Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and particularly to a key assembly and a cooking appliance having the same. Background Art

[0002] Existing household appliances such as cooking appliances include a housing and a cover body fastened to the housing, and a lock for connecting the cover body and the housing is controlled by an opening button assembly. Taking an electric rice cooker as an example, during the use of the electric rice cooker by a user, it is found that there is a problem of poor opening of the electric rice cooker during use, that is, the electric rice cooker does not open the cover after the user presses the opening button. Summary of the Utility Model

[0003] In view of this, the present application provides a key assembly and a cooking appliance having the same, so as to solve the technical problem that the key assembly in the prior art is easily driven by the housing to shift and cause the key assembly to fail.

[0004] In a first aspect, the present application provides a key assembly. The key assembly is installed on a housing assembly of a cooking appliance. The housing assembly includes a housing having an opening and a support ring sleeved at the opening of the housing. The key assembly includes: a key; a support frame installed at a position of the housing close to the support ring, and an activity space for the key is formed inside the support frame; a limiting structure, the support frame and / or the support ring are provided with a limiting structure, and when the support frame is assembled to the support ring, the support ring restricts the support frame from shifting in the direction of the housing through the limiting structure.

[0005] Beneficial Effect: The key assembly proposed in the present application is installed on the housing of the cooking appliance and is limited to the support ring of the cooking appliance through the limiting structure, thereby reducing the phenomenon that the housing of the cooking appliance deforms and drives the key assembly to shift, and improving the assembly stability and use reliability of the key assembly.

[0006] Specifically, the support ring limits the key assembly through the limiting structure. Therefore, even if the housing of the cooking appliance has an outward convex deformation phenomenon, the housing will not drive the key assembly to move outward, resulting in an increase in the distance between the key assembly and the lock assembly.

[0007] In an optional embodiment, the limiting structure includes a limiting plate disposed on the outer sidewall of the support frame, and the limiting plate is integrally formed with the support frame.

[0008] Beneficial Effect: The limiting plate has a small thickness and a simple structure, and can extend into the narrow space at the support frame, which can not only achieve the purpose of forming a limiting fit with the support frame, but also reduce the installation difficulty of the limiting plate and reduce the interference phenomenon between the limiting plate and other components in the cooking appliance.

[0009] In an alternative embodiment, the support frame is further provided with reinforcing ribs, which are arranged on the side of the limiting plate facing away from the support ring.

[0010] Advantageous effects: The reinforcing ribs are arranged on the side of the limiting plate facing away from the support ring, thereby reducing the influence of the reinforcing ribs on the limiting fit between the limiting plate and the support ring, so that the limiting plate can fit against the outer side wall of the support ring, or there is an effective gap between the limiting plate and the outer side wall of the support ring. By forming an effective gap between the limiting plate and the outer side wall of the support ring, not only can the assembly efficiency of the limiting plate be improved, and the interference phenomenon between the limiting plate and the support ring during the assembly process be reduced, but also the limiting plate can move at this effective gap, so that the key assembly will not be displaced to a position outside the effective pressing stroke.

[0011] In an alternative embodiment, the limiting structure includes a telescopic tongue arranged on the outer side wall of the support frame, and the telescopic tongue is arranged to be telescopic along the installation direction perpendicular to the support frame.

[0012] Advantageous effects: When the key assembly is installed in the key hole of the housing of the cooking appliance, in order to enable the telescopic tongue of the key assembly to be clamped to the support ring inside the key hole in the natural state, the protruding dimension of the telescopic tongue in the natural state needs to be greater than the size of the key hole. At this time, in order to enable the telescopic tongue of the key assembly to smoothly pass through the key hole, the embodiment of the present application proposes that the telescopic tongue can be in a contracted state under an external force, so that the telescopic tongue is in a contracted state under the pushing force of the key hole and the support ring during the process of passing through the key hole, and then can be in an extended natural state after passing through the key hole and reaching the side wall of the support ring, so that the telescopic tongue of the key assembly can be clamped on the side wall of the support ring.

[0013] In an alternative embodiment, the telescopic tongue includes a receiving groove, a tongue body and an elastic element. The receiving groove is arranged on the outer side wall of the support frame and is distributed along the installation direction perpendicular to the support frame, and the tongue body is installed in the receiving groove through the elastic element.

[0014] Advantageous effects: When the telescopic tongue is under the pushing force of the key hole and the support ring during the process of passing through the key hole, the pushing force of the key hole and the support ring on the tongue body overcomes the elastic force of the elastic element and is in a contracted state inside the receiving groove. When the telescopic tongue passes through the key hole and reaches the side wall of the support ring, the elastic element pushes the tongue body out of the receiving groove and into an extended natural state through its own elastic force, so that the telescopic tongue of the key assembly can be clamped on the side wall of the support ring.

[0015] In an alternative embodiment, the support frame is arranged as a basin structure. The interior of the basin structure forms a moving space for the key, and a through hole for the key to stretch is formed at the bottom of the basin structure. The limiting structure is arranged on the outer side wall of the basin structure and close to the bottom of the basin structure.

[0016] Beneficial effects: The support frame is set as a basin structure. An activity space for wrapping the button is formed inside the basin structure, and an assembly structure for cooperating with the outer shell is formed outside the basin structure, which can not only protect the button but also play a role in stably assembling the button assembly.

[0017] In a second aspect, the present application provides a cooking appliance, which includes a housing assembly having an opening, a cover body covering the opening of the housing assembly, and a locking component for locking the housing assembly and the cover body. The cooking appliance further includes a button assembly according to the first aspect of the present application. The button assembly is arranged at a position corresponding to the locking component of the housing assembly and is used to drive the locking component to open.

[0018] Beneficial effects: The button assembly proposed in the present application is embedded in the outer shell of the cooking appliance and is limited to the support frame of the cooking appliance through a limiting structure, thereby reducing the phenomenon that the displacement of the button assembly is driven by the deformation of the outer shell of the cooking appliance, and improving the assembly stability and use reliability of the button assembly.

[0019] In an optional implementation manner, the housing assembly includes an outer shell having an opening and a support ring sleeved at the opening of the outer shell. The limiting structure of the button assembly cooperates with the inner wall of the support ring facing away from the outer shell, and an idle stroke gap is formed between the button assembly and the locking component.

[0020] Beneficial effects: By limiting the limiting structure of the button assembly through the inner wall of the support ring, an assembly space can be provided for the limiting structure, thereby reducing the interference phenomenon between the limiting structure and the locking component. The avoidance groove can also form an idle stroke gap L between the button assembly and the locking component. During the use of the button assembly, when the user occasionally presses the button assembly, the button assembly will not trigger the locking component. When the user continuously presses the button assembly, the button assembly moves to the stroke gap before triggering the button assembly, thereby reducing the phenomenon that the button assembly accidentally triggers and opens the locking component.

[0021] In an optional implementation manner, the locking component is set to be rotatable in the direction of the inner wall of the support ring. When the locking component rotates to a state close to the inner wall of the support ring, a safety gap is provided between the limiting structure and the locking component.

[0022] Beneficial effects: By providing a safety gap between the limiting structure and the locking component, the normal rotation of the locking component can be ensured without being affected by the limiting structure, so that the locking component can rotate towards the inner wall of the support ring to the position for opening the cover body.

[0023] In an optional implementation manner, the cooking appliance includes a rice cooker. Description of the Drawings

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the protection scope of this application.

For example, it can be fixedly connected, detachably connected, or integrally connected; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediate medium, and can also be the connection inside two elements. It can be wirelessly connected or wired connected. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0042] Regarding the phenomenon of poor lid opening during the use of cooking appliances such as rice cookers, through analysis, it is known that the outer shell of cooking appliances such as rice cookers is generally a sheet metal part that is prone to deformation. The lid opening button assembly is fixed on the sheet metal outer shell, and the lock catch is installed at a position inside the cooking appliance corresponding to the lid opening button assembly. At this time, if the sheet metal outer shell bulges and deforms during use, it will drive the lid opening button assembly to move outward, increasing the distance between the lid opening button assembly and the lock catch. At this time, when the lid opening button is pressed, the effective stroke of the lid opening button is not enough to reach the position where the lock catch can be effectively unlocked, resulting in the problem that the cooking appliance cannot be opened smoothly.

[0043] To solve the problem of poor lid opening that occurs during the use of existing cooking appliances such as rice cookers, the embodiments of this application propose a button assembly. The following combines Figures 1 to 8 , to describe the embodiments of this application.

[0044] As Figures 1 to 5As shown, according to an embodiment of the present application, on the one hand, the present application provides a key assembly 30. The key assembly 30 is installed on the housing assembly 10 of the cooking appliance 100. The housing assembly 10 includes a housing 11 with an opening and a support ring 12 sleeved at the opening of the housing 11. The key assembly 30 includes a key 31, a support frame 32, and a limiting structure 321. The support frame 32 is installed at a position of the housing 11 close to the support ring 12. An activity space for the key 31 is formed inside the support frame 32. The support frame 32 and / or the support ring 12 is provided with the limiting structure 321. When the support frame 32 is assembled to the support ring 12, the support ring 12 restricts the support frame 32 from shifting in the direction of the housing 11 through the limiting structure 321.

[0045] In this embodiment, the key assembly 30 proposed in the embodiment of the present application is installed on the housing 11 of the cooking appliance 100 and is limited to the support ring 12 of the cooking appliance 100 through the limiting structure 321, thereby reducing the phenomenon that the housing 11 of the cooking appliance 100 deforms and drives the key assembly 30 to shift, and improving the assembly stability and use reliability of the key assembly 30.

[0046] Specifically, the key assembly 30 is installed on the housing 11 of the cooking appliance 100 and is used to drive the unlocking or locking of the lock assembly 40 inside the cooking appliance 100. The lock assembly 40 includes a lower lock hook 41 installed on the housing assembly 10 and an upper lock hook 42 installed on the cover body 20. The lower lock hook 41 is assembled on the support ring 12 of the housing assembly 10 through shaft-hole fit, and the lower lock hook 41 can rotate around the shaft. As Figure 3 , when the key assembly 30 is not pressed, the distance between the lower lock hook 41 and the lower lock hook 41 is the dead travel. As Figure 5 , when the key assembly 30 is pressed, the key assembly 30 pushes the lower lock hook 41 to rotate around the shaft, so that the lower lock hook 41 is disengaged from the upper lock hook 42, and then the cover body 20 can be opened smoothly.

[0047] The support ring 12 proposed in the embodiment of the present application limits the key assembly 30 through the limiting structure 321. Therefore, even if the housing 11 of the housing assembly 10 bulges and deforms, the housing 11 will not drive the key assembly 30 to move outward, resulting in an increase in the distance between the key assembly 30 and the lower lock hook 41.

[0048] Furthermore, the embodiment of the present application proposes to limit the key assembly 30 through the support ring 12 and the limiting structure 321, reducing the phenomenon that the key assembly 30 bulges outward due to secondary deformation caused by bumping and squeezing of the housing 11 during production, assembly, transportation, and user use.

[0049] It should be noted that the specific positions and structures of the support frame 32 and the limiting structure 321 are not limited in the embodiments of the present application because the main improvement point of the present application is that the button assembly 30 can be limited on the support ring 12 through the limiting structure 321, so as to reduce the technical effect that the button assembly 30 is driven by the housing 11 to shift. As for the specific positions and structures of the support frame 32 and the limiting structure 321, they can be set according to the type of the button assembly 30 and the actual use environment. For example, the support frame 32 can be set to a rectangular or circular structure, etc. The limiting structure 321 can be set on the support frame 32, or on the support ring 12, or limiting structures 321 can be provided on both the support frame 32 and the support ring 12. The limiting structure 321 can be set to a limiting plate, a limiting groove or a telescopic tongue, etc. These adjustments all belong to the protection scope of the embodiments of the present application.

[0050] The following Figures 1 to 8 embodiments are used to elaborate on the preferred embodiments of the specific structures of the support frame 32 and the limiting structure 321.

[0051] As Figures 6 to 8 shown, in some embodiments, the limiting structure 321 includes a limiting plate provided on the outer side wall of the support frame 32, and the limiting plate is provided to be integrally formed with the support frame 32.

[0052] In the above embodiments, the limiting plate has a small thickness and a simple structure, and can extend into the narrow space at the support frame 32, which can not only achieve the purpose of forming a limiting fit with the support frame 32, but also reduce the installation difficulty of the limiting plate and reduce the interference phenomenon between the limiting plate and other components in the cooking appliance 100.

[0053] Specifically, in the embodiments of the present application, the distance between the button assembly 30 and the support ring 12 is restricted by the limiting plate on the support frame 32, especially the distance between the button assembly 30 and the support ring 12 cannot be too large, so as to ensure that the button assembly 30 has a certain effective stroke, and the pressing action of the button assembly 30 will not fail due to the too large distance between the button assembly 30 and the support ring 12.

[0054] Specifically, the button assembly 30 is used to drive the lock assembly 40 inside the cooking appliance 100 to rotate and unlock. In order to prevent the lock assembly 40 from interfering with the limiting plate during the process of rotating and unlocking, the embodiments of the present application propose that the thickness of the limiting plate needs to be less than the gap between the lock assembly 40 and the support ring 12 after rotation, and a gap of 1 mm is reserved between the lock assembly 40 and the limiting plate after rotation.

[0055] As Figures 6 to 8 shown, in some embodiments, the support frame 32 is further provided with a reinforcing rib 322, and the reinforcing rib 322 is provided on the side of the limiting plate facing away from the support ring 12.

[0056] In this embodiment, in order to prevent the limiting plate from deforming under external force and causing the failure of the limiting function, the embodiment of the present application also proposes to provide a reinforcing rib 322 on the support frame 32 to improve the structural strength of the limiting plate through the reinforcing rib 322.

[0057] Furthermore, the reinforcing rib 322 is arranged on the side of the limiting plate facing away from the support ring 12, so as to reduce the influence of the reinforcing rib 322 on the limiting fit between the limiting plate and the support ring 12, so that the limiting plate can fit to the outer side wall of the support ring 12, or there is an effective gap between the limiting plate and the outer side wall of the support ring 12. By forming an effective gap between the limiting plate and the outer side wall of the support ring 12, not only can the assembly efficiency of the limiting plate be improved, and the interference phenomenon between the limiting plate and the support ring 12 during the assembly process be reduced, but also the limiting plate can move at this effective gap, so that the key assembly 30 will not be offset to a position where it is out of the effective pressing stroke.

[0058] In some embodiments, the limiting structure 321 includes a telescopic tongue arranged on the outer side wall of the support frame 32, and the telescopic tongue is arranged to be telescopic along the installation direction perpendicular to the support frame 32.

[0059] In the above embodiment, the key assembly 30 is installed in the key 31 hole of the housing 11 of the cooking appliance 100. In order to enable the telescopic tongue of the key assembly 30 to be clamped to the support ring 12 inside the key 31 hole in the natural state, the protruding dimension of the telescopic tongue in the natural state needs to be greater than the dimension of the key 31 hole. At this time, in order to enable the telescopic tongue of the key assembly 30 to smoothly pass through the key 31 hole, the embodiment of the present application proposes that the telescopic tongue can be in a contracted state after bearing an external force, so that the telescopic tongue is in a contracted state under the pushing force of the key 31 hole and the support ring 12 during the process of passing through the key 31 hole, and then can be in an extended natural state after passing through the key 31 hole and reaching the side wall of the support ring 12, so that the telescopic tongue of the key assembly 30 can be clamped on the side wall of the support ring 12.

[0060] In some embodiments, the telescopic tongue includes a receiving groove, a tongue body and an elastic element. The receiving groove is arranged on the outer side wall of the support frame 32 and is distributed along the installation direction perpendicular to the support frame 32, and the tongue body is installed in the receiving groove through the elastic element.

[0061] In the above embodiment, when the telescopic tongue is under the pushing force of the key 31 hole and the support ring 12 during the process of passing through the key 31 hole, the pushing force of the key 31 hole and the support ring 12 on the tongue body overcomes the elastic force of the elastic element and is in a contracted state inside the receiving groove. When the telescopic tongue passes through the key 31 hole and reaches the side wall of the support ring 12, the elastic element pushes the tongue body out of the receiving groove through its own elastic force and is in an extended natural state, so that the telescopic tongue of the key assembly 30 can be clamped on the side wall of the support ring 12.

[0062] As Figures 6 to 8 shown, in some embodiments, the support frame 32 is further provided with a clamping structure 323, and the clamping structure 323 is disposed on the outer sidewall of the support frame 32 and can be clamped to the inner wall of the housing 11.

[0063] In this embodiment, the button assembly 30 is installed in the button 31 hole of the housing 11 of the cooking appliance 100. In order to enable the support frame 32 of the button assembly 30 to be clamped to the inner sidewall of the button 31 hole, the embodiment of the present application proposes to provide a clamping structure 323 on the support frame 32 that can be connected to the inner sidewall of the button 31 hole. When the clamping structure 323 passes through the button 31 hole, it presses the button 31 hole to deform, and then passes through the button 31 hole to reach the inner sidewall of the button 31 hole and is clamped to the inner sidewall of the button 31 hole, thereby improving the assembly stability of the button assembly 30 on the housing 11 and reducing the phenomenon that the button assembly 30 shakes on the housing 11 or shifts inwardly into the cooking appliance 100.

[0064] Specifically, the clamping structure 323 includes a protrusion disposed on the outer sidewall of the support frame 32, and a guiding inclined surface is provided on the side of the protrusion facing the housing 11, so that the protrusion can smoothly pass through the button 31 hole on the housing 11 through the guiding inclined surface.

[0065] As Figures 6 to 8 shown, in some embodiments, the support frame 32 is further provided with a flanging structure, and the flanging structure is disposed on the edge of the support frame 32 and can be pressed against the outer wall of the housing 11.

[0066] In this embodiment, after the button assembly 30 is assembled into the button 31 hole of the housing 11 of the cooking appliance 100, the flanging structure of the support frame 32 of the button assembly 30 is pressed against the periphery of the button 31 hole, thereby playing a limiting role on the button assembly 30 and reducing the phenomenon that the button assembly 30 slides inwardly into the cooking appliance 100 and falls off during use. In addition, the flanging structure of the support frame 32 can also play a role in sealing the gap between the button assembly 30 and the button 31 hole, reducing the phenomenon that external dust and moisture enter the interior of the cooking appliance 100 through the button 31 hole.

[0067] As Figures 6 to 8 shown, in some embodiments, the support frame 32 is configured as a basin structure, an activity space for the button 31 is formed inside the basin structure, a through hole for the button 31 to extend and contract is formed at the bottom of the basin structure, and the limiting structure 321 is disposed on the outer sidewall of the basin structure and near the bottom of the basin structure.

[0068] In this embodiment, the support frame 32 is arranged in a basin structure. An activity space for wrapping the button 31 is formed inside the basin structure, and an assembly structure for cooperating with the outer shell 11 is formed outside the basin structure, which can not only protect the button 31 but also play a role in stably assembling the button assembly 30.

[0069] As Figures 1 to 8 shown, in a second aspect, the present application provides a cooking appliance 100. The cooking appliance 100 includes a housing assembly 10 having an opening, a lid 20 covering the opening of the housing assembly 10, and a locking component 40 for locking the housing assembly 10 and the lid 20. The cooking appliance 100 further includes a button assembly 30 according to the first aspect of the present application. The button assembly 30 is arranged at a position corresponding to the locking component 40 of the housing assembly 10 and is used to drive the locking component 40 to open.

[0070] In this embodiment, the button assembly 30 proposed in the present application is embedded in the outer shell 11 of the cooking appliance 100 and is limited to the support frame 32 of the cooking appliance 100 through a limiting structure 321, thereby reducing the phenomenon that the displacement of the button assembly 30 is driven by the deformation of the outer shell 11 of the cooking appliance 100, and improving the assembly stability and use reliability of the button assembly 30.

[0071] Specifically, the process of opening the lid of the cooking appliance 100 is as follows: after the user presses the button assembly 30, the button assembly 30 pushes the lower locking hook 41 of the locking component 40 assembled on the housing assembly 10 to rotate, so that the lower locking hook 41 on the housing assembly 10 is disengaged from the upper locking hook 42 of the locking component 40 assembled on the lid 20, and then the lid 20 can be automatically opened under the action of the torsion spring.

[0072] As Figures 1 to 8 shown, in some embodiments, the housing assembly 10 includes an outer shell 11 having an opening and a support ring 12 sleeved at the opening of the outer shell 11. The limiting structure 321 of the button assembly 30 cooperates with the inner wall 121 of the support ring 12 facing away from the outer shell 11, and an idle stroke gap L is formed between the button assembly 30 and the locking component 40.

[0073] In this embodiment, by limiting the limiting structure 321 of the button assembly 30 through the inner wall 121 of the support ring 12, an idle stroke gap L can be formed between the button assembly 30 and the locking component 40. During the use of the button assembly 30, when the user occasionally presses the button assembly 30, the button assembly 30 will not trigger the locking component 40. When the user continuously presses the button assembly 30, the button assembly 30 moves to the stroke gap before triggering the button assembly 30, thereby reducing the phenomenon that the button assembly 30 accidentally triggers and opens the locking component 40.

[0074] As Figure 5As shown, in an alternative embodiment, the latch assembly 40 is configured to be rotatable towards the inner wall 121 of the support ring 12. When the latch assembly 40 rotates to a state close to the inner wall 121 of the support ring 12, there is a safety gap between the limiting structure 321 and the latch assembly 40.

[0075] In this embodiment, by providing a safety gap between the limiting structure 321 and the latch assembly 40, the normal rotation of the latch assembly 40 can be ensured without being affected by the limiting structure 321, so that the latch assembly 40 can rotate towards the inner wall of the support ring 12 to the position where the cover body 20 is opened.

[0076] Specifically, the latch assembly 40 includes a lower latch hook 41 installed on the support ring 12 of the housing assembly 10, and an upper latch hook 42 installed on the cover body 20. The lower latch hook 41 is assembled on the support ring 12 of the housing assembly 10 through shaft-hole fit, and the lower latch hook 41 can rotate around the shaft. As Figure 3 shown, when the button assembly 30 is not pressed, the distance between the lower latch hooks 41 is the dead travel. As Figure 5 shown, when the button assembly 30 is pressed, the button assembly 30 pushes the lower latch hook 41 to rotate around the shaft, so that the lower latch hook 41 is disengaged from the upper latch hook 42, and then the cover body 20 can be opened smoothly.

[0077] Taking the limiting structure 321 as a limiting plate as an example, the thickness of the limiting plate is set according to the use space, and the safety gap between the lower latch hook 41 and the limiting plate when the lower latch hook 41 rotates to the position of opening the upper latch hook 42 can be 1 mm, so as to prevent the lower latch hook 41 from interfering with the limiting plate during the process of rotating and unlocking.

[0078] It should be noted that the embodiments of the present application do not limit the specific products of the cooking appliance 100, because the cooking appliance 100 includes various products using the button assembly 30 of the embodiments of the present application, such as rice cookers, pressure cookers, and steam cookers.

[0079] In an alternative embodiment, the cooking appliance 100 includes a rice cooker.

[0080] Although the embodiments of the present application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations fall within the scope defined by the appended claims.
