Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a cooking appliance. BACKGROUND

[0002] In the related scheme, the steamer heats the food material through water vapor. When the high-temperature steam enters the cooking cavity, it condenses and releases heat, which produces condensed water in the cooking cavity. On the one hand, during the steaming process, part of the condensed water droplets fall onto the food material or into the food material container, affecting the taste of the food material. On the other hand, after the steaming is completed, when the user uncovers the pot cover, the condensed water will flow onto the table or the ground, and if it contacts a person, it will cause a burn, affecting the user experience.

[0003] Therefore, how to design a cooking appliance that can reduce condensed water has become a problem to be solved at present. UTILITY MODEL CONTENT

[0004] The present application aims to at least solve the technical problem that the existing technology or related technology has a cooking appliance that produces condensed water in the cooking cavity when heating the food material through water vapor, resulting in poor taste of the food material, and after the steaming is completed, when the user uncovers the pot cover, the condensed water will flow onto the table or the ground, and if it contacts a person, it will cause a burn, affecting the user experience.

[0005] To this end, the first aspect of the present application is to provide a cooking appliance.

[0006] According to the cooking appliance provided by the present application, the cooking appliance comprises a pot body comprising a cooking cavity, a pot cover for covering the pot body, the pot cover being provided with a steam inlet, a steam generating device connected with the steam inlet to deliver steam to the cooking cavity, a baffle located on the inner side of the pot cover and surrounding the pot cover to form a steam buffer cavity, the steam buffer cavity being in communication with the steam inlet, and a first communication channel for communicating the steam buffer cavity and the cooking cavity.

[0007] According to the cooking utensil provided in the present application, the cooking utensil comprises a pot body, a pot cover, a steam generating device and a baffle. The steam generating device is used to generate steam and pass the steam into the space between the pot cover and the pot body from the steam inlet of the pot cover. The baffle is arranged on the inner side of the pot cover and can be arranged on the pot cover or the pot body. A steam buffer cavity is formed between the baffle and the pot cover. The steam entering the inner side of the pot cover from the steam inlet is first gathered in the steam buffer cavity and then enters the cooking cavity through the first communication channel. In this structure, during the working process of the cooking utensil, the steam generated from the top of the pot cover enters the steam buffer cavity. At the current temperature and pressure, the density of water vapor is smaller than that of air, and the water vapor is blocked by the baffle. Therefore, the water vapor gradually fills the steam buffer cavity and then enters the cooking cavity through the first communication channel. In this process, the water vapor first contacts the baffle, condenses on the upper surface of the baffle (i.e., the surface of the baffle close to the inner surface of the pot cover) and releases heat, so that the temperature of the baffle is increased. When the steam enters the cooking cavity from the first communication channel, the steam is difficult to condense on the lower surface of the baffle (i.e., the surface of the baffle away from the inner surface of the pot cover) because the baffle has a high temperature. Therefore, the problem of condensate water gathering and dropping on the food or the container from the top of the pot cover can be avoided.

[0008] Optionally, the baffle is arranged on the inner side of the pot cover or the baffle is arranged in the pot body.

[0009] In this technical solution, the baffle can be arranged on the pot cover or the pot body according to actual needs. The specific installation position of the baffle is not limited as long as the baffle is arranged on the inner side of the pot cover and can form the steam buffer cavity with the pot cover.

[0010] Optionally, the inlet of the first communication channel and the steam inlet are arranged in a staggered manner along the height direction of the pot body.

[0011] In this technical solution, the inlet of the first communication channel and the steam inlet are not arranged on a straight line along the height direction of the pot body, i.e., the inlet and the steam inlet are staggered in the height direction. In this way, the steam entering from the steam inlet can be prevented from directly entering the first communication channel without being buffered in the steam buffer cavity.

[0012] Optionally, a first gap is formed between the edge of the baffle and the pot cover, and the first gap constitutes the first communication channel.

[0013] In the technical solution, the steam buffer cavity and the cooking cavity are communicated through the gap between the edge of the baffle and the lid, so that a channel is not additionally arranged on the baffle, and the structure of the baffle is simplified. On the other hand, the distance between the inlet of the first communication channel and the steam inlet is far, so that the steam entering from the steam inlet can be prevented from directly entering the first communication channel, the residence time of the steam in the steam buffer cavity is prolonged, and the buffering effect of the steam buffer cavity on the steam is improved. At the same time, the baffle is not punched, and the condensed water on the upper surface of the baffle is prevented from dripping from the hole of the baffle.

[0014] Optionally, the surface of the baffle close to the lid is an arc surface protruding towards the lid. At this time, a first distance is arranged between the baffle and the inner bottom wall of the lid along the axial direction of the lid, and the first distance increases from inside to outside along the radial direction of the lid.

[0015] In the technical solution, the baffle is an arc structure protruding towards the lid, so that the condensed water formed on the upper surface of the baffle can fall along the baffle under the action of gravity, and the condensed water on the upper surface of the baffle can also be naturally drained away. In addition, the arc-shaped baffle is beneficial to the flow of steam in the steam buffer cavity, so that the efficiency of steam flowing out of the steam buffer cavity can be improved, and the efficiency of steam filling the cooking cavity can be improved.

[0016] Further, the size of the gap between the baffle and the side wall of the lid can be adjusted to make the condensed water on the baffle flow down along the side wall of the lid, so that part of the condensed water on the side wall of the lid can also be taken away in the process of dripping, so that the problem of residual condensed water in the lid after work can be further improved.

[0017] Optionally, the arc surface extends from the middle of the baffle to the periphery of the baffle in a direction away from the lid, that is, the surface of the baffle close to the lid is an arc surface with a high middle and a gradually downward extending periphery.

[0019] Optionally, a flow guide part is arranged on the edge of the baffle and extends to the inner side of the baffle in a direction away from the lid.

[0020] In the technical solution, the flow guide part is arranged at the position of the peripheral edge of the baffle, and the flow guide part faces the center of the cooking cavity, that is, the food placement position. When the steam is discharged from the first communication channel, the flow guide part can guide the top steam to move towards the food by using the Coanda effect, so that the steam can contact the food more quickly, and the cooking efficiency can be improved.

[0021] Optionally, the guide portion is annularly arranged along the edge of the baffle, and the guide portion extends obliquely away from the pot cover from the periphery of the baffle to the center of the baffle. In this technical solution, a circular arc transition can be arranged at the periphery of the baffle to form the guide portion. The guide portion is obliquely arranged downward from the outside to the inside, so that the steam can be guided to flow gradually inward and downward, and the steam can be brought into contact with the food material more quickly, thereby improving the cooking efficiency.

[0022] Optionally, the guide portion is annularly arranged along the edge of the baffle, and the guide portion extends obliquely away from the pot cover from the periphery of the baffle to the center of the baffle. In this technical solution, a circular arc transition can be arranged at the periphery of the baffle to form the guide portion. The guide portion is obliquely arranged downward from the outside to the inside, so that the steam can be guided to flow gradually inward and downward, and the steam can be brought into contact with the food material more quickly, thereby improving the cooking efficiency.

[0023] Optionally, the baffle is detachably connected with the pot cover. During use, the baffle can be detached according to actual needs, so as to facilitate cleaning of the baffle.

[0024] Optionally, the steam inlet is arranged on the top wall of the pot cover, a surrounding rib is arranged on the inner top wall of the pot cover and surrounds the steam inlet in the circumferential direction, and steam outlet holes are arranged on the surrounding rib. The baffle is detachably connected with the surrounding rib.

[0025] In this technical solution, the baffle is detachably mounted on the top wall of the pot cover, so that the gap between the baffle and the pot cover is moderate, and the distance between the baffle and the pot cover is not too large to cause waste of space.

[0026] Optionally, at least two first buckles are arranged on the pot cover and are symmetrically arranged along a first direction; at least two second buckles are arranged on the baffle and are symmetrically arranged along the first direction; and at least one of the second buckles and the first buckles can move along the first direction to enable the first buckles and the second buckles to cooperate or disengage.

[0027] In this technical solution, the pot cover and the baffle are detachably connected through buckles. When the baffle is detached or mounted, the second buckles or the first buckles are slid to enable the first buckles and the second buckles to cooperate or disengage, so that the baffle can be detached or mounted on the pot cover.

[0028] Exemplarily, the first buckles are arranged on the surrounding rib, so that the baffle and the surrounding rib are detachably connected through the buckles, thereby realizing detachable connection between the baffle and the pot cover.

[0029] Further, the baffle and the pot cover are detachably connected through a connecting assembly. The connecting assembly comprises first and second connecting members that are buckled to each other. The first connecting member is mounted on the surrounding rib and is provided with the first buckles, the second connecting member is mounted on the baffle, and the first connecting member is provided with the second buckles that can move. When the baffle is detached or mounted, the second buckles are slid to enable the first buckles and the second buckles to cooperate or disengage, so that the baffle can be detached or mounted on the pot cover.

[0030] Optionally, the cooking appliance also includes a spring disposed between at least two second latches arranged symmetrically along the first direction.

[0031] The spring design allows the second latch to automatically reset after movement, eliminating the need for manual reset and simplifying operation. Furthermore, the spring pre-tightens the second latch, preventing it from wobbling and potentially disengaging from the first latch.

[0032] Optionally, the pot body includes: a base on which a steam generator is mounted; a steamer on the pot body, with a pot lid for covering the steamer; and a drip tray between the base and the steamer, the drip tray and the steamer forming a cooking cavity.

[0033] The cooking appliance is an electric steamer. Therefore, the pot body specifically includes a base. The base is used to support and install components such as the steamer basket, and to house the steam generator. The steamer basket, together with the drip tray, forms a cooking cavity to hold the food. By placing the steam generator on the base, the components can be installed more compactly, avoiding the need for multiple components to be scattered.

[0034] The number of steamers can be one or more, and each steamer can be equipped with a corresponding steaming plate.

[0035] Optionally, the cooking appliance further includes: a first gas guiding assembly, including a first gas guiding pipe and a mounting shell, the mounting shell being installed on the outside of the pot lid, the first gas guiding pipe being installed inside the mounting shell, and one end of the first gas guiding pipe being connected to the steam inlet; and a second gas guiding assembly, including a column and a second gas guiding pipe, the column being installed on one side of the base and extending toward the direction of the steamer, the second gas guiding pipe being installed inside the column, one end of the second gas guiding pipe being connected to the steam generating device, and the other end of the second gas guiding pipe being detachably connected to the other end of the first gas guiding pipe.

[0036] In this technical solution, when the steam generator is installed on the base, steam can be introduced to the top of the pot lid through the first and second air guiding components. The first and second air guiding components are detachably connected via a plug-in connection, allowing for easy connection or separation between the components during the opening and closing of the pot lid, thus simplifying the user's operation.

[0037] Optionally, the first gas guide assembly can be detachably mounted on the pot lid. When not in use, the first gas guide assembly can be removed for cleaning.

[0038] Optionally, the mounting housing includes an upper support and a lower support that are interconnected. A first air guide tube is disposed between the upper support and the lower support.

[0039] Optionally, the cooking utensil further comprises a second heating device installed in the stand column for heating the second air duct.

[0040] By arranging the second heating device, the steam generated by the steam generating device can be heated again by the second heating device, so that high-temperature steam with a temperature higher than 100℃ is generated, and the cooking speed is improved.

[0041] Optionally, the steam generating device comprises a heating disc installed between the base and the water receiving disc, a cover located between the heating disc and the water receiving disc and detachably installed on the heating disc to form a steam generating cavity together with the heating disc, the cover being provided with a steam outlet communicating with the steam inlet, and a water tank located between the base and the water receiving disc and arranged around the cover, and a second communication channel for communicating the water tank and the steam generating cavity.

[0042] In this technical solution, the core components of the steam generating device are the heating disc, the cover and the water tank. The heating disc and the cover form a closed steam generating cavity, and the water in the steam generating cavity can be heated into steam by the heating disc. The water tank is used to supply water to the steam generating cavity. The second communication channel is arranged between the water tank and the steam generating cavity, and the water supply can be realized through the second communication channel.

[0043] Optionally, the cooking utensil further comprises a first sealing ring sleeved on the side wall of the heating disc and located at the connection between the heating disc and the cover to seal the gap between the heating disc and the cover, and the water tank is provided with a relief hole, the heating disc is located at the relief hole, and the first sealing ring is further located between the water tank and the heating disc to seal the gap between the water tank and the heating disc.

[0044] In this technical solution, the water tank is not a completely closed structure, and the water storage space of the water tank is formed by the side wall of the water tank and the cover and the heating disc. The first sealing ring is used to ensure the gap between the water tank and the heating disc, so as to avoid water leakage in the water tank. The first sealing ring can also seal the gap between the heating disc and the cover, so that the heating disc and the cover form a sealed space that can generate steam.

[0045] In addition, the water tank can also be a double-layer structure, and in this case, the first sealing ring does not seal the gap between the heating disc and the water tank, but only seals the gap between the heating disc and the cover.

[0046] Optionally, the cover comprises a cylinder body, the cylinder body is provided with a partition plate, the partition plate is provided with at least one through hole, the cylinder body, the partition plate and the heating disc form the steam generating cavity, and a cylinder cover is detachably installed on the cylinder body, the cylinder body, the partition plate and the cylinder cover form a steam discharging cavity, the steam discharging cavity communicates with the steam generating cavity through the through hole, the steam outlet is arranged on the cylinder cover or formed by the cylinder cover and the cylinder body, and the steam outlet communicates with the steam discharging cavity.

[0047] In the technical scheme, the cover body comprises a barrel and a barrel cover which are connected in a sealed manner by a second sealing ring, and the barrel has an open structure at both upper and lower ends. Meanwhile, a partition plate is arranged in the barrel to divide the barrel into upper and lower space. The upper part of the barrel is used to form a steam discharge chamber together with the barrel cover, and the lower part of the barrel is used to form a steam generation chamber together with the heating disc. Steam generated can enter the steam discharge chamber through the through hole on the partition plate, and then be delivered to the steam inlet through the steam discharge chamber, and then enter the cooking chamber.

[0048] Optionally, the cover body further comprises a second sealing ring arranged between the barrel and the barrel cover to seal the gap between the barrel and the barrel cover. The second sealing ring can ensure the sealing between the barrel and the barrel cover, and avoid steam leakage from the connection between the barrel and the barrel cover.

[0049] Optionally, the partition plate comprises a protruding part protruding towards the heating disc. By arranging the protruding part, the area of the steam generation chamber can be increased, and the volume of the steam generation chamber can be reduced, so as to accelerate the evaporation speed of water, thereby improving the steam generation rate.

[0050] Optionally, along the flow direction of the steam, the steam discharge chamber comprises a first channel communicated with the through hole and a second channel communicated with the steam outlet, the second channel is communicated with the first channel, and the cross-sectional area of the second channel is smaller than that of the first channel.

[0051] In the technical scheme, the steam discharge chamber comprises two parts, i.e. the part formed by the first channel and the part formed by the second channel. The first channel is communicated with the through hole and used to collect steam transmitted from the through hole. The second channel is mainly used for steam discharge and is communicated with the steam outlet. The cross-sectional area of the second channel is relatively small, i.e. the second channel is relatively narrow compared with the first channel, that is, the part of the steam discharge chamber is closed to form the second channel. By arranging the relatively large first channel, the volume of the steam discharge chamber can be increased to ensure that more steam can quickly enter the steam discharge chamber, and the steam can be discharged in time. By arranging the relatively narrow second channel to discharge the steam, the steam discharge speed can be improved, so that the steam can enter the cooking chamber more quickly, thereby improving the heating efficiency of the steam.

DETAILED DESCRIPTION

[0065] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0066] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced in other ways different from those described herein, and therefore the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0067] The cooking utensil according to some embodiments of the present application will be described below with reference to the accompanying drawings. Figures 1 to 9

[0068] As shown in the drawings, the cooking utensil according to the present application comprises a pot body 1, a pot cover 2, a steam generating device 3 and a baffle 4. Figures 1 to 9 The pot body 1 comprises a cooking cavity 10. The pot cover 2 is used to cover the pot body 1, and the pot cover 2 is provided with a steam inlet 22. The steam generating device 3 is connected with the steam inlet 22 to deliver steam to the cooking cavity 10. The baffle 4 is located on the inner side of the pot cover 2 and surrounds the pot cover 2 to form a steam buffer cavity 11, which is in communication with the steam inlet 22. A first communication channel 5 is used to communicate the steam buffer cavity 11 and the cooking cavity 10.

[0069] The cooking utensil according to the present application comprises a pot body 1, a pot cover 2, a steam generating device 3 and a baffle 4. The steam generating device 3 is used to generate steam and deliver the steam from the steam inlet 22 of the pot cover 2 to the space between the pot cover 2 and the pot body 1. The baffle 4 is arranged on the inner side of the pot cover 2 and can be specifically mounted on the pot cover 2 or the pot body 1. A steam buffer cavity 11 is formed between the baffle 4 and the pot cover 2. The steam entering the inner side of the pot cover 2 through the steam inlet 22 is first gathered in the steam buffer cavity 11 and then enters the cooking cavity 10 through the first communication channel 5. In this structure, during the working process of the cooking utensil, the steam generated is first introduced into the steam buffer cavity 11 from the top of the pot cover 2. Under the current temperature and pressure, the density of water vapor is smaller than that of air, and the water vapor is blocked by the baffle 4. Therefore, the water vapor gradually fills the steam buffer cavity 11, and then enters the cooking cavity 10 through the first communication channel 5. In this process, the water vapor first contacts the baffle 4, condenses and releases heat on the upper surface of the baffle 4 (i.e. the surface of the baffle 4 close to the inner surface of the pot cover 2), and the temperature of the baffle 4 rises. When the steam enters the cooking cavity 10 from the first communication channel 5, the steam is difficult to condense on the lower surface of the baffle 4 (i.e. the surface of the baffle 4 away from the inner surface of the pot cover 2) because the baffle 4 already has a high temperature. Therefore, the problem of condensate water gathering and dripping from the top of the pot cover 2 to the food or container can be avoided.

[0070] ​​

[0071] wherein, Figure 1 the arrow in the figure indicates the flow direction of the steam.

[0072] Optionally, the baffle 4 is installed on the inner side of the pot cover 2, or the baffle 4 is installed in the pot body 1.

[0074] Optionally, the inlet of the first communication channel 5 is arranged in a staggered manner with the steam inlet 22 along the height direction of the pot body 1.

[0075] In this embodiment, the inlet of the first communication channel 5 and the steam inlet 22 are not arranged on a straight line along the height direction of the pot body 1, that is, they are staggered in the height direction, so that the steam entering from the steam inlet 22 can be prevented from directly entering the first communication channel 5 without buffering in the steam buffer cavity 11.

[0076] Optionally, as shown in Figure 1 , a first gap is formed between the edge of the baffle 4 and the pot cover 2, and the first gap constitutes the first communication channel 5.

[0077] In this embodiment, the steam buffer cavity 11 and the cooking cavity 10 are communicated through the gap between the edge of the baffle 4 and the pot cover 2, so that a channel does not need to be additionally arranged on the baffle 4, thereby simplifying the structure of the baffle 4. On the other hand, this arrangement can also make the distance between the inlet of the first communication channel 5 and the steam inlet 22 farther, so that the steam entering from the steam inlet 22 can be prevented from directly entering the first communication channel 5, prolonging the residence time of the steam in the steam buffer cavity 11 and improving the buffering effect of the steam buffer cavity 11 on the steam. At the same time, this arrangement can also avoid the condensate on the upper surface of the baffle 4 from dripping from the holes on the baffle 4.

[0078] Optionally, as shown in Figure 1 , Figure 6 and Figure 7 , the surface of the baffle 4 close to the pot cover 2 is an arc surface protruding towards the pot cover 2. At this time, a first distance is provided between the baffle 4 and the inner bottom wall of the pot cover 2 along the axial direction of the pot cover 2, and the first distance increases from inside to outside along the radial direction of the pot cover 2.

[0079] In this embodiment, the baffle 4 is an arc-shaped structure protruding towards the lid 2, so that the condensed water formed on the upper surface of the baffle 4 can fall along the baffle 4 under the action of gravity, and the condensed water on the upper surface of the baffle 4 can also be naturally drained away. In addition, the arc-shaped baffle 4 is also conducive to the flow of steam in the steam buffer cavity 11, so as to improve the efficiency of the steam flowing out of the steam buffer cavity 11, and further improve the efficiency of the steam filling the cooking cavity 10.

[0080] Further, the size of the gap between the baffle 4 and the side wall of the lid 2 can be adjusted to make the condensed water on the baffle 4 flow down along the side wall of the lid 2, so that a part of the condensed water on the side wall of the lid 2 can also be taken away in the process of dropping, so as to further improve the problem of residual condensed water in the lid 2 after work.

[0081] Optionally, the arc surface extends from the middle of the baffle 4 to the periphery of the baffle 4 away from the lid 2, that is, the surface of the baffle 4 close to the lid 2 is an arc surface with high middle and low periphery.

[0083] Optionally, as shown in Figure 6 and Figure 7 , a guide portion 44 is arranged on the edge of the baffle 4, which is bent away from the lid 2 and extends to the inner side of the baffle 4.

[0084] In this embodiment, the guide portion 44 can be arranged at the position of the peripheral edge of the baffle 4, and the guide portion 44 faces the center of the cooking cavity 10, that is, the food placement position. When the steam is discharged from the first communication passage 5, the guide portion 44 can guide the top steam to move towards the food by using the Coanda effect, so as to make the steam contact the food more quickly, thereby improving the cooking efficiency.

[0085] Optionally, the guide portion 44 is arranged in a ring shape along the edge of the baffle 4, and the guide portion 44 extends away from the lid 2 from the periphery of the baffle 4 to the center of the baffle 4.

[0086] In this embodiment, a circle of arc transitions can be arranged at the position of the peripheral edge of the baffle 4 to form the guide portion 44. And the guide portion 44 is arranged to be downwardly inclined from the outside to the inside, so as to guide the steam to flow gradually inward and downward, so that the steam can contact the food more quickly, thereby improving the cooking efficiency.

[0087] Optionally, the guide portion 44 is arranged in an arc shape, that is, the guide portion 44 is an arc-shaped structure. Of course, the guide portion 44 can also be arranged in a straight line.

[0088] Optionally, the baffle 4 is detachably connected with the pot cover 2. During use, the baffle 4 can be detached according to actual needs, so as to facilitate cleaning of the baffle 4.

[0107] In this embodiment, the core components of the steam generating device 3 are the heating disc 32, the cover 34 and the water tank 36. The heating disc 32 and the cover 34 form a closed steam generating cavity, and the water in the steam generating cavity can be heated into steam by the heating of the heating disc 32. The water tank 36 is used to supply water to the steam generating cavity. The second communication passage 38 is provided between the water tank 36 and the steam generating cavity, and the water can be supplied through the second communication passage 38 when the water is supplied.

[0108] Optionally, as shown in Figure 1 and Figure 2As shown, the cooking utensil further comprises a first sealing ring 39, which is sleeved on the sidewall of the heating disc 32 and located at the joint of the heating disc 32 and the cover 34 to seal the gap between the heating disc 32 and the cover 34.

The first sealing ring 39 is further located between the water tank 36 and the heating disc 32 and seals the gap between the water tank 36 and the heating disc 32.

[0109] In this embodiment, the water tank 36 is not a completely closed structure, and the water storage space of the water tank 36 is surrounded by the sidewall of the water tank 36 and the cover 34 and the heating disc 32. The first sealing ring 39 is used to ensure the gap between the water tank 36 and the heating disc 32, so as to avoid water leakage in the water tank 36. The first sealing ring 39 can also seal the gap between the heating disc 32 and the cover 34, so that the heating disc 32 and the cover 34 surround a sealed space that can generate steam.

[0110] In addition, the water tank 36 can also be a double-layer structure, and in this case, the first sealing ring 39 does not seal the gap between the heating disc 32 and the water tank 36, but only seals the gap between the heating disc 32 and the cover 34.

[0111] Optionally, as shown in Figure 1 , Figure 2 and Figure 9 , the cover 34 comprises a barrel 342, the barrel 342 is provided with a partition plate 3422 inside, the partition plate 3422 is provided with at least one through hole, and the barrel 342, the partition plate 3422 and the heating disc 32 surround a steam generating cavity. A barrel cover 344 is detachably mounted on the barrel 342, and the barrel 342, the partition plate 3422 and the barrel cover 344 surround a steam discharge cavity 348. The steam discharge cavity 348 is communicated with the steam generating cavity through the through hole, and the steam discharge port is provided on the barrel cover 344 or surrounded by the barrel cover 344 and the barrel 342, and the steam discharge port is communicated with the steam discharge cavity 348.

[0112] In this embodiment, the cover 34 comprises a barrel 342 and a barrel cover 344, and both upper and lower ends of the barrel 342 are open structures. At the same time, the barrel 342 is provided with a partition plate 3422 inside to divide the barrel 342 into upper and lower space. The upper part of the barrel 342 is used to form a steam discharge cavity 348 with the barrel cover 344, and the lower part of the barrel 342 is used to form a steam generating cavity with the heating disc 32. After the steam is generated, it can enter the steam discharge cavity 348 through the through hole on the partition plate 3422, and then be transported to the steam inlet 22 through the steam discharge cavity 348, so as to enter the cooking cavity 10.

[0113] Optionally, as shown in Figure 1As shown, the partition 3422 comprises a protruding portion protruding towards the heat disc 32. By arranging the protruding portion, the area of the steam generating cavity can be increased, and the overall volume of the steam generating cavity can be reduced, so as to accelerate the evaporation speed of the water, thereby improving the steam generation rate.

[0114] Optionally, the cover body further comprises a second sealing ring 346 arranged between the barrel 342 and the barrel cover 344 to seal the gap between the barrel 342 and the barrel cover 344. In this way, the sealing between the barrel 342 and the barrel cover 344 can be ensured, and steam leakage can be avoided.

[0116] In this embodiment, the steam discharging cavity 348 comprises two parts, i.e. the part formed by the first passage 3482 and the part formed by the second passage 3484. The first passage 3482 is in communication with the through hole and is used to collect the steam transmitted from the through hole. The second passage 3484 is mainly used for steam discharging and is in communication with the steam outlet. The cross-sectional area of the second passage 3484 is relatively small, i.e. the second passage 3484 is relatively narrow compared with the first passage 3482, that is, the partial area of the steam discharging cavity 348 is treated by necking, thereby forming the second passage 3484. Through the larger first passage 3482, the volume of the steam discharging cavity 348 can be increased, and more steam can be quickly introduced into the steam discharging cavity 348, so as to avoid the steam discharging not in time. By arranging the relatively narrow second passage 3484 to discharge the steam, the steam discharging speed can be improved, so that the steam can enter the cooking cavity 10 more quickly, thereby improving the heating efficiency of the steam.

[0117] In the following, a specific embodiment provided by the present application will be described in detail by taking a steamer as an example. Figures 1 to 8

[0118] As shown, Figures 1 to 8 ​As shown, the steamer structure mainly includes an air guide valve upper support 722, an air guide pipe, an air guide valve lower support 724, a pot cover 2, a steam baffle assembly, a steaming plate, a steaming rack, a water receiving tray 16, a converging ring upper cover, a sealing ring, a converging ring, a water tank 36, a heating disc 32, a heating disc sealing ring, a heating disc support, a base, a heating body assembly, and a steam guide pipe. The heating disc 32, the heating disc sealing ring, and the heating disc support are all fixed at the bottom of the water tank 36 and are used to heat the water in the water tank 36 to generate steam. The converging ring, the sealing ring, and the converging ring upper cover are assembled into a converging ring assembly, wherein the bottom of the converging ring is provided with a small hole, and during the working process, as the water in the heating disc 32 position continuously evaporates, the water in the water tank 36 can be supplemented into the heating cavity through the hole. One end of the steam guide pipe is assembled on the side wall of the water tank 36, and the other end is connected to the heating body assembly. The air guide valve upper support 722, the air guide valve lower support 724, and the air guide pipe constitute an air guide valve assembly, which is used to guide the high-temperature steam after secondary heating to the cooking cavity.

[0119] As shown, Figure 3 The steam inlet of the pot cover 2 is located at the top thereof. A surrounding rib 24 (as shown in Figure 8 ) is arranged around the inlet, and the surrounding rib 24 is provided with a plurality of holes facing different directions for passing steam. Symmetrical slots are arranged on the side wall for assembling and fixing the steam baffle assembly, and a gap exists between the steam baffle assembly and the side wall of the pot cover 2 for passing steam. The exhaust hole of the pot cover 2 is arranged on the side wall of the steaming rack. The steamer can be divided into an upper cavity and a lower cavity, the pot cover 2 and the steaming plate constitute the upper cavity, and the steaming rack and the water receiving tray 16 constitute the lower cavity. Meanwhile, the steam baffle assembly divides the upper cavity into two cavities, i.e., a first cavity above the baffle assembly and a second cavity below the baffle assembly. During the working process, after the steam is generated, it enters the first cavity from the top of the pot cover 2 through the air guide valve assembly. Since the water vapor density is smaller than that of air at the current temperature and pressure, and is blocked by the baffle assembly, the water vapor will gradually fill the first cavity, and then enter the second cavity through the gap around the steam baffle 4. After filling the upper cavity, it enters the lower cavity, and finally fills the entire cooking cavity of the steamer. In this process, the water vapor first contacts the steam baffle assembly, condenses and releases heat on the outside of the baffle 4, causing the temperature of the baffle 4 to rise. When the steam enters the second cavity through the gap around the baffle 4, the baffle 4 has a high temperature, and it is difficult for the steam to condense on the inside of the baffle 4, so the problem of condensate water gathering and dropping onto the food or container at the top of the pot cover 2 can be avoided.

[0120] Further, the baffle 4 can be provided with a certain curvature, and the condensed water formed outside the baffle 4 can also move along the baffle 4 and drip from the gap of the circumference, so that the condensed water outside the baffle 4 can also be naturally drained away; by adjusting the size of the gap, the condensed water on the baffle 4 can flow down along the side wall of the pot cover 2, and also carry away part of the condensed water on the side wall of the pot cover 2 during dripping, further improving the problem of residual condensed water in the pot cover 2 after work.

[0121] Further, a circular arc transition is provided at the edge position of the baffle 4 around the circumference, which is directed towards the center of the cavity, i.e. the food placement position. When the steam is discharged from the gap, the top steam can be guided to move towards the food by using the Coanda effect, so that the steam can be in contact with the food more quickly, thereby improving the cooking efficiency.

[0122] The steam baffle assembly is assembled in the interior of the pot cover 2 in a manner not limited, which can be detachable or non-detachable, and the fixed manner includes but is not limited to screws, buckles, welding, riveting, gluing, magnetic attraction, etc. The case provides a detachable mounting method as a reference, and the steam baffle assembly mainly includes two buckling positions, a spring, an upper cover, a baffle 4, and a lower cover. The spring is assembled between the two movable buckling positions, and when installed, the steam baffle assembly is pushed upwards, so that the buckling position is clamped into the slot position at the top of the pot cover 2 to fix the steam baffle 4 inside the pot cover 2; when cleaning after use, the steam baffle assembly can be directly pulled down, and the buckling position is detached from the slot position to remove the baffle 4, which is more conducive to user use. In addition, the baffle 4 in the steam baffle assembly in the case is of metal material, and in actual use, other materials such as plastic and glass can also be used.

[0123] In the scheme, the heating disc 32 is directly arranged inside the water tank 36, and steam is quickly generated by using the structure of the energy concentrating ring assembly. At the same time, the heating disc 32 is of an open structure, and after the energy concentrating ring assembly is removed, the scale and other problems on the surface of the heating disc 32 can be easily handled, the overall structure is simple, and the reliability is high. At the same time, by using the heating body assembly, the steam generated by the heating disc 32 can be secondarily heated to generate high-temperature steam with a temperature higher than 100℃, thereby improving the cooking rate. In actual use, other steam generation methods such as a steam generator can also be used, which can also achieve the effect of preventing the condensed water from dripping as described in the case.
