Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of food processing and relates to a rice cooking utensil. Background Art
[0002] The prior art has an electric rice cooker with an anti-overflow structure, which includes an inner cover, a heat-insulating seat plate and a steam valve assembly; the heat-insulating seat plate is located above the inner cover, and a steam channel is formed between the two; the inner cover is provided with a steam inlet connected to one end of the steam channel, the steam valve assembly is provided with a steam valve port connected to the other end of the steam channel, and the orthographic projection of the steam valve port on the inner cover is located outside the steam inlet. Compared with the prior art, the anti-overflow structure of the electric rice cooker adds a steam channel between the inner cover and the heat-insulating seat plate, so that steam and bubbles can pass through according to a set path and then be discharged to the steam valve, thereby improving the overall anti-overflow capability of bubble breaking, and at the same time can improve the cooking speed of the product.
[0003] In the electric rice cooker of the above structure, when the steam passes through the steam channel, the temperature of the upper surface of the inner cover will be increased to a certain extent, thereby reducing the temperature difference between the upper and lower surfaces of the inner cover and reducing the generation of condensed water on the lower surface of the inner cover. However, after the steam passes through the steam inlet, the steam tends to flow mainly in one direction, which tends to cause a large temperature difference between various parts of the upper surface of the inner cover, and a large amount of condensed water is still likely to appear in some parts of the lower surface of the inner cover. Summary of the invention
[0004] The utility model proposes a rice cooking utensil in view of the problems existing in the prior art, aiming to overcome the defect that a large amount of condensed water is easily generated at a local position of the lower surface of the inner cover of the existing electric rice cooker.
[0005] The utility model is achieved in this way:
[0006] A rice cooking utensil, comprising a pot cover and a pot body, wherein the pot cover comprises an inner cover, the inner cover is provided with an air inlet, and the pot cover is provided with an exhaust port and a steam channel, so that steam in the pot body enters the steam channel from the air inlet and is discharged from the pot cover from the exhaust port;
[0007] The bottom wall of the steam channel is located on the inner cover, and the pot cover is provided with diverter ribs so that the steam in the pot body flows to different directions of the steam channel after passing through the air inlet.
[0008] During cooking, the steam generated in the pot body enters the steam channel through the air inlet. Since the bottom wall of the steam channel is located on the inner cover, the steam can directly contact the upper surface of the inner cover in the steam channel, thereby increasing the temperature of the upper surface of the inner cover and reducing the temperature difference between the upper and lower surfaces of the inner cover, which is beneficial for maintaining the lower surface of the inner cover at a higher temperature and reducing the heat absorbed by the inner cover from the steam in contact with the lower surface of the inner cover, thereby reducing the generation of condensation water on the lower surface of the inner cover and reducing the reflux of condensation water into the cooking cavity in the pot body, which has an adverse effect on the taste of rice.
[0009] The diverter ribs can forcibly divert the steam after passing through the air inlet to different directions of the steam channel, preventing the steam from flowing mainly in one direction. During the flow of steam in the steam channel, the steam temperature will gradually drop. The higher the steam temperature passing through the corresponding position on the upper surface of the inner cover, the higher the corresponding temperature will be, ensuring that the steam can be better diverted to different directions, so that the higher temperature steam can be more evenly diverted to different positions on the upper surface of the inner cover, making the upper surface of the inner cover more evenly heated, reducing local high and low temperature phenomena, and making it less likely for excessive local condensation water to form on the lower surface of the inner cover, thereby improving the cooking effect.
[0010] Preferably, the air inlet includes at least a first inlet and a second inlet, and the first inlet and the second inlet are located on different sides of the diverter rib so that the steam flows in different directions after passing through the first inlet and the second inlet; independent inlets can more accurately control the flow rate of steam in different directions. For example, if the two inlets are the same size, the amount of steam passing through the two inlets per unit time can be better controlled, and two inlets of the same size can be stamped out more accurately and quickly when processing the inner cover.
[0011] Alternatively, the air inlet is a single hole, and the diverter rib spans over the air inlet. The diverter rib can divide the air inlet into two parts, and the steam passing through the two parts can flow in different directions.
[0012] Preferably, the pot cover has a dividing rib, which divides the steam channel into a first channel and a second channel, the first inlet corresponds to the first channel, and the second inlet corresponds to the second channel. Steam flowing in different directions after passing through the first inlet and the second inlet has its own independent channel, avoiding mutual interference, which is conducive to improving the balance of the temperature rise on the upper surface of the inner cover.
[0013] Preferably, the first channel and the second channel in the steam channel are annular, the first channel surrounds the outside of the second channel, and the flow directions of steam in the first channel and the second channel are opposite. In this way, the starting end of the first channel corresponds to the end of the second channel, and the end of the first channel corresponds to the starting end of the second channel. The temperature of steam is higher at the starting end of the steam channel and lower at the end of the steam channel. Steam enters the first channel and flows from its starting end to the end, and steam enters the second channel and flows from its starting end to the end. Since the starting position of the first channel corresponds to the end position of the second channel, the heat of the upper surface of the inner cover at the corresponding position of the starting end of the first channel can be quickly transferred to the corresponding position of the end of the second channel, and the heat of the upper surface of the inner cover at the corresponding position of the starting end of the second channel can be quickly transferred to the corresponding position of the end of the first channel, thereby balancing the temperature difference between the starting end and the end of each channel, and the temperature difference of the inner cover corresponding to the channel between the starting end and the end of each channel will also be balanced accordingly, thereby improving the temperature balance of each position on the upper surface of the inner cover, and further reducing the possibility of local condensation water on the lower surface of the inner cover.
[0014] Preferably, the width of the first channel is smaller than the width of the second channel. Since the first channel is located outside the second channel, the corresponding length of the first channel is longer and the width of the first channel is smaller, which is conducive to the area of the inner cover in the first channel and the area in the second channel being equal, so that the inner cover absorbs the heat of the steam in the first channel and the steam in the second channel more evenly, which is conducive to making the temperature of the steam at the end of the first channel and the steam at the end of the second channel equal, further reducing the temperature difference at various positions on the upper surface of the inner cover, and reducing the possibility of local condensation water on the lower surface of the inner cover.
[0015] Preferably, the pot cover further comprises a cover plate arranged above the inner cover, and a steam valve arranged above the cover plate, the diverter rib is located on the cover plate, the exhaust port is located on the steam valve, the cover plate has an exhaust port, and the exhaust port is connected to the steam channel and the exhaust port. The cover plate can be arranged independently of the upper cover of the pot cover, and the cover plate and the inner cover together form a steam channel, which can reduce the heat loss of the steam in the steam channel, so that the upper surface of the inner cover can absorb more steam heat, reduce the temperature difference between the upper surface and the lower surface of the inner cover, and reduce the generation of condensed water on the lower surface of the inner cover.
[0016] Preferably, the cover plate has outer ribs, inner ribs and separation ribs protruding downward, a first channel is formed between the outer ribs and the separation ribs, a second channel is formed between the inner ribs and the separation ribs, and the diverter ribs extend from the inner ribs to the outer ribs. The outer ribs, inner ribs and separation ribs are easy to process, and the first channel and the second channel can be formed after the cover plate and the inner cover are assembled, and the structure is relatively simple.
[0017] Preferably, the gas outlet includes a first outlet and a second outlet corresponding to the first channel and the second channel respectively, and the distance between the first outlet and the second outlet is smaller than the radius of the cover plate. The smaller distance between the first outlet and the second outlet is conducive to gathering the steam of the two outlets through a smaller steam valve.
[0018] Preferably, the bottom wall area of the steam channel is greater than 50% of the area of the upper surface of the inner cover. The larger upper surface of the inner cover can be directly heated by the steam in the first channel and the second channel, which can more comprehensively and directly increase the temperature of the upper surface of the inner cover, reduce the occurrence of local low temperature in the inner cover, and reduce the possibility of local condensation water on the lower surface of the inner cover.
[0019] Preferably, the inner cover is provided with a water collecting member, and the water collecting member has a receiving cavity with an opening facing upward, so that the condensed water flowing out of the air inlet falls into the receiving cavity, thereby preventing the condensed water in the steam channel from flowing back into the cooking cavity of the pot body.
[0020] The rice cooking utensil provided by the utility model has a diverter rib which can forcibly divert the steam after passing through the air inlet to different directions of the steam channel, thereby preventing the steam from mainly flowing in one direction, so that the higher temperature steam can be more evenly diverted to different positions on the upper surface of the inner cover, so that the upper surface of the inner cover is heated more evenly, reducing local high temperature and local low temperature phenomena, making it less likely for excessive local condensation water to form on the lower surface of the inner cover, thereby improving the cooking effect.

DETAILED DESCRIPTION
[0028] The following will further describe the specific implementation of the utility model in combination with the accompanying drawings of the embodiments, so that the technical solution of the utility model is easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0029] This embodiment provides an electric rice cooker, which is an application of the innovative solution of the utility model on an electric rice cooker. The innovative solution of the utility model can also be used on cooking utensils such as pressure cookers that can be used to cook rice.
[0030] like Figure 1 As shown in Figure 5, the rice cooker includes a pot cover 100 and a pot body 200, wherein the pot cover 100 includes an inner cover 110, wherein the inner cover 110 has an air inlet, and the pot cover 100 has an exhaust port 131 and a steam channel 150, so that the steam in the pot body 200 enters the steam channel 150 from the air inlet and is discharged from the pot cover 100 from the exhaust port 131, and the bottom wall of the steam channel 150 is located on the inner cover 110.
[0031] During cooking, the steam generated in the pot body 200 enters the steam channel 150 through the air inlet. Since the bottom wall of the steam channel 150 is located on the inner cover 110, the steam can directly contact the upper surface of the inner cover 110 in the steam channel 150, thereby increasing the temperature of the upper surface of the inner cover 110 and reducing the temperature difference between the upper and lower surfaces of the inner cover 110, which is beneficial for maintaining the lower surface of the inner cover 110 at a higher temperature and reducing the heat absorbed by the inner cover 110 from the steam in contact with the lower surface of the inner cover 110, thereby reducing the generation of condensation water on the lower surface of the inner cover 110 and reducing the reflux of condensation water to the cooking cavity 210 in the pot body 200, which has an adverse effect on the taste of rice.
[0032] like Figure 3 , 5As shown, the pot cover 100 has a diverter rib 121, so that the steam in the pot body 200 flows to different directions of the steam channel 150 after passing through the air inlet. The diverter rib 121 can forcibly divert the steam after passing through the air inlet to different directions of the steam channel 150, avoiding the situation where the steam mainly flows in one direction. During the flow of steam in the steam channel 150, the steam temperature will gradually decrease. The higher the steam temperature passing through the corresponding position on the upper surface of the inner cover 110, the higher its corresponding temperature will be, ensuring that the steam can be better diverted to different directions, so that the higher temperature steam can be more evenly diverted to different positions on the upper surface of the inner cover 110, so that the upper surface of the inner cover 110 is heated more evenly, reducing the phenomenon of local high temperature and local low temperature, making it difficult for the lower surface of the inner cover 110 to produce too much local condensed water, and improving the cooking effect.
[0033] like Figure 3 , 4 As shown, the air inlet includes a first inlet 111 and a second inlet 112, and the first inlet 111 and the second inlet 112 are located on different sides of the diverter rib 121, so that the steam flows in different directions after passing through the first inlet 111 and the second inlet 112. The diverter rib 121 can mix the steam entering the first inlet 111 and the steam entering the second inlet 112 and flow in the same direction. Independent inlets can more accurately control the flow rate of steam in different directions. For example, if the two inlets are the same size, the amount of steam passing through the two inlets per unit time can be better controlled. When processing the inner cover 110, two inlets of the same size can be stamped and formed more accurately and quickly. The air inlet of this embodiment includes two inlets. In other optional embodiments, the air inlet may also include three or more independent inlets.
[0034] In other optional embodiments, the air inlet may also be a single hole, and the diverter rib 121 spans over the air inlet. The diverter rib 121 can divide the air inlet into two parts, and the steam passing through the two parts can flow in different directions.
[0035] like Figure 3 As shown in FIG. 5 , the pot cover 100 has a separation rib 122, and the separation rib 122 separates the steam channel 150 into a first channel 151 and a second channel 152. The first inlet 111 corresponds to the first channel 151, and the second inlet 112 corresponds to the second channel 152. The steam flowing in different directions after passing through the first inlet 111 and the second inlet 112 has its own independent channel to avoid mutual interference, which is conducive to improving the balance of the temperature rise on the upper surface of the inner cover 110. In other optional embodiments, such as Figure 6 As shown, the steam channel 150 may also be divided into two areas only by the dividing rib 121 .
[0036] like Figure 3 , 5 As shown, the first channel 151 and the second channel 152 are annular, the first channel 151 surrounds the outside of the second channel 152, and the flow directions of steam in the first channel 151 and the second channel 152 are opposite. Figure 5 From the perspective of the steam, the flow direction of the steam in the first channel 151 is counterclockwise, and the flow direction of the steam in the second channel 152 is clockwise. In this way, the beginning of the first channel 151 corresponds to the end of the second channel 152, and the end of the first channel 151 corresponds to the beginning of the second channel 152. The temperature of the steam is higher at the beginning of the steam channel 150 and lower at the end of the steam channel 150. The steam enters the first channel 151 and flows from the beginning to the end, and the steam enters the second channel 152 and flows from the beginning to the end. Since the starting position of the first channel 151 and the ending position of the second channel 152 correspond to each other, the heat at the corresponding position on the upper surface of the inner cover 110 at the starting end of the first channel 151 can be quickly transferred to the corresponding position at the end of the second channel 152, and the heat at the corresponding position on the upper surface of the inner cover 110 at the starting end of the second channel 152 can be quickly transferred to the corresponding position at the end of the first channel 151, thereby balancing the temperature difference between the starting and ending ends of each channel, and the temperature difference of the inner cover 110 corresponding to the channel between the starting and ending ends of each channel will also be balanced accordingly, thereby improving the temperature uniformity of each position on the upper surface of the inner cover 110, and further reducing the possibility of local condensation water generation on the lower surface of the inner cover 110.
[0037] like Figure 5 As shown, the width of the first channel 151 is smaller than the width of the second channel 152. Since the first channel 151 is located outside the second channel 152, the corresponding length of the first channel 151 is longer and the width of the first channel 151 is smaller, which is conducive to the area of the inner cover 110 in the first channel 151 and the area in the second channel 152 being the same, so that the inner cover 110 absorbs the heat of the steam in the first channel 151 and the steam in the second channel 152 more evenly, which is conducive to making the steam temperature at the end of the first channel 151 and the steam temperature at the end of the second channel 152 being the same, further reducing the temperature difference at various positions on the upper surface of the inner cover 110, and reducing the possibility of condensed water locally generated on the lower surface of the inner cover 110. In this embodiment, the area of the inner cover 110 in the first channel 151 and the area in the second channel 152 are the same, and the corresponding apertures of the first inlet 111 and the second inlet 112 are also the same. In other optional embodiments, the area of the inner cover 110 in the first channel 151 may be larger or smaller than the area in the second channel 152 , and the corresponding aperture of the first inlet 111 may also be larger or smaller than the aperture of the second inlet 112 .
[0038] like Figure 2As shown in FIG. 4, the pot cover 100 further includes a cover plate 120 disposed above the inner cover 110, and a steam valve 130 disposed above the cover plate 120, the diverter rib 121 is located on the cover plate 120, the exhaust port 131 is located on the steam valve 130, and the cover plate 120 has an exhaust port 123, and the exhaust port 123 communicates with the steam channel 150 and the exhaust port 131. The cover plate 120 can be disposed independently of the upper cover 140 of the pot cover 100, and the steam channel 150 is formed by the cover plate 120 and the inner cover 110, so that the heat loss of the steam in the steam channel 150 can be reduced, so that the upper surface of the inner cover 110 can absorb more steam heat, reduce the temperature difference between the upper surface and the lower surface of the inner cover 110, and reduce the generation of condensed water on the lower surface of the inner cover 110. In other optional embodiments, the diverter rib 121 can also be formed on the upper surface of the inner cover 110, and the diverter rib 121 can also be an independent component. In other optional embodiments, the cover plate 120 and the steam valve 130 may not be provided, the pot cover 100 may have an upper cover 140 , and the steam channel 150 may also be formed between the upper cover 140 and the inner cover 110 .
[0039] like Figure 3 , 5 As shown, the cover plate 120 has a downwardly protruding outer rib 126, an inner rib 127 and a separating rib 122, the first channel 151 is located between the outer rib 126 and the separating rib 122, the second channel 152 is located between the inner rib 127 and the separating rib 122, and the diverter rib 121 extends from the inner rib 127 to the outer rib 126. The outer rib 126, the inner rib 127 and the separating rib 122 are easy to process, and the first channel 151 and the second channel 152 can be formed after the cover plate 120 and the inner cover 110 are assembled, and the structure is relatively simple. The outer rib 126, the inner rib 127 and the separating rib 122 of this embodiment are integrally formed on the cover plate 120. In other optional embodiments, the outer rib 126, the inner rib 127 and the separating rib 122 can also be formed on the upper surface of the inner cover 110, and the outer rib 126, the inner rib 127 and the separating rib 122 can also be independent components.
[0040] like Figure 3 As shown in FIG. 5 , the gas outlet 123 includes a first outlet 124 and a second outlet 125 corresponding to the first channel 151 and the second channel 152, respectively. The distance between the first outlet 124 and the second outlet 125 is smaller than the radius of the cover plate 120. The smaller distance between the first outlet 124 and the second outlet 125 is conducive to the convergence of steam from the two outlets through the smaller steam valve 130. In other optional embodiments, such as Figure 6 As shown, the air outlet 123 may also have only one outlet, and the first channel 151 and the second channel 152 may share one outlet.
[0041] like Figure 1 -4, the bottom wall area of the steam channel 150 is greater than 50% of the upper surface area of the inner cover 110. In this embodiment, the sum of the bottom wall areas of the first channel 151 and the second channel 152 is greater than 50% of the upper surface area of the inner cover 110. The larger upper surface of the inner cover 110 can be directly heated by the steam in the first channel 151 and the second channel 152, which can more comprehensively and directly increase the temperature of the upper surface of the inner cover 110, reduce the occurrence of local low temperature in the inner cover 110, and reduce the possibility of local condensation water on the lower surface of the inner cover 110. In this embodiment, the outer rib 126 is located at the edge of the cover plate 120, and the cover plate 120 is used to enclose the steam channel 150 to the greatest extent. The bottom wall area of the steam channel 150 can reach more than 80% of the upper surface area of the inner cover 110.
[0042] Furthermore, the inner cover 110 is provided with a water collecting member (not shown in the figure), and the water collecting member has a receiving cavity with an opening facing upward, so that the condensed water flowing out of the air inlet falls into the receiving cavity, thereby preventing the condensed water in the steam channel 150 from flowing back into the cooking cavity 210 of the pot body 200.
