Description

[Detailed explanation of the device] This device is designed by attaching a separate auxiliary weight for pressure adjustment in the shape of a short cylinder to the outer periphery of the valve weight provided on the lid of the pressure cooker. The present invention relates to an improvement of a pressure regulating device for a pressure cooker of the type described above.

As described above, the present invention has a valve body that can freely move toward and away from the upper end valve port of the fumarole pipe provided in the lid of the pressure cooker.
In a type of pressure cooker in which a separate auxiliary weight for pressure adjustment is fitted and attached, a substantially U-shaped spring is installed within the inner circumferential wall of the auxiliary weight, which has a substantially short cylindrical shape. The both sides of the auxiliary weight are fitted so that they can move forward and backward elastically so that they protrude moderately from the inner circumferential wall surface of the auxiliary weight, so that when the auxiliary weight is attached to the outer periphery of the weight, the outer periphery of the auxiliary weight This is a pressure adjusting device for a pressure cooker characterized by a structure in which a protrusion with an inclined surface formed in the slanted surface is engaged with a spring fitted into the inner circumferential wall of the auxiliary weight.

In general, the pressure of a pressure cooker is determined by the weight of a weight having a valve body that can freely move toward and away from a valve opening at the upper end of a blow pipe provided in a lid.

In this invention, a light weight serves the original role of cooking rice at low pressure (low temperature), and a separate auxiliary weight is detachably fitted to the outer circumference of the weight. In the pressure adjustment device of a pressure cooker, which is made suitable for high-pressure (high-temperature) cooking of vegetables, meat, seafood, etc. by adding a An auxiliary weight for high pressure is added, and a spring is fitted in a specific shape into the inner peripheral wall of the auxiliary weight,
This spring engages with the slanted ridge formed on the outer periphery of the low-pressure weight, so that the auxiliary weight will not fall off even if the pressure cooker is turned upside down or together with the lid. That is.

Conventionally, a structure in which a separate auxiliary weight was simply fitted onto the outer circumference of the original low-pressure weight (for example, Utility Model 52-
No. 28656) is known, but in this method, the auxiliary weight is simply inserted into the outer periphery of the original low-pressure weight, but the pressure cooker can be used together with the lid, or When only the lid is turned upside down, the auxiliary weight easily falls off and there is a risk of loss, which is impractical.

In addition to lightweight weights, there are also known weights that are as heavy as two weights and can be replaced as needed, but it is troublesome to store and store the weights after cooking.

With this invention, by simply fitting the auxiliary weight to the outer periphery of the original lightweight weight, the auxiliary weight can be assembled without falling off even if the weight is turned upside down, so it is not necessary to prepare the weight separately. Compared to this, the number of parts is reduced, it is convenient to store and store after cooking, and there is no fear of loss and can be provided at a low cost.

Next, to explain the present invention with reference to the drawings, Fig. 1 is a partially cutaway longitudinal sectional front view illustrating an example in which only the original low-pressure weight is provided on the lid of a pressure cooker, and is inserted into the lid 1. A weight 5, which has a valve body 4 screwed into the center of the upper end valve port 3 of the fumarole pipe 2 that can be moved toward and away from the upper end, is placed between the upper end valve port 3 of the fumarole pipe 2 and the outer circumferential side of the fumarole pipe 2. Insert across the exhaust gap.

In FIG. 1, 6 is a handle for the weight 5, into which the male threaded rod portion 7 of the valve body 4 is fitted, and this male threaded rod portion 7 is screwed into the center of the weight 5. The weight 5 is fitted onto the outer circumferential side of the fumarole pipe 2 so that the valve portion of the valve body 4 can freely open and close towards and away from the upper end valve port 3 of the fume pipe 2.

As shown in FIG. 3, the weight 5 has an auxiliary weight support ridge 8, which will be described later, protruding from the periphery of its flat end, and also has a ridge 8, which will be described later, on the periphery of the weight 5, above the periphery 8 of the flat end. A projecting edge 9 with an inclined surface for retaining the spring of the auxiliary weight is provided.

Figure 2 shows an auxiliary weight 10 on the outer circumference of the weight 5 in the present invention.
The figure shows the state in which the auxiliary weight 10 is fitted and attached, and the auxiliary weight 10 is formed into a substantially short cylindrical shape as shown in FIGS.
A groove 11 is formed in the inner peripheral wall of the groove 11, and a spring 12 is formed in the groove 11 in a substantially U-shape as shown in FIG.
The spring is provided so that both side portions 13.13 of the spring can be elastically moved back and forth so that they protrude inwardly from the inner circumferential wall surface of the auxiliary weight 10 to an appropriate extent.

In Fig. 4, 14 is a concave groove 11 into which the spring is inserted.
This is an internal protrusion formed on the lower part of the weight 5, and is a part that is placed on and supported by the peripheral edge 8 of the flat end of the weight 5.

In addition, when the auxiliary weight 10 is inserted into the outer circumferential side of the weight 5, the engaging portion 15 located above the groove 11 is guided by the slope 16 of the slanted surface flange 9 of the weight 5 to assist. The inner circumferential wall of the weight 10 with the spring fitting groove 11 is slid relatively lightly to facilitate fitting of the auxiliary weight 10.

Since the present invention has the above-mentioned structure, when cooking rice etc. at low pressure, it is operated with the original weight 5 installed (Fig. 1), and then at high pressure. When cooking at a high degree of dryness, the auxiliary weight 10 may be pushed in from above so as to fit on the outer periphery of the weight 5.

That is, when pushing the auxiliary weight 10 toward the outer circumference of the weight 5 in this manner, the engaging portion 15 of the auxiliary weight 10 is guided by the inclined surface 16 of the ridge 9 of the weight 5 and is easily pushed into the weight. The internal protrusion 14 of the auxiliary weight 10 slides along the outer circumferential side of the weight 5.
It is received and inserted into the protruding edge 8 of the lower end of.

At the same time, the spring 12 fitted into the concave groove 11 of the auxiliary weight 10 is elastically secured at both sides 13 and 13 by the ridge 9 attached to the inclined surface 16 of the weight 5, so that the lid portion 1 together with the pressure cooker, or even if only the lid 1 is turned upside down, the auxiliary weight 10 can be safely held without falling off.

To remove the auxiliary weight 10, push the auxiliary weight 10 slightly laterally with respect to the weight 5 and press both sides 13.13 of the spring 12.
One of them is elastically retracted into the groove 11, and the auxiliary weight 10 is pulled up a little, and then the side opposite to the front is pushed laterally again to both sides 13 of the spring 12.
If the other of 13 is pulled elastically into the groove 11 and the auxiliary weight 10 is pulled up, the spring 1
The engagement between the protrusion 9 and the side portions 13° 13 of 2 is disengaged, and the auxiliary weight 10 can be easily removed.
