Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and more specifically, to a cooking utensil. Background Technology

[0002] With the improvement of living standards, automated cooking equipment has gradually entered the public eye and is loved by many users due to its user-friendly operation. Among them, the stir-fry machine is one such example. The stir-fry machine uses a motor to drive the stirring blade to rotate, thereby realizing the stir-frying function of ingredients.

[0003] In related technologies, a cooking machine includes a pot body and a top cover, with a stirring blade installed inside the pot. The stirring blade rotates within the pot, thus stir-frying the ingredients inside.

[0004] However, the cooking machines in this technology require the top cover to be removed first, and then the stirring blades to move forward and backward manually, which is cumbersome to operate. Utility Model Content

[0005] This utility model provides a cooking appliance to solve the problem in related technologies where the top cover must be removed first, and then the stirring blade must be manually moved forward and backward, which leads to cumbersome operation.

[0006] This utility model provides a cooking appliance, comprising: a pot body; a lid, which is closable and covers the top of the pot body; a stirring assembly, including a stirring blade, a driving member, a connecting member, and a first resetting member, wherein the stirring blade is rotatably disposed within the pot body, the connecting member is movably disposed within the pot body, and the connecting member has a driving position for connecting the driving shaft of the driving member to the stirring blade and a separating position for separating the driving shaft from the stirring blade; and a forward / reverse blade assembly, including a pressing member, which is floatingly disposed within the pot body, and is drivenly connected to the connecting member to move the connecting member; wherein, during the process of the lid being placed on the pot body, the lid presses down on the pressing member, and the pressing member drives the connecting member from the separating position to the driving position; and when the lid is opened from the pot body, the first resetting member drives the connecting member from the driving position to the separating position.

[0007] Applying the technical solution of this utility model, the cooking appliance includes a pot body, a top cover, a stirring assembly, and a blade retraction assembly. When the top cover is on the pot body, it presses down on a pressing member, which drives a connecting member from a separated position to a driven position, thereby advancing the stirring blade. When the top cover is opened from the pot body, a first resetting member drives the connecting member from the driven position to a separated position, thereby retracting the stirring blade. With this structure, during the opening and closing of the top cover, the top cover acts as a driving source, driving the connecting member to move via the pressing member. This allows for simultaneous blade retraction and advance during the opening and closing process, eliminating the need to remove the top cover first and then manually advance and retract the stirring blade, simplifying the operation and improving the user experience.

[0008] Furthermore, when the pressing component is in the floating position, its upper end protrudes from the upper surface of the pot body. This facilitates pressing the pressing component downwards when the lid is closed, and the protruding component allows for easy operation when the user wants to press it by hand; and / or, the pot body has a mounting hole extending through its upper surface, into which the pressing component passes. Because the pressing component only moves up and down within the mounting hole, the lateral dimension of the mounting hole does not need to be too large, making it difficult for foreign objects to enter the pot body through the mounting hole.

[0009] Furthermore, the pressing component includes a button, with a pressing head at the upper end and a trigger part at the lower end. When the upper cover is placed on the pot body, the upper cover presses down on the pressing head, and the button, through the trigger part, drives the connecting component to move from the separated position to the driven position. By setting the pressing component as a button, it has the advantages of simple structure and low cost.

[0010] Furthermore, the triggering part is a trigger rib, and an inclined surface driving structure is provided between the trigger rib and the connecting member. The pressing member drives the connecting member to move through the inclined surface driving structure. The use of an inclined surface driving structure to achieve the driving connection between the pressing member and the connecting member has the advantages of simple transmission structure and reliable transmission.

[0011] Furthermore, the inclined surface drive structure includes a first inclined surface and a second inclined surface. The first inclined surface is located at the lower end of the trigger rib, and the second inclined surface is located at the upper end of the connector. The first and second inclined surfaces have the same inclination direction. The pressing component drives the connector to move through the cooperation of the first and second inclined surfaces. The cooperation of the first and second inclined surfaces can convert the vertical movement of the pressing component into the lateral movement of the connector, thereby realizing the tool advance and retraction operation.

[0012] Furthermore, the inclination angle of the first and second inclined planes on the horizontal plane is Q, where 30°≤Q≤80°. Setting the inclination angle Q within the above range makes it easier to press the pressing component, requiring less effort to operate, and does not require a large stroke or space, thus facilitating a reduction in assembly size.

[0013] Furthermore, the button has a guide notch on its side wall, and the pot body has a guide rib extending vertically and passing through the guide notch; and / or, the advance / retractor assembly also includes a second reset member, which is disposed between the pressing member and the pot body to reset the pressing member upwards. The lower end of the button has a mounting post, and the second reset member is a spring, which is sleeved on the mounting post, with its two ends abutting against the button and the pot body respectively. When the button moves up and down, the guide rib and guide notch work together to guide the button's movement, improving the stability of the button's movement. The mounting post provides assembly space for the spring, facilitating its fixation.

[0014] Furthermore, the connecting components include: a coupling movably sleeved on the drive shaft along its axial direction; a slider connected to the coupling; a first reset member disposed between the slider and the pot body; a pressing member driven by the slider; the pressing member driving the slider and the coupling to move; and the coupling being able to connect to or separate from the stirring blade. During the process of the upper cover being placed on the pot body, the upper cover presses down on the pressing member, which drives the slider and the coupling from a separated position to a driven position, thereby achieving the advance of the stirring blade; when the upper cover is opened from the pot body, the first reset member drives the slider and the coupling from the driven position to a separated position, thereby achieving the retraction of the stirring blade.

[0015] Furthermore, the stirring assembly also includes a third reset member. The coupling has a connecting hole extending axially along the drive shaft. One end of the drive shaft passes through the connecting hole, and the third reset member is located within the connecting hole. Both ends of the third reset member abut against the hole wall of the connecting hole and the drive shaft, respectively. A slider is sleeved on the outside of the coupling, and the slider is in a limiting fit with the side of the coupling facing the stirring blade. The side of the slider facing the stirring blade abuts against one end of the first reset member, and the other end of the first reset member abuts against the pot body. During the process of the upper cover being placed on the pot body, the upper cover presses down on the pressing member, which drives the slider to move. Under the action of the third reset member, the coupling also moves towards the stirring blade, thereby realizing the advance of the stirring blade. When the upper cover is opened from the pot body, the first reset member drives the slider to move away from the stirring blade, and the slider drives the coupling to move synchronously, thereby realizing the retraction of the stirring blade.

[0016] Furthermore, the pot body includes an outer shell and an inner pot. The inner pot is detachably mounted on the outer shell, and the stirring blade is rotatably mounted inside the inner pot. The outer shell can protect the inner pot. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0037] like Figures 1 to 12 As shown, this embodiment of the present invention provides a cooking appliance, which includes a pot body 10, a top cover 20, a stirring assembly 30, and a blade assembly 40. The top cover 20 is detachably mounted on top of the pot body 10. The stirring assembly 30 includes a stirring blade 31, a driving member 32, a connecting member 33, and a first resetting member 34. The stirring blade 31 is rotatably disposed within the pot body 10, and the connecting member 33 is movably disposed within the pot body 10. The connecting member 33 has a driving position for connecting the driving shaft 321 of the driving member 32 to the stirring blade 31 and a separating position for separating the driving shaft 321 from the stirring blade 31. The blade assembly 40 includes a pressing member 41, which is buoyantly disposed within the pot body 10. The pressing member 41 is drivenly connected to the connecting member 33 to move the connecting member 33. During the process of the upper cover 20 being placed on the pot body 10, the upper cover 20 presses down on the pressing member 41, and the pressing member 41 drives the connecting member 33 to move from the separated position to the driven position. When the upper cover 20 is opened by the pot body 10, the first reset member 34 drives the connecting member 33 to move from the driven position to the separated position.

[0038] Using the cooking appliance provided in this embodiment, when the upper cover 20 is placed on the pot body 10, the upper cover 20 presses down on the pressing member 41. The pressing member 41 drives the connecting member 33 from the separated position to the driven position, thereby realizing the advance of the stirring blade 31. When the upper cover 20 is opened from the pot body 10, the first reset member 34 drives the connecting member 33 from the driven position to the separated position, thereby realizing the retraction of the stirring blade 31. With the above structure, during the opening and closing of the upper cover 20, the upper cover 20 can act as a driving source and drive the connecting member 33 to move through the pressing member 41. Thus, the advance and retraction of the blade are realized simultaneously during the opening and closing of the cover, eliminating the need to remove the upper cover first and then manually complete the advance and retraction of the stirring blade. This simplifies the operation steps and improves the user experience.

[0039] like Figure 1 As shown, when the pressing member 41 is in the floating position, the upper end of the pressing member 41 protrudes from the upper surface of the pot body 10, which makes it easier for the lid 20 to press the pressing member 41 down when it is closed.

[0040] Furthermore, the protruding pressing part 41 facilitates operation when the user wants to press the pressing part 41 by hand.

[0041] Specifically, the pot body 10 has a mounting hole 11 extending through its upper surface, and the pressing member 41 passes through the mounting hole 11. Since the pressing member 41 only moves up and down within the mounting hole 11, the lateral dimension of the mounting hole 11 does not need to be too large, and foreign objects are less likely to enter the pot body 10 through the mounting hole 11.

[0042] like Figure 3 As shown, the pressing component 41 includes a button 411, with a pressing head at the upper end and a trigger part 412 at the lower end. During the process of the upper cover 20 covering the pot body 10, the upper cover 20 presses down on the pressing head, and the button 411 drives the connecting component 33 from the separated position to the driven position via the trigger part 412. By setting the pressing component 41 as a button 411, it has the advantages of simple structure and low cost.

[0043] In this embodiment, the trigger part 412 is a trigger rib 4121, and an inclined surface driving structure is provided between the trigger rib 4121 and the connecting member 33. The pressing member 41 drives the connecting member 33 to move through the inclined surface driving structure. The use of an inclined surface driving structure to realize the driving connection between the pressing member 41 and the connecting member 33 has the advantages of simple transmission structure and reliable transmission.

[0044] like Figure 3 and Figure 4 As shown, the inclined surface drive structure includes a first inclined surface 4122 and a second inclined surface 331. The first inclined surface 4122 is located at the lower end of the trigger rib 4121, and the second inclined surface 331 is located at the upper end of the connector 33. The first inclined surface 4122 and the second inclined surface 331 have the same inclination direction. The pressing member 41 drives the connector 33 to move through the cooperation of the first inclined surface 4122 and the second inclined surface 331. The cooperation of the first inclined surface 4122 and the second inclined surface 331 can convert the vertical movement of the pressing member 41 into the lateral movement of the connector 33, thereby realizing the advance and retraction operation.

[0045] The first inclined surface 4122 and the second inclined surface 331 have an inclination angle of Q on the horizontal plane, where 30°≤Q≤80°. Setting the inclination angle Q within the above range makes it easier to press the pressing part 41, reducing the effort required for operation and eliminating the need for a large stroke and space, thus facilitating a reduction in assembly size.

[0046] Specifically, the tilt angle Q can be 30°, 40°, 50°, 60°, 70°, 80°, and other values ​​between 30° and 80°.

[0047] In this embodiment, the inclination angle Q of the first inclined surface 4122 and the second inclined surface 331 on the horizontal plane is 45°.

[0048] like Figure 3 As shown, a guide notch 4111 is provided on the side wall of button 411, and a guide rib 12 is provided on the pot body 10. The guide rib 12 extends vertically and passes through the guide notch 4111. When button 411 floats up and down, the guide rib 12 and the guide notch 4111 cooperate to guide the movement of button 411, thereby improving the stability of button 411 when moving.

[0049] The advance and retraction blade assembly 40 also includes a second reset member 42, which is disposed between the pressing member 41 and the pot body 10 to reset the pressing member 41 upward.

[0050] In this embodiment, a mounting post 413 is provided at the lower end of the button 411, and the second reset member 42 is a spring. The spring is sleeved on the mounting post 413, and the two ends of the spring abut against the button 411 and the pot body 10, respectively. The mounting post 413 can provide assembly space for the spring, which facilitates the fixing of the spring.

[0051] like Figure 3 and Figure 7 As shown, the connecting member 33 includes a coupling 332 and a slider 333. The coupling 332 is movably sleeved on the drive shaft 321 along the axial direction of the drive shaft 321. The slider 333 is connected to the coupling 332. The first reset member 34 is disposed between the slider 333 and the pot body 10. The pressing member 41 is drivenly connected to the slider 333. The pressing member 41 can drive the slider 333 and the coupling 332 to move. The coupling 332 can be connected to or separated from the stirring blade 31.

[0052] During the process of the upper cover 20 being placed on the pot body 10, the upper cover 20 presses down on the pressing member 41, and the pressing member 41 drives the slider 333 and the coupling 332 to move from the separated position to the driven position, thereby realizing the advance of the stirring blade 31; when the upper cover 20 is opened from the pot body 10, the first reset member 34 drives the slider 333 and the coupling 332 to move from the driven position to the separated position, thereby realizing the retraction of the stirring blade 31.

[0053] Specifically, the slider 333 is fitted onto the coupling 332, which limits and guides the coupling 332, preventing it from wobbling, deforming, or becoming eccentric. The slider 333 is guided by the guide groove on the heat insulation cover of the pot body, ensuring smooth forward and backward movement.

[0054] It should be noted that the pressing member 41 drives the slider 333 and coupling 332 from the separated position to the driven position, including direct drive and indirect drive. Direct drive means that the pressing member 41 directly drives the slider 333 and coupling 332 to move. Indirect drive means that the pressing member 41 indirectly drives the slider 333 and coupling 332 to move. In this embodiment, the pressing member 41 indirectly drives the slider 333 and coupling 332 to move.

[0055] Specifically, the stirring assembly 30 also includes a third reset member 35. The coupling 332 has a connecting hole 3321 extending axially along the drive shaft 321. One end of the drive shaft 321 passes through the connecting hole 3321. The third reset member 35 is located inside the connecting hole 3321, and both ends of the third reset member 35 abut against the hole wall of the connecting hole 3321 and the drive shaft 321, respectively. The slider 333 is sleeved on the outside of the coupling 332. The slider 333 is in a limiting fit with the side of the coupling 332 facing the stirring blade 31. The side of the slider 333 facing the stirring blade 31 abuts against one end of the first reset member 34, and the other end of the first reset member 34 abuts against the pot body 10.

[0056] During the process of the upper cover 20 being placed on the pot body 10, the upper cover 20 presses down on the pressing member 41, the pressing member 41 drives the slider 333 to move, and the coupling 332 also moves toward the direction closer to the stirring blade 31 under the action of the third reset member 35, thereby realizing the advance of the stirring blade 31; when the upper cover 20 is opened from the pot body 10, the first reset member 34 drives the slider 333 to move away from the stirring blade 31, and the slider 333 drives the coupling 332 to move synchronously, thereby realizing the retraction of the stirring blade 31.

[0057] Both the first reset member 34 and the third reset member 35 are springs.

[0058] like Figure 1 As shown, the pot body 10 includes an outer shell 13 and an inner pot 14. The inner pot 14 is detachably disposed on the outer shell 13, and the stirring blade 31 is rotatably disposed inside the inner pot 14. The outer shell 13 can protect the inner pot 14.

[0059] In this embodiment, the pressing component 41 is an integral injection molded structure, and the slider 333 is an integral injection molded structure.

[0060] To make it easier to understand, the following explanation will use specific examples of cooking utensils:

[0061] Opening the lid and retracting the blade: The upper lid 20 is fixed by the hinge of the pot body 10 and flips back around the rotation axis. The bottom of the outer lid of the upper lid 20 is no longer pressed against the button 411 of the pot body 10. The button 411 loses the downward pressing force. Under the action of the second reset member 42, the button 411 resets upward. The slider 333 moves backward under the action of the first reset member 34. The slider 333 pushes the gear (coupling 332) backward at the same time. At the same time, the slider 333 moves backward, so that the gear moves backward and disengages from the tooth sleeve on the stirring blade 31. Because it is not engaged, the inner pot 14 can be directly removed from the outer shell 13.

[0062] Simultaneous closing of the lid and advance of the blade: The upper lid 20 is fixed by the hinge of the pot body 10 and flips back around the rotation axis. The bottom of the outer lid of the upper lid 20 presses against the button 411 of the pot body 10. The button 411 moves downward under the downward pressing force. The lower inclined surface (first inclined surface 4122) of the button 411 presses down on the second inclined surface 331 of the slider 333. The slider 333 moves forward, and the gear also moves forward, so that the gear moves forward and meshes with the gear sleeve. Because of the meshing, the stirring blade 31 will rotate with the rotation of the motor and the gear.

[0063] Cooking appliances include, but are not limited to, stir-fry machines and multi-functional pots with stir-frying functions.
