Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, in particular to an electric steamer. BACKGROUND

[0002] Steam cooking can make food retain nutrients, and is one of the common cooking methods in daily life. An electric steamer is a very common cooking appliance that utilizes steam cooking. A traditional electric steamer needs to heat the whole pot of water to generate steam, so as to cook food. The pre-heating of the whole pot of water prolongs the cooking time, and the overall cooking time is also lengthened, resulting in a decline in the taste of the cooked food.

[0003] The way to solve this problem in the industry is to increase the power, which has a small effect on the steam generation speed and greatly increases the cost of the electric appliance. There is also a way of controlling water through mechanical buoyancy to achieve a small water level effect to improve the steam generation speed, but this technology is limited by the function and cannot be realized on the cooking platform. Of course, there is also a way of pumping water into the steam generator through a water pump to achieve rapid steam generation. This scheme is also unable to be realized due to the limitation of the cooking function and the high cost of the control electric device. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide an electric steamer that is simple in structure and can quickly generate steam.

[0005] An electric steamer, comprising a base, a cooking main body, a steaming tray and a heating piece, wherein the base is provided with a containing cavity, the cooking main body is provided with a cooking cavity, the cooking main body is arranged above the base, the steaming tray is arranged between the base and the cooking main body, and the heating piece is arranged below the containing cavity, characterized in that a bottom wall of the steaming tray is provided with a first partition plate extending downward and in a ring shape, a first steam port located in a region surrounded by the first partition plate, and a second steam port located outside the region surrounded by the first partition plate, when the steaming tray is placed on the base, the first partition plate divides the containing cavity into a steam generation cavity located inside the first partition plate and a water tank located outside the first partition plate, the steam generation cavity and the water tank are in communication at a lower end of the first partition plate, the heating piece is located in a projection region surrounded by the first partition plate, and the first steam port is a small hole, so that when the heating piece works, a certain air pressure is maintained in the steam generation cavity, and a height difference is formed between the water surfaces inside and outside the first partition plate.

[0006] The electric steamer provided in the application generates steam by heating water in the steam generating cavity through the heating element, and the steam enters the cooking cavity through the first steam port for cooking. The first steam port is provided as a small hole in the application. As long as the steam discharge rate is lower than the steam generation rate, the steam generating cavity can maintain a certain air pressure, so that the steam in the steam generating cavity will force the water to flow to the water tank, causing the water level in the steam generating cavity to drop and the water level in the water tank to rise, forming a height difference. Subsequently, only a small amount of water in the steam generating cavity needs to be heated to continuously generate steam. As the water in the steam generating cavity is consumed and the water level drops, the water in the water tank can be continuously replenished into the steam generating cavity, thereby continuously generating steam until the water level in the water tank drops to a certain extent, the water level difference between the water tank and the steam generating cavity is less than the air pressure in the steam generating cavity, and the steam generated in the steam generating cavity enters the cooking cavity through the first steam port and the second steam port at the same time, improving the uniformity of steam heating. It can be seen that the electric steamer provided in the application has a very simple structure and can quickly generate steam. In addition, the first partition plate separates the cavity into a steam generating cavity and a water tank. After the steaming tray is removed, the cavity of the base is a complete chamber without a partition plate structure and a valve structure, which is easy to clean.

[0007] In one of the embodiments, the first steam port is provided as a capillary hole.

[0008] In this way, the steam can be discharged at a slower speed, thereby facilitating the control of the steam generating cavity at a low water level, and thereby quickly generating steam.

[0009] In one of the embodiments, the first steam port is arranged at the central region of the bottom wall of the steaming tray.

[0010] In this way, it is beneficial for the steam to smoothly enter the cooking cavity through the first steam port and for the steam to be uniformly distributed in the cooking cavity.

[0011] In one of the embodiments, the first steam port is provided as a plurality of first steam ports, and the plurality of first steam ports are arranged at intervals.

[0012] In this way, the steam can quickly enter the cooking cavity, ensuring that the cooking cavity has sufficient amount of steam to ensure the cooking effect, and avoiding the accumulation of too much steam in the steam generating cavity, which causes the steaming tray to shake due to steam impact.

[0013] In one of the embodiments, the first steam port is arranged in a matrix, or the first steam port is arranged in a ring array.

[0014] In this way, it is beneficial for the steam to be sprayed from the central region of the steaming tray, and the first steam port arranged in this way is easy to process and has an attractive appearance.

[0015] In one of the embodiments, the second steam port is provided in plurality, and the plurality of second steam ports are arranged in a circumferential direction of the first partition plate.

[0016] In this way, when the water tank is in a low water level, steam can be uniformly discharged into the cooking cavity through the second steam port, thereby ensuring that high-efficiency steam discharge can still be achieved when the water tank is in a low water level.

[0017] In one of the embodiments, the second steam port is arranged in one or more circles in a radial direction of the first partition plate.

[0018] In this way, steam that escapes from the lower end of the first partition plate can be quickly discharged into the cooking cavity from the second steam port, thereby enabling the cooking cavity to still maintain a relatively large amount of steam when the water tank is in a low water level.

[0019] In one of the embodiments, the bottom wall of the steaming tray is further provided with a second partition plate that extends downward, the second partition plate is annular and arranged around the first partition plate, and the second steam port is located inside the second partition plate.

[0020] In this way, the second partition plate can block steam flowing toward the sidewall of the cavity, thereby guiding the steam to flow toward the second steam port and reducing heat loss caused by the contact between the steam and water located outside the second partition plate in the water tank. Moreover, when the water tank is in a low water level, the arrangement of the second partition plate is beneficial to quickly heating the small amount of water inside the second partition plate, thereby achieving rapid steam discharge.

[0021] In one of the embodiments, when the steaming tray is placed on the base, none of the lower ends of the first partition plate is in contact with the bottom wall of the cavity.

[0022] In this way, the steam generation cavity and the water tank are in communication, and water in the water tank can be replenished into the steam generation cavity in a timely manner.

[0023] In one of the embodiments, the total flow area of the first steam port is smaller than the total flow area of the second steam port.

[0024] In this way, when the water tank is in a low water level, steam is simultaneously output from the first steam port and the second steam port into the cooking cavity, thereby ensuring that the cooking cavity has a relatively large amount of steam, and high-efficiency cooking can still be achieved in the later cooking stage.

[0038] See Figure 1 and Figure 2The application provides an electric steamer, which comprises a base 10, a cooking main body 20, a steaming tray 30 and a heating piece 60. The base 10 is provided with a containing cavity 101, the cooking main body 20 is provided with a cooking cavity 21, the cooking main body 20 is arranged above the base 10, the steaming tray 30 is arranged between the base 10 and the cooking main body 20, and the heating piece 60 is arranged below the containing cavity 101. A bottom wall of the steaming tray 30 is provided with a first baffle plate 33 extending downward and in a ring shape, a first steam port 31 located in a region surrounded by the first baffle plate 33 and a second steam port 32 located outside the region surrounded by the first baffle plate 33. When the steaming tray 30 is placed on the base 10, the first baffle plate 33 divides the containing cavity 101 into a steam generation cavity 11 located inside the first baffle plate 33 and a water tank 12 located outside the first baffle plate 33, and the steam generation cavity 11 and the water tank 12 are communicated at a lower end of the first baffle plate 33. The heating piece 60 is located in a projection region surrounded by the first baffle plate 33, and the heating piece 60 is used for heating water in the steam generation cavity 11 to generate steam. The first steam port 31 is arranged as a small hole, so that when the heating piece 60 works, a certain air pressure is maintained in the steam generation cavity 11, and a height difference is formed between water surfaces on the inside and outside of the first baffle plate 33. In this way, steam is generated by heating water in the steam generation cavity 11 by the heating piece 60, and the steam enters the cooking cavity 21 through the first steam port 31 to cook. According to the application, the first steam port 31 is arranged as a small hole, so that as long as the steam discharge rate is lower than the steam generation rate, a certain air pressure can be maintained in the steam generation cavity 11, so that the steam in the steam generation cavity 11 presses the water to flow to the water tank 12, the water level in the steam generation cavity 11 is lowered, the water level in the water tank 12 is raised, and a height difference is formed, and subsequently only a small amount of water in the steam generation cavity 11 needs to be heated to continuously generate steam. Subsequently, as the water in the steam generation cavity 11 is consumed and the water level is lowered, the water in the water tank 12 can be continuously supplemented into the steam generation cavity 11, so that steam can be continuously generated. It can be seen that the electric steamer provided by the application has a very simple structure and can quickly generate steam. In addition, according to the application, the containing cavity 101 is divided into the steam generation cavity 11 and the water tank 12 by the first baffle plate 33, after the steaming tray 30 is removed, the containing cavity 101 of the base 10 is a complete cavity and does not have a baffle plate structure and a valve structure inside, so that the base 10 is easy to clean. Furthermore, when the first baffle plate 33 is assembled, after the lower end of the first baffle plate 33 is submerged in water, the air inside the first baffle plate 33 can only be discharged through the first steam port 31, and as the first steam port 31 is a small hole, the air inside the first baffle plate 33 cannot be discharged in time, so that the air presses the water to flow to the outside of the first baffle plate 33, so that the water level in the steam generation cavity 11 inside the first baffle plate 33 is lowered. At this time, the heating piece 60 is turned on, so that only the low water level in the steam generation cavity 11 needs to be heated to generate steam. It can be seen that the structure can realize low water level control when the steaming tray 30 is placed, so that steam can be quickly generated.It can be understood that when the steaming tray 30 is assembled, the inside and outside of the first partition plate 33 will form a water level difference. At this time, if the heating element 60 is not turned on, over time, the air in the steam generation cavity 11 on the inside of the first partition plate 33 will gradually be discharged, so that the water level in the steam generation cavity 11 slowly rises and eventually levels off with the water level in the water tank 12.

[0039] In this embodiment, the cooking main body 20 includes a pot cover 22, and the inside of the pot cover 22 forms a cooking cavity 21. A steaming rack can be arranged in the cooking cavity 21 to support the food being steamed. In addition, in other embodiments, the cooking main body 20 can also include a steaming basket, and the inside of the steaming basket forms the cooking cavity 21, or the steaming basket and the pot cover 22 enclose the cooking cavity 21. The present application does not limit this, as long as the cooking main body 20 is provided with a cooking cavity 21 capable of accommodating food.

[0040] Please refer to Figure 1 and Figure 2 In this embodiment, when the steaming tray 30 is placed on the base 10, the lower end of the first partition plate 33 does not contact the bottom wall of the containing cavity 101, so that the steam generation cavity 11 and the water tank 12 are in communication, and the water in the water tank 12 can be replenished to the steam generation cavity 11 in time. However, it is not limited to this, and in other embodiments, the lower end of the first partition plate 33 can be provided with a communication port, which can penetrate the lower end face of the first partition plate 33 or not. When the steaming tray 30 is assembled on the base 10, the steam generation cavity 11 and the water tank 12 can be in communication through the communication port, so that the water in the water tank 12 can also be replenished to the steam generation cavity 11 in time. Further, a plurality of communication ports can be provided, and the plurality of communication ports are uniformly spaced along the circumference of the first partition plate 33. In this way, it is beneficial to replenish water from the water tank 12 to the steam generation cavity 11.

[0041] Further, the first steam port 31 is provided as a capillary hole. It can be understood that the "capillary hole" refers to a through hole with a small diameter. By providing the first steam port 31 as a capillary hole, the speed of steam discharge can be slower, thereby facilitating the control of the steam generation cavity 11 at a low water level, and thereby enabling rapid steam generation.

[0042] Further, the first steam port 31 is provided in the central region of the bottom wall of the steaming tray 30. In this way, it is beneficial for the steam to smoothly pass through the first steam port 31 into the cooking cavity 21, and it is beneficial for the steam to be evenly distributed in the cooking cavity 21.

[0043] Further, the first steam port 31 is provided as a plurality of first steam ports 31, and the plurality of first steam ports 31 are arranged at intervals. In this way, steam can quickly enter the cooking cavity 21, ensuring that the cooking cavity 21 has sufficient amount of steam to ensure the cooking effect, and avoiding the accumulation of too much steam in the steam generation cavity 11, which can cause the steaming tray 30 to shake due to steam impact.

[0044] Further, the first steam ports 31 are arranged in a matrix, or the first steam ports 31 are arranged in a ring array, thus, the steam is facilitated to be discharged from the central area of the steaming tray 30, and the first steam ports 31 arranged in this way are easy to process and have a beautiful shape.

[0045] In the present application, by arranging the first steam ports 31 with appropriate sizes, the water level in the steam generating cavity 11 can be controlled below the preset water level line A, please refer to Figure 1 It can be understood that "below the preset water level line A" includes "the preset water level line A", that is, the water level in the steam generating cavity 11 can be located at the height position of the preset water level line A, or below the preset water level line A. In an embodiment, the distance between the preset water level line A and the bottom wall of the cavity 101 is H, 10mm≤H≤20mm. In this way, the height position of the preset water level line A is neither too high nor too low, so as to ensure rapid steam generation and reduce the occurrence of dry burning.

[0046] During the working process of the electric steamer, when the water level in the steam generating cavity 11 decreases, the water tank 12 can supplement water into the steam generating cavity 11 in time, so that the steam generating cavity 11 is maintained at the height of the preset water level line A. As the cooking proceeds, the water level in the water tank 12 gradually decreases, so that the water level pressure difference between the water tank 12 and the steam generating cavity 11 gradually decreases. When the water level pressure difference is reduced to a certain extent, the steam in the steam generating cavity 11 will flow into the water tank 12 and then flow into the cooking cavity 21 from the second steam port 32. As can be seen, when the water tank 12 is at a high water level C, as Figure 4 shown, the steam is discharged into the cooking cavity 21 through the first steam port 31; when the water tank 12 is at a low water level C', as Figure 5 shown, the steam can also be discharged into the cooking cavity 21 through the second steam port 32, that is, the steam generated in the steam generating cavity 11 enters the cooking cavity 21 from the first steam port 31 and the second steam port 32 at the same time, so as to realize efficient cooking. It can be understood that since the first steam port 31 is arranged as a small hole, when the water tank 12 is at a low water level C', the steam is discharged from the first steam port 31 and the second steam port 32 at the same time. It can be understood that when the pressure in the steam generating cavity 11 is greater than the pressure in the water tank 12, the steam will also escape from the lower end of the first partition plate 33 and enter the cooking cavity 21 through the second steam port 32.

[0047] Further, the second steam port 32 is arranged as a plurality of second steam ports 32, and the plurality of second steam ports 32 are arranged along the circumference of the first partition plate 33. In this way, when the water tank 12 is at a low water level, the steam can be uniformly discharged into the cooking cavity 21 through the second steam port 32, so as to ensure that efficient steam discharge can still be realized at a low water level.

[0048] Further, the second steam port 32 is arranged in one or more circles along the radial direction of the first partition plate 33. In this way, the steam escaping from the lower end of the first partition plate 33 can be quickly discharged from the second steam port 32 into the cooking cavity 21, so that more steam can be maintained in the cooking cavity 21 when the water tank 12 is at a low water level.

[0049] Further, the total flow area of the first steam port 31 is smaller than the total flow area of the second steam port 32. It can be understood that the "total flow area" refers to the sum of the cross-sectional areas in the direction perpendicular to the flow direction of the steam. In this way, when the water tank 12 is at a low water level, steam is output from the first steam port 31 and the second steam port 32 into the cooking cavity 21 at the same time, which ensures that more steam is maintained in the cooking cavity 21, so that efficient cooking can also be achieved in the later cooking stage.

[0050] Please refer to Figures 3 to 5 Further, the bottom wall of the steaming tray 30 is further provided with a second partition plate 34 extending downward, the second partition plate 34 is annular and arranged around the first partition plate 33, and the second steam port 32 is located on the inner side of the second partition plate 34. In this way, the second partition plate 34 can block the steam flowing to the side wall of the cavity 101, so as to guide the steam to flow to the second steam port 32, thereby reducing the heat loss caused by the contact between the steam and the water located on the outer side of the second partition plate 34 in the water tank 12. Moreover, when the water tank 12 is at a low water level, the arrangement of the second partition plate 34 is beneficial to quickly heat the small amount of water on the inner side of the second partition plate 34, so as to achieve rapid steam generation.

[0051] As shown in Figure 1 and Figure 2 In the present application, the heating element 60 is arranged below the bottom wall of the steam generation cavity 11, so that the heating element 60 only heats the water in the steam generation cavity 11, which is beneficial to quickly generate steam. It can be understood that if steam is only output through the first steam port 31, it may lead to uneven distribution of steam in the cooking cavity 21. Therefore, the amount of steam can be increased by increasing the heating power of the heating element 60, so that steam is output from the first steam port 31 and the second steam port 32 at the same time, as shown in Figure 6 , so as to improve the uniformity of the steam in the cooking cavity 21. In the present embodiment, the heating element 60 is a heating pipe and is annular, which has a very simple structure.

[0052] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present application.

[0053] The above-described embodiments are merely illustrative of several embodiments of the present application, which are described in more detail and in a specific manner, but should not be construed as limiting the scope of the patent application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
