Detailed ways

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

In the related art, such as the side-sliding door cooking appliance of the microwave oven, the door body is closed through the cooperation of the door hook and the locking structure. The door hook is movably arranged on the door body through mechanisms such as elastic parts, resulting in a complex structure of the door body. .

Specifically, the door opening and closing system of cooking appliances such as microwave ovens in the related art includes main components such as the door body, door hook, front plate, bracket, etc., and the door hook moves along the ramp of the bracket as a whole, and finally snaps to the bracket. Behind the ramp, the door body can be closed. The whole process is driven by manpower or the inertia of the door body. There is no buffer design. The noise of closing the door is strongly related to the force of closing the door manually.

Slow-closing/soft-closing mechanisms are widely used in the field of furniture and home decoration. For example, adding a slow-closing system to doors or drawers can effectively reduce the risk of children being pinched by doors or drawers and improve user experience. In the field of home appliances, especially microwave ovens, steamers, ovens and other products, there are also slow-closing designs, which are mainly used in cooking utensils with pull-down doors. They are mainly set on the door hinges. The design concept refers to the furniture industry.

However, when facing a cooking appliance with a side sliding door, it is not easy to add a slow-closing design to the door hinge: on the one hand, for a cooking appliance with a small volume, the design space for the hinge position is very small, and it is difficult to arrange a suitable mechanism. And for microwave oven products, the risk of wave leakage will increase after the design of the door opening; on the other hand, unlike the pull-down door products, the door body rotation plane of the side-sliding door products is perpendicular to the plane that can be used for slow-closing door design, so it is necessary to design a plane The force transmission and direction conversion mechanism between them undoubtedly increases the design difficulty and design cost, reduces the feasibility, and is not easy to popularize and apply.

The most common side-sliding door microwave oven product is the non-slow-closing design, which adopts an integral door hook. The door hook consists of two parts: the upper and lower door hooks. The door hook is connected to the door body by the door hook spring. The bracket contacts and moves along the bracket as a whole. The bracket includes a slope. After the door hook passes through the slope of the bracket as a whole, it is stuck behind the slope of the bracket under the action of the spring tension of the door hook. At this point, the closing process is over, and the door opening process is the reverse of the above process.

For this reason, there has also been a slow-closing/soft-closing design for microwave ovens with side sliding doors. This design changes the original integral door hook design into two detachable parts. To trigger the slow closing system, the upper half of the door hook is similar to the traditional door hook, and is connected with the lower half of the door hook through the track, and maintains relative reciprocating motion. The upper part of the door hook is connected to the door body by the door hook spring, and is fixed behind the bracket slope 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 the spring and damper Working together, the door body is driven to close automatically, realizing the non-manpower slow closing process.

The microwave oven with non-slow-closing design in the related art adopts an integral door hook, the door body and the door frame are in direct contact, and there is no effective cushioning design during the contact period. Therefore, when the user closes the door forcefully, the closing noise will increase sharply , seriously affecting the user experience.

The slow-closing/soft-closing design for side-sliding door microwave ovens in the related art uses a split door hook and uses buckles, slides, springs, dampers, etc. to realize the slow-closing process, but the slow-closing system takes up a lot of space , in order to ensure sufficient spacing with other components, for models with different volumes, it is necessary to design different size and ratio solutions, which has poor versatility and high cost.

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

A cooking appliance according to an embodiment of the present application is described below with reference to the accompanying drawings.

As shown in FIGS. 1-14 , the cooking appliance according to the embodiment of the present application 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 .

The door body 10 is rotatably arranged on the box body to open or close the box body.

Specifically, there is a cooking cavity inside the box body, and the door body 10 is rotatably arranged on the box body to open or close the cooking cavity.

The first door hook 100 is disposed on the door body 10 . The locking base 200 is provided on the box body. The rotating block 300 is pivotably arranged on the locking base 200 between the locking position and the releasing position, the rotating block 300 is suitable for hooking the first door hook 100 in the locking position and allows the first door hook 100 to hook in the releasing position. The first door hook 100 is disengaged from the rotating block 300, and the rotating block 300 has a balance position between the locking position and the releasing position. The driving device 400 is configured to constantly drive the rotating block 300 to rotate in a direction away from the equilibrium position.

What needs to be added here is that "the driving device 400 is configured to constantly drive the rotating block 300 to rotate away from the equilibrium position." It means that when the rotating block 300 is located between the equilibrium position and the release position, the driving device 400 The rotating block 300 is constantly driven to rotate toward the release position. When the rotating block 300 is located between the equilibrium position and the locking position, the driving device 400 is constantly driving the rotating block 300 to rotate toward the locking position.

Specifically, when the rotating block 300 is in the release position as shown in Figure 1 and Figure 2, when the rotating block 300 is in the locking position as shown in Figure 9 and Figure 10, Figure 1-Figure 10 shows the rotation The process of turning the block 300 from the release position to the lock position.

As shown in Figures 1 to 10, 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, prompting the rotating block 300 to move from the release position Rotate to the equilibrium position. At this time, the driving device 400 applies a force to the rotating block 300 to rotate to the release position, that is, a force opposite to the closing direction of the door body 10, so as to ease the closing force of the door body 10 and prevent the door body from 10 closing force is too large, as the door body 10 continues to close, the rotating block 300 crosses the equilibrium position and rotates from the equilibrium position to the locking position. At this time, the driving device 400 applies force to the rotating block 300 The force of the rotation of the locking position, that is, the force in the same direction as the closing direction of the door body 10, makes the door body 10 close under the action of the driving device 400, and ensures that the door body 10 will not be opened arbitrarily.

As shown in Fig. 10-Fig. 1, in the process of opening the door body 10, the door body 10 rotates under the operation of the user, and rotates from the locked position to the equilibrium position. Applying a force to rotate to the locked position, that is, a force opposite to the opening direction of the door body 10, the user needs to overcome the reverse force exerted by the drive device 400 until the rotating block 300 passes the balance position, and from the balance position Rotate to the release position, at this time, the driving device 400 applies a force to the rotating block 300 to rotate to the release position, that is, the same force as the opening direction of the door body 10 , prompting the door body 10 to open quickly.

According to the cooking appliance of the embodiment of the present application, the first door hook 100 is arranged on the door body 10 by setting the locking base 200 , the rotating block 300 and the driving device 400 on the box body. The locking base 200 is provided on the box body. The rotating block 300 is pivotably arranged on the locking base 200 between the locking position and the releasing position, the rotating block 300 is suitable for hooking the first door hook 100 in the locking position and allows the first door hook 100 to hook in the releasing position. The first door hook 100 is disengaged from the rotating block 300 . Thus, the locking and releasing of the door body 10 can be realized, preventing the door body 10 from being opened arbitrarily when the user does not operate it, and enabling the door body 10 to be opened by the user's operation when needed.

And, by making the rotating block 300 have a balance position between the locking position and the releasing position. The driving device 400 is configured to constantly drive the rotating block 300 to rotate away from the equilibrium position. In this way, during the closing process of the door body 10, when the first door hook 100 just comes into contact with the rotating block 300, the strength of closing the door body 10 can be relieved first, so as to avoid excessive force when the door body 10 is closed, thereby reducing the force of the door body 10. Closing noise, avoiding the effects of pinching hands, etc., and after the rotating block 300 has crossed the balance position, the rotating block 300 can be rotated to the locked position under the action of the driving device 400, so that the door body 10 is driven by the driving device 400. Close under action, and prevent the door body 10 from opening arbitrarily at the same time. At the same time, the driving device 400 can keep the rotating block 300 at the release position after the door body 10 is opened, so as to prevent the rotating block 300 from rotating at will, so that the rotating block 300 can reliably cooperate with the first door hook 100 when the door body 10 is closed again.

In addition, since the locking base 200, the rotating block 300 and the driving device 400 are all arranged on the box body, the structures for cooperating with the first door hook 100 are all arranged on the box body, and the first door hook 100 only needs to be simply installed on the door body 10 without additionally setting other mechanisms. Compared with cooking utensils in the related art, the structure of the door body 10 can be greatly simplified and the size of the door body 10 can be reduced. Compared with the door body 10, it has a larger arrangement space, which can simplify the layout and assembly difficulty of the cooking appliance.

Therefore, the cooking appliance according to the embodiment of the present application can buffer the force of closing the door, and has the advantages of simple structure of the door body, easy layout and assembly, and the like.

A cooking appliance according to a specific embodiment of the present application will be described below with reference to the accompanying drawings.

In some specific embodiments of the present application, as shown in FIGS. and drive device 400.

Optionally, as shown in FIG. 13 , the first door hook 100 is fixed on the door body 10 . In this way, the first door hook 100 can be simply and directly fixedly installed on the door body 10, saving 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 first door The installation of the hook 100 is more stable and reliable.

Specifically, as shown in FIG. 2 , FIG. 4 , FIG. 6 , FIG. 8 , FIG. 10 and FIG. 11 , 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 need power supply, which can save costs such as circuit wiring.

More specifically, as shown in FIG. 2 , FIG. 4 , FIG. 6 , FIG. 8 , FIG. 10 and FIG. 11 , the driving device 400 includes two driving tension springs 410 . In this way, the two driving tension springs 410 can be used to exert force on the rotating block 300, which is beneficial to apply force components in different directions to the rotating block 300, and facilitates the rotating block 300 to rotate away from the equilibrium position.

Further, as shown in Fig. 2, Fig. 4, Fig. 6, Fig. 8, Fig. 10 and Fig. 11, the driving extension spring 410 has a fixed end and a movable end, and the movable ends of the two driving extension springs 410 are connected to the rotating block 300 And the connection position is set at intervals from the rotation axis of the rotating block 300 , and the fixed ends of the two driving tension springs 410 are both set on the locking base 200 at intervals. 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 arranged at intervals up and down. 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 up and down directions are shown by the arrows in the figure and are only for the convenience of expression and not limited to the actual installation direction). In this way, the two driving tension springs 410 can generate component forces in different directions on the rotating block 300, so as to promote the rotating block 300 to rotate away from the equilibrium position.

Furthermore, as shown in FIGS. 1-11 , 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 connecting end to the rotating axis of the rotating block 300 and passes through the rotating axis of the rotating block 300 . When the rotating block 300 is located between the release position and the equilibrium position, the resultant force of the two driving tension springs 410 is biased toward the release position by the rotation axis of the rotating block 300, and when the rotating block 300 is located between the equilibrium position and the equilibrium position When between the locking positions, the resultant force of the two driving tension springs 410 is biased toward the locking position by the rotation axis of the rotating block 300 . Taking the direction shown in the figure as an example, when the rotating block 300 is located 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, and when the rotating block 300 is located at the When between the balance 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 . In this way, the rotating block 300 can be facilitated to rotate in a direction away from the equilibrium position.

Advantageously, as shown in FIGS. 1-10 , the balance position is closer to the release position than the locking position. This can make the door body 10 easier to close, avoiding the situation that the user's strength or inertia is too small to cause the door body 10 to fail to close.

More advantageously, as shown in Fig. 1, Fig. 3, Fig. 5, Fig. 7, Fig. 9, and Fig. 11, a positioning groove 310 is provided on the rotating block 300, and the first door hook 100 of the rotating block 300 is in the locked position. It is suitable for hooking the positioning slot 310 and allowing the first door hook 100 to disengage from the positioning slot 310 in the release position. In this way, it is convenient for the rotating block 300 to cooperate with the first door hook 100 , and it is convenient for the rotating block 300 to release and lock the first door hook 100 .

Specifically, the inner walls of the positioning groove 310 are arc-shaped. In this way, the rotating block 300 can be easily rotated smoothly under the push of the first door hook 100, and mutual jamming can be avoided.

1-10 illustrate cooking appliances according to some examples of the present application. As shown in Fig. 1, Fig. 3, Fig. 5, Fig. 7 and Fig. 9, the cooking utensil also includes a damping device 500, the damping device 500 is arranged on the locking base 200, and the rotating block 300 is in the balance position and the There is a damping position between the locking positions. 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 . In this way, during the closing process of the door body 10, after the rotating block 300 has crossed the balance position, the damping device 500 can be used to decelerate the rotation of the rotating block 300, thereby damping the closing of the door body 10 and slowing down the speed of the door body 10. The closing speed reduces the force of collision between the door body 10 and the box body, so as to reduce the door closing noise and avoid pinching hands.

That is to say, during the closing process of the door body 10, when the rotating block 300 is rotated from the release position to the equilibrium position, the driving device 400 will slow down the closing speed and force. When the above-mentioned balance position is rotated from the damping position to the locking position, the damping device 500 plays a role in slowing down the speed and force of door closing. At this time, the driving device 400 needs to overcome the damping force generated by the damping device 500 to realize the door body 10 Therefore, the force and speed of closing the door can be slowed down in multiple processes of closing the door body 10, so as to realize the function of slow closing/soft closing.

In addition, when the rotating block 300 is between the equilibrium position and the damping position, the damping device 500 will not apply a damping force to the rotating block 300, and the transition between the equilibrium position and the damping position can be made , to prevent the first door hook 100 from suddenly encountering the damping force generated by the damping device 500 to cause a rebound, thereby preventing the first door hook 100 from colliding back and forth in the positioning groove 310 of the rotating block 300 and avoiding collision noise.

Specifically, as shown in Fig. 1, Fig. 3, Fig. 5, Fig. 7, Fig. 9 and Fig. 11, the cooking utensil also includes a swing block 600, which is connected to the damping device 500, and the swing block 300 is provided with a swing The groove 320 has a first stop wall 321 and a second stop wall 322 in the swing groove 320. The swing block 600 is swingably arranged in the swing groove 320. When the turn block 300 is in the release position, the swing block 600 and the first block The stopper wall 321 is spaced apart from and abuts against the second stopper wall 322 . When the swinging block 600 rotates from the damping position to the locking position, the swinging block 600 abuts against the first stopper wall 321 and abuts against the second stopper wall 322 . Walls 322 are spaced apart. Specifically, during the closing process of the door body 10, the swing block 600 is first spaced apart from the first stop wall 321. At this time, the swing block 600 is still relative to the damping device 500, and the damping device 500 does not generate a damping force. With the rotation of the rotating block 300, the first stop wall 321 gradually approaches the swinging block 600 until it completely fits with the swinging block 600. At this time, the force of the first door hook 100 to push the rotating block 300 to rotate can directly act on the rotating block 300. On the oscillating block 600 , the oscillating block 600 starts to rotate with the rotating block 300 relative to the damping device 500 , and the damping device 500 starts to generate a damping force. Therefore, the rotating block 300 can be connected to the damping device 500 through the swinging block 600 instead of being directly connected to the damping device 500 , so as to form a transition region between the equilibrium position and the damping position.

Advantageously, as shown in Fig. 2, Fig. 4, Fig. 6, Fig. 8 and Fig. 10, the cooking appliance further includes a compression spring 700, the compression spring 700 is arranged on the locking base 200, and the rotating block 300 is adjacent to the Squeeze the compression spring 700 in the locked position. 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 completely closed, thereby avoiding the direct collision between the door body 10 and the box body, further easing the closing speed and strength of the door body 10, and further avoiding closing the door. Noise, prevent pinching hands.
