Detailed Description

The following detailed description of specific embodiments of the invention refers to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and explanatory of the invention and are not restrictive thereof.

The control panel driving mechanism and the cooking appliance according to the present invention will be described with reference to the accompanying drawings, which enable the control panel to be horizontally moved and turned over, and are low in cost, compact in structure, and convenient for loading and unloading the water storage box.

The cooking utensil is provided with the water storage box to steam and roast food, so that the food has delicious taste, is nutritional and healthy, and is favored by more and more consumers. Generally, the water storage box is hidden behind the control panel, is arranged at the upper part of the inner container of the steam box and is adjacent to the control panel, so that the integral aesthetic feeling of the cooking utensil is ensured, and the water storage box is convenient to clean and add water. When water needs to be added or the water needs to be cleaned, the position of the control panel needs to be adjusted through the control panel driving mechanism, and the water storage box is exposed. The existing control panel driving mechanism is often required to be provided with a longer push rod, so that the mechanism occupies a larger space, and the required space is larger when the control panel is turned over, so that the integration level of a cooking appliance and the use experience of a user are influenced. Therefore, how to improve the integration of the cooking appliance and the use experience of the user is a considerable problem.

For this reason, referring to fig. 1 to 11, in order to enable an improvement in the integration of the cooking appliance and the user experience, the inventors of the present application provide a control panel driving mechanism including: mount 100, pushrod 200, and pivot link 300

Specifically, the mounting seat 100 is formed with a linear limiting groove 1, the mounting seat 100 is used as a fixed end of the control panel driving mechanism, and the control panel driving mechanism is conveniently mounted in the cooking utensil through the mounting seat 100;

a push rod 200, the push rod 200 extending from the mounting base 100 and including a push rod pivoting end 210 pivotally connected to the control panel 400 for driving the control panel 400 to move. The push rod 200 provides a driving force for the movement of the control panel 400, and the control panel 400 can perform a pivoting motion relative to the push rod 200, so that the control panel 400 can be switched to different angles to facilitate the water adding, cleaning or closing of the water storage box; and

a pivoting link 300 having a limiting protrusion end 2 slidably installed in the linear limiting groove 1 and a link pivoting end 3 pivotally connected to the control panel 400, the pivoting link 300 being connected between the mounting base 100 and the control panel 400, the limiting protrusion end 2 being located in the linear limiting groove 1 and being movable within the groove length range of the linear limiting groove 1, the control panel 400 being pivotally movable relative to the pivoting link 300 by the link pivoting end 3;

wherein, the push rod pivoting end 210 is configured to reciprocate along the groove length direction L1 of the linear limit groove 1 and drive the control panel 400 to turn around the link pivoting end 3 when the limit protruding end 2 stops at the linear limit groove 1.

It is understood that the control panel 400 includes two motion paths of linear movement and inversion, as shown in fig. 1 and 2, and on one hand, the push rod 200 serves as a driving element to provide driving force for the linear movement and inversion of the control panel 400. The pivot link 300 as a follower member is capable of following the push rod pivot end 210 to move linearly in the slot length direction L1, thereby completing a linear movement path of the control panel. On the other hand, the linear moving distance of the control panel 400 is limited due to the fitting relationship of the limit projection 2 and the linear limit groove 1. The control panel 400 comprises two pivotal connection points connected with the push rod pivotal end 210 and the link rod pivotal end 3, when the limit protrusion end 2 is stopped at the linear limit groove 1, the link rod pivotal end 3 is used as a fixed end, the push rod 200 can continuously move linearly, so that the push rod pivotal end 210 is used as a moving end, and the interaction of the link rod pivotal end 3 and the push rod pivotal end 210 enables the control panel 400 to turn around the link rod pivotal end 3, thereby completing the turning path of the control panel 400, thereby facilitating the water adding and cleaning operations of the water storage box, wherein the linear movement refers to a movement along a linear direction.

Alternatively, the mounting seat 100 is used for mounting the push rod 200 and the pivot link 300, and the mounting seat 100 may be a box-type structure, and the mounting push rod 200 and the pivot link 300 are mounted in the box body and can extend out of the box body, so that the mounting and fixing firmness of the mounting push rod 200 and the pivot link 300 can be improved. The mounting seat 100 may also have a plate-shaped structure, for example, the mounting seat 100 may include a base portion capable of being connected to a cooking appliance and a seat portion extending from the base portion, wherein the base portion may be fixed to the cooking appliance by bolts, the linear limiting groove 1 is located on the seat portion, and the mounting push rod 200 and the pivot link 300 are connected to the seat portion, so that the volume of the mounting seat 100 can be reduced and the integration level can be improved. The number of the mounting seats 100 may be one, two or more, wherein two mounting seats 100 can ensure stable mounting of the control panel 400 and reduce the occupied space. The mount 100 may be an integral structure or a separate structure, and is not particularly limited herein.

Alternatively, the push rod 200 can drive the control panel 400 to move, wherein the push rod 200 can be a direct-drive element, for example, a power push rod, which includes a fixed end fixedly mounted on the mounting seat 100 and a movable end formed with a pivot end 210, and the movable end can move linearly, so that the control panel 400 can be pushed to move linearly and turn. The push rod 200 may also be an indirect driving element, for example, both ends of the push rod 200 in the rod length direction are movable ends, and when the control panel 400 is driven, the push rod 200 is controlled to move linearly as a whole by other driving components. Therefore, the push rod 200 can be prevented from being too long, the occupied space of the mechanism is reduced, and the integration level of the driving mechanism of the control panel is improved. In addition, the push rod 200 may be a straight rod or a bent rod with a bent end, and is not limited in particular.

Alternatively, the pivot link 300 may be an integral sheet structure, and the limit projection end 2 and the link pivot end 3 are respectively located at two ends of the sheet structure, so that the processing is convenient, and the installation cost is reduced. The pivot connecting rod 300 can be a split structure, the end of the pivot connecting rod 300 can be provided with a mounting hole, the limiting protruding end 2 can be a pin, and the pin is mounted in the mounting hole, so that the pivot connecting rod 300 and the pin can be of commercially available structures respectively, and the production cost is reduced.

Alternatively, the control panel 400 may have a panel length direction L2, a panel height direction H and a panel width direction W, wherein, in order to ensure that the control panel 400 can perform both linear movement and flipping actions, the push rod pivot end 210 and the link pivot end 3 are disposed in different panel height directions H, such that, when the link pivot end 3 stops linear movement, the push rod pivot end 210 can push the control panel 400 to flip, and the positions of the push rod pivot end 210 and the link pivot end 3 in the panel length direction L2 and the panel width direction W may be the same or different.

In order to improve the integration and stowability of the control panel 400 after being flipped, the pivot link 300 is designed, and in one embodiment, the pivot link 300 includes: a link straight bar portion 310 extending in the slot length direction L1; and a link bent part 320 having one end connected to the link straight part 310 and the other end extended away from the push rod 200 and formed as a link pivoting end 3, as shown in fig. 2 and 3. The straight rod portion 310 of the connecting rod may be a straight plate in a plate shape and extends along the slot length direction L1, so that the space occupation ratio can be reduced and the integration of the mechanism can be improved. One end of the link straight rod portion 310 in the rod length direction is connected to the link curved rod portion 320, and the link pivoting end 3 of the link curved rod portion 320 is far away from the push rod 200, which can be understood as that the link pivoting end 3 and the push rod 200 are respectively arranged at two ends of the link straight rod portion 310, that is, the link pivoting end 3, the link straight rod portion 310 and the push rod 200 are sequentially arranged at intervals in the plate height direction H, so that when the pivoting link 300 is fixed, the link pivoting end 3 is prevented from limiting the turning angle of the control panel 400, and the control panel 400 can be turned over by 90 degrees, as shown in fig. 10, and can be parallel to the groove length direction L1. Thus, the integration level and the storage property of the control panel 400 are improved, and the occupied space is reduced.

Further, in an embodiment, the connecting rod straight rod portion 310 is spaced apart from the linear limiting groove 1, and the limiting protrusion end 2 is located at the rod end portion of the connecting rod straight rod portion 310 and penetrates through the linear limiting groove 1, as shown in fig. 1. It can be understood that the connecting rod straight rod part 310 can be arranged in parallel with the linear limiting groove 1, and the limiting protruding end 2 can be vertically inserted into the rod end part of the connecting rod straight rod part 310 and penetrates through the linear limiting groove 1, so that the smoothness of the linear movement of the connecting rod straight rod part 310 is ensured, the pivoting connecting rod 300 can be limited and fixed, and the structure is simple and the integration level is high.

In order to improve the integration of the control panel driving mechanism, in one embodiment, the push rod 200 has a straight rod shape and is arranged to extend in the slot length direction L1, and the link pivot end 3 is formed at the rod end portion of the push rod 200, as shown in fig. 2 and 5.

Further, the push rod 200 may include oppositely disposed push rod end plates 230 and a push rod side plate 240 connected between the two push rod end plates 230, such that the push rod 200 may have a v-21274h-shaped structure and be formed with a v-21274h-shaped receiving space, in which the connecting rod straight rod part 310 may be located.

To further increase the compactness of the connection between the pusher pivoting end 210, the link pivoting end 3 and the control panel 400. In one embodiment, the control panel driving mechanism further includes a pivot mount 4 mounted on the control panel 400, the push rod pivot end 210 and the link pivot end 3 are integrated by the pivot mount 4, and the pivot mount 4 may include: a seat housing 41 surrounding the link accommodating chamber 4101 for accommodating the link pivoting end 3 and the push rod accommodating chamber 4102 for accommodating the push rod pivoting end 210, wherein the seat housing 41 may be integrally formed on the control panel 400, or may be assembled with the control panel 400 by means of bolts or welding; a link pin shaft 42 penetrating the seat housing 41 and the link pivot end 3 to pivotally connect the control panel 400 and the pivot link 300; and a push rod pin 43 passing through the seat housing 41 and the push rod pivot end 210 to pivotally connect the control panel 400 to the push rod 200, as shown in fig. 2 and 4.

Further, in order to ensure smooth turning of the control panel 400, in an embodiment, the control panel 400 includes a seat mounting surface 410 for mounting the pivot mounting seat 4, and a distance M1 between the pivot center line of the link pin 42 and the seat mounting surface 410 is smaller than a distance N1 between the pivot center line of the push lever pin 43 and the seat mounting surface 410, as shown in fig. 2, 4 and 11. The control panel 400 includes a seat mounting surface 410 facing the control panel driving mechanism, and it is understood that the control panel 400 performs a pivotal motion with the link pin shaft 42 as a pivotal center, the pivotal center line of the push rod pin shaft 43 should be disposed on the circumferential surface with the link pin shaft 42 as a center, and the distance M1 is smaller than the distance N1, so that the required length of the push rod 200 is reduced, thereby reducing the occupied space of the push rod 200 and ensuring that the control panel 400 can be turned to be parallel to the link straight rod portion 310.

Further, in order to reduce energy consumption, in an embodiment, a torsion spring 5 for energy storage and sleeved on the push rod pin 43 is disposed in the push rod accommodation chamber 4102, and one end of the torsion spring 5 abuts against the seat housing 41 and the other end abuts against the push rod 200, as shown in fig. 2 and 4.
