技术领域technical field
本发明涉及作为电烹调器的煮饭器。The present invention relates to a rice cooker as an electric cooker.
背景技术Background technique
在最近的微机(Micro computer)控制方式的煮饭器中，具有液晶显示部，根据煮饭器的工作状态(待机中、设定中、设定后、煮饭中、或者保温动作中等)，恰当地显示白米、免洗米等各种煮饭菜单、当前时刻、定时(Timer)煮饭的设定时刻、到煮饭完成的剩余时间、到烹调时完成的剩余时间、保温动作的经过时间等各种信息。In recent microcomputer (Microcomputer) control type rice cookers, there is a liquid crystal display unit, according to the working state of the rice cooker (in standby, during setting, after setting, during cooking, or during heat preservation operation, etc.), Appropriately display various cooking menus such as white rice and non-washing rice, the current time, the time set for timer cooking, the remaining time until the cooking is completed, the remaining time until the cooking is completed, and the elapsed time of the keep warm operation, etc. various information.
在以往的煮饭器中，一般具有如下的显示方法：在时刻、时间等数字的显示中使用7段(Segment)的液晶显示部，另一方面，在该液晶显示部的附近，预先通过印刷等记载有字符，点亮与该字符相对应的标记(Marker)(例如，参照专利文献1)。Conventional rice cookers generally have a display method in which a 7-segment (Segment) liquid crystal display unit is used to display numbers such as time and time, and on the other hand, a liquid crystal display unit is printed in advance in the vicinity of the liquid crystal display unit. etc., and a mark (Marker) corresponding to the character is lit (for example, refer to Patent Document 1).
近年来，提出了如下方案：设置了与上述那样的分段显示方式的液晶显示部不同的、能够显示字符、图样的点阵(Dot matrix)方式的液晶显示部，能够与数字的显示同时地，也将字符、图样显示在任意的位置处(例如，参照专利文献2)。In recent years, it has been proposed that a liquid crystal display unit of a dot matrix (Dot matrix) method capable of displaying characters and patterns, which is different from the liquid crystal display unit of the above-mentioned segment display method, can be displayed simultaneously with the display of numbers. , characters and designs are also displayed at arbitrary positions (for example, refer to Patent Document 2).
这样，当在分段显示方式的液晶显示部的基础上组合了点阵方式的液晶显示部时，能够将当前时刻、定时预约时刻、保温经过时间、各种工作状态等与字符、图样相组合，利用这样组合后的丰富的信息量以容易理解的方式提供给使用者。In this way, when a dot-matrix liquid crystal display is combined on the basis of a segment display liquid crystal display, the current time, timing reservation time, heat preservation elapsed time, various working states, etc. can be combined with characters and patterns. , using the abundant information combined in this way to provide the user with an easy-to-understand manner.
以往，对于煮饭而言，在煮熟后要打开盖对烹调物进行疏松(用英语描述的话，是loose)，由此使得锅内的多余蒸汽和米粒表面附近的多余水分散发出去，防止蒸汽压力引起的米粒的萎缩、水分过剩引起的米粒之间的粘连、以及米粒的过度软化和白化，欲实现味道和外观俱佳的煮饭。In the past, for cooking rice, after cooking, the lid should be opened to loosen the cooked food (in English, it is loose), so that the excess steam in the pot and the excess water near the surface of the rice grains can be released to prevent the steam Shrinkage of rice grains due to pressure, sticking of rice grains due to excess water, and excessive softening and whitening of rice grains are used to achieve cooked rice with good taste and appearance.
特别是在煮饭器中，锅是由金属等通气性和吸水性极低的材料构成的，因此，成为蒸汽和水分难以散发的结构，所以为了实现味道和外观俱佳的煮饭，对烹调物进行疏松的工作是重要且不可欠缺的。因此，提案了一种利用声音来引导对烹调物进行疏松的时机的煮饭器(例如，参照专利文献3)。Especially in rice cookers, the pot is made of materials such as metal with extremely low gas permeability and water absorption, so it becomes a structure that is difficult to emit steam and moisture. Loose work is important and indispensable. Therefore, a rice cooker has been proposed that uses sound to guide the timing of loosening the cooked food (for example, refer to Patent Document 3).

发明内容Contents of the invention
但是，在专利文献2所记载的现有技术中，点阵方式的液晶显示部的显示方法本身没有添加任何特别的想法，没有特别地考虑使用者的操作性的提高。However, in the prior art described in Patent Document 2, no special idea is added to the display method itself of the dot-matrix liquid crystal display unit, and no special consideration is given to the improvement of operability for the user.
此外，虽然在使用说明书等中记载了用于使米饭更加美味地进行食用的煮饭事前准备和煮饭结束后的处理方法，但是煮饭器已经在一般家庭得到普及，不看使用说明书而直接使用的情况较多。因此，对于煮饭的事前准备和煮饭结束后的处理方法，并没有被广泛认知。In addition, although pre-cooking preparations for making rice more delicious and how to handle it after cooking are described in the instruction manuals, etc., rice cookers have become popular in ordinary households, and they can be directly cooked without reading the instruction manuals. There are many cases where it is used. Therefore, the preparation in advance for cooking and the processing method after cooking are not widely recognized.
在煮饭的事前准备中，包括米的计量方法、米的清洗方法、适于煮饭的水、以及米的选择方法和保存方法，如下进行描述。Preparations for cooking rice include how to measure rice, how to wash rice, water suitable for cooking rice, and how to select and store rice, as follows.
关于米的计量方法，如果对于该煮饭器而言并未使用适量的米，那么，难以煮出使用者所喜好的硬度的米饭，所以，如果作为付属品附带有可放入固定量的米的量杯，就能够良好地煮饭。Regarding the metering method of rice, if the rice cooker does not use an appropriate amount of rice, it is difficult to cook rice with the hardness that the user prefers. With a measuring cup, you can cook rice well.
在米的清洗方法中，如果用力洗米的话，则米之间强烈接触而裂开，成为导致粘腻和焦糊的因素，损害了米饭的口感。因此，通过以不使米裂开的方式轻轻地搅拌着清洗，能够煮出更加美味的米饭。In the rice cleaning method, if the rice is washed vigorously, the rice will be strongly contacted and cracked, which will cause stickiness and burning, and impair the texture of the rice. Therefore, more delicious rice can be cooked by gently stirring and washing the rice without breaking it.
关于适于煮饭的水，如果使用pH高的碱离子水，则成为导致粘腻和变黄的因素，损害了米饭的口感。而如果使用硬度高的矿泉水(Mineral water)，则成为导致干燥、发硬的因素，损害了米饭的口感。因此，通过使用pH为中性附近、或者硬度为100以下的自来水或净水器能够煮出更加美味的米饭。As for water suitable for cooking rice, if alkaline ionized water with a high pH is used, it becomes a factor causing stickiness and yellowing, and impairs the texture of rice. On the other hand, if mineral water with high hardness is used, it will become a factor that causes dryness and hardening, and damages the texture of rice. Therefore, more delicious rice can be cooked by using tap water or a water purifier whose pH is around neutral or whose hardness is 100 or less.
关于米的选择方法和保存方法，对于碾米日陈旧的米、开封以后经过一定时间的米、保存在温暖场所的米来说，会发生米的酸化，成为导致变味和变黄的因素，损害了米饭的口感。Regarding the selection method and storage method of rice, for rice that is old on the day of rice milling, rice that has been opened for a certain period of time, and rice that has been stored in a warm place, acidification of rice will occur, which will become a factor that causes odor and yellowing, and damages taste of rice.
因此，通过使用碾米日新的米、开封后尽快食用、或者在冰箱等的暗冷处进行保存，能够用没有酸化的米来煮出更加美味的米饭。Therefore, by using freshly milled rice, eating it as soon as possible after opening, or storing it in a dark and cool place such as a refrigerator, you can cook more delicious rice with non-acidified rice.
煮饭结束后的处理方法包括米饭的疏松方法，如下进行描述。The processing method after the cooking is finished includes the loosening method of the rice, which will be described below.
关于米饭的疏松方法，如果不进行疏松而保持原状的话，多余的水分不会蒸发而成为导致粘腻的因素，损害了米饭的口感。Regarding the loosening method of the rice, if the rice is kept in its original shape without loosening, the excess moisture will not evaporate and become a sticky factor, impairing the texture of the rice.
因此，最初沿着锅的表面放入饭勺、接下来从底部起上下翻动，最后以不挤破米粒的方式将米饭切松来进行搅拌，通过以这样的方式对米饭进行疏松能够更加美味地食用米饭。Therefore, by first putting a rice scoop along the surface of the pot, then turning it up and down from the bottom, and finally loosening the rice so that the rice grains are not broken and stirring, the rice can be eaten more deliciously by loosening it in this way. Serve with rice.
在用声音来引导对烹调物进行疏松的时机的现有煮饭器中，有时会由于使用者没有处于能够听到声音的范围内、或者因噪音等导致来自煮饭器的声音被淹没、或者漏听了来自煮饭器的声音等原因，错过了对烹调物进行疏松的时机，难以实施味道和外观俱佳的煮饭。In the existing rice cooker that uses sound to guide the timing of loosening the cooking material, the sound from the rice cooker may be drowned out due to the user not being in the range where the sound can be heard, or due to noise, etc., or For example, the sound from the rice cooker was missed, and the opportunity to loosen the cooked food was missed, making it difficult to cook rice with good taste and appearance.
本发明为了解决以往的问题点，目的在于提供一种煮饭器，该煮饭器通过在显示部上显示煮饭的事前准备方法、或者煮饭结束后的处理方法，向使用者提供美味的米饭。In order to solve the conventional problems, the present invention aims to provide a rice cooker which can provide the user with delicious food by displaying the method of preparing rice in advance or the method of processing after cooking on the display unit. rice.

An electromagnetic induction coil wound into a ring is used for the heating unit.
如图15所示，锅210由投入规定量的含有水和米的被煮饭物的底部较深的容器构成，由铝和不锈钢的金属包覆材料(Clad material)形成。As shown in FIG. 15 , the pot 210 is composed of a container with a deep bottom into which a predetermined amount of cooked food including water and rice is put, and is formed of clad material of aluminum and stainless steel.
盖体211由对锅210的开口部进行封闭的内盖212和对主体202的开口部整体进行封闭的外盖215等构成。盖体211的一端枢转支撑于主体202的一端，另一端被主体的另一端的卡定机构卡定。内盖212上部设置有压力阀213和使压力阀213开放的压力阀开闭机构219。The lid body 211 is composed of an inner lid 212 that closes the opening of the pot 210 , an outer lid 215 that closes the entire opening of the main body 202 , and the like. One end of the cover 211 is pivotally supported by one end of the main body 202 , and the other end is locked by the locking mechanism at the other end of the main body. A pressure valve 213 and a pressure valve opening and closing mechanism 219 for opening the pressure valve 213 are provided on the top of the inner cover 212 .
如图16所示，压力阀213由阀座213a、金属制的球体214、以及罩213b构成，其中，阀座213a上形成有规定直径的压力阀213，金属制的球体214以封闭压力阀213的方式载置于阀座213a上，罩213b限制球体214的移动，将球体214保持于阀座213a上。As shown in Figure 16, the pressure valve 213 is made of a valve seat 213a, a metal ball 214, and a cover 213b, wherein a pressure valve 213 with a predetermined diameter is formed on the valve seat 213a, and the metal ball 214 is used to close the pressure valve 213. The cover 213b restricts the movement of the ball 214 and holds the ball 214 on the valve seat 213a.
压力阀开闭机构219由缸体(Cylinder)220、柱塞(Plunger)221、以及弹簧和工作杆222构成，其中，缸体220上卷绕有电磁线圈，柱塞221通过电磁线圈的励磁在缸体220内滑动，使球体214移动，弹簧和工作杆222安装在柱塞221的前端。The pressure valve opening and closing mechanism 219 is composed of a cylinder body (Cylinder) 220, a plunger (Plunger) 221, and a spring and a working rod 222. Wherein, the cylinder body 220 is wound with an electromagnetic coil, and the plunger 221 is activated by the excitation of the electromagnetic coil. Sliding inside the cylinder 220 makes the ball 214 move, and the spring and working rod 222 are installed on the front end of the plunger 221 .
压力阀开闭机构219被控制部225控制。即，当根据来自控制部225的指令对电磁线圈进行了励磁时，柱塞221从缸体220飞出与球体214碰撞，将球体214横向压出。通过该压出，球体214从压力阀213上方移动，强制开放压力阀213。The pressure valve opening and closing mechanism 219 is controlled by the control unit 225 . That is, when the electromagnetic coil is excited according to the command from the control unit 225 , the plunger 221 flies out of the cylinder 220 and collides with the ball 214 to push out the ball 214 laterally. By this pushing out, the ball 214 moves from above the pressure valve 213, and the pressure valve 213 is forcibly opened.
在该开放状态下，停止向电磁线圈进行励磁时，柱塞221被弹力拉回到缸体220内，由于这样的回退，柱塞221在横向上对球体214进行按压的力消失，球体214返回到压力阀213上方，压力阀213被球体214封闭。In this open state, when the excitation to the electromagnetic coil is stopped, the plunger 221 is pulled back into the cylinder body 220 by the elastic force. Due to such retraction, the force that the plunger 221 presses the ball 214 in the lateral direction disappears, and the ball 214 Returning above the pressure valve 213 , the pressure valve 213 is closed by the ball 214 .
外盖215上设置有将内盖212和外盖215之间的空间与大气连通的存储箱224。内盖212上设置有安全阀，该安全阀用于在锅210内的压力上升到规定压力以上的异常压力时，使锅210内的蒸汽经由存储箱224逃散到外部。内盖212上安装有蒸汽传感器232(参照图16)。The outer cover 215 is provided with a storage box 224 that communicates the space between the inner cover 212 and the outer cover 215 with the atmosphere. The inner cover 212 is provided with a safety valve for allowing the steam in the pot 210 to escape to the outside through the storage tank 224 when the pressure in the pot 210 rises to an abnormal pressure above a predetermined pressure. A steam sensor 232 (see FIG. 16 ) is attached to the inner cover 212 .
如图15所示，存储箱224具有排出经由压力阀213放出的蒸汽等的排出筒224a、暂时存储作为米饭的美味成分的“米汤”的空室224b、以及将蒸汽放出到外部的蒸汽放出口224c，在空室224b的底部设置有用于使存储的“米汤”返回到锅210内的返回阀V2。As shown in FIG. 15 , the storage box 224 has a discharge cylinder 224a for discharging steam or the like released through the pressure valve 213, a cavity 224b for temporarily storing "rice soup" which is a delicious component of rice, and a steam discharge port for releasing steam to the outside. 224c, a return valve V2 for returning the stored "rice soup" to the pot 210 is provided at the bottom of the empty chamber 224b.
在从压力阀213喷出蒸汽时，该“米汤”与该蒸汽一起从锅210内通过压力阀213被导出，暂时存储在存储箱224的空室224b中。当存储在空室224b的“米汤”达到规定量时，打开返回阀V2使其返回到锅210内。对于存储箱224来说，存储箱224的排出筒224a被压入并固定于外盖215的凹陷部224d所设置的安装孔215a中。When the steam is ejected from the pressure valve 213, the "rice soup" is led out from the pot 210 through the pressure valve 213 together with the steam, and is temporarily stored in the empty chamber 224b of the storage box 224. When the "rice soup" stored in the empty chamber 224b reaches a predetermined amount, the return valve V2 is opened to return it to the pot 210 . As for the storage box 224 , the discharge cylinder 224 a of the storage box 224 is pressed and fixed in the mounting hole 215 a provided in the recessed portion 224 d of the outer cover 215 .

图17是本实施方式中的控制部225的周围的框图。在图17中，控制部225是负责各电路的控制的微机。控制部225连接有：包含模式键、开始键、预约键等的输入部300、显示面板205b、压力阀开闭机构219、锅底温度传感器231、蒸汽温度传感器232、底部加热器233、侧面加热器234、以及盖加热器235。FIG. 17 is a block diagram around the control unit 225 in this embodiment. In FIG. 17, the control part 225 is a microcomputer in charge of control of each circuit. The control unit 225 is connected with: an input unit 300 comprising a mode key, a start key, a reservation key, etc., a display panel 205b, a pressure valve opening and closing mechanism 219, a pan bottom temperature sensor 231, a steam temperature sensor 232, a bottom heater 233, a side heating heater 234, and lid heater 235.
控制部225根据例如存储在闪存(Flush memory)那样的存储元件(未图示)中的控制程序而工作。The control unit 225 operates according to a control program stored in a storage element (not shown) such as a flash memory (Flush memory).
此处，对存储在控制部225中的糙米煮饭流程(Sequence)进行说明。用于煮出更加美味的糙米米饭的基本煮饭方法如下所述。Here, the brown rice cooking process (Sequence) stored in the control part 225 is demonstrated. The basic rice cooking method for cooking more delicious brown rice rice is as follows.
糙米和白米相比，由于表面被种皮包裹，所以拥有热量难以传递到内部，难以吸水的特征，因而要将吸水工序的温度设定得高，将时间设定得长。Compared with white rice, since the surface of brown rice is covered by the seed coat, it is difficult to transfer heat to the inside and absorb water. Therefore, the temperature of the water absorption process should be set higher and the time should be set longer.
在升温工序中，如果用高电力快速升温，则热量不会充分传递到内部，所以将电力设定得低。在沸腾维持工序中，如果电力高，则水很快用光，工序时间变短，热量不能传递到内部。因而会导致加热不足，做出较硬的米饭，所以，较低地设定电力，并且较长地维持沸腾维持工序。In the temperature raising process, if the temperature is raised quickly with high power, the heat will not be sufficiently transferred to the inside, so the power is set to be low. In the boiling maintenance process, if the electric power is high, the water will be used up quickly, the process time will be shortened, and heat will not be transferred to the inside. As a result, heating will be insufficient and hard rice will be made. Therefore, set the power lower and maintain the boiling maintenance process for a longer period of time.
参照图18来说明在上述结构中，使用糙米进行煮饭时的动作。特别是针对粘性糙米煮饭模式的煮饭动作，与图21所示的标准糙米煮饭模式相比较来进行说明。The operation when cooking rice using brown rice in the above-mentioned structure will be described with reference to FIG. 18 . In particular, the rice cooking operation of the sticky brown rice cooking mode will be described in comparison with the standard brown rice cooking mode shown in FIG. 21 .
开始煮饭之后，首先，执行吸水工序。在吸水工序中，使压力阀213成为关闭状态，开始向底部加热器233供电，在规定温度θ1下持续进行规定时间T21的期间。规定温度θ1例如是70℃，规定时间T21例如是45分钟。After rice cooking is started, first, a water absorption step is performed. In the water absorption step, the pressure valve 213 is closed, the power supply to the bottom heater 233 is started, and the operation is continued at a predetermined temperature θ1 for a predetermined time T21. The predetermined temperature θ1 is, for example, 70° C., and the predetermined time T21 is, for example, 45 minutes.
在经过规定时间T21之后，结束吸水工序，转移至升温工序。在升温工序，使压力阀213成为关闭状态，用底部加热器233进行加热。在该状态下，一直升压到使得锅210内的压力上升到能够经由阀孔331上推球体214的压力。After the predetermined time T21 has elapsed, the water absorption step is terminated, and the process proceeds to the temperature raising step. In the temperature raising step, the pressure valve 213 is closed, and heating is performed by the bottom heater 233 . In this state, the pressure is increased until the pressure inside the pot 210 rises to a pressure capable of pushing up the ball 214 through the valve hole 331 .
当蒸汽温度传感器232检测的蒸汽温度K到达作为设定基准的规定温度θ2时，判断为被煮饭物已经沸腾，转移至接下来的沸腾维持工序。规定温度θ2例如是75℃。另外，在图18中，仅在跨越升温工序和沸腾维持工序的一部分中，描绘有表示蒸汽温度K的变化的虚线。蒸汽温度K只用于沸腾检测。关于图19至图21，也是同样的。When the steam temperature K detected by the steam temperature sensor 232 reaches the predetermined temperature θ2 as a setting reference, it is determined that the food to be cooked has boiled, and the process proceeds to the next boiling maintaining process. The predetermined temperature θ2 is, for example, 75°C. In addition, in FIG. 18 , a dotted line representing a change in the steam temperature K is drawn only in a part spanning the temperature raising step and the boiling maintaining step. The steam temperature K is only used for boiling detection. The same applies to FIGS. 19 to 21 .
从吸水工序结束直至达到规定温度θ2为止的时间是利用计时器(未图示)来计时的。计时时间Tf与煮饭量相对应，煮饭量少的时候，计时时间Tf短，煮饭量多的时候，计时时间Tf长。根据计时时间Tf的长度进行煮饭量的判定。The time from the end of the water absorption step until reaching the predetermined temperature θ2 is counted by a timer (not shown). The counting time Tf corresponds to the amount of cooked rice. When the amount of cooked rice is small, the counted time Tf is short, and when the amount of cooked rice is large, the counted time Tf is long. The amount of cooked rice is determined based on the length of the counted time Tf.
此时的锅内压力被压力阀213控制，成为大气压以上的规定压力，例如大约1.2个大气压。到此为止，标准糙米煮饭模式和粘性糙米煮饭模式的流程相同。The pressure in the pot at this time is controlled by the pressure valve 213, and becomes a predetermined pressure above atmospheric pressure, for example, about 1.2 atmospheric pressure. Up to this point, the process for standard brown rice cooking mode and sticky brown rice cooking mode is the same.
在标准糙米煮饭模式中，在沸腾维持工序中，利用压力阀开闭机构219进行压力阀213的开闭控制。通过该控制，压力阀213按照针对每种煮饭模式设定的规定时间单位被多次开放，锅210内的压力从1.2个大气压一直降低到大气压附近。In the standard brown rice cooking mode, in the boiling maintenance process, the opening and closing control of the pressure valve 213 is performed by the pressure valve opening and closing mechanism 219 . By this control, the pressure valve 213 is opened multiple times in predetermined time units set for each rice cooking mode, and the pressure in the pot 210 is lowered from 1.2 atmospheres to near atmospheric pressure.
更详细地，在转移到沸腾维持工序之后，锅210内的压力成为大气压以上的大约1.2个大气压，煮饭物在与该压力相对应的饱和温度下沸腾。在该状态下，当使压力阀开闭机构219工作而使金属制的球体214移动时，阀孔331开放。由于阀孔331的强制性开放，锅210内的压力一直降低到大气压附近。More specifically, after shifting to the boiling maintenance step, the pressure in the pot 210 becomes about 1.2 atmospheres higher than the atmospheric pressure, and the cooked rice boils at the saturation temperature corresponding to the pressure. In this state, when the pressure valve opening and closing mechanism 219 is operated to move the metal ball 214 , the valve hole 331 is opened. Due to the forced opening of the valve hole 331, the pressure in the pot 210 has been reduced to near atmospheric pressure.
当这样地使得锅210的压力从规定沸腾压力(大约1.2个大气压)一次性下降到大气压附近时，锅210内成为剧烈的突沸状态。在该突沸状态下，锅210内产生气泡，利用该气泡来搅拌米。粘性糙米煮饭模式使压力阀开闭机构219成为关闭状态而进行加压。When the pressure of the pot 210 drops from the predetermined boiling pressure (approximately 1.2 atmospheres) to the vicinity of the atmospheric pressure all at once in this way, the inside of the pot 210 becomes a violent bumping state. In this bumping state, air bubbles are generated in the pot 210, and the rice is stirred by the air bubbles. In the sticky brown rice cooking mode, the pressure valve opening and closing mechanism 219 is closed to pressurize.
压力式煮饭器通过在沸腾中升压，提高锅内的沸点，能够进行高温下的煮饭。以发明人的经验来看，加压的时间越长，越能促进米的淀粉的α化(糊化)，此外，高温会引起些许的煮烂，因此能够煮出较软的有粘性且容易感到甘甜的米饭。The pressure rice cooker can cook rice at a high temperature by increasing the pressure during boiling to increase the boiling point in the pot. According to the experience of the inventor, the longer the pressurization time, the more the gelatinization (gelatinization) of rice starch can be promoted. In addition, the high temperature will cause a little boil, so it can be cooked soft and sticky and easy to cook. Sweet rice.
对于糙米而言，由于表面被种皮包裹，即使加长施加压力的时间，糙米也不会被煮烂，能够煮出均衡性好的米饭。For brown rice, because the surface is covered by the seed coat, even if the time of applying pressure is prolonged, the brown rice will not be boiled, and rice with good balance can be cooked.
通过将粘性糙米煮饭模式的沸腾维持工序的电量Whs设定为大于标准糙米煮饭模式的沸腾维持工序的电量Whb，或者，将粘性糙米煮饭模式的沸腾维持工序下的压力阀213的闭合时间设定为大于标准糙米煮饭模式的沸腾维持工序下的压力阀213的闭合时间，能够给米提供较多的热量，结果，能够煮出有粘性的糙米米饭。By setting the electric quantity Whs of the boiling maintaining process of the viscous brown rice cooking mode to be greater than the electric quantity Whb of the boiling maintaining process of the standard brown rice cooking mode, or the closing of the pressure valve 213 under the boiling maintaining process of the sticky brown rice cooking mode The time is set to be greater than the closing time of the pressure valve 213 under the boiling maintenance process of the standard brown rice cooking mode, which can provide more heat to the rice. As a result, sticky brown rice can be cooked.
在沸腾维持工序中，根据煮饭量判定的结果来确定电力。在该电力下进行加热，当检测到规定温度θ3、例如118℃时，维持该规定温度θ3达规定时间T23、例如6分钟。在沸腾维持工序下，经过了规定时间T22时，沸腾维持工序结束，转移至蒸制工序。In the boiling maintenance process, electric power is determined based on the result of determination of the amount of cooked rice. Heating is performed with this electric power, and when a predetermined temperature θ3, for example, 118° C. is detected, the predetermined temperature θ3 is maintained for a predetermined time T23, for example, 6 minutes. In the boiling maintaining process, when predetermined time T22 has elapsed, the boiling maintaining process ends, and it transfers to a steaming process.
在蒸制工序下，在一定时间期间进行多次与煮饭量相对应的加热(再烹煮)。当蒸制工序经过了规定时间T24、例如9分钟时，煮饭结束。In the steaming process, heating (recooking) is performed a plurality of times corresponding to the amount of cooked rice during a certain period of time. When predetermined time T24, for example, 9 minutes has elapsed in the steaming process, rice cooking is completed.
根据以上的煮饭工序，能够得到与煮饭量无关且粘性不同的米饭。由此，即使不变更加水量，也能够提高糙米的分类煮饭性能，能够提供符合客户喜好的米饭。According to the rice cooking process mentioned above, the rice with different viscosities can be obtained regardless of the amount of rice cooked. Thereby, even without changing the amount of water, it is possible to improve the classification and cooking performance of brown rice, and it is possible to provide rice that suits the customer's preference.
此处，“分类煮饭”的意思是，按照使用者的要求将相同的米煮成粘性高的米饭和粘性低的米饭的其中一种，「分类煮饭性能」是指其性能。近年，喜欢糙米米饭的人变多，与白米同样，希望针对糙米分类进行煮饭的要求也不断增加。Here, "sorted rice cooking" means cooking the same rice into one of high-viscosity rice and low-viscosity rice according to the user's request, and "classified rice cooking performance" refers to its performance. In recent years, more and more people like brown rice, and like white rice, there are increasing requests for cooking rice that is classified as brown rice.
另外，本实施方式中的T21、T22、T23、T24、θ1、θ2、θ3的值只是一个例子，可以根据状況来设定数值。In addition, the values of T21 , T22 , T23 , T24 , θ1 , θ2 , and θ3 in this embodiment are merely examples, and values can be set according to situations.
对锅210进行加热的加热部使用了感应加热方式的煮饭器能够以特别高的电力(高火力)进行煮饭，并且，由于热响应良好，所以能够实现细致的控制。因此，如果将本实施方式应用到感应加热方式的煮饭器中，能够煮出更加美味的糙米米饭。即使在加热器式和煤气式煮饭器等中，尽管火力和热响应不佳而导致效果比感应加热式差，但也能够毫无障碍地应用本实施方式。The rice cooker using the induction heating method as the heating part for heating the pot 210 can cook rice with particularly high electric power (high heating power), and fine control can be realized due to good thermal response. Therefore, if the present embodiment is applied to an induction heating rice cooker, more delicious brown rice can be cooked. Even in heater-type and gas-type rice cookers, the present embodiment can be applied without hindrance even though the heat power and thermal response are poor and the effect is inferior to that of the induction heating type.
(实施方式8)(Embodiment 8)
接下来，对本发明的实施方式8进行说明。因为主体的结构与实施方式7相同，所以省略其说明。Next, Embodiment 8 of the present invention will be described. Since the structure of the main body is the same as that of Embodiment 7, description thereof will be omitted.
以下，参照图19对实施方式8的动作进行说明。因为煮饭工序和实施方式1相同，所以省略沸腾维持工序以外的说明。Hereinafter, the operation of Embodiment 8 will be described with reference to FIG. 19 . Since the rice cooking step is the same as that in Embodiment 1, descriptions other than the boiling maintaining step will be omitted.
当转移至沸腾维持工序时，将粘性糙米煮饭模式的沸腾维持工序的电力Ws设定为低于标准糙米煮饭模式的沸腾维持工序的电力Wb，将沸腾维持工序的时间设定得长，由此电量变多，进行加压的时间也变长，能够煮出有粘性的糙米米饭。When transferring to the boiling maintenance process, the power Ws of the boiling maintenance process of the sticky brown rice cooking mode is set to be lower than the power Wb of the boiling maintenance process of the standard brown rice cooking mode, and the time of the boiling maintenance process is set long, As a result, the amount of electricity increases, and the time for pressurizing becomes longer, allowing sticky brown rice to be cooked.
(实施方式9)(Embodiment 9)
接下来，对本发明的实施方式9进行说明。因为主体的结构与实施方式7相同，所以省略其说明。Next, Embodiment 9 of the present invention will be described. Since the structure of the main body is the same as that of Embodiment 7, description thereof will be omitted.
接下来，参照图20对实施方式9的动作进行说明。因为煮饭工序的构成与实施方式7相同，所以省略沸腾维持工序以外的说明。Next, the operation of Embodiment 9 will be described with reference to FIG. 20 . Since the configuration of the rice cooking step is the same as that of Embodiment 7, descriptions other than the boiling maintaining step will be omitted.
当转移至沸腾维持工序时，将粘性糙米煮饭模式的沸腾维持工序中的通电率P设定为低于标准糙米煮饭模式的沸腾维持工序中的通电率P1。此处，通电率是表示每単位时间的通电时间与非通电时间之比的值。由此，沸腾维持工序的时间变长，进行加压的时间也变长，能够煮出具有粘性的糙米米饭。When shifting to the boiling maintaining process, the conduction rate P in the boiling maintaining process of the sticky brown rice cooking mode is set to be lower than the conducting rate P1 in the boiling maintaining process of the standard brown rice cooking mode. Here, the energization rate is a value representing the ratio of the energization time to the non-energization time per unit time. Thereby, the time of a boiling maintenance process becomes long, and the time of pressurization also becomes long, and it becomes possible to cook sticky brown rice.
