The action process of rice washing and rice cooking is as follows: weighing by the measuring device 20 → washing the rice by the rice washing device 9 → immersing the rice washing portion (zari-raising) by the intermittent shower from the upper shower 41 in the rice washing device 9 → left by the moving base 18 of the rice washing device 9 , Rightward movement → water adjustment in the rice washing machine 9 → rice discharge by opening the discharge valve 28 → immersion of the rice cooker 10 in the inner pot 13 → rice cooking by gas ignition → murashi → replacement of the inner pot 13 after rice cooking This is a configuration that goes through the respective steps.
[0019]
In the mode in which the single rice washer 9 moves to the left or right and cooks rice while switching and supplying rice to the two left and right rice cookers 10a and 10b, the immersion process is performed by the immersion setting switch 65 as the immersion time. By appropriately setting the time, each rice washing process and the rice cooking process in each of the rice cookers 10a and 10b can be continuously performed, so that an efficient operation of all the steps from rice washing to rice cooking can be performed. Of the respective steps, those whose time is changed are mainly the immersion step and the unevenness step, and the ratio between the rice washing section immersion and the kettle immersion may be changed. The setting of the immersion time by the immersion setting switch 65 may be changed and set for either one or both. These immersion times are calculated by the CPU to calculate and control the kettle immersion time after the rice washing. Water adjustment is started by the outputs of the on-off valves 40a and 40b so that the immersion time coincides with the set value. The start of such water adjustment starts the end of the rice cooking process of the rice cooker 10a or 10b.

The setting of the degree of washing includes setting the rice washing time, upper water supply time, lower water supply time, drainage time, the number of repetitions of the rice washing, etc., the time of the entire rice washing process, etc. by finishing with bran removal, polishing rice, rough rinsing and overflow. The setting is changed for each process such as rinsing and the like, and five-stage settings to be carefully performed from the mode for lightly washing rice are stored in the washing method display window 5 so as to be displayed.
[0023]
The water level setting is performed by operating the water level setting switch 2 in accordance with the increase / decrease data of one range of the fine adjustment range consisting of seven steps from the center to the increasing side and the decreasing side displayed on the water level display window 3. As shown in FIG. 6, the center position of the increase / decrease data is set to match the user's needs in response to various conditions such as a wide variety of varieties including foreign rice, as in recent years. The increase / decrease data of the five ranges shifted to the five stages is prepared in the memory of the rice-washing / cooking control device 1, and the increase / decrease data is set by appropriately switching these increase / decrease data.
[0024]
In the setting procedure, as shown in the flowchart of FIG. 7, first, it is checked whether the water addition / decrease setting switch 2 and the changeover switch 6 are turned on at the same time. Further, it is checked whether only the changeover switch 6 has been operated. If YES, the water addition / decrease setting is END. If NO, it is checked whether the increasing side of the water addition / decrease setting switch 2 is ON, and if YES, It is checked whether the increase / decrease data of the range currently displayed in the display window 3 is the MAX value on the side with the larger value, and if NO, the fine adjustment range is increased by one step, and if YES, the increase is increased. In addition to switching and displaying the increase / decrease data of the side range, by switching the display range of the display window 3, the display of the range position using the washing display window 5 is turned on by one step. , The fifth stage of the washing side display window 5 to check whether the lights, to stop at the many side of the MAX value if YES.
[0025]
If the increase side of the water addition / decrease setting switch 2 is NO, it is checked whether the decrease side is ON. If YES, the MIN value of the range whose change data of the range currently displayed on the display window 3 is smaller is smaller. Is checked, and if it is NO, the fine adjustment range is turned on by one step, and if YES, the increase / decrease data of the decrease side range is switched and displayed, and the display range of the display window 3 is switched. The display of the range position using the washing method display window 5 is turned down by one step, and it is checked whether the first stage of the washing method display window 5 is turned on. If YES, the MIN value on the smaller side is used. Stop. The number of stages and the number of ranges in the fine adjustment range of the increase / decrease data are not limited to the present embodiment.
[0026]
To adjust the water level of these water levels, the opening and closing device 40a is opened and water is supplied from the lower nozzle 37 into the rice washing machine 9. When the water overflows from the overflow port 48, the water supply is stopped. The water reduction control is performed so that the water level is set according to. The rice cooker 10 pushed into the machine frame 11 together with the gas stand 12 is positioned such that the center of the rice cooker 10 is located immediately below the discharge valve 28 of the rice washing machine 9, and the discharge valve 28 is opened by driving the discharge motor 31 to adjust the water level. Is dropped into the rice cooker 10 with the lid 14 opened. When the cooked rice cooked by the completion of rice cooking is taken out of the machine, the handle 15 is pulled out together with the gas stand 12 to the outside of the machine, the inner pot 13 is pulled up from the rice cooker 10 and the next inner pot 13 is set.
[0027]
In addition, when performing rice washing and rice cooking, it is necessary to set in advance a function classification item (see FIG. 9) which is an operating condition for this, but this function classification item is stored in the rice washing rice cooking control device 1. Normally, it is set to the initial mode (* mark shown in FIG. 9). When it is necessary to change the initial mode, as shown in the flowchart of FIG. 10, it is checked whether the mode setting switch 69 and the changeover switch 6 are simultaneously turned on. If NO, the process returns to the normal operation process. When YES, the mode is shifted to the selection mode, and the number of each function item is displayed using the immersion display window 66, and the number of the selection item in each function item is displayed using the spot display window 68. Let it do.
[0028]
Next, in such a selection mode, it is checked whether or not the + side or the − side of the immersion setting switch 65 is turned on while the changeover switch 6 is kept in the ON state, and if YES, the immersion display window 66 is displayed. Increase or decrease the number of each function item. Further, in this state, it is checked whether or not the plus side or the minus side of the spot setting switch 67 is turned on while the changeover switch 6 is kept in the ON state, and if YES, the respective function items displayed in the immersion display window 66 are checked. , The number of the selection item displayed on the spot display window 68 is increased or decreased. These series of mode changes are completed when the changeover switch 6 is OFF, and return to the normal operation process.
[0029]
For example, when the number of the immersion display window 66 is 16 and the number of the spot display window 68 is 01, "cooking in the rice cooker mode" is selected. As described above, by using the immersion setting switch 65, the immersion display window 66, the spot setting switch 67, the spot display window 68, the mode setting switch 69, the changeover switch 6, etc. Selection of a large number of function items can be accurately set with simple operation by processing of the function software so that it can be matched to the user's needs according to the conditions, and it is possible to suppress the addition in terms of cost It is.
[0030]
As shown in FIG. 11, in the rice washing process in which the drain valve 35 is opened, the upper shower 41 is opened by the on-off valve 40b, and the rice is washed while supplying water, the drain valve 35, the overflow port 48, the drain hose 81 and the like are clogged with garbage. When drainage becomes impossible, there is a possibility that electric components and the like attached to the upper side wall surface of the rice washing machine 9 may be flooded by water overflowing from the rice washing machine 9.
[0031]
In order to prevent this, since the volume from the time of detection of the water upper limit sensor 47 to the overflow of the water (the hatched portion in FIG. 11) is known in advance, the water supply stop position S which has a little margin from the upper limit of the overflow is set. Is set, and the volume based on this setting is converted into the integrated value of the flow rate pulse by the flow rate sensor 38. As shown in the flowchart of FIG. 12, the procedure for stopping water supply at the S position based on this integrated value is to check whether or not the water upper limit sensor 47 has been turned on by the rise of the float 47a in the rice washing process. Start integration of. Next, it is checked whether or not this integrated value has reached the volume at the S position. If the answer is YES, the on-off valve 40b is closed to stop water supply, and the abnormality processing is notified. As described above, when an abnormality occurs in the rice washing process, the overflow of water from the rice washing machine 9 can be prevented by the control of the CPU. Safety can be ensured. The water upper limit sensor 47 is configured to be turned off when the float 47a is at the lower end position and turned on when the float 47a is moved up to the stopper 47b position.
[0032]
Further, as an embodiment different from the above, turning on the water upper limit sensor 47 even though the drain valve 35 is open is not in a normal state, but the drainage is poor due to scrap rice or the flow rate is low. This phenomenon is often observed when the amount of water is too large, and if the abnormal processing is performed in such a state, the work efficiency becomes extremely poor. Since it is possible to prevent overflow of water by drainage from 48, the movement of the float 47a of the water upper limit sensor 47 is the same until it is turned on in the upward movement position as described above, and as shown in FIG. By removing the stopper 47b at the time of ON and by using a reed switch or the like to turn it off again when the stopper 47b is further moved upward from the position of the stopper 47b, 7 to stop the water supply by detecting the upward movement OFF of notifying the abnormality processing.
[0033]
The water supply stoppage due to the OFF detection of the water upper limit sensor 47 is delayed in consideration of the chattering and the time from the OFF position to the full state (for example, about 5 seconds). When the water upper limit sensor 47 detects ON again during this delay processing, the water level has decreased, so the water supply stop processing is canceled and the state returns to the initial state. By such processing, overflow of water can be prevented without significantly impairing the work efficiency.
