[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] The cooking device 100 according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0043] like Figure 1 , Figure 2 As shown, according to the cooking device 100 of the embodiment of the present invention, the cooking device 100 includes: a base 10, a flow guide 20 and a tray 30.

[0044] The base 10 has a cavity 11 therein and includes a heating element 12 .

[0045] The guide member 20 is detachably disposed in the cavity 11 , and the guide member 20 and the base 10 cooperate to define a steam generating chamber 21 . The heating member 12 is correspondingly disposed in the steam generating chamber 21 to heat the steam generating chamber 21 . The steam generating chamber 21 has a first steam outlet 211 .

[0046] There is water in the steam generating chamber 21 , and the heating element 12 is disposed corresponding to the steam generating chamber 21 , so that the heating element 12 can heat the water in the steam generating chamber 21 accordingly, thereby generating steam.

[0047] It can be understood that the steam generating chamber 21 defined by the guide member 20 and the base 10 is smaller in volume than the cavity 11 , and under the same steam generation speed, the space of the steam generating chamber 21 is filled with steam faster than the cavity 11 .

[0048] It should be noted that the guide member 20 is detachably disposed in the cavity 11 . The guide member 20 can be removed from the cavity 11 to expose the cavity 11 , thereby facilitating cleaning of the cavity 11 and avoiding the accumulation of scale.

[0049] The tray 30 is detachably placed above the guide member 20 and a guide channel 31 is provided between the tray 30 and the guide member 20. The tray 30 is provided with a second steam outlet 331. The guide channel 31 is respectively connected to the first steam outlet 211 and the second steam outlet 331 to guide the steam flow.

[0050] The tray 30 is used to place food, and the guide channel 31 between the tray 30 and the guide member 20 guides the steam so that the steam in the steam generating chamber 21 can quickly contact the food.

[0051] In the related art, a water tank is arranged in the steamer, and a heating pipe arranged at the bottom of the steamer directly heats the water in the water tank to generate steam, and the steam freely diffuses to the steamer above the water tank to heat the food. However, it takes a long time for the steam to fill the entire water tank and then contact the food by relying solely on free diffusion, resulting in a slow cooking speed of the food. The present application provides a steam generating chamber 21 to reduce the space where the steam is located, shorten the time required for the steam to contact the food, and thus improve the cooking speed.

[0052] According to the cooking device 100 of the embodiment of the utility model, by providing a guide member 20, a smaller steam generating chamber 21 is utilized to allow steam to quickly contact food materials, thereby shortening the time required for steam-based food materials and improving the cooking speed. At the same time, the guide member 20 and the tray 30 are detachably arranged so that the cavity 11 can be exposed, thereby facilitating the cleaning of the cavity 11 and avoiding the accumulation of scale.

[0053] Specifically, the cooking device 100 is a steamer, a steam box, etc.

[0054] In some embodiments, the tray 30 is provided with a steam nozzle 33 and a placement piece 60 for holding food, and the upper end of the steam nozzle 33 is provided with a second steam outlet 331, which is higher than the object placement surface of the placement piece 60. By providing the second steam outlet 331, the second steam outlet 331 is higher than the object placement surface, so that the steam sprayed from the second steam outlet 331 can be directly sprayed onto the food, directly heating the food, further improving the cooking rate of the food and shortening the time required for heating the food.

[0055] In the related art, the nozzle in the steamer is generally arranged below the steam rack, and the steam ejected from the nozzle diffuses freely, and the steam diffuses upward to contact the food, but the free diffusion of steam takes time, especially in a large space. The present application sets the second steam outlet 331 higher than the object placement surface, so that the steam ejected from the second steam outlet 331 can directly contact the food, reducing the free diffusion time and speeding up the food heating speed, thereby improving the cooking efficiency.

[0056] In some specific embodiments, the steam nozzle 33 is detachably disposed on the tray 30 , and the steam nozzle 33 of different sizes, heights and spraying directions can be replaced as needed to adapt to various usage environments.

[0057] In some embodiments, the steam nozzle 33 is located at the outer periphery of the tray 30. By arranging the steam nozzle 33 at the outer periphery of the tray 30, it is convenient to heat the food in the middle of the tray 30.

[0058] Specifically, the steam nozzle 33 is located at the outer peripheral edge of the tray 30, and the steam nozzle 33 surrounds the object placement surface. The steam nozzle 33 can spray steam to the food in all directions, so that the food is heated more evenly.

[0059] like Figure 1 , Figure 2 As shown, more specifically, there are two steam nozzles 33, which are respectively arranged on opposite sides of the tray 30, and the two corresponding second steam outlets 331 on the two steam nozzles 33 generate convection, further improving the heating effect.

[0060] In some other specific embodiments, there are four steam nozzles 33, which are respectively arranged on four edges of the tray 30 to fully spray steam. Of course, the steam nozzles 33 can also be other numbers, such as three, five, etc.

[0061] In some embodiments, the central axis of the second steam outlet 331 extends obliquely upward toward the center of the tray 30. By setting the central axis of the second steam outlet 331 to extend obliquely upward toward the center of the tray 30, the steam ejected from the second steam outlet 331 is inclined upward, which facilitates the steam to contact the food and facilitates the steam to diffuse and contact the food more evenly.

[0062] In other embodiments, the central axis of the second steam outlet 331 extends toward the center of the tray 30 , that is, the second steam outlet 331 is parallel to the bottom surface of the tray 30 , and the second steam outlet 331 sprays steam horizontally.

[0063] In other embodiments, the central axis of the second steam outlet 331 extends downwardly and obliquely toward the center of the tray 30. By setting the central axis of the second steam outlet 331 to extend downwardly and obliquely toward the center of the tray 30, the steam ejected from the second steam outlet 331 can directly contact the lower part of the food, thereby improving the cooking speed.

[0064] In some embodiments, the placement piece 60 is spaced apart from the inner bottom wall of the tray 30. By setting the placement piece 60 and the inner bottom wall of the tray 30 spaced apart, that is, the placement piece 60 and the tray 30 are independent of each other, so that it is convenient for users to install and disassemble, and the space between the spaced placement piece 60 and the tray 30 facilitates the flow of steam, thereby improving the cooking effect.

[0065] The inner bottom wall of the tray 30 is spaced apart from the placement member 60 , so that the tray 30 can play a role in catching juice and receive liquids such as oil and water.

[0066] For example, the placement member 60 is configured as a first steaming plate, the top surface of the first steaming plate is configured as an object placement surface, and the first steaming plate is used to place food. By arranging the first steaming plate to place food, the contact area between food and steam is increased, and the cooking effect is improved.

[0067] Specifically, a plurality of through holes are provided on the first steaming plate, which increases the base area of ​​food and steam, thereby improving the cooking effect.

[0068] like Figure 1 , Figure 5 As shown, in some embodiments, the cooking device 100 further includes a second steaming tray 70, which is located above the first steaming tray, and the steam nozzle 33 is located below the second steaming tray 70. By providing the second steaming tray 70, the second steaming tray 70 is located above the object placement surface, and the steam nozzle 33 is located below the second steaming tray 70, and the steam sprayed from the second steam outlet 331 on the steam nozzle 33 is freely diffused to the position of the second steaming tray 70.

[0069] That is to say, the first steaming plate and the second steaming plate 70 are suitable for different ingredients respectively. Ingredients that are more difficult to cook are placed on the first steaming plate, and ingredients that only need to be heated for a shorter time or need to retain their own flavor and color are placed on the second steaming plate 70, so that ingredients with different flavors can be cooked at the same time.

[0070] In some embodiments, the second steaming tray 70 is multiple and spaced apart in the vertical direction. By providing multiple second steaming trays 70, the multi-layer second steaming trays 70 can hold more food materials and increase the cooking capacity.

[0071] In some embodiments, the middle area of ​​the tray 30 is formed as a closed plate body, the outer bottom wall of the middle area of ​​the tray 30 defines the side wall of the guide channel 31, and the second steam outlet 331 is located at the outer periphery of the tray 30. By setting the middle area of ​​the tray 30 as a closed plate body, the closed plate body defines the side wall of the guide channel 31, so that the route of the steam is clearer and simpler, and the energy utilization rate is improved.

[0072] Among them, the direction toward the cooking space 41 is the inside, and the direction away from the cooking space 41 is the outside. The outer bottom wall of the middle area limits the side wall of the guide channel 31, that is, the closed plate body is in contact with the wall surface of the cooking space away from the steam. It should be noted that the second steam outlet 331 is located at the outer peripheral edge of the tray 31, and the middle area contacts the steam and conducts heat to compensate for the temperature of the middle area and avoid a lower temperature in the middle area.

[0073] In some embodiments, the total area of ​​the first steam outlets 211 is greater than the total area of ​​the second steam outlets 331. By setting the total area of ​​the first steam outlets 211 to be greater than the total area of ​​the second steam outlets 331, the speed of the second steam outlets 331 spraying steam is increased, thereby improving the cooking effect.

[0074] It can be understood that the total area of ​​the first steam outlets 211 is greater than the total area of ​​the second steam outlets 331 , that is, more steam is ejected from the second steam outlets 331 , increasing the ejection speed of the steam under the action of pressure.

[0075] In some specific embodiments, a device space is provided in the base 10 , the heating element 12 is provided in the device space, and the bottom surface portion of the cavity 11 is constructed as a heat conducting plate, which is connected to the heating element 12 to heat the steam generating chamber 21 .

[0076] like Figure 1 , Figure 2 As shown, in some embodiments, the guide member 20 cooperates with the base 10 to separate the cavity 11 into a first water cavity 111 and a steam generating cavity 21, the volume of the first water cavity 111 is greater than the volume of the steam generating cavity 21, and the first water cavity 111 is connected to the steam generating cavity 21. By separating the cavity 11 into the first water cavity 111 and the steam generating cavity 21, the volume of the steam generating cavity 21 is further reduced.

[0077] The first water cavity 111 has water, and the first water cavity 111 is used to store water to increase the water storage capacity of the cooking device 100. It should be noted that the first water cavity 111 is connected to the steam generating cavity 21, and the first water cavity 111 supplies water to the steam generating cavity 21, so that steam is continuously generated in the steam generating cavity 21.

[0078] like Figure 1 , Figure 2 As shown, in some embodiments, the first water cavity 111 is arranged around the steam generating cavity 21. By arranging the first water cavity 111 around the steam generating cavity 21, the water in the first water cavity 111 can replenish the steam generating cavity 21 in time, so that the heat generated by the heating element 12 can be diffused to the surroundings more evenly.

[0079] like Figure 1 , Figure 2 As shown, in some embodiments, the guide member 20 includes: a main body portion 22 and an annular extension portion 23 .

[0080] The main body 22 is detachably placed on the base 10 .

[0081] The extension part 23 is provided on the main body 22. The extension part 23 is a hollow structure with an open bottom. The extension part 23 extends downward and is supported on the bottom wall of the cavity 11 to define the steam generation cavity 21. The outer peripheral wall of the extension part 23, the main body 22 and the peripheral wall of the cavity 11 define the first water cavity 111. By providing the main body 22 and the extension part 23, the first water cavity 111 and the steam generation cavity 21 are separated, and the structure is simple and durable.

[0082] It should be noted that the inside and outside here are based on the central axis of the cooking device 100, the direction toward the central axis is the inside, and the direction away from the central axis is the outside.

[0083] The extension part 23 is a hollow structure with an open bottom, and the extension part 23 extending downward is supported on the bottom wall of the cavity 11. The extension part 23 of the hollow structure is buckled on the bottom wall of the cavity 11 to define the steam generating cavity 21. The outer peripheral wall of the extension part 23, the main body 22 and the peripheral wall of the cavity 11 define the first water cavity 111, and the first water cavity 111 is separated from the steam generating cavity 21 by the guide member 20.

[0084] like Figure 1 , Figure 2 As shown, in some embodiments, the extension portion 23 includes a first enclosure 231 and a first inner plate 232. The first enclosure 231 is disposed around the first inner plate 232. The first inner plate 232 is defined by a portion of the main body 22 that is recessed downward. The first inner plate 232 is defined by the main body 22, and the structure of the main body 22 is fully utilized to construct the first inner plate 232 in a relatively simple manner.

[0085] like Figure 1 , Figure 2As shown, specifically, the outer peripheral wall of the first enclosing plate 231, the main body 22 and the peripheral wall of the cavity 11 define the first water cavity 111, and the inner peripheral wall of the first enclosing plate 231, the outer peripheral wall of the first inner plate 232 and the bottom wall of the cavity 11 define the steam generating cavity 21. The structure of the first inner plate 232 further reduces the size of the steam generating cavity 21, thereby further improving the cooking speed.

[0086] In some specific embodiments, the first inner plate 232 is provided with a vent hole 2321 , and the vent hole 2321 is connected to the steam generating chamber 21 , so that the water in the first water chamber 111 can be replenished into the steam generating chamber 21 .

[0087] In some embodiments, a connecting hole is provided at the lower portion of the extension portion 23, and the connecting hole connects the first water cavity 111 and the steam generating cavity 21. By providing the connecting hole to connect the first water cavity 111 and the steam generating cavity 21, the first water cavity 111 can replenish water to the steam generating cavity 21 to increase the amount of steam.

[0088] It can be understood that the connecting hole is small in size, the water in the steam generating chamber 21 is heated and consumed, the water pressure on both sides of the steam generating chamber 21 and the first water chamber 111 is different, the water level in the first water chamber 111 is higher than the water level in the steam generating chamber 21, and the water in the first water chamber 111 is automatically replenished to the steam generating chamber 21.

[0089] like Figure 1 , Figure 2 As shown, specifically, the extension portion 23 includes a first enclosure plate 231 and a first inner plate 232 . The first enclosure plate 231 is arranged around the first inner plate 232 . The first inner plate 232 is defined by a downward recess of a portion of the main body portion 22 . The connecting hole is arranged at the lower portion of the first enclosure plate 231 .

[0090] like Figure 1 , Figure 2 As shown, in some embodiments, the lower end of the extension portion 23 is covered with the heating element 12 so that the heating element 12 is located in the steam generating chamber 21. By arranging the lower end of the extension portion 23 to cover the heating element 12, the heating element 12 is located in the steam generating chamber 21, and the heating element 12 fully heats the water in the steam generating chamber 21, and the guide member 20 can confine the steam in the steam generating chamber 21, thereby limiting the flow of the steam.

[0091] Specifically, the extension portion 23 includes a first enclosure 231 and a first inner plate 232. The first enclosure 231 is arranged around the first inner plate 232. The first inner plate 232 is defined by a portion of the main body 22 that is recessed downward. The connecting hole is provided at the lower portion of the first enclosure 231. The lower end of the first enclosure 231 is covered with the heating element 12 so that the heating element 12 is located in the steam generating chamber 21. The first inner plate 232 further reduces the size of the steam generating chamber 21 and improves the cooking speed.

[0092] like Figure 1 , Figure 2 As shown, in some embodiments, the inner bottom wall of the cavity 11 is provided with an annular groove 112 arranged around the heating element 12, and the lower end of the extension portion 23 is located in the annular groove 112. By extending the lower end of the extension portion 23 into the annular groove 112, it is convenient to position the guide member 20, and at the same time, the steam generating chamber 21 and the first water chamber 111 are further isolated.

[0093] like Figure 1 , Figure 2 As shown, specifically, the extension portion 23 includes a first enclosure plate 231 and a first inner plate 232 . The first enclosure plate 231 is arranged around the first inner plate 232 . The first inner plate 232 is defined by a downward recess of a portion of the main body portion 22 . The lower end of the first enclosure plate 231 is located in the annular groove 112 .

[0094] In some embodiments, the top of the main body 22 is provided with a hooking groove opening downward, and the top of the peripheral wall of the base 10 extends into the hooking groove. By providing the hooking groove to position the flow guide 20, the top of the peripheral wall of the base 10 extends into the hooking groove to stabilize the flow guide 20, which is convenient and practical.

[0095] like Figure 1 As shown, in some embodiments, the cross-sectional area of ​​at least a portion of the steam generating chamber 21 gradually decreases in the upward direction. By setting the cross-sectional area of ​​at least a portion of the steam generating chamber 21 to gradually decrease in the upward direction, the steam generating chamber 21 has a shrinking effect.

[0096] Specifically, the cross-sectional area of ​​the steam generating chamber 21 gradually decreases in the upward direction, and the steam generating chamber 21 exerts a contraction effect to collect more steam inside.

[0097] In some embodiments, the tray 30 is supported on the guide member 20. By arranging that the tray 30 is supported on the guide member 20, it is convenient to remove the tray 30 and the guide member 20 from the base 10 together.

[0098] In other embodiments, the tray 30 is supported on the base 10, and the tray 30 and the guide member 20 are independent of each other, so that they can work separately.

[0099] like Figure 1 As shown, in some embodiments, the cooking device 100 further includes a cover 40, which is covered on the base 10 to define a cooking space 41, and the tray 30 is located in the cooking space 41. The cover 40 and the base 10 are provided to jointly define the cooking space 41, and the steam is confined in the cooking space 41, so that the food can be fully contacted with the steam, thereby improving the cooking effect.

[0100] The tray 30 is located in the cooking space 41 , and the object placement surface on the placement piece 60 is also located in the cooking space 41 .

[0101] In some embodiments, the second steam outlet 331 is located at the lower part of the cooking space 41. By arranging the second steam outlet 331 at the lower part of the cooking space 41, the steam sprayed from the second steam outlet 331 is convenient to diffuse naturally and fill the cooking space 41, thereby improving efficiency.

[0102] like Figure 3 , Figure 4 As shown, in some embodiments, the tray 30 is provided with an exhaust channel 34, and the exhaust channel 34 is spaced apart from the second steam outlet 331. The cooking device 100 further includes a steam valve 50, which is provided in the exhaust channel 34. The steam valve 50 is configured to normally close the exhaust channel 34 and to open the exhaust channel 34 when the steam pressure in the guide channel reaches a set condition. Through the cooperation between the exhaust channel 34 and the steam valve 50, the pressure in the exhaust channel 34 is released when the air pressure is too high, thereby improving safety.

[0103] The steam valve 50 is configured to normally close the exhaust passage 34 , that is, the exhaust passage 34 is closed before the steam pressure in the flow guide passage reaches a set condition.

[0104] like Figure 3 , Figure 4 As shown, in some embodiments, the steam valve 50 includes: a moving part 51 , a blocking part 52 and an elastic part 53 .

[0105] The moving member 51 is movably disposed in the exhaust passage 34 .

[0106] The blocking member 52 is disposed at one end of the moving member 51 to open or block the exhaust passage 34 .

[0107] The elastic member 53 is connected to the moving member 51 and the tray 30 respectively, and the elastic member 53 applies a downward force to the moving member 51 so that the moving member 51 has a movement tendency to drive the blocking member 52 to move to block the exhaust passage 34. By setting the elastic member 53 to act on the moving member 51, the blocking member 52 set at one end of the moving member 51 has the inertia to block the exhaust passage 34, and the structure is simple, convenient, and highly stable.

[0108] Specifically, the elastic member 53 is configured as a spring, and the blocking member 52 is configured as a sealing ring. The sealing ring has a certain elastic deformation capability. Under the elastic force of the spring, the sealing ring is tightly attached to the tray 30 to block the exhaust passage 34 .

[0109] In some specific embodiments, the steam nozzle 33 is located at the outer periphery of the tray 30, and the exhaust channel 34 is located in the middle of the tray 30. By arranging the exhaust channel 34 in the middle of the tray 30, steam is discharged from the exhaust channel 34 to contact the food, thereby compensating for the temperature of the cold zone in the middle caused by the steam nozzle 33 being located at the outer periphery, thereby making the temperature in the cooking space 41 more uniform.

[0110] like Figure 5 As shown, in some specific embodiments, the cover body 40 includes: a support member 42 and a top cover 43 .

[0111] The support member 42 is disposed on the base 10 .

[0112] The top cover 43 is disposed on the support member 42 , and the top cover 43 , the support member 42 and the base 10 together define a cooking space 41 .

[0113] The support member 42 is provided with a second steaming plate 70 , the second steaming plate 70 is located above the first steaming plate, and the steam nozzle 33 is located below the second steaming plate 70 .

[0114] Specifically, there are a plurality of support members 42 , which are stacked up and down, and the second steaming tray 70 is correspondingly disposed on the support members 42 .

[0115] It should be noted that in the present application, in order to make the temperature inside the cooking cavity uniform, the number of steam nozzles, nozzle size, nozzle shape, nozzle height and spray direction can be adjusted according to the capacity and shape of the cooking cavity, steam flow rate and other influencing factors, that is, the number of steam nozzles can be one or more, and they are respectively set at different positions; the size and shape of the steam outlet of the steam nozzle can be adjusted according to the power of the heating element 12 and the flow rate of steam generated to prevent the steam pressure in the pipeline from being too high or too low; the direction of the nozzle opening can also be set to be obliquely upward, obliquely downward or parallel to the bottom surface, so that steam can be sprayed into various parts of cavities of different shapes to avoid local cold areas that affect the cooking of ingredients.

[0116] Combine the following Figures 1 to 5 , a cooking device 100 according to an embodiment of the present utility model is described in detail.

[0117] The cooking device 100 is a steamer, and includes: a base 10, a flow guide 20, a tray 30, a cover 40, a steam valve 50, and a first steaming plate.

[0118] The heating element is assembled in the base 10 as a heating component; the bottom of the guide member 20 contacts the circumference of the heating element, and the top of the guide member 20 forms a seal with the inner wall of the base 10; the tray 30 is assembled on the base 10 and forms a seal with the base 10, that is, the guide member 20, the tray 30 and the base 10 are sealed separately, and together form a closed guide space. After the steam is generated at the position of the heating element, it can move along the closed guide space, flow through the first steam outlet 211 on the guide member 20, and be ejected from the second steam outlet 331 on the side of the tray 30; the cover body 40 is placed on the tray 30 to form a cooking space 41, and the food is placed in the cooking space 41, and is heated by the injected steam to complete the cooking.

[0119] An exhaust channel 34 is provided in the middle of the tray 30, and a steam valve 50 is provided in the exhaust channel 34. The steam valve 50 includes: a moving part 51, a blocking part 52 and an elastic part 53. Among them, the blocking part 52 is a sealing ring, and the elastic part 53 is a spring, and the spring is initially in a compressed state. Under normal working conditions, the sealing ring seals the exhaust channel 34 in the middle of the tray 30 under the action of the spring. When the air pressure in the closed guide space is too high, the steam overcomes the spring force to lift the moving part 51, and the steam can be discharged from the exhaust channel 34 in the middle of the tray 30. On the one hand, this structure can play a protective role when the air pressure inside the guide space is too high, thereby improving safety; on the other hand, since the steam is ejected from the side in this scheme, and the steam will spontaneously move upward, a cold zone will be formed in the middle. The temperature of this area will be low due to the lack of direct steam injection. At this time, the high-temperature steam is discharged from the middle of the tray 30 through the aforementioned pressure relief structure, which can compensate for the temperature of the cold zone in the middle, making the temperature inside the container more uniform.

[0120] In this solution, by setting up a closed guide space, steam can be ejected from the side of the cooking space 41 at a certain initial velocity and injection angle, directly contacting the food, and at the same time accelerating the convective heat transfer rate, so that the temperature of the food rises faster. Compared with the steamer structure of the related art, this solution can increase the cooking speed of the steamer, improve the taste of the food, and reduce the consumption of electricity and water. Compared with the steamer using a steam generator, the heating structure of this solution is open, and it is easy to clean the scale, and there will be no risk of scale clogging common in the steam generator solution.
