DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an induction heating type rice cooker, and more particularly to a storage structure of a pot.

[0002]

2. Description of the Related Art In an induction heating type rice cooker, a brim portion of a pot is placed on an inner peripheral edge of a shoulder portion of the rice cooker body,
A slight gap is provided between the pot and the protective frame of the storage section. This gap is to prevent the heat of the heated pot from being directly transmitted to the protective frame.

However, in the above configuration, since the heat of the pot is directly transmitted to the shoulder of the rice cooker body through the collar of the pot, it is necessary to form the entire shoulder with a heat-resistant resin, which causes an increase in cost. Become.

[0004] For this reason, there is a method in which a separate small heat-resistant part is attached to the shoulder at several places to suppress an increase in the cost of the shoulder, but in this case, the work of attaching the separate heat-resistant part is required. Required, which also causes an increase in cost.

Accordingly, the present invention provides an induction-heated rice cooker in which the heat of the pot is not transmitted directly to the shoulder portion without increasing the cost by using a handle necessary for attaching and detaching the pot. The purpose is to provide.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a rice cooker body in which a pot is removably stored in a pot storage section, and a brim portion of the pot is attached to the rice cooker body. In the induction heating type rice cooker configured to support the pot by being placed on a shoulder portion, a handle made of a heat-resistant resin having a required length along the collar portion is attached to two opposite sides of the collar portion, And the pot is placed on the shoulder through a part of the pan.

The ratio of the handle length to the pot diameter can be selected in the range of 0.4 to 0.6.

[0008] In the induction-heated rice cooker having the above-described structure, the heat of the pot is insulated by the handle made of a heat-resistant resin, so that heat conduction to the shoulder is reduced. Therefore, it is not necessary to use a heat-resistant resin for the shoulder, and ordinary resin is sufficient.

[0009] Further, by adopting a configuration in which a restricting portion for controlling the radial movement of the pan is provided on the contact surface with the shoulder of the handle, the pan can be stabilized. Furthermore, by adopting a configuration in which an elastic body is integrally provided on the contact surface with the shoulder of the handle and the above-mentioned regulating section is provided on the elastic body, stabilization of the pan is achieved and generation of the sound of the pan is generated. Can be prevented.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a rice cooker body 1 of an induction heating rice cooker.
And a pot 3 removably stored in the storage section 2 of the rice cooker main body 1 and a lid 4 attached to the rice cooker main body 1 so as to be openable and closable.
Consisting of

A protective frame 6 is provided on the inner peripheral surface of the shoulder 5 of the rice cooker main body 1.
The inside of the protection frame 6 is the storage section 2 of the pot 3. The induction heating coil 7 is mounted on the lower surface of the protection frame 6. A recess 8 having a required length along the housing 2 is provided on the shoulder 5 at two opposing locations outside the housing 2.

On the other hand, as shown in FIG. 1 and FIG.
Collar 9 protruding outward over the entire circumference of the opening
, And the handle 11 is attached to two opposing positions of the collar portion 9. The handle 11 is made of a required heat-resistant resin (for example, PA
[Nylon], PET (polyethylene terephthalate)), and has an arc shape along the arc of the collar portion 9.

The handle 11 is formed on a mounting base 12 in contact with the lower surface and the outer peripheral surface of the collar portion 9, a grip portion 13 projecting outward from the mounting base 12, and an outer end upper surface of the mounting base 12. And an inverted L-shaped finger protection portion 14. The finger protection portion 14 is inserted into the outer peripheral surface of the collar portion 9 and is fixed to the collar portion 9 by a screw 10 screwed from the lower surface of the mounting base 12 (FIG. 3 (a)).

The lower surface of the mounting base 12 serves as a contact surface 15 with the shoulder 5, and the contact surface 15 is provided with an inverted L-shaped restricting portion 16 which matches the upper end surface of the shoulder 5 and the corner of the inner peripheral surface. Provided. Further, the grip 13 protrudes above the recess 8 of the shoulder 5. The overhang width is as shown in FIG.
It is set so as not to protrude from the outer peripheral surface of the lid 4. Grasp
The end of the part 13 is open to the external space.

The pot 3 is supported by the contact surface 15 of the handle 11 resting on the upper surface of the shoulder 5 inside the recess 8. Therefore, if the length B of the handle 11 is too short, the support of the pot becomes unstable. Also, if the handle 11 is too long, the circumferential length of the recess 8 is correspondingly increased and the heat insulating property is deteriorated. Therefore, the length B of the handle 11 is made larger than the diameter A of the pot 3 in consideration of these points. Thus, the ratio is set to be in the range of 0.4 to 0.6.

The shape of the restricting portion 16 of the handle 11 is formed on the outer surface of the contact surface 15 so as to fit into the upper surface of the shoulder 5 and the corner of the recess 8 as shown in FIG. You may.
Further, as shown in FIG. 3C, an elastic member 17 such as rubber may be integrally provided inside the contact surface 15 and the restricting portion 16 may be formed on the elastic member 17. With such a configuration, the movement of the pan 3 is restricted, and at the same time, the micro vibration of the pan 3 due to the induction heating is reduced.

The induction-cooked rice cooker according to the embodiment is as described above. As shown in FIG.
5 is placed on the upper surface of the shoulder 5 in the recess 8, and the rice is cooked with the lid 4 covered. The heat of the pot 3 due to the heating is attenuated and reduced at the mounting base 12 of the handle 11. For this reason, since the material of the shoulder portion 5 does not require heat resistance, a general synthetic resin (for example, PP [polypropylene], ABS) can be used. Further, the pan 3 is restricted from moving in the horizontal direction by the restricting portion 16, and swinging in the front-rear direction of the pan 3 with the contact surface 15 as a fulcrum is also regulated, and the pan 3 is stably supported.

[0019]

As described above, according to the present invention, the pot is placed on the shoulder of the rice cooker via a part of the handle attached to the pot, so that the heat of the pot is insulated by the handle. Be relaxed. For this reason, a relatively low-cost general synthetic resin can be used for the entire shoulder portion of the rice cooker main body, and the manufacturing is easy, so that the cost of the product can be reduced.

By properly selecting the length of the handle, a stable pot can be supported without impairing the heat insulation.

Further, by providing a restricting portion on the contact surface with respect to the shoulder of the handle, the movement of the pot can be prevented, and further stabilization can be achieved. In addition, an elastic body such as rubber is provided on the contact surface. By providing the above-mentioned regulating portion on the elastic body,
It is possible to prevent the sound of the pot from sounding during heating.
