Description

[Detailed Description of the Invention] The present invention relates to a pressure cooker, and more particularly to a pressure cooker that allows steam inside the pressure cooker to be removed safely and efficiently.

In a conventional pressure cooker, when cooking is finished and the lid is opened, the pressure inside the pressure cooker is lowered by forcibly removing the steam inside the pressure cooker, or the pressure inside the pressure cooker is lowered by forcibly removing the steam inside the pressure cooker. The pressure cooker is opened after being left until the pressure naturally drops. Therefore, if the lid is to be opened in a hurry, the steam inside the pressure cooker must be forcibly removed to lower the pressure. For this reason, especially when the pressure inside the pressure cooker is high, there is a sense of fear due to the steam being blown out due to the way the steam inside the pressure cooker is vented, and concerns about burns caused by the boiling liquid inside the pressure cooker. There were drawbacks such as the food being cooked to a boil due to re-boiling in the pressure cooker, and the risk of accidentally operating the steam vent during cooking.

The present invention relates to a pressure cooker that eliminates the above-mentioned drawbacks.

An embodiment of the pressure cooker of the present invention will be described below with reference to the drawings.

The pressure cooker of the present invention has a steam vent hole 3 on the side of the steam vent valve main body 1 located inside the pressure cooker 2,
An insertion hole 7 for the operating part 6 of the operation valve 5 which also serves as a steam vent is provided on the side of the steam vent valve main body 1 located outside the pressure cooker 4, and a steam valve spring is installed so as to always close the steam vent hole 3. 8 biases the steam valve 9 to arrange the steam valve 9 in the steam vent valve main body 1, one end of the operating valve spring 10 is brought into contact with the steam valve 9, and the other end of the operating valve spring 10 is brought into contact with the steam valve 9. The operation valve 5 is brought into contact with the operation valve 5, the operation part 6 of the operation valve 5 is inserted into the insertion hole 7 of the steam release valve main body 1, and the operation valve 5 is arranged so as to be operable from the outside by the operation part 6, and the steam is released. A valve 11 is formed, and the steam vent valve 11 is arranged at a predetermined position on a lid 12 of the pressure cooker.

In addition, in the above configuration, the operating valve spring 10
The spring pressure of the steam valve spring 8 is set higher than that of the steam valve spring 8, and when the pressure inside the pressure cooker 2 becomes lower than the set pressure, the steam vent hole 3 is unclosed by the steam valve 9, and the pressure inside the pressure cooker 2 is released. The steam valve spring 8 and the operating valve spring 10 are made of compression springs.

In the pressure cooker constructed as described above, the operating portion 6 of the operating valve 5 of the steam vent valve 11 is arranged as shown by the arrow a in FIG.
When the pressure inside the pressure cooker 2 is higher than the set pressure, the steam valve 9 is pressed by the pressure b higher than the set pressure inside the pressure cooker 2, as shown in FIG. The steam valve 9 does not move due to the spring pressure of the operation valve spring 10 acting on the steam valve 9, and the pressure inside the pressure cooker 2 decreases over time (the temperature inside the pressure cooker decreases). ), and when the pressure in the pressure cooker 2 becomes lower than the set pressure, the steam valve 9 is pressed by the pressure c lower than the set pressure in the pressure cooker 2. The spring pressure of the operating valve spring 10 was greater than the pressure of the operating valve spring 10, and the operating valve spring 10 moved the steam valve 9 as shown in FIG. 3, releasing the closure of the steam vent hole 3 by the steam valve 8. It operates to remove steam from inside the pressure cooker 2. In addition, in Fig. 3, the arrow d
indicates the passage through which steam escapes.

As described above, according to the present invention, there is a valve body that is provided inside and outside of the cooker and has a hollow interior, and a steam vent that is provided inside the cooker of the valve body so as to communicate between the inside of the valve body and the inside of the cooker. a hole, a passage hole provided on the outside of the cooking device of the valve body so as to communicate between the inside of the valve body and the outside of the cooking device, and a passage hole provided inside the cooking device of the steam vent hole to open and close the steam vent hole. a vent valve; a means housed within the valve body for biasing the steam vent valve in the direction of closing the steam vent hole; an operating valve that opens and closes the steam venting hole by the steam venting valve when operated by the steam venting valve; and an operating valve that is provided between the operating valve and the steam venting valve and biased in a direction to separate the two, and is configured to be elastic and retractable. Since the steam venting device is provided with a steam venting device consisting of an elastic member, when the pressure inside the cooker is low to a certain extent, the steam venting valve is operated via the elastic member by operating the operation valve, and the steam venting hole is opened by operating the valve. It is opened against the force of the biasing means, and the interior of the cooking device is brought into communication, so that steam within the cooking device can flow into the valve body through the steam vent hole and flow out of the cooking device through the insertion hole.

Also, when the pressure inside the cooker is high to a certain extent, the steam release valve is pressed against the valve body by the pressure of the cooker, and the steam release hole is closed, so that even if the operation valve is operated, the operating force is elastic. The steam vent hole will be kept closed simply by being absorbed into the member.

Therefore, when the pressure inside the cooker is high, the steam release operation cannot be performed and the steam release hole remains closed, so if the pressure inside the cooker is high, the steam may be released by mistake, causing the food to be blown out along with the steam. Inconveniences such as burns or staining the surrounding area can be reliably prevented.

Furthermore, the steam vent valve used in the present invention is compact and easy to install because each part is housed within the valve body.
