Abstract
Description
Technical Field
[0001] The invention belongs to the field of kitchen utensil manufacturing, in particular to a rice draining electric rice cooker capable of completely separating rice soup from rice. Background Art
[0002] See Figure 1 The structure of a rice draining rice cooker is popular in the market. The reference numerals include: 100 is a pot body, 200 is a rice cooking pot, 300 is a rice steaming pot, 400 is an electric heating plate, 500 is rice soup, 600 is rice soup foam, and 700 is rice. Since the rice draining rice cooker cannot achieve 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, resulting in the upper layer of the cooked rice being loose and the lower layer still being wet, and the effect of high-quality rice draining cannot be achieved. Summary of the invention
[0003] The object of the present invention is to solve the shortcomings of the existing drain rice electric cooker and provide a drain rice electric cooker in which rice soup and rice are completely separated. The technical scheme is as follows: See also Figure 2 , Figures 3a to 3j A rice draining electric rice cooker with rice soup and rice completely separated comprises a pot body, a pot body lining, a rice cooking pot, a steaming grid, an electric heating device, a control system and a temperature sensor. A grid sealing ring is arranged at any height of the bottom edge or side wall of the steaming grid, a pot sealing ring is arranged at a position of the side wall of the rice cooking pot corresponding to the grid sealing ring on the steaming grid, the grid sealing ring of the steaming grid is tightly fitted with the pot sealing ring of the rice cooking pot to form a closed structure, and the closed structure makes the lower space of the rice cooking pot form a relatively closed water vapor space, and a plurality of grid holes with a size smaller than that of rice grains are arranged on the bottom of the steaming grid.
[0004] Ten typical forms of closed structures are listed below: See also Figure 3a A grid sealing ring is formed at the portion where the side wall of the steaming grid is connected to the grid bottom of the steaming grid, the portion where the side wall of the rice cooking pot corresponds to the grid sealing ring on the steaming grid is contracted inwardly to form a lower side wall with a slightly smaller diameter, and a pot sealing ring is formed at the transition portion between the upper side wall and the lower side wall of the rice cooking pot, and the grid sealing ring on the steaming grid and the pot sealing ring on the rice cooking pot are tightly fitted to form a closed structure.
[0005] See also Figure 3b A grid sealing ring is still provided at the position where the side wall of the steaming grid is connected to the grid bottom of the steaming grid, and a convex ring with a slightly reduced diameter is provided at the position where the side wall of the rice cooking pot corresponds to the grid sealing ring on the steaming grid to form a pot sealing ring. The grid sealing ring on the steaming grid and the pot sealing ring on the rice cooking pot are tightly fitted to form a closed structure.
[0006] See also Figure 3cA concave groove with a slightly reduced diameter is arranged at a suitable position in the middle of the outer wall of the steaming grid to form an inner concave sealing ring, and a flexible rubber ring is tightly nested on the inner concave sealing ring. The outer surface of the flexible rubber ring is tightly fitted with the inner wall of the rice cooker to form a closed structure.
[0007] See also Figure 3d An upper retaining ring and a lower retaining ring are arranged on the outer wall of the steaming grid, and the upper retaining ring and the lower retaining ring together form a grid sealing ring. A flexible rubber ring is tightly nested between the upper retaining ring and the lower retaining ring. The grid sealing ring forms a closed structure through the tight fit between the outer surface of the flexible rubber ring and the inner wall of the rice cooker.
[0008] See also Figure 3e An outer convex ring with a slightly increased diameter is arranged on the outer wall of the steaming grid to form a grid sealing ring, and an inner convex ring with a slightly reduced diameter is arranged on the side wall of the rice cooking pot corresponding to the outer convex ring to form a pot sealing ring. The grid sealing ring formed by the outer convex ring and the pot sealing ring formed by the inner convex ring are tightly fitted to form a closed structure.
[0009] See also Figure 3f The outer diameter of the side wall of the steaming grid just matches the inner diameter of the side wall of the rice cooking pot, so that the steaming grid can be embedded in the rice cooking pot more tightly, and the close fit between the side wall of the steaming grid and the side wall of the rice cooking pot forms a closed structure.
[0010] See also Figure 3g , so that the outer diameter of the transition part between the side wall of the steaming grid and the bottom of the steaming grid just matches the inner diameter of the transition part between the side wall and the bottom of the spherical bottom rice cooking pot, the transition part of the bottom of the steaming grid forms a grid sealing ring, and the transition part between the side wall and the bottom of the spherical bottom rice cooking pot forms a pot sealing ring, and the grid sealing ring formed by the transition part between the grid bottom and the side wall of the steaming grid and the pot sealing ring formed by the transition part between the side wall and the bottom of the rice cooking pot are closely fitted to form a closed structure.
[0011] See also Figure 3h A lower side wall having the same or different diameter from the side wall is added below the bottom of the steaming grid, the lower edge of the lower side wall forms a grid sealing ring, the annular portion where the bottom of the rice cooking pot contacts the grid sealing ring forms a pot sealing ring, and the grid sealing ring is directly located on the pot sealing ring to form a closed structure.
[0012] See also Figure 3i The grid sealing ring also includes a sealing ring that can be separated from the rice steaming grid. The inner diameter of the sealing ring coincides with the outer diameter of the side wall of the rice steaming grid close to the grid bottom. The sealing ring is sleeved on the side wall of the rice steaming grid, and then a flexible rubber ring is nested on the sealing ring. The outer skirt of the flexible rubber ring is in close contact with the side wall of the rice cooking pot to form a closed structure.
[0013] See also Figure 3jThe grid sealing ring also includes a grid sealing rubber ring whose inner diameter matches the outer diameter of the side wall of the rice steaming grid near the grid bottom. The grid sealing rubber ring is directly sleeved on the side wall of the rice steaming grid, and the outer skirt of the grid sealing rubber ring is in close contact with the side wall of the rice cooking pot to form a closed structure.
[0014] In fact, the specific closed structure can have many other different forms, which will not be listed one by one.
[0015] The key function of the closed structure is to seal the interval space between the inner wall of the rice cooker and the outer wall of the steaming grid, so that the water vapor and the rising channel in the closed space of the rice cooker are only left with the holes at the bottom of the steaming grid and the water in the rice layer. The holes and the rice layer hinder the rising movement of steam, and a large amount of water vapor is retained in the water vapor space of the rice cooker. The retained water vapor forms steam clusters or steam layers, which displace part of the volume of water in the rice cooker, thereby achieving the effect of raising the boiling water level, laying the preliminary foundation for the complete separation of rice soup and rice in the subsequent rice draining stage.
[0016] The weight of the steaming grid exceeds that of a common steaming grid. The steaming grid has sufficient weight to make the grid sealing ring with a closed structure fit more closely with the pot sealing ring, and has sufficient weight to overcome the upward force exerted on the bottom by the water vapor in the steam space of the rice cooking pot and the violently boiling water.
[0017] The electric heating device may also include an electromagnetic induction coil for induction heating the bottom of the rice cooker.
[0018] A fan for forcibly and rapidly cooling the electric heating device may be arranged at the bottom of the pot body.
[0019] The main working mechanism of the closed structure rice cooker is: See also Figure 4a Before cooking rice, put a steamer in the rice cooker and add clean water. The water level should be about 5 mm or more below the upper surface of the rice. The water level should be lower than the upper surface of the rice to pave the way for the complete separation of the rice soup and the rice after draining.
[0020] See also Figure 4b During the rice cooking stage, the water in the rice cooker is heated to a violent boiling. Due to the closed structure, the steam can only rise through the limited holes in the bottom of the steaming grid and escape through the gaps between the rice grains and the water in the gaps. A large amount of steam is blocked by the holes in the bottom of the steaming grid and the gaps between the rice grains. Therefore, a large amount of water vapor that has no time to escape will gradually gather into a steam mass or steam layer in the water vapor space of the rice cooker, thereby occupying part of the volume of the water, causing the boiling water surface to be significantly higher than the upper surface of the rice. While the water is boiling violently, the control system starts timing the rice cooking time.
[0021] See also Figure 4c In the rice draining stage, when the rice cooking timer is up and the rice is about 80% cooked, the system stops supplying power to the electric heating device or greatly reduces its heating power. At the same time, the control system starts timing the rice draining stage. When the rice soup in the rice cooker stops boiling violently, the steam group or steam layer gathered in the water vapor space of the rice cooker gradually disappears, the water level of the rice soup drops, and the rice draining stage begins. Since part of the water is absorbed by the rice and part of the water is evaporated, when the rice draining is completed, the water level of the rice soup will significantly drop below the bottom of the rice steaming basket, thus achieving a complete separation of rice and rice soup.
[0022] In the rice steaming stage, after the rice draining stage is over, the rice is steamed again with a smaller heat power and the timing of the rice steaming stage begins. Since the rice soup is only slightly boiling, the steam will not gather in large quantities in the closed space of the rice cooker, and the water level of the rice soup is always lower than the bottom of the rice steaming basket. When the rice steaming time is up, the rice is steamed thoroughly. Since the rice and the rice soup are always completely separated in the rice steaming stage, the bottom layer of the rice will not be moistened by the rice soup and foam, thereby solving the defect that the bottom layer of the drained rice made by the existing draining rice cooker is moist and not loose, and significantly improving the quality of the drained rice.
[0023] Further explanation: First, you can make slight adjustments to the rice cooking timer. For example, if you set the rice cooking timer to be a little shorter, the rice will be a little harder. If you set the rice cooking timer to be a little longer, the rice will be a little softer.
[0024] Second, see Figure 6 The electric heating plate of the rice cooker can be replaced with an electromagnetic induction coil. The electromagnetic induction heating method does not have as great thermal inertia as the electric heating plate. Once the power supply of the electromagnetic induction coil is stopped, the violently boiling rice soup in the rice cooker will quickly cool down, thereby speeding up the draining process and shortening the time of the draining stage, making the looseness of the upper and bottom layers of the cooked drained rice more consistent.
[0025] Third, see Figure 7 A centrifugal fan or axial flow fan can be arranged at the bottom of the rice cooker. The fan can be started at the same time as the rice draining stage begins. The fan blows cold air outside the rice cooker to the electric heating device and the bottom of the rice cooker, thereby enhancing the cooling effect of the boiling rice soup in the rice cooker, thereby accelerating the rice draining process, shortening the time of the rice draining stage, and making the looseness of the bottom layer of the cooked drained rice more consistent with that of the upper layer.
[0026] Brief description of the working mechanism: With the help of the closed structure set between the side wall of the steaming grid and the side wall of the rice cooking pot, the water level of the clean water before cooking can be lower than the upper surface of the rice, which lays the preliminary conditions for the subsequent complete separation of the rice soup and the rice. When the water vapor formed by the violent boiling in the rice cooking pot can only pass through the holes at the bottom of the steaming grid and pass through the rice layer, a large amount of water vapor is retained in the closed space of the rice cooking pot and gathered into steam clusters or steam layers. The steam clusters or steam layers occupy part of the spatial volume of the cooking water, so that the water level in the rice cooking pot is raised. The raised boiling water level obviously exceeds the upper surface of the rice. The boiling water level in the rice cooking stage is additionally raised to a certain height, which becomes the rice soup level after draining the rice and drops to below the bottom of the steaming basket, forming a continuous preparation for the complete separation of the rice soup and the rice. The beneficial effects of the present invention are:
[0027] 1. The defect that the lower layer of drained rice made by the existing drained rice electric rice cooker is not loose enough is solved.
[0028] 2. There is no need to set up a special rice soup valve, rice soup channel and external rice soup box, nor is there any need to set up complex structures such as a special rice steaming basket lifting device, or even to add other additional auxiliary devices, which can significantly reduce the production cost of the rice cooker.
[0029] 3. The power supply of the electric heating device is only turned on and off and the power is controlled at each stage of cooking, so that the rice soup and the rice are completely separated. Since there is no complex mechanism such as the rice soup solenoid valve and the rice steaming grid position lifting, the reliability of the rice cooker is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Specific embodiment 1
[0042] like Figure 5 As shown: this embodiment includes a pot body 10, a rice cooker 2, a steaming grid 3, an electric heating plate 4, a control system 5, a pot bottom temperature sensor 6-1, a pot cover temperature sensor 6-2, an operation panel 7 and a pot cover 8.
[0043] The enclosed structure of this embodiment adopts the Figure 3aIn the form of, that is, the closing structure is located at the connecting part between the bottom and the side wall of the steaming grid, and a flexible rubber ring can also be used to enhance the closing performance.
[0044] The main cooking process of the specific embodiment is as follows: See also Figure 4a , prepare to cook rice, put the steaming rack in the rice cooker to make the closed structure tightly combined, then add clean water, the water level should be 5-15mm lower than the upper surface of the rice.
[0045] See also Figure 4b During the rice cooking stage, the water in the rice cooker is heated to a violent boil, and the level of the boiling water rises to a level significantly higher than the upper surface of the rice. While the water is boiling violently, the control system starts timing the rice cooking time.
[0046] See also Figure 4c In the rice draining stage, the rice cooking timer is up and the rice is cooked to about 80% done. The system stops supplying power to the electric heating device or greatly reduces the heating power. At the same time, the control system starts timing the rice draining stage. When the rice soup in the rice cooker stops boiling violently and the water level of the rice soup drops significantly below the bottom of the rice steaming basket, the rice and the rice soup are completely separated.
[0047] During the rice steaming stage, after the rice draining stage is over, the electric heating plate is powered with a smaller thermal power, and the steam generated by the rice soup steams the rice until it is cooked, and the cooking is completed.
[0048] Since the rice and the rice soup are completely separated during the rice steaming stage, the bottom layer of the rice will not be moistened by the rice soup and the foam, thereby solving the defect that the bottom layer of the drained rice made by the existing drained rice cooker is not moist and loose enough, and significantly improving the quality of the drained rice. Specific embodiment 2
[0049] like Figure 6 As shown: The difference between this embodiment and the first embodiment is that the rice cooker of this embodiment has a spherical bottom, so the attached Figure 3g The first is a closed structure of the form, and the second is to replace the electric heating plate 4 at the bottom of the pot with an electromagnetic induction coil 4-1, and use electromagnetic induction to heat the rice cooker. The advantage is that the electromagnetic induction heating method has almost no thermal inertia, which greatly accelerates the process of the rice draining stage.
[0050] The main rice cooking process of this embodiment is basically the same as that of the first embodiment, the only difference is that the time of the rice draining stage can be greatly shortened, so that the looseness of the bottom layer of rice and the upper layer of rice in the cooked drained rice is more consistent. Specific embodiment three
[0051] like Figure 7 As shown: The difference between this embodiment and the first embodiment is that the attached Figure 3cThe second is a closed structure of the form, and a fan 9 is arranged in the lower space of the rice cooker body. The fan 9 starts to run in the rice draining stage, and its function is to accelerate the heat dissipation and cooling of the boiling rice soup in the rice cooker, thereby accelerating the process of the rice draining stage.
[0052] The main cooking process of this specific embodiment is basically the same as that of the first embodiment, with the only difference being that the timing time of the draining rice stage can be greatly reduced, so that the looseness of the drained rice in the bottom layer and the drained rice in the upper layer is more consistent. Specific embodiment 4
[0053] like Figure 8 As shown: The only difference between this embodiment and the first embodiment is that the enclosed structure adopts the attached Figure 3j The invention is in the form of a grid sealing rubber ring which can be separated from the rice steaming grid.
[0054] The main cooking process of this specific embodiment is basically the same as that of embodiment 1 and will not be described in detail here.
