BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cooker having a structure in which an opening force is applied to the lid by a spring.

0003

[Prior Art] Conventionally, in this type of rice cooker, a heater is installed internally and a lid is pivotally mounted on the main body that houses a pot heated by the heater, and the lid can be opened and closed. A person can open it by lifting it by hand. In recent years, for example, a torsion coil spring has been incorporated into the pivoting portion of the lid, thereby applying an opening force to the lid, thereby eliminating the need for the manual lifting operation of the lid, or reducing the operating force. A similar method is being considered.

0004

[Problem to be Solved by the Invention] However, in the case of the device conceived as described above, it is not possible to check the installed state of the built-in torsion coil spring without disassembling the lid as a whole, which is not easy. However, if the device is installed in an uncertain state, it may not function properly, or if an abnormality occurs, it cannot be easily inspected or repaired.

The present invention has been made in view of the above-mentioned circumstances, and therefore, its purpose is to provide a structure in which the lid can be opened automatically or easily opened, and the installation state of the spring can be easily confirmed. We offer rice cookers that you can get at.

[Configuration of the invention]

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an outer frame constituting the outer shell of the main body, an upper frame constituting the upper end surface of this outer frame, and an inner frame inside the main body. An inner frame, a pot built into the inner frame, a lid that covers the top opening of the pot, a hinge receiver formed on the upper frame to rotatably support the lid, and a spring that provides an opening force to the lid. The invention is characterized in that it is equipped with a cover that covers the spring from the outside.

[0008]

[Operation] According to the above means, by simply removing the cover, the spring can be seen and its installed state can be confirmed.

[0009]

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. First, in FIG. The upper end surface is constituted by the upper frame 3. Further, as shown in FIG. 2, the main body 1 is equipped with an inner frame 4, and this inner frame 4 is equipped with a pot 5 and a heater (not shown) for heating the pot. Reference numeral 6 denotes an inner lid placed over the opening on the top surface of the pot 5. Further, 7 is a hinge receiving portion formed on one side of the upper frame 3 on the right side in the drawing, and 8 is a hooking portion formed on the other side on the left side of the upper frame 3 in the drawing. On the other hand, 9
is a lid that covers the opening on the top surface of the pot 5, and in detail, this is made up of an outer lid 10 and an inner lid 11, and a heat insulating material 12 etc. is arranged between the two lids. . In addition, on the outer surface, the main body part 1 of the handle part 13 extends in the radial direction from one place on the outer periphery of the outer lid 10 to one place on the opposite side in the shape of a bridge.
4 are integrally formed, and a hinge piece 15 (see FIG. 4) is also integrally formed at one end of the handle main body 14, and this hinge piece 15 is connected to the hinge receiver. the hinge shaft 16 from the side.
By passing the lid 9 through the main body 1, the lid 9 as a whole is pivotally mounted on the main body 1 so that it can be rotated to open and close. 17 is a hanging plate for the tension coil spring which will be described later, 18 is a hinge cover,
The hanging plate 17 is positioned inside the hinge receiving part 7, and then the hinge cover 18 is attached to the upper frame 3 together with the hanging plate 17 by screws 19 so as to cover the hinge receiving part 7 and the hanging plate 17. . On the other hand, 20 is a lid locking device provided on the opposite side of the hinge piece 15 of the lid 9, and this also has a base member 21 and a lock lever 22, of which the base Member 21
is placed on the other end of the outer cover 10 and fixed with a screw 23 passed from below the inner cover 11, and then the middle part of the lock lever 22 is rotatably pivoted to the base member 21 by a shaft 24. A compression coil spring 25 is interposed between the lock lever 22 and the base member 21, and the spring force causes the claw portion 2 at the tip of the lock lever 22 to close.
6 is engaged with the hook part 8 to lock the lid 9 in the closed state. Here, the handle portion 13 is the main body portion 1
In addition to 4, it has a cover 27 that closes the open part on the top surface, and as a whole, as shown in FIG. 3, it has a hollow shape.
A spring, for example, a tension coil spring 28 is disposed inside the cover 27 along its longitudinal direction before the cover 27 is attached, and one end of the spring 28 is hooked to the hanging plate 17. is connected to the main body 1 via the hanging plate 17, and the other end is connected to the lid locking device 20.
The lid 9 is connected to the lid 9 via the base member 21 by being hooked to the base member 21 of the lid 9.
It gives a liberating power to Then, in this state, cover 27
By installing the spring 28, the spring 28 is covered from the outside.

Therefore, in the case of this embodiment configured as described above, when the lid 9 is held in the closed state by the lid locking device 20, the lock lever 22 is pressed and the claw portion 26 is hooked. When the lid 9 is released from the closed state by removing it from the portion 8, the lid 9 rotates around the hinge shaft 16 by the opening force applied from the spring 28 and opens automatically. This eliminates the need for manual lifting of the lid 9 or reduces the operating force, making it very convenient.

[0011] While the same convenience can be obtained, especially in this embodiment, by simply removing the cover 27, the spring 28 can be seen and its installed state can be confirmed. Therefore, unlike the conventional case where the lid 9 had to be completely disassembled, it can be easily confirmed. Therefore, it is possible to cover the spring 28 after the spring 28 is securely installed, and its normal function can be ensured. In addition, the spring 28 and its installation condition can be easily inspected and repaired when an abnormality occurs in its function.

FIG. 5 shows a different embodiment of the present invention, in which one end of the tension coil spring 28 is connected to, for example, the above-mentioned hanging plate 17 via a linear member 29 such as a wire or string, and then to the main body. By doing so, one end of the handle 13 can be conveniently connected without any problem even when the shape of the handle 13 becomes complicated or the inside thereof becomes narrow. You can get used to it.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but may be implemented with appropriate modifications within the scope of the gist.

[0014]

Effects of the Invention As is clear from the above, the present invention has an outer frame that constitutes the outer shell of the main body, an upper frame that forms the upper end surface of this outer frame, an inner frame that is installed inside the main body, and an inner frame that is installed inside the inner frame. A lid that covers the top opening of the lid, a hinge receiver formed on the upper frame to rotatably support the lid, and a spring that applies an opening force to the lid. It is equipped with a cover that covers both sides, so that the lid not only opens automatically or can be opened easily, but also has a structure that makes it easy to check the installation state of the spring. It has the excellent effect of being able to.
