Description

Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and in particular relates to an electric steamer for reducing condensed water. Background Art

[0002] When the hot steam in the existing steamer contacts the steaming cover, it will quickly condense into tiny water droplets that adhere to the inner side of the steaming cover. As time goes by, the condensed water droplets will gather and appear on the food, causing the food to swell and affecting the food quality.

[0003] Based on this prior art, a drip-proof pot cover is disclosed, which includes an outer pot cover and an inner pot cover located below the outer pot cover, and a steam channel is provided on the inner pot cover, so that a jacket air-flowing space is formed between the outer pot cover and the inner pot cover to avoid water droplets from forming under the inner pot cover, and the inner pot cover is used to prevent condensed water in the jacket from dripping on the food. However, the condensed water formed in the jacket air-flowing space of the drip-proof pot cover cannot be discharged, so that the condensed water will flow back along the steam channel and drip on the food in the steamer after accumulating to a certain extent, affecting the cooking quality of the food, and causing odor after long-term use.

[0011] The flow guiding structure comprises a plurality of flow guiding grooves protruding along the outer wall of the inner side wall facing the inner wall surface of the inner side wall, the flow guiding grooves form the return flow channel, and the flow holes are located between adjacent flow guiding grooves.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. A thermal insulation interlayer is formed between the outer cover and the inner cover in the present application, and the inner cover is provided with a flow hole connecting the cooking cavity and the thermal insulation interlayer, so that the steam generated during the cooking process can diffuse into the thermal insulation interlayer through the flow hole. On the one hand, the high-temperature water vapor in the thermal insulation interlayer will have a certain thermal insulation effect on the inner cover, isolating the inner cover from the contact with the external cold air, so that the inner cover still maintains a relatively high temperature, thereby greatly reducing the probability of condensation water on the inner wall surface of the inner cover, avoiding the condensation water from directly dripping on the food on the steaming plate, and ensuring the cooking quality of the food. On the other hand, the arrangement of the inner cover ensures that the condensation water formed on the inner surface of the outer cover will slide along the inner surface of the outer cover and the outer surface of the inner cover when dripping, and will not directly drip onto the food on the steaming plate, thereby ensuring the cooking quality of the food.

[0019] Moreover, the heat preservation interlayer of the present application is provided with a reflux channel for condensed water to reflux, and the reflux channel is arranged to bypass the flow hole, which greatly reduces the probability of condensed water flowing back to the inner side of the inner cover through the flow hole, so that the condensed water can flow down along the reflux channel into the liquid collecting tank on the steaming plate, which greatly reduces the probability of condensed water dripping directly onto the food, thereby ensuring the cooking quality of the food. Furthermore, the arrangement of the liquid collecting tank can improve the structural strength of the steaming plate to a certain extent, improve the ability of the steaming plate to resist deformation, and thus improve its load-bearing performance.

[0020] 2. As a preferred embodiment of the present application, the inner cover includes an inner top cover and an inner side wall extending downward, and the flow hole is arranged on the inner side wall. Compared with the embodiment in which the flow hole is arranged on the inner top cover, the probability of condensed water flowing back along the flow hole to the inner side of the inner cover can be further reduced, thereby reducing the probability of condensed water dripping directly on the food, and improving the cooking quality of the food. Moreover, the flow hole is arranged on the inner side wall, and the steam is discharged from the inner side wall of the flow hole and enters the thermal insulation interlayer, so that the steam can form a three-dimensional surround on the inner cover, thereby improving the thermal insulation effect of the inner cover and further reducing the probability of condensed water on the inner surface of the inner cover.

[0021] 3. As a preferred embodiment of the present application, the inner cover includes an inner top cover and an inner side wall extending downward, and the inner side wall is provided with a guide structure to form a reflux channel on the outer wall surface of the inner side wall to drain the condensed water in the thermal insulation interlayer and make it flow to the liquid collection tank in a concentrated manner, which not only facilitates the collection of condensed water and reduces the probability of contact between condensed water and food, but also avoids the accumulation of bacteria and the generation of odor caused by the accumulation of condensed water in the thermal insulation interlayer, thereby improving the user experience.

[0022] Furthermore, the flow-guiding structure is a flow-guiding rib provided on the outer wall surface of the inner side wall, and the flow-guiding rib protrudes from the outer wall surface to form a reflux channel between two adjacent flow-guiding ribs. During use, the condensed water formed on the inner wall surface of the outer cover drips onto the inner cover and slides down. After encountering the flow-guiding rib, the condensed water is diverted into the reflux channels on both sides. On the one hand, it can prevent the condensed water from flowing back to the inner side of the inner cover through the flow holes penetrated by the flow-guiding rib, and on the other hand, it can converge the condensed water, increase the flow speed of the condensed water, facilitate the collection of the condensed water by the liquid collecting tank, and avoid the condensed water from accumulating on the outer surface of the inner cover for a long time, which causes the temperature of the outer surface of the inner cover to decrease, thereby further reducing the formation of condensed water on the inner surface of the inner cover, and effectively protecting the food. Furthermore, the setting of the flow-guiding rib can enhance the structural strength of the inner cover and reduce the probability of deformation of the inner cover under the fumigation of high-temperature steam.

[0023] 4. As a preferred embodiment of the present application, the inner cover includes an inner top cover and an inner side wall extending downward, and the inner wall surface of the inner side wall is provided with a guide groove. The arrangement of the guide groove can drain a small amount of condensed water formed on the inner side wall and / or a small amount of condensed water entering the inner side of the inner cover through the flow hole, so that it drips into the water collection tank, thereby greatly reducing the probability of food that directly contacts the inner wall surface of the inner side wall being soaked, thereby improving the cooking quality of the food.

[0024] 5. As a preferred embodiment of the present application, the outer cover is provided with a steam exhaust hole, and the steam exhaust hole is arranged away from the flow hole, so that the hot steam can experience the longest possible flow path when it enters the thermal insulation interlayer through the flow hole and is discharged from the thermal insulation interlayer through the steam exhaust hole, thereby extending the residence time of the hot steam in the thermal insulation interlayer, thereby producing a better thermal insulation effect on the inner cover and reducing the probability of condensation water forming on the inner surface of the inner cover.

[0025] 6. As a preferred embodiment of the present application, the steaming plate is provided with a drainage hole connected to the liquid collecting tank. The condensed water falling into the liquid collecting tank can flow step by step to the lower steaming plate through the drainage hole, thereby avoiding excessive accumulation of condensed water on the upper steaming plate, thereby avoiding the food on the upper steaming plate from being soaked, and when the condensed water flows downward step by step and is recycled into the steam generating chamber of the electric steamer, the condensed water can be recycled.

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, an electric steamer for reducing condensed water comprises a steaming cover assembly and at least one layer of steaming sheet 5 located below the steaming cover assembly, the steaming cover assembly and the steaming sheet 5 enclose a cooking cavity, the steaming cover assembly comprises an outer cover 2 and an inner cover 1, a thermal insulation interlayer 3 is formed between the outer cover 2 and the inner cover 1, the inner cover 1 is provided with a flow hole 14 connecting the cooking cavity and the thermal insulation interlayer 3, the thermal insulation interlayer 3 is provided with a reflux channel 7 for reflux of condensed water 4, the reflux channel 7 is arranged to bypass the flow hole 14, and the steaming sheet 5 is provided with a liquid collecting tank 51 corresponding to the reflux channel 7.

[0048] A thermal insulation interlayer 3 is formed between the outer cover 2 and the inner cover 1 in the present application, and the inner cover 1 is provided with a flow hole 14 connecting the cooking cavity and the thermal insulation interlayer 3, so that the steam generated during the cooking process can diffuse into the thermal insulation interlayer 3 through the flow hole 14. On the one hand, the high-temperature water vapor in the thermal insulation interlayer 3 will have a certain thermal insulation effect on the inner cover 1, isolating the inner cover 1 from the contact with the external cold air, so that the inner cover 1 still maintains a relatively high temperature, thereby greatly reducing the probability of condensation water 4 on the inner wall surface of the inner cover 1, avoiding the condensation water 4 from directly dripping onto the food on the steaming plate 5, thereby ensuring the cooking quality of the food. On the other hand, the arrangement of the inner cover 1 ensures that the condensation water 4 formed on the inner surface of the outer cover 2 will slide along the inner surface of the outer cover 2 and the outer surface of the inner cover 1 when dripping, and will not directly drip onto the food on the steaming plate 5, thereby ensuring the cooking quality of the food.

[0049] Moreover, the heat-insulating interlayer 3 of the present application is provided with a reflux channel 7 for the reflux of the condensed water 4, and the reflux channel 7 is arranged to bypass the flow hole 14, which greatly reduces the probability of the condensed water 4 flowing back to the inner side of the inner cover 1 through the flow hole 14, so that the condensed water 4 can flow down along the reflux channel 7 and enter the liquid collecting tank 51 on the steaming plate 5, which greatly reduces the probability of the condensed water 4 dripping directly onto the food, thereby ensuring the cooking quality of the food. Furthermore, the arrangement of the liquid collecting tank 51 can improve the structural strength of the steaming plate 5 to a certain extent, improve the ability of the steaming plate 5 to resist deformation, and thus improve its load-bearing performance.

[0050] In the present application, the communication mode between the reflux channel 7 in the thermal insulation interlayer 3 and the liquid collecting tank 51 may adopt any one of the following embodiments:

[0051] Implementation method 1: Figure 3 and Figure 5 As shown, a reflux gap 8 is formed between the outer cover 2 and the inner cover 1 for reflux of the condensed water 4. Specifically, the outer cover 2 includes an outer top cover 21 and an outer side wall 22 that is fixedly connected to the periphery of the outer top cover 21 and extends downward, and the inner cover 1 includes an inner top cover 11 and an inner side wall 12 that is fixedly connected to the periphery of the inner top cover 11 and extends downward, and a reflux gap 8 is formed between the bottom of the outer side wall 22 and the bottom of the inner side wall 12, and the condensed water 4 in the thermal insulation interlayer 3 falls into the liquid collecting tank 51 through the reflux channel 7 and the reflux gap 8.

[0052] This first embodiment can not only simplify the structural design of the outer cover 2 and the inner cover 1 , but also facilitate the rapid backflow of the condensed water 4 . In addition, it can also significantly reduce the probability of the condensed water 4 remaining in the thermal insulation interlayer 3 .

[0053] Embodiment 2: The outer periphery of the inner cover 1 is provided with a reflux hole for reflux of the condensed water 4. Specifically, the inner cover 1 comprises an inner top cover 11, an inner side wall 12 fixedly connected to the periphery of the inner top cover 11 and extending downward, and an outer flange fixedly connected to the bottom of the inner side wall 12 and folded outward to abut against the outer cover 2, and the outer flange is provided with a plurality of reflux holes at intervals along its circumference, and the condensed water 4 in the thermal insulation interlayer 3 falls into the liquid collecting tank 51 through the reflux channel 7 and the reflux holes.

[0054] Embodiment 3: The inner periphery of the outer cover 2 is provided with a reflux hole for reflux of the condensed water 4. Specifically, the outer cover 2 includes an outer top cover 21, an outer side wall 22 fixedly connected to the periphery of the outer top cover 21 and extending downward, and an inner flange fixedly connected to the bottom of the outer side wall 22 and folded inward to abut against the inner cover 1. The inner flange is provided with a plurality of reflux holes at intervals along its circumference, and the condensed water 4 outside the thermal insulation interlayer 3 falls into the liquid collecting tank 51 through the reflux channel 7 and the reflux holes.

[0055] The location of the flow hole 14 in the present application may be any one of the following embodiments:

[0056] Embodiment 4: The inner cover 1 includes an inner top cover 11 and an inner side wall 12 which is fixedly connected to the periphery of the inner top cover 11 and extends downward, and the flow hole 14 is located on the inner top cover 11 .

[0057] Implementation method five: Figure 3 , Figure 4 and Figure 6 As shown, the inner cover 1 includes an inner top cover 11 and an inner side wall 12 that is fixedly connected to the periphery of the inner top cover 11 and extends downward, and the flow hole 14 is located on the inner side wall 12. Compared with the fourth embodiment, the probability of the condensed water 4 flowing back to the inner side of the inner cover 1 along the flow hole 14 can be further reduced, thereby reducing the probability of the condensed water 4 dripping directly on the food, and improving the cooking quality of the food. Moreover, the flow hole 14 is arranged on the inner side wall 12, and the steam is discharged from the inner side wall 12 of the flow hole 14 and enters the thermal insulation interlayer 3, so that the steam can form a three-dimensional surround on the inner cover 1, thereby improving the effect of heat insulation and heat preservation on the inner cover 1, and further reducing the probability of condensed water 4 on the inner surface of the inner cover 1.

[0058] Embodiment 6: The inner cover 1 comprises an inner top cover 11 and an inner side wall 12 which is fixedly connected to the periphery of the inner top cover 11 and extends downward. Both the inner top cover 11 and the inner side wall 12 are provided with flow holes 14 .

[0059] The location and form of the reflux channel 7 in the present application may be any one of the following embodiments:

[0060] Embodiment 7: The outer cover 2 comprises an outer top cover 21 and an outer side wall 22 which is fixedly connected to the periphery of the outer top cover 21 and extends downward. The inner surface of the outer side wall 22 is provided with a plurality of grooves at intervals, and the grooves constitute the reflux channel 7 .

[0061] Implementation method eight: Figures 3 to 6 As shown, the inner cover 1 includes an inner top cover 11 and an inner side wall 12 which is fixedly connected to the periphery of the inner top cover 11 and extends downward, and a flow guiding structure is provided on the inner side wall 12 to form a reflux channel 7 on the outer wall surface of the inner side wall 12. Such a configuration can drain the condensed water 4 in the thermal insulation interlayer 3 and make it flow to the liquid collecting tank 51 in a centralized manner, which not only facilitates the collection of the condensed water 4 and reduces the probability of the condensed water 4 contacting the food, but also avoids the accumulation of bacteria and the generation of odor caused by the accumulation of the condensed water 4 in the thermal insulation interlayer 3, thereby improving the user experience.

[0062] Example 1: Figure 3 , Figure 4 and Figure 6 As shown, the flow guiding structure includes a flow guiding rib 16 which is arranged on the outer wall surface higher than the inner wall 12 , and a return flow channel 7 is formed on both sides of the flow guiding rib 16 , and the flow hole 14 passes through the flow guiding rib 16 .

[0063] In the present embodiment 1, the flow guiding structure is a flow guiding rib 16 provided on the outer wall surface of the inner side wall 12, and the flow guiding rib 16 is provided to protrude from the outer wall surface to form a reflux channel 7 between two adjacent flow guiding ribs 16. During use, the condensed water 4 formed on the inner wall surface of the outer cover 2 drips onto the inner cover 1 and slides down. After encountering the flow guiding rib 16, the condensed water 4 is diverted into the reflux channel 7 on both sides. On the one hand, it can prevent the condensed water 4 from flowing back to the inner side of the inner cover 1 through the flow holes 14 penetrated by the flow guiding rib 16, and on the other hand, it can converge the condensed water 4 and increase the flow speed of the condensed water 4, which is convenient for the liquid collecting groove 51 to collect the condensed water 4, and avoids the condensed water 4 from accumulating on the outer surface of the inner cover 1 for a long time and causing the temperature of the outer surface of the inner cover 1 to decrease, thereby further reducing the formation of condensed water 4 on the inner surface of the inner cover 1, and effectively protecting the food. Furthermore, the provision of the guide ribs 16 can enhance the structural strength of the inner cover 1 and reduce the probability of deformation of the inner cover 1 under the fumigation of high-temperature steam.

[0064] Furthermore, the inner cover 1 includes an inner top cover 11 and an inner side wall 12 that is fixedly connected to the periphery of the inner top cover 11 and extends downward, and a guide groove 13 is provided on the inner wall surface of the inner side wall 12. The arrangement of the guide groove 13 can drain a small amount of condensed water 4 formed on the inner side wall 12 and / or a small amount of condensed water 4 that enters the inner side of the inner cover 1 through the flow hole 14, so that it drips into the water collection tank, greatly reducing the probability of food that directly contacts the inner wall surface of the inner side wall 12 being soaked, thereby improving the cooking quality of the food.

[0065] As a preference, Figure 6 As shown, the guide groove 13 is a concave structure formed on the inner wall surface of the inner side wall 12 , and the guide ribs 16 and the concave structure correspond one to one along the inner and outer directions of the inner side wall 12 to facilitate the processing and manufacturing of the inner cover 1 .

[0066] Embodiment 2: The flow guiding structure comprises a plurality of flow guiding grooves protruding along the outer wall of the inner side wall 12 and facing the inner wall surface of the inner side wall 12 , the flow guiding grooves form the return channel 7 , and the flow holes 14 are located between adjacent flow guiding grooves.

[0067] In the second embodiment, the flow hole 14 is located between two adjacent flow guide grooves, the flow guide groove is recessed inward relative to the outer wall surface of the inner side wall 12, and the outer end of the flow hole 14 is substantially flush with the outer wall surface of the inner side wall 12. During use, even if the condensed water 4 enters the inner side of the inner cover 1 through the flow hole 14, because the flow guide groove protrudes toward the inner side of the inner cover 1, even if the food on the steaming sheet 5 contacts the inner wall surface of the inner side wall 12, the contact part is the inner wall surface portion corresponding to the position of the flow guide groove. Because the flow hole 14 is located on both sides of the flow guide groove, the condensed water 4 entering the inner cover 1 through the flow hole 14 will not drip onto the food when it flows down along the inner wall surface of the inner side wall 12, thereby protecting the food.

[0068] The outer cover 2 in the present application is provided with a steam exhaust hole 23 to facilitate the exhaust of the steam entering the thermal insulation interlayer 3. The steam exhaust hole 23 in the present application can be arranged in any one of the following embodiments:

[0069] Implementation method nine: Figure 1 and Figure 2 As shown, the outer cover 2 includes an outer top cover 21 and an outer side wall 22 that is fixedly connected to the periphery of the outer top cover 21 and extends downward, and the outer top cover 21 is provided with a steam exhaust hole 23. The hot steam rises upward as a whole, and the steam exhaust hole 23 is provided on the outer top cover 21, which can follow the flow direction of the hot steam and facilitate the smooth discharge of the hot steam. When the flow hole 14 is provided on the inner side wall 12 of the inner cover 1, by providing the steam exhaust hole 23 on the outer top cover 21, the flow path of the steam can be extended to a certain extent, so that the retention time of the steam in the thermal insulation interlayer 3 is relatively extended, thereby improving the thermal insulation effect of the inner cover 1 and reducing the formation of condensed water 4 on the inner wall surface of the inner cover 1.

[0070] Embodiment 10: The inner cover 1 has a plurality of inner side walls 12, some of which are provided with flow holes 14, the outer cover 2 includes an outer top cover 21 and a plurality of outer side walls 22 fixedly connected to the periphery of the outer top cover 21 and extending downward, some of the outer side walls 22 are provided with exhaust holes 23, and the outer side walls 22 provided with the exhaust holes 23 are arranged opposite to the inner side walls 12 without the flow holes 14. Such an arrangement can avoid the exhaust holes 23 facing the steam holes, thereby extending the flow path of the steam in the thermal insulation interlayer 3 and improving the thermal insulation performance of the inner cover 1.

[0071] For example, in one example, the inner cover 1 includes an inner top cover 11 and four inner side walls 12 fixedly connected to the inner top cover 11 and extending downward, wherein two opposite inner side walls 12 are provided with flow holes 14, and the other two opposite inner side walls 12 are not provided with flow holes 14. Correspondingly, the outer cover 2 includes an outer top cover 21 and four outer side walls 22 fixedly connected to the outer top cover 21 and extending downward, wherein two outer side walls 22 opposite to the inner side walls 12 without flow holes 14 are provided with exhaust holes 23.

[0072] As a preferred implementation of the present application, Figure 2 As shown, the steaming plate 5 is provided with a drainage hole 52 connected to the liquid collecting tank 51. The condensed water 4 falling into the liquid collecting tank 51 can flow step by step to the lower steaming plate 5 through the drainage hole 52, thereby avoiding excessive accumulation of the condensed water 4 on the upper steaming plate 5, thereby preventing the food on the upper steaming plate 5 from being soaked, and when the condensed water 4 flows down step by step and is recycled into the steam generating chamber of the electric steamer, the condensed water 4 can be recycled.

[0073] Furthermore, if Figure 2As shown, the portion of the steaming plate 5 close to its outer edge is recessed downward to form an annular and interconnected liquid collecting groove 51, so as to collect the condensed water 4 flowing down from various positions in the thermal insulation interlayer 3.

[0074] As a preferred implementation of the present application, Figures 1 to 3 As shown, the steaming cover assembly also includes a handle 6, the inner cover 1 is provided with a first mounting hole 17, the outer cover 2 is provided with a second mounting hole 24, and the handle 6 is provided with a third mounting hole. The inner cover 1, the outer cover 2 and the handle 6 are connected by fasteners passing through the first mounting hole 17, the second mounting hole 24 and the third mounting hole.

[0075] In this embodiment, the inner cover 1, the outer cover 2 and the handle 6 are formed separately, which facilitates their respective processing and manufacturing, and the three are connected by fasteners passing through the first mounting hole 17, the second mounting hole 24 and the third mounting hole, which helps to improve the assembly efficiency of the three.
