Abstract
Description
Technical Field
[0001] This application relates to the field of cooking appliance technology, and more specifically, to a flow guiding component and a cooking appliance. Background Technology
[0002] In related technologies, cooking appliances lack a steam guiding structure. When the appliance is cooking, the steam generated by the steam generator directly enters the cooking chamber. The high speed of the steam entering the chamber causes it to be entrained and mixed with the existing air. This mixture makes it difficult to effectively expel the air from the cooking chamber, resulting in a high oxygen content. This significantly affects cooking performance and the lifespan of the appliance. Utility Model Content
[0003] This application aims to address at least one of the technical problems existing in the prior art or related technologies.
[0004] Therefore, the first aspect of this application proposes a flow guiding component.
[0005] The second aspect of this application proposes a cooking utensil.
[0006] In view of the above, the first aspect of this application proposes a flow guiding assembly, comprising: a flow divider having a first chamber inside, a first inlet and a plurality of first outlets on the flow divider, the first inlet and the first outlets both being connected to the first chamber; and a flow guiding structure having a second chamber inside, a plurality of second inlets and second outlets on the flow guiding structure, each first outlet being connected to the second chamber through a second inlet, and the second outlet being connected to the second chamber.
[0007] The flow guiding component provided in this application includes a flow divider and a flow guiding structure.
[0008] The distributor has a first chamber, a first inlet, and multiple first outlets. Any one of the multiple first outlets and the first inlet is connected to the first chamber. The first inlet is used to connect to the steam generator of a cooking appliance.
[0009] The flow guiding structure includes a second chamber and multiple second inlets and outlets. Each first outlet connects to a second chamber via a second inlet, and the second outlet is also connected to the second chamber. The second outlets are used to supply steam to the cooking chamber of the cooking appliance.
[0010] A flow guiding assembly is used in a cooking appliance, which has a cooking chamber. A steam generator is connected to a first inlet of a distributor, and a second outlet of the flow guiding assembly is connected to the cooking chamber. When the cooking appliance is in operation, the steam generated by the steam generator flows into the cooking chamber via the flow guiding assembly. Specifically, the steam generated by the steam generator enters a first chamber through the first inlet, then simultaneously flows through multiple first outlets to multiple second inlets, then flows into a second chamber, and finally flows into the cooking chamber through the second outlet.
[0011] It is understandable that the cross-sectional area of the first inlet is smaller than that of the first chamber. Steam enters the first chamber with a larger cross-sectional area through the first inlet with a smaller cross-sectional area. The larger volume of the first chamber can provide a buffer space for the steam. When the steam flows in at high speed from the first inlet, the expansion of the chamber volume will reduce the steam velocity and alleviate pressure fluctuations. The steam will diffuse to the surrounding low-pressure areas and flow to multiple second inlets simultaneously through multiple first outlets.
[0012] Understandably, steam flows into the second chamber simultaneously through multiple second inlets, meaning the steam is diverted by a distributor before entering the second chamber. Due to the increased volume of the second chamber, the steam velocity and pressure are further reduced, and it finally enters the top of the cooking chamber at a low speed through the second outlet. Because of the density difference between the high-temperature steam and the air inside the cooking chamber, the continuously flowing steam accumulates at the top of the cooking chamber, allowing the air below to be effectively discharged through the exhaust port. Since the steam does not mix with the air inside the cooking chamber, the air can be quickly expelled, rapidly reducing the oxygen content inside the chamber and achieving an anaerobic steaming effect. Anaerobic steaming reduces the contact between food and oxygen, optimizing the cooking effect in terms of nutrition, taste, and safety. It helps retain nutrients, reduces oxidation loss, improves the color and taste of food, reduces the formation of harmful substances, and slows down the oxidation rate of cooking utensils, extending their lifespan and reducing the difficulty of cleaning.
[0013] In addition, there are multiple first outlets and multiple second inlets. Each first outlet is connected to the second chamber through a second inlet. In this way, steam can flow into the second chamber from multiple directions and multiple positions at the same time, so that different areas in the second chamber are effectively filled with steam, providing structural support for the subsequent steam to enter the cooking chamber in a low-speed laminar flow manner through the second outlet.
[0014] In some technical solutions, optionally, the first inlet is located on the first side of the splitter, and a plurality of first outlets are located on the second side of the splitter, wherein the first side and the second side of the splitter are adjacent sides of the splitter.
[0015] In this technical solution, the arrangement positions of the first entrance and multiple first exits are further defined.
[0016] The first inlet is located on the first side of the splitter, and multiple first outlets are located on the second side of the splitter. That is, the first inlet and the first outlet are located on different sides of the splitter. Specifically, the first inlet and the first outlet are located on adjacent sides of the splitter.
[0017] In this way, the steam entering the first chamber through the first inlet will not flow directly to the multiple first outlets. Instead, it will be deflected upon impacting the chamber wall and then flow through the flow guide structure via the multiple first outlets. It can be understood that the relatively high-velocity steam, after impacting the chamber wall, can flow to the multiple first outlets at a relatively uniform flow rate. This helps to balance the velocity and flow rate of the steam flowing to the multiple second inlets.
[0018] In some technical solutions, optionally, the diverter includes: a first end wall, a first inlet located on the first end wall; a second end wall, at least a portion of which is a dish-shaped wall; and a circumferential wall connected between the first end wall and the second end wall, the first end wall, the second end wall, and the circumferential wall enclosing a first chamber, and a plurality of first outlets located on the circumferential wall.
[0019] In this technical solution, the distributor includes a first end wall, a second end wall, and a circumferential wall.
[0020] The first end wall and the second end wall are arranged opposite each other and spaced apart. A circumferential wall is connected between the first end wall and the second end wall. The first end wall, the second end wall and the circumferential wall enclose the first chamber.
[0021] The first inlet is located on the first end wall, and multiple first outlets are located on the circumferential wall, which can meet the usage requirements of the first inlet and the first outlet being located on adjacent sides of the splitter.
[0022] Specifically, the steam entering the first chamber through the first inlet at the first end wall will flow to the second end wall. Since at least a portion of the second end wall is a dish-shaped wall, the steam will bend after impacting the second end wall and flow evenly to the multiple first outlets of the circumferential wall. In other words, the steam will flow to the multiple first outlets at a uniform flow rate after impacting the second end wall.
[0023] In some technical solutions, optionally, the distributor is also provided with a flow guide section, which connects to the first chamber.
[0024] In this technical solution, the structure of the distributor is further defined. The distributor is also provided with a guide section, which is connected to the first chamber. The guide section is used to guide the condensate accumulated in the first chamber out of the distributor, thereby reducing the amount of condensate flowing into the guide structure under the drive of steam. This provides structural support to prevent condensate from dripping into the food in the cooking cavity. At the same time, this structural design can also reduce the difficulty of cleaning the cooking cavity.
[0025] In some technical solutions, optionally, the first inlet, the first outlet, and the guide section all extend outward from the outer surface of the splitter.
[0026] In this technical solution, the first inlet, the first outlet, and the guide section all extend outward from the outer surface of the distributor. That is, the first inlet extends outward from the outer surface of the distributor, the first outlet extends outward from the outer surface of the distributor, and the guide section extends outward from the outer surface of the distributor. Alternatively, it can be said that the first inlet, the first outlet, and the guide section all protrude from the outer surface of the distributor. This provides structural support for the connection between the first flexible pipe and the first inlet and the steam generator, and for the connection between the second flexible pipe and the first outlet and the second inlet, reducing the assembly difficulty of the guide component and facilitating its assembly and disassembly.
[0027] At the same time, this configuration facilitates precise control of steam flow. If the first inlet, the first outlet, and the guide section are all located inside the distributor, it will result in a complex internal structure of the distributor, which is prone to dead zones and is not conducive to steam flow.
[0028] In some technical solutions, optionally, the sum of the cross-sectional areas of the multiple second inlets is less than the cross-sectional area of the second outlet.
[0029] In this technical solution, the cooperative structure of multiple second inlets and second outlets is further defined such that the sum of the cross-sectional areas of the multiple second inlets is less than the cross-sectional area of the second outlet.
[0030] This increases the area of the steam guide component that directs steam into the cooking cavity, further reducing the steam flow rate and achieving a relatively large steam output, which helps improve the uniformity of steam flowing into the cooking cavity from the top.
[0031] In some technical solutions, optionally, at least one baffle is provided in the second outlet section, and the inner surface of the second outlet section and at least one baffle enclose multiple channels; the channels have a first inlet end and a first outlet end, the first inlet end connects the second chamber and the first outlet end, and the flow cross-sectional area of the first inlet end is smaller than the flow cross-sectional area of the first outlet end.
[0032] In this technical solution, the structure of the second outlet is further defined such that at least one partition is provided inside the second outlet. The inner surface of the second outlet and the at least one partition enclose multiple channels. That is, at least one partition divides the internal space of the second outlet into multiple channels, each channel connecting to the second chamber.
[0033] Steam flows simultaneously into multiple channels through the second chamber. The cross-sectional area of the first inlet is smaller than that of the first outlet. The change in the cross-sectional area at the first inlet and outlet alters the steam velocity, thus reducing it. Furthermore, this change in cross-sectional area also diffuses the concentrated steam flow over a wider area, for example, from the center of the channel outwards. This avoids dead zones, reduces localized high-speed turbulence, and allows the steam to be evenly distributed throughout the cooking chamber at a low-speed laminar flow through the second outlet, improving the cooking efficiency of the appliance.
[0034] In addition, the combination of multiple channels with varying cross-sectional areas can enhance the effect of reducing steam velocity and improving the uniform distribution of steam.
[0035] In some technical solutions, the second outlet section may optionally have a second inlet end and a second outlet end, the second inlet end being connected to the second outlet end and the second chamber, and the flow cross-sectional area of the second inlet end being smaller than the flow cross-sectional area of the second outlet end.
[0036] In this technical solution, the structure of the second outlet section is further defined. The second outlet section has a second inlet end and a second outlet end, and the second inlet end is connected to the second outlet end and the second chamber.
[0037] Steam flows through the second chamber to the second inlet and then into the cooking chamber through the second outlet. The cross-sectional area of the second inlet is smaller than that of the second outlet. This change in the cross-sectional area alters the steam velocity, reducing it. Furthermore, this change in cross-sectional area also helps to diffuse the concentrated steam flow over a wider area, such as from the center of the second outlet outwards. This avoids dead zones, reduces localized high-speed turbulence, and allows the steam to be evenly distributed in the cooking chamber at a low speed through the second outlet, thus improving the cooking efficiency of the appliance.
[0038] In some technical solutions, optionally, multiple second inlets are located on the first side of the flow guiding structure, and the second outlet is located on the second side of the flow guiding structure, with the first side and the second side of the flow guiding structure being adjacent sides of the flow guiding structure.
[0039] In this technical solution, the arrangement positions of multiple second inlets and second outlets are further defined.
[0040] Multiple second inlets are located on the first side of the flow guide structure, and second outlets are located on the second side of the flow guide structure. That is, the second inlets and second outlets are located on different sides of the flow guide structure. Specifically, the second inlets and second outlets are located on adjacent sides of the flow guide structure.
[0041] In this way, the steam entering the second chamber through multiple second inlets will not flow directly to the second outlet. Instead, it will be deflected upon impacting the walls of the second chamber and then flow into the cooking chamber through the second outlet. It is understandable that the relatively high-velocity steam, after impacting the walls of the second chamber, can flow towards the second outlet at a relatively uniform flow rate. This helps to balance the velocity and flow rate of the steam entering the cooking chamber.
[0042] In some technical solutions, optionally, the flow guiding structure includes: a connecting plate, with multiple second inlets located on the same side of the connecting plate; a flow guiding channel connected to the side of the connecting plate away from the second inlets, the flow guiding channel communicating with the second inlets; and a cover plate covering the flow guiding channel, with the second outlet located on the cover plate; wherein the connecting plate, the flow guiding channel, and the cover plate enclose a second chamber.
[0043] In this technical solution, the composition of the flow guiding structure is further defined.
[0044] The flow guiding structure includes a connecting plate, a flow guiding channel, and a cover plate.
[0045] Multiple second inlets are located on the same side of the connecting plate, and the guide channel is connected to the side of the connecting plate opposite to the second inlets. That is, the second inlets and the guide channel are located on opposite sides of the connecting plate. The guide channel communicates with the second inlets.
[0046] Furthermore, a cover plate is placed on the guide channel, and a second outlet is located on the cover plate. The connecting plate, the guide channel, and the cover plate enclose the second chamber. That is, the steam flowing into the second chamber through the multiple second inlets on the connecting plate will flow into the guide channel. After impacting the channel wall, the steam will be deflected by the channel wall and flow to the second outlet of the cover plate.
[0047] Understandably, the cover plate is placed over the guide channel, and the connecting plate is located between the second inlet and the guide channel. That is, the second inlet is located on the side of the guide channel, and the second outlet is located above the guide channel. This arrangement provides structural support for the downward flow of steam from the top of the cooking chamber. Furthermore, because the second inlet is located on the side of the guide channel, the space at the top of the cooking appliance is relatively small, while the space on the outer side of the appliance is relatively large. Therefore, this arrangement ensures that the second inlet does not occupy the space at the top of the cooking appliance, effectively utilizing the existing installation space for installation and positioning.
[0048] In some technical solutions, the channel wall may optionally include an inclined wall, which is opposite to and spaced apart from the connecting plate; the distance between the inclined wall and the connecting plate gradually increases along the direction from the channel to the cover plate.
[0049] In this technical solution, the structure of the flow guide channel is further defined.
[0050] The channel wall includes inclined walls, which are opposite to and spaced apart from the connecting plate.
[0051] The extension direction of the inclined wall is defined; specifically, the distance between the inclined wall and the connecting plate gradually increases along the direction from the guide channel to the cover plate. The inclined wall has a guiding function, which can guide the steam to move upward along the extension direction of the inclined wall to the cover plate. That is, the inclined wall can guide the steam to flow in an orderly manner to the second outlet of the cover plate, providing structural support for the steam to flow into the cooking cavity through the second outlet.
[0052] In some technical solutions, optionally, the flow channel has a first opening, a second opening, and a surrounding edge, the surrounding edge is arranged around the first opening and abuts against the connecting plate, the second opening connects the second outlet and the first opening, and the first opening connects each second inlet; the cover plate is provided with a slot, and the side of the flow channel with the second opening is inserted into the slot.
[0053] In this technical solution, the structure of the flow guide channel is further defined.
[0054] The guide channel has a first opening and a second opening. Each second inlet is connected to the second opening through the first opening, and the second opening is connected to the second outlet. Specifically, steam flows into the first opening through multiple second inlets, and then flows into the second outlet through the second opening.
[0055] The guide channel also has a surrounding edge that surrounds the first opening and abuts against the connecting plate. This design increases the contact area between the guide channel and the connecting plate, facilitating their assembly. For example, the surrounding edge and the connecting plate are bonded together to ensure airtightness at the connection point, preventing steam leakage through this connection.
[0056] The cover plate is provided with a slot, and the side of the guide channel with the second opening is inserted into the slot. That is, the side of the guide channel with the second opening is inserted into the slot. This setting increases the mating area between the cover plate and the guide channel, and a part of the guide channel will be inserted into the slot. The slot has the function of limiting the guide channel, which can ensure the relative displacement between the cover plate and the guide channel, and is conducive to improving the stability and reliability of the guide structure assembly.
[0057] In some technical solutions, the flow guiding assembly may optionally include: a steam generator; a first flexible tube connecting the steam generator and a first inlet; and a plurality of second flexible tubes, each of the first outlets being connected to a second inlet via a second flexible tube.
[0058] In this technical solution, the structure of the flow guiding component is further defined.
[0059] The flow guiding assembly also includes a steam generator, a first flexible tube, and multiple second flexible tubes.
[0060] Each first outlet is connected to a second inlet via a second flexible tube.
[0061] The first flexible tube and multiple second flexible tubes work together to ensure the flow path of the steam.
[0062] Understandably, the steam generator produces steam, which flows through the first flexible pipe to the distributor, and after being split by the distributor, it flows through multiple second flexible pipes to the flow guide structure.
[0063] It is understandable that both the first and second flexible tubes are flexible, and their shapes are variable. The shapes of the first and second flexible tubes can be adaptively adjusted according to the specific locations of the distributor, guide structure, and housing to ensure the steam flow path and meet the needs of various cooking appliances.
[0064] The second aspect of this application provides a cooking appliance, including: a flow guide component as described in the first aspect.
[0065] The cooking appliance provided in this application includes the flow guiding component as described in the first aspect, and therefore has all the beneficial effects of the aforementioned flow guiding component, which will not be described in detail here.
[0066] In some technical solutions, the cooking appliance may optionally include: a housing, the inner surface of which encloses a cooking cavity, and a second outlet communicating with the cooking cavity; and a cover that covers the housing; wherein at least a portion of the flow guiding structure, the steam generator and the flow divider of the flow guiding assembly are located between the housing and the cover.
[0067] In this technical solution, the structure of the cooking utensil is further defined.
[0068] The cooking appliance also includes a housing and a cover. The inner surface of the housing encloses the cooking cavity, and the cover is placed over the housing. That is, the cover is located on the outside of the housing.
[0069] At least a portion of the flow guiding structure, the steam generator and the flow divider of the flow guiding assembly are located between the housing and the hood. That is, at least a portion of the flow guiding structure, the steam generator and the flow divider are located outside the housing, and the second outlet of the flow guiding structure is connected to the cooking cavity.
[0070] This design reduces the space occupied by the flow guide components within the cooking cavity, ensuring ample cooking space for the ingredients.
[0071] In some technical solutions, optionally, along the height direction of the cooking appliance, the second outlet is closer to the top of the cooking cavity than the bottom of the cooking cavity.
[0072] In this technical solution, the fitting structure between the second outlet and the cooking cavity is further defined.
[0073] Along the height direction of the cooking appliance, the second outlet is closer to the top of the cooking cavity than the bottom of the cooking cavity. That is, along the height direction of the cooking appliance, the distance from the second outlet to the bottom of the cooking cavity is greater than the distance from the second outlet to the top of the cooking cavity.
[0074] Steam enters the cooking chamber from the top, near the cooking cavity, through the second outlet. Due to the density difference between the high-temperature steam and the air inside the cooking chamber, the continuously introduced steam accumulates at the top of the cooking chamber, effectively expelling the air below. Because the steam does not mix with the air inside the cooking chamber, the air can be quickly expelled, rapidly reducing the oxygen content inside the cooking chamber and achieving an anaerobic steaming effect. Anaerobic steaming reduces the contact between food and oxygen, optimizing the cooking effect in terms of nutrition, taste, and safety. It helps retain nutrients, reduces oxidation loss, improves the color and taste of food, reduces the formation of harmful substances, and slows down the oxidation rate of cooking utensils, extending their lifespan and reducing the difficulty of cleaning.
[0075] In some technical solutions, optionally, when a part of the flow guiding structure is located on the periphery of the box, the box is provided with a third opening, the third opening communicating with the cooking cavity; the connecting plate of the flow guiding assembly is located on one side of the box, and the connecting plate covers the third opening, the flow guiding groove and the cover plate of the flow guiding assembly are both located inside the cooking cavity, and the second outlet faces the top of the cooking cavity.
[0076] In this technical solution, the mating structure of the flow guiding component and the housing is further defined.
[0077] When a portion of the flow guide structure is located on the periphery of the housing, the housing has a third opening that connects to the cooking cavity.
[0078] The connecting plate of the flow guide assembly is located on one side of the housing, and the connecting plate covers the third opening. That is, the connecting plate is located on the outside of the housing.
[0079] The guide channel and cover plate of the flow guiding assembly are both located inside the cooking chamber, and the second outlet faces the top of the cooking chamber, which facilitates the steam to drive downward from the top of the cooking chamber into the space inside the cooking chamber and out of the cooking chamber through the exhaust port.

[0099] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0100] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.
[0101] The following reference Figures 1 to 15 The present application describes a flow guide assembly 10 and a cooking appliance 90 according to some embodiments.
[0102] like Figure 1 As shown, a flow guiding component 10 according to some embodiments of this application includes a flow divider 100 and a flow guiding structure 400.
[0103] The distributor 100 has a first chamber 110 inside.
[0104] like Figure 2 and Figure 3 As shown, the splitter 100 is provided with a first inlet 200 and a plurality of first outlets 300.
[0105] Both the first entrance section 200 and the first exit section 300 are connected to the first chamber 110.
[0106] like Figure 14 and Figure 15 As shown, the flow guiding structure 400 has a second chamber 410 inside.
[0107] like Figure 1 As shown, the flow guiding structure 400 is provided with multiple second inlet sections 500 and second outlet sections 600.
[0108] Each first exit section 300 is connected to a second chamber 410 via a second entrance section 500.
[0109] The second outlet 600 connects to the second chamber 410.
[0110] The flow guiding component 10 provided in this application includes a flow divider 100 and a flow guiding structure 400.
[0111] The distributor 100 has a first chamber 110, a first inlet 200 and a plurality of first outlets 300, and any one of the plurality of first outlets 300 and the first inlet 200 communicates with the first chamber 110. The first inlet 200 is used to communicate with the steam generator 810 of the cooking appliance 90.
[0112] The flow guiding structure 400 has a second chamber 410, and the flow guiding structure 400 has multiple second inlets 500 and second outlets 600. Each first outlet 300 is connected to the second chamber 410 through a second inlet 500, and the second outlet 600 is connected to the second chamber 410. The second outlet 600 is used to supply steam to the cooking chamber 910 of the cooking appliance 90.
[0113] The flow guiding assembly 10 is used in a cooking appliance 90, which has a cooking cavity 910. A steam generator 810 is connected to a first inlet 200 of a distributor 100, and a second outlet 600 of the flow guiding assembly 10 is connected to the cooking cavity 910. When the cooking appliance 90 is in operation, the steam generated by the steam generator 810 flows into the cooking cavity 910 via the flow guiding assembly 10. Specifically, the steam generated by the steam generator 810 enters a first chamber 110 through the first inlet 200, then flows simultaneously through multiple first outlets 300 to multiple second inlets 500, then flows into a second chamber 410, and finally flows into the cooking cavity 910 through the second outlet 600.
[0114] It is understandable that the cross-sectional area of the first inlet 200 is smaller than that of the first chamber 110. Steam enters the first chamber 110 with a larger cross-sectional area through the first inlet 200 with a smaller cross-sectional area. The larger volume of the first chamber 110 can provide a buffer space for the steam. When the steam flows in at high speed from the first inlet 200, the expansion of the chamber volume will reduce the steam velocity and alleviate pressure fluctuations. The steam will diffuse to the surrounding low-pressure areas and flow to the multiple second inlets 500 through the multiple first outlets 300.
[0115] Understandably, steam flows into the second chamber 410 simultaneously through multiple second inlets 500, meaning the steam is diverted by the distributor 100 before entering the second chamber 410. Due to the increased volume of the second chamber 410, the steam velocity and pressure are further reduced, and finally, the steam enters the top 912 of the cooking chamber at a low speed through the second outlet 600 in a laminar flow manner. Because of the density difference between the high-temperature steam and the air inside the cooking chamber 910, the continuously introduced steam accumulates above the cooking chamber 910 under the influence of this density difference, allowing the air below to be effectively discharged from the cooking chamber 910 through the exhaust port. Because the steam does not mix with the air inside the cooking cavity 910, the air inside the cooking cavity 910 can be quickly expelled, thereby rapidly reducing the oxygen content inside the cooking cavity 910 and achieving an anaerobic steaming effect. Anaerobic steaming reduces the contact between food and oxygen, which can optimize the cooking effect of food in terms of nutrition, taste and safety. It is beneficial to retain the nutrients of food, reduce oxidation loss, improve the color and taste of food, and reduce the generation of harmful substances. At the same time, it can also reduce the oxidation rate of cooking utensils 90, which is beneficial to extend the service life of cooking utensils 90 and reduce the difficulty of cleaning cooking utensils 90.
[0116] In addition, there are multiple first outlets 300 and second inlets 500. Each first outlet 300 is connected to the second chamber 410 through a second inlet 500. In this way, steam can flow into the second chamber 410 from multiple directions and multiple positions at the same time, so that different areas in the second chamber 410 are effectively filled with steam, providing structural support for subsequent steam to enter the cooking cavity 910 through the second outlet 600 in a low-speed laminar flow manner.
[0117] Specifically, a high oxygen content within the cooking cavity 910 will severely affect cooking results and the lifespan of the cooking appliance 90. For example, components such as fats, pigments, and vitamins in food are easily oxidized, leading to discoloration and poor texture (e.g., meat becomes tough, rice becomes dry and hard). Furthermore, cooking appliances 90 made of materials such as stainless steel and cast iron will oxidize more rapidly due to prolonged exposure to high-oxygen steam, particularly resulting in rust spots or limescale buildup on the walls of the cooking cavity 910, thus affecting their lifespan and increasing the difficulty of cleaning.
[0118] Specifically, the first inlet 200 is cross-sectioned along a direction perpendicular to the first inlet 200 to the first chamber 110. In the cross-section, the area enclosed by the inner contour line of the first inlet 200 is the flow cross-sectional area of the first inlet 200.
[0119] The first chamber 110 is cross-sectionally oriented along a direction perpendicular to the first inlet 200 to the first outlet 300. In this cross-section, the area enclosed by the contour line of the first chamber 110 wall is the flow cross-sectional area of the first chamber 110.
[0120] Specifically, the second chamber 410 is cross-sectionally divided along a direction perpendicular to the second inlet 500 to the second outlet 600. In the cross-section, the area enclosed by the contour line of the cavity wall of the second chamber 410 is the flow cross-sectional area of the second chamber 410.
[0121] In some embodiments, exemplarily, such as Figure 2 and Figure 3 As shown, the first inlet 200 is located on the first side of the splitter 100.
[0122] Multiple first outlet sections 300 are located on the second side of the splitter 100.
[0123] The first side and the second side of the splitter 100 are adjacent sides of the splitter 100.
[0124] In this embodiment, the arrangement positions of the first inlet 200 and the plurality of first outlets 300 are further defined.
[0125] The first inlet 200 is located on a first side of the splitter 100, and a plurality of first outlets 300 are located on a second side of the splitter 100. That is, the first inlet 200 and the first outlets 300 are located on different sides of the splitter 100. Specifically, the first inlet 200 and the first outlets 300 are located on adjacent sides of the splitter 100.
[0126] In this way, the steam entering the first chamber 110 through the first inlet 200 will not flow directly to the multiple first outlets 300. Instead, it will be deflected upon impacting the walls of the first chamber 110 and then flow through the flow guide structure 400 via the multiple first outlets 300. It can be understood that the relatively high-velocity steam, after impacting the walls of the first chamber 110, can flow to the multiple first outlets 300 at a relatively uniform flow rate. This helps to balance the velocity and flow rate of the steam flowing to the multiple second inlets 500.
[0127] In some embodiments, exemplarily, such as Figure 2 and Figure 3 As shown, the splitter 100 includes a first end wall 120, a second end wall 130, and a circumferential wall 140.
[0128] The first entrance 200 is located on the first end wall 120.
[0129] At least a portion of the second end wall 130 is a dish-shaped wall.
[0130] The circumferential wall 140 is connected between the first end wall 120 and the second end wall 130.
[0131] The first end wall 120, the second end wall 130, and the circumferential wall 140 enclose the first chamber 110.
[0132] Multiple first exit sections 300 are located on the circumferential wall 140.
[0133] In this embodiment, the splitter 100 includes a first end wall 120, a second end wall 130, and a circumferential wall 140.
[0134] The first end wall 120 and the second end wall 130 are arranged opposite to each other and spaced apart. The circumferential wall 140 is connected between the first end wall 120 and the second end wall 130. The first end wall 120, the second end wall 130 and the circumferential wall 140 enclose the first chamber 110.
[0135] The first inlet 200 is located on the first end wall 120, and the multiple first outlets 300 are located on the circumferential wall 140, which can meet the usage requirements of the first inlet 200 and the first outlets 300 being located on adjacent sides of the splitter 100.
[0136] Specifically, the steam entering the first chamber 110 through the first inlet 200 at the first end wall 120 will flow to the second end wall 130. Since at least a portion of the second end wall 130 is a dish-shaped wall, the steam will bend and flow evenly to the multiple first outlets 300 of the circumferential wall 140 after impacting the second end wall 130. In other words, the steam will flow to the multiple first outlets 300 at a uniform flow rate after impacting the second end wall 130.
[0137] For example, at least a portion of the plurality of first outlet sections 300 are arranged at equal intervals.
[0138] For example, the circumferential wall 140 is cross-sectioned along the arrangement direction perpendicular to the first end wall 120 to the second end wall 130. In the cross-section, the shape enclosed by the outer contour of the circumferential wall 140 includes ellipse, polygon and irregular shape, wherein irregular shape refers to structure with irregular shape.
[0139] For example, the axis of the first inlet 200 is perpendicular to the axis of the first outlet 300.
[0140] In some embodiments, exemplarily, such as Figure 2 and Figure 3 As shown, the distributor 100 is also provided with a flow guide 700.
[0141] The flow guide 700 connects to the first chamber 110.
[0142] In this embodiment, the structure of the diverter 100 is further defined. The diverter 100 is also provided with a guide section 700, which is connected to the first chamber 110. The guide section 700 is used to guide the condensate accumulated in the first chamber 110 out of the diverter 100, thereby reducing the amount of condensate flowing into the guide structure 400 under the drive of steam. This provides structural support to prevent condensate from dripping into the food in the cooking cavity 910. At the same time, this structural design can also reduce the difficulty of cleaning the cooking cavity 910.
[0143] In some embodiments, for example, the first inlet 200, the first outlet 300, and the guide 700 all extend outward from the outer surface of the diverter 100.
[0144] In this embodiment, the structure of the flow guiding component 10 is further defined.
[0145] The first inlet 200, the first outlet 300, and the guide section 700 all extend outward from the outer surface of the diverter 100. That is, the first inlet 200 extends outward from the outer surface of the diverter 100, the first outlet 300 extends outward from the outer surface of the diverter 100, and the guide section 700 extends outward from the outer surface of the diverter 100. Alternatively, it can be said that the first inlet 200, the first outlet 300, and the guide section 700 all protrude from the outer surface of the diverter 100. This provides structural support for the first flexible pipe 820 connecting the first inlet 200 and the steam generator 810, and for the second flexible pipe 830 connecting the first outlet 300 and the second inlet 500, reducing the assembly difficulty of the guide assembly 10 and facilitating its disassembly and assembly.
[0146] At the same time, this arrangement is conducive to precise control of the steam flow direction. If the first inlet 200, the first outlet 300 and the guide section 700 are all located inside the distributor 100, it will result in a complex internal structure of the distributor 100, which is prone to dead zones and is not conducive to steam flow.
[0147] In some embodiments, for example, the sum of the cross-sectional areas of the plurality of second inlet portions 500 is less than the cross-sectional area of the second outlet portion 600.
[0148] In this embodiment, the mating structure of the plurality of second inlet portions 500 and the second outlet portion 600 is further defined such that the sum of the cross-sectional areas of the plurality of second inlet portions 500 is less than the cross-sectional area of the second outlet portion 600.
[0149] This increases the area of the steam guide component 10 that guides steam into the cooking cavity 910, further reducing the steam flow rate and achieving a relatively large steam output, which helps improve the uniformity of steam flowing into the cooking cavity 910 through the top 912.
[0150] In some embodiments, exemplarily, such as Figure 8 and Figure 9 As shown, at least one partition 610 is provided inside the second outlet section 600.
[0151] The inner surface of the second outlet 600 and at least one partition 610 enclose a plurality of channels 620.
[0152] Channel 620 has a first inlet end 622 and a first outlet end 624.
[0153] The first inlet end 622 connects the second chamber 410 and the first outlet end 624.
[0154] The cross-sectional area of the first inlet end 622 is smaller than the cross-sectional area of the first outlet end 624.
[0155] In this embodiment, the structure of the second outlet portion 600 is further defined such that at least one partition 610 is provided inside the second outlet portion 600. The inner surface of the second outlet portion 600 and the at least one partition 610 enclose a plurality of channels 620. That is, at least one partition 610 divides the internal space of the second outlet portion 600 into a plurality of channels 620, each channel 620 connecting to the second chamber 410.
[0156] Steam flows simultaneously through the second chamber 410 into multiple channels 620. The cross-sectional area of the first inlet end 622 is smaller than that of the first outlet end 624. The change in the cross-sectional area of the first inlet end 622 and the first outlet end 624 alters the steam velocity, thereby reducing it. Furthermore, this change in the cross-sectional area also helps to diffuse the concentrated steam flow over a wider area, such as from the center of the channel 620 outwards. This avoids dead zones, reduces localized high-speed turbulence, and allows the steam to be evenly distributed in the cooking chamber 910 at a low speed laminar flow through the second outlet 600, thus improving the cooking efficiency of the cooking appliance 90.
[0157] In addition, the combination of multiple channels 620 with varying cross-sectional areas can enhance the effect of reducing steam velocity and improving the uniform distribution of steam.
[0158] For example, the cross-sectional area of the channel 620 gradually increases along the direction from the second inlet 500 to the second outlet 600.
[0159] For example, along the direction from the second inlet 500 to the second outlet 600, the cross-sectional area of a portion of the channel 620 gradually increases.
[0160] In some embodiments, exemplarily, such as Figure 12 As shown, the second outlet section 600 has a second inlet end 630 and a second outlet end 640.
[0161] The second inlet end 630 connects to the second outlet end 640 and the second chamber 410.
[0162] The cross-sectional area of the second inlet end 630 is smaller than that of the second outlet end 640.
[0163] In this embodiment, the structure of the second outlet 600 is further defined. The second outlet 600 has a second inlet end 630 and a second outlet end 640. The second inlet end 630 communicates with the second outlet end 640 and the second chamber 410.
[0164] Steam flows through the second chamber 410 to the second inlet 630, and then into the cooking chamber 910 through the second outlet 640. The cross-sectional area of the second inlet 630 is smaller than that of the second outlet 640. This change in the cross-sectional area of the second inlet 630 and the second outlet 640 alters the steam velocity, thus reducing it. Furthermore, this change in cross-sectional area also helps to diffuse the concentrated steam flow over a wider area, such as from the center of the second outlet 600 outwards. This avoids dead zones, reduces localized high-speed turbulence, and allows the steam to be evenly distributed in the cooking chamber 910 in a low-speed laminar flow manner through the second outlet 600, thereby improving the cooking efficiency of the cooking appliance 90.
[0165] For example, the cross-sectional area of the second outlet 600 gradually increases along the direction from the second inlet 500 to the second outlet 600.
[0166] For example, along the direction from the second inlet 500 to the second outlet 600, the cross-sectional area of a portion of the second outlet 600 gradually increases.
[0167] In some embodiments, for example, a plurality of second inlets 500 are located on the first side of the flow guiding structure 400.
[0168] The second outlet 600 is located on the second side of the flow guide structure 400.
[0169] The first side and the second side of the flow guiding structure 400 are adjacent sides of the flow guiding structure 400.
[0170] In this embodiment, the arrangement positions of the plurality of second inlet portions 500 and second outlet portions 600 are further defined.
[0171] Multiple second inlet portions 500 are located on the first side of the flow guiding structure 400, and a second outlet portion 600 is located on the second side of the flow guiding structure 400. That is, the second inlet portions 500 and the second outlet portions 600 are located on different sides of the flow guiding structure 400. Specifically, the second inlet portions 500 and the second outlet portions 600 are located on adjacent sides of the flow guiding structure 400.
[0172] In this way, the steam entering the second chamber 410 through the multiple second inlets 500 will not flow directly to the second outlet 600. Instead, it will be deflected upon impacting the walls of the second chamber 410 and then flow to the cooking chamber 910 via the second outlet 600. It is understandable that the relatively high-velocity steam, after impacting the walls of the second chamber 410, can flow to the second outlet 600 at a relatively uniform flow rate. This helps to balance the velocity and flow rate of the steam entering the cooking chamber 910.
[0173] In some embodiments, exemplarily, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the flow guiding structure 400 includes a connecting plate 420, a flow guiding groove 430, and a cover plate 440.
[0174] Multiple second inlets 500 are located on the same side of the connecting plate 420.
[0175] The flow channel 430 is connected to the side of the connecting plate 420 away from the second inlet 500.
[0176] The guide channel 430 connects to the second inlet section 500.
[0177] The cover plate 440 is placed on the guide channel 430.
[0178] The second outlet section 600 is located on cover plate 440.
[0179] The connecting plate 420, the guide channel 430, and the cover plate 440 enclose the second chamber 410.
[0180] In this embodiment, the composition of the flow guiding structure 400 is further defined.
[0181] The flow guiding structure 400 includes a connecting plate 420, a flow guiding channel 430, and a cover plate 440.
[0182] Multiple second inlet portions 500 are located on the same side of the connecting plate 420, and the guide channel 430 is connected to the side of the connecting plate 420 opposite to the second inlet portions 500. That is, the second inlet portions 500 and the guide channel 430 are located on opposite sides of the connecting plate 420. The guide channel 430 communicates with the second inlet portions 500.
[0183] Furthermore, a cover plate 440 is placed over the guide channel 430, and a second outlet 600 is provided on the cover plate 440. The connecting plate 420, the guide channel 430, and the cover plate 440 enclose the second chamber 410. That is, the steam flowing into the second chamber 410 through the multiple second inlets 500 on the connecting plate 420 will flow into the guide channel 430. After impacting the wall of the guide channel 430, the steam will be deflected by the wall of the guide channel 430 and flow to the second outlet 600 of the cover plate 440.
[0184] Understandably, the steam flow rate will be further reduced after it impacts the walls of the guide channel 430.
[0185] Understandably, the cover plate 440 covers the guide channel 430, and the connecting plate 420 is located between the second inlet 500 and the guide channel 430. That is, the second inlet 500 is located on the side of the guide channel 430, and the second outlet 600 is located above the guide channel 430. This arrangement provides structural support for the downward flow of steam from the top 912 of the cooking chamber. Furthermore, because the second inlet 500 is located on the side of the guide channel 430, the space at the top of the cooking appliance 90 is relatively small, while the space on the outer side of the cooking appliance 900 is relatively large. Therefore, this arrangement ensures that the second inlet 500 does not occupy the space at the top of the cooking appliance 90, effectively utilizing the existing installation space for installation and positioning of the cooking appliance 90.
[0186] In some embodiments, exemplarily, such as Figure 4 and Figure 7 As shown, the channel wall of the guide channel 430 includes an inclined wall 432.
[0187] The inclined wall 432 is opposite to the connecting plate 420 and is arranged at intervals.
[0188] Along the direction from the guide channel 430 to the cover plate 440, the distance between the inclined wall 432 and the connecting plate 420 gradually increases.
[0189] In this embodiment, the structure of the flow channel 430 is further defined.
[0190] The channel wall of the guide channel 430 includes an inclined wall 432, which is opposite to and spaced apart from the connecting plate 420.
[0191] The inclined wall 432 extends in a specific direction, with the distance between the inclined wall 432 and the connecting plate 420 gradually increasing along the direction from the guide channel 430 to the cover plate 440. The inclined wall 432 serves to guide steam upwards along its extension direction to the cover plate 440. In other words, the inclined wall 432 guides the steam to flow orderly to the second outlet 600 of the cover plate 440, providing structural support for the steam to flow into the cooking cavity 910 through the second outlet 600.
[0192] In some embodiments, exemplarily, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the flow channel 430 has a first opening 433, a second opening 434, and a surrounding edge 435.
[0193] The rim 435 is set around the first opening 433.
[0194] The edge 435 abuts against the connecting plate 420.
[0195] The second opening 434 connects the second outlet 600 and the first opening 433.
[0196] The first opening 433 connects to each of the second entrances 500.
[0197] like Figure 8 , Figure 10 and Figure 11 As shown, the cover plate 440 is provided with a slot 442, and the side of the guide channel 430 with a second opening 434 is inserted into the slot 442.
[0198] In this embodiment, the structure of the flow channel 430 is further defined.
[0199] The guide channel 430 has a first opening 433 and a second opening 434. Each second inlet 500 is connected to the second opening 434 through the first opening 433, and the second opening 434 is connected to the second outlet 600. Specifically, steam flows into the first opening 433 through the multiple second inlets 500, and then flows into the second outlet 600 through the second opening 434.
[0200] The guide channel 430 also has a surrounding edge 435, which surrounds the first opening 433 and abuts against the connecting plate 420. This arrangement increases the contact area between the guide channel 430 and the connecting plate 420, facilitating the assembly of the connecting plate 420 and the guide channel 430. For example, the surrounding edge 435 and the connecting plate 420 are bonded together to ensure the airtightness of the connection between the connecting plate 420 and the guide channel 430, preventing steam leakage through the connection between the connecting plate 420 and the guide channel 430.
[0201] The cover plate 440 is provided with a slot 442. The side of the guide channel 430 with a second opening 434 is inserted into the slot 442. That is, the side of the guide channel 430 with the second opening 434 is inserted into the slot 442. This arrangement increases the mating area between the cover plate 440 and the guide channel 430. A part of the guide channel 430 is inserted into the slot 442. The slot 442 has the function of limiting the guide channel 430, which can ensure the relative displacement between the cover plate 440 and the guide channel 430, and is conducive to improving the stability and reliability of the guide structure 400 assembly.
[0202] In some embodiments, exemplarily, such as Figure 1 and Figure 13 As shown, the flow guiding assembly 10 also includes a steam generator 810, a first flexible tube 820, and a plurality of second flexible tubes 830.
[0203] The first flexible tube 820 connects the steam generator 810 and the first inlet 200.
[0204] Each first outlet 300 is connected to a second inlet 500 via a second flexible tube 830.
[0205] In this embodiment, the structure of the flow guiding component 10 is further defined.
[0206] The flow guiding assembly 10 also includes a steam generator 810, a first flexible tube 820, and a plurality of second flexible tubes 830.
[0207] Each first outlet 300 is connected to a second inlet 500 via a second flexible tube 830.
[0208] The first flexible tube 820 and multiple second flexible tubes 830 work together to ensure the flow path of steam.
[0209] Understandably, the steam generator 810 can generate steam when it is working. The steam flows through the first flexible pipe 820 to the distributor 100. After being split by the distributor 100, the steam flows through multiple second flexible pipes 830 to the guide structure 400.
[0210] It is understood that both the first flexible tube 820 and the second flexible tube 830 are flexible, and their shapes are variable. The shapes of the first flexible tube 820 and the second flexible tube 830 can be adaptively adjusted according to the specific positions of the distributor 100, the guide structure 400, and the housing 900 to ensure the steam flow path and meet the usage requirements of various types of cooking appliances 90.
[0211] A cooking appliance 90 according to some embodiments of this application includes: a flow guide component 10 as described in any of the above embodiments.
[0212] The cooking appliance 90 provided in this application includes the flow guiding component 10 as described in any of the above embodiments, and therefore has all the beneficial effects of the flow guiding component 10, which will not be described in detail here.
[0213] In some embodiments, exemplarily, such as Figure 13 and Figure 14 As shown, the cooking appliance 90 also includes a housing 900 and a cover 1000.
[0214] The inner surface of the housing 900 encloses the cooking cavity 910.
[0215] The second outlet section 600 connects to the cooking chamber 910.
[0216] The cover 1000 is installed on the box 900.
[0217] At least a portion of the flow guiding structure 400, the steam generator 810 of the flow guiding assembly 10, and the distributor 100 are all located between the housing 900 and the hood 1000.
[0218] In this embodiment, the structure of the cooking utensil 90 is further defined.
[0219] The cooking appliance 90 also includes a housing 900 and a cover 1000. The inner surface of the housing 900 encloses a cooking cavity 910, and the cover 1000 covers the housing 900. That is, the cover 1000 is located on the outside of the housing 900.
[0220] At least a portion of the flow guiding structure 400, the steam generator 810 of the flow guiding assembly 10, and the distributor 100 are all located between the housing 900 and the hood 1000. That is, at least a portion of the flow guiding structure 400, the steam generator 810, and the distributor 100 are all located outside the housing 900, and the second outlet 600 of the flow guiding structure 400 communicates with the cooking cavity 910.
[0221] This configuration reduces the space occupied by the flow guide component 10 in the cooking cavity 910, ensuring sufficient space for food preparation.
[0222] In some embodiments, exemplary, along the height direction of the cooking appliance 90, the second outlet 600 is closer to the top 912 of the cooking cavity than the bottom 914 of the cooking cavity.
[0223] In this embodiment, the mating structure of the second outlet 600 and the cooking cavity 910 is further defined.
[0224] Along the height direction of the cooking appliance 90, the second outlet 600 is closer to the top 912 of the cooking cavity than the bottom 914 of the cooking cavity. That is, along the height direction of the cooking appliance 90, the distance from the second outlet 600 to the bottom 914 of the cooking cavity is greater than the distance from the second outlet 600 to the top 912 of the cooking cavity.
[0225] Steam enters the cooking chamber 910 from the top 912 near the cooking chamber via the second outlet 600. Due to the density difference between the high-temperature steam and the air inside the cooking chamber 910, the continuously introduced steam accumulates above the cooking chamber 910, effectively expelling the air below. Because the steam does not mix with the air inside the cooking chamber 910, the air inside the cooking chamber 910 can be quickly expelled, thereby rapidly reducing the oxygen content inside the cooking chamber 910 and achieving an anaerobic steaming effect. Anaerobic steaming reduces the contact between food and oxygen, optimizing the cooking effect in terms of nutrition, taste, and safety. It helps retain nutrients, reduces oxidation loss, improves the color and taste of food, reduces the formation of harmful substances, and slows down the oxidation rate of the cooking utensils 90, thus extending their service life and reducing the difficulty of cleaning.
[0226] In some embodiments, exemplarily, such as Figure 14 and Figure 15 As shown, when a portion of the flow guiding structure 400 is located on the periphery of the housing 900, the housing 900 is provided with a third opening 920.
[0227] The third opening 920 connects to the cooking cavity 910.
[0228] The connecting plate 420 of the flow guide assembly 10 is located on one side of the housing 900, and the connecting plate 420 covers the third opening 920.
[0229] The flow channel 430 and the cover plate 440 of the flow guide assembly 10 are both located inside the cooking cavity 910.
[0230] The second outlet 600 faces the top 912 of the cooking cavity.
[0231] In this embodiment, the mating structure of the flow guiding component 10 and the housing 900 is further defined.
[0232] When a portion of the flow guiding structure 400 is located on the periphery of the housing 900, the housing 900 is provided with a third opening 920, which connects to the cooking cavity 910.
[0233] The connecting plate 420 of the flow guiding assembly 10 is located on one side of the housing 900, and the connecting plate 420 covers the third opening 920. That is, the connecting plate 420 is located on the outside of the housing 900.
[0234] The guide channel 430 and cover plate 440 of the guide assembly 10 are both located inside the cooking chamber 910, and the second outlet 600 faces the top 912 of the cooking chamber, which facilitates the steam to be driven downward from the top 912 of the cooking chamber into the space inside the cooking chamber 910 and discharged from the cooking chamber 910 through the exhaust port.
[0235] For example, cooking appliances 90 include steam ovens, microwave steam ovens, etc., which will not be listed here.
[0236] Exemplarily, the flow guiding component 10 of this application is a steam deceleration and diffusion structure. This application can decelerate the high-speed steam entering the cooking chamber 910 and diffuse it into the cooking chamber 910 in a laminar flow manner. By introducing uniform, low-speed steam into the cooking chamber 910, the steam is distributed in layers with the existing air within the cooking chamber 910 due to the influence of density differences. As steam is continuously introduced into the cooking chamber 910, the air inside the cooking chamber 910 is rapidly expelled, thereby quickly reducing the oxygen content.
[0237] For example, the flow guiding assembly 10 includes a flow divider 100 for uniform flow distribution and a flow guiding structure 400 for diffusion and flow guidance. This causes the steam to gradually slow down after entering the flow guiding assembly 10 and enter the cavity in a low-speed laminar flow state. After entering the cooking cavity 910, the low-speed, uniform steam is suspended in the upper part of the cooking cavity 910 due to the density difference. As steam continues to enter, it can quickly expel the air inside the cooking cavity 910, thereby rapidly increasing the internal temperature of the cooking cavity 910 and achieving anaerobic steaming.
[0238] For example, the flow guiding assembly 10 is mainly arranged outside the housing 900. The components of the flow guiding assembly 10 are connected by a hose assembly. The flow guiding assembly 10 is small in size and flexible in arrangement. The hose assembly includes a first flexible tube 820 and a plurality of second flexible tubes 830.
[0239] For example, the diverter 100 is provided with a guide section 700 for discharging condensate. The condensate can be directly discharged into the wastewater box and will not affect the food.
[0240] For example, such as Figure 13 As shown, in order to ensure that the steam is evenly diffused in the top 912 of the cooking chamber, a part of the flow guide assembly 10 is installed on the side of the housing 900, and the second outlet 600 of the flow guide assembly 10 is located on the top side of the cooking chamber 910.
[0241] For example, such as Figure 1 As shown, the flow guiding assembly 10 includes a flow divider 100 and a flow guiding structure 400. The flow guiding structure 400 includes a connecting plate 420, a flow guiding channel 430, and a cover plate 440. The flow divider 100 is connected to the steam generator 810 via a first flexible pipe 820, and the flow divider 100 is also connected to the connecting plate 420 of the flow guiding structure 400 via multiple second flexible pipes 830. The connecting plate 420 and the flow guiding channel 430 are respectively fixed to the outer wall surface and the inner wall surface of the housing 900 by welding.
[0242] For example, the diverter 100 is provided with a first inlet 200, a plurality of first outlets 300 and a guide 700, wherein the axis of the first inlet 200 is perpendicular to the axis of the first outlets 300. The number of first outlets 300 may be 2, 3, 4 or 5, etc., and will not be listed here.
[0243] For example, the guide channel 430 is a channel structure made of the same material as the cooking cavity 910. The second opening 434 of the guide channel 430 faces the top 912 of the cooking cavity. The guide channel 430 is used to deflect the steam so that the steam flows towards the top 912 of the cooking cavity.
[0244] For example, such as Figure 5As shown, the cover plate 440 is provided with a slot and a second outlet 600. The slot has the same shape as the guide channel 430 and is used for assembly with the guide channel 430. The second outlet 600 adopts a gradually expanding structure to slow down the steam and make the steam diffuse evenly. A cross-section of the second outlet 600 is taken along the length direction perpendicular to the second outlet 600. In the cross-section, the inner contour of the second outlet 600 includes a circular or rectangular shape.
[0245] For example, steam generated by steam generator 810 enters distributor 100 through first flexible tube 820. Since the axis of the first inlet 200 of distributor 100 is perpendicular to the axis of the first outlet 300, the steam will flow to multiple first outlets 300 at a uniform flow rate after impacting the inner wall of distributor 100. After being split by distributor 100, the steam velocity and pressure decrease due to the increased flow cross-section. It then enters the second chamber 410 enclosed by connecting plate 420, guide channel 430, and cover plate 440 through multiple second flexible tubes 830. Due to the increased volume of the second chamber 410, the steam velocity and pressure are further reduced. Finally, the steam is further decelerated by the gradually expanding second outlet 600 on cover plate 440 and enters cooking chamber 910 in a low-speed laminar flow manner. Due to the density difference between the high-temperature steam and the air inside the cooking cavity 910, the continuously introduced steam accumulates above the cooking cavity 910 under the influence of this density difference, causing the air below to be expelled from the cooking cavity 910. Since the steam does not mix with the air, the air inside the cooking cavity 910 is rapidly expelled, thereby quickly reducing the oxygen content inside the cooking cavity 910 and achieving an anaerobic steaming effect.
