[0041] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] See also Figures 1 to 11 An electric oven comprises a shell 1 constituting a main structure, and also comprises an upper cooking cavity 2 located at the upper part of the shell 1; a lower cooking cavity 3 located at the lower part of the shell 1; an upper door 4 corresponding to the upper cooking cavity 2; a lower door 5 corresponding to the lower cooking cavity 3 and hinged to the shell 1 and the upper door 4 respectively, and realizing synchronous opening and closing under the drive of the upper door 4; an interlocking mechanism 6 for making the upper door 4 and the lower door 5 open and close synchronously when the upper door 4 is locked, and making the upper door 4 open and close independently when the lock is released.

[0043] The utility model provides an electric oven, which allows a user to perform two different cooking operations at the same time by arranging a separate upper cooking cavity 2 and a lower cooking cavity 3 in a housing 1, thereby improving cooking efficiency. An upper door 4 and a lower door 5 correspond to the upper 2 and lower cooking cavities 3, respectively. When the upper and lower cooking cavities need to be used at the same time, the upper door 4 and the lower door 5 are locked by an interlocking mechanism 6, so that the two can be opened and closed synchronously, thereby avoiding operational inconvenience. When only one of the cooking cavities needs to be used, the interlocking mechanism 6 is unlocked, and the user can choose to open and close the upper door 4 independently, thereby improving the flexibility of use.

[0044] Furthermore, as a preferred embodiment of the present scheme but not a limitation, a handle 7 is provided on the upper door 4, the interlocking mechanism 6 is installed on the upper door 4, and positioning columns 8 fixedly connected to the lower door 5 are respectively provided on both sides of the upper door 4, and the positioning columns 8 can cooperate with the interlocking mechanism 6 to perform horizontal locking, thereby realizing the synchronous opening and closing of the upper door 4 and the lower door 5.

[0045] In this embodiment, a handle 7 is provided on the upper door 4 for easy gripping and operation by the user. An interlocking mechanism 6 is installed on the upper door 4 and can cooperate with the positioning column 8 through a specific mechanical structure design.

[0046] Specifically, the positioning posts 8 on both sides of the upper door 4 are fixedly connected to the lower door 5. When the upper door 4 and the lower door 5 need to be opened and closed synchronously, the interlocking mechanism 6 and the positioning posts 8 are locked in the horizontal direction, thereby improving the efficiency. In this way, when the user opens or closes the upper door 4 through the handle 7, the lower door 5 will also be opened or closed synchronously due to the action of the interlocking mechanism 6.

[0047] When the synchronous switch function is not needed, the interlocking mechanism 6 can release the lock on the positioning column 8, so that the upper door 4 can be opened and closed independently of the lower door 5.

[0048] Furthermore, as a preferred embodiment of the present scheme but not a limitation, the interlocking mechanism 6 includes a guide base 61, which is fixedly connected to the inner side of the upper box door 4, and is provided with a guide channel 62 inside, with limit plates 63 at both ends; a locking member 64, one end of which is passed through the guide channel 62 and can move laterally along the length direction of the guide base 61, and the other end can be connected to the positioning column 8 to lock the upper box door 4 and the lower box door 5 to achieve common opening and closing; a power device 65, which is provided on the handle 7 and is used to drive the locking member 64 to move laterally.

[0049] In this embodiment, the interlocking mechanism 6 is composed of a guide base 61, a locking member 64 and a power device 65. The guide base 61 is fixed to the inner side of the upper door 4, and a guide channel 62 is provided inside the guide base 61. Limiting plates 63 are provided at both ends of the channel to limit the movement range of the locking member 64.

[0050] One end of the locking member 64 passes through the guide channel 62 and can move laterally in the length direction of the guide base 61. The other end of the locking member 64 can be connected to the positioning column 8, thereby locking the upper door 4 and the lower door 5 so that the two can be opened and closed synchronously.

[0051] The power device 65 is arranged on the handle 7. The user operates the handle 7 to drive the locking member 64 to move laterally in the guide channel 62. When the user needs to open and close the upper door 4 and the lower door 5 synchronously, the user operates the handle 7 to connect the locking member 64 with the positioning column 8 to achieve locking; when the user needs to open and close the upper door 4 independently, the user operates the handle 7 again to separate the locking member 64 from the positioning column 8 to release the lock. The design of the interlocking mechanism 6 is integrated on the upper door 4 and the handle 7, and the structure is compact and does not occupy additional space.

[0052] Further, as a preferred implementation of the present solution but not a limitation, there are two locking members 64 which are arranged opposite to each other up and down, and one end of the locking member 64 passing through the guide channel 62 can respectively abut against the limiting plate 63.

[0053] In this embodiment, in order to enhance the locking effect between the upper door 4 and the lower door 5, a structure in which two locking members 64 are arranged opposite to each other is adopted. This design can provide better stability and reliability, ensuring that the upper door 4 and the lower door 5 can be firmly locked during the synchronous opening and closing process.

[0054] Two locking members 64 are respectively arranged in the guide channel 62, and one end of them can abut against the limit plate 63. In this way, when the locking member 64 moves laterally in the guide channel 62, the limit plate 63 can limit its range of motion to prevent the locking member 64 from excessively moving and causing failure.

[0055] When it is necessary to realize synchronous opening and closing of the upper door 4 and the lower door 5, the two locking members 64 are driven to move inward or outward at the same time by operating the power device 65 on the handle 7, so that they are connected or separated from the positioning column 8, thereby realizing the locking or unlocking function.

[0056] Further, as a preferred embodiment of the present invention but not a limitation, the locking member 64 includes a locking end 641 which is connected to the corresponding access port on the positioning column 8, the locking end 641 is connected to an extension section 642, and the extension section 642 is provided with a transition slope at the connected position along the direction of the locking end 641 so that the cross-sectional area of ​​the extension section 642 is larger than the cross-sectional area of ​​the locking end 641, the extension section 642 is connected to a limiting portion 643 which is provided in the guide base and can cooperate and abut against the limiting plate 63, and the limiting portion 643 is connected to a power receiving portion 644 which is connected to the power device 65.

[0057] In this embodiment, the locking member 64 is composed of multiple parts to achieve its multiple functions in the interlocking mechanism.

[0058] The locking end 641 is the part that connects the locking member 64 and the positioning column 8, and is matched with the access port on the positioning column 8 to achieve the locking of the upper door 4 and the lower door 5. The extension section 642 is connected behind the locking end 641, and its cross-sectional area is larger than the cross-sectional area of ​​the locking end 641. Such a design can provide better connection strength and stability, and also limit the range of movable connection between the locking end and the positioning column 8. The transition slope on the extension section 642 can facilitate the locking end 641 to more smoothly lock and match with the corresponding receiving hole on the positioning column 8.

[0059] The limiting portion 643 is located in the guide base and abuts against the limiting plate 63 to limit the lateral movement range of the locking member 64 to prevent it from excessive movement. The power receiving portion 644 is connected to the power device 65 provided on the handle 7. When the user operates the handle 7, the power device 65 drives the locking member 64 to move lateraly through the power receiving portion 644, thereby realizing the locking or unlocking function.

[0060] Furthermore, as a preferred embodiment of the present invention but not a limitation, the power device 65 includes a starting shaft 651 which is arranged in the handle 7 and one end of which passes through the upper box door 4 and enters the guide base 61; the starting shaft 651 is located in the guide base 61 and has a power input part 652 on one end thereof which is connected to the power receiving part 644.

[0061] In this embodiment, the power device 65 drives the locking member 64 by designing the starting shaft 651 and the power input portion 652 .

[0062] The start shaft 651 is arranged inside the handle 7, and one end thereof passes through the upper door 4 and extends to the inside of the guide base 61. Such an arrangement enables the start shaft 651 to transmit the user's operating force on the handle 7 to the locking member 64 in the guide base 61.

[0063] The power input part 652 is arranged on one end of the start shaft 651 located in the guide base 61, and the power input part 652 is connected with the power receiving part 644 on the locking member 64. When the user operates the handle 7, the start shaft 651 will rotate or move accordingly, and the power will be transmitted to the power receiving part 644 through the power input part 652, thereby driving the locking member 64 to move horizontally in the guide channel 62, so as to achieve the locking or unlocking of the upper door 4 and the lower door 5.

[0064] Furthermore, as a preferred embodiment of the present scheme but not a limitation, the handle 7 is a handle-type structure with a hollow interior, including a hollow tubular handle composed of a U-shaped handle inner frame 71 and a handle outer frame 72 spliced ​​and fixed thereto, which may be a round tube or a square tube. In the present scheme, a square tubular handle with a rounded cross-section is preferably used, both ends of the handle 7 are provided with connecting seats 73 fixed to the upper box door 4, the middle portion of the handle 7 is provided with a mounting tube 74 that accommodates the start shaft 651 and is connected to the upper box door 4, the start shaft 651 passes through the handle 7 along the mounting tube 74 and is fixedly connected to a control button 75 that can drive it to rotate, the outer periphery of the control button 75 is provided with anti-slip patterns, the mounting tube 74 is provided with a guide groove 76 adapted to the start shaft 651, the guide groove 76 is provided with a structural plate 77 fixedly connected to the inner cavity wall of the mounting tube 74, and the structural plates 77 are evenly arranged along the inner cavity wall of the mounting tube 74.

[0065] In this embodiment, the handle 7 adopts a handle structure with a hollow interior, and is a square tubular handle with rounded corners formed by splicing and fixing an inner handle frame 71 and an outer handle frame 72. This structure provides sufficient strength and rigidity, reduces the weight of the handle 7, and has a beautiful appearance.

[0066] The two ends of the handle 7 are fixedly connected to the upper box door 4 through the connecting seat 73, ensuring the reliability of the connection between the handle 7 and the upper box door 4. A mounting tube 74 is provided in the middle of the handle 7 for accommodating the starting shaft 651 and realizing the connection between the starting shaft 651 and the upper box door 4.

[0067] The start shaft 651 passes through the handle 7 along the mounting tube 74, and is fixedly connected to the handle 7. The outer periphery of the control button 75 is provided with anti-skid patterns, which is convenient for the user to operate and increases the friction during operation to prevent slipping. When the user turns the control button 75, the start shaft 651 can be driven to rotate, thereby driving the locking member 64 to move through the power input part 652.

[0068] A guide groove 76 is provided in the mounting tube 74, which is adapted to the shape of the start shaft 651 and can guide the movement of the start shaft 651 to prevent it from deflecting during the movement. Four structural plates 77 are provided around the outer periphery of the guide groove 76, and the four structural plates 77 are fixedly connected to the inner cavity walls of the four surfaces of the mounting tube 74 at the same time, so that the structural plates are perpendicular to each other, thereby increasing the strength and rigidity of the mounting tube 74.

[0069] Furthermore, as a preferred embodiment of the present scheme but not a limitation, the upper box door 4 includes an outer door frame 41 and an inner door frame 42 assembled and fixed thereto, the handle 7 is installed on the outer side of the outer door frame 41, the guide base 61 is fixedly connected to the inner side of the outer door frame 41, and both sides of the inner door frame 42 are respectively provided with engaging grooves 43 which can be engaged and overlapped with the positioning column 8, and the outer side walls of the two engaging grooves 43 are respectively connected with limiting members 44 for the locking end 641 to pass through and connect with the positioning column 8.

[0070] In this embodiment, the upper door 4 is assembled and fixed by an outer door frame 41 and an inner door frame 42. A handle 7 is installed on the outer side of the outer door frame 41 to facilitate the user to open and close the upper door 4. A guide base 61 is fixedly connected to the inner side of the outer door frame 41 to provide guidance and support for the movement of the locking member 64.

[0071] Both sides of the inner door frame 42 are provided with engaging grooves 43 for engaging and overlapping with the positioning posts 8 on the lower door 5. When the upper door 4 and the lower door 5 are closed, the positioning posts 8 are inserted into the engaging grooves 43 to achieve the connection between the two doors.

[0072] A limiting member 44 is connected to the outer side wall of the engaging groove 43, and the position of the limiting member 44 corresponds to the locking end 641 of the locking member 64. When the upper door 4 and the lower door 5 need to be locked, the locking end 641 of the locking member 64 passes through the limiting member 44 and is connected to the positioning column 8, thereby locking the two doors together to achieve synchronous opening and closing.

[0073] Furthermore, as a preferred embodiment of the present invention but not a limitation, the bottom sides of the upper door 4 are hinged to the top sides of the lower door 5, and when the locking piece 64 is not connected with the positioning column 8, the upper door 4 can be flipped downward to be perpendicular to the lower door 5.

[0074] In this embodiment, the upper door 4 and the lower door 5 are connected together by hinges. Specifically, the bottom sides of the upper door 4 and the top sides of the lower door 5 are connected by hinges, so that the upper door 4 can rotate relative to the lower door 5 around the hinge axis.

[0075] When the locking member 64 is not connected with the positioning column 8, that is, the upper door 4 and the lower door 5 are in an unlocked state, the upper door 4 can be flipped downward to a position perpendicular to the lower door 5. This design allows the upper door 4 to be flipped to a vertical position when the lower cooking chamber 2 is not needed, thereby saving space and providing greater operational convenience.

[0076] When the upper cooking cavity 2 and the lower cooking cavity 3 need to be used simultaneously, the interlocking mechanism 6 can be operated to make the locking member 64 cooperate with the positioning column 8 to lock the upper door 4 and the lower door 5 together to achieve synchronous opening and closing.

[0077] Further, as a preferred embodiment of the present invention but not a limitation, the power input part 652 is a moving gear, the power receiving part 644 is a rack, and the racks of the two locking members 64 are respectively meshed with the upper and lower ends of the moving gear, so that the two oppositely arranged locking members 64 move in opposite directions when the moving gear cooperates with the rack.

[0078] In this embodiment, the power input part 652 adopts a dynamic gear structure, and the power receiving part 644 adopts a rack structure. This gear and rack transmission method can effectively convert rotational motion into linear motion.

[0079] Specifically, the movable gear is arranged on one end of the start shaft 651 located in the guide base 61, and racks are respectively arranged on two oppositely arranged locking members 64. When the movable gear is engaged with the racks, the user rotates the start shaft 651 by operating the control button 75, thereby driving the movable gear to rotate.

[0080] Since the racks on the two locking members 64 are respectively meshed with the upper and lower ends of the moving gear, and they are arranged in opposite directions, when the moving gear rotates, the two locking members 64 will perform linear motion in opposite directions. That is, when one locking member 64 moves to the left, the other locking member 64 will move to the right, and vice versa.

[0081] This movement in opposite directions enables the two locking members 64 to be connected to or separated from the positioning column 8 at the same time, thereby achieving synchronous locking or unlocking of the upper door 4 and the lower door 5 .

[0082] The working principle of this embodiment is as follows:

[0083] When the user needs to use the upper cooking cavity 2 and the lower cooking cavity 3 at the same time or needs to use the lower cooking cavity 3, the user rotates the start shaft 651 by operating the control button 75 to drive the movable gear to rotate. The rotation of the movable gear drives the two locking members 64 to perform linear motion in opposite directions through meshing with the rack, so that the locking end 641 is connected to the positioning column 8, thereby locking the upper door 4 and the lower door 5 together. At this time, the upper door 4 and the lower door 5 can be opened and closed synchronously.

[0084] When only the upper cooking cavity 2 is needed, the user operates the control button 75 again to separate the locking end 641 of the locking member 64 from the positioning column 8 to release the lock. At this time, the upper door 4 can be opened and closed independently and can be flipped downward to a position perpendicular to the lower door 5.

[0085] The above are implementation methods provided in combination with specific contents, and it is not intended that the specific implementation of this application is limited to these descriptions. Any method structure similar to the present application, or some technical deductions or replacements made based on the concept of the present application, shall be deemed to be within the protection scope of this application.
