Since the rice draining electric rice cooker cannot realize complete separation of rice and rice soup during the rice steaming stage, the rice at the bottom of the rice steaming pot is soaked by the rice soup foam, causing the upper layer of the cooked rice to be loose, and the lower layer to be still wet, which cannot achieve the effect of high-quality rice draining. UTILITY MODEL CONTENTS
[0003] The utility model aims at solving the deficiency of the existing rice draining electric rice cooker and provides a rice draining electric rice cooker adopting an air rice soup volume displacement structure, and the technical scheme is as follows:
[0004] See Figures 3a to 3f An air rice soup volume displacement structure includes a cavity wall arranged in a ring shape and a cavity top arranged at the upper portion of the cavity wall, and the cavity wall and the cavity top jointly enclose an air rice soup volume displacement cavity. The cavity top is provided with a plurality of steam impact pipes, and the number of the steam impact pipes is zero, one or more.
[0005] If the steam impact pipes are arranged, the upper pipe opening of the steam impact pipes is sealingly connected to the cavity top or a suitable position below the upper pipe opening, and the lower pipe opening of the steam impact pipes is suspended in the air rice soup volume displacement cavity.
[0006] The length of the steam impact pipes in the air rice soup volume displacement cavity is slightly smaller than the net depth of the air rice soup volume displacement cavity, and the cross section of the steam impact pipes is one or a combination of more than one of a circular shape, an elliptical shape, a triangular shape, a waist shape and a rectangular shape.
[0007] The cross section of the air rice soup volume displacement cavity is one or a combination of more than one of a circular shape, an elliptical shape, a triangular shape, a waist shape and a rectangular shape.
[0008] A water passing structure between the bottom of the rice cooking pot and the cavity wall of the air rice soup volume displacement cavity is arranged at the bottom of the cavity wall of the air rice soup volume displacement cavity.
[0009] The water passing structure includes a plurality of water passing openings or water passing holes arranged at the lower periphery of the cavity wall, or a plurality of supporting legs arranged at the lower periphery of the cavity wall.
[0010] The edge length of the lower opening of the cavity wall of the air rice soup volume replacement cavity is the same as or different from the edge length of the top opening of the cavity; the edge length of the upper tube opening of the steam impact tube sealingly connected with the top opening of the cavity is the same as or different from the edge length of the lower tube opening suspended in the cavity.
[0011] Referring to Figure 3g , the air rice soup volume replacement cavity and the rice steaming basket can also be an integrated structure. When the air rice soup volume replacement cavity and the rice steaming basket are an integrated structure and the rice steaming basket is suspended by the mouth edge thereof in contact with the mouth edge of the rice cooking pot, the lower edge of the wall of the air rice soup volume replacement cavity is suspended in the space near the bottom of the rice cooking pot, and the water passing structure of the lower edge of the wall of the air rice soup volume replacement cavity does not need to be provided.
[0012] The air rice soup volume replacement structure is made of a metal plate material punched or welded, or is integrally formed by plastic material injection molding, and the steam impact tube is made of stainless steel or other hard materials.
[0013] The air rice soup volume replacement structure in the present application is applied as follows:
[0014] Referring to Figure 4a , Figure 4b , a rice draining electric rice cooker mainly includes a pot body, an electric heating device, a temperature sensor, and a control device. The rice cooking pot and the rice steaming basket are sequentially embedded in the pot body. The air rice soup volume replacement cavity with the above structure or the rice steaming basket with an integrated structure with the air rice soup volume replacement cavity is placed between the bottom of the rice cooking pot and the bottom of the rice steaming basket.
[0015] The rice steaming basket is suspended by the mouth edge thereof in contact with the mouth edge of the rice cooking pot, or the air rice soup volume replacement structure directly supports the rice steaming basket in the rice cooking pot.
[0016] A fan for forcibly and quickly cooling the electric heating device is arranged at the bottom of the pot body.
[0017] The electric heating device is a heating body that generates heat through the effect of electric current, or a high-frequency induction coil that inductively heats the bottom of the rice cooking pot.
[0018] In combination with the above structure, the purpose of the present application is to realize the following method for cooking rice draining in an electric rice cooker:
[0019] Preparation for cooking: referring to Figure 5a , the air rice soup volume replacement cavity is first placed in the rice cooking pot of the electric rice cooker, the rice steaming basket is then placed above the air rice soup volume replacement cavity, and then clean water is added so that the water surface slightly overflows the upper surface of the rice layer in the rice steaming basket. At this time, because the water in the rice cooking pot forms a sealing effect on the lower edge of the cavity wall of the air rice soup volume replacement cavity or the lower tube opening with the steam impact tube, a certain volume of air is retained in the cavity of the air rice soup volume replacement cavity.
[0020] Boiling water phase: the rice cooker is started, the control system controls the electric heating device to be powered continuously or intermittently until the water in the rice cooking pot is boiled, and the temperature sensor of the rice cooker sends a water boiling signal to the control system, and the control system starts timing of the rice cooking phase.
[0021] Rice cooking phase: refer to Figure 5b , the boiling water cooks the rice in the rice steaming basket, and a large amount of steam generated at the bottom of the rice cooking pot gradually dilutes and replaces the original air in the cavity, until the volume of the original air in the replacement cavity is almost completely replaced by saturated steam, at which time the saturated steam remaining in the replacement cavity is the same volume as the original air.
[0022] Cooling phase: the rice cooking timing of the control system ends, and the rice is cooked to about 8 minutes, the water in the rice cooking pot becomes rice soup, at which time the control system stops or reduces power supply to the electric heating device, the rice soup in the rice cooking pot stops boiling and gradually cools down, when the temperature of the rice soup in the rice cooking pot is slightly lower than the boiling point of water, the saturated steam in the air rice soup volume replacement cavity gradually condenses into water, and the volume of the saturated steam is gradually replaced by the rice soup. At the same time that the control system stops or reduces power supply to the electric heating device, the control system starts timing of the rice draining phase.
[0023] Rice draining phase: refer to Figure 5c , as the rice draining time continues, the volume of saturated steam is gradually replaced by the volume of rice soup, until the volume of saturated steam in the air rice soup volume replacement cavity is almost completely replaced by the rice soup condensed into water, at which time the air rice soup replacement cavity retains rice soup, because the same volume of rice soup as the original air enters the cavity of the replacement cavity, causing the water surface of the rice soup in the rice cooking pot to drop significantly, to below the bottom of the rice steaming basket, realizing complete separation of the rice soup and the rice.
[0024] Rice steaming phase: the rice draining timing of the control system ends, the control system again or continues to supply small power to the electric heating device without causing the rice soup to boil violently, and the steam in the rice cooking pot continues to cook the rice in the rice steaming basket, and the control system starts timing of the rice steaming phase.
[0025] Cooking is completed: the rice steaming timing of the control system ends, the rice in the rice steaming basket is completely cooked, the buzzer of the control system emits a ringing sound, and the rice cooker completes the preparation of the rice draining rice, and the upper and lower layers of the rice draining rice are loose.
[0026] Because the air rice soup volume displacement cavity is placed between the bottom of the rice cooking pot and the bottom of the rice steaming basket, the control system controls the power supply, power-off and power adjustment of the electric heating device at each time period, so that the air volume in the air rice soup volume displacement cavity and the saturated steam volume are replaced, and the saturated steam volume and the rice soup volume are replaced, forming complete separation of the rice soup and the rice during the rice steaming stage.
[0027] Further explanation:
[0028] Firstly, the rice cooking timing can be set to three or more options at S20, and the user can select at the preparation stage S10. The three different times correspond to three different textures of the drained rice, such as slightly harder texture, the corresponding rice cooking timing is slightly shorter, moderate texture, the corresponding rice cooking timing is in the middle, and slightly softer texture, the corresponding rice cooking timing is slightly longer.
[0029] Secondly, referring to Figure 9 A fan can be provided at the bottom of the electric rice cooker, and the fan is started at the same time as the start of the rice draining stage S50. The fan blows cold air outside the electric rice cooker to the bottom of the electric heating device and the rice cooking pot, assisting the boiling rice soup in the rice cooking pot to cool down, thereby speeding up the rice draining process, shortening the time of the rice draining stage, and making the looseness of the upper layer of the cooked drained rice and the bottom layer of the cooked drained rice more consistent.
[0030] Thirdly, the function of the steam impact pipe is to collect the steam in the displacement cavity and spray it upward, forming an impact type rice cooking on the rice in the rice steaming basket, so that more rice starch is washed and dissolved into the rice soup, and the glycemic index of the cooked drained rice is also reduced by one level.
[0031] The main working mechanism of the method of using air rice soup volume displacement to cook drained rice is:
[0032] Referring to Figure 5a Firstly, the lower edge of the cavity wall of the displacement cavity and the lower edge of the steam impact pipe are sealed by the water added in the rice cooking pot, and a certain amount of air is pre-stored in the cavity space of the displacement cavity. This amount of air has pre-occupied the same volume space of water in the rice cooking pot, which lays the foundation for the rice soup in the later rice draining stage to enter the displacement cavity, so that the rice soup water surface drops significantly below the bottom of the rice steaming basket.
[0033] Referring to Figure 5b, second, the water in the rice pot is boiled to form a shock type of cooking rice, while the air in the displacement cavity is gradually diluted by the saturated steam generated by the vigorous boiling, and before the end of the cooking stage, the volume of saturated steam in the displacement cavity will almost completely replace the volume of air, forming a further cushion for the volume replacement of the rice soup and saturated steam in the next step of the rice draining stage.
[0034] Reference Figure 5c , three is to use the physical law that saturated steam will gradually condense into water when its temperature is lower than the boiling point of water, and the air rice soup volume displacement cavity gradually replaces the previous saturated steam, because the rice soup fills the cavity space of the air rice soup displacement cavity, eventually causing the water level of the rice soup to drop significantly, reaching the bottom of the rice steamer, and achieving the complete separation of rice and rice soup.
[0035] Four is to continue or again give the electric heating device with small power heating so that the rice soup does not boil vigorously, to continue to steam the rice with weak steam.
[0036] Brief description of working mechanism: it is to use the space in the air rice soup volume displacement cavity between the bottom of the rice pot and the bottom of the rice steamer, and to use the power on and off and power control of the electric heating device in each stage of cooking, so as to realize the twice equal volume replacement between air and saturated steam and between saturated steam and rice soup in the air rice soup volume displacement cavity, and finally replace the original air volume in the displacement cavity with the same volume of rice soup.
[0037] The beneficial effects of the present application are:
[0038] 1. The lower layer of rice made by the existing rice draining electric rice cooker is not loose enough.
[0039] 2. The rice draining electric rice cooker with air rice soup volume displacement cavity has simple structure, without special rice soup valve, rice soup channel and external rice soup box, etc. complex structure, which can greatly reduce the production cost and the complexity of use.
[0040] 3. Only the power on and off and power control of the electric heating device in each stage of cooking makes the complete separation of rice soup and rice, without the need for rice soup electromagnetic valve and complex mechanism such as lifting the position of the rice steamer, which improves the reliability of the rice draining electric rice cooker.
[0041] 4. The steam impact pipe collects the steam generated at the bottom of the rice pot together to form a strong upward steam flow, which forms a strong impact type of cooking rice in the rice steamer and the rice soup, so that more starch on the surface of the rice is washed and dissolved into the rice soup, and the glycemic index of the rice made by the rice draining electric rice cooker is reduced by one level.

[0056] Specific embodiment one of air rice soup volume displacement structure:
[0057] Specific embodiment one, see Figure 3a As shown in the figure, air rice soup volume displacement structure includes annularly arranged cavity wall 1-1 and cavity top 1-2 arranged on the upper part of cavity wall, and cavity wall 1-1 and cavity top 1-2 jointly enclose air rice soup volume displacement cavity 1, cavity top 1-2 is not provided with steam impact pipe, and the bottom of cavity wall 1-1 of air rice soup volume displacement cavity 1 is provided with water pass gap 1-3 communicating air rice soup volume displacement cavity 1.
[0058] Specific embodiment two, see Figure 3b As shown in the figure, a steam impact pipe is arranged on cavity top 1-2, and the upper pipe opening of steam impact pipe 1-4 is sealingly connected with cavity top 1-2, and the lower pipe opening of steam impact pipe 1-4 is suspended in the cavity of air rice soup volume displacement cavity 1.
[0059] Specific embodiment three, see Figure 3c As shown in the figure, the diameter of displacement cavity cavity wall lower edge is greater than the diameter of cavity top, the diameter of lower pipe opening of steam impact pipe 1-4 is greater than the diameter of upper pipe opening, and water pass structure 1-3 of displacement cavity cavity wall lower edge periphery is formed by three support feet.
[0060] Specific embodiment four, see Figure 3d As shown in the figure, the number of steam impact pipes is three, and the water pass structure is a through hole formed on the lower edge of displacement cavity wall.
[0061] Specific embodiment five, see Figure 3eAs shown, no steam impact pipe is installed on the top 1-2 of the cavity. The water passage structure around the lower edge of the cavity wall of the replacement cavity is formed by three elongated water passage holes 1-3 opened near the lower edge.
[0062] See Specific Implementation Example Six. Figure 3f As shown, the top of the displacement chamber is connected to the chamber wall in an arc shape, and the upper opening of the steam impact pipe is slightly higher than the upper surface of the displacement chamber.
[0063] The features of the above six embodiments can be combined in different ways to form more specific embodiments, which will not be elaborated here.
[0064] Example 1 of the rice cooker with drained rice:
[0065] like Figure 6 As shown: The main structure of the rice cooker includes a pot body 10, an air-rice-water replacement chamber 1, a cooking pot 2, a steaming basket 3, a heating plate 4, a control system 5, a bottom temperature sensor 6-1, a lid temperature sensor 6-2, an operation panel 7, and a lid 8. An air-rice-water volume replacement structure is placed between the bottom of the cooking pot 2 and the bottom of the steaming basket 3. The air-rice-water replacement chamber structure adopts the following... Figure 3c The steam impact pipe 1-4 has a small upper opening and a large lower opening.
[0066] like Figure 2 As shown, the main rice cooking process in Specific Embodiment 1 is as follows:
[0067] Preparation for cooking: such as Figure 5a As shown, first place the air-rice-water volume replacement chamber in the rice cooker, then place the rice steaming basket above the replacement chamber, and then add water so that the water level slightly covers the upper surface of the rice layer in the rice steaming basket.
[0068] Heating stage: Start the rice cooker, select the rice draining function, and the control system controls the heating element to be continuously or intermittently powered until the water in the rice cooker boils violently. At the same time, the control system starts the timer for the rice cooking stage.
[0069] Rice cooking stage: Water vapor impacts the rice in the steaming basket through the steam impact pipe to cook the rice in an impact manner. At the same time, the water vapor gradually dilutes and replaces the air originally present in the cavity until the volume of the original air is almost completely replaced by the volume of saturated steam.
[0070] Cooling phase: such as Figure 5b As shown, the rice cooking timer in the control system ends, and the rice is about 80% cooked. The control system stops supplying power to the heating element, and the rice water in the rice cooker stops boiling and gradually cools down and begins to condense into water. At the same time, the control system starts timing the rice draining stage.
[0071] Rice draining stage: such as Figure 5cAs shown, with the extension of the draining time, the volume of the air-rice soup replacing the saturated steam in the replacement cavity is almost entirely replaced by the condensed water. At this time, the air-rice soup replacement cavity retains the same volume of rice soup as the original air, and the rice soup surface is lowered below the bottom of the rice steaming basket, realizing the complete separation of the rice soup and the rice.
[0072] Steaming stage: the control system's draining timing time ends, and the control system again applies small power to the electric heating device. The steam in the rice cooker cooks the rice in the rice steaming basket, and at the same time, the control system starts the timing of the steaming stage.
[0073] End of cooking: the control system's steaming timing time ends, and the rice in the rice steaming basket is completely cooked. The control system's buzzer emits a ringing sound, and the electric rice cooker completes the cooking of the drained rice.
[0074] Further selection can be made among the three mouthfeel options of the drained rice during the preparation stage. The three mouthfeels correspond to the three settings of the cooking time. The selection of hard mouthfeel corresponds to a slightly shorter cooking time, the selection of moderate mouthfeel corresponds to a cooking time suitable for general mouthfeel, and the selection of soft mouthfeel corresponds to a slightly longer cooking time.
[0075] The steam impact pipe not only plays a sealing and isolating role on the inside and outside of the cavity top of the replacement cavity, but also forms a powerful steam flow upward due to the steam in the replacement cavity being almost concentrated upward through the steam impact pipe. The rice and rice soup in the rice steaming basket are strongly impacted. Since the rice and rice soup near the steam impact pipe port are continuously impacted upward by the powerful steam flow, the middle convex-shaped rice soup formed by the impact can only flow back downward along the positions of the rice steaming basket that are not close to the steam impact pipe port. This cyclic impact cooking makes more starch on the surface of the rice be washed and dissolved into the rice soup, ultimately making the glycemic index of the drained rice decrease by one level.
[0076] In this embodiment, as shown in Figure 4a , the air-rice soup volume replacement structure is in a separate structure from the rice steaming basket. In fact, as shown in Figure 4b , the cavity top 1-2 of the air-rice soup volume replacement cavity and the basket bottom of the rice steaming basket 3 can be combined into one, forming an integrated structure of the air-rice soup volume replacement cavity 1 and the rice steaming basket 3.
[0077] Specific embodiment two of the drained rice electric rice cooker:
[0078] As shown in Figure 7 : The differences between embodiment two and embodiment one are that there is no steam impact pipe in the air-rice soup replacement cavity, and an electric heating ring 4-1 is added to heat the outer wall near the bottom of the rice cooker.
[0079] The main structure includes a pot body 10, an air-rice-water replacement chamber 1, a rice cooker 2, a rice steamer basket 3, a bottom heating device 4, an electric heating coil 4-1, a control system 5, a bottom temperature sensor 6-1, a lid temperature sensor 6-2, an operation panel 7, and a lid 8.
[0080] The main cooking process of Specific Embodiment Two is basically the same as that of Embodiment One. The only difference is that during the steaming stage, the electric heating device 4 at the bottom of the pot is not powered, but the electric heating coil 4-1 located on the lower part of the outer periphery of the rice cooker is powered instead. In this way, the rice can be steamed with a larger power during the steaming stage, and the stronger steam will make the rice taste better.
[0081] Specific implementation method three for the rice cooker with drained rice:
[0082] like Figure 8 As shown: The difference between Embodiment 3 and Embodiment 1 is that, firstly, the air-rice-water volume replacement chamber and the rice steaming basket are integrated structures, and the edge of the rice steaming basket and the edge of the rice cooker form a contact suspension, so there is no need to set a water passage structure on the lower edge of the replacement chamber wall; secondly, the electric heating plate 4 at the bottom of the pot is replaced with an electromagnetic induction coil 4-2, which uses electromagnetic induction to heat the rice cooker. Its advantage is that the electromagnetic induction heating method has almost no thermal inertia, which greatly speeds up the process of draining rice.
[0083] The main cooking process of Specific Embodiment 3 is basically the same as that of Embodiment 1. The only difference is that the time for draining the rice can be greatly shortened, so that the looseness of the top layer of rice and the bottom layer of rice in the cooked drained rice is more consistent.
[0084] Example 4 of the rice cooker with drained rice:
[0085] like Figure 9 As shown: The difference between Embodiment 4 and Embodiment 1 is that, firstly, the upper and lower openings of the steam impact pipe are the same, and secondly, a fan 9 is installed at the bottom of the rice cooker body 10. The fan 9 starts to operate during the rice draining stage, and its function is to accelerate the heat dissipation and cooling of the boiling rice water in the rice cooker, thereby speeding up the process of rice draining.
[0086] The main cooking process of Specific Embodiment Four is basically the same as that of Embodiment One. The only difference is that the timing of the rice draining stage can be significantly reduced, which, like in Embodiment Three, makes the looseness of the top layer of rice and the bottom layer of rice more consistent.
[0087] It should be noted that the description of the utility model and its drawings give the preferred embodiments of the utility model, and are not limited to the embodiments described in the description, these embodiments are not as additional limitation to the content of the utility model, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive. Furthermore, the above technical features continue to combine, form various embodiments not listed above, which are considered as the range of the description of the utility model; further, for those skilled in the art, the above description can be improved or transformed, and all these improvements and transformations should belong to the protection scope of the utility model claims.
