Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the structure of a rice cooker that is used on a daily basis in general households.

Conventional configurations and their problems In recent years, the overwhelming majority of the external configurations of rice cookers and electronic jars, which have rapidly become popular in general households, are so-called "indie-type" configurations.

The feature of this type of device is that it is equipped with an inner container that can be stored in a detachable manner, and that the upper opening surface of the main body is covered by a lid that is pivotally supported on one side and can be opened and closed.

Furthermore, in this configuration, a hook lever is provided on the lid body on the opposite side of the pivot portion, and a hook lever is provided for engaging the lid body and the main body, and a bridge bridge for opening/closing the lid and for transporting instruments is provided in the direction connecting the hook lever and the pivot portion. It is equipped with a state-of-the-art system.

The advantage of the rice cooker configured as described above is that it is mobile, as it can be transported and the lid can be opened and closed continuously. However, the drawback is that the lid is opened and closed most often when serving the rice, as it is not only used for cooking rice these days, but also functions as a traditional bowl because it can keep warm for a long time. There was a problem where I had to pick up the rice scoop 7 or the bowl again.

Another drawback is that it requires a large cooker on the top of the lid, which hinders the realization of the desire for a simpler and more compact rice cooker design in conjunction with the recent increase in the number of various cooking utensils. I can tell you something.

OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks, the present invention seeks to provide a rice cooker in which the lid of the appliance can be opened with a single touch even when holding a rice scoop in the right hand and a bowl in the left hand, such as when serving rice. It is something.

Structure of the Invention In order to achieve this object, the rice cooker of the present invention has a lid pivotally supported on one side of the main body, and the lid has an elastic member such as a spring that constantly applies the opening force. It is configured by providing a locking device that engages and locks the main body when the lid is closed, and an operating section that releases the locking device.

With this configuration, as soon as the lid is opened, it can be easily opened by simply pressing lightly on the operating section, and the next operation can be smoothly carried out.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an external perspective view of a square rice cooker according to the present invention, and FIG. 2 is a partially sectional side view of the square rice cooker with the lid opened.

In the figure, reference numeral 1 denotes a cylindrical body with a bottom, which is combined with an inner frame 2 provided inside and an upper frame 3 at the top to form an instrument main body 4.

The inner bottom of the inner frame 2 has a heating element 5 for heating rice cooking and a thermostat 6 for detecting the completion of rice cooking, and is further provided with a detachable rice cooking pot a.

A lid body 8 has an inner lid 9 and is pivotally supported on one side of the main body 4 by a shaft 11 at a hinge portion 1o. Further, a spring 12 is provided in relation to the shaft 11 and is always biased in the direction of opening the lid 8, and an arc-shaped damper 13 is provided near the shaft to reduce the shock when the lid 8 is opened. and a damper spring 14 are provided.

On the other hand, inside the main body 4 on the opposite side from which the lid 8 is pivoted, a hook lever 15 for engaging the lid 8 in the closed state is attached using a shaft 16 and a biasing spring 17, Lever 1
A part of the main body 4 faces the outside from the side wall of the main body 4 as an operating section 18 to be operated by pressing.

On the side of the lid 8 facing the hook lever 15, a hook 19 is secured by a shaft 20 and a spring 21, and an auxiliary operation section 22 faces outside through a recess 23 provided on the top surface of the lid 8. I'm here. Note that 24 is a grip portion for transportation formed with two recesses facing the side wall of the main body, and 25 is a leg.

The operation of the rice cooker configured as above will be explained below.

First, as shown in FIG. 1, when the lid 8 is in the closed state, the upper end of the hook lever 15 and the lower end of the hook 19 are engaged, and are in a locked state against the biasing force of the spring 12.

When opening the lid 8, the hook lever 15 and the hook 19 are disengaged by pressing the operating portion 18, and the lid 8 is automatically opened by the biasing force of the spring 12. In addition, especially at the final stage of this opening operation, the damper spring 14 allows the lid to be quietly stopped from being opened.

In this embodiment, depending on the usage condition, the operating section 1 on the main body 4 side is
8 is difficult to press, the hook lever 16 and the hook 19 can be automatically opened by disengaging the hook lever 16 and the hook 19 using the auxiliary operating section 22 on the lid body 8 side.

As described above, according to this embodiment, even if both hands are occupied, the lid 8 can be opened automatically by simply pressing the operating section 18 or the auxiliary operating section 22, making it easy to use. The closing operation can also be easily performed by pressing a part of the lid 8 against the biasing force of the spring 12 and automatically locking it. Furthermore, since the handle can be eliminated from the rice cooker as a whole, it has a very beautiful appearance.

Effects of the Invention As described above, the present invention does not have a handle on the top surface of the lid body for disengaging and opening/closing operations, unlike the conventional rice cooker of the Indian type. Since the rice cooker is provided with a portion and an elastic member provided on the lid body to apply the opening force, a rice cooker that can be automatically opened and closed can be obtained.

Particularly when serving rice, even if you are holding a rice scoop in your right hand and a bowl in your left, you can easily do this by simply pressing the operation part lightly.

In addition, since there is no need for a large bridge-like handle on the top of the appliance body as in the past, it is possible to design a compact rice cooker, and when the appliance is not in use, it is also possible to place four other rice cookers on the top, which saves space. This has the effect of making it possible to make effective use of space.
