Description

Technical Field

[0001] This application belongs to the technical field of household appliances, and particularly relates to a steam device, a high-temperature steam oven, and a cooking method for the high-temperature steam oven. Background Art

[0002] At present, ordinary steamers on the market generally generate steam by heating water with an electric heating plate and then delivering the steam to the inner cavity of the steamer. The steam temperature is basically around 100°C. When steaming food, the actual steam temperature will be lower than 100°C due to heat consumption, resulting in a slow speed of steaming food. At the same time, a large amount of condensed water will be generated. Therefore, not only is the heating efficiency low, but also the taste of the steamed food is poor. In view of the above problems, Chinese Patent Application No. CN 113317675 A discloses a multi-stage heating high-temperature steam multi-functional steam pot. Water enters the steam generator inlet to generate 100°C steam, and then passes through a secondary high-temperature steam heating device to generate high-temperature steam above 100°C. The steam outlet of the secondary high-temperature steam heating device sprays high-temperature steam from the bottom of the steam baking tray into the steamer cavity to achieve the high-temperature steaming function above 100°C under normal pressure. However, since the steam has to be dispersed throughout the inner cavity of the steamer to steam the food materials, it is difficult to continuously maintain the actual temperature of the steam in the inner cavity at 100°C, and the purpose of quickly steaming the food cannot be achieved. Summary of the Invention

[0003] In view of the above problems existing in the prior art, the purpose of the embodiments of this application is to provide a steam device, a high-temperature steam oven, and a cooking method for the high-temperature steam oven. The steam device is provided with a plurality of steam outlets so as to adjust the opening and closing of the steam outlets according to cooking requirements, enabling the high-temperature steam to directly act on the food materials or fill the entire cooking cavity, thereby realizing different cooking modes.

[0004] The technical solution adopted in the embodiments of this application is a steam device for a high-temperature steam oven. The steam device includes one steam generator or a plurality of steam generators connected in sequence for multi-stage evaporation. The last-stage steam generator of the one steam generator or the plurality of steam generators has a plurality of steam outlets, and the plurality of steam outlets are respectively communicated to the same or different cooking areas in the cooking cavity of the high-temperature steam oven to respectively or simultaneously send high-temperature steam into the cooking cavity. Among them, the plurality of steam outlets include at least one first steam outlet directly communicated with the cooking area and at least one second steam outlet capable of switching between closing and opening.

[0005] In some embodiments, there is one first steam outlet, which is arranged corresponding to the first cooking area at the highest position in the cooking cavity, so that the high-temperature steam is directly sprayed into the first cooking area. By setting the first steam outlet to one, the spraying speed of the high-temperature steam is faster, which is more conducive to achieving the effect of rapid steaming.

[0006] In some embodiments, there are multiple second steam outlets, and the multiple second steam outlets are simultaneously communicated with different cooking areas or the same cooking area of the cooking cavity. In this way, a large amount of high-temperature steam can enter the cooking cavity simultaneously and quickly spread to fill all cooking areas, realizing the simultaneous steaming of a large amount of food.

[0007] In some embodiments, a steam valve is provided at the second steam outlet. The steam valve includes a valve body and a valve core. A valve cavity is provided in the valve body. The valve core is arranged in the valve cavity and can reciprocate along the valve cavity under the action of an external force to close or open the second steam outlet. The structure of this steam valve is simple and reasonable, and it is convenient to manufacture.

[0008] In some embodiments, the steam valve further includes a reset member, and the reset member acts on the valve core;

[0009] The valve core includes an iron core and a sealing portion provided at one end of the iron core;

[0010] The valve body includes an iron core seat and an electromagnet provided outside the iron core seat. The valve cavity is formed in the iron core seat, and a valve port communicating with the valve cavity is provided on the iron core seat. The valve cavity can be simultaneously communicated with the second steam outlet and the cooking cavity through the valve port;

[0011] When the electromagnet is energized, it adsorbs the iron core and drives the sealing portion to move away from the second steam outlet to open the second steam outlet; when the electromagnet is de-energized, the iron core drives the sealing portion to move towards the second steam outlet under the action of the reset member to close the second steam outlet. By energizing and de-energizing the electromagnet, the opening and closing of the second steam outlet can be controlled, realizing automatic control.

[0012] In some embodiments, the steam device further includes a sealing plug, and the sealing plug is arranged on the steaming tray of the high-temperature steaming oven. When the steaming tray is placed in the cooking cavity, the sealing plug blocks the second steam outlet. The method of controlling the opening and closing of the second steam outlet by using the sealing plug is simple and low-cost.

[0013] A high-temperature steaming oven includes a box body. A main functional cavity and a secondary functional cavity located behind the main functional cavity are provided inside the box body, and the main functional cavity is used as a cooking cavity; the high-temperature steaming oven further includes the steam device described in any of the above embodiments, and the steam device is arranged in the secondary functional cavity; through holes respectively corresponding to the multiple steam outlets are provided on the cavity wall between the main functional cavity and the secondary functional cavity. The high-temperature steaming oven according to the embodiments of the present application can realize two cooking modes of precise steaming and rapid full-cavity steaming to meet the requirements of different cooking methods for different ingredients, while improving the cooking efficiency and ensuring the taste of the food after cooking.

[0014] In some embodiments, the high-temperature steaming oven further includes at least one steaming tray, which is detachably disposed in the cooking cavity to divide the main functional cavity into different cooking areas arranged in sequence from top to bottom. The steaming tray not only serves as a utensil for holding food but also as a component for dividing the cooking cavity. In this way, it is possible to save components, simplify the structure, and facilitate adjusting the formation position of the cooking area.

[0015] In some embodiments, a baffle protrudes upward at the rear side of the steaming tray. Mounting holes are provided on the baffle, and sealing plugs are provided on the mounting holes. When the steaming tray is placed in the main functional cavity, the sealing plugs extend into the second steam outlet to close the second steam outlet. By arranging the sealing plugs on the steaming tray, the risk of loss is avoided.

[0016] A cooking method for a high-temperature steaming oven, wherein the first steam outlet of the steam device of the high-temperature steaming oven is directly communicated with the first cooking area of the cooking cavity of the high-temperature steaming oven; the cooking method includes at least a first cooking mode and a second cooking mode;

[0017] In the first cooking mode, place the food to be steamed in the first cooking area, close the second steam outlet of the steam device, and high-temperature steam is directly sprayed only from the first steam outlet onto the food in the first cooking area to quickly steam the food;

[0018] In the second cooking mode, place the food to be steamed in the same or different cooking areas in the cooking cavity, open the second steam outlet, and high-temperature steam is simultaneously delivered from the first steam outlet and the second steam outlet to the cooking areas communicated therewith and quickly dispersed to fill the entire cooking cavity, so as to steam the food placed in any cooking area. Since this cooking method has two cooking modes, users can select a suitable cooking mode according to different foods, making the food reach the best edible taste and meeting the diverse cooking needs of users.

[0019] Compared with the prior art, the beneficial effects of the embodiments of the present application are as follows: For the steam device and the high-temperature oven of the embodiments of the present application, by providing multiple steam outlets of different types, the steam outlets can be opened or closed according to different foods. When using the first steam outlet to directly spray high-temperature steam onto the food, since the steaming tray divides different cooking areas, the high-temperature steam will not be completely dispersed throughout the entire cooking cavity, so as to achieve the best steaming effect, realize rapid steaming, and save steaming time; when using the first steam outlet and the second steam outlet to simultaneously deliver high-temperature steam to the cooking cavity, since the amount of high-temperature steam delivered is large, it can be evenly dispersed throughout the entire cooking cavity, achieving the effect of steaming a large number of foods simultaneously and improving efficiency. The structure of the present application is simple, the operation is convenient, and it is easy to implement.

[0020] It should be understood that the foregoing general description and the following detailed description are merely exemplary and explanatory and are not intended to limit the present application.

[0042] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted in this application.

[0043] As Figures 1 to 4 shown, an embodiment of this application provides a steam device, which is used on a high-temperature steamer to provide high-temperature steam for the high-temperature steamer to steam the food materials in the high-temperature steamer.

[0044] Continuing to combine Figure 1 、 Figure 3 and Figure 4 , the steam device includes a steam generator or a plurality of steam generators connected in sequence for multi-stage evaporation. The steam generator, which is the one located most upstream in the steam flow direction among the one steam generator and the plurality of sequentially connected steam generators, is the first-stage steam generator 1. The steam generator located most downstream in the steam flow direction among the plurality of steam generators is the last-stage steam generator. Along the steam flow direction, among the plurality of sequentially connected steam generators, the upstream one of two adjacent steam generators is the upper-stage steam generator, and the downstream one is the lower-stage steam generator. The steam outlet of the upper-stage steam generator is connected to the steam inlet of the lower-stage steam generator so that the steam is heated step by step to reach a higher temperature. The inlet of the first-stage steam generator 1 can be connected to a water tank (not shown in the figure) through a water inlet pipe 7. A water pump 8 is provided on the water inlet pipe 7 to send the water in the water tank into the first-stage steam generator 1, and the water is heated into steam in the first-stage steam generator 1. The steam enters the lower-stage steam generator and is continuously heated to form high-temperature steam. The above-mentioned steam generators can respectively adopt steam boilers. Using a boiler as a steam generator not only has a simple structure but also can ensure an adequate steam supply.

[0045] However, when only one first-stage steam generator 1 is adopted, the first-stage steam generator 1 has multiple steam outlets; when multiple sequentially connected steam generators are adopted, the last-stage steam generator thereof has multiple steam outlets, and the multiple steam outlets are respectively communicated with the same or different cooking areas in the cooking cavity 20 of the high-temperature steamer box, so as to send high-temperature steam into the cooking cavity 20 separately or simultaneously. Among them, the multiple steam outlets include at least one first steam outlet 21 directly communicated with the cooking area and at least one second steam outlet 22 capable of switching between closing and opening.

[0046] By providing the first steam outlet 21 and the second steam outlet 22, the steam device of the present application can achieve two cooking modes with completely opposite requirements for steam flow direction and distribution, namely precise steaming and rapid full-cavity steaming. That is, by using the first steam outlet 21 directly communicated with the cooking area, high-temperature steam is directly and concentratedly sprayed onto the ingredients for precise steaming, achieving the effect of rapid steaming of the ingredients, retaining the nutrients in the food and the original taste and texture of the food, and reducing the waiting time; while at the same time using all the steam outlets, the high-temperature steam quickly and evenly fills the entire cooking cavity 20 and wraps the ingredients, realizing full-cavity steaming and meeting the demand for steaming a large number of foods at the same time.

[0047] In some embodiments, as Figure 2 shown, there is one first steam outlet 21, which is arranged corresponding to the first cooking area 60 at the highest position in the high-temperature box body 10, so that the high-temperature steam is directly sprayed into the first cooking area 60. That is, the first steam outlet 21 is directly communicated with the first cooking area 60. By setting the first steam outlet 21 to be one, the spraying speed of the high-temperature steam is faster, which is more conducive to achieving rapid steaming and enabling the ingredients to retain their original flavor; and based on the principle that steam flows upward, by arranging the first steam outlet 21 in the first cooking area 60 at the highest position, the high-temperature steam can be retained in this area as much as possible and the escape to other cooking areas can be reduced.

[0048] In some embodiments, continuing to combine Figure 2 , there are multiple second steam outlets 22, and the multiple second steam outlets 22 are simultaneously communicated with different cooking areas or the same cooking area in the cooking cavity 20 of the high-temperature steamer box. By providing multiple second steam outlets 22, a large amount of high-temperature steam generated by the steam device can be sprayed into the cooking cavity 20 of the high-temperature steam and quickly spread to fill all cooking areas, avoiding the cooling of the high-temperature steam and achieving the purpose of steaming a large number of foods at the same time.

[0049] It can be understood that the cooking chamber 20 of the high-temperature steamer applied in the steam device according to the embodiments of the present application can be divided into multiple different cooking areas as needed, but the multiple cooking areas are not completely isolated from each other, and high-temperature steam can diffuse among the multiple cooking areas. The number of cooking areas is not limited and can be determined according to the properties and quantity of the ingredients to be steamed. However, when performing rapid steaming using the first steam outlet 21, it is necessary to divide out the smallest possible first cooking area 60 that is directly connected to the first steam outlet 21, so that the steam will not be completely dispersed throughout the entire cooking chamber 20, and the high-temperature steam can completely wrap the food in the first cooking area 60, so as to achieve the best food steaming effect, thereby improving the steaming efficiency and saving the steaming time. In the embodiments of the present application Figure 2 A total of three cooking areas are shown, and the three cooking areas can be respectively defined as a first cooking area 60, a second cooking area, and a third cooking area from top to bottom.

[0050] The specific number of the second steam outlets 22 is not limited. Multiple second steam outlets 22 can be provided corresponding to the same cooking area, and when the second steam outlets 22 are opened, high-temperature steam is sprayed into the same cooking area, and then the high-temperature steam diffuses from the same cooking area to other cooking areas. Or multiple second steam outlets 22 correspond to different cooking areas, and for the same cooking area, there can be two or more second steam outlets 22 corresponding to it or there may be no second steam outlet 22 corresponding to it. The layout positions of the multiple second steam outlets 22 corresponding to the same cooking area are not limited and can be at the same height or arranged in a staggered manner.

[0051] In Figure 2 In the illustrated embodiment, there is one first steam outlet 21, which is provided corresponding to the first cooking area 60 and is directly connected to the first cooking area 60. The first steam outlet 21 is used to centrally spray high-temperature steam onto the ingredients placed in the first cooking area 60, or cooperate with the second steam outlets 22 to jointly spray high-temperature steam to fill the entire cooking chamber 20 with high-temperature steam. There are two second steam outlets 22, and both of the two second steam outlets 22 correspond to the first cooking area 60 and are used to spray high-temperature steam into the first cooking area 60, and then the high-temperature steam diffuses to the second cooking area and the third cooking area to achieve steaming of the ingredients placed in all cooking areas. In order to enable the high-temperature steam to directly enter the second cooking area and / or the third cooking area when spraying, second steam outlets 22 corresponding to the second cooking area and / or the third cooking area can also be added, or one or both of the second steam outlets 22 corresponding to the first cooking area 60 can be adjusted to correspond to the second cooking area and / or the third cooking area.

[0052] The opening and closing of the second steam outlets 22 can be achieved by any feasible means, and the present application does not make specific limitations thereto.

[0053] Exemplarily, as Figure 1 and Figure 4 shown, a steam valve 5 is provided at the second steam outlet 22, and the opening or closing of the second steam outlet 22 controlled by the steam valve 5 is achieved.

[0054] As Figure 5 and Figure 6 shown, the steam valve 5 includes a valve body 51 and a valve core 52. A valve cavity 513 is provided inside the valve body 51. The valve core 52 is arranged in the valve cavity 513 and can reciprocate along the valve cavity 513 under the action of an external force to close or open the second steam outlet 22. The structure of the steam valve 5 is simple and reasonable, and can achieve the opening or closing of the second steam outlet 22.

[0055] Continuing to combine Figure 5 and Figure 6 , the steam valve 5 further includes a reset member 53, and the reset member 53 acts on the valve core 52. The valve core 52 includes an iron core 521 and a sealing portion 522 provided at one end of the iron core 521. The valve body 51 includes an iron core seat 511 and an electromagnet 512 provided outside the iron core seat 511. The valve cavity 513 is formed inside the iron core seat 511, and a valve port communicating with the valve cavity 513 is provided on the iron core seat 511. The valve cavity 513 can communicate with both the second steam outlet 22 and the cooking cavity 20 of the high-temperature steam oven through the valve port. When the electromagnet 512 is energized, it adsorbs the iron core 521 to drive the sealing portion 522 to move away from the second steam outlet 22 to open the second steam outlet 22, see Figure 5 ; when the electromagnet 512 is de-energized, the iron core 521 drives the sealing portion 522 to move towards the second steam outlet 22 under the action of the reset member 53 to close the second steam outlet 22, see Figure 6 . The steam valve 5 is actually an electromagnetic control valve, and the opening and closing of the second steam outlet 22 can be controlled by energizing and de-energizing the electromagnet 512 to achieve automatic control. Among them, the energizing and de-energizing of the solenoid valve can be controlled by the control system of the high-temperature steam oven. The control system of the high-temperature steam oven judges whether the second steam outlet 22 needs to be opened according to the cooking mode input by the user, and controls whether to energize and de-energize the solenoid valve.

[0056] In some embodiments, the opening and closing of the second steam outlet 22 can also be achieved without passing through the steam valve 5, that is, no steam valve 5 is provided on the second steam outlet 22. Instead, a pluggable sealing plug 6 is provided on the second steam outlet 22 to achieve the switching between the opening and closing of the second steam outlet 22.

[0057] Exemplarily, the cooking cavity 20 of the high-temperature steam box is separated into multiple cooking areas by a steaming tray 70. At least a pair of opposite sliding grooves 50 are provided on the cavity wall of the cooking cavity 20. By placing the steaming tray 70 along the opposite sliding grooves 50, the cooking cavity 20 can be separated into cooking areas. By adjusting the number of pairs of sliding grooves 50, the number of cooking areas that the cooking cavity 20 can be separated into can be adjusted. As Figure 2 and Figure 4 shown, three pairs of opposite sliding grooves 50 are provided on the cavity wall of the cooking cavity 20. Up to three steaming trays 70 can be placed, and up to three cooking areas can be separated in the cooking cavity 20. When only a steaming tray 70 is placed in a pair of opposite sliding grooves 50, two cooking areas are separated. However, when performing rapid steaming using the first steam outlet 21, a steaming tray 70 must be placed in the uppermost pair of sliding grooves 50 to separate a smaller first cooking area 60, which is conducive to the effective utilization of high-temperature steam.

[0058] As Figure 7 shown, a sealing plug 6 is provided on the steaming tray 70 of the high-temperature steam box. When the steaming tray 70 is placed in the cooking cavity 20 of the high-temperature steam box, the sealing plug 6 seals the second steam outlet 22. See Figure 8 and Figure 9 . When the steaming tray 70 is taken out, the silicone plug is separated from the second steam outlet 22, and the second steam outlet 22 is opened. High-temperature steam can be input into the cooking cavity 20 through the second steam outlet 22. The sealing plug 6 can be made of a rubber plug to improve the sealing effect.

[0059] As Figure 2 shown, when multiple second steam outlets 22 are all arranged to face the first cooking area 60, only one steaming tray 70 needs to be provided with sealing plugs 6 having the same number as the second steam outlets 22. And when rapid steaming that requires precise steaming is needed, only this one steaming tray 70 needs to be placed in the cooking cavity 20 to separate the first cooking area 60. When this steaming tray 70 is placed in the cooking cavity 20, the sealing plugs 6 thereon simultaneously seal all the second steam outlets 22, and only the first steam outlet 21 is communicated with the first cooking area 60. In this way, not only can the structure be simplified and the operation convenience be improved, but also the loss of the sealing plugs 6 can be avoided.

[0060] As Figures 10 to 14As shown in the figure, an embodiment of the present application also provides a high-temperature steam oven, which includes a box body 10 and a door body 40 provided on the box body 10. The box body 10 has a main function cavity and a secondary function cavity 30 located at the rear of the main function cavity, and the main function cavity serves as a cooking cavity 20. The high-temperature steam oven further includes the steam device of any of the above embodiments, and the steam device is provided in the secondary function cavity 30. Through holes corresponding to a plurality of steam outlets one by one are provided on the cavity wall between the main function cavity and the secondary function cavity 30. In the high-temperature steam oven according to the embodiment of the present application, since it includes the steam device of the above embodiment, two cooking modes, namely, fast steaming with precise steaming and rapid full-cavity steaming, can be realized to meet the requirements of different cooking methods for different ingredients, and while improving the cooking efficiency, the taste of the food after cooking is ensured.

[0061] As Figure 1 , Figure 3 , Figure 13 and Figure 14 As shown in the figure, in the embodiment of the present application, the steam device includes two connected steam generators as an example for illustration. The two steam generators are respectively a first-stage steam generator 1 and a second-stage steam generator 2. The first-stage steam generator 1 is located at the bottom of the secondary function cavity 30, and the second-stage steam generator 2 is located above the first-stage steam generator 1. Such a setting facilitates the steam to enter the second-stage steam generator 2 from the first-stage steam generator 1 and then smoothly enter the cooking cavity 20. Among them, Figure 3 , Figure 13 and Figure 14 The arrow directions in the figure respectively represent the flow directions of the steam.

[0062] As Figure 13 and Figure 14 As shown in the figure, the high-temperature steam oven further includes at least one steaming tray 70, and the steaming tray 70 is detachably provided in the cooking cavity 20 to divide the main function cavity into different cooking areas arranged in sequence from top to bottom. In this embodiment, three steaming trays 70 are shown. When the three steaming trays 70 are all provided in the main function cavity (cooking cavity 20), the main function cavity is divided into a first cooking area 60, a second cooking area, and a third cooking area in sequence from top to bottom.

[0063] As Figure 11As shown in the figure, three chutes 50 are respectively provided on the opposite left and right cavity walls of the main functional cavity from top to bottom, and three through holes are respectively provided on the rear cavity wall of the main functional cavity. One through hole in the middle is communicated with the first steam outlet 21, and the two through holes on both sides are respectively communicated with the two second steam outlets 22 in a one-to-one correspondence. The heights of the three through holes are all higher than the height of the uppermost chute 50, and the height difference between the middle through hole and the uppermost chute 50 is minimized. When the steaming tray 70 is placed along the uppermost chute 50, a first cooking area 60 with a relatively small space is formed in the area above the steaming tray 70, and the middle through hole is as close as possible to the steaming tray 70. In this way, the high-temperature steam ejected from the middle through hole (equivalent to the first steam outlet 21) can more easily directly act on the ingredients placed on the steaming tray 70, improving the speed of rapid steaming.

[0064] It can be understood that although different cooking areas can be separated by selectively placing the steaming tray 70 on the chutes 50 at different heights or simultaneously placing the steaming tray 70 on multiple chutes 50 respectively, when performing rapid steaming, the steaming tray 70 needs to be placed on the uppermost chute 50 to reduce the space of the first cooking area 60 and make the ingredients on the steaming tray 70 closer to the middle through hole.

[0065] In some embodiments, as Figure 7 shown, a baffle 80 protrudes upward from the rear side of the steaming tray 70. An installation hole (the installation hole is not shown because it is blocked by the sealing plug 6) is provided on the baffle 80, and a sealing plug 6 is provided on the installation hole. When the steaming tray 70 is placed in the main functional cavity, the sealing plug 6 extends into the second steam outlet 22 to close the second steam outlet 22.

[0066] In order to adapt to Figure 2 the two second steam outlets 22 shown in the figure and avoid the first steam outlet 21 located between the two second steam outlets 22, continuing to combine Figure 7 , the baffle 80 on the steaming tray 70 is two spaced-apart pieces, and an avoidance area for avoiding the first steam outlet 21 is formed between the two baffle 80s. A sealing plug 6 is respectively provided on the two baffle 80s. When the steaming tray 70 is placed on the uppermost chute 50, the sealing plugs 6 on the two baffle 80s simultaneously block the two through holes communicated with the second steam outlets 22.

[0067] The embodiment of the present application further provides a cooking method for a high-temperature steam oven.
