[0002] The utility model relates to the technical field of electric oven door handles, in particular to a box door handle structure of an electric oven. [Background technology]

[0004] With the diversification of people's cooking needs and the pursuit of quality of life, multi-cooking chamber electric ovens have gradually entered the market. This type of electric oven usually has two or more independent doors, each door corresponds to an independent cooking chamber, and can perform different cooking tasks at the same time, which improves cooking efficiency and flexibility. In the structure of the electric oven, the door handle is one of the important components. With the emergence of multi-cooking chamber electric ovens, the door handles also need to be designed in a corresponding supporting manner. On the market, double-cooking chamber electric ovens mainly operate the corresponding doors by installing two independent handles. This design scheme requires users to frequently open and close the doors in certain scenarios, such as when cooking multiple portions of food, which is inconvenient to operate. In addition, installing multiple handles will inevitably take up more space and increase costs. Therefore, for a double-cooking chamber electric oven, it is necessary to design a handle structure that improves user experience and reduces the steps of door opening and closing operations. [Contents of the utility model]

[0035] Specific embodiments, such as Figure 1-8 The door handle structure of an electric oven shown in the figure comprises a handle body 2 connected to a door body 1 having a double door structure, wherein an interlocking start mechanism 4 is arranged in the handle body 2 and cooperates with a corresponding interlocking mechanism on the door to cause the two doors to be locked and opened synchronously, see Figure 3-4 By arranging an interlock starting mechanism 4 in the handle body 2, it can cooperate with the corresponding interlock mechanism on the oven door, so that the two oven doors can be locked and opened and closed synchronously, thereby improving the operating convenience of the electric oven, allowing the user to open and close the two oven doors at the same time or separately open and close the oven door on which the handle body 2 is installed, without having to open and close the oven doors through handles separately arranged on each independent oven door as in the oven door structure under the prior art, thereby greatly reducing the cumbersomeness and inconvenience of operation. In addition, by integrating the interlock starting mechanism 4 inside the handle body 2, the external structure is made simpler and smoother, saving external space, and maintaining the beauty of the overall structure and the compactness of the design.

[0036] Furthermore, if Figure 1-4 As shown, the handle body 2 includes a mounting seat 21 fixedly connected to the door body 1 , the mounting seat 21 is connected to a mounting tube 22 with the interlocking starting mechanism 4 built in, and the lower end of the mounting tube 22 is connected to a handle 23 .

[0037] For further information, see Figure 3 A first mounting cavity 24 for mounting the interlocking starting mechanism 4 is provided on one side of the mounting tube 22 near the mounting seat 21. The first mounting cavity 24 is connected to a second mounting cavity 25 for mounting the interlocking starting mechanism 4. The double-cavity structure effectively utilizes the limited space inside the handle body 2, provides a precise mounting position for the interlocking starting mechanism 4, and enables the interlocking starting mechanism 4 and its related components to be compactly integrated. Furthermore, since the interlocking starting mechanism 4 is completely encapsulated in the cavity of the mounting tube 22, it is effectively isolated from the influence of external environmental factors such as dust and water vapor, reduces the possibility of wear and corrosion, and thus extends the service life of the interlocking starting mechanism 4.

[0038] Furthermore, if Figure 3 , 4As shown in Figure 8, the interlock starting mechanism 4 includes a starting shaft 41 which is inserted into the first mounting cavity 24 and the second mounting cavity 25 and is used to provide a driving force for the corresponding interlocking mechanism on the door. A limiting rod 42 which can be engaged with the first mounting cavity 24 is provided on one end of the starting shaft 41 close to the mounting seat 21. The setting of the limiting rod 42 ensures the stability of the starting shaft 41 during operation. When the end of the starting shaft 41 close to the mounting seat 21 is engaged with the first mounting cavity 24, the starting shaft 41 can be effectively prevented from accidentally moving or rotating. The other end of the starting shaft 41 is fixedly connected to a control button 43 which can drive it to move linearly or rotate in the mounting tube 22. The user can conveniently start or close the interlocking mechanism on the door by operating the control button 43, which simplifies the operating steps and improves the user experience.

[0039] Specifically, Figure 4 As shown, the control button 43 includes an access end 431 with a shape matching one end extending into the second mounting cavity 25, and the other end of the control button 43 is provided with an operating end 432 connected to the access end 431 and enabling linear movement or rotation along the inner wall of the second mounting cavity 25, thereby ensuring a close fit between the control button 43 and the second mounting cavity 25, reducing gaps and friction during movement, improving power transmission efficiency and accuracy during operation, and making the starting shaft 41 smoother and more reliable when driving the two doors to lock or unlock.

[0040] Furthermore, if Figure 4 As shown, the end sleeve of the operating end 432 is provided with a textured pressure cover 433 that can abut against the end wall of the mounting tube 22. The texture design increases the friction between the fingers and the operating end, and provides a good grip even when the hands are wet or oily, ensuring that the user can operate stably and accurately, and improving the comfort and safety of operation.

[0041] Furthermore, if Figure 3-4 As shown, the starting shaft 41 is sleeved with a corresponding reset spring 44, and the reset spring 44 abuts against the control button 43 and the wall of the second mounting cavity 25 respectively. The reset spring 44 provides an automatic reset function for the interlocking starting mechanism 4. When the user operates the control button 43 to release the engagement state of the limit rod 42 and the first mounting cavity 24, the reset spring 44 drives the starting shaft 41 and the control button 43 back to the initial position, so that the user does not need to pay extra attention to the reset problem when operating the box door handle, thereby improving the convenience and efficiency of operation.

[0042] Furthermore, if Figure 3 , Figure 5As shown, a connecting hole 26 for the starting shaft 41 to penetrate is provided between the first mounting cavity 24 and the second mounting cavity 25, and a pair of first limiting plates 27 adapted to the limiting rod 42 are symmetrically provided around the connecting hole 26 at one end in the first mounting cavity 24, and the upper ends of the two first limiting plates 27 are respectively provided with a second limiting plate 28 perpendicular thereto and connected to the inner wall of the first mounting cavity 24, and the first limiting plate 27 is an arc-shaped limiting plate adapted to the shape of the starting shaft 41, and the first limiting plate 27 and the second limiting plate 28 are used to limit or guide the movement of the starting shaft 41 and the limiting rod 42, and the two second limiting plates 28 are parallel to each other and the parallel spacing matches the shaft diameter of the starting shaft 41, so that when the limiting rod 42 on the starting shaft 41 moves toward the box door direction to the upper end of the first limiting plate 27, the control button 43 can be rotated to allow the limiting rod 42 to be aligned with the second limiting plate 28 abuts against. Specifically, in this embodiment, when the limit rod 42 is engaged with the first limit plate 27, the entire interlock starting mechanism 4 is in an initial state. When the control button 43 is pressed, the starting shaft 41 moves toward the outside of the mounting cavity, and the return spring 44 is compressed accordingly. The limit rod 42 also begins to disengage from the first limit plate 27 until the pressure cover 433 at the end of the control button 43 abuts against the tube wall at the end of the mounting tube 22, and the return spring 44 reaches the maximum compression limit. At this time, the control button 43 is rotated again to make the limit rod 42 abut against the second limit plate 28, and then the control button 43 is released. The starting shaft 41 is withdrawn under the action of the return spring 44, but because it has been rotated before, the angle of the limit rod 42 relative to the first limit plate 27 along the length direction of the starting shaft 41 has changed. Therefore, the limit rod 42 will eventually abut against the upper end of the first limit plate 27 during this resetting process and be engaged with the second limit plate 28.

[0043] Specifically, when the door handle structure proposed in this embodiment is applied to the door body 1, when the limit rod 42 is engaged with the second limit plate 28, the two doors of the door body 1 are as follows: Figure 8 In the unlocked state shown in FIG. 1 , the handle body 2 can independently control one of the doors to be opened or closed. If the control knob 43 is rotated to rotate the limit rod 42 to the initial state and restored to the engagement with the first limit plate 27 under the action of the return spring 44, the two doors of the door body 1 are as shown in FIG. Figure 7In the interlocking state shown, the handle body 2 can control the synchronous opening and closing of the two doors at the same time, which greatly reduces the user's operation steps. It should be noted that whether the corresponding door body 1 is in the interlocking state of the two doors when the limit rod 42 is engaged with the two limit plates in different positions depends on the specific structure of the interlocking mechanism set up by itself, which may be opposite to the present embodiment in some other embodiments. In addition, in some other embodiments, the door structure applied by the handle structure can also be a left and right door structure or other types, and is not limited to the upper and lower door structures applied by the door handle structure in the present embodiment.

[0044] Furthermore, if Figure 3 , Figure 6 As shown, a second guide groove 29 matching the starting shaft 41 is provided in the connecting hole 26 at one end ring in the second mounting cavity 25, providing a precise guide path for the linear motion of the starting shaft 41 to ensure smooth motion, and the return spring 44 is abutted on the end wall of the second guide groove 29. The return spring 44 abuts against the end wall of the second guide groove 29, and while playing a reset role, it can also play a shock-absorbing and buffering effect when the starting shaft 41 moves, reducing noise and vibration, and improving the smoothness and comfort of operation, and a certain number of second structural plates 210 connected to the inner wall of the second mounting cavity 25 are evenly provided along the outer periphery of the second guide groove 29, which enhances the overall structural strength and stability of the mounting cavity, especially when bearing the lateral force generated by the movement of the starting shaft 41.

[0045] Furthermore, if Figure 4 , Figure 5 , Figure 8 As shown, the mounting seat 21 is U-shaped, and a certain number of mounting posts 211 fixedly connected to the door body 1 are provided along the inner contour of the mounting seat 21. The mounting posts 211 are arranged in an axisymmetric manner. This design not only disperses the force points and enhances the connection strength between the handle body 2 and the door structure, but also significantly improves the stability of the handle structure itself, and prevents the mounting part of the handle body 2 from loosening or deformation during frequent switching operations. Specifically, in this embodiment, one mounting post 211 is provided on each side above the mounting seat 21, and three mounting posts 211 are evenly provided below in accordance with the shape of the contour line, thereby ensuring a balanced distribution of force on the handle body 2. A reinforcing rib 241 adjacent to the mounting post 211 is provided between the end wall and the side wall of the first mounting cavity 24. The reinforcing rib 241 is adapted to the depth of the first mounting cavity 24 and extends outward by a certain length to be connected to the mounting post 211. The reinforcing rib 241 not only enhances the overall strength of the mounting seat 21, but also significantly enhances the stability and load-bearing capacity of the door handle structure proposed in this embodiment as a whole.

[0046] Furthermore, if Figure 4As shown, the handle 23 includes a joint end 231 connected to the mounting tube 22, and the joint end 231 is fixedly connected to a hand-holding rod 232. In the present embodiment, the hand-holding rod 232 is a hollow round rod whose upper end is sleeved and clamped with the joint end 231, while in other embodiments, a rectangular or other ergonomically shaped hollow rod can be selected to reduce the overall weight of the handle body 2. In addition, the hollow design also helps to dissipate heat, prevents users from being burned when holding the handle for a long time, and improves the user's operating experience. In addition, the lower end of the hand-holding rod 232 is provided with a corresponding cover 233 for sealing, so as to prevent dust, water vapor and other pollutants from entering the interior of the handle 23, thereby extending the service life of the handle body 2.

[0047] Embodiment 2:

[0048] In this embodiment, the difference from the embodiment is mainly in the structure of the first installation cavity 24, the second installation cavity 25 and the start shaft 41. For details, see Figure 9-10 First, a moving gear 45 is set at one end of the starting shaft 41 facing the box door to start the interlocking mechanism set on the control box door body. Obviously, the interlocking mechanism will also make corresponding structural changes, such as setting a rack on the corresponding specific locking member that can cooperate with the moving gear 45 to lock or unlock the two boxes.

[0049] Due to the presence of the movable gear 45, compared with Example 1, the present embodiment cancels the limiting structure composed of the limiting rod 42, the first limiting plate 27 and the second limiting plate 28, and sets a first guide groove 242 connected to the second guide groove 29 at the position passing through the center of the first mounting cavity 24. The first guide groove 242 is adapted to the axial diameter of the starting shaft 41, and first structural plates 243 connected to the inner wall of the first mounting cavity 24 are evenly arranged around the outer periphery of the first guide groove 242. The first structural plate 243 and the second structural plate 210 greatly increase the overall structural strength and stability of the handle body 2.

[0050] In addition, since the driving mode of the starting shaft 41 to the corresponding interlocking mechanism is changed from linear abutment to gear transmission connection, the reset spring 44 is eliminated in this embodiment compared with Embodiment 1. The user only needs to rotate the control button 43 to control the locking or unlocking of the two doors. Compared with Embodiment 1, the structure is simplified and the operating experience is better.

[0051] Principle of this utility model:

[0052] The electric oven door handle structure proposed by the utility model is suitable for a double-cooking cavity electric oven door provided with a corresponding interlocking mechanism. The user can activate the interlocking mechanism on the corresponding electric oven door by operating the interlocking starting mechanism on the handle body, so that the two independent oven doors are locked, and only one oven door handle is required for synchronous opening and closing. The interlocking starting mechanism is arranged in the handle body. In simple terms, the user starts or closes the interlocking mechanism on the oven door by rotating the control knob, and then chooses to operate the oven door installed with the handle body alone, or to operate the two oven doors locked as one at the same time. Compared with the double-cooking cavity oven door handle under the prior art, the user's operating convenience and usage experience are greatly improved.
