Description

[Detailed description of the invention] This invention relates to cookers such as a rice cooker, an electronic jar, a jar rice cooker that has both functions, and a pressure jar rice cooker that has full-scale pressure cooking and long-term heat retention functions. The purpose is to prevent heat radiation from the gap between the lower surface of the upper outer periphery of the pot and the upper surface of the inner periphery of the protective frame, to make it easier to take out the pot, and to prevent water, etc. from flowing in from the upper outer periphery flange of the protective frame. be.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A pressure jar rice cooker capable of keeping warm for a long time, which is an embodiment of the present invention, will be described below with reference to the accompanying drawings.

In the figure, 1 is a rice cooking heater, which has a through hole in the center. 2 is a protective frame having a through hole in the center of the bottom, a rice cooking heater 1 attached to the inner bottom, and a heat retaining heater 3 for keeping warm at the outer upper part. 4
5 is a heat-sensitive device that passes through a through hole in the protective frame 2 and is fixed to a through hole in the rice cooking heater 1; 5 is an upper frame made of a ring-shaped resin material integrally molded with a hook portion and a hinge portion at the other end; A protective frame 2 is attached to the upper part of the periphery, and a body 6 constituting the outer shell of the main body is fitted to the lower part of the periphery. Reference numeral 7 denotes an outer lid made of a resin material with a handle part integrally molded, a support part that fits into the hinge part of the upper frame 5 is pivotally supported by a hinge shaft 8, and a hook lever 10 with a hook button 9 fixed to the other end is attached. Installation, upper frame 5
This locks the entire lid by fitting into the hook part of the lid. Reference numeral 11 denotes a heat dissipation plate that constitutes the lower surface of the lid, a lid heater 12 for heat retention is pasted on the upper surface, a holder packing 13 is attached to the central through hole, and it is sandwiched between the outer lid 7 and the heat dissipation plate 11 to prevent it from falling out. are doing.
14 is a bottomed cylindrical pot that is removably placed on the rice cooking heater 1; 15 is a pot that is connected to the pot 1 via a pot packing 16
A nozzle 17 is attached to the top surface of the pressure lid that airtightly covers the upper opening of the pot 4, and a pressure adjustment weight 18 is detachably set at the tip of the nozzle 17 to adjust the internal pressure of the pot 14. Reference numeral 19 denotes a holding shaft, which is provided on the upper center surface of the pressure lid 15 and is fixed to the connecting shaft 20 via the pressure lid 15. Reference numeral 21 denotes an inner lid, and an inner lid packing 22 that removably fits on the connecting shaft 20 is attached to the central through hole, and the outer peripheral wall is supported by the pan packing 16. Note that the holding shaft 19 is the holder packing 1.
It has a structure that allows it to be removably fitted with 3.

Here, the upper outer peripheral flange portion of the protective frame 2 is
As shown in the figure, the inner circumference 2b is higher than the height A of the outer circumference 2a.
A convex portion 2b is formed on the inner circumferential portion 2b so that the height B is high.
and is installed on the upper frame 5, and forms a dew catch groove 5a lower than the outermost edge end from the outermost edge of the outer circumference 2a of the flange portion of the protective frame 2 to the outer circumference. The distance between the height C and the lower surface of the upper outer periphery of the pot 14 is widened at the outer periphery to make it easier to insert fingers. Further, a narrow gap is provided at the inner circumference to prevent heat accumulated between the pot 14 and the protective frame 2 from being released, and to prevent water from entering from the outer circumference.

As is clear from the above configuration, according to the present invention, by forming the upper flange portion of the protective frame so that the inner circumferential portion is higher than the outer circumferential portion, heat radiation from between the pot and the protective frame can be prevented. Improved performance by preventing overflowing water from flowing into the protective frame and making it easier to take out by hooking the outer edge of the pot.
It has great practical value, such as being able to take measures against breakdowns and improve operability.
