Description

[0001] The invention belongs to the field of kitchen utensil manufacturing, in particular to a water level lifting type drained rice cooking method and a drained rice electric rice cooker. Background Art

[0002] See Figure 1 This is a relatively popular low-sugar rice cooker structure on the market. The reference numerals include: 100 is a pot body, 200 is a rice cooker, 300 is a rice steaming basket, 400 is a heating plate, 500 is rice soup, 600 is rice soup foam, and 700 is rice. The biggest drawback of this low-sugar rice cooker is that the rice and the rice soup cannot be completely separated during the rice steaming stage, so that the rice at the bottom of the rice steaming basket is soaked by the rice soup foam, resulting in the upper layer of the cooked rice being loose, while the lower layer is still wet, and the effect of high-quality rice draining cannot be achieved.

[0003] There is also a rice draining rice cooker with an independent rice soup bowl on the market. The rice soup bowl is placed at the bottom of the rice cooker in the form of a drawer. Although the rice soup and rice can be completely separated, this rice draining rice cooker has three shortcomings. First, the electric heating plate and the rice cooker are a fixed integrated structure, so water cannot enter the bottom outer surface of the rice cooker, causing inconvenience in cleaning; second, when taking out the flat rice soup box with the drawer at the bottom of the rice cooker, you must be careful, otherwise it is easy to cause the rice soup to spill; third, there must be an electromagnetic valve between the bottom of the rice cooker and the rice soup box to control the rice soup to drain to the rice soup drawer, and its working reliability will be affected to a certain extent.

[0004] There is also a rice draining rice cooker on the market that automatically lifts the rice steaming basket during the rice steaming stage. Although it can also achieve complete separation of rice soup and rice, it has two shortcomings because it uses a moving mechanical lifting mechanism. First, the working reliability of the rice cooker is affected to a certain extent. Second, the manufacturing cost is increased, resulting in a high selling price, which is difficult to promote on a large scale. Summary of the invention

[0005] The purpose of the present invention is to solve the many deficiencies of the existing drained rice electric rice cooker, and provide a water level lifting type drained rice cooking method and a drained rice electric rice cooker technical solution is as follows: The technical solution of the water level lifting type rice cooker is as follows: A rice cooker with a water level lifting chamber structure includes a pot body, an electric heating device, a temperature sensor and a control device. A rice cooker and a rice steaming basket are sequentially embedded in the pot body, and the water level lifting chamber is arranged between the bottom of the rice steaming basket and the bottom of the rice cooker.

[0007] See also Fig. 9 and Fig.10 , or a water level lifting type rice steaming basket filled with rice and integrated with a water level lifting bin is placed in a rice cooker.

[0008] See also Figure 3a , Figure 3b and Figure 3c The water level lifting chamber includes a chamber wall arranged in a ring shape and a chamber roof arranged on the upper part of the chamber wall. The chamber wall and the chamber roof together enclose a water level lifting chamber. The enclosed shape of the chamber wall is one or a combination of a circle, an ellipse, a triangle, a waist shape and a rectangle.

[0009] A plurality of holes are arranged on the silo top or on the silo wall near the silo top. The shape of the holes is one or a combination of circular, elliptical, triangular, waist-shaped and rectangular shapes.

[0010] The water level lifting chamber may also include a plurality of supporting feet or a plurality of water through holes arranged at the lower edge of the side wall.

[0011] See also Figure 4a , Figure 4b and Figure 4c The water level lifting bin or the water level lifting type rice steaming basket forms an integrated structure with the rice steaming basket, the basket bottom of the water level lifting type rice steaming basket and the bin top of the water level lifting bin are combined into one, the bin wall of the water level lifting bin is the downward extension of the side wall of the rice steaming basket, or is a new bin wall enclosed by a plate with a reduced size under the blue bottom.

[0012] See also Figure 5a , Figure 5b , Figure 5d and Figure 5e The lower edge of the warehouse wall of the lifting warehouse is directly located on the bottom of the rice cooker, or is directly located on the bottom of the rice cooker through the supporting feet of the lower edge of the warehouse wall.

[0013] See also Figure 5c The water level lifting type rice steaming basket may also include supporting feet arranged at the lower edge of the water level lifting bin, or may be included in an independently arranged supporting frame, and the water level lifting type rice steaming basket may be supported on the bottom of the rice cooker by the supporting feet or the supporting frame.

[0014] See also Figure 5f The water level lifting type rice steaming basket can also be suspended on the bottom of the rice cooker by the overlap contact between the outer turning edge of the rice steaming basket mouth edge and the rice cooker mouth edge, or by the hanging ears of the rice steaming basket mouth edge and the rice cooker mouth edge forming a suspension and being suspended on the bottom of the rice cooker.

[0015] The support feet and the water level lifting bin or the water level lifting type rice steaming basket are arranged separately to form an independent support frame, the support surface of the independent support frame is in contact with and connected with the water level lifting bin or the water level lifting type rice steaming basket, and the support feet of the independent support frame are directly placed on the bottom of the rice cooker.

[0016] join Figure 8 The electric heating device may also include a high-frequency induction coil for induction heating the bottom of the rice cooker.

[0017] See also Fig.10 , or also includes a fan arranged at the bottom of the pot body to force rapid cooling of the electric heating device.

[0018] The water level lifting and lowering chamber structure is made of metal plates by stamping or welding, or is integrally formed by injection molding of plastic materials.

[0019] The process of cooking rice by water level lifting and lowering method is as follows: See Figure 2 S10: preparing for cooking, putting a rice steaming basket with rice in an integrated structure with a water level lifting bin into the rice cooker, or first putting a water level lifting bin with a separate structure into the rice cooker and then putting an ordinary rice steaming basket with rice in, adding clean water to a specified scale according to the amount of rice, at which time the clean water level is lower than the upper surface of the rice, or can be lower than the bottom of the rice steaming basket.

[0020] S20: The electric rice cooker is started, and the electric heating device is continuously or intermittently powered until the water boils violently, and a certain volume of steam layer is formed in the space in the water level lifting chamber, forcing the water level of the violently boiling water to rise to cover the upper surface of the rice, and the boiling water and the water vapor violently cook the rice in the rice steaming basket, and the timing of the rice cooking stage starts at the same time.

[0021] S30: When the rice cooking timer is up and the rice is cooked to about 80% done, the water becomes rice soup, the power supply of the electric heating device is stopped or the power of the electric heating device is reduced, and the timing of the rice draining stage begins. The rice soup stops boiling violently and the water level of the rice soup begins to drop.

[0022] S40: When the rice draining timing time is up, the water level of the rice soup drops significantly to below the bottom of the rice steaming basket, and the electric heating device is supplied with low power again or continuously, and the timing of the rice steaming stage starts at the same time.

[0023] S50: The rice steaming timer is up, the rice is fully cooked, and the rice cooker has completed the rice cooking with the rice soup and rice completely separated.

[0024] The main working mechanism of the water level lifting type rice cooking method is: First, start preparing by cooking: see Figure 6a, put a rice steaming basket with rice in an integrated structure with a water level lifting bin into the rice cooker, or first put a water level lifting bin with a separate structure into the rice cooker and then put an ordinary rice steaming basket with rice in, add clean water to the specified scale according to the amount of rice, at this time the water level of the clean water is lower than the upper surface of the rice, or can be lower than the bottom of the rice steaming basket.

[0025] The second is to increase the boiling water level: see Figure 6b , select the rice draining function of the rice cooker, start the rice cooker, and supply power continuously or intermittently to the electric heating device until the water in the rice cooker boils violently. The violently boiling water produces a large amount of steam. The large amount of steam that cannot be discharged from the holes on the top of the water level lifting bin in time gathers in the space inside the water level lifting bin, forming a steam layer of a certain volume. This steam layer of a certain volume occupies the space of the water in the rice cooker, forcing the water level of the boiling water to rise.

[0026] The third is intense steam cooking: the violently boiling water after the water level rises causes intense cooking of the rice in the rice steaming basket.

[0027] The fourth is to prevent violent boiling: when the rice is cooked to about 80% done and the water has become rice soup, stop the power supply of the electric heating device or greatly reduce the power of the electric heating device, and the rice soup will gradually stop boiling violently.

[0028] Fifth, the rice water level drops: see Figure 6c As the rice soup stops boiling violently, the steam layer in the water level lifting bin gradually disappears until the water level of the rice soup is significantly lowered to below the bottom of the rice steaming basket, thus completely separating the rice soup from the rice.

[0029] The beneficial effects of the present invention are: 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.

[0030] 2. The rice cooker using the cooking method of the present invention has a simple structure and does not require a special rice soup valve, a rice soup channel, an external rice soup box and other complex structures, which can greatly reduce production costs and complexity of use.

[0031] 3. The cooking method of the present invention only requires turning on and off the power supply of the electric heating device and controlling the power at each stage to completely separate the rice soup from the rice. There is no need for complex mechanisms such as a rice soup solenoid valve and a rice steaming basket position lift, thereby improving the reliability of the rice cooker.

[0032] 4. The glycemic index of the drained rice prepared by the cooking method of the present invention will be further reduced, making it more suitable for people with high blood sugar levels. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Specific embodiment one:

[0052] like Figure 7 As shown: the main structure includes a pot body 10, a water level lifting chamber 1, a rice cooker 2, an ordinary rice steaming basket 3, an electric heating plate 4, a control circuit 5, a pot bottom temperature sensor 6-1, a pot cover temperature sensor 6-2, an operation panel 7, a pot cover 8 and a pot body 10.

[0053] The pot bottom temperature sensor 6 - 1 is arranged at the center of the heating plate and is in close contact with the bottom of the rice cooking pot 3 .

[0054] The pot cover temperature sensor 6 - 2 is arranged on the pot cover and is located in the upper space of the rice steaming basket 3 .

[0055] The control device 4 is electrically connected to the pot bottom temperature sensor 6 - 1 , the pot cover temperature sensor 6 - 2 and the electric heating plate 4 .

[0056] The control device switches the electric heating plate on and off and adjusts the power according to the program based on the temperature signal sensed by the temperature sensor.

[0057] A hole is arranged on the top 1-2 of the water level lifting bin 1, and the lower edge of the bin wall 1-1 of the water level lifting bin is directly located on the bottom of the rice cooker.

[0058] The main cooking process of specific embodiment one is as follows: Add clean water to the specified scale according to the amount of rice in the rice cooker, put it into the water level lifting warehouse, and put the rice steaming basket 3 filled with rice into the rice cooker 2.

[0059] See also Figure 6a At this time, the water level is lower than the upper surface of the rice, and can even be lower than the bottom of the rice steaming basket.

[0060] Select the rice draining function and choose one of the three options of soft, medium or hard rice according to your preference, then start the rice cooker.

[0061] The electric heating plate is energized intermittently or continuously to heat the rice cooker and boil water.

[0062] The water in the rice cooker is heated to violent boiling, and a large amount of water vapor is formed by the violent boiling water, which gathers in the water level lifting chamber. Since only a small amount of steam can escape upward through the holes in the blue bottom of the rice steaming basket, a large amount of steam that has no time to escape gathers in the space inside the water level lifting chamber to form a steam layer of a certain volume.

[0063] A certain volume of steam layer occupies the space of water of the same volume in the water level lifting bin, causing the water level in the rice cooker and the rice steaming basket to be raised. The boiling water level rises to overflow the upper surface of the rice. At the same time, the violently boiling water cooks the rice in the rice steaming basket violently.

[0064] See also Figure 6b The boiling water level is raised to cover the upper surface of the rice, and the intense boiling impact cooking causes more starch on the surface of the rice to fall off into the rice soup.

[0065] When the water in the rice cooker 2 is heated to violent boiling, the control device starts timing the rice cooking stage according to the signal of boiling water felt by the pot cover temperature sensor.

[0066] As the rice cooking process continues, the rice cooking timing time of the control device is up, the rice is cooked to about 80% done, part of the water is evaporated, and part of the water is absorbed by the cooked rice.

[0067] See also Figure 6c When the rice cooking time is up, the control device stops the power supply to the electric heating plate, or greatly reduces the power supply of the electric heating plate. After a period of time, the rice soup stops boiling violently, and there is no large amount of steam gathering in the space of the water level lifting bin. The steam layer in the upper space of the water level lifting bin disappears, causing the originally raised rice soup water level to drop significantly. In addition, part of the water is absorbed by the rice and evaporated. Therefore, the rice soup water level after the drop will be significantly lower than the bottom of the rice steaming basket, realizing the complete separation of the rice soup and the rice. When the electric heating plate is powered off or powered at a low power, the control device starts timing the rice draining stage.

[0068] When the rice boiling timing of the control device is up, the electric heating device is supplied with a low power which does not cause the rice soup to boil violently, and at the same time, the control device starts timing the rice steaming stage.

[0069] When the timing time of the rice steaming stage is up, the rice in the rice steaming basket is steamed until it is completely cooked, and the control device emits a beep or gives a rice-cooked display. In this embodiment, the rice soup and the rice are completely separated and the rice is cooked. Specific embodiment 2:

[0070] like Figure 8 As shown: The structural differences between this embodiment and the specific embodiment 1 are: first, a water hole (1-5) is provided at the lower edge of the water level lifting chamber wall (1-1), and the lower edge of the chamber wall (1-1) is also directly located on the bottom of the rice cooker; second, the electric heating plate 4 at the bottom of the pot is replaced with an electromagnetic induction coil 4-1.

[0071] The rice cooker is heated by electromagnetic induction. The advantage is that the electromagnetic induction heating method does not have as large thermal inertia as the electric hot plate heating method. The electromagnetic induction heating method greatly speeds up the process of the rice draining stage.

[0072] 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, and the water level of the rice soup drops rapidly, so that the looseness of the upper layer of rice and the bottom layer of rice in the cooked drained rice is more consistent. Specific embodiment three:

[0073] like Fig. 9 As shown: The structural differences between the specific embodiment and the specific embodiment 1 are: first, a water level lifting type rice steaming basket is adopted; second, the lower edge of the warehouse wall of the water level lifting warehouse with an integrated structure of the rice steaming basket is supported by contacting the bottom of the rice cooker through supporting feet.

[0074] The main cooking process of this embodiment is the same as that of the first embodiment and will not be described in detail here. Specific embodiment four:

[0075] like Fig.10 As shown: The structural differences between the specific embodiment and the specific embodiment one are: first, a water level lifting type rice steaming basket is adopted; second, the water level lifting type rice steaming basket is suspended by the edge of the basket and the edge of the rice cooker; third, a cooling fan and an air duct are arranged at the lower part of the rice cooker body. The fan starts to operate during 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 progress of the rice draining stage.

[0076] The main rice cooking process of this embodiment is basically the same as that of the first embodiment, the only difference is that the operation of the fan shortens the time of the rice draining stage, so that the water level of the rice soup drops faster, making the looseness of the upper layer of rice and the bottom layer of rice in the cooked drained rice more consistent.

[0077] It should be noted that the preferred embodiments of the present invention are given in the specification and its drawings, and are not limited to the embodiments described in this specification. These embodiments are not intended to be additional limitations on the content of the present invention. The purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive. In addition, the above-mentioned technical features continue to be combined with each other to form various embodiments not listed above, which are all considered to be within the scope of the present invention; further, for ordinary technicians in this field, they can be improved or transformed according to the above description, and all these improvements and transformations should belong to the scope of protection of the claims attached to the present invention.
