Description

[Detailed Description of the Invention] The present invention relates to a container mounting structure for an electric cooker.

Conventionally, the container mounting structure for electric kettles has fixed the main body ring and container with screws, which increases the number of parts and assembly man-hours. After installing the locking piece and inserting the locking piece into the fitting hole of the main body ring,
Since the locking piece is bent to lock the container,
There were drawbacks such as difficulty in assembling the container and damage to the container during the work of bending the locking piece.

The present invention has been made to eliminate the above-mentioned drawbacks, and includes a fitting hole formed on the inner periphery of the main body ring at the upper end of the container, and a fitting piece that mates with the fitting hole and has a locking opening. Furthermore, by providing a protruding locking piece on the main body ring that engages with this locking hole, the container can be fixed with a one-touch operation of inserting the locking piece into the locking hole, reducing the number of parts and making assembly easier. It makes work easier, prevents damage during assembly, improves assembly efficiency, and reduces costs.Furthermore, the container can be securely fixed because the bottom edge of the container is held with leg metal fittings. It is an object of the present invention to provide a device that can prevent positional displacement even if thermal deformation of a main body ring occurs and can improve reliability.

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

The structure of the embodiment is as shown in the figure. Reference numeral 1 denotes a main body ring made of thermoplastic resin, which engages an outer frame 2 made of a printed steel plate and a drawn container 3. Reference numeral 4 designates fitting holes formed at two or more locations on the inner periphery of the main body ring 1. Reference numeral 5 denotes a mating piece, which is provided at the upper end of the container 3 and is mated with the mating hole 4,
It also has a locking opening 6. 7 is a locking piece that is integrally formed with the main body ring 1 and is connected to the fitting hole 4.
It is installed near the connecting piece 5 of the container 3.
It is formed into a protruding shape that engages with the locking opening 6 of the. The inner pot 8 is removably placed on the container 3, and the inner bottom of the container 3 is equipped with a hot plate 9 for heating the inner pot 8. Reference numeral 10 denotes a bottom, which includes a leg fitting 11 fixed to the outer bottom surface of the container 3, and a thermosetting resin foot 12 extending from the outer bottom surface of the bottom 10.
The outer frame 2 is sandwiched between the main body ring 1 and the bottom 10 and fixed with a set screw 13. Reference numeral 14 denotes an outer lid that covers the upper opening of the main body, and is fixed to the main body ring 1 so as to be openable and closable. Reference numeral 15 denotes an inner lid, which is provided at the upper opening of the inner pot 8.

The operation of this embodiment will be explained based on the above configuration. When setting the container 3 with the leg fittings 11 already attached to the main body consisting of the bottom 10 outer frame 2 and the main body ring 1, insert the fitting piece 5 of the container 3 into the fitting hole 4 of the main body ring 1 while inserting the fitting piece 5 into the main body. When the container 3 is lowered, the protruding locking piece 7 engages with the locking opening 6 of the engagement piece 5, and the container 3 is fixed to the main body ring 1. Since the container 3 is installed in one place, the container 3 can be stably attached to the main body ring 1 without any wobbling. Next, the thermosetting resin foot 12 on the lower surface of the bottom 10 and the leg fittings 11 are screwed together with screws 13 to securely fix not only the upper side but also the lower side of the container 3.

As described above, according to the present invention, since the container is provided with a locking opening and the main body ring is provided with a locking piece, it can be fixed with a single touch, reducing the number of parts such as screws, and eliminating confusion during assembly, making assembly work easier. It is easy to connect, and also prevents damage to the main body ring and container when mating, improving assembly efficiency and reducing costs. Also, since the bottom side of the container is held with leg fittings, it is easy to fix the container. Even if thermal deformation of the main body ring occurs, positional deviation can be prevented and reliability can be improved.
