Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an outer container mounting structure for a cooking appliance such as a jar or a rice cooker.

(Prior Art) Conventionally, as the outer container mounting structure of this type of cooker, for example, Japanese Utility Model Application Publication No. 57-87614 and Japanese Utility Model Publication No. 59-87-
What is shown in Publication No. 31121 and the like is publicly known. That is, a circumferential groove is provided on the upper surface of a synthetic resin shoulder body provided at the upper end of a cylindrical outer wall plate, and a plurality of engagement holes are bored in the circumferential groove, while a plurality of engagement holes are bored inside the outer wall plate. The upper end of the bottomed cylindrical outer container to be fitted is bent into an inverted U shape to form a flange, and a plurality of claw pieces are provided on the lower end surface of the flange to secure the flange of the outer container. It is placed on the top of the inner jetty of the circumferential groove, and has a structure in which the claw piece is inserted into the engagement hole and bent.

(Problem to be solved by the invention) However, in the case of the structure described above, since the flange of the outer container is in contact with the top of the inner jetty of the circumferential groove of the shoulder body over the entire circumference, the temperature is low. There is a problem in that when it rises abnormally, the synthetic resin shoulder body undergoes thermal deformation and becomes unusable. In addition, when the outer lid of the container is opened and closed, water droplets adhering to the inner surface of the outer lid fall into the circumferential groove of the shoulder body, flow within the groove, and enter between the outer container and the outer wall plate through the engagement hole. However, there are problems such as having an adverse effect on electrical components.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a structure for mounting an outer container of a cooker that can prevent thermal deformation of the shoulder body and the intrusion of water droplets.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a device that fits into the circumferential groove of a synthetic resin shoulder body provided at the upper end of the cylindrical outside wall board. In the outer container mounting structure of a cooker, which is attached by fitting a flange provided at the upper end of the bottom cylindrical outer container, a plurality of engagement holes are provided in the circumferential groove of the shoulder body, and a plurality of engagement holes are provided in the circumferential groove of the shoulder body, and a plurality of engagement holes are provided in the vicinity of both sides of the engagement holes. A dam part is provided, and a protrusion having an inclined surface is formed on both sides of the lower edge of the engagement hole, and the flange part of the outer container is bent into an inverted U shape, and the flange part is formed under the flange part. A plurality of L-shaped claw pieces are provided on the end face, the lower end face of the flange of the outer container is placed on the upper surface of the dam part of the shoulder body, and the claw pieces are inserted into the engagement holes to remove the protruding claw pieces. The tip is bent and locked onto the slope of the protrusion.

(Example) Next, an example of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a rice cooker to which the present invention is applied, which roughly consists of an outer wall plate 1, a shoulder body 2, an outer lid 3, an outer container 4, and an inner container 5.

The outer wall plate 1 has a cylindrical shape with a bottom to which a bottom body 6 with legs is joined, and forms the outer shape of the main body of the rice cooker.

The shoulder body 2 is made of synthetic resin and is formed into a ring shape as shown in FIG. is provided with leg portions 9 and claw portions 10 for attaching the outer wall board 1. In addition, on the bottom surface of the circumferential groove 8, as shown in FIGS. 4 to 6, slit-shaped engagement holes 11 into which claw pieces 16 of the outer container 4, which will be described later, are fitted are provided at three equally spaced positions on the circumference. It is perforated. A dam part 12 for damming the circumferential groove 8 is provided at a position close to the upper edge of the engagement hole 11, and a protrusion having an inclined surface is provided at a position close to both sides of the lower edge of the engagement hole 11. 13 are provided.

As shown in FIG. 6, this shoulder body 2 has its legs 9 fitted into the folded upper end of the outer wall board 1,
It is designed to be attached by locking its upper end with a claw part 10.

The outer cover 3 has an inner cover 14 that covers the inner container 5 inside, and is attached to the outer wall board 1 via a hinge (not shown) so that it can be opened and closed.

The outer container 4 is a cylindrical container with a bottom, and as shown in FIG. Pieces 16 are provided at three equally spaced positions on the circumference.

To attach and fix the outer container 4 to the shoulder body 2, as shown in FIG.
is inserted into the circumferential groove 8 and the lower end of the flange 15 is placed on the upper surface of the dam 12. Then, as shown in FIG. 7, the claw pieces 16 protruding downward from each engagement hole 11 are sequentially
If the outer container 4 is bent and slid up on the inclined surface of the protrusion 13 and locked, the outer container 4 is fixed to the shoulder body 2 without wobbling. Note that the claw piece 16 is adapted to be retained on the protrusion 13 even if it is bent in the opposite direction to that shown in FIG.

The heating plate 17 is attached to the bottom of the outer container 4, and the inner container 5 is fitted into the outer container 4.

In the rice cooker with the above configuration, the tip of the flange 15 of the outer container 4 is in contact with the upper surface of the dam 12 of the circumferential groove 8, and since the contact area is small, the shoulder body can be used even when the temperature rises abnormally. 2 will not be thermally deformed. Further, even if water droplets fall and accumulate in the circumferential groove 8 of the shoulder body 2, the weir portion 12 prevents them from flowing into the engagement hole 11.

In the above embodiment, the claw piece 16 of the outer container 4 is
Although it is provided in the shape of a letter, it is not limited to this, and may be bent on both sides to form a T-shape. Furthermore, it goes without saying that the present invention can be applied to cooking utensils in which the outer wall plate or outer container is not limited to a cylindrical shape but is rectangular.

(Effect of the invention) As is clear from the above explanation, according to the invention, a part of the lower end surface of the outer container comes into contact with the upper surface of the dam of the shoulder body, and since the contact area is small, abnormalities occur during cooking. Even if there is a significant temperature rise, there is no risk of thermal deformation of the shoulder body and it is safe.

In addition, water that has accumulated in the circumferential groove of the shoulder body is prevented from flowing into the engagement hole by the weir and does not enter between the outer wall board and the outer container, which may cause electrical components to malfunction. Instead, the product value improves. moreover,
Since the tip of the claw piece is locked on the inclined surface of the protrusion,
The outer container has the effect of being securely fixed to the shoulder body without wobbling.
