively prevent children from accidentally touching and opening the door 2, thereby ensuring the safety of food cooking.
[0078] Of course, the above description is only the optimal technical solution of this embodiment. In addition:
[0079] In some embodiments, the driving member 41 can also be a linear drive form such as a linear cylinder or a motor plus a screw combination. By driving the limit member 42 to move linearly through the linear cylinder or the motor plus a screw, the limit member 42 can also be switched between the first position and the second position.
[0080] In some embodiments, the driving member 41 may also be a driving structure such as a rotary cylinder. By driving the limiting member 42 to rotate through the rotary cylinder, the limiting member 42 can also be switched between the first position and the second position.
[0081] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
