Detailed Description
(insight underlying the present disclosure)
The present inventors have conducted intensive studies to further suppress deformation of the vicinity of the hinge portion, and have obtained the following findings.
The pressure type rice cooker cooks rice by pressurizing a pot. In the pressure cooker, since the pressure in the pot is higher than the atmospheric pressure, a strong pressure is applied to a portion of the lid body located above the pot, so that the portion of the lid body is lifted. At this time, an upward force is applied to the hinge portion to which the lid body is attached, and the vicinity of the hinge portion is easily deformed.
In order to suppress deformation of the vicinity of the hinge portion, it is conceivable to provide a reinforcing member separately in a portion that is likely to be deformed. However, in this case, the reinforcing member is increased in size, which leads to an increase in manufacturing cost. Further, since a wide space is required for providing the reinforcing member, the degree of freedom of design is limited.
On the other hand, when the pressure in the pan is higher than atmospheric pressure, a downward force to press the pan is also generated. After intensive research, the present inventors have found the following structure: a hinge reinforcing member connected to a hinge shaft is extended to a lower side of a flange portion of a pot, and the hinge reinforcing member is directly or indirectly brought into contact with a lower surface of the flange portion. According to this configuration, the downward force applied to the pan is received by the hinge reinforcing member, and the downward force is applied to the hinge portion by the hinge reinforcing member, whereby the upward force applied to the hinge portion can be reduced. As a result, deformation of the vicinity of the hinge portion can be suppressed. Further, according to this structure, the reinforcing member can be prevented from being enlarged. Further, according to this structure, the reinforcing member can be reduced in weight. Further, according to this structure, the structure of the reinforcing member can be simplified. Further, according to this configuration, the manufacturing cost can be reduced. Further, according to this configuration, it is possible to improve the degree of freedom in design due to a reduction in installation space. Based on this new finding, the present inventors have completed the following invention.

The hinge connection portion 22 is a portion connected to the hinge portion H1. The hinge connection portion 22 includes a vertical plate portion 22a, a pair of hook portions 22b, and a pair of connection portions 22 c. The pair of hook portions 22b are provided so as to face each other with the vertical plate portion 22a interposed therebetween. Each hook 22b is configured to be suspended on the hinge shaft 2C. The vertical plate portion 22a and the hook portion 22b are connected by a connecting portion 22 c. The vertical plate portion 22a and the connecting portion 22C are disposed on a vertical plane parallel to the hinge axis 2C. The hook 22b is disposed on a vertical plane orthogonal to the hinge axis 2C. The coupling portion 22c is integrally formed with the hook portion 22 b.
The pot support portion 23 indirectly contacts the lower surface of the flange portion 5a via the upper frame cap 17. The pot support portion 23 is a portion that supports the pot 5 through the upper frame cap 17. In the present embodiment, the hinge reinforcing member 21 includes two pan support portions 23. The pan support 23 is box-shaped. The pot support portion 23 includes a support surface 23a that receives the load of the pot 5. That is, the load of the pan 5 is dispersed to the entire support surface 23 a. The support surface 23a is provided with a notch 23b into which the shaft portion 17a of the upper cap 17 is inserted.

The rear end of each vertical plate 24b is connected to the hook 22 b.
Fig. 9 is a schematic cross-sectional view showing the vertical pressure applied to the lid body 2, the pot 5, and the hinge portion H1 in the rice cooking process. In fig. 9, the cut surface is made different with a broken line DL as a boundary in order to easily understand the positional relationship among the lid body 2, the flange portion 5a of the pot 5, the hinge portion H1, and the hinge reinforcing member 21. Note that the cover 2 is only shown in the frame portion, and the entire description is omitted.
As shown in fig. 9, in the rice cooking step, a pressure equal to or higher than the atmospheric pressure (for example, 2.0 atmospheres) is generated in the pot 5 in the radial direction from the center of the pot 5. At this time, since the upper portion of the pot 5 is opened, a strong pressure P1 is applied to the portion of the lid body 2 located above the pot 5, so that the portion of the lid body 2 is lifted. Thereby, an upward force P2 is applied to the hinge portion H1 to which the lid body 2 is attached. On the other hand, a strong pressure P3 is applied to the pan 5 in a pressing manner. Thereby, a downward force P4 is applied to the flange portion 5a of the pan 5.
In the pressure cooker of the present embodiment, the hinge reinforcing member 21 is connected to the hinge shaft 2C and extends to below the flange portion 5a of the pot 5. According to this configuration, the downward force applied to the flange portion 5a of the pan 5 is received by the hinge reinforcing member 21, and the downward force is applied to the hinge portion H1 via the hinge reinforcing member 21, whereby the upward force applied to the hinge portion H1 can be reduced. As a result, deformation of the vicinity of the hinge portion H1 can be suppressed. Further, according to this structure, the reinforcing member can be prevented from being enlarged. Further, according to this structure, the reinforcing member can be reduced in weight. Further, according to this structure, the structure of the reinforcing member can be simplified. Further, according to this configuration, the manufacturing cost can be reduced. Further, according to this configuration, it is possible to improve the degree of freedom in design due to a reduction in installation space.
Further, according to the pressure cooker of the present embodiment, the hinge reinforcing member 21 includes a plurality of pot supporting portions 23 (one example of the first and second pot supporting portions of the present disclosure). According to this structure, the hinge reinforcing member 21 contacts at a plurality of positions of the flange portion 5a of the pan 5, and the load applied to one pan support portion 23 can be reduced.
Further, the pressure cooker according to the present embodiment includes an upper frame cap 17 (an example of the elastic member of the present disclosure), and the upper frame cap 17 is disposed between the pot support portion 23 of the hinge reinforcing member 21 and the flange portion 5a of the pot 5. According to this structure, for example, generation of metal dust due to contact between the pan support portion 23 of the hinge reinforcing member 21 and the flange portion 5a of the pan 5 can be suppressed.
Further, according to the pressure cooker of the present embodiment, the pot support portion 23 of the hinge reinforcing member 21 has the support surface 23a that receives the load of the pot 5. According to this structure, the load applied to the pan support portion 23 can be dispersed as compared with a structure in which the load of the pan 5 is received by points or lines.
Further, the pressure cooker according to the present embodiment includes the upper frame reinforcing member 13, and the upper frame reinforcing member 13 is disposed below the upper frame 12 to reinforce the upper frame 12. The hinge reinforcing member 21 is attached to the upper frame reinforcing member 13. With this configuration, the deformation of the hinge reinforcing member 21 can be suppressed by the upper frame reinforcing member 13, and the deformation of the portion near the hinge portion H1 can be further suppressed.
In the hinge reinforcing member 21, the distance between the hinge connecting portion 22 and the pan supporting portion 23 is preferably small. Accordingly, the torque force applied to the hinge reinforcing member 21 can be reduced, and the downward force P4 applied to the flange portion 5a of the pan 5 can be more reliably applied to the hinge portion H1.
The present disclosure is not limited to the above embodiments, and can be implemented in various other embodiments. For example, in the above-described embodiment, the hinge reinforcing member 21 has a step in the vertical direction between the support surface 23a of the pan support portion 23 and the lateral plate portion 24a of the coupling portion 24, but the present disclosure is not limited thereto. For example, as shown in fig. 10A and 10B, the coupling portion 24 of the hinge reinforcing member 21 may have a beam portion 24 c. Beam portion 24c extends from below hinge portion H1 to below flange portion 5a of pan 5. The shape of the vertical cross section of beam portion 24C parallel to hinge axis 2C may be inverted in the vertical direction. The front end of beam portion 24c may be configured as a support surface 23a of pan support portion 23. With this structure, deformation of the hinge reinforcing member 21 can be further suppressed.
In the above embodiment, the pan support portion 23 of the hinge reinforcing member 21 indirectly contacts the flange portion 5a of the pan 5 through the upper cap 17 inserted into the notch portion 23b of the support surface 23a, but the present disclosure is not limited thereto. For example, as shown in fig. 11A and 11B, the pan support portion 23 may have a claw portion 23d instead of the support surface 23a and the cutout portion 23B. Claw portion 23d protrudes upward from the front end portion of beam portion 24c in front. The claw portion 23d is flat plate-like in shape. The upper end of the claw portion 23d may be directly in line contact with the flange portion 5a of the pan 5. With this configuration, a portion of beam portion 24c can be bent, for example, to easily form claw portion 23 d.
Further, in the above embodiment, the hinge shaft 2C is fixed to the lid body 2. In the above embodiment, the hinge portion H1 provided at the upper rear portion of the rice cooker main body 1 rotatably holds the hinge shaft 2C. However, the present disclosure is not limited thereto. The lid body 2 may be rotatable about the hinge shaft. For example, the hinge shaft may also be fixed to the hinge portion H1. The lid body 2 may be held so as to be rotatable about the hinge axis.
Industrial applicability
The pressure cooker of the present disclosure can further suppress deformation of the vicinity of the hinge portion, and thus is useful not only for a household cooker but also for a commercial cooker and the like.
