The present invention relates to a technology for improving uneven cooking in rice cookers, particularly in rice cookers for germinated brown rice.

With the recent trend towards health consciousness, brown rice and germinated brown rice have been attracting attention as a staple food to replace white rice. Germinated brown rice is made by germinating brown rice, and has a very high nutritional value compared to white rice. Recently, rice cookers that can grow germinated brown rice and then cook germinated brown rice have also been commercialized. In addition, various improvements have been made to the basic cooking techniques for rice cookers.

For example, Patent Document 1 discloses a brown rice germination/cooking control device for an electric pressure rice cooker that adjusts the operation of the heater, pressure regulator, and automatic steam exhaust device in the brown rice germination process, soaking process, heating process, and steaming process, and controls the heater under specified conditions (specified algorithm) in the brown rice germination process to achieve good brown rice germination and cooking.

Patent Document 2 also discloses a technology that can prevent sticky rice (broth containing dissolved rice ingredients) from boiling over during cooking by devising the shape of the inner pot of a rice cooker. Specifically, the upper end of the inner pot is formed smaller than the maximum diameter of the inner pot, and an upper cylinder (which is cooled by air) is positioned above the flange, thereby suppressing the amount of steam containing sticky rice ingredients.

Japanese Patent No. 3950137 JP 2018-86301 A

Incidentally, in addition to the germinated brown rice mentioned above, enzyme brown rice has also been attracting attention in recent years. This enzyme brown rice is also called "aged brown rice" or "fermented brown rice", and is made by adding red beans and salt to germinated brown rice, cooking it in a pressure cooker or similar, and leaving it to rest (ferment) for about 3 to 10 days using a rice cooker that can keep it warm.

As mentioned above, in addition to the rice cooking technology for germinated brown rice (germination technology), rice cooking technology for rice cookers in general has also made progress. However, if you try to cook brown rice in a rice cooker, for example, there will always be uneven cooking. For example, if you mix white rice and brown rice and cook it, the brown rice, which is larger than the white rice, tends to gather in the center due to the characteristics of the rice cooker, namely heat convection. This uneven cooking is particularly noticeable when trying to cook enzyme brown rice.

As mentioned above, it is possible to cook germinated brown rice well by using the algorithm disclosed in Patent Document 1 or the inner pot shape disclosed in Patent Document 2, but it is difficult to solve the problem of uneven cooking using only the techniques in Patent Documents 1 and 2, and there is still room for improvement.

The present invention was made in consideration of the problems with the conventional technology described above, and its purpose is to provide a rice cooker for germinated brown rice that achieves good rice cooking, suppresses uneven cooking, and is easy to maintain.

In order to solve the above problems, the present invention provides a rice cooker for germinated brown rice,
A rice cooker for germinated brown rice comprising a rice cooker body provided with a lid body having an inner lid, and a rice cooker kettle housed in a housing recess provided in the rice cooker body, wherein when the lid body is closed and the inner lid and the rice cooker kettle are in contact with each other, brown rice is germinated inside the rice cooker kettle to produce germinated brown rice, and the germinated brown rice is then cooked to produce germinated brown rice and the germinated brown rice can be kept warm,
The rice cooking pot has a generally pot-shaped shape with a bottom, and includes a pot inlet portion having an opening at an upper end, a lower end bottom portion located at a lower end opposite the pot inlet portion, and a cylindrical side wall portion provided as a side wall so as to connect the pot inlet portion and the lower end bottom portion.

In addition, the germinated brown rice rice cooker according to the present invention is
The cylindrical side wall portion is characterized in that an upper end of the cylindrical side wall portion has a minimum inner diameter in the rice cooker, and the minimum inner diameter is 15 cm to 25 cm.

In addition, the germinated brown rice rice cooker according to the present invention is
The germinated brown rice cooker has a control unit that controls a germinated brown rice growing process for growing brown rice into germinated brown rice, a rice cooking process for cooking the germinated brown rice obtained in the germinated brown rice growing process, and a warming process for keeping the germinated brown rice obtained in the rice cooking process warm, according to the amount of brown rice inside the rice cooker,
The rice cooker body is provided with a display unit which indicates whether the rice cooker for germinated brown rice is in the germinated brown rice growing process, rice cooking process, or warming process during operation.

The control unit adjusts the internal temperature of the rice cooker to a first temperature or a second temperature during the germinated brown rice growing process, and the first temperature and the second temperature are alternately switched every hour.

In addition, the germinated brown rice rice cooker according to the present invention is
The control unit is configured to preset the number of times rice is cooked in order to notify the user of the time to clean the rice cooker for germinated brown rice,
The display unit is characterized in that it displays the time to clean when the number of cooking operations of the rice cooker for germinated brown rice reaches the number of cooking times.

In addition, the germinated brown rice rice cooker according to the present invention is
The control unit is set with an automatic sterilization and cleaning function that sterilizes and cleans the rice cooker and inner lid using high-pressure steam, and the automatic sterilization and cleaning function can be executed by pressing a cleaning button provided on the display unit.

According to the present invention, the shape of the rice cooker equipped in the germinated brown rice rice cooker is a roughly pot-shaped shape with a bottom, and more specifically, either one of the upper end or the lower end of the cylindrical side wall of the rice cooker is formed as the smallest inner diameter of the rice cooker, and the maximum inner diameter of the cylindrical side wall is at least 2 cm larger than the inner diameter of the upper end and the lower end of the cylindrical side wall, thereby achieving good rice cooking and suppressing uneven cooking.

Furthermore, by providing the germinated brown rice rice cooker (control unit) with a function to display when to clean based on predetermined conditions (number of times cooked rice) and an automatic sterilization and cleaning function, it is expected that the maintenance will be easier than with conventional germinated brown rice rice cookers. As a result, it is expected that the product lifespan and economy of germinated brown rice cookers will be improved.

The germinated brown rice cooker of the present invention will be described below with reference to the drawings, but is not limited to the following examples as long as it does not deviate from the spirit of the present invention. Note that the germinated brown rice cooker of the present invention is also suitable for cooking white rice, porridge, etc., in addition to germinated brown rice.

Figure 1 shows a schematic diagram of a rice cooker for germinated brown rice according to an embodiment of the present invention. In Figure 1, in order to grasp the schematic configuration image of the rice cooker for germinated brown rice 10, for example, uneven parts and curved shapes are omitted from the illustration. The rice cooker for germinated brown rice 10 shown in the figure comprises a rice cooker main body 20 provided with a lid body 24 having an inner lid 22, and a rice cooking pot 30 housed in a housing recess 26 provided in the rice cooker main body 20. In addition, although not shown in Figure 1, the rice cooking pot 30 according to this embodiment is configured to have a distinctive shape.

The rice cooker main body 20 is provided with a control unit 28 that controls the operation of the germinated brown rice rice cooker 10, and a display unit 20a that displays the operation status of the control unit 28 (each process, etc., described below).

The control unit 28 can be, for example, a dedicated control board or MCU. The control unit 28 is provided in an empty space inside the rice cooker main body 20. In FIG. 1, it is provided on the front side of the rice cooker main body 20, but the location is not limited to this, and the control unit 28 may be provided in another empty space in the rice cooker main body 20.

The display unit 20a performs a display function for indicating the operating state of the germinated brown rice rice cooker 10, and also serves as a control command button for the control unit 28. In FIG. 1, the display unit 20a is provided on the top surface of the rice cooker main body 20, but the display unit 20a can also be provided on the side (front) of the rice cooker main body 20, for example. Also, while the rice cooker main body 20 in FIG. 1 is substantially rectangular prism-shaped, it is not limited to this shape and may be another shape.

For example, as shown in FIG. 2, the shape of the rice cooker body 20 can be substantially cylindrical, with the display unit 20a provided on the side (front) of the body. By giving the rice cooker body 20 (and the germinated brown rice rice cooker 10) of this embodiment such a shape, it is expected that the design will be improved compared to conventional products.

The inner lid 22 is provided with a packing 22a. This packing 22a can be removed from the inner lid 22, for example, during cleaning, and is made of a material that contains charcoal (also referred to as charcoal in this specification). By using the packing 22a that contains charcoal in this way, a deodorizing and sterilizing effect can be expected. In particular, a greater effect (deodorizing and sterilizing effect) can be expected compared to conventional products when keeping enzyme brown rice warm (when maturing it).

The operation of the germinated brown rice cooker 10 according to this embodiment will now be described. First, a predetermined amount of brown rice and water is placed in the rice cooker 30, the rice cooker 30 is placed in the storage recess 26, and the lid 24 is closed. This brings the inner lid 22 and the rice cooker 30 into contact with each other (the packing 22a and the upper end of the rice cooker 30 are in tight contact with each other). In this state, when a predetermined operation button (not shown) provided on the display unit 20a is pressed, the germinated brown rice cooker 10 starts operating.

In this embodiment, by closing the lid body 24 and bringing the inner lid 22 into contact with the rice cooker 30, a more precise airtightness can be maintained compared to a typical rice cooker (a typical rice cooker uses a gasket to keep the airtightness, but in this embodiment, the contact between the inner lid 22 and the rice cooker 30 allows the inside of the rice cooker 30 to be kept airtight).

First, the germinated brown rice growing process begins to grow brown rice into germinated brown rice. In this embodiment, the germinated brown rice growing process lasts for about 4 to 6 hours, for example, and the time can be selected at will (or either the 4-hour or 6-hour mode can be selected).

In the germinated brown rice growing process in this embodiment, the internal temperature of the rice cooker 30 can be controlled to switch every hour (control that alternates between two predetermined temperatures). That is, the control unit 28 in this embodiment adjusts the internal temperature of the rice cooker 30 to 30°C (also called the first temperature) or 34°C (also called the second temperature) in the germinated brown rice growing process. The temperature is then alternated between 30°C and 34°C every hour.

For example, if the germinated brown rice growing process takes 4 hours, the first hour can be at 30°C, the first to second hours at 34°C, the second to third hours at 30°C, and the last three to four hours at 34°C. Similarly, if the germinated brown rice growing process takes 6 hours, the first hour can be at 30°C, the first to second hours at 34°C, the second to third hours at 30°C, the third to fourth hours at 34°C, the fourth to fifth hours at 30°C, and the last five to six hours at 34°C.

In this way, in the germinated brown rice growing process according to this embodiment, the internal temperature of the rice cooker 30 is alternately changed between 30°C and 34°C every hour, thereby making it possible to obtain better germinated brown rice than in the past. For example, in the germinated brown rice growing process according to this embodiment, the internal temperature of the rice cooker 30 can be set to a first temperature of 28°C to 32°C and a second temperature of 33°C to 36°C.

Then, the process proceeds to a rice cooking process in which the germinated brown rice obtained in the germinated brown rice growing process is cooked. This rice cooking process is carried out according to a predetermined algorithm that has been set in advance in the control unit 28. In the rice cooking process in this embodiment, for example, it is preferable to cook the germinated brown rice at a maximum pressure of 0.8 to 2 atmospheres and a maximum heating of 100°C to 130°C, and it is particularly preferable to cook the rice at a maximum pressure of 1.8 atmospheres and a maximum heating of 118°C.

Specifically, the control unit 28 adjusts the internal temperature of the rice cooker 30 to 70°C to 118°C during the first half of the rice cooking process (when cooking rice), and adjusts the internal temperature of the rice cooker 30 to 70°C to 100°C during the second half of the rice cooking process (when steaming).

The germinated brown rice obtained in the rice cooking process is then kept warm in a warming process under specified conditions. The duration of this warming process can be set arbitrarily, for example, from a few hours to about 14 days. After this warming process, for example, matured enzyme brown rice can be obtained.

In this way, the control unit 28 appropriately controls the germinated brown rice growing process, the rice cooking process, and the warming process according to the amount of brown rice inside the rice cooker 30, that is, the germinated brown rice cooker 10 of this embodiment mainly performs the germinated brown rice growing process, the rice cooking process, and the warming process, thereby making it possible to obtain good enzyme brown rice (and germinated brown rice).

In this embodiment, the control unit 28 can be given a function of setting the number of cooking times in advance and notifying the user when to clean the germinated brown rice rice cooker 10 according to the set number of cooking times, or more specifically, a function of displaying on the display unit 20a the time to clean the rice cooker 10 according to the set number of cooking times.

The control unit 28 may further be provided with an automatic sterilization and cleaning function that sterilizes and cleans the rice cooker 30 and the inner lid 22 using high-pressure steam, and the automatic sterilization and cleaning function may be executed by pressing a button (e.g., a cleaning button) provided on the display unit 20a.

In the germinated brown rice cooker 10 according to this embodiment, brown rice is germinated (grown) as a preliminary step in the rice cooking process (germinated brown rice growing process). In particular, since the inside of the rice cooking pot 30 during the germinated brown rice growing process is an environment that is prone to bacterial growth, the automatic sterilization and cleaning function in the germinated brown rice cooker 10 is expected to have a high sterilization and cleaning effect.

For example, the control unit 28 can be provided with a function to notify the user when it is time to replace the gasket 22a (for example, a function to display an alarm when the number of cooking times is between 700 and 730, or to notify the user by voice). By providing the control unit 28 with these functions, it is expected that the ease of maintenance will be improved compared to conventional rice cookers for germinated brown rice. As a result, it is also possible to obtain effects such as an improved product lifespan.

Next, the rice cooker 30 according to this embodiment will be described. FIG. 3 shows a schematic cross-sectional view of the rice cooker 30 according to this embodiment. In FIG. 3, in order to easily explain the shape of the rice cooker 30, the uneven shape that an actual rice cooker 30 has is omitted, and the characteristic parts are depicted more dramatically than in reality.

As shown in FIG. 3, the rice cooker 30 includes a pot inlet 32 with an opening at the top, a bottom end 34 located at the bottom end opposite the pot inlet 32, and a cylindrical side wall 36 that serves as a side wall connecting the pot inlet 32 and the bottom end 34.

Specifically, the upper end 36a of the cylindrical side wall portion 36 is connected to the kettle inlet portion 32,
The lower end 36b is connected to the lower end bottom portion 34. In other words, the rice cooking pot 30 as a whole is configured to have a generally bottomed, generally pot-like shape.

The upper end of the pot inlet 32 (the uppermost end position of the rice cooker 30) has a shape that is wider than the maximum inner diameter of the cylindrical side wall 36. In other words, as shown in FIG. 4, the side of the rice cooker 30 in this embodiment (the shape of the inside of the side wall) has an S-line shape.

The pot inlet 32 is provided with a holding portion 38 that serves as a handle for the rice cooker 30. In addition to serving as a handle, the holding portion 38 also serves as a fixing aid for firmly fixing the rice cooker 30 in the storage recess 26 when the rice cooker 30 is stored in the storage recess 26 of the rice cooker body 20.

In this embodiment, the rice cooker 30 is made of iron and is coated with a black diamond material that contains charcoal and iron. By coating the rice cooker 30 in this way, it is more resistant to abrasion and has excellent durability, and is also expected to have an improved thermal conductivity.

The lower end bottom portion 34 is configured to have a smooth curved shape (curved outward). In addition, high-temperature thermal energy (up to approximately 100°C to 150°C) is applied to the lower end bottom portion 34, for example, by a heater (and IH) included in the rice cooker body 20. In this embodiment, the cylindrical side wall portion 36 can also be configured to receive thermal energy from a heater or IH, in addition to the lower end bottom portion 34.

As mentioned above, when cooking germinated brown rice, there is a risk of uneven cooking due to thermal convection. This thermal convection is a phenomenon that is bound to occur due to the characteristics of rice cookers, and while various rice cooking techniques have improved in recent years, no rice cooking technique has been developed that takes this into account. This uneven cooking is particularly noticeable when cooking germinated brown rice (and the enzyme brown rice mentioned above).

Therefore, in this embodiment, the shape of the rice cooker 30 is devised to achieve good rice cooking and prevent uneven cooking. The characteristic shape of the rice cooker 30 according to this embodiment is described in detail below. Note that in this specification, thermal convection refers to vertical convection in which a fluid repeatedly moves up and down due to a temperature difference in the fluid.

Figure 5 shows an enlarged view of the cylindrical side wall of the rice cooker according to this embodiment. As shown in Figure 5, in the rice cooker 30 according to this embodiment, the upper end 36a of the cylindrical side wall 36 is seamlessly connected to the lowest end position of the pot inlet 32, and the lower end 36b of the cylindrical side wall 36 is seamlessly connected to the highest end position of the lower end bottom 34. In other words, the rice cooker 30 is formed as a single unit during manufacturing, for example, using a mold or the like.

As shown in FIG. 5, the cylindrical side wall portion 36 in this embodiment is formed so that either the upper end 36a or the lower end 36b of the cylindrical side wall portion 36 has the smallest inner diameter in the rice cooker 30. The rice cooker 30 is also formed so that the inner diameter of the upper end 36a of the cylindrical side wall portion 36 is smaller than the inner diameter of the opening in the pot inlet portion 32. For example, it is preferable that the inner diameter of the upper end 36a is approximately 1 cm to 4 cm smaller than the inner diameter of the opening in the pot inlet portion 32. In this embodiment, it is preferable that the upper end 36a is formed as the smallest inner diameter in the rice cooker 30. Also, for example, the upper end 36a and the lower end 36b of the cylindrical side wall portion 36 can have the same inner diameter.

In this embodiment, the inner diameter of the upper end 36a is preferably, for example, 15 cm to 25 cm, and it is particularly preferable that the inner diameter of the upper end 36a is 16 cm to 20 cm. Additionally, in this embodiment, the inner diameter of the upper end 36a can be 17 cm to 19 cm. Also, in this embodiment, it is preferable that the thickness of the cylindrical side wall portion 36 is 3 mm to 5 mm.

The cylindrical side wall portion 36 is formed as a side wall that is gently rounded in the outer circumferential direction as a whole, and the maximum inner diameter of the cylindrical side wall portion 36 is located approximately at the center position in the vertical direction of the cylindrical side wall portion 36 (between the upper end 36a and the lower end 36b).

This maximum inner diameter is preferably at least 0.3 cm larger than the inner diameters of both the upper end 36a and the lower end 36b of the cylindrical side wall portion 36, and more preferably 0.5 cm or more or 0.8 cm or more larger than the inner diameters of both the upper end 36a and the lower end 36b, and more preferably 1 cm or more larger than the inner diameters of both the upper end 36a and the lower end 36b. In this embodiment, the maximum inner diameter of the rice cooker 30 can also be 2 cm to 4 cm or more larger than the inner diameters of both the upper end 36a and the lower end 36b of the cylindrical side wall portion 36.

By giving the rice cooker 30 of this embodiment such a characteristic shape, irregularities are created in the thermal convection during cooking (e.g., turbulence is created), which results in significantly reduced uneven cooking.

Figure 6 shows a schematic image of the cooked state (cooked state) of rice in a germinated brown rice rice cooker according to this embodiment and in a general rice cooker. As shown in Figure 6 (a), when enzyme brown rice is cooked in a general rice cooker (or a germinated brown rice rice cooker), the red beans tend to concentrate in the center due to the influence of thermal convection (for example, the interaction between thermal convection and vibrations during cooking), which can result in uneven cooking.

On the other hand, as shown in FIG. 6(b), when enzyme brown rice is cooked in the germinated brown rice cooker 10 according to this embodiment, the characteristic shape of the rice cooker 30 causes irregularities in the thermal convection (or there are no blind spots in the convection and the entire inside of the rice cooker is mixed), so the red beans do not concentrate in the center, and even cooking can be achieved.

In this way, the germinated brown rice rice cooker 10 of the present invention has a rice cooking pot 30 that is roughly pot-shaped with a bottom, and more specifically, either the upper end 36a or the lower end 36b of the cylindrical side wall portion 36 of the rice cooking pot 30 is formed to have the smallest inner diameter of the rice cooking pot 30, and the maximum inner diameter of the cylindrical side wall portion 36 is at least 2 cm larger than the inner diameter of the upper end 36a and the lower end 36b of the cylindrical side wall portion 36, thereby achieving good rice cooking and preventing uneven cooking.

In addition, in this embodiment, a germinated brown rice rice cooker having a germinated brown rice growing process has been described, but the same effect can be obtained by using the rice cooker 30 of the present invention in, for example, a rice cooker that does not have a germinated brown rice growing process or a rice cooker for white rice. Furthermore, in this embodiment, an electric rice cooker (rice cooker for germinated brown rice) has been described, but the same effect can be obtained in, for example, a gas rice cooker (rice cooker for germinated brown rice) or a rice cooker using another heat source.
