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.

BACKGROUND OF THE INVENTION In recent years, the overwhelming majority of rice cookers and electronic jars that have rapidly become popular in households are so-called handy types.

A feature of this type of device is that the upper opening surface of the main body, which has an inner container that can be stored in a detachable manner, is covered by a lid that is pivoted on one side and can be opened and closed.

Further, in this configuration, a hook lever is provided on the lid body on the opposite side of the pivot part, and a hook lever that can be operated to engage the lid body and the main body, and a hook lever for opening/closing the lid in the direction of connecting the hook lever and the pivot part.
and a bridge handle for carrying instruments.

Problems to be Solved by the Invention 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 downside is that modern rice cookers not only cook rice, but also keep the rice warm for long periods of time and function as traditional rice bowls, so the lids are opened and closed most often when serving the rice. There was a problem in that the rice scoop or bowl had to be picked up again after the lid was opened.

Another disadvantage is that it requires a large handle on the top of the lid, which hinders the realization of the desire to simplify and compact the design of rice cookers, which is related to the increase in the number of various cooking utensils in recent years. I can say that I am there.

In view of the above-mentioned drawbacks, the present invention has been developed to solve the following problems:
To provide a rice cooker in which the lid of the appliance can be opened and opened with a one-touch operation even when holding a rice scoop in the right hand and a bowl in the left hand.

Means for Solving the Problems In order to achieve the above object, the rice cooker of the present invention has a main body having a planar shape having a linear portion on at least one side, and a lid body hinged to the linear portion of the main body. An elastic member such as a spring that constantly applies a lid opening force to the lid body and a damper spring that relieves the opening operation of the lid body are provided near the hinge portion, and a damper spring that relieves the opening operation of the lid body. The apparatus is constructed by providing an engagement device that engages and locks the device body when the body is closed, and also includes an operating section that releases the engagement of this engagement device.

Function: With this configuration, when it is desired to open the lid, the lid can be opened easily by simply pressing lightly on the operating portion, and the lid can be smoothly moved to the next operation.

EXAMPLE Hereinafter, an example of the present invention will be described 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 bottomed cylindrical body, and this body 1 constitutes an instrument main body 4 by combining an inner frame 2 provided inside and an upper frame 3 at the top. Further, the inner bottom of the inner frame 2 has a heating element 6 for heating rice cooking and a thermostat 6 for detecting the completion of rice cooking, and is further provided with a removable rice cooking pot 7.

Reference numeral 8 denotes a lid body, which has an inner lid 9 and is pivoted to one side of the instrument main body 4, that is, a linear portion, by a shaft 11 at a hinge portion 1o. Further, a spring 12 is provided in association with the shaft 11, which is always biased in the direction of opening the lid 8, and a circle is provided near the shaft portion to alleviate the V and tsuku when the lid 8 is opened. An arc-shaped damper 13 and a damper spring 14 are provided.

On the other hand, a hook lever 16 for engaging the lid 8 in the closed state is attached to the shaft 16 on the inside of the instrument main body 4, and is located on the side substantially opposite to the hinge portion 1o that pivotally supports the lid 8. The hook lever 16 is attached using a biasing spring 17, and a portion of the hook lever 16 faces outside from the side wall of the instrument main body 4 as an operating section 18 to be pressed.

On the side of the lid body 8 facing the hook lever 16.

A hook 19 is attached to a shaft 20 and a spring 21, and an auxiliary operation part 22 faces outside through a recess 23 provided on the top surface of the lid body 8. In addition, 24 is a grip part for transportation formed with two recesses facing the side wall of the instrument main body 4, and 25 is a leg.

Next, the operation of the rice cooker configured as described above will be explained.

First, as shown in FIG. 1, when the lid 8 is in the closed state, the upper end of the hook lever 16 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, by pressing the operating portion 18, the seven levers 16 and the hooks 19 are disengaged, 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 addition, in this embodiment, the instrument body 4 may be
When it is difficult to press the operating part 18 on the side, the auxiliary operating part 22 on the side of the lid 8 is also configured to disengage the hook lever 16 and the hook 19 to automatically open the lid.

In this way, according to this embodiment, even if both hands are occupied,
The lid body 8 can be opened automatically by simply pressing the operating part 18 or the auxiliary operating part 22, which is convenient to use.

Moreover, since the lid 8 is automatically locked by pressing a portion of the lid 8 against the biasing force of the spring 12, the closing operation can be easily performed. Furthermore, since the rice cooker as a whole can eliminate the handle, it has a very beautiful appearance.

Although the present embodiment has been described using a square rice cooker, one side is provided with a hinge portion 1o, a spring 12 that biases the lid 8 in the opening direction, and a damper spring 14 that relieves the opening operation of the lid 8. If only one side is made straight, the other sides may be arcuate, which can be easily provided.

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 the lid, unlike conventional hand-held rice cookers. An operating section is provided, and an elastic member for biasing the lid in the opening direction and a damper spring for relaxing the opening operation of the lid are provided near the hinge located on the opposite side of the operating section, and the instrument body The planar shape of the rice cooker has a linear portion on at least one side, and the hinge portion is provided on the linear portion, so that a robust rice cooker with a simple structure and automatic opening/closing operation can be obtained. .

Especially when serving rice, there is a rice scoop in the right hand.

Even if you are holding a bowl in your left hand, you can easily serve the bowl 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 it is also possible to place other items on the top when the appliance is not in use. This has the effect of realizing effective use of space.
