Various heaters 12 and 14 are mounted around the outer hook 6 and the inner hook 10, and the operation of the heaters 12 and 14 is controlled by the control device 20. As the control device 20, any control device including a microcomputer can be used.

  Here, the heating plate 12 is installed on the bottom surface of the inner hook 10 so as to heat the inner pot 10, and the outer pot 6 is directly heated and the inner pot 10 is indirectly heated. The side heater 14 is installed in contact with the outer periphery of the heater 6, and a temperature sensor (not shown) is installed around the various heaters 12 and 14, and is controlled by the temperature measured by such a temperature sensor. The apparatus 20 controls the power supplied by the various heaters 12 and 14. Here, a series of rice cooking processes including a dipping process, a heating process, and a steaming process are input to the control device 20 in advance, and a heating time and a heating temperature are input for each process, thereby adjusting the operation of various heaters.

  Furthermore, as shown in FIGS. 2 to 3, the main body 4 not only adjusts rice cooking and heat-retaining operation, but also adjusts so that a separate additional process is further included in a series of rice cooking processes. An operation button 30 that can select a taste is provided, and at the same time, a display unit that displays the cooked and heat-retained state or the taste of rice using various characters or a level bar is provided. The operation button 3 and the display unit are configured to be connected to the control device 20, and input a control signal to the control device 20 or display a control signal output from the control device 20.

Here, the operation button 30 is soaked so that the taste of soft rice can be put out, and an extension process is added, or a heating extension process is added so that the taste of sweet and sticky rice can be put out. Can be configured. For example, various configurations such as a menu button 32, a first time setting button 34a, a second time setting button 34b, a start button 36, a cancel button 38, and the like are possible.
More specifically, the menu button 32 can normally be changed to a rice cooking course selection mode for selecting each rice cooking course such as white rice, brown rice, millet, etc., and can select the taste of soft rice or the taste of sweet rice. Thus, it is possible to change to the rice taste selection mode in which an additional process is input.

In addition, only the second time setting button 34b can be adjusted to bring out the taste of sweet and sticky rice. In addition, by adjusting both the first and second time setting buttons 34a and 34b, the taste of soft rice and the taste of sweet and sticky rice can be obtained simultaneously. Moreover, it is also possible to cook rice having a general taste without adjusting the first and second time setting buttons 34a and 34b.

The start button 36 is soaked by the first and second time setting buttons 34a and 34b so that rice cooking is started by a series of rice cooking processes to which an extension process or a heating extension process is added.
The cancel button 38 allows the control signal input to the control device 20 to be canceled and reset by the menu button 32 and the first and second time setting buttons 34a and 34b.

  The process of determining the rice cooking course and the taste of the rice by the operation button 30 as described above is displayed on the display unit by characters or level bars, but the display unit displays the taste of the rice set by the operation button 30 The liquid crystal display (LIquID CrysTAl DISplAy: 4) is preferably configured, and the liquid crystal display 40 is soft and structured in a level bar shape so that the taste of soft rice and the taste of savory rice can be represented respectively. Although it consists of the taste display part 42 of rice and the taste display part 44 of sweet rice, it can also be comprised so that a rice cooking course may be displayed by a character etc. in the meantime.

  The liquid crystal display 40 can be configured in various forms such as an LED substrate in which a plurality of light emitting diodes are arranged in a row. Accordingly, the taste selection mode of the rice is set by the menu button 32, and the taste of the rice is selected and adjusted by the first and second time setting buttons 34a and 34b. The selection or adjustment state is displayed on the display unit 42 and the level bar of the sweet rice taste display unit 44.

Next, FIG. 4 is a figure which shows the rice cooking process in the electric pressure rice cooker which concerns on this invention. The operation of the electric pressure rice cooker according to the present invention configured as described above will be described with reference to FIG.
First, when the user selects a rice cooking course such as white rice, brown rice, millet, etc. with rice and water added, the control device 20 sets the heating temperature and heating time for each step accordingly.
Usually, each rice cooking course is advanced by a series of rice cooking processes including a standby process A, a soaking process B, a first heating process D, a delay process E, a second heating process F, and a steaming process H. Each step will be described below.

  Here, the standby process A is a process in which power is supplied to the various heaters 12 and 14 during the standby time A while rice and water are put in the inner pot 6, and the soaking process B is performed after the standby process A. A relatively small amount of heat is applied during the soaking time B and the rice is soaked at the soaking temperature T1. In the first heating process D, after the soaking process C, the internal temperature temporarily reaches the heating temperature T2. In this process, a relatively large amount of heat is applied for the first heating time α until it reaches, and the rice is cooked. The delay process E is performed after the first heating process D for various heaters 12 and 14 for overheating and safety reasons. In the second heating step F, after the delay step E, the second heating step F has a larger amount of heat until the internal temperature reaches a secondary higher heating temperature T3. Added during heating time β, rice is cooked completely In the process, the steaming process H is a process in which the power supplied from the various heaters 12 and 14 is steamed for a predetermined time γ after the second heating process F, and the internal temperature of the inner pot 6 is kept constant. It is a process to make the taste of delicious rice.

At the same time, since the rice is cooked through a series of rice cooking processes, the heating time and the heating temperature are input to the control device 20 for each process in advance, whereby the size of the power supplied to the various heaters or the power supply is supplied. It is set to control time and the like.
Next, as described above, after the heating temperature and heating time of each process are determined by the rice cooking course, a separate additional process can be further selected to adjust the taste of the rice.
More specifically, the user uses the menu button 32 to change the taste of the rice to the selection mode, and then uses the first time setting button 34a to add the soaking extension process C to improve the taste of the soft rice. Setting or using the second time setting button 34b, the second heating extension process G can be added to set the taste of sweet and sticky rice. Various tastes of rice can be realized by adding such an additional process to a series of rice cooking processes by a user's operation.

Here, in the dipping extension process C, a relatively small amount of heat is applied after the dipping process B, as in the dipping process B, so that the internal temperature of the inner pot 6 maintains a constant dipping temperature T1, This is a process in which the rice is sufficiently immersed in water. In the second heating extension process G, after the second heating process F, a relatively large amount of heat is applied in the same manner as in the second heating process F. This is a process in which the rice can be burnt to some extent by maintaining the heating temperature T3 at a constant temperature.
While the soaking extension process C and the second heating extension process G proceed, the control device 20 immerses the internal temperature of the inner pot 6 so as to maintain the temperature T1 and the heating temperature T3, respectively. While the two heating extension process G is performed, it is preferable to control so that the power is intermittently supplied to the various heaters 12 and 14.

As described above, the user uses the menu button 32 and the first and second time setting buttons 34a and 34b to immerse in a series of rice cooking processes input in advance to the control device 20 and extend the process C or second. The heating extension process G can be added and the taste of the rice which a user likes can be implement | achieved. Further, the dipping extension process B or the heating extension process G can be set separately and the times x and y can be set, but these can be set sequentially to set the times x and y.
Next, as described above, when a separate additional process is selected for a series of rice cooking processes, the time of the additional process is set to adjust the degree of taste of the rice, thereby a series of rice cooking processes and additional processes. It is done and cooked.

Here, when the user adds the soaking extension process C, the standby process A, the soaking process B, the soaking extension process C, the first heating process D, the delay process E, the second heating process F, and the steaming process H are sequentially performed. For this reason, after the rice is sufficiently soaked in water, the taste of soft rice can be obtained by cooking rice.
When the user adds the second heating extension process G, the standby process A, the dipping process B, the first heating process D, the delay process E, the second heating process F, the second heating extension process G, and the steaming process H are performed. Since it is performed sequentially, the rice can be further heated to produce a savory and sticky rice.
Further, when the user adds the soaking extension process C and the second heating airspace G at the same time, the standby process A, the soaking process B, the soaking extension process C, the first heating process D, the delay process E, the second heating process F, The 2nd heating extension process G and the steaming process H are performed sequentially, and the taste of the rice which is soft and fragrant and can be made simultaneously can also be put out.

Here, the soaking extension process C and the second heating extension process G are selected by the first and second time setting buttons 34a and 34b, and the first setting time x and the second setting time y of each additional process are adjusted and started. Although the rice cooking process including each additional process as described above is sequentially performed by the button 36, the selected rice cooking course is displayed on the liquid crystal display 40 with characters or the like, and the hardness display portion 42 of the rice or the rice The taste of the selected rice and the hardness, sweetness, and stickiness of the rice selected in the taste display section 44 such as sweetness and stickiness are displayed in an easy-to-understand manner for the user and can be readjusted accordingly.
Accordingly, the control device 20 sufficiently soaks the rice so that a relatively low amount of heat is applied in the soaking extension process C for the first set time x so that the temperature inside the inner pot 6 is soaked and the temperature T1 is maintained. In the second heating extension step G, a relatively high amount of heat is applied for the second set time y, and the temperature inside the inner pot 6 is maintained at the heating temperature T3 so that the rice is further heated. Each process advances in such a state that such an additional process is added to a series of rice cooking processes, and rice cooking is performed.

On the other hand, as above-mentioned, if a separate additional process is not selected for a series of rice cooking processes, a series of preset rice cooking processes will progress, and rice cooking will be performed.
Here, when the user selects the rice cooking course using the menu button 32 and subsequently presses the start button 36, the standby process A is performed in a state where the heating temperature and the heating time of each process are determined by the selected rice cooking course. Since the soaking process B, the first heating process D, the delay process E, the second heating process F, and the steaming process H are sequentially performed and the rice is cooked, the general taste of rice can be obtained.
Next, when rice cooking is completed as mentioned above, the control apparatus 20 adjusts operation | movement of the various heaters 12 and 14 and the heat retention process J is performed so that rice can be heat-retained at uniform temperature.

Hereinafter, another second embodiment for adding the soaking extension process and / or the heating extension process and / or the steaming extension process of the present invention will be described in detail with reference to the drawings.
