Description

[Detailed description of the invention] Industrial application field The present invention relates to cooking appliances used in general households, and particularly to cooking appliances such as jar rice cookers that have a display unit with electronic components such as a display mounted on the lid. This invention relates to a lid device.

2. Description of the Related Art A conventional lid device for a cooker of this kind has a structure as shown in FIG. 4, as shown in, for example, Japanese Utility Model Application Publication No. 60-57323.

That is, in FIG. 4, 1 is a cooking device main body, a pot 2 is installed inside this cooking device main body 1, and a lid body 3 is provided so as to be openable and closable via a hinge mechanism. This lid 3 is composed of an outer lid 4, a lid cover 6 having an inner plate 5 attached to its inner surface, and a handle 7 provided on the outer lid 4. Reference numeral 8 denotes an engaging protrusion which is provided in a protruding manner on the inner plate 5. 9 is the inner lid,
It is engaged and held by the engagement protrusion 8. Reference numeral 10 denotes a lid heater, and this lid heater 10 is provided at the center of the inner plate 5, is biased by a spring or the like so as to come into contact with the inner cover 9, and is loosely inserted into the center hole of the inner plate 5. Reference numeral 11 denotes an operation section, which is provided on the lid 3. In the operation section 11, 12 is a waterproof wall erected on the inner plate 5, and the waterproof wall 12 allows electrical equipment to be placed inside the lid cover 6. It is formed by partitioning the chamber 13.
14 is a switch 15 for operation and a display 1 for display.
The circuit board 14 is housed in the electrical component chamber 13 and is fixed to a plurality of bosses projecting downward from the outer cover 4 with screws 18 or the like.

FIG. 5 shows another conventional example, in which reference numeral 21 denotes a cooking device main body, in which a pot 22 is installed. A lid 23 is provided at the upper opening of the cooking device main body 21 via a hinge mechanism so as to be openable and closable, and a board 25 equipped with circuit components such as switches is mounted on a display board 26 in a recess 24 on the upper surface of the lid 23. A display board unit 29 formed by being sandwiched between a display board case 27 and fixed with screws 28 is housed.

Problems to be Solved by the Invention However, in such a conventional configuration, in the conventional example shown in FIG. Since it is made of resin material that is easy to mold, it is deformed by the hot air of the steam that flows in.
As a result, there is a problem that a gap is created between the waterproof wall 12 and the outer lid 4, and steam flows into the electrical component room 13. As a result, dew condenses on the display 16, making the display invisible. There was a problem that the electronic component 17 would shoot out. Furthermore, if the display device is made into a unit as in the conventional example shown in FIG. 5, the above-mentioned problems can be addressed to some extent;
In this case, when water is poured from above, water enters between the display panel unit 29 and the lid 23, and the accumulated water turns into steam due to the hot air during cooking, resulting in an airtight seal. Even if the display board unit 29 is installed, it cannot be completely sealed, and if a gap occurs due to deterioration over time, steam will flow into the display board unit 29 and cause the above-mentioned problems. Ta.

This invention solves these problems,
Even if steam flows in during cooking or water splashes from the top, the steam will not flow into the electronic components such as the display, ensuring a safe and safe environment without condensation on the display or malfunctions such as shorts. An object of the present invention is to provide a lid device for a cooker.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an openable and closable external device that is pivotally supported on one side of the upper part of the cooker body and detachably engaged with the other side of the upper part of the main body. The lid and
A display unit is installed in the recess on the upper surface of the outer cover and houses a circuit board having electronic components such as switches and indicators inside. It is provided with rising ribs that correspond to the shape.

Effect According to the above configuration, since the display unit is installed in the recessed part of the upper surface of the outer cover, it is no longer affected by the inflow of steam into the outer cover.
Also, even if water is rising from the top, direct water inflow will
This can be prevented with the display unit alone, and the display on the top of the outer lid also prevents water from flowing in between the outer lid and the display unit, collecting on the bottom of the display unit, and turning into steam due to the heat during cooking. This can be prevented by a raised rib provided on the surface corresponding to the display unit and corresponding to the shape of the bottom surface of the display unit.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 3.

In the figure, 31 is a cooking device main body, and a pot 32 is removably installed inside this cooking device main body 31. Reference numeral 33 denotes a lid that is pivotally supported on one side of the top opening of the cooking device main body 31 so as to be openable and closable, and that covers the top opening. A lid cover 35 constitutes the lower surface. Reference numeral 36 denotes a handle portion provided on the upper surface of the outer lid 34, and the handle portion 36 is composed of a handle 37 forming the lower surface and a handle cover 38 covering the upper surface. 39 is a rising wall provided on the upper surface of the outer lid 34, and this rising wall 39 allows the outer lid 34 to have a recess 3 on the upper surface.
9a is formed. 40 is a display unit that houses a circuit board 44 having a switch 41 for operation, a display 42 for display, and electronic components 43. Reference numeral 45 denotes a display board constituting the upper surface of the display unit 40. On the surface of the display board 45, a film-like display sheet 46 is provided with openings provided at positions corresponding to the display 42 and the switch 41 of the display board 45. It is attached with double-sided adhesive tape, etc., so as to cover it. Further, a seat 47 for fitting into the outer cover 34 is provided at the lower part of the display unit 40, and is in contact with the outer cover 40 here. The outer lid 40 is provided with a raised rib 48 located inside the seat 47.

In the above configuration, as shown in FIG. 3, even if steam 49 enters between the outer lid 34 and the lid cover 35 for some reason, the display unit 40 is housed in the recess 39a on the upper surface of the outer lid. It is not affected in any way, and 50% of water is added from the top.
However, since a film-like display sheet 46 is attached to the top of the display unit 40,
The display unit 40 and outer cover 3
In order to prevent water from flowing into the space between 40 and 40, the display board Water will no longer accumulate between the unit 40 and the outer cover 34.

Effects of the Invention As is clear from the above embodiments, according to the present invention, even if steam flows into the outer lid due to some abnormality or water accumulates in the cooker due to abnormal use, the display unit on the top of the outer lid The rising ribs provided on the corresponding surfaces and corresponding to the bottom shape of the display unit can trap water on the outside of the display unit, preventing damage to the electronic circuit section due to water entering the display unit. The fogging phenomenon of malfunction of the shutter, control section, and dew condensation on the display section due to steam is eliminated, and as a result, a safe and high-quality cooker lid device can be provided.
