Then, especially in the vicinity of the bottom in the rice washing tank 5, the rice is agitated by the agitation bars 135, 135, and bubbles are generated by the ejection of air to become a bubble-washed rice state, so that a high rice washing effect can be obtained.

Next, operation of the rice cooker will be described.
First, in the control unit 69 of the computer, the rice cooking device is operated such as the amount of rice cooking, the rice washing time (rotation time of the stirring bar 135), the rice polishing time (rotation time of the stirring bar 135), the immersion time in the rice washing tank or the pot. Necessary conditions are configured to be set by an operation panel (operation display device) 70 disposed on the front door portion of the cover member 23.

  FIG. 9 shows a state in which the switch cover 71 of the operation panel (operation display device) 70 is closed (FIG. 9A) and an open state (FIG. 9B). On the operation panel 70, a process display section 72, a reservation switch 73, a setting switch group 74, a start switch 75, a help switch 76, and the like are arranged, and a liquid crystal display screen 77 is provided below. In the process display section 72, a preliminary process consisting of rice weighing, washing and soaking (immersion), and preparation of the pot, soaking (immersion), ignition, rice cooking, unevenness, rice cooking process consisting of cooking, respectively, It is possible to identify which process is currently being executed by turning on the LEDs 78, 78... Provided for each process display unit, so that light is emitted in two colors of green in a normal operation state and red in an abnormal state. , So that the driving state can be easily recognized.

  The setting switch group 74 is provided with “UP (+)”, “DOWN (−)”, and “Feed” switches on the top, bottom, left, and right, and main setting changes such as the number of pots to be cooked, cooking time, etc. It is the structure which can be set.

  Further, the lower part of the operation panel 70 has the switch cover 71 that opens and closes at the horizontal axis fulcrum, and when the cover 71 shown in FIG. 9A is closed, the liquid crystal display screen 77 is a normal operation display screen. A is displayed. In the form of this embodiment, the total number of times of rice cooking (corresponding to the number of rice cookers; hereinafter referred to as the total number of rice cookers), the number of times of continuous rice cooking (hereinafter referred to as the number of pots to be cooked), the capacity to be processed with a single rice cooking, how to cook rice (Mode), the total soaking time and the steaming time in the rice cooking preliminary process and the rice cooking process are displayed.

  FIG. 9B shows a state where the switch cover 71 is opened. The cover 71 is provided with a cover open / close detecting means 79 comprising a photocoupler and a reflecting plate and a locking portion 80. When the cover 71 is opened, the cover open / close detecting means 79 is turned off, and the liquid crystal display screen 77 is operated normally. A screen on which the rice cooking conditions can be set immediately from the display screen A is displayed. Hereinafter, this screen is referred to as a rice cooking condition setting screen B. Rice cooking condition setting screen B is a screen that can set any rice cooking condition among the amount of rice cooking, water adjustment, washing method, soaking time, steaming time, cooking method (mode), ignition method, and for each cooking condition The rice cooking conditions can be determined by setting switches 81, 81. A power switch 82 is disposed below the operation panel 70.

  The control unit 69 also has the following functions. In other words, it has a normal rice cooking mode that cooks white rice under normal water adjustment and a rice cooking mode that cooks water according to a specific heating program with more water addition and reduction than the normal rice cooking mode. It can be set. Note that the normal rice cooking mode and the rice cooking mode are configurations that are automatically set by comparing the amount S of rice cooking with a predetermined amount A set in the control unit 69 in advance.

  For example, in contrast with the predetermined amount A, when the set rice cooking amount S is large (S ≧ A), the “normal rice cooking mode” is set. Further, when the set rice cooking amount S is small (S <A), the “rice cooking rice mode” is set.

  Depending on the difference between the above-mentioned “normal rice cooking mode” and “boiled rice cooking mode”, the water heating / discharging and rice cooking heating programs are different, and each is controlled and operated according to the program stored in the control unit 69. For example, regarding the water addition / reduction process, when the water addition / reduction process starts, as shown in FIG. 11, first, the predetermined amount A (set to 2 升) is compared with the set rice cooking amount S (S101), 2 升. When it is above, it is set to the normal water adjustment mode (S102), and when it is less than 2 kg, it is set to the rice water adjustment mode (S103). Specifically, the water level valve 65 opening time T for adjusting the water level with the water level valve 65 from the overflow state from the rice washing tank 5 is set based on a table or a relationship graph set for each mode. In the normal water mode, the opening time T of the water level valve 65 is set to TS (S104), and in the rice water mode, the TN is set to TN (S105). When such mode setting and selection of the water level valve opening time are performed, both the drain valve and the water level valve are closed (S106), and water supply is performed (S107). Or may be configured to allow simultaneous selection of both upper and lower water supplies).

  Eventually, the overflow sensor 68 is turned on (S108), but the water supply is stopped (S109), and the water level valve 65 is opened (S110). As the water level valve 65 is opened, the rice washing tank 5 is drained, and after a predetermined time has passed, it is closed to obtain a desired water level, that is, a water level (S112 to S115). Here, in the normal water addition / subtraction mode, TS is called as the water level valve opening time (S115), and rice cooking water about 1.2 times the amount of rice cooking is ensured. Further, in the rice water addition / subtraction mode, TN is called as the water level valve opening time (TS <TN) (S114).

  Therefore, these times are managed by the timer set, and when the timer outputs the passage of the above time, the timer is up and the water level valve 65 is closed (S116), and the predetermined water level adjustment is completed.

Then, when it comes to the rice cooking process, as shown in FIG. 12, about the process procedure, normal rice cooking mode setting and rice cooking rice mode setting are selectively set. In the normal rice cooking mode, the rice is cooked along a heating program for normal rice cooking, and in the rice cooking mode, the rice is cooked along a heating program described below.
The predetermined amount A is set in consideration of the maximum capacity Q of the rice washing tank 5. The amount of cooked rice S and the necessary amount of water addition / reduction W are in a proportional relationship, for example, W = pS + q (p and q are constants). Therefore, the total amount is S + W = S + pS + q = (1 + p) S + q. When the maximum capacity Q is taken into consideration, the maximum value of the rice cooking amount S satisfying Q <(1 + p) S + q may be set as the set value A.

  Moreover, since the said constant p is different in the case of adding and subtracting water for normal rice cooking and in the case of adding and subtracting rice for cooking rice, the set value A is naturally different. That is, the regular rice cooking water amount WS and the cooked rice water amount WN have a relationship WS <WN, and the regular rice constant p (= pn) for the regular rice cooking constant p (= pn). Since the value is several times larger, the set amount A is selected as a value for cooking rice (FIG. 13).

Next, an embodiment of the drive configuration of the rice removal valve 139 will be described with reference to FIG.
The drive configuration of the rice draining valve 139 is such that when the rice draining valve 139 is removed from the rice draining shaft 138 and cleaned, it is fixed so that the rice draining shaft 138 does not slide up and down, and is easy to install. Is.

  A rice draining shaft 138 is loosely fitted in the hollow rotating shaft 134 so as to freely slide up and down, and a rice draining valve 139 is attached to the lower end of the rice draining shaft 138. An intermediate part of a dropping arm 92 that moves up and down like a seesaw is pivotally supported on the mounting member on the upper part of the rice washing tank 5, and one end of the dropping arm 92 is connected to the upper end of the rice discharge shaft 138 with a pin 93. A drop cam 141 driven in the direction of the arrow by a rice removal valve drive motor 140 is linked to a roller 94 provided in the section so as to be movable, and the rice removal valve 139 is moved up and down to open and close the lower opening of the rice washing tank 5. It is. A stopper 95 is provided to stop the downward rotation of the one end side of the dropping arm 92 at a predetermined position.

  In the state shown by the solid line in FIG. 10, the large-diameter portion of the dropping cam 141 comes into contact with the roller 94 of the dropping arm 92, lifts the left boom of the dropping arm 92, and the rice removal shaft 138 and the rice removal valve 139 through the dropping arm 92. The rice removal valve 139 is closed. Next, when the dropping cam 141 further rotates counterclockwise, it rotates while pressing the left side portion of the dropping arm 92, and when the large diameter portion is separated from the roller 94, the left side of the dropping arm 92 is the rice removal valve 139 or the like. , The rice removal shaft 138 is also moved downward, and the rice removal valve 139 is opened (imaginary line in FIG. 10).

The operation of the above example will be described.
When the power switch 82 is turned on, rice cooking conditions are set according to each operation of the operation panel 70, and various rice cooking conditions are set, when the start switch 75 is turned on, the operation is started as in the rice cooking flow shown in FIG. .

That is, the power switch is first turned on (step 1), then the rice cooking conditions are set and input (step 2), and the start switch 75 is pressed (step 3). Then, a predetermined amount of rice is supplied to the rice washing tank 5 and washed in step 5.
The rice washing process in step 5 is a brewing process in which rice is stirred while dripping water, a polishing process in which water is drained once and drained and the rice is stirred in a wet state, a rough rinsing process in which rice is stirred at a predetermined water level, and water is stored in a tank. It consists of a final rinsing step that stirs while overflowing.

  After the rice washing process in step 5 above, the process proceeds to a water addition / reduction process in step 6. In this step 6, based on the flow of FIG. 11, it is set to the “normal rice cooking water mode” or “boiled rice cooking water mode” as described above, and the amount of rice in the rice washing tank 3, the quality of the rice, the temperature The microcomputer calculates the amount of water suitable for the water temperature, etc., supplies the rice washing tank 5 with water, and after the rice washing tank 5 is full, the water level valve 65 is calculated for the calculated time, ie, TS or TN is opened to adjust the water amount. do.

  The amount of water added to cooked rice is about 1.2 times the amount of cooked rice, while the amount of water added to cooked rice cooked with rice is about 5 times the amount of cooked rice. There is a limit to the amount that can be accommodated in the rice cooker, and even if 5 kg of rice can be cooked with regular rice using a commercial rice cooker, the rice cooked with rice is 2 kg or less. Depending on whether or not the predetermined amount is exceeded, the control unit 69 automatically selects the “normal rice cooking water adjustment mode” or the “rice cooking rice water adjustment mode”, and obtains a predetermined water adjustment based on it. Therefore, it is possible to simplify the operation by eliminating the need for selecting and setting whether normal rice cooking or rice cooking is required.

In step 7, the washed rice in the rice washing tank 5 and the measured water in step 3 are dropped into the rice cooker 7 by opening and closing the rice drain valve 139.
In step 8, the rice in the rice cooker 7 is immersed in water for a specified time. After the specified time has elapsed, ignition is performed in step 9, rice is cooked in step 10, steamed in step 11, cooked in step 12, and predetermined cooked rice is completed.
In addition, before the start switch 75 is turned on, a reservation screen is output by operating a reservation switch, and cooking can be performed at a scheduled time by setting a cooking time and the like.

That is, even in the case of non-washed rice that omits the rice washing treatment, the rice washing tank 5 (or a container instead of this) may be used to adjust the amount of water based on the amount of rice cooking A. From the relationship between the amount of cooked rice and the amount of water added, the configuration disclosed in each claim can be taken to facilitate the operation.

  Moreover, in the said Example, it was set as the form which secures predetermined water amount, reducing water adjustment from the full state of a rice washing tank by opening the water level valve 65 one by one. However, it is not limited to this form. It may be configured to be managed.

  Next, a rice cooking container (cooking rice cooker) dedicated to rice bowl will be described. FIG. 17 is a partially broken side view of a rice cooking container dedicated to rice cooking, and FIG. 18 is a plan view thereof. The rice cooking container 31 is detachably provided with a middle and high shape upper lid 32 that closes the main body opening and has a high central portion. The upper lid 32 is formed with a relatively small central hole 32a so as to block the central hole 32a. A slide shutter 33 is attached to be openable and closable.

  The peripheral edge of the opening of the main body of the rice cooking container 31 is further expanded to raise the outer peripheral wall 31a. The outer peripheral wall 31a rises at least to a height exceeding the middle stage of the upper lid 32, so that the liquid pool extends to the upper side of the upper lid 32. Part A is formed. In the outer peripheral part of the upper lid 32, for example, a plurality of return holes for returning the rice cooking liquid blown out during the cooking and one punching hole 36 for releasing the internal pressure during the cooking for each of a plurality of radial line positions arranged at three locations, etc. The holes 35 are formed through. The one radial line position is adjusted to the direction of the left and right receiving portions 31b and 31b of the rice cooking container 31.

  Specifically, a wall-like rising portion 34a lower than the upper end position of the outer peripheral wall 31a is formed on the outer periphery of the upper lid 32 as shown in the enlarged sectional view of FIG. As shown in the enlarged cross-sectional view, after the inclined portion 34b that is uniformly inclined is formed, the rising portions 34a or the lower portions of the inclined portion 34b are arranged with the plurality of return holes 35. The pressure release hole 36 is disposed at a position substantially corresponding to the height of the upper end of the outer peripheral wall 31a on the rising portion 34a or the middle step portion 37 rising inward from the inclined portion 34b.

  The slide shutter 33 has a knob 38 protruding from the center thereof, and a shutter frame 33a is attached via a collar 39 in order to ensure a certain gap G above the center hole 32a of the upper lid 32. Specifically, as shown in FIG. 20, an enlarged view of part A of the rice cooking container in FIG. 17 is set such that the gap G is within a range where the rice cooking pressure can be secured by the flow path resistance from the center hole 32 a to the atmosphere. .

  In the rice cooking container 31 having the above-described configuration, a large amount of rice cooking liquid blows out from the center hole 32a of the upper lid 32 and the plurality of press-off holes 36 when the rice is cooked or cooked with extremely large amounts of water. In addition to being stored in the liquid reservoir A by the outer peripheral wall 31a of the main body, it is returned to the inside of the rice cooking container 31 from the plurality of return holes 35. At this time, the gap G between the center hole 32a of the upper lid 32 and the slide shutter 33 secures a predetermined rice cooking pressure and reduces extreme spillage. Therefore, the rice cooking container 31 can prevent spilling to the outside of the container without sacrificing the rice cooking conditions, improve the hygiene, and prevent the rice cooking stove from being damaged.
