Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pressure cooker that is improved so that the lid can be easily opened and closed, and also that a heat retention function can be easily added after pressure cooking. It is something.

Conventionally, in so-called bayonet engagement type pressure cookers, the flanges of the pot and lid have a notch and a locking part, and the two are fitted and rotated to engage, and the cooker is opened by releasing the engagement. The drawback is that it is difficult to find a place to place the lid, and a structure in which one side of the lid is pivoted to the top of the main body, like an electronic jar, has been required. On the other hand, there was a demand for a pressure cooker that also has a heat retention function, but since the pressure cooker is not pressurized when it is kept warm, temperature differences tend to occur inside the pot. A structure that is simple and easy to handle has been desired.

The present invention has a configuration that meets the above-mentioned conventional requirements, and the configuration will be explained below based on the drawings in which the present invention is implemented in an electric pressure cooker with a heat retention function.

In the figure, reference numeral 1 denotes a main body with a double structure, which has a heat insulating material 2 in between and a heating element 3 at the inner bottom.
Reference numeral 4 denotes a pot removably mounted on the heating element 3, and the upper opening of the pot is closed by an inner lid 6 with a ring-shaped packing 5 interposed therebetween. The flange portion of the upper opening of the pot 4 has a cutout portion 24 and a locking portion 2 as shown in FIGS. 1 and 3.
3 are provided alternately, and on the other hand, notches 26 and locking portions 25 are also provided alternately on the flange portion of the inner lid 6.
A bayonet-shaped engaging portion is provided for closing the lid by rotating the inner lid 6 so as to engage the locking portions 23 and 25 of the inner lid 6.

Reference numeral 7 denotes an outer cover which thermally covers the outer surface of the inner cover 6, and is provided with a cover heating element 8 located on the inner cover on the lower surface, and a handle 9 for opening/closing operation is provided at the upper part. The inner cover 6 is constructed to be able to be freely attached to and removed from the center of the lower surface of the outer cover as needed, and both covers can be operated as a unit by means of a handle 9.

Reference numeral 10 denotes an upper frame located at the upper edge of the main body 1, which is formed into a ring shape, and is held at two opposing positions by a pair of slide holders 11 and 11' attached to the main body. ing. Further, a hinge portion 12 is provided on a portion of the upper frame 10 above an extension portion 13 for pivotally supporting the lid so that the lid can be opened and closed, and a hinge portion 15 is provided on one side of the outer lid 7 by a shaft 14. It is connected with. Further, the slide holder 11 is provided with a stopper 16 against which the extension portion 13 of the upper frame comes into contact. As shown in FIG. 7, a pair of stoppers 16 are provided at both ends of the slide holder 11, and limit the range of rotation of the lid which can be rotated together with the upper frame 10. Further, a protruding part 10' held by a slide holder 11' is provided on the other side of the upper frame 10, and the upper frame 10 is connected to the slide holders 11, 11', the extension part 13 of the upper frame 10, and the protruding part 10'. is held in

Reference numeral 17 denotes a cord that electrically connects the lid heating element 8 to the main body side, which is led out to the outside via bushings 18 and 19, and has a flexible structure to facilitate horizontal rotation of the lid and smooth opening/closing operations. .

Reference numeral 20 denotes a handle for the appliance provided on the upper part of the main body 1, and 21 controls cooking together with an operation part 22 containing a control circuit using a heat-sensitive sensor.

Next, the lid opening/closing operation in the above configuration will be explained.

Storing the pot 4 with cooking ingredients prepared inside the main body 1,
When setting the lid, when the handle 9 is closed in the solid line position shown in FIG. 3, the notches and locking portions of the pot 4 and the inner lid 6 can be engaged with each other.

Thereafter, when the handle 9 is moved to the position shown in the dashed line, the inner cover attached to the bottom of the outer cover also rotates.
The flanges of the pot and inner lid are locked, forming a pressure vessel inside. In addition, during the above rotation, the axis 1
The upper frame 10 that is continuous with 4 is also the slide holder 1.
1 and rotates.

When closing the lid, conversely, by rotating it to the solid line position in Figure 3, the lid body including the inner lid can be opened and closed freely around the shaft 14, and when closed, it is in a position slightly beyond the vertical position. It is held in

Although the above description has been made regarding an embodiment that also has a heat retention function, the present invention is not limited to this embodiment. By pivoting at one location on the horizontally sliding upper frame, the initial objective of significantly improving opening and closing operations can be achieved.

As is clear from the above explanation, according to the structure of the present invention, the opening and closing operations of the lid of the pressure cooker can be made extremely easy, and if the double lid method is used, the heating part can be placed on the lid and The configuration is easy and an excellent pressure cooker can be provided.

Claims (1)

[Scope of Claims] 1. A cylindrical main body, a heating element provided inside the main body, a pot located above the heating element and detachably provided, and an upper opening of the pot via packing. The pot and the lid have a structure in which the pot and the lid are rotated by fitting a notch provided in a flange portion and a locking portion to each other to form a sealed pressurized container. This pressure cooker is equipped with an upper frame that can be rotated only in the horizontal direction on the upper edge of the main body, and one side of the lid is pivoted to a part of the upper frame so that it can be opened and closed. 2. The lid body is composed of an inner lid and an outer lid that are detachable from each other, and the inner lid and pot form a sealed pressurized container by rotating the notch and locking portion provided in the flange of each other. At the same time, the outer lid covers the inner lid,
The pressure cooker according to claim 1, wherein the container is kept warm by a heating element installed in the upper part of the inner lid, and is pivotally supported on the upper frame.
