The present invention relates to an improved design of a double safety device of a high pressure cooker, which can prevent safety accidents at the time of opening a lid in various high pressure cookers made of stainless steel or the like.

In general, high pressure cookers (aka pressure rice cookers) have released a number of safety devices to prepare for any safety accidents by discharging the high temperature and high pressure vapor pressure remaining inside before opening the lid when cooking. In addition, the applicant of the present application has already filed an application for the safety device of the high-pressure cooker (Application No .: 1993 Utility Model Registration Application No. 3324).

However, the safety device of the existing high-pressure cooker has only the primary safety means to open the lid after the high-pressure steam discharged through the discharge valve, and in the applicant's prior application design of the high pressure in addition to the primary safety means described above Also disclosed is a means for discharging the steam to the second residual steam, that is, up to pressurization when opening the lid after the discharge, the prior art of the applicant with such a double safety device also had the following improvements.

That is, since the means for discharging the pressurization when the lid is opened after the first high pressure discharge is configured to interlock with each other when the lid is opened, it was difficult to provide reliability in the operation of each of the first and second safety devices. This has been more difficult to provide smooth operation in view of the use of the high-pressure cooker and the device of the present invention is steam discharge containing high pressure water.

That is, the safety device of the applicant-applied high-pressure cooker of the present applicant is to open and close the lid 102 opening and closing lever 104 to the handle portion 103 connected to the lid 102 of the autoclave 101 as shown in FIG. While installed, the opening and closing lever 104 is pushed toward the center of the packing 105 of the lid 102 while interlocking with the slide operation in the center direction to discharge the pressurized pressure that can automatically discharge the remaining steam pressure inside the autoclave 101 Means 106, the pressurizing discharge means 106 is a slide cylinder 110 for connecting the guide piece 109 formed with the exhaust pin 107 and the guide pin 108 on the side with the opening and closing lever 104. It is elastically installed with a spring 111 so that it can slide in the inside, and the pressurization discharge means 106 is a lifting valve 112 and intermittent hole 113 ', which is known as a primary safety device when the lid 102 is opened. The intermittent lever 113 having an integrally connected to the slide barrel 110 to operate the opening and closing lever 104. Autoclave 101 is the situation in use in combination with means for intermittent opening and closing of the lid 102 in accordance with the discharge amount of the vapor pressure in the interior.

This prior art is that when the upper end of the valve 102, the high-pressure steam is first discharged when the lifting valve 112 is released at high pressure and lowered by its own weight, when the user pushes the opening and closing lever 104 As the entire slide barrel 110 is advanced toward the high pressure pot 101, the intermittent hole 113 'and the elevating valve 112 of the intermittent lever 113 are coincided with each other, and the lid 102 is switched to an open state. When the handle 103 is angularly moved for opening, the guide pin 108 formed on the guide piece 109 of the pressurizing discharge means 106 is along the guide groove 114 formed on the lower handle 103. While moving forward, the packing 105 on the outer edge of the autoclave 101 is pushed toward the center to finally discharge the pressurized pressure. In this case, the guide piece 108 is first advanced when the intermittent lever 113 is advanced and the spring 111 is moved forward. ) Is compressed so that the packing 105 can be precisely exerted by exhibiting a predetermined modulus of elasticity. Pushing hagieneun was the difficulty, the slide tube 110 could be a drawback that a long time between the smoothness of the operation or the like by using both the moisture contained in the steam also decreases according as the guide piece 109 is operating within.

In addition, such a configuration has to manufacture the slide barrel 110 and the guide piece 109 together with the handle portion 103, so that the number of parts increases with the consumption of the mold cost, which leads to a price increase factor, thereby providing an advantage in price competitiveness. There was a difficulty in divination.

Therefore, in the present design, in the dual safety device of the high pressure cooker as described above, the operation safety is prevented from being deteriorated due to structural defects of the primary safety means and the secondary pressurizing discharge means when the lid is opened, and the number of parts is reduced. In order to minimize the cost of the manufacturing cost by reducing, the main feature of the construction of the present invention is to form a guide portion for the primary safety means and the secondary pressurizing discharge means can be operated separately on the handle portion of the autoclave each component As it is possible to be built-in, when described in detail with reference to the accompanying drawings the preferred embodiment of the present invention as follows.

2 is an exploded perspective view to which a preferred embodiment of the present invention is applied, and an upper handle 3 mounted on one side of a lid 2 opened and closed at an upper portion of the autoclave 1, and a lower portion mounted on one side of the autoclave 1. The handle 4 has a primary safety device 5 which allows the lid 2 to be opened only when the lid 2 of the autoclave 1 is discharged at the time of opening, and the autoclave 2 as a second. The secondary safety device (6; or pressurization discharge means) is installed to discharge the remaining pressurization therein, the primary safety device (5) is on the locking recess (7) formed on the lower handle (4) The slide locker 8 of the upper handle 3 selectively slides to form a slide guide portion 9 of the recessed type of the upper handle 3 so that locking / unlocking can be performed, and the slide guide portion ( Opening lever 11 capable of operating the slide locker 8 while forming an opening 10 in one side of the 9) angular movement Is assembled by fitting and is connected to the slide locker (8).

On the side of the slide locker 8, an intermittent hole 8a is provided so that the slide movement of the slide locker 8 can be selectively interrupted in accordance with the lifting operation of the lifting valve 12 installed on the lid 2 so as to be elevated. It is formed is assembled to be in contact with the outer surface portion of the elevating valve (12).

In addition, under the slide guide portion 9 to which the slide locker 8 of the upper handle 3 is coupled, another slide guide portion 9 'on which the secondary safety device 6 can be assembled is formed. .

The slide guide portion 9 'is a guide hole 13 formed in the lower handle 4 toward the center of the high pressure cooker 1 and at the same time inclined in the opening direction of the lid 2 guide hole 13 formed The discharge piece 15 having a guide pin 14 in the lower portion is assembled to the lower side when the lid (2) is opened, the slide is elastically coupled forward with the spring 16 interposed therebetween, The front side of the discharge piece 15 to form a discharge pin 18 to push the packing 17 while selectively contacting the packing 17 attached to the inner periphery of the lid (2).

In the figure, reference numeral 19 shows a high pressure steam discharge valve attached to the existing high pressure cooker (1).

The present invention, which can be configured as described above, is applied to various autoclaves 1 to ensure maximum safety when opening the lid 2, and to minimize operational reliability, manufacturing cost, and the like, This will be described in more detail below.

When using the autoclave (1) to cook for a predetermined time and then open the lid (2), the autoclave (1) using the high pressure steam discharge valve (19) attached to the lid (2) ) Exhaust high pressure steam inside.

As the steam is discharged, the pressure inside is lowered, and the lifting valve 12 on one side of the lid 2 is also lowered by its own weight as the pressure decreases.
