Description

Technical Field

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

[0002] A stir-fry machine is a kitchen appliance that integrates cooking and automation technologies. It simulates manual stir-frying by using a built-in heating and stirring system to automatically complete the stir-frying process. Existing stir-fry machines generally include a pot body, a lid, a stirring mechanism, and a cleaning mechanism. Both the stirring and cleaning mechanisms are located inside the pot body. The stirring mechanism performs the stirring function, thus simulating the actual stir-frying process, while the cleaning mechanism cleans the pot body and lid.

[0003] In related technologies, in order to improve the cleaning effect of the cleaning structure, the cleaning structure is rotatably configured. Specifically, the cleaning structure is rotated through a drive component and bearings, etc. However, such a structure makes the cleaning structure more complex. Utility Model Content

[0004] The main objective of this invention is to provide a nozzle assembly and a cooking appliance having the same, in order to solve the problem of complex cleaning structures in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a nozzle assembly is provided, comprising: a connecting pipe; and a nozzle component disposed at the end of the connecting pipe and rotatably connected to the connecting pipe, the nozzle component having a cavity and a first water outlet channel, the cavity communicating with the connecting pipe, the first end of the first water outlet channel communicating with the cavity, the second end of the first water outlet channel being a first water outlet, and the line connecting the first water outlet and the rotation center of the nozzle component having a first preset angle with the water outlet direction of the first water outlet.

[0006] Using the technical solution of this utility model, the nozzle component and the connecting pipe are rotatably connected. The nozzle component is provided with a cavity and a first water outlet channel. The cavity is connected to the connecting pipe, the first end of the first water outlet channel is connected to the cavity, and the second end of the first water outlet channel is the first water outlet. The line connecting the first water outlet and the rotation center of the nozzle component has a first preset angle with the water outlet direction of the first water outlet. With the above arrangement, the liquid enters the cavity through the connecting pipe and then enters the first water outlet channel through the cavity. The liquid is discharged through the first water outlet. Since the line connecting the first water outlet and the rotation center of the nozzle component has a first preset angle with the water outlet direction of the first water outlet, the force in the water outlet direction can be divided into a radial component along the outer circle of the nozzle component and a tangential component along the outer circle of the nozzle component. Under the action of the tangential component, the nozzle component can rotate, that is, the nozzle component can rotate relative to the connecting pipe. This setup only requires the cooperation of the liquid and the first water outlet channel to achieve automatic rotation of the nozzle, thus simplifying the overall structure. Therefore, the technical solution of this application effectively solves the problem of complex cleaning structures in related technologies.

[0007] Furthermore, the nozzle component is also provided with a second water outlet channel, which is spaced apart from the first water outlet channel. The first end of the second water outlet channel is connected to the cavity, and the second end of the second water outlet channel is a second water outlet. The water outlet direction of the second water outlet is the same as that of the first water outlet in the circumferential direction of the nozzle component. The provision of the second water outlet channel can improve the rotation effect of the nozzle component, and because the first and second water outlet channels are spaced apart, the rotation of the nozzle component is more stable.

[0008] Furthermore, the line connecting the second water outlet and the rotation center of the nozzle component has a second preset angle with the water outlet direction, and the second preset angle b and the first preset angle a satisfy: -30°≤ab≤30°. The above settings ensure that the nozzle component can rotate.

[0009] Furthermore, the bottom surface of the first water outlet is lower than the bottom surface of the second water outlet. This arrangement allows for a larger cleaning range and area, thereby improving the cleaning effect.

[0010] Furthermore, the nozzle is also equipped with a flow divider, which is located within the cavity. The width of the flow divider gradually increases from the top to the bottom of the cavity. The flow divider guides the liquid flow, making it easier for the liquid to enter the first and second water outlet channels.

[0011] Furthermore, the flow divider has a first guide surface and a second guide surface. The first guide surface is connected to the bottom surface of the first water outlet channel, and the second guide surface is connected to the bottom surface of the second water outlet channel. This arrangement ensures the effectiveness of the flow channel and avoids right angles that could obstruct the liquid flow.

[0012] Furthermore, the nozzle assembly also includes a connecting structure, which is disposed on the nozzle component and connected to the connecting pipe, or the connecting structure is disposed on the connecting pipe and connected to the nozzle component. The connecting structure enables a rotatable connection between the connecting pipe and the nozzle component.

[0013] Furthermore, the connecting structure includes a first connecting arm and a second connecting arm, both of which are mounted on the nozzle component. The first connecting arm has a first bend on its side away from the nozzle component, and the second connecting arm has a second bend on its side away from the nozzle component. Both the first and second bends are connected to the connecting pipe. The arrangement of the first and second connecting arms improves the stability of the connection, and the first and second bends can engage with the connecting pipe for positioning.

[0014] Furthermore, the connecting pipe is provided with a protrusion, and both the first bend and the second bend are located above the protrusion and abut against it. The first bend and the second bend can abut against the protrusion, thereby making the connection between the connecting pipe and the nozzle more stable.

[0015] Furthermore, the top of the cavity has an opening, and there is a gap between the connecting pipe and the opening. This arrangement ensures smoother rotation of the connecting pipe and the nozzle.

[0016] Furthermore, the nozzle assembly also includes a positioning element, which is disposed between the nozzle component and the connecting pipe. The positioning element enables the nozzle component and the connecting pipe to be positioned, thereby ensuring the stability of the connection between the nozzle component and the connecting pipe.

[0017] Furthermore, the positioning component includes an annular positioning plate, which is connected to the bottom of the cavity and extends towards the top of the cavity. The annular positioning plate is inserted into the connecting pipe, and an clearance opening is provided on the annular positioning plate, which communicates with the first water outlet channel. The above configuration ensures the stability of the connection.

[0018] Furthermore, the connecting pipe includes a first pipe section and a second pipe section, which are connected to each other. A reduced-diameter section is provided on the side of the first pipe section facing the second pipe section, and the diameter of the second pipe section is larger than the diameter of the reduced-diameter section. This arrangement enables pressurization, thereby allowing for faster rotation.

[0019] According to another aspect of this utility model, a cooking appliance is provided, comprising: a pot body; a lid, which is closable and can be opened and closed on the pot body; a swing arm connected between the pot body and the lid, the swing arm being swingably disposed and having a water guide pipe disposed inside the swing arm; and a nozzle assembly disposed inside the lid and communicating with the water guide pipe, the nozzle assembly being the aforementioned nozzle assembly. The aforementioned nozzle assembly can rotate relative to the connecting pipe, and the overall structure is relatively simple. Therefore, the cooking appliance having the aforementioned nozzle assembly also has the aforementioned advantages. Attached Figure Description

[0033] 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.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0035] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. 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.

[0036] like Figure 1 and Figure 2 as well as Figure 6 As shown, in this embodiment, the nozzle assembly includes a connecting pipe 10 and a nozzle component 20. The nozzle component 20 is disposed at the end of the connecting pipe 10 and rotatably connected to the connecting pipe 10. The nozzle component 20 is provided with a cavity 21 and a first water outlet channel 22. The cavity 21 communicates with the connecting pipe 10. The first end of the first water outlet channel 22 communicates with the cavity 21. The second end of the first water outlet channel 22 is a first water outlet 221. The line connecting the first water outlet 221 and the rotation center of the nozzle component 20 has a first preset angle with the water outlet direction of the first water outlet 221.

[0037] Using the technical solution of this embodiment, the nozzle component 20 is rotatably connected to the connecting pipe 10. The nozzle component 20 is provided with a cavity 21 and a first water outlet channel 22. The cavity 21 is connected to the connecting pipe 10. The first end of the first water outlet channel 22 is connected to the cavity 21. The second end of the first water outlet channel 22 is the first water outlet 221. The line connecting the first water outlet 221 and the rotation center of the nozzle component 20 has a first preset angle with the water outlet direction of the first water outlet 221. With the above configuration, liquid enters the cavity 21 through the connecting pipe 10, and then enters the first water outlet channel 22 through the cavity 21. The liquid is discharged through the first water outlet 221. Since the line connecting the rotation center of the first water outlet 221 and the nozzle 20 has a first preset angle with the water outlet direction of the first water outlet 221, the force in the water outlet direction can be divided into a radial component along the outer circle of the nozzle 20 and a tangential component along the outer circle of the nozzle 20. Under the action of the tangential component, the nozzle 20 can rotate, that is, the nozzle 20 can rotate relative to the connecting pipe 10. This configuration only requires the cooperation of the liquid and the first water outlet channel 22 to achieve automatic rotation of the nozzle 20, thus making the overall structure relatively simple. Therefore, the technical solution of this embodiment effectively solves the problem of complex cleaning structures in related technologies.

[0038] Specifically, both the nozzle component 20 and the connecting pipe 10 are made of food-grade plastic.

[0039] like Figures 3 to 5As shown, in this embodiment, the nozzle 20 is further provided with a second water outlet channel 23, which is spaced apart from the first water outlet channel 22. The first end of the second water outlet channel 23 is connected to the cavity 21, and the second end of the second water outlet channel 23 is a second water outlet 231. The water outlet direction of the second water outlet 231 is similar to that of the first water outlet 221 in the circumferential direction of the circumference of the nozzle 20. The provision of the second water outlet channel 23 can improve the rotation effect of the nozzle 20, and because the first water outlet channel 22 and the second water outlet channel 23 are spaced apart, the rotation of the nozzle 20 is more stable.

[0040] It should be noted that the aforementioned "same trend" means that the directions of the first outlet 221 and the second outlet 231 are both decomposed into radial and tangential directions, and the tangential directions of the first outlet 221 and the second outlet 231 coincide after rotating around the rotation center by a certain angle. For example... Figures 1 to 5 As shown, in this embodiment, the line connecting the rotation center of the second water outlet 231 and the nozzle component 20 has a second preset angle with the water outlet direction of the second water outlet 231. The second preset angle b and the first preset angle a satisfy: -30°≤ab≤30°. The above setting ensures that the nozzle component 20 can rotate.

[0041] like Figures 3 to 5 As shown, in this embodiment, the bottom surface of the first water outlet 221 is lower than the bottom surface of the second water outlet 231. This arrangement allows for a larger cleaning range and area, thereby improving the cleaning effect.

[0042] like Figures 3 to 5 As shown, in this embodiment, the nozzle 20 is also provided with a flow divider 30, which is disposed inside the cavity 21. The width of the flow divider 30 gradually increases from the top to the bottom of the cavity 21. The flow divider 30 can guide the liquid, thereby making it easier for the liquid to enter the first water outlet channel 22 and the second water outlet channel 23.

[0043] like Figures 3 to 5 As shown, in this embodiment, the flow divider 30 has a first guide surface 31 and a second guide surface 32. The first guide surface 31 is connected to the bottom surface of the first water outlet channel 22, and the second guide surface 32 is connected to the bottom surface of the second water outlet channel 23. The above arrangement can ensure the effect of the flow channel and avoid right angles that would obstruct the liquid.

[0044] like Figures 1 to 6As shown, in this embodiment, the nozzle assembly further includes a connecting structure 40. The connecting structure 40 is disposed on the nozzle component 20 and connected to the connecting pipe 10, or the connecting structure 40 is disposed on the connecting pipe 10 and connected to the nozzle component 20. The connection structure 40 enables a rotatable connection between the connecting pipe 10 and the nozzle component 20.

[0045] like Figures 1 to 6 As shown, in this embodiment, the connecting structure 40 includes a first connecting arm 41 and a second connecting arm 42. Both the first connecting arm 41 and the second connecting arm 42 are disposed on the nozzle component 20. The first connecting arm 41 has a first bending portion 411 on the side away from the nozzle component 20, and the second connecting arm 42 has a second bending portion 421 on the side away from the nozzle component 20. The first bending portion 411 and the second bending portion 421 are connected to the connecting pipe 10. The arrangement of the first connecting arm 41 and the second connecting arm 42 can improve the stability of the connection, and the first bending portion 411 and the second bending portion 421 can be matched with the connecting pipe 10 for limiting.

[0046] like Figures 1 to 7 As shown, in this embodiment, the connecting pipe 10 is provided with a protrusion 11, and the first bend 411 and the second bend 421 are both located above the protrusion 11 and abut against the protrusion 11. The first bend 411 and the second bend 421 can abut against the protrusion 11, thereby making the connection between the connecting pipe 10 and the nozzle component 20 more stable.

[0047] Furthermore, the first connecting arm 41 and the second connecting arm 42 have a certain degree of elasticity, which allows the first connecting arm 41 and the second connecting arm 42 to swing, thus enabling the nozzle component 20 and the connecting pipe 10 to be disassembled and assembled.

[0048] like Figures 1 to 6 As shown, in this embodiment, the top of the cavity 21 has an opening 211, and there is a gap between the connecting pipe 10 and the opening 211. The above arrangement can ensure smoother rotation of the connecting pipe 10 and the nozzle 20.

[0049] Specifically, the above intervals are between 0.5mm and 10mm. If it is less than 0.5mm, jamming and poor rotation are likely to occur; if it exceeds 5mm, the nozzle part 20 will shake too much.

[0050] The aforementioned interval is preferably 1.8 mm to 2.5 mm.

[0051] like Figures 1 to 6 As shown, in this embodiment, the nozzle assembly further includes a positioning element 50, which is disposed between the nozzle component 20 and the connecting pipe 10. The positioning element 50 enables the positioning of the nozzle component 20 and the connecting pipe 10, thereby ensuring the connection stability between the nozzle component 20 and the connecting pipe 10.

[0052] like Figures 1 to 6 As shown, in this embodiment, the positioning member 50 includes an annular positioning plate 51, which is connected to the bottom of the cavity 21 and extends toward the top of the cavity 21. The annular positioning plate 51 is inserted into the connecting pipe 10, and an avoidance opening 511 is provided on the annular positioning plate 51, which communicates with the first water outlet channel 22. The above-mentioned arrangement can ensure the stability of the connection.

[0053] like Figures 1 to 6 As shown, in this embodiment, anti-friction ribs are provided on the outer wall of the annular positioning plate 51. This arrangement facilitates easier rotation of the nozzle component 20 and the connecting pipe 10.

[0054] like Figure 1 , Figure 2 as well as Figure 7 As shown, in this embodiment, the connecting pipe 10 includes a first pipe section 12 and a second pipe section 13. The first pipe section 12 is connected to the second pipe section 13. A reduced diameter section 121 is provided on the side of the first pipe section 12 facing the second pipe section 13, and the diameter of the second pipe section 13 is larger than the diameter of the reduced diameter section 121. The above arrangement enables pressurization, thereby allowing for faster rotation speed.

[0055] It should be noted that the minimum cross-sectional area of ​​the reduced diameter section 121 is c, and the cross-sectional area of ​​the first pipe section 12 is d, where c and d satisfy the condition: 2 ≤ d / c ≤ 20. If d / c < 2, insufficient pressure will result, making it difficult for the nozzle component 20 to rotate. If d / c > 20, excessive water pressure will lead to a decrease in water output, which will affect the cleaning effect.

[0056] Specifically, in this embodiment, d / c = 9.

[0057] According to another aspect of this application, a cooking utensil is provided, such as Figures 8 to 10 As shown, the cooking appliance of this embodiment includes: a pot body 60, a lid 70, a swing arm 80, and a nozzle assembly. The lid 70 is closable and can be opened and closed on the pot body 60; the swing arm 80 is connected between the pot body 60 and the lid 70, and is swingable, with a water guide pipe 81 disposed inside the swing arm 80; the nozzle assembly is disposed inside the lid 70 and communicates with the water guide pipe 81, and the nozzle assembly is the aforementioned nozzle assembly. The aforementioned nozzle component 20 can rotate relative to the connecting pipe 10, and the overall structure is relatively simple. Therefore, the cooking appliance with the aforementioned nozzle assembly also has the aforementioned advantages.

[0058] Specifically, in this embodiment, the cover 70 includes a first cover and a second cover. The first cover is closable and covers the opening of the pot body 60, and the first cover has a feeding port. The second cover is closable and covers the feeding port. A driving member is drivenly connected to the first cover and the second cover, and the driving member can drive the first cover and the second cover to open or close.

[0059] like Figures 8 to 10 As shown, in this embodiment, the driving element can drive the first cover and the second cover to open or close, meaning that the driving element can drive the first cover to switch between an open state and a closed state, and the driving element can drive the second cover to switch between an open state and a closed state. Furthermore, in this embodiment, the driving element is a single driving component. Using one driving component to simultaneously drive the opening and closing of both covers simplifies the driving structure and reduces costs compared to using two separate driving components to drive the two covers.

[0060] like Figures 8 to 10 As shown, in this embodiment, the cooking appliance also includes a transmission mechanism, through which the driving component is driven to the first lid and the second lid respectively. By setting a transmission mechanism to achieve the driving connection between the driving component and the first lid, as well as between the driving component and the second lid, compared to directly connecting the driving component to the first and second lids, the transmission structure offers the advantage of flexibility, easily meeting different lid-opening requirements.

[0061] For example, in this embodiment, the drive unit can drive the first cover and the second cover to open or close sequentially through the transmission mechanism, increasing the ways to use the cooking appliance.

[0062] Specifically, the driving component first drives the second cover to open via a transmission mechanism. After the second cover opens, the driving component then drives the first cover to open via the transmission mechanism. When closing the lid, the first cover closes first, and the second cover closes after the first cover closes.

[0063] like Figures 8 to 10 As shown, in this embodiment, the transmission mechanism includes a driving transmission member, a first driven transmission member, and a second driven transmission member. The driving transmission member is rotatably mounted on the pot body 60, and a driving member is drivenly connected to the driving transmission member. The driving transmission member has a driving tooth. The first driven transmission member is mounted on the first cover and has a first driven tooth capable of meshing with the driving tooth. The second driven transmission member is mounted on the second cover and has a second driven tooth capable of meshing with the driving tooth. Using the above structure, the transmission is achieved through a gear structure, which has the advantages of simple and stable transmission structure.

[0064] The active transmission component includes a drive shaft and a first gear and a second gear mounted on the drive shaft. A driving component is connected to the drive shaft. The first and second gears are arranged axially along the drive shaft. The first gear has a driving tooth capable of meshing with a first driven tooth, and the second gear has a driving tooth capable of meshing with a second driven tooth. Both the first and second gears are incomplete gears. When the drive shaft rotates, the first and second gears alternately mesh with their corresponding driven transmission components. By configuring the first and second gears as incomplete gears, and utilizing their alternating meshing with their corresponding driven transmission components, the driving component can drive the first and second covers to open or close sequentially via a transmission mechanism.

[0065] It should be noted that when the drive shaft rotates, the first gear and the second gear take turns meshing with the corresponding driven transmission components. The corresponding driven transmission components refer to the first gear corresponding to the first driven transmission component and the second gear corresponding to the second driven transmission component.

[0066] The first driven transmission component is a first arc-shaped rack, which extends around the rotation axis of the driving transmission component. A first driven tooth is disposed on the first arc-shaped rack. The second driven transmission component is a second arc-shaped rack, which extends around the rotation axis of the driving transmission component. A second driven tooth is disposed on the second arc-shaped rack. 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 first and second driven transmission components and reduces costs, while still enabling the driving component to drive the first and second covers to open or close sequentially via the transmission mechanism.

[0067] 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 transmission components is smoother, reducing the likelihood of jamming.

[0068] The number of teeth on both the first and second gears ranges from 3 to 50. Fewer than 3 teeth can lead to meshing problems, while more than 50 teeth result in small tooth features and difficult machining. In this embodiment, the number of teeth is 6 to 10. Specifically, overlapping teeth are called switching overlapping teeth, and the number can be 1 to 10. Fewer than 1 makes switching difficult, while more than 10 overlaps too much and can cause interference. In this embodiment, the number of switching overlapping teeth is 2 to 4. Specifically, the pitch circle diameter of the first and second gears is D1 (the theoretical circle diameter when the gears mesh). The tooth width L1 of the driving tooth is 2 to 30 mm. Fewer than 2 mm makes machining difficult and requires high precision; more than 30 mm results in a wide tooth width, excessive assembly space, and a tendency to wobble. In this embodiment, L1 is 6 to 10 mm.

[0069] The number of teeth in the first driven tooth of the first driven transmission component and the second driven tooth of the second driven transmission component is 3-50. Fewer than 3 teeth result in insufficient meshing and potential problems; more than 50 teeth result in small tooth features and difficult machining. In this embodiment, the number of teeth is 6-10. The first and second driven transmission components also have switching overlapping teeth, with 1-10 overlapping teeth. Fewer than 1 overlapping teeth makes switching difficult; more than 10 overlapping teeth lead to excessive overlap and potential interference. In this embodiment, the number of switching overlapping teeth is 2-4. The tooth width L3 of the first and second driven transmission components is 2-30mm. Fewer than 2mm makes machining difficult and requires high precision; more than 30mm results in excessive tooth width, excessive assembly space, and potential wobbling. In this embodiment, L3 is 5-8mm. In the description of this utility model, it should be understood that "multiple" refers to a quantity of two or more. The directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0070] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0071] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0072] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
