Abstract
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 fully, 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 heats water in the bottom to generate steam to heat food in a cooking cavity. The steam generated in this way has a high saturation degree and a low temperature, and will quickly condense into a water film on the surface of the food after contacting the food, resulting in over-wetting of the food and affecting the taste. Using high-temperature steam can effectively improve the taste of food. In the industry, high-temperature steam is currently generated by heating steam generated by primary heating through secondary heating. In the prior art, the heat source for secondary heating usually passes through water, and the heat generated by the secondary heating heat source is partially absorbed by the water, resulting in a decrease in the heating efficiency of the steam. CONTENT OF THE UTILITY MODEL
[0003] Therefore, it is necessary to provide an electric steamer that can improve the heating efficiency of steam.
[0004] An electric steamer includes a base, a cooking main body, and a cover. The base is provided with a steam generation cavity. The cooking main body is provided with a cooking cavity. The cooking main body is arranged above the base. The cover is arranged on the base. The cover covers the steam generation cavity. The cover is provided with a steam inlet that communicates the steam generation cavity and the cooking cavity. The electric steamer further includes a water tank for supplying water to the steam generation cavity, a first heating member for heating water in the steam generation cavity to generate steam, and a second heating member for heating steam. The water tank and the steam generation cavity are connected through a water control assembly. The water control assembly is used to control the water level in the steam generation cavity to be below a preset water level line. The first heating member is arranged on the bottom wall of the steam generation cavity. The side portion of the steam generation cavity is provided with a mounting step. The second heating member is arranged on the mounting step. The portion of the second heating member located in the steam generation cavity is located above the preset water level line.
[0005] The electric steamer provided in the application can generate steam by heating water in the steam generation cavity through the first heating member. Since the water level in the steam generation cavity can be controlled below the preset water level line by the water control assembly, steam can be generated quickly. The steam is heated by the second heating member during the rising process to form high-temperature steam, and then enters the cooking cavity through the steam inlet to cook food. In this way, high-temperature cooking can be realized. Since the part of the second heating member located above the preset water level line in the steam generation cavity can avoid heating the water in the steam generation cavity, the heat generated by the second heating member is all used to heat the steam, greatly improving the heating efficiency of the steam, and at the same time, the second heating member can avoid scale on the surface, so as to also not affect the heating efficiency of the second heating member.
[0006] In one of the embodiments, the mounting step is higher than the preset water level line, and the second heating member is mounted on the top surface or the side wall of the mounting step.
[0007] In this way, the mounting step provides the second heating member with a mounting position higher than the preset water level line, so that the second heating member will not be in contact with water, thereby avoiding the heat generated by the second heating member being used to heat the water and affecting the heating efficiency of the steam.
[0008] In one of the embodiments, the mounting step is located inside or outside the steam generation cavity.
[0009] In this way, when the mounting step is located inside the steam generation cavity, it is convenient to install the second heating pipe. When the mounting step is located outside the steam generation cavity, the wiring terminal of the second heating pipe is mounted outside the steam generation cavity, and the waterproof design requirement of the wiring terminal is reduced.
[0010] In one of the embodiments, the second heating member includes a heating body arranged in a circumferential direction around the cooking cavity, and the heating body is arranged in at least two circles in a radial direction of the cooking cavity.
[0011] In this way, each circle of the heating body can heat the steam around, so that the contact area between the heating body and the steam is larger, and the heating range is also larger, so that more steam is heated to form high-temperature steam, thereby greatly improving the heating efficiency of the high-temperature steam.
[0012] In one of the embodiments, each circle of the heating body is annular or spiral.
[0013] In this way, the structure of the heating body is very simple and easy to process.
[0014] In one of the embodiments, the distance between the preset water level and the bottom wall of the steam generating cavity is H1, 5mm≤H1≤20mm, the distance between the lowest part of the heating body and the bottom wall of the steam generating cavity is H2, H2≤150mm, 0.1≤H1 / H2≤0.8.
[0015] In this way, the height of the preset water level is neither too high nor too low, so that the steam can be generated quickly, the water is less likely to contact the second heating element, and the dry burning condition is reduced. The distance between the heating body and the preset water level is not too large, so that the steam generated after the water is heated can quickly rise around the heating body to be heated by the heating body, and more steam can pass through the second heating element to be heated to form high-temperature steam, thereby ensuring the heating efficiency of the high-temperature steam.
[0016] In one of the embodiments, the outermost circle of the heating body is in a circular ring shape, the outer diameter of the outermost circle of the heating body is L2, the bottom wall of the steam generating cavity is in a circular shape, the diameter of the bottom wall of the steam generating cavity is L1, 1 / 2L1≤L2≤3L1.
[0017] In this way, the size of L2 is moderate, which ensures sufficient heating range and sufficient amount of high-temperature steam, and reduces heat waste and the requirement for the temperature resistance of the base and the cover.
[0018] In one of the embodiments, the cover includes a cover top wall and a cover side wall, the cover side wall is connected to the circumferential side of the cover top wall and extends downward, the cover side wall is sealingly connected to the side wall of the steam generating cavity, and the steam inlet is arranged on the cover top wall and / or the cover side wall.
[0019] In this way, the cover surrounds the steam, and the second heating element can more efficiently heat the steam, so that the production efficiency of the high-temperature steam is higher.
[0020] In one of the embodiments, the lowest part of the steam inlet is higher than or flush with the highest part of the heating body.
[0021] In this way, the high-temperature steam formed in the part of the cover above the heating body flows out, and can directly enter the cooking cavity, so that the path of the high-temperature steam entering the cooking cavity is short, and heat loss can be reduced.
[0022] In one of the embodiments, the steam inlet is one or more, the flow area of a single steam inlet is S, S≥10mm 2 , the total flow area of the steam inlets is S1, the surface area of the outside of the cover is S2, 0.05≤S1 / S2≤0.8.
[0023] Therefore, the high-temperature steam can be smoothly discharged from each steam inlet, the high-temperature steam in the cover can be smoothly discharged in a large range and uniformly, and the high-temperature steam can reach a required temperature.
[0024] In one of the embodiments, the base is provided with a containing cavity, and an annular partition plate is arranged in the containing cavity, which divides the containing cavity into the water tank and the steam generating cavity.
[0025] Therefore, the electric steamer has a simple structure and is easy to process.
[0026] In one of the embodiments, the base is provided with a containing cavity, and an annular partition plate is arranged in the containing cavity, which divides the containing cavity into the water tank and the steam generating cavity.
[0027] Therefore, the water receiving tray can simultaneously have the functions of the cover and the condensate water receiving. BRIEF DESCRIPTION OF DRAWINGS

[0040] Please refer to Figures 1 to 5 The application provides an electric steamer, which comprises a base 10, a cooking main body 20 and a cover 30. The base 10 is provided with a steam generating cavity 11, and the cooking main body 20 is provided with a cooking cavity 21. The cooking main body 20 is arranged above the base 10. The cover 30 is arranged on the steam generating cavity 11, and the cover 30 is provided with a steam inlet 31. The steam inlet 31 is connected with the steam generating cavity 11 and the cooking cavity 21. The electric steamer further comprises a water tank 40 for supplying water to the steam generating cavity 11, a first heating element 50 for heating water in the steam generating cavity 11 to generate steam, and a second heating element 60 for heating steam. The water tank 40 and the steam generating cavity 11 are connected through a water control assembly 70. The water control assembly 70 is used for controlling the water level in the steam generating cavity 11 to be below a preset water level line A. 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. The first heating element 50 is arranged on the bottom wall of the steam generating cavity 11. The side of the steam generating cavity 11 is provided with a mounting step 13. The second heating element 60 is arranged on the mounting step 13. The part of the second heating element 60 located in the steam generating cavity 11 is located above the preset water level line A. In this way, the first heating element 50 heats the water in the steam generating cavity 11 to generate steam. Since the water control assembly 70 can control the water level in the steam generating cavity 11 to be below the preset water level line A, steam can be generated quickly. The steam is heated by the second heating element 60 during the rising process to form high-temperature steam. Then the steam enters the cooking cavity 21 through the steam inlet 31 to cook food. In this way, high-temperature cooking can be realized. Since the part of the second heating element 60 located in the steam generating cavity 11 is located above the preset water level line A, the second heating element 60 can avoid heating the water in the steam generating cavity 11. The heat generated by the second heating element 60 is all used for heating steam, which greatly improves the heating efficiency of the steam. At the same time, the second heating element 60 can avoid scale on the surface, so as not to affect the heating efficiency of the second heating element 60.
[0041] In this embodiment, the cooking main body 20 comprises a pot cover 22, and a cooking cavity 21 is formed inside the pot cover 22. A steaming rack 23 can be arranged in the cooking cavity 21 to support food to be steamed. In other embodiments, the cooking main body 20 can also comprise a steaming cage, and the cooking cavity 21 can be formed inside the steaming cage, or the cooking cavity 21 can be enclosed by the steaming cage and the pot cover 22. 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.
[0042] Further, referring to Figure 3 and Figure 5 , the mounting step 13 is higher than the preset water level A, and the second heating element 60 is mounted on the top surface or the side wall of the mounting step 13. In this way, the mounting step 13 provides a mounting position for the second heating element 60 that is higher than the preset water level A, so that the second heating element 60 will not be in contact with water, thereby avoiding the heat generated by the second heating element 60 from being used to heat the water, which affects the heating efficiency of the steam.
[0043] Further, the mounting step 13 is arranged inside the steam generation cavity 11, so that the second heating element 60 is convenient to install. However, the mounting step 13 can also be arranged outside the steam generation cavity 11, and correspondingly, the second heating element 60 penetrates into the steam generation cavity 11 from the side wall of the steam generation cavity 11. In this way, the wiring terminal 63 of the second heating element 60 is mounted outside the steam generation cavity 11, and the waterproof design requirement of the wiring terminal 63 is reduced.
[0044] Further, the second heating element 60 comprises a heating main body 61 arranged in a circumferential direction of the cooking cavity 21. The heating main body 61 is arranged in at least two circles in a radial direction of the cooking cavity 21. In this way, the heating main body 61 in each circle can heat the steam around it, so that the contact area between the heating main body 61 and the steam is larger, and the heating range is also larger, so that more steam is heated to form high-temperature steam, thereby greatly improving the heating efficiency of the high-temperature steam.
[0045] Further, each circle of the heating main body 61 is annular or spiral. In this way, the structure of the heating main body 61 is very simple and easy to process. The spiral heating main body 61 is longer in length and has a larger contact area with the steam, thereby being conducive to forming more high-temperature steam. The annular heating main body 61 has a simpler structure and lower cost. In this embodiment, each circle of the heating main body 61 is annular.
[0046] The second heating element 60 further comprises a wiring terminal 63 and a connecting section 62. The wiring terminal 63 is mounted on the mounting step 13, and the connecting section 62 connects the heating main body 61 and the wiring terminal 63. The wiring terminal 63 can be detachably arranged on the mounting step 13 or non-detachably mounted on the mounting step, and the present application does not limit this.
[0047] Referring to Figure 3In an embodiment, the distance between the preset water level A and the bottom wall of the steam generating cavity 11 is H1, and 5mm≤H1≤20mm. In this way, the height of the preset water level A is neither too high nor too low, so that the steam can be generated quickly, and the water is less likely to contact the second heating member 60, and the dry burning condition is reduced. Specifically, H1 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, or any other value within the range of 5mm to 20mm.
[0048] The distance between the lowest part of the heating body 61 and the bottom wall of the steam generating cavity 11 is H2, and H2≤150mm. In this way, the distance between the heating body 61 and the preset water level is not too large, so that the steam generated after the water is heated can quickly rise around the heating body 61 to be heated by the heating body 61, thereby quickly forming high-temperature steam to meet the demand of high-temperature cooking.
[0049] Further, 0.1≤H1 / H2≤0.8, so that more steam can be heated by the second heating member 60 to form high-temperature steam, thereby ensuring the heating efficiency of the high-temperature steam.
[0050] In an embodiment, the outermost circle of the heating body 61 is in a circular ring shape, the outer diameter of the outermost circle of the heating body 61 is L2, the bottom wall of the steam generating cavity 11 is in a circular shape, the diameter of the bottom wall of the steam generating cavity 11 is L1, and 1 / 2L1≤L2≤3L1. If L2 is too small, the heating range is small, and the generated high-temperature steam is also small, which is difficult to meet the demand of high-temperature steam cooking. If L2 is too large, the steam generated by the steam generating cavity 11 is insufficient, which causes waste of heat, and the requirement for the temperature resistance of the base 10 and the shielding cover 30 is high. In the present embodiment, 1 / 2L1≤L2≤3L1, and L2 is moderate in size, which not only ensures a sufficient heating range to ensure a sufficient amount of high-temperature steam, but also does not cause waste of heat, and the requirement for the temperature resistance of the base 10 and the shielding cover 30 is low.
[0051] Of course, in other embodiments, the outermost circle of the heating body 61 can also be in a square ring shape, an elliptical ring shape, a hexagonal ring shape, or other ring shapes. The bottom wall of the steam generating cavity 11 can also be in a square shape, a hexagonal shape, an elliptical shape, or other arbitrary shapes, which are not limited in the present application.
[0052] Please refer to Figure 2 In the present application, the first heating member 50 is arranged on the bottom wall of the steam generating cavity 11, so that the first heating member 50 transmits heat to the water through the bottom wall of the steam generating cavity 11.
[0053] Further, the first heating member 50 comprises a first heating pipe 51, a heat-conducting disc 52 and a first heat-conducting cover 53. The heat-conducting disc 52 is arranged above the first heating pipe 51. The first heat-conducting cover 53 is arranged as a cover body with an opening facing downward. The first heat-conducting cover 53 is arranged on the upper side of the heat-conducting disc 52. The top surface of the first heat-conducting cover 53 forms at least part of the bottom wall of the steam generation cavity 11 or is arranged below the bottom wall of the steam generation cavity 11. In this way, the heat-conducting disc 52 can uniformly distribute the heat generated by the first heating pipe 51 to the bottom of the steam generation cavity 11, thereby facilitating efficient heating of the water in the steam generation cavity 11 to form steam. The first heat-conducting cover 53 can protect the heat-conducting disc 52 and the first heating pipe 51. The first heat-conducting cover 53 can be made of a material that is easy to clean, thereby facilitating cleaning of the scale formed on the top surface thereof.
[0054] Please refer to Figures 2 to 4 The cover 30 comprises a cover top wall 32 and a cover side wall 33. The cover side wall 33 is connected to the circumferential side of the cover top wall 32 and extends downward. The cover side wall 33 is sealingly connected to the side wall of the steam generation cavity 11. The steam inlet 31 is arranged on the cover top wall 32 and / or the cover side wall 33. In this way, the cover 30 encloses the steam. The second heating member 60 can more efficiently heat the steam, thereby improving the production efficiency of high-temperature steam.
[0055] Further, the lowest part of the steam inlet 31 is higher than the heating main body 61. In this way, the high-temperature steam formed from the part of the cover 30 above the heating main body 61 can directly flow into the cooking cavity 21. The path of the high-temperature steam entering the cooking cavity 21 is short, thereby reducing heat loss.
[0056] Further, the steam inlet 31 is one or more. The flow area of a single steam inlet 31 is S, and S≥10mm 2 In this way, the high-temperature steam can be smoothly discharged from each steam inlet 31. The total flow area of the steam inlets 31 is S1. The surface area of the outside of the cover 30 is S2, and 0.05≤S1 / S2≤0.8. It can be understood that the "total flow area of the steam inlets 31" refers to the sum of the areas of the cross sections of the steam inlets 31 perpendicular to the flow direction of the fluid. If S1 / S2 is too small, the high-temperature steam may not be smoothly discharged. If S1 / S2 is too large, the steam inside the cover 30 is heated by the second heating member 60 for a short time, thereby failing to reach a high temperature, which is difficult to meet the requirements of high-temperature cooking. In the present embodiment, 0.05≤S1 / S2≤0.8, which can ensure that the high-temperature steam in the cover 30 is uniformly and smoothly discharged in a large range, and the high-temperature steam can reach the required temperature.
[0057] The steam inlet 31 can be circular, strip-shaped, square, hexagonal, oval or any other shape, which is not limited in the present application.
[0058] The water tank 40 can be integrally formed on the base 10, or can be arranged separately from the base 10. The present application does not limit this, as long as the water tank 40 can supply water to the steam generating cavity 11.
[0059] In an embodiment, the water tank 40 is integrally formed on the base 10. Specifically, the base 10 is provided with a containing cavity, and the containing cavity is provided with an annular partition plate 12. The annular partition plate 12 divides the containing cavity into the water tank 40 and the steam generating cavity 11. The water tank 40 is annular and surrounds the outside of the steam generating cavity 11. The cover 30 and the annular partition plate 12 are sealingly connected. In this way, the structure of the electric steamer is very simple and easy to process. In this embodiment, the cover side wall 33 of the cover 30 surrounds the outside of the annular partition plate 12, and a sealing member 80 is arranged between the cover side wall 33 and the annular partition plate 12 to achieve the sealing connection between the cover 30 and the annular partition plate 12.
[0060] In addition, since the water tank 40 surrounds the outside of the steam generating cavity 11, a water receiving tray does not need to be arranged between the cooking body 20 and the base 10. Therefore, the condensed water can directly drip into the water tank 40, so that the condensed water can be reused.
[0061] In this embodiment, the bottom wall of the steam generating cavity 11 is lower than the bottom wall of the water tank 40. In this way, it is beneficial for the water in the water tank 40 to flow into the steam generating cavity 11. As shown in FIG. 1, the side wall of the steam generating cavity 11 is provided with a water inlet 14. The water in the water tank 40 flows into the steam generating cavity 11 through the water inlet 14. Figure 2
[0062] In an embodiment, the water control assembly 70 is a float valve. The float valve is lifted and lowered by the buoyancy of water to achieve the on-off control of the water tank 40 and the steam generating cavity 11. Specifically, the float valve is arranged at the water outlet of the water tank 40. When the water level in the steam generating cavity 11 drops below the preset water level line A, the float valve drops to a position to open the water outlet, so that the water tank 40 and the steam generating cavity 11 are connected, and thus the water tank 40 can supply water to the steam generating cavity 11 to make the water level in the steam generating cavity 11 rise. When the water level in the steam generating cavity 11 rises above the water level line, the float valve rises to a position to close the water outlet, so that the water tank 40 and the steam generating cavity 11 are disconnected, and thus the water tank 40 cannot supply water to the steam generating cavity 11. The float valve control method is simple, and can keep the water level in the steam generating cavity 11 below the preset water level line A at all times. The water control assembly 70 can also be a water pump or other water control assembly as long as it can achieve water level control and keep the water level in the steam generating cavity 11 below the preset water level line A at all times.
[0063] Of course, in other embodiments, the electric steamer can also include a water receiving tray arranged between the base 10 and the cooking main body 20, which is used to receive the condensed water generated in the cooking cavity 21. Further, the bottom wall of the water receiving tray is provided with an annular blocking rib, and the portion of the water receiving tray connected to the annular blocking rib forms the blocking cover 30 described above. The steam inlet 31 is arranged on the bottom wall of the water receiving tray and located in the surrounding area of the annular blocking rib. In this way, the water receiving tray can simultaneously have the functions of the blocking cover 30 and the function of receiving condensed water. It can be understood that, for this embodiment, the water receiving tray can also be arranged on the base 10, and the blocking cover 30 can be arranged on the cooking main body 20. Figure 2 With the water tank 40 arranged, the annular partition plate 12 needs to be arranged to have a height greater than the maximum allowable capacity of the water tank 40, so as to avoid the water in the water tank 40 overflowing the annular partition plate 12 when the water receiving tray is not installed.
[0064] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present disclosure.
[0065] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that, for ordinary skilled persons 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.
