DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure cooker for preventing boiling juice from leaking outside through a nozzle valve member of a pressure regulating valve.

[0002]

2. Description of the Related Art Generally, there are a slide type, a double lid type, and a drop lid type. These pressure cookers include a container for storing a material to be cooked, and a lid for closing an opening of the container and not leaking the internal pressure to the outside. With body.

[0003] A well-known safety valve is provided on a lid for closing the opening of the container. When the internal pressure exceeds a set value, the safety valve functions to release the internal pressure to the outside. A known weight valve is arranged in the center of the lid. When the internal pressure rises more than necessary, the weight valve as a pressure regulating valve lifts the weight, leaks only unnecessary pressure to the outside, and keeps the internal pressure constant. That is,
Boiled juice is discharged from the inside to the outside at the time of cooking from the pressure regulating valve, so that there is a problem that this boiled liquid is scattered in the cooking device. In order to cope with this, a device for preventing the broth from scattering was attached to the outside of the lid of the weight valve.

A weight valve as a pressure regulating valve attached to the lid of the above-mentioned pressure cooker is a nozzle fixed to a central portion of the lid via a nut and having a central hole for communicating the inside and outside of the container. It has a type valve member and a weight that always closes an upper opening of the valve member. The internal pressure acts on the weight through the central hole of the valve member, and when the internal pressure exceeds a set value, the weight floats up from the valve member and releases the internal pressure to the outside from the upper opening of the valve member.

[0005]

In the case where the hollow is provided in the center of the lid, boiling water and water droplets adhering to the inner surface of the lid collect around the lower portion of the valve member, and eventually, together with the internal pressure, the internal pressure of the valve member. It is discharged to the outside through the central hole and accumulates on the outer surface of the central hollow of the lid.

Since the discharged broth is hot, it is dangerous to touch the cook's hand, and if it flows into the lock valve, it may cause the lock pin not to work properly.

Therefore, an object of the present invention is to solve the above-mentioned disadvantages of the prior art.

[0008]

According to the present invention, in order to solve the above-mentioned problems, means for fixing a boiling prevention device to a lid is used for a pressure regulating valve.

Specifically, the present invention relates to a pressure cooker having at least a weight valve, a lock valve, and a safety valve fixed to a lid, wherein the lid is overlapped on the container and hermetically sealed. A central portion is a concave portion that is concave downward, and a valve member having a central hole of the weight valve is fixed to the concave portion using a nut with a hole, and cooking is performed between the nut on the inner surface of the concave portion and the inner surface of the concave portion. A pressure cooker is provided, wherein a boil preventive device for preventing boiled juice is interposed, wherein the boil preventive device supported by the lid has a shape surrounding the nut and is provided with a fluorine resin.

[0010] Preferably, the juice preventer is in the shape of a dish or cup facing downward.

[0011]

[Function] When the valve member is fixed to the lid via the boil prevention device, the flow direction of the boil and water droplets traveling on the inner surface of the cover becomes downward at the edge of the boil prevention device or the boil prevention portion, and the boil and water droplets are removed. Since it falls by its own weight, it can be prevented from flowing into the central hole of the valve member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 7 shows a configuration exemplifying a slide-type pressure cooker in the basic configuration of a pressure cooker. Pressure cooker 1
Has a container 2 for storing a material to be cooked, and a lid 3 that closes an opening of the container 2 and does not leak internal pressure to the outside. FIG.
As shown in (1), a plurality of engaging pieces 4 extending outward in the radial direction are provided on the opening edge of the container 2 at a distance. Similarly, a plurality of separated engaging pieces 5 are provided on the outer peripheral edge of the lid 3. When the lid 3 is placed on the opening of the container 2, as shown in FIG. 8, the engaging piece 5 of the lid 3 is located between the engaging pieces 4 of the container 2.
The engagement piece 5 of the container 2 moves to the lower side of the engagement piece 4 of the container 2 to be in an overlapping state. The packing 6 is arranged on the inner peripheral side of the lid 3. The packing 6 allows the internal pressure to rise due to heating. That is, the packing 6 functions to prevent the internal pressure from leaking to the outside.

[0013] Handles 7, 7 'are attached to the left and right of the container 2,
Handles 8 and 8 'are also attached to lid 3. At the time of use, the handles 7 and 8 are vertically overlapped. A known safety valve 9 is provided on the lid 3. When the internal pressure exceeds the set value, the safety valve 9
It works to release internal pressure to the outside. A known weight valve 10 is arranged at the center of the lid 3. When the internal pressure of the weight valve 10 as a pressure regulating valve rises more than necessary, the weight 17 rises, leaking only unnecessary pressure to the outside, and keeping the internal pressure constant. The lock valve 11 is arranged on the handle 8 of the lid 3.
The lock valve 11 includes a valve body, that is, a lock pin 12 and a display pin 1.
When the lock pin 12 is raised by receiving the internal pressure, the display pin 13 is also raised, and its tip protrudes from the handle 8 to inform the user that the internal pressure is high.

Referring to FIG. Central hollow 1 of lid 3
4 is provided with a side hole on the inner lower surface of a washer-shaped boil prevention device 19 made of a plate made of aluminum, silicon resin, SUS or the like coated with fluorine 18 on at least the outer surface (or inner surface) thereof. The valve member 16 as the weight valve 10 is fixed to the lid 3 using the nut 15 of FIG. The anti-boiler 19 is made of a 15-25φ disc and has a thickness of 0.5 to 3.0 mm.
