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 sufficiently, 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 a bottom heater 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.

[0003] After a long period of cooking, there is usually a large amount of condensed water on the juice receiving tray, which is inconvenient to clean and affects the user experience. CONTENT OF THE INVENTION

[0004] Therefore, it is necessary to provide an electric steamer capable of recycling condensed water.

[0005] An electric steamer includes a base, a cooking main body, and a water receiving tray. The base is provided with a steam generating cavity. The cooking main body is provided with a cooking cavity. The cooking main body is arranged above the base. The water receiving tray is arranged between the base and the cooking main body. The water receiving tray is provided with a steam inlet. The steam inlet is in communication with the steam generating cavity and the cooking cavity. The electric steamer further includes a water tank. A water control assembly is arranged between the water tank and the steam generating cavity. The water control assembly is used to control the on-off between the water tank and the steam generating cavity, so that the water level in the steam generating cavity is below a preset water level line. The electric steamer further includes a first heating member for heating water in the steam generating cavity to generate steam and a second heating member for heating steam. The bottom wall of the water receiving tray is concave to form a water collecting groove. The bottom wall and / or the side wall of the water collecting groove are arranged close to the second heating member.

[0006] The electric steamer provided in the application can generate steam by heating water in the steam generating cavity through the first heating member. The water level in the steam generating cavity can be controlled below the preset water level line by the water control assembly arranged between the water tank and the steam generating cavity, so that steam can be generated quickly. The steam is heated by the second heating member 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 bottom wall and / or the side wall of the water collecting groove are arranged close to the second heating member, the second heating member can also heat the condensed water in the water collecting groove to generate steam, so that the condensed water can be reused, and the problem that it is difficult to clean a large amount of condensed water in the water tray after long-time cooking is avoided. In addition, even if the water in the steam generating cavity has been burned dry, the food can still be cooked by generating steam through heating the water in the water collecting groove, so that the endurance of the electric steamer is improved.

[0007] In one of the embodiments, the second heating member extends into the steam generating cavity from the bottom wall of the steam generating cavity, and at least part of the second heating member is higher than the preset water level line.

[0008] In this way, the second heating member extends into the steam generating cavity, has good heating effect on the steam, and has compact structure.

[0009] In one of the embodiments, the first heating member includes a first heating pipe arranged below the bottom wall of the steam generating cavity, and the first heating pipe is arranged in a ring shape. The second heating member is arranged in the area surrounded by the first heating pipe, and includes a second heating pipe. The second heating pipe includes a terminal and a pipe body. The terminal is arranged below the bottom wall of the steam generating cavity, and the pipe body extends into the steam generating cavity.

[0010] In this way, the first heating member and the second heating member are both arranged on the bottom wall of the steam generating cavity, so that the structure is compact, and the connection with the electric wire is facilitated.

[0011] In one of the embodiments, the second heating member further includes a second heat-conducting cover sleeved on the pipe body. The second heat-conducting cover is a cover body with an opening facing downward. The second heat-conducting cover is integrally formed with the bottom wall of the steam generating cavity, or the lower end of the second heat-conducting cover is sealingly connected with the bottom wall of the steam generating cavity.

[0012] In this way, the second heat-conducting cover can separate the second heating pipe from the water in the steam generating cavity, so that the heating efficiency of the second heating pipe on the steam is not affected by the heating of the water. At the same time, since the second heating pipe is not in contact with the water, the scale is not formed on the surface of the second heating pipe, so that the heating efficiency of the second heating pipe is not affected, and the second heat-conducting cover only has the part in contact with the water, so that the scale on the surface of the second heat-conducting cover is easy to clean.

[0013] In one of the embodiments, the pipe body is arranged in one or more layers along the circumferential direction of the second heat-conducting cover.

[0014] In this way, the pipe body can emit more heat and has a large heating range, which is conducive to heating more steam into high-temperature steam, thereby improving the heating efficiency.

[0015] In one of the embodiments, the water collecting groove is annular, the steam inlet and at least part of the second heating element are located in the area surrounded by the inner annular wall of the water collecting groove, the side wall of the water collecting groove is arranged close to the second heating element, and a gap is formed between the water collecting groove and the second heating element.

[0016] In this way, the steam generated in the steam generating cavity flows to the steam inlet through the gap and enters the cooking cavity through the steam inlet, and the steam is heated by the second heating element to form high-temperature steam. Both the second heating element and the high-temperature steam can heat the condensed water in the water collecting groove, so that the condensed water can be changed into steam to cook the food.

[0017] In one of the embodiments, the bottom wall of the steam generating cavity is provided with a partition plate, the partition plate divides the steam generating cavity into a low-temperature steam generating area communicating with the water tank and a high-temperature steam generating area communicating with the low-temperature steam generating area, and the first heating element and the second heating element are arranged below the bottom wall of the steam generating cavity. The first heating element is located in the projection area of the low-temperature steam generating area, and the second heating element is located in the projection area of the high-temperature steam generating area.

[0018] In this way, the water in the low-temperature steam generating area is heated by the first heating element to generate steam, and the steam is heated by the second heating element to form high-temperature steam when entering the high-temperature steam generating area, and then the high-temperature steam enters the cooking cavity through the steam inlet, thereby realizing high-temperature cooking. Since the first heating element and the second heating element are arranged below the bottom wall of the steam generating cavity, the structure is very compact.

[0019] In one of the embodiments, the water collecting groove extends into the high-temperature steam generating area, and the bottom wall of the water collecting groove is arranged close to the bottom wall of the high-temperature steam generating area.

[0020] In this way, it is ensured that the second heating element can heat the steam in the high-temperature steam generating area and the condensed water in the water collecting groove at the same time.

[0021] In one of the embodiments, the partition plate is arranged as a side wall of the low-temperature steam generating area, and the preset water level line is lower than the upper end of the partition plate.

[0022] Alternatively, the partition plate is arranged as a side wall and a top wall of the low-temperature steam generating area, and the side wall of the low-temperature steam generating area is higher than the area of the preset water level line and / or the top wall of the low-temperature steam generating area is provided with a steam hole.

[0023] In this way, the steam in the low-temperature steam generation area can enter the high-temperature steam generation area, and the water in the low-temperature steam generation area cannot enter the high-temperature steam generation area, thereby avoiding the second heating member from consuming heat to heat the water and affecting the heating effect on the steam.

[0024] In one of the embodiments, the steam inlet is arranged at an upper region of the side wall of the water collecting groove close to the low-temperature steam generation area.

[0025] In this way, the condensed water in the water collecting groove is less likely to overflow from the steam inlet into the high-temperature steam generation area.

[0026] In one of the embodiments, the water pan further comprises a flow guide slope, which is arranged to be inclined relative to the horizontal plane, and the lower end of the flow guide slope is connected to the upper end of the water collecting groove, and the flow guide slope faces the upper space of the water collecting groove.

[0027] In this way, the condensed water first drops onto the flow guide slope and then flows into the water collecting groove through the flow guide slope. It can be seen that the arrangement of the flow guide slope is conducive to the condensed water flowing into the water collecting groove, thereby facilitating the second heating member to heat the condensed water.

[0028] In one of the embodiments, the first heating member and the second heating member are in a split structure, or the first heating member and the second heating member are in an integrated structure.

[0029] The split structure can be processed separately, which is more convenient to process. In addition, the split structure can be arranged to be independently controlled to open and close, thereby being more convenient to use. The integrated structure can be installed integrally, which is more convenient to install. BRIEF DESCRIPTION OF DRAWINGS

[0045] Please refer to Figures 1 to 5The application provides an electric steamer, which comprises a base 10, a cooking main body 20 and a water receiving tray 30. The base 10 is provided with a steam generating cavity 11, the cooking main body 20 is provided with a cooking cavity 21, the cooking main body 20 is arranged above the base 10, the water receiving tray 30 is arranged between the base 10 and the cooking main body 20, the water receiving tray 30 is provided with a steam inlet 31, and the steam inlet 31 is communicated with the steam generating cavity 11 and the cooking cavity 21. The electric steamer further comprises a water tank 50, a water control assembly 40 is arranged between the water tank 50 and the steam generating cavity 11, the water control assembly 40 is used for controlling the on-off between the water tank 50 and the steam generating cavity 11, so that the water level in the steam generating cavity 11 is below a preset water level line A. It can be understood that the "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 electric steamer further comprises a first heating piece 60 used for heating water in the steam generating cavity 11 to generate steam and a second heating piece 70 used for heating steam. The bottom wall of the water receiving tray 30 is concave to form a water collecting groove 32, and the bottom wall and / or the side wall of the water collecting groove 32 is arranged close to the second heating piece 70. In this way, the water in the steam generating cavity 11 is heated by the first heating piece 60 to generate steam, and since the water control assembly 40 is arranged between the water tank 50 and the steam generating cavity 11, the water level in the steam generating cavity 11 can be controlled below the preset water level line A, so that steam can be quickly generated. After the steam is heated by the second heating piece 70 to form high-temperature steam, the high-temperature steam enters the cooking cavity 21 through the steam inlet 31 to cook food, so that high-temperature cooking can be realized. Since the bottom wall and / or the side wall of the water collecting groove 32 is arranged close to the second heating piece 70, the second heating piece 70 can also heat the condensed water in the water collecting groove 32 to generate steam, so that the condensed water can be reused, and the problem that a large amount of condensed water in the water receiving tray 30 is difficult to clean after long-time cooking is avoided. In addition, even if the water in the steam generating cavity 11 has been burned dry, steam can be generated by heating the water in the water collecting groove 32 to cook the food, thereby improving the endurance of the electric steamer.

[0046] In the embodiment, the cooking main body 20 comprises a pot cover 22, the inside of the pot cover 22 forms the cooking cavity 21, and a steaming rack 23 can be arranged in the cooking cavity 21 to support the food to be steamed. In addition, in other embodiments, the cooking main body 20 can also comprise a steaming cage 24, the inside of the steaming cage 24 forms the cooking cavity 21, or the steaming cage 24 and the pot cover 22 enclose the cooking cavity 21, and the application does not limit this, as long as the cooking main body 20 is provided with the cooking cavity 21 capable of accommodating food.

[0047] In an embodiment, the water tank 50 is arranged separately from the base 10, and further, the water tank 50 can be arranged in a detachable structure, i.e., the water tank 50 is detachably connected to the base 10. Of course, the water tank 50 can also be fixedly installed on the base 10. In addition, the water tank 50 can also be integrally formed on the base 10, and the present application does not limit this, as long as the water tank 50 can supply water to the steam generating cavity 11.

[0048] Further, the water control assembly 40 is arranged as a float valve, which is lifted by the buoyancy of water to realize the on-off control of the water tank 50 and the steam generating cavity 11. Specifically, the float valve is arranged at the water outlet of the water tank 50, when the water level in the steam generating cavity 11 falls below the preset water level line A, the float valve falls to a position to open the water outlet, so that the water tank 50 and the steam generating cavity 11 are communicated, so that the water tank 50 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 50 and the steam generating cavity 11 are cut off, so that the water tank 50 will not supply water to the steam generating cavity 11. The float valve control mode is simple, and can make the water level in the steam generating cavity 11 always remain below the preset water level line A. The water control assembly 40 can also be other structures of water control assembly, as long as it can realize water level control, so that the water level in the steam generating cavity 11 always remains below the preset water level line A.

[0049] Further, the water pan 30 further comprises a guide slope 34, the guide slope 34 is arranged obliquely relative to the horizontal plane, and the lower end of the guide slope 34 is connected to the upper end of the water collecting groove 32, and the guide slope 34 faces the upper space of the water collecting groove 32. In this way, the condensed water first falls on the guide slope 34, and is guided by the guide slope 34 to enter the water collecting groove 32. It can be seen that the arrangement of the guide slope 34 is conducive to the condensed water flowing into the water collecting groove 32, thereby facilitating the second heating member 70 to heat the condensed water.

[0050] Further, the inclination angle of the guide slope 34 relative to the horizontal plane is α, and 5°≤α≤60°. It can be understood that if α is too small, it is not conducive to the downward flow of the condensed water; if α is too large, the depth of the water pan 30 is too large, so that the space between the water pan 30 and the steam rack 23 is too large, causing waste of space and heat. In the present embodiment, 5°≤α≤60°, under the condition of ensuring that the condensed water flows smoothly into the water collecting groove 32, the space between the water pan 30 and the steam rack 23 will not be too large, thereby reducing the waste of space and heat. Specifically, α can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, or any other value within the range of 5°-60°.

[0051] Please refer to Figures 1 to 5In one embodiment, the second heating member 70 extends into the steam generating cavity 11 from the bottom wall of the steam generating cavity 11, and at least a portion of the second heating member 70 is higher than the preset water level A. In this way, the second heating member 70 extends into the steam generating cavity 11, and has a good heating effect on the steam, and the structure is compact.

[0052] Further, the first heating member 60 includes a first heating tube 61 arranged below the bottom wall of the steam generating cavity 11, and the first heating tube 61 is arranged in a ring shape. The second heating member 70 includes a second heating tube 71, and the second heating tube 71 includes a terminal 711 arranged below the bottom wall of the steam generating cavity 11 and a tube body 712 extending into the steam generating cavity 11. In this way, the first heating member 60 and the second heating member 70 are arranged on the bottom wall of the steam generating cavity 11, the structure is compact, and the connection with the electric wire is facilitated.

[0053] Further, the tube body 712 is arranged in one or more layers along the circumference of the second heat-conducting cover 72. In this way, the tube body 712 emits more heat, and the heating range is large, which is beneficial to heat more steam into high-temperature steam, thereby improving the heating efficiency. In the present embodiment, the tube body 712 is in a spiral shape, that is, the tube body 712 is arranged in multiple layers along the circumference of the second heat-conducting cover 72. In this way, the heating effect on the steam is better, and the condensed water in the water collecting groove 32 is heated and steam is generated. However, the present application is not limited to this, and in other embodiments, the tube body 712 can also be arranged in a ring shape, which is equivalent to the tube body 712 being arranged in one layer along the circumference of the second heat-conducting cover 72.

[0054] Further, the second heating member 70 further includes a second heat-conducting cover 72 sleeved on the tube body 712, and the second heat-conducting cover 72 is a cover body with an opening facing downward. In one embodiment, the second heat-conducting cover 72 is integrally formed with the bottom wall of the steam generating cavity 11, and in another embodiment, the lower end of the second heat-conducting cover 72 is sealingly connected with the bottom wall of the steam generating cavity 11. In this way, the second heat-conducting cover 72 can separate the second heating tube 71 from the water in the steam generating cavity 11, so as to avoid the heating of the water by the second heating tube 71, thereby affecting the heating efficiency of the steam. At the same time, since the second heating tube 71 is not in contact with the water, the scale is not formed on the surface of the second heating tube 71, thereby not affecting the heating efficiency of the second heating tube 71, and the second heating tube 71 does not need to be cleaned. Only the portion of the second heat-conducting cover 72 in contact with the water can form scale, and therefore the scale on the surface of the second heat-conducting cover 72 is very easy to clean.

[0055] Further, the first heating member 60 further comprises a first heat-conducting disc 62, which is arranged below the bottom wall of the steam generating cavity 11 and above the first heating pipe 61. In this embodiment, the first heat-conducting disc 62 is annular. The first heat-conducting disc 62 can evenly distribute the heat generated by the first heating pipe 61 to the bottom of the steam generating cavity 11, so as to facilitate efficient heating of the water in the steam generating cavity 11 to form steam.

[0056] Further, the water collecting groove 32 is annular, the steam inlet 31 and at least part of the second heating member 70 are located within the surrounding area of the inner annular wall of the water collecting groove 32, the side wall of the water collecting groove 32 is arranged close to the second heating member 70, and there is a gap between the water collecting groove 32 and the second heating member 70. In this way, the steam generated in the steam generating cavity 11 flows to the steam inlet 31 through the gap, and when the steam enters the cooking cavity 21 through the steam inlet 31, the steam is heated by the second heating member 70 to form high-temperature steam. The second heating member 70 and the high-temperature steam can both heat the condensed water in the water collecting groove 32, so that the condensed water can be changed into steam to cook the food.

[0057] In an embodiment, the upper end of the inner annular wall of the water collecting groove 32 is provided with a baffle 33, and the steam inlet 31 is arranged on the baffle 33. However, the upper end of the inner annular wall of the water collecting groove 32 can also not be provided with a baffle 33 in other embodiments, that is, the inner side of the upper end of the inner annular wall of the water collecting groove 32 is open to form the steam inlet 31. In this way, the steam can also enter the cooking cavity 21 through the steam inlet 31.

[0058] In this embodiment, the upper end of the inner annular wall of the water collecting groove 32 is provided with a baffle 33, so that there is a first gap between the side wall of the second heat-conducting cover 72 and the side wall of the water collecting groove 32, and there is a second gap between the top wall of the second heat-conducting cover 72 and the baffle 33. In this way, the steam generated in the steam generating cavity 11 passes through the first gap and the second gap in sequence, and finally enters the cooking cavity 21 from the steam inlet 31. Since the steam inlet 31 is arranged on the baffle 33, as long as the water level of the condensed water in the water collecting groove 32 is lower than the baffle 33, the condensed water will not overflow from the steam inlet 31. At the same time, the flow path of the steam from the generation position (i.e. the water surface in the steam generating cavity 11) to the steam inlet 31 is relatively long, which is conducive to the steam receiving more heat, so as to obtain high-temperature steam with a higher temperature, thereby improving the efficiency of the steam high-temperature cooking, and the high-temperature steam can also consume part of the heat to heat the condensed water in the water collecting groove 32.

[0059] As Figure 3In an embodiment, the second gap H1 is 1 mm≤H1≤20 mm. If the second gap H1 is too small, the flow resistance of the steam at the second gap is large, and it is difficult for the high-temperature steam to enter the cooking cavity 21 through the steam inlet 31. If the second gap H1 is too large, the distance between the high-temperature steam and the food is long, and the heating effect is poor. In this embodiment, 1 mm≤H1≤20 mm, and the size of H1 is moderate. The high-temperature steam can smoothly enter the cooking cavity 21 through the steam inlet 31, and the distance between the high-temperature steam and the food is not too large, so that the heating effect is not affected. Specifically, H1 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, or any other value within the range of 1 mm to 20 mm.

[0060] Further, the distance between the upper end surface of the second heat-conducting cover 72 and the inner bottom wall of the water collecting groove 32 in the vertical direction is H2, the distance between the upper end surface of the baffle 33 and the inner bottom wall of the water collecting groove 32 is H3, and the distance between the upper end surface of the baffle 33 and the preset water level line A is H4. H2

[0061] Further, 3 mm≤H2≤30 mm. H2 is the depth of the water collecting groove 32. If H2 is too large, a large space in the steam generation cavity 11 is occupied, the flow channel of the steam is narrowed, and the water collecting groove 32 is difficult to process. If H2 is too small, the second heating element 70 cannot sufficiently heat the condensate water in the water collecting groove 32 to form steam. 3 mm≤H2≤30 mm, so that H2 is neither too large nor too small. The steam in the steam generation cavity 11 has sufficient flow space, the water collecting groove 32 is not too deep to be difficult to process, and the condensate water in the water collecting groove 32 can be sufficiently heated, so that the condensate water can be effectively utilized. Specifically, H2 can be 3 mm, 5 mm, 8 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, or any other value within the range of 3 mm to 30 mm.

[0062] Further, the first gap L1 is 1 mm≤L1≤5 mm. In this way, the first gap L1 is moderate in size. The water tray 30 is not difficult to take out or place due to a too small gap, and the heating effect of the condensate water is not poor due to a too large gap. Specifically, L1 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, or any other value within the range of 1 mm to 5 mm.

[0063] Further, the width of the water collecting groove 32 is L2, 1mm≤L2≤10mm. In this way, the width of the water collecting groove 32 is appropriate, neither too narrow to cause the condensed water to overflow easily, nor too wide to affect the heating efficiency of the second heating member 70 on the condensed water. Specifically, L2 can be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, or any other value within the range of 1mm-10mm.

[0064] Please refer to Figures 6 to 8 In another embodiment, the bottom wall of the steam generating cavity 11 is provided with a partition plate 13, the partition plate 13 divides the steam generating cavity 11 into a low-temperature steam generating area 111 in communication with the water tank 50 and a high-temperature steam generating area 112 in communication with the low-temperature steam generating area 111, and the first heating member 60 and the second heating member 70 are both arranged below the bottom wall of the steam generating cavity 11, the first heating member 60 is located within the projection area of the low-temperature steam generating area 111, and the second heating member 70 is located within the projection area of the high-temperature steam generating area 112. In this way, the water in the low-temperature steam generating area 111 is heated by the first heating member 60 to generate steam, the steam enters the high-temperature steam generating area 112 and is heated by the second heating member 70 to form high-temperature steam, and the high-temperature steam enters the cooking cavity 21 through the steam inlet 31, thereby realizing high-temperature cooking. Since the first heating member 60 and the second heating member 70 are both arranged below the bottom wall of the steam generating cavity 11, the structure is very compact. Further, the water collecting groove 32 extends into the high-temperature steam generating area 112, and the bottom wall of the water collecting groove 32 is arranged close to the bottom wall of the high-temperature steam generating area 112, so that the second heating member 70 can heat the steam in the high-temperature steam generating area 112 and the condensed water in the water collecting groove 32 at the same time.

[0065] It can be understood that the bottom wall of the water collecting groove 32 can abut against the bottom wall of the high-temperature steam generating area 112, or there can be a gap between the bottom wall of the water collecting groove 32 and the bottom wall of the high-temperature steam generating area 112, thereby allowing steam to flow in the high-temperature steam generating area 112, so that the second heating member 70 can heat the steam in the high-temperature steam generating area 112 more efficiently.

[0066] As Figure 6As shown, in the embodiment, the partition plate 13 is arranged as the side wall and the top wall of the low-temperature steam generation area 111, and the side plate of the low-temperature steam generation area 111 is higher than the region of the preset water level line and / or the top wall of the low-temperature steam generation area 111 is provided with a steam hole 131. In this way, the steam in the low-temperature steam generation area 111 can enter the high-temperature steam generation area 112 through the steam hole 131, and the water in the low-temperature steam generation area 111 will not enter the high-temperature steam generation area 112, thereby avoiding the second heating member 70 consuming heat to heat the water and affecting the heating effect of the steam. However, it is not limited to this. In other embodiments, the partition plate 13 can also be arranged as the side wall of the low-temperature steam generation area 111, and the preset water level line is lower than the upper end of the partition plate 13. In this way, an opening is formed on the upper side of the low-temperature steam generation area 111 and is in communication with the high-temperature steam generation area 112, and the steam can enter the high-temperature steam generation area 112 through the opening. At the same time, the water in the low-temperature steam generation area 111 will not enter the high-temperature steam generation area 112.

[0067] Further, the steam inlet 31 is arranged at the upper region of the side wall of the water collecting groove 32 close to the low-temperature steam generation area 111. In this way, the condensed water in the water collecting groove 32 is not easy to overflow from the steam inlet 31 to the high-temperature steam generation area 112.

[0068] Figure 2 And Figure 6 The first heating member 60 and the second heating member 70 are shown in two different arrangements. Further, the first heating member 60 and the second heating member 70 can be a split structure, that is, the first heating member 60 and the second heating member 70 are two independently arranged structural members, but it is not limited to this. In the embodiment, the first heating member 60 and the second heating member 70 can also be a one-piece structure, that is, the first heating member 60 and the second heating member 70 are one structural member, and the present application does not limit this. It can be understood that the split structure can be processed separately, which is more convenient to process, and the split structure can be arranged to be independently controlled to open and close, so that it is also more convenient to use. The one-piece structure can be installed integrally, which is more convenient to install.

[0069] Please refer to Figures 1 to 5The working principle of the electric steamer provided in the application is as follows: the user adds water into the water tank 50, the water in the water tank 50 is controlled by the water control assembly 40 to flow into the steam generation cavity 11, and the water level in the steam generation cavity 11 is controlled below the preset water level line A. The first heating member 60 starts to work to heat the water to generate low-temperature steam, the low-temperature steam is heated by the second heating member 70 in the process of rising to generate high-temperature steam, the high-temperature steam enters the cooking cavity 21 from the steam inlet 31, so as to realize high-temperature cooking. In the cooking process, the high-temperature steam condenses when encountering the steamer 23, food, the sidewall of the cooking main body 20 and other objects, and the condensed water drops on the water receiving tray 30 and is guided into the water collecting groove 32 through the flow guide slope 34. In the later cooking stage and the heat preservation process, the first heating member 60 can be controlled to heat at a small power or not to work, and the second heating member 70 can be controlled to heat at a large power, so as to heat and evaporate the condensed water in the water collecting groove 32, and the food is supplemented to be cooked. In addition, the heating mode of the second heating member 70 can also be controlled by the temperature measuring device. For example, the temperature measuring device is used to detect the temperature in the cooking cavity 21, when the temperature detected by the temperature measuring device reaches the highest temperature set in the corresponding function, the second heating member 70 stops heating, when the temperature detected by the temperature measuring device drops to the lowest temperature set in the corresponding function, the second heating member 70 continues to heat, and the second heating member 70 works in this way in a cycle, when the time set in the corresponding function is counted, the function cooking is completed.

[0070] In summary, the electric steamer provided in the application can realize the repeated use of the condensed water by heating the condensed water in the water collecting groove 32 by the second heating member 70, which not only facilitates the cleaning of the water receiving tray 30, but also prolongs the endurance of the electric steamer.
