Detailed Description

In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.

A cover assembly 100 of a cooking appliance and a cooking appliance 300 according to some embodiments of the present invention are described below with reference to fig. 1 to 23.

Example 1:

as shown in fig. 1, 3, 4, 5 and 6, the embodiment of the first aspect of the present invention proposes a cover assembly 100 of a cooking appliance for being covered on a pot 400 of the cooking appliance and being detachable and rotatable from the pot 400, the cover assembly 100 of the cooking appliance including a cover body 110, a float 120 and a slider 130. The slider 130 is capable of reciprocating between a first position and a second position. Therefore, by reasonably limiting the cooperation structure of the float 120 and the slider 130, before the slider 130 moves to the second position, the slider 130 blocks the float 120 so that the float 120 cannot float, and when the slider 130 moves to the second position, the limitation of the slider 130 on the float 120 is released so as to release the space for the float 120 to float. That is, the slider 130 can stop the float 120 to prevent the float 120 from floating both in the first position and in a position between the first position and the second position of the slider 130. And only when the slider 130 moves to the second position, the restriction of the slider 130 to the float 120 is released to release the space where the float 120 floats.

Further, the first position is a position of the slider 130 when the cover assembly 100 and the pot 400 of the cooking appliance are separable or in a separated state, and the second position is a position of the slider 130 when the cover assembly 100 and the pot 400 of the cooking appliance are screwed in place. Here, the fact that the cover assembly 100 of the cooking appliance is separable from the pot 400 means that the cover assembly 100 of the cooking appliance is placed on the pot 400 and the cover assembly 100 of the cooking appliance is not fastened, the cover assembly 100 of the cooking appliance can be taken off from the pot 400, the fact that the cover assembly 100 of the cooking appliance is separated from the pot 400 means that the cover assembly 100 of the cooking appliance is not separated from the pot 400, for example, when the cover assembly 100 of the cooking appliance is provided with a cover tooth or a clamp, the pot 400 is provided with a pot tooth or a flanging, the cover assembly 100 of the cooking appliance and the pot 400 are fastened, or the cover assembly 100 of the cooking appliance and the pot 400 are fastened, the clamp and the flanging of the pot 400 are fastened, and the cover assembly 100 of the cooking appliance is fastened on the pot 400.

The arrangement can effectively solve the problem that the cover body assembly 100 of the cooking utensil is not screwed in place and is pressed in the related art, and is beneficial to improving the use safety and reliability of the cooking utensil 300.

It will be appreciated that the slider 130 is capable of reciprocating between a first position that limits the float 120 from floating and a second position that releases the limit on the float 120. Therefore, when the slider 130 is at a position other than the second position, the float 120 is in a state of being limited to float, that is, when the lid assembly 100 of the cooking appliance is not covered on the pan 400 or the lid is not covered on the pan 400 and is not started to rotate, the float 120 cannot float until the slider 130 is limited, and when the lid assembly 100 of the cooking appliance and the pan 400 are rotated, the float 120 is continuously limited by the slider 130 and cannot float, so that the interior of the cooking appliance 300 is always communicated with the external environment, the float 120 cannot float due to the air pressure in the cooking appliance 300, and the limitation on the float 120 is not released until the lid assembly 100 of the cooking appliance and the pan 400 are rotated in place, thereby fundamentally solving the problem that the interior of the cooking appliance 300 is pressurized due to the fact that the lid assembly 100 of the cooking appliance is not rotated in place.

Example 2:

as shown in fig. 13 and 14, according to one embodiment of the present invention, the features defined in any of the above embodiments are included, and further: one end of the sliding block 130 is provided with a stop part 132, when the sliding block 130 is positioned at the first position, the stop part 132 at least abuts against a part of the floater 120, when the sliding block 130 is positioned at the second position, the stop part 132 is away from the floater 120, the other end of the sliding block 130 is provided with a first matching convex part 134, and the sliding block 130 realizes reciprocating motion through the first matching convex part 134.

In detail, the slider 130 is provided with a stopper 132, and the slider 130 restricts the float 120 from floating by the stopper 132. For example, when the slider 130 is in the first position, the stopper 132 abuts at least a portion of the float 120 to function as a stopper for the float 120 to float upward. For example, when the slider 130 is at the second position, the stopper 132 is retracted from the float 120 (e.g., the stopper 132 is located at the circumferential side of the float 120) to release the external force of the slider 130 acting on the float 120 to release the space for the float 120 to float. In addition, the other end of the slider 130 is provided with a first engagement protrusion 134, the first engagement protrusion 134 moves within a slide way 410 of the pot 400 of the cooking appliance, and the first engagement protrusion 134 is engaged with a first engagement portion 412 of the pot 400 so that the slider 130 can move between a first position and a second position.

In the present embodiment, when the slider 130 is in the first position, the stopper 132 abuts against a portion of the top of the float 120.

In other embodiments, the stop 132 abuts the entire top of the float 120 when the slider 130 is in the first position.

Specifically, the stop portion 132 includes a stop wall, and the stop wall is adapted to the outer sidewall of the float 120, so that the occurrence probability of interference between the stop portion 132 and the float 120 when the float 120 floats can be reduced, which is beneficial to reducing the requirements on the machining precision and the assembly precision of the slider 130 and the float 120, and further is beneficial to reducing the production cost of the product. And this arrangement reduces the gap between the float 120 and the stopper 132 while securing the effectiveness of the float 120 in floating, so as to enhance the guiding action of the stopper 132 on the float 120 when the float 120 floats, effectively defining the floating path of the float 120.

Specifically, the blocking wall is located at the end of the slider 130 facing the float 120.

In the present embodiment, as shown in fig. 14, a portion of the end of the slider 130 facing the float 120 is configured as a blocking wall. In other embodiments, the end of the slider 130 facing the float 120 is entirely configured as a retaining wall.

Example 3:

as shown in fig. 1, 3 and 4, according to one embodiment of the present invention, the features defined in any of the above embodiments are included, and further: the cover assembly 100 of the cooking apparatus is provided with an elastic member 190, and the elastic member 190 is connected to the slider 130, so that the slider 130 returns to the first position when in the second position.

In detail, the cover assembly 100 of the cooking appliance further includes an elastic member 190, the elastic member 190 being connected to the slider 130, the elastic member 190 providing a power support for the slider 130 to return from the second position to the first position, and further providing a structural guarantee for the slider 130 to be capable of reciprocating between the first position and the second position.

Example 4:

as shown in fig. 1, 3 and 4, according to one embodiment of the present invention, the features defined in any of the above embodiments are included, and further: the cover assembly 100 of the cooking appliance further includes: the self-locking member 160 is movably connected with the cover body 110, the self-locking member 160 has a locking position and a releasing position, the first end 161 of the self-locking member is matched with the float 120, when the self-locking member 160 is positioned at the locking position, the second end of the self-locking member is locked by the pot 400, and when the float 120 floats, the first end 161 of the self-locking member is locked.

In detail, the cover assembly 100 of the cooking appliance further includes a self-locking member 160. The self-locking member 160 is movably connected with the cover body 110, i.e., the self-locking member 160 can move relative to the cover body 110 to switch between a locking position and a releasing position. By defining the mating structure of the latch 160, the float 120, and the pan 400 such that the latch 160 is in the latched position and the float 120 latches the first end 161 of the latch when floating, the pan 400 latches the second end of the latch. That is, the float 120 and the pot 400 are matched to realize double locking of the self-locking member 160, and the cover assembly 100 of the cooking appliance cannot rotate relative to the pot 400 of the cooking appliance, so that the cover cannot be forcibly opened, the safety protection during high pressure is improved, the forced opening of the cover by a user is avoided, and the safety is stronger.

Further, as shown in fig. 15, 16 and 21, the float 120 is provided with a connecting wall 122, the self-locking member 160 is provided with a connecting groove 162, and a part of the self-locking member 160 is recessed to form the connecting groove 162, and the float 120 floats upward to make the connecting groove 162 be clamped with the connecting wall 122. That is, the connecting wall 122 cooperates with the connecting slot 162 to limit the movement of the self-locking member 160 from the locking position to the releasing position when the float 120 floats. When the float 120 is in a floating state and a user opens the cap forcibly, the self-locking member 160 cannot move due to the blocking action of the float 120 on the self-locking member 160, and the locking of the self-locking member 160 at the locking position and the locking of the float 120 on the self-locking member 160 form double locking, so that the safety is stronger.

Example 5:

as shown in fig. 1, 5, 6, 7, 8, 9, 10, 11, 17, 18, 19 and 20, according to one embodiment of the present invention, the features defined in any of the above embodiments are included, and further: the cover assembly 100 of the cooking appliance further includes: the unlocking piece 170 is movably connected with the cover body 110, the unlocking piece 170 is configured to drive the self-locking piece 160 to move relative to the cover body 110, and when the floater 120 falls back, the unlocking piece 170 can drive the self-locking piece 160 to switch from the locking position to the releasing position.

In detail, if the float 120 is forcibly opened by the user in the floating state, the self-locking member 160 cannot move due to the blocking effect of the float 120 on the self-locking member 160, and at this time, the user can only press the unlocking member 170 to open the cover, and the force applied by the hand to the self-locking member 160 is much smaller than that generated by the related art (in which the cooking utensil is not provided with the unlocking member), and the force component generated by rotating the pot cover by the hands to the slide block is much smaller, so that the user cannot deform the slide block 130 and the float 120 easily due to the smaller force, the cover cannot be forcibly opened, the safety protection in high pressure is improved, and the forced opening of the cover by the user is avoided. In addition, when the float 120 falls back, the self-locking member 160 can be driven to switch from the locking position to the releasing position by pressing the unlocking member 170, and at this time, the lid assembly is rotated again to separate the lid assembly from the pot 400.

Further, as shown in fig. 3 and 4, the elastic member 190 is disposed between the slider 130 and the self-locking member 160, the elastic member 190 is in a normal compression state, and elastic compression force of the elastic member 190 acts on the slider 130 and the self-locking member 160, respectively. By reasonably defining the matching structure of the elastic member 190, the sliding block 130 and the self-locking member 160, when the elastic member 190 is in a normal compression state, the elastic compression force of the elastic member 190 pushes the sliding block 130 towards the center direction of the cover assembly 100 of the cooking appliance, and at the same time, the elastic compression force of the elastic member 190 pushes the self-locking member 160 towards the center direction of the cover assembly 100 away from the cooking appliance. The arrangement achieves the purpose of pushing the sliding block 130 and the self-locking piece 160 simultaneously by using the elastic piece 190, reduces material investment under the condition that the sliding block 130 and the self-locking piece 160 work normally, and is beneficial to reducing the production cost of products.
