Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an outer lid locking structure for a rice cooker used in general households.

Conventional structure and problems thereof Conventionally, in this type of rice cooker, as shown in Fig. 1, a ring-shaped upper frame 2 is inserted into the upper part of the main body 1. A hinge part that supports the lid 3 and provides a hinge effect is integrally provided, and a hook receiver 5 that locks a seesaw-type hook lever 4 provided on the outer lid 3 on the opposite side projects to the outside of the main body 1. Generally, the hook cover 6 was integrally provided with a hook cover 6 covering the outside. However, in this configuration, since the hook cover 6 is provided so as to protrude outward from the shape of the main body 1, the hook cover 6 is absolutely necessary to avoid an unsightly appearance. The parts became large, the appearance lost its simplicity, and there were also problems in terms of effective use of space in the installation location of the product itself.

Purpose of the Invention The present invention solves these conventional problems and provides a rice cooker that has an outer lid locking holder to achieve a simple appearance and space saving without providing any protrusion outside the main body shape. It is something to do.

Composition of the Invention The rice cooker of the present invention has a main body with a double structure, a pot housed in the main body, and an outer lid that covers the upper opening of these, and an upper frame forming the upper part of the main body with the double structure. An outward convex wall is provided on the top surface to a height equal to or higher than the outer circumferential surface of the upper frame and equal to or lower than the top surface of the upper opening flange of the pot to be stored in the main body,
This convex wall is provided with an outwardly projecting protrusion for locking the hook, and a position on the outer lid side corresponding to the hook receiving part on the main body side formed by the convex wall provided on the upper frame and the protrusion for hook system locking is provided. At least a concave portion is formed so that the hook receiving portion on the main body side is accommodated within the container body when the outer lid is closed.

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

2 and 3, reference numeral 10 denotes a double-structure main body formed of an upper frame 14 connecting a body 12 and a protective frame 13 at the upper part through a heat insulating material 11;
15 is a pot housed in the main body 10; 16 is an outer wall that covers the upper opening of the main body; one side is supported by the upper frame 14 of the main body 10, and the other side is connected to the main body by a seesaw type hook 17 provided on the outer lid. 10 upper frame 14
It is adapted to be latched to a hook receiving portion 18 on the main body side provided in the main body.

4 and 5 show details of the hook receiving portion 18 on the main body side.

In FIGS. 4 and 5, reference numeral 19 denotes an upwardly protruding wall provided on the upper surface of the upper frame 14, and this protruding wall 19 has a U-shape, and has an outwardly protruding hook on the inside thereof. A stop protrusion 20 is provided. Convex wall 1
The upper surface of 9 is equal to or higher than the outer circumferential upper surface 14a of the upper frame 14, and is lower than the upper surface of the pot flange, as is clear from FIG. At least a recess 21 is provided at a corresponding position on the outer lid side, and the outer lid 16
When the hook 17 of the main body is locked to the hook locking convex part 20 of the hook receiving part 18 of the main body, the hook receiving part 18 of the main body is stored inside the container, and the hook engaging part 18 of the main body is stored in the container. The engaging portion of the hook cover is set to operate between the locking projections to release the outer lid from engagement.

22 is a soup receiving guide groove on the upper surface of the upper frame.

To explain the operation of the above structure, water and rice are placed in a pot housed in the main body, and the bottom of the pot (not shown in the drawings) is heated by a heater to cook the rice.

The steam generated during rice cooking is exhausted to the outside, but some remains as a soot on the underside of the outer lid. This is explained in the instruction manual, etc., and this is important because it allows excess moisture attached to the surface of the rice to escape.

At this time, the soup adhering to the lower surface of the outer lid drips onto the pot and the upper surface of the upper frame when the outer lid is opened.

Generally, a drip tray is installed at the bottom of the hinge part for the dripping of the soup on the upper surface of the upper frame, and a guide groove is provided on the upper surface of the upper frame so that the soup flows in this direction. I try not to. This type of soup flow is not necessarily used on a horizontal floor surface, so if a hook receiving part is provided on the top of the upper frame, this dripping soup will collect in the hook receiving part and will be difficult to clean. This uneven hook receiving part is difficult to handle, and in order to prevent soup from flowing into this part, the upwardly protruding wall on the top of the upper frame is shaped like an outward U-shape, and the surface is the same as the outer circumferential surface of the upper frame. Or, make it higher than that and form a wall with the guide groove for the flow of soup on the upper surface of the upper frame, and provide a hook locking protrusion on the inside of this wall to lock the hook of the outer lid during cleaning. It is possible to prevent the occurrence of defects.

In addition, these are provided on the upper surface of the upper frame, and at least a recess is formed on the outer lid at a position corresponding to the hook receiving portion on the main body side so that the outer lid can be closed. It is completely stored inside the main body and the outer lid, so there is no protrusion outside the vessel, giving it a clean appearance.At the same time, the fact that there is no protrusion is also very effective from the point of view of effective use of kitchen space. It is advantageous in that it can be placed in close contact with a wall, etc., and has a great effect in saving space at the place where the container is installed.

In addition, providing a hook receiving part on the top surface of the upper frame,
It is also located closer to the outer lid, and the hook provided on the outer lid protrudes from the bottom surface of the outer lid, but this protrusion can be reduced, and the outer wall can be opened to make it easier to use when serving rice, etc. There are also advantages in handling, such as not getting stuck, and since the height of the convex wall is equal to or lower than the top surface of the pot flange, it does not interfere with the operation of pouring rice.

Effects of the Invention As is clear from the above embodiments, the rice cooker of the present invention has an upward convex wall on the upper surface of the upper frame constructed at the upper part of the main body having a double structure, which is equal to or higher than the height of the outer peripheral surface of the upper frame. The hook receiving part has a height equal to or less than the height of the top surface of the pot flange, and has an outward hook locking protrusion on the convex wall, and the position corresponds to the hook receiving part on the outer lid side. By providing at least a recess in the outer cover so that the hook receiving part is housed within the main body and the outer cover when the outer cover is closed, there is no need to provide a protruding part from the main body, resulting in a simple appearance and space-saving miniaturization. It can be measured. Further, since the convex wall is equal to or smaller than the upper surface of the pot flange, the convex wall does not get in the way when serving rice, and a decrease in operability can be prevented.
