Detailed implementation manners

[0039] This application is made based on the inventor's discovery and recognition of the following facts and problems:

[0040] In related technologies, for side-pull door cooking appliances such as microwave ovens, the closing of the door body is achieved through the cooperation of a door hook and a locking structure. The door hook is movably arranged on the door body through mechanisms such as elastic members, resulting in a complex structure of the door body.

[0041] Specifically, in related technologies, for cooking appliances such as microwave ovens, their door opening and closing systems include main components such as a door body, a door hook, a front panel, and a bracket. The door hook moves along the bracket ramp as a whole and finally gets stuck behind the bracket ramp, thereby achieving the closing of the door body. The whole process is driven by human force or the inertia of the door body, without a buffer design, and the closing noise is strongly related to the force of closing the door by hand.

[0042] Slow-closing / soft-closing mechanisms are widely used in the field of furniture and home decoration. For example, adding a slow-closing system to a room door or a drawer can effectively reduce the risk of children being pinched by the door or the drawer and improve the user experience. In the field of household appliances, especially in products such as microwave ovens, steam ovens, and ovens, there are also slow-closing designs, which are mainly applied to cooking appliances with downward-opening doors and are mainly arranged on the door hinge, and the design concept refers to the furniture industry.

[0043] However, when facing side-pull door cooking appliances, it is not easy to add a slow-closing design to the door hinge: on the one hand, for cooking appliances with a small volume, the available design space at the hinge position is very small, and it is not easy to arrange a suitable mechanism. Moreover, for microwave oven products, adding a door body opening will increase the risk of wave leakage; on the other hand, different from downward-opening door products, the rotation plane of the door body of side-pull door products is perpendicular to the plane available for slow-closing design. Therefore, a force transmission and direction conversion mechanism between the planes needs to be designed, which undoubtedly increases the design difficulty and design cost, reduces the feasibility, and is not easy to be popularized and applied.

[0044]

[0044] The most common non-slow-closing design for side-slide door microwave ovens is the integral door hook design. The door hook consists of upper and lower door hooks, and is connected to the door body by a door hook spring. During the closing process, the upper and lower door hooks contact the fixed bracket and move along the bracket as a whole. The bracket includes a slope. After the whole door hook passes through the slope of the bracket, it is stuck behind the slope of the bracket under the pulling force of the door hook spring, and the closing process ends here. The opening process is the reverse order of the above process.

[0045]

[0045] Therefore, a slow-closing / soft-closing design for side-slide door microwave ovens has also emerged. This design changes the original integral door hook design to two separable parts. The lower part of the door hook is fixed to the door body and is mainly used to trigger the slow-closing system. The upper part of the door hook is similar to the traditional door hook, is connected to the lower door hook through a track, and maintains relative reciprocating motion. The upper part of the door hook is connected to the door body by a door hook spring and is fixed behind the slope of the bracket after passing through the slope of the bracket. After the lower part of the door hook triggers the buckle, the buckle fastens the lower door hook, and under the combined action of the spring and the damper, the door body is driven to close automatically, realizing a non-manual slow-closing process.

[0046]

[0046] In the non-slow-closing design microwave oven in the related art, an integral door hook is adopted, and there is direct contact between the door body and the door frame. During the contact period, there is a lack of effective buffer design. Therefore, when the user closes the door with greater force, the closing noise will increase sharply, seriously affecting the user experience.

[0047]

[0047] In the slow-closing / soft-closing design for side-slide door microwave ovens in the related art, a split door hook is adopted, and components such as buckles, slides, springs, and dampers are used to realize the slow-closing process. However, this set of slow-closing system occupies a large space. To ensure sufficient space reserved for other components, different size ratio schemes need to be designed for different volume models, with poor versatility and high costs.

[0048]

[0048] That is to say, in the related art, regardless of whether a slow-closing / soft-closing structure is provided, the door hook needs to be installed on the door body through a special moving mechanism, resulting in a complex structure of the door body. Since the space of the door body itself is small, it will undoubtedly increase the layout and installation difficulty.

[0049]

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0052] The cooking appliance according to an embodiment of the present invention will be described below with reference to the drawings.

[0053] As Figures 1 - 14 shown, the cooking appliance according to an embodiment of the present invention includes a box body, a door body 10, a first door hook 100, a locking base 200, a rotating block 300, and a driving device 400.

[0054] The door body 10 is rotatably provided on the box body to open or close the box body.

[0055] Specifically, a cooking cavity is provided inside the box body, and the door body 10 is rotatably provided on the box body to open or close the cooking cavity.

[0056] The first door hook 100 is provided on the door body 10. The locking base 200 is provided on the box body. The rotating block 300 is pivotally provided on the locking base 200 between a locking position and a release position. The rotating block 300 is adapted to be hooked by the first door hook 100 in the locking position and allows the first door hook 100 to disengage from the rotating block 300 in the release position. The rotating block 300 has a balanced position between the locking position and the release position. The driving device 400 is configured to constantly drive the rotating block 300 to rotate in a direction away from the balanced position.

[0057] It should be noted here that "the driving device 400 is configured to constantly drive the rotating block 300 to rotate away from the equilibrium position" means that when the rotating block 300 is located between the equilibrium position and the release position, the driving device 400 constantly drives the rotating block 300 to rotate towards the release position, and when the rotating block 300 is located between the equilibrium position and the locking position, the driving device 400 constantly drives the rotating block 300 to rotate towards the locking position.

[0058] Specifically, when the rotating block 300 is in the release position as Figure 1 and Figure 2 shown, when the rotating block 300 is in the locking position as Figure 9 and Figure 10 shown, Figures 1 - 10 illustrates the process of the rotating block 300 rotating from the release position to the locking position.

[0059] As Figures 1 - 10 shown, during the closing process of the door body 10, the door body 10 rotates under the action of human hands or inertia, and the first door hook 100 contacts the rotating block 300, causing the rotating block 300 to rotate from the release position towards the equilibrium position. At this time, the driving device 400 applies a force to the rotating block 300 to rotate towards the release position, that is, a force opposite to the closing direction of the door body 10, to relieve the closing force of the door body 10 and prevent the closing force of the door body 10 from being too large. As the door body 10 continues to close, the rotating block 300 crosses the equilibrium position and rotates from the equilibrium position towards the locking position. At this time, the driving device 400 applies a force to the rotating block 300 to rotate towards the locking position, that is, a force in the same direction as the closing direction of the door body 10, so that the door body 10 closes under the action of the driving device 400 and ensures that the door body 10 will not open randomly.

[0060] As Figure 10 shown, during the opening process of the door body 10, the door body 10 rotates under the user's operation, from the locking position towards the equilibrium position. At this time, the driving device 400 applies a force to the rotating block 300 to rotate towards the locking position, that is, a force opposite to the opening direction of the door body 10. The user needs to overcome the reverse force applied by the driving device 400 until the rotating block 300 crosses the equilibrium position and rotates from the equilibrium position towards the release position. At this time, the driving device 400 applies a force to the rotating block 300 to rotate towards the release position, that is, a force in the same direction as the opening direction of the door body 10, to promote the rapid opening of the door body 10.

[0061] A cooking appliance according to an embodiment of the present invention is provided with a locking base 200, a rotating block 300, and a driving device 400 on the cabinet. The first door hook 100 is provided on the door body 10. The locking base 200 is provided on the cabinet. The rotating block 300 is pivotally provided on the locking base 200 between a locking position and a release position. The rotating block 300 is adapted to be hooked by the first door hook 100 at the locking position and allows the first door hook 100 to disengage from the rotating block 300 at the release position. Thus, the locking and release of the door body 10 can be realized, preventing the door body 10 from being opened randomly when the user does not operate and enabling the door body 10 to be opened by the user's operation when needed.

[0062] Moreover, by making the rotating block 300 have a balanced position between the locking position and the release position. The driving device 400 is configured to constantly drive the rotating block 300 to rotate in a direction away from the balanced position. In this way, during the closing process of the door body 10, when the first door hook 100 just contacts the rotating block 300, the closing force of the door body 10 can be relieved first, avoiding excessive closing force of the door body 10, thereby reducing the closing noise and preventing pinching hands, etc. And after the rotating block 300 passes the balanced position, the rotating block 300 can be rotated to the locking position under the action of the driving device 400, prompting the door body 10 to close under the action of the driving device 400, while preventing the door body 10 from being opened randomly. At the same time, the driving device 400 can keep the rotating block 300 in the release position after the door body 10 is opened, preventing the rotating block 300 from rotating randomly, facilitating reliable cooperation between the rotating block 300 and the first door hook 100 when the door body 10 is closed again.

[0063] In addition, since the locking base 200, the rotating block 300, and the driving device 400 are all provided on the cabinet, and the structures for cooperating with the first door hook 100 are all provided on the cabinet, the first door hook 100 only needs to be simply installed on the door body 10 without the need to additionally set up other mechanisms. Compared with the cooking appliances in the related art, the structure of the door body 10 can be greatly simplified, the size of the door body 10 can be reduced, and since the cabinet has a larger layout space than the door body 10, the layout and assembly difficulty of the cooking appliance can be simplified.

[0064] Therefore, the cooking appliance according to the embodiment of the present invention can buffer the closing force, has the advantages of simple door body structure, easy layout and assembly, etc.

[0065] Next, the cooking appliance according to the specific embodiment of the present invention will be described with reference to the accompanying drawings.

[0066] In some specific embodiments of the present invention, such as Figures 1 - 14As shown, the cooking appliance according to an embodiment of the present invention includes a box body, a door body 10, a first door hook 100, a locking base 200, a rotating block 300, and a driving device 400.

[0067] Optionally, as Figure 13 shown, the first door hook 100 is fixed to the door body 10. In this way, the first door hook 100 can be simply and directly fixed to the door body 10, eliminating other movable or elastic mechanisms, simplifying the assembly process of the first door hook 100, simplifying the structure of the door body 10, and making the installation of the first door hook 100 more stable and reliable after installation.

[0068] Specifically, as Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 10 and Figure 11 shown, the driving device 400 is an elastic member. In this way, the structure of the driving device 400 can be simplified, the cost of the driving device 400 can be reduced, and the driving device 400 does not require power supply, so the cost of circuit wiring and the like can be saved.

[0069] More specifically, as Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 10 and Figure 11 shown, the driving device 400 includes two driving tension springs 410. In this way, the two driving tension springs 410 can apply force to the rotating block 300, which is beneficial to applying component forces in different directions to the rotating block 300 and facilitating the rotation of the rotating block 300 in a direction away from the equilibrium position.

[0070] Furthermore, as Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 10 and Figure 11As shown, the driving tension spring 410 has a fixed end and a movable end. The movable ends of the two driving tension springs 410 are both connected to the rotating block 300, and the connection positions are spaced from the rotation axis of the rotating block 300. The fixed ends of the two driving tension springs 410 are both provided on the locking base 200 and are spaced apart. Specifically, the rotation axis of the rotating block 300 is located at the upper part of the rotating block 300, and the connection position of the movable end is located at the lower part of the rotating block 300. In the vertical direction, the fixed end is located above the rotation axis of the rotating block 300, and the movable end is located below the rotation axis of the rotating block 300. The two fixed ends are spaced apart vertically. In the horizontal direction, the movable end and the fixed end are respectively located on both sides of the rotation axis of the rotating block 300 (the vertical direction is as shown by the arrow in the figure and is only for the convenience of description and not a limitation on the actual setting direction). This can enable the two driving tension springs 410 to generate component forces in different directions on the rotating block 300, facilitating the rotation of the rotating block 300 in a direction away from the equilibrium position.

[0071] Furthermore, as Figures 1 - 11 shown, the two driving tension springs 410 are configured such that when the rotating block 300 is in the equilibrium position, the resultant force passes through the rotation axis of the rotating block 300. Specifically, when the rotating block 300 is in the equilibrium position, the resultant force of the two driving tension springs 410 extends from the connection end towards the rotation axis of the rotating block 300 and passes through the rotation axis of the rotating block 300. When the rotating block 300 is between the release position and the equilibrium position, the resultant force of the two driving tension springs 410 is biased from the rotation axis of the rotating block 300 towards the release position. When the rotating block 300 is between the equilibrium position and the locking position, the resultant force of the two driving tension springs 410 is biased from the rotation axis of the rotating block 300 towards the locking position. Taking the direction shown in the figure as an example, when the rotating block 300 is between the release position and the equilibrium position, the resultant force of the two driving tension springs 410 is located above the rotation axis of the rotating block 300. When the rotating block 300 is between the equilibrium position and the locking position, the resultant force of the two driving tension springs 410 is located below the rotation axis of the rotating block 300. This can facilitate the rotation of the rotating block 300 in a direction away from the equilibrium position.

[0072] Advantageously, as Figures 1 - 10 shown, the equilibrium position is closer to the release position than the locking position. This can make it easier for the door body 10 to close and avoid the situation where the door body 10 fails to close due to too little user force or inertia.

[0073] Even more advantageously, as Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 9 、 Figure 11As shown, the rotating block 300 is provided with a positioning groove 310. When the rotating block 300 is in the locking position, the first door hook 100 is adapted to hook the positioning groove 310, and when in the release position, the first door hook 100 is allowed to disengage from the positioning groove 310. This facilitates the cooperation between the rotating block 300 and the first door hook 100, and facilitates the release and locking of the first door hook 100 by the rotating block 300.

[0074] Specifically, the inner walls of the positioning groove 310 are all arc-shaped surfaces. This facilitates the smooth rotation of the rotating block 300 under the push of the first door hook 100, avoiding jamming with each other.

[0075] Figures 1 - 10 Fig. shows a cooking appliance according to some examples of the present invention. As Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 and Fig. 9 show, the cooking appliance further includes a damping device 500. The damping device 500 is provided on the locking base 200. The rotating block 300 has a damping position between the balanced position and the locking position. When the rotating block 300 rotates from the damping position to the locking position, the damping device 500 decelerates the rotation of the rotating block 300. This can, during the closing process of the door body 10, after the rotating block 300 passes the balanced position, use the damping device 500 to decelerate the rotation of the rotating block 300, thereby damping the closing of the door body 10, slowing down the closing speed of the door body 10, reducing the force of the door body 10 colliding with the cabinet, thus reducing the closing noise and avoiding pinching hands.

[0076] That is to say, during the closing process of the door body 10, when the rotating block 300 rotates from the release position to the balanced position, the driving device 400 plays a role in slowing down the closing speed and force. When the rotating block 300 passes the balanced position and rotates from the damping position to the locking position, the damping device 500 plays a role in slowing down the closing speed and force. At this time, the driving device 400 needs to overcome the damping force generated by the damping device 500 to achieve the closing of the door body 10, so that the closing force and speed can be slowed down during multiple processes of closing the door body 10, realizing the function of slow / soft closing of the door.

[0077] In addition, when the rotating block 300 is between the balanced position and the damping position, the damping device 500 does not apply a damping force to the rotating block 300. The rotation between the balanced position and the damping position can be used for transition, avoiding the first door hook 100 suddenly encountering the damping force generated by the damping device 500 and causing rebound, thus avoiding the first door hook 100 colliding back and forth in the positioning groove 310 of the rotating block 300 and avoiding collision noise.

[0078] Specifically, asFigure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 9 and Figure 11 As shown in , , and , the cooking appliance further includes a swing block 600. The swing block 600 is connected to a damping device 500. A swing groove 320 is provided on the rotating block 300. The swing groove 320 has a first stop wall 321 and a second stop wall 322. The swing block 600 is swingably disposed in the swing groove 320. When the rotating block 300 is in the release position, the swing block 600 is spaced from the first stop wall 321 and abuts against the second stop wall 322. When the swing block 600 rotates from the damping position to the locking position, the swing block 600 abuts against the first stop wall 321 and is spaced from the second stop wall 322. Specifically, during the closing process of the door body 10, the swing block 600 is first spaced from the first stop wall 321. At this time, the swing block 600 is stationary relative to the damping device 500, and the damping device 500 does not generate a damping force. As the rotating block 300 rotates, the first stop wall 321 gradually approaches the swing block 600 until it completely fits with the swing block 600. At this time, the force that the first door hook 100 exerts to push the rotation of the rotating block 300 can directly act on the swing block 600 through the rotating block 300. The swing block 600 begins to rotate relative to the damping device 500 together with the rotating block 300, and the damping device 500 begins to generate a damping force. Thus, the rotating block 300 can be connected to the damping device 500 through the swing block 600 instead of being directly connected to the damping device 500, which is convenient for forming a transition region between the balance position and the damping position.

[0079] Advantageously, as Figure 2 , Figure 4 , Figure 6 , Figure 8 and Figure 10 shown, the cooking appliance further includes a compression spring 700. The compression spring 700 is disposed on the locking base 200. When the rotating block 300 is adjacent to the locking position, the compression spring 700 is compressed. In this way, the compression spring 700 can be used to buffer the rotation of the rotating block 300 when the door body 10 is adjacent to being completely closed, thereby preventing the door body 10 from directly colliding with the cabinet, further alleviating the speed and force of the closing of the door body 10, further avoiding closing noise, and preventing pinching hands.

[0080] Figures 1 - 12 shows a cooking appliance according to some examples of the present invention. As Figures 1 - 12As shown, the cooking appliance further includes a second door hook 800, a sliding block 900, and a sliding driving device 1000. The second door hook 800 is provided on the door body 10. The sliding block 900 is slidably provided on the locking base 200 between a stop position and a disengaged position. The sliding block 900 is adapted to hook the second door hook 800 in the stop position and allows the second door hook 800 to disengage from the sliding block 900 in the disengaged position. The sliding driving device 1000 constantly drives the second door hook 800 to move towards the stop position. In this way, the second door hook 800 can be locked by the sliding block 900 to prevent the door body 10 from being opened randomly.

[0081] Advantageously, as shown in Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 10 and Figure 12 , the sliding driving device 1000 is an elastic member. Specifically, the sliding driving device 1000 is a tension spring. In this way, the cost of the sliding driving device 1000 can be saved.

[0082] Specifically, as shown in Figure 13 , the second door hook 800 is fixed to the door body 10.

[0086] Further, a communication chute penetrating the locking base 200 in the thickness direction is provided on the locking base 200, and the driving tension spring 410 is connected to the rotating block 300 through the communication chute. This facilitates the connection between the rotating block 300 and the driving tension spring 410.

[0087] The locking base 200 is provided with a locking limit post and a release limit post. When the rotating block 300 rotates to the locking position, it abuts against the locking limit post, and when it rotates to the release position, it abuts against the release limit post.

[0088] The locking base 200 is installed with an outer cover 1200, and the outer cover 1200 covers the rotating block 300. In this way, the outer cover 1200 can be used to protect the rotating block 300, improving the stability and reliability of the rotating block 300.

[0089] Guide surfaces are provided on the first door hook 100, the second door hook 800, and the sliding block 900. This enables the cooperation between the first door hook 100 and the rotating block 300, as well as between the second door hook 800 and the sliding block 900, to be more smooth.

[0090] Hook columns for fixing springs are provided on the locking base 200, the sliding block 900, and the rotating block 300. This facilitates the installation of the springs.

[0091] A compression spring seat is provided on the locking base 200. A compression spring groove is provided on the compression spring seat, and a limit post is provided in the compression spring groove. The compression spring 700 is fitted in the compression spring groove and sleeved outside the limit post. This facilitates the installation of the compression spring 700.

[0092] An installation groove communicating with the swing groove 320 is further provided on the rotating block 300. The swing block 600 has a rotating shaft portion, and the rotating shaft portion is rotatably fitted in the installation groove. This facilitates the swingable installation of the swing block 600.
