Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the structure of the main body and pot of a square type rice cooker used in general households.

Conventional configurations and their problems In recent years, there has been a remarkable development of rectangular type kitchen products from the viewpoint of effective use of kitchen space and a comfortable external design suitable for system kitchens.

Under these circumstances, rectangular type rice cookers have been commercialized, but due to space saving and miniaturization, the size margin of the main body relative to the pot has become smaller, and one problem with this is that the rice cooker Difficulty in handling is mentioned.

This is a rice cooker that consists of a pot that can be stored freely in the main body and an outer lid that covers the top of the rice cooker.When the outer cover is opened, the upper flange of the pot appears on the top of the main body. Therefore, the shape of the main body relative to the upper flange of the pot has little margin in the vertical direction or in the rectangular planar shape, and for this reason, it is difficult to secure space for holding the pot flange, and there are handling problems when storing and removing the pot from the main body. It was hot.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a rectangular rice cooker having a structure that achieves both improved handling and operability, space saving, and miniaturization.

Structure of the Invention The rectangular rice cooker of the present invention has a rectangular main body with a double structure and a pot that can be stored in the rectangular body, and the curvature of the corner of the upper flange of the pot is larger than the curvature of the rectangular corner of the main body. By providing a concave portion at the corner of the upper part of the rectangular main body, including the position facing the pot outer periphery flange, a space is secured for fingers to enter at the bottom of the pot flange, improving the operability of storing and taking out the pot. It is something.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 to 4, reference numeral 1 denotes a rectangular main body with a double structure, and a body 2 and a protective frame 3 are connected at the upper part by an upper frame 4, with a heat insulating material 5 interposed therein.

Reference numeral 6 denotes a pot, which has a rectangular cylindrical shape with an opening at the top and can be freely stored in the rectangular main body. 7 is an outer lid for covering the upper openings of the square main body 1 and the pot 6, one of the corners of the square is supported by the upper frame 4 and the hinge shaft,
This shaft is used as a fulcrum shaft 8 to open and close the outer cover, and a hook lever 9 provided on the outer cover 7 locks into a hook receiver 10 provided on the upper frame 4, thereby closing the outer cover 7. I try to keep time.

FIG. 3 shows a view from above with the outer lid open, and the curvature R ₁ of the corner of the upper flange 6 a of the pot 6 is the same as the curvature R ₂ of the corner of the square main body 1. It is made larger than the core R, and as a result, there is a space between the rectangular main body 1 and the pot 6 in a triangular shape at the corner of the rectangular planar shape, and a recess 11 is provided on the upper surface of the upper frame 4 in this part. be.

FIG. 4 shows a cross-sectional view of the corner of the main body, and reference numeral 12 indicates the finger of the hand that holds the flange 6a to take out the pot 6 when the outer lid 7 is opened.

To explain the operation in the above configuration, the storage and removal of the pot 6 into and out of the rectangular main body 1 is performed using the flange 6a of the pot 6.
The rectangular main body 1 has a double structure with a heat insulating material 5 interposed inside it, but in order to save space, it is made of a material with a high heat insulating effect. The flange 6a of the upper opening of the pot 6 in particular widens toward the outer periphery, and there is little difference from the rectangular planar shape of the main body, making it easy to pull your fingers. There is little hanging space. In order to secure space for this, the curvature R ₂ of the corner of the rectangular body 1 is
On the other hand, by making the curvature R ₁ of the corner of the pot larger than the concentricity R, the difference in shape between the flange 6a of the pot 6 and the rectangular main body 1 becomes larger at the corner in the square plane shape, and there is less space for fingers. In addition, in the upper frame 4 that connects the body 2 and the protective frame 3 to form a double structure of the rectangular main body 1, the corner portion where the shape difference is provided includes a position facing the pot flange. By providing the recess 11, the flange 6 of the pot 6
It is now possible to create space at the bottom of a,
You can easily hook your fingers on it, and it has the effect of greatly improving the operability of storing and taking out pots.

Although the above embodiment has been explained with respect to a square main body and a square pot, shape differences in the square planar shape are caused by the relationship between the curvature R ₂ of the corner of the square main body and the curvature R ₁ of the pot flange located thereon. However, it is also possible to create a difference in shape by combining a square body and a round pot.In short, in order to create a difference in shape, the corner of the square body and the pot flange located therein, the shape of the pot flange The curvature of the corner is made larger than the curvature of the corner of the rectangular body and the concentric R.

Effects of the Invention As is clear from the above embodiments, the rectangular rice cooker of the present invention has a relationship between a corner of the rectangular main body and a corner of the pot flange located here, a curvature of the pot flange, a By making the curvature of the corner part larger than the concentric R and by providing a concave part at the corner part of the square body including the position facing the pot flange, fingers of the hand are not drawn to the flange part of the pot when storing and taking out the pot. You can secure hanging space and improve operability, and the space in other parts can be minimized both in the rectangular plan shape and in the vertical direction, without impairing operability. This allows for further space saving and miniaturization.
