Description

[Detailed explanation of the idea] 1 Purpose of the invention The present invention relates to a new pot.

There have been various types of pots, but in view of the fact that pressure cookers are difficult to use and can be dangerous, an object of the present invention is to provide a pot that is as effective as a pressure cooker and can be used safely at all times without boiling over. The purpose is to

2. Structure of the invention The structure and operation of the invention will be explained with reference to the embodiments shown in the drawings.

1 is the body of the pot, and there is a handle 2 on one side of this vessel.
is attached. 3 is a lid body placed on the upper surface of this container 1; 4, 4 is a lid body placed on the upper surface of the container 1; 4, 4 is a lid body 5, 5, 5, 5, whose lower end is pivotally attached to the front and rear sides of the upper end of the container 1; This is a mounting plate, and an arbitrary number of convex portions 6, 6, . . . are formed on this mounting plate. Also,
It is preferable to use a thermally conductive material such as copper for the mounting plates 4, 4. This convex portion 6 is a variable restraining member 7 described later.
This is the stopping point at the upper end of the . The mounting plates 4, 4 are pivoted in the inward and outward directions via the front and rear pivot parts 5, 5, 5, 5. 7, 7... are variable deterrent members made of a shape memory alloy material interposed between the upper surface of the lid 3 and the convex parts 6, 6... of the mounting plates 4, 4, and in the illustrated example, they are used for spiral bombs. It is composed of: The structure of this variable restraint member is arbitrary and may be freely designed to perform the same function. Moreover, the same effect can be achieved even if a shape memory synthetic resin material is used as the variable restraint member.

When the pot of the present invention is not in use, all variable restraining members 7 are removed from the top surface of the lid 3, and the left and right mounting plates 4 are opened from their vertical positions to an outward horizontal position. I'll keep it.

Therefore, when using the pot with boiling ingredients stored in the vessel body 1, after placing the lid body 3 on the top surface of the vessel body 1, the left and right mounting plates 4, 4 are placed perpendicularly above the lid body 3. Then, the variable restraint members 7 are placed on the lid body 3 where the convex portions 6, 6 of the mounting plates 4, 4 are located. After that, the heater starts to burn, but since the variable suppressing member 7 itself remembers its original shape when it reaches a certain temperature, the heating temperature from the container body 1 and lid body 3 is constant. When the temperature reaches a certain level after being transmitted, the variable restraining members 7 completely expand to their original shapes. As a result, the upper end of the variable restraining member 7 is subjected to resistance from the mounting plates 4, 4, so that the lid 3 is pressurized by the reaction, preventing the lid 3 from blowing up due to internal steam, and Body 1 becomes sealed.

If heating to the vessel body 1 is stopped, the variable suppressing member 7
Since the temperature transmitted to the vessel body 1 decreases, the suppressing force is relaxed and reduced, and the sealing of the lid body 3 with respect to the vessel body 1 is released.

3. Effects of the invention The present invention consists of the mounting plates 4, 4, which are constructed by pivoting the lower ends 5, 5 between the front and rear sides of the upper end of the container 1, and the lid body placed on the container 1. A variable restraining member 7 made of a shape memory alloy material is disposed between the variable restraining member 7 and 3, and the variable restraining member changes with a constant change in temperature.
To reliably seal the lid of a pot by forming the shape when the variable suppressing member reaches a predetermined temperature memorized in advance, and to achieve a good cooking effect similar to that when using a pressure cooker. Moreover, it is not dangerous and can be used safely at all times, and its practical effects are great.
