Abstract

PURPOSE:To present a cover having a steam port prevented from giving a scald even if one comes in contact with it and prevented from being removed even if any force is applied to it, by forming the circulating course of steam, with the penetration hole of a lower plate, a packing, the rib of the upper plate of low heat conductivity, and the penetration hole of the upper plate. CONSTITUTION:On the lower surface of an upper plate 5a showing the appearance section of a cover 5, by a circular internal rib 5c, external rib 5d set surrounding the periphery of an upper plate hole 5b, and a lower plate 4, a steam plate packing 7 is retained between the ribs and the plate 4, and a steam port for exhausting steam 8 to be generated under cooking by the upper plate hole 5b, the steam plate packing 7, and a lower plate hole 4a, outside a cooker is formed. Besides, the shape of the upper plate 5a is also complicated, and the lower surface is required to be provided with the internal rib 5c and the external rib 5d, and so they are molded with the use of resin material. On composition in this manner, the steam port section is not made hot as the material of the upper plate 5a is the resin material of a low heat conductivity, and is integrally molded with the upper plate, and so even if a force is applied to the steam port section, it is not removed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking device such as an electric jar rice cooker used in general households, and particularly to a lid mechanism thereof.

BACKGROUND OF THE INVENTION Conventionally, this type of cooking appliance has had a structure as shown in FIG. In FIG. 3, 51 is the main body of the cooker, 62 is a heating element located inside, and the upper part is a pot 53 for storing food.
is placed. A lid 55 having a lower plate 64 that seals the inside of the pot 63 is pivotally supported on one side by a hinge shaft 56 on the upper part of the main body 51 . A lid heater 57 is attached to the upper surface of the lower plate 64 to keep food warm.

Further, a through hole 54a is formed in the lower plate 54, and a through hole 54a is formed in the top plate 55.
A packing 59 defining a passage hole for discharging steam 68 so as to correspond to the through hole 54a is attached to the upper end of the panokin 59, and a steam plate 60 is attached to the upper end of the panokin 59. still,
65b is a handle.

As a result, the steam 58 generated in the pot 53 during cooking is
The steam is discharged to the outside air through the steam plate vanokin 59 and the steam plate 60.

FIG. 4 is an enlarged view of essential parts of 60 parts of a conventional steam plate.

As the lower plate 54, anoremi material is often used because it conducts the heat of the lid heater 67 well. The reason why the steam plate 6o is a separate unit from the lower plate 54 is because it is an exterior component and needs to be plated, so that steam does not enter into the lid 65 due to the space between it and the lower plate 64. The steam plate Punkin 59 was used.

Problems to be Solved by the Invention In such a conventional configuration, since the steam plate 6o is a metal component, it is heated by the steam 58 during cooking to a temperature of about 80°C.
The temperature reached ~90 degrees Celsius, and even after the steam stopped coming out, there was a risk of burns if people touched it. Further, when the steam plate 6o is pushed from above, there has been a problem in that the steam plate 60 comes off from the steam plate bunokin 69.

The present invention solves this problem, and provides a lid for a cooker that does not pose a risk of getting burned if touched during cooking, and does not cause any defects in appearance.

Means for Solving Problem UU In order to solve the above problems, the present invention provides a container-shaped main body;
A heating element provided inside the main body, a pot placed on top of the heating element, a lower plate located on the upper part of the main body and sealing the inside of the pot, and the lower plate'&-cover and lower surface. an upper plate formed of a low thermal conductivity material having a circular rib protruding from a part thereof; and a packing held between the lower plate and the rib; This is a cooking device in which a steam flow path is formed by a through hole connected to a panking.

Function: According to this configuration, the steam distribution path is formed by the through holes in the lower plate, the packing, the ribs in the upper plate, and the through holes in the upper plate, but the upper plate, which conducts the heat of the steam, is made of a resin with low thermal conductivity. It does not get hot because it uses parts. Also, in terms of appearance, since the steam outlet is integrally molded with the upper plate, it is possible to obtain a structure that is strong against external forces and does not spoil the appearance.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2.

In the figure, 1/I'i cooking device main body, 2 is a heating element fixed inside, and a pot 3 for storing food is placed on top of the heating element. At the top of the wooden body 1, there is a lower plate 4 that seals the inside of the pot 3.
A lid 5 having a lid 5 is fixed to the lid 5 so as to be openable and closable. Further, a heater 6 for keeping warm is attached to the upper surface of the lower plate 4.

FIG. 1 shows an enlarged view of the essential parts of the present invention. On the lower surface of the upper plate 5IL representing the external appearance of the lid 5, there are circular inner ribs SC provided around the upper plate hole 5b, and outer ribs SC. The rib 5d and the lower plate 4 sandwich the steam plate vanokin 7. The circular inner rib 5C mainly serves to press the steam plate hack 7 against the lower plate 4, and the circular outer rib 5d serves to temporarily fix the steam plate hack 7 when assembling the lid 5. . The lower plate 4 has a hole 4 in the lower plate corresponding to the steam plate banokin 7! L is provided, and the upper plate hole 5b, the steam plate packing 7, and the lower plate hole 4a form a steam port for discharging steam 8 generated during cooking to the outside of the vessel. Further, the upper plate 5a has a complicated shape and requires the provision of inner ribs 50 and outer ribs 5d on the lower surface, so it is molded using a resin material.

With the above structure, the upper plate 6a is made of a resin material with low conductivity, so the steam port does not get hot, and since it is integrally formed with the upper plate, there is no problem even if force is applied from above. do not have.

Effects of the Invention As described above, according to the present invention, since steam is no longer emitted after cooking, it is not obvious that the main body is hot, and even if a person touches the steam vent, there is no risk of unsafe conditions such as burns. In addition, even if force is applied to the steam vent from above, there is no problem of the steam vent coming off like in the past, resulting in an untidy appearance, and the effect of providing a high quality lid. There is.
