Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cooker that has improved hinge strength and commercial value of the cooker, and has a compact design of the main body.
[0002]
[Problems to be solved by the invention]
In recent years, cookers that open the lid with one-touch opening have become mainstream, and in order to open with one-touch opening, an elastic body such as a torsion coil spring is arranged at a hinge portion, and the lid is opened using the elasticity.
[0003]
In order to improve the appearance quality and design, the outer cover made of synthetic resin as the appearance is provided with metal parts made of stainless steel or the like as the appearance parts. Alternatively, a display unit is provided on the lid. In either case, the lid becomes heavy, and a spring having a large elastic force is required to open the heavy lid with one touch. When designing a spring having such a large elastic force, the spring wire diameter is increased, the number of turns is increased, and the spring outer diameter is increased. The aim is to extend the life of the spring in order to secure the minimum number of times the lid must be opened as a product.
[0004]
Further, when the lid is opened, it is necessary to regulate the opening of the lid at a certain angle. If this regulation is not implemented, the lid will continue to open forever and eventually fall, resulting in no commercial value. In order to restrict the opening of the lid, stopper portions are provided on the hinge portion on the main body side and the hinge portion on the lid side, respectively. The mainstream design is to make the stopper work at an angle where the cooking pot can be taken out with the lid open.
[0005]
There is also an improvement in design, and the external shape of the lid is a complicated three-dimensional shape. In many cases, synthetic resin is used for the external part. There are many. The above-mentioned stopper portion is also often made of synthetic resin.
[0006]
When the lid is opened, the elasticity of the elastic body causes the lid to have energy.When the main body stopper and the lid stopper come into contact with each other, force is applied to both stoppers.If the elastic body has a large force, the inertia of the lid In some cases, the front side of the main body is lifted by force. When the lid is heavy, since the elastic force is large, a greater force is applied to both stopper portions, and an excessive force is applied to both stopper members made of synthetic resin, which may cause damage. If the lid is opened while the product is warm, such as immediately after cooking, and the lid is opened further with both stoppers of the main body and lid engaged, the lid stopper will move the main body stopper. There is a danger of getting over and partially exposing the inside of the main unit.
[0007]
In order to prevent the stopper part from being damaged when the lid is opened and the lid body stopper part from climbing over the main body stopper part, the thickness of both stopper parts has conventionally been increased, To prevent damage and exposure inside the body. However, considering that the thickness of both stoppers is sufficiently increased and that the amount of engagement between both stoppers is sufficiently increased, the size of the main body increases, which is a major obstacle in designing a compact system. I was
[0008]
Then, this invention aims at solving the said problem, and aims at improvement of the hinge part strength and commercial value of a cooker, and aims at providing the cooker which enables compact design of a main body.
[0009]
[Means for Solving the Problems]
According to the cooking container of the first aspect of the present invention, the stopper member is arranged, a gap is provided, and when the lid is opened, the stopper member comes into contact with the main body stopper portion, so that the opening member is opened by the opening means. The force of the lid can be absorbed by the stopper member, preventing the force from being applied to the stopper portion, and the durability of the hinge portion can be improved.
[0010]
According to the cooking container of the second aspect of the present invention, when the lid is opened, the brake means for urging the force so as to prevent the lid from being provided is provided. By making it smaller, the force applied to the main body stopper portion when the lid is opened can be reduced, and the durability of the hinge portion can be further improved.
[0011]

The control system of the cooking device will be described with reference to FIG. In the figure, reference numeral 71 denotes a control means comprising a microcomputer or the like, which is a heating coil for heating the bottom of the pan 11 during rice cooking and keeping the temperature based on the respective temperature information from the pan temperature sensor 21 and the lid temperature sensor 47. 16, a cord heater 26 for heating the side of the pot 11, and a lid heater 46 for heating the lid 5. In particular, the control means 81 of this embodiment mainly controls the heating coil 16 based on the temperature detected by the pan temperature sensor 21 to manage the temperature of the bottom of the pan 11, and mainly controls the temperature detected by the lid temperature sensor 47. The lid heater 46 is controlled to control the temperature of the radiator plate 37 and thus the inner lid 41. The control means 71 includes, as a function in a control sequence of a program stored in its own storage means (not shown), a cooking control means for controlling cooking and heating of the object to be cooked. The rice cooking control unit 72 includes a rice cooker control unit 72 that cooks and heats an object to be cooked in the cooker 11, and a heat retention controller 73 that keeps and heats the rice in the pan 11 to a predetermined heat retention temperature during the heat retention.
[0024]
Reference numeral 75 denotes a heating coil driving unit including a high-frequency inverter circuit that receives a control signal from the control unit 71 and supplies a predetermined high-frequency current to the heating coil 16. Separately from this, on the output side of the control means 71, a lid heater driving means 76 for receiving the control signal from the control means 71 and driving the lid heater 46 so as to heat the radiator plate 37 and the inner lid 41 is provided. And a code heater driving means 77 which receives a control signal from the control means 71 and turns on the code heater 26. At the time of rice cooking by the rice cooking control means 72 and at the time of thermal insulation by the thermal insulation control means 73, the temperature of the pan 11 is detected by the pan temperature sensor 21 and the lid temperature sensor 57, so that the heating coil 16 heats the bottom of the pan 11; The heating of the side of the pan 11 by the heating unit 26 and the heating of the lid 5 by the lid heater 46 are performed. After the rice cooked by the rice cooker control means 72 is completed and the food in the pot 11 is cooked as rice, the process automatically shifts to the heat retention by the heat retention controller 73 and the temperature detected by the pot temperature sensor 21 is reduced to the temperature. The rice is kept at a predetermined temperature (about 70 ° C. to 76 ° C.) by adjusting the heating of the pot 11 by the heating coil 16 and the code heater 26 based on the temperature.
[0025]
In particular, the supplementary description of the heating by the code heater 26 is as follows: after the rice is cooked, the temperature of the rice drops from about 100 ° C. to about 73 ° C .; Heat is radiated from the metal plate 29 to the space of the gap 30 between the lid 5 and the insulated pot main body 1 to suppress cooling due to invasion of outside air from the gap 30 and to heat the flange portion 14 of the pot 11. Further, even during the period of reheating the rice at the time of keeping the temperature, the flange portion 14 of the pan 11 is heated by the code heater 26 so as to prevent moisture generated by heating the rice from condensing on the upper inner surface of the pan 11. ing.
[0026]
Next, the operation of the above configuration will be described. When rice and water to be cooked are put in the pan 11 and the rice cooking by the rice cooking control means 72 is started, the heating coil 16 and the code heater 26 turn on based on the temperature detection of the bottom of the pan 11 by the pan temperature sensor 21. The bottom part and the side part of the pan 11 are heated, and the water temperature in the pan 11 is maintained at 45 to 60 ° C. for 15 to 20 minutes. After that, the pot 11 is strongly heated by the heating coil 16 to boil the food to be cooked. When the temperature of the bottom of the pan 11 becomes 90 ° C. or higher during the boiling heating, and the temperature of the lid 5 is stabilized at 90 ° C. or higher, it is assumed that the inside of the pan 11 is in a boiling state, and the amount of heating is reduced as compared to before. It moves to the continued boiling heating. The fact that the temperature of the lid 5 is stabilized at 90 ° C. or higher is detected by the rate of temperature rise of the temperature detected by the lid temperature sensor 47. In this boiling detection, it can be confirmed from the pot temperature sensor 21 and the lid temperature sensor 47 that both the bottom of the pan 11 and the lid 5 have reached 90 ° C. or higher, and that the inside of the pan 11 has completely boiled. Can be accurately detected.
[0027]
When either the bottom of the pot 11 or the lid 5 has an unusually detected temperature of 120 ° C. or higher, the control unit 71 determines that there is some abnormality and reduces the heating amount in the rice heating. To stop all operations, or to shift to a spot to be described later, or to keep the temperature, thereby preventing abnormal heating. Conversely, while either the bottom of the pot 11 or the lid 5 has reached 90 ° C. or higher and a predetermined time (eg, 5 minutes) has elapsed, the bottom of the pot 11 or any of the lids 5 Is lower than 90 ° C., the pot temperature sensor 21 or the lid temperature sensor 47 in this low temperature determines that the temperature detection accuracy has deteriorated for some reason (dirt, inclination, poor contact, etc.). In the same manner, the amount of heating in rice cooking heating is reduced, and all operations are stopped.
[0028]
When the process shifts to the continuation of boiling, the rice cooking control means 72 starts the lid heating by the lid heater 46. The lid heating here is managed by the temperature detected by the lid temperature sensor 47 so that the temperature of the inner lid 41 becomes 100 to 110 ° C. Then, when a predetermined temperature rise occurs in the bottom of the pot 11, the cooking is detected and the process shifts to spots. During murara, the lid heater 46 is turned off by temperature control based on the temperature detected by the lid temperature sensor 47 to prevent dew on the inner lid 41 and to maintain a high temperature (98 to 100 ° C.) so that rice does not burn. The temperature of the bottom of the pan 11 or the side of the pan 11 is controlled so as to be maintained. The moth is continued for a predetermined time (15 to 20 minutes).
[0029]
When the temperature is maintained, the bottom and the lower side of the pot 11 are heated by the heating coil 16, and the temperature of the rice stored in the pot 11 is slightly higher than that of the rice stored in the pot 11. The temperature of the side of the pot 11 is controlled by the cord heater 26 so that the rice does not dry and a large amount of dew does not adhere. Rice is kept at 70-76 ° C. Even when the temperature is kept warm, if the pot temperature sensor 21 or the lid temperature sensor 47 is abnormally high or low on the contrary, the abnormality is detected and this abnormal heating is prevented.
[0030]

Is incorporated in the outer lid cover 38, and the outer frame 2 is engaged with the leaf spring before the lid stopper 87 comes into contact with the main body stopper portion 82 to obtain a braking effect. In this example, the lid brake 88 is engaged with the outer frame 2 before a stopper member 91 to be described later comes into contact with the main body stopper portion 82 so that a braking effect can be obtained.
[0034]
The upper end of the main body stopper portion 82 forms a free end, and the corresponding rear end of the lid stopper portion 87 forms a free end. Therefore, as described in the related art, the lid stopper portion 87 is 82. Therefore, a stopper member 91 is provided on the lid 5 separately from the main body stopper portion 82. The stopper member 91 has a locking portion 91A that locks to the main body stopper portion 82, and a gap 92 is provided between the locking portion 91A and the lid stopper portion 87. The stopper member 91 is provided on the outer cover 38 and may be connected to the outer cover 38 by a claw fitting. Alternatively, the stopper member 91 may be inserted into the outer cover 38 through the hinge shaft 4.
[0035]
A stainless plate material is used for the stopper member 91. By using stainless steel, durability and a predetermined strength are obtained, and even if steam in the pot 11 leaks and hits the stopper member 91, Rust can be prevented from occurring. The stopper member 91 is formed by bending a stainless steel plate into an L shape, and one end of the stopper member 91 serves as the locking portion 91A.

When the lid 5 is opened by a force other than the coil spring 31, the lid is opened by the main body stopper 82 and the lid stopper 87. Since the opening of the body 5 is regulated, the force of the lid 5 opened by the coil spring 31 is absorbed by the stopper member 91, and the force can be prevented from being applied to the lid stopper portion 87, and the durability of the hinge portion H is improved. Can be improved. Further, since the space volume of the hinge portion H is small and the stopper member 91 can absorb the force without sufficiently reinforcing the stopper portions 82 and 87 of the main body 1 and the lid 5, the durability of the hinge portion H is improved. Can be prevented, space can be saved, and a compact design can be achieved. Further, even if a force other than the coil spring 31 is applied to open the lid 5 with the lid 5 opened, the opening of the lid 5 is regulated by the main body stopper 82 and the lid stopper 87. In addition, it is possible to prevent the main body stopper portion 82 and the lid stopper portion 87 from getting over, to suppress the inside from being exposed, and to provide a product with high consumer value.

As described above, in the present embodiment, when the lid 5 is opened, the lid brake 88 is provided as lid brake means for urging a force in a direction which obstructs the urging force of the coil spring 31 as the lid opening means. Since the lid opening angle at which the lid brake 88 starts to be effective is smaller than the lid opening angle at which the main body stopper portion 82 and the stopper member 91 come into contact with each other, it is possible to reduce the force applied to the main body stopper portion 82 when the lid 5 is opened. As a result, the durability of the hinge portion H can be further improved. The angle shown in FIG. 3 is the lid opening angle at which the main body stopper portion 82 and the stopper member 91 contact.

FIGS. 4 and 5 show a second embodiment of the present invention. The same reference numerals are used for the same parts as those in the above-described embodiments without detailed description. In this example, as in the first embodiment, A stopper member 91 is provided on the lid stopper portion 87 of the outer lid cover 38, and the stopper member 91 is integrally provided with a lid brake means. The stopper member 91 is provided on the bearing portion 84 and has the locking portion 91A and an elastic sliding portion 93 in the lid opening / closing direction. The elastic sliding portion 93 is separated from a side surface 84M of the bearing portion 84. When the lid 5 is opened, the wall portions 83 located on the left and right sides of the main body stopper portion 82 come into contact with the oblique portion 94 so that the oblique portion 94 follows the side surface 84M when the lid 5 is opened. Sliding while being elastically deformed so as to cause a braking effect, the elastic sliding portion 93 is provided at the tip thereof with the locking portion 91A. Thereby, the stopper member 91 can not only restrict the opening of the lid 5 but also have a lid braking function.
[0039]
As described above, in this embodiment, the stopper member 91 is provided with the elastic sliding portion 93 serving as a lid brake, so that the stopper part 91 and the lid brake means are the same, thereby reducing the number of parts and improving the assemblability. , Cost is reduced, and an inexpensive design is possible.
[0040]
FIG. 6 shows a third embodiment of the present invention, in which the same reference numerals are used for the same parts as those in the above-described embodiments without detailed description thereof. In this example, the main body stopper 82 of the outer frame 2 A stopper member 101 having a substantially inverted U-shaped cross section is provided. The locking portion 101A of the stopper member 101 is disposed closer to the lid stopper portion 87 than the main body stopper portion 82 is. That is, the locking portion 101A is located at a position closer to the closed state of the lid 5 than the main body stopper 82 on the locus where the lid 5 opens. A gap 102 may be provided between the locking portion 101A and the main body stopper portion 82. The stopper member 101 is provided on the outer frame 2 and may be provided by being connected to the outer frame 2 by a claw fitting, or may be incorporated into the outer frame 2 through the hinge shaft 4.
[0041]
A stainless plate material is used for the stopper member 101, and durability and a predetermined strength are obtained by using stainless steel. Further, even if the steam in the pan 11 leaks and hits the stopper member 101, the occurrence of rust can be prevented. Further, the stopper member 101 may be formed of a metal component and may have the above-described structure, or may be formed of an elastic material such as rubber.
[0042]
As described above, in the present embodiment, when the stopper member 101 is disposed on the main body stopper portion 82 provided on the warming pot main body 1, and when the lid 5 is opened, the lid stopper portion 87 has a higher position than the main body stopper portion 82. Since the stopper member 101 comes into contact first, the force of the lid 5 opened by the coil spring 31 is absorbed by the stopper member 101, and the force can be prevented from being applied to the main body stopper portion 82. Can be improved. evidence
The present invention is not limited to the above embodiment, and various modifications can be made. For example, the shape and number of the stopper members can be appropriately selected.
