As described above, the display unit 43 drives the display by the display / operation control unit 46 of the control unit 51. At the time of cooking by the rice cooking control means 52 and at the time of heat insulation by the heat insulation control means 53, the temperature to the bottom of the pot 5 by the heating coil 12 and the pot by the body heater 11 are detected by detecting each temperature from the pot sensor 14 and the lid sensor 34. Control is performed such that heating to the side surface 5 and heating to the inner lid 24 by the lid heater 22 are performed. Moreover, after the cooking by the rice cooking control means 52 is finished and the cooked food in the pan 5 is cooked as rice, it automatically shifts to the heat insulation by the heat insulation control means 53, and based on the detected temperature of the pan sensor 14, By adjusting the heating of the pan 5 by the heating coil 21 and the body heater 22, the rice is kept at a predetermined temperature (about 70 ° C. to 76 ° C.).

  And in the said structure, when the rice and water which are to-be-cooked rice are put in the pan 5, and the rice cooking key of the operation part 43 is operated, for example, the rice cooking by the rice cooking control means 52 will start. Here, the rice cooking control means 52 is based on the temperature detection of the bottom of the pan 5 by the pan sensor 14 in order to promote the water absorption of the rice in the pan 5 before starting the substantial rice cooking. The bottom part and the side part of the pan 5 are heated by the body heater 11 respectively, and the water temperature in the pan 5 is kept at about 45 to 60 ° C. for 15 to 20 minutes. Since the inside of the pan 5 is maintained at a reduced pressure at the time, the rice can sufficiently absorb water in the pan 5.

  Thereafter, when the predetermined time has elapsed, the rice cooking control means 52 starts a substantial rice cooking operation, and the pot 5 is heated strongly by the heating coil 12 to boil and heat the food. When the temperature of the bottom of the pan 5 becomes 90 ° C. or higher and the temperature of the inner lid 24 becomes stable at 90 ° C. or higher during the boiling heating, it is assumed that the pan 5 is in a boiling state, and the heating amount is reduced more than before. Shift to continuous boiling heating.

  It should be noted that the fact that the temperature of the inner lid 24 is stable at 90 ° C. or higher is detected by the temperature increase rate of the detected temperature from the lid sensor 34. Moreover, in this boiling detection, it can be confirmed by the pan sensor 14 and the lid sensor 34 that both the bottom of the pan 5 and the inner lid 24 have reached 90 ° C. or more, and it is accurate that the inside of the pan 5 has completely boiled. Can be detected well.

  When shifting to continuation of boiling, the rice cooking control means 52 starts lid heating by the lid heater 22. The lid heating here is managed by the detection temperature of the lid sensor 34 so that the temperature of the inner lid 24 becomes 100 to 110 ° C. And if the bottom part of the pan 5 raises predetermined temperature, the cooking in the pan 5 will be detected, the rice cooking process by the rice cooking control means 52 will be complete | finished, and it will transfer to a heat retention process by the heat retention control means 53, and first It shifts to nomura. During unevenness, the lid heater 22 is cut off by temperature control based on the temperature detected by the lid sensor 34 to prevent the inner lid 24 from being exposed to dew and the temperature is kept high (98-100 ° C.) so that the rice does not burn. The temperature of the bottom of the pan 5 is managed as described. The unevenness is continued for a predetermined time (15 to 20 minutes), and when the unevenness is completed, the operation shifts to heat retention by the heat retention control means 53.

  When the temperature is kept warm, the heating coil 12 heats the bottom and the lower side of the pan 5 so as to be slightly higher than the temperature of the rice accommodated in the pan 5, and the inner lid 24 is heated by the lid heater 22, Furthermore, the temperature of the side surface of the pan 5 is controlled by the body heater 11 so that the rice is not dried and a large amount of dew does not adhere.

  8-10 has shown the rice cooker 1 'of 2nd Example of this invention. In addition, the same code | symbol is attached | subjected to the structure which is common in the rice cooker of a reference example or 1st Example, and the same description is abbreviate | omitted as much as possible in order to avoid duplication. Here, the rice cooker 1 ′ stores rice scoop as an accessory of the rice cooker 1 ′ inside the lid 3 ′, thereby eliminating the need for rice scoop and securing a kitchen space.

  Since rice scoop is good for cooked rice, placing it directly on the floor or desk is a sanitary problem and should be avoided. Conventionally, for example, a rice paddle stand is provided outside the rice cooker, such as the side of the rice cooker, and the rice paddle is stored in the rice paddle stand. However, it is necessary to secure a space for installing a scoop in a limited kitchen, which may cause problems such as difficulty in storage. In order to solve this problem, there has been proposed a rice scoop that does not have a rice paddle and is self-supporting with the spatula portion of the rice scoop up.

  However, since rice scoop alone is arranged separately from the rice cooker, there is a risk that problems such as loss of rice scoop will occur. Therefore, in this embodiment, a storage container 75 for storing rice scoop is provided inside the lid 3 'of the rice cooker 1'.

  The configuration of the present embodiment will be described with reference to FIGS. 8 to 10. Reference numeral 71 denotes a clamp corresponding to an engaging portion between the main body 2 ′ and the lid body 3 ′, and the base end portion is the lid opening button 15. Is supported by the outer lid cover 19 so as to be rotatable around a clamp shaft 72 provided inside the lid body 3. Reference numeral 73 denotes clamp urging means such as a spring for urging the base end portion of the clamp 71 toward the lid opening button 15, and thereby, a force that constantly pushes the lid opening button 15 upwards acts.

  74 is a rice scoop, and 75 is a storage container for storing the rice scoop 74. The storage container 75 is provided on the other side of the storage container main body 75a, the hole 75b provided on one side of the storage container main body 75a, and the storage container main body 75a. And a hook 75c that is engaged with the inside, and is rotatably supported with respect to the outer lid cover 19 around a shaft support portion 76 that is provided inside the lid 3 'and penetrates the hole 75b. . The hook portion 75c is interlocked with the clamp 71, and when the lid opening button 15 is pressed to push the base end portion of the clamp 71 downward and the clamp 71 rotates, the engagement of the hook portion 75c is released. It is configured as follows. When the engagement of the hook portion 75c is released, the storage container 75 rotates around the shaft support portion 76, but when the lid 3 'is opened, a predetermined angle at which the scoop 74 can be easily taken out, for example, the lid 3 The rotation of the containment vessel 75 is stopped at an angle of 45 ° with respect to the lower surface of '.

  Next, with reference to FIG. 10, the operation of the lid 3 'for opening and closing the rice cooker 1' having the above configuration will be described. First, when the lid 3 ′ of the rice cooker 1 ′ is closed, the engagement between the clamp 71 and the hook portion 75 c is not released, and the storage container 75 is housed inside the lid 3 ′ together with the paddle 74. . When the lid opening button 15 is pressed here, the base end portion of the clamp 71 is pushed downward, the clamp 71 rotates against the urging force of the clamp urging means 73, and the engagement of the clamp 71 is released. The Then, the lid 3 ′ automatically opens with the hinge axis of the hinge portion 16 as the rotation center, and the outer lid cover 19 stops at an angle of approximately 90 ° with respect to the main body 2 ′.

  When the clamp 71 rotates, the hook portion 75c interlocked with the clamp 71 moves in the arrow direction, and the engagement of the hook portion 75c is released. Then, due to the gravity of the storage container 75 and the inertial force applied to the storage container 75 when the cover body 3 ′ is opened, the storage container 75 rotates about the shaft support 76 in the direction of the dotted arrow, and the cover body 3 ′ The rotation of the storage container 75 stops at a predetermined angle with respect to the lower surface. In this way, simultaneously with the opening of the lid 3 ′, the storage container 75 appears from the outer lid cover 19 together with the scoop 74. Thereafter, the user takes out the rice paddle 74 from the storage container 75 and uses it.

  After using the rice paddle 74, the user stores the rice paddle 74 in the storage container 75, and rotates the storage container 75 toward the outer lid cover 19 to move it into the lid 3 '. At this time, since the lid opening button 15 and the clamp 71 are returned to their original positions by the urging force of the clamp urging means 73, the storage container 75 is engaged with the inside of the lid 3 by the hook portion 75c. Thereafter, the lid 3 ′ is closed with the hinge axis of the hinge portion 16 as the rotation center, and the main body 2 ′ and the lid 3 ′ are engaged by the clamp 71.

  As described above, the rice cooker 1 ′ of this embodiment includes the clamp 71 that engages the main body 2 ′ and the lid 3 ′, the storage container 75 that stores the paddle 74, and the storage container 75 that is inside the lid 3 ′. A hook portion 75c interlocked with the clamp 71, and when the engagement of the clamp 71 is released, the engagement of the hook portion 75c is also released, and at the same time the lid 3 'is opened, the lid 3' The storage container 75 appears together with the scoop 74 from the outer lid cover 19. For this reason, it is not necessary to secure a space for installing the rice paddle and the rice paddle, and problems such as troublesome storage are not generated. Moreover, since the rice scoop 74 is stored in the lid 3 ′ together with the storage container 75, problems such as loss of the rice scoop 74 do not occur. Therefore, it is possible to secure a limited kitchen space, and to improve the efficiency of the rice that is to be cooked with rice paddle 74, and the convenience is improved.

  FIG. 11 shows a rice cooker 1 ″ according to the third embodiment of the present invention. Note that the same reference numerals are given to configurations common to the rice cookers of the reference example, the first embodiment, and the second embodiment.

  As for the display part of the conventional rice cooker, what was arrange | positioned in front of a main body like the display part 42 of the rice cooker 1 'of 2nd Example was common. However, in recent years, for example, like the display unit 42 of the rice cooker 1 of the reference example, designs that are arranged on the top surface of the lid 3 are also increasing.

  Many rice cookers, for example, the rice cooker 1 of the reference example, have a function of automatically keeping the heat after the completion of cooking, while few things automatically turn off the heat after eating. , The user himself / herself needs to operate the heat retention of the rice cooker. At this time, when the display unit 42 is disposed on the top surface of the lid 3, the display unit 42 faces rearward together with the top surface of the lid 3 when the lid 3 is opened as shown in FIG. 11. Therefore, when checking the display unit 42 in order to turn off the heat retention, it is necessary to close the lid 3 once. Since the main body 2 and the pan 5 are hot immediately after the heat insulation is turned off, the method of opening the lid 3 and taking out the pan 5 after the temperature of the main body 2 and the pan 5 is low is common. When the pan 5 is cooled, the lid 3 needs to be opened. However, in the case of the rice cooker 1 in which the display unit 42 is arranged on the top surface portion of the lid 3, the display unit 42 cannot be visually recognized when the lid 3 is opened. there were.

  Therefore, in this embodiment, the main body 2 is provided with an angle sensor 81 for detecting the lid opening angle of the lid 3 with respect to the main body 2 and the LED 82.

  A rice scoop according to a fourth embodiment of the present invention will be described with reference to FIGS. The rice paddle here is used for the rice cooker in the above embodiments. For comparison, the structure of a conventional rice paddle is shown in FIG. In addition, the same code | symbol is attached | subjected to the structure which is common in a rice cooker of a reference example or the 1st-3rd Example, and the same description is abbreviate | omitted as much as possible in order to avoid duplication.

  Since rice scoop is good for cooked rice, placing it directly on the floor or desk is a sanitary problem and should be avoided. Conventionally, for this problem, a self-supporting rice scoop has been proposed in which the spatula portion, which is a good part of the rice, is installed so that it does not come into contact with the floor or desk as the installation surface, without using a rice scoop. For example, in Utility Model Registration No. 3161134, a gripping handle base end surface is formed into a flat surface, this flat surface is brought into contact with a floor or a desk as an installation surface, and the paddle spatula portion is placed vertically. However, what made rice paddies independent is disclosed. However, this flat surface has a small area with respect to the height of the rice scoop, and there is a possibility that the rice scoop cannot be stably placed vertically. Also, if the flat surface has a sufficient area for the rice paddle to be stably placed vertically, the flat surface may become too large, and it may be difficult to use the rice paddle and secure the installation space. It was. Therefore, with a rice scoop with the base end surface of the grip handle formed on a flat surface, the self-standing shape portion connecting the grip handle and the spatula portion is bent downward, and the lowermost portion of the bending portion is brought into contact with the installation surface. The thing which provided the protrusion part is proposed.

  12A and 12B, a conventional self-supporting rice paddle 74 will be described. The conventional rice paddle 74 is made of polypropylene, and has a spatula portion 91 which is a portion for serving rice and a grip which a user holds. A handle 92 and a self-supporting shape portion 93 formed between the spatula portion 91 and the grip handle 92 are provided. Assuming that the surface 91a of the spatula portion 91 is the upper surface, the self-supporting shape portion 93 is formed in a substantially U-shaped section curved downward, and has a protruding portion 94 at the bottom. The protruding portion 94 extends downward from the self-supporting shape portion 93 and is formed so as to cross the self-supporting shape portion 93 perpendicular to the longitudinal direction of the scoop 74.

  The grip handle 92 is formed in a substantially triangular cross section with a flat upper surface, and includes a grip portion 92 a that is a portion gripped by the user and a base end portion 92 b that corresponds to the base end of the scoop 74. The grip portion 92a is formed so as to gradually become a thin plate shape from the proximal end toward the distal end. The base end portion 92b is formed large and protrudes downward in order to centrally distribute the weight of the scoop 74, and the base end face 92c is formed flat. By configuring in this way, the scooping 74 can be stably placed vertically by bringing the base end face 92c into contact with the installation surface. Further, when the rice scoop 74 is placed horizontally with the surface 91a as the upper side, the rice scoop 74 rotates to the grip handle 92 side with the protruding portion 94 as a fulcrum, and only the lowermost portion of the protruding portion 94 and the base end portion 92b abuts the installation surface. The scoop 74 can be placed horizontally without bringing the spatula portion 91 into contact with the installation surface, and can be kept clean. And the base end part 92b becomes slippery and it becomes easy to hold | grip the holding part 92a.

  However, the conventional self-supporting rice scoop 74 having such a configuration is weaker than ordinary rice scoop with respect to the force required to cook rice, and there is a concern about lack of shape strength. Specifically, the direction of the force applied when the rice is served is indicated by white arrows in FIGS. 11A and 11B, but these forces are strongly applied to the strength of the self-supporting shape portion 93. There is a possibility that, when a large load is applied when trying to cook rice, the self-supporting shape portion 93 may be destroyed by the load, and the scoop 74 may be broken, and the sense of fear that the scoop 74 may be broken. Could not be resolved. Therefore, in this embodiment, ribs 96 and concave portions 97 are additionally provided as reinforcement shapes for the self-supporting shape portion 93 of the rice paddle 74, and the strength is maintained against the load applied when the rice is used, and the self-supporting shape is also provided.

  In recent years, “low protein rice” (a rice grain type rice that has been pregelatinized) has been marketed for use in dietary therapy for patients with renal failure and those with higher blood sugar levels. This “low protein rice” is produced by processing white rice, so it has a high moisture content of 20-28%, and since it is pre-gelatinized, it has a feature of quick water absorption. For this reason, when this low-protein rice is cooked on the white rice course of a conventional rice cooker, the rice that comes in contact with the pan becomes harder or the whole rice becomes too soft. It was difficult to cook rice in the state, and there was a risk of a decrease in taste.

Referring to FIG. 16, a case where rice is cooked in the white rice course of the conventional rice cooker 1 will be described. In the general white rice course, the rice (water absorption process) described in the reference example is controlled by rice cooking as in the above-described reference example. It is incorporated in the means 52. For this reason, low protein rice that absorbs water quickly and has a large amount of water absorbs water in the pan 5 more than necessary, and water is lost at the stage of this process, making it difficult to transfer heat to the center. Furthermore, low protein rice is gelatinized quickly, and the gelatinization starts from the inner surface side of the hot pot 5, so there is no space between the rice grains, water does not pass between the rice grains around the inner surface of the pot 5, and heat is transferred to the center. It becomes difficult to convey. As a result, only the temperature on the inner surface side of the pan 5 becomes high, and the temperature on the bottom surface of the pan 5 reaches the white rice control temperature without the center portion being sufficiently heated, and the rice cooking in the rice cooker 1 is finished. 、 There was a risk of becoming uncooked. Therefore, in the rice cooker 1 ^III of this embodiment, the heating coil 12 is electromagnetic induction heated at 700 W or more, and the rice cooking control dedicated to low protein rice is set so that the rice cooking capacity of the pan 5 is 2 go or less.

The case where low protein rice is cooked with the rice cooker 1 ^III of a present Example is demonstrated referring FIG. First, low protein rice and water to be cooked are put into the pan 5, but in the rice cooker 1 ^III of this embodiment, the rice cooking capacity of the rice to be cooked is a small capacity of 2 go or less, A low protein rice dedicated to cooking low protein rice and a water level line (not shown) of the amount of water are provided, and low protein rice and water are put into the pan 5 according to this water level line.

  Next, when the lid 3 is closed and the operation unit 43 is operated and, for example, a low protein rice course is selected, rice cooking by the rice cooking control means 52 starts. Here, in the heating pattern of the low protein rice course, as shown in FIG. 17, the “meat” process is omitted, and based on this, the rice cooking control means 52 turns off the energization from the heating coil 12 from the start of rice cooking to boiling. By heating up to boiling at once without heating, heating with less water becomes possible. Moreover, the electromagnetic induction heating of the heating coil 12 by the high frequency current is performed at 700 W or more, and the low protein rice is cooked at a stretch, so that the rice in the pan 5 can be cooked without extra water absorption. Therefore, low protein rice can be cooked more deliciously and easily. Since the subsequent steps are described in detail in Japanese Patent Application Laid-Open No. 2006-081656, description thereof will be omitted.

As described above, the rice cooker 1 ^III of this embodiment heats the main body 2 having the pan 5 for storing the low-protein rice and the water to be cooked, the pot housing portion 4 for storing the pan 5, and the pan 5. A heating coil 12 as a heating means, and a rice cooking control means 52 as a control means for controlling the heating coil 12, and the pan 5 has a rice cooking capacity of cooked rice of 2 go or less, The rice cooking control means 52 is provided with low protein rice and water level lines, and the heating coil 12 performs electromagnetic induction heating when the heating coil 12 is 700 W or more, and the heating pattern in which the heating pattern is omitted is used as a low protein rice dedicated rice cooking control. The heating coil 12 is controlled in a low protein rice course. Therefore, it becomes possible to heat with less water, and by cooking low protein rice at once, the rice in the pan 5 can be cooked without excessive water absorption, making low protein rice more delicious and easy. Can be cooked.

  A storage structure of the rice cooker accessory in the outer box according to the sixth embodiment of the present invention will be described with reference to FIG. The rice cooker accessory here is used for the rice cooker in each said Example. For comparison, FIGS. 18 to 21 show a conventional storage structure of rice cooker accessories in an outer box. In addition, the same code | symbol is attached | subjected to the structure which is common in a rice cooker of a reference example or 1st-5th Example, and the same description is abbreviate | omitted as much as possible in order to avoid duplication.

  Conventionally, the exterior box is made of, for example, corrugated cardboard, and is used for transporting home appliances such as a rice cooker. A packaging packing made of, for example, styrene foam is provided in the exterior box, and the household appliance is held so as not to move in the exterior box by the packaging packing to protect the household appliance. In addition, accessories for home appliances are usually stored together with the home appliances in an exterior box. At this time, such accessories may be stored in home appliances or in packing packing. There were many.

If it demonstrates, the measuring cup 103 will be accommodated in the pan 5 which is in the rice cooker 1 as shown in FIG. 18, and it was surrounded by the exterior box 101 and the packaging packing 102 as shown in FIG. The scoop 74 is stored in the space 105 in the packaging packing 102.

  However, depending on the state in which the measuring cup 103 and the rice scoop 74 are stored, the measuring cup 103 comes into contact with the inner surface of the pan 5 due to vibration during transportation or dropping of the outer box 101 or the scoop 74 is attached to the outer lid 19 or the main body 2. There was a risk of contact with the outer surface and damage or deformation. In addition, when the shape of an accessory such as rice paddle 74 is changed, it is necessary to change the shape of the packaging packing 102, that is, change the mold of the packaging packing 102, and the storage cost in the packing packing 102 is changed. Was expensive. Therefore, as a countermeasure for preventing these scratches and deformations, a storage structure using a dead space 106 formed between the outer box 101 and the rear portion of the rice cooker 1 as shown in FIG. 20 has been proposed.

  As shown in FIG. 21, the length in the longitudinal direction of the two packing packings 102 is shortened, and the upper end is bent into the dead space 106 at the rear of the rice cooker 1 between the packing packing 102 and the outer box 101. An L-shaped partition plate 108 is disposed, and the power cord 104 is stored in a space 109 between the outer box 101 and the partition plate 108. However, this is not a measure for the storage of accessories such as the measuring cup 103 and the rice paddle 74, and the problem of storage in the packaging packing 102 has not been solved. Furthermore, as shown in FIG. 21, when the inner lid 110 is installed across the upper edges of the two packings 102, the dead space 106 at the rear of the rice cooker 1 and the dead space 107 at the front of the rice cooker 1 are still widely present. Accessories could not be stored, and dead spaces 106 and 107 could not be used effectively. Therefore, in the present embodiment, the support plate 111 as an inexpensive plate is added above the rice cooker 1 as a product, and the dead spaces 106 and 107 are used to prevent the rice cooker 1 from being damaged or deformed. A rice paddle 74, a measuring cup 103, and a power cord 104 are housed.

  The case where the scoop 74, the measuring cup 103, and the power cord 104 of the present embodiment are stored in the outer box 101 will be described with reference to FIG.
