[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] This embodiment provides a spray structure 100 that can achieve targeted cleaning of the front, back, left, and right side walls of the inner liner 210. The rotation of the spray arm 20 does not require electricity, saving energy. Figure 1 As shown, the spray structure 100 includes a connecting pipe 10 and a spray arm 20. One end of the connecting pipe 10 is connected to the top of the inner liner 210 (see here). Figure 5 The spray arm 20 includes at least two straight sections 21 and a bent section 22. The at least two straight sections 21 are radially distributed. The connection position of the at least two straight sections 21 is rotatably connected to and communicates with the other end of the connecting pipe 10. The free end of each straight section 21 is connected to a bent section 22. The bent section 22 bends clockwise or counterclockwise at a preset angle relative to the end of the straight section 21 away from the connection position. The bending direction of the at least two bent sections 22 is the same.

[0050] The aforementioned spray structure 100, by providing at least two straight sections 21, and each straight section 21 corresponding to a bend 22, allows water to enter from the connecting pipe 10 into the at least two straight sections 21 and then spray out from the at least two bends 22. The water sprayed from the at least two bends 22 can reach the sidewalls, thereby cleaning the sidewalls of the inner liner 210. Furthermore, the bends of the at least two bends 22 are aligned. When water is sprayed from the two bends 22, the high-pressure water acts on the sidewalls of the inner liner 210. Due to the reaction force, the bends 22 rotate in the opposite direction. Figure 1 From a top-down perspective, after the bent portion 22 is subjected to force, it rotates counterclockwise. At least two bent portions 22 are subjected to the same reaction force, ensuring that the forces at both ends of the straight portion 21 are balanced. This allows the entire spray arm 20 to continuously rotate under the action of the reaction force, cleaning all the front, back, left, and right side walls of the inner tank 210. Therefore, this spray structure 100 can achieve targeted cleaning of the front, back, left, and right side walls of the inner tank 210. The rotation of the spray arm 20 does not rely on a motor, saving energy.

[0051] In this embodiment, as Figure 1 As shown, there are two straight sections 21, and the included angle between the two straight sections 21 is 180°.

[0052] Of course, in other embodiments, the number of straight sections 21 can be set to three, four or more, and each straight section 21 is provided with a bent section 22 at both ends. Thus, multiple bent sections 22 rotate at the same time, the water spray range is larger and the cleaning effect is better. This is not limited here.

[0053] Optionally, the angle between the bent portion 22 and the corresponding straight portion 21 is obtuse, making the water flow smoother. In this embodiment, the angle between the bent portion 22 and the straight portion 21 is 120°. In other embodiments, this angle can be adjusted appropriately, such as 130°, 110°, 100°, etc., which are not limited here.

[0054] Optionally, the connection position of at least two straight sections 21 is also... Figure 1 The second connecting portion 23 indicated in the middle has at least two straight portions 21 arranged circumferentially at intervals along it. It can be understood that the connecting pipe 10 is connected to the second connecting portion 23.

[0055] Furthermore, see also Figure 1 and Figure 5 The spray structure 100 also includes two spray arm retaining rings 40. The second connecting part 23 has an annular sidewall, and the inner side of the annular sidewall has protrusions that can engage with the two spray arm retaining rings 40. The connecting pipe 10 has two limiting flanges 11 spaced apart along its axial direction at the end connected to the second connecting part 23. When connecting the connecting pipe 10 and the second connecting part 23, the two spray arm retaining rings 40 are first arranged between the two limiting flanges 11, and then inserted into the annular sidewall. The spray arm retaining rings 40 are rotated so that the two spray arm retaining rings 40 are respectively engaged and fixed with the corresponding engaging protrusions. With this arrangement, the connecting pipe 10 is fixed, and the spray arm retaining rings 40 and the spray arm 20 rotate simultaneously. The spray arm retaining rings 40 are a structure in the prior art. In other embodiments, other methods can be used to make the spray arm 20 rotate relative to the connecting pipe 10, which are not limited here.

[0056] Optionally, such as Figure 2 and Figure 3 As shown, the spray structure 100 also includes a water-scattering head 30, which is arranged one-to-one with the bend 22. The water-scattering head 30 is connected to the free end of the bend 22 to scatter the water flow in multiple directions. Through the above arrangement, the water sprayed from the bend 22 is dispersed in multiple directions with the center of the bend 22 as the axis, so that the water sprayed onto the inner tank 210 is changed from one point to multiple points, resulting in a larger cleaning area and better cleaning effect.

[0057] In an optional embodiment, such as Figure 2 and Figure 3As shown, the bending part 22 includes a main body 221, a water outlet 222, and a blocking part 223. The main body 221 is connected to one end of the straight part 21. The water outlet 222 is connected to the end of the main body 221 away from the straight part 21 and has a plurality of first water outlet holes 2221. The blocking part 223 is connected to the end of the water outlet 222 away from the main body 221. A water-containing space 31 is formed inside the scattering water head 30 and is connected to the main body 221. The plurality of first water outlet holes 2221 are located in the water-containing space 31. The scattering water head 30 also has a scattering hole 32 connected to the water-containing space 31. At least part of the blocking part 223 is located in the scattering hole 32. With the above configuration, the main body of the water hole 221 enters the water outlet 222 and enters the water holding space 31 through several first water outlet holes 2221. The water holding space 31 is evenly filled. Due to the action of the blocking part 223, when the water overflows from the water holding space 31, it passes through the scattering hole 32. The scattering hole 32 is partially occupied by the blocking part 223, which forces the water to spray out along the side wall of the scattering hole 32. As a result, the water sprays out along the side wall of the scattering hole 32 in multiple directions, resulting in a large spray area.

[0058] Optionally, such as Figure 3 As shown, the walls of the scattering hole 32 are tapered, causing the water flow to be sprayed in an umbrella shape.

[0059] Optionally, such as Figure 3 As shown, the blocking part 223 is fixedly connected to the water outlet part 222. The diameter of the blocking part 223 is D1. The water holding space 31 and the scattering hole 32 are connected through a clearance hole 33. The diameter of the clearance hole 33 is D2, where D2 > D1. With the above arrangement, when the scattering water head 30 is installed, the blocking part 223 can pass through the clearance hole 33 to avoid interference. At the same time, the setting of the clearance hole 33 prevents the scattering hole 32 from being directly connected to the water holding space 31, which would cause the wall thickness of the scattering hole 32 to be too thin and the strength insufficient.

[0060] Optionally, the blocking part 223 and the water outlet part 222 are connected by a first connecting part 224. The diameter of the first connecting part 224 is smaller than the diameter of the clearance hole 33 and the first connecting part 224 is provided through the clearance hole 33, which ensures that the water flow can quickly pass through the small gap between the two, increasing the water flow rate and improving the cleaning ability.

[0061] In an optional embodiment, see Figure 2 and Figure 3 The blocking part 223 is a columnar body. In another optional embodiment, the blocking part 223 can also be a sphere or a cone, etc., which is not limited here.

[0062] Optionally, a plurality of first water outlet holes 2221 are evenly distributed around the circumference of the water outlet portion 222, resulting in a faster flow rate. In another embodiment, the first water outlet holes 2221 may also be distributed on the side where the water outlet portion 222 connects to the first connecting portion 224, which is not limited here.

[0063] In this embodiment, the water scattering head 30 is connected to the main body 221 by a thread. In other embodiments, a snap-fit ​​connection may also be used, which is not limited here.

[0064] In another alternative embodiment, the blocking part 223 can also be detachably connected to the water outlet part 222. After the diffuser head 30 is installed, the blocking part 223 and the water outlet part 222 are connected, for example by a threaded connection. Thus, the clearance hole 33 can be made smaller than the diameter of the blocking part 223, allowing only the first connecting part 224 to pass through.

[0065] To further improve the cleaning effect on the top of the inner liner 210, such as Figure 4 As shown, multiple second water outlets 2121 are provided on the upper side of the straight section 21, and at least two of the multiple second water outlets 2121 have different water outlet directions. With the above arrangement, the multiple water outlets on the straight section 21 are used to clean the heating element at the top of the inner tank 210 and the bottom (the bottom is mainly cleaned by water flowing down from the inner wall), and the different directions can cover a wider cleaning area.

[0066] In an optional embodiment, such as Figure 4 As shown, the straight section 21 includes a body 211 and multiple plugs 212. The body 211 has mounting holes (not labeled) for installing the plugs 212. The plugs 212 are interference-fitted into the mounting holes. A second water outlet 2121 is formed on the plug 212. The top of the plug 212 is an inclined surface. When drilling, the second water outlet 2121 is based on this inclined surface and is essentially perpendicular to it. Therefore, by rotating the plug 212, different orientations of the second water outlets 2121 can be easily achieved. Optionally, the plugs 212 are made of a soft material, such as rubber, which allows for a good seal with the mounting holes.

[0067] Of course, in another embodiment, the plug 212 and the straight section 21 can also be manufactured as a single piece, which is not limited here.

[0068] Optionally, a second water outlet 2121 can also be provided on the lower side of the straight section 21 to clean the bottom wall of the inner tank 210 in a targeted manner, which will not be described in detail here.

[0069] Optionally, the spray arm 20 is a plastic part (excluding the end cap 212) and is formed by hot-melt splicing of two parts, upper and lower. Understandably, when the spray arm 20 is entirely made of plastic, the bent shape is not easily formed in one piece; for example, demolding is difficult. In other words, it requires a horizontal plane... Figure 4 The spray arm 20 is manufactured by cutting it into upper and lower parts separately, and then hot-melt splicing them together to form the spray arm 20.

[0070] Of course, in other embodiments, such as when the spray arm 20 is made of metal or other materials, it can be integrally molded, and this is not limited here.

[0071] This embodiment also provides an inner liner assembly 200, which includes an inner liner 210 and the aforementioned spray structure 100, the spray structure 100 being connected to the top of the inner liner 210. By employing the spray structure 100, the inner liner assembly 200 allows for better targeted cleaning of multiple inner walls of the inner liner 210, and the spray arm 20 can rotate without the need for a motor, saving power.

[0072] Optionally, see [link to relevant documentation] Figure 5 The inner liner 210 has a through hole, and the connecting protrusion 230 is installed on the inner liner 210 and is corresponding to the through hole. The connector 220 is connected to the connecting protrusion 230 by a thread. Specifically, the outer wall of the connector 220 is threaded to the inner wall of the connecting protrusion 230, and the connector 220 and the inner liner 210 are sealed to prevent moisture from escaping. Furthermore, the outer wall of the top of the connecting pipe 10 is threaded to the inner wall of the connector 220. When the inner liner 210 needs to be cleaned, the two are connected. After cleaning, the connecting pipe 10 can be quickly removed.

[0073] This embodiment also provides a cooking appliance, including the aforementioned inner pot assembly 200. By employing the inner pot assembly 200, the cooking appliance can perform comprehensive and targeted cleaning of the inner pot 210, and the spray arm 20 can rotate without the need for a motor, saving power.

[0074] It should be noted that the cooking appliance can be a steam oven, oven, or steam-grill combination oven, etc., with an inner liner 210, and is not limited here.

[0075] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
