BACKGROUND TECHNOLOGY A conventional lid device for an electric cooker of this type has a fifth
The structure was as shown in the figure. That is, in FIG. 5, 1 is a lever, and by pressing the lever push button 2, the lower end of the lever 1 is disengaged from the cooking device main body 5, and by opening the lid 3, the contents are released. Can be taken out. 4 is a round pot into which the contents are placed. A push button 2 is attached to the lever 1, and the lever 1 is bent so that both sides thereof face each other to form a side wall 1a, and a bearing plate 6 is installed inside the both side walls 1a. It is provided so as to have a surface parallel to the face walls 1a, 1a. In addition, one end of the inner surface of the bearing plate 6 is attached to the lever 1.
A spring 7 is provided so that the other end is in contact with the bearing plate 6, and the center of the spring 7 is supported,
A shaft 8 is provided which passes through a hole in the side wall 1a of the lever 1 and a hole in the side surface of the bearing plate 6, and the spring 7 allows

Reference numeral 10 denotes a protrusion provided on the outer periphery of the cylindrical cooking device main body 5, which is configured to engage with and disengage from the lever 1. Reference numeral 11 denotes a cover on the lever 1 side, and the upper inner surface is sloped to make it easier for the tip of the lever 1 to enter.

As described above, conventionally, the protrusion 10 is provided on the outer periphery of the cooking device main body 5, and this
and a cylindrical cooking device body 5 that supports this round pot 4.
This is to make the gap between the lid body 3 as small as possible, light weight, and space-saving.
Generally, the lever 1 has a disc shape similar to the cooking device main body 5, and the engaging/disengaging portion of the lever 1 is provided on the outer periphery of the cooking device main body 5.

Problems to be Solved by the Invention However, with this type of structure, the cylindrical cooker body 5 is provided with a protrusion 10, which may cause pain if it hits the dining table or touches the body when carried. It was also difficult to use. In addition, a cover 11 and the like to protect the protruding portion 10 is required, which increases the number of parts and requires a complicated shape, resulting in a long assembly time.
Furthermore, the presence of the protrusion 10 makes the design unsightly and gives priority to function. For this reason, although it has been desired to have a configuration in which the lid 3 can be engaged and detached without installing any parts outside the cooking device main body 5, a new problem has arisen. Fig. 4 is a partial cross-sectional view of one embodiment of the present invention, and the details of the parts will be described later. It is necessary to provide a through hole in the However, the lid of an electric cooker that has a heat retention function is generally equipped with a lid heater 12 (see Fig. 5) and is normally used in an energized state. When a through hole is provided in the lower part of the body, steam from the food being cooked enters through the hole, and if condensation occurs, the insulation is no longer maintained, which is dangerous. Conventional electric cookers were designed to engage and disengage from the outer circumference of the cooker main body 5 using a lever 1 provided on the outer circumference of the lid 3.
There is no problem, but this invention prevents steam from entering through the through hole provided at the bottom of the lid, and
It is an object of the present invention to provide a configuration in which no protrusion is provided on the outside of the cooking device main body.

Means for Solving the Problems In order to solve the above problems, the present invention provides a through hole through which the lever passes through the lid cover that covers the lower surface of the lid body, and also takes into account the change over time due to heat. A rib is provided around the hole, and a protrusion covering the outer periphery of the rib is provided on the lid.

Effects According to the above configuration, when assembling the lid and the lid cover, the ribs provided on the lid cover and the protrusions provided on the lid serve as guides, so assembly is facilitated.
After assembly, the protrusion on the lid side covers the outer periphery of the rib on the lid cover side. In addition, since the lid cover is provided on the inner surface of the lid, the protrusion of the lid faces downward, while the ribs of the lid cover face upward, and in this case, the through hole through which the lever passes rises. Because the steam is heated,
This vapor will rise along the ribs of the lid cover and be guided to the top surface of the lid. On the other hand, the protrusion of the lid protrudes downward, so when steam tries to flow into the inside of the lid, the steam will head downwards, but this is because the heated and lighter gas flows through the air. It goes against the laws of nature as it descends. Therefore, by providing a sufficiently wide through hole for the lever to pass through, the steam can be
This prevents the light from reaching the lid heater provided inside the lid.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 to 4, 20 is a cooking device main body, and 20a is a protrusion provided on the top of the cooking device main body 20. Reference numeral 21 denotes a lid, which is provided on the cooking device main body 20 so as to be openable and closable. 21
a and 21a are a pair of protrusions provided on the lid 21 and protruding toward the cooking device main body 20 side. Reference numeral 22 denotes a lever, and this lever 22 has a hole 22a on one end side that can be engaged with and detached from the cooking device main body 20 side, and the other end side is operated by pressing. The hole 22a engages with and disengages from the protrusion 20a. 23 is a spring, this spring 23
has a repulsive force when the lever 22 is pressed.
Reference numeral 24 denotes a shaft that connects the lid 21 and the cooking device main body 20, and the lid 21 rotates around the shaft 24.

Reference numeral 25 denotes a lid heater, which is attached by adhesive to a heat sink 26a fixed to the lid cover 26, and generates heat when energized. The lid cover 26 is provided with a through hole 26a through which the lever 22 passes, and a rib 26 is provided around the through hole 26a.
b. The protrusion 21a is provided so as to cover the outer periphery of the rib 26b. Reference numeral 27 denotes a handle, which is fixed to the top surface of the lid body 21 with screws 28, 28. Numeral 29 is a screw for fixing the lid cover 26 and the lid 21. 30 is a handle cover that covers the lever 22, handle 27, etc. 30a is a hole through which the knob 22b of the lever 22 passes. In this embodiment, the cooking device main body 20
The lid body 21 and the like have a rectangular shape when viewed from above, and the handle cover 30 and the handle 27 are provided diagonally on the cooker body 20.

31 is a pot to put the food to be heated, and this pot 31
is formed into a cylindrical shape with a bottom, and this pot 31 is round when viewed from above, and if the cooking device main body 20 is square, it is easy to provide the engagement/disengagement structure of the lever 22 diagonally.

As is clear from the above explanation, since the cylindrical pot 31 is placed inside the rectangular cooking device main body 20, the locking/disengaging structure for the lever 22 does not need to be provided on the outer periphery of the cooking device main body 20, and can be placed at the corner. The cover 11 of the conventional example is not required. Furthermore, when the lid body 22 is opened, steam rises along the ribs 26b, but the heated steam further moves upward and is discharged to the outside through the hole 30a of the handle cover 30. Further, even if the cooker main body and the lid are circular, the above configuration is possible if dimensions are taken into consideration.

Effects of the invention As described above, according to the invention, a through hole through which the lever passes is provided in the lid cover that covers the lower surface of the lid, and a rib is provided around the through hole, and a rib is provided around the through hole. Since the lid is provided with a protrusion that covers the outer periphery, the steam that enters through the through hole will not reach the lid heater inside the lid, making it safe.
Moreover, since the ribs and protrusions serve as guides, assembly is not only easier, but also the number of parts can be reduced.Furthermore, since there are no protruding parts to the outside of the cooker body, electric cooking is easy to use. It is possible to provide equipment.
