[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The steamer is provided with a plurality of steam generating chambers and a steamer assembly having a plurality of independent steaming chambers, wherein the steaming chamber has a steam inlet, and the steamer assembly comprises a plurality of vertically spaced juice collecting pans, a steaming enclosure provided between two adjacent juice collecting pans, and a steaming cover provided on the uppermost juice collecting pan, the steaming enclosure is provided with a first steam outlet, wherein some of the steam generating chambers are respectively connected with the middle and upper steaming chambers in a one-to-one correspondence through independent steam passages, the steam passage comprises a steam duct provided between two adjacent juice collecting pans, one of the steam ducts between the two adjacent juice collecting pans is provided close to the first steam outlet, the steam duct and the wall portion of the steam enclosure located around the first steam outlet form a vertically extending buffer channel, the steam inlet is located outside the buffer channel, and the buffer channel has a steam hole connected with the steaming chamber in which it is located.

[0006] In the above-mentioned anti-odor electric steamer, the steam duct includes a tube body and two first baffles connected to the tube body and extending vertically. There is a gap between the tube body and the steaming enclosure. The first baffle extends toward the steaming enclosure to cover at least part of the gap. The first steam outlet is located between the two first baffles.

[0007] In the above-mentioned electric steamer for preventing odor contamination, the first baffle blocks part of the gap, so that a gap is formed between the first baffle and the steaming enclosure, and the gap forms the steam hole.

[0008] In the above-mentioned anti-flavor electric steamer, the first baffle blocks all gaps, and the steam holes are small holes provided on the first baffle.

[0009] In the above-mentioned electric steamer for preventing odor transfer, the top of the steam duct is connected to the juice collecting tray, the uppermost juice collecting tray is fixedly connected to a support tube extending downward, the steam duct connected to the uppermost juice collecting tray is the upper steam duct, the support tube and the upper steam duct are arranged in a centrally symmetrical manner about the center of the uppermost juice collecting tray, and the bottom surface of the support tube is flush with the bottom surface of the upper steam duct.

[0010] In the above-mentioned anti-flavor electric steamer, the inner wall of the steaming enclosure is provided with anti-foolproof ribs, the anti-foolproof ribs avoid the steam duct, and the support tube is provided with an anti-foolproof baffle, the anti-foolproof ribs interfere with the anti-foolproof baffle to prevent the steaming enclosure and the adjacent upper juice receiving tray from being assembled in place.

[0011] In the above-mentioned anti-flavor electric steamer, two vertically extending second baffles are provided on the inner side of the steaming enclosure, the first steam outlet is provided between the two second baffles, and the part of the steaming enclosure located between the two second baffles, the two second baffles and the steam duct together form the buffer channel.

[0012] In the above-mentioned anti-odor electric steamer, the steam inlet is located on the other side opposite to the buffer channel; and / or the steam inlet is arranged near the bottom of the steaming cavity, and the first steam outlet is arranged near the top of the steaming enclosure.

[0013] In the above-mentioned electric steamer that prevents odor from spreading, the steam passage also includes a steam pipe arranged through the juice receiving tray, the lower end of the steam pipe is sleeved on the outside of the steam pipe of the lower juice receiving tray, and the upper end of the steam pipe is connected to the steam pipe of the upper juice receiving tray.

[0014] In the above-mentioned anti-odor electric steamer, the first steam outlet is arranged at a corner of the steaming enclosure, and the side walls of the steaming enclosure located on both sides of the first steam outlet and the steam conduit are enclosed to form the buffer channel.

[0015] Beneficial effects of the utility model:

[0016] 1. The steam duct and the wall of the steam enclosure located around the first steam outlet in the present invention form a vertically extending buffer channel. The steam inlet is located outside the buffer channel. The buffer channel has a steam hole connected to the steam chamber. In this way, the wall of the buffer channel can block the steam to a certain extent, so that the steam first passes through the steam hole and is decelerated before entering the buffer channel. After diffusing in the buffer channel, it is further decelerated and finally slowly discharged from the first steam outlet, thereby avoiding the risk of scalding the user due to excessive steam exhaust and improving the user experience; finally, one of the steam ducts between the two adjacent juice receiving trays is arranged close to the first steam outlet and is enclosed by the steam enclosure to form a buffer channel. There is no need to additionally set other baffle structures in the steam enclosure to enclose the buffer channel with the steam enclosure, thereby simplifying the structure of the steamer assembly.

[0017] 2. The steam conduit comprises a tube body and two first baffles connected to the tube body and extending vertically. A gap exists between the tube body and the steam enclosure. The first baffles extend toward the steam enclosure to at least partially block the gap. The first steam outlet is located between the two first baffles. Compared to using the entire tube body and steam enclosure to enclose a buffer channel, this technical solution utilizes the tube body to direct steam from the lower steam conduit or steam generation chamber into the upper steam conduit or steam chamber. The first baffles can be extended in a suitable direction as needed to block the gap between the tube body and the steam enclosure. This not only saves material costs but also reduces manufacturing difficulty.

[0018] 3. The first baffle partially blocks the gap, forming a gap between the first baffle and the steaming enclosure, which then forms a steam hole. This design creates a gap between the first baffle and the steaming enclosure. When the steaming enclosure and the steam duct are independently machined and assembled, the steaming enclosure can be smoothly and effortlessly fitted over the outside of the steam duct, avoiding contact and friction between the two during assembly, thereby reducing the difficulty of assembling the steam duct and steaming enclosure. Furthermore, using the gap to form the steam hole eliminates the need for separate machining of the steam hole, further simplifying product manufacturing.

[0019] 4. The first baffle blocks all gaps, and the steam holes are small holes set in the baffle. This design allows the first baffle to support the steamer enclosure and prevent it from sinking and deforming inward.

[0020] 5. The top of the steam duct is connected to the juice tray. The topmost juice tray is fixedly connected to a support tube extending downward. The steam duct connected to the topmost juice tray is the upper steam duct. The support tube and the upper steam duct are arranged symmetrically about the center of the topmost juice tray, and the bottom surface of the support tube is flush with the bottom surface of the upper steam duct. Because the topmost juice tray is connected to only one steam duct, when the topmost juice tray is removed, it cannot be stably placed on the single steam duct. By designing the support tube, the support tube and the upper steam duct can cooperate to support the topmost juice tray, allowing it to be placed more stably on the countertop.

[0021] 6. The inner wall of the steamer enclosure is equipped with anti-aliasing ribs that avoid the steam duct. The support tube is equipped with an anti-aliasing baffle. The anti-aliasing ribs and baffles prevent the steamer enclosure from being assembled with the adjacent upper juice tray. This design prevents users from installing the steamer enclosure and the adjacent upper juice tray upside down, ensuring that the steamer enclosure and the adjacent upper juice tray have only one relative position.

[0022] 7. Two vertically extending second baffles are installed on the inner side of the steam enclosure. The first steam outlet is located between the two second baffles. The portion of the steam enclosure between the two second baffles, the two second baffles, and the steam conduit together form a buffer channel. This design not only enhances the structural strength of the steam enclosure and prevents deformation, but also simplifies the structure of the steam conduit, thereby reducing the difficulty of manufacturing the steam conduit.

[0023] 8. The steam inlet is located on the other side opposite to the buffer channel; and / or, the steam inlet is arranged near the bottom of the steam chamber, and the first steam outlet is arranged near the top of the steam enclosure. This design can prevent the steam inlet from being arranged near the buffer channel, which causes the steam entering the steam chamber to be discharged directly into the buffer channel. In other words, it extends the path of the steam flowing from the steam inlet to the first steam outlet, so that the steam entering the steam chamber must pass through the entire steam chamber before entering the buffer channel and being discharged from the first steam outlet. This ensures that the steam can fill the entire steam chamber to achieve uniform heating of the food, thereby improving the utilization rate of the steam. At the same time, it also increases the residence time of the steam after entering the buffer channel 4, so that the steam is further decelerated and then slowly discharged from the first steam outlet, thereby avoiding the risk of scalding the user due to excessive steam exhaust.

[0024] 9. The steam passage also includes a steam pipe that runs through the juice tray. The lower end of the steam pipe is sleeved around the outer side of the steam pipe in the lower juice tray, while the upper end of the steam pipe is connected to the steam pipe in the upper juice tray. This design not only horizontally positions the steam pipe through the steam pipe to prevent it from shifting, thereby increasing the assembly reliability of the steam pipe, but also prevents steam in the steam pipe from leaking into the steam chamber as it flows into the steam pipe.

[0025] 10. The first steam outlet is located at a corner of the steam enclosure. The sidewalls of the steam enclosure on either side of the first steam outlet and the steam duct enclose the buffer channel. This design allows the steam duct to be located at the corner of the juice tray, reducing the space restrictions imposed by the steam duct on food placement. This allows the steam chamber to accommodate a wider range of food sizes, making the electric steamer suitable for a wider range of usage scenarios and improving its practicality. It also allows users to more flexibly arrange the layout of food within the steam chamber, fully utilizing the steam chamber and improving space utilization.

[0026] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

In this way, the wall of the buffer channel can block the steam to a certain extent, so that the steam first passes through the steam hole and is decelerated before entering the buffer channel. After diffusing in the buffer channel, it is further decelerated and finally slowly discharged from the first steam outlet, thereby avoiding the risk of scalding the user due to excessive steam exhaust and improving the user experience; finally, one of the steam ducts between the two adjacent juice receiving trays is set close to the first steam outlet, and is enclosed with the steaming enclosure to form a buffer channel. There is no need to set other baffle structures in the steaming enclosure to enclose the buffer channel with the steaming enclosure, thereby simplifying the structure of the steamer assembly.

[0045] Example 1

[0046] like Figures 1 to 11 As shown, the anti-flavor electric steamer in this embodiment includes a base 100 and a steamer assembly 200. The base 100 includes a pot body and a partition arranged in the pot body. The partition divides the interior of the pot body into multiple independent steam generating chambers 110. A heating device 120 is provided at the bottom of each steam generating chamber 110. The heating device 120 heats the water in the corresponding steam generating chamber 110 to form steam. The steamer assembly 200 includes multiple vertically spaced juice receiving trays 210, a steaming enclosure 220 arranged between two adjacent juice receiving trays 210, and a steaming cover 230 covered on the uppermost juice receiving tray 210. The steaming enclosure 220 and the two adjacent juice receiving trays 210 form a steaming chamber 201, and the uppermost juice receiving tray 210 and the steaming cover 230 form a steaming chamber 201, thereby allowing the steamer assembly 200 to have multiple vertically distributed and Independent steaming chambers 201, each steaming chamber 201 has a steam inlet, a first steam outlet 221 is provided on the steam enclosure 220, and a second steam outlet is provided on the steam cover 230, wherein the lowest layer of the juice receiving tray 210 is provided with a steam passage 211, wherein one of the steam generating chambers 110 is connected to the lowest layer of the steaming chamber 201 through the steam passage 211, and the remaining steam generating chambers 110 are each connected to the middle and upper layer steaming chambers through independent steam passages, that is, one steam generating chamber 110 is connected to one steaming chamber 201, and the middle and upper layer steaming chambers in this embodiment are other steaming chambers except the lowest layer steaming chamber. When the number of steam chambers is two, the middle and upper layer steaming chamber is the highest layer steaming chamber. When the number of steam chambers is greater than or equal to 3, the middle and upper layer steaming chambers include the highest layer steaming chamber and several middle layer steaming chambers located between the highest layer steaming chamber and the lowest layer steaming chamber.

[0047] The steam passage in this embodiment includes a steam conduit 300 provided between two adjacent juice receiving trays 210. All steam chambers 201 are arranged from high to low. The steam chamber 201 located at the top is the first steam chamber, and the steam chamber located at the bottom is the Nth steam chamber. The first steam chamber is connected to one of the steam generating chambers 110 through N-1 vertically connected steam conduits 300. The steam conduit 300 on the top is located in the second steam chamber and connected to the first steam chamber. The N-1 steam conduits 300 are vertically connected to form a steam passage. Only one steam conduit 300 in the steam passage is provided between two adjacent juice receiving trays 210. The second steam chamber is connected to one of the steam generating chambers 110 through N-2 vertically connected steam chamber conduits. The steam conduit 300 on the top is located in the third steam chamber and connected to the second steam chamber. The N-2 steam conduits 300 are vertically connected to form a steam passage. Only one steam conduit 300 in the steam passage is provided between two adjacent juice receiving trays 210, and so on. It should be noted that when the number of steaming chambers is greater than or equal to 3, except that there is no steam conduit in the first steaming chamber and there is only one steam conduit 300 in the second steaming chamber, there are at least two steam conduits 300 in the remaining steaming chambers 201.

[0048] In this embodiment, one of the steam ducts 300 between two adjacent juice receiving trays 210 is arranged near the first steam outlet 221. The steam duct 300 and the wall portion of the steam enclosure 220 located around the first steam outlet 221 form a vertically extending buffer channel 400. The steam inlet is located outside the buffer channel 400, and the buffer channel 400 has a steam hole 410 that is connected to the steam chamber 201. In this way, the wall of the buffer channel 400 can block the steam to a certain extent, so that the steam in the steam chamber 201 is first decelerated through the steam hole 410 and then enters the buffer channel 400. After diffusing in the buffer channel 400, it is further decelerated and finally slowly discharged from the first steam outlet 221, thereby avoiding the risk of scalding the user due to excessive steam exhaust and improving the user experience; finally, one of the steam ducts 300 between the two adjacent juice receiving trays 210 is set close to the first steam outlet 221, and is enclosed with the steam enclosure 220 to form a buffer channel 400. There is no need to set other baffle structures in the steam enclosure 220 to enclose the buffer channel with the steam enclosure, thereby simplifying the structure of the steamer assembly 200.

[0049] In this embodiment, there are two steaming chambers 201, two juice receiving trays 210, and one steam enclosure 220 and one steam duct 300. The steam passage also includes a steam pipe 500 that passes through the juice receiving tray 210. The lower end of the steam duct 300 is connected to one of the steam generating chambers 110 through the steam pipe 500 on the lowest juice receiving tray 210, and the upper end of the steam duct 300 is connected to the uppermost steaming chamber 201 through the steam pipe 500 on the uppermost juice receiving tray 210.

[0050] The steam duct 300 includes a tube body 310 and two vertically extending first baffles 320. There is a gap between the tube body 310 and the steam enclosure 220. One vertical side of the first baffle 320 is connected to the tube body 310. The first baffle 320 extends toward the steam enclosure 220 to block at least part of the gap. After the two first baffles 320 are connected to the tube body 310, a V-shaped structure or a U-shaped structure is formed. The first steam outlet 221 is located between the two first baffles 320. As a result, the steam duct 300 and the wall portion of the steam enclosure 220 located around the first steam outlet 221 can be enclosed to form a vertically extending buffer channel 400. Compared with using the entire tube body 310 and the steam enclosure 220 to enclose a buffer channel, the present technical solution uses the tube body 310 to introduce steam from the steam generating chamber 110 below into the steam chamber 201 above, and the first baffle 320 can select a suitable extension direction as needed to block the gap between the tube body 310 and the steam enclosure 220, which not only saves material costs but also reduces processing difficulty.

[0051] Preferably, the first baffle 320 in this embodiment partially obstructs the gap, forming a gap between the other vertical side of the first baffle 320 and the steam enclosure 220. This gap forms the steam passage hole 410, and the gap size does not exceed 3 mm. This design facilitates smooth and effortless assembly of the steam enclosure 220 and the steam duct 300 when they are independently machined and assembled. This avoids contact and friction between the two during assembly, thereby reducing the difficulty of assembling the steam duct 300 and the steam enclosure 220. Furthermore, the use of the gap to form the steam passage hole 410 eliminates the need for separate machining and forming of the steam passage hole 410, further reducing the manufacturing difficulty of the product.

[0052] In this embodiment, the top of the steam conduit 300 is connected to the juice tray 210, specifically, the steam conduit 300 is connected to the topmost juice tray 210. A downwardly extending support tube 600 is fixedly connected to the topmost juice tray 210. The steam conduit 300 forms an upper steam conduit connected to the topmost juice tray 210. The support tube 600 and the upper steam conduit are centrally symmetrically arranged about the center of the topmost juice tray 210, and the bottom surface of the support tube 600 is flush with the bottom surface of the upper steam conduit 300. Because the topmost juice tray 210 is connected to only one steam conduit 300, when the topmost juice tray 210 is removed, it cannot be stably placed on the single steam conduit 300. However, the design of the support tube 600 allows the support tube 600 and the upper steam conduit to cooperate in supporting the topmost juice tray 210, allowing it to be placed more stably on a countertop.

[0053] like Figures 9 to 11As shown, since the support tube 600 and the upper steam duct are arranged in a centrally symmetrical manner about the center of the uppermost juice receiving tray 210, in order to prevent the support tube 600 and the steam duct 300 from being interchanged in position and unable to form a steam passage due to the reverse installation during assembly, in this embodiment, the inner wall of the steam enclosure 220 is provided with anti-mistake ribs 222, and the anti-mistake ribs 222 avoid the first baffle 320. The support tube 600 is provided with an anti-mistake baffle 610. When installed reversely, the anti-mistake ribs 222 and the anti-mistake baffle 610 interfere with each other and prevent the steam enclosure 220 from being assembled into place with the uppermost juice receiving tray 210. This design can prevent the user from installing the steam enclosure 220 and the uppermost juice receiving tray 210 reversely, so that the steam enclosure 220 and the uppermost juice receiving tray have only a unique relative position.

[0054] The anti-fouling rib 222 is located in the buffer channel 400 and blocks the steam hole 410. The projection of the anti-fouling rib 222 on the uppermost juice receiving tray 210 is located outside the projection of the first baffle 320 on the uppermost juice receiving tray 210. When the uppermost juice receiving tray 210 assembled with the support tube 600 and the steam conduit 300 is installed upside down (e.g. Figure 11 As shown in FIG, the projection of the anti-fouling rib 222 on the uppermost juice receiving tray 210 and the projection of the anti-fouling baffle 610 on the uppermost juice receiving tray 210 at least partially overlap, so that the anti-fouling rib 222 and the anti-fouling baffle 610 interfere with each other. In this embodiment, when the uppermost juice receiving tray 210 and the steaming enclosure 220 are assembled correctly (as shown in FIG, Figure 9 and Figure 10 As shown), a steam gap is provided between the anti-fouling rib 222 and the first baffle 320, and the steam gap is connected to the steam hole 410, so that the steam in the steam chamber 201 can pass through the steam hole 410 and the steam gap in sequence and enter the buffer channel 400, thereby further reducing the flow rate of the steam through the obstruction of the anti-fouling rib 222, so that the first steam outlet 221 can slowly discharge the steam.

[0055] It can be understood that in other embodiments of the present invention, the anti-fouling rib can also be located outside the buffer channel and block the steam hole. There is a steam gap between the anti-fouling rib and the first baffle that is connected to the steam hole. In this way, the steam in the steam chamber can enter the buffer channel through the steam gap and the steam hole in turn.

[0056] In this embodiment, the steam duct 300 is integrally formed with the juice receiving tray 210. This design eliminates the need for assembly of the steam duct 300 and the juice receiving tray 210, thereby simplifying the assembly process. Preferably, the steam duct 300 is integrally formed with the topmost juice receiving tray 210. During assembly, the edge of the topmost juice receiving tray 210 is simply placed on the steaming enclosure 220.

[0057] It is understandable that in other embodiments of the present invention, the steam conduit is fixedly connected to the adjacent upper juice receiving tray by screws.

[0058] It can be understood that in other embodiments of the present invention, the steaming enclosure and the uppermost juice collecting tray are detachably connected by screws. With such a design, the user can place the assembled steaming enclosure and juice collecting tray directly on the lower juice collecting tray during subsequent multiple uses, without having to assemble the steaming enclosure and juice collecting tray separately each time, thereby improving the user experience; finally, the steaming enclosure and juice collecting tray can also be disassembled to clean them separately to reduce the difficulty of cleaning.

[0059] It should be noted that the steam pipe 500 in this embodiment is a structure protruding from the bottom wall of the juice receiving tray 210. The lower end of the steam conduit 300 is sleeved outside the steam pipe 500 of the lower juice receiving tray, and the upper end of the steam conduit 300 is connected to the lower end of the steam pipe 500 of the upper juice receiving tray. This design not only horizontally positions the steam conduit 300 through the steam pipe 500 to prevent it from shifting, thereby increasing the assembly reliability of the steam conduit 300, but also prevents steam in the steam pipe 500 from leaking into the steam chamber 201 as it flows into the steam conduit 300. It also prevents soup in the juice receiving tray 210 from entering the steam pipe 500 and flowing into the steam generating chamber 110.

[0060] The bottom juice receiving tray 210 is provided with a boss 212 formed by an upward arch, and the above-mentioned steam passage 211 is provided in the boss 212. The steam inlet is provided on the boss 212 and connects the steam passage 211 and the steam chamber 201. The boss 212 and the steam passage pipe 500 on the bottom juice receiving tray 210 are symmetrical about the center of the bottom juice receiving tray 210. This allows the steam inlet to be located on the other side opposite to the buffer channel 400, thereby avoiding the steam inlet being located close to the buffer channel 400, which causes the steam entering the steam chamber 201 to directly enter the buffer channel 400 and be discharged. That is, the path of the steam from the steam inlet to the first steam outlet 221 is extended, so that the steam entering the steam chamber 201 must pass through the entire steam chamber 201 before entering the buffer channel 400 and being discharged from the first steam outlet 221, thereby ensuring that the steam can fill the entire steam chamber 201 to achieve uniform heating of the food, thereby improving the utilization rate of the steam. Secondly, the lower end of the support tube 600 is sleeved on the outside of the boss 212, and the position of the support tube 600 above the boss 212 is provided with an opening 601, so that the steam inlet is connected with the bottom steam chamber 201 through the opening 601. Such a design can further improve the installation reliability of the top juice receiving tray 210 by restricting the support tube 600.

[0061] Preferably, the steam inlet in this embodiment is located near the bottom of the steam chamber 201, while the first steam outlet 221 is located near the top of the steam enclosure 220. This design further extends the path of steam flowing from the steam inlet to the first steam outlet 221, allowing the steam to fill the entire steam chamber 201. It also increases the retention time of the steam after entering the buffer channel 400, allowing the steam to be further decelerated and then slowly discharged from the first steam outlet 221, thereby avoiding the risk of scalding the user due to excessive steam exhaust.

[0062] In this embodiment, the juice tray 210 is also provided with a steaming plate 240 for receiving food. This design allows food to be placed on the steaming plate 240, isolating the food from the juice in the juice tray 210 through the steaming plate 240, preventing the juice in the juice tray 210 from affecting the steaming effect of the electric steamer. The boss 212 and the steam pipe 500 extend through the bottommost steaming plate 240, so that the top surfaces of the boss 212 and the steam pipe 500 are both higher than the steaming plate 240, further preventing soup from entering the steam passage 211 and the steam pipe 500. Furthermore, the opening 601 is positioned higher than the lower end of the steam conduit 300. A bottom gap is defined between the lower end of the steam conduit 300 and the steaming plate 240. The height of the bottom gap does not exceed 3 mm, allowing steam in the steaming chamber 201 to slowly enter the buffer channel 400 through the bottom gap.

[0063] Finally, in this embodiment, the steam enclosure 220 has a rectangular cross-section with rounded corners. The first steam outlet 221 is located at a corner of the steam enclosure 220, and the steam duct 300 is located at a corner of the steam chamber 201, near the first steam outlet 221. The sidewalls of the steam enclosure 220 on either side of the first steam outlet 221, combined with the steam duct 300, form the aforementioned buffer channel 400. This design, by locating the steam duct 300 at the corners of the juice receiving tray 210, reduces the space restrictions imposed by the steam duct 300 on food placement. This allows the steam chamber 201 to accommodate a wider variety of food sizes, making the electric steamer suitable for a wider range of usage scenarios and improving its practicality. It also allows users to more flexibly arrange food within the steam chamber 201, fully utilizing the steam chamber 201 and improving the space utilization of the steam chamber 201.

[0064] It can be understood that in other embodiments of the present invention, when the top surface of the steam pipe is located below the steaming plate, a through hole is opened in the steaming plate corresponding to the steam duct, and the steam duct passes through the through hole and is connected to the steam pipe, so that the steaming plate can avoid the steam duct and be placed on the juice receiving tray.

[0065] It is understandable that in other embodiments of the present invention, the first steam outlet may also be provided on the side wall of the steam enclosure. In this case, the steam conduit and the side wall provided with the first steam outlet are combined to form a buffer channel.

[0066] It is understood that in other embodiments of the present invention, the first baffle blocks the entire gap, and the steam holes are small holes provided on the first baffle. This design allows the first baffle to support the steamer enclosure and prevent the steamer enclosure from deforming inward.

[0067] It is understandable that in other embodiments of the present invention, the steam inlet and the steam exhaust channel are respectively arranged near two adjacent side walls of the steam enclosure; or, the steam inlet and the steam exhaust channel are respectively arranged near two adjacent corners of the steam enclosure.

[0068] Example 2

[0069] like Figure 12 As shown, unlike the first embodiment, the steam conduit 300 in this embodiment comprises only the pipe body of the first embodiment. Two vertically extending second baffles 223 are provided on the inner side of the steam enclosure 220. The first steam outlet 221 is located between the two second baffles 223. The portion of the steam enclosure 220 between the two second baffles 223, the two second baffles 223, and the steam conduit 300 together form the aforementioned buffer channel 400. A gap exists between the second baffles 223 and the steam conduit 300, forming a steam passage 410. This design not only enhances the structural strength of the steam enclosure 220 and prevents deformation, but also simplifies the structure of the steam conduit 300, thereby reducing the difficulty of manufacturing the steam conduit 300.

[0070] It is understandable that in other embodiments of the present invention, the steam enclosure, the second baffle and the steam conduit are integrally formed, and in this case, the second baffle is provided with small holes, which form steam holes.

[0071] Example 3

[0072] like Figure 13 As shown, unlike the first and second embodiments, the steam duct 300 in this embodiment only includes a tube body, and the cross-sectional shape of the tube body is a V-shaped structure or a U-shaped structure. The tube body and the steam enclosure 220 are enclosed to form a buffer channel 400 connected to the first steam outlet 221, and there is a gap between the tube body and the steam enclosure 220, and the gap forms a steam hole 410.

[0073] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
