Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and more particularly, to a steam appliance. Background Art

[0002] At present, a large amount of steam is generated during the heating process of a steam appliance, and the pressure in the steam generation chamber will instantaneously increase. As a result, under the influence of the instantaneous increase in pressure and the violent boiling of water, a large amount of water will overflow from the steam outlet, affecting the cooking effect and causing the water level in the steam generation chamber to be unstable. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] To this end, the present invention provides a steam appliance.

[0005] In view of this, the present invention provides a steam appliance, comprising: a container including a water storage chamber; a steam generator including a steam generation chamber and a steam channel, the steam channel being provided on the top wall of the steam generation chamber and communicating with the steam generation chamber, the steam generation chamber being provided with a through hole, the steam channel being provided with a steam outlet, the through hole communicating with the water storage chamber; the water storage chamber being provided with a target water level line, wherein, relative to the bottom wall of the steam generation chamber, the top wall of the steam generation chamber is higher than the target water level line, and the distance between the top wall of the steam generation chamber and the target water level line is equal to a preset value.

[0006] The steam appliance provided by the present invention includes a container and a steam generator. The container includes a water storage chamber, and the steam generator is used to generate steam, and then the ingredients or articles are processed through the steam. The steam generator includes a steam generation chamber and a steam channel. The steam channel is provided on the top wall of the steam generation chamber and is communicated with the steam generation chamber. The steam in the steam generation chamber can gather into the steam channel and then be discharged through the steam outlet on the steam channel. The steam generation chamber is provided with a through hole, and the steam generation chamber is communicated with the water storage chamber through the through hole, so that the liquid in the water storage chamber can flow into the steam generation chamber through the through hole for the steam generation chamber to continuously generate steam. At the same time, when adding liquid to the steam generation chamber, the liquid in the steam generation chamber flows into the water storage chamber through the through hole, so that the liquid levels in the water storage chamber and the steam generation chamber are the same. Among them, the water storage chamber is provided with a target water level line for indicating to the user to add water into the container according to this target water level line. Relative to the bottom wall of the steam generation chamber, the top wall of the steam generation chamber is higher than the target water level line, and the height difference between the two is a preset value, which can avoid the situation that the pressure in the steam generation chamber instantaneously increases or the liquid violently boils, causing a large amount of water to overflow from the steam outlet, and further avoid a large amount of high-temperature liquid directly spraying onto the ingredients or articles, affecting the processing effect of the ingredients or articles. It can also avoid the situation that after a large amount of high-temperature liquid overflows, a large amount of low-temperature liquid floods into the steam generation chamber, resulting in a slowdown in the steam generation speed. That is, the present application ensures the steam output and the cooking effect by setting the water level line where the top wall of the steam generation chamber is located to be higher than the target water level line of the water storage chamber and making the difference between the two a preset value.

[0007] In specific applications, when the steam appliance is stable, that is, when no heating and boiling occur, relative to the bottom wall of the steam generation chamber, the top wall of the steam generation chamber is higher than the target water level line, and the distance between the top wall of the steam generation chamber and the target water level line is equal to the preset value.

[0008] It can be understood that the target water level line set on the water storage chamber indicates to the user that the water addition should not exceed this target water level line. For example, the user can add the liquid to the target water level line or below the target water level line. After adding the liquid into the container, the height of the actual water level line in the water storage chamber is the same as the height of the actual water level line in the steam generation chamber. That is, after the user adds the liquid according to the target water level line, the actual water level line in the steam generation chamber is the same as the actual water level line in the water storage chamber. Furthermore, the height of the water level line where the top wall of the steam generation chamber is located is higher than the height of the actual water level line in the steam generation chamber, and the difference between the two is the preset value. Therefore, it can avoid the situation that the liquid overflows from the steam outlet when the liquid violently boils or the pressure instantaneously increases.

[0009] Specifically, the water level line where the top wall of the steam generation chamber is located is the highest water level line of the steam generation chamber.

[0010] Optionally, the specific value of the preset value can be set according to the actual situation. For example, the preset value is greater than or equal to 10 mm, or the preset value is greater than or equal to 15 mm, or the preset value is greater than or equal to 20 mm.

[0011] Optionally, the cross-sectional area of the steam channel is smaller than the cross-sectional area of the steam generation chamber to achieve the convergence of steam.

[0012] According to the steam appliance provided by the present invention, the following additional technical features may also be included:

[0013] In some possible designs, the preset value is greater than or equal to 15 mm and less than or equal to 30 mm.

[0014] In this design, when the preset value is greater than or equal to 15 mm and less than or equal to 30 mm, if the difference between the water level line where the top wall of the steam generation chamber is located and the target water level line is too large, it will cause waste of the space inside the container. If the difference between the water level line where the top wall of the steam generation chamber is located and the target water level line is too small, it will cause the liquid to overflow from the steam outlet when the pressure value inside the steam generation chamber instantaneously increases or the liquid violently boils. Therefore, setting the preset value between 15 mm and 30 mm can not only improve the utilization rate of the space inside the container and reduce the manufacturing cost, but also avoid the liquid overflowing from the steam outlet.

[0015] In some possible designs, the height value of the target water level line relative to the bottom wall of the steam generation chamber is less than or equal to 2 / 3 of the height between the top wall and the bottom wall of the steam generation chamber.

[0016] In this design, if the target water level line is too high, it is easy to cause the liquid to overflow from the steam outlet when it violently boils, thereby affecting the cooking of the ingredients and the output of the steam. Therefore, the height value of the target water level line relative to the bottom wall of the steam generation chamber is less than or equal to 2 / 3 of the height between the top wall and the bottom wall of the steam generation chamber to avoid the situation where the liquid overflows from the steam outlet when it violently boils.

[0017] Specifically, when the steam appliance is stable, that is, when heating and boiling do not occur, the actual water level inside the cover body is less than or equal to 2 / 3 of the height from the bottom wall to the top wall of the steam generation chamber.

[0018] In some possible designs, the ratio of the cross-sectional area of the steam outlet to the cross-sectional area of the through hole is greater than or equal to 9:1 and less than or equal to 20:1.

[0019] In this design, if the ratio of the cross-sectional area of the steam outlet to the cross-sectional area of the through-hole is designed too large, the output speed of the steam will be reduced. If the ratio of the cross-sectional area of the steam outlet to the cross-sectional area of the through-hole is designed too small, the steam will be discharged from the through-hole. Therefore, the ratio of the cross-sectional area of the steam outlet to the cross-sectional area of the through-hole is designed to be greater than or equal to 9:1 and less than or equal to 20:1, which not only ensures the output speed of the steam but also avoids the situation where the steam is discharged from the through-hole.

[0020] In some possible designs, the diameter of the steam outlet is greater than or equal to 9 mm and less than or equal to 15 mm, and the diameter of the through-hole is greater than or equal to 1 mm and less than or equal to 5 mm.

[0021] In this design, if the diameter of the steam outlet is too large, the output speed of the steam will be reduced. If the diameter of the steam outlet is too small, the pressure in the steam generation chamber will be too high, which will cause the steam to be discharged from the through-hole. Therefore, the diameter of the steam outlet is set to be greater than or equal to 9 mm and less than or equal to 15 mm, and the diameter of the through-hole is greater than or equal to 1 mm and less than or equal to 5 mm, so as to increase the speed of the steam and form a micro-pressure environment in the steam generation chamber, which can not only ensure the output speed of the steam but also avoid the steam being discharged from the through-hole.

[0022] In specific applications, the diameter of the steam outlet is any value among 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, and 15 mm.

[0023] Optionally, the diameter of the through-hole is equal to any value among 1 mm, 2 mm, 3 mm, 4 mm, and 5 mm.

[0024] In some possible designs, the steam generator includes a cover body disposed inside the container. The cover body includes a steam generation chamber and a steam channel. The through-hole is located on the side wall of the cover body, and the steam outlet is located on the top wall of the cover body. The cover body and the inner wall surface of the container enclose a water storage chamber. Among them, the cross-sectional area of the steam channel is smaller than the cross-sectional area of the steam generation chamber.

[0025] In this design, the steam generator includes a cover body. The cover body includes a steam generation chamber and a steam channel. The cover body is disposed inside the container and encloses a water storage chamber with the inner wall surface of the container to realize automatic water replenishment for the steam generation chamber through the water storage chamber. Among them, the cross-sectional area of the steam channel is smaller than the cross-sectional area of the steam generation chamber, so that the size of the steam channel is reduced compared with the steam generation chamber. Therefore, the purpose of gathering steam is achieved, the output speed of the steam is increased, and the steam treatment of multiple steam trays or a disinfection area can be realized. In addition, setting the steam channel and reducing the cross-sectional area of the steam channel can further reduce the possibility of liquid overflow.

[0026] In some possible designs, the ratio of the cross-sectional area of the steam channel to the area of the top wall of the steam generation chamber is greater than or equal to 3% and less than or equal to 20%.

[0027] In this design, the size of the steam channel has a great influence on the discharge of steam. If the cross-sectional area of the steam channel is too large, the effect of gathering steam is poor, and the role in promoting steam discharge is low. If the cross-sectional area of the steam channel is too small, it is easy to cause the discharge speed to be too fast, and then bring out the boiling water, resulting in the situation of water spraying. Therefore, setting the ratio of the cross-sectional area of the steam channel to the area of the top wall of the steam generation chamber to be greater than or equal to 3% and less than or equal to 20% can not only ensure the promotion of steam discharge but also avoid the occurrence of water spraying.

[0028] In specific applications, the ratio of the cross-sectional area of the steam channel to the area of the top wall of the steam generation chamber is any ratio among 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, and 20%.

[0029] In some possible designs, the steam generator further includes: a heating component for heating the steam generation chamber; one end of the cover body opposite to the steam outlet is open, and the heating component is arranged at the open end of the cover body.

[0030] In this design, the heating component heats the steam generation chamber, causing the liquid in the steam generation chamber to evaporate, and then generating steam to process food ingredients through the steam. At the same time, the heating component only heats the steam generation chamber, reducing the amount of liquid heated and increasing the speed of steam generation, thereby achieving the effect of quickly generating steam. One end of the cover body opposite to the steam outlet is open. Arranging the heating component at the open end of the cover body not only seals one end of the cover body far from the steam outlet but also improves the heating efficiency of the liquid in the steam generation chamber.

[0031] In some possible designs, the heating component includes: a sealing plate arranged at the open end of the cover body and hermetically connected to the cover body; a heating element arranged at the end of the sealing plate facing away from the steam outlet.

[0032] In this design, the heating component includes a sealing plate and a heating element. The sealing plate is arranged at the open end of the cover body, closing the bottom of the steam generation chamber and preventing liquid leakage from the open end of the cover body. The heating element is arranged at the end of the sealing plate facing away from the steam outlet, which can not only heat the liquid but also avoid the occurrence of electric leakage caused by the heating element directly contacting the liquid.

[0033] Specifically, the wall surface of the sealing plate facing the steam generation chamber is the bottom wall of the steam generation chamber.

[0034] In some possible designs, the bottom of the cover body is sealingly connected to the bottom wall of the container.

[0035] In this design, the cover body is sealingly connected to the bottom wall of the container. Thus, the liquid in the cover body and the liquid in the water-containing cavity can only transfer heat through the cover body itself and the through hole, reducing the heat transfer between the liquid in the cover body and the liquid in the water-containing cavity and increasing the steam generation speed in the steam generation cavity.

[0036] Specifically, the cover body and the bottom wall of the container are of an integral structure, or the cover body and the bottom wall of the container are sealingly connected through a seal.

[0037] In some possible designs, a part of the bottom wall of the container bulges away from the heating component to form at least a part of the cover body.

[0038] In this design, a part of the bottom wall of the container bulges away from the heating component, thus forming at least a part of the cover body. That is, at least a part of the cover body and the container are of an integral structure, and at least a part of the cover body is a part of the container, improving the connection strength between the cover body and the container and eliminating the need to add a connection structure between the two to achieve their connection, simplifying the processing difficulty.

[0039] In some possible designs, the cover body includes: a first cover body provided on the bottom wall of the container, the first cover body being provided with a through hole; a second cover body detachably connected to the first cover body, the second cover body having a steam channel. When the second cover body is connected to the first cover body, the first cover body and the second cover body enclose a steam generation cavity.

[0040] In this design, the first cover body is arranged on the bottom wall of the container, and the second cover body is detachably connected to the first cover body. When the first cover body is connected to the second cover body, the first cover body and the second cover body enclose a steam generation cavity. The first cover body and the second cover body also enclose a water-containing cavity with the inner wall surface of the container. The heating component is used to supply heat to the steam generation cavity, thereby quickly generating steam to be discharged through the steam outlet to process food ingredients or articles. At the same time, the first cover body is provided with a through hole, enabling the steam generation cavity to communicate with the water-containing cavity through the through hole. Thus, the water-containing cavity can replenish water to the steam generation cavity to achieve continuous steam delivery. Among them, the first cover body and the second cover body are detachably connected. Therefore, when it is necessary to clean the steam appliance, the second cover body can be detached from the container, facilitating the cleaning of the container and the steam generation cavity and improving the cleaning effect.

[0041] In some possible designs, the second cover body includes: a cover body proper into which the first cover body can extend and which encloses a steam generation cavity with the first cover body; a contraction cylinder provided on the top wall of the cover body proper, the contraction cylinder including a steam channel, and the steam outlet being provided at one end of the contraction cylinder away from the cover body proper.

[0042] In this design, the second cover body includes a cover main body and a contraction cylinder. The first cover body can extend into the cover main body to realize the connection between the first cover body and the second cover body. At the same time, the first cover body and the cover main body enclose a steam generation chamber. The contraction cylinder is arranged on the top wall of the cover main body. The contraction cylinder includes a steam channel. The steam outlet is arranged on the contraction cylinder and is communicated with the steam channel. In this way, after the liquid in the steam generation chamber is heated, the steam flows through the steam channel to the steam outlet, and then flows through the steam outlet to the steaming tray or the disinfection chamber.

[0043] In some possible designs, at least part of the wall surface of the top wall of the steam generation chamber is an inclined surface. The inclined surface is annular along the circumference of the steam outlet, and the inclined surface inclines from the end close to the steam outlet to the end far from the steam outlet towards the bottom wall of the container.

[0044] In this design, at least part of the wall surface of the top wall of the steam generation chamber is an inclined surface. The inclined wall surface can reduce the volume of the steam generation chamber, and further reduce the liquid capacity in the steam generation chamber, so that the heating component heats a small amount of water, improving the steam generation speed. The inclined surface is annular along the circumference of the steam outlet, and the inclined surface inclines from the end close to the steam outlet to the end far from the steam outlet towards the bottom wall of the container, which is convenient for the manufacture of the cover body and reduces the processing difficulty.

[0045] In some possible designs, the steam appliance further includes: a water receiving tray, arranged at the top of the container. The water receiving tray is provided with a channel and a first water receiving groove. The first water receiving groove surrounds the channel. A part of the steam generator with a steam outlet extends into the channel.

[0046] In this design, the steam appliance further includes a water receiving tray. The water receiving tray is arranged at the top of the container. After the steam processes the food materials, condensed water will flow out. The first water receiving groove can receive the condensed water, preventing the condensed water from flowing into the water holding chamber or the steam generation chamber and affecting the steam volume. At the same time, the water receiving tray can also prevent the situation that the condensed water carries the smell of food materials or items and is evaporated again to cause odor mixing. Among them, a channel is arranged on the water receiving tray, and one end of the steam generator with a steam outlet extends into the channel, so that the steam outlet conveys steam upward through the channel.

[0047] In some possible designs, the water receiving tray further includes a second water receiving groove. The second water receiving groove is arranged in the first water receiving groove and is recessed from the first water receiving groove towards the container. The second water receiving groove surrounds the circumference of the steam generation chamber.

[0048] In this design, the water receiving tray further includes a second water receiving tank. In order to make the difference between the water level line where the top wall of the steam generating cavity is located and the target water level line be a preset value, the height of the steam generating cavity can be increased. After the height of the steam generating cavity is increased, it will occupy a relatively high space inside the container. Therefore, a second water receiving tank is arranged in the water receiving tray, so that the second water receiving tank surrounds the steam generating cavity, increasing the water receiving capacity of the water receiving tray.

[0049] In some possible designs, the steam appliance further includes: at least one processing unit, which is arranged on the top of the water receiving tray, and the steam outlet is communicated with the processing unit.

[0050] In this design, the steam appliance further includes at least one processing unit. The at least one processing unit is arranged on the top of the water receiving tray, and the steam outlet is communicated with the processing unit to realize steam processing of food ingredients or articles.

[0051] In some possible designs, the distance between the processing unit and the steam outlet is greater than or equal to 3 mm and less than or equal to 10 mm.

[0052] In this design, the distance between the processing unit and the steam outlet is greater than or equal to 3 mm and less than or equal to 10 mm, avoiding the influence on the steam processing effect due to the too large distance between the processing unit and the steam outlet.

[0053] In some possible designs, the steam appliance includes a steamer or a steam sterilizer.

[0054] In this design, the steam appliance includes a steamer or a steam sterilizer.

Detailed implementation manners

[0064] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0065] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0066] Next, refer to Figures 1 to 5 Describe a steam electrical appliance according to some embodiments of the present invention.

[0067] As Figures 1 to 5 shown, according to an embodiment of the present invention, the present invention provides a steam electrical appliance, including: a container 1 and a steam generator 2.

[0068] Specifically, the container 1 includes a water holding cavity 10; the steam generator 2 includes a steam generation cavity 20 and a steam channel 21. The steam channel 21 is provided on the top wall 202 of the steam generation cavity 20 and is communicated with the steam generation cavity 20. The steam generation cavity 20 is provided with a through hole 200, and the steam channel 21 is provided with a steam outlet 210. The through hole 200 is communicated with the water holding cavity 10; the water holding cavity 10 is provided with a target water level line. Among them, relative to the bottom wall of the steam generation cavity 20, the top wall 202 of the steam generation cavity 20 is higher than the target water level line, and the distance between the top wall 202 of the steam generation cavity 20 and the target water level line is equal to a preset value.

[0069] The steam appliance provided by the present invention includes a container 1 and a steam generator 2. The container 1 includes a water storage chamber 10. The steam generator 2 is used to generate steam, and then the ingredients or articles are processed by the steam. The steam generator 2 includes a steam generation chamber 20 and a steam channel 21 that are connected and communicated. The steam channel 21 is provided on the top wall 202 of the steam generation chamber 20. The steam generated in the steam generation chamber 20 can gather in the steam channel 21 and then flow out from the steam outlet 210 on the steam channel 21. A through hole 200 is provided on the steam generation chamber 20. The steam generation chamber 20 is communicated with the water storage chamber 10 through the through hole 200, so that the liquid in the water storage chamber 10 can flow into the steam generation chamber 20 through the through hole 200 to supply the steam generation chamber 20 to continuously generate steam. At the same time, when adding liquid to the steam generation chamber 20, the liquid in the steam generation chamber 20 flows into the water storage chamber 10 through the through hole 200, so that the liquid levels in the water storage chamber 10 and the steam generation chamber 20 are the same. Wherein, the water storage chamber 10 is provided with a target water level line for indicating to the user to add water into the container 1 according to this target water level line. Relative to the bottom wall of the steam generation chamber 20, the top wall 202 of the steam generation chamber 20 is higher than the target water level line, and the height difference between the two is a preset value, which can avoid the situation that the pressure in the steam generation chamber 20 instantaneously increases or the liquid violently boils, causing a large amount of water to overflow from the steam outlet 210, thereby avoiding a large amount of high-temperature liquid directly spraying onto the ingredients or articles and affecting the processing effect of the ingredients or articles. It can also avoid the situation that after a large amount of high-temperature liquid overflows, a large amount of low-temperature liquid surges into the steam generation chamber 20, resulting in a slowdown in the steam generation speed. That is, in this application, by setting the water level line where the top wall 202 of the steam generation chamber 20 is located to be higher than the target water level line of the water storage chamber 10 and making the difference between the two a preset value, the steam output and the cooking effect are guaranteed.

[0070] It should be noted that the top wall 202 and the bottom wall of the steam generation chamber 20 are two opposite wall surfaces of the steam generation chamber 20 in the vertical direction.

[0071] It can be understood that the target water level line set on the water storage chamber 10 indicates that the user cannot add water exceeding this target water level line. For example, the user can add the liquid to the target water level line or below the target water level line. After adding the liquid into the container 1, the height of the actual water level line in the water storage chamber 10 is the same as the height of the actual water level line in the steam generation chamber 20. That is, after the user adds the liquid according to the target water level line, the actual water level line in the steam generation chamber 20 is the same as the actual water level line in the water storage chamber 10. Furthermore, the height of the water level line where the top wall 202 in the steam generation chamber 20 is located is higher than the height of the actual water level line in the steam generation chamber 20, and the difference between the two is a preset value. Therefore, the situation that the liquid overflows from the steam outlet 210 when the liquid violently boils or the pressure instantaneously increases can be avoided.

[0072] Specifically, the water level line where the top wall 202 of the steam generation chamber 20 is located is the highest water level line of the steam generation chamber 20.

[0073] Optionally, the specific value of the preset value can be set according to the actual situation. For example, the preset value is greater than or equal to 10 mm, or the preset value is greater than or equal to 15 mm, or the preset value is greater than or equal to 20 mm.

[0074] Optionally, the cross-sectional area of the steam channel 21 is smaller than the cross-sectional area of the steam generation chamber 20 to achieve the gathering of steam.

[0075] Specifically, Figure 1 shows a schematic diagram of a steam appliance according to an embodiment of the present application, Figure 2 shows a schematic diagram of a steam appliance according to another embodiment of the present application, Figure 3 shows a schematic diagram of a steam appliance according to still another embodiment of the present application, Figure 4 shows a partial structural schematic diagram of a steam appliance according to an embodiment of the present application, wherein, Figure 4 shows a possible setting position of the target water level line, but is not limited to this position.

[0076] According to some embodiments of the present application, optionally, the preset value is greater than or equal to 15 mm and less than or equal to 30 mm.

[0077] In this embodiment, when the preset value is greater than or equal to 15 mm and less than or equal to 30 mm, if the difference between the water level line where the top wall 202 of the steam generation chamber 20 is located and the target water level line is too large, it will cause waste of the space inside the container 1. If the difference between the water level line where the top wall 202 of the steam generation chamber 20 is located and the target water level line is too small, it will cause the liquid to overflow from the steam outlet 210 when the pressure value in the steam generation chamber 20 instantaneously increases or the liquid violently boils. Therefore, setting the preset value between 15 mm and 30 mm can not only improve the utilization rate of the space inside the container 1, reduce the manufacturing cost, but also avoid the liquid from overflowing from the steam outlet 210.

[0078] In specific applications, the preset value is equal to any value among 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm.

[0079] According to some embodiments of the present application, optionally, the height value of the target water level line relative to the bottom wall of the steam generation chamber 20 is less than or equal to 2 / 3 of the height between the top wall 202 and the bottom wall of the steam generation chamber 20.

[0080] In this embodiment, if the target water level line is too high, it is easy for the liquid to overflow from the steam outlet 210 during violent boiling, which will affect the cooking of the ingredients and the output of the steam. Therefore, the height value of the target water level line relative to the bottom wall of the steam generation chamber 20 is less than or equal to 2 / 3 of the height between the top wall 202 of the steam generation chamber 20 and the bottom wall, so as to avoid the situation that the liquid overflows from the steam outlet 210 during violent boiling.

[0081] Specifically, when the steam appliance is stable, that is, when heating and boiling do not occur, the actual water level in the cover body 22 is less than or equal to 2 / 3 of the height from the bottom wall of the steam generation chamber 20 to the top wall 202 of the steam generation chamber 20.

[0082] According to some embodiments of the present application, optionally, the ratio of the cross-sectional area of the steam outlet 210 to the cross-sectional area of the through hole 200 is greater than or equal to 9:1 and less than or equal to 20:1.

[0083] In this embodiment, if the ratio of the cross-sectional area of the steam outlet 210 to the cross-sectional area of the through hole 200 is designed too large, the output speed of the steam will be reduced. If the ratio of the cross-sectional area of the steam outlet 210 to the cross-sectional area of the through hole 200 is designed too small, the steam will be discharged from the through hole 200. Therefore, the cross-sectional area of the steam outlet 210 and the cross-sectional area of the through hole 200 are designed to be greater than or equal to 9:1 and less than or equal to 20:1, which not only ensures the output speed of the steam but also avoids the situation that the steam is discharged from the through hole 200.

[0084] In specific applications, if the ratio of the cross-sectional area of the steam outlet 210 to the cross-sectional area of the through hole 200 is any value among 9:1, 10:1, 11:1, 12:1, 13:1, 14:1, 15:1, 16:1, 17:1, 18:1, 19:1, 20:1, it can improve the cooking efficiency.

[0085] According to some embodiments of the present application, optionally, the diameter of the steam outlet 210 is greater than or equal to 9 mm and less than or equal to 15 mm, and the diameter of the through hole 200 is greater than or equal to 1 mm and less than or equal to 5 mm.

[0086] In this embodiment, if the diameter of the steam outlet 210 is too large, the output speed of the steam will be reduced. If the diameter of the steam outlet 210 is too small, the pressure in the steam generation chamber 20 will be too high, resulting in the steam being discharged from the through hole 200. Therefore, the diameter of the steam outlet 210 is set to be greater than or equal to 9 mm and less than or equal to 15 mm, and the diameter of the through hole 200 is greater than or equal to 1 mm and less than or equal to 5 mm to accelerate the steam, so as to form a micro-pressure environment in the steam generation chamber 20, which can not only ensure the output speed of the steam but also avoid the steam being discharged from the through hole 200.

[0087] In a specific application, the diameter of the steam outlet 210 is any value among 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, and 15 mm.

[0088] Optionally, the diameter of the through hole 200 is equal to any value among 1 mm, 2 mm, 3 mm, 4 mm, and 5 mm.

[0089] As Figure 1 shown, according to some embodiments of the present application, optionally, a steam channel 21 is further provided in the cover body 22. The steam channel 21 is provided on the top wall 202 of the steam generation chamber 20 and communicates with the steam generation chamber 20. The steam outlet 210 is provided at the top of the steam channel 21. The cover body 22 and the inner wall surface of the container 1 enclose a water storage chamber 10; wherein, the cross-sectional area of the steam channel 21 is smaller than the cross-sectional area of the steam generation chamber 20.

[0090] As Figure 1 shown, according to some embodiments of the present application, optionally, the steam generator 2 includes: a cover body 22, which is arranged in the container 1. The cover body 22 includes a steam generation chamber 20 and a steam channel 21. The through hole 200 is located on the side wall of the cover body 22, and the steam outlet 210 is located on the top wall of the cover body 22. The cover body 22 and the inner wall surface of the container 1 enclose a water storage chamber 10; in this embodiment, the cover body 22 and the inner wall surface of the container 1 enclose a water storage chamber 10. The steam generator 2 includes a cover body 22, and the cover body 22 includes a steam generation chamber 20 and a steam channel 21. The cover body 22 is arranged in the container 1 and encloses a water storage chamber 10 with the inner wall surface of the container 1 to automatically replenish water to the steam generation chamber 20 through the water storage chamber 10. Wherein, the cross-sectional area of the steam channel 21 is smaller than the cross-sectional area of the steam generation chamber 20, so that the size of the steam channel 21 is reduced compared with the steam generation chamber 20. Therefore, the purpose of gathering steam is achieved, the steam output speed is increased, and then the steam treatment of the multi-layer steam tray 40 or the disinfection area can be realized. In addition, by providing the steam channel 21 and reducing the cross-sectional area of the steam channel 21, the possibility of liquid overflow can be further reduced.

[0091] It can be understood that the cross-sectional area of the steam channel 21 is the cross-section of the steam channel 21 perpendicular to the vertical direction, and the cross-sectional area of the steam generation chamber 20 is the cross-section of the steam generation chamber 20 perpendicular to the vertical direction. That is, along the steam flow direction, the steam channel 21 contracts compared with the steam generation chamber 20 to achieve the effect of gathering steam.

[0092] It can be understood that the setting of the cover 22 can divide the space in the container 1 into two areas, namely a steam generation chamber 20 and a water storage chamber 10. The heating assembly 23 supplies heat to the liquid in the steam generation chamber 20. Compared with the heating assembly 23 supplying heat to all the water in the steam generation chamber 20 and the water storage chamber 10, the amount of water heated by the heating assembly 23 is reduced. Therefore, when heating a small amount of water in the steam generation chamber 20, the water in the steam generation chamber 20 can boil quickly, and then steam can be generated quickly. The steam generation chamber 20 and the water storage chamber 10 are connected through a through hole 200. While realizing the water replenishment of the steam generation chamber 20, the water outside the steam generation chamber 20 can only exchange heat through the surface of the cover 22 and the through hole 200, so as to achieve the effect that the water in the water storage chamber 10 does not boil while the water in the steam generation chamber 20 boils quickly, and the speed of steam generation is improved.

[0093] In a specific application, a certain amount of liquid is injected into the steam generation chamber 20. The liquid in the steam generation chamber 20 flows through the through hole 200 to the water storage chamber 10, and finally the liquid reaches the same liquid level in the water storage chamber 10 and the steam generation chamber 20.

[0094] It should be noted that the outer wall surface of the cover 22 and the inner wall surface of the container 1 enclose the water storage chamber 10.

[0095] Optionally, the cover 22 and the container 1 are of an integral structure. The cover 22 can also be of a split structure with the container 1, or the cover 22 is divided into a first cover 220 and a second cover 222. The first cover 220 is of an integral structure with the container 1, and the second cover 222 is detachably connected to the first cover 220.

[0096] According to some embodiments of the present application, optionally, the ratio of the cross-sectional area of the steam channel 21 to the area of the top wall 202 of the steam generation chamber 20 is greater than or equal to 3% and less than or equal to 20%.

[0097] In this embodiment, the size of the steam channel 21 has a great influence on the discharge of steam. If the cross-sectional area of the steam channel 21 is too large, the effect of gathering steam is poor, and the role in promoting steam discharge is low. If the cross-sectional area of the steam channel 21 is too small, it is easy to cause the discharge speed to be too fast, and then the boiling water is carried out, resulting in a water spraying situation. Therefore, setting the ratio of the cross-sectional area of the steam channel 21 to the area of the top wall 202 of the steam generation chamber 20 to be greater than or equal to 3% and less than or equal to 20% can not only ensure the promotion of steam discharge but also avoid the occurrence of water spraying.

[0098] In a specific application, the ratio of the cross-sectional area of the steam passage 21 to the area of the top wall 202 of the steam generation chamber 20 is any ratio among 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, and 20%.

[0099] As Figure 4 shown, according to some embodiments of the present application, optionally, the steam generator 2 further includes: a heating assembly 23 for heating the steam generation chamber 20; one end of the cover 22 opposite to the steam outlet 210 is open, and the heating assembly 23 is disposed at the open end of the cover 22.

[0100] In this embodiment, the heating assembly 23 heats the steam generation chamber 20, so that the liquid in the steam generation chamber 20 evaporates, and then steam is generated to process food materials through the steam. At the same time, the heating assembly 23 only heats the steam generation chamber 20, reducing the amount of heated liquid, increasing the speed of steam generation, and thus achieving the effect of quickly generating steam. One end of the cover 22 opposite to the steam outlet 210 is open. The heating assembly 23 is disposed at the open end of the cover 22, which on the one hand closes the end of the cover 22 far from the steam outlet 210, and on the other hand improves the heating efficiency of the liquid in the steam generation chamber 20.

[0101] According to some embodiments of the present application, optionally, the heating assembly 23 includes: a sealing plate 230 disposed at the open end of the cover 22 and sealingly connected to the cover 22; a heating element 232 disposed at the end of the sealing plate 230 facing away from the steam outlet 210.

[0102] In this embodiment, the heating assembly 23 includes a sealing plate 230 and a heating element 232. The sealing plate 230 is disposed at the open end of the cover 22, closing the bottom of the steam generation chamber 20 and preventing liquid leakage from the open end of the cover 22. The heating element 232 is disposed at the end of the sealing plate 230 facing away from the steam outlet 210, which can avoid the occurrence of electric leakage caused by the direct contact between the heating element 232 and the liquid while realizing liquid heating.

[0103] According to some embodiments of the present application, optionally, the bottom of the cover 22 is sealingly connected to the bottom wall of the container 1.

[0104] In this embodiment, the cover 22 is sealingly connected to the bottom wall of the container 1. Thus, the liquid in the cover 22 and the liquid in the water storage chamber 10 can only transfer heat through the cover 22 itself and the through hole 200, reducing the heat transfer between the liquid in the cover 22 and the liquid in the water storage chamber 10 and increasing the steam generation speed in the steam generation chamber 20.

[0105] Specifically, the cover body 22 and the bottom wall of the container 1 are of an integral structure, or the cover body 22 and the bottom wall of the container 1 are sealingly connected through a seal.

[0106] As Figure 4 shown, according to some embodiments of the present application, optionally, a part of the bottom wall of the container 1 bulges away from the heating component 23 to form at least a part of the cover body 22.

[0107] In this embodiment, a part of the bottom wall of the container 1 bulges away from the heating component 23, thereby forming at least a part of the cover body 22. That is to say, at least a part of the cover body 22 and the container 1 are of an integral structure, and at least a part of the cover body 22 is a part of the container 1, which improves the connection strength between the cover body 22 and the container 1, and there is no need to add a connection structure between the two to realize their connection, simplifying the processing difficulty.

[0108] In a specific application, when the cover body 22 includes a first cover body 220 and a second cover body 222, a part of the bottom wall of the container 1 bulges upward to form the first cover body 220.

[0109] As Figure 2 and Figure 3 shown, according to some embodiments of the present application, optionally, the cover body 22 includes: a first cover body 220 provided on the bottom wall of the container 1, and the first cover body 220 is provided with a through hole 200; a second cover body 222 detachably connected to the first cover body 220, and the second cover body 222 has a steam channel 21. When the second cover body 222 is connected to the first cover body 220, the first cover body 220 and the second cover body 222 enclose a steam generation chamber 20.

[0110] In this embodiment, the first cover body 220 is arranged on the bottom wall of the container 1, and the second cover body 222 is detachably connected to the first cover body 220. When the first cover body 220 is connected to the second cover body 222, the first cover body 220 and the second cover body 222 enclose a steam generation chamber 20. The first cover body 220 and the second cover body 222 also enclose a water storage chamber 10 with the inner wall surface of the container 1. The heating component 23 is used to supply heat to the steam generation chamber 20, so as to quickly generate steam, and the steam is discharged through the steam outlet 210 to realize the processing of food ingredients or articles. At the same time, the first cover body 220 is provided with a through hole 200, so that the steam generation chamber 20 can communicate with the water storage chamber 10 through the through hole 200, and thus the water storage chamber 10 can replenish water for the steam generation chamber 20 to realize the continuous delivery of steam. Among them, the first cover body 220 and the second cover body 222 are detachably connected. Therefore, when it is necessary to clean the steam appliance, the second cover body 222 can be detached from the container 1, which is convenient for cleaning the container 1 and the steam generation chamber 20 and improves the cleaning effect.

[0111] Optionally, the through hole 200 is provided on the side wall of the first cover 220.

[0112] Optionally, the steam outlet 210 is provided at the top of the second cover 222.

[0113] Optionally, according to some embodiments of the present application, optionally, when the second cover 222 is connected to the first cover 220, one of the first cover 220 and the second cover 222 extends into the other.

[0114] In this embodiment, when the second cover 222 is connected to the first cover 220, one of the first cover 220 and the second cover 222 extends into the other to realize the connection between the first cover 220 and the second cover 222, improving the sealing performance of the connection between the first cover 220 and the second cover 222, and thus reducing the heat exchange amount between the liquid in the steam generation chamber 20 and the liquid in the water storage chamber 10, ensuring the steam generation efficiency.

[0115] Optionally, a part of the first cover 220 extends into the second cover 222 to realize the connection between the first cover 220 and the second cover 222.

[0116] According to some embodiments of the present application, optionally, a first sealing ring and a second sealing ring are provided in the second cover 222, and the first sealing ring is located inside the second sealing ring; when the first cover 220 and the second cover 222 are connected, at least a part of the first cover 220 extends into the second cover 222, and the first sealing ring and the second sealing ring are located on both sides of the first cover 220 and contact the first cover 220.

[0117] In this embodiment, a first sealing ring and a second sealing ring are provided in the second cover 222, and the first sealing ring is located inside the second sealing ring. Among them, when the first cover 220 and the second cover 222 are connected, at least a part of the first cover 220 extends into the second cover 222 to realize the connection between the first cover 220 and the second cover 222, increasing the contact area between the first cover 220 and the second cover 222, and thus improving the sealing performance at the connection between the first cover 220 and the second cover 222. The first sealing ring and the second sealing ring are located on both sides of the first cover 220 and contact the first cover 220, thereby realizing the sealing at the connection between the first cover 220 and the second cover 222 and reducing the heat exchange amount between the liquid in the steam generation chamber 20 and the liquid in the water storage chamber 10.

[0118] Optionally, the first sealing ring contacts the inner wall surface of the first cover 220, and the second sealing ring contacts the outer wall surface of the first cover 220.

[0119] According to some embodiments of the present application, optionally, a rib is provided on one side of the first sealing ring facing the first cover body 220, and the first sealing ring contacts the first cover body 220 through the rib.

[0120] In this embodiment, a rib is provided on one side of the first sealing ring facing the first cover body 220, and the first sealing ring contacts the first cover body 220 through the rib, realizing the sealing between the first cover body 220 and the second cover body 222, and reducing the resistance during the assembly process of the first cover body 220 and the second cover body 222.

[0121] It can be understood that the rib is annular.

[0122] According to some embodiments of the present application, optionally, the second cover body 222 includes: a cover body 223, the first cover body 220 can extend into the cover body 223, and together with the cover body 223 enclose a steam generation chamber 20; a contraction cylinder 224, the contraction cylinder 224 is provided on the top wall of the cover body 223, the contraction cylinder 224 includes a steam channel 21, and a steam outlet 210 is provided at one end of the contraction cylinder 224 away from the cover body 223.

[0123] In this embodiment, the second cover body 222 includes a cover body 223 and a contraction cylinder 224. The first cover body 220 can extend into the cover body 223 to realize the connection between the first cover body 220 and the second cover body 222. At the same time, the first cover body 220 and the cover body 223 enclose a steam generation chamber 20. The contraction cylinder 224 is provided on the top wall of the cover body 223. The contraction cylinder 224 includes a steam channel 21, and a steam outlet 210 is provided on the contraction cylinder 224 and communicates with the steam channel 21. In this way, after the liquid in the steam generation chamber 20 is heated, the steam flows through the steam channel 21 to the steam outlet 210, and then flows through the steam outlet 210 to the steaming tray 40 or the disinfection chamber.

[0124] Optionally, the cover body 223 and the contraction cylinder 224 are of an integral structure.

[0125] Optionally, as Figures 2 to 4 shown, a handle 225 is provided on the outer side wall of the second cover body 222.

[0126] Optionally, the handle 225 may not be provided on the outer side wall of the second cover body 222.

[0127] As Figure 3 shown, according to some embodiments of the present application, optionally, at least part of the top wall 202 of the steam generation chamber 20 is an inclined surface 204. The inclined surface 204 is annular along the circumference of the steam outlet 210, and the inclined surface 204 inclines from one end close to the steam outlet 210 to one end away from the steam outlet 210 towards the bottom wall of the container 1.

[0128] In this embodiment, at least a part of the top wall 202 of the steam generation chamber 20 is an inclined surface 204. The inclined wall surface can reduce the volume of the steam generation chamber 20, thereby reducing the liquid capacity in the steam generation chamber 20, so that the heating assembly 23 heats a small amount of water, improving the steam generation speed. The inclined surface 204 is annular along the circumference of the steam outlet 210, and the inclined surface 204 inclines from the end close to the steam outlet 210 to the end far from the steam outlet 210 towards the bottom wall of the container 1, which is convenient for the manufacture of the cover body 22 and reduces the processing difficulty.

[0129] Optionally, the inclined surface 204 is inclined relative to the vertical direction.

[0130] Optionally, a part of the top wall of the cover body 223 is a flat surface, and a part of the wall surface is an inclined surface 204, and the inclined surface 204 is located around the flat surface.

[0131] As Figures 1 to 3 shown, according to some embodiments of the present application, optionally, the steam electrical appliance further includes: a water receiving tray 3, disposed on the top of the container 1. The water receiving tray 3 is provided with a channel 30 and a first water receiving groove 32. The first water receiving groove 32 surrounds the channel 30, and a part of the steam generator 2 provided with the steam outlet 210 extends into the channel 30.

[0132] In this embodiment, the steam electrical appliance further includes a water receiving tray 3. The water receiving tray 3 is disposed on the top of the container 1. After the steam processes the food materials, condensed water will flow out. The first water receiving groove 32 can receive the condensed water, preventing the condensed water from flowing into the water storage chamber 10 or the steam generation chamber 20 and affecting the steam volume. At the same time, the water receiving tray 3 can also prevent the situation that the condensed water carries the smell of food materials or items and is evaporated again, resulting in odor mixing. Among them, a channel 30 is provided on the water receiving tray 3, and one end of the steam generator 2 provided with the steam outlet 210 extends into the channel 30, so that the steam outlet 210 conveys steam upward through the channel 30.

[0133] As Figure 2 shown, according to some embodiments of the present application, optionally, the water receiving tray 3 further includes a second water receiving groove 34. The second water receiving groove 34 is disposed in the first water receiving groove 32 and is recessed from the first water receiving groove 32 towards the container 1. The second water receiving groove 34 surrounds the circumference of the steam generation chamber 20.

[0134] In this embodiment, the water receiving tray 3 further includes a second water receiving groove 34. In order to make the difference between the water level line where the top wall 202 of the steam generation chamber 20 is located and the target water level line be a preset value, the height of the steam generation chamber 20 can be increased. However, after the height of the steam generation chamber 20 is increased, it will occupy a relatively high space in the container 1. Therefore, a second water receiving groove 34 is further provided in the water receiving tray 3, so that the second water receiving groove 34 surrounds the steam generation chamber 20, increasing the water receiving capacity of the water receiving tray 3.

[0135] As Figures 1 to 3 shown, according to some embodiments of the present application, optionally, the steam appliance further includes: at least one processing unit 4, disposed on the top of the water receiving tray 3, and the steam outlet 210 is in communication with the processing unit 4.

[0136] In this embodiment, the steam appliance further includes at least one processing unit 4. The at least one processing unit 4 is disposed on the top of the water receiving tray 3, and the steam outlet 210 is in communication with the processing unit 4 to achieve steam processing of food ingredients or articles.

[0137] In a specific application, the processing unit 4 includes a steaming tray 40 and a steaming cover 42. The steaming tray 40 is provided with through holes for steam to pass through. The steaming cover 42 at least surrounds the steaming tray 40 to enclose a cooking cavity with the steaming tray 40 to achieve steaming of food ingredients. In the case where there are multiple processing units 4, the multiple processing units 4 are arranged in sequence in the vertical direction, and the steaming cover 42 of the processing unit 4 located at the top covers the corresponding steaming tray 40.

[0138] In another specific application, the processing unit 4 includes a disinfection cavity. The disinfection cavity has a steam inlet, and the steam outlet 210 is in communication with the disinfection cavity through the steam inlet to achieve disinfection of the articles in the disinfection cavity.

[0139] According to some embodiments of the present application, optionally, the distance between the processing unit 4 and the steam outlet 210 is greater than or equal to 3 mm and less than or equal to 10 mm.

[0140] In this embodiment, the distance between the processing unit 4 and the steam outlet 210 is greater than or equal to 3 mm and less than or equal to 10 mm, avoiding an excessive distance between the processing unit 4 and the steam outlet 210 that may affect the steam processing effect.

[0141] In a specific application, the distance between the processing unit 4 and the steam outlet 210 is any value among 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm.

[0142] According to some embodiments of the present application, optionally, the steam appliance includes a steamer or a steam sterilizer.

[0143] In this embodiment, the steam appliance includes a steamer or a steam sterilizer.

[0144] Optionally, the cooking appliance further includes a water holding tray, and the water holding tray includes a container 1.

[0145] In a specific application, during use, a certain amount of water is filled into the steam generation chamber 20. When the water fills the steam generation chamber 20, the excess water will drain out of the steam generation chamber 20 along the water injection holes (such as the through hole 200) inside the steam generation chamber 20, and the added water will ultimately reach the same water level inside and outside the steam generation chamber 20. Through sealing with an energy-gathering ring (such as the cover body 22), the water capacity in the water tray can be controlled, and the heat loss of the water inside the energy-gathering ring can be reduced. After starting heating, the water in the steam generation chamber 20 will boil relatively faster to generate a large amount of steam. At the same time, by reducing the aperture of the water injection hole, the heat exchange of the water inside and outside the energy-gathering ring can be reduced. During the heating process, a large amount of steam is generated, and the pressure inside the energy-gathering ring will increase instantaneously, so a large amount of steam will be discharged from the steam outlet 210 of the energy-gathering ring, and a small amount of steam will also be discharged from the water injection hole. In order to make the steam escape as little as possible from the water injection hole and at the same time avoid the rapid reduction of the water inside the energy-gathering ring due to the instantaneous increase in pressure inside the energy-gathering ring, in the existing structure, it is necessary to ensure that the area ratio of the steam outlet 210 of the energy-gathering ring to the water injection hole is greater than or equal to 9:1 (optionally, the area ratio of the steam outlet 210 to the water injection hole is greater than or equal to 3:1). In the existing structure, in order to keep the water level inside the energy-gathering ring stable and avoid a large amount of water overflowing from the steam outlet 210 of the energy-gathering ring due to the instantaneous increase in pressure inside the energy-gathering ring and the violent boiling of the water, the height of the highest liquid level line of the energy-gathering ring is more than 15 mm higher than the actual water level line inside the energy-gathering ring. In the existing structure, in order to prevent water from overflowing from the steam outlet 210 of the energy-gathering ring, the height of the highest liquid level of the energy-gathering ring is increased by 15 mm, and at the same time, the diameter of the smoke-gathering buffer area (such as the contraction cylinder 224) of the energy-gathering ring is reduced to achieve the purpose of gathering steam, and the water capacity inside the energy-gathering ring can also be reduced. At the same time, the area of the steam outlet 210 is designed as a round hole with a diameter controlled above 9 mm to achieve the speed increase of the steam and create a micro-pressure environment inside the energy-gathering ring. Optionally, a round hole with a diameter of 13 mm is used as the steam outlet. When a round hole with a diameter of 3 mm is used as the water injection hole, stable steam output can be achieved, and the cooking time can be shortened. As Figure 5 shown, during the actual test process, under the condition that the distance between the lowest point of the bottom surface of the steaming tray 40 and the upper surface of the steam outlet 210 is greater than 3 mm, when the area ratio of the water injection hole to the steam outlet 210 is 1:3 (specifically, the area ratio of the steam outlet 210 to the water injection hole is greater than or equal to 9:1), the performance reaches a stable state. By comparing the central temperature of the top steaming tray 40 for comparison tests, the optimized steamer will have a faster temperature efficiency than the ordinary steamer. Taking 90 °C as the benchmark, the optimized steamer is 382 s faster than the traditional steamer, greatly accelerating the cooking efficiency of the steamer and providing a good user experience for some foods with short cooking times.

[0146] In the present invention, the term "a plurality of" means two or more, unless otherwise clearly defined. Terms such as "installed", "connected", "coupled", "fixed", etc. should be understood in a broad sense.
