The only feature is that the lower door 5 can be hinged to the shell 1, and the hinged part can be the bottom of the two or the left and right sides; the entire cooking area is divided into an upper cooking cavity 2 and a lower cooking cavity 3. This design not only optimizes space utilization, but also provides users with an environment for cooking different foods at the same time, increasing the diversity and efficiency of cooking. In addition, when the upper cooking cavity 2 is used alone, there is no need to open and close the lower door 5, and when the lower cooking cavity 3 is used, the interlocking mechanism 6 can ensure that the lower door 5 and the upper door 4 are opened and closed synchronously, avoiding safety risks caused by user misoperation, while also simplifying the operating steps and improving the user experience.

[0051] Preferably, if Figures 3 to 5 As shown, the upper door 4 is provided with a handle 7 to provide the user with a more comfortable holding and operating experience, which is convenient for the user to easily open and close the upper door 4, thereby improving the comfort and safety of operation. The inner side of the upper door 4 is provided with a mounting groove corresponding to the interlocking mechanism 6, which provides a stable installation position for the interlocking mechanism 6, ensuring that the connection between the interlocking mechanism 6 and the upper door 4 is firm and reliable, thereby improving the overall safety of the door system, and will not affect the external appearance or increase the complexity of the appearance design. 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 lock in the horizontal direction, and the interlocking mechanism 6 can cooperate with the lower door 5 to lock in the vertical direction, thereby realizing the synchronous opening and closing of the upper door 4 and the lower door 5.

[0053] Preferably, if Figures 5 to 7 As shown, there are two horizontal locking members 61 which are stacked up and down and arranged opposite to each other. The horizontal locking members 61 cooperate with the power assembly 9 to perform horizontal movements in relative directions along their respective mounting grooves and then are respectively connected to the interfaces on the positioning columns 8, thereby realizing double locking of the oven door in the horizontal direction and making the oven door more secure when closed and less prone to accidental opening and closing due to external factors, thereby improving the safety of the electric oven. On the other hand, the power assembly 9 is arranged on the handle 7, so that the user only needs to operate the corresponding components on the handle 7 to lock and unlock the two oven doors, thereby improving the convenience and practicality of operation; the two horizontal locking members 61 respectively cause the vertical locking member 62 to generate vertical movement through the corresponding linkage members 63.

[0054] Preferably, if Figure 5-8As shown, the horizontal locking piece 61 includes a locking end 611 that is connected to the corresponding access port on the positioning column 8. The locking end 611 of the horizontal locking piece 61 is designed to have a shape that matches the interface on the positioning column 8, and can be cylindrical, conical, wedge-shaped, etc., to ensure the accurate positioning and locking of the upper and lower doors in the horizontal direction. The locking end 611 is connected to an extension section 612. The extension section 612 has a transition slope at the connected position along the direction of the locking end 611 so that the cross-sectional area of ​​the extension section 612 is larger than the cross-sectional area of ​​the locking end 611, which is used to optimize the force distribution of the horizontal locking piece 61 during movement, reduce friction, and increase the strength and stability of the structure. The extension section 612 is provided with a first connecting rod on one side close to the locking end 611. The connecting portion 613 is connected to the upper end of the linkage member 63, and the extension section 612 is connected to a power receiving portion 614 that cooperates with the power assembly 9 in the direction close to the handle 7. As a preferred scheme, a trapezoidal groove is provided on the power receiving portion 614 pointing to the side of the power assembly 9, so that the power assembly 9 can quickly and accurately cooperate with the horizontal locking member 61 and transmit power to prompt the horizontal locking member 61 to move laterally along the installation groove. Another optional scheme is to set a rack structure on the power receiving portion 614 to form a gear connection with the corresponding power assembly 9, and a spring groove 615 is provided at one end along the length direction of the power receiving portion 614 for installing the corresponding first reset spring 616 to ensure that the horizontal locking member 61 can be quickly reset after being unlocked.

[0055] Preferably, if Figure 5-7 As shown, the vertical locking member 62 includes a locking rod 621 inserted into the corresponding receiving hole on the lower door 5, realizing the physical connection between the upper door 4 and the lower door 5, thereby ensuring the stability of the door in the closed state. The upper end of the locking rod 621 is provided with a limiting end 622 with a cross-sectional area larger than that of the locking rod 621. The limiting end 622 cooperates with the corresponding mounting groove in the upper door 4 to limit the vertical movement range of the vertical locking member 62 to prevent excessive movement, thereby ensuring the stability and safety of the door when opening and closing. The limiting end 622 is provided with a second connecting portion 623 that cooperates with the lower end of the linkage member 63, thereby ensuring the synchronous adjustment of the horizontal locking member 61 and the vertical locking member 62, and maintaining the continuity and accuracy of the operation.

[0056] Preferably, if Figure 5 , Figure 7As shown, the middle part of the linkage 63 is hinged to the inner side of the upper door 4, so that the linkage 63 can rotate around the hinge point, thereby transmitting power in the horizontal and vertical directions to realize the interlocking control of the upper and lower doors. The upper part of the linkage 63 is hinged with the first connection part 613, and the lower part of the linkage 63 is provided with a strip hinge hole 631 which matches the cross-sectional shape of the second connection part 623 and is inclined toward the power receiving part 614, so that when the linkage 63 rotates, the second connection part 623 cooperates with the strip hinge hole 631 to perform relative movement. It should be emphasized that when the linkage 63 rotates, the cooperation between the second connection part 623 and the strip hinge hole 631 is not just a simple linear sliding, but through the inclined design of the strip hinge hole 631, the second connection part 623 is guided to move along a specific path, which is the key to the vertical movement of the vertical locking member 62, and can also control the vertical locking member 62 more accurately and smoothly.

[0057] Preferably, a guide base 10 for guiding and resetting the horizontal locking member 61 is installed on the inner side of the upper door 4. The guide base 10, as an independent motion control device, ensures that the horizontal locking member 61 follows a predetermined path during movement, thereby avoiding the offset or jamming of the locking member during movement, and improving the stability and fluency of operation. The guide base 10 includes a corresponding first guide groove 101 sleeved with the power receiving part 614. The first guide groove 101 provides an accurate moving path for the power receiving part 614 of the horizontal locking member 61, thereby ensuring the accuracy of the locking member during locking and unlocking. The first limiting parts 102 that can abut against the first reset spring 616 are respectively provided at both ends of the guide base 10 along the direction of the first guide groove 101. The cooperation between the first limiting part 102 and the first reset spring 616 ensures that the horizontal locking member 61 can be quickly and accurately reset after operation. This design avoids the safety hazard or inconvenience caused by incomplete or inadequate reset of the locking member, and further improves the performance and safety of the electric oven.

The vertical design of the embedding piece 91 ensures its stable connection with the guide base 10, thereby enhancing the stability of the entire power transmission system. At the same time, the plug-in structure of the upper embedding part 911 and the lower embedding part 912 further ensures the stability of the connection. A connecting rod 913 located in the guide base 10 is provided between the upper embedding part 911 and the lower embedding part 912. The connecting rod 913 abuts against the inclined surface on the trapezoidal groove of the power receiving part 614 to enable the power receiving part 614 to move laterally in a direction perpendicular to the connecting rod 913. The design of the connecting rod 913 and the inclined surface of the trapezoidal groove cleverly pushes The force is converted into horizontal movement, thereby realizing effective control of the horizontal locking piece 61. A second return spring 914 is fixedly provided between the connecting rod 913 and the inner wall of the guide base 10. The setting of the second return spring 914 ensures that the insert 91 can be quickly reset after the pressure of the power rod 92 is removed, so that the horizontal locking piece 61 and the vertical locking piece 62 return to the initial position to complete the interlocking of the upper and lower doors, thereby enhancing the reliability of the interlocking mechanism 6 and avoiding the safety hazard caused by incomplete resetting of the locking piece; the insert 91 is abutted against a power rod 92 perpendicular to it, and the power rod 92 is inserted into the handle 7. The power rod 92 is provided with a limit rod 921 that can be engaged with the handle 7 at one end of the power rod 92 close to the insert 91, thereby ensuring the stability of the power rod 92 during operation and preventing misoperation caused by shaking.

[0059] Preferably, if Figure 10-14As shown, the handle 7 includes a mounting seat 71 fixedly connected to the guide base 10, which ensures the stable connection between the handle 7 and the main body of the electric oven and provides a stable support base for the handle 7. And a connecting pipe 72 is arranged away from the mounting seat 71, and the lower end of the connecting pipe 72 is connected to a handle 73.

The power rod 92 passes through the first mounting cavity 74 and is also provided with a second mounting cavity 75. The tail end of the power rod 92 passes through the second mounting cavity 75 and is fixedly connected to a corresponding control button 922 that can rotate along the inner wall of the second mounting cavity 75. The user can drive the power rod 92 to move by pressing the control button 922, thereby controlling the locking state of the upper and lower doors, and then rotate the control button 922 to make the limit rod 921 It is engaged with the first mounting cavity 74 to maintain the interlocking or non-interlocking state of the upper and lower doors. A corresponding third return spring 923 is sleeved on the power rod 92, and the third return spring 923 abuts against the control button 922 and the cavity wall of the second mounting cavity 75 respectively, ensuring that the control button 922 can automatically return to the preset position when not subjected to external force. The outer periphery of the control button 922 away from the end of the second mounting cavity 75 is sleeved with a textured pressure cover 924 that can abut against the edge of the end of the connecting tube 72. The textured pressure cover 924 enhances the friction during finger operation, so that the user can operate normally even with wet or slippery hands.

[0060] Preferably, if Figure 12-14 As shown, a connecting hole 76 is provided between the first installation cavity 74 and the second installation cavity 75 for the power rod 92 to pass through. A pair of first limiting plates 77 adapted to the limiting rod 921 are symmetrically provided around the connecting hole 76 at one end of the first installation cavity 74 to stabilize the position of the power rod 92 in the first installation cavity. It should be emphasized that when the limiting rod 921 is engaged with the first limiting plates 77, the upper and lower doors are in the following state. Figure 4 The interlocking state shown will synchronize the switches.

[0061] Preferably, if Figure 12-14 As shown, the upper ends of the two first limit plates 77 are respectively provided with a second limit plate 78 which is perpendicular thereto and connected to the inner wall of the first mounting cavity 74. The two second limit plates 78 are parallel to each other and the parallel spacing matches the rod diameter of the power rod 92, so that when the power rod 92 moves toward the upper door 4 to the upper end of the first limit plate 77, the control button 922 can be rotated to make the limit rod 921 engage with the second limit plate 78. At this time, the upper and lower doors are in a state as shown in FIG. Figure 3 In the non-interlocked state shown, the upper door can be opened and closed independently.

[0062] Preferably, if Fig.12 , Fig.15 As shown, a second guide groove 79 matching the power rod 92 is provided around the connecting hole 76 at one end of the second installation cavity 75, ensuring that the power rod 92 can move along a predetermined track to prevent it from deflecting or getting stuck.

[0063] Preferably, if Fig.14 As shown, the first limit plate 77 is an arc-shaped limit plate adapted to the shape of the power rod 92. The limit plate 77 with an arc-shaped design can better fit the surface of the power rod 92 and reduce the gap, thereby providing more stable support when the power rod 92 moves to prevent shaking or deviation. This design also helps to evenly distribute contact pressure, reduce local wear, and extend component life. At the same time, the arc-shaped design can also reduce noise to a certain extent, because the closer contact reduces unnecessary collision sounds between components. Furthermore, the user can feel smoother and more precise feedback when turning the control knob 922, which enhances the controllability and comfort of the operation.

[0064] Embodiment 2: This embodiment is different from Embodiment 1 in that the structures of some components of the interlocking mechanism 6 are different.

The significance of arranging the same first rack 617 on the upper and lower sides is to improve the versatility of the horizontal locking member 61. Under this design, the locking function can be achieved whether it is arranged on the left or right side of the box door. The linkage member 63 in this embodiment is a transmission gear set hinged in the upper box door including a main gear 632 and a sub-gear 633. The upper end of the main gear 632 is meshed with the first rack 617, and the upper end of the limiting end 622 of the vertical locking member 62 is vertically provided with a second rack 624 that meshes with the inward side of the sub-gear 633, so that when the horizontal locking member 61 moves toward the positioning column 8 for locking, the vertical locking member 62 moves downward under the transmission cooperation of the main gear 632 and the sub-gear 633 to lock with the corresponding receiving hole of the lower box door 5, and finally completes the interlocking of the upper and lower box doors. The other structures are the same as those in Example 1. In summary, the electric oven proposed in this embodiment improves the accuracy and efficiency of the interlocking mechanism 6 in unlocking and locking the upper and lower doors on the basis of Embodiment 1, and can ensure the accuracy and reliability of locking and unlocking.

[0065] Principle of the utility model:

[0066] The utility model proposes a double cooking chamber electric oven with upper and lower double doors. The upper door can be opened and closed independently, and the lower door is locked with the upper door through an interlocking mechanism to be opened and closed synchronously. Specifically, when the user only uses the upper cooking chamber, the power rod can be pushed by pressing the control button on the handle, and the embedded part moves toward the direction of the electric oven under the pressure of the power rod. The connecting rod provided on the embedded part abuts against the inclined surface on the trapezoidal groove of the power receiving part, so that the two horizontal locking parts move horizontally toward the middle. At the same time, the vertical locking parts on both sides move vertically synchronously under the action of the linkage part, and finally the horizontal locking part is unlocked from the positioning column, the vertical locking part and the lower door are unlocked, and the upper door and the lower door are completely unlocked from the interlocking state. At this time, by rotating the control button, the limit rod provided on the power rod is engaged with the second limit plate to maintain the non-interlocking state, and the upper door can be opened and closed independently. When the user needs to use the lower cooking chamber, the control knob is rotated to the initial position, the power rod rebounds under the action of the third reset spring, the limit rod is finally connected with the first limit plate, and then the two horizontal locking parts move to both sides and lock with the positioning column under the action of the first reset spring, and the vertical locking parts are locked downward with the lower door under the action of the linkage part, and the upper and lower doors are interlocked. At this time, the upper and lower doors can be opened and closed at the same time by just using the handle of the upper door. This electric oven fully considers the user's operating convenience and safety, and ensures the synchronization and accuracy of the operation through the design of the interlocking mechanism, thereby improving the cooking efficiency and user experience.
