Description

Technical Field

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

[0002] When cooking food using cooking appliances, the lid assembly can become contaminated by oil fumes, heat, and splattered food. Related technologies describe lid assemblies that include a transmission structure, a lid mounted on the transmission structure, and a nozzle mounted on and installed on the lid. The lid has an open position and a closed position. The transmission structure allows the lid to switch between these positions. When the lid is in the closed position, the nozzle sprays cleaning fluid to remove contaminants from the lid.

[0003] However, since the cover is installed on the transmission structure for a long time, dust easily accumulates at the installation position between the cover and the transmission structure, creating cleaning dead spots and making cleaning incomplete. Utility Model Content

[0004] The main purpose of this utility model is to provide a lid assembly and cooking utensil to solve the problem of cleaning dead corners in the installation position between the lid and the transmission structure in related technologies, which leads to incomplete cleaning.

[0005] To achieve the above objectives, according to one aspect of the present invention, a cover assembly is provided, comprising: a cover having an open position and a closed position; a nozzle disposed on the cover; and a transmission structure detachably connected to the cover, wherein when the cover is connected to the transmission structure, the transmission structure can drive the cover to switch between the open position and the closed position.

[0006] By applying the technical solution of this utility model, when it is necessary to clean the installation position between the cover and the transmission structure, the cover and the transmission structure can be disassembled, exposing the installation position to the outside, avoiding cleaning dead corners, and facilitating a more thorough cleaning of the installation position. Therefore, the technical solution of this application effectively solves the problem in related technologies where there are cleaning dead corners at the installation position between the cover and the transmission structure, resulting in incomplete cleaning.

[0007] Furthermore, the transmission structure is detachably connected to the cover via a plug-in mechanism. This plug-in mechanism allows for easy assembly and disassembly of the transmission structure and the cover without the need for additional tools. This means that when cleaning the area between the cover and the transmission structure is required, users can easily separate them to thoroughly clean any hard-to-reach areas, improving cleaning efficiency.

[0008] Furthermore, the plug-in structure includes a socket and a pluggable tube within the socket. One of the socket and the tube is located on the cover, while the other is located on the transmission structure. The nozzle communicates with the tube. Through the cooperation of the socket and the tube, the cover can be stably connected to the transmission structure, which simplifies the nozzle installation process, ensures smooth delivery of cleaning fluid, and allows for quick disconnection during disassembly.

[0009] Furthermore, when the insert is mounted on the transmission structure, the cover includes a cover plate and a sealing part passing through the cover plate. The insert hole is located on the sealing part, and the nozzle is located on the sealing part. By placing the insert hole and nozzle on the sealing part, it is ensured that the connection between the nozzle and the transmission structure maintains good sealing during the opening and closing of the cover, preventing steam, fumes, or food splashes from entering the transmission structure during cooking, thereby avoiding contamination and damage to the transmission structure.

[0010] Furthermore, the transmission structure includes a transmission arm and a pipe connector portion mounted on the transmission arm. An insert tube is positioned on the pipe connector portion, and the interior of the insert tube communicates with the interior of the pipe connector portion. Placing the insert tube on the pipe connector portion makes the delivery path of the cleaning fluid more direct and unobstructed, improving the efficiency of fluid transmission. This design also simplifies the connection between the transmission structure and the nozzle, reduces the risk of fluid leakage, and improves the reliability of the cleaning process.

[0011] Furthermore, the outer wall of the insertion tube is provided with a snap-fit ​​protrusion. The insertion hole includes a first section and a second section connected together. The second section has an enlarged diameter section, the maximum radial dimension of which is greater than that of the first section. The snap-fit ​​protrusion snaps into the enlarged diameter section. The cooperation between the snap-fit ​​protrusion and the enlarged diameter section provides stable support and positioning for the insertion tube, preventing accidental loosening or detachment during cooking or cleaning, and ensuring the normal operation of cooking and cleaning functions. At the same time, this design also allows for quick release of the insertion tube during disassembly, improving the convenience of disassembly and assembly.

[0012] Furthermore, the insertion port also includes a third section communicating with the second section. The first, second, and third sections are sequentially arranged along the axis of the insertion port. The second section also has a guide ramp and a limiting ramp. The guide ramp connects the expansion section and the first section, and the limiting ramp connects the expansion section and the third section. The locking protrusion engages with the guide ramp and then with the limiting ramp to stop, so that the locking protrusion engages at the expansion section. The nozzle is detachably mounted in the third section. The guide ramp and the limiting ramp further optimize the insertion and removal process of the tube and reduce the difficulty of operation. The guide ramp helps the locking protrusion smoothly enter the expansion section, while the limiting ramp ensures the correct positioning of the tube, preventing over-insertion or incomplete insertion, and ensuring a stable connection between the nozzle and the tube. At the same time, the detachable mounting of the nozzle in the third section enhances the ease of cleaning and replacement flexibility of the nozzle.

[0013] Furthermore, when the insert is mounted on the cover, the transmission structure includes a transmission arm and a pipe connector mounted on the transmission arm, with the insertion hole located on the pipe connector. When the insert is fixed to the cover, this configuration makes the nozzle connection point more stable, reduces the impact on the nozzle connection point during cover movement, protects the nozzle and its internal delivery pipes, and reduces maintenance costs.

[0014] Furthermore, the cover includes a cover plate and a connecting tube socket connected to the cover. The connecting tube socket is connected to the insertion tube, and the nozzle is detachably suspended on the connecting tube socket, with the interior of the nozzle communicating with the connecting tube socket. Designing the nozzle to be detachably suspended on the connecting tube socket increases the ease of maintenance. When cleaning is required, the detachability of the nozzle allows users to directly disassemble and clean it, avoiding cleaning dead zones. The communication between the interior of the nozzle and the connecting tube socket ensures that the cleaning fluid can be accurately delivered to the nozzle, while also facilitating nozzle replacement and cleaning.

[0015] According to another aspect of the present invention, a cooking appliance is provided, including a base and a cover assembly disposed on the base, wherein the cover assembly is the cover assembly described above. The cooking appliance also includes a motor disposed on the base, wherein the motor is capable of driving the transmission structure to move. Attached Figure Description

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0034] This application provides a cover assembly, such as Figures 1 to 4 As shown, one embodiment of the cover assembly includes a cover 10, a nozzle 30, and a transmission structure 61. The cover 10 has an open position and a closed position. The nozzle 30 is disposed on the cover 10. The transmission structure 61 is detachably connected to the cover 10, and when the cover 10 is connected to the transmission structure 61, the transmission structure 61 can drive the cover 10 to switch between the open position and the closed position.

[0035] The technical solution of Embodiment 1 of the cover assembly allows for the disassembly of the cover 10 and transmission structure 61 when cleaning is required at the installation location between them. This exposes the installation location, preventing cleaning dead zones and facilitating thorough cleaning. Therefore, Embodiment 1 of the cover assembly effectively solves the problem of incomplete cleaning due to cleaning dead zones at the installation location between the cover and transmission structure in related technologies. The nozzle 30 sprays cleaning fluid to clean the cover 10. The nozzle 30 is a water-driven rotary nozzle, facilitating the spraying of cleaning fluid using a water-driven rotary principle.

[0036] like Figures 1 to 4 As shown, the transmission structure 61 is detachably connected to the cover 10 via a plug-in structure 50. The plug-in structure 50 allows for easy assembly and disassembly of the transmission structure 61 and the cover 10 without the need for additional tools. This means that when cleaning the mounting area between the cover 10 and the transmission structure 61 is required, the user can easily separate them to thoroughly clean any potential hard-to-reach areas, thus improving cleaning efficiency.

[0037] like Figures 1 to 4As shown, the plug-in structure 50 includes a socket 51 and a pluggable tube 52 that can be inserted into the socket 51. The socket 51 is located on the cover 10, and the tube 52 is located on the transmission structure 61. The nozzle 30 communicates with the tube 52. Through the cooperation of the socket 51 and the tube 52, the cover 10 can be stably connected to the transmission structure 61, which also simplifies the installation steps of the nozzle 30, ensures the smooth delivery of cleaning fluid, and allows for quick disconnection during disassembly.

[0038] In other embodiments, the insertion hole 51 is provided on the cover 10, and the insertion tube 52 is provided on the transmission structure 61.

[0039] like Figures 1 to 4 As shown, when the insertion tube 52 is installed on the transmission structure 61, the cover 10 includes a cover plate 11 and a sealing part 12 passing through the cover plate 11. The insertion hole 51 is installed on the sealing part 12, and the nozzle 30 is installed on the sealing part 12. Installing the insertion hole 51 and the nozzle 30 on the sealing part 12 ensures a good seal between the nozzle 30 and the transmission structure 61 during the opening and closing of the cover 10, preventing steam, fumes, or food splashes from entering the transmission structure 61 during cooking, thus avoiding contamination and damage to the transmission structure 61. The sealing part 12 is preferably a sealing gasket.

[0040] like Figures 1 to 4 As shown, the transmission structure 61 includes a transmission arm 611 and a pipe connector portion 612 disposed on the transmission arm 611. An insert tube 52 is disposed on the pipe connector portion 612, and the interior of the insert tube 52 communicates with the interior of the pipe connector portion 612. Placing the insert tube 52 on the pipe connector portion 612 makes the delivery path of the cleaning fluid more direct and unobstructed, improving the efficiency of fluid transmission. This design also simplifies the connection between the transmission structure 61 and the nozzle 30, reduces the risk of fluid leakage, and improves the reliability of the cleaning process.

[0041] Specifically, a liquid delivery pipe 62 communicating with the pipe joint portion 612 is provided inside the transmission arm 611.

[0042] Specifically, the pipe fitting 612 and the transmission arm 611 are integrally formed structures, while the pipe fitting is a separate structure from the liquid delivery pipe.

[0043] The transmission arm 611 includes an arm seat connected to the cover 10 and an arm cover placed on the arm seat. The arm seat is a plastic part, mainly serving a supporting and containing function; the arm seat has a U-shaped cavity, which mainly accommodates the liquid delivery pipe so that cleaning fluid, such as water, can flow through the liquid delivery pipe; the arm cover is also a plastic part, mainly forming a seal with the arm seat to facilitate the containment of the liquid delivery pipe while keeping the liquid delivery pipe hidden for aesthetic purposes; the cover is a transparent element, which can be made of glass, highly transparent plastic, or a transparent metallic material, indium tin oxide (ITO). The cover is mainly used to facilitate real-time monitoring of the cooking process; during the cleaning process, it mainly prevents water vapor from splashing out of the cover; the liquid delivery pipe is a food-grade vapor-phase silicone tube, mainly guiding the cleaning fluid drawn by the water pump to the nozzle.

[0044] like Figures 1 to 4 As shown, the outer wall of the insertion tube 52 is provided with a snap-fit ​​protrusion 521, and the insertion hole 51 includes a first hole section 511 and a second hole section 512 connected together. The second hole section 512 has an enlarged diameter section 5121, the maximum radial dimension of which is greater than that of the first hole section 511. The snap-fit ​​protrusion 521 enters from the first hole section 511 into the second hole section 512 and snaps into the enlarged diameter section 5121. The cooperation between the snap-fit ​​protrusion 521 and the enlarged diameter section 5121 provides stable support and positioning for the insertion tube 52, preventing accidental loosening or detachment of the insertion tube 52 during cooking or cleaning, and ensuring the normal operation of cooking and cleaning functions. At the same time, this design also allows for quick release of the insertion tube 52 during disassembly, improving the convenience of disassembly and assembly operations.

[0045] like Figures 1 to 4As shown, the insertion hole 51 also includes a third hole section 513 communicating with the second hole section 512. The first hole section 511, the second hole section 512, and the third hole section 513 are arranged sequentially along the axial direction of the insertion hole 51. The second hole section 512 also has a guide slope 5122 and a limiting slope 5123. The guide slope 5122 connects the enlarged diameter section 5121 and the first hole section 511, and the limiting slope 5123 connects the enlarged diameter section 5121 and the third hole section 513. After the snap-fit ​​protrusion 521 is guided and engaged with the guide slope 5122, it is stopped by the limiting slope 5123, so that the snap-fit ​​protrusion 521 is snapped into the enlarged diameter section 5121. The nozzle 30 is detachably disposed in the third hole section 513. The setting of the guide slope 5122 and the limiting slope 5123 further optimizes the insertion and removal process of the insertion tube 52 and reduces the difficulty of operation. The guide bevel 5122 helps the locking protrusion 521 smoothly enter the expansion section 5121, while the limiting bevel 5123 ensures the correct positioning of the insertion tube 52, preventing over-insertion or incomplete insertion, and ensuring a stable connection between the nozzle 30 and the insertion tube 52. Meanwhile, the nozzle 30 is detachably mounted within the third hole section 513, enhancing the ease of cleaning and replacement flexibility of the nozzle 30.

[0046] The nozzle 30 includes a spray base that is pluggably disposed within the third orifice section 513 and a nozzle body that is rotatably snapped onto the spray base. The spray base has a locking platform, and the nozzle body has a hook that engages with the locking platform. The hook head slidably engages with the top surface of the locking platform. This snap-fit ​​method not only stably mounts the nozzle body onto the spray base but also, through the cooperation of the locking platform and the hook, enables quick assembly and disassembly of the nozzle body, simplifying the cleaning process and enhancing ease of use.

[0047] In Embodiment 2 of the cover assembly, the difference from Embodiment 1 lies in the location of the plug-in structure. For example... Figure 5 and Figure 6 As shown, in Embodiment 2 of the cover assembly, when the insertion tube 52 is mounted on the cover 10, the transmission structure 61 includes a transmission arm 611 and a pipe connector portion 612 mounted on the transmission arm 611, with an insertion hole 51 located on the pipe connector portion 612. When the insertion tube 52 is fixed to the cover 10, this configuration makes the connection point of the nozzle 30 more stable, reduces the impact of the cover 10 on the connection point of the nozzle 30 during movement, protects the nozzle 30 and its internal delivery pipe, and reduces maintenance costs. Simultaneously, the insertion hole 51 located on the pipe connector portion 612 simplifies the interface between the transmission structure 61 and the nozzle 30, reducing assembly steps.

[0048] It should be noted that, specifically, the insertion tube 52 and the cover 10 are integrally formed. The pipe connector 612 and the transmission arm 611 are separate structures, with the pipe connector 612 integrally formed at one end of the liquid delivery pipe.

[0049] like Figure 5 and Figure 6 As shown, the cover 10 includes a cover plate 11 and a connecting tube seat 13 connected to the cover 10. The connecting tube seat 13 is connected to the insertion tube 52. The nozzle 30 is detachably suspended on the connecting tube seat 13, and the interior of the nozzle 30 is connected to the connecting tube seat 13. Designing the nozzle 30 to be detachably suspended on the connecting tube seat 13 increases the ease of maintenance of the nozzle 30. When cleaning is required, the detachability of the nozzle 30 allows users to directly disassemble and clean the nozzle 30, avoiding cleaning dead spots. The connection between the interior of the nozzle 30 and the connecting tube seat 13 ensures that the cleaning fluid can be accurately delivered to the nozzle 30, while also facilitating the replacement and cleaning of the nozzle 30.

[0050] The cover assembly of this application also includes an upper cover 74, which has an opening. The cover 10 is closable on the upper cover 74. When the cover 10 is opened from the opening, the cover 10 is in the open position. When the cover 10 closes the opening, the cover 10 is in the closed position.

[0051] This application also provides a cooking utensil, such as Figure 7 and Figure 8 As shown, an embodiment of the cooking appliance includes a base and a cover assembly disposed on the base, the cover assembly being the aforementioned cover assembly. Because the aforementioned cover assembly can solve the problem of incomplete cleaning due to cleaning dead zones at the installation position between the cover and the transmission structure in related technologies, including this cover assembly can solve the same technical problem. The base includes a shell 71 or a seat; in this embodiment, the base includes a shell 71.

[0052] The cooking appliance also includes a motor mounted on the base, which drives the transmission structure 61. The motor-driven transmission structure 61 ensures the automatic closing and opening of the lid 10, improving the intelligence level of the cooking appliance and the ease of user operation.

[0053] like Figure 7 and Figure 8 As shown, the cooking appliance also includes a housing 71 and a motor mounted on the housing 71, which drives a transmission structure 61. The motor drives the transmission structure 61, enabling the lid 10 to automatically switch between an open and closed position. Furthermore, when the lid 10 is in the closed position, the transmission structure 61 automatically retracts the nozzle 30 into or out of the lid 10, simplifying user operation and enhancing the user experience.

[0054] The cooking appliance also includes a rotating shaft, and the top cover 74 and the transmission structure 61 are both pivotally connected to the outer casing 71 via the rotating shaft. The top cover 74 and the transmission structure 61 rotate about the same axis of rotation, which facilitates the arrangement of the transmission structure.

[0055] like Figure 7 and Figure 8 As shown, the cooking appliance also includes an inner pot 72 housed within the outer casing 71, a stirring structure rotatably mounted on the inner pot 72, and a water tank 73 mounted on the outer casing 71. The nozzle 30 is connected to the water tank 73. The stirring structure can stir the ingredients in the inner pot 72, enabling a stir-frying function. The cooking appliance also includes an active transmission component and a driven transmission component. The active transmission component is rotatably mounted on the outer casing 71, and a motor is driven and connected to it. The active transmission component has active teeth. The driven transmission component is mounted on the transmission structure 61 and has driven teeth that can mesh with the active teeth. The direct connection between the water tank 73 and the nozzle 30 ensures timely supply of cleaning solution, improving the cleaning response speed and efficiency. Driven by the motor, the active and driven transmission components work together to drive the transmission structure 61, ensuring the automated operation of the cover 10 and the nozzle 30, thus improving the intelligence level and ease of operation of the cooking appliance. Furthermore, since the nozzle 30 can retract into the cover, it prevents the nozzle from being exposed outside the cover and scraping against the rotating stirring structure.

[0056] The inner pot 72 has a rim that communicates with the outside of the cooking appliance, and the lid 74 is detachably and closably positioned over the rim.

[0057] The cooking appliance also includes a driven pair transmission component, which is mounted on the upper cover 74. The driven pair transmission component has driven teeth that can mesh with the driving teeth. Driven by a motor, the upper cover 74 is driven to swing by the cooperation of the driving and driven pairs transmission components, thereby opening or closing the pot opening. A single motor can control the opening or closing of the upper cover 74, the lid 10, and the extension or retraction of the nozzle 30, significantly reducing manufacturing costs.

[0058] The active transmission component includes a drive shaft and a first gear and a second gear mounted on the drive shaft. A motor is connected to the drive shaft for driving. The first and second gears are arranged axially along the drive shaft. The first gear has a driving tooth capable of meshing with the driven pair gear, and the second gear has a driving tooth capable of meshing with the driven tooth. Both the first and second gears are incomplete gears. When the drive shaft rotates, the first gear meshes with the driven pair gear, and the second gear meshes with the driven tooth. By configuring the first and second gears as incomplete gears, and utilizing their alternating meshing with the corresponding driven pair gear and driven tooth, the motor can drive the upper cover 74 and the cover body 10 to open or close sequentially via the active transmission component, the driven pair gear, and the driven tooth.

[0059] The driven pair transmission component is a first arc-shaped rack, which extends around the rotation axis of the driving transmission component and has driven teeth. The driven transmission component is a second arc-shaped rack, which also extends around the rotation axis of the driving transmission component and has driven teeth. Both the first and second arc-shaped racks are arc-shaped structures. This structure, used in conjunction with the incomplete gears of the first and second gears, further simplifies the structure of the driven pair transmission component and reduces costs, based on the premise that the motor drives the upper cover 74 and the cover body 10 to open or close sequentially through the driving transmission component, driven teeth, and driven teeth.

[0060] In this embodiment, along the axial direction of the drive shaft, the projections of some of the driving teeth on the first gear overlap with the projections of some of the driving teeth on the second gear. With this structure, the switching between the first and second gears and their corresponding driven teeth is smoother, reducing the likelihood of jamming.

[0061] In this embodiment, the cooking appliance is a stir-fry machine; in other embodiments, the cooking appliance is a dough mixer, a multi-functional pot, or a soy milk maker.
