JPS591617Y2 - Knobs with horns for pots, etc. - Google Patents

Description

[Detailed explanation of the invention] This invention relates to knobs for pots, pots, etc. that are equipped with a horn that is emitted by steam.

In a pressure cooker, the internal pressure increases as the heating time elapses, and by the time the cooking is finished, the internal pressure increases further and steam is ejected from the pressure regulating valve.

Normally, I watch this steam and turn off the flame, but when I am doing housework in another room while cooking, I often do not notice the steam coming out from the pressure regulating valve, and I end up turning off the heat more than necessary. Not only did the food boil, but in some cases the internal pressure could become so high that it could no longer be handled by the pressure regulating valve, creating a danger.

The same can be said for commonly used pots, etc., although there is no danger from high pressure.Since there is no alarm, it is impossible to know when the gas is sagging, and sometimes there is a danger that the gas will disappear due to bubbling over. .

This idea was conceived in view of the above points,
To provide a knob with a horn that can be used not only for pressure cookers but also for commonly used pots.

This invention for the above purpose is that a ball valve is provided inside the knob body, and this ball valve can be opened and closed by an operating member so that it can be used for pressure cookers and ordinary pans, and that the knob body and seat body are connected to each other. The feature is that a sounding space is formed in the connecting part.

This invention will be explained in detail below using illustrated examples.

Reference numeral 1 denotes a knob body formed by overlapping and fixing a finger plate 2 having a circular planar shape and a cover member 3.

4 is a seat that is airtightly attached to the pot lid side; 5 is a ball valve having an appropriate weight; and 6 is an operating member for the ball valve 5.

The fingerboard 2 is made up of a circular body with a connecting tube 21 projecting downward from the center thereof, and inside the connecting tube 21 is a partition plate with a concave curved upper surface and a valve hole 22 in the center. 23 is integrally formed.

Further, a guide groove 24 for the operating member 6 is provided on the top surface of the circular body.
is formed in the radial direction.

The cover member 3 has an outflow hole 31 in the center, and an inner wall 32 that protrudes from the center of the lower surface and surrounds the outflow hole 31.
There is.

Further, a recess 33 is formed in the side portion, in which the outer end of the operating member 6 is accommodated.

The operating member 6 has an outer end 62 of a plate having an opening/closing hook 61 for displacing the ball valve 5 from the valve hole 22 at the tip.
It is formed into a shape that fits into the recess 33, and is slidably accommodated in the guide groove 24 of the finger board 2.

The seat body 4 has a short cylindrical shape with a threaded circumference, and a top plate 41.
A steam hole 42 is bored in the center.

The finger board 2 and the cover member 3 have a ball valve 5 placed on the partition plate 23, and an operating member 6 placed at a predetermined position on the finger board 2.
After placing the hook 61 in front of the ball valve 5, the cover member 3 is stacked on the finger plate 2 and fixed integrally with screws, thereby forming the knob body 1.

Further, due to the fastening, a valve chamber 11 that is connected to the connecting cylinder 21 is formed within the knob main body.

The knob main body 1 is attached to the seat body 4 by screwing the connecting cylinder 21, and a sounding space 12 is formed between the partition plate 23 and the top plate 41 by this attachment.

Therefore, in the above structure, the ball valve 5 can be moved from the valve hole 22 by the operation member 6, and the ball valve 5 can be used in an ordinary pan or the like with the valve hole 22 open.

Therefore, when used in a pressure cooker, when the steam pressure reaches such a level as to push up the ball valve 5, the steam passing through the sounding space 12 will emit a horn.

Furthermore, when used in an ordinary pot, the ball valve 5 is removed to the side by the hook 61 in advance, so steam passes through regardless of the ball valve 5, and by the time cooking is finished, that is, the amount of steam passing through is high. Then, the sounding space 12 emits a horn.

As mentioned above, this invention provides a ball valve 5 inside the knob body 1 that can be opened and closed from the outside, and also forms a sounding space 12 in the connecting part between the knob body 1 and the seat body 4, so that the pressure cooker can be heated. It is extremely convenient and easy to use as it can be used not only for pots, etc., but also for ordinary pots, etc.

In addition, it is easier to form the sounding space, and the structure is simpler than when it is formed inside the knob body, resulting in fewer failures and sufficient durability for long-term use.
