Description

[Detailed Description of the Invention] The present invention relates to a pressure cooker, and more particularly to a pressure cooker that allows steam in the pressure cooker to be vented safely and efficiently using an operating lever.

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. The pressure cooker is opened after being left until it naturally falls. Therefore, when opening the lid in a hurry, it is necessary to forcibly remove the steam inside the pressure cooker to lower the pressure. In particular, 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 is released from the pressure cooker, and concerns about burns caused by the boiling liquid inside the pressure cooker, and pressure cooking. There are drawbacks such as the food being cooked to a boil due to re-boiling inside the container 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.

In the present invention, the pressure cooker is provided with a plurality of locking claws 2 facing outward on the upper edge of the pressure cooker main body 1 at appropriate intervals in the circumferential direction, and the plurality of locking claws 2 are rotatable. A plurality of inward locking pawls 3 are formed on the periphery of the lid 4 at appropriate intervals in the circumferential direction, and a handle 6 is attached to the upper surface of the cover 4, and a predetermined length of M4 is A steam vent valve 7 is disposed at the steam vent valve body 8 of the steam vent valve 7, and a steam vent valve spring 10 is attached to the steam vent valve body 8 of the steam vent valve 7 so as to always close the steam vent hole 9 formed in the steam vent valve body 8. A lever spring 13 for pressing the steam valve 11 at a predetermined set pressure is attached to an operating lever 12 that presses the steam valve 11 and performs a steam release operation. One end of the lever 12 is pivotally connected to the handle 6, and the other end of the operating lever 12 is provided with an operating knob 14.

In the above configuration, the lever spring 13 has a C-shaped mounting plate 16 attached to one end thereof, which contacts the steam valve 11 of the steam vent valve 7, and the other end attached to the operating lever 12. The spring pressure of the lever spring 13 is set higher than the spring pressure of the steam valve spring 10, and when the pressure inside the pressure cooker main body 1 falls below the set pressure, the steam vent hole by the steam valve 11 is opened. The steam valve spring 10 and the lever spring 13 are compressed springs.

In the pressure cooker configured as described above, when the operating lever 12 is pressed in the direction of arrow a as shown in FIG. If the pressure is higher than the set pressure, the steam valve 11 of the steam vent valve 7 is pressed by the pressure higher than the set pressure in the cooker main body 1, and the steam valve 11 is moved by the lever spring pressure acting on the steam valve 11. If the pressure inside the cooking device main body 1 decreases due to a drop in the temperature inside the cooking device main body 1, and the pressure inside the cooking device main body 1 becomes lower than the set pressure, the pressure inside the cooking device main body 1 becomes lower than the set pressure. Although the steam valve 11 is pressed by the low pressure C, the cooking device main body 1
The spring pressure of the lever spring 13 is greater than the pressure inside the operating lever 1.
2 is transmitted to the steam valve 11, and the steam valve 11
moves as shown in FIG. 4 to release the steam vent hole 9 from the steam valve 11 and vent the steam inside the cooking device main body 1.

In FIG. 4, arrow d indicates a passage through which steam escapes.

Since the pressure cooker of the present invention has the above-mentioned configuration, there is no need to worry about the spouting of steam due to the way the steam is released when opening the lid in a hurry, or the risk of burns due to the boiling liquid inside the pressure cooker spewing out. , it is possible to reliably prevent disadvantages such as cooking food collapsing due to re-boiling in the pressure cooker, causing concerns about accidentally operating the steam vent during cooking, etc. It can be removed safely and efficiently by operation.
