Description

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 liquid from leaking outside through a nozzle type valve member of a pressure regulating valve.

[0002]

2. Description of the Related Art Generally, there are a slide type, a stack lid type, and a drop lid type, but these pressure cookers are containers for containing ingredients to be cooked and lids for closing the openings of the containers and not leaking internal pressure to the outside. It has a body.

A publicly known safety valve is provided on the lid that closes the opening of the container. The safety valve functions to release the internal pressure to the outside when the internal pressure exceeds a set value. A known weight valve is placed in the center of the lid. When the internal pressure of the weight valve as a pressure regulating valve rises more than necessary, the weight floats and leaks only unnecessary pressure to the outside to keep the internal pressure constant. That is,
Since the pressure control valve releases the broth from the inside to the outside during cooking, there is a problem that the broth is scattered in the cooking device. To cope with this, a device for preventing the splash of broth was attached to the outside of the cover of the weight valve.

The weight valve as a pressure adjusting valve attached to the lid of the pressure cooker described above is a nozzle fixed to the 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 formula valve member and a weight for constantly closing the 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 above the valve member and releases the internal pressure to the outside through the upper opening of the valve member.

[0005]

When the lid is provided with a recess in the center thereof, the juice and water droplets attached to the inner surface of the lid gather around the lower portion of the valve member, and eventually, together with the internal pressure, the valve member It is discharged to the outside through the central hole and accumulates on the outer surface of the central recess of the lid.

Since the discharged broth is hot, it is dangerous if it comes into contact with the hands of cooks, and if it flows into the lock valve, it may cause the lock pin to malfunction.

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

[0008]

In order to solve the above-mentioned problems, the present invention uses a means for fixing a boil-preventing device to a lid in a pressure regulating valve.

Specifically, in the present invention, in a pressure cooker that has a pressure adjusting valve fixed to a lid, and seals the lid by overlapping the lid with the container, the pressure adjusting valve is the lid. A pressure cooker characterized by comprising a nozzle-type valve member supported by the lid and having a broth preventer or a broth preventer arranged on the inner surface of which the central part is depressed downward to prevent broth during cooking. provide.

[0010] Preferably, the boil-preventing device is in a downward plate shape or a hat shape, and the boil-protecting device is coated with fluorine. The center of the lid should have a downward recess.

[0011]

[Function] When the valve member is fixed to the lid through the boil-prevention device, the flow direction of the boiled water or water droplets that travels along the inner surface of the lid becomes downward at the edge of the boil-proof device or the boil-water prevention unit, and Since it falls by its own weight, it can be prevented from flowing into the central hole of the valve member.

[0012]

EXAMPLE FIG. 7 shows a constitution of a slide type pressure cooker as an example of the basic constitution of the pressure cooker. Pressure cooker 1
Has a container 2 for containing ingredients to be cooked, and a lid 3 that closes the opening of the container 2 and does not leak the internal pressure to the outside. Figure 8
As shown in FIG. 3, a plurality of engaging pieces 4 extending outward in the radial direction are provided at the opening edge of the container 2 at a distance. Similarly, a plurality of spaced engagement pieces 5 are provided on the outer peripheral edge of the lid body 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, and the lid 3 is rotated when the lid 3 is rotated.
The engaging piece 5 of moves to the lower side of the engaging piece 4 of the container 2 and becomes in a state of overlapping. The packing 6 is arranged on the inner peripheral side of the lid 3. The packing 6 makes it possible to increase the internal pressure by heating. That is, the packing 6 functions to prevent the internal pressure from leaking to the outside.

Handles 7 and 7'are attached to the left and right of the container 2,
Handles 8 and 8'are also attached to the lid 3. At the time of use, both handles 7 and 8 are in a relationship of vertically overlapping. A known safety valve 9 is provided on the lid 3. If the internal pressure of the safety valve 9 exceeds the set value,
It works to release internal pressure to the outside. A known weight valve 10 is arranged in 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 floats up and leaks only unnecessary pressure to the outside to keep 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 an indicator pin 1.

The valve member 16 as the weight valve 10 is fixed to the lid body 3 by using the nut 15. The boil-prevention tool 19 is made of a disk of 15-25φ and has a thickness of 0.5 to 3.0 mm.

In the example shown in FIG. 2, a downward cup-shaped boil-preventing device 19 is used, and a nut 15 similar to the above is arranged in the boil-protecting device 19. Apply fluorine to. The height of the boil-prevention tool 19 made of aluminum, SUS, or silicon resin is set to about 5 mm.

The boil-preventing device 19 shown in FIG. 3 is an inverted M-shaped cup-shaped device, and a nut 15 with a horizontal hole is fastened to the central plane portion of the boil-protecting device 19. Boiled soup preventive device 19
The outer peripheral surface of the is hung down with respect to the lid 3. Fluorine is applied to the inner peripheral surface or the outer peripheral surface of the boil-prevention tool 19 made of aluminum, SUS, or the like, or made of silicon resin.

The example shown in FIG. 4 uses a dish-shaped boil-preventing device 19 made of stainless steel, aluminum or silicon resin, and has a plate thickness of 1 mm and a diameter of 15φ, for example. Fluorine is applied to the broth preventive tool 19.

In the example shown in FIG. 5, the nut 15 having a bottom hole and the broth preventive tool 19 are integrally molded, and the lower surface of the nut 15 is countersunk. In other words, it is a dish shape. The broth preventive tool 19 is attached to the lower surface of the nut 15. Fluorine is applied to the broth preventive tool 19.

In the example shown in FIG. 6, a downwardly facing cylindrical wall as the broth preventive tool 19 is formed integrally with the lid 3. The cylindrical wall may be formed at the time of casting or pressing the lid 3, and the wall thickness may be tapered as shown in the illustrated example, or may be equal. Furthermore, a fluorine film may be applied to the outer surface of the film.

Although the lid 3 in the examples shown in FIGS. 1 to 6 has the recess 14 in the central portion, the recess 14 may be provided at another position of the lid 3. Further, the recess 14 may be one in which the center of an upward arc surface is pushed downward to form a circular flat surface, or one in which the peripheral edge of the lid 3 is raised to form a concave shape like a sliver.

In the example shown in FIGS. 1 to 6, the broth and water droplets attached to the inner surface of the lid 3 flow toward the center of the recess 14, but the direction of the flow is downward due to the broth preventive device 19. And falls due to its own weight. as a result,
No water droplets or broth will flow into the central hole of the valve member 16.

[0022]

[Effect] In the present invention, since the valve member is only fixed through the boil-preventing device or the boil-preventing portion that acts as a boil-out prevention, the assembling procedure is the same as before, and the boil and water droplets cannot be collected in the recess. No pressure cooker can be used safely.
