Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a steam release device for a pot.More specifically, by rotating a knob, it can be switched to three types: steam release, whistle notification, and steam release prevention. This invention relates to a steam release device.

(Prior art) The outer periphery of the pot is made into a concave contact surface, the lower outer periphery of the lid is made into a convex contact surface, and the contact between the two is made with water intervening, thereby sealing the pot and the lid. There is a water seal type pot that is in good condition.

With water-seal type pots, when the inside of the pot cools down after cooking, the internal pressure becomes lower than the outside air, making it difficult to open the lid. Therefore, water seal type pots must be equipped with a steam release device.

In the conventionally known water seal type pot steam release device, communication between the inside and outside of the pot is turned on (communication),
It can be switched in three stages: off (closed) and on via a whistle. (For example, Utsukai Showa 61
(Refer to Publication No. 45035) (Problem to be solved by the invention) However, the above-mentioned known steam venting device has a through hole formed in the lid, and a through hole provided near the outer peripheral edge of the rotating and sliding disc. The structure is such that the flute and the through hole are aligned to communicate between the inside and outside, and the through hole is closed by the disc.

For this reason, the following problems have arisen in known steam removal devices.

First, since the contact area between the disc and the lid is large, there is a risk that the disc will stick to the lid, making it difficult to rotate and slide it.

Furthermore, since the whistle is installed near the back of the lid, boiled food tends to get into the whistle and clog it, which could result in the whistle not sounding.

Furthermore, the disk was easily deformed, and there was a risk that the steam closing effect would be insufficient.

Therefore, the purpose of the present invention is to improve the above-mentioned drawbacks of the conventional steam venting device, and to provide a steam venting device for a pan that is easy to rotate and slide, does not clog the whistle, and has a good steam shut-off condition. There it is.

(Means for solving problems) The feature of this invention is the following structure.

A valve member that is fixed to a knob and has a cylindrical part that rotates and slides at least, and a T-shaped part that is formed within the valve member and has two parts that have no opening at the lower end and communicate with the inside and open to the outer periphery of the cylindrical part. a vent hole in the shape of a shape; a flute body installed near a position on one side of the vent opening at the outer periphery of the cylindrical portion; and a seat plate through which at least the cylindrical portion of the valve member is rotatably slidable. , a screw member formed to protrude from the lower surface of the valve member to the back surface of the lid and fixed by a nut on the back surface of the lid; It consists of a ventilation hole that communicates with the letter-shaped ventilation hole to communicate the inside of the pot with the atmosphere, and by rotating and sliding the knob,
It is possible to switch between the inside of the pot and the atmosphere side in three stages: communication via a whistle body, direct communication, and further closure.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing a water seal type pan steam venting device according to an embodiment of the present invention. Furthermore, since the present invention is more effective when applied to a water seal type pan, the embodiments will be explained using the water seal type pan; however, the present invention is not limited to the water seal type pan. do not have.

The pot consists of a main body M and a lid C, and the upper outer edge of the main body M and the lower outer edge of the lid are in contact with each other with water intervening, thereby creating a water seal.

A knob 1 is provided on the lid C. A metal fitting 2, which is a valve member that switches communication by rotating the knob 1, is fixed to the knob 1. The metal fitting 2 consists of an upper fixed part 2A, an intermediate cylindrical part 2B, and a lower threaded part 2C. is T-shaped ventilation hole 3A,
3B and 3C are formed. Incidentally, the metal fitting 2 is not limited to a metal member as shown in this embodiment, but may also be made of synthetic resin or the like as required. Vent holes 3A and 3B
is an opening on the outer periphery of the cylindrical part 2B of the metal fitting 2, and the opening 3
C is open on the lower surface of the threaded portion 2C of the metal fitting 2.
A retaining cap is screwed onto the threaded portion 2C,
An opening 4A is provided at the center of the bottom surface of the retaining cap 4, coinciding with the ventilation hole 3C. A seat plate 5 is provided between the knob 1 and the lid C, and a cylindrical portion 2B of the metal fitting 2 is rotatably and slidably inserted into the seat plate 5. A screw fitting 6 is fixed to the lower end of the seat plate 5, and the screw fitting 6 passes through the lid C and is screwed and fixed on the back surface of the lid C by a fixing nut 7. Note that the screw fitting 6 is not limited to being made of metal, but may also be made of hard synthetic resin if necessary. The fixing nut 7 is provided with an opening 7A. The threaded portion 2C of the metal fitting 2 is inserted into the screw fitting 6, and the stepped portion 6A and the retaining cap 4 collide with each other via the wave washer 8, thereby preventing the screw from coming off.
A flute body 9 is provided in the ventilation hole 3A formed in the metal fitting 2. The same effect can be obtained even if the flute body 9 is provided in the vent hole 3B instead of the vent hole 3A. When the cylindrical part 2B of the metal fitting 2 rotates and slides, a ventilation hole 5A that matches the ventilation hole 3A and the ventilation hole 3B of the metal fitting 2 is formed in the seat plate 5, and the ventilation hole 5A is inserted through the expanded hole 5B. It is open to the atmosphere. A cap 10 having an opening 10A is placed over the outlet end of the expanded hole 5B. A packing P made of fluororesin is provided between the lower end peripheral edge of the cylindrical part 2B of the metal fitting 2 and the upper part of the screw metal fitting 6, so that the cylindrical part 2 of the metal fitting 2B rotates smoothly and at the same time prevents sticking.

The shape of the knob 1 is an oblong oval, which makes it easy to tell whether the steam vent is closed or open, and also makes it easy to rotate it by hand. Note that the shape of the knob is not limited to an ellipse, but may be circular.

In Figure 1, the inside of the pot is opening 7A, opening 4A,
Vent hole 3C, vent hole 3A, flute body 9, vent hole 5A,
