Abstract

The present invention relates to a pressure safety device mounted on the pressure cooker lid. In the conventional pressure cooker lid, an additional pressure covering the pressure discharge nozzle and the nozzle discharge hole is installed to maintain a pressure suitable for cooking. A safety valve is provided that opens when the internal pressure acts over a certain amount in case the discharge hole is blocked by the cooking contents and loses its function.

The present invention is to integrate the safety devices that are divided into two places as described above.

According to the present invention, the valve body 2, the o-ring (4), the nut (3) is fastened to the pressure cooker lid (1) and the pressure relief nozzle (6), the weight ( 10), an o-ring for valve packing (7), a valve seat (5) combined with a nozzle (6) and a screw rod (8) and a spring (9) are assembled to maintain pressure suitable for cooking and its function It is composed of an integrated structure to perform the safety valve to discharge the internal pressure when the loss, the display function to confirm the presence or absence of pressure in the pressure cooker.

Therefore, if the present invention is applied to a large number of protrusions on the lid, the inconvenience of washing the lid is compensated for, the cost is reduced by the reduction of the manufacturing process, and the pressure cooker can be more compactly manufactured.

Description

Integrated pressure safety device for pressure cooker. {Pressure Cooker Pressure-Safety Unit}

The present invention relates to a pressure safety device for a pressure cooker, and more particularly, the pressure cooker is mounted on the lid of the pressure cooker, and the pressure cooker is automatically opened when the pressure rises above a prescribed value and the pressure is suitable for checking and cooking the pressure cooker. Relates to a device.

In general, the pressure cooker cap is equipped with an internal pressure discharge nozzle and a weight blocking the discharge hole of the nozzle so that when the internal pressure of the pressure cooker reaches a pressure suitable for cooking, the internal pressure discharge of the nozzle blocked by lifting the weight is tilted. Open the hole to maintain the pressure suitable for cooking.

However, if the pressure discharge nozzle is blocked by the contents of the pressure cooker during use and loses its function, the internal pressure continues to rise and there is a risk of explosion. Therefore, a separate safety valve is installed for this.

However, as described above, since the internal pressure discharge nozzle, the weight, and the safety valve are separately installed on both sides of the pressure cooker lid, it is not only difficult to manufacture the pressure cooker compactly, but also the inconvenience of cleaning the pressure cooker lid due to the large number of protrusions. The addition of a manufacturing process leads to high costs.

The purpose of the present invention is that the pressure cooker lid is equipped with a pressure-resistant discharge nozzle, a weight, and a safety valve separately to perform the function as an integrated structure, the pressure cooker appearance can be made compact, cost down, pressure cooker It is to provide a safety device for the pressure cooker that does not interfere with the lid cleaning.

The structure of the present invention, which is integrally mounted on the pressure cooker lid, has a valve body (2) and a fastening nut (3) screwed into the pressure cooker lid (1) mounting hole, and the O-ring (4) ) Is inserted.

The valve seat 5 has a valve seat 5 inserted therein from the top into the internal pressure relief nozzle 6 and a valve packing o-ring 7 fitted into the nozzle outer diameter groove in the center of the valve body 2, and the valve rod (below). 8) and the compression coil spring (9) is inserted into the rod shaft diameter so that one end of the spring is the lower end of the inner diameter of the valve seat (5a) and the other end is through the rod shaft diameter (8a), the valve rod (8) and the nozzle (6) It is screwed in.

When the internal pressure of the pressure cooker rises above the prescribed value, they are compressed upward by the internal pressure to release the o-ring 7 for valve packing, which has been in contact with the valve seat surface 5b. It is discharged to the outside through 5c) and passage 5d. When the internal pressure is discharged and falls below the spring 9 elastic force, the O-ring 7 is seated on the valve seat surface again to stop the internal pressure discharge. (However, when the internal pressure discharge nozzle outlet 6a is blocked by the cooking contents during use of the pressure cooker and fails to function), this process repeats the safety valve function. -Second degree (C)-

Pressure discharge nozzle (6) The weight (10) is installed on the upper surface of the discharge port (6a), the pressure weight suitable for cooking the pressure cooker ex) Pressure resistance is pushed up and tilted 0.9 ~ 1.0kgf / ㎠ as the pressure resistance valve seat It is discharged to the outside through the internal pressure suction hole 5c, the passage 5d, the nozzle suction hole 6d, and the nozzle outlet 6a.

The safety device integrally assembled to the valve seat 5 has a pressure cooker internal pressure equal to the weight of the force of the micro pressure of 0.03 to 0.07 kgf / cm 2, at which pressure the valve seat set protrudes upward. At this time, the O-ring 11 is assembled in the valve seat outer diameter lower end groove 5e to prevent the complete separation to the top and to maintain the airtightness of the sliding portion gap. This protruding phenomenon performs a display function to check the pressure in the pressure cooker. -Second degree (b)-

According to the present invention, by integrating the functional parts applied to both sides of the pressure cooker lid, the manufacturing process is reduced and simplified, thereby significantly reducing the cost, and reducing the protruding portion to compensate for the inconvenience of washing. You can easily determine whether the lid is open by checking.
