Description

Technical Field

[0001] This application relates to the field of cooking appliances technology, and in particular to a steaming appliance. Background Technology

[0002] In steaming appliances, a drip tray is usually provided above the steam generating chamber, and the drip tray has an air outlet that connects the steam generating chamber and the steaming chamber. The steam in the steam generating chamber can flow to the steaming chamber through the air outlet for steaming and cooking the food inside.

[0003] In related technologies, the steam vents on the drip tray are usually located in the middle of the drip tray. This results in less steam near the edge of the steaming cavity compared to the steam in the middle of the steaming cavity, leading to uneven steam distribution within the steaming cavity and affecting the cooking effect of the food. Utility Model Content

[0004] Therefore, it is necessary to provide a steaming appliance that improves the uniformity of steam distribution within the steaming chamber, thereby enhancing the cooking effect of the food.

[0005] A steaming appliance includes a base and a drip tray; the base includes a water tank and a heating plate disposed at the bottom of the water tank; the drip tray is supported on the base and located above the water tank, and the drip tray has a steam outlet in the area above the heating plate, the steam outlet having at least two spaced-apart steam outlet areas; wherein, a steam generating chamber is provided between the water tank and the drip tray, the steam outlet areas are connected to the steam generating chamber, and the portion of the steam outlet area projected vertically is located outside the projection of the heating plate vertically.

[0006] Understandably, because the vertical projection of the steam vent area is located outside the vertical projection of the heating plate, the vertical projection of the steam vent is larger than the vertical projection of the heating plate. This design increases the area available for the steam vent area on the drip tray, allowing for more vents and increasing the steam flow cross-section, thus facilitating more thorough and rapid steam delivery into the steaming chamber. Furthermore, it brings the steam vents closer to the edges of the drip tray, reducing the distance between the vents and the edges. This allows the steam flowing out of the vents to distribute more quickly to the edges of the steaming chamber, increasing the steam content there, ensuring a more even distribution of steam within the chamber, and preventing the food from being undercooked at the edges while overcooked in the center, ultimately improving the cooking results.

[0007] In some embodiments, each of the steam outlet zones is eccentrically positioned relative to the drip tray. This arrangement ensures that each steam outlet zone is located as close to the side as possible, further improving the uniform distribution of steam.

[0008] In some embodiments, the central axis of the air outlet area is positioned close to the edge of the heating plate.

[0009] This setup satisfies the eccentric setting of each steam outlet area relative to the juice receiving plate, while ensuring a relatively large distance difference between the steam outlet area and the center of the steaming chamber. This minimizes the concentration of steam in the central area, promotes a more uniform diffusion path for the steam, and ensures that the steam fills the entire steaming chamber as evenly as possible.

[0010] In some embodiments, the drip tray has a length direction, and there are two venting areas, namely a first venting area and a second venting area, which are arranged at intervals along the length direction; wherein, along the vertical direction, the projections of the first venting area and the second venting area on opposite sides along the length direction both protrude beyond the projection of the heating plate.

[0011] This setup, while allowing for a more dispersed arrangement of the two steam outlet areas, not only increases the amount of steam on the sides but also helps reduce the amount of steam concentrated in the center, further facilitating the uniform distribution of steam.

[0012] In some embodiments, the air outlet has a first edge and a second edge that are arranged opposite to and spaced apart along the length direction, the first air outlet area is disposed near the first edge, and the second air outlet area is disposed near the second edge; along the length direction, there is a first distance L1 between the central axis of the first air outlet area and the central axis of the second air outlet area, a second distance L2 between the central axis of the first air outlet area and the first edge, and a third distance L3 between the central axis of the second air outlet area and the second edge, then satisfying: L1 > L2 and L1 > L3.

[0013] This setup ensures that the first and second air outlet areas are positioned as close as possible to their respective short edges, further reducing the distance between the air outlet areas and the short edges, which is more conducive to the uniform distribution of steam on the sides of the steam chamber.

[0014] In some embodiments, the drip tray has a length direction and a width direction, and at least two of the air outlet areas are spaced apart along the length direction; a first baffle is provided protruding upward inside the water tank, the first baffle surrounding the outer periphery of the heating plate and the air outlet; the first baffle includes two long axis sides arranged opposite to each other and spaced apart along the length direction and two short axis sides arranged opposite to each other and spaced apart along the width direction, the long axis sides and the short axis sides are connected, and at least one of the two short axis sides is tangent to the edge of the heating plate.

[0015] This setup ensures that each air outlet area is located within the space corresponding to the steam generation chamber, and also ensures that the cross-section of the steam generation chamber is small, which is beneficial for the heating plate to heat up and quickly boil to generate steam.

[0016] In some embodiments, the long axis side is arc-shaped, and the long axis side and the short axis side transition smoothly. This helps to reduce cleaning dead spots and facilitates cleaning.

[0017] In some embodiments, the drip tray has a boss at the upper center of the heating plate, the boss protrudes upward, and the air outlet is located on the boss.

[0018] This design not only ensures that the drip tray has ample space to collect the broth and residue produced during the steaming process, but also reduces the risk of interference with and blockage of the steam venting area.

[0019] In some embodiments, the drip tray is provided with a second baffle that protrudes downward, and the second baffle surrounds the outer periphery of the boss and the heating plate.

[0020] This setup ensures that the steam outlet is located within the steam generation chamber corresponding to the heating plate, and while maintaining a wide steam outlet range, it also ensures that the drip tray has sufficient load-bearing area.

[0021] In some embodiments, the protrusion height of the boss is greater than or equal to 10 mm.

[0022] This design ensures that the drip tray has sufficient volume to hold the soup and residue, while maintaining unobstructed airflow in the steam vent area, allowing steam to quickly and fully diffuse into the steaming chamber.

[0023] In some embodiments, the air outlet area includes a central air outlet and a plurality of side air outlets, the plurality of side air outlets being arranged at circumferential intervals around the central air outlet on the outer periphery of the central air outlet, and the plurality of side air outlets being arranged in a divergent manner.

[0024] This not only facilitates the uniform diffusion of steam in multiple directions but also maintains a large flow cross-section.

[0025] In some embodiments, the inner bottom wall of the water tank is provided with a first baffle rib protruding upwards, and the lower surface of the drip tray is provided with a second baffle rib protruding downwards. The second baffle rib surrounds the outer periphery of the first baffle rib, and the ends of the second baffle rib and the ends of the first baffle rib have overlapping areas in the vertical direction, and together define the steam generating chamber.

[0026] Understandably, using the first and second baffles together to define the steam generation chamber facilitates more efficient heating and increases the steam output speed. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0039] In related technologies, a drip tray is typically placed above the steam generating chamber. This tray is primarily used to collect the broth, condensate, and food residue that separates during steaming. The drip tray has an vent connecting the steam generating chamber and the steaming chamber, and this vent is usually located in the center of the tray. Steam generated in the steam generating chamber is transported to the steaming chamber through the vent for cooking the food inside. Because the vent is located in the center, the steam flowing out needs to diffuse from the center to the sides of the steaming chamber. This results in a significantly lower amount of steam at the sides compared to the center, meaning the steam distribution within the steaming chamber is uneven. The center of the steaming chamber heats up faster than the edges, leading to the food being undercooked at the edges while overcooked in the center, thus affecting the cooking results.

[0040] In view of this, one embodiment of this application provides a steaming appliance that can improve the uniformity of steam distribution within the steaming chamber, especially ensuring sufficient steam near the edge of the steaming chamber, thereby improving the cooking effect of the food. The steaming appliance is described in detail below.

[0041] Please see Figures 1 to 4 In some embodiments, the steaming appliance includes a base 10 and a drip tray 20 supported on the base 10. The base 10 includes a water tank 11 and a heating plate 12 disposed at the bottom of the water tank 11. The drip tray 20 is located above the water tank 11, and the drip tray 20 has a steam vent 21 in the area above the heating plate 12. The steam vent 21 has at least two spaced-apart steam venting areas 211. A steam generating chamber 1001 is provided between the water tank 11 and the drip tray 20. The steam venting areas 211 are connected to the steam generating chamber 1001, and the portion of the steam venting area 211 projected vertically is located outside the projection of the heating plate 12 vertically.

[0042] It should be noted in advance that, if Figure 1 As shown, the steaming apparatus also includes a steaming rack 40 and a pot lid 50. There can be one steaming rack 40 or at least two. When there is one steaming rack 40, its bottom is supported by the edge of the drip tray 20, and the pot lid 50 is placed on top of the steaming rack 40, together forming the steaming cavity 1002. When there are at least two steaming racks 40, they are stacked vertically, with a support frame between any two adjacent steaming racks 40, and the pot lid 50 is placed on top of the highest steaming rack 40. Of course, the steaming rack 40 can also be a steamer basket. This is only an example.

[0043] Among them, Figure 1 and Figure 2 In the diagram, the vertical direction is the Z-axis direction, which is the up-down direction.

[0044] Understandably, the heating plate 12 heats the water in the steam generating chamber 1001, causing it to boil and generate steam as quickly as possible. Since the steam outlet area 211 is connected to the steam generating chamber 1001, the steam in the steam generating chamber 1001 can flow through the steam outlet area 211 to the side of the drip tray 20 opposite to the water tank 11. When the drip tray 20 supports the steam rack 40, this portion of the steam flowing out is equivalent to flowing into the steaming chamber 1002 for steaming and cooking the food. In this process, precisely because the portion of the steam outlet area 211 projected vertically is located outside the portion of the heating plate 12 projected vertically, it is equivalent to the vertical projection of the steam outlet 21 being larger than the vertical projection of the heating plate 12. This design, on the one hand, increases the area on the drip tray 20 used for setting the steam venting area 211 (i.e., the area of ​​the steam venting section 21), allowing for the creation of more steam venting areas 211, increasing the steam flow cross-section, and facilitating more thorough and rapid delivery of steam into the steaming chamber 1002; on the other hand, it causes the steam venting areas 211 to be distributed closer to the sides of the drip tray 20, reducing the distance between the steam venting areas 211 and the sides of the drip tray 20. Thus, the steam flowing out through the steam venting areas 211 can be distributed more quickly to the sides of the steaming chamber 1002, increasing the steam content on the sides of the steaming chamber 1002, ensuring that the steam is distributed as evenly as possible within the steaming chamber 1002, improving the problem of undercooked edges and overcooked centers, and enhancing the cooking effect.

[0045] like Figure 2 As shown, the vertical projection dimension of the heating plate 12 is D1, and the vertical projection dimension of the air outlet 21 is D2. Then D2 > D1, so as to ensure that part of the air outlet area 211 is located outside the heating plate 12.

[0046] Please see Figures 2 to 4 Furthermore, each venting zone 211 is eccentrically positioned relative to the drip tray 20, meaning the central axis of the venting zone 211 does not coincide with the central axis of the drip tray 20. This ensures that each venting zone 211 is positioned as close to the side as possible, minimizing the amount of steam flowing directly to the center. Steam can then diffuse towards the sides and center, ensuring uniform steam distribution within the steaming chamber 1002.

[0047] Please see Figures 2 to 4 Furthermore, the central axis of the venting area 211 is positioned close to the edge of the heating plate 12. In actual use, the heating plate 12 and the drip tray 20 are usually concentrically positioned, meaning the central axis of the heating plate 12 coincides with the central axis of the drip tray 20, and also coincides with the central axis of the steaming chamber 1002. Therefore, this arrangement satisfies both the eccentric positioning of each venting area 211 relative to the drip tray 20 and ensures a relatively large distance difference between the venting area 211 and the center of the steaming chamber 1002.

[0048] Understandably, the cross-sectional area for steam transport on the drip tray is usually not very large, as it is necessary to maintain the pressure within the steam generating chamber to facilitate rapid heating. Therefore, when the size of the steam outlet area 211 is small, its central axis is positioned closer to the edge of the heating plate 12, effectively increasing the distance between the steam outlet area 211 and the center of the steaming chamber 1002. This allows the steam, after being released from the steam outlet area 211, to flow more quickly to the sides of the steaming chamber 1002 and also to diffuse towards the center, promoting a more uniform diffusion path and ensuring the steam fills the entire chamber as evenly as possible. This arrangement minimizes the concentration of steam in a single area of ​​the steaming chamber 1002, especially the central area, thus reducing the risk of overcooking the food in the center. Furthermore, because the steam outlet area 211 is closer to the sides of the steaming chamber 1002, the steam reaches the sides more quickly, increasing the steam content in the side areas and mitigating the problem of undercooked food on the sides.

[0049] In practical use, especially when the steaming cavity is rectangular, the drip tray should also be rectangular in shape. In this case, the drip tray has both length and width directions. The drip tray includes two short edges arranged opposite each other along the length direction and two long edges arranged opposite each other along the width direction. If the drip tray only has a steam vent in the center, the distance between the two short edges and the steam vent is significantly greater than the distance between the two long edges and the steam vent. This results in a significantly lower amount of steam distributed at the short edges compared to the long edges, leading to uneven steam distribution around the edges of the steaming cavity and affecting the cooking results.

[0050] It should be noted in advance that the length direction of the juice receiving tray 20 is the X-axis direction, that is, the left and right direction; the width direction of the juice receiving tray 20 is the Y-axis direction, that is, the front and back direction.

[0051] Please combine Figures 2 to 5 In some embodiments, the venting section 21 has two venting areas 211, namely a first venting area 211a and a second venting area 211b. The first venting area 211a and the second venting area 211b are arranged at intervals along the length of the drip tray 20. In the vertical direction, the projections of the first venting area 211a and the second venting area 211b, on opposite sides along the length direction, both protrude beyond the projection of the heating plate 12; that is, the vertically opposite portions of the projections of the first venting area 211a and the second venting area 211b are located outside the vertically projected portion of the heating plate 12.

[0052] like Figure 4 and Figure 5As shown, the two short edges are designated as the first short edge 22a and the second short edge 22b, respectively. The first short edge 22a is located on the left side of the length direction, and the second short edge 22b is located on the right side of the length direction. The first venting region 211a is positioned close to the first short edge 22a, and the second venting region 211b is positioned close to the second short edge 22b. That is, both the first venting region 211a and the second venting region 211b are eccentrically positioned relative to the juice tray 20, thereby reducing the distance between the first venting region 211a and the first short edge 22a, and the distance between the second venting region 211b and the second short edge 22b. This facilitates the full diffusion of steam flowing out through the first venting region 211a and the second venting region 211b to the two short edges, improving the uniformity of steam distribution. In addition, the arrangement of two steam outlet areas 211 can maintain the structural strength of the drip tray 20 itself while ensuring a large steam flow cross section, and maintain the pressure of the steam generating chamber 1001 in a state that is conducive to rapid heating; moreover, this arrangement can maximize the distance between the two areas and eliminate the steam outlet area between them, thereby reducing the amount of steam concentrated in the central area and further contributing to the uniform distribution of steam.

[0053] A straight line parallel to the short edge and passing through the central axis of the drip tray 20 is used as the central reference line. The first venting area 211a and the second venting area 211b are respectively located on both sides of this central reference line along its length. The distance between the first venting area 211a and the first short edge 22a is the length of a straight line from the central axis of the first venting area 211a to the first short edge 22a and perpendicular to the first short edge 22a. The distance between the second venting area 211b and the second short edge 22b is the length of a straight line from the central axis of the second venting area 211b to the second short edge 22b and perpendicular to the second short edge 22b. Furthermore, for the rectangular drip tray 20, the intersection of the two diagonals is the center or middle of the drip tray 20, and the straight line passing through the center of the drip tray 20 is the central axis of the drip tray 20.

[0054] Please continue reading. Figures 2 to 4 Furthermore, the venting section 21 has a first edge 21a and a second edge 21b arranged opposite to each other and spaced apart along its length. The first venting region 211a is located near the first edge 21a, and the second venting region 211b is located near the second edge 21b. Along the length of the drip tray 20, there is a first distance L1 between the central axis of the first venting region 211a and the central axis of the second venting region 211b, a second distance L2 between the central axis of the first venting region 211a and the first edge 21a, and a third distance L3 between the central axis of the second venting region 211b and the second edge 21b. Therefore, L1 > L2 and L1 > L3.

[0055] Specifically, the first edge 21a is close to the first short edge 22a of the drip tray 20, and the second edge 21b is close to the second short edge 22b of the drip tray 20. This arrangement ensures that the first venting area 211a and the second venting area 211b are as close as possible to their respective short edges, further reducing the distance between the venting area 211 and the short edge, which is more conducive to the uniform distribution of steam on the sides of the steaming chamber 1002.

[0056] Understandably, given the arrangement of the two outlet regions 211, both regions will supply steam to the center. If the first distance L1 is small, there will still be a problem of steam concentrating as much as possible in the center of the steam chamber 1002. Therefore, the first distance L1 needs to be large to ensure that steam is sufficiently distributed along the sides of the steam chamber 1002, while also allowing the combined effect of the two outlet regions 211 in the center to maintain sufficient steam content. This further improves the uniform distribution of steam within the steam chamber 1002.

[0057] In some specific embodiments, the second spacing L2 and the third spacing L3 are the same. That is, the first venting region 211a and the second venting region 211b are spaced at the same distance from their respective short edges, meaning they are symmetrically positioned relative to the aforementioned central baseline, which is more conducive to the uniform distribution of steam on both sides of the steam chamber 1002 along its length.

[0058] Alternatively, the first spacing can be smaller than the second spacing, or the first spacing can be larger than the second spacing. The key is to improve the uniformity of steam distribution.

[0059] like Figure 4 and Figure 5 As shown, in some embodiments, the distance between each outlet region 211 and its long edge is the same. That is, the distance between the first outlet region 211a and each long edge is the same, and the distance between the second outlet region 211b and each long edge is the same. In this way, each outlet region 211 is kept as close to the center as possible in the width direction, ensuring uniform distribution of steam on both sides in the width direction.

[0060] like Figure 1 and Figure 2As shown, in some embodiments, the water tank 11 and / or the drip tray 20 are provided with baffles 30 surrounding the outer periphery of the heating plate 12 and the steam outlet 21. The water tank 11, the baffles 30, and the drip tray 20 together form a steam generating chamber 1001. It is understood that because the baffles 30 surround the outer periphery of the heating plate 12, the amount of water in the steam generating chamber 1001 can be kept relatively low, which is beneficial for the heating plate 12 to heat more efficiently and increase the steam outlet speed. Moreover, the baffles 30 also serve as heat insulation, reducing the impact of water in the water tank 11 located outside the heating plate 12 on the heating of the water in the steam generating chamber 1001, further improving heating efficiency.

[0061] The baffle 30 corresponding to the water tank 11 is the first baffle 31, and the baffle 30 corresponding to the juice receiving tray 20 is the second baffle 32.

[0062] In some embodiments, the inner bottom wall of the water tank 11 may be provided with a first baffle 31 protruding upwards, and the extended end of the first baffle 31 may be connected to the bottom of the drip tray 20. For example, the extended end of the first baffle 31 may abut against the drip tray 20; or, the bottom of the drip tray 20 may be provided with a slot, and the end of the first baffle 31 may be inserted into the slot; or, the first baffle 31 and the drip tray 20 may be engaged with each other, etc. As long as it can be ensured that when the drip tray 20 is supported on the base 10, the first baffle 31, the water tank 11 and the drip tray 20 together form a steam generating chamber 1001, ensuring that steam flows as fully as possible through the steam outlet area 211 to the steaming chamber 1002.

[0063] Alternatively, a second baffle 32 protrudes downward from the lower surface of the drip tray 20, and the extended end of the second baffle 32 is connected to the inner bottom wall of the water tank 11. The specific connection method is similar to the cooperation between the first baffle 31 and the drip tray 20 mentioned above. It is only necessary to ensure that the second baffle 32, the drip tray 20 and the water tank 11 form a steam generating chamber 1001 and ensure that the steam flows as fully as possible through the steam outlet area 211 to the steaming chamber 1002. It will not be described in detail here.

[0064] Please continue to combine Figure 1 , Figure 2 , Figure 3 and Figure 5In some specific embodiments, the inner bottom wall of the water tank 11 is provided with an upwardly protruding first baffle 31, and the lower surface of the drip tray 20 is provided with a downwardly protruding second baffle 32. The first baffle 31, the second baffle 32, the water tank 11, and the drip tray 20 together form a steam generating chamber 1001. The extended ends of the first baffle 31 and the second baffle 32 can abut, insert, or snap together, etc. Specific methods can be referred to the aforementioned cooperation between the first baffle 31 and the drip tray 20, which will not be repeated here. Alternatively, the first baffle 31 can extend into the range of the second baffle 32, that is, the second baffle 32 surrounds the outer periphery of the first baffle 31, so that the first baffle 31 and the second baffle 32 have an overlapping area in the vertical direction, as long as it satisfies the formation of the steam generating chamber 1001.

[0065] Furthermore, a sealing ring can be provided between the first baffle 31 and the second baffle 32 to maintain the airtightness of the steam generating chamber 1001, reduce steam leakage within the steam generating chamber 1001, and ensure that steam flows as fully as possible through at least two steam outlet areas 211 to the steaming chamber 1002. Of course, a sealing ring can also be provided between the first baffle 31 and the drip tray 20. Alternatively, a sealing ring can also be provided between the second baffle 32 and the water tank 11.

[0066] Please see Figures 3 to 5 In some embodiments, the first baffle 31 includes two long axis sides 301 arranged opposite to each other along the length direction and two short axis sides 302 arranged opposite to each other along the width direction and spaced apart. The long axis sides 301 and the short axis sides 302 are connected, and both short axis sides 302 are tangent to the edge of the heating plate 12.

[0067] In other words, because the two air outlet areas 211 protrude from opposite sides of the heating plate 12 along their length, the length of the first baffle 30 must at least meet the setting range of the air outlet areas 211 to ensure that each air outlet area 211 is located within the space corresponding to the steam generating chamber 1001. Therefore, both sides of the first baffle 31 protrude from the heating plate 12 along its length. At the same time, because the short axis side 302 of the first baffle 31 is tangent to the edge of the heating plate 12, it is equivalent to constraining the dimensions of both sides of the first baffle 31 along its width, thereby ensuring that the cross-section of the formed steam generating chamber 1001 is not too large and thus increases the heating load on the heating plate 12.

[0068] Understandably, if the cross-section of the steam generating chamber 1001 is too large, resulting in a large amount of water in the steam generating chamber 1001, it will take a long time to reach boiling point, affecting the steam output speed. Therefore, the configuration in this embodiment ensures that the cross-section of the steam generating chamber 1001 is small while maintaining the first steam output area 211a and the second steam output area 211b close to the short side edge. This keeps the water volume in the steam generating chamber 1001 relatively small, which is beneficial for the heating plate 12 to heat and quickly boil to generate steam.

[0069] Furthermore, the two major axis sides 301 are arranged in an arc shape, while the two minor axis sides 302 are arranged in a straight line. This arrangement ensures a smooth transition between the major axis sides 301 and the minor axis sides 302, reducing cleaning dead zones. Specifically, both major axis sides 301 can be semi-circular; or both major axis sides 301 can be semi-elliptical; or one major axis side 301 can be semi-circular and the other can be semi-elliptical. This is merely an example.

[0070] The shape of the second baffle 32 is adapted to the shape of the first baffle 31. Therefore, the second baffle 32 also includes two arc-shaped long axis sides 301 and two straight short axis sides 302.

[0071] Alternatively, the first baffle 31 and the second baffle 32 can be directly set to an ellipse shape.

[0072] like Figure 2 and Figure 4 As shown, in some specific embodiments, the vertical projection of the air outlet 21 is elongated, and the length direction of the air outlet 21 is the same as the length direction of the drip tray 20. The vertical projections of the first baffle 31 and the second baffle 32 correspond to the projection of the air outlet 21. This ensures that the entire air outlet 21 is located within the steam generating chamber 1001, facilitating the full diffusion of steam into the steaming chamber 1002. Figure 2 D2 in the figure represents the length of the air outlet 21, which is the distance between the first edge 21a and the second edge 21b along the length direction.

[0073] like Figure 3 As shown, in actual use, the first baffle 31 is provided with a water inlet 311 near the bottom wall of the water tank 11. The water inlet 311 connects the water tank 11 and the steam generating chamber 1001, and is used to guide water in the water tank 11 to the steam generating chamber 1001 to meet heating requirements. Multiple water inlets 311 are provided and arranged at intervals along the circumference of the first baffle 31. The diameter of the water inlets 311 is small to limit the flow rate and velocity, thereby maintaining a relatively low water volume in the steam generating chamber 1001, improving heating efficiency and steam output speed.

[0074] Please see Figure 1 , Figure 2 and Figure 4 In some embodiments, the drip tray 20 has a protrusion 24 at the upper center of the heating plate 12. The protrusion 24 protrudes upward, and the vent 21 is located on the protrusion 24. The second baffle 32 surrounds the outer periphery of the protrusion 24. That is, by using the protrusion 24, the vent 21 is essentially raised relative to the inner bottom wall of the drip tray 20, thereby isolating the vent area 211 from the area used to hold soup, residue, etc. This arrangement not only maintains sufficient space in the drip tray 20 to hold the soup, residue, etc. generated during the steaming process, but also reduces the risk of interference and blockage in the vent area 211. Moreover, this arrangement also reduces the height of the vent area 211 relative to the bottom of the steam rack 40, which is more conducive to the rapid flow of steam to the steaming chamber 1002 and its even distribution.

[0075] The upper surface of the drip tray 20 protrudes upward to form a boss 24, while the lower surface of the drip tray 20 is correspondingly recessed upward to form a cavity. This effectively increases the vertical height of the steam generating chamber 1001, making it easier for water droplets to settle due to gravity, thereby reducing the moisture carried in the steam and ensuring the steam temperature.

[0076] Furthermore, the protrusion height of the boss 24 is greater than or equal to 10mm.

[0077] Understandably, the height of the protrusion 24 should not be too small or too large. If it is too small, the height difference between the venting area 211 and the inner bottom wall of the drip tray 20 will not be significant enough. Since the overall area occupied by the venting part 21 is relatively large, the volume of soup and residue that the drip tray 20 can collect will be reduced, and the venting area 211 will easily become clogged. If it is too large, it will not only interfere with the placement of the steaming rack 40, but also cause the venting area 211 to become clogged due to the protrusion 24 being close to the steaming rack 40.

[0078] Therefore, in this embodiment, the protrusion height of the boss 24 is made to be greater than or equal to 10mm, for example, it can be 10mm, 15mm, 20mm, 25mm, etc., thereby ensuring that the venting area 211 is isolated from the bearing area. While ensuring that the drip tray 20 has sufficient volume to receive soup and residue, the venting area 211 is kept unobstructed, ensuring that steam can quickly and fully diffuse into the steaming chamber 1002.

[0079] Furthermore, the rounded corners of the protrusion 24 facilitate the flow of broth to the upper surface of the drip tray 20. The outer periphery of the protrusion 24 can also be beveled to improve the flow guiding effect.

[0080] In some embodiments, the second baffle 32 surrounds the outer periphery of the boss 24. It is understood that since the second baffle 32 defines the steam generating chamber 1001 and the air outlet 21 is located on the boss 24, the enclosure of the second baffle 32 relative to the boss 24 ensures that the air outlet 21 is within the steam generating chamber 1001, which is equivalent to limiting the planar range of the boss 24. This ensures that the drip tray 20 has sufficient bearing area while maintaining a relatively wide range for the air outlet 21. The vertical projection profile of the junction between the boss 24 and the upper surface of the drip tray 20 can coincide with the vertical projection profile of the first baffle 31. Alternatively, the second baffle 32 can be tangent to the boss 24. The key is to ensure smooth and rapid airflow in the air outlet area 211.

[0081] Please see Figure 2 , Figure 4 and Figure 5 In some embodiments, the venting area 211 includes a plurality of spaced-apart vents 2111, each vent 2111 penetrating the venting portion 21 on the drip tray 20 to connect to the steam generating chamber 1001. The arrangement of the plurality of vents 2111 ensures the flow cross-section of the venting area 211 and improves the venting speed and venting volume.

[0082] Furthermore, the multiple vents 2111 are a central vent 2111a and side vents 2111b, with the central axis of the central vent 2111a serving as the central axis of the venting region 211. Multiple side vents 2111b are provided and arranged at intervals along the circumference of the central vent 2111a. The multiple side vents 2111b are arranged in a divergent pattern, with the diameter of each side vent 2111b gradually increasing from the inside to the outside along the radial direction of the central vent 2111a. This not only facilitates uniform steam diffusion in multiple directions but also maintains a large flow cross-section.

[0083] In some specific embodiments, each side vent 2111b is arc-shaped, and the arcs bend in the same direction. This arrangement reduces the flow resistance of steam and facilitates smooth steam passage. The side vent 2111b has an arc-shaped inner side and an arc-shaped outer side, with the outer side positioned on an arc tangent to the central vent 2111a. This arrangement causes a certain centrifugal force in the steam flow, further promoting uniform and rapid diffusion of steam to the outer periphery of the venting area 211.

[0084] In other embodiments, when the steaming chamber 1002 is circular, the drip tray 20 is also circular. In this case, the vertical projection of the steam outlet 21 is circular, and the steam outlet 21, heating plate 12, and drip tray 20 are coaxially arranged. Multiple steam outlet areas 211 are arranged circumferentially around the steam outlet 21 and offset relative to the center of the drip tray 20. The distance between each steam outlet area 211 and the edge of the drip tray 20 is substantially the same to ensure that steam can diffuse evenly and quickly to the sides of the steaming chamber 1002. At least three steam outlet areas 211 can be provided. However, the number of steam outlet areas 211 should not be excessive, otherwise it will affect the structural strength of the drip tray 20 and the pressure within the steam generating chamber 1001.

[0085] Furthermore, when the steaming chamber 1002 is square, the drip tray 20 and the steam outlet 21 are also square to match it. Each edge of the steam outlet 21 is provided with a corresponding steam outlet area 211, which not only ensures that the steam outlet area 211 is offset from the center of the drip tray 20, but also reduces the distance between the steam outlet area 211 and the edge, thereby improving the uniformity of steam distribution in the steaming chamber 1002.

[0086] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application.
