Is restricted, and the rice removal valve 22 can be easily attached to and detached from the rice removal shaft 16a.
[0050]
  The operation of the above example will be described. The power switch 84 is turned on, and rice cooking conditions are set according to each operation on the operation panel 11. When the lid 75 is opened and the first setting menu screen mode X is set, the screen is first switched to the rice cooking condition setting screen B, and necessary items are set by the switch group 73. In the first setting menu screen mode X, when switching to the standard screen or the maintenance screen, the individual menu screen is switched by sequentially switching the menu switch 74.(1)-(4)Is displayed. In order to set further details, the menu switch 74 is switched to the second setting menu screen mode Y by pressing (turning on) the menu switch 74 for a long time.(5) (6)Allows additional display of extended function screens. Also for example this(6)In order to determine a selection target from any of the extended function screens, the menu switch 74 is repeatedly pressed. Then, for example, the extended function screen of FIG. 16 is individually displayed to execute a desired operation.
[0051]
  In the above example, switching to the second setting menu screen Y is performed by a special operation such as pressing the menu switch 74 for a long time, but this special operation is not limited to the above and is configured as follows. May be. That is, different functions are provided in the same menu switch, such as making the menu switch have the functions of the push button type and the rotary switch form, and selecting the first or second setting menu screen with the rotary switch.
[0052]
  After setting various rice cooking conditions, when the start switch 80 is turned on, the operation is started, and a predetermined amount of rice is weighed and supplied to the rice washing tank 3. In this rice washing tank 3, the rice is washed with water supply by driving the rice washing motor 20 or the like. That is, it is processed in the order of the wrinkle removal process a, the polishing process b, the rough rinse process c, and the finish rinse process d.
[0053]
  First, in the brewing step (a), water is supplied only from the upper water supply valve 33 in the open state, so that the water is spilled. . Next, in the polishing process step B, the rice in the wet state is agitated by driving the rice washing motor 20, so that the rice cakes and dust are peeled off by the contact action between the rice. Subsequently, the pump 36 is driven while supplying water by operating the upper and lower water supply valves 33 and 35 to supply air, and so-called bubble washing is performed as the water level rises (section T3). Stirring is performed while the loosening of the rice is promoted by the generation of bubbles due to the blowing of air together with the stirring action by the stirring rod, and the separation of the rice cake and garbage separated by the polishing rice is promoted. It is polished again in section T4.
[0054]
  Next, the process proceeds to the rough rinsing process c. Since the rice washing motor 20 is continuously in the driving state, the puckering process is performed in the same manner as in the section T1 in a state of being poured by the water supplied from the upper water supply valve 33 (section T5). In the subsequent section T6, a so-called bubble washing process is performed. Next, the polishing process is performed in section T7, and the rough rinsing process C is completed.
[0055]
  Finally, a finish rinsing step D is performed. In the section T8, the bubble washing rice is executed by the water supply from the lower water supply valve 35. This bubble washing continues until the float sensor 32 is turned on and the sharpening water overflows. When the sensor 32 is turned on, the pump 36 is turned off and the bubble washing rice is transferred to the normal stirring-only washing (section T9), and then the upper side water supply The process is terminated after rinsing with water supplied from the valve 33. The difference between the bubble washing rice processing (section T9) and the section T6 in the finish rinsing process is that the water supply continues until the water supply overflows. It can promote the floating of garbage and garbage separated when stirring while loosening.
[0056]
  If comprised as mentioned above, since the section T2, the section T4, and the section 7 are subjected to the rice polishing process, and the section T3, the section T6, and the section T8 perform the bubble washing process, the polishing process and the bubble washing process are alternately performed. In the rice polishing process, the rice is brought into contact with each other to promote the separation of the rice cakes from the surface of the rice, and then the rice is loosened by the bubble washing rice treatment to promote the separation of the rice cakes.
[0057]
  When the above rice washing process is completed, the rice is cooked after the dipping process. In addition, before turning on the start switch 80, the reservation screen is output by operating the reservation switch, and the cooking time can be cooked at the scheduled time by setting the cooking time and the like.
[0058]
  Although the rice cooking process is executed as described above, the following memory operation means can be executed. For example, when the lid 75 is opened, a memory operation screen is added to the first setting menu screen, and this is selected and set with the menu switch 74, the memory operation screen (FIG. 17) is displayed.(5)') Is displayed and a memo consisting of a combination of the preset amount of rice and the number of pots(1)~ Notes(7)Among these, the configuration can be selected with the setting switch 73. For example, note(1)→ Memo(4)→ Memo(5)The rice cooking is performed in the order of this operation by the set switch 73 operation. In the above example, the first setting menu screen X is incorporated. However, the second setting menu screen Y may be used, or an independent switch operation may be used. Furthermore, the memory content is not limited to the above, and it can be dealt with by previously storing various settings such as operation time and rice washing method in the memory.
[0059]
  On the user's side of the rice cooker, the amount of rice cooked and the rice cooking conditions are almost uniform, and the operator has the disadvantage of having to perform the same rice cooking condition setting operation every day. However, by configuring the memory operation means as described above, such trouble can be eliminated, and the operation can be facilitated and simplified.
[0060]
  FIG. 18 shows the procedure for setting the memo contents. After the standard screen is displayed (FIG. 18).(2)), Open the lid 75, and provide a “memo” field in the selection, and after selecting this, select the amount of rice cooked, how much water is added, how to wash, etc. It is set and stored in the storage device by simultaneous operation of the existing help switch 81 and reservation switch 78 (same as above).(5)). When the help switch 81 is operated again, the screen returns to the standard screen.(6)). The contents stored at that time can be confirmed by opening the lid 75. Other memo contents can be confirmed by calling the memo screen.(7)).
[0061]
  The memory operation means in the above example can be applied to “summary mode” rice cooking in which two or more kettles are continuous and cooked with two cooks being roughly aligned, and “continuous mode” rice cooking in which rice is cooked at substantially regular intervals. In the rice cooking (so-called 1 pot mode), if the memory operation means is applied, the rice cooking conditions of several patterns can be stored in the memory, and the rice cooking can be executed immediately only by the selection operation of each pattern. Facilitates condition setting operations.
[0062]
  Next, the difference in display due to the difference in the rice cooking mode will be described. Before cooking rice, the rice is cooked by absorbing water, and the following two forms are used. That is, water absorption is promoted at a hot water temperature less than or equal to α to reach rice cooking, in which the rice cooker is heated almost simultaneously with the addition of rice (hereinafter referred to as “cooking immediately” mode) and to perform predetermined water absorption. In this mode, a predetermined soaking time is set in advance (hereinafter referred to as “cooking” mode). The immediate cooking mode and the cooking mode are the second setting menu screen mode Y (FIG. 16).(5)It is the structure which can be selected and set from the rice cooker mode screen (FIG. 19) displayed by selecting "rice cooker mode" in a mode setting screen. By the way, when performing rice cooking by timer reservation, it is usually done for the purpose of completing rice cooking after several hours such as timer reservation on the previous day and completion of rice cooking the next morning, etc. Of the two modes, cooking in “immediate cooking” mode has the disadvantage that soft rice can be produced, and wasteful energy is consumed. Therefore, when the “cook immediately” mode is selected and set, the timer reservation is prohibited. As a result, the timer reservation will be cooked only in the “cooking” mode in which the rice has sufficiently absorbed water by soaking, eliminating unnecessary energy consumption and preventing misoperation even if you forget to change the rice cooker mode setting. it can. An alarm is issued and the treatment content is displayed on the display unit.
[0063]
  In addition, when the “cooking immediately” mode is selected and set in connection with rice cooking in the “cooking immediately” mode, the immersion time that can be arbitrarily set is set to “0” or a predetermined short time. . Thus, rice that has been soaked for a long time can be prevented from being “cooked immediately”, that is, cooking rice that is absorbed while heated may result in soft rice or wasteful energy consumption.
[0064]
  If the reserved rice cooking mode is set, after the rice is dropped to the first pot, the storage rice tank 2 and the rice washing tank 3 are integrated with each other based on the forward or reverse command signal of the non-illustrated drive motor. Move towards the top of the hook. However, the movement may stop due to foreign matter being caught in the rollers 86, 87, etc. during the movement. In such a case, an abnormality display and a warning are issued together with the stop of output to the drive motor. And even if the operator removes the cause of the abnormality and tries to move it to the normal position again, the operator usually works at a position away from the rice cooker, so the tank moving direction cannot be recognized. There is nothing.
[0065]
  In order to eliminate the above drawbacks, each moving end is provided with a limit switch, the limit switch operation immediately before the abnormal stop is stored, and the moving direction at the time of recovery from the abnormality can be designated as the left side or the right side. Specifically, among the LED's 77a and 77b arranged on the left and right of the “pot preparation” process in the process display section 77, the LED display in the direction to be moved blinks to prompt the operator to move. And it can move to a normal state by operation of the movement switch 94 arrange | positioned on the left-right wall surface of the rice storage tank 2, and will return from abnormality, if the applicable limit switch turns on. At this time, if the left side wall movement switch 94L is operated, it moves to the left side. Conversely, if the right side wall movement switch 94R is operated, it moves to the right side. Instead of specifying the movement direction, the movement direction may be replaced with a forward / reverse command signal for the drive motor and output.
[0066]
  In FIG. 5, reference numeral 95 denotes a dropping switch for maintaining and fixing the rice removal valve 22 in an open state, which is forcibly actuated by manual operation to lower the shaft 16a and open the rice removal valve 22. As a result, the operator can clean and maintain the vicinity of the jacket 31. Now, the rice washing rice cooking control is performed, but when the pot 6 is not set in a predetermined manner, the rice dropping command signal is output even if the rice dropping from the rice washing tank 3 is executable. First, an abnormal signal is output, and the rice drop is in a standby state. By the way, when a remote signal is transferred from the control unit 96 on the rice-washing rice cooker side to the rice cooker side control unit 97 and a rice cooking command or an abnormal signal input is performed, there is an abnormality in this remote signal. However, in order to avoid this, the present embodiment has the following configuration. That is, by operating the help switch 81 and the dropping switch 95 simultaneously, the rice draining valve 22 is activated regardless of the abnormal signal. Therefore, after confirming the setting state of the pot 6, the immersed rice in the rice washing tank 3 can be discharged as desired and dropped into the pot, and the subsequent rice cooking is performed by operating the ignition switch on the rice cooker side control unit 97 side. Can be executed.
[0067]
  In the above case, the remote signal cannot be received from the rice cooker side, for example, and it is not possible to confirm that the pot preparation is normal. Although the ignition command signal cannot be received, the above disadvantage can be solved by configuring the forced rice removal operation means as described above. There are various setting methods such as providing a dedicated switch instead of operating the help switch 81 and the drop switch 95 simultaneously.
[0068]
  In addition, the following functions are also provided by opening / closing control of the lid 75 of the operation panel 11. When the first or second setting menu screen mode X or Y is set and the maintenance screen is selected, a plurality of inspection processing operations shown in FIG. 21 can be executed. The configuration can be easily cleared by closing the lid 75 (FIG. 21).(3)). When this inspection mode is desired again, it can be handled by opening the lid 75 (same as above).(4)). By doing so, the lid 75 can be closed without any action such as operating the inspection switch or forcibly turning off the power when performing various inspections or stopping the output. All can be reset by and is convenient. In addition, when the lid 74 is opened again, “currently under inspection” is displayed.
